Subject to the limitations set forth in this Article 6, CAPL shall indemnify, defend and hold CST and its affiliates (other than CAPL and its subsidiaries) and its respective securityholders, directors, officers and employees (the “CST Indemnified Parties”) harmless from and against any and all damages suffered or incurred by the CST Indemnified Parties as a result of or arising out of (a) any inaccuracy, violation or breach of a representation or warranty of CAPL in this Agreement or (b) any breach of any other agreement or covenant on the part of CAPL made under this Agreement.

6.3Tax Indemnification. CST will indemnify, defend and hold the CAPL Indemnified Parties harmless from and against any and all damages suffered or incurred by any CAPL Indemnified Party for (a) any taxes with respect to the operations of CSTMS on or prior to the Closing Date and (b) CSTMS’s obligation to pay any taxes of any person (other than taxes of CAPL and its subsidiaries) under Treasury Regulations Section 1.1502-6 (or any similar provision of state, local or foreign law), as a transferee or successor, by contract or otherwise.

6.4Survival.

(a)All the provisions of this Agreement shall survive the date hereof, provided that the representations and warranties set forth in Articles 2 and 3 shall terminate on the first anniversary of the date of this Agreement, except (i) the representations and warranties of CST set forth in Section 2.7 and the covenants of CST set forth in Section 6.3 shall survive until 30 days after the expiration of the applicable statutes of limitations (including all periods of extension and tolling), (ii) the representations and warranties of CST set forth in Sections 2.1, 2.2, 2.4, 2.5 and 2.12 (collectively, the “CST Fundamental Representations”) shall survive forever and (iii) the representations and warranties of CAPL set forth in Sections 3.1, 3.2 and 3.4 shall survive forever. After a representation and warranty or agreement or covenant has terminated and expired, no indemnification shall or may be sought pursuant to Sections 6.1 or 6.2 by any person or entity who would have been entitled pursuant to this Article 6 to indemnification on the basis of such representation and warranty or agreement or covenant prior to its termination and expiration, provided that in the case of each representation and warranty or covenant or agreement that shall terminate and expire as provided in this Section 6.4, no claim presented in writing for indemnification pursuant to this Article 6 on the basis of such representation and warranty or agreement or covenant prior to its termination and expiration shall be affected in any way by that termination and expiration. Except as otherwise provided in this Section 6.4, the covenants and agreements entered into pursuant to this Agreement shall survive the date hereof in accordance with their terms (or, in the absence of a stated term, in perpetuity).

(b)The indemnification obligations under this Article 6 or elsewhere in this Agreement shall apply regardless of whether any suit or action results solely or in part from the active, passive or concurrent negligence or strict liability of the indemnified party.

6.5Demands.

(a)Each indemnified party hereunder agrees that promptly upon its discovery of facts giving rise to a claim for indemnity under the provisions of this Agreement, including receipt by it of notice of any demand, assertion, claim, action or proceeding, judicial or otherwise, by any third party (such claims for indemnity involving third party claims being, collectively, referred to herein as the “Indemnity Claim”), with respect to any matter as to which it claims to be entitled to indemnity under the provisions of this Agreement, it will give prompt notice thereof in writing to the indemnifying party (a “Claim Notice”), together with a detailed statement of such information respecting any of the foregoing as it shall have and all supporting evidence, including any damages already incurred and its detailed estimate of any damages to be incurred in the future. Such notice shall include a formal demand for indemnification under this Agreement.

(b)If the indemnified party knowingly failed to notify the indemnifying party thereof in accordance with the provisions of this Agreement in sufficient time to permit the indemnifying party or its counsel to defend against an Indemnity Claim and to make a timely response thereto, the indemnifying party’s indemnity obligation relating to such Indemnity Claim shall be limited to the extent that such failure has actually prejudiced or damaged the indemnifying party with respect to that Indemnity Claim.

(c)With respect to any claim for indemnification not involving an Indemnity Claim, the indemnifying party shall be deemed to have agreed to indemnify the indemnified party pursuant to this Article 6 with respect to the claims set forth in any Claim Notice if and to the extent the indemnifying party does not provide the indemnified party notice of its disagreement with respect to the contents of a Claim Notice within 30 calendar days of receipt thereof.

6.6Right to Contest and Defend.

