SECTION 1

PURCHASE AND SALE

1.01 Purchase by Buyer. Upon the terms and subject to the conditions set forth in this Agreement, Buyer agrees to purchase the Partnership Interests from Seller, and Seller agrees to sell the Partnership Interests to Buyer.

1.02 Payment of Purchase Price. The aggregate purchase price for the Partnership Interests shall be Forty-Eight Million Six Hundred Sixty-Six Thousand Seven Hundred Ninety-Six and 00/100 Dollars ($48,666,796.00) (the “Purchase Price”). The Purchase Price shall be reduced by the principal balance assumed by Buyer under that certain first mortgage loan made to the Partnership by GMAC Commercial Mortgage Bank, a Utah industrial bank (the “First Lender”) on March 22, 2006 in the original principal amount of $27,000,000 (the “First Loan”) and under that certain second mortgage loan made to the Partnership by Capmark Bank, a Utah industrial bank (the “Second Lender”) on October 30, 2007 in the original principal amount of $3,700,000 (the “Second Loan”) (the First Loan and the Second Loan are collectively referred to herein as the “Existing Loan”). The interests of the First Lender in the First Loan and the Second Lender in the Second Loan have been assigned to Xxxxxx Xxx (“Lender”). The Purchase Price, after taking into account the prorations and adjustments required herein (including, without limitation, those set forth in Section 12) and after reduction by the assumed principal balance of the Existing Loan, is referred to herein as the " Equity Portion of the Purchase Price." The Purchase Price, subject to prorations and adjustments, shall be paid as follows:

(a) Initial Deposit. Five Hundred Thousand and 00/100 Dollars ($500,000.00) (the “Initial Deposit”);

(b) Additional Deposit. Five Hundred Thousand and 00/100 Dollars ($500,000.00) (the “Additional Deposit” and, together with the Initial Deposit and any and all interest accrued thereon, are collectively referred to herein as the “Deposit”); and

(c) Payment at Closing. At the Closing (as defined in Section 1.06 hereof), Buyer shall deliver to Seller cash in an amount equal to the Equity Portion of the Purchase Price, as adjusted in accordance with the provisions of this Agreement, less (i) the amount of the Deposit held by the Escrow Agent (as defined in Section 1.04(a) hereof), and (ii) the Escrow Amount (as defined in Section 1.05 hereof) to be held by the Escrow Agent in accordance with the terms of Section 1.05 hereof.

(d) Payment of Monies. All monies payable under this Agreement, unless otherwise specified in this Agreement, shall be paid by wire transfer of immediately available funds to the Seller as directed by EHGP, Inc.

1.03 Assumption of Existing Loan. The Existing Loan is secured by mortgages on the Property (collectively, the “Existing Mortgage”). The current principal balance of the First Loan is $27,000,000; the current principal balance of the Second Loan is $3,671,830.63. Seller shall pay all interest accruing on and other fees and expenses under the Existing Loan through the date prior to Closing and Buyer shall be responsible for interest on the Existing Loan from and after the Closing Date. At Closing, subject to obtaining all necessary approvals from the Lender under the Existing Loan, Buyer, as owner of all of the interests in the Partnership shall assume all obligations and agreements of Seller as owner of all of the interests in the Partnership related to the Existing Loan arising or accruing from and after the Closing Date. All loan documentation related to the Existing Loan is listed on Exhibit E and is hereinafter referred to as the "Existing Loan Documents". Copies of said Existing Loan Documents have been provided to Buyer. Buyer shall receive a credit against the Purchase Price equal to the outstanding principal balance and all accrued but unpaid interest and other fees and expenses under the Existing Loan.

(a) Buyer shall submit an application for the assumption of the Existing Loan on or prior to August 11, 2008. Each of General Partner and Buyer shall pursue the assumption of the Loan with due diligence and in good faith and shall make all commercially reasonable efforts to obtain Lender's written consent to (i) the transfer of all of the interests in the Partnership from Seller to Buyer, (ii) the assignment and assumption of the Existing Loan in accordance with the terms of this Agreement, (iii) the substitution of a non-recourse carve-out guarantor reasonably satisfactory to Buyer for Xxxx Xxxxxxxxxx as the carve-out guarantor under the Existing Loan (the “Existing Guarantor”) for all matters occurring after Closing, and (iv) the release of Xxxx Xxxxxxxxxx as the carve-out guarantor under the Existing Loan for all matters occurring after Closing hereunder (the “Lender's Consent”) (items (i)-(iv) above being referred to herein as the "assumption of the Existing Loan"). Buyer and General Partner shall provide all cooperation the other party reasonably requests in order to obtain Lender's Consent. Seller agrees to cooperate with Buyer in connection with Buyer's preparation of all applications and submissions contemplated hereunder and, without limiting the generality of the foregoing, shall furnish such information and execute and deliver such documents on behalf of the Seller as may be reasonably required in connection therewith. Buyer and Seller shall establish a mutual understanding for all communications between Partnership, its property manager, or other representative of the Seller and Lender or any tenant or tenants of the Property regarding the terms and conditions of any proposed or submitted application contemplated in connection herewith. It is understood and agreed that in no event shall Buyer obtaining supplemental financing be a condition precedent to closing the transactions contemplated herein.

(b) Subject to receipt of the Lender's Consent, at Closing, the Partnership shall continue to be bound by the terms of the Existing Loan after Closing hereunder and Buyer, as owner of all of the interests in the Partnership, shall assume the Existing Loan, pursuant to an assignment and assumption agreement (the “Loan Assignment and Assumption Agreement”) that: (i) imposes no obligation or liability on Buyer or the Substitute Carve-out Guarantor (as defined in Section 9.01(h) under the Existing Loan Documents with respect to any period prior to Closing, with the same effect as if the Existing Loan were first being disbursed to Buyer at Closing; (ii) does not modify any of the terms or provisions of the Existing Loan Documents in any respect; as reasonably determined by Buyer other than those changes reasonably requested by Buyer prior to the expiration of the Inspection Period, including, but not limited to, the inclusion of a provision for payment of a market management fee to Berkshire Property Advisors, L.L.C.; and (iii) contains an estoppel from Lender that no defaults exist on the part of Seller or the carve-out guarantor under the Existing Loan Documents; and (iv) releases the Existing Guarantor under the Existing Loan for all matters occurring after Closing (the Loan Assignment and Assumption Agreement and any other documents the Lender requires Seller and/or Buyer to execute and deliver as a condition to the assignment and assumption of the Existing Loan to Buyer are, collectively, the “Lender Assumption Documents”).

