W I T N E S S E T H:

WHEREAS, the Boards of Directors of Parent, US Corp., Merger Sub and the Company, and the managers of Merger LLC, have each determined that the transactions described herein are advisable and in the best interests of their respective companies and stockholders;

WHEREAS, in furtherance thereof, the respective Boards of Directors of Parent, US Corp., Merger Sub and the Company have approved and declared advisable this Agreement and the merger of Merger Sub with and into the Company (the “Merger”) in accordance with the applicable provisions of the General Corporation Law of the State of Delaware (the “DGCL”) and upon the terms and subject to the conditions set forth in this Agreement; and

WHEREAS, Parent, US Corp., Merger Sub, Merger LLC and the Company desire to make certain representations, warranties, covenants and agreements in connection with the Merger and also to prescribe various conditions to the Merger.

NOW, THEREFORE, in consideration of the foregoing and the representations, warranties, covenants and agreements contained herein, and intending to be legally bound hereby, Parent, US Corp., Merger Sub, Merger LLC and the Company agree as follows:

ARTICLE I

The Merger and the Subsequent Merger

SECTION 1.01. The Merger. On the terms and subject to the conditions set forth in this Agreement, and in accordance with the DGCL, Merger Sub shall be merged with and into the Company at the Effective Time. At the Effective Time, the separate corporate existence of Merger Sub shall cease and the Company shall continue as the surviving corporation (the “Surviving Corporation”). The Merger, the Subsequent Merger, the issuance by Parent of Parent Common Stock in connection with the Merger (the “Share Issuance”), the payment of cash consideration in connection with the Merger and the other transactions contemplated by this Agreement, other than the Financing, are referred to herein as the “Transactions”.

SECTION 1.02. Closing. The closing of the Merger (the “Closing”) shall take place at the offices of Sidley Austin LLP, ▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇, at 10:00 a.m. local time, no later than the third Business Day following the date (or, if Parent has not yet received the proceeds from the Financing, the date 10 Business Days following the date or such earlier date as Parent shall request on two (2) Business Days’ prior written notice to the

Company) on which each of the conditions set forth in Article VII is satisfied or, to the extent permitted by Law, waived by the party entitled to waive such condition (except for any conditions that by their nature can only be satisfied on the Closing Date, but subject to the satisfaction of such conditions or waiver by the party entitled to waive such conditions), or at such other time and place as Parent and the Company shall agree in writing. The date on which the Closing occurs is referred to herein as the “Closing Date”.

SECTION 1.03. Effective Time. On the Closing Date, the Company and Merger Sub shall file with the Secretary of State of the State of Delaware a certificate of merger or other appropriate documents (in any such case, the “Certificate of Merger”) duly executed in accordance with the relevant provisions of the DGCL and shall make all other filings or recordings required under the DGCL. The Merger shall become effective at such time as the Certificate of Merger is duly filed with such Secretary of State, or at such other time as Parent and the Company shall agree and specify in the Certificate of Merger (the time the Merger becomes effective being the “Effective Time”).

SECTION 1.04. Effects. The Merger shall have the effects set forth in this Agreement and Section 259 of the DGCL.

SECTION 1.05. Certificate of Incorporation and By-laws.

(a) At the Effective Time, the certificate of incorporation of Merger Sub, as in effect immediately prior to the Effective Time, shall be amended so as to read in its entirety as set forth on Exhibit A hereto. As so amended, the certificate of incorporation of Merger Sub shall be the certificate of incorporation of the Surviving Corporation until thereafter amended in accordance with the provisions thereof and hereof and applicable Law, in each case consistent with the obligations set forth in Section 6.06.

(b) At the Effective Time, the By-laws of Merger Sub as in effect immediately prior to the Effective Time shall be the By-laws of the Surviving Corporation until thereafter changed or amended as provided therein or by Law.

SECTION 1.06. Directors. The directors of Merger Sub immediately prior to the Effective Time shall be the directors of the Surviving Corporation, until the earlier of their resignation or removal or until their respective successors are duly elected and qualified, as the case may be.

SECTION 1.07. Officers. The officers of Merger Sub immediately prior to the Effective Time shall be the officers of the Surviving Corporation, until the earlier of their resignation or removal or until their respective successors are duly elected or appointed and qualified, as the case may be.

SECTION 1.08. Subsequent Merger.

(a) Provided that the opinions described in paragraph (c) below of this Section 1.08 are received on or prior to the Closing Date, immediately after the Effective Time Parent and US Corp. will cause the Surviving Corporation to merge with and into Merger LLC (the “Subsequent Merger”), the separate corporate existence of the Surviving Corporation shall

thereupon cease, Merger LLC shall continue as the surviving entity (the “Surviving Company”) and all of the rights and obligations of the Surviving Corporation under this Agreement shall be deemed the rights and obligations of the Surviving Company in accordance with the applicable provisions of the Limited Liability Company Act of the State of Delaware (the “LLC Act”). The Subsequent Merger shall have the effects set forth in Section 18-209(g) of the LLC Act.

(b) Provided that the opinions described in paragraph (c) below of this Section 1.08 are received on or prior to the Closing Date, the parties hereto intend that this Agreement will constitute a “plan of reorganization” with respect to the Merger and Subsequent Merger for United States federal income tax purposes pursuant to which, for such purposes, the Merger and the Subsequent Merger, taken together, are to be treated as a “reorganization” under Section 368(a) of the Internal Revenue Code of 1986 (the “Code”) (to which each of Parent, US Corp. and the Company are to be parties under Section 368(b) of the Code) in which the Company is to be treated as merging directly with and into US Corp., with the Company Common Stock converted in such merger into the right to receive the Merger Consideration provided for hereunder in a conversion to which Section 367(a)(1) of the Code does not apply.

(c) If, on or prior to the Closing Date, (i) the Company shall have received the opinion of Milbank, Tweed, ▇▇▇▇▇▇ & ▇▇▇▇▇▇ LLP, special counsel to the Company, dated as of the Closing Date, to the effect that the Merger and the Subsequent Merger, taken together, should be treated for U.S. federal income tax purposes as a “reorganization” within the meaning of Section 368(a) of the Code, that each of Parent, US Corp. and the Company will be a party to that reorganization within the meaning of Section 368(b) of the Code, and that, assuming the correctness of the foregoing conclusions, a conversion of Company Common Stock into the Merger Consideration provided for hereunder will be an exchange governed by Section 354 and Section 356 of the Code to which Section 367(a)(1) of the Code does not apply (the “Intended Tax Treatment”), and (ii) Parent shall have received the opinion of Sidley Austin LLP, special counsel to Parent, dated as of the Closing Date, to the effect that none of the Company, the Surviving Corporation, US Corp., Parent or Merger LLC will recognize income or gain for U.S. federal income tax purposes as a result of the Subsequent Merger, then the Subsequent Merger shall occur in accordance with Section 1.08(a) and each of the parties hereto shall, and shall cause its Affiliates to, treat the Merger, Subsequent Merger and the conversion of Company Common Stock into the Merger Consideration provided hereunder for all Tax purposes consistent with the Intended Tax Treatment. The opinions of counsel referred to above may be based on customary assumptions and representations, including representations of the Company and Parent. Each of the Company and Parent shall request its respective counsel to render an opinion to the effect described above. In the event that either party’s counsel is unable to render an opinion to the effect described above, such counsel shall (at the request of the other party) provide a written explanation of the substantive reason or reasons causing such counsel to be unable to do so. To the extent that either of such opinions is not received in accordance with the foregoing provisions of this Section 1.08(c), then the Subsequent Merger shall not occur and each of the parties hereto shall, and shall cause its respective Affiliates to, treat the Merger for U.S. federal income tax purposes as a taxable acquisition of the Company Common Stock by US Corp. in exchange for the Merger Consideration.

ARTICLE II

Effect on the Capital Stock of the

Constituent Corporations; Exchange of Certificates

SECTION 2.01. Effect on Capital Stock. At the Effective Time, by virtue of the Merger and without any action on the part of the holder of any shares of Company Common Stock or any shares of capital stock of Merger Sub:

(a) The issued and outstanding shares of capital stock of Merger Sub shall be converted into and become 14.4 million fully paid and nonassessable shares of Series A 5.9% Convertible Preferred Stock of the Surviving Corporation. In exchange for, and in consideration of, Parent delivering the shares of Parent Common Stock to be issued in the Merger to the Exchange Agent on behalf of US Corp. and Merger Sub in accordance with Section 2.02 and the payment by US Corp. to the Surviving Corporation of $10.00 (or such other amount as is agreed by US Corp. and the Surviving Corporation), the Surviving Corporation will issue to US Corp. 33.8 million fully paid and nonassessable shares (or such other number of shares as is agreed to by the Surviving Corporation and US Corp.) of common stock, par value $100.00 per share, of the Surviving Corporation.

(b) Each share of Company Common Stock that is owned by the Company, Parent, US Corp., Merger Sub, Merger LLC or any of their respective wholly-owned subsidiaries shall no longer be outstanding and shall automatically be cancelled and retired and shall cease to exist, and no Parent Common Stock or other consideration shall be delivered or deliverable in exchange therefor.

(c) At the Effective Time, by virtue of the Merger and without any action on the part of the Company, US Corp., Merger Sub, Merger LLC or the holders of any securities of the Company, US Corp., Merger Sub or Merger LLC:

(i) Subject to Sections 2.01(b), 2.01(c)(ii) and 2.01(d), each issued and outstanding share (other than shares to be cancelled in accordance with Section 2.01(b) and any Appraisal Shares (to the extent provided in Section 2.01(d))) of Company Common Stock shall automatically be converted into and shall thereafter represent the right to receive the combination of (x) $28.00 in cash without interest (the “Per Share Cash Amount”) and (y) 0.6606 of a validly issued, fully paid and nonassessable share of Parent Common Stock (subject to adjustment as provided in Section 2.01(c)(ii), the “Exchange Ratio”).

