ARTICLE IV

Effect of the Merger on Capital Stock;

Exchange of Eligible Shares

4.1 Effect of the Merger on Capital Stock.

At the Effective Time, by virtue of the Merger and without any action on the part of any holder of any capital stock of the Company or on the part of the sole stockholder of Merger Sub:

(a) Merger Consideration. Other than (i) the Company Shares owned directly by the Company as treasury stock or otherwise owned by the Company, Parent, Merger Sub or any other direct or indirect wholly owned Subsidiary of Parent and, in each case, not held on behalf of third parties (such shares, the “Excluded Shares”), and (ii) Dissenting Shares (which shall be treated as provided in Section 4.2(f)), each Company Share that is issued and outstanding immediately prior to the Effective Time (such shares, the “Eligible Shares”) shall be automatically converted into the right to receive, subject to Sections 4.2(h) (Fractional Shares) and 4.4 (Adjustments to Prevent Dilution), 0.8190 (the “Exchange Ratio”) newly issued Parent Shares (such consideration, the “Merger Consideration”). From and after the Effective Time, subject to Section 4.4, all of such Company Shares shall cease to be outstanding, shall be cancelled and shall cease to exist, and each certificate formerly representing any of the Eligible Shares (each, a “Certificate”) shall thereafter represent only the right to receive, as applicable, the Merger Consideration, including cash in lieu of any fractional Parent Shares which such Certificate has been converted into the right to receive, if any, pursuant to this Section 4.1 and Section 4.2(h) (the

-5-

“Fractional Share Consideration”), together with the amounts, if any, payable pursuant to Section 4.2(i), in each case without interest.

(b) Treatment of Excluded Shares. Each Excluded Share shall automatically be cancelled without payment of any consideration therefor and shall cease to exist.

(c) Merger Sub. Each share of common stock, par value $0.001 per share, of Merger Sub issued and outstanding immediately prior to the Effective Time shall be converted into one share of common stock, par value $0.001 per share, of the Surviving Corporation.

4.2 Exchange of Eligible Shares and Delivery of Merger Consideration.

(a) Deposit of Merger Consideration and Exchange Agent.

(i) At the Effective Time, Parent shall deposit, or cause to be deposited, with an exchange agent selected by Parent and reasonably acceptable to the Company (the “Exchange Agent”), a sufficient number of Parent Shares (whether represented in certificated or non-certificated direct registration form) to be issued as Merger Consideration pursuant to Section 4.1; and if and when necessary, Parent shall deposit, or cause to be deposited, with the Exchange Agent an amount in cash in immediately available funds sufficient to make payments of (x) Fractional Share Consideration, if any, and (y) dividends or distributions pursuant to Section 4.2(i), if any, in each case, in respect of the Eligible Shares (the Parent Shares and cash deposited with the Exchange Agent in accordance with the foregoing being hereinafter referred to as the “Exchange Fund”).

(ii) The agreement pursuant to which Parent shall appoint the Exchange Agent (the “Exchange Agent Agreement”) shall be in form and substance reasonably acceptable to the Company. Pursuant to the Exchange Agent Agreement, among other things, the Exchange Agent shall (A) act as the exchange agent for the issuance or payment, as applicable, and delivery of the Merger Consideration and Fractional Share Consideration, if any, and dividends or distributions pursuant to Section 4.2(i), if any, and (B) invest any cash portion of the Exchange Fund, if and as directed by Parent; provided that (1) such investments shall be in obligations of or guaranteed by the United States of America or any agency or instrumentality thereof and backed by the full faith and credit of the United States of America, in commercial paper obligations rated A-1 or P-1 or better by Moody’s Investors Service, Inc. or Standard & Poor’s Corporation, respectively, or in certificates of deposit, bank repurchase agreements or banker’s acceptances of commercial banks with capital exceeding $1,000,000,000 (based on the most recent financial statements of such bank that are then publicly available) and, in any such case, no instrument or investment shall have a maturity exceeding three (3) months and (2) to the extent that there are losses with respect to such investments, or the cash portion of the Exchange Fund diminishes for other reasons below the level required to make prompt cash payment of the Fractional Share Consideration or any dividends or distributions payable pursuant to Section 4.2(i), Parent shall promptly replace or restore or cause the replacement or restoration of the cash in the Exchange Fund lost through such investments or other events so as to ensure that the Exchange Fund is at all times maintained at a level sufficient to make such cash payments. Subject to the terms of the Exchange Agent Agreement, any interest and other income resulting from such investment (if any) shall become a part of the Exchange Fund, and any amounts (if any) in excess of the amounts

-6-

payable under Section 4.1 shall, subject to Section 4.2(d), be promptly returned to Parent or the Surviving Corporation, as requested by Parent.

(b) Procedures for Surrender.

