AGREEMENT AND PLAN OF MERGER

AGREEMENT AND PLAN OF MERGER, dated as of June 26, 2007 (this “Agreement”), among Basell AF, a Luxembourg entity (“Parent”), BI Acquisition Holdings Limited, a Delaware corporation and a wholly-owned subsidiary of Parent (“Merger Sub”), and Huntsman Corporation, a Delaware corporation (the “Company”).

WHEREAS, the respective Boards of Directors of the Company, the Parent and Merger Sub have approved and declared advisable, this Agreement and the merger of Merger Sub with and into the Company (the “Merger”), on the terms and subject to the conditions provided for in this Agreement;

WHEREAS, Parent, Merger Sub and the Company desire to make certain representations, warranties, covenants and agreements in connection with the Merger and the other transactions contemplated by the Transaction Agreements (collectively, the “Transactions”) and also to prescribe various conditions to the Merger and the other Transactions; and

WHEREAS, contemporaneously with the execution of this Agreement, as an inducement to Parent’s willingness to enter into this Agreement and incur the obligations set forth herein, certain of the Company’s stockholders, which beneficially or of record hold an aggregate of approximately 58.6% of the outstanding shares of Company Common Stock, have entered into a Voting Agreement, dated as of the date hereof, with Parent, pursuant to which, upon the terms set forth therein, such stockholders have agreed to vote their shares of Company Common Stock in favor of this Agreement and the Transactions.

NOW, THEREFORE, in consideration of the foregoing and the representations, warranties, covenants and agreements herein contained, the parties to this Agreement agree as follows:

ARTICLE I

THE MERGER

1.1 The Merger; Effective Time of the Merger. Upon the terms and subject to the conditions of this Agreement, at the Effective Time, Merger Sub shall be merged with and into the Company in accordance with provisions of the General Corporation Law of the State of Delaware (the “DGCL”). As soon as practicable on the Closing Date, at the closing of the Merger (the “Closing”), the parties hereto shall cause the Merger to be consummated by filing a certificate of merger prepared and executed in accordance with the relevant provisions of the DGCL (the “Certificate of Merger”) with the Office of the Secretary of State of the State of Delaware. The Merger shall become effective upon the filing of the Certificate of Merger with the Office of the Secretary of State of the State of Delaware (the date and time of the filing of the Certificate of Merger with the Secretary of State of the State of Delaware, or such later time as agreed upon by Parent and the Company and specified in the Certificate of Merger, the “Effective Time”).

1.2 Closing. The Closing shall take place at 9:30 a.m., Houston, Texas time, on a date that is two Business Days following the satisfaction or (to the extent permitted by applicable law) waiver in accordance with this Agreement of the last to occur of the conditions set forth in ARTICLE VI (other than (i) any such conditions which by their nature cannot be satisfied until the Closing Date, which shall be required to be so satisfied or (to the extent permitted by applicable law) waived in accordance with this Agreement on the Closing Date and (ii) the condition set forth in Section 6.2(d)) (such date being, the “First Eligible Closing Date”) at the offices of Vinson & Elkins L.L.P. in Houston, Texas, or such other place as Parent and the Company may agree in writing. Notwithstanding the foregoing, at the option of the Parent (the “Parent Closing Option”) the Closing may take place on a date that is the earlier of (a) a Business Day on or after the First Eligible Closing Date during the Marketing Period to be specified by Parent on no less than five Business Days notice to the Company and (b) the final day of the Marketing Period. The “Closing Date” shall mean the date on which the Closing occurs. “Business Day” shall mean a day other than a day on which banks in the State of New York or the State of Delaware are authorized or obligated to be closed. “Marketing Period” shall mean the period commencing on the First Eligible Closing Date and ending on the earlier to occur of (i) the 20th Business Day thereafter, and (ii) the last Business Day prior to the Termination Date. If Parent elects to exercise the Parent Closing Option, then from and after the First Eligible Closing Date, the conditions in Section 6.2(a), Section 6.2(b), and Section 6.2(e) shall be deemed to have been satisfied. If the Closing is scheduled to occur on a date other than a Business Day, then the Closing shall occur on the immediately following Business Day.

1.3 Effect of the Merger. At the Effective Time, Merger Sub shall be merged with and into the Company and the separate existence of Merger Sub shall cease and the Company shall continue its existence under the laws of the State of Delaware as the surviving corporation (in such capacity, the Company is sometimes referred to herein as the “Surviving Corporation”). The Merger shall have the effects set forth in this Agreement and the applicable provisions of the DGCL.

1.4 Certificate of Incorporation and Bylaws. At the Effective Time and subject to Section 5.6(b), (a) the Certificate of Incorporation of the Surviving Corporation shall be amended to read in its entirety in the form of Exhibit A hereto, and, as so amended, such Certificate of Incorporation shall be the Certificate of Incorporation of the Surviving Corporation until thereafter amended in accordance with its terms and applicable law; and (b) the Bylaws of Merger Sub shall be the Bylaws of the Surviving Corporation until thereafter amended in accordance with their terms and applicable law.

1.5 Directors and Officers. From and after the Effective Time, the directors of Merger Sub shall be the directors of the Surviving Corporation, and such directors shall serve until their successors have been duly elected or appointed and qualified or until their death, resignation or removal in accordance with the Certificate of Incorporation and Bylaws of the Surviving Corporation. The officers of the Company immediately prior to the Effective Time shall be the officers of the Surviving Company, each to hold office until the earlier of their resignation or removal.

ARTICLE II

EFFECT OF THE MERGER ON THE CAPITAL STOCK OF THE COMPANY AND MERGER SUB; EXCHANGE OF CERTIFICATES

2.1 Effect of the Merger on Capital Stock. At the Effective Time, by virtue of the Merger and without any action on the part of any party or the holder of any of the following securities:

(a) Capital Stock of Merger Sub. Each share of capital stock of Merger Sub issued and outstanding immediately prior to the Effective Time shall be converted into and shall represent one share of common stock, par value $0.01 per share, of the Surviving Corporation, so that, after the Effective Time, Parent shall be the holder of all of the issued and outstanding shares of the Surviving Corporation’s common stock.

(b) Capital Stock of the Company.

(i) Subject to the other provisions of this ARTICLE II, each share of common stock of the Company, par value $0.01 per share (“Company Common Stock”), issued and outstanding immediately prior to the Effective Time (excluding any shares of Company Common Stock described in clause (ii) of this Section 2.1(b) and any Appraisal Shares), including for the avoidance of doubt any shares of Company Common Stock outstanding immediately prior to the Effective Time (x) that were issued upon the conversion of the 5% Mandatory Convertible Preferred Stock of the Company, par value $0.01 per share (the “5% Preferred Stock”) or (y) whose prior restrictions have lapsed pursuant to Section 2.4, shall be converted into the right to receive $25.25 in cash, without interest (the “Merger Consideration”). All such shares of Company Common Stock, when so converted, shall cease to be outstanding and shall automatically be canceled and cease to exist. Each holder of a certificate previously representing any such shares of Company Common Stock shall cease to have any rights with respect thereto, except the right to receive the Merger Consideration.

(ii) All shares of 5% Preferred Stock issued and outstanding immediately prior to the Effective Time (excluding any shares described in clause (iii) of this Section 2.1(b)) shall remain outstanding and be entitled to the rights and privileges set forth in the Certificate of Incorporation of the Company.

(iii) Subject to Section 5.14, all shares of Company Common Stock or 5% Preferred Stock held by the Company as treasury shares or by Parent or Merger Sub or by any Subsidiary of Parent, Merger Sub or the Company, in each case immediately prior to the Effective Time, shall automatically be canceled and cease to exist as of the Effective Time without any conversion thereof, and no consideration shall be delivered or deliverable therefor.

(c) Impact of Stock Splits, Etc. In the event of any change in the number of shares of Company Common Stock, or securities convertible or exchangeable into or exercisable for shares of Company Common Stock (including Company Stock Options), issued

and outstanding between the date of this Agreement and the Effective Time by reason of any stock split, stock dividend, subdivision, reclassification, recapitalization, combination, exchange of shares or the like, the Merger Consideration to be paid for each share of Company Common Stock (or Option Consideration to be paid for any Company Stock Option, as the case may be) as provided in this Agreement shall be appropriately adjusted to provide the holders of Company Common Stock the same economic effect as contemplated by this Agreement prior to such action and, as so adjusted, shall, from and after the date of such event, be the Merger Consideration or the Option Consideration, as the case may be, subject to further adjustment in accordance with this Section 2.1(c).

