Section 4.02 Valero’s Responsibility. Valero has the exclusive obligation and right to prepare and file, or to cause to be prepared and filed:

(a) General Rule. Except as provided in Section 4.04(b), any Tax Return that Corner Store has the obligation and right to prepare and file, or cause to be prepared and filed, under Section 4.03, for any Pre-Deconsolidation Period or any Straddle Period (or any taxable period beginning after the Deconsolidation Date to the extent items reported on such Tax Return might reasonably be expected to affect items reported on any Tax Return for any Pre-Deconsolidation Period or any Straddle Period) shall be prepared in accordance with past practices, accounting methods, elections or conventions (“Past Practices”) used with respect to the Tax Returns in question (unless there is no reasonable basis, as jointly determined by the parties, for the use of such Past Practices or unless there is no adverse effect to Valero), and to the extent any items are not covered by Past Practices (or in the event that there is no reasonable basis, as jointly determined by the parties, for the use of such Past Practices or there is no adverse effect to Valero), in accordance with reasonable Tax accounting practices selected by Corner Store. Except as provided in Section 4.04(b), Valero shall prepare any Tax Return which it has the obligation and right to prepare and file, or cause to be prepared and filed, under Section 4.02, in accordance with Past Practice (unless there is no reasonable basis, as jointly determined by the parties, for the use of such Past Practice or unless there is no adverse effect to Corner Store), and to the extent any items are not covered by Past Practices (or in the event that there is no reasonable basis, as jointly determined by the parties, for the use of such Past Practices or there is no adverse effect to Corner Store), in accordance with reasonable Tax accounting practices

selected by Valero. Notwithstanding the foregoing, Corner Store shall prepare all Tax Returns of the Corner Store Group for any period in a manner consistent with the Specified Valuation and shall not take any position in any Tax Return, Tax Contest or otherwise for tax purposes that is inconsistent with the Specified Valuation, unless there is no reasonable basis, as jointly determined by the parties, for preparing such Tax Returns or taking such positions in a manner consistent with the Specified Valuation.

(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. The Tax treatment reported on any Tax Return for which Corner Store is the Responsible Party shall be consistent with that on any Tax Return filed or to be filed by Valero or any member of the Valero Group or caused or to be caused to be filed by Valero, in each case with respect to periods prior to the Distribution Date or with respect to Straddle Periods (“Valero Group Transaction Returns”), to the extent Valero notifies Corner Store in writing of 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 Valero Group Transaction Returns, the Tax treatment to be reported on any Tax Return shall be determined by Valero and the Responsible Company shall not take any position on any Tax Return that is inconsistent with such determination, provided that if (i) there is no reasonable basis, in the opinion of a Tax advisor from a nationally recognized legal, accounting or professional tax services firm, for the Tax treatment determined by Valero, or (ii) such Tax treatment is inconsistent with the Tax treatment contemplated in the Ruling Requests, the Tax Opinions/Rulings and/or the Valero Group Transaction Returns, then such Tax Return shall be submitted for review pursuant to Section 4.06(a), and any dispute regarding such proper Tax treatment shall be referred for resolution pursuant to Section 14, 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.

(a) Corner Store will elect and join, and will cause its respective Affiliates to elect and join, in filing any Valero State Combined Income Tax Returns, Valero Foreign Combined Income Tax Returns, Split Valero State Combined Income Tax Returns and any Joint Returns that Valero determines are required to be filed or that Valero chooses to file pursuant to Sections 4.02(b) and 4.05(b). With respect to any Corner Store Separate Returns relating to any Tax Period (or portion thereof) ending on or prior to the Distribution Date, Corner Store will elect and join, and will cause its respective Affiliates to elect and join, in filing consolidated, unitary, combined, or other similar joint Tax Returns, to the extent each entity is eligible to join in such Tax Returns, if Valero reasonably determines that the filing of such Tax Returns is consistent with past reporting practices, or, in the absence of applicable past practices, will result in the minimization of the net present value of the aggregate Tax to the entities eligible to join in such Tax Returns.

