Such holder shall be entitled to payment, solely from the Surviving Corporation, of the appraisal value of the Dissenting Shares held by them to the extent permitted by and in accordance with the provisions of section 262 of the DGCL; provided, however, that (i) if any holder of Dissenting Shares, under the circumstances permitted by and in accordance with the DGCL, shall have effectively withdrawn his demand for appraisal of such Dissenting Shares or lost his right to appraisal and payment for his shares of Burlington Common Stock under section 262 of DGCL, (ii) if any holder of Dissenting Shares shall have failed to establish his entitlement to appraisal rights as provided in section 262 of the DGCL or (iii) if any holder of Dissenting Shares takes or fails to take any action the consequence of which is that such holder is not entitled to payment for his shares under the DGCL, such holder or holders (as the case may be) shall forfeit the right to appraisal of such shares of Burlington Common Stock and such Burlington Common Stock shall thereupon cease to constitute Dissenting Shares. Burlington shall give ConocoPhillips prompt notice of any demands received by Burlington for appraisal of shares of Burlington Common Stock, and ConocoPhillips shall have the right to participate in all negotiations and proceedings with respect to such demands. Burlington shall not settle, make any payments with respect to, or offer to settle, any claim with respect to Dissenting Shares without the written consent of ConocoPhillips. 3.3 Stock Options and Equity Awards. (a) The Board of Directors of Burlington shall take such action as is necessary so that at the Effective Time, each outstanding option to purchase shares of Burlington Common Stock (a "Burlington Stock Option") granted under the Burlington Stock Plans, whether or not vested, shall cease to represent a right to acquire shares of Burlington Common Stock and shall thereafter constitute a fully vested option (a "Converted ConocoPhillips Option") to acquire (on the same terms and conditions as were applicable to such Burlington Stock Option pursuant to the relevant Burlington Stock Plan under which it was issued and the agreement evidencing the grant thereof prior to the Effective Time) the number (rounded down to the nearest whole number) of shares of ConocoPhillips Common Stock determined by multiplying (A) the number of shares of Burlington Common Stock subject to such Burlington Stock Option immediately prior to the Effective Time by (B) the Stock Award Exchange Ratio. The exercise price or base price per share of ConocoPhillips Common Stock subject to any such Converted ConocoPhillips Option shall be an amount (rounded up to the nearest one hundredth of a cent) equal to (A) the exercise price or base price per share of Burlington Common Stock subject to such Burlington Stock Option immediately prior to the Effective Time divided by (B) the Stock Award Exchange Ratio. Notwithstanding the foregoing, any Burlington Stock Option which is an "incentive stock option" (as defined in Section 422 of the Code) shall be adjusted in accordance with the requirements of Section 424 of the Code. Prior to the Effective Time, Burlington shall make any amendments to the terms of the Burlington Stock Plans as are necessary to give effect to the transactions contemplated by this Section 3.3(a). For purposes of this Section 3.3(a), the "Stock Award Exchange Ratio" shall mean the sum of (i) the Exchange Ratio plus (ii) the fraction resulting from dividing the Per Share Cash Amount by the closing price per share of the ConocoPhillips Common Stock on the NYSE on the last trading day immediately preceding the Closing Date. (b) At the Effective Time each outstanding restricted share of Burlington Common Stock granted pursuant to a Burlington Stock Plan shall vest. Following the Effective Time, no holder of a Burlington incentive award or other compensatory award shall have any right to receive shares of Burlington Common Stock in respect of such award. (c) At the Effective Time, each Burlington Stock Unit shall cease to be measured by the value of a number of shares of Burlington Common Stock and shall instead be measured by the value of a number of shares of ConocoPhillips Common Stock determined by multiplying (x) the number of shares of Burlington Common Stock by which such Burlington Stock Unit is measured immediately prior to the Effective Time by (y) the Stock Award Exchange Ratio. (d) Prior to the Effective Time, Burlington (or its Board of Directors or the appropriate committee thereof) shall take all corporate action necessary for the adjustment of Burlington Stock Options and Burlington Stock Units contemplated by this Section 3.3. ConocoPhillips shall take all corporate action necessary to assume as of the Effective Time Burlington's obligations with respect to the Converted ConocoPhillips Options and to reserve for issuance a sufficient number of shares of ConocoPhillips Common Stock for delivery upon the exercise of the Converted ConocoPhillips Option pursuant to the terms set forth in this Section 3.3. Not later than two Business Days after the Effective Time, ConocoPhillips shall file with the SEC a registration statement on an appropriate form or a post-effective amendment to a previously filed registration statement under the Securities Act with respect to the ConocoPhillips Common Stock to be issued upon the exercise of the Converted ConocoPhillips Options, shall deliver an applicable prospectus relating to such registration statement and shall maintain the effectiveness of such registration statement and prospectus for so long as such options remain outstanding. 3.4 Shares Held by Burlington Affiliates. Anything to the contrary herein notwithstanding, no shares of ConocoPhillips Common Stock (or certificates therefor) shall be issued in exchange for any Certificate to any "affiliate" of Burlington (identified pursuant to Section 6.12) until such Person shall have delivered to ConocoPhillips duly executed letters as contemplated by Section 6.12. Such Persons shall be subject to the restrictions described in such letters. 