            C.    all improvements and fixtures located on the Real Property
(collectively, the "Improvements");

            D.    all personal property owned by Seller located on or in the
Real Property and Improvements including, without limitation, those items
described in attached Exhibit A-2 (the "Personal Property"); and

            E.    any intangible personal property now owned by Seller which is
used in the ownership, use or operation of the Real Property, Improvements or
Personal Property, including, without limitation, reports, warranties,
indemnities, permits, plans, insurance proceeds and condemnation awards, if any
(collectively, the "Intangible Property"). Upon execution of this Agreement,
Seller shall provide Buyer all contracts, plans, surveys, studies, reports,
budgets, warranties, indemnities, permits, utility contracts or other agreements
or rights relating to the ownership, use and operation of the Property.

            All of the items referred to above are collectively referred to as

      2.    Purchase Price. The purchase price of the Property is Eight Million
Five Hundred Thousand Dollars ($8,500,000), payable in cash at the closing of
the purchase and sale contemplated hereunder (the "Closing"). In addition, Buyer
will assume (or, at its election, pay off) the loan secured by the Property in a
principal amount not to exceed Three Million One Hundred Seventy-Nine Thousand
Seventy-Eight Dollars and 71/100 ($3,179,078.71) (the "Loan") from Institutional
Commercial Mortgage Fund IV, f/k/a Westmark Commercial Mortgage Fund IV

                                       1
<PAGE>
            A.    At the Closing, Seller shall convey to Buyer fee simple title
to the Real Property, the Appurtenances and the Improvements, by duly executed
and acknowledged grant deed substantially in the form of attached Exhibit B (the
"Deed"). As a condition to Buyer's obligation to consummate the purchase of the
Property, Chicago Title Company (the "Title Company") shall be unconditionally
committed to issue to Buyer an ALTA Owner's Policy of Title Insurance (Form B,
rev. 10/17/70) (the "Title Policy") in the amount of the Purchase Price (or such
lower amount as Buyer may determine), at no more than the Title Company's
standard rates, insuring fee simple title to the Real Property, the
Appurtenances and the Improvements in Buyer, subject only to the Loan (if Buyer
has not prepaid the Loan) and the Permitted Exceptions set forth on Exhibit C
attached hereto. The Title Policy shall provide full coverage against mechanics'
and materialmen's liens arising out of the construction, repair or alteration of
any of the Improvements including any tenant improvements therein (other than
those performed by Buyer) and shall contain such endorsements as Buyer may
reasonably require (the "Endorsements").

            B.    At the Closing, Seller shall transfer to Buyer all of Seller's
right, title and interest in the Personal Property and the Intangible Property
(if any) by a Bill of Sale and Assignment of Intangible Property in the form
attached hereto as Exhibit D (the "Bill of Sale"), such right, title and
interest, if any, to be free of any liens, encumbrances or interests arising by,
through or under Seller (other than any liens held by the Lender).

      4.    Loan Assumption. Through the Closing, Seller will in good faith
attempt to negotiate with Lender to reduce the prepayment fees under the Loan
and will cooperate reasonably with Buyer's efforts to assume or prepay the Loan.
Seller represents that the outstanding balance of the Loan is no more than Three
Million One Hundred Seventy-Nine Thousand Seventy-Eight Dollars and 71/100
($3,179,078.71) and that there are no contracts (other than the Loan and
Permitted Exceptions, if any) that will affect the Property or be binding upon
Buyer on or after the Closing. Seller will not default under the Loan or cause
it to be accelerated.

      5.    Closing and Escrow.

            A.    The Closing will occur on a business day (the "Closing Date"),
identified by Buyer, on or before September 12, 2003. If the Closing fails to
occur by September 12, 2003, for any reason other than Seller's default
hereunder, this Agreement shall terminate and Seller shall have the right to
exercise all of its rights and remedies as set forth in the Lease (as
hereinafter defined) (including, without limitation, the collection of rent
under the Lease for August and September 2003, the collection of late fees,
attorneys' fees, and interest as permitted under the Lease and the drawing of
the LC Security Deposit (as defined in the Lease) as permitted under the Lease).
In the event the Closing fails to occur as a result of Seller's default
hereunder, Buyer may exercise any remedy available at law or in equity, or avail
itself of any combination of the foregoing.