(b) At Valero’s discretion, Valero may amend any Valero State Combined Income Tax Return or propose in respect of an audit of any Valero State Combined Income Tax Return, or use any other means available, including filing additional Corner Store Separate Returns, in order to separate such Valero State Combined Income Tax Return into one or more consolidated, unitary or combined state income Tax Returns (each a “Split Valero State Combined Income Tax

Return”). Corner Store shall cooperate with Valero in the filing of any additional Corner Store Separate Returns, including by providing any necessary powers of attorney, signing Tax Returns, amending any Tax Returns that Corner Store has the obligation and right to prepare and file pursuant to Section 4.03 and complying with its obligations under Section 8 hereof.

Section 4.06 Right to Review Tax Returns.

(a) General. The Responsible Company with respect to any material Tax Return shall make such Tax Return and related workpapers available for review by the other Company, if requested, to the extent (i) such Tax Return relates to Taxes for which the requesting party would reasonably be expected to be liable, (ii) such Tax Return relates to Taxes and the requesting party would reasonably be expected to be liable 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, or (iv) the requesting party reasonably determines that it must inspect such Tax Return to confirm compliance with the terms of this Agreement. The Responsible Company shall use its reasonable best efforts to make such Tax Return available for review as required under this paragraph sufficiently in advance of the due date for filing of such Tax Return to provide the requesting party with a meaningful opportunity to analyze and comment on such Tax Return and shall use its reasonable best efforts to have such Tax Return modified before filing, taking into account the person responsible for payment of the Tax (if any) reported on such Tax Return and whether the amount of Tax liability with respect to such Tax Return is material. The Companies shall attempt in good faith to resolve any issues arising out of the review of such Tax Return. For purposes of this Section 4.06(a), a Tax Return is “material” if it could reasonably be expected to reflect (A) Tax liability equal to or in excess of $1 million, (B) a credit or credits equal to or in excess of $1 million or (C) a loss or losses equal to or in excess of $3 million. Notwithstanding anything to the contrary in this Agreement, Valero shall not be required to provide Corner Store with any Valero Federal Consolidated Income Tax Returns, Valero State Combined Income Tax Returns, Valero Foreign Combined Income Tax Returns or Valero Separate Returns, or any workpapers related to such Tax Returns.

(b) 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 by its authorized representative), the Company which is legally required to sign such Tax Return shall not be required to sign such Tax Return under this Agreement if there is no reasonable basis, in the opinion of a Tax advisor from a nationally recognized legal, accounting or professional tax services firm, for the Tax treatment of any item reported on the Tax Return or the Tax treatment of any 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 authorized representatives) to material penalties.

Section 4.07 Corner Store Carrybacks and Claims for Refund. Corner Store hereby agrees that, unless Valero consents in writing, (i) no Adjustment Request with respect to any Joint Return (or any Return of Other Taxes described in clause (II) of Section 5.02) shall be filed, and (ii) any available elections to waive the right to claim in any Pre-Deconsolidation

Period with respect to any Joint Return (or any Return of Other Taxes described in clause (II) of Section 5.02) any Corner Store Carryback arising in a Post-Deconsolidation Period shall be made, and no affirmative election shall be made to claim any such Corner Store Carryback; provided, however, that the parties agree that any such Adjustment Request shall be made with respect to any Corner Store Carryback related to U.S. federal or State Taxes, upon the reasonable request of Corner Store, if such Corner Store Carryback is necessary to prevent the loss of the federal and/or State Tax Benefit of such Corner Store Carryback (including, but not limited to, an Adjustment Request with respect to a Corner Store Carryback of a federal or State capital loss arising in a Post-Deconsolidation Period to a Pre-Deconsolidation Period) and such Adjustment Request, based on Valero’s sole, reasonable determination, will cause no Tax detriment to Valero, the Valero Group or any member of the Valero Group. Any Adjustment Request which Valero consents to make under this Section 4.07 shall be prepared and filed by the Responsible Company for the Tax Return to be adjusted.

