MERGER

5.1 Merger.

(a) Purchaser agrees to, and Parent agrees to cause Purchaser to, effect the Merger within one business day following the Closing in accordance with Section 253 of the DGCL by filing all necessary documentation, including by filing a Certificate of Ownership and Merger with the Secretary of State of the State of Delaware (the “Secretary of State”) in accordance with Section 253 of the DGCL. The Merger shall become effective at the time that the Certificate of Ownership and Merger is duly filed with the Secretary of State. The time when the Merger becomes effective is hereinafter referred to as the “Effective Time”.

(b) At the Effective Time, (i) Purchaser shall be merged with and into the Company, whereupon the separate existence of Purchaser shall cease and (ii) the Company shall be the surviving corporation in the Merger (the “Surviving Corporation”) and shall continue to be governed by the laws of the State of Delaware. The Merger shall have the effects set forth in this Agreement and the applicable provisions of the DGCL. Without limiting the generality of the foregoing, and subject thereto, at the Effective Time, all property, rights, powers, privileges and franchises of the Company and Purchaser shall vest in the Surviving Corporation, and all debts, liabilities and duties of the Company and Purchaser shall become the debts, liabilities and duties of the Surviving Corporation.

(c) At the Effective Time, by virtue of the Merger and without any action on the part of any holder of any share of Company Common Stock:

(i) each share of common stock of Purchaser issued and outstanding immediately prior to the Effective Time shall be converted into and become one validly issued, fully paid and non-assessable share of common stock of the Surviving Corporation, and from and after the Effective Time, all certificates representing the common stock of Purchaser shall be deemed for all purposes to represent the number of shares of common stock of the Surviving Corporation into which they were converted in accordance with this sentence;

(ii) all shares of Company Common Stock that are held by the Company as treasury shares and any shares of Company Common Stock owned by Purchaser, Parent, and any Subsidiary of Parent or Purchaser immediately prior to the Effective Time shall be canceled and retired and shall cease to exist, and no stock of the Surviving Corporation or other consideration shall be delivered in exchange therefor;

(iii) each issued and outstanding share of Company Common Stock (other than shares to be canceled in accordance with Section 5.1(c)(ii) above and other than shares for which the holder has demanded and perfected such holder’s right to an appraisal in accordance with the DGCL and has not effectively withdrawn or lost such right to appraisal (“Dissenting Shares”)) shall be converted into the right to receive (A) an amount in cash equal to the quotient obtained by dividing (1) $11,300,000 by (2) 201,447,114 (the “Cash Portion” and with the aggregate Cash Portion payable to each holder of Company Common Stock to be rounded down to the nearest cent) and (B) one CVR (together with the Cash Portion, the “Per Share Merger Price”), without interest; and

(iv) each share of Company Common Stock converted in accordance with Section 5.1(c)(iii) above shall as of the Effective Time no longer be outstanding and shall automatically be canceled and retired and shall cease to exist, and each Certificate and each Book-Entry Share which immediately prior to the Effective Time represented such shares shall thereafter represent only the right to receive the Per Share Merger Price to which they are entitled therefor. Certificates and Book-Entry Shares previously representing shares of Company Common Stock (other than any shares to be canceled in accordance with Section 5.1(c)(ii) above) shall be exchanged for the Per Share Merger Price payable for the shares previously represented thereby, without interest, upon the surrender of such Certificates or Book-Entry Shares in accordance with the provisions of Section 5.2.

(d) At the Effective Time, by virtue of the Merger and without any action on the part of the holder thereof, each outstanding Dissenting Share shall not be converted into or represent a right to receive the Per Share Merger Price pursuant to Section 5.1(c)(iii) above, but the holder thereof shall be entitled only to such rights as are granted by the applicable provisions of the DGCL; provided, however, that any Dissenting Share held by an individual or entity at the Effective Time who shall, after the Effective Time, withdraw the demand for appraisal or lose the right of appraisal, in either case pursuant to the DGCL, shall be deemed to be converted into, as of the Effective Time, the right to receive the Per Share Merger Price pursuant to Section 5.1(c)(iii) above.

(e) At the Effective Time, (i) the Company Certificate of Incorporation, as in effect immediately prior to the Effective Time, shall be amended as set forth in the form attached to the Certificate of Ownership and Merger and, as so amended, shall be the certificate of incorporation of the Surviving Corporation, until thereafter duly amended as provided therein and by applicable Law, and (ii) the bylaws of Purchaser, as in effect immediately prior to the Effective Time, shall be the bylaws of the Surviving Corporation, until thereafter duly amended as provided therein and by applicable law.

