The date on which the Closing occurs is referred to in this Agreement as the “Closing Date.” As used in this Agreement, the term “Business Day” shall mean any day other than a Saturday, Sunday or a day on which banks in New York City are authorized or obligated by Law or executive order to close.

SECTION 1.3 Effective Time. Subject to the provisions of this Agreement, as promptly as practicable on the Closing Date, the parties shall file with the Secretary of State of the State of Delaware a certificate of merger (the “Certificate of Merger”) executed and acknowledged by the parties in accordance with the relevant provisions of the DGCL and, as promptly as practicable on or after the Closing Date, shall make all other filings or recordings required under the DGCL or applicable Italian Law. The Merger shall become effective upon the filing of the Certificate of Merger with the Secretary of State of the State of Delaware, or at such later date and time as Parent and the Company shall agree and shall specify in the Certificate of Merger (the date and time that the Merger becomes effective being the “Effective Time”).

SECTION 1.4 Effects of The Merger. At and after the Effective Time, the Merger shall have the effects set forth in this Agreement and the applicable provisions of the DGCL.

SECTION 1.5 Certificate of Incorporation And Bylaws.

SECTION 1.6 Directors. The directors of Sub immediately prior to the Effective Time shall, from and after the Effective Time, be the directors of the Surviving Corporation, until the earlier of their resignation or removal or until their respective successors are duly elected and qualified, as the case may be.

SECTION 1.7 Officers. The officers of Sub immediately prior to the Effective Time, from and after the Effective Time, shall be the officers of the Surviving Corporation, until the earlier of their resignation or removal or until their respective successors are duly elected and qualified, as the case may be.

ARTICLE 2.

Effect of the Merger on the Capital; Exchange of Certificates

SECTION 2.1 Effect on Capital Stock. At the Effective Time, by virtue of the Merger and without any action on the part of the holders of any shares of capital stock of the Company or any shares of capital stock of Parent or Sub:

(a) Common Stock of Sub. Each issued and outstanding share of common stock, par value $0.01 per share, of Sub shall be converted into and become one validly issued,

fully paid and non-assessable share of identical common stock, par value $0.01 per share, of the Surviving Corporation and shall constitute the only outstanding shares of capital stock of the Surviving Corporation.

(b) Cancellation of Treasury Stock and Parent-Owned Stock. Each share of the Company’s common stock, par value $0.001 per share (“Company Common Stock”) that is directly owned by the Company, Parent, Sub, or any direct or indirect wholly-owned subsidiary of the Company or Parent immediately prior to the Effective Time shall automatically be canceled and shall cease to exist, and no consideration shall be delivered in exchange therefor.

(c) Conversion of Company Common Stock. Each share of Company Common Stock, including the associated right (the “Rights”) to purchase one-hundredth of a share of Series A Junior Participating Preferred Stock, par value $0.001 per share (“Series A Preferred Stock”), of the Company or in certain circumstances Company Common Stock pursuant to the Shareholders Rights Agreement dated as of June 28, 2001, as amended, by and between the Company and American Stock Transfer & Trust Company, as Rights Agent (the “Rights Agreement”), issued and outstanding immediately prior to the Effective Time (other than shares to be canceled in accordance with Section 2.1(b) of this Agreement and the Appraisal Shares (as defined in Section 2.1(d) of this Agreement) shall be converted into the right to receive $29.10 in cash (as such amount may be adjusted pursuant to Section 2.2(h)), without interest (the “Merger Consideration”). At the Effective Time, all such shares of Company Common Stock (and the associated Rights) shall no longer be outstanding and shall automatically be canceled and shall cease to exist, and any such share of Company Common Stock (and the associated Rights) shall cease to have any rights with respect thereto, except the right to receive the Merger Consideration. The right of any holder of a Certificate to receive the Merger Consideration shall be subject to and reduced by the amount of any withholding and/or deduction that is required under applicable Tax Law in accordance with Section 2.2(i) of this Agreement. The Merger Consideration shall be paid in the manner set forth in Section 2.2.

(d) Appraisal Rights. Notwithstanding anything in this Agreement to the contrary, shares (the “Appraisal Shares”) of Company Common Stock (and the associated Rights) issued and outstanding immediately prior to the Effective Time that are held by any holder who is entitled to demand and properly demands appraisal of such Appraisal Shares pursuant to, and who complies in all respects with, the provisions of Section 262 of the DGCL (“Section 262”) shall not be converted into the right to receive the Merger Consideration as provided in Section 2.1(c) of this Agreement, but instead such holder shall be entitled to payment of the fair value of such Appraisal Shares in accordance with the provisions of Section 262. At the Effective Time, all Appraisal Shares shall no longer be outstanding, shall automatically be canceled and shall cease to exist, and each holder of Appraisal Shares shall cease to have any rights with respect thereto, except the right to receive the fair value of such Appraisal Shares in accordance with the provisions of Section 262. Notwithstanding the foregoing, if any such holder shall fail to perfect or otherwise shall waive, withdraw or lose the right to appraisal under Section 262, or a court of competent jurisdiction shall determine that such holder is not entitled to the relief provided by Section 262, then the right of such holder to be paid the fair value of such holder’s Appraisal Shares under Section 262 shall cease and such Appraisal Shares shall be deemed to have been converted at the Effective Time into, and shall have become, the right to receive the Merger Consideration as provided in Section 2.1(c) of this Agreement. The