(ii) Notwithstanding anything in this Agreement to the contrary, if, from the date of this Agreement until the Effective Time, the outstanding shares of Parent Common Stock or Company Common Stock or the securities convertible into or exercisable for shares of Parent Common Stock or Company Common Stock shall have been changed into a different number of shares or a different class by reason of any reclassification, stock split (including a reverse stock split), recapitalization, split-up, combination, exchange of shares or readjustment, or a stock dividend thereon shall be declared with a record date within said period, the Per Share Cash Amount, the Exchange

Ratio and the Merger Consideration and any other similarly dependent items shall be appropriately adjusted to provide the holders of Company Common Stock the same economic effect as contemplated by this Agreement prior to such event.

(iii) The shares of Parent Common Stock to be issued, and cash payable, upon the conversion of shares of Company Common Stock pursuant to this Section 2.01(c) and cash in lieu of fractional shares of Parent Common Stock as contemplated by Section 2.02(e) are referred to collectively as “Merger Consideration”. As of the Effective Time, all such shares of Company Common Stock shall no longer be outstanding and shall automatically be cancelled and retired and shall cease to exist, and each holder of a certificate representing any such shares of Company Common Stock or Company Book-Entry Shares (either case being referred to in this Agreement, to the extent applicable, as a “Certificate”) shall cease to have any rights with respect thereto, except the right to receive, in accordance with Section 2.02, the Merger Consideration upon surrender of such Certificate, without interest.

(d) Notwithstanding anything in this Agreement to the contrary, shares (“Appraisal Shares”) of Company Common Stock that are outstanding immediately prior to the Effective Time and that are held by any Person who is entitled to demand and properly demands appraisal of such Appraisal Shares pursuant to, and who complies in all respects with, Section 262 of the DGCL (“Section 262”) shall not be converted into the Merger Consideration as provided in Section 2.01(c), but rather the holders of Appraisal Shares shall be entitled to payment by the Surviving Corporation of the fair market value of such Appraisal Shares in accordance with Section 262; provided, however, that if any such holder shall fail to perfect or otherwise shall waive, withdraw or lose the right to appraisal under Section 262, then the right of such holder to be paid the fair market value of such holder’s Appraisal Shares shall cease and such Appraisal Shares shall be deemed to have been converted as of the Effective Time into, and shall have become exchangeable solely for the right to receive, the Merger Consideration as provided in Section 2.01(c). The Company shall serve prompt written notice to Parent of any demands received by the Company for appraisal of any shares of Company Common Stock, and Parent shall have the right to participate in all negotiations and Proceedings with respect to such demands. Prior to the Effective Time, the Company shall not, without the prior written consent of Parent (not to be unreasonably withheld, delayed or conditioned), make any payment with respect to, or settle or offer to settle, any such demands, or agree to do any of the foregoing.

SECTION 2.02. Exchange of Certificates.

(a) Prior to the Effective Time, Parent (on behalf of US Corp. and Merger Sub) shall deposit with a nationally recognized financial institution designated by Parent (on behalf of US Corp. and Merger Sub) and reasonably acceptable to the Company (the “Exchange Agent”), for the benefit of the holders of shares of Company Common Stock whose shares are converted into the right to receive the Merger Consideration pursuant to this Article II, for exchange in accordance with this Article II, through the Exchange Agent, shares of Parent Common Stock (which shall be in non-certificated book entry form unless a physical certificate is requested) issuable pursuant to Section 2.01 in exchange for outstanding shares of Company Common Stock. Prior to the Effective Time, Merger Sub shall provide to the Exchange Agent all of the cash necessary to pay the cash portion of the aggregate Merger Consideration for the

shares of Company Common Stock converted into the right to receive the Merger Consideration pursuant to Section 2.01 and shall, after the Effective Time on the appropriate payment date, if applicable, provide or cause to be provided to the Exchange Agent any dividends or other distributions payable on such shares of Parent Common Stock pursuant to Section 2.02(c) (such shares of Parent Common Stock and cash provided to the Exchange Agent, together with any dividends or other distributions with respect thereto, being hereinafter referred to as the “Exchange Fund”). For the purposes of such deposit, Merger Sub shall assume that there will not be any fractional shares of Parent Common Stock. Merger Sub shall make available to the Exchange Agent, for addition to the Exchange Fund, from time to time as needed, cash sufficient to pay cash in lieu of fractional shares in accordance with Section 2.02(e). The Exchange Agent shall, pursuant to irrevocable instructions, deliver the Merger Consideration in accordance with this Section 2.02 out of the Exchange Fund. The Exchange Fund shall not be used for any other purpose.

(b) Parent (on behalf of US Corp. and Merger Sub) shall instruct the Exchange Agent to mail, as soon as reasonably practicable after the Effective Time, to each holder of record of a Certificate whose shares were converted into the right to receive the Merger Consideration pursuant to Section 2.01(c), (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 delivery of the Certificates to the Exchange Agent and shall be in such form and have such other provisions as Parent (on behalf of US Corp. and Merger Sub) may reasonably specify) and (ii) instructions for use in effecting the surrender of the Certificates in exchange for the Merger Consideration. Upon surrender of a Certificate for cancellation to the Exchange Agent or to such other agent or agents as may be appointed by Parent (on behalf of US Corp. and Merger Sub), together with such letter of transmittal, duly executed, and such other documents as may reasonably be required by the Exchange Agent, the holder of such Certificate shall be entitled to receive in exchange therefor (A) the Per Share Cash Amount with respect to which the aggregate number of shares of Company Common Stock previously represented by such Certificate shall have been converted pursuant to Section 2.01(c) into the right to receive, (B) the number of whole shares of Parent Common Stock (which shall be in non-certificated book entry form unless a physical certificate is requested) which the aggregate number of shares of Company Common Stock previously represented by such Certificate shall have been converted pursuant to Section 2.01(c) into the right to receive and (C) cash in lieu of fractional shares of Parent Common Stock as set forth in Section 2.02(e), and the Certificate so surrendered shall forthwith be cancelled. In the event of a transfer of ownership of Company Common Stock that is not registered in the transfer records of the Company, payment may be made and shares may be issued to a Person other than the Person in whose name the Certificate so surrendered is registered, if such Certificate shall be properly endorsed or otherwise be in proper form for transfer and the Person requesting such payment shall pay any transfer or other taxes required by reason of the payment to a Person other than the registered holder of such Certificate or establish to the satisfaction of Parent that such tax has been paid or is not applicable. Subject to the last sentence of Section 2.02(c), until surrendered as contemplated by this Section 2.02, each Certificate shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender the Merger Consideration into which the shares of Company Common Stock theretofore represented by such Certificate have been converted pursuant to Section 2.01(c). No interest shall be paid or accrue on any cash payable upon surrender of any Certificate.

(c) No dividends or other distributions with respect to Parent Common Stock with a record date after the Effective Time shall be paid to the holder of any certificate formerly representing Company Common Stock with respect to the shares of Parent Common Stock issuable upon surrender thereof, and no cash payment in lieu of fractional shares shall be paid to any such holder pursuant to Section 2.02(e), in each case until the surrender of such Certificate in accordance with this Article II. Subject to applicable Law, following surrender of any such Certificate, there shall be paid to the holder of the shares of Company Common Stock issued in exchange therefor, without interest, (i) at the time of such surrender, the amount of any cash payable in lieu of a fractional share of Parent Common Stock to which such holder is entitled pursuant to Section 2.02(e) and the amount of dividends or other distributions with a record date after the Effective Time theretofore paid with respect to such whole shares of Parent Common Stock 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 a payment date subsequent to such surrender payable with respect to such whole shares of Parent Common Stock.

(d) The Merger Consideration issued (and 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 issued (and paid) in full satisfaction of all rights pertaining to such shares of Company Common Stock. After the Effective Time 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 formerly representing shares of Company Common Stock are presented to the Surviving Corporation or the Exchange Agent for any reason, they shall be cancelled and exchanged as provided in this Article II.

(e) No certificates or scrip representing fractional shares of Parent Common Stock shall be issued upon the conversion of Company Common Stock pursuant to Section 2.01, and such fractional share interests shall not entitle the owner thereof to vote or to any rights of a holder of Parent Common Stock. For purposes of this Section 2.02(e), all fractional shares to which a single record holder would be entitled shall be aggregated and calculations shall be rounded to three decimal places. In lieu of any such fractional shares, each holder of Company Common Stock who would otherwise be entitled to such fractional shares shall be entitled to an amount in cash, without interest, rounded down to the nearest cent, equal to the product of (A) the amount of the fractional share interest in a share of Parent Common Stock to which such holder is entitled under Section 2.01(c) (or would be entitled but for this Section 2.02(e)) and (B) an amount equal to the average of the closing sale prices of the Parent Common Stock on Nasdaq for each of the five (5) trading days immediately prior to the Closing Date. As soon as practicable after the determination of the amount of cash, if any, to be paid to holders of Company Common Stock in lieu of any fractional share interests in Parent Common Stock, the Exchange Agent shall make available such amounts, without interest, to the holders of Company Common Stock entitled to receive such cash.

(f) Any portion of the Exchange Fund that remains undistributed to the holders of Company Common Stock for six months after the Effective Time shall be delivered to Parent (on behalf of the Surviving Corporation), upon demand, and any holder of Company Common Stock who has not theretofore complied with this Article II shall thereafter look only to Parent (on behalf of the Surviving Corporation) for payment of its claim for Merger Consideration and any dividends or distributions with respect to Parent Common Stock as contemplated by Section 2.02(c)(ii).

