SECTION 2. Exercise of Put Options.

(a) The Put Options shall (subject to the applicable proviso contained in Section 2(b) or (c)) be exercisable at any time during the period commencing on the date hereof and ending 15 months after the date hereof (the “Exercise Period”). A Put Option shall terminate and be of no further effect if it has not been exercised prior to the expiration of the Exercise Period.

(b) The HMSC Put Option may be exercised by HMSC at any time during the Exercise Period if HM or any of its subsidiaries has entered into an Outside Purchase Agreement that has become legally binding prior to or at the time such option is exercised in accordance with the last sentence of this Section 2(b); provided, however, that the HMSC Put Option may not be exercised if the TLCC Put Option has been validly exercised in accordance with Section 2(c) hereof prior to the time of exercise of the HMSC Put Option and the exercise thereof has not been subsequently revoked (it being understood that the TLCC Put Option may only be revoked upon the termination of the Outside Purchase Agreement, and in such event, the exercise of the TLCC Put Option will be deemed to have been automatically revoked and be null and void).

(c) The TLCC Put Option may be exercised by the TLCC Partners at any time during the Exercise Period if Eagle or any of its subsidiaries has entered into an Outside Purchase Agreement that has become legally binding prior to or at the time such option is

-2-

exercised in accordance with the last sentence of this Section 2(c); provided, however, that the TLCC Put Option may not be exercised if the HMSC Put Option has been validly exercised in accordance with Section 2(b) hereof prior to the time of exercise of the TLCC Put Option and the exercise thereof has not been subsequently revoked (it being understood that the HMSC Put Option may only be revoked upon the termination of the Outside Purchase Agreement, and in such event, the exercise of the HMSC Put Option will be deemed to have been automatically revoked and be null and void). In order to exercise the TLCC Put Option, the TLCC Partners must deliver a written notice to HMSC during the Exercise Period (i) stating that the TLCC Partners irrevocably (subject only to the proviso in the immediately preceding sentence) elect to exercise the TLCC Put Option, (ii) confirming that Eagle or any of its subsidiaries has entered into an Outside Purchase Agreement and representing that such agreement represents a legally binding obligation of the parties thereto and (iii) enclosing a copy of the Outside Purchase Agreement in the form executed by the parties thereto and any other information reasonably required by the HM Parties to confirm that the TLCC Partners have the right to exercise the TLCC Put Option.

(d) The exercise of a Put Option may not be revoked in any manner other than as provided in Section 2(b) or (c) hereof. If a Put Option is exercised during the Exercise Period and then subsequently revoked in the manner provided in Section 2(b) or (c) hereof, the revocation thereof shall not cause the Exercise Period to terminate and does not affect the ability of HMSC or the TLCC Partners to exercise their Put Option during the remainder of the Exercise Period.

(e) The parties expressly agree that in no event shall negotiation, execution or delivery of an Outside Purchase Agreement by HM or Eagle (or any subsidiary of either such party) during the Exercise Period constitute a breach of the Partnership Agreement (it being understood that any provision of the Partnership Agreement that may prohibit or restrict a party from negotiating, executing or delivering an Outside Purchase Agreement during the Exercise Period is hereby waived).

(f) During the Exercise Period, and, if a Put Option is exercised, through the closing of the Interest Purchase Agreement, the Eagle Parties expressly agree that the TLCC Partners shall, and the HM Parties expressly agree that HMSC shall, in the ordinary course, consistent with past practices: (i) continue to perform, each of their respective obligations under the Partnership Agreement, including, but not limited to, any obligation relating to a Budget (as defined in the Partnership Agreement), any other capital spending plan or any commitment to make future contributions, in each case, that has been duly approved in accordance with the Partnership Agreement; and (ii) continue to support the Partnership’s strategic projects set forth on Exhibit B.

