                                   ARTICLE I

       1.1    Agreement of Purchase and Sale. Subject to the terms and
conditions hereinafter set forth, Seller agrees to sell and convey and Purchaser
agrees to purchase the following:

              (a)    that certain tracts or parcels of land located at 1200
Whipple Road, Union City, California and 1345 Doolittle Drive, San Leandro,
California, more particularly described on EXHIBIT A attached hereto and made a
part hereof, together with all and singular the rights and appurtenances
pertaining to such property, including any right, title and interest of Seller
in and to adjacent streets, alleys or rights-of-way (the property described in
clause (a) of this Section 1.1 being herein referred to collectively as the
"Land");

              (b)    the buildings, structures, fixtures and other improvements
on the Land, including, specifically, without limitation, two industrial

              (c)    all of Seller's right, title and interest in and to all
leases listed and described on EXHIBIT B (the "Lease Schedule") attached hereto
and made a part hereof, pursuant to which any portion of the Land or the
Improvements is used or occupied by anyone other than Seller (the property
described in clause (c) of this Section 1.1 being herein referred to

              (d)    all of Seller's right, title and interest in and to any

       1.2    Property Defined. The Land, the Improvements, the Leases and the
Intangibles are hereinafter sometimes referred to collectively as the
"Property."

       1.3    Permitted Exceptions. The Property shall be conveyed by grant deed
subject to the matters which are, or are deemed to be, Permitted Exceptions
pursuant to Article II hereof (herein referred to collectively as the "Permitted
Exceptions").

       1.4    Purchase Price. Seller is to sell and Purchaser is to purchase the
Property for a total of Twenty-Six Million Nine Hundred Twenty-Five Thousand
Dollars ($26,925,000) (the "Purchase Price").

       1.5    Payment of Purchase Price. The Purchase Price shall be paid as
follows:

              (a)    Within three (3) business days after the Effective Date (as
defined in Section 3.1 below), Purchaser shall deposit in escrow with First
American Title Company at 345 California Street, San Francisco, California,
attention: Virginia Bressman ("Title Company"), a deposit in the amount of Two
Hundred Fifty Thousand Dollars ($250,000) (the "Initial Deposit"). Unless
Purchaser has terminated this Agreement (or is deemed to have elected to
terminate this Agreement) pursuant to Section 3.1 below, Purchaser shall deposit
an additional Two Hundred Fifty Thousand Dollars ($250,000) (the "Final
Deposit") in escrow within two (2) business days after the expiration of the
Inspection Period described in 3.1 below. (The Initial Deposit and the Final
Deposit, if any, are collectively referred to herein as the "Deposit"). The
Deposit shall be held in an interest-bearing account and interest accruing
thereon shall be held for the account of Buyer subject to the terms hereof. In
the event the sale of the Property as contemplated hereunder is consummated, the
Deposit plus interest accrued thereon shall be credited against the Purchase
Price.

              (b)    The balance of Purchase Price, as increased or decreased by
prorations and adjustments as herein provided, shall be payable in full at
Closing through escrow (as hereinafter defined) in cash by wire transfer of
immediately available federal funds to a bank account designated by Seller in
writing to Purchaser prior to the Closing.

                                   ARTICLE II

                                TITLE AND SURVEY

       2.1    Title Examination; Commitment for Title Insurance. Purchaser shall
have until the expiration of the Inspection Period (defined in Section 3.1
hereof) to examine title to the Property. Purchaser will obtain from the Title
Company, at Purchaser's cost, a preliminary report (the "Title Commitment")
covering the Property, showing all matters affecting title to the Property.
Purchaser shall instruct the Title Company to deliver to Purchaser, Seller and
the surveyor described in Section 2.2 below copies of the Title Commitment and
copies of all instruments referenced therein.

       2.2    Survey. During the Inspection Period, Purchaser may, at
Purchaser's expense, employ a reputable surveyor or surveying firm, licensed by
the state in which the Property is located, to survey the Property and prepare
and deliver to Purchaser, the Title Company and Seller an ALTA survey thereof
(the "Survey") reflecting the total area of the Property, the



                                       2
   7

location of all improvements, recorded easements and encroachments, if any,
located thereon and all building and set back lines and other matters of record
with respect thereto.

       2.3    Title Objections; Cure of Title Objections. Purchaser shall have
until the expiration of the Inspection Period to notify Seller, in writing, of
such objections as Purchaser may have to anything contained in the Title
Commitment or the Survey. Any item contained in the Title Commitment or any
matter shown on the Survey to which Purchaser does not object during the
Inspection Period shall be deemed a Permitted Exception. In the event Purchaser
shall notify Seller of objections to title or to matters shown on the Survey
prior to the expiration of the Inspection Period, Seller shall have the right,
but not the obligation, to cure such objections. Within five (5) days after
receipt of Purchaser's notice of objections, Seller shall notify Purchaser in
writing whether Seller elects to attempt to cure such objections. If Seller
elects to attempt to cure, and provided that Purchaser shall not have terminated
this Agreement in accordance with Section 3.2 hereof, Seller shall have until
the date of Closing to attempt to remove, satisfy or cure the same and for this
purpose Seller shall be entitled to a reasonable adjournment of the Closing if
additional time is required, but in no event shall the adjournment exceed thirty
(30) days after the date for Closing set forth in Section 4.1 hereof. If Seller
elects not to cure any objections specified in Purchaser's notice, or if Seller
is unable to effect a cure prior to the Closing (or any date to which the
Closing has been adjourned), Purchaser shall have the following options: (i) to
accept a conveyance of the Property subject to the Permitted Exceptions,
specifically including any matter objected to by Purchaser which Seller is
unwilling or unable to cure, and without reduction of the Purchase Price; or
(ii) to terminate this Agreement by sending written notice thereof to Seller,
and upon delivery of such notice of termination, this Agreement shall terminate,
the Deposit shall be returned to Purchaser, and thereafter neither party hereto
shall have any further rights, obligations or liabilities hereunder except to
the extent that any right, obligation or liability set forth herein expressly
survives termination of this Agreement. If Seller notifies Purchaser that Seller
does not intend to attempt to cure any title objection, or if, having commenced
attempts to cure any objection, Seller later notifies Purchaser that Seller will
be unable to effect a cure thereof, Purchaser shall, within five (5) days after
such notice has been given, notify Seller in writing whether Purchaser shall
elect to accept the conveyance under clause (i) or to terminate this Agreement
under clause (ii).

