(c) All reasonable fees and expenses of the Indemnified Party that are Damages for which the Indemnified Party is entitled to indemnification hereunder (including reasonable fees and expenses to the extent incurred in connection with investigating or preparing to defend such Legal Proceeding in a manner not inconsistent with this Agreement) shall be paid to the Indemnified Party, as incurred, within ten (10) Business Days after written notice thereof to the Indemnifying Party; provided, however, the Indemnifying Party may require such Indemnified Party to undertake to reimburse all such fees and expenses to the extent it is judicially determined that such Indemnified Party is not entitled to indemnification for such fees and expenses hereunder.

13

(b) For purposes of determining the amount of Damages, with respect to any asserted claim for indemnification by a MLP Indemnitee, such determination shall be made without regard to any qualifier as to “material,” “materiality” or Material Adverse Effect expressly contained in Article III (except in the case of the term Material Contract); provided, however, this Section 6.4(b) shall not so modify the representations and warranties for purposes of first determining whether a breach of any representation or warranty has occurred.

(c) NOTWITHSTANDING ANYTHING TO THE CONTRARY IN THIS AGREEMENT, THE PARTIES EXPRESSLY AGREE NEITHER CONTRIBUTOR NOR MLP SHALL HAVE ANY LIABILITY TO ANY PARTY FOR ANY EXEMPLARY, PUNITIVE, INDIRECT, CONSEQUENTIAL, SPECIAL, REMOTE, OR SPECULATIVE DAMAGES, SAVE AND EXCEPT SUCH DAMAGES PAYABLE WITH RESPECT TO THIRD PARTY CLAIMS FOR WHICH SUCH INDEMNIFYING PARTY IS OBLIGATED TO PROVIDE INDEMNIFICATION UNDER SECTION 6.2.

Section 6.5 Exclusive Remedy. The indemnities in Section 6.2 shall survive Closing. The indemnities provided in Section 6.2 and the provisions of Section 7.11 shall, from and after Closing, be the sole and exclusive remedy of MLP and Contributor against one another and their respective Representatives relating to this Agreement and the transactions that are the subject of this Agreement; provided, however, no limitations set forth in this Article VI shall apply to any claim for Damages arising from fraud, willful misconduct, criminal acts, or knowing and intentional breach of this Agreement.

Section 7.6 Disclosure Schedules. The inclusion of any information (including dollar amounts) in any of the Schedules delivered by Contributor pursuant to this Agreement (collectively, the “Disclosure Schedules”) shall not be deemed to be an admission or acknowledgment by any Party that such information is required to be listed on such section of the relevant Disclosure Schedules or is material to or within or outside the ordinary course of business of such Party. The information contained in this Agreement, the Exhibits hereto, and the Disclosure Schedules is disclosed solely for purposes of this Agreement, and no information contained herein or therein shall be deemed to be an admission by any Party hereto to any third party of any matter whatsoever (including any violation of any Law or breach of contract).

In addition to any other remedy at law or in equity, each of Contributor and MLP shall be entitled to specific performance by the other Party of its obligations under this Agreement and immediate injunctive relief, without the necessity of proving the inadequacy of money damages as a remedy.

Section 7.12 Publicity.