(g) None of Parent, US Corp., Merger Sub, Merger LLC, the Company, the Surviving Corporation, the Surviving Company or the Exchange Agent shall be liable to any Person in respect of any shares of Parent Common Stock (or dividends or distributions with respect thereto) or cash from the Exchange Fund (including any amounts delivered to Parent in accordance with Section 2.02(f)) delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law. If any Certificate has not been surrendered prior to five years after the Effective Time (or immediately prior to such earlier date on which Merger Consideration or any dividends or distributions with respect to Parent Common Stock as contemplated by Section 2.02(c)(i) in respect of such Certificate would otherwise escheat to or become the property of any Governmental Entity), any such shares, cash, dividends or distributions in respect of such Certificate shall, to the extent permitted by Law, become the property of the Surviving Corporation, free and clear of all claims or interest of any Person previously entitled thereto.

(h) In the event any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if required by Parent (on behalf of US Corp. and Merger Sub), the posting by such Person of a bond in customary amount as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Certificate the shares of Parent Common Stock and any cash, unpaid dividends or other distributions that would be payable or deliverable in respect thereof pursuant to this Agreement had such lost, stolen or destroyed Certificate been surrendered.

(i) The Exchange Agent shall invest any cash included in the Exchange Fund, as directed by Parent (on behalf of Merger Sub), on a daily basis; provided, however, that any investment of cash in the Exchange Fund shall in all events be limited to investment in direct short-term obligations of, or short-term obligations fully guaranteed as to principal and interest by, the United States government, or in funds investing solely in such obligations, and that no such investment or loss thereon shall affect the amounts payable to holders of Company Common Stock pursuant to Article II. Any interest and other income resulting from such investments shall be paid to Merger Sub. If for any reason (including losses) the Exchange Fund is inadequate to pay the amounts to which holders of shares of Company Common Stock shall be entitled under this Article II, Parent shall take all steps necessary to promptly deposit with the Exchange Agent additional Merger Consideration or other cash sufficient to make all payments required under this Agreement, and Parent shall in any event be liable for payment thereof.

(j) Parent (on behalf of Merger Sub) shall be entitled to deduct and withhold from the consideration otherwise payable in respect of the Transactions such amounts as may be required to be deducted and withheld with respect to the making of such payment under the Code, or under any provision of state, federal, provincial, territorial, local or foreign Tax Law. To the extent that amounts are so withheld and paid over to the appropriate taxing authority, such amounts shall be treated as paid to the Persons otherwise entitled to such amounts. If the amount withheld and paid over is in respect of consideration other than cash, the Surviving Corporation

or other payor will be treated as though it withheld an appropriate amount of the type of consideration otherwise payable to the Person entitled to such amount, sold such consideration on behalf of such Person for an amount of cash equal to the fair market value of such consideration at the time of such deemed sale and paid such cash proceeds to the appropriate taxing authority.

There are not any bonds, debentures, notes or other Indebtedness of the Company or any Company Subsidiary having the right to vote (or convertible into, or exchangeable or exercisable for, securities having the right to vote) on any matters on which holders of common stock of the

SECTION 3.03. Authority; Execution and Delivery; Enforceability; State Takeover Statutes.

(a) The Company has full power and authority to execute and deliver this Agreement, to perform and comply with each of its obligations under this Agreement and to consummate the Transactions. The execution and delivery by the Company hereof, the performance and compliance by the Company with each of its obligations herein and the consummation by the Company of the Transactions have been duly authorized by all necessary corporate action on the part of the Company, subject, in the case of the Merger, to receipt of the Company Stockholder Approval. The Company has duly executed and delivered this Agreement and, assuming the due authorization, execution and delivery by Parent, US Corp., Merger Sub and Merger LLC of this Agreement, this Agreement constitutes its legal, valid and binding obligation, enforceable against it in accordance with its terms, except as limited by Laws affecting the enforcement of creditors’ rights generally, by general equitable principles or by the discretion of any Governmental Entity before which any Proceeding seeking enforcement may be brought.

best interests of the Company and its stockholders (the “Company Determination”), (iii) directing that this Agreement be submitted to the stockholders of the Company for adoption and approval, (iv) recommending that the Company’s stockholders adopt this Agreement and (v) declaring that this Agreement and the Merger are advisable. Unless a Company Adverse Recommendation Change has occurred in accordance with Section 5.02(e) or 5.02(f), such resolutions remain in full force and effect and have not been modified, rescinded, amended or withdrawn. Such resolutions are sufficient to render inapplicable to this Agreement, the Merger, the Subsequent Merger and the other Transactions the provisions of Section 203 of the DGCL (“Section 203”). No other “business combination,” “control share acquisition,” “fair price,” “moratorium” or other anti-takeover Laws (collectively, “Takeover Laws”) apply or purport to apply to this Agreement, the Merger, the Subsequent Merger or any other Transaction.

(c) The only vote of holders of any class or series of Company Capital Stock or of any other securities of the Company necessary to approve and adopt this Agreement, the Merger and the Subsequent Merger is the approval and adoption of this Agreement by the holders of a majority of the issued and outstanding shares of Company Common Stock entitled to vote thereon (the “Company Stockholder Requisite Vote”).

SECTION 3.04. No Conflicts; Consents.

(b) No consent, approval, waiver, license, permit, franchise, authorization or Judgment (“Consent”) of, or registration, declaration, notice, report, submission or other filing (“Filing”) with, any Governmental Entity is required to be obtained or made by or with respect to the Company or any Company Subsidiary in connection with the execution, delivery and performance hereof or the consummation of the Transactions or the ownership by Parent of the Surviving Corporation following the Closing, other than (i) compliance with, and Filings under,

the ▇▇▇▇-▇▇▇▇▇-▇▇▇▇▇▇ Antitrust Improvements Act of 1976 (the “HSR Act”) and any Filings required under other applicable Regulatory Laws, (ii) the filing with the SEC of (A) the registration statement on Form S-4 in connection with the Share Issuance (together with any amendment or supplements thereto, the “Form S-4”) and the Joint Proxy Statement and (B) such reports under the Exchange Act as may be required in connection with this Agreement, the Merger, the Subsequent Merger, the other Transactions, (iii) such Filings as are required under US state securities or “blue sky” Laws or securities Laws of jurisdictions other than the United States, (iv) the filing of the Certificate of Merger and the filing of the certificate of merger in connection with the Subsequent Merger, in each case with the Secretary of State of the State of Delaware, and (v) such other Consents and Filings the failure of which to obtain or make has not had and would not reasonably be expected to have, individually or in the aggregate, a Company Material Adverse Effect or materially impair the ability of the Company to perform its obligations hereunder or prevent or unreasonably delay the consummation of any of the Transactions.

SECTION 3.05. SEC Documents; Undisclosed Liabilities.

(a) The Company has filed or furnished all reports, schedules, forms, statements and other documents required to be filed or furnished by the Company with the SEC under the Securities Act or the Exchange Act since December 31, 2011 (the “Company SEC Documents”).

Based on the Company’s management’s most recently completed evaluation of the Company’s internal control over financial reporting prior to the date of this Agreement, (i) the Company had no significant deficiencies or material weaknesses in the design or operation of its internal control over financial reporting that would reasonably be expected to adversely affect the Company’s ability to record, process, summarize and report financial information and (ii) the Company does not have knowledge of any fraud, whether or not material, that involves management or other employees who have a significant role in the Company’s internal control over financial reporting.

shall include the information with respect to such Superior Company Proposal that is specified in Section 5.02(b) (it being agreed that neither the delivery of such notice by the Company nor any public announcement thereof that the Company Board determines that it is required to make under applicable Law shall constitute a Company Adverse Recommendation Change unless and until the Company shall have failed at or prior to the end of the period referred to in clause (v) below (and, upon the occurrence of such failure, such notice and such public announcement shall constitute a Company Adverse Recommendation Change) to publicly announce that the Company Board (A) was expressly reaffirming the Company Recommendation and Company Determination and (B) has determined that such other Company Takeover Proposal (after taking into account any modifications or adjustments made to this Agreement, the Financing Letter, the Financing and the Transactions and agreed to by the parties hereto and any modifications or adjustments made to such other Company Takeover Proposal) is not a Superior Company Proposal and has publicly rejected such Company Takeover Proposal); (v) during such five (5) Business Day period, the Company and its Representatives have negotiated in good faith with Parent regarding any revisions to the terms of this Agreement, the Financing Letter, the Financing and the Transactions proposed by Parent in response to such Superior Company Proposal; (vi) at the end of the five (5) Business Day period described in the foregoing clause (v) (and taking into account any adjustment or modification of the terms of this Agreement, the Financing Letter, the Financing and the Transactions proposed by Parent) the Company Takeover Proposal continues to be a Superior Company Proposal and the Company Board concludes in good faith, after consultation with its outside legal counsel and financial advisors that the failure to make a Company Adverse Recommendation Change would be inconsistent with the exercise by the Company Board of its fiduciary duties to the stockholders of the Company under applicable Laws; and (vii) concurrently with the termination of this Agreement, the Company pays Parent the Company Termination Fee. Any material amendment or modification to any Superior Company Proposal (it being understood and agreed that any change in the consideration to be received is a material modification) will be deemed to be a new Company Takeover Proposal for purposes of this Section 5.02; provided, however, that with respect to each and every material amendment or modification, the notice period and the period during which the Company and its Representatives are required to negotiate in good faith with Parent regarding any revisions to the terms of this Agreement, the Financing Letter, the Financing and the Transactions pursuant to clause (v) above shall expire on the second (2^nd) Business Day after the Company Board provides written notice of such new Company Takeover Proposal to Parent.

shall constitute a Company Adverse Recommendation Change unless and until the Company shall have failed at or prior to the end of the period referred to in clause (iii) below (and, upon the occurrence of such failure, such notice and such public announcement shall constitute a Company Adverse Recommendation Change) to publicly announce that the Company Board (A) was expressly reaffirming the Company Recommendation and the Company Determination and (B) has determined that such Company Intervening Event (after taking into account any modifications or adjustments made to this Agreement, the Financing Letter, the Financing and the Transactions and agreed to by the parties hereto) no longer exists); (iii) during such five (5) Business Day period, the Company and its Representatives have negotiated in good faith with Parent regarding any revisions to the terms of this Agreement, the Financing Letter, the Financing and the Transactions proposed by Parent in response to such Company Intervening Event; and (iv) at the end of the five (5) Business Day period described in the foregoing clause (iii), the Company Board again concludes in good faith, after consultation with its outside legal counsel (and taking into account any adjustment or modification of the terms of this Agreement, the Financing Letter, the Financing and the Transactions proposed by Parent), that a Company Intervening Event continues to exist and that the failure to make a Company Adverse Recommendation Change would be inconsistent with the exercise by the Company Board of its fiduciary duties to the stockholders of the Company under applicable Laws.