       2.4    Conveyance of Title. At Closing, Seller shall convey and transfer
to Purchaser by grant deed such title to the Property as will enable the Title
Company to issue to Purchaser, at Purchaser's expense, an ALTA Owner's Policy of
title insurance (Form B, rev. 10/17/70) (the "Title Policy") covering the
Property, in the full amount of the Purchase Price with such endorsements
thereto as are reasonably requested by Purchaser. Notwithstanding anything
contained herein to the contrary, the Property shall be conveyed subject to the
following matters, which shall be deemed to be Permitted Exceptions:

              (a)    the rights of named tenants, as tenants only, under the
Leases and any new Leases entered into between the Effective Date (as
hereinafter defined) and Closing and, where required, approved by Purchaser in
accordance with the terms of this Agreement;

              (b)    the lien of all ad valorem real estate taxes and
assessments not yet due and payable as of the date of Closing;



                                       3
   8

              (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; and

              (d)    items appearing of record or shown on the Survey and, in
either case, not objected to by Purchaser or waived or deemed waived by
Purchaser in accordance with Sections 2.3 or 2.5 hereof.

       2.5    Pre-Closing "Gap" Title Defects. Whether or not Purchaser shall
have furnished to Seller any notice of title objections pursuant to the
foregoing provisions of this Agreement, Purchaser may, at or prior to Closing,
notify Seller in writing of any objections to title first raised by the Title
Company or the Surveyor between (a) the date which is the earlier of (i) the
effective date of Purchaser's Title Commitment referred to above or (ii) the
expiration of the Inspection Period and (b) the date on which the transaction
contemplated herein is scheduled to close. With respect to any objections to
title set forth in such notice, Seller shall have the same option to cure and
Purchaser shall have the same option to accept title subject to such matters or
to terminate this Agreement as those which apply to any notice of objections
made by Purchaser before the expiration of the Inspection Period. If Seller
elects to attempt to cure any such matters, the date for Closing shall be
automatically extended by a reasonable additional time to effect such a cure,
but in no event shall the extension exceed thirty (30) days after the date for
Closing set forth in Section 4.1 hereof.

                                  ARTICLE III

                                INSPECTION PERIOD

       3.1    Right of Inspection. During the period beginning on the date this
Agreement is fully executed by Seller and Purchaser (the "Effective Date") and
ending on October 26, 1998 (hereinafter referred to as the "Inspection Period"),
Purchaser shall have the right to make a physical inspection of the Property and
to examine at such place or places at the Property, in the offices of the
property manager or elsewhere as the same may be located, any operating files
maintained by Seller or its property manager in connection with the leasing,
maintenance and/or management of the Property, including, without limitation,
the Leases, lease files, Operating Agreements, insurance policies, bills,
invoices, receipts and other general records relating to the income and expenses
of the Property, operating budget, correspondence, surveys, plans and
specifications, warranties for services and materials provided to the Property,
engineering reports, environmental audits and similar materials, but excluding
materials not directly related to the leasing, maintenance and/or management of
the Property such as Seller's internal memoranda, financial projections,
appraisals, accounting and tax records and similar proprietary or confidential
information. Purchaser shall make all inspection requests in writing to Seller.
Each request shall include a list of information to be made available during
such inspection. Purchaser understands and agrees that any on-site inspections
of the Property shall be conducted upon at least twenty-four (24) hours' prior
notice to Seller and in the presence of Seller or its representative. To the
extent reasonably possible, Seller agrees to cooperate with all of Purchaser's
requests for Property information within two (2) business days from the receipt
thereof, provided that Seller shall not be required to furnish any information
excluded specifically by the terms of this Agreement. Purchaser agrees to repair
and restore any damage 



                                       4
   9

to the Property caused by any testing conducted on the Property by Purchaser.
Purchaser shall return the Property to substantially the same condition as
existed prior to its entry. Purchaser agrees to indemnify and defend Seller
against and hold Seller harmless from any claim for liabilities, costs, expenses
(including reasonable attorneys' fees actually incurred), damages or injuries to
the extent arising out of or resulting from the inspection of the Property by
Purchaser or its agents, excluding any liability arising out of pre-existing
conditions on the Property, and notwithstanding anything to the contrary in this
Agreement, such obligation to indemnify and hold harmless Seller shall survive
Closing or any termination of this Agreement. All inspections shall occur at
reasonable times agreed upon by Seller and Purchaser and shall be conducted so
as not to interfere unreasonably with use of the Property by Seller or its
tenants.

