ARTICLE II

CONVERSION OF SHARES; EXCHANGE OF CERTIFICATES

Section 2.1 Effect on Capital Stock.

(a) At the Effective Time, by virtue of the Merger and without any action on the part of Parent, the Company, Merger Sub or the holder of any shares of Company Common Stock or common stock of Merger Sub:

(i) Common Stock of Merger Sub. Each share of Merger Sub Common Stock issued and outstanding immediately prior to the Effective Time shall be converted into and become one validly issued, fully paid and nonassessable share of common stock, par value $0.01 per share, of the Surviving Corporation. From and after the Effective Time, all certificates representing the common stock of Merger Sub shall be deemed for all purposes to represent the number of shares of common stock of the Surviving Corporation into which they were converted in accordance with the immediately preceding sentence.

(ii) Cancellation of Certain Stock. Each share of Company Common Stock issued and outstanding immediately prior to the Effective Time that is owned or held in treasury by

the Company or owned by any Subsidiary of the Company and each share of Company Common Stock issued and outstanding immediately prior to the Effective Time that is owned by Parent, Merger Sub or any other direct or indirect Subsidiary of Parent shall no longer be outstanding and shall automatically be cancelled and shall cease to exist (the "Cancelled Shares"), and no consideration shall be delivered in exchange therefor.

(iii) Conversion of Company Common Stock. Each share of Company Common Stock issued and outstanding immediately prior to the Effective Time (other than Dissenting Shares or Cancelled Shares) shall be automatically converted into the right to receive from Merger Sub a portion of a validly issued, fully paid and non-assessable Parent Common Share (the "Exchange Ratio") equal to 0.078; provided, however, if the Average Parent Share Price is less than $3.22, the Exchange Ratio shall be equal to a decimal (rounded to the nearest one-one thousandth place) determined by dividing $0.25 by the Average Parent Share Price; provided, further, however, if the Average Parent Share Price is greater than $3.86, the Exchange Ratio shall be equal to a decimal (rounded to the nearest one-one thousandth place) determined by dividing $0.30 by the Average Parent Share Price. Notwithstanding the preceding sentence, if the aggregate number of Parent Common Shares to be issued pursuant to this Section 2.1(a) plus the number of Parent Common Shares underlying each Company Warrant assumed by Parent pursuant to Section 2.3(c) would exceed 19.9% of the Parent Common Shares outstanding immediately prior to the Effective Time (the "Maximum Share Amount"), then appropriate adjustments shall be made to the Merger Consideration (as defined below) to be issued pursuant thereto such that (1) the aggregate number of Parent Common Shares to be included in the Merger Consideration is reduced to the extent required such that the aggregate number of Parent Common Shares to be so issued does not exceed the Maximum Share Amount and (2) an aggregate amount of cash consideration will be included in the Merger Consideration, such aggregate amount equal to the Average Parent Share Price multiplied by the number of Parent Common Shares so reduced (the "Cash Consideration"). Any reduction to the number of Parent Common Shares to be issued in the Merger, and any Cash Consideration to be included in the Merger Consideration, in each case in accordance with this Article II, shall be applied pro rata to the shares of Company Common Stock (including shares of Company Common Stock issuable in respect of Company Warrants) outstanding as of immediately prior to the Effective Time. As of the Effective Time, each share of Company Common Stock converted into the right to receive from Merger Sub the Parent Common Shares to be issued pursuant to this Article II plus, if applicable, the Cash Consideration (the "Merger Consideration") shall no longer be outstanding, shall automatically be cancelled and shall cease to exist, and uncertificated shares of Company Common Stock represented by book-entry form ("Book-Entry Shares") and each certificate that, immediately prior to the Effective Time, represented any such shares of Company Common Stock (each, a "Certificate") shall thereafter represent only the right to receive, pursuant to the terms of this Agreement, the Merger Consideration into which the shares of Company Common Stock represented by such Book-Entry Share or Certificate have been converted pursuant to this Section 2.1, as well as any cash in lieu of fractional Parent Common Shares to be issued or paid in consideration therefor and any dividends or other distributions to which holders of Company Common Stock become entitled in accordance with Section 2.2(e).

(b) Certain Adjustments. If, between the date of this Agreement and the Effective Time, the outstanding shares of Company Common Stock shall have been changed into a different number of shares or a different class of shares by reason of any stock dividend, subdivision, reorganization, reclassification, recapitalization, stock split, reverse stock split, combination or exchange of shares, or any similar event shall have occurred, then the Exchange Ratio shall be equitably adjusted, without duplication, to proportionally reflect such change. If, between the date of this

Agreement and the Effective Time, the outstanding Parent Common Shares shall have been changed into a different number of shares or a different class of shares by reason of any stock dividend, subdivision, reorganization, reclassification, recapitalization, stock split, reverse stock split, combination or exchange of shares, or any similar event shall have occurred, then the Exchange Ratio shall be equitably adjusted, without duplication, to proportionally reflect such change. Nothing in this Section 2.1(b) shall be construed to permit the Company or Parent to take any action with respect to its securities that is prohibited by the terms of this Agreement.

(c) No Fractional Shares. Notwithstanding any other provision of this Agreement, no fractional Parent Common Shares shall be issued in connection with the Merger and no certificates or scrip representing fractional Parent Common Shares shall be delivered upon the conversion of Company Common Stock pursuant to Section 2.1(a)(iii). In lieu thereof, each holder of shares of Company Common Stock converted pursuant to the Merger who would otherwise have been entitled to receive a fraction of a Parent Common Share but for this Section 2.1(c) (after aggregating all shares represented by the Certificates (or affidavits of loss in lieu thereof) and Book-Entry Shares delivered by such holder) shall be entitled to receive a cash payment (without interest) rounded to the nearest whole cent in an amount determined by the Exchange Agent (as defined below) after selling the aggregate of such Parent Common Shares in the public market (the "Fractional Share Cash Amount"). The Exchange Agent will make available the net proceeds from such sale, after deducting any required withholding Taxes and brokerage charges, commissions and transfer Taxes, on a pro rata basis, without interest, as soon as practicable to the holders of Company Common Stock entitled to receive such Fractional Share Cash Amount. No such holder shall be entitled to dividends, voting rights or any other rights in respect of any fractional Parent Common Share.

Section 2.2 Exchange of Certificates.

(a) Appointment of Exchange Agent. Prior to the Effective Time, Parent shall appoint a bank or trust company reasonably acceptable to the Company to act as exchange agent (the "Exchange Agent") for the payment of the Merger Consideration and shall enter into an agreement reasonably acceptable to the Company (the "Exchange Agent Agreement") relating to the Exchange Agent's responsibilities under this Agreement.

