As used herein, the “Effective Time” shall mean the time at which the Merger shall become effective.

Section 2.6 Effect on Capital Stock.

(a) At the Effective Time, subject to the provisions of this ARTICLE II, each share of Company Common Stock issued and outstanding immediately prior to the Effective Time (other than shares of Company Common Stock owned by Parent, Merger Sub or the Company) shall, by virtue of the Merger and without any action on the part of the holder thereof, be converted into and shall thereafter represent the right to receive (i) 0.1034 shares (as may be adjusted pursuant to this Section 2.6, the “Exchange Ratio”) of Parent Common Stock (unless the aggregate number of shares of Parent Common Stock to be issued in the Merger pursuant to this Section 2.6 and Section 2.7 would equal or exceed the Maximum Share Number, in which case the Exchange Ratio shall be reduced (the amount of such reduction, the “Exchange Ratio Reduction Number”) to the minimum extent necessary such that the number of shares of Parent Common Stock issuable in the Merger pursuant to this Section 2.6 and Section 2.7 is less than the Maximum Share Number) (the “Stock Consideration”) and (ii) $24.50 in cash1, without interest, plus, if the Exchange Ratio is adjusted pursuant to the preceding clause (i), the amount in cash, without interest, equal to the Exchange Ratio Reduction Number multiplied by the Parent Common Stock Cash Value (the “Cash Consideration”). Together with any cash in lieu of fractional shares of Parent Common Stock to be paid pursuant to Section 2.13, the Stock Consideration and Cash Consideration are collectively referred to herein as the “Merger Consideration”.

(b) From and after the Effective Time, none of the Company Common Stock converted into the Merger Consideration pursuant to this ARTICLE II shall remain outstanding and shall automatically be cancelled and retired and shall cease to exist, and each holder of a certificate previously representing any such Company Common Stock or shares of Company Common Stock that are in non-certificated book-entry form (either case being referred to in this Agreement, to the extent applicable, as a “Certificate”) shall thereafter cease to have any rights with respect to such securities, except the right to receive (i) the consideration to which such holder may be entitled pursuant to this Section 2.6, (ii) any dividends and other distributions in accordance with Section 2.9(f) and (iii) any cash to be paid in lieu of any fractional share of Parent Common Stock in accordance with Section 2.13.

(c) If at any time during the period between the date of this Agreement and the Effective Time, any change in the outstanding shares of Securities of Parent or the Company shall occur 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, the Merger Consideration and any other similarly dependent items shall be appropriately adjusted to provide the holders of Company Common Stock the same economic effect as contemplated by this Agreement prior to such event. Nothing in this Section 2.6(c) shall be construed to require or permit either Parent or the Company to take any action that is otherwise prohibited or restricted by any other provision of this Agreement.

(d) At the Effective Time, (i) all shares of Company Common Stock that are owned by Parent, Merger Sub or the Company shall, by virtue of the Merger and without any action on the part of the holder thereof, be cancelled and retired and shall cease to exist and no Securities of Parent, cash or other consideration shall be delivered in exchange therefor and (ii) each share of Company Common Stock held by any wholly owned Subsidiary of the Company or any wholly owned Subsidiary of Parent (other than Merger Sub) shall, by virtue of the Merger and

1 Assumes $7.50 per share special cash dividend has been paid.

without any action on the part of the holder thereof, be converted into such number of fully paid and nonassessable shares (or fractions thereof) of common stock of the Surviving Corporation that preserves the relative ownership interest represented by such share of Company Common Stock immediately prior to the Merger.

(e) At the Effective Time, each issued and outstanding share of capital stock of Merger Sub shall, by virtue of the Merger and without any action on the part of the holder thereof, be converted into and become one fully paid and nonassessable share of common stock of the Surviving Corporation.

Section 2.7 Treatment of Company Equity-Based Awards.

(a) Each option to purchase shares of Company Common Stock (a “Company Stock Option”) granted under any equity or equity-based compensation plan or arrangement of the Company (each, a “Company Stock Plan”), whether vested or unvested, that is outstanding and unexercised immediately prior to the Effective Time shall cease, at the Effective Time, to represent a right to acquire shares of Company Common Stock and shall be converted at the Effective Time, without any action on the part of any holder of any Company Stock Option, into an option to purchase Parent Common Stock (a “Parent Stock Option”), on the same terms and conditions as were applicable under such Company Stock Option. The number of shares of Parent Common Stock subject to each such Company Stock Option shall be equal to the number of shares of Company Common Stock subject to each such Company Stock Option multiplied by the Stock Award Exchange Ratio, rounded down to the nearest whole share of Parent Common Stock, and such Parent Stock Option shall have an exercise price per share (rounded up to the nearest cent) equal to the per share exercise price specified in such Company Stock Option divided by the Stock Award Exchange Ratio; provided, that, in the case of any Company Stock Option to which Section 421 of the Code applies as of the Effective Time by reason of its qualification under Section 422 of the Code, the exercise price, the number of shares of Parent Common Stock subject to such option and the terms and conditions of exercise of such option shall be determined in a manner consistent with the requirements of Section 424(a) of the Code.

