Each of the Recipients is duly qualified to transact business as a limited partnership or limited liability company and is in good standing in each other jurisdiction in which such qualification is required for the conduct of its business, except where the failure to so qualify or to be in good standing does not have a material adverse effect on the business, financial condition or results of operations of the Recipients, taken as a whole (a “Recipient Material Adverse Effect”).

     4.2 Authority and Approval. Each of the Recipients has the partnership or limited liability company power and authority to execute and deliver this Agreement, to consummate the Transactions and to perform all the terms and conditions hereof to be performed by it. The execution and delivery by the Recipients of this Agreement, the performance by each of them of all the terms and conditions hereof to be performed by it and the consummation of the Transactions have been duly authorized and approved by all requisite partnership or limited liability company action of each of the Recipients. This Agreement constitutes the valid and binding obligation of each of the Recipients, enforceable in accordance with its terms, except as such enforcement may be limited by bankruptcy, insolvency, reorganization, moratorium or other similar laws affecting enforcement of creditors’ rights generally and by general principles of equity (whether applied in a proceeding at law or in equity).

     4.3 Delivery of Opinion. Madison Williams has delivered an opinion to the Conflicts Committee that the aggregate consideration to be paid by the Recipients as consideration for the Assets pursuant to this Agreement is fair to the common unitholders of MLP (other than EESLP and its subsidiaries) from a financial point of view.

     4.4 Brokerage Arrangements. No Recipient has entered, directly or indirectly, into any agreement with any person, firm or corporation that would obligate the Contributors or any of their affiliates (other than the Recipients) to pay any commission, brokerage or “finder’s fee” or other fee in connection with this Agreement or the Transactions.

     4.5 Newly Issued Common Units. The New Common Units being issued at Closing will be, when issued in consideration for the contribution by the Contributors of the Assets, validly issued, fully paid and nonassessable (except as such nonassessability may be affected by the Delaware Revised Uniform Limited Partnership Act) and free of any preemptive or similar rights (other than those set forth in MLP’s limited partnership agreement).

          (b) Notwithstanding anything in this Agreement, the Recipients agree that the Contributors’ obligations under this Agreement shall in no way require any Contributor to accept any condition or requirement of any regulatory approval that is or could reasonably be determined to be adverse to any Contributor, ABS 2007, ABS Leasing or EXH.

     6.2 Independent Investigation. The Recipients acknowledge that in making the decision to enter into this Agreement and to consummate the Transactions, they have relied solely on their own independent investigation of the Business and the Assets and upon the express written representations, warranties and covenants in this Agreement. Without diminishing the scope of the express written representations, warranties and covenants of the parties in this Agreement and without affecting or impairing its right to rely thereon, THE RECIPIENTS ACKNOWLEDGE THAT THE CONTRIBUTORS HAVE NOT MADE, AND THE CONTRIBUTORS HEREBY EXPRESSLY DISCLAIM AND NEGATE, ANY OTHER REPRESENTATION OR WARRANTY, EXPRESS OR IMPLIED, RELATING TO THE ASSETS OR THE BUSINESS (INCLUDING, WITHOUT LIMITATION, ANY IMPLIED OR EXPRESS WARRANTY OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE OR CONFORMITY TO MODELS OR SAMPLES OF MATERIALS).

     6.3 General. Subject to Section 6.1(c), each party hereto will use good-faith commercially reasonable efforts to take all action and to do all things necessary, proper or advisable in order to consummate the transactions contemplated by this Agreement.

