(ii)       
          Reimbursement of Expenses. At the Closing or the earlier termination of
          this Agreement by Seller under Section 12.03 hereof on account of a breach of
          this Agreement by Buyer or under Section 9.04 hereof on account of a
          failure of a condition under Section 9.02 (other than under Sections
          9.02(c) or (d) hereof), Buyer shall reimburse Seller (and/or the Partnership in
          the event that the Closing is not consummated) for all reasonable and documented
          costs and expenses, if any, incurred by Seller (and/or the Partnership in the
          event that the Closing is not consummated) in connection with its obtaining from
          the Partnerships lender consent to the Defeasance of the Existing Loan (as
          both such terms are defined in Section 1.05 hereof) and as also provided in
          Section 11.02 hereof. The provisions of this Section 1.02(b)(ii) shall
          survive the termination of this Agreement.

(c)       
          Escrow Amount. At the Closing, Seller and Buyer shall enter into an
          escrow agreement in the form attached hereto as Exhibit A (the
          Escrow Agreement), pursuant to which Seller shall
          deposit Ninety Thousand Two Hundred Forty-One Dollars ($90,241) (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 Section 15 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 15 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. On the date which is
          six (6) months after the Closing Date (as defined in Section 1.06 hereof), fifty
          percent (50%) of the Escrow Amount then remaining in escrow under the Escrow
          Agreement and not then subject to an outstanding Indemnification Claim shall be
          paid by the Escrow Agent to Seller. The Escrow Agreement shall expire upon the
          termination of the Survival Period (as defined in Section 15.01 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.

1.03       
          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.

1.04       
          Escrow Arrangements Relating to the Deposit.

(a)       
          Deposit. Within one (1) business day after the execution and delivery of
          this Agreement, the Initial Deposit shall be delivered by Buyer to Lawyers Title
          Insurance Company, National Accounts, Boston Office, Attention: Robert G. Soule,
          Esq. (Escrow Agent). In the event that pursuant to
          Section 6.02 hereof, the Inspection Period expires without Buyer having
          exercised its right to terminate this Agreement and this Agreement being
          otherwise then in effect, the Additional Deposit shall be delivered by Buyer to
          Escrow Agent within two (2) business days after such expiration of the
          Inspection Period (the Initial Deposit and the Additional Deposit, together with
          all interest accrued thereon, being collectively referred to herein as the
          Deposit). In the event that Buyer exercises its right under
          Section 1.06 hereof to extend the Termination Date (as defined in Section 1.06
          hereof) by paying a Second Additional Deposit (as defined in Section 1.06
          hereof) into escrow, such Second Additional Deposit shall become part of the
          Deposit to be held in escrow in accordance with the terms of this Section 1.04.
          Upon receipt from Buyer of the Deposit, Escrow Agent shall invest the Deposit in
          an interest-bearing account or money market fund as directed by Buyer. All
          interest on the Deposit shall accrue to Buyer, except as otherwise provided in
          Section 12.03 hereof. At the Closing, Escrow Agent shall release the
          Deposit to Seller, which Deposit shall be credited against the balance of the
          Purchase Price owed by Buyer to Seller. By its execution and delivery of the
          Initial Receipt on the signature pages hereof, Escrow Agent shall
          agree to hold and dispose of the Initial Deposit in accordance with the terms
          and provisions of this Agreement, and to the extent that Escrow Agent receives
          the Additional Deposit as provided in Section 1.04(a) hereof, Escrow Agent will
          similarly execute and deliver the Additional Receipt on the
          signature pages hereof.

(b)       
          Escrow Provisions. Escrow Agent hereby acknowledges receipt by Escrow
          Agent of the Initial Deposit paid by Buyer to be applied to the Purchase Price
          under the terms hereof. Escrow Agent agrees to hold, keep and deliver the
          Initial Deposit, and the Additional Deposit to the extent received by Escrow
          Agent as provided in Section 1.04(a) hereof, 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 refuse to comply with any such claims or
          demands so long as such disagreement may continue. In so refusing, 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 refusal; and Escrow Agent shall 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
          be required to 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
          undisputed 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, provided, however, in
          the case of clause (a), Escrow Agent may bring an appropriate action or
          proceeding for leave to deposit said monies into any court of competent
          jurisdiction pending such adjudication and to submit such resolution of such
          dispute to such court by action of interpleader, whereupon Escrow Agents
          obligations hereunder shall terminate.

