	 	(a)	The purchase price to be paid for the Membership Interests shall be paid as provided in Section 1.2 and shall be the aggregate of (i) $16,500,058.31 in cash (the “Cash Consideration”),

	 	(i)	offer, pledge, sell, contract to sell, grant any option or contract to purchase, purchase any option or contract to sell, grant any right or warrant to purchase, lend or otherwise transfer, encumber or dispose of all or
any portion of the Equity Consideration to be received by such IDR Seller; or 

  

	 	(ii)	enter into any swap or other agreement, arrangement or transaction that transfers to another, in whole or in part, any of the economic consequences of ownership of the Equity Consideration to be received by such IDR
Seller; 

 whether any transaction described in clause (i) or (ii) above is to be settled by delivery of all or any portion of the
Equity Consideration, other securities, in cash or otherwise; provided, however, that commencing on the day after the Lock-up Period ends, the IDR Sellers may make sales of all or any portion of the Equity Consideration, in compliance
with and pursuant to the provisions of Rule 144 promulgated under the Securities Act of 1933, as amended (the “Securities Act”). 
  

	 	(b)	Subject to Section 1.4(a) above, each IDR Seller further agrees that CST may, with respect to all or any portion of the Equity Consideration, cause CST’s transfer agent or other registrar to enter stop
transfer instructions and implement stop transfer procedures with respect to such securities during the Lock-up Period.

representation to the date of this Agreement or another specified date), each of the IDR Sellers hereby represents and warrants to CST and the IDR Buyer, except as disclosed in the Schedules hereto (which Schedules shall serve to qualify the
correspondingly numbered section or subsection of this Agreement and any other section or subsection of this Agreement to the extent the applicability of such disclosure to such other section or subsection is reasonably apparent on its face to the
non-disclosing party), as follows:

 4

and conditions thereunder. As of the Closing Date, the execution and delivery of such other Transaction Documents and the performance by the IDR Sellers of their obligations thereunder will have been duly authorized by the trustee or other governing
body of each of the IDR Sellers, if applicable, and no other proceedings on the part of any of the IDR Sellers will be necessary to authorize such execution, delivery and performance. At or prior to the Closing, the other Transaction Documents to
which any of the IDR Sellers is party will be duly executed and delivered by such IDR Seller and will constitute such IDR Seller’s valid and binding obligation enforceable against such IDR Seller in accordance with its terms, except as
enforcement may be limited by the Enforceability Exceptions. 

  

	Section 2.3	No Conflict or Violation. 

 Except as set forth in Schedule 2.3, the execution, delivery
and performance of this Agreement and the other Transaction Documents to which each of the IDR Sellers is a party does not and will not: (a) violate or conflict with any provision of the Organizational Documents of any IDR Seller or the

Material Adverse Effect. 
  

	Section 2.4	Consents and Approvals. 

 Except (a) as disclosed on Schedule 2.4 or (b) as would
not reasonably be expected to have a Seller Material Adverse Effect, the IDR Sellers’ execution and delivery of this Agreement or the other Transaction Documents to which any of the IDR Sellers is party or performance of their respective
obligations hereunder or thereunder, does not require the consent, approval, waiver or authorization of, or filing, registration or qualification with, any Person by any of the IDR Sellers. 

 

	Section 2.5	Ownership of IDRs. 

 As of the Execution Date, the IDR Sellers are, and as of the Closing Date, as
a result of the Pre-Closing Contributions, the IDR Holders will be, the sole record and (together with the IDR Sellers) beneficial owners of, and have valid title to, the IDRs respectively held by each of them, free and clear of any Encumbrances
except for (a) restrictions on transfer arising under applicable securities Laws, (b) matters described on Schedule 2.5, if any, and (c) applicable terms and conditions of the Partnership Agreement. The IDRs have been duly
authorized and validly issued in accordance with the Partnership Agreement and are fully paid (to the extent required by the Partnership Agreement) and nonassessable (except as such nonassessability may be affected by Sections 17-303, 17-607 and
17-804 of the Delaware Revised Uniform Limited Partnership Act). Other than this Agreement, there are no outstanding options, warrants or similar rights to purchase or acquire from the IDR Sellers or IDR Holders any of the IDRs. Other than the IDRs
being indirectly conveyed to IDR Buyer pursuant to the terms of this Agreement, no other IDRs have been issued by the Partnership to any Person. 
  