Section 4.08 Apportionment of Earnings and Profits and Tax Attributes. Valero shall in good faith advise Corner Store 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 Valero determines shall be allocated or apportioned to the Corner Store Group under applicable law. Corner Store and all members of the Corner Store 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 Valero and Corner Store collectively agree to make such election. As soon as practicable after receipt of a written request from Corner Store, Valero shall provide copies of any studies, reports, and workpapers supporting the earnings and profits and other Tax Attributes allocable to Corner Store. Any dispute regarding the apportionment of such earnings and profits or any Tax Attribute shall be resolved pursuant to the provisions of Section 14 of this Agreement. All Tax Returns that are required to be filed under this Agreement after such resolution shall be filed in accordance with such resolution. In the event of a subsequent adjustment to the earnings and profits or any Tax Attributes determined by Valero, Valero shall promptly notify Corner Store in writing of such adjustment. For the absence of doubt, Valero shall not be liable to Corner Store or any member of the Corner Store Group for any failure of any determination under this Section 4.08 to be accurate under applicable law.

Section 5. Tax Payments.

Section 5.01 Payment of Taxes with Respect to Valero Federal Consolidated Income Tax Returns.

(c) Adjustments Resulting in Underpayments. In the case of any adjustment pursuant to a Final Determination with respect to any such Tax Return, the Responsible Company shall pay to the applicable Tax Authority when due any additional Tax due with respect to such Return required to be paid as a result of such adjustment pursuant to a Final Determination. The Responsible Company shall compute the amount attributable to the Corner Store Group in accordance with Section 2 and Corner Store shall pay to Valero any amount due Valero (or Valero shall pay Corner Store any amount due Corner Store) under Section 2 within 30 days from the later of (i) the date the additional Tax was paid by the Responsible Company or (ii) the date of receipt of a written notice and demand from the Responsible Company for payment of the amount due, accompanied by evidence of payment and a statement detailing the Taxes paid and describing in reasonable detail the particulars relating thereto.

Section 5.04 Indemnification Payments.

(a) If any Company (the “Payor”) is required under applicable Tax Law to pay to a Tax Authority a Tax that another Company (the “Required Party”) is liable for under this Agreement, the Required Party shall pay the Payor the amount of such Tax (and any other amount required to be paid by the Required Party to the Payor pursuant to this Agreement in connection with such payment) no later than 5 days prior to the due date for payment of such amount by the Payor to the applicable Tax Authority (including any applicable extensions).

(b) All indemnification payments under this Agreement shall be made by Valero directly to Corner Store and by Corner Store directly to Valero; provided, however, that if the Companies mutually agree with respect to any such indemnification payment, any member of the Valero Group, on the one hand, may make such indemnification payment to any member of the Corner Store Group, on the other hand, and vice versa.

Section 6. Tax Benefits.

Section 6.01 Tax Benefits.

(a) Except as set forth below, Valero shall be entitled to any refund (and any interest thereon received from the applicable Tax Authority) of Income Taxes and Other Taxes for which Valero is liable hereunder, Corner Store shall be entitled to any refund (and any interest thereon received from the applicable Tax Authority) of Income Taxes and Other Taxes for which Corner Store is liable hereunder and a Company receiving a refund to which another Company is entitled hereunder shall pay over such refund to such other Company within 30 days after such refund is received (together with interest computed at the Prime Rate based on the number of days from the date the refund was received to the date the refund was paid over).