3.5 Surrender and Payment. (a) Prior to the Effective Time, ConocoPhillips shall appoint Mellon Investor Services LLC or such other exchange agent reasonably acceptable to Burlington (the "Exchange Agent") for the purpose of exchanging Certificates representing shares of Burlington Common Stock and non-certificated shares represented by book entry ("Book-Entry Shares") for the Merger Consideration. At or prior to the Effective Time, ConocoPhillips shall deposit with the Exchange Agent, in trust for the benefit of the holders of shares of Burlington Common Stock, (a) certificates representing shares of ConocoPhillips Common Stock and (b) cash, to be issued and paid pursuant to Section 3.1(a) and Section 3.6 in respect of shares of Burlington Common Stock converted pursuant to Section 3.1(a) in exchange for outstanding shares of Burlington Common Stock upon due surrender of Certificates pursuant to this Article III. Following the Effective Time, ConocoPhillips agrees to make available to the Exchange Agent, from time to time as needed, cash sufficient to pay any dividends and other distributions pursuant to Section 3.5(f). Any cash and certificates representing ConocoPhillips Common Stock deposited with the Exchange Agent (including the amount of any dividends or other distributions payable with respect thereto and such cash in lieu of fraction shares to be paid pursuant to Section 3.6) shall hereinafter be referred to as the "Exchange Fund"). Promptly after the Effective Time, ConocoPhillips will send, or will cause the Exchange Agent to send, to each holder of record of shares of Burlington Common Stock as of the Effective Time, a letter of transmittal for use in such exchange (which shall specify that the delivery shall be effected, and risk of loss and title shall pass, only upon proper delivery of the Certificates to the Exchange Agent) in such form as Burlington and ConocoPhillips may reasonably agree, for use in effecting delivery of shares of Burlington Common Stock to the Exchange Agent. Exchange of any Book-Entry Shares shall be effected in accordance with ConocoPhillips' customary procedures with respect to securities represented by book entry. (b) Each holder of shares of Burlington Common Stock that have been converted into a right to receive the Merger Consideration, upon surrender to the Exchange Agent of a Certificate, together with a properly completed letter of transmittal, will be entitled to receive (A) one or more shares of ConocoPhillips Common Stock (which shall be in non-certificated book-entry form unless a physical certificate is requested) representing, in the aggregate, the whole number of shares of ConocoPhillips Common Stock, if any, that such holder has the right to receive pursuant to Section 3.1 and (B) a check in the amount equal to the cash portion of the Merger Consideration, if any, that such holder has the right to receive pursuant to Section 3.1 and this Article 3, including cash payable in lieu of fractional shares pursuant to Section 3.6 and dividends and other distributions pursuant to Section 3.5(f). No interest shall be paid or accrued on any Merger Consideration, cash in lieu of fractional shares or on any unpaid dividends and distributions payable to holders of Certificates. Until so surrendered, each such Certificate shall, after the Effective Time, represent for all purposes only the right to receive such Merger Consideration. (c) If any portion of the Merger Consideration is to be registered in the name of a Person other than the Person in whose name the applicable surrendered Certificate is registered, it shall be a condition to the registration thereof that the surrendered Certificate shall be properly endorsed or otherwise be in proper form for transfer and that the Person requesting such delivery of the Merger Consideration shall pay to the Exchange Agent any transfer or other similar Taxes required as a result of such registration in the name of a Person other than the registered holder of such Certificate or establish to the satisfaction of the Exchange Agent that such Tax has been paid or is not payable. (d) After the Effective Time, there shall be no further registration of transfers of shares of Burlington Common Stock. If, after the Effective Time, Certificates are presented to the Exchange Agent, the Surviving Corporation or ConocoPhillips, they shall be cancelled and exchanged for the consideration provided for, and in accordance with the procedures set forth, in this Article 3. (e) Any portion of the Exchange Fund that remains unclaimed by the holders of shares of Burlington Common Stock one year after the Effective Time shall be returned to ConocoPhillips, upon demand, and any such holder who has not exchanged his shares of Burlington Common Stock for the Merger Consideration in accordance with this Section 3.5 prior to that time shall thereafter look only to ConocoPhillips for delivery of the Merger Consideration in respect of such holder's shares. Notwithstanding the foregoing, none of Burlington, ConocoPhillips or the Exchange Agent shall be liable to any holder of shares for any Merger Consideration from the Exchange Fund properly delivered to a public official pursuant to applicable abandoned property laws. (f) No dividends or other distributions with respect to shares of ConocoPhillips Common Stock issued in the Merger shall be paid to the holder of any unsurrendered Certificates or Book-Entry Shares until such Certificates or Book-Entry Shares are surrendered as provided in this Section 3.5. Following such surrender, there shall be paid, without interest, to the record holder of the shares of ConocoPhillips Common Stock issued in exchange therefor (i) at the time of such surrender, all dividends and other distributions payable in respect of such shares of ConocoPhillips Common Stock with a record date after the Effective Time and a payment date on or prior to the date of such surrender and not previously paid and (ii) at the appropriate payment date, the dividends or other distributions payable with respect to such shares of ConocoPhillips Common Stock with a record date after the Effective Time but with a payment date subsequent to such surrender. For purposes of dividends or other distributions in respect of shares of ConocoPhillips Common Stock, all shares of ConocoPhillips Common Stock to be issued pursuant to the Merger shall be entitled to dividends pursuant to the immediately preceding sentence as if issued and outstanding as of the Effective Time. (g) Any portion of the Merger Consideration deposited with the Exchange Agent pursuant to Section 3.5 to pay for shares of Burlington Common Stock for which appraisal rights shall have been perfected shall be returned to ConocoPhillips, upon demand. 