       3.2    Right of Termination. Seller agrees that in the event Purchaser
determines (such determination to be made in Purchaser's sole discretion) to
proceed with this transaction and purchase the Property, Purchaser shall make
such election by delivering to Seller written notice thereof prior to the
expiration of the Inspection Period, in which event Purchaser shall no longer
have any right to terminate this Agreement under this Section 3.2. If Purchaser
gives a notice of termination within the Inspection Period or fails to deliver
any notice within the Inspection Period, this Agreement shall terminate, the
Deposit shall be returned to Purchaser, and thereafter neither party shall have
any further rights, obligations or liabilities hereunder except to the extent
any right, obligation or liability set forth herein expressly survives
termination of this Agreement. Time is of the essence with respect to the
provisions of this Section 3.2.

                                   ARTICLE IV

                                     CLOSING

       4.1    Time and Place. The consummation of the transaction contemplated
hereby ("Closing") shall occur on November 10, 1998 (the "Closing Date"),
through Escrow No. SP282473 with the Title Company at 345 California Street, San
Francisco, California 94111. At Closing, Seller and Purchaser shall perform the
obligations set forth in Section 4.2 and Section 4.3, respectively, the
performance of which obligations shall be concurrent conditions.

       4.2    Seller's Obligations at Closing. At Closing, Seller shall:

              (a)    deliver to Purchaser a duly executed grant deed (the
"Deed") in recordable form, conveying the Land and the Improvements, subject
only to the Permitted Exceptions;

              (b)    assign to Purchaser, and Purchaser shall assume, the
landlord/lessor interest in and to the Leases by duly executed assignment and

hold Purchaser harmless from and against any and all claims pertaining to the
Leases arising prior to Closing and (ii) Purchaser shall indemnify Seller and
hold Seller harmless from and against any and all claims pertaining to the
Leases arising from and after the Closing, including, without limitation, claims
made by tenants with respect to tenants' security deposits to the extent paid,
credited or assigned to Purchaser;

              (c)    to the extent assignable, assign to Purchaser, and
Purchaser shall assume, Seller's interest in the Operating Agreements and the
other Intangibles by duly executed



                                       5
   10

assignment and assumption agreement pursuant to which (i) Seller shall indemnify

defined) as are in Seller's possession;

              (e)    join with Purchaser to execute a notice in form and content
reasonably satisfactory to Purchaser and Seller which Purchaser shall send to
each tenant under each of the Leases informing such tenant of the sale of the
Property and of the assignment to Purchaser of Seller's interest in, and
obligations under, the Leases (including, if applicable, any security deposits)
and directing that all rent and other sums payable after the Closing under each
such Lease shall be paid as set forth in the notice;

              (f)    deliver to Purchaser such evidence as the Title Company may
reasonably require as to the authority of the person or persons executing
documents on behalf of Seller;

              (g)    deliver to Purchaser an affidavit duly executed by Seller
stating that Seller is not a "foreign person" as defined in Section 1445 of the

              (h)    deliver to Purchaser the Leases, the Operating Agreements
and licenses and permits, if any, in the possession of Seller or Seller's
agents, together with such leasing and property files and records which are
material in connection with the continued operation, leasing and maintenance of
the Property. Purchaser shall cooperate with Seller for a period of seven (7)
years after Closing in case of Seller's need in response to any legal
requirement, a tax audit, tax return preparation or litigation threatened or
brought against Seller, by allowing Seller and its agents or representatives
access, upon reasonable advance notice (which notice shall identify the nature
of the information sought by Seller), at all reasonable times to examine and
make copies of any and all instruments files and records, which right shall
survive the Closing;

              (i)    deliver to Purchaser possession and occupancy of the
Property, subject to the Permitted Exceptions;

              (j)    deliver to Purchaser a California Form 590-RE Real Estate

increased or decreased by prorations and adjustments as herein provided, in
immediately available wire transferred funds pursuant to Section 1.5 above;



                                       6
   11

              (b)    join Seller in execution of the instruments described in
Sections 4.2(b), 4.2(c) and 4.2(e) above;

              (c)    deliver to Seller such evidence as the Title Company may
reasonably require as to the authority of the person or persons executing
documents on behalf of Purchaser; and

              (d)    deliver such additional documents as shall be reasonably
required to consummate the transaction contemplated by this Agreement.

       4.4    Credits and Prorations.

              (a)    The following shall be apportioned with respect to the
Property as of 12:01 a.m., on the day of Closing, as if Purchaser were vested
with title to the Property during the entire day upon which Closing occurs:

                     (i)    rents and other income, if any, as and when
       collected (the term "rents" as used in this Agreement includes all
       payments due and payable by tenants under the Leases);

                     (ii)   taxes and assessments levied against the Property;

                     (iii)  payments under the Operating Agreements;

                     (iv)   gas, electricity and other utility charges for which
       Seller is liable, if any, such charges to be apportioned at Closing on
       the basis of the most recent meter reading occurring prior to Closing;
       and

                     (v)    any other operating expenses or other items
       pertaining to the Property which are customarily prorated between a
       purchaser and a seller in the area in which the Property is located.

              (b)    Notwithstanding anything contained in the foregoing
provisions:

                     (i)    At Closing, (A) Seller shall, at Seller's option,
       either deliver to Purchaser any security deposits pursuant to the Leases
       or credit to the account of Purchaser the amount of such security
       deposits (to the extent such security deposits are not applied against
       delinquent rents or otherwise as provided in the Leases), and (B)
       Purchaser shall credit to the account of Seller all refundable cash or
       other deposits posted with utility companies serving the Property, or, at
       Seller's option, Seller shall be entitled to receive and retain such
       refundable cash and deposits.