(f) The officers of Purchaser immediately prior to the Effective Time shall, from and after the Effective Time, be officers of the Surviving Corporation until their respective successors have been duly elected or appointed and qualified or until their earlier death, resignation or removal in accordance with the DGCL and the certificate of incorporation and the bylaws of the Surviving Corporation.

(g) The directors set forth on Schedule 5.1(g) shall, from and after the Effective Time, be directors of the Surviving Corporation until their respective successors have been duly elected or appointed and qualified or until their earlier death, resignation or removal in accordance with the DGCL and the certificate of incorporation and the bylaws of the Surviving Corporation.

5.2 Payment Procedures.

(a) CVR Rights Agent and Paying Agent. Prior to the Effective Time, Parent and the Company shall, and Parent shall cause the CVR Rights Agent to, authorize, execute and deliver the CVR Agreement. Prior to the Effective Time, Parent shall select a reputable bank or trust company reasonably satisfactory to the Company to act as paying agent in the Merger (the “Paying Agent”). At or prior to the Effective Time, Parent shall, or shall cause Purchaser to, deposit with the Paying Agent, for the benefit of the holders of shares of Company Common Stock, for exchange in accordance with this Article 5, cash in U.S. dollars in an amount sufficient to pay the aggregate amount of the Cash Portion of the Per Share Merger Price payable to the holders of all outstanding shares of Company Common Stock (such cash being hereinafter referred to as the “Exchange Fund”). The Exchange Fund shall be invested by the Paying Agent as reasonably directed by Parent; provided, however, that: (a) no such investment or any losses thereon shall affect the aggregate Per Share Merger Price payable to the holders of Company Common Stock and following any losses Parent shall, or shall cause Purchaser to, promptly provide additional funds to the Paying Agent for the benefit of the holders of the shares of the Company Common Stock in the amount of any such losses and (b) such investments shall be in obligations of or guaranteed by the United States of America or any agency or instrumentality thereof and backed by the full faith and credit of the United States of America, in commercial paper obligations rated A-1 or P-1 or better by Xxxxx’x Investors Service, Inc. or Standard & Poor’s Corporation, respectively, or in certificates of deposit, bank repurchase agreements or banker’s acceptances of commercial banks with capital exceeding $10,000,000,000 (based on the most recent financial statements of such bank that are then publicly available). Any net profit resulting from, or interest or income produced by, such investments shall be payable to the Surviving Corporation. The Exchange Fund shall not be used for any other purpose. Parent shall not be required to deposit any of the funds related to any CVR with the CVR Rights Agent unless and until such deposit is required pursuant to the terms of the CVR Agreement.

(b) Exchange Procedures. Promptly following the Effective Time (but in no event later than ten (10) days following the Effective Time) Parent shall cause the Paying Agent to mail to each registered holder of a certificate or certificates which immediately prior to the Effective Time represented outstanding shares of Company Common Stock (the “Certificates”) or of non-certificated shares of Company Common Stock represented by book-entry (“Book-Entry Shares”) (i) a letter of transmittal in customary form (which shall specify that delivery

shall be effected, and risk of loss and title to the Certificates shall pass, only upon proper delivery of the Certificates to the Paying Agent and which shall include customary provisions with respect to delivery of an “agent’s message” with respect to Book-Entry Shares) and (ii) instructions for use in effecting the surrender of Certificates (or affidavits of loss in lieu thereof) or Book-Entry Shares in exchange for the Per Share Merger Price to which such holder is entitled. Upon surrender of Certificates (or affidavits of loss in lieu thereof), or in the case of Book-Entry Shares, upon adherence to the applicable procedures set forth in the letter of transmittal, for cancellation to the Paying Agent together with such letter of transmittal, properly completed and duly executed in accordance with the instructions thereto, and such other customary documents as may be reasonably required by the Paying Agent or pursuant to such instructions, the holders of such Certificates or Book-Entry Shares shall (A) be entitled to receive, and the Paying Agent shall (and Parent shall cause the Paying Agent to), in exchange therefor, transfer from the Exchange Fund to each such holder the Cash Portion of the Per Share Merger Price such holder has the right to receive pursuant to Section 5.1(c)(iii) hereof, and (B) be identified by Parent, or caused to be identified by Parent, in the register maintained by the CVR Rights Agent for the purpose of identifying the holders of CVRs pursuant to the terms of the CVR Agreement, as the holder of that number of CVRs such holder has the right to receive pursuant hereto, in accordance with the CVR Agreement, and the Company Common Stock formerly represented by such Certificates or Book-Entry Shares, and the Certificates or Book-Entry Shares so surrendered shall forthwith be canceled.