2.2 Appraisal Rights. Notwithstanding anything in this Agreement to the contrary, shares of Company Common Stock issued and outstanding immediately prior to the Effective Time that are held by any record holder (excluding any shares described in Section 2.1(b)(iii)) who is entitled to demand and properly demands appraisal of such shares pursuant to, and who complies in all respects with, the provisions of Section 262 of the DGCL (the “Appraisal Shares”) shall not be converted into the right to receive the Merger Consideration payable pursuant to Section 2.1(b), but instead, at the Effective Time, the holders of Appraisal Shares shall become entitled to payment of the fair value of such shares in accordance with the provisions of Section 262 of the DGCL and at the Effective Time, all Appraisal Shares shall no longer be outstanding and shall automatically be canceled and cease to exist and the holder of such shares shall cease to have any rights with respect thereto, except as set forth in this Section 2.2. Notwithstanding the foregoing, if any such holder shall fail to perfect or otherwise shall waive, withdraw or lose the right to appraisal under Section 262 of the DGCL or a court of competent jurisdiction shall determine that such holder is not entitled to the relief provided by Section 262 of the DGCL, then the right of such holder to be paid the fair value of such holder’s Appraisal Shares under Section 262 of the DGCL shall be forfeited and cease and each of such holder’s Appraisal Shares shall be deemed to have been converted at the Effective Time into, and shall have become, the right to receive, without interest thereon, the Merger Consideration. The Company shall deliver prompt notice to Parent of any notice received by the Company of intent to demand and of any demands received by the Company for appraisal of any shares of Company Common Stock, attempted withdrawals of such demands and any other instruments served pursuant to the DGCL that are received by the Company for appraisal of any shares of Company Common Stock, and provide Parent with the opportunity to participate in and control all negotiations and proceedings with respect to demands for appraisal under the DGCL. Prior to the Effective Time, the Company shall not, without the prior written consent of Parent, make any payment with respect to, or settle or offer to settle, any such demands, or agree to do any of the foregoing.

2.3 Treatment of Company Options. The Company agrees that it will take such actions as are necessary to cause at the Effective Time each option for the purchase of Company Common Stock then outstanding (“Company Stock Option”), whether or not exercisable, under the Company’s Stock Incentive Plan (the “Company Stock Plan”), to become fully exercisable (if not then fully exercisable), and such options shall immediately thereafter be cancelled and shall automatically cease to exist, and each holder of Company Stock Options shall cease to have any rights with respect to such Company Stock Option except the right to receive the following consideration upon delivery of an option surrender agreement, which shall be in a form reasonably agreed to by Parent and the Company prior to the Closing (“Option

Surrender Agreement”) in accordance with Section 2.5(b)(i)(B): for each share of Company Common Stock subject to such Company Stock Option, an amount in cash (without interest) equal to the excess, if any, of (i) the Merger Consideration payable in respect of a share of Company Common Stock over (ii) the per share exercise price of such Company Stock Option (such amount in cash as described above being hereinafter referred to as the “Option Consideration”). Parent and Merger Sub acknowledge and agree that the actions described in the preceding sentence shall occur at the Effective Time without any action on the part of Merger Sub, Parent or any of their respective stockholders.

2.4 Treatment of Restricted Company Common Stock. Immediately prior to the Effective Time, the restrictions applicable to each share of restricted Company Common Stock (including Company Common Stock underlying restricted stock units and phantom stock) issued or granted pursuant to the Company Stock Plan shall immediately lapse, and, at the Effective Time, each share of such Company Common Stock, restricted stock units and phantom stock shall be converted into the right to receive the Merger Consideration in accordance with the terms hereof.

2.5 Payment for Securities.

(a) Paying Agent; Payment Fund. Prior to the Effective Time, Merger Sub shall enter into an agreement with an entity designated by Parent and reasonably acceptable to the Company to act as agent for the holders of Company Common Stock and holders of the Company Stock Options in connection with the Merger (the “Paying Agent”) and to receive the Merger Consideration and the Option Consideration to which such holders shall become entitled pursuant to this ARTICLE II. On the Closing Date and prior to the filing of the Certificate of Merger, Parent shall deposit, or cause to be deposited, with the Paying Agent, for the benefit of the holders of shares of Company Common Stock and Company Stock Options, for payment in accordance with this ARTICLE II through the Paying Agent, cash in an amount sufficient to permit payment of the aggregate Merger Consideration payable pursuant to Section 2.1 and the aggregate Option Consideration payable pursuant to Section 2.3 (the “Payment Fund”). The Paying Agent shall, pursuant to irrevocable instructions, deliver the Merger Consideration payable pursuant to Section 2.1 and the Option Consideration payable pursuant to Section 2.3, in each case, out of the Payment Fund. The Payment Fund shall be invested by the Paying Agent, as directed by Parent, 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 or in commercial paper obligations rated A-1 or P-1 or better by Moody’s Investors Service, Inc. or Standard & Poor’s Corporation, respectively; provided, however, that any interest or other income resulting from the investment of the Payment Fund shall be solely for the account of Parent or the Surviving Corporation. If for any reason (including losses) the Payment Fund is inadequate to pay the amounts to which holders of shares of Company Common Stock and Company Stock Options shall be entitled under Section 2.1 and Section 2.3, respectively, Parent shall take all steps necessary to enable or cause the Surviving Corporation promptly to deposit additional cash with the Paying Agent sufficient to make all payments required under this Agreement, and Parent and the Surviving Corporation shall in any event be liable for payment thereof. The Payment Fund shall not be used for any other purpose. The Surviving Corporation shall pay all charges and expenses of the Paying Agent in connection with the exchange of shares for the Merger Consideration and the

cancellation of Company Stock Options for the Option Consideration. Any interest or other income resulting from Investment of the Payment Fund shall become part of the Payment Fund.

(b) Payment Procedures.

(i) As soon as practicable after the Effective Time, Parent shall cause the Paying Agent to deliver:

(A) to each record holder, as of immediately prior to the Effective Time, of (1) an outstanding certificate or certificates which immediately prior to the Effective Time represented shares of Company Common Stock (the “Certificates”) or (2) shares of Company Common Stock represented by book-entry (“Book-Entry Shares”), a customary letter of transmittal (“Letter of Transmittal”) (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon proper delivery of the Certificates to the Paying Agent or, in the case of Book-Entry Shares, upon adherence to the procedures set forth in the Letter of Transmittal, and which shall be in a customary form and agreed to by Parent and the Company prior to the Closing) and instructions for use in effecting the surrender of the Certificates or, in the case of Book-Entry Shares, the surrender of such shares, for payment of the Merger Consideration set forth in Section 2.1(b)(i); and

(B) to each holder of a Company Stock Option as of the Effective Time (1) an Option Surrender Agreement, and (2) instructions for use in effecting the surrender of such Company Stock Option in exchange for the Option Consideration.

(ii) Upon surrender to the Paying Agent of a Certificate or Book-Entry Shares, together with the Letter of Transmittal, duly completed and validly executed in accordance with the instructions thereto, and such other customary documents as may be reasonably required by the Surviving Corporation or the Paying Agent, the holder of such Certificate or Book-Entry Shares shall be entitled to receive in exchange therefor the Merger Consideration for each share formerly represented by such Certificate or Book-Entry Shares and such Certificate or book-entry 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. If payment of the Merger Consideration is to be made to an individual, partnership, limited liability company, corporation, joint stock company, trust, estate, joint venture, Governmental Entity, association or unincorporated organization, or any other form of business or professional entity (“Person”), other than the Person in whose name the surrendered Certificate is registered, it shall be a condition of payment that the Certificate so surrendered shall be properly endorsed or shall be otherwise in proper form for transfer 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 surrendered or shall have established to the satisfaction of the Surviving Corporation that such Taxes either have been paid or are not applicable. Until surrendered as contemplated by this

Section 2.5(b)(ii), each Certificate and each Book-Entry Share shall, subject to Section 2.2, be deemed at any time after the Effective Time to represent only the right to receive upon such surrender the Merger Consideration as contemplated by this ARTICLE II.

(iii) Upon cancellation of a Company Stock Option, together with the delivery of the Option Surrender Agreement, duly executed, and any other documents reasonably required by the Surviving Corporation or the Paying Agent, the holder of the Company Stock Option shall be entitled to receive in exchange therefor the amount of cash which such holder has the right to receive pursuant to the provisions of Section 2.3.

(i) All Merger Consideration paid upon the surrender of and in exchange for shares of Company Common Stock in accordance with the terms hereof shall be deemed to have been paid in full satisfaction of all rights pertaining to such Company Common Stock. After the close of business on the date of the Effective Time, there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of the shares of Company Common Stock that were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates or Book-Entry Shares (other than certificates evidencing shares described in clause (ii) of Section 2.1(b)) are presented to the Surviving Corporation for any reason, they shall be canceled and exchanged for the Merger Consideration payable in respect of the shares of Company Common Stock previously represented by such Certificates as provided in this ARTICLE II.

(ii) The cancellation of a Company Stock Option in exchange for the Option Consideration shall be deemed a release of any and all rights the holder had or may have had in respect of such Company Stock Option. Prior to the Effective Time, the Company shall take all action necessary (including causing the Board of Directors of the Company (or any committees thereof) to take such actions as are allowed by the Company Stock Plan) to ensure that, following the Effective Time, without any action required by any holder of Company Options, (A) no participant in the Company Stock Plan or any other plans, programs or arrangements of the Company shall have any right thereunder to acquire or otherwise receive any capital stock of, or other equity or similar interests in, the Company, the Surviving Corporation or any Affiliate (as such term is defined in Rule 405 under the Securities Act, an “Affiliate”) thereof and (B) the Company Stock Options may be cancelled in exchange for the Option Consideration pursuant to the terms of this Agreement.