(g) During the period from the date of this Agreement through the earlier of the Effective Time and the date of termination of this Agreement, the Company shall not terminate, amend, modify or waive any provision of any confidentiality agreement relating to a Company Takeover Proposal or standstill agreement to which the Company or any of the Company Subsidiaries is a party (other than any involving Parent).

(e) Notwithstanding anything in this Agreement to the contrary, in response to a Parent Takeover Proposal, the Parent Board may at any time prior to receipt of Parent Stockholder Approval, effect a Parent Adverse Recommendation Change, and, subject to compliance with the requirements of this Section 5.03(e) and Section 6.07(e), terminate this Agreement in order to concurrently enter into a binding definitive agreement to effect a Superior Parent Proposal, if (and only if): (i) a written Parent Takeover Proposal that was not solicited in violation of Section 5.03(a) is made to Parent by a Third Party and such Parent Takeover Proposal is not withdrawn and Parent has complied with this Section 5.03 in all material respects; (ii) such Parent Takeover Proposal constitutes a Superior Parent Proposal; (iii) the Parent Board concludes in good faith, after consultation with its outside legal counsel, that the failure to make a Parent Adverse Recommendation Change would be inconsistent with the exercise of its fiduciary duties to the stockholders of Parent under applicable Laws; (iv) Parent provides the Company at least five (5) Business Days’ prior written notice of the Parent Board’s intention to take such action, which notice shall include the information with respect to such Superior Parent Proposal that is specified in Section 5.03(b) (it being agreed that neither the delivery of such notice by Parent nor any public announcement thereof that the Parent Board determines that it is required to make under applicable Law shall constitute a Parent Adverse Recommendation Change unless and until Parent shall have failed at or prior to the end of the period referred to in clause (v) below (and, upon the occurrence of such failure, such notice and such public announcement shall constitute a Parent Adverse Recommendation Change) to publicly announce that the Parent Board (A) was expressly reaffirming the Parent Recommendation and Parent Determination and (B) has determined that such other Parent

Takeover Proposal (after taking into account any modifications or adjustments made to this Agreement and the Transactions and agreed to by the parties hereto and any modifications or adjustments made to such other Parent Takeover Proposal) is not a Superior Parent Proposal and has publicly rejected such Parent Takeover Proposal); (v) during such five (5) Business Day period, Parent and its Representatives have negotiated in good faith with the Company regarding any revisions to the terms of this Agreement and the Transactions proposed by the Company in response to such Superior Parent Proposal; (vi) at the end of the five (5) Business Day period described in the foregoing clause (v) (and taking into account any adjustment or modification of the terms of this Agreement and the Transactions proposed by the Company) the Parent Takeover Proposal continues to be a Superior Parent Proposal and the Parent Board concludes in good faith, after consultation with its outside legal counsel and financial advisors that the failure to make a Parent Adverse Recommendation Change would be inconsistent with the exercise by the Parent Board of its fiduciary duties to the stockholders of Parent under applicable Laws; and (vii) concurrently with the termination of this Agreement, Parent pays to the Company the Parent Termination Fee. Any material amendment or modification to any Superior Parent Proposal (it being understood and agreed that any change in the consideration to be received is a material modification) will be deemed to be a new Parent Takeover Proposal for purposes of this Section 5.03; provided, however, that with respect to each and every material amendment or modification, the notice period and the period during which Parent and its Representatives are required to negotiate in good faith with the Company regarding any revisions to the terms of this Agreement and the Transactions pursuant to clause (v) above shall expire on the second (2^nd) Business Day after the Parent Board provides written notice of such new Parent Takeover Proposal to the Company.

(f) Nothing in this Agreement shall prohibit or restrict the Parent Board, in circumstances not involving or relating to a Parent Takeover Proposal, from effecting prior to obtaining the Parent Stockholder Approval a Parent Adverse Recommendation Change of the type described in clause (A) of the definition thereof in response to the occurrence of a Parent Intervening Event, if (and only if): (i) the Parent Board concludes in good faith, after consultation with its outside legal counsel, that the failure to take such action would be inconsistent with the exercise of its fiduciary duties to the stockholders of Parent under applicable Laws; (ii) Parent provides the Company at least five (5) Business Days’ prior written notice describing Parent Intervening Event and advising the Company that the Parent Board intends to take such action and specifying the reasons therefor in reasonable detail (it being agreed that neither the delivery of such notice by Parent nor any public announcement thereof that the Parent Board determines that it is required to make under applicable Law shall constitute a Parent Adverse Recommendation Change unless and until Parent shall have failed at or prior to the end of the period referred to in clause (iii) below (and, upon the occurrence of such failure, such notice and such public announcement shall constitute a Parent Adverse Recommendation Change) to publicly announce that the Parent Board (A) was expressly reaffirming the Parent Recommendation and Parent Determination and (B) has determined that such Parent Intervening Event (after taking into account any modifications or adjustments made to this Agreement and the Transactions and agreed to by the parties hereto) no longer exists); (iii) during such five (5) Business Day period, Parent and its Representatives have negotiated in good faith with the Company regarding any revisions to the terms of this Agreement and the Transactions proposed by the Company in response to such Parent Intervening Event; and (iv) at the end of the five (5) Business Day period described in the foregoing clause (iii), the Parent Board again concludes in

good faith, after consultation with its outside legal counsel (and taking into account any adjustment or modification of the terms of this Agreement and the Transactions proposed by the Company), that a Parent Intervening Event continues to exist and that the failure to make a Parent Adverse Recommendation Change would be inconsistent with the exercise by the Parent Board of its fiduciary duties to the stockholders of Parent under applicable Laws.

(g) During the period from the date of this Agreement through the earlier of the Effective Time and the date of termination of this Agreement, Parent shall not terminate, amend, modify or waive any provision of any confidentiality agreement relating to a Parent Takeover Proposal or standstill agreement to which Parent or any of the Parent Subsidiaries is a party (other than any involving the Company). During such period, Parent agrees to enforce, to the fullest extent permitted under applicable Law, the provisions of any such agreements, including obtaining injunctions to prevent any breaches of such agreements and to enforce specifically the terms and provisions thereof in any court of the United States or any state thereof having jurisdiction.

(h) Nothing contained in this Section 5.03 shall prohibit the Parent Board from (i) taking and disclosing to the stockholders of Parent a position contemplated by Rule 14e-2(a) promulgated under the Exchange Act or making a statement contemplated by Item 1012(a) of Regulation M-A or Rule 14d-9 promulgated under the Exchange Act or (ii) making any disclosure to the stockholders of Parent if the Parent Board determines in good faith, after consultation with its outside counsel, that the failure to make such disclosure would reasonably be determined to be inconsistent with applicable Law; provided, however, that (A) any disclosure of a position contemplated by Rule 14e-2(a) or Rule 14d-9 promulgated under the Exchange Act other than a “stop, look and listen” or similar communication of the type contemplated by Rule 14d-9(f) under the Exchange Act, an express rejection of any applicable Parent Takeover Proposal or an express reaffirmation of the Parent Recommendation, shall be deemed to be a Parent Adverse Recommendation Change and (B) neither Parent nor the Parent Board (nor any committee thereof) shall make any Parent Adverse Recommendation Change except in accordance with the other provisions of this Section 5.03.

(i) Certain Definitions. For purposes of this Agreement:

“Parent Acquisition Transaction” means any transaction or series of related transactions other than the Merger, the Subsequent Merger or any transaction permitted pursuant to item 8 of Section 5.01(b) of the Parent Disclosure Letter involving: (i) any acquisition or purchase by any Third Party of more than 20% of the total outstanding voting securities of Parent or any of the Parent Subsidiaries; (ii) any tender offer or exchange offer that if consummated would result in any Third Party beneficially owning more than 20% of the total outstanding voting securities of Parent or any of the Parent Subsidiaries; (iii) any merger, amalgamation, plan of arrangement, consolidation, business combination, share exchange, recapitalization or similar transaction involving Parent or any Parent Subsidiary pursuant to which the stockholders of Parent immediately preceding such transaction hold less than 80% of the equity interests in the surviving or resulting entity of such transaction; (iv) any direct or indirect acquisition of any business or businesses or of assets (including equity interests in any Parent Subsidiary) that constitute or account for 20% or more of the consolidated net revenues, net income or assets (based on the fair market value thereof) of Parent and the Parent Subsidiaries, taken as a whole; or (v) any liquidation or dissolution of Parent or any of the Parent Subsidiaries.

“Superior Parent Proposal” means an unsolicited, bona fide written Parent Takeover Proposal to acquire more than (i) 50% of the outstanding voting securities of Parent or (ii) 50% of the consolidated assets of Parent and the Parent Subsidiaries, in either case on terms that, in the good faith judgment of the Parent Board, after consultation with its outside financial advisors and its outside legal counsel, taking into account relevant legal, financial and regulatory aspects of the proposal, the identity of the Third Party making such proposal and the conditions for completion of such proposal (A) is more favorable, from a financial point of view, to the stockholders of Parent than the Merger and the Subsequent Merger, taken together, taking into account all of the terms and conditions of such proposal and this Agreement (including any changes to the terms of this Agreement proposed by the Company in response to such proposal or otherwise), and (B) is reasonably capable of being completed on the terms set forth in the proposal, taking into account all financial, legal, regulatory and other aspects thereof.

