(b) ConocoPhillips shall determine the allocations described in Section 2.08(a), the Federal Income Taxes or State Income Taxes, as applicable (or Tax Benefits or reductions in Tax Benefits, as applicable) and any Other Taxes, as applicable, attributable to, or arising with respect to or as a result of, assets or activities of the ▇▇▇▇▇▇▇▇ 66 Business or the ConocoPhillips Business, the utilization of foreign tax credits under Section 901 by the ▇▇▇▇▇▇▇▇ 66 Business and the Taxes (or reductions in Tax Benefits) that would not have arisen but for the utilization of foreign tax credits by the ▇▇▇▇▇▇▇▇ 66 Business. In connection with any relevant demand for payment under Section 5, ConocoPhillips shall provide ▇▇▇▇▇▇▇▇ 66 with written notice containing a reasonably detailed summary of any such relevant determinations and timely respond to any reasonable requests from ▇▇▇▇▇▇▇▇ 66 for additional information with respect to any such determinations. Notwithstanding anything to the contrary in this Agreement, such determinations by ConocoPhillips shall, in the absence of bad faith or clear error, be conclusive.

Section 2.09 Deductible and Includible Tax Payments. Notwithstanding any other provision in this Agreement, without duplication for any amounts otherwise required to be paid hereunder (and provided that, for the absence of doubt, this Section 2.09 shall not apply to payments required to be made pursuant to Paragraph 2 of Schedule 2.05), (a) in the event that any Company (the “Benefit Intercompany Payor”) is required to pay over a Tax Benefit to the other Company (the “Benefit Intercompany Payee”) hereunder, (i) the Benefit Intercompany Payor shall also pay over to the Benefit Intercompany Payee any interest relating thereto that is

received (by way of offset or otherwise) by the Benefit Intercompany Payor or any of its Affiliates from the applicable Tax Authority and (ii) the Benefit Intercompany Payee shall be required to pay to the Benefit Intercompany Payor the amount of any Tax (or any reduction in Tax Benefit) actually suffered in cash by the Benefit Intercompany Payor or any of its Affiliates resulting (on a “with and without” basis) from the receipt by the Benefit Intercompany Payor or any of its Affiliates of the Tax Benefit from the applicable Tax Authority and (b) in the event that any Company (the “Tax Intercompany Payor”) is required to pay the other Company (the “Tax Intercompany Payee”) hereunder in respect of a Tax (or reduction in any Tax Benefit), (i) for the absence of doubt, the Tax Intercompany Payor shall pay to the Tax Intercompany Payee any interest or penalties relating thereto that is required to be paid (by way of offset or otherwise) by the Tax Intercompany Payee or any of its Affiliates to the applicable Tax Authority and (ii) the Tax Intercompany Payee shall be required to pay to the Tax Intercompany Payor the amount of any Tax Benefit actually realized in cash by the Tax Intercompany Payee or any of its Affiliates resulting (on a “with and without” basis) from the payment by the Tax Intercompany Payee or any of its Affiliates of the Tax to the applicable Tax Authority (or the reduction in Tax Benefit). Any amounts required to be paid pursuant to this Section 2.09 shall be calculated or recalculated, as applicable, in light of any Final Determination or any other facts that may arise or come to light after a payment is made pursuant to this Section 2.09 that would affect any amount required to be paid pursuant to this Section 2.09, and an appropriate adjusting payment shall be made (without duplication) by ▇▇▇▇▇▇▇▇ 66 or ConocoPhillips, as applicable, such that the aggregate amounts paid pursuant to this Section 2.09 reflect such recalculated amount.

Section 3. Proration of Taxes for Straddle Periods.

(a) General Method of Proration. In the case of any Straddle Period, Tax Items shall be apportioned between Pre-Distribution Periods and Post-Distribution Periods in accordance with the principles of Treasury Regulation Section 1.1502-76(b) as reasonably interpreted and applied by the Companies. No election shall be made under Treasury Regulation Section 1.1502-76(b)(2)(ii) (relating to ratable allocation of a year’s Tax Items). If the Distribution Date is not an Accounting Cutoff Date, the provisions of Treasury Regulation Section 1.1502-76(b)(2)(iii) will be applied to ratably allocate the Tax Items (other than extraordinary items) for the month which includes the Distribution Date.

(b) Transaction Treated as Extraordinary Item. In determining the apportionment of Tax Items between Pre-Distribution Periods and Post-Distribution Periods, any Tax Items relating to the Transactions shall be treated as extraordinary items described in Treasury Regulation Section 1.1502-76(b)(2)(ii)(C) and shall (to the extent occurring on or prior to the Distribution Date) be allocated to Pre-Distribution Periods, and any Taxes related to such items shall be treated under Treasury Regulation Section 1.1502-76(b)(2)(iv) as relating to such extraordinary item and shall (to the extent occurring on or prior to the Distribution Date) be allocated to Pre-Distribution Periods.

Section 4. Preparation and Filing of Tax Returns.

(c) ConocoPhillips Separate Returns which ConocoPhillips reasonably determines are required to be filed by the Companies or any of their Affiliates for Tax Periods ending on, before or after the Distribution Date.

For the absence of doubt, the Tax Returns required to be prepared and filed by ▇▇▇▇▇▇▇▇ 66 under this Section 4.03 shall include (a) any ▇▇▇▇▇▇▇▇ 66 Federal Consolidated Income Tax Return for Tax Periods ending after the Distribution Date and (b) ▇▇▇▇▇▇▇▇ 66 Separate Returns required to be filed for Tax Periods ending on, before or after the Distribution Date.

Section 4.04 Tax Return Filing and Past Practices.