(d) Termination of Payment Fund. Any portion of the Payment Fund (including any interest thereon) that remains undistributed to the former stockholders or optionholders of the Company on the 365th day after the date on which the Effective Time occurs shall be delivered to Parent or the Surviving Corporation, upon demand by either Parent or the Surviving Corporation, and any former common stockholders or optionholders of the Company who have not theretofore received the Merger Consideration or Option Consideration

to which they are entitled under this ARTICLE II shall thereafter look only to the Surviving Corporation and Parent for payment of their claim for such amounts.

(e) No Liability. None of the Surviving Corporation, Parent, Merger Sub or the Paying Agent shall be liable to any holder of Company Common Stock or Company Stock Option for any amount of Merger Consideration or Option Consideration, as applicable, delivered to a public official pursuant to any applicable abandoned property, escheat or similar law. If any Certificate, Book-Entry Share or Company Stock Option has not been surrendered prior to the time that is immediately prior to the time at which Merger Consideration or Option Consideration in respect of such Certificate, Book-Entry Share or Company Stock Option would otherwise escheat to or become the property of any Governmental Entity, any such shares, cash, dividends or distributions in respect of such Certificate, Book-Entry Share or Company Stock Option shall, to the extent permitted by applicable law, become the property of Parent, free and clear of all claims or interest of any Person previously entitled thereto.

(f) Lost, Stolen, or Destroyed Certificates. If any Certificate (other than a Certificate evidencing shares described in clause (ii) of Section 2.1(b)) 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 reasonably required by Parent or the Surviving Corporation, the posting by such Person of a bond in such reasonable amount as Parent or the Surviving Corporation may direct as indemnity against any claim that may be made against it with respect to such Certificate, the Paying Agent shall issue in exchange for such lost, stolen or destroyed Certificate the amount of Merger Consideration payable in respect of the number of shares of Company Common Stock formerly represented by such Certificate pursuant to the provisions of this ARTICLE II.

(g) Withholding Taxes. Notwithstanding anything in this Agreement to the contrary, Parent, the Surviving Corporation and the Paying Agent shall be entitled to deduct and withhold from the consideration otherwise payable to any holder of Company Common Stock or Company Stock Options pursuant to this Agreement any amount required (or reasonably believed to 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 properly withheld by the Paying Agent, the Surviving Corporation or Parent, as the case may be, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the Company Common Stock or Company Stock Options, as applicable, in respect of which such deduction and withholding was made by the Paying Agent, the Surviving Corporation or Parent, as the case may be.

ARTICLE III

REPRESENTATIONS AND WARRANTIES

3.1 Representations and Warranties of the Company. Except as set forth on the disclosure letter dated as of the date of this Agreement and delivered by the Company to Parent and Merger Sub on or prior to the date of this Agreement (the “Company Disclosure Letter”) and except as disclosed in the Company SEC Documents filed with the SEC prior to the date hereof (other than disclosures in “Disclosure Regarding Forward-Looking Statements” and

“Risk Factors” sections of such Company SEC Documents and only to the extent reasonably apparent in the Company SEC Document that such disclosed item is an event, item or occurrence that constitutes a breach of a representation or warranty set forth in this Section 3.1), the Company represents and warrants to Parent and Merger Sub as follows:

(a) Organization, Standing and Power. Each of the Company and its Subsidiaries is a corporation, partnership or limited liability company duly organized, validly existing and in good standing under the laws of its jurisdiction of incorporation or organization, has all requisite corporate, partnership or limited liability company power and authority to own, lease and operate its properties and to carry on its business as now being conducted, and each of the Company and its Subsidiaries is duly qualified and in good standing to do business in each jurisdiction in which the business it is conducting, or the operation, ownership or leasing of its properties, makes such qualification necessary, other than in such jurisdictions where the failure to qualify or be in good standing would not be reasonably likely to have, individually or in the aggregate, a Company Material Adverse Effect (as defined below). The Company has heretofore made available to Parent complete and correct copies of its Amended and Restated Certificate of Incorporation (the “Company Certificate of Incorporation”), and its Amended and Restated Bylaws (the “Company Bylaws”) as well as the similar organizational documents of each Significant Subsidiary, in each case as of the date hereof.

(m) Labor Matters.

(i) Except as set forth in Schedule 3.1(m)(i) of the Company Disclosure Letter, (A) neither the Company nor any of its Subsidiaries is a party to, or bound by, any collective bargaining agreement or other current labor agreement with any labor union, works council or organization, (B) no labor union, works council or labor organization has made a pending demand for recognition or certification with respect to the Company or any of its Subsidiaries, and there are no representation or certification proceedings or applications seeking a representation or certification proceeding presently pending or, to the knowledge of the Company, threatened in writing to be brought or filed with the National Labor Relations Board or any other labor relations tribunal or authority; and (C) the Company has no knowledge of any labor organizing activities with respect to any employees of the Company or its Subsidiaries.

Neither the Company nor any of its Subsidiaries has received any written notice of the intent of the Equal Employment

Opportunity Commission, the National Labor Relations Board, the Department of Labor or any other Governmental Entity responsible for the enforcement of labor or employment laws to conduct an investigation with respect to the Company or any of its Subsidiaries which such investigation would be reasonably likely to have, individually or in the aggregate, a Company Material Adverse Effect, and no such investigation is in progress.

(iv) The Company and each of its Subsidiaries are, and during the ninety-day period prior to the date of this Agreement, have been in compliance with all notice and other requirements under the Workers’ Adjustment and Retraining Notification Act (the “WARN Act”) and any similar foreign, state or local law, ordinance or regulation of any Governmental Entity relating to plant closings and layoffs.

(v) The Company and each of its Subsidiaries, as applicable are in material compliance with Executive Order 11246.

(vi) To the knowledge of the Company, the Company and each of its Subsidiaries has properly classified, under applicable law, each of its employees as employees, and each of its independent contractors as independent contractors, and has treated each person classified by it as an employee or independent contractor consistently with such status. There is no proceeding pending or, to the knowledge of the Company, threatened against the Company or any of its Subsidiaries challenging the classification of any person as an employee or an independent contractor, including any claim for unpaid benefits, for or on behalf of, any such person other than such proceedings or challenges which would not be reasonably likely to have, individually or in the aggregate, a Company Material Adverse Effect.

(vii) The Company and each of its Subsidiaries has in all material respects withheld and reported all amounts required by law or by agreement to be withheld and reported with respect to wages, salaries, and other payments to employees and is not liable in any material respect for any arrears of wages, compensation or any Taxes, penalties or other sums for failure to comply with any of the foregoing.

The Company and its Subsidiaries own or have the right to use and after the consummation of the transactions contemplated by this Agreement will have the right to use, pursuant to a license or otherwise, all Intellectual Property necessary for the operation of the businesses of each of the Company and its Subsidiaries as presently conducted (collectively, the “Company Intellectual Property”) free and clear of all Encumbrances except for Permitted Encumbrances, except where the failure to own or have the right to use such Intellectual Property would not be reasonably likely to have, individually or in the aggregate, a Company Material Adverse Effect. To the knowledge of the Company, the operation of the business of each of the Company and its Subsidiaries as presently conducted does not infringe upon, violate, or misappropriate any Intellectual Property right of any other Person, except for such matters that would not be reasonably likely to have, individually or in the aggregate, a Company Material Adverse Effect. “Intellectual Property” means all of the following whether arising under the Laws of the United States or of any other jurisdiction: (a) patents, patent applications (including patents issued thereon) and statutory invention registrations, including reissues, divisions, continuations, continuations in part, extensions and reexaminations thereof, and all rights therein provided by international treaties or conventions, (b) trademarks, service marks, trade names, service names, trade dress, logos and other identifiers of source, including all goodwill associated therewith, and any and all common law rights, and registrations and applications for registration thereof, all rights therein provided by international treaties or conventions, and all renewals of any of the foregoing, (c) Internet domain names, (d) copyrightable works, copyrights, moral rights, mask work rights, in each case, whether or not registered, and registrations and applications for registration thereof, and all rights therein provided by international treaties or conventions, (e) confidential and trade secret information, including confidential information regarding inventions, processes, formulae, models, and methodologies.

All such properties and assets are free and clear of all Encumbrances, except for (i) routine statutory liens securing liabilities not yet due and payable, (ii) minor Encumbrances that do not materially detract from the value of the specific asset affected or the present use of such asset, (iii) Encumbrances existing or expressly permitted pursuant to credit facilities of the Company and its Subsidiaries existing as of the date of this Agreement or refinancings or Encumbrances permitted under Section 4.1 hereof (collectively, “Permitted Encumbrances”); and (B) have such ownership or such rights by license,

lease or other agreement to all material equipment used or necessary to conduct their respective businesses as currently conducted.

(p) Environmental Matters.

(i) As used in this Agreement:

(s) Vote Required. The affirmative vote (in person or by proxy) in favor of the adoption of this Agreement of the holders of a majority of the outstanding shares of Company Common Stock entitled to vote thereon is the only vote of the holders of any class or series of the Company’s capital stock necessary to approve and adopt this Agreement and the Merger.

(t) Brokers. Except for the fees and expenses payable to Merrill Lynch & Co. and Cowen and Company, LLC (which amounts have been disclosed to Parent prior to the date hereof), no broker, investment banker, or other Person is entitled to any broker’s, finder’s or other similar fee or commission in connection with the Transactions based upon arrangements made by or on behalf of the Company.