If at any time prior to the Effective Time any information relating to Parent or the Company, or any of their respective Affiliates, officers or directors, is discovered by Parent or the Company which should be set forth in an amendment or supplement to any of the Form S-4 or the Joint Proxy Statement, so that any of such documents would not include any misstatement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, the party which 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 applicable Canadian securities regulatory authorities, after the other party has had a reasonable opportunity to review and comment thereon, and, to the extent required by applicable Law, disseminated to the respective stockholders of Parent and the Company. Parent will cause the Joint Proxy Statement to be filed as required by applicable securities Laws and mailed to Parent’s stockholders, and the Company will cause the Joint Proxy Statement to be mailed to the Company’s stockholders, in each case as promptly as reasonably practicable after the Form S-4 is declared effective under the Securities Act.

(b) The Company shall, as soon as practicable following effectiveness of the Form S-4, duly call, give notice of, convene and hold a meeting of its stockholders (the “Company Stockholders Meeting”) for the purpose of seeking and obtaining the adoption of this Agreement by the stockholders of the Company by the Company Stockholder Requisite Vote (the “Company Stockholder Approval”) and the approval of the Merger. Subject to Sections 5.02(e) and 5.02(f), the Company shall, through the Company Board, recommend that its stockholders adopt and approve this Agreement and the Merger (the “Company Recommendation”), and shall use reasonable best efforts to (i) solicit from its stockholders proxies in favor of the approval and adoption of this Agreement and the Merger, and (ii) take all other action necessary or advisable to secure the Company Stockholder Approval and the Company Board shall not effect a Company Adverse Recommendation Change. Notwithstanding any Company Adverse Recommendation Change, unless this Agreement is terminated in accordance with its terms, (A) the obligations of the parties hereunder, including the obligations of the Company in the first sentence of this Section 6.01(b), shall continue in full force and effect and (B) the Company shall continue to take all actions necessary to render inapplicable to this Agreement and the Transactions Section 203 and all other Takeover Laws.

(c) Parent shall, as soon as practicable following effectiveness of the Form S-4, duly call, give notice of, convene and hold a meeting of its stockholders (the “Parent Stockholders Meeting”) for the purpose of seeking the Parent Stockholder Approval. Subject to Sections 5.03(e) and 5.03(f), Parent shall, through the Parent Board, recommend that its stockholders approve the Share Issuance (the “Parent Recommendation”), and shall use

reasonable best efforts to (i) solicit from its stockholders proxies in favor of the Share Issuance and (ii) take all other action necessary or advisable to secure the Parent Stockholder Approval and the Parent Board shall not effect a Parent Adverse Recommendation Change. Notwithstanding any Parent Adverse Recommendation Change, unless this Agreement is terminated in accordance with its terms, (A) the obligations of the parties hereunder, including the obligations of Parent in the first sentence of this Section 6.01(c), shall continue in full force and effect and (B) Parent shall continue to take all actions necessary to render inapplicable to this Agreement all Takeover Laws.

(d) Each of the Company and Parent will use reasonable best efforts to hold the Company Stockholders Meeting and the Parent Stockholders Meeting, respectively, on the same date as the other party and as soon as reasonably practicable after the effectiveness of the Form S-4.

SECTION 6.02. Access to Information; Confidentiality. Subject to contractual and legal restrictions applicable to Parent or the Company or any of their respective subsidiaries with respect to the exchange of information, each of the Company and Parent shall, and shall cause each of its respective subsidiaries to, afford to the other party and to the Representatives of such other party, reasonable access during normal business hours during the period prior to the Effective Time or the termination of this Agreement to all their respective properties, books, contracts, commitments, personnel and records (including the work papers of independent accountants, if available, and subject to the consent of such independent accountants), including for purposes of Parent and its Representatives, to conduct audits from time to time of the Company’s and the Company Subsidiaries’ practices and procedures pursuant to Medicare, Medicaid and any other federal health care program (as such term is defined in 42 U.S.C. §1320a-7b(f)) activities, and, during such period, each of the Company and Parent shall, and shall cause each of its respective subsidiaries to, furnish promptly to the other party (a) a copy of each report, schedule, registration statement and other document filed by it during such period pursuant to the requirements of federal or state securities Laws and (b) all other information concerning its business, properties and personnel as such other party may reasonably request; provided, however, that such access does not unreasonably disrupt the normal operations of the Company and the Company Subsidiaries, or Parent and the Parent Subsidiaries, as applicable. No investigation pursuant to this Section 6.02 shall affect any representation or warranty in this Agreement of any party hereto or any condition to the obligations of the parties hereto. This Section 6.02 shall not require the Company or any Company Subsidiary, or Parent or any Parent Subsidiary, to permit any access, or to disclose any information, that in the reasonable judgment of such party, would reasonably be expected to result in (i) the disclosure of any trade secrets of Third Parties or a violation of any of its obligations with respect to confidentiality if such party shall have used its reasonable best efforts to obtain the consent of such Third Party to such inspection or disclosure, (ii) the loss of attorney-client privilege with respect to such information (iii) in the case of documents or portions of documents relating to pricing or other matters that are highly sensitive, a Governmental Entity alleging that providing such information violates any Regulatory Law or (iv) a violation of applicable privacy Laws. If any material is withheld by such party pursuant to the preceding sentence, such party shall inform the other party as to the general nature of what is being withheld. All information exchanged pursuant to this Section 6.02 shall be subject to the Confidentiality Agreement.

SECTION 6.03. Commercially Reasonable Efforts; Notification.

(a) Subject to the terms and conditions set forth in this Agreement, each of the parties shall use its commercially reasonable efforts (subject to, and in accordance with, applicable Law), to take promptly, or cause to be taken, all actions, and to do promptly, or cause to be done, and to assist and cooperate with the other parties in doing, all things necessary, proper or advisable under applicable Laws to consummate and make effective the Merger, the Subsequent Merger and the other Transactions, including (i) the obtaining of all necessary actions or nonactions and Consents from Governmental Entities, Nasdaq and the TSX and the making of all necessary registrations and Filings and the taking of all steps as may be necessary to obtain an approval or waiver from, or to avoid a Proceeding by, any Governmental Entity, Nasdaq or the TSX, (ii) the obtaining of all necessary Consents from Third Parties, and (iii) the execution and delivery of any additional instruments necessary to consummate the Transactions; provided, however, that in no event shall Parent, US Corp., Merger Sub, Merger LLC or the Company or any of their respective subsidiaries be required to (and in no event shall the Company or any Company Subsidiary without the prior written consent of Parent) pay any fee, penalty or other consideration to any Third Party or make any other concession to any Third Party for any Consent required for the consummation of the Transactions under any Contract.

(b) Subject to the terms and conditions herein provided and without limiting the foregoing, the Company and Parent shall (i) to the extent required, (A) promptly, but in no event later than ten Business Days after the date hereof, make their respective Filings under the HSR Act and (B) as promptly as reasonably practicable after the date hereof, make any other required submissions under the HSR Act (which submissions shall be in substantial compliance with the requirements of the HSR Act and any other applicable Law), (ii) use commercially reasonable efforts to cooperate with each other in (A) determining whether any Filings are required to be made with, or Consents are required to be obtained from, any Third Parties or other Governmental Entities in connection with the execution and delivery of this Agreement and the consummation of the Transactions and (B) timely making all such Filings (which Filings shall be in substantial compliance with the requirements of applicable Law) and timely seeking all such Consents and (iii) use commercially reasonable efforts to take, or cause to be taken, all other actions and do, or cause to be done, all other things necessary, proper or advisable to consummate and make effective the Transactions, including taking all such further action as may be necessary to resolve such objections, if any, as the United States Federal Trade Commission, the Antitrust Division of the United States Department of Justice, state antitrust enforcement authorities or competition authorities of any other nation or other jurisdiction or any other Governmental Entity may assert under Regulatory Law with respect to the Transactions. Notwithstanding anything in this Agreement to the contrary, in no event shall Parent be required to (and in no event shall the Company or any Company Subsidiary agree to without the prior written consent of Parent) divest any assets or agree to divest any assets or consent to or take any other action or agree to any limitation or make any concession or other undertaking which would individually, or together with all other such divestitures, agreements, consents, actions, limitations or concessions, be reasonably likely to materially and adversely affect (x) the benefits expected to be derived by Parent as a result of the Merger and the Subsequent Merger, taken together, (y) the business of Parent and the Parent Subsidiaries or of the Company and the Company Subsidiaries, in each case as currently conducted, or (z) the business of the Company and the Company Subsidiaries as contemplated to be conducted on a combined basis with Parent

and the Parent Subsidiaries following the Merger and the Subsequent Merger (any such requirement, individually or together with all other such requirements, a “Burdensome Regulatory Action”). Subject to applicable legal limitations and the instructions of any Governmental Entity, the Company and Parent shall keep each other apprised of the status of matters relating to the completion of the Transactions, including promptly furnishing the other with copies of notices or other communications received by the Company or Parent, as the case may be, or any of their respective subsidiaries, from any Third Party and/or any Governmental Entity with respect to such transactions. The Company and Parent shall permit counsel for the other party reasonable opportunity to review in advance, and consider in good faith, the views of the other party in connection with, any proposed written communication to any Governmental Entity. Each of the Company and Parent agrees, to the extent reasonably feasible, not to participate in any meeting or discussion (other than relating to non-substantive matters such as the scheduling of any meetings or of any discussions), either in person or by telephone, with any Governmental Entity in connection with the proposed transactions unless it consults with the other party in advance and, to the extent not prohibited by such Governmental Entity, gives the other party the opportunity to attend and participate. The Company and Parent shall furnish the other with such necessary information and reasonable assistance as the other may reasonably request in connection with its preparation of necessary Filings or submissions of information to any Governmental Entity. Subject to applicable Laws relating to the exchange of information, Parent or the Company shall have the right to direct all matters with any Governmental Entity consistent with its obligations hereunder. Either Parent or the Company may designate any competitively sensitive information provided to the other under this Agreement as “outside counsel only”. Such materials and the information contained therein shall be given only to outside legal counsel of the other and will not be disclosed by such outside counsel to employees, officers or directors of their client unless express written permission is obtained in advance from the disclosing party or its legal counsel.