In the case of the exercise of the HMSC Put Option, the Purchasers under the Interest Purchase Agreement shall be the TLCC Partners and the Seller shall be HMSC. In the case of the exercise of the

W I T N E S S E T H:

WHEREAS, TLCC LP, TLCC GP and HMSC are parties (in their capacity as successors to the original parties) to that certain Limited Partnership Agreement of Texas Lehigh Cement Company LP, dated October 1, 2000, as amended by (i) Amendment No. 1 to Agreement of Limited Partnership, dated as of October 2, 2000, (ii) Amendment No. 2 to Agreement of Limited Partnership, dated as of January 1, 2019 and (iii) Amendment No. 3 to Agreement of Limited Partnership, dated as of September 30, 2019 (as so amended, the “Partnership Agreement”), which is the governing partnership agreement of Texas Lehigh Cement Company LP, a Texas limited partnership (the “Partnership”);

WHEREAS, as of the date hereof, the Partnership Percentage Interests held by the partners of the Partnership as reflected in the Partnership Agreement are as follows:

Partner	Partnership Percentage Interest held as a General Partner	Partnership Percentage Interest held as a Limited Partner
TLCC GP	0.1%	0.0%
TLCC LP	0.0%	49.9%

WHEREAS, as of May 1, 2024, Eagle, TLCC GP, TLCC LP, HM and HMSC entered into the Put Option Agreement (the “Put Option Agreement”) pursuant to which (a) TLCC GP and TLCC LP (the “TLCC Partners”) granted a put option to HMSC (the “HMSC Put Option”) that entitled HMSC to require the TLCC Partners to purchase all of the Partnership Percentage Interests held by HMSC and (b) HMSC granted a put option to the TLCC Partners (the “TLCC Put Option”) that entitled the TLCC Partners to require HMSC to purchase all of the Partnership Percentage Interests held by the TLCC Partners, in each case upon the terms and conditions set forth therein;

WHEREAS, as of [●][●], 202[●], [HMSC/the TLCC Partners] exercised the [HMSC Put Option/TLCC Put Option] in accordance with the term of the Put Option Agreement and, accordingly, the Parties became obligated to enter into this Agreement in order to set forth the terms and conditions governing the purchase by [the TLCC Partners/HMSC and an Affiliate designated by it (the “Additional HM Purchaser”)] of the

Partnership Percentage Interests held by [HMSC/the TLCC Partners] (the “Subject Partnership Interests”); and

WHEREAS, capitalized terms used herein without definition have the respective meanings set forth in Article XI;

NOW, THEREFORE, in consideration of the premises, the terms and provisions set forth herein, the mutual benefits to be gained by the performance thereof and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties hereby agree as follows:

ARTICLE I
SALE AND PURCHASE

SECTION 1.1. Sale and Purchase. Upon the terms and subject to the conditions contained in this Agreement, at the Closing, the Seller[s] shall sell, assign and transfer the Subject Partnership Interests to the Purchasers, and the Purchasers shall acquire and accept the Subject Partnership Interests from the Seller[s]. In particular, the Subject Partnership Interests to be (a) sold by the Seller[s] to the Purchasers and (b) purchased by the Purchasers from the Seller[s] shall be as follows:

(a) [The Subject Partnership Interests to be sold by the Seller[s] to the Purchasers shall be as follows:

Seller	Subject Partnership Interest held as a General Partner	Subject Partnership Interest held as a Limited Partner
HMSC	0.1%	49.9%

[or]

TLCC LP	0.0%	49.9%]

(b) [The Subject Partnership Interests to be purchased by the Purchasers shall be as follows:

Purchasers	Subject Partnership Interest to be held as a General Partner	Subject Partnership Interest to be held as a Limited Partner
TLCC GP	0.1%	0.0%
TLCC LP	0.0%	49.9%

[or]

-2-

Purchasers	Subject Partnership Interest to be held as a General Partner	Subject Partnership Interest to be held as a Limited Partner
[●]	0.1%	0.0%
HMSC	0.0%	49.9%]

SECTION 1.2. Purchase Price.

(a) At least three business days prior to the Closing Date, the Seller[s] shall deliver to the Purchasers each of the following:

(i) A statement prepared in good faith by the Seller[s] (the “Initial Adjustment Statement”) in accordance with the Accounting Principles setting forth each of the following amounts:

(A) The amount of Partnership Cash the Partnership estimates will be held by the Partnership as of the Effective Time (the “Estimated Partnership Cash”);

(B) The amount of the Closing Debt to be owed by the Partnership outstanding as of the Closing Date (the “Closing Debt Amount”), including the Closing Credit Agreement Amount; and

(C) The amount of Net Working Capital that the Partnership estimates will exist as of the Effective Time (the “Estimated Working Capital”).

(ii) Written confirmations from the lenders (or their administrative agent) to whom the Closing Debt is owing, which will set forth the Closing Debt Amount.