Company shall serve prompt notice to Parent of any demands for appraisal of any shares of Company Common Stock, and Parent shall have the right to participate in and direct all negotiations and proceedings with respect to such demands. Prior to the Effective Time, the Company shall not, without the prior written consent of Parent, voluntarily make any payment with respect to, or settle or offer to settle, any such demands, or agree to do any of the foregoing.

(e) Stock Options. At the Effective Time, each outstanding option to purchase shares of Company Common Stock (a “Company Option”) under any employee stock option or compensation plan or arrangement of the Company, including the 1995 Stock Option Plan, the 1997 Equity Incentive Plan, the 2001 Stock Option Plan, the 2002 Stock Option Plan and the 2003 New-Hire Stock Option Plan (collectively, the “Employee Benefit Plans”), whether or not exercisable or vested, shall by virtue of the Merger and without any action on the part of any holder of any Company Option be cancelled and the holder thereof will receive within 10 Business Days of the Effective Time a cash payment with respect thereto equal to the product of (a) the excess, if any, of the Merger Consideration over the exercise price per share of such Company Option, and (b) the number of shares of Company Common Stock issuable upon exercise of such Company Option (the “Option Cash Payment”). All amounts payable pursuant to this Section 2.1(e) of this Agreement shall be subject to and reduced by the amount of any withholding and/or deduction that is required under applicable Tax Law in accordance with Section 2.3 of this Agreement. As of the Effective Time, all Company Options shall no longer be outstanding and shall automatically cease to exist, and each holder of a Company Option shall cease to have any rights with respect thereto, except the right to receive the Option Cash Payment. The Company shall use commercially reasonable efforts such that, upon the Effective Time, each Company Option is treated in accordance with this Section 2.1(e) of this Agreement.

(f) Employee Stock Purchase Plan. The Company shall take any and all actions with respect to the Company’s Employee Stock Purchase Plan (the “ESPP”) as are necessary to provide that the ESPP shall terminate, effective as of the Effective Time, and each Option (as defined in the ESPP) outstanding for the Offering Period (as defined in the ESPP) under the ESPP that terminates at the Effective Time shall be cancelled and each participant in the ESPP for that Offering Period shall be entitled to receive, within 10 Business Days of the Effective Time, in lieu of any other amounts otherwise payable to such participant under the ESPP with respect to such Option, an amount in cash equal to (a) the Merger Consideration multiplied by (b) the number of whole and fractional shares of Company Common Stock that would have been issuable upon exercise of such Option had it been exercised at the Effective Time and the participant purchased the maximum number of shares subject thereto using the full amount of his or her Contributions (as defined in the ESPP) to the ESPP for that Offering Period. All amounts payable pursuant to this Section 2.1(f) of this Agreement shall be subject to and reduced by the amount of any withholding that is required under applicable Tax Law, in accordance with Section 2.2(i) of this Agreement.

(g) Warrants. At the Effective Time, each warrant to purchase Company Common Stock or capital stock convertible into Company Common Stock (the “Warrants”) outstanding immediately prior to the Effective Time shall be canceled in exchange for a lump sum cash payment equal to (i) the product of (A) the number of shares of Company Common Stock subject to such Warrant and (B) the Merger Consideration, minus (ii) the per share exercise price of such Warrant (provided that if such calculation results in a negative number, the

lump sum cash payment shall be deemed to be $0) (the “Warrant Cash Payment”). Such payment shall be made within ten Business Days of the Effective Time. All amounts payable pursuant to this Section 2.1(g) of this Agreement shall be subject to and reduced by the amount of any withholding and/or deduction that is required under applicable Tax Law in accordance with Section 2.2(i) of this Agreement.

SECTION 2.2 Exchange of Shares.

(a) Paying Agent. Prior to the Effective Time, Parent shall appoint a bank or trust company reasonably acceptable to the Company to act as paying agent (the “Paying Agent”) for the payment of the Merger Consideration. At the Effective Time, Parent shall deposit, or cause the Surviving Corporation to deposit, with the Paying Agent, for the benefit of the holders of Certificates, cash in an amount sufficient to pay the aggregate Merger Consideration required to be paid pursuant to Section 2.1(c) of this Agreement (such cash being hereinafter referred to as the “Exchange Fund”).