(b) Deposit of Merger Consideration. At the Effective Time, Parent shall cause Merger Sub to deposit with the Exchange Agent, evidence of Parent Common Shares in book-entry form representing the number of Parent Common Shares held by Merger Sub and sufficient to deliver the stock portion of aggregate Merger Consideration payable pursuant to Section 2.1(a)(iii) as well as, if applicable, the Cash Consideration (such Parent Common Shares, Cash Consideration, if applicable, together with any cash in lieu of fractional Parent Common Shares to be paid pursuant to Section 2.1(c) and any dividends or distributions which a holder of shares of Company Common Stock has the right to receive pursuant to Section 2.2(e), the "Exchange Fund"). Parent agrees to promptly deliver to the Exchange Agent from time to time as needed, until the termination of the Exchange Fund pursuant to Section 2.2(h), any dividends or other distributions which a former holder of Company Common Stock has the right to receive pursuant to Section 2.2(e) in respect of the Parent Common Shares to which they are entitled that are held in the Exchange Fund. The Exchange Fund will not be used for any purpose other than the payment of the Merger Consideration and dividends and other distributions in accordance with this Article II.

(c) Exchange Procedures. As soon as reasonably practicable after the Effective Time, Parent shall cause the Exchange Agent to mail to each holder of record of shares of Company Common Stock immediately prior to the Effective Time (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon proper delivery of the Certificates to the Exchange Agent and shall, subject to the Company's reasonable approval, be in such form and have such other provisions (including customary provisions with respect to delivery of an "agent's message" with respect to Book-Entry Shares) as Parent shall reasonably

designate) (the "Letter of Transmittal") and (ii) instructions for use in effecting the surrender of Certificates or Book-Entry Shares in exchange for the Merger Consideration, Fractional Share Cash Amount and any dividends or other distributions to which such Certificates or Book-Entry Shares become entitled in accordance with Section 2.2(e).

(d) Surrender of Certificates or Book-Entry Shares. Upon surrender of Certificates or Book-Entry Shares to the Exchange Agent (in the case of Book-Entry Shares, by receipt of the Exchange Agent of an "agent's message") together with the Letter of Transmittal, duly completed and validly executed in accordance with the instructions thereto, and such other documents as may customarily be required by the Exchange Agent, the holder of such Certificates or Book-Entry Shares shall be entitled to receive in exchange therefor the Merger Consideration into which the shares represented by such Certificates or Book-Entry Shares have been converted pursuant to this Agreement, together with any Fractional Share Cash Amount and any dividends or other distributions to which such Certificates or Book-Entry Shares become entitled in accordance with Section 2.2(e). In the event of a transfer of ownership of shares of Company Common Stock that is not registered in the transfer or stock records of the Company, any Cash Consideration to be paid upon, and the Parent Common Shares to be issued upon, due surrender of the Certificate or Book-Entry Share formerly representing such shares of Company Common Stock may be paid or issued, as the case may be, to such a transferee if such Certificate or Book-Entry Share is presented to the Exchange Agent, accompanied by all documents required to evidence and effect such transfer and to evidence that any applicable stock transfer or other similar Taxes have been paid or are not applicable. Until surrendered as contemplated by this Section 2.2, each Certificate and Book-Entry Share (other than Dissenting Shares, Cancelled Shares or shares of Company Common Stock owned or held by any direct or indirect Subsidiary of the Company immediately prior to the Effective Time) shall be deemed at any time after the Effective Time to represent only the right to receive, upon such surrender pursuant to the terms of this Agreement, the Merger Consideration into which the shares represented by such Certificates or Book-Entry Shares have been converted pursuant to this Agreement, together with Fractional Share Cash Amount and any dividends or other distributions to which such Certificates or Book-Entry Shares become entitled in accordance with Section 2.2(e).

(e) Treatment of Unexchanged Shares. No dividends or other distributions, if any, with a record date at or after the Effective Time with respect to Parent Common Shares, shall be paid to the holder of any unsurrendered share of Company Common Stock to be converted into Parent Common Shares and Cash Consideration, if applicable, pursuant to Section 2.1(a)(iii) until such holder shall surrender such share in accordance with this Section 2.2. After the surrender in accordance with this Section 2.2 of shares of Company Common Stock to be converted into Parent Common Shares and Cash Consideration, if applicable, pursuant to Section 2.1(a)(iii), the holder thereof shall be entitled to receive (in addition to the applicable portion of the Merger Consideration and any Fractional Share Cash Amount payable to such holder pursuant to this Article II) (i) at the time of any such surrender, any such dividends or other distributions with a record date at or after the Effective Time, without any interest thereon, which theretofore had become payable with respect to the Parent Common Share represented by such shares of Company Common Stock and (ii) at the appropriate payment date, the amount of dividends or other distribution with a record date at or after the Effective Time and a payment date subsequent to such surrender payable with respect to the number of whole Parent Common Shares into which such shares of Company Common Stock are converted pursuant to Section 2.1(a)(iii).

(f) No Further Ownership Rights in Company Common Stock. The Parent Common Shares delivered and the Cash Consideration paid in accordance with the terms of this Article II upon conversion of any shares of Company Common Stock shall be deemed to have been delivered and paid in full satisfaction of all rights pertaining to such shares of Company Common Stock. From and after the Effective Time, subject to applicable Law, in the case of the cancellation of the Cancelled Shares, (i) all holders of Certificates and Book-Entry Shares shall cease to have any rights as stockholders of

the Company other than the right to receive the applicable portion of the Merger Consideration into which the shares represented by such Certificates or Book-Entry Shares have been converted pursuant to this Agreement upon the surrender of such Certificate or Book-Entry Share in accordance with Section 2.2(d) (together with any Fractional Share Cash Amount and any dividends or other distributions to which such Certificates or Book-Entry Shares become entitled in accordance with Section 2.2(e)), without interest, and (ii) the stock transfer books of the Company shall be closed with respect to all shares of Company Common Stock outstanding immediately prior to the Effective Time and there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of shares of Company Common Stock that were outstanding immediately prior to the Effective Time. If, after the Effective Time, any Certificates or Book-Entry Shares formerly representing shares of Company Common Stock are presented to the Surviving Corporation, Parent or the Exchange Agent for any reason, such Certificates or Book-Entry Shares shall be cancelled and exchanged as provided in this Article II.

(g) Investment of Exchange Fund. The Exchange Agent shall invest any cash included in the Exchange Fund if and as directed by Parent; provided that no gain or loss thereon shall affect the amounts payable to the holders of shares of Company Common Stock following consummation of the Merger pursuant to this Article II and Parent shall take all actions necessary to ensure that the Exchange Fund includes at all times cash sufficient to satisfy Parent's obligations under this Article II. Subject to Parent's obligations pursuant to this Article II, any interest or other income resulting from such investments shall be paid to Parent, upon demand.