No interest will be paid or accrued on the Per Share Merger Price payable to holders of Certificates or Book-Entry Shares. In the event of a transfer of ownership of shares of Company Common Stock which is not registered in the transfer records of the Company, the applicable Per Share Merger Price may be issued to a transferee if the Certificate representing such shares of Company Common Stock is presented to the Paying Agent (or in the case of Book-Entry Shares, upon adherence to the applicable procedures set forth in the letter of transmittal), accompanied by all documents required to evidence and effect such transfer and by evidence that any applicable stock transfer Taxes have been paid. Until surrendered as contemplated by this Section 5.2, each Certificate and each Book-Entry Share shall be deemed at any time after the Effective Time to represent only the right to receive for each share of Company Common Stock upon such surrender the Per Share Merger Price to which such share is entitled or the right to demand appraisal of Dissenting Shares pursuant to the DGCL.

(c) Further Rights in Company Common Stock. The aggregate Per Share Merger Price paid in accordance with the terms hereof shall be deemed to have been issued in full satisfaction of all rights pertaining to the applicable shares of Company Common Stock and any and all rights to receive dividends or distributions with respect to the Company Common Stock declared from and after the Closing Date shall terminate.

(d) Termination of Exchange Fund. Any portion of the Exchange Fund (including any interest received with respect thereto) which remains undistributed to the holders of Company Common Stock on the first anniversary of the Effective Time shall be delivered to the Surviving Corporation upon demand, and any holders of Company Common Stock who have not theretofore complied with this Article 5 shall thereafter look only to Parent or the Surviving Corporation (subject to abandoned property, escheat or other similar Laws) for payment of the Per Share Merger Price to which they are entitled, without any interest thereon. Purchaser shall pay all charges and expenses, including those of the Paying Agent and the CVR Rights Agent, in connection with the exchange of shares of Company Common Stock for the Per Share Merger Price.

(e) No Liability. None of Parent, the Company or the Surviving Corporation shall be liable to any holder of shares of Company Common Stock entitled to payment of the Per Share Merger Price under this Article 5 for any cash from the Exchange Fund properly delivered to a public official pursuant to any abandoned property, escheat or other similar Law.

(f) No Further Dividends. No dividends or other distributions with respect to capital stock of the Surviving Corporation with a record date on or after the Effective Time shall be paid to the holder of any unsurrendered Certificates.

(g) Lost Certificates. If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed in the form required by the Paying Agent and, if required by the Surviving Corporation, the posting by such Person of a bond, in such reasonable and customary amount as the Surviving Corporation may direct, as indemnity against any claim that may be made with respect to such lost, stolen or destroyed Certificate, the Paying Agent will issue in exchange for each share represented by such lost, stolen or destroyed Certificate the applicable Per Share Merger Price for each such share without any interest thereon.

(h) Stock Transfer Books. At the Effective Time, the stock transfer books of the Company shall be closed and thereafter there shall be no further registration of transfers of shares of Company Common Stock outstanding on the records of the Company prior to the Effective Time. From and after the Effective Time, the holders of Certificates and Book-Entry Shares shall cease to have any rights with respect to the shares of Company Common Stock represented thereby except as otherwise provided herein or by Law. From and after the Effective Time, any Certificates presented to the Paying Agent or the Surviving Corporation for transfer or any other reason shall be cancelled and each share represented thereby shall be exchanged for the Per Share Merger Price as provided in, and in accordance with, this Article 5.

