1. BACKGROUND AND BASIS OF PRESENTATION

We believe we are the leading supplier of high-performance polishing slurries used in the manufacture of the most advanced integrated circuit ("IC") devices within the semiconductor industry, in a process called chemical mechanical planarization ("CMP"). CMP is a polishing process used by IC device manufacturers to planarize or flatten many of the multiple layers of material that are built upon silicon wafers, and is a necessary step in the production of advanced ICs. Planarization is a polishing process that uses CMP slurries and pads to level, smooth and remove excess material from the surfaces of these layers. CMP slurries are liquid formulations that facilitate and enhance this polishing process and generally contain engineered abrasives and proprietary chemicals. CMP pads are typically flat engineered "disks" that help distribute and transport the slurry to the surface of the wafer and across the wafer.

Cabot Microelectronics, which was incorporated in October 1999 and formed from the assets of Cabot Corporation's Microelectronics Materials Division, completed its initial public offering in April 2000. In September 2000 we became a wholly independent entity upon Cabot Corporation's spin-off of its remaining ownership ("spin-off") in our company by its distribution of 0.280473721 shares of Cabot Microelectronics common stock as a dividend on each share of Cabot Corporation common stock.

The unaudited consolidated financial statements have been prepared by Cabot Microelectronics Corporation ("Cabot Microelectronics", "the Company", "us", "we", or "our"), pursuant to the rules of the Securities and Exchange Commission ("SEC") and accounting principles generally accepted in the United States of America. In the opinion of management, these unaudited consolidated financial statements include all adjustments necessary for the fair presentation of Cabot Microelectronics' financial position as of December 31, 2003, cash flows for the three months ended December 31, 2003 and December 31, 2002 and results of operations for the three months ended December 31, 2003 and December 31, 2002. The results of operations for the three months ended December 31, 2003 may not be indicative of the results to be expected for future periods, including the fiscal year ending September 30, 2004. These unaudited consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes thereto included in Cabot Microelectronics' Annual Report on Form 10-K for the fiscal year ended September 30, 2003. We operate predominantly in one industry segment - the development, manufacture, and sale of CMP slurries.

The consolidated financial statements include the accounts of Cabot Microelectronics and its subsidiaries. All intercompany transactions and balances between the companies have been eliminated.

2. STOCK-BASED COMPENSATION

In December 2002 we adopted the disclosure requirements of SFAS No. 148, "Accounting for Stock-Based Compensation - Transition and Disclosure" ("SFAS 148"). SFAS 148 amends FASB Statement No. 123, "Accounting for Stock-Based Compensation" ("SFAS 123"), to provide alternative methods of transition for a voluntary change to the fair value based method of accounting for stock-based compensation and also amends the disclosure requirements of SFAS 123 to require prominent disclosures in both annual and interim financial statements about the methods of accounting for stock-based employee compensation and the effect of the method used on reported results. As permitted by SFAS 148 and SFAS 123, we continue to apply the accounting provisions of Accounting Principles Board ("APB") Opinion Number 25, "Accounting for Stock Issued to Employees", and related interpretations, with regard to the measurement of compensation cost for options granted under our Equity Incentive Plan and shares issued under our Employee Stock Purchase Plan. No employee compensation expense has been recorded as all options granted had an exercise price equal to the market value of the underlying common stock on the date of grant. Had expense been recognized using the fair value method described in

8. CONTINGENCIES

LEGAL PROCEEDINGS

We periodically become subject to legal proceedings in the ordinary course of business. We are not currently involved in any legal proceedings that we believe will have a material impact on our consolidated financial position, results of operations, or cash flows.

PRODUCT WARRANTIES

We record warranty expense in cost of goods sold in the period in which the warranty claims occur. We calculate our warranty reserve shown below using historical experience and any known conditions or circumstances, and we perform periodic reviews of our warranty reserve requirements and make appropriate adjustments to the reserve as necessary. Our warranty obligation is affected primarily by product that does not meet specifications or performance requirements and any related costs of addressing such matters. Our warranty reserve requirements increased during the first fiscal quarter of 2004 as follows:

Balance as of September 30, 2003........  $       836
Net change..............................          601

                                          ===========

INDEMNIFICATION DISCLOSURE

In the normal course of business, we are a party to a variety of agreements pursuant to which we may be obligated to indemnify the other party with respect to certain matters. Generally, these obligations arise in the context of agreements entered into by us, under which we customarily agree to hold the other party harmless against losses arising from a breach of representations and covenants related to such matters as title to assets sold, certain intellectual property rights and, in certain circumstances, specified environmental matters. These terms are common in the industry in which we conduct business. In each of these circumstances, payment by us is subject to certain monetary and other limitations and is conditioned on the other party making an adverse claim pursuant to the procedures specified in the particular agreement, which typically allow us to challenge the other party's claims.

CABOT MICROELECTRONICS CORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED)
(UNAUDITED AND IN THOUSANDS, EXCEPT SHARE AND PER SHARE AMOUNTS)

We evaluate estimated losses for such indemnifications under SFAS No. 5, "Accounting for Contingencies" as interpreted by FASB Interpretation No. 45, "Guarantor's Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others" ("FIN 45"). We consider such factors as the degree of probability of an unfavorable outcome and the ability to make a reasonable estimate of the amount of loss. To date, we have not encountered material costs as a result of such obligations and as of December 31, 2003, have not recorded any liabilities related to such indemnifications in our financial statements as we do not believe the likelihood of a material obligation is probable.

9. EFFECTS OF RECENT ACCOUNTING PRONOUNCEMENTS

In April 2003, the FASB issued SFAS No. 149, "Amendment of Statement 133 on Derivative Instruments and Hedging Activities" ("SFAS 149") which applies to contracts entered into or modified after June 30, 2003. SFAS 149 amends and clarifies accounting for derivative instruments, including certain derivative instruments embedded in other contracts, and for hedging activities under SFAS 133, "Accounting for Derivative Instruments and Hedging Activities." The adoption of SFAS 149 has not had a material impact on our consolidated financial position, results of operations or cash flows, and we do not expect it to have a material impact in the future.

In December 2003, the Staff of the Securities and Exchange Commission ("SEC") issued Staff Accounting Bulletin No. 104, "Revenue Recognition" ("SAB 104") which supercedes Staff Accounting Bulletin No. 101, "Revenue Recognition in Financial Statements" ("SAB 101"). The primary purpose of SAB 104 is to rescind accounting guidance contained in SAB 101 related to multiple element revenue arrangements, superceded as a result of the issuance of Emerging Issue Task Force Issue No. 00-21, "Accounting for Revenue Arrangements with Multiple Deliverables" ("EITF 00-21"). Additionally, SAB 104 rescinds the SEC's "Revenue Recognition in Financial Statements Frequently Asked Questions and Answers" ("the FAQ") issued with SAB 101 that had been codified in SEC Topic 13, "Revenue Recognition". Selected portions of the FAQ have been incorporated into SAB 104. While the wording of SAB 104 reflects the issuance of EITF 00-21, the revenue recognition principles of SAB 101 remain largely unchanged by the issuance of SAB 104. The adoption of SAB 104 did not impact our consolidated financial position, results of operations or cash flow.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following "Management's Discussion and Analysis of Financial Condition and Results of Operations", as well as disclosures included elsewhere in this Form 10-Q, include "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995. This Act provides a "safe harbor" for forward-looking statements to encourage companies to provide prospective information about themselves so long as they identify these statements as forward-looking and provide meaningful cautionary statements identifying important factors that could cause actual results to differ from the projected results. All statements other than statements of historical fact we make in this Form 10-Q are forward-looking. In particular, the statements herein regarding industry or general economic prospects or trends, our future results of operations or financial position and statements preceded by, followed by or that include the words "intends", "estimates", "plans", "believes", "expects", "anticipates", "should", "could", or similar expressions, are forward-looking statements. Forward-looking statements reflect our current expectations and are inherently uncertain. Our actual results may differ significantly from our expectations. We assume no obligation to update this forward-looking information. The section entitled "Factors Affecting Future Operating Results" describes some, but not all, of the factors that could cause these differences. This section, "Management's Discussion and Analysis of Financial Condition and Results of Operations", should be read in conjunction with the consolidated financial statements and related notes thereto included in Cabot Microelectronics' Annual Report on Form 10-K for the fiscal year ended September 30, 2003.

FIRST FISCAL QUARTER OVERVIEW

We believe we are the leading supplier of high-performance polishing slurries used in the manufacture of the most advanced integrated circuit ("IC") devices within the semiconductor industry, in a process called chemical mechanical planarization ("CMP"). We develop, produce and sell CMP slurries for polishing copper, tungsten and oxide in IC devices, and also for polishing magnetic heads and the coating on disks in hard disk drives. We are currently operating as a value-added reseller of CMP polishing pads produced by a third party and are also developing our own pad technologies.

Our first quarter revenue of $76.3 million grew from the previous fiscal quarter by 12.3%, and by 33.2% compared to the same quarter in the last fiscal year. We believe this revenue growth, along with other signs we see in the industry, is evidence of a recovery from the sustained semiconductor industry downturn. Net income grew by 20.2% from the previous fiscal quarter and by 25.1% from the same quarter last fiscal year. Our gross margin percentage of 48.8% of revenue was lower than in the previous quarter and the first quarter of fiscal 2003, due to higher costs related to lower yields in our manufacturing process, increased product warranty costs and higher freight costs. These higher costs were required to meet our customers' increased demands for higher product quality and consistency. We expect gross profit as a percentage of revenue to be in the range of 50%, plus or minus 2%, in fiscal 2004. We anticipate that from time to time we may experience periods of higher manufacturing costs, as we did this quarter, and as we previously experienced in other periods, such as the second quarter of fiscal 2003, due to more strenuous product requirements from our customers. During the quarter, we entered into an amended and restated unsecured revolving credit facility of $50.0 million with an option to increase the facility by up to $30.0 million. This agreement replaces our $75.0 million unsecured revolving credit and term loan facility that we entered into in July 2001.

We anticipate the worldwide market for CMP consumables used by IC device manufacturers will grow in the future as a result of expected increases in the number of IC devices produced, the percentage of IC devices produced that require CMP and the number of CMP polishing steps used to produce these devices. In addition, we believe that technology advances will require the use of new materials in IC device manufacture that will require new CMP solutions. We expect this anticipated growth will be mitigated somewhat by efficiencies in CMP slurry and pad usage such as IC device manufacturers moving from 200 mm to 300 mm wafers. We are aware of several other manufacturers of CMP consumables with sales of CMP slurries for IC devices and, due to the attractive growth outlook for CMP, we expect competition will continue to increase as other companies attempt to enter this market.

In November 2003 we announced the election of William P. Noglows as Chairman, President and Chief Executive Officer, following the resignation of Matthew Neville from these positions and from the board of directors. Mr. Noglows previously served as an outside director of our company from 2000 until 2002 and is a 23-year veteran executive of the specialty chemical industry, with an emphasis on highly engineered performance materials for the semiconductor and electronics industries. In December 2003, we announced that Clifford L. Spiro had joined us as our Vice President, Research and Development. We also made certain other changes within our management team to strengthen our focus on the Asia Pacific region, and on corporate strategy and development. We continue to focus on three key strategies; remaining the technology leader in CMP slurries, achieving operations excellence through improved product quality and consistency, and building and maintaining close customer relationships.

RESULTS OF OPERATIONS

THREE MONTHS ENDED DECEMBER 31, 2003 VERSUS THREE MONTHS ENDED DECEMBER 31, 2002

REVENUE

Total revenue was $76.3 million for the three months ended December 31, 2003, which represented a 33.2%, or $19.0 million, increase from the three months ended December 31, 2002. Of this increase, $17.4 million was due to an increase in sales volume and $1.6 million from an increase in weighted average selling prices. Revenue in the year ago quarter was

11

depressed as the semiconductor industry experienced a fall off in business as the perceived industry recovery was not sustained following stronger performance in the June and September quarters of 2002. Copper product revenue increased 29.0% over the prior year quarter and tungsten and dielectric product revenues combined increased by 37.5%. Revenue would have been $1.5 million lower had the Japanese Yen and Euro average exchange rate for the quarter held constant with the prior year's first fiscal quarter average.

COST OF GOODS SOLD

Total cost of goods sold was $39.0 million for the three months ended December 31, 2003, which represented an increase of 41.1% or $11.4 million from the three months ended December 31, 2002. Of this increase, $8.4 million was due to an increase in volume and $3.0 million from higher costs. These higher costs were related primarily to lower yields in our manufacturing process, increased product warranty costs and higher freight costs required to meet our customers' increased demand for product quality and consistency. From time to time we may experience similar periods of higher manufacturing costs in the future as we continue to respond to our customers' more strenuous requirements.

Fumed metal oxides, both fumed silica and fumed alumina, are significant raw materials we use in many of our CMP slurries. From the time of our initial public offering in April 2000 to January 2004, we purchased fumed silica and fumed alumina under a fumed metal oxide agreement with Cabot Corporation that was due to expire June 2005. In January 2004 we entered into a fumed silica supply agreement with Cabot Corporation, which replaces the original fumed metal oxide agreement with respect to fumed silica, and accordingly amended our fumed metal oxide agreement with respect to its fumed silica terms such that the agreement now only applies to fumed alumina and runs through June 2005. This fumed silica supply agreement provides for improved supply assurance, reduces our risk to rising raw material costs and implements improved quality performance measures and requirements that support our initiative to increase product quality and consistency. The contract provides for the cost of fumed silica to increase approximately 4% over the initial term of the fumed silica supply agreement, subject to inflation adjustments and shared cost savings adjustments resulting from our joint efforts. This agreement has an initial six-year term, which expires in December 2009 and will automatically renew unless either party gives certain notice of non-renewal.

In addition, since December 2001, we have operated under a fumed alumina supply agreement with Cabot Corporation under which Cabot Corporation expanded its capacity for the manufacture of fumed alumina and we have the first right to all this expanded capacity. The agreement provides that the price Cabot Corporation charges us for fumed alumina is based on all of its fixed and variable costs for producing the fumed alumina, plus its capital costs for expanding its capacity, plus an agreed upon rate of return on investment, plus incentive payments if they produce more than a certain amount per year that meets our specifications.

Our need for additional quantities or different kinds of key raw materials in the future has required and will continue to require that we enter into new supply arrangements with third parties. Future arrangements may result in costs which are higher than those in the existing agreements.

GROSS PROFIT

Our gross profit as a percentage of total revenue was 48.8%, for the three months ended December 31, 2003 as compared to 51.7% for the three months ended December 31, 2002. The decrease in gross profit expressed as a percentage of total revenue resulted primarily from an increase in production and warranty costs associated with increased product performance requirements of our customers. We expect our gross profit as a percentage of total revenue in fiscal year 2004 to be in the range of 50%, plus or minus 2%.