(b) Escrow Provisions. Escrow Agent agrees to hold, keep and deliver the Deposit and all other sums delivered to Escrow Agent in accordance with the terms and provisions of this Agreement. Escrow Agent shall not be entitled to any fees or compensation for its services hereunder. Escrow Agent shall be liable only to hold said sums and deliver the same to the parties named herein in accordance with the provisions of this Agreement, it being expressly understood that by acceptance of this Agreement, Escrow Agent is acting in the capacity of a depository only and shall not be liable or responsible to anyone for any damages, losses or expenses unless same shall have been caused by the gross negligence or willful malfeasance of Escrow Agent. In the event of any disagreement between Buyer and Seller resulting in any adverse claims and demands being made in connection with or for the monies involved herein or affected hereby, Escrow Agent shall not comply with any such claims or demands so long as such disagreement may continue, and, Escrow Agent shall make no delivery or other disposition of any of the monies then held by it under the terms of this Agreement, and in so doing Escrow Agent shall not become liable to anyone for such actions; and Escrow Agent shall be entitled to continue to refrain from acting until (a) the rights of the adverse claimants shall have been finally adjudicated in a court of competent jurisdiction of the monies involved herein or affected hereby, or (b) all differences shall have been adjusted by agreement between Seller and Buyer, and Escrow Agent shall have been notified in writing of such agreement signed by the parties hereto. Escrow Agent shall not disburse any of the monies held by it under this Agreement unless in accordance with either a joint written instruction of Buyer and Seller or an Escrow Demand (as hereinafter defined) from either Buyer or Seller in accordance with the provisions hereinafter set forth. Upon receipt by Escrow Agent from either Buyer or Seller (the "Notifying Party") of any notice or request (the "Escrow Demand") to perform any act or disburse any portion of the monies held by Escrow Agent under the terms of this Agreement, Escrow Agent shall give written notice to the other party (the "Notified Party"). If within five (5) business days after the giving of such notice, Escrow Agent does not receive any written objection to the Escrow Demand from the Notified Party, Escrow Agent shall comply with the Escrow Demand. If Escrow Agent does receive written objection from the Notified Party in a timely manner as aforesaid, Escrow Agent shall take no further action until the dispute between the parties has been resolved pursuant to either clause (a) or (b) above. Further, Escrow Agent shall have the right at all times to pay all sums held by it (i) to the appropriate party with the written consent of Buyer and Seller, or (ii) into any court of competent jurisdiction after a dispute between or among the parties hereto has arisen, whereupon Escrow Agent's obligations hereunder shall terminate.

(c) Indemnification. General Partner, Partnership and Buyer jointly and severally agree to indemnify and hold harmless Escrow Agent from and against any and all costs, damages and expenses, including reasonable attorneys' fees, that said Escrow Agent may incur in its compliance in good faith with the terms of this Agreement; provided, however, this indemnity shall not extend to any act of gross negligence or willful malfeasance on the part of Escrow Agent.

1.05 Escrow Amount. At the Closing, Seller and Buyer shall enter into an escrow agreement in the form attached hereto as Exhibit C (the "Escrow Agreement"), pursuant to which Seller shall deposit One Million and 00/100 Dollars ($1,000,000.00) (the "Escrow Amount") with the Escrow Agent, which shall be held by the Escrow Agent in a segregated account as security for Seller's indemnification obligations under Sections 8.10, 16 and 17 hereof. All interest accruing on the Escrow Amount shall be for the benefit of Seller. In the event Buyer makes a written claim or demand for indemnification under Section 8.10, 16 and/or Section 17 hereof (an “Indemnification Claim”), and Seller does not dispute such Indemnification Claim, or is determined to be liable for and in respect of such Indemnification Claim by a court of competent jurisdiction, then the Escrow Agent promptly thereafter shall pay such Indemnification Claim in full to Buyer, all as more particularly provided in the Escrow Agreement. The Escrow Agreement shall expire upon the termination of the Survival Period (as defined in Section 16.01 hereof), and immediately thereafter the Escrow Agent shall pay the portion, if any, of the then remaining Escrow Amount not in dispute to Seller; provided, however, that if prior to the expiration of the Survival Period, Buyer shall have made an Indemnification Claim or commenced litigation or any other proceeding on account of any such claim, the term of the Escrow Agreement shall be extended, and the Escrow Agent shall continue to hold in escrow the portion of the then Escrow Amount in dispute, in each case until the final resolution of such Indemnification Claim or litigation or proceeding relating thereto, all as more particularly provided in the Escrow Agreement.

1.06 Closing. Except as otherwise provided in this Agreement, the closing of the transactions contemplated by this Agreement (the “Closing”) shall be through an escrow administered by the Escrow Agent by means of concurrent delivery of the documents of title, transfer of interest, delivery of Title Policy (as hereinafter defined) and the Purchase Price, customarily referred to as a “New York Style” closing, at 10:00 A.M. eastern time on the date that is ten (10) days after the date of Buyer’s receipt of Lender’s Consent, as such date may be extended only to the extent necessary to complete the documentation related to the assumption of the Existing Loan and to satisfy Lender’s requirements in connection with the Existing Loan, or such other date or place as Buyer and Seller shall mutually agree in writing (the date that the Closing is actually consummated hereunder, the "Closing Date") provided, however, that if Lender's consent has not been obtained by November 5, 2008, Buyer or Seller shall have the right to terminate this Agreement by notice to the other and in such event the Deposit shall be returned to Buyer and this Agreement shall be of no further force or effect. It is agreed that time is of the essence.