(b) At the Effective Time, each Equity Right consisting of, based on or relating to shares of Company Common Stock granted under a Company Stock Plan, other than the Company Stock Options (each, a “Company Stock-Based Award”), which is outstanding immediately prior to the Effective Time, whether vested or unvested, shall cease, at the Effective Time, to represent an Equity Right with respect to shares of Company Common Stock and shall be converted without any action on the part of any holder of an Equity Right, at the Effective Time, into an Equity Right consisting of, based on or relating to shares of Parent Common Stock (each, a “Parent Stock-Based Award”), on the same terms and conditions as were applicable under the Company Stock-Based Awards. The number of shares of Parent Common Stock subject to each such Parent Stock-Based Award shall be equal to the number of shares of Company Common Stock subject to the Company Stock-Based Award multiplied by the Stock Award Exchange Ratio, rounded down to the nearest whole share of Parent Common Stock and, if applicable, such Parent Stock-Based Award shall have an exercise price per share (rounded up to the nearest cent) equal to the per share exercise price specified in the Company Stock-Based Award divided by the Stock Award Exchange Ratio.

(c) As soon as practicable after the Effective Time, Parent shall deliver to the holders of Company Stock Options and Company Stock-Based Awards any required notices setting forth such holders’ rights pursuant to the relevant Company Stock Plans and award documents and stating that such Company Stock Options and Company Stock-Based Awards have been assumed by Parent and shall continue in effect on the same terms and conditions (subject to the adjustments required by this Section 2.7 after giving effect to the Merger and the terms of the relevant Company Stock Plans).

(d) Prior to the Effective Time, the Company shall take all necessary action to permit the adjustment of Company Stock Options and Company Stock-Based Awards under this Section 2.7. Parent shall reserve for future issuance a number of shares of Parent Common Stock at least equal to the number of shares of Parent Common Stock that will be subject to Parent Stock Options and Parent Stock-Based Awards as a result of the actions contemplated by this Section 2.7.

Section 2.8 Appraisal or Dissenters’ Rights. No appraisal or dissenters’ rights shall be available to holders of Company Common Stock with respect to the Merger or the other transactions contemplated hereby.

Section 2.9 Exchange of Shares.

(a) Prior to the Effective Time, Parent shall appoint an exchange agent (the “Exchange Agent”) for the purpose of exchanging Certificates for the Merger Consideration. As soon as reasonably practicable after the Effective Time, Parent will cause the Exchange Agent to send, to each holder of record of shares of Company Common Stock as of the Effective Time, whose shares of Company Common Stock were converted into the right to receive the Merger Consideration pursuant to Section 2.6, a letter of transmittal (which shall specify that the delivery shall be effected, and risk of loss and title shall pass, only upon proper delivery of the Certificates to the Exchange Agent), including instructions for use in effecting the surrender of Certificates to the Exchange Agent in exchange for the Merger Consideration. Promptly after the Effective Time, Parent shall cause to be deposited with the Exchange Agent (i) the number of shares of Parent Common Stock (which shall be in non-certificated book-entry form) payable as Stock Consideration upon due surrender of the Certificates pursuant to the provisions of this ARTICLE II and (ii) cash in U.S. dollars sufficient to pay the aggregate Cash Consideration and cash in lieu of fractional shares payable upon due surrender of the Certificates pursuant to the provisions of this ARTICLE II. Following the Effective Time, Parent agrees to make available to the Exchange Agent, from time to time as needed, cash in U.S. dollars sufficient to pay any dividends and other distributions pursuant to Section 2.9(f). All cash and book-entry shares representing Parent Common Stock deposited with the Exchange Agent shall be referred to in this Agreement as the “Exchange Fund.” The Exchange Agent shall, pursuant to irrevocable instructions, deliver the Merger Consideration contemplated to be issued pursuant to Section 2.6 and Section 2.13 out of the Exchange Fund. The Exchange Fund shall not be used for any other purpose. The Exchange Agent shall invest any cash included in the Exchange Fund as directed by Parent. Any interest and other income resulting from such investments shall be the property of, and paid to, Parent.