     6.4 Revisions to Schedules A, B and C.

ARTICLE VII
INDEMNIFICATION

     7.1 Indemnification of the Contributors and Other Parties. Solely for the purpose of indemnification in this Section 7.1, the representations and warranties of the Recipients in this Agreement shall be deemed to have been made without regard to any materiality or Recipient Material Adverse Effect qualifiers. From and after the Closing Date, the Recipients shall indemnify and hold the Contributors and their affiliates (other than GP LLC, GP and the Recipients and their respective subsidiaries), equity holders, directors, officers, employees, agents, representatives and insurers (together with the Contributors, the “Contributor Parties”) harmless from and against any and all damages (including exemplary damages and penalties), losses, deficiencies, costs, expenses, obligations, fines, expenditures, claims and liabilities, including reasonable counsel fees and reasonable expenses of investigation, defending and prosecuting litigation (collectively, the “Damages”), suffered by the Contributor Parties as a result of, caused by, arising out of, or in any way relating to (a) any breach of a representation or warranty of any Recipient in this Agreement, (b) any breach of any agreement or covenant under this Agreement on the part of any Recipient or (c) the ownership, operation or conduct of the Businesses or the Assets on or after the Closing Date, other than those for which the Recipients may be indemnified by the Contributors hereunder.

     7.2 Indemnification of the Recipients and other Parties. Solely for the purpose of indemnification in this Section 7.2, the representations and warranties of the Contributors in this Agreement shall be deemed to have been made without regard to any materiality or Material Adverse Effect qualifiers. The Contributors shall indemnify and hold GP LLC, GP and the Recipients and their respective subsidiaries, equity holders (other than LP LLC, MLP LP LLC and any of the Contributor Parties), directors, officers, employees, agents, representatives and insurers (together with the Recipients, the “Recipient Parties”) harmless from and against any and all Damages suffered by the Recipient Parties as a result of, caused by, arising out of, or in any way relating to (a) any breach of a representation or warranty of any Contributor in this Agreement, (b) any breach of any agreement or covenant under this Agreement on the part of any Contributor or (c) the ownership, operation or conduct of the Business or the Assets prior to the Closing Date.

     7.3 Demands. Each indemnified party 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 third party actions 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, together with a statement of such information respecting any of the foregoing as it shall have. Such notice shall include a formal demand for indemnification under this Agreement. The indemnifying party shall not be obligated to indemnify the indemnified party with respect to any Indemnity Claim if the indemnified party knowingly failed to notify the indemnifying party thereof in accordance with the provisions of this Agreement to the extent that knowing failure to notify actually results in material prejudice or damage to the indemnifying party.

     7.4 Right to Contest and Defend. The indemnifying party shall be entitled at its cost and expense to contest and defend by all appropriate legal proceedings any Indemnity Claim with respect to which it is called upon to indemnify 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 and prosecuted diligently to a final conclusion or settled in accordance with this Section 7.4 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. 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. If the indemnifying party does not elect to contest any such Indemnity Claim or elects to contest such Indemnity Claim but fails diligently and promptly to prosecute or settle such claim, the indemnifying party shall be bound by the result obtained with respect thereto by the indemnified party. If the indemnifying party shall have assumed 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.

     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.

     7.5 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. 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.

     7.6 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.

     7.7 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 loss, liability, claim, damage or expense is 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 tax benefits and other reimbursements (including, without limitation, insurance proceeds) credited to or received by the other party related to the Damages.

     7.8 Limitations on Indemnification.

          (a) To the extent the Recipient Parties are entitled to indemnification for Damages pursuant to Section 7.2(a) or (b), the Contributors shall not be liable for those Damages unless the aggregate amount of Damages exceeds $2.14 million (the “Deductible”), and then only to the extent of any such excess; provided, that the Contributors shall not be liable for Damages that exceed, in the aggregate, $21.4 million less the Deductible.

          (b) Notwithstanding clause (a) above, to the extent the Recipient Parties are entitled to indemnification for Damages for claims pursuant to Section 7.2(c) or arising from fraud, the Contributors shall be fully liable for such Damages without respect to the Deductible or the limitations in Section 7.8(a).

          (c) To the extent the Contributor Parties are entitled to indemnification for Damages pursuant to Section 7.1(a) or (b), the Recipients shall not be liable for those Damages unless the aggregate amount of Damages exceeds, in the aggregate, the Deductible, and then only to the extent of any such excess; provided, that the Recipients shall not be liable for Damages that exceed, in the aggregate, $21.4 million less the Deductible.