(b) If a member of the Corner Store Group actually realizes in cash any Tax Benefit as a result of an adjustment (other than an adjustment set forth in Schedule 6.01(b), as such Schedule 6.01(b) may be amended by mutual agreement by the Companies prior to the Distribution Date) pursuant to a Final Determination to any Taxes for which a member of the Valero Group is liable hereunder (or any Tax Attribute of a member of the Valero Group) and such Tax Benefit would not have arisen but for such adjustment (determined on a “with and without” basis), or if a member of the Valero Group actually realizes in cash any Tax Benefit as a result of an adjustment (other than an adjustment set forth in Schedule 6.01(b), as such Schedule 6.01(b) may be amended by mutual agreement by the Companies prior to the Distribution Date) pursuant to a Final Determination to any Taxes for which a member of the Corner Store Group is liable hereunder (or any Tax Attribute of a member of the Corner Store Group) and such Tax Benefit would not have arisen but for such adjustment (determined on a “with and without” basis), Corner Store or Valero, as the case may be, shall make a payment to either Valero or Corner Store, as appropriate, within 30 days following such actual realization of the Tax Benefit, in an amount equal to such Tax Benefit actually realized in cash (including any Tax Benefit actually realized as a result of the payment), plus interest on such amount computed at the Prime Rate based on the number of days from the date of such actual realization of the Tax Benefit to the date of payment of such amount under this Section 6.01(b).

(c) No later than 30 days after a Tax Benefit described in Section 6.01(b) is actually realized in cash by a member of the Valero Group or a member of the Corner Store Group, Valero (if a member of the Valero Group actually realizes such Tax Benefit) or Corner Store (if a member of the Corner Store Group actually realizes such Tax Benefit) shall provide the other Company with a written calculation of the amount payable to such other Company by Valero or Corner Store pursuant to this Section 6. In the event that Valero or Corner Store disagrees with

any such calculation described in this Section 6.01(c), Valero or Corner Store shall so notify the other Company in writing within 30 days of receiving the written calculation set forth above in this Section 6.01(c). Valero and Corner Store shall endeavor in good faith to resolve such disagreement, and, failing that, the amount payable under this Section 6 shall be determined in accordance with the disagreement resolution provisions of Section 14 as promptly as practicable.

(d) Corner Store shall be entitled to any refund that is attributable to, and would not have arisen but for, a Corner Store Carryback pursuant to the proviso set forth in Section 4.07. Any such payment of such refund made by Valero to Corner Store pursuant to this Section 6.01(d) shall be recalculated in light of any Final Determination (or any other facts that may arise or come to light after such payment is made, such as a carryback of a Valero Group Tax Attribute to a Tax Period in respect of which such refund is received) that would affect the amount to which Corner Store is entitled, and an appropriate adjusting payment shall be made by Corner Store to Valero such that the aggregate amounts paid pursuant to this Section 6.01(d) equals such recalculated amount (with interest computed at the Prime Rate).

(e) Valero shall be entitled to any refund (and any interest thereon received from the applicable Tax Authority) of Taxes as a result of a Final Determination in respect of the Specified Tax Contest, and Corner Store shall, if it or any of its Affiliates receives such refund, pay over such refund to Valero within 30 days after such refund is received (together with interest computed at the Prime Rate based on the number of days from the date the refund was received to the date the refund was paid over and net of any Taxes imposed on Corner Store or such Affiliate with respect to the receipt of such refund).

Section 7.02 Restrictions on Corner Store.

(a) Corner Store agrees that it will not take or fail to take, or permit any Corner Store Affiliate to take or fail to take, any action where such action or failure to act would be inconsistent with or cause to be untrue any material, information, covenant or representation in any Representation Letters or Tax Opinions/Rulings. Corner Store agrees that it will not take or fail to take, or permit any Corner Store Affiliate, to take or fail to take, any action which prevents or could reasonably be expected to prevent (A) the Tax-Free Status, or (B) any transaction contemplated by the Separation and Distribution Agreement which is intended by the parties to be tax-free (including, but not limited to, those transactions listed on Schedule 7.02(a), as such Schedule 7.02(a) may be amended by mutual agreement by the Companies prior to the Distribution Date) from so qualifying, including, in the case of Corner Store, issuing any Corner Store Capital Stock that would prevent the Distribution from qualifying as a tax-free distribution within the meaning of Section 355 of the Code.