12

RESEARCH AND DEVELOPMENT

Research and development expenses were $10.7 million in the three months ended December 31, 2003, which represented an increase of 24.2%, or $2.1 million, from the three months ended December 31, 2002. Research and development expense increased $1.1 million due to increased staffing, $0.4 due to higher technical service and consulting fees, $0.3 million due to higher supplies and $0.2 million due to higher depreciation related to the purchase of equipment for our CMP polishing and metrology clean room. R&D efforts were mainly related to new and enhanced CMP products including slurry products for copper applications, new CMP polishing pad technology and advanced chemistry and particle technology.

SELLING AND MARKETING

Selling and marketing expenses were $3.8 million in the three months ended December 31, 2003, which represented an increase of 46.7%, or $1.2 million, from the three months ended December 31, 2002. The increase resulted primarily from higher staffing costs associated with our increased customer support initiatives including our transition to selling direct to customers in Europe, Singapore, Malaysia and Japan, rather than through a distributor.

GENERAL AND ADMINISTRATIVE

General and administrative expenses were $5.1 million in the three months ended December 31, 2003, which represented an increase of 17.3%, or $0.8 million, from the three months ended December 31, 2002. The increase resulted from a $0.2 million increase in staffing, $0.2 million of costs associated with the transition to our new chief executive officer, $0.2 million related to higher insurance premiums and increased professional fees of $0.1 million.

AMORTIZATION OF INTANGIBLES

Amortization of intangibles was $0.1 million for both the three months ended December 31, 2003 and 2002.

OTHER INCOME (EXPENSE), NET

Other income (expense), net was negligible for both the three months ended December 31, 2003 and 2002.

PROVISION FOR INCOME TAXES

The effective income tax rate was 34.0% for the three months ended December 31, 2003 and 33.5% for the three months ended December 31, 2002. The increase in the effective tax rate was due to the anticipated June 2004 expiration of the current tax legislation related to research and experimentation credits and the decreased impact of these credits in relation to higher taxable income as compared to the prior year. We expect our income tax rate for full fiscal year 2004 to be 34.0%.

NET INCOME

Net income was $11.6 million for the three months ended December 31, 2003, which represented an increase of 25.1%, or $2.3 million, from the three months ended December 31, 2002 as a result of the factors discussed above.

13

LIQUIDITY AND CAPITAL RESOURCES

We had cash flows from operating activities of $16.5 million in the three months ended December 31, 2003 and $7.7 million in the three months ended December 31, 2002. Our cash provided by operating activities for the three months ended December 31, 2003 originated from net income from operations of $11.6 million and non-cash items of $4.9 million.

In the three months ended December 31, 2003, capital spending was $1.3 million, primarily related to tools and equipment for our CMP polishing and metrology cleanroom. Full fiscal year 2004 capital spending and depreciation expense are anticipated to be approximately $22.0 million and $19.4 million, respectively. In the three months ended December 31, 2002, capital spending was $2.3 million, primarily for manufacturing equipment for the production of new products and additional research and development equipment.

Cash flows from financing activities were $0.8 million in the three months ended December 31, 2003 and $1.7 million in the three months ended December 31, 2002. Cash provided from financing activities for both periods resulted from the issuance of common stock associated with the exercise of stock options, which was partially offset by principal payments made under capital lease obligations.

In July 2001 we entered into a $75.0 million unsecured revolving credit and term loan facility with a group of commercial banks, and in February 2002 and August 2003 this agreement was amended with no material changes in terms. On November 24, 2003 the existing agreement was terminated and replaced with an amended and restated unsecured revolving credit facility of $50.0 million with an option to increase the facility by up to $30.0 million. Under this agreement, which terminates in November 2006, but can be renewed for two one year terms, interest accrues on any outstanding balance at either the institution's base rate or the eurodollar rate plus an applicable margin. A non-use fee also accrues. Loans under this facility are anticipated to be used primarily for general corporate purposes, including working capital and capital expenditures. The credit agreement also contains various covenants. No amounts are currently outstanding under this credit facility and we believe we are currently in compliance with the covenants.

We believe that cash generated by our operations and available borrowings under our revolving credit facility will be sufficient to fund our operations and expected capital expenditures for the foreseeable future. However, we plan to expand our business and continue to improve our technology and, to do so, we may be required to raise additional funds in the future through public or private equity or debt financing, strategic relationships or other arrangements.

OFF-BALANCE SHEET ARRANGEMENTS

At December 31, 2003 and September 30, 2003, we did not have any unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities, which might have been established for the purpose of facilitating off-balance sheet arrangements.

TABULAR DISCLOSURE OF CONTRACTUAL OBLIGATIONS

The following summarizes our contractual obligations at December 31, 2003 and the effect such obligations are expected to have on our liquidity and cash flow in future periods.

CAPITAL LEASE OBLIGATIONS

Since December 2001 we have operated under a fumed alumina supply agreement with Cabot Corporation, under which Cabot Corporation expanded its capacity in Tuscola, Illinois for the manufacture of fumed alumina. Payments by us with respect to capital costs for the facility have been treated as a capital lease for accounting purposes and the present value of the minimum quarterly payments of approximately $0.3 million resulted in a $9.8 million lease obligation and $9.8 million related leased asset. The agreement has an initial five-year term, which expires in 2006, but we can choose to renew the agreement for another five-year term, which would expire in 2011. We also can choose to not renew the agreement subject to certain terms and conditions and the payment of certain costs, after the initial five-year term.

In January 2002 we entered into a CMP tool and polishing consumables transfer agreement with a third party under which we agreed to transfer polishing consumables to this entity in return for a CMP polishing tool. The polishing tool has been treated as a capital lease and the aggregate fair market value of the polishing consumables resulted in a $2.0 million lease obligation. The term of the agreement is approximately three years, expiring in November 2004.

OPERATING LEASES

We lease certain vehicles, warehouse facilities, office space, machinery and equipment under cancelable and noncancelable operating leases, most of which expire within ten years and may be renewed by us.

PURCHASE OBLIGATIONS

Purchase obligations include our take-or-pay arrangements with suppliers, and purchase orders and other obligations entered into in the normal course of business regarding the purchase of goods and services. In the fourth quarter of fiscal 2003, we recorded a $2.0 million liability for a raw material supply agreement for a polishing pad technology that was previously under development, but is no longer being pursued. Our total obligation with respect to this agreement is $2.2 million, of which $1.1 million is recorded in current liabilities and shown in the preceding table under purchase obligations and $1.1 million is included in other long-term liabilities, which is discussed below.

From the time of our initial public offering in April 2000 to January 2004, we purchased fumed silica and fumed alumina under a fumed metal oxide agreement with Cabot Corporation that was due to expire June 2005. Under this agreement, we were obligated to purchase at least 90% of our six-month volume forecast of fumed silica from Cabot Corporation and were obligated to pay for the shortfall if we purchased less than that amount. In January 2004 we entered into a fumed silica supply agreement with Cabot Corporation, which replaces the original fumed metal oxide agreement with respect to fumed silica, and accordingly amended our fumed metal oxide agreement with respect to its fumed silica terms such that the agreement now only applies to fumed alumina through June 2005. Under the fumed silica supply agreement, we continue to be obligated to purchase at least 90% of our six-month volume forecast and to pay for the shortfall if we purchase less than that amount. This agreement has an initial six-year term, which expires in December 2009 and will automatically renew unless either party gives certain notice of non-renewal. We currently anticipate meeting minimum forecasted purchase volume requirements. Also, under our fumed alumina supply agreement with Cabot Corporation we are obligated to pay certain fixed, capital and variable costs through December 2006. This agreement has an initial five-year term, but we can choose to renew the agreement for another five-year term, which would expire in December 2011. If we do not renew the agreement, we will become subject to certain terms and conditions and the payment of certain costs. Purchase obligations include $33.1 million of contractual commitments based upon our anticipated renewal of the agreement through December 2011.

We have an agreement with a toll manufacturer pursuant to which the manufacturer performs certain agreed-upon dispersion services. We have agreed to purchase minimum amounts of services per year and to invest approximately $0.2 million per year in capital improvements or other expenditures to maintain capacity at the manufacturer's dispersion facility. The initial term of the agreement expires in October 2004, with automatic one-year renewals, and contains a 90-

15

day cancellation clause executable by either party. Purchase obligations related to this agreement are $13.6 million, which include a termination payment if the agreement is not renewed.

We have a distribution agreement with an existing supplier of polishing pads to the semiconductor industry pursuant to which the supplier sells product to us for our resale to end users. The initial term of the contract runs through September 2007 and we are required to make certain agreed-upon payments in order to maintain the agreement. Included in purchase obligations is $5.0 million which we intend to pay by September 2004. We have the ability to cancel the agreement at any time with no cancellation fee.

In June 2003 we entered into a technology licensing and co-marketing agreement with a semiconductor equipment manufacturer under which we plan to develop, manufacture and sell polishing pads utilizing endpoint detection window technology licensed from the manufacturer for use on the manufacturer's equipment. Under this agreement, we are obligated to pay $6.6 million, of which $5.1 million has been paid as of December 31, 2003, for the purchase of capital equipment, approximately one year of certain marketing and technical support services, and equipment services. In addition, we are obligated to supply this manufacturer with free polishing pads, up to an agreed upon dollar amount, for particular uses over a seven year period. We currently estimate our total cost associated with these products will be $2.1 million over the remaining period. We are also obligated to supply the equipment manufacturer with polishing pads, up to an agreed upon dollar amount over the seven year period, which the manufacturer will purchase from us at our cost. We will also pay a royalty to the equipment manufacturer and, in certain circumstances, to another party to whom we are a sub-licensee under our agreement, based upon net revenue earned with respect to commercial sales of polishing pads covered under the agreement. The agreement's term lasts as long as the patents on the technology subject to the license agreement remain valid and enforceable.

OTHER LONG-TERM LIABILITIES

Other long-term liabilities include the $1.1 million long-term portion of the purchase obligation discussed above, that we recorded for a raw material supply agreement for a polishing pad technology that was previously under development, but is no longer being pursued. Also included is $1.1 million for pension and deferred compensation obligations.

FACTORS AFFECTING FUTURE OPERATING RESULTS

RISKS RELATING TO OUR BUSINESS

WE HAVE A NARROW PRODUCT RANGE AND OUR PRODUCTS MAY BECOME OBSOLETE, OR TECHNOLOGICAL CHANGES MAY REDUCE OR LIMIT INCREASES IN CMP CONSUMPTION

Our business is substantially dependent on a single class of products, CMP slurries, which historically has accounted for almost all of our revenue. Our business would suffer if these products became obsolete or if consumption of these products decreased. Our success depends on our ability to keep pace with technological changes and advances in the semiconductor industry and to adapt and improve our products in response to evolving customer needs and industry trends. Since its inception, the semiconductor industry has experienced rapid technological changes and advances in the design, manufacture, performance and application of IC devices and these changes and advances, including 300 mm wafers, are expected to continue in the future. Developments in the semiconductor industry could render our products obsolete or less important to the IC device manufacturing process.

A SIGNIFICANT AMOUNT OF OUR BUSINESS COMES FROM A LIMITED NUMBER OF LARGE CUSTOMERS AND OUR REVENUE AND PROFITS COULD DECREASE SIGNIFICANTLY IF WE LOST ONE OR MORE OF THEM AS CUSTOMERS

Our customer base is concentrated among a limited number of large customers. One or more of these principal customers may stop buying CMP slurries from us or may substantially reduce the quantity of CMP slurries they purchase from us. They also

16

hold considerable purchasing power, which can impact the pricing, and terms of sale of our products. Any cancellation, deferral or significant reduction in CMP slurries sold to these principal customers or a significant number of smaller customers could seriously harm our business, financial condition and results of operations. Our five largest customers, of which one is a distributor, accounted for approximately 54% of our revenue for the three months ended December 31, 2003. For the three months ended December 31, 2002 our five largest customers, of which two were distributors, accounted for approximately 59% of our revenue. In June 2003, we completed our transition to selling directly to customers in Europe, Singapore and Malaysia who previously had been serviced through one of these distributors.

ANY PROBLEM OR INTERRUPTION IN SUPPLY OF OUR MOST IMPORTANT RAW MATERIALS, INCLUDING FUMED METAL OXIDES, COULD DELAY OUR SLURRY PRODUCTION AND ADVERSELY AFFECT OUR SALES

Fumed metal oxides, both fumed silica and fumed alumina, are significant raw materials we use in many of our CMP slurries. Our business would suffer from any problem or interruption in our supply of fumed metal oxides or other key raw materials. We operate under three raw material supply agreements with Cabot Corporation, one of which for the supply of fumed silica and two of which for the supply of fumed alumina. Under these agreements, Cabot Corporation continues to be our primary supplier of particular amounts and types of fumed alumina and fumed silica. We believe it would be difficult to secure alternative sources of fumed metal oxides in the event Cabot Corporation or another supplier were unable to supply us with sufficient quantities of fumed metal oxides which meet the quality and technical specifications required by our customers. In addition, contractual amendments to the existing agreements with, or non-performance by, Cabot Corporation or another supplier, could adversely affect us as well.

In addition, if we change the supplier or type of key raw materials such as fumed metal oxides we use to make our existing CMP slurries or are required to purchase them from a different manufacturer or manufacturing facility, whether Cabot Corporation or another party, or otherwise modify our products, in certain circumstances our customers might have to requalify our CMP slurries for their manufacturing processes and products. The requalification process could take a significant amount of time to complete, possibly interrupting or reducing our sales of CMP slurries to these customers.

OUR BUSINESS COULD BE SERIOUSLY HARMED IF OUR EXISTING OR FUTURE COMPETITORS DEVELOP SUPERIOR SLURRY PRODUCTS, OFFER BETTER PRICING TERMS OR SERVICE, OBTAIN CERTAIN INTELLECTUAL PROPERTY RIGHTS OR IF ANY OF OUR MAJOR CUSTOMERS DEVELOP OR INCREASE IN-HOUSE SLURRY MANUFACTURING CAPABILITY

Competition from current CMP slurry manufacturers, new entrants to the CMP slurry market or a decision by any of our major customers to produce, or increase the production of slurry products in-house could seriously harm our business and results of operations. Competition has increased from other existing providers of CMP slurries and opportunities exist for other companies with sufficient financial or technological resources to emerge as potential competitors by developing their own CMP slurry products. The existence or threat of increased competition and additional in-house production could impact the prices we are able to charge for our slurry products. We may also face competition arising from significant changes in technology, such as the development of polishing pads containing abrasives and emerging technologies such as electrochemical mechanical planarization ("ECMP"). In addition, our competitors could have or obtain intellectual property rights which could restrict our ability to market our existing products and/or to innovate and develop new products.

BECAUSE WE HAVE LIMITED EXPERIENCE IN MANUFACTURING AND SELLING CMP POLISHING PADS, EXPANSION OF OUR BUSINESS INTO THIS AREA MAY NOT BE SUCCESSFUL

An element of our strategy is to leverage our current customer relationships and technological expertise to expand our business into new product areas and applications, including manufacturing and distributing CMP polishing pads. We have had limited experience in developing, manufacturing and marketing these products, which involve technologies and production processes that are relatively new to us. We, our suppliers of the raw materials that we use to develop our polishing pads, or our provider of

17

pads for whom we act as value-added reseller, may not be able to produce products that satisfy our customers' needs. In addition, we, our suppliers or pad provider may be unable to keep pace with technological or other developments in the design and production of polishing pads. Also, our competitors may have or obtain intellectual property rights which could restrict our ability to market our existing products and/or to innovate and develop new products.