	Section 2.6	Capitalization of the IDR Holders. 

 As of the Closing, as a result of the Pre-Closing
Contributions, (a) Topper Trust will be the sole member of and the sole record and beneficial owner of, and will have valid title to, 100% of the Membership Interests in IDR LLC I and (b) Reilly Trust will be the sole member of and the
sole record and beneficial owner of, and will have valid title to, 100% of the Membership Interests in IDR LLC II, in each case free and clear of any Encumbrances except for restrictions on transfer arising under applicable securities Laws. As of
the Closing, the Membership Interests will have been duly authorized and validly issued and will be fully paid and nonassessable (except as such nonassessability may be affected by Sections 18-303, 18-607 and 18-804 of the Delaware Limited Liability
Company Act). There are no preemptive or other rights to subscribe for or to purchase, and no restriction upon the voting or transfer of, any interest in either IDR Holder. Other than this Agreement, as of the Closing, there shall be no outstanding
options, warrants or similar rights to purchase or acquire from the IDR Sellers any equity interests in either IDR Holder. As of the Closing, none of the IDR Holders shall have any outstanding bonds, debentures, notes or other obligation the holders
of which have the right to vote (or are convertible into or exercisable for securities having the right to vote) with the holders of Membership Interests in either IDR Holder. As of the Closing, the IDR Sellers shall have delivered true, correct and
complete copies of all of the Organizational Documents of each IDR Holder to the IDR Buyer. 

  
 5 

	Section 2.7	Litigation. 

 There are no Legal Proceedings pending or, to the Knowledge of the IDR Sellers,
threatened against or involving the IDR Sellers or IDR Holders that, individually or in the aggregate, would reasonably be expected to have a Seller Material Adverse Effect, and there is no order, judgment, injunction or decree of any Governmental
Authority outstanding against any of the IDR Sellers or IDR Holders that, individually or in the aggregate, would reasonably be expected to have a Seller Material Adverse Effect. “Legal Proceeding” shall mean any judicial or
administrative suits, proceedings (public or private), claims or investigations before any Governmental Authority or arbitral actions. 
  

	Section 2.8	Solvency. 

 Each of the IDR Sellers is, and immediately after giving effect to the transactions
contemplated by this Agreement and the Transaction Documents will be, Solvent. “Solvent” means, on any date of determination, that on such date (a) the fair value of the property of such IDR Seller is greater than the total
amount of liabilities, including, without limitation, contingent liabilities, of such IDR Seller that would constitute liabilities under GAAP, (b) the present fair equivalent value of the assets of such IDR Seller is not less than the amount
that will be required to pay its debts as they become absolute and matured, taking into account the possibility of refinancing such obligations and selling assets, (c) such IDR Seller does not intend to, and does not believe that it will, incur
debts or liabilities beyond such party’s ability to pay such debts as they mature taking into account the possibility of refinancing such obligations and selling assets and (d) such IDR Seller is not engaged in business or a transaction,
and does not intend to engage in business or a transaction, for which such party’s property remaining after such transaction would constitute unreasonably small capital. 
  

	Section 2.9	Brokers. 

 No broker, investment banker, financial advisor or other Person, other than Barclays
Capital Inc. (the fees and expenses of which will be borne by LGC, except as provided in Section 8.3), is entitled to any broker’s, finder’s, financial advisor’s or other similar fee or commission in connection with this
Agreement or any of the transactions contemplated by this Agreement based upon arrangements made by or on behalf of any IDR Seller or IDR Holder.

Article VI 
 TERMINATION

  

	Section 6.1	Termination of Agreement. 

