RELEASE OF OBLIGATIONS

2.01 Obligations to Reimburse for Executive Compensation. (a) Upon the terms and subject to the conditions of this Agreement, the General Partner and the OLP GP, for themselves and their affiliates, successors and assigns, hereby confirm that they have irrevocably released, relinquished and discharged the Partnership and the Operating Partnerships from any and all liability, obligation, claim, demand, action or suit of any kind or nature, in law or in equity, whatsoever, known or unknown, which may be asserted for or on account of or arising out of or in any manner relating to the Partnership's and/or the Operating Partnerships' obligations pursuant to Section 7.4(b) of the Master Partnership Agreement and the Operating Partnership Agreements or otherwise to reimburse the General Partner, the OLP GP or their affiliates for total compensation, including all benefits, paid for the four highest salaried officers performing duties for the General Partner with respect to the functions of operations, finance, legal, marketing and business development, treasury, or performing the function of President of the General Partner ("Executive Compensation Liabilities") for the period beginning on the date of the Original Agreement and continuing through December 31, 2008. Nothing in this Section 2.01(a) shall be deemed to have waived the obligations of the Partnership and the Operating Partnerships to reimburse the General Partner and the OLP GP for (i) employee fringe benefits and retirement benefits for their executives relating to services performed prior to the date of the Original Agreement, (ii) obligations under severance agreements with their executives to the extent currently reimbursable under the Master Partnership Agreement or (iii) any obligations in respect of their executives which are not related to compensation, including, without limitation, indemnification obligations (collectively, the "Excluded Obligations").

(b) The Partnership and the Operating Partnerships hereby reassume all Executive Compensation Liabilities arising on and after January 1, 2009; provided, however, that for the avoidance of doubt, such reassumption shall not include (i) any obligations of Holdco, MainLine Management LLC or the General Partner to any of the Executives pursuant to employment or severance agreements or arrangements (other than the Excluded Obligations) entered into between Holdco, MainLine Management LLC or the General Partner and such Executive prior to January 1, 2009, or (ii) any bonus payments to the Executives for 2008, in each case regardless of when such obligations become payable. In consideration of such reassumption, beginning with the calendar year starting January 1, 2009, Holdco shall make an annual payment calculated in accordance with Schedule A hereto, which amount may be paid on such terms and in such

installments during or after any calendar year as may be mutually agreed by Holdco and the Partnership (the "Annual Fixed Payment"). The Partnership and the Operating Partnerships acknowledge that so long as Holdco has no operations separate from its ownership of the General Partner, the Executive Compensation Liabilities assumed by the Partnership and the Operating Partnerships shall include all compensation and benefits payable to such officers, and the Annual Fixed Payment shall be deemed to include reimbursement by Holdco to the Partnership and the Operating Partnerships in respect of total compensation payable to the same persons for any services performed by such persons as officers of Holdco.

(c) Holdco, the General Partner and the OLP GP agree, unless the General Partner is removed as general partner of the Partnership, to perform the executive level functions referred to in Section 2.01(a) for the benefit of the Partnership and the Operating Partnerships in a manner satisfactory to the board of directors of the General Partner.

2.02 ESOP Obligations Generally. As of December 15, 2004, Holdco acknowledges that it has received all reimbursements due to it from the Partnership and the Operating Partnerships pursuant to the terms of the Prior Agreement in respect of (i) cash contributions made or to be made by the Company to the ESOP pursuant to the terms of the ESOP trust agreement, as necessary for the ESOP to make all payments of principal, interest and premium due under the Note Agreement, dated as of May 4, 2004, among the ESOP, The Prudential Insurance Company of America, Pruco Life Insurance Company and Pruco Life Insurance Company of New Jersey (the "Note Agreement"), (ii) cash deposits made or to be made by the Company pursuant to an obligation to maintain a minimum value of collateral pledged to secure the obligations of the ESOP or the Company in respect of the Note Agreement, (iii) income taxes incurred by the Company on the sale of LP Units made to satisfy the redemption obligations described in Section 2.03 below, and (iv) routine administrative charges and expenses common to employee stock ownership plans incurred in connection with the operation of the ESOP. Each of Holdco, the General Partner and the OLP GP hereby release, relinquish and discharge the Partnership and the Operating Partnerships from any and all further liability, obligation, claim, demand, action or suit of any kind or nature, in law or in equity, whatsoever, known or unknown, which may be asserted for or on account of or arising out of or in any manner relating to the foregoing obligations under the Prior Agreement.

2.03 No ESOP Contributions for Departing Employees. Holdco, the General Partner and the OLP GP acknowledge that neither the Partnership nor the Operating Partnerships shall be obligated to reimburse Holdco, the General Partner or the OLP GP for obligations to redeem the ESOP accounts of departing employees upon the termination of their employment with the Company, or for any other costs or expenses of or relating to the operation of the ESOP other than those specified in Section 2.02 above.

2.04 Representations and Warranties. Holdco, the General Partner and the OLP GP hereby represent and warrant to the Partnership and the Operating Partnerships, as of the date of the Original Agreement, that (a) neither the Company nor any entity treated as a single employer with the Company under Sections 414(b), 414(c), 414(m), or 414(o) of the Internal Revenue Code of 1986, as amended (the "Code"), or Section 4001(b) of the Employee Retirement Income Security Act of 1974, as amended ("ERISA"), has incurred any liability under any provision of ERISA or other applicable law relating to the ESOP; (b) the ESOP has been administered, in all material respects, in compliance with its terms and complies, both in form and operation, with the applicable provisions of ERISA (including, without limitation, the funding and prohibited transactions provisions thereof), the Code and other applicable laws; and (c) the ESOP has been determined by the Internal Revenue Service to be qualified within the meaning of Section 401 of the Code, and none of Holdco, the General Partner or the OLP GP is aware of any fact or circumstances which would adversely affect the qualified status of the ESOP.

ARTICLE III

AGREEMENT TO ACT AS GENERAL PARTNER

3.01 Failure to Act as General Partner Over the ESOP Period. Except to the extent this obligation is assumed by a successor general partner(s) pursuant to Section 3.02, the General Partner and the OLP GP shall continue to serve as the general partner of the Partnership and the Operating Partnerships, respectively, until all principal, interest and premium is paid in full under the Note Agreement and under any agreements or instruments replacing the Note Agreements have been repaid, unless the Partnership shall be sooner dissolved under Section 14.1(d) of the Master Partnership Agreement. Each Party hereto hereby (i) consents to the transactions set forth in the Assignment Agreement, including the assignment of all general partner interests in the Operating Partnerships by the General Partner to the OLP GP, and (ii) agrees that the consummation of such transactions did not violate any provision of the Prior Agreement.

3.02 Assumption of Obligations by a Successor General Partner. If the General Partner or the OLP GP is removed as general partner of the Partnership or one or more of the Operating Partnerships, respectively, during the ESOP Period (but not if the General Partner or the OLP GP voluntarily withdraws as general partner) pursuant to Section 13.1(b) of the Master Partnership Agreement, or if the General Partner or the OLP GP transfers its general partner interests in the Partnership or the Operating Partnerships pursuant to Section 11.1 of the Master Partnership Agreement, the General Partner or the OLP GP may cause the successor general partner of the Partnership and the Operating Partnerships, respectively, to assume its respective obligations, liabilities and duties under this Agreement.