5.3 Dissenters’ Rights. No later than ten days following the Effective Time, Parent shall cause the Surviving Corporation to deliver notice thereof to holders of Company Common Stock in compliance with Section 262 of the DGCL. Notwithstanding anything in this Agreement to the contrary, if any holder of Dissenting Shares shall demand to be paid the “fair value” of its Dissenting Shares, as provided in Section 262 of the DGCL, such Dissenting Shares shall not be converted into or exchangeable for the right to receive the Per Share Merger Price (except as provided in this Section 5.3) and shall entitle such holder of Dissenting Shares only to be paid the “fair value” of such Dissenting Shares, in accordance with Section 262 of the DGCL, unless and until such holder (a) withdraws (in accordance with Section 262(k) of the DGCL) or (b) effectively loses the right to dissent and receive the “fair value” of such Dissenting Shares under Section 262 of the DGCL. If any holder of Dissenting Shares shall have effectively withdrawn (in accordance with Section 262(k) of the DGCL) or otherwise lost its right to dissent and receive the “fair value” of its Dissenting Shares, then as of the later of the Effective Time or the occurrence of such event, the Dissenting Shares held by such holder shall be cancelled and converted into and represent solely the right to receive the Per Share Merger Price pursuant to

Section 5.1(c)(iii). If any appraisal is made of Dissenting Shares, then the Purchase Price for the Shares shall be treated as if it were not paid to or received by the Company and the Shares issued pursuant to Section 2.1 shall be treated as if they were not issued or outstanding in connection with the determination of the “fair value” of the Dissenting Shares in accordance with the applicable provisions of the DGCL.

6.1 Company Options.

(a) Treatment of Company Options Granted Under the Company’s 2004 Stock Incentive Plan. At the Effective Time, each outstanding Company Option that was granted under the Company’s 2004 Stock Incentive Plan with an exercise per share that is less than the fair market value per share of the Company’s common stock, as determined in good faith by the Company’s Board (such per share price, the “Option FMV” and such Company Option, an “In-the-Money Option”) shall be cancelled and the holders thereof will, in consideration of the cancellation of their Company Options, (i) be entitled to receive from the Surviving Corporation, and the Surviving Corporation shall cause to be delivered to such holders, a cash payment (the “Option Cash Payment”) in an amount equal to the product of (x) the number of shares of Company Common Stock provided for in such In-the-Money Option and (y) the excess of (A) the Option FMV over (B) the exercise price per share provided for in such In-the-Money Option, which Option Cash Payment shall be treated as compensation and shall be net of any applicable withholding Tax. Immediately prior to the Effective Time, each Company Option that was granted under the Company’s 2004 Stock Incentive Plan that is not an In-the-Money Option shall be canceled without any payment being made in respect thereof. The Surviving Corporation shall cause its payroll processor to pay the Option Cash Payments payable to holders who are current or former employees of the Company (“Employee Optionholders”) within two (2) Business Days following the Effective Time.

shall be net of any applicable withholding Tax. Additionally, except for the directors, officers and other employees of the Company set forth on Schedule 6.1(c), as of the date hereof, the Company shall have obtained a termination agreement in a form reasonably satisfactory to Purchaser with respect to each outstanding Non-Plan Option held by the Company’s directors, officers and other employees.

(d) The Company shall cause the vesting and exercisability of all Company Options to be accelerated as of the date hereof. Prior to the date hereof, the Company shall deliver a written notice, approved by Purchaser, to each holder of Company Options that were granted under the Company’s 2010 Equity Incentive Plan informing such holder that (i) contingent on the Effective Time, the vesting and exercisability of all Company Options held by such holder shall be accelerated in full as of the date hereof and (ii) the treatment of such Company Options under this Agreement.

From and after the Effective Time, Parent shall comply, and shall cause the Surviving Corporation to comply, (A) with Section 2(d) and other applicable provisions of each of the Series A Warrants and Series B Warrants and (B) with Section 3(b) and other applicable provisions of the Xxxx Warrants.

Plan) to each Eligible Employee (as defined in the Company Change of Control Plan) through one or more special supplemental payrolls the amount that such Eligible Employee is entitled to receive under the Company Change of Control Plan as a result of the Merger (each, a “Change of Control Payment”), subject to withholding of applicable income and employment Taxes.

6.5 Withholding. The Surviving Corporation and, if applicable, the Paying Agent shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any holder of Company Common Stock, Company Options or Company ESPP Right or to any Company employee entitled to receive a Change of Control Payment such amounts as the Surviving Corporation or the Paying Agent are required to deduct and withhold under the Code, or any applicable provision of state, local or foreign Tax Law, with respect to the making of such payment. To the extent that amounts are so withheld by the Surviving Corporation or, if applicable, the Paying Agent and paid over to the applicable Governmental Entity, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of Company Common Stock, Company Options or Company ESPP Right or to the Company employee entitled to receive a Change of Control Payment in respect of whom such deduction and withholding was made by the Surviving Corporation or the Paying Agent, as the case may be. Notwithstanding the foregoing, except as required by applicable Tax Law, no withholding under Sections 1445 and 897 of the Code shall be made on any amounts payable pursuant to this Agreement provided that the Company delivers to Purchaser at, or prior to, the Closing, a certification (dated not more than 30 days prior to the Closing) and notice to the IRS in the form prescribed by Treasury Regulation Section 1.897-2(h).