  

	 	(a)	This Agreement may be terminated and the transactions contemplated by this Agreement may be abandoned at any time before the Closing as follows: 

 

	 	(i)	by the mutual written agreement of the Parties; 

  

	 	(ii)	by the IDR Sellers, upon joint written notice to CST and the IDR Buyer, if there has been a Breach on the part of CST or IDR Buyer, which Breach, either individually or in the aggregate, would result in, if occurring or
continuing on the Closing Date, the failure of the conditions set forth in Section 5.3(c) or Section 5.3(d), and such Breach is incapable of being cured, or if capable of being cured, has not been cured within thirty
(30) days following receipt by CST and IDR Buyer of a Notification of such Breach from the IDR Sellers. 

  

	 	(i)	by CST or the IDR Buyer, upon written notice to the IDR Sellers, if there has been a Breach on the part of any IDR Seller, which Breach, either individually or in the aggregate, would result in, if occurring or
continuing on the Closing Date, the failure of the conditions set forth in Section 5.2(c) or Section 5.2(d), and such Breach is incapable of being cured, or if capable of being cured, has not been cured within thirty
(30) days following receipt by the IDR Sellers of a Notification of such Breach from CST or the IDR Buyer; or 

  

	 	(ii)	by any Party, upon written notice to the other Parties, if the transactions contemplated by this Agreement have not been consummated on or before November 1, 2014 (the “Outside Date”);
provided, however, that (i) IDR Sellers may not terminate this Agreement pursuant to this Section 6.1(a)(iv) if such failure to consummate is due to the failure of any IDR Seller to perform or observe in all material
respects the covenants and agreements of this Agreement to be performed or observed by such IDR Seller and (ii) CST and IDR Buyer may not terminate this Agreement pursuant to this Section 6.1(a)(iv) if such failure to consummate is
due to the failure of CST or IDR Buyer to perform or observe in all material respects the covenants and agreements of this Agreement to be performed or observed by CST or IDR Buyer. 

 

	 	(b)	This Agreement shall automatically terminate and the transactions contemplated by this Agreement shall be abandoned if the GP Purchase Agreement is terminated pursuant to Article VII of the GP Purchase Agreement.

  
 15 

	Section 6.2	Effect of Termination. 

 In the event of termination of this Agreement pursuant to this Article
VI, all rights and obligations of the Parties under this Agreement shall terminate, except the provisions of Section 4.6 (Confidential Information), Article VI (Termination), Article VIII (Miscellaneous Provisions) and
Article IX (Definitions) shall survive such termination; provided, however, that nothing in this Agreement shall relieve any Party from any liability for any intentional or willful and material Breach by such Party and all
rights and remedies of a non-breaching Party under this Agreement in the case of such intentional or willful and material Breach, whether arising at law or in equity, shall be preserved. 

 

	Section 6.3	Specific 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 any
other Party’s Breach of any term of this Agreement; and, therefore, the Parties agree that each Party, as the case may be, shall be entitled to specific enforcement of the terms of this Agreement to compel the other Parties, as the case may be,
to consummate the transactions contemplated by this Agreement, subject to the terms and conditions of this Agreement. 
 Article VII

	Section 7.1	Survival. 

  

	 	(a)	The representations and warranties of the IDR Sellers contained in this Agreement or in any certificates or other documents delivered pursuant to this Agreement on the Closing Date shall survive the Closing for a period
of twelve (12) months following the Closing Date, at which time such representations or warranties will terminate and no indemnification obligations or any other action, claim or proceeding will be associated therewith, based thereon or
otherwise brought, claimed or noticed following such termination; provided, however, that the representations and warranties set forth in Section 2.1 (Organization; Qualification), Section 2.2 (Validity of

twelve (12) months following the Closing Date, at which time such representations or warranties will terminate and no indemnification obligations or any other action, claim or proceeding will be associated therewith, based thereon or otherwise

Authorization), Section 3.5 (Brokers) and Section 3.8 (Share Issuance) shall survive indefinitely (collectively, the “Buyer Fundamental Representations”).

performed. All covenants and agreements that by their terms are to be performed in their entirety prior to the Closing shall terminate at the Closing. 