(a) General Rule. Except as provided in Section 4.04(b), with respect to any Tax Return that ▇▇▇▇▇▇▇▇ 66 has the obligation and right to prepare and file, or cause to be prepared and filed, under Section 4.03, to the extent Tax Items reported on such Tax Return might reasonably be expected to affect Taxes (or rights to Tax Benefits) for which ConocoPhillips is responsible (or to which ConocoPhillips is entitled) under this Agreement, such Tax Return shall, in the case of a Tax Return that is not a UK Tax Return, be prepared in accordance with the past practice of the ConocoPhillips Group in determining accrued assets and liabilities for cash taxes on the books and records of ConocoPhillips and its subsidiaries and the past return filing practice of the ConocoPhillips Group with respect to the relevant Tax Return (including any past accounting methods, elections and conventions) (the “ConocoPhillips Past Practice”) and, in the case of a UK Tax Return, on a basis which is consistent with the basis on which UK Tax Documents already submitted by or on behalf of the relevant taxpayer to HM Revenue & Customs were prepared and filed (the “ConocoPhillips UK Tax Practice”), unless (i) any Tax Items with respect to the Tax Returns in question are not covered by the ConocoPhillips Past Practice or the

ConocoPhillips UK Tax Practice (as relevant) (in which case, with respect to such Tax Items, such Tax Returns shall be prepared in accordance with reasonable Tax accounting practices selected by ConocoPhillips), (ii) no Substantial Authority exists for the ConocoPhillips Past Practice or the ConocoPhillips UK Tax Practice (as relevant) with respect to any Tax Items reportable on the Tax Returns in question (in which case, with respect to such Tax Items, such Tax Returns shall be prepared in accordance with reasonable Tax accounting practices selected by ConocoPhillips), or (iii) there is no adverse effect to ConocoPhillips (in which case, the Tax Returns in question shall be prepared in accordance with reasonable Tax accounting practices selected by ▇▇▇▇▇▇▇▇ 66).

(b) Reporting of Transactions. The Tax treatment of the Transactions reported on any Tax Return shall be consistent with the treatment thereof in the Ruling Requests and the Tax Opinions/Rulings, unless there is no reasonable basis for such Tax treatment. To the extent there is a Tax treatment relating to the Transactions which is not covered by the Ruling Requests or the Tax Opinions/Rulings, the Tax treatment of the Transactions reported on any Tax Return for which ▇▇▇▇▇▇▇▇ 66 is the Responsible Party shall be consistent with that on any Tax Return filed or to be filed by ConocoPhillips or any member of the ConocoPhillips Group or caused or to be caused to be filed by ConocoPhillips (“ConocoPhillips Group Transaction Returns”), unless there is no reasonable basis for such Tax treatment. To the extent there is a Tax treatment relating to the Transactions which is not covered by the Ruling Requests, the Tax Opinions/Rulings or ConocoPhillips Group Transaction Returns, the Companies shall agree on the Tax treatment to be reported on any Tax Return. For this purpose, the Tax treatment shall be determined by ConocoPhillips and shall be agreed to by ▇▇▇▇▇▇▇▇ 66 unless either (i) no Substantial Authority exists for the technical merits of the position, or (ii) such Tax treatment is inconsistent with the Tax treatment contemplated in the Ruling Requests, the Tax Opinions/Rulings and/or the ConocoPhillips Group Transaction Returns. Any dispute regarding such Tax treatment shall be referred for resolution pursuant to Section 12, sufficiently in advance of the filing date of such Tax Return (including extensions) to permit timely filing of the Tax Return.

Section 4.05 Consolidated or Combined Tax Returns. ▇▇▇▇▇▇▇▇ 66 will elect and join, and will cause its respective Affiliates to elect and join, in filing any ConocoPhillips State Combined Income Tax Returns and any Joint Returns that ConocoPhillips determines are required to be filed or that ConocoPhillips chooses to file pursuant to Section 4.02(b).

Section 4.06 Right to Review Tax Returns.

(a) ConocoPhillips Federal Consolidated Income Tax Returns and ConocoPhillips State Combined Income Tax Returns. ConocoPhillips shall make any ConocoPhillips Federal Consolidated Income Tax Return and ConocoPhillips State Combined Income Tax Return (other than any such Tax Return for which ▇▇▇▇▇▇▇▇ 66 is the Responsible Company) and any workpapers related to any such Tax Return available for review by ▇▇▇▇▇▇▇▇ 66, if requested by ▇▇▇▇▇▇▇▇ 66. ConocoPhillips shall use its reasonable best efforts to make such Tax Return available to ▇▇▇▇▇▇▇▇ 66 for review and comment as required under this paragraph prior to the due date (including extensions) for filing of such Tax Return. ▇▇▇▇▇▇▇▇ 66 shall use reasonable best efforts to respond in writing to ConocoPhillips with any comments no later than the date on which ConocoPhillips files such Tax Return with the applicable Tax Authority, provided, however that ▇▇▇▇▇▇▇▇ 66’s comments shall be limited to the reporting of any material Tax Item

on such Tax Return with respect to which ▇▇▇▇▇▇▇▇ 66 reasonably believes that no Substantial Authority exists for the technical merits of the position. ConocoPhillips shall reasonably consider such comments with respect to the reporting of any such material Tax Item on such Return (including considering whether to revise the reporting of such Tax Item on such Tax Return prior to filing such Tax Return with the applicable Tax Authority, file an amended Tax Return with the applicable Tax Authority revising the reporting of such Tax Item, or pursue an adjustment to the reporting of such Tax Item in connection with a Tax Contest with respect to such Tax Return or make no change).

(b) Certain Other Joint Returns and Separate Returns. The Responsible Company with respect to any material Joint Return (other than any ConocoPhillips Consolidated Federal Income Tax Return or any ConocoPhillips State Combined Income Tax Return for which ConocoPhillips is the Responsible Company) or material Separate Return shall make such Tax Return and related workpapers available for review by the other Company, if requested by the other Company, to the extent (i) such Tax Return relates to Taxes for which the requesting party would reasonably be expected to be liable under applicable Tax Law or responsible under this Agreement, (ii) such Tax Return relates to Taxes and the requesting party would reasonably be expected to be liable under applicable Tax Law or responsible under this Agreement in whole or in part for any additional Taxes owing as a result of adjustments to the amount of such Taxes reported on such Tax Return, (iii) such Tax Return relates to Taxes for which the requesting party would reasonably be expected to have a claim for Tax Benefits under this Agreement, (iv) the requesting party reasonably determines that it must inspect such Tax Return to confirm compliance with the terms of this Agreement, (v) such Tax Return relates to an Agreed UK Group Relief Surrender, or (vi) such Tax Return relates to a Transfer Pricing Adjustment relating to a transaction or transactions involving a member of the requesting party’s Group. The Responsible Company shall use its reasonable best efforts to make such Tax Return available for review and comment as required under this paragraph prior to the due date (including extensions) for filing of such Tax Return. The requesting party shall use reasonable best efforts to respond in writing to the Responsible Party with any comments no later than the date on which the Responsible Party files such Tax Return with the applicable Tax Authority provided, however that (x) if ConocoPhillips is the Responsible Company, ▇▇▇▇▇▇▇▇ 66’s comments shall be limited to the reporting of any material Tax Item on such Tax Return with respect to which ▇▇▇▇▇▇▇▇ 66 reasonably believes that no Substantial Authority exists for the technical merits of the position and (y) if ▇▇▇▇▇▇▇▇ 66 is the Responsible Company, ConocoPhillips’ comments shall be limited to the reporting of any material Tax Item on such Tax Return with respect to which ConocoPhillips reasonably believes that no Substantial Authority exists for the technical merits of the position or the reporting of any Tax Item on such Tax Return in accordance with this Agreement or the ConocoPhillips Past Practice or ConocoPhillips UK Tax Practice, as applicable. The Responsible Party shall reasonably consider such comments with respect to the reporting of any such material Tax Item on such Return (including considering whether to revise the reporting of such Tax Item on such Tax Return prior to filing such Tax Return with the applicable Tax Authority, file an amended Tax Return with the applicable Tax Authority revising the reporting of such Tax Item, or pursue an adjustment to the reporting of such Tax Item in connection with a Tax Contest with respect to such Tax Return or make no change).

