                         AGREEMENT OF PURCHASE AND SALE
                          AND JOINT ESCROW INSTRUCTIONS


To:      Commerce Escrow Company                Escrow No. 96-25237-MM 1545
         Wilshire Boulevard, Suite 600          Escrow Officer: Mr. Mark Minsky
         Los Angeles, California 90017


         THIS AGREEMENT OF PURCHASE AND SALE AND JOINT ESCROW INSTRUCTIONS
("Agreement") is made and entered into as of the 3rd day of October, 1996 (the
"Effective Date"), by and between 10960 PROPERTY CORPORATION, a Delaware
corporation ("Seller"), and BEACON PROPERTIES, L.P., a Delaware limited
partnership ("Buyer").


                                    RECITALS:


         A. The property being sold pursuant to this Agreement (collectively,
the "Property") consists of (i) the fee interest in the land located at 10960
Wilshire Boulevard, Los Angeles, California and more particularly described on
Exhibit "A" attached hereto, together with all easements, rights-of-way,
privileges and appurtenances pertaining thereto, including any right, title and
interest of Seller in and to any street adjoining any portion thereof
(collectively, the "Land"); (ii) all of Seller's right, title and interest
(including the fee interest) in and to all structures, buildings, fixtures,
parking facilities, landscaping and other improvements currently constructed and
located on the Land, as well as any addition; to or replacements of same
occurring following the Effective Date, together with all machinery and
mechanical, electrical, HVAC and plumbing systems used in the operation thereof,
but excluding any such items owned by tenants, public or private utilities,
contractors under contract or other third parties (the "Improvements", which
Improvements together with the Land are hereinafter collectively referred to as
the "Real Property"), (iii) all of Seller's right, title and interest in and to
all equipment, appliances, tools, machinery, supplies, building materials,
furniture, artwork, and other tangible personal property located at the Real
Property and used exclusively in the ownership, management, operation or
marketing thereof, to the extent listed on Exhibit "B" attached hereto (the
"Tangible Personal Property"); (iv) all of Seller's right, title and interest in
and to all Intangible personal property used exclusively in the ownership,
management, operation or marketing of the Real Property, including all
transferable licenses, permits, certificates of occupancy, trade names,
trademarks, service marks, logos and other marks used by Seller in the operation
and identification of the Real Property, all building plans and specifications
regarding the Improvements which are in the possession of Seller, and any and
all service contracts, maintenance agreements, construction contracts,
architects agreements, parking agreements, warranties, guaranties, and other
contracts and agreements relating exclusively to the Real Property which by the



express terms thereof are assignable without the consent of any third party and
which continue following the Close of Escrow (as defined below), to the extent
same are described on Exhibit "C" attached hereto (the "Intangible Personal
Property"), and (v) all written or oral agreements granting any party the right
to use or occupy any portion of the Real Property (the "Leases"), together with
any security deposits and other deposits held by or under the control of Seller
or Seller's property manager and leasing agent, Hines Interests Limited
Partnership ("Seller's Agent") as of the Close of Escrow with respect to the
Leases (collectively, the "Tenant Deposits"). A schedule of the Tenant Deposits
as of the Effective Date is attached hereto as Exhibit "D".

         B. Seller and Seller's Agent have conducted a multi-party bid process
for the sale of the Property which has culminated in Seller's selection of Buyer
as the party that Seller is willing to sell the Property to in accordance with
the provisions of this Agreement. Commencing prior to the Effective Date and
ending at 5:00 P.M. Pacific Standard Time on November 7, 1996 (the "Due
Diligence Date"), Buyer shall have the opportunity to conduct all due diligence
with regard to the Property as Buyer deems necessary or appropriate in Buyer's
sole and absolute discretion (collectively, the "Due Diligence Investigations").
Buyer shall have the right to terminate this Agreement and receive a return of
the Initial Deposit described in Section 2(a) below if Buyer is dissatisfied
with the Due Diligence Investigations in Buyer's sole discretion by delivering
notice thereof to Seller and Escrow Holder on or before the Due Diligence Date.
Any change in circumstances following the Effective Date will not result in any
adjustment to the Purchase Price, except as expressly provided in this
Agreement.