  

	Section 7.2	Indemnification. 

  

	 	(a)	From and after the Closing, the Topper Trust shall indemnify and defend, save and hold the Buyer Indemnified Parties harmless if any such Buyer Indemnified Party shall suffer any damage, judgment, fine, penalty, demand,
settlement, liability, loss, cost, Tax, expense (including reasonable attorneys’, consultants’ and experts’ fees), claim or cause of action (each, a “Loss,” and collectively, “Losses”) arising out of,
relating to or resulting from: 

  

	 	(i)	any breach or inaccuracy in any representation or warranty by any IDR Seller contained in this Agreement or any certificates or other documents delivered by any IDR Seller pursuant to this Agreement at the Closing;

  

	 	(ii)	any failure by any IDR Seller to perform or observe any term, provision, covenant or agreement on the part of the IDR Sellers to be performed or observed under this Agreement; 

  
 16 

	 	(iii)	IDR Sellers’ Taxes and Pre-Closing IDR Distribution Claims;

	 	(b)	From and after the Closing, CST and the IDR Buyer shall, jointly and severally, indemnify and defend, save and hold the Seller Indemnified Parties harmless if any such Seller Indemnified Party shall suffer any Loss

	 	(ii)	any failure by CST or IDR Buyer to perform or observe any term, provision, covenant, or agreement on the part of CST or IDR Buyer to be performed or observed under this Agreement; 

 

	 	(iii)	any broker or other Person claiming to be entitled to an investment banker’s, financial advisor’s, broker’s, finder’s or similar fee or commission in respect of the execution of this Agreement or the

	 	(iv)	any breach by CST or GP Buyer of the GP Purchase Agreement for which LGC would be entitled to indemnification pursuant to the terms and conditions of the GP Purchase Agreement; or 

 

	 	(v)	IDR Buyer’s Taxes. 

  

	 	(c)	In addition to the temporal limitations set forth in Section 7.1, the foregoing indemnification obligations shall be subject to the following limitations: 

 

	 	(i)	the Topper Trust’s and LGC’s cumulative aggregate liability for Losses under Section 7.2(a)(i) and Section 8.2(a)(i) of the GP Purchase Agreement, and CST, IDR Buyer’s and GP Buyer’s
cumulative aggregate liability under Section 7.2(b)(i) and Section 8.2(b)(i) of the GP Purchase Agreement, in each case, shall not exceed $8,500,000 (the “Cap”); provided, however, that the Cap shall
not be applicable to (A) Losses with respect to the Seller Fundamental Representations or the Buyer Fundamental Representations, as applicable, in each case whether made in this Agreement or in the GP Purchase Agreement (B) Losses with
respect to matters that constitute fraud or intentional misrepresentation or (C) Losses with respect to the matters set forth in Section 7.2(a)(iii) and Section 7.2(b)(v); 

 

	 	(ii)	no indemnification for any Losses asserted against the Topper Trust or LGC under Section 7.2(a)(i) or Section 8.2(a)(i) of the GP Purchase Agreement or against CST, IDR Buyer or GP Buyer under
Section 7.2(b)(i) or Section 8.2(b)(i) of the GP Purchase Agreement shall be required unless and until the cumulative aggregate amount of such Losses incurred by the Buyer Indemnified Parties or the Seller Indemnified Parties, in
each case as a group, exceeds $1,000,000 (the “Deductible”), at which point the Topper Trust and LGC shall be obligated to indemnify the Buyer Indemnified Parties or CST, the IDR Buyer and GP Buyer shall be obligated to indemnify
the Seller Indemnified Parties, as the case may be, only for the amount of such Losses in excess of the Deductible; provided, however, that the Deductible shall not be applicable to (A) Losses with respect to the Seller
Fundamental Representations or the Buyer Fundamental Representations, as applicable, in each case whether made in this Agreement or in the GP Purchase Agreement (B) Losses with respect to matters that constitute fraud or intentional
misrepresentation or (C) Losses with respect to the matters set forth in Section 7.2(a)(iii) and Section 7.2 (b)(v); 

