WHEREAS, the board of directors of the Company (the “Company Board”), acting upon the unanimous recommendation of the Special Committee, has (i) determined that it is in the best interests of the Company and the stockholders of the Company, and declared it advisable, to enter into this Agreement with the Parent Group and Merger Sub providing for the merger (the “Merger”) of Merger Sub with and into the Company in accordance with the General Corporation Law of the State of Delaware (the “DGCL”), upon the terms and subject to the conditions set forth herein and (ii) approved and declared advisable this Agreement and the Merger in accordance with the DGCL;

WHEREAS, the respective board of directors of each member of the Parent Group and Merger Sub has each approved this Agreement and the Merger and declared its advisability; and

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

ARTICLE I

THE MERGER

Section 1.1. The Merger. Upon the terms and subject to the conditions of this Agreement and in accordance with the DGCL, at the Effective Time Merger Sub shall be merged with and into the Company. As a result of the Merger, the separate corporate existence of Merger Sub shall cease and the Company shall continue as the surviving corporation of the Merger (the “Surviving Corporation”).

Section 1.2. Closing; Effective Time. Subject to the provisions of Article VI, the closing of the Merger (the “Closing”) shall take place at the offices of Dechert LLP, 1095 Avenue of the Americas, New York, New York, at 10:00 a.m. local time, on the Business Day after the satisfaction or waiver (to the extent permitted by applicable law) of the conditions set forth in Article VI (excluding conditions that by their terms cannot be satisfied until the Closing, but subject to the satisfaction or waiver of those conditions). The date on which the Closing actually occurs is hereinafter referred to as the “Closing Date.” At the Closing, the parties hereto shall cause the Merger to be consummated by filing a certificate of merger (the “Certificate of Merger”) with the Secretary of State of the State of Delaware, in such form as required by, and executed in accordance with, the relevant provisions of the DGCL. The Merger shall become effective at such date and time as the Certificate of Merger is filed with the Secretary of State of the State of Delaware or at such later time (or subsequent date and time) as the Parent Group and the Special Committee (on behalf of the Company) shall agree and specify in the Certificate of Merger. The date and time at which the Merger becomes effective is referred to in this Agreement as the “Effective Time.”

Section 1.3. Effects of the Merger. The Merger shall have the effects set forth herein and in the applicable provisions of the DGCL. Without limiting the generality of the foregoing and subject thereto, at the Effective Time all the property, rights, privileges, powers and franchises of the Company and Merger Sub shall vest in the Surviving Corporation and all debts, liabilities and duties of the Company and Merger Sub shall become the debts, liabilities and duties of the Surviving Corporation.

Section 1.4. Certificate of Incorporation; Bylaws.

(a) At the Effective Time, the Certificate of Incorporation of the Surviving Corporation will be amended and restated at the Effective Time so as to read in the form attached hereto as Exhibit A until thereafter amended as provided by applicable legal requirements.

(b) At the Effective Time, the Bylaws of the Merger Sub, as in effect immediately prior to the Effective Time, shall be the Bylaws of the Surviving Corporation until thereafter amended as provided by applicable legal requirements, the Certificate of Incorporation of the Surviving Corporation and such Bylaws.

Section 1.5. Directors and Officers. The directors of Merger Sub immediately prior to the Effective Time shall be the initial directors of the Surviving Corporation and shall hold office until their respective successors are duly elected and qualified, or their earlier death, resignation or removal. The officers of the Company immediately prior to the Effective Time shall be the initial officers of the Surviving Corporation, each to hold office until the earlier of their death, resignation or removal.

ARTICLE II

EFFECTS OF THE MERGER ON THE CAPITAL STOCK OF THE CONSTITUENT CORPORATIONS

Section 2.1. Conversion of Securities. At the Effective Time, by virtue of the Merger and without any action on the part of the Parent Group, Merger Sub, the Company or the holders of any of the following securities:

(a) Each share of common stock, par value $0.01 per share, of the Company (the “Common Stock”) issued and outstanding immediately prior to the Effective Time, other than any shares of Common Stock (“Shares”) described in Section 2.1(b) and any Dissenting Shares, shall be converted into the right to receive (a) one contractual value right (“CVR”), subject to the terms and provisions of Section 2.4, and (b) $1.40 in cash (the “Cash Consideration,” and together with the CVR, “Merger Consideration”) payable to the holder thereof, without interest, in the manner provided in Section 2.3. All Shares that have been converted into the right to receive the Merger Consideration as provided in this Section 2.1 shall be automatically canceled and shall cease to exist. If, between the date of this Agreement and the Effective Time, there is any change in the number of outstanding Shares as a result of a reclassification, recapitalization, stock split, stock dividend, subdivision, combination or exchange of shares with respect to, or rights issued in respect of, Shares, the Merger Consideration shall be equitably adjusted accordingly, without duplication, to provide to the holders of Shares the same economic effect as contemplated by this Agreement prior to such event;