SECTION 2

TITLE MATTERS

2.01 Title. Buyer's obligation to purchase the Partnership Interests shall be conditioned upon the Partnership then holding good and clear record and marketable fee simple title to the Real Property, subject only to the Permitted Exceptions (as hereinafter defined). In connection herewith, on or prior to the date of this Agreement General Partner has provided to Buyer a copy of the existing lender’s title insurance policy for the Real Property. As promptly as possible after the date of this Agreement, Buyer shall obtain at its sole expense from the Title Company, a Commitment For Title Insurance for an ALTA Owner's Form B Title Insurance Policy with such endorsements as Buyer shall reasonably require and all legible copies of all instruments and plans mentioned therein as exceptions to title (all of such items are hereinafter collectively referred to as the “Commitment”). The Commitment shall be in the amount of the Purchase Price. Should the Commitment contain any title exceptions which are not acceptable to Buyer, in its sole discretion, Buyer shall, prior to the expiration of the Inspection Period, notify Seller of such exceptions. If Buyer fails to so notify Seller of any such exceptions as described above, the exceptions set forth in Schedule B of the Commitment shall be deemed accepted by Buyer (all such exceptions being referred to herein as the “Permitted Exceptions”). If any exceptions are unacceptable to Buyer and Buyer timely notifies General Partner in writing of such fact as provided above, General Partner, in its sole discretion, shall have ten (10) business days from the date General Partner receives notice of such unacceptable exceptions to cause the Partnership to remove or cure such exceptions, to Buyer's reasonable satisfaction, except with respect to the Monetary Liens (as hereinafter defined), which General Partner shall cause the Partnership to remove or cure before the Closing with funds of the Partnership. General Partner shall be deemed to have given notice to Buyer that General Partner refuses to cure any unacceptable exceptions, which General Partner may so do in its sole discretion, unless General Partner, within such ten (10) business day period, shall notify Buyer in writing that General Partner will attempt to cure such unacceptable exceptions. If General Partner fails or refuses to cure, or to cause the Partnership to cure, said unacceptable exceptions within the time period above provided, Buyer may (a) terminate this Agreement on or before ten (10) business days after the later of the date of General Partner's written notice furnished as described above or the expiration of the aforesaid ten (10) business day notice period afforded General Partner, and the Deposit shall be returned to Buyer, or (b) if Buyer fails to so terminate, Buyer shall be deemed to have waived such exceptions and accept title subject thereto, in which event there shall be no reduction in the Purchase Price. Notwithstanding anything to the contrary contained herein, Buyer is deemed to have rejected, without any need for further notice, all mortgages (except the Existing Mortgage), deeds of trust, liens of mechanics' liens, attachments, judgments, liens to secure the payment of income taxes of Seller or Seller's constituents, delinquent property tax and assessment liens against the Real Property and any other liens against the Real Property that can be removed by the payment of a sum other than real estate taxes collected in arrears but not yet then due and payable (collectively, "Monetary Liens"), and Seller agrees, at the sole cost and expense of the Partnership, to cause all such Monetary Liens to be released or removed prior to the Closing Date.

2.02 Survey. General Partner has furnished Buyer with a copy of the most recent as-built survey of the Real Property in Seller's possession (the "Prior Survey"), and on or before the expiration of the Inspection Period, Buyer may obtain a current as-built survey (the "New Survey") of the Real Property by a registered land surveyor. Should the Prior Survey or the New Survey contain any encumbrances, encroachments or other survey defects (collectively the "Survey Matters") which are not acceptable to Buyer in its sole discretion, Buyer shall, prior to the expiration of the Inspection Period, notify General Partner of such exceptions. If Buyer fails to so notify General Partner of any unacceptable Survey Matters as described above, all Survey Matters shall be deemed accepted by Buyer. If any Survey Matters are unacceptable to Buyer and Buyer timely notifies General Partner in writing of such fact as provided above, General Partner, in its sole discretion, shall have ten (10) days from the date General Partner receives notice of such unacceptable Survey Matters to cure such Survey Matters to Buyer's reasonable satisfaction. General Partner shall be deemed to have given notice to Buyer that General Partner refuses to cure any unacceptable Survey Matters, which General Partner may so do in its sole discretion, unless General Partner, within such ten (10) day period, shall notify Buyer in writing that General Partner will attempt to cure such unacceptable Survey Matters. If General Partner fails or refuses to cure said unacceptable Survey Matters within the time period above provided, Buyer may (a) terminate this Agreement on or before ten (10) business days after the later of the date of General Partner's written notice furnished to Buyer as described above or the expiration of the aforesaid ten (10) day notice period afforded Seller, and the Deposit shall be returned to Buyer, or (b) if Buyer fails to so terminate, Buyer shall be deemed to waive such Survey Matters and accept title subject thereto, in which event there shall be no reduction in the Purchase Price.

Seller shall terminate all such employees as of the Closing Date and shall indemnify and hold Buyer harmless from and against any and all claims, losses or expenses related to such employees arising prior to Closing.

4.11 Financial Status. Neither Seller nor the Partnership has (a) made a general assignment for the benefit of its creditors; (b) had an attachment, execution or other judicial seizure of any property interest which remains in effect; or (c) become generally unable to meet its financial obligations as they mature; and neither Seller (with respect to the Partnership only) nor the Partnership has admitted in writing its inability to pay its debts as they mature.

There is not pending any case, proceeding or other action seeking reorganization, arrangement, adjustment, liquidation, dissolution or recomposition of Seller or the Partnership, or the debts of Seller or the Partnership, under any law relating to bankruptcy, insolvency, reorganization or the relief of debtors, or seeking the appointment of a receiver, trustee, custodian or other similar official for Seller, the Partnership or the Real Property.

