(b) Subject to the provisions of Article X, the closing of the Merger (the “Closing”) shall take place at the offices of Shearman & Sterling LLP, Commerce Court West, Suite 4405, Toronto, Ontario, Canada, as soon as practicable, but in no event later than the second Business Day after satisfaction or, to the extent permitted hereunder, waiver of all conditions to the Merger, or at such other place or time as Parent and the Company may mutually agree. In connection with the Closing, the Company and Merger Sub shall file a certificate of merger with the Delaware Secretary of State. The Merger shall become effective at such time (the “Effective Time”) as the certificate of merger is duly filed with the Delaware Secretary of State (or at such later time as is set forth in the certificate of merger).

(c) From and after the Effective Time, the Surviving Corporation shall possess all the rights, powers, privileges and immunities and be subject to all of the duties and liabilities, restrictions and disabilities of the Company and Merger Sub, all as provided under Delaware Law.

Section 2.02 Conversion of Shares. At the Effective Time,

(a) except as otherwise provided in Section 2.04, each share of Company Stock outstanding immediately prior to the Effective Time (other than any shares of Company Stock canceled pursuant to Section 2.02(b) and any shares of Company Stock with respect to which appraisal rights are properly asserted in accordance with Delaware Law) shall be canceled and converted into the right to receive $25.60 in cash, without interest (the “Merger Consideration”), upon surrender thereof in the manner provided in Section 2.03;

(b) each share of Company Stock owned by the Company, Parent, Merger Sub or any of their respective Subsidiaries immediately prior to the Effective Time shall be canceled, and no payment shall be made with respect thereto; and

(c) each share of common stock, par value $0.01 per share, of Merger Sub outstanding immediately prior to the Effective Time shall be converted into and become one share of common stock, par value $0.01 per share, of the Surviving Corporation with the same rights, powers and privileges as the shares so converted and from and after the Effective Time shall constitute the only outstanding shares of capital stock of the Surviving Corporation.

Section 2.03 Surrender and Payment.

(a) Prior to the Effective Time, Parent shall appoint an agent (the “Paying Agent”) for the purpose of exchanging the (i) certificates representing shares of Company Stock (the “Certificates”) or (ii) uncertificated shares of Company Stock (the “Uncertificated Shares”), in each case, for the aggregate Merger Consideration payable to each holder of shares of Company Stock. As promptly as practicable after the Effective Time (but in any event within one Business Day after the Closing Date), Parent shall deliver to the Paying Agent the cash necessary to pay the full amount of the Merger Consideration in respect of the Certificates and the Uncertificated Shares as such Certificates and the Uncertificated Shares are surrendered for payment pursuant to this Section 2.03. Promptly after the date of the Closing, Parent shall cause the Paying Agent to send to each Person who held of record shares of Company Stock immediately prior to the Effective Time a letter of transmittal and instructions (which shall specify that the delivery shall be effected, and risk of loss and title shall pass, only upon proper delivery of the Certificates or transfer of the Uncertificated Shares to the Paying Agent) for use in such exchange.

(b) Each holder of shares of Company Stock that have been converted into the right to receive the Merger Consideration shall be entitled to receive, upon (i) surrender of a Certificate to the Paying Agent, together with a properly completed and validly executed letter of transmittal and such other documents as may be required by the Paying Agent, or (ii) receipt of an “agent’s message” by the Paying Agent (or such other evidence, if any, of transfer as the Paying Agent may reasonably request) in the case of a book-entry transfer of Uncertificated Shares, the Merger Consideration in respect of the shares of Company Stock represented by such Certificate or book entry and, upon payment therefor, such shares of Company Stock will be canceled. No interest shall accrue or be paid on the Merger Consideration payable upon the surrender of any Certificate or Uncertificated Share for the benefit of the holder of such Certificate or Uncertificated Share. Until so surrendered or transferred, as the case may be, each such Certificate or Uncertificated Share shall represent after the Effective Time for all purposes only the right to receive such Merger Consideration and shall cease to have any rights with respect to such shares of Company Stock, except as otherwise provided herein or by Applicable Law.

(c) If any portion of the Merger Consideration is to be paid to a Person other than the Person in whose name the surrendered Certificate or the transferred Uncertificated Share is registered, it shall be a condition to such payment that (i) either such Certificate shall be properly endorsed or shall otherwise be in proper form for transfer or such Uncertificated Share shall be properly transferred and (ii) the Person requesting such payment shall pay to the Paying Agent any transfer or other taxes required as a result of such payment to a Person other than the registered holder of such Certificate or Uncertificated Share or establish to the satisfaction of the Paying Agent that such tax has been paid or is not payable.