The Purchasers and any advisors engaged by them shall be entitled to review, and the Parties shall cause the Partnership to make available for review and copying, the Partnership’s and its auditors’ working papers, trial balances and similar materials used in or relevant to the calculation of the amounts set forth in the Initial Adjustment Statement. Without limiting the generality of the foregoing, the Parties shall cause the Partnership to provide the Seller[s] and the advisors engaged by [it/them] with (i) reasonable assistance from the personnel and other representatives of the Partnership and (ii) timely and reasonable access to the books and records of the Partnership in connection with its review of the Initial Adjustment Statement.

(b) The aggregate purchase amount to be paid by the Purchasers to the Seller[s] at the Closing (the “Initial Purchase Price”) shall equal (i) fifty percent (50%) of $1,100,000,000.00, which represents the enterprise value of the Partnership agreed upon by the Parties (and which is not subject to adjustment or modification), plus (ii) the Initial Adjustment Amount (which may be a positive or a negative number). As used herein, the term “Initial Adjustment Amount” means an amount equal to fifty percent (50%) of (1) the

-3-

Estimated Partnership Cash, minus (2) the Closing Debt Amount, plus or minus (as the case may be) (3) the amount by which the Estimated Working Capital exceeds the Target Net Working Capital (such amount to be added) or by which the Target Net Working Capital exceeds the Estimated Working Capital (such amount to be subtracted). [The portion of the Initial Purchase Price to be paid by the Purchasers to each Seller shall be apportioned between the Sellers based on the percentages for Subject Partnership Interests sold by each Seller as set forth in Section 1.1(a).]

(c) Additionally, the Initial Purchase Price shall be reduced by fifty percent (50%) of the real estate and personal property Taxes and assessments relating to the Partnership’s assets which are attributable to the portion of the Straddle Period ending on the Closing Date, which amount shall equal the amount of such property Taxes for the entire Straddle Period, multiplied by a fraction the numerator of which is the number of days in the portion of the Straddle Period ending on the Closing Date, and the denominator of which is the number of days in the entire Straddle Period. To the extent the actual amount of such property Taxes for the entire Straddle Period is not finally determinable as of the Closing Date, the proration described in the preceding sentence will be made at the Closing on the basis of the best evidence then available; thereafter, when actual figures are received, re-prorations will be made on the basis of the actual figures, and a final cash settlement in respect of such property Taxes will be made between Seller[s] and Purchaser.

(d) It is the intent of the Parties that if any particular amount has been taken into consideration in determining any component of the Purchase Price or any adjustment thereto under one provision of this Agreement, such amount will no longer be deemed to give rise to a right to an adjustment under any other provision hereof to the extent doing so would result in an unintended “double” counting of such amount.

SECTION 1.3. Post-Closing Adjustment.

(a) As promptly as reasonably practicable after the Closing Date (but in no event later than 90 days thereafter), the Purchasers shall prepare and deliver to the Seller[s] a certificate (the “Final CFO Certificate”) of the Chief Financial Officer of the Parent Company that is a Purchaser Party, prepared in accordance with the Accounting Principles, which shall set forth the calculation by the Purchasers of (i) the Final Adjustment Amount and (ii) the resulting Final Payment to be made by the Purchasers to the Seller[s] or by the Seller[s] to the Purchasers (as the case may be) pursuant to Section 1.3(e) hereof. As used herein, the term “Final Adjustment Amount” means an amount equal to 50% of (1) the Final Partnership Cash, minus (2) the Closing Debt Amount, plus or minus (as the case may be) (3) the amount by which the Final Working Capital exceeds the Estimated Net Working Capital (such amount to be added) or by which the Estimated Net Working Capital exceeds the Final Working Capital (such amount to be subtracted). The Seller[s] and any advisors engaged by [it/them] shall be entitled to review, and the Purchasers shall cause the Partnership to make available for review and copying, the Partnership’s and its auditors’ working papers, trial balances and similar materials used in or relevant to the calculation of the amounts set forth in the Final CFO Certificate. Without limiting the generality of the foregoing, the Purchasers shall cause the Partnership to provide the Seller[s] and the advisors engaged by [it/them] with (i) reasonable assistance from the personnel and other representatives of the Partnership and (ii) timely and

-4-

reasonable access to the books and records of the Partnership in connection with its review of the Final CFO Certificate.

