deposited with Escrow Agent pursuant to this Section 17 shall be added to and
become a part of the Earnest Money Deposit.

     18. ASSIGNMENT. This Agreement may not be assigned by Seller without the
prior written consent of Buyer which consent shall not be unreasonably withheld.
Buyer may assign its rights under this Agreement to an affiliate of Buyer
without seeking or obtaining Seller's consent. Such assignment shall not become
effective until the assignee executes an instrument whereby such assignee
expressly assumes each of the obligations of Buyer under this Agreement,
including specifically, without limitation, all obligations concerning the
Earnest Money Deposit. Buyer may also designate someone other than Buyer, as
grantee and/or assignee, under the Transfer Documents by providing written
notice of such designation at least five (5) days prior to COE. No assignment
shall release or otherwise relieve Buyer from any obligations hereunder.

     19. RISK OF LOSS. Seller shall bear all risk of loss, damage or taking of
the Property which may occur prior to COE. In the event of any loss, damage or
taking prior to COE, Buyer may, at Buyer's sole option, by written notice to
Seller and Escrow Agent, cancel this Agreement whereupon the Earnest Money
Deposit plus interest shall be paid immediately by Escrow Agent to Buyer and,
except as otherwise provided in this Agreement, neither of the Parties shall
have any further liability or obligation hereunder. In the alternative, Buyer
may attempt to negotiate an appropriate downward adjustment of the Price. If
Seller and Buyer cannot agree upon such a downward adjustment within a
reasonable period (not to exceed ten (10) days from the date Buyer receives
notice of the loss) Buyer may cancel this Agreement as provided above. If Buyer
waives any such loss or damage to the Property and closes escrow, Seller shall
at COE and as a condition precedent thereto, pay Buyer or credit Buyer against
the Additional Funds the amount of any insurance or condemnation proceeds, or
assign to Buyer, as of COE and in a form acceptable to Buyer, all rights or
claims for relief to the same.

     20. REMEDIES.

          (a) Seller's Breach. If Seller breaches this Agreement, Buyer may, at
Buyer's sole option, either: (i) by written notice to Seller and Escrow Agent,
cancel this Agreement whereupon the Earnest Money Deposit plus interest shall be
paid immediately by Escrow Agent to Buyer and, except as otherwise provided in
this Agreement, neither of the Parties shall have any further liability or
obligation hereunder; or, (ii) seek specific performance against Seller in which
event COE shall be automatically extended as necessary. Notwithstanding the
foregoing, if specific performance is unavailable as a remedy to Buyer because
of Seller's affirmative acts, Buyer shall be entitled to pursue all rights and
remedies available at law or in equity.

          (b) Buyer's Breach. If Buyer breaches this Agreement, as its sole
remedy Seller shall be entitled to retain the Earnest Money Deposit in
accordance with subsection 5(b) as Seller's agreed and total liquidated damages.
Seller hereby waives any right to seek any equitable or legal remedies against
Buyer.

     21. ATTORNEYS' FEES. If there is any litigation to enforce any provisions
or rights arising herein in accordance with Section 20(a), the unsuccessful
party in such litigation, as determined by the court, agrees to pay the
successful party, as determined by the court, all costs and expenses, including,
but not limited to, reasonable attorneys' fees incurred by the successful party,
such fees to be determined by the court.

     23. CLOSING COSTS.

          (a) Closing Costs. Seller and Buyer agree to pay closing costs as
indicated in this Agreement and in the escrow instructions attached hereto as
Exhibit F, and by this reference incorporated herein (the "Escrow
Instructions"). At COE, Seller shall pay (i) the costs of releasing all liens,
judgments, and other encumbrances that

<PAGE>

are to be released and of recording such releases, (ii) the fees and costs due
Escrow Agent for its services, (iii) the transfer tax associated with the sale
of the Property, if any, and (iv) all other costs to be paid by Seller under
this Agreement. Except as otherwise provided for in this Agreement, Seller and
Buyer will each be solely responsible for and bear all of their own respective
expenses, including, without limitation, expenses of legal counsel, accountants,
and other advisors incurred at any time in connection with pursuing or
consummating the transaction contemplated herein. Real estate taxes shall be
prorated based upon the current valuation and latest available tax rates. All
prorations shall be calculated through escrow as of COE based upon the latest
available information, including, without limitation, a credit to Buyer for any
rent prepaid by Tenant for the period beginning with and including the date on
which the closing occurs through and including the last day of the month in
which the closing occurs. All other credits to Buyer shall be similarly
prorated. Any other closing costs not specifically designated as the
responsibility of either Party in the Escrow Instructions or in this Agreement
shall be paid by Seller and Buyer according to the usual and customary
allocation of the same by Escrow Agent. Seller agrees that all closing costs
payable by Seller shall be deducted from Seller's proceeds otherwise payable to
Seller at COE. Buyer shall deposit with Escrow Agent sufficient cash to pay all
of Buyer's closing costs. Except as provided in this Section 23(a), Seller and
Buyer shall each bear their own costs in regard to this Agreement.

          (b) Post-Closing Adjustment. If after COE, the parties discover any
errors in adjustments and apportionments or additional information becomes
available which would render the closing prorations materially inaccurate, the
same shall be corrected as soon after their discovery as possible. The provision
of this Section 23(b) shall survive COE except that no adjustment shall be made
later than two (2) months after COE unless prior to such date the Party seeking
the adjustment shall have delivered a written notice to the other Party
specifying the nature and basis for such claim. In the event that such claim is
valid, the Party against whom the claim is sought shall have ten (10) days in
which to remit any adjustment due.

          (c) Instructions. This Agreement, together with the Escrow
Instructions, shall constitute escrow instructions for the transaction
contemplated herein. Such escrow instructions shall be construed as applying
principally to Escrow Agent's employment.