         NOW, THEREFORE, in consideration of these covenants contained herein
and other good and valuable consideration, the receipt and sufficiency of which
are hereby acknowledged, Buyer and Seller hereby agree as follows, and hereby
instruct Escrow Holder as follows:

         1. Purchase and Sale. Seller agrees to sell to Buyer, and Buyer agrees
to purchase from Seller, the Property upon the terms and conditions set forth in
this Agreement, including, without limitation, the foregoing Recitals.

         2. Purchase Price. The purchase price ("Purchase Price") for the
Property shall be One Hundred Thirty-Three Million Dollars ($133,000,000). The
Purchase Price shall be payable as follows:

                  (a) Initial Deposit. Buyer and Seller hereby irrevocably
         instruct Commerce Escrow Company ("Escrow Holder") to transfer from
         Escrow No. 96-24964-MM, into the escrow described at the top of page 1
         hereof the amount of Two Million Dollars ($2,000,000) (the "Initial
         Deposit") which Buyer delivered to Escrow Holder prior to the Effective
         Date. The Initial Deposit shall be held by Escrow Holder while this
         Agreement is in effect in an interest bearing money market account,
         with all interest accruing thereon being for the benefit of Buyer. All
         interest accrued on the Initial Deposit shall be added to and be deemed
         a part




         of the sum comprising the Initial Deposit. If Buyer elects to terminate
         this Agreement by giving written notice thereof to Seller and Escrow
         Holder on or before the Due Diligence Date, Escrow Holder shall return
         the Initial Deposit to Buyer in accordance with Buyer's instructions
         within two (2) business days following Buyer's delivery of a
         certificate to Seller and Escrow Holder representing that Buyer has
         delivered to Seller, at no charge, copies of all surveys, engineering
         studies, soils reports, environmental reports, and similar studies and
         reports prepared by or for Buyer that pertain to the Property.

                  (b) Second Deposit. If Buyer has not timely terminated this
         Agreement by giving written notice thereof to Seller and Escrow Holder
         on or before the Due Diligence Date, then Buyer hereby covenants to
         deliver to Escrow Holder the sum of Five Million Dollars ($5,000,000)
         (the "Second Deposit"). The Second Deposit shall be delivered by a
         confirmed wire transfer of funds not later than one (1) business day
         after the Due Diligence Date. The Second Deposit shall be added to the
         Initial Deposit and shall continue to be invested in an interest
         bearing money market account, with all interest accruing thereon being
         for the benefit of Buyer. The Initial Deposit, the Second Deposit, and
         all interest accrued thereon, are sometimes hereafter collectively
         referred to as the "Deposit".

                  (c) Treatment of Deposit. If the Second Deposit is not timely
         delivered as required herein, Escrow Holder shall deliver the Initial
         Deposit to Seller, whereupon this Agreement shall terminate. If the
         Second Deposit is timely delivered, thereafter, the Deposit shall
         either be (i) applied and credited toward payment of the Purchase
         Price at the Close of Escrow, or (ii) retained by Seller as liquidated
         damages pursuant to Section 17(b) below, or (iii) returned to Buyer if
         the Close of Escrow does not occur, this Agreement is terminated, and
         the provisions of Sections 4(c), 14, or 17(a) apply.

                  (d) Cash Balance. Not later than 12:00 Noon one (1) business
         day prior to the "Closing Date" (as defined in Section 3(b) below),
         Buyer shall deposit with Escrow Holder cash by means of a confirmed
         wire transfer through the Federal Reserve System in the amount of the
         balance of the Purchase Price, plus Buyer's share of expenses and
         prorations as described in this Agreement.

