ARTICLE I

THE MERGER

1.01 Surviving Entity. In accordance with the provisions of this Agreement and the Act, at the Effective Time (as defined below), Merger Sub shall be merged with and into the Partnership (the “Merger”), and the separate legal existence of Merger Sub shall cease. The Partnership shall be the surviving entity in the Merger and shall continue its legal existence under the laws of the State of Maryland under the name it possesses immediately prior to the Effective Time (i.e., Presidential Associates I Limited Partnership).

1.02 Effect of the Merger.

(a) Upon the Effective Time, for all purposes of law, all of the rights, privileges and powers of Merger Sub and the Partnership shall have merged, and all their property, real, personal and mixed, and all the debts due on whatever account to any of them, as well as all other things and other causes of action belonging to any of them, shall be transferred to, vested in and devolve on the Partnership as the surviving entity of the Merger, without further act or deed, and all claims, demands, property and other interest shall be the property of the Partnership, and the title to all real estate vested in either of Merger Sub or the Partnership shall not revert or be in any way impaired by reason of the Merger, but shall be vested in the Partnership.

(b) Upon the Effective Time, all rights of creditors and all liens upon any property of either of Merger Sub or the Partnership shall be preserved unimpaired, and all debts, liabilities and duties of each of Merger Sub and the Partnership that have merged shall thenceforth attach to the Partnership, and may be enforced against it as the surviving entity to the same extent as if said debts, liabilities and duties had been incurred or contracted by it.

1.03 Additional Actions. If, at any time after the Effective Time, the Partnership shall consider or be advised that any deeds, bills of sale, assignments, assurances or any other actions or things are necessary or desirable to vest, perfect or confirm of record or otherwise in the Partnership its right, title or interest in, to or under any of the rights, properties or assets of Merger Sub acquired or to be acquired by the Partnership as a result of, or in connection with, the Merger or to otherwise carry out this Agreement, the general partners of the Partnership shall and will be authorized to execute and deliver, in the name and on behalf of Merger Sub and the Partnership or otherwise, all such deeds, bills of sale, assignments and assurances and to take and do, in the name and on behalf of Merger Sub and the Partnership or otherwise, all such other actions and things as may be necessary or desirable to vest, perfect or confirm any and all right, title and interest in, to and under such rights, properties or assets in the Partnership or to otherwise carry out this Agreement.

1.04 Effective Time; Conditions. In the event of, and as soon as is practicable after, the satisfaction or waiver of the conditions set forth in Article VI hereof, the parties hereto will cause the Merger to be consummated by filing, with the State Department of Assessments and Taxation of Maryland (the “SDAT”), Articles of Merger in substantially the form attached hereto as Exhibit A (the time of acceptance for record of such filing by the SDAT or such later time (not to exceed thirty (30) days thereafter) as is specified in such Articles of Merger being the “Effective Time”) under the Act. Contemporaneously with the filing referred to in this Section 1.04, a closing (the “Closing”) will be held at 10:00 a.m. (Eastern Time) at the offices of Equity Resource Investments, LLC, 1280 Massachusetts Ave., Cambridge, Massachusetts 02138 or at such other time and location as the parties may establish for the purpose of confirming all the foregoing. The date of the Closing is referred to as the “Closing Date.”

1.05 Effect on Outstanding Interests.

(a) Partnership Interests in Merger Sub. By virtue of the Merger, automatically and without any action on the part of the holder thereof, (i) the limited partnership interest(s) in Merger Sub outstanding immediately prior to the Effective Time shall be converted into a number of Limited Partnership Units equal to the total number of Limited Partnership Units outstanding at the Effective Time and (ii) general partnership interest(s) in Merger Sub outstanding immediately prior to the Effective Time shall be terminated.

(b) Partnership Interests in the Partnership.

(i) Limited Partnership Units. By virtue of the Merger, automatically and without any action on the part of the holder thereof, each Limited Partnership Unit outstanding immediately prior to the Effective Time, other than Dissenting Units (as defined in Section 1.07 below), shall be cancelled and extinguished and be automatically converted into, and become the right to receive, and each Eligible Limited Partner shall be entitled to receive, subject to the requirements set forth in Section 1.08, from Parent or Merger Sub, an amount per unit in cash equal to the Limited Partnership Unit Amount.

(ii) General Partnership Units. By virtue of the Merger, automatically and without any action on the part of the holder thereof, the managing general partnership interests in the Partnership and the other remaining general partnership interests outstanding immediately prior to the Effective Time (collectively the “General Partnership Interests”) shall remain outstanding immediately after the Effective Time as General Partnership Interests in the Partnership, as they existed immediately prior to the Effective Time, and no payment shall be made with respect thereto.

(iii) Termination of Rights. After the Effective Time, holders of Limited Partnership Units will cease to be, and will have no rights as, limited partners of the Partnership, and such holders’ rights will consist only of, (A) in the case of Limited Partnership Units other than Dissenting Units, the right to receive the consideration provided for in this Section 1.05 in respect of such units, and (B) in the case of Dissenting Units, the rights afforded to the holders thereof under the applicable provisions of the Act. Notwithstanding anything to the contrary in this Agreement, after the Effective Time, none of the Partnership, Parent or the Managing General Partner shall be liable to any holders of Limited Partnership Units for any amount properly paid to a public official pursuant to any applicable abandoned property, escheat or similar law.