(b) The Seller[s] shall be entitled to dispute the calculation of any amount set forth in the Final CFO Certificate if [it/they] deliver[s] a written notice (an “Objection Notice”) to the Purchasers within 45 days after receipt of the Final CFO Certificate in which [it/they] object[s] to the calculation by the Purchasers of such amount and provide[s] a description of each item in dispute (each, a “Disputed Item”, and the date upon which the Seller[s] deliver[s] the Objection Notice to the Purchaser[s] being hereinafter referred to as the “Objection Date”). If no Objection Notice is delivered by the Seller[s] to the Purchasers within such 45-day period, then the determination of each amount set forth in the Final CFO Certificate shall be deemed to have been accepted by the Seller[s] and the calculation of the Partnership Cash and Final Working Capital contained therein, together with the resulting calculation of the Final Adjustment Amount, shall be final and binding on the parties hereto, absent fraud or manifest error.

(c) If the Seller[s] deliver[s] an Objection Notice to the Purchasers within the 45-day period specified in paragraph (b) above, the Purchasers and the Seller[s] shall attempt in good faith to agree upon the Disputed Items and the resulting Final Adjustment Amount during the period commencing on the Objection Date and ending 30 days thereafter (the “Negotiation Period”). If the Purchasers and the Seller[s] agree in writing prior to the expiration of the Negotiation Period upon a Final Adjustment Amount that is the same as or different from the amount calculated based upon the Final CFO Certificate, the Final Adjustment Amount shall be the amount so agreed upon by them.

(d) If the Purchasers and the Seller[s] do not agree in writing prior to the expiration of the Negotiation Period upon a Final Adjustment Amount, the Disputed Items that have not been previously resolved by written agreement (but no other matters) shall be submitted to Deloitte LLP, or, if such firm declines to serve as accounting arbiter, such other firm of independent public accountants as is mutually agreed upon by the Purchasers and the Seller[s] (in either case, the “Accounting Firm”), which Accounting Firm shall make a determination as to the unresolved Disputed Items. The Parties acknowledge and agree that all discussions related to the Objection Notice or any Disputed Items are communications made in confidence with the intent of attempting to settle a dispute, will not be disclosed to the Accounting Firm and are subject to settlement privilege. The Purchasers and the Seller[s] shall direct the Accounting Firm to render a written determination as to the unresolved Disputed Items (acting as an expert and not as an arbitrator) within 45 days following its engagement, which determination shall be in writing and shall set forth, in reasonable detail, the basis therefor and shall be based solely on (i) the definitions and other applicable provisions of this Agreement, (ii) the Accounting Principles and (iii) a single presentation (which shall be limited to the unresolved Disputed Items) submitted by each of the Purchasers and the Seller[s] to the Accounting Firm within 20 days after its engagement (which the Accounting Firm shall forward to the other party within two business days after receipt thereof). The Purchasers and the Seller[s] shall instruct the Accounting Firm not to, and the Accounting Firm will not, assign a value to any Disputed Item greater than the greatest value assigned to such item by the Purchasers or the Seller[s] or less than the lowest value assigned to such item by the Purchasers or the Seller[s]. The Accounting Firm will send its written determinations regarding the

-5-

unresolved Disputed Items (including its determination of the Partnership Cash and Final Working Capital, in each case, to the extent the determination of such amount requires the resolution of a Disputed Item) to the Purchasers and the Seller[s], together with the resulting calculation of the Final Adjustment Amount, and each such determination and calculation of the Accounting Firm shall be final and binding on the Parties, absent fraud or manifest error. The terms of engagement of the Accounting Firm shall be as reasonably agreed upon between the Purchasers and the Seller[s], and any associated engagement fees shall initially be allocated 50% to the Purchasers and 50% to the Seller[s]; provided, that, upon the determination by the Accounting Firm of the Final Adjustment Amount, such fees, costs and expenses of the Accounting Firm shall be allocated (or, if necessary, reallocated) between the Purchasers, on the one hand, and the Seller[s], on the other hand, in such proportions as reflect the ratio of (i) the amount of Disputed Items as to which each such party was unsuccessful in maintaining its position (as finally determined by the Accounting Firm) to (ii) the total amount of Disputed Items submitted to the Accounting Firm. (For example, if the Seller[s] submit[s] proposed aggregate adjustments of $1,000,000 for Disputed Items in the Objection Notice, and the Purchasers agree in writing to $500,000 of such adjustments but contests the remainder, and if the Accounting Firm ultimately resolves the dispute by finding in favor of the Seller[s] as to $300,000 of the $500,000 in unresolved Disputed Items and finding against the Seller[s] as to the remainder of such items, then the fees, costs and expenses of the Accounting Firm will be allocated 60% (i.e., 300,000/500,000) to the Purchaser[s] and 40% (i.e., 200,000/500,000) to the Seller[s].) Except as provided in this paragraph (d), all other costs and expenses incurred by the Parties in connection with resolving any dispute described in this paragraph (d) shall be borne by the Party incurring such costs and expenses.