(b) Each share of capital stock of the Company held in the treasury of the Company and each share of capital stock of the Company owned directly or indirectly by Merger Sub, the Parent Group, any entity to whom they transfer their shares, in whole or in part, or any wholly-owned Subsidiary of the Company immediately prior to the Effective Time (“Canceled Shares”) shall be canceled and shall cease to exist without any conversion thereof and no payment or distribution shall be made with respect thereto;

(c) Each share of capital stock of Merger Sub issued and outstanding immediately prior to the Effective Time shall be converted into and become validly issued, fully paid and nonassessable shares of capital stock of the Surviving Corporation and shall constitute the only outstanding shares of capital stock of the Surviving Corporation; and

(d) Such Shares with respect to which appraisal shall have been properly demanded in accordance with Section 262 of the DGCL (“Dissenting Shares”) shall not be converted into the right to receive the Merger Consideration at or after the Effective Time unless and until the holder of such Shares withdraws such holder’s demand for appraisal (in accordance with Section 262(k) of the DGCL) or otherwise becomes ineligible for such appraisal, but rather the holder of Dissenting Shares shall be entitled only to payment of the fair value of such Dissenting Shares in accordance with Section 262 of the DGCL. If a holder of Dissenting Shares shall withdraw (in accordance with Section 262(k) of the DGCL) the demand for such appraisal or otherwise shall become ineligible for such appraisal, then, as of the Effective Time or the occurrence of such event, whichever last occurs, each of such holder’s Dissenting Shares shall cease to be a Dissenting Share and shall be converted into and represent solely the right to receive the Merger Consideration, without any interest thereon. At the Effective Time, the Dissenting Shares shall no longer be outstanding and shall automatically be cancelled and shall cease to exist, and each holder of Dissenting Shares shall cease to have any rights with respect thereto, except such rights provided in the preceding two sentences.

Section 2.2. Stock Options. Immediately prior to the Effective Time, each then-outstanding option to purchase Shares (a “Company Stock Option”) granted under any director or employee stock option or compensation plan or arrangement of the Company or otherwise, whether or not vested or exercisable, shall be cancelled and the holder of such Company Stock Option shall not receive any cash payment in respect thereof. At or prior to the Effective Time, the Board of Directors shall adopt such resolutions and take such actions as are necessary to effectuate the foregoing provisions of this Section 2.2.

Section 2.3. Surrender of Shares.

(a) Prior to the Effective Time, the Parent Group shall enter into an agreement (in a form reasonably acceptable to the Special Committee) with a paying agent reasonably acceptable to the Special Committee to act as agent for the stockholders of the Company in connection with the Merger (the “Paying Agent”) to receive the Merger Consideration to which the stockholders of the Company shall become entitled pursuant to Section 2.1. At or prior to the Effective Time, the Parent Group shall deposit with the Paying Agent sufficient funds to make all payments of the Cash Consideration pursuant to Section 2.1. Such funds may be invested by the Paying Agent in short term obligations of the United States of America with maturities of no more than 30 days or guaranteed by the United States of America and backed by the full faith and credit of the United States of America. Any interest or income produced by such investments will be payable to the Surviving Corporation or the Parent Group, as the Parent Group directs.

(b) Promptly after the Effective Time and in any event not later than the second Business Day following the Effective Time, the Surviving Corporation shall cause to be mailed to each record holder, as of the Effective Time, of an outstanding certificate or outstanding certificates (“Certificates”) that immediately prior to the Effective Time represented outstanding Shares that have converted into the right to receive the Merger Consideration with respect thereto pursuant to Section 2.1(a), a form of letter of transmittal (which shall be in customary form and shall specify that delivery shall be effected, and risk of loss and title to the Certificates held by such person shall pass, only upon proper delivery of Certificates to the Paying Agent) and instructions for use in effecting the surrender of the Certificates. Upon surrender to the Paying Agent of a Certificate, together with such letter of transmittal, duly completed and validly executed in accordance with the instructions thereto, the holder of such Certificate shall be entitled to receive in exchange therefor the Merger Consideration for each Share formerly represented by such Certificate and such Certificate shall then be canceled. Promptly after the Effective Time and in any event not later than the second Business Day following the Effective Time, the Paying Agent shall issue and deliver to each holder of uncertificated Shares represented by book-entry (“Book-Entry Shares”) a check or wire transfer for the amount of Cash Consideration that such holder is entitled to receive pursuant to Section 2.1(a) of this Agreement in respect of such Book-Entry Shares, without such holder being required to deliver a Certificate or an executed letter of transmittal to the Paying Agent, and such Book-Entry Shares shall then be canceled. No interest shall be paid or accrued for the benefit of holders of the Certificates or Book-Entry Shares on the Merger Consideration payable in respect of the Certificates or Book-Entry Shares. In the event of a transfer of ownership of Shares that is not registered in the transfer records of the Company, it shall be a condition of payment that such Certificate so surrendered shall be properly endorsed or shall be otherwise in proper form for transfer or such Book-Entry Share shall be properly transferred and that the person requesting such payment shall have paid any transfer and other Taxes required by reason of the payment of the Merger Consideration to a person other than the registered holder of the Certificate or Book-Entry Share surrendered or shall have established to the satisfaction of the Parent Group that such Tax either has been paid or is not applicable. Until surrendered as contemplated by this Section 2.3(b), each Certificate, other than Certificates representing Dissenting Shares which shall be treated in accordance with Section 2.2(d) and Certificates representing Cancelled Shares which shall be treated in accordance with Section 2.1(b), shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender the applicable Merger Consideration as and when contemplated by this Article II, without interest.