(c) In furtherance and not in limitation of the covenants of the parties contained in this Section 6.03, if any Proceeding, including any Proceeding by a private party, is instituted (or threatened to be instituted) challenging any Transaction as violative of any Regulatory Law, each of the Company and Parent shall cooperate in all respects with each other and shall use their respective commercially reasonable efforts to contest and resist any such Proceeding and to have vacated, lifted, reversed or overturned any Judgment that is in effect and that prohibits, prevents or restricts consummation of the Transactions. Notwithstanding the foregoing or any other provision of this Agreement, nothing in this Section 6.03 shall limit a party’s right to terminate this Agreement pursuant to Section 8.01(b)(i) or 8.01(b)(ii).

(d) The obligations of Parent, US Corp., Merger Sub and Merger LLC with respect to obtaining the Financing shall be governed by Section 6.12 and not this Section 6.03.

SECTION 6.04. Treatment of Company Stock Options, Unvested Company Shares, Company Stock Purchase Plan and Company Warrants.

(a) At the Effective Time, if Parent so elects, Parent may assume any or all of the Company Stock Plans or merge any such Company Stock Plan into any Parent Stock Plan. If Parent elects to so assume or merge any Company Stock Plan, then, under such Company Stock Plan, Parent shall be entitled to grant stock awards, to the extent permissible under applicable

requirements of Law, using the share reserves of such Company Stock Plan as of the Effective Time (including any shares returned to such share reserves as a result of the termination of any option to purchase Company Common Stock (each, a “Company Stock Option”) that is unvested immediately prior to the Effective Time and that is assumed or replaced by Parent pursuant to Section 6.04(b)), except that: (i) stock covered by such awards shall be shares of Parent Common Stock; (ii) all references in such Company Stock Plan to a number of shares of Company Common Stock shall be deemed amended to refer instead to a number of shares of Parent Common Stock determined by multiplying the number of referenced shares of Company Common Stock by the Exchange Ratio, and rounding the resulting number down to the nearest whole number of shares of Parent Common Stock; and (iii) the Parent Board or a committee thereof shall succeed to the authority and responsibility of the Company Board or any committee thereof with respect to the administration of such Company Stock Plan.

(b) At the Effective Time, each Company Stock Option that is outstanding immediately prior to the Effective Time pursuant to the Company Stock Plans shall, to the extent permitted by the terms of the applicable Company Stock Plan, be assumed by Parent and become and represent an option to purchase the number of shares of Parent Common Stock (a “Parent Stock Option”) (decreased to the nearest full share) determined by multiplying (i) the number of shares of Company Common Stock subject to such Company Stock Option immediately prior to the Effective Time by (ii) the Option Exchange Ratio (as hereinafter defined), at an exercise price per share of Parent Common Stock (rounded up to the nearest cent) equal to the exercise price per share of Company Common Stock under such Company Stock Option immediately prior to the Effective Time divided by the Option Exchange Ratio. After the Effective Time, except as provided above in this Section 6.04(b), each Parent Stock Option shall be exercisable upon the same terms and conditions as were applicable under the related Company Stock Option immediately prior to the Effective Time, after giving effect to any acceleration, lapse or other vesting occurring by operation of the Merger. The Company shall take all necessary action to implement and make effective the provisions of this Section 6.04(b). For purposes of this Agreement, the “Option Exchange Ratio” means the sum of (A) the Exchange Ratio plus (B) a ratio, the numerator of which is the Per Share Cash Amount and the denominator of which is the average of the last reported sale price per share of Parent Common Stock on Nasdaq on each of the five (5) trading days immediately preceding the Effective Time.

(c) Immediately prior to the Effective Time, all Unvested Share Restrictions (as hereinafter defined), including all repurchase and forfeiture rights held by the Company, shall lapse and the Unvested Company Shares shall become fully vested shares of Company Common Stock. Such shares of Company Common Stock shall be cancelled in exchange for the right to receive the Merger Consideration in accordance with Section 2.01. For purposes of this Agreement, (i) “Unvested Company Share” means each outstanding share of Company Common Stock issued under a Company Stock Plan or otherwise which is subject to any Unvested Share Restrictions other than shares of Company Common Stock subject to Company PSU Awards (as defined below), and (ii) “Unvested Share Restrictions” means all repurchase, cancellation, forfeiture, vesting and other conditions or restrictions applicable to an Unvested Company Share. The Company shall take all necessary action to implement and make effective the provisions of this Section 6.04(c).

(d) Immediately prior to the Effective Time, each award of performance share units with respect to shares of Company Common Stock granted under a Company Stock Plan (collectively, the “Company PSU Awards”) which is outstanding immediately prior to the Effective Time shall become fully vested at 100% of the target number of performance share units subject to such Company PSU Award. Such Company PSU Awards shall be cancelled in exchange for the right to receive the Merger Consideration in accordance with Section 2.01.

(e) Prior to the Effective Time, the Company shall take all necessary action for the adjustment of Company Stock Options, Unvested Company Shares and Company PSU Awards under this Section 6.04. As soon as practicable following the Effective Time, Parent shall file a registration statement on Form S-8 (or other applicable form) with respect to the shares of Parent Common Stock subject to all such awards.

(f) The Company shall take all action necessary under the Company’s 2004 Employee Stock Purchase Plan (the “Company Stock Purchase Plan”) to provide that: (i) no new Offering (as defined in the Company Stock Purchase Plan) shall commence after the date of this Agreement; (ii) all options under the Company Stock Purchase Plan outstanding as of the date of this Agreement shall be exercised, to the extent of any accumulated payroll deductions as of the exercise date, on the earlier to occur of (A) the end of the Plan Period (as defined in the Company Stock Purchase Plan) pending as of the date of this Agreement and (B) a date that is at least five (5) Business Days prior to the Effective Time; and (iii) the Company Stock Purchase Plan shall be terminated effective immediately prior to the Effective Time.

(g) At the Effective Time, each Company 2008 Warrant that is issued, unexpired and unexercised immediately prior to the Effective Time shall be assumed by Parent and become and represent a warrant to purchase the number of shares of Parent Common Stock (a “Parent Warrant”) (decreased to the nearest full share) determined by multiplying (i) the number of shares of Company Common Stock subject to such Company ▇▇▇▇ ▇▇▇▇▇▇▇ immediately prior to the Effective Time by (ii) the Option Exchange Ratio, at an exercise price per share of Parent Common Stock (rounded up to the nearest cent) equal to the exercise price per share of Company Common Stock under such Company ▇▇▇▇ ▇▇▇▇▇▇▇ immediately prior to the Effective Time divided by the Option Exchange Ratio. After the Effective Time, except as provided above in this Section 6.04(g), each Parent Warrant shall be exercisable upon the same terms and conditions as were applicable under the related Company ▇▇▇▇ ▇▇▇▇▇▇▇ immediately prior to the Effective Time. The Company shall take all necessary action to implement and make effective the provisions of this Section 6.04(g).

(h) At the Effective Time, each Company 2010 Warrant that is issued, unexpired and unexercised immediately prior to the Effective Time shall be cancelled and converted into and shall thereafter represent the right to receive, upon payment of the aggregate exercise price of such Company 2010 Warrant, the combination of (x) the product of the Per Share Cash Amount (without interest, and subject to deduction for any required withholding Taxes), multiplied by the number of shares of Company Common Stock subject to such Company ▇▇▇▇ ▇▇▇▇▇▇▇ as of immediately prior to the Effective Time, and (y) the number of shares of Parent Common Stock (decreased to the nearest full share) equal to the product of the Exchange Ratio, multiplied by the number of shares of Company Common Stock subject to such Company ▇▇▇▇ ▇▇▇▇▇▇▇ as of immediately prior to the Effective Time. The Company shall take all necessary action to implement and make effective the provisions of this Section 6.04(h).

SECTION 6.05. Employee Benefits.

(a) From the Closing Date until the first anniversary thereof, Parent shall cause the Surviving Company to provide each employee of the Company and the Company Subsidiaries (each, a “Company Employee”) with employee benefits and compensation that are substantially comparable in the aggregate to the employee benefits and compensation that are provided to similarly situated employees of Parent and the Parent Subsidiaries.

(b) Parent agrees that it will cause the Surviving Company from and after the Effective Time to honor all Company Benefit Plans and Company Benefit Agreements; provided, however, that nothing in this Agreement shall be interpreted as limiting the power of Parent or the Surviving Company to amend or terminate any Company Benefit Plan, any Company Benefit Agreement or any other individual employee benefit plan, program, Contract or policy or as requiring Parent or the Surviving Company to offer to continue the employment of any employee or independent contractor or, other than as required by its terms, any written employment contract.

(c) With respect to each employee benefit plan in which a Company Employee becomes a participant, Parent shall cause the Surviving Company to (i) fully credit each participating Company Employee for eligibility and vesting purposes under such employee benefit plan for such Company Employee’s service with the Company or one of the Company Subsidiaries prior to the Closing Date; provided, that no such service need be given where such credit would result in a duplication of benefits, (ii) fully credit each participating Company Employee for any coinsurance, copayments and deductibles paid and for amounts paid toward any out-of-pocket maximums prior to the date the Company Employee becomes a participant in such employee benefit plan with respect to the calendar year in which such participation commences, and (iii) waive all limitations as to pre-existing conditions and exclusions with respect to participation and coverage requirements applicable to such Company Employees.