3.6 Fractional Shares. (a) No fractional shares of ConocoPhillips Common Stock shall be issued in the Merger, but in lieu thereof each holder of shares of Burlington Common Stock otherwise entitled to a fractional share of ConocoPhillips Common Stock will be entitled to receive, from the Exchange Agent in accordance with the provisions of this Section 3.6, a cash payment in lieu of such fractional share of ConocoPhillips Common Stock representing such holder's proportionate interest, if any, in the proceeds from the sale by the Exchange Agent in one or more transactions of shares of ConocoPhillips Common Stock equal to the excess of (x) the aggregate number of shares of ConocoPhillips Common Stock to be delivered to the Exchange Agent by ConocoPhillips pursuant to Section 3.5(a) over (y) the aggregate number of whole shares of ConocoPhillips Common Stock to be distributed to the holders of Certificates pursuant to Section 3.5(b) (such excess being herein called the "Excess Shares"). The parties acknowledge that payment of the cash consideration in lieu of issuing fractional shares was not separately bargained-for consideration but merely represents a mechanical rounding off for purposes of avoiding the expense and inconvenience to ConocoPhillips that would otherwise be caused by the issuance of fractional shares. As soon as practicable after the Effective Time, the Exchange Agent, as agent for the holders of the Certificates representing shares of Burlington Common Stock, shall sell the Excess Shares at then prevailing prices on the NYSE in the manner provided in the following paragraph. (b) The sale of the Excess Shares by the Exchange Agent, as agent for the holders that would otherwise receive fractional shares, shall be executed on the NYSE through one or more member firms of the NYSE and shall be executed in round lots to the extent practicable. Until the proceeds of such sale or sales have been distributed to the holders of shares of Burlington Common Stock, the Exchange Agent shall hold such proceeds in trust for the holders of shares of Burlington Common Stock (the "Common Shares Trust"). The Exchange Agent shall determine the portion of the Common Shares Trust to which each holder of shares of Burlington Common Stock shall be entitled, if any, by multiplying the amount of the aggregate proceeds comprising the Common Shares Trust by a fraction, the numerator of which is the amount of the fractional share interest to which such holder of shares of Burlington Common Stock would otherwise be entitled and the denominator of which is the aggregate amount of fractional share interests to which all holders of shares of Burlington Common Stock would otherwise be entitled. (c) As soon as practicable after the determination of the amount of cash, if any, to be paid to holders of shares of Burlington Common Stock in lieu of any fractional shares of ConocoPhillips Common Stock, the Exchange Agent shall make available such amounts to such holders of shares of Burlington Common Stock without interest, subject to and in accordance with Section 3.5. 3.7 Lost Certificates. If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if required by ConocoPhillips or the Surviving Corporation, the posting by such Person of a bond, in such reasonable amount as the Surviving Corporation may direct, as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Certificate the Merger Consideration to be paid in respect of the shares of Burlington Common Stock represented by such Certificate as contemplated by this Article 3. 3.8 Withholding Rights. Each of the Surviving Corporation and ConocoPhillips shall be entitled to deduct and withhold from the consideration otherwise payable to any Person pursuant to Article 3 such amounts as it is required to deduct and withhold with respect to the making of such payment under any provision of federal, state, local or foreign Tax law. To the extent that amounts are so deducted or withheld by the Surviving Corporation or ConocoPhillips, as the case may be, and paid over to the applicable Governmental Entity, such deducted or withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the shares of Burlington Common Stock or other Person in respect of which such deduction and withholding was made by the Surviving Corporation or ConocoPhillips, as the case may be. 3.9 No Further Ownership Rights in Burlington Common Stock. All shares of ConocoPhillips Common Stock issued and cash paid upon conversion of shares of Burlington Common Stock in accordance with the terms of this Article 3 (including any cash paid pursuant to Section 3.5 or 3.6) shall be deemed to have been issued or paid in full satisfaction of all rights pertaining to the shares of Burlington Common Stock. 3.10 Investment of Cash by the Exchange Agent. The Exchange Agent shall invest any cash included in the Exchange Fund as directed by ConocoPhillips on a daily basis; provided that no such investment or loss thereon shall affect the amounts payable or the timing of the amounts payable to Burlington stockholders pursuant to the other provisions of this Article 3. Any interest and other income resulting from such investments shall promptly be paid to ConocoPhillips. 3.11 Further Assurances. At and after the Effective Time, the officers and directors of the Surviving Corporation shall be authorized to execute and deliver, in the name and on behalf of the Surviving Corporation, Merger Sub or Burlington, any deeds, bills of sale, assignments or assurances and to take and do, in the name and on behalf of the Surviving Corporation, Merger Sub or Burlington, any other actions and things necessary to vest, perfect or confirm of record or otherwise in ConocoPhillips or the Surviving Corporation any and all right, title and interest in, to and under any of the rights, properties or assets acquired or to be acquired by the Surviving Corporation as a result of, or in connection with, the Merger.

No Subsidiary of Burlington owns any shares of Burlington Capital Stock (or any options or other interests convertible into or measured by reference to the value of Burlington Capital Stock).