(b) Each holder of shares of Company Common Stock that have been converted into the right to receive the Merger Consideration, upon surrender to the Exchange Agent

of a Certificate, together with a properly completed letter of transmittal, duly executed and completed in accordance with the instructions thereto, and such other documents as may reasonably be required by Parent or the Exchange Agent, will be entitled to receive in exchange therefor (i) one or more shares of Parent Common Stock (which shall be in non-certificated book-entry form unless a physical certificate is requested) representing, in the aggregate, the whole number of shares of Parent Common Stock that such holder has the right to receive, (ii) a check in the amount that such holder has the right to receive pursuant to the provisions of this ARTICLE II, including the Cash Consideration, cash payable in lieu of fractional shares pursuant to Section 2.13 and dividends and other distributions payable pursuant to Section 2.9(f) (less any required Tax withholding). The Merger Consideration shall be paid as promptly as practicable after receipt by the Exchange Agent of the Certificate and letter of transmittal in accordance with the foregoing. No interest shall be paid or accrued on any Merger Consideration, cash in lieu of fractional shares or on any unpaid dividends and distributions payable to holders of Certificates. Until so surrendered, each such Certificate shall, after the Effective Time, represent for all purposes only the right to receive such Merger Consideration.

(c) If any portion of the Merger Consideration is to be registered in the name of or paid to a Person other than the Person in whose name the applicable surrendered Certificate is registered, it shall be a condition thereof that the surrendered Certificate shall be properly endorsed or otherwise be in proper form for transfer and that the Person requesting such delivery of the Merger Consideration shall pay to the Exchange Agent any required transfer or other similar Taxes or establish to the satisfaction of the Exchange Agent that such Tax has been paid or is not payable.

(d) After the Effective Time, there shall be no further registration of transfers of shares of Company Common Stock. From and after the Effective Time, the holders of Certificates representing shares of Company Common Stock outstanding immediately prior to the Effective Time shall cease to have any rights with respect to such shares of Company Common Stock except as otherwise provided in this Agreement or by applicable Law. If, after the Effective Time, Certificates are presented to the Exchange Agent or Parent, they shall be cancelled and exchanged for the consideration provided for, and in accordance with the procedures set forth, in this ARTICLE II.

(e) Any portion of the Exchange Fund that remains unclaimed by the holders of shares of Company Common Stock one (1) year after the Effective Time shall be returned to Parent, upon demand, and any such holder who has not exchanged his or her shares of Company Common Stock for the Merger Consideration in accordance with this Section 2.9 prior to that time shall thereafter look only to Parent for delivery of the Merger Consideration in respect of such holder’s shares of Company Common Stock. Notwithstanding the foregoing, neither Parent, Merger Sub nor the Company shall be liable to any holder of shares of Company Common Stock for any Merger Consideration delivered to a public official pursuant to applicable abandoned property Laws. Any Merger Consideration remaining unclaimed by holders of shares of Company Common Stock immediately prior to such time as such amounts would otherwise escheat to or become property of any Governmental Entity shall, to the extent permitted by applicable Law, become the property of Parent free and clear of any claims or interest of any Person previously entitled thereto.

(f) No dividends or other distributions with respect to shares of Parent Common Stock issued in the Merger shall be paid to the holder of any unsurrendered Certificates until such Certificates are surrendered as provided in this Section 2.9. Following such surrender, subject to the effect of escheat, Tax or other applicable Law, there shall be paid, without interest, to the record holder of the shares of Parent Common Stock issued in exchange therefor (i) at the time of such surrender, all dividends and other distributions payable in respect of such shares of Parent Common Stock with a record date after the Effective Time and a payment date on or prior to the date of such surrender and not previously paid and (ii) at the appropriate payment date, the dividends or other distributions payable with respect to such shares of Parent Common Stock with a record date after the Effective Time but with a payment date subsequent to such surrender. For purposes of dividends or other distributions in respect of shares of Parent Common Stock, all shares of Parent Common Stock to be issued pursuant to the Merger shall be entitled to dividends pursuant to the immediately preceding sentence as if issued and outstanding as of the Effective Time.

Section 2.10 Lost, Stolen or Destroyed Certificates. If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if required by 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 Exchange Agent will issue in exchange for such lost, stolen or destroyed Certificate the Merger Consideration to be paid in respect of the shares of Company Common Stock represented by such Certificate as contemplated by this ARTICLE II.

Section 2.11 Withholding Rights. Each of Parent, Merger Sub and the Surviving Corporation shall be entitled to deduct and withhold, or cause the Exchange Agent to deduct and withhold, from the consideration otherwise payable to any Person pursuant to this Agreement such amounts as it is required to deduct and withhold with respect to the making of such payment under the Code or any provision of state, local or foreign Tax law. To the extent that amounts are so deducted or withheld and paid over to the applicable Governmental Entity or Taxing Authority, such deducted or withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of shares of Company Common Stock in respect of which such deduction and withholding was made.