(i) As promptly as reasonably practicable after the Effective Time (and in any event within five (5) Business Days thereafter), the Surviving Corporation (with the assistance of Parent if necessary) shall cause the Exchange Agent to provide or make available to each holder of record of Eligible Shares (each a “Holder”) notice advising such holders of the effectiveness of the Merger, which notice shall include (I) appropriate transmittal materials (including a customary letter of transmittal) specifying that delivery shall be effected, and risk of loss and title to the Certificates representing the Eligible Shares shall pass, only upon delivery of the Certificates to the Exchange Agent (or affidavits of loss in lieu of the Certificates, as provided in Section 4.2(e)), such materials to be in such form and have such other provisions as Parent desires and reasonably acceptable to the Company (such acceptance not to be unreasonably conditioned, withheld or delayed) and (II) instructions for effecting the surrender of the Certificates (or affidavits of loss in lieu of the Certificates, as provided in Section 4.2(e)) to the Exchange Agent in exchange for the Merger Consideration including the Fractional Share Consideration, if any, and dividends or distributions payable pursuant to Section 4.2(i), if any, that such holder is entitled to receive as a result of the Merger pursuant to Section 4.1. In furtherance of the foregoing, at or prior to the Effective Time, the Company shall deliver to Parent a complete and accurate listing of all Holders as of immediately prior to the Effective Time, including the name and address of each such Holder and the number of Company Shares held by such Holder.

(ii) Upon physical surrender to the Exchange Agent of Certificates representing Eligible Shares (or affidavits of loss in lieu of the Certificates, as provided in Section 4.2(e)) together with the letter of transmittal, duly completed and validly executed, and such other documents as may be reasonably required by the Exchange Agent in accordance with the terms of the materials and instructions provided by the Exchange Agent, the holder of such Certificate shall be entitled to receive in exchange therefor, and Parent shall cause the Exchange Agent to issue or pay, as applicable, and deliver as promptly as reasonably practicable to such holders, (1) the number of Parent Shares (whether represented in certificated or non-certificated direct registration form) issued pursuant to Section 4.1 and (2) an amount in cash in immediately available funds (after giving effect to any required Tax withholdings as provided in Section 4.2(g)) sufficient to make payments of Fractional Share Consideration, if any, and any dividends or distributions payable pursuant to Section 4.2(i), if any, in each case, in respect of the Eligible Shares represented by such Certificate (or an affidavit of loss in lieu of the Certificate, as provided in Section 4.2(e)).

(iii) For the avoidance of doubt, no interest will be paid or accrued for the benefit of any holder of Eligible Shares on any amount payable upon the surrender of any Eligible Shares as contemplated by the foregoing provisions of this Section 4.2(b), and any Certificates so surrendered shall be cancelled by the Exchange Agent. Any Merger Consideration (including any Fractional Share Consideration), together with any dividends or distributions payable pursuant to Section 4.2(i), issued or paid upon surrender of a Certificate will be deemed to have been paid in full satisfaction of all rights pertaining to such Certificate.

-7-

(iv) In the event of a transfer of ownership of any Eligible Shares that are not registered in the stock transfer books of the Company or if the applicable Merger Consideration is to be issued or paid in a name other than that in which the Certificate or Certificates surrendered are registered in the stock transfer books or ledger of the Company, it shall be a condition of the issuance or payment of the applicable Merger Consideration that the Certificate formerly representing such Eligible Shares is properly endorsed and otherwise in proper form for surrender and presented to the Exchange Agent, accompanied by all documents required to evidence and effect such transfer and to evidence that any applicable transfer, documentary, sales, use, stamp or registration Taxes or other similar Taxes have been paid or are not applicable, in each case, in form and substance, reasonably satisfactory to Parent and the Exchange Agent.

(v) Subject to the terms of the Exchange Agent Agreement, Parent, in the exercise of its reasonable discretion, shall have the right to make all determinations, consistent with the terms of this Agreement, governing the validity of any such transmittal materials described herein and compliance by any holder of Company Shares with the procedures contemplated by this Agreement.

(c) Transfers. From and after the Effective Time, the stock transfer books of the Company shall be closed with respect to the Company Shares outstanding immediately prior to the Effective Time and there shall be no transfers on the stock transfer books of the Company of any Company Shares outstanding immediately prior to the Effective Time. If, after the Effective Time, any Certificate formerly representing any Company Shares is presented to the Surviving Corporation, Parent or the Exchange Agent for transfer, it shall be cancelled or, in the case such shares are Eligible Shares, cancelled and exchanged for the applicable Merger Consideration including the Fractional Share Consideration, if any, and dividends or distributions payable pursuant to Section 4.2(i), if any, to which the holder thereof is entitled in accordance with this Article IV.

(d) Termination of Exchange Fund. Any portion of the Exchange Fund (including the proceeds of any investments thereof (if any)) that remains unclaimed by the holders of Company Shares for one (1) year from and after the Closing Date shall be delivered to the Surviving Corporation. Any holder of Eligible Shares who has not theretofore complied with the procedures, materials and instructions contemplated by this Article IV shall thereafter look only to the Surviving Corporation for issuance or payment of the Merger Consideration (after giving effect to any required Tax withholdings as provided in Section 4.2(g)) payable pursuant to Section 4.1. Notwithstanding anything to the contrary in the foregoing, none of the Surviving Corporation, Parent, the Exchange Agent or any other Person shall be liable to any former holder of Company Shares for any portion of the Exchange Fund properly delivered to a public official pursuant to applicable abandoned property, escheat or similar Laws. Any Merger Consideration remaining unclaimed by the holders of Certificates immediately prior to such time as such amounts would otherwise escheat to, or become property of, any Governmental Entity will, to the extent permitted by applicable Law, become the property of the Surviving Corporation or a Subsidiary thereof designated by the Surviving Corporation, free and clear of any claim or interest of any Person previously entitled thereto.