(e) No later than five days after a binding determination of the Final Adjustment Amount has been made in accordance with Section 1.3(b), (c) or (d), as applicable, a final payment shall be made pursuant to this Section 1.3(e) (the “Final Payment”). If the Final Adjustment Amount is greater than the Initial Adjustment Amount, then an amount equal to the excess of the Final Adjustment Amount over the Initial Adjustment Amount shall be paid by the Purchasers to the Seller[s], to such account or accounts as have been designated in writing by the Seller[s]. If the Final Adjustment Amount is less than the Initial Adjustment Amount, then an amount equal to the excess of the Initial Adjustment Amount over the Final Adjustment Amount shall be paid by the Seller[s] to the Purchasers, to such account or accounts as have been designated in writing by the Purchasers. If the Final Adjustment Amount is equal to the Initial Adjustment Amount, there shall be no Final Payment to be made by either the Purchasers or the Seller[s].

(f) The process set forth in this Section 1.3 shall be the exclusive remedy of the Parties for any disputes related to the determination of Estimated Partnership Cash and Final Working Capital and the resulting Final Adjustment Amount, whether or not the underlying facts and circumstances of a Disputed Item constitute a breach of any representations or warranties of the Parties contained in this Agreement.

(g) The final purchase price payable by the Purchasers to the Seller[s] pursuant to this Agreement shall be equal to the Initial Purchase Price, as adjusted by the provisions of this Section 1.3 and any other applicable provisions of this Agreement that

-6-

expressly state that specific amounts or payments will be treated as purchase price adjustments (as so adjusted, the “Purchase Price”).

SECTION 1.4. Transfer Taxes. The Seller[s] and the Purchasers shall cooperate with each other and take any reasonable actions to minimize any documentary, stamp, sales and excise or other similar taxes payable in respect of the sale, assignment and transfer of the Subject Partnership Interests. To the extent that, notwithstanding the immediately preceding sentence, any documentary, stamp, sales and excise or other similar Taxes are required to be paid in respect of the sale, assignment and transfer of the Subject Partnership Interests, such Taxes shall be borne 50% by the Purchasers on the one hand and 50% by the Seller[s] on the one hand.

To the extent any such Income Tax Return reflects a position (including in respect of a new item) that has not been taken by the Partnership with respect to any prior year and could reasonably be expected to materially increase the Tax liability of the Partnership or Purchasers for or with respect to any Post-Closing Tax Period, such Income Tax Return shall not be filed without the consent of Purchasers (not to be unreasonably withheld, delayed or conditioned).

(e) Post-Closing Tax Proceedings. Following the Closing, the conduct of any Tax audit or administrative or court proceeding relating to any Income Tax Return of the Partnership for a taxable period ending on or prior to the Closing Date (a “Tax Proceeding”) shall be controlled by TLCC GP; provided, that TLCC GP must control such Tax Proceeding in good faith and with reasonable diligence thereafter to preserve its rights. TLCC GP shall keep HMSC fully and timely informed with respect to the commencement, status and nature of any such Tax Proceeding. TLCC GP shall consider in good faith comments made by HMSC to TLCC GP regarding the conduct of or positions taken in any such Tax Proceeding. HMSC shall, at its sole cost and expense, be entitled to fully participate in any such Tax Proceeding. Each of TLCC GP and HMSC shall have the right to consent to any settlement with respect to (or abandonment of) any such Tax Proceeding (provided such consent cannot be unreasonably withheld, conditioned or delayed). The costs and expenses of the Partnership with respect to any Tax Proceeding, including expenses of and fees for attorneys, accountants and consultants, shall be borne 50% by Purchasers and 50% by Seller[s]. Purchasers (or an Affiliate thereof) shall control in good faith any Tax audit, or administrative or court proceeding of the Partnership other than Tax Proceedings described above (the “Other Tax Proceedings”); provided that Purchasers shall control such Other Tax Proceedings in good faith and with reasonable diligence and keep Seller[s] fully and timely informed with respect to the commencement, status and nature of any such Other Tax Proceeding, Seller shall be entitled to fully participate (at its sole cost and expense) in any such Other Tax Proceeding, and Seller shall have the right to consent to any settlement with respect to (or abandonment of) any such Other Tax Proceeding (provided such consent cannot be unreasonably withheld, conditioned or delayed).