Section 2.12 Further Assurances. After the Effective Time, the officers and directors of the Surviving Corporation will be authorized to execute and deliver, in the name and on behalf of the Company, any deeds, bills of sale, assignments or assurances and to take and do, in the name and on behalf of the Company, 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 acquired or to be acquired by the Surviving Corporation as a result of, or in connection with, the Merger.

Section 2.13 No Fractional Shares.

(a) No certificates or scrip representing fractional shares of Parent Common Stock shall be issued upon the surrender for exchange of Certificates (or effective affidavits of loss in lieu thereof) to the Exchange Agent, no dividends or other distributions of

Parent shall relate to such fractional share interests and such fractional share interests shall not entitle the owner thereof to vote or to any rights of a stockholder of Parent.

(b) In lieu of such fractional share interests, Parent shall pay to each holder of a Certificate an amount in cash equal to the product obtained by multiplying (i) the fractional share interest to which such holder (after taking into account all shares of Company Common Stock formerly represented by all Certificates surrendered by such holder) would otherwise be entitled by (ii) the average closing sales price, rounded to four decimal points, of shares of Parent Common Stock on the NYSE (as reported in the Wall Street Journal, New York City edition) for the period of the ten consecutive trading days ending on the second full trading day prior to the Effective Time (the “Parent Common Stock Cash Value”).

To the extent not prohibited by applicable Law, the Company shall use its reasonable best efforts to furnish to Parent all information required for any application or other filings, consents, approvals, permits or authorizations to be made pursuant to any applicable Law in connection with the transactions contemplated by this Agreement. The Company shall give Parent reasonable prior notice of any communication with, and any proposed understanding, undertaking or agreement with, any Governmental Entity regarding any such filings or any such transaction. The Company shall not independently participate in any meeting, or engage in any substantive conversation, with any Governmental Entity in respect of any such filings, investigation or other inquiry without giving Parent prior notice of the meeting or conversation and, unless prohibited by any such Governmental Entity, the opportunity to attend or participate.

In connection therewith and subject to Section 6.4(a), if any proceeding is instituted (or threatened to be instituted) challenging any transaction contemplated by this Agreement as inconsistent with or violative of any Antitrust Law, each of Parent and the Company shall (by negotiation, litigation or otherwise) cooperate and use its reasonable best efforts vigorously to contest and resist any such action or proceeding, including any administrative or judicial action, and to have vacated, lifted, reversed or overturned any Order whether temporary, preliminary or permanent, that is in effect and that prohibits, prevents, delays or restricts consummation of the transactions contemplated by this Agreement, unless Parent determines, in its sole discretion, that litigation is not in its best interests. Notwithstanding the foregoing or any other provision of this Agreement, nothing in this Section 6.4(b) shall limit the right of a Party to terminate this Agreement pursuant to Section 8.1, so long as such Party has until that time complied in all material respects with its obligations under this Section 6.4.

(c) Notwithstanding anything to the contrary in this Agreement, nothing in this Agreement shall be deemed to require Parent or any of its Subsidiaries to agree to or take any action that would result in any Burdensome Condition. None of the Company or any Company Subsidiary shall agree to or take any action that would result in any Burdensome Condition without the prior written consent of Parent. If, but only if, directed by Parent, the Company shall agree to or take any action that would result in any Burdensome Condition if such Burdensome Condition is conditioned on the consummation of the Merger. For purposes of this Agreement, a “Burdensome Condition” shall mean making proposals, executing or carrying out agreements (including consent decrees or consent orders) or submitting to Laws (i) providing for the license, sale or other disposition or holding separate (through the establishment of trust or otherwise) of any assets or categories of assets of Parent, the Company or their respective Subsidiaries or the holding separate of the capital stock of a Company Subsidiary or (ii) imposing or seeking to impose any limitation on the ability of Parent, the Company or any of their respective Subsidiaries to conduct their respective businesses (including, with respect to, market practices and structure) or own such assets or to acquire, hold or exercise full rights of ownership of the business of the Company, the Company Subsidiaries, Parent or the Parent Subsidiaries.

Section 6.5 Acquisition Proposals.