(c) Execution of Returns Prepared by Other Party. In the case of any Tax Return which is required to be prepared and filed by one Company under this Agreement and which is required by Law to be signed by the other Company or its Affiliate (or by an authorized representative thereof), the Company which is legally required to sign such Tax Return (or whose Affiliate is legally required to sign or an authorized representative thereof) shall not be required to sign such Tax Return under this Agreement if there is no reasonable basis for the Tax treatment of any Tax Item reported on the Tax Return or the Tax treatment of any Tax Item reported on the Tax Return should, in the opinion of a Tax advisor from a nationally recognized legal, accounting or professional tax services firm, subject the other Company or its Affiliate (or its authorized representatives) to material penalties.

Section 4.07 ▇▇▇▇▇▇▇▇ 66 Carrybacks and Claims for Refund. ▇▇▇▇▇▇▇▇ 66 hereby agrees that, unless ConocoPhillips consents in writing, (a) no Adjustment Request with respect to any Joint Return shall be filed, and (b) any available elections to waive the right to claim in any Pre-Distribution Period with respect to any Joint Return any ▇▇▇▇▇▇▇▇ 66 Carryback arising in a Post-Distribution Period shall be made, and no affirmative election shall be made to claim any such ▇▇▇▇▇▇▇▇ 66 Carryback; provided, however, that the parties agree that any such Adjustment Request shall be made with respect to any ▇▇▇▇▇▇▇▇ 66 Carryback related to Federal Taxes or State Taxes, as applicable, upon the reasonable request of ▇▇▇▇▇▇▇▇ 66, if such ▇▇▇▇▇▇▇▇ 66 Carryback is necessary to prevent the loss of the Federal and/or State Tax Benefit of such ▇▇▇▇▇▇▇▇ 66 Carryback (including, but not limited to, an Adjustment Request with respect to a ▇▇▇▇▇▇▇▇ 66 Carryback of a capital loss for Federal and/or State Tax purposes arising in a Post-Distribution Period to a Pre-Distribution Period) and such Adjustment Request, based on ConocoPhillips’ sole, reasonable determination, will cause no Tax detriment to ConocoPhillips, the ConocoPhillips Group or any member of the ConocoPhillips Group. Any Adjustment Request which ConocoPhillips consents to make under this Section 4.07 shall be prepared and filed by the Responsible Company for the Joint Return to be adjusted.

Section 4.08 Apportionment of Earnings and Profits and Tax Attributes. ConocoPhillips shall in good faith advise ▇▇▇▇▇▇▇▇ 66 in writing of the portion, if any, of any earnings and profits, Tax Attribute, overall foreign loss or other consolidated, combined or unitary attribute which ConocoPhillips determines shall be allocated or apportioned to the ▇▇▇▇▇▇▇▇ 66 Group under applicable Law. ▇▇▇▇▇▇▇▇ 66 and all members of the ▇▇▇▇▇▇▇▇ 66 Group shall prepare all Tax Returns in accordance with such written notice. In the event that any temporary or final amendments to Treasury Regulations are promulgated after the date of this Agreement that provide for any election to apply such regulations retroactively, then any such election shall be made only to the extent that ConocoPhillips determines to make such election. As soon as practicable after receipt of a written request from ▇▇▇▇▇▇▇▇ 66, ConocoPhillips shall provide copies of any studies, reports, and workpapers supporting the earnings and profits and other Tax Attributes allocable to ▇▇▇▇▇▇▇▇ 66. In the event of a subsequent adjustment to the earnings and profits or any Tax Attributes determined by ConocoPhillips, ConocoPhillips shall promptly notify ▇▇▇▇▇▇▇▇ 66 in writing of such adjustment. For the absence of doubt, ConocoPhillips shall not be liable to ▇▇▇▇▇▇▇▇ 66 or any member of the ▇▇▇▇▇▇▇▇ 66 Group for any failure of any determination under this Section 4.08 to be accurate under applicable Law.

(f) ▇▇▇▇▇▇▇▇ 66 Restructuring. ▇▇▇▇▇▇▇▇ 66 and ▇▇▇▇▇▇▇▇ 66 Company shall not engage in, cause or permit any internal restructuring (including by making or revoking any election under Treasury Regulation Section 301.7701-3) involving ▇▇▇▇▇▇▇▇ 66 or ▇▇▇▇▇▇▇▇ 66 Company and/or any of their subsidiaries or any contribution, sale or other transfer of any of the assets directly or indirectly transferred to ▇▇▇▇▇▇▇▇ 66 as part of the Contribution, transferred to ▇▇▇▇▇▇▇▇ 66 Company as part of the Internal Contribution, or otherwise transferred to ▇▇▇▇▇▇▇▇ 66 or ▇▇▇▇▇▇▇▇ 66 Company, as applicable, or any of their subsidiaries in connection with the Transaction (any such action, a “▇▇▇▇▇▇▇▇ 66 Restructuring”) during or with respect to any Tax Period (or portion thereof) ending on or prior to 6 months following the Distribution Date without obtaining the prior written consent of ConocoPhillips (such prior written consent not to be unreasonably withheld). ▇▇▇▇▇▇▇▇ 66 or ▇▇▇▇▇▇▇▇ 66 Company, as applicable, shall provide written notice to ConocoPhillips describing any ▇▇▇▇▇▇▇▇ 66 Restructuring proposed to be taken during or with respect to any Tax Period (or portion thereof) ending on or prior to 6 months following the Distribution Date and shall consult with ConocoPhillips regarding any such proposed actions.

(g) Distributions by Foreign ▇▇▇▇▇▇▇▇ 66 Subsidiaries. Until January 1^st of the calendar year immediately following the calendar year in which the Distribution occurs, ▇▇▇▇▇▇▇▇ 66 shall neither cause nor permit any foreign subsidiary of ▇▇▇▇▇▇▇▇ 66 to enter into any transaction or take any action that would be considered under the Code to constitute the declaration or payment of a dividend (including pursuant to Section 304 of the Code) without obtaining the prior written consent of ConocoPhillips (such prior written consent not to be unreasonably withheld).