(c)       
          Indemnification. Seller 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       

Payment of Defeasance Costs. Seller and Buyer acknowledge that the Partnership has
an outstanding mortgage loan in the unpaid principal amount of $6,558,340 as of December

Collateral (as defined in the Existing Loan Documents) and to release its lien on the
Property (such release of lien, the Defeasance). In addition, at the
Closing, Buyer shall pay (i) to the Existing Lender an amount equal to all fees, costs,
expenses and charges payable to the Existing Lender under the Existing Loan Documents in

Agreements), or such earlier date or place as Buyer and Seller shall mutually agree in

one and one-half percent (1.5%) of the Purchase Price (the Second
Additional Deposit) which shall be held by the Escrow Agent in escrow

additional period not to exceed ninety (90) days during which this Agreement shall remain
in full force and effect.

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
Seller has provided to Buyer a copy of the existing owner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 Escrow Agent, in its capacity as title insurer
(the Title Insurer), 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 Seller in writing of such fact as provided above,
Seller, in its sole discretion, shall have ten (10) business days from the date Seller
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 Seller shall cause the Partnership to
remove or cure at or before the Closing with funds of the Partnership. Seller shall be
deemed to have given notice to Buyer that Seller refuses to cure any unacceptable
exceptions, which Seller may so do in its sole discretion, unless Seller, within such ten
(10) business day period, shall notify Buyer in writing that Seller will attempt to cure
such unacceptable exceptions. If Seller 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 Sellers written notice furnished as described above or the
expiration of the aforesaid ten (10) business 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 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 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 on or prior to the Closing
Date. The parties expressly agree that Monetary Liens shall not include any liens with
respect to the Existing Loan; Buyer hereby agreeing that all such liens shall be deemed to
be Permitted Exceptions.

2.02       

Survey. Seller 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 Seller
of such exceptions. If Buyer fails to so notify Seller 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 Seller in writing of such fact
as provided above, Seller, in its sole discretion, shall have fifteen (15) days from the
date Seller receives notice of such unacceptable Survey Matters to cure such Survey
Matters to Buyers reasonable satisfaction. Seller shall be deemed to have given
notice to Buyer that Seller refuses to cure any unacceptable Survey Matters, which Seller
may so do in its sole discretion, unless Seller, within such fifteen (15) day period,
shall notify Buyer in writing that Seller will attempt to cure such unacceptable Survey
Matters. If Seller 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 Sellers written notice furnished
to Buyer as described above or the expiration of the aforesaid fifteen (15) 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.

FAILURE TO PERFORM

Section 9.01 hereof which is in the control of Seller, Buyer shall have the right to
elect, in its sole discretion, at the Closing, either to waive such condition or
conditions 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, or to terminate this Agreement and
receive the return of the Deposit. Buyer agrees that Sellers failure to satisfy any
of the conditions set forth in Sections 9.01(d), 9.01(e), 9.01(f) or 9.01(h) hereof
shall only give rise to the election by Buyer under this Section 12.01 and shall not
be deemed a default by Seller under Section 12.02 hereof.

12.02       
Sellers Default. If Seller fails to fulfill any of its obligations under this
Agreement, and Buyer does not elect to acquire the Partnership Interests as provided in
Section 12.01 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, or (ii)
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); provided, that if specific
performance is not available to Buyer for any reason, Buyer shall have the right to pursue
any and all remedies, at law or in equity, on account of such Seller default.

12.03       
Buyers Default. If Buyer fails to fulfill any of its obligations under this
Agreement, Buyer shall be in default under this Agreement. In such event, Seller may
terminate this Agreement. The parties acknowledge that in the event of Buyers
failure to fulfill its 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 earned 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.