(b) Exchange Procedures. As soon as reasonably practicable after the Effective Time, Parent shall cause the Paying Agent to mail to each holder of record of a share of Company Common Stock (i) a form of letter of transmittal (which shall specify when delivery of shares of Company Common Stock shall be effected, and, with respect to certificates representing shares of Company Common Stock immediately prior to the Effective Time (“Certificates”), that the risk of loss and title to Certificates shall pass only upon proper delivery of the Certificates to the Paying Agent and which letter of transmittal shall be in customary form and have such other provisions as Parent may reasonably specify) and (ii) instructions for use in effecting the surrender of Certificates or the surrender of common stock held in book-entry form (including through book-entry positions with depository intermediaries participating in Monte Titoli S.p.A.) in exchange for the Merger Consideration. Each holder of record of a share of Company Common Stock shall, upon surrender to the Paying Agent of a Certificate or compliance with the instructions for book-entry tender of such share, together with submission of a letter of transmittal, duly executed, and such other documents as may reasonably be required by the Paying Agent, be entitled to receive in exchange therefor the amount of cash which the number of shares of Company Common Stock (and the associated Rights) previously represented by such Certificate or held in book-entry form shall have been converted into the right to receive pursuant to Section 2.1(c) of this Agreement, and the Certificate so surrendered shall forthwith be canceled. In the event of a transfer of ownership of Company Common Stock (and the associated Rights) which is not registered in the transfer records of the Company, payment of the Merger Consideration may be made to a person other than the person in whose name the Certificate so surrendered is registered if such Certificate shall be properly endorsed or otherwise be in proper form for transfer and the person requesting such payment shall pay any transfer or other Taxes required by reason of the payment of the Merger Consideration to a person other than the registered holder of such Certificate or establish to the reasonable satisfaction of Parent that such Tax has been paid or is not applicable. Until surrendered as contemplated by this Section 2.2(b) of this Agreement, each Certificate shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender the Merger Consideration which the holder thereof has the right to receive in respect of such Certificate pursuant to the provisions of this Article II. No interest shall be paid or will accrue on any cash payable to holders of shares of Company Common Stock pursuant to the provisions of this Article II.

(c) No Further Ownership Rights in Company Common Stock. All cash paid upon the surrender of shares of Company Common Stock in accordance with the terms of this Article II shall be deemed to have been paid in full satisfaction of all rights pertaining to such shares of Company Common Stock (and the associated Rights). At the close of business on the day on which the Effective Time occurs, the stock transfer books of the Company shall be closed, and there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of the shares of Company Common Stock (and the associated Rights) that were outstanding immediately prior to the Effective Time. If, after the Effective Time, any Certificate is presented to the Surviving Corporation for transfer, it shall be canceled against delivery of cash to the holder thereof as provided in this Article II.

(d) Termination of the Exchange Fund. Any portion of the Exchange Fund which remains undistributed to the holders of the Certificates for six months after the Effective Time shall be delivered to Parent, upon demand, and any holders of the Certificates who have not theretofore complied with this Article II shall thereafter look only to Parent for, and Parent shall remain liable for, payment of their claim for the Merger Consideration.

(e) No Liability. None of Parent, Sub, the Company, the Surviving Corporation or the Paying Agent shall be liable to any person in respect of any cash from the Exchange Fund properly delivered to a public official pursuant to any applicable abandoned property, escheat or similar law. If any Certificate shall not have been surrendered prior to two years after the Effective Time (or immediately prior to such earlier date on which any Merger Consideration would otherwise escheat to or become the property of any Governmental Entity (as defined below)) any such Merger Consideration shall, to the extent permitted by applicable Law, become the property of Parent, free and clear of all claims or interest of any person previously entitled thereto. “Governmental Entity” is defined in this Agreement as any Federal, state, local or foreign government, any court, administrative, regulatory or other governmental agency, commission or authority or any non-governmental self-regulatory agency, commission or authority, including domestic or foreign stock exchanges and securities regulatory bodies.

(f) Investment of Exchange Fund. The Paying Agent shall invest the cash in the Exchange Fund as directed by Parent on a daily basis. Any interest and other income resulting from such investments shall be paid to Parent.

(g) Lost 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 reasonably required by Parent, the posting by such person of a bond in such reasonable amount as Parent may direct as indemnity against any claim that may be made against it with respect to such Certificate, the Paying Agent shall deliver in exchange for such lost, stolen or destroyed Certificate the applicable Merger Consideration with respect thereto.

(h) Adjustments. If at any time during the period between the date of this Agreement and the Effective Time, a change in the outstanding shares of capital stock of the Company shall occur by reason of any reclassification, recapitalization, stock split or combination, exchange or readjustment of shares, the Merger Consideration shall be adjusted appropriately.

