COVERING LIQUIDATED DAMAGES, AND THAT EACH PARTY WAS REPRESENTED BY COUNSEL WHO
EXPLAINED THE CONSEQUENCES OF THIS LIQUIDATED DAMAGES PROVISION AT THE TIME THIS

         SECTION 1.7 Escrow Agent. Escrow Agent shall hold and dispose of the
Deposit and Option Deposit, if any, in accordance with the terms of this
Agreement. Seller and Purchaser agree that the duties of the Escrow Agent
hereunder are purely ministerial in nature and shall be expressly limited to the
safekeeping and disposition of the Deposit and Option Deposit, if any, in
accordance with this Agreement. Escrow Agent shall incur no liability in
connection with the safekeeping or disposition of the Deposit and Option
Deposit, if any, for any reason other than Escrow Agent's misconduct or
negligence. In the event that Escrow Agent shall be in doubt as to its duties or
obligations with regard to the Deposit and Option Deposit, if any, or in the
event that Escrow Agent receives conflicting instructions from Purchaser and
Seller with respect to the Deposit or Option Deposit, if any, Escrow Agent shall
not be required to disburse the Deposit and Option deposit, if any, and may, at
its option, continue to hold the Deposit and Option Deposit, if any, until both
Purchaser and Seller agree as to its disposition, or until a final judgment is
entered by a court of competent jurisdiction directing its disposition, or
Escrow Agent may interplead the Deposit and Option Deposit, if any, in
accordance with the laws of the state in which the Property is located.

         Escrow Agent shall not be responsible for any interest on the Deposit
or Option Deposit, if any, except as is actually earned, or for the loss of any
interest resulting from the withdrawal of the Deposit prior to the date interest
is posted thereon.

         Escrow Agent shall execute this Agreement solely for the purpose of
being bound by the provisions of Sections 1.4, 1.5, 1.6,1.7 and 4.1 hereof.

                                   ARTICLE II

                                      TITLE

         SECTION 2.1 Title Inspection Period. During the period beginning upon
the Effective Date and ending at 5:00 p.m. (local time at the Property) on June
30, 2004 (hereinafter referred to as the "Title Inspection Period"), Purchaser
shall have the right to review: (a) a current preliminary title report on the
Real Property (the "PTR") issued by Chicago Title Company (the



"Title Company"), accompanied by copies of all documents referred to in the
report; (b) copies of the most recent property tax bills for the Property; and
(c) an ALTA survey of the Real Property prepared by a licensed surveyor (the
"Survey"). Item (a) shall be obtained by Purchaser within five (5) days after
the Effective Date. Item (c) shall be obtained by Purchaser prior to the end of
the Title Inspection Period. Item (b) shall be delivered by Seller to Purchaser
within five (5) days after the Effective Date.

         SECTION 2.2 Title Examination. Purchaser shall notify Seller in writing
(the "Title Notice") prior to the expiration of the Title Inspection Period
which exceptions to title (including survey matters), if any, will not be
accepted by Purchaser. If Purchaser fails to notify Seller in writing of its
disapproval of any exceptions to title by the expiration of the Title Inspection
Period, Purchaser shall be deemed to have approved the condition of title to the
Real Property. If Purchaser notifies Seller in writing that Purchaser objects to
any exceptions to title, Seller shall have two (2) business days after receipt
of the Title Notice to notify Purchaser of either of the following: (a) that
Seller will remove such objectionable exceptions from title on or before the
Closing; or (b) that Seller elects not to cause such exceptions to be removed.
If Seller fails to notify Purchaser within such two-business-day period, then
Seller shall be deemed to have made an election under the foregoing clause (b).
Notwithstanding the foregoing or any other provision of this Agreement, all
monetary obligations disclosed in the PTR are to be satisfied by Seller. The
procurement by Seller of a commitment for the issuance of the Title Policy (as
defined in Section 2.5 hereof) or an endorsement thereto insuring Purchaser
against any title exception which was disapproved pursuant to this Section 2.2
shall be deemed a cure by Seller of such disapproval. If Seller gives Purchaser
notice under clause (b) above, Purchaser shall have three (3) business days
after the date of such notice in which to notify Seller that Purchaser will
nevertheless proceed with the purchase in accordance with the provisions of this
Agreement and take title to the Property subject to such exceptions, or that
Purchaser will terminate this Agreement. Purchaser's failure to respond within
such three-business-day period shall be deemed an election to terminate this
Agreement. If, despite Seller's election to eliminate any disapproved exception
under clause (a) above, the exception has not been eliminated on or before the
Closing, Purchaser, at its option and sole discretion, may either: (a) elect in
writing to waive its prior disapproval; (b) if the exception represents a
monetary obligation, instruct Escrow Holder to deduct from Seller's proceeds
hereunder the amount necessary to satisfy the obligation and thereby eliminate
the exception; or (c) treat the failure to eliminate the exception as a failure
of a contingency under this Agreement, in which event the Escrow shall be
cancelled and this Agreement shall be terminated. If this Agreement is
terminated pursuant to the foregoing provisions of this paragraph, then neither
party shall have any further rights or obligations hereunder (except for any
indemnity obligations of either party pursuant to the other provisions of this
Agreement), the Deposit, and Option Deposit, if any, shall be returned to
Purchaser and each party shall bear its own costs incurred hereunder.