(b) Pre-Distribution Period. During the period from the date hereof until the completion of the Distribution, Corner Store shall not take any action (including the issuance of Corner Store Capital Stock) or permit any Corner Store Affiliate directly or indirectly controlled by Corner Store, as the case may be, to take any action if, as a result of taking such action, Corner Store could have a number of shares of Corner Store Capital Stock (computed on a fully diluted basis or otherwise) issued and outstanding, including by way of the exercise of stock options (whether or not such stock options are currently exercisable) or the issuance of restricted stock, that could cause Valero to cease to have Tax Control of Corner Store.

(c) Corner Store agrees that, from the date hereof until the first day after the two-year anniversary of the Distribution Date, it will (i) maintain its status as a company engaged in the Active Trade or Business for purposes of Section 355(b)(2) of the Code and (ii) not engage in any transaction that would result in it ceasing to be a company engaged in the Active Trade or Business for purposes of Section 355(b)(2) of the Code, in each case, taking into account Section 355(b)(3) of the Code.

(d) Corner Store agrees that, from the date hereof until the first day after the two-year anniversary of the Distribution Date, it will not

(ii) merge or consolidate with any other Person or liquidate or partially liquidate,

(iii) in a single transaction or series of transactions sell or transfer (other than sales or transfers of inventory in the ordinary course of business) all or substantially all of the assets that were transferred to Corner Store pursuant to the Contribution or sell or transfer 60% or more of the gross assets of the Active Trade or Business or 60% or more of the consolidated gross assets of Corner Store and its Affiliates (such percentages to be measured based on fair market value as of the Distribution Date),

(iv) redeem or otherwise repurchase (directly or through a Corner Store Affiliate) any Corner Store stock, or rights to acquire stock, except to the extent such repurchases satisfy Section 4.05(1)(b) of Revenue Procedure 96-30 (as in effect prior to the amendment of such Revenue Procedure by Revenue Procedure 2003-48),

(v) amend its certificate of incorporation (or other organizational documents), or take any other action, whether through a stockholder vote or otherwise, affecting the voting rights of Corner Store Capital Stock (including, without limitation, through the conversion of one class of Corner Store Capital Stock into another class of Corner Store Capital Stock) or

(vi) take or fail to take any other action or actions (including any action or transaction that would be reasonably likely to be inconsistent with any representation made in the Representation Letters or the Tax Opinions/Rulings) which in the aggregate (and taking into account any other transactions described in this subparagraph (d)) would be reasonably likely to have the effect of causing or permitting one or more persons (whether or not acting in concert) to acquire directly or indirectly stock representing a Fifty-Percent or Greater Interest in Corner Store or otherwise jeopardize the Tax-Free Status, unless prior to taking any such action set forth in the foregoing clauses (i) through (vi):

(A) Corner Store shall have requested that Valero obtain a Ruling in accordance with Section 7.04(b) and (d) of this Agreement to the effect that such transaction will not affect the Tax-Free Status and Valero shall have received such a Ruling in form and substance satisfactory to Valero in its sole and absolute discretion, which discretion shall be exercised in good faith solely to preserve the Tax-Free Status (and in determining whether a Ruling is satisfactory, Valero may consider, among other factors, the appropriateness of any underlying assumptions and management’s representations made in connection with such Ruling); or

(B) Corner Store shall provide Valero with an Unqualified Tax Opinion in form and substance satisfactory to Valero in its sole and absolute discretion, which discretion shall be exercised in good faith solely to preserve the Tax-Free Status (and in determining whether an opinion is satisfactory, Valero