(i) Withholding Rights. Parent, the Surviving Corporation or the Paying Agent shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any holder of shares of Company Common Stock (and the associated Rights), Company Options or Warrants, as applicable, such amounts as Parent, the Surviving Corporation or the Paying Agent, as applicable, is required to deduct and withhold with respect to the making of such payment under the Internal Revenue Code of 1986, as amended (the “Code”), or any provision of state, local or foreign Tax Law. To the extent that amounts are so withheld and paid over to the appropriate Taxing Authority by Parent, the Surviving Corporation or the Paying Agent, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the shares of Company Common Stock (and the associated Rights), Company Options or Warrants, as applicable, in respect of which such deduction and withholding was made by such party.

ARTICLE 3.

The Company and each of its Subsidiaries is qualified to do business and is in good standing as a foreign corporation in each jurisdiction where the ownership or operation of its properties and assets or conduct of its business requires such qualification, except for such failures to be so qualified or in good standing (with respect to such jurisdictions that recognize the concept of good standing) that would not be reasonably expected, either individually or in the aggregate, to have a Company Material Adverse Effect.

No shares of Company Preferred Stock are issued or outstanding. Each of the outstanding shares of capital stock or other securities of the Company is, and each share of Company Common Stock which may be issued in connection with any Company Options or Warrants will be, duly authorized, validly issued, fully paid and non-assessable. Each of the outstanding shares of capital stock or other securities of each of the Company’s Subsidiaries is duly authorized, validly issued, fully paid and non-assessable and is owned by the Company or a direct or indirect wholly-owned Subsidiary of the Company, free and clear of any lien, pledge, claim, option, charge, security interest, limitation, encumbrance and restriction of any kind (including any restriction on the right to vote, sell or otherwise dispose of such capital stock of other ownership interests). Other than with respect to the Subsidiaries listed on Section 3.1(c) of the Company Disclosure Schedule, the Company does not directly or indirectly own any securities or other beneficial ownership interests in any other entity (including through joint ventures or partnership arrangements), or have any investment in any other person. Other than as specified in Section 3.1(c) of the Company Disclosure Schedule, there are no preemptive or other outstanding rights, Company Options, Warrants, conversion rights, stock appreciation rights, redemption rights, repurchase rights, agreements, arrangements or commitments of any kind to which the Company or any of its Subsidiaries is a party, or by which the Company or any of its Subsidiaries are bound, obligating the Company or any of its Subsidiaries to issue, deliver or sell, or cause to be issued, delivered or sold, any shares of capital stock or other securities of the Company or any of its Subsidiaries or any securities or obligations convertible or exchangeable into or exercisable for, or giving any person a right to subscribe for or acquire, any securities of the Company or any of its Subsidiaries, and no securities or obligations evidencing such rights are authorized, issued or outstanding. Other than as specified in Section 3.1(c) of the Company Disclosure Schedule, neither the Company nor any of its Subsidiaries is a party to or aware of any voting or other stockholders agreement with respect to its securities or the securities of any of its Subsidiaries.

Each of Parent and Sub has all requisite corporate power to own and operate its properties and assets and to carry on its business as currently conducted, except where the failure to have such power and authority, individually or in the aggregate, would not reasonably be expected to have a Parent Material Adverse Effect. Each of Parent and Sub is qualified to do business and is in good standing as a foreign corporation in each jurisdiction where the ownership or operation of its properties and assets or conduct of its

Assuming due authorization, execution and delivery by the Company, this Agreement is a valid and legally binding agreement of Parent and Sub, enforceable against each of Parent and Sub in accordance with its terms, subject to applicable bankruptcy, insolvency, moratorium or other similar laws relating to creditors’ rights and general principles of equity. The Boards of Directors of Parent and Sub, and the Parent in its capacity as sole stockholder of Sub, have approved and adopted this Agreement and the Merger.

(d) No Conflicts. Neither the execution, delivery and performance of this Agreement by Parent and Sub and the consummation by Parent and Sub of the transactions contemplated hereby nor compliance by Parent and Sub with any of the provisions hereof will constitute or result in (A) a breach or violation of, or a default under the Organizational Documents of Parent, Sub or of any of Parent’s Subsidiaries, or (B) a breach or violation of, or a default under, the acceleration of any obligations, the loss of any right or benefit or the creation of a lien, pledge, security interest or other encumbrance on the assets of Parent, Sub or any of Parent’s Subsidiaries (with or without notice, lapse of time or both) pursuant to any contracts binding upon Parent, Sub or any of Parent’s Subsidiaries or any Law or governmental or non-governmental permit or license to which Parent, Sub or any of Parent’s Subsidiaries is subject, except, in the case of clause (B) above, for such breaches, violations, defaults, accelerations, creations or changes that would not, either individually or in the aggregate, be reasonably likely to have a Parent Material Adverse Effect.