(ii) Except as set forth in Section 4.1(e)(ii) of the Burlington Disclosure Schedule, the records, systems, controls, data and information of Burlington and its respective Subsidiaries are recorded, stored, maintained and operated under means that are under the exclusive ownership and direct control of Burlington or its Subsidiaries or accountants, except for any non-exclusive ownership and non-direct control that would not reasonably be expected to have a materially adverse effect on the system of internal accounting controls described in the following sentence. Burlington and its Subsidiaries have devised and maintain a system of internal accounting controls sufficient to provide reasonable assurances regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with GAAP, including that: (1) transactions are executed only in accordance with management's authorization; (2) transactions are recorded as necessary to permit preparation of the financial statements of Burlington and its Subsidiaries and to maintain accountability for the assets of Burlington and its Subsidiaries; (3) access to such assets is permitted only in accordance with management's authorization; and (4) the reporting of such assets is compared with existing assets at regular intervals. Each of Burlington and its Subsidiaries (1) has designed disclosure controls and procedures (within the meaning of Rules 13a-15(e) and 15d-15(e) of the Exchange Act) to ensure that material information relating to such entity and its Subsidiaries is made known to the management of such entity (or its general partner) by others within those entities as appropriate to allow timely decisions regarding required disclosure and to make the certifications required by the Exchange Act with respect to the Burlington SEC Documents, and (2) has disclosed, based on its most recent evaluation prior to the date of this Agreement, to its auditors and the audit committee of its Board of Directors (A) any significant deficiencies in the design or operation of internal controls which could adversely affect in any material respect its ability to record, process, summarize and report financial data and have disclosed to its auditors any material weaknesses in internal controls and (B) any fraud, whether or not material, that involves management or other employees who have a significant role in its internal controls. (iii) Since December 31, 2004, through the date hereof, to the knowledge of Burlington, (x) neither Burlington nor any of its Subsidiaries nor any director, officer, employee, auditor, accountant or representative of Burlington or any of its Subsidiaries has received or otherwise had or obtained knowledge of any material complaint, allegation, assertion or claim, whether written or oral, regarding the accounting or auditing practices, procedures, methodologies or methods of Burlington or any of its Subsidiaries or their respective internal accounting controls, including any material complaint, allegation, assertion or claim that Burlington or any of its Subsidiaries has engaged in questionable accounting or auditing practices, and (y) no attorney representing Burlington or any of its Subsidiaries, whether or not employed by Burlington or any of its Subsidiaries, has reported evidence of a material violation of securities laws, breach of fiduciary duty or similar violation by Burlington or any of its officers, directors, employees or agents to the Burlington Board of Directors or any committee thereof or to the General Counsel or Chief Executive Officer of Burlington. (iv) Burlington is in compliance in all material respects with the provisions of the Sarbanes-Oxley Act of 2002 (the "Sarbanes-Oxley Act") that are applicable to Burlington. (f) Absence of Undisclosed Liabilities. Neither Burlington nor any of its Subsidiaries had at September 30, 2005, or has incurred since that date through the date hereof, any liabilities or obligations (whether absolute, accrued, contingent or otherwise) of any nature, except (i) liabilities, obligations or contingencies that (A) are accrued or reserved against in the financial statements in the Burlington September 10-Q or reflected in the notes thereto or (B) were incurred in the ordinary course of business, (ii) liabilities, obligations or contingencies that (A) would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect on Burlington, or (B) have been discharged or paid in full prior to the date hereof, and (iii) liabilities, obligations and contingencies that are of a nature not required to be reflected in the consolidated financial statements of Burlington and its Subsidiaries prepared in accordance with GAAP consistently applied. (g) Absence of Certain Changes or Events. Since September 30, 2005, Burlington has conducted its business only in the ordinary course, and since such date there has not been: (i) any event, change, effect or development that, individually or in the aggregate, has had or would reasonably be expected to have a Material Adverse Effect on Burlington; (ii) prior to the date of this Agreement, any declaration, setting aside or payment of any dividend or other distribution (whether in cash, stock or property) with respect to any Burlington Capital Stock or any repurchase for value by Burlington of any Burlington Capital Stock; (iii) prior to the date of this Agreement, any split, combination or reclassification of any Burlington Capital Stock or any issuance or the authorization of any issuance of any other securities in respect of, in lieu of or in substitution for shares of Burlington Capital Stock; (iv) prior to the date of this Agreement, (A) any granting by Burlington to any director or executive officer of Burlington of any increase in compensation, except in the ordinary course of business consistent with prior practice or as was required under employment agreements included in the Burlington SEC Documents, (B) any granting by Burlington to any such director or executive officer of any increase in severance or termination pay, except as was required under any employment, severance or termination agreements included in the Burlington SEC Documents, or (C) any entry by Burlington into, or any amendment of, any employment, severance or termination agreement with any such director or executive officer; or (v) prior to the date of this Agreement, any change in financial accounting methods, principles or practices by Burlington or any of its Subsidiaries materially affecting the consolidated assets, liabilities or results of operations of Burlington, except insofar as may have been required by a change in GAAP. (h) Legal Proceedings. There is no suit, action or proceeding or investigation pending or, to the knowledge of Burlington, threatened, against or affecting Burlington or any of its Subsidiaries that would, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect on Burlington, nor is there any judgment, decree, injunction, rule or order of any Governmental Entity or arbitrator outstanding against Burlington or its Subsidiaries having, or which would reasonably be expected to have, any such effect. (i) Compliance with Applicable Law.