                     (ii)   Any taxes and installments of special assessments
       which became payable prior to the Closing shall be paid by Seller prior
       to or as a part of the Closing. Taxes and assessments payable in tax year
       1998-1999 shall be prorated by Seller and Purchaser as of the day of
       Closing based upon the tax year.



                                       7
   12

                     (iii)  Charges referred to in Section 4.4(a) or in Section
       4.4(b)(ii) above, if any, which are payable by any tenant to a third
       party shall not be apportioned hereunder, and Purchaser shall accept
       title subject to any of such charges unpaid and Purchaser shall look
       solely to the tenant responsible therefor for the payment of the same. If
       Seller shall have paid any of such charges on behalf of any tenant, and
       shall not have been reimbursed therefor by the time of Closing, Purchaser
       shall pay to Seller such amounts as they are collected subsequent to
       Closing.

                     (iv)   Seller shall receive the entire advantage of any
       discounts for the prepayment by it of any taxes, water rates or sewer
       rents.

                     (v)    As to gas, electricity and other utility charges
       referred to Section 4.4(a)(iv) above, Seller may on notice to Purchaser
       elect to pay one or more or all of said items accrued to the date
       hereinabove fixed for apportionment directly to the person or entity
       entitled thereto, and to the extent Seller so elects, such item shall not
       be apportioned hereunder, and Seller's obligation to pay such item
       directly in such case shall survive the Closing.

                     (vi)   Unpaid and delinquent rent collected by Seller and
       Purchaser after the date of Closing shall be delivered as follows: (A) if
       Seller collects any unpaid or delinquent rent for the Property, Seller
       shall, within fifteen (15) days after the receipt thereof, deliver to
       Purchaser any such rent which Purchaser is entitled to hereunder relating
       to the date of Closing and any period thereafter, and (B) if Purchaser
       collects any unpaid or delinquent rent from the Property, Purchaser
       shall, within fifteen (15) days after the receipt thereof, deliver to
       Seller any such rent which Seller is entitled to hereunder relating to
       the period prior to the date of Closing. Seller and Purchaser agree that
       all rent received by Seller or Purchaser after the date of Closing shall
       be applied first to current rentals, and then to delinquent rentals, if
       any, in the order of their maturity. Purchaser will make a good faith
       effort after Closing to collect all rents in the usual course of
       Purchaser's operation of the Property, but Purchaser will not be
       obligated to institute any lawsuit or other collection procedures to
       collect delinquent rents. Where the Leases contain tenant obligations for
       taxes, common area expenses, operating expenses or additional charges of
       any other nature, and where Seller shall have collected any portion
       thereof in excess of amounts owed by Seller for such items for the period
       prior to the Closing Date, then, to the extent such amounts can be
       ascertained as of the Closing Date, there shall be an adjustment and
       credit given to Purchaser on the Closing Date for such excess amounts
       collected. Purchaser shall apply all such excess amounts to the charges
       owed by Purchaser for such items for the period after the Closing Date
       and, if required by the Leases, shall rebate or credit the tenants with
       any remainder. If expenses actually paid by Seller for such items during
       such period exceed the amounts actually collected by Seller which are
       attributable to such items, Purchaser shall pay to Seller an amount equal
       to such deficiency as and when such amounts are collected by Purchaser
       from the applicable tenants. If it is determined that the amount
       collected during Seller's ownership period exceeded expenses incurred
       during the same period by more than the amount previously credited to 
       Purchaser at Closing, then Seller shall promptly pay to Purchaser the 
       deficiency. If it is determined that the amount collected during Seller's
       ownership period exceeded expenses incurred during the same period by 
       less than the amount 



                                       8
   13

       previously credited to Purchaser at Closing, then Purchaser shall 
       promptly pay to Seller the difference.

                     (vii)  Seller and Purchaser shall jointly prepare a Closing
       statement of prorations on the basis of the Leases and other sources of
       income and expenses, and shall deliver such computation to the Title
       Company prior to Closing.

                     (viii) 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 said sum to the other party, together with interest thereon at the
       rate of two percent (2%) over the average "prime rate" (as announced from
       time to time in The Wall Street Journal) 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.

                     (ix)   The provisions of this Section 4.4 shall survive
       Closing.

                     (x)    Closing Costs. Seller shall pay (a) the fees of any
       counsel representing it in connection with this transaction; (b) the
       County transfer taxes; (c) 75% of the City of San Leandro transfer taxes
       (based on a purchase price of $15,000,000); and (d) 75% of the City of
       Union City transfer taxes (based on a purchase price of $11,925,000).
       Purchaser shall pay (t) the fees of any counsel representing Purchaser in
       connection with this transaction; (u) the escrow fee charged by the Title
       Company for the Closing; (v) the chain-of-title search; (w) the fees for
       recording the Deed conveying the Property to Purchaser; (x) the ALTA
       premium for the Title Policy; (y) 25% of the City of San Leandro transfer
       taxes (based on a purchase price of $15,000,000); and (z) 25% of the City
       of Union City transfer taxes (based on a purchase price of $11,925,000).
       All other costs and expenses incident to this transaction and the closing
       thereof shall be allocated in accordance with local custom.