(g) Purchase Price Allocation. Seller[s] and Purchasers agree that the sum of the Purchase Price and Seller[s]’ share of the liabilities of the Partnership shall be allocated to and among the assets of the Partnership for U.S. federal income tax purposes in a manner consistent with Section 1060 of the Code and the regulations promulgated thereunder. Purchasers shall deliver to Seller[s] an allocation schedule not more than one

-25-

satisfactory to the Indemnified Party.

Except as provided in clause (i), (ii) or (iii) above, after notice from the Indemnifying Party to the Indemnified Party of its election to assume the defense of any Legal Proceeding, the Indemnifying Party shall not be liable to the Indemnified Party for any attorney’s fees or other costs or expenses subsequently incurred by the Indemnified Party in connection with the defense thereof.

(c) The Indemnifying Party shall not, without the prior written consent of each Indemnified Party (which consent shall not be unreasonably withheld or delayed), settle, compromise or consent to the entry of any judgment with respect to any pending or threatened Legal Proceeding in respect of which indemnification is being sought by such Indemnified Party hereunder (whether or not the Indemnified Party is an actual or potential party to such Legal Proceeding) unless such settlement, compromise or consent includes an unconditional release of the Indemnified Party from all liability arising out of such Legal Proceeding. An Indemnified Party shall not compromise or consent to the entry of any judgment with respect to any pending or threatened Legal Proceeding in respect of which indemnification is being sought by the Indemnified Party hereunder, without the prior written consent of the Indemnifying Party.

SECTION 10.5. Other Claims; Procedure. If an Indemnified Party desires to seek indemnification for a Claim that is not a Third-Party Claim, the Indemnified Party shall deliver a written notice to the Indemnifying Party with respect to such Claim as promptly as reasonably practicable after it determines that it will seek indemnification against Losses arising therefrom, which notice shall state the nature of the Claim and provide a brief description of the basis therefor and provide a reasonably detailed statement of the facts required in order for the Indemnifying Party to evaluate the Claim. Upon

-26-

delivery of such notice, the Parties shall, to the extent that they do not agree as to the applicability of this Article X to the relevant Losses, attempt in good faith to resolve their differences for a period of 60 days and if the Parties are unable to resolve their differences within such period, either Party may submit the matter to for resolution by appropriate Legal Proceedings in accordance with the provisions of Section 12.9.

SECTION 10.6. Reliance The rights of an Indemnified Party to indemnification for breaches of the representations and warranties of any other Parties set forth in this Agreement are part of the basis of the bargain contemplated by this Agreement, and such rights to indemnification shall not be affected or waived by virtue of, and the Indemnified Party shall be deemed to have relied upon the representations and warranties of such other Parties set forth in this Agreement notwithstanding any knowledge acquired (or capable of being acquired) by any Indemnified Party of any untruth of any such representation or warranty of such other Parties set forth in this Agreement, regardless of whether such knowledge was obtained (or was capable of being obtained) through the investigation by such Indemnified Party or through disclosure by such other Parties or any other Person, and regardless of whether such knowledge was obtained before, at or after the Closing.

SECTION 10.7. Exclusive Remedy. Unless otherwise prohibited by applicable Law (pursuant to statutory or other provisions that cannot be waived by the Parties), from and after the Closing, the remedies of the Parties specifically provided for in Article X shall be the sole and exclusive remedies available to the Parties for all matters covered or contemplated by this Agreement; provided, however, that nothing herein shall limit the right of any Party (i) to seek specific performance or injunctive relief in connection with a breach by another Party of its covenants or agreements under this Agreement that are to be performed after the Closing or (ii) to seek any remedy available at law or in equity in respect of a failure on the part of any Party to observe or comply with the terms of the Seller Party Release or Purchaser Party Release, as applicable, executed by such Party at Closing. Without limiting the generality of the foregoing, the Purchasers shall not seek any indemnification, contribution, repayment or other remedy or recourse against the Seller[s] directly or indirectly (whether by asserting a Claim against the Seller or [its/their] Affiliates or Representatives or otherwise) with respect to any matter relating to the Partnership or it business, operations, properties or assets or the subject matter of this Agreement (whether on the basis of a claim sounding in tort, contract, statute or otherwise) outside of the provisions of this Article X.