(d) From and after the Effective Time, there shall be no further registration of transfers of shares of Company Stock. If, after the Effective Time, Certificates or Uncertificated Shares are presented to the Surviving Corporation, they shall be canceled and exchanged for the Merger Consideration provided for, and in accordance with the procedures set forth, in this Article II.

(e) Any portion of the Merger Consideration made available to the Paying Agent pursuant to Section 2.03(a) that remains unclaimed by the holders of shares of Company Stock nine months after the Effective Time shall be returned to Parent, upon demand, and any such holder who has not exchanged shares of Company Stock for the Merger Consideration in accordance with this Section 2.03 prior to that time shall thereafter look only to Parent, as general creditors thereof, for payment of the Merger Consideration, and any dividends and distributions with respect thereto, in respect of such shares without any interest thereon. Notwithstanding the foregoing, Parent shall not be liable to any holder of shares of Company Stock for any amounts paid over to a public official pursuant to applicable abandoned property, escheat or similar laws. Any amounts remaining unclaimed by holders of shares of Company Stock two years after the Effective Time (or such earlier date, immediately prior to such time when the amounts would otherwise escheat to or become property of any Governmental Authority) shall become, to the extent permitted by Applicable Law, the property of Parent free and clear of any claims or interest of any Person previously entitled thereto.

Section 2.04 Appraisal Rights.

(a) Notwithstanding anything to the contrary contained in this Agreement, any share of the Company Stock that, as of the Effective Time, is held by a holder who properly asserts and perfects such holder’s appraisal rights under Section 262 of Delaware Law with respect to such share, shall not be converted into or represent the right to receive the Merger Consideration in accordance with Section 2.02(a), and the holder of such share instead shall be entitled only to such rights as may be granted to such holder pursuant to Section 262 of Delaware Law with respect to such share; provided, however, that if such appraisal rights shall not be perfected or the holder of such share shall otherwise lose such holder’s appraisal rights with respect to such share, then, as of the later of the Effective Time or the time of the failure to perfect such rights or the loss of such rights, such share shall automatically be converted into and shall thereafter represent only the right to receive (upon the surrender of any Certificate representing such share) the Merger Consideration, without any interest thereon, in accordance with Section 2.02(a).

(b) The Company shall give Parent (i) prompt notice of any written demand for appraisal received by the Company prior to the Effective Time pursuant to Section 262 of Delaware Law and of any similar demand, notice or instrument delivered to the Company prior to the Effective Time pursuant to Delaware Law and (ii) the opportunity to direct all negotiations and proceedings with respect to any such demand, notice or instrument. Without limiting the generality of the foregoing, the Company shall not make any payment or settlement offer prior to the Effective Time with respect to any such demand unless Parent shall have consented in writing to such payment or settlement offer or unless required by a final, non-appealable order, decree, ruling or injunction of a court of competent jurisdiction.

Section 2.05 Stock Options and Awards. At or immediately prior to the Effective Time, each option or award (a “Company Stock Award”) to purchase shares of Company Stock granted under the 1997 Employee Stock Purchase Plan (the “Employee Stock Purchase Plan”), the 1990 Directors’ Stock Option Plan, the 1994 Long-Term Incentive Plan, the 1997 Long-Term Incentive Plan and the Acquisition Stock Option Plan (each, a “Company Equity Incentive Plan”), whether or not then vested or exercisable, shall be canceled, and Parent shall, or shall

cause the Surviving Corporation to, pay each holder of any such option or award at or promptly after the Effective Time for each such option or award an amount in cash determined by multiplying (i) the excess, if any, of the Merger Consideration per share of Company Stock over the applicable exercise price of such option or award by (ii) the number of shares of Company Stock such holder could have purchased (assuming full vesting of such option or award) had such holder exercised such option or award in full immediately prior to the Effective Time. Prior to the Effective Time, the Company shall use its reasonable best efforts to take all actions necessary under each such Company Equity Incentive Plan and any agreement relating to each such Company Stock Award to effect the foregoing treatment of such option or award. For the purposes of the Employee Stock Purchase Plan, the offering period in effect at the Effective Time shall terminate as of the Effective Time, each participant shall be deemed to have options equal to the amount such participant is entitled to based on such participant’s accumulated payroll deductions as of the Effective Time, and such options shall be cashed out pursuant to this Section 2.05.

