ARTICLE I

THE MERGER

1.1 The Merger.

On the terms and subject to the conditions set forth in this Agreement, and in accordance with Delaware Law, at the Effective Time, Acquiror Sub shall be merged with and into the Company, with the Company being the surviving corporation (the “Surviving Corporation”) in the Merger. Upon consummation of the Merger, the separate corporate existence of Acquiror Sub shall cease, and the Surviving Corporation shall continue to exist as a Delaware corporation.

1.2 Closing.

Subject to the terms and conditions of this Agreement, the closing of the Merger (the “Closing”) shall take place at the offices of ▇▇▇▇▇ & ▇▇▇▇▇▇▇ L.L.P., located at One ▇▇▇▇▇ Center, ▇▇▇▇ ▇▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇ ▇▇▇▇▇ (or at such other place as the Parties may designate in writing) at 10:00 a.m. (Mountain time) on a date to be specified by the Parties (the “Closing Date”), which date shall be no later than the third Business Day after satisfaction or waiver of the conditions set forth in Article IX (other than conditions that by their nature are to be satisfied at the Closing, but subject to the satisfaction or waiver of those conditions at such time), unless another time, date or place is agreed to in writing by the Parties hereto.

1.3 Effective Time; Closing Date.

Subject to the provisions of Section 1.2, as promptly as practicable after the satisfaction or, if permissible, waiver of the conditions set forth in Article IX, the Surviving Corporation shall cause the Merger to be consummated by filing the Certificate of Merger, attached hereto as Exhibit B (the “Certificate of Merger”), and any other appropriate documents with the Secretary of State of the State of Delaware, in such form as required by, and executed in accordance with the relevant provisions of, Delaware Law (the date and time of such filing being the “Effective Time”).

1.4 Effect of the Merger.

At the Effective Time, the effect of the Merger shall be as set forth under Delaware Law. Without limiting the generality of the foregoing, and subject thereto, at the Effective Time, all the property, rights, privileges, powers and franchises of the Company and Acquiror Sub shall vest in the Surviving Corporation, and all debts, liabilities and duties of the Company and Acquiror Sub shall become the debts, liabilities and duties of the Surviving Corporation.

1.5 Certificate of Incorporation; Bylaws.

(a) The certificate of incorporation of Acquiror Sub as in effect immediately prior to the Effective Time shall be the certificate of incorporation of the Surviving Corporation, except that the corporate name of the Company shall become the corporate name of the Surviving Corporation, until thereafter changed or amended as provided therein or by applicable Law.

(b) The bylaws of Acquiror Sub as in effect immediately prior to the Effective Time shall be the bylaws of the Surviving Corporation, until thereafter changed or amended as provided therein or by applicable Law.

1.6 Directors and Officers.

At the Effective Time, the officers and directors of Acquiror Sub immediately prior to the Effective Time shall be the officers and directors of the Surviving Corporation, in each case until their respective successors are duly elected or appointed and qualified or until the earlier of their death, resignation or removal.

1.7 Taking of Necessary Action; Further Action.

If, at any time after the Effective Time, any further action is necessary or desirable to carry out the purposes of this Agreement and to vest the Surviving Corporation with full right, title and possession to all assets, property, rights, privileges, powers and franchises of the Company and Acquiror Sub, the officers and directors of the Company, Acquiror and Acquiror Sub are fully authorized in the name of their respective corporations or otherwise to take, and will take, all such lawful and necessary action.

ARTICLE II

MERGER CONSIDERATION; CONVERSION OF SECURITIES

2.1 Total Merger Consideration.

The aggregate consideration shall be an amount equal to One Hundred Thirty-Nine Million One Hundred Thousand and No/100 Dollars ($139,100,000) consisting solely of cash (the “Total Merger Consideration”).