(u) Certain Contracts and Arrangements. Schedule 3.1(u) of the Company Disclosure Letter, together with the lists of exhibits contained in the Company SEC Documents, sets forth a true and complete list, as of the date of this Agreement, of: (i) each agreement to which the Company or any of its Subsidiaries is a party (other than this Agreement) that is of a type that would be required to be included as an exhibit to a Registration Statement on Form S-1 pursuant to Items 601(b)(2), (4), (9) or (10) of Regulation S-K of the SEC if such a registration statement was filed by the Company on the date of this Agreement; (ii) any agreement that purports to limit, in any material respect, the manner in which, or the localities in which, all or any material portion of the business of the Company or its Subsidiaries, taken as a whole, is conducted; (iii) any supply or sales agreement, service agreement or other agreement of a similar nature of one year or greater remaining duration having an aggregate value, or involving payment by or to the Company or any of its Subsidiaries of more than $75 million on an annual basis; (iv) any contract or agreement relating to the borrowing of money or extension of credit pursuant to which the Company or any of its Subsidiaries has a borrowing capacity of more than $15 million or outstanding indebtedness of more than $15 million; (v) each agreement that contains obligations of the Company or its Subsidiaries secured by a lien (other than Permitted Encumbrances), or interest rate or currency hedging agreements, in each case in connection with which the aggregate actual or contingent obligations of the Company and its Subsidiaries under such contract are greater than $15 million; (vi) any contract entered into after January 1, 2006 or not yet consummated, in each case for the acquisition or disposition, directly or indirectly (by merger or otherwise), of businesses or capital stock or other equity interests of another Person for aggregate consideration under such contract in excess of $5 million, but excluding for purposes of this clause (vi) any supply or sales contracts; (vii) any contract pursuant to which the Company or any of its Subsidiaries is burdened from continuing indemnification or other contingent payment obligations related to environmental matters, in each case, that would reasonably be expected to result in payments in excess of $1 million; (viii) Material Real Property Leases; and (ix) any contract between or among the Company or any of its Subsidiaries, on the one hand, and any of their respective Affiliates (other than the Company or any of its Subsidiaries or joint ventures), on the other hand, that involves amounts of more than $1 million other than employment or compensation arrangements with directors or officers or their direct reports (collectively, the “Company Contracts”). Except as would not be

reasonably likely to have, individually or in the aggregate, a Company Material Adverse Effect, neither the Company nor any of its Subsidiaries is in breach or default under any Company Contract nor, to the knowledge of the Company, is any other party to any such Company Contract in breach or default thereunder.

(v) State Takeover Statutes. No “fair price,” “moratorium,” “control share acquisition,” “interested stockholder,” “business combination”, anti-takeover or other similar statute, rule or regulation enacted under state or federal laws in the United States (with the exception of Section 203 of the DGCL (“Section 203”)) applicable to the Company is applicable to this Agreement, the Merger or any of the other Transactions. Assuming the accuracy of the representations made in Section 3.2(h), the action of the Board of Directors of the Company in approving this Agreement is sufficient to render inapplicable to this Agreement, the Merger, and the other Transactions the restrictions on “business combinations” (as defined in Section 203) as set forth in Section 203.

(w) Real Property. Schedule 3.1(w) of the Company Disclosure Letter sets forth a true and complete list, as of the date of this Agreement, of all material real property owned by the Company or any of its Subsidiaries (collectively, the “Owned Real Property”) and for each parcel of Owned Real Property, contains a correct location and description of the business purpose of such Owned Real Property. Schedule 3.1(w) of the Company Disclosure Letter contains a true and complete list, as of the date of this Agreement, of all material real property leased, subleased, licensed or otherwise occupied (whether as tenant, subtenant or pursuant to other occupancy arrangements) by the Company or any Subsidiary of the Company (collectively, including the improvements thereon, the “Material Leased Real Property”), and for each Material Leased Real Property, identifies the location of such Material Leased Real Property. The Owned Real Property and the Material Leased Real Property shall be referred to herein, individually as “Real Property” and, collectively, as the “Real Properties”). The Company and its Subsidiaries have good, valid and defensible title to all Owned Real Property and valid leasehold estates in all Material Leased Real Property free and clear of all Encumbrances, except Permitted Encumbrances, except as would not be reasonably likely to have, individually or in the aggregate, a Company Material Adverse Effect. Each agreement under which the Company or any Subsidiary of the Company is the landlord, sublandlord, tenant, subtenant, or occupant with respect to the Material Leased Real Property (each, a “Material Real Property Lease”) to the knowledge of the Company is in full force and effect and is valid and enforceable against the parties thereto in accordance with its terms, subject, as to enforceability, to bankruptcy, insolvency, reorganization, moratorium and other laws of general applicability relating to or affecting creditors’ rights and to general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law), and neither the Company or any of its Subsidiaries, or to the knowledge of the Company, any other party thereto, has received written notice of any default under any Material Real Property Lease. A true, correct and complete copy of each Material Real Property Lease has been made available to Parent prior to the date hereof. Except as would not be reasonably likely to have, individually or in the aggregate, a Company Material Adverse Effect, there does not exist any pending or, to the knowledge of the Company, threatened, condemnation or eminent domain proceedings that affect any of the Real Properties.

(x) Related Party Transactions. Neither the Company nor any of its Subsidiaries is a party to any contract, agreement or transaction with any director, officer or Affiliate of the Company or any Affiliate of any of the foregoing except for employment or compensation agreements or arrangements with directors and officers and indemnity agreements or provisions in each case made in the ordinary course of business consistent with past practice.

3.2 Representations and Warranties of Parent and Merger Sub. Except as set forth on the disclosure letter dated as of the date of this Agreement and delivered by Parent and Merger Sub to the Company on or prior to the date of this Agreement (the “Parent Disclosure Letter”), Parent and Merger Sub jointly and severally represent and warrant to the Company as follows:

(a) Organization, Standing and Power. Each of Parent and Merger Sub is duly organized, validly existing and in good standing under the laws of its jurisdiction of incorporation or organization, has all requisite corporate power and authority to own, lease and operate its properties and to carry on its business as now being conducted, and is duly qualified and in good standing to do business in each jurisdiction in which the business it is conducting, or the operation, ownership or leasing of its properties, makes such qualification necessary, other than where the failure to be duly organized, validly existing, or so to qualify or be in good standing would not be reasonably likely to have, individually or in the aggregate, a Parent Material Adverse Effect (as defined below). Parent and Merger Sub each has heretofore made available to the Company complete and correct copies of its principle organizational documents. “Parent Material Adverse Effect” means any occurrence, circumstance, condition, change, event or effect that prevents or materially delays or impairs or is reasonably likely to prevent or materially delay or impair the ability of Parent and Merger Sub to consummate the Transactions.

(b) Authority; No Violations, Consents and Approvals.

(i) Each of Parent and Merger Sub has all requisite corporate power and authority to execute and deliver this Agreement and to consummate the Transactions. The execution and delivery of this Agreement by Parent and Merger Sub and the consummation by Parent and Merger Sub of the Transactions have been duly authorized by all necessary corporate action on the part of each of Parent and Merger Sub (other than the adoption of this Agreement by Parent as sole stockholder of Merger Sub, which shall occur immediately after the execution and delivery of this Agreement). This Agreement has been duly executed and delivered by each of Parent and Merger Sub, and, assuming this Agreement constitutes the valid and binding obligation of the Company, constitutes a valid and binding obligation of each of Parent and Merger Sub enforceable in accordance with its terms, subject as to enforceability, to bankruptcy, insolvency, reorganization, moratorium and other laws of general applicability relating to or affecting creditors’ rights and to general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law). Parent, as the owner of all of the outstanding shares of capital stock of Merger Sub, will immediately after the execution and delivery of this Agreement adopt this Agreement in its capacity as sole stockholder of Merger Sub.

(ii) The execution and delivery of this Agreement does not, and the consummation of the Transactions will not result in any violation of, or default (with or without notice or lapse of time, or both) under, or acceleration of any material obligation or the loss of a material benefit under, or result in the creation of any Encumbrance upon any of the properties or assets of Parent or any of its Subsidiaries under any provision of (A) the principle organizational documents of Parent or Merger Sub or any provision of the comparable charter or organizational documents of any of their respective Subsidiaries, (B) any loan or credit agreement, note, bond, mortgage, indenture, lease or other agreement, permit, franchise or license to which Parent or any of its Subsidiaries is a party or by which Parent or Merger Sub or any of their respective Subsidiaries or their respective properties or assets are bound or (C) assuming the consents, approvals, orders, authorizations, registrations, filings, or permits referred to in Section 3.2(b)(iii) are duly and timely obtained or made, any judgment, order, decree, statute, law, ordinance, rule or regulation of any Governmental Entity applicable to Parent or any of its Subsidiaries or any of their respective properties or assets, other than, in the case of clauses (B) and (C), any such violations, defaults, acceleration, losses or Encumbrances that would not be reasonably likely to have, individually or in the aggregate, a Parent Material Adverse Effect.