4.13 Financial Statements. Attached as Schedule 4.13 hereto are the audited balance sheet of the Partnership as of December 31, 2007 (the “2007 Balance Sheet”), and the related statements of income, partners' equity and cash flows of the Partnership for the year then ended (together with the 2007 Balance Sheet, the “Financial Statements”). The Financial Statements are true and correct in all material respects, and have been prepared on the basis of accounting used to prepare the Partnership’s income tax returns, which is a comprehensive basis of accounting other than accounting principles generally accepted in the United States of America. The 2007 Financial Statements fairly and accurately present the financial condition of the Partnership as of the date thereof, and the statements of income, partners' equity and cash flows contained therein fairly and accurately present the results of operations of the Partnership for the periods covered thereby.

4.15 Status of Interests. The partnership interests of the Partnership are as set forth in Schedule 4.15 attached hereto. 96.474774% of such partnership interests are owned (of record and beneficially) by Seller and 3.525226% of such partnership interests are owned (of record and beneficially) by the Individual Limited Partners (the “ILP Interests”). The Partnership Interests and the ILP Interests constitute 100% of the partnership interests in the Partnership. The Partnership Interests are duly authorized, validly issued, fully paid, nonassessable, and free and clear of liens and encumbrances of any nature. Neither Seller nor the Partnership has or is bound by any (a) outstanding subscriptions, options, warrants, calls, commitments or agreements of any character calling for it to issue, deliver or sell, or cause to be issued, delivered or sold, any partnership interest or any other equity security of the Partnership, or (b) securities convertible into, exchangeable for, or representing the right to subscribe for, purchase or otherwise receive, any partnership interest or any other equity security of the Partnership, or obligating it to grant, extend or enter into any such subscriptions, options, warrants, calls, commitments or agreements. General Partner has at all times treated the Partnership as a partnership for federal income tax purposes, and will not make any election to treat the Partnership as other than a partnership.

4.16 Partnership Agreement. The Partnership Agreement attached hereto as Schedule 4.16 is a true, correct and complete copy of the Partnership Agreement. As of the date hereof, there have been no amendments, modifications or revisions to the Partnership Agreement and it remains in full force and effect.

4.17 Tax Returns.

(a) All federal, state, municipal and other tax returns ("Tax Returns") required by law to be filed by the Partnership and/or the Seller for all periods up to and including the Closing Date have been or will be duly executed and filed, and all Taxes, interest and penalties shown as owed and due on such returns and reports have or will be paid in full prior to the Closing. To Seller's knowledge, all such Tax Returns were correct and complete in all respects.

(b) The Partnership is not currently the beneficiary of any extension of time within which to file any Tax Return and has not waived any statute of limitations in respect of Taxes or agreed to any extensions of time with respect to a tax assessment or deficiency. To General Partner's knowledge, no claim has ever been made by an authority in any jurisdiction where the Partnership does not file Tax Returns that it is or may be subject to taxation by that jurisdiction. There are no liens on any of the assets of the Partnership that arose in connection with any failure (or alleged failure) to pay any Tax. All Taxes which shall become due and payable by the Partnership after the date of this Agreement but before the Closing Date shall be paid by the Partnership on or before the Closing Date. All Tax Returns and tax information returns to be filed after the date hereof but before the Closing Date by the Partnership shall be true, complete and accurate. All Taxes which the Partnership is required by law to withhold or collect have been duly withheld or collected and, to the extent required, have been paid over to the proper governmental agencies.

(c) There is no current audit pending concerning any Tax liability of the Partnership, nor have the Seller or the Partnership received any written notice of an audit concerning any Tax liability of the Partnership. There is no dispute or claim concerning any Tax liability of the Partnership either (A) claimed or raised by any governmental authority in writing or (B) as to which the General Partner has knowledge based on personal contact with any agent of such governmental authority.

(d) No taxes are currently owed by the Partnership for any partial year, except as otherwise disclosed in the Financial Statements. Not more than eighty-nine percent of the partnership interests in the Partnership, in the aggregate, has been transferred within the three (3) year period prior to the date hereof.

4.18 Existing Loan Documents. The loan documents set forth on Schedule 4.18 attached hereto constitute all loan documentation executed in connection with the Existing Loan. The copies of the Existing Loan Documents delivered by General Partner to Buyer (and to be delivered under Section 1.03 and 3.01(p)) are true, correct and complete copies of all of the loan documents in connection with the Existing Loan. As of the date hereof, there have been no amendments, modifications or revisions to the Existing Loan Documents and they remain in full force and effect. There are no defaults on the part of Seller under the Existing Loan Documents.

4.19 Non-Contravention. The execution and delivery of this Agreement and any document, agreement or instrument to be executed and delivered by General Partner in connection herewith, and the consummation of the transactions contemplated hereby and thereby, will not (a) violate or conflict with any provision of the governing or constituent documents of General Partner or the Partnership, or (b) constitute a violation of, or be in conflict with, or constitute or create a default under, or result in the creation or imposition of any encumbrance upon any property of either General Partner or the Partnership pursuant to (i) any agreement or instrument to which such General Partner or the Partnership is a party or by which any of its respective properties is bound, or (ii) to General Partner's actual knowledge, any statute, judgment, decree, order, regulation or rule of any court or governmental or regulatory authority.

4.20 Disclosure. No representation or warranty by General Partner in this Agreement or in any exhibit, schedule, written statement, certificate or other document delivered or to be delivered to Buyer pursuant hereto or in connection with the consummation of the transactions contemplated hereby contains or will contain any untrue statement of a material fact or omits or will omit to state a material fact required to be stated therein or necessary to make the statements contained therein not misleading or necessary in order to provide Buyer with proper and complete information as to the business, condition, operations and prospects of the Partnership. There is no fact which General Partner has not disclosed to Buyer in writing which materially adversely affects, or so far as General Partner can now foresee, will materially adversely affect, the business or condition (financial or other) of the Partnership or the ability of General Partner to perform its obligations under this Agreement or any of the transactions contemplated hereby.

4.21 LP Purchase Agreement Representations and Warranties. All of the representations and warranties of the Individual Limited Partners under the LP Purchase Agreement are true, complete and correct in all material respects.