2.2 Intentionally Omitted.

2.3 Effect on Capital Stock.

(a) As of the Effective Time, by virtue of the Merger and without any action on the part of the Company, Acquiror or Acquiror Sub or the shareholders thereof, all shares of common stock, par value $0.01 per share, of the Company (the “Common Stock”) issued and outstanding prior to the Effective Time (excluding shares held by shareholders who perfect their dissenters’ rights as provided in Section 2.3(e) and shares to be cancelled pursuant to Section 2.3(d) hereof) shall be converted into the right to receive an amount of cash equal to the Per Share Merger Consideration, without interest.

(b) At the Effective Time, each option granted by the Company under the Company’s 2006 Equity Incentive Plan, 1999 Director Option Plan or any other stock option plan or similar employee benefit plan or arrangement maintained or sponsored by the Company

providing for equity compensation to any Person (collectively, the “Company Equity Incentive Plans”), other than the Company ESPP, or otherwise pursuant to certain inducement grants to purchase Common Stock (each a “Company Option” and collectively, the “Company Options”) that is outstanding and unexercised, as accelerated in accordance with Section 5.5(b), immediately prior the Effective Time, by virtue of the Merger and without any action on the part of the Company, Acquiror, Acquiror Sub or any of the holders thereof, shall be cancelled and, if the Per Share Merger Consideration exceeds the per share exercise price of such Company Option (an “In-the-Money Option”) such Company Option shall be converted into the right to receive, as soon as practicable thereafter but in any event within three (3) Business Days after the Effective Time, an amount of cash equal to the excess, if any, of the Per Share Merger Consideration over the exercise price of such In-the-Money Option (the “Option Merger Consideration”) minus any applicable withholding taxes. Prior to the Effective Time, the Company and its Board shall take any and all actions necessary to effectuate this Section 2.3(b), including the approval of any amendments to the Company Equity Incentive Plans and, including, but not limited to, satisfaction of the requirements of Rule 16b-3(e) under the Exchange Act. Further, the Company shall ensure that following the Effective Time no participant in the Company Equity Incentive Plans or other plans, programs or arrangements shall have any right thereunder to acquire any equity securities of the Company, the Surviving Corporation or any Subsidiary. Prior to the Effective Time, the Company shall take all actions necessary pursuant to the terms of the Company’s Employee Stock Purchase Plan (the “Company ESPP”) to (i) shorten each currently ongoing purchase and/or offering period under the Company ESPP that extends beyond the Effective Time (the “Current Offering(s)”) such that a new purchase date for each such Current Offering shall occur prior to the Effective Time and shares of Common Stock shall be purchased by the Company ESPP participants prior to the Effective Time, and (ii) preclude the commencement of any new purchase or offering period. The Company shall take all actions necessary so that the Company ESPP shall terminate immediately prior to the earlier of (A) the day preceding the Effective Time and (B) the date upon which the Company ESPP terminates by its terms.

(c) Upon the Effective Time, by virtue of the Merger and without any action on the part of the Company, Acquiror, Acquiror Sub or the holders thereof, all Common Stock and the Company Options shall no longer be outstanding and shall automatically be canceled and shall cease to exist, and each certificate (a “Certificate”) previously representing any such Common Stock and each agreement (an “Option Agreement”) previously representing any such Company Options shall thereafter represent only the right to receive the Per Share Merger Consideration or the Option Merger Consideration, as applicable. Payments made in respect of the Company Options shall be in full satisfaction of all obligations under the Company Equity Incentive Plans and the Option Agreements. If prior to the Effective Time, the Company should split or combine its common shares, or pay a dividend in common shares or other distribution in such common shares, then the Per Share Merger Consideration and Option Merger Consideration shall be appropriately adjusted to reflect such split, combination, dividend or distribution.

(d) At the Effective Time, by virtue of the Merger and without any action on the part of the Company, Acquiror, Acquiror Sub or any holder thereof, and notwithstanding any other provision hereof that may be to the contrary, all Common Stock that is owned directly by Acquiror, Acquiror Sub or the Company (or held in the Company’s treasury) shall be canceled and shall cease to exist and no cash or other consideration shall be delivered in exchange therefor.