(iii) No consent, approval, order or authorization of, or registration, or filing with, or permit from, any Governmental Entity is required to be obtained or made by Parent or any of its Subsidiaries in connection with the execution and delivery of this Agreement by Parent and Merger Sub or the consummation by Parent and Merger Sub of the Transactions, including the Financing, except for: (A) the filing of a premerger notification report by Parent under the HSR Act and the expiration or termination of the applicable waiting period with respect thereto; (B) the filing with the SEC of such reports under Section 13(a) of the Exchange Act and such other compliance with the Exchange Act and the rules and regulations thereunder as may be required in connection with this Agreement and the Transactions; (C) the filing of the Certificate of Merger with the Office of the Secretary of State of the State of Delaware; (D) such filings and approvals as may be required by any foreign premerger notification or competition, securities, corporate or other law, rule or regulation of any Governmental Entity set forth on Schedule 3.2(b)(iii) of the Parent Disclosure Letter; and (E) any such consent, approval, order, authorization, registration, filing, or permit that the failure to obtain or would not be reasonably likely to have, individually or in the aggregate, a Parent Material Adverse Effect.

(c) Information Supplied. None of the information supplied or to be supplied by Parent for inclusion or incorporation by reference in the Proxy Statement will, at the date mailed to stockholders of the Company or at the time of the meeting of such stockholders to be held in connection with the Merger, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they are made, not misleading. The Proxy Statement, insofar as it relates to the Parent or its Subsidiaries or Affiliates or other information supplied by the Parent for inclusion therein, in the form mailed to stockholders will comply as to form in all material respects with the provisions of the Exchange Act and the rules and regulations thereunder.

(d) Litigation. There are no suits, claim, actions, proceedings, arbitrations or mediations pending or, to the knowledge of Parent, threatened against Parent or Merger Sub, other than any such suits, claims, actions, proceedings, arbitrations or mediations that would not reasonably be likely to have, individually or in the aggregate, a Parent Material Adverse Effect. Neither Parent nor any of its Subsidiaries nor any of their respective properties or assets is or are subject to any judgments, orders or decrees, except for those judgments, orders or decrees that would reasonably be likely to have, individually or in the aggregate, a Parent Material Adverse Effect.

(e) Financing. Parent and Merger Sub (i) will have at the Effective Time sufficient immediately available funds available and the financial ability to permit Parent and Merger Sub to pay the aggregate Merger Consideration, the aggregate Option Consideration, any repayment or refinancing of debt necessary in connection with the Transactions and fees and expenses of Parent, Merger Sub and their respective Representatives incurred in connection with the Transactions and (ii) at the Effective Time, will have the resources and capabilities (financial and otherwise) to perform its obligations hereunder. True, correct and complete copies of the debt commitment letter dated the date of this Agreement from Citigroup Global Markets Inc. (the “Debt Commitment Letter”), subject to the terms and conditions set forth therein have been provided to the Company. The Debt Commitment Letter has been fully executed and delivered by Citigroup Global Markets Inc. and, when the previously executed signature page of Parent and Merger Sub is released from escrow and delivered, will be valid and enforceable against the parties thereto in accordance with its terms, subject, as to enforceability, to bankruptcy, insolvency, reorganization, moratorium and other laws of general applicability relating to or affecting creditors’ rights and to general principles of equity (regardless of whether such enforceability is considered in a preceding in equity or at law). The obligations of Citigroup Global Markets Inc. to fund the commitment under the Debt Commitment Letter are not subject to any conditions other than as set forth in the Debt Commitment Letter. As of the date of this Agreement, to the knowledge of Parent, no event has occurred that (with or without notice, lapse of time, or both) would constitute a breach or default under the Debt Commitment Letter by Parent or Merger Sub. Parent has no knowledge of any facts or circumstances that are reasonably likely to result in (i) any of the conditions set forth in the Debt Commitment Letter not being satisfied or (ii) the funding contemplated in the Debt Commitment Letter not being made available to Parent on a timely basis in order to consummate the transactions contemplated by this Agreement and any repayment or refinancing of debt necessary in connection with the transactions contemplated by this Agreement.

(f) Solvency; Surviving Corporation After the Merger. Neither Parent nor Merger Sub is entering into the transactions contemplated by this Agreement with the actual intent to hinder, delay or defraud either present or future creditors. Assuming that the representations and warranties of the Company contained in this Agreement are true and correct in all material respects, at and immediately after the Effective Time, and after giving effect to the Merger and the other transactions contemplated hereby, the Surviving Corporation (i) will be solvent (in that both the fair value of its assets will not be less than the sum of its debts and that the present fair saleable value of its assets will not be less than the amount required to pay its probable liability on its debts as they become absolute and matured); (ii) will have adequate capital and liquidity with which to engage in its business; and (iii) will not have incurred debts beyond its ability to pay as they become absolute and matured.

(g) Vote/Approval Required. No vote or consent of the holders of any class or series of capital stock of Parent is necessary to approve this Agreement or the Merger or the other Transactions. The vote or consent of Parent as the sole stockholder of Merger Sub (which has been obtained) is the only vote or consent of the holders of any class or series of capital stock of Merger Sub necessary to approve and adopt this Agreement, the Merger or the other Transactions.

(h) Ownership of Company Capital Stock. Neither Parent nor Merger Sub “own” (within the meaning of Section 203) or have, within the last three years, “owned” any shares of Company Common Stock or 5% Preferred Stock.

(i) Business Conduct.

(i) Merger Sub was incorporated on June 25, 2007. Since its inception, Merger Sub has not engaged in any activity, other than such actions in connection with (A) its organization and (B) the preparation, negotiation and execution of this Agreement and the Transactions.

(ii) There are no Contracts between Parent or Merger Sub, on the one hand, and any member of the Company’s management or directors, on the other hand, as of the date hereof that relate in any way to the Company or the Transactions.

(j) Financial Statements. Parent has made available to the Company a true and correct copy of its consolidated financial statements, including all notes and schedules thereto, for each fiscal quarter and year ended since August 1, 2005 (the “Parent Financial Statements”). The Parent Financial Statements were prepared in accordance with International Financial Reporting Standards applied on a consistent basis during the periods involved (except as may be indicated in the notes thereto) and fairly present in all material respects the financial position of Parent and its consolidated Subsidiaries as of their respective dates and the results of operations and the cash flows of Parent and its consolidated Subsidiaries for the periods presented therein, except that any interim financial statements are subject to normal and recurring year-end adjustments.

(k) Absence of Certain Changes or Events. From December 31, 2006 through the date of this Agreement, there has not been any Parent Material Adverse Effect.

of Adverse Recommendation Change”) from the Company advising Parent that the Board of Directors of the Company intends to take such action and specifying the reasons therefor, including the material terms and conditions of any Superior Proposal that is the basis of the proposed action by such Board of Directors of the Company or any committee thereof (it being understood and agreed that (I) any material amendment to the financial terms of such Superior Proposal shall require a new Notice of Adverse Recommendation Change and a new three Business Day period and (II) in determining whether to make an Adverse Recommendation Change, the Board of Directors of the Company or any committee thereof shall take into account any changes to the financial terms of this Agreement proposed by Parent to the Company in response to a Notice of Adverse Recommendation Change or otherwise). No Adverse Recommendation Change shall change the approval of the Board of Directors of the Company for purposes of causing any share takeover statute to be inapplicable to the transactions contemplated by this Agreement.

The Company shall keep Parent reasonably informed of any material developments with respect to any such Takeover Proposal, request for information or other inquiry (including any material changes thereto).

(e) Notwithstanding anything in this Agreement to the contrary, the Company’s Board of Directors or any committee thereof shall be permitted, at any time prior to obtaining the Company Required Vote, other than in connection with a Takeover Proposal, to make an Adverse Recommendation Change, but only if prior to taking any such action, the Board of Directors of the Company (or any committee thereof) determines in good faith (after consultation with outside legal counsel) that failure to take such action would be inconsistent with its fiduciary duties under applicable law and the Company has given three Business Day advance notice to Parent that the Company intends to take such action.

(f) Notwithstanding anything in this Agreement to the contrary, any factually accurate public statement by the Company that describes the Company’s receipt of a Takeover Proposal and the operation of this Agreement with respect thereto, shall not be deemed

to be a recommendation of such Takeover Proposal or the withdrawal, amendment or modification of the recommendation of the Company’s Board of Directors or the transaction committee thereof in favor of the adoption of this Agreement and the Merger.

(g) Any action pursuant to this Section 4.2(b), (c), (d), (e) shall not constitute a breach of the Company’s representations, warranties, covenants or agreements contained in this Agreement.