At Closing, each of the persons comprising Seller shall represent and warrant to Buyer by delivering to Buyer a certificate (the “Seller's Representation Certificate”) certifying that as to itself, all representations and warranties it makes in this Agreement remain true and correct as of the Closing Date and all of the representations and warranties contained herein shall be deemed remade by it effective as of the Closing Date; provided, however, that to the extent that changes in facts or circumstances after the date of this Agreement have occurred, it shall promptly deliver written notice to Buyer of such facts or circumstances after becoming aware of same (but in no event later than the Closing Date) and, the Seller's Representation Certificate may be revised at Closing to make exception or qualification with respect to such matters as may be necessary for such representations to remain true, but Buyer's agreement to allow such amendment of Seller's Representation Certificate shall not affect or indicate any waiver of any condition to Closing set forth in this Agreement, and Buyer may terminate this Agreement and receive the Deposit, if it fails, for any reason, to deliver Seller's Representation Certificate at Closing without any material change, except as to changes which are permitted or contemplated pursuant to Section 8 hereof.

If Buyer notifies Seller prior to Closing that any representation or warranty made in Section 5 is not true and correct in any material respect and Seller fails to cure or remedy the same prior to Closing, Buyer may either (a) terminate this Agreement and the Deposit shall be returned to Buyer, and neither party shall have further rights or obligations pursuant to this Agreement, except for Buyer's obligation to repair any damage to the Property and to indemnify Seller as set forth in Section 6.01; or (b) waive any such representation or warranty and close the transaction without any reduction in the Purchase Price. General Partner shall be required to spend up to Two Hundred Fifty and 00/100 Dollars ($250,000.00) in the pursuit of a cure or remedy of a breach of any representation or warranty made in Section 5.

If subsequent to Closing Buyer notifies Seller within twelve (12) months after Closing that Buyer discovered post-closing that any representation or warranty made in Section 4 was not true and correct and specifying the breach with particularity, Buyer shall have available all remedies at law or in equity as a consequence thereof (including, without limitation, the right to recover under the Escrow Agreement). If Buyer does not notify Seller of the breach of any of its representations and warranties set forth in this Section 5 and institute a lawsuit therefor in a court of competent jurisdiction within twelve (12) months after the Closing, Buyer shall be deemed to have waived all of its rights to claim and xxx for any breach by Seller of any of its representations and warranties made in this Section 4, except with respect to the representations and warranties set forth in Section 4.15 which shall survive the Closing Date and the expiration of the Survival Period (as defined below).

SECTION 6

INSPECTION CONDITION; "AS IS" PURCHASE

6.01 From the date of this Agreement through the Closing, Buyer, its agents and representatives, shall be entitled to enter upon the Real Property (as coordinated through the Management Company), including all leased areas and apartment units, upon reasonable prior notice to Seller, to perform inspections and tests of the Property, including surveys, environmental studies, examinations and tests of all structural and mechanical systems within the Improvements, and to examine (a) all leases, contracts, books, records and accounting reports of Partnership or Partnership's property manager relating to the Real Property, (b) title and survey, (c) compliance with all zoning, building and other laws and regulations, (d) an engineering and physical inspection, (e) an environmental study, and (f) an inspection of such other matters as Buyer determines.

Notwithstanding the foregoing, Buyer shall not be permitted to interfere materially and unreasonably with the Partnership's operations at the Real Property or interfere with any tenant's occupancy at the Real Property, and the scheduling of any inspections shall take into account the timing and availability of access to tenants' premises, pursuant to tenants' rights under the Leases or otherwise. Buyer shall repair any damage to the Property caused by its employees, agents and contractors conducting any such tests or investigations, and indemnify Partnership from and against any and all liabilities, claims, costs and expenses resulting therefrom, provided, however, that the foregoing indemnity shall not be applicable to conditions merely discovered by Buyer, but not originally caused by Buyer, nor shall such indemnity extend to liabilities, costs, expenses, damages or injuries caused by or arising out of the acts or omissions of Partnership or its agents. The foregoing indemnification shall survive the Closing or the termination of this Agreement. Prior to Closing hereunder, Buyer's and its agents' activities at the Property shall be covered by a general liability insurance policy maintained by Buyer in a commercially reasonable amount. Buyer shall provide Seller with a certificate evidencing such insurance and naming the Partnership as an additional insured.

6.02 The term "Inspection Period," as used herein, shall mean the period ending at 5:00 p.m. Boston time on August 7, 2008. Buyer shall have the right to terminate this Agreement, in its sole discretion, for any reason or no reason, by giving written notice of such election to Seller on any day prior to and including the final day of the Inspection Period, in which event the Initial Deposit shall be returned forthwith to Buyer and, except as expressly set forth herein, neither party shall have any further liability or obligation to the other hereunder. In the absence of such written notice, the contingency provided for in this Section 6.02 shall no longer be applicable, Buyer shall be deemed to have waived its right to terminate under this Section 6.02, and this Agreement shall continue in full force and effect.

6.03 EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, IT IS UNDERSTOOD AND AGREED THAT SELLER IS NOT MAKING AND HAS NOT AT ANY TIME MADE ANY REPRESENTATIONS OR WARRANTIES OF ANY KIND OR CHARACTER, EXPRESS OR IMPLIED, WITH RESPECT TO THE PROPERTY OR THE PARTNERSHIP INTERESTS, INCLUDING, BUT NOT LIMITED TO, ANY REPRESENTATIONS OR WARRANTIES AS TO MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. BUYER ACKNOWLEDGES AND AGREES THAT UPON THE CONSUMMATION OF THE CLOSING, SELLER SHALL SELL AND CONVEY TO BUYER, AND BUYER SHALL ACCEPT, THE PARTNERSHIP INTERESTS AND INDIRECTLY THE PROPERTY "AS IS, WHERE IS, WITH ALL FAULTS," EXCEPT TO THE EXTENT EXPRESSLY PROVIDED OTHERWISE IN THIS AGREEMENT. BUYER HAS NOT RELIED AND WILL NOT RELY ON, AND SELLER IS NOT LIABLE FOR OR BOUND BY, ANY EXPRESS OR IMPLIED WARRANTIES, GUARANTIES, STATEMENTS, REPRESENTATIONS OR INFORMATION PERTAINING TO THE PROPERTY OR THE PARTNERSHIP INTERESTS (INCLUDING SPECIFICALLY, WITHOUT LIMITATION, ANY PROSPECTUS OR PROXY STATEMENT DISTRIBUTED WITH RESPECT TO THE PROPERTY OR PARTNERSHIP INTERESTS) MADE OR FURNISHED BY SELLER TO WHOMEVER MADE OR GIVEN, DIRECTLY OR INDIRECTLY, ORALLY OR IN WRITING, UNLESS SPECIFICALLY SET FORTH IN THIS AGREEMENT. BUYER ALSO ACKNOWLEDGES THAT THE PURCHASE PRICE REFLECTS AND TAKES INTO ACCOUNT THAT THE PROPERTY IS BEING INDIRECTLY SOLD "AS-IS." THE PROVISIONS OF THIS SECTION SHALL SURVIVE CLOSING OR ANY TERMINATION OF THIS AGREEMENT.