(c) In furtherance and not in limitation of the covenants of the parties contained in Sections 6.4(a) and 6.4(b) but subject to Section 6.4(b), Burlington and ConocoPhillips, as applicable, shall take all actions necessary to: (i) avoid the entry of, or to have vacated or terminated, any decree, order, or judgment that would restrain, prevent or delay the Closing, on or before the Termination Date, including without limitation defending through litigation on the merits any claim asserted in any court by any Person; and (ii) avoid or eliminate each and every impediment under any Regulatory Law so as to enable the Closing to occur as soon as reasonably possible (and in any event no later than the Termination Date), including, without limitation, (x) proposing, negotiating, committing to and effecting, by consent decree, hold separate order, or otherwise, the sale, divestiture or disposition of such businesses, product lines or assets of ConocoPhillips, Burlington and their respective Subsidiaries and (y) otherwise taking or committing to take actions that after the Closing Date would limit ConocoPhillips or its Subsidiaries' freedom of action with respect to, or its or their ability to retain, one or more of the businesses, product lines or assets of ConocoPhillips, Burlington and their respective Subsidiaries, in each case as may be required in order to avoid the entry of, or to effect the dissolution of, any injunction, temporary restraining order, or other order in any suit or proceeding, which would otherwise have the effect of preventing or materially delaying the Closing. ConocoPhillips and, if requested by ConocoPhillips, Burlington shall agree to divest, sell, dispose of, hold separate, or otherwise take or commit to take any action that limits its freedom of action with respect to, or ConocoPhillips or ConocoPhillips' Subsidiaries' ability to retain, any of the businesses, product lines or assets of ConocoPhillips, Burlington or any of their respective Subsidiaries, provided that any such action is conditioned upon the consummation of the Merger. Burlington agrees and acknowledges that, notwithstanding anything to the contrary in this Section 6.4, in connection with any filing or submission required, action to be taken or commitment to be made by ConocoPhillips, Burlington or any of their respective Subsidiaries to consummate the Merger or other transactions contemplated by this Agreement, neither Burlington nor any of Burlington's Subsidiaries shall, without ConocoPhillips' prior written consent, sell, divest, or dispose of any assets, commit to any sale, divestiture or disposal of businesses, product lines or assets of Burlington and Burlington's Subsidiaries or take any other action or commit to take any action that would limit Burlington's, ConocoPhillips' or any of their respective Subsidiaries' freedom of action with respect to, or their ability to retain any of, their businesses, product lines or assets; provided that the foregoing shall not relieve any party of its obligations under this Agreement. (d) Each party hereto and its respective Board of Directors shall, if any state takeover statute or similar statute becomes applicable to this Agreement, the Merger or any other transactions contemplated hereby, take all action reasonably necessary to ensure that the Merger and the other transactions contemplated by this Agreement may be consummated as promptly as practicable on the terms contemplated hereby and otherwise to minimize the effect of such statute or regulation on this Agreement, the Merger and the other transactions contemplated hereby. 6.5 Acquisition Proposals. (a) Burlington agrees that neither it nor any of its Subsidiaries nor any of the officers and directors of it or its Subsidiaries shall, and that it shall use its reasonable best efforts to cause its and such Subsidiaries' employees, agents and representatives (including any investment banker, attorney or accountant retained by it or any of its Subsidiaries) not to, directly or indirectly, (i) initiate, solicit, encourage or knowingly facilitate any inquiries or the making of any proposal or offer with respect to, or a transaction to effect, a merger, reorganization, share exchange, consolidation, business combination, recapitalization, liquidation, dissolution or similar transaction involving it, or any purchase or sale of 20% or more of the consolidated assets (including stock of its Subsidiaries) of it and its Subsidiaries, taken as a whole, or any purchase or sale of, or tender or exchange offer for, its equity securities that, if consummated, would result in any Person (or the stockholders of such Person) beneficially owning securities representing 20% or more of its total voting power (or of the surviving parent entity in such transaction) (any such proposal, offer or transaction (other than a proposal or offer made by the other party or an affiliate thereof) or announcement of an intention to make any such proposal, offer or transaction, an "Acquisition Proposal"), (ii) have any discussion with or provide any confidential information or data to any Person relating to an Acquisition Proposal, or engage in any negotiations concerning an Acquisition Proposal, or knowingly facilitate any effort or attempt to make or implement an Acquisition Proposal, (iii) approve or recommend, or propose publicly to approve or recommend, any Acquisition Proposal or (iv) approve or recommend, or propose to approve or recommend, or execute or enter into, any letter of intent, agreement in principle, merger agreement, acquisition agreement, option agreement or other similar agreement or propose publicly or agree to do any of the foregoing related to any Acquisition Proposal. (b) Notwithstanding anything in this Agreement to the contrary, Burlington (and its Board of Directors) shall be permitted to (i) comply with applicable law (including Rule 14d-9 and Rule 14e-2 or make any other disclosure required by law or its fiduciary duties (subject, however to clause (B), (C) and (E) of this Section 6.5(b)), (ii) effect a Change in the Burlington Recommendation, or (iii) engage in discussions or negotiations with, or provide any information to, any Person in response to an unsolicited bona fide written Acquisition Proposal by any such Person, if and only to the extent that, in any such case referred to in clause (ii) or (iii) above, (A) the vote at the Burlington Stockholders Meeting on the adoption of this Agreement shall not have been taken, (B) (I) in the case of clause (ii) above, Burlington has received an unsolicited bona fide written Acquisition Proposal from a third party and its Board of Directors concludes in good faith that such Acquisition Proposal constitutes a Superior Proposal and (II) in the case of clause (iii) above, Burlington's Board of Directors concludes in good faith that there is a reasonable likelihood that such Acquisition Proposal would lead to a Superior Proposal, (C) prior to providing any information or data to any Person in connection with an Acquisition Proposal by any such