WE ARE SUBJECT TO SOME RISKS ASSOCIATED WITH OUR FOREIGN OPERATIONS

We currently have operations and a large customer base outside the United States. Approximately 68% of our revenue was generated by sales to customers outside the United States for our fiscal year ended 2003. For the three months ended December 31, 2003, approximately 73% of our revenue was generated by sales to customers outside the United States. We encounter risks in doing business in certain foreign countries, including but not limited to, adverse changes in economic and political conditions, as well as the difficulty in enforceability of business and customer contracts and agreements, including protection of intellectual property rights. In June 2003 we completed our transition to selling directly to customers in Europe, Singapore and Malaysia who previously had been serviced through a third party distributor. Selling directly may increase our risk of conducting business in foreign countries.

BECAUSE WE RELY HEAVILY ON OUR INTELLECTUAL PROPERTY, OUR FAILURE TO ADEQUATELY OBTAIN OR PROTECT IT COULD SERIOUSLY HARM OUR BUSINESS

Protection of intellectual property is particularly important in our industry because CMP slurry and pad manufacturers develop complex and technical formulas for CMP products which are proprietary in nature and differentiate their products from those of competitors. Our intellectual property is important to our success and ability to compete. We attempt to protect our intellectual property rights through a combination of patent, trademark, copyright and trade secret laws, as well as employee and third-party nondisclosure and assignment agreements. Our failure to obtain or maintain adequate protection of our intellectual property rights for any reason could seriously harm our business.

OUR INABILITY TO ATTRACT AND RETAIN KEY PERSONNEL COULD CAUSE OUR BUSINESS TO SUFFER

If we fail to attract and retain the necessary managerial, technical and customer support personnel, our business and our ability to maintain existing and obtain new customers, develop new products and provide acceptable levels of customer service could suffer. Competition for qualified personnel, particularly those with significant experience in the CMP and IC device industries, is intense. The loss of services of key employees could harm our business and results of operations.

DEMAND FOR OUR PRODUCTS AND OUR BUSINESS MAY BE ADVERSELY AFFECTED BY WORLDWIDE ECONOMIC AND INDUSTRY CONDITIONS

Our business is affected by current economic and industry conditions and it is extremely difficult to predict sales of our products given uncertainties in these factors. For example, our quarterly revenue trends in fiscal years 2001 through 2003 were affected by the global economic slowdown and weakening in demand for electronic systems, coupled with higher than normal chip inventories. While there are currently encouraging indications that the semiconductor industry is recovering from this prolonged downturn, any further declines or lack of improvement in current economic and industry conditions could continue to adversely affect our business.

18

RISKS RELATING TO THE MARKET FOR OUR COMMON STOCK

THE MARKET PRICE MAY FLUCTUATE SIGNIFICANTLY AND RAPIDLY

The market price of our common stock has and could continue to fluctuate significantly as a result of factors such as: economic and stock market conditions generally and specifically as they may impact participants in the semiconductor industry; changes in financial estimates and recommendations by securities analysts following our stock; earnings and other announcements by, and changes in market evaluations of, us or participants in the semiconductor industry; changes in business or regulatory conditions affecting us or participants in the semiconductor industry; announcements or implementation by us, our competitors, or our customers of technological innovations or new products; and trading volume of our common stock.

ANTI-TAKEOVER PROVISIONS UNDER OUR CERTIFICATE OF INCORPORATION AND BYLAWS AND OUR RIGHTS PLAN MAY DISCOURAGE THIRD PARTIES FROM MAKING AN UNSOLICITED BID FOR OUR COMPANY

Our certificate of incorporation, our bylaws, our rights plan and various provisions of the Delaware General Corporation Law may make it more difficult to effect a change in control of our company. For example, our amended certificate of incorporation authorizes our board of directors to issue up to 20 million shares of blank check preferred stock and to attach special rights and preferences to this preferred stock. Also our amended certificate of incorporation provides for the division of our board of directors into three classes as nearly equal in size as possible with staggered three-year terms. In addition, the rights issued to our stockholders under our rights plan may make it more difficult or expensive for another person or entity to acquire control of us without the consent of our board of directors.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

EFFECT OF CURRENCY EXCHANGE RATES AND EXCHANGE RATE RISK MANAGEMENT

We conduct business operations outside of the United States through our foreign operations. Our foreign operations maintain their accounting records in their local currencies. Consequently, period to period comparability of results of operations is affected by fluctuations in exchange rates. The primary currencies to which we have exposure are the Japanese Yen and, to a lesser extent, the British Pound and the Euro. From time to time we enter into forward contracts in an effort to manage foreign currency exchange exposure. However, we may be unable to hedge these exposures completely. Approximately 17% of our revenue is transacted in currencies other than the U.S. dollar. We do not currently enter into forward exchange contracts or other derivative instruments for speculative or trading purposes.

MARKET RISK AND SENSITIVITY ANALYSIS OF FOREIGN EXCHANGE RATE RISK

We have performed a sensitivity analysis assuming a hypothetical 10% adverse movement in foreign exchange rates. As of December 31, 2003, the analysis demonstrated that such market movements would not have a material adverse effect on our consolidated financial position, results of operations or cash flows over a one-year period. Actual gains and losses in the future may differ materially from this analysis based on changes in the timing and amount of foreign currency rate movements and our actual exposures.

ITEM 4. CONTROLS AND PROCEDURES

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, have conducted an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures pursuant to Exchange Act Rule 13a-15(e) and 15d-15(e) as of the end of the period covered by this report. Based on that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures are effective to make

19

known to them in a timely fashion material information related to the Company required to be filed in this report. There have been no significant changes in the Company's internal controls or in other factors that could significantly affect internal controls subsequent to the date of their evaluation.

While we believe the present design of our disclosure controls and procedures is effective to make known to our senior management in a timely fashion all material information concerning our business, we will continue to improve the design and effectiveness of our disclosure controls and procedures to the extent necessary in the future to provide our senior management with timely access to such material information, and to correct any deficiencies that we may discover in the future.

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

We are not currently involved in any material legal proceedings.

ITEM 5. OTHER INFORMATION

Pursuant to Section 10A(i)(2) of the Securities Exchange Act of 1934, as added by Section 202 of the Sarbanes-Oxley Act of 2002, we are responsible for disclosing to investors the non-audit services approved by our Audit Committee to be performed by PricewaterhouseCoopers LLP, our independent auditor. Non-audit services are defined in the law as services other than those provided in connection with an audit or a review of the financial statements of the Company. During the quarter covered by this filing our Audit Committee approved the following non-audit services performed by PricewaterhouseCoopers LLP: (1) tax compliance and consultations related to research and experimentation tax credits; (2) tax compliance and consultations related to our foreign operations; and (3) tax consultations with respect to our Equity Incentive Plan and other compensation plans.

Each such notice shall be effective upon receipt by the Administrative Agent, shall be irrevocable, and shall specify the date, amount and type of borrowing and, in the case of a Eurodollar borrowing, the initial Interest Period therefor. Promptly upon receipt of such notice, the Administrative Agent shall advise each Bank thereof. Not later than 1:00 P.M., Chicago time, on the date of a proposed borrowing, each Bank shall provide the Administrative Agent at the office specified by the Administrative Agent with immediately available funds covering such Bank's Pro Rata Share of such borrowing and, so long as the Administrative Agent has not received written notice that the conditions precedent set forth in Section 11 with respect to such borrowing have not been satisfied, the Administrative Agent shall pay over the funds received by the Administrative Agent to the Company on the requested borrowing date. Each borrowing shall be on a Business Day. Each Base Rate borrowing shall be in an aggregate amount of at least $100,000 and an integral multiple of $10,000, and each Eurodollar borrowing shall be in an aggregate amount of at least $1,000,000 and an integral multiple of at least $500,000.

Unless the Administrative Agent receives notice from a Bank by noon, Chicago time, on the day of a proposed borrowing that such Bank will not make available to the Administrative Agent an amount equal to its Pro Rata Share of such borrowing, the Administrative Agent may assume that such Bank has made such amount available to the Administrative Agent and, in reliance upon such assumption, may make a corresponding amount available to the Company. If and to the extent such Bank has not made such amount available to the Administrative Agent, such Bank and the Company jointly and severally agree to repay such amount to the Administrative Agent forthwith upon demand, together with interest thereon at the interest rate applicable to Loans comprising such borrowing (but without any amount which may

15

become due under Section 8.4 as a result of such repayment) or, in the case of any Bank which repays such amount within three Business Days, the Federal Funds Rate. Nothing set forth in this clause (b) shall relieve any Bank of any obligation it may have to make any Loan hereunder.

2.2.3 Conversion and Continuation Procedures. (a) Subject to Section 2.2.1, the Company may, upon irrevocable written notice to the Administrative Agent in accordance with clause (b) below:

(i) elect, as of any Business Day, to convert any Revolving Loans (or any part thereof in an aggregate amount not less than $1,000,000 or a higher integral multiple of $500,000) into Loans of the other type; or

(ii) elect, as of the last day of the applicable Interest Period, to continue any Eurodollar Loans having Interest Periods expiring on such day (or any part thereof in an aggregate amount not less than $1,000,000 or a higher integral multiple of $500,000) for a new Interest Period;

provided that after giving effect to any prepayment, conversion or continuation, the aggregate principal amount of each Group of Eurodollar Loans shall be at least $1,000,000 and an integral multiple of $500,000.

(b) The Company shall give written or telephonic (followed immediately by written confirmation thereof) notice to the Administrative Agent of each proposed conversion or continuation not later than (i) in the case of conversion into Base Rate Loans, 11:00
A.M., Chicago time, on the proposed date of such conversion and (ii) in the case of conversion into or continuation of Eurodollar Loans, 11:00
A.M., Chicago time, at least three Business Days prior to the proposed date of such conversion or continuation, specifying in each case:

(A) the proposed date of conversion or continuation;

(B) the aggregate amount of Revolving Loans to be converted or continued;

(C) the type of Revolving Loans resulting from the proposed conversion or continuation; and

(D) in the case of conversion into, or continuation of, Eurodollar Loans, the duration of the requested Interest Period therefor.

(c) If upon the expiration of any Interest Period applicable to Eurodollar Loans, the Company has failed to select timely a new Interest Period to be applicable to such Eurodollar Loans, the Company shall be deemed to have elected to convert such Eurodollar Loans into Base Rate Loans effective on the last day of such Interest Period.

(d) The Administrative Agent will promptly notify each Bank of its receipt of a notice of conversion or continuation pursuant to this Section 2.2.3 or, if no timely notice is provided by the Company, of the details of any automatic conversion.

16

(e) Any conversion of a Eurodollar Loan on a day other than the last day of an Interest Period therefor shall be subject to
Section 8.4.

2.2.4 Swing Line Loan Borrowing Procedures.

(a) The Company shall give written notice or telephonic notice (followed immediately by written confirmation thereof) to the Administrative Agent of each proposed borrowing of a Swing Line Loan not later than 11:00 A.M., Chicago time, on the proposed date of such borrowing. Each such notice shall be effective upon receipt by the Administrative Agent, shall be irrevocable, and shall specify the date and amount of borrowing. Promptly upon receipt of such notice, the Administrative Agent shall advise the Swing Line Bank thereof. Not later than 1:00 P.M., Chicago time, on the date of the proposed borrowing, the Swing Line Bank shall provide the Administrative Agent at the office specified by the Administrative Agent with immediately available funds covering such borrowing and, so long as the Administrative Agent has not received written notice that the conditions precedent set forth in Section 11 with respect to such borrowing have not been satisfied, the Administrative Agent shall pay over the funds received by the Administrative Agent to the Company on the requested borrowing date. Each borrowing shall be on a Business Day. Each Swing Line Loan shall be in an aggregate amount of at least $50,000 and an integral multiple of $10,000.

(b) With respect to any Swing Line Loans that have not been voluntarily prepaid by the Company pursuant to Section 6.2.1, the Swing Line Bank may at any time in its sole and absolute discretion, deliver to Administrative Agent (with a copy to the Company), no later than 11:00 a.m., Chicago time, at least one (1) Business Day in advance of the proposed borrowing date, a notice (which shall be deemed to be a notice given by the Company) requesting that each Bank make Revolving Loans that are Base Rate Loans to the Company on such borrowing date in an amount equal to the amount of such Swing Line Loans (the "Refunded Swing Line Loans") outstanding on the date such notice is given which the Swing Line Bank requests the Banks to repay. Anything contained in this Agreement to the contrary notwithstanding, (a) the proceeds of such Revolving Loans made by the Banks other than the Swing Line Bank shall be immediately delivered by the Administrative Agent to the Swing Line Bank (and not to the Company) and applied to repay a corresponding portion of the Refunded Swing Line Loans and (b) on the day such Revolving Loans are made, the Swing Line Bank's Pro Rata Share of the Refunded Swing Line Loans shall be deemed to be paid with the proceeds of a Revolving Loan made by the Swing Line Bank to the Company, and such portion of the Swing Line Loans deemed to be so paid shall no longer be outstanding as Swing Line Loans and shall no longer be due under the Swing Line Note of the Swing Line Bank but shall instead constitute part of the Swing Line Bank's outstanding amounts under the Revolving Loans to the Company and shall be due under the Revolving Loan Note issued by the Company to the Swing Line Bank. The Company hereby authorizes the Administrative Agent and the Swing Line Bank to charge the Company's accounts with the Administrative Agent and the Swing Line Bank (up to the amount available in each such account) in order to immediately pay the Swing Line Bank the amount of the Refunded Swing Line Loans to the extent of the proceeds of such Revolving Loans made by the Banks, including the Revolving Loans deemed to be made by the Swing Line Bank, are not sufficient to repay in full the Refunded Swing Line Loans. If any portion of any such amount paid (or deemed to be paid) to the Swing Line Bank should be recovered by or on behalf of the Company from the Swing Line Bank in bankruptcy, by assignment for the benefit

17

of creditors or otherwise, the loss of the amount so recovered shall be ratably shared among all Lenders in the manner contemplated by Section 7.5.

(c) If for any reason Revolving Loans are not made pursuant to paragraph (b) in an amount sufficient to repay any amounts owed to the Swing Line Bank in respect of any outstanding Swing Line Loans on or before the third Business Day after demand for payment thereof by the Swing Line Bank, each Bank shall be deemed to, and hereby agrees to, have purchased a participation in such outstanding Swing Line Loans, and in an amount equal to its Pro Rata Share of the applicable unpaid amount together with accrued interest thereon. Upon one (1) Business Day's notice from the Swing Line Bank, each Bank shall deliver to the Swing Line Bank an amount equal to its respective participation in the applicable unpaid amount in same day funds. In order to evidence such participation each Bank agrees to enter into a participation agreement at the request of the Swing Line Bank in form and substance reasonably satisfactory to the Swing Line Bank. In the event any Bank fails to make available to the Swing Line Bank the amount of such Bank's participation as provided in this paragraph, the Swing Line Bank shall be entitled to recover such amount on demand from such Bank together with interest thereon for three
(3) Business Days at the rate customarily used by the Swing Line Bank for the correction of errors among banks and thereafter at the Base Rate, as applicable.