(h) Termination of Exchange Fund. At any time following the 12-month anniversary of the Closing Date, Parent shall be entitled to require the Exchange Agent to deliver to it any portion of the Exchange Fund (including any interest or other amounts received with respect thereto) that remains unclaimed by, or otherwise undistributed to, the holders of Certificates and Book-Entry Shares, and any holder of Certificates or Book-Entry Shares who has not theretofore complied with this Article II shall thereafter look only to Parent (subject to abandoned property, escheat or other similar Laws), as general creditors thereof, for satisfaction of its claim for Merger Consideration and any dividends and distributions which such holder has the right to receive pursuant to this Article II without any interest thereon.

(i) No Liability. None of Parent, the Company, Merger Sub or the Exchange Agent shall be liable to any person in respect of any portion of the Exchange Fund or the Merger Consideration delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law. Notwithstanding any other provision of this Agreement, any portion of the Merger Consideration or the cash to be paid in accordance with this Article II that remains unclaimed by the holders of Certificates and Book-Entry Shares, as of immediately prior to the date on which such portion of the Merger Consideration or such cash would otherwise escheat to or become the property of any Governmental Authority, shall, to the extent permitted by applicable Law, become the property of the Surviving Corporation, free and clear of all claims or interest of any person previously entitled thereto.

(j) Withholding Rights. Each of the Surviving Corporation, Parent, Merger Sub and the Exchange Agent (without duplication) shall be entitled to deduct and withhold from amounts otherwise payable pursuant to this Agreement, such amounts as is required to be deducted or withheld with respect to the making of such payment under applicable Tax Law. Any amounts so deducted and withheld shall be paid over to the appropriate Taxing Authority and shall be treated for all purposes of this Agreement as having been paid to the person in respect of which such deduction or withholding was made. No later than three Business days prior to any payment required to be made hereunder to any Company Stockholder or holder of Company Warrants, Parent shall notify the Company in writing of an intent to so deduct or withhold from such payment and shall (and shall cause its Affiliates to) give the Company reasonable opportunity to provide any information or other documentation, and otherwise reasonably cooperate with the Company, so as to minimize or eliminate any such otherwise

required deduction or withholding, provided, however, that Parent shall determine if any amounts are required to be deducted or withheld.

(k) Lost Certificates. If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen or destroyed and, if required by Parent or the Exchange Agent, the posting by such person of a bond in such amount as Parent or the Exchange Agent may determine is reasonably necessary as indemnity against any claim that may be made against it or the Surviving Corporation with respect to such Certificate, the Exchange Agent (or, if subsequent to the termination of the Exchange Fund and subject to Section 2.2(h), Parent) shall deliver, in exchange for such lost, stolen or destroyed Certificate, the Merger Consideration and any dividends and distributions deliverable in respect thereof pursuant to this Agreement.

Section 2.3 Company Options and Company Warrants.

(a) Each option to purchase shares of Company Common Stock granted pursuant to the Company Stock Plans that will be outstanding and unexercised as of immediately prior to the Effective Time (each, a "Company Option"), shall, at the Effective Time, (i) to the extent not then vested or exercisable, become fully vested and exercisable and (ii) be cancelled in exchange for a cash payment in an amount equal to the excess, if any, of the Merger Consideration over the exercise price of such Company Option. All such payments shall be made within five Business Days following the Effective Time and shall be subject to all applicable federal, state and local Tax withholding requirements. In the event that the exercise price of a Company Option equals or exceeds the Merger Consideration, such Company Option shall be cancelled for no consideration. In calculating the value of the Merger Consideration for purposes this Section 2.3(a), the value of Parent Common Shares shall be determined by using the Average Parent Share Price.

(b) Promptly following the execution and delivery of this Agreement, the Company shall take all actions reasonably necessary to ensure compliance with the obligations of the Company under the warrants to purchase Company Common Stock (collectively, the "Company Warrants") in accordance with the terms thereof, including the giving of any notice (in form and substance reasonably acceptable to Parent) required thereunder. To the extent any holder of a Company Warrant exercises its rights pursuant to section 9(c) of the Company Warrant, Parent shall ensure that the Company will have the requisite funds necessary to satisfy the Company's obligation in respect thereof.

(c) With respect to any Company Warrants that have not been cancelled in exchange for a cash payment from the Company in accordance with section 9(c) of such Company Warrant, at the Effective Time, each Company Warrant that is outstanding and unexercised immediately prior to the Effective Time, shall become converted into and become a warrant exercisable to receive the Merger Consideration and Parent shall assume each such Company Warrant in accordance with its terms. All rights with respect to Company Common Stock under Company Warrants assumed by Parent shall thereupon be converted into rights with respect to Parent Common Shares. Accordingly, from and after the Effective Time: (i) each Company Warrant assumed by Parent may be exercised solely for the Merger Consideration; (ii) the number of Parent Common Shares subject to, and the portion of the Cash Consideration, if any, payable in respect of, each Company Warrant assumed by Parent shall be determined by (A) multiplying (1) the number of shares of Company Common Stock issuable upon exercise of the Company Warrant that were subject to such Company Warrant immediately prior to the Effective Time by (2) the Exchange Ratio (after giving effect to the second sentence of Section 2.1(a)(iii) if applicable) and rounding the resulting number down to the nearest whole number of Parent Common Shares, and adding to such amount the portion of the Cash Consideration, if any, payable in respect of the number of shares of Company Common Stock issuable upon exercise of the Company Warrant that were subject to such Company Warrant immediately prior to the Effective Time; (iii) the per share exercise price for the Parent Common Shares issuable upon exercise of each Company Warrant assumed by Parent shall be determined by dividing the per share exercise price for

the Company Common Stock issuable upon exercise of such Company Warrant, as in effect immediately prior to the Effective Time, by the Exchange Ratio (without giving effect to the second sentence of Section 2.1(a)(iii) if applicable) and rounding the resulting exercise price up to the nearest whole cent; and (iv) any restriction on any Company Warrant assumed by Parent shall continue in full force and effect and the term and other provisions of such Company Warrant shall otherwise remain unchanged.

(d) Prior to the Effective Time, the Company shall take all actions that may be reasonably necessary (under the Company Stock Plans, the Company Warrants and otherwise) to effectuate the provisions of this Section 2.3 and to ensure that, from and after the Effective Time, holders of Company Options have no rights with respect thereto and holders of Company Warrants have no rights with respect thereto other than those specifically provided in this Section 2.3 and in the Company Warrants.

Section 2.4 Further Assurances. If at any time after the Effective Time, Parent or the Surviving Corporation reasonably believes or is advised that any further instruments, deeds, assignments, actions or assurances are reasonably necessary or desirable to consummate the Merger or to carry out the purposes and intent of this Agreement, then Parent and the Surviving Corporation and their respective officers and directors shall be authorized to execute and deliver all such proper instruments, deeds, assignments or assurances and do all other things reasonably necessary or desirable to consummate the Merger and to carry out the purposes and intent of this Agreement.

Section 2.5 Dissenting Shares. Notwithstanding anything in this Agreement to the contrary, shares of Company Common Stock that are outstanding immediately prior to the Effective Time and that are held by any Company Stockholder who shall have neither voted in favor of the Merger nor consented thereto in writing and who have properly demanded appraisal for such shares of Company Common Stock in accordance with Section 262 of the DGCL (collectively, the "Dissenting Shares") shall not be converted into the right to receive the Merger Consideration as provided in this Agreement, but rather, the holders of Dissenting Shares shall be entitled only to payment of the appraised value of such Dissenting Shares in accordance with the provisions of Section 262 of the DGCL (and, at the Effective Time, such Dissenting Shares shall no longer be outstanding and shall automatically be cancelled and shall cease to exist, and such holders shall cease to have any right with respect thereto, except the right to receive the appraised value of such Dissenting Shares in accordance with the provisions of Section 262 of the DGCL); provided, however, that if any such holder fails to perfect or otherwise shall waive, withdraw or lose the right to appraisal under the provisions of Section 262 of the DGCL, then the right of such holder to be paid the appraised value of such holder's Dissenting Shares will cease and such Dissenting Shares will be deemed to have been converted as of the Effective Time into, and to have become exchangeable solely for, the right to receive the Merger Consideration, without interest, as provided in this Agreement. The Company will notify Parent as promptly as reasonably practicable of any demands received by the Company for appraisal of any shares of Company Common Stock, withdrawals thereof and any other instruments delivered to the Company pursuant to Section 262 of the DGCL, and Parent will have the right to participate in all negotiations and proceedings with respect to such demands. The Company shall not, except with the prior written consent of Parent, voluntarily make any payment with respect to, or settle, or offer or agree to settle, any such demand for payment. Any portion of the Merger Consideration made available to the Exchange Agent pursuant to Section 2.2(b) to pay for shares of Company Common Stock for which appraisal rights have been perfected shall be returned to Parent upon demand.

The Company is not currently in material default of the performance, observance or fulfillment of any provision of its certificate of incorporation, as amended and restated, and bylaws, in each case as in effect on the date of this Agreement (the "Company Organizational Documents").

Each of the Patents included in the Registered IP that are owned solely by the Company or any of its Subsidiaries (and, to the Knowledge of the Company, with respect to any co-owned Patents) properly identifies by name each and every inventor of the claims thereof as determined in accordance with the Laws of the jurisdiction in which such Patent is issued or pending. All Registered IP included in the Company Intellectual Property is valid, subsisting and enforceable.

Section 3.11(a)(ii) of the Company Disclosure Schedule describes each filing, payment, and action that must be made or taken on or before the date that is one hundred and eighty (180) days after the date of this Agreement in order to maintain each such item of Registered IP that is listed on Section 3.11(a)(i) of the Company Disclosure Schedule.

(b) The Company or its Subsidiaries have good, valid, unexpired and enforceable title (free and clear of all Liens other than Permitted Liens) or otherwise have the valid and enforceable right to use all of the Intellectual Property used in the conduct of their business as currently conducted. There is no Intellectual Property owned by any person that (i) the Company or any of its Subsidiaries in good faith believes is valid and enforceable, (ii) is required by the Company or any of its Subsidiaries to conduct their business as currently conducted, and (iii) to the extent authorization is required, the Company is not currently authorized to use. Nothwithstanding the foregoing, nothing in this Section 3.11(b) shall be deemed to be a representation regarding infringement, misappropriation or other violation of Intellectual Property rights of others.

Section 5.3 Access.

(a) For purposes of furthering the Transactions, during the period from the date of this Agreement until the Effective Time or, if earlier, the termination of this Agreement in accordance with its terms, the Company shall (i) afford Parent and its Representatives reasonable access during normal business hours upon reasonable advance notice to the Company, to its and its Subsidiaries' officers, employees, properties, contracts, commitments, books and records and any report, schedule or other document filed or received by it pursuant to the requirements of applicable Laws (other than information concerning the value of the Company or relating to the process leading to the negotiation and execution of this Agreement and any communications relating to any Company Acquisition Proposal or Company Competing Transaction) and (ii) use its reasonable best efforts to make available to Parent, during normal business hours and at the Company's principal place of business or via telephone, the Company's accountants, consultants, legal counsel, financial advisors and representatives, in each case to the extent reasonably requested by Parent in order to discuss the affairs of the Company and its Subsidiaries. During such period, the Company shall, and shall cause its Subsidiaries to, without limitation to the preceding obligations, make available to Parent a copy of any written communication (and a summary of any material oral communication) received from the FDA or similar Governmental Authority promptly after receipt of such communication. All access pursuant to this Section 5.3(a) shall be (i) conducted in such a manner as not to interfere unreasonably with the normal operations of the Company or any of its Subsidiaries and (ii) coordinated through the Chief Executive Officer of the Company or a designee thereof.

(b) Notwithstanding anything to the contrary contained in this Section 5.3, neither the Company nor its Subsidiaries nor their respective Representatives shall be required to provide any access, or make available any document, correspondence or information, if doing so would, in the reasonable judgment of the Company's outside legal counsel, (i) jeopardize the attorney-client privilege of the Company or any of its Subsidiaries or (ii) conflict with any (A) Law applicable to the Company or any of its Subsidiaries or the assets, or operation of the business, of the Company or any of its Subsidiaries or (B) Material Company Contract to which the Company or any of its Subsidiaries is party or by which any of their assets or properties are bound; provided, however, that in such instances the Company shall inform Parent of the general nature of the information being withheld and the basis for withholding and, upon Parent's request, reasonably cooperate with Parent to provide such information, in whole or in part, in a manner that would not result in any of the outcomes described in the foregoing clauses (i) and (ii), including using commercially reasonable efforts to seek consent from the applicable third party to any such Material Company Contract under which disclosure is prohibited.

(c) No investigation by Parent or its Representatives shall affect or be deemed to modify or waive the representations and warranties of the Company set forth in this Agreement.

(d) The Parties hereby agree that all information provided to them or their respective Representatives in connection with this Agreement and the consummation of the Transactions shall be governed in accordance with the Confidentiality Agreement, dated as of May 8, 2014, between the Company and Parent (the "Confidentiality Agreement"), which shall continue in full force and effect in accordance with its terms.

Section 5.4 No Solicitation.