Person, Burlington's Board of Directors receives from such Person an executed confidentiality agreement having provisions that are at least as restrictive as the Confidentiality Agreement, (D) prior to providing any information or data to any Person or entering into discussions or negotiations with any Person, Burlington notifies ConocoPhillips promptly of such inquiries, proposals or offers received by, any such information requested from, or any such discussions or negotiations sought to be initiated or continued with, any of Burlington's representatives indicating, in connection with such notice, the name of such Person and the material terms and conditions of any inquiries, proposals or offers and (E) in the case of clause (ii) above, Burlington has given ConocoPhillips at least three Business Days after delivery of such notice to propose revisions to the terms of this Agreement (or to make another proposal) in response to such Acquisition Proposal and has negotiated in good faith with ConocoPhillips with respect to such proposed revisions or other proposal, if any. Burlington agrees that it will promptly keep ConocoPhillips reasonably informed of the status and terms of any inquiries, proposals or offers and the status and terms of any discussions or negotiations, including the identity of the Person making such inquiry, proposal or offer. Burlington agrees that it will, and will cause its officers, directors and representatives to, immediately cease and cause to be terminated any activities, discussions or negotiations existing as of the date of this Agreement with any Person (other than ConocoPhillips) conducted heretofore with respect to any Acquisition Proposal. Burlington agrees that it will use reasonable best efforts to promptly inform its directors, officers, key employees, agents and representatives of the obligations undertaken in this Section 6.5. Nothing in this Section 6.5 shall (x) permit Burlington to terminate this Agreement (except as specifically provided in paragraph (c) of this Section 6.5 or Article VIII) or (y) affect or limit any other obligation of Burlington under this Agreement). (c) Notwithstanding anything in this Section 6.5 to the contrary, if, at any time prior to the Burlington Stockholder Approval, the Board of Directors of Burlington determines in good faith, after consultation with its financial advisors and outside legal counsel, in response to an Acquisition Proposal that was unsolicited and that did not otherwise result from a breach of this Section 6.5, that such proposal is a Superior Proposal, Burlington may terminate this Agreement; provided, however, that Burlington shall not terminate this Agreement pursuant to this sentence, and any purported termination pursuant to this sentence shall be void and of no force or effect, unless Burlington prior to or concurrently with such termination pursuant to this Section 6.5(c) pays to ConocoPhillips the fee payable pursuant to Section 8.2(b); provided, further, however, that Burlington shall not exercise its right to terminate this Agreement pursuant to this Section 6.5(c) unless Burlington notifies ConocoPhillips that Burlington intends to take such action with respect to an Acquisition Proposal indicating, in connection with such notice, the name of the Person making such Acquisition Proposal and the material terms and conditions of such Acquisition Proposal and Burlington has given ConocoPhillips at least three Business Days after delivery of such notice to propose revisions to the terms of this Agreement (or to make another proposal) in response to such Acquisition Proposal. 6.6 Fees and Expenses. Subject to Section 8.2, whether or not the Merger is consummated, all Expenses incurred in connection with this Agreement and the transactions contemplated hereby shall be paid by the party hereto incurring such Expenses, except (i) Expenses incurred in connection with the filing, printing and mailing of the Proxy Statement/Prospectus and Form S-4 and (ii) Expenses incurred in connection with any consultants that ConocoPhillips and Burlington shall have agreed to retain to assist in obtaining the approvals and clearances under the Antitrust Laws, which, in each case, shall be shared equally by ConocoPhillips and Burlington.

(a) Following the Effective Time, ConocoPhillips and the Surviving Corporation shall (i) jointly and severally indemnify and hold harmless, and provide advancement of Expenses to, all past and present directors, officers and employees of Burlington and its Subsidiaries (in all of their capacities) (A) without limitation to subclause (B) below, to the same extent such individuals are indemnified or have the right to advancement of Expenses as of the date of this Agreement by Burlington pursuant to its Certificate of Incorporation and By-Laws of Burlington and indemnification agreements, if any, in existence on the date hereof with, or for the benefit of, any such individuals and (B) without limitation to subclause (A) above, to the fullest extent permitted by law, in each case for acts or omissions occurring at or prior to the Effective Time (including for acts or omissions occurring in connection with the approval of this Agreement and the consummation of the transactions contemplated hereby) and (ii) include and cause to be maintained in effect in the Certificate of Incorporation and By-Laws of the Surviving Corporation (or any successor to the Surviving Corporation) for a period of six years after the Effective Time, provisions regarding elimination of liability of directors, indemnification of officers, directors and employees and advancement of Expenses that are no less advantageous to the intended beneficiaries than the corresponding provisions contained in the current Certificate of Incorporation and By-Laws of Burlington. Prior to the Effective Time, Burlington shall endeavor to (and if it is unable to, ConocoPhillips shall cause the Surviving Corporation to after the Effective Time) obtain and fully pay (up to a maximum cost of 300% of the current annual premium paid by Burlington for its existing coverage in the aggregate) for "tail" insurance policies (providing only for the Side A coverage for such covered individuals where the existing policies also include coverage for Burlington) with a claims period of at least six years from the Effective Time from an insurance carrier with the same or better credit rating as Burlington's current insurance carrier with respect to directors' and officers' liability insurance in an amount and scope at least as favorable as Burlington's existing policies with respect to matters existing or occurring at or prior to the Effective Time. (b) The obligations of ConocoPhillips and the Surviving Corporation under this Section 6.7 shall not be terminated or modified in such a manner as to adversely affect any indemnitee to whom this Section 6.7 applies without the consent of such affected indemnitee (it being expressly agreed that the indemnitees to whom this Section 6.7 applies shall be third-party beneficiaries of this Section 6.7). 