- 9 -

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

- 10 -

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.

- 11 -

6.10 Limitations on Indemnification.

(a) In no event shall EEP’s aggregate liability to the MEP Indemnified Parties under Section 6.1 exceed $52.5 million (the “Ceiling Amount”). Notwithstanding the foregoing, the Ceiling Amount shall not apply to inaccuracies, violations or breaches of any of the EEP Fundamental Representations, provided EEP’s aggregate liability for a breach of representations hereunder (including the EEP Fundamental Representations) shall not exceed an amount equal to the total amount of the Consideration.

(b) In no event shall MEP’s aggregate liability to the EEP 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 representations and warranties contained in Sections 3.1, 3.2 and 3.4 (the “MEP Fundamental Representations”), provided MEP’s aggregate liability for a breach of the MEP Fundamental Representations shall not exceed an amount equal to the dollar value of the Consideration as of the closing date.