The Company shall, shall cause its Subsidiaries, officers and directors to, and shall use commercially reasonable efforts to cause any employee, investment banker, financial advisor, attorney, accountant or other representative retained by it to, immediately cease and cause to be terminated any discussions or negotiations with any third party (other than Parent or Sub) conducted heretofore with respect to any Takeover Proposal. For purposes of this Agreement, “Takeover Proposal” means any bona fide inquiry, proposal, request or offer from any person relating to (i) any direct or indirect acquisition or purchase of a business or assets (a “Company Material Business”) that constitutes 10% or more of the net revenues, net income or the assets (including equity securities) of the Company and its Subsidiaries, taken as a whole, (ii) any direct or indirect acquisition or purchase of 10% or more of any class of voting securities of the Company or 10% or more of the voting power of any class of stock of any Subsidiary of the Company owning, operating or controlling a Company Material Business, (iii) any tender offer or exchange offer that if consummated would result in any person beneficially owning 10% or more of any class of voting securities of the Company or 10% or more of the voting power of any class of stock of any Subsidiary of the Company owning, operating or controlling a Company Material Business, (iv) any merger, consolidation, business combination, recapitalization, liquidation, dissolution or similar transaction involving the Company or any such Subsidiary of the Company owning, operating or controlling a Company Material Business, in each case other than the transactions contemplated by this Agreement, or (v) any sale, lease, exchange, transfer, license, acquisition, or disposition of more than 10% of the assets of the Company (including its subsidiaries, taken as a whole).

(b) Except as expressly permitted by this Section 4.2, neither the Board of Directors of the Company nor any committee thereof shall (i) withdraw or modify, or propose publicly to withdraw or modify, in a manner adverse to Parent, the approval or recommendation by such Board of Directors or such committee of this Agreement or the Merger, (ii) approve or recommend, or propose publicly to approve or recommend, any Takeover Proposal, or (iii) cause the Company to enter into any letter of intent, agreement in principle, acquisition agreement or other similar agreement (each, an “Acquisition Agreement”) related to any Takeover Proposal.

(ii) the Company shall have delivered to Parent written notice at least three Business Days prior to publicly effecting such Change of Recommendation or terminating this Agreement which shall state expressly (1) that the Company has received a Superior Proposal, (2) the material terms and conditions of the Superior Proposal and the identity of the Person or group making the Superior Proposal, and (3) that the Company intends to effect a Change of Recommendation or terminate this Agreement;

(iii) during the three Business Day period referenced in clause (ii) above, the Company negotiates with Parent in good faith with respect to adjustments to the terms and conditions of this Agreement that Parent may suggest during such period; and

(iv) during the three Business Day period referenced in clause (ii) above, such Board of Directors does not conclude in good faith that such Takeover Proposal (including any adjustments thereto during such three Business Day period) no longer constitutes a Superior Proposal.

For purposes of this Agreement, “Superior Proposal” means any written bona fide offer made by a third party to acquire, directly or indirectly, pursuant to a tender offer, exchange offer, merger, consolidation or other business combination, all or substantially all of the assets of the Company or all of the outstanding voting securities of the Company, on terms that the Board of Directors of the Company determines in good faith (after consultation with its financial advisor) to be more favorable (taking into account (i) all financial considerations, including relevant legal, financial, regulatory and other aspects of such Takeover Proposal and the Merger and the other transactions contemplated by this Agreement deemed relevant by the Board of Directors, (ii) the identity of the third party making such Takeover Proposal and (iii) the conditions and prospects for completion of such Takeover Proposal) to the Company’s stockholders than the Merger and the other transactions contemplated by this Agreement (taking into account all of the terms of any proposal by Parent to amend or modify the terms of the Merger and the other transactions contemplated by this Agreement).

(d) In addition to the obligations of the Company set forth in paragraphs (a) and (b) of this Section 4.2, the Company shall (i) as promptly as practicable advise Parent of any Takeover Proposal, the principal terms and conditions of any such Takeover Proposal (including any changes thereto) and the identity of the person making any such Takeover Proposal, (ii) provide Parent with (A) a copy of all written materials provided by or on behalf of such person in connection with the Takeover Proposal that describe or relate to the terms and conditions of such Takeover Proposal and (B) notice of the Company’s intention to enter into negotiations with any third party with respect to a Takeover Proposal, and (iii) contemporaneously with furnishing any nonpublic information with regard to the Company and its Subsidiaries to such third party, furnish such nonpublic information to Parent (to the extent such nonpublic information has not been previously so furnished). The Company shall keep Parent informed of the status and details (including providing notice to Parent promptly, and in any event within 24 hours, of any changes to any material term thereof) of any such Takeover Proposal. Contemporaneously with any termination by the Company of this Agreement pursuant to Section 7.1(b)(i) of this Agreement, the Company shall provide Parent with a written verification that it has complied with its obligations pursuant to this Section 4.2.