Section 2.06 Withholding Rights. Each of Parent and the Surviving Corporation shall be entitled to deduct and withhold from the consideration otherwise payable to any Person pursuant to this Article II such amounts as it is required to deduct and withhold with respect to the making of such payment under any provision of federal, state, local or foreign tax law. If the Surviving Corporation or Parent, as the case may be, so withholds such amounts, such amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the shares of Company Stock or any Company Stock Award pursuant to Sections 2.02(a) and 2.05 in respect of which the Surviving Corporation or Parent, as the case may be, made such deduction and withholding.

Section 2.07 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 required by the Surviving Corporation, the posting by such Person of a bond, in such reasonable amount as the Surviving Corporation may direct, as indemnity against any claim that may be made against it with respect to such Certificate, the Paying Agent will pay, in exchange for such lost, stolen or destroyed Certificate, the Merger Consideration to be paid in respect of the shares of Company Stock represented by such Certificate, as contemplated by this Article II.

Section 2.08 Adjustments. If, during the period between the date of this Agreement and the Effective Time, any change in the outstanding shares of Company Stock shall occur, including by reason of any reclassification, recapitalization, stock split or combination, exchange or readjustment of shares, or any stock dividend thereon with a record date during such period (but excluding any change that results from any exercise of Company Stock Awards outstanding as of the date hereof under Company Equity Incentive Plans), the Merger Consideration shall be appropriately adjusted; provided that, in the event of such adjustment, the aggregate amount of Merger Consideration payable pursuant to this Article II shall not be adjusted.

The Company shall immediately cease and cause to be terminated any existing solicitation, encouragement, discussion, negotiation or other action conducted by the Company, any Company Subsidiary or any of its or their officers, directors, employees, investment bankers, attorneys, accountants, consultants or other agents or advisors with respect to any Acquisition Proposal. The Company shall not release any third party from, or waive any provision of, any confidentiality or standstill agreement to which it is a party and the Company also agrees to promptly request each person that has executed a confidentiality agreement within 12 months prior to the date hereof (other

than Steven G.

The Company shall not take any action to make the provisions of Section 203 of Delaware Law inapplicable to any transaction other than the transactions contemplated by this Agreement.

(b) Notwithstanding anything in Section 6.03(a) (except as set forth in clause (i) below), but subject to Sections 6.03(c) and 6.03(e) below, from the date hereof and prior to the Company Stockholder Meeting, the Board of Directors of the Company may, directly or indirectly through advisors, agents or other intermediaries, (i) engage in negotiations or discussions with any Third Party that, subject to the Company’s compliance with Section 6.03(a), has made a bona fide Acquisition Proposal that the Board of Directors of the Company, acting in good faith (after considering the advice of the Company’s outside legal advisor and financial advisor) has determined to be, or reasonably likely to lead to, a Superior Proposal, (ii) furnish to such Third Party information relating to the Company or any of its Subsidiaries pursuant to an appropriate confidentiality agreement (which shall be (i) with respect to Vector Capital Corporation, on the terms as set forth in the confidentiality agreement currently in effect between the Company and Vector Capital Corporation or (ii) with respect to any other Third Party, on terms no less favorable to the Company than those contained in the Confidentiality Agreement (as defined below) and it being understood that such confidentiality agreement and any related agreements shall not include any provision calling for an exclusive right to negotiate with such Third Party or having the effect of prohibiting the Company from satisfying its obligations under this Agreement) and (iii) make an Adverse Recommendation Change but, in each case referred to in the foregoing clauses (i) through (iii), only if the Board of Directors of the Company determines in good faith by a majority vote (exclusive of any members of the Board of Directors of the Company that are not independent of the Third Parties making such Superior Proposal), after considering advice from outside legal counsel to the Company and the financial advisor to the Company, that such action is reasonably necessary to comply with its fiduciary duties under Applicable Law.

(c) The Company shall notify Parent as promptly as reasonably practicable following receipt by the Company (or any of its advisors) of any Acquisition Proposal (or any inquiry or contact with any Person with respect thereto), which notice shall include the identity of such Person and the material terms and conditions of any such Acquisition Proposal. The Company shall keep Parent informed on a reasonably current basis of the status of any Acquisition Proposal, including with respect to the material terms of any such proposal and whether such proposal has been withdrawn or rejected. The Board of Directors of the Company shall not take any of the actions referred to in clauses (i) or (ii) of Section 6.03(b) or clauses (i) or (ii) of Section 6.03(e) unless the Company shall have first delivered to Parent written notice advising Parent that it intends to take such action, which written notice shall state the material terms and conditions of the applicable Superior Proposal (including material amendments or proposed material amendments). The Company shall provide to Parent any material information regarding the Company (not theretofore provided or made available to Parent) that it provides to any Third Party pursuant to Section 6.03(b)(ii) or Steven E. Mihaylo, his affiliates or his