Section 6.03 Procedures Regarding Opinions and Rulings.

(a) If ▇▇▇▇▇▇▇▇ 66 notifies ConocoPhillips that it desires to take one of the actions described in clauses (i) through (vi) of Section 6.02(d) (a “Notified Action”), ConocoPhillips and ▇▇▇▇▇▇▇▇ 66 shall reasonably cooperate to attempt to obtain the Ruling or Unqualified Tax Opinion referred to in Section 6.02(d), unless ConocoPhillips shall have waived the requirement to obtain such Ruling or Unqualified Tax Opinion.

(b) Rulings or Unqualified Tax Opinions at ▇▇▇▇▇▇▇▇ 66’s Request. ConocoPhillips agrees that at the reasonable request of ▇▇▇▇▇▇▇▇ 66 pursuant to Section 6.02(d), ConocoPhillips shall cooperate with ▇▇▇▇▇▇▇▇ 66 and use its reasonable best efforts to seek to obtain, as expeditiously as possible, a Ruling from the IRS or an Unqualified Tax Opinion for the purpose of permitting ▇▇▇▇▇▇▇▇ 66 to take the Notified Action. Further, in no event shall ConocoPhillips be required to file any Ruling Request under this Section 6.03(b) unless ▇▇▇▇▇▇▇▇ 66 represents that (i) it has read the Ruling Request, and (ii) all information and representations, if any, relating to any member of the ▇▇▇▇▇▇▇▇ 66 Group, contained in the Ruling Request documents are (subject to any qualifications therein) true, correct and complete. ▇▇▇▇▇▇▇▇ 66 shall reimburse ConocoPhillips for all reasonable costs and expenses incurred by the ConocoPhillips Group in obtaining a Ruling or Unqualified Tax Opinion requested by ▇▇▇▇▇▇▇▇ 66 within ten Business Days after receiving an invoice from ConocoPhillips therefor.

(c) Rulings or Unqualified Tax Opinions at ConocoPhillips’ Request. ConocoPhillips shall have the right to obtain a Ruling or an Unqualified Tax Opinion at any time in its sole and absolute discretion. If ConocoPhillips determines to obtain a Ruling or an Unqualified Tax Opinion, ▇▇▇▇▇▇▇▇ 66 shall (and shall cause each Affiliate of ▇▇▇▇▇▇▇▇ 66 to) cooperate with ConocoPhillips and take any and all actions reasonably requested by ConocoPhillips in connection with obtaining the Ruling or Unqualified Tax Opinion (including, without limitation, by making any representation or covenant or providing any materials or information requested by the IRS or Tax Advisor; provided that ▇▇▇▇▇▇▇▇ 66 shall not be required to make (or cause any Affiliate of ▇▇▇▇▇▇▇▇ 66 to make) any representation or covenant that is inconsistent with historical facts or as to future matters or events over which it has no control). ConocoPhillips and ▇▇▇▇▇▇▇▇ 66 shall each bear its own costs and expenses in obtaining a Ruling or an Unqualified Tax Opinion requested by ConocoPhillips.

(d) ▇▇▇▇▇▇▇▇ 66 hereby agrees that ConocoPhillips shall have sole and exclusive control over the process of obtaining any Ruling, and that only ConocoPhillips shall apply for a Ruling.

with a final copy; and (iii) ConocoPhillips shall provide ▇▇▇▇▇▇▇▇ 66 with notice reasonably in advance of, and ▇▇▇▇▇▇▇▇ 66 shall have the right to attend, any formally scheduled meetings with the IRS (subject to the approval of the IRS) that relate to such Ruling. Neither ▇▇▇▇▇▇▇▇ 66 nor any ▇▇▇▇▇▇▇▇ 66 Affiliate directly or indirectly controlled by ▇▇▇▇▇▇▇▇ 66 shall seek any guidance from the IRS or any other Tax Authority (whether written, verbal or otherwise) at any time concerning the Contribution, the Distribution, the Internal Contribution, the Internal Distribution (including the impact of any transaction on the Contribution, the Distribution, the Internal Contribution or the Internal Distribution) or any transaction referred to in Section 6.02(a)(ii).

Section 6.04 Liability for Tax-Related Losses.

(a) Notwithstanding anything in this Agreement, the Separation and Distribution Agreement, the Indemnification and Release Agreement, or any other Ancillary Agreement to the contrary, subject to Section 6.04(b), ▇▇▇▇▇▇▇▇ 66 shall be responsible for, and shall indemnify and hold harmless ConocoPhillips, ConocoPhillips Company, each of their Affiliates and each of their respective officers, directors and employees from and against, one hundred percent (100%) of any Tax-Related Losses that are attributable to or result from any one or more of the following: (i) the acquisition (other than pursuant to the Internal Contribution, the Internal Distribution, the Contribution, or the Distribution) of all or a portion of the stock and/or assets of ▇▇▇▇▇▇▇▇ 66 and/or its subsidiaries by any means whatsoever by any Person, (ii) any negotiations, understandings, agreements or arrangements by ▇▇▇▇▇▇▇▇ 66 with respect to transactions or events (including, without limitation, stock issuances, pursuant to the exercise of stock options or otherwise, option grants, capital contributions or acquisitions, or a series of such transactions or events) that cause the Internal Distribution or the Distribution to be treated as part of a plan pursuant to which one or more Persons acquire directly or indirectly stock of ▇▇▇▇▇▇▇▇ 66 Company or ▇▇▇▇▇▇▇▇ 66, as applicable, representing a Fifty-Percent or Greater Interest therein, (iii) any action or failure to act by ▇▇▇▇▇▇▇▇ 66 after the Distribution (including, without limitation, any amendment to ▇▇▇▇▇▇▇▇ 66’s certificate of incorporation (or other organizational documents), whether through a stockholder vote or otherwise) affecting the voting rights of ▇▇▇▇▇▇▇▇ 66 stock or ▇▇▇▇▇▇▇▇ 66 Company stock (including, without limitation, through the conversion of one class of ▇▇▇▇▇▇▇▇ 66 Capital Stock or ▇▇▇▇▇▇▇▇ 66 Company Capital Stock, respectively, into another class of ▇▇▇▇▇▇▇▇ 66 Capital Stock or ▇▇▇▇▇▇▇▇ 66 Company Capital Stock, respectively), (iv) any act or failure to act by ▇▇▇▇▇▇▇▇ 66, ▇▇▇▇▇▇▇▇ 66 Company, or any ▇▇▇▇▇▇▇▇ 66 Affiliate described in Section 6.02 (regardless whether such act or failure to act is covered by a Ruling, Unqualified Tax Opinion or waiver described in clause (x), (y) or (z) of Section 6.02(d), a Board Certificate described in Section 6.02(e) or a consent described in Section 6.02(f) or (g)) or (v) any breach by ▇▇▇▇▇▇▇▇ 66 of its agreement and representation set forth in Section 6.01(a).