(a) Notwithstanding anything to the contrary contained in this Agreement, during the period beginning on the date of this Agreement and continuing until 11:59 p.m., New York City Time, on the 30th calendar day thereafter (the “Go-Shop End Date”), the Company and its Representatives shall have the right to: (i) initiate, solicit, facilitate and encourage inquiries relating to and the making of proposals that constitute Takeover Proposals, including by way of providing access to non-public information to a Person in connection with a Takeover Proposal pursuant to and in accordance with an executed confidentiality agreement containing customary terms and conditions, provided that such confidentiality agreement shall not contain any provisions that would prevent the Company from complying with its obligation to provide the required disclosure to Parent pursuant to Section 6.5(c), and provided further that all such information provided to such Person has previously been provided to Parent or is provided to Parent prior to or substantially concurrently with the time it is provided to such Person; and (ii) continue or otherwise participate in discussions or negotiations with respect to Takeover Proposals.

(b) During the period from and after the Go-Shop End Date and continuing until the Effective Time or the date, if any, on which this Agreement is earlier terminated pursuant to Section 8.1, the Company shall not, nor shall it authorize or permit any of its Subsidiaries to, and it shall cause its and its Subsidiaries’ respective Representatives not to, directly or indirectly: (i) initiate or solicit or facilitate or encourage any inquiry or the making of any proposal that constitutes a Takeover Proposal or (ii) continue or otherwise participate in any discussions or negotiations regarding, furnish to any Person any information or data or access to its properties with respect to, or otherwise cooperate with or take any other action to facilitate any proposal that constitutes any Takeover Proposal. Following the Go-Shop End Date, the Company shall subject to the immediately following sentence, immediately cease and cause to be terminated any existing activities, discussions or negotiations with any Persons or their Representatives with respect to any Takeover Proposal and shall request the prompt return of any confidential information previously furnished to such Persons in connection therewith. Notwithstanding the foregoing, after the Go-Shop End Date and prior to the Company Stockholders Meeting, the Company and its Representatives, in response to a bona fide written Takeover Proposal that was made after the date of this Agreement and did not result from a breach of this Agreement and that (1) constitutes a Superior Proposal or (2) the Board of Directors of the Company reasonably determines in good faith (after consultation with outside counsel and a financial advisor of nationally recognized reputation) would reasonably be expected to result in a Superior Proposal, shall be permitted to: (A) provide access to non-public information to the Person making such Takeover Proposal pursuant to and in accordance with an executed confidentiality agreement containing customary terms and conditions, provided that such confidentiality agreement shall not contain any provisions that would prevent the Company from complying with its obligation to provide the required disclosure to Parent pursuant to Section 6.5(c), and provided further that all such information provided to such Person has previously been provided to Parent or is provided to Parent prior to or substantially concurrently with the time it is provided to such Person; and (B) participate in discussions or negotiations with respect to such Takeover Proposal with the Person making such Takeover Proposal. Any violation of the restrictions set forth in this Section 6.5, including by any Representative of the Company or any of its Subsidiaries, shall be deemed to be a material breach of this Agreement by the Company.

(c) From and after the date of this Agreement, as promptly as practicable after the receipt, directly or indirectly, by the Company of any Takeover Proposal or any inquiry with respect to, or that could reasonably be expected to lead to, any Takeover Proposal, and in any case within twenty-four (24) hours after the receipt thereof, the Company shall provide oral and written notice to Parent of (i) such Takeover Proposal or inquiry, (ii) the identity of the Person making any such Takeover Proposal or inquiry and (iii) the material terms and conditions of any such Takeover Proposal or inquiry (including a copy of any such written Takeover Proposal and any amendments or modifications thereto).

(d) Except as permitted by this Section 6.3(d), neither the Board of Directors of the Company nor any committee thereof shall (i) approve, endorse or recommend, or resolve to or publicly propose to approve, endorse or recommend, any Takeover Proposal or (ii) adopt or recommend, or publicly propose to adopt or recommend, or allow the Company or any of its Subsidiaries to execute or enter into, any letter of intent, memorandum of understanding, merger agreement or other agreement, arrangement or understanding contemplating or otherwise in connection with, or that is intended to or would reasonably be expected to lead to, any Takeover Proposal (other than a confidentiality agreement permitted pursuant to Section 6.5(a) or Section 6.5(b)). Notwithstanding the foregoing, at any time prior to the Company Stockholders Meeting and subject to Section 6.5(c), the Board of Directors of the Company may in response to a Superior Proposal that was made after the date of this Agreement and did not result from a breach of this Agreement, cause the Company to terminate this Agreement and concurrently with such termination enter into a definitive agreement with respect to such Superior Proposal; provided, however, that the Company shall not be entitled to exercise its right to terminate this Agreement pursuant hereto unless (i) the Board of Directors of the Company shall have first provided prior written notice (a “Notice of Superior Proposal”) to Parent advising Parent that the Board of Directors of the Company intends to take such action and specifying the terms and conditions of the Superior Proposal that is the basis of the proposed action by the Board of Directors (including a copy of any such written Superior Proposal) and (ii) Parent does not make, within three (3) Business Days after receipt of such Notice of Superior Proposal (it being understood and agreed that any amendment to the financial terms or any other material term of such Superior Proposal shall require a new Notice of Superior Proposal and a new three (3) Business Day period), a proposal that the Board of Directors of the Company reasonably determines in good faith (after consultation with outside counsel and a financial advisor of nationally recognized reputation) is at least as favorable to the stockholders of the Company as such Superior Proposal. The Company agrees that, during the three (3) Business Day period after Parent’s receipt of a Notice of Superior Proposal, the Company and its Representatives shall negotiate in good faith with Parent and its Representatives regarding any revisions to the terms of this Agreement proposed by Parent.