(d) Notwithstanding anything contained herein to the contrary, (i) each Bank's obligation to make Revolving Loans for the purpose of repaying any Refunded Swing Line Loans pursuant to paragraph (b) and each Bank's obligation to purchase a participation in any unpaid Swing Line Loans pursuant to paragraph (c) shall be absolute and unconditional and shall not be affected by any circumstance, including without limitation (A) any set-off, counterclaim, recoupment, defense or other right that such Bank may have against the Swing Line Bank, the Company or any other Person for any reason whatsoever; (B) the occurrence or continuation of an Unmatured Event of Default or Event of Default;
(C) any adverse change in the business, operations, properties, assets, condition (financial or otherwise) or prospects of the Company; (D) any breach of this Agreement by any party hereto; or (E) any other circumstance, happening or event whatsoever, whether or not similar to any of the foregoing; provided that such obligations of each Bank are subject to the condition that the Swing Line Bank believed in good faith that all conditions under Section 11.2 to the making of the applicable Refunded Swing Line Loans or other unpaid Swing Line Loans, were satisfied at the time such Refunded Swing Line Loans or unpaid Swing Line Loans were made, or the satisfaction of any such condition not satisfied had been waived by the Required Banks prior to or at the time such Refunded Swing Line Loans or other unpaid Swing Line Loans were made; and (ii) the Swing Line Bank shall not be obligated to make any Swing Line Loans (A) if it has elected not to do so after the occurrence and during the continuation of an Unmatured Event of Default or Event of Default or (B) at a time when a Bank is in default of its obligations hereunder exists unless the Swing Line Bank has entered into arrangements satisfactory to it and the Company to eliminate the Swing Line Bank's risk with respect to such defaulting Bank's participation in such Swing Line Loan, including by cash collateralizing such defaulting Bank's Pro Rata Share of the outstanding Swing Line Loans.

2.3 Letter of Credit Procedures.

2.3.1 L/C Applications. The Company has executed and delivered to the Issuing Bank the Master Letter of Credit Agreement. The Company shall give notice to the Administrative Agent and the Issuing Bank of the proposed issuance of each Letter of Credit on a Business Day which is at least three Business Days (or such lesser number of days as the Administrative Agent and the Issuing Bank shall agree in any particular instance in their sole discretion) prior to the proposed date of issuance of such Letter of Credit. Each such notice shall be accompanied by an L/C Application, duly executed by the Company and in all respects satisfactory to the Administrative Agent and the Issuing Bank, together with such other documentation as the Administrative Agent or the Issuing Bank may request in support thereof, it being understood that each L/C Application shall specify, among other things, the date on which the proposed Letter of Credit is to be issued, the expiration date of such Letter of Credit (which shall not be later than the earlier to occur of (x) one year after the date of issuance thereof and (y) if such Letter of Credit is not Cash Collateralized, twenty-five days prior to the Scheduled Termination Date, provided that any Letter of Credit having an expiration date of one year after the date of issuance may provide for renewal thereof for additional one-year periods, but in no event shall any renewal extend beyond the date which is twenty-five days prior to the Scheduled Termination Date unless such Letter of Credit is Cash Collateralized). So long as the Issuing Bank has not received written notice that the conditions precedent set forth in Section 11 with respect to the issuance of such Letter of Credit have not been satisfied, the Issuing Bank shall issue such Letter of Credit on the requested issuance date. The Issuing Bank shall promptly advise the Administrative Agent of the issuance of each Letter of Credit and of any amendment thereto, extension thereof or event or circumstance changing the amount available for drawing thereunder. In the event of any inconsistency between the terms of the Master Letter of Credit Agreement, any L/C Application and the terms of this Agreement, the terms of this Agreement shall control.

2.3.2 Participations in Letters of Credit. Concurrently with the issuance of each Letter of Credit, the Issuing Bank shall be deemed to have sold and transferred to each other Bank, and each other Bank shall be deemed irrevocably and unconditionally to have purchased and received from the Issuing Bank, without recourse or warranty, an undivided interest and participation, to the extent of such other Bank's Pro Rata Share, in such Letter of Credit and the Company's reimbursement obligations with respect thereto. For the purposes of this Agreement, the unparticipated portion of each Letter of Credit shall be deemed to be the Issuing Bank's "participation" therein. The Issuing Bank hereby agrees, upon request of the Administrative Agent or any Bank, to deliver to the Administrative Agent or such Bank a list of all outstanding Letters of Credit issued by the Issuing Bank, together with such information related thereto as the Administrative Agent or such Bank may reasonably request.

2.3.3 Reimbursement Obligations. The Company hereby unconditionally and irrevocably agrees to reimburse the Issuing Bank for each payment or disbursement made by the Issuing Bank under any Letter of Credit honoring any demand for payment made by the beneficiary thereunder, in each case on the date that such payment or disbursement is made. Any amount not reimbursed on the date of such payment or disbursement shall bear interest from the date of such payment or disbursement to the date that the Issuing Bank is reimbursed by the Company therefor, payable on demand, at a rate per annum equal to the Base Rate from time to

19

time in effect plus the Base Rate Margin from time to time in effect plus, beginning on the third Business Day after receipt of notice from the Issuing Bank of such payment or disbursement, 2%. The Issuing Bank shall notify the Company and the Administrative Agent whenever any demand for payment is made under any Letter of Credit by the beneficiary thereunder; provided that the failure of the Issuing Bank to so notify the Company shall not affect the rights of the Issuing Bank or the Banks in any manner whatsoever.

2.3.4 Limitation on Obligations of Issuing Bank. In determining whether to pay under any Letter of Credit, the Issuing Bank shall not have any obligation to the Company or any Bank other than to confirm that any documents required to be delivered under such Letter of Credit appear to have been delivered and substantially comply on their face with the requirements of such Letter of Credit. Any action taken or omitted to be taken by the Issuing Bank under or in connection with any Letter of Credit, if taken or omitted in the absence of gross negligence and willful misconduct, shall not impose upon the Issuing Bank any liability to the Company or any Bank and shall not reduce or impair the Company's reimbursement obligations set forth in Section 2.3.3 or the obligations of the Banks pursuant to Section 2.3.5.

2.3.5 Funding by Banks to Issuing Bank. If the Issuing Bank makes any payment or disbursement under any Letter of Credit and the Company has not reimbursed the Issuing Bank in full for such payment or disbursement by 11:00 A.M., Chicago time, on the date of such payment or disbursement, or if any reimbursement received by the Issuing Bank from the Company is or must be returned or rescinded upon or during any bankruptcy or reorganization of the Company or otherwise, each other Bank shall be obligated to pay to the Administrative Agent for the account of the Issuing Bank, in full or partial payment of the purchase price of its participation in such Letter of Credit, its Pro Rata Share of such payment or disbursement (but no such payment shall diminish the obligations of the Company under Section 2.3.3), and, upon notice from the Issuing Bank, the Administrative Agent shall promptly notify each other Bank thereof. Each other Bank irrevocably and unconditionally agrees to so pay to the Administrative Agent in immediately available funds for the Issuing Bank's account the amount of such other Bank's Pro Rata Share of such payment or disbursement. If and to the extent any Bank shall not have made such amount available to the Administrative Agent by 2:00 P.M., Chicago time, on the Business Day on which such Bank receives notice from the Administrative Agent of such payment or disbursement (it being understood that any such notice received after noon, Chicago time, on any Business Day shall be deemed to have been received on the next following Business Day), such Bank agrees to pay interest on such amount to the Administrative Agent for the Issuing Bank's account forthwith on demand, for each day from the date such amount was to have been delivered to the Administrative Agent to the date such amount is paid, at a rate per annum equal to (a) for the first three days after demand, the Federal Funds Rate from time to time in effect and (b) thereafter, the Base Rate from time to time in effect. Any Bank's failure to make available to the Administrative Agent its Pro Rata Share of any such payment or disbursement shall not relieve any other Bank of its obligation hereunder to make available to the Administrative Agent such other Bank's Pro Rata Share of such payment, but no Bank shall be responsible for the failure of any other Bank to make available to the Administrative Agent such other Bank's Pro Rata Share of any such payment or disbursement.

2.4 Commitments Several. The failure of any Bank to make a requested Loan on any date shall not relieve any other Bank of its obligation (if any) to make a Loan on such date, but

20

no Bank shall be responsible for the failure of any other Bank to make any Loan to be made by such other Bank.

2.5 Certain Conditions. Notwithstanding any other provision of this Agreement, no Bank shall have an obligation to make any Loan, or to permit the continuation of or any conversion into any Eurodollar Loan, and the Issuing Bank shall not have any obligation to issue any Letter of Credit, if an Event of Default or Unmatured Event of Default exists.

2.6 Renewal Options.

(a) Subject to the terms and conditions of this Section 2.6, provided no Unmatured Event of Default or Event of Default then exists and with the prior written consent of the Banks (which consent shall not be unreasonably withheld or delayed and shall not include any requirement of payment of any fee solely on account of the exercise of such Renewal Option if no other term or provision of this Agreement or the other Loan Documents is being amended) (i) prior to the second anniversary of the Closing Date the Company may elect to extend the Scheduled Termination Date from November 24, 2006 to November 24, 2007 (the "First Renewal Option") and (ii) if the Company has properly exercised the First Renewal Option and the Banks have consented to the extension of the Scheduled Termination Date from November 24, 2006 to November 24, 2007, prior to the third anniversary of the Closing Date the Company may elect to extend further the Scheduled Termination Date from November 24, 2007 to November 24, 2008 (the "Second Renewal Option" and, together with the First Renewal Option, the "Renewal Options"). The Company may exercise a Renewal Option solely by delivering to the Administrative Agent not more than 120 days nor less than 60 days prior to the second anniversary of the Closing Date (in the case of the First Renewal Option) or the third anniversary of the Closing Date (in the case of the Second Renewal Option) written notice of its election to exercise such Renewal Option. Each such notice shall be effective upon receipt by the Administrative Agent and shall be irrevocable. Promptly upon receipt of such notice, the Administrative Agent shall advise the Banks thereof. Each Bank shall deliver to the Administrative Agent either its written consent or written refusal to the applicable extension not later than the date (the "Determination Date") which is 30 days prior to the second anniversary of the Closing Date (in the case of the exercise by the Company of the First Renewal Option) or the third anniversary of the Closing Date (in the case of the exercise by the Company of the Second Renewal Option. Any Bank which fails to deliver such written consent to the Administrative Agent not later than the applicable Determination Date shall be deemed for all purposes irrevocably to have consented to the applicable extension. Under no circumstances shall any Bank be liable to or under any obligation to the Company for the failure of any other Bank to consent to the applicable extension, and in no event shall the Scheduled Termination Date be extended unless all Banks consent to such extension.

(b) If any Bank other than LaSalle delivers to the Administrative Agent its written refusal to any applicable extension as described in the preceding paragraph (a), then, if no Event of Default has occurred and is continuing, the Company may designate a Replacement Bank to purchase the Loans of such Bank and such Bank's rights hereunder, without recourse to or warranty by, or expense to, such Bank, for a purchase price equal to the outstanding principal amount of the Loans payable to such Bank plus any accrued but unpaid interest on such Loans and all accrued but unpaid fees owed to such Bank and any other amounts payable to such Bank

21

under this Agreement (excluding, however, in the event the aggregate Pro Rata Shares of the Banks being replaced are less than 25%, all amounts, if any, which otherwise would be payable to such Bank pursuant to Section 8.4 hereof), and to assume all the obligations of such Bank hereunder, and, upon such purchase and assumption (pursuant to an Assignment Agreement), such Bank shall no longer be a party hereto or have any rights hereunder (other than rights with respect to indemnities and similar rights applicable to such Bank prior to the date of such purchase and assumption) and shall be relieved from all obligations to the Company hereunder, and the Replacement Bank shall succeed to the rights and obligations of such Bank hereunder.

2.7 New Revolving Loans.

(a) Subject to the terms and conditions of this Section 2.7, at any time and from time to time but prior to the Termination Date, by written notice to the Administrative Agent, the Company may elect to request an increase in the aggregate amount of the existing Revolving Loan Commitments (any such increase, the "New Revolving Loan Commitments") by an amount not in excess of $30,000,000 in the aggregate and not less than $5,000,000 individually (or such lesser amount which shall be approved by the Administrative Agent or such lesser amount that shall constitute the difference between $30,000,000 and all such New Revolving Loan Commitments obtained prior to such date) and integral multiples of $1,000,000 in excess of that amount. Each such notice shall specify (i) the date (each, an "Increased Revolving Loan Amount Date") on which the Company proposes that the New Revolving Loan Commitments shall be effective, which shall be a date not less than ten (10) Business Days after the date on which such notice is delivered to the Administrative Agent and (ii) the identity of each New Bank to whom the Company proposes any portion of such New Revolving Loan Commitments, as applicable, be allocated and the amounts of such allocations; provided that any Bank approached to provide all or a portion of the New Revolving Loan Commitments may elect or decline, in its sole discretion, to provide a New Revolving Loan Commitment and further provided that the Company first shall offer the New Revolving Loan Commitments to the existing Banks and the Company shall accept any New Revolving Loan Commitment which any such Bank elects to provide. In the event of any oversubscription for New Revolving Loan Commitments the Administrative Agent shall determine the final allocation amounts. Such New Revolving Loan Commitments shall become effective as of such Increased Revolving Loan Amount Date; provided that (1) no Default or Event of Default shall exist on such Increased Revolving Loan Amount Date before or after giving effect to such New Revolving Loan Commitments; (2) the New Revolving Loan Commitments shall be effected pursuant to one or more Joinder Agreements executed and delivered by the Company, the New Banks and the Administrative Agent and shall be subject to the requirements set forth in Section 7.6; (3) the Company shall, if applicable, make any payments required pursuant to Sections 8.4 and 5.3 in connection with the New Revolving Loan Commitments; and (4) the Company shall deliver or cause to be delivered any legal opinions or other documents reasonably requested by the Administrative Agent in connection with any such transaction. No arrangement fee shall be charged by the Administrative Agent for its own account in connection with the New Revolving Loan Commitments.

(b) Effective upon any Increased Revolving Loan Amount Date, (i) each New Revolving Loan Commitment shall be deemed for all purposes a Revolving Loan Commitment and each Loan made thereunder (a "New Revolving Loan") shall be deemed, for all purposes, a

22

Revolving Loan, and (ii) each New Bank shall become a Bank with respect to the New Revolving Loan Commitment and all matters relating thereto. In addition, any Revolving Loans made on or after any Increased Revolving Loan Amount Date shall be made pro rata based on the Revolving Loan Commitments in effect on and after such Increased Revolving Loan Amount Date (which shall reflect the New Revolving Loan Commitments), and continuations of Eurodollar Rate Loans outstanding on such Increased Revolving Loan Amount Date shall be effected by repayment of such Eurodollar Loans on the last day of the Interest Period applicable thereto and the making of new Eurodollar Loans pro rata based on the Revolving Loan Commitments in effect on and after such Increased Revolving Loan Amount Date (which shall reflect the New Revolving Loan Commitments). In the event that on any Increased Revolving Loan Amount Date there are a sufficient amount of unpaid Base Rate Loans, then the Company shall make prepayments thereof and new borrowings of Base Rate Loans so that, after giving effect thereto, the Base Rate Loans outstanding on such Increased Revolving Loan Amount Date are held pro rata based on the Revolving Loan Commitments in effect on such Increased Revolving Loan Amount Date. In the event that on any such Increased Revolving Loan Amount Date there are any Eurodollar Loans outstanding, such Eurodollar Loans shall remain outstanding with respect to the holders thereof until the expiration of their respective Interest Periods (unless the Company elects to prepay any thereof in accordance with the applicable provisions of this Agreement), and interest on and repayments of such Eurodollar Loans will be paid thereon to the respective Banks holding such Eurodollar Loans pro rata based on the respective principal amounts thereof outstanding.

(c) The Administrative Agent shall notify the Banks promptly upon receipt of the Company's notice of each Increased Revolving Loan Amount Date and in respect thereof (i) the New Revolving Loan Commitments and the New Banks, and
(ii) in the case of each notice to any Bank of Revolving Loans, the respective interests in such Bank's Revolving Loans, in each case subject to the assignments contemplated by this Section. The terms, provisions and interest rate of the New Revolving Loans shall be identical to the Revolving Loans.

SECTION 3 NOTES EVIDENCING LOANS

3.1 Notes. The Revolving Loans of each Bank shall be evidenced by a promissory note (each, a "Revolving Note") substantially in the form set forth in Exhibit A-1, with appropriate insertions, payable to the order of such Bank in a face principal amount equal to such Bank's Pro Rata Share of the Revolving Loan Commitment. Each Revolving Loan of such Bank shall be paid in full on the Termination Date. The Swing Line Loans of the Swing Line Bank shall be evidenced by a promissory note (the "Swing Line Note") substantially in the form set forth in Exhibit A-2, payable to the order of the Swing Line Bank in a face principal amount equal to $5,000,000.00. The Swing Line Loans shall be paid in full on the Termination Date.

3.2 Recordkeeping. Each Bank shall record in its records, or at its option on the schedule attached to its Notes, the date and amount of each Loan made by such Bank, each repayment or conversion thereof and, in the case of each Eurodollar Loan, the dates on which each Interest Period for such Loan shall begin and end. The aggregate unpaid principal amount so recorded shall be rebuttable presumptive evidence of the principal amount owing and unpaid on such Note. The failure to so record any such amount or any error in so recording any such

23

amount shall not, however, limit or otherwise affect the obligations of the Company hereunder or under any Note to repay the principal amount of the Loans evidenced by such Notes together with all interest accruing thereon.

SECTION 4 INTEREST

4.1 Interest Rates. The Company promises to pay interest on the unpaid principal amount of each Loan for the period commencing on the date of such Loan until such Loan is paid in full as follows:

(a) at all times while such Loan is a Base Rate Loan, at a rate per annum equal to the sum of the Base Rate from time to time in effect plus the Base Rate Margin from time to time in effect; and

(b) at all times while such Loan is a Eurodollar Loan, at a rate per annum equal to the sum of the Eurodollar Rate applicable to each Interest Period for such Loan plus the Eurodollar Margin from time to time in effect;

provided that at any time an Event of Default exists, if requested by the Required Banks, the interest rate applicable to each Loan shall be increased by 2% per annum.

4.2 Interest Payment Dates. Accrued interest on each Base Rate Loan shall be payable in arrears on the last day of each calendar quarter and at maturity. Accrued interest on each Eurodollar Loan shall be payable on the last day of each Interest Period relating to such Loan (and, in the case of a Eurodollar Loan with a six-month Interest Period, on the three-month anniversary of the first day of such Interest Period) and at maturity. After maturity, accrued interest on all Loans shall be payable on demand. All accrued interest not paid when due shall, to the extent permitted by law, bear interest from the date due until paid at the Base Rate from time to time in effect plus the Base Rate Margin from time to time in effect plus 2% per annum.

4.3 Setting and Notice of Eurodollar Rates. The applicable Eurodollar Rate for each Interest Period shall be determined by the Administrative Agent, and notice thereof shall be given by the Administrative Agent promptly to the Company and each Bank. Each determination of the applicable Eurodollar Rate by the Administrative Agent shall be conclusive and binding upon the parties hereto, in the absence of demonstrable error. The Administrative Agent shall, upon written request of the Company or any Bank, deliver to the Company or such Bank a statement showing the computations used by the Administrative Agent in determining any applicable Eurodollar Rate hereunder.

4.4 Computation of Interest. Interest shall be computed for the actual number of days elapsed on the basis of a year of 360 days. The applicable interest rate for each Base Rate Loan shall change simultaneously with each change in the Base Rate.

SECTION 5 FEES

5.1 Non-Use Fee. The Company agrees to pay to the Administrative Agent for the account of each Bank a non-use fee, for the period from the Closing Date to the Termination Date, at the Non-Use Fee Rate in effect from time to time of such Bank's Pro Rata Share (as adjusted from time to time) of the unused amount of the Revolving Loan Commitments. For purposes of calculating usage under this Section, the Revolving Loan Commitments shall be deemed used to the extent of the aggregate principal amount of all outstanding Revolving Loans plus the Stated Amount of all Letters of Credit. The aggregate principal amount of all outstanding Swing Line Loans shall not be deemed usage under this Section. Such non-use fee shall be payable in arrears on the last day of each calendar quarter and on the Termination Date for any period then ending for which such non-use fee shall not have previously been paid. The non-use fee shall be computed for the actual number of days elapsed on the basis of a year of 360 days.

5.2 Letter of Credit Fees. (a) The Company agrees to pay to the Administrative Agent for the account of each Bank a letter of credit fee for each Letter of Credit equal to the LC Fee Rate in effect from time to time of such Bank's Pro Rata Share (as adjusted from time to time) of the undrawn amount of such Letter of Credit (computed for the actual number of days elapsed on the basis of a year of 360 days); provided that, if requested by the Required Banks, the rate applicable to each Letter of Credit shall be increased by 2% per annum at any time that an Event of Default exists. Such letter of credit fee shall be payable in arrears on the last day of each calendar quarter and on the Termination Date for the period from the date of the issuance of each Letter of Credit (or the last day on which the letter of credit fee was paid with respect thereto) to the date such payment is due or, if earlier, the date on which such Letter of Credit expired or was terminated.

(b) In addition, with respect to each Letter of Credit, the Company agrees to pay to the Issuing Bank, for its own account, (i) such fees and expenses as the Issuing Bank customarily requires in connection with the issuance, negotiation, processing and/or administration of letters of credit in similar situations and (ii) a letter of credit fronting fee of 0.125%.

5.3 Upfront Fees. The Company agrees to pay to the Administrative Agent for the account of each Bank on the Closing Date an upfront fee as set forth in the Fee Letter Agreement (and the Administrative Agent agrees to promptly forward to each Bank a portion of such upfront fee in the amount previously agreed to between the Administrative Agent and such Bank). The Company further agrees to pay to the Administrative Agent for the account of each Bank which provides a New Revolving Loan Commitment on the Increased Revolving Loan Amount Date an upfront fee on the New Revolving Loan Commitment of such Bank in the same amount as the upfront fee paid on the Closing Date as set forth in the Fee Letter Agreement (and the Administrative Agent agrees to promptly forward to each such Bank a portion of such upfront fee in the amount agreed to between the Administrative Agent and such Bank).

5.4 Administrative Agent's Fees. The Company agrees to pay to the Administrative Agent, as and when due, the fees set forth in the Fee Letter Agreement or as are otherwise mutually agreed to from time to time by the Company and the Administrative Agent.

5.5 Other Due Fees and Other Amounts. All fees and other amounts due under this Agreement and the other Loan Documents which are not paid when due shall, to the extent permitted by law, bear interest from the date due until paid at the Base Rate from time to time in effect plus the Base Rate Margin from time to time in effect plus 2% per annum.

SECTION 6 REDUCTION OR TERMINATION OF THE
COMMITMENT AMOUNTS; PREPAYMENTS

6.1 Reduction or Termination of the Revolving Loan Commitments.

6.1.1 Voluntary Reduction or Termination of the Revolving Loan Commitments. The Company may from time to time on at least five Business Days' prior written notice received by the Administrative Agent (which shall promptly advise each Bank thereof) permanently reduce the Revolving Loan Commitments to an amount not less than the Revolving Outstandings. Any such reduction shall be in an amount not less than $2,000,000 or a higher integral multiple of $2,000,000. Concurrently with any reduction of the Revolving Loan Commitments to zero, the Company shall pay all interest on the Revolving Loans, all non-use fees and all letter of credit fees and shall Cash Collateralize in full all obligations arising with respect to the Letters of Credit.

6.1.2 Mandatory Reductions of the Revolving Loan Commitments. If a Mandatory Prepayment Event occurs prior to the Termination Date, then, on the date of such Mandatory Prepayment Event, the Revolving Loan Commitments shall be permanently reduced by an amount (if any) equal to the Designated Proceeds of such Mandatory Prepayment Event.

6.1.3 Intentionally Omitted.

6.1.4 All Reductions of the Revolving Loan Commitments. All reductions of the Revolving Loan Commitments shall reduce the Revolving Loan Commitments pro rata among the Banks according to their respective Pro Rata Shares.

6.2 Prepayments.

6.2.1 Voluntary Prepayments. The Company may from time to time prepay the Loans in whole or in part; provided that the Company shall give the Administrative Agent (which shall promptly advise each Bank) notice thereof not later than 11:00 A.M., Chicago time, on the day of such prepayment (which shall be a Business Day), specifying the Loans to be prepaid and the date and amount of prepayment. Any such partial prepayment shall be in an amount equal to $100,000 or a higher integral multiple of $10,000.

6.2.2 Mandatory Prepayments.

(a) The Company shall make a prepayment of the Loans upon the occurrence of any of the following (each a "Mandatory Prepayment Event") at the following times and in the following amounts (such applicable amounts being referred to as "Designated Proceeds"):

26

(i) Concurrently with the receipt by the Company or any Subsidiary of Net Cash Proceeds from Asset Sales in an aggregate amount in excess of $2,000,000 in any Fiscal Year, in an amount equal to 100% of such excess; and

(ii) Concurrently with the receipt by the Company or any Subsidiary of any Net Cash Proceeds from any issuance of any Mortgage Debt, in an amount equal to 100% of such Net Cash Proceeds.

(b) If on any day on which the Revolving Loan Commitments are reduced pursuant to Section 6.1.2 the Revolving Outstandings exceed the Revolving Loan Commitments, the Company shall immediately prepay Revolving Loans or Cash Collateralize the outstanding Letters of Credit, or do a combination of the foregoing, in an amount sufficient to eliminate such excess.

6.3 All Prepayments. Each voluntary partial prepayment shall be in a principal amount of $100,000 or a higher integral multiple of $10,000. Any partial prepayment of a Group of Eurodollar Loans shall be subject to the proviso to Section 2.2.3(a). Any prepayment of a Eurodollar Loan on a day other than the last day of an Interest Period therefor shall include interest on the principal amount being repaid and shall be subject to Section 8.4.

SECTION 7 MAKING AND PRORATION OF PAYMENTS; SETOFF; TAXES

7.1 Making of Payments. All payments of principal of or interest on the Notes, and of all fees, shall be made by the Company to the Administrative Agent in immediately available funds at the office specified by the Administrative Agent not later than noon, Chicago time, on the date due; and funds received after that hour shall be deemed to have been received by the Administrative Agent on the following Business Day. The Administrative Agent shall promptly remit to each Bank its share of all such payments received in collected funds by the Administrative Agent for the account of such Bank, net of any amounts owed by such Bank to Administrative Agent under Section 2.2.2(b). All payments under Section 8.1 shall be made by the Company directly to the Bank entitled thereto. Unless the Administrative Agent receives notice from the Company prior to the due date for any payment hereunder that the Company does not intend to make such payment, the Administrative Agent may assume that the Company has made such payment and, in reliance upon such assumption, make available to each Bank its share of such payment, net of any amounts owed by such Bank to Administrative Agent under Section 2.2.2(b). If and to the extent that the Company has not made any such payment to the Administrative Agent, each Bank which received a share of such payment shall repay such share (or the relevant portion thereof) to the Administrative Agent forthwith upon demand, together with interest thereon at the Base Rate (or, in the case of any Bank which repays such amount within three Business Days, the Federal Funds Rate). Nothing set forth in this Section 7.1 shall relieve the Company of any obligation it may have to make any payment hereunder.

7.2 Application of Certain Payments. Each payment of principal shall be applied to the Loans as the Company shall direct by notice to be received by the Administrative Agent on or before the date of such payment or, in the absence of such notice, as the Administrative Agent shall determine in its discretion. Concurrently with each remittance to any Bank of its share of

27

any such payment, the Administrative Agent shall advise such Bank as to the application of such payment. Notwithstanding the foregoing, after an Event of Default has occurred and is continuing, the Administrative Agent may apply any payments as the Administrative Agent shall determine in its sole discretion.

7.3 Due Date Extension. If any payment of principal or interest with respect to any of the Loans, or of any fees, falls due on a day which is not a Business Day, then such due date shall be extended to the immediately following Business Day (unless, in the case of a Eurodollar Loan, such immediately following Business Day is the first Business Day of a calendar month, in which case such due date shall be the immediately preceding Business Day) and, in the case of principal, additional interest shall accrue and be payable for the period of any such extension.

7.4 Waiver of Setoff Rights. The Administrative Agent, the Issuing Bank, the Syndication Agent, each Bank and the Company each hereby affirmatively waive all rights of set-off provided by applicable law with regard to any claim arising under or with respect to this Credit Agreement and their respective obligations hereunder. Without limiting the generality of the foregoing, the Administrative Agent and each Bank acknowledge and agree that none of them will apply to the payment of any obligations of the Company hereunder, whether or not due and whether or not any Event of Default exists, any balances, credits, deposits, accounts or moneys of the Company now or hereafter maintained with the Administrative Agent or such Bank or, in the absence of any order, decree, garnishment, injunction or other decision in a legal process or proceeding to the contrary, prohibit or freeze access to such balances, credits, deposits, accounts or moneys.

