THE COMPANY

RYMAC Mortgage Investment Corporation was incorporated in the state of Maryland on July 1, 1988 and has elected to be taxed as a real estate investment trust ("REIT") under the Internal Revenue Code of 1986, as amended (the "Code"). Prior to 1994, the Company was primarily engaged in making investments in mortgage derivative securities and, to a lesser extent, mortgage related investments. Due to difficulties encountered in its historical business and a substantially altered mortgage-backed securities market, since mid-1994 the Company has been investigating transactions which would allow the Company to enter into alternative businesses. The principal executive offices of the Company are located at 100 N. Fourth Street, Suite 813, Steubenville, Ohio 43952 and the telephone number is (800) 666-6960.

THE ACQUISITION

GENERAL

The Company has entered into the Asset Purchase Agreement with Navistar to acquire substantially all of the assets and liabilities of Navistar's Columbus Plastics Operations. In order to consummate the Acquisition, the Company, among other things, will be required under the terms of the Asset Purchase Agreement to reincorporate in Delaware. To effect the reincorporation, the Company has entered into an Agreement and Plan of Merger (the "Merger Agreement") with Core Materials, a Delaware corporation and a wholly-owned subsidiary of the Company. Pursuant to the terms of the Merger Agreement, the Company will be merged with and into Core Materials with Core Materials as the surviving corporation and each outstanding share of Company Common Stock being converted into the right to receive one share of Core Materials Common Stock. As soon as practicable after the Merger, the Acquisition will be consummated and as part of the consideration to be paid to Navistar Core Materials will issue 4,264,000 shares of Core Materials Common Stock to Navistar, representing approximately 45% of the total number of shares of Core Materials Common Stock issued and outstanding on a fully diluted basis after giving effect to the Acquisition. The purchase price payable under the Asset Purchase Agreement is subject to adjustment as described below under "PROPOSAL NO. 1--APPROVAL OF THE ACQUISITION--The Asset Purchase Agreement-- Purchase Price Adjustments."

The Company's stockholders are asked to approve the terms of the Asset Purchase Agreement and the consummation of the transactions contemplated thereby, including the Merger and the Stock Issuance. If the terms of the Asset Purchase Agreement are not approved by the Company's stockholders, neither the Acquisition nor the Merger will be consummated. In addition, consummation of the Merger is a condition to Navistar's obligations under the Asset Purchase Agreement; therefore, if the Merger is not approved by the Company's stockholders, Navistar will not be obligated to consummate the Acquisition.

RECOMMENDATION OF THE COMPANY'S BOARD OF DIRECTORS

The Company's Board of Directors has unanimously approved the Asset Purchase Agreement and the transactions contemplated thereby, including the Stock Issuance and the Merger and recommends that the Company's stockholders vote in favor of approval and adoption of the Asset Purchase Agreement and the Merger Agreement. See "PROPOSAL NO. 1--APPROVAL OF THE ACQUISITION--Recommendation of the Board of Directors."

OPINION OF NOMURA

Nomura Securities International, Inc. ("Nomura"), the financial advisor to the Company, has delivered to the Company's Board of Directors its opinions dated September 6, 1996, September 12, 1996 and the date hereof, to the effect that, as of the dates of such opinions, based upon the assumptions made which did not give effect to Section 1(g)(iii) of the Asset Purchase Agreement (which section is referred to elsewhere herein by the Company as the NOL Adjustment Provision), matters considered and limits of its review, the proposed consideration to be paid by the Company pursuant to the Asset Purchase Agreement is fair to the stockholders of the Company from a financial point of view. For additional information concerning the assumptions made, matters considered and limits of the review by such financial advisor in reaching its opinion and the fees received and to be received by it, see "PROPOSAL NO. 1--APPROVAL OF THE ACQUISITION--Opinion of Nomura" and Annex II attached hereto.

INTERESTS OF CERTAIN PERSONS IN THE TRANSACTIONS

In considering the recommendation of the Company's Board of Directors, stockholders should be aware that certain persons involved with the Acquisition have certain interests in the Acquisition that are in addition to the interests of the Company and the Company's stockholders generally. See "PROPOSAL NO. 1-- APPROVAL OF THE ACQUISITION--Interests of Certain Persons in the Transactions."

THE ASSET PURCHASE AGREEMENT

The Asset Purchase Agreement provides for the acquisition by the Company of substantially all of the assets, properties and business, subject to the assumption of certain liabilities, of Navistar's business conducted at 800 Manor Park Drive, Columbus, Ohio relating primarily to the manufacture, marketing and sale of fiberglass reinforced plastic component parts (the "Assets"). In consideration for the Assets, Navistar will receive upon closing ("Closing") of the Acquisition (1) $25,504,000, subject to adjustment as described below, payable by the Company in the form of a secured promissory note (the "Secured Note") and (2) 4,264,000 shares of Core Materials Common Stock representing approximately 45% of the total number of shares of Core Materials Common Stock issued and outstanding on a fully diluted basis after the Acquisition. The Company may reduce the principal amount of the Secured Note by delivering to Navistar on the date of the Closing (the "Closing Date") by wire transfer of immediately available funds an amount equal to such reduction pursuant to financing arrangements that, in the opinion of the Company and Navistar, would not reasonably be expected to have a material adverse effect on the ability of Core Materials to secure loans for working capital and project finance use after the Closing.

The purchase price payable under the Asset Purchase Agreement is subject to adjustment as described under "PROPOSAL NO. 1--APPROVAL OF THE ACQUISITION--The Asset Purchase Agreement-- Purchase Price Adjustments."

The Asset Purchase Agreement contains certain representations and warranties by Navistar and the Company which will expire at, and not survive, the Closing. Each party's obligation to consummate the Acquisition is subject to a number of conditions, including, among other things, the receipt of satisfactory legal opinions, the accuracy of their respective representations and warranties as of the Closing Date, receipt by the parties of all third party, stockholder and governmental consents and approvals required to consummate the Acquisition and the other transactions contemplated by the Asset Purchase Agreement, the execution and delivery by Navistar and the Company of the Supply Agreement, the Transitional Services Agreement and the Registration Rights Agreement (each as defined below), and the Company and the International Association of Machinists and Aerospace Workers ("IAM") entering into a collective bargaining agreement for the

8

employment of IAM represented employees of the Company at Columbus Plastics and compliance by all parties with their respective obligations prior to the Closing Date. The obligation of the Company to consummate the Acquisition is also subject to the approval of the Company's stockholders of the transactions contemplated by the Asset Purchase Agreement, including the approval of the Merger by the affirmative vote of no less than two-thirds of the Company Common Stock present and entitled to vote at the Special Meeting. The obligation of Navistar to consummate the Acquisition is also subject to, among other things, the Company having consummated the Merger, the Company having terminated the RYMAC Salary Reduction Simplified Employee Pension Plan ("SEP") in accordance with applicable law, the Company having amended its charter and by-laws in a manner satisfactory to Navistar, the Company having effected the registration under the Securities Act, and having obtained approval for listing on the American Stock Exchange, of the shares of Core Materials Common Stock to be issued to Navistar under the Asset Purchase Agreement, each of the individuals serving on the Company's Board of Directors tendering his or her resignation to the Company effective as of the Closing Date. See "PROPOSAL NO. 1--APPROVAL OF THE ACQUISITION--The Asset Purchase Agreement--Representations and Warranties; Conditions to Closing; Amendments; Termination."

For a description of the terms and conditions pursuant to which the respective obligations of the parties to the Asset Purchase Agreement may be terminated, see "PROPOSAL NO. 1--APPROVAL OF THE ACQUISITION--The Asset Purchase Agreement--Representations and Warranties; Conditions to Closing; Amendments; Termination."

Navistar has agreed under the Asset Purchase Agreement to indemnify the Company, its affiliates and each of their respective officers, directors, employees and agents and hold them harmless from any Loss (as hereinafter defined) suffered or incurred by any such indemnified party or to which any such indemnified party becomes subject to the extent directly or indirectly arising from (i) any breach of (or in the event any third party alleges facts that if true would mean Navistar has breached) any covenant of Navistar contained in the Asset Purchase Agreement or the other agreements and instruments contemplated thereby; (ii) any liability of Navistar not specifically assumed by the Company ("Excluded Liabilities") and (iii) any statements or information contained in this Proxy Statement/Prospectus relating to Columbus Plastics or Navistar or its related entities requested by the Company for inclusion in this Proxy Statement/Prospectus and supplied by Navistar, provided the Company presents such information in conformity in form and substance with the information supplied to it by Navistar. The Company has agreed under the Asset Purchase Agreement to indemnify each of Navistar, its affiliates, officers, directors, employees and agents against and hold them harmless from any Loss suffered or incurred by any such indemnified party or to which any such indemnified party becomes subject to the extent directly or indirectly arising from (i) any breach of (or in the event any third party alleges facts that if true would mean the Company has breached) any covenant of the Company contained in the Asset Purchase Agreement or the other agreements and instruments contemplated thereby,

For purposes of the Asset Purchase Agreement, at the time of any Loss, the "Proportionate Share" of each of Navistar, its affiliates, officers, directors, employees and agents shall be the ratio, expressed as a percentage, of the total number of shares of the Common Stock owned by such person at the time of such Loss divided by the total number of shares of the Common Stock issued and outstanding at the time of such Loss. "Loss" means, with respect to any person, any damage, injury, liability, demand, claim, action, cause of action, cost, deficiency, tax, penalty, fine or other loss, payment or expense, whether or not arising out of a claim, including all interest, penalties, reasonable attorneys' fees and expenses and all amounts paid or incurred in connection with any action, demand, proceeding, investigation or claim by any third party (including any government entity) against or affecting such person, together with interest thereon from the date on which such person provides the written notice of the related claim through and including the date on which the total amount of the claim, including such interest, is recovered or recouped pursuant to the indemnity provisions of the Asset Purchase Agreement.

For a more detailed description of the Registration Rights Agreement, see "PROPOSAL NO. 1--APPROVAL OF THE ACQUISITION--Ancillary Agreements-- The Registration Rights Agreement."

SUMMARY OF BUSINESS OF COLUMBUS PLASTICS

Columbus Plastics has historically constituted a part of Navistar's business operations. Columbus Plastics has never existed as a separate entity apart from Navistar. Navistar has used its Columbus Plastics Operations to manufacture fiberglass and plastic component parts for use by Navistar in Navistar's business of manufacturing and marketing of diesel trucks and for sales to third party customers, primarily Yamaha Motor Manufacturing Corporation ("Yamaha"), for use in the personal watercraft business. Prior to the Acquisition, in excess of 60% of all of component parts produced by Columbus Plastics were sold to Navistar at the standard cost basis of Columbus Plastics which was substantially below the market value of such component parts.

SUMMARY OF BUSINESS OF CORE MATERIALS AFTER THE ACQUISITION

In connection with the Acquisition, Core Materials will acquire substantially all of the assets and liabilities, including the property and business, of Columbus Plastics (other than certain excluded assets and liabilities). After the Acquisition, Core Materials will continue to hold the Company's remaining investments in mortgage securities but the principal business of Core Materials will consist of operating the business and property of Columbus Plastics. See "PROPOSAL NO. 1--APPROVAL OF THE ACQUISITION-- Unaudited Pro Forma Combined Financial Information of Core Materials" and "-- Business of Core Materials After the Acquisition."

MANAGEMENT OF CORE MATERIALS

Pursuant to the terms of the Asset Purchase Agreement, the Board of Directors of Core Materials appointed on the Closing Date will have five directors and will consist of the following persons: (i) two persons designated by Navistar; (ii) two persons designated by the Company's existing Board of Directors and (iii) one person to be selected by mutual agreement of Navistar and the Company. See "PROPOSAL NO. 1--APPROVAL OF THE ACQUISITION--Management of Core Materials After the Acquisition."

THE MERGER

GENERAL

One of the conditions to Navistar's obligation to consummate the Acquisition is the reincorporation of the Company in the State of Delaware. To effect this reincorporation, the Company has incorporated Core Materials, a wholly-owned subsidiary of the Company, as a Delaware corporation. If the Asset Purchase Agreement and the Merger Agreement are approved by the Company's stockholders and the other conditions to the Asset Purchase Agreement are satisfied or waived, the Company will be merged with and into Core Materials with Core Materials as the surviving corporation and each outstanding share of Company Common Stock being automatically converted into the right to receive one share of Core Materials Common Stock. The Merger will become effective upon the filing of certificate of merger with the Secretary of State of the State of Delaware and the filing of articles of merger with the State Department of Assessments and Taxation of Maryland ("SDAT") (the "Effective Time"). It is presently anticipated that such filings will be made as soon

11

as practicable after approval and adoption of the Asset Purchase Agreement and the Merger Agreement at the Special Meeting. COMPANY STOCKHOLDERS SHOULD NOT
SEND IN THEIR STOCK CERTIFICATES FOR EXCHANGE UNTIL THEY RECEIVE A LETTER OF TRANSMITTAL FROM THE COMPANY'S EXCHANGE AGENT, AMERICAN STOCK TRANSFER & TRUST CO., WITH INSTRUCTIONS REGARDING THE EXCHANGE OF STOCK CERTIFICATES.

COMPARISON OF STOCKHOLDER RIGHTS

The rights of stockholders of the Company currently are governed by Maryland corporation law, the Company's Amended and Restated Articles of Incorporation, as amended, and the Company's Amended and Restated By-laws, as amended. Upon completion of the Merger, stockholders of the Company will become stockholders of Core Materials, and their rights as stockholders of Core Materials will be governed by Delaware corporation law, the Core Materials Certificate of Incorporation and the Core Materials By-laws.

Material differences between the rights of stockholders of Core Materials and the rights of stockholders of the Company include the following: (i) Maryland law provides stockholders with more limited rights of inspection than does Delaware law; (ii) the By-laws of the Company require that a majority of the Company's Board of Directors be unaffiliated directors, whereas Core Materials' By-laws do not; (iii) Maryland law provides that any director or officer may be removed with or without cause by the affirmative vote of a majority of all the votes entitled to be cast in the election of directors, unless the Charter of the corporation provides otherwise, which the Articles of Incorporation of the Company does not, whereas the Certificate of Incorporation and By-laws of Core Materials provide that a director may be removed with or without cause by the holders of at least 80% of the voting power of the outstanding shares of capital stock of Core Materials entitled to vote generally in the election of directors; (iv) as permitted by Maryland law, the Company's Articles of Incorporation limit the liability of officers to the corporation or its stockholders for money damages to the same extent as directors, whereas under Delaware law the liability of officers may not be limited; (v) the By-laws of the Company contain a limitation on the ability of the Company to incur indebtedness, whereas the By-laws of Core Materials do not contain a provision restricting the incurrence of indebtedness; (vi) the Articles of Incorporation of the Company contain provisions restricting the transfer of shares of Company Common Stock in order to preserve the Company's status as a REIT, whereas Core Materials' Certificate of Incorporation does not contain a similar provision;
(vii) Core Materials' Certificate of Incorporation contains provisions prohibiting certain transfers of Core Materials Common Stock intended to preserve the corporation's NOLs, whereas the Company's Articles of Incorporation does not contain a similar provision; (viii) Core Materials will be subject to Delaware's annual franchise tax (which under current law will be approximately $34,800 per year), while the Company is not subject to any similar tax in Maryland; (ix) under Maryland law, the exclusive power to change the By-laws may be left with the stockholders, vested in the directors or shared by both groups, while under Delaware law, the power to change the By-laws belongs to the stockholders and, although it may be shared with directors, the stockholders may never be divested of this power; (x) Maryland permits the charter of a corporation to deny all voting rights to shares of any class of stock, while Delaware prohibits denying voting rights to shares of a class in connection with an amendment to the certificate of incorporation if the amendment would change the par value of the class or would adversely affect the powers, preferences of special rights of the class; and (xi) in connection with the voluntary dissolution of the corporation, Maryland law requires the approval of stockholders by the affirmative vote of two-thirds of all the votes entitled to be cast on the matter, while Delaware law requires the approval of stockholders by the affirmative vote of a majority of the votes entitled to be cast on the matter. The material similarities and differences between Maryland corporation law and the Company's Articles of Incorporation and By-laws, on the one hand, and Delaware corporation law and the Core Materials Certificate of Incorporation and By-laws, on the other, which should be considered in connection with the Merger, are summarized in "PROPOSAL NO. 2--APPROVAL OF THE MERGER."

CERTAIN FEDERAL INCOME TAX CONSEQUENCES

The Company's stockholders will not recognize gain or loss for federal income tax purposes as a result of the Acquisition. In addition, the Company does not anticipate incurring any federal income tax liability as a result of the Acquisition. However, after the Acquisition, the Company will no longer elect to be a REIT for federal income tax purposes.

12

The Merger must qualify as a reorganization under Section 368 of the Internal Revenue Code of 1986, as amended (the "Code"), for stockholders to not be required to recognize a gain from their exchange of the Common Stock of the Company for the Common Stock of Core Materials and for Core Materials to succeed to the tax attributes of the Company. Although the matter is not free from doubt, the Merger should be treated as a reorganization for purposes of Code
Section 368. Accordingly, stockholders should not recognize gain or loss upon their exchange of Common Stock of the Company for Common Stock of Core Materials. In addition, Core Materials should succeed to the tax attributes of the Company including its NOLs, earnings and profits, and capital loss carryforwards. However, the Company has not requested a ruling that the Merger so qualifies and it is possible that the Internal Revenue Service (the "IRS") will disagree that the Merger qualifies as a reorganization. See "PROPOSAL NO. 2--APPROVAL OF THE MERGER--Federal Income Tax Consequence of the Merger and the Acquisition--The Merger."

The consideration paid to Navistar under the Asset Purchase Agreement has been structured such that Navistar should be treated as owning less that 50% of the stock value of Core Materials. If the consideration paid to Navistar results in Navistar owning more than 50% of the stock value of Core Materials or results in Navistar and certain stockholders of the Company owning more than 50% of the stock value of Core Materials then a change in control will occur for purposes of Code Section 382 (a "Change in Control"). If a Change in Control occurs, Core Materials' ability to utilize the NOLs of the Company will be severely restricted. No ruling has been or will be sought from the IRS. See "PROPOSAL NO. 2--APPROVAL OF THE MERGER--Federal Income Tax Consequences of the Merger and the Acquisition."

The Asset Purchase Agreement contains certain adjustments to the amount of Core Materials Common Stock that Navistar can receive that are designed to prevent the consideration paid to Navistar from resulting in a Change in Control. In addition, the Certificate of Incorporation of Core Materials contains certain restrictions on share ownership to prevent a Change in Control. However, it is possible that certain non stock consideration that Navistar is receiving would be required to be treated as stock for purposes of determining whether the Acquisition will result in a Change in Control. In addition, there can be no assurance that the restrictions contained in the Asset Purchase Agreement or in the Certificate of Incorporation will prevent a Change in Control. See "PROPOSAL NO. 2--APPROVAL OF THE MERGER--Federal Income Tax Consequences of the Merger and the Acquisition--Utilization of Net Operating Losses and Capital Loss Carryforwards."

ACCOUNTING TREATMENT

Based upon the terms of the proposed Acquisition, for financial reporting and accounting purposes the transaction will be accounted for as a reverse acquisition whereby Columbus Plastics will be deemed to have acquired Core Materials. However, Core Materials, subsequent to the merger, will be the continuing legal entity and registrant for both Securities and Exchange Commission filing purposes and income tax reporting purposes. Consistent with reverse acquisition accounting treatment, Core Materials will carry forward the historical basis of the acquired assets and assumed liabilities of Columbus Plastics and will revalue the basis of its net assets to fair value. Should there be an additional contingent earn-out adjustment, it will be accounted for by increasing the amount of the Secured Note, and by reducing the amount of Core Materials' retained earnings. See "PROPOSAL NO. 1--APPROVAL OF THE ACQUISITION--Unaudited Pro Forma Combined Financial Information of Core Materials."

NO APPRAISAL RIGHTS

Holders of shares of Company Common Stock will not have any statutory appraisal rights under Maryland law to elect to have the fair value of their shares of Company Common Stock judicially appraised and paid to them in cash in connection with or as a result of the matters to be acted upon at the Special Meeting. See "PROPOSAL NO. 2--APPROVAL OF THE MERGER--No Dissenters' Rights of Appraisal."

(1) Columbus Plastics provides Navistar's truck assembly operations with all of its sheet molding composite plastic component requirements, which represents greater than 60% of its output in all periods presented, at standard cost, with the remainder sold to unrelated third party customers at negotiated prices.

(2) Interest, income taxes and earnings per share have been omitted because Columbus Plastics was not a separate stand alone division or subsidiary of Navistar and was generally not accounted for separately. In addition, Navistar's systems and procedures do not provide sufficient information to develop a reasonable cost allocation of income taxes, corporate debt and interest expense.

(1) The provision for income taxes reflects the statutory Federal tax rate. However, due to Core Materials' substantial net operating losses and capital loss carryforwards, actual Federal tax payments will be de minimis until such loss carryforwards are fully utilized or expired.

(2) On a pro forma basis there would be no difference between the primary and fully diluted earnings per share.

COMPARATIVE PER SHARE DATA

The following table of certain comparative per share data is based upon the data used in compiling the Unaudited Pro Forma Combined Financial Statements and upon the respective financial statements of Columbus Plastics and the consolidated financial statements of the Company incorporated by reference herein, and should be read in conjunction with those financial statements and the related notes. Historical per share data of Columbus Plastics is not presented as Columbus Plastics was not a stand alone division or subsidiary of Navistar and was generally not accounted for separately during the periods presented. Historical per share data of Core Materials is not presented as Core Materials has had no operations.

RISK FACTORS

In addition to the other information contained in this Prospectus/Proxy Statement, the stockholders of the Company should carefully consider the following factors in determining whether to approve and adopt the Asset Purchase Agreement and the transactions contemplated thereby and the other proposals set forth in this Prospectus/Proxy Statement.

CYCLICAL MARKETS FOR PRODUCTS

The markets for and profitability of Columbus Plastics products have been and are likely to continue to be cyclical. Periods of high demand, high capacity utilization and increasing operating margins tend to result in new plant investment and increased production, followed by periods of declining demand, declining capacity utilization and declining margins until the cycle is repeated. A downturn in the economy could materially adversely affect Columbus Plastics' business.

RAW MATERIALS AND DEPENDENCE ON SUPPLIERS

Columbus Plastics produces components using a variety of processes and raw materials. Its raw materials include polyester resin, fiberglass rovings and adhesives. The prices of such raw materials have fluctuated significantly in the past. Significant fluctuations in the price of such raw materials, without a coincident ability to reflect such fluctuations in selling prices, could have a material adverse affect on Columbus Plastics' results of operations.

Columbus Plastics relies on a limited number of suppliers to provide raw materials used to manufacture its products. Although Columbus Plastics believes it has access to an ample supply of these raw materials, in the event that Columbus Plastics can not obtain adequate quantities from its existing suppliers, there can be no assurance that Columbus Plastics would be able to access alternative sources of supply within a reasonable time or at commercially reasonable rates. The unavailability of adequate commercial quantities, the inability to develop alternative sources, or a significant increase in the price of raw materials could have a material adverse effect on Columbus Plastics ability to manufacture products. See "PROPOSAL NO. 1--APPROVAL OF THE ACQUISITION--Business of Columbus Plastics--Products."

COMPETITION

Columbus Plastics' industry is highly competitive. Columbus Plastics faces competition from a number of companies, some of whom are larger and have greater financial resources, research and development facilities, and manufacturing and marketing capabilities than Columbus Plastics. In addition, many original equipment manufacturer ("OEM") customers manufacture, engineer and design some components and could expand this activity, thereby reducing opportunities for Columbus Plastics. Furthermore, there can be no assurance that developments by Columbus Plastics' competitors or potential competitors will not make Columbus Plastics' products obsolete. Columbus Plastics' ability to compete effectively will depend upon its products' functional features and upon the ability of Columbus Plastics to attract and retain qualified personnel, to maintain and expand the capabilities of its technologies, to sell existing products to new customers, to service its new customers and to develop new products for existing customers. No assurance can be given that Columbus Plastics will be able to continue to compete effectively or that Columbus Plastics' results of operations will not be adversely affected by increased competition in its industry. See "PROPOSAL NO. 1--APPROVAL OF THE ACQUISITION--Business of Columbus Plastics--Industry."

NEED TO RESPOND TO TECHNOLOGICAL CHANGE

The markets for Columbus Plastics' products are characterized by rapidly changing technology and evolving industry standards. Columbus Plastics' future success will depend in part upon its ability to enhance existing products and to introduce new technology to meet changing customer requirements and emerging industry standards and requirements. There can be no assurance that Columbus Plastics will successfully complete any such developments. In addition, there can be no assurance that products or technologies developed by others will not render Columbus Plastics' products or technologies non-competitive or obsolete.

20

GOVERNMENT AND ENVIRONMENTAL REGULATION

Columbus Plastics' manufacturing activities are subject to extensive and rigorous government regulation designed to protect the environment. The United States Environmental Protection Agency and comparable state and local regulatory agencies actively enforce environmental regulations, and some of these agencies conduct periodic inspections to determine compliance with government regulations. Failure to comply with applicable regulatory requirements can result in, among other things, fines, suspensions of approvals, seizures or recalls of products, operating restrictions, and criminal prosecutions. Furthermore, changes in existing regulations or adoption of new regulations could impose costly new procedures for compliance with, or prevent Columbus Plastics from obtaining, or affect the timing of, regulatory approvals.

The restrictions imposed by environmental regulations may change from time to time. There can be no assurance that subsequent legislation or administrative changes might not materially adversely affect Columbus Plastics' business and future prospects. See "PROPOSAL NO. 1--APPROVAL OF THE ACQUISITION--Business of Columbus Plastics--Environmental Compliance."

MATERIAL LABOR AGREEMENT

As of October 31, 1995, Columbus Plastics employed a total of 423 employees, 343 of whom are covered by a collective bargaining agreement with the International Association of Machinists and Aerospace Workers ("IAM"), which expires in August 1998. There can be no assurance that work stoppages or slow-downs will not occur in Columbus Plastics operations in connection with the renegotiation of this agreement. Any work stoppage or slow-down experienced by Columbus Plastics, or any of its key customers, Navistar in particular, could have a material adverse effect on Columbus Plastics' results of operations. See "PROPOSAL NO. 1--APPROVAL OF THE ACQUISITION--Business of Columbus Plastics--Employees."

IMPORTANCE OF BUSINESS RELATED TO REDESIGNED MODEL INSTRUCTIONS

Columbus Plastics competes for business during the redesign of certain existing models by its customers. There can be no assurance that Columbus Plastics will be a successful competitor for new business in the future. If Columbus Plastics were to fail to obtain new business for new models or to retain or increase business for redesigned existing models, it could have an adverse effect on Columbus Plastics' results of operations.

UTILIZATION OF THE NET OPERATING LOSSES AND CAPITAL LOSS CARRYFORWARDS

The rules relating to the utilization of NOLs and capital loss carryforwards are complex and can result in a corporation that undergoes a substantial change in its organization and ownership being unable to use such losses or having its ability to utilize such losses severely restricted. The Merger and Acquisition have been structured in a manner intended to avoid the application of such limitations. However, the Company has not requested a ruling from the IRS with respect to either the Merger or the Acquisition and it is possible that the IRS will disagree with the conclusion that the Merger and Acquisition has avoided application of such limitations. If the IRS successfully challenges Core Materials' ability to utilize the existing NOLs and capital loss carryforwards, the federal income tax liability of Core Materials may increase substantially. In addition, such successful challenge could also result in stockholders being required to recognize gain upon their exchange of Common Stock of the Company for the Common Stock of Core Materials. See "PROPOSAL NO. 2--APPROVAL OF THE MERGER--Federal Income Tax Consequences of the Merger and the Acquisition."

Although the Prohibited Transfer Provision to be contained in Core Materials' Certificate of Incorporation is intended to prevent a Change in Control, which would substantially impair Core Materials' ability to use the Company's net operating losses and capital loss carryovers, the Company will not seek a revenue ruling from the IRS with respect to the Prohibited Transfer Provision and there can be no assurance that such provision will be effective.

In addition, the Asset Purchase Agreement provides that a purchase price adjustment after the closing of the Acquisition shall occur in the event that it is necessary to prevent an application of the limitations on the utilization of the NOLs under Section 382 of the Code by reducing the number of shares of Core Materials Common Stock deliverable to Navistar pursuant to the Asset Purchase Agreement and increasing the principal amount of the Secured Note. This adjustment would have the effect of an increase in the purchase

21

price paid to Navistar because the amount by which the Secured Note would increase for each share that is not delivered to Navistar is greater than the per share prices at which the Company Common Stock has traded recently. See "PROPOSAL NO. 1--APPROVAL OF THE ACQUISITION--The Asset Purchase
Agreement--Purchase Price Adjustments--The Adjustment Based on Closing Date Ownership."

RELATIONSHIPS WITH AND RELIANCE ON NAVISTAR

Sales to Navistar (at historical standard cost) constituted approximately 63% and 59% (67% and 63% on a pro forma basis reflecting the provisions of the Comprehensive Supply Agreement) of Columbus Plastics' revenues for fiscal year 1995 and the nine months ended July 31, 1996, respectively. In connection with the Acquisition, Navistar and Core Materials will enter into the Comprehensive Supply Agreement whereby Navistar will agree to purchase, and Core Materials will agree to sell, all of Navistar's Products. See "PROPOSAL NO. 1--APPROVAL OF THE ACQUISITION--Ancillary Agreements--The Supply Agreement." The Comprehensive Supply Agreement will have an initial term of five years from the Closing. If Navistar reasonably demonstrates to Core Materials that a particular Product is no longer a competitive value with respect to price, performance, delivery, reliability, technology and quality with other equivalent products then available, then Core Materials will have sixty (60) days from such demonstration to cure the deficiency. If Core Materials cannot remedy the situation within such sixty (60) days, Navistar may, at its option, terminate the obligations of the parties under the Supply Agreement with respect to the non-competitive Products. In addition, if Core Materials defaults in performing any of its material obligations under the Supply Agreement and such default continues uncured for thirty (30) days after written notice thereof is given by Navistar to Core Materials, then Navistar may terminate the Supply Agreement with respect to the Products materially affected by the default or, if the default materially affects all Products, terminate the Supply Agreement in its entirety. Navistar also may terminate the Supply Agreement with regard to Products if Core Materials does not maintain adequate quality thereof as provided in the Supply Agreement. While Navistar will agree pursuant to the Supply Agreement to purchase all of its requirements of Products from Core Materials, there is no minimum amount of purchases that Navistar is required to make under the contract. There can be no assurance that Core Materials will remain competitive with respect to the Products, that Core Materials will maintain sufficient quality of the Products or that Core Materials may not somehow otherwise fail to perform under or breach the Supply Agreement. In addition, there can be no assurance that Navistar will require the Products to the same extent as it has in the past or that Navistar will place new products with Core Materials in the future. If Core Materials lost any significant portion of its sales to Navistar, it would have a material adverse effect on the business, financial condition and results of operations of Core Materials.

In addition, pursuant to the Transitional Services Agreement, after the Acquisition Navistar will provide several key services to Core Materials. See "PROPOSAL NO. 1--APPROVAL OF THE ACQUISITION--Ancillary Agreements--The Transitional Services Agreement." These services consist primarily of internal financial reporting, accounting, budgeting and tax planning and return preparation services and computer services. Although Core Materials plans to develop its own services to allow the transition from Navistar's services, there can be no assurance that Core Materials will be able to develop these operations in a timely or cost-effective manner.

DEPENDENCE ON MAJOR CUSTOMERS

Columbus Plastics derived approximately 63% and 59% (67% and 63% on a pro forma basis reflecting the provisions of the Comprehensive Supply Agreement) of its revenues from sales to Navistar in fiscal 1995 and the nine months ended July 31, 1996, respectively. The medium and heavy truck industry, the market in which Navistar competes, is highly competitive, is subject to cycles in the overall business environment, and is particularly sensitive to the industrial sector which generates a significant portion of the freight tonnage hauled. Government regulations have impacted and will continue to impact specifications of equipment as well as trucking operations and efficiency.

In addition, Columbus Plastics derived approximately 34% and 39% of its revenues from sales (31% and 35% on a pro forma basis assuming Navistar revenues reflect the provisions of the Comprehensive Supply Agreement) to Yamaha in fiscal 1995 and the nine months ended July 31, 1996, respectively. Demand for Yamaha products is related to the level of general economic activity, among other factors, and specifically to

22

the cyclycality of the personal watercraft industry. Columbus Plastics has no written purchase agreement with Yamaha covering the components produced for Yamaha. Therefore, there is no assurance that Yamaha will continue to purchase Columbus Plastics products at the same levels as in previous years or that such relationship will continue in the future.

There can be no assurance that Core Materials will maintain or improve Columbus Plastics' relationship with Navistar or Yamaha or that Core Materials will continue to supply these customers at current levels. The loss of a significant portion of sales to Navistar or Yamaha would have a material adverse effect on the business, financial condition and results of operations of Core Materials.

NO PUBLIC MARKET VALUATION OF COLUMBUS PLASTICS

Columbus Plastics has no publicly-traded securities. As a result, no public market valuations of Columbus Plastics were available to the Company and its financial advisor, Nomura Securities International, Inc. ("Nomura"), for purposes of evaluating the transactions contemplated under the Asset Purchase Agreement. In rendering its fairness opinion to the Company, Nomura made numerous assumptions for purposes of valuing Columbus Plastics; such valuation is not necessarily indicative of the actual value of Columbus Plastics. Nomura rendered its fairness opinion to the Company's Board of Directors on the date of the Asset Purchase Agreement and restated its opinion on the date of this Proxy Statement/Prospectus. See "PROPOSAL NO. 1--APPROVAL OF THE ACQUISITION--Opinion of Nomura."

CONTROL BY NAVISTAR; ANTI-TAKEOVER EFFECTS

In accordance with the terms of the Asset Purchase Agreement, from and after the Closing Date and until the first annual meeting of the stockholders of Core Materials following the Closing Date, Core Materials' Board of Directors shall be comprised of two representatives to be designated by Navistar (the "Navistar Directors"); two representatives to be designated by members of the Company's existing Board of Directors (the "Company Directors"); and one representative to be mutually satisfactory to Navistar and the Company (the "Independent Director"). See "PROPOSAL NO. 1--APPROVAL OF THE ACQUISITION--Management of Core Materials After the Acquisition." In addition, pursuant to the terms of the Asset Purchase Agreement, Navistar will receive in the Stock Issuance 4,264,000 shares of Core Materials Common Stock, representing approximately 45% of the total number of shares of Core Materials Common Stock issued and outstanding on a fully diluted basis after giving effect to the Acquisition. As a result, Navistar will have the power to significantly influence the composition of Core Materials' Board of Directors and to approve actions requiring stockholder approval, including (i) amendments to Core Materials' Certificate of Incorporation and By-laws and (ii) mergers or sales of all or substantially all of the assets of Core Materials. Furthermore, by virtue of the provision in Core Materials' Certificate of Incorporation that requires the affirmative vote of the holders of at least 66 2/3% of the then outstanding shares of Capital Stock of Core Materials entitled to vote generally in the election of directors to approve certain transactions (including mergers and the sale, lease or exchange of substantially all of Core Materials' assets) Navistar will have the ability to preclude any such transaction regardless of the vote of the other stockholders. In addition, in the Asset Purchase Agreement, the Company has agreed that until March 31, 1997 it will not take certain actions without the prior written consent of Navistar. See "PROPOSAL NO. 1--APPROVAL OF THE ACQUISITION--The Asset Purchase Agreement--Representations and Warranties; Conditions to Closing; Amendments; Termination."

Furthermore, certain provisions of Core Materials' charter documents may have the effect of deterring a takeover of Core Materials. These provisions include (i) a requirement that 66 2/3% of the outstanding shares of capital stock entitled to vote generally in the election of directors ("Voting Stock") approve certain mergers, sales of assets or other transactions; (ii) limitations on stockholder action by written consent without a meeting and a minimum ownership requirement for stockholders to call special meetings of stockholders of at least 20%; and (iii) the imposition of a supermajority voting requirement to approve any amendment to certain provisions of Core Materials' Certificate of Incorporation.

Additionally, the Prohibited Transfer Provision (as defined herein under "PROPOSAL NO. 2-- APPROVAL OF THE MERGER--Description of Core Materials Capital Stock--Restrictions on Transfer") to be contained in Core Materials' Certificate of Incorporation generally would prohibit transfers of Core Materials Common Stock under circumstances which would cause a person to hold a Prohibited Ownership

23

Percentage or would increase the ownership percentage of a person who has held a Prohibited Ownership Percentage within three years prior to the proposed transfer. The "Prohibited Ownership Percentage" is defined by reference to complex federal tax laws and regulations, but generally means ownership of 4.5% or more (based on value) of Core Materials' capital stock. The Prohibited Transfer Provision generally would preclude the acquisition of Core Materials Common Stock by a person who would hold a Prohibited Ownership Percentage and would require the immediate sale of shares purported to have been acquired by such person. The restriction would not prohibit the granting of proxies to Core Materials management or others. The objective in seeking to impose the Prohibited Transfer Provision is to avoid an "ownership change" for federal income tax purposes, which could severely limit Core Materials' ability to use its substantial NOLs. Although not intended, the Prohibited Transfer Provision may adversely affect the marketability of the Core Materials Common Stock by discouraging potential investors from acquiring stock of Core Materials, and could have the effect of impeding an attempt to acquire a significant or controlling interest in Core Materials, even though such attempt may be beneficial to Core Materials and its stockholders. See "PROPOSAL NO. 2--APPROVAL OF THE MERGER--Description of Core Materials Capital Stock."

Core Materials is governed by the provisions of Section 203 of the Delaware General Corporation Law, which prohibits a publicly held Delaware corporation from engaging in a "business combination" with an "interested stockholder" for a period of three years following the time that such stockholder became an interested stockholder, unless (i) prior to such time either the business combination or the transaction which resulted in the stockholder becoming an interested stockholder is approved by the board of directors of the corporation,
(ii) upon consummation of the transaction which resulted in the stockholder becoming an interested stockholder, the interested stockholder owns at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced (other than certain excluded shares) or (iii) on or after such time the business combination is approved by the board and authorized at an annual or special meeting of stockholders, and not by written consent, by the affirmative vote of at least 66 2/3% of the outstanding voting stock which is not owned by the interested stockholder. A "business combination" includes certain mergers, consolidations, asset sales, transfers and other transactions resulting in an increase in the percentage of any class or series of stock owned by the interested stockholder or in a financial benefit to the stockholder. An "interested stockholder" is a person who, together with affiliates and associates, owns (or, in certain cases, within three years, did own) 15% or more of the corporation's voting stock.

While the provisions of Delaware law and Core Materials' Certificate of Incorporation and By-laws described above may have certain antitakeover effects, the primary impediment to a potential acquiror's attempt to acquire a controlling interest in Core Materials will be that at least initially after the Acquisition Navistar will own approximately 45% of the Voting Stock of Core Materials on a fully diluted basis thereby making Core Materials an unlikely takeover target.

NEED TO ATTRACT AND RETAIN KEY PERSONNEL

The success of Core Materials will be dependent, in part, upon its ability to hire and retain key management personnel. The Company is currently seeking to hire a chief executive officer and a chief financial officer for Core Materials. Until suitable candidates are hired for these management positions, the current plant manager of Columbus Plastics will oversee the day-to-day operations of Columbus Plastics under the supervision of the Board of Directors. There can be no assurance that Core Materials will be successful in attracting and retaining qualified managerial personnel sufficient to meet its requirements.

NO DIVIDENDS

Core Materials is a new entity and has never paid cash dividends on its Common Stock. Core Materials currently intends to retain earnings to finance the growth and development of its business and does not anticipate paying cash dividends in the foreseeable future. Moreover, Core Materials will be prohibited from paying dividends on its Common Stock by covenants contained in the Secured Note. See "PROPOSAL NO. 1--APPROVAL OF THE ACQUISITION--Management's Discussion and Analysis of Results of Operations and Financial Condition of Columbus Plastics--Liquidity and Capital Resources" and "--Ancillary Agreements--The Secured Note--Covenants--Negative Covenants."

The rights of holders of Company Common Stock are presently governed by Maryland law and the Company's Articles of Incorporation and By-laws. Upon consummation of the Merger, each share of Company Common Stock will be converted into one share of Core Materials Common Stock and the rights of the holders thereof will be governed by Delaware corporation law and Core Materials' Certificate of Incorporation and By-laws.

Material differences between the rights of stockholders of the Company and Core Materials include the following: (i) Maryland law provides stockholders with more limited rights of inspection than does Delaware law; (ii) the By-laws of the Company require that a majority of the Company's Board of Directors be unaffiliated directors, whereas Core Materials' By-laws do not; (iii) Maryland law provides that any director or officer may be removed with or without cause by the affirmative vote of a majority of all the votes entitled to be cast in the election of directors, unless the Charter of the corporation provides otherwise, which the Articles of Incorporation of the Company does not, whereas the Certificate of Incorporation and By-laws of Core Materials provide that a director may be removed with or without cause by the holders of at least 80% of the voting power of the outstanding shares of capital stock of Core Materials entitled to vote generally in the election of directors; (iv) as permitted by Maryland law, the Company's Articles of Incorporation limit the liability of officers to the corporation or its stockholders for money damages to the same extent as directors, whereas under Delaware law the liability of officers may not be limited; (v) the By-laws of the Company contain a limitation on the ability of the Company to incur indebtedness, whereas the By-laws of Core Materials do not contain a provision restricting the incurrence of indebtedness;
(vi) the Articles of Incorporation of the Company contain provisions restricting the transfer of shares of Company Common Stock in order to preserve the Company's status as a REIT, whereas Core Materials' Certificate of Incorporation does not contain a similar provision; (vii) Core Materials' Certificate of Incorporation contains provisions prohibiting certain transfers of Core Materials Common Stock intended to preserve Core Materials' NOLs, whereas the Company's Articles of Incorporation does not contain a similar provision; (vii) Core Materials' Certificate of Incorporation contains provisions prohibiting certain transfers of Core Materials Common Stock intended to preserve the corporation's net operating loss carryovers, whereas the Company's Articles of Incorporation does not contain a similar provision; (viii) Core Materials will be subject to Delaware's annual franchise tax (which under current law will be approximately $34,800 per year), while the Company is not subject to any similar tax in Maryland; (ix) under Maryland law, the exclusive power to change the by-laws may be left with the stockholders, vested in the directors or shared by both groups, while under Delaware law, the power to change the By-laws belongs to the stockholders and, although it may be shared with directors, the stockholders may never be divested of this power; (x) Maryland law permits the charter of a corporation to deny all voting rights to shares of any class of stock, while Delaware law prohibits denying voting rights to shares of a class in connection with an amendment to the certificate of incorporation if the amendment would change the par value of the class or would adversely affect the powers, preferences of special rights of the class; and (xi) in connection with the voluntary dissolution of the corporation, Maryland law requires the approval of stockholders by the affirmative vote of two-thirds of all the votes entitled to be cast on the matter, while Delaware law requires the approval of stockholders by the affirmative vote of a majority of the votes entitled to be cast on the matter. The material similarities and differences between Maryland corporation law and the Company's Articles of Incorporation and By-laws, on the one hand, and Delaware corporation law and the Core Materials Certificate of Incorporation and By-laws, on the other, which should be considered in connection with the Merger, are summarized in "PROPOSAL NO. 2-- APPROVAL OF THE MERGER."

SHARES ELIGIBLE FOR FUTURE SALE BY NAVISTAR

The shares of Core Materials Common Stock which Navistar will receive under the Asset Purchase Agreement may not be sold in the absence of registration under the Securities Act or an exemption therefrom, including the exemptions contained in Rule 145 under the Securities Act. However, at the Closing, Core Materials will enter into a Registration Rights Agreement with Navistar pursuant to which Navistar and its transferees will have rights to demand registration of the resale of such shares of Core Materials Common Stock at any time after the date of the Closing. Navistar will also be granted unlimited piggyback registration

25

rights with respect to these shares under the Registration Rights Agreement. See "PROPOSAL NO. 1-- APPROVAL OF THE ACQUISITION--Ancillary Agreements--The Registration Rights Agreement." No prediction can be made as to the effect, if any, of future sales of shares of Core Materials Common Stock by Navistar, if any, on the market price of the Core Materials Common Stock prevailing from time to time. Sales of substantial amounts of Core Materials Common Stock by Navistar, or the perception that such sales could occur, could adversely affect prevailing market prices for those securities.

NO ASSURANCE AS TO MARKET PRICE.

Because there has been no prior market for the Core Materials Common Stock, there can be no assurance as to its market price following the Merger and the Acquisition. Moreover, there can be no assurance that the market value of the Core Materials Common Stock held by a stockholder will equal or exceed the market value of the Company Common Stock held by such stockholder prior to the Merger and the Acquisition. While Core Materials intends to list the Core Materials Common Stock on the American Stock Exchange, there can be no assurance that the shares will be so listed or as to the development or liquidity of any market for the Core Materials Common Stock. See "SUMMARY--Historical Market Price and Dividend Data."

NO APPRAISAL RIGHTS

Holders of RYMAC Common Stock will have no appraisal rights under Maryland law in connection with or as a result of the matters to be acted upon at the Special Meeting. See "PROPOSAL NO. 2-- APPROVAL OF THE MERGER--No Dissenters' Rights of Appraisal."

INTRODUCTION

DATE, TIME AND PLACE

A Special Meeting will be held on December 19, 1996 at 10:00 a.m., Eastern time, at the American Stock Exchange, 86 Trinity Place, New York, New York 10006-1881.

MATTERS TO BE CONSIDERED AT THE SPECIAL MEETING

At the Special Meeting, holders of shares of Company Common Stock will consider and vote upon proposals (i) to approve and adopt the terms and conditions of the Asset Purchase Agreement including the Stock Issuance, (ii) contingent on the approval of the Asset Purchase Agreement, to approve and adopt the Merger Agreement and (iii) such other matters as may properly be brought before the Special Meeting.

26

RECORD DATE; SHARES ENTITLED TO VOTE

The Board of Directors has fixed November 4, 1996 as the record date for the determination of stockholders entitled to notice of and to vote at the Special Meeting (the "Record Date"). Accordingly, only holders of record of shares of Company Common Stock on the Record Date will be entitled to notice of and to vote at the Special Meeting. As of the Record Date, there were 5,210,600 shares of Company Common Stock outstanding, held by approximately 431 holders of record. Each holder of record of shares of Company Common Stock on the Record Date is entitled to cast one vote per share.

Directors and executive officers of the Company and their affiliates who beneficially owned approximately 1.7% of the outstanding shares of Company Common Stock as of the Record Date have advised the Company that they presently intend to vote or direct the vote of all shares of Company Common Stock over which such persons have voting control FOR approval and adoption of the Merger Agreement.

As of the Record Date, neither Navistar nor any of its subsidiaries owned any outstanding shares of Company Common Stock.

QUORUM AND VOTING OF PROXIES

The presence, in person or by proxy, of a majority of the outstanding shares of Company Common Stock is necessary to constitute a quorum at the Special Meeting. Stockholders voting or abstaining from voting on any issue will be counted as present for purposes of constituting a quorum. If a quorum is present, the affirmative vote of the holders of a majority of the votes cast at the Special Meeting is required to approve the Asset Purchase Agreement. The affirmative vote of the holders of two-thirds of the outstanding shares of Company Common Stock entitled to vote at the Special Meeting is required to approve the Merger Agreement. Under the rules of the American Stock Exchange, brokers who hold shares in street name for customers will not have authority to vote such shares on the proposal to approve the proposals described herein unless they have received written instructions from beneficial owners. Abstentions will have the effect of a vote against each of the proposals. To the extent a quorum is otherwise present at the Special Meeting, shares not present and, therefore, not voted on the Acquisition proposal (including broker non-votes) will have no effect on the approval of the Asset Purchase Agreement. However, shares not voted on the Merger proposal will have the same effect as votes against the proposal.

All shares of Company Common Stock which are entitled to vote and are represented at the Special Meeting by properly executed proxies received prior to or at the Special Meeting, and not revoked, will be voted at the Special Meeting in accordance with the instructions indicated on such proxies. IF NO INSTRUCTIONS ARE INDICATED, SUCH PROXIES WILL BE VOTED FOR APPROVAL AND ADOPTION OF THE PROPOSALS DESCRIBED HEREIN. The Board of Directors of the Company knows of no matters to be presented at the Special Meeting other than those described in this Proxy Statement/Prospectus. If any other matters are properly presented at the Special Meeting for consideration, including, among other things, consideration of a motion to adjourn the Special Meeting to another time and/or place (including, without limitation, for the purpose of soliciting additional proxies), the persons named in the enclosed form of proxies and acting thereunder will have discretion to vote on such matters in accordance with their best judgment. The By-laws of the Company provide that the Special Meeting may be adjourned by the Company from time to time without notice to a date not more than one hundred twenty days after the Record Date.

Any proxy given pursuant to this solicitation may be revoked by the person giving it at any time before it is voted. Proxies may be revoked by (i) filing with the Secretary of the Company at or before the taking of the vote at the Special Meeting, a written notice of revocation bearing a later date than the proxy, (ii) duly executing a later dated proxy relating to the same shares and delivering it to the Secretary of the Company before the taking of the vote at the Special Meeting or (iii) attending the Special Meeting and voting in person (although attendance at the Special Meeting will not in and of itself constitute a revocation of a proxy). Any written notice of revocation or subsequent proxy should be sent to the Company c/o American Stock Transfer & Trust Co., 40 Wall Street, New York, New York 10005, Attention: Ms. Paula Magno, or hand delivered to the Secretary of the Company at Penn Center West II, Suite 311, Pittsburgh, Pennsylvania 15276, Attention: Secretary, so as to be delivered at or before the taking of the vote at the Special Meeting.

27

All expenses of this solicitation, including the cost of preparing and mailing of this Proxy Statement/ Prospectus, will be borne by the Company. In addition to solicitation by use of the mails, proxies may be solicited by directors, officers and employees of the Company in person or by telephone, telegram or other means of communication. Such directors, officers and employees will not be additionally compensated, but may be reimbursed for reasonable out-of-pocket expenses in connection with such solicitation. The Company has retained Corporate Investor Communications, Inc., at an estimated cost of $4,500, plus reimbursement of expenses, to assist in its solicitation of proxies from brokers, nominees, institutions and individuals. Additionally, the Company's stock transfer agent, American Stock Transfer & Trust Co., New York, New York will conduct proxy solicitations on the Company's behalf and receive reimbursement for reasonable out-of-pocket expenses. Arrangements will also be made with brokerage firms and other custodians, nominees and fiduciaries for the forwarding of proxy solicitation material to certain beneficial owners of the Company Common Stock and the Company will reimburse such brokerage firms, custodians, nominees and fiduciaries for reasonable out-of-pocket expenses incurred by them in connection therewith. The expenses of the proxy solicitation will be paid by the Company.

PROPOSAL NO. 1--APPROVAL OF THE ACQUISITION

Stockholders of the Company are being asked to approve the Asset Purchase Agreement and the consummation of the transactions contemplated thereby, including the Acquisition and the Stock Issuance. If the Asset Purchase Agreement is not approved by the stockholders at the Special Meeting, the Acquisition will not be consummated and Proposal No. 2 will not be acted upon. If the Asset Purchase Agreement is approved by the Company's stockholders but the Merger does not receive the requisite stockholder approval, the Acquisition will be consummated only if Navistar agrees to waive the relevant conditions in the Asset Purchase Agreement.

REASONS FOR AND BACKGROUND OF THE ACQUISITION

As a result of the earnings difficulties and the substantial diminution in value of the mortgage assets of the Company experienced since the second quarter of 1992, the Company's Board of Directors determined in mid-1994 that the Company would not pursue its historical line of business and would investigate alternative opportunities to maximize stockholder value.

The Board of Directors determined that management should focus its efforts on acquisition candidates that satisfied, among other things, the following criteria: the candidate would be privately held and seeking access to the public capital markets; the candidate would be operating in an industry in which the candidate had growth potential; and the candidate should be one already generating sufficient income that would render the Company's existing NOLs attractive.

During the summer of 1995, management held discussions with the owners of an acquisition candidate in the retail sporting goods industry with the assistance of Hellmold Associates, Inc. ("Hellmold"), which had been retained by the Company on June 26, 1995 to assist the Company in a possible transaction involving this candidate. By late October, 1995, the Company's management and the owners of such acquisition candidate had been unable to reach an agreement on the terms of such transaction, and negotiations were abandoned.

On November 1, 1995, the Company expanded the scope of Hellmold's engagement to identifying and contacting potential acquisition candidates and assisting the Company in structuring and negotiating a strategic transaction. Hellmold had previously been retained by Navistar in May 1995 to assist it in selling its Columbus Plastics Operations. See "Interests of Certain Persons in the Transactions." In addition, on November 28, 1995, the Board of Directors appointed a committee consisting of Messrs. Richard Conte and Malcolm Prine to assume primary responsibility for evaluating, structuring and negotiating an acquisition transaction involving the Company (the "Committee").

During the period from October 1995 through February 1996, Hellmold contacted approximately 70 companies that owned prospective acquisition candidates to solicit indications of interest in a possible business combination with the Company. Of these initial contacts, 51 companies requested further information concerning the Company and possible transaction structures. The Committee, together with Hellmold,

28

evaluated 18 potential transactions and eventually concluded that Columbus Plastics constituted the most attractive candidate identified in the search process, based in large part on the Committee's assessment that Columbus Plastics revenues (on a pro forma basis to give effect to market pricing of its products) and earnings potential were substantially larger than any alternative candidate, thereby allowing significant current utilization of the Company's NOLs, and the projected growth prospects for the Sheet Molding Composite industry in which Columbus Plastics operates.

On January 8, 1996, based on a descriptive memorandum of Columbus Plastics supplied by Navistar, the Company submitted a preliminary indication of interest of approximately $60 million, which purchase price would be paid through a note and approximately 4.3 million shares of stock (based on a stipulated stock price of $2.50 per share).

On January 15, 1996, Hellmold advised the Company that it was one of three bidders (from among the bids received) that Navistar would allow to perform detailed due diligence on Columbus Plastics. Commencing shortly thereafter, the Company commenced a detailed due diligence review of Columbus Plastics.

On February 16, 1996, the Company engaged Nomura to render an opinion with respect to the fairness, from a financial point of view, to the Company's stockholders of the consideration to be paid in the Acquisition.

On February 23, 1996, Messrs. Conte and Prine, along with representatives of Nomura, visited the Columbus Plastics facility in Columbus, Ohio, as part of the Company's due diligence review of Columbus Plastics. In addition, Messrs. Prine and Conte spoke with Mr. Thomas M. Hough, Treasurer of Navistar, to discuss the terms of the proposed combination between the Company and Columbus Plastics. Based on these discussions and the preliminary results of the Committee's due diligence review, the Company submitted a written proposal to Navistar on March 22, 1996, pursuant to which it proposed a transaction in which it would acquire the assets and assume substantially all of the associated liabilities of Navistar's Columbus Plastics division in exchange for 4,264,000 shares of Common Stock and a note of the Company in the principal amount of $50,000,000 (the "Initial Terms").

On May 14, 1996, the Company and Navistar entered into a non-binding letter of intent contemplating an acquisition of Columbus Plastics in a transaction based on the Initial Terms. During the latter part of May and throughout June 1996, representatives of the Company, Navistar and their legal counsel were engaged in negotiating the definitive documentation for the transaction set forth in the May 14 letter of intent.

On June 4, 1996, Mr. Hough contacted Mr. Conte by telephone and advised him that the operating results of Columbus Plastics for the first half of its fiscal year 1996 were below the projections previously supplied to the Company by Navistar and upon which the Company had submitted its proposal incorporating the Initial Terms. On July 5, 1996, in a meeting with various Navistar personnel, Mr. Prine was informed that the most recent projections that Navistar had prepared for Columbus Plastics were substantially below the projections previously supplied to the Company by Navistar. Further negotiations on the definitive terms of a transaction were suspended at such time and were not resumed until August 13, 1996, when Messrs. Prine and Conte and Mr. Ralph O. Hellmold, the President of Hellmold Associates Inc., met with Mr. Hough and Mr. Thomas E. Rigsby, Vice President--Truck Manufacturing of Navistar. At this meeting, Messrs. Prine and Conte discussed the willingness of the Company to proceed with a transaction at a reduced purchase price. Navistar and the Company agreed that the Initial Terms would be revised as follows: (i) 4,264,000 shares of Common Stock; (ii) a note of the Company in the principal amount of $25,504,000; (iii) a contingent increase in the principal amount of such note such that if (A) the Company's earnings before interest and taxes ("EBIT") for the Company's fiscal year ended December 31, 1997 exceeded $6,512,000 ("Forecasted EBIT"), the principal amount of the note would be increased by an amount equal to the product of (x) the excess amount ("1997 Excess EBIT") and
(y) 5.55; (B) if the Company's EBIT for fiscal year ended December 31, 1998 exceeds Forecasted EBIT, the principal amount of the note would be increased by an amount equal to the product of (x) the excess amount ("1998 Excess EBIT") less the 1997 Excess EBIT and (y) 4.50; and (C) if the Company's EBIT for the Company's fiscal year ended December 31, 1999 exceeds the Forecasted EBIT, the principal amount of the note would be increased by an amount equal to the product of (x) the excess amount less the 1998 Excess EBIT and (y) 2.75; provided, that the total amount by which the principal amount of the note may be increased pursuant to such contingent increases shall not exceed

29

$24,496,000 in the aggregate; and (iv) a further contingent increase in the note in the event certain events described under "-- The Asset Purchase Agreement--Purchase Price Adjustments--The Adjustment Based on Closing Date Ownership" occur that would result in Navistar retroactively reducing the number of shares of Common Stock it receives at the Closing in order to preserve intact the ability of the Company to utilize its NOLs, the specific terms of such reduction remaining at that time the subject of further negotiations.

On August 30, 1996, after further discussion among the Company, Navistar and their respective counsel with respect to the purchase price adjustment referred to in clause (iv) above as well as alternative resolutions of the issue of preserving the Company's NOLs, the Company and Navistar agreed that if the events described under "-- The Asset Purchase Agreement--Purchase Price Adjustments--The Adjustment Based on Closing Date Ownership" were to occur and thereby give rise to a retroactive reduction in the number of shares of Common Stock Navistar receives at the Closing, the $25,504,000 principal amount of the Company's note shall be increased by an amount equal to the sum of (x) to the extent that Navistar's ownership of Common Stock effective as of the Closing, would, on account of the reduction caused by such event, be reduced below 40% of the total shares of Common Stock of the Company issued and outstanding as of the effective time of the Closing, the product derived by multiplying $7.50 times the total number of Excess Shares (as defined below) that, if retained by Navistar, would cause Navistar's ownership of Common Stock effective as of the Closing to equal 40% of the total shares of Common Stock of the Company issued and outstanding as of the effective time of Closing plus (y) the product derived by multiplying the total number of all remaining Excess Shares times $5.00, and the number of shares of Common Stock deliverable to Navistar shall be reduced by such number of shares (the "Excess Shares") such that the number of shares then deliverable to Navistar would be one share short of causing an event triggering a restriction on the Company's ability to use its NOLs (the "NOL Adjustment Provision").

On September 6, 1996, the Board of Directors of the Company held a special meeting in Pittsburgh, Pennsylvania at which all members other than Mr. Walker were present, together with Hellmold, Nomura, and the Company's counsel. At such meeting, Messrs. Conte and Hellmold, Nomura and the Company's legal counsel made presentations to the Board of Directors concerning the proposed transaction, and Nomura delivered its oral opinion to the effect that as of such date the purchase price to be paid to Navistar for the Columbus Plastics division, based on specified assumptions which did not give effect to the NOL Adjustment Provision in the Asset Purchase Agreement, was fair to the Company's stockholders from a financial point of view. After representatives of Hellmold and Nomura were excused from the meeting, the Board deliberated over the proposed transaction and resolved that, subject to receiving final forms of definitive documentation to reflect the terms of the transaction as reviewed and discussed at the meeting on or prior to 5:00 p.m. September 13, 1996, it was the sense of the Board that they would reconvene to approve the transactions on or prior to such date.

On September 12, 1996, the Board of Directors convened a special meeting telephonically with all members present other than Mr. Walker, together with a representative of Nomura and the Company's legal counsel. During such meeting, Mr. Conte confirmed that documentation had been finalized consistent with the Board's understanding and a representative of Nomura confirmed its oral opinion delivered at the Board meeting of September 6th. The Board of Directors then approved, on the unanimous vote of those members present via telephone, the Asset Purchase Agreement, certain ancillary agreements and the transactions contemplated thereby, including the Merger.

RECOMMENDATION OF THE BOARD OF DIRECTORS

The Board of Directors believes that the terms of the Asset Acquisition Agreement and the transactions contemplated thereby are fair to and in the best interests of the Company and its stockholders. Accordingly, at a special meeting held on September 12, 1996, the Board of Directors, by the unanimous vote of all directors present, approved the Asset Acquisition Agreement and the transactions contemplated thereby and determined to recommend that the stockholders of the Company approve the Asset Purchase Agreement and the consummation of the transactions contemplated thereby, including the Stock Issuance and the Merger.

30

In determining to recommend the approval of the Asset Purchase Agreement and the consummation of the transactions contemplated thereby, including the Stock Issuance and the approval and adoption of the Merger, to the Company's stockholders, the Board considered a number of factors, including the following:

i. the desirability of diversifying into commercial areas beyond those in which the Company has historically operated, which the Board anticipates will provide the Company's stockholders with the opportunity to participate in any potential future growth of a company which has significantly greater business and financial resources, prospects and a larger market capitalization than the Company were it to pursue the development of a new line of business using only its existing resources in lieu of the Acquisition;

ii. the Company's current potential for future cash flow and earnings absent consummation of the Acquisition;

iii. the terms of the consideration to be paid by the Company under the Asset Acquisition Agreement, and in particular the willingness of Navistar to accept payment of the consideration necessary to consummate the Acquisition partially in the form of the Secured Note and the Contingent Earn-Out (as described below under--The Asset Purchase Agreement--Purchase Price Adjustments--Contingent Earn-Out), thereby allowing the Company to acquire a business having revenues and profits in the order of magnitude of that of Columbus Plastics;

iv. the Board's favorable view of the prospects of the sheet molding composite fiberglass parts industry;

v. the Company's historical results of operations, cash flows and financial condition;

vi. historical data relating to the market prices and trading volumes of the Company's Common Stock;

vii. the valuation analyses of Nomura presented to the Board of Directors at a meeting held on September 6, 1996;

viii. the opinion of Nomura as to the fairness to the Company's stockholders, from a financial point of view, of the consideration to be paid by the Company under the Asset Purchase Agreement;

ix. the extraordinarily low likelihood of entering into a transaction with a third party having more favorable terms than those of the Acquisition, in particular, after considering the efforts of Hellmold in soliciting indications of interest from third parties and the results of such efforts;

x. the fact that the transaction is intended to qualify as a tax-free reorganization to Company stockholders for federal income tax purposes; and

xi. with respect to the Merger, by reincorporating in Delaware, the Company will be able to benefit from Delaware's comprehensive and well developed corporate laws.

The Board also considered certain potentially negative factors in its deliberations concerning the Acquisition, including:

i. the risk that the anticipated benefits of the Acquisition may not be realized;

ii. the fact that effective voting control in the Company would reside with Navistar after the Acquisition, as a result of which Navistar will control the direction of the business affairs of the Company and public stockholders will not have sufficient voting power to approve any potential future strategic offer for the Company by a third party that might be attractive to such stockholders;

iii. the risk of a significant increase in the purchase price that would result in the event that Navistar were to receive an increase in the principal amount of the Secured Note in exchange for a reduction of the number of shares to be received by Navistar in the Acquisition in the event that the NOL Adjustment Provision were triggered; and

31

iv. the fact that a suitable candidate having the requisite experience in Columbus Plastics' industry to serve as chief executive officer of the Company after consummation of the Acquisition has not yet been identified and retained.

The Board did not undertake a separate analysis of each of these factors nor did the Board reach a separate conclusion with respect to each such factor in its determination of the fairness of the terms of the Acquisition. In view of the above, and the variety of factors, both positive and negative, considered by the Board in reaching its conclusion as to the fairness of the Acquisition, the Board did not find it practicable to and did not quantify or otherwise assign relative weights to the specific factors considered in reaching their respective determination as to the fairness of the terms of the Acquisition. However, as a general matter, the Board believed that the positive factors heretofore described supported its decision to approve the Acquisition and outweighed the potentially negative factors described above.

BASED ON THE FOREGOING, THE BOARD OF DIRECTORS RECOMMENDS THAT STOCKHOLDERS VOTE FOR APPROVAL OF THE ASSET PURCHASE AGREEMENT AND THE CONSUMMATION OF THE TRANSACTIONS CONTEMPLATED THEREBY, INCLUDING THE STOCK ISSUANCE AND THE MERGER.

OPINION OF NOMURA

On September 6, 1996 Nomura delivered its preliminary oral opinion to the Company's Board of Directors to the effect that, as of such date, the consideration to be paid to Navistar by the Company, based on specified assumptions which did not give effect to Section 1(g)(iii) of the Asset Purchase Agreement (which Section is referred to elsewhere herein by the Company as the NOL Adjustment Provision), is fair to the stockholders of the Company from a financial point of view. Nomura confirmed its preliminary oral opinion to the Company's Board of Directors via a telephonic meeting on September 12, 1996. Nomura confirmed its September 12, 1996 oral opinion by delivering its written opinion to the Company's Board of Directors, dated the date of this Proxy Statement/Prospectus, that, as of such date, the consideration to be paid to Navistar by the Company, based on specified assumptions which did not give effect to Section 1(g)(iii) of the Asset Purchase Agreement (which Section is referred to elsewhere herein by the Company as the NOL Adjustment Provision), is fair to the stockholders of the Company from a financial point of view.

A copy of Nomura's written opinion, which sets forth assumptions made, general procedures followed, matters considered and limitation on the review undertaken in connection with the opinion, is attached as Annex II hereto and incorporated herein by reference. Stockholders of the Company are urged to read such opinion in its entirety. The following summary is not intended to be complete and is qualified in its entirety by reference to such opinion.

