ARTICLE II
THE OFFER

     2.1 The Offer.

          (a) Commencement. As promptly as reasonably practicable after the date hereof (and in any event no more than ten Business Days thereafter), Merger Sub shall (and Parent shall cause Merger Sub to) commence (within the meaning of Rule 14d-2 under the Exchange Act) the Offer at the Offer Price, subject to the terms of Section 2.1(d).

          (b) Conditions of the Offer. The obligation of Merger Sub to accept for payment and pay for any shares of Company Common Stock tendered in the Offer shall be subject only to (i) the condition (the “Minimum Condition”) that, prior to the expiration of the Offer, there be validly tendered and not withdrawn in accordance with the terms of the Offer a number of shares of Company Common Stock that, together with the shares of Company Common Stock then owned by Parent and Merger Sub (if any), represents at least a majority of all then outstanding shares of Company Common Stock on a fully diluted basis, assuming the issuance of all shares of Company Common Stock that may be issued upon the vesting, conversion or exercise of all outstanding options, warrants, convertible or exchangeable securities and similar rights (other than the Top-Up Option); and (ii) the other conditions set forth in Annex A (together with the Minimum Condition, the “Offer Conditions”).

          (c) Waiver of Offer Conditions. Parent and Merger Sub expressly reserve the right to waive any of the Offer Conditions and to make any change in the terms or conditions of the Offer; provided, however, that neither Parent nor Merger Sub may (i) waive or modify the Minimum Condition or the condition set forth in clause (A)(i) of Annex A, or (ii) change the form of consideration to be paid in the Offer, (iii) decrease the Offer Price or the number of shares of Company Common Stock sought in the Offer, (iv) extend the Offer, other than in a manner contemplated by the provisions of Section 2.1(e), (v) amend or modify the other Offer Conditions in any manner adverse to the holders of Company Common Stock, or impose additional or different conditions to the Offer other than those set forth in Section 2.1(b) or Annex A, or (vi) reduce the initial time period during which the Offer shall remain open.

          (d) Adjustments to the Offer Price. The Offer Price shall be adjusted appropriately to reflect the effect of any stock split, reverse stock split, stock dividend (including any dividend or distribution of securities convertible into shares of Company Common Stock), reclassification, combination, exchange of shares or other like change with respect to shares of Company Common Stock occurring on or after the date hereof and prior to Merger Sub’s consummation of the Offer. The Offer Price may be increased by Parent or Merger Sub at any time without the consent of the Company.

          (e) Expiration and Extension of the Offer. The Offer shall initially be scheduled to expire at midnight, New York City time, on the date that is the later of (1) thirty Business Days after the date of this Agreement and (2) twenty Business Days (calculated in accordance with Rule 14d-1(g)(3) under the Exchange Act) after the date the Offer is first commenced within the meaning of Rule 14d-2 under the Exchange Act (the initial expiration date, or any subsequent date to which the Offer is extended pursuant to this Agreement, the “Expiration Date”). Notwithstanding the first sentence of this Section 2.1(e), (i) Merger Sub shall extend the Offer for any period required by any Law or Order, or any rule or regulation of the NASDAQ that is applicable to the Offer, (ii) if all of the Offer Conditions are not satisfied or waived (if permitted hereunder) as of any then scheduled Expiration Date of the Offer, Merger Sub may and, if requested in writing by the Company, Merger Sub shall, extend the Offer for successive extension periods of up to ten Business Days each (or such longer period as the parties may agree) until the Offer Conditions are satisfied or waived, and (iii) if upon the acceptance of, and payment for, all shares of Company Common Stock validly tendered and not withdrawn pursuant to the Offer as of any then scheduled Expiration Date, Parent and Merger Sub collectively would not beneficially own at least 90% of the shares of Company Common Stock, then Merger Sub may, without the consent of the Company, extend the Offer for successive extension periods of up to ten Business Days each (or such longer period as the parties may agree); provided, however, that the foregoing clauses (i), (ii) or (iii) of this Section 2.1(e) shall not (x) be deemed to impair, limit or otherwise restrict in any manner the right of the parties to terminate this Agreement pursuant to Article X, (y) require the extension of the Offer if such extension is prohibited by any Law or Order or any rule or regulation of the SEC or the NASDAQ, in any such case which is applicable to the Offer or (z) require Merger Sub to extend the Offer beyond the Outside Date or at any time Merger Sub or Parent is then permitted to terminate this Agreement pursuant to Article X. Neither Parent nor Merger Sub shall terminate or withdraw the Offer prior to the then scheduled expiration of the Offer unless this Agreement is terminated in accordance with Article X, in which case Merger Sub shall (and Parent shall cause Merger Sub to) irrevocably and unconditionally terminate the Offer promptly (but in no event more than one Business Day) after such termination of this Agreement. Notwithstanding anything to the contrary in this Section 2.1(e), if this Agreement is terminated pursuant to Section 10.1, then Merger Sub shall promptly (and, in any event, within two Business Days of such termination), irrevocably and unconditionally terminate the Offer. If the Offer is terminated or withdrawn by Merger Sub, or this Agreement is terminated in accordance with Section 10.1, Merger Sub shall promptly return, and shall cause any depository acting on behalf of Merger Sub to return, all tendered shares of Company Common Stock to the registered holders thereof to the extent required by the terms of the Offer.

          (f) Payment for Company Common Stock. On the terms and subject to conditions set forth in this Agreement and the Offer, Merger Sub shall (and Parent shall cause Merger Sub to) accept for payment and pay for all shares of Company Common Stock that are validly tendered and not withdrawn pursuant to the Offer promptly (within the meaning of Section 14e-1(c) under the Exchange Act) after the Expiration Date of the Offer. Without limiting the generality of the foregoing, Parent shall provide or cause to be provided to Merger Sub on a timely basis the funds necessary to pay for any shares of Company Common Stock that Merger Sub becomes obligated to purchase pursuant to the Offer.

          (g) Subsequent Offering Periods. If upon the acceptance of and payment for all shares of Company Common Stock validly tendered and not withdrawn pursuant to the Offer, Parent and Merger Sub do not collectively own at least 90% of the outstanding shares of Company Common Stock (without giving effect to the exercise of the Top-Up Option), Merger Sub may (but shall not be required to), and the offer to purchase shall reserve the right to, provide for one or more “subsequent offering periods” (within the meaning of Rule 14d-11 under the Exchange Act) immediately following the Expiration Date of the Offer. Subject to the terms and conditions of this Agreement and the Offer, Merger Sub shall (and Parent shall cause Merger Sub to) accept for payment and pay for all shares of Company Common Stock that are validly tendered during any such “subsequent offering period” promptly (within the meaning of Rule 14e-1(c) under the Exchange Act) after any such shares of Company Common Stock are validly tendered during such “subsequent offering period.” Without limiting the generality of the foregoing, Parent shall provide or cause to be provided to Merger Sub on a timely basis the funds necessary to pay for any shares of Company Common Stock that Merger Sub becomes obligated to purchase during such “subsequent offering period.”

          (h) Schedule TO; Offer Documents. On the date the Offer is commenced (within the meaning of Rule 14d-2 under the Exchange Act), Parent and Merger Sub shall (i) file with the SEC a Tender Offer Statement on Schedule TO (together with all amendments and supplements thereto, and including all exhibits thereto, the “Schedule TO”) with respect to the Offer, which Schedule TO shall contain as an exhibit the offer to purchase and forms of the letter of transmittal and summary advertisement, if any, and other customary ancillary documents, in each case, in respect of the Offer (together with any supplements or amendments thereto, the “Offer Documents”); and (ii) cause the Offer Documents to be disseminated to all Company Stockholders as and to the extent required by the Exchange Act.

     Subject to the provisions of Section 6.2(f), the Schedule TO and the Offer Documents may include (and the Company hereby consents to such inclusion) a description of the determinations, approvals and recommendations of the Company Board set forth in Section 2.2(a) that relate to the Offer (such determinations, approvals and recommendations are referred to collectively as the “Company Board Recommendation”). The Company agrees to promptly furnish to Parent and Merger Sub all information concerning the Company and its Subsidiaries that is required by applicable Law to be included in the Schedule TO or the Offer Documents. Parent, Merger Sub and the Company shall cooperate in good faith to determine and include the information regarding the Company that is necessary, reasonably appropriate, or otherwise reasonably requested by Parent for inclusion in the Schedule TO and the Offer Documents in order to satisfy applicable Laws. Each of Parent, Merger Sub and the Company agrees to promptly correct any information provided by it or on its behalf for use in the Schedule TO or the Offer Documents if and to the extent that such information shall have become false or misleading in any material respect and to supplement the information contained in the Schedule TO and the Offer Documents to include any information that shall become necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading. Parent and Merger Sub agree to take all steps necessary to cause the Schedule TO and the Offer Documents, as so corrected or supplemented, to be filed with the SEC and the other Offer Documents, as so corrected, to be disseminated to the holders of Company Common Stock, in each case as and to the extent required by applicable Laws or the NASDAQ. Unless

the Company Board has effected a Company Adverse Recommendation Change, Parent and Merger Sub shall provide the Company and its counsel a reasonable opportunity to review and comment on the Schedule TO and the Offer Documents prior to the filing thereof with the SEC (it being understood that the Company and its counsel shall provide any comments thereon as soon as reasonably practicable). Parent and Merger Sub shall provide in writing to the Company and its counsel any and all comments or other communications, whether written or oral, that Parent, Merger Sub or their counsel may receive from the SEC or its staff with respect to the Schedule TO and the Offer Documents promptly after such receipt, and unless the Company Board has effected a Company Adverse Recommendation Change, Parent and Merger Sub shall provide the Company and its counsel a reasonable opportunity to participate in the formulation of any response to any such comments of the SEC or its staff (including a reasonable opportunity to review and comment on any such response).

          (i) Withholding. Merger Sub shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to the Offer to any of the Company’s stockholders such amounts as Merger Sub is required to deduct and withhold with respect to the making of such payment under the Code or any other applicable Tax Law. To the extent that amounts are so withheld and paid over to the appropriate Taxing Authority by Merger Sub, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to such Company stockholder in respect of which such deduction and withholding was made by Merger Sub.

          (j) Notices of Guaranteed Delivery. For purposes of this Agreement, including the exercise of the Top-Up Option, and the Offer, unless otherwise mutually agreed to by the Company and Merger Sub, any shares of Company Common Stock subject to notices of guaranteed delivery shall be deemed not to be validly tendered into the Offer unless and until the shares of Company Common Stock underlying such notices of guaranteed delivery are delivered to or on behalf of Merger Sub.