potential sources of debt or equity financing pursuant to Section 6.03(e) as promptly as reasonably practicable after the Company provides such information to such Person. The Company shall provide Parent with 24 hours’ prior notice (or such shorter prior notice as is provided to the members of the Board of Directors of the Company) of any meeting of the Board of Directors of the Company at which it is reasonably expected that an Acquisition Proposal will be considered. The parties hereto agree that, in the event that the Board of Directors of the Company determines it is reasonably necessary to take the action referred to in clause (iii) of Section 6.03(b), the Board of Directors of the Company may take such action, but only (i) after providing written notice to Parent (a “Notice of Superior Proposal”) advising Parent that the Company has received a Superior Proposal, specifying the material terms and conditions of such Superior Proposal and identifying the person making such Superior Proposal and indicating that the Board of Directors of the Company intends to effect an Adverse Recommendation Change, and (ii) if Parent does not, within four Business Days after Parent’s receipt of the Notice of Superior Proposal, make an offer that the Board of Directors of the Company determines, in its good faith judgment (after considering the advice of its financial advisor) to be at least as favorable to the Company’s stockholders as such Superior Proposal.

(d) Notwithstanding the foregoing, the Board of Directors of the Company shall be permitted to take any action necessary to comply with Rule 14d-9 or Rule 14e-2(a) under the 1934 Act with regard to an Acquisition Proposal and to make any disclosure to the stockholders of the Company if, in the good faith judgment of the Board of Directors of the Company, after considering the advice of outside counsel, such disclosure is required to comply with its fiduciary obligations to the stockholders of the Company or the Company’s public disclosure obligations under Applicable Law, and provided that such disclosure states that no action will be taken by the Board of Directors of the Company in violation of this Agreement; provided, however, that the fact that a disclosure or other action may be deemed permissible by virtue of this sentence does not in and of itself mean that any such disclosure or other action constitutes an Adverse Recommendation Change unless such disclosure has the effect of withdrawing, qualifying or modifying the Company Board Recommendation in a manner adverse to Parent or Merger Sub or recommending an Acquisition Proposal.

(e) Without limiting the foregoing, it is understood that any violation of the restrictions set forth in this Section 6.03 by any officer, director, employee, investment bankers, attorneys, accountants, consultants, intermediaries, or other agents or advisors of the Company (whether on behalf of or at the direction of the Board of Directors of the Company or otherwise) or any of its Subsidiaries, shall be deemed to be a breach of this Section 6.03 by the Company or the Board of Directors of the Company, as the case may be. Notwithstanding anything in Section 6.03(b) or this Section 6.03(e) to the contrary, but subject to Section 6.03(c), in the event of a submission of an Acquisition Proposal by Steven G. Mihaylo or his Affiliates, from the date hereof and prior to the Company Stockholder Meeting, the Board of Directors of the Company may, directly or indirectly through advisors, agents or other intermediaries, (i) engage in negotiations or discussions with Mr. Mihaylo and his Affiliates concerning an Acquisition Proposal or (ii) furnish to Mr. Mihaylo, his Affiliates and his potential sources of debt and equity financing information relating to the Company or any of its Subsidiaries pursuant to an appropriate confidentiality agreement (which shall be either (i) on the terms as set forth in the confidentiality agreement currently in effect between the Company and Mr. Mihaylo, or (ii) on terms no less favorable to the Company than those contained in the Confidentiality Agreement (as defined below) and it being

understand that such confidentiality agreement and any related agreements shall not include any “standstill” provision or provision calling for an exclusive right to negotiate with Mr. Mihaylo or his Affiliates or having the effect of prohibiting the Company from satisfying its obligations under this Agreement in accordance with its terms).

(f) For the purposes of this Section 6.03 and the definition of “Company Triggering Event” in Section 1.01, the Board of Directors of the Company shall be deemed to include any committee thereof (including the Special Committee) authorized to act on behalf of the Board of Directors of the Company with respect to the matters set forth in this Section 6.03.