(e) Notwithstanding any other provision hereof that may be to the contrary, any Shareholder who has not voted such shares in favor of the Merger and who has demanded or may properly demand appraisal rights in the manner provided by Section 262 of Delaware Law (“Dissenting Shares”) shall not be converted into a right to receive a portion of the Merger Consideration unless and until the Effective Time has occurred and the holder of such Dissenting Shares becomes ineligible for such appraisal rights. The holders of Dissenting Shares shall be entitled only to such rights as are granted by Section 262 of Delaware Law. Each holder of Dissenting Shares who becomes entitled to payment for such shares pursuant to Section 262 of Delaware Law shall receive payment therefor from Acquiror in accordance with Delaware Law; provided, however, that (i) if any such holder of Dissenting Shares shall have failed to establish entitlement to appraisal rights as provided in Section 262 of Delaware Law, (ii) if any such holder of Dissenting Shares shall have effectively withdrawn demand for appraisal of such shares or lost the right to appraisal and payment for shares under Section 262 of Delaware Law or (iii) if neither any holder of Dissenting Shares nor Surviving Corporation shall have filed a petition demanding a determination of the value of all Dissenting Shares within the time provided in Section 262 of Delaware Law, such holder of Dissenting Shares shall forfeit the right to appraisal of such shares and each such Dissenting Share shall be treated as if it had been, as of the Effective Time, converted into a right to receive the Per Share Merger Consideration, without interest thereon, as provided in this Section 2.3 of this Agreement. The Company shall give Acquiror prompt notice of any demands received by the Company for appraisal of any shares of Common Stock, and Acquiror shall have the right to participate in all negotiations and proceedings with respect to such demands. The Company shall not, except with the prior written consent of Acquiror, make any payment with respect to, or settle or offer to settle, any such demands, with respect to any holder of Dissenting Shares before the Effective Time.

(f) At the Effective Time, by virtue of the Merger and without any action on the part of the Company, Acquiror, Acquiror Sub or any holder thereof, each common share, par value $0.001 per share, of Acquiror Sub issued and outstanding immediately prior to the Effective Time shall be converted into one fully paid and nonassessable common share, par value $0.001 per share, of the Surviving Corporation.

(g) All cash paid in respect of the surrender for exchange of shares of Common Stock in accordance with the terms hereof shall be deemed to be in full satisfaction of all rights pertaining to such shares of Common Stock. If, after the Effective Time, Certificates are presented to the Surviving Corporation for any reason, they shall be canceled and exchanged as provided in this Article.

ARTICLE III

EXCHANGE PROCEDURES

3.1 Acquiror to Make Funds Available.

At or prior to the Effective Time, Acquiror shall deposit, or shall cause to be deposited, with a bank or trust company reasonably acceptable to the Company (the “Exchange Agent”), on a timely basis, if and when needed for the benefit of the holders of Certificates, the aggregate Total Merger Consideration in cash sufficient for the Exchange Agent to make full payment of the Per Share Merger Consideration pursuant to Section 2.3 (the “Exchange Fund”). There shall be a written agreement between Acquiror and the Exchange Agent in which the Exchange Agent expressly undertakes, on reasonably customary terms, the obligation to pay the aggregate Per Share Merger Consideration as provided herein. The Company shall have a reasonable opportunity, but in any event at least five (5) Business Days, to review and comment on the agreement with the Exchange Agent prior to it being finalized.

3.2 Exchange.

(a) As soon as practicable, but no more than three (3) Business Days, after the Effective Time, provided that Company has cooperated to make the necessary information available thereto a sufficient time in advance, the Exchange Agent shall mail to each holder of record of a Certificate or Certificates a form letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Exchange Agent) and instructions for use in effecting the surrender of the Certificates in exchange for payment of the Per Share Merger Consideration pursuant to this Agreement. Additionally, the Exchange Agent shall provide a form of the letter of transmittal to the Company prior to the Closing Date. Upon surrender of a Certificate for exchange and cancellation to the Exchange Agent, together with such letter of transmittal, duly executed, the holder (or any agent thereof) of such Certificate shall be entitled to receive promptly in exchange therefor a check or wire transfer (provided such holder shall be responsible for any wire transfer fees) payable to such holder (or any agent thereof) representing the amount of cash to which such holder shall have become entitled pursuant to the provisions of Article II hereof, and the Certificate so surrendered shall forthwith be canceled.