(d) Parent shall pay or cause the Surviving Company to pay each Company Employee all annual bonuses earned by such Company Employee with respect to the 2012 calendar year at the same time and in a manner no less favorable to the Company Employees than the employee bonuses of similarly situated employees of Parent and the Parent Subsidiaries.

(e) Upon the written request of Parent, effective as of the day immediately preceding the Closing Date, the Company and Company Subsidiaries, as applicable, shall each use its commercially reasonable efforts to terminate any and all Company Benefit Plans intended to include a Code Section 401(k) arrangement (collectively, the “Company 401(k) Plans”). The form and substance of such resolutions shall be subject to the review and reasonable approval of Parent.

(f) Nothing in this Agreement shall be interpreted as an amendment or other modification of any Company Benefit Plan, Company Benefit Agreement, Parent Benefit Plan or Parent Benefit Agreement or any other employee benefit plan, program or arrangement or the establishment of any employee benefit plan, program or arrangement. Nothing herein shall be

deemed to be a guarantee of employment for any employee of the Surviving Company or any of its subsidiaries, or to restrict the right of the Surviving Company, Parent or any of their respective subsidiaries to terminate or cause to be terminated the employment of any employee at any time for any or no reason with or without notice.

(g) Parent and the Company acknowledge and agree that all provisions contained in this Section 6.05 are included for the sole benefit of Parent, US Corp., Merger Sub, Merger LLC, the Company, the Surviving Company and their respective subsidiaries, and that nothing in this Section 6.05, whether express or implied, shall create any third party beneficiary or other rights (A) in any other Person, including any employees, former employees, any participant in any employee benefit plan, program or arrangement (or any dependent or beneficiary thereof) of Parent, the Company or the Surviving Company or any of their respective subsidiaries or (B) to continued employment with Parent, the Company, the Surviving Company, or any of their respective subsidiaries or continued participation in any employee benefit plan, program or arrangement.

SECTION 6.06. Indemnification; Directors and Officers Insurance.

(a) Parent, US Corp., Merger Sub and Merger LLC each agree that all rights to exculpation or indemnification arising from, relating to, or otherwise in respect of, acts or omissions occurring prior to the Effective Time now existing in favor of the current or former directors or officers of the Company and the Company Subsidiaries as provided in their respective certificates of incorporation, by-laws or other organizational documents shall survive the Merger and the Subsequent Merger and shall continue in full force and effect in accordance with their terms. For a period of no less than six (6) years from the Effective Time, Parent shall cause the Surviving Company to, and the Surviving Company shall, maintain in effect the exculpation, indemnification and advancement of expenses provisions of the Company’s and any Company Subsidiary’s certificate of incorporation and by-laws or similar organization documents in effect as of the date of this Agreement or in any indemnification agreements of the Company or the Company Subsidiaries with any of their respective directors, officers or employees in effect as of the date of this Agreement, and shall not amend, repeal or otherwise modify any such provisions in any manner that would adversely affect the rights thereunder of any individuals who immediately before the Effective Time were current or former directors, officers or employees of the Company or any Company Subsidiaries; provided, however, that all rights to indemnification in respect of any Proceeding pending or asserted or any claim made within such period shall continue until the final disposition of such Proceeding.

(b) Each of Parent and the Surviving Company shall, to the fullest extent permitted under applicable Law, indemnify and hold harmless (and advance funds in respect of each of the foregoing and costs of defense to) each current and former director or officer of the Company or any Company Subsidiaries (each, together with such individual’s heirs, executors or administrators, an “Indemnified Party”), in each case against any losses, claims, damages, liabilities, fees and expenses (including attorneys’ fees and disbursements), judgments, fines and amounts paid in settlement in connection with any actual or threatened Proceeding, whether civil, criminal, administrative or investigative, arising out of, relating to or in connection with the fact that such Indemnified Party is or was an officer, director or fiduciary of the Company or any Company Subsidiaries at or prior to the Effective Time; provided, however, that the Indemnified

Party to whom expenses are advanced provides an undertaking, if and only to the extent required by applicable Law, to repay such advances if it is ultimately determined that such Indemnified Party is not entitled to indemnification for such expenses. No Indemnified Party shall settle, compromise or consent to the entry of any judgment in any threatened or actual Proceeding for which indemnification could be sought by an Indemnified Party hereunder unless Parent consents in writing to such settlement, compromise or consent (which consent shall not be unreasonably withheld, conditioned or delayed).

(c) Parent shall use its reasonable best efforts to obtain, at or prior to the Effective Time, prepaid (or “tail”) directors’ and officers’ insurance and indemnification policies that provide coverage for events occurring prior to the Effective Time for an aggregate period of not less than six (6) years from the Effective Time that are substantially similar (with respect to limits and deductibles) to the Company’s existing policy. If such “tail” insurance policy is unavailable on commercially reasonable terms, then Parent shall provide, or shall cause the Surviving Company to provide, the Company’s current directors and officers an insurance and indemnification policy that provides coverage for events occurring prior to the Effective Time for an aggregate period of not less than six (6) years from the Effective Time (the “Annual D&O Policy”) that is substantially similar (with respect to limits and deductibles) to the Company’s existing policy or, if substantially similar insurance coverage is unavailable, the best available coverage; provided, however, that Parent and the Surviving Company shall not be required to pay an annual premium for the Annual D&O Policy in excess of 300% of the last annual premium paid prior to the date of this Agreement (the “Company’s Current Premium”). If such premiums for such Annual D&O Policy would at any time exceed 300% of the Company’s Current Premium, then Parent shall use its reasonable best efforts to cause to be maintained policies of insurance which, in Parent’s good faith determination, provide the maximum coverage available at an annual premium equal to 300% of the Company’s Current Premium. The Company represents to Parent that the Company’s Current Premium is $595,404.

(d) If Parent, the Surviving Company or any of their respective successors or assigns (i) consolidates with or merges into any other Person and shall not be the continuing or surviving entity of such consolidation or merger or (ii) transfers or conveys all or substantially all its properties and assets, then, and in each case, Parent and the Surviving Company shall ensure that such surviving entity or the transferees of such properties or assets assume the obligations set forth in this Section 6.06.

SECTION 6.07. Fees and Expenses.

(a) Except as provided below, all fees and expenses incurred in connection with the Merger, the Subsequent Merger and the other Transactions, including the fees and disbursements of counsel, financial advisors and accountants, shall be paid by the party incurring such fees or expenses, whether or not the Merger and the Subsequent Merger is consummated; provided, however, that all HSR Act filing fees and all costs and expenses incurred in connection with the printing, filing and mailing of the Joint Proxy Statement and the Form S-4 (including the applicable SEC filing fees) shall be divided equally between Parent and the Company.

(b) Notwithstanding anything in this Agreement to the contrary, if (i) this Agreement is terminated by the Company or Parent pursuant to Section 8.01(b)(i) or Section

Notwithstanding anything in this Agreement to the contrary, in the event of a Financing Failure, the Company’s right to receive payment of the Parent Financing Failure Fee pursuant to Section 6.07(f) shall be the sole and exclusive remedy of the Company and the Company Subsidiaries and all rights or claims, whether at Law or in equity, in contract, tort or otherwise, of the Company, the Company Subsidiaries or any stockholders, partners, members, Affiliates, directors, officers, employees, representatives or agents of the Company and the Company Subsidiaries, and any Affiliate of any of the foregoing are hereby deemed waived, against Parent, US Corp., Merger Sub and Merger LLC and their respective Affiliates and Representatives (and any of their respective Affiliates and any of such entities’ or their Affiliates’ respective former, current or future general or limited partners, shareholders, managers, members, directors, officers, employees, representatives or agents in connection with this Agreement, the Financing or the Financing Letter) for any and all losses, damages and expenses suffered or incurred by the Company or any other Person in connection with this Agreement or the Transactions or the Financing and upon payment of such amount, none of Parent, US Corp., Merger Sub, Merger LLC or any of their respective Affiliates or Representatives shall have any further liability or obligation relating to or arising out of this Agreement or the Transactions or the Financings, in each case whether at Law, in equity, in contract, in tort or otherwise, by the enforcement of any assessment, by any legal or equitable Proceeding, by virtue of any statute, regulation or applicable Laws or otherwise and whether by or through a claim by or on behalf of a party hereto or any Third Party (including a claim to enforce the Financing Letter) or otherwise, other than in the case of Sections 6.07(a), 6.07(h) and any obligations of Parent pursuant to the last sentence of Section 6.02.

(h) Each of the Company and Parent acknowledges that the agreements contained in this Section 6.07 are an integral part of the Transactions, and that, without these agreements neither Parent nor the Company would have entered into this Agreement; accordingly, if the Company fails to promptly pay the amounts due pursuant to Sections 6.07(b) or 6.07(c) or Parent fails to promptly pay the amounts due pursuant to Sections 6.07(d), 6.07(e) or 6.07(f), and, in order to obtain such payment Parent or the Company, as the case may be, commences a suit which results in a Judgment against the Company or Parent, as applicable, for any of the amounts set forth in Sections 6.07(b), 6.07(c), 6.07(d), 6.07(e) or 6.07(f) then the Company shall pay to Parent or Parent shall pay to the Company, as the case may be, its costs and expenses (including attorneys’ fees) in connection with such suit, together with interest on the amounts due pursuant to Sections 6.07(b), 6.07(c), 6.07(d), 6.07(e) or 6.07(f) at the prime rate of JPMorgan Chase Bank, N.A. in effect on the date of payment plus 2% per annum from the date such amounts were required to be paid until the date actually received by such party.

(a) The Company agrees to make such reasonable representations as requested by counsel for the purpose of rendering the opinion described in Section 1.08(c).

(b) From the date of this Agreement to the Effective Time, neither the Company nor any Company Subsidiary shall take any action or fail to take any action which action or failure, to the Knowledge of the Company, would disqualify the Merger and the Subsequent Merger, taken together, as a “reorganization” within the meaning of Section 368(a) of the Code, if they would otherwise so qualify.

