Item 6. Indemnification of Directors and Officers.

Section 102(b)(7) of the Delaware General Corporation Law permits a Delaware corporation to limit the liability of its directors through a provision in its certificate of incorporation, and provides, in pertinent part, as follows:

(b) In addition to the matters required to be set forth in the certificate of incorporation by subsection (a) of this section, the certificate of incorporation may also contain any or all of the following matters:

* * *

(7) A provision eliminating or limiting the personal liability of a director to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, provided that such provision shall not eliminate or limit the liability of a director:
(i) for any breach of the director's duty of loyalty to the corporation or its stockholders; (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law; (iii) under section 174 of this title; or (iv) for any transaction from which the director derived an improper personal benefit. No such provision shall eliminate or limit the liability of a director for any act or omission occurring prior to the date when such provision becomes effective. . . .

Article XI of the Certificate of Incorporation of the Company, as amended, limits the personal liability of the directors of the Company and provides as follows:

SECTION 1. Limitation of Directors' Liability.

A. No director of the corporation shall be personally liable to the Corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, except, to the extent provided by applicable law, for liability (i) for breach of the director's duty of loyalty to the Corporation or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) pursuant to Section 174 of the Delaware General Corporation Law or (iv) for any transaction from which the director derived an improper personal benefit. If the Delaware General Corporation Law is hereafter amended to authorize corporate action further limiting or eliminating the personal liability of directors, then the liability of each director of the Corporation shall be limited or eliminated to the full extent permitted by the Delaware General Corporation Law as so amended from time to time.

3

B. Neither the amendment nor repeal of this Section 1, nor the adoption of any provision of the Certificate of Incorporation inconsistent with this Section 1, shall eliminate or reduce the effect of this Section 1, in respect of any matter occurring, or any cause of action, suit or claim that, but for this Section 1, would accrue or arise, prior to such amendment, repeal or adoption of an inconsistent provision.

Section 145 of the Delaware General Corporation Law governs indemnification by a Delaware corporation and provides as follows:

(a) A corporation shall have power to 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 the person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, 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 the person in connection with such action, suit or proceeding if the person acted in good faith and in a manner the 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 the 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 the 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 reasonable cause to believe that the person's conduct was unlawful.

(b) A corporation shall have power to 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 the person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against expenses (including attorneys' fees) actually and reasonably

4

incurred by the person in connection with the defense or settlement of such action or suit if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the corporation and except that no 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 or the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery or such other court shall deem proper.

(c) To the extent that a director, officer, employee or agent of a corporation has been successful on the merits or otherwise in defense of any action, suit or proceeding referred to in subsections
(a) and (b) of this section, or in defense of any claim, issue or matter therein, he shall be indemnified against expenses (including attorneys' fees) actually and reasonably incurred by him in connection therewith.

(d) Any indemnification under subsections (a) and (b) of this section (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, employee or agent is proper in the circumstances because the person has met the applicable standard of conduct set forth in subsections (a) and (b) of this section. 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.

(e) Expenses (including attorneys' fees) incurred by an officer or director in defending any civil, criminal, administrative or investigative action, suit or proceeding may 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 such director or officer to repay such amount if it shall ultimately be determined that he is not entitled to be indemnified by the corporation as authorized in this section. 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.

5

(f) The indemnification and advancement of expenses provided by, or granted pursuant to, the other subsections of this section shall not be deemed exclusive of any other rights to which those seeking indemnification or advancement of expenses may be entitled under any bylaw, agreement, vote of stockholders or disinterested directors or otherwise, both as to action in his official capacity and as to action in another capacity while holding such office.

(g) A corporation shall have power to purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against any liability asserted against him and incurred by him in any such capacity, or arising out of his status as such, whether or not the corporation would have the power to indemnify him against such liability under this section.

(h) For purposes of this section, 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 which, if its separate existence had continued, would have had power and authority to indemnify its directors, officers, and 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, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, shall stand in the same position under this section with respect to the resulting or surviving corporation as he would have with respect to such constituent corporation if its separate existence had continued.

(i) For purposes of this section, references to "other enterprises" shall include employee benefit plans; references to "fines" shall include any excise taxes assessed on a person with respect to any employee benefit plan; and references to "serving at the request of the corporation" shall include any service as a director, officer, employee or agent of the corporation which imposes duties on, or involves services by, such director, officer, employee or agent with respect to an employee benefit plan, its participants or beneficiaries; and a person who acted in good faith and in a manner he reasonably believed to be in the interest of the participants and beneficiaries of an employee benefit plan shall be deemed to

6

have acted in a manner "not opposed to the best interests of the corporation" as referred to in this section.

(j) The indemnification and advancement of expenses provided by, or granted pursuant to, this section shall, unless otherwise provided when authorized or ratified, continue as to a person who has ceased to be a director, officer, employee or agent and shall inure to the benefit of the heirs, executors and administrators of such a person.

(k) The Court of Chancery is hereby vested with exclusive jurisdiction to hear and determine all actions for advancement of expenses or indemnification brought under this section or under any bylaw, agreement, vote of stockholders or disinterested directors, or otherwise. The Court of Chancery may summarily determine a corporation's obligation to advance expenses (including attorneys' fees).

Article VIII of the By-laws of the Company governs indemnification by the Company and provides as follows:

ARTICLE VIII.

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

7

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.