(b) As of the Effective Time, there shall be no transfers on the stock transfer books of the Company of the Common Stock that were issued and outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates representing such shares are presented for transfer to the Exchange Agent, they shall be canceled and exchanged for the Per Share Merger Consideration as provided in this Article III.

(c) Any portion of the Exchange Fund that remains unclaimed by the former Shareholders of the Company twelve (12) months after the Effective Time shall be returned to Acquiror. After such funds have been returned to Acquiror, any former Shareholders of the Company who have not theretofore complied with this Article III shall thereafter look only to Acquiror for payment of the Per Share Merger Consideration deliverable in respect of each share of Common Stock such Shareholders hold as determined pursuant to this Agreement, in each

case, without any interest thereon. Notwithstanding the foregoing, none of Acquiror, the Company, the Exchange Agent or any other Person shall be liable to any former holder of Common Stock for any amount properly delivered to a public official pursuant to applicable abandoned property, escheat or similar laws. Acquiror, any Affiliate of Acquiror, any Affiliated Person or the Exchange Agent will be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement or the transactions contemplated hereby to any holder of Common Stock or the Company Options such amounts as Acquiror (or any Affiliate of Acquiror or Affiliated Person) or the Exchange Agent are required to deduct and withhold with respect to the making of such payment under Delaware Law, or any applicable provision of U.S. federal, state, local or non-U.S. tax law. To the extent that such amounts are properly withheld by Acquiror (or any Affiliate of Acquiror or Affiliated Person) or the Exchange Agent and paid over to the appropriate taxing authority, such withheld amounts will be treated for all purposes of this Agreement as having been paid to the holder of the Common Stock or the Company Options in respect of whom such deduction and withholding were made by such Person.

(d) In the event any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate (whether the record holder or any agent thereof) to be lost, stolen or destroyed, and, if required by Acquiror, the posting by such Person of a bond in such amount as Acquiror or may determine is reasonably necessary as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Certificate a check representing the Per Share Merger Consideration deliverable to such holder (or any agent thereof) in respect thereof pursuant to this Agreement. If payment of the Per Share Merger Consideration is to be made to any Person other than the registered holder of the Certificate surrendered in exchange therefor, it shall be a condition of the payment or issuance thereof that the Certificate so surrendered shall be properly endorsed (or accompanied by an appropriate instrument of transfer) and otherwise in proper form for transfer, and that the Person requesting such exchange shall pay to the Exchange Agent in advance any transfer or other similar taxes required by reason of the payment of the Per Share Merger Consideration to any Person other than the registered holder of the Certificate surrendered, or required for any other reason relating to such holder or requesting Person, or shall establish to the reasonable satisfaction of Acquiror and the Exchange Agent that such tax has been paid or is not payable.

ARTICLE IV

TERMINATION

4.1 Termination.

This Agreement may be terminated at any time (except where otherwise indicated) prior to the Closing, whether before or after approval of this Agreement (unless otherwise set forth below), as follows:

(a) by mutual written consent of Acquiror and the Company;

(b) by Acquiror, (i) if there has been a breach of any covenant or agreement on the part of the Company that causes the condition provided in Section 9.2(b) not to be met

and such breach has not been cured (if curable) within ten (10) Business Days following receipt by the Company of written notice of such breach describing the extent and nature thereof in reasonable detail or (ii) if there has been any event, change, occurrence or circumstance that renders the conditions set forth in Section 9.2(a) incapable of being satisfied by October 31, 2007 (the “Outside Date”);

(c) by the Company, (i) if there has been a breach of any covenant or agreement on the part of Acquiror or Acquiror Sub that causes the condition provided in Section 9.3(b) not to be met and such breach has not been cured (if curable) within ten (10) Business Days following receipt by Acquiror of written notice of such breach describing the extent and nature thereof in reasonable detail or (ii) or there has been any event, change, occurrence or circumstance that renders the conditions set forth in Section 9.3(a) incapable of being satisfied by the Outside Date;