(b) For purposes of calculating the amount and timing of any Tax-Related Loss for which ▇▇▇▇▇▇▇▇ 66 is responsible under this Section 6.04, Tax-Related Losses shall be calculated by assuming that ConocoPhillips, ConocoPhillips Company, the ConocoPhillips Affiliated Group and each member of the ConocoPhillips Group (I) pay Tax at the highest marginal corporate Tax rates in effect in each relevant taxable year and (II) have no Tax Attributes in any relevant taxable year.

Section 7. Assistance and Cooperation.

Section 7.01 Assistance and Cooperation.

(a) General. Each of the Companies shall cooperate (and cause its respective Affiliates to cooperate) with the other Company and with the other Company’s agents, representatives or advisors, including accounting firms and legal counsel, in connection with Tax matters relating to the Companies and their Affiliates including (i) preparation and filing of Tax Returns, (ii) determining the liability for and amount of any Taxes due (including estimated Taxes) or the right to and amount of any refund of Taxes, (iii) determining any amounts required to be paid pursuant to this Agreement, (iv) examinations of Tax Returns, and (v) any administrative or judicial proceeding in respect of Taxes assessed or proposed to be assessed or claims for refunds. Such cooperation shall include, without limitation, (x) preparing Tax Packages and providing information and documents as provided in Section 7.02, (y) making all information and documents in their possession relating to the other Company and its Affiliates available to such other Company as provided in Section 8, and (z) making available to the other Company, as reasonably requested and available, personnel (including officers, directors, employees and agents of the Companies or their respective Affiliates) responsible for preparing, maintaining, and interpreting information and documents relevant to Taxes, and personnel reasonably required as witnesses or for purposes of providing information or documents in connection with any administrative or judicial proceedings relating to Taxes. In the event that a member of the ConocoPhillips Group, on the one hand, or a member of the ▇▇▇▇▇▇▇▇ 66 Group, on the other hand, suffers a Tax detriment as a result of a Transfer Pricing Adjustment, the Companies shall cooperate pursuant to this Section 7 to seek any competent authority relief that may be available with respect to such Transfer Pricing Adjustment.

(b) Confidentiality. Any information or documents provided under this Section 7 shall be kept confidential by the Company receiving the information or documents, except as may otherwise be necessary in connection with the filing of Tax Returns or in connection with any administrative or judicial proceedings relating to Taxes. Notwithstanding any other provision of this Agreement or any other agreement, (i) neither ConocoPhillips nor any ConocoPhillips Affiliate shall be required to provide ▇▇▇▇▇▇▇▇ 66 or any ▇▇▇▇▇▇▇▇ 66 Affiliate or any other Person access to or copies of any information or procedures (including the proceedings of any Tax Contest) other than information or procedures that relate solely to ▇▇▇▇▇▇▇▇ 66, the business or assets of ▇▇▇▇▇▇▇▇ 66 or any ▇▇▇▇▇▇▇▇ 66 Affiliate and (ii) in no event shall ConocoPhillips or any ConocoPhillips Affiliate be required to provide ▇▇▇▇▇▇▇▇ 66, any ▇▇▇▇▇▇▇▇ 66 Affiliate or any other Person access to or copies of any information if such action could reasonably be expected to result in the waiver of any Privilege. In addition, in the event that ConocoPhillips determines that the provision of any information to ▇▇▇▇▇▇▇▇ 66 or any ▇▇▇▇▇▇▇▇ 66 Affiliate could be commercially detrimental, violate any Law or agreement or waive any Privilege, the parties shall use reasonable best efforts to permit compliance with their respective obligations under this Section 7 in a manner that avoids any such harm or consequence.

Section 7.02 Tax Packages and Other Tax Return Information.

(a) General. ▇▇▇▇▇▇▇▇ 66, ▇▇▇▇▇▇▇▇ 66 Company, ConocoPhillips, and ConocoPhillips Company acknowledge that time is of the essence in relation to any request for information, assistance or cooperation made by ConocoPhillips or ▇▇▇▇▇▇▇▇ 66 pursuant to Section 7.01 or this

Section 7.02. ▇▇▇▇▇▇▇▇ 66, ▇▇▇▇▇▇▇▇ 66 Company, ConocoPhillips, and ConocoPhillips Company acknowledge that failure to conform to the deadlines set forth herein or reasonable deadlines otherwise set by ConocoPhillips or ▇▇▇▇▇▇▇▇ 66 could cause irreparable harm.

(b) Tax Packages. ▇▇▇▇▇▇▇▇ 66 (if ConocoPhillips is the Responsible Company with respect to the applicable Tax Returns) or ConocoPhillips (if ▇▇▇▇▇▇▇▇ 66 is the Responsible Company with respect to the applicable Tax Returns) shall provide to the Responsible Company a package containing information and documents relating to its Group required by the Responsible Company to prepare and file the applicable Tax Returns (“Tax Packages”). ▇▇▇▇▇▇▇▇ 66 or ConocoPhillips, as applicable, shall provide such Tax Packages (i) containing information or documents in such form as the Responsible Company reasonably requests (or, in the absence of such request, in such form as historically provided to the Responsible Company for the purposes of preparing and filing the applicable Tax Returns) and (ii) in sufficient time for the Responsible Company to file the applicable Tax Returns on a timely basis.

Section 7.03 Reliance by ConocoPhillips. If any member of the ▇▇▇▇▇▇▇▇ 66 Group supplies information to a member of the ConocoPhillips Group in connection with a Tax liability and an officer of a member of the ConocoPhillips Group signs a statement or other document under penalties of perjury in reliance upon the accuracy of such information, then upon the written request of such member of the ConocoPhillips Group identifying the information being so relied upon, the chief financial officer of ▇▇▇▇▇▇▇▇ 66 (or any officer of ▇▇▇▇▇▇▇▇ 66 as designated by the chief financial officer of ▇▇▇▇▇▇▇▇ 66) shall certify in writing that to his or her knowledge (based upon consultation with appropriate employees) the information so supplied is accurate and complete. Each of ▇▇▇▇▇▇▇▇ 66 and ▇▇▇▇▇▇▇▇ 66 Company agrees to indemnify and hold harmless each member of the ConocoPhillips Group and its directors, officers and employees from and against any fine, penalty, or other cost or expense of any kind attributable to a member of the ▇▇▇▇▇▇▇▇ 66 Group having supplied, pursuant to this Section 7, a member of the ConocoPhillips Group with inaccurate or incomplete information in connection with a Tax liability.