In arriving at its opinion, Nomura, among other things: (i) reviewed the Asset Purchase Agreement and the Registration Statement; (ii) reviewed certain historical financial statements of the Company and Columbus Plastics and certain projected financial information of the Company and Columbus Plastics provided, respectively, by the managements of the Company and Navistar, and reviewed certain additional operating and financial information relating to the past and current operations and financial condition, as well as the future prospects, of Columbus Plastics provided to it by the management of the Company; (iii) met with certain members of the management of the Company to discuss certain historical financial statements and projected financial information of the Company; (iv) met with certain members of the management of Navistar to discuss certain historical financial statements and projected financial information, and certain additional operating and financial information relating to the past and current operations and financial conditions, as well as the future prospects, of Columbus Plastics; (v) reviewed certain pro forma combined projected financial information for the Company, after giving effect to the Acquisition, prepared by the management of the Company, and met with certain members of the management of the Company to discuss such projected financial information; (vi) reviewed the historical prices and trading volumes of the Company Common Stock; (vii) reviewed certain publicly available financial data and stock market data of companies which it deemed generally comparable to Columbus Plastics; (viii) reviewed the publicly available terms of certain recent acquisitions of companies and businesses which it deemed generally comparable to Columbus Plastics; and (ix) reviewed such other information and conducted such other studies, analyses, inquiries and investigations as it deemed appropriate.

32

In the course of its analysis, Nomura relied upon and assumed without independent verification the accuracy and completeness of all information that was publicly available and the operating, financial and other information provided to them by or on behalf of the Company or Navistar or otherwise reviewed by them, and that all such information was not misleading, and Nomura did not assume any responsibility or liability therefor. With respect to the projected financial information provided to Nomura, Nomura assumed that it was reasonably prepared on bases reflecting best currently available estimates and judgments of the Company's and Navistar's management as to the expected future results of operations, financial condition, prospectus and performance of the Company and Columbus Plastics. Nomura further relied upon the assurances of the Company's and Navistar's management that they were unaware of any facts that would make the projected financial information or other information provided to us inaccurate, incomplete or misleading. Nomura did not perform or obtain any appraisals of the assets or liabilities of Columbus Plastics. In arriving at its opinion, Nomura used such valuation methodologies as it deemed necessary or relevant. Nomura's opinion was necessarily based on economic, market and other conditions, and the information made available to it, as of the date thereof.

The manner in which Nomura calculated the purchase price for the purposes of its opinion did not give effect to Section 1(g)(iii) of the Asset Purchase Agreement described in this Proxy Statement/Prospectus under "--The Asset Purchase Agreement--Purchase Price Adjustments--The Adjustment Based on Closing Date Ownership", which provisions could increase the amount of consideration to be paid to Navistar. Nomura's opinion was limited solely to the purchase price calculated as provided in its written opinion, and Nomura expressed no opinion with respect to the consideration that may actually be paid by the Company in the Acquisition as a result of the adjustment that may result from Section 1(g)(iii) of the Asset Purchase Agreement.

The following is a summary of the material analyses performed by Nomura in connection with its opinion:

Transaction Analysis. Assuming a value per share of Company Common Stock issued in the Acquisition of $2.50, the issuance of the Secured Note to Navistar with a principal amount of $25,504,000 and a purchase price adjustment of $2,710,000 based on the estimated difference between the Net Tangible Assets (as defined in the Asset Purchase Agreement) as of the Closing Date and the Net Tangible Assets as of January 31, 1996, Nomura noted that the aggregate consideration payable to Navistar pursuant to the Acquisition represented 11.60x estimated 1996 net income of Columbus Plastics, 1.30x estimated tangible book equity of Columbus Plastics, 0.68x estimated 1996 revenues of Columbus Plastics, 7.19x estimated 1996 operating income ("EBIT") and 5.32x estimated 1996 operating income plus depreciation and amortization ("EBITDA") of Columbus Plastics.

Comparable Transactions Analysis. Nomura compared the consideration payable to Navistar pursuant to the Acquisition to the consideration paid in certain merger and acquisition transactions in the automotive/ truck and plastic parts industry since 1990. There have been a very limited number of publicly disclosed transactions that have occurred over the last few years in the automotive/truck and plastic parts industry and therefore a very wide range of multiples were obtained from this analysis. The transactions reviewed were: Vemco Acquisition Corp.'s acquisition of Bailey Corp.; Lear Corp.'s acquisition of Automotive Industries Holdings; Collins & Aikman Corp.'s acquisition of Larizza Industries, Inc. and Automotive Industries Holdings' acquisition of the Gulfstream division of O'Sullivan Corp. The analysis showed a range of total consideration to latest twelve months ("LTM") revenues multiples of 0.40x to 1.37x with a mean of 0.83x, a range of total consideration to LTM EBITDA multiples of 6.00x to 11.00x with a mean of 8.00x, a range of total equity value to tangible book value of 0.90x to 7.10x with a mean of 3.57x, and a range of total equity value to LTM net income of 10.00x to 16.40x with a mean of 13.20x.

Comparable Public Companies Analysis. Nomura performed an analysis of the equity value to LTM and current fiscal year ended multiples for six automotive/truck and plastic parts supplier companies, consisting of Bailey Corp., Mascotech, Inc., Arvin Industries, Inc., Collins & Aikman Corp., GenCorp., Inc. and Lear Corp, (the "Comparable Companies"). This analysis indicated that (i) the total capitalization ratio of the Comparable Companies as a multiple of LTM revenues ranged from 0.43x to 0.92x with a mean of 0.64x, as a multiple of LTM EBITDA ranged from 4.67x to 9.63x with a mean of 6.50x, and as a multiple of LTM EBIT ranged from 6.65x to 13.65x with a mean of 9.70x; (ii) the market capitalization ratio of the Comparable

33

Companies as a multiple of LTM net income ranged from 17.15x to 28.48x with a mean of 22.29x and as a multiple of book equity ranged from 1.21x to 20.04x with a mean of 6.09x; and (iii) the public trading market price per share as a multiple of current fiscal year earnings per share and next fiscal year earnings per share ranged from 6.82x to 14.77x with a mean of 11.46x and 6.00x to 11.61x with a mean of 9.61x, respectively.

Discounted Cash Flow Analysis. Nomura calculated and analyzed the present value of the future stream of operating cash flows that Core Materials would produce over the next five fiscal years through 2001 under three sets of projected financials consisting of a base scenario, which was provided to Nomura by the Company, a pessimistic scenario and an optimistic scenario. Under the pessimistic scenario, Nomura assumed a decline of 10% in revenue for fiscal year 1997 and held that revenue figure constant for the next four fiscal years through 2001, and a decline in gross margin. Under the optimistic scenario, Nomura assumed an increase of 10% in revenues for fiscal year 1997 and held that revenue figure constant for the next four fiscal years through 2001, and an increase in gross margin. Nomura then capitalized the post-2001 operating cash flows by calculating a terminal value based on a 5.50x to 6.50x range of multiples of EBITDA projected for Core Materials under all three scenarios for the year 2001. The cash flow streams and terminal values were then discounted to present values using a 10% to 15% range of discount rates for all three scenarios.

Nomura performed the discounted cash flow analysis assuming that the Closing would occur on December 31, 1996. Nomura noted that (i) under the base scenario projections given by the management of the Company, the holders of Company Common Stock would have an imputed midrange per share valuation of $2.67, (ii) under the pessimistic scenario, the holders of Company Common Stock would have an imputed midrange per share valuation of $1.73, and (iii) under the optimistic scenario, the holders of Company Common Stock would have an imputed midrange per share valuation of $3.62.

Expected Stockholder's Return Analysis. Nomura analyzed and considered the expected return on the Company Common Stock both with and without giving effect to the Acquisition for an investment period of five years beginning in fiscal year 1997. During this period, Nomura assumed that without the Acquisition and without a change in the Company's operating assets which mostly consist of cash and cash equivalents, the Company Common Stock price would increase at a rate of 5% per annum. This analysis, based on an aggregate price per share of $1.31 (the May 6, 1996 closing price of Company Common Stock, approximately one week prior to the public announcement of the potential Acquisition) yielded an imputed price per share of $1.76 by the year 2001. Nomura then calculated the imputed price per share in the year 2001 under all three scenarios for Core Materials as described above, based on a valuation of 6.00x projected 2001 EBITDA. This analysis yielded an imputed price per share of $3.95 under the base scenario (representing an internal rate of return of 20.1%), $2.77 under the pessimistic scenario (representing an internal rate of return of 13.3%), and $4.69 under the optimistic scenario (representing an internal rate of return of 23.6%).

Qualitative Factors. Nomura considered certain qualitative factors in evaluating the relative imputed per share values of Core Materials Common Stock, including the cyclicality of the sheet molding plastics business, the existence of unionized labor in the business, the ability of Core Materials to find future funding for working capital and other such factors that may potentially impact the future returns generated by Core Materials.

The foregoing is a summary of the financial analyses used by Nomura in connection with rendering its opinion. The preparation of a fairness opinion is a complex process and is not necessarily susceptible to partial analysis or summary description. Selecting portions of the analyses or of the summary set forth above, without considering the analyses as a whole would create an incomplete view of the processes underlying Nomura's opinion. In arriving at its opinion, Nomura considered the results of all such analyses. The analyses were prepared solely for the purposes of Nomura providing its opinion as to the fairness of the Acquisition, from a financial point of view, to the stockholders of the Company and do not purport to be appraisals or necessarily reflect the prices at which businesses or securities actually may be sold. No company used in the comparable company analyses summarized above is identical to Columbus Plastics or the Company and no transaction used in the comparable transaction analyses summarized above is identical to the Acquisition. Any analysis of the fairness of the Acquisition, from a financial point of view, to the stockholders of the Company involves complex considerations and judgments concerning differences in the potential financial and operating characteristics of the Comparable Companies and transactions and other factors in relation to the trading and

34

acquisition values of the Comparable Companies. Analyses based upon forecasts of future results are not necessarily indicative of actual future results, which may be significantly more or less favorable than those suggested by such analyses. As described above, Nomura's opinion and the related presentations to the Company's Board of Directors on September 6 and 12, 1996 was one of many factors taken into consideration by the Company's Board of Directors in making its determinations to approve the Asset Purchase Agreement. The foregoing summary does not purport to be a complete description of the analyses performed by Nomura.

Nomura's opinion addresses only the fairness of the Acquisition from a financial point of view to the stockholders of the Company and does not constitute a recommendation to any stockholder of the Company as to how such stockholder should vote with respect to the approval of the proposed transactions. Although Nomura evaluated the financial terms of the Acquisition, Nomura did not recommend the specific consideration to be paid in the Acquisition. The consideration to be received by Navistar as a result of the Acquisition was determined by negotiation between Navistar and the Company. In addition, Nomura was not requested to opine as to, and its opinion does not address, the underlying business decision of the Company's Board of Directors to proceed with or effect the Acquisition.

The Company will pay Nomura a fee of $325,000 for its services in evaluating the Acquisition and in rendering the opinion. The Company has also agreed to reimburse Nomura for certain expenses reasonably incurred by Nomura and to indemnify and hold Nomura harmless against certain expenses and liabilities arising in connection with its engagement.

Nomura is an internationally recognized investment banking firm and is regularly engaged in the valuation of businesses and their securities in connection with mergers and acquisitions, underwritings, secondary distribution of listed and unlisted securities, private placements and valuations for corporate, estate and other purposes. Nomura had no prior business relationships with the Company. From time to time, in the ordinary course of business, Nomura may trade equity securities of the Company and Navistar for its own account or for the accounts of customers and accordingly may at any time hold a long or short position in such securities.

INTERESTS OF CERTAIN PERSONS IN THE TRANSACTIONS

In considering the recommendation of the Company's Board of Directors with respect to the Asset Purchase Agreement and the transactions contemplated thereby, including the Stock Issuance and the Merger, stockholders should be aware that certain members of the Company's management and Board of Directors and Hellmold have certain interests in the transactions that are in addition to and potentially in conflict with the interests of the Company and the Company's stockholders generally. The Board of Directors of the Company was aware of these interests and considered them, among other matters, in approving the Asset Purchase Agreement and the transactions contemplated thereby.

Payment of Compensation to Mr. Prine. In recognition of Mr. Prine's services in connection with negotiating the Acquisition, the Board of Directors of the Company has authorized the payment of $125,000 to Mr. Prine contingent upon the consummation of the Acquisition.

Hellmold's Dual Representation. Hellmold was engaged by the Company to assist it in identifying and contacting potential acquisition candidates and assisting the Company in structuring and negotiating a strategic acquisition. In addition, Hellmold was engaged by Navistar to assist it in selling its Columbus Plastics Operations.

Pursuant to a letter agreement dated as of November 1, 1995, as amended on April 10, 1996 and July 18, 1996, the Company has paid Hellmold a retainer of $75,000 and has agreed to pay to Hellmold a transaction fee upon consummation of the Acquisition equal to the sum of (1) 3.33% of the first $15 million of the consideration paid in the Acquisition and (2) 0.75% of the value of the consideration paid in the Acquisition in excess of $15 million. For purposes of the letter agreement, "consideration" means the total value of all cash, securities, other property and any other consideration, including, without limitation, any contingent, earned or other consideration, paid or payable, directly or indirectly to Navistar in connection with the Acquisition and includes any indebtedness, including, without limitation, unfunded pension liabilities, retiree medical benefits liabilities, guarantees and other obligations, assumed in connection with the Acquisition. The $75,000

35

previously paid to Hellmold will be credited against the transaction fee payable to Hellmold. The Company also agreed to reimburse Hellmold for its out-of-pocket expenses and to indemnify Hellmold against certain liabilities, arising out of or in connection with the services rendered by Hellmold under its engagement.

Pursuant to a letter agreement dated as of May 31, 1995, Navistar International Corporation has paid Hellmold a retainer of $75,000 and has agreed to pay to Hellmold a transaction fee upon consummation of the sale of Columbus Plastics, equal to the sum of (1) 2.0% of the first $15 million of the consideration paid for Columbus Plastics, (2) 2.3% of the next $5 million of the value of the consideration paid for Columbus Plastics, (3) 2.6% of the next $5 million of the value of the consideration paid for Columbus Plastics and (4) 2.9% of the value of the consideration paid in excess of $25 million. Consideration for purposes of the Navistar letter agreement is substantially equivalent to that provided for in the Company letter agreement. The $75,000 previously paid to Hellmold by Navistar will be credited against the transaction fee payable by Navistar to Hellmold. Navistar also agreed to reimburse Hellmold for its out-of-pocket expenses and to indemnify Hellmold against certain liabilities arising out of or in connection with the services rendered by Hellmold under its engagement.

Stock Option. At the time of the consummation of the Merger, each outstanding option to purchase shares of Company Common Stock (each, a "Company Option") granted under any stock option plan of the Company will be deemed amended to constitute an option to acquire, at the same price per share, the same number of Core Materials Common Stock as the holder of the Company Option would have been entitled to receive pursuant to the Merger had such holder exercised such Company Option in full immediately prior to the consummation of the Merger (not taking into account whether such Company Option was in fact exercisable at such time).

As of the Record Date, the following executive officers and directors of the Company held outstanding Company Options:

                                                                   NUMBER OF SHARES OF COMPANY COMMON STOCK

(1) These options will vest at the earlier of (i) the consummation of the Acquisition and (ii) July 1, 1997.

Indemnification. Pursuant to the Asset Purchase Agreement, Navistar has agreed that for the period from the Closing Date through the sixth anniversary thereof, it shall not vote in favor of or otherwise directly or indirectly support any amendment of the provisions of Core Materials' By-laws relating to the indemnification of officers and directors which would have an adverse effect on the Company's present or former officers or directors of the Company (except to the extent that withholding any such vote would be in contravention of any applicable law).

Possible Employment of Mr. Conte. Mr. Conte and Navistar have had discussions concerning Mr. Conte's possible employment with Core Materials as its chief financial officer. No decision has been made as to whether Mr. Conte will be retained as Core Materials' chief financial officer. The respective obligations of the Company and Navistar to consummate the transactions contemplated by the Asset Purchase Agreement are not conditioned upon Mr. Conte's employment with Core Materials.

BUSINESS OF THE COMPANY

The Company was incorporated in the State of Maryland on July 1, 1988. Prior to 1994, the Company was primarily engaged in making investments in mortgage derivative securities and, to a lesser extent, mortgage related investments, all of which are secured by single-family residential mortgage loans. The Company also generates revenues from other sources, such as interest earnings on certain investments of the Company and sales of certain investments of the Company.

The Company has elected to be taxed as a REIT under the Code. As long as the Company qualifies as a REIT, dividends paid to stockholders will be allowed as a deduction for purposes of determining income subject to federal corporate income tax. As a result, as long as the Company qualifies as a REIT, the Company will not be subject to such tax on that portion of its net income that is distributed to stockholders. If the Acquisition is consummated, Core Materials will no longer qualify as a REIT and will be subject to income and franchise taxes on its income to the extent that it cannot offset such income with net operating losses or capital loss carryforwards.

Since May 1992, the Company has not purchased any new mortgage derivative or mortgage related investments. During 1995, the Company purchased one 7% FNMA guaranteed pass-through certificate backed by 30 year single-family mortgage loans of which the Company maintains 100% ownership. The current principal balance is approximately $3.4 million. During the period from the Company's inception in 1988 through early 1992, mortgage interest rate levels and prepayment speeds remained within ranges existent from 1970 to early 1992.

From early 1992 to early 1994, mortgage rates declined to levels lower than those existent for the prior twenty year period and, in fact, in the fall of 1993, declined to the lowest level in twenty-five years. The decline in mortgage rates and the availability of mortgage monies from a wide variety of lenders produced an unprecedented level and sustained duration of mortgage refinancings which directly resulted in unparalleled rapid mortgage prepayments.

Initially, the result of such prepayment levels sharply reduced interest and dividend earnings on the Company's assets. As the duration of these rapid prepayments extended, the Company's cash flows from interest and dividends and returns on invested principal were severely impaired, eventually being reduced to levels sufficient only to repay the Company's borrowings, pay operating expenses and fund minimal dividend distributions. This deterioration of asset performance began in the second quarter of 1992 and continued throughout 1993 and 1994, causing permanent impairment to a number of the Company's assets. For a substantial portion of the Company's assets, especially those with substantial cost basis premiums, the rapid prepayment scenario produced cash flows that did not recover the Company's investment basis.

Simultaneously, generally accepted accounting principles required quarterly asset valuations that produced write-downs in the value of a majority of Company assets. Such write-downs were reflected as reductions to the interest revenues on the Company's Statement of Revenues and Expenses.

The result of these earnings difficulties and the altered mortgage securities market that emerged after the prepayment cycle of 1992-1994 caused the Company's Board of Directors in mid-1994 to determine that the Company would not pursue its historical line of business and would investigate alternative opportunities to maximize stockholder value. The Company has maintained a portfolio of assets from its historical business, selectively selling assets to generate liquidity as market conditions were appropriate. See "--Reasons for and Background of the Acquisition".

A complete description of the Company's business, properties and legal proceedings, as well as audited historical financial statements of the Company and its subsidiaries, and management's discussion and analysis of the Company's financial condition and results of operations, is incorporated by reference to the Company's Annual Report in Form 10-K for the year ended December 31, 1995 and Quarterly Report on Form 10-Q for the quarter ended June 30, 1996, copies of which are contained within this Proxy Statement/Prospectus as Annexes VII and VIII, respectively.

BUSINESS OF COLUMBUS PLASTICS

In addition to the historical information contained herein, certain statements under this caption constitute "forward-looking statements" under the Reform Act which involve risks and uncertainties. Columbus Plastics' actual results may differ significantly from those discussed herein. Factors that might cause such a difference include, but are not limited to, those discussed under the captions "Risk Factors" and "Management's Discussion and Analysis of Results of Operations and Financial Condition of Columbus Plastics" as well as those discussed elsewhere in this Proxy Statement/Prospectus.

General

Columbus Plastics operates principally in one business segment, the production of high quality compression Sheet Molding Composite ("SMC") fiberglass reinforced parts. Columbus Plastics has been a wholly-owned operating unit of Navistar's truck manufacturing operations since Columbus Plastics' formation in late 1980.

Industry

SMC plastics are part of a larger family of materials collectively known as "reinforced plastics." Reinforced plastics are combinations of resins and reinforcing fibers formed through high or low pressure fabrication techniques.

Reinforced plastics compete largely against metals and have the strength to function well during prolonged use. Management believes that reinforced plastic components offer many advantages over metals, including:

- heat resistance

- corrosion resistance

- lighter weight

- lower cost

- greater flexibility in product design

- part consolidation for multiple piece assemblies

- lower initial tooling costs for lower volume applications

- high strength-to-weight ratio

- dent-resistance in comparison to steel or aluminum.

The largest markets for reinforced plastics, by volume of production, are automotive and land transportation, construction, corrosion-resistant products, marine, and electrical and electronic applications.

Competition for OEM business usually involves a competitive selection process in which the OEM solicits bids for the production of a component. After assessing a supplier's ability to manufacture the component, the OEM selects a supplier to work with the OEM's design team. The plastic supplier is generally selected to supply a component a year or two in advance of production. Once selected, the plastic supplier generally supplies the component for the life of the product model. Columbus Plastics products have model lives that range from approximately two to eight years.

Columbus Plastics' major competitors include Budd Plastics, Cambridge Industries, Eagle-Picher, Goodyear Plastics and Molded Fiberglass Corporation. Columbus Plastics believes that it is one of the largest producers of SMC in the United States and Canada. Columbus Plastics competes primarily on material design and manufacturing capability, product quality, cost, delivery and customer service.

Major Customers

Columbus Plastics currently has two major customers, Navistar and Yamaha. The loss of a significant portion of sales to Navistar or Yamaha would have a material adverse effect on Columbus Plastics' business.

38

See "Risk Factors--Control by Navistar; Anti-Takeover Effects," "--Relationships and Reliance on Navistar" and "--Dependence on Major Customers."

RELATIONSHIP WITH NAVISTAR

Columbus Plastics enjoys a long-standing relationship with Navistar's truck manufacturing division and is currently the sole supplier to Navistar's truck manufacturing division for all of its demand of SMC products. Navistar manufactures and markets medium- and heavy-duty trucks, including school bus chassis, mid-range diesel engines and service parts in North America and in selected export markets. Columbus Plastics makes products for Navistar's Chatham (Canada) assembly plant and Springfield, Ohio, assembly and body plants. Columbus Plastics currently works closely on new product development with Navistar's engineering and research personnel at Navistar's Fort Wayne, Indiana, Technical Center. Columbus Plastics also currently receives support from Navistar in the form of staff management, materials purchasing, and working capital management.

The Columbus Plastics' facility was opened in 1980 to fulfill Navistar's need for higher quality fiberglass hoods. Until the addition of Yamaha personal watercraft products in 1990, production sales growth at Columbus Plastics was largely driven by Navistar's increased use of SMC material in its trucks. The facility began production in late 1980, producing hoods for Navistar medium-duty trucks. Since 1986, air deflectors, air farings, fenders, splash panels, engine covers and other components for Navistar trucks were added to the Columbus Plastics product line.

The North American truck market in which Navistar competes is highly competitive and the demand for trucks is subject to considerable volatility as it moves in response to cycles in the overall business environment and is particularly sensitive to the industrial sector, which generates a significant portion of the freight tonnage hauled. Truck demand also depends on general economic conditions, among other factors. Sales to Navistar amounted to approximately 63%, 74% and 73% of total revenues in 1995, 1994 and 1993, respectively.

RELATIONSHIP WITH YAMAHA

Columbus Plastics enjoys a long-standing relationship with Yamaha and currently supplies a significant amount of the SMC products for Yamaha's personal watercraft. The addition of Yamaha's personal watercraft component business in 1990 represented Columbus Plastics' first major outside business undertaking. Products produced for Yamaha include decks, hulls, engine hatches, bulk heads, and reinforcements.

Columbus Plastics has worked closely with Yamaha over the last five years to improve collectively the surface quality of Yamaha products and has identified new process control techniques and improved materials.

The diversification into a new market area uncorrelated to truck demand has allowed Columbus Plastics to fill in production gaps that would have occurred during periods of lower demand for medium- and heavy-duty trucks. Demand for products from Yamaha is related to the level of general economic activity and specifically to the cyclical nature of the personal watercraft industry among other factors.

Sales to Yamaha amounted to approximately 34%, 23% and 23% of total revenues in 1995, 1994 and 1993, respectively.

OTHER CUSTOMERS

Columbus Plastics performs secondary operations such as assembly of components and prime painting for its customers. The Columbus Plastics facility is designed for continuous flow manufacturing. In addition, Columbus Plastics sells SMC material directly to third parties.

Products

SMC SHEET MATERIAL PRODUCTION

Columbus Plastics incorporates a sophisticated computer program that assists in the compounding of various complex SMC formulations tailored to customer needs. The system provides for the following:

39

- Control information during various production processes; and

- Data for statistical batch controls.

Columbus Plastics will have the capacity to manufacture approximately 45 million pounds of SMC sheet material annually, once the planned installation of an additional SMC compounding machine is completed, which is expected to occur in January 1997. Production of SMC by Columbus Plastics for the years ended October 31, 1995, 1994 and 1993 was as follows:

                                                        SMC POUNDS

BACKLOG

Columbus Plastics relies on production schedules provided by Navistar and Yamaha to plan and implement production. These schedules are provided to Columbus Plastics on a monthly basis and are considered firm for the current period. Navistar and Yamaha can update these schedules daily for changes in demand that allows them to run their inventories on a "just-in-time" basis. Accordingly, the ordered backlog at Columbus Plastics was de minimis as of October 31, 1995, 1994 and 1993.

RAW MATERIALS AND SUPPLIERS

The principal raw materials used in the SMC compounding include: polyester resin, fiberglass rovings and adhesives. Currently, there are at least two suppliers for each of the raw materials Columbus Plastics uses and Columbus Plastics believes it currently has access to an ample supply of these raw materials.

CAPACITY CONSTRAINTS

Columbus Plastics believes improvements in uptime performance offer the best, and usually the most cost effective means of increasing existing capacities and providing opportunities to pursue new business growth. Columbus Plastics has on occasion in the past been required to work a seven day/three shift schedule to meet Navistar and Yamaha production requirements.

MOLDING

Columbus Plastics currently owns or leases 17 presses, ranging in size from 500 to 4500 tons. Large presses provide Columbus Plastics with the ability to manufacture very large molded plastic parts. Columbus Plastics believes that no other molder has this number of large capacity presses.

Columbus Plastics has both vacuum molding and in-mold coating capabilities and currently operates eleven robots and two automatic guided vehicles that assist in material handling, machining, and adhesive application.

ASSEMBLY AND PAINT

Columbus Plastics has the ability to assemble and/or prime paint a wide variety and volume of products. To enhance the surface quality and paint finish, Columbus Plastics developed a significant in-mold coating capability. In-mold coating is a manufacturing process performed by injecting a liquid over the molded part surface and then applying pressure at elevated temperatures during an extended molding cycle. The liquid coating serves to fill and/or bridge surface porosity as well as provide a barrier against solvent penetration during subsequent top-coating operations. Columbus Plastics believes that it is among the industry leaders in in-mold coating applications, based on the size and complexity of parts coated and the number of presses, 13 of 17, that are in-mold coating capable.

40

Capital Expenditures and Research and Development

Capital expenditures totaled approximately $7.3 million, $2.0 million and $1.4 million for the years ended October 31, 1995, 1994 and 1993, respectively. The increase in 1995 primarily relates to three large presses which were brought on line in 1996. Capital expenditures consist of presses and other equipment to manufacture Navistar truck components and Yamaha personal watercraft parts as well as laboratory equipment, storage equipment, computers and office furniture and fixtures.

Product development is a continuous process at Columbus Plastics. Research and development activities focus on developing new SMC formulations and improving existing products and manufacturing processes.

Columbus Plastics does not have a separate research and development facility but uses its production equipment (compounding machines, molding presses, and primer system), as necessary, to support these efforts and cooperates with Navistar and its resin supplier in its research and development efforts. Likewise, manpower to direct and advance research and development is integrated with the existing manufacturing, engineering, production, and quality organizations. Management of Columbus Plastics has estimated that internal costs related to research and development activities approximate $200,000 per year.

Major research and development projects of current focus at Columbus Plastics include the following:

- Develop low pressure SMC applications to achieve lower initial tooling costs and shorter lead times;

- Reduce the densities of SMC formulations to mold lighter components without sacrificing physical or cosmetic properties;

- Use recycled SMC parts as filler to be environmentally proactive and reduce waste cost;

- Complement current liquid in-mold-coating applications with powder in-mold-coating development to expand the number of sealed substrate surfaces on large-sized components; and

- Develop alternate primers for environmental, quality and cost advantages.

Environmental Compliance

Columbus Plastics manufacturing operations are subject to federal, state and local environmental laws and regulations which impose limitations on the discharge of pollutants into the air and water and establish standards for the treatment, storage and disposal of hazardous waste. Columbus Plastics' policy is to conduct its business with due regard for the preservation and protection of the environment. Columbus Plastics environmental waste management involves the daily auditing of all satellite hazardous waste accumulation points, weekly audits of all hazardous waste activities and biennial audits of every authorized treatment, storage and disposal facility. Columbus Plastics' environmental staff also trains each new employee on waste management and other environmental issues as part of an initial orientation process, and annually thereafter.

Columbus Plastics has submitted the information necessary for the granting of a Title V permit, as required under the Clean Air Act. In 1989, Columbus Plastics installed a Regenerative Thermal Oxidizer ("REECO"). The purpose of the REECO system is to destroy volatile organic compounds from the coating operation. Columbus Plastics' current emission permits allow for 15 lbs./day of volatile organic compound emission. The REECO system allows Columbus Plastics to meet these limitations by consistently achieving about 95% destruction efficiency. Columbus Plastics has spent over $100,000 in the past year to maintain the system, thus extending the reliability of the system another 5 to 7 years. Columbus Plastics believes that it is in compliance with all RCRA and CERCLA laws. Compliance with these environmental laws and regulations has not had, nor is it currently expected to have, a material effect on Columbus Plastics' operations, competitive position or capital expenditures through fiscal year 1997. The amount of capital expenditures currently expected to be spent on environmental compliance over the next two years is not significant.

Employees

As of October 31, 1995, Columbus Plastics employed a total of 423 employees, 343 of whom are covered by a collective bargaining agreement. After a 15 day strike in August 1995, Columbus Plastics concluded a collective bargaining agreement with the IAM covering the hourly employees. The contract expires in

41

August of 1998 and provides for 3% annual wage increases in August 1995, 1996 and 1997 with a reduction in benefit costs. This net increase was offset in part by a new two-tier wage system for new hires.

Patents, Trade Names and Trademarks

Navistar applies for and maintains patents, trade names and trademarks where Navistar believes that such patents, trade names and trademarks are reasonably required to protect Columbus Plastics' rights in its products. Navistar and Columbus Plastics do not believe that any single patent, trade name or trademark or related group of such rights are materially important to Columbus Plastics' business or its ability to compete.

Properties

Columbus Plastics consists of a single plant that is situated approximately nine miles west of the center of Columbus, Ohio, at 800 Manor Park Drive. The 306,656 square-foot facility currently consists of manufacturing, office and warehouse buildings on 28.2 acres of land.

The 306,656 square feet of available floor space at Columbus Plastics comprises the following:

                                                                   APPROXIMATE

Columbus Plastics produces SMC sheet material and molds fiberglass, reinforced parts. Currently, Columbus Plastics has SMC sheet production capacity adequate for its production volume and there exists third parties from whom Columbus Plastics could purchase SMC sheet material. The approximate capacity utilization for the molding of production products was 122% in 1995, 102% in 1994 and 99% in 1993. During 1996, the three new presses put into operation at Columbus Plastics have increased the available capacity for the molding of production products.

Legal Proceedings

Columbus Plastics is not currently a party to any material pending legal proceedings, other than ordinary, routine litigation incidental to the business, nor are any such proceedings known by management to be contemplated by government authorities.

(1) Columbus Plastics provides Navistar's truck assembly operations with all of its sheet molding composite plastic component requirements, which represents greater than 60% of its output in all periods presented, at standard cost, with the remainder sold to unrelated third party customers at negotiated prices.

(2) Interest, income taxes and earnings per share have been omitted because Columbus Plastics was not a separate stand alone division or subsidiary of Navistar and was generally not accounted for separately. In addition, Navistar's systems and procedures do not provide sufficient information to develop a reasonable cost allocation of income taxes, corporate debt and interest expense.

MANAGEMENT'S DISCUSSION AND ANALYSIS
OF RESULTS OF OPERATIONS AND
FINANCIAL CONDITION OF
COLUMBUS PLASTICS

Certain statements under this caption constitute "forward-looking statements" under the Reform Act which involve risks and uncertainties. Columbus Plastics' actual results may differ significantly from the results discussed in such forward-looking statements. Factors that might cause such a difference include, but are not limited to, those discussed under the caption "Risk Factors."

OVERVIEW

Columbus Plastics manufactures high quality compression SMC fiberglass reinforced parts. Columbus Plastics has been a wholly-owned operating unit of Navistar's truck manufacturing division since Columbus Plastics formation in late 1980. Columbus Plastics has two major customers, Navistar and Yamaha. The demand for Columbus Plastics products is affected by the volume of purchases from these two customers, whose orders are primarily affected by economic conditions in the United States. Columbus Plastics' manufacturing operations have a significant fixed cost component. Accordingly, during periods of changing demands the profitability of Columbus Plastics' operations will change proportionately more than revenues from operations.

Columbus Plastics is not a stand alone division or subsidiary of Navistar. Navistar provides Columbus Plastics with certain management support and corporate treasury, legal, tax, computer, purchasing and other similar corporate support functions. Corporate general and administrative expenses have not been previously allocated to Columbus Plastics. For purposes of preparing the financial statements of Columbus Plastics certain of these corporate costs along with other Navistar Truck Group expenses were allocated using an allocation method that management believes is reasonable and reflective of those costs that would have been incurred on a stand alone basis. However, Navistar's systems and procedures do not provide sufficient information to develop reasonable cost allocations for income taxes, corporate debt and interest expense. In addition, Columbus Plastics records sales to Navistar at its standard cost. Accordingly, the results of operations as recorded in the financial statements and discussed below may not be indicative of the results of operations of Columbus Plastics had it been a stand alone company during the periods presented.

Pursuant to the Asset Purchase Agreement, Navistar and Core Materials will enter into a Comprehensive Supply Agreement (the "Supply Agreement") with an initial term of five years. Under the terms of the Supply Agreement, Navistar will agree to purchase from Core Materials, and Core Materials will agree to sell to Navistar at negotiated prices, which will approximate fair value, all of Navistar's original equipment and service requirements for fiberglass reinforced parts using the SMC process for components currently being manufactured by Columbus Plastics and detailed in the Supply Agreement. The pro forma sales and gross margin amounts have been adjusted to reflect the Supply Agreement. The pro forma amounts are shown in parenthesis next to the historical amounts.

Results of Operations

FISCAL YEAR 1995 COMPARED WITH FISCAL YEAR 1994

Net Sales for 1995 totaled $59.5 million ($65.6 million) up 35% (33%) over the $44.2 million ($49.2 million) in 1994. Shipments to Navistar increased 16% (16%) to $37.8 million ($43.6 million) from the $32.5 million ($37.6 million) in 1994. The increase in shipments to Navistar was the result of an increase in sales of Navistar trucks due to an increase in truck industry demand in the United States and Canada. Sales to Yamaha in 1995 increased by 95% to $20.2 million compared with the $10.4 million in 1994. This increase resulted from an increase in demand for Yamaha's watercraft products and improved pricing.

Gross margin was 10% (19%) of sales in 1995 compared with 8% (18%) in 1994. The increase in gross margin was primarily the result of the increase in sales volumes, improved pricing, capacity utilization and operating efficiency. These improvements were partially offset by higher labor and overtime costs to meet the demand for both Navistar and Yamaha products. Gross margin in 1995 was also adversely impacted by a 15 day strike by Columbus Plastics' hourly workers during the fourth quarter.

44

Marketing and administrative expenses were $484,000 in 1995 compared with $390,000 in 1994. The increase was primarily the result of the hiring of new employees and increased support costs to meet the increased production demand in 1995.

FISCAL YEAR 1994 COMPARED WITH FISCAL YEAR 1993

Net Sales for 1994 totaled $44.2 million ($49.2 million) up 11% (11%) over the $39.8 million ($44.3 million) in 1993. Shipments to Navistar increased 12% (12%) to $32.5 million ($37.6 million) from the $28.9 million ($33.4 million) in 1993. The increase in shipments to Navistar was the result of an increase in sales of Navistar trucks due to an increase in truck industry demand in the United States and Canada. Sales to Yamaha in 1994 increased by 14% to $10.4 million compared with the $9.1 million in 1993. This increase resulted from an increase in demand for Yamaha's watercraft products and improved product mix.

Gross margin was 8% (18%) of sales in 1994 compared with 3% (13%) in 1993. The increase in gross margin was primarily the result of the increase in sales volumes, capacity utilization, and improved product mix. These improvements were partially offset by higher labor and overtime costs to meet the demand for both Navistar and Yamaha products.

Marketing and administrative expenses were $390,000 in 1994 compared with $369,000 in 1993. The increase was primarily the result of the hiring of new employees and increased support costs to meet the increased production demand in 1994.

NINE MONTHS ENDED JULY 31, 1996 COMPARED WITH THE NINE MONTHS ENDED JULY 31,
1995

Net Sales during the 1996 period totaled $39.2 million ($43.3 million) down 11% (10%) from the $43.9 million ($48.2 million) in 1995. Shipments to Navistar decreased 16% (15%) to $23.2 million ($27.1 million) from the $27.5 million ($31.8 million) in 1995. The decrease in shipments to Navistar reflects lower volume of Navistar truck sales due to a decline in truck industry demand in the United States and Canada. Sales of $15.2 million to Yamaha in 1996 were unchanged from the level in 1995.

Gross margin was 2% (11%) in 1996 compared with 11% (19%) in 1995. The decrease in gross margin was primarily driven by the reduction in sales volumes which resulted in lower capacity utilization and overhead absorption. Fixed manufacturing costs in 1996 were higher than 1995 due to increased depreciation expense resulting from the installation of three new SMC presses that became operational in 1996. In addition, the 1996 gross margin was adversely impacted by start up costs related to the tooling for a new product, increased labor costs resulting from the new three year labor agreement with hourly employees and increased repair and maintenance costs relating to projects that had been deferred in 1995 due to production volumes.

Marketing and administrative expenses were $337,000 in 1996 compared with $363,000 in 1995. The decrease was primarily the result of the decreased production demand in 1996.

Liquidity and Capital Resources

Historically, Columbus Plastics' working capital and investment needs have been financed by Navistar through the intercompany equity investment account and through the sale of products to Yamaha. Subsequent to the transaction with the Company, Columbus Plastics will need to independently fund all of its working capital requirements. Funds necessary to meet its working capital and investment needs will be financed through the following sources: 1) the Supply Agreement between Navistar and Core Materials, while in effect, will require that Navistar obtain all of its SMC plastic requirements for components currently being manufactured by Columbus Plastics and detailed in the Supply Agreement from Columbus Plastics at negotiated prices which approximate fair value; 2) the Company has substantial NOLs that will be available to offset future income of Columbus Plastics subsequent to the acquisition. The utilization of these NOLs will substantially reduce any federal tax liability payments; and 3) Columbus Plastics' and the Company's management will engage in best efforts to obtain a working capital line of credit which will be available to fund the combined companies' working capital requirements. Management believes that internally generated funds

45

along with the other factors noted above will be sufficient to satisfy anticipated working capital needs and capital expenditures.

Business Outlook

Columbus Plastics is dependent on its two major customers, Navistar and Yamaha. During the first nine months of 1996, Navistar has experienced a significant decline in the rate of new truck orders and an increase in the cancellation rate of existing orders. Future demand for certain Columbus Plastics' products will be dependent on the rate at which new truck orders are received by Navistar. Columbus Plastics believes that production levels for Navistar for the remainder of the fiscal year will approximate the reduced levels experienced in the first nine months of 1996. Columbus Plastics also anticipates a decline in production of Yamaha products for the remainder of the fiscal year due to a reduction in the Yamaha order rate. Management will balance production with demand for the remainder of the fiscal year as appropriate to reduce the financial impact of lower sales volumes.

UNAUDITED PRO FORMA COMBINED FINANCIAL INFORMATION
OF CORE MATERIALS

The accompanying unaudited pro forma financial statements set forth the pro forma combined balance sheet of Core Materials at July 31, 1996 as if the Acquisition was effective on July 31, 1996; and the pro forma combined statements of income for the year ended October 31, 1995 and the nine months ended July 31, 1996 as if the Acquisition had occurred at the beginning of the periods presented. These pro forma financial statements are presented to illustrate the effect of certain adjustments to the historical financial statements that result from the proposed transactions between the Company and Navistar. Based upon the terms of the proposed acquisition, for financial reporting and accounting purposes the transaction will be accounted for as a reverse acquisition whereby Columbus Plastics will be deemed to have acquired Core Materials. However, Core Materials, subsequent to the merger, will be the continuing legal entity and registrant for both Securities and Exchange Commission filing purposes and income tax reporting purposes. Consistent with reverse acquisition accounting treatment Core Materials will carry forward the historical basis of the acquired assets and assumed liabilities of Columbus Plastics and will revalue the basis of its net assets to fair value. Should there be an additional contingent earn-out adjustment, it will be accounted for by increasing the amount of the Secured Note, and by reducing the amount of Core Materials' retained earnings.

The pro forma information is not necessarily indicative of the actual financial position of Core Materials at any date or the results which would have actually occurred had the transactions occurred on such dates or which may occur in the future. These statements should be read in conjunction with the historical financial statements and notes thereto included elsewhere herein or incorporated by reference herein.

YEAR ENDED OCTOBER 31, 1995 AND THE NINE MONTHS ENDED JULY 31, 1996

Unaudited Pro forma Combined Balance Sheet:

The Unaudited Pro forma Combined Balance Sheet as of July 31, 1996 reflects the adjustments necessary to record the proposed acquisition as though it occurred on July 31, 1996.

Based upon the terms of the proposed acquisition, the transaction for financial reporting and accounting purposes will be accounted for as a reverse acquisition whereby Columbus Plastics will be deemed to have acquired Core Materials. However, Core Materials, subsequent to the merger, will be the continuing legal entity and registrant for both Securities and Exchange Commission filing purposes and income tax reporting purposes. Consistent with reverse acquisition accounting treatment Core Materials will carry forward the historical basis of the acquired assets and assumed liabilities of Columbus Plastics and will revalue the basis of its net assets to fair value. For financial reporting purposes, consistent with reverse acquisition accounting treatment, the purchase price of Core Materials should be calculated as the fair value of the consideration paid or received whichever is more clearly evident. Because Core Materials' stock is thinly traded and supports a company with no current operations, the fair value of Core Materials' existing, outstanding common stock is not appropriate to determine the purchase price. The purchase price will be determined as the fair value of the consideration received (cash, investment, tax benefits and accrued liabilities) by Columbus Plastics. The purchase price, based upon reverse acquisition accounting, has been calculated at approximately $15 million and does not include any future contingent consideration payments. Transaction costs incurred in connection with the acquisition of a company without operating substance should be treated similar to that of an initial public offering as a reduction in paid-in capital. Since the recording of Navistar's transaction costs at Columbus Plastics would result in no net impact to Columbus Plastics' balance sheet, Navistar's transaction costs are excluded from the purchase price.

(a) Reverse acquisition accounting treatment requires that the retained earnings carried forward to Core Materials should consist of Columbus Plastics' equity investment account, less an amount equivalent to Navistar's share of Core Materials' common stock. This adjustment reclassifies Columbus Plastics' equity investment account into Common Stock and Retained Earnings by first allocating an amount equivalent to the par value of the shares issued to Navistar to Common Stock-par with the remainder being allocated to Retained Earnings. The historical retained earnings of the Company is reclassified to paid-in-capital.

(b) Represents the recording of the Secured Note payable to Navistar as consideration for the purchase by Core Materials of the assets and liabilities of Columbus Plastics. The offset of this pro forma entry is to retained earnings as reverse acquisition accounting treats the Secured Note as a deemed dividend to Navistar. The Secured Note recorded reflects the stated amount of the Secured Note ($25,504,000) plus an estimate of the post closing adjustment ($2,400,000) which will be calculated as the change in the equity investment account, as adjusted, between January 1, 1996 and the date of closing. The Asset Purchase Agreement provides for a contingent earn-out based upon future operations which will be paid to Navistar through an increase in the principal amount of the Secured Note and a reduction in Core Materials' retained earnings. As the contingent consideration is dependent upon future operating results which can not be determined at the time of the acquisition, no estimate of contingent earn-out has been included in the pro forma adjustments.

(c) Represents the projected pension benefit obligation in excess of the accumulated vested pension benefit obligation for the Columbus Plastics' salaried employees assumed by Core Materials after the consummation of the proposed acquisition.

(d) Represents the recognition of a deferred tax asset for the Company's net operating losses and capital loss carryforwards and the temporary difference between the book and tax basis of Core Materials' assets and liabilities (approximately $17,200,000). A deferred tax asset relating to the Company's loss carryforwards was not previously recognized due to the Company's status as a real estate investment trust. Due to

49

uncertainty in the ability of Core Materials to fully realize all of the loss carryforwards prior to their expiration, a valuation allowance of approximately $5,200,000 has been established against the deferred tax asset. Consistent with reverse acquisition accounting treatment, the establishment of the deferred tax asset has been offset against paid-in-capital since Columbus Plastics is the accounting acquiror.

(e) Represents the payment of transaction costs and certain severance and termination costs applicable to the Acquisition. See also Note (f).

(f) Represents certain severance and leasehold termination costs to close former Company facilities and terminate certain of the Company's employees. Amounts will be recognized at the date of the Acquisition as Columbus Plastics is the accounting acquiror.

(g) Represents the reduction in Columbus Plastics' accounts payable for the amount ($3,194,000) to be retained by Navistar.

CORE MATERIALS
NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS

YEAR ENDED OCTOBER 31, 1995 AND THE NINE MONTHS ENDED JULY 31, 1996

Unaudited Pro Forma Combined Statements of Income:

The Unaudited Pro Forma Combined Statements of Income for the twelve months ended October 31, 1995 and the nine months ended July 31, 1996 have been prepared assuming the proposed acquisition had occurred at the beginning of the periods presented and reflects the effects of certain adjustments to the historical financial statements that result from the proposed acquisition between Core Materials and Navistar. Columbus Plastics is not a stand alone division or subsidiary of Navistar and was generally not accounted for separately. Navistar's systems and procedures do not provide sufficient information to develop a reasonable cost allocation for income taxes and interest expense. Accordingly, historical net income per share amounts have not been included in the unaudited pro forma financial information for Columbus Plastics.

(a) The historical statements of income for the Company are included for the year ended December 31, 1995 and the seven months ended July 31, 1996, respectively, in the unaudited pro forma combined statements of income for the year ended October 31, 1995 and the nine months ended July 31, 1996, respectively. Consistent with reverse acquisition accounting treatment, historical statement of income information for the Company will not be included in the historical financial information of Core Materials after the consummation of the proposed acquisition. Accordingly, the Company's historical statements of income have been reversed from these unaudited pro forma financial statements as described in the adjustments noted below.

(b) Represents the additional revenues resulting from pricing sales by Core Materials to Navistar reflecting the prices specified in the Comprehensive Supply Agreement, rather than at Columbus Plastics historical standard cost.

(c) Represents the estimated interest expense on the Secured Note due Navistar at 8% per annum ($2,232,300 for the year ended October 31, 1995 and $1,674,200 for the nine months ended July 31, 1996); less the reversal of the Company's historical interest expense and the interest credit of $150,000 for the year ended October 31, 1995 and $280,000 for the nine months ended July 31, 1996, which represents the capitalization of interest on the secured note relating to property, plant and equipment under construction.

(d) Represents an estimate of the additional administrative expenses to be incurred by Core Materials as a result of Columbus Plastics' status as a stand alone, publicly owned company rather than an operating unit of a much larger corporation. Additional costs consist primarily of executive salary costs and legal and directors fees. Such costs are estimated at $864,000 for the year ended October 31, 1995 and $648,000 for the nine months ended July 31, 1996. The adjustment represents these amounts less the reversal of the Company's historical marketing and administrative expense, which includes approximately $2.4 million of transaction costs relating to the proposed merger and acquisition for the period ended July 31, 1996. The historical marketing and administrative expense of Columbus Plastics includes allocated corporate costs which are reflective of the costs that will be charged to Columbus Plastics pursuant to the Transitional Services Agreement between Core Materials and Navistar. Accordingly, no adjustments have been recorded to reflect the impact of the Transitional Services Agreement on the unaudited pro forma financial statements.

(e) Represents the estimated interest income to be earned on the mortgage backed security at the security's effective interest rate of 7% ($227,700 for the year ended October 31, 1995 and $170,700 for the nine months ended July 31, 1996); less the reversal of the Company's historical interest income.

(f) Represents the estimated income tax expense for Core Materials based upon a statutory Federal tax rate of 34% and an estimated Ohio state and local tax rate of 11%. The income tax expense recorded in the pro forma financial statements is not necessarily indicative of the cash payments for income taxes that Core Materials would be required to pay due to Core Materials' substantial NOLs and capital loss carryforwards. Core Materials expects to only be required to make minimal Federal income tax payments

as mandated, primarily, by the Alternative Minimum Tax regulations until such time that the loss carryforwards are fully utilized or expired.

(g) The weighted average shares outstanding used to calculate net income per share include the number of shares of Company common stock currently outstanding; the number of shares of Core Materials common stock to be issued to Navistar as consideration for the proposed acquisition; and the effect of the exercise of 260,000 dilutive Company common stock options, using the treasury stock method.

BUSINESS OF CORE MATERIALS AFTER
THE ACQUISITION

BUSINESS

In connection with the Acquisition, Core Materials will acquire substantially all of the assets and liabilities, including the property and business, of Columbus Plastics (other than certain excluded assets and liabilities). To the extent that any of the contracts to which Navistar or its affiliates are parties are included within the assets to be acquired by Core Materials and are not assignable or require the consent of third parties prior to assignment to Core Materials, upon request, prior to the Closing, Navistar will cooperate with the Company in any reasonable manner in connection with the Company's obtaining such consents; provided, however, that Navistar will not be obligated as part of its cooperation to expend money, commence litigation or offer or grant any accommodation to any third parties. If the Company and Navistar are unable to obtain a required consent and unable to obtain a separate agreement between Core Materials and the other party or parties, the Company shall have the right to require Navistar to use reasonable efforts to perform any such contract, to the extent it relates to Columbus Plastics, as agent for and for the account of Core Materials, and shall promptly remit any funds collected for the account of Core Materials, for a period of six months following the Closing Date; provided that Core Materials reimburse Navistar for any and all cash, expenses, losses and liabilities incurred in connection with taking such action. As discussed above under "--Business of the Company," since mid-1994, the Company has not pursued its historical business of engaging in investments in mortgage derivative securities and mortgage related investments; however, it has continued to maintain its historical business by holding such securities. After the Acquisition, Core Materials will continue to hold the Company's remaining investments in mortgage securities but the principal business of Core Materials will consist of operating the business and property of Columbus Plastics.

Core Materials' operational strategy will be to improve productivity, implement cost controls and expand Columbus Plastics' operations by expanding its customer base. After the Acquisition, the Company will close its current offices and the chief executive offices of Core Materials will be located at 800 Manor Park Drive, Columbus, Ohio.

RELATIONSHIP WITH NAVISTAR

After the Acquisition, Core Materials will continue to have a substantial relationship with Navistar. Two of Core Materials' five directors will be Navistar designees. Moreover, Navistar will receive 4,264,000 shares of Core Materials Common Stock in the Acquisition, which amount is subject to adjustment but shall not exceed 45% of the total number of shares of Core Materials Common Stock issued and outstanding on a fully diluted basis, thus giving Navistar the power to significantly influence the composition of Core Materials' Board of Directors and to approve actions requiring stockholder approval. See "RISK FACTORS--Control by Navistar; Anti-Takeover Effects."

Navistar will also be Core Materials' biggest customer. Columbus Plastics derived approximately 73%, 74%, 64% and 59% of its revenue from sales to Navistar (at Columbus Plastics' standard cost) in fiscal years 1993, 1994 and 1995 and the nine months ended July 31, 1996, respectively. On a pro forma basis, Core Materials would have derived approximately 67% and 63% of its revenue from sales to Navistar in fiscal year 1995 and the first nine months ended July 31, 1996, respectively, reflecting the Comprehensive Supply Agreement. The loss of a significant portion of sales to Navistar would have a material adverse effect on the business, financial condition and results of operations of Core Materials. While Core Materials will seek to diversify its customer base following the Acquisition, there can be no assurance that it will be successful in doing so.

Core Materials and Navistar will also have certain contractual arrangements following the Acquisition. See "RISK FACTORS--Relationships with and Reliance on Navistar" and "--Ancillary Agreements."

LIQUIDITY

In connection with the Acquisition, Core Materials will issue the Secured Note in the principal amount of $25,504,000. Among other things, the Secured Note will restrict the ability of Core Materials or any of its

55

subsidiaries to incur additional indebtedness, make investments, pay dividends or make other restricted payments on its capital stock, enter into any merger, consolidation or other extraordinary transaction or sell its assets. The Secured Note will call for periodic principal payments only if unrestricted cash of Core Materials exceeds $3 million. If no such excess exists, no principal payments (other than from certain proceeds of a Refinancing Loan described below) will be required until November 2006. See "--Ancillary Agreements-- The Secured Note."

Core Materials will seek to enter into a senior credit facility to provide working capital and for other purposes simultaneous with or shortly after the consummation of the Acquisition. There can be no assurance that Core Materials will be able to negotiate an acceptable senior credit facility.

Pursuant to the Secured Note, Core Materials will covenant to use reasonable commercial efforts to obtain a Refinancing Loan (as defined below) within six (6) months from the Closing Date in amounts and with terms reasonably satisfactory to Core Materials and Navistar (or its permitted successors, transferees and assigns). "Refinancing Loan" is defined by the Secured Note to mean any loan, extension of credit or other financial accommodation (other than a revolving line of credit for working capital purposes) made as of or after the Closing to Core Materials by a person other than the holder of the Secured Note; to refinance and pay indefeasibly in full or in part the outstanding principal amount the Secured Note, and which is secured by Core Materials' equipment or other assets securing the Secured Note, provided that (i) the proceeds of such loan are disbursed directly to the holder of the Secured Note pursuant to written authorization given by Core Materials to the person making the loan; and
(ii) to the extent such person intends to take a security interest in any of Core Materials' equipment or other assets, such person has entered into an intercreditor agreement with the holder of the Secured Note in form and substance acceptable to the holder of the Secured Note. In the event that Core Materials obtains any Refinancing Loan, it will be obligated pursuant to the terms of the Secured Note to pay, promptly upon obtaining such loan, principal on the Secured Note in an amount equal to the proceeds of such loan.

Core Materials expects that cash provided from operations, together with borrowings under its anticipated senior credit facility, will be sufficient to fund its interest requirements, capital expenditures and other operational requirements.

56

MANAGEMENT OF CORE MATERIALS AFTER
THE ACQUISITION

DIRECTORS

Upon consummation of the Acquisition, the Board of Directors of Core Materials will consist of five members consisting of the following persons: (i) two persons designated by Navistar (the "Navistar Designees"); (ii) two persons designated by the Company's existing Board of Directors (the "Company Designees"); and (iii) one person to be selected by mutual agreement of Navistar and the Company (the "Independent Director"). With respect to vacancies on the initial Board of Directors of Core Materials which exist at any time prior to the first annual meeting of the stockholders of Core Materials following the Closing Date, the Company Designees shall have all requisite authority to act on behalf of Core Materials as a special committee of the Board of Directors to fill vacancies created by the resignation or removal of a Company Designee, and the Navistar Designees shall have all requisite authority to act on behalf of Core Materials as a special committee of the Board of Directors to fill vacancies created by the resignation or removal of a Navistar Designee. The individuals listed in the table below are expected to become members of Core Materials' Board of Directors on the Closing Date. It is anticipated that Mr. Prine will serve as Chairman of the Board of Core Materials immediately following the Acquisition. For organizational purposes Mr. Conte has been appointed as the sole officer and director of Core Materials and will serve as such until the Board of Directors described above is appointed.

                                     and co-founded the Financial Restructuring Group.

COMPENSATION OF DIRECTORS

Effective April 1994, the Company's Board of Directors reduced compensation paid to the Company's Directors to $1 per annum. At its meeting on September 12, 1996, the Board of Directors voted to pay $10,000 to each of its non-employee directors (other than Malcolm Prine and one other director who is a former employee of the Company) in recognition of the fact that they have served on the Board without compensation since April 1994. In addition, the Board authorized the payment of $125,000 to Mr. Prine for

58

his services in connection with negotiating the Acquisition contingent upon the consummation of the Acquisition.

Compensation for the Directors of Core Materials has not yet been established. The level of such compensation will be reviewed annually by Core Materials' Board of Directors with the goal of attracting and retaining qualified Directors. While the level of compensation to be paid to Core Materials' Directors has not yet been established it is anticipated that (1) Directors of Core Materials (other than any Directors who are also employees of Core Materials) will receive compensation in line with that paid to directors of other public companies comparable in size to Core Materials, and (2) any Directors who are also employees of Core Materials will not receive compensation for serving as a Director other than reimbursement for travel and other out-of-pocket expenses.

COMMITTEES OF THE BOARD OF DIRECTORS

Following the Acquisition, the Board of Directors of Core Materials will establish such committees and designate members of such committees as it deems appropriate.

EXECUTIVE OFFICERS

The Company is currently seeking to hire a chief executive officer, a chief financial officer and other senior management for Core Materials. Upon Closing of the Acquisition, if a final determination as to the identity of the chief executive officer has not yet been made, Kenneth M. Schmell, age 48, will be appointed to the office of General Manager and Acting Chief Executive Officer of Core Materials. Mr. Schmell is among the candidates being considered for appointment as Core Materials' chief executive officer currently. Mr. Schmell has served Navistar International Transportation Corp. in various capacities during the past five years, including, most recently, as Plant Manager of Columbus Plastics.

COMPENSATION OF EXECUTIVE OFFICERS

Core Materials currently has no officers other than Mr. Conte and has not yet paid any compensation to any of the individuals listed above. The Board of Directors of Core Materials will rely on a compensation committee composed of non-employee members of the Core Materials Board of Directors to recommend the form and amount of compensation to be paid to the executive officers of Core Materials. For information concerning the compensation paid to the executive officers of the Company for the 1995 fiscal year, see the Company's 1996 Proxy Statement, the relevant portions of which are incorporated by reference into the Company's Form 10-K. See "INCORPORATION BY REFERENCE."

It is anticipated that when the compensation committee meets to determine such compensation, which meeting will not occur until after the Closing Date, the compensation committee will generally adhere to compensation policies which reflect the belief that (i) Core Materials must attract and retain individuals of outstanding ability and motivate and reward such individuals for sustained performance, (ii) a substantial portion of an executive's compensation should be at risk based upon the executive's performance and that of Core Materials and
(iii) within these parameters, levels of compensation should generally be in line with that offered by comparable corporations. On an ongoing basis, the type and amount of compensation to be paid by Core Materials to its officers will be entirely discretionary and within the subjective judgment of the compensation committee.

POSSIBLE GRANT OF SHARES TO EMPLOYEES

Certain of the individuals named above as prospective Directors have discussed the possibility of granting to each employee of Core Materials (other than its executive officers) on the Closing Date one hundred shares of Core Materials Common Stock (representing in the aggregate approximately 42,300 shares based on the number of employees of Columbus Plastics as of October 31, 1996). No final decision or action will be taken until the Core Materials Board of Directors is constituted of the five persons named above.

THE ASSET PURCHASE AGREEMENT

The description of the terms and conditions of the Asset Purchase Agreement included in this Proxy Statement/Prospectus is qualified in its entirety by reference to the Asset Purchase Agreement, a copy of which is attached hereto as Annex I and is incorporated herein by reference.

GENERAL

The Asset Purchase Agreement provides for the acquisition by the Company of substantially all of the assets, properties and business, subject to the assumption of certain liabilities, of Columbus Plastics. In consideration therefor, Navistar will receive upon closing ("Closing") of the Acquisition (1) $25,504,000, subject to adjustment as described below, payable by the Company by delivery of the Secured Note and (2) 4,264,000 shares of Core Materials Common Stock representing approximately 45% of the total number of shares of Core Materials Common Stock issued and outstanding on a fully diluted basis after the Acquisition. The Company may reduce the principal amount of the Secured Note by delivering to Navistar on the date of the Closing (the "Closing Date") by wire transfer of immediately available funds an amount equal to such reduction pursuant to financing arrangements that, in the opinion of the Company and Navistar, would not reasonably be expected to have a material adverse effect on the ability of Core Materials to secure loans for working capital and project finance use after the Closing. The Secured Note will require the Company to pay principal installments as follows: (i) within ninety (90) days after the end of each fiscal year during the term of the Secured Note, the Company will pay principal in an amount equal to the amount, if any, by which the total cash and cash equivalents of the Company, as shown on its audited balance sheet and statement of financial condition for the end of such year, exceed $3,000,000;
(ii) in the event the Company obtains, from time to time, any loan, extension of credit or other financial accommodation (other than a revolving line of

60

credit for working capital purposes or for project finance use) to refinance the Secured Note, the Company will promptly upon obtaining such loan pay principal in an amount equal to the proceeds of such loan; and (iii) if not paid earlier, the Company shall pay the entire outstanding principal amount of the Secured Note in November 2006. The Secured Note will bear interest at the rate of 8.0% per annum, payable semi-annually on the last business day of each May and November. The Secured Note will be secured by a first priority lien upon and security interest in all of the Company's assets. For a more detailed description of the Secured Note, see "--Ancillary Agreements--The Secured Note".

Under the Asset Purchase Agreement, at the Closing, Navistar has agreed to sell, convey, transfer and assign to the Company, and the Company has agreed to purchase from Navistar, all of Navistar's rights, title and interest in the following assets relating exclusively to Columbus Plastics (the "Assets"): (i) all cash and cash equivalents and accounts and notes receivable of Navistar and its affiliates (collectively, the "Navistar Entities") reflected on the Closing Date Balance Sheet, other than intercompany accounts and notes receivable, and all inventory in existence as of the Closing; (ii) all machinery, equipment, vehicles, furniture and fixtures (and all spare parts inventory relating exclusively to any of the foregoing) and other tangible assets (except certain specified excluded assets) (A) located on the real property at 800 Manor Park Drive, Columbus, Ohio and relating primarily to Columbus Plastics or (B) listed or described on a schedule to the Asset Purchase Agreement (collectively, the "Equipment"); (iii) the computer software, data, databases and documentation listed or described on a schedule to the Asset Purchase Agreement; (iv) all contracts, agreements, licenses, mortgages, leases (for both real and personal property), and other agreements or arrangements, whether oral or written, (A) that are listed or described on a schedule to the Asset Purchase Agreement and (B) if not so listed or described, that relate exclusively to Columbus Plastics and are in existence as of the Closing, including all commitments and orders for the purchase and sale of goods and equipment and services (including advertising, maintenance and other incidental services) relating exclusively to Columbus Plastics (collectively, the "Contracts"); (v) all intellectual property
(other than (x) computer software, data, databases and documentation and (y)
other items set forth on a schedule to the Asset Purchase Agreement) relating exclusively to fiberglass and plastic component parts produced by Columbus Plastics or the current manufacture of products (the "Plastics Business Intellectual Property Rights"); (vi) all existing customer and vendor lists, price lists and other business and operational records pertaining to the conduct of Columbus Plastics, including records relating to its third party customers and suppliers; (vii) all right, title and interest in the real property described on a schedule to the Asset Purchase Agreement (which real property is the plant and surrounding grounds owned by Navistar at 800 Manor Park Drive, Columbus, Ohio which is Columbus Plastics' sole place of business) (collectively, the "Real Property"), together with all buildings, fixtures and improvements located thereon; (viii) to the extent transferable, any permits or licenses issued by any governmental agency that are used exclusively in Columbus Plastics; (ix) all prepayments by Navistar relating to the operations of Columbus Plastics to the extent reflected on the Closing Date Balance Sheet; and
(x) all other intangible personal property of whatever kind or character, whether evidenced in writing or not, including current choices in action, claims, causes of action (whether fixed or contingent), and goodwill, owned by Navistar and relating exclusively to the Products and Columbus Plastics, but excluding all such intangible personal property relating to assets or liabilities not transferred to or assumed by the Company pursuant to the Asset Purchase Agreement.

Pursuant to the Asset Purchase Agreement, the Company shall assume on the Closing Date and shall pay, perform and discharge when due the following obligations and liabilities relating to Columbus Plastics, the Products or the Assets absolute or contingent, whether or not accrued, and whether arising before, on or after the Closing Date which are (collectively, together with all other liabilities assumed by the Company pursuant to the Asset Purchase Agreement, the "Assumed Liabilities"): (i) all obligations and liabilities of Navistar under the Contracts (other than, except for liabilities for which reserves have been specifically established on the Closing Date Balance Sheet (but only up to the amount of such reserves), liabilities with respect to claims relating to breaches or alleged breaches of Contracts by Navistar arising prior to the Closing Date); (ii) except as specifically provided in the Supply Agreement, all obligations and liabilities of Navistar for claims, actions, suits or other legal or administrative proceedings made by any person from and after the Closing Date in respect of any and all Products (including inventory) manufactured, formulated, marketed, sold or distributed at any time prior to, on or after the Closing Date (including all obligations and liabilities in connection with the manufacture, formulation, marketing, sale or distribution thereof) in connection with

The Company's obligations with respect to the Assumed Liabilities shall not be subject to offset or reduction by reason of any actual or alleged breach of any representation, warranty or covenant contained in the Asset Purchase Agreement or any agreement or document delivered in connection therewith or any right or alleged right to indemnification thereunder.

