SECTION 1.01 The Merger. Upon the terms of this Agreement and subject to the conditions set forth in this Agreement, and in accordance with the DGCL, at the Effective Time (as defined below), as part of a single integrated plan, Merger Sub shall be merged with and into the Company, and as soon as practicable thereafter, the Company shall be merged with and into Parent. As a result of the Reverse Merger, the separate corporate existence of Merger Sub shall cease, and the Company shall continue as the surviving corporation of the Reverse Merger (the “Surviving Corporation”) and as a wholly-owned subsidiary of Parent. As a result of the Second-Step Merger, the separate corporate existence of the Company shall cease, and Parent shall continue as the surviving corporation.

SECTION 1.02 Effective Time; Closing. As promptly as practicable and in no event later than the second business day following the satisfaction or, if permissible, waiver of the conditions set forth in Article VII (or such other date as may be agreed in writing by each of the parties hereto), the parties hereto shall cause (a) the Reverse Merger to be consummated by filing a certificate of merger (the “Certificate of Merger”) with the Secretary of State of the State of Delaware in such form as is required by, and executed in accordance with, the relevant provisions of the DGCL and (b) the Second-Step Merger to be consummated by making all filings and recordings required under the DGCL. The term “Effective Time” means the date and time of the filing with, and the acceptance by, the Secretary of State of the State of Delaware of the Certificate of Merger (or such later time as may be agreed in writing by each of the parties hereto and specified in the Certificate of Merger). Immediately prior to the filing of the Certificate of Merger, a closing (the “Closing”) will be held at the offices of Gunderson Dettmer Stough Villeneuve Franklin & Hachigian, LLP (“Gunderson Dettmer”), 155 Constitution Drive, Menlo Park, California 94025 (or such other place as the parties hereto may agree). The date on which the Closing shall occur is referred to herein as the “Closing Date.”

SECTION 1.03 Effect of the Merger. At and after the Effective Time, the effect of the Reverse Merger shall be as provided in the applicable provisions of the DGCL. Without limiting the generality of the foregoing, and subject thereto, at the Effective Time, all the properties, rights, privileges, powers and franchises of each of the Company and Merger Sub shall vest in the Surviving Corporation, and all debts, liabilities, obligations, restrictions, disabilities and duties of each of the Company and Merger Sub shall become the debts, liabilities, obligations, restrictions, disabilities and duties of the Surviving Corporation, and, following the Second-Step Merger, all the properties, rights, privileges, powers and franchises of the Surviving Corporation shall vest in Parent, and all debts, liabilities, obligations, restrictions, disabilities and duties of the Surviving Corporation shall become the debts, liabilities, obligations, restrictions, disabilities and duties of Parent.

(a) At the Effective Time, the Certificate of Incorporation of the Company as the Surviving Corporation shall be amended to read the same as the Certificate of Incorporation of Merger Sub as in effect immediately prior to the Effective Time, except for such changes as may be determined by Parent and except that Article I of the Certificate of Incorporation of the Surviving Corporation, instead of reading the same as Article I of the Certificate of Incorporation of Merger Sub, shall read as follows: “The name of this corporation is FreeMarkets, Inc.,” or such other name as determined by Parent, and following the Second-Step Merger, the Certificate of Incorporation of Parent shall be the Certificate of Incorporation of the surviving corporation of the Second-Step Merger.

(b) At the Effective Time, the Bylaws of Merger Sub shall be the Bylaws of the Surviving Corporation (except that all references to Merger Sub in the Bylaws of the Surviving Corporation shall be changed to refer to such name as is set forth in the Certificate of Incorporation of the Surviving Corporation), and following the Second-Step Merger, the Bylaws of Parent shall be the Bylaws of the surviving corporation of the Second-Step Merger.

SECTION 1.05 Directors and Officers. The directors of Merger Sub immediately prior to the Effective Time shall be the directors of the Surviving Corporation, each to hold office in accordance with the Certificate of Incorporation and Bylaws of the Surviving Corporation, and the officers of Merger Sub immediately prior to the Effective Time shall be the officers of the Surviving Corporation, in each case until their respective successors are duly elected or appointed and qualified. The directors of Parent immediately prior to the Second-Step Merger shall be the initial directors of the surviving corporation of the Second-Step Merger, together with those directors appointed pursuant to Section 6.17 hereof, each to hold office in accordance with the Certificate of Incorporation and Bylaws of the surviving corporation of the Second-Step Merger, and the officers of Parent immediately prior to the Second-Step Merger shall be the initial officers of the surviving corporation of the Second-Step Merger, together with those officers appointed pursuant to Section 6.18 hereof, in each case until their respective successors are duly elected or appointed and qualified.

(a) At the Effective Time, by virtue of the Merger and without any action on the part of Parent, Merger Sub, the Company or the holders of any of the following securities:

(i) Each share of common stock of the Company, par value $0.01 per share (the “Company Common Stock”), (all issued and outstanding shares of Company Common Stock being hereinafter collectively referred to as the “Shares”), issued and outstanding immediately prior to the Effective Time (other than any Shares to be canceled pursuant to Section 2.01(a)(ii) and any Dissenting Shares (as defined in Section 2.06)) shall be converted, subject to Section 2.02(e), into the right to receive (x) 2.25 Parent Common Shares (the “Exchange Ratio”) and (y) $2.00 in cash (the “Per Share Cash Consideration”) (collectively, the number of Parent Common Shares equal to the Exchange Ratio and the Per Share Cash Consideration are referred to herein as the “Per Share Merger Consideration”). At the Effective Time, each such Share shall cease to be outstanding and cease to exist and each holder of Shares shall thereafter cease to have any rights with respect to such Shares, except the right to receive, without interest, Parent Common Shares and cash in accordance with this Section 2.01(a)(i) and cash for fractional Parent Common Shares in accordance with Section 2.02(e).

(ii) Each Share held in the treasury of the Company and each Share owned by Parent or any direct or indirect wholly owned subsidiary of Parent or of the Company immediately prior to the Effective Time shall be canceled and extinguished without any conversion thereof and no payment or distribution shall be made with respect thereto.

(iii) Each share of common stock of Merger Sub, par value $0.001 per share, issued and outstanding immediately prior to the Effective Time shall be converted into and exchanged for one duly authorized, validly issued, fully paid and nonassessable share of common stock, par value $0.001 per share, of the Surviving Corporation.

(i) If between the date of this Agreement and the Effective Time, the outstanding Parent Common Shares shall have been changed into a different number of shares or a different class, by reason of any stock dividend, subdivision, reclassification, recapitalization, split, combination or exchange of shares

or any similar event, the Exchange Ratio shall be correspondingly adjusted to the extent appropriate to reflect such stock dividend, subdivision, reclassification, recapitalization, split, combination or exchange of shares or similar event.

(ii) If between the date of this Agreement and the Effective Time, the outstanding shares of Company Common Stock shall have been changed into a different number of shares or a different class, by reason of any stock dividend, subdivision, reclassification, recapitalization, split, combination or exchange of shares or any similar event, the Exchange Ratio and the Per Share Cash Consideration shall be correspondingly adjusted to the extent appropriate to reflect such stock dividend, subdivision, reclassification, recapitalization, split, combination or exchange of shares or similar event.

(c) If any Shares outstanding immediately prior to the Effective Time are unvested or are subject to a repurchase option, risk of forfeiture or other condition under any applicable restricted stock purchase agreement or other agreement with the Company (each such share a “Restricted Company Share”), then (i) the cash and Parent Common Shares issued in exchange for such shares of Company Common Stock (the “Restricted Parent Shares”) will also be unvested and/or subject to the same repurchase option, risk of forfeiture or other condition, (ii) the certificates representing such Restricted Parent Shares may accordingly be marked with appropriate legends and (iii) the Company shall take all action that may be necessary to ensure that, from and after the Effective Time, Parent is entitled to exercise any such repurchase option or other right set forth in any such restricted stock purchase agreement or other agreement; provided that the repurchase price for each Restricted Parent Share shall equal the repurchase price for the Restricted Company Share divided by the Exchange Ratio. Cash and certificates representing the Restricted Parent Shares shall be held by Parent until such shares and cash are no longer subject to repurchase or forfeiture. Cash dividends on Restricted Parent Shares will be distributed to the holder of such Restricted Parent Shares on whose behalf the Restricted Parent Shares are being held by Parent. Any Parent Common Shares or other equity securities issued or distributed by Parent, including shares issued upon a stock dividend or split, in respect of Restricted Parent Shares (which remain restricted at the time of such distribution) will be subject to the same restrictions and other terms as the Restricted Parent Share with respect to which the distribution is made. Each holder of Restricted Parent Shares will have voting rights with respect to Restricted Parent Shares (and other voting securities) held by Parent on its behalf.

(a) Exchange Agent. Promptly following the Effective Time, Parent shall enter into an agreement (reasonably satisfactory to the Company) with EquiServe, or such other bank or trust company of recognized standing that may be designated by Parent and is reasonably satisfactory to the Company (the “Exchange Agent”). Promptly following the Effective Time, Parent shall deposit, or shall cause to be deposited, with the Exchange Agent, for the benefit of the holders of Shares, for exchange in accordance with this Article II through the Exchange Agent, (i) certificates representing the number of Parent Common Shares issuable pursuant to Section 2.01 and (ii) the amount of cash payable pursuant to Section 2.01 as of the Effective Time and cash from time to time as required to make payments in lieu of any fractional shares pursuant to Section 2.02(e) (such cash and certificates for Parent Common Shares, together with any dividends or distributions with respect thereto and together with such cash as may be required to make payments in lieu of any fractional shares, being hereinafter referred to as the “Exchange Fund”). The Exchange Agent shall, pursuant to irrevocable instructions, deliver (x) the Parent Common Shares and cash contemplated to be issued pursuant to Section 2.01 and (y) such cash as may be required to make payments in lieu of any fractional shares out of the Exchange Fund. Except as contemplated by Section 2.02(f) hereof, the Exchange Fund shall not be used for any other purpose.

(b) Exchange Procedures. As promptly as practicable after the Effective Time (and in no event later than two business days after the Effective Time), Parent shall cause the Exchange Agent to mail to each holder of record of a certificate or certificates which immediately prior to the Effective Time represented outstanding Shares (the “Certificates”) (i) a letter of transmittal (which shall be in customary form and shall

specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon proper delivery of the Certificates to the Exchange Agent) and (ii) instructions for use in effecting the surrender of the Certificates in exchange for cash and certificates representing Parent Common Shares (each as pursuant to Section 2.01) and cash in lieu of any fractional shares. Upon surrender to the Exchange Agent of a Certificate for cancellation, together with such letter of transmittal, duly executed and completed in accordance with the instructions thereto, and such other documents as may be reasonably required pursuant to such instructions, the holder of such Certificate shall be entitled to receive in exchange therefor (x) that amount of cash and a certificate representing that number of whole Parent Common Shares that such holder has the right to receive in respect of the Shares formerly represented by such Certificate (after taking into account all Shares then held by such holder) pursuant to Section 2.01 and (y) cash in lieu of any fractional Parent Common Shares to which such holder is entitled pursuant to Section 2.02(e) and any dividends or other distributions to which such holder is entitled pursuant to Section 2.02(c), and the Certificate so surrendered shall forthwith be canceled. In the event of a transfer of ownership of Shares that is not registered in the transfer records of the Company, the amount of cash and a certificate representing the number of Parent Common Shares to which such holder is entitled pursuant to Section 2.01, cash in lieu of any fractional Parent Common Shares to which such holder is entitled pursuant to Section 2.02(e) and any dividends or other distributions to which such holder is entitled pursuant to Section 2.02(c) may be issued to a transferee if the Certificate representing such Shares is presented to the Exchange Agent, accompanied by all documents required to evidence and effect such transfer and by evidence satisfactory to the Surviving Corporation that any applicable share transfer taxes have been paid. Until surrendered as contemplated by this Section 2.02, each Certificate (other than Certificates representing Dissenting Shares) shall be deemed at all times after the Effective Time to represent only the right to receive upon such surrender that amount of cash and a certificate representing that number of Parent Common Shares to which such holder is entitled pursuant to Section 2.01, cash in lieu of any fractional Parent Common Shares to which such holder is entitled pursuant to Section 2.02(e) and any dividends or other distributions to which such holder is entitled pursuant to Section 2.02(c).