            B.    Upon mutual execution of this Agreement, the parties hereto
shall deposit an executed counterpart of this Agreement with the Title Company
and this Agreement shall serve as instructions to the Title Company (as the
escrow holder for consummation of the purchase and sale contemplated hereby).
Seller and Buyer agree to execute such additional escrow instructions as may be
appropriate to enable the Title Company to comply with the terms of this
Agreement. All documents to be delivered at the Closing and all payments to be
made under this Agreement shall be delivered into escrow with the Title Company.
It is a condition to each party's obligations hereunder to proceed to Closing
and to consummate the transactions contemplated hereby, that, as of the Closing
Date, the other party has performed all of such party's obligations under this
Agreement in all material respects.

            C.    At or before the Closing, Seller shall deliver to Buyer the
following documents:

                  (i)   a duly executed and acknowledged Deed;

                        indemnities, utility contracts or other agreements or
                        rights relating to the ownership, use and operation of
                        the Property, if any;

                  (vi)  an Affidavit of Non-Foreign Status in form attached
                        hereto as Exhibit E and California Form 593-C duly

Affidavit reasonably acceptable to the Title Company.

            F.    The following are to be apportioned as of the Closing Date, as
follows:

                  (i)   Real Estate Taxes/Insurance/Loan Payments. General real
estate taxes payable for all tax years ending prior to the Closing Date shall be
paid by Seller. General real estate taxes payable for the tax year containing
the Closing Date shall be prorated between Seller and Buyer as of the Closing

(defined below) shall be prorated between Seller and Buyer as of the Closing
Date.

                  (ii)  Post-Closing Reconciliation. If any of the aforesaid
prorations cannot be calculated accurately on the Closing Date, then they shall
be calculated as soon after the Closing Date as feasible. Either party owing the
other party a sum of money based on such subsequent proration(s) shall promptly
pay such sum to the other party, together with interest thereon at the rate of
eight percent (8%) per annum from the Closing Date to the date of payment if
payment is not made within ten (10) days after delivery of a bill therefor.

                  (iii) Survival. The provisions of this Section 5.F shall
survive the Closing.

            G.    Buyer shall pay all transfer taxes, survey fees, escrow fees
and title insurance premiums in connection with its purchase of the Property
under this Agreement.

      6.    Lease.

            A.    Payment of Interest, Late Fees, etc. In addition to the
Purchase Price and the Carrying Costs, Buyer will pay to Seller at Closing
Twenty-Seven Thousand Two Hundred Twenty-Eight Dollars ($27,228) (the "Lease
Charges") in satisfaction of Buyer's obligation to pay all interest, late fees,
attorneys' fees, penalties and all other charges due under the Lease.

            B.    Lease Termination and Release. Upon the Closing, that certain
Standard Industrial/Commercial Single-Tenant Lease-Net dated September 13, 2000
and the First Addendum to Standard Industrial/Commercial Single-Tenant Lease-Net
of the same date between Seller, as Lessor, and Buyer (then known as Western
Multiplex Corporation), as Lessee (collectively, the "Lease") will terminate,
and Seller and Buyer will fully release each other from any and all past,
present and future claims, damages, and liabilities, both known and unknown,
that the releasing party has or may have against the other party which relate in
any manner to the Lease, subject to Section 6.C of this Agreement and as
otherwise provided in the Lease Termination (defined below). At the Closing,
Seller will return to Buyer the entire LC Security Deposit under the Lease in
the amount of One Million Five Hundred Thousand Dollars ($1,500,000) and the
entire Cash Security Deposit (as defined in the Lease) in the amount of Two
Million Five Hundred Thousand Dollars ($2,500,000). Buyer will have no
obligation to pay rent under the Lease (subject, however, to Section 6.D of this
Agreement), and Seller will not draw upon the LC Security Deposit or the Cash
Security Deposit, terminate the Lease, sue Buyer under the Lease or take any
other adverse action against Buyer relating in any manner to the Lease, from and
after July 21, 2003 while the purchase of the Property is pending hereunder.
Upon the Closing, Buyer and Seller shall execute a Lease Termination and Release
Agreement in the form attached hereto as Exhibit F (the "Lease Termination").