(a) During the period from the date of this Agreement until the Effective Time or, if earlier, the termination of this Agreement in accordance with its terms, the Company will not, and will cause its Subsidiaries not to, and will use commercially reasonable efforts to cause each controlled Affiliate and any Representative of the Company, any of its Subsidiaries or any such controlled Affiliate not to, and on becoming aware of it will use commercially reasonable efforts to stop any such person from continuing to, directly or indirectly, (i) solicit, initiate or knowingly encourage, knowingly cooperate with any person regarding, or knowingly facilitate (including by way of furnishing material, non-public information) any inquiries or proposals regarding, or that would reasonably be expected to lead to, any Company Competing Transaction (any of the foregoing inquiries or proposals being referred to herein as a "Company Acquisition Proposal"), (ii) participate in any discussions or negotiations regarding any Company Acquisition Proposal (but the foregoing will not prohibit the Company or any of its Representative from making a person aware or otherwise informing such person of the provisions of this Section 5.4), or (iii) enter into any letter of intent, memorandum of understanding, agreement in principle, acquisition agreement, merger agreement, option agreement, joint venture agreement, partnership agreement or other agreement, other than any Acceptable Confidentiality Agreement, regarding, or that is intended to result in, or would reasonably be expected to lead to, any Company Acquisition Proposal (a "Company Acquisition Agreement").

(b) As used in this Agreement, "Company Competing Transaction" means any of (i) a transaction, including any tender offer, exchange offer or share exchange, pursuant to which any third person or group (other than Parent or any of its Affiliates or any group of which Parent or its Affiliates is a member), or the stockholders of such third person, directly or indirectly, acquires or would acquire beneficial ownership (as defined in Rule 13d-3 under the Exchange Act) of 15% or more of the outstanding shares of common stock of the Company or of the outstanding voting power of the Company (or options, rights or warrants to purchase, or securities convertible into or exchangeable for, such common stock or other securities representing such voting power), whether from the Company or pursuant to a tender offer or exchange offer or otherwise, (ii) a merger, share exchange, consolidation or business combination pursuant to which any third person or group of persons (other than Parent or any of its Affiliates or any group of which Parent or its Affiliates is a member), or the stockholders of such third person or persons, beneficially owns or would beneficially own 15% or more of the outstanding shares of common stock or the outstanding voting power of the Company, or, if applicable, any surviving entity or the parent entity resulting from any such transaction, immediately upon consummation thereof, (iii) a recapitalization of the Company or any of its Subsidiaries or any transaction similar to a transaction referred to in clause (ii) above involving the Company or any of its Subsidiaries pursuant to which any third person or group of persons (other than Parent or any of its Affiliates or any group of which Parent or its Affiliates is a member), or its stockholders, beneficially owns or would beneficially own 15% or more of the outstanding shares of common stock or the outstanding voting power of the Company or such Subsidiary or, if applicable, the parent entity resulting from any such transaction immediately upon consummation thereof or (iv) any transaction pursuant to which any third person or group of persons (other than Parent or any of its Affiliates) directly or indirectly (including by way of merger, consolidation, share exchange, other business combination, partnership, joint venture or otherwise) acquires or would acquire control of assets (including for this purpose the equity securities of, or other ownership interest in, Subsidiaries of the Company and securities of the entity surviving any merger or business combination involving any of the Subsidiaries of the Company) of the Company or any of its Subsidiaries representing 15% or more of the fair market value of all the assets of the Company and its Subsidiaries, taken as a whole, immediately prior to such transaction. Wherever the term "group" is used in this Agreement, it is used as defined in Rule 13d-3 under the Exchange Act.

(c) The Company will notify Parent promptly (but in no event later than one Business Day) after the Company has Knowledge of its receipt of any Company Acquisition Proposal, or any material modification of or material amendment to any Company Acquisition Proposal, or any inquiry or request for non-public information relating to the Company or any of its Subsidiaries or for access to the properties, books or records of the Company or any of its Subsidiaries by any person that is reasonably likely to lead to a Company Acquisition Proposal. Such notice to Parent will be made orally and confirmed in writing and will include the identity of the person or persons making the Company Acquisition Proposal or inquiry or requesting non-public information or access to the properties, books or records of the Company or any of its Subsidiaries, and a copy of the Company Acquisition Proposal or, if not in writing, a written summary in reasonable detail of the material terms of any such Company Acquisition Proposal, inquiry or request or modification or amendment to a Company Acquisition Proposal. The Company will (i) keep Parent reasonably informed, on a current basis, of any material changes in the status of, and any material changes or modifications in the terms of, any such Company Acquisition Proposal, inquiry or request, and (ii) provide to Parent as soon as practicable after receipt or delivery thereof with copies of all material documents (including electronic material) or other substantive materials that contain financial terms, material conditions or other material terms of such Company Competing Transaction that are sent or provided to the Company from any third party in connection with any Company Acquisition Proposal or sent or provided by the Company to any third party in connection with any Company Acquisition Proposal; provided, however, that any material written material or material correspondence will be sent or provided pursuant to clause (ii) within one Business Day after receipt or delivery thereof. The Company will not enter into any agreement on or after the date of this Agreement that would prevent the Company from providing any information required by this Section 5.4 to Parent.

(d) Notwithstanding anything to the contrary in this Agreement, at any time prior to obtaining the Company Stockholder Approval, the Company or its Representatives may (i) to the extent necessary, contact any person or group of persons (and their Representatives) that makes a Company Acquisition Proposal solely to clarify the terms of such Company Acquisition Proposal that are unclear to the Company and that the Company reasonably determines are material to its analysis of such Company Acquisition Proposal, and (ii) furnish or cause to be furnished information to, and enter or cause to be entered into discussions with, and only with, the person or group (and its Representatives) who has made a Company Acquisition Proposal that was not solicited on or after the date of this Agreement in violation of Section 5.4(a) if the Company Board (A) determines in good faith (after consultation with its outside legal counsel and financial advisor or advisors) that such Company Acquisition Proposal constitutes or is reasonably likely to lead to a Company Superior Proposal, (B) provides notice to Parent of its intent to furnish information to or enter into discussions with such person in accordance with this Section 5.4(d), and (C) enters into a confidentiality agreement with such person containing terms that are determined in good faith by the Company to be no less favorable to the Company in the aggregate than those contained in the Confidentiality Agreement (it being understood that such confidentiality agreement and any related agreements will not include any provision calling for any exclusive right to negotiate with such person or having the effect of prohibiting the Company from satisfying its obligations under this Agreement) provided that in no event will any such confidentiality agreement be required to contain any provision that would prevent the person making a Company Acquisition Proposal from making Company Acquisition Proposals to the Company Board (any such agreement, an "Acceptable Confidentiality Agreement"). Unless such information has been previously provided to Parent, all information provided by the Company to the person making such Company Acquisition Proposal will be promptly provided to Parent.

(e) As used in this Agreement, "Company Superior Proposal" means a bona fide written Company Acquisition Proposal made by a third person (or group of persons) to consummate a merger, consolidation, business combination or other similar transaction involving the Company pursuant to which the stockholders of the Company immediately preceding such transaction would hold less than

50% of the outstanding shares of common stock of, or less than 50% of the outstanding voting power of, the Company, any surviving entity or the parent entity resulting from any such transaction immediately upon consummation thereof that the Company Board (after consultation with its outside legal counsel and its financial advisor or advisors) determines in good faith (i) to be more favorable from a financial point of view to the Company's stockholders than the Merger and (ii) is reasonably capable of being completed in accordance with its terms.

(f) Except as permitted by Sections 5.4(g) or 5.4(h), the Company Board will not (i) withhold, withdraw or modify in a manner adverse to Parent the Company Board Recommendation or the approval or declaration of advisability by the Company Board of this Agreement and the Transactions (including the Merger) or (ii) resolve, agree or propose publicly to take any such actions (each such action set forth in this sentence of this Section 5.4(f) being referred to herein as an "Adverse Recommendation Change") or approve, adopt or recommend, or cause or permit the entry into or propose publicly to do so with respect to, any Company Acquisition Agreement (other than an Acceptable Confidentiality Agreement).

(g) Notwithstanding anything to the contrary in this Agreement, if, at any time prior to obtaining the Company Stockholder Approval (i) the Company receives a Company Acquisition Proposal, (ii) such Company Acquisition Proposal did not result from a breach of Section 5.4(a) and (iii) the Company Board determines in good faith after consultation with its outside legal counsel and with its financial advisor that (A) such Company Acquisition Proposal constitutes a Company Superior Proposal, and (B) in light of such Company Acquisition Proposal, failure to make an Adverse Recommendation Change would be inconsistent with the directors' fiduciary obligations under applicable Law, the Company Board may, subject to the provisions of Section 5.4(i) and Section 7.2, make an Adverse Recommendation Change or terminate this Agreement to enter into a definitive Company Acquisition Agreement with respect to such Company Superior Proposal; provided, however, that the Company shall not terminate this Agreement pursuant to the foregoing, and any purported termination pursuant to the foregoing shall be void and of no force or effect, unless in advance of or concurrently with such termination the Company pays, or causes to be paid, the Termination Fee to Parent in immediately available funds in accordance with Section 7.2(c).

(h) Notwithstanding anything in this Agreement to the contrary, if (i) an Intervening Event occurs or arises after the date of this Agreement and prior to obtaining the Company Stockholder Approval and (ii) the Company Board determines in good faith after consultation with its outside legal counsel and with its financial advisor that in light of the existence of such Intervening Event, failure to make an Adverse Recommendation Change would constitute a breach of the directors' fiduciary obligations under applicable Law, then prior to obtaining the Company Stockholder Approval, the Company Board may, subject to the provisions of Section 5.4(i) and Section 7.2, make an Adverse Recommendation Change.

(i) Prior to making any Adverse Recommendation Change as a result of a Company Superior Proposal or an Intervening Event or terminating this Agreement pursuant to Section 5.4(g), the Company shall deliver to Parent a written notice (a "Change in Recommendation Notice") stating that the Company Board intends to take such action pursuant to Section 5.4(g) or 5.4(h), as the case may be, and, together with such notice, provide a copy of the proposed form of the Company Acquisition Agreement or a description of the Intervening Event, as applicable. During the four Business Day period commencing, if Parent's receipt of the Change in Recommendation Notice is prior to 5:00 p.m. Pacific Coast time, on the date of Parent's receipt of such Change in Recommendation Notice, or, if such receipt is after 5:00 p.m. Pacific Coast time, on the Business Day first following the date of Parent's receipt of such Change in Recommendation Notice (the "Negotiation Period"), the Company shall make its directors, officers and outside advisors reasonably available for the purpose of engaging in negotiations with Parent and its Representatives (to the extent Parent desires to negotiate) regarding a possible amendment to this Agreement so that the Company Acquisition Proposal that is

the subject of the Change in Recommendation Notice ceases to be a Company Superior Proposal, in the case of an Adverse Recommendation Change or termination of this Agreement pursuant to Section 5.4(g), or so as to obviate the need for an Adverse Recommendation Change as a result of the Intervening Event, in the case of an Adverse Recommendation Change pursuant to Section 5.4(h). Any written proposal made by Parent to amend this Agreement during the Negotiation Period shall be considered by the Company Board in good faith. With respect to a Change in Recommendation Notice issued in connection with a Company Acquisition Proposal, each time the financial or other material terms of such Company Acquisition Proposal are amended, the Company will deliver to Parent a new Change in Recommendation Notice (including as attachments thereto a copy of the new Company Acquisition Agreement related to such amended proposal and copies of any material documents related thereto), and the Negotiation Period shall be extended by an additional two Business Days from the date of Parent's receipt of such new Change in Recommendation Notice. For the avoidance of doubt, a new Negotiation Period shall be commenced in respect of a new Change in Recommendation Notice received after the Execution Date.

(j) (i) Nothing contained in this Section 5.4 will prohibit the Company from taking or disclosing to its stockholders a position required by Rule 14e-2(a) or Rule 14d-9 promulgated under the Exchange Act and (ii) no disclosure that the Company Board may determine (after consultation with legal counsel) that it or the Company is required to make under applicable Law will constitute a violation of this Agreement; provided, however, that in any event the Company Board shall not make an Adverse Recommendation Change except in accordance with Section 5.4(g) and Section 5.4(h). Any disclosure by the Company relating to a Company Acquisition Proposal shall be deemed to be an Adverse Recommendation Change by the Company unless the Company Board reaffirms its recommendation and declaration of advisability with respect to this Agreement in such disclosure.

(k) The Company and its Subsidiaries will immediately cease and cause to be terminated any existing discussions or negotiations with any persons (other than Parent to this Agreement) conducted heretofore with respect to any Company Acquisition Proposal, and will request that all persons, other than Parent, who have been furnished confidential information regarding the Company or its Subsidiaries in connection with the solicitation of or discussions regarding a Company Acquisition Proposal within the 12 months prior to the date of this Agreement promptly to return or destroy such information.

(l) It is understood that any violation of the restrictions set forth in this Section 5.4 by any Representative of the Company or any of its Subsidiaries or controlled Affiliates will be deemed to be a breach of this Section 5.4 by the Company.

Section 5.5 Preparation of the Parent Registration Statement and the Company Proxy Statement; Company Stockholders Meeting.