(d) by either Acquiror or the Company if there shall be in effect a final, unappealable Order restraining, enjoining or otherwise prohibiting the consummation of the transactions contemplated hereby; provided, however, that the party seeking to terminate this Agreement pursuant to this clause (d) shall not have initiated such proceeding or taken any action in support of such proceeding (it being agreed that the Parties shall use their commercially reasonable efforts to promptly appeal any such Order that is not unappealable and diligently pursue such appeal);

(e) by either Acquiror or the Company if the approval of the shareholders of the Company hereto required for the consummation of the Merger shall not have been obtained by reason of the failure to obtain the Requisite Shareholder Vote at a duly held Special Meeting of Shareholders or at any adjournment or postponement thereof (provided that the right to terminate this Agreement under this Section 4.1(e) shall not be available to any Party seeking termination who at the time is in breach or has failed to fulfill its obligations under Section 7.4 of this Agreement);

(f) by either Acquiror or the Company on or after the Outside Date if the Closing shall not have occurred by the close of business on such date (unless the failure to consummate the Closing is attributable to a breach of this Agreement on the part of the Party seeking to terminate this Agreement); provided, however, that the terminating party is not in material default of any of its obligations hereunder;

(g) by Acquiror if, the Board shall have (i) endorsed, approved or recommended any Acquisition Proposal in accordance with Section 7.8, other than that contemplated by this Agreement; (ii) effected a Change in Recommendation, (iii) resolved to do any of the foregoing or (iv) failed to reconfirm the Company Board Recommendation within ten (10) Business Days after Acquiror requests in writing that the Board do so;

(h) by Acquiror if (i) the Company shall have entered into a definitive agreement with respect to an Acquisition Proposal; or (ii) a tender offer or exchange offer for outstanding shares of the Common Stock is commenced (other than by Acquiror or an Affiliate of Acquiror) and the Board recommends that the Shareholders tender their shares in such tender or exchange offer or, within ten (10) Business Days after such tender or exchange offer, fails to

recommend against acceptance of such offer or takes no position with respect to the acceptance thereof or (iii) for any reason the Company fails to hold the Special Meeting by the Outside Date; or

(i) by the Company if, at any time prior to receiving the Requisite Shareholder Approval, the Board authorizes the Company, subject to complying with the terms of this Agreement in all material respects, to terminate this Agreement in order to enter into a binding, definitive agreement with respect to a Superior Proposal; provided that the Company shall have first paid to Acquiror the Company Termination Fee; and provided, further, that (A) the Company shall have provided Acquiror with written notice of its intent to terminate this Agreement pursuant to this Section 4.1(i) at least three (3) Business Days in advance of such termination, which written notice shall include the most current version of the definitive agreement and a reasonably detailed summary of any other material terms and conditions relating thereto, and (B) Acquiror does not make, within three (3) Business Days of receipt of such written notice, an offer that the Board determines, in good faith after consultation with the Company’s legal and financial advisors and taking into account all the terms and conditions of such offer (including any break-up fees, expense reimbursement provisions and conditions to consummation), would, if consummated, result in a transaction at least as favorable to the Shareholders as the transaction set forth in the Company’s written notice delivered pursuant to clause (A) above, it being understood that the Company shall not enter into any such binding, definitive agreement during such three (3) Business Day period (the Company agrees to notify Acquiror promptly if its intention to enter into any such agreement referred to in Section 4.1(i)(A) shall change at any time after giving such notification).

4.2 Procedure Upon Termination.

In the event of termination and abandonment by Acquiror or the Company, or both, pursuant to Section 4.1 hereof, written notice thereof shall forthwith be given to the other Party or Parties and this Agreement shall terminate, and the Merger shall be abandoned, without further action by Acquiror or the Company.