       4.5    Conditions Precedent to Obligation of Purchaser. The obligation of
Purchaser to consummate the transaction hereunder shall be subject to the
fulfillment on or before the date of Closing of all of the following conditions,
any or all of which may be waived by Purchaser in writing in its sole
discretion:

              (a)    Seller shall have delivered to Purchaser all of the items
required to be delivered to Purchaser pursuant to the terms of this Agreement,
including, but not limited to, those provided for in Section 4.2.

              (b)    All of the representations and warranties of Seller
contained in this Agreement shall be true and correct in all material respects
as of the date of Closing (with appropriate modifications permitted under this
Agreement or not adverse to Purchaser).

              (c)    Seller shall have performed and observed, in all material
respects, all covenants and agreements of this Agreement to be performed and
observed by Seller as of the date of Closing.



                                       9
   14

              (d)    Seller shall have obtained and delivered to Purchaser a
tenant estoppel certificate in substantially the form of EXHIBIT D attached
hereto and made a part hereof ("Tenant Estoppels") from each of the tenants (the
"Tenants") in the buildings comprising the Improvements (and provided that in
the event that any Tenant Estoppel delivered to and accepted by Purchaser with
respect to any Lease shall contain any statement of fact, information or other
matter which is inconsistent with the matters stated in Seller's representations
in this Agreement, the Tenant Estoppel shall control and Seller shall have no
liability for any claim based upon a breach of representation regarding such
statement of fact, information or other matter contained in the Tenant
Estoppel). The Tenant Estoppels shall be substantially in the form of EXHIBIT D
(as modified to address specific concerns arising as a result of Purchaser's
review of the Leases) and shall be dated no earlier than thirty (30) days prior
to the Closing Date.

              (e)    The physical condition of the Property shall be
substantially the same on the day of Closing as of the last day of the
Inspection Period, reasonable wear and tear and loss by casualty excepted
(subject to the provisions of Article VII below), and, as of the day of Closing,
there shall be no litigation or administrative agency or other governmental
proceeding of any kind whatsoever, pending or threatened, which after Closing
would, in Purchaser's reasonable discretion, materially adversely affect the
value of the Property or the ability of Purchaser to operate the Property in the
manner in which it is currently being operated, and no proceedings shall be
pending or threatened which could or would cause the redesignation or other
modification of the zoning classification of, or of any building or
environmental code requirements applicable to, any of the Property.

       4.6    Conditions Precedent to Obligation of Seller. The obligation of
Seller to consummate the transaction hereunder shall be subject to the
fulfillment on or before the date of Closing of all of the following conditions,
any or all of which may be waived by Seller in its sole discretion: 

              (a)    Seller shall have received the Purchase Price as adjusted
pursuant to and payable in the manner provided for in this Agreement.

              (b)    Purchaser shall have delivered to Seller all of the items
required to be delivered to Seller pursuant to the terms of this Agreement,
including, but not limited to, those provided for in Section 4.3.

              (c)    All of the representations and warranties of Purchaser
contained in this Agreement shall be true and correct in all material respects
as of the date of Closing.

              (d)    Purchaser shall have performed and observed, in all
material respects, all covenants and agreements of this Agreement to be
performed and observed by Purchaser as of the date of Closing. 

                                   ARTICLE V

                         SELLER AND PURCHASER COVENANTS

       5.1    Covenants of Seller. Seller hereby covenants with Purchaser as
follows:

              (a)    From the Effective Date until the Closing or the earlier
termination of this Agreement, Seller shall use reasonable efforts to operate
and maintain the Property in a manner generally consistent with the manner in
which Seller has operated and maintained the Property prior to the date hereof.



                                       10
   15

              (b)    Seller shall use reasonable efforts (but without obligation
to incur any cost or expense) to obtain and deliver to Purchaser prior to
Closing, a written Tenant Estoppel substantially in the form of EXHIBIT D
attached hereto and made a part hereof signed by each Tenant under the Leases
occupying space in the Improvements.

              (c)    Seller shall not execute any renewal or expansion of an
existing Lease or any new Lease between the Effective Date and the date of
Closing without the prior written approval of Purchaser, which approval shall
not be unreasonably withheld.

              (d)    With respect to any Leases in existence as of the Effective
Date, Seller shall pay prior to Closing all landlord obligations, including,
without limitation, tenant improvement costs and leasing commissions. The
provisions of this Section 5.1(d) shall survive the Closing.

       5.2    Covenants of Purchaser. Purchaser hereby covenants with Seller
that Purchaser shall, in connection with its investigation of the Property
during the Inspection Period, inspect the Property for the presence of hazardous
substances, and shall furnish to Seller copies of any reports received by
Purchaser in connection with any such inspection. Purchaser shall also furnish
to Seller copies of any other reports received by Purchaser relating to any
other inspections of the Property conducted on Purchaser's behalf, if any
(including specifically, without limitation, any reports analyzing compliance of
the Property with the provisions of the Americans with Disabilities Act ("ADA"),
42 U.S.C. ss.12101, et seq., if applicable). Any reports furnished by Purchaser
to Seller shall be furnished without warranty of any kind whatsoever and shall
exclude any attorney-client privileged materials.