6.8 Employee Benefits. (a) ConocoPhillips agrees that, from and after the Effective Time, ConocoPhillips and its Subsidiaries shall assume and honor all Burlington Benefit Plans in accordance with their terms as in effect immediately before the Effective Time, subject to any permitted amendment or termination thereof. Burlington and ConocoPhillips hereby agree that the consummation of the Merger shall constitute a "Change in Control" for purposes of all Burlington Benefit Plans, pursuant to the terms of such plans in effect on the date hereof. No provision of this Section 6.8(a) shall be construed as a limitation on the right of ConocoPhillips to amend or terminate any Burlington Benefit Plan which Burlington would otherwise have under the terms of such Burlington Benefit Plan, and no provision of this Section 6.8(a) shall be construed to create a right in any employee or beneficiary of such employee under a Burlington Benefit Plan that such employee or beneficiary would not otherwise have under the terms of such plan; provided, however, that ConocoPhillips agrees that it will respect deferrals of salary, bonus or other compensation in place prior to the Effective Time pursuant to the Burlington Benefit Plans. (b) For at least 18 months following the Effective Time, ConocoPhillips shall provide, or cause to be provided, to individuals who are employed by Burlington or any of its Subsidiaries immediately prior to the Effective Time (other than any such employees whose terms of employment are governed by a collective bargaining agreement) who remain employed with ConocoPhillips or any Subsidiary of ConocoPhillips (the "Burlington Employees"), for so long as such Burlington Employees remain so employed, compensation (it being understood that discretionary incentive and equity-based awards will remain discretionary) and employee benefits (i) pursuant to Burlington's or Burlington's Subsidiaries' compensation and employee benefit plans, programs, policies and arrangements as provided to such employees immediately prior to the Effective Time or (ii) pursuant to compensation and employee benefit plans, programs, policies or arrangements maintained by ConocoPhillips or any Subsidiary of ConocoPhillips providing coverage and benefits, which, in the aggregate, are no less favorable than those provided pursuant to Burlington's and Burlington's Subsidiaries' plans, programs, policies and arrangements to such employees immediately prior to the Effective Time. (c) For all purposes under the employee benefit plans of ConocoPhillips and its Subsidiaries providing benefits to any Burlington Employees after the Effective Time (the "New Plans"), ConocoPhillips will, or will cause its Subsidiaries to, give Burlington Employees full credit with his or her years of service for purposes of eligibility, vesting and benefit accrual (excluding benefit accrual under any defined benefit pension plans) under any employee benefit plans or arrangements maintained by ConocoPhillips or any of its Subsidiaries for such Burlington employee's service with Burlington or any Burlington Subsidiary to the same extent recognized by Burlington immediately prior to the Effective Time. In addition, and without limiting the generality of the foregoing: (i) each Burlington Employee shall be immediately eligible to participate, without any waiting time, in any and all New Plans to the extent coverage under such New Plan replaces coverage under a Burlington Benefit Plan in which such Burlington Employee participated immediately before the Effective Time (such plans, collectively, the "Old Plans"); and (ii) for purposes of each New Plan providing medical, dental, pharmaceutical and/or vision benefits to any Burlington Employee, ConocoPhillips shall cause all pre-existing condition exclusions and actively-at-work requirements of such New Plan to be waived for such employee and his or her covered dependents, and ConocoPhillips shall cause any eligible expenses incurred by such 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 taken into account under such New Plan for purposes of satisfying all deductible, coinsurance and maximum out-of-pocket requirements applicable to such 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. (d) Without limiting the generality of this Section 6.8, ConocoPhillips and Burlington agree to the employee matters set forth in Section 6.8(d) of the Burlington Disclosure Schedule. 6.9 Public Announcements. ConocoPhillips and Burlington shall, unless otherwise required by applicable law or by obligations pursuant to any listing agreement with or rules of any securities exchange, consult with the other party before issuing, and provide the other party the opportunity to review and comment upon, any press release or, to the extent practical, otherwise making any public statement with respect to this Agreement or the transactions contemplated hereby. In addition to the foregoing, except as required by applicable law and to the extent disclosed in or consistent with the Proxy Statement/Prospectus in accordance with the provisions of Section 6.1, neither ConocoPhillips nor Burlington shall issue any press release or otherwise make any public statement or disclosure concerning the other party or the other party's business, financial condition or results of operations without the consent of the other party, which consent shall not be unreasonably withheld or delayed. 6.10 Listing of Shares of ConocoPhillips Common Stock. ConocoPhillips shall cause the shares of ConocoPhillips Common Stock to be issued in the Merger and the shares of ConocoPhillips Common Stock to be reserved for issuance upon exercise of the Burlington Stock Options, to be approved for listing on the NYSE, subject to official notice of issuance, prior to the Closing Date. 6.11 Rights Agreement. The Board of Directors of ConocoPhillips shall take all action to the extent necessary (including amending the ConocoPhillips Rights Agreement) in order to render the ConocoPhillips Rights inapplicable to the Merger and the other transactions contemplated by this Agreement. The Board of Directors of Burlington shall take all action to the extent necessary (including amending the Burlington Rights Agreement) in order to render the Burlington Rights inapplicable to the Merger and the other transactions contemplated by this Agreement. 6.12 Affiliates.

After the date of this Agreement, each of ConocoPhillips and Burlington shall coordinate with the other the declaration of any dividends in respect of ConocoPhillips Common Stock and Burlington Common Stock and the record dates and payment dates relating thereto, it being the intention of the parties hereto that holders of Burlington Common Stock shall not receive two dividends, or fail to receive one dividend, for any quarter, including the quarter in which the Effective Time occurs, with respect to their shares of Burlington Common Stock and shares of ConocoPhillips Common Stock any such holder receives in exchange therefor in the Merger. 6.15 Tax Representation Letters.