7.5 Proration of Payments. If any Bank shall obtain any payment or other recovery (whether voluntary, involuntary, by application of offset or otherwise, but excluding any payment pursuant to Section 8.7 or 14.9 and payments of interest on any Affected Loan) on account of principal of or interest on any Loan (or on account of its participation in any Letter of Credit) in excess of its pro rata share of payments and other recoveries obtained by all Banks on account of principal of and interest on the Loans (or such participation) then held by them, such Bank shall purchase from the other Banks such participations in the Loans (or sub-participations in Letters of Credit) held by them as shall be necessary to cause such purchasing Bank to share the excess payment or other recovery ratably with each of them; provided that if all or any portion of the excess payment or other recovery is thereafter recovered from such purchasing Bank, the purchase shall be rescinded and the purchase price restored to the extent of such recovery.

7.6 Taxes. All payments of principal of, and interest on, the Loans and all other amounts payable hereunder shall be made free and clear of and without deduction for any present or future income, excise, stamp or franchise taxes and other taxes, fees, duties, withholdings or other charges of any nature whatsoever imposed by any taxing authority, excluding franchise taxes and taxes imposed on or measured by any Bank's net income or receipts (all non-excluded items being called "Taxes"). If any withholding or deduction from any payment to be made by the Company hereunder is required in respect of any Taxes pursuant to any applicable law, rule or regulation, then the Company will:

28

(a) pay directly to the relevant authority the full amount required to be so withheld or deducted;

(b) promptly forward to the Administrative Agent an official receipt or other documentation satisfactory to the Administrative Agent evidencing such payment to such authority; and

(c) pay to the Administrative Agent for the account of the Banks such additional amount or amounts as is necessary to ensure that the net amount actually received by each Bank will equal the full amount such Bank would have received had no such withholding or deduction been required.

Moreover, if any Taxes are directly asserted against the Administrative Agent or any Bank with respect to any payment received by the Administrative Agent or such Bank hereunder, the Administrative Agent or such Bank may pay such Taxes and the Company will promptly pay such additional amounts (including any penalty, interest or expense arising due to any act or omission of the Company) as is necessary in order that the net amount received by such Person after the payment of such Taxes (including any Taxes on such additional amount) shall equal the amount such Person would have received had such Taxes not been asserted.

If the Company fails to pay any Taxes when due to the appropriate taxing authority or fails to remit to the Administrative Agent, for the account of the respective Banks, the required receipts or other required documentary evidence, the Company shall indemnify the Banks for any incremental Taxes, interest or penalties that may become payable by any Bank as a result of any such failure. For purposes of this Section 7.6, a distribution hereunder by the Administrative Agent or any Bank to or for the account of any Bank shall be deemed a payment by the Company.

Each Bank that (a) is organized under the laws of a jurisdiction other than the United States of America and (b)(i) is a party hereto on the Closing Date or (ii) becomes an assignee of an interest under this Agreement under
Section 14.9.1 after the Closing Date (unless such Bank was already a Bank hereunder immediately prior to such assignment) shall execute and deliver to the Company and the Administrative Agent one or more (as the Company or the Administrative Agent may reasonably request) United States Internal Revenue Service Form W-8BEN or W-8ECI (or any successor forms) and such other forms or documents, appropriately completed and duly executed by such Bank, as may be applicable to establish that such Bank is exempt from withholding or deduction of Taxes. The Company shall not be required to pay additional amounts to any Bank pursuant to this Section 7.6 to the extent that the obligation to pay such additional amounts would not have arisen but for the failure of such Bank to comply with this paragraph.

SECTION 8 INCREASED COSTS; SPECIAL PROVISIONS FOR EURODOLLAR LOANS

8.1 Increased Costs. (a) If, after the Closing Date, the adoption of, or any change in, any applicable law, rule or regulation, or any change in the interpretation or administration of any applicable law, rule or regulation by any governmental authority, central bank or comparable

29

agency charged with the interpretation or administration thereof, or compliance by any Bank (or any Eurodollar Office of such Bank) with any request or directive (whether or not having the force of law) of any such authority, central bank or comparable agency:

(i) shall subject any Bank (or any Eurodollar Office of such Bank) to any tax, duty or other charge with respect to its Eurodollar Loans, its Notes or its obligation to make Eurodollar Loans, or shall change the basis of taxation of payments to any Bank of the principal of or interest on its Eurodollar Loans or any other amounts due under this Agreement in respect of its Eurodollar Loans or its obligation to make Eurodollar Loans (except for changes in the rate of tax on the overall net income of such Bank or its Eurodollar Office imposed by the jurisdiction in which such Bank's principal executive office or Eurodollar Office is located);

(ii) shall impose, modify or deem applicable any reserve (including any reserve imposed by the FRB, but excluding any reserve included in the determination of interest rates pursuant to Section 4), special deposit or similar requirement against assets of, deposits with or for the account of, or credit extended by any Bank (or any Eurodollar Office of such Bank); or

(iii) shall impose on any Bank (or its Eurodollar Office) any other condition affecting its Eurodollar Loans, its Notes or its obligation to make Eurodollar Loans;

and the result of any of the foregoing is to increase the cost to (or to impose a cost on) such Bank (or any Eurodollar Office of such Bank) of making or maintaining any Eurodollar Loan, or to reduce the amount of any sum received or receivable by such Bank (or its Eurodollar Office) under this Agreement or under its Notes with respect thereto, then upon demand by such Bank (which demand shall be accompanied by a statement setting forth the basis for such demand and a calculation of the amount thereof in reasonable detail, a copy of which shall be furnished to the Administrative Agent), the Company shall pay directly to such Bank such additional amount as will compensate such Bank for such increased cost or such reduction.

(b) If any Bank shall determine that the adoption or phase- in of, any applicable law, rule or regulation regarding capital adequacy or any change therein, or any change in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Bank or any Person controlling such Bank with any request or directive regarding capital adequacy (whether or not having the force of law) of any such authority, central bank or comparable agency, has or would have the effect of reducing the rate of return on such Bank's or such controlling Person's capital as a consequence of such Bank's obligations hereunder or under any Letter of Credit to a level below that which such Bank or such controlling Person could have achieved but for such adoption, phase-in, change or compliance (taking into consideration such Bank's or such controlling Person's policies with respect to capital adequacy) by an amount deemed by such Bank or such controlling Person to be material, then from time to time, upon demand by such Bank (which demand shall be accompanied by a statement setting forth the basis for such demand and a calculation of the amount thereof in reasonable detail, a copy of which shall be furnished to the Administrative Agent), the Company shall pay to such

30

Bank such additional amount as will compensate such Bank or such controlling Person for such reduction.

8.2 Basis for Determining Interest Rate Inadequate or Unfair. If with respect to any Interest Period:

(a) deposits in U.S. dollars (in the applicable amounts) are not being offered to the Administrative Agent in the interbank eurodollar market for such Interest Period, or the Administrative Agent otherwise determines (which determination shall be binding and conclusive on the Company) that by reason of circumstances affecting the interbank eurodollar market adequate and reasonable means do not exist for ascertaining the applicable Eurodollar Rate; or

(b) Banks having aggregate Pro Rata Shares of 25% or more shall reasonably determine and shall so advise the Administrative Agent that due to economic or other conditions affecting generally the eurodollar market which are not due to any act, omission, event or determination within the direct control of such Banks, the Eurodollar Rate as determined by the Administrative Agent will not adequately and fairly reflect the cost to such Banks of maintaining or funding Eurodollar Loans for such Interest Period or that the making or funding of Eurodollar Loans has become impracticable as a result of an event occurring after the date of this Agreement;

then the Administrative Agent shall promptly notify the other parties thereof and, so long as such circumstances shall continue, (i) no Bank shall be under any obligation to make or convert into Eurodollar Loans and (ii) on the last day of the current Interest Period for each Eurodollar Loan, such Loan shall, unless then repaid in full, automatically convert to a Base Rate Loan.

8.3 Changes in Law Rendering Eurodollar Loans Unlawful. If any change in (including the adoption of any new) applicable law or regulation, or any change in the interpretation of any applicable law or regulation by any governmental or other regulatory body charged with the administration thereof, should make it (or in the good faith judgment of any Bank cause a substantial question as to whether it is) unlawful for any Bank to make, maintain or fund Eurodollar Loans, then such Bank shall promptly notify each of the other parties hereto and, so long as such circumstances shall continue, (a) such Bank shall have no obligation to make or convert into Eurodollar Loans (but shall make Base Rate Loans concurrently with the making of or conversion into Eurodollar Loans by the Banks which are not so affected, in each case in an amount equal to the amount of Eurodollar Loans which would be made or converted into by such Bank at such time in the absence of such circumstances) and (b) on the last day of the current Interest Period for each Eurodollar Loan of such Bank (or, in any event, on such earlier date as may be required by the relevant law, regulation or interpretation), such Eurodollar Loan shall, unless then repaid in full, automatically convert to a Base Rate Loan. Each Base Rate Loan made by a Bank which, but for the circumstances described in the foregoing sentence, would be a Eurodollar Loan (an "Affected Loan") shall remain outstanding for the same period as the Group of Eurodollar Loans of which such Affected Loan would be a part absent such circumstances.

31

8.4 Funding Losses. The Company hereby agrees that upon written demand by any Bank (which demand shall be accompanied by a statement setting forth the basis for the amount being claimed, a copy of which shall be furnished to the Administrative Agent), the Company will indemnify such Bank against any net loss or expense that such Bank may sustain or incur (including any net loss or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by such Bank to fund or maintain any Eurodollar Loan), as reasonably determined by such Bank, as a result of (a) any payment, prepayment or conversion of any Eurodollar Loan of such Bank on a date other than the last day of an Interest Period for such Loan (including any conversion pursuant to
Section 8.3) or (b) any failure of the Company to borrow, convert or continue any Loan on a date specified therefor in a notice of borrowing, conversion or continuation pursuant to this Agreement. For this purpose, all notices to the Administrative Agent pursuant to this Agreement shall be deemed to be irrevocable.

8.5 Right of Banks to Fund through Other Offices. Each Bank may, if it so elects, fulfill its commitment as to any Eurodollar Loan by causing a foreign branch or Affiliate of such Bank to make such Loan; provided that in such event for the purposes of this Agreement such Loan shall be deemed to have been made by such Bank and the obligation of the Company to repay such Loan shall nevertheless be to such Bank and shall be deemed held by it, to the extent of such Loan, for the account of such branch or Affiliate.

8.6 Discretion of Banks as to Manner of Funding. Notwithstanding any provision of this Agreement to the contrary, each Bank shall be entitled to fund and maintain its funding of all or any part of its Loans in any manner it sees fit, it being understood, however, that for the purposes of this Agreement all determinations hereunder shall be made as if such Bank had actually funded and maintained each Eurodollar Loan during each Interest Period for such Loan through the purchase of deposits having a maturity corresponding to such Interest Period and bearing an interest rate equal to the Eurodollar Rate for such Interest Period.

8.7 Mitigation of Circumstances; Replacement of Banks. (a) Each Bank shall promptly notify the Company and the Administrative Agent of any event of which it has knowledge which will result in, and will use reasonable commercial efforts available to it (and not, in such Bank's sole judgment, otherwise disadvantageous to such Bank) to mitigate or avoid, (i) any obligation by the Company to pay any amount pursuant to Section 7.6 or 8.1 or (ii) the occurrence of any circumstances described in Section 8.2 or 8.3 (and, if any Bank has given notice of any such event described in clause (i) or (ii) above and thereafter such event ceases to exist, such Bank shall promptly so notify the Company and the Administrative Agent). Without limiting the foregoing, each Bank will designate a different funding office if such designation will avoid
(or reduce the cost to the Company of) any event described in clause (i) or (ii) of the preceding sentence and such designation will not, in such Bank's sole judgment, be otherwise disadvantageous to such Bank. No Bank shall request that the Company pay any amount pursuant to Section 7.6 or 8.1, or advise the Administrative Agent as to its determination under Section 8.2(b), unless it is generally making similar requests of, or determinations with respect to, other borrowers similarly situated, and each Bank agrees to use a reasonable basis for calculating such amounts and making such determinations.

(b) If the Company becomes obligated to pay additional amounts to any Bank pursuant to Section 7.6 or 8.1, or any Bank gives notice of the occurrence of any circumstances

32

described in Section 8.2 or 8.3, then, if no Event of Default has occurred and is continuing, the Company may designate a Replacement Bank to purchase the Loans of such Bank and such Bank's rights hereunder, without recourse to or warranty by, or expense to, such Bank, for a purchase price equal to the outstanding principal amount of the Loans payable to such Bank plus any accrued but unpaid interest on such Loans and all accrued but unpaid fees owed to such Bank and any other amounts payable to such Bank under this Agreement (excluding, however, in the event the aggregate Pro Rata Shares of the Banks being replaced are less than 25%, all amounts, if any, which otherwise would be payable to such Bank pursuant to Section 8.4 hereof), and to assume all the obligations of such Bank hereunder, and, upon such purchase and assumption (pursuant to an Assignment Agreement), such Bank shall no longer be a party hereto or have any rights hereunder (other than rights with respect to indemnities and similar rights applicable to such Bank prior to the date of such purchase and assumption) and shall be relieved from all obligations to the Company hereunder, and the Replacement Bank shall succeed to the rights and obligations of such Bank hereunder.

8.8 Conclusiveness of Statements; Survival of Provisions. Determinations and statements of any Bank pursuant to Section 8.1, 8.2, 8.3 or 8.4 shall be conclusive absent demonstrable error. Banks may use reasonable averaging and attribution methods in determining compensation under Sections 8.1 and 8.4, and the provisions of such Sections shall survive repayment of the Loans, cancellation of the Notes, expiration or termination of the Letters of Credit and termination of this Agreement.

The execution, delivery and performance by the Company of this Agreement and by each of the Company and each other Loan Party of each Loan Document to which it is a party, and the borrowings by the Company under this Agreement, do not and will not (i) require any consent or approval of any governmental agency or authority that

No contract or other agreement to which the Company or any Subsidiary is a party, the termination of which might reasonably be expected to have a Material Adverse Effect, has been terminated.

9.9 Taxes. Each of the Company and each Subsidiary has filed all tax returns and reports (federal, state, local, foreign and other applicable tax returns) required to be filed by or on behalf of it and has paid or caused to be paid all taxes and other governmental charges due for the periods covered thereby, including interest and penalties, other than any such taxes or charges

(a) Each Bank hereby irrevocably (subject to Section 13.9) appoints, designates and authorizes the Agents to take such action on its behalf under the provisions of this Agreement and each other Loan Document and to exercise such powers and perform such duties as are expressly delegated to it by the terms of this Agreement or any other Loan Document, together with such powers as are reasonably incidental thereto. Notwithstanding any provision to the contrary contained elsewhere in this Agreement or in any other Loan Document, no Agent shall have any duty or responsibility except those expressly set forth herein, nor shall any Agent have or be deemed to have any fiduciary relationship with any Bank, and no implied covenants, functions, responsibilities, duties, obligations or liabilities shall be read into this Agreement or any other Loan Document or otherwise exist against any Agent.