(a) As promptly as practicable following the date of this Agreement, the Company shall prepare and cause to be filed with the SEC the Company Proxy Statement, and Parent shall prepare and cause to be filed with the SEC the Parent Registration Statement, in which the Company Proxy Statement will be included as a prospectus, and Parent shall use commercially reasonable efforts to have the Parent Registration Statement declared effective under the Securities Act as promptly as practicable after such filing. Each of Parent and the Company shall furnish all information concerning such Party and its Affiliates to the other, and provide such other assistance, as may be reasonably requested in connection with the preparation, filing and distribution of the Parent Registration Statement and the Company Proxy Statement. Each of Parent and the Company shall promptly notify the other upon the receipt of any comments from the SEC or any request from the SEC for amendments or supplements to the Parent Registration Statement or the Company Proxy Statement, as applicable, and shall provide the other with copies of all correspondence between it and its Representatives, on one hand, and the SEC, on the other hand. Each of Parent and the Company shall

use commercially reasonable efforts to respond as promptly as practicable to any comments from the SEC with respect to the Parent Registration Statement or the Company Proxy Statement, respectively. Notwithstanding the foregoing, prior to filing the Parent Registration Statement (or any amendment or supplement thereto) or mailing the Company Proxy Statement (or any amendment or supplement thereto) or responding to any comments of the SEC with respect thereto, each of Parent and the Company shall, other than with respect to filings relating to Company Acquisition Proposals, (i) provide the other a reasonable opportunity to review and comment on such document or response (including the proposed final version of such document or response) and (ii) give reasonable consideration in such document or response to all comments reasonably proposed by the other. Parent shall advise the Company, promptly after receipt of notice thereof, of the time of effectiveness of the Parent Registration Statement, the issuance of any stop order relating thereto or the suspension of the qualification of Parent Common Shares constituting Merger Consideration for offering or sale in any jurisdiction, and Parent shall use commercially reasonable efforts to have any such stop order or suspension lifted, reversed or otherwise terminated. Parent shall also take any other action (other than qualifying to do business in any jurisdiction in which it is not now so qualified) required to be taken under the Securities Act, the Exchange Act, any applicable foreign or state securities or "blue sky" Laws in connection with the Merger, the Share Issuance, the Subscription and the issuance of Parent Common Shares under the Company Stock Plans. The Company shall furnish all available information concerning the Company and the holders of Company Common Stock and as may be reasonably requested in connection with any such action.

(b) If, prior to the Effective Time, any event occurs with respect to the Company or any of its Subsidiaries, or any change occurs with respect to other information supplied by the Company for inclusion in the Company Proxy Statement or the Parent Registration Statement, which is required to be described in an amendment of, or a supplement to, the Company Proxy Statement or the Parent Registration Statement, the Company shall promptly notify Parent of such event, and the Company and Parent shall cooperate in the prompt filing with the SEC of any necessary amendment or supplement to the Company Proxy Statement and the Parent Registration Statement and, as required by Law, in disseminating the information contained in such amendment or supplement to the Company's stockholders. Nothing in this Section 5.5(b) shall limit the obligations of any Party under Section 5.5(a).

(c) If prior to the Effective Time, any event occurs with respect to Parent or any of its Subsidiaries, or any change occurs with respect to other information supplied by Parent for inclusion in the Company Proxy Statement or the Parent Registration Statement, which is required to be described in an amendment of, or a supplement to, the Company Proxy Statement or the Parent Registration Statement, Parent shall promptly notify the Company of such event, and Parent and the Company shall cooperate in the prompt filing with the SEC of any necessary amendment or supplement to the Company Proxy Statement and the Parent Registration Statement and, as required by Law, in disseminating the information contained in such amendment or supplement to the Company's stockholders. Nothing in this Section 5.5(c) shall limit the obligations of any Party under Section 5.5(a).

(d) The Company, in consultation with Parent, shall, as soon as practicable following the effectiveness of the Parent Registration Statement, duly call, give notice of, convene and hold a meeting of Company Stockholders for the purpose of seeking the Company Stockholders Approval (the "Company Stockholders Meeting"). The Company, in consultation with Parent, shall use commercially reasonable efforts to: (i) cause the Parent Registration Statement to be declared effective by the SEC as promptly as practicable (and in any event on or prior to the seventh Business Day following the Execution Date); (ii) cause the mailing of the Company Proxy Statement to the Company's stockholders to commence no later than the first Business Day following the date that the Parent Registration Statement is declared effective by the SEC; (iii) initially establish the date of the Company Stockholders Meeting on a date that is no later than the 21st Business Day after the date of mailing of the Company Proxy Statement; and (iv) unless the Company Board shall have made an

Adverse Recommendation Change in accordance with Section 5.4, (A) solicit proxies in favor of the Company Stockholder Approval and (B) if it is reasonably necessary to obtain the Company Stockholder Approval, engage the services of a proxy solicitation agent. The Company Board shall recommend to the Company Stockholders that they provide the Company Stockholder Approval and shall include such recommendation in the Company Proxy Statement, except to the extent that the Company Board shall have made an Adverse Recommendation Change as permitted by Section 5.4. The Company agrees that its obligations pursuant to this Section 5.5 shall not be affected solely by either (i) the commencement, public proposal, public disclosure or communication to the Company of any Company Acquisition Proposal or (ii) the making of any Adverse Recommendation Change by the Company Board.

(e) The Company shall, prior to the Company Stockholders Meeting, keep Parent reasonably informed of the number of proxy votes received in respect of matters to be acted upon at the Company Stockholders Meeting, and in any event shall provide such number promptly upon the request of Parent or its Representatives.

(f) The Company shall not adjourn, postpone, delay or cancel (or propose for adjournment, postponement, delay or cancellation) the Company Stockholders Meeting without Parent's prior written consent; provided, that the Company shall be permitted to adjourn, postpone or delay the Company Stockholders Meeting without the prior consent of Parent if and to the extent that: (i) there are holders of an insufficient number of shares of Company Common Stock present or represented by a proxy at the Company Stockholders Meeting to constitute a quorum at the Company Stockholders Meeting, provided that any such adjournments, postponements or delays shall not cause the Company Stockholders Meeting to be reconvened on a date that is beyond the date that is 60 days from the date of the mailing of the Company Proxy Statement; (ii) the Company has not received proxies representing a sufficient number of shares of Company Common Stock to obtain the Company Stockholder Approval, provided that any such adjournments, postponements or delays shall not cause the Company Stockholders Meeting to be reconvened on a date that is beyond the date that is 60 days from the date of the mailing of the Company Proxy Statement; (iii) such adjournment, postponement, delay or cancellation is required by applicable Law or a request from the SEC or its staff; or (iv) in the good faith judgment of the Company Board (after consultation with its outside legal advisors), the failure to adjourn, postpone or delay the Company Stockholders Meeting could be reasonably likely to not allow sufficient time under applicable Laws for the distribution of any required or appropriate supplement or amendment to the Company Proxy Statement or the Parent Registration Statement.

(g) The Company will provide notice to Parent of the Company Stockholders Meeting and shall allow Representatives of Parent and its counsel to attend the Company Stockholders Meeting.

Section 5.6 Filings; Commercially Reasonable Efforts; Notification.