          (d) Notwithstanding clause (c) above, to the extent the Contributor Parties are entitled to indemnification for Damages pursuant to Section 7.1(c), related to the proviso in the first sentence of Section 6.5 or for claims arising from fraud, the Recipients shall be fully liable for such Damages without respect to the Deductible and the limitations in Section 7.8(c).

     7.9 Survival.

          (a) The liability of the Contributors for the breach of any of the representations and warranties of the Contributors set forth in Sections 3.1, 3.2, 3.3 and 3.11(a) shall be limited to claims for which the Recipients deliver written notice to the Contributors on or before the date that is two years after the Closing Date. The liability of the Contributors for

the breach of any of the representations and warranties of the Contributors set forth in Article III other than those set forth in the immediately previous sentence shall be limited to claims for which the Recipients deliver written notice to the Contributors on or before the date that is one year after the Closing Date.

          (b) The liability of the Recipients for the breach of any of the representations and warranties of the Recipients set forth in Article IV shall be limited to claims for which the Contributors deliver written notice to the Recipients on or before the date that is one year after the Closing Date.

     7.10 Sole Remedy. After the Closing, no party shall have liability under this Agreement or the Transactions except as is provided in this Article VII (other than claims or causes of action arising from fraud).

     7.11 Express Negligence Rule. THE INDEMNIFICATION AND ASSUMPTION PROVISIONS PROVIDED FOR IN THIS AGREEMENT HAVE BEEN EXPRESSLY NEGOTIATED IN EVERY DETAIL, ARE INTENDED TO BE GIVEN FULL AND LITERAL EFFECT, AND SHALL BE APPLICABLE WHETHER OR NOT THE LIABILITIES, OBLIGATIONS, CLAIMS, JUDGMENTS, LOSSES, COSTS, EXPENSES OR DAMAGES IN QUESTION ARISE OR AROSE SOLELY OR IN PART FROM THE GROSS, ACTIVE, PASSIVE OR CONCURRENT NEGLIGENCE, STRICT LIABILITY, OR OTHER FAULT OF ANY INDEMNIFIED PARTY. THE RECIPIENTS AND THE CONTRIBUTORS ACKNOWLEDGE THAT THIS STATEMENT COMPLIES WITH THE EXPRESS NEGLIGENCE RULE AND CONSTITUTES CONSPICUOUS NOTICE. NOTICE IN THIS CONSPICUOUS NOTICE IS NOT INTENDED TO PROVIDE OR ALTER THE RIGHTS AND OBLIGATIONS OF THE PARTIES, ALL OF WHICH ARE SPECIFIED ELSEWHERE IN THIS AGREEMENT.

ARTICLE VIII
TERMINATION

     8.1 Events of Termination. This Agreement may be terminated at any time prior to the Closing Date:

          (a) by mutual written consent of EESLP and MLP;

          (b) by either EESLP or MLP in writing after the date that is six months after the date of this Agreement if the Closing has not occurred by that date, provided that as of that date the terminating party is not in default under this Agreement;

          (c) by either EESLP or MLP in writing without prejudice to other rights and remedies the terminating party or its affiliates may have (provided the terminating party and its affiliates are not otherwise in material default or breach of this Agreement, or have not failed or refused to close without justification hereunder), if the other party or its affiliates shall have (i) materially failed to perform its covenants or agreements contained herein required to be performed on or prior to the Closing Date, or (ii) materially breached any of its representations or warranties contained herein; provided, however, that in the case of clause (i) or (ii), the defaulting party shall have a period of 30 days following written notice from the non-defaulting

party to cure any breach of this Agreement, if the breach is curable; provided further, that for purposes of this Section 8.1(c), the term “affiliates,” when used with respect to EESLP, shall not include GP LLC, GP or the Recipients and their respective subsidiaries, and, when used with respect to MLP, shall not include LP LLC, MLP LP LLC or the Contributor Parties;