(c) Prior to the Effective Time, the Parent Group and the Company shall cooperate to establish procedures with the Paying Agent and the Depository Trust Company (“DTC”) to ensure that (i) if the Closing occurs at or prior to 11:30 a.m. (New York time) on the Closing Date, the Paying Agent will transmit to DTC or its nominees on the Closing Date an amount in cash in immediately available funds equal to the number of Shares (other than Cancelled Shares) held of record by DTC or such nominee immediately prior to the Effective Time multiplied by the Cash Consideration (such amount, the “DTC Payment”), and (ii) if the Closing occurs after 11:30 a.m. (New York time) on the Closing Date, the Paying Agent will transmit to DTC or its nominees on the first Business Day after the Closing Date an amount in cash in immediately available funds equal to the DTC Payment.

(d) At any time following the date that is six (6) months after the Effective Time, the Parent Group shall be entitled to require the Paying Agent to deliver to it any funds (including any interest received with respect thereto) that have been made available to the Paying Agent and that have not been disbursed to holders of Certificates and Book-Entry Shares and thereafter such holders shall be entitled to look to the Parent Group and the Surviving Corporation (subject to abandoned property, escheat or other similar laws) only as general creditors thereof with respect to the Merger Consideration payable upon due surrender of their Certificates and Book-Entry Shares. The Surviving Corporation shall pay all charges and expenses, including those of the Paying Agent, in connection with the exchange of Shares for the Merger Consideration. Notwithstanding any provision of this Agreement to the contrary, none of the parties hereto, the Surviving Corporation or the Paying Agent shall be liable to any person for Merger Consideration delivered to a public official pursuant to any applicable abandoned property, escheat or similar law. All cash paid upon the surrender of Certificates and the rights under the CVRs in accordance with the terms of this Article II shall be deemed to be in full satisfaction of all rights pertaining to the Shares formerly represented by such Certificates.

(e) After 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 that were outstanding prior to the Effective Time. If, after the Effective Time, Certificates are presented to the Surviving Corporation for transfer such Certificates shall be canceled and exchanged for the consideration provided for, and in accordance with the procedures set forth, in this Article II.

(f) Notwithstanding anything in this Agreement to the contrary, the Parent Group, the Surviving Corporation and the Paying Agent shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement any amount as may be required to be deducted and withheld with respect to the making of such payment under applicable Tax laws. To the extent that amounts are so withheld by the Parent Group, the Surviving Corporation or the Paying Agent, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of Shares in respect of whom such deduction and withholding was made by the Parent Group or the Paying Agent.

(g) In the event that any Certificate shall have been lost, stolen or destroyed, upon the holder’s compliance with the replacement requirements established by the Paying Agent, including, if necessary, the posting by the holder of a bond in customary amount as indemnity against any claim that may be made against it or the Surviving Corporation with respect to the Certificate, the Paying Agent will deliver in exchange for the lost, stolen or destroyed Certificate the applicable Merger Consideration payable in respect of the Shares represented by such Certificate pursuant to this Article II.

Section 2.4. CVRs.

(a) The CVRs will be uncertificated contract rights and will be non-assignable and non-transferable by any holder thereof, except with respect to such rights as required by any applicable community property laws or laws of descent and distribution.

(b) The CVRs will become effective at the Effective Time and will expire at 11:59 p.m. New York City time on the earlier of (i) July 11, 2012 and (ii) the consummation of a Company Stock Sale or a Company Merger (the earlier of such dates, the “Maturity Date”). However, if after the Effective Time and prior to July 11, 2012, the Surviving Corporation or any of its Affiliates (the “Permitted Holders”) enters into a definitive agreement providing for a Company Sale (a “Sale Contract”), the Maturity Date shall not be the date specified in the sentence above, but shall be the later of (i) July 11, 2012 and (ii) the date the Company Sale pursuant to such Sale Contract is consummated or terminated.