Under the Asset Purchase Agreement, the Company and Navistar have agreed that the Company is not assuming any obligations or liabilities of Navistar not specifically provided for in the Asset Purchase Agreement (the obligations and liabilities of Navistar not specifically assumed by the Company being referred to collectively herein as the "Excluded Liabilities"). Notwithstanding anything in the Asset Purchase Agreement to the contrary and without limiting the generality of the foregoing, the Company and Navistar agreed that the Company shall not assume or be liable for any of the following obligations or liabilities: (i) any other obligation or liability of Navistar under the Asset Purchase Agreement and the other agreements with the Company contemplated thereby; (ii) except as otherwise provided in the Asset Purchase Agreement or in the ancillary agreements, any obligation or liability of Navistar for expenses or fees incident to or arising out of the negotiation, preparation, approval or authorization of the Asset Purchase Agreement and the other agreements contemplated thereby or the consummation (or preparation for the consummation) of the transactions contemplated by the Asset Purchase Agreement, including attorneys' and accountants' fees; (iii) except for those expressly accrued for and reflected on the Closing Date Balance Sheet, any obligation or liability of Navistar relating to Columbus Plastics with respect to federal, state, local or foreign income taxes and any liabilities for interest, penalties or additions to any of such income taxes (except income taxes and related liabilities with respect to Columbus Plastics relating to periods from and after the Closing Date and other income taxes and related liabilities specifically allocated to, prorated to or assumed by the Company under the Asset Purchase Agreement); (iv) except for those expressly accrued for and reflected on the Closing Date Balance Sheet or as otherwise provided in the Asset Purchase Agreement, any obligation or liability of Navistar with respect to the Employee Benefit Plans and Multiemployer Plans that Navistar maintains, to which it contributes, or to which it has an obligation to contribute covering employees and former employees of Navistar at Columbus Plastics (collectively, the "Navistar Plans" and individually, a "Navistar Plan"); (v) except for those expressly accrued for and reflected on the Closing Date Balance Sheet, any claim, suit, action or other legal or administrative proceeding based primarily upon an event occurring or a claim arising (x) on or prior to the Closing Date and regardless of whether or not such claim, suit, action or other proceeding is disclosed pursuant to the Asset Purchase Agreement or (y) after the Closing Date but solely in the case of (and to the extent that) such claim, suit, action or other proceeding relates primarily to or arises primarily out of acts or omissions of the Navistar Entities occurring prior to the Closing Date (including, without limitation, any claims relating to a breach or alleged breach of any Contract) other than, in each case as contemplated by clauses (i) or (ii) of the definition of Assumed Liability above; and (vi) any other obligation or liability with respect to or arising out of any Products, the Assets or the conduct of Columbus Plastics prior to the Closing Date that are not Assumed Liabilities.

PURCHASE PRICE ADJUSTMENTS

The Asset Purchase Agreement provides that the purchase price payable on the Closing Date is subject to certain post-closing adjustments as described below.

The Initial Purchase Price Adjustment. If Net Tangible Assets (as defined below) as of the Closing Date exceeds Net Tangible Assets as of January 31, 1996, the amount of such excess shall be paid to Navistar, at Navistar's option by (A) the issuance by the Company to Navistar of additional shares of the Common Stock (valued, for purposes of this adjustment only, at $2.50 per share) provided that the aggregate amount of shares

62

of the Core Materials Common Stock issued to Navistar by the Company pursuant to this adjustment, together with the shares of the Core Materials Common Stock issued to Navistar in the Stock Issuance, may, subject to the Adjustment Based on Closing Date Ownership described below, not exceed 45% of the total number of shares of Core Materials Common Stock issued and outstanding on a fully diluted basis, (B) an increase in the principal amount of the Secured Note, or (C) a combination of (A) or (B) above. If Net Tangible Assets on January 31, 1996 exceeds Net Tangible Assets as of the Closing Date, the principal amount of the Secured Note delivered at the Closing shall be decreased by the amount of such excess. "Net Tangible Assets" means, as of the Closing Date, the amount reflected as (Total Assets minus Intangible Assets) minus (Total Liabilities minus Intangible Liabilities) on the Closing Date Balance Sheet (as defined below), and as of January 31, 1996 means the amount reflected as (Total Assets minus Intangible Assets) minus (Total Liabilities minus Intangible Liabilities) on Navistar's books of Columbus Plastics on such date. Within 45 days after the Closing Date, Navistar shall prepare and deliver to the Company based upon the books and records of Columbus Plastics and consistent with past practices, a balance sheet of Columbus Plastics (including footnotes thereto) (the "Closing Date Balance Sheet"), as of the Closing Date. The Company and its authorized representatives shall be entitled to review the Closing Date Balance Sheet and the books, records and work papers of Navistar used to prepare it and the Asset Purchase Agreement provides procedures for reconciling any points of contention between the Company and the Closing Date Balance Sheet.

The Adjustment Based on Closing Date Ownership. In the event that at any time within three years prior to the Closing any person or Public Group (as defined below) was a Five Percent Stockholder (as defined below) of the Company and the effect of such Five Percent Stockholder(s), together with the issuance of shares of the Core Materials Common Stock to Navistar pursuant to the terms of the Asset Purchase Agreement, would be to cause a 49 Percentage Point Increase (as defined below) (such event being a "Triggering Event"), then the purchase price shall be adjusted, effective as of the Closing, as follows (the "Adjustment Based on Closing Date Ownership"): (A) the principal amount of the Secured Note will be increased by an amount equal to the sum of (x) to the extent that Navistar's ownership of Core Materials Common Stock effective as of the Closing would, on account of the operation of this adjustment, be reduced below 40% of the total shares of Core Materials Common Stock issued and outstanding as of the effective time of Closing, the product derived by multiplying $7.50 times the total number of Excess Shares (as defined in clause (B) below) that, if retained by Navistar, would cause Navistar's ownership of Core Materials Common Stock effective as of the Closing, to equal 40% of the total shares of Core Materials Common Stock issued and outstanding as of the effective time of Closing plus (y) the product derived by multiplying the total number of all remaining Excess Shares times $5.00, and (B) the number of shares of Core Materials Common Stock deliverable to Navistar pursuant to the Asset Purchase Agreement (collectively the "Delivered Shares") shall be reduced by such number of shares (the "Excess Shares") such that the number of shares then deliverable pursuant to the Asset Purchase Agreement when taken together with ownership changes of all Five Percent Stockholder(s) of the Company within the three year period prior to Closing would be one share short of causing a 49 Percentage Point Increase. "Five Percent Stockholder" means any Person or Public Group whose ownership in the Company would cause such person or Public Group to be a "5-percent stockholder" of the Company within the meaning of Treasury Regulations Section 1.382-2T(g)(1)(i) or (ii). "49 Percentage Point Increase" means an increase of 49 percentage points or more of the Stock (as defined below) of the Company owned by Five Percent Stockholders over the lowest percentage of Stock owned by such 5-percent stockholders at any time during the three-year period preceding the Closing, such determination to be made in accordance with Treasury Regulations Section 1.382-2T(c) as if the Closing Date were a "testing date." "Public Group" has the meaning set forth in Treasury Regulations Section 1.382-2T(f)(13). "Stock" means all classes of stock of the Company, all options (as defined in Treasury Regulations Section 1.382-4(d)(g)) to acquire stock of the Company that must be treated as exercised pursuant to Treasury Regulation Section 1.382-4(d)(2) and all other interests that would be treated as stock in the Company pursuant to Treasury Regulations Section 1.382-2T(f)(18)(iii).

Under the Asset Purchase Agreement, the Company agrees to promptly inform Navistar in writing as soon as it becomes aware of any facts or circumstances which may bear upon the existence of a Five Percent Stockholder and/or 49 Percentage Point Increase. Navistar's determination at any time as to the existence of a Five Percent Stockholder and/or 49 Percent Point Increase, the occurrence of a Triggering Event and the

63

calculation of the Adjustment Based on Closing Date Ownership, based on the facts and circumstances known to it at such time, shall be binding on the parties (such determination by Navistar, as from time to time revised by Navistar, is herein the "Closing Date Ownership Determination"). Navistar shall promptly notify the Company in writing of any Closing Date Ownership Determination, which notice shall set forth, in reasonable detail, Navistar's basis for determining the occurrence of a Triggering Event and the calculation of the Adjustment Based on Closing Date Ownership (a "Notice of Closing Date Ownership Determination"). In the event that a Triggering Event is determined to exist pursuant to a Notice of Closing Date Ownership Determination (regardless of whether such Notice is given before or after Closing and whether one or more other Notices of Closing Date Ownership Determination have previously been given), the Adjustment Based on Closing Date Ownership in respect of such Triggering Event shall be effective as of the Closing based on the ownership of Stock as of the time of Closing as determined pursuant to such Notice. Notwithstanding anything herein to the contrary, no further Notice of Closing Date Ownership Determination shall be given by Navistar after March 31, 1997 ("Outside Notice Date"), so that the Closing Date Ownership Determination as in existence on the Outside Notice Date and the Adjustment Based on Closing Date Ownership pursuant to such Determination shall be final and binding on the parties. Prior to the Outside Notice Date, neither Navistar nor any transferee of the Delivered Shares shall transfer any of the Delivered Shares other than to persons who agree to take the Delivered Shares subject to the provisions of the Adjustment based on Closing Date Ownership (for which purpose, Excess Shares at any time shall first be reduced from any remaining Delivered Shares then held by Navistar and/or its affiliates, and thereafter shall be reduced from any Delivered Shares then held by transferees on a pro rata basis).

Contingent Earn-Out. If the Company's earnings before interest and taxes ("EBIT") for the Company's fiscal year ended December 31, 1997 exceed $6,512,000 ("Forecasted EBIT"), an amount equal to the product of (x) the excess amount ("1997 Excess EBIT") multiplied by (y) 5.55 shall be paid to Navistar by an increase in the principal amount of the Secured Note. If the Company's EBIT for the Company's fiscal year ended December 31, 1998 exceeds Forecasted EBIT, an amount equal to the product of (x) the excess amount ("1998 Excess EBIT") less the 1997 Excess EBIT multiplied by (y) 4.50 shall be paid to Navistar by an increase in the principal amount of the Secured Note. If the Company's EBIT for the Company's fiscal year ended December 31, 1999 exceeds the Forecasted EBIT, an amount equal to the product of (x) the excess amount less the 1998 Excess EBIT multiplied by (y) 2.75 shall be paid to Navistar by an increase in the principal amount of the Secured Note. For purposes of this adjustment, the Company's EBIT shall be calculated using the same methodology and based on the same types and categories of expenses as used in the calculation of Forecasted EBIT, and shall expressly exclude any and all other types or categories of expenses. Notwithstanding anything herein to the contrary, the total amount by which the principal amount of the Secured Note may be increased pursuant to this adjustment shall not exceed $24,496,000 in the aggregate. This contingent earn-out adjustment will be accounted for by increasing the amount of the Secured Note and reducing the amount of Core Materials' retained earnings.

Within 90 days after the close of each such fiscal year, the Company shall prepare and deliver to Navistar based on the books and records of the Company an audited balance sheet and statement of income for such fiscal year prepared in accordance with generally accepted accounting principles, together with a certificate ("EBIT Certificate") dated as of the end of such fiscal year and signed by the chief financial officer of the Company certifying the amount of the Company's EBIT for such fiscal year, the amount of any excess over Forecasted EBIT and the amount to be paid to Navistar pursuant to the adjustment described above. Navistar and its authorized representatives shall be entitled to review the EBIT Certificate and the books, records and work papers of the Company used to prepare it, and the Asset Purchase Agreement provides procedures for reconciling points of contention between the Company and Navistar with respect to the EBIT Certificate.

REPRESENTATIONS AND WARRANTIES; CONDITIONS TO CLOSING; AMENDMENTS; TERMINATION

The Asset Purchase Agreement contains certain representations and warranties by Navistar and the Company which will expire at, and not survive, the Closing. Each party's obligation to consummate the Acquisition is subject to a number of conditions, including, among other things, the receipt of satisfactory legal opinions, the accuracy of their respective representations and warranties as of the Closing Date, receipt by the parties of all third party, stockholder and governmental consents and approvals required to consummate the

64

Acquisition and the other transactions contemplated by the Asset Purchase Agreement, the execution and delivery by Navistar and the Company of the Supply Agreement, the Transition Services Agreement and the Registration Rights Agreement (each as defined below), and the Company and International Association of Merchants and Aerospace Workers ("IAM") entering into a collective bargaining agreement for the employment of IAM represented employees of the Company at Columbus Plastics and compliance by all parties with their respective obligations prior to the Closing Date. The obligation of the Company to consummate the Acquisition is also subject to the approval of the Company's stockholders of the transactions contemplated by the Asset Purchase Agreement, including the approval of the Merger Agreement by the affirmative vote of no less than two-thirds of the Company Common Stock present and entitled to vote at the Special Meeting and receipt of the opinion of Nomura to the effect that the consideration to be paid by the Company pursuant to the Asset Purchase Agreement is fair to the stockholders of the Company from a financial point of view. The obligation of Navistar to consummate the Acquisition is also subject to the consummation of the Merger, the Company having terminated the RYMAC Salary Reduction Simplified Employee Pension Plan ("SEP") in accordance with applicable law, Core Materials having a charter and by-laws satisfactory to Navistar, the Company having registered under the Securities Act, and having obtained approval for listing on the American Stock Exchange of, the shares of Core Materials Common Stock to be issued to Navistar under the Asset Purchase Agreement, each of the individuals serving on the Company's Board of Directors tendering his or her resignation to the Company effective as of the Closing Date.

Any provision of the Asset Purchase Agreement may be amended or waived prior to the Closing; provided that any such amendment or waiver shall be binding upon Navistar only if set forth in a writing executed by Navistar and referring specifically to the provision alleged to have been amended or waived, and any such amendment or waiver shall be binding upon the Company only if set forth in a writing executed by the Company and referring specifically to the provision alleged to have been amended or waived. No course of dealing between or among any persons having any interest in the Asset Purchase Agreement shall be deemed effective to modify, amend or discharge any part of the Asset Purchase Agreement or any rights or obligations of any person under or by reason of the Asset Purchase Agreement.

The Asset Purchase Agreement provides that it may be terminated and the transactions contemplated thereby abandoned at any time prior to the Closing Date: (i) by the mutual written consent of Navistar and the Company; (ii) by Navistar if (y) at any time after October 31, 1996 any of the conditions to Closing summarized above (other than those conditions which relate solely to the obligations of the Company to consummate the Acquisition) shall have become incapable of fulfillment, and shall not have been waived by Navistar, or (z) the Company shall not have delivered to Navistar by September 30, 1996 copies of the resolutions adopted by the Company's Board of Directors authorizing the execution, delivery and performance of the Asset Purchase Agreement and the other agreements and transactions contemplated thereby that are in form and substance reasonably satisfactory to Navistar ("Company Resolutions"); (iii) by the Company if (y) at any time after October 31, 1996 any of the conditions to Closing summarized above (other than those conditions which relate solely to the obligations of Navistar to consummate the Acquisition) shall have become incapable of fulfillment, and shall not have been waived by the Company, or (z) Navistar shall not have delivered to the Company by September 30, 1996 copies of the resolutions adopted by the Navistar's Board of Directors authorizing the execution, delivery and performance of the Asset Purchase Agreement and the other agreements and transactions contemplated thereby that are in form and substance reasonably satisfactory to the Company; (iv) by Navistar or the Company if the Closing does not occur on or prior to December 31, 1996; provided, however, that the party seeking termination pursuant to clause (ii) or
(iii) above (other than clause (ii)(y) or (iii)(y) above) is not in breach of any of its representations, warranties, covenants or agreements contained in the Asset Purchase Agreement, which breach has resulted in the failure of a condition to Closing.

CERTAIN COVENANTS

The Company agrees that Navistar shall not have any liability whatsoever to the Company arising out of or relating to the failure to obtain any consents that may have been or may be required in connection with the transactions contemplated by the Asset Purchase Agreement or because of the default, acceleration or termination of any Contract as a result thereof. At the Company's written request prior to the Closing,

65

Navistar shall cooperate with the Company in any reasonable manner in connection with the Company's obtaining any such consents; provided, however, that such cooperation shall not include any requirement of the Navistar Entities to expend money, commence any litigation or offer or grant any accommodation (financial or otherwise) to any third party. With respect to any Contracts that may not be properly assigned to the Company because of the failure to obtain a required consent ("Nontransferable Contracts") with respect to which the Company has requested Navistar's cooperation and with respect to which Navistar and the Company are unable to obtain a separate agreement between the Company and the other party or parties, the Company shall have the right to require that Navistar use reasonable efforts to perform any such Nontransferable Contract, to the extent it relates to Columbus Plastics, as agent for and for the account of the Company and shall promptly remit any such funds collected for the account of the Company, for a period up to six months following the Closing Date; provided that the Company shall reimburse Navistar (on behalf of itself and as agent for the other Navistar Entities) for any and all costs, expenses, losses and liabilities incurred by the Navistar Entities in connection with taking such action.

Each of the parties to the Asset Purchase Agreement has agreed to cooperate with each other and to cause their respective officers, employees, agents and representatives to cooperate with each other for a period of 60 days after the Closing to provide for an orderly transition of the Assets and the Assumed Liabilities to the Company and to minimize the disruption to the respective businesses of the parties resulting from the transactions contemplated by the Asset Purchase Agreement; provided, no party shall be required to take any action that would unreasonably interfere with the conduct of its business.

The Company has agreed to offer to employ those employees of Navistar who are currently employed by Navistar at Columbus Plastics and who are not represented by a union, including such employees who are absent from active employment for any reason as of the Closing Date. All such employees who become the Company's employees effective on the Closing Date are referred to herein as the "Hired Employees". The Company has agreed to employ the Hired Employees at the same salary and wages, and with the benefits that are identical in all material respects, as provided by Navistar immediately prior to the Closing Date; provided, however, that the Company shall not be required to establish or maintain any Employee Welfare Benefit Plan (as defined in the Asset Purchase Agreement) for any Hired Employee that provides postretirement medical, dental or life insurance benefits. Nothing in the Asset Purchase Agreement limits the Company's right, at any time, to modify, amend or terminate any salary and wages payable, or benefit provided, to any or all Hired Employees on or after the Closing Date, including without limitation any Employee Welfare Benefit Plan or any Employee Pension Benefit Plan (as defined in the Asset Purchase Agreement), to the extent permitted by law. Navistar assumes all liability for and shall indemnify, defend and hold the Company harmless from and against any Losses (as defined below under "--The Asset Purchase Agreement--Survival of Representations and Warranties; Indemnification") for any severance liability with respect to employees of Navistar as of the Closing Date under the terms of any severance policy, practice or plan of Navistar, which liability is triggered by or results from Navistar's termination of each such employee's employment with Navistar effective as of the Closing Date, without regard to whether any such employee accepts employment with the Company.

The Company has agreed to negotiate a collective bargaining agreement with the IAM for the employment of IAM-represented employees by the Company at Columbus Plastics. In the Asset Purchase Agreement, Navistar and the Company recognize that certain IAM-represented employees of Navistar who are on the Closing Date eligible to receive a pension benefit other than a deferred vested benefit (or would be eligible to receive such pension benefit if they did not accept employment in a position covered by the IAM Multiemployer Plan) will be eligible for postretirement benefits under the Navistar International Transportation Corp. Retirement Health Benefit and Life Insurance Plan which was established by Navistar pursuant to Shy v. Navistar. The Company has agreed to reimburse Navistar for its cost of such coverage for any IAM represented employees hired by the Company on a pro rata basis based on the time of service with the Company compared to the total time of service with Navistar and the Company. Other than Shy postretirement benefits for retirement-eligible employees, the Company has agreed to assume all liability for any postretirement benefit liability arising from the transactions contemplated by the Asset Purchase Agreement or the employment of any IAM-represented employee hired by the Company, and Navistar will not assume any such liability or reimburse the Company for any amount of such liability. In the event that Navistar is liable for any amount for which the Company is not also liable for any postretirement benefit for

66

any IAM-represented employee hired by the Company, the Company has agreed to reimburse Navistar for a pro rata portion of Navistar's liability based on the time of the employee's service for the Company compared to the total time of service with Navistar and the Company. If the Company's collective bargaining agreement with the IAM provides for the establishment of a Section 401(k) plan for the employees subject to the agreement, the agreement shall permit, and the Company shall cause its Section 401(k) plan to accept, a trust-to-trust transfer of the assets and liabilities (including participant loans and amounts payable to alternate payees under qualified domestic relations orders, but not including any in-kind transfer of any Navistar International Corporation stock) of Navistar's Section 401(k) plan, with respect to the IAM-represented employees hired by the Company, valued as of such date as Navistar may reasonably determine. The Company has agreed to establish its Section 401(k) plan timely and in a form meeting the qualification requirements of the Code and provide such evidence to Navistar as Navistar may reasonably request as to such qualification so as to permit Navistar to transfer timely the assets and liabilities relating to the IAM-represented employees hired by the Company.

The Company has agreed to comply with the requirements of Section 4204 of ERISA with respect to each Multiemployer Plan (as defined in the Asset Purchase Agreement) that Navistar maintains, to which it contributes, or to which it has an obligation to contribute covering employees and former employees of Navistar at Columbus Plastics and, in that regard, the Company has agreed to (A) contribute to each such Multiemployer Plan with respect to the operations of the Company for substantially the same contribution base units (as set forth in the collective bargaining agreement in effect immediately prior to the Closing Date between Navistar and the IAM) for which Navistar had an obligation to contribute to each such Multiemployer Plan; (B) provide to each such Multiemployer Plan for a period of five years commencing with the first plan year beginning after the Closing Date a bond or other security as described in Section 4204(a)(1)(B) of ERISA (unless such requirement has been released or waived in accordance with procedures consistent with Section 4204 of ERISA), which security, if provided, will be paid to a Multiemployer Plan if the Company withdraws from the Multiemployer Plan or fails to make a contribution to the Multiemployer Plan when due at any time during the first five years beginning after the Closing Date; and (C) pay when due any withdrawal liability assessed as a result of any complete or partial withdrawal by the Company during the five-year period calculated in accordance with Section 4204(b)(1) of ERISA. Navistar has agreed that if, during the first five plan years beginning after the Closing Date, the Company withdraws in a complete or partial withdrawal, Navistar will be secondarily liable for any withdrawal liability it would have had to the Multiemployer Plan with respect to Navistar's operations as of the Closing Date but for the provisions of the Asset Purchase Agreement described above. Upon its dissolution or liquidation, Navistar has agreed to provide each Multiemployer Plan referred to in the first sentence of this paragraph with such security as is required pursuant to Section 4204(a)(3)(A) of ERISA, unless a release or waiver of such security shall be granted by the Multiemployer Plan or the PBGC consistent with the requirements of Section 4204(a)(3)(A) of ERISA. For purposes of the immediately preceding sentence, the term "Navistar" means the Navistar and any of its affiliates which meet the definition of "single employer" for purposes of Section 3(37) of ERISA. Navistar and the Company have agreed to take all actions necessary or desirable to assure that no withdrawal liability arises with respect to each such Multiemployer Plan by reason of the transactions contemplated by the Asset Purchase Agreement.

Navistar has agreed to retain all assets of, and liabilities under, the Navistar Plans relating to non-represented employees, and no such Navistar Plan or any assets or liabilities thereof shall be transferred to, or assumed by, the Company. The Company has agreed to establish Employee Benefit Plans (as defined in the Asset Purchase Agreement) to cover the Hired Employees as of the Closing Date that are identical in all material respects to the Navistar Plans that covered the Hired Employees immediately prior to the Closing Date; provided, however, that the Company shall not be obligated under the Asset Purchase Agreement to establish or maintain any Employee Welfare Benefit Plan for the benefit of the Hired Employees that provides postretirement medical, dental or life insurance benefits. The Company has no obligation to establish any "New Hire Plans" for any Hired Employee, or any provisions of Navistar Plans that specifically relate to "New Hires". "New Hire Plans" means plans for employees first hired by Navistar International Transportation Corp. or an affiliate within the meaning of Section 414 of the Code on or after January 1, 1996, and "New Hires" means an employee first hired by Navistar International Transportation Corp. or an affiliate within the meaning of Section 414 on or after January 1, 1996. The Company has agreed to cause its Section 401(k) plan

67

to accept a trust to trust transfer of the assets and liabilities (including participant loans and amounts payable to alternate payees under qualified domestic relations orders, but not including any in kind transfer of Navistar International Corporation stock) of Navistar's Section 401(k) plan with respect to the Hired Employees, valued as of such date as Navistar may reasonably determine. The Company has agreed to establish its Section 401(k) plan timely and in a form meeting the qualification requirements of the Code and provide such evidence to Navistar as Navistar may reasonably request as to such qualification so as to permit Navistar to transfer timely the assets and liabilities relating to the Hired Employees.

The Company has agreed to waive pre-existing condition requirements, evidence of insurability provisions, waiting period requirements or any similar provisions under any Employee Benefit Plan or compensation arrangements maintained or sponsored by or contributed to by the Company for each Hired Employee after the Closing Date.

The Company has agreed to apply toward any deductible requirements and out-of-pocket maximum limits under the Company's Employee Welfare Benefit Plans any amounts paid (or accrued) by each Hired Employee under Navistar Plans that are Employee Welfare Benefit Plans during the current plan year.

Navistar and Navistar Plans shall be responsible for expenses covered by Navistar's medical plans; provided, however, that such expenses were incurred prior to the Closing Date. The Company and the Company's plans shall be responsible for expenses covered by the Company's medical plans for all health and accident claims relating to the Hired Employees (including, without limitation, claims arising out of medical conditions existing at or prior to the Closing Date) and all Incidents (as defined below) relating to the Hired Employees that occur or arise on or after the Closing Date. For purposes of the immediately preceding sentence, the term "Incidents" includes accident, death, disabilities, diseases and injuries. Navistar and the Company recognize that certain Hired Employees who become entitled to a pension benefit other than a deferred vested benefit under the Navistar International Transportation Corp. Retirement Plan for Salaried Employees are eligible for postretirement benefits under the Navistar International Transportation Corp. Retirement Health Benefit and Life Insurance Plan which was established by Navistar pursuant to Shy v. Navistar. The Company has agreed to reimburse Navistar for its cost of such coverage of each such Hired Employee on a pro rata basis based on the time of service with the Company compared to the total time of service with Navistar and the Company. Other than the Shy postretirement benefits for such Hired Employees, the Company assumes all liability for the postretirement benefit liability arising from this transaction or the employment of any Hired Employee, and Navistar will not assume any such liability or reimburse the Company for any amount of such liability. The Company has agreed to establish and maintain, or will maintain, any plan or plans necessary to satisfy such liability. In the event that Navistar is liable for any amount for which the Company is not also liable for any postretirement benefit for any Hired Employee, the Company has agreed to reimburse Navistar for a pro rata portion of Navistar's liability based on the time of the employee's service for the Company compared to the total time of service with Navistar and the Company.

Under the Asset Purchase Agreement, Navistar has agreed that it shall be responsible for satisfying obligations under Section 601 et seq. of ERISA and
Section 4980B of the Code, to provide continuation coverage to or with respect to any employee of Navistar as of the Closing Date in accordance with applicable law with respect to any "qualifying event" occurring on or prior to the Closing Date, including any "qualifying event" resulting from the Closing hereunder. The Company shall be responsible for satisfying obligations under Section 601 et seq. of ERISA and Section 4980B of the Code, to provide continuation coverage to or with respect to any Hired Employee in accordance with applicable law with respect to any "qualifying event" which occurs after the Closing Date.

Navistar shall be responsible for all salary accrued but not yet paid as of the Closing Date nor reflected on the Closing Date Balance Sheet and, if applicable, 1996 bonus accrued but not yet paid as of the Closing Date nor reflected on the Closing Date Balance Sheet (in an amount equal to the pro rata portion of such bonus allocable to the period prior to the Closing Date) with respect to the Hired Employees, and the Company shall be responsible for the pro rata portion of such bonus allocable to the period on and after the Closing Date.

Navistar shall pursuant to Article II of the Navistar International Transportation Corp. Income Protection Plan (the "IPP") extend eligibility for pension grow-in to each Hired Employee to the extent such employee would be eligible for pension grow-in under the IPP if such employee were not hired by the

68

SURVIVAL OF REPRESENTATIONS AND WARRANTIES; INDEMNIFICATION

The representations and warranties in the Asset Purchase Agreement and in any schedules delivered in connection therewith expire at, and do not survive, the Closing.

Navistar has agreed under the Asset Purchase Agreement to indemnify the Company, its affiliates and each of their respective officers, directors, employees and agents and hold them harmless from any Loss (as hereinafter defined) suffered or incurred by any such indemnified party or to which any such indemnified party becomes subject to the extent directly or indirectly arising from (i) any breach of (or in the event any third party alleges facts that if true would mean Navistar has breached) any covenant of Navistar contained in the Asset Purchase Agreement or the other agreements and instruments contemplated thereby, (ii) any Excluded Liabilities and (iii) any statements or information contained in this Proxy Statement/Prospectus relating to Columbus Plastics or Navistar or its related entitles requested by the Company for inclusion in this Proxy Statement/Prospectus and supplied by Navistar, provided the Company presents such information in conformity in form and substance with the information supplied to it by Navistar. The Company has agreed under the Asset Purchase Agreement to indemnify each of Navistar, its affiliates, officers, directors, employees and agents against and hold them harmless from any Loss suffered or incurred by any such indemnified party or to which any such indemnified party becomes subject to the extent directly or indirectly arising from (i) any breach of (or in the event any third party alleges facts that if true would mean the Company has breached) any covenant of the Company contained in the Asset Purchase Agreement or the other agreements and instruments contemplated thereby, (ii) any Assumed Liabilities and (iii) any discontinuance, suspension or modification of any benefit plans maintained by the Company as contemplated by the Asset Purchase Agreement. The Company has also agreed to indemnify each of Navistar, its affiliates, officers, directors, employees and agents against and hold them harmless from its Proportionate Share (as defined below) of any Loss suffered or incurred by the Company or any of its subsidiaries from and after the Closing Date (including Losses suffered or incurred by the Company to its present or former stockholders) (x) in respect of any actions, omissions, events, circumstances or state of facts existing or arising on, at or prior to the Closing Date or (y) arising in connection with any statements or information contained in this Proxy Statement/Prospectus (other than information relating to Columbus Plastics or the Navistar Entities requested by the Company for inclusion in this Proxy Statement/Prospectus and supplied by Navistar, provided the Company presents such information in this Proxy Statement/Prospectus in conformity in form and substance with the information supplied to it by Navistar); provided no indemnity will be made by the Company in respect of (i) except as provided in clause (y), any actions, omissions, events, circumstances or state of facts existing or arising on, at or prior to the Closing Date relating to the Asset Purchase Agreement, the matters referred to in the Company Resolutions (other than the ancillary agreements) or any of the transactions contemplated thereby, (ii) any Loss suffered or incurred by the Company or any of its subsidiaries from and after the Closing Date that arises from certain specifically listed liability or (iii) any inability of the Company to be able to use its NOLs for federal income tax purposes after the Closing. For purposes hereof, at the time of any Loss, the "Proportionate Share" of each of Navistar, its affiliates, officers, directors, employees and agents shall be the ratio, expressed as a percentage, of the total number of shares of the Common Stock owned by such person at the time of such Loss divided by the total number of shares of the Common Stock issued and outstanding at the time of such Loss. "Loss" means, with respect to any person, any damage, injury, liability, demand, claim, action, cause of action, cost, deficiency, tax, penalty, fine or other loss, payment or expense, whether or not arising out of a claim, including all interest, penalties, reasonable attorneys' fees and expenses and all amounts paid or incurred in connection with any action, demand, proceeding, investigation or claim by any third party (including any government entity) against or affecting such person, together with interest thereon from the date on which such person provides the written notice of the related claim through and including the date on which the total amount of the claim, including such interest, is recovered or recouped pursuant to the indemnity provisions of the Asset Purchase Agreement.

If an indemnification obligation under the Asset Purchase Agreement arises in respect of any adjustment which results in any tax benefit to the Company or Navistar (the "Benefitted Party"), any successor thereto or any affiliate thereof for any taxable period (or portion thereof) beginning and ending after the Closing Date which would not, but for such adjustment, be available, the Benefitted Party shall pay, or shall cause to be paid, to the party making such indemnification payment an amount equal to the actual tax saving produced by

70

such tax benefit at the time such tax saving is realized by the Benefitted Party, any successor thereto or any affiliate thereof. The amount of any such tax saving for any taxable period shall be the amount of the reduction in taxes payable to a taxing authority by the Benefitted Party, any successor thereto or any affiliate thereof with respect to such tax period as compared to the taxes that would have been payable to a taxing authority by the Benefitted Party, any successor thereto or any affiliate thereof with respect to such tax period in the absence of such tax benefit.

The indemnification obligations under the Asset Purchase Agreement terminate on the sixth anniversary of the Closing Date; provided, however, that such obligations to indemnify and hold harmless shall not terminate with respect to any item as to which the Person to be indemnified or the related party thereto shall have, prior to the sixth anniversary of the Closing Date, previously made a claim by delivering a written notice (stating in reasonable detail the nature of, and factual and legal basis for, any such claim for indemnification, and the provisions of the Asset Purchase Agreement upon which such claim for indemnification is made) to the indemnifying party.

ANCILLARY AGREEMENTS

THE SECURED NOTE

The description of the terms of the Secured Note included in this Proxy Statement/Prospectus is qualified in its entirety by reference to the Form of Secured Note, a copy of which is attached hereto as Annex III and is incorporated herein by reference.

Core Materials intends to enter into a senior credit facility to provide working capital and for other purposes prior to or simultaneous with the consummation of the Acquisition. The lender under such senior credit facility may require changes to the terms of the Secured Note as a condition to entering into the facility. Therefore, the terms of the Secured Note when executed may vary from that contained in the Form of Secured Note attached as Annex III to this Proxy Statement/Prospectus, the provisions of which are described below.

Certain terms used in the description of the Secured Note provided below are used herein as defined under the caption "Definitions" below.

General

Pursuant to the Secured Note, Core Materials will agree to pay to Navistar the principal sum of $25,504,000 with interest on the unpaid principal balance thereof from the date of the Secured Note at the rate of 8.0% per annum (computed on the basis of a 360-day year and the actual number of days elapsed in any year). The principal amount of the Secured Note is subject to adjustment based upon the post-Closing adjustments provided in the Asset Purchase Agreement. See "--The Asset Purchase Agreement--Purchase Price Adjustments." Core Materials will pay principal installments on the Secured Note as follows:
(i) within ninety (90) days after the end of each fiscal year during the term of the Secured Note, Core Materials will pay principal in an amount equal to the amount, if any, by which the total cash and cash equivalents of Core Materials, as shown on its audited balance sheet and statement of financial condition for the end of such year, exceed $3,000,000; (ii) in the event Core Materials obtains, from time to time, any Refinancing Loan, Core Materials will promptly upon obtaining such loan pay principal in an amount equal to the proceeds of such loan; or (iii) if not sooner paid, Core Materials will pay the entire principal amount of the Secured Note in full in November 2006 (the "Maturity Date").

Interest on the Secured Note will be payable semi-annually on the last business day of each May and November. On the date of any scheduled interest payment Core Materials may, subject to certain conditions, elect to add such interest payment to the outstanding principal balance of the Secured Note. Unless prohibited under applicable law, any accrued interest which is not paid on the date on which it is due and payable will bear interest at the same rate at which interest is then accruing on the principal amount of the Secured Note until such interest is repaid. Any accrued interest which for any reason has not therefore been paid shall be paid in full on the date on which the final principal payment on the Secured Note is made.

Core Materials may (at its option), without premium or penalty, at any time and from time to time, prepay all or any portion (in whole number multiples of $50,000) of the outstanding principal amount of the Secured Note, together with accrued interest thereon, provided that Core Materials has paid all interest on the Secured Note through the immediately preceding scheduled interest payment date.

In addition to all other rights and remedies available to Navistar under the Secured Note or otherwise, Navistar will have the right, after the occurrence and during the continuance of any Default or Event of Default, to setoff against and to apply to the accrued and unpaid interest and outstanding principal balance of the Secured Note (in each case, to the extent then due and payable), any obligation owing by Navistar to Core Materials. Any such setoff will be applied first to the payment of interest which is due and payable and only thereafter to the outstanding principal balance of the Secured Note. A setoff of less than all of the outstanding principal amount of the Secured Note shall be applied to the scheduled payments of the outstanding principal amount of the Secured Note in the inverse order of maturity.

The Secured Note will be secured by a first priority lien upon and a security interest in all of Core Materials' assets, whether owned at the time of issuance of the Secured Note or thereafter acquired, and will be entitled to the benefits of the Security Documents. Notwithstanding the foregoing, Noteholder agrees that it will (if requested to do so by the holder of the Senior Obligations), upon terms reasonable acceptable to

72

Noteholder, subordinate its security interest and lien in the Collateral (as defined in the Security Documents) in connection with and to the extent reasonably required to facilitate a Refinancing Loan, and promptly upon the request of the holder of the Senior Obligations, it will execute and deliver such documents, instruments and agreements as are necessary to evidence such subordination.

Under the Secured Note, Core Materials will agree to comply with certain covenants relating to the payment of its obligations, the compliance with applicable laws, the conduct of its business, the maintenance of its property and insurance thereon, the inspection of Core Materials' property, the maintenance of books and records, and the delivery of financial information and notices to Navistar. In the Secured Note, Core Materials will agree to use its best efforts to obtain a Refinancing Loan within six months from the date of the Secured Note in amounts and with terms reasonably satisfactory to Core Materials and the Noteholder.

If any Event of Default has occurred (other than the type described under subparagraph (vi) above), the Noteholder may declare all or any portion of the outstanding principal amount of the Secured Note (together with all accrued interest thereon and all other amounts due and payable with respect thereto) to be immediately due and payable and may demand immediate payment of all or any portion of the outstanding principal amount of the Secured Note (together with all such other amounts then due and payable).

77

The Noteholder shall also have any other rights which such holder may have been afforded under any contract or agreement (including, without limitation, the Security Documents) at any time and any other rights which such holder may have pursuant to applicable law.

Amendment and Waiver

Except as otherwise expressly provided herein, the provisions of the Secured Note may be amended and Core Materials may take any action herein prohibited, or omit to perform any act herein required to be performed by it, only if Core Materials has obtained written consent of the Noteholder.

THE SUPPLY AGREEMENT

General

As a condition to the consummation of the Acquisition, Navistar and Core Materials will enter into the Comprehensive Supply Agreement (the "Supply Agreement"). Under the terms of the Supply Agreement, for a period of five years, Navistar will agree to purchase from Core Materials, and Core Materials will agree to sell to Navistar, all of Navistar's original Products. The Supply Agreement is intended to be a rolling five year agreement where an extension to the fifth year is negotiated annually.

On a pro forma basis, pursuant to the terms of the Supply Agreement, Navistar would have paid $43.6 million and $27.1 million to Core Materials in the year ended October 31, 1995 and the nine months ended July 31, 1996, respectively. However, no minimum quantities of annual production of Products or minimum purchase quantities are set forth or implied in the Supply Agreement, and no penalties will be imposed on Navistar for volumes of products actually ordered by Navistar below those quantities forecasted. In addition, Navistar is not required to purchase any new products from Core Materials other than the Products covered by the Supply Agreement, unless in Navistar's opinion Core Materials is competitive in price, performance, delivery, reliability, technology and quality with other manufacturers of any such products. In addition, during the term of the Supply Agreement, Core Materials agrees that it will not manufacture or sell the products covered by the Supply Agreement and developed exclusively for Navistar to any other party other than Navistar, unless authorized in writing by Navistar. In the Supply Agreement, Core Materials will agree to quality, packaging and other Navistar specifications in manufacturing and delivery of the Products.

Warranty

Under the Supply Agreement, Core Materials agrees to warrant its products for Navistar's heavy duty, medium duty and school bus chassis which prove to be defective in material and/or workmanship of Core Materials' products up to twelve (12) months from the new vehicle delivery date to user or 100,000 miles.

81

Support Services

Pursuant to the Asset Purchase Agreement Core Materials will provide at no additional cost to Navistar such design and design qualification assistance, manufacturing assistance, technical and field support as may be reasonably required by Navistar.

Indemnification

Core Materials will agree to indemnify and hold harmless Navistar and its officers, directors and affiliates from any and all damages, costs and expenses incurred as a result of a claim by any third party regarding any harm, damage or loss incurred (or alleged to have incurred) as a direct result of any defect in the materials or workmanship of Core Materials' products. Navistar will agree to indemnify and hold harmless Core Materials and its officers, directors and affiliates from any and all damages, costs and expenses incurred as a result of a claim by any third party regarding any harm, damage, loss or expense incurred (or alleged to have incurred) as a result of Navistar's installation of Core Materials' products other than as a direct result of any defect in the materials or workmanship of Core Materials' products.

Failure to Stay Competitive

If Navistar reasonably demonstrates to Core Materials that a particular Product is no longer a competitive value with respect to price, performance, delivery, reliability, technology and quality with other equivalent products then available, then Core Materials will have sixty (60) days of such demonstration to cure the deficiency. If Core Materials cannot remedy the situation within such sixty (60) days, Navistar may at its option terminate the obligations of the parties under the Supply Agreement with respect to the non-competitive Products.

Reimbursement for Non-Performance

In the Supply Agreement, the parties acknowledge that the precise amount of damages which Navistar would sustain in the event Core Materials were to fail to make timely or conforming deliveries of Products would be difficult to determine. Therefore, the parties agree that Core Materials shall be responsible for consequential or incidental damages for the correction of Products assembled out of sequence, as a result of delivery delays by Core Materials that are not due to circumstances beyond its control, such as weather, transportation system failures or other acts of God, or for the correction of Products with quality problems by making a payment of $66 per manhour required to correct such problems. Any costs Navistar incurs in connection with Navistar's assembly line down time caused by the failure of Core Materials to deliver on schedule, for reasons not beyond its control but only to the extent that Navistar is not covered by business interruption insurance, will be charged at a rate of $700 per minute. Core Materials will advise Navistar immediately in writing of any apparent imminent problem and the parties will mutually use their best efforts to avoid any actual assembly line down time. Core Materials shall not be responsible for the above damages if such out-of-order (late) delivery or non-delivery results from a cause beyond Core Materials' reasonable control without fault or negligence, provided that Core Materials has immediately informed Navistar in writing of the problem. It is expressly understood that a failure by Core Materials to perform resulting from a strike, lockout or labor difficulty of Core Materials shall not be excused, and Core Materials shall be responsible for the above damages, except if Core Materials shall promptly notify Navistar in writing of any anticipated labor dispute or labor shortage or any other labor performance interruption, and Core Materials shall arrange for advance deliveries or warehousing, at Navistar's option and at locations acceptable to Navistar, of a one month supply of Products, or other quantity mutually agreed upon.

Material, Labor and Overhead

Labor and overhead costs will be firm, and only raw material adjustments will be made for the duration of the Supply Agreement. Price adjustments for raw materials will be based on actual transaction prices and must be verified by actual sub-supplier invoices.

82

Intellectual Property Indemnity

In the Supply Agreement Core Materials will agree to defend, at its expense, any claim or suit against Navistar or Navistar's customers, based on an assertion or claim that a Product furnished by Core Materials to Navistar pursuant to the Supply Agreement or the use or sale by Navistar or its customers in the manner contemplated by the Supply Agreement infringes any patent or copyright or is a wrongful use of third-party trade secret or proprietary information, and further agrees to indemnify and hold Navistar harmless from any cost and expenses, including attorneys' fees, settlements associated with said claim or suit, or any damages, including attorneys' fees or costs, finally awarded in any such suit, provided that Core Materials is notified promptly in writing of the suit or claim and, at Core Materials' request and expense, is given control of the defense to such claim or suit and all reasonable assistance for the defense of same. If the use or sale of a Product furnished under the Supply Agreement is enjoined as a result of such suit, Core Materials, at its option and at no expense to Navistar, shall obtain for Navistar and its customers the right to use and sell the Product or shall substitute an equivalent Product acceptable to Navistar and extend the indemnity under the Supply Agreement to the substitute Product. The indemnity under the Supply Agreement does not extend to any claim or suit based on any infringement of any patent by the combination of Product(s) furnished by Core Materials with other components added thereto by Navistar, except when the Product(s) is a material part of the invention of an asserted patent and the components furnished by Navistar to complete the claimed combination, such as an engine, sensor, or vehicle frame, are not novel. The indemnity under the Supply Agreement does not extend to any infringement or alleged infringement arising solely out of Core Materials' compliance with Navistar-required specifications, designs, or instructions that (i) are created solely by Navistar and (ii) are thereafter furnished to Core Materials in writing.

Termination

The Supply Agreement is subject to termination for various reasons as set forth below:

(i) Termination for Default. At any time during the term of the Supply Agreement should either party default in performing any of its material obligations thereunder, the other party may give written notice of default giving the full details thereof. If the defaulting party fails within thirty (30) days of the receipt of written notice of default to cure the default, then the non-defaulting party shall have the right to terminate the Supply Agreement with regard to the particular Product materially affected by the default, or if the default materially affects all Products, the non-defaulting party shall have the right to terminate the Supply Agreement in its entirety. The non-defaulting party shall give the other party thirty (30) days written notice from the determination of the failure to cure the default, whereupon the termination shall be effective.

(ii) Termination for Insolvency: If either party is adjudicated as bankrupt or files a voluntary petition in bankruptcy, then, in accordance with applicable law, the other party shall have the right to terminate the Supply Agreement by giving such financially distressed party thirty (30) days written notice from the determination of the bankruptcy to cure the bankruptcy, whereupon the Supply Agreement shall automatically terminate.

(iii) Termination for Inadequate Quality: Navistar may terminate the Supply Agreement with regard to Products if adequate quality is not maintained in accordance with the terms of the Supply Agreement.

(iv) Termination for Failure to Remain Competitive: Navistar may terminate the Supply Agreement with regard to non-competitive Products as provided in the Supply Agreement as described above under "Failure to Stay Competitive".

(v) Force Majeure: If Force Majeure delays delivery of Products past 15 days, Navistar may terminate the Supply Agreement in whole or in part without penalty upon written notice to Core Materials.

83

THE TRANSITIONAL SERVICES AGREEMENT

As a condition to the consummation of the Acquisition, Navistar and Core Materials will enter into the Transitional Services Agreement. Under the terms of the Transitional Services Agreement, Navistar will (i) provide internal financial reporting, accounting, budgeting and tax planning and return preparation services and computer services to Core Materials for a period of one year after the Closing and Core Materials will pay for such services based on the actual hours incurred, determined based on (a) all compensation costs for direct personnel of Navistar who perform the services, (b) travel expenses (including meals and lodging expenses), and (c) ordinary and necessary business expenses incurred by Navistar and (ii) Navistar will provide office support services to Core Materials and procure insurance on Core Materials' behalf for various periods of time after the Closing depending upon the service (up to a period of three years) and Core Materials will pay for such services based on the actual hours incurred (determined as provided above) plus the cost to Navistar in providing such services. Total costs to be paid to Navistar under the Transitional Services Agreement are expected to approximate the amount of corporate general and administrative costs historically allocated to Columbus Plastics by Navistar. The Transitional Services Agreement will remain in effect until the earlier of (i) three years after the date thereof and (ii) the expiration of the longest time period specified under the Transitional Services Agreement, unless an event of termination occurs prior to the end of that period. If either party shall fail to perform or default in the performance of any of its obligations under the Transitional Services Agreement, the other party may give written notice that it intends to terminate the Transitional Services Agreement if such failure or default is not cured within forty-five days of such written notice. If any failure or default so specified is not cured within such forty-five day period, the non-defaulting party may elect to immediately terminate the Transitional Services Agreement; provided, however, that if the failure or default relates to a dispute made in good faith by the defaulting party, the non-defaulting party may not terminate the Agreement pending the resolution of such dispute. In addition, Navistar may immediately terminate the Agreement upon written notice to Core Materials if Core Materials fails to make any payment under the Transitional Services Agreement within fifteen days of the due date and either party may terminate the Agreement upon the occurrence of certain events involving the bankruptcy, insolvency or liquidation of the other party.

Under the terms of the Transitional Services Agreement, Navistar agrees to indemnify Core Materials against any and all claims, liabilities, damages, losses, costs, expenses, fines and penalties arising out of any actual injury, loss or damage of any nature whatsoever due or relating to the provision of or failure to provide the transitional services only if such amounts are a result of the negligence or reckless or willful misconduct of the personnel of Navistar or any contract personnel managed and directed by Navistar. Core Materials agrees to indemnify Navistar against any and all claims, liabilities, damages, losses, costs, expenses, fines or penalties arising out of any injury or death, and any loss or damage of any nature whatsoever (including, without limitation, loss or damage to property, or damage to the environment) arising out of the operations and activities of Core Materials, except for losses, liabilities, obligations, costs, expenses or damages which are the result of the negligence, gross negligence or willful misconduct of the personnel of Navistar or any personnel under contract with Navistar. The indemnification agreement in the Transitional Services Agreement will survive for a period of three years after the termination of the Transitional Services Agreement for any reason. Pursuant to the Agreement each party has agreed to hold any information received by it in strict confidentiality for a period of ten (10) years following the expiration or termination of the Asset Purchase Agreement.

THE REGISTRATION RIGHTS AGREEMENT

As a condition to the consummation of the Acquisition, Navistar and Core Materials will enter into the Registration Rights Agreement (the "Registration Rights Agreement"). Under the terms of the Registration Rights Agreement, Core Materials will grant Navistar certain demand and "piggy-back" rights with respect to the registration for sale under the Securities Act of the shares of Core Materials Common Stock received pursuant to the Asset Purchase Agreement. Navistar shall be entitled to demand two registrations on Form S-1 or any similar long-form registration and an unlimited number of registrations on Form S-2 or S-3 (including shelf registrations pursuant to Rule 415 under the Securities Act) or any similar short-form registrations. In addition, Navistar will be entitled to piggy-back registration rights, provided however, that if

84

the managing underwriter of an offering advises the Company that the inclusion of such shares of Core Materials Common Stock would have a material adverse effect on the offering, the Company may reduce the number of shares to be registered in accordance with the priorities set forth in the Registration Rights Agreement. The Company will be required to pay all expenses in connection with any registration, except underwriting discounts and commissions. Pursuant to the Registration Rights Agreement, the Company will agree to indemnify Navistar, its officers, directors, legal counsel, accountants and each person who controls Navistar against all losses, claims, damages, liabilities and expenses caused by (i) any untrue or alleged untrue statement of material fact contained in any registration statement, prospectus or preliminary prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading or (ii) any violation by the Company of the Securities Act or any regulation thereunder applicable to the Company and relating to action or inaction required of the Company in connection with any such registration, qualification or compliance.

PROPOSAL NO. 2--APPROVAL OF THE MERGER

INTRODUCTION

Navistar's obligation to consummate the Acquisition is conditioned, among other things, on the reincorporation of the Company in the State of Delaware. To effect the reincorporation and the desired amendments to the Company's charter and by-laws, the Company established Core Materials, a Delaware corporation, as a wholly-owned subsidiary. Core Materials' Certificate of Incorporation and By-laws contain provisions which would satisfy the requirements of Navistar in the Asset Purchase Agreement. If the Asset Purchase Agreement and the Merger Agreement are approved by the Company's stockholders and the other conditions to the Asset Purchase Agreement are satisfied or waived, the Company will be merged with and into Core Materials whereupon (i) the Company will cease to exist as a separate Maryland corporation, (ii) Core Materials will succeed, to the fullest extent permitted by law, to all of the business, assets and liabilities of the Company, (iii) the name of the surviving corporation will be "Core Materials Corporation", (iv) each share of Company Common Stock will be automatically converted into the right to receive one share of Core Materials Common Stock and
(v) the Certificate of Incorporation and By-laws of Core Materials will be the Certificate of Incorporation and By-laws of the surviving corporation of the Merger. The Merger will become effective upon the filing of certificate of merger with the Secretary of State of the State of Delaware and the Secretary of State of the filing of articles of merger with the State Department of Assessments and Taxation of Maryland (the "Effective Time"). It is presently anticipated that such filings will be made as soon as practicable after approval and adoption of the Asset Purchase Agreement and the Merger Agreement at the Special Meeting.

The Company's Board of Directors has approved, and recommends that the stockholders of the Company approve, the Merger Agreement by and between the Company and Core Materials, which provides for the merger of the Company with and into Core Materials.

The Company's Board of Directors believes that by reincorporating in Delaware the Company will be able to benefit from Delaware's comprehensive and well developed corporate laws. For many years Delaware has followed a policy of encouraging incorporation in that state. In furtherance of that policy, Delaware has adopted a modern and comprehensive corporation statute that has been periodically updated and revised to meet changing business needs. As a result, many publicly held corporations have initially chosen Delaware for their domicile or have subsequently reincorporated in Delaware in a manner similar to that proposed by the Company. Because of Delaware's historic significance as the state of incorporation for many publicly held corporations, the Delaware judiciary has become particularly familiar with matters of corporate law and corporate financial and business transactions, and a substantial body of court decisions has developed construing Delaware corporate law and establishing public policy with respect to Delaware corporations. As a consequence, a greater measure of predictability is possible in Delaware with respect to corporate legal affairs than is available in other states. While the Company will not be impeded in operating its business under Maryland law, the Company believes that Delaware law will offer clearer guidance with respect to issues that may arise, in particular with respect to a publicly-held corporation with a substantial stockholder having

85

effective control on future decisions involving ordinary business operations as well as extraordinary transactions.

STOCKHOLDERS OF THE COMPANY SHOULD NOT SURRENDER THEIR SHARE CERTIFICATES FOR EXCHANGE AFTER THE MERGER UNTIL THEY RECEIVE A TRANSMITTAL LETTER FOR THAT PURPOSE.

The approval of the Merger is contingent upon approval of the Asset Purchase Agreement (Proposal No. 1 herein) by the Company's stockholders. The vote required to approve this item is two-thirds of the outstanding shares of the Company Common Stock. If the Asset Purchase Agreement and the Merger are approved by the Company's stockholders at the Special Meeting, the Merger will be consummated as soon as practicable after all other conditions to the Asset Purchase Agreement are either satisfied or waived. If the Asset Purchase Agreement is not approved by the Company's stockholders at the Special Meeting, the Merger will not be consummated.

If the Merger is approved and completed, the Company and the rights of its stockholders, directors and officers will be governed by the Delaware General Corporation Law ("Delaware Law") and the Certificate of Incorporation, as amended, of Core Materials (the "Core Materials Charter") and Core Materials' By-laws (the "Core Materials By-laws"), rather than by the Maryland General Corporation Law ("Maryland Law") and the Amended and Restated Articles of Incorporation, as amended, of the Company (the "Company Charter") and the Amended and Restated By-laws, as amended, of the Company (the "Company By-laws"). Copies of the Company Charter and the Core Materials Charter are attached hereto as Annexes V and VI, respectively, and copies of the Company By-laws and the Core Materials By-laws are available for inspection at the principal executive offices of the Company and will be sent to Company stockholders upon request. The summary description of such documents contained herein is qualified in its entirety by reference to such documents.

DESCRIPTION OF CORE MATERIALS CAPITAL STOCK

The authorized capital stock of Core Materials will consist of 10,000,000 shares of preferred stock issuable in series and 20,000,000 shares of Common Stock, par value $.01 per share. The following statements are brief summaries of certain provisions with respect to Core Materials' capital stock contained in Core Materials' Charter or By-laws. The following summary is qualified in its entirety by reference thereto.

Core Materials Common Stock. Each outstanding share of Core Materials Common Stock is entitled to one vote on all matters submitted to a vote of stockholders, including the election of directors. The Core Materials Common Stock does not have cumulative voting rights. Dividends may be paid to the holders of Core Materials Common Stock when and if declared by the Board of Directors out of funds legally available for dividends. See "--Dividend Policy," below.

Holders of Core Materials Common Stock have no conversion, redemption or preemptive rights. Shares of Core Materials Common Stock to be issued in the Merger and the Stock Issuance will be fully paid and nonassessable. In the event of any liquidation, dissolution or winding-up of the affairs of Core Materials, the holders of Core Materials Common Stock will be entitled to share ratably in its assets remaining after provision for payment of creditors and after the liquidation preference of any preferred stock outstanding at the time.

Preferred Stock. The Board of Directors of Core Materials is empowered, without approval of the stockholders, to cause shares of preferred stock to be issued in one or more series, with the number of shares of each series and the powers, rights, preferences and limitations of each series to be determined by it. Among the specific matters that may be determined by the Board of Directors are: the annual rate of dividends; the redemption price, if any; the terms of a sinking or purchase fund, if any; the amount payable in the event of any voluntary liquidation, dissolution or winding up of the affairs of Core Materials; conversion rights, if any; and voting powers, if any. Satisfaction of any dividend preferences of outstanding preferred stock would reduce the amount of funds available for the payment of dividends on the Common Stock. Also, the holders of preferred stock would normally be entitled to receive a preference payment in the event of any liquidation, dissolution or winding-up of Core Materials before any payment is made to the holders of the Common Stock.

86

Upon any future issuance of a series of preferred stock, the holders of preferred stock will have no voting rights except as specifically required by statute and except for any voting rights specifically provided in the certificate of designation creating such series. In general, the vote of a majority of a class, voting as a class, is required to effect any change in the Core Materials Charter which would increase or decrease the par value of the shares of such class, or alter or change the powers, preferences or special rights of the shares of such class so as to affect them affect adversely (provided, that, if only certain series are affected, then only the shares of the series so affected shall be considered a separate class for purposes of voting on the proposed change).

Anti-takeover Measures. Core Materials Charter and By-laws contain provisions which may discourage certain types of transactions involving an actual or threatened change of control of Core Materials. These provisions are designed to make it more difficult to change majority control of the Board of Directors without its consent, and thus to reduce the vulnerability of Core Materials to an unsolicited proposal to restructure or sell all or part of Core Materials. These provisions may serve to encourage any person intending to attempt such a takeover to negotiate with the Board of Directors, and the Board of Directors will therefore be better able to protect the interests of the stockholders. These provisions include the following:

Removal of Directors. Core Materials Charter and By-laws provide that a director may be removed with or without cause upon the vote of the holders of at least 80% of the voting power of the outstanding shares of capital stock of Core Materials entitled to vote generally in the election of directors ("Voting Stock").

Supermajority Approval. Core Materials Charter requires that a merger and certain other transactions be approved by the affirmative vote of the holders of at least 66 2/3% of the then outstanding shares of Voting Stock. Such affirmative vote is required notwithstanding the fact that a lesser percentage may be specified by law.

Amendments. Core Materials Charter requires that any amendment to the provisions relating to the removal of directors be approved by the holders of at least 80% of the then outstanding shares of Voting Stock and any amendment to provisions requiring the approval of the holders of at least 66 2/3 of the then outstanding shares of Voting Stock be approved by the holders of at least 66 2/3% of the then outstanding shares of Voting Stock. These requirements will make it more difficult for stockholders who in the aggregate hold only a majority of the Common Stock from avoiding the requirements of the provisions discussed above by simply repealing such provisions.

Restrictions on Transfer. Core Materials Charter contains a provision (the "Prohibited Transfer Provision") designed to help assure the continued availability of the Company's substantial NOLs following the Merger by seeking to prevent an "ownership change" as defined under current Treasury Department income tax regulations. Protection against an "ownership change" is accomplished by prohibiting certain transfers of Core Materials Common Stock, preferred stock and any other instrument that would be treated as "stock" or an option under applicable federal income tax rules (collectively, "Stock"). Under the Prohibited Transfer Provision, if a stockholder transfers or agrees to transfer Stock, the transfer will be prohibited and void to the extent that it would cause the transferee to hold a "Prohibited Ownership Percentage" (as defined in Core Materials Charter) or if the transfer would result in the transferee's ownership increasing if the transferee had held a Prohibited Ownership Percentage within the three prior years or if the transferee's ownership percentage already exceeds the Prohibited Ownership Percentage under applicable federal income tax rules. A "Prohibited Ownership Percentage" is defined under Core Materials Charter by reference to complex federal tax laws and regulations, but generally means direct and indirect ownership of 4.5% or more (based on value) of Core Materials' Stock or any other percentage that would cause a transferee to be considered to be a 5-percent stockholder under applicable federal income tax rules. This transfer restriction is intended to prevent any person or group of persons from becoming a "5-percent stockholder" of Core Materials and to prevent an increase in the percentage stock ownership of any existing person or group of persons that constitutes a 5-percent stockholder. The use of a 4.5% limitation rather than a 5% limitation is intended to provide a margin of safety for market value fluctuations in avoiding an "ownership change." The Prohibited Transfer Provision will expire fifteen years after Core Materials Charter becomes effective, subject

87

to such expiration date being extended or accelerated in the event of a change in law upon a determination by Core Materials' Board of Directors that such action is reasonably necessary to preserve the tax benefits, in the case of an extension, or that the restrictions are no longer reasonably necessary for the preservation of the tax benefits, in the case of an acceleration. The Prohibited Transfer Provision does not prevent transfers of Stock between persons who do not hold a Prohibited Ownership Percentage.

The acquisition of Stock from an individual or entity that owns directly 5% of the stock of Core Materials would be deemed to result in the identification of a separate, segregated "public group" which is a new 5-percent stockholder. Consequently, the Prohibited Transfer Provision will prohibit certain transfers of equity interests by, and other actions involving, persons having a Prohibited Ownership Percentage, unless the transfer or other action is approved by Core Materials' Board of Directors in advance or permitted by a Core Materials Board resolution.

The Prohibited Transfer Provision does not apply to the issuance of Core Materials Common Stock to Navistar pursuant to the Asset Purchase Agreement, to any transfer that has been approved in advance by Core Materials' Board of Directors, which is made in compliance with certain exceptions set forth in the Prohibited Transfer Provision or exceptions established from time to time by resolution of Core Materials' Board of Directors. The Board may permit an otherwise prohibited transfer if it reasonably and in good faith determines that a waiver would be in the best interest of the Company.

In addition to voiding prohibited transfers, the Prohibited Transfer Provision provides a method of nullifying the effect of certain prohibited transfers after the transfers have purportedly occurred. If such a purported transfer is made in violation of the Prohibited Transfer Provision, the transferee (the "Purported Transferee") will not be recognized as the owner of the Stock. If Core Materials' Board of Directors determines that such a purported transfer has violated the Prohibited Transfer Provision, the Company shall require the Purported Transferee to surrender the relevant Stock and any dividends he or she has received on them to an agent designated by the Board (the "Agent"). The Agent will sell the Stock in an arm's length transaction (on the American Stock Exchange, if possible). If the Purported Transferee has resold the Stock before receiving the Company's demand to surrender them, the Purported Transferee generally will be required to transfer to the Agent the proceeds of the sale and any distributions he or she has received on the Stock. After repaying its own expenses and reimbursing the Purported Transferee for the price paid for the Stock (or the fair market value of the Stock at the time of the attempted transfer to the Purported Transferee by gift, inheritance or similar transfer), the Agent will pay any remaining amounts to charities designated by the Company.

Delaware Anti-takeover Provisions. Core Materials is governed by the provisions of Section 203 of the Delaware Law ("Section 203"), which prohibits a publicly held Delaware corporation from engaging in a "business combination" with an "interested stockholder" for a period of three years following the time that such stockholder became an interested stockholder, unless (i) prior to such time either the business combination or the transaction which resulted in the stockholder becoming an interested stockholder is approved by the board of directors of the corporation, (ii) upon consummation of the transaction which resulted in the stockholder becoming an interested stockholder, the interested stockholder owns at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced (other than certain excluded shares) or
(iii) on or after such time the business combination is approved by the board and authorized at an annual or special meeting of stockholders, and not by written consent, by the affirmative vote of at least 66 2/3% of the outstanding voting stock which is not owned by the interested stockholder. A "business combination" includes certain mergers, consolidations, asset sales, transfers and other transactions resulting in an increase in the percentage of any class or series of stock owned by the interested stockholder or in a financial benefit to the stockholder. An "interested stockholder" is a person who, together with affiliates and associates, owns (or, in certain cases, within three years, did own) 15% or more of the corporation's voting stock.

Dividend Policy. Core Materials currently intends to retain earnings to finance the growth and development of its business and does not anticipate paying cash dividends in the foreseeable future. Moreover, Core Materials will be prohibited from paying dividends on its Common Stock by covenants contained in the

88

Secured Note. See "PROPOSAL NO. 1--APPROVAL OF THE ACQUISITION--Ancillary Agreements--The Secured Note--Covenants--Negative Covenants."

Reverse Stock Split. In connection with obtaining the approval of Core Materials' listing application for listing the Core Materials Common Stock on the American Stock Exchange, Core Materials has agreed with the American Stock Exchange that, in the event that the average closing price of Core Materials Common Stock is not at least $3.00 per share for a 20 day trading period during the six month period commencing on the date of the approval of Core Materials' listing application, and during such 20 day period the closing price for any five consecutive trading days in such period is less than $3.00 per share, Core Materials shall, subject to the approval of Core Materials' stockholders as required under Delaware law, effect a reverse stock split of the Core Materials Common Stock with the anticipated result of increasing the trading price per share to at least $3.00 per share. If a reverse stock split is required pursuant to the preceding sentence, Core Materials has agreed to call a meeting of stockholders and to solicit proxies in order to obtain the required approval of Core Materials stockholders.

CERTAIN EFFECTS OF THE MERGER

The following table summarizes certain material differences between the provisions of Maryland Law and the Company's Charter and By-laws, on the one hand, and the provisions of Delaware Law and the Core Materials Charter and By-laws, on the other hand. Although the Merger will result in substantive changes in the Company's Charter and By-laws which could affect the stockholders and the Company's officers and directors, the Company's management does not believe that such changes will result in any material benefits to directors and officers or any material detriments to stockholders. Core Materials' Charter and By-laws are substantially different from the Company's Charter and By-laws. The following table is not intended to be a complete description of all of the effects of the Merger, and stockholders are advised to review the Company's Charter and By-laws and the Core Materials Charter and By-laws.

the acquiror, by officers or by directors who
are employees of the corporation. "Control
shares" are voting shares of stock which, if
aggregated with all other such shares of stock
previously acquired by the acquiror or in
respect of which the acquiror is able to
exercise or direct the exercise of voting
power (except solely by virtue of a revocable
proxy), would entitle the acquiror to exercise
voting power in electing directors within one
of the following ranges of voting power: (i)
one-fifth or more but less than one-third,
(ii) one-third or more but less than a
majority, or (iii) a majority or more of all
voting power. Control shares do not include
shares the acquiring person is then entitled
to vote as a result of having previously
obtained stockholder approval. A "control
share acquisition" means the acquisition of
control shares, subject to certain exceptions.