         SECTION 2.3 Pre-Closing "Gap" Title Defects. Purchaser may, at or prior
to Closing, notify Seller in writing (the "Gap Notice") of any objections to
title: (a) raised by the Title Company between the expiration of the Title
Inspection Period and the Closing; and (b) not disclosed by the Title Company or
otherwise known to Purchaser prior to the expiration of the Title Inspection
Period; provided that Purchaser must notify Seller of such objection to title
within two (2) business days of being made aware of the existence of such
exception. If Purchaser sends a Gap Notice to Seller, Purchaser and Seller shall
have the same rights and



obligations with respect to such notice as apply to a Title Notice under Section
2.2 hereof; provided, however, in no event shall the date of Closing be extended
beyond July 30, 2004, or, if extended pursuant to Section 4.1, October 16, 2004.

         SECTION 2.4 Permitted Exceptions. The Property shall be conveyed
subject to the following matters, which are hereinafter referred to as the
"Permitted Exceptions":

                  (a) those matters (including, without limitation, the
exceptions disclosed in the PTR) that either are not objected to in writing
within the time periods provided in Sections 2.2 or 2.3 hereof, or if objected
to in writing by Purchaser, are those which Seller has elected not to remove or
cure, or has been unable to remove or cure, and subject to which Purchaser has
elected or is deemed to have elected to accept the conveyance of the Property;

                  (b) the lien of all ad valorem real estate taxes and
assessments not yet due and payable as of the date of Closing, subject to
adjustment as herein provided;

                  (c) local, state and federal laws, ordinances or governmental
regulations, including but not limited to, building and zoning laws, ordinances
and regulations, now or hereafter in effect relating to the Property;

                  (d) items shown on the Survey and not objected to by Purchaser
or waived or deemed waived by Purchaser in accordance with Section 2.2 or
Section 2.3 hereof;

                  (e) rights of tenants under leases affecting the Property,
including the lease dated as of the Closing between Seller and Purchaser in the
form attached hereto as Exhibit I (the "Lease"); and

                  (f) the lien of the deed of trust securing a loan (the "Loan")
to Purchaser from its mortgage lender ("Lender").

         SECTION 2.5 Conveyance of Title. At Closing, Seller shall convey and
transfer to Purchaser fee simple title to the Land and Improvements, by
execution and delivery of the Deed (as defined in Section 4.3(a) hereof) and
Escrow Agent shall obtain the irrevocable commitment of the Title Company to
issue an ALTA Joint Protection Policy of Title Insurance (the "Title Policy")
covering the Real Property, in the full amount of the Purchase Price, subject
only to the Permitted Exceptions

upon the Effective Date and ending at 5:00 p.m. (local time at the Property) on

independent contractors, shall have the right to make a physical inspection of
the Real Property and perform an environmental, soil, geological or other
assessment on the Property pursuant to the terms and conditions of this
Agreement.



         Purchaser understands and agrees that any on-site inspections or
environmental assessments of the Property shall occur at reasonable times agreed
upon by Seller and Purchaser after reasonable prior written notice to Seller and
shall be conducted so as not to interfere unreasonably with the use of the
Property by Seller. Seller reserves the right to have a representative present
during any such inspections. Purchaser shall promptly restore the Real Property
to its prior condition following any such inspections or assessments, at
Purchaser's sole cost and expense. At Seller's option, Purchaser will furnish to
Seller copies of any reports received by Purchaser relating to any inspections
of the Property. Purchaser agrees to protect, indemnify, defend and hold Seller
harmless from and against any claim for liabilities, losses, costs, expenses
(including reasonable attorneys fees), damages or injuries arising out of or
resulting from the inspection of the Property by Purchaser or its agents or
consultants, and notwithstanding anything to the contrary in this Agreement,
such obligation to indemnify, defend and hold harmless shall survive Closing or
any termination of this Agreement.