          (d) by either EESLP or MLP in writing, without liability, if there shall be any order, writ, injunction or decree of any Governmental Authority binding on the parties that prohibits or restrains any party from consummating the Transactions; provided, that the applicable party shall have used its reasonable best efforts to have any such order, writ, injunction or decree removed but it shall not have been removed within 30 days after entry by the Governmental Authority; or

          (e) by EESLP, if any Governmental Authority shall have indicated that any Contributor may be required to accept any condition or requirement of any regulatory approval that is or could reasonably be determined to be adverse to that Contributor or EXH.

     8.2 Effect of Termination. In the event of the termination of this Agreement by a party as provided in Section 8.1, this Agreement shall thereafter become void except for this Section 8.2 and Section 9.3. Nothing in this Section 8.2 shall be deemed to release any party from any liability for any breach by such party of the terms and provisions of this Agreement or to impair any rights of any party under this Agreement.

If this Agreement is terminated by EESLP pursuant to Section 8.1(e), then EESLP shall reimburse MLP for 50% of its out-of-pocket expenses incurred in connection with the negotiation, execution and performance of this Agreement (including legal fees and fees paid to Madison Williams, in either case incurred by the MLP or the Conflicts Committee).

ARTICLE IX
MISCELLANEOUS

     9.1 Transfer Restrictions. For a 180-day period beginning on the Closing Date, neither the New Common Units nor any interest therein shall be transferable by MLP LP LLC without the prior written consent of MLP, except for transfers to affiliated entities of the Contributors in compliance with the provisions of the Securities Act, and the rules and regulations thereunder. MLP shall require (in form and substance reasonably satisfactory to MLP) any proposed permitted transferee of any such New Common Units or any interest therein to be acquired from MLP LP LLC to agree to take and hold such New Common Units or any interest therein subject to the provisions and upon the conditions specified in this Section 9.1. Any transfer of those New Common Units or any interest therein otherwise than in accordance with the terms of this Agreement shall be null and void.

     9.2 Registration Rights of MLP LP LLC and its Affiliates.

          (a) If (i) MLP LP LLC or any affiliate of MLP LP LLC (including for purposes of this Section 9.2, any affiliate of MLP LP LLC as of the date hereof notwithstanding

that it may later cease to be an affiliate of MLP LP LLC) desires to sell New Common Units and (ii) Rule 144 of the Securities Act (or any successor rule or regulation to Rule 144) or another exemption from registration is not available to enable such holder of New Common Units (the “Holder”) to dispose of the number of New Common Units it desires to sell at the time it desires to do so without registration under the Securities Act, then at the option and upon the request of the Holder, MLP shall file with the United States Securities and Exchange Commission (the “Commission”) as promptly as practicable after receiving such request, and use all commercially reasonable efforts to cause to become effective and remain effective for a period of not less than six months following its effective date or such shorter period as shall terminate when all New Common Units covered by such registration statement have been sold, a registration statement under the Securities Act registering the offering and sale of the number of New Common Units specified by the Holder; provided, however, that MLP shall not be required to effect more than three registrations pursuant to this Section 9.2(a) and Section 9.2(b); and provided further, however, that if the Conflicts Committee determines that the requested registration would be materially detrimental to MLP or the limited partners of MLP (other than EESLP and its subsidiaries) because such registration would (x) materially interfere with a significant acquisition, reorganization or other similar transaction involving MLP, (y) require premature disclosure of material information that MLP has a bona fide business purpose for preserving as confidential or (z) render MLP unable to comply with requirements under applicable securities laws, then MLP shall have the right to postpone such requested registration for a period of not more than three months after receipt of the Holder’s request, such right pursuant to this Section 9.2(a) or Section 9.2(b) not to be utilized more than twice in any 12-month period. In connection with any registration pursuant to the first sentence of this Section 9.2(a), MLP shall (i) promptly prepare and file (A) such documents as may be necessary to register or qualify the securities subject to such registration under the securities laws of such states as the Holder shall reasonably request; provided, however, that no such qualification shall be required in any jurisdiction where, as a result thereof, MLP would become subject to general service of process or to taxation or qualification to do business as a foreign corporation or partnership doing business in such jurisdiction solely as a result of such registration, and (B) such documents as may be necessary to apply for listing or to list the New Common Units subject to such registration on a national securities exchange as the Holder shall reasonably request, and (ii) use commercially reasonable efforts to do any and all other acts and things that may be necessary or appropriate to enable the Holder to consummate a public sale of such New Common Units in such states. Except as set forth in Section 9.2(d), all costs and expenses of any such registration and offering (other than the underwriting discounts and commissions and excluding the legal fees and other expenses incurred by the Holder) shall be paid by MLP, without reimbursement by the Holder.