(c) If there is consummated after the Effective Time and on or before the Maturity Date one or more Company Sales which result in a CVR Distribution Amount greater than zero (0), then, following the Maturity Date, the Parent Group will deposit, or cause to be deposited, with the Paying Agent for payment, subject to any applicable withholding taxes, pro rata to each holder of a CVR, an amount per CVR (the “CVR Consideration”) equal to such CVR Distribution Amount and upon such deposit, subject solely to Section 2.4(e), the CVRs shall be automatically cancelled and be of no further force or effect and no further consideration shall be deliverable by the Parent Group in respect thereof.

(d) If, on the Maturity Date, (i) no Company Sale has been consummated following the Effective Time and on or prior to the Maturity Date, or (ii) if one or more Company Sales has been consummated following the Effective Time and on or prior to the Maturity Date, and the CVR Distribution Amount is zero (0) or less, the CVRs shall automatically terminate and be of no further force or effect and no consideration shall be deliverable in respect thereof.

(e) All computations and determinations relating to the CVRs shall be made by the Parent Group in good faith. Promptly after the Maturity Date, the Parent Group shall notify holders of CVRs in writing of the Parent Group’s determination as to (i) whether any Company Sale occurred after the Effective Time and on or before the Maturity Date, (ii) the aggregate amount of any Net Proceeds received in respect thereof, (iii) the amount (if any) of any resulting CVR Distribution Amount, and (iv) the amount of CVR Consideration (if any) due and payable to CVR holders under this Agreement ((i) through (iv) collectively, the “Relevant Determinations”). Following such notice, CVR holders shall have 90 days to communicate to the Parent Group in writing any objections to the Parent Group’s determination of the Relevant Determinations; provided, that, a CVR holder may object to the Parent Group’s determinations only (A) on the basis that the Parent Group’s determinations, including determinations regarding fair market value in the definition of “Net Proceeds” being made in good faith, were not made in accordance with the terms hereof, (B) to the extent that, if such holder’s objection was upheld, the Parent Group would be required to pay an aggregate of at least $200,000 more in CVR Consideration than according to the Parent Group’s determinations and (C) if the bases for such holder’s objection are specified in writing and in reasonable detail (such writing, an “Objection Notice”). If the Parent Group receives one or more Objection Notices, then the Parent Group and the CVR holders who delivered such Objection Notice shall discuss the objections set forth therein in good faith and the Parent Group agrees, and each CVR holder by accepting a CVR agrees, to use all reasonable efforts to ensure that any final resolution of such objections will be applicable to, and binding on, all CVR holders (and not only those CVR holders who objected to Parent Group’s determinations). If additional amounts are paid in settlement of one or more Objection Notices, then all objecting and non-objecting CVR holders shall, to the extent practicable, be treated equally by the Parent Group and receive the same amount and form of consideration as the objecting CVR holders, based on and in proportion to the number of CVRs held by each such holder. If any such objections are not resolved by the date that is 150 days after the Maturity Date, then the Parent Group and the CVR holders shall submit the matter to the Court of Chancery of the State of Delaware (the “Delaware Court of Chancery”).

(f) The holder of a CVR will not be entitled to any of the rights of a stockholder in the Parent Group or the Surviving Corporation or any of their respective Affiliates (including, without limitation, voting and dividend rights). None of the Parent Group or any of its Affiliates or Subsidiaries shall be liable to any person in respect of any CVR Consideration delivered to a public official pursuant to any applicable abandoned property, escheat or similar law.

(g) BY ACCEPTING A CVR, EACH CVR HOLDER HEREBY (I) IRREVOCABLY WAIVES ANY RIGHTS TO TRIAL BY JURY IN ANY LEGAL PROCEEDING RELATED TO THE CVRS, (II) CONSENTS TO SUBMIT TO THE PERSONAL JURISDICTION OF THE DELAWARE COURT OF CHANCERY AND ANY STATE APPELLATE COURT THEREFROM WITHIN THE STATE OF DELAWARE (UNLESS THE DELAWARE COURT OF CHANCERY SHALL DECLINE TO ACCEPT JURISDICTION OVER A PARTICULAR MATTER, IN WHICH CASE, IN ANY FEDERAL COURT LOCATED WITHIN THE STATE OF DELAWARE), IN THE EVENT ANY DISPUTE ARISES OUT OF THE CVRS OR ANY OF THE TRANSACTIONS CONTEMPLATED BY THE CVRS, (III) AGREES NOT TO ATTEMPT TO DENY OR DEFEAT SUCH PERSONAL JURISDICTION BY MOTION OR OTHER REQUEST FOR LEAVE FROM ANY SUCH COURT, (IV) AGREES NOT TO BRING ANY ACTION RELATING TO THE CVRS OR ANY OF THE TRANSACTIONS CONTEMPLATED BY THE CVRS IN ANY COURT OTHER THAN SAID COURTS OF THE STATE OF DELAWARE AS DESIGNATED ABOVE, AND (V) CONSENTS TO SERVICE BEING MADE THROUGH THE NOTICE PROCEDURES SET FORTH IN SECTION 8.2.