  

	 	(iii)	the amount of any Losses suffered by a Seller Indemnified Party or a Buyer Indemnified Party, as the case may be (such party seeking indemnification pursuant to this Article VII, the “Indemnified
Party,” and the other party, the “Indemnifying Party”), shall be reduced by any third-party insurance benefits or third party recoveries actually received, or tax benefits recognizable, by the Indemnified Party with respect
to such Loss (net of costs incurred to recover such insurance benefits and third party recoveries, deductibles and retropremiums); 

  
 17 

	 	(iv)	no claim may be asserted nor may any action be commenced against any Party for Breach, unless written notice of such claim or action is received by the other Party describing in reasonable detail the facts and
circumstances with respect to the subject matter of such claim or action on or prior to the date on which the representation or warranty on which such claim or action is based ceases to survive as set forth in Section 7.1;
provided, however, that, notwithstanding the survival periods set forth in Section 7.1, as to each claim for indemnification under this Agreement regarding a representation or warranty that is validly made before expiration
of such representation or warranty, such claim and associated right to indemnification will not terminate before the final determination and satisfaction of such claim; and 

 

	 	(v)	no Indemnified Party shall be entitled under this Agreement to multiple recovery for the same Losses. 

  

	Section  7.3	Procedures. 

 Any Indemnified Party shall notify the Indemnifying Party (with reasonable detail)
promptly after it becomes aware of facts supporting a claim or action for which indemnification is provided under this Article VII, and shall provide to the Indemnifying Party as soon as practicable thereafter all reasonably available
information and documentation necessary to support and verify any Losses associated with such claim or action. Subject to Section 7.2(c)(iv), the failure to so notify or provide information to the Indemnifying Party shall not relieve the
Indemnifying Party of any liability that it may have to any Indemnified Party, except to the extent that the Indemnifying Party demonstrates that it has been materially prejudiced by the Indemnified Party’s failure to give such notice, in which
case the Indemnifying Party shall be relieved from its obligations under this Agreement to the extent of such material prejudice. The Indemnifying Party shall participate in and defend, contest or otherwise protect the Indemnified Party against any
such claim or action by counsel of the Indemnifying Party’s choice at the Indemnifying Party’s sole cost and expense; provided, however, that the Indemnifying Party shall not make any settlement or compromise without the
prior written consent of the Indemnified Party (which consent shall not be unreasonably withheld, conditioned or delayed) unless the sole relief provided is monetary damages that are paid in full by the Indemnifying Party, there is no admission or
statement of fault or culpability on the part of the Indemnified Party and there is an unconditional release of the Indemnified Party from all liability on any claims that are the subject of such claim or action. The Indemnified Party shall use
commercially reasonable efforts upon the reasonable request of the Indemnifying Party to cooperate with and assist the Indemnifying Party in defending, contesting, or otherwise protecting the Indemnified Party against any suit, action,
investigation, claim or proceeding in connection with which a claim for indemnification is made. The Indemnified Party shall have the right, but not the obligation, to participate at the Indemnified Party’s own expense in the defense thereof by
counsel of the Indemnified Party’s choice; provided, however, that the Indemnifying Party shall pay the fees and expenses of separate counsel for the Indemnified Party if (a) the Indemnifying Party has agreed to pay such fees
and expenses, or (b) counsel for the Indemnifying Party reasonably determines that representation of both the Indemnifying Party and the Indemnified Party by the same counsel would create a conflict of interest. If the Indemnifying Party fails
timely to defend, contest or otherwise protect against such suit, action, investigation, claim or proceeding, the Indemnified Party shall have the right to do so, including, without limitation, the right to make any compromise or settlement thereof,
and the Indemnified Party shall be entitled to recover the entire cost thereof from the Indemnifying Party, including, without limitation, reasonable attorneys’ fees, disbursements and amounts paid as the result of such suit, action,
investigation, claim or proceeding. 
  