     2.2 Company Actions.

          (a) Company Approvals. The Company hereby approves and consents to the Offer and represents and warrants to Parent and Merger Sub that, at a meeting duly called and held prior to the date hereof, the Company Board has unanimously adopted resolutions (which as of the date hereof have not been rescinded or modified in any way) pursuant to which the Company Board:

               (i) determined that the terms of this Agreement and the transactions contemplated hereby, including the Offer and the Merger, are advisable and fair to and in the best interests of the Company and the holders of Company Common Stock;

               (ii) approved the execution, delivery and performance of this Agreement and the transactions contemplated hereby, including the Offer, the Merger and the Tender and Voting Agreements, which approval, to the extent applicable, constituted approval under the provisions of Section 203 of the DGCL as a result of which this Agreement, the Offer, the Merger, Parent and Merger Sub and the Tender and Voting Agreements are not and will not

be subject to the provisions of, or any restrictions under, the provisions of Section 203 of the DGCL;

               (iii) recommended that the holders of Company Common Stock accept the Offer, tender their shares of Company Common Stock pursuant to the Offer and, if required by applicable Law, approve and adopt this Agreement and the Merger; and

               (iv) elected that this Agreement and the transactions contemplated hereby, including the Offer, the Merger and the Tender and Voting Agreements, to the extent of the Company Board’s power and authority and to the extent permitted by Law, not be subject to any “moratorium,” “control share acquisition,” “business combination,” “fair price” or other form of anti-takeover Laws of any jurisdiction that may purport to be applicable to this Agreement, the Tender and Voting Agreements or the transactions contemplated herein.

     The Company hereby consents to the inclusion of the foregoing determinations, approvals and recommendations in the Offer Documents subject to the Company’s rights to withdraw, amend or modify the recommendations in accordance with Section 6.2(f).

          (b) Schedule 14D-9. The Company shall (i) file with the SEC, on the date on which Parent and Merger Sub file the Schedule TO with the SEC, a Solicitation/Recommendation Statement on Schedule 14D-9 (together with all amendments and supplements thereto, and including all exhibits thereto, the “Schedule 14D-9”) with respect to the Offer which will comply in all material respects with the provisions of applicable Law and (ii) cause the Schedule 14D-9 to be disseminated to all holders of Company Common Stock promptly after the commencement of the Offer (within the meaning of Rule 14d-2 under the Exchange Act) to the extent required by applicable Law. The Company agrees to cooperate with Parent and Merger Sub in mailing or otherwise disseminating the Schedule 14D-9 with the Offer Documents to the holders of Company Common Stock. Subject to the provisions of Section 6.2, the Schedule 14D-9 shall include a description of the Company Board Recommendation. The Company shall also include in the Schedule 14D-9 the Fairness Opinion. Each of Parent and Merger Sub agree to promptly furnish to the Company all information concerning Parent and Merger Sub that may be required by applicable Laws to be included in the Schedule 14D-9. Parent, Merger Sub and the Company agree to cooperate in good faith to determine the information regarding the Company that is necessary or reasonably appropriate to include in the Schedule 14D-9 in order to satisfy applicable Laws. Each of the Company, Parent and Merger Sub shall promptly correct any information provided by it or on its behalf for use in the Schedule 14D-9 if and to the extent that such information shall have become false or misleading in any material respect and to supplement the information contained in the Schedule 14D-9 to include any information that shall become necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading. The Company shall take all steps necessary to cause the Schedule 14D-9, as so corrected or supplemented, to be filed with the SEC and disseminated to the holders of Company Common Stock, in each case as and to the extent required by applicable Laws. The Company shall provide Parent, Merger Sub and their counsel a reasonable opportunity to review and comment on the Schedule 14D-9 prior to the filing thereof with the SEC, and the Company shall give reasonable consideration to any comments made by Parent, Merger Sub and their counsel (it being understood that Parent,

Merger Sub and their counsel shall provide any comments thereon as soon as reasonably practicable). The Company shall provide in writing to Parent, Merger Sub and their counsel any comments or other communications, whether written or oral, the Company or its counsel may receive from the SEC or its staff with respect to the Schedule 14D-9 promptly after such receipt, and the Company shall provide Parent, Merger Sub and their counsel a reasonable opportunity to participate in the formulation of any response to any such comments of the SEC or its staff (including a reasonable opportunity to review and comment on any such response, to which the Company shall give reasonable consideration to any comments made by Parent, Merger Sub and their counsel) and to participate in any discussions with the SEC or its staff regarding any such comments.

          (c) Stockholder Information. In connection with the Offer, promptly following the date of this Agreement the Company shall furnish or cause to be furnished to Parent mailing labels containing the names and addresses of all of its stockholders of record, a non-objecting beneficial owners list and security position listings of shares of Company Common Stock held in stock depositories, each as of a recent date, and shall promptly furnish Parent with such additional information, including updated lists of stockholders and beneficial owners, mailing labels, security position listings and computer files, and such other information and assistance as Parent or its agents may reasonably request for the purpose of communicating the Offer to the record holders and beneficial owners of Company Common Stock. In addition, in connection with the Offer the Company shall, and shall use its reasonable best efforts to cause third parties to, cooperate with Parent and Merger Sub to disseminate the Offer Documents to the holders of Company Common Stock held in or subject to any Company Stock Plan and to permit such holders of Company Common Stock to tender their shares of Company Common Stock into the Offer. Subject to the requirements of applicable Law, and except for such steps as are necessary to disseminate the Offer Documents and any other documents necessary to consummate the Offer and the Merger, Parent and Merger Sub and their agents (i) shall hold in confidence the information contained in any such labels, listings and files and will use such information only in connection with the Offer and the Merger and (ii) following the termination of this Agreement in accordance with Article X, shall promptly, at the election of Parent, deliver to the Company or destroy, and will use their reasonable best efforts to cause their agents to deliver to the Company or destroy, all copies and any extract or summaries of such information then in their possession or control and promptly certify to the Company in writing that all such material has been returned or destroyed.

     2.3 Company Board of Directors and Committees; Section 14(f) of Exchange Act.

          (a) Composition of Company Board and Board Committees. Effective upon the Acceptance Time (provided that the Minimum Condition has been satisfied), the use of which term herein shall not, unless the context otherwise requires, depend upon whether Parent shall exercise its rights under this Section 2.3(a)) and from time to time thereafter, Parent shall be entitled to elect or designate up to such number of directors on the Company Board equal to the product (rounded up to the next whole number) obtained by multiplying (x) the number of directors on the Company Board (giving effect to any increase in the number of directors pursuant to this Section 2.3) and (y) a fraction, the numerator of which is the number of shares of Company Common Stock beneficially owned by Parent and Merger Sub (giving effect to the

shares of Company Common Stock accepted for payment pursuant to the Offer), and the denominator of which is the total number of then outstanding shares of Company Common Stock. Following a request by Parent, the Company shall, to the extent permitted by applicable Laws and the certificate of incorporation of the Company, take at the Company’s expense all action necessary to cause the individuals so designated by Parent to be elected or appointed to the Company Board, including (at the election of Parent) by increasing the size of the Company Board or by seeking and accepting or otherwise securing the resignations of such number of then incumbent directors as is necessary to enable the individuals so designated by Parent to be elected or appointed to the Company Board. From time to time after the Acceptance Time, at the request of Parent, the Company shall, to the extent permitted by applicable Laws and the certificate of incorporation of the Company, take all action necessary to cause the individuals so designated by Parent to constitute substantially the same percentage (rounding up where appropriate) as is on the Company Board on (i) each committee of the Company Board, (ii) each board of directors of each Subsidiary of the Company and (iii) each committee of each such board of directors of each Subsidiary of the Company, in each case to the extent permitted by applicable Law and the continued listing requirements of NASDAQ. The Company shall promptly amend, or cause to be amended, its bylaws, if necessary, to comply with the obligations of the Company pursuant to this Section 2.3. Notwithstanding the foregoing, from the Acceptance Time until the Effective Time, the Company shall use its reasonable best efforts to cause the Company Board to always have at least three directors who are directors on the date hereof, who are not employed by the Company and who are not Affiliates or employees of Parent or any of its Subsidiaries, and who are independent directors for purposes of the continued listing requirements of NASDAQ and Rule 10A-3 of the Exchange Act, and also eligible to serve on the Company’s audit committee under the Exchange Act and the continued listing standards of NASDAQ and at least one of whom shall be an “audit committee financial expert” as defined in Item 407(d)(5)(ii) of Regulation S-K and the instructions thereto (the “Continuing Directors”); provided that, if the number of Continuing Directors shall be reduced below three for any reason whatsoever, the remaining Continuing Director(s) shall be entitled to designate any other Person(s) who shall not be an Affiliate or employee of Parent or any of its Subsidiaries to fill such vacancies and such Person(s) shall be deemed to be a Continuing Director(s) for purposes of this Agreement; provided further, that the remaining Continuing Director shall fill such vacancies as soon as practicable, but in any event within ten Business Days, and further provided that if no such Continuing Director(s) are appointed in such time period, Parent shall designate such Continuing Director(s); provided further, that if no Continuing Director then remains, the other directors shall designate three Persons who shall not be Affiliates, consultants, representatives or employees of Parent or any of its Subsidiaries to fill such vacancies and such Persons shall be deemed to be Continuing Directors for purposes of this Agreement.

          (b) Section 14(f) of the Exchange Act. The Company shall promptly take all action required pursuant to this Section 2.3 and Section 14(f) of the Exchange Act and Rule 14f-1 thereunder in order to fulfill its obligations under this Section 2.3, shall include in the Schedule 14D-9 such information with respect to the Company and its directors and officers, as well as Parent’s designees to the Company Board, as is required under Section 14(f) of the Exchange Act and Rule 14f-1 thereunder. Parent shall provide to the Company in writing, and be solely

responsible for, any information with respect to itself and its designees to the Company Board required by such Section 14(f) of the Exchange Act and Rule 14f-1 thereunder.

          (c) Required Approvals of Continuing Directors. Following the election or appointment of Parent’s designees to the Company Board pursuant to Section 2.3(a) and until the Effective Time, the approval of a majority of the Continuing Directors shall be required to authorize (and such authorization shall constitute the authorization of the Company Board and no other action on the part of the Company, including any action by any other director of the Company, shall be required to authorize) (i) any amendment or termination of this Agreement on behalf of the Company, (ii) any amendment of this Agreement requiring action by the Company Board, (iii) any extension of time for performance of any obligation or action hereunder by Parent or Merger Sub, (iv) any exercise, enforcement or waiver of compliance with any of the agreements or conditions contained herein for the benefit of the Company, (v) any other action to be taken or not to be taken on behalf of the Company in connection with this Agreement; and (vi) except as provided herein, to amend the governing documents of the Company. The Continuing Directors shall have the authority to retain such counsel (which may include current counsel to the Company) and other advisors at the expense of the Company, and shall have the authority, after the Acceptance Time, to institute any action on behalf of the Company to enforce the performance of this Agreement in accordance with its terms.

          (d) Following the Acceptance Time, the Company shall, upon Parent’s request, take all action necessary to elect to be treated as a “controlled company” as defined by the rules and regulations of the NASDAQ and make all necessary filings and disclosures associated with such status.