                                   ARTICLE VI

                                     DEFAULT

       6.1    Default by Purchaser. In the event the sale of the Property is not
consummated because of the failure of any Condition Precedent or any other
reason except a default under this Agreement on the part of Purchaser, the
Deposit plus interest accrued thereon shall immediately be returned to Purchaser
and neither party shall have any liability for obligations thereafter accruing
hereunder. If said sale is not consummated because of a default under this
Agreement on the part of Purchaser, the Deposit together with the interest
accrued thereon shall be paid to and retained by Seller as liquidated damages.
THE PARTIES HAVE AGREED THAT SELLER'S ACTUAL DAMAGES, IN THE EVENT OF A DEFAULT
BY PURCHASER, WOULD BE EXTREMELY DIFFICULT OR IMPRACTICABLE TO DETERMINE.
THEREFORE, BY PLACING THEIR INITIALS BELOW, THE PARTIES ACKNOWLEDGE THAT THE
DEPOSIT HAS BEEN AGREED UPON, AFTER NEGOTIATION, AS THE PARTIES' REASONABLE
ESTIMATE OF SELLER'S DAMAGES AND AS SELLER'S EXCLUSIVE REMEDY AGAINST PURCHASER,
AT LAW OR IN EQUITY, IN THE EVENT OF A DEFAULT UNDER THIS AGREEMENT ON THE PART
OF PURCHASER.

                        INITIALS:        Seller ________   Purchaser _______

       6.2    Default by Seller. In the event that Seller fails to consummate
this Agreement for any reason other than Purchaser's default or the permitted
termination of this Agreement by Seller or Purchaser as herein expressly
provided, Purchaser shall be entitled, as its sole remedy, either (a) to
terminate this Agreement and receive the Deposit and all interest thereon from
the Title Company, or (b) to enforce specific performance of Seller's obligation
to execute the documents required to convey the Property to Purchaser, it being
understood and agreed that the remedy of specific performance shall not be
available to enforce any other obligation of Seller hereunder. Purchaser
expressly waives its rights to seek damages in the event of Seller's default
hereunder. Purchaser shall be deemed to have elected to terminate this Agreement
if Purchaser fails to file suit for specific performance against Seller, in a
court having jurisdiction in the county and state in which the Property is
located, on or before sixty (60) days following the date upon which Closing was
to have occurred.

                                  ARTICLE VII

                                  RISK OF LOSS

       7.1    Minor Damage. In the event of loss or damage to the Property or
any portion thereof which is not "major" (as hereinafter defined), this
Agreement shall remain in full force and effect, provided Seller performs any
necessary repairs or, at Seller's option, assigns to Purchaser all of Seller's
right, title and interest to any claims and proceeds Seller may have with
respect to any casualty insurance policies or condemnation awards relating to
the premises in question. In the event that Seller elects to perform repairs
upon the Property, Seller shall use reasonable efforts to complete such repairs
promptly and the date of Closing shall be extended a reasonable time in order to
allow for the completion of such repairs. If Seller elects to assign a casualty
claim to Purchaser, the Purchase Price shall be reduced by an amount equal to
the deductible amount or uninsured loss under Seller's insurance policy. Upon
Closing, full risk of loss with respect to the Property shall pass to Purchaser.

       7.2    Major Damage. In the event of a "major" loss or damage, either
Seller or Purchaser may terminate this Agreement by written notice to the other
party. If neither Seller nor Purchaser elects to terminate this Agreement within
ten (10) days after Seller sends Purchaser written notice of the occurrence of
major loss or damage, then Seller and Purchaser shall be deemed to have elected
to proceed with Closing, in which event Seller shall, at Seller's option, either
(a) perform any necessary repairs, or (b) assign to Purchaser all of Seller's
right, title and interest to any claims and proceeds Seller may have with
respect to any casualty insurance policies or condemnation awards relating to
the premises in question. In the event that Seller elects to perform repairs
upon the Property, Seller shall use reasonable efforts to complete such repairs
promptly and the date of Closing shall be extended a reasonable time in order to
allow for the completion of such repairs. If Seller elects to assign a casualty
claim to Purchaser, the Purchase Price shall be reduced by an amount equal to
the deductible amount or uninsured loss under Seller's insurance policy. Upon
Closing, full risk of loss with respect to the Property shall pass to Purchaser.

       7.3    Definition of "Major" Loss or Damage. For purposes of Sections 7.1
and 7.2, "major" loss or damage refers to the following: (i) loss or damage to
the Property or any portion thereof such that the cost of repairing or restoring
the premises in question to a condition



                                       12
   17

substantially identical to that of the premises in question prior to the event
of damage would be, in the opinion of an architect selected by Seller and
reasonably approved by Purchaser, equal to or greater than One Hundred Thousand
Dollars ($100,000), and (ii) any loss due to a condemnation. If Purchaser does
not give notice to Seller of Purchaser's reasons for disapproving an architect
within five (5) business days after receipt of notice of the proposed architect,
Purchaser shall be deemed to have approved the architect selected by Seller.

                                  ARTICLE VIII

                                   COMMISSIONS

       8.1    Brokerage Commissions. In the event the transaction contemplated
by this Agreement is consummated, but not otherwise, Seller agrees to pay to
Colliers Parrish International, Inc. (the "Broker") at Closing a brokerage
commission pursuant to a separate written agreement between Seller and Broker.
Each party agrees that should any claim be made for brokerage commissions or
finder's fees by any broker or finder other than the Broker by, through or on
account of any acts of said party or its representatives, said party will
indemnify and hold the other party free and harmless from and against any and
all loss, liability, cost, damage and expense in connection therewith. The
provisions of this paragraph shall survive Closing.