4.3 Effect of Termination.

Upon the termination of this Agreement in accordance with Sections 4.1 and 4.2 hereof, Acquiror and the Company shall be relieved of any further duties and obligations under this Agreement after the date of such termination; provided, that no such termination shall relieve any Party hereto from Liability for any willful breach or fraud by a Party of this Agreement; provided, further, that the obligations of the Parties set forth in Section 4.5, Articles X and XII hereof shall survive any such termination and shall be enforceable after such termination.

4.4 Frustration of Conditions.

Neither Acquiror or Acquiror Sub, on the one hand, nor the Company, on the other, may rely on the failure of any condition set forth in Section 9.1, 9.2, or 9.3 to be satisfied if such failure was caused by such Party’s failure to comply with or perform any of its covenants or obligations set forth in this Agreement.

4.5 Fees and Expenses.

(a) Except as otherwise set forth in this Section 4.5 or in Section 12.7, all expenses incurred in connection with this Agreement shall be paid by the Party incurring such expenses, whether or not the transactions contemplated hereunder are consummated.

(b) The Company agrees that, in order to compensate Acquiror for the direct and substantial damages suffered by Acquiror in the event of termination of this Agreement under certain circumstances, which damages cannot be determined with reasonable certainty, the Company shall pay to Acquiror the Company Termination Fee upon the earliest to occur of the following events:

(i) The termination of this Agreement by Acquiror pursuant to Sections 4.1(b)(i), (g) or (h);

(ii) The termination of this Agreement by Acquiror or the Company pursuant to Sections 4.1(e) and (f) if within twelve (12) months of the termination of this Agreement, the Company has consummated a transaction with respect to an Acquisition Proposal that was publicly announced or communicated to the Board or senior management and not withdrawn prior to the date of the termination; or

(iii) The termination of this Agreement by the Company pursuant to Section 4.1(i).

For purposes of this Agreement, “Company Termination Fee” means an amount equal to three and one half percent (3.5%) of the Total Merger Consideration less any Expenses actually reimbursed and paid by the Company to Acquiror under Section 4.5(c).

(c) Upon any termination of this Agreement for which a Company Termination Fee is due and payable under Section 4.5(b) (provided that neither Acquiror’s nor Acquiror Sub’s noncompliance with its obligations under this Agreement has materially contributed to the breach, failure to perform or other event or condition giving rise to such termination), the Company shall reimburse Acquiror and its Affiliates for one hundred percent (100%) of their Expenses (as defined below) in an amount not to exceed three and one half percent (3.5%) of the Total Merger Consideration. In the event this Agreement is terminated pursuant to Section 4.1(e), but a Company Termination Fee is not payable under Section 4.5(b), the Company shall reimburse Acquiror and its Affiliates for one hundred percent (100%) of their Expenses (as defined below) in an amount not to exceed Six Hundred Fifty Thousand and No/100 Dollars ($650,000). The term “Expenses” means all actual and documented out-of-pocket expenses of Acquiror and its Affiliates in connection with this Agreement and the transactions contemplated hereby, including, without limitation, fees and expenses of accountants, attorneys and financial advisors, and all costs of Acquiror and its Affiliates relating to the financing of the Merger (including, without limitation, advisory and commitment fees and reasonable fees and expenses of counsel to potential lenders).

Any written notice delivered pursuant to this Section 7.7 shall not be deemed to have cured any misrepresentation or breach of warranty that otherwise might have existed hereunder by reason of the development or information, and the Company agrees to use its commercially reasonable efforts to remedy such misrepresentation or breach. The delivery of any written notice pursuant to this Section 7.7 shall not limit or otherwise affect the remedies available hereunder to the Party receiving such notice.