(c) Distributions with Respect to Unexchanged Parent Common Shares. No dividends or other distributions with respect to the Parent Common Shares with a record date after the Effective Time shall be paid to the holder of any unsurrendered Certificate with respect to the Parent Common Shares entitled to be received upon surrender thereof, and no cash payment in lieu of any fractional shares shall be paid to any such holder pursuant to Section 2.02(e), until the holder of such Certificate shall surrender such Certificate as provided in Section 2.02(b). Subject to the effect of escheat, tax or other applicable Laws (as defined in Section 3.05(a)), following surrender of any such Certificate, there shall be paid to the holder of the certificates representing whole Parent Common Shares issued in exchange therefor (in addition to the Per Share Cash Consideration), without interest, (i) the amount of any cash payable with respect to a fractional Parent Common Share to which such holder is entitled pursuant to Section 2.02(e) and the amount of dividends or other distributions with a record date after the Effective Time and theretofore payable with respect to such whole Parent Common Shares and (ii) at the appropriate payment date, the amount of dividends or other distributions, with a record date after the Effective Time but prior to surrender and a payment date occurring after surrender, payable with respect to such whole Parent Common Shares.

(d) No Further Rights in Company Common Stock. All Parent Common Shares issued and cash paid upon conversion of the Shares in accordance with the terms hereof and any cash paid pursuant to Sections 2.02(c) or (e) shall be deemed to have been issued or paid in full satisfaction of all rights pertaining to such Shares.

(e) No Fractional Shares. No certificates or scrip representing fractional Parent Common Shares shall be issued upon the surrender for exchange of Certificates, and such fractional share interests will not entitle the owner thereof to vote or to any other rights of a stockholder of Parent. Each holder of a fractional share interest shall be paid an amount in cash (without interest and rounded up to the nearest whole cent) equal to the product obtained by multiplying (i) such fractional share interest to which such holder (after taking into account all fractional share interests then held by such holder) would otherwise be entitled by (ii) the

average closing price per share of Parent Common Shares for the ten most recent days that Parent Common Shares have traded ending on (and including) the trading day one day prior to the Effective Time, as reported on The Nasdaq National Market (with such average being calculated using the “simple average” methodology) (the “Parent Market Price”). As promptly as practicable after the determination of the amount of cash, if any, to be paid to holders of fractional share interests, the Exchange Agent shall so notify Parent, and Parent shall deposit such amount with the Exchange Agent and shall cause the Exchange Agent to forward payments to such holders of fractional share interests subject to and in accordance with the terms of Sections 2.02(b) and (c).

(f) Termination of Exchange Fund. Any portion of the Exchange Fund that remains undistributed to the holders of Shares for six months after the Effective Time shall be delivered to Parent, upon demand, and any holders of Shares who have not theretofore complied with this Article II shall thereafter look only to Parent for the cash and Parent Common Shares to which they are entitled pursuant to Section 2.01, any cash in lieu of fractional Parent Common Shares to which they are entitled pursuant to Section 2.02(e) and any dividends or other distributions with respect to the Parent Common Shares to which they are entitled pursuant to Section 2.02(c). Any portion of the Exchange Fund remaining unclaimed by holders of Shares as of a date that is immediately prior to such time as such amounts would otherwise escheat to or become property of any government entity shall, to the extent permitted by applicable Law, become the property of Parent free and clear of any claims or interest of any person previously entitled thereto.

(g) No Liability. To the fullest extent permitted by law, neither Parent nor the Surviving Corporation shall be liable to any holder of Shares for any Parent Common Shares (or dividends or distributions with respect thereto) or cash delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law.

(h) Withholding Rights. Each of the Surviving Corporation, Parent and the Exchange Agent shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any holder of Shares such amounts as it is required to deduct and withhold with respect to the making of such payment under the Code, or any provision of state, local or foreign tax Law. To the extent that amounts are so withheld by the Surviving Corporation, Parent or the Exchange Agent, as the case may be, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the Shares in respect of which such deduction and withholding was made by the Surviving Corporation, Parent or the Exchange Agent, as the case may be.

(i) Lost, Stolen or Destroyed Certificates. If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen or destroyed, and, if required by the Surviving Corporation or the Exchange Agent, the posting by such person of a bond, in such reasonable amount as the Surviving Corporation or Exchange Agent may direct, as indemnity against any claim that may be made against it with respect to such Certificate and the payment of any fee charged by the Exchange Agent for such service, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Certificate the amount of cash and number of Parent Common Shares to which the holder thereof is entitled pursuant to Section 2.01, any cash in lieu of fractional Parent Common Shares to which the holder thereof is entitled pursuant to Section 2.02(e) and any dividends or other distributions to which the holder thereof is entitled pursuant to Section 2.02(c).

SECTION 2.03 Stock Transfer Books. At the Effective Time, the stock transfer books of the Company shall be closed and there shall be no further registration of transfers of Shares thereafter on the records of the Company. From and after the Effective Time, the holders of Certificates representing Shares outstanding immediately prior to the Effective Time shall cease to have any rights with respect to such Shares, except as otherwise provided in this Agreement or by Law. On or after the Effective Time, any Certificates presented to the Exchange Agent or Parent for any reason shall be converted into the amount of cash and number of Parent Common Shares to which the holders thereof are entitled pursuant to Section 2.01, any cash in lieu of fractional Parent Common Shares to which the holders thereof are entitled pursuant to Section 2.02(e) and any dividends or other distributions to which the holders thereof are entitled pursuant to Section 2.02(c).

(a) At the Effective Time, Parent shall assume (i) all options to acquire Company Common Stock (the “Company Stock Options”) outstanding immediately prior to the Effective Time, whether or not exercisable and whether or not vested, under the Company’s 1996 Stock Option Plan (the “1996 Plan”), the Company’s Second Amended and Restated Stock Incentive Plan (the “Stock Incentive Plan”) and the Company’s 2001 Broad Based Equity Incentive Plan (the “Equity Incentive Plan” and together with the 1996 Plan and the Stock Incentive Plan, the “Company Stock Option Plans”), and (ii) each Company Stock Option Plan, and the Company’s repurchase right with respect to any unvested shares acquired by the exercise of Company Stock Options shall be assigned to Parent without any further action on the part of the Company or the holders of such unvested shares. Each Company Stock Option so assumed by Parent under this Agreement will continue to have, and be subject to, the same terms and conditions of such option immediately prior to the Effective Time (including, without limitation, any repurchase rights or vesting provisions), except that (A) each Company Stock Option will be exercisable (or will become exercisable in accordance with its terms) for that number of whole Parent Common Shares (rounded down to the nearest whole share) equal to (x) the number of shares of Company Common Stock subject to such Company Stock Option multiplied by (y) the Option Exchange Ratio; and (B) the per share exercise price for the Parent Common Shares issuable upon exercise of such assumed Company Stock Option will be equal to (x) the exercise price per share of such Company Stock Option in effect immediately prior to the Effective Time divided by (y) the Option Exchange Ratio (the exercise price per share, as so determined, being rounded upward to the nearest full cent). At or before the Effective Time, the Company shall cause to be effected any necessary amendments to the Company Stock Option Plans to give effect to the foregoing provisions of this Section 2.04. It is the intention of the parties that each Company Stock Option assumed by Parent shall qualify following the Effective Time as an incentive stock option as defined in section 422 of the Code to the extent permitted under section 422 of the Code and to the extent such option qualified as an incentive stock option prior to the Effective Time. Outstanding purchase rights under the Company’s Amended and Restated Employee Stock Purchase Plan (the “Company Purchase Plan”) shall be exercised upon the earlier of (i) the next scheduled purchase date under the Company Purchase Plan or (ii) immediately prior to the Effective Time, and each participant in the Company Purchase Plan shall accordingly be issued shares of Company Common Stock at that time pursuant to the terms of the Company Purchase Plan and each share of Company Common Stock so issued shall by virtue of the Merger, and without any action on the part of the holder thereof, be converted into the right to receive cash and Parent Common Shares in accordance with Section 2.01(a)(i) and cash for fractional Parent Common Shares in accordance with Section 2.02(e). The Company shall cause the Company Purchase Plan to be terminated as of the Effective Time.

For purposes of this Section 2.04, “Option Exchange Ratio” shall mean the quotient of (i) the sum of (A) the Per Share Cash Consideration and (B) the product of the Exchange Ratio and the Parent Market Price, and (ii) the Parent Market Price.

(b) As soon as practicable after the Effective Time (but in any event not later than 15 days following the Effective Time), Parent shall deliver to each person who, immediately prior to the Effective Time, was a holder of an outstanding Company Stock Option an appropriate notice setting forth such holder’s rights pursuant thereto and that the agreements evidencing the grants of such options shall continue in effect on the same terms and conditions (subject to the adjustments required by this Section 2.04 after giving effect to the Merger). At or before the Effective Time, Parent shall take all corporate action necessary to reserve for issuance a sufficient number of Parent Common Shares for delivery upon exercise of Company Stock Options assumed pursuant to this Section 2.04. As soon as practicable after the Effective Time (but in any event not later than 15 days following the Effective Time), Parent shall file a registration statement on Form S-8 (or any successor or other appropriate forms) that will register the Parent Common Shares subject to Company Stock Options to the extent permitted by federal securities laws and shall maintain the effectiveness of such registration statement or registration statements for so long as such options remain outstanding. In addition, Parent shall use all reasonable best efforts to cause the Parent Common Shares subject to Company Stock Options to be listed on The Nasdaq National Market and such exchanges as Parent shall determine.

(a) Notwithstanding any provision of this Agreement to the contrary, Shares that are outstanding immediately prior to the Effective Time and that are held by stockholders who have demanded and perfected appraisal rights for such Shares in accordance with the DGCL (collectively, the “Dissenting Shares”) shall not be converted into or represent the right to receive the applicable Parent Common Shares and cash. Such stockholders shall be entitled to receive payment of the appraised value of such shares of Company Common Stock held by them in accordance with the DGCL, unless and until such stockholders fail to perfect or effectively withdraw or otherwise lose their appraisal rights under the DGCL. All Shares held by stockholders who shall have failed to perfect or who shall have effectively withdrawn or lost their right to appraisal of such Shares under the DGCL shall thereupon be deemed to have been converted into and to have become exchangeable for, as of the Effective Time, the right to receive the amount of cash, without any interest thereon, and number of Parent Common Shares (and dividends or other distributions pursuant to Section 2.02(c), if any) to which such holder is entitled pursuant to Section 2.01 and cash in lieu of fractional shares, without any interest thereon, to which such holder is entitled pursuant to Section 2.02(e), upon the surrender, in the manner provided in Section 2.02, of the corresponding Certificate.