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 office 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 and 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

8

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 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

9

(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. For purposes of this Article VIII, references to "other enterprises" shall include employee benefit plans, references to "fines" shall include any excise taxes assessed on a person with respect to any employee benefit plan, and references to "serving at the request of the Corporation" shall include any service as a director, officer, employee or agent of the Corporation which imposes duties on, or involves services by, such director, officer, employee, or agent with respect to any employee benefit plan, its participants and beneficiaries, and a person who acted in good faith and in a manner such person reasonably believed to be in the interest of the participants and beneficiaries of an employee benefit plan shall be deemed to have acted in a manner "not opposed to the best interest of the Corporation" as referred to in this Article VIII.

Article 18 of the Company's Long-Term Equity Incentive Plan provides for indemnification by the Company, as follows:

Each person who is or shall have been a member of the Committee, or of the Board, shall be indemnified by the Company against and from any loss, cost, liability, or expense that may be imposed upon or reasonably incurred by him or her in connection with or resulting from any claim, action, suit, or proceeding to which he or she may be a party or in which he or she may be involved by reason of any action taken or failure to act under the Plan. Such person shall be indemnified by the Company for all amounts paid by him or her in settlement thereof, with the Company's approval, or paid by him or her in satisfaction of any

10

judgment in any such action, suit, or proceeding against him or her, provided he or she shall give the Company an opportunity, at its own expense, to handle and defend the same before he or she undertakes to handle and defend it on his or her own behalf. The foregoing right of indemnification shall not be exclusive of any other rights of indemnification to which such persons may be entitled under the Company's Articles of Incorporation or Bylaws, as a matter of law, or otherwise, or any power that the Company may have to indemnify them or hold them harmless.

The Registrant has purchased insurance coverage under a policy which insures directors and officers against certain liabilities which might be incurred by them in such capacities.

Item 7. Exemption from Registration Claimed.

Not Applicable.

Item 8. Exhibits.

See the Index to Exhibits attached hereto at page 15.

Item 9. Undertakings.

A. The undersigned Registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;

(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement
(or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement; and

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

provided, however, that paragraphs A(1)(i) and A(1)(ii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports

11

filed with or furnished to the Commission by the Registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in this registration statement.

(2) That, for the purpose 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.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

B. The undersigned Registrant hereby undertakes 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 Securities 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.

C. Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Registrant pursuant to the provisions described in Item 6 of this Part II, 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 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 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 Act and will be governed by the final adjudication of such issue.

12

(1) Article VIII Effective Date. The time and date of the legal effectiveness of the merger of RYMAC Mortgage Investment Corporation with and into the Corporation.

(2) Control. The possession, direct or indirect, of the power to direct or cause the direction of the management and policies of a Person, whether through the ownership of voting securities, by contract, or otherwise. 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 l.382-2T(f)(9).

20

(6) 47 Percentage Point Increase. 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. A "higher tier entity" with respect to the Corporation, as that term is defined in Treasury Regulations
Section l.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
Section or provision having similar effect.

(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.

(11) Permitted Transferee. Any transferee with a Prohibited Ownership Percentage as to which the Board of Directors has consented pursuant to Subparagraph C(2) or C(3) of Section 1.

(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).

(13) Prohibited Ownership Percentage. Any ownership in the Corporation that would cause a Person or Public Group to be a "5-percent shareholder" of the Corporation within the meaning of Treasury Regulations Section 1.382-2T(g)(1)(i) or (ii). For this purpose, whether a Person or Public Group

21

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
l.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). In addition, for the purpose of determining whether any Person or Public Group has a Prohibited Ownership Percentage as of any date, the definition of Stock set forth in Subparagraph A(15) of Section 1 shall be applied in lieu of the definition in Treasury Regulations Section 1.382-2T(f)(18), except that any option shall be treated as Stock only to the extent treating it as Stock would cause an increase in ownership of such Person and such option would be deemed exercised pursuant to Treasury Regulations in effect from time to time (disregarding whether treating such option as exercised would cause an ownership change).

(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

22

entitled under the Internal Revenue Code, free of restrictions under
Section 382 of the Internal Revenue Code.

Section l.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.

(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.

23

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.

24

(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 l 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 l.382-2T(c)) and
(ii) the proposed transferee shall have delivered a Transferee Undertaking.

(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 l, such Transfer would otherwise be permitted under Subparagraph C(2) if such Transfer were proposed to be made by an Effective Date Tier Entity.

25

(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 1, 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 l, 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 l, 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

26

without restriction under Paragraph B of Section l 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 l.

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 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

27

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 1 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

28

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, 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

29

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.

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 1, 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 l, 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 l, 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

49

without restriction under Paragraph B of Section l 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 l.

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 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

50

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 1 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

51

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, 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

52

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.

53

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.

If any Award or Director Option granted under this Plan is canceled, terminates, expires, or lapses for any reason (with the exception of the termination of a Tandem SAR upon exercise of the related Option, or the termination of a related Option upon exercise of the corresponding Tandem SAR), any Shares subject to such Award or Director Option again shall be available for the grant of an Award or Director Option under the Plan.