(i) contact such Person and its advisors solely for the purpose of clarifying the proposal and any material terms thereof and the conditions to and likelihood of consummation, so as to determine whether the proposal for an Acquisition Proposal is reasonably likely to lead to a Superior Proposal, and

(ii) if the Board determines in good faith following consultation with the Company’s legal and financial advisors that such Acquisition Proposal is reasonably likely to lead to a Superior Proposal, the Board may:

(A) furnish non-public information with respect to the Company to the Person who made such proposal (provided that the Company (x) has previously or concurrently furnished such information to Acquiror and (y) shall furnish such information pursuant to a confidentiality agreement which is at least as favorable to the Company as the Confidentiality Agreement),

(B) disclose to its shareholders any information required to be disclosed under applicable Law,

(D) following receipt of an Acquisition Proposal that constitutes a Superior Proposal (x) terminate this Agreement pursuant to, and subject to compliance with, Section 4.1(i) or (y) take any nonappealable, final action that any court of competent jurisdiction orders the Company to take; but in each case referred to in clauses (A) through (D) only if, after complying with this Section 7.8(c), the Board determines in good faith by a majority vote, after consultation with, and after considering advice from, outside legal counsel to the Company, that such action is necessary to comply with its fiduciary duties to the Company or its shareholders under applicable Delaware Law. Nothing in this Section 7.8 or elsewhere in this Agreement shall prevent the Board from complying with Rule 14d-9 or Rule 14e-2(a) promulgated under the Exchange Act with respect to an Acquisition Proposal or from making any required disclosure to the Shareholders if, in the good faith judgment of the Board, after consultation with outside legal counsel, it determines that it is necessary to do so to comply with its obligations under applicable Law, including Rule 14d-9 promulgated under the Exchange Act or Item 1012(a) of Regulation M-A; provided, however, that neither the Company nor the Board shall be permitted to recommend pursuant to such provision an Acquisition Proposal which is not a Superior Proposal.

(e) The Board shall not take any of the actions referred to in clause (C) or (D) of Section 7.8(d)(ii) unless (i) the Company has given Acquiror at least three (3) Business Days notice, measured from the receipt of notice of such proposal or the receipt of any material change to the terms thereof, of its intent to take such action and (ii) after waiting at least such three (3) Business Day period and taking into account any amendment to this Agreement entered into or to which Acquiror irrevocably covenants to enter into and for which all internal approvals of Acquiror have been obtained since receipt of such notice, such Superior Proposal remains a Superior Proposal.

(b) After the Merger, Acquiror and Acquiror Sub will honor and perform the obligations of the Company under the contracts, plans and arrangements listed in Schedule 8.1(b) in accordance with their terms; provided, however, the restricted period contained in the non-competition provisions set forth in the employment agreement for certain officers shall be extended to a mutually agreed period not to exceed three (3) years.

Acquiror Benefit Plans.

Acquiror or one of its Affiliates will recognize all service of the Covered Employees with the Company or any of its Affiliates for purposes of eligibility to participate, vesting and, as to welfare benefit plans and vacation benefits, benefits accrual, in those employee benefit plans, within the meaning of Section 3(3) of ERISA, in which the Covered Employees are enrolled by Acquiror or one of its Affiliates immediately after the Closing Date. Acquiror, or one of its Affiliates, will also use its commercially reasonable efforts to cause, subject to the consent and cooperation of the third party insurers, (a) all pre-existing conditions and proof of insurability provisions, for all conditions that all Covered Employees and their covered dependents have as of the Closing Date (subject, also, to each Covered Employee providing, in a form reasonably acceptable to Acquiror, a certificate of creditable coverage from such medical, health or dental plans of the Company under which such Covered Employee was covered in the twelve (12) months preceding the Effective Time), and (b) all waiting periods under each plan that would otherwise be applicable to newly hired employees to be waived in the case of clause (i) or clause

(ii) with respect to Covered Employees to the same extent waived or satisfied under the Company’s Employee Plans; provided that nothing in this sentence shall limit the ability of Acquiror and its Affiliates from amending or entering into new or different employee benefit plans or arrangements provided such plans or arrangements treat the Covered Employees in a substantially similar manner as employees of Acquiror or its Affiliate, as applicable, are treated.

8.3

No Third Party Beneficiaries.