Section 8. Tax Records.

Section 8.01 Retention of Tax Records. Each Company shall preserve and keep all Tax Records exclusively relating to the assets and activities of its Group for Pre-Distribution Periods, and ConocoPhillips shall preserve and keep all other Tax Records relating to Taxes of the Groups for Pre-Distribution Tax Periods, for so long as the contents thereof may become material in the administration of any matter under the Code or other applicable Tax Law, but in any event until the later of (a) the expiration of any applicable statutes of limitations, or (b) seven years after the Distribution Date (such later date, the “Retention Date”). After the Retention Date, each Company may dispose of such Tax Records upon 90 days’ prior written notice to the other Company. If, prior to the Retention Date, a Company reasonably determines that any Tax Records which it would otherwise be required to preserve and keep under this Section 8 are no longer material in the administration of any matter under the Code or other applicable Tax Law and the other Company agrees, then such first Company may dispose of such Tax Records upon 90 days’ prior notice to the other Company. Any notice of an intent to dispose given pursuant to this Section 8.01 shall include a list of the Tax Records to be disposed of describing in reasonable detail each file, book, or other record accumulation being disposed. The notified Company shall have the opportunity, at its cost and expense, to copy or remove, within such 90-

day period, all or any part of such Tax Records. If, at any time prior to the Retention Date, ▇▇▇▇▇▇▇▇ 66 or ▇▇▇▇▇▇▇▇ 66 Company determines to decommission or otherwise discontinue any computer program or information technology system used to access or store any Tax Records, then ▇▇▇▇▇▇▇▇ 66 or ▇▇▇▇▇▇▇▇ 66 Company may decommission or discontinue such program or system upon 90 days’ prior notice to ConocoPhillips and ConocoPhillips shall have the opportunity, at its cost and expense, to copy, within such 90-day period, all or any part of the underlying data relating to the Tax Records accessed by or stored on such program or system.

Section 8.02 Access to Tax Records. The Companies and their respective Affiliates shall make available to each other for inspection and copying during normal business hours upon reasonable notice all Tax Records (and, for the avoidance of doubt, any pertinent underlying data accessed or stored on any computer program or information technology system) in their possession and shall permit the other Company and its Affiliates, authorized agents and representatives and any representative of a Taxing Authority or other Tax auditor direct access during normal business hours upon reasonable notice to any computer program or information technology system used to access or store any Tax Records, in each case to the extent reasonably required by the other Company in connection with the preparation of Tax Returns or financial accounting statements, audits, litigation, or the resolution of items under this Agreement.

Section 9. Tax Contests.

Section 9.01 Notice. Each of the Companies shall provide prompt notice to the other Company of any written communication from a Tax Authority regarding any pending or threatened Tax audit, assessment or proceeding or other Tax Contest of which it or its Affiliate becomes aware related to Taxes for Tax Periods for which it is indemnified by the other Company hereunder. Such notice shall attach copies of the pertinent portion of any written communication from a Tax Authority and contain factual information (to the extent known) describing any asserted Tax liability in reasonable detail and shall be accompanied by copies of any notice and other documents received from any Tax Authority in respect of any such matters; provided, however, that the Indemnitor shall not be relieved of its obligations hereunder by reason of any failure by the Indemnitee to so notify except to the extent the Indemnitor was materially harmed by such failure.

Section 9.02 Control of Tax Contests.

(a) Separate Returns. In the case of any Tax Contest with respect to any Separate Return for any Pre-Distribution Period or any Straddle Period:

(i) If the Tax Contest relates exclusively to Taxes for which ▇▇▇▇▇▇▇▇ 66 is responsible under Section 2, ▇▇▇▇▇▇▇▇ 66 shall have exclusive control over such Tax Contest, except insofar as ConocoPhillips shall have exclusive control over such Tax Contest pursuant to Section 9.02(a)(ii)(B) and subject to Section 9.02(c)(i) and (d) below; and

(ii) If the Tax Contest relates (A) exclusively to Taxes for which ConocoPhillips is responsible under Section 2, (B) exclusively to Taxes for which ▇▇▇▇▇▇▇▇ 66 is responsible under Section 2 and ConocoPhillips determines in good faith that ▇▇▇▇▇▇▇▇ 66 has failed to defend diligently such Tax Contest, or (C) to Taxes for which both ConocoPhillips and

▇▇▇▇▇▇▇▇ 66 are responsible under Section 2, ConocoPhillips shall (in the case of Tax Contests described in Section 9.02(a)(ii)(B), at ConocoPhillips’ option) have exclusive control over the Tax Contest, subject to Section 9.02(c)(i) and (d) below.

(b) Joint Returns. In the case of any Tax Contest with respect to any ConocoPhillips Federal Consolidated Income Tax Return, ConocoPhillips State Combined Income Tax Return or other Joint Return, in each case, for any Pre-Distribution Period or Straddle Period, ConocoPhillips shall have exclusive control over the Tax Contest, including exclusive authority with respect to any settlement of such Tax liability, subject to Section 9.02(c)(ii) below.

(c) Settlement Rights and Certain Other Rights.

(i) Separate Returns. In the case of any Tax Contest with respect to any Separate Return, the Controlling Party shall have the sole right to contest, litigate, compromise and settle any such Tax Contest without obtaining the prior consent of the Non-Controlling Party; provided, however, that if ▇▇▇▇▇▇▇▇ 66 is the Controlling Party with respect to any Tax Contest with respect to any Separate Return which Tax Contest would reasonably be expected to have an adverse impact on ConocoPhillips, ▇▇▇▇▇▇▇▇ 66 shall not compromise or settle such Tax Contest without obtaining the prior consent of ConocoPhillips. Unless waived by the parties in writing, in connection with any potential adjustment in such Tax Contest (x) with respect to any Separate Return as a result of which adjustment the Non-Controlling Party may reasonably be expected to become liable to make any indemnification payment (or any payment under Section 2.07) to the Controlling Party under this Agreement or (y) with respect to any Specified Separate Return: (A) the Controlling Party shall keep the Non-Controlling Party informed in a timely manner of all actions taken or proposed to be taken by the Controlling Party with respect to such potential adjustment in such Tax Contest; (B) the Controlling Party shall provide the Non-Controlling Party copies of any written materials relating to such potential adjustment in such Tax Contest received from any Tax Authority; (C) the Controlling Party shall consult with the Non-Controlling Party before submitting any written materials prepared or furnished in connection with such potential adjustment in such Tax Contest and shall offer the Non-Controlling Party a reasonable opportunity to comment before submitting any such written materials; and (D) the Controlling Party shall timely provide the Non-Controlling Party with copies of any correspondence or filings submitted to any Tax Authority or judicial authority in connection with such potential adjustment in such Tax Contest. The failure of the Controlling Party to take any action specified in the preceding sentence with respect to the Non-Controlling Party shall not relieve the Non-Controlling Party of any liability and/or obligation which it may have to the Controlling Party under this Agreement except to the extent that the Non-Controlling Party was materially harmed by such failure, and in no event shall such failure relieve the Non-Controlling Party from any other liability or obligation which it may have to the Controlling Party.