Section 6.04 Access to Information, etc. From the date hereof and until the earlier of the Effective Time and the termination of this Agreement in accordance with its terms, neither Parent nor Merger Sub shall communicate with any customer of the Company or its Subsidiaries without the prior consent of the Company; provided, however, that nothing herein shall prohibit Parent or Merger Sub from communicating with its customers, including such customers that are also customers of the Company or its Subsidiaries. From the date hereof until the Effective Time and subject to Applicable Law and the Confidentiality Agreement, dated as of March 1, 2007, between the Company and Parent (the “Confidentiality Agreement”) and Section 8.06 of this Agreement, the Company shall (i) give Parent, its counsel, financial advisors, auditors and other authorized representatives reasonable access during normal business hours, and after reasonable advance notice, to the offices, properties, books and records of the Company and the Subsidiaries, (ii) furnish to Parent, its counsel, financial advisors, auditors and other authorized representatives such financial and operating data and other information as such Persons may reasonably request and (iii) instruct the executive officers, counsel, financial advisors, auditors and other authorized representatives of the Company and its Subsidiaries to cooperate with all reasonable requests of Parent in its investigation of the Company and its Subsidiaries; provided, however, that the foregoing obligation shall not apply to information which would reasonably be expected to jeopardize any legally recognized privilege otherwise relating to such information. Any investigation pursuant to this Section 6.04 shall be conducted in such manner as not to interfere unreasonably with the conduct of the business of the Company and its Subsidiaries. The parties acknowledge and agree that any confidential or proprietary documents or information disclosed or provided pursuant to this Agreement shall be considered subject to and protected from improper or unauthorized use or disclosure by the terms of the Confidentiality Agreement.

Section 6.05 Nasdaq Global Market System and SEC Filings.

(a) The Company shall use reasonable best efforts to cause the continued trading and listing of the Company Stock on the Nasdaq Global Market System during the term of this Agreement; and

(b) The Company shall use reasonable best efforts to file with the SEC its quarterly report on Form 10-Q for the fiscal quarter ended March 31, 2007 in a form compliant with, and within the time period required by, the applicable rules and regulations of the SEC.

Section 6.06 Stockholder Litigation. Each party shall give the other party prompt notice of any actual or potential stockholder litigation against the Company and/or its directors relating to the transactions contemplated by this Agreement, and the Company shall provide Parent with the opportunity to participate in the defense of any such litigation.

Without limiting the generality of the foregoing (and notwithstanding any other provision of this Agreement), prior to the Effective Time and with the prior consent of Parent, the Company shall be entitled to obtain prepaid (or “tail”) insurance policies providing for the coverage contemplated by this Section.

(iii) The certificate of incorporation and bylaws of the Surviving Corporation shall include provisions for exculpation and indemnification of directors and officers equivalent in all material respects to those set forth in the Company’s certificate of incorporation and bylaws in effect as of the date hereof, which provisions shall not be amended for a period of six years after the Effective Time except as required by changes in Applicable Law or except to make changes permitted by Applicable Law that would enlarge the scope of the indemnified persons’ indemnification rights thereunder.

(b) Parent hereby unconditionally and irrevocably covenants and agrees to guarantee the obligations of the Surviving Corporation under this Section 7.01.

COVENANTS OF PARENT, MERGER SUB AND THE COMPANY

Section 8.01 Reasonable Best Efforts.

(a) Subject to the terms and conditions of this Agreement, the Company, Parent and Merger Sub agree to use their respective reasonable best efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary, proper or advisable under Applicable Law to consummate the transactions contemplated by this Agreement, including (i) preparing and filing as promptly as practicable with any Governmental Authority or other Third Party all documentation to effect all necessary filings, notices, petitions, statements, registrations, submissions of information, applications and other documents, (ii) obtaining and maintaining all approvals, consents, registrations, permits, authorizations and other confirmations required to be obtained from any Governmental Authority or other Third Party that are necessary, proper or advisable to consummate the transactions contemplated by this Agreement, and (iii) cooperating in responding to inquiries from, and making presentations to, any Governmental Authorities in connection with the foregoing; provided that the parties hereto understand and agree that the reasonable best efforts of any party hereto shall not be deemed to require (i) entering into any settlement, undertaking, consent decree, stipulation or agreement with any Governmental Authority in connection with the transactions contemplated hereby or (ii) divesting or otherwise holding separate (including by establishing a trust or otherwise), or taking any other action (or otherwise agreeing to do any of the foregoing) with respect to any of its or the Surviving Corporation’s Subsidiaries or any of their respective Affiliates’ businesses, assets or properties.

(b) In furtherance and not in limitation of the foregoing, each of Parent and the Company shall make an appropriate filing of a Notification and Report Form pursuant to the HSR Act with respect to the transactions contemplated hereby as promptly as practicable and in any event within ten Business Days after the date hereof, and each of Parent and the Company shall supply as promptly as practicable any additional information and documentary material that may be requested pursuant to the HSR Act and otherwise take all other actions reasonably necessary to cause the expiration or termination of the applicable waiting periods under the HSR

Act as soon as practicable. In addition, each party agrees to make promptly any filing that may be required with respect to the transactions contemplated by this Agreement under any applicable antitrust, competition or trade regulation law, and to promptly supply any additional information or documentary material that may be requested by any other Governmental Authority.