     2.4 Top-Up Option.

          (a) The Company hereby grants to Merger Sub an irrevocable option (the “Top-Up Option”) to purchase, at a price per share equal to the Offer Price, that number of authorized and unissued shares of Company Common Stock (the “Top-Up Option Shares”) equal to the lowest number of shares of Company Common Stock that, when added to the number of shares of Company Common Stock owned by Parent and/or Merger Sub at the time of such exercise, shall constitute 100 shares of Company Common Stock more than the number of shares of Company Common Stock necessary for Merger Sub to be merged into the Company without a vote or consent of the Company’s stockholders in accordance with Section 253 of the DGCL; provided, however, that the Top-Up Option shall not be exercisable (i) unless immediately after such exercise and the issuance of shares of Company Common Stock pursuant thereto, Merger Sub would own more than the number of shares of Company Common Stock necessary for Merger Sub to be merged into the Company without a vote or consent of the Company’s stockholders in accordance with Section 253 of the DGCL (assuming the issuance of the Top-Up Option Shares) and (ii) for a number of shares of Company Common Stock in excess of the number of then authorized and unissued shares together with shares of Company Common Stock held as treasury shares. For the avoidance of doubt, nothing herein shall be construed or is intended to obligate Merger Sub to exercise the Top-Up Option.

          (b) Merger Sub may exercise the Top-Up Option, in whole but not in part, at any one time after the Acceptance Time and prior to the earlier to occur of (i) the Effective Time

and (ii) the termination of this Agreement pursuant to Article X. The aggregate purchase price payable for the Top-Up Option Shares being purchased by Merger Sub pursuant to the Top-Up Option may be paid by Merger Sub, at its election, either (A) entirely in cash or (B) by paying in cash in an amount equal to the aggregate par value of the purchased Top-Up Option Shares and executing and delivering to the Company an unsecured promissory note issued by Merger Sub having a principal amount equal to the remainder of such purchase price. The promissory note shall be full recourse against Parent and Merger Sub, shall bear interest at a rate of 5% per annum, shall mature on the first anniversary of the date of execution of the promissory note, and may be prepaid in whole or in part at any time without premium or penalty, and shall have no other material terms.

          (c) In the event Merger Sub wishes to exercise the Top-Up Option, Merger Sub shall deliver to the Company a notice (the “Top-Up Notice”) setting forth (i) the number of shares of Company Common Stock owned by Parent and its Subsidiaries, (ii) the number of Top-Up Option Shares that Merger Sub intends to purchase pursuant to the Top-Up Option, (iii) the manner in which Merger Sub intends to pay the applicable purchase price and (iv) the place and time at which the closing of the purchase of such Top-Up Option Shares by Merger Sub is to take place. At the closing of the purchase of the Top-Up Option Shares, Parent and Merger Sub shall cause to be delivered to the Company the consideration required to be delivered in exchange for the Top-Up Option Shares being purchased pursuant to the Top-Up Option, and the Company shall cause to be issued to Merger Sub a certificate representing such Top-Up Option Shares and upon request of Parent, the Company will use its reasonable best efforts to cause its transfer agent to certify in writing the number of shares of Company Common Stock outstanding immediately prior to issuance of the Top-Up Option Shares. The parties hereto agree to use their reasonable best efforts to cause the closing of the purchase of such Top-Up Option Shares to occur on the same day that the Top-Up Notice is deemed received by the Company pursuant to Section 11.2, and if not so consummated on such day, as promptly thereafter as possible. The parties further agree to use their reasonable best efforts to cause the Merger to be consummated in accordance with Section 253 of the DGCL and as contemplated by Section 8.3(e) as close in time as possible to (including, to the extent possible, on the same day as) the issuance of the Top-Up Option Shares.

          (d) Parent and Merger Sub understand that the shares of Company Common Stock which Merger Sub may acquire upon exercise of the Top-Up Option will not be registered under the Securities Act and will be issued in reliance upon an exemption thereunder for transactions not involving a public offering. Parent and Merger Sub represent and warrant to the Company that Merger Sub is, or will be upon the purchase of the Top-Up Option Shares, an “accredited investor,” as defined in Rule 501 of Regulation D under the Securities Act. Merger Sub agrees that the Top-Up Option and the Top-Up Option Shares to be acquired upon exercise of the Top-Up Option are being and will be acquired by Merger Sub for the purpose of investment and not with a view to or for resale in connection with any distribution thereof within the meaning of the Securities Act. Any certificates evidencing Top-Up Option Shares shall include any legends required by applicable securities Laws.

          (e) No Effect on Appraisal Rights. Notwithstanding anything to the contrary contained herein, to the fullest extent permitted by applicable Law, each of the parties hereto

agrees and acknowledges that in any appraisal proceeding under Section 262 of the DGCL with respect to the Dissenting Company Shares, the Surviving Corporation shall not assert that the Top-Up Option, the Top-Up Option Shares or any cash or the promissory note delivered to the Company in payment for such Top-Up Option Shares should be considered in connection with the determination of the fair value of the Dissenting Company Shares in accordance with Section 262 of the DGCL.

          (f) Assignment of Top-Up Option. Without the prior written consent of the Company, the right to exercise the Top-Up Option granted pursuant to this Agreement shall not be assigned by Merger Sub other than to Parent or a direct or indirect wholly owned Subsidiary of Parent, including by operation of Law or otherwise, and any attempted assignment in violation of this Section 2.4(f) shall be null and void.

     3.3 The Closing. The consummation of the Merger shall take place at a closing (the “Closing”) to occur at the offices of Vinson & Elkins LLP, located at 1001 Fannin, Suite 2500, Houston, Texas 77002, on a date and at a time to be agreed upon by Parent and the Company, which date shall be no later than the third Business Day after the day on which the last to be satisfied or waived of the conditions set forth in Article IX (other than those conditions that by their terms are to be satisfied at the Closing) shall be satisfied or waived in accordance with this Agreement. The date on which the Closing shall actually occur pursuant hereto is referred to herein as the “Closing Date.”

     3.4 Effect of the Merger. At the Effective Time, the effect of the Merger shall be as provided in the applicable provisions of the DGCL.

     3.5 Certificate of Incorporation and Bylaws.

          (a) Certificate of Incorporation. At the Effective Time the certificate of incorporation of the Company shall be amended and restated to read in its entirety as set forth in Annex B, and such amended and restated certificate of incorporation shall be the certificate of incorporation of the Surviving Corporation until thereafter amended in accordance with the applicable provisions of the DGCL and such certificate of incorporation.

          (b) Bylaws. At the Effective Time the bylaws of Merger Sub, as in effect immediately prior to the Effective Time, shall be the bylaws of the Surviving Corporation until thereafter amended in accordance with the applicable provisions of the DGCL, the certificate of incorporation of the Surviving Corporation and such bylaws.

     3.6 Directors and Officers. The directors of Merger Sub immediately prior to the Effective Time shall be the only directors of the Surviving Corporation, each to hold office until his or her successor is duly elected or appointed and qualified or until his or her earlier death, resignation or removal. The officers of the Company immediately prior to the Effective Time shall be the officers of the Surviving Corporation at the Effective Time, each to hold office until the earlier of his or her resignation, removal or death and the due election and qualification of their successors.

     3.7 Effect on Capital Stock.

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

               (i) Capital Stock of Merger Sub. Each share of capital stock of Merger Sub that is outstanding immediately prior to the Effective Time shall be converted into one validly issued, fully paid and nonassessable share of common stock, par value $0.001 per share, of the Surviving Corporation. Each certificate evidencing ownership of such shares of capital stock of Merger Sub shall thereafter evidence ownership of shares of common stock of the Surviving Corporation.

               (ii) Company Common Stock. Each share of Company Common Stock that is outstanding immediately prior to the Effective Time other than (A) shares of Company Common Stock to be cancelled in accordance with Section 3.7(a)(iii), and (B) any Dissenting Company Shares (collectively, “Eligible Shares”) shall be canceled and automatically converted into the right to receive cash in an amount equal to the Offer Price (the “Merger Consideration”), without interest. Until the surrender of such Eligible Shares in the manner provided in Section 3.10, outstanding Certificates or book-entry representing Eligible Shares shall be deemed from and after the Effective Time, to evidence only the right to receive upon surrender the Merger Consideration, without interest. Each Dissenting Company Share, whether represented by a certificate or book-entry, shall thereafter represent only the right to receive the payments described in Section 3.8.

               (iii) Owned Company Common Stock and Dissenting Company Shares. Each share of Company Common Stock owned by Parent, Merger Sub or the Company, or by any direct or indirect wholly-owned Subsidiary of Parent, Merger Sub or the Company, in each case immediately prior to the Effective Time, and each Dissenting Company Share, shall be cancelled without any conversion thereof or consideration paid therefor, subject only to the rights of holders of Dissenting Company Shares as described in Section 3.8.

          (b) Adjustment to the Merger Consideration. The Merger Consideration shall be adjusted appropriately to reflect the effect of any stock split, reverse stock split, stock dividend (including any dividend or distribution of securities convertible into shares of Company Common Stock), reclassification, combination, exchange of shares or other like change with respect to shares of Company Common Stock occurring on or after the consummation of the Offer and prior to the Effective Time.

     3.8 Statutory Rights of Appraisal.

          (a) Notwithstanding anything to the contrary in this Agreement, any shares of Company Common Stock that are issued and outstanding immediately prior to the Effective Time and as to which the holders have properly demanded appraisal of such shares of Company Common Stock pursuant to Section 262 of the DGCL, and have not effectively withdrawn such demand (collectively, “Dissenting Company Shares”) shall not be converted into, or represent the right to receive, the Merger Consideration pursuant to Section 3.7, but rather such holders shall be entitled only to such rights and payments as are due in accordance with the provisions of Section 262 of the DGCL; provided, however, that all Dissenting Company Shares held by holders who shall have failed to perfect or who shall have otherwise waived, withdrawn or lost their rights to appraisal with respect to such Dissenting Company Shares under Section 262 of the DGCL shall no longer be considered to be Dissenting Company Shares, shall be deemed to have been an Eligible Share and to have been cancelled and converted, as of the Effective Time, into the right to receive the Merger Consideration, without interest.

          (b) The Company shall give Parent (i) prompt notice of any demands for appraisal received by the Company, withdrawals of such demands, and any other instruments served pursuant to the DGCL and received by the Company in respect of Dissenting Company Shares and (ii) the opportunity to direct all negotiations and proceedings with respect to demands for appraisal under the DGCL in respect of Dissenting Company Shares. The Company shall not, except with the prior written consent of Parent, voluntarily make any payment with respect to any demands for appraisal, or negotiate, settle or offer to settle any such demands or approve any withdrawal of any such demands.

     3.9 Company Options and Restricted Stock.

          (a) Parent shall not assume any Company Options in connection with the Merger or any other transactions contemplated by this Agreement. Upon the terms and subject to the conditions set forth in this Agreement, (i) prior to the Acceptance Time the Company shall cause the holders of each Company Option, whether vested or unvested, that remains outstanding immediately prior to the Acceptance Time to agree that each Company Option held by such holders shall be cancelled and terminated immediately prior to the Effective Time and (ii) in

consideration of such cancellation and termination, each holder of each such Company Option shall be paid by the Surviving Corporation at or promptly after the Effective Time, an amount in cash (without interest), if any, equal to the product obtained by multiplying (x) the aggregate number of shares of Company Common Stock that were issuable upon exercise of such Company Option immediately prior to the Effective Time, and (y) the Offer Price, less the per share exercise price of such Company Option (the “Option Consideration”) (it being understood and agreed that such exercise price shall not actually be paid to the Surviving Corporation by the holder of a Company Option).