No provision of this Article VIII shall create any third party beneficiary or other rights in any Employee or Former Employee (including any beneficiary or dependent thereof) of the Company or of any of its subsidiaries in respect of continued employment (or resumed employment) with either Acquiror or any of their Affiliates and no provision of this Article VIII shall create any such rights in any such Persons in respect of any benefits that may be provided, directly or indirectly, under any Employee Plan or any plan or arrangement which may be established by Acquiror or any of its Affiliates. No provision of this Agreement shall constitute a limitation on rights to amend, modify or terminate after the Closing Date any such plans or arrangements of Acquiror or any of its Affiliates.

10.2

Indemnification and Insurance.

(a) For a period of five (5) years from and after the Effective Time (and subject to the further limitation contained herein), the Surviving Corporation shall indemnify and hold harmless, as and to the fullest extent permitted by Delaware Law and the Certificate of

Incorporation and Bylaws of the Company, as in effect on April 1, 2007, any Person who is now, or who becomes prior to the Effective Time, a director or executive officer of the Company (the “Indemnified Parties”) against any losses, claims, damages, liabilities, costs, expenses (including reasonable attorney’s fees and expenses in advance of the final disposition of any claim, suit, proceeding or investigation to each Indemnified Party to the fullest extent permitted by Delaware Law upon receipt of an undertaking to repay such advanced expenses if it is determined by a judgment of a court of competent jurisdiction that such Indemnified Party was not entitled to indemnification and such other undertakings required by applicable law), judgments, fines and amounts paid in settlement (“Damages”) in connection with any such threatened or actual claim, action, suit, proceeding or investigation to which any Indemnified Party is or may become a party by virtue of his or her service as a present or former director or executive officer of the Company and arising out of actual or alleged events, actions or omissions occurring or alleged to have occurred at or prior to the Effective Time (including, without limitation, the Merger), but only if the applicable Indemnified Party acted in good faith and in a manner such Indemnified Party reasonably believed to be in or not opposed to the best interests of the Company, and with respect to any criminal Legal Proceeding, had no reasonable cause to believe the Indemnified Party’s conduct was unlawful (an “Indemnified Matter”). In connection with any Indemnified Matter, the Indemnified Parties may retain counsel reasonably satisfactory to Acquiror; provided, however, that (i) Acquiror shall have the right to assume the defense thereof and upon such assumption Acquiror shall not be liable to any Indemnified Party for any legal expenses of counsel or any other expenses subsequently incurred by any Indemnified Party in connection with the defense thereof, except that if Acquiror elects not to assume such defense or counsel for the Indemnified Parties reasonably advises the Indemnified Parties that there are issues which raise conflicts of interest between Acquiror and the Indemnified Parties, the Indemnified Parties may retain counsel reasonably satisfactory to Acquiror, and Acquiror shall pay the reasonable fees and expenses of such counsel for the Indemnified Parties, (ii) Acquiror shall be obligated pursuant to this paragraph to pay for not more than one counsel for each Indemnified Party, (iii) Acquiror shall not be liable for any settlement effected without its prior written consent (which consent shall not be unreasonably withheld or delayed), and (iv) Acquiror shall not be obligated pursuant to this paragraph to the extent that a judgment of a court of competent jurisdiction determines that any Damages are as a result of the gross negligence or willful misconduct or result from a decision made by the Indemnified Party when the Indemnified Party had no good faith belief that he or she was acting in the best interests of the Company. Any Indemnified Party wishing to claim indemnification under this Section 10.2, upon learning of any such claim, action, suit, proceeding or investigation, shall promptly notify Acquiror thereof; provided, however, that the failure to so notify shall not affect the obligations of Acquiror under this Section 10.2 except to the extent such failure to notify materially prejudices Acquiror. Acquiror’s obligations under this Section 10.2 continue in full force and effect for a period of five (5) years from the Effective Time; provided, however, that all rights to indemnification in respect of any claim asserted or made within such period shall continue until the final disposition of such claim.

(“Tail Insurance”); provided that in no event shall Acquiror be required to expend annually in the aggregate an amount in excess of the annual premium for such Tail Insurance (the “Insurance Amount”); and provided, further, that if Acquiror is unable to maintain such policy (or such substitute policy) as a result of the preceding proviso, Acquiror shall obtain as much comparable insurance as is available for the Insurance Amount.