(b) The Company shall give Parent (i) prompt notice of any demands for appraisal received by the Company, withdrawals of such demands, and any other related instruments served pursuant to the DGCL and received by the Company and (ii) the opportunity to direct all negotiations and proceedings with respect to demands for appraisal under the DGCL. The Company shall not, except with the prior written consent of Parent, make any payment with respect to any demands for appraisal or offer to settle or settle any such demands.

The Company hereby represents and warrants to Parent and Merger Sub as of the date of this Agreement that the statements contained in this Article III are true and correct, subject to the exceptions set forth in the disclosure letter delivered by the Company to Parent and Merger Sub concurrently with the execution of this Agreement dated as of the date of this Agreement and certified by a duly authorized officer of the Company (the “Company Disclosure Letter”). The Company Disclosure Letter shall be arranged according to specific sections in this Article III and shall provide exceptions to, or otherwise qualify in reasonable detail, only the corresponding section in this Article III and any other section in this Article III where it is reasonably clear, upon a reading of such disclosure without any independent knowledge on the part of the reader regarding the matter disclosed, that the disclosure is intended to apply to such other section.

(a) Section 3.01(a) of the Company Disclosure Letter sets forth the jurisdiction of incorporation or organization of each of the Company and each subsidiary of the Company (collectively, the “Company Subsidiaries”). Each of the Company and the Company Subsidiaries is a corporation duly organized, validly existing and in good standing under the laws of the jurisdiction of such incorporation and has all requisite corporate power and authority and all necessary governmental approvals to own, lease and operate its properties and to carry on its business as it is now being conducted, except where the failure to have such governmental approvals has not had, and would not reasonably be expected to have, individually or in the aggregate, a Company Material Adverse Effect (as defined below). Each of the Company and the Company Subsidiaries is duly qualified or licensed as a foreign corporation or organization to do business, and is in good standing, in each jurisdiction where the character of the properties owned, leased or operated by it or the nature of its business makes such qualification or licensing necessary, except for such failures to be so

qualified or licensed and in good standing that have not had, and would not reasonably be expected to have, individually or in the aggregate, a Company Material Adverse Effect. The term “Company Material Adverse Effect” means any changes in or effects on the business of the Company or any Company Subsidiary that, individually or in the aggregate are, or would reasonably be expected to be, materially adverse to (A) the business, financial condition, assets (tangible or intangible) and liabilities (including contingent liabilities) considered as a whole or results of operations of the Company and the Company Subsidiaries, taken as a whole or (B) the ability of the Company to perform its obligations hereunder and consummate the Merger; provided, however, in no event shall any of the following be deemed to constitute, nor shall any of the following be taken into account in determining whether there has been or will be, a Company Material Adverse Effect: (i) any changes affecting the industry in which the Company and the Company Subsidiaries operate that do not have a disproportionate impact in any material respect on the Company and the Company Subsidiaries, taken as a whole, (ii) any changes in general economic conditions or the capital markets that do not disproportionately impact in any material respect the Company and the Company Subsidiaries, taken as a whole, (iii) in and of itself, any change in the market price or trading volume of Company Common Stock, (iv) in and of itself, a failure by the Company to meet the revenue or earnings predictions of equity analysts for any period ending (or for which earnings are released) on or after the date of this Agreement and prior to the Closing Date, (v) the taking of any action required by this Agreement or to which Parent has given its written consent, (vi) any changes or effects to the extent attributable to the announcement or the pendency of the transactions contemplated hereby, including disruption or loss of customer, business partner, supplier or employee relationships (provided that the exception in this clause (vi) shall not be used to excuse a breach of a representation or warranty of the Company contained in this Agreement that arises from the execution and delivery of this Agreement or the consummation of the transactions contemplated by this Agreement) or (vii) any changes or effects resulting from the actions of Parent or the Parent Subsidiaries. With respect to clauses (i) and (ii) of this paragraph (a), in determining whether any change has had a disproportionate impact on the Company and the Company Subsidiaries, taken as a whole, such impact shall be considered in the context of the impact incurred on comparable products and services and the businesses directly related thereto. With respect to clauses (iii) and (iv) of this paragraph (a), the term “in and of itself” means that the parties acknowledge that (A) the exception set forth in clauses (iii) and (iv) is not intended to prohibit Parent from claiming that any change, event or condition that causes such changes in the market price or trading volume of Company Common Stock or such failure to meet predictions constitutes a Company Material Adverse Effect, and (B) any, directly or indirectly, related change in the trading price of Company Common Stock on The Nasdaq National Market should not independently be used to judge the materiality of any such change, event or condition.

(b) Neither the Company nor any Company Subsidiary directly or indirectly owns any equity or similar interest in, or any interest convertible into or exchangeable or exercisable for, any corporation, partnership, joint venture or other business association or entity (other than the Company Subsidiaries in the case of the Company) that is or would reasonably be expected to be material to the Company and the Company Subsidiaries, taken as a whole.

SECTION 3.02 Certificate of Incorporation and Bylaws. The Company has heretofore made available to Parent a complete and correct copy of the Certificate of Incorporation and Bylaws of the Company, each as amended to the date of this Agreement. Such Certificate of Incorporation and Bylaws are in full force and effect. Neither the Company nor any Company Subsidiary is in violation of any of the provisions of its Certificate of Incorporation or Bylaws (or equivalent organizational documents).

(a) The authorized capital stock of the Company consists of 500,000,000 shares of Company Common Stock and 5,000,000 shares of preferred stock, par value $0.01 per share (the “Company Preferred Stock”). As of the date of this Agreement, (i) 42,265,987 shares of Company Common Stock are issued and outstanding, all of which are duly authorized, validly issued, fully paid and nonassessable, (ii) 145,564 shares of Company Common Stock and no shares of Company Preferred Stock are held in the treasury of

the Company, (iii) no shares of Company Common Stock or Company Preferred Stock are held by Company Subsidiaries and (iv) no shares of Company Preferred Stock are issued and outstanding. Each outstanding share of stock or other equity interest of each Company Subsidiary is duly authorized, validly issued, fully paid and nonassessable and each such share or other equity interest owned by the Company or another Company Subsidiary is free and clear of all liens, security interests, claims, pledges, options, rights of first refusal, agreements, limitations on voting rights, charges and other encumbrances of any nature whatsoever. The Company directly owns 100% of the issued and outstanding capital stock, and all options or other rights to acquire such capital stock, of each Company Subsidiary.

(b) The Company has duly reserved 7,000 shares of Company Common Stock for future issuance pursuant to the 1996 Plan, of which options to purchase 7,000 shares of Company Common Stock are outstanding as of the date of this Agreement, 13,154,183 shares of Company Common Stock for future issuance pursuant to the Stock Incentive Plan, of which options to purchase 10,391,746 shares of Company Common Stock are outstanding as of the date of this Agreement, and 2,482,760 shares of Company Common Stock for issuance to employees pursuant to the Equity Incentive Plan, of which options to purchase 2,235,444 shares of Company Common Stock are outstanding as of the date of this Agreement. The Company has provided to Parent a report dated as of December 31, 2003 that sets forth with respect to each Company Stock Option that is outstanding as of such date: (i) the name of the holder of such Company Stock Option; (ii) the total number of shares of Company Common Stock that was originally subject to such Company Stock Option, (iii) the number of shares of Company Common Stock that remain subject to such Company Stock Option; (iv) the date on which such Company Stock Option was granted, (v) the term of such Company Stock Option; (vi) the vesting schedule for such Company Stock Option; (vii) the vesting commencement date for such Company Stock Option; (viii) the exercise price per share of Company Common Stock purchasable under such Company Stock Option; and (ix) whether such Company Stock Option has been designated an “incentive stock option” as defined in section 422 of the Code. Section 3.03 of the Company Disclosure Letter sets forth a list of all Company Stock Options granted after December 31, 2003 through the date of this Agreement. No Company Stock Option will by its terms require an adjustment in connection with the Merger, except as contemplated by this Agreement. Neither the consummation of the transactions contemplated by this Agreement, nor any action taken or to be taken by the Company in connection with such transactions, will result in (i) any acceleration of exercisability or vesting (including, without limiting the foregoing, any right to acceleration of vesting that is contingent upon the occurrence of a subsequent event) in favor of any optionee under any Company Stock Option; (ii) any additional benefits for any optionee under any Company Stock Option; or (iii) the inability of Parent after the Effective Time to exercise any right or benefit held by the Company prior to the Effective Time with respect to any Company Stock Option assumed by Parent or any shares of Company Common Stock previously issued upon exercise of a Company Stock Option, including, without limitation, the right to repurchase an optionee’s unvested shares on termination of such optionee’s employment. The assumption by Parent of the Company Stock Option Plans and the Company Stock Options in accordance with Section 2.04 hereunder will not give rise to any event described in clauses (i) through (iii) of the immediately preceding sentence.

(c) The Company has duly reserved 1,400,000 shares of Company Common Stock for future issuance pursuant to the exercise of warrants to acquire Company Common Stock (“Warrants”). Section 3.03(c) of the Company Disclosure Letter sets forth, with respect to each Warrant issued to any person: (i) the name of the holder of such Warrant; (ii) the total number of shares of Company Common Stock that are subject to such Warrant; (iii) the total number of shares of Company Common Stock with respect to which such Warrant is immediately exercisable; (iv) the exercise price per share of Company Common Stock issuable under such Warrant; (v) whether such Warrant is subject to vesting and, if so, the conditions of such vesting; and (vi) the term of such Warrant.

(d) Except (i) for shares of Company Common Stock reserved for issuance under the Company Purchase Plan, the Company Stock Option Plans and pursuant to the exercise of Warrants and (ii) as provided in the Rights Plan (as defined in Section 3.27), there are no options, warrants or other rights, agreements, arrangements or commitments of any character relating to the issued or unissued capital stock

of the Company or any Company Subsidiary or obligating the Company or any Company Subsidiary to issue or sell any shares of its capital stock or other equity interests. The Company has no stockholders’ rights plan or similar plan in effect other than the Rights Plan. All shares of Company Common Stock so subject to issuance, upon issuance in accordance with the terms and conditions specified in the instruments pursuant to which they are issuable, will be duly authorized, validly issued, fully paid and nonassessable. There are no outstanding contractual obligations of the Company to repurchase, redeem or otherwise acquire any shares of capital stock or other equity interests of the Company or any Company Subsidiary. Each holder of a Company Stock Option or Warrant has been or will be given, or shall have properly waived, any required notice of the Merger prior thereto, and all such rights of notice will terminate at or prior to the Effective Time.

(e) All of the securities sold or issued by the Company and each Company Subsidiary have been sold or issued in compliance with the requirements of the federal securities laws and any other applicable securities laws.

SECTION 3.04 Authority Relative to This Agreement. The Company has all necessary corporate power and authority to execute and deliver this Agreement, and, subject to obtaining the necessary approvals of the Company’s stockholders, to perform its obligations hereunder and to consummate the Merger and the other transactions contemplated hereby. The execution and delivery of this Agreement by the Company and the consummation by the Company of the Merger and the other transactions contemplated hereby have been duly and validly authorized by all necessary corporate action and no other corporate proceedings on the part of the Company are necessary to authorize this Agreement or to consummate the Merger and the other transactions so contemplated (other than with respect to approval of the Merger and adoption of this Agreement by the Company’s stockholders by the affirmative vote of a majority of the outstanding shares of Company Common Stock (the “Company Stockholder Approval”), and the filing and acceptance of the Certificate of Merger as required by the DGCL).