          (b) If any Holder holds New Common Units that it desires to sell and Rule 144 of the Securities Act (or any successor rule or regulation to Rule 144) or another exemption from registration is not available to enable such Holder to dispose of the number of New Common Units it desires to sell at the time it desires to do so without registration under the Securities Act, then at the option and upon the request of the Holder, MLP shall file with the Commission as promptly as practicable after receiving such request, and use all reasonable efforts to cause to become effective and remain effective for a period of not less than six months following its effective date or such shorter period as shall terminate when all New Common Units covered by a shelf registration statement have been sold, a “shelf” registration statement covering the New Common Units specified by the Holder on an appropriate form under Rule 415

under the Securities Act, or any similar rule that may be adopted by the Commission; provided, however, that MLP shall not be required to effect more than three registrations pursuant to Section 9.2(a) and this Section 9.2(b); and provided further, however, that if the Conflicts Committee determines in good faith that any offering under, or the use of any prospectus forming a part of, the shelf registration statement would be materially detrimental to MLP and its Partners because such offering or use would (x) materially interfere with a significant acquisition, reorganization or other similar transaction involving MLP, (y) require premature disclosure of material information that MLP has a bona fide business purpose for preserving as confidential or (z) render MLP unable to comply with requirements under applicable securities laws, then MLP shall have the right to suspend such offering or use for a period of not more than three months after receipt of the Holder’s request, such right pursuant to Section 9.2(a) or this Section 9.2(b) not to be utilized more than twice in any 12-month period.

          (c) Except as provided in the first sentence of each of subsections (a) and (b) of this Section 9.2, MLP shall be deemed not to have used all reasonable efforts to keep the registration statement effective during the applicable period if it voluntarily takes any action that would result in Holders of New Common Units covered thereby not being able to offer and sell such New Common Units at any time during such period, unless such action is required by applicable law.

          (d) If MLP shall at any time propose to file a registration statement under the Securities Act for an offering of equity securities of MLP for cash (other than an offering relating solely to an employee benefit plan), MLP shall use all reasonable efforts to provide the Holders notice of its intention to file such registration statement and shall use all reasonable efforts to include such number or amount of securities held by the Holder in such registration statement as the Holder shall request; provided, that MLP is not required to make any effort or take any action to so include the securities of the Holder once the registration statement is declared effective by the Commission or otherwise becomes effective, including any registration statement providing for the offering from time to time of securities pursuant to Rule 415 of the Securities Act. If the proposed offering pursuant to this Section 9.2(d) shall be an underwritten offering, then, if the managing underwriter or managing underwriters of such offering advise MLP and the Holder in writing that in their opinion the inclusion of all or some of the Holder’s New Common Units would adversely and materially affect the success of the offering, MLP shall include in such offering only that number or amount, if any, of securities held by the Holder that, in the opinion of the managing underwriter or managing underwriters, will not adversely and materially affect the offering. All costs and expenses of any such registration and offering (other than the underwriting discounts and commissions and excluding the legal fees and other expenses incurred by the Holder) shall be paid by MLP, without reimbursement by the Holder.