(e) Nothing contained in this Section 4.2 shall prohibit the Company from (i) taking and disclosing to its stockholders a position contemplated by Rule 14e-2(a) promulgated under the Exchange Act or from making any disclosure to the Company’s stockholders if, in the good faith judgment of the Board of Directors of the Company, after consultation with outside counsel, failure so to disclose would be inconsistent with its obligations under applicable Law, including the Board of Directors’ duty of candor to the stockholders of the Company or (ii) taking actions permitted by Section 4.1(d) of this Agreement.

(f) The parties hereto agree that irreparable damage would occur in the event that the provisions of this Section 4.2 were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed by the parties hereto that Parent shall be entitled to seek an immediate injunction or injunctions, without the necessity of proving the inadequacy of money damages as a remedy without the necessity of posting any bond or other security, to prevent breaches of the provisions of this Section 4.2 and to enforce specifically the terms and provisions hereof in any court of the United States or any state having jurisdiction, this being in addition to any other remedy to which Parent may be entitled at law or in equity.

respective Subsidiaries, shall give credit under each of their respective employee benefit plans, programs and arrangements in which Company Employees participate to Company Employees for all service prior to the Effective Time with the Company or Parent or their respective Subsidiaries, as applicable, or any predecessor employer (to the extent that such credit was given under similar plans, programs and arrangements by the Company or Parent or any of their respective Subsidiaries, as applicable) for all purposes for which such service was taken into account or recognized by the Company or Parent or their respective Subsidiaries, as applicable, but not (i) to the extent crediting such service would result in duplication of benefits, or (ii) for purposes of benefit accrual under any defined benefit pension plan.

SECTION 5.5 Indemnification; Advancement of Expenses; Exculpation and Insurance.

(a) Each of Parent and the Surviving Corporation agrees that, to the fullest extent permitted under applicable Law, all rights to indemnification, advancement of expenses and exculpation from liabilities for acts or omissions occurring at or prior to the Effective Time now existing in favor of the current or former directors, officers, employees or fiduciaries under benefit plans currently indemnified of the Company and its Subsidiaries, as provided in the Organizational Documents or other indemnification agreements in effect as of the date hereof shall survive the Merger and shall continue in full force and effect in accordance with their terms. In addition, from and after the Effective Time, directors, officers, employees and fiduciaries under benefit plans currently indemnified of the Company or its Subsidiaries who become directors, officers, employees or fiduciaries under benefit plans of the Surviving Corporation will be entitled to the indemnity rights and protections afforded to directors, officers, employees and fiduciaries under benefit plans of the Surviving Corporation.

(b) For six years after the Effective Time, Parent shall cause the Surviving Corporation to maintain in effect the directors’ and officers’ liability (and fiduciary) insurance policies currently maintained by the Company covering acts or omissions occurring on or prior to the Effective Time with respect to those persons who are currently covered by the Company’s directors’ and officers’ liability (and fiduciary) insurance policies on terms with respect to such coverage and in amounts no less favorable than those set forth in the relevant policy in effect on the date of this Agreement; provided, however, that in no event will Parent or the Surviving Corporation be required to expend annually in excess of 250% of the annual premium currently paid by the Company for such coverage (and to the extent the annual premium would exceed 250% of the annual premium currently paid by the Company for such coverage, the Surviving Corporation shall use all reasonable efforts to cause to be maintained the maximum amount of coverage as is available for such 250% of such annual premium) . In addition, the Company may satisfy its obligations under this Section 5.5(b) by purchasing a six-year “tail” prepaid policy on terms and conditions no less advantageous to the indemnified parties, or any other person entitled to the benefit of Sections 5.5(a) and (b) of this Agreement, as applicable, than the existing directors’ and officers’ liability (and fiduciary) insurance maintained by the Company, covering, without limitation, the transactions contemplated hereby. If such “tail” prepaid policy has been obtained by the Company prior to the Effective Time, the Parent shall, and shall cause the Surviving Corporation after the Effective Time, to maintain such policy in full force and effect, for its full term, and to continue to honor its respective obligations thereunder.