(a) The execution and delivery of this Agreement by the Company do not, and the performance of this Agreement by the Company will not, (i) conflict with or violate the Certificate of Incorporation or Bylaws of the Company or any equivalent organizational documents of any Company Subsidiary, (ii) assuming that all consents, approvals, authorizations and other actions described in Section 3.05(b) have been obtained and all filings and obligations described in Section 3.05(b) have been made or complied with, conflict with or violate any foreign or domestic (federal, state or local) law, statute, ordinance, writ, rule, regulation, order, injunction, judgment or decree (“Law”) applicable to the Company or any Company Subsidiary or by which any property or asset of the Company or any Company Subsidiary is bound or affected, or (iii) result in any breach of or constitute a default (or an event which with notice or lapse of time or both would become a default) under, or give to others any right of termination, amendment, acceleration or cancellation of, trigger or change any rights or obligations under, or require any payment under, or result in the creation of a lien, claim, security interest or other charge or encumbrance on any property or asset of the Company or any

Company Subsidiary pursuant to, any note, bond, mortgage, indenture, contract, agreement, lease, license, permit, franchise or other instrument or obligation to which the Company or any Company Subsidiary is a party or by which any asset of the Company or any Company Subsidiary is bound or affected, except, with respect to clauses (ii) and (iii), for any such conflicts, violations, breaches, defaults or other occurrences that would not reasonably be expected to have, individually or in the aggregate, a Company Material Adverse Effect.

(b) The execution and delivery of this Agreement by the Company do not, and the performance of this Agreement by the Company will not, require any consent, approval, order, authorization, registration or permit of, or filing with or notification to, any domestic, foreign or supranational governmental, regulatory or administrative authority, agency or commission, any court, tribunal, or arbitral body, or any quasi-governmental or private body exercising regulatory, taxing, importing or other governmental authority (a “Governmental Entity”), except (i) for applicable requirements, if any, of the Securities Exchange Act of 1934, as amended (together with the rules and regulations promulgated thereunder, the “Exchange Act”), state securities or “blue sky” laws (“Blue Sky Laws”), The Nasdaq National Market, state takeover laws, the pre-merger notification requirements of the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and the rules and regulations thereunder (the “HSR Act”), any filings under similar competition or merger notification laws or regulations of foreign Governmental Entities and the filing and recordation of the Certificate of Merger as required by the DGCL, and (ii) for such other consents, approvals, orders, authorizations, registrations, permits, filings or notifications, which if not obtained or made would not reasonably be expected to be material to the Company or Parent or prevent or materially delay the consummation of the transactions contemplated by this Agreement.

(a) Each of the Company and the Company Subsidiaries is in possession of all material franchises, grants, authorizations, licenses, permits, easements, variances, exceptions, consents, certificates, approvals and orders of any Governmental Entity necessary for the Company or any Company Subsidiary to own, lease and operate its material properties or to carry on its business as it is now being conducted (the “Company Permits”), except where the failure to have any such Company Permit would not reasonably be expected to have a Company Material Adverse Effect.

(b) Neither the Company nor any Company Subsidiary is in conflict in any material respect with, or in default or violation in any material respect of, (i) any material Law applicable to the Company or any Company Subsidiary or by which any material property or asset of the Company or any Company Subsidiary is bound or affected, (ii) any material note, bond, mortgage, indenture, contract, agreement, lease, license, permit, franchise or other instrument or obligation to which the Company or any Company Subsidiary is a party or by which the Company or any Company Subsidiary or any material property or asset of the Company or any Company Subsidiary is bound or affected or (iii) any Company Permits.

(a) The Company has filed all forms, reports and documents required to be filed by it with the Securities and Exchange Commission (the “SEC”) since January 1, 2001 (collectively, the “Company SEC Reports”). As of the respective dates they were filed (and if amended or superseded by a filing prior to the date of this Agreement then on the date of such filing), (i) each Company SEC Report complied in all material respects with the requirements of the Securities Act of 1933, as amended (together with the rules and regulations promulgated thereunder, the “Securities Act”) or the Exchange Act, as the case may be, and (ii) none of the Company SEC Reports contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary in order to make the statements made therein, in the light of the circumstances under which they were made, not misleading. No Company Subsidiary is required to file any form, report or other document with the SEC or any similar Governmental Entity.

(b) Each of the consolidated financial statements (including, in each case, any notes thereto) contained in the Company SEC Reports (the “Company Financial Statements”) was prepared in accordance with generally accepted accounting principles (“GAAP”) applied on a consistent basis throughout the periods indicated (except as may be indicated in the notes thereto or, in the case of unaudited statements, as permitted by Form 10-Q of the SEC) and each presents fairly, in all material respects, the consolidated financial position, results of operations and cash flows of the Company and the consolidated Company Subsidiaries as at the respective dates thereof and for the respective periods indicated therein, except as otherwise noted therein (subject, in the case of unaudited statements, to normal and recurring year-end adjustments which would not reasonably be expected to, individually or in the aggregate, have a Company Material Adverse Effect). The most recent balance sheet of the Company contained in the Company SEC Reports as of September 30, 2003 is hereinafter referred to as the “Company Balance Sheet”.

(c) The Company has heretofore furnished to Parent a complete and correct copy of any amendments or modifications, which have not yet been filed with the SEC but which are required to be filed, to agreements, documents or other instruments that previously had been filed by the Company with the SEC pursuant to the Securities Act or the Exchange Act.

(d) The Company has established and maintained (i) disclosure controls and procedures (as defined in Rule 13a-15 promulgated under the Exchange Act) and (ii) internal controls over financial reporting (as defined in Rule 13a-15 promulgated under the Exchange Act). To Company’s knowledge, (i) such disclosure controls and procedures are effective to ensure that material information relating to the Company, including its consolidated subsidiaries, is made known to the Company’s senior management by others within those entities, particularly during the period when the Company’s periodic reports to which such information relates are required to be prepared, (ii) such internal controls over financial reporting provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles, (iii) there are no significant deficiencies or material weaknesses in the design or operation of Company’s internal controls which could adversely affect Company’s ability to record, process, summarize and report financial data and (iv) there is no fraud, whether or not material, that involves management or other employees who have a significant role in Company’s internal controls. Section 3.07(d) of the Company Disclosure Letter lists, and the Company has made available to Parent, complete and correct copies of, all formally written descriptions of, and all policies, manuals and other documents promulgating, such disclosure controls and procedures. As used in this Section 3.07, the term “file” shall be broadly construed to include any manner in which a document or information is furnished, supplied or otherwise made available to the SEC.

Except for (a) liabilities that are fully reflected or reserved against on the Company Balance Sheet, or in the notes thereto, and (b) liabilities incurred in the ordinary course of business consistent with past practice, since the date of the Company Balance Sheet, neither the Company nor any Company Subsidiary has incurred any liability of any nature whatsoever (whether absolute, accrued, contingent or otherwise and whether due or to become due) that would be material to the business, results of operations or financial condition of the Company and the Company Subsidiaries taken as a whole.

None of the Company, the Company Subsidiaries, or the directors and officers of the Company and the Company Subsidiaries in their capacity as such, nor any material property or asset of the Company or any Company Subsidiary is subject to any continuing order of, consent decree, settlement agreement or other similar written agreement with, or, to the knowledge of the Company, continuing investigation by, any Governmental Entity, or any order, writ, judgment, injunction, decree, determination or award of any Governmental Entity or arbitrator.

(a) Schedule 3.11(a) of the Company Disclosure Letter lists (i) all employee benefit plans (as defined in section 3(3) of ERISA) and all bonus, stock option, stock purchase, stock appreciation right, restricted stock, phantom stock, incentive, deferred compensation, executive compensation, cafeteria benefit, dependent care, director or employee loan, fringe benefit, sabbatical, retiree medical or life insurance, disability, supplemental retirement, employment, severance, termination pay or other benefit plans, programs or arrangements, including (without limitation) any arrangements that contain change of control or vesting acceleration provisions, whether legally enforceable or not, to which the Company or any Company Subsidiary is a party, with respect to which the Company or any Company Subsidiary has any obligation or which are maintained, contributed to or sponsored by the Company or any Company Subsidiary for the benefit of any current or former employee, officer or director of the Company or any Company Subsidiary, (ii) each employee benefit plan for which the Company or any Company Subsidiary could incur liability under section 4069 of ERISA in the event such plan has been or were to be terminated, (iii) any plan in respect of which the Company or any Company Subsidiary could incur liability under section 4212(c) of ERISA, and (iv) any contracts, arrangements or understandings between the Company or any Company Subsidiary and any employee or former employee of the Company or any Company Subsidiary including, without limitation, any contracts, arrangements or understandings relating to a sale of the Company (collectively, the “Company Benefit Plans”).

(b) Each Company Benefit Plan is in writing and the Company has made available to Parent a true and complete copy of each Company Benefit Plan and will furnish to Parent upon request a true and complete copy of each material document, if any, prepared in connection with each such Company Benefit Plan, including, without limitation, (i) a copy of each trust or other funding arrangement, (ii) each summary plan description and summary of material modifications, (iii) the three (3) most recent annual reports (Form 5500 series and all schedules and financial statements attached thereto), if any, required under ERISA or the Code

in connection with each Company Benefit Plan, (iv) the most recently received IRS determination letter for each such Company Benefit Plan, if such plan is intended to qualify under Section 401 of the Code, (v) any actuarial report and financial statement in connection with each such Company Benefit Plan for the three most recent plan years, (vi) any correspondence with the IRS or the Department of Labor with respect to each such Company Benefit Plan and (vii) each form of notice of grant or stock option agreement used to document Company Stock Options. There are no other employee benefit plans, programs, arrangements or agreements, whether formal or informal, whether in writing or not, to which the Company or any Company Subsidiary is a party, with respect to which the Company or any Company Subsidiary has any obligation or which are maintained, contributed to or sponsored by the Company or any Company Subsidiary for the benefit of any current or former employee, officer or director of the Company or any Company Subsidiary. Neither the Company nor any Company Subsidiary has express or implied commitment, whether legally enforceable or not, (x) to create, incur liability with respect to, or cause to exist, any other employee benefit plan, program or arrangement, (y) to enter into any contract or agreement to provide compensation or benefits to any individual, or (z) to modify, change or terminate any Company Benefit Plan, other than with respect to a modification, change or termination required by ERISA or the Code.

(c) None of the Company Benefit Plans is a multiemployer plan (within the meaning of section 3(37) or 4001(a)(3) of ERISA) (a “Multiemployer Plan”) or a single employer pension plan (within the meaning of section 4001(a)(15) of ERISA) for which the Company or any Company Subsidiary could incur liability under section 4063 or 4064 of ERISA (a “Multiple Employer Plan”). None of the Company Benefit Plans provides for or promises retiree medical, disability or life insurance benefits to any current or former employee, officer or director of the Company or any Company Subsidiary other than procedures intended to comply with the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended (“COBRA”). Each of the Company Benefit Plans is subject only to the Laws of the United States or a political subdivision thereof.