(a)The indemnifying party shall be entitled, at its cost and expense, to contest and defend by all appropriate legal proceedings any Indemnity Claim for which it is called upon to indemnify by the indemnified party under the provisions of this Agreement; provided, that notice of the intention to so contest shall be delivered by the indemnifying party to the indemnified party within 20 days from the date of receipt by the indemnifying party of notice by the indemnified party of the assertion of the Indemnity Claim. Any such contest may be conducted in the name and on behalf of the indemnifying party or the indemnified party as may be appropriate. Such contest shall be conducted by reputable counsel employed by the indemnifying party and not reasonably objected to by the indemnified party, but the indemnified party shall have the right but not the obligation to participate in such proceedings and to be represented by counsel of its own choosing at its sole cost and expense.

(b)The indemnifying party shall have full authority to determine all action to be taken with respect thereto; provided, however, that the indemnifying party will not have the authority to subject the indemnified party to any obligation whatsoever, other than the performance of purely ministerial tasks or obligations not involving material expense or injunctive relief. If the indemnifying party does not elect to contest any such Indemnity Claim, the indemnifying party shall be bound by the result obtained with respect thereto by the indemnified party. If the indemnifying party assumes the defense of an Indemnity Claim, the indemnified party shall agree to any settlement, compromise or discharge of an Indemnity Claim that the indemnifying party may recommend and that by its terms obligates the indemnifying party to pay the full amount of the liability in connection with such Indemnity Claim, which releases the indemnified party completely in connection with such Indemnity

Claim and which would not otherwise adversely affect the indemnified party as reasonably determined by the indemnified party.

(c)Notwithstanding the foregoing, the indemnifying party shall not be entitled to assume the defense of any Indemnity Claim (and shall be liable for the reasonable fees and expenses of counsel incurred by the indemnified party in defending such Indemnity Claim) if the Indemnity Claim seeks an order, injunction or other equitable relief or relief for other than money damages against the indemnified party which the indemnified party reasonably determines, after conferring with its outside counsel, cannot be separated from any related claim for money damages. If such equitable relief or other relief portion of the Indemnity Claim can be so separated from that for money damages, the indemnifying party shall be entitled to assume the defense of the portion relating to money damages.

6.7Cooperation. If requested by the indemnifying party, the indemnified party agrees to cooperate with the indemnifying party and its counsel in contesting any Indemnity Claim that the indemnifying party elects to contest or, if appropriate, in making any counterclaim against the person asserting the Indemnity Claim, or any cross-complaint against any person, and the indemnifying party will reimburse the indemnified party for any expenses incurred by it in so cooperating without regard to any limitations set forth in Section 6.10. At no cost or expense to the indemnified party, the indemnifying party shall cooperate with the indemnified party and its counsel in contesting any Indemnity Claim.

6.8Right to Participate. The indemnified party agrees to afford the indemnifying party and its counsel the opportunity to be present at, and to participate in, conferences with all persons, including governmental authorities, asserting any Indemnity Claim against the indemnified party or conferences with representatives of or counsel for such persons.

6.9Payment of Damages. The indemnification required hereunder shall be made by periodic payments of the amount thereof during the course of the investigation or defense, within 10 days as and when reasonably specific bills are received or damages are incurred and reasonable evidence thereof is delivered. In calculating any amount to be paid by an indemnifying party by reason of the provisions of this Agreement, the amount shall be reduced by all insurance proceeds received and any indemnification reimbursement proceeds received from third parties.

6.10Limitations on Indemnification.

(a)In no event shall CST’s aggregate liability to the CAPL Indemnified Parties under Section 6.1 exceed an amount equal to 20% of the dollar value of the Consideration as of the Closing Date (the “Ceiling Amount”). Notwithstanding the foregoing, the Ceiling Amount shall not apply to inaccuracies, violations or breaches of any of the CST Fundamental Representations, provided CST’s aggregate liability for a breach of representations hereunder (including the CST Fundamental Representations) shall not exceed an amount equal to the dollar value of the Consideration as of the Closing Date.

(b)In no event shall CAPL’s aggregate liability to the CST Indemnified Parties under Section 6.2 exceed the Ceiling Amount. Notwithstanding the foregoing, the Ceiling Amount shall not apply to inaccuracies, violations or breaches of any of the representations and warranties contained in Sections 3.1, 3.2 and 3.4 (the “CAPL Fundamental Representations”), provided CAPL’s aggregate liability for a breach of representations hereunder (including the CAPL Fundamental Representations) shall not exceed an amount equal to the dollar value of the Consideration as of the Closing Date.