4.3 ADJUSTMENTS IN AUTHORIZED SHARES. In the event of any change in corporate capitalization, such as a stock split, or a corporate transaction, such as any merger, consolidation, separation, including a spin-off, or other distribution of stock or property of the Company, any reorganization (whether or not such reorganization comes within the definition of such term in Code
Section 368), or any partial or complete liquidation of the Company, such adjustment shall be made in the number and class of Shares available in the Share Pool and in the number and class of and/or price of Shares subject to outstanding Awards granted under the Plan, as may be determined to be appropriate and equitable by the Committee, in its sole discretion, to prevent dilution or enlargement of rights; provided, however, that the number of Shares subject to any Award shall always be a whole

65

number. If, pursuant to the preceding sentence, an adjustment is made to outstanding Options held by Participants, a corresponding adjustment shall be made to outstanding Director Options and if, pursuant to the preceding sentence, an adjustment is made to the number of Shares authorized for issuance under the Plan, a corresponding adjustment shall be made to the number of Shares subject to each Director Option thereafter granted pursuant to Section 6.9.

ARTICLE 5. ELIGIBILITY AND PARTICIPATION

5.1 ELIGIBILITY. Persons eligible to participate in this Plan include all officers and key employees of the Company, as determined by the Committee, including Employees who are members of the Board and Employees who reside in countries other than the United States of America.

5.2 ACTUAL PARTICIPATION. Subject to the provisions of the Plan, the Committee may, from time to time, select from all eligible Employees, those to whom Awards shall be granted and shall determine the nature and amount of each Award. Each Eligible Director shall receive nondiscretionary Director Options in accordance with, and only in accordance with, Section 6.9 hereof.

ARTICLE 6. STOCK OPTIONS

6.1 GRANT OF OPTIONS. Subject to the terms and provisions of the Plan, Options may be granted, either by the Committee or the Board, to one or more Participants in such number, and upon such terms, and at any time and from time to time as shall be determined by the Committee. The Committee or the Board shall have the authority to grant Incentive Stock Options or to grant Nonqualified Stock Options or to grant both types of Options. In the case of Incentive Stock Options, the terms and conditions of such grants shall be subject to, and comply with, such rules as may be prescribed by Section 422 of the Code, as from time to time amended, and any regulations implementing such statute, including, without limitation, the requirements of Code Section 422(d) which limit the aggregate Fair Market Value of Shares (determined at the time that such Option is granted) for which Incentive Stock Options are exercisable for the first time to $100,000 per calendar year. Each provision of the Plan and of each written Award Agreement relating to an Option designated as an Incentive Stock Option shall be construed so that such Option qualifies as an Incentive Stock Option, and any provision that cannot be so construed shall be disregarded.

66

6.2 AWARD AGREEMENT. Each Option grant shall be evidenced by an Award Agreement that shall specify the Option Price, the duration of the Option, the number of Shares to which the Option pertains, and such other provisions as the Committee shall determine. The Award Agreement also shall specify whether the Option is intended to be an ISO or an NQSO.

6.3 OPTION PRICE. Unless otherwise designated by the Committee at the time of grant, the Option Price for each grant of an Option under this Plan shall be at least equal to one hundred percent (100%) of the Fair Market Value of a Share on the date the Option is granted. Notwithstanding any provision contained herein, in the case of an Incentive Stock Option, the exercise price at the time such Incentive Stock Option is granted to any Employee who, at the time of such grant, owns (within the meaning of Section 425(d) of the Code) more than ten percent of the voting power of all classes of stock of the Company or a subsidiary, shall not be less than 110% of the per Share Fair Market Value on the date of grant.

6.4 DURATION OF OPTIONS. Each Option granted to an Employee shall expire at such time as the Committee shall determine at the time of grant; provided, however, that in the case of an Incentive Stock Option, an Employee may not exercise such Incentive Stock Option after (a) the date which is ten years (five years in the case of a Participant who owns more than ten percent of the voting power of the Company or a subsidiary) after the date on which such Incentive Stock Option is granted; or (b) the date which is three months (twelve months in the case of a Participant who becomes disabled, as defined in
Section 22(e)(3) of the Code, or who dies) after the date on which he ceases to be an Employee of the Company or a subsidiary.

6.5 EXERCISE OF OPTIONS. Options granted under this Article 6 shall be exercisable at such times and be subject to such restrictions and conditions as the Committee shall in each instance approve, which need not be the same for each grant or for each Participant.

6.6 PAYMENT. Options granted under this Article 6 shall be exercised by the delivery of a written notice of exercise to the Company, setting forth the number of Shares with respect to which the Option is to be exercised, accompanied by full payment for the Shares.

The Option Price upon exercise of any Option shall be payable to the Company in full either: (a) in cash or its equivalent, or (b) by tendering previously acquired Shares having an aggregate Fair Market Value at the time of exercise equal to the total Option Price (provided that the Shares which are

67

tendered must have been held by the Participant for at least six (6) months prior to their tender to satisfy the Option Price), or (c) by a combination of
(a) and(b).

As soon as practicable after receipt of a written notification of exercise and full payment, the Company shall deliver to the Participant, in the Participant's name, Share certificates in an appropriate amount based upon the number of Shares purchased under the Option(s).

6.7 RESTRICTIONS ON SHARE TRANSFERABILITY. The Committee may impose such restrictions on any Shares acquired pursuant to the exercise of an Option granted under this Article 6 as it may deem advisable, including, without limitation, restrictions under applicable federal securities laws, under the requirements of any stock exchange or market upon which such Shares are then listed and/or traded, and under any blue sky or state securities laws applicable to such Shares.