(d) None of the Company Benefit Plans provides for the payment of separation, severance, termination or similar-type benefits to any person or obligates the Company or any Company Subsidiary to pay separation, severance, termination or similar benefits solely or partially as a result of any transaction contemplated by this Agreement or as a result of a “change in ownership or control,” within the meaning of such term under section 280G of the Code. No amounts payable under the Company Benefit Plans solely as a result of the consummation of the transactions contemplated by this Agreement will fail to be deductible for federal income tax purposes by virtue of section 280G of the Code. There is no agreement, contract or arrangement to which the Company is a party that could, individually or collectively, result in the payment of any amount that would not be deductible by reason of sections 280G (as determined without regard to section 280G(b)(4)), 162 (other than 162(a)) or 404 of the Code. Neither the execution and delivery of this Agreement nor the consummation of the transactions contemplated hereby, either alone or together with another event, will (i) result in any payment (including, without limitation, severance, unemployment compensation, golden parachute, forgiveness of indebtedness or otherwise) becoming due under any Company Benefit Plan, (ii) increase any benefits otherwise payable or other obligations under any Company Benefit Plan or other arrangement, (iii) result in the acceleration of the time of payment, vesting or funding of any benefits including, but not limited to, the acceleration of the vesting and exercisability of any Company Stock Options, or (iv) affect in any material respects any Company Benefit Plan’s current treatment under any Laws including any tax or social contribution law. No Company Benefit Plan provides or reflects or represents any liability to provide retiree health to any person for any reason, except as may be required by COBRA or other applicable statute, and neither the Company nor any Company Subsidiary has represented, promised or contracted (whether in oral or written form) to any employee (either individually or to employees as a group) or any other person that such employee(s) or other person would be provided with retiree health, except to the extent required by statute.

(e) Each Company Benefit Plan is now and always has been operated in accordance in all material respects with its terms and the requirements of all applicable Laws, regulations and rules promulgated thereunder including, without limitation, ERISA, COBRA, the Family Medical Leave Act of 1993, as

amended (“FMLA”), and the Code. The Company and each Company Subsidiary has performed in all material respects all obligations required to be performed by it under, is not in any material respect in default under or in violation of, and has no knowledge of any default or violation by any party to, any Company Benefit Plan. No action, claim or proceeding is pending or, to the knowledge of the Company, threatened with respect to any Company Benefit Plan (other than claims for benefits in the ordinary course) and, to the knowledge of the Company, no fact or event exists that could give rise to any such action, claim or proceeding. Neither the Company nor any person that is a member of the same controlled group as the Company or under common control with the Company within the meaning of section 414 of the Code (each, an “ERISA Affiliate”) is subject to any penalty or tax with respect to any Company Benefit Plan under section 402(i) of ERISA or sections 4975 through 4980 of the Code. Each Company Benefit Plan can be amended, terminated or otherwise discontinued as of or after the Effective Time, without material liability to Parent, the Company or any of its ERISA Affiliates (other than ordinary administration expenses). Neither the Company nor any Company Subsidiary nor any affiliate has, prior to the Effective Time and in any material respect, violated any of the healthcare continuation requirements of COBRA, the requirements of FMLA, the requirements of the Health Insurance Portability and Accountability Act of 1996, the requirements of the Women’s Health and Cancer Rights Act of 1998, the requirements of the Newborns’ and Mothers’ Health Protection Act of 1996, or any amendment to each such act, or any similar provisions of state Law applicable to its employees.

(f) Each Company Benefit Plan intended to qualify under section 401(a) or section 401(k) of the Code and each trust intended to qualify under section 501(a) of the Code has either received a favorable determination, opinion, notification or advisory letter from the IRS with respect to each such Company Benefit Plan as to its qualified status under the Code, including all amendments to the Code effected by the Tax Reform Act of 1986 and subsequent legislation, and, to the knowledge of the Company, no fact or event has occurred since the date of such determination letter or letters from the IRS to adversely affect the qualified status of any such Company Benefit Plan or the exempt status of any such trust, or has remaining a period of time under applicable Treasury regulations or IRS pronouncements in which to apply for such a letter and make any amendments necessary to obtain a favorable determination as to the qualified status of each such Company Benefit Plan.

(g) Neither the Company nor any Company Subsidiary or ERISA Affiliate has any accumulated funding deficiency under section 412 of the Code or has incurred any liability under, arising out of or by operation of Title IV of ERISA (other than liability for premiums to the Pension Benefit Guaranty Corporation arising in the ordinary course), including, without limitation, any liability in connection with (i) the termination or reorganization of any employee benefit plan subject to Title IV of ERISA or (ii) the withdrawal from any Multiemployer Plan or Multiple Employer Plan, and, to the knowledge of the Company, no fact or event exists which could give rise to any such liability.

(h) Neither the Company nor any Subsidiary has, since January 1, 1998, terminated, suspended, discontinued contributions to or withdrawn from any employee pension benefit plan, as defined in section 3(2) of ERISA, including, without limitation, any multiemployer plan, as defined in section 3(37) of ERISA. All contributions, premiums or payments required to be made or accrued with respect to any Company Benefit Plan have been made on or before their due dates.

The Company has disclosed to Parent all material information relating to the business of the Company or any Company Subsidiary or the transactions contemplated by this Agreement.

Parent and Merger Sub hereby represent and warrant to the Company as of the date of this Agreement that the statements contained in this Article IV are true and correct, subject to the exceptions set forth in the disclosure letter delivered by Parent and Merger Sub to the Company concurrently with the execution of this Agreement dated as of the date of this Agreement and certified by a duly authorized officer of Parent (the “Parent Disclosure Letter”). The Parent Disclosure Letter shall be arranged according to specific sections in this Article IV and shall provide exceptions to, or otherwise qualify in reasonable detail, only the corresponding section in this Article IV and any other section in this Article IV where it is reasonably clear, upon a reading of such disclosure without any independent knowledge on the part of the reader regarding the matter disclosed, that the disclosure is intended to apply to such other section.

(a) Section 4.01(a) of the Parent Disclosure Letter sets forth the jurisdiction of incorporation of Parent and each subsidiary of Parent (the “Parent Subsidiaries”). Each of Parent and the Parent Subsidiaries is a corporation duly organized, validly existing and in good standing under the laws of such jurisdiction and has all requisite corporate power and authority and all necessary governmental approvals to own, lease and operate its properties and to carry on its business as it is now being conducted, except where the failure to have such governmental approvals has not had, and would not reasonably be expected to have, individually

or in the aggregate, a Parent Material Adverse Effect (as defined below). Each of Parent and the Parent Subsidiaries is duly qualified or licensed as a foreign corporation or organization to do business, and is in good standing, in each jurisdiction where the character of the properties owned, leased or operated by it or the nature of its business makes such qualification or licensing necessary, except for such failures to be so qualified or licensed and in good standing that have not had, and would not reasonably be expected to have, individually or in the aggregate, a Parent Material Adverse Effect. The term “Parent Material Adverse Effect” means any changes in or effects on the business of Parent or any Parent Subsidiary that, individually or in the aggregate are, or would reasonably be expected to be, materially adverse to (A) the business, financial condition, assets (tangible or intangible) and liabilities (including contingent liabilities) considered as a whole or results of operations of Parent and the Parent Subsidiaries, taken as a whole or (B) the ability of Parent to perform its obligations hereunder and consummate the Merger; provided, however, in no event shall any of the following be deemed to constitute, nor shall any of the following be taken into account in determining whether there has been or will be, a Parent Material Adverse Effect: (i) any changes affecting the industry in which Parent and the Parent Subsidiaries operate that do not have a disproportionate impact in any material respect on the Parent and the Parent Subsidiaries, taken as a whole, (ii) any changes in general economic conditions or the capital markets that do not disproportionately impact in any material respect Parent and the Parent Subsidiaries, taken as a whole, (iii) in and of itself, any change in the market price or trading volume of Parent Common Shares, (iv) in and of itself, a failure by Parent to meet the revenue or earnings predictions of equity analysts for any period ending (or for which earnings are released) on or after the date of this Agreement and prior to the Closing Date, (v) the taking of any action required by this Agreement or to which the Company has given its written consent, (vi) any changes or effects to the extent attributable to the announcement or the pendency of the transactions contemplated hereby, including disruption or loss of customer, business partner, supplier or employee relationships (provided that the exception in this clause (vi) shall not be used to excuse a breach of a representation or warranty of Parent or Merger Sub contained in this Agreement that arises from the execution and delivery of this Agreement or the consummation of the transactions contemplated by this Agreement) or (vii) any changes or effects resulting from the actions of the Company or the Company Subsidiaries. With respect to clauses (i) and (ii) of this paragraph (a), in determining whether any change has had a disproportionate impact on the Parent and the Parent Subsidiaries, taken as a whole, such impact shall be considered in the context of the impact incurred on comparable products and services and the businesses directly related thereto. With respect to clauses (iii) and (iv) of this paragraph (a), the term “in and of itself” means that the parties acknowledge that (A) the exception set forth in clauses (iii) and (iv) is not intended to prohibit the Company from claiming that any change, event or condition that causes such changes in the market price or trading volume of Parent Common Shares or such failure to meet predictions constitutes a Parent Material Adverse Effect, and (B) any, directly or indirectly, related change in the trading price of Parent Common Shares on The Nasdaq National Market should not independently be used to judge the materiality of any such change, event or condition.

(b) Neither Parent nor any Parent Subsidiary directly or indirectly owns any equity or similar interest in, or any interest convertible into or exchangeable or exercisable for, any corporation, partnership, joint venture or other business association or entity (other than the Parent Subsidiaries in the case of Parent) that is or would reasonably be expected to be material to Parent and the Parent Subsidiaries, taken as a whole.

(b) The execution and delivery of this Agreement by each of Parent and Merger Sub do not, and the performance of this Agreement by each of Parent and Merger Sub will not, require any consent, approval, order, authorization, registration or permit of, or filing with or notification to, any Governmental Entity, except (i) for applicable requirements, if any, of the Exchange Act, Blue Sky Laws, the Securities Act, The Nasdaq National Market, state takeover laws, the pre-merger notification requirements of the HSR Act, any filings under similar competition or merger notification laws or regulations of foreign Governmental Entities and the filing and recordation of the Certificate of Merger as required by the DGCL, and as set forth in Section 4.05(b) of the Parent Disclosure Letter and (ii) for such other consents, approvals, orders, authorizations, registrations, permits, filings or notifications which if not obtained or made would not reasonably be expected to be material to the Company or Parent or to prevent or materially delay the consummation of the transactions contemplated by this Agreement.

(a) Each of Parent and the Parent Subsidiaries is in possession of all material franchises, grants, authorizations, licenses, permits, easements, variances, exceptions, consents, certificates, approvals and orders of any Governmental Entity necessary for Parent or any Parent Subsidiary to own, lease and operate its material properties or to carry on its business as it is now being conducted (the “Parent Permits”), except where the failure to have any such Parent Permit would not reasonably be expected to have a Parent Material Adverse Effect.

(b) Neither Parent nor any of the Parent Subsidiaries is in conflict in any material respect with, or in default or violation in any material respect of any Law applicable to Parent or the Parent Subsidiaries or by which any material property or asset of Parent or the Parent Subsidiaries is bound or affected.

(a) Parent has filed all forms, reports and documents required to be filed by it with the SEC since January 1, 2001 (collectively, the “Parent SEC Reports”). As of the respective dates they were filed (and if amended or superseded by a filing prior to the date of this Agreement then on the date of such filing), (i) each Parent SEC Report complied in all material respects with the requirements of the Securities Act or the Exchange Act, as the case may be, and (ii) none of the Parent SEC Reports contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary in order to make the statements made therein, in the light of the circumstances under which they were made, not misleading. No Parent Subsidiary is required to file any form, report or other document with the SEC or any similar Governmental Entity.