          (b) Upon the terms and subject to the conditions set forth in this Agreement, any Company Restricted Stock Awards that vest as of or prior to the Acceptance Time shall be treated as shares of Company Common Stock for all purposes of this Agreement, including Section 2.1 and Section 3.7, and may be tendered to Merger Sub pursuant to the Offer. Each Company Restricted Stock Award under the Company Stock Plans that has not vested prior to the Effective Time, shall vest and all restrictions shall be removed from the shares of Company Common Stock subject thereto effective immediately prior to the Effective Time, so that all shares of Company Common Stock subject to such Company Restricted Stock Awards shall be treated as shares of Company Common Stock for all purposes of this Agreement, including Section 3.7 from and after the date of such vesting.

          (c) The Company and the Company Board shall take all actions they determine to be necessary or appropriate to effect the transactions contemplated by this Section 3.9 in a timely manner, including delivering all required notices and making any determinations and/or resolutions of the Company Board or a committee thereof. The Company shall take all actions it determines to be necessary or appropriate to ensure that neither Parent nor the Surviving Corporation will be required to deliver shares of Company Common Stock or other capital stock of the Company to any person pursuant to or in settlement of Company Options or Company Restricted Stock Awards after the Acceptance Time.

     3.10 Exchange of Certificates.

          (a) Exchange Fund. At or before the Effective Time, Parent shall deposit (or cause Merger Sub to deposit) with a bank or trust company reasonably acceptable to the Company to act as the payment agent for the Merger (the “Payment Agent”) an amount of cash sufficient in the aggregate to provide funds necessary to make payments to holders of Company Common Stock under Section 3.7(a)(ii) (such cash amount, excluding any interest or earnings thereon, being referred to herein as the “Exchange Fund”). Until disbursed in accordance with the terms and conditions of this Agreement, such funds shall be invested by the Payment Agent, as directed by Parent or the Surviving Corporation. Any interest and other income or net profits resulting from such investments shall be promptly paid to Parent. To the extent that there are any losses with respect to any investments of the Exchange Fund, or the Exchange Fund diminishes for any reason below the level required for the Payment Agent to promptly pay the consideration contemplated by Section 3.7(a)(ii), upon demand by the Payment Agent, Parent shall, or shall cause the Surviving Corporation to, promptly reimburse any such loss so as to ensure that the Exchange Fund is at all times maintained at a level sufficient for the Payment Agent to make such payments contemplated by Section 3.7(a)(ii). Upon Parent becoming aware that a holder of Dissenting Company Shares has effectively waived, withdrawn or lost such holder’s rights under Section 262 of the DGCL with respect to any Dissenting Company Shares, Parent shall make available or cause to be made available to the Payment Agent additional funds in an amount equal to the product of (x) the number of such Dissenting Company Shares and (y) the Merger Consideration.

          (b) Payment Procedures. Promptly following the Effective Time, Parent shall cause to be mailed to each holder of record as of the Effective Time of (i) a certificate or certificates (the “Certificates”) which immediately prior to the Effective Time represented shares of Company Common Stock or (ii) shares of Company Common Stock represented by book-entry (“each, a “Book-Entry Share”), in each case, whose shares were converted into the right to receive the Merger Consideration pursuant to Section 3.7 (x) a letter of transmittal in customary form (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon proper delivery of the Certificates to the Payment Agent or, in the case of Book-Entry Shares, upon adherence to the procedures set forth in the letter of transmittal), and (y) instructions for use in effecting the surrender of the Certificates and Book-Entry Shares in exchange for the Merger Consideration. Upon surrender of Certificates for cancellation to the Payment Agent, together with a letter of transmittal, duly completed and validly executed in accordance with the instructions thereto and such other documents as may be required pursuant to such instructions, or delivery to the Payment Agent of an “agent’s message” in respect of Book-Entry Shares (or such other evidence, if any, of transfer as the Paying Agent may reasonably request), the holder shall be entitled to receive in exchange therefor a check in the amount of U.S. dollars (after giving effect to any required withholdings pursuant to Section 3.10(d)) equal to the product of (x) the number of shares represented by such holder’s properly surrendered Certificates and/or Book-Entry Shares, as applicable, and (y) the per share Merger Consideration, and the Certificates and Book-Entry Shares so surrendered shall forthwith be canceled. The Payment Agent shall accept such Certificates and transferred Book-Entry Shares upon compliance with such reasonable terms and conditions as the Payment Agent may impose to effect an orderly exchange thereof in accordance with normal exchange practices. No interest

shall be paid or accrued on the Merger Consideration payable upon the surrender of such Certificates and Book-Entry Shares.

          (c) Transfers of Ownership; Payment Other than to Registered Owner. At the Effective Time the stock transfer books of the Company shall be closed and thereafter there shall be no further registration of transfers of shares of Company Common Stock that were issued and outstanding immediately prior to the Effective Time. If the Merger Consideration is to be paid in a name other than that in which the Certificates or Book-Entry Shares surrendered in exchange therefor are registered in the stock transfer books or ledger of the Company, it shall be a condition to payment that such Certificate or Book-Entry Shares is properly endorsed and otherwise in proper form for surrender and transfer and the Person requesting such payment has paid to Parent (or any agent designated by Parent) any transfer or other Taxes required by reason of the payment of the Merger Consideration to a Person other than the registered holder of such Certificate or Book-Entry Shares, or established to the satisfaction of Parent (or any agent designated by Parent) that such transfer or other Taxes have been paid or are otherwise not payable.

          (d) Withholding. Each of the Payment Agent, Parent, Merger Sub and the Surviving Corporation shall be entitled to deduct and withhold from any amounts payable pursuant to this Agreement to any Person pursuant to this Article III such amounts as may be required to be deducted or withheld therefrom or in respect thereof under U.S. federal, state or local or non-U.S. Tax Laws. To the extent that such amounts are so deducted or withheld, such amounts shall be treated for all purposes under this Agreement as having been paid to the Person to whom such amounts would otherwise have been paid.

          (e) No Liability. Notwithstanding anything to the contrary set forth in this Agreement, none of the Payment Agent, Parent, the Surviving Corporation or any other party hereto shall be liable to any Person for any amount from the Exchange Fund properly delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law.

          (f) Termination of Exchange. Any portion of the Exchange Fund that remains undistributed to the holders of the Certificates or Book-Entry Shares on the date that is 180 days after the Effective Time shall be delivered to Parent upon demand, and any holders of Company Common Stock that were issued and outstanding immediately prior to the Merger who have not theretofore surrendered their Certificates or Book-Entry Shares representing such shares of Company Common Stock for exchange pursuant to the provisions of this Section 3.10 shall thereafter look solely to Parent, as general creditors thereof, for any claim to the applicable Merger Consideration to which such holders may be entitled pursuant to the provisions of this Article III. Any amounts remaining unclaimed by holders of Company Common Stock that were issued and outstanding immediately prior to the Merger two years after the Effective Time (or such earlier date, immediately prior to such time when the amounts would otherwise escheat to or become property of any Governmental Authority) shall become, to the extent permitted by Law, the property of Parent free and clear of any claims or interest of any Person previously entitled thereto.

     3.11 No Further Ownership Rights in Company Common Stock. From and after the Effective Time, each holder of a Certificate or Book-Entry Shares theretofore representing any

shares of Company Common Stock shall cease to have any rights with respect thereto, except the right to receive the Merger Consideration payable therefor upon the surrender thereof in accordance with the provisions of Section 3.7. The Merger Consideration paid in accordance with the terms of this Article III shall be deemed to have been paid in full satisfaction of all rights pertaining to such shares of the Company Common Stock. If, after the Effective Time, Certificates or Book-Entry Shares are presented to the Surviving Corporation for any reason, they shall be canceled and exchanged as provided in this Article III.

     3.12 Lost, Stolen or Destroyed Certificates. If any Certificates shall have been lost, stolen or destroyed, the Payment Agent shall issue in exchange for such lost, stolen or destroyed Certificates, upon the making of an affidavit of that fact by the holder thereof, the Merger Consideration payable in respect thereof pursuant to Section 3.7; provided, however, that Parent may, in its discretion and as a condition precedent to the payment thereof, require the owner of such lost, stolen or destroyed Certificate to deliver a bond in such reasonable sum as Parent may direct as indemnity against any claim that may be made against Parent, the Surviving Corporation or the Payment Agent with respect to the Certificate alleged to have been lost, stolen or destroyed.

     3.13 Necessary Further Actions. If, at any time after the Effective Time, any further action is necessary or desirable to carry out the purposes of this Agreement and to vest the Surviving Corporation with full right, title and possession to all assets, property, rights, privileges, powers and franchises of the Company and Merger Sub, the directors and officers of the Company and Merger Sub shall take all such lawful and necessary action.

     6.2 No Solicitation.

          (a) The Company shall, and shall cause each of its Subsidiaries and its and their respective directors and officers and shall use reasonable best efforts to cause its employees, Affiliates, or any investment banker, attorney, agent or representative (collectively, “Representatives”) to (i) immediately cease and terminate any solicitation, knowing

encouragement, discussions, negotiations or other similar activities with any Persons other than Parent and its Representatives that may be ongoing with respect to, or that may reasonably be expected to lead to, an Acquisition Proposal and (ii) immediately revoke or withdraw access of any Person other than Parent and its Representatives to any data room (virtual or actual) containing any non-public information with respect to the Company or its Subsidiaries previously furnished with respect to any Acquisition Proposal and request such Person to promptly return or destroy, as elected by the Company, all confidential information concerning the Company and its Subsidiaries.

          (b) The Company shall not and shall cause each of its Subsidiaries and its and their respective directors and officers and shall use reasonable best efforts to cause its Representatives not to, directly or indirectly, (i) solicit, initiate, knowingly facilitate or knowingly encourage (including by way of furnishing information) any inquiries regarding, or the making or submission of any proposal or offer that constitutes, or would reasonably be expected to lead to, an Acquisition Proposal, (ii) conduct or engage in any discussions or negotiations with, disclose any information or data relating to the Company or any of its Subsidiaries to, or afford access to the business, properties, assets, books or records of the Company or any of its Subsidiaries to, or assist, knowingly facilitate or cooperate with any effort by, any Third Party with respect to or that is seeking to make or has made, any Acquisition Proposal, or (iii) enter into any agreement, including any agreement in principle, letter of intent, term sheet, acquisition agreement, merger agreement, option agreement, joint venture agreement, partnership agreement or other Contract relating to any Acquisition Proposal (each, a “Company Acquisition Agreement”) (other than an Acceptable Confidentiality Agreement in circumstances contemplated in Section 6.2(c)).

          (c) Notwithstanding anything to the contrary in Section 6.2(b), the Company either directly or through its Representatives may take the actions described in Section 6.2(b)(ii) with respect to a Third Party prior to but not after, the Acceptance Time, (i) if the Company receives after the date of this Agreement a bona fide, written Acquisition Proposal from such Third Party (and such Acquisition Proposal was not solicited, initiated, knowingly facilitated or knowingly encouraged (including by way of furnishing information) by the Company or any of its Subsidiaries, or any of its or their respective Representatives, and did not otherwise result from, or was not otherwise facilitated by, any breach of this Section 6.2) and (ii) if and to the extent that before taking any such actions, the Company Board determines in good faith, after consultation with its financial advisor and outside legal counsel, that (A) failure to take such action would be inconsistent with the directors’ fiduciary duties under applicable Law and (B) such Acquisition Proposal constitutes, or is reasonably expected to lead to, a Superior Proposal; provided that (1) the Company shall not deliver any information or data to such Third Party or afford such Third Party any access prior to entering into an Acceptable Confidentiality Agreement as to such Third Party and (2) the Company shall, as promptly as practicable (and in any event within 24 hours), provide to Parent a copy of such executed Acceptable Confidentiality Agreement. The Company agrees that it shall substantially concurrently with delivery to the Third Party provide to Parent any information concerning the Company or its Subsidiaries that is provided to any Third Party in connection with any Acquisition Proposal which information was not previously provided to Parent.