            C.    Bankruptcy. Buyer and Seller acknowledge and agree that (i)
Seller's unencumbered retention upon the Closing of the funds to be paid
hereunder is a material inducement to Seller to enter into this Agreement and
(ii) in the event that the payment of such money or this Agreement should for
any reason subsequently be declared to be "fraudulent" within the meaning of any
state, federal or foreign law relating to fraudulent conveyances, preferential
or otherwise voidable or recoverable, in whole or in part, for any reason, under

                                       4
<PAGE>
the United States Bankruptcy Code or any other federal, foreign or state law as
part of a bankruptcy by Buyer (collectively referred to herein as "Voidable
Transfer"), and Seller is required to pay or restore any such Voidable Transfer,
or any portion thereof, then (a) Seller's release set forth above shall
terminate to the extent required to enforce clause (b) below, and (b) the full
amount of the obligations due under the Lease shall be due and payable as if no
compromise or release had occurred, provided, however, Seller shall in no event
be entitled to recover in the aggregate an amount greater than the amounts
required to be paid by Buyer under this Agreement (excluding Sections 5.A and
6.C and less the Cash Security Deposit returned to Buyer).

            D.    Carrying Costs. Buyer will pay, at the Closing, the following
to the extent applicable to the period beginning August 1, 2003 and ending on
the Closing (collectively, the "Carrying Costs"): (i) Seller's monthly principal
and interest payments under the Loan (the "Loan Payments"); (ii) "Real Property
Taxes" under the Lease; and (iii) insurance premiums under the Lease.

      7.    Condition of Property. The Property is being purchased by Buyer in
its "AS IS" condition without representation or warranty (except as expressly
set forth herein) or indemnity by Seller.

      8.    Environmental. To Seller's knowledge, no Hazardous Substances (as
defined in the Lease) exist on or under the Property except as disclosed in the
reports and tests previously provided to Buyer.

      9.    Authority.

            A.    Seller hereby represents and warrants to and covenants with
Buyer that (i) this Agreement and all documents executed by Seller which are to
be delivered to Buyer at the Closing are and at the time of Closing will be duly
authorized, executed and delivered by Seller, are and at the time of Closing
will be legal, valid and binding obligations of Seller enforceable against
Seller in accordance with their respective terms subject to bankruptcy laws and
principles of equity applying to landlords, tenants and creditors generally, are
and at the time of Closing will be sufficient to convey title (if they purport
to do so), and do not and at the time of Closing will not violate any provision
of any agreement or judicial order to which Seller or the Property is subject;
(ii) Seller is the legal and equitable owner of the Property, with full right to
convey the same, and without limiting the generality of the foregoing, Seller
has not granted any option or right of first refusal or first opportunity to any
party to acquire any interest in any of the Property; and (iii) Seller is not a
"foreign person" within the meaning of Section 1445(f)(3) of the Internal
Revenue Code, and the Purchase Price payable to Seller is not subject to
withholding under U.S. tax law. The Purchase Price, however, shall be subject to
all withholding laws of the State of California, and Buyer shall have the right
to withhold, through the Title Company as withholding agent, such portion of the
Purchase Price as may be necessary, in the opinion of Buyer or its counsel, to
comply with California Revenue and Taxation Code Section 18662 as revised by
Assembly Bill 2065 (Chapter 02-488).

            B.    Buyer hereby represents and warrants to Seller that this
Agreement and all documents executed by Buyer which are to be delivered to
Seller at the Closing are or at the time of Closing will be duly authorized,
executed and delivered by Buyer, and are or at the Closing will be legal, valid
and binding obligations of Buyer enforceable against Buyer in accordance with
their respective terms subject to bankruptcy laws and principles of equity
applying to landlords, tenants and creditors generally, and do not and at the
time of Closing will not violate any provisions of any agreement or judicial
order to which Buyer is subject.

      10.   Casualty/Condemnation. If, before the Closing, the Property is
damaged by casualty and the cost to repair exceeds One Hundred Thousand Dollars
($100,000) or condemnation proceedings are commenced against any of the
Property, Buyer may elect to terminate this Agreement by delivery of written
notice thereof to Seller. If Buyer elects not to terminate this Agreement, (i)
at Closing, Seller will assign all insurance and condemnation proceeds to Buyer,
(ii) Seller shall not compromise, settle or adjust any claims to such proceeds
without Buyer's


                                       5
<PAGE>
prior written consent and (iii) Seller shall cooperate with Buyer in obtaining
such insurance and condemnation proceeds. If Buyer elects not to terminate this
Agreement and proceeds to the Closing, upon the Closing, Buyer waives and
relinquishes any right or claim it has or may have against Seller related to any
damage to the Property by casualty or the condemnation proceeding except with
respect to Seller's express obligations in the preceding sentence.