(c) From and after the Effective Time, each of Parent and the Surviving Corporation agrees that it will jointly and severally indemnify and hold harmless each present director and officer of the Company or any of its Subsidiaries, determined as of the date hereof, and any person who becomes such a director or officer between the date hereof and the Effective Time (collectively, the “Indemnified Person”), against any costs or expenses (including reasonable attorneys’ fees), judgments, fines, losses, claims, damages or liabilities (collectively, “Costs”) incurred in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, arising out of matters existing or occurring at or prior to the Effective Time, whether asserted or claimed prior to, at or after the Effective Time (including any matters arising in connection with the transactions contemplated by this Agreement), to the fullest extent permitted by applicable Law (and Parent and the Surviving Corporation shall also advance expenses as incurred to the fullest extent permitted under applicable law, provided that if required by applicable Law the person to whom expenses are advanced provides an undertaking to repay such advances if it is ultimately determined that such person is not entitled to indemnification); and provided, further, that any determination as to whether an Indemnified Person is entitled to indemnification or advancement of expenses hereunder pursuant to applicable Law shall be made by independent counsel jointly selected by the Surviving Corporation and such Indemnified Person. Parent or the Surviving Corporation will have the right to assume and control the defense of any action for which indemnification is sought hereunder or under the Company’s Organizational Documents or indemnification agreements. Parent and the Surviving Corporation shall be obligated to pay for only one firm or counsel for all indemnified parties in any jurisdiction, except to the extent there is, under applicable standards of professional conduct, a conflict on any significant issue between the positions of such indemnified party and any other indemnified party, in which case each indemnified party with a conflicting position on a significant issue shall be entitled to retain separate counsel mutually satisfactory to Parent and such indemnified party. The indemnified parties shall cooperate in the defense of any such matter. Parent shall not be liable for any settlement effected without its prior written consent (which consent shall not be unreasonably withheld).

(d) The obligations of Parent and the Surviving Corporation under this Section 5.5 shall not be terminated or modified by such parties in a manner so as to adversely affect any Indemnified Person, or any other person entitled to the benefit of Sections 5.5(a) and (b) of this Agreement, as the case may be, to whom this Section 5.5 applies without the consent of the affected Indemnified Person or such other person, as the case may be. If Parent or the Surviving Corporation or any of their respective successors or assigns (i) shall consolidate with or merge into any other corporation or entity and shall not be the continuing or surviving corporation or entity of such consolidation or merger or (ii) shall transfer all or substantially all of its properties and assets to any individual, corporation or other entity, then, and in each such case, proper provisions shall be made so that the successors and assigns of the Parent or the Surviving Corporation, as the case may be, shall assume all of the obligations set forth in this Section 5.5.

(e) The provisions of this Section 5.5 are (i) intended to be for the benefit of, and will be enforceable by, each Indemnified Person and each other person entitled to the benefit of Sections 5.5(a) and (b) of this Agreement, his or her heirs and his or her representatives and (ii) in addition to, and not in substitution for, any other rights to indemnification or contribution that any such person may have by contract or otherwise.

SECTION 5.6 Fees and Expenses.

(a) Except as provided in this Section 5.6, all fees and expenses incurred in connection with the Merger, this Agreement and the transactions contemplated by this Agreement shall be paid by the party incurring such fees or expenses, whether or not the Merger is consummated.

(b) The Company shall pay Parent a fee of $58 million (the “Termination Fee”), if this Agreement is terminated:

(i) pursuant to Section 7.1(b)(i), 7.1(b)(iii) or 7.1(c), and prior to such termination a Takeover Proposal shall have been publicly disclosed and, except with respect to a Takeover Proposal that is consummated or with respect to which an Acquisition Agreement is entered into by the Company or any of its Subsidiaries during the nine-month period following such termination (a “Subsequent Takeover Proposal”), not withdrawn or any person shall have publicly announced an intention (whether or not conditional) to make a Takeover Proposal and, except with respect to a Subsequent Takeover Proposal, not withdrawn such intention, and within nine months of such termination the Company or any of its Subsidiaries enters into any Acquisition Agreement related to any Takeover Proposal (and the Takeover Proposal set forth in such Acquisition Agreement is subsequently consummated, whether during or after such nine-month period) or consummates a Takeover Proposal (for the purposes of the foregoing (and Section 7.1(e)) the terms “Acquisition Agreement” and “Takeover Proposal” shall have the meanings assigned to such terms in Section 4.2 of this Agreement except that the references to “10%” in the definition of “Takeover Proposal” in Section 4.2(a) of this Agreement shall be deemed to be references to “50%”);

(ii) pursuant to Section 7.1(e); or

(iii) pursuant to Section 7.1(f).

(c) The Termination Fee shall be payable by wire transfer of same day funds immediately upon termination pursuant to Section 7.1(f), within two Business Days of termination pursuant to Section 7.1(e), and upon consummation of a Takeover Proposal after termination pursuant to the circumstances described in Section 5.6(b)(i).