Section 5.3. Directors’ and Officers’ Indemnification and Insurance.

(a) Without limiting any additional rights under any existing agreement or arrangement, from the Effective Time through the sixth anniversary of the date on which the Effective Time occurs, the Parent Group shall, and shall cause the Surviving Corporation to, indemnify and hold harmless each present (as of the Effective Time) and former officer and director of the Company and its Subsidiaries (the “Indemnified Parties”), against all claims, losses, liabilities, damages, judgments, inquiries, fines and reasonable fees, costs and expenses, including attorneys’ fees and disbursements (collectively, “Losses”), incurred in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, arising out of or pertaining to (i) the fact that an Indemnified Party is or was an officer or director of the Company or any of its Subsidiaries or (ii) matters existing or occurring at or prior to the Effective Time (including this Agreement and the transactions and actions contemplated hereby), whether asserted or claimed prior to, at or after the Effective Time, to the fullest extent permitted under applicable law. In the event of any such claim, action, suit, proceeding or investigation, (A) each Indemnified Party will be entitled to advancement of expenses incurred in the defense of any claim, action, suit, proceeding or investigation from the Surviving Corporation within ten (10) Business Days of receipt by the Parent Group or the Surviving Corporation from the Indemnified Party of a request therefor, (B) neither Parent Group nor the Surviving Corporation shall settle, compromise or consent to the entry of any judgment in any proceeding or threatened action, suit, proceeding, investigation or claim (and in which indemnification could be sought by such Indemnified Party hereunder), unless such settlement, compromise or consent includes an unconditional release of such Indemnified Party from all liability arising out of such action, suit, proceeding, investigation or claim or such Indemnified Party otherwise consents, and (C) each of the Surviving Corporation and the Indemnified Party shall cooperate in the defense of any such matter. The Parent Group or the Surviving Corporation shall have the right, but not the obligation, to assume and control the defense of any threatened or actual claim, action, suit, proceeding or investigation relating to any acts or omissions covered under this Section 5.3 unless there is a conflict of interest between the Parent Group and the Surviving Corporation, on the one hand, and the applicable Indemnified Party, on the other; provided, that, prior to any such assumption and control, the party assuming control of such defense shall provide to the applicable Indemnified Party a written undertaking reaffirming its obligations hereunder, under the organizational documents of the Company and the Surviving Corporation to indemnify such party against any and all Losses relating thereto or resulting therefrom.

(b) The certificate of incorporation and bylaws of the Surviving Corporation shall contain provisions no less favorable with respect to indemnification, advancement of expenses and exculpation of former or present directors and officers than are set forth in the Company’s Certificate of Incorporation and Bylaws, which provisions shall not be amended, repealed or otherwise modified for a period of six years from the Effective Time in any manner that would adversely affect the rights thereunder of any such individuals.

(c) Prior to the Effective Time, the Company shall and, if the Company is unable to, the Parent Group shall cause the Surviving Corporation as of the Effective Time to, obtain and fully pay the premium for the extension of (i) the directors’ and officers’ liability coverage of the Company’s existing directors’ and officers’ insurance policies, and (ii) the Company’s existing fiduciary liability insurance policies, in each case for a claims reporting or discovery period of at least six years from and after the Effective Time from an insurance carrier with the same or better credit rating as the Company’s current insurance carrier with respect to directors’ and officers’ liability insurance and fiduciary liability insurance (collectively, “D&O Insurance”) with terms, conditions, retentions and limits of liability that are at least as favorable, in the aggregate, as the Company’s existing policies with respect to any actual or alleged error, misstatement, misleading statement, act, omission, neglect, breach of duty or any matter claimed against a director or officer of the Company or any of its Subsidiaries by reason of him or her serving in such capacity that existed or occurred at or prior to the Effective Time (including in connection with this Agreement or the transactions or actions contemplated hereby); provided, however, that, if the annual premium for such insurance shall exceed 300% of the current annual premium (such 300% threshold, the “Maximum Premium”), then the Company or the Parent Group, as applicable, shall provide or cause to be provided a policy for the applicable individuals with the best coverage as shall then be available at an annual premium not in excess of the Maximum Premium. If the Company and the Surviving Corporation for any reason fail to obtain such “tail” insurance policies as of the Effective Time, the Surviving Corporation shall, and the Parent Group shall cause the Surviving Corporation to, continue to maintain in effect for a period of at least six years from and after the Effective Time the D&O Insurance in place as of the date hereof with terms, conditions, retentions and limits of liability that are at least as favorable, in the aggregate, as provided in the Company’s existing policies as of the date hereof, or the Surviving Corporation shall, and the Parent Group shall cause the Surviving Corporation to, use reasonable best efforts to purchase comparable D&O Insurance for such six-year period with terms, conditions, retentions and limits of liability that are at least as favorable, in the aggregate, as provided in the Company’s existing policies as of the date hereof; provided, however, in each case, that, if the annual premium for such insurance shall exceed the Maximum Premium, then the Company or the Parent Group, as applicable, shall provide or cause to be provided a policy for the applicable individuals with the best coverage as shall then be available at an annual premium not in excess of the Maximum Premium.