(i) Each of Parent and Merger Sub shall use their respective reasonable best efforts to arrange and consummate the Financing on substantially the terms and conditions set forth in the Commitment Letters, including using reasonable best efforts to (A) satisfy on a timely basis all terms, conditions, representations and warranties applicable to Parent or Merger Sub in the Commitment Letters, (B) enter into definitive agreements with respect to the Financing as promptly as practicable but in any event at the Effective Time on terms and conditions no less certain than those contained in the Commitment Letters and (C) obtain the funds under the Commitment Letters.

Without the prior written consent of the Company, neither Parent nor any of its Subsidiaries shall knowingly take any action or omit to take any action that reasonably would be expected to materially impair, delay or prevent Parent’s or Merger Sub’s ability to timely obtain the proceeds of the Financing or to enter into and timely consummate any alternate financing arrangement. Parent shall not, without the prior written consent of the Company, terminate, amend or alter, or agree to terminate, amend or alter, the Commitment Letters in a manner that reasonably would materially impair, delay or prevent the transactions contemplated by this Agreement.

Notwithstanding the foregoing, neither the Company nor any of its Subsidiaries shall be required to pay any commitment or other similar fee in connection with the Financing prior to the Effective Time.

(iv) If any portion of the Financing becomes unavailable on the terms and conditions contemplated in the Commitment Letters, Parent shall use its reasonable best efforts to (A) arrange alternate financing (on terms and conditions no less favorable in any material respect than those contained in the Commitment Letters) and, if obtained, shall promptly provide the Company with a copy of the new financing commitments, (B) enter into definitive agreements with respect to any such alternate financing arrangements as promptly as practicable but in any event prior to the Effective Time and (C) obtain funds under such alternate financing arrangements to the extent necessary to consummate the transactions contemplated by this Agreement without undue delay.

Section 8.02 Certain Filings. The Company and Parent shall cooperate with one another (i) in connection with the preparation of the Company Disclosure Documents, (ii) in determining whether any action by or in respect of, or filing with, any Governmental Authority is required, or any actions, consents, approvals or waivers are required to be obtained from parties to any material contracts, in connection with the consummation of the transactions contemplated by this Agreement and (iii) in taking such actions or making any such filings, furnishing information required in connection therewith or with the Company Disclosure Documents and seeking timely to obtain any such actions, consents, approvals or waivers.

Section 8.03 Public Announcements. Parent and the Company shall consult with each other before issuing any press release, making any other public statement or scheduling any press conference or conference call with investors or analysts with respect to this Agreement or the transactions contemplated hereby and, except as may be required by Applicable Law or any listing agreement with or rule of any automated quotation system or national securities exchange or association, shall not issue any such press release, make any such other public statement or schedule any such press conference or conference call before such consultation, if practicable.

Section 8.04 Further Assurances. At and after the Effective Time, the officers and directors of the Surviving Corporation shall be authorized to execute and deliver, in the name and on behalf of the Company or Merger Sub, any deeds, bills of sale, assignments or assurances and to take and do, in the name and on behalf of the Company or Merger Sub, any other actions and things to vest, perfect or confirm of record or otherwise in the Surviving Corporation any and all right, title and interest in, to and under any of the rights, properties or assets of the Company acquired or to be acquired by the Surviving Corporation as a result of, or in connection with, the Merger.

Section 8.05 Notice of Certain Events. Each of the Company, on the one hand, and Parent or Merger Sub, on the other hand, shall promptly notify the other if it receives or becomes aware of:

(a) any notice or other communication from any Person alleging that the consent of such Person is or may be required in connection with the transactions contemplated by this Agreement;

(b) any notice or other communication from any Governmental Authority in connection with the transactions contemplated by this Agreement;

(c) any actions, suits, claims, investigations or proceedings commenced or threatened against, relating to or involving or otherwise affecting the Company or any of its Subsidiaries or Parent or any of its Subsidiaries, as the case may be, that, if pending on the date of this Agreement, would have been required to have been disclosed pursuant to Articles IV or V, as the case may be, or that relate to the consummation of the transactions contemplated by this Agreement;

(d) any inaccuracy of any representation or warranty that could reasonably be expected to cause any of the conditions set forth in Section 9.02 or 9.03 not to be satisfied; and

(e) any failure of any party hereto to comply with or satisfy any covenant, condition or agreement to be complied with or satisfied by it hereunder; provided, however, that the delivery of any notice pursuant to this Section 8.05 shall not limit or otherwise affect the remedies available hereunder to the party receiving that notice.