(e) Lost, Stolen or Destroyed Certificates. In the event any Certificate representing Eligible Shares shall have been lost, stolen or destroyed, upon the making of an

-8-

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 customary amount and upon such terms as may be reasonably required by Parent as indemnity against any claim that may be made against it or the Surviving Corporation with respect to such Certificate, the Exchange Agent will issue or pay the applicable Merger Consideration issuable or payable pursuant to Section 4.1, including the Fractional Share Consideration, if any, and dividends or distributions payable pursuant to Section 4.2(i), if any, deliverable in respect of such lost, stolen or destroyed Certificate.

(f) Dissenting Shares.

(i) Notwithstanding anything to the contrary contained in this Agreement, to the extent that the provisions of Section 262 of the DGCL are or prior to the Effective Time may become applicable to the Merger, then any Company Share, as of the Effective Time, held by a holder who has properly exercised (and has not effectively withdrawn or lost) his, her or its appraisal rights under Section 262 of the DGCL (a “Dissenting Share”) shall not be converted into or represent the right to receive the consideration set forth in Section 4.1 and the holder of such Dissenting Share shall be entitled only to such rights as may be granted to such holder in Section 262 of the DGCL; provided, that if the status of any such Dissenting Share as a share carrying appraisal or dissenters’ rights shall be withdrawn in accordance with Section 262 of the DGCL, or if any such Dissenting Share shall otherwise lose its status as a share carrying appraisal or dissenters’ rights in accordance with Section 262 of the DGCL, then, as of the later of the Effective Time or the loss of such status, such Dissenting Share shall automatically be converted into and shall represent only the right to receive (upon the surrender of the Certificate representing such share in accordance with Section 4.2(b)) the consideration set forth in Section 4.1, without any interest thereon.

(ii) The Company shall give Parent prompt notice and a copy of any written demand received by the Company prior to the Effective Time to require payment for Company Shares pursuant to Section 262 of the DGCL and of any other demand, withdrawal, notice or instrument delivered to the Company prior to the Effective Time pursuant to the DGCL. The Company shall not make, propose, enter into or approve any payment or settlement offer prior to the Effective Time with respect to any such demand without the prior written consent of Parent.

(g) Withholding Rights. Notwithstanding anything in this Agreement to the contrary, each of Parent, the Exchange Agent and the Surviving Corporation (and any of their respective Subsidiaries) shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any Person such amounts as it is required to deduct and withhold with respect to the making of such payment under the Code, or any other applicable state, local or non-U.S. Tax Law. To the extent that amounts are so withheld, such withheld amounts (i) shall be remitted to the applicable Governmental Entity and (ii) shall be treated for all purposes of this Agreement as having been paid to the Person in respect of which such deduction and withholding was made.

(ii) Parent shall pay to the Exchange Agent an amount in cash to be deposited following the Effective Time, sufficient for the Exchange Agent to pay each holder of Certificates an amount in cash (rounded to the nearest cent) equal to the product of (1) the fraction of a Parent Share (rounded to the nearest thousandth when expressed in decimal form) to which such holder (taking into account all fractional Parent Shares to be received by such holder) would otherwise have been entitled to receive pursuant to Section 4.1, multiplied by (2) the Reference Price.

(i) Dividends or Distributions with Respect to Parent Shares. No dividends or other distributions with respect to Parent Shares with a record date after the Effective Time will be paid to the holder of any unsurrendered Certificate with respect to the right to receive the Parent Shares represented thereby, and all such dividends and other distributions will be paid by Parent to the Exchange Agent and will be included in the Exchange Fund, in each case, until the surrender of such Certificate (or an affidavit of loss in lieu of the Certificate, as provided in Section 4.2(e)) in accordance with this Agreement. Subject to applicable Laws, following surrender of any such Certificate (or an affidavit of loss in lieu of the Certificate, as provided in Section 4.2(e)) there will be paid to the holder thereof, without interest, (i) promptly, the amount of dividends or other distributions with a record date after the Effective Time theretofore paid with respect to such Parent Shares to which such holder is entitled pursuant to Section 4.1, and (ii) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time but prior to such surrender and with a payment date subsequent to such surrender payable with respect to such Parent Shares.

4.3 Treatment of Equity Awards and Company Warrant.

(a) Treatment of Company Options. Immediately prior to the Effective Time, each unexpired, unexercised and outstanding stock option to purchase Company Shares granted under the Company Stock Plan or otherwise (a “Company Option”) shall, automatically and without any action on the part of the holder thereof, cease to represent a right to purchase Company Shares and be converted immediately prior to the Effective Time into an option, on the same terms and conditions applicable to such Company Option immediately prior to the Effective Time (including any terms and conditions that provide for accelerated vesting in connection with the Merger or the other transactions contemplated by this Agreement), to purchase the number of Parent Shares that is equal to the product of, rounded down to the nearest whole share, (i) the number of Company Shares subject to such Company Option immediately prior to the Effective Time, multiplied by (ii) the Exchange Ratio, at an exercise price per Parent Share (rounded up to the nearest whole cent) equal to (A) the per-Company Share exercise price of such Company Option immediately prior to the Effective Time divided by (B) the Exchange Ratio; provided that the adjustments provided in this Section 4.3(a) with respect to any Company Options are intended to be effected in a manner that is consistent with Section 424(a) of the Code and Section 409A of the Code.