A person who has made or proposes to make a
control share acquisition, upon satisfaction
of certain conditions (including an
undertaking to pay expenses), may compel the
board of directors of the corporation to call
a special meeting of stockholders to be held
within 50 days of demand to consider the
voting rights of the shares. If no request for
a meeting is made, the corporation may itself
present the question at any stockholders
meeting.

If voting rights are not approved at the
meeting or if the acquiring person does not
deliver an acquiring person statement as
required by the statute, then, subject to
certain conditions and limitations, the
corporation may redeem any or all of the
control shares (except those for which voting
rights have previously been approved) for fair
value determined, without regard to the
absence of voting rights for the control
shares, as of the date of the last control
share acquisition by the acquiror or of any
meeting of stockholders at which the voting
rights of such shares are considered and not
approved. If voting rights for control shares
are approved at a stockholders meeting and the
acquiror becomes entitled to vote a majority
of the shares entitled to vote, all other
stockholders may exercise appraisal rights.

SIGNIFICANCE OF DIFFERENCES BETWEEN THE COMPANY AND CORE MATERIALS

The following is a discussion of the significance of some of the differences between the Company and Core Materials described in the foregoing table, in particular those relating to potential acquisitions of the corporation and the limitation of liability and indemnification of RYMAC officers and directors. Management does not believe any of such effects will result in any material benefit to the Company's officers or directors or any material detriment to stockholders.

Restrictions on Certain Business Combinations. The Core Materials Charter contains a provision that requires the approval of at least 66 2/3% of the outstanding shares of Core Materials' Common Stock for certain mergers, the sale, lease or exchange of substantially all of Core Materials' assets and approval of a plan of liquidation or dissolution. In addition, as discussed above both Maryland Law and Delaware Law impose an additional set of statutory restrictions which restrict business combinations with significant stockholders. The purpose of both the Charter and the statutory restrictions is to encourage any potential bidder for control of the corporation to attempt to negotiate an acquisition directly with the board of directors and to discourage tender offers made directly to the stockholders.

The Delaware statutory restrictions, which are applicable to Core Materials, and the Maryland statutory restrictions, which are applicable to the Company, differ in a number of ways. First, the statutory moratorium imposed by Delaware Law for transactions with interested stockholders extends for three years as opposed to the five year moratorium imposed by Maryland Law. Delaware Law imposes no further restrictions once the three-year period expires, while the prohibition imposed by Maryland Law on a proposed combination continues indefinitely unless and until the transaction is approved by eighty percent of the voting stock and a majority of the disinterested directors or the transaction satisfies the fair-pricing requirement. The Delaware statutory moratorium does not apply if the percentage of voting stock held by the interested stockholder is less than fifteen percent, whereas the Maryland statutory restriction applies so long as the percentage is at least 10%.

An additional distinction between Delaware Law and Maryland Law exists as to the size of the super-majority stockholder vote required to avoid the moratorium or prohibition. The vote required by the Delaware statute is two-thirds of the shares of the disinterested stockholders, whereas the vote required under Maryland Law is eighty percent of all the voting stock, including shares held by the interested stockholder. Assuming that an interested stockholder held fifteen percent of the outstanding voting stock (the minimum required to trigger both sets of statutory requirements), the minimum vote required to approve the transaction would be seventy-six percent of the disinterested stockholders of the Company, which would be subject to the Maryland statute, compared to two-thirds of the disinterested stockholders of Core Materials, which would be subject to

98

the Delaware statute. Thus, it would be easier for an interested stockholder to satisfy the statutory minimum stockholder vote requirement after the Merger.

In addition to the statutory and charter provisions described above, Navistar's ownership interest in Core Materials may have certain anti-takeover effects. Navistar will own approximately 45% of the voting stock of Core Materials on a fully diluted basis immediately following the Acquisition, which will enable Navistar to preclude mergers and the sale, lease or exchange of substantially all of Core Materials' assets pursuant to the Core Materials Charter provisions described above. So long as Navistar owns a control block of Core Materials stock it is unlikely that any potential acquirer will attempt a hostile bid for control of Core Materials. There can be, however, no assurance that Navistar will not sell some or all of its interest in Core Materials and Navistar has entered into the Registration Rights Agreement with the Company pursuant to which the Company has agreed to file registration statements under the 1933 Act for that purpose.

Removal of Directors and Officers. The Company By-laws provide that the Company's stockholders may, by the vote of a majority of the Stockholders entitled to vote, remove any director or officer with or without cause. As permitted by Delaware Law, The Core Materials Charter (and By-laws) provide that a director may be removed from office with or without cause only upon the vote of the holders of at least 80% of the voting power of the outstanding shares of capital stock of Core Materials entitled to vote generally in the election of directors.

The Core Materials Charter and By-laws do not provide stockholders with the right to remove officers.

The provisions in the Core Materials Charter and By-laws that restrict the removal of directors tend to maintain the incumbency of the existing directors and make it more difficult for stockholders who do not agree with the policies of the Board of Directors to replace a majority of the Board of Directors in an relatively short period of time.

Limitations on Director Liability. The Company and Core Materials Charters both extend the protection available to directors from monetary liability to the corporation and its stockholders to the full extent permissible under the respective state laws. Because Maryland Law is more advantageous to directors in this regard, the directors will be afforded less protection from personal liability, and the circumstances under which stockholders may be able to establish claims for monetary damages against directors will be increased, as a result of the Merger. However, in neither case is a director protected against claims by third parties, claims for equitable relief such as rescission or injunctive relief, or claims arising out of their responsibilities under the federal securities laws. Moreover, although Maryland Law permits broader limitations of liability than Delaware Law, the degree of difference is small. In both cases, the inclusion of such provisions in the charter documents enhances the corporation's ability to attract qualified directors.

Limitations on Officer Liability. The Company Charter also differs from the Core Materials Charter in that, as permitted by Maryland Law, it protects officers of the Company against liability to the corporation or its stockholders for monetary damages arising from any claim for breach of fiduciary duty to the same extent that it protects directors. Although the Core Materials Charter cannot, under Delaware Law, limit the liability of officers, the Core Materials Charter does provide for the indemnification of officers to an extent generally consistent with the Maryland limitations of liability.

Indemnification. Both the Company and Core Materials charter documents provide for the indemnification of officers and directors to the full extent permitted by applicable state law. The two states' indemnification laws are similar in most respects. However, Maryland Law appears to be more favorable to an officer or director as to civil liabilities insofar as it requires, in order to deny indemnification to any person, a finding that the person's conduct was material to the underlying injury and was either committed in bad faith or the result of active and deliberate dishonesty or that the person actually received an improper personal benefit. In contrast, Delaware Law requires that indemnification be denied unless the person shows that he acted in good faith and in a manner in or not opposed to the best interest of the corporation, thus shifting the burden of proof and imposing a higher standard. However, as in the case of the limitation of officer and director liability, management believes that in practice this distinction is unlikely to have a material effect on the ability of an officer or director to obtain indemnification.

99

Restriction on Transfer of Shares to Preserve NOLs. The Core Materials Charter differs from the Company Charter in that the Core Materials Charter includes the Prohibited Transfer Provision in order to help ensure the continued availability of the Company's substantial NOLs following the Merger. As discussed above, see "Description of Core Materials Capital Stock--Restrictions on Transfer", the Prohibited Transfer Provision accomplishes this by seeking to prevent an "ownership change", as defined under current Treasury Department income tax regulations, by prohibiting certain transfers of Core Materials Common Stock, preferred stock and any other instrument that would be treated as "stock" or an option under applicable federal income tax regulations that would cause a person to hold a Prohibited Ownership Percentage or would increase the ownership percentage of any person who has held a Prohibited Ownership Percentage within three years prior to the proposed transfer. Although the Prohibited Transfer Provision may have the effect of impeding a stockholder's attempt to acquire a significant or controlling interest in Core Materials, the purpose of the Prohibited Transfer Provision is to preserve tax benefits, not to insulate management from change. The Company believes the tax benefits outweigh any anti-takeover effect of the Prohibited Transfer Provision. See "CERTAIN CONSIDERATIONS." Any antitakeover effect of the Prohibited Transfer Provision will end when the Prohibited Transfer Provision terminates.

Redemption and Prohibition on Transfer of Shares Preserving REIT Status. To protect the Company's qualification as a REIT under the Code, the Company Charter provides that if the Board of Directors determines that share ownership of the corporation has or may become concentrated to an extent that would prevent the corporation from qualifying as a REIT, the Board is authorized to prevent the transfer of, or redeem (by lot or otherwise), a number of shares sufficient to maintain the corporation's qualification as a REIT for tax purposes. The Core Materials Charter does not contain a similar provision because if the Acquisition is consummated the Company will cease to be a REIT effective for its tax year ending December 31, 1996.

Authorized Capital. The Company has 50,000,000 shares of authorized common stock, par value $0.01 per share; Core Materials has 20,000,000 shares of authorized Common Stock, par value $0.01 per share. Core Materials also has 10,000,000 shares of authorized preferred stock. The Core Materials Charter provides that the shares of preferred stock may be issued from time to time, in one or more classes or series, each of which class or series shall have such rights as may be fixed by the Board of Directors. Each class can have voting rights, full or limited, or no voting powers, and such preferences or other special rights or such qualification, limitations or restrictions thereof, as stated in the resolution authorizing the issuance of such securities. Satisfaction of any dividend preferences of outstanding preferred stock would reduce the amount of funds available for the payment of dividends on the Core Materials Common Stock. The holders of preferred stock would also normally be entitled to receive a preference payment in the event of any liquidation, dissolution or winding-up of Core Materials before any payment is made to the holders of Core Materials Common Stock. In addition, a "blank check" preferred stock provision like Core Materials' may be used by the Board of Directors as an anti-takeover device as it allows the Board to issue preferred stock with provisions that may help to deter hostile suitors. The Company Charter does not have any authorized capital stock specifically designated preferred stock but the Charter does permit the Board of Directors to authorize and issue from time to time additional classes of stock from the Company's unissued shares of capital stock without the necessity of further approval by the stockholders and with such rights and preferences as the Board of Directors of the Company may designate by resolution. This is in effect a "blank check" preferred stock provision similar to the one contained in the Core Materials Charter.

SIGNIFICANT CHARTER AND BY-LAW PROVISIONS NOT
MATERIALLY AFFECTED BY THE MERGER

Following is a discussion of certain Charter and By-law provisions in which management believes RYMAC stockholders may be interested even though such provisions will not be materially affected by the Merger.

Stockholder's Inspection Rights. Although, as described above, there are differences between Delaware Law and Maryland Law which affect stockholders' general access to the Company's stockholder list, both the Company By-laws and the Core Materials By-laws permit any stockholder to inspect such list at least ten days

100

prior to any stockholder meeting for any purpose germane to such meeting. Moreover, for so long as RYMAC remains a public company and subject to the Exchange Act, those state law differences will not affect the rights of stockholders under federal law to require the Company and Core Materials either to provide a list of security holders or to mail a stockholder's proxy materials whenever the Company or Core Materials may solicit proxies for a stockholder vote.

Preemptive Rights. Both the Company's Charter and the Core Materials Charter disallow any stockholder any preemptive right to subscribe for any newly issued stock or other securities of the corporation.

NO DISSENTERS' RIGHTS OF APPRAISAL

Section 3-202 of the Annotated Code of Maryland provides that stockholders of a Maryland corporation do not have appraisal rights when a Maryland corporation whose shares are listed on a national securities exchange merges with and into another corporation. Consequently, since the Company Common Stock is listed on the American Stock Exchange, dissenters' rights are not available with respect to the Merger.

THE BOARD OF DIRECTORS OF THE COMPANY BELIEVES THAT THE MERGER IS IN THE BEST INTERESTS OF THE COMPANY AND RECOMMENDS THAT THE STOCKHOLDERS VOTE IN FAVOR OF THE MERGER.

FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER AND THE ACQUISITION

The Merger. The Merger has been structured to qualify as a "reorganization" under Section 368 of the Code. If the Merger qualifies as a reorganization, no gain or loss will be recognized by the holders of Company Common Stock as a result of receiving Core Materials Common Stock. Each stockholder will have the same basis in the shares of Core Materials Common Stock as in the shares of Company Common Stock held immediately prior to the time the Merger becomes effective and the holding period of the shares of Core Materials Common Stock will include the period during which the corresponding shares of Company Common Stock were held. In addition, no gain or loss will be recognized by the Company upon its transfer of assets to Core Materials and Core Materials will have the same basis as the Company in the assets transferred and will succeed to certain tax attributes of the Company including the Company's NOLs, earnings and profits, and capital loss carryovers.

There are certain technical legal requirements for the Merger to qualify as a reorganization. In addition, there are certain factual requirements in that there must be a business purpose for the Merger, Core Materials must continue to use the historic business assets of the Company or continue the Company's historic business, and there must be a continuity of stockholders from the Company to Core Materials. Although the matter is not free from doubt, the Merger should satisfy the legal and factual requirements to be treated as a reorganization and the discussion below assumes that the Merger will so qualify. However, the Company has not requested a ruling from the IRS with respect to the Merger and it is possible that the IRS will disagree. If the IRS were to successfully challenge the Merger as not qualifying as a reorganization, stockholders would recognize gain or loss on the exchange of their shares of stock in the Company and Core Materials would not be allowed to succeed to any tax attributes of the Company including its NOLs, earnings and profits, and capital loss carryovers.

Utilization of Net Operating Losses and Capital Loss Carryforwards. Generally, a taxpayer is allowed to carry its net operating losses forward up to 15 years following the taxable year in which such losses arose. Substantially all of the Company's net operating losses arose during or subsequent to its 1992 taxable year. As a consequence of the Merger, Core Materials will succeed to the Company's remaining carryover period on its NOLs.

A taxpayer is able to utilize a net operating loss that arose in a year in which it qualified as a REIT in a subsequent year in which it no longer qualified as a REIT. Accordingly, Core Materials will not be prevented from using the net operating losses of the Company solely because its operations and assets will no longer allow for qualification as a REIT.

101

The Company is entitled to carry a net long term capital loss forward up to 5 years following the taxable year in which such losses arose. Also as a consequence of the Merger, Core Materials will succeed to the Company's remaining carryover period on its capital losses. Capital losses can only be offset by capital gains and not by ordinary income. Although most of the Company's capital losses arose during or subsequent to its 1994 taxable year, Core Materials is not expected to recognize any significant capital gains that would allow it to utilize the capital loss of the Company before such capital losses carryforwards expire.

The ability of Core Materials to utilize the NOLs of the Company will be severely restricted under Code Section 382 if Core Materials under goes a "change of control." Code Section 382 limits a corporation's utilization of its net operating losses when certain changes in the ownership of the corporation's stock occur within a three year period. If the Code Section 382 limitation is triggered as a result of future shifts in ownership of Core Materials, combined with shifts in ownership that have already occurred and those that will occur as a result of the issuance and sale of the shares of Common Stock to Navistar, Core Materials would be permitted to deduct only a limited amount of its net operating losses in each taxable year that ends after the triggering event occurs. This limitation could cause Core Materials' tax expense to be greater than if no limitation existed and could cause the majority of Core Materials' NOLs to expire before it would be permitted under the limitation imposed by Code
Section 382 to utilize such NOLs.

The Code Section 382 limitation is generally triggered when more than 50 percent of the value of a corporation's stock is acquired by one or more stockholders during any three year period (a "Change in Control") generally treating all shares of the same class as having the same value. The rules for determining whether a Change in Control has occurred are complex and dependent upon a number of factual matters, including actions taken by stockholders of the Company with respect to Common Stock held by them. Certain acquisitions of stock, such as purchases of stock by stockholders owning less than 5 percent of the value of a corporations total stock, are disregarded for purposes of determining whether a Change in Control has occurred. The Charter of Core Materials contains certain transfer restrictions designed to prevent a Change in Control from occurring subsequent to the Merger. In addition, the Asset Purchase Agreement provides for a retroactive reduction of shares to be issued to Navistar to prevent a Change in Control in the event that Core Materials learns of share acquisitions after the Asset Purchase that occurred prior to the Merger which create a risk that Core Materials would otherwise be treated as having a Change in Control. The Company has not requested any ruling from the IRS that these restrictions will prevent a Change of Control and there can be no assurance that a Change of Control will not occur at a point in time when Core Materials would still have substantial unutilized NOLs.

The consideration paid to Navistar has been structured to prevent a Change in Control. However, for corporations with significant net operating losses the treasury regulations interpreting Code Section 382 require treating as stock interests that are not otherwise stock for purposes of determining whether there has been a Change in Control if treating such interest as stock would result in a Change in Control and such interest at the time it is created offers a potential significant participation in the growth of the corporation. The scope of these provisions is uncertain, and accordingly, it is unclear whether the provisions of the Asset Purchase Agreement (other than the right to receive Common Stock) create rights that could be construed as a representing interests that must be treated as stock or a different class of stock. The Company does not believe that any provision of the Asset Purchase Agreement other than the rights to receive Common Stock should be treated as creating a right to an interest that is treated as stock for purposes of Code Section 382. The Company has not requested a ruling from the IRS with respect to this issue, and accordingly, there can be no assurance that the IRS will not assert a contrary position or whether such a contrary position, if asserted, would not prevail.

For alternative minimum tax purposes, net operating losses can be used to offset no more than 90 percent of alternative minimum taxable income ("AMTI"). Thus to the extent that the net operating losses of the Company are used to offset regular taxable income, alternative minimum tax will still be required to be paid on 10 percent of AMTI at the alternative minimum tax rate of 20 percent. In addition, if the Code Section 382 limitation were triggered, the amount of NOLs that could be used to offset AMTI would be subject to limitations similar to those described above for utilization of NOLs to offset income subject to the regular income tax.

102

In addition, to Section 382, there are other statutory and common law restrictions on the ability of taxpayers to utilize NOLs. In particular, under section 269 if control of a corporation (generally 50% of the vote or value of a corporation's stock) is acquired for the principal purpose of utilizing the tax attributes the IRS can disallow the use of such tax attributes. Although technically stockholders of the Company are acquiring control of Core Materials, such acquisition should not be treated as having the principal purpose of utilizing tax attributes. In addition, if the Secured Note were to be treated as equity for federal income tax purposes, Navistar could be treated as having acquired control of Core Materials for purposes of Section 269 even if it would not be treated as having acquired control of Core Materials for purposes of
Section 382 (which excludes certain types of preferred stock for purposes of determining whether a Change in Control has occurred). As a consequence, Core Materials would not be entitled to an interest deduction for interest paid to Navistar and Core Materials' ability to use the NOLs and capital loss carryforwards of the Company could be disallowed. However, based on the intent of the parties and the terms of the debt, and that the Secured Note is held only by Navistar and not by all stockholders, it should be respected as debt and not treated as equity for federal income tax purposes.

Statutory or common law restrictions on the utilization of NOLs other than those discussed above should not limit Core Materials' ability to utilize the NOLs of the Company.

Consequences of Receiving Dividends from a Company Not Taxable as a REIT.

As a consequence of the Asset Purchase neither the Company nor Core Materials will qualify as a REIT during 1996 or thereafter. As a consequence, the Company and Core Materials will be subject to federal income taxes on taxable income earned during 1996 and thereafter and will not be entitled to a deduction for any dividends paid to stockholders. In addition, Core Materials will not be subject to the required distribution rules applicable to REITs. Corporate stockholders that satisfy certain holding period requirements will be entitled to a dividends received deduction on dividends paid out of Core Materials' accumulated or current earnings and profits. Core Materials, however, generally does not intend to pay dividends. See "Description of Core Materials Capital Stock--Dividend Policy"

Stockholders should consult their own tax advisors as to the effect of the Merger under applicable state or local tax laws.

ACCOUNTING TREATMENT

Based upon the terms of the proposed Acquisition, for financial reporting and accounting purposes the transaction will be accounted for as a reverse acquisition whereby Columbus Plastics will be deemed to have acquired Core Materials. However, Core Materials, subsequent to the merger, will be the continuing legal entity and registrant for both Commission filing purposes and income tax reporting purposes. Consistent with reverse acquisition accounting treatment, Core Materials will carry forward the historical basis of the acquired assets and assumed liabilities of Columbus Plastics and will revalue the basis of its net assets to fair value. Should there be an additional contingent earn-out adjustment, it will be accounted for by increasing the amount of the Secured Note, and by reducing the amount of Core Materials' retained earnings. See "Unaudited Pro Forma Combined Financial Information of Core Materials."

LEGAL MATTERS

The validity of the Core Materials Common Stock to be issued in the Merger and in the Stock Issuance will be passed upon by Brown & Wood LLP.

INDEPENDENT AUDITORS' REPORT

Columbus Plastics Operation
Columbus, Ohio

We have audited the accompanying statements of assets and liabilities and equity investment of the Columbus Plastics Operation (an operating unit of Navistar International Transportation Corp., ("NITC")) as of October 31, 1995 and 1994 and the related statements of revenues, direct expenses and identified corporate expenses before interest and taxes for each of the three years in the period ended October 31, 1995. These financial statements are the responsibility of Columbus Plastics' management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing standards. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

As explained in Note 2, Columbus Plastics Operation is an operating unit of NITC and the results of its operations are not necessarily indicative of those which may have resulted had it been a stand alone Company.

In our opinion, such financial statements present fairly, in all material respects, the assets and liabilities and equity investment of the Columbus Plastics Operation (an operating unit of Navistar International Transportation Corp.) as of October 31, 1995 and 1994 and the results of its direct operations and identified corporate expenses before interest and taxes for each of the three years in the period ended October 31, 1995 in conformity with generally accepted accounting principles.

COLUMBUS PLASTICS OPERATION
(AN OPERATING UNIT OF NAVISTAR INTERNATIONAL TRANSPORTATION CORP.)

NOTES TO FINANCIAL STATEMENTS

1.    NATURE OF OPERATIONS

      Columbus Plastics Operation ("Columbus Plastics"), an operating unit of Navistar
      International Transportation Corp. ("NITC"), is a manufacturing plant that produces
      Sheet Molding Composite ("SMC") plastic components. Columbus Plastics has two
      principal customers, NITC and Yamaha, and provides NITC's truck assembly operations
      with all of its SMC requirements, primarily hoods and air deflector shields.

2.    BASIS OF PRESENTATION

      Columbus Plastics is not a "stand alone" division or subsidiary of NITC and was
      generally not accounted for separately. As a result, the distinct and separate
      accounts necessary to present individual Columbus Plastics' balance sheets and income
      statements as of October 31, 1995 and 1994 and for the three years in the period
      ended October 31, 1995 are not maintained.

      Columbus Plastics does not maintain corporate treasury, legal, tax, purchasing and
      other similar corporate support functions. Corporate general and administrative
      expenses have not been previously allocated to Columbus Plastics. For purposes of
      preparing the financial statements certain of these corporate costs along with other
      NITC Truck Group expenses were allocated using an allocation method (see Note 8).
      However, NITC's systems and procedures do not provide sufficient information to
      develop a reasonable cost allocation for income taxes, corporate debt and interest
      expense.

      With respect to cash flows; purchases of inventory, payroll, capital and other
      expenditures are funded through Columbus Plastics' intercompany Equity Investment
      account with NITC. Accounts payable to Columbus Plastics' third party vendors and
      certain expense accruals are processed and recorded at other NITC locations.
      Remittances from sales to third parties are collected by NITC and are accounted for
      through the intercompany Equity Investment account as are sales to NITC's truck
      assembly operations. Accordingly, Columbus Plastics has no operating cash flows.

      FINANCIAL STATEMENT PRESENTATION--Based upon the above information, the following
      financial information is presented:

      - Statements of Assets and Liabilities and Equity Investment. Assets and Liabilities

      - Statements of Revenues, Direct Expenses and Identified Corporate Expenses before
        Interest and Taxes, including all corporate cost allocations for which a reasonable
        method of allocating the costs to the operations could be developed.

      - Statements of Cash Flows are not presented, because as explained above Columbus
        Plastics has no cash flows. Note 5 to the financial statements presents a
        reconciliation of the Equity Investment account for all periods presented.

3.    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

      INTERIM FINANCIAL INFORMATION--In the opinion of management, the unaudited
      information presented as of and for the period ended July 31, 1996 reflects all
      adjustments, which consist of normal recurring adjustments, necessary for a fair
      presentation of the interim periods. Operating results for interim periods are not
      necessarily indicative of the results that may be expected for a full year.

      USE OF ESTIMATES--The preparation of financial statements in conformity with
      generally accepted accounting principles requires management to make estimates and
      assumptions that affect the reported amounts of assets and liabilities, disclosure of
      contingent assets and liabilities and reported

F-4

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

amounts of revenues and expenses during the reporting period. Actual results could
differ from those estimates.

REVENUE RECOGNITION--Columbus Plastics records sales to other NITC manufacturing
plants at its standard cost, at date of shipment. Sales to third party customers are
recorded at negotiated prices at date of shipment.

INVENTORIES--Inventories are stated at the lower of cost (standard cost) or market.

PROPERTY, PLANT AND EQUIPMENT--Property, plant and equipment are recorded at cost.
Depreciation is provided on a straight line method over the estimated useful lives of
the assets. The carrying amount of long-lived assets is evaluated annually to
determine if adjustment to the depreciation period or to the unamortized balance is
warranted.

Ranges of estimated useful lives for computing depreciation are as follows:
 Land improvements...............................................        20 years
 Building and improvements.......................................     20-50 years
 Machinery and equipment.........................................      3-25 years
 Tools, dies and patterns........................................       3-5 years

FAIR VALUE OF FINANCIAL STATEMENTS--Columbus Plastics' financial instruments consist
of accounts receivable and payable. The carrying amounts of the financial instruments
approximate their fair value.

      Construction in progress primarily relates to the purchase and installation of SMC
      presses and certain other SMC capital projects. Substantially all amounts included in
      construction in progress at October 31, 1995 and July 31, 1996 are expected to be
      placed in service within twelve months from each respective period end. At October
      31, 1995 and July 31, 1996 commitments for capital expenditures in progress, relating
      to SMC presses, were approximately $1,800,000 and $9,000, respectively. Columbus
      Plastics does not record capitalized interest on construction in progress as interest
      expense is not allocated by NITC to Columbus Plastics.

      FUNDING OF PURCHASES--represents amounts funded by NITC primarily for purchases of
      materials for Columbus Plastics and capital expenditures.

      NET CHARGES TO NITC--represents costs incurred by NITC on behalf of Columbus Plastics
      for payroll and related expenses, for employee health and welfare plans, payments to
      union sponsored pension plans and all corporate support services.

      NITC FUNDING OF PLANT EXPENSES--represents amounts transferred to Columbus Plastics
      from NITC for payment of expenses by Columbus Plastics.

      NET CHARGES TO NITC--represents the intercompany sales and billings by Columbus
      Plastics to other NITC manufacturing plants for the sale of SMC products.

      COLLECTIONS FROM THIRD PARTIES--represents remittances from sales to third parties
      which are collected by NITC. Amounts primarily relate to sales to Yamaha, and
      billings for tooling projects.

6.    LEASE COMMITMENTS

      Columbus Plastics has long-term noncancellable leases for use of equipment under
      operating lease agreements. Total rent expense under such agreements amounted to
      approximately $560,000 in 1995, $540,000 in 1994, and $484,000 in 1993.

      At October 31, 1995, the aggregate minimum future rental commitments under such
      noncancellable leases with terms in excess of one year were approximately $550,000 in
      1996; $569,000 in 1997; $569,000 in 1998; $273,000 in 1999; $179,000 in 2000; and
      $45,000 thereafter.

7.    POSTRETIREMENT BENEFITS

      Columbus Plastics employees are participants in the NITC sponsored pension and
      postretirement plans. NITC allocates postretirement benefit costs to Columbus
      Plastics based upon the number of Columbus Plastics participants and their respective
      demographic data. Total expense includes the pension expense for salaried employees,
      retirees and surviving spouses, and postretirement health care

F-6

COLUMBUS PLASTICS OPERATION
(AN OPERATING UNIT OF NAVISTAR INTERNATIONAL TRANSPORTATION CORP.)

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

and life insurance expense for all employees, retirees and surviving spouses and
dependents. The NITC pension plan is non-contributory with benefits related to an
employee's length of service and compensation rate. The NITC postretirement plan
provides health care and life insurance for retired employees; spouses and certain
dependents and calls for cost sharing between NITC and the participants in the form
of premiums, co-payments and deductibles. In addition, all of Columbus Plastics union
employees are covered under a multi-employer defined benefit plan administered under
a collective bargaining agreement. This plan is not administered by Columbus Plastics
and contributions are determined in accordance with provisions in the negotiated
labor contract.

Pursuant to the terms of the Asset Purchase Agreement (see Note 10) NITC will
withdraw from the multi-employer plan, and, simultaneously, RYMAC will take over
NITC's former responsibilities in regards to the multi-employer plan. NITC management
has been advised by the multi-employer plan's actuary that its withdrawal from the
plan will not result in a withdrawal liability.

The costs of postretirement benefits including the effect of the corporate allocation
adjustments (see Note 8) are segregated as a separate component in the Statements of
Revenues, Direct Expenses and Identified Corporate Expenses Before Interest and Taxes
and approximate the following:

8.    CORPORATE ALLOCATIONS

      Columbus Plastics does not maintain corporate treasury, computer, legal, tax,
      purchasing and other similar corporate support functions. Columbus Plastics does
      record certain budgeted corporate expenses related primarily to employee benefits,
      real estate taxes and insurance. Adjustments to these amounts to reflect actual
      expenditures are not recorded by Columbus Plastics but are included in the corporate
      allocation amounts noted below. For purposes of preparing the financial information
      for Columbus Plastics certain corporate costs and credits along with other NITC Truck
      Group expenses which were not budgeted to Columbus Plastics were allocated based upon
      a variety of factors which include the size of the Columbus Plastics operation, the
      number of Columbus Plastics employees, and the identification of costs specifically
      attributable to Columbus Plastics. Management believes that the allocation method
      used is reasonable and reflective of Columbus Plastics' proportionate share of such
      expenses and is comparable to those that would have been incurred on a stand alone
      basis.

      The following summarizes the corporate costs (credits) allocated to Columbus Plastics
      which were not budgeted and recorded by Columbus Plastics. The amounts represent
      adjustments to budgeted expenses or allocations of Corporate and Truck Group
      marketing and administrative expense:

 9.    LABOR CONCENTRATION

       At October 31, 1995, Columbus Plastics had 343 manufacturing employees all of which
       were represented by the International Association of Machinists and Aerospace Workers
       ("IAM"). The collective bargaining agreement with the IAM expires on August 1, 1998.

10.    PROPOSED ACQUISITION

       On September 12, 1996 NITC entered into an Asset Purchase Agreement with Rymac
       Mortgage Investment Company ("RYMAC") to sell substantially all of the assets and
       liabilities of Columbus Plastics to a RYMAC subsidiary, Core Materials Corporation
       ("Core Materials"). RYMAC will then be merged into Core Materials. In consideration
       for the net assets, NITC will receive upon closing (1) $25,504,000, subject to post
       closing adjustments, payable by Core Materials in the form of a secured promissory
       note ("Secured Note") and (2) 4,264,000 shares of Core Materials common stock
       (subject to adjustment) which will represent approximately 45% of the total number of
       shares of Core Materials common stock then issued. The Secured Note will bear
       interest at the rate of 8% per annum and will be secured by a first priority lien
       upon and security interest in all of Columbus Plastics' assets. The Secured Note will
       be due in November 2006. The Asset Purchase Agreement allows NITC to receive in the
       future additional consideration in the form of an increase in the Secured Note based
       upon a multiple of the amount by which Core Materials' earnings before interest and
       taxes exceed established thresholds over a three year period.

       As a condition to the consummation of the acquisition, NITC and Core Materials will
       enter into a Comprehensive Supply Agreement (the "Supply Agreement") and a
       Transitional Services Agreement (the "Services Agreement"). Under the terms of the
       Supply Agreement, for a period of five years, NITC will agree to purchase from Core
       Materials, and Core Materials will agree to sell to NITC at negotiated prices, which
       approximate fair value, all of NITC's original equipment and service requirements for
       Fiberglass Reinforced Parts using the Sheet Molding Composite process for components
       currently being manufactured by Columbus Plastics as they currently exist and are
       detailed in the Supply Agreement or as they may be improved or modified. On a pro
       forma basis, pursuant to the terms of the Supply Agreement, Columbus Plastics would
       have charged NITC for sales of its products approximately $43,600,000, $37,600,000,
       $33,400,000, and $27,100,000 for the years ended October 31, 1995, 1994 and 1993 and
       the nine months ended July 31, 1996, respectively. However, no minimum quantities of
       annual production of products or minimum purchase quantities are set forth or implied
       in the Supply Agreement, and no penalties will be imposed on NITC for volumes of
       products actually ordered by NITC below those quantities forecasted. Under the terms
       of the Services Agreement, NITC will provide financial reporting, accounting,
       budgeting and tax planning and return preparation services, computer services, and
       office support services to Core Materials and procure insurance on Core Materials'
       behalf, all for up to three years at fees based upon actual hours incurred, the cost
       of NITC personnel and related expenses and any costs incurred by NITC in providing
       such services and purchases. Management believes that the costs that will be incurred
       pursuant to the Services Agreement will approximate the amounts historically
       allocated to Columbus Plastics (see Note 8).

       The proposed transaction is subject to approval by RYMAC's shareholders and is
       expected to close by December 31, 1996.

       Based upon the terms of the proposed acquisition, for financial reporting and
       accounting purposes the transaction will be accounted for as a reverse acquisition
       whereby Columbus Plastics will be deemed to have acquired Core Materials. However,
       Core Materials will be the continuing legal entity and registrant for both Securities
       and Exchange Commission filing purposes and income tax reporting

F-8

COLUMBUS PLASTICS OPERATION

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

purposes. Consistent with reverse acquisition accounting treatment Core Materials
will carry forward the historical basis of the acquired assets and assumed
liabilities of Columbus Plastics and will revalue the basis of its net assets to fair
value. Should there be an additional contingent earn-out adjustment, it will be
accounted for by increasing the amount of the Secured Note, and by reducing the
amount of Core Materials' retained earnings.

CORE MATERIALS CORPORATION
NOTES TO BALANCE SHEET
OCTOBER 8, 1996

1. BASIS OF PRESENTATION

Core Materials Corporation (the "Company"), a Delaware corporation, a wholly-owned subsidiary of RYMAC Mortgage Investment Corporation ("RYMAC") was incorporated on October 8, 1996 and was formed for the purpose of merging with RYMAC and acquiring substantially all of the assets and liabilities of Navistar International Transportation Corp.'s ("Navistar") business currently conducted by Navistar at 800 Manor Park Drive, Columbus, Ohio, primarily relating to the manufacture, marketing and sale of fiberglass reinforced plastic component parts ("Columbus Plastics"), in exchange for stock and a secured promissory note of the Company. Based upon the terms of the proposed acquisition, for financial reporting and accounting purposes the transaction will be accounted for as a reverse acquisition whereby Columbus Plastics will be deemed to have acquired the Company. However, the Company will be the continuing legal entity and registrant for both Securities and Exchange Commission filing purposes and income tax reporting purposes. The Company's only activity has been the issuance of common stock and the receipt of cash.

2. RESTRICTIONS ON THE TRANSFER OF COMMON STOCK

Anti-takeover Measures: The Company's Certificate of Incorporation and By-laws contain certain provisions designed to discourage specific types of transactions involving an actual or threatened change of control of the Company. These provisions, which are designed to make it more difficult to change majority control of the Board of Directors without its consent, include the following:

Removal of Directors--This provision provides that a director of the Company may be removed with or without cause only upon the vote of the holders of at least 80% of the voting power of the outstanding shares of capital stock entitled to vote generally in the election of directors.

Supermajority Approval--This provision requires that a merger and certain other transactions (as outlined in the Certificate of Incorporation) be approved by the affirmative vote of the holders of at least 66 2/3% of the then outstanding shares of the Company's common stock. Such affirmative vote is required notwithstanding the fact that no vote may be required, or that a lesser percentage may be specified by law.

Amendments--This provision requires that any amendment to the provisions relating to the removal of Directors be approved by the holders of at least 80% of the then outstanding shares of voting stock, and any amendment to provisions requiring the approval of the holders of at least 66 2/3 of the then outstanding shares of voting stock be approved by the holders of at least 66 2/3 of the then outstanding shares of voting stock.

Restrictions on Transfer: The Company's Certificate of Incorporation also contains a provision (the "Prohibited Transfer Provision") designed to help assure the continued availability of RYMAC's substantial net operating losses and capital loss carryforwards (NOLs) following the merger and acquisition by seeking to prevent an "ownership change" as defined under current Treasury Department income tax regulations. Under the Prohibited Transfer Provision, if a stockholder transfers or agrees to transfer stock, the transfer will be prohibited and void to the extent that it would cause the transferee to hold a "Prohibited Ownership Percentage" (as defined in the Company's Certificate of Incorporation, but generally, means direct and indirect ownership of 4.5% or more of the Company's common stock) or if the transfer would result in the transferee's ownership increasing if the transferee had held a Prohibited Ownership Percentage within the three prior years or if the transferee's ownership percentage already exceeds the Prohibited Ownership Percentage under applicable Federal income tax rules. The Prohibited Transfer Provision does not prevent transfers of stock between persons who do not hold a Prohibited Ownership Percentage.

3. STOCK OPTION PLAN

At the time of the consummation of the merger, each outstanding option to purchase shares of RYMAC's common stock granted under any of RYMAC's previous stock option plans will be deemed amended to constitute an option to acquire, at the same price per share, the same number of shares of the Company's common stock. Pursuant to the merger, the holder of a former RYMAC option will be entitled to the same number of shares as would have been received had such holder exercised the option in full immediately prior to the consummation of the merger (not taking into account whether such RYMAC option was in fact exercisable at such time).

As of October 8, 1996, all of the outstanding RYMAC common stock options, representing 260,000 shares of common stock, were held by the executive officers and directors of RYMAC, 210,000 of which represent vested options and 50,000 of which represent non-vested options at that date. The non-vested options vest at the earlier of (i) the consummation of the proposed acquisition and (ii) July 1, 1997.

4. SUBSEQUENT EVENT

Effective November 6, 1996, the Company's Certificate of Incorporation was amended to, among other things, reduce the total number of shares of common stock which the Company shall have authority to issue from 50,000,000 to 20,000,000 shares.

(iv) except for those expressly accrued for and reflected on the Closing Date Balance Sheet or as otherwise provided in Section 8, any obligation or liability of Seller with respect to the Seller Plans;

(ii) above; and

(vi) any other obligation or liability with respect to or arising out of any Products, the Assets or the conduct of the Plastics Business prior to the Closing Date that are not Assumed Liabilities.

(f) Purchase Price. The purchase price (the "Purchase Price") for the Assets shall be:

(i) $25,504,000 subject to adjustment as provided in Section 1(g), payable to Seller at the Closing by delivery of a secured promissory note (the "Buyer Note") in the form of Exhibit A attached hereto (with such changes thereto and to the related documentation as may be reasonably requested by the parties providing the financing to the Buyer under the Credit Agreement (as defined in the Buyer Note) and which are acceptable to Seller in its sole discretion); provided that Buyer shall reduce the principal amount of the Buyer Note by delivering to Seller at Closing by wire transfer of immediately available funds an amount equal to such reduction pursuant to financing arrangements that, in the opinion of Buyer and Seller, would not reasonably be expected to have a material adverse effect on the ability of Buyer to secure loans for working capital and project finance use after the Closing; and

(ii) 4,264,000 shares of Buyer's Common Stock, par value $.01 per share (the "Common Stock") representing approximately 45% of the total number of shares of the Common Stock issued and outstanding on a fully diluted basis after giving effect to the transactions contemplated hereby and the payment of any fees contemplated by Section 22.

(g) Purchase Price Adjustment.

(i) If Net Tangible Assets as of the Closing Date exceeds Net Tangible Assets as of January 31, 1996, the amount of such excess shall be paid to Seller, at Seller's option by (A) the issuance by Buyer to Seller of additional shares of the Common Stock (valued, for purposes of this adjustment only, at $2.50 per share) by delivery of certificates representing such shares of the Common Stock, duly endorsed in blank or accompanied by stock powers duly endorsed in blank in proper form for transfer, with appropriate transfer stamps, if any, affixed thereto, provided that the aggregate amount of shares of the Common Stock issued to Seller by Buyer pursuant to this Section 1(g)(i), together with the shares of the Common Stock referred to in Section 1(f)(ii) that are to be issued to Seller by Buyer at the Closing, may, subject to Section 1(g)(iii), not exceed 45% of the total number of shares of the Common Stock issued and outstanding on a fully diluted basis after giving effect to the transactions contemplated hereby and the payment of any fees contemplated by Section 22, (B) an increase in the principal amount of the Buyer Note delivered at the Closing by delivery of an amended Buyer Note increased in principal amount

I-5

by the amount of such increase, in exchange for the Buyer Note delivered at Closing which amended Buyer Note shall be identical to the Buyer Note delivered at Closing except for the principal amount of such Buyer Note, or
(C) a combination of any or all of the options described in clauses (A) or (B) above. If Net Tangible Assets on January 31, 1996 exceeds Net Tangible Assets as of the Closing Date, the principal amount of the Buyer Note delivered at the Closing shall be decreased by the amount of such excess by delivery of an amended Buyer Note reduced in principal by the amount of such decrease, in exchange for the Buyer Note delivered at Closing which amended Buyer Note shall be identical to the Buyer Note delivered at Closing except for the principal amount of such Buyer Note. For purposes hereof "Net Tangible Assets" means, as of the Closing Date, the amount reflected as (Total Assets minus Intangible Assets) minus (Total Liabilities minus Intangible Liabilities) on the Closing Date Balance Sheet, and as of January 31, 1996 means the amount reflected as (Total Assets minus Intangible Assets) minus (Total Liabilities minus Intangible Liabilities) on Seller's books of the Plastics Business on such date. Net Tangible Assets as of January 31, 1996 is $25,969,000.

(ii) The adjustment described in Section 1(g)(i) shall be effected no later than seven business days after preparation and final determination, pursuant to this Section 1(g)(ii), of the Closing Date Balance Sheet. Within 45 days after the Closing Date, Seller shall prepare and deliver to Buyer based upon the books and records of the Plastics Business and consistent with past practices, a balance sheet of the Plastics Business (including footnotes thereto) (the "Closing Date Balance Sheet"), as of the Closing Date. Buyer and its authorized representatives shall be entitled to review the Closing Date Balance Sheet and the books, records and work papers of the Seller used to prepare such Closing Date Balance Sheet. If Buyer disagrees with any item on the face of the Closing Date Balance Sheet, Buyer shall notify Seller in writing of such disagreement (stating the reasons therefor) within 30 days after Buyer's receipt of the Closing Date Balance Sheet from Seller, and Buyer and Seller shall attempt to resolve such disagreement. If Buyer does not provide such notice within such 30 days, the Closing Date Balance Sheet shall be deemed to be the initial balance sheet submitted by Seller under this Section 1(g)(ii) for all purposes of this Agreement, and Net Tangible Assets as of the Closing Date shall be the amount reflected on the Closing Date Balance Sheet. If Buyer and Seller are unable to resolve any disagreement (with respect to which timely notice of such disagreement has been provided) within 15 days after Seller receives such notice of disagreement, Buyer and Seller shall submit the disagreement to a national independent public accounting firm acceptable to Buyer and Seller. If Buyer and Seller are unable to agree upon the selection of such firm within 20 days after Seller receives the above notice of disagreement, an accounting firm of national reputation will be selected within five days thereafter by lot after eliminating (A) Deloitte & Touche LLP (Seller's independent accountants), (B) Ernst & Young LLP (Buyer's independent accountants) and (C) one additional accounting firm for each of Buyer and Seller, should either Buyer or Seller or both, find such accounting firm(s) to be objectionable. Buyer and Seller shall cause the accounting firm so selected, within 15 days after its selection, to resolve such disagreement, which resolution shall be binding on the parties, and the Closing Date Balance Sheet shall be so finally adjusted in accordance with such resolution for all purposes of this Agreement. The fees and expenses of such accounting firm shall be paid 100% by Buyer unless Net Tangible Assets as determined pursuant to this Section 1(g)(ii) is not within 20% of the Net Tangible Assets reflected on the initial balance sheet submitted by Seller under this Section 1(g)(ii), in which case, the fees and expenses of such accounting firm shall be paid one-half by Buyer and one-half by Seller.

(iii) In the event that at any time within 3 years prior to the Closing any Person(s) or Public Group(s) was (were) or became Five Percent Shareholder(s) of Buyer and the effect of such Five Percent Shareholder(s) together with the issuance of shares of Buyer's Common Stock to Seller pursuant to Section 1(f) (ii) and Section 1(g)(i) would be to cause a 49 Percentage Point Increase (such event being herein a "Triggering Event"), then the Purchase Price as determined under clauses (i) and (ii) of Section
1(f) (as adjusted pursuant to Section 1(g)(i) and (vi)) shall be adjusted, effective as of the Closing, as follows (the "Adjustment Based on Closing Date Ownership"):

(A) the $25,504,000 payment under Section 1(f)(i) (as adjusted pursuant to
Section 1(g)(i)) shall be increased by an amount equal to the sum of
(x) to the extent that Seller's ownership of Common Stock of Buyer effective as of the Closing, would, on account of the operation of this Sec-

I-6

tion 1(g)(iii) be reduced below 40% of the total shares of Common Stock of Buyer issued and outstanding as of the effective time of Closing, the product derived by multiplying $7.50 times the total number of Excess Shares (as defined in subparagraph (B) below) that, if retained by Seller, would cause Seller's ownership of Common Stock of Buyer effective as of the Closing, to equal 40% of the total shares of Common Stock of Buyer issued and outstanding as of the effective time of Closing plus (y) the product derived by multiplying the total number of all remaining Excess Shares times $5.00, and

(B) the number of shares of Buyer's Common Stock deliverable to Seller under Section 1(f)(ii) and Section 1(g)(i) (collectively the "Delivered Shares") shall be reduced reducing first shares deliverable under
Section 1(f)(ii) and then shares deliverable under Section 1(g)(i) by such number of shares (the "Excess Shares") such that the number of shares then deliverable under such Sections when taken together with ownership changes of all Five Percent Shareholder(s) of Buyer within the 3 year period prior to Closing would be one share short of causing a 49 Percentage Point Increase.

All Excess Shares shall be void ab initio, with the effect that the Excess Shares shall be treated as never having been issued. Seller shall immediately return to Buyer all certificates evidencing Excess Shares, together with all dividends and distributions at any time received by Seller with respect to Excess Shares.

(iv) For purposes of this Agreement:

"Five Percent Shareholder" shall mean any Person or Public Group whose ownership in Buyer would cause such Person or Public Group to be a "5-percent shareholder" of Buyer within the meaning of Treasury Regulations Section 1.382-2T(g)(1)(i) or (ii);

"49 Percentage Point Increase" shall mean an increase of 49 percentage points or more of the Stock of Buyer owned by Five Percent Shareholders over the lowest percentage of Stock owned by such 5-percent shareholders at any time during the three-year period preceding the Closing, such determination to be made in accordance with Treasury Regulations Section 1.382-2T(c) as if the Closing Date were a "testing date."

"Public Group" shall have the meaning set forth in Treasury Regulations
Section 1.382-2T(f)(13).

"Stock" shall mean all classes of stock of Buyer, all options (as defined in Treasury Regulations Section 1.382-4(d)(g)) to acquire stock of Buyer that must be treated as exercised pursuant to Treasury Regulation Section 1.382-4(d)(2) and all other interests that would be treated as stock in Buyer pursuant to Treasury Regulations Section 1.382-2T(f)(18)(iii).

(v) From and after the date of this Agreement, Buyer, as soon as it becomes aware of any facts or circumstances which may bear upon the existence of a Five Percent Shareholder and/or 49 Percentage Point Increase (including knowledge of any report on Schedule 13D or 13G filed under the Securities Exchange Act of 1934, as amended, with respect to Buyer), shall promptly inform Seller thereof in writing. Seller's determination at any time as to the existence of a Five Percent Shareholder and/or 49 Percent Point Increase, the occurrence of a Triggering Event and the calculation of the Adjustment Based on Closing Date Ownership, based on the facts and circumstances known to it at such time, shall be binding on the parties, subject to Section 30, and Seller's right from time to time to revise its determination based on the discovery of new facts and circumstances (such determination by Seller, as from time to time revised by Seller, is herein the "Closing Date Ownership Determination"). Seller shall promptly notify Buyer in writing of any Closing Date Ownership Determination, which notice shall set forth, in reasonable detail, Seller's basis for determining the occurrence of a Triggering Event and the calculation of the Adjustment Based on Closing Date Ownership (herein a "Notice of Closing Date Ownership Determination"). In the event that a Triggering Event is determined to exist pursuant to a Notice of Closing Date Ownership Determination (regardless of whether such Notice is given before or after Closing and whether one or more other Notices of Closing Date Ownership Determination have previously been given), the Adjustment Based on Closing Date Ownership in respect of such Triggering Event shall be effective as of the Closing based on the ownership of Stock as of the time of Closing as determined pursuant to such Notice. Notwithstanding anything herein to the contrary, no further Notice of Closing Date Ownership Determination shall be given by Seller after March 31, 1997

I-7

("Outside Notice Date"), so that the Closing Date Ownership Determination as in existence on the Outside Notice Date and the Adjustment Based on Closing Date Ownership pursuant to such Determination shall be final and binding on the parties. Prior to the Outside Notice Date, neither Seller nor any transferee of the Delivered Shares shall transfer any of the Delivered Shares other than to persons who agree to take the Delivered Shares subject to the provisions of Sections 1(g)(iii), (iv) and (v) (for which purpose, Excess Shares at any time shall first be reduced from any remaining Delivered Shares then held by Seller and/or its affiliates, and thereafter shall be reduced from any Delivered Shares then held by transferees on a pro rata basis). The certificates evidencing the Delivered Shares shall bear a legend reflecting that the Delivered Shares are subject to the restrictions set forth in Sections 1(g)(iii), (iv) and (v) of this Agreement; provided that such legend shall be removed at any time after the Outside Notice Date upon request by any holder of the Delivered Shares. The provisions of Sections 1(g)(iii), (iv) and (v) shall not be construed to limit Seller's right not to consummate the transactions contemplated by this Agreement if the condition set forth in Section 3(b)(xviii) has not been satisfied.

(vi) If Buyer's earnings before interest and taxes ("EBIT") for Buyer's fiscal year ended December 31, 1997 exceed $6,512,000 ("Forecasted EBIT"), an amount equal to the product of (x) the excess amount ("1997 Excess EBIT") multiplied by (y) 5.55 shall be paid to Seller by an increase in the principal amount of the Buyer Note by delivery of an Amended Buyer Note increased in principal amount by such amount. If Buyer's EBIT for Buyer's fiscal year ended December 31, 1998 exceeds Forecasted EBIT, an amount equal to the product of (x) the excess amount ("1998 Excess EBIT") less the 1997 Excess EBIT multiplied by
(y) 4.50 shall be paid to Seller by an increase in the principal amount of the Buyer Note by delivery of an Amended Buyer Note increased in principal amount by such amount. If Buyer's EBIT for Buyer's fiscal year ended December 31, 1999 exceeds the Forecasted EBIT, an amount equal to the product of (x) the excess amount less the 1998 Excess EBIT multiplied by (y) 2.75 shall be paid to Seller by an increase in the principal amount of the Buyer Note by delivery of an Amended Buyer Note increased in principal amount by such amount. For purposes of this Section 1(g)(vi), Buyer's EBIT shall be calculated using the same methodology and based on the same types and categories of expenses as used in the calculation of Forecasted EBIT, which categories and types of expenses and methodology are more particularly described in Schedule 1(g)(vi) attached hereto, and shall expressly exclude any and all other types or categories of expenses. Notwithstanding anything herein to the contrary, the total amount by which the principal amount of the Buyer Note may be increased pursuant to this
Section 1(g)(vi) shall not exceed $24,496,000 in the aggregate.

(vii) The adjustment described in Section 1(g)(vi) shall be effected no later than 7 business days after preparation and final determination, pursuant to this Section 1(g)(vii), of Buyer's EBIT for each such fiscal year. Within 90 days after the close of each such fiscal year, Buyer shall prepare and deliver to Seller based on the books and records of Buyer and calculated in accordance with Section 1(g)(vi) an audited balance sheet and statement of income for such fiscal year prepared in accordance with generally accepted accounting principles, together with a certificate ("EBIT Certificate") dated as of the end of such fiscal year and signed by the chief financial officer of Buyer certifying the amount of Buyer's EBIT for such fiscal year, the amount of any excess over Forecasted EBIT and the amount to be paid to Seller pursuant to
Section 1(g)(vi) above. Seller and its authorized representatives shall be entitled to review the EBIT Certificate and the books, records and work papers of the Buyer used to prepare such EBIT Certificate. If Seller disagrees with any item on the face of the EBIT Certificate, Seller shall notify Buyer writing of such disagreement (stating the reasons therefor) within 30 days after Seller's receipt of such EBIT Certificate from Buyer, and Seller and Buyer shall attempt to resolve such disagreement. If Seller does not provide such notice within such 30 days, the EBIT Certificate for such fiscal year shall be deemed accepted by Seller and for purposes of Section 1(g)(vi) above Buyer's EBIT for such fiscal year shall be the amount reflected on such EBIT Certificate. If Seller and Buyer are unable to resolve any disagreement (with respect to which timely notice of such disagreement has been provided) within 15 days after Buyer receives such notice of disagreement, Seller and Buyer shall submit the disagreement to a national independent public accounting firm acceptable to Buyer and Seller. If Buyer and Seller are unable to agree upon the selection of such firm within 20 days after Buyer receives the above notice of disagreement, an accounting firm of national reputation shall be selected within 5 days thereafter by lot after eliminating (a) Deloitte & Touche LLP (Seller's independent accountants) and (b) Ernst & Young LLP (Buyer's independent accountants) and (c) one additional accounting firm for each of Buyer and Seller, should either Buyer or Seller or both, find such accounting firm to be objectionable. Buyer and Seller shall

I-8

cause the accounting firms so selected, within 15 days after its selection, to resolve such disagreement, which resolution shall be binding on the parties, and the Buyer's EBIT for such fiscal year shall be so finally adjusted in accordance with such resolution for purposes of Section 1(g)(vi) above. The fees and expenses of such accounting firm shall be paid 100% by Seller unless Buyer's EBIT for such fiscal year as determined pursuant to this Section 1(g)(vii) is not within 20% of the Buyer's EBIT reflected on Buyer's initial EBIT Certificate for such fiscal year submitted by Buyer under this Section 1(g)(vii), in which case, the fees and expenses of such accounting firm shall be paid one-half by Buyer and one-half by Seller.

(h) Allocation of Purchase Price. As promptly as practicable following the date hereof, but in any event within ten business days prior to the Closing Date, Buyer shall deliver to Seller its reasonable, good faith determination of the fair market value of the Assets, which determination shall be made in accordance with applicable tax laws and shall be subject to Seller's consent (which consent shall not be unreasonably withheld or delayed). Buyer and Seller shall then set forth such determination on Schedule 1(h) attached hereto, which shall include an allocation of the Purchase Price among the Assets on the basis of the fair market values thereof and which, if necessary, shall be amended to take into account any adjustments which may be required by Section 1(g). For tax purposes, the Purchase Price shall be allocated among the Assets (which allocation shall be consistent with the allocation set forth on Schedule 1(h)) and such Purchase Price shall be allocated in accordance with Section 1060 of the Code. Neither Buyer nor Seller, nor any of their respective affiliates, shall take any position (whether in financial statements, audits, tax returns or otherwise) which is inconsistent with the allocation of the Purchase Price, taking into account any adjustments which may be required by Section 1(g), unless required to do so by applicable law. The parties shall exchange drafts of any information returns required by Section 1060 of the Code and any similar state statute at least 60 days prior to filing such returns and shall discuss in good faith any modifications suggested by the receiving party. For purposes of this Agreement, the term "Code" shall mean the Internal Revenue Code of 1986, as amended, and any reference to any particular Code provision shall be interpreted to include any revision of or successor to such provision regardless of how numbered or classified.

2. Closing.

The closing (the "Closing") of the purchase and sale of the Assets and the assumption of the Assumed Liabilities shall be held at the offices of Seller, at 10:00 a.m., local time, on the first Monday or fiscal month-end (determined with reference to Seller's accounting policies) that is at least three business days following satisfaction or, if permissible, waiver of the conditions to Closing set forth in Sections 3(a) and 3(b).

Seller and Buyer shall cooperate with each other regarding, and shall use their reasonable efforts to cause, the sale to Buyer of all of the Assets on the Closing Date on the terms and conditions set forth in this Agreement, and to otherwise consummate the transactions contemplated hereby; provided, however, that such cooperation and reasonable efforts by Seller shall not include any requirement of the Seller Entities to expend money, commence any litigation or offer or grant any accommodation (financial or otherwise) to any third party. Nothing in this Agreement shall be construed as an attempt or agreement to assign (x) any Contract which is nonassignable without the consent of the other party or parties thereto unless such consent shall have been obtained (subject to the right of Buyer under Sections 3(a)(iv) and 3(a)(v) and the right of Seller under Section 3(b)(iii)) or (y) any Contract or claim as to which the remedies for the enforcement thereof enjoyed by Seller would not pass to Buyer as an incident of the assignments provided for by this Agreement. The Purchase Price shall not be subject to adjustment by reason of the fact that any Contracts or claims may not be assigned to Buyer under the circumstances described in clauses (x) and (y) above. Any Contract which is not properly assigned to Buyer because of the failure to obtain a required consent shall be governed by, and subject to the provisions of, Section 8(b).

I-25

retirement benefits under the Navistar International Transportation Corp. Retirement Health Benefit and Life Insurance Plan which was established by Seller pursuant to Shy v. Navistar. Buyer will reimburse Seller for its cost of such coverage for any IAM-represented employees hired by Buyer on a pro rata basis based on the time of service with Buyer compared to the total time of service with Seller and Buyer. Other than Shy postretirement benefits for retirement-eligible employees, Buyer assumes all liability for any postretirement benefit liability arising from the transactions contemplated by this Agreement or the employment of any IAM-represented employee hired by Buyer, and Seller will not assume any such liability or reimburse Buyer for any amount of such liability. In the event that Seller is liable for any amount for which Buyer is not also liable for any postretirement benefit for any IAM-represented employee hired by Buyer, Buyer will reimburse Seller for a pro rata portion of Seller's liability based on the time of the employee's service for Buyer compared to the total time of service with Seller and Buyer. If Buyer's collective bargaining agreement with the IAM provides for the establishment of a Section 401(k) plan for the employees subject to the agreement, the agreement shall permit, and Buyer shall cause its Section 401(k) plan to accept a trust-to-trust transfer of the assets and liabilities (including participant loans and amounts payable to alternate payees under qualified domestic relations orders, but not including any in-kind transfer of any Navistar International Corporation stock) of Seller's Section 401(k) plan, with respect to the IAM-represented employees hired by Buyer, valued as of such date as Seller may reasonably determine. Buyer shall establish its
Section 401(k) plan timely and in a form meeting the qualification requirements of the Internal Revenue Code and provide such evidence to Seller as Seller may reasonably request as to such qualification so as to permit Seller to transfer timely the assets and liabilities relating to the IAM-represented employees hired by Buyer.

(ii) Buyer agrees that it shall comply with the requirements of
Section 4204 of ERISA with respect to each Multiemployer Plan described on Schedule 4(k) and, in that regard, Buyer agrees to (A) contribute to each such Multiemployer Plan with respect to the operations of Buyer for substantially the same contribution base units (as set forth in the collective bargaining agreement in effect immediately prior to the Closing Date between Seller and the IAM) for which Seller had an obligation to contribute to each such Multiemployer Plan; (B) provide to each such Multiemployer Plan for a period of five years commencing with the first plan year beginning after the Closing Date a bond or other security as described in Section 4204(a)(1)(B) of ERISA (unless such requirement has been released or waived in accordance with procedures consistent with
Section 4204 of ERISA), which security, if provided, will be paid to a Multiemployer Plan if Buyer withdraws from the Multiemployer Plan or fails to make a contribution to the Multiemployer Plan when due at any time during the first five years beginning after the Closing Date; and (C) pay when due any withdrawal liability assessed as a result of any complete or partial withdrawal by Buyer during the five-year period calculated in accordance with Section 4204(b)(1) of ERISA. Seller agrees that if, during the first five plan years beginning after the Closing Date, Buyer withdraws in a complete or partial withdrawal, Seller will be secondarily liable for any withdrawal liability it would have had to the Multiemployer Plan with respect to Seller's operations as of the Closing Date but for the provisions of this Section 8(m). Upon its dissolution or liquidation, Seller will provide each Multiemployer Plan set forth on Schedule 4(k) with such security as is required pursuant to Section 4204(a)(3)(A) of ERISA, unless a release or waiver of such security shall be granted by the Multiemployer Plan or the PBGC consistent with the requirements of Section 4204(a)(3)(A) of ERISA. For purposes of the immediately preceding sentence, the term "Seller" shall mean the Seller and any of its affiliates which meet the definition of "single employer" for purposes of Section 3(37) of ERISA. Seller and Buyer agree to take all actions necessary or desirable to assure that no withdrawal liability arises with respect to each such Multiemployer Plan by reason of the transactions contemplated by this Agreement.

(m) Employee Benefit Plans for Non-Represented Employees.

(i) Seller shall retain all assets of, and liabilities under, the Seller Plans relating to non-represented employees, and no such Seller Plan or any assets or liabilities thereof shall be transferred to, or assumed by, Buyer. Buyer shall establish Employee Benefit Plans to cover the Hired Employees as of the Closing Date that are identical in all material respects to the Seller Plans that covered the Hired Employees immediately prior to the Closing Date; provided, however, that Buyer shall not be obligated under this

I-26

Agreement to establish or maintain any Employee Welfare Benefit Plan for the benefit of the Hired Employees that provides postretirement medical, dental or life insurance benefits. Buyer shall have no obligation to establish any "New Hire Plans" for any Hired Employee, or any provisions of Sellers Plans that specifically relate to "New Hires".

Buyer shall establish its Section 401(k) plan timely and in a form meeting the qualification requirements of the Code and provide such evidence to Seller as Seller may reasonably request as to such qualification so as to permit Seller to transfer timely the assets and liabilities relating to the Hired Employees.

(ii) Buyer shall waive pre-existing condition requirements, evidence of insurability provisions, waiting period requirements or any similar provisions under any Employee Benefit Plan or compensation arrangements maintained or sponsored by or contributed to by Buyer for each Hired Employee after the Closing Date.

(iv) Seller and Seller's Plans shall be responsible for expenses covered by Seller's medical plans; provided, however, that such expenses were incurred prior to the Closing Date. Buyer and Buyer's plans shall be responsible for expenses covered by Buyer's medical plans for all health and accident claims relating to the Hired Employees (including, without limitation, claims arising out out of medical conditions existing at or prior to the Closing Date) and all Incidents relating to the Hired Employees that occur or arise on or after the Closing Date. For purposes of the immediately preceding sentence, the term "Incidents" includes accident, death, disabilities, diseases and injuries. Seller and Buyer recognize that certain Hired Employees who become entitled to a pension benefit other than a deferred vested benefit under the Navistar International Transportation Corp. Retirement Plan for Salaried Employees are eligible for postretirement benefits under the Navistar International Transportation Corp. Retirement Health Benefit and Life Insurance Plan which was established by Seller pursuant to Shy v. Navistar. Buyer will reimburse Seller for its cost of such coverage of each such Hired Employee on a pro rata basis based on the time of service with Buyer compared to the total time of service with Seller and Buyer. Other than the Shy postretirement benefits for such Hired Employees, Buyer assumes all liability for the post retirement benefit liability arising from this transaction or the employment of any Hired Employee, and Seller will not assume any such liability or reimburse Buyer for any amount of such liability. Notwithstanding any other provision of this Agreement, Buyer will establish and maintain, or will maintain, any plan or plans necessary to satisfy such liability. In the event that Seller is liable for any amount for which Buyer is not also liable for any postretirement benefit for any Hired Employee, Buyer will reimburse Seller for a pro rata portion of Seller's liability based on the time of the employee's service for Buyer compared to the total time of service with Seller and Buyer.

(v) Except as otherwise provided in Section 8(n)(x) below, Seller shall recognize solely for purposes of vesting under any qualified pension plan of accrued benefits under the Seller Plans the service of each Hired Employee with Buyer on and after the Closing Date.

(vi) Buyer shall recognize for purposes of participation, eligibility to commence receiving benefits (including early retirement, disability and other subsidized benefits), vesting and benefit accruals under its Employee Benefit Plans, the service of each Hired Employee with Seller or Seller's affiliates prior to the Closing Date and the service of each Hired Employee with all other prior employers to the extent such service is credited under the Seller Plans; provided, however, that Buyer will be permitted to offset

I-27

the accrued benefits of each Hired Employee under each Employee Benefit Plan of Buyer that is an Employee Pension Benefit Plan by such Hired Employee's vested accrued benefits, if any, as of the Closing Date under each corresponding Seller Plan.

(vii) Seller shall be responsible for satisfying obligations under
Section 601 et seq. of ERISA and Section 4980B of the Code, to provide continuation coverage to or with respect to any employee of Seller as of the Closing Date in accordance with applicable law with respect to any "qualifying event" occurring on or prior to the Closing Date, including any "qualifying event" resulting from the Closing hereunder. Buyer shall be responsible for satisfying obligations under Section 601 et seq. of ERISA and Section 4980B of the Code, to provide continuation coverage to or with respect to any Hired Employee in accordance with applicable law with respect to any "qualifying event" which occurs after the Closing Date.

(viii) Seller shall be responsible for all salary accrued but not yet paid as of the Closing Date nor reflected on the Closing Date Balance Sheet and, if applicable, 1996 bonus accrued but not yet paid as of the Closing Date nor reflected on the Closing Date Balance Sheet (in an amount equal to the pro rata portion of such bonus allocable to the period prior to the Closing Date) with respect to the Hired Employees, and Buyer shall be responsible for the pro rata portion of such bonus allocable to the period on and after the Closing Date.