(a) During the one (1)-year period commencing at the Effective Time, Parent shall provide or shall cause the Surviving Corporation to provide to Continuing Employees compensation and benefits that are the same as similarly situated employees of Parent or its Subsidiaries prior to the Effective Time, but in no event in the aggregate less favorable than the compensation and benefits being provided to Continuing Employees immediately prior to the Effective Time under the Company Plans. During the one (1)-year period commencing at the Effective Time, the Surviving Corporation shall, and Parent shall cause the Surviving Corporation to, provide to Continuing Employees who experience a termination of employment severance benefits that are no less than the severance benefits that would have been provided to such employees under a Company Plan as of the Effective Time, and severance benefits to Continuing Employees shall be determined without taking into account any reduction after the Effective Time in the compensation paid to Continuing Employees and used to determine severance benefits.

(b) Each Continuing Employee shall be given credit for all service with the Company and its respective predecessors under any employee benefit plan of any Affiliate of Purchaser in which such Continuing Employee is eligible to participate, including any such plans providing vacation, sick pay, severance and retirement benefits maintained by any Affiliate of Purchaser in which such Continuing Employees participate for purposes of eligibility, vesting and entitlement to benefits, including for severance benefits and vacation entitlement (but not for accrual of pension benefits), to the extent past service was recognized for such Continuing Employees under the comparable Company Plans immediately prior to the Effective Time. Notwithstanding the foregoing, nothing in this Section 6.7(b) shall be construed to require crediting of service that would result in (i) duplication of benefits, (ii) service credit for benefit accruals under a defined benefit pension plan or (iii) service credit under a newly established plan for which prior service is not taken into account.

(c) In the event of any change in the welfare benefits provided to Continuing Employees following the Effective Time, the Surviving Corporation shall cause (i) the waiver of all limitations as to pre-existing conditions, exclusions and waiting periods with respect to participation and coverage requirements applicable to the Continuing Employees under any such welfare benefit plans to the extent that such conditions, exclusions or waiting periods would not apply in the absence of such change, and (ii) for the plan year in which the Effective Time occurs, the crediting of each Continuing Employee with any co-payments and deductibles paid prior to any such change in satisfying any applicable deductible or out-of-pocket requirements after such change.

(d) Notwithstanding anything in this Section 6.7 to the contrary but consistent with this Section 6.7, nothing contained herein, whether express or implied, shall be treated as an amendment or other modification of any employee benefit plan of the Surviving Corporation or any of its Affiliates, or shall limit the right of the Surviving Corporation or any of its Affiliates to amend, terminate or otherwise modify any employee benefit plan of the Surviving Corporation or any of its Affiliates following the Effective Time. Except as otherwise required under applicable Laws, Continuing Employees shall be considered to be employed by the Surviving Corporation or its Affiliates “at will” and nothing shall be construed to limit the ability of the Surviving Corporation or its Affiliates to terminate the employment of any such Continuing Employee at any time.

(e) The parties hereto acknowledge and agree that all provisions contained in this Section 6.7 are included for the sole benefit of the parties hereto, and that nothing in this Agreement, whether express or implied, shall create any third-party beneficiary or other rights (i) in any other Person, including any employees or former employees of the Company or any Affiliate of the Company, any Continuing Employee, or any dependent or beneficiary thereof or (ii) to continued employment with the Surviving Corporation or any of its Affiliates.

6.8 Indemnification of Directors and Officers.

(a) Parent and Purchaser agree that all rights of indemnification, exculpation and limitation of liabilities existing in favor of the current or former directors, officers and employees of the Company (the “Indemnified Parties”) as provided in the Company Certificate of Incorporation and the Company Bylaws or under any indemnification, employment or other

similar agreements between any Indemnified Party and the Company, in each case as in effect at the Effective Time with respect to matters occurring prior to the Effective Time, shall survive the Merger and continue in full force and effect in accordance with their respective terms. From and after the Effective Time, Parent and the Surviving Corporation shall be jointly and severally liable to pay and perform in a timely manner such indemnification obligations. For a period of six (6) years after the Effective Time, Parent shall cause the certificate of incorporation and bylaws of the Surviving Corporation shall contain provisions no less favorable with respect to indemnification, exculpation and limitation of liabilities of the Indemnified Parties and advancement of expenses than are set forth as of the date of this Agreement in the Company Certificate of Incorporation and the Company Bylaws.