-10-

(c) Treatment of Company Warrant. Immediately prior to the Effective Time, the outstanding warrant to purchase 2,000,000 Company Shares subject to the Common Stock Purchase Warrant, dated June 30, 2016, issued to NantWorks, LLC (the “Company Warrant”) shall, automatically and without any action on the part of the holder thereof, cease to represent a right to purchase Company Shares and be converted immediately prior to the Effective Time into a warrant, on the same terms and conditions applicable to the Company Warrant immediately prior to the Effective Time, to purchase the number of Parent Shares that is equal to the product of, rounded to the nearest whole share, (i) the number of Company Shares subject to the Company Warrant immediately prior to the Effective Time, multiplied by (ii) the Exchange Ratio, at an exercise price per Parent Share (rounded to the nearest whole cent) equal to (A) the per-Company Share exercise price of the Company Warrant immediately prior to the Effective Time divided by (B) the Exchange Ratio.

(d) Corporate Actions. At or prior to the Effective Time, the Company, the Company Board and any duly authorized committee of the Company Board, as applicable, shall adopt any resolutions and take any actions which are necessary to effectuate the provisions of Section 4.3(a), Section 4.3(b) and Section 4.3(c). At the Effective Time, Parent shall assume all of the obligations of the Company relating to Company Equity Awards outstanding immediately prior to the Effective Time, including under the Company Stock Plan and the agreements evidencing the grants thereof. At the Effective Time, Parent shall assume all of the obligations of the Company relating to the Company Warrant, and if requested by the holder of the Company Warrant, Parent shall issue to such holder a replacement warrant in form reasonably satisfactory to such holder reflecting the assumption by the Parent of the obligations of the Company relating to the Company Warrant and the adjustments thereto reflected in Section 4.3(c). Promptly following the Effective Time, Parent shall file a registration statement on Form S-8 (or other applicable form) with respect to the Parent Shares subject to such Company Equity Awards converted pursuant to this Section 4.3 and shall maintain the effectiveness of such registration statement or registration statements (and maintain the current status of the prospectus or prospectuses contained therein) for so long as such converted Company Equity Awards remain outstanding. As soon as practicable after the Effective Time, Parent shall deliver to the holders of Company Equity Awards appropriate notices (if applicable) setting forth such holders’ rights pursuant to the Company Stock Plan, and the agreements evidencing the grants of such Company Equity Awards shall continue in effect on the same terms and conditions, subject to the adjustments required by this Section 4.3 after giving effect to the transactions contemplated by this Agreement.

Parent’s internal control over financial reporting (as defined in Rule 13a-15 or 15d-15, as applicable, under the Exchange Act) is effective in providing reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with GAAP and includes policies and procedures that (i) pertain to the maintenance of records that are in reasonable detail and accurately and fairly reflect the transactions and dispositions of the assets of Parent, (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with GAAP, and that receipts and expenditures of Parent are being made only in accordance with authorizations of management and directors of Parent and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of Parent’s assets that could have a material effect on its financial statements. Since January 1, 2020, neither Parent nor its auditors have identified (A) any significant deficiency or material weakness in the design or operation of the system of internal accounting controls used by Parent, (B) any fraud that involves Parent, its Subsidiaries, Parent’s management or other employees who have a role in the preparation of the financial statements or the internal accounting controls utilized by Parent, or (C) any claim or allegation regarding any of the foregoing.

(d) Each of the consolidated balance sheets included in or incorporated by reference into the Parent Reports (including the related notes and schedules) presents fairly, in all material respects, the consolidated financial position of Parent and its Subsidiaries as of its date and each of the related consolidated statements of operations and comprehensive loss, stockholders’ equity and of cash flows included in, or incorporated by reference into, the Parent Reports (including any related notes and schedules) presents fairly, in all material respects, the consolidated results of operations and cash flows of Parent and its Subsidiaries for the periods set forth therein (subject, in the case of unaudited statements, to notes and normal year-end audit

-30-

adjustments). Each such consolidated balance sheet or related consolidated statements of operations and comprehensive loss, of stockholders’ equity and of cash flows included in or incorporated by reference into the Parent Reports (including the related notes and schedules) complied as to form at the time it was filed (or, if amended prior to the date hereof, as of the date of such amendment) in all material respects with applicable accounting requirements and the published rules and regulations of the SEC with respect thereto and was prepared in conformity with GAAP (except, in the case of unaudited interim financial statements, as permitted by Form 10-Q of the SEC) applied on a consistent basis during the periods involved (except as may be indicated in the notes thereto).

(iii) resolve or agree to do any of the foregoing.