      11.   Buyer's Consent to New Contracts Affecting the Property; Termination
of Existing Contracts.

            A.    Seller shall not, after the date of Seller's execution of this
Agreement, enter into any lease or contract with respect to the Property, or any
amendment thereof, without in each case obtaining Buyer's prior written consent
thereto, which consent may be withheld in Buyer's sole discretion.

            B.    Seller shall terminate, prior to the Closing, at no cost or
expense to Buyer, any and all management agreements and other contracts
affecting the Property, except as approved by Buyer in writing.

      12.   Insurance; Maintenance. Through the Closing Date, Seller shall
maintain or cause to be maintained, subject to Section 6.D of this Agreement,

in the condition existing as of the Effective Date and shall deliver the
Property to Buyer at Closing in such condition.

      13.   Cooperation. Buyer and Seller will execute and deliver any
instruments or other documents reasonably necessary to effect the purchase and
sale transaction described in this Agreement.

      14.   Confidentiality: Seller shall keep all information about this
purchase transaction strictly confidential and will not disclose any such
information to any other person or entity without first obtaining the prior
written consent of Buyer.

      15.   Miscellaneous.

to the other.

            B.    Brokers. The parties hereto each represent to the other that
they have dealt with no real estate brokers, finders, agents or salesmen in
connection with this transaction other than David Mein of Colliers Parrish,
representing Seller, and Scott Daugherty of Strategic Realty Advisors,
representing Buyer. Except with respect to attorneys' fees under the Lease as

heirs, administrators and assigns. Buyer shall have the right, to assign its
right, title and interest in and to this Agreement to one or more assignees at
any time before the Closing Date upon Seller's written consent, which consent
shall not be unreasonably withheld. Seller's consent to an assignment of this
Agreement to one or more assignees will not relieve or release Buyer of its
obligations to Seller under this Agreement or the Lease Termination. Buyer may,
however, without Seller's consent (and without constituting an assignment of
this Agreement and without releasing Buyer of its obligations to Seller under
this Agreement or the Lease Termination), designate an affiliate of Buyer to be
the party taking title to the Property pursuant to this Agreement.

            D.    Amendments. Except as otherwise provided herein, this
Agreement may be amended or modified only by a written instrument executed by
Seller and Buyer.

            E.    Continuation and Survival of Representations and Warranties.
The representations and warranties by the respective parties contained in this
Agreement are intended to and shall remain true and correct as of the time of
Closing, shall be deemed to be material, and shall survive the execution and
delivery of this Agreement and the Closing.

            F.    Governing Law. This Agreement shall be governed by and
construed in accordance with the laws of the State of California.

            G.    Merger of Prior Agreements. This Agreement and the exhibits
hereto constitute the entire agreement between the parties and supersede all
prior agreements and understandings between the parties relating to the subject
matter hereof, including the letter agreement dated July 21, 2003 between the
parties.

            H.    Enforcement. In the event a dispute arises concerning the
performance, meaning or interpretation of any provision of this Agreement, the
defaulting party or the party not prevailing in such dispute shall pay any and
all costs and expenses incurred by the other party in enforcing or establishing
its rights hereunder, including, without limitation, court costs and attorneys'
fees.

            I.    Time of the Essence. Time is of the essence of this Agreement.

                                       7
<PAGE>
            J.    Severability. If any provision of this Agreement, or the
application thereof to any person, place, or circumstance, shall be held by a
court of competent jurisdiction to be invalid, unenforceable or void, the
remainder of this Agreement and such provisions as applied to other persons,
places and circumstances shall remain in full force and effect.

            K.    1031 Exchange. The parties acknowledge that Seller may wish to
consummate the sale of the Property through a qualified tax-deferred exchange
under Section 1031 of the Internal Revenue Code. In such event, Buyer will
cooperate reasonably with Seller in such efforts, provided such exchange will be