(ix) Seller shall pursuant to Article II of the Navistar International Transportation Corp. Income Protection Plan (the "IPP") extend eligibility for pension grow-in to each Hired Employee to the extent such employee would be eligible for pension grow-in under the IPP if such employee were not hired by Buyer; provided that grow-in will not be provided unless the Hired Employee either (1) continue employment with Buyer until attaining retirement age under the Navistar International Transportation Corp. Retirement Plan for Salaried Employees, or (2) terminates employment with Buyer under circumstances that if the termination were from Seller rather than from Buyer the grow-in provisions of the IPP would apply to such termination. No other benefits under the IPP are being extended to any Hired Employee, and no benefits are being provided under this provision to any Hired Employee who would not otherwise be eligible for pension grow-in under the terms and conditions of the IPP.

(n) Miscellaneous Employee Benefit Matters.

(i) Seller shall remain responsible for all workers' compensation claims of Hired Employees and IAM-represented employees hired by Buyer with respect to which all events giving rise to the claim in each case have occurred prior to the Closing Date without regard to the date on which such claims are actually reported; provided, however, that Buyer shall be responsible for all such claims accrued for and reflected on the Closing Date Balance Sheet. Buyer shall be responsible for all other workers' compensation claims of Hired Employees and IAM-represented employees hired by Buyer, including workers' compensation claims with respect to which some, but not all, events giving rise to the claim in each case have occurred prior to the Closing Date.

(ii) Buyer shall indemnify, defend and hold the Seller Entities harmless from and against any Losses (as defined in Section 10(a)) for severance liability suffered by any of the Seller Entities with respect to any Hired Employee or IAM-represented employee hired by Buyer, which employee is terminated by Buyer on or after the Closing Date.

(iii) Seller and Buyer agree that the responsibilities for payroll taxes with respect to the Hired Employees and IAM-represented employees hired by Buyer shall be assigned under the Alternative Procedure described in Section 5 of Rev. Proc. 84-77.

(iv) Buyer represents that it does not currently contemplate a plant closing or mass lay-off of Hired Employees and/or IAM-represented employees hired by Buyer, or any terminations that, in the aggregate, would constitute, within one year following the Closing, a mass lay-off of Hired Employees and/or IAM-represented employees hired by Buyer. Buyer shall indemnify and defend the Seller Entities and hold each of them harmless from and against any Losses which may be incurred or suffered by any of them under the Worker Adjustment and Retraining Notification Act or any similar state law arising out of, or relating to, any actions taken by Buyer on or after the Closing Date.

I-28

(vi) Effective as of the Closing Date, Buyer shall terminate the SEP in accordance with applicable law.

(o) By-Laws of Buyer. Seller covenants and agrees that for the period from the Closing Date through the sixth anniversary thereof, it shall not vote in favor of or otherwise directly or indirectly support any amendment of the provisions of Buyer's By-Laws relating to the indemnification of officers and directors of Buyer which would have an adverse effect on present or former officers or directors of Buyer (except to the extent that withholding any such vote would be in contravention of any applicable law).

(p) No Authority To Bind. Buyer covenants and agrees that from and after the Closing Date, without the prior written consent of Seller, it will not hold itself out as an affiliate of Seller or take any actions or omit to take any actions which would have the effect of creating or making binding any obligation on Seller.

(q) Records. Buyer and Seller agree that Seller may maintain copies of any books and records and other financial data (collectively, the "Records") that are included in the Assets and that are delivered to Buyer hereunder. Buyer agrees to maintain such Records for a period of not less than ten years from the Closing Date (plus any additional time during which a party has been advised that (A) there is an ongoing tax audit with respect to periods prior to the Closing Date, or (B) such period is otherwise open to assessment). During such period, Buyer agrees to give Seller and its representatives reasonable cooperation, access (including copies) and staff assistance, as needed, during normal business hours and upon reasonable notice, with respect to the Records delivered to Buyer hereunder, and Seller agrees to give Buyer and its representatives reasonable cooperation, access and staff assistance, as needed, during normal business hours and upon reasonable notice, with respect to the books and records and other financial data relating to the Plastics Business and retained by the Seller Entities, in each case as may be necessary for general business purposes, including the preparation of tax returns and financial statements, the management and handling of tax audits and reviewing the calculation (and preparing its own calculation) of the post-closing adjustments described in Section 1(g); provided that such cooperation, access and assistance does not unreasonably disrupt the normal operations of Buyer or any of the Seller Entities. Buyer shall not destroy or otherwise dispose of the Records for the period set forth in the immediately preceding sentence without the written consent of Seller.

(r) Initial Board of Directors; Vacancies of Board. From and after the Closing Date and until the first annual meeting of the stockholders of Buyer following the Closing Date, the Buyer's board of directors shall be comprised of two representatives to be designated by Seller (the "Seller Directors"); two representatives to be designated by members of Buyer's existing board of directors (the "Buyer Directors"); and one representative to be mutually satisfactory to Seller and Buyer (the "Independent Director"). With respect to vacancies on the initial board of directors of Buyer which exist at any time prior to the first annual meeting of the stockholders of Buyer following the Closing Date (which annual meeting shall be no sooner than 12 months following the Closing Date), the Buyer Directors shall have all requisite authority to act on behalf of Buyer as a special committee of the Board of Directors of Buyer to fill vacancies created by the resignation or removal of a Buyer Director and the Seller Director shall have all requisite authority to act on behalf of Buyer as a special committee of the Board of Directors of Buyer to fill vacancies created by the resignation or removal of a Seller Director.

(s) Ordinary Conduct of Buyer. From the Closing to the Outside Notice Date, Buyer will cause the Plastics Business to be conducted in the ordinary course consistent with past practice of Seller and will make all reasonable efforts consistent with past practices of Seller to preserve its relationship with its third party customers and suppliers in connection with the Plastics Business. From the Closing to the Outside Notice Date, Buyer will not do any of the following without the prior written consent of Seller:

(i) make any material change in the conduct of the Plastics Business;

(ii) sell, lease, license or otherwise dispose of, any interest in any of its assets, except for sales of inventory in the ordinary course of business consistent with past practice of Seller;

(x) make capital expenditures or commitments therefor that aggregate in excess of $10,000;

(xi) made any charitable contributions or pledges;

(xii) hire any employees to perform services for Buyer or increase any compensation or other amounts payable to any employees;

(xiii) enter into any other material transaction or other transaction that is not in the ordinary course of business consistent with Seller's past practices; or

(xiv) enter into any agreement, whether in writing or otherwise, to do any of the foregoing.

9. Further Assurances.

From time to time, as and when requested by any party hereto, the other party hereto shall execute and deliver, or cause to be executed and delivered, all such documents and instruments and shall take, or cause to be taken, all such further or other actions (subject to the limitations set forth in Section 8(a) and Section 8(b)), as such other party may reasonably deem necessary or desirable to consummate the transactions contemplated by this Agreement.

10. Indemnification.

(a) Indemnification by Seller. Seller shall indemnify Buyer, its affiliates and each of their respective officers, directors, employees and agents and hold them harmless from any Loss suffered or incurred by any such indemnified party or to which any such indemnified party becomes subject to the extent directly or indirectly arising from (i)any breach of (or in the event any third party alleges facts that if true would mean Seller has breached) any covenant of Seller contained in this Agreement or the other agreements and instruments contemplated hereby; (ii) any Excluded Liability and (iii) any statements or information contained in the Definitive Proxy Statement/Prospectus relating to the Plastics Business or the Seller Entities requested by Buyer for inclusion in the Definitive Proxy Statement/Prospectus and supplied by Seller, provided Buyer presents such information in the Definitive Proxy Statement/Prospectus in conformity in form and substance with the information supplied by it to Seller.

(b) Indemnification by Buyer. Buyer shall indemnify each of Seller, its affiliates, officers, directors, employees and agents against and hold them harmless from any Loss suffered or incurred by any such indemnified party or to which any such indemnified party becomes subject to the extent directly or indirectly arising from (i) any breach of (or in the event any third party alleges facts that if true would mean Buyer has breached) any covenant of Buyer contained in this Agreement or the other agreements and instruments contemplated hereby, (ii) any Assumed Liability (other than any Loss of Seller solely in its capacity as a shareholder of Buyer arising from any Assumed Liability described in Section 1(d)(iv)) and (iii) any

I-30

discontinuance, suspension or modification of any Benefit Plans maintained by Buyer as contemplated by Section 3(b)(vii) hereof. Buyer shall also indemnify each of Seller, its affiliates, officers, directors, employees and agents against and hold them harmless from its Proportionate Share of any Loss suffered or incurred by Buyer or any of its subsidiaries from and after the Closing Date (including Losses suffered or incurred by Buyer to its present or former shareholders) (x) in respect of any actions, omissions, events, circumstances or state of facts existing or arising on, at or prior to the Closing Date or (y) arising in connection with any statements or information contained in the Definitive Proxy Statement/Prospectus (other than information relating to the Plastics Business or the Seller Entities requested by Buyer for inclusion in the Definitive Proxy Statement/Prospectus and supplied by Seller, provided Buyer presents such information in the Definitive Proxy Statement/Prospectus in conformity in form and substance with the information supplied to it by Seller); provided no indemnity will be made by Buyer in respect of (A) except as provided in clause (y) of this sentence, any acts, omissions, events, circumstances or state of facts existing or arising on, at or prior to the Closing Date relating to this Agreement, the matters referred to in the Buyer Resolutions (other than the Ancillary Agreements) or any of the transactions contemplated hereby or thereby, (B) any Loss suffered or incurred by Buyer or any of its subsidiaries from and after the Closing Date that arises from a liability that is specifically listed (but only up to the amount listed) on Schedule 3(b)(xv) or
(C) any inability of Buyer to be able to use the NOLs described in Sections
6(k)(ii) (I) and 6(k)(ii)(J) after the Closing. For purposes hereof, at the time of any Loss, the "Proportionate Share" of each of Seller, its affiliates, officers, directors, employees and agents shall be the ratio, expressed as a percentage, of the total number of shares of the Common Stock owned by such Persons at the time of such Loss divided by the total number of shares of the Common Stock issued and outstanding at the time of such Loss.

(c) Exclusive Remedy. Except in connection with the exercise of remedies for breaches of Sections 5(a), 7(a), 8(e) and 22, and except as otherwise provided in Section 1(g), the Ancillary Documents or the Related Documents (as defined in the Buyer Note), each of Buyer and Seller acknowledges and agrees that, from and after the Closing, its sole and exclusive remedy with respect to any and all claims relating to the subject matter of this Agreement and the other agreements contemplated hereby (other than tort claims of, or causes of action arising from, fraudulent misrepresentation) shall be pursuant to the indemnification provisions set forth in this Section 10. In furtherance of the foregoing, each of Buyer and Seller hereby waives, from and after the Closing, to the fullest extent permitted under applicable law, any and all rights, claims and causes of action (other than tort claims of, or causes of action arising from, fraudulent misrepresentation) it may have against each other relating to the subject matter of this Agreement and the other agreements contemplated hereby arising under or based upon any federal, state, local or foreign statute, law, ordinance, rule or regulation or otherwise, including without limitation, any cause of action for contribution or otherwise under the Comprehensive Environmental Response, Liability and Compensation Act, as amended, or any other federal, state, local or foreign law giving rise to liability for disposal or release of hazardous substances. Buyer further acknowledges and agrees that, (i) other than the representations and warranties of Seller specifically contained in this Agreement (which expire at the Closing), there are no representations or warranties of any of the Seller Entities or their representatives or any other Person either express or implied with respect to the Plastics Business, the Assets, the Real Property or the Assumed Liabilities and (ii) it shall have no claim or right to indemnification with respect to any information, documents or materials furnished by the Seller Entities or their representatives or any other Person or any of their officers, directors, employees, agents or advisors, including the Information Memorandum and any information, documents or material made available to Buyer in certain "data rooms," management presentations or any other form in expectation of the transactions contemplated by this Agreement. Nothing contained herein shall be deemed to limit or otherwise impair the ability of Seller to exercise its rights and remedies (x) as a stockholder of Buyer from and after the Closing Date, including, without limitation, the right to bring claims and causes of action against Buyer for matters arising or accruing after the Closing Date and (y) pursuant to Section 1(g).

(d) Losses Net of Insurance and Tax Benefit.

(i) The amount of any and all Losses under this Section 10 shall be determined net of any amounts recovered or recoverable by the indemnified party under insurance policies with respect to such Losses. Each party hereby waives, to the extent permitted under its applicable insurance policies, any subrogation

I-31

rights that its insurer may have with respect to any indemnifiable Losses. Any indemnity payment under this Agreement shall be treated as an adjustment to the Purchase Price for tax purposes.

(ii) If an indemnification obligation under this Section 10 arises in respect of any adjustment which results in any Tax benefit to Buyer or Seller (the "Benefitted Party"), any successor thereto or any affiliate thereof for any taxable period (or portion thereof) beginning and ending after the Closing Date which would not, but for such adjustment, be available, the Benefitted Party shall pay, or shall cause to be paid, to the party making such indemnification payment an amount equal to the actual Tax saving produced by such Tax benefit at the time such Tax saving is realized by the Benefitted Party, any successor thereto or any affiliate thereof. The amount of any such Tax saving for any taxable period shall be the amount of the reduction in Taxes payable to a taxing authority by the Benefitted Party, any successor thereto or any affiliate thereof with respect to such tax period as compared to the Taxes that would have been payable to a taxing authority by the Benefitted Party, any successor thereto or any affiliate thereof with respect to such tax period in the absence of such Tax benefit.

(e) Termination of Indemnification. The obligations to indemnify and hold harmless a party hereto, pursuant to Sections 10(a) and 10(b), shall terminate on the sixth anniversary of the Closing Date; provided, however, that such obligations to indemnify and hold harmless shall not terminate with respect to any item as to which the Person to be indemnified or the related party thereto shall have, prior to the sixth anniversary of the Closing Date, previously made a claim by delivering a written notice (stating in reasonable detail the nature of, and factual and legal basis for, any such claim for indemnification, and the provisions of this Agreement upon which such claim for indemnification is made) to the indemnifying party.

(f) Procedures Relating to Indemnification.

(i) In order for a party (the "indemnified party") to be entitled to any indemnification provided for under this Agreement with respect to any matter (including any matter in respect of, arising out of or involving a claim or demand made by any Person, firm, governmental authority or corporation against the indemnified party (a "Claim")), such indemnified party must notify the indemnifying party in writing, and in reasonable detail, of the Claim as promptly as reasonably possible after receipt by such indemnified party of notice of the Claim; provided, however, that failure to give such notification on a timely basis shall not affect the indemnification provided hereunder except to the extent the indemnifying party shall have been actually prejudiced as a result of such failure. Thereafter, the indemnified party shall deliver to the indemnifying party, within five business days after the indemnified party's receipt thereof, copies of all notices and documents (including court papers) received by the indemnified party relating to the Claim.

(ii) Upon receipt by either Buyer or Seller of notice that it bears responsibility for any matter under this Section 10, or with respect to any matter for which either party affirmatively undertakes responsibility hereunder, and assuming that the indemnifying party provides the indemnified party with evidence reasonably acceptable to the indemnified party that the indemnifying party will have the financial resources to defend against the Claim and fulfill its indemnification obligations hereunder, such party (the "Responsible Party") shall have the authority, at its option, to undertake control over all aspects and settlements of such matter, including without limitation, negotiations and settlements with interested government agencies and third parties. The Responsible Party shall keep the other party apprised of major developments relating to such matter and shall, subject to applicable legal privileges, make all reports, filings, and other documents relating to such matter available for inspection by the other party upon request. So long as the Responsible Party is managing the defense of the Claim in accordance with this Section
10(f)(ii), the indemnified party may retain separate co-counsel or other representatives at its sole cost and expense and participate in the management of the Claim. The parties agree to reasonably cooperate with one another in connection with any matter addressed hereunder, including without limitation allowing one another reasonable access to relevant personnel, records, and facilities. In the course of addressing any such matter, the Responsible Party and its representatives shall make best efforts to prevent any unreasonable interference with day-to-day operations at the Real Property on and after the Closing. In the event the Responsible Party declines to undertake control over a Claim or does not have the authority to undertake such Claim in accordance with this Section
10(f)(ii),(a) the

I-32

indemnified party may manage the Claim in any manner it reasonably may deem appropriate, with consent from the Responsible Party, which consent will not be unreasonably withheld, (b) the indemnifying parties will reimburse the indemnified party as and when incurred for the costs of defending against or otherwise managing the Claim (including reasonable attorneys' fees and expenses), and (c) the indemnifying parties will remain responsible for any Losses the indemnified party may suffer resulting from, arising out of, relating to, in the nature of, or caused by the Claim to the fullest extent provided in this Section 10(f)(ii).

(g) Offset. In the event that Buyer shall be entitled to indemnification under Section 10(a), the amount of any Losses, at Seller's option, shall be reimbursed by, first, forgiving interest accrued to the date on which Buyer and Seller agree Buyer is entitled to indemnification or as of the date of determination of the amount to which Buyer is entitled pursuant to Section 30 (to the extent theretofor unpaid) plus future interest payments when and as the same become due under the Buyer Note and, second, by forgiving principal payments on the Buyer Note as the same become due, in each case in an amount equal to the total amount of such Losses.

11. Assignment.

This Agreement shall be binding upon the respective parties and their respective successors and assigns; provided, however, this Agreement and any rights and obligations hereunder shall not be assignable or transferable by Buyer (including by operation of law in connection with a merger or sale of stock, or sale of substantially all the assets, of Buyer) without the prior written consent of Seller and any purported assignment without such consent shall be void and without effect.

12. No Third-Party Beneficiaries.

This Agreement is for the sole benefit of the parties hereto, and their permitted assigns and nothing herein express or implied (including Sections
8(k), 8(l), 8(m), 8(n) and 10) shall give or be construed to give to any Person, other than the parties hereto, and such permitted assigns, any legal or equitable rights hereunder and, in the case of Section 8(o) only, the present or former officers or directors of Buyer, who are the intended beneficiaries of
Section 8(o).

(iii) by Buyer if (x) at any time after October 31, 1996 any of the conditions set forth in Section 3(a) shall have become incapable of fulfillment, and shall not have been waived by Buyer, (y) Buyer has delivered to Seller on or prior to September 15, 1996 a notice that it is terminating this Agreement because it is not completely satisfied in all respects with its business, legal, environmental and accounting due diligence review and investigating of the Plastics Business or (z) Seller shall not have delivered to Buyer by September 30, 1996 copies of the Seller Resolutions that are in form and substance reasonably satisfactory to Buyer;

(iv) by Seller or Buyer if the Closing does not occur on or prior to December 31, 1996; provided, however, that the party seeking termination pursuant to clause (ii) or (iii) above (other than clause (ii)(y) or

(iii) Section 5(a) relating to indemnification in connection with the matters contemplated thereby, (iv) Section 15 relating to certain expenses, (v) Section 22 relating to finder's fees and broker's fees and (vi) this Section 13. Nothing in this Section 13 shall be deemed to release any party from any liability for any breach by such party of the terms and provisions of this Agreement or to impair the right of any party to compel specific performance by another party of its obligations under this Agreement.

14. Survival of Representations.

The representations and warranties in this Agreement and in any Schedules delivered in connection herewith shall expire at, and not survive, the Closing.

ART WORK

November 8, 1996

The Board of Directors
RYMAC Mortgage Investment Corporation
Penn Center West
Building 2, Suite 311
Pittsburgh, Pennsylvania 15276

Gentlemen:

We understand that RYMAC Mortgage Investment Corporation ("RYMAC") and Navistar International Transportation Corp. ("Navistar") have entered into an Asset Purchase Agreement, dated as of September 12, 1996, and as amended as of October 31, 1996 (the "Agreement"), pursuant to which Navistar will sell and RYMAC will purchase all of the assets relating exclusively to the business currently conducted at Navistar's Columbus Plastics Operation ("CPO"), primarily relating to the manufacture, marketing and sale of fiberglass and plastic component parts, as described in the Agreement (such sale and purchase being the "Transaction"). For purposes of this opinion, where appropriate, "RYMAC" includes RYMAC Mortgage Investment Corporation after giving effect to the Transaction.

The consideration that RYMAC will pay to Navistar in the Transaction will be calculated in accordance with Sections 1(f) and 1(g) of the Agreement. You have asked us to render our opinion as to whether such consideration is fair, from a financial point of view, to the stockholders of RYMAC. For purposes of this opinion, we have with your approval assumed that such consideration will consist solely of (a) a secured promissory note of RYMAC (the "Note") in an aggregate principal amount equal to the sum of (i) $25,504,000, plus or minus (ii) the difference between CPO's Net Tangible Assets (as defined in the Agreement) as of January 31, 1996 and CPO's Net Tangible Assets as of the closing date of the Transaction, calculated in accordance with Section 1(g)(i) of the Agreement, (b) 4,264,000 shares of the common stock, par value $.01 per share (the "Common Stock"), of RYMAC, and (c) certain contingent payments during each of the three fiscal years following the closing date of the Transaction, calculated in accordance with Section 1(g)(vi) of the Agreement and based on the excess, if any, between RYMAC's actual earnings before interest and taxes for each period over its projected earnings before interest and taxes for each period (collectively, the consideration described in clauses (a), (b) and (c) being the "Purchase Price"). You have provided us with a copy of the final Agreement and the registration statement on Form S-4 of Core Materials Corporation with respect to the transactions contemplated by the Agreement as filed with, and declared effective by, the Securities and Exchange Commission on the date hereof (the "Registration Statement").

The Board of Directors
RYMAC Mortgage Investment Corporation

In arriving at our opinion we have:

1. reviewed the Agreement and the Registration Statement;

2. reviewed certain historical financial statements of RYMAC and CPO provided, respectively, by the managements of RYMAC and Navistar, and reviewed certain additional operating and financial information relating to the past and current operations and financial condition, as well as the future prospects, of CPO provided to us by the management of RYMAC;

3. met with certain members of the management of RYMAC to discuss certain historical financial statements and projected financial information of RYMAC;

4. met with certain members of the management of Navistar to discuss certain historical financial statements and projected financial information, and certain additional operating and financial information relating to the past and current operations and financial condition, as well as the future prospects, of CPO;

5. reviewed certain pro forma combined projected financial information for RYMAC, after giving effect to the Transaction, prepared by the management of RYMAC, and met with certain members of the management of RYMAC to discuss such projected financial information;

6. reviewed the historical prices and trading volumes of the Common Stock;

7. reviewed certain publicly available financial data and stock market data of companies which we deemed generally comparable to CPO;

8. reviewed the publicly available terms of certain recent acquisitions of companies and businesses which we deemed generally comparable to CPO; and

9. reviewed such other information and conducted such other studies, analyses, inquiries and investigations as we deemed appropriate.

In the course of our analysis, we have relied upon and assumed without independent verification the accuracy and completeness of all information that was publicly available and the operating, financial and other information provided to us by or on behalf of RYMAC or Navistar or otherwise reviewed by us, and that all such information is not misleading, and we have not assumed, and do not assume, any responsibility or liability therefor. With respect to the projected financial information provided to us, we have assumed that they have been reasonably prepared on bases reflecting best currently available estimates and judgments of RYMAC's and Navistar's management as to the expected future results of operations, financial condition, prospects and performance of RYMAC and CPO. We have further relied upon the assurances of RYMAC's and Navistar's management that they are unaware of any facts that would make the projected financial information or other information provided to us inaccurate, incomplete or misleading. With your concurrence, we have not performed or obtained any appraisals of the assets or liabilities of CPO. In arriving at our opinion, we have used such valuation methodologies as we have deemed necessary or relevant. Our opinion is necessarily based on economic, market and other conditions, and the information made available to us, as of the date hereof.

II-2


The Board of Directors
RYMAC Mortgage Investment Corporation

In addition to the assumptions and limitations described in the preceding two paragraphs, we call your attention to the fact that the manner in which the Purchase Price has been calculated in the second paragraph of this letter for purposes of our opinion does not give effect to Section 1(g)(iii) of the Agreement which could increase the amount of consideration to be paid.

We have acted as financial advisor to RYMAC in connection with the Transaction and have received, and will receive upon delivery of this letter, fees for our services. In addition, RYMAC has agreed to indemnify us and certain of our affiliates for liabilities arising out of our services in connection with the Transaction, including the rendering of our opinion. In the ordinary course of our business, we may actively trade in securities of RYMAC or Navistar for our own account and for the account of customers, and accordingly may at any time hold a long or short position in any such securities.

Based upon and subject to the foregoing, it is our opinion that the Purchase Price is fair, from a financial point of view, to the stockholders of RYMAC. Our opinion is limited solely to the Purchase Price calculated as provided in the second paragraph of this letter, and we express no opinion with respect to the consideration that may actually be paid by RYMAC in the Transaction pursuant to Section 1(g)(iii) of the Agreement. In addition, we have not been requested to opine as to, and our opinion does not in any manner address, RYMAC's business decision to proceed with or effect the Transaction.

This letter is provided solely for benefit of the Board of Directors of RYMAC and may not be used or relied upon by, or disclosed, referred to or communicated by you to, any third party for any purpose whatsoever, except with our prior written consent.

Sincerely,

NOMURA SECURITIES INTERNATIONAL, INC.

Notwithstanding anything to the contrary herein, it is expressly agreed that the outstanding principal amount of this Note may, from time to time, be increased pursuant to certain purchase price adjustments set forth in Section 1(g) of the Purchase Agreement (the "Purchase Price Adjustments").

1. PAYMENTS OF PRINCIPAL AND INTEREST.

(a) Principal Payment. The Company shall pay principal installments under this Note to the Noteholder as follows:

(i) Within ninety (90) days after the end of each fiscal year of the Company during the term hereof, the Company shall pay principal in an amount equal to the amount, if any, by which the total cash and Cash Equivalents of the Company, as shown on the Company's audited balance sheet and statement of financial condition as of the end of such fiscal year, prepared in accordance with GAAP, exceeds Three Million Dollars ($3,000,000.00); and

(ii) In the event the Company obtains, from time to time, any Refinancing Loan, the Company shall promptly upon obtaining such loan pay principal in an amount equal to the proceeds of such loan.

If not sooner paid, the Company shall pay the entire principal amount of this Note then outstanding to the Noteholder in full on November , 2006 (the "Maturity Date"), together with any and all accrued and unpaid interest and any other amounts due hereunder.

(b) Interest. Except as otherwise expressly provided herein, interest shall accrue at the rate of eight percent (8.0%) per annum, (computed on the basis of a 360-day year and the actual number of days elapsed in any year) on the unpaid principal amount of this Note outstanding from time to time from and including the date hereof until the date paid, or (if less) at the highest rate then permitted under applicable law. The Company shall pay to the Noteholder all accrued interest on the last business day of each May and November, beginning after the date hereof. Notwithstanding anything to the contrary contained herein, on the date any such scheduled interest payment becomes due the Company may elect to add such interest payment to the outstanding principal balance of the Note to be repaid with interest in accordance with the provisions of this Note; provided, that (i) the board of directors of the Company by resolution declares that the payment of such scheduled interest payment would be reasonably expected to significantly effect the Company's and any of its Subsidiaries' ability to fund current operations and (ii) the Noteholder shall have received written notice of such election at least thirty (30) days before the date of such scheduled interest payment, which notice shall be accompanied by a certified copy of the resolution of the board of directors of the Company referred to in clause (i) above and an amendment to this Note, in form and substance satisfactory to the Noteholder, duly executed by the Company and dated as of the date such scheduled interest payment becomes due, which amendment shall increase the principal amount of this Note by the amount of such scheduled interest payment. Payments received by the Noteholder from the Company on this Note shall be applied first to the payment of interest which is due and payable and only thereafter to the outstanding principal balance hereof.

III-1


Unless prohibited under applicable law, any accrued interest which is not paid on the date on which it is due and payable shall bear interest at the same rate at which interest is then accruing on the principal amount of this Note until such interest is paid.

2. PREPAYMENTS; SETOFF.

(a) Optional Prepayments.

In connection with any prepayment of principal pursuant to this paragraph 2(a), the Company shall also pay all accrued and unpaid interest on the principal amount of this Note being prepaid. Any prepayment of less than all of the outstanding principal amount of this Note pursuant to this paragraph shall be applied to the scheduled payments of the outstanding principal amount of this Note in the inverse order of maturity.

(b) Right of Setoff. In addition to all other rights and remedies available to Navistar hereunder or otherwise, Navistar shall have the right, after the occurrence and during the continuance of any Default or Event of Default, to setoff against and to apply to the accrued and unpaid interest and outstanding principal balance of the Note (in each case, to the extent then due and payable), any obligation owing by Navistar to the Company. Any such setoff shall be applied first to the payment of interest which is due and payable and only thereafter to the outstanding principal balance hereof.

WHEREAS, the respective Boards of Directors of RYMAC and Core Materials have determined that it is advisable and in the best interests of each of such corporations that RYMAC merge with and into Core Materials upon the terms and subject to the conditions set forth in this Agreement for the purpose of effecting the change of the state of incorporation of RYMAC from Maryland to Delaware;

WHEREAS, the respective Boards of Directors of RYMAC and Core Materials have, by resolutions duly adopted, approved this Agreement;

WHEREAS, RYMAC has approved this Agreement as the sole stockholder of Core Materials; and

WHEREAS, the Board of Directors of RYMAC has directed that this Agreement be submitted to a vote of its shareholders.

2. Governing Documents. The Certificate of Incorporation of Core Materials, as in effect immediately prior to the Effective Time, shall be the Certificate of Incorporation of the Surviving Corporation without change or amendment until thereafter amended in accordance with the provisions thereof and applicable laws, and the By-laws of Core Materials, as in effect immediately prior to the Effective Time, shall be the By-laws of the Surviving Corporation without change or amendment until thereafter amended in accordance with the provisions thereof, of the Certificate of Incorporation of the Surviving Corporation and applicable laws.

To the extent permitted by law, any claim existing or action or proceedings pending by or against either of the Constituent Corporations may be prosecuted as if the Merger had not taken place. All debts, liabilities and duties of the respective Constituent Corporations shall thenceforth attach to the Surviving Corporation and may be enforced against it to the same extent as if such debts, liabilities and duties had been incurred or contracted by it. All corporate acts, plans, policies, agreements, arrangements, approvals and authorizations of RYMAC, its shareholders, Board of Directors and committees thereof, officers and agents which were valid and effective immediately prior to the Effective Time, shall be taken for all purposes as the acts, plans, policies, agreements, arrangements, approvals and authorizations of the Surviving Corporation and shall be as effective and binding thereon as the same were with respect to RYMAC. The employees and agents of RYMAC shall become the employees and agents of the Surviving Corporation and continue to be entitled to the same rights and benefits which they enjoyed as employees and agents of RYMAC. The requirements of any plans or agreements of RYMAC involving the issuance or purchase by RYMAC of certain shares of its capital stock shall be satisfied by the issuance or purchase of a like number of shares of the Surviving Corporation.

4. Directors. The number of Directors at the Effective Time shall be increased to five and shall consist of the following persons:

Richard R. Conte
Malcolm M. Prine
Ralph O. Hellmond
Thomas M. Hough
Thomas E. Rigsby

5. Further Assurances. From time to time, as and when required by the Surviving Corporation or by its successors or assigns, there shall be executed and delivered on behalf of RYMAC such deeds and other instruments, and there shall be taken or caused to be taken by it all such further and other action, as shall be appropriate, advisable or necessary in order to vest, perfect or confirm, of record or otherwise, in the Surviving Corporation the title to and possession of all property, interests, assets, rights, privileges, immunities, powers, franchises and authority of RYMAC, and otherwise to carry out the purposes of this Agreement, and the officers and directors of the Surviving Corporation are fully authorized in the name and on behalf of RYMAC or otherwise, to take any and all such action and to execute and deliver any and all such deeds and other instruments.

6. Conversion of Shares. At the Effective Time, by virtue of the Merger and without any action on the part of the holder thereof:

(a) each share of Maryland Common Stock outstanding immediately prior to the Effective Time shall be converted into the right to received one fully paid and nonassessable share of Delaware Common Stock; and

(b) the 1,000 shares of Delaware Common Stock presently issued and outstanding in the name of RYMAC shall be cancelled and retired and resume the status of authorized and unissued shares of Delaware Common Stock, and no shares of Delaware Common Stock or other securities of Core Materials shall be issued in respect thereof.

7. Condition to Merger. The respective obligations of each party to effect the merger shall be subject to the fulfillment at or prior to the Effective Time of the following conditions:

(a) the Merger shall have received the requisite approval of the holders of Maryland Common Stock pursuant to the General Corporation Law of the State of Maryland;

IV-2


(b) no statute, rule, regulation, decree, order or injunction shall have been promulgated, enacted, entered or enforced by any United States federal or state government, governmental agency or authority or court which remains in effect and prohibits, restrains, enjoins or restricts the consummation of the Merger.

8. Stock Certificates. At and after the Effective Time, all of the outstanding certificates which, immediately prior to the Effective Time, represented shares of Maryland Common Stock shall be deemed for all purposes to evidence ownership of, and to represent, shares of Delaware Common Stock into which the shares of Maryland Common Stock, formerly represented by such certificates, have been converted as herein provided. The registered owner on the books and records of the Surviving Corporation or its transfer agents of any such outstanding stock certificate shall, until such certificate shall have been surrendered for transfer or otherwise accounted for to the Surviving Corporation or its transfer agents, have and be entitled to exercise any voting and other rights with respect to, and to have received any dividends and other distributions upon, the shares of Delaware Common Stock evidenced by such outstanding certificate as above provided.

9. Options. Each option to purchase shares of Maryland Common Stock granted under the 1995 Stock Option Plan (the "Plan") of RYMAC which is outstanding immediately prior to the Effective Time, shall, by virtue of the Merger and without any action on the part of the holder thereof, be converted into and become an option to purchase the same number of shares of Delaware Common Stock at the same option price per share, and upon the same terms and subject to the same conditions as set forth in the Plan, as in effect at the Effective Time. The same number of shares of Delaware Common Stock shall be reserved for purposes of said Plan as is equal to the number of shares of Maryland Common Stock so reserved as of the Effective Time. As of the Effective Time, Core Materials hereby assumes the Plan and all obligations of RYMAC under the Plan, including the outstanding options or awards or portions thereof granted pursuant to the Plan, and the shares subject to such Plan shall thereafter be the shares of Delaware Common Stock reserved for issuance thereunder.

10. Amendment.

11. Abandonments. At any time prior to the Effective Time, this Agreement may be terminated, and the Merger may be abandoned by the Board of Directors of RYMAC, notwithstanding approval of this Agreement by the stockholder of Core Materials or by the shareholders of RYMAC, or both, if, in the opinion of the Board of Directors of RYMAC, circumstances arise which, in the opinion of such Board of Directors, make the Merger for any reason inadvisable.

12. Counterparts. In order to facilitate the filing and recording of this Agreement, the same may be executed in two or more counterparts, each of which shall be deemed to be an original and the same agreement.

13. Non-Survival. The covenants and agreements in this Agreement shall not survive the Merger, except for those covenants which by their terms survive the Merger.

14. Interpretation. The headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement.

15. Miscellaneous. This Agreement (i) constitutes the entire agreement and supersedes all other prior agreements and understandings, both written and oral, between the parties, with respect to the subject matter hereof, (ii) is not intended to confer upon any other person any rights or remedies hereunder, (iii) shall not be assigned by operation of law or otherwise and (iv) shall be governed by the laws of the State of Delaware.

V-2

ARTICLE VII

RESTRICTION ON TRANSFER OF SHARES,
ACQUISITION RESTORATION AND REDEMPTION RIGHT

SECTION 1. Affidavits of Transferees. Whenever it is deemed by the Board of Directors to be prudent in protecting the tax status of the Corporation, the Board of Directors may require to be filed with the Corporation a statement or affidavit from each proposed transferee of shares of capital stock of the Corporation setting forth the number of shares already owned by the transferee and any related person(s) specified in the form prescribed by the Board of Directors for that purpose. All contracts for the sale or other transfer of shares of capital stock of the Corporation shall be subject to this provision.

SECTION 2. Affidavits of Stockholders. Prior to any transfer or transaction which would cause a stockholder to own directly or indirectly, shares in excess of the Limit (as such term is defined in Section 4 of this Article), and in any event upon demand of the Board of Directors, such stockholder shall file with the Corporation an affidavit setting forth the number of shares of capital stock of the Corporation owned directly and indirectly by the person filing the affidavit. For purposes of this Section 2, shares of capital stock not owned directly shall be deemed to be owned indirectly by a person if that person would be the beneficial owner of such shares for purposes of Rule 13d-3, or any successor rule thereto, promulgated under the Securities Exchange Act of 1934, as amended or any successor statute thereto (the "Exchange Act"), and/or would be considered to own such shares by reason of the attribution rules in Section 544 of the Internal Revenue Code of 1986, as amended (the "Code") or the regulations issued thereunder. The affidavit to be filed with the Corporation shall set forth all information required to be reported in returns filed by stockholders under Treasury Regulation sec. 1.857-9 issued under the Code or similar provisions of any successor regulation, and in reports to be filed under Section 13(d); or any successor rule thereto, of the Exchange Act. The affidavit, or an amendment thereto, shall be filed with the Corporation within ten (10) days after demand therefor and at least fifteen (15) days prior to any transfer or transaction which, if consummated, would cause the filing person to hold a number of shares of capital stock of the Corporation in excess of the Limit. The Board of Directors shall have the right, but shall not be required, to refuse to transfer any shares of capital stock of the Corporation purportedly transferred other than in compliance with the provisions of this Section 2 of this Article.

SECTION 3. Prohibited Transfers. (a) Any acquisition of shares of capital stock of the Corporation that could or would (i) result in the direct or indirect imposition of any penalty tax on the Corporation (including the imposition of any entity-level tax on one or more real estate mortgage investment conduits (REMICs) in which the Corporation has acquired or plans to acquire an interest), (ii) jeopardize the tax status of one or more REMICs in which the Corporation has acquired or plans to acquire an interest or (iii) result in the disqualification of the Corporation as a real estate investment trust under the Code (collectively, a "Prohibited Transfer") will be void ab initio to the fullest extent permitted by applicable law, and the intended transferee of any shares that are the subject of a Prohibited Transfer will be deemed never to have had an interest therein. If the foregoing provision is determined to be void or invalid by virtue of any legal decision, statute, rule or regulation, then the transferee of such shares shall be deemed, at the option of the Corporation, to have acted as agent on behalf of the Corporation in acquiring such shares and to hold such shares on behalf of the Corporation. In addition, any shares of the Corporation that are the subject of a proposed, attempted or actual Prohibited Transfer may be redeemed by the Corporation at the discretion of the Board of Directors. Any such redemption will be effected as provided in Section 6 of this Article.

(b) Whenever it is deemed by the Board of Directors to be prudent in order to avoid a Prohibited Transfer, the Board of Directors may require a holder or proposed transferee of shares to file a statement or affidavit with the Corporation stating that the holder or proposed transferee is not a Disqualified Organization (as defined below); and any contract for the sale or other transfer of shares of the Corporation will be subject to this provision. For purposes of this article, a "Disqualified Organization" means the United States, any state or political subdivision thereof, any foreign government, any international organization or instrumentality of the foregoing, any tax-exempt entity other than a farmer's cooperative not subject to the unrelated business income tax, and any rural electric or telephone cooperative. The Board of Directors may, in its discretion,

V-3

refuse to transfer shares on the books of the Corporation if either (i) a statement or affidavit described above in this section has not been received or
(ii) the proposed transferee is a Disqualified Organization.

SECTION 4. Excess Shares. Notwithstanding any other provision hereof to the contrary and subject to the provisions of Section 5 of this Article, no person or persons acting as a group shall at any time directly or indirectly own in the aggregate more than 9.8% of the outstanding shares of capital stock of the Corporation (the "Limit"). Shares which but for this Article would be owned by a person or persons acting as a group and would, at any time, be in excess of the Limit are hereinafter referred to as "Excess Shares." For the purpose of determining ownership of Excess Shares, "ownership" of shares shall be deemed to include shares (i) constructively owned by a person under the provisions of
Section 544 of the Code and (ii) beneficially owned under the provisions of Rule 13d-3, or any successor rule, under the Exchange Act. For purposes of determining whether persons are acting as a group in connection with this Article, the term "group" shall have the same meaning as such term has for purposes of Section 13(d)(3) of the Exchange Act. All shares of capital stock of the Corporation which any person or persons acting as a group have the right to acquire upon exercise of outstanding rights, options and warrants, and upon conversion of any securities convertible into these shares, if any, shall be considered outstanding for purposes of determining whether such person or persons holds or hold shares in excess of the Limit if such inclusion will cause such person or persons to own shares in excess of the Limit. The Board of Directors shall have the right, but shall not be required, to refuse to transfer shares of capital stock on the books of the Corporation if, as a result of the proposed transfer, any person or persons acting as a group would hold or be deemed to hold Excess Shares.

SECTION 5. Exemptions. The Limit set forth in Section 4 of this Article shall not apply to the acquisition of shares of capital stock of the Corporation by an underwriter in a public offering of such shares or in any transaction involving the issuance of shares of capital stock by the Corporation in which the Board of Directors of the Corporation determines that the underwriter or other person or party initially acquiring such shares will timely distribute such shares to or among others so that, following such distribution, none of such shares will be deemed to be Excess Shares. The Board of Directors in its discretion may exempt from the Limit and from the filing requirements of Section 2 of this Article ownership or transfers of certain designated shares of capital stock of the Corporation while owned by or transferred to a person who has provided the Board of Directors with evidence and assurances acceptable to the Board of Directors that the qualification of the Corporation as a real estate investment trust under the Code and the regulations issued under the Code would not be jeopardized thereby.

SECTION 6. Redemption of Shares. At the discretion of the Board of Directors, all Excess Shares or shares that are the subject of a proposed, attempted or actual Prohibited Transfer (collectively, "Redemption Shares"), may be redeemed by the Corporation. Written notice of redemption shall be provided to all holders of Redemption Shares to be so redeemed not less than one week prior to the date on which such shares are to be redeemed (the "Redemption Date"), as determined by the Board of Directors and included in the notices of redemption. The redemption price to be paid for Redemption Shares shall be the fair market value of such Redemption Shares, which shall be (a) the closing price on the last business day prior to the Redemption Date of those shares on any national securities exchange on which the shares are listed or admitted to trading, (b) if the shares are not so listed or admitted to trading, the closing bid price on the last business day prior to the Redemption Date as reported on the National Association of Securities Dealers, Inc. Automated Quotation System, if quoted thereon, or (c) if the redemption price is not determinable in accordance with either clause (a) or (b) of this sentence, the net asset value of the shares (the proportionate interest of the shares to be redeemed in the total market value of all the assets of the Corporation less the total liabilities of the Corporation), determined in good faith by the Board of Directors. The redemption price for any shares of capital stock of the Corporation so redeemed shall be paid on the Redemption Date. From and after the Redemption Date, the holder of any shares of capital stock of the Corporation called for redemption shall cease to be entitled to any distributions and other benefits with respect to those shares, except the right to payment of the redemption price fixed as aforesaid.

SECTION 7. Application of Article. Nothing contained in this Article or in any other provision hereof shall limit the authority of the Board of Directors to take any and all other action as it in its sole discretion deems necessary or advisable to protect the Corporation and the interests of its stockholders by maintaining

V-4

the Corporation's eligibility to be, and preserving the Corporation's status as, a qualified real estate investment trust under the Code.

SECTION 8. Definition of "Person". For purposes of this Article only, the term "person" shall mean any individual, corporation, partnership, joint venture, association, joint stock company, trust (including any beneficiary thereof), unincorporated organization or government or any agency or political subdivision thereof.

SECTION 9. Severability. If any provision of this Article or any application of any such provision is determined to be invalid by any federal or state court having jurisdiction, the validity of the remaining provisions shall not be affected and other applications of such provision shall be affected only to the extent necessary to comply with the determination of such court.

ARTICLE VIII

LIABILITY OF DIRECTORS AND OFFICERS: INDEMNIFICATION

(3) Effective Date Tier Entity. Any Person that, as of the Article VIII Effective Date or the date that shares of Common Stock are issued pursuant to the Asset Purchase Agreement (as defined in B.5 below) after giving effect to such issuance, was a First Tier Entity or a Higher Tier Entity, for so long as such person continues to have a Prohibited Ownership Percentage.

(4) Expiration Date. The last day of the fifteen-year period commencing on the Article VIII Effective Date.

An "ownership change" with respect to the Corporation, as that term is used in Section 382(g) of the Internal Revenue Code and Treasury Regulations Section 1.382-2T(a)(1), except that for purposes of determining whether 5-percent shareholders have increased their percentage interests by more than 50 percentage points, there shall be added to the increase in their percentage interests an amount equal to 2.5% of the total value of the Stock of the Corporation.

(10) Other Permitted Holders. Any Person, other than an Effective Date Tier Entity or a Permitted Transferee, which has a Prohibited Ownership Percentage permitted under Section 1, whether pursuant to a waiver under Paragraph D of Section 1 or otherwise.

VI-3


Treasury Regulations Section 1.382-2T(g)(1)(i) or (ii). For this purpose, whether a Person or Public Group would be a "5-percent shareholder" shall be determined (u) by substituting "4.5 percent" for "5 percent" each place it appears in such provisions, (v) without giving effect to the following provisions: Treasury Regulations Sections 1.382-2T(g)(2), 1.382-2T(g)(3), 1.382-2T(h)(2)(iii) and 1.382-2T(h)(6)(iii), (w) by treating every Person or Public Group which owns Stock, whether directly or by attribution, as directly owning such Stock notwithstanding any further attribution of such Stock to other Persons and notwithstanding Treasury Regulations Section 1.382-2T(h)(2)(i)(A), (x) by substituting the term "Person" in place of "individual" in Treasury Regulations Section 1.382-2T(g)(1)(i), (y) by taking into account ownership of Stock at any time during the "testing period" as defined in Treasury Regulations Section 1.382-2T(d)(1), and (z) by treating each day during the testing period as if it were a "testing date" as defined in Treasury Regulations Section 1.382-2T(a)(2)(i).

(14) Public Group. A "public group" with respect to the Corporation, as that term is used in Treasury Regulations Section 1.382-2T(f)(13), excluding any "direct public group" with respect to the Corporation, as that term is used in Treasury Regulations Section 1.382-2T(j)(2)(ii).

(15) Stock. All classes of stock of the Corporation, all options to acquire stock of the Corporation and all other interests that would be treated as stock in the Corporation pursuant to Treasury Regulations

As used in this Article VIII, the term "option" shall have the meaning set forth in Treasury Regulations Section 1.382-2T(h)(4).

(16) Tax Benefits. The net operating loss carryovers and capital loss carryovers to which the Corporation is entitled under the Internal Revenue Code, free of restrictions under Section 382 of the Internal Revenue Code.

(17) Testing Date Action. Any Transfer or acquisition of Stock or any other action (including the acquisition or issuance of an option to Transfer or acquire Stock), if the effect of such Transfer, acquisition or other action would be to cause a "testing date" with respect to the Corporation within the meaning of Treasury Regulations Section 1.382-2T(a)(2)(i), determined by treating every Person and Public Group which has a Prohibited Ownership percentage as a 5-percent shareholder as used in such Section.

(18) Transfer. Any means of conveyance of legal or beneficial ownership of Stock, whether such ownership is direct or indirect, voluntary or involuntary, including, without limitation, an indirect transfer of ownership through the transfer of any ownership interest of any entity that owns Stock.

(19) Transferee Undertaking. A duly executed written undertaking for the benefit of the Corporation by any transferee pursuant to which the transferee agrees that (i) it will not take any of the following actions without the prior consent of the Board of Directors (x) acquire any additional Stock, (y) Transfer any Stock in violation of Paragraph B of
Section 1, or (z) take or cause to be taken any Testing Date Action, (ii) upon request by the Corporation, it will furnish or cause to be furnished to the Corporation all certificates representing Stock held of record or beneficially, directly or indirectly, by it or by any Person controlling, controlled by or under common control with it for the purpose of placing a legend on such certificates to reflect the undertakings described in clause
(i) above, (iii) it acknowledges that stop transfer orders may be entered with the transfer agent (or agents) and the registrar (or registrars) of Stock against the transfer of Stock subject to the undertakings described in clause (i) above except in compliance with the requirements of such undertakings, and (iv) it will agree to such other actions and remedies as the Corporation may reasonably request in order to preserve the Tax Benefits.

VI-4


(20) Treasury Regulations. The regulations promulgated by the Secretary of the Treasury under the Internal Revenue Code. Any reference to a particular Treasury Regulation or Section or provision thereof shall be deemed to also refer to any successor Regulation or Section or provision having similar effect.

B. Transfer Restrictions.

Unless otherwise consented to or waived by the Board of Directors, the following Transfers and actions shall be prohibited:

(1) General. No Person shall Transfer any Stock to any other Person to the extent that such Transfer, if effected, (i) would cause the transferee or any person or Public Group to have a Prohibited Ownership Percentage, or
(ii) would increase the ownership percentage of any transferee or any Person or Public Group having a Prohibited Ownership Percentage.

(2) Additional Restrictions on Transfers Involving Effective Date Tier Entities. In addition to the restrictions under Subparagraph B(1), (i) no Effective Date Tier Entity or individual that owns a direct ownership interest in the Corporation of five percent or more shall Transfer any Stock, and no other Person shall Transfer any Stock to an Effective Date Tier Entity, if, in either case, after such Transfer, there would be a 47 Percentage Point Increase, and (ii) no Effective Date Tier Entity or individual that owns a direct ownership interest in the Corporation of five percent or more shall take any other action (including the acquisition or issuance of an option to Transfer or acquire Stock) if, after such action, there would be a 47 Percentage Point Increase.

(3) Additional Restrictions on Transfers Involving Other Permitted Holders. In addition to the restrictions under Subparagraph B(1), (i) no Other Permitted Holder shall Transfer any Stock, and no other Person shall Transfer any Stock to an Other Permitted Holder, if, in either case, such Transfer would constitute a Testing Date Action, and (ii) no Other Permitted Holder shall take any other action that would constitute a Testing Date Action.

(4) Additional Restrictions under Transferee Undertakings. In addition to the restrictions under Subparagraph B(1), (i) no Person who has delivered a Transferee Undertaking shall Transfer any Stock, and no Person shall Transfer any Stock to any Person who has delivered a Transferee Undertaking, if, in either case, such Transfer would result in a violation of such Transferee Undertaking, and (ii) no Person who has delivered a Transferee Undertaking shall take or cause to be taken any other action that would constitute a Testing Date Action.

(5) Exception. Notwithstanding anything herein to the contrary, the issuance of shares of Common Stock of the Corporation to Navistar International Transportation Corp. ("Navistar") or its designees pursuant to the terms of an Asset Purchase Agreement, dated September 12, 1996 (the "Asset Purchase Agreement"), between Navistar and RYMAC Mortgage Investment Corporation shall not be deemed to be a violation of the transfer restrictions set forth in this Paragraph B.

C. Permitted Transfers.

(1) General. Unless otherwise restricted under Paragraph B of Section 1 or under a Transferee Undertaking or other agreement, Transfers of Stock may be made without the consent of the Board of Directors.

(2) Transfers by Effective Date Tier Entities. Upon petition by any Effective Date Tier Entity or individual that owns a direct ownership interest in the Corporation of five percent or more, the Board of Directors shall consent to a proposed Transfer of Stock that complies with Subparagraph B(2) of Section 1 but would otherwise be prohibited pursuant to Subparagraph B(1) of Section 1 if it determines that (i) after giving effect to such Transfer, the percentage of Stock owned by all Persons and Public Groups with a Prohibited Ownership percentage will not have increased by more than 47 percentage points over the lowest percentage of Stock owned by such Persons and Public Groups at any time during the three-year period preceding the proposed date of such Transfer (such determination to be made in accordance with the provisions of Treasury Regulations Section 1.382-2T(c)) and (ii) the proposed transferee shall have delivered a Transferee Undertaking.

VI-5


(3) Transfers by Permitted Transferees. Upon petition by any Permitted Transferee, the Board of Directors shall consent to a proposed Transfer of Stock or Testing Date Action that would otherwise be prohibited pursuant to Subparagraph B(1) or B(4) of Section 1 or pursuant to any Transferee Undertaking if it determines that (i) after such proposed Transfer or Testing Date Action there would not be an Ownership Change and (ii) in the case of any such proposed Transfer that, if effected, would otherwise be prohibited under Subparagraph B(1) of Section 1, such Transfer would otherwise be permitted under Subparagraph C(2) if such Transfer were proposed to be made by an Effective Date Tier Entity.

(4) Certain Additional Transfers to Permitted Transferees. Upon petition by any Permitted Transferee, the Board of Directors shall consent to a proposed Transfer of additional Stock to such Permitted Transferee from a Person constituting an Effective Date Tier Entity or another Permitted Transferee if it determines that such proposed Transfer would otherwise be permitted under Subparagraph C(2) or C(3) of Section I, as the case may be.

(5) Transfers by Other Permitted Holders. Upon petition by any Other Permitted Holder, the Board of Directors shall consent to a proposed Transfer of Stock or Testing Date Action that would otherwise be prohibited pursuant to Subparagraph B(1), B(3) or B(4) of Section 1 or pursuant to any Transferee Undertaking if it determines that (i) after such proposed Transfer or Testing Date Action there would not be an Ownership Change and
(ii) in the case of any such proposed Transfer that, if effected, would otherwise be prohibited under Subparagraph (B)(1) of Section 1, such Transfer would not cause a 47 Percentage Point Increase and the proposed transferee shall have delivered a Transferee Undertaking.

D. Waivers. Notwithstanding anything herein to the contrary, the Board of Directors may waive any of the restrictions contained in Paragraph B of Section 1 of this Article VIII: (a) in the case of any issuance of Stock by the Corporation which would otherwise be prohibited under Subparagraph B(1) of
Section 1, if the transferee agrees to be bound to the restrictions applicable to Permitted Transferees; (b) in the event of a tender or exchange offer within the meaning of the Securities Exchange Act of 1934, as amended, to acquire Stock constituting more than fifty percent in value of the outstanding Common Stock of the Corporation, so long as such waiver shall apply to all Transfers pursuant to such tender or exchange offer; (c) in connection with any Transfers of Stock in connection with underwritten offerings of such Stock; (d) in connection with any investment in or acquisition of a business or any business combination involving the Corporation or any subsidiary of the Corporation; and (e) in any other instance in which the Board of Directors reasonably and in good faith determines that a waiver would be in the best interests of the Corporation.

SECTION 2. Attempted Transfer in Violation of Transfer Restrictions. Unless the consent or waiver of the Board of Directors is obtained as provided in Paragraph C or D of Section 1, and except as provided in Paragraph C of Section 2 below, any attempted Transfer of shares of Stock of the Corporation in excess of the shares that could be Transferred to the transferee without restriction under Paragraph B of Section 1 is not effective to transfer ownership of such excess shares (the "Prohibited Shares") to the purported acquiror thereof (the "Purported Acquiror"), and the Purported Acquiror shall not be entitled to any rights as a shareholder of the Corporation with respect to the Prohibited Shares, including, without limitation, the right to vote or to receive dividends with respect thereto. Nothing contained in this Article VIII shall preclude the settlement of any transaction involving Stock entered into through the facilities of any national securities exchange on which the shares of Stock of the Corporation are listed. The application of the provisions and remedies described in the first sentence of this Section 2 and in Paragraphs A, B and C of Section 2 below shall be deemed not to so preclude any such settlement. Paragraphs A, B and C below shall apply only in the case of violations of the restrictions contained in Subparagraph B(1) of Section 1.

A. Transfer of Certificates; Sale of Stock. Upon demand by the Corporation, the Purported Acquiror shall transfer any certificate or other evidence of purported ownership of the Prohibited Shares within the Purported Acquiror's possession or control, together with any dividends or other distributions paid by the Corporation with respect to the Prohibited Shares that were received by the Purported Acquiror (the "Prohibited Distributions"), to an agent to be designated by the Corporation (the "Agent"). If the Purported Acquiror has sold the Prohibited Shares to an unrelated party in an arms-length transaction after purportedly acquiring them, the Purported Acquiror shall be deemed to have sold the Prohibited Shares for the Agent, and

VI-6


in lieu of transferring the Prohibited Shares and Prohibited Distributions to the Agent shall transfer to the Agent the Prohibited Distributions and the proceeds of such sale (the "Resale Proceeds") except to the extent that the Agent grants written permission to the Purported Acquiror to retain a portion of the Resale Proceeds not exceeding the amount that would have been payable by the Agent to the Purported Acquiror pursuant to Paragraph B of Section 2 if the Prohibited Shares had been sold by the Agent rather than by the Purported Acquiror. Any purported Transfer of the Prohibited Shares by the Purported Acquiror, other than a transfer described in one of the two preceding sentences (unless such transfer itself violated the provisions of Article VIII), shall not be effective to transfer any ownership of the Prohibited Shares.

B. Allocation and Distribution of Proceeds. The Agent shall sell in an arms-length transaction (through the American Stock Exchange, if possible) any Prohibited Shares transferred to the Agent by the Purported Acquiror, and the proceeds of such sale (the "Sales Proceeds"), or the Resale Proceeds, if applicable, shall be allocated to the Purported Acquiror up to the following amount: (1) where applicable, the purported purchase price paid or value of consideration surrendered by the Purported Acquiror for the Prohibited Shares and (2) where the purported Transfer of the Prohibited Shares to the Purported Acquiror was by gift, inheritance, or any similar purported transfer, the fair market value of the Prohibited Shares at the time of such purported Transfer. Any Resale Proceeds or Sales Proceeds in excess of the amount allocable to the Purported Acquiror pursuant to the preceding sentence, together with any Prohibited Distributions (such excess amount and Prohibited Distributions are collectively the "Subject Amounts"), shall be transferred to an entity designated by the Corporation that is described in Section 501(c)(3) of the Internal Revenue Code (the "Designated Charity"). In no event shall any such Prohibited Shares or Subject Amounts inure to the benefit of the Corporation or the Agent, but such Subject Amounts may be used to cover expenses incurred by the Agent in performing its duties.

C. Limitation on Enforceability. Notwithstanding anything herein to the contrary, with respect to any Transfer of Stock which would cause a Person or Public Group (the "Prohibited Party") to violate a restriction provided for in Subparagraph B(1) of Section I only on account of the attribution to the Prohibited Party of the ownership of Stock by a Person or Public Group which is not controlling, controlled by or under common control with the Prohibited Party, which ownership is nevertheless attributed to the Prohibited Party, Subparagraph B(1) of Section 1 shall not apply in a manner that would invalidate such Transfer. In such case, the Prohibited Party and any Persons controlling, controlled by or under common control with the Prohibited Party (collectively, the "Prohibited Party Group") shall automatically be deemed to have disposed of, and shall be required to dispose of, sufficient shares of Stock (which shares shall consist only of shares held legally or beneficially, whether directly or indirectly, by any member of the Prohibited Party Group, but not shares held through another Person, other than shares held through a Person acting as agent or fiduciary for any member of the Prohibited Party Group, and which shares shall be disposed of in the inverse order in which they were acquired by members of the Prohibited Party Group) to cause the Prohibited Party, following such disposition, not to be in violation of Subparagraph B(1) of Section 1; provided that in the event no member of the Prohibited Party Group (i) is an Effective Date Tier Entity, Permitted Transferee or Other Permitted Holder and (ii) had any actual knowledge that such Transfer was prohibited under Subparagraph B(1) of Section 1, such disposition shall only be effected to the extent necessary in order to prevent an Ownership Change. Such disposition shall be deemed to occur simultaneously with the Transfer giving rise to the application of this provision, and such number of shares which are deemed to be disposed of shall be considered Prohibited Shares and shall be disposed of through the Agent as provided in Paragraph B of Section 2, except that the maximum amount payable to the Prohibited Party in connection with such sale shall be the fair market value of the prohibited Shares at the time of the Prohibited Transfer.

D. Other Remedies. In the event that the Board of Directors determines that a Person proposes to take any action in violation of Paragraph B of Section 1, or in the event that the Board of Directors determines after the fact that an action has been taken in violation of Paragraph B of Section 1, the Board of Directors, subject to the second and third sentences of the introductory paragraph of Section 2, may take such action as it deems advisable to prevent or to refuse to give effect to any Transfer or other action which would result, or has resulted, in such violation, including, but not limited to, refusing to give effect to such Transfer or other action on the books of the Corporation or instituting proceedings to enjoin such Transfer or other action. If any Person shall knowingly violate Paragraph B of Section 1, then that Person and all other Persons controlling,

VI-7


controlled by or under common control with such Person shall be jointly and severally liable for, and shall pay to the Corporation, such amount as will, after taking account of all taxes imposed with respect to the receipt or accrual of such amount and all costs incurred by the Corporation as a result of such loss, put the Corporation in the same financial position as it would have been in had such violation not occurred.

SECTION 3. Prompt Enforcement Against Purported Acquiror. Within 30 business days of learning of a purported Transfer of Prohibited Shares to a Purported Acquiror or a Transfer of Stock to a Prohibited Party, the Corporation through its Secretary or any Assistant Secretary shall demand that the Purported Acquiror or Prohibited Party surrender to the Agent the certificates representing the Prohibited Shares, or any Resale Proceeds, and any Prohibited Distributions, and if such surrender is not made by the Purported Acquiror or Prohibited Party within 30 business days from the date of such demand, the Corporation shall institute legal proceedings to compel such surrender; provided, however, that nothing in this Section 3 shall preclude the Corporation in its discretion from immediately bringing legal proceedings without a prior demand, and also provided that failure of the Corporation to act within the time periods set out in this Section 3 shall not constitute a waiver of any right of the Corporation to compel any transfer required by Section 2. Upon a determination by the Board of Directors that there has been or is threatened a purported Transfer of Prohibited Shares to a Purported Acquiror or a Transfer of Stock to a Prohibited Party or any other violation of Paragraph B of Section 1, the Board of Directors may authorize such additional action as it deems advisable to give effect to the provisions of this Article VIII, including, without limitation, refusing to give effect on the books of the Corporation to any such purported Transfer or instituting proceedings to enjoin any such purported Transfer.

SECTION 4. Obligation to Provide Information. The Corporation may require as a condition to the registration of the Transfer of any Stock that the proposed transferee furnish to the Corporation all information reasonably requested by the Corporation with respect to all the direct or indirect ownership of Stock by the proposed transferee and by Persons controlling, controlled by or under common control with the proposed transferee.

SECTION 5. Legends. All certificates evidencing Stock that is subject to the restrictions on transfer set forth in this Article VIII shall bear a conspicuous legend referencing such restrictions.

SECTION 6. Further Actions. Subject to the second and third sentences of the introductory paragraph of Section 2, nothing contained in this Article VIII shall limit the authority of the Board of Directors to take such other action to the extent permitted by law as it deems necessary or advisable to protect the Corporation and the interests of the holders of its securities in preserving the Tax Benefits. Without limiting the generality of the foregoing, in the event of a change in law (including applicable regulations) making one or more of the following actions necessary, in the case of actions described in clauses (B),
(C) and (D) below, or desirable, in the case of actions described in clause (A) below, the Board of Directors may (A) accelerate the Expiration Date, (B) extend the Expiration Date, (C) conform any terms or numbers set forth in the transfer restrictions in Section 1 to make such terms consistent with the Internal Revenue Code and the Treasury Regulations following any changes therein to the extent necessary to preserve the Tax Benefits, or (D) conform the definitions of any terms set forth in this Article VIII to the definitions in effect following such change in law; provided that the Board of Directors shall determine in writing that such acceleration, extension, change or modification is reasonably necessary to preserve the Tax Benefits or that the continuation of these restrictions is no longer reasonably necessary for the preservation of the Tax Benefits, which determination shall be based upon an opinion of legal counsel to the Corporation and which determination shall be filed with the Secretary of the Corporation and mailed by the Secretary to all stockholders of the Corporation within ten days after the date of any such determination.

SECTION 7. Severability. If any provision of this Article VIII or the application of any such provision to any Person or under any circumstance shall be held invalid, illegal, or unenforceable in any respect by a court of competent jurisdiction, such invalidity, illegality or unenforceability shall not affect any other provision of this Article VIII.

VI-8

PART I

ITEM 1. BUSINESS

(A) GENERAL DEVELOPMENT OF BUSINESS.

RYMAC Mortgage Investment Corporation (the "Company") was incorporated in the State of Maryland on July 1, 1988. Prior to 1994, the Company was primarily engaged in making investments in mortgage derivative securities and, to a lesser extent, mortgage related investments, all of which are secured by single-family residential mortgage loans. Two wholly-owned, limited purpose finance subsidiaries of the Company, RYMAC Mortgage Investment I, Inc. ("RMI I") and RYMAC Mortgage Investment II, Inc. ("RMI II"), hold certain mortgage related investments. The Company also generates revenues from other sources, such as interest earnings on certain investments of the Company and sales of certain investments of the Company.

The Company has elected to be taxed as a real estate investment trust ("REIT") under the Internal Revenue Code of 1986, as amended (the "Code"). As long as the Company qualifies as a REIT, dividends paid to stockholders will be allowed as a deduction for purposes of determining income subject to federal corporate income tax. As a result, the Company will not be subject to such tax on that portion of its net income that is distributed to stockholders. (See "Federal Income Taxation of the Company and Stockholders")

(B) CURRENT BUSINESS ENVIRONMENT.

Since May 1992, the Company has not purchased any new mortgage derivative or mortgage related investments. During 1995, the Company purchased one 7% FNMA guaranteed pass-through certificate backed by 30 year single-family mortgage loans of which the Company maintains 100% ownership. The current principal balance is approximately $3.4 million. During the period from the Company's inception in 1988 through early 1992, mortgage interest rate levels and prepayment speeds remained within ranges existent from 1970 to early 1992. Historically, cash received from the Company's investment portfolio represented interest and dividend earnings and the return of investment principal (basis). However, from June of 1992 to early 1994, mortgage rates declined to levels lower than those existent for the prior twenty years, resulting in extraordinarily rapid and sustained levels of residential mortgage prepayments. As a direct result, the Company's investments generated sharply reduced interest and dividend earnings. Further, as the duration of high levels of prepayments continued, the Company's cash flows from returns of investment principal and interest and dividend earnings were also impaired and sufficient only to reduce the Company's borrowings (including margin calls), pay operating expenses and fund minimal dividend distributions to stockholders during the second half of 1992 and all of 1993, 1994 and 1995. As a result of these earnings difficulties and a substantially altered mortgage-backed securities market, the Company's Board of Directors elected in mid-1994 not to pursue its historical business. Instead, the Company and, since June 1995, its financial advisor have been investigating alternatives to the business currently conducted by the Company. Operating and capital losses incurred during 1992 through 1995 have resulted in tax losses estimated currently at $36 million. Such tax losses can be carried forward and utilized to offset future taxable income generated from current or contemplated activities before Company earnings are taxable or, as a REIT, result in dividend distributions.