          (d) The Company shall, as promptly as practicable (and in any event within 24 hours after receipt), advise Parent orally and in writing of any request for information or any Acquisition Proposal received from any Person, or any inquiry, discussions or negotiations with respect to any Acquisition Proposal, and the material terms and conditions of such request, Acquisition Proposal, inquiry, discussions or negotiations, and the Company shall, as promptly as practicable (and in any event within 24 hours after receipt), provide to Parent copies of any written materials received by the Company in connection with any of the foregoing, and the identity of the Third Party making any such request, Acquisition Proposal or inquiry or with whom any discussions or negotiations are taking place. The Company shall keep Parent informed of any material developments, discussions or negotiations regarding any Acquisition Proposal on a reasonably current basis (and in any event within 24 hours) and shall notify Parent of the status of such Acquisition Proposal. The Company agrees that it and its Subsidiaries will not enter into any confidentiality agreement with any Person subsequent to the date hereof which prohibits the Company from providing any information to Parent in accordance with this Section 6.2. From and after the date hereof, the Company shall not grant any waiver, amendment or release under any standstill agreement without the prior written consent of Parent, and the Company will use its reasonable best efforts to enforce any such agreement at the request of or on behalf of Parent, including initiating and prosecuting litigation seeking appropriate equitable relief (where available) and, to the extent applicable, damages.

          (e) Neither the Company Board nor any committee thereof will (i) fail to make, change, qualify, withhold, withdraw or modify, or publicly propose to change, qualify, withhold, withdraw or modify, in a manner adverse to Parent, the Company Board Recommendation, (ii) fail to recommend against acceptance of any tender offer or exchange offer for the shares of Company Common Stock (other than the Offer) within ten Business Days after commencement of any such offer, (iii) take any action or make any recommendation or public statement in connection with any such offer, (iv) adopt, approve or recommend, or publicly propose to approve or recommend an Acquisition Proposal, (v) make any public statement inconsistent with the Company Board Recommendation, (vi) resolve or agree to take any of the actions described in subclauses (i) through (v) above (actions described in subclauses (i) through (vi) being referred to as a “Company Adverse Recommendation Change”).

          (f) Notwithstanding anything to the contrary in Section 6.2(e), prior to, but not after, the Acceptance Time, the Company Board may make a Company Adverse Recommendation Change if prior to taking such action, the Company Board has determined in good faith, after consultation with its financial advisor and outside legal counsel, that (A) in the case of an Acquisition Proposal such Acquisition Proposal constitutes a Superior Proposal and the failure to take such action would be inconsistent with the directors’ fiduciary duties under applicable Law or (B) in response to an Intervening Event and in the absence of an Acquisition Proposal, that failure to take such action in response to such Intervening Event would be inconsistent with the directors’ fiduciary duties under applicable Law. The Company Board shall not make a Company Adverse Recommendation Change pursuant to Section 6.2(f)(A) unless prior to taking such action (i) the Company has given Parent at least three Business Days prior written notice of its intention to take such action (which notice shall specify the material terms and conditions of any such Superior Proposal (including the identity of the Person making such Superior Proposal)) and has contemporaneously provided to Parent a copy of any proposed

transaction agreements with the Person making such Superior Proposal, (ii) the Company has negotiated, and has caused its Representatives to negotiate, in good faith with Parent during such notice period to enable Parent to revise the terms of this Agreement such that it would cause such Superior Proposal to no longer constitute a Superior Proposal, and (iii) the Company has complied in all material respects with its obligations under this Section 6.2. It is understood and agreed that, upon the expiration of such notice period, if the Company has not received from Parent a written proposal to amend the terms of this Agreement that the Company Board determines in good faith, after consultation with its financial advisor and outside legal counsel, to be at least as favorable, from a financial point of view, to the Company’s Stockholders as the Superior Proposal, the Company shall have the right to terminate this Agreement pursuant to Section 10.1(c)(ii) at any time thereafter. It is also understood and agreed that any amendment to the financial terms or other material terms of a Superior Proposal after delivery of a notice in respect of such Superior Proposal shall require delivery of another Notice and a three Business Day notice period in respect of such Superior Proposal pursuant to Section 6.2(f) shall commence. The Company Board shall not make a Company Adverse Recommendation Change pursuant to Section 6.2(f)(B) unless prior to taking such action, (i) the Company has given Parent at least three Business Days prior written notice of its intention to take such action (which notice shall provide a detailed description of the Intervening Event), (ii) the Company has negotiated, and has caused its Representatives to negotiate, in good faith with Parent during such notice period to enable Parent to revise the terms of this Agreement in such a manner that would obviate the need for taking such action as a result of such Intervening Event, (iii) following the end of such notice period, the Company Board shall have considered in good faith any changes to this Agreement proposed in writing by Parent, and shall have determined in good faith, after consultation with its financial advisor and outside legal counsel, that notwithstanding such proposed changes, failure to take such actions in response to an Intervening Event would be inconsistent with the directors’ fiduciary duties under applicable Law and (iv) the Company has complied in all material respects with its obligations under this Section 6.2. No Company Adverse Recommendation Change shall change the approval of this Agreement for purposes of Section 251 of the DGCL, and no Company Adverse Recommendation Change shall have the effect of causing any state (including Delaware) corporate takeover statute or other similar statute to be applicable to the transactions contemplated by this Agreement (including the Offer, the Merger and the Tender and Voting Agreements).

          (g) Nothing in this Agreement shall prohibit the Company Board from complying with its disclosure obligations under U.S. federal or state Law, including (i) taking and disclosing to the Company Stockholders a position contemplated by Rule 14e-2(a) and Rule 14d-9 under the Exchange Act, or (ii) making any “stop-look-and-listen” communication to the Company’s Stockholders pursuant to Rule 14d-9(f) under the Exchange Act; provided, however, that in no event shall any such requirement affect, eliminate or modify the obligations of the Company under, or the effect of any such actions under, this Section 6.2; and provided, further, that any such disclosure will be deemed to be a Company Adverse Recommendation Change unless the Board of Directors publicly reaffirms the Company Board Recommendation in such statement or in connection with such action.

          (h) The Company shall promptly inform its Representatives who have been engaged or are otherwise providing assistance in connection with the transactions contemplated

by this Agreement of the Company’s obligations under this Section 6.2. Without limiting the generality of the foregoing, the Company acknowledges and agrees that any violation of the restrictions set forth in this Section 6.2 by Representatives of the Company shall be deemed to be a breach of this Section 6.2 by the Company.

     6.3 Access to Information.

          (a) Subject to the Confidentiality Agreement, to the extent permitted by applicable Law and third party license, joint operating or similar agreements, the Company shall, and shall cause its Subsidiaries to, afford to Parent, and to the officers, employees, accountants, counsel, financial advisors and other Representatives of Parent, reasonable access (including access to core samples, well logs and seismic data, in each case that are in the possession of the Company or any of its Subsidiaries, and including for the purpose of planning for post-merger integration activities and transition planning with the employees of the Company and its Subsidiaries) during normal business hours during the period prior to the Effective Time to all the properties, books, contracts, commitments, personnel and records of the Company and its Subsidiaries, and, during such period, to the extent permitted by applicable Law, the Company shall furnish promptly all information concerning its and its Subsidiaries’ business, properties and personnel, in each case as Parent may reasonably request. Notwithstanding the foregoing, no actions shall be required to be taken pursuant to this Section 6.3 that would create a risk of loss or waiver of any attorney-client privilege; provided, however, that the Company shall use reasonable best efforts to allow for access and disclosure of information in a manner reasonably acceptable to Parent that does not result in the loss or waiver of the attorney-client privilege, violation of a contract or license, or a violation of Law (which efforts shall include entering into mutually acceptable joint defense agreements between the parties if doing so would reasonably permit the disclosure of information without violating applicable law or jeopardizing such attorney-client privilege). All information exchanged pursuant to this Section 6.3 shall be subject to the Confidentiality Agreement. No delivery of information or investigation shall affect the representations and warranties contained herein, or limit or otherwise affect the remedies available pursuant to this Agreement.

          (b) The Company shall, as promptly as practicable following the end of each calendar month prior to the Closing, provide Parent with the Company’s internal monthly financial and operating data for such month.

     6.4 Certain Litigation. The Company shall promptly advise Parent of any litigation commenced after the date hereof against the Company or any of its directors (in their capacity as such) by any Company Stockholders (on their own behalf or on behalf of the Company) relating to this Agreement or the transactions contemplated hereby, and shall keep Parent reasonably informed regarding any such litigation. The Company shall give Parent the opportunity to participate in the defense or settlement of any such stockholder litigation and agrees that it shall not settle or offer to settle any such stockholder litigation without the prior written consent of Parent (which consent shall not be unreasonably withheld, conditioned or delayed).

     6.5 Section 16(b) Exemption. The Company shall take all actions to cause the transactions contemplated by this Agreement and any other dispositions of equity securities of the Company (including derivative securities) in connection with the transactions contemplated

by this Agreement by each individual who is a director or executive officer of the Company to be exempt under Rule 16b-3 under the Exchange Act.

ARTICLE VII
COVENANTS OF PARENT AND MERGER SUB

     7.1 Directors’ and Officers’ Indemnification and Insurance.

          (a) Parent and Merger Sub agree that all rights to indemnification, advancement of expenses and exculpation by the Company now existing in favor of each Person who is now, or has been at any time prior to the date hereof or who becomes prior to the Effective Time an officer or director of the Company and its Subsidiaries (each an “Indemnified Party”) as provided in the Company’s Charter Documents, in each case as in effect on the date of this Agreement, or pursuant to any other Contracts in effect on the date hereof and disclosed in Section 7.1 of the Company Disclosure Letter, shall be assumed by the Surviving Corporation in the Merger, without further action, at the Effective Time and shall survive the Merger and shall remain in full force and effect in accordance with their terms, and, in the event that any proceeding is pending or asserted or any claim made during such period, until the final disposition of such proceeding or claim.