	Section  7.4	No Speculative Damages. 

 NOTWITHSTANDING ANY PROVISION OF THIS AGREEMENT TO THE CONTRARY, IN NO
EVENT SHALL ANY PARTY TO THIS AGREEMENT BE LIABLE TO ANY OTHER PARTY OR ANY INDEMNIFIED PARTY FOR ANY LOSSES THAT CONSTITUTE SPECIAL, CONSEQUENTIAL, INCIDENTAL OR OTHER INDIRECT DAMAGES OR ANY PUNITIVE OR EXEMPLARY DAMAGES ARISING OUT OF OR IN
CONNECTION WITH THIS AGREEMENT (INCLUDING ANY BREACH OR ALLEGED BREACH OF ANY REPRESENTATION, WARRANTY, COVENANT OR AGREEMENT IN THIS AGREEMENT), WHETHER SUCH LOSSES ARE BASED ON BREACH OF CONTRACT, TORT (INCLUDING NEGLIGENCE) OR OTHER THEORY OF
LIABILITY, INCLUDING DIMINUTION OF VALUE OR LOSSES DETERMINED AS A MULTIPLE OF INCOME; PROVIDED, HOWEVER, THAT THIS SECTION 7.4 SHALL NOT LIMIT AN INDEMNIFIED PARTY’S RIGHT TO RECOVERY HEREUNDER FOR ANY SUCH LOSSES TO THE EXTENT
SUCH INDEMNIFIED PARTY IS REQUIRED TO PAY SUCH LOSSES TO A THIRD PARTY IN CONNECTION WITH A MATTER FOR WHICH SUCH INDEMNIFIED PARTY IS OTHERWISE ENTITLED TO INDEMNIFICATION HEREUNDER. 

  
 18 

	Section  7.5	Remedy. 

 The Parties agree that equitable relief for matters arising under this Agreement after
Closing is only available to the extent provided for in Section 4.6(b) or in Section 8.10. Except for actions involving fraud or intentional misrepresentation, and for equitable relief as provided in the preceding sentence,
from and after the Closing, the sole and exclusive remedy of a Party in connection with any matter arising under this Agreement shall, in each case, be indemnification under and as set forth in this Article VII. 

 

	Section  7.6	Tax Treatment of Indemnity Payments. 

 Each Party, to the extent permitted by applicable Law,
agrees to treat any payments made pursuant to this Article VII as adjustments to the Purchase Price for all federal and state income and franchise Tax purposes. 

Article VIII 

MISCELLANEOUS PROVISIONS

releases announcing this transaction exchanged among the Parties prior to the Execution Date. Notwithstanding the foregoing, in the event any such press release or announcement is required by Law or stock exchange rule to be made by the Party

Notwithstanding the foregoing sentence in this Section 8.3, to the extent that the Partnership incurs any fees or expenses in connection with the transactions contemplated by this Agreement, CST shall be responsible, and shall reimburse
the Partnership for any such fees and expenses; provided, however, that CST shall not be obligated to reimburse Lehigh GP or the Partnership for any fees or expenses the type of which are contemplated in Section 2.9 in
excess of $1,000,000 in the aggregate, whether under this Agreement or the GP Purchase Agreement.

	Section 8.7	Severability. 

 This Agreement shall be deemed severable, and the invalidity or unenforceability

the Parties shall negotiate in good faith to modify this Agreement to include a provision as similar in terms to such invalid or unenforceable provision as may be possible and be valid and enforceable.

	Section 8.10	Post-Closing Enforcement of the Agreement; Damages. 

 Each of the Parties acknowledges and agrees
that an award of monetary damages would be inadequate for any Breach of this Agreement by any Party of any covenant or obligation to be performed after the Closing, and any such Breach would cause the non-breaching Parties irreparable harm. Each of
the Parties acknowledges and agrees that in the event any covenant or obligation of the acknowledging Party to be performed after Closing is not performed in accordance with the specific terms of this Agreement or is otherwise breached, then the
other Party shall be entitled to an injunction or injunctions to prevent such non-performance or Breach and to specifically enforce the covenants and obligations of the acknowledging Party to be performed after Closing, in any courts of the State of

	Section 8.11	Governing Law. 