     24. ESCROW CANCELLATION CHARGES. If escrow fails to close because of
Seller's default, Seller shall be liable for any cancellation charges of Escrow
Agent. If escrow fails to close because of Buyer's default, Buyer shall be
liable for any cancellation charges of Escrow Agent. If escrow fails to close
for any other reason, Seller and Buyer shall each be liable for one-half of any
cancellation charges of Escrow Agent. The provisions of this Section 24 shall
survive cancellation of this Agreement.

     25. APPROVALS. Concerning all matters in this Agreement requiring the
consent or approval of any Party, the Parties agree that any such consent or
approval shall not be unreasonably withheld unless otherwise provided in this
Agreement.

     26. RELEASES. Except as expressly provided in this Agreement, Seller and
anyone claiming through Seller hereby releases Tenant from any and all claims of
whatever kind or nature, in law or equity, whether now known or unknown to
Seller, whether contingent or matured, that Seller may now have or hereafter
acquire against Tenant for any costs, loss, liability, damage, expenses, demand,
action or cause of action arising from or related to the Lease arising from
events occurring prior to COE.

     27. ADDITIONAL ACTS. The Parties agree to execute promptly such other
documents and to perform such other acts as may be reasonably necessary to carry
out the purpose and intent of this Agreement.

     28. GOVERNING LAW/JURISDICTION/VENUE. This Agreement shall be governed by

District of Arizona in Phoenix and in the Superior Court of Arizona in Maricopa
County, Arizona.

     29. CONSTRUCTION. The terms and provisions of this Agreement represent the
results of negotiations among the Parties, each of which has been represented by
counsel of its own choosing, and neither of which has acted under any duress or
compulsion, whether legal, economic or otherwise. Consequently, the terms

<PAGE>

and provisions of this Agreement shall be interpreted and construed in
accordance with their usual and customary meanings, and the Parties each hereby
waive the application of any rule of law which would otherwise be applicable in
connection with the interpretation and construction of this Agreement that
ambiguous or conflicting terms or provisions contained in this Agreement shall
be interpreted or construed against the Party whose attorney prepared the
executed Agreement or any earlier draft of the same.

     30. TIME OF ESSENCE. Time is of the essence of this Agreement. However, if
this Agreement requires any act to be done or action to be taken on a date which
is a Saturday, Sunday or legal holiday, such act or action shall be deemed to
have been validly done or taken if done or taken on the next succeeding day
which is not a Saturday, Sunday or legal holiday, and the successive periods
shall be deemed extended accordingly.

     31. INTERPRETATION. If there is any specific and direct conflict between,
or any ambiguity resulting from, the terms and provisions of this Agreement and
the terms and provisions of any document, instrument or other agreement executed
in connection herewith or in furtherance hereof, including any Exhibits hereto,

are fully incorporated herein as though set forth at length herein.

     35. SEVERABILITY. If any provision of this Agreement is unenforceable, the
remaining provisions shall nevertheless be kept in effect.

     36. ENTIRE AGREEMENT. This Agreement contains the entire agreement between
the Parties and supersedes all prior agreements, oral or written, with respect
to the subject matter hereof. The provisions of this Agreement shall be
construed as a whole and not strictly for or against any Party.

     37. SEC S-X 3-14 Audit. Seller acknowledges that Buyer may elect to assign
all of its right, title and interest in and to this Agreement to a company that
is subject to the reporting requirements of the Securities Exchange Act of 1934,
as amended ("Registered Company"), promoted by the Buyer or to an affiliate of a
Registered Company (a "Registered Company Affiliate"). In the event Buyer's
assignee under this Agreement is a Registered Company or a Registered Company
Affiliate, the Registered Company will be required to make certain filings with
the U.S. Securities and Exchange Commission required under SEC Rule 3-14 of
Regulation S-X (the "SEC Filings") that relate to the most recent
pre-acquisition fiscal year (the "Audited Year") for the Property. To assist the
Registered Company with the preparation of the SEC Filings, Seller agrees to
provide Buyer and the Registered Company with financial information regarding
the Property for the Audited Year requested by Buyer, the Registered Company,
and/or Buyer's or the Registered Company's auditors. Such information may
include, but is not limited to, bank statements, operating statements, general
ledgers, cash receipts schedules, invoices for expenses and capital
improvements, insurance documentation, and accounts receivable aging related to
the Property ("SEC Filing Information"). Seller shall deliver the SEC Filing
Information requested by Buyer, the Registered Company and/or Buyer's or the
Registered Company's auditors prior to the expiration of the Study Period, and
Seller agrees to cooperate with Buyer, the Registered Company and Buyer's or the
Registered Company's auditors regarding any inquiries by Buyer, the Registered
Company and Buyer's or the Registered Company's auditors following receipt of
such information, including delivery by Seller of an executed representation
letter prior to COE in form and substance requested by Buyer's or the Registered
Company's auditors ("SEC Filings Letter"). A sample SEC Filings Letter is
attached to the Purchase Agreement as Exhibit G; however, Buyer's and/or the
Registered Company's auditors may require additions and/or revisions to such
letter following review of the SEC Filing Information provided by Seller. Seller
consents to the disclosure of the SEC Filing Information in any SEC Filings

<PAGE>

by the Registered Company. Buyer shall reimburse Seller for Seller's reasonable
costs associated with providing the SEC Filing Information. The provisions of
this Section 37 shall survive the COE for a period of one (1) year.

               [REMAINDER OF THIS PAGE INTENTIONALLY LEFT BLANK.]

     IN WITNESS WHEREOF, Seller and Buyer have executed this Agreement as of the
Effective Date.