(b) The Issuing Bank shall act on behalf of the Banks with respect to any Letters of Credit issued by it and the documents associated therewith. The Issuing Bank shall have all of the benefits and immunities (i) provided to the Agents in this Section 13 with respect to any acts taken or omissions suffered by the Issuing Bank in connection with Letters of Credit issued by it or proposed to be issued by it and the applications and agreements for letters of credit pertaining to such Letters of Credit as fully as if the term "Agent", as used in this Section 13, included the Issuing Bank with respect to such acts or omissions and (ii) as additionally provided in this Agreement with respect to the Issuing Bank.

13.2 Delegation of Duties. Each Agent may execute any of its duties under this Agreement or any other Loan Document by or through agents, employees or attorneys-in-fact and shall be entitled to advice of counsel concerning all matters pertaining to such duties. No Agent shall be responsible for the negligence or misconduct of any agent or attorney-in-fact that it selects with reasonable care.

13.3 Liability of Agents. Neither any Agent nor any of its directors, officers, employees or other Person assisting them in their duties nor any employee or agent thereof shall (i) be liable for any action taken or omitted to be taken by any of them under or in connection with this Agreement or any other Loan Document or the transactions contemplated hereby

54

(except for its own gross negligence or willful misconduct), or (ii) be responsible in any manner to any of the Banks for any recital, statement, representation or warranty made by the Company or any Subsidiary or Affiliate of the Company, or any officer thereof, contained in this Agreement or in any other Loan Document, or in any certificate, report, statement or other document referred to or provided for in, or received by any Agent under or in connection with, this Agreement or any other Loan Document, or the validity, effectiveness, genuineness, enforceability or sufficiency of this Agreement or any other Loan Document, or for any failure of the Company or any other party to any Loan Document to perform its obligations hereunder or thereunder. No Agent shall be under any obligation to any Bank to ascertain or to inquire as to the observance or performance of any of the agreements contained in, or conditions of, this Agreement or any other Loan Document, or to inspect the properties, books or records of the Company or any of the Company's Subsidiaries or Affiliates.

13.4 Reliance by Agents. Each Agent shall be entitled to rely, and shall be fully protected in relying, upon any writing, resolution, notice, consent, certificate, affidavit, letter, telegram, facsimile, telex or telephone message, statement or other document or conversation believed by it to be genuine and correct and to have been signed, sent or made by the proper Person or Persons, and upon advice and statements of legal counsel (including counsel to the Company), independent accountants and other experts selected by such Agent. Each Agent shall be fully justified in failing or refusing to take any action under this Agreement or any other Loan Document unless it shall first receive such advice or concurrence of the Required Banks as it deems appropriate and, if it so requests, confirmation from the Banks of their obligation to indemnify such Agent against any and all liability and expense which may be incurred by it by reason of taking or continuing to take any such action. Each Agent shall in all cases be fully protected in acting, or in refraining from acting, under this Agreement or any other Loan Document in accordance with a request or consent of the Required Banks and such request and any action taken or failure to act pursuant thereto shall be binding upon all of the Banks.

13.5 Notice of Default. Each Bank hereby agrees that, upon learning of the existence of an Event of Default, it shall promptly notify the Administrative Agent. The Administrative Agent shall not be deemed to have knowledge or notice of the occurrence of any Event of Default or Unmatured Event of Default except with respect to defaults in the payment of principal, interest and fees required to be paid to the Administrative Agent for the account of the Banks, unless the Administrative Agent shall have received written notice from a Bank or the Company referring to this Agreement, describing such Event of Default or Unmatured Event of Default and stating that such notice is a "notice of default". The Administrative Agent will notify the Banks of its receipt of any such notice. The Administrative Agent shall take such action with respect to such Event of Default or Unmatured Event of Default as may be requested by the Required Banks in accordance with Section 12; provided that unless and until the Administrative Agent has received any such request, the Administrative Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Event of Default or Unmatured Event of Default as it shall deem advisable or in the best interest of the Banks.

13.6 Credit Decision. Each Bank acknowledges that the Agents have not made any representation or warranty to it, and that no act by the Agents hereafter taken, including any review of the affairs of the Company and its Subsidiaries, shall be deemed to constitute any

55

representation or warranty by any Agent to any Bank. Each Bank represents to the Agents that it has, independently and without reliance upon the Agents and based on such documents and information as it has deemed appropriate, made its own appraisal of and investigation into the business, prospects, operations, property, financial and other condition and creditworthiness of the Company and its Subsidiaries, and made its own decision to enter into this Agreement and to extend credit to the Company hereunder. Each Bank also represents that it will, independently and without reliance upon the Agents and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit analysis, appraisals and decisions in taking or not taking action under this Agreement and the other Loan Documents, and to make such investigations as it deems necessary to inform itself as to the business, prospects, operations, property, financial and other condition and creditworthiness of the Company. Except for notices, reports and other documents expressly herein required to be furnished to the Banks by the Administrative Agent, no Agent shall have any duty or responsibility to provide any Bank with any credit or other information concerning the business, prospects, operations, property, financial or other condition or creditworthiness of the Company which may come into the possession of such Agent.

13.7 Indemnification. Whether or not the transactions contemplated hereby are consummated, the Banks shall indemnify upon demand the Agent and its directors, officers, employees and any other Person assisting them in their duties or any employee or agent thereof (to the extent not reimbursed by or on behalf of the Company and without limiting the obligation of the Company to do so), pro rata, from and against any and all Indemnified Liabilities; provided that no Bank shall be liable for any payment to any such Person of any portion of the Indemnified Liabilities resulting from such Person's gross negligence or willful misconduct. Without limitation of the foregoing, each Bank shall reimburse the Agent upon demand for its ratable share of any costs or out-of-pocket expenses (including Attorney Costs) incurred by the Agent in connection with the preparation, execution, delivery, administration, modification, amendment or enforcement (whether through negotiations, legal proceedings or otherwise) of, or legal advice in respect of rights or responsibilities under, this Agreement, any other Loan Document, or any document contemplated by or referred to herein, to the extent that the Agent is not reimbursed for such expenses by or on behalf of the Company. The undertaking in this Section shall survive repayment of the Loans, cancellation of the Notes, expiration or termination of the Letters of Credit, termination of this Agreement and the resignation or replacement of the Agent.

13.8 Agents in Individual Capacity. LaSalle, National City and their respective Affiliates may make loans to, issue letters of credit for the account of, accept deposits from, acquire equity interests in and generally engage in any kind of banking, trust, financial advisory, underwriting or other business with the Company and its Subsidiaries and Affiliates as though LaSalle was not the Administrative Agent or the Issuing Bank hereunder, National City was not the Syndication Agent hereunder and without notice to or consent of the Banks. The Banks acknowledge that, pursuant to such activities, LaSalle, National City and their respective Affiliates may receive information regarding the Company or its Affiliates (including information that may be subject to confidentiality obligations in favor of the Company or such Affiliate) and acknowledge that no Agent shall be under any obligation to provide such information to them. With respect to their Loans (if any), LaSalle, National City and their respective Affiliates shall have the same rights and powers under this Agreement as any other

56

Bank and may exercise the same as though LaSalle was not the Administrative Agent and the Issuing Bank, National City was not the Syndication Agent, and the terms "Bank" and "Banks" include LaSalle, National City and their respective Affiliates, to the extent applicable, in their individual capacities.

13.9 Successor Agents. Any Agent may resign as an Agent upon 30 days' notice to the Banks. If an Agent resigns under this Agreement, the Required Banks shall, with (so long as no Event of Default exists) the consent of the Company (which shall not be unreasonably withheld or delayed), appoint from among the Banks a successor agent for the Banks. If no successor agent is appointed prior to the effective date of the resignation of an Agent, such Agent may appoint, after consulting with the Banks and the Company, a successor agent from among the Banks. Upon the acceptance of its appointment as successor agent hereunder, such successor agent shall succeed to all the rights, powers and duties of the retiring Agent and the terms "Administrative Agent," "Syndication Agent" and "Agent," as applicable, shall mean such successor agent, and the retiring Agent's appointment, powers and duties as an Agent shall be terminated. After any retiring Agent's resignation hereunder as an Agent, the provisions of this Section 13 and Sections 14.6 and 14.13 shall inure to its benefit as to any actions taken or omitted to be taken by it while it was an Agent under this Agreement. If no successor agent has accepted appointment as an Agent by the date which is 30 days following a retiring Agent's notice of resignation, the retiring Agent's resignation shall nevertheless thereupon become effective and the Banks shall perform all of the duties of the retiring Agent hereunder until such time, if any, as the Required Banks appoint a successor agent as provided for above.

13.10 Syndication Agent. There shall be no rights, obligations or liabilities afforded to or imposed upon the Syndication Agent by virtue of its status as such.

SECTION 14 GENERAL

14.1 Waiver; Amendments. No delay on the part of any Agent or any Bank in the exercise of any right, power or remedy shall operate as a waiver thereof, nor shall any single or partial exercise by any of them of any right, power or remedy preclude other or further exercise thereof, or the exercise of any other right, power or remedy. No amendment, modification or waiver of, or consent with respect to, any provision of this Agreement or the Notes shall in any event be effective unless the same shall be in writing and signed and delivered by the Required Banks, and then any such amendment, modification, waiver or consent shall be effective only in the specific instance and for the specific purpose for which given. No amendment, modification, waiver or consent shall change the Pro Rata Share of any Bank without the consent of such Bank. No amendment, modification, waiver or consent shall (i) increase the Revolving Loan Commitments except as contemplated by Section 2.7 as in effect on the date of this Agreement, (ii) extend the date for payment of any principal of or any interest on the Loans or any fees payable hereunder, (iii) reduce the principal amount of any Loan, the rate of interest thereon or any fees payable hereunder,
(iv) release the Guaranty, (v) alter the definition of "Required Banks" or "Pro Rata Share," (vi) amend this Section 14.1 or (vii) consent to any assignment or transfer by the Company or any of its Subsidiaries of any of its rights and obligations under this Agreement or any of the other Loan Documents without, in each case, the consent of all Banks (which consent shall not be unreasonably withheld in the case of a request for consent to a

57

Renewal Option). Notwithstanding the foregoing, the Required Banks may waive, compromise or extend the date for payment of any mandatory prepayment under
Section 6.2.2. No provision of Section 13 or other provision of this Agreement affecting any Agent in its capacity as such shall be amended, modified or waived without the consent of such Agent. No provision of this Agreement relating to the rights or duties of the Issuing Bank in its capacity as such shall be amended, modified or waived without the consent of the Issuing Bank. No amendment, modification, waiver or consent shall amend, modify, terminate or waive any provision hereof relating to the Swing Line Sublimit or the Swing Line Loans without the consent of the Swing Line Bank.

14.3 Notices. Except as otherwise provided in Sections 2.2.2 and 2.2.3, all notices hereunder shall be in writing (including facsimile transmission) and shall be sent to the applicable party at its address shown on Schedule 14.3 or at such other address as such party may, by written notice received by the other parties, have designated as its address for such purpose. Notices sent by facsimile transmission shall be deemed to have been given when sent; notices sent by mail shall be deemed to have been given three Business Days after the date when sent by registered or certified mail, postage prepaid; and notices sent by hand delivery or overnight courier service shall be deemed to have been given when received. For purposes of Sections 2.2.2 and 2.2.3, the Administrative Agent shall be entitled to rely on telephonic instructions from any person that the Administrative Agent in good faith believes is an authorized officer or employee of the Company, and the Company shall hold the Administrative Agent and each other Bank harmless from any loss, cost or expense resulting from any such reliance.

14.4 Computations. Where the character or amount of any asset or liability or item of income or expense is required to be determined, or any consolidation or other accounting computation is required to be made, for the purpose of this Agreement and the other Loan Documents, such determination or calculation shall, to the extent applicable and except as otherwise specified in this Agreement, be made in accordance with GAAP, consistently applied; provided that if the Company notifies the Administrative Agent that the Company wishes to amend any covenant in Section 10 to eliminate or to not take into account the effect of any change in GAAP on the operation of such covenant (or if the Administrative Agent notifies the Company that the Required Banks wish to amend
Section 10 for such purpose), then the Company's compliance with such covenant shall be determined on the basis of GAAP in effect immediately before the relevant change in GAAP became effective, until either such notice is withdrawn or such covenant is amended in a manner satisfactory to the Company and the Required Banks.

14.5 Regulation U. Each Bank represents that it in good faith is not relying, either directly or indirectly, upon any Margin Stock as collateral security for the extension or maintenance by it of any credit provided for in this Agreement.

Any Bank may, with the prior written consents of the Issuing Bank and the Administrative Agent and (so long as no Event of Default exists) the Company (which consents shall not be unreasonably delayed or withheld and, in any event, shall not be required for an assignment by a Bank to one of its Affiliates), at any time assign and delegate to one or more commercial banks or other Persons (any Person to whom such an assignment and delegation is to be made being herein called an "Assignee") all or any fraction of such Bank's Loans and Revolving Loan Commitment (which assignment and delegation shall be of a constant, and not a varying, percentage of all the assigning Bank's Loans and Revolving Loan Commitment) in a minimum aggregate amount equal to $5,000,000; provided that (a) no assignment and delegation may be made to any Person if, at the time of such assignment and delegation, the Company would be obligated to pay any greater amount under Section 7.6 or
Section 8 to the Assignee than the Company is then obligated to pay to the assigning Bank under such Sections (and if any assignment is made in violation of the foregoing, the Company will not be required to pay the incremental amounts) and (b) the Company and the Administrative Agent shall be entitled to continue to deal solely and directly with such Bank in connection with the interests so assigned and delegated to an Assignee until the date when all of the following conditions shall have been met:

59

(x) five Business Days (or such lesser period of time as the Administrative Agent and the assigning Bank shall agree) shall have passed after written notice of such assignment and delegation, together with payment instructions, addresses and related information with respect to such Assignee, shall have been given to the Company and the Administrative Agent by such assigning Bank and the Assignee,

(y) the assigning Bank and the Assignee shall have executed and delivered to the Company and the Administrative Agent an assignment agreement substantially in the form of Exhibit F (an "Assignment Agreement"), together with any documents required to be delivered thereunder, which Assignment Agreement shall have been accepted by the Administrative Agent, and

(z) except in the case of an assignment by a Bank to one of its Affiliates, the assigning Bank or the Assignee shall have paid the Administrative Agent a processing fee of $3,500.