6.8 TERMINATION OF EMPLOYMENT. Each Option Award Agreement shall set forth the extent to which the Participant shall have the right to exercise the Option following termination of the Participant's employment with the Company and/or its Subsidiaries. Such provisions shall be determined in the sole discretion of the Committee, shall be included in the Award Agreement entered into with each Participant, need not be uniform among all Options issued pursuant to the Plan, and may reflect distinctions based on the reasons for termination of employment.

6.9 DIRECTOR OPTIONS. Notwithstanding anything else contained herein to the contrary, each Eligible Director shall receive, on April 16, 1997, provided that the Eligible Director is serving as a member of the Board on such date, a grant of a Director Option to purchase 35,000 Shares at an exercise price per Share equal to the Fair Market Value on the date of grant. Each Eligible Director who is first elected to the Board after April 16, 1997 shall receive, on the day following such election, a grant of a Director Option to purchase 35,000 Shares at an exercise price per Share equal to the Fair Market Value on the date of grant. A Director Option shall be exercisable until the earlier to occur of the following two dates: (a) the tenth anniversary of the date of grant of such Director Option; or (b) twelve months after the date the Eligible Director ceases to be a member of the Board, except that if the Eligible Director ceases to be a member of the Board after having been convicted of, or pled guilty or nolo contendere to, a felony, his Director Option shall be canceled on the date he ceases to be a member of the Board. Each Director Option shall vest twenty percent (20%) on the annual anniversary date after the date of grant; and any unvested Director Options shall be forfeited by the Eligible

68

Director if he terminates his service on the Board prior to satisfaction of such vesting requirement. An Eligible Director may pay the exercise price of a Director Option in the manner described in Section 6.6. Each Director Option shall be evidenced by an agreement between the Company and the Eligible Director.

6.10 NONTRANSFERABILITY OF OPTIONS AND DIRECTOR OPTIONS.

(a) INCENTIVE STOCK OPTIONS AND DIRECTOR OPTIONS. No ISO or Director Option granted under the Plan may be sold, transferred, pledged, assigned, or otherwise alienated or hypothecated, other than by will or by the laws of descent and distribution. Further, all ISOs and Director Options granted to a Participant or Eligible Director under the Plan shall be exercisable during his or her lifetime only by such Participant or Eligible Director

(b) NONQUALIFIED STOCK OPTIONS. Except as otherwise provided in a Participant's Award Agreement, no NQSO granted under this Article 6 may be sold, transferred, pledged, assigned, or otherwise alienated or hypothecated, other than by will or by the laws of descent and distribution. Further, except as otherwise provided in a Participant's Award Agreement, all NQSOs granted to a Participant under this Article 6 shall be exercisable during his or her lifetime only by such Participant

ARTICLE 7. STOCK APPRECIATION RIGHTS

7.1 GRANT OF SARS. Subject to the terms and conditions of the Plan, SARs may be granted to Participants at any time and from time to time as shall be determined by the Committee. The Committee may grant Freestanding SARs, Tandem SARs, or any combination of these forms of SAR.

The Committee shall have complete discretion in determining the number of SARs granted to each Participant (subject to Article 4 herein) and, consistent with the provisions of the Plan, in determining the terms and conditions pertaining to such SARs.

Unless otherwise designated by the Committee at the time of grant, the grant price of a Freestanding SAR shall equal the Fair Market Value of a Share on the date of grant of the SAR. The grant price of Tandem SARs shall equal the Option Price of the related Option.

69

7.2 EXERCISE OF TANDEM SARS. Tandem SARs may be exercised for all or part of the Shares subject to the related Option upon the surrender of the right to exercise the equivalent portion of the related Option. A Tandem SAR may be exercised only with respect to the Shares for which its related Option is then exercisable.

Notwithstanding any other provision of this Plan to the contrary, with respect to a Tandem SAR granted in connection with an ISO: (i) the Tandem SAR will expire no later than the expiration of the underlying ISO; (ii) the value of the payout with respect to the Tandem SAR may be for no more than one hundred percent (100%) of the difference between the Option Price of the underlying ISO and the Fair Market Value of the Shares subject to the underlying ISO at the time the Tandem SAR is exercised; and (iii) the Tandem SAR may be exercised only when the Fair Market Value of the Shares subject to the ISO exceeds the Option Price of the ISO.

7.3 EXERCISE OF FREESTANDING SARS. Freestanding SARs may be exercised upon whatever terms and conditions the Committee, in its sole discretion, imposes upon them.

7.4 SAR AGREEMENT. Each SAR grant shall be evidenced by an Award Agreement that shall specify the grant price, the term of the SAR, and such other provisions as the Committee shall determine.

7.5 TERM OF SARS. The term of an SAR granted under the Plan shall be determined by the Committee, in its sole discretion; provided, however, that unless otherwise designated by the Committee, such term shall not exceed ten
(10) years.

7.6 PAYMENT OF SAR AMOUNT. Upon exercise of an SAR, a Participant shall be entitled to receive payment from the Company in an amount determined by multiplying:

(a) The difference between the Fair Market Value of a Share on the date of exercise over the grant price; by

(b) The number of Shares with respect to which the SAR is exercised.

At the discretion of the Committee, the payment upon SAR exercise may be in cash, in Shares of equivalent value, in Restricted Shares of equivalent value, or in some combination thereof.