(h) “Takeover Proposal” shall mean any inquiry, proposal or offer from any Third Party relating to (a) any direct or indirect acquisition or purchase, in a single transaction or a series of transactions, of (i) any assets of the Company and its Subsidiaries, including capital stock of the Subsidiaries of the Company that generated 15% or more of the Company’s consolidated net revenue or earnings before interest, taxes, depreciation and amortization for the preceding twelve months, or (ii) 15% or more of the outstanding shares of Company Common Stock, (b) any tender offer or exchange offer that, if consummated, would result in any Third Party owning, directly or indirectly, 15% or more of the outstanding shares of Company Common Stock or (c) any merger, consolidation, business combination, recapitalization, liquidation, dissolution, binding share exchange or similar transaction involving the Company pursuant to which any Third Party (or the shareholders of any Third Party) would own, directly or indirectly, 15% or more of the voting capital stock of the Company or of the surviving entity in a merger or the resulting direct or indirect parent of the Company or such surviving entity, other than, in each case, the transactions contemplated by this Agreement. “Company Required Vote” shall mean the affirmative vote of the holders of a majority of the outstanding shares in favor of adoption of this Agreement. “Superior Proposal” shall mean any bona fide Takeover Proposal that if consummated would result in a Third Party (or the shareholders of any Third Party) owning, directly or indirectly, (a) more than 50% of the voting capital stock of the Company or of the surviving entity in a merger or the resulting direct or indirect parent of the Company or such surviving entity or (b) the assets of the Company or any of its Subsidiaries that generated 50% or more of the Company’s consolidated net revenue or earnings before interest, taxes, depreciation and amortization for the preceding twelve months, in either case, the Company’s Board of Directors or a committee thereof determines (after consultation with its financial advisors and outside counsel and after taking into account relevant legal, financial, regulatory, estimated timing of consummation and other aspects of such proposal and the Third Party making such proposal) would, if consummated in accordance with its terms, result in a transaction more favorable to the Company’s stockholders than the Merger. “Third Party” shall mean any Person or group (as defined in Section 13(d)(3) of the Exchange Act) other than Parent, Merger Sub or any Affiliates thereof.

attorney/client or attorney work product privilege or that such access or the furnishing of such information is prohibited by law or an existing contract or agreement, provided, however, that the parties shall use reasonable best efforts to make appropriate substitute arrangements to permit reasonable disclosure under such circumstances. Notwithstanding the foregoing, Parent shall not have access to personnel records of the Company or any of its Subsidiaries relating to individual performance or evaluation records, medical histories or other information that in the Company’s good faith opinion on the advice of outside counsel the disclosure of which could subject the Company or any of its Subsidiaries to risk of liability.

Unless otherwise agreed and without limiting the obligations stated in this Section 5.4(b), Parent and the Company shall each use its reasonable best efforts to ensure the prompt expiration of any applicable waiting period under any Premerger Notification Rules or approval by the relevant Antitrust Authority. Further, without limiting the obligations stated in this Section 5.4(b), Parent and the Company shall each use its reasonable best efforts to respond to and comply with any request for information regarding the Merger or filings under any Premerger Notification Rules from any Governmental Entity charged with enforcing, applying, administering, or investigating any statute, law, ordinance, rule or regulation designed to prohibit, restrict or regulate actions for the purpose or effect of monopolization, restraining trade or abusing a dominant position (collectively, “Antitrust Laws”), including the Federal Trade Commission, the Department of Justice, any attorney general of any state of the United States, the European Commission or any other competition authority of any jurisdiction (“Antitrust Authority”). Parent shall be entitled to direct any proceedings or negotiations with any Antitrust Authority or other Person relating to the foregoing Merger or filings under any Premerger Notification Rules, provided that it shall afford the Company a reasonable opportunity to participate therein. Neither party shall initiate any meeting or discussion with any Governmental Entity with respect to any filings, applications, investigation, or other inquiry regarding the Merger or filings under any Premerger Notification Rules without giving the other party reasonable prior notice of the meeting or discussion and, to the extent permitted by the relevant Governmental Entity, the opportunity to attend and participate (which, at the request of either party, shall be limited to outside antitrust counsel only); provided, however, that the

Company shall not initiate any offer to any Governmental Entity with respect to any proposed Divestiture Action. Notwithstanding anything herein to the contrary, Parent shall take any and all action necessary, including but not limited to (i) selling or otherwise disposing of, or holding separate and agreeing to sell or otherwise dispose of, assets, categories of assets or businesses of the Company or Parent or their respective Subsidiaries; (ii) terminating existing relationships, contractual rights or obligations of the Company or Parent or their respective Subsidiaries; (iii) terminating any venture or other arrangement; (iv) creating any relationship, contractual rights or obligations of the Company or Parent or their respective Subsidiaries or (v) effectuating any other change or restructuring of the Company or Parent or their respective Subsidiaries (and, in each case, to enter into agreements or stipulate to the entry of an order or decree or file appropriate applications with any Antitrust Authority in connection with any of the foregoing and in the case of actions by or with respect to the Company or its Subsidiaries or its or their businesses or assets; by consenting to such action by the Company and provided that any such action may, at the discretion of the Parent, be conditioned upon consummation of the Merger) (each a “Divestiture Action”) to ensure that no Governmental Entity enters any order, decision, judgment, decree, ruling, injunction (preliminary or permanent), or establishes any law, rule, regulation or other action preliminarily or permanently restraining, enjoining or prohibiting the consummation of the Merger, (“Antitrust Prohibition”) or to ensure that no Antitrust Authority with the authority to clear, authorize or otherwise approve the consummation of the Merger, fails to do so by the Termination Date. In the event that any action is threatened or instituted challenging the Merger as violative of any Premerger Notification Rule or other Antitrust Law, Parent shall take all action necessary, including but not limited to any Divestiture Action to avoid or resolve such action. In the event that any permanent or preliminary injunction or other order is entered or becomes reasonably foreseeable to be entered in any proceeding that would make consummation of the transactions contemplated hereby in accordance with the terms of this Agreement unlawful or that would restrain, enjoin or otherwise prevent or materially delay the consummation of the transactions contemplated by this Agreement, Parent shall take promptly any and all steps necessary to vacate, modify or suspend such injunction or order so as to permit such consummation prior to the Termination Date. The parties shall take reasonable efforts to share information protected from disclosure under the attorney-client privilege, work product doctrine, joint defense privilege or any other privilege pursuant to this section so as to preserve any applicable privilege.

(c) Parent and Merger Sub and any of their respective Affiliates shall not take any action with the intention to, or that could reasonably be expected to, hinder or delay the obtaining of clearance or any necessary approval of any Antitrust Authority under an Premerger Notification Rule or Antitrust Law or the expiration of the required waiting period under the Premerger Notification Rules or any other Antitrust Laws, except as may be necessary, in its good faith judgment, to resist or reduce the scope of a Divestiture Action but in no event beyond the Termination Date.

(d) If any Divestiture Action agreed to by Parent requires action by or with respect to the Company or its Subsidiaries or its or their businesses or assets, and such action would constitute a breach of this Agreement, the Parent hereby agrees to consent to the taking of such action by the Company and any such action may, at the discretion of the Company, be conditioned upon consummation of the Merger.

(e) Notwithstanding anything else contained herein, the provisions of this Section 5.4 shall not be construed to require either party to undertake any efforts, or to take or consent to any action if such efforts, action or consent would be reasonably likely to result in a material adverse effect on the business, operations, financial condition or results of operations of the combined business of Parent and the Company after giving effect to the consummation of the transactions contemplated hereby.

5.5 Employee Matters.

(a) Parent or the Surviving Corporation shall take such action as may be necessary so that on and after the Effective Time, and for one year thereafter, officers and employees of the Company and its Subsidiaries not covered by any collective bargaining agreement or labor contract who remain employed after the Closing by Parent, its Subsidiaries, Affiliates or the Surviving Corporation (the “Parent Group”), are provided compensation (including, but not limited to, base salary, base wages, annual and long-term incentive compensation) and benefits (including, but not limited to, pension and welfare benefits but excluding equity compensation) which are, in the aggregate, materially no less favorable than those made available by the Company and its Subsidiaries to its officers and employees immediately prior to the Effective Time. To the extent not duplicative of benefits, for purposes of eligibility to participate, calculation of benefits and vesting in all benefits provided by the Parent Group to officers and employees of the Company and its Subsidiaries, such officers and employees will be credited with their years of benefits eligibility service with the Company and its Subsidiaries and any predecessors thereof to the extent such service with a predecessor was so recognized under analogous Employee Benefit Plans of the Company and its Subsidiaries prior to the Effective Time. The eligibility of any such officer or employee of the Company and its Subsidiaries to participate in any welfare benefit plan or program of the Parent Group shall not be subject to any exclusions for any pre-existing conditions if such individual had met the participation requirements of similar benefit plans and programs of the Company and its Subsidiaries prior to the Effective Time. Amounts paid before the Effective Time by such officers and employees of the Company and its Subsidiaries under any health plans of the Company or its Subsidiaries shall, after the Effective Time, be taken into account in applying deductible and out-of-pocket limits applicable under the health plans of the Parent Group to the same extent as if such amounts had, when paid, been paid under such health plans of the Parent Group. Nothing contained in this Section 5.5 shall create any rights in any officer or employee of the Company or any of its Subsidiaries in respect of continued employment for any specified period of any nature or kind whatsoever or, except as set forth in the following sentence, limit Parent’s or the Surviving Corporation’s power to amend or terminate any particular Employee Benefit Plan or Foreign Benefit Plan or require (and the Company shall take no action that would require) the Parent or Surviving Corporation to continue any particular Employee Benefit Plan or Foreign Benefit Plan. To the extent that an agreement with an entity listed in Schedule 3.1(m)(i) of the Company Disclosure Letter obligates the Company to require a purchaser or merger partner to assume the terms of that agreement, Parent agrees to recognize, and cause the Surviving Corporation to recognize, the entity that is a party to such an agreement as the exclusive bargaining representative of the covered employees and to adopt and cause the Surviving Corporation to adopt, the terms of that agreement and any related and current memorandums of agreement between the Company and such entity as are set forth in Schedule 3.1(m)(i) of the Company Disclosure Letter.