Each Company shall preserve and keep all Tax Records exclusively relating to the assets and activities of its Group for Pre-Deconsolidation Periods, and Valero shall preserve and keep all other Tax Records relating to Taxes of the Groups for Pre-Deconsolidation 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 (i) the expiration of any applicable statutes of limitations, or (ii) seven years after the Deconsolidation Date (such later date, the “Retention Date”). After the

Retention Date, each Company may dispose of such Tax Records provided that the other Company has not requested in writing within 30 days following the Retention Date the opportunity to copy or remove all or any part of such Tax Records. Upon such written request, the requesting Company shall have the opportunity, at its cost and expense, to copy or remove, within 30 days of such request, all or any part of such Tax Records and the other Company may dispose of Such Tax Records following such 30 day period. 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 9 are no longer material in the administration of any matter under the Code or other applicable Tax Law and the other Company agrees in writing, then such first Company may dispose of such Tax Records upon 90 days’ prior written notice to the other Company. Any notice of an intent to dispose given pursuant to this Section 9.01 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, Corner Store determines to decommission or otherwise discontinue any computer program or information technology system used to access or store any Tax Records, then Corner Store may decommission or discontinue such program or system upon 90 days’ prior written notice to Valero and Valero 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 9.02 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 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, and in all events subject to such reasonable requirements as the providing party’s information technology department may impose to ensure compliance with such party’s data protection policies.

Section 10.01 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 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. If an indemnified party has knowledge of an asserted Tax liability with respect to a matter for which it is to be indemnified hereunder and such party fails to give the indemnifying party prompt notice of such

asserted Tax liability and the indemnifying party is entitled under this Agreement to contest the asserted Tax liability, then (i) if the indemnifying party is precluded from contesting the asserted Tax liability in any forum as a result of the failure to give prompt notice, the indemnifying party shall have no obligation to indemnify the indemnified party for any Taxes arising out of such asserted Tax liability, and (ii) if the indemnifying party is not precluded from contesting the asserted Tax liability in any forum, but such failure to give prompt notice results in a material monetary detriment to the indemnifying party, then any amount which the indemnifying party is otherwise required to pay the indemnified party pursuant to this Agreement shall be reduced by the amount of such detriment.

Section 10.02 Control of Tax Contests.

(a) Separate Company Taxes.

The “Tax Contest Committee” shall be comprised of two persons, one person selected by Valero (as designated in writing to Corner Store) and one person selected by Corner Store (as designated in writing to Valero). Each person serving on the Tax Contest Committee shall continue to serve unless and

until he or she is replaced by the party designating such person.

(f) Settlement Rights. The Controlling Party shall have the sole right to contest, litigate, compromise and settle any 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 a 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 6) to the Controlling Party under this Agreement: (i) 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; (ii) 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; (iii) 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; (iv) the Controlling Party shall consult with the Non-Controlling Party and offer the Non-Controlling Party a reasonable opportunity to comment before submitting any written materials prepared or furnished in connection with such potential adjustment in such Tax Contest; and (v) the Controlling Party shall defend such Tax Contest diligently and in good faith.

In the case of any Tax Contest described in Section 10.02(a), (b), (c) or (d), “Controlling Party” means the Company entitled to control the Tax Contest under such Section and “Non-Controlling Party” means the other Company. In the case of any Tax Contest described in Section 10.02(i), “Controlling Party” means Valero and “Non-Controlling Party” means Corner Store.

The failure of the Controlling Party to provide any notice specified in this Section 10.02(g) 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 actually 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.

Any payments pursuant to such agreements shall be disregarded for purposes of computing amounts due under this Agreement; provided that to the extent appropriate, as determined by Valero, payments made pursuant to such agreements shall be credited to Corner Store or Valero, respectively, in computing their respective obligations pursuant to this Agreement, in the event that such payments relate to a Tax liability that is the subject matter of this Agreement for a Tax Period that is the subject matter of this Agreement.