(ii) Joint Returns. In the case of any Tax Contest with respect to Joint Returns, the Controlling Party shall have the sole right to contest, litigate, compromise and settle any such Tax Contest without obtaining the prior consent of the Non-Controlling Party. Unless waived by the parties in writing, in connection with any potential adjustment in such Tax Contest as a result of which adjustment the Non-Controlling Party may

reasonably be expected to become liable to make any indemnification payment (or any payment under Section 2.07) to the Controlling Party under this Agreement: (A) the Controlling Party shall keep the Non-Controlling Party informed in a timely manner of all actions taken or proposed to be taken by the Controlling Party with respect to such potential adjustment in such Tax Contest; (B) the Controlling Party shall provide the Non-Controlling Party copies of any written materials relating to such potential adjustment in such Tax Contest received from any Tax Authority; and (C) the Controlling Party shall consult with the Non-Controlling Party before submitting any written materials prepared or furnished in connection with such potential adjustment in such Tax Contest. ▇▇▇▇▇▇▇▇ 66 shall not be entitled to attend meetings or teleconferences with the Tax Authority in connection with any Tax Contest with respect to any Joint Returns, except that, in connection with any Special Joint Tax Contest, ▇▇▇▇▇▇▇▇ 66 shall be entitled to attend such portion of any meeting or teleconference as pertains to ▇▇▇▇▇▇▇▇ 66. The failure of the Controlling Party to take any action specified in the second preceding sentence with respect to the Non-Controlling Party shall not relieve the Non-Controlling Party of any liability and/or obligation which it may have to the Controlling Party under this Agreement except to the extent that the Non-Controlling Party was materially harmed by such failure, and in no event shall such failure relieve the Non-Controlling Party from any other liability or obligation which it may have to the Controlling Party. ConocoPhillips shall be entitled to permit ▇▇▇▇▇▇▇▇ 66 to conduct any portion of a Special Joint Tax Contest on such terms and conditions as ConocoPhillips shall determine in its sole discretion.

(d) Tax Contest Participation. In the case of any Tax Contest with respect to any Separate Return, unless waived by the parties in writing, the Controlling Party shall provide the Non-Controlling Party with written notice reasonably in advance of, and the Non-Controlling Party shall have the right to attend, any formally scheduled meetings with Tax Authorities or hearings or proceedings before any judicial authorities in connection with any potential adjustment in a Tax Contest pursuant to which the Non-Controlling Party may reasonably be expected to become liable to make any indemnification payment (or any payment under Section 2.07) to the Controlling Party under this Agreement or with respect to any Specified Separate Return. The failure of the Controlling Party to provide any notice specified in this Section 9.02(d) to the Non-Controlling Party shall not relieve the Non-Controlling Party of any liability and/or obligation which it may have to the Controlling Party under this Agreement except to the extent that the Non-Controlling Party was materially harmed by such failure, and in no event shall such failure relieve the Non-Controlling Party from any other liability or obligation which it may have to the Controlling Party.

(e) Power of Attorney. Each member of the ▇▇▇▇▇▇▇▇ 66 Group shall execute and deliver to ConocoPhillips (or such member of the ConocoPhillips Group as ConocoPhillips shall designate) any power of attorney or other similar document reasonably requested by ConocoPhillips (or such designee) in connection with any Tax Contest (as to which ConocoPhillips is the Controlling Party) described in this Section 9.

This Agreement shall be effective as of the date hereof. As of the date hereof, (a) all prior intercompany Tax allocation agreements shall be terminated, and (b) amounts due under such agreements as of the date hereof shall be settled before the Distribution Date. Upon such termination and settlement, no further payments by or to ConocoPhillips, ▇▇▇▇▇▇▇▇ 66 or any member of their respective Group, with respect to such agreements shall be made, and all other rights and obligations resulting from such agreements between the Companies and their Affiliates shall cease at such time. The prior practice of ConocoPhillips of creating intercompany obligations in respect of Tax allocations with respect to the ▇▇▇▇▇▇▇▇ 66 Business shall be terminated effective immediately prior to the Distribution on the Distribution Date, and amounts due under any such remaining intercompany obligations shall be settled in the ordinary course.

(a) ConocoPhillips shall procure that (if one has not already been made) an application shall be made to HM Revenue & Customs pursuant to section 43B of the Value Added Tax ▇▇▇ ▇▇▇▇ for the exclusion of each member of the ▇▇▇▇▇▇▇▇ 66 Group that has previously been a member of ConocoPhillips UK Topco’s VAT group from the bodies corporate treated as members of ConocoPhillips UK Topco’s VAT group and for such exclusion to take effect from the time of the Distribution or, if HM Revenue & Customs do not permit this, at the earliest date following the Distribution permitted.

(b) ▇▇▇▇▇▇▇▇ 66 shall contribute, or shall procure that each member of the ▇▇▇▇▇▇▇▇ 66 Group which was a member of ConocoPhillips UK Topco’s VAT group contributes, to the representative member of such VAT group such proportion of any VAT for which the representative member is accountable as is properly attributable to supplies, acquisitions and importations (“supplies”) made by each member of the ▇▇▇▇▇▇▇▇ 66 Group whilst a member of ConocoPhillips UK Topco’s VAT group (less such amount of deductible input tax as is properly attributable to such supplies), such contribution to be made in cleared funds on the day which is the later of 30 days after demand is made therefor, and four Business Days before the day on which the representative member is required to account for such VAT to HM Revenue & Customs. ConocoPhillips shall pay, or shall procure that there is paid, to Immingham CHP LLP (on behalf of itself and each other relevant member of the ▇▇▇▇▇▇▇▇ 66 Group) an amount equivalent to such proportion of any repayment of VAT received by the representative member from HM Revenue & Customs or of any credit obtained by reference to an excess of deductible input tax over output tax that is properly attributable to supplies made to and by members of the ▇▇▇▇▇▇▇▇ 66 Group whilst members of ConocoPhillips UK Topco’s VAT group (but excluding any part of such repayment or credit that is attributable to interest payable by HM Revenue & Customs), promptly after its receipt by, or offset against a liability of, the representative member. ▇▇▇▇▇▇▇▇ 66 shall provide such information as may be required to enable the representative member to make the returns and provide the information required to be provided for VAT purposes.