The parties hereto agree that any remedy or amount payable pursuant to this Section 8.2 shall not preclude any other remedy or amount payable hereunder, and shall not be an exclusive remedy, for any willful and material breach of any representation, warranty, covenant or agreement contained in this Agreement. 8.3 Amendment. This Agreement may be amended by the parties hereto, by action taken or authorized by their respective Boards of Directors, at any time before or after the Burlington Stockholder Approval, but, after any such approval, no amendment shall be made which by law or in accordance with the rules of any relevant stock exchange requires further approval by such stockholders without such further approval. This Agreement may not be amended, except by an instrument in writing signed on behalf of each of the parties hereto. 8.4 Extension; Waiver. At any time prior to the Effective Time, the parties hereto, by action taken or authorized by their respective Boards of Directors, may, to the extent legally allowed, (a) extend the time for the performance of any of the obligations or other acts of the other parties hereto, (b) waive any inaccuracies in the representations and warranties contained herein or in any document delivered pursuant hereto and (c) waive compliance with any of the agreements or conditions contained herein. Any agreement on the part of a party hereto to any such extension or waiver shall be valid only if set forth in a written instrument signed on behalf of such party hereto. The failure of any party hereto to assert any of its rights under this Agreement or otherwise shall not constitute a waiver of those rights. ARTICLE IX GENERAL PROVISIONS 9.1 Non-Survival of Representations, Warranties and Agreements. None of the representations, warranties, covenants and other agreements in this Agreement or in any instrument delivered pursuant to this Agreement, including any rights arising out of any breach of such representations, warranties, covenants, agreements and other provisions, shall survive the Effective Time, except for those covenants, agreements and other provisions contained herein that by their terms apply or are to be performed in whole or in part after the Effective Time and this Article IX (including without limitation Section 6.7). 9.2 Notices.

(a) When a reference is made in this Agreement to Articles, Sections, Exhibits or Schedules, such reference shall be to an Article or Section of or Exhibit or Schedule to this Agreement unless otherwise indicated. The table of contents and headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement. Whenever the words "include," "includes" or "including" are used in this Agreement, they shall be deemed to be followed by the words "without limitation". The words "hereby," "herein," "hereof" or "hereunder," and similar terms are to be deemed to refer to this Agreement as a whole and not to any specific section. In addition, each Section of this Agreement is qualified by the matters set forth in the related Section of the ConocoPhillips Disclosure Schedule and the Burlington Disclosure Schedule, as the case may be, and by such matters set forth any place else in this Agreement or in the ConocoPhillips Disclosure Schedule or the Burlington Disclosure Schedule where the applicability of such qualification to the Section of this Agreement is reasonably apparent. (b) The parties have participated jointly in negotiating and drafting this Agreement. In the event that an ambiguity or a question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the parties, and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any provision of this Agreement. 9.4 Counterparts. This Agreement may be executed by facsimile and in one or more counterparts, all of which shall be considered one and the same agreement and shall become effective when one or more counterparts have been signed by each of the parties and delivered to the other parties, it being understood that all parties hereto need not sign the same counterpart. 9.5 Entire Agreement; No Third Party Beneficiaries. (a) This Agreement, the Confidentiality Agreement and the Exhibits and disclosure schedules and the other agreements and instruments of the parties hereto delivered in connection herewith constitute the entire agreement and supersede all prior agreements and understandings, both written and oral, among the parties hereto with respect to the subject matter hereof. (b) This Agreement shall be binding upon and inure solely to the benefit of each party hereto, and nothing in this Agreement, express or implied, is intended to or shall confer upon any other Person any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement, other than Section 6.7 (which is intended to be for the benefit of the Persons covered thereby). 9.6 Governing Law. This Agreement shall be governed and construed in accordance with the laws of the State of Delaware (without giving effect to choice of law principles thereof). 9.7 Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any law or public policy, all other terms and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party hereto. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties hereto as closely as possible in an acceptable manner in order that the transactions contemplated hereby are consummated as originally contemplated to the greatest extent possible. 9.8 Assignment. Neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned by any of the parties hereto, in whole or in part (whether by operation of law or otherwise), without the prior written consent of the other parties hereto, and any attempt to make any such assignment without such consent shall be null and void. Subject to the preceding sentence, this Agreement will be binding upon, inure to the benefit of and be enforceable by the parties hereto and their respective successors and assigns. 9.9 Submission to Jurisdiction; Waivers. Each of ConocoPhillips and Burlington irrevocably agrees that any legal action or proceeding with respect to this Agreement or for recognition and enforcement of any judgment in respect hereof brought by the other party hereto or its successors or assigns shall be brought and determined exclusively in the Court of Chancery or other courts of the State of Delaware, and each of ConocoPhillips and Burlington hereby irrevocably submits with regard to any such action or proceeding for itself and in respect to its property, generally and unconditionally, to the exclusive jurisdiction of the aforesaid courts (and, to the fullest extent permitted by law, to the Court of Chancery) and to accept service of process in any manner permitted by such courts. Each of ConocoPhillips and Burlington 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, (a) any claim that it is not personally subject to the jurisdiction of the above-named courts for any reason other than the failure to lawfully serve process, (b) 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), (c) to the fullest extent permitted by applicable law, that (i) the suit, action or proceeding in any such court is brought in an inconvenient forum, (ii) the venue of such suit, action or proceeding is improper and (iii) this Agreement, or the subject matter hereof, may not be enforced in or by such courts and (d) any right to a trial by jury. 9.10 Enforcement. The parties hereto agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms.