(e) Nothing contained in this Section 6.5 shall prohibit the Company from complying with Rule 14d-9 and Rule 14e-2 promulgated under the Exchange Act in respect of any Takeover Proposal, provided, however, that neither the Board of Directors of the Company nor any committee thereof shall (i) take, or agree or resolve to take any action prohibited by Section 6.5(b) or Section 6.5(d) or (ii), except as expressly permitted by Section 6.2, effect a Change in Company Recommendation. The Company shall provide Parent with a copy of the text of any disclosure

proposed to be made in order to so comply at the earliest practicable time in advance of such disclosure.

Section 6.6 Employee Matters.

(a) For a period of not less than one year following the Closing Date, the Surviving Corporation shall cause each individual who is employed by the Company and any Company Subsidiary immediately before the Effective Time (each, a “Continuing Employee”) to be provided with employee benefits that are substantially comparable in the aggregate to those provided to such persons immediately prior to the Effective Time, provided that any such employee benefits shall only be required to be provided to the extent substantially comparable benefits are provided to similarly situated employees of Parent or its Subsidiaries as in effect at the Effective Time. Except to the extent necessary to avoid the duplication of benefits, the Surviving Corporation shall recognize the service of each Continuing Employee prior to the Effective Time as if such service had been performed with Parent or its Affiliates (i) for all purposes under the Company Benefit Plans maintained by the Surviving Corporation or its Affiliates after the Effective Time (to the extent such plans, programs, or agreements are provided to Continuing Employees), (ii) for purposes of eligibility and vesting under any employee benefit plans and programs of the Surviving Corporation or its ERISA Affiliates other than the Company Benefit Plans (the “Surviving Corporation Plans”) in which the Continuing Employee participates after the Effective Time and (iii) for benefit accrual purposes under any Surviving Corporation Plan that is a vacation or severance plan in which the Continuing Employee participates after the Effective Time.

(b) With respect to any welfare plan maintained by the Surviving Corporation or its Affiliates in which Continuing Employees are eligible to participate after the Effective Time, the Surviving Corporation and its Affiliates shall use reasonable best efforts to (i) waive all limitations as to preexisting conditions and exclusions with respect to participation and coverage requirements applicable to such employees to the extent such conditions and exclusions were satisfied or did not apply to such employees under the welfare plans maintained by the Company or its Affiliates prior to the Effective Time and (ii) provide each Continuing Employee with credit for any co-payments and deductibles paid prior to the Effective Time in satisfying any analogous deductible or out-of-pocket requirements to the extent applicable under any such plan.

The obligations of the Surviving Corporation under this Section 6.8 shall not be terminated or modified in such a manner as to adversely affect any indemnitee to whom this Section 6.8 applies without the consent of such affected indemnitee (it being expressly agreed that the indemnitees to whom this Section 6.8 applies shall be third party beneficiaries of this Section 6.8).

The Company shall give Parent the opportunity to participate in, subject to a customary joint defense agreement, but not control the defense or settlement of any such litigation, shall give due consideration to Parent’s advice with respect to such litigation and shall not settle any such litigation without the prior written consent of Parent (not to be unreasonably withheld or delayed).

The Company hereby consents to the use of its and the Company Subsidiaries’ logos as may be reasonably necessary in connection with the Financing.

(c) In the event that the Commitment Letter is amended, replaced, supplemented or otherwise modified, including as a result of obtaining alternative financing in accordance with Section 6.18(a), or if Parent substitutes other debt or equity financing for all or a portion of the Financing, each of Parent and the Company shall comply with its covenants set forth in Section 6.18(a) and Section 6.18(b) and with respect to the Commitment Letter as so amended, replaced, supplemented or otherwise modified and with respect to such other debt or equity financing to the same extent that Parent and the Company would have been obligated to comply with respect to the Financing.