         3.       Escrow.

                  (a) Opening of Escrow. Buyer and Seller shall promptly deliver
         a fully executed copy of this Agreement to Escrow Holder at the address
         shown on Page 1 following the Effective Date, it being understood and
         agreed that Buyer shall have no obligations hereunder unless and until
         Buyer and Seller execute this Agreement and a fully executed copy of
         this Agreement is delivered to Escrow Holder. Seller hereby authorizes
         Seller's Agent to execute and deliver to Escrow Holder any additional
         or supplementary instructions (which if they are binding upon Buyer
         must have first been reasonably approved by Buyer) as may be




         necessary or convenient to implement the terms of this Agreement and
         close the transactions contemplated hereby, provided such instructions
         are consistent with and merely supplement this Agreement and shall not
         in any way modify, amend or supersede this Agreement. Such
         supplementary instructions, together with the escrow instructions set
         forth in this Agreement, as they may be amended from time to time by
         the parties, shall collectively be referred to as the "Escrow
         Instructions." The Escrow Instructions may be amended and supplemented
         by such standard terms and provisions as the Escrow Holder may request
         the parties hereto to execute; provided, however, that the parties
         hereto and Escrow Holder acknowledge and agree that in the event of a
         conflict between any provision of such standard terms and provisions
         supplied by the Escrow Holder and the Escrow Instructions, the Escrow
         Instructions shall prevail.

                  (b) Close of Escrow. For purposes of this Agreement, the
         "Close of Escrow" shall mean the date on which the "Deed" (as defined
         in Section 5(a)(i) below) is recorded in the Official Records of Los
         Angeles County. The Close of Escrow shall occur on November 21, 1996
         (the "Closing Date"). Buyer acknowledges that there shall be no
         extensions of the Closing Date, and agrees that Buyer's failure to
         perform its obligations hereunder, including without limitation the
         timely delivery of the balance of the Purchase Price, shall constitute
         a material and non-curable default under this Agreement.

         4.       Conditions to the Close of Escrow.

                  (a) Matters Expressly Waived by Buyer. Buyer and Seller
         expressly acknowledge and agree that if Buyer has not terminated this
         Agreement by giving written notice thereof to Seller and Escrow Holder
         on or before the Due Diligence Date, Buyer's obligations under this
         Agreement will not be further conditioned upon the matters described in
         this Section 4(a):

                          (i) Due Diligence. Prior to the Due Diligence Date,
                  Buyer shall have the opportunity to conduct and review the
                  results of all inspections, investigations, tests (including
                  environmental testing) and studies which Buyer elects to make
                  or obtain in connection with its proposed purchase and
                  operation of the Property. In addition, Seller has made and
                  shall continue to make available to Buyer for review a
                  document referred to as the Confidential Memorandum, copies of
                  the Leases, copies of the Intangible Personal Property, copies
                  of any notice alleging uncured violations of "Governmental
                  Regulations" (as defined in Section 10(a)(ii) below), copies
                  of documents relating to pending litigation or written
                  threats of litigation, reports, studies, operating expense
                  information, tenant correspondence, and all similar data and
                  documents which Seller's Agent believes a prudent
                  institutional purchaser of institutional real estate in Los
                  Angeles, California, would reasonably deem relevant, to the
                  extent same are within the possession of Seller or Seller's
                  Agent, excluding




                  "Proprietary Documents" (collectively, the "Due Diligence
                  Documents"). The Due Diligence Documents are described on
                  Exhibit "E" attached hereto. For purposes of this Agreement,
                  "Proprietary Documents" means documents subject to the
                  attorney-client privilege or attorney work product privilege,
                  appraisals, contracts and communications between Seller and
                  Seller's Agent, financial feasibility analyses, business
                  plans, third-party offers to purchase the Property, and
                  similar proprietary financial data and documents, all of which
                  Buyer acknowledges Seller had and has no obligation to
                  disclose or deliver to Buyer. Buyer hereby acknowledges that
                  except as described herein, neither Seller nor Seller's Agent
                  has made nor will make any representation or warranty
                  regarding the accuracy or completeness of the Due Diligence
                  Documents or the sources thereof. Neither Seller nor Seller's
                  Agent has undertaken any independent investigation as to the
                  accuracy or completeness of the Due Diligence Documents, and
                  Buyer has been provided with access to the Due Diligence
                  Documents solely as an accommodation to Buyer. A decision by
                  Buyer to proceed with its purchase hereunder after the Due
                  Diligence Date shall be an acknowledgment by Buyer that Buyer
                  has had the opportunity to review, and has independently and
                  on its own behalf reviewed the accuracy and completeness of
                  the Due Diligence Documents through all independent
                  investigations which Buyer has deemed necessary or desirable.