SECTION 7

INSURANCE

7.01 Maintenance of Insurance. Until the Closing, General Partner shall cause the Partnership to cause the insurance on the Property to be maintained in amounts and coverages substantially similar to the policies in effect as of the date of this Agreement, which insurance in respect of fire and casualty shall be covered by a standard All-Risk Policy in the amount currently insured.

Buyer will cause the Partnership to obtain new insurance on the Property at the Closing.

7.02 Casualty or Condemnation. If, prior to the Closing, the Improvements or any material portion thereof (having a repair or replacement cost equal to or in excess of Five Hundred Thousand and 00/100 Dollars ($500,000) are damaged or destroyed by fire or casualty, or any part of the Property is taken by eminent domain by any governmental entity, then Buyer shall have the option, exercisable by written notice given to Seller at or prior to the Closing, to terminate this Agreement, whereupon all obligations of all parties hereto shall cease, the Deposit shall be returned to Buyer, and this Agreement shall be void and without recourse to the parties hereto except for provisions which are expressly stated to survive such termination. If Buyer does not elect to terminate this Agreement as aforesaid or if such damage or destruction or taking has a repair or replacement cost or is in an amount of less than Five Hundred Thousand and 00/100 Dollars ($500,000), Buyer shall proceed with the consummation of the Closing (to the extent then otherwise obligated to do so) without reduction or offset of the Purchase Price except as otherwise set forth in this Agreement, and in such case, unless the General Partner shall cause the Partnership to have previously restored the Real Property to its condition prior to the occurrence of any such damage or destruction, Partnership shall retain for the benefit of Buyer all amounts received or due from, and all claims against, any insurance company (including business interruption and rental loss insurance proceeds to the extent related to any period after the Closing Date) or governmental entity as a result of such destruction or taking and Buyer shall receive a credit against the Purchase Price in an amount equal to the deductible under Seller's insurance policy, provided, however, that to the extent any such insurance proceeds are insufficient to restore the Property to its condition prior to the occurrence of such damage or destruction, Buyer shall, at Seller’s election (such election to be made in writing by Seller to Buyer within three (3) business days after Buyer and Seller receive written notice of the amount of such insufficiency), either: (a) receive a credit against the Purchase Price at Closing in an amount equal to such insufficiency or (b) have the right, in its sole and absolute discretion, to terminate this Agreement and receive a refund of the Deposit by delivering written notice to Seller thereof within three (3) business days after Seller delivers written notice to Buyer of Seller’s election not to so reduce the Purchase Price at Closing.

Prior to submitting any required documentation, application or certificate in connection with such conversion, the General Partner shall deliver a copy of such materials to Buyer for Buyer’s review and approval prior to submission of the same for filing. Buyer shall reimburse Seller for all of Seller’s reasonable and actual out-of-pockets costs in connection with such conversion up to an aggregate of $10,000.00.

Buyer and Seller acknowledge and agree that the Partnership entered into a Rooftop Easement Agreement on July 31, 2006 (the “Easement”) encumbering the Property, pursuant to which the Partnership assigned to Unison Site Management, L.L.C. (“USM”) its rights under a License Agreement between the Partnership and American Tower Corporation dated May 4, 2000 (the “ATC License”). USM assigned its rights under the Easement to Cell Tower Lease Acquisition, LLC (“CTLA” and, together with USM, the “Unison Parties”) on July 31, 2006.

Seller shall indemnify, defend and hold Buyer harmless from any liability, claim, demand, loss, expense or damage that is suffered or incurred by Buyer or the Partnership arising out of or in connection with the Dispute including, without limitation, Unison’s failure to make any and all amounts payable to the Partnership after the Closing Date pursuant to the Sharing Agreement as a result of the Dispute.

Notwithstanding any terms herein to the contrary, for purposes of calculating prorations, Buyer shall be deemed to be in title to the Property, and therefore entitled to the income and responsible for the expenses, for the entire day upon which the Closing occurs.

12.02 The following apportionments shall be made between the parties at the Closing as of the close of the business day prior to the Closing:

(a) Buyer shall receive from Seller a credit for any rent and other income under Leases collected by Seller before Closing that applies to any period after Closing.

After Closing, Buyer shall apply all rent and income collected by Buyer from a tenant, first to the month in which Closing occurred, then to such tenant's current monthly rental and then to arrearages in the reverse order in which they were due, remitting promptly to Seller, any balance properly allocable to Seller's period of ownership. Buyer shall xxxx and use commercially reasonable efforts to collect such rent arrearages in the ordinary course of business, but shall not be obligated to engage a collection agency or take legal action to collect any rent arrearages. Any rent or other income received by Seller after Closing which are owed to Buyer shall be remitted to Buyer promptly after receipt for allocation and disbursement as provided herein;

(b) security deposits (together with any and all interest required to be accrued thereon pursuant to applicable law or the applicable lease); it is the intent of the parties that all refundable security deposits shown on the Rent Roll shall be retained by Partnership at Closing; and the Partnership shall continue to be directly accountable to the residents of the Property with respect to all such security deposits; provided however, the General Partner shall indemnify and hold Buyer harmless from all liabilities arising during the period prior to the Closing and relating to the security deposits transferred to Buyer;