(b) Each of the consolidated financial statements (including, in each case, any notes thereto) contained in the Parent SEC Reports (the “Parent Financial Statements”) was prepared in accordance with GAAP applied on a consistent basis throughout the periods indicated (except as may be indicated in the notes thereto or, in the case of unaudited statements, as permitted by Form 10-Q of the SEC) and each presents fairly, in all material respects, the consolidated financial position, results of operations and cash flows of Parent and the consolidated Parent Subsidiaries as at the respective dates thereof and for the respective periods indicated therein, except as otherwise noted therein (subject, in the case of unaudited statements, to normal and recurring year-end adjustments which would not reasonably be expected to, individually or in the aggregate, have a Parent Material Adverse Effect). The most recent balance sheet of Parent contained in the Parent SEC Reports as of September 30, 2003 is hereinafter referred to as the “Parent Balance Sheet.”

(c) Parent has heretofore furnished to the Company a complete and correct copy of any amendments or modifications, which have not yet been filed with the SEC but which are required to be filed, to agreements, documents or other instruments which previously had been filed by Parent with the SEC pursuant to the Securities Act or the Exchange Act.

(d) Parent has established and maintained (i) disclosure controls and procedures (as defined in Rule 13a-15 promulgated under the Exchange Act) and (ii) internal controls over financial reporting (as defined in Rule 13a-15 promulgated under the Exchange Act). To Parent’s knowledge, (i) such disclosure controls and procedures are effective to ensure that material information relating to Parent, including its consolidated subsidiaries, is made known to Parent’s senior management by others within those entities, particularly during the period when Parent’s periodic reports to which such information relates are required to be prepared, (ii) such internal controls over financial reporting provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles, (iii) there are no significant deficiencies or material weaknesses in the design or operation of Parent’s internal controls which could adversely affect Parent’s ability to record, process, summarize and report financial data and (iv) there is no fraud, whether or not material, that involves management or other employees who have a significant role in Parent’s internal controls. Section 4.07(d) of the Parent Disclosure Letter lists, and Parent has made available to the Company, complete and correct copies of, all formally written descriptions of, and all policies, manuals and other documents promulgating, such disclosure controls and procedures. As used in this Section 4.07, the term “file” shall be broadly construed to include any manner in which a document or information is furnished, supplied or otherwise made available to the SEC.

(e) Neither Parent nor any of Parent’s current or former officers or directors are the subject of an SEC investigation or enforcement action.

SECTION 4.08 Tax Matters. To the knowledge of Parent, neither Parent nor any of its affiliates has taken or agreed to take any action that would prevent the Merger from qualifying as a reorganization within the meaning

of section 368(a) of the Code or that would prevent the Alternative Double Merger Transaction (as defined in Section 6.21) from qualifying for tax-free treatment (either as a reorganization as defined in Section 368(a) of the Code, a transfer to a corporation controlled by the transferor within the meaning of Section 351(a) of the Code, or a combination of both). Parent is not aware of any agreement, plan or other circumstance that would prevent the Merger from qualifying as a reorganization within the meaning of Section 368(a) of the Code or that would prevent the Alternative Double Merger Transaction (as defined in Section 6.21) from qualifying for tax-free treatment (either as a reorganization as defined in Section 368(a) of the Code, a transfer to a corporation controlled by the transferor within the meaning of Section 351(a) of the Code, or a combination of both).

(b) The affirmative vote at the Parent Stockholders’ Meeting (as defined in Section 6.01(a) below) of a majority of the total votes cast in person or by proxy on the proposal to approve the issuance of Parent Common Shares pursuant to the Merger (the “Parent Share Issuance Stockholder Approval”) is the only vote of the holders of any class or series of Parent’s capital stock necessary to approve the transactions contemplated by this Agreement.

SECTION 4.12 Undisclosed Liabilities. Except for (a) liabilities that are fully reflected or reserved against on the Parent Balance Sheet, or in the notes thereto, and (b) liabilities incurred in the ordinary course of business consistent with past practice that are not, individually or in the aggregate, reasonably expected to have a Parent Material Adverse Effect, since the date of the Parent Balance Sheet, Parent has not incurred any liability of any nature whatsoever (whether absolute, accrued, contingent or otherwise and whether due or to become due).

Neither Parent nor any Parent Subsidiary nor any material property or asset of Parent or any Parent Subsidiary is subject to any continuing order of, consent decree, settlement agreement or other similar written agreement with, or, to the knowledge of Parent, continuing investigation by, any Governmental Entity, or any order, writ, judgment, injunction, decree, determination or award of any Governmental Entity or arbitrator that in any case would reasonably be expected to have a Parent Material Adverse Effect.

With respect to patent rights, moral rights and Mark rights, the representations and warranties of this Section 4.16(a) are made only to Parent’s and the Parent Subsidiaries’ knowledge.

(g) None of Parent or the Parent Subsidiaries is aware that any of its employees or contractors is obligated under any Employee Obligation that would reasonably be expected to interfere with or conflict with any of the businesses of Parent and the Parent Subsidiaries as currently conducted. Neither the execution nor delivery of this Agreement nor the conduct of Parent’s business as currently conducted, will, to Parent’s or any Parent Subsidiary’s knowledge, conflict with or result in a breach of the terms, conditions or provisions of, or constitute a default under, any Employee Obligation.

Section 4.20(a) of the Parent Disclosure Letter lists all real property leases to which Parent or any Parent Subsidiary is a party and each amendment thereto. All such current leases are in full force and effect, are valid and effective in accordance with their respective terms, and, to Parent’s knowledge, there is not, under any of such leases, any existing default or event of default (or event which with notice or lapse of time, or both, would constitute a default) that would give rise to a material claim.

(b) Each of Parent and the Parent Subsidiaries has good and valid title to, or, in the case of leased properties, valid leasehold interests in, all of its material tangible personal property, used or held for use in its business, free and clear of any Liens except for Liens (i) imposed by Law in respect of obligations not yet due that are owed in respect of taxes or which otherwise are owed to carriers, warehouse persons or laborers, (ii) reflected in the financial statements contained in the Parent SEC Reports and (iii) which are not material in character, amount or extent, and which do not materially detract from the value, or materially interfere with the present or contemplated use, of the property subject thereto or affected thereby.

SECTION 4.21 Insurance. Parent has provided or made available to the Company true, correct and complete copies of all policies of insurance to which each of Parent and the Parent Subsidiaries are a party or are a beneficiary or named insured. There is no material claim pending under any of such policies as to which coverage has been questioned, denied or disputed by the underwriters of such policies.

Parent has no knowledge of any threatened termination of, or material premium increase with respect to, any of such policies.

Parent and the Parent Subsidiaries have performed in all material respects all material obligations required to be performed by them under, are not in material default under or in material violation of, and have no knowledge of any material default or material violation by any party to, any Parent Employee Benefit Plans. No material action, claim or proceeding is pending or, to the knowledge of Parent, threatened with respect to any Parent Employee Benefit Plans (other than claims for benefits in the ordinary course).

SECTION 4.23 Interested Party Transactions. No director, officer or other affiliate of Parent (or any member of the immediate family of any of the foregoing persons) has or has had, directly or indirectly, (i) an economic interest in any person that has furnished or sold, or furnishes or sells, services or products that Parent or any Subsidiary furnishes or sells, or proposes to furnish or sell; (ii) an economic interest in any person that purchases from or sells or furnishes to, Parent or any Subsidiary, any goods or services; (iii) a beneficial interest in any Contract included in the Parent Disclosure Letter; or (iv) any contractual or other arrangement with Parent or any Subsidiary; provided, however, that ownership of no more than one percent (1%) of the outstanding voting stock of a publicly traded corporation shall not be deemed an “economic interest in any person” for purposes of this Section 4.23. Parent and the Parent Subsidiaries have not, since September 30, 2003, (i) extended or maintained credit, arranged for the extension of credit or renewed an extension of credit in the form of a personal loan to or for any director or executive officer (or equivalent thereof) of Parent, or (ii) materially modified any term of any such extension or maintenance of credit. There are no extensions of credit maintained by Parent or any of the Parent Subsidiaries to which the second sentence of Section 13(k)(1) of the Exchange Act applies. No officer or director of Parent or any Parent Subsidiary has asserted any claim, charge, action or cause of action against Parent or any Parent Subsidiary, except for immaterial claims for accrued vacation pay, accrued benefits under any employee benefit plan and similar matters and agreements existing on the date hereof.

SECTION 4.24 No Illegal Payments. Neither Parent nor any Parent Subsidiary, nor any director, officer, agent employee or other person acting on behalf of Parent or any Parent Subsidiary, has used any corporate or other funds for unlawful contributions, payments, gifts or entertainment, or made any unlawful expenditures relating to political activity to government officials or others or established or maintained any unlawful or unrecorded funds in violation of Section 30A of the Exchange Act. Neither Parent nor any Parent Subsidiary, nor any current director, officer, agent, employee or other person acting on behalf of Parent or any Parent Subsidiary has accepted or received any unlawful contributions, payments, gifts or expenditures.

SECTION 4.25 No Misstatements. No representation or warranty made by Parent, Merger Sub or any Parent Subsidiary in this Agreement, the Parent Disclosure Letter or any certificate delivered or deliverable pursuant to the terms hereof contains or will contain any untrue statement of a material fact, or omits, or will omit, when taken as a whole, any material fact, necessary in order to make the statements made, in light of the circumstances under which they were made, not misleading. Parent has disclosed to the Company all material information relating to the business of Parent, Merger Sub or any Parent Subsidiary or the transactions contemplated by this Agreement.

SECTION 5.01 Conduct of Business by the Company Pending the Merger. The Company agrees that, between the date of this Agreement and the Effective Time, except as set forth in Section 5.01 of the Company Disclosure Letter or as specifically contemplated by any other provision of this Agreement, unless Parent shall otherwise consent in writing:

(a) As promptly as practicable after the execution of this Agreement, (i) Parent and the Company shall prepare and file with the SEC a joint proxy statement (together with any amendments thereof or supplements thereto, the “Joint Proxy Statement”) relating to the respective meetings of the Company’s stockholders (the “Company Stockholders’ Meeting”) to be held to consider approval of the Merger and adoption of this Agreement and of the Parent stockholders (the “Parent Stockholders’ Meeting”) to be held to obtain (x) the Parent Share Issuance Stockholder Approval and (y) the approval of the stockholders of Parent to adopt an amendment to Parent’s Certificate of Incorporation to effect a reverse split of the Parent Common Shares, in a ratio of either 1-for-5 or 1-for-6 (any such split, the “Parent Reverse Stock Split”), and (ii) Parent shall prepare and file with the SEC a registration statement on Form S-4 (together with all amendments thereto, the ”Registration Statement”) in which the Joint Proxy Statement shall be included as a prospectus, in connection with the registration under the Securities Act of the Parent Common Shares to be issued to the stockholders of the Company pursuant to the Merger. Each of Parent and the Company shall use its reasonable best efforts to cause the Registration Statement to become effective as promptly as practicable and, prior to the effective date of the Registration Statement, Parent shall use its reasonable best efforts to take all or any action required under any applicable federal or state securities laws in connection

with the issuance of Parent Common Shares pursuant to the Merger. Each of Parent and the Company shall furnish all information concerning itself as the other may reasonably request in connection with such actions and the preparation of the Registration Statement and Joint Proxy Statement. As promptly as practicable after the Registration Statement shall have become effective, each of Parent and the Company shall mail the Joint Proxy Statement to their respective stockholders.

For purposes of this Agreement, such recommendation of the Board of Directors shall be deemed to have been modified in a manner adverse to Parent if such recommendation shall no longer be unanimous.