From and after the date on which the conditions described above have been met,
(x) such Assignee shall be deemed automatically to have become a party hereto and, to the extent that rights and obligations hereunder have been assigned and delegated to such Assignee pursuant to such Assignment Agreement, shall have the rights and obligations of a "Bank" hereunder and (y) the assigning Bank, to the extent that rights and obligations hereunder have been assigned and delegated by it pursuant to such Assignment Agreement, shall be released from its obligations hereunder. Within five Business Days after effectiveness of any assignment and delegation, the Company shall execute and deliver to the Administrative Agent (for delivery to the Assignee and the Assignor, as applicable) a new Revolving Note in the principal amount of the Assignee's Pro Rata Share of the Revolving Loan Commitment, and, if the assigning Bank has retained a Revolving Loan Commitment hereunder, a replacement Revolving Note in the principal amount of the Pro Rata Share of the Revolving Loan Commitment retained by the assigning Bank (such Revolving Note to be in exchange for, but not in payment of, the predecessor Notes held by such assigning Bank). Each such Revolving Note shall be dated the effective date of such assignment. The assigning Bank shall mark each predecessor Revolving Note "exchanged" and deliver it to the Company. Accrued interest on that part of the predecessor Revolving Note being assigned shall be paid as provided in the Assignment Agreement. Accrued interest and fees on that part of the predecessor Revolving Note not being assigned shall be paid to the assigning Bank. Accrued interest and accrued fees shall be paid at the same time or times provided in the predecessor Revolving Note and in this Agreement. Any attempted assignment and delegation not made in accordance with this Section 14.9.1 shall be null and void.

Notwithstanding the foregoing provisions of this Section 14.9.1 or any other provision of this Agreement, any Bank may at any time assign all or any portion of its Loans and its Notes to a Federal Reserve Bank (but no such assignment shall release any Bank from any of its obligations hereunder).

14.9.2 Participations. Any Bank may, with the prior written consent of the Company (which consent (i) shall not be required if any Event of Default exists or for a sale of a participating interest by a Bank to one of its Affiliates and (ii) shall not be unreasonably delayed

60

or withheld), at any time sell to one or more commercial banks or other Persons participating interests in any Loan owing to such Bank, the Revolving Note held by such Bank, the Revolving Loan Commitment of such Bank, the direct or participation interest of such Bank in any Letter of Credit or any other interest of such Bank hereunder (any Person purchasing any such participating interest being herein called a "Participant"). In the event of a sale by a Bank of a participating interest to a Participant, (x) such Bank shall remain the holder of its Notes for all purposes of this Agreement, (y) the Company and the Administrative Agent shall continue to deal solely and directly with such Bank in connection with such Bank's rights and obligations hereunder and (z) all amounts payable by the Company shall be determined as if such Bank had not sold such participation and shall be paid directly to such Bank. No Participant shall have any direct or indirect voting rights hereunder except with respect to any of the events described in the fourth sentence of Section 14.1. Each Bank agrees to incorporate the requirements of the preceding sentence into each participation agreement which such Bank enters into with any Participant. The Company agrees that if amounts outstanding under this Agreement and the Notes are due and payable (as a result of acceleration or otherwise), each Participant shall be deemed to have the right of setoff in respect of its participating interest in amounts owing under this Agreement, any Note and with respect to any Letter of Credit to the same extent as if the amount of its participating interest were owing directly to it as a Bank under this Agreement or such Notes; provided that such right of setoff shall be subject to the obligation of each Participant to share with the Banks, and the Banks agree to share with each Participant, as provided in Section 7.5. The Company also agrees that each Participant shall be entitled to the benefits of Section 7.6 and Section 8 as if it were a Bank (provided that no Participant shall receive any greater compensation pursuant to Section 7.6 or Section 8 than would have been paid to the participating Bank if no participation had been sold).

14.10 Governing Law. This Agreement and each Note shall be a contract made under and governed by the internal laws of the State of Illinois applicable to contracts made and to be performed entirely within such State. Whenever possible each provision of this Agreement shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement shall be prohibited by or invalid under applicable law, such provision shall be ineffective to the extent of such prohibition or invalidity, without invalidating the remainder of such provision or the remaining provisions of this Agreement. All obligations of the Company and rights of the Agents and the Banks expressed herein or in any other Loan Document shall be in addition to and not in limitation of those provided by applicable law.

14.11 Counterparts. This Agreement may be executed in any number of counterparts and by the different parties hereto on separate counterparts and each such counterpart shall be deemed to be an original, but all such counterparts shall together constitute but one and the same Agreement.

14.12 Successors and Assigns. This Agreement shall be binding upon the Company, the Banks and the Agents and their respective successors and assigns, and shall inure to the benefit of the Company, the Banks and the Agents and the successors and assigns of the Banks and the Agents.

61

Commitments provided hereunder, the Company hereby agrees to indemnify, exonerate and hold each Agent, each Bank and each of the officers, directors, employees, Affiliates and agents of each Agent and each Bank (each a "Bank Party") free and harmless from and against any and all actions, causes of action, suits, losses, liabilities, damages and expenses, including Attorney Costs (collectively, the "Indemnified Liabilities"), incurred by the Bank Parties or any of them as a result of, or arising out of, or relating to (i) any tender offer, merger, purchase of stock, purchase of assets or other similar transaction financed or proposed to be financed in whole or in part, directly or indirectly, with the proceeds of any of the Loans, (ii) the use, handling, release, emission, discharge, transportation, storage, treatment or disposal of any hazardous substance at any property owned or leased by the Company or any Subsidiary, (iii) any violation of any Environmental Laws with respect to conditions at any property owned or leased by the Company or any Subsidiary or the operations conducted thereon, (iv) the investigation, cleanup or remediation of offsite locations at which the Company or any Subsidiary or their respective predecessors are alleged to have directly or indirectly disposed of hazardous substances, (v) claims of any Persons in connection with any of the Securities Laws and relating to the making of the Loans or the transactions contemplated by this Agreement and the other Loan Documents. or (vi) the execution, delivery, performance or enforcement of this Agreement or any other Loan Document by any of the Bank Parties, except for any such Indemnified Liabilities arising on account of the applicable Bank Party's gross negligence or willful misconduct. If and to the extent that the foregoing undertaking may be unenforceable for any reason, the Company hereby agrees to make the maximum contribution to the payment and satisfaction of each of the Indemnified Liabilities which is permissible under applicable law. All obligations provided for in this Section 14.13 shall survive repayment of the Loans, cancellation of the Notes, expiration or termination of the Letters of Credit, any foreclosure under, or any modification, release or discharge of any Guaranty and termination of this Agreement.

14.14 Nonliability of Lenders. The relationship between the Company on the one hand and the Banks and the Agents on the other hand shall be solely that of borrower and lender. Neither any Agent nor any Bank shall have any fiduciary responsibility to the Company. Neither any Agent nor any Bank undertakes any responsibility to the Company to review or inform the Company of any matter in connection with any phase of the Company's business or operations. The Company agrees that neither any Agent nor any Bank shall have liability to the Company (whether sounding in tort, contract or otherwise) for losses suffered by the Company in connection with, arising out of, or in any way related to the transactions contemplated and the relationship established by the Loan Documents, or any act, omission or event occurring in connection therewith, unless it is determined in a final non-appealable judgment by a court of competent jurisdiction that such losses resulted from the gross negligence or willful misconduct of the party from which recovery is sought. Neither any Agent nor any Bank shall have any liability with respect to, and the Company hereby waives, releases and agrees not to sue for, any special, indirect or consequential damages suffered by the Company in connection with, arising out of, or in any way related to the Loan Documents or the transactions contemplated thereby.

14.15 FORUM SELECTION AND CONSENT TO JURISDICTION. ANY LITIGATION BASED HEREON, OR ARISING OUT OF, UNDER, OR IN CONNECTION WITH THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT, SHALL BE BROUGHT AND MAINTAINED EXCLUSIVELY IN THE COURTS OF THE STATE OF ILLINOIS OR IN THE UNITED STATES DISTRICT COURT FOR THE NORTHERN DISTRICT OF

62

ILLINOIS; PROVIDED THAT ANY SUIT SEEKING ENFORCEMENT AGAINST ANY PROPERTY MAY BE BROUGHT, AT THE ADMINISTRATIVE AGENT'S OPTION, IN THE COURTS OF ANY JURISDICTION WHERE SUCH PROPERTY MAY BE FOUND. THE COMPANY HEREBY EXPRESSLY AND IRREVOCABLY SUBMITS TO THE JURISDICTION OF THE COURTS OF THE STATE OF ILLINOIS AND OF THE UNITED STATES DISTRICT COURT FOR THE NORTHERN DISTRICT OF ILLINOIS FOR THE PURPOSE OF ANY SUCH LITIGATION AS SET FORTH ABOVE. THE COMPANY FURTHER IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS BY REGISTERED MAIL, POSTAGE PREPAID, OR BY PERSONAL SERVICE WITHIN OR WITHOUT THE STATE OF ILLINOIS. THE COMPANY HEREBY EXPRESSLY AND IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY OBJECTION WHICH IT MAY NOW OR HEREAFTER HAVE TO THE LAYING OF VENUE OF ANY SUCH LITIGATION BROUGHT IN ANY SUCH COURT REFERRED TO ABOVE AND ANY CLAIM THAT ANY SUCH LITIGATION HAS BEEN BROUGHT IN AN INCONVENIENT FORUM.

14.16 Waiver of Jury Trial. EACH OF THE COMPANY, EACH AGENT AND EACH BANK HEREBY WAIVES ANY RIGHT TO A TRIAL BY JURY IN ANY ACTION OR PROCEEDING TO ENFORCE OR DEFEND ANY RIGHTS UNDER THIS AGREEMENT, ANY NOTE, ANY OTHER LOAN DOCUMENT AND ANY AMENDMENT, INSTRUMENT, DOCUMENT OR AGREEMENT DELIVERED OR WHICH MAY IN THE FUTURE BE DELIVERED IN CONNECTION HEREWITH OR THEREWITH OR ARISING FROM ANY BANKING RELATIONSHIP EXISTING IN CONNECTION WITH ANY OF THE FOREGOING, AND AGREES THAT ANY SUCH ACTION OR PROCEEDING SHALL BE TRIED BEFORE A COURT AND NOT BEFORE A JURY.

The foregoing restrictions on disclosure and use of Confidential Information shall not apply to any disclosure or use of any Confidential Information (i) in connection with any proposed assignment or participation permitted under Section 14.9, provided the Bank making such assignment or selling such participation has first obtained the Company's prior written consent to such disclosure or use, which consent shall not be unreasonably withheld so long as the prospective assignee or participant has agreed in writing to be bound by the provisions of this Section 14.17, (ii) which otherwise in its entirety is in the public domain, (iii) to the extent required by applicable law or any rule, regulation, decree, order or injunction of any foreign, federal, state, municipal or other government, or any department, commission, board, bureau, agency, public authority or instrumentality thereof or any court or arbitrator, but only after each Agent and each Bank shall have given, to the extent permitted by applicable law, the Company

63

written notice of such requirement and allowed the Company to contest such requirement, (iv) which is obtained by any Agent or any Bank from a third party not known to such Agent or such Bank to be under an obligation of confidentiality to the Company or (v) in connection with the enforcement by Administrative Agent and the Banks of their respective rights under this Agreement and the other Loan Documents, subject to the prior entry by the court in which such proceedings are pending of an appropriate order designed to afford the Company reasonable assurance such Confidential Information will be protected from unnecessary disclosure.

EMPLOYMENT AND TRANSITION AGREEMENT

This EMPLOYMENT AND TRANSITION AGREEMENT (the "Agreement"), is made and entered into on and effective as of November 3, 2003, (the "Effective Date") by MATTHEW NEVILLE, residing at 425 Easton Avenue, Geneva, Illinois, hereinafter referred to as "you," and Cabot Microelectronics Corporation, hereinafter referred to as "CMC" on behalf of themselves, their heirs, successors and assigns.

WHEREAS, you agree that you are entering into this Agreement voluntarily and have been advised to consult an attorney prior to signing it;

WHEREAS, you agree that the cash and other consideration provided pursuant to this Agreement is adequate consideration for the mutual terms, covenants and conditions of it, therefore, the parties do hereby agree as follows:

1. PURPOSE OF AGREEMENT. The parties have entered into this agreement to secure for CMC, the services of Matthew Neville in connection with the transition of CMC to new executive leadership and to obtain the benefit of his executive advice in light of his many years of service to CMC, to recognize his contributions to CMC as an employee, officer, director and as Chairman, and to clarify the rights and obligations of the parties following his decision to leave his position as Chairman, President, Chief Executive Officer and Director of CMC.

2. CONSIDERATION; TERM OF EMPLOYMENT. Upon the execution of this Agreement, CMC will:

a. Continue your employment for the two-year period beginning on the Effective Date and ending on the second anniversary of the Effective Date, November 3, 2005 (the "Extended Employment Term"). Your employment with CMC will be terminated on November 3, 2005, or earlier as otherwise may be specifically provided in this Agreement ("Termination Date").

b. During the Extended Employment Term, CMC will pay you an annual base salary equal to $400,000 in accordance with CMC's normal payroll practices, subject to normal withholding for state and federal taxes, FICA and other payroll deductions.

c. CMC will pay you a bonus of $300,000, for the fiscal year ended September 30, 2003, on or before December 12, 2003, subject to normal withholding for state and federal taxes, FICA and other payroll deductions.

d. Any and all non-qualified stock options ("NQSOs") granted to you pursuant to the Amended and Restated 2000 Equity Incentive Plan (the "EIP") and applicable Grant Agreements for such NQSOs previously vested or that become vested pursuant to their terms during the Extended Employment Term are and will remain exercisable only pursuant to the respective Grant Agreements and EIP. Schedule A hereto lists the NQSOs that have been granted, which shall continue to vest and be exercisable throughout the Extended Employment Term in accordance with the Grant Agreements for such NQSOs and the terms of the EIP.


You will not be eligible for any new or additional awards of stock options pursuant to the EIP or any other CMC stock option plan or program presently existing or adopted hereafter or for any new or additional deferral of income under any deferred compensation plan or program presently existing or adopted hereafter, including but not limited to the Short Term Bonus program. Other than as may be provided in any Grant Agreement for previously granted NQSOs or in the EIP, there will be no effect on any stock option heretofore awarded, whether or not such stock option has vested, nor shall there be any effect on any deferral of income that has already taken place. Following the Effective Date, you may exercise and sell your vested NQSOs in accordance with the terms of the EIP and applicable Grant Agreements, and the requirements of the securities laws of the United States, including laws relating to the purchase or sale of securities while in possession of material nonpublic information about CMC.

e. During the Extended Employment Term, you will be eligible to continue to participate in the health and welfare benefit programs that may be made generally available to employees of CMC in effect from time to time in accordance with the normal policies and practices of CMC, including CMC's group health, life and disability insurance programs. At the end of the Extended Employment Term, CMC will offer you the right to continue coverage under the CMC Group Welfare Benefit Plan in which you participated on the last day of the Extended Employment Term (so-called "COBRA coverage"). If you elect to continue your participation in the Group Welfare Benefit Plan under COBRA by signing and returning the COBRA election form to CMC at the end of the Extended Employment Term, for the eighteen month period following the end of the Extended Employment Term, CMC will pay the premium cost of your coverage and that of your eligible dependents under the Group Welfare Benefit Plan. CMC reserves the right to amend, modify, terminate or discontinue the health and welfare benefit programs provided to its employees, or the costs associated therewith, at any time.