(d) Notwithstanding anything herein to the contrary, if any claim, action, suit, proceeding or investigation (whether arising before, at or after the Effective Time) is made against any Indemnified Party on or prior to the sixth anniversary of the Effective Time, the provisions and benefits of this Section 5.3 shall continue in full effect until the final disposition of such claim, action, suit, proceeding or investigation.

(e) This covenant is intended to be for the benefit of, and shall be enforceable by, each of the Indemnified Parties and their respective heirs and legal representatives. The indemnification provided for herein shall not be deemed exclusive of any other rights to which an Indemnified Party is entitled, whether pursuant to law, contract or otherwise, including, but not limited to, those under the Indemnification Agreements.

(f) In the event that the Surviving Corporation or the Parent Group 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 corporation or entity of such consolidation or merger or (ii) transfers or conveys all or a majority of its properties and assets to any person, then, and in each such case, proper provision shall be made so that the successors and assigns of the Surviving Corporation or the Parent Group, as the case may be, shall succeed to the obligations set forth in this Section 5.3.

Section 5.4. Further Action; Efforts. Upon the terms and subject to the conditions of this Agreement, each of the parties shall use its commercially reasonable best efforts to (i) take, or cause to be taken, all actions and to do, or cause to be done, and cooperate with each other in order to do, all things necessary, proper or advisable to consummate the transactions contemplated by this Agreement as soon as practicable and (ii) do all things necessary, proper or advisable under applicable laws and regulations to consummate the Merger and the other transactions contemplated by this Agreement at the earliest practicable date, including: (A) causing the preparation and filing of all forms, registrations and notices required to be filed to consummate the Merger; (B) defending all lawsuits and other proceedings by or before any Governmental Entity challenging this Agreement or the consummation of the Merger; and (C) using commercially reasonable best efforts to prevent the entry of any court order, and to have vacated, lifted, reversed or overturned any injunction, decree, ruling, order or other action of any Governmental Entity that would prevent, prohibit, restrict or delay the consummation of the transactions contemplated by this Agreement. Each of the parties hereto agrees to treat the receipt of the Merger Consideration in exchange for shares of Company stock pursuant to the Merger as a taxable sale and purchase of Company stock for income tax purposes. With respect to any potential withholding tax under Section 1445 of the Internal Revenues Code of 1986, as amended (the “Code”), the parties hereto intend to rely on the exemption from such withholding tax pursuant to Code Section 897(c)(3) with respect to stockholders who beneficially own Common Stock representing less than five percent (5%) ownership in the Company. Promptly after the date hereof, the Company will make a determination as to whether the Company is able to supply a certificate in accordance with Treas. Reg. §1.1445-2(c)(3) that the Company is not a United States real property holding corporation so that no withholding will be required under Code Section 1445. Notwithstanding the foregoing, except as otherwise expressly provided by this Agreement, none of the parties hereto nor any of their respective Affiliates shall be obligated to make any payments or otherwise pay any consideration to any third party to obtain any applicable consent, waiver, settlement or approval in order to consummate the transactions contemplated hereby.

Section 5.5. Public Announcements. Unless and until the earlier of (a) the termination of this Agreement and (b) the Effective Time, the Company and the Parent Group will consult with and provide each other the reasonable opportunity to review and comment upon any press release or other public statement or comment prior to the issuance of such press release or other public statement or comment relating to this Agreement or the transactions contemplated herein and shall not issue any such press release or other public statement or comment prior to such consultation except as such party may be advised by its legal counsel is required by applicable law or by obligations pursuant to any listing agreement with any national securities exchange. The Parent Group and the Company agree that the press release announcing the execution and delivery of this Agreement shall be a joint release of the Parent Group and the Company.