          (b) From and after the Effective Time, to the fullest extent permitted under applicable Law, Parent and the Surviving Corporation (the “Indemnifying Parties”) shall indemnify, defend and hold harmless each Indemnified Party against all losses, claims, damages, liabilities, costs, fees, expenses, judgments and fines arising in whole or in part out of actions or omissions in their capacity as such occurring at or prior to the Effective Time (including in connection with the transactions contemplated by this Agreement) or pertaining to the fact that the Indemnified Party is or was a fiduciary under any Employee Plan or is or was serving at the request of the Company as a director or officer of any other corporation, partnership, joint venture or other enterprise, whether asserted or claimed prior to, at or after the Effective Time to the fullest extent that the Company would have been permitted under applicable Law or the Company’s Charter Documents, in each case as in effect on the date of this Agreement. The Indemnifying Parties shall advance each Indemnified Party for any legal or other expenses reasonably incurred by such Indemnified Party in connection with investigating or defending any such losses, claims, damages, liabilities, costs, fees, expenses, judgments and fines to the fullest extent permitted under applicable Law, subject to the Surviving Corporation’s receipt of an undertaking by such Indemnified Party to repay such legal and other fees and expenses paid in advance if it is ultimately determined in a final and non-appealable judgment of a court of competent jurisdiction that such Indemnified Party is not entitled to be indemnified under applicable Law; provided, however, that the Surviving Corporation will not be liable for any settlement effected without the Surviving Corporation’s prior written consent (which consent shall not be unreasonably withheld or delayed).

          (c) Prior to the Effective Time, the Company shall, in consultation with Parent, and if the Company is unable to, Parent shall (or shall cause the Surviving Corporation co), as of the Effective Time, obtain and fully pay for “tail” insurance policies with a claims period of six years from the Effective Time with at least the same coverage and amounts and containing terms, conditions and levels of coverage that are not less advantageous to the

directors and officers of the Company and its Subsidiaries from an insurance carrier with the same or better rating as the Company’s insurance carrier as of the date of this Agreement, in each case with respect to claims arising out of or relating to events which occurred before or at the Effective Time (including in connection with the transactions contemplated by this Agreement). If such “tail” prepaid insurance policies have been obtained, Parent shall, and shall cause the Surviving Corporation, after the Effective Time to maintain such policies in full force and effect, for their full term, and to continue to honor its respective obligations thereunder. If the Company fails to obtain such “tail” prepaid insurance policies as of the Effective Time, the Surviving Corporation shall, and Parent shall cause the Surviving Corporation to, continue to maintain in effect for a period of six years after the Effective Time, if available, the current policies of directors’ and officers’ liability insurance maintained by the Company immediately prior to the Effective Time (provided that the Surviving Corporation may substitute therefor policies of at least the same coverage and amounts and containing terms that are not less advantageous to the directors and officers of the Company and its Subsidiaries when compared to the insurance maintained by the Company as of the date hereof from an insurance carrier with the same or better rating as the Company’s insurance carrier as of the date of this Agreement); provided, however, that in no event will the Surviving Corporation be required, nor shall the Company be permitted, to expend an annual premium for such coverage in excess of 300% of the last annual premium paid by the Company for such insurance prior to the date of this Agreement, which amount is set forth on Section 7.1(c) of the Company Disclosure Letter (the “Maximum Premium”). If such insurance coverage cannot be obtained at an annual premium equal to or less than the Maximum Premium, the Surviving Corporation will obtain, and Parent will cause the Surviving Corporation to obtain, that amount of directors’ and officers’ insurance (or “tail” coverage) obtainable for an annual premium equal to the Maximum Premium.

          (d) The obligations of Parent and the Surviving Corporation under this Section 7.1 shall survive the consummation of the Merger and shall not be terminated or modified in such a manner as to adversely affect any Indemnified Party to whom this Section 7.1 applies without the consent of such affected Indemnified Party (it being expressly agreed that the Indemnified Parties to whom this Section 7.1 applies and their heirs and legal representatives shall be third party beneficiaries of this Section 7.1, each of whom may enforce the provisions of this Section 7.1).

          (e) In the event Parent, the Surviving Corporation or any of their respective successors or assigns (i) consolidates with or merges into any other Person and shall not be the continuing or surviving corporation or entity in such consolidation or merger or (ii) transfers or conveys all or substantially all of its properties, rights and other assets to any Person, then, and in either such case, proper provision shall be made so that the successors and assigns of Parent or the Surviving Corporation, as the case may be, shall assume all of the obligations set forth in this Section 7.1. For six years after the Effective Time, the Indemnifying Parties agree, to the fullest extent permitted by applicable Law, to cause the Surviving Corporation’s (or any successor’s) Charter Documents to maintain the current provisions regarding elimination of liability of directors and indemnification of and advancement of expenses to directors, officers and employees of the Company that are contained in the Company’s Charter Documents as in effect on the date of this Agreement. The agreements and covenants contained herein shall not be deemed to be exclusive of any other rights to which any Indemnified Party is entitled, whether

pursuant to Law, Contract or otherwise. Nothing in this Agreement is intended to, shall be construed to or shall release, waive or impair any rights to directors’ and officers’ insurance claims under any policy that is or has been in existence with respect to the Company or its officers, directors and employees, it being understood and agreed that the indemnification provided for in this Section 7.1 is not prior to, or in substitution for, any such claims under any such policies.

     7.2 Employee Matters.

          (a) Parent hereby acknowledges that a “change of control,” or “change in control” or “fundamental change” within the meaning of the Employee Plans, as applicable, will occur as of the Acceptance Time or Effective Time, as applicable.

          (b) As of the Effective Time, the Surviving Corporation and its Subsidiaries shall (and Parent shall cause the Surviving Corporation and its Subsidiaries to) honor all Employee Plans and compensation arrangements in accordance with their terms as in effect immediately prior to the Acceptance Time, provided that nothing in this sentence shall prohibit the Surviving Corporation from amending or terminating, or from causing the Surviving Corporation to amend or terminate, any such Employee Plans, arrangements or agreements in accordance with their terms or if otherwise required by applicable Law. The Company will take such action as it determines to be necessary or appropriate prior to the Effective Time to cause all participants in the Company’s 401(k) plan to become fully vested in all of their account balances thereunder upon the Effective Time.

          (c) For a period of one year following the Effective Time, the Surviving Corporation or its Subsidiary shall (and Parent shall cause the Surviving Corporation or its Subsidiary to) provide (i) at least the same level of base salary or base wages to each Continuing Employee as the base salary or base wages provided to each Continuing Employee immediately prior to the Effective Time, and (ii) benefits and severance payments (other than equity based benefits, change in control benefits and individual employment agreements) to each Continuing Employee that, taken as a whole, are substantially similar in the aggregate to the benefits and severance payments (other than equity based benefits, change in control benefits and individual employment agreements) provided to either similarly situated employees of Parent and its Subsidiaries or similarly situated employees of the Company and its Subsidiaries immediately prior to the Effective Time.

          (d) The Company 2011 Performance Bonus Plan and the Company 2011 401(k) Matching Plan shall be continued on behalf of eligible Continuing Employees for the remainder of the 2011 calendar year based upon Company performance during 2011, with the resulting payments and contributions for 2011 to be made in the first quarter of 2012 similar to the timing of such payments and contributions in prior years.

          (e) To the extent that an Employee Plan or employee benefit plan of Parent is made available to any Continuing Employee on or following the Effective Time, the Surviving Corporation shall (and Parent shall cause the Surviving Corporation to) cause to be granted to such Continuing Employee credit for all service with the Company and its Subsidiaries (and their predecessors) prior to the Effective Time for purposes of eligibility to participate, vesting and

entitlement to benefits where length of service is relevant (including, but not limited to, for purposes of vacation, sick and paid time off accrual and severance pay entitlement); provided, however, that such service need not be credited (i) to the extent that it would result in duplication of coverage or benefits, (ii) to the extent service during a period is not recognized under any such plan, or (iii) under any new plan or arrangement to the extent that such plan or arrangement does not provide prior service credit to employees generally. In addition, and without limiting the generality of the foregoing, at the Effective Time: (i) each Continuing Employee shall be immediately eligible to participate, without any waiting time, in any and all employee benefit plans sponsored by the Surviving Corporation and its Subsidiaries (other than the Employee Plans) (such plans, collectively, the “New Plans”) to the extent coverage under any such New Plan replaces coverage under a comparable Employee Plan in which such Continuing Employee participates immediately before the Acceptance Time (such plans, collectively, the “Old Plans”); and (ii) for purposes of each New Plan providing medical, dental, pharmaceutical, vision and/or disability benefits to any Continuing Employee, the Surviving Corporation shall cause all waiting periods, pre-existing condition exclusions, evidence of insurability requirements and actively-at-work or similar requirements of such New Plan to be waived for such Continuing Employee and his or her covered dependents to the extent such requirements had been met under the Old Plan which such New Plan replaced, and the Surviving Corporation shall cause any eligible expenses incurred by such Continuing Employee and his or her covered dependents during the portion of the plan year of the Old Plan ending on the date such employee’s participation in the corresponding New Plan begins to be given full credit under such New Plan for purposes of satisfying all deductible, coinsurance and maximum out-of-pocket requirements applicable to such Continuing Employee and his or her covered dependents for the applicable plan year as if such amounts had been paid in accordance with such New Plan, and (iii) the Surviving Corporation shall credit the accounts of such Continuing Employees under any New Plan which is a flexible spending plan with any unused balance in the account of such Continuing Employee under the applicable Employee Plan. Any vacation or paid time off accrued but unused by a Continuing Employee as of immediately prior to the Effective Time shall be credited to such Continuing Employee following the Effective Time.

          (f) Notwithstanding anything to the contrary set forth in this Agreement, no provision of this Agreement shall be deemed to (i) guarantee employment for any Continuing Employee for any period of time, or preclude the ability of Parent or the Surviving Corporation to terminate the employment of any Continuing Employee for any reason, or (ii) subject to the limitations and requirements specifically set forth in this Section 7.2, require Parent or the Surviving Corporation to continue any Employee Plan or prevent the amendment, modification or termination thereof after the Effective Time provided that such action does not violate the terms and conditions of such Employee Plans or applicable Law.

          (g) This Section 7.2 shall be binding upon and inure solely to the benefit of each of the parties to this Agreement, and nothing in this Section 7.2, expressed or implied, is intended to confer upon any other Person any rights or remedies of any nature whatsoever under or by reason of this Section 7.2. Without limiting the foregoing, no provision of this Section 7.2 will create any third party beneficiary rights in any current or former employee, director or consultant (including any beneficiary or dependent thereof) of the Company or any of its Subsidiaries in respect of continued employment (or resumed employment) or any other matter,

provided that nothing in this Agreement shall relieve the Parent or the Surviving Corporation or its Subsidiaries of their obligations to the Continuing Employees (or any former employee) (who, together with their heirs and legal representatives, shall be third party beneficiaries of this Agreement) as the successor to the Company or its Subsidiaries under any agreements disclosed on Section 7.2(g) of the Company Disclosure Letter, as disclosed in the Company SEC Reports, or pursuant to the Company Change in Control Plan, the Company Key Employee Change in Control Plan or the Company Key Employee Change in Control Retention Plan adopted by the Company on September 13, 2011 or any other plan, program, policy, agreement or arrangement of the Company or its Subsidiaries, except as otherwise specifically provided in this Agreement.

Except as expressly contemplated by Section 6.2(f) and Section 6.2(g), the Proxy Statement shall include the Company Board Recommendation. The Company will use reasonable best efforts to cause the Proxy Statement, at the time of the mailing of the Proxy Statement or any amendments or supplements thereto, and at the time of the Company Stockholder Meeting, to not 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 were made, not misleading; provided, however, that no representation or warranty is made by the Company with respect to information supplied by Parent or Merger Sub for inclusion or incorporation by reference in the Proxy Statement.

