Such notice shall state the nature and the basis of such claim to the extent then known. The Indemnifying Party shall have the right to defend and settle, at its own expense and by its own counsel, any such matter as long as the Indemnifying Party pursues the same diligently and in good faith.

Such cooperation of the Indemnified Party shall be at the cost of the Indemnifying Party. After the Indemnifying Party has notified the Indemnified Party of its intention to undertake to defend or settle any such asserted liability, and for so long as the Indemnifying Party diligently pursues such defense, the Indemnifying Party shall not be liable for any additional legal expenses incurred by the Indemnified Party in connection with any defense or settlement of such asserted liability; provided, however, that the Indemnified Party shall be entitled (a) at its expense, to participate in the defense of such asserted liability and the negotiations of the settlement thereof and (b) if (i) the Indemnifying Party has failed to assume the defense and employ counsel or (ii) if the defendants in any such Action include both the Indemnified Party and the Indemnifying Party and counsel to the Indemnified Party shall have concluded that there may be reasonable defenses available to the Indemnified Party that are different from or in addition to those available to the Indemnifying Party or if the interests of the Indemnified Party reasonably may be deemed to conflict with the interests of the Indemnifying Party, then the Indemnified Party shall have the right to select a separate counsel and to assume such legal defense and otherwise to participate in the defense of such Action, with the expenses and fees of such separate counsel and other expenses related to such participation to be reimbursed by the Indemnifying Party as incurred.

directly or indirectly, including the filing (or participation in the filing) of a registration statement with the Commission in respect of, or establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Exchange Act with respect to, any Purchased Units, or publicly announce an intention to effect any such transaction in respect of any Purchased Units, for a period of 90 days after the Closing Date; provided, however, that any Purchaser may enter into a total return swap or similar transaction with respect to the Purchased Units purchased by such Purchaser so long as the swap counterparty agrees to be bound by the terms of this Section 7.1.

Section 7.2 Interpretation of Provisions. Article, Section and Schedule references are to this Agreement, unless otherwise specified. All references to instruments, documents, contracts, and agreements are references to such instruments, documents, contracts, and agreements as the same may be amended, supplemented, and otherwise modified from time to time, unless otherwise specified. The word “including” shall mean “including but not limited to.” Whenever a Party has an obligation under this Agreement, the expense of complying with that obligation shall be an expense of such Party unless otherwise specified. Whenever any determination, consent, or approval is to be made or given by a Party, such action shall be in such Party’s sole discretion unless otherwise specified in this Agreement. If any provision in this Agreement is held to be illegal, invalid, not binding, or unenforceable, such provision shall be fully severable and this Agreement shall be construed and enforced as if such illegal, invalid, not binding, or unenforceable provision had never comprised a part of this Agreement, and the remaining provisions shall remain in full force and effect. This Agreement has been reviewed and negotiated by sophisticated parties with access to legal counsel and shall not be construed against the drafter.

Section 7.3 Survival.

The covenants made in this Agreement shall survive the Closing of the transactions described herein and remain operative and in full force and effect regardless of acceptance of any of the Purchased Units and payment therefor.

Section 7.4 No Waiver; Modifications in Writing.

(a) Delay. No failure or delay on the part of any Party in exercising any right, power or remedy hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right, power or remedy preclude any other or further exercise thereof or the exercise of any other right, power or remedy. The remedies provided for herein are cumulative and are not exclusive of any remedies that may be available to a Party at law or in equity or otherwise.

(b) Specific Waiver. Except as otherwise provided herein, no amendment, waiver, consent, modification or termination of any provision of this Agreement shall be effective unless signed by each of the Parties hereto or thereto affected by such amendment, waiver, consent, modification or termination.

Notwithstanding anything herein to the contrary, to the extent that any Purchaser has executed or is otherwise bound by a confidentiality agreement in favor of Seller as of the date hereof, such Purchaser shall continue to be bound by such confidentiality agreement in accordance with its terms. To the extent that any Purchaser has not executed or is not otherwise bound by a confidentiality agreement in favor of Seller as of the date hereof, and has actually received Confidential Information from Seller, such Purchaser will refrain, and will cause its Representatives to refrain, from disclosing to any other Person any Confidential Information; provided, however, that with respect to any Purchaser who has not executed and is not otherwise bound by a confidentiality agreement in favor of Seller as of the date hereof, Seller acknowledges that Seller has not provided such Purchaser any Confidential Information unless requested by such Purchaser. Disclosure of Confidential Information will not be deemed to be a breach of this Section 7.6 if such disclosure is made with the consent of Seller or pursuant to a subpoena or order issued by a court of competent jurisdiction or by a judicial, administrative or legislative body or committee; provided, however, that upon receipt by any Purchaser of any subpoena or order covering Confidential Information of Seller, such Purchaser will to the extent reasonably practicable promptly notify Seller of such subpoena or order.

Section 7.13 Distributions. If the Closing occurs on a date after the record date relating to a distribution to be made to holders of Common Units after the date of this Agreement, the Common Unit Price shall be reduced by the per Common Unit amount of such distribution and the applicable Purchase Price set forth on Schedule 2.1 hereto shall be reduced accordingly.