                                   ARTICLE IX

                             DISCLAIMERS AND WAIVERS

       9.1    No Reliance on Documents. Except as expressly stated in this
Agreement, Seller makes no representation or warranty as to the truth, accuracy
or completeness of any materials, data or information delivered by Seller to
Purchaser in connection with the transaction contemplated hereby. Purchaser
acknowledges and agrees that all materials, data and information delivered by
Seller to Purchaser in connection with the transaction contemplated hereby are
provided to Purchaser as a convenience only and that any reliance on or use of
such materials, data or information by Purchaser shall be at the sole risk of
Purchaser, except as otherwise expressly stated herein. Without limiting the
generality of the foregoing provisions, Purchaser acknowledges and agrees that
(a) any environmental or other report with respect to the Property which is
delivered by Seller to Purchaser shall be for general informational purposes
only, (b) Purchaser shall not have any right to rely on any such report
delivered by Seller to Purchaser, but rather will rely on its own inspections
and investigations of the Property and any reports commissioned by Purchaser
with respect thereto, and (c) neither Seller, any affiliate of Seller nor the
person or entity which prepared any such report delivered by Seller to Purchaser
shall have any liability to Purchaser for any inaccuracy in or omission from any
such report.

       9.2    DISCLAIMERS. 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 WARRANTIES OR REPRESENTATIONS OF ANY KIND OR CHARACTER, EXPRESSED OR
IMPLIED, WITH RESPECT TO THE PROPERTY, INCLUDING, BUT NOT LIMITED TO, ANY
WARRANTIES OR REPRESENTATIONS AS TO HABITABILITY, MERCHANTABILITY, FITNESS FOR A

PROPERTY "AS IS, WHERE IS, WITH ALL FAULTS". EXCEPT TO THE EXTENT EXPRESSLY
PROVIDED OTHERWISE IN THIS AGREEMENT, PURCHASER HAS NOT RELIED AND WILL NOT RELY

       9.3    Effect and Survival of Disclaimers. Seller and Purchaser agree
that the provisions of this Article IX shall survive Closing.

                                   ARTICLE X

                                  MISCELLANEOUS

       10.1   Confidentiality. Purchaser and its representatives shall hold in
strictest confidence all data and information obtained with respect to Seller or
its business, whether obtained before or after the execution and delivery of
this Agreement, and shall not disclose the same to others; provided, however,
that it is understood and agreed that Purchaser may disclose such data and
information to (i) the employees, consultants, accountants and attorneys of
Purchaser, provided that such persons agree to treat such data and information
confidentially, or (ii) as required by law or any court having jurisdiction. In
the event this Agreement is terminated or Purchaser fails to perform hereunder,
Purchaser shall promptly return to Seller any statements, documents, schedules,
exhibits or other written information obtained from Seller in connection with
this Agreement or the transaction contemplated herein. It is understood and
agreed that, with respect to any provision of this Agreement which refers to the
termination of this Agreement, Purchaser shall fulfill its obligation to return
to Seller the materials described in the preceding sentence which were delivered
to Purchaser by Seller. In the event of a breach or threatened breach by
Purchaser or its agents or representatives of this Section 10.1, Seller shall be
entitled to an injunction restraining Purchaser or its agents or representatives
from disclosing, in whole or in part, such confidential information. Nothing
herein shall be construed as



                                       15
   20

prohibiting Seller from pursuing any other available remedy at law or in equity
for such breach or threatened breach.

       10.2   Public Disclosure. Prior to Closing, any release to the public of
information with respect to the sale contemplated herein or any matters set
forth in this Agreement will be made only in the form approved by Purchaser and
Seller and their respective counsel.

       10.3   Discharge of Obligations. The acceptance of the Deed by Purchaser
shall be deemed to be a full performance and discharge of every representation
and warranty made by Seller herein and every agreement and obligation on the
part of Seller to be performed pursuant to the provisions of this Agreement,
except those which are herein specifically stated to survive Closing.

       10.4   Assignment. Purchaser may not assign its rights under this
Agreement without first obtaining Seller's written approval, which approval may
be given or withheld in Seller's reasonable discretion. Under no circumstances
shall Purchaser have the right to assign this Agreement to any person or entity
owned or controlled by an employee benefit plan if Seller's sale of the Property
to such person or entity would, in the reasonable opinion of Seller's ERISA
advisor, create or otherwise cause a "prohibited transaction" under ERISA. In
the event Purchaser assigns this Agreement or transfers any ownership interest
in Purchaser without the consent of Seller, and such assignment or transfer
would make the consummation of the transaction hereunder a "prohibited
transaction" under ERISA and necessitate the termination of this Agreement,
then, notwithstanding any contrary provision which may be contained herein,
Seller shall have the right to pursue any remedy available at law or in equity
as a result of such assignment or transfer. Any transfer, directly or
indirectly, of any stock, partnership interest or other ownership interest in
Purchaser without Seller's written approval, which approval may be given or
withheld in Seller's reasonable discretion, shall constitute a default by
Purchaser under this Agreement. Notwithstanding anything to the contrary
contained in this Section 10.4, Purchaser shall have the right to assign its
rights and obligations hereunder to an affiliated assignee or nominee without
the consent of Seller. For purposes of the foregoing, "an affiliated assignee or
nominee" shall mean any person or entity that either: (i) directly owns at least
eighty percent (80%) of the legal and equitable ownership interests in Purchaser
or (ii) has at least eighty percent (80%) of its legal and equitable ownership
interests directly owned by Purchaser.