(d) The Company acknowledges that the agreements contained in Section 5.5(b) of this Agreement are an integral part of the transactions contemplated by this Agreement, and that, without these agreements, Parent would not enter into this Agreement; accordingly, if the Company fails promptly to pay the amount due pursuant to Section 5.5(b) of this Agreement, and, in order to obtain such payment, Parent commences a suit that results in a judgment against the Company for the fees set forth in Section 5.5(b) of this Agreement, the Company shall pay to Parent its costs and expenses (including attorneys’ fees and expenses) in connection with such suit, together with interest on the amount of the fee at the prime rate of Bank of America, N.A. in effect on the date such payment was required to be made.

SECTION 5.7 Public Announcements. The Company and Parent each shall consult with the other prior to issuing any press releases or otherwise making public announcements with respect to the Merger and the other transactions contemplated hereby and prior to making any filings with any third party and/or any Governmental Entity with respect thereto, except as may be required by Law or by obligations pursuant to any listing agreement with or rules of any national securities exchange or national market system on which such party’s securities are listed or traded, in which case the party required to make the release or announcement shall consult with the other to the extent practicable. The parties agree that the initial press release to be issued with respect to the transactions contemplated by this Agreement shall be in the form heretofore agreed to by the parties.

SECTION 5.8 Rights Agreement. The Board of Directors of the Company shall take all further action reasonably requested by Parent in order to render the Rights issued pursuant to the Rights Agreement inapplicable to the Merger and the other transactions contemplated by this Agreement.

SECTION 5.9 Conduct of Parent. During the period from the date of this Agreement to the earlier of the Effective Time and the termination of this Agreement in accordance with the terms hereof, except as consented to in writing by the Company, none of Parent or any of its Subsidiaries shall make any acquisition that is reasonably likely to (i) materially impair Parent’s ability to consummate the transactions contemplated by this Agreement or (ii) cause a material delay of the Merger.

SECTION 5.10 Section 16 Matters. Prior to the Effective Time, the Company shall take all such steps as may be required to cause any dispositions of Company Common Stock (including derivative securities with respect to Company Common Stock) resulting from the transactions contemplated by this Agreement by each individual who is subject to the reporting requirements of Section 16(a) of the Exchange Act with respect to the Company, to be exempt under Rule 16b-3 promulgated under the Exchange Act, such steps to be taken in accordance with the No-Action Letter dated January 12, 1999, issued by the SEC to Skadden, Arps, Slate, Xxxxxxx & Xxxx LLP.

SECTION 5.11 Notice of Certain Events. The Company shall promptly notify Parent of, and furnish Parent with any information it may reasonably request with respect to, (i) any representation or warranty becoming untrue such that the condition set forth in Section 6.2(a) would not be satisfied, or (ii) the failure by the Company to comply with any of its covenants such that the condition set forth in Section 6.2(b) would not be satisfied; provided, however, that in no event will the failure of the Company to deliver notice to Parent pursuant to clause (i) be considered a failure of the condition set forth in Section 6.2(b) or a basis for termination pursuant to Section 7.1(c) as it relates to a breach of covenants. The Company’s satisfaction of its obligations under this Section 5.11 shall not relieve the Company of its obligations under this Agreement and no information delivered to Parent pursuant to this Section 5.11 shall update the Disclosure Schedule.

SECTION 8.8 Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF DELAWARE, REGARDLESS OF THE LAWS THAT MIGHT OTHERWISE GOVERN UNDER APPLICABLE PRINCIPLES OF CONFLICTS OF LAWS THEREOF.

SECTION 8.9 Assignment. This Agreement shall not be assignable by operation of law or otherwise; provided, however, that Parent may designate, by written notice to the Company, another Subsidiary of Parent to be a constituent corporation in lieu of Sub, whereupon all references herein to Sub shall be deemed references to such other Subsidiary, except that all representations and warranties made herein with respect to Sub as of the date of his Agreement shall be deemed representations and warranties made with respect to such other Subsidiary as of the date of such designation.

SECTION 8.10 Specific Enforcement; Consent to Jurisdiction. The parties agree that irreparable damage would occur and that the parties would not have any adequate remedy at law in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement in any Federal court located in the State of Delaware or in any state court in the State of Delaware, this being in addition to any other remedy to which they are entitled at law or in equity. In addition, each of the parties hereto (a)

consents to submit itself to the personal jurisdiction of any Federal court located in the State of Delaware or of any state court located in the State of Delaware in the event any dispute arises out of this Agreement or the transactions contemplated by this Agreement, (b) agrees that it will not attempt to deny or defeat such personal jurisdiction by motion or other request for leave from any such court and (c) agrees that it will not bring any action relating to this Agreement or the transactions contemplated by this Agreement in any court other than a Federal court located in the State of Delaware or a state court located in the State of Delaware.

SECTION 8.11 Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule of law or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible to the fullest extent permitted by applicable law in an acceptable manner to the end that the transactions contemplated hereby are fulfilled to the extent possible.