Section 12. Survival of Obligations. The representations, warranties, covenants and agreements set forth in this Agreement shall be unconditional and absolute and shall remain in effect without limitation as to time.

Section 13. Treatment of Payments; Tax Gross Up.

Section 13.01 Treatment of Tax Indemnity and Tax Benefit Payments. In the absence of any change in Tax treatment under the Code or other applicable Tax Law,

(a) any Tax indemnity payments made by a Company under Section 5 shall be reported for Tax purposes by the payor and the recipient as distributions or capital contributions, as appropriate, occurring immediately before the Deconsolidation (but only to the extent the payment does not relate to a Tax allocated to the payor in accordance with Section 1552 of the Code or the regulations thereunder or Treasury Regulation Section 1.1502-33(d) (or under corresponding principles of other applicable Tax Laws)) or as payments of an assumed or retained liability, and

(b) any Tax Benefit payments made by a Company under Section 6, shall be reported for Tax purposes by the payor and the recipient as distributions or capital contributions, as

appropriate, occurring immediately before the Deconsolidation (but only to the extent the payment does not relate to a Tax allocated to the payor in accordance with Section 1552 of the Code or the regulations thereunder or Treasury Regulation Section 1.1502-33(d) (or under corresponding principles of other applicable Tax Laws)) or as payments of an assumed or retained liability.

Section 13.02 Tax Gross Up. If notwithstanding the manner in which Tax indemnity payments and Tax Benefit payments were reported, there is an adjustment to the Tax liability of a Company as a result of its receipt of a payment pursuant to this Agreement, such payment shall be appropriately adjusted so that the amount of such payment, reduced by the amount of all Income Taxes payable with respect to the receipt thereof (but taking into account all correlative Tax Benefits resulting from the payment of such Income Taxes), shall equal the amount of the payment which the Company receiving such payment would otherwise be entitled to receive pursuant to this Agreement.

Section 13.03 Interest Under This Agreement. Anything herein to the contrary notwithstanding, to the extent one Company (“Indemnitor”) makes a payment of interest to another Company (“Indemnitee”) under this Agreement with respect to the period from the date that the Indemnitee made a payment of Tax to a Tax Authority to the date that the Indemnitor reimbursed the Indemnitee for such Tax payment, the interest payment shall be treated as interest expense to the Indemnitor (deductible to the extent provided by law) and as interest income by the Indemnitee (includible in income to the extent provided by law). The amount of the payment shall not be adjusted under Section 2.02 to take into account any associated Tax Benefit to the Indemnitor or increase in Tax to the Indemnitee.

Section 14. Disagreements. The Companies mutually desire that friendly collaboration will continue between them. Accordingly, they will try, and they will cause their respective Group members to try, to resolve in an amicable manner all disagreements and misunderstandings connected with their respective rights and obligations under this Agreement, including any amendments hereto. In furtherance thereof, in the event of any dispute or disagreement (other than a High-Level Dispute) (a “Tax Advisor Dispute”) between any member of the Valero Group and any member of the Corner Store Group as to the interpretation of any provision of this Agreement or the performance of obligations hereunder, the Tax departments of the Companies shall negotiate in good faith to resolve the Tax Advisor Dispute. If such good faith negotiations do not resolve the Tax Advisor Dispute, then the matter, upon written request of either Company, will be referred for resolution to executives who hold, at a minimum, the office of Senior Vice President and/or General Counsel (the “Senior Executives”), which executives will make a good faith effort to resolve the Tax Advisor Dispute pursuant to the procedures set forth in Section 4.2 of the Separation and Distribution Agreement. If the Senior Executives do not agree to a resolution of a Tax Advisor Dispute within thirty (30) days after the reference of the Tax Advisor Dispute to it, then the matter will be referred to a Tax Advisor acceptable to each of the Companies. The Tax Advisor may, in its discretion, obtain the services of any third-party appraiser, accounting firm or consultant that the Tax Advisor deems necessary to assist it in resolving such disagreement. The Tax Advisor shall furnish written notice to the Companies of its resolution of any such Tax Advisor Dispute as soon as practical, but in any event no later than 45 days after its acceptance of the matter for resolution. Any such resolution by the Tax Advisor will be conclusive and binding on the Companies. Following receipt of the