(b) Except as necessary to comply with applicable law, for a period of at least twelve months from the Effective Time, Parent Group shall not terminate or otherwise amend the severance plans described in Schedule 5.5(b) of the Company Disclosure Letter in a manner adverse to any officer or employee of the Company or any of its Subsidiaries covered by such plans immediately prior to the Effective Time.

5.6 Indemnification; Directors’ and Officers’ Insurance.

(a) Without limiting any other rights that any Indemnified Person (as defined below) may have pursuant to any employment agreement or indemnification agreement in effect on the date hereof, from and after the Effective Time through the six year anniversary of the Effective Time, the Surviving Corporation shall indemnify, defend and hold harmless (and Parent shall cause the Surviving Corporation to indemnify, defend and hold harmless) each Person who is now, or has been at any time prior to the date of this Agreement or who becomes prior to the Effective Time, a director or officer of the Company or any of its Subsidiaries or who acts as a fiduciary under any Employee Benefit Plan of the Company or any of its Subsidiaries in their capacity as such and not as stockholder or optionholder of the Company or its Subsidiaries (the “Indemnified Persons”) against all losses, claims, damages, costs, fines, penalties, expenses (including attorneys’ and other professionals’ fees and expenses), liabilities or judgments or amounts that are paid in settlement (with the approval of the indemnifying party), of or incurred in connection with any threatened or actual claim, action, suit, proceeding or investigation to which such Indemnified Person is a party based, in whole or in part, on or arising, in whole or in part, out of the fact that such Person is or was a director or officer of the Company or any of its Subsidiaries, a fiduciary under any Employee Benefit Plan of the Company or any of its Subsidiaries or is or was serving at the request of the Company or any of its Subsidiaries as a director, officer, employee or agent of another corporation, partnership, limited liability company, joint venture, employee benefit plan, trust or other enterprise or by reason of anything done or not done by such Person in any such capacity, pertaining to any act or omission occurring or existing prior to, the Effective Time and whether asserted or claimed prior to, at or after the Effective Time (“Indemnified Liabilities”), including all Indemnified Liabilities based in whole or in part on, or arising in whole or in part out of, or pertaining to, this Agreement or the Transactions, in each case to the fullest extent permitted under applicable law (and the Surviving Corporation shall pay reasonable expenses incurred in defense of any claim in connection therewith in advance of the final disposition of any such claim, action, suit, proceeding or investigation to each Indemnified Person to the fullest extent permitted under applicable law); provided that any person to whom expenses are advanced provides an undertaking to repay such advances if it is ultimately determined that such person is not entitled to indemnification. Without limiting the foregoing, in the event any such claim, action, suit, proceeding or investigation is brought against any Indemnified Persons (whether asserted before or after the Effective Time), (i) the Indemnified Persons may retain the Company’s regularly engaged legal counsel or other counsel satisfactory to them, and Parent and the Surviving Corporation shall pay all reasonable fees and expenses of such counsel for the Indemnified Persons as promptly as statements therefor are received, and (ii) Parent and the Surviving Corporation shall cooperate in the defense of any such matter, provided that neither Parent nor the Surviving Corporation shall be liable for any settlement effected without its prior written consent. Any Indemnified Person wishing to claim indemnification under this Section 5.6, upon learning of any such claim, action, suit, proceeding or investigation, shall notify the Surviving Corporation (but the failure so to

notify shall not relieve a party from any obligations that it may have under this Section 5.6 except to the extent such failure materially prejudices such party’s position with respect to such claims) and, if required by law, shall deliver to the Surviving Corporation an undertaking to repay any amounts advanced to it if it shall ultimately be determined that such Indemnified Person is not entitled to indemnification, but without any requirement for the posting of a bond or any other terms or conditions other than those expressly set forth herein; provided further, that Parent shall not be obligated pursuant to this Section 5.6(a) to pay the fees and disbursements of more than one counsel for all Indemnified Persons in any single action, unless, in the good faith judgment of any of the Indemnified Persons, there is or may be a conflict of interests between two or more of such Indemnified Persons, in which case there may be separate counsel for each similarly situated group.

(b) Except as set forth in Section 1.4, Parent and the Surviving Corporation shall not amend, repeal or otherwise modify the Certificate of Incorporation or Bylaws of the Surviving Corporation in any manner that would affect (or manage the Surviving Corporation or its Subsidiaries, with the intent to) adversely the rights thereunder or under the Company Certificate of Incorporation or Company Bylaws of any Indemnified Person to indemnification, exculpation and advancement except to the extent required by law. Parent shall, and shall cause the Surviving Corporation to, fulfill and honor any indemnification or exculpation agreements between the Company and any of its directors, officers or employees existing immediately prior to the Effective Time.

(c) Parent and the Surviving Corporation shall indemnify any Indemnified Person against all reasonable costs and expenses (including reasonable attorneys’ fees and expenses), relating to the enforcement of such Indemnified Person’s rights under this Section 5.6 or under any charter, bylaw or contract.

(d) Parent agrees that immediately prior to the Effective Time, the Company will cause to be put in place, and Parent shall fully prepay immediately prior to the Effective Time, “tail” insurance policies with a claims period of at least six years from 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 in an amount and scope at least as favorable as the Company’s existing policies with respect to matters, acts or omissions existing or occurring at or prior to the Effective Time; provided, that in no event shall Parent be required to spend more than 200% (the “Cap Amount”) of the last annual premium paid by the Company prior to the date hereof (the amount of such premium being set forth in Schedule 3.1(q) of the Company Disclosure Letter) per policy year of coverage under such tail policy; provided, further that if the cost per policy year of such insurance exceeds the Cap Amount, Parent shall purchase as much coverage per policy year as reasonably obtainable for the Cap Amount.

(e) In the event that the Surviving Corporation or any of its 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 all or substantially all of its properties and assets to any Person, then, in each such case, proper provisions shall be made so that the successors and assigns of the Surviving Corporation shall assume the obligations set forth in this Section 5.6(a). The provisions of this Section 5.6(a) are

intended to be for the benefit of, and shall be enforceable by, the parties hereto and each Person entitled to indemnification or insurance coverage or expense advancement pursuant to this Section 5.6(a), and his heirs and representatives. The Surviving Corporation shall not sell, transfer, distribute or otherwise dispose of any of its assets in a manner that would reasonably be expected to render the Surviving Corporation unable to satisfy its obligations under this Section 5.6(a).

(f) Parent will ensure (including providing funding, if necessary) that the obligations of the Surviving Corporation in this Section 5.6 are fulfilled.

5.7 Agreement to Defend. In the event any claim, action, suit, investigation or other legal or administrative proceeding by any Governmental Entity or other Person is commenced that questions the validity or legality of the Transactions or seeks damages in connection therewith, the parties hereto agree to cooperate and use their reasonable best efforts to defend against and respond thereto. The Company shall give Parent reasonable opportunity to participate in the defense or settlement of any stockholder litigation against the Company and its directors relating to any Transaction, provided, that no such settlement shall be agreed to without Parent’s consent, which shall not be unreasonably withheld, conditioned or delayed.

5.8 Public Announcements. The parties hereto will consult with each other before issuing, and will provide each other reasonable opportunity to review and comment upon, any press release or otherwise making any written public statements with respect to this Agreement, the Merger or the other Transactions, and shall not issue any such press release or make any such written public statement prior to such consultation, except as Parent, Merger Sub or the Company may be required by applicable law, court order or by obligations pursuant to any listing agreement with any national securities exchange (in which case such party will, to the extent practicable, promptly inform the other parties hereto in writing in advance of such compelled disclosure).

5.9 Advice of Certain Matters; Control of Business. Subject to compliance with all applicable laws, the Company and Parent, as the case may be, shall confer on a regular basis with each other, report on operational matters and shall promptly advise each other orally and in writing of any change or event having, or which would be reasonably likely to have, individually or in the aggregate, a Company Material Adverse Effect or Parent Material Adverse Effect, as the case may be. The Company and Parent shall promptly provide each other (or their respective counsel) copies of all filings made by such party or its Subsidiaries with the SEC or any other Governmental Entity in connection with this Agreement and the Transactions. Prior to the Effective Time, the Company shall exercise, consistent with the terms and conditions of this Agreement, complete control and supervision of the Company’s operations.

5.10 Conveyance Taxes. The Company and Parent will (a) cooperate in the preparation, execution and filing of all Tax Returns, questionnaires, applications or other documents regarding any real property transfer or gains, sales, use, transfer, value added, stock transfer and stamp Taxes, any transfer, recording, registration and other fees and any similar Taxes which become payable in connection with the Transactions, (b) cooperate in the preparation, execution and filing of all applications or other documents regarding any applicable

exemptions to any such Tax or fee, and (c) each pay any such Tax or fee which becomes payable by it on or before the due date therefor.

5.11 Investigation by Parent and Merger Sub; No Other Representations or Warranties.

(a) Each of Parent and Merger Sub acknowledges and agrees that it has made its own inquiry and investigation into, and, based on the information provided by the Company, has formed an independent judgment concerning, the Company and its Subsidiaries and their businesses and operations, and Parent and Merger Sub have requested such documents and information from the Company as each such party considers material in determining whether to enter into this Agreement and to consummate the transactions contemplated in this Agreement. Each of Parent and Merger Sub acknowledges and agrees that it has had an opportunity to ask all questions of and receive answers from the Company with respect to any matter such party considers material in determining whether to enter into this Agreement and to consummate the transactions contemplated in this Agreement.