Section 5.6. Notification of Certain Matters. The Company shall give prompt notice to the Parent Group, and the Parent Group shall give prompt notice to the Company, of (a) any notice or other communication received by such party from any Governmental Entity in connection with the Merger or the other transactions contemplated hereby or from any person alleging that the consent of such person is or may be required in connection with the Merger or the other transactions contemplated hereby, if the subject matter of such communication or the failure of such party to obtain such consent could be material to the Company, the Surviving Corporation or the Parent Group or (b) any actions, suits, claims, investigations or proceedings commenced or, to such party’s knowledge, threatened against, relating to or involving or otherwise affecting such party or any of its Subsidiaries or Affiliates which relate to the Merger or the other transactions contemplated hereby.

Section 5.7. Obligations of Merger Sub. The Parent Group shall take all action necessary to cause Merger Sub and the Surviving Corporation to perform their respective obligations under this Agreement.

TO THE FULLEST EXTENT PERMITTED BY LAW, THE PARTIES HERETO HEREBY WAIVE THEIR RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF THIS AGREEMENT OR ANY DEALINGS BETWEEN THEM RELATING TO THE SUBJECT MATTER OF THIS TRANSACTION. THE SCOPE OF THIS WAIVER IS INTENDED TO BE ALL-ENCOMPASSING OF ANY AND ALL DISPUTES THAT MAY BE FILED IN ANY COURT AND THAT RELATE TO THE SUBJECT MATTER OF THIS AGREEMENT, INCLUDING CONTRACT CLAIMS, TORT CLAIMS, BREACH OF DUTY CLAIMS, AND ALL OTHER COMMON LAW AND STATUTORY CLAIMS.

Section 8.10. Headings. The descriptive headings contained in this Agreement are included for convenience of reference only and shall not affect in any way the meaning or interpretation of this Agreement.

Section 8.11. Counterparts. This Agreement may be executed and delivered (including by facsimile, “.pdf,” or other electronic transmission) in one or more counterparts, and by the different parties hereto in separate counterparts, each of which when executed shall be deemed to be an original but all of which taken together shall constitute one and the same agreement.

Section 8.12. Specific Performance. The parties hereby expressly recognize and acknowledge that immediate, extensive and irreparable damage would result, no adequate remedy at law would exist, and damages would be difficult to determine in the event that any provision of this Agreement is not performed in accordance with its specific terms or is otherwise breached. Therefore, in addition to, and not in limitation of, any other remedy available to any party, a party under this Agreement shall be entitled to specific performance of the terms hereof and immediate injunctive relief, without the necessity of proving the inadequacy of money damages as a remedy and without bond or other security being required. Such remedies, and any and all other remedies provided for in this Agreement, shall, however, be cumulative in nature and not exclusive and shall be in addition to any other remedies whatsoever which any party may otherwise have. Each of the parties hereby acknowledges and agrees that it may be difficult to prove damages with reasonable certainty, that it may be difficult to procure suitable substitute performance, and that injunctive relief and/or specific performance will not cause an undue hardship to the parties. Each of the parties hereby further acknowledges that the existence of any other remedy contemplated by this Agreement does not diminish the availability of specific performance of the obligations hereunder or any other injunctive relief. Each party hereby further agrees that in the event of any action by the other party for specific performance or injunctive relief, it will not assert that a remedy at law or other remedy would be adequate or that specific performance or injunctive relief in respect of such breach or violation should not be available on the grounds that money damages are adequate or any other grounds.

Section 8.13. Jurisdiction. Each of the parties hereto (a) consents to submit itself to the personal jurisdiction of (i) the Delaware Court of Chancery and any state appellate court therefrom within the State of Delaware (unless the Delaware Court of Chancery shall decline to accept jurisdiction over a particular matter, in which case, in any federal court located within the State of Delaware), and (ii) any state or federal court sitting in the State of New York, County of New York, including the federal district court for the Southern District of New York in the event any dispute arises out of this Agreement or any of the transactions contemplated by this Agreement, (b) agrees that it will not attempt to deny or defeat such personal jurisdiction by motion or other request for leave from any such court, (c) agrees that it will not bring any action relating to this Agreement or any of the transactions contemplated by this Agreement in any court other than said courts designated above, and (d) consents to service being made through the notice procedures set forth in Section 8.2. Each of the Company, the Parent Group and Merger Sub hereby agrees that service of any process, summons, notice or document by U.S. registered mail to the respective addresses set forth in Section 8.2 shall be effective service of process for any suit or proceeding in connection with this Agreement or the transactions contemplated hereby.

Section 8.14. Interpretation. When reference is made in this Agreement to a Section, such reference shall be to a Section of this Agreement unless otherwise indicated. Whenever the words “include,” “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation.” The words “hereof,” “herein,” “hereby” and “hereunder” and words of similar import when used in this Agreement shall refer to this Agreement as a whole and not to any particular provision of this Agreement. This Agreement shall be construed without regard to any presumption or rule requiring construction or interpretation against the party drafting or causing any instrument to be drafted.