Tax Advisor’s written notice to the Companies of its resolution of the Tax Advisor Dispute, the Companies shall each take or cause to be taken any action necessary to implement such resolution of the Tax Advisor. In accordance with Section 16, each Company shall pay its own fees and expenses (including the fees and expenses of its representatives) incurred in connection with the referral of the matter to the Tax Advisor. All fees and expenses of the Tax Advisor in connection with such referral shall be shared equally by the Companies. Any High-Level Dispute shall be resolved pursuant to the procedures set forth in Section 4.3 of the Separation and Distribution Agreement. Nothing in this Section 14 will prevent either Company from seeking injunctive relief if any delay resulting from the efforts to resolve the Tax Advisor Dispute through the Senior Executives and the Tax Advisor (or any delay resulting from the efforts to resolve any High-Level Dispute through the procedures set forth in Section 7.3 of the Separation and Distribution Agreement) could result in serious and irreparable injury to either Company. Notwithstanding anything to the contrary in this Agreement, the Separation and Distribution Agreement or any Ancillary Agreement, Valero and Corner Store are the only members of their respective Group entitled to commence a dispute resolution procedure under this Agreement, and each of Valero and Corner Store will cause its respective Group members not to commence any dispute resolution procedure other than through such party as provided in this Section 14.

Section 15. Late Payments. Any amount owed by one party to another party under this Agreement which is not paid when due shall bear interest at the Prime Rate plus two percent, compounded semiannually, from the due date of the payment to the date paid. To the extent interest required to be paid under this Section 15 duplicates interest required to be paid under any other provision of this Agreement, interest shall be computed at the higher of the interest rate provided under this Section 15 or the interest rate provided under such other provision.

Section 16. Expenses. Except as otherwise provided in this Agreement, each party and its Affiliates shall bear their own expenses incurred in connection with preparation of Tax Returns, Tax Contests, and other matters related to Taxes under the provisions of this Agreement.

Section 17. General Provisions.

A written waiver given for one matter or occasion is effective only in that instance and only for the purpose stated.

Unless otherwise indicated, all “Section” references in this Agreement are to sections of this Agreement.

Section 17.09 No Double Recovery. No provision of this Agreement shall be construed to provide an indemnity or other recovery for any costs, damages, or other amounts for which the damaged party has been fully compensated under any other provision of this Agreement or under any other agreement or action at law or equity. Unless expressly required in this Agreement, a party shall not be required to exhaust all remedies available under other agreements or at law or equity before recovering under the remedies provided in this Agreement.

The parties may execute this Agreement in multiple counterparts, each of which constitutes an original as against the party that signed it, and all of which together constitute one agreement. This Agreement is effective upon delivery of one executed counterpart from each party to the other party. The signatures of the parties need not appear on the same counterpart. The delivery of signed counterparts by facsimile or email transmission that includes a copy of the sending party’s signature is as effective as signing and delivering the counterpart in person.

Section 17.12 Jurisdiction. If any dispute arises out of or in connection with this Agreement, except as expressly contemplated by another provision of this Agreement, the parties irrevocably (and the parties will cause each other member of their respective Group to irrevocably) (a) consent and submit to the exclusive jurisdiction of federal and state courts located in San Antonio, Texas, (b) waive any objection to that choice of forum based on venue or to the effect that the forum is not convenient, and (c) WAIVE TO THE FULLEST EXTENT PERMITTED BY LAW ANY RIGHT TO TRIAL OR ADJUDICATION BY JURY.