70

7.7 TERMINATION OF EMPLOYMENT. Each SAR Award Agreement shall set forth the extent to which the Participant shall have the right to exercise the SAR following termination of the Participant's employment with the Company and/or its Subsidiaries. Such provisions shall be determined in the sole discretion of the Committee, shall be included in the Award Agreement entered into with Participants, need not be uniform among all SARs issued pursuant to the Plan, and may reflect distinctions based on the reasons for termination of employment.

7.8 NONTRANSFERABILITY OF SARS. Except as otherwise provided in a Participant's Award Agreement, no SAR granted under the Plan may be sold, transferred, pledged, assigned, or otherwise alienated or hypothecated, other than by will or by the laws of descent and distribution. Further, except as otherwise provided in a Participant's Award Agreement, all SARs granted to a Participant under the Plan shall be exercisable during his or her lifetime only by such Participant.

ARTICLE 8. RESTRICTED STOCK

8.1 GRANT OF RESTRICTED STOCK. Subject to the terms and provisions of the Plan, the Committee, at any time and from time to time, may grant Shares of Restricted Stock to Participants in such amounts as the Committee shall determine.

8.2 RESTRICTED STOCK AGREEMENT. Each Restricted Stock grant shall be evidenced by an Award Agreement that shall specify the Period(s) of Restriction, the number of Shares of Restricted Stock granted, and such other provisions as the Committee shall determine.

8.3 TRANSFERABILITY. Except as provided in this Article 8, the Shares of Restricted Stock granted herein may not be sold, transferred, pledged, assigned, or otherwise alienated or hypothecated until the end of the applicable Period of Restriction established by the Committee and specified in the Restricted Stock Award Agreement, or upon earlier satisfaction of any other conditions, as specified by the Committee in its sole discretion and set forth in the Restricted Stock Agreement. All rights with respect to the Restricted Stock granted to a Participant under the Plan shall be available during his or her lifetime only to such Participant.

8.4 OTHER RESTRICTIONS. Subject to Article 11 herein, the Committee may impose such other conditions and/or restrictions on any Shares of Restricted Stock granted pursuant to the Plan as it may deem advisable including, without limitation, a requirement that Participants pay a stipulated purchase price for each Share

71

of Restricted Stock, restrictions based upon the achievement of specific performance goals (Company-wide, divisional, and/or individual), time-based restrictions on vesting following the attainment of the performance goals, and/or restrictions under applicable federal or state securities laws.

The Company shall retain the certificates representing Shares of Restricted Stock in the Company's possession until such time as all conditions and/or restrictions applicable to such Shares have been satisfied.

Except as otherwise provided in this Article 8, Shares of Restricted Stock covered by each Restricted Stock grant made under the Plan shall become freely transferable by the Participant after the last day of the applicable Period of Restriction.

8.5 VOTING RIGHTS. Unless otherwise designated by the Committee at the time of grant, Participants holding Shares of Restricted Stock granted hereunder may exercise full voting rights with respect to those Shares during the Period of Restriction.

8.6 DIVIDENDS AND OTHER DISTRIBUTIONS. Unless otherwise designated by the Committee at the time of grant, Participants holding Shares of Restricted Stock granted hereunder may be credited with regular cash dividends paid with respect to the underlying Shares while they are so held during the Period of Restriction. The Committee may apply any restrictions to the dividends that the Committee deems appropriate. Without limiting the generality of the preceding sentence, if the grant or vesting of Restricted Shares granted to a Named Executive Officer is designed to comply with the requirements of the Performance-Based Exception, the Committee may apply any restrictions it deems appropriate to the payment of dividends declared with respect to such Restricted Shares, such that the dividends and/or the Restricted Shares maintain eligibility for the Performance-Based Exception.

8.7 TERMINATION OF EMPLOYMENT. Each Restricted Stock Award Agreement shall set forth the extent to which the Participant shall have the right to receive unvested Restricted Shares following termination of the Participant's employment with the Company and/or its Subsidiaries. Such provisions shall be determined in the sole discretion of the Committee, shall be included in the Award Agreement entered into with each Participant, need not be uniform among all Shares of Restricted Stock issued pursuant to the Plan, and may reflect distinctions based on the reasons for termination of employment; provided, however that, except in the cases of terminations connected with

72

a Change in Control, terminations by reason of death or Disability, and except for Restricted Shares paid to Participants upon SAR exercise, the vesting of Shares of Restricted Stock which qualify for the Performance-Based Exception and which are held by Named Executive Officers shall not occur prior to the time they otherwise would have, but for the employment termination.

ARTICLE 9. PERFORMANCE UNITS AND PERFORMANCE SHARES

9.1 GRANT OF PERFORMANCE UNITS/SHARES. Subject to the terms of the Plan, Performance Units and/or Performance Shares may be granted to Participants in such amounts and upon such terms, and at any time and from time to time, as shall be determined by the Committee.

9.2 VALUE OF PERFORMANCE UNITS/SHARES. Each Performance Unit shall have an initial value that is established by the Committee at the time of grant. Each Performance Share shall have an initial value equal to the Fair Market Value of a Share on the date of grant. The Committee shall set performance goals in its discretion which, depending on the extent to which they are met, will determine the number and/or value of Performance Units/Shares that will be paid out to the Participant. For purposes of this Article 9, the time period during which the performance goals must be met shall be called a "Performance Period."