(c) there shall be no adjustment for wages, vacation pay, pension and welfare benefits and other fringe benefits of all persons employed by Partnership at the Property; it being the intent of the parties that simultaneously with the Closing, Partnership shall terminate any existing management agreement and Buyer shall have no liability or obligation with respect to any employee of the Partnership or its management company prior to Closing provided thereafter, the Partnership or Buyer may, at Buyer's option, reemploy all or any of said employees from and after the Closing;

(d) real estate taxes, intangible property taxes, water charges and sewer charges, if any, on the basis of the most recent billing period, as reflected on the actual invoices/bills issued by the appropriate taxing authority except that if there is a water meter on the Property, apportionment at the Closing shall be based on the last available reading, subject to adjustment after the Closing on a per diem basis, when the next reading is available;

(e) Seller shall receive a credit for utility deposits for any utility accounts which are retained by Partnership;

(f) prepayments paid by Partnership, and payments received by Partnership, under assigned Service Contracts;

(g) Seller shall receive a credit in the amount of any escrowed funds held by the Lender under the Existing Loan which, after Closing, continue to be held by Lender for the benefit of Buyer and are not required to be used by Lender to cure any defaults under the Existing Loan; and

12.03 If any operating expenses or other prorations cannot conclusively be determined as of the date of Closing, then the same shall be adjusted at Closing based upon the most recently issued bills thus far and shall be re-adjusted within one hundred eighty (180) days after the Closing occurs.

12.04 Real Estate Tax Protests/Reductions. General Partner shall not withdraw, settle or otherwise compromise, nor permit the Partnership to withdraw, settle or otherwise compromise, any protest or reduction proceeding affecting real estate taxes assessed against the Real Property for any fiscal period in which the Closing is to occur or any subsequent fiscal period without the prior written consent of Buyer. Real estate tax refunds and credits received after the Closing which are attributable to the fiscal tax year during which the Closing occurs shall be apportioned between Seller and Buyer, after deducting the expenses of collection thereof, based upon the relative time periods each indirectly owns the Real Property, which obligation shall survive the Closing.

12.05 Tax Matters. The federal and Pennsylvania income tax returns of the Partnership for the short taxable year beginning January 1, 2008 and ending on the Closing Date shall be prepared and filed under the direction of Seller (the "Pre-Closing Tax Returns"). The federal and Pennsylvania income tax returns of the Partnership for the short taxable year beginning on the Closing Date and ending on December 31, 2008 shall be prepared and filed under the direction of Buyer. The City of Philadelphia Business Privilege Tax and Net Profits Tax returns for the calendar year 2008 shall be filed by Buyer with the cooperation of Seller, Seller being responsible for the portion of any tax due allocable to the period from January 1 to the date of Closing and Buyer being responsible for the portion of any tax due allocable to the period from and after the date of Closing. Any prepayments made by Seller to the City of Philadelphia with respect to such taxes shall be credited to amounts due from Seller and Buyer shall pay to Seller the amount of any excess prepayments made by Seller. Seller and Buyer agree that all determinations as to profit, loss, income and expense for their respective periods of ownership of the Partnership shall be determined by reference to actual results during the respective time period and not pro rated for any longer time period. The parties hereto shall provide to one another the right to have access to and to copy and use any records or information, and to have access to any personnel, which may be relevant in connection with the preparation of, audit of, or contest with respect to any Partnership tax returns which such party has the right to prepare and file under this Agreement, or which may affect the tax liability of such party or the Partnership. Seller and Buyer shall consult each other on an ongoing basis during the preparation of all such tax returns for the year 2008 concerning any positions to be taken therein and as to any Pre-Closing Tax Returns for which Seller has assumed responsibility for preparation and filing, and Seller shall promptly inform Buyer of any decision to extend the filing of any of the Pre-Closing Tax Returns. At least thirty (30) calendar days prior to the date on which such Pre-Closing Tax Returns are required to be filed (taking into account extensions), Seller shall deliver such Pre-Closing Tax Returns to Buyer for its review. Within ten (10) calendar days of receipt of such Pre-Closing Tax Returns by Buyer for review, Buyer shall notify (in writing) Seller of any changes to such Pre-Closing Tax Returns (including disclosures proposed to be included therein). If Seller disputes any such changes, it must notify (in writing) Buyer of any such disputed changes within five (5) calendar days or else all such changes must be included in the Pre-Closing Tax Returns when filed. The parties shall have the right to submit their dispute, within five (5) calendar days of the receipt by Buyer of the written notification that their proposed changes are disputed, for final resolution to an arbitrator jointly selected by Buyer and by Seller, which arbitration shall be completed within fifteen (15) calendar days of submission. If the parties are unable to agree on an arbitrator within the aforesaid five (5) calendar day period, Buyer, on the one hand, and Seller, on the other, shall each identify an arbitrator by the end of such period, and the arbitrators so identified shall jointly select the ultimate arbitrator. The arbitrator shall be a law or accounting firm nationally recognized in tax matters, and the costs of the arbitration shall be borne by the parties in inverse proportion as they may prevail on matters resolved by the arbitrator, which proportionate allocations shall also be determined by the arbitrator at the time the determination of the arbitrator is rendered on the merits of the matters submitted. Seller shall cause the Partnership to make an election under Section 754 of the Code with the Pre-Closing Tax Returns.

SECTION 13

FAILURE TO PERFORM

13.01 Buyer's Election. If Seller is unable to satisfy all of the Seller's obligations as set forth in this Agreement, Buyer shall have the right to elect, in its sole discretion, at the Closing, either to waive such failed obligations and to accept the Partnership Interests subject to such unfulfilled obligations and to pay therefor the Purchase Price without reduction or offset, in which case Seller shall convey such Partnership Interests for such price.