(b) For a period of six (6) years from and after the Effective Time, Parent shall, and shall cause the Surviving Corporation to, to the fullest extent permitted under applicable Laws, indemnify and hold harmless (and advance funds in respect of each of the foregoing), each present and former director or officer of the Company and each such Person who served at the request of the Company as a director, officer, trustee, partner, fiduciary, employee or agent of another corporation, partnership, joint venture, trust, pension or other employee benefit plan or enterprise, against all costs and expenses (including reasonable attorneys’ fees), judgments, fines, losses, claims, damages, liabilities and settlement amounts paid in connection with any claim, action, suit, proceeding or investigation (whether arising before or after the Effective Time), whether civil, administrative or investigative, arising out of or pertaining to any action or omission in their capacities as officers or directors or in serving at the request of the Company, in each case occurring before the Effective Time (including the transactions contemplated by this Agreement).

(c) In the event that Parent or the Surviving Corporation or any of their respective successors or assigns (i) consolidates with or merges into any other Person and is not the continuing or surviving corporation or entity of such consolidation or merger or (ii) transfers or conveys all or substantially all of its properties and assets to any Person, or if Parent or the Surviving Corporation dissolves, then, and in each such case, proper provision shall be made so that the successors and assigns of Parent or the Surviving Corporation assume the obligations set forth in this Section 6.8.

(d) Parent shall cause the Surviving Corporation, as of the Effective Time, to obtain and fully pay (by wire transfer in immediately available funds) the premium (and any other associated costs) for a non-cancellable extension (or “tail”) of the directors’ and officers’ liability insurance coverage of the Company’s existing directors’ and officers’ insurance policies and the Company’s existing fiduciary liability insurance policies (collectively, “D&O Insurance”), in each case for a claims reporting or discovery period of at least six (6) years from and after the Effective Time (such period, the “Tail Period”) with respect to any claim related to any period of time at or prior to the Effective Time from an insurance carrier with a same or better credit rating than the Company’s current insurance carrier with respect to D&O Insurance with terms, conditions, retentions and limits of liability that are no less favorable than the coverage provided under the Company’s existing policies and covering each Person currently covered by the Company’s existing policies. Parent shall and shall cause the Surviving Corporation to maintain such “tail” policies in full force and effect through such six (6) year period. If Parent, the Company or the Surviving Corporation for any reason fails to obtain such

“tail” insurance policies as of the Effective Time, then from the Effective Time through the end of the Tail Period, the Surviving Corporation shall, and Parent shall cause the Surviving Corporation to, maintain in effect the Company’s current D&O Insurance covering each Person covered by the Company’s D&O Insurance as of immediately prior to the Effective Time for acts or omissions occurring prior to the Effective Time with respect to any matter claimed against such Person by reason of him or her serving in the applicable capacity on terms with respect to such coverage and amounts no less favorable than those of such D&O Insurance policies in effect on the date of this Agreement; provided that in no event shall the costs of such D&O Insurance policies exceed in any one (1) year during the Tail Period 250% of the current aggregate annual premiums paid by the Company for such purpose, it being understood that Parent and the Surviving Corporation shall nevertheless be obligated to provide such coverage, with respect to each year during the Tail Period, as may be obtained for such 250% annual amount; provided, further, that the Surviving Corporation may substitute therefor D&O Insurance policies of any nationally recognized reputable insurance company with a same or better credit rating than the Company’s current insurance carrier with respect to D&O Insurance.

(e) The provisions of this Section 6.8 (i) shall survive the consummation of the Merger, (ii) are intended to be for the benefit of, and shall be enforceable by, each of the Indemnified Parties, their respective heirs and representatives and (iii) are in addition to, and not in substitution for, any other rights to indemnification or contribution that any such Person may have by Contract or otherwise. From and after the Effective Time, the provisions of this Section 6.8 may not be amended in any manner adverse to any Indemnified Party without his or her consent.