 This Agreement shall be governed by and construed in accordance with the internal
and substantive Laws of the State of Delaware and without regard to any conflicts of Laws concepts that would apply the substantive Law of some other jurisdiction. 
  

	Section 8.12	Disclosure. 

 Certain information set forth in the Schedules is included solely for informational
purposes, is not an admission of liability with respect to the matters covered by the information, and may not be required to be disclosed pursuant to this Agreement. Disclosure of any item in any section of the Schedules shall serve to qualify the
correspondingly numbered section or subsection in this Agreement and any other section or subsection of this Agreement to the extent the applicability of such disclosure to such section of subsection is reasonably apparent on its face to the
non-disclosing party. The specification of any dollar amount in the representations and warranties contained in this Agreement or the inclusion of any specific item in the Schedules is not intended to imply that such amounts (or higher or lower
amounts) or specific item are or are not material, and no party shall use the fact of the setting of such amounts or the fact of the inclusion of any such item in the Schedules in any dispute or controversy between the Parties as to whether any
obligation, item, or matter not described in this Agreement or included in a Schedule is or is not material for purposes of this Agreement. 
  

	Section 8.13	Consent to Jurisdiction. 

 To the fullest extent permitted by applicable Law, the Parties hereby
irrevocably submit to the jurisdiction of the courts of the State of Delaware and of the federal courts of the United States of America located in Delaware over any dispute arising out of or relating to this Agreement or any of the transactions
contemplated by this Agreement, and each Party irrevocably agrees that all claims in respect of such dispute or proceeding shall be heard and determined in such courts. The Parties hereby irrevocably waive, to the fullest extent permitted by
applicable Law, any objection that they may now or hereafter have to the venue of any dispute arising out of or relating to this Agreement or any of the transactions contemplated by this Agreement brought in such court or any defense of inconvenient
forum for the maintenance of such dispute. Each Party agrees that a judgment in any dispute heard in the venue specified by this section may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by applicable
Law. 
  

	Section 8.14	Waiver of Trial by Jury.

experience in analyzing and investing in entities like CAPL and is capable of evaluating the merits and risks of its investment in the Consideration consisting of CAPL Common Units. CST is acquiring the CAPL Common Units solely for the purpose of

of property and liability insurance related to the assets of CSTMS and the Business in such amounts, with such deductibles, and against such risks and losses as are, in its reasonable business judgment, reasonable for the Business and the Operating
Assets. All such policies are in full force and effect, all premiums due and payable thereon have been paid, and no notice of cancellation, termination or non-renewal has been received, or, to CST’s knowledge, threatened, with respect to any
such policy that has not been replaced on substantially similar terms prior to the date of such cancellation. To CST’s knowledge, the activities and operations of the Business have been conducted in a manner so as to conform in all material
respects to all applicable provisions of those insurance policies.

this Article 2, CST makes no representations or warranties whatsoever and disclaims all liability and responsibility for any other representation, warranty, statement or information made or communicated (orally or in writing), including,

directors and employees of the General Partner but otherwise excluding any of CST and its affiliates) (the “CAPL Indemnified Parties”) harmless from and against any and all damages suffered or incurred by the CAPL Indemnified
Parties as a result of or arising out of (a) any inaccuracy, violation or breach of a representation or warranty of CST in this Agreement or (b) any breach of any other agreement or covenant on the part of CST made under this Agreement.

 6.2 Indemnification of CST. 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.

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. 

6.4 Survival. 

(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

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. 

 6.5 Demands. 

(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. 
 6.6 Right 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. 

6.7 Cooperation. 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. 
 6.8 Right 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. 
 6.9 Payment 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. 

6.10 Limitations 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). 

 ARTICLE 7

 7.5 Governing 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

 7.6 Severability. 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

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. 

7.9 Specific 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.