       10.5   Notices. Any notice pursuant to this Agreement shall be given in
writing by (a) personal delivery, or (b) reputable overnight delivery service
with proof of delivery, or (c) United States Mail, postage prepaid, registered
or certified mail, return receipt requested, or (d) legible facsimile
transmission sent to the intended addressee at the address set forth below, or
to such other address or to the attention of such other person as the addressee
shall have designated by written notice sent in accordance herewith, and shall
be deemed to have been given either at the time of personal delivery, or, in the
case of expedited delivery service or mail, as of the date of first attempted
delivery at the address and in the manner provided herein, or, in the case of
facsimile transmission, as of the date of the facsimile transmission provided
that an original of such facsimile is also sent to the intended addressee by
means described in clauses (a), (b) or (c) above. Unless changed in accordance
with the preceding sentence, the addresses for notices given pursuant to this
Agreement shall be as follows:

upon Purchaser unless and until Seller and Purchaser shall each execute and
deliver the same to the other. This Agreement shall not be binding in any way
upon Seller unless and until (a) Seller shall execute and deliver the same to
Purchaser, (b) each stage of Seller's investment approval process has approved
this transaction, and (c) Seller's Investment Committee has thereafter given its
written approval thereof. If Seller has not given Purchaser written notice (the
"Approval Notice") of such approvals on or before October 20, 1998 (the
"Approval Deadline"), or if prior to the Approval Deadline Seller notifies
Purchaser in writing that this Agreement has been disapproved by the persons or
entities referred to in clauses (b) or (c) of the preceding sentence, then this
Agreement shall be deemed terminated and Purchaser shall be entitled to the
return of the Deposit. It is understood and agreed that each stage of Seller's
investment approval process, Seller or its investment advisor, Lend Lease Real
Estate Investments, Inc., shall each have the right, in its unfettered
discretion, to disapprove the transaction contemplated by this Agreement for any
reason whatsoever, without obligation thereafter to proceed to the next stage of
Seller's investment approval process. Seller's approval of this Agreement shall
be evidenced only by 



                                       17
   22

both Seller's execution of this Agreement and Seller's sending of the Approval
Notice to Purchaser on or before the Approval Deadline, and, accordingly,
Purchaser acknowledges and agrees that Purchaser cannot and will not rely upon
any other statement or action of Seller or its representatives as evidence of
Seller's approval of this Agreement or the subject matter hereof.

       10.7   Modifications. This Agreement cannot be changed orally, and no
executory agreement shall be effective to waive, change, modify or discharge it
in whole or in part unless such executory agreement is in writing and is signed
by the parties against whom enforcement of any waiver, change, modification or
discharge is sought.

       10.8   Tenant Notification Letters. Purchaser and Seller shall deliver to
each and every tenant of the Property under a Lease thereof a signed statement
acknowledging Purchaser's receipt and responsibility for each tenant's security
deposit (to the extent delivered by Seller to Purchaser at Closing), if any, all
in compliance with and pursuant to the applicable provisions of applicable law.
The provisions of this paragraph shall survive Closing.

       10.9   Calculation of Time Periods. Unless otherwise specified, in
computing any period of time described in this Agreement, the day of the act or
event after which the designated period of time begins to run is not to be
included and the last day of the period so computed is to be included, unless
such last day is a Saturday, a Sunday or a legal holiday under the laws of the
State in which the Property is located, in which event the period shall run
until the end of the next day which is not a Saturday, a Sunday or a legal
holiday. The final day of any such period shall be deemed to end at 5 p.m.,
local time.

are to apply to and bind the permitted successors and assigns of the parties
hereto.

       10.11  Entire Agreement. This Agreement, including the Exhibits, contains
the entire agreement between the parties pertaining to the subject matter hereof
and fully supersedes all prior written or oral agreements and understandings
between the parties pertaining to such subject matter.

       10.12  Further Assurances. Each party agrees that it will without further
consideration execute and deliver such other documents and take such other
action, whether prior or subsequent to Closing, as may be reasonably requested
by the other party to consummate more effectively the purposes or subject matter
of this Agreement. Without limiting the generality of the foregoing, Purchaser
shall, if requested by Seller, execute acknowledgments of receipt with respect
to any materials delivered by Seller to Purchaser with respect to the Property.
The provisions of this Section 10.12 shall survive Closing.

       10.13  Counterparts. This Agreement may be executed in counterparts, and
all such executed counterparts shall constitute the same agreement. It shall be
necessary to account for only one such counterpart in proving this Agreement.

       10.14  Severability. If any provision of this Agreement is determined by

writing its intent to terminate its Lease prior to expiration of the term of the
Lease.

              (m)    No brokerage or similar fee is due or unpaid by Seller with

the actual knowledge of the Designated Employees (as hereinafter defined) of (i)
Lend Lease Real Estate Investments, Inc. ("Lend Lease"), and (ii) Compass

knowledge of Seller, or any affiliate of either of them, or to any other
officer, agent, manager, representative or employee of Seller or Lend Lease or
Compass or any affiliate thereof or to impose upon such Designated Employees any
duty to investigate the matter to which such actual knowledge, or the absence
thereof, pertains. As used herein, the term "Designated Employees" shall refer

defend and hold it harmless from and against any and all claims, demands,
liabilities, costs, expenses, penalties, damages and losses, including, without
limitation, reasonable attorneys' fees, resulting from any misrepresentation or
breach of warranty or breach of covenant made by such party in this Agreement or