13.02 Seller's Default. If Seller fails to satisfy all of any of Seller's obligations under this Agreement, and Buyer does not elect to acquire the Partnership Interests as provided in Section 13.01 hereof, Seller shall be in default under this Agreement. In such event, Buyer may either (a) terminate this Agreement, in which case the Deposit made hereunder (together with all interest accrued thereon) shall be forthwith returned to Buyer and Buyer shall be entitled to recover Buyer's actual, out-of-pocket expenses incurred in connection with its investigation of the Property, negotiation of this Agreement, and proposed financing of the acquisition (including, without limitation, reasonable attorneys' fees), not to exceed $250,000 in the aggregate, or (b) if Buyer desires to purchase the Partnership Interests in accordance with the terms of this Agreement, Buyer shall have the right to compel specific performance by Seller hereunder (and recover Buyer's reasonable attorneys' fees and costs in connection with Buyer's specific performance action if a court of competent jurisdiction determines that Buyer is the "prevailing party" in such action), provided, however, that if specific performance is not available to Buyer because Seller has sold the Partnership Interests to a third party, Buyer shall have the right to pursue any and all remedies, at law or in equity, on account of such Seller default.

13.03 Buyer's Default. The parties acknowledge that in the event of Buyer's failure to fulfill its closing obligations hereunder it is impossible to compute exactly the damages which would accrue to Seller in such event. The parties have taken these facts into account in setting the amount of the Deposit, and hereby agree that (a) such amount (together with the interest earned thereon) is the pre-estimate of such damages which would accrue to Seller, (b) such amount represents damages and not any penalty against Buyer, and (c) if this Agreement shall be terminated by Seller by reason of Buyer's failure to fulfill Buyer's obligations hereunder, the Deposit (together with the interest thereon) shall be Seller's full and liquidated damages in lieu of all other rights and remedies which Seller may have against Buyer at law or in equity.

SECTION 17

INDEMNIFICATION

The obligations of Xxxx Xxxxxxxxxx under this Section 17.01 shall survive the Closing Date and the expiration of the Survival Period and shall not be limited to the Escrow Amount, except as otherwise provided in this Section 17.01.

A/72601405.7

17.02 Buyer's Indemnity. Buyer, the Partnership and Buyer's assignees under this Agreement shall indemnify, defend and hold Seller harmless of and from any Loss that is suffered or incurred by Seller, or any of its agents, employees, officers, directors, members, partners or contractors which both (a) arises out of a third party claim (whether or not the subject of a legal action) or an obligation in favor of a third party, and (b) arises out of a third party claim based on any act or omission, occurring on or after the Closing Date, of Buyer or the Partnership or any of their respective agents, employees, officers, directors, members, partners or contractors or otherwise arising out of the ownership or operation of the Property on or after the Closing Date. Buyer shall cause the Partnership to confirm this indemnity immediately upon completion of the Closing.

17.03 Procedure. The following provisions govern all actions for indemnity under this Article and any other provision of this Agreement. Promptly after receipt by an indemnitee of notice of any claim, such indemnitee will, if a claim in respect thereof is to be made against the indemnitor, deliver to the indemnitor written notice thereof and the indemnitor shall have the right to participate in and, if the indemnitor agrees in writing that it will be responsible for any costs, expenses, judgments, damages and losses incurred by the indemnitee with respect to such claim, to assume the defense thereof, with counsel mutually satisfactory to the parties; provided, however, that an indemnitee shall have the right to retain its own counsel, with the fees and expenses to be paid by the indemnitee, if the indemnitee reasonably believes that representation of such indemnitee by the counsel retained by the indemnitor would be inappropriate due to actual or potential differing interest between such indemnitee and any other party represented by such counsel in such proceeding. The failure of indemnitee to deliver written notice to the indemnitor within a reasonable time after indemnitee receives notice of any such claim shall relieve such indemnitor of any liability to the indemnitee under this indemnity only if and to the extent that such failure is prejudicial to the indemnitor's ability to defend such action, and the omission to so deliver written notice to the indemnitor will not relieve it of any liability that it may have to any indemnitee other than under this indemnity. If an indemnitee settles a claim without the prior written consent of the indemnitor, then the indemnitor shall be released from liability with respect to such claim unless the indemnitor has unreasonably withheld such consent.

17.04 Survival. The obligations of the parties set forth in this Section 17 shall survive the Closing Date.

18.16 Tax-Deferred Exchange. If either party (the "Advising Party") advises the other party (the "Non-Advising Party") of its intention to seek to effect a tax deferred exchange pursuant to Section 1031 of the Internal Revenue Code, in connection with the purchase of the Property, Non-Advising Party agrees to accommodate Advising Party in seeking to effect a tax deferred exchange for the Property, provided that such exchange shall not (i) delay the Closing or (ii) require Non-Advising Party to incur any cost or liability of any kind or nature on account of such exchange. Advising Party may assign its rights under this Agreement immediately prior to the Closing to an Exchange Accommodation Titleholder of Advising Party's choice for the purpose of completing such an exchange.

18.18 LP Purchase Agreement. It is the intention of the parties hereto that one hundred percent (100%) of the interests in the Partnership be conveyed to the Buyer under this Agreement and the LP Purchase Agreement and therefore Seller and Buyer would not be entering into this Agreement unless the LP Purchase Agreement is executed by the parties thereto. Therefore, it is agreed that: (a) a default under the LP Purchase Agreement shall constitute a default under this Agreement; and (b) in the event this Agreement is terminated by either party pursuant to any applicable provision contained herein, then the LP Purchase Agreement shall automatically terminate, provided however, if a condition precedent to Buyer’s obligation to purchase the limited partnership interests under the LP Purchase Agreement is not satisfied, Buyer shall nevertheless have the right, without waiving any of Buyer’s remedies under the LP Purchase Agreement, to waive such contingency and purchase 100% of the interest in the Partnership, including the Partnership Interests pursuant to the terms of this Agreement. It is the intention of the parties that the Closing hereunder and the Closing under the LP Purchase Agreement occur simultaneously. Therefore, in the event that Buyer is pursuing a remedy under the LP Purchase Agreement which causes a delay in the Closing, the Closing hereunder shall be extended until such extended Closing under the LP Purchase Agreement.