Notwithstanding anything to the contrary in the foregoing provisions of this Section 7.2(a), prior to the time, but not after, the Company Stockholder Approval is obtained, the Company and its Representatives may (A) provide information in response to a request therefor by a Person who has made an unsolicited bona fide written Company Acquisition Proposal after the date of this Agreement that did not result from a breach in any material respect of this Section 7.2 if the Company receives from the Person so requesting such information an executed confidentiality agreement on terms not less restrictive in the aggregate to such Person than those contained in the Confidentiality Agreement; provided, however, that such information has previously been made available to Parent and the Special Committee or is made available to Parent and the Special Committee prior to or promptly after the time such information is made available to such Person; and (B) engage or otherwise participate in any discussions or negotiations with any Person who has made such an unsolicited bona fide written Company Acquisition Proposal, if (I) the Company shall have provided the Special Committee with a copy of the written Company Acquisition Proposal, (II) prior to taking any action described in clause (A) or (B) directly above, the Company Board (acting with the approval of the Independent Director) determines in good faith after consultation with its outside legal counsel that failure to take such action would be inconsistent with the directors’ fiduciary duties under applicable Law and (III) in each such case referred to in clause (A) or (B) directly above, the Company Board (acting with the approval of the Independent Director) has determined in good faith based on the information then available and after consultation with its outside legal counsel and financial advisor that such Company Acquisition Proposal either constitutes a Company Superior Proposal or could reasonably be expected to result in a Company Superior Proposal.

(b) No Change in Company Recommendation or Alternative Acquisition Agreement. The Company Board and each committee of the Company Board shall not:

-43-

(i) (A) withhold, withdraw, qualify or modify (or publicly propose or resolve to withhold, withdraw, qualify or modify), in a manner adverse to Parent, the Company Recommendation, (B) authorize, approve, recommend or otherwise declare advisable, or publicly propose to authorize, approve, recommend or otherwise declare advisable, any Company Acquisition Proposal or proposal that would reasonably be expected to lead to a Company Acquisition Proposal, (C) fail to include the Company Recommendation in the Joint Disclosure Statement or (D) if any Company Acquisition Proposal structured as a tender offer or exchange offer is commenced, fail to recommend against acceptance of such tender offer or exchange offer by the Company’s stockholders within ten (10) Business Days of the commencement thereof (any of the foregoing actions or inactions in this Section 7.2(b)(i) by the Company Board or any committee of the Company Board, a “Change of Company Recommendation”) or otherwise resolve or agree to take any of the foregoing actions in this Section 7.2(b)(i); or

(ii) cause or permit the Company to enter into any letter of intent, memorandum of understanding, agreement in principle, acquisition agreement, merger agreement or other similar agreement (other than a confidentiality agreement referred to in Section 7.2(a) entered into in compliance with Section 7.2(a)) relating to any Company Acquisition Proposal (an “Alternative Company Acquisition Agreement”) or otherwise resolve or agree to do so.

Notwithstanding anything to the contrary set forth in this Section 7.2(b), the Company Board (acting with the approval of the Independent Director) may, prior to but not after the time the Company Stockholder Approval is obtained, (A) make a Change of Company Recommendation if an Intervening Event has occurred and the Company Board (acting with the approval of the Independent Director) has determined in good faith, after consulting with its financial advisor and outside legal counsel, that failure to take such action would be inconsistent with such directors’ fiduciary duties under applicable Law, or (B) make a Change of Company Recommendation and/or terminate this Agreement pursuant to Section 9.3(c), if the Company receives a Company Acquisition Proposal and the Company Board (acting with the approval of the Independent Director) has determined in good faith, after consulting with its financial advisor and outside legal counsel, that such Company Acquisition Proposal constitutes a Company Superior Proposal and that failure to take such action would be inconsistent with such directors’ fiduciary duties under applicable Law; provided that the Company Board may not take any such action unless (I) prior to making such Change of Company Recommendation and/or terminating this Agreement pursuant to Section 9.3(c), as applicable, the Company provides prior written notice to the Special Committee at least four (4) Business Days in advance (the “Notice Period”) of its intention to take such action and the basis thereof, which notice shall include, in the case of a Company Superior Proposal, a written copy of the Company Superior Proposal (and copies of the then latest draft agreements reflecting the terms of the Company Superior Proposal) and, in the case of an Intervening Event, a reasonably detailed description of such Intervening Event, (II) during the Notice Period, the Company shall, and shall cause its employees, financial advisor and outside legal counsel to, be reasonably available to negotiate with Parent in good faith should Parent propose to make amendments or other revisions to the terms and conditions of this Agreement such that, in the case of a Company Superior Proposal, such Company Acquisition Proposal no longer constitutes a Company Superior Proposal or, in the case of an Intervening Event, the failure to take such action would no longer be inconsistent with the directors’ fiduciary duties under applicable Law as determined in the good faith judgment of the Company Board (acting with the approval of the Independent Director), after consulting with its financial advisor and outside legal

-44-

counsel, and (III) the Company Board (acting with the approval of the Independent Director), has taken into account any amendments or other revisions to the terms and conditions of this Agreement agreed to by Parent in writing prior to the end of the Notice Period and has determined in good faith, after consulting with its financial advisor and outside legal counsel, that a failure to make such Change of Company Recommendation and/or terminate this Agreement pursuant to Section 9.3(c), as applicable, would still be inconsistent with the directors’ fiduciary duties under applicable Law; it being understood that any amendments or other revisions to any Company Acquisition Proposal will be deemed to be a new Company Acquisition Proposal, including for purposes of the Notice Period; provided, however, subsequent to the initial Notice Period, the Notice Period shall be reduced to two (2) Business Days.