(a) Upon the terms and subject to the conditions of this Agreement, each of the Parties shall use commercially reasonable efforts to take, or cause to be taken, all actions, and to do, or cause to be done, and to assist and cooperate with the other Parties in doing, all things necessary, proper or advisable to consummate and make effective, as soon as practicable (but subject to Company's right to delay under Section 5.4 or Section 5.5(f)) and in any event prior to the End Date, the Transactions, including (i) obtaining and maintaining all necessary actions or nonactions, waivers, consents, licenses, permits, authorizations, orders and approvals (collectively, "Consents") from Governmental Authorities and the making of all other necessary registrations and filings, (ii) obtaining all Consents from third parties that are necessary or desirable in connection with the Transactions, (iii) the execution and delivery of any additional instruments necessary to consummate any of the Transactions, and to fully carry out the purposes of, this Agreement and (iv) providing all such information concerning such Party, its Subsidiaries and its Subsidiaries' officers, directors, employees and partners as may reasonably be requested in connection with any of the matters set forth in this Section 5.6. None of the Parties

will, and each will cause its Subsidiaries and controlled Affiliates not to, take any action or agree to take any action that would reasonably be expected to impose a request to file with Government Authorities or to impose any delay in the obtaining of, or materially increasing the risk of not obtaining, any required consent from any Government Authority, in each case with respect to the Transactions.

Without limiting the foregoing, Parent hereby agrees and covenants that the Parent shall, with respect to each taxable year of such holder during any part of which such holder held Parent Common Shares, (i) provide to such holder the information necessary to determine whether Parent is a PFIC and to make a QEF Election and any other election that may be available under applicable Law with respect to PFICs, and (ii) if a QEF Election is in effect for such holder for any taxable year, prepare and provide to such holder (which may be by posting on Parent's website) for submission to the U.S. Internal Revenue Service as provided in Treasury Regulations a "PFIC Annual Information Statement" as described in Section 1.1295-1(g)(1) of the Treasury Regulations or any successor regulation thereto. In addition, Parent shall provide information in its possession as may be reasonably necessary to assist any former holder of Company Common Stock in a determination of such holder's tax obligation in respect of any "excess distribution" under Section 1291 of the Code.

(b) Neither the Surviving Corporation nor Parent shall take, or omit to take, any action that would, or would reasonably be expected to cause Parent to be treated under the Law in effect as of any time after the Effective Time (including U.S. Internal Revenue Notice 2014-52, 2014-42 I.R.B. 712, except to the extent superseded, by U.S. Treasury Regulations or otherwise), as a result of the Transactions, as a "domestic corporation" within the meaning of the Code.

(c) Neither Parent nor any of its Subsidiaries shall cause either Intermediate Co. 1 or Intermediate Co. 2 to convert, merge, dissolve or liquidate under applicable Law.

Parent acknowledges and agrees that all elements of such Pre-Acquisition Actions must, as determined by the Company in its reasonable discretion:

(i) not impede, delay or prevent completion of the Merger;

(ii) be effective as close as reasonably practicable to the Closing Date;

(iii) not prejudice the Company, its Subsidiaries or its direct and indirect equityholders in any material respect;

(vii) not require the Company or any of its Subsidiaries to contravene any applicable Laws, the Company Organizational Documents, the Company Subsidiary Organizational Documents or any contract of the Company or its Subsidiaries;

(viii) not result in the treatment of the Company as other than a "domestic corporation" within the meaning of the Code;

(ix) not be a reportable transaction pursuant to Section 6011 of the Code or the Treasury Regulations promulgated thereunder;

(x) not result in any adverse financial, Tax or other consequence for the Company, its Subsidiaries or any of their direct or indirect equityholders for which they are not fully compensated for by Parent in each case; and

(xi) not become effective unless Parent and the Company shall have confirmed in writing that they are prepared promptly and without condition to proceed with the Merger.

(e) Parent will provide written notice to the Company of any requested Pre-Acquisition Action as soon as possible after the date hereof and in any event no less than 30 days prior to the Closing Date, together with a written step plan for the implementation of the requested Pre-Acquisition Action which shall set forth in reasonable detail (A) the requested steps to be undertaken, (B) the anticipated timing of the effectiveness or consummation of each such step, and (C) a list and description of all documentation and other acts necessary to give effect to each such step. Subject to Section 5.20(d), Section 5.20(f) and Section 5.20(g), the Company and Parent will, at the expense of Parent, work cooperatively and use commercially reasonable efforts to prepare prior to the Effective Time all documentation necessary and do such other acts and things as are necessary to give effect to such Pre-Acquisition Action. The Parties will seek to have the steps and transactions contemplated under any such Pre-Acquisition Action made effective at such times (as directed by Parent) prior to or on the Closing Date prior to the Effective Time (but if before the Effective Time, after the Parties have waived or confirmed that all conditions referred to in Sections 6.1, 6.2 and 6.3 have been satisfied, and the Parties have confirmed in writing that they are prepared to promptly proceed to effect the Merger without condition), Parent shall upon request by the Company advance all reasonable out-of-pocket expenses incurred by the Company or any of its Subsidiaries in connection with any actions taken by the Company or any of its Subsidiaries or, promptly upon request by the Company, reimburse the Company or its Subsidiaries for all reasonable fees and expenses (including any professional fees and expenses) and Taxes incurred by the Company and its Subsidiaries in connection with any Pre-Acquisition Action and shall indemnify the Company for any costs, Taxes, loss of opportunity or otherwise of the Company and its Subsidiaries in reversing or unwinding any Pre-Acquisition Action that was effected prior to the termination of this Agreement in accordance with its terms.

(f) Notwithstanding anything herein to the contrary, Parent shall be obligated to pay, and shall indemnify and hold harmless the Company and its Subsidiaries and direct and indirect equityholders and their respective Representatives (collectively the "Pre-Acquisition Action Indemnitees") from and against any and all out-of-pocket fees, expenses and costs and Taxes, liabilities, losses, damages, claims, costs, expenses, interest awards, judgments and penalties ("Damages") suffered or incurred by any of the Pre-Acquisition Indemnitees in connection with any actions taken, or cooperation, assistance with or participation, by any such Pre-Acquisition Action Indemnitee in connection with any Pre-Acquisition Action. All such Damages incurred in connection with any Pre-Acquisition Action requested by Parent remain payable by Parent even if the Pre-Acquisition Action does not close, or the Closing does not occur. No director, officer, employee or agent of the Company or any of its Subsidiaries shall be required, in connection with a Pre-Acquisition Action, to take any action in any capacity other than as a director, officer, employee or agent of the Company or its Subsidiaries, as the case may be.

(g) Notwithstanding anything to the contrary in this Agreement, in no event will completion of any Pre-Acquisition Action be a condition to completion of the Merger.