Section 8.06 Company Disclosure Schedule. A disclosure or statement in the Company Disclosure Schedule shall not be construed as indicating that such matter is material, has resulted in or could have resulted in a Company Material Adverse Effect or is necessarily required to be disclosed by the Company. No disclosure in the Company Disclosure Schedule relating to any possible breach or violation of any agreement, law or regulation shall be construed as an admission or indication that any such breach or violation exists or has actually occurred.

(a) by mutual written agreement of the Company and Parent;

(b) by either the Company or Parent, if:

(i) the Merger has not been consummated on or before September 30, 2007 (the “End Date”); provided, that the right to terminate this Agreement pursuant to this Section 10.01(b)(i) shall not be available to any party whose breach of any provision of this Agreement results in the failure of the Merger to be consummated by such time;

(f) by the Company, upon a breach of any representation, warranty, covenant or agreement on the part of Parent and Merger Sub set forth in this Agreement, or if any representation or warranty of Parent and Merger Sub shall have become untrue, in either case such that the conditions set forth in Section 9.03(a) and Section 9.03(b) would not be satisfied

Section 11.02 Survival of Representations and Warranties. The representations and warranties contained herein and in any certificate or other writing delivered pursuant hereto shall not survive the Effective Time.

Section 11.03 Amendments and Waivers.

(a) Any provision of this Agreement may be amended or waived prior to the Effective Time if, but only if, such amendment or waiver is in writing and is signed, in the case of an amendment, by each party to this Agreement or, in the case of a waiver, by each party against whom the waiver is to be effective; provided that, after the Company Stockholder Approval and without the further approval of the stockholders of the Company, no such amendment or waiver shall reduce the amount or change the kind of consideration to be paid or received pursuant to Section 2.02, Section 2.03 or Sections 2.05 through 2.08.

(b) No failure or delay by any party in exercising any right, power or privilege hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The rights and remedies herein provided shall be cumulative and not exclusive of any rights or remedies provided by Applicable Law.

Section 11.04 Fees and Expenses.

(a) Except as otherwise provided herein, all costs and expenses incurred in connection with this Agreement shall be paid by the party incurring such cost or expense.

(b) If a Parent Payment Event occurs, the Company shall pay Parent a fee of $20,000,000 less the amount of Parent Expenses, if any, reimbursed by the Company to Parent in connection with a Parent Reimbursement Event (the “Parent Termination Fee”) on the earlier of (i) simultaneously with the Company’s termination of this Agreement pursuant to Section 10.01(e), (ii) immediately prior to the execution of a definitive agreement with respect to an Alternative Transaction in the event that this Agreement is terminated under the circumstances described in the proviso in the definition of “Parent Payment Event”, or (iii) within one Business Day after the Parent Payment Event relating to the termination of this Agreement pursuant to Section 10.01(c). If a Parent Reimbursement Event occurs, the Company shall reimburse Parent and Merger Sub within five Business Days after the Parent Reimbursement Event for all Parent Expenses in an amount not to exceed $6,000,000. In no event shall the Company pay more than one Parent Termination Fee hereunder and in no event shall the Company be obligated to reimburse Parent for Parent Expenses resulting from more than one Parent Reimbursement Event.

(c) If a Company Payment Event occurs, Parent shall within one Business Day following such Company Payment Event pay the Company (by wire transfer of immediately available funds) a fee of $20,000,000 (the “Company Termination Fee”). In no event shall Parent pay more than one Company Termination Fee hereunder.

(d) The parties hereto acknowledge that the agreements contained in this Section 11.04 are an integral part of the transactions contemplated by this Agreement. In the event that the Company shall fail to pay the Parent Termination Fee or any Parent Expenses when due, the term “Parent Termination Fee” and “Parent Expenses”, as the case may be, shall be deemed to include the costs and expenses actually incurred or accrued by Parent (including, without limitation, fees and expenses of counsel) in connection with the collection under and