9.3 EARNING OF PERFORMANCE UNITS/SHARES. Subject to the terms of this Plan, after the applicable Performance Period has ended, the holder of Performance Units/Shares shall be entitled to receive payout on the number and value of Performance Units/Shares earned by the Participant over the Performance Period, to be determined as a function of the extent to which the corresponding performance goals have been achieved, as established by the Committee.

9.4 FORM AND TIMING OF PAYMENT OF PERFORMANCE UNITS/SHARES. Payment of earned Performance Units/Shares shall be made in a single lump sum within seventy-five (75) calendar days following the close of the applicable Performance Period. Subject to the terms of this Plan, the Committee, in its sole discretion, may pay earned Performance Units/Shares in the form of cash or in Shares (or in a combination thereof) which have an aggregate Fair Market Value equal to the value of the earned Performance Units/Shares at the close of the applicable Performance Period. Such Shares may be granted subject to any restrictions deemed appropriate by the Committee.

73

At the discretion of the Committee, Participants may be entitled to receive any dividends declared with respect to Shares which have been earned in connection with grants of Performance Units and/or Performance Shares which have been earned, but not yet distributed to Participants (such dividends shall be subject to the same accrual, forfeiture, and payout restrictions as apply to dividends earned with respect to Shares of Restricted Stock, as set forth in
Section 8.6 herein). In addition, Participants may, at the discretion of the Committee, be entitled to exercise their voting rights with respect to such Shares.

9.5 TERMINATION OF EMPLOYMENT DUE TO DEATH, DISABILITY, OR RETIREMENT. Unless otherwise designated by the Committee, and set forth in the Participant's Award Agreement, in the event the employment of a Participant is terminated due to death, Disability, or Retirement during a Performance Period, the Participant shall receive a prorated payout of the Performance Units/Shares. The prorated payout shall be determined by the Committee, shall be based upon the length of time that the Participant held the Performance Units/Shares during the Performance Period, and shall further be adjusted based on the achievement of the preestablished performance goals.

Payment of earned Performance Units/Shares shall be made at a time specified by the Committee in its sole discretion and set forth in the Participant's Award Agreement. Notwithstanding the foregoing, with respect to Named Executive Officers who retire during a Performance Period, payments shall be made at the same time as payments are made to Participants who did not terminate employment during the applicable Performance Period.

9.6 TERMINATION OF EMPLOYMENT FOR OTHER REASONS. In the event that a Participant's employment terminates for any reason other than those reasons set forth in Section 9.5 herein, all Performance Units/Shares shall be forfeited by the Participant to the Company unless determined otherwise by the Committee, as set forth in the Participant's Award Agreement.

9.7 NONTRANSFERABILITY. Except as otherwise provided in a Participant's Award Agreement, Performance Units/Shares may not be sold, transferred, pledged, assigned, or otherwise alienated or hypothecated, other than by will or by the laws of descent and distribution. Further, except as otherwise provided in a Participant's Award Agreement, a Participant's rights under the Plan shall be exercisable during the Participant's lifetime only by the Participant or the Participant's legal representative.

74

ARTICLE 10. OTHER INCENTIVE AWARDS

10.1 GRANT OF OTHER INCENTIVE AWARDS. Subject to the terms and provisions of the Plan, Other Incentive Awards may be granted to Participants in such amount, upon such terms, and at any time and from time to time as shall be determined by the Committee.

10.2 OTHER INCENTIVE AWARD AGREEMENT. Each Other Incentive Award grant shall be evidenced by an Award Agreement that shall specify the amount of the Other Incentive Award granted, the terms and conditions applicable to such grant, the applicable Performance Period and performance goals, and such other provisions as the Committee shall determine, subject to the terms and provisions of the Plan.

10.3 NONTRANSFERABILITY. Except as otherwise provided in a Participant's Award Agreement, Other Incentive Awards may not be sold, transferred, pledged, assigned, or otherwise alienated or hypothecated, other than by will or by the laws of descent and distribution.

10.4 FORM AND TIMING OF PAYMENT OF OTHER INCENTIVE AWARDS. Payment of Other Incentive Awards shall be made at such times and in such form, in cash, in Shares, or in Restricted Shares (or a combination thereof), as established by the Committee subject to the terms of the Plan. Such Shares may be granted subject to any restrictions deemed appropriate by the Committee. Without limiting the generality of the foregoing, annual incentive awards may be paid in the form of Shares and/or Other Incentive Awards (which may or may not be subject to restrictions, at the discretion of the Committee).

ARTICLE 11. PERFORMANCE MEASURES

Unless and until the Committee proposes for shareholder vote and shareholders approve a change in the general performance measures set forth in this Article 11, the attainment of which may determine the degree of payout and/or vesting with respect to Awards to Named Executive Officers which are designed to qualify for the Performance-Based Exception, the performance measure(s) to be used for purposes of such grants shall be chosen from among the following alternatives, as reported on the Company's annual 10-k report:

(a) Return on Assets ("ROA") which equals net income divided by total assets.

(b) Return on Sales ("ROS") which equals net income divided by net sales.

75

(c) Return on Equity ("ROE") which equals net income divided by total equity.

(d) Cash Flow Return on Investment ("CFROI") which equals net cash flows divided by owners equity.

(e) Operating Income.

(f) Earnings Before Income Taxes ("EBIT") which equals net income plus taxes.

(g) Net Earnings which equals net earnings as reported.

(h) Earnings Per Share.