(i) if Parent or Merger Sub shall have breached or failed to perform any of its representations, warranties or covenants contained in this Agreement, which breach or failure to perform (A) is incapable of being cured by Parent or Merger Sub prior to the Walk-Away Date or is not cured by the earlier of (x) thirty (30) Business Days following written notice to Parent or Merger Sub by the Company of such breach or (y) the Walk-Away Date and (B) would result in a failure of any condition set forth in Section 7.3(a) or Section 7.3(b); or

(ii) in accordance with the terms and subject to the conditions of Section 6.5(d).

Section 8.2 Effect of Termination.

(a) In the event of any termination of this Agreement as provided in Section 8.1, the obligations of the Parties hereunder shall terminate and there shall be no liability on the part of any Party hereto with respect thereto, except for the provisions of this Section 8.2 and ARTICLE IX, each of which shall remain in full force and effect; provided, however, that no Party hereto shall be relieved or released from any liability or damages arising from a willful breach of any provision of this Agreement.

(b) In the event that:

(i) this Agreement is terminated pursuant to Section 8.1(c)(ii), Section 8.1(c)(iii) or Section 8.1(d)(ii), then the Company shall (1) pay to Parent the amount of $150 million (the “Termination Fee”) and (2) reimburse Parent

for all out-of-pocket expenses (including, all fees and expenses of counsel, accountants, investment bankers, experts and consultants to Parent and its Affiliates and all fees and expenses incurred in connection with the Financing) incurred by Parent or on its behalf in connection with or related to Parent’s proposals for a business combination with the Company, including in connection with this Agreement and the transactions contemplated hereby, in an amount up to $[·] (the “Parent Expenses”). The Company shall pay such Termination Fee and such Parent Expenses by wire transfer of immediately available funds by the second (2nd) Business Day following such termination in the case of the termination of this Agreement pursuant to Section 8.1(c)(ii) or Section 8.1(c)(iii), or concurrently with such termination in the case of the termination of this Agreement pursuant to Section 8.1(d)(ii); or

(ii) this Agreement is terminated pursuant to Section 8.1(b)(i), Section 8.1(b)(iii) or Section 8.1(c)(i) and (x) (1) Parent shall have been entitled to terminate pursuant to Section 8.1(c)(ii) or (2) at any time after the date of this Agreement and prior to the date of termination, a Takeover Proposal shall have been publicly announced or otherwise communicated to the Board of Directors of the Company (or any Person shall have publicly announced or communicated an intention, whether or not conditional, to make a Takeover Proposal) and (y) within eighteen (18) months after the date of such termination, the Company enters into a definitive agreement to consummate, or consummates, the transactions contemplated by any Takeover Proposal, then the Company shall pay to Parent, by wire transfer of immediately available funds, an amount equal to the Termination Fee plus the Parent Expenses by the second (2nd) Business Day following the earlier of the date the Company enters into a definitive agreement or consummates such transaction; provided, that, for purposes of this Section 8.2(b)(ii), the term “Takeover Proposal” shall have the meaning ascribed thereto in Section 1.1, except that all references to fifteen percent (15%) shall be changed to thirty percent (30%).

(c) The Company agrees that the agreements contained in Section 8.2(b) are an integral part of the transaction contemplated by this Agreement, and that, without these agreements, Parent would not enter into this Agreement; accordingly, if the Company fails promptly to pay any amounts due under Section 8.2(b) and, in order to obtain such payment, Parent commences a suit that results in a judgment against the Company for such amounts, the Company shall pay interest on such amounts from the date payment of such amounts was due to the date of actual payment at the prime rate of the Bank of New York in effect on the date such payment was due, together with the costs and expenses of Parent (including reasonable legal fees and expenses) in connection with such suit.

Section 9.3 Interpretation. When a reference is made in this Agreement to Sections, Exhibits or Schedules, such reference shall be to a Section of or Exhibit or Schedule to this Agreement unless otherwise indicated. The table of contents and headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement. Whenever the words “include,” “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation.” The words describing the singular number shall include the plural and vice versa and words denoting any gender shall include all genders. The Parties have participated jointly in the negotiation and drafting of this Agreement. In the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the Parties and no presumption or burden of proof shall arise favoring or disfavoring any Party by virtue of the authorship of any provisions of this Agreement.

Section 9.4 Counterparts; Effectiveness. This Agreement may be executed in two or more counterparts, each of which shall be deemed to be an original but all of which shall constitute one and the same instrument. This Agreement shall become effective when each Party hereto shall have received counterparts thereof signed and delivered (by telecopy or otherwise) by the other Parties hereto.

Section 9.5 Entire Agreement; Third Party Beneficiaries.

(a) This Agreement (including the Exhibits and the Parties’ disclosure letters hereto) constitute the entire agreement, and supersede all prior agreements and understandings, both written and oral, between the Parties with respect to the subject matter hereof and thereof.