At such Company Stockholder Meeting following any Company Adverse Recommendation Change, the Company may submit this Agreement and the transactions contemplated hereby (including the Merger) without a recommendation or with a negative recommendation (although the approval of this Agreement by the Company Board may not be rescinded unless this Agreement is terminated in accordance with Article X), in which event the Company Board may communicate the basis for its lack of a recommendation or negative recommendation to its stockholders in the Proxy Statement or an appropriate amendment or supplement thereto. The Company shall, upon the reasonable request of Parent, advise Parent at least on a daily basis on each of the last seven Business Days prior to the date of the Company Stockholder Meeting as to the aggregate tally of proxies received by the Company with respect to the Requisite Stockholder Approval. Without the prior written consent of Parent, the adoption of this Agreement and the transactions contemplated hereby (including the Merger) shall be the only matter (other than procedure matters) which the Company shall propose to be acted on by the Company Stockholders at the Company Stockholder Meeting.

          (d) Amendments to Proxy Statement. If at any time prior to the Effective Time any event or circumstance relating to the Company or any of its Subsidiaries or its or their respective officers or directors should be discovered by the Company which, pursuant to the Exchange Act, should be set forth in an amendment or a supplement to the Proxy Statement, if necessary, they shall promptly inform Parent.

          (e) Short Form Merger. Notwithstanding the foregoing, if, following the Acceptance Time and the exercise, if any, of the Top-Up Option, Parent and its Affiliates shall

own at least 90% of the outstanding shares of the Company Common Stock, the parties hereto shall take all necessary and appropriate action, including with respect to the transfer to Merger Sub of any shares of Company Common Stock held by Parent or its Affiliates, to cause the Merger to become effective as soon as practicable after the Acceptance Time without the Company Stockholder Meeting in accordance with Section 253 of the DGCL.

     8.4 Anti-Takeover Laws. In the event that any state anti-takeover or other similar Law is or becomes applicable to this Agreement or any of the transactions contemplated by this Agreement, the Company, Parent and Merger Sub shall use their respective reasonable best efforts to ensure that the transactions contemplated by this Agreement may be consummated as promptly as practicable on the terms and subject to the conditions set forth in this Agreement and otherwise to minimize the effect of such Law on this Agreement and the transactions contemplated hereby.

     11.3 Assignment. Neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned, in whole or in part, by operation of Law or otherwise by any of the parties hereto without the prior written consent of the other parties hereto, and any purported assignment without such consent shall be null and void; provided, however, that Merger Sub, upon prior notice to the Company, may assign, in its sole discretion, any of or all its rights, interests and obligations hereunder to Parent or to any direct or indirect wholly owned Subsidiary of Parent, in which event all references herein to Merger Sub shall be deemed references to such other Subsidiary except that all representations and warranties made herein with respect to Merger Sub as of the date of this Agreement shall be deemed representations and warranties made with respect to such other Subsidiary as of the date of such designation; and provided, further, that no such assignment shall relieve Merger Sub of any of its obligations under this Agreement or may be made if it would materially impede or delay the consummation of the transactions contemplated by this Agreement. Subject to the preceding sentence, this Agreement shall be binding upon and shall inure to the benefit of the parties hereto and their respective successors and permitted assigns.

     11.4 Entire Agreement. This Agreement, together with the Company Disclosure Letter and any other schedules, exhibits or annexes hereto, and the Confidentiality Agreement, constitute the entire agreement among the parties hereto with respect to the subject matter of this Agreement and supersede all other prior agreements and understandings (whether written or oral), by or among the parties to this Agreement, with respect to the subject matter hereof and thereof. In the event of any inconsistency between the statements in the body of this Agreement, the Confidentiality Agreement and the Company Disclosure Letter (other than an exception expressly set forth as such in the Company Disclosure Letter), the statements in the body of this Agreement will control.

     11.5 No Third Party Beneficiaries. Except as provided in Section 7.1 (which from and after the Effective Time shall be to the benefit of, and may be enforced by, the parties referred to in such section), this Agreement is for the sole benefit of the parties hereto and their respective successors and permitted assigns and nothing herein, express or implied, is intended to or shall confer upon any other Person any legal or equitable right, benefit or remedy of any nature whatsoever under or by reason of this Agreement.

     11.6 Severability. If any term or provision of this Agreement is invalid, illegal or unenforceable in any jurisdiction, such invalidity, illegality or unenforceability shall not affect any other term or provision of this Agreement or invalidate or render unenforceable such term or provision in any other jurisdiction. Upon such determination that any term or other provision is invalid, illegal or unenforceable, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in a mutually acceptable manner in order that the transactions contemplated hereby be consummated as originally contemplated to the greatest extent possible.

     11.7 Specific Performance. The parties hereto agree and acknowledge that irreparable damage would occur and that the parties would not have any adequate remedy at Law in the event that any of the terms or provisions of this Agreement are not performed in accordance with their specific terms, and that, in addition to any other remedy that each party hereto may have under Law or equity, the non-breaching party hereto shall be entitled to injunctive relief to prevent breaches of this Agreement and to an Order or decree to enforce specifically the performance of the terms and provisions hereof.

     11.8 Governing Law. This Agreement shall be governed by, and construed in accordance with, the Laws of the State of Delaware without giving effect to any choice or conflict of law provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of Laws of any jurisdiction.

     11.9 Submission to Jurisdiction. Each of the parties hereto irrevocably agrees that any legal action or proceeding with respect to this Agreement and the rights and obligations arising hereunder, or for recognition and enforcement of any judgment in respect of this Agreement and the rights and obligations arising hereunder shall be brought and determined exclusively in the Court of Chancery of the State of Delaware, or in the event (but only in the event) that the Court of Chancery of the State of Delaware or the Delaware Supreme Court determines that, notwithstanding Section 111 of the DGCL, the Court of Chancery does not have or should not exercise subject matter jurisdiction over such matter, the Superior Court of the State of Delaware

or the federal courts of the United States located in the State of Delaware. Each of the parties hereto agrees that mailing of process or other papers in connection with any such action or proceeding in the manner provided in Section 11.2 or in such other manner as may be permitted by applicable Laws, will be valid and sufficient service thereof. Each of the parties hereto hereby irrevocably submits with regard to any such action or proceeding for itself and in respect of its property, generally and unconditionally, to the personal jurisdiction of the aforesaid courts and agrees that it will not bring any action relating to this Agreement or any of the transactions contemplated by this Agreement in any court or tribunal other than the aforesaid courts. Each of the parties hereto hereby irrevocably waives, and agrees not to assert, by way of motion, as a defense, counterclaim or otherwise, in any action or proceeding with respect to this Agreement and the rights and obligations arising hereunder, or for recognition and enforcement of any judgment in respect of this Agreement and the rights and obligations arising hereunder (i) any claim that it is not personally subject to the jurisdiction of the above named courts for any reason other than the failure to serve process in accordance with this Section 11.9, (ii) any claim that it or its property is exempt or immune from jurisdiction of any such court or from any legal process commenced in such courts (whether through service of notice, attachment prior to judgment, attachment in aid of execution of judgment, execution of judgment or otherwise), and (iii) to the fullest extent permitted by the applicable Law, any claim that (x) the suit, action or proceeding in such court is brought in an inconvenient forum, (y) the venue of such suit, action or proceeding is improper, or (z) this Agreement, or the subject matter hereof, may not be enforced in or by such courts.

     11.10 WAIVER OF JURY TRIAL. EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES AND, THEREFORE, EACH SUCH PARTY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LEGAL ACTION ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT. EACH PARTY TO THIS AGREEMENT CERTIFIES AND ACKNOWLEDGES THAT (A) NO REPRESENTATIVE OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT SEEK TO ENFORCE THE FOREGOING WAIVER IN THE EVENT OF A LEGAL ACTION, (B) SUCH PARTY HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (C) SUCH PARTY MAKES THIS WAIVER VOLUNTARILY, AND (D) SUCH PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 11.10.

     11.11 Fees and Expenses. Except as set forth in Section 10.3, all costs, fees and expenses incurred in connection with this Agreement and the transactions contemplated hereby shall be paid by the party or parties, as applicable, incurring such expenses whether or not the Offer or the Merger is consummated.

     11.12 Counterparts. This Agreement may be executed in any number of counterparts, all of which shall be considered one and the same agreement. This Agreement shall become

ANNEX A

CONDITIONS TO THE OFFER

     Notwithstanding any other provisions of the Offer, but subject to compliance with the terms and conditions of the Agreement (capitalized terms that are used but not otherwise defined in this Annex A shall have the respective meanings ascribed thereto in the Agreement), Merger Sub shall not be required to, and Parent shall not be required to cause Merger Sub to, accept for payment or pay for any shares of Company Common Stock tendered pursuant to the Offer (and not theretofore accepted for payment or paid for) unless, at the expiration of the Offer: (A) the waiting period (and extensions thereof) applicable to the transactions contemplated by this Agreement under the HSR Act shall have expired or been terminated (the “HSR Condition”);(B) the Minimum Condition shall have been satisfied; and (C) none of the following conditions shall have occurred and be continuing immediately prior to the expiration of the Offer:

          (1) (i) there shall be pending any Legal Proceeding by any Governmental Authority of competent jurisdiction (A) seeking to enact, issue, promulgate, enforce or enter any Law or Order that has the effect of making the consummation of the Offer or the Merger illegal or which has the effect of prohibiting, restraining or otherwise preventing the consummation of the Offer or the Merger, or (B) seeking to impose, or requiring that the parties agree to, any conditions, restrictions or other measures necessary to satisfy the HSR Condition that would result, individually or in the aggregate, in any Adverse Regulatory Effect or (ii) there shall (x) be in effect any Law or Order that has the effect of making the consummation of the Offer or the Merger illegal or which has the effect of prohibiting, restraining or otherwise preventing the consummation of the Merger or (y) have been imposed by any Governmental Authority of competent jurisdiction any conditions, restrictions or other measures necessary to satisfy the HSR Condition that, individually or in the aggregate, result in any Adverse Regulatory Effect;

          (2) (i) any of the representations and warranties of the Company set forth in the Agreement (other than those set forth in Sections 2.2(a), 4.1(a), 4.2, 4.5(a), 4.5(b), and 4.5(d)) shall not have been true and correct in all respects as of immediately prior to the expiration of the Offer with the same force and effect as if made on and as of such date (unless such representation or warranty expressly relates to an earlier date, in which case on and as of such earlier date), except for any failure to be so true and correct which has not had and would not reasonably be expected to have, individually or in the aggregate, a Company Material Adverse Effect or (ii) any of the representations and warranties set forth in Sections 2.2(a), 4.1(a), 4.2, 4.5(a), 4.5(b), and 4.5(d) shall not be true and correct in all respects as of immediately prior to the expiration of the Offer with the same force and effect as if made on and as of such date (unless such representation or warranty expressly relates to an earlier date, in which case on and as of such earlier date), except for any failures of the representations or warranties in Sections 4.5(a), 4.5(b) and 4.5(d) to be so true and correct which, individually or in the aggregate, are immaterial in nature or amount; provided, however, that, for purposes of determining the accuracy of the representations and warranties of the Company set forth in the Agreement for purposes of clause (i) above, all materiality and “Company Material Adverse

Effect” qualifications set forth in such representations and warranties shall be omitted and disregarded;

          (3) the Company shall have failed to perform in any material respects all obligations required to be performed by it under the Agreement at or prior to the expiration of the Offer, except as set forth in the Company Disclosure Letter;

          (4) any change, effect, occurrence, development or circumstance shall have occurred that, individually or in the aggregate, has had or would reasonably be expected to have a Company Material Adverse Effect;

          (5) the Company shall have failed to furnish Parent with a certificate dated as of the date of the expiration of the Offer signed on its behalf by its Chief Executive Officer or Chief Financial Officer stating that the conditions set forth in clauses (2), (3) and (4) shall have been satisfied; or

          (6) the Agreement shall have been terminated in accordance with its terms.