enforcement of this Section 11.04, together with interest on such unpaid Parent Termination Fee and Parent Expenses, commencing on the date that the Parent Termination Fee or such Parent Expenses became due, at a rate equal to the rate of interest publicly announced by Citibank, N.A., from time to time, in The City of New York, as such bank’s Prime Rate plus 1.00%. In the event that Parent shall fail to pay the Company Termination Fee when due, the term “Company Termination Fee” shall be deemed to include the costs and expenses actually incurred or accrued by the Company (including, without limitation, fees and expenses of counsel) in connection with the collection under and enforcement of this Section 11.04, together with interest on such unpaid Company Termination Fee, commencing on the date that the Company Termination Fee became due, at a rate equal to the rate of interest publicly announced by Citibank, N.A., from time to time, in The City of New York as such bank’s Prime Rate plus 1.00%. The parties further acknowledge and agree that in the event of the circumstances giving rise to the payment of the Parent Termination Fee or any Parent Expenses or the Company Termination Fee, damages from such circumstances will be difficult to quantify. Therefore the parties have agreed that the payment of such amounts represents a reasonable estimate of the amount of such damages in such contexts and that such payments shall be deemed to constitute liquidated damages and not in the nature of a penalty. The parties acknowledge and agree that the sole and exclusive remedy in the circumstances giving rise to the payment of the Parent Termination Fee, any Parent Expenses or the Company Termination Fee, as the case may be, shall be the payment of such agreed amounts, and no party shall have any other or further liability to any other party arising out of the circumstances triggering payment of such fees and reimbursement of expenses.

(e) Payment of one-half the Company Termination Fee, to the extent due and payable hereunder, is and shall be separately guaranteed pursuant to the Limited Guarantee entered into by Francisco Partners II, L.P. on the date hereof.

Section 11.05 Binding Effect; Benefit; Assignment.

(a) The provisions of this Agreement shall be binding upon and shall inure to the benefit of the parties hereto and the third party beneficiaries identified in Section 7.01 and their respective successors and assigns. Except as provided in Section 7.01, no provision of this Agreement is intended to confer any rights, benefits, remedies, obligations or liabilities hereunder upon any Person other than the parties hereto and their respective successors and assigns. Nothing in this Agreement shall be interpreted to amend any benefit plan or to limit any rights that any parties may have under a benefit plan to amend or terminate that plan.

(b) No party may assign, delegate or otherwise transfer any of its rights or obligations under this Agreement without the consent of each other party hereto, except that Parent or Merger Sub may transfer or assign its rights and obligations under this Agreement, in whole or from time to time in part, to (i) one or more of their Affiliates at any time and (ii) on or after the Effective Time, to any Person (including lenders in connection with the Financing for collateral security purposes); provided that no such transfer or assignment shall relieve Parent or Merger Sub from any of its obligations hereunder.

Section 11.06 Governing Law. This Agreement shall be governed by, and construed in accordance with, the internal laws of the State of New York, without regard to the conflict of law

provisions thereof, provided that the Merger shall be effected in accordance with the applicable provisions of Delaware Law.

Section 11.07 Jurisdiction. The parties hereto agree that any suit, action or proceeding seeking to enforce any provision of, or based on any matter arising out of or in connection with, this Agreement or the transactions contemplated hereby shall be brought in any federal court or state court located in the City of New York in the State of New York, and each of the parties hereby irrevocably consents to the jurisdiction of such courts (and of the appropriate appellate courts therefrom) in any such suit, action or proceeding and irrevocably waives, to the fullest extent permitted by law, any objection that it may now or hereafter have to the laying of the venue of any such suit, action or proceeding in any such court or that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum. Process in any such suit, action or proceeding may be served on any party anywhere in the world, whether within or without the jurisdiction of any such court. Without limiting the foregoing, each party agrees that service of process on such party as provided for notices in Section 11.01 shall be deemed effective service of process on such party.

Section 11.08 Counterparts; Effectiveness. This Agreement may be signed in any number of counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. This Agreement shall become effective when each party hereto shall have received a counterpart hereof signed by all of the other parties hereto. Until and unless each party has received a counterpart hereof signed by the other party hereto, this Agreement shall have no effect and no party shall have any right or obligation hereunder.

Section 11.09 Entire Agreement. This Agreement, the Confidentiality Agreement and any other written agreements executed and delivered by the parties hereto on the date hereof constitute the entire agreement between the parties with respect to their collective subject matter and supersede all prior agreements and understandings, both oral and written, between the parties with respect to such subject matter.

Section 11.10 Severability. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction or other Governmental Authority to be invalid, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions of this Agreement shall remain in full force and effect and shall in no way be affected, impaired or invalidated so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party. Upon such a determination, the parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner in order that the transactions contemplated hereby be consummated as originally contemplated to the fullest extent possible.

Section 11.11 Specific Performance. The parties hereto agree that irreparable damage would occur if any obligation of the Company under provision of this Agreement were not performed in accordance with the terms hereof and that, prior to the termination of this Agreement in accordance with Section 10.01 hereof, the parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement by the Company or to enforce specifically the performance of the terms and provisions hereof by the Company in any federal or state court

located in the City of New York in the State of New York, in addition to any other remedy to which they are entitled at law or in equity.

Section 11.12 WAIVER OF JURY TRIAL. EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.