(b) This Agreement shall be binding upon and inure solely to the benefit of each Party hereto, and nothing in this Agreement, express or implied, is intended to or shall confer upon any Person not a Party to this Agreement any rights, benefits or remedies of any nature whatsoever, other than Section 6.8 (which is intended to be for the benefit of the Persons covered thereby and may be enforced by such Persons) and Section 9.10 (which shall be enforceable by any Financing Source).

Section 9.6 Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any law or public policy, all other terms and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner

materially adverse to any Party. Notwithstanding the foregoing, upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, 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 are consummated as originally contemplated to the greatest extent possible.

Section 9.7 Assignment. Neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned by any of the Parties, in whole or in part (whether by operation of Law or otherwise), without the prior written consent of the other Parties, and any attempt to make any such assignment without such consent shall be null and void. Subject to the preceding sentence, this Agreement will be binding upon, inure to the benefit of and be enforceable by the Parties and their respective successors and assigns.

Section 9.8 Amendment. This Agreement may be amended by the Parties at any time before or after approval of the matters presented in connection with the Merger by the stockholders of the Company or the stockholders of Parent, but, after such approval, no amendment shall be made which by Law requires further approval by such stockholders without such further approval. This Agreement may not be amended except by an instrument in writing signed on behalf of each of the Parties.

Section 9.9 Extension; Waiver. At any time prior to the Effective Time, the Parties may, to the extent legally allowed, (a) extend the time for the performance of any of the obligations or other acts of the other Parties, (b) waive any inaccuracies in the representations and warranties contained herein or in any document delivered pursuant hereto and (c) waive compliance with any of the agreements or conditions contained herein. Any agreement on the part of a Party hereto to any such extension or waiver shall be valid only if set forth in a written instrument signed on behalf of such Party. The failure of any Party to this Agreement to assert any of its rights under this Agreement or otherwise shall not constitute a waiver of those rights.

Section 9.10 GOVERNING LAW AND VENUE; WAIVER OF JURY TRIAL.

(a) THIS AGREEMENT SHALL BE DEEMED TO BE MADE IN AND IN ALL RESPECTS SHALL BE INTERPRETED, CONSTRUED AND GOVERNED BY AND IN ACCORDANCE WITH THE LAW OF THE STATE OF NEW YORK WITHOUT REGARD TO ITS RULES OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY (OTHER THAN WITH RESPECT TO MATTERS GOVERNED BY THE MGCL, WITH RESPECT TO WHICH SUCH LAW SHALL APPLY). The Parties hereby irrevocably submit to the exclusive jurisdiction of the federal and New York State courts located in the City of New York, Borough of Manhattan (and appellate courts thereof) in respect of all matters arising out of or relating to this Agreement, the interpretation and enforcement of the provisions of this Agreement, and of the documents referred to in this Agreement, and in respect of the transactions contemplated hereby, and hereby waive, and agree not to assert, as a defense in any action, suit or proceeding for the interpretation or enforcement hereof or of any such document, that it is not subject thereto or that such action, suit or proceeding may not be brought or is not maintainable in said courts or that the venue thereof may not be appropriate or that this Agreement or any such document may not be enforced in or by such courts, and the Parties hereto irrevocably agree that all claims with respect to

such action or proceeding shall be heard and determined exclusively in such courts. The Company hereby agrees that it will not bring or support any action, cause of action, claim, cross-claim or third-party claim of any kind or description, whether in law or in equity, whether in contract or in tort or otherwise, against any Financing Source in any way relating to this Agreement or any of the transactions contemplated by this Agreement, including but not limited to any dispute arising out of or relating in any way to the Commitment Letter or the performance thereof, in any forum other than the federal and New York State courts located in the City of New York, Borough of Manhattan (and appellate courts thereof). The Parties hereby consent to and grant the federal and New York State courts located in the City of New York, Borough of Manhattan (and appellate courts thereof) jurisdiction over the person of such Parties solely for such purpose and over the subject matter of such dispute and agree that mailing of process or other papers in connection with any such action or proceeding in the manner provided in Section 9.2 or in such other manner as may be permitted by law shall be valid and sufficient service thereof.

(b) EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH SUCH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (i) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER, (ii) EACH PARTY UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (iii) EACH PARTY MAKES THIS WAIVER VOLUNTARILY AND (iv) EACH PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS Section 9.10(b).

Section 9.11 Enforcement. The Parties hereto agree that irreparable damage would occur in the event that any provision of this Agreement was not performed in accordance with its specific terms or was 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 hereof in any court of competent jurisdiction, this being in addition to any other remedy to which they are entitled at law or in equity.