         SECTION 3.2 Document Inspection. Seller shall make available (and copy
if requested) all of the following to Purchaser within five (5) days after the
Effective Date to the extent that such items are in the possession, custody or
control of Seller:

                  (a) copies of any environmental, physical condition, ADA and
other reports relating to the Property in Seller's possession;

                  (b) a list and complete copies of all Operating Agreements,
including any amendments and other documents pertaining hereto;

                  (c) plans, permits, specifications and certificates of
occupancy for the Real Property;

                  (d) all other reports, surveys, or other information
(including, without limitation, any notices with respect to the Property
received from any governmental agency) in Seller's possession relating to the
Property;

                  (e) the last 12 months utility bills and other operating
expenses for the Real Property;

                  (f) existing insurance policies for the Property;

                  (g) existing leases, licenses, permits and certificates
pertaining to the Property; and

                  (h) such other operating files maintained by Seller in
connection with the maintenance or management of the Property, including,
without limitation, insurance policies, bills, invoices, receipts and other
general records relating to the income and expense of the Property, but
excluding materials not directly relating to the maintenance and/or management
of the Property, such as, without limitation, Seller's internal memoranda,
financial projections, budgets, appraisals, accounting and tax records,
correspondence and documents to and from prospective purchasers and brokers, and
similar proprietary or confidential information.



         SECTION 3.3 Right of Termination. During the period beginning on the
Effective Date and ending at 5:00 p.m. (local time at the Property) on June 30,
2004 (the "Due Diligence Period"), if for any reason Purchaser, in its sole
discretion, determines that the Property or any aspect thereof is unsuitable for
Purchaser's acquisition, either Purchaser or Seller shall have the right to
terminate this Agreement by giving written notice thereof to the other, and if
such notice is given, this Agreement shall terminate. If this Agreement is
terminated pursuant to the foregoing provisions of this paragraph, then neither
party shall have any further rights or obligations hereunder (except for any
indemnity obligations of either party pursuant to the other provisions of this
Agreement), the Deposit shall be immediately returned to Purchaser without any
action being necessary, and each party shall bear its own costs incurred
hereunder. If Purchaser fails to give Seller a notice of termination prior to
the expiration of the Due Diligence Period, Purchaser shall be deemed to have
approved all aspects of the Property (except gap title issues governed by
Section 2.3 hereof) and to have elected to proceed with the purchase of the
Property pursuant to the terms hereof.

                                   ARTICLE IV

                                     CLOSING

         SECTION 4.1 Time and Place. The consummation of the transaction
contemplated hereby (the "Closing") shall be consummated within five (5)
business days of the date Purchaser, or its successor in interest, closes upon
its initial public offering, but not later than July 30, 2004, through an escrow
closing administered by Escrow Agent pursuant to joint instructions from Seller
and Purchaser. At the Closing, Seller and Purchaser shall perform the
obligations set forth in, respectively, Section 4.3 and Section 4.4 hereof, the
performance of which obligations shall be concurrent conditions. The Closing
shall be held at the offices of Escrow Agent set forth in Section 1.4. If the
sale transaction fails to Close by said date due to the extension of Purchaser's
public offering date, Purchaser shall have the option to extend the Closing Date
to the earlier of (i) five (5) business days after the date Purchaser, or its
successor in interest, closes upon its initial public offering, or (ii) October
16, 2004, by depositing with Escrow Agent an additional Fifty Thousand Dollars
($50,000) in good funds, either by certified bank or cashier's check or by
federal wire transfer. The Escrow Agent shall hold the deposit in an
interest-bearing account reasonably acceptable to Seller and Purchaser, in
accordance with the terms and conditions of this Agreement. All interest on such
sum shall be deemed income of Purchaser, and Purchaser and Seller shall pay all
costs and fees imposed on the deposit account. The deposit and all accrued
interest (collectively, the "Option Deposit") shall be distributed in accordance
with the terms of this Agreement.

         SECTION 4.2 If Purchaser is unable to execute its initial public
offering on or before October 16, 2004, Seller shall have the right to terminate
this Agreement without incurring any liability to Purchaser, and Purchaser's
Deposit and Option Deposit and all accrued interest thereon will be returned to
Purchaser. On the Closing, the Deposit, the Option Deposit, if any, and all
interest thereon shall be credited against the Purchase Price, and the balance
of the Purchase Price shall be paid by Purchaser to Seller through Escrow Agent