Section 8.15. CVR Distribution Amount Calculations. Since the Tax Allocation Agreement, dated July 25, 2008 (the “Tax Allocation Agreement”), between the Company and Starfire Holding Corporation, by its terms provides that no payments shall be due thereunder after immediately before the Effective Time, in calculating whether a payment is due to the holders of the CVRs pursuant to the terms of this Agreement, no amounts shall be deemed payable to the Company or from the Company as a result of the provisions of the Tax Allocation Agreement. By way of example, attached hereto as Annex A for illustrative purposes only is an sample calculation of the CVR Distribution Amount to be made hereunder.

The designations, relative rights, preferences and limitations of the Undesignated Preferred Stock, and particularly of the shares of each series thereof, may, to the extent permitted by law, be similar to or differ from those of any other series. The Board of Directors of the Corporation is hereby expressly granted authority, subject to the provisions of this paragraph 4, to fix, from time to time before issuance thereof, the number of shares in each series and all designations, relative rights, preferences and limitations of the shares in each such series, including, but without limiting the generality of the foregoing, the following:

the designation of the series and the number of shares to constitute each series;

(ii)

(iii)

All shares of Undesignated Preferred Stock of the same series shall be identical in all respects, except that shares of any one series issued at different times may differ as to dates, if any, from which dividends thereon may accumulate. All shares of Undesignated Preferred Stock of all series shall be of equal rank and shall be identical in all respects except that any series may differ from any other series with respect to any one or more of the designations, relative rights, preferences and limitations described or referred to in subparagraphs (i) to (ix) inclusive above.

5. The Board of Directors shall have the power to adopt, amend or repeal the by-laws.

6. To the fullest extent permitted under federal law of the United States and the laws of the State of Delaware:

The Corporation shall indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit of proceeding, whether civil, criminal, administrative or investigative by reason of the fact that he or she is or was a director, officer, employee or agent of the Corporation, or is or was serving at the request of the Corporation as a director, officer, trustee, employee or agent of or in any other capacity with another corporation, partnership joint venture, trust or other enterprise, against expenses (including attorneys’ fees and costs), judgments, fines and amounts paid in settlement actually and reasonably incurred by him or her in connection with such action, suit or proceeding if he or she acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the Corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful. The termination of any action, suit or proceeding by judgment, order, settlement, conviction, or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption that the person did not act in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the Corporation, and, with respect to any criminal action proceeding, had reasonable cause to believe that his or her conduct was unlawful.

Expenses incurred in defending a civil or criminal action, suit or proceeding shall (in the case of any action, suit or proceeding against a director of the Corporation) or may (in the case of any action, suit or proceeding against an officer, trustee, employee or agent) be paid by the Corporation in advance of the final disposition of such action, suit or proceeding as authorized by the Board of Directors upon receipt of an undertaking by or on behalf of the indemnified person to repay such amount if it shall ultimately be determined that he or she is not entitled to be indemnified by the Corporation as authorized in this paragraph 6.

The indemnification and other rights set forth in this paragraph 6 shall not be exclusive of any provisions with respect thereto in the bylaws or any other contract or agreement between the Corporation and any officer, director, employee or agent of the Corporation. Neither the amendment nor repeal of this paragraph 6, nor the adoption of any provision of this Certificate of Incorporation inconsistent with this paragraph 6, shall eliminate or reduce the effect of this paragraph 6, in respect of any matter occurring before such amendment, repeal or adoption of an inconsistent provision or in respect of any cause of action, suit or claim relating to any such matter which would have given rise to a right of indemnification or right to receive expenses pursuant to this paragraph 6, if such provision had not been so amended or repealed or if a provision inconsistent therewith had not been so adopted.

7. A director shall have no liability to the Corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, except for any breach of the director’s duty of loyalty to the Corporation or its stockholders, acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law by the director, conduct violating section 174 of the General Corporation Law or for any transaction from which the director will personally receive a benefit in money, property or services to which the director is not legally entitled. If the General Corporation Law is hereafter amended to authorize corporate action further eliminating or limiting the personal liability of directors then the liability of a director shall be eliminated or limited to the full extent permitted by the General Corporation Law, as so amended. Any repeal or modification of this paragraph 7 shall not adversely affect any right or protection of a director of the Corporation existing at the time of such repeal or modification for or with respect to an act or omission of such director occurring prior to such repeal or modification.

8. The Corporation hereby elects not to be governed by Section 203 of the General Corporation Law as from time to time in effect or any successor provision thereto.

9. The books of the Corporation may be kept (subject to any provision contained in the General Corporation Law) outside the State of Delaware at such place as may be designated from time to time by the Board of Directors or the bylaws of the Corporation.

IN WITNESS WHEREOF, the undersigned, being a duly authorized officer of the Corporation, has executed, signed and acknowledged this amended and restated certificate of incorporation on this __ day of ____, 201__.