(c) Certain Permitted Disclosure. Nothing contained in this Section 7.2 shall prohibit the Company Board from (i) taking and disclosing a position contemplated by Rule 14e-2(a)(2) or (3) promulgated under the Exchange Act, or (ii) making any disclosure to the stockholders of the Company that is required by applicable Law, which actions shall not constitute or be deemed to constitute a Change of Company Recommendation; provided, however, that (A) any such disclosure permitted under clause (i) above that relates to a Company Acquisition Proposal shall be deemed a Change of Company Recommendation unless the Company Board expressly publicly reaffirms the Company Recommendation in connection with such disclosure and (B) any Change of Company Recommendation may only be made in accordance with Section 7.2(b).

(d) Notice. The Company agrees that it will promptly (and, in any event, within forty-eight (48) hours) notify the Special Committee if any inquiries, proposals or offers with respect to any Company Acquisition Proposal or that could reasonably be expected to lead to any Company Acquisition Proposal are received by, any information in connection therewith is requested from, or any such discussions or negotiations related thereto are sought to be initiated or continued with, it or any of its Representatives indicating, in connection with such notice, the name of such Person making the Company Acquisition Proposal and providing copies of any written requests, proposals or offers, including proposed agreements and the material terms and conditions of any oral proposals or offers, and thereafter shall keep the Special Committee reasonably informed, on a reasonably current basis, of the status and terms of any such inquiries, proposals or offers (including any amendments thereto) and the status of any such discussions or negotiations.

7.3 Parent Acquisition Proposals.

(a) No Solicitation or Negotiation.

(ii) cause or permit Parent to enter into any letter of intent, memorandum of understanding, agreement in principle, acquisition agreement, merger agreement or other similar agreement (other than a confidentiality agreement referred to in Section 7.3(a) entered into in compliance with Section 7.3(a)) relating to any Parent Acquisition Proposal (an “Alternative Parent Acquisition Agreement”) or otherwise resolve or agree to do so.

Notwithstanding anything to the contrary set forth in this Section 7.3(b), the Parent Board (acting upon the recommendation of the Special Committee) or the Special Committee may, prior to but not after the time the Parent Stockholder Approval and the Parent Majority of the Minority Stockholder Approval is obtained, (A) make a Change of Parent Recommendation if a Parent Intervening Event has occurred and the Parent Board (acting upon the recommendation of the Special Committee) or the Special Committee has determined in good faith, after consulting with its financial advisor and outside legal counsel, that failure to take such action would be inconsistent with such directors’ fiduciary duties under applicable Law, or (B) make a Change of Parent Recommendation and/or terminate this Agreement pursuant to Section 9.4(c), if Parent receives a Parent Acquisition Proposal and the Parent Board (acting upon the recommendation of the Special Committee) or the Special Committee has determined in good faith, after consulting with its financial advisor and outside legal counsel, that such Parent Acquisition Proposal constitutes a Parent Superior Proposal and that failure to take such action would be inconsistent with such directors’ fiduciary duties under applicable Law; provided that neither the Parent Board nor the Special Committee may take any such action (and the Special Committee may not recommend to the Parent Board to take such action) unless (I) prior to making such Change of Parent Recommendation and/or terminating this Agreement pursuant to Section 9.4(c), as applicable, Parent provides prior written notice to the Company at least four (4) Business Days in advance (the “Parent Notice Period”) of its intention to take such action and the basis thereof, which notice shall include, in the case of a Parent Superior Proposal, a written copy of the Parent Superior Proposal (and copies of the then latest draft agreements reflecting the terms of the Parent Superior Proposal) and, in the case of a Parent Intervening Event, a reasonably detailed description of such Parent Intervening Event, (II) during the Parent Notice Period, Parent shall, and shall cause its employees, financial advisor and outside legal counsel to, be reasonably available to negotiate with the Company in good faith should the Company propose to make amendments or other revisions to the terms and conditions of this Agreement such that, in the case of a Parent Superior Proposal, such Parent Acquisition Proposal no longer constitutes a Parent Superior Proposal or, in the case

-47-

of a Parent Intervening Event, the failure to take such action would no longer be inconsistent with the directors’ fiduciary duties under applicable Law as determined in the good faith judgment of the Parent Board (acting upon the recommendation of the Special Committee) or the Special Committee, after consulting with its financial advisor and outside legal counsel, and (III) the Parent Board (acting upon the recommendation of the Special Committee) or the Special Committee, as the case may be, has taken into account any amendments or other revisions to the terms and conditions of this Agreement agreed to by the Company in writing prior to the end of the Parent Notice Period and has determined in good faith, after consulting with its financial advisor and outside legal counsel, that a failure to make such Change of Parent Recommendation and/or terminate this Agreement pursuant to Section 9.4(c), as applicable, would still be inconsistent with the directors’ fiduciary duties under applicable Law; it being understood that any amendments or other revisions to any Parent Acquisition Proposal will be deemed to be a new Parent Acquisition Proposal, including for purposes of the Parent Notice Period; provided, however, subsequent to the initial Parent Notice Period, the Parent Notice Period shall be reduced to two (2) Business Days.