(c) Prior to the adoption and approval of this Agreement and the approval of the Merger by the requisite vote of the stockholders of the Company, nothing in this Agreement shall prevent the Company’s Board of Directors from withholding, withdrawing, amending, modifying or changing its unanimous recommendation in favor of the Merger if (i) a Superior Proposal (as defined in Section 6.05 below) is made to the Company and is not withdrawn, (ii) the Company shall have provided written notice to Parent as promptly as practicable (and, in any event, within one business day) advising Parent that the Company has received a Superior Proposal, specifying the terms and conditions of such Superior Proposal in reasonable detail and identifying the person or entity making such Superior Proposal (a “Notice of Superior Proposal”), (iii) Parent shall not have, within three business days of Parent’s receipt of the Notice of Superior Proposal, made an offer that the Company’s Board of Directors determines in its good faith judgment to be at least as favorable to the Company and its stockholders as such Superior Proposal (it being agreed that the Company’s Board of Directors shall convene a meeting to consider any such offer by Parent promptly following the receipt thereof), (iv) the Board of Directors of the Company concludes in good faith, after consultation with its outside legal counsel, that, in light of such Superior Proposal, the withholding, withdrawal, amendment, modification or change of such recommendation is required in order for the Board of Directors of the Company to comply with its fiduciary obligations to the Company and its stockholders under applicable Law and (v) the Company shall not have violated any of the restrictions set forth in Section 6.05 or this Section 6.01(c). The Company shall use its commercially reasonable efforts to provide Parent with at least two business days’ notice of any meeting of the Company’s Board of Directors at which the Company’s Board of Directors is reasonably expected to consider any Competing Transaction (as defined in Section 6.05 below).

(d) The Joint Proxy Statement shall include the unanimous recommendation of the Board of Directors of Parent to the stockholders of Parent to vote in favor of approving (i) the issuance of the Parent Common Shares pursuant to the Merger and (ii) the Parent Reverse Stock Split and neither the Board of Directors of Parent nor any committee thereof shall withhold, withdraw, amend, modify or change, or propose or resolve to withhold, withdraw, amend, modify or change, in each case in a manner adverse to the Company, the unanimous recommendation of the Board of Directors of Parent that the stockholders of Parent vote in favor of and approve the issuance of the Parent Common Shares pursuant to the Merger; provided, however, that the foregoing shall not prohibit the Board of Directors of Parent from fulfilling its duty of candor or disclosure to the stockholders of Parent under applicable law. For purposes of this Agreement, such recommendation of the Board of Directors shall be deemed to have been modified in a manner adverse to the Company if such recommendation shall no longer be unanimous.

(e) No amendment or supplement to the Joint Proxy Statement or the Registration Statement will be made by Parent or the Company without the approval of the other party (such approval not to be unreasonably withheld or delayed). Each of Parent and the Company will advise the other, promptly after it

receives notice thereof, of the time at which the Registration Statement has become effective or any supplement or amendment has been filed, of the issuance of any stop order, of the suspension of the qualification of the Parent Common Shares issuable in connection with the Merger for offering or sale in any jurisdiction, or of any request by the SEC for amendment of the Joint Proxy Statement or the Registration Statement or comments thereon and responses thereto or requests by the SEC for additional information.

(f) The information supplied by Parent for inclusion in the Registration Statement and the Joint Proxy Statement shall not, at (i) the time the Registration Statement is declared effective, (ii) the time the Joint Proxy Statement (or any amendment thereof or supplement thereto) is first mailed to the stockholders of the Company, (iii) the time the Joint Proxy Statement (or any amendment thereof or supplement thereto) is first mailed to the stockholders of Parent, (iv) the time of the Company Stockholders’ Meeting, (v) the time of the Parent Stockholders’ Meeting and (vi) the Effective Time, contain any untrue statement of a material fact or fail to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading.

If, at any time prior to the Effective Time, any event or circumstance relating to the Company or any Company Subsidiary, or their respective officers or directors, that should be set forth in an amendment or a supplement to the Registration Statement or Joint Proxy Statement should be discovered by the Company, the Company shall promptly inform Parent.

(b) The parties shall comply with, and shall cause their respective Representatives to comply with, all of their obligations under the Non-Disclosure Agreement dated October 15, 2003 (the “Non-Disclosure Agreement”), between the Company and Parent.

(d) Prior to the Company Stockholder Approval, but only after payment by the Company to Parent of the Termination Fee as set forth in Section 8.05(b), the Company’s Board of Directors may terminate this Agreement and recommend a Superior Proposal, if it so chooses, provided that that Company shall have provided Parent two business days’ prior written notice that the Company is prepared to accept a Superior Proposal, specifying the terms and conditions of such Superior Proposal in reasonable detail and identifying the person or entity making such Superior Proposal and provided further the Company shall not have breached (other than inadvertent immaterial breaches) any of the provisions of this Section 6.05.

(e) Nothing contained in this Agreement shall prohibit the Company or its Board of Directors from taking and disclosing to its stockholders a position contemplated by Rules 14d-9 and 14e-2(a) promulgated under the Exchange Act.

(a) The Certificate of Incorporation and Bylaws of the Surviving Corporation shall contain the same provisions with respect to indemnification, advancement and director exculpation set forth in the Certificate of Incorporation and Bylaws of the Company on the date of this Agreement, which provisions shall not be amended, repealed or otherwise modified for a period of six years from the Effective Time in any manner

that would affect adversely the rights thereunder of persons who at any time prior to the Effective Time were entitled to indemnification, advancement or exculpation under the Certificate of Incorporation or Bylaws of the Company in respect of actions or omissions occurring at or prior to the Effective Time (including, without limitation, the transactions contemplated by this Agreement), unless such modification is required by Law.

(b) After the Effective Time, Parent and the Surviving Corporation shall, to the fullest extent permitted under applicable Law and as required by any indemnification agreements of the Company (as each is in effect on the date hereof), indemnify and hold harmless, each present and former director or officer of the Company and each Company Subsidiary and each such person that served at the request of the Company or any Company Subsidiary as a director, officer, trustee, partner, fiduciary, employee or agent of another corporation, partnership, joint venture, trust, pension or other employee benefit plan or enterprise (collectively, the “Indemnified Parties”) against all costs and expenses (including reasonable attorneys’ fees), judgments, fines, losses, claims, damages, liabilities and settlement amounts paid in connection with any claim, action, suit, proceeding or investigation (whether arising before or after the Effective Time), whether civil, administrative or investigative, arising out of or pertaining to any action or omission in their capacities as officers or directors, in each case occurring before the Effective Time (including the transactions contemplated by this Agreement). Nothing contained herein shall make Parent, Merger Sub, the Company or the Surviving Corporation an insurer, a co-insurer or an excess insurer in respect of any insurance policies that may provide coverage for any of the foregoing, nor shall this Section 6.06 relieve the obligations of any insurer in respect thereto. Without limiting the foregoing, in the event of any such claim, action, suit, proceeding or investigation, (i) Parent and the Surviving Corporation shall advance or pay the reasonable fees and expenses of counsel selected by any Indemnified Party, which counsel shall be reasonably satisfactory to Parent and the Surviving Corporation, promptly after statements therefor are received (unless the Surviving Corporation shall elect to defend such action) and (ii) Parent and the Surviving Corporation shall cooperate in the defense of any such matter; provided, however, that neither Parent nor the Surviving Corporation shall be liable for any settlement effected without its written consent (which consent shall not be unreasonably withheld or delayed).

(c) For a period of six years after the Effective Time, Parent shall cause to be maintained in effect the current directors’ and officers’ liability insurance policies maintained by the Company with respect to claims arising from facts or events that occurred prior to the Effective Time (including with respect to the transactions contemplated by this Agreement); provided, however, that in no event shall Parent be required to expend pursuant to this Section 6.06(c) more than an amount per year equal to 200% of current annual premiums paid by the Company for such insurance; provided further that if the existing directors’ and officers’ liability insurance policy expires, is terminated or cancelled during such six-year period, Parent shall cause to be obtained as much directors’ and officers’ liability insurance as can be obtained for the remainder of such period for a premium not in excess (on an annualized basis) of 200% of the current annual premium paid by the Company for such insurance.

(d) This Section 6.06 is intended to be for the benefit of, and shall be enforceable by, the Indemnified Parties and their heirs and personal representatives and shall be binding on the Surviving Corporation and its successors and assigns. In the event the Company or the Surviving Corporation or any of their respective successors or assigns (i) consolidates with or merges into any other person and shall not be the continuing or surviving corporation or entity in such consolidation or merger or (ii) transfers all or substantially all of its properties and assets to any person, then, and in each case, proper provision shall be made so that the successors and assigns of the Company or the Surviving Corporation, as the case may be, honor the indemnification obligations set forth in this Section 6.06.

SECTION 6.08 Affiliates Agreements. As promptly as practicable, the Company shall deliver to Parent a letter identifying all persons who are, at the time this Agreement is submitted for adoption by the stockholders of the Company, an “affiliate” of the Company for purposes of Rule 145 under the Securities Act. The Company shall use its commercially reasonable efforts to deliver or cause to be delivered to Parent, prior to the Effective Time, an affiliate agreement in the form attached hereto as Exhibit C (an ”Affiliate Agreement”), executed by each of the affiliates of the Company identified in the foregoing letter and any person who shall, to the knowledge of the Company, have become an affiliate of the Company subsequent to the delivery of such list. The foregoing notwithstanding, Parent shall be entitled to place legends as specified in the Affiliate Agreement on the certificates evidencing any of the Parent Common Shares to be received by any such affiliate, and to issue stop transfer instructions to the transfer agent for Parent Common Shares, consistent with the term of the Affiliate Agreement, regardless of whether such affiliate has executed the Affiliate Agreement.

(a) Upon the terms and subject to the conditions hereof, each of the parties hereto shall use its reasonable best efforts to (i) take, or cause to be taken, all appropriate action and do, or cause to be done, all things necessary, proper or advisable under applicable Law or otherwise to consummate and make effective the Merger and the other transactions contemplated by this Agreement, (ii) obtain from Governmental Entities any consents, licenses, permits, waivers, approvals, authorizations or orders required to be obtained or made by Parent or the Company or any of their subsidiaries in connection with the authorization, execution and delivery of this Agreement and the consummation of the Merger and the other transactions contemplated by this Agreement and (iii) make all necessary filings, and thereafter make any other submissions, with respect to this Agreement, the Merger and the other transactions contemplated by this Agreement that are required under (A) the Exchange Act and the Securities Act and any other applicable federal or state securities laws, (B) the HSR Act and foreign antitrust regulations, if any, applicable to the Merger and the other transactions contemplated hereunder and (C) any other applicable Law. The parties hereto shall cooperate with each other in connection with the making of all such filings.

(b) Parent and the Company shall, as soon as practicable after the date of this Agreement, file notifications under the HSR Act and make any required antitrust filings in foreign jurisdictions and shall respond as promptly as practicable to all inquiries or requests received from the Federal Trade Commission or the Antitrust Division of the Department of Justice for additional information or documentation and shall respond as promptly as practicable to all inquiries and requests received from any state attorney general or other Governmental Entity in connection with antitrust matters. The parties shall cooperate with each other in connection with the making of all such filings or responses. Notwithstanding anything to the contrary in this Section 6.09, Parent shall not be required to agree to (i) the divestiture (including, without limitation, through a licensing arrangement) by Parent, any Parent Subsidiary, the Company or any Company Subsidiary of any of their respective businesses, product lines or assets, or (ii) the imposition of any material limitation on the ability of any of them to conduct their business or to own or exercise control of such assets, properties and stock.