(b) Each of Parent and Merger Sub agrees that, except for the representations and warranties made by the Company that are expressly set forth in Section 3.1 of this Agreement (as modified by the Company Disclosure Letter or as disclosed in the Company SEC Documents) and in any certificate provided pursuant to Section 6.2(c), neither the Company nor any other Person has made and shall not be deemed to have made any representation or warranty of any kind. Without limiting the generality of the foregoing, each of Parent and Merger Sub agrees that neither the Company, any holder of the Company’s securities nor any of their respective Affiliates or Representatives, makes or has made any representation or warranty to Parent, Merger Sub or any of their representatives or Affiliates with respect to:

(i) any projections, forecasts or other estimates, plans or budgets of future revenues, expenses or expenditures, future results of operations (or any component thereof), future cash flows (or any component thereof) or future financial condition (or any component thereof) of the Company or any of its Subsidiaries or the future business, operations or affairs of the Company or any of its Subsidiaries heretofore or hereafter delivered to or made available to Parent, Merger Sub or their respective representatives or Affiliates; or

(ii) any other information, statement or documents heretofore or hereafter delivered to or made available to Parent, Merger Sub or their respective representatives or Affiliates, except to the extent and as expressly covered by a representation and warranty made by the Company and contained in Section 3.1 of this Agreement.

5.12 Financing.

(a) Parent shall use its reasonable best efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary, proper or advisable to arrange and consummate the financing necessary to consummate the Transactions (the “Debt Financing”) on the terms and conditions described in the Debt Commitment Letter, including

using reasonable best efforts to (i) satisfy on a timely basis all terms, covenants and conditions set forth in the Debt Commitment Letter; (ii) enter into definitive agreements with respect thereto on the terms and conditions contemplated by the Debt Commitment Letter; (iii) enforce its rights under the Debt Commitment Letter; and (iv) consummate the Debt Financing at or prior to the Effective Time. Parent will furnish correct and complete copies of all such definitive agreements to the Company promptly upon their execution.

(b) Parent shall keep the Company informed with respect to all material activity concerning the status of the Debt Financing contemplated by the Debt Commitment Letter and shall give the Company prompt notice of any material adverse change with respect to such Debt Financing. Without limiting the foregoing, Parent agrees to notify the Company promptly, and in any event within two Business Days, if at any time (i) any Debt Commitment Letter shall expire or be terminated for any reason, (ii) any financing source that is a party to any Debt Commitment Letter notifies Parent that such source no longer intends to provide financing to Parent on the terms set forth therein, or (iii) for any reason Parent no longer believes in good faith that it will be able to obtain all or any portion of the Financing contemplated by the Debt Commitment Letter on the terms described therein. Parent shall not, and shall not permit any of its Affiliates to, without the prior written consent of the Company, take or fail to take any action or enter into any transaction, including any merger, acquisition, joint venture, disposition, lease, contract or debt or equity financing, that could reasonably be expected to breach or make untrue any representation or warranty contained in the Commitment Letters or otherwise impair, delay or prevent consummation of the Financing contemplated by any of the Debt Commitment Letter. Parent shall not amend or alter, or agree to amend or alter, any Debt Commitment Letter in any manner that would prevent or materially impair or delay the consummation of Transactions without the prior written consent of the Company.

(c) If any portion of the Debt Financing becomes unavailable on the terms and conditions contemplated in the Debt Commitment Letter or any Debt Commitment Letter shall be terminated or modified in a manner materially adverse to Parent for any reason, Parent shall use its reasonable best efforts to arrange to obtain alternative financing from alternative sources in an amount sufficient to consummate the Transactions (“Alternate Financing”) and to obtain, and, if obtained, will provide the Company with a copy of, a new financing commitment that provides for at least the same amount of financing as such Debt Commitment Letter as originally issued and on terms and conditions (including termination rights and funding conditions) no less favorable to Parent or Merger Sub than those included in such Debt Commitment Letter (the “New Commitment Letter”). To the extent applicable, Parent shall use its reasonable best efforts to take, or cause to be taken, all things necessary, proper or advisable to arrange promptly and consummate the Alternate Financing on the terms and conditions described in any New Commitment Letter, including using reasonable best efforts to (i) satisfy on a timely basis all terms, covenants and conditions set forth in the New Commitment Letter; (ii) enter into definitive agreements with respect thereto on the terms and conditions contemplated by the New Commitment Letter; (iii) enforce its rights under the New Commitment Letter; and (iv) consummate the Alternate Financing at or prior to the Closing.

5.13 Reasonable Best Efforts; Notification.

(a) Except to the extent that the parties’ obligations are specifically set forth elsewhere in this ARTICLE V, upon the terms and subject to the conditions set forth in this Agreement (including Section 4.2), each of the parties shall use reasonable best efforts to take, or cause to be taken, all actions, and to do, or cause to be done, and to assist and cooperate with the other parties in doing, all things necessary, proper or advisable to consummate and make effective, in the most expeditious manner practicable, the Merger and the other Transactions.

(vi) assist Parent in procuring accountants’ comfort letters and consents, payoff letters, lien releases, legal opinions, surveys and title insurance as reasonably requested by Parent;

Parent shall indemnify and hold harmless the Company and its Subsidiaries and their respective officers, directors and other representatives for and against any and all losses or damages suffered or incurred by them in connection with the arrangement of the Debt Financing and any information utilized in connection therewith except with respect to information supplied by the Company specifically for inclusion or incorporation by reference therein.

(e) The Company shall give prompt notice to Parent, and Parent or Merger Sub shall give prompt notice to the Company, upon becoming aware (i) that any representation or warranty made by it in this Agreement has become untrue or inaccurate in any material respect (ii) of any condition, event or circumstance that will result in any of the conditions in Section 6.2(a) or 6.3(a) not being met, or (iii) of the failure by it to comply with or satisfy in any material respect any covenant, condition or agreement to be complied with or satisfied by it under this Agreement; provided, however, that no such notification shall affect the representations, warranties, covenants or agreements of the parties or the conditions to the obligations of the parties under this Agreement.

(f) Parent and its Affiliates shall not (i) amend or otherwise change any of its or Merger Sub’s organization documents, or (ii) enter into any transaction or take any action, that in the case of clause (i) or (ii) could reasonably be expected to have a Parent Material Adverse Effect.

derivative securities) pursuant to the transactions contemplated by this Agreement by any officer or director of the Company who is subject to Section 16 of the Exchange Act to be exempt under Rule 16b-3 promulgated under the Exchanges Act in accordance with the procedures set forth in such Rule 16b-3 and the Skadden, Arps, Slate, Meagher & Flom LLP SEC No-Action Letter (January 12, 1999).

7.3 Expenses and Other Payments.

(a) Except as otherwise provided in this Agreement, each party hereto shall pay its own expenses incident to preparing for, entering into and carrying out this Agreement and the consummation of the Transactions, whether or not the Merger shall be consummated.

Accordingly, any rule of law or any legal decision that would require interpretation of any ambiguities in this Agreement against any party that drafted it is of no application and is hereby expressly waived.

(b) The inclusion of any information in the Company Disclosure Letter or Parent Disclosure Letter shall not be deemed an admission or acknowledgment, in and of itself and solely by virtue of the inclusion of such information in the Company Disclosure Letter or Parent Disclosure Letter, as applicable, that such information is required to be listed in the Company Disclosure Letter or Parent Disclosure Letter, as applicable, or that such items are material to the Company and its Subsidiaries taken as a whole, Parent or Merger Sub, as the case may be. The headings, if any, of the individual sections of each of the Parent Disclosure Letter and Company Disclosure Letter are inserted for convenience only and shall not be deemed to constitute a part thereof or a part of this Agreement. The Company Disclosure Letter and Parent Disclosure Letter are arranged in sections corresponding to those contained in Section 3.1 and Section 3.2 merely for convenience, and the disclosure of (i) an item in one section of the Company Disclosure Letter or Parent Disclosure Letter as an exception to a particular representation or warranty and (ii) disclosures made in the Company SEC Documents shall in each case be deemed adequately disclosed as an exception with respect to all other representations or warranties to the extent that the relevance of such item to such representations or warranties is readily apparent on its face from such item, notwithstanding the presence or absence of an appropriate section of the Company Disclosure Letter or Parent Disclosure Letter with respect to such other representations or warranties or an appropriate cross reference thereto.

(c) The specification of any dollar amount in the representations and warranties or otherwise in this Agreement or in the Company Disclosure Letter or Parent Disclosure Letter is not intended and shall not be deemed to be an admission or acknowledgment of the materiality of such amounts or items, nor shall the same be used in any dispute or controversy between the parties to determine whether any obligation, item or matter (whether or not described herein or included in any schedule) is or is not material for purposes of this Agreement.

(d) All references in this Agreement to Exhibits, Schedules, Articles, Sections, subsections and other subdivisions refer to the corresponding Exhibits, Schedules, Articles, Sections, subsections and other subdivisions of this Agreement unless expressly provided otherwise.

The words “this Section,” “this subsection” and words of similar import, refer only to the Sections or subsections hereof in which such words occur.