(b) ▇▇▇▇▇▇▇▇ 66 shall procure that each member of the ▇▇▇▇▇▇▇▇ 66 Group which was a member of the UK GPA contributes to the UK Nominated Company, within 30 days after written demand is made therefor (or, if later, four Business Days before the amount becomes due and payable to HM Revenue & Customs), an amount equal to any instalment of UK Corporation Tax which is to be or has been discharged by the UK Nominated Company on behalf of the member of the ▇▇▇▇▇▇▇▇ 66 Group in question pursuant to the UK GPA (including, without limitation, through payment of a balance of monies payable pursuant to the UK GPA) as certified by the UK Nominated Company (but, for the avoidance of doubt, not including any amount in respect of interest payable in respect of any such instalment of UK Corporation Tax to HM Revenue & Customs), provided that no such contribution shall be made to the extent that such contribution was made prior to or at the time of the Distribution.

(c) ConocoPhillips shall:

(ii) procure that the UK Nominated Company shall (subject to paragraph (iii) below) apportion to the relevant member of the ▇▇▇▇▇▇▇▇ 66 Group each amount contributed before or after the Distribution to the UK Nominated Company by any member of the ▇▇▇▇▇▇▇▇ 66 Group pursuant to the UK GPA in respect of any instalment of UK Corporation Tax (a “Contributed Amount”), such apportionment to be made by reference to the instalment or instalments of UK Corporation Tax in respect of which the Contributed Amount was paid; and

(iii) within 30 days after the relevant UK Corporation Tax has finally been apportioned, pay, or procure that there is paid, to the relevant member of the ▇▇▇▇▇▇▇▇ 66 Group an amount equal to any excess of any Contributed Amount in respect of any instalment of UK Corporation Tax over the amount of UK Corporation Tax finally apportioned to that member of the ▇▇▇▇▇▇▇▇ 66 Group in respect of that instalment (for the avoidance of doubt, taking no account of any interest payable by HM Revenue & Customs in respect of such excessive Contributed Amount).

Paragraph 3. Group Relief Surrenders between the Groups.

Paragraph 3.01. ConocoPhillips and ▇▇▇▇▇▇▇▇ 66 shall procure that after the Distribution no claim, election, surrender, notice or consent is made in respect of any Group Relief Surrender by a member of the ConocoPhillips Group to a member of the ▇▇▇▇▇▇▇▇ 66 Group (or vice versa) other than pursuant to this Paragraph 3.

Paragraph 3.02.

Paragraph 3.04. If the amount of any Corresponding Relievable Loss is certified by the person to whom that loss arises to be in fact less than the amount given for that Corresponding Relievable Loss in Appendix 1, then the amount of any Agreed UK Group Relief Surrender in respect of that Corresponding Relievable Loss will be reduced accordingly. Any necessary allocation of the reduction shall be determined by ▇▇▇▇▇▇▇▇ 66 (if the reduction is in a Corresponding Relievable Loss assumed to be surrendered to more than one member of the ▇▇▇▇▇▇▇▇ 66 Group) or by ConocoPhillips (if the reduction is in a Corresponding Relievable Loss assumed to be surrendered to more than one member of the ConocoPhillips Group).

Paragraph 3.05. If a person who is a member of a Group has a Corresponding Relievable Loss in respect of a UK Accounting Period referred to in Appendix 1 which is in fact greater than a Corresponding Relievable Loss assumed for that member in Appendix 1, the amount thereof shall be certified by that person as soon as reasonably practicable to ▇▇▇▇▇▇▇▇ 66 (where the person with the Corresponding Relievable Loss is a member of the ConocoPhillips Group) or to ConocoPhillips (where the person with the Corresponding Relievable Loss is a member of the ▇▇▇▇▇▇▇▇ 66 Group) and an Agreed UK Group Relief Surrender in respect of that Corresponding Relievable Loss may, if requested by ▇▇▇▇▇▇▇▇ 66 or ConocoPhillips, as the case may be, for the other Group, be increased or made (including as an additional Group Relief Surrender to another member of the other Group) but only to the extent that the amount of the Corresponding Relievable Loss that exceeds the amount set out for that Corresponding Relievable Loss in Appendix 1 cannot be used by the person to whom that Corresponding Relievable Loss arises, or by another member of the same UK Tax Group, other than in a UK Accounting Period of that person subsequent to the UK Accounting Period in which that Corresponding Relievable Loss arises.

Paragraph 3.06. Subject to the other provisions of this Paragraph 3, if a company which is a member of a UK Tax Group has lower profits available to be relieved by a Group Relief Surrender than are assumed by Appendix 1 then ▇▇▇▇▇▇▇▇ 66 (in the case of the ▇▇▇▇▇▇▇▇ 66 UK Tax Group) or ConocoPhillips (in the case of the ConocoPhillips UK Tax Group) may require that a Group Relief Surrender of all or part of the Corresponding Relievable Loss in question is reallocated to another member of the same UK Tax Group.

Paragraph 3.07. ConocoPhillips and ▇▇▇▇▇▇▇▇ 66 shall each use all reasonable endeavors as respects its Group to procure that claims, adjustments, elections, surrenders, notices, consents (including adjustments to any of these) and other procedural matters required to give effect to this Paragraph 3 shall occur, within applicable UK Time Limits.

ConocoPhillips and ▇▇▇▇▇▇▇▇ 66 shall use all reasonable endeavors to procure that (a) the claims for Rollover Relief and Holdover Relief listed in Part A of Appendix 2 (if any) shall be made and not later amended and (b) adjustments, elections, surrenders, notices, consents (including adjustments to any of these) and other procedural matters required to give effect to such claims shall occur, within applicable UK Time Limits. ConocoPhillips and ▇▇▇▇▇▇▇▇ 66 shall procure that no amendment is made to the claims for Rollover Relief or Holdover Relief made prior to the Distribution and listed in Part B of Appendix 2.