The Committee shall have the discretion to adjust the determinations of the degree of attainment of the preestablished performance goals; provided, however, that Awards which are designed to qualify for the Performance-Based Exception, and which are held by Named Executive Officers, may not be adjusted upward (the Committee shall retain the discretion to adjust such Awards downward).

In the event that applicable tax and/or securities laws change to permit Committee discretion to alter the governing performance measures without obtaining shareholder approval of such changes, the Committee shall have sole discretion to make such changes without obtaining shareholder approval. In addition, in the event that the Committee determines that it is advisable to grant Awards which shall not qualify for the Performance-Based Exception, the Committee may make such grants without satisfying the requirements of Code
Section 162(m) and, thus, which use performance measures other than those specified above. To the extent that the Committee determines that it is advisable to grant Awards in compliance with the Performance-Based Exception, the Committee must certify, in writing, prior to the payment of any compensation under the Award, that the performance goals and any other material terms were in fact satisfied.

ARTICLE 12. BENEFICIARY DESIGNATION

Each Participant under the Plan may, from time to time, name any beneficiary or beneficiaries (who may be named contingently or successively) to whom any benefit under the Plan is to be paid in case of his or her death before he or she receives any or all of such benefit. Each such designation shall revoke all prior designations by the same Participant, shall be in a form

76

prescribed by the Company, and will be effective only when filed by the Participant in writing with the Company during the Participant's lifetime. In the absence of any such designation, benefits remaining unpaid at the Participant's death shall be paid to the Participant's estate.

ARTICLE 13. DEFERRALS

The Committee may permit a Participant to defer such Participant's receipt of the payment of cash or the delivery of Shares that would otherwise be due to such Participant by virtue of the exercise of an Option or SAR, the lapse or waiver of restrictions with respect to Restricted Stock, or the satisfaction of any requirements or goals with respect to Performance Units/Shares or Other Incentive Awards. If any such deferral election is required or permitted, the Committee shall, in its sole discretion, establish rules and procedures for such payment deferrals.

ARTICLE 14. RIGHTS OF EMPLOYEES

14.1 EMPLOYMENT. Nothing in the Plan shall interfere with or limit in any way the right of the Company to terminate any Participant's employment at any time, nor confer upon any Participant any right to continue in the employ of the Company.

14.2 PARTICIPATION. No Employee shall have the right to be selected to receive an Award under this Plan, or, having been so selected, to be selected to receive a future Award.

ARTICLE 15. CHANGE IN CONTROL

15.1 TREATMENT OF OUTSTANDING AWARDS. Upon the occurrence of a Change in Control, unless otherwise specifically prohibited under applicable laws, or by the rules and regulations of any governing governmental agencies or national securities exchanges:

(a) Any and all Options, Director Options and SARs granted hereunder shall become immediately exercisable, and shall remain exercisable throughout their entire term, and any cash or property received upon exercise of any Option or SAR shall be free from further restriction;

(b) Any restriction periods and restrictions imposed on Restricted Shares shall lapse; and

77

(c) Unless otherwise specified in Participant's Award Agreement at time of grant, the target payout opportunities attainable under all outstanding Awards of Performance Units and Performance Shares and Other Incentive Awards shall be deemed to have been fully earned for the entire Performance Period(s) as of the effective date of the Change in Control. The vesting of all such Awards shall be accelerated as of the effective date of the Change in Control, and in full settlement of such Awards, there shall be paid out to Participants (in Shares for Awards normally paid in Shares and in cash for Awards normally paid in cash) within thirty
(30) days following the effective date of the Change in Control a pro rata portion of all targeted Award opportunities associated with such outstanding Awards, based on the number of complete and partial calendar months within the Performance Period which had elapsed as of such effective date.

15.2 TERMINATION, AMENDMENT, AND MODIFICATIONS OF CHANGE-IN-CONTROL PROVISIONS. Notwithstanding any other provision of this Plan or any Award Agreement provision, the provisions of this Article 15 may not be terminated, amended, or modified to affect adversely any Award or Director Option theretofore granted under the Plan without the prior written consent of the Participant or Eligible Director with respect to said Participant's or Eligible Director's outstanding Awards or Director Options.

ARTICLE 16. AMENDMENT, MODIFICATION, AND TERMINATION

16.1 AMENDMENT, MODIFICATION, AND TERMINATION. The Board may at any time and from time to time alter, amend, suspend or terminate the Plan in whole or in part, provided that no amendment may be made to Section 6.9 or any other provision of the Plan relating to Director Options within six months of the last date on which any such provision was amended, other than to comport with changes in the Code or the rules thereunder. The Committee shall not have the authority to cancel outstanding Awards and issue substitute Awards in replacement thereof.

16.2 AWARDS PREVIOUSLY GRANTED. No termination, amendment, or modification of the Plan shall adversely affect in any material way any Award previously granted under the Plan, without the written consent of the Participant holding such Award.

16.3 COMPLIANCE WITH CODE SECTION 162(m). At all times when Code
Section 162(m) is applicable, all Awards granted under this Plan shall comply with the requirements of Code Section

78

162(m); provided, however, that in the event the Committee determines that such compliance is not desired with respect to any Award or Awards available for grant under the Plan, then compliance with Code Section 162(m) will not be required. In addition, in the event that changes are made to Code Section 162(m) to permit greater flexibility with respect to any Award or Awards available under the Plan, the Committee may, subject to this Article 16, make any adjustments it deems appropriate.