7.4 Preparation of Form S-4 and Joint Disclosure Statement.

(a) As promptly as practicable after the execution of this Agreement, (i) the Company and Parent shall jointly prepare and cause to be filed with the SEC a joint proxy and consent solicitation statement (as amended or supplemented from time to time, the “Joint

-48-

Disclosure Statement”) to be (x) sent to the stockholders of Parent relating to the Parent Stockholders Meeting and (y) sent to the stockholders of the Company for purposes of soliciting written consents to obtain the Company Stockholder Approval and (ii) Parent and the Company shall jointly prepare and Parent shall cause to be filed with the SEC a registration statement on Form S-4 (as amended or supplemented from time to time, the “Form S-4”) pursuant to which the Parent Shares to be issued in the Merger will be registered with the SEC, in which the Joint Disclosure Statement will be included as a prospectus, in connection with the registration under the Securities Act of the Parent Shares to be issued pursuant to the Merger. Each of Parent and the Company shall use its reasonable best efforts to have the Form S-4 declared effective under the Securities Act as promptly as practicable after such filing, and, prior to the effective date of the Form S-4, Parent shall take all action reasonably required (other than qualifying to do business in any jurisdiction in which it is not now so qualified or filing a general consent to service of process) to be taken under any applicable state securities Laws in connection with the issuance of Parent Shares pursuant to the Merger. Each of Parent and the Company shall furnish all information as may be reasonably requested by the other in connection with any such action and the preparation, filing and distribution of the Form S-4 and the Joint Disclosure Statement. Without limiting the foregoing, the Company shall furnish to Parent, as soon as reasonably practicable, the consolidated financial statements of the Company and its Subsidiaries required for inclusion in the Form S-4 and the Joint Disclosure Statement, which financial statements shall comply with all applicable SEC regulations and be suitable for inclusion in the Form S-4 and the Joint Disclosure Statement and shall be prepared in accordance with GAAP as applied on a consistent basis during the periods involved (except in each case as described in the notes thereto).

(b) As promptly as practicable after the Form S-4 shall have become effective (but in no event later than five (5) Business Days after the date that the Form S-4 is declared effective), each of Parent and the Company shall use its reasonable best efforts to cause the Joint Disclosure Statement to be mailed to the holders of the Parent Shares and the holders of the Company Shares, respectively. No filing of, or amendment or supplement to, the Form S-4 will be made by Parent, and no filing of, or amendment or supplement to, the Joint Disclosure Statement will made by the Company or Parent, in each case, without providing the other party a reasonable opportunity to review and comment thereon. If at any time prior to the Effective Time any information relating to the Company or Parent, or any of their respective Affiliates, directors or officers, should be discovered by the Company or Parent which should be set forth in an amendment or supplement to either the Form S-4 or the Joint Disclosure Statement, so that either such document would not include any misstatement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they are made, not misleading, the party that discovers such information shall promptly notify the other party and an appropriate amendment or supplement describing such information shall be promptly filed with the SEC and, to the extent required by Law, disseminated to the stockholders of the Company and Parent. Parent and the Company shall notify each other promptly of the time when the Form S-4 has become effective, of the issuance of any stop order or suspension of the qualification of the Parent Shares issuable in connection with the Merger for offering or sale in any jurisdiction, or of the receipt of any comments from the

-49-

SEC or the staff of the SEC and of any request by the SEC or the staff of the SEC for amendments or supplements to the Joint Disclosure Statement or the Form S-4 or for additional information. Unless a Change of Company Recommendation or a Change of Parent Recommendation shall have occurred in accordance with Section 7.2 or Section 7.3, as applicable, the Company Recommendation and the Parent Recommendation, respectively, shall be included in the Joint Disclosure Statement.

7.5 Company Stockholder Approval; Parent Stockholders Meetings.

(a) Company Stockholder Approval. As promptly as practicable after the effectiveness of the Form S-4, the Company shall solicit approval by written consent from a sufficient number of holders of Company Shares for purposes of obtaining the Company Stockholder Approval. The Company shall use its reasonable best efforts to take, or cause to be taken, all actions, and do or cause to be done all things necessary, proper or advisable on its part to cause the Company Stockholder Approval to be obtained. Notwithstanding anything to the contrary contained in this Agreement, if subsequent to the date of this Agreement a Change of Company Recommendation shall have occurred, the Company shall nevertheless submit the Agreement to the holders of Company Shares for adoption by written consent unless and until this Agreement is terminated in accordance with its terms.

(b) Parent Stockholders Meeting. Promptly after the date hereof and in consultation with the Company, Parent will set preliminary record dates for the Parent Stockholders Meeting and commence broker searches pursuant to Section 14a-13 of the Exchange Act in connection therewith.