     The foregoing conditions shall be for the sole benefit of Parent and Merger Sub and may be asserted by Parent or Merger Sub regardless of the circumstances giving rise to any such conditions and may be waived by Parent or Merger Sub in whole or in part at any time and from time to time, in each case except for the Minimum Condition and the HSR Condition, in its sole discretion, subject to the terms of this Agreement and applicable Law. Unless waived by Parent or Merger Sub in a notice to the Company, any shares of Company Common Stock subject to notices of guaranteed delivery shall be deemed not to be validly tendered for purposes of satisfying the Minimum Condition unless and until the shares underlying such notices of guaranteed delivery are delivered to or on behalf of Parent or Merger Sub. Any reference in this Annex A or elsewhere in the Agreement to a condition or requirement being satisfied shall be deemed to be satisfied if such condition or requirement is so waived. The failure by Parent or Merger Sub at any time to exercise any of the foregoing rights shall not be deemed a waiver of any such right and each such right may be deemed an ongoing right that may be asserted at any time and from time to time. Each of the foregoing conditions is independent of any of the other foregoing conditions; the exclusion of any event from a particular condition does not mean that such event may not be included in another condition.

ANNEX B

FORM OF

AMENDED AND RESTATED

CERTIFICATE OF INCORPORATION

OF

BRIGHAM EXPLORATION COMPANY

     FIRST: The name of the corporation is Brigham Exploration Company (the “Corporation”).

     SECOND: The address of its registered office in the State of Delaware is 1209 Orange Street, in the City of Wilmington, County of New Castle 19801. The name of its registered agent at such address is The Corporation Trust Company.

     THIRD: The nature of the business or purposes to be conducted or promoted is to engage in any lawful act or activity for which corporations may be organized under the General Corporation Law of the State of Delaware (the “DGCL”).

     FOURTH: The total number of shares of all classes of stock which the Corporation shall have authority to issue is 1,000 shares of common stock, par value $0.01 per share (the “Common Stock”). Each share of Common Stock is entitled to one vote.

     FIFTH: Unless and except to the extent that the bylaws of the Corporation shall so require, the election of directors of the Corporation need not be by written ballot.

     SIXTH: In furtherance of, and not in limitation of, the powers conferred by statute, the bylaws of the Corporation may be altered, amended or repealed and new bylaws may be adopted by the Board of Directors of the Corporation (the “Board”), unless the bylaws of the Corporation limit or eliminate the Board’s power to amend, alter or repeal the bylaws or to adopt new bylaws.

     SEVENTH: Whenever a compromise or arrangement is proposed between the Corporation and its creditors or any class of them and/or between the Corporation and its stockholders or any class of them, any court of equitable jurisdiction within the State of Delaware may, on the application in a summary way of the Corporation or of any creditor or stockholder thereof or on the application of any receiver or receivers appointed for the Corporation under Section 291 of the DGCL or on the application of trustees in dissolution or of any receiver or receivers appointed for the Corporation under Section 279 of the DGCL, order a meeting of the creditors or class of creditors, and/or of the stockholders or class of stockholders of the Corporation, as the case may be, to be summoned in such manner as the said court directs. If a majority in number representing three fourths in value of the creditors or class of creditors, and/or of the stockholders or class of stockholders of the Corporation, as the case may be, agree to any compromise or arrangement and to any reorganization of the Corporation as a consequence of such compromise or arrangement, the said compromise or arrangement and the

said reorganization shall, if sanctioned by the court to which the said application has been made, be binding on all the creditors or class of creditors, and/or on all the stockholders or class of stockholders, of the Corporation, as the case may be, and also on the Corporation.

     EIGHTH: Elimination of Certain Liability of Directors. (a) To the fullest extent permitted by the DGCL as the same exists or may hereafter be amended, a director of the Corporation shall not be personally liable to the Corporation or its stockholders for monetary damages for breach of duty as a director. Without limiting the foregoing in any respect, a director of the Corporation shall not be personally liable to the Corporation or its stockholders for monetary damages for breach of duty as a director, except for liability (i) for any breach of the director’s duty of loyalty to the Corporation or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the DGCL, or (iv) for any transaction from which the director derived an improper personal benefit. If the DGCL is amended to authorize corporate action further eliminating or limiting the personal liability of directors, then the liability of a director of the Corporation shall be eliminated or limited to the fullest extent permitted by the DGCL, as so amended. Any repeal or modification of this provision shall not adversely affect any right or protection of a director of the Corporation existing at the time of such repeal or modification.

     (b) Indemnification and Insurance.

     (i) Right to Indemnification. (A) Each person who was or is made a party or is threatened to be made a party to or is involved in any action, suit or proceeding, whether civil, criminal, administrative or investigative (hereinafter a “proceeding”), by reason of the fact that he or she, or a person of whom he or she is the legal representative, is or was a director or officer of the Corporation, or serves, in any capacity, any corporation, partnership or other entity in which the Corporation has a partnership or other interest, including service with respect to employee benefit plans, whether the basis of such proceeding is alleged action in an official capacity as a director, officer, employee or agent or in any other capacity while serving as a director, officer, employee or agent, shall be indemnified and held harmless by the Corporation to the fullest extent authorized by the DGCL, as the same exists or may hereafter be amended (but, in case of any such amendment, only to the extent that such amendment permits the Corporation to provide broader indemnification rights than said law permitted the Corporation to provide prior to such amendment), against all expense, liability and loss (including attorneys’ fees, judgments, fines, ERISA excise taxes or penalties and amounts paid or to be paid in settlement) reasonably incurred or suffered by such person in connection therewith and such indemnification shall continue as to a person who has ceased to be a director, officer, employee or agent and shall inure to the benefit of his or her heirs, executors and administrators, and (B) the Corporation shall indemnify and hold harmless in such manner any person designated by the Board, or any committee thereof, as a person subject to this indemnification provision, and who was or is made a party or is threatened to be made a party to a proceeding by reason of the fact that he, she or a person of whom he or she is the legal representative, is or was serving at the request of the Board of the Corporation as a director, officer, employee or agent of another

corporation or a partnership, joint venture, trust or other enterprise whether such request is made before or after the acts taken or allegedly taken or events occurring or allegedly occurring which give rise to such proceeding; provided, however, that except as provided in subsection (b)(ii) of this Section, the Corporation shall indemnify any such person seeking indemnification pursuant to this subsection in connection with a proceeding (or part thereof) initiated by such person only if such proceeding (or part thereof) was authorized by the Board. The right to indemnification conferred herein shall be a contract right based upon an offer from the Corporation which shall be deemed to have been made to a person subject to subsection (b)(i)(A) on the date hereof and to a person subject to subsection (b)(i)(B) on the date designated by the Board, shall be deemed to be accepted by such person’s service or continued service as a director or officer of the Corporation for any period after the offer is made and shall include the right to be paid by the Corporation the expenses incurred in defending any such proceeding in advance of its final disposition; provided, however, that if the DGCL requires, the payment of such expenses incurred by a director or officer in his or her capacity as the director or officer (and not in any other capacity in which service was or is rendered by such person while a director or officer, including, without limitation, service to an employee benefit plan) in advance of the final disposition of a proceeding, shall be made only upon delivery to the Corporation of an undertaking, by or on behalf of such director or officer, to repay all amounts so advanced if it shall ultimately be determined that such director or officer is not entitled to be indemnified under this Section or otherwise. The Corporation may, by action of the Board, provide indemnification to employees or agents of the Corporation with the same scope and effect as the foregoing indemnification of directors and officers.

     (ii) Right of Claimant to Bring Suit. If a claim under Section (b)(i) of this Article is not paid in full by the Corporation within thirty days after a written claim has been received by the Corporation, the claimant may at any time thereafter bring suit against the Corporation to recover the unpaid amount of the claim and, if successful in whole or in part, the claimant shall be entitled to be paid also the expense of prosecuting such claim. It shall be a defense to any such action (other than an action brought to enforce a claim for expenses incurred in defending any proceeding in advance of its final disposition where the required undertaking, if any is required, has been tendered to the Corporation) that the claimant has not met the standards of conduct which make it permissible under the DGCL for the Corporation to indemnify the claimant for the amount claimed. Neither the failure of the Corporation (including the Board, independent legal counsel, or its stockholders) to have made a determination prior to the commencement of such action that indemnification of the claimant is proper in the circumstances because he or she has met the applicable standard of conduct set forth in the DGCL, nor an actual determination by the Corporation (including the Board, independent legal counsel, or its stockholders) that the claimant has not met such applicable standard of conduct, shall be a defense to the action or create a presumption that the claimant has not met the applicable standard of conduct.

     (iii) Nonexclusivity of Rights. The right to indemnification and the payment of expenses incurred in defending a proceeding in advance of its final disposition

conferred in this Section shall not be exclusive of any right which any person may have or hereafter acquire under any statute, provision of the Certificate of Incorporation, by-law, agreement, vote of stockholders or disinterested directors or otherwise.

     (iv) Insurance. The Corporation may maintain insurance, at its expense, to protect itself and any director officer, employee or agent of the Corporation or another corporation, partnership, joint venture, trust or other enterprise against any such expense, liability or loss, whether or not the corporation would have the power to indemnify such person against such expense, liability or loss under the DGCL.

     (v) Nature of Rights. The rights conferred upon indemnitees in this Article EIGHTH shall be contract rights and such rights shall continue as to an indemnitee who has ceased to be a director, officer, employee or agent and shall inure to the benefit of the indemnitee’s heirs, executors and administrators. Any amendment, alteration or repeal of this Article EIGHTH that adversely affects any right of an indemnitee or its successors shall be prospective only and shall not limit, eliminate, or impair any such right with respect to any proceeding involving any occurrence or alleged occurrence of any action or omission to act that took place prior to such amendment or repeal.

     (vi) Severability. If any subsection of this Section (b) shall be deemed to be invalid or ineffective in any proceedings, the remaining subsections hereof shall not be affected and shall remain in full force and effect.

     NINTH: The Corporation shall have the right, subject to any express provisions or restrictions contained in this Certificate of Incorporation or bylaws of the Corporation, from time to time, to amend this Certificate of Incorporation or any provision hereof in any manner now or hereafter provided by law, and all rights and powers of any kind conferred upon a director or stockholder of the Corporation by this Certificate of Incorporation or any amendment hereof are subject to such right of the Corporation.