SECTION 6.12 Reasonable Best Efforts and Further Assurances. Subject to the terms and conditions hereof, each of the parties to this Agreement shall use reasonable best efforts to effect the transactions contemplated hereby and to fulfill and cause to be fulfilled the conditions to the Merger under this Agreement. Subject to the terms and conditions hereof, each party hereto, at the reasonable request of another party hereto, shall execute and deliver such other instruments and do and perform such other acts and things as may be necessary or desirable for effecting completely the consummation of this Agreement and the transactions contemplated hereby.

(a) All employees of the Company shall continue in their existing benefit plans until such time as, in Parent’s sole discretion, an orderly transition can be accomplished to employee benefit plans and programs (other than the sabbatical program) maintained by Parent for its and its affiliates’ employees. The employees of the Company shall be eligible to participate in the employee benefit plans of Parent on terms and conditions no less favorable than those offered to similarly situated employees of Parent. Parent will cause such employee benefit plans to take into account, for purposes of eligibility and vesting, and, with respect to severance and vacation benefits, benefit accrual thereunder, services by employees of the Company and the Company Subsidiaries as if such services were with Parent to the same extent that such service was credited under a comparable plan of the Company. Any restriction on coverage for pre-existing conditions or requirement for evidence of insurability under the employee benefit plans of Parent shall be waived, and employees of the Company and the Company Subsidiaries shall receive credit under the employee benefit plans of Parent for co-payments and payments under a deductible limit made by them and for out-of-pocket maximums applicable to them during the applicable plan year of the Company Benefit Plan in accordance with the corresponding employee benefit plans of Parent. Parent shall, and shall cause the Surviving Corporation to, honor all compensation and employee benefit plan obligations under the Company Benefit Plans and all employment or severance agreements entered into by the Company or adopted by the Board of Directors of the Company, except to the extent that the Company Benefit Plans provide that they are terminable by the Company; provided that, with respect to severance benefits, employees of the Company shall, until March 31, 2005, remain eligible for severance benefits for non-performance-related terminations that are no less favorable than the severance benefits to which such employees were entitled under the Company’s severance policy; provided, further, Parent shall, and shall cause the Surviving Corporation to, pay, on June 30, 2004 (or if the Effective Time shall not have occurred by such date, Parent shall permit the Company to pay), to employees of the Company bonuses accrued for the six months ended June 30, 2004 pursuant to the Company’s bonus programs for fiscal year 2004, as in effect on the date of this Agreement (provided that the amount of bonuses paid pursuant to this proviso shall not exceed $3,000,000 in the aggregate).

(b) Parent agrees that, from and after the first enrollment date under the Parent Purchase Plan coinciding with or following the Effective Time, the employees of Company or any Company Subsidiary that become employees of Parent or any Parent Subsidiary may participate in the Parent Purchase Plan, and that service with the Company or any Company Subsidiary shall be treated as service with Parent for determining eligibility of the Company’s employees under the Parent Purchase Plan.

SECTION 6.14 Employment Agreements. Simultaneously with the execution of this Agreement, the employees of the Company identified in Section 6.14 of the Company Disclosure Letter shall enter into employment agreements (the “Employment Agreements”) with Parent.

SECTION 6.16 Rights Plan. Prior to the earlier of the termination of this Agreement pursuant to Section 8.01 hereof or the Effective Time, the Company and its Board of Directors shall not amend or modify or take any other action with regard to the Rights Plan in any manner or take any other action so as to (a) render the Rights Plan inapplicable to any transaction(s) other than the Merger and other transactions contemplated by this Agreement and the Voting Agreements, (b) permit any person or group who would otherwise be an Acquiring Person (as defined in the Rights Plan) not to be an Acquiring Person, (c) provide that a Distribution Date or Stock Acquisition Date or Triggering Event (as such terms are defined in the Rights Plan) or similar event does not occur as promptly as practicable by reason of the execution of any agreement or transaction other than this Agreement and the Voting Agreements and the Merger and the agreements and transactions contemplated hereby and thereby, or (d) except as specifically contemplated by this Agreement, otherwise affect the rights of holders of Rights (as defined in the Rights Plan). The Company and its Board of Directors shall take all action to ensure that the Rights Plan is and, through the Effective Time, will be inapplicable to Parent and Merger Sub, this Agreement, the Merger, the Voting Agreements and the transactions contemplated hereby and thereby. Pursuant to the amendment of the Rights Plan contemplated in Section 3.27 hereof, the rights under the Rights Plan shall expire immediately prior to the Effective Time.

SECTION 6.17 Parent Board of Directors. Parent shall take all requisite action to appoint David H. McCormick to the Parent Board of Directors (the “Parent Board”) as a member of Class I and Karl E. Newkirk to the Parent Board as a member of Class II, each as of the Effective Time, provided that if either David H. McCormick or Karl E. Newkirk is unable or unwilling to serve on the Parent Board at the Effective Time, Parent shall instead take all requisite action to appoint such other person or persons as the Company may designate and who is reasonably acceptable to the Board of Directors of Parent consistent with its fiduciary duties.

SECTION 6.18 Parent Officers. Parent shall take all requisite action to appoint David H. McCormick as President of Parent as of the Effective Time.

SECTION 6.19 Section 16 Matters. Provided that the Company delivers to Parent the Section 16 Information (as defined below) in a timely fashion, the Parent Board, or an appropriate committee of non-employee directors thereof, shall adopt resolutions prior to the consummation of the Merger providing that the receipt by the Company Insiders (as defined below) of the Parent Common Shares upon conversion of the Company Common Stock, and of options for Parent Common Shares upon conversion of the Company Stock Options, in each case pursuant to the transactions contemplated hereby and to the extent such securities are listed in the Section 16 Information, are intended to be exempt from liability pursuant to Section 16(b) under the Exchange Act. Such resolutions shall comply with the approval conditions of Rule 16b-3 under the Exchange Act for purposes of such Section 16(b) exemption, including, but not limited to, specifying the name of the Company Insiders, the number of securities to be acquired or disposed of for each such person, the material terms of any derivative securities, and that the approval is intended to make the receipt of such securities exempt pursuant to Rule 16b-3(d). “Section 16 Information” shall mean information regarding the Company Insiders, the number of shares of the Company Common Stock held by each such Company Insider and expected to be exchanged for Parent Common Shares in connection with the Merger, and the number and description of the Company Stock Options held by each such Company Insider and expected to be converted into options for Parent Common Shares in connection with the Merger. “Company Insiders” shall mean those officers and directors of the Company who will be subject to the reporting requirement of Section 16(b) of the Exchange Act with respect to Parent and who are listed in the Section 16 Information.

(a) This Agreement is intended to constitute a “plan of reorganization” within the meaning of section 1.368-2(g) of the income tax regulations promulgated under the Code. From and after the date of this Agreement, each party hereto shall use its reasonable best efforts to cause the Merger to qualify, and will not knowingly take any action, cause any action to be taken, fail to take any action or cause any action to fail to be taken which action or failure to act would reasonably be expected to prevent the Merger from

qualifying as a reorganization under the provisions of section 368(a) of the Code or that would reasonably be expected to prevent the Alternative Double Merger from qualifying for tax-free treatment (either as a reorganization as defined in Section 368(a) of the Code, a transfer to a corporation controlled by the transferor within the meaning of Section 351(a) of the Code, or a combination of both).

(b) As of the date of this Agreement, the Company does not know of any reason why it would not be able to deliver to Gunderson Dettmer or Morgan, Lewis & Bockius LLP (“Morgan Lewis”), at the date of the legal opinions referred to below, certificates substantially in compliance with IRS published advance ruling guidelines, with customary exceptions and modifications thereto, to enable such firms to deliver the legal opinions contemplated by Sections 7.02(d) and 7.03(c), and the Company hereby agrees to deliver such certificates effective as of the date of such opinions.

(c) As of the date of this Agreement, Parent and Merger Sub do not know of any reason why they would not be able to deliver to Gunderson Dettmer or Morgan Lewis, at the date of the legal opinions referred to below, certificates substantially in compliance with IRS published advance ruling guidelines, with customary exceptions and modifications thereto, to enable such firms to deliver the legal opinions contemplated by Sections 7.02(d) and 7.03(c), and Parent hereby agrees to deliver such certificates effective as of the date of such opinions.

SECTION 6.21 Alternative Double Merger. The parties agree that each will make a good faith attempt to obtain the tax opinions referred to in Section 6.20. If for any reason the tax opinion conditions in Sections 7.02(d) and 7.03(c) are not satisfied on or prior to the Closing, the parties shall, subject to the receipt of tax opinions as described below, implement an Alternative Double Merger Transaction (as defined below) on the terms and conditions contained in this Agreement (preserving the economic and financial terms of this Agreement) with such modifications to such terms and conditions as are required to implement such structure. An “Alternative Double Merger Transaction” means a transaction whereby the following shall occur: (i) Parent will cause Merger Sub (or another entity formed by Parent solely to effect the Alternative Double Merger Transaction) (“Holding Company”) to form two wholly-owned subsidiaries under the DGCL (“Parent Merger Subsidiary” and “Company Merger Subsidiary”, respectively); (ii) Parent and the Company will cause Parent Merger Subsidiary and Company Merger Subsidiary and, if applicable, Holding Company, to become parties to this Agreement and to execute and deliver all documents required by the DGCL to authorize and adopt this Agreement; (iii) in lieu of shares of Parent Common Shares, an equal number of shares of common stock of Holding Company, together with associated rights similar in all material respects to the rights of the Parent Common Shares (“Holding Company Common Stock”) shall be issued as the stock portion of the Per Share Merger Consideration, and appropriate conforming changes shall be made to this Agreement; (iv) Parent Merger Subsidiary shall be merged with and into Parent in accordance with the DGCL, whereupon the separate existence of Parent Merger Subsidiary shall cease, stockholders of Parent shall receive one share of Holding Company Common Stock in exchange for each share of Parent Common Shares and Parent shall be the surviving corporation and a wholly owned subsidiary of Holding Company; and (v) Company Merger Subsidiary shall be merged with and into the Company in accordance with the DGCL, whereupon the separate existence of Company Merger Subsidiary shall cease, and the Company shall be the surviving corporation and a wholly owned subsidiary of Holding Company. Each of the foregoing elements of an Alternative Double Merger Transaction may be undertaken at such times as mutually agreed by the Company and Parent with the advice of counsel. It is intended that (i) the receipt of Holding Company Common Stock by the holders of Parent Common Shares in exchange for their shares of Parent Common Shares will be treated as having occurred pursuant to either a reorganization as defined in Section 368(a) of the Code and/or a transaction governed by Section 351(a) of the Code, and Parent will use its commercially reasonable efforts to obtain the opinion of its counsel to that effect, and (ii) the receipt of Holding Company Common Stock and cash by the holders of the Company Common Stock in exchange for their shares of Company Common Stock will be treated as having occurred pursuant to a transaction governed by Section 351(a) and, if applicable, Section 351(b) of the Code, and the Company will use its commercially reasonable efforts to obtain the opinion of its counsel to that effect. In the event that counsel for the Company is unable to render the opinion referred to above, the opinion condition of this Section 6.21 shall be deemed satisfied if counsel for Parent renders such opinion to the Company.

(e) Antitrust Waiting Periods. Any waiting period (and any extension thereof) applicable to the consummation of the Merger under the HSR Act shall have expired or been terminated and any waiting period (and any extension thereof) applicable to the consummation of the Merger under any foreign antitrust Law (or any approval thereunder) shall have expired or been terminated.