Currently, the Company and its financial advisor are in the process of identifying and soliciting interest from suitable candidates regarding strategic transactions involving the acquisition of or merger with a profitable growing concern. The successful conclusion of a business combination or merger is subject to financial and economic conditions in the marketplace, the negotiation of mutually acceptable values, the particular requirements of the owners and management of other entities and the existence of competitive offers from entities with greater resources than those of the Company. To date, the Company has not successfully concluded any such discussions.

If the Company is unsuccessful in identifying a business combination or merger that is likely to produce value building results, it may elect to alternatively begin to develop an investment portfolio of financial assets. A decision to pursue such alternative investment activity would be subject to the Company's financial position as well as general economic and financial market conditions prevailing at such time. Either a new investment

VII-2


activity or any business combination or merger would seek to make effective use of the Company's tax loss position. (See "Management's Discussion and Analysis of Financial Condition and Results of Operations")

(C) NARRATIVE DESCRIPTION OF BUSINESS.

1. Management of Operations. The Company's investment policy is controlled by its Board of Directors (the "Board of Directors"). The By-laws of the Company provide that, except in the case of a vacancy, a majority of the members of the Board of Directors and of any committee of the Board of Directors must not be employed by, or otherwise affiliated with, the Company or its former manager.

2. Operating Policies and Strategies. Unprecedented high levels of mortgage refinancings resulting in prepayment of the Company's assets for all of 1992 and 1993 and continuing into the early part of 1994, have caused the Company to incur large operating losses. The extended duration of these prepayments permanently reduced cash flows and earnings from these same assets and caused the Company to consider alternative investment policies and strategies, including the purchase and financing of alternative financial assets and evaluation of potential business combinations. (See "Management's Discussion and Analysis of Financial Condition and Results of Operations--Investment Activities and Future Prospects for the Company")

During the four year period ended December 31, 1995, the Company incurred tax losses estimated at $36 million. Of this, it is estimated that $31 million represents operating losses while $5 million represents capital losses related to sales of assets. Operating tax losses may be carried forward for a period of up to 15 years from the date of occurrence, while capital tax losses can be carried forward for five years from occurrence. The Company's tax loss positions can be utilized to offset future taxable income before the Company's earnings again become taxable, or, as a REIT, result in required dividend distributions. Should its future activities be successful, the Company would be in a position to reinvest cash flows into suitable assets and activities.

Historically, the Company generated revenues primarily from investments in mortgage derivative securities ("Mortgage Derivative Securities"). The Company's investments in Mortgage Derivative Securities currently consist of (i) a class or classes of collateralized mortgage obligations ("CMOs") (as defined below) that either represents a regular class of bonds or a residual class of bonds or
(ii) interests in a class or classes of mortgage-backed pass-through certificates that either represent a regular class of certificates or a residual class of certificates. These securities entitle the Company to receive a portion of the cash flow from the Mortgage Collateral (as defined below) underlying the CMOs or mortgage-backed pass-through certificates. For federal income tax purposes, a majority of the Company's Mortgage Derivative Securities represent interests in real estate mortgage investment conduits ("REMICs"). A CMO is a security issued in one or more classes ("CMO Classes") collateralized by a specific group of mortgage loans or mortgage certificates guaranteed by GNMA, FNMA or FHLMC (collectively, the "Mortgage Certificates" and together with the mortgage loans, the "Mortgage Collateral") and evidences the right of the investors to cash flows from the assets underlying such CMO. The Company had also generated revenues from Mortgage Related Investments (as defined below) and had purchased for its portfolio shares of common stock of companies engaged in businesses similar to the Company's.

In addition, or as an alternative, the Company, with the approval of a majority of the Unaffiliated Directors, may adopt investment strategies which, among other things, could involve the acquisition of non-real estate related assets. Such strategies, if adopted, could result in the Company being unable to qualify as a REIT under the Code. The failure to qualify as a REIT could have severe adverse tax consequences for the Company. (See "Federal Income Taxation of the Company and Stockholders") However, the adverse tax consequences may be substantially mitigated by the Company's net operating losses.

The Company may elect to purchase or otherwise reacquire, shares of its Common Stock, par value $.01 per share ("Common Stock"), if, in the opinion of the Board of Directors, such purchases can be made upon favorable terms that can be expected to result in an increase in distributions or value to the remaining stockholders without adversely affecting the ability of the Company to maintain its qualification as a REIT under the Code. The Company did not purchase any shares of Common Stock during calendar 1995 nor does it anticipate any purchase of shares during calendar 1996.

VII-3


The Company previously utilized borrowings to purchase certain of the investments described above and contemplates the use of borrowings in regard to any new investment activity or business combination. During 1994, the Company elected to allow its bank line of credit to expire and repaid in full all outstanding repurchase agreements with Wall Street dealers. Since November 30, 1994, the Company has had no outstanding borrowings. (See "Capital Resources")

3. Types of Investments. Historically, the Company's portfolio of assets has included:

(a) Mortgage Related Investments. In its first fifteen months of operations, the Company's primary source of income was its mortgage related investments, wherein the Company purchased from issuers of CMOs the right to receive the cash flow of the CMO after debt service payments on the CMO are made ("Mortgage Related Investments").

(b) Mortgage Derivative Securities. Although Mortgage Related Investments still constitute a portion of the Company's portfolio, the Company's portfolio also includes other investments, consisting of Mortgage Derivative Securities such as IOs, Inverse IOs, PAC and TAC IOs, POs, IOettes, Floating Rate and Inverse Floating Rate Bonds, Z Bonds, MBSs, and Residual Bonds, as defined below.

1) An IO is an interest only class. An IO entitles the holder to receive the interest portion of the cashflow from the underlying mortgage-backed security. These securities are bearish in nature and thus show improved performance as prepayment speeds slow and interest rates rise.

2) An Inverse IO is created by dividing a fixed rate bond class into floating and inverse floating rate components based upon a market interest rate index, such that, at any time the sum of the interest payments to the two classes is no greater than the coupon on the fixed rate bond. As the index rises, more interest is required in the floating rate component and therefore less is available to the inverse floating rate holder. In a rising interest rate environment, the lower coupon payments due the Inverse IO holder are to some degree offset by the IO structure of the security. With rising rates, slower prepayments will enable the Inverse IO holder to recognize a decreased coupon on an outstanding balance for a longer period. An Inverse IO does not guarantee the par face of the bond, unlike an Inverse Floating Rate Bond (see 7 below), and is usually sold with nominal principal face amount but at a premium.

3) A PAC (Planned Amortization Class) IO is an IO with a fixed coupon calculated on a nominal principal balance that is protected within a band of prepayment rates. This prepayment band offers more average life assurance than a pure IO strip. A TAC (Targeted Amortization Class) IO is similar to a PAC IO except that the band of prepayment rates is much narrower. This narrower band makes the average life of a TAC IO more sensitive to prepayment speeds than a PAC IO.

4) A PO is a principal only class. A PO entitles the holder to receive the principal portion of the underlying mortgage-backed security. These securities are sold at a discount to face and benefit when interest rates fall and prepayment rates rise.

5) An IOette represents an interest only strip from a portion of the interest component of an underlying mortgage backed security. This security is bearish in nature as it shows improved performance as prepayments slow (interest rates rise).

6) A Floating Rate Bond is a CMO bond on which the interest rate paid to bondholders fluctuates with changes in an interest rate index, such as the London Interbank Offered Rate ("LIBOR"), and is usually reset monthly.

7) An Inverse Floating Rate Bond contains a coupon that fluctuates inversely with changes in a floating rate index such as LIBOR. As the index decreases, the formula used to set the coupon on this bond results in an increased yield. Typically, this type of Mortgage Derivative Security is purchased at or near the face amount of the bond. Although the face amount of principal will always be returned, it may be faster than expected due to an increase in prepayment speeds usually associated with lower interest rates.

8) A Z, or accrual, bond is a bond class that does not receive payments of interest until certain other classes of bonds are retired. Until the Z bond begins receiving interest payments, the amount of interest due is accrued, or added, to the principal amount of the bond.

VII-4


9) Residual Bonds, in general, entitle the holder to receive all or a portion of the residual cash flow from an underlying CMO after payment of principal and interest on all other bond classes and other expenses related to administration of the CMO.

(c) Mortgage-Backed Securities. An MBS, or Mortgage-Backed Security, is a security backed by an undivided interest in a pool of mortgage loans. The cash flow from the mortgage loans is used to pay principal of, and interest on, the securities. The most commonly recognized MBSs are issued through the following three governmental entities: GNMA; FNMA; and FHLMC.

4. Investment Portfolio. During the year ended December 31, 1995, in order to continue to qualify for an exemption under the Investment Company Act of 1940 (See "Investment Restrictions"), the Company made a sizeable investment in one 7% FNMA guaranteed 30 year single-family mortgage pool. (See "Current Business Environment" above, and "Management's Discussion and Analysis of Financial Condition and Results of Operations")

The information presented below and on the following pages, with respect to each of the Mortgage Derivative Securities, Mortgage Related Investments and Mortgage-Backed Securities held by the Company at December 31, 1995, was provided to the Company either by the issuer of the related CMO or obtained from the Bloomberg Financial System ("Bloomberg"). The Company did not participate in the issuance of such CMOs and is relying on the respective CMO Issuers and Bloomberg regarding the accuracy of the information provided. The Company believes, however, that such information is accurate. In reading the information presented below and on the following pages, only information regarding CMO classes whose structure and balance affect the performance of the Company's investment in the related Mortgage Derivative Security, Mortgage Related Investment or Mortgage-Backed Security is shown. For investments where no information is shown for other CMO classes, the performance of the Company's investment relates solely to prepayment speeds on the underlying Mortgage Collateral.

(1) Information on those RYMAC IV CMOs which did not have a payment date on January 1, 1996 is as of the payment date for such CMOs that preceded January 1, 1996. All other information is as of January 1, 1996.

5. Cash Flow from Investments. The Company's return on its investments has been substantially affected by a number of factors, including short-term interest rates to the extent that such rates affect certain of its investments, and the rates of prepayment of the underlying Mortgage Collateral. The rate at which principal payments occur on pools of single-family loans is influenced by a variety of economic, geographic, social and other factors. In general, however, mortgage loans are likely to be subject to higher prepayment rates if prevailing interest rates are significantly below the interest rates on the mortgage loans, as was the case during the time period of early 1992 to early 1994 and again during the second half of 1995. Conversely, in the event that interest rates are near or above the interest rate on the mortgage loans, the rate of prepayment would be expected to decrease as had been the case in the period of mid 1994 to mid 1995. The extended duration of unprecedented high levels of prepayments during the early 1992 to early 1994 time period caused permanent impairment to the cash flow levels of a majority of the Company's assets purchased prior to May of 1992. The extent of the impairment was such that a return to slower prepayment speeds did not materially improve the cash flow performance of such assets. Other factors affecting the rate of prepayment of mortgage loans include changes in mortgagor's housing needs, job transfers, unemployment, mortgagors' net equity in the mortgaged properties, assumability of mortgage loans, servicing decisions and the cost of refinancing.

The Company's Mortgage Derivative Securities each have different characteristics; thus the cash flows from any particular mortgage derivative security will vary based upon the structure of the particular Mortgage Derivative Security (see 3(b) above), the level of interest rates on mortgage loans and mortgage prepayment

VII-8


levels. However, the Company's portfolio of Mortgage Derivative Securities has been materially adversely affected because of such levels.

The Company's cash flow from its Mortgage Related Investments is derived from three principal sources: (a) any positive difference between the interest rates of the Mortgage Collateral and the weighted average interest rates of the related CMO Classes; (b) any amounts available from prepayments on the Mortgage Collateral that are not necessary for debt service payments on such CMOs; and
(c) any reinvestment income in excess of amounts required to ensure timely payments of principal and interest on such CMOs. The positive difference between rates on the Mortgage Collateral and the weighted average rates on the related CMO Classes was negatively affected by the rapid levels of mortgage prepayments in the 1992 to early 1994 period. Rapid prepayments result in 1) a reduction of the positive difference available to the Company and 2) a shortened duration of such positive difference. Also, lower interest rates result in reduced reinvestment rates.

Excess cash flow from a particular investment will decline over time and eventually terminate.

6. Other Potential Investments. The Company's Board of Directors adopted Investment Guidelines ("Guidelines") to provide general parameters for the Company's investments and borrowings pursuant to which the Company may make investments without case by case approval by the Board of Directors. The Guidelines list certain investments which the Company is permitted to make. Pursuant to the Guidelines, the Company may purchase Mortgage Collateral which the Company may hold or pledge to secure a CMO or to back other mortgage related securities. The Company may also acquire shares of equity securities of other CMO residual REITs. Additionally, the investment criteria set forth in the Guidelines, allow the Company, for a fee, to issue commitments to sellers of Mortgage Collateral. The Company may purchase mortgage loans (i) that are eligible for securitization and guaranty by GNMA, FNMA or FHLMC or (ii) that are not eligible for such securitization and guaranty. The Company may also purchase Mortgage Collateral that could subsequently be used to secure various CMOs issued by one or more CMO Issuers, and may participate in the issuance of CMOs by forming, acquiring or entering into arrangements with CMO Issuers. The Company has not engaged in any of such activities to date and does not expect to consider such activities. However, due to the performance of the Company's investment portfolio since 1992 and the altered business environment for mortgage investments in general, the Company has made only one substantial investment since May 1992 (See "Investment Portfolio" and "Management's Discussion and Analysis of Financial Condition and Results of Operations") and is currently required to seek specific Board of Directors approval for purchases of any new investment. The Board of Directors has authorized management 1) to continue evaluation of alternative investment activities and 2) to evaluate business combination proposals that could effectively utilize the Company's tax loss position.

7. Capital Resources. The Company had maintained a line of credit with a commercial bank for $250,000 which expired on April 30, 1994 and, at the Company's election, was not renewed. The line of credit had been used to fund day-to-day operating needs and in past periods to also temporarily fund acquisitions of new investments pending negotiation of repurchase agreements or awaiting return of invested principal.

The Company had historically supplemented its funds available for investment through repurchase agreements. The repurchase agreements entered into by the Company involved the transfer by the Company of certain of its assets to a financial institution in exchange for cash in an amount that was less than the fair market value of such assets. At the same time, the Company agreed to repurchase such assets at a future date at a price equal to the cash paid by such financial institution plus interest thereon. The extraordinarily high level of mortgage prepayments in the 1992 to mid 1994 period caused dealers to reduce substantially the financing value of investments pledged under repurchase agreements. Under such circumstances, the Company was required to reduce the amount of outstanding borrowings by cash payments under the repurchase agreement or the delivery of other unencumbered investments, thus reducing the Company's ability to purchase new investments. (See "Management's Discussion and Analysis--Liquidity and Capital Resources")

At December 31, 1995 and March 20, 1996 the Company had no outstanding borrowings under repurchase agreements. As such, all of the Company's Mortgage Derivative Securities and its Mortgage-Backed Security are available to secure future borrowings, although the financing value of such Mortgage Derivative Securities is substantially limited.

VII-9


The Company's By-laws provide that it may not incur additional indebtedness if, after giving effect to such indebtedness, its aggregate indebtedness (other than liabilities incurred in connection with participation in the issuance of CMOs and any loans between the Company and its corporate subsidiaries), secured and unsecured, would exceed 300% of the Company's average invested assets, in each case on a consolidated basis, as calculated at the end of each calendar quarter in accordance with generally accepted accounting principles, unless such additional indebtedness is approved by a majority of the Unaffiliated Directors. The Company is currently operating under a borrowing limitation pursuant to a policy adopted by its Board of Directors that limits total borrowings to $25,000,000, an amount substantially in excess of the amount the Company would be able to borrow under the current operating condition of the Company. At December 31, 1995 and March 20, 1996, the Company had no indebtedness outstanding. The Company's contemplated future activities could include borrowings by the Company which would be secured by a pledge of newly acquired assets and/or current portfolio assets.

The Company has authorized 50,000,000 shares of Common Stock. The Company's current financial condition substantially limits its ability to raise additional equity capital. The successful implementation of alternative investment strategies and/or the negotiation of a business combination may involve issuance by the Company of common stock. The Company believes that the issuance of equity securities in connection with alternative investment activities and/or a business combination and potentially raising additional equity capital based upon the success of such investment activity or combination is in the long-term best interests of the Company.

In addition, the Company's Articles of Incorporation permit the Board of Directors to authorize and issue from time to time additional classes of stock without the necessity of further approval by the stockholders and with such rights and preferences as the Board of Directors of the Company may designate by resolution. Depending upon the terms set by the Board of Directors, the authorization and issuance of preferred stock or other new classes of stock could adversely affect existing stockholders. The effects on stockholders could include, for example, dilution of existing stockholders, restriction on dividends on Common Stock, restrictions on dividends for other corporate purposes and preferences to holders of a new class of stock in the distribution of assets upon liquidation. Since the filing of the Articles of Incorporation, the Board of Directors has neither authorized nor issued any additional classes of stock.

8. Investment Restrictions. Restrictions on investments by the Company in certain types of assets are imposed by the provisions of the Investment Company Act of 1940, as amended (the "Investment Company Act"). The Investment Company Act specifically exempts entities primarily engaged in such activities from the definition of an investment company (the "Real Estate Exception"). Under interpretations issued by the staff of the Securities and Exchange Commission, in order to qualify for the Real Estate Exception, the Company must maintain at least 55% of its assets in mortgage loans or certain other interests in real estate, and another 25% of its assets in those or certain other types of real estate-related interests. The ability of the Company to acquire Mortgage Derivative Securities may be limited by the Investment Company Act depending, among other things, upon whether the Company acquires all or only a portion of the residual interest in a CMO, the nature of the collateral underlying such CMO and the composition of the balance of the Company's assets at the time of each such acquisition. Under interpretations of the staff of the Commission, investments in mortgage-backed or other mortgage related securities (including mortgage certificates) that are securities considered to be separate from the underlying mortgage loans are not considered to be investments in mortgage loans for purposes of the 55% test unless such securities represent all the certificates issued with respect to the underlying pool of mortgages. The Company's investment policies prohibit it from making any investments that would cause the Company to be an investment company within the meaning of the Investment Company Act. The Company monitors its operations in order to evaluate the qualification of the Company for the Real Estate Exception.

Uncertainties exist as to the interpretation of the exception from the definition of an investment company under the Investment Company Act for companies primarily engaged in the business of purchasing or otherwise acquiring mortgages and other liens on and interests in real estate. The Company believed that, based upon its historical method of operation, it fell within such exception. In connection with the review by the Commission of the registration statement for the Company's initial public offering, the Company had been advised, based on a preliminary review, that the staff of the Division of Investment Management of the

VII-10


Commission, while not taking a definitive position, was not in agreement with the Company's conclusion. If the Company were required to register as an investment company or to revise materially its contemplated method of operation to qualify for an exemption, it would be subject to additional limitations and restrictions on its activities.

In order to continue to qualify for an exemption under the Investment Company Act of 1940, (see note 2 of the Company's Consolidated Financial Statements), the Company made a sizeable investment in one 7% FNMA guaranteed 30 year single-family mortgage pool, of which the Company owns 100%, during the fourth quarter of 1995. Such security is AAA rated and was purchased at a price that under current market conditions minimizes principal risk to the Company.

If the Company were unable to qualify for the Real Estate Exception or otherwise engage in a business other than that of an investment company, it will be required to register as an investment company under the Investment Company Act. The Company is unable to predict how registration under such Act would affect its current plans to pursue new investment activities or business combinations. Registration under the Investment Company Act would also require the investments held by the Company to be adjusted to market value at the balance sheet date to the extent not done so already. The other financial statement reporting and disclosure requirements of the Investment Company Act may differ in certain respects from those to which the Company is currently subject.

The Company is prohibited from purchasing real estate contracts of sale. The Company also may not invest in unimproved real property or mortgage loans on unimproved real property, nor may it underwrite securities of other issuers. The foregoing restrictions may not be changed without the approval of a majority of the Unaffiliated Directors.

The Company may purchase or otherwise reacquire shares of its Common Stock if, in the opinion of the Board of Directors, the purchases can be made upon favorable terms that can be expected to result in an increase in distributions to the remaining stockholders. However, the Company may not make such purchases if to do so would adversely affect the ability of the Company to maintain its qualification as a REIT under the Code. (See "Federal Income Taxation of the Company and Stockholders")

The operating policies and strategies of the Company are governed by the Board of Directors, which has the power to modify or alter such policies without the consent of the stockholders.

9. Management Agreement and Fees. The Company's Management Agreement with its former manager expired on March 31, 1992. The Board of Directors determined that the Company would operate on a self-managed basis and, consequently, it did not enter into a new management agreement with its former manager.

On a self-managed basis, the Company is responsible for all expenses, including resources previously provided by the former manager.

10. Dividend Reinvestment Plan. On December 13, 1988, the Company adopted an Automatic Dividend Reinvestment Plan (the "Plan"). The Plan is administered by American Stock Transfer & Trust Company. The Plan provides to the Company's security holders a method of investing cash dividends paid by the Company in new shares of the Company's common stock. The Plan also permits participants to make optional cash investments in additional shares of the Company's common stock.

11. Federal Income Taxation of the Company and Stockholders. THE PROVISIONS
OF THE CODE ARE HIGHLY TECHNICAL AND COMPLEX. THIS SUMMARY IS NOT INTENDED AS A DETAILED DISCUSSION OF ALL APPLICABLE PROVISIONS OF THE CODE, THE RULES AND REGULATIONS PROMULGATED THEREUNDER, OR THE ADMINISTRATIVE AND JUDICIAL INTERPRETATIONS THEREOF. THE COMPANY HAS NOT OBTAINED A RULING FROM THE INTERNAL REVENUE SERVICE WITH RESPECT TO ANY TAX CONSIDERATIONS RELEVANT TO ITS ORGANIZATION OR OPERATION, OR TO AN INVESTMENT IN ITS SECURITIES. THIS SUMMARY IS NOT INTENDED TO SUBSTITUTE FOR PRUDENT TAX PLANNING, AND EACH STOCKHOLDER OF THE COMPANY IS URGED TO CONSULT ITS OWN TAX ADVISER WITH RESPECT TO THESE AND OTHER FEDERAL, STATE AND LOCAL

VII-11


TAX CONSEQUENCES OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF SHARES OF THE COMMON STOCK OF THE COMPANY AND ANY CHANGES IN APPLICABLE LAW.

GENERAL

The Company operates in a manner that permits it to qualify as a REIT under the Code. As a REIT, the Company itself generally will be subject to federal income tax only on the amount of its taxable income, subject to certain modifications ("REIT Taxable Income"), that it does not distribute in the taxable year in which it is earned. In addition, the Company will be subject to a 4% excise tax to the extent it fails to satisfy certain calendar year distribution requirements. The Company expects that, with limited exceptions, it will not be subject to federal income tax at the corporate level or to federal excise tax.

The Company would be subject to tax (including any applicable minimum tax) on its taxable income at regular corporate rates without any deduction for distributions to stockholders if it failed to qualify as a REIT in any taxable year. Unless entitled to relief under specific statutory provisions, the Company also would be disqualified from treatment as a REIT for the following four taxable years. The failure to qualify as a REIT for even one year could result in the Company incurring substantial indebtedness in order to pay any resulting taxes, thus reducing the amount of cash available for distribution to stockholders.

For purposes of the special REIT taxation rules and the REIT qualification requirements set forth below, the assets, liabilities, income and deductions of any subsidiary, all of whose stock has been owned by the Company during the subsidiary's entire existence ("Qualified REIT Subsidiary"), will be treated as assets, liabilities, income and deductions of the Company.

REIT QUALIFICATION REQUIREMENTS

In order to qualify as a REIT, the Company must satisfy various requirements with respect to (i) the nature of its assets ("Asset Requirements") and income ("Income Requirements"), (ii) certain organizational matters ("Organizational Requirements") and (iii) the amount of distributions to stockholders ("Distribution Requirements").

Under the Asset Requirements, at the close of each quarter during the taxable year (a) at least 75% of the assets of the Company, by value, must consist of specified real estate assets, cash or U. S. government securities and
(b) as to its other assets other than securities of a Qualified REIT Subsidiary, the Company cannot own (1) securities of any one issuer which represent more than 5% of the total value of the Company's assets or (2) more than 10% of the outstanding voting securities of any one issuer.

The Income Requirements provide that at least 75% of the Company's gross income must be derived from specified real estate related sources, including interest on mortgage obligations, income from REMIC interests, and gains from the sale of such obligations and interests not held primarily for sale to customers in the ordinary course of business ("Dealer Property"). Additionally, at least 95% of the Company's gross income must consist of income derived from items that qualify for the 75% income test plus other specified types of passive income, such as interest, dividends and gains from the sale or other disposition of stock and securities other than Dealer Property.

If the Company fails to satisfy either of the foregoing 75% and 95% Income Requirements but (a) the Company otherwise satisfies the requirements for qualification as a REIT, (b) such failure is due to reasonable cause and not willful neglect and (c) certain other requirements are met, then the Company will continue to qualify as a REIT but will be subject to a 100% tax on the greater of the amount by which it fails to satisfy either of such tests reduced by expenses incurred in earning that amount.

The Income Requirements also require that less than 30% of the Company's gross income be derived from the sale or other disposition of (a) stock or securities held for less than one year, (b) certain Dealer Property and (c) most real property (including mortgage obligations and REMIC interests) held for less than four years. In addition, the Code also generally imposes a 100% tax on gains (less associated expenses) derived from sales of Dealer Property (without an offset for any losses).

VII-12


The Distribution Requirements require that the Company distribute annually at least 95% of its REIT Taxable Income (and 95% of certain other income related to foreclosure property), excluding any net capital gain, to its stockholders. For this purpose, certain dividends paid by the Company after the close of a taxable year may be considered as having been paid during such taxable year, although they would be taxed to the stockholders in the year in which they were actually paid. Such dividends will also be treated as paid during the taxable year for purposes of determining whether the Company has undistributed REIT Taxable Income subject to income tax at the corporate level for the taxable year. For purposes of the 4% excise tax (described above), however, such dividends would not be treated as having been distributed in the taxable year. In addition, dividends declared in October, November or December of a calendar year, payable to stockholders of record as of a date in such a month, and actually paid during January of the following year will be considered as paid on December 31 of such calendar year for excise tax purposes as well as for other purposes under the REIT rules. Such dividends, however, will also be treated as having been paid on that December 31 for purposes of determining a stockholder's gross income.

Due to the nature of the Company's income from its assets and its deductions in respect of its obligations, under certain circumstances, the Company may generate REIT Taxable Income in excess of its cash flow. For example, the maturity and pass-through rates of the Mortgage Collateral pledged to secure the CMO issuances in which the Company holds an investment are not likely to match the maturity and interest rates of the CMOs secured thereby. Similarly, the Company may recognize taxable market discount income with respect to its receipts from the sale, retirement or other disposition of the portion of the Mortgage Collateral that constitutes market discount bonds (i.e., obligations with a stated redemption price at maturity greater than the Company's tax basis therein), whereas these receipts frequently will be used to make nondeductible principal payments on CMOs. In addition, certain CMOs may be issued with original issue discount, the tax treatment of which may result in taxable income in excess of cash flow. Accordingly, the Company may be required to distribute a portion of its working capital to its stockholders or borrow funds to make required distributions in years in which the gross income of the Company on a tax basis (including "non-cash" income) exceeds its deductible expenses. In the event that the Company is unable to pay dividends equal to substantially all of its REIT Taxable Income, it may incur income tax or excise tax or may not be able to qualify as a REIT.

Dividends paid for a fiscal year in excess of the Company's earnings and profits, as computed for federal income tax purposes, are reported as a return of capital to the Company's stockholders. Some of the Company's investments constitute REMIC residual interests. Certain of these residual interests produce "excess inclusion" income (see "Excess Inclusion Income" below) during the fiscal year. The Code requires that excess inclusion income be included in a taxpayer's income even though the taxpayer has losses that would otherwise offset such income. As a result, the Company could have taxable income from excess inclusions in a taxable year even though it has losses from other investments that would normally be sufficient to offset the amount of such excess inclusion income. The Company is required to distribute the taxable income representing excess inclusions to meet its 95% distribution requirement and to avoid a corporate level tax on such income. When such income is distributed to a stockholder, the stockholder will have taxable income, rather than a return of capital, equal to its share of such excess inclusion income during the fiscal year. For fiscal 1993, the Company reported that all its distributions paid in 1993, even though it experienced both a net loss and a tax loss for 1993, represented excess inclusion income. Although the Company made no distributions in 1994, excess inclusion income which was reported to the Company for 1994 was declared payable to stockholders in September 1995, prior to the Company's filing of its 1994 Tax Return. This distribution represented 1995 taxable income to stockholders. For a stockholder, excess inclusion income cannot be offset by losses, except in the case of certain excess inclusion income for certain savings and loan associations and their "qualified" subsidiaries.

The most significant Organizational Requirement is that the stock of the Company must be widely held. This requires that the stock of the Company be held by a minimum of 100 persons for at least 335 days in each taxable year and that no more than 50% in value of the stock be owned, actually or indirectly, by five or fewer individuals at any time during the second half of each taxable year. For this purpose, some pension funds and certain other tax-exempt entities are treated as individuals. To evidence compliance with these requirements, the Company is required to maintain records that disclose the actual ownership of its outstanding shares of

VII-13


Common Stock. In fulfilling its obligations to maintain records, the Company must demand written statements each year from the record holders of designated percentages of its shares of Common Stock which would, among other things, disclose the actual owners of such shares.

EXCESS INCLUSION INCOME

All of the cash dividends distributed to the Company's stockholders in 1993 were comprised of "excess inclusion" income. There were no distributions for 1994, but excess inclusion income reported to the Company for 1994 was declared payable to stockholders in September 1995, prior to the Company's filing of its 1994 Tax Return. Such distribution represents 1995 taxable income to stockholders. Excess inclusion income is attributable to CMO issuances for which an election has been made to be treated as a REMIC for federal income tax purposes. The portion of the Company's dividends determined to be excess inclusion income is taxable to certain otherwise tax-exempt stockholders as unrelated business income. In addition, generally, excess inclusion income may not be offset by any deductions or losses, including net operating losses.

12. Restrictions on Transfer and Redemption of Shares. Two of the requirements for qualification as a REIT under the Code are that (i) during the last half of each taxable year not more than 50% of the outstanding shares may be owned directly or indirectly by five or fewer individuals and (ii) there must be at least 100 stockholders for at least 335 days in each taxable year. Those requirements apply for all taxable years after the year in which the REIT elects REIT status.

In order that the Company may meet these requirements at all times, the Company's Articles of Incorporation prohibit any person or group of persons from acquiring or holding, directly or indirectly, ownership of a number of shares of Common Stock in excess of 9.8% of the outstanding shares. Shares of Common Stock owned by a person or group of persons in excess of such amounts are referred to in the Articles of Incorporation and herein as "Excess Shares." The Articles of Incorporation also provide that in the event any person acquires Excess Shares, such Excess Shares may be redeemed by the Company, at the discretion of the Board of Directors.

Under the Company's Articles of Incorporation, any acquisition of shares of the Company that would result in the disqualification of the Company as a REIT under the Code is void to the fullest extent permitted by law, and the Board of Directors is authorized to refuse to recognize a transfer of shares to a person if, as a result of the transfer, that person would own Excess Shares.

Additional provisions regarding restrictions on transfers and redemptions of the Company's shares are set forth in the Company's Articles of Incorporation, which were filed as Exhibit 3.1 to Amendment No. 1 to the Company's Registration Statement No. 33-22891 on Form S-11.

The Articles of Incorporation also contain provisions intended to minimize the potential adverse effect on the Company of a Code provision that would impose a tax on REITs (and other pass-through entities) that hold REMIC interests if at any time during the taxable year a Disqualified Organization (as defined below) is a record holder of an interest in such entity. A "Disqualified Organization" means the United States, any state or political subdivision thereof, any foreign government, any international organization or instrumentality of the foregoing, any tax-exempt entity, other than a farmer's cooperative, not subject to the unrelated business income tax and any rural electric or telephone cooperative. If a Disqualified Organization were a stockholder of record of the Company during a year in which the Company held a REMIC interest, a tax might be imposed on the Company. The amount of tax would be equal to the product of the highest marginal corporate tax rate and the amount of REMIC excess inclusions for the taxable year allocable to the interest in the Company held by the Disqualified Organization.

Accordingly, the Articles of Incorporation provide that any acquisition of shares of the Company that could or would result in the direct or indirect imposition of a penalty tax on the Company (including the tax described above) (a "Prohibited Transfer") will be void ab initio to the fullest extent permitted by applicable law, and the intended transferee of any shares that are the subject of a Prohibited Transfer may be deemed never to have had an interest therein. If the foregoing provision is determined to be void or invalid, the transferee shall be deemed, at the option of the Company, to have acted as agent of the Company in acquiring those shares and to hold those shares on behalf of the Company. In addition, any shares of the Company that

VII-14


are the subject of a proposed, attempted or actual Prohibited Transfer may be redeemed by the Company at the discretion of the Board of Directors. Any such redemption will be effected as provided in the preceding paragraphs with respect to Excess Shares. Furthermore, whenever it is deemed by the Board of Directors to be prudent in order to avoid a Prohibited Transfer, the Board of Directors may require a holder or proposed transferee of shares to file a statement or affidavit with the Company, stating that the holder or proposed transferee is not a Disqualified Organization; and any contract for the sale or other transfer of shares of the Company will be subject to this provision. Moreover, the Board of Directors may, in its discretion, refuse to transfer shares on the books of the Company if (i) a statement or affidavit described in the preceding sentence has not been received or (ii) the proposed transferee is a Disqualified Organization.

13. Competition. In purchasing Mortgage Derivative Securities, Mortgage Collateral, Mortgage-Backed Securities, all of which the Company currently owns, or other assets, including assets which the Company may utilize in future alternative investment activities, the Company competes, or will compete, with investment banking firms, savings and loan associations, banks, mortgage bankers, insurance companies and other lenders, other REITs, GNMA, FNMA and FHLMC and other entities, many of which have greater financial resources than the Company.

Additionally, as the Company and its financial advisor seek to identify suitable candidates regarding a strategic transaction involving the acquisition of or merger with a profitable growing concern, it competes with offers from entities with greater resources than those of the Company, such as financial buyers, venture capitalists, corporate entities and other investment groups.

As a REIT, the Company's business activities are limited by the provisions of the Code that require a REIT to meet certain tests to maintain its qualification as a REIT. Many of the Company's competitors operate through entities that may have more flexibility than the Company in conducting their business operations. In regard to its future activities, the Company may forfeit its REIT status, either voluntarily or involuntarily.

14. Employees. The Company employs two full-time employees and one part-time employee as of December 31, 1995, and utilizes the services of consultants, as necessary.

ITEM 2. PROPERTIES.

The Company does not own real estate or physical property. The executive offices of the Company are located in leased space at 100 North Fourth Street, Suite 813, P.O. Box 250, Steubenville, Ohio 43952. The lease covering such space can be terminated at any time with notice to the lessor.

ITEM 3. LEGAL PROCEEDINGS.

As of December 31, 1995, there were no legal proceedings pending or threatened to which the Company or its subsidiaries were a party or to which any of their respective property was subject.

ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.

No matters were submitted to a vote of the Company's security holders during the fourth quarter of 1995.

In order to qualify as a REIT under the Code, the Company, among other things, must distribute as dividends to its stockholders an amount at least equal to (i) 95% of its REIT Taxable Income (determined before the deduction for dividends paid and excluding any net capital gain and any net income from the sale or other disposition of property held primarily for sale) plus (ii) 95% of the excess of its net income from foreclosure property over the tax imposed on such income by the Code less (iii) any excess noncash income (as determined under the Code). The actual amount and timing of dividend payments, however, is at the discretion of the Board of Directors and depends upon the financial condition of the Company in addition to the requirements of the Code.

The Company's Common Stock was held by 466 stockholders of record on March 20, 1996.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS.

INVESTMENT ACTIVITIES AND FUTURE PROSPECTS FOR THE COMPANY

A portion of the Company's current portfolio of investments continues to be sensitive to changes in interest rates and mortgage prepayments. The lowest mortgage interest rate levels in 20 years were reached in 1992 and continued to 25 year lows during the fourth quarter of 1993, resulting in unprecedented mortgage refinancings and vastly accelerated mortgage prepayments. As a result of the high level and extended duration of these prepayments, earnings and cash flows from the Company's investments were adversely impacted. For a large majority of those assets, earnings and cash flows were permanently impaired and did not recover even as prepayments returned to more historical levels in the second, third and fourth quarters of 1994. These permanent impairments were the direct result of the massive level of paydowns on the mortgages collateralizing such investments. During this time frame, most of the Company's assets represented the ownership of identified cash flows in diverse CMO structures. Prepayments of the underlying mortgage collateral, especially of the magnitude and duration experienced from early 1992 through early 1994, served to permanently reduce cash flows even when prepayment speeds slowed. As an example, a specific identified cash flow representing a single class of a CMO collateralized by $100 million in mortgages produces only 20% of the original expected cash flows when the underlying mortgage collateral prepays unexpectedly to a $20 million level. This type of phenomenon was representative of the marketplace for investments of the type owned by the Company during 1992 to mid-1994.

In light of its earnings difficulties and the erratic conditions in the mortgage-backed securities markets, both caused by the 1992 to mid-1994 prepayment environment discussed above, the Company elected in mid-1994 not to pursue its historical business. With a slow down in prepayment speeds during the second half of 1994, the Company sold a substantial portion of its investment portfolio, using the proceeds from such sales to repay all its borrowing obligations and temporarily invest cash excesses in high quality liquid investments. The Company then began to explore the prospects for a business combination or merger with a profitable growing concern and simultaneously began investigating alternative investment activities outside the Company's historical business.

In regard to its search for an appropriate business combination or merger, the Company's Board of Directors established acquisition criteria in an effort to direct management's efforts and, in June of 1995, engaged a financial advisor to permit the Company to uncover and analyze a wider array of potential transactions.

VII-17


Currently, the Company and its financial advisor continue the process of identifying suitable candidates regarding a strategic transaction involving the acquisition of or merger with a profitable growing concern. The successful conclusion of a business combination or merger is subject to financial and economic conditions in the marketplace, the negotiation of mutually acceptable values, the particular requirements of the owners and management of other entities and the existence of competitive offers from entities with greater resources than those of the Company. To date, the Company has not successfully concluded any such negotiations.

Any such transaction may involve payment by the Company of a cash purchase price, the issuance of notes or preferred or common stock or some combination thereof. In any case, it is anticipated that the consummation of a transaction would be conditioned upon the receipt of stockholder approval at a special meeting called for such purpose.

If the Company is unsuccessful in identifying a transaction that is likely to produce value building results, it may elect to alternatively begin to develop an investment portfolio of financial assets as a means of increasing value to stockholders. A decision to pursue such alternative investment activity would be subject to the Company's financial position as well as general economic and financial market conditions prevailing at such time.

The Company and its financial advisor continue to believe that the future potential earnings and value building aspects of utilizing its assets in a successful business combination outweigh those of rebuilding an investment portfolio containing lower-risk assets than those previously composing the Company's investment portfolio.

In order to continue to qualify for an exemption under the Investment Company Act of 1940 (see note 2 of the Company's Consolidated Financial Statements), the Company made a sizeable investment in one 7% FNMA guaranteed 30 year single-family mortgage pool, of which the Company maintains 100% ownership, during the fourth quarter of 1995. Such security is AAA rated and was purchased at a price that under current market conditions minimizes principal risk to the Company.

DIVIDEND POLICY

In accordance with the Code, the Company is required to distribute at least 95% of its taxable income to its stockholders each year in order to maintain its status as a REIT. Dividends paid for a fiscal year in excess of the Company's taxable income are reported as a return of capital to the Company's stockholders, except as provided below.

Some of the Company's investments constitute REMIC residual interests. Certain of these residual interests may produce "excess inclusion" income during the fiscal year. The Code requires that excess inclusion income be included in a taxpayer's income even though the taxpayer has current or prior losses that would otherwise offset such income. As a result, the Company could have taxable income from excess inclusions in a taxable year even though it has current or prior losses from other investments that would normally be sufficient to offset the amount of such excess inclusion income. The Company is required to distribute the taxable income representing excess inclusions to meet its 95% distribution requirement and to avoid a corporate level tax on such income. When such income is distributed to a stockholder, the stockholder will have taxable income, rather than a return of capital, equal to its share of such excess inclusion income during the fiscal year. For a stockholder, generally, excess inclusion income cannot be offset by losses.

For the tax year ended December 31, 1995, the Company paid a dividend of $0.003 per share on September 29, 1995 to stockholders of record on September 20, 1995. This 1995 dividend was the result of excess inclusion income and is reportable by stockholders as taxable income for 1995.

RESULTS OF OPERATIONS

1995 TO 1994 COMPARISONS

STATEMENT OF REVENUES AND EXPENSES

Net Income/(loss), as calculated in accordance with generally accepted accounting principles, and as presented in the accompanying consolidated financial statements, for the twelve months ended December 31,

VII-18


1995, was $(756,000), or $(0.15) per share, as compared to $805,000, or $0.15 per share, for the twelve months ended December 31, 1994.

Generally accepted accounting principles require the Company to periodically evaluate its investments based upon current and expected future mortgage prepayment speeds and interest rates and, effective December 31, 1993, market discount rates, as well. (See note 2 to the Company's Consolidated Financial Statements) Downward valuation adjustments, if necessary, are reflected as a reduction of interest revenues in the Company's Consolidated Statements of Revenues and Expenses. The results for 1995 reflect downward valuation adjustments totaling $700,000, or $(0.13) per share, all incurred during the second quarter of 1995. For 1994, downward adjustments in carrying value were $285,000, or $(0.05) per share.

The reduction in the Company's Net Income/(loss) from 1994 to 1995 of $1,561,000 is due to 1) larger writedowns in value of Company investments during 1995 and 2) the existence of gains from the sale of assets in 1994, offset by reduced operating expenses for 1995. Downward asset valuation adjustments in 1994 were $285,000, while such writedowns in 1995 were $700,000, an increase of $415,000. In 1994, the Company recorded net gains on the sales of assets of $1,119,000. In 1995, the Company had no gains related to asset sales. Absent 1994 sales gains, the Company's Net Income would have been $(314,000), or $(0.06) per share. The Company further reduced operating expenses from $850,000 in 1994 to $590,000 in 1995, a decrease of $260,000.

The assumptions used to value assets at the end of each quarter take into consideration the current level of interest rates (short and long), actual mortgage prepayment speeds experienced for each asset through the end of the quarterly period, market expectations of future prepayment speeds for the mortgages backing each asset and, effective December 31, 1993, the application of a market discount rate to future cash flows. If prepayment speeds were to occur at levels higher than market expectations, market expectations of future mortgage prepayment speeds increase beyond current anticipated levels, short term interest rates increase beyond their current levels, or the market discount rate applied were to be increased, further reductions in the value of the Company's investments could be necessary.

Interest revenue on Mortgage Related Investments decreased from $2,208,000 for the year ended December 31, 1994 to $1,063,000 for the year ended December 31, 1995, as a result of the reduction in Mortgage Related Investments on the Company's Balance Sheet between December 31, 1994 and December 31, 1995, discussed below. Interest revenue on Mortgage Derivative Securities was $612,000 for the year ended December 31, 1994 as compared to $(447,000) for the year ended December 31, 1995. The decrease in interest revenue on Mortgage Derivative Securities of $1,059,000 was primarily attributable to a $700,000 writedown of this asset category for 1995 while such writedowns were only $285,000 for 1994. Such writedowns are deducted from Mortgage Derivative Securities interest revenues. There was also a general reduction in interest earnings on that same asset category from 1994 to 1995 resulting from the amortization of carrying value during the period in the amount of $276,000.

Interest expense on Funding Notes and CMOs Payable decreased from $2,430,000 to $1,064,000 for the years ended 1994 and 1995, respectively, as a result of the offsetting balance sheet decline of Funding Notes and CMOs Payable, discussed below. Operating expenses (which includes "Interest on Notes Payable" and "General and Administrative") decreased from $850,000 for 1994 to $590,000 for the comparable period in 1995. This decrease between periods of $260,000 was the result of reduced interest expense on Notes Payable of $109,000 as the Company repaid all amounts outstanding under repurchase agreements during 1994 and had no borrowings during 1995. General and Administrative Expenses declined by $151,000, from $741,000 in 1994 to $590,000 in 1995. General and Administrative Expenses for 1995 include the amortization of $81,000 of deferred expenses related to the Company's investigation of alternative investment activities, specifically tax sale certificates. The balance of these expenses will be completely amortized by the end of the first quarter of 1996, an additional $27,000.

BALANCE SHEET

The Company's assets declined during the twelve month period ended December 31, 1995 by $3,290,000, to a total of $16,602,000 at December 31, 1995. This decrease is attributable to the Company's Mortgage Related Investments declining during the twelve month period from $12,430,000 to $9,814,000, a decrease of

VII-19


$2,616,000. This reduction is primarily the result of prepayments and regularly scheduled principal payments on the underlying Mortgage Collateral.

These asset reductions were matched by a corresponding decrease in the related liability account, Funding Notes Payable, from $12,538,000 to $10,114,000, or a decrease of $2,424,000, which represented regularly scheduled and prepaid mortgage payments.

Mortgage Derivative Securities decreased from $1,990,000 at December 31, 1994 to $1,014,000 at December 31, 1995, a decrease of $976,000, reflecting 1) the amortization and return of the cost basis of the assets held in this category of approximately $276,000 and 2) the writedown of carrying value of such securities which represents additional amortization in 1995 totaling $700,000.

Cash decreased from $4,917,000 to $1,549,000, a decrease of $3,368,000, primarily due to the purchase of Mortgage-Backed Securities during 1995 of $3,400,000. At December 31, 1994, the Company's cash was temporarily invested in liquid short-term U.S. government securities and commercial paper rated in the highest grade by both Standard & Poor's and Moody's Rating Services. As fully described in note 2 of the Company's Consolidated Financial Statements, in order to continue to qualify as an REIT, the Company purchased in 1995 Mortgage-Backed Securities of a nature that qualify under the Real Estate Exception and allow the Company to continue to qualify as an REIT.

Mortgage-Backed Securities consists of one 7% FNMA guaranteed 30 year single-family mortgage pool of which the Company maintains 100% ownership. At December 31, 1995, the FNMA pool is being carried at the Company's cost but is subject to periodic downward valuation adjustments based upon market conditions. At December 31, 1995, the FNMA security had a premium market value.

Funds held by trustee decreased from $172,000 at December 31, 1994 to $159,000 at December 31, 1995. This category of assets represents the receipt of monthly mortgage payments awaiting further payment (reduction) of Funding Notes Payable at a future date. The magnitude of this account is directly affected by the decrease in Mortgage Related Investments discussed above and the level of mortgage prepayments.

Receivables on Mortgage Related Investments and Mortgage Derivative Securities increased from $257,000 at December 31, 1994 to $415,000 at December 31, 1995. Such $158,000 increase is attributable to the level of mortgage prepayments on the underlying mortgage collateral.

Other assets increased from $126,000 at December 31, 1994 to $254,000 at December 31, 1995, related to the deferment of expenses regarding the Company's investigation and analysis of potential business combination or merger opportunities and alternative investment activities. The Company will continue to defer expenses related to its continuing efforts to successfully conclude a business combination. Such deferrals were approximately $89,000 at December 31, 1995.

The Company's Net Loss of $756,000, or $(0.15) per share, for 1995 and its dividend distribution of $0.003 per share, or $16,000, are reflected as increases to the Accumulated Deficit which was $(37,822,000) at December 31, 1995, as compared to $(37,050,000) at December 31, 1994, a total increase of $772,000.

1994 TO 1993 COMPARISONS

STATEMENT OF REVENUES AND EXPENSES

Net Income for the year ended December 31, 1994 was $805,000, or $0.15 per share, as compared to Net Loss of $(25,624,000), or $(4.92) per share, for the year ended December 31, 1993. This substantial improvement in the Company's results from 1993 to 1994 of $26,429,000 was due to 1) drastically larger writedowns in value of Company investments during 1993, 2) larger gains from the sale of assets in 1994 and 3) sharply reduced operating expenses for 1994. Downward asset valuation adjustments in 1993 were $25,569,000, while such writedowns in 1994 were only $285,000, a decrease of $25,284,000. The large magnitude of asset valuation writedowns during 1993 reflected unprecedented actual mortgage prepayment levels and market expectations of a continuation of high prepayment levels. 1994's minor valuation adjustments reflect the dramatic slowdown in prepayment speeds and resultant stabilization in values of securities collateralized by mortgage loans. In 1993, the Company recorded gains on the sale of Mortgage Related Investments of $838,000 and losses on the sale of Marketable Equity Securities of $486,000, for a

VII-20


total net gain of $352,000 from asset sales. In 1994, the Company had total net gains of $1,119,000, of which $461,000 related to the sale of ownership rights in three Mortgage Related Investments and $658,000 related to the sale of six Mortgage Derivative Securities. The difference in sales gains represents an increase of $767,000 in Net Income between periods. The Company also reduced operating expenses from $1,703,000 in 1993 to $850,000 in 1994, a decrease of $853,000. These three substantial improvements, when combined with other minor income reductions on assets between 1993 and 1994, provide for an increase in the Company's Net Income of $26,429,000.

BALANCE SHEET

The Company's assets declined during the twelve month period ended December 31, 1994 by $61,205,000, to a total of $19,892,000 at December 31, 1994. This decrease was attributable to the Company's Mortgage Related Investments declining during the twelve month period from $65,248,000 to $12,430,000, a decrease of $52,818,000. This reduction is primarily the result of 1) the sales, during February 1994, of the ownership rights of two RYMAC IV Bond Series, and during June 1994, of the ownership rights to the Ryland Mortgage Securities Corporation Mortgage Collateralized Bonds Series 1989-6, in order to take advantage of market premiums on the underlying mortgage collateral (such sales reduced Mortgage Related Investments by $40,755,000), 2) substantial prepayments on collateral underlying the Company's remaining Mortgage Related Investments and 3) to a much lesser extent, regularly scheduled principal payments on the underlying mortgage collateral. Such prepayments and scheduled principal payments further reduced Mortgage Related Investments by approximately $12,000,000.

These asset reductions were matched by a corresponding decrease in the related liability accounts, Funding Notes Payable and CMOs Payable, from $69,934,000 to $12,538,000, or a decrease of $57,396,000. The sale of ownership rights includes the transfer of CMO and Funding Note obligations to the buyers while regularly scheduled and prepaid principal on the underlying mortgages serve to retire outstanding obligations secured by such mortgages. The sale of ownership rights reduced CMO and Funding Notes by $42,012,000, while regularly scheduled and prepaid mortgage payments produced approximately $15,400,000 in reductions.

Mortgage Derivative Securities decreased from $7,161,000 at December 31, 1993 to $1,990,000 at December 31, 1994, a decrease of $5,171,000 reflecting 1) the amortization and return of the cost basis of the assets held in this category of approximately $1,335,000, 2) the writedown of carrying value of these securities which represented additional amortization in 1994 totaling $285,000 and 3) the sale of six securities in 1994's third and fourth quarters which removed the cost basis of these six assets totaling $3,551,000 from the balance sheet.

Funds held by trustee decreased from $1,347,000 at December 31, 1993 to $172,000 at December 31, 1994. This category of assets represents the receipt of monthly mortgage payments awaiting further payment (reduction) of Funding Notes and CMOs Payable at a future date.

Receivables on Mortgage Related Investments and Mortgage Derivative Securities declined from $5,608,000 at December 31, 1993 to $257,000 at December 31, 1994. Such $5,351,000 decrease is directly attributable to the sizeable decreases in Mortgage Related Investments and Mortgage Derivative Securities discussed previously.

Notes Payable, consisting solely of repurchase agreements, decreased from $3,814,000 at December 31, 1993 to $0 at December 31, 1994 due primarily to the result of dealer margin calls during 1994 and Kidder Peabody & Company's payment demand on five repurchase agreements, which occurred immediately prior to Paine Webber's acquisition of them during 1994. At November 30, 1994, the Company repaid Kidder Peabody $433,000, reducing its Notes Payable balance to zero.

Net Income for 1994 of $805,000, or $0.15 per share, is reflected as a decrease to the Accumulated Deficit. Such amount decreased from $(37,855,000) at December 31, 1993 to $(37,050,000) at December 31, 1994. Taxable Income was a negative $8,425,000, or $(1.62) per share. Of this amount, $4,811,000 represents capital tax losses related to asset sales during 1994 and $3,614,000 represents operating tax losses. Additionally, $16,000 was reported to the Company as excess inclusion income for 1994 which the Company

VII-21


distributed to stockholders in September 1995. As described above, this distribution represents 1995 taxable income for stockholders. The Company declared no dividend distributions for 1994.

EXPENSES AND USE OF BORROWED FUNDS

Operating expenses (Interest on Notes Payable and General and Administrative) were $850,000 for the year ended December 31, 1994 versus $590,000 for the year ended December 31, 1995, a decline of $260,000. The components of this significant decrease in Operating expenses include: 1) reduced interest costs on Notes Payable, which decreased from $109,000 in 1994 to $0 for 1995, as Notes Payable on the Balance Sheet were paid in full during the fourth quarter of 1994 and 2) a decrease of General and Administrative Expenses from $741,000 in 1994 to $590,000 in 1995, a decline of $151,000 as part of a continuing expense reduction program.

Prior to 1995, the Company had used the proceeds from repurchase agreements to fund a portion of its portfolio of Mortgage Derivative Securities. Prior to April 1994, the Company had also maintained a line of credit used to fund day-to-day operating needs and in past periods to also temporarily fund acquisitions of new investments pending negotiation of repurchase agreements or awaiting return of invested principal.

Until November 1994, the Company had been a party to various repurchase agreements, the proceeds of which had been used to acquire Mortgage Derivative Securities. Such repurchase agreements were secured by substantially all of the Company's Mortgage Derivative Securities.

The Company had maintained a line of credit with a commercial bank for $250,000 which expired on April 30, 1994 and, at the Company's election, was not renewed.

At both December 31, 1995 and December 31, 1994, the total amount borrowed by the Company was $0. The Company is subject to a limitation on the amount of total borrowings of $25,000,000 pursuant to a policy adopted by its Board of Directors in March 1992, although such amount is substantially in excess of the Company's current available credit sources.

During the third quarter and early fourth quarter of 1994, the Company sold six Mortgage Derivative Securities. Since all of these Mortgage Derivative Securities were subject to repurchase agreement financing, their sales required the repayment in full of associated borrowed amounts. The repayment of these repurchase agreements totaled $1,901,000 and reduced repurchase agreement borrowings to $433,000 as of late October 1994. At November 30, 1994, the Company repaid in full its remaining repurchase agreement obligations and has had no outstanding Notes Payable since that date. As such, all of the Company's remaining Mortgage Derivative Securities and Mortgage-Backed Security are available to secure any future borrowings.

The Company believes that the periodic cashflows from its remaining investment portfolio and the significant liquidity existent in its highly liquid cash and Mortgage-Backed Securities positions are sufficient to allow the Company to pursue the several business alternatives it is currently investigating.

REPORT OF INDEPENDENT AUDITORS

To the Board of Directors and Stockholders of RYMAC Mortgage Investment Corporation:

We have audited the consolidated balance sheets of RYMAC Mortgage Investment Corporation and subsidiaries as of December 31, 1995 and 1994, and the related consolidated statements of revenues and expenses, stockholders' equity and cash flows for each year in the three year period ended December 31, 1995. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing standards. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the consolidated financial position of RYMAC Mortgage Investment Corporation and subsidiaries as of December 31, 1995 and 1994, and the consolidated results of their operations and their cash flows for each of the years in the three year period ended December 31, 1995, in conformity with generally accepted accounting principles.

RYMAC MORTGAGE INVESTMENT CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(AMOUNTS IN THOUSANDS EXCEPT SHARE DATA)

NOTE 1--THE COMPANY

RYMAC Mortgage Investment Corporation ("RMIC") was incorporated in Maryland on July 1, 1988. RMIC has two wholly-owned subsidiaries, RYMAC Mortgage Investment I, Inc. ("RMI") and RYMAC Mortgage Investment II, Inc. ("RMII"). RMIC, RMI and RMII are collectively referred to hereafter as the "Company". At inception, the Company issued 5,420,000 shares of its common stock. During 1990 and 1991, the Company repurchased 209,400 shares of its common stock in accordance with a stock repurchase program at costs ranging from $6.75 to $7.63 per share.

The Company and its financial advisor continue the process of identifying and soliciting interest from suitable candidates regarding strategic transactions involving the acquisition of or merger with a profitable growing concern. The successful conclusion of a business combination or merger is subject to financial and economic conditions in the marketplace, the negotiation of mutually acceptable values, the particular requirements of the owners and management of other entities and the existence of competitive offers from entities with greater resources than those of the Company. To date, the Company has not successfully concluded any such discussions.

If the Company is unsuccessful in identifying a transaction that is likely to produce value building results, it may elect to alternatively begin to develop an investment portfolio of financial assets. A decision to pursue such alternative investment activity would be subject to the Company's financial position as well as general economic and financial market conditions prevailing at such time.

NOTE 2--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The consolidated financial statements include the accounts of RMIC and its wholly-owned subsidiaries RMI and RMII. All intercompany balances and transactions have been eliminated in consolidation.

Use of Estimates

The preparation of the financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

Mortgage Related Investments

Mortgage Related Investments are carried at their outstanding principal balance and are designated as available for sale. The net premium on Mortgage Related Investments was amortized over the estimated lives of the investments using the interest method. (See note 4). Due to the sale of several of the Company's Mortgage Related Investments during 1994, the Company determined that the remaining balance of any premiums was nominal and, as such, decided to amortize all premiums at December 31, 1994.

Mortgage Derivative Securities

Mortgage Derivative Securities have been recorded at cost and are amortized over their estimated lives using the interest method. (See note 3)

The Financial Accounting Standards Board ("FASB") issued Financial Accounting Standard No. 115 ("FASB-115"), "Accounting for Certain Investments in Debt and Equity Securities," effective for fiscal years beginning after December 15, 1993. The Company first applied FASB-115 to its December 31, 1993 financial statements. FASB-115 requires that impaired investments be carried at fair market value. Quarterly, the Company projects the expected future cash flows from its Mortgage Derivative Securities under market based assumptions as to future mortgage prepayment speeds and interest rate levels. An impairment to value under

VII-28


NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
(AMOUNTS IN THOUSANDS EXCEPT SHARE DATA)

FASB-115 has occurred if the future cash flows, discounted at a risk free rate (the yield associated with a U.S. Treasury Security with a maturity approximating the average life of the future cash flows from the Company's portfolio of investments), are less than the investment's carrying value.

Mortgage-Backed Securities

Mortgage-Backed Securities have been recorded at the lower of cost or market and are considered held to maturity. At December 31, 1995, the market value was $3,425.

Fair Value

Statement of Financial Accounting Standards No. 107, "Disclosure about Fair Value of Financial Instruments" ("FASB 107"), requires the Company to disclose the fair value of financial instruments for which it is practicable to estimate such value and to disclose the method(s) and assumptions used to estimate such value(s). Each of Notes 3, 4, 5 and 6 discuss the fair value of the Company's Mortgage Derivative Securities, Mortgage Related Investments, Mortgage-Backed Securities and Funding Notes Payable, respectively.

For Mortgage Related Investments, prices for similar mortgage-backed securities were obtained from Wall Street Dealers active in mortgage-backed markets. It is important to note, however, that the current market premiums on such similar mortgage-backed securities are not available to the Company unless and until the Company is able to call for early redemption the Funding Notes that are collateralized by such Mortgage Related Investments. The potential for early redemption (calls) is specific to each underlying collateralized obligation and the indenture covering such transaction. For the Company's three remaining Mortgage Related Investments, the timing of early redemptions are at future dates, the earliest of which is May 1, 1997. As such, no value has been assigned to potential premiums available at early redemption dates.

In regard to Funding Notes Payable, market price quotations for these underlying obligations were obtained from a dealer who actively trades such instruments. Although these instruments currently trade at par or slight premiums in the present financial environment, the Company's obligation thereunder is equal to the face principal amounts without any applicable premiums or discounts.

Investment Restrictions

In addition to qualifying as a Real Estate Investment Trust ("REIT") under the Internal Revenue Code of 1986, as amended (the "Code"), the Company's investment activities are restricted by provisions of the Investment Company Act of 1940, as amended (the "Investment Company Act"). The Investment Company Act specifically exempts entities primarily engaged in the business of purchasing or otherwise acquiring mortgages and other liens and interests in real estate from the definition of an investment company (the "Real Estate Exception"). Under interpretations issued by the staff of the Securities and Exchange Commission, in order to qualify for the Real Estate Exception, the Company must maintain at least 55% of its assets in mortgage loans or certain other interests in real estate, and another 25% of its assets in those or certain other types of real estate related interests.

During 1995, the Company purchased additional assets, specifically mortgage-backed securities. As such, the Company continues to maintain in excess of 55% of its assets in mortgage loans or certain other interests in real estate and, therefore, can continue to rely on the Real Estate Exception to qualify as a REIT under the Code.

If the Company were unable to qualify for the Real Estate Exception or engage in a business other than that of an investment company, it would be required to register as an investment company under the Investment Company Act. The Company is unable to predict how registration under such Act would affect its current plans to pursue new investment activities or business combinations. Registration under the Investment Company Act would also require the investments held by the Company to be adjusted to market value at each

VII-29


NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
(AMOUNTS IN THOUSANDS EXCEPT SHARE DATA)

financial reporting date to the extent not done so already. Other financial statement reporting and disclosure requirements of the Investment Company Act may differ in certain respects from those to which the Company is currently subject.

Federal Income Taxes

The Company has elected to be taxed as a REIT under the Code. As a result, the Company generally will not be subject to federal income taxation at the corporate level to the extent it distributes annually at least 95% of its REIT taxable income, as defined in the Code, to its stockholders and satisfies certain other requirements. Accordingly, no provision has been made for income taxes in the accompanying consolidated financial statements.

Net Income (Loss) Per Share

Net income (loss) per share is computed based on the weighted average number of common shares outstanding during the period.

NOTE 3--MORTGAGE DERIVATIVE SECURITIES

The Company's investments in mortgage derivative securities currently consist of (i) a class or classes of collateralized mortgage obligations ("CMOs") that either represents a regular class of bonds or a residual class of bonds or (ii) interests in a class or classes of mortgage-backed pass-through certificates that either represent a regular class of certificates or a residual class of certificates. For federal income tax purposes, a majority of the Company's Mortgage Derivative Securities represent interests in real estate mortgage investment conduits ("REMICs"). CMOs are mortgage-backed bonds which bear interest at a specific predetermined rate or at a rate which varies according to a specified relationship to a specific short term interest rate index, such as the London interbank offered rate for one-month U.S. dollar deposits ("LIBOR").

Most residual bonds are structured so as to entitle the holder to receive a proportionate share of the excess (if any) of payments received from the collateral pledged to secure such bonds and the other related classes, together with the reinvestment income thereon, over amounts required to make debt service payments on such CMOs and to pay related administrative expenses. In connection with these investments, the Company acquired no other rights relating to the collateral pledged to secure its Mortgage Derivative Securities. Most residual certificates are structured so as to entitle the Company to receive a specified percentage of the distributions generated from the pool of assets comprising the trust funds of which the certificates evidence an interest.

At December 31, 1995 and 1994, the Company had net investments in Mortgage Derivative Securities as set forth below:

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
(AMOUNTS IN THOUSANDS EXCEPT SHARE DATA)

The Company makes valuation adjustments at quarterly dates based upon assumptions as to mortgage prepayment speeds, interest rates and discount rates reflective of then current financial markets.

Under FASB-115, future cash flows are discounted at a rate reflective of market yields for assets of the type held by the Company. At December 31, 1995, the Company applied a discount rate of 16% to the cash flows for its portfolio of Mortgage Derivative Securities and at December 31, 1994, a 12% discount rate was applied to most assets. At December 31, 1995, all assets in this category were providing yields in a range of 18%-30%. Yields in excess of 16% were utilized to fund a valuation reserve account in order to provide for future downward valuation adjustments. At December 31, 1995, the valuation reserve account had a balance of $39. At December 31, 1994, the balance of the valuation reserve account was utilized to reduce the value of certain assets. Total valuation adjustments for 1994 were $285 as compared with $700 for 1995, all of which was incurred during the second quarter of 1995.

Additionally, in accordance with FASB-107, the Company is required to compute the estimated fair value of its Mortgage Derivative Securities by projecting anticipated future cash flows and discounting those cash flows at discount rates established in market transactions for securities having similar characteristics and backed by collateral of similar rate and term.

For the December 31, 1995 estimate of fair market values, the Company used the same prepayment and interest rate assumptions as for its determination of carrying values under FASB-115. (See note 2) The PSA speeds vary depending on the collateral. The prepayment assumption model used by the Company incorporates a market methodology established by the Public Securities Association ("PSA"). Such model assumes a rate of prepayment each month of the unpaid principal balance of a pool of mortgage loans. 100% of PSA assumes that 0.2% per annum of the then outstanding principal balance of a pool of mortgage loans will prepay in the first month of the life of such mortgage loans and an additional 0.2% per annum in each month thereafter (for example, 0.4% per annum in the second month, 0.6% in the third month, etc.) until the 30th month. Beginning with the 30th month and in each month thereafter, 100% PSA assumes a constant prepayment rate of 6% per annum of the then outstanding principal balance of such mortgage loans. On a bi-weekly basis, Bloomberg Financial Markets ("Bloomberg") obtains PSA estimates for a wide range of mortgage coupons and ages from several dealers in mortgage derivative securities and makes them available to Bloomberg's subscribers.