(c)Sole Remedy. Following the Closing, no Party shall have any liability under this Agreement or the transactions contemplated hereby or thereby except as is provided in this Article 6 (other than claims or causes of action arising from actual fraud).

7.1Costs. CST shall pay all expenses, fees and costs, including sales, use and similar taxes arising out of the transactions contemplated by this Agreement and shall pay all documentary, filling, recording, transfer and conveyance taxes and fees required in connection therewith.

7.2Headings; References; Interpretation. All Article and Section headings in this Agreement are for convenience only and shall not be deemed to control or affect the meaning or construction of any of the provisions of this Agreement. The words “hereof,” “herein,” and “hereunder” and words of similar import, when used in this Agreement, shall refer to this Agreement as a whole, and not to any particular provision of this Agreement. All personal pronouns used in this Agreement, whether used in the masculine, feminine or neuter gender, shall include all genders, and the singular shall include the plural and vice versa. The use in this Agreement of the word “including” shall mean “including without limitation.”

7.3No Third Party Rights. The provisions of this Agreement are intended to bind the Parties as to each other and are not intended to and do not create rights in any other person or confer upon any other person any benefits, rights or remedies, and no person is or is intended to be a third party beneficiary of any of the provisions of this Agreement, except in each case to the extent of indemnification obligations in Article 6.

7.4Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the Parties and their respective successors and assigns.

7.5Governing Law; Venue. This Agreement shall be construed in accordance with and governed by the laws of the State of Delaware, without regard to the principles of conflicts of law. EACH OF THE PARTIES IRREVOCABLY AND UNCONDITIONALLY AGREES TO (a) BE SUBJECT TO THE JURISDICTION OF THE COURTS OF THE STATE OF DELAWARE AND OF THE FEDERAL COURTS SITTING IN THE STATE OF DELAWARE, AND (b) TO THE EXTENT THAT SUCH PARTY IS NOT OTHERWISE SUBJECT TO SERVICE OF PROCESS IN THE STATE OF DELAWARE, TO APPOINT AND MAINTAIN AN AGENT FOR ACCEPTANCE OF LEGAL PROCESS IN THE STATE OF DELAWARE AND TO NOTIFY THE OTHER PARTY OF THE NAME AND ADDRESS OF SUCH AGENT.

7.6Severability. If any of the provisions of this Agreement are held by any court of competent jurisdiction to contravene, or to be invalid under, the laws of any political body having jurisdiction over the subject matter of this Agreement, such contravention or invalidity shall not invalidate the entire Agreement. Instead, this Agreement shall be construed as if it did not contain the particular provision or provisions held to be invalid and an equitable adjustment shall be made and necessary provision added so as to give effect to the intention of the Parties as expressed in this Agreement as of the time of execution of this Agreement.

7.7Amendment, Modification and Termination. This Agreement may be amended or modified from time to time only by the written agreement of the Parties. Each such instrument shall be reduced to writing and shall be designated on its face as an amendment to this Agreement.

7.8Entire Agreement. This Agreement and the instruments referenced herein supersede all previous understandings of or agreements between the Parties, whether oral or written, with respect to the subject matter of this Agreement and such instruments. This Agreement and such instruments contain the entire agreement and understanding of the Parties with respect to the subject matter of this Agreement and such instruments. There are no unwritten oral agreements between the Parties. No understanding, representation, promise or agreement, whether oral or written, is intended to be or shall be included in or form a part of this Agreement unless it is contained in a written amendment to this Agreement executed by the Parties after the date of this Agreement.

7.9Specific Performance. The Parties acknowledge that, in view of the uniqueness of the transactions contemplated by this Agreement, the Parties will not have an adequate remedy at law for monetary damages and will be irreparably damaged in the event that Closing fails to occur, or is rendered incapable of occurring, as a result the other Party’s breach of any term of this Agreement; and, therefore, the Parties agree that each Party shall be entitled to specific enforcement of the terms of this Agreement to compel the other Party to consummate the transactions contemplated by this Agreement, subject to the terms and conditions of this Agreement.

IN WITNESS WHEREOF, the Parties to this Agreement have caused it to be duly executed as of the date first above written.