(c) From the date of this Agreement to the Effective Time, neither Parent nor any Parent Subsidiary shall take any action or fail to take any action which action or failure, to the Knowledge of Parent, would disqualify the Merger and the Subsequent Merger, taken together, as a “reorganization” within the meaning of Section 368(a) of the Code, if they would otherwise so qualify.

(d) Provided that the opinions described in Section 1.08(c) are received on or prior to the Closing Date, each of Parent, US Corp., Merger Sub, Merger LLC and the Company hereby adopt this Agreement as a plan of reorganization within the meaning of Sections 1.368-2(g) and 1.368-3(a) of the U.S. Treasury Regulations.

SECTION 6.12. Financing.

(a) Parent’s, US Corp.’s and Merger Sub’s obligations hereunder are not subject to any conditions regarding Parent’s, US Corp.’s, Merger Sub’s or any other person’s ability to finance, or obtain financing for, the Transactions.

(b) From and after the execution of this Agreement, Parent, US Corp. and Merger Sub shall use their respective reasonable best efforts to arrange the Financing on the terms and conditions described in the Financing Letter and shall not permit any amendment or modification to be made to, any replacement of all or any portion of any facilities (or commitments thereof) described in, or any waiver of any provision or remedy under, the Financing Letter, if such amendment, modification, replacement or waiver (i) reduces the aggregate amount of the Financing (including by changing the amount of fees to be paid or original issue discount except by operation of the “flex” provisions in the related fee letter) unless such reduction is replaced with Replacement Financing or cash on hand or (ii) imposes new or additional conditions or otherwise expands, amends or modifies any of the conditions to the receipt of any portion of the Financing in a manner that would or would reasonably be expected to (A) delay or prevent the Closing or the Closing Date, (B) make the funding of the Financing (or satisfaction of the conditions to obtaining the Financing) less likely to occur or (C) adversely impact the ability of Parent, US Corp. or Merger Sub, as applicable, to enforce their rights against other parties to the Financing Letter or the definitive agreements to be entered into with respect to the Financing, including any right to seek specific performance of the Financing Letter or such definitive agreements. Subject to the limitations set out in the first sentence of this Section 6.12(b), Parent, US Corp. and Merger Sub may (1) amend, supplement, modify, replace or substitute the Financing Letter as in effect at the date hereof, including to (x) add or replace lenders, lead arrangers, bookrunners, syndication agents or similar entities who had not executed the Financing Letter as of the date of this Agreement, (y) increase the amount of Indebtedness and (z) replace all or a portion of the facility committed under the Financing Letter as in effect as of the date hereof with one or more new facilities under such Financing Letter or under any new commitment letter or facility or (2) replace all or a portion of the Financing with substitute or replacement debt financing or equity financing (consistent with the equity financing described in Section 4.02(a) of the Parent Disclosure Letter) (any such new commitment or facility described in clause (z) above or Financing described in clause (2) above, a “Replacement Financing”), provided that any amendments, modifications or replacements of any Replacement Financing shall be subject to the same limitations that apply to the Financing Letter as set forth in the first sentence of this Section 6.12(b). From and after the execution of this Agreement, Parent, US Corp. and Merger Sub shall use their respective reasonable best efforts to obtain a corporate credit rating from each of Standard & Poor’s Ratings Services and ▇▇▇▇▇’▇ Investor’s Services, Inc.

(c) Subject to the terms and conditions of this Agreement, each of Parent, US Corp. and Merger Sub will use its reasonable best efforts to maintain in effect the Financing

Letter pursuant to its terms until the Merger is consummated and to obtain the Financing on the terms and conditions described in the Financing Letter, including using its reasonable best efforts (i) to negotiate and enter into definitive agreements with respect thereto on the terms and conditions contained in the Financing Letter (including any applicable “flex” provisions contained in the related fee letter), (ii) to satisfy all conditions on a timely basis to obtaining the Financing applicable to each of Parent, US Corp. and Merger Sub set forth in such definitive agreements that are within its control, (iii) to comply in all respects with its covenants and obligations under the Financing Letter and (iv) subject to Section 6.07, to enforce through exercise of all available remedies its rights under the Financing Letter in the event of a breach or other failure to fund by the Lenders. Parent shall give the Company prompt notice upon becoming aware of any of the following: (A) any material breach or default of the Financing Letter by a party to the Financing Letter or definitive document with respect to the Financing of which they become aware; (B) the receipt of any written notice or other written communication from any Financing Source with respect to any breach, default, termination or repudiation by any party to the Financing Letter or any definitive document related to the Financing of any provisions of the Financing Letter or any definitive document related to the Financing and (C) if for any reason Parent, US Corp. or Merger Sub believes in good faith that they will not be able to obtain all or any portion of the Financing required to consummate the Transactions. Parent shall keep the Company informed on a reasonable basis and in reasonable detail of the status of its efforts to arrange the Financing and provide to the Company, upon its written request, copies of the definitive material documents related to the Financing (other than fee letters and any other documentation subject to confidentiality restrictions). Notwithstanding the foregoing, nothing in this Section 6.12(c) shall require Parent to disclose any information that is subject to attorney-client or similar privilege if Parent shall have used its reasonable best efforts to disclose such information in a way that would not waive such privilege. Subject to the terms and conditions of this Agreement, in the event that all conditions in the Financing Letter have been satisfied or, upon funding, will be satisfied, Parent, US Corp. and Merger Sub shall use their reasonable best efforts to cause the Lenders to fund on the Closing Date the Financing required to consummate the Merger, the Subsequent Merger and the other Transactions. In the event that Parent, US Corp. or Merger Sub becomes aware of any event or circumstance that makes procurement of any portion of the Financing unlikely to occur in the manner or from the sources contemplated in the Financing Letter, Parent, US Corp. or Merger Sub shall, in addition to promptly notifying the Company in writing of such event or circumstance, use their respective reasonable best efforts to, as promptly as practicable, arrange any such portion (other than amounts that are replaced by Parent’s cash on hand and marketable securities) from alternative sources (such portion from alternate sources, the “Alternate Financing”) in an amount sufficient to consummate the transactions contemplated hereby; provided, however, that Parent, US Corp. and Merger Sub shall not be required to agree to terms and conditions (including any “flex” provisions) that are, in the aggregate, materially less favorable to Parent, US Corp. and Merger Sub than those contained in the Financing Letter (and the “flex” provisions contained in the related fee letter). For the avoidance of doubt, the syndication of any part of the Financing in accordance with the terms of the Financing Letter shall not be deemed to violate Parent’s obligations under this Agreement.

(d) Prior to the Closing, the Company shall provide, and shall cause the Company Subsidiaries to provide, and shall use its reasonable best efforts to cause its and their Representatives, officers and employees to provide, on a timely basis, all reasonable cooperation

requested by Parent in connection with the arrangement of the Financing to the extent that such cooperation does not unreasonably interfere with the ongoing operations of the Company and the Company Subsidiaries, including (i) using reasonable best efforts to facilitate the provision of guarantees and pledge of collateral (effective as of the actual occurrence of Closing), (ii) providing customary financial and other pertinent information regarding the Company and the Company Subsidiaries and cooperating in the preparation of pro forma financial information for the Transactions (including information to be used in the preparation of an information package, offering memorandum, prospectus, prospectus supplement or similar document regarding the business, assets, operations, financial projections and prospects of Parent and the Company customary for such financing or reasonably necessary for the completion of the Financing), including the financial information required to be delivered pursuant to the Financing Letter and such other information as may be reasonably requested in writing by Parent to assist in preparation of customary offering or information documents to be used for the completion of the Financing, (iii) reasonably cooperating with the marketing efforts for the Financing (it being acknowledged that the Company hereby consents to the reasonable use of the Company’s and the Company Subsidiaries’ logos provided that such logos are used in a manner that is not reasonably likely to harm or disparage the Company or their marks and on such other customary terms and conditions as the Company shall reasonably impose) and using commercially reasonable efforts to provide an introduction and access to the Company’s existing lenders in connection with any syndication efforts, (iv) providing copies of any recent appraisals, environmental reports, evidence of title (including copies of deeds, lease documentation, title insurance policies and/or commitments for title insurance, title opinions, surveys, and similar information), and similar information with respect to the properties and assets of the Company and the Company Subsidiaries that are in the Company’s possession and that are reasonably requested by Parent, (v) providing other reasonably requested customary certificates, opinions or documents, including a customary certificate of the principal financial officer of the Surviving Company (in his capacity as such) with respect to solvency matters, (vi) requesting such customary legal opinions and customary accountant comfort letters (including consents of accountants for use of their reports in any materials relating to the Financing) as may be reasonably requested by Parent, (vii) participating in a reasonable number of meetings (including customary one-on-one meetings with the parties acting as lead arrangers or underwriters, as applicable, for the Financing and their counsel and senior management and Representatives, with appropriate seniority and expertise, of the Company), presentations, road shows, drafting sessions, due diligence sessions (including accounting due diligence sessions) and sessions with the rating agencies as are customary and reasonably requested by Parent, (viii) providing reasonable and customary assistance to Parent and its financing sources or underwriters, as applicable, in (A) the preparation of all credit agreements (including review of schedules for completeness), currency or interest hedging agreements or other agreements, offering documents, an offering memorandum, prospectus or prospectus supplement and other marketing and rating agency materials for the Financing or (B) the amendment or termination of any of the Company’s or the Company Subsidiaries’ existing credit agreements, currency or interest hedging agreements, or other agreements and the release of all collateral and termination of all security interests thereunder (including by negotiating a payoff letter in customary form satisfactory to Parent with respect to any and all obligations of the Company and the Company Subsidiaries under their existing credit facilities, a copy of which shall be delivered to Parent no less than five Business Days prior to the Closing Date), in each case, on terms satisfactory to