The prepayment speeds used by the Company in establishing the estimated fair value of its securities at December 31, 1995 are:

   COLLATERAL/(YEAR OF            BLOOMBERG MEDIAN PSA
         ISSUE)                 AS OF DECEMBER 31, 1995
         ------                 -----------------------
GNMA 9.5%        (1986)                   298%
FNMA/FHLMC 9.0   (1986)                   333
FNMA/FHLMC 9.0   (1991)                   331
FNMA/FHLMC 9.5   (1986)                   331

Such PSA assumptions do not purport to be an historical description of prepayment experience or a prediction of the future rate of prepayments of any mortgage loan.

All assets were modeled forward using the December 31, 1995 Bloomberg Median PSA for the life of each asset. LIBOR was assumed at 5.625% for the life of the assets and various discount rates were applied. The resulting analysis indicated that the fair value of all of the Company's Mortgage Derivative Securities was in excess of their carrying value at December 31, 1995.

None of the Company's Mortgage Derivative Securities are pledged as collateral for any borrowings and thus represent a source of increased liquidity to the Company.

NOTE 4--MORTGAGE RELATED INVESTMENTS

The Company's Mortgage Related Investments consist of ownership interests in certain classes of mortgage-backed securities issued by Ryan Mortgage Acceptance Corporation IV (as described below).

On September 23, 1988, the Company purchased from Ryan Mortgage Acceptance Corporation IV ("RYMAC IV") certain GNMA certificates and FNMA certificates and other collateral owned by RYMAC IV and pledged to secure RYMAC IV's Mortgage Collateralized Bonds (the "RYMAC IV Bonds"). (See note 6) These Mortgage Related Investments and other collateral were purchased subject to the lien of the Indenture between RYMAC IV and the Trustee (the "RYMAC IV Indenture") pursuant to which the RYMAC IV Bonds were issued and subject to the rights of the Trustee and the bondholders thereunder. (See note 6) The purchase agreements grant to the Company certain additional rights with respect to the RYMAC IV Bonds, such as the right, if any, to substitute collateral, the right to direct the reinvestment of collateral proceeds and the right to call the related RYMAC IV Bonds. At December 31, 1995, the Company's Mortgage Related Investments consist of RYMAC IV Bonds, Series 7, 10 and 19.

During the first quarter of 1994, the Company sold certain ownership rights in the RYMAC IV Bonds for a net gain of approximately $595. (See note 6) For the remaining RYMAC IV Bonds the Company is investigating the possible contractual assignment of the Company's rights. Additionally, the Company assigned its ownership rights in the Ryland Mortgage Securities Corporation Mortgage Collateralized Bonds Series 1989-6 to a third party during the second quarter of 1994 and realized a net loss of approximately $134. No such sales or assignments occurred during 1995.

At December 31, 1995 and 1994, the Company owned Mortgage Related Investments with aggregate outstanding principal balances of $9,814 and $12,430, respectively, which provide for monthly principal and interest payments. The RYMAC IV collateral bears interest at rates ranging from 7.75% to 10.50% and have scheduled maturity dates ranging from July 1, 2001 to April 1, 2017.

The Company held the following Mortgage Related Investments as of December 31, 1995:

The following is a summary of total Mortgage Related Investments for the years ended December 31, 1995 and 1994:

                                                          =======     ========

In accordance with FASB-107, the Company obtained prices from a Wall Street Dealer for the mortgage-backed securities collateralizing the Company's Mortgage Related Investments.

Although the FNMA Certificates were trading at premiums to their face values as of December 31, 1995, as described in note 2, the premiums on these FNMA Certificates are only available to the Company under limited circumstances related to early redemption of specific series of bonds.

The Company estimates the fair value of the RYMAC IV Bond Series 7, 10 and 19 to equal the carrying values at December 31, 1995 and 1994.

VII-32


NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
(AMOUNTS IN THOUSANDS EXCEPT SHARE DATA)

NOTE 5--MORTGAGE-BACKED SECURITIES

Mortgage-Backed Securities have been recorded at the lower of cost or market. The fair value of the Company's Mortgage-Backed Securities were at a premium to the carrying value at December 31, 1995. However, since such assets are being held for investment purposes, no unrealized gains have been recognized.

NOTE 6--FUNDING NOTES PAYABLE

Funding Notes Payable represent limited recourse notes delivered to RYMAC IV as partial payment for the purchase of Mortgage Related Investments and other collateral, and have payment terms the same as the related series of RYMAC IV Bonds. (See note 4) The Funding Notes Payable consisted of three multi-class series at December 31, 1995 and 1994 having stated maturities ranging from August 1, 2016 to May 1, 2017 and August 1, 2010 to May 1, 2017, respectively. The classes of each series of Funding Notes Payable bear interest at fixed rates. The range of fixed rates at December 31, 1995 and 1994 were 8.25% to 9.45%.

Principal and interest payments on the Mortgage Related Investments are used to make the monthly or quarterly payments on the funding notes payable. In addition, prepayments of the underlying mortgage related investments are passed through as prepayments of the Funding Notes Payable so that the Funding Notes Payable may be fully paid prior to their stated maturities.

In accordance with FASB-107, the Company obtained prices for its Funding Notes Payable as of December 31, 1995 and 1994, from a dealer actively trading in RYMAC IV Bonds and other bonds of this type. Such bonds were trading at par or slight premiums to their face values as of December 31, 1995 and 1994. Market premiums (or discounts) on trades of these obligations do not affect the Company. The Company's obligations for repayment of its Funding Notes Payable are at par through receipt of principal and interest payments on its Mortgage Related Investments.

NOTE 7--FEDERAL INCOME TAXES AND DISTRIBUTIONS

As described in note 2, the Company has elected to be treated for federal income tax purposes as a REIT. As such, the Company is required to distribute annually, in the form of dividends to its stockholders, at least 95% of its taxable income. Because of the provisions of the Code applicable to the type of investments made by the Company, in the early years of the life of certain of the Company's initial investments (particularly investments made in connection with the Company's initial public offering, and to a lesser degree during 1989) taxable income exceeded net income.

During the later years of such ownership, Net Income will exceed REIT taxable income. The principal reason for such difference is that the Company reports income from its portfolio of Mortgage Related Investments and Mortgage Derivative Securities on the interest method for financial reporting purposes; however, for income tax purposes, the Company reports its proportionate share of the difference between interest income generated by the collateral and interest expense on the CMOs. More recent investments made by the Company and investments currently available in the market are typically structured so that taxable income and Net Income are similar during each reporting period. Over the life of a particular investment or security, taxable income and Net Income will be equal. In reporting periods where taxable income exceeds Net Income, stockholders' equity will be reduced by the amount of dividends in excess of Net Income in such period and will be increased by the excess of Net Income over dividends in future reporting periods.

For 1995, the Company made a distribution of $0.003 per share to its stockholders on September 29, 1995, with a record date of September 20, 1995. The dividend represented excess inclusion income. The Company expects to have a tax loss of approximately $625 for the year. The Company's taxable losses through 1995 aggregate to approximately $36 million. During 1994, the Company's investment in certain REMICs produced excess inclusion income of $16. For 1995, the Company's investments did not generate any excess inclusion income. Under the Code, a REIT must generally distribute its excess inclusion income to its stockholders even though it has other losses or deductions exceeding such excess inclusion income.

VII-33


NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
(AMOUNTS IN THOUSANDS EXCEPT SHARE DATA)

Accordingly, if the Company were to report future excess inclusion income, it may elect to distribute such excess inclusion income as dividends even though it has an estimated tax loss carryforward approximating $36 million, including approximately $5 million in capital loss carryforwards. The tax losses can be carried forward to offset future income of the Company.

NOTE 8--RELATED PARTY TRANSACTIONS

Pursuant to the Purchase Agreements between the Company and RYMAC IV (see note 4), $27 has been withheld from amounts released from the lien of the RYMAC IV Indenture, retained by RYMAC IV and deposited in escrow to be used for payment of expenses of the CMOs secured by certain of the Mortgage Related Investments purchased by the Company. In addition, during the year ended December 31, 1995, the Company incurred $14 of CMO administration fees which were paid to RYMAC IV under the terms of the Purchase Agreements.

NOTE 9--EMPLOYEE BENEFITS

The Company's Board of Directors has established a Salary Reduction-Simplified Employee Pension Program ("SAR-SEP") for its full-time employees. A SAR-SEP is a minimal administration 408-K Plan (similar to a 401-K) for companies with fewer than 25 employees.

For 1995, the Company contributed 3% of gross compensation and has established the same minimum contribution for 1996. Company contributions to the plan may vary and the Company is not required to continue the program. Employee contributions are based upon established formulas under the Employee Retirement Income Security Act ("ERISA") rules governing 408-K Plans.

The Unaffiliated Directors adopted an incentive stock option program during 1994 for the Company's two Officers and Affiliated Director. Under the Stock Option Program, options on 260,000 shares of the Company's Common Stock were awarded at market prices, exercisable over ten year periods ending May 2005. The Company accounts for stock option grants in accordance with APB Opinion No. 25, "Accounting for Stock Issued to Employees," and, accordingly, recognizes no compensation expense for the stock option grants. In addition, a salary continuance program was provided to the Company's officers, allowing for up to one year's base salary following the consummation of a business combination.

RYMAC MORTGAGE INVESTMENT CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(amounts in thousands except share data)

NOTE 1--THE COMPANY

RYMAC Mortgage Investment Corporation ("RMIC") was incorporated in Maryland on July 1, 1988. RMIC has two wholly-owned subsidiaries, RYMAC Mortgage Investment I, Inc. ("RMI") and RYMAC Mortgage Investment II, Inc. ("RMII"). RMIC, RMI and RMII are collectively referred to hereafter as the "Company". At inception, the Company issued 5,420,000 shares of its common stock. During 1990 and 1991, the Company repurchased 209,400 shares of its common stock in accordance with a stock repurchase program at costs ranging from $6.75 to $7.63 per share.

On May 15, 1996, the Company and Navistar International Transportation Corp. ("Navistar") announced that they had reached a non-binding agreement in principle dated May 13, 1996 (the "Agreement in Principle") with respect to the purchase by the Company (the "Acquisition") of Navistar's Columbus Plastics Operation ("Columbus Plastics"), which manufactures large sheet molding compound ("SMC") components and is located in Columbus, Ohio.

The obligation of either party to proceed with the Acquisition is subject to the negotiation and execution by the Company and Navistar of a mutually acceptable definitive purchase agreement. The Agreement in Principle contemplated that the parties would work diligently to complete and sign such an agreement by May 31, 1996. Since the parties have not reached agreement by May 31, 1996, either is free to terminate negotiations by the terms of the Agreement in Principle. The parties are nonetheless continuing to negotiate the terms of a possible transaction. In the event an agreement is executed, consummation of the transaction will be subject to approval by the Board of Directors of each of the Company and Navistar, approval by the Company's stockholders, and such other terms and conditions as may be set forth in such purchase agreement. If an agreement is successfully concluded and all conditions set forth therein are satisfied, it is expected that the Acquisition will be consummated in fall 1996.

NOTE 2--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The consolidated financial statements include the accounts of RMIC and its wholly-owned subsidiaries RMI and RMII. All intercompany balances and transactions have been eliminated in consolidation.

Use of Estimates

The preparation of the financial statements in conformity with generally accepted accounting principles ("GAAP") requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

Mortgage-Backed Securities

Mortgage-Backed Securities have been recorded at the lower of cost or market and are considered held to maturity. At June 30, 1996, the cost exceeded the market value by $128. An allowance for unrealized losses and a separate component of stockholders' equity has been recorded.

Investment Restrictions

In addition to qualifying as a Real Estate Investment Trust ("REIT") under the Internal Revenue Code of 1986, as amended (the "Code"), the Company's investment activities are currently restricted by provisions of the Investment Company Act of 1940, as amended (the "Investment Company Act"). The Investment Company Act specifically exempts entities primarily engaged in the business of purchasing or otherwise acquiring mortgages and other liens and interests in real estate from the definition of an investment company (the "Real Estate Exception"). Under interpretations issued by the staff of the Securities and Exchange

VIII-6


NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

(amounts in thousands except share data)

NOTE 2--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)
Commission, in order to qualify for the Real Estate Exception, the Company must maintain at least 55% of its assets in mortgage loans or certain other interests in real estate, and another 25% of its assets in those or certain other types of real estate related interests.

During 1995, the Company purchased additional assets, specifically mortgage-backed securities. As such, the Company continues to maintain in excess of 55% of its assets in mortgage loans or certain other interests in real estate and, therefore, can continue to rely on the Real Estate Exception to avoid registration as an investment company under the Investment Company Act.

If the Acquisition described in Note 1 above is consummated, the Company will no longer be required to rely upon the Real Estate Exception in order to avoid being subject to the provisions of the Investment Company Act.

Federal Income Taxes

The Company has elected to be taxed as a REIT under the Code. As a result, the Company generally will not be subject to federal income taxation at the corporate level to the extent it distributes annually at least 95% of its REIT taxable income, as defined in the Code, to its stockholders and satisfies certain other requirements. Accordingly, no provision has been made for income taxes in the accompanying consolidated financial statements.

If the Acquisition described in Note 1 above is consummated, the Company will no longer qualify as a REIT and will be taxed as a corporation under subchapter C of Chapter 1 of the Code.

Net Income (Loss) Per Share

Net income (loss) per share is computed based on the weighted average number of common shares outstanding during the period.

NOTE 3--MORTGAGE DERIVATIVE SECURITIES

Prior to June 30, 1996, the Company had investments in mortgage derivative securities, which consisted of (i) a class or classes of collateralized mortgage obligations ("CMOs") that either represented a regular class of bonds or a residual class of bonds or (ii) interests in a class or classes of mortgage-backed pass-through certificates that either represented a regular class of certificates or a residual class of certificates. For federal income tax purposes, a majority of the Company's Mortgage Derivative Securities represented interests in real estate mortgage investment conduits ("REMICs"). CMOs are mortgage-backed bonds which bear interest at a specific predetermined rate or at a rate which varies according to a specified relationship to a specific short term interest rate index, such as the London interbank offered rate for one-month U.S. dollar deposits ("LIBOR").

Most residual bonds are structured so as to entitle the holder to receive a proportionate share of the excess (if any) of payments received from the collateral pledged to secure such bonds and the other related classes, together with the reinvestment income thereon, over amounts required to make debt service payments on such CMOs and to pay related administrative expenses. In connection with these investments, the Company acquired no other rights relating to the collateral pledged to secure its Mortgage

Derivative Securities. Most residual certificates are structured so as to entitle the Company to receive a specified percentage of the distributions generated from the pool of assets comprising the trust funds of which the certificates evidence an interest.

The Company sold its remaining Mortgage Derivative Securities during the second quarter of 1996 for $785 and recorded a net gain of $79 during the quarter.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

(amounts in thousands except share data)

NOTE 3--MORTGAGE DERIVATIVE SECURITIES (continued)
During the first quarter, the Company sold one Mortgage Derivative Security for $368 and recorded a net gain of $76. The proceeds from these sales will be directed toward the new business activities which the Company is currently investigating.

NOTE 4--MORTGAGE RELATED INVESTMENTS

Prior to June 30, 1996, the Company maintained a portfolio which included Mortgage Related Investments, consisting of ownership interests in certain classes of mortgage-backed securities issued by Ryan Mortgage Acceptance Corporation IV (as described below).

On September 23, 1988, the Company purchased from Ryan Mortgage Acceptance Corporation IV ("RYMAC IV") certain GNMA certificates and FNMA certificates and other collateral owned by RYMAC IV and pledged to secure RYMAC IV's Mortgage Collateralized Bonds (the "RYMAC IV Bonds"). (See note 6) These Mortgage Related Investments and other collateral were purchased subject to the lien of the Indenture between RYMAC IV and the Trustee (the "RYMAC IV Indenture") pursuant to which the RYMAC IV Bonds were issued and subject to the rights of the Trustee and the bondholders thereunder. The purchase agreements grant to the Company certain additional rights with respect to the RYMAC IV Bonds, such as the right, if any, to substitute collateral, the right to direct the reinvestment of collateral proceeds and the right to call the related RYMAC IV Bonds. At December 31, 1995, the Company's Mortgage Related Investments consisted of RYMAC IV Bonds, Series 7, 10 and 19.

During the second quarter of 1996, the Company sold its ownership rights in the RYMAC IV Series 7, 10 and 19 Bonds for a net loss of $202. (See note 6)

NOTE 5--MORTGAGE-BACKED SECURITIES

Mortgage-Backed Securities have been recorded at the lower of cost or market. The market value of the Company's Mortgage-Backed Securities were at a discount to the carrying value at June 30, 1996. An allowance for unrealized losses was established at March 31, 1996. A separate component of stockholders' equity has been reduced by $128, accordingly.

NOTE 6--FUNDING NOTES PAYABLE

Funding Notes Payable represented limited recourse notes delivered to RYMAC IV as partial payment for the purchase of Mortgage Related Investments and other collateral, and had payment terms the same as the related series of RYMAC IV Bonds. (See note 4)

Principal and interest payments on the Mortgage Related Investments were used to make the quarterly payments on the funding notes payable. In addition, prepayments of the underlying mortgage related investments were passed through as prepayments of the Funding Notes Payable so that the Funding Notes Payable could be fully paid prior to their stated maturities.

During the second quarter of 1996, the Company sold its ownership interest in the RYMAC IV Series 7, 10 and 19 Bonds. As a result of the sale of these ownership interests, the related liability account, Funding Notes Payable, was reduced to $0. (See note 4)

NOTE 7--FEDERAL INCOME TAXES AND DISTRIBUTIONS

As described in note 2, the Company has elected to be treated for federal income tax purposes as a REIT. As such, the Company is required to distribute annually, in the form of dividends to its stockholders, at least 95% of its taxable income. Because of the provisions of the Code applicable to the type of investments made by the Company, in the early years of the life of certain of the Company's initial investments (particularly

VIII-8


NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

(amounts in thousands except share data)

NOTE 7--FEDERAL INCOME TAXES AND DISTRIBUTIONS (continued)
investments made in connection with the Company's initial public offering, and to a lesser degree during 1989) taxable income exceeded net income.

During the later years of such ownership, Net Income will exceed REIT taxable income. The principal reason for such difference is that the Company reports income from its portfolio of Mortgage Related Investments and Mortgage Derivative Securities on the interest method for financial reporting purposes; however, for income tax purposes, the Company reports its proportionate share of the difference between interest income generated by the collateral and interest expense on the CMOs. More recent investments made by the Company and investments currently available in the market are typically structured so that taxable income and Net Income are similar during each reporting period. Over the life of a particular investment or security, taxable income and Net Income will be equal. In reporting periods where taxable income exceeds Net Income, stockholders' equity will be reduced by the amount of dividends in excess of Net Income in such period and will be increased by the excess of Net Income over dividends in future reporting periods.

During the first and second quarter of 1996, no dividend distributions were made. The Company's taxable losses through 1995 aggregate to approximately $36 million. Under the Code, a REIT must generally distribute its excess inclusion income to its stockholders even though it has other losses or deductions exceeding such excess inclusion income. Accordingly, if the Company were to report future excess inclusion income, it may elect to distribute such excess inclusion income as dividends even though it has an estimated tax loss carryforward approximating $36 million, including approximately $5 million in capital loss carryforwards. The tax losses can be carried forward to offset future income of the Company.

If the Acquisition described in Note 1 above is consummated, the Company will no longer qualify as a REIT and will be taxed as a corporation under subchapter C of Chapter 1 of the Code.

NOTE 8--RELATED PARTY TRANSACTIONS

Pursuant to the Purchase Agreements between the Company and RYMAC IV (see note 4), $15 has been withheld from amounts released from the lien of the RYMAC IV Indenture, retained by RYMAC IV and deposited in escrow to be used for payment of expenses of the CMOs secured by certain of the Mortgage Related Investments purchased by the Company. In addition, during the quarter ended June 30, 1996, the Company incurred $7 of CMO administration fees which were paid to RYMAC IV under the terms of the Purchase Agreements.

NOTE 9--EMPLOYEE BENEFITS

The Company's Board of Directors has established a Salary Reduction-Simplified Employee Pension Program ("SAR-SEP") for its full-time employees. A SAR-SEP is a minimal administration 408-K Plan (similar to a 401-K) for companies with fewer than 25 employees.

For 1996, the Company has established a minimum contribution of 3% of gross compensation. Company contributions to the plan may vary and the Company is not required to continue the program. Employee contributions are based upon established formulas under the Employee Retirement Income Security Act ("ERISA") rules governing 408-K Plans.

The Unaffiliated Directors adopted an incentive stock option program during 1994 for the Company's two Officers and Affiliated Director. Under the Stock Option Program, options on 260,000 shares of the Company's Common Stock were awarded at market prices, exercisable over ten year periods ending May 2005. The Company accounts for stock option grants in accordance with APB Opinion No. 25, "Accounting for Stock Issued to Employees", and, accordingly, recognizes no compensation expense for the stock option grants. In addition, a salary continuance program was provided to the Company's officers, allowing for up to one year's base salary following the consummation of a business combination.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

RECENT DEVELOPMENTS

On May 15, 1996, RYMAC Mortgage Investment Corporation (the "Company") and Navistar International Transportation Corp. ("Navistar"), the principal operating subsidiary of Navistar International Corporation, announced that they had reached a non-binding agreement in principle dated May 13, 1996 (the "Agreement in Principle") with respect to the purchase by the Company (the "Acquisition") of Navistar's Columbus Plastics Operation, which manufactures large sheet molding compound components and is located in Columbus, Ohio. A copy of the Agreement in Principle was filed with the Securities and Exchange Commission by the Company on May 22, 1996 as an exhibit to a Current Report on Form 8-K.

The obligation of either party to proceed with the Acquisition is subject to the execution by the Company and Navistar of a mutually acceptable definitive purchase agreement. The Agreement in Principle contemplated that the parties would work diligently to complete and sign such an agreement by May 31, 1996. Since the parties have not reached agreement by May 31, 1996, either is free to terminate negotiations by the terms of the Agreement in Principle. The parties are nonetheless continuing to negotiate the terms of a possible transaction.

It is currently contemplated that the consideration for the Acquisition would consist of newly issued common stock of the Company and a promissory note of the Company, together with certain contingent payments to Navistar should the Company's earnings exceed certain preestablished levels. It is further contemplated that Navistar would become the Company's largest stockholder and have substantial representation on the Company's board of directors. The Company would further expect to enter into a long-term supply contract with Navistar to supply fiberglass reinforced plastic parts for Navistar's truck assembly business.

In the event a definitive agreement is executed, consummation of the transaction would be subject to approval by the Board of Directors of each of the Company and Navistar, approval by the Company's stockholders, and such other terms and conditions as may be set forth in a purchase agreement. If an agreement is executed and all conditions set forth therein are satisfied, the Company presently anticipates that the Acquisition would be consummated in fall 1996.

If the Company is unsuccessful in concluding the Acquisition described above, it may elect to continue to seek a suitable candidate with which to effect a business combination or, alternatively to begin to develop an investment portfolio of financial assets as a means of increasing value to stockholders. A decision to pursue such alternative investment activity would be subject to the Company's financial position as well as general economic and financial market conditions prevailing at such time.

The Company and its financial advisor continue to believe that the future potential earnings and value building aspects of utilizing its assets in a successful business combination outweigh those of rebuilding an investment portfolio containing lower-risk assets than those previously composing the Company's investment portfolio.

In anticipation of an acquisition of Columbus Plastics, the Company sold the majority of its remaining mortgage assets during the second quarter of 1996.
(See Results of Operations)

DIVIDEND POLICY

In accordance with the Code, the Company is required to distribute at least 95% of its taxable income to its stockholders each year in order to maintain its status as a REIT. Dividends paid for a fiscal year in excess of the Company's taxable income are reported as a return of capital to the Company's stockholders, except as provided below.

Historically, some of the Company's investments constituted REMIC residual interests. Certain of these residual interests may produce "excess inclusion" income during the fiscal year. The Code requires that excess inclusion income be included in a taxpayer's income even though the taxpayer has current or prior losses that would otherwise offset such income. As a result, the Company could have taxable income from excess inclusions in a taxable year even though it has current or prior losses from other investments that would

VIII-10


normally be sufficient to offset the amount of such excess inclusion income. The Company is required to distribute the taxable income representing excess inclusions to meet its 95% distribution requirement and to avoid a corporate level tax on such income. When such income is distributed to a stockholder, the stockholder will have taxable income, rather than a return of capital, equal to its share of such excess inclusion income during the fiscal year. For a stockholder, generally, excess inclusion income cannot be offset by losses.

For the tax year ended December 31, 1995, the Company paid a dividend of $0.003 per share on September 29, 1995 to stockholders of record on September 20, 1995. This 1995 dividend was the result of excess inclusion income and is reportable by stockholders as taxable income for 1995. The Company paid no dividend for the first or second quarters of 1996.

If the Acquisition described in note 1 to the Company's Consolidated Financial Statements and "Recent Developments" is consummated, the Company will no longer qualify as a REIT and will be taxed as a corporation under subchapter C of Chapter 1 of the Code. As a result, the Company will no longer be entitled to any deduction for dividends paid to stockholders. No assurances can be given as to the dividends, if any, that may be declared by the Board of Directors of the Company following such Acquisition.

RESULTS OF OPERATIONS

The Company's Net Loss declined from $724,000 for the six month period ended June 30, 1995 to a Net Loss of $74,000 for the six month period ended June 30, 1996, a decrease of $650,000. This decline is attributable to the Company's incurring $700,000 in asset valuation writedowns during the 1995 period while no writedowns were required for the first six months of 1996, offset in part by the existence of a net loss from the sale of assets of $47,000 in 1996's period as compared to no such loss in the 1995 period.

Without the net loss recorded from the sale of assets in 1996's first half, the Company's loss for such period would have been reduced to $27,000.

STATEMENT OF REVENUES AND EXPENSES

Net Income (loss), as calculated in accordance with GAAP and as presented in the accompanying consolidated financial statements, was $(74,000), or $(0.02) per share, for the six months ended June 30, 1996 as compared with $(724,000), or $(0.14) per share, for the six months ended June 30, 1995, and $(100,000), or $(0.02) per share, for the three months ended June 30, 1996 as compared to $(720,000), or $(0.14) per share, for the three months ended June 30, 1995.

Interest revenue on Mortgage Related Investments decreased from $561,000 for the six months ended June 30, 1995 to $369,000 for the six months ended June 30, 1996, as a result of the reduction in Mortgage Related Investments on the Company's Balance Sheet, which decreased from an average outstanding of $11,912,000 during 1995's first six months to an average outstanding of $4,907,000 during the first six months of 1996. Interest revenue on Mortgage Derivative Securities was $(570,000) for the six months ended June 30, 1995 as compared to $72,000 for the six months ended June 30, 1996. This $642,000 increase in interest revenue was the result of the valuation writedown of assets equal to $700,000 in 1995's second quarter as compared with no such writedown in the first half of 1996. Such writedowns are reflected as a decrease to interest revenues on Mortgage Derivative Securities during the period incurred.

Income from Temporary investments decreased from $165,000 for the six months ended June 30, 1995 to $51,000 for the six months ended June 30, 1996 due to the Company's purchase of one 7% FNMA guaranteed 30-year single family mortgage pool of which the Company maintains 100% ownership since 1995's fourth quarter. This Mortgage-Backed Security carried as a separate investment category produced $119,000 of interest revenues during the 1996 period.

In anticipation of the transaction with Navistar described in note 1 to the Company's Consolidated Financial Statements and "Recent Developments", the Company sold during the March-June 1996 time period all of its remaining Mortgage Related Investments and Mortgage Derivative Securities. Nine Mortgage Derivative Securities were sold for net cash proceeds of $1,153,000, representing prices that exceeded the Company's carrying value by $155,000 and was recognized as a gain during the 1996 period. Also, the Company sold its ownership interests (including early redemption rights) in its three remaining Mortgage

VIII-11


Related Investments (RYMAC IV, Series 7, 10 and 19). The sale transaction relating to the RYMAC IV assets included the Company's transfer of the future obligation for payment of quarterly administrative costs to the purchaser. Such administrative costs approximated $12,500 per annum over the next five and one-half years. The sale of the Company's ownership rights, including ongoing administrative costs, in its Mortgage Related Investments resulted in the Company recording a loss on such transaction of $202,000 during the 1996 period.

The Company also recognized $35,000 in revenues during the 1996 period reflecting the reversal of a provision for future losses on Mortgage Derivative Securities that was no longer necessary given the sale of the Company's remaining assets carried in this category.

Interest expense on Funding Notes Payable decreased from $558,000 to $368,000 for the six months ended June 30, 1995 and 1996, respectively, as a result of the substantial offsetting balance sheet decline of Funding Notes Payable, which decreased from average outstandings of $12,160,000 to $5,057,000 for the six months ended June 30, 1995 and 1996, respectively. General and Administrative expenses decreased slightly from $322,000 for 1995's first six months to $305,000 in 1996's first six months as the Company maintained a minimal staff while continuing its efforts to identify and conclude a business combination.

BALANCE SHEET

The Company's assets declined by $10,472,000 during the six month period ended June 30, 1996, dropping from $16,602,000 to a total of $6,130,000 at June 30, 1996. This decrease is attributable to the Company's sale of its remaining Mortgage Related Investments and Mortgage Derivative Securities during the six month period ended June 30, 1996 and, to a minor extent, reductions resulting from principal payments on the mortgage collateral underlying the Company's Mortgage Related Investments and amortization of the cost basis in its Mortgage Derivative Securities.

Concurrently, Funds Held by Trustee and Receivables on both Mortgage Related Investments and Mortgage Derivative Securities decreased from $159,000 and $415,000, respectively at December 31, 1995 to $0 in both categories at June 30, 1996, as both of these assets categories were associated with the sale of the Company's remaining Mortgage Related and Mortgage Derivative holdings.

The sale of Mortgage Related Investments caused the related liability account, Funding Notes Payable, to decrease from $10,114,000 to $0, between December 31, 1995 and June 30, 1996.

The two liability accounts, Accrued Interest on Funding Notes Payable and Other Liabilities, decreased in total by $156,000, primarily reflecting the sale of the corresponding liability account, Funding Notes Payable, related to the sale of Mortgage Related Investments described above.

The Company's Accumulated Deficit increased slightly from $(37,822,000) at December 31, 1995 to $(37,896,000) at June 30, 1996 due to the Net Loss incurred for the period of $74,000. Additionally, the Company's net worth was negatively affected by the GAAP requirement to carry a valuation account, Unrealized Loss on Mortgage-Backed Securities, for the Company's Mortgage-Backed Securities, valuing the asset at the lower of cost or market. This Unrealized Loss of $128,000 reflects the loss that would have been recognized if the Company had elected to sell its entire Mortgage-Backed Securities holding at June 30, 1996.

EXPENSES AND USE OF BORROWED FUNDS

Operating expenses, "General and Administrative", were $322,000 for the six months ended June 30, 1995 versus $305,000 for the six months ended June 30, 1996. These low expense levels are reflective of the Company's minimal staffing and cost reduction efforts while continuing its efforts to conclude a business combination.

The Company has had no borrowings since November 30, 1994.

LIQUIDITY AND CAPITAL RESOURCES

At both December 31, 1995 and June 30, 1996, the total amount borrowed by the Company was $0. The Company is subject to a limitation on the amount of total borrowings of $25,000,000 pursuant to a policy

VIII-12


adopted by its Board of Directors in March 1992, although such amount is substantially in excess of amounts that could currently be borrowed by the Company.

All of the Company's remaining Mortgage-Backed Securities are available to secure future borrowings. The Company estimates that either the approximate $3,000,000 in borrowing value or $3,300,000 from the current market sale value of the Company's Mortgage-Backed Securities in conjunction with its cash reserves of approximately $2,700,000, currently held in high quality short-term instruments, provide the Company with sufficient liquidity with which to pursue its proposed business activities. (See "Recent Developments")

If the Acquisition described in note 1 to the Company's Consolidated Financial Statements and "Recent Developments" above is consummated, additional liquidity to fund working capital requirements of the Company will be needed. The Company intends to seek additional working capital funding prior to the consummation of the Acquisition in order to fund such requirements. No assurances can be given that the Company will be successful in obtaining such funding.

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

Section 145 of the Delaware General Corporation Law (the "DGCL") permits the Registrant's board of directors to indemnify any person against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him in connection with any threatened, pending or completed action, suit or proceeding in which such person is made a party by reason of his being or having been a director, officer, employee or agent of the Registrant, in terms sufficiently broad to permit such indemnification under certain circumstances for liabilities (including reimbursement for expenses incurred) arising under the Securities Act of 1933, as amended (the "Securities Act"). The statute provides that indemnification pursuant to its provisions is not exclusive of other rights of indemnification to which a person may be entitled under any bylaw, agreement, vote of stockholders or disinterested directors, or otherwise.

The Registrant's Bylaws provide for indemnification of its directors and officers to the fullest extent permitted by law.

As permitted by sections 102 and 145 of the DGCL, the Registrant's Certificate of Incorporation eliminates a director's personal liability for monetary damages to the Registrant and its stockholders arising from a breach or alleged breach of a director's fiduciary duty except for liability under section 174 of the DGCL, for liability for any breach of the director's duty of loyalty to the Registrant or its stockholders, for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law or for any transaction which the director derived an improper personal benefit.

ITEM 22. UNDERTAKINGS.

(1) That, for purposes of determining any liability under the Securities Act of 1933, each filing of the Registrant's Annual Report pursuant to Section 13(a) or Section 15(d) of the Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Exchange Act of 1934), that is incorporated by reference in the Registration Statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(2) That prior to any public reoffering of the securities registered hereunder through use of a prospectus which is a part of this registration statement, by any person or party who is deemed to be an underwriter within the meaning of Rule 145(c), the issuer undertakes that such reoffering prospectus will contain the information called for by the applicable registration form with respect to reofferings by persons who may be deemed underwriters, in addition to the information called for by the other items of the applicable form.

(3) That every prospectus: (i) that is filed pursuant to paragraph (2) immediately preceding, or (ii) that purports to meet the requirements of Section 10(a)(3) of the Act and is used in connection with an offering of securities subject to Rule 415, will be filed as a part of an amendment to the registration statement and will not be used until such amendment is effective, and that, for purposes of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(4) To respond to requests for information that is incorporated by reference into the prospectus pursuant to Item 4, 10(b), 11 or 13 of this form, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means. This includes information contained in documents filed subsequent to the effective date of the registration statement through the date of responding to the request.

(5) To supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the registration statement when it became effective.

(6) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to the provisions referred to in Item 15 (other than the insurance policies referred to therein), or otherwise, the Registrant has been advised that, in the opinion of the Securities and Exchange Commission, such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted against the Registrant by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

Such definition shall also apply to the terms "controlling," "controlled by" and "under common control with."

(3) Effective Date Tier Entity. Any Person that, as of the Article VIII Effective Date or the date that shares of Common Stock are issued pursuant to the Asset Purchase Agreement (as defined in B.5 below) after giving effect to such issuance, was a First Tier Entity or a Higher Tier Entity, for so long as such person continues to have a Prohibited Ownership Percentage.

(4) Expiration Date. The last day of the fifteen-year period commencing on the Article VIII Effective Date.

(5) First Tier Entity. A "first tier entity" with respect to the Corporation, as that term is defined in Treasury Regulations Section 1.382-2T(f)(9).

An increase of 47 percentage points or more of the Stock owned by "5-percent shareholders" of the Corporation (as defined in A(13) below) over the lowest percentage of Stock owned by such 5-percent shareholders at any time during the three-year period preceding any determination date, such determination to be made in accordance with Treasury Regulations Section 1.382-2T(c) as if the determination date were a "testing date."

(7) Higher Tier Entity. An "higher tier entity" with respect to the Corporation, as that term is defined in Treasury Regulations Section 1.382-2T(f)(14).

(8) Internal Revenue Code. The Internal Revenue Code of 1986, as amended. Any reference to a particular Section or provision of the Internal Revenue Code shall be deemed to also refer to any successor

(9) Ownership Change. An "ownership change" with respect to the Corporation, as that term is used in Section 382(g) of the Internal Revenue Code and Treasury Regulations Section 1.382-2T(a)(1), except that for purposes of determining whether 5-percent shareholders have increased their percentage interests by more than 50 percentage points, there shall be added to the increase in their percentage interests an amount equal to 2.5% of the total value of the Stock of the Corporation.

(10) Other Permitted Holders. Any Person, other than an Effective Date Tier Entity or a Permitted Transferee, which has a Prohibited Ownership Percentage permitted under Section 1, whether pursuant to a waiver under Paragraph D of Section 1 or otherwise.

(12) Person. Any individual, corporation, estate, trust, association, company, partnership, joint venture, or similar organization, or any other entity described in Treasury Regulations Section 1.382-3(a)(1)(i).

3

Treasury Regulations Section 1.382-2T(g)(1)(i) or (ii). For this purpose, whether a Person or Public Group would be a "5-percent shareholder" shall be determined (u) by substituting "4.5 percent" for "5 percent" each place it appears in such provisions, (v) without giving effect to the following provisions: Treasury Regulations Sections 1.382-2T(g)(2), 1.382-2T(g)(3), 1.382-2T(h)(2)(iii) and 1.382-2T(h)(6)(iii), (w) by treating every Person or Public Group which owns Stock, whether directly or by attribution, as directly owning such Stock notwithstanding any further attribution of such Stock to other Persons and notwithstanding Treasury Regulations Section 1.382-2T(h)(2)(i)(A), (x) by substituting the term "Person" in place of "individual" in Treasury Regulations Section 1.382-2T(g)(1)(i), (y) by taking into account ownership of Stock at any time during the "testing period" as defined in Treasury Regulations Section 1.382-2T(d)(1), and (z) by treating each day during the testing period as if it were a "testing date" as defined in Treasury Regulations Section 1.382-2T(a)(2)(i).

(14) Public Group. A "public group" with respect to the Corporation, as that term is used in Treasury Regulations Section 1.382-2T(f)(13), excluding any "direct public group" with respect to the Corporation, as that term is used in Treasury Regulations Section 1.382-2T(j)(2)(ii).

(15) Stock. All classes of stock of the Corporation, all options to acquire stock of the Corporation and all other interests that would be treated as stock in the Corporation pursuant to Treasury Regulations
Section 1.382-2T(f)(18)(iii), other than (x) stock described in Section 1504(a)(4) of the Internal Revenue Code and (y) stock that would be described in such Section 1504(a)(4) but is not so described solely because it is entitled to vote as a result of dividend arrearages. As used in this Article VIII, the term "option" shall have the meaning set forth in Treasury Regulations Section 1.382-2T(h)(4).

(16) Tax Benefits. The net operating loss carryovers and capital loss carryovers to which the Corporation is entitled under the Internal Revenue Code, free of restrictions under Section 382 of the Internal Revenue Code.

Any Transfer or acquisition of Stock or any other action (including the acquisition or issuance of an option to Transfer or acquire Stock), if the effect of such Transfer, acquisition or other action would be to cause a "testing date" with respect to the Corporation within the meaning of Treasury Regulations Section 1.382-2T(a)(2)(i), determined by treating every Person and Public Group which has a Prohibited Ownership percentage as a 5-percent shareholder as used in such Section.

(18) Transfer. Any means of conveyance of legal or beneficial ownership of Stock, whether such ownership is direct or indirect, voluntary or involuntary, including, without limitation, an indirect transfer of ownership through the transfer of any ownership interest of any entity that owns Stock.

(19) Transferee Undertaking. A duly executed written undertaking for the benefit of the Corporation by any transferee pursuant to which the transferee agrees that (i) it will not take any of the following actions without the prior consent of the Board of Directors (x) acquire any additional Stock, (y) Transfer any Stock in violation of Paragraph B of
Section 1, or (z) take or cause to be taken any Testing Date Action, (ii) upon request by the Corporation, it will furnish or cause to be furnished to the Corporation all certificates representing Stock held of record or beneficially, directly or indirectly, by it or by any Person controlling, controlled by or under common control with it for the purpose of placing a legend on such certificates to reflect the undertakings described in clause (i) above, (iii) it acknowledges that stop transfer orders may be entered with the transfer agent (or agents) and the registrar (or registrars) of Stock against the transfer of Stock subject to the undertakings described in clause (i) above except in compliance with the requirements of such undertakings, and (iv) it will agree to such other actions and remedies as the Corporation may reasonably request in order to preserve the Tax Benefits.

4

(20) Treasury Regulations. The regulations promulgated by the Secretary of the Treasury under the Internal Revenue Code. Any reference to a particular Treasury Regulation or Section or provision thereof shall be deemed to also refer to any successor Regulation or Section or provision having similar effect.

B. Transfer Restrictions.

Unless otherwise consented to or waived by the Board of Directors, the following Transfers and actions shall be prohibited:

(1) General. No Person shall Transfer any Stock to any other Person to the extent that such Transfer, if effected, (i) would cause the transferee or any person or Public Group to have a Prohibited Ownership Percentage, or (ii) would increase the ownership percentage of any transferee or any Person or Public Group having a Prohibited Ownership Percentage.

(2) Additional Restrictions on Transfers Involving Effective Date Tier Entities. In addition to the restrictions under Subparagraph B(1),
(i) no Effective Date Tier Entity or individual that owns a direct ownership interest in the Corporation of five percent or more shall Transfer any Stock, and no other Person shall Transfer any Stock to an Effective Date Tier Entity, if, in either case, after such Transfer, there would be a 47 Percentage Point Increase, and (ii) no Effective Date Tier Entity or individual that owns a direct ownership interest in the Corporation of five percent or more shall take any other action (including the acquisition or issuance of an option to Transfer or acquire Stock) if, after such action, there would be a 47 Percentage Point Increase.

(3) Additional Restrictions on Transfers Involving Other Permitted Holders. In addition to the restrictions under Subparagraph B(1), (i) no Other Permitted Holder shall Transfer any Stock, and no other Person shall Transfer any Stock to an Other Permitted Holder, if, in either case, such Transfer would constitute a Testing Date Action, and (ii) no Other Permitted Holder shall take any other action that would constitute a Testing Date Action.

(4) Additional Restrictions under Transferee Undertakings. In addition to the restrictions under Subparagraph B(1), (i) no Person who has delivered a Transferee Undertaking shall Transfer any Stock, and no Person shall Transfer any Stock to any Person who has delivered a Transferee Undertaking, if, in either case, such Transfer would result in a violation of such Transferee Undertaking, and (ii) no Person who has delivered a Transferee Undertaking shall take or cause to be taken any other action that would constitute a Testing Date Action.

(5) Exception. Notwithstanding anything herein to the contrary, the issuance of shares of Common Stock of the Corporation to Navistar International Transportation Corp. ("Navistar") or its designees pursuant to the terms of an Asset Purchase Agreement, dated September 12, 1996 (the "Asset Purchase Agreement"), between Navistar and RYMAC Mortgage Investment Corporation shall not be deemed to be a violation of the transfer restrictions set forth in this Paragraph B.

C. Permitted Transfers.

(1) General. Unless otherwise restricted under Paragraph B of Section 1 or under a Transferee Undertaking or other agreement, Transfers of Stock may be made without the consent of the Board of Directors.

(2) Transfers by Effective Date Tier Entities. Upon petition by any Effective Date Tier Entity or individual that owns a direct ownership interest in the Corporation of five percent or more, the Board of Directors shall consent to a proposed Transfer of Stock that complies with Subparagraph B(2) of Section 1 but would otherwise be prohibited pursuant to Subparagraph B(1) of Section 1 if it determines that (i) after giving effect to such Transfer, the percentage of Stock owned by all Persons and Public Groups with a Prohibited Ownership percentage will not have increased by more than 47 percentage points over the lowest percentage of Stock owned by such Persons and Public Groups at any time during the three-year period preceding the proposed date of such Transfer (such determination to be made in accordance with the provisions of Treasury Regulations Section 1.382-2T(c)) and (ii) the proposed transferee shall have delivered a Transferee Undertaking.

5

(3) Transfers by Permitted Transferees. Upon petition by any Permitted Transferee, the Board of Directors shall consent to a proposed Transfer of Stock or Testing Date Action that would otherwise be prohibited pursuant to Subparagraph B(1) or B(4) of Section 1 or pursuant to any Transferee Undertaking if it determines that (i) after such proposed Transfer or Testing Date Action there would not be an Ownership Change and (ii) in the case of any such proposed Transfer that, if effected, would otherwise be prohibited under Subparagraph B(1) of Section 1, such Transfer would otherwise be permitted under Subparagraph C(2) if such Transfer were proposed to be made by an Effective Date Tier Entity.

(4) Certain Additional Transfers to Permitted Transferees. Upon petition by any Permitted Transferee, the Board of Directors shall consent to a proposed Transfer of additional Stock to such Permitted Transferee from a Person constituting an Effective Date Tier Entity or another Permitted Transferee if it determines that such proposed Transfer would otherwise be permitted under Subparagraph C(2) or C(3) of Section I, as the case may be.

(5) Transfers by Other Permitted Holders. Upon petition by any Other Permitted Holder, the Board of Directors shall consent to a proposed Transfer of Stock or Testing Date Action that would otherwise be prohibited pursuant to Subparagraph B(1), B(3) or B(4) of Section 1 or pursuant to any Transferee Undertaking if it determines that (i) after such proposed Transfer or Testing Date Action there would not be an Ownership Change and (ii) in the case of any such proposed Transfer that, if effected, would otherwise be prohibited under Subparagraph (B)(1) of
Section 1, such Transfer would not cause a 47 Percentage Point Increase and the proposed transferee shall have delivered a Transferee Undertaking.

D. Waivers. Notwithstanding anything herein to the contrary, the Board of Directors may waive any of the restrictions contained in Paragraph B of Section 1 of this Article VIII: (a) in the case of any issuance of Stock by the Corporation which would otherwise be prohibited under Subparagraph B(1) of
Section 1, if the transferee agrees to be bound to the restrictions applicable to Permitted Transferees; (b) in the event of a tender or exchange offer within the meaning of the Securities Exchange Act of 1934, as amended, to acquire Stock constituting more than fifty percent in value of the outstanding Common Stock of the Corporation, so long as such waiver shall apply to all Transfers pursuant to such tender or exchange offer; (c) in connection with any Transfers of Stock in connection with underwritten offerings of such Stock; (d) in connection with any investment in or acquisition of a business or any business combination involving the Corporation or any subsidiary of the Corporation; and
(e) in any other instance in which the Board of Directors reasonably and in good faith determines that a waiver would be in the best interests of the Corporation.

SECTION 2. Attempted Transfer in Violation of Transfer Restrictions. Unless the consent or waiver of the Board of Directors is obtained as provided in Paragraph C or D of Section 1, and except as provided in Paragraph C of
Section 2 below, any attempted Transfer of shares of Stock of the Corporation in excess of the shares that could be Transferred to the transferee without restriction under Paragraph B of Section 1 is not effective to transfer ownership of such excess shares (the "Prohibited Shares") to the purported acquiror thereof (the "Purported Acquiror"), and the Purported Acquiror shall not be entitled to any rights as a shareholder of the Corporation with respect to the Prohibited Shares, including, without limitation, the right to vote or to receive dividends with respect thereto. Nothing contained in this Article VIII shall preclude the settlement of any transaction involving Stock entered into through the facilities of any national securities exchange on which the shares of Stock of the Corporation are listed. The application of the provisions and remedies described in the first sentence of this Section 2 and in Paragraphs A, B and C of Section 2 below shall be deemed not to so preclude any such settlement. Paragraphs A, B and C below shall apply only in the case of violations of the restrictions contained in Subparagraph B(1) of Section 1.

A. Transfer of Certificates; Sale of Stock. Upon demand by the Corporation, the Purported Acquiror shall transfer any certificate or other evidence of purported ownership of the Prohibited Shares within the Purported Acquiror's possession or control, together with any dividends or other distributions paid by the Corporation with respect to the Prohibited Shares that were received by the Purported Acquiror (the "Prohibited Distributions"), to an agent to be designated by the Corporation (the "Agent"). If the Purported Acquiror has sold the Prohibited Shares to an unrelated party in an arms-length transaction after purportedly acquiring them, the Purported Acquiror shall be deemed to have sold the Prohibited Shares for the Agent, and

6

in lieu of transferring the Prohibited Shares and Prohibited Distributions to the Agent shall transfer to the Agent the Prohibited Distributions and the proceeds of such sale (the "Resale Proceeds") except to the extent that the Agent grants written permission to the Purported Acquiror to retain a portion of the Resale Proceeds not exceeding the amount that would have been payable by the Agent to the Purported Acquiror pursuant to Paragraph B of Section 2 if the Prohibited Shares had been sold by the Agent rather than by the Purported Acquiror. Any purported Transfer of the Prohibited Shares by the Purported Acquiror, other than a transfer described in one of the two preceding sentences (unless such transfer itself violated the provisions of Article VIII), shall not be effective to transfer any ownership of the Prohibited Shares.

B. Allocation and Distribution of Proceeds. The Agent shall sell in an arms-length transaction (through the American Stock Exchange, if possible) any Prohibited Shares transferred to the Agent by the Purported Acquiror, and the proceeds of such sale (the "Sales Proceeds"), or the Resale Proceeds, if applicable, shall be allocated to the Purported Acquiror up to the following amount: (1) where applicable, the purported purchase price paid or value of consideration surrendered by the Purported Acquiror for the Prohibited Shares and (2) where the purported Transfer of the Prohibited Shares to the Purported Acquiror was by gift, inheritance, or any similar purported transfer, the fair market value of the Prohibited Shares at the time of such purported Transfer. Any Resale Proceeds or Sales Proceeds in excess of the amount allocable to the Purported Acquiror pursuant to the preceding sentence, together with any Prohibited Distributions (such excess amount and Prohibited Distributions are collectively the "Subject Amounts"), shall be transferred to an entity designated by the Corporation that is described in Section 501(c)(3) of the Internal Revenue Code (the "Designated Charity"). In no event shall any such Prohibited Shares or Subject Amounts inure to the benefit of the Corporation or the Agent, but such Subject Amounts may be used to cover expenses incurred by the Agent in performing its duties.

C. Limitation on Enforceability. Notwithstanding anything herein to the contrary, with respect to any Transfer of Stock which would cause a Person or Public Group (the "Prohibited Party") to violate a restriction provided for in Subparagraph B(1) of Section I only on account of the attribution to the Prohibited Party of the ownership of Stock by a Person or Public Group which is not controlling, controlled by or under common control with the Prohibited Party, which ownership is nevertheless attributed to the Prohibited Party, Subparagraph B(1) of Section 1 shall not apply in a manner that would invalidate such Transfer. In such case, the Prohibited Party and any Persons controlling, controlled by or under common control with the Prohibited Party (collectively, the "Prohibited Party Group") shall automatically be deemed to have disposed of, and shall be required to dispose of, sufficient shares of Stock (which shares shall consist only of shares held legally or beneficially, whether directly or indirectly, by any member of the Prohibited Party Group, but not shares held through another Person, other than shares held through a Person acting as agent or fiduciary for any member of the Prohibited Party Group, and which shares shall be disposed of in the inverse order in which they were acquired by members of the Prohibited Party Group) to cause the Prohibited Party, following such disposition, not to be in violation of Subparagraph B(1) of Section 1; provided that in the event no member of the Prohibited Party Group (i) is an Effective Date Tier Entity, Permitted Transferee or Other Permitted Holder and (ii) had any actual knowledge that such Transfer was prohibited under Subparagraph B(1) of Section 1, such disposition shall only be effected to the extent necessary in order to prevent an Ownership Change. Such disposition shall be deemed to occur simultaneously with the Transfer giving rise to the application of this provision, and such number of shares which are deemed to be disposed of shall be considered Prohibited Shares and shall be disposed of through the Agent as provided in Paragraph B of Section 2, except that the maximum amount payable to the Prohibited Party in connection with such sale shall be the fair market value of the prohibited Shares at the time of the Prohibited Transfer.

D. Other Remedies. In the event that the Board of Directors determines that a Person proposes to take any action in violation of Paragraph B of
Section 1, or in the event that the Board of Directors determines after the fact that an action has been taken in violation of Paragraph B of Section 1, the Board of Directors, subject to the second and third sentences of the introductory paragraph of Section 2, may take such action as it deems advisable to prevent or to refuse to give effect to any Transfer or other action which would result, or has resulted, in such violation, including, but not limited to, refusing to give effect to such Transfer or other action on the books of the Corporation or instituting proceedings to enjoin such Transfer or other action. If any Person shall knowingly violate Paragraph B of Section 1, then that Person and all other Persons controlling,

7

controlled by or under common control with such Person shall be jointly and severally liable for, and shall pay to the Corporation, such amount as will, after taking account of all taxes imposed with respect to the receipt or accrual of such amount and all costs incurred by the Corporation as a result of such loss, put the Corporation in the same financial position as it would have been in had such violation not occurred.

SECTION 3. Prompt Enforcement Against Purported Acquiror. Within 30 business days of learning of a purported Transfer of Prohibited Shares to a Purported Acquiror or a Transfer of Stock to a Prohibited Party, the Corporation through its Secretary or any Assistant Secretary shall demand that the Purported Acquiror or Prohibited Party surrender to the Agent the certificates representing the Prohibited Shares, or any Resale Proceeds, and any Prohibited Distributions, and if such surrender is not made by the Purported Acquiror or Prohibited Party within 30 business days from the date of such demand, the Corporation shall institute legal proceedings to compel such surrender; provided, however, that nothing in this Section 3 shall preclude the Corporation in its discretion from immediately bringing legal proceedings without a prior demand, and also provided that failure of the Corporation to act within the time periods set out in this Section 3 shall not constitute a waiver of any right of the Corporation to compel any transfer required by
Section 2. Upon a determination by the Board of Directors that there has been or is threatened a purported Transfer of Prohibited Shares to a Purported Acquiror or a Transfer of Stock to a Prohibited Party or any other violation of Paragraph B of Section 1, the Board of Directors may authorize such additional action as it deems advisable to give effect to the provisions of this Article VIII, including, without limitation, refusing to give effect on the books of the Corporation to any such purported Transfer or instituting proceedings to enjoin any such purported Transfer.

SECTION 4. Obligation to Provide Information. The Corporation may require as a condition to the registration of the Transfer of any Stock that the proposed transferee furnish to the Corporation all information reasonably requested by the Corporation with respect to all the direct or indirect ownership of Stock by the proposed transferee and by Persons controlling, controlled by or under common control with the proposed transferee.

SECTION 5. Legends. All certificates evidencing Stock that is subject to the restrictions on transfer set forth in this Article VIII shall bear a conspicuous legend referencing such restrictions.

SECTION 6. Further Actions. Subject to the second and third sentences of the introductory paragraph of Section 2, nothing contained in this Article VIII shall limit the authority of the Board of Directors to take such other action to the extent permitted by law as it deems necessary or advisable to protect the Corporation and the interests of the holders of its securities in preserving the Tax Benefits. Without limiting the generality of the foregoing, in the event of a change in law (including applicable regulations) making one or more of the following actions necessary, in the case of actions described in clauses (B), (C) and (D) below, or desirable, in the case of actions described in clause (A) below, the Board of Directors may (A) accelerate the Expiration Date, (B) extend the Expiration Date, (C) conform any terms or numbers set forth in the transfer restrictions in Section 1 to make such terms consistent with the Internal Revenue Code and the Treasury Regulations following any changes therein to the extent necessary to preserve the Tax Benefits, or (D) conform the definitions of any terms set forth in this Article VIII to the definitions in effect following such change in law; provided that the Board of Directors shall determine in writing that such acceleration, extension, change or modification is reasonably necessary to preserve the Tax Benefits or that the continuation of these restrictions is no longer reasonably necessary for the preservation of the Tax Benefits, which determination shall be based upon an opinion of legal counsel to the Corporation and which determination shall be filed with the Secretary of the Corporation and mailed by the Secretary to all stockholders of the Corporation within ten days after the date of any such determination.

SECTION 7. Severability. If any provision of this Article VIII or the application of any such provision to any Person or under any circumstance shall be held invalid, illegal, or unenforceable in any respect by a court of competent jurisdiction, such invalidity, illegality or unenforceability shall not affect any other provision of this Article VIII.

8

MEETINGS OF STOCKHOLDERS

Section 1. Annual Meeting. The annual meeting of the holders of shares of such classes or series of stock as are entitled to notice thereof and to vote thereat pursuant to the provisions of the Certificate of Incorporation (hereinafter called the "Annual Meeting of Stockholders") for the purpose of electing directors and transacting such other business as may come before it shall be held in each year at such time, on such day and at such place, within or without the State of Delaware, as shall be designated by the Board of Directors.

If mailed, the notice shall be directed to the stockholder in a postage-prepaid envelope at his address as it appears on the stock books of the Corporation. Notice of each meeting of stockholders shall be in such form as is


approved by the Board of Directors and shall state the purpose or purposes for which the meeting is called, the date and time when and the place where it is to be held, and shall be delivered personally or mailed not more than sixty

Section 4. Waiver of Notice. Whenever notice is required to be given under any provision of law or of the Certificate of Incorporation or the By-Laws, a waiver thereof in writing or by facsimile, telegraph, cable or other form of recorded communication, signed by the person entitled to notice, whether before or after the time stated therein, shall be deemed equivalent to notice. Attendance of a person at a meeting of stockholders shall constitute a waiver of notice of such meeting, except when the person attends such meeting for the express purpose of objecting, at the beginning of the meeting, to the transaction of any business because the meeting is not lawfully called or convened. Neither the business to be transacted at, nor the purpose of, any meeting of stockholders need be specified in any waiver of notice unless so required by the Certificate of Incorporation.

Section 5. Organization. The Chairman of the Board shall act as chairman at all meetings of stockholders at which he is present, and as such chairman shall call such meetings of stockholders to order and preside thereat. If the Chairman of the Board shall be absent from any meeting of stockholders, the duties otherwise provided in this Section 5 of Article II to be performed by him at such meeting shall be performed at such meeting by the officer prescribed by Section 5 of Article V. The Secretary of the Corporation shall act as secretary at all meetings of the stockholders, but in his absence the chairman of the meeting may appoint any person present to act as secretary of the meeting.

Section 6. Stockholders Entitled to Vote. The Board of Directors may fix a date not more than sixty (60) days nor less than ten (10) days prior to the date of any meeting of stockholders as a record date for the determination of the stockholders entitled to notice of and to vote at such meeting and any adjournment thereof, and in such case such stockholders and only such stockholders as shall be stockholders of record on the date so fixed shall be entitled to notice of, and to vote at, such meeting and any adjournment thereof, notwithstanding any transfer of any stock on the books of the Corporation after any such record date fixed as aforesaid. The Secretary shall prepare and make or cause to be prepared and made, at least ten (10) days before every meeting of stockholders, a complete list of the stockholders entitled to vote at such meeting, arranged in alphabetical order and showing the address of each such stockholder and the number of shares registered in the name of each such stockholder. Such list shall be open to the examination of any stockholder, for any purpose germane to the meeting, during ordinary business hours, for a period of at least ten (10) days prior to the meeting, either at a place,

2

specified in the notice of the meeting, within the city where the meeting is to be held, or, if not so specified, at the place where the meeting is to be held. Such list shall be produced and kept at the time and place of the meeting during the whole time thereof, and subject to the inspection of any stockholder who may be present.

Section 7. Quorum and Adjournment. Except as otherwise provided by law or by the Certificate of Incorporation, the holders of a majority of the shares of stock entitled to vote at the meeting on any matter present in person or by proxy without regard to class or series shall constitute a quorum at any meetings of the stockholders with respect to such matter. In the absence of a quorum, the holders of a majority of such shares of stock present in person or by proxy may adjourn any meeting, from time to time until a quorum shall be present. At any such adjourned meeting at which a quorum may be present, any business may be transacted which might have been transacted at the meeting as originally called. No notice of any adjourned meeting need be given other than by announcement at the meeting that is being adjourned, provided that if the adjournment is for more than thirty (30) days, or if after the adjournment a new record date is fixed for the adjourned meeting, then a notice of the adjourned meeting shall be given to each stockholder of record entitled to vote at the meeting.

Section 8. Order of Business. The order of business at all meetings of stockholders shall be as determined by the chairman of the meeting or as is otherwise determined by the vote of the holders of a majority of the shares of stock present in person or by proxy and entitled to vote without regard to class or series at the meeting.

Section 9. Nominations. Subject to the rights of holders of any series of Preferred Stock or any other class of capital stock of the Corporation (other than the Common Stock) then outstanding, nominations for the election of directors may be made by the affirmative vote of a majority of the entire Board of Directors or by any stockholder of record entitled to vote generally in the election of directors. However, any stockholder of record entitled to vote generally in the election of directors may nominate one or more persons for election as directors at a meeting only if written notice of such stockholder's intent to make such nomination or nominations has been given, either by personal delivery or by United States mail, postage prepaid, to the Secretary of the Corporation not less than 50 days nor more than 75 days prior to the meeting; provided, that in the event that less than 60 days notice or prior public disclosure of the date of the meeting is given or made to stockholders, notice by the stockholder to be timely must be so received not later than the close of business on the 10th day following the day on which such notice of the date of meeting was mailed or such public disclosure was made, whichever first occurs. Each such notice to the Secretary shall set forth: (i) the name and address of record of the stockholder who intends to make the nomination; (ii) a representation that the stockholder is a holder of record of shares of the Corporation's capital stock entitled to vote at such meeting and intends to appear in person or by proxy at the meeting to nominate the person or persons specified in the notice; (iii) the name, age, business and residence addresses, and principal occupation or employment of each proposed nominee; (iv) a description of all

3

arrangements or understandings between the stockholder and each proposed nominee and any other person or persons (naming such person or persons) pursuant to which the nomination or nominations are to be made by the stockholder; (v) such other information regarding each proposed nominee as would be required to be included in a proxy statement filed pursuant to the proxy rules of the Securities and Exchange Commission; and (vi) the written consent of each proposed nominee to serve as a director of the Corporation if so elected. The Corporation may require any proposed nominee to furnish such other information as may reasonably be required by the Corporation to determine the eligibility of such proposed nominee to serve as a director of the Corporation. The presiding officer of the meeting may, if the facts warrant, determine that a nomination was not made in accordance with the foregoing procedure, and if he should so determine, he shall so declare to the meeting and the defective nomination shall be disregarded.

Section 10. Vote of Stockholders. Except as otherwise required by law or by the Certificate of Incorporation or by the By-Laws, all action by stockholders shall be taken at a stockholders' meeting. Every stockholder of record, as determined pursuant to Section 6 of this Article II, and who is entitled to vote, shall, except as otherwise expressly provided in the Certificate of Incorporation with respect to any class or series of the Corporation's capital stock, be entitled at every meeting of the stockholders to one vote for every share of stock standing in his name on the books of the Corporation. Every stockholder entitled to vote may authorize another person or persons to act for him by proxy duly appointed by an instrument in writing, subscribed by such stockholder and executed not more than three (3) years prior to the meeting, unless the instrument provides for a longer period. The attendance at any meeting of stockholders of a stockholder who may theretofore have given a proxy shall not have the effect of revoking such proxy unless such stockholder shall in writing so notify the secretary of the meeting prior to the voting of the proxy. Election of directors shall be by written ballot but, unless otherwise provided by law, no vote on any question upon which a vote of the stockholders may be taken need be by ballot unless the chairman of the meeting shall determine that it shall be by ballot. In a vote by ballot each ballot shall state the number of shares voted and the name of the stockholder or proxy voting. Except as otherwise provided in Sections 12 and 13 of Article III or by the Certificate of Incorporation, each director shall be elected by a plurality of the votes of the shares present in person or represented by proxy at the meeting and entitled to vote on the election of directors. Except as provided in the foregoing sentence and except as otherwise provided by law or by the Certificate of Incorporation, the affirmative vote of a majority of shares present in person or represented by proxy at the meeting and entitled to vote on the subject shall be the act of the stockholders.

Section 11. Shares Entitled to More or Less than One Vote. If any class or series of the Corporation's capital stock shall be entitled to more or less than one vote for any share, on any matter, every reference in the By-Laws to a majority or other proportion of stock shall refer to such majority or other proportion of the votes of such stock.

INDEMNIFICATION

Section 1. The Corporation shall indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the Corporation) by reason of the fact that such person is or was a director or officer of the Corporation, or is or was serving at the request of the Corporation as a director, officer, member, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding if such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the Corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe such person's conduct was unlawful. The termination of any action, suit or proceeding by judgment, order, settlement, conviction, or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption that the person did not act in good faith and in a manner which such person reasonably believed to be in or not opposed to the best interest of the Corporation, and, with respect to any criminal action or proceeding, had reasonable cause to believe that such person's conduct was unlawful.

Section 2. The Corporation shall indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the Corporation to procure a judgment in its favor by reason of the fact that such person is or was a director or officer of the Corporation, or is or was serving at the request of the Corporation as a director, officer or member of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys' fees) actually and reasonably incurred by such person in connection with the defense or settlement of such action or suit if such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the Corporation, except that no such indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the Corporation unless and only to the extent that the Court of Chancery of Delaware or the court in which such suit or action was brought shall determine upon application that, despite the adjudication of liability but in consideration of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which such court shall deem proper.

14

Section 3. The Corporation may, to the extent deemed advisable by the Board of Directors, indemnify any person who is or was an employee or agent (other than a director or officer) of the Corporation if such person would be entitled to such indemnity under the provisions of Section 1 or 2 if such person had been a director or officer of the Corporation.

Section 4. To the extent that a person shall be successful on the merits or otherwise in defense of any action, suit or proceeding referred to in Sections 1, 2 or 3 or in defense of any claim, issue or matter therein, such person shall be indemnified against expenses (including attorneys' fees) actually and reasonably incurred by such person in connection therewith.

Section 5. Any indemnification under Sections 1, 2 or 3 (unless ordered by a court) shall be made by the Corporation only as authorized in the specific case upon a determination that indemnification of the director, officer, member, employee or agent is proper in the circumstances because such person has met the applicable standard of conduct set forth in Sections 1 and 2. Such determination shall be made (1) by a majority vote of the directors who are not parties to such action, suit or proceeding, even though less than a quorum, or
(2) if there are no such directors, or if such directors so direct, by independent legal counsel in a written opinion, or (3) by the stockholders.

Section 6. Expenses (including attorneys' fees) incurred by an officer or director in defending any civil, criminal, administrative or investigative action, suit or proceeding shall be paid by the Corporation in advance of the final disposition of such action, suit or proceeding upon receipt of an undertaking by or on behalf of the director or officer to repay such amount if it shall ultimately be determined that such person is not entitled to be indemnified by the Corporation as authorized in this Article VIII. Such expenses (including attorneys' fees) incurred by other employees and agents may be so paid upon such terms and conditions, if any, as the Board of Directors deems appropriate.