Parent, acting through the Parent Board or the Special Committee, shall, unless the Parent Board has made a Change of Parent Recommendation in accordance with Section 7.3, (1)

-50-

(iii) (A) this Agreement is terminated by either the Company or Parent pursuant to Section 9.2(b) under circumstances in which the Parent Majority of the Minority Stockholder Approval is not obtained; and (B) (I) a bona fide Parent Acquisition Proposal shall have been (1) made known to the Special Committee or publicly made or disclosed and (2) not withdrawn (which withdrawal shall be public if such Parent Acquisition Proposal has been publicly made or disclosed) prior to the date of the Parent Stockholders Meeting and (II) concurrently with or within twelve (12) months of such termination, Parent shall have consummated a Parent Acquisition Proposal or entered into a definitive Alternative Parent Acquisition Agreement relating to a Parent Acquisition Proposal that is subsequently consummated (whether or not, in each case, such Parent Acquisition Proposal is the same one as the Parent Acquisition Proposal referred to in clause (B)(I)); provided that, for purposes of clause (B) of this Section 9.5(c)(iii), references

-62-

to “twenty percent (20%)” in the definition of “Parent Acquisition Proposal” shall be deemed to be references to “fifty percent (50%)”;

then Parent shall pay to the Company (or its designee(s)), by wire transfer of same-day funds, a termination fee of $34,070,000 (the “Parent Termination Fee”) (x) in the case of Section 9.5(c)(i), substantially concurrently with the termination of this Agreement pursuant to Section 9.4(c); (y) in the case of Section 9.5(c)(ii), no later than two (2) Business Days after the date of termination of this Agreement pursuant to Section 9.3(a); and (z) in the case of Section 9.5(c)(iii), immediately prior to or substantially concurrent with the last to occur of the events set forth in Section 9.5(c)(iii). It is understood and agreed that in no event shall Parent be required to pay the Parent Termination Fee on more than one occasion.

(d) Each of the Company and Parent acknowledges that the agreements contained in Section 9.5(b) and Section 9.5(c) are an integral part of the transactions contemplated by this Agreement, and that, without these agreements, the Parties would not enter into this Agreement and the damages resulting from termination of this Agreement under circumstances where a Termination Fee or a Parent Termination Fee is payable are uncertain and incapable of accurate calculation and, therefore, each of the Termination Fee payable pursuant to Section 9.5(b) and the Parent Termination Fee payable pursuant to Section 9.5(c) is not a penalty but rather constitutes an amount akin to liquidated damages in a reasonable amount that will compensate Parent or the Company, as applicable, for the efforts and resources expended and opportunities forgone while negotiating this Agreement and in reliance on this Agreement and on the expectation of the consummation of the Merger and the other transactions contemplated by this Agreement. Accordingly, if (i) the Company fails to promptly pay the Termination Fee due by it pursuant to Section 9.5(b) or (ii) Parent fails to promptly pay the Parent Termination Fee due by it pursuant to Section 9.5(c) and, in order to obtain such payment Parent or the Company, as applicable, commences a Proceeding that results in a judgment against the Company or Parent, as applicable, for the Termination Fee set forth in Section 9.5(b) or the Parent Termination Fee set forth in Section 9.5(c), the Company or Parent, as applicable, shall pay to Parent or the Company, as applicable, their costs and expenses (including attorneys’ fees) in connection with such Proceeding, together with interest on the amount of the fee at the prime rate set forth in The Wall Street Journal, Eastern Edition, in effect on the date such payment was required to be made from the date such payment was required to be made through the date of payment.

(e) In the event that the Termination Fee is paid to Parent in circumstances in which such fee is payable pursuant to Section 9.5(b), payment of the Termination Fee, together with any costs and expenses and interest payable pursuant to Section 9.5(d), shall be the sole and exclusive remedy of Parent and its Related Persons in such capacity against the Company and its Related Persons in such capacity (the “Company Related Persons”) for any cost, expense, loss, damage, liability or obligation suffered as a result of the failure of the Merger or the other transactions contemplated by this Agreement to be consummated or for a breach or failure to perform hereunder or otherwise, and upon payment of such amount none of the Company or any Company Related Persons shall have any further liability or obligation relating to or arising out of this Agreement or the transactions contemplated by this Agreement; provided that nothing in this Section 9.5(e) shall relieve any Party of any liability or damages resulting from fraud or any Willful and Material Breach of this Agreement. The provisions of this Section 9.5(e) are intended to be for the benefit of, and shall be enforceable by, each of the Company Related Persons.

-63-

(f) In the event that the Parent Termination Fee is paid to the Company in circumstances in which such fee is payable pursuant to Section 9.5(c), payment of the Parent Termination Fee, together with any costs and expenses and interest payable pursuant to Section 9.5(d), shall be the sole and exclusive remedy of the Company and its Related Persons in such capacity against Parent and its Related Persons in such capacity (the “Parent Related Persons”) for any cost, expense, loss, damage, liability or obligation suffered as a result of the failure of the Merger or the other transactions contemplated by this Agreement to be consummated or for a breach or failure to perform hereunder or otherwise, and upon payment of such amount none of Parent or any Parent Related Persons shall have any further liability or obligation relating to or arising out of this Agreement or the transactions contemplated by this Agreement; provided that nothing in this Section 9.5(f) shall relieve any Party of any liability or damages resulting from fraud or any Willful and Material Breach of this Agreement. The provisions of this Section 9.5(f) are intended to be for the benefit of, and shall be enforceable by, each of the Parent Related Persons.