ARTICLE 17. WITHHOLDING

17.1 TAX WITHHOLDING. The Company shall have the power and the right to deduct or withhold, or require a Participant or Eligible Director to remit to the Company, an amount sufficient to satisfy federal, state, and local taxes, domestic or foreign, required by law or regulation to be withheld with respect to any taxable event arising as a result of this Plan.

17.2 SHARE WITHHOLDING. With respect to withholding required upon the exercise of Options, Director Options or SARs, upon the lapse of restrictions on Restricted Stock, or upon any other taxable event arising as a result of Awards granted hereunder, Participants or Eligible Directors may elect, subject to the approval of the Committee, to satisfy the withholding requirement, in whole or in part, by having the Company withhold Shares having a Fair Market Value on the date the tax is to be determined equal to the minimum statutory total tax which could be imposed on the transaction. All such elections shall be irrevocable, made in writing, signed by the Participant or Eligible Director, and shall be subject to any restrictions or limitations that the Committee, in its sole discretion, deems appropriate.

ARTICLE 18. INDEMNIFICATION

Each person who is or shall have been a member of the Committee, or of the Board, shall be indemnified by the Company against and from any loss, cost, liability, or expense that may be imposed upon or reasonably incurred by him or her in connection with or resulting from any claim, action, suit, or proceeding to which he or she may be a party or in which he or she may be involved by reason of any action taken or failure to act under the Plan. Such person shall be indemnified by the Company for all amounts paid by him or her in settlement thereof, with the Company's approval, or paid by him or her in satisfaction of any judgment in any such action, suit, or proceeding against him or her, provided he or she shall give the Company an opportunity, at its own expense, to handle and defend

79

the same before he or she undertakes to handle and defend it on his or her own behalf. The foregoing right of indemnification shall not be exclusive of any other rights of indemnification to which such persons may be entitled under the Company's Articles of Incorporation or Bylaws, as a matter of law, or otherwise, or any power that the Company may have to indemnify them or hold them harmless.

ARTICLE 19. SUCCESSORS

All obligations of the Company under the Plan with respect to Awards or Director Options granted hereunder shall be binding on any successor to the Company, whether the existence of such successor is the result of a direct or indirect purchase, merger, consolidation, or otherwise, of all or substantially all of the business and/or assets of the Company.

20.3 REQUIREMENTS OF LAW. The granting of Awards or Director Options and the issuance of Shares under the Plan shall be subject to all applicable laws, rules, and regulations, and to such approvals by any governmental agencies or national securities exchanges as may be required.

20.4 GOVERNING LAW. To the extent not preempted by federal law, the Plan, and all agreements hereunder, shall be construed in accordance with and governed by the laws of the State of Delaware.

Exhibit 5

Opinion of Vorys, Sater, Seymour and Pease, Counsel to Registrant

(614) 464-6400

June 13, 1997

Board of Directors
Core Materials Corporation
800 Manor Park Drive
P.O. Box 28183
Columbus, Ohio 43228-0183

Gentlemen:

We are familiar with the proceedings taken and proposed to be taken by Core Materials Corporation (the "Company") in connection with the registration for issuance and sale of shares of common stock of the Company, par value $.01 per share, (the "Common Stock") under the Company's Long-Term Equity Incentive Plan (the "Plan"), as described in the Registration Statement on Form S-8 (the "Registration Statement") to be filed with the Securities and Exchange Commission on or about June 13, 1997. The purpose of the Registration Statement is to register an additional 1,500,000 shares of Common Stock reserved for issuance under the Plan pursuant to the provisions of the Securities Act of 1933, as amended, and the rules and regulations promulgated thereunder.

In connection with this opinion, we have examined an original or copy of, and have relied upon the accuracy of, without independent verification or investigation: (a) the Registration Statement; (b) the Plan;
(c) the Certificate of Incorporation of the Company, as amended through November 6, 1996; (d) the By-Laws of the Company; and (e) certain proceedings of the directors and of the stockholders of the Company. We have also relied upon such representations of the Company and officers of the Company and such authorities of law as we have deemed relevant as a basis for this opinion.

We have relied solely upon the examinations and inquiries recited herein, and we have not undertaken any independent investigation to determine the existence or absence

of any facts, and no inference as to our knowledge concerning such facts should be drawn.

Based upon and subject to the foregoing and the further qualifications and limitations set forth below, as of the date hereof, we are of the opinion that after the 1,500,000 shares of Common Stock of the Company to be registered under the Registration Statement have been issued and delivered by the Company upon the exercise of options under the Plan against payment of the purchase price therefor, against settlement of Performance Awards granted under the Plan, upon the exercise of Stock Appreciation Rights under the Plan, and upon grant of Restricted Stock under the Plan, in each case in accordance with the terms of the Plan, said shares of Common Stock will be validly issued, fully paid and non-assessable, assuming compliance with applicable federal and state securities laws and with the transfer restrictions contained in the Company's Certificate of Incorporation, as amended through November 6, 1996.

Our opinion is limited to the General Corporation Law of Delaware in effect as of the date hereof. This opinion is furnished by us solely for the benefit of the Company in connection with the offering of the shares of Common Stock pursuant to the Plan and the filing of the Registration Statement and any amendments thereto. This opinion may not be relied upon by any other person or assigned, quoted or otherwise used without our specific written consent.

Notwithstanding the foregoing, we consent to the filing of this opinion as an exhibit to the Registration Statement and to the reference to us therein.

Very truly yours,