Section 7. The indemnification and advancement of expenses provided by, or granted pursuant to, this Article VIII shall not be deemed exclusive of any other rights to which those seeking indemnification or advancement of expenses may be entitled under any statute, By-Law, agreement, vote of stockholders or disinterested directors or otherwise, both as to action in such person's official capacity and as to action in another capacity while holding such office, and shall, unless otherwise provided when authorized or ratified, continue as to a person who has ceased to be a director, officer, member, employee or agent and shall inure to the benefit of the heirs, executors, and administrators of such person.

Section 8. The Corporation shall have the power to purchase and maintain insurance on behalf of any person who was or is a director, officer, employee or agent of the Corporation, or is or was serving at the request of the Corporation as a director, officer, member, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against any liability asserted against such person and incurred by such person in any such capacity, or arising

15

out of such person's status as such, whether or not the Corporation would have the power to indemnify such person against such liability under the provisions of this Article VIII or of the General Corporation Law of the State of Delaware.

Section 10. For the purposes of this Article VIII, references to "the Corporation" shall include, in addition to the resulting corporation, any constituent corporation (including any constituent of a constituent) absorbed in a consolidation or merger and the Corporation which, if its separate existence had continued, would have had power and authority to (or in fact did) indemnify its directors, officers, employees or agents, so that any person who is or was a director, officer, employee or agent of such constituent corporation, or is or was serving at the request of such constituent corporation as a director, officer, member, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, shall stand in the same position under the provisions of this Article with respect to the resulting or surviving corporation as such person would have with respect to such constituent corporation if its separate existence had continued.

Section 11.

Re: Core Materials Corporation Registration Statement on Form S-4

Dear Sir or Madam:

We have acted as counsel to Core Materials Corporation, a Delaware corporation (the "Company"), in connection with the preparation and filing of a registration statement on Form S-4, which was filed with the Securities and Exchange Commission on November 8, 1996 (the "Registration Statement").

The Registration Statement covers 9,734,600 shares of Common Stock of the Company, par value $0.01 per share (the "Common Stock"), which number includes (1) 5,210,600 shares of Common Stock issuable in the merger of the Company with RYMAC Mortgage Investment Corporation, a Maryland corporation ("RYMAC"), to existing holders of the common stock of RYMAC, (2) 4,264,000 shares of Common Stock issuable to Navistar International Transportation Corp. ("Navistar") pursuant to the Asset Purchase Agreement between RYMAC and Navistar dated as of September 12, 1996 and as amended on October 31, 1996 (as so amended, the "Asset Purchase Agreement") (such shares of Common Stock referred to in clauses (1) and (2) of this paragraph are referred to as the "Transaction Shares"), and (3) 260,000 shares issuable upon the exercise of outstanding options (the "Option Shares").

We have examined the Registration Statement, including the Exhibits thereto, the Company's Certificate of Incorporation as amended, the Company's By-laws, and related minutes of actions taken by the Board of Directors of the Company. In the foregoing examination, we have assumed the genuineness of all signatures, the authenticity of all documents submitted to us as originals


and the conformity to original documents of all documents submitted to us as certified, conformed or photostatic copies.

Based upon the foregoing, we are of the opinion that the Transaction Shares, when issued in accordance with and as contemplated by the terms of the Asset Purchase Agreement, and the Option Shares, when issued upon the exercise of outstanding options against payment of the consideration therefor, will be validly issued, fully paid and non-assessable.

We hereby consent to the filing of this opinion as Exhibit 5 to the Registration Statement. We also consent to the reference to this firm under the heading "Legal Matters" in the Proxy Statement and Prospectus constituting a part of the Registration Statement.

Very truly yours,

FOR VALUE RECEIVED, Rymac Mortgage Investment Corporation, a Maryland corporation (the "Company"), hereby promises to pay to the order of Navistar International Transportation Corp., a Delaware corporation ("Navistar"), the principal amount of $____ (or the unpaid principal amount from time to time outstanding hereunder) together with interest thereon calculated from the date hereof in accordance with the provisions of this Note.

This Note was issued pursuant to that certain Asset Purchase Agreement, dated as of September___, 1996 (as amended and modified from time to time, the "Purchase Agreement"), between the Company and Navistar. The Purchase Agreement contains certain terms governing the rights of the holder of this Note which are incorporated herein by reference. Except as defined in paragraph 10 hereof and unless otherwise indicated herein, capitalized terms used in this Note have the same meanings set forth in the Purchase Agreement. Notwithstanding anything to the contrary herein, it is expressly agreed that the outstanding principal amount of this Note may, from time to time, be increased pursuant to certain purchase price adjustments set forth in Section 1(g) of the Purchase Agreement (the "Purchase Price Adjustments").

1. Payments of Principal and Interest.

(a) Principal Payment. The Company shall pay principal installments under this Note to the Noteholder as follows:

(i) Within ninety (90) days after the end of each fiscal year of the Company during the term hereof, the Company shall pay principal in an amount equal to the amount, if any, by which the total cash and Cash Equivalents of the Company, as shown on the Company's audited balance sheet and statement of financial condition as of the end of such fiscal year, prepared in accordance with GAAP, exceeds Three Million Dollars ($3,000,000.00); and

(ii) In the event the Company obtains, from time to time, any Refinancing Loan, the Company shall promptly upon obtaining such loan pay principal in an amount equal to the proceeds of such loan.

If not sooner paid, the Company shall pay the entire principal amount of this Note then outstanding to the Noteholder in full on November___, 2006 (the "Maturity Date"), together with any and all accrued and unpaid interest and any other amounts due hereunder.


(b) Interest. Except as otherwise expressly provided herein, interest shall accrue at the rate of eight percent (8.0%) per annum, (computed on the basis of a 360-day year and the actual number of days elapsed in any year) on the unpaid principal amount of this Note outstanding from time to time from and including the date hereof until the date paid, or (if less) at the highest rate then permitted under applicable law. The Company shall pay to the Noteholder all accrued interest on the last business day of each May and November, beginning after the date hereof. Notwithstanding anything to the contrary contained herein, on the date any such scheduled interest payment becomes due the Company may elect to add such interest payment to the outstanding principal balance of the Note to be repaid with interest in accordance with the provisions of this Note; provided, that (i) the board of directors of the Company by resolution declares that the payment of such scheduled interest payment would be reasonably expected to significantly effect the Company's and any of its Subsidiaries' ability to fund current operations and (ii) the Noteholder shall have received written notice of such election at least thirty (30) days before the date of such scheduled interest payment, which notice shall be accompanied by a certified copy of the resolution of the board of directors of the Company referred to in clause (i) above and an amendment to this Note, in form and substance satisfactory to the Noteholder, duly executed by the Company and dated as of the date such scheduled interest payment becomes due, which amendment shall increase the principal amount of this Note by the amount of such scheduled interest payment. Payments received by the Noteholder from the Company on this Note shall be applied first to the payment of interest which is due and payable and only thereafter to the outstanding principal balance hereof. Unless prohibited under applicable law, any accrued interest which is not paid on the date on which it is due and payable shall bear interest at the same rate at which interest is then accruing on the principal amount of this Note until such interest is paid. Any accrued interest which for any reason has not theretofore been paid shall be paid in full on the date on which the final principal payment on this Note is made.

2. Prepayments; Setoff.

(a) Optional Prepayments. The Company may, without premium or penalty, at any time and from time to time, prepay all or any portion (in whole number multiples of $50,000) of the outstanding principal amount of this Note, provided that the Company has paid all interest on this Note accrued through the immediately preceding scheduled interest payment date. In connection with any prepayment of principal pursuant to this paragraph 2(a), the Company shall also pay all accrued and unpaid interest on the principal amount of this Note being prepaid. Any prepayment of less than all of the outstanding principal amount of this Note pursuant to this paragraph shall be applied to the scheduled payments of the outstanding principal amount of this Note in the inverse order of maturity.

(b) Right of Setoff. In addition to all other rights and remedies available to Navistar hereunder or otherwise, Navistar shall have the right, after the occurrence and during the continuance of any Default or Event of Default, to setoff against and to apply to the accrued and unpaid interest and outstanding principal balance of the Note (in each case, to the extent then due and payable), any obligation owing by Navistar to the Company. Any such setoff shall be applied first to the payment of interest which is due and payable and only thereafter to the outstanding principal balance hereof. A setoff of less than all of the outstanding principal amount of this Note shall be applied to the scheduled payments of the outstanding principal amount of this Note in the inverse order of maturity.

3. Collateral Security. This Note is secured by a first priority lien upon and security interest in all of the Company's assets, whether now owned or hereafter acquired, and is entitled to the benefits of the Security Documents. Notwithstanding the foregoing, Noteholder agrees that it will (if requested to do so by the holder of the Senior Obligations), upon terms reasonably acceptable to Noteholder, subordinate its security interest and lien in the Collateral (as defined in the Security Documents) in connection with and to the extent reasonably required to facilitate a Refinancing Loan, and promptly upon the request of the holder of the Senior Obligations, it will execute and deliver such documents, instruments and agreements as are necessary to evidence such subordination.

Buyer further agrees that the costs of replacement of said tooling, jigs and fixtures and associated equipment caused by normal use and age of these items will be the responsibility of the Buyer.

15. ELECTRONIC DATA INTERCHANGE (EDI) - SCHEDULES AND FORECASTS

A. Seller agrees to arrange to be in a position to communicate and receive all current and future EDI transactions deemed necessary by Buyer within twelve months of a consummated transaction.

B. The parties contemplate that Buyer will communicate production/service schedules and releases to Seller, and Seller shall confirm the same to Buyer as soon as practicable via electronic data interchange (EDI). EDI is the electronic exchange of routine business transactions (purchase orders, material releases, shipping authorizations, shipment notifications, etc.). On not less than a monthly basis, Buyer shall issue to Seller a set of communications via EDI. The EDI communications, among other things, shall define Buyer's requirements for production/service material as hereinafter provided.

C. Buyer's Scheduling and Release program will provide weekly regeneration of production requirements netted against current available inventory. The requirements horizon will be six (6) months, and will contain both customer orders and production forecasts. Furthermore, the six (6) month schedule horizon will contain current production requirements consisting of twenty (20) daily buckets, eight (8) weekly buckets, one
(1) balance-of-the-month bucket, and three (3) monthly buckets of production requirements. Buyer's liability for materials shall be limited to the requirements shown in the most current six (6) week schedule/release, which shall represent a firm commitment for Products, except as the parties otherwise agree in writing from time to time with regard to specific components which the parties acknowledge require additional lead time, and for which parts Buyer shall provide Seller with additional lead time in excess of such six (6) week firm schedule/release. The parties contemplate that the regenerated schedules will be transmitted weekly via the EDI 830 transaction set. In addition, the parties further contemplate that the requirements displayed in each new weekly schedule should match very closely to the daily requirements which will be transmitted via the EDI 862 Shipment Authorization. These schedules will be transmitted weekly unless an interim schedule change is required and agreed to in writing by the parties. Seller shall make arrangements to check its EDI mailbox on a daily basis.

D. Additional EDI transactions that will be transmitted weekly, or as required, shall include the EDI 856 Shipment Notification and EDI 997 Functional Acknowledgment.

16. VOLUMES

Seller and Buyer agree that volumes are based on past usage and projected market forecasts. No minimum quantities of annual production of Products or minimum purchase quantities are implied herein, and no penalties shall be imposed on Buyer for volumes of Products actually ordered by Buyer below those quantities forecasted.

17. INDEMNIFICATION

Seller indemnifies and holds harmless Buyer and its officers, directors and affiliates from any and all damages, costs and expenses incurred as a result of a claim by any third party regarding any harm, damage or loss incurred (or alleged to have incurred) as a direct result of any defect in the materials or workmanship of Seller's Products. Buyer indemnifies and holds harmless Seller and its officers, directors and affiliates from any and all damages, costs and expenses incurred as a result of a claim by any third party regarding any harm, damage, loss or expense incurred (or alleged to have incurred) as a result of Buyer's installation of Seller's Products other than as a direct result of any defect in the materials or workmanship of Seller's Products. If a claim is asserted against Buyer and Seller, Buyer and Seller shall reasonably cooperate in notifying the indemnifying party and shall permit the indemnifying party to conduct the defense of such claims at its option.

18. COMPETITIVE CLAUSE

In the spirit set forth in the recitals of this Agreement, the parties recognize that continuing to be competitive in price, performance, delivery, reliability, quality and technology is essential for this long-term association to exist. If Buyer reasonably demonstrates to Seller that the particular Product part number is not a competitive value in price, performance, delivery, reliability, technology and quality with other equivalent products of equivalent values, production, usage or availability in the world, then Seller agrees to provide an action plan and timetable within sixty (60) days of such demonstration to cure the deficiency. If the plan fails to cure the deficiency within the agreed upon timetable, then Buyer may at its option withdraw the non-competitive Product(s) from this Agreement and serve notice to terminate the obligations of the parties under this Agreement with respect thereto, effective upon the date specified by Buyer in such notice. Buyer agrees that prior to exercising its option, it will consider, in good faith, any proposal by Seller to correct the deficiency.

19. REIMBURSEMENT FOR NON-PERFORMANCE BY SELLER

A. Seller acknowledges that Buyer requires on-time delivery in order to operate its plants. The parties further acknowledge that the precise amount of damages which Buyer would sustain in the event Seller were to fail to make timely or conforming deliveries of Products would be difficult to determine. Therefore, the parties agree that Seller shall be responsible for consequential or incidental damages for the correction of products assembled out of sequence, as a result of delivery delays by Seller that are not due to circumstances beyond its control, such as weather, transportation system failures or other acts of God, or for the correction of products with quality problems by making a payment of $66 per manhour required to correct such problems.

6

Any costs Buyer incurs in connection with Buyer's assembly line down time caused by failure of Seller to deliver on schedule, for reasons not beyond its control but only to the extent that Buyer is not covered by business interruption insurance, will be charged at a rate of $700 per minute. Seller will advise Buyer immediately in writing of any apparent imminent problem and the parties will mutually use their best efforts to avoid any actual assembly line down time. Seller shall not be responsible for the above damages if such out-of-order (late) delivery or non-delivery results from a cause beyond Seller's reasonable control without fault or negligence, provided that Seller has immediately informed Buyer in writing of the problem. It is expressly understood that a failure by Seller to perform resulting from a strike, lockout or labor difficulty of Seller shall not be excused, and Seller shall be responsible for the above damages, except if Seller complies with Article 19-B below.

B. Seller shall promptly notify Buyer in writing of any anticipated labor dispute or labor shortage or any other labor performance interruption, and Seller shall arrange for advance deliveries or warehousing, at Buyer's option and at locations acceptable to Buyer, of a one month supply of Products, which Products shall be limited to those contained in the most current six week Scheduling Release (as described in Paragraph 15-C herein) or other quantity mutually agreed upon.

20. PRICING

A. Effective with shipments on January 1, 1998, all Product on contract will reflect a minimum [ * ] percent ([ * ]%) decrease on the non-raw material cost components. Furthermore, an additional minimum [ * ] percent ([ * ]%) price reduction on the non-raw material cost components will become effective on January 1 of each succeeding year for the duration of this Agreement.

B. Seller is required to provide to Buyer audited financial statements, including income statements, balance sheets and cash flow, on an annual basis.

21. MATERIAL, LABOR AND OVERHEAD

Labor and overhead costs will be firm, and only raw material adjustments will be made for the duration of this Agreement. Price adjustments for raw materials will be based on actual transaction prices and must be verified by actual sub-supplier invoices.

Documentation must be furnished by Seller in writing to Buyer to establish the starting base for future requested price adjustments. Seller will absorb [ * ] of any raw material price adjustment (increase or decrease). Buyer reserves the right to negotiate and/or purchase raw material from other sources for Seller that Buyer proves to be at a lower total cost. Material price adjustments will be subject to annual reviews. If a price adjustment is granted by Buyer, then a new price base for raw material will be established.

[ * ] = CONFIDENTIAL TREATMENT HAS BEEN REQUESTED

7

22. PRODUCT IMPROVEMENTS/COST REDUCTION

Seller and Buyer are committed to an active Product cost reduction program. Any Buyer-initiated cost savings resulting from Product improvements and/or design changes shall be credited [ * ] percent ([ * ]%) to Buyer. Mutually developed cost savings resulting from Product/process improvements and/or design changes shall be shared [ * ] with Buyer. Cost savings developed solely by Seller shall not affect contract prices.

23. CONFIDENTIAL INFORMATION

A. During the term of this Agreement, each party may disclose to the other certain confidential information relating to the Product(s), the application of the Product(s) by Buyer, and business information and marketing plans of either party. Any such information that is marked or otherwise clearly identified at the time of disclosure as "confidential" or "proprietary" shall be considered as Confidential Information for purposes of this Agreement, provided that, if the information is disclosed orally, a writing identified as "confidential" or "proprietary" and summarizing the Confidential Information will be provided within thirty (30) days after disclosure. During the term of this Agreement and for a period of five (5) years after the expiration or termination of this Agreement, the receiving party will use its best efforts to prevent its disclosure of such Confidential Information for any purpose other than to effectuate the provisions of this Agreement. "Best efforts" with respect to any Confidential Information means at least that degree of care normally used by the receiving party to prevent disclosure to others of its own confidential information of similar importance, but in no case less than a reasonable degree of care. Notwithstanding the foregoing, Seller and Buyer agree that Confidential Information shall not include any information which: (a) is or becomes publicly known through no wrongful act on the receiving party's part; or (b) is, at the time of disclosure under this Agreement, already known to the receiving party without restriction on disclosure; or (c) is, or subsequently becomes, rightfully and without breach of this Agreement, in the receiving party's possession without any obligation restricting disclosure; or (d) is independently developed by the receiving party without reference to or use of the Confidential Information; or (e) is disclosed pursuant to an order or requirement of any governmental or judicial authority, after prior notice to the disclosing party respecting such order, and affording the disclosing party reasonable cooperation respecting any objections by the disclosing party to the request for disclosure, including a reasonable opportunity for the disclosing party to obtain a protective order in respect of the Confidential Information at the expense of the disclosing party.

[ * ] = CONFIDENTIAL TREATMENT HAS BEEN REQUESTED

B. Upon request of the disclosing party at any time, the recipient agrees to return to the disclosing party or destroy all materials in its possession or control which contain Confidential Information of the disclosing party, including, without limitations, documents, drawings, CAD drawings, computer media, models, prototypes, sketches, designs, and lists furnished by the disclosing party or accessed by the recipient, including copies thereof made by the recipient, and to delete from its computers any software, data files, or CAD files containing Confidential Information furnished by the disclosing party. If materials are destroyed, an officer of the recipient shall identify such materials to the disclosing party and certify that their destruction has been completed. Notwithstanding the foregoing, each party shall be entitled to maintain one archival copy of the Confidential Information within its Law Department or at the office of its General Counsel, such archival copy to be used solely in connection with resolving claims or disputes between the parties relating to this Agreement.

C. This Article 23, Confidential Information, shall survive the termination or expiration of this Agreement.

24. PATENT, COPYRIGHT AND TRADE SECRET INDEMNITY

Seller agrees to defend, at its expense, any claim or suit against Buyer or Buyer's customers, based on an assertion or claim that a Product(s) furnished by Seller to Buyer hereunder or the use or sale by Buyer or its customers in the manner contemplated by this Agreement infringes any patent or copyright or is a wrongful use of third-party trade secret or proprietary information, and further agrees to indemnify and hold Buyer harmless from any cost and expenses, including attorneys' fees, settlements associated with said claim or suit, or any damages, including attorneys' fees or costs, finally awarded in any such suit, provided that Seller is notified promptly in writing of the suit or claim and, at Seller's request and expense, is given control of the defense to such claim or suit and all reasonable assistance for the defense of same. If the use or sale of a Product(s) furnished hereunder is enjoined as a result of such suit, Seller, at its option and at no expense to Buyer, shall obtain for Buyer and its customers the right to use and sell the Product(s) or shall substitute an equivalent Product(s) acceptable to Buyer and extend this indemnity thereto. This indemnity does not extend to any claim or suit based on any infringement of any patent by the combination of Product(s) furnished by Seller with other components added thereto by Buyer, except when the Product(s) is a material part of the invention of an asserted patent and the components furnished by Buyer to complete the claimed combination, such as an engine, sensor, or vehicle frame, are not novel. This indemnity does not extend to any infringement or alleged infringement arising solely out of Seller's compliance with Buyer-required specifications, designs, or instructions that (i) are created solely by Buyer and (ii) are thereafter furnished to Seller in writing.

9

25. TERMINATION

Any termination or expiration of all or part of this Agreement shall not relieve either party of obligations incurred pursuant to and during the terms of this Agreement, including but not limited to the warranty provisions set forth in Article 12 hereof, the indemnification provisions set forth in Article 17 hereof, and the "Confidential Information" provisions set forth in Article 23 hereof.

A. Termination for Default: At any time during the term of this Agreement should either party default in performing any of its material obligations hereunder, the other party may give written notice of default giving the full details thereof.

The non-defaulting party shall give the other party thirty (30) days written notice from the determination of the failure to cure the default, whereupon the termination shall be effective.

TRANSITIONAL SERVICES AGREEMENT

AGREEMENT, entered into and effective as of the _____ day of _______, 1996 (the "Effective Date"), by and between Navistar International Transportation Corp., a Delaware corporation, with its principal place of business at 455 North Cityfront Plaza Drive, Chicago, Illinois 60611, ("Provider"), and Rymac Mortgage Investment Corporation, a Delaware corporation, with its principal place of business at ___________________ __________________, ("Buyer") (Buyer and Provider are at times referred to herein individually as a "Party" and collectively as the "Parties").

WITNESSETH

WHEREAS, Provider and Buyer have entered into an Asset Purchase Agreement dated as of the date hereof (the "Purchase Agreement") pursuant to which Buyer agreed to purchase those certain assets of Provider's Columbus Plastics Division business as described in the Purchase Agreement (the "Plastics Business"); and

WHEREAS, as set forth in Paragraph ________ of the Purchase Agreement, Provider agreed to make available to Buyer certain transitional administrative and support services for the Plastics Business for a limited period after the completion of the sale in accordance with the terms of this Agreement.

NOW, THEREFORE, subject to the terms, conditions, covenants and provisions of this Agreement, Provider and Buyer mutually covenant and agree as follows:

ARTICLE 1.
SERVICES PROVIDED

1.1 TRANSITIONAL SERVICES. Upon the terms and subject to the conditions set forth in this Agreement, Provider will provide to Buyer for the Plastics Business each of those administrative and support services listed in APPENDIX A, which is attached to and made part of this Agreement (hereinafter referred to individually as a "Transitional Service", and collectively as the "Transitional Services"), during the time period for each Transitional Service set forth on APPENDIX A, (hereinafter referred to as the "Time Periods" for all of the Transitional Services, and the "Time Period" for each Transitional Service).

1.2 PERSONNEL. (a) In providing the Transitional Services, Provider, as it deems necessary or appropriate in its sole discretion, may (i) use such personnel of Provider or its affiliates, and (ii) employ the services of third parties to the extent such third party services are routinely utilized to provide similar services to other Provider businesses or are reasonably necessary for the efficient performance of any of such Transitional Services.


(b) Buyer agrees that Provider shall be entitled to use a reasonable amount of the services of those former employees of Provider, who were employed by Buyer as a result of the acquisition of the Plastics Business by Buyer, in the provision of the Transitional Services, which employees shall be made available by Buyer to Provider for this purpose.

1.3 LEVEL OF TRANSITIONAL SERVICES. (a) Nothing in this Agreement shall require Provider to favor the Plastics Business over its own businesses or those of any of its affiliates, subsidiaries or divisions. Provider shall devote such time and attention as are reasonably necessary to provide the Transitional Services required hereunder.

(b) Unless otherwise specifically set forth in the Appendixes attached hereto, it is the intention of the parties that Buyer's use of any Transitional Service that Buyer elects to use shall not be higher than the level of use required by the Plastics Business prior to the acquisition thereof by Buyer. In no event shall Buyer be entitled to any new service or to increase its use of any of the Transitional Services above that level of use without the prior written consent of Provider, which consent may be withheld by Provider for any or no reason in its sole and absolute discretion.

(c) As procedures, policies and services evolve and change with respect to its own operations, Provider reserves the right to make corresponding changes to the Transitional Services to be performed hereunder and to the procedures and policies used to provide and implement the Transitional Services. Provider shall not be required to provide Buyer extraordinary levels of Transitional Services, special studies, training, or the like or the advantage of systems, equipment, facilities, training, or improvements procured, obtained or made after the Effective Date by Provider.

1.4 LIMITATION OF LIABILITY AND WARRANTY. (a) In the absence of negligence or willful misconduct on Provider's part, Provider shall not be liable for any claims, liabilities, damages, losses, costs, expenses (including, but not limited to, settlements, judgments, court costs and reasonable attorneys' fees), fines and penalties, arising out of any actual or alleged injury, loss or damage of any nature whatsoever in providing or failing to provide the Transitional Services to Buyer. Notwithstanding anything to the contrary contained herein, in the event Provider commits an error with respect to or incorrectly performs or fails to perform any Transitional Service, at Buyer's request, Provider shall use reasonable efforts to correct such error, re-perform or perform such Transitional Service.

(b) In no event shall Provider be liable for any damages caused by Buyer's failure to perform Buyer's responsibilities hereunder unless Buyer's failure to perform is caused by Provider's negligence, willful misconduct or breach of this Agreement. Provider will not be liable to Buyer for any act or omission of any other entity (other than due to a default by Provider in any agreement between Provider and such other entity) furnishing any Transitional Service. Further, Provider will have no liability for lost, altered or destroyed data in providing any Transitional Service or for any interruption of any Transitional Services relating to computer or telecommunications services unless due to Provider's negligence or willful misconduct.

2

(c) NOTWITHSTANDING ANYTHING TO THE CONTRARY CONTAINED HEREIN OR AT LAW OR IN EQUITY, IN NO EVENT SHALL PROVIDER BE LIABLE FOR PUNITIVE, SPECIAL, INDIRECT, INCIDENTAL OR CONSEQUENTIAL DAMAGES (EXCLUDING, WITHOUT LIMITATION, DAMAGES FOR LOSS OF BUSINESS PROFITS, BUSINESS INTERRUPTION OR ANY OTHER LOSS) ARISING FROM OR RELATING TO ANY CLAIM MADE UNDER THIS AGREEMENT OR REGARDING THE PROVISION OF OR THE FAILURE TO PROVIDE THE TRANSITIONAL SERVICES, EVEN IF PROVIDER HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

1.5 NO OBLIGATION TO CONTINUE TO USE SERVICES. Buyer shall have no obligation to continue to use any of the Transitional Services and may delete any Transitional Service from the Transitional Services that Provider is providing to Buyer by giving Provider advance written notice of its desire to delete any or all Transitional Services; PROVIDED, that the deletion of any Transitional Service can only be effective on the last day of a calendar month. If any Transitional Service is deleted by Buyer, Provider shall have the option, in its sole and absolute discretion, to discontinue any related Transitional Services by providing written notice to Buyer.

1.6 TECHNOLOGY. Any processes, techniques, hardware, software, copyrights, patents, practices or other technical or proprietary matter related to, arising from, or used in connection with, the performance by Provider of the Transitional Services (the "Technology"), and any improvement, modification or new development in the Technology, shall be the sole and exclusive property of Provider.

1.7 PROVIDER ACCESS. To the extent reasonably required for Provider personnel to perform the Transitional Services, Buyer shall provide Provider personnel with access to its equipment, office space, plants, telecommunications and computer equipment and systems, and any other areas and equipment.

ARTICLE 2.
COMPENSATION

2.1 CONSIDERATION. As consideration for the Transitional Services, Buyer shall pay to Provider the amount specified for each Transitional Service as set forth in APPENDIX A. If the amount to be paid for any Transitional Service is described in APPENDIX A as "cost", the use of the term "cost" means the cost to Provider to provide that Transitional Service to Buyer. If the amount to be paid for any Service is described on APPENDIX A as "actual hours incurred", the amount of such fee shall be determined based on (i) all compensation costs for direct personnel of Provider who perform the Transitional Services (including, without limitation, payroll, overhead and related amounts), (ii) travel cost (including meals and lodging expenses) for such personnel and their successors incurred in connection with the Transitional Services, and (iii) other ordinary and necessary business expenses incurred by Provider in connection with the Transitional Services.

3

(b) In addition to the payments described in subparagraph (a) above, Buyer shall reimburse to Provider an amount equal to the sum of (i) all of the costs, if any, required by any third party incurred by Provider to obtain consents from such third parties to permit Provider to provide any Transitional Service to Buyer hereunder (including, without limitation, amounts paid for the right to continue to use third party software for the benefit of Buyer) ("Third Party Consent Costs"), plus (ii) any reasonable and customary expenditures made by Provider on behalf of Buyer pursuant to APPENDIX A to provide the Transitional Services to Buyer. Such costs and expenditures will be billed to Buyer in the monthly invoice(s) described in Paragraph 2.3 below. In the event that Provider will be making any such disbursements of funds on behalf of Buyer, before any disbursement will be made, Buyer shall, if requested by Provider, deposit funds equal to an estimated amount of such costs and expenditures into a bank account designated by Provider. Notwithstanding anything to the contrary in this subparagraph (b), all Third Party Consent Cost shall be subject to Buyer's prior approval; provided, however, that in the event Buyer does not approve such Third Party Consent Cost, Provider shall not be obligated under this Agreement to perform the Transitional Service to which such Third Party Consent Cost relates.

2.2 TAXES. Any taxes (other than income taxes) assessed against Provider on the provision of the Transitional Services shall be reimbursed by Buyer.

2.3 INVOICES. At the end of each month, each of Provider and its affiliates or subsidiaries providing the Transitional Services will submit one invoice to Buyer for (a) all Transitional Services provided to Buyer and its subsidiaries by such entity, and (b) those costs and expenditures described in Paragraph 2.1 (b) above incurred by such entity during such month. Such monthly invoices shall be issued no later than the fifteenth day of each month. Each invoice shall include documentation supporting each of the invoiced amounts. The total of this list and supporting detail will equal the invoice total, and will be provided under separate cover apart from the invoice. All invoices shall be sent to Buyer at the following address or to such other address as Buyer shall have specified by notice in writing to Provider:

If any failure or default so specified is not cured within such forty five (45) day period, the Non-Defaulting Party may elect to immediately terminate this Agreement; PROVIDED, HOWEVER, that if the failure or default relates to a dispute made in good faith by the Defaulting Party, the Non-Defaulting Party may not terminate this Agreement pending the resolution of such dispute. Such termination shall be effective upon giving a written notice of termination from the Non-Defaulting Party to the Defaulting Party and shall be without prejudice to any other remedy which may be available to the Non-Defaulting Party against the Defaulting Party.

6

(c) PROVIDER SHALL HAVE NO LIABILITY OF ANY KIND OR NATURE WHATSOEVER (INCLUDING, WITHOUT LIMITATION, INDIRECT, CONSEQUENTIAL, SPECIAL, INCIDENTAL OR PUNITIVE DAMAGES) TO BUYER, OR TO ANYONE CLAIMING BY OR THROUGH BUYER, FOR PROVIDER'S CEASING TO PROVIDE ANY TRANSITIONAL SERVICE UPON THE EXPIRATION OF THE TIME PERIOD FOR SUCH TRANSITIONAL SERVICE OR THE TERMINATION OF THIS AGREEMENT.

6.11 FORCE MAJEURE. Any failure or omission by Provider in the performance of any obligation under this Agreement on its part to be performed shall not be deemed a breach of this Agreement or create any liability, if the same arises from any cause or causes beyond the control of Provider, including, but not limited to, the following, which, for purposes of this Agreement shall be regarded as beyond the control of Provider: acts of God, fire, storm, flood, earthquake, governmental regulation or direction, acts of the public enemy, war, rebellion, insurrection riot, invasion, strike or lockout; PROVIDED, HOWEVER, that Provider shall resume the performance whenever such causes are removed.

EXHIBIT 10-D

REGISTRATION RIGHTS AGREEMENT

THIS AGREEMENT is made as of , 1996, by and among Rymac Mortgage Investment Corporation, a Delaware corporation (the "COMPANY"), Navistar International Transportation Corp., a Delaware corporation ("NAVISTAR") and each of the other Persons who becomes a party to this Agreement after the date hereof pursuant to paragraphs 10(e) or 10(f) below. Certain capitalized terms used herein are defined in paragraph 9 below.

WHEREAS, the Company and Navistar are parties to an Asset Purchase Agreement dated as of September , 1996 (the "PURCHASE AGREEMENT") pursuant to which Navistar has agreed to sell certain assets to the Company subject to the terms and conditions therein.

WHEREAS, as part of the consideration for the sale of certain of its assets, the Company is issuing to Navistar certain shares of the Company's Common Stock, par value $.01 per share (the "COMMON STOCK"); and

WHEREAS, the execution and delivery of this Agreement is a condition to Navistar's obligation to sell certain assets to the Company pursuant to the Purchase Agreement.

NOW, THEREFORE, in consideration of the mutual covenants contained herein and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties to this Agreement intending to be legally bound, hereby agree as follows:

The parties hereto agree as follows:

1. DEMAND REGISTRATIONS.

(a) REQUESTS FOR REGISTRATION. The holders of at least 20% of the Investor Registrable Securities may at any time request registration under the Securities Act of all or any portion of their Registrable Securities on Form S-1 or any similar long-form registration ("LONG-FORM REGISTRATIONS"), and the holders of at least 20% of the Investor Registrable Securities may request registration under the Securities Act of 1933, as amended (the "SECURITIES ACT") of all or any portion of their Registrable Securities on Form S-2 or S-3 (including pursuant to Rule 415 under the Securities Act) or any similar short-form registration ("SHORT-FORM REGISTRATIONS") if available. All registrations requested pursuant to this paragraph 1(a) are referred to herein as "DEMAND REGISTRATIONS". Each request for a Demand Registration shall specify the approximate number of Investor Registrable Securities requested to be registered and the anticipated per share price range for such offering. Within 10 days after receipt of any such request, the Company shall give written notice of such requested registration to all other holders of Registrable Securities and shall include in such registration all Registrable Securities with respect to which the Company has


received written requests for inclusion therein within 15 days after the receipt of the Company's notice.

(b) LONG-FORM REGISTRATIONS. The holders of Investor Registrable Securities shall be entitled to request 2 Long-Form Registrations. The Company shall pay all Registration Expenses for such Long-Form Registrations. Except as otherwise provided in this paragraph 1(b), (i) a registration shall not count as one of the permitted Long-Form Registrations until it has become effective and the holders of Investor Registrable Securities are able to register and sell at least 90% of the Investor Registrable Securities requested to be included in such registration; and (ii) the Company shall pay all Registration Expenses in connection with any registration initiated as a Long-Form Registration whether or not it has become effective and whether or not such registration has counted as one of the permitted Long-Form Registrations. The holders of Investor Registrable Securities may, before a Long-Form Registration becomes effective, withdraw their Registrable Securities from inclusion therein, should the terms of sale not be satisfactory to such holders. Should all such holders so withdraw, such Long-Form Registration shall be deemed to have been declared effective, unless such holders of Investor Registrable Securities pay within 30 days after any such withdrawal, their pro-rata share of all of the out-of-pocket expenses of the Company incurred in connection with such registration.

If so requested by the holders of at least a majority of the Investor Registrable Securities included in a Demand Registration, the public offering or distribution of Registrable Securities under this Agreement shall be pursuant to a firm commitment underwriting, the managing underwriter of which shall be a nationally recognized investment banking firm selected and engaged by the Company and approved by the holders of at least a majority of the Investor Registrable Securities included in such Demand Registration (which approval shall not be unreasonably withheld). The Company shall enter into the same underwriting agreement as entered into by the holders of Investor Registrable Securities, which shall contain representations, warranties, indemnities and agreements not substantially different from those customarily made by an issuer in underwriting agreements with respect to secondary distributions. The Company, as a condition to fulfilling its obligations under this Agreement, may require that such underwriting agreement contain customary provisions indemnifying the Company against any losses that arise out of or are based upon an untrue statement, an alleged untrue statement, an omission or an alleged omission in any registration statement or prospectus made in reliance upon and in conformity with written information furnished to the Company by the underwriters specifically for use in the preparation of such registration statement or prospectus.

(c) SHORT-FORM REGISTRATIONS. In addition to the Long-Form Registrations provided pursuant to paragraph 1(b), the holders of Investor Registrable Securities shall be entitled to request an unlimited number of Short-Form Registrations in which the Company shall pay all Registration Expenses. Demand Registrations shall be Short-Form Registrations whenever the Company is permitted to use any applicable short form. The Company shall use its best efforts to make Short-Form Registrations on Form S-3 available for the sale of Registrable Securities. If the Company, pursuant to the request of the holders of at least 20% of the Investor Registrable Securities, is qualified to and has filed with the Securities and Exchange Commission a registration statement under the Securities Act on Form S-3 pursuant to Rule 415 under the Securities Act (the

-2-

"REQUIRED REGISTRATION"), the Company shall use its best efforts to cause the Required Registration to be declared effective under the Securities Act as soon as practical after filing, and once effective, the Company shall cause such Required Registration to remain effective for a period ending on the earlier of
(i) the date on which all Registrable Securities have been sold pursuant to the Required Registration or (ii) the date as of which the holders of Investor Registrable Securities (assuming such holders are affiliates of the Company) are able to sell all of the Investor Registrable Securities then held by them within a ninety-day period in compliance with Rule 144 under the Securities Act (the "EFFECTIVE PERIOD"). The Company represents, warrants and covenants that it currently is, and shall remain at all times during the Effective Period, eligible to use Form S-2 under the Securities Act. Each party hereto hereby acknowledges that the Company is currently not eligible to effect a Required Registration for a primary offering, but is eligible to effect a Required Registration for a secondary offering.

(d) PRIORITY ON DEMAND REGISTRATIONS. The Company shall not include in any Demand Registration any securities which are not Registrable Securities without the prior written consent of the holders of at least 50% of the Investor Registrable Securities included in such registration. If a Demand Registration is an underwritten offering and the managing underwriter advises the Company in writing that in its opinion the number of Registrable Securities and, if permitted hereunder, other securities requested to be included in such offering exceeds the number of Registrable Securities and other securities, if any, which can be sold without adversely affecting the marketability of the offering, the Company shall include in such registration prior to the inclusion of any securities which are not Registrable Securities the number of Registrable Securities requested to be included which in the opinion of such underwriters can be sold without adversely affecting the marketability of the offering, first pro rata among the respective holders of the Investor Registrable Securities and then to the extent that any Other Registrable Securities can still be included, pro rata among the respective holders thereof on the basis of the amount of Registrable Securities owned by each such holder, and then to the extent that any securities which are not Registrable Securities can still be included, pro rata among the respective holders thereof on the basis of the amount of such securities owned by each such holder. Any Persons other than holders of Registrable Securities who participate in Demand Registrations which are not at the Company's expense must pay their share of the Registration Expenses as provided in paragraph 5 hereof.

(e) RESTRICTIONS ON DEMAND REGISTRATIONS. The Company shall not be obligated to effect any Demand Registration within 180 days after the effective date of a previous Demand Registration or a previous registration in which the holders of Registrable Securities were given piggyback rights pursuant to Section 2 and in which there was no reduction in the number of Registrable Securities requested to be included. The Company shall be entitled to postpone, for a reasonable period of time not in excess of 90 days after its receipt of an initial request for a Demand Registration pursuant to this Agreement, the filing of any registration statement if at the time it received a request therefor, the Company determines, in its reasonable business judgment, that such registration and offering could interfere with or otherwise adversely affect any financing, acquisition, corporate reorganization or other material transaction or development involving the Company or any of its subsidiaries or affiliates; provided that the Company shall only be entitled to one postponement in any 365-day period. The Company shall give the holders of Investor Registrable Securities making such request written notice of such determination. In the event of such postponement, the

-3-

Company shall file such Registration Statement as soon as practicable after it shall determine, in its reasonable business judgment, that such registration and offering will not interfere with the matters described in the first sentence of this Section 2(e) or, if later, at the end of such 90-day period. If the Company shall postpone the filing of any registration statement, the holders of Investor Registrable Securities shall have the right to withdraw their request for such registration by giving notice to the Company within 15 days of the notice of postponement; provided, however, that in the event that the holders of Investor Registrable Securities withdraw their request in the foregoing manner, such request shall not be counted for purposes of determining the number of registrations to which the holders of Investor Registrable Securities are entitled pursuant to paragraph (a) above.

Notwithstanding the provisions of this paragraph 1, the Company shall not be required to effect more than two Long-Form Registrations or more than five Demand Registrations that have been filed pursuant to paragraph 1(a) above, were declared effective by the Commission and remained effective for the period set forth in paragraph 4(b) hereof.

(f) OTHER REGISTRATION RIGHTS. Except as provided in this Agreement, the Company shall not grant to any Persons the right to request the Company to register any equity securities of the Company, or any securities convertible or exchangeable into or exercisable for such securities, without the prior written consent of the holders of at least 50% of the Investor Registrable Securities; provided that the Company may grant rights to employees of the Company and its Subsidiaries to participate in Piggyback Registrations so long as such rights are subordinate to the rights of the holders of Registrable Securities with respect to such Piggyback Registrations as provided in paragraphs 2(c) and 2(d) below.

2. PIGGYBACK REGISTRATIONS.

(a) RIGHT TO PIGGYBACK. Whenever the Company proposes to register any of its securities under the Securities Act (other than pursuant to a Demand Registration) and the registration form to be used may be used for the registration of Registrable Securities (a "PIGGYBACK REGISTRATION"), the Company shall give prompt written notice to all holders of Registrable Securities of its intention to effect such a registration and shall include in such registration all Registrable Securities with respect to which the Company has received written requests for inclusion therein within 15 days after the receipt of the Company's notice.

(b) PIGGYBACK EXPENSES. The Registration Expenses of the holders of Registrable Securities shall be paid by the Company in all Piggyback Registrations.

(c) PRIORITY ON PIGGYBACK REGISTRATIONS. If a Piggyback Registration is an underwritten primary registration on behalf of the Company, and the managing underwriters advise the Company in writing that in their opinion the number of securities requested to be included in such registration exceeds the number which can be sold without adversely affecting the marketability of the offering, the Company shall include in such registration
(i) first, the securities the Company proposes to sell, (ii) second, the Investor Registrable Securities requested to be included in such registration, pro rata among the holders of such Investor Registrable Securities on the basis of the number of shares owned by each such holder, (iii) third, the Other Registrable Securities requested

-4-

to be included in such registration, pro rata among the holders of such Registrable Securities on the basis of the number of shares owned by each such holder, and (iv) fourth, other securities requested to be included in such registration pro rata among the holders of such securities on the basis of the number of shares owned by each such holder.

(d) PRIORITY ON SECONDARY REGISTRATIONS. If a Piggyback Registration is an underwritten secondary registration on behalf of holders of the Company's securities, and the managing underwriters advise the Company in writing that in their opinion the number of securities requested to be included in such registration exceeds the number which can be sold without adversely affecting the marketability of the offering, the Company shall include in such registration (i) first, the securities requested to be included therein by the holders requesting such registration, (ii) second, the Investor Registrable Securities requested to be included in such registration, pro rata among the holders of such Investor Registrable Securities on the basis of the number of shares owned by each such holder, (iii) third, the Other Registrable Securities requested to be included in such registration, pro rata among the holders of such Registrable Securities on the basis of the number of shares owned by each such holder, and (iv) fourth, other securities requested to be included in such registration pro rata among the holders of such securities on the basis of the number of shares owned by each such holder.

(e) SELECTION OF UNDERWRITERS. If any Piggyback Registration is an underwritten offering, the selection of investment banker(s) and manager(s) for the offering must be approved by the holders of a majority of the Investor Registrable Securities included in such Piggyback Registration. Such approval shall not be unreasonably withheld or delayed.

(f) OTHER REGISTRATIONS. If the Company has previously filed a registration statement with respect to Registrable Securities pursuant to paragraph 1 or pursuant to this paragraph 2, and if such previous registration has not been withdrawn or abandoned, the Company shall not file or cause to be effected any other registration of any of its equity securities or securities convertible or exchangeable into or exercisable for its equity securities under the Securities Act (except on Form S-8 or any successor form), whether on its own behalf or at the request of any holder or holders of such securities, until a period of at least 180 days has elapsed from the effective date of such previous registration.

3. HOLDBACK AGREEMENTS.

(a) Each holder of Registrable Securities shall not effect any public sale or distribution (including sales pursuant to Rule 144) of equity securities of the Company, or any securities convertible into or exchangeable or exercisable for such securities, during the 10 days prior to and the 180-day period beginning on the effective date of any underwritten Demand Registration or any underwritten Piggyback Investor Registration in which Registrable Securities are included (except as part of such underwritten registration), unless the underwriters managing the registered public offering otherwise agree.

(b) The Company (i) shall not effect any public sale or distribution of its equity securities, or any securities convertible into or exchangeable or exercisable for such securities,

-5-

during the ten days prior to and during the 180-day period beginning on the effective date of any (x) underwritten Demand Registration, (y) underwritten Piggyback Registration (except as part of such underwritten registration or pursuant to registrations on Form S-8 or any successor form) or (z) post-effective amendment of a Required Registration pursuant to which an underwritten offering is to be effected, unless (in any such case) the underwriter managing the registered public offering otherwise agrees.

4. REGISTRATION PROCEDURES. Whenever the holders of Registrable Securities have requested that any Registrable Securities be registered pursuant to this Agreement, the Company shall use its best efforts to effect the registration and the sale of such Registrable Securities in accordance with the intended method of disposition thereof, and pursuant thereto the Company shall as expeditiously as possible:

(a) prepare and file with the Securities and Exchange Commission a registration statement with respect to such Registrable Securities and use its best efforts to cause such registration statement to become effective (provided that before filing a registration statement or prospectus or any amendments or supplements thereto, the Company shall furnish to the counsel selected by the holders of a majority of the Investor Registrable Securities covered by such registration statement copies of all such documents proposed to be filed, which documents shall be subject to the reasonable review and comment of such counsel);

(b) notify each holder of Registrable Securities of the effectiveness of each registration statement filed hereunder and prepare and file with the Securities and Exchange Commission such amendments and supplements to such registration statement and the prospectus used in connection therewith as may be necessary to keep such registration statement effective for a period of not less than 180 days or such longer period specified in paragraph 1(c) and comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such registration statement during such period in accordance with the intended methods of disposition by the sellers thereof set forth in such registration statement;

(c) furnish to each seller of Registrable Securities such number of copies of such registration statement, each amendment and supplement thereto, the prospectus included in such registration statement (including each preliminary prospectus) and such other documents as such seller may reasonably request in order to facilitate the disposition of the Registrable Securities owned by such seller;

(d) use its best efforts to register or qualify such Registrable Securities under such other securities or blue sky laws of such jurisdictions as any seller reasonably requests and do any and all other acts and things which may be reasonably necessary or advisable to enable such seller to consummate the disposition in such jurisdictions of the Registrable Securities owned by such seller (provided that the Company shall not be required to (i) qualify generally to do business in any jurisdiction where it would not otherwise be required to qualify but for this subparagraph, (ii) subject itself to taxation in any such jurisdiction or (iii) consent to general service of process in any such jurisdiction);

-6-

(e) notify each seller of such Registrable Securities, at any time when a prospectus relating thereto is required to be delivered under the Securities Act, of the happening of any event as a result of which the prospectus included in such registration statement contains an untrue statement of a material fact or omits any fact necessary to make the statements therein not misleading, and, at the request of any such seller, the Company shall prepare a supplement or amendment to such prospectus so that, as thereafter delivered to the purchasers of such Registrable Securities, such prospectus shall not contain an untrue statement of a material fact or omit to state any fact necessary to make the statements therein not misleading;

(f) cause all such Registrable Securities to be listed on each securities exchange on which similar securities issued by the Company are then listed;

(g) provide a transfer agent and registrar for all such Registrable Securities and a CUSIP number for all such Registrable Securities not later than the effective date of such registration statement;

(h) enter into such customary agreements (including underwriting agreements in customary form) and take all such other actions as the holders of a majority of the Registrable Securities being sold or the underwriters, if any, reasonably request in order to expedite or facilitate the disposition of such Registrable Securities (including effecting a stock split or a combination of shares);

(i) make available for inspection by any seller of Registrable Securities, any underwriter participating in any disposition pursuant to such registration statement and any attorney, accountant or other agent retained by any such seller or underwriter, all financial and other records, pertinent corporate documents and properties of the Company, and cause the Company's officers, directors, employees and independent accountants to supply all information reasonably requested by any such seller, underwriter, attorney, accountant or agent in connection with such registration statement, subject to the execution by any such person of a confidentiality agreement in form and substance reasonably satisfactory to the Company;

(j) otherwise use its best efforts to comply with all applicable rules and regulations of the Securities and Exchange Commission, and make available to its security holders, as soon as reasonably practicable, an earnings statement covering the period of at least twelve months beginning with the first day of the Company's first full calendar quarter after the effective date of the registration statement, which earnings statement shall satisfy the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder;

(k) permit any holder of Registrable Securities which holder, in its sole and exclusive judgment, might be deemed to be an underwriter or a controlling person of the Company, to participate in the preparation of such registration or comparable statement and to require the insertion therein of material, furnished to the Company in writing, which in the reasonable judgment of such holder and its counsel should be included;

-7-

(l) in the event of the issuance of any stop order suspending the effectiveness of a registration statement, or of any order suspending or preventing the use of any related prospectus or suspending the qualification of any common stock included in such registration statement for sale in any jurisdiction, use its best efforts promptly to obtain the withdrawal of such order;

(m) use its best efforts to cause such Registrable Securities covered by such registration statement to be registered with or approved by such other governmental agencies or authorities as may be necessary to enable the sellers thereof to consummate the disposition of such Registrable Securities;

(n) obtain a cold comfort letter from the Company's independent public accountants in customary form and covering such matters of the type customarily covered by cold comfort letters as the holders of a majority of the Investor Registrable Securities being sold reasonably request (provided that such Investor Registrable Securities constitute at least 10% of the securities covered by such registration statement); and

(o) use reasonable efforts to cause certificates for the Registrable Securities covered by such registration statement to be delivered by the holders thereof to the underwriters in such denominations and registered in such names as the underwriters may request.

5. REGISTRATION EXPENSES.

(a) Subject to paragraph (b) below, all expenses incident to the Company's performance of or compliance with this Agreement, including without limitation all registration and filing fees, fees and expenses of compliance with securities or blue sky laws, printing expenses, messenger and delivery expenses, fees and disbursements of custodians, fees and disbursements of counsel for the Company and fees and disbursements of all independent certified public accountants, underwriters (excluding discounts and commissions) and other Persons retained by the Company or the holders of Investor Registrable Securities (all such expenses being herein called "REGISTRATION EXPENSES"), shall be borne as provided in this Agreement, except that the Company shall, in any event, pay its internal expenses (including, without limitation, all salaries and expenses of its officers and employees performing legal or accounting duties), the expense of any annual audit or quarterly review, the expense of any liability insurance and the expenses and fees for listing the securities to be registered on each securities exchange on which similar securities issued by the Company are then listed or on the NASD automated quotation system.

(b) In connection with each Demand Registration and each Piggyback Registration, the Company shall reimburse the holders of Registrable Securities included in such registration for the reasonable fees and disbursements of one counsel chosen by the holders of a majority of the Investor Registrable Securities included in such registration and for the reasonable fees and disbursements of each additional counsel retained by any holder of Registrable Securities for the purpose of rendering a legal opinion on behalf of such holder in connection with any underwritten Demand Registration or Piggyback Registration.

-8-

(c) To the extent Registration Expenses are not required to be paid by the Company, each holder of securities included in any registration hereunder shall pay those Registration Expenses allocable to the registration of such holder's securities so included, and any Registration Expenses not so allocable shall be borne by all sellers of securities included in such registration in proportion to the aggregate selling price of the securities to be so registered.

6. INDEMNIFICATION.

(a) The Company agrees to indemnify, to the extent permitted by law, each holder of Registrable Securities, its officers, directors and partners, legal counsel, accountants and each Person who controls such holder (within the meaning of the Securities Act) against all losses, claims, damages, liabilities and expenses (including investigation costs and costs of defending same) caused by (i) any untrue or alleged untrue statement of material fact contained in any registration statement, prospectus or preliminary prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as the same are caused by or contained in any information furnished in writing to the Company by such holder expressly for use therein or by such holder's failure to deliver a copy of the registration statement or prospectus or any amendments or supplements thereto after the Company has furnished such holder with a sufficient number of copies of the same or any violation of federal or state securities laws, rules or regulations relating to actions or inactions required by such holder, its officers, directors or partners or any Person who controls such holder (within the meaning of the Securities Act) in connection with any such registration or qualification or (ii) any violation by the Company of the Securities Act or any regulation thereunder applicable to the Company and relating to action or inaction required of the Company in connection with any such registration, qualification or compliance. In connection with an underwritten offering, the Company shall indemnify such underwriters, their officers and directors and each Person who controls such underwriters (within the meaning of the Securities Act) to the same extent as provided above with respect to the indemnification of the holders of Registrable Securities.

(b) In connection with any registration statement in which a holder of Registrable Securities is participating, each such holder shall furnish to the Company in writing such information and affidavits as the Company reasonably requests for use in connection with any such registration statement or prospectus and, to the extent permitted by law, shall indemnify the Company, officers, directors and partners, and each Person who controls the Company (within the meaning of the Securities Act) against any losses, claims, damages, liabilities and expenses (including investigations and cost of defending same) resulting from any untrue or alleged untrue statement of material fact contained in the registration statement, prospectus or preliminary prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, but only to the extent that such untrue statement or omission is contained in any information or affidavit so furnished in writing by such holder and stated to be specifically for use therein; provided that the obligation to indemnify shall be individual, not joint and several, for each holder and shall be limited to the net amount of proceeds received by such holder from the sale of Registrable Securities pursuant to such registration statement.

-9-

(c) Any Person entitled to indemnification hereunder shall
(i) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided that the failure to give prompt notice shall not impair any Person's right to indemnification hereunder to the extent such failure has not prejudiced the indemnifying party) and (ii) unless in such indemnified party's reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist with respect to such claim, permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying party shall not be subject to any liability for any settlement made by the indemnified party without its consent (but such consent shall not be unreasonably withheld). An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim shall not be obligated to pay the fees and expenses of more than one counsel for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party a conflict of interest may exist between such indemnified party and any other of such indemnified parties with respect to such claim.

(d) The indemnification provided for under this Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of the indemnified party or any officer, director, legal counsel, accountant, partner or controlling Person of such indemnified party and shall survive the transfer of securities. The Company also agrees to make such provisions, as are reasonably requested by any indemnified party, for contribution to such party in the event the Company's indemnification is unavailable for any reason.

(e) If the indemnification provided for in this paragraph 6 is held by a court of competent jurisdiction to be unavailable to an indemnified party with respect to any loss, liability, claim, damage, or expense referred to therein, then the indemnifying party, in lieu of indemnifying such indemnified party hereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such loss, liability, claim, damage, or expense in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of the indemnified party on the other in connection with the statements or omissions that resulted in such loss, liability, claim, damage, or expense as well as any other relevant equitable considerations. The relative fault of the indemnifying party and of the indemnified party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the indemnifying party or by the indemnified party and the parties' relative intent, knowledge, access to information, and opportunity to correct or prevent such statement or omission.

(f) Notwithstanding the foregoing, to the extent that the provisions on indemnification and contribution contained in the underwriting agreement entered into in connection with the underwritten public offering are in conflict with the foregoing provisions, the provisions in the underwriting agreement shall control.

7. PARTICIPATION IN UNDERWRITTEN REGISTRATIONS. No Person may participate in any registration hereunder which is underwritten unless such Person (i) agrees to sell such Person's securities on the basis provided in any underwriting arrangements approved by the Person or Persons entitled hereunder to approve such arrangements and (ii) completes and executes all questionnaires,

-10-

powers of attorney, indemnities, underwriting agreements and other documents required under the terms of such underwriting arrangements; provided that no holder of Investor Registrable Securities included in any underwritten registration shall be required to make any representations or warranties to the Company or the underwriters (other than representations and warranties regarding such holder and such holder's intended method of distribution) or to undertake any indemnification obligations to the Company or the underwriters with respect thereto, except as otherwise provided in paragraph 6 hereof. The Company's obligations under this Agreement with respect to each seller of Registrable Securities shall be conditioned upon such seller's compliance with the following:

(a) Such seller shall cooperate with the Company in connection with the preparation of the registration statement, and for so long as the Company is obligated to keep the registration statement effective, shall provide to the Company, in writing, for use in the registration statement, all information reasonably requested by the Company regarding such seller and such other information relating to such seller as may be necessary to enable the Company to prepare the registration statement and prospectus covering the Registrable Securities, to maintain the currency and effectiveness thereof, and to otherwise comply with all applicable requirements of law in connection therewith;

(b) during such time as such seller may be engaged in a distribution of Registrable Securities, such seller will comply with all applicable laws including but not limited to Rules 10b-6 and 10b-7 promulgated under the Securities Exchange Act of 1934, as amended (the "EXCHANGE ACT") and pursuant thereto will, among other thing: (A) not engage in any stabilization activity in connection with the securities of the Company in contravention of such rules; (B) distribute the Registrable Securities owned by such seller solely in the manner described in the registration statement; (C) cause to be furnished to each underwriter, agent or broker-dealer to and through whom the Registrable Securities owned by such seller may be offered, or to the offeree if an offer is made directly by such seller, such copies of the prospectus (as amended and supplemented to such date) and documents incorporated by reference therein as may be required by such underwriter, agent, broker-dealer or offeree; and (D) not bid for or purchase any securities of the Company or attempt to induce any person to purchase any securities of the Company other than as permitted under the Exchange Act; and

(c) on notice from the Company of the happening of any of the events specified in paragraph 4(e) above, if it requires the suspension by such seller of the distribution of any of the Registrable Securities, then such seller shall cease offering or distributing the Registrable Securities until such time as the Company notifies such seller that offering and distribution of the Registrable Securities may recommence (which in any event shall be no later than immediately after the filing of the supplemented or amended prospectus contemplated by Section 4(e)).

8. RULE 144 REPORTING. With a view to making available the benefits of certain rules and regulations of the Securities and Exchange Commission that may permit the sale of Registrable Securities to the public without registration, the Company agrees to use its best efforts to:

-11-

(a) make and keep public information regarding the Company available as those terms are understood and defined in Rule 144 under the Securities Act;

(b) file with the Securities and Exchange Commission in a timely manner all reports and other documents required of the Company under the Securities Act and the Securities Exchange Act of 1934, as amended (the "EXCHANGE ACT") at any time after it has become subject to such reporting requirements; and

(c) so long as a holder owns any Registrable Securities, furnish to the holder forthwith upon written request a written statement by the Company as to its compliance with the reporting requirements of Rule 144, and of the Securities Act and the Exchange Act, a copy of the most recent annual or quarterly report of the Company, and such other reports and documents so filed as a holder may reasonably request in availing itself of any rule or regulation of the Securities and Exchange Commission allowing a holder to sell any such securities without registration.

9. DEFINITIONS.

"INVESTOR REGISTRABLE SECURITIES" means any shares of Common Stock held by Navistar and its affiliates and any other shares of Common Stock held by a person who is a party to this Agreement and are designated as such by Navistar.

"OTHER REGISTRABLE SECURITIES" means any shares of Common Stock held by a person who is a party to this Agreement that do not constitute Investor Registrable Securities.

"REGISTRABLE SECURITIES" means Investor Registrable Securities and Other Registrable Securities. As to any particular Registrable Securities, such securities shall cease to be Investor or Other Registrable Securities when they have been distributed to the public pursuant to an offering registered under the Securities Act or sold to the public through a broker, dealer or market maker in compliance with Rule 144 under the Securities Act (or any similar rule then in force). For purposes of this Agreement, a Person shall be deemed to be a holder of Registrable Securities whenever such Person has the right to acquire such Registrable Securities (upon conversion or exercise in connection with a transfer of securities or otherwise, but disregarding any restrictions or limitations upon the exercise of such right), whether or not such acquisition has actually been effected, and such Person shall be entitled to exercise the rights of a holder of Registrable Securities hereunder.

"SUBSIDIARY" means, with respect to any Person, any corporation, partnership, association or other business entity of which (i) if a corporation, a majority of the total voting power of shares of stock entitled (without regard to the occurrence of any contingency) to vote in the election of directors, managers or trustees thereof is at the time owned or controlled, directly or indirectly, by that Person or one or more of the other Subsidiaries of that Person or a combination thereof, or (ii) if a partnership, association or other business entity, a majority of the partnership or other similar ownership interest thereof is at the time owned or controlled, directly or indirectly, by any Person or one or more Subsidiaries of that Person or a combination thereof. For purposes hereof, a Person or Persons shall be deemed to have a majority ownership interest in a partnership, association or other business entity if such Person or Persons shall be allocated a majority of

-12-

partnership, association or other business entity gains or losses or shall be or control any managing director or general partner of such partnership, association or other business entity. For purposes hereof, reference to a "Subsidiary" of the Company shall be given effect only at such times as the Company has one or more Subsidiaries.

10. MISCELLANEOUS.

(a) NO INCONSISTENT AGREEMENTS. The Company shall not hereafter enter into any agreement with respect to its securities which is inconsistent with or violates the rights granted to the holders of Registrable Securities in this Agreement.

(b) ADJUSTMENTS AFFECTING REGISTRABLE SECURITIES. The Company shall not take any action, or permit any change to occur, with respect to its securities which would adversely affect the ability of the holders of Registrable Securities to include such Registrable Securities in a registration undertaken pursuant to this Agreement or which would adversely affect the marketability of such Registrable Securities in any such registration (including, without limitation, effecting a stock split or a combination of shares).

(c) REMEDIES. Any Person having rights under any provision of this Agreement shall be entitled to enforce such rights specifically to recover damages caused by reason of any breach of any provision of this Agreement and to exercise all other rights granted by law. The parties hereto agree and acknowledge that money damages may not be an adequate remedy for any breach of the provisions of this Agreement and that any party may in its sole discretion apply to any court of law or equity of competent jurisdiction (without posting any bond or other security) for specific performance and for other injunctive relief in order to enforce or prevent violation of the provisions of this Agreement.

(d) AMENDMENTS AND WAIVERS. Except as otherwise provided herein, no modification, amendment or waiver of any provision of this Agreement shall be effective against the Company or the holders of Registrable Securities unless such modification, amendment or waiver is approved in writing by the Company and the holders of at least a majority of the Registrable Securities then in existence, which majority shall include a majority of the Investor Registrable Securities then in existence; provided that no such amendment or action which materially adversely affects any one holder of Registrable Securities, as such, vis-a-vis the other holders of Registrable Securities, as such, shall be effective against such holder without the prior written consent of such holder. The failure of any party to enforce any of the provisions of this Agreement shall in no way be construed as a waiver of such provisions and shall not affect the right of such party thereafter to enforce each and every provision of this Agreement in accordance with its terms.

(e) ADDITIONAL PARTIES. The Board of Directors of the Company shall be entitled, but not obligated, to allow any purchaser of Common Stock (or securities or rights convertible or exercisable into Common Stock) to execute a counterpart to this Agreement and become a party hereto (each, an "ADDITIONAL PARTY"), in which case the Common Stock issued or issuable to any such Additional Party shall be deemed "Registrable Securities" for purposes of this Agreement. Except

-13-

as set forth in this paragraph 10(e) and in paragraph 1(g), the Company will not grant to any other Persons any registration rights.

(f) SUCCESSORS AND ASSIGNS. All covenants and agreements in this Agreement by or on behalf of any of the parties hereto shall bind and inure to the benefit of the respective successors and assigns of the parties hereto whether so expressed or not. In addition, whether or not any express assignment has been made, the provisions of this Agreement which are for the benefit of the purchasers or holders of Registrable Securities are also for the benefit of, and enforceable by, any subsequent holder of Registrable Securities. Notwithstanding the foregoing, (a) in order to obtain the benefit of this Agreement, any subsequent holder of Registrable Securities must execute a counterpart to this Agreement, thereby agreeing to be bound the terms hereof and (b) the right to designate "Investor Registrable Securities" is not assignable unless the person holding such right explicitly assigns such right to the assignee or transferee of all or a portion of its Registrable Securities.

(g) SEVERABILITY. Whenever possible, each provision of this Agreement shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement is held to be prohibited by or invalid under applicable law, such provision shall be ineffective only to the extent of such prohibition or invalidity, without invalidating the remainder of this Agreement.

(h) COUNTERPARTS. This Agreement may be executed simultaneously in two or more counterparts, any one of which need not contain the signatures of more than one party, but all such counterparts taken together shall constitute one and the same Agreement.

(i) DESCRIPTIVE HEADINGS. The descriptive headings of this Agreement are inserted for convenience only and do not constitute a part of this Agreement.

(j) GOVERNING LAW. The corporate law of the State of Delaware shall govern all issues and questions concerning the relative rights of the Company and its stockholders. All other issues and questions concerning the construction, validity, interpretation and enforcement of this Agreement and the exhibits and schedules hereto shall be governed by, and construed in accordance with, the laws of the State of Ohio, without giving effect to any choice of law or conflict of law rules or provisions (whether of the State of Ohio or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of Ohio. In furtherance of the foregoing, the internal law of the State of Illinois shall control the interpretation and construction of this Agreement (and all schedules and exhibits hereto), even though under that jurisdiction's choice of law or conflict of law analysis, the substantive law of some other jurisdiction would ordinarily apply.

(k) NOTICES. All notices, demands or other communications to be given or delivered under or by reason of the provisions of this Agreement shall be in writing and shall be deemed to have been given when delivered personally to the recipient, sent to the recipient by reputable overnight courier service (charges prepaid) or mailed to the recipient by certified or registered mail, return receipt requested and postage prepaid. Such notices, demands and other communications shall be sent to holder of Registrable Securities at the address indicated on the

-14-

books and records of the Company and to the Company at its principal executive office (to the attention of the Company's president) or to such other address or to the attention of such other person as the recipient party has specified by prior written notice to the sending party.

IN WITNESS WHEREOF, the parties have executed this Agreement as of the date first written above.