(c) Dissenting Units. The holders of Dissenting Units, if any, shall be entitled to payment for such units only to the extent permitted by and in accordance with the provisions of the Act; provided, however, that if, in accordance with the applicable provisions of the Act, any holder of Dissenting Units shall forfeit such right to payment of the fair value of such units, such holder shall be bound by the terms of the Merger and such units shall thereupon be deemed to have been converted into and to have become exchangeable for, as of the Effective Time, the right to receive the Merger Consideration described in Section 1.05(b)(i) hereof (and the holder of such units may be treated as an Eligible Limited Partner hereunder).

(d) Tax Treatment. For federal income tax purposes, the parties to this Agreement agree to treat the Merger Consideration paid to holders of Limited Partnership Units as consideration paid by Merger Sub and/or Parent to purchase the Limited Partnership Units outstanding immediately prior to the Effective Time, other

(e) than Limited Partnership Units held by persons who perfect their dissenters rights under Maryland law (and thereby hold Dissenting Units) and who do not effectively withdraw or lose their dissenters rights.

1.06 Other Transactions.

(a) Immediately at and after the consummation of the Merger, for purposes of clarification, the general partners of the Partnership shall continue to be the general partners of the Partnership, and each Limited Partner after the Effective Time, including Parent, hereby consents thereto.

(b) Promptly after the Closing, the general partners of the Partnership shall amend and restate the Amended and Restated Limited Partnership Agreement and Certificate of Amendment of the Partnership that is in effect immediately prior to the Effective Time (the “Partnership Agreement”) to reflect, among other things, the transactions contemplated hereby.

1.07 Dissenting Units.

(a) Notwithstanding any provision of this Agreement to the contrary, holders of Limited Partnership Units which are entitled to dissenter’s rights in connection with the Merger under the Act (collectively, “Dissenting Units”) shall not be converted into or represent the right to receive the Merger Consideration. Such holders shall be entitled to receive in cash payment of the fair value of such Dissenting Units held by them in accordance with and as provided by the provisions of the Act, except that all Dissenting Units held by holders who shall have failed to perfect or who effectively shall have withdrawn or lost their rights to the payment of fair value for such units under the Act shall thereupon be deemed to have been converted into and to have become exchangeable for, as of the Effective Time, the right to receive the Merger Consideration described in Section 1.05(b)(i), without any interest thereon.

(b) All parties hereto shall give Parent and the Managing General Partner (i) prompt notice of any demand for payment of fair value received by such party, the withdrawals of any such demand, and any other instrument served pursuant to the Act and received and (ii) the opportunity to participate in all negotiations and proceedings with respect to demands for payment of fair value under the Act. No party to this Agreement shall, except with the prior written consent of Parent, which shall not be unreasonably withheld, make any payment with respect to any demands for payment of fair value or offer to settle or settle any such demands; provided, however, that if Parent withholds consent to a recommendation from the Managing General Partner or the Partnership for payment or settlement of any such demand, then Parent shall provide a written undertaking to indemnify and hold harmless the Partnership and the Managing General Partner from any and all amounts, including, but not limited to, attorneys’ fees, which may be awarded to the holders of such Dissenting Units in respect of such Dissenting Units, to the extent that the amount of such award is in excess of the amount which the Managing General Partner or Partnership had proposed to pay or offer to pay to the holder of such Dissenting Units.

1.08 Payment of Merger Consideration.

(a) Promptly after the Effective Time, Parent shall mail to each holder of Limited Partnership Units a notice and form of letter of transmittal and instructions to advise each Eligible Limited Partner of the effectiveness of the Merger and the procedures for obtaining the Merger Consideration, which letter of transmittal will include a release of all claims that such holder may have against the Partnership, Parent (and its Affiliates) and the Managing General Partner and the Associate General Partner (and their respective Affiliates) arising in connection with the Partnership. Upon the surrender to the Managing General Partner of such letter of transmittal, duly completed and validly executed in accordance with the instructions thereto, and such other documents as may be required pursuant to such instructions, such holder shall receive the Merger Consideration, without any interest thereon; and the Limited Partnership Units, to the extent certificated, shall be cancelled. Each of the parties hereto (as may be appropriate under the circumstances), shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement such amounts as it is required to deduct and withhold with respect to the making of such payment under the Code (including, without limitation under Code Section 1445 or Code Section 3406), or any provision of state, local or foreign tax law. To the extent that amounts are so withheld, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to such person in respect of which such deduction and withholding was made. If any Merger Consideration is to be paid to a Person other than the Person in whose name a Limited Partnership Unit is registered with the Partnership, it shall be a condition to such payment that the Person requesting such payment shall pay to the Partnership any transfer or other taxes required by reason of the payment of such Merger Consideration to a Person other than that of the registered holder of such Limited Partnership Unit, or such Person shall establish to the satisfaction of the Managing General Partner that such tax has been paid or is not applicable. Notwithstanding the foregoing, no party hereto shall be liable to a holder of units for any Merger Consideration delivered to a public official pursuant to applicable abandoned property, escheat or similar laws.

(b) Parent will promptly deliver the Merger Consideration to each Eligible Limited Partner upon receipt from such Eligible Limited Partner of the appropriately completed transmittal form. Until a transmittal form is properly delivered, an Eligible Limited Partner will not be entitled to payment of any Merger Consideration. All costs and expenses of the disbursing agent will be paid by the Partnership [prior] [true?] to the Merger.

(c) At and after the Effective Time, there shall be no transfers on the partnership books of the Partnership of the units which were outstanding immediately prior to the Effective Time (other than units held by Parent or its Affiliates).

- 4 -

(d) The provisions of this Section 1.08 shall also apply to Dissenting Units that lose their status as such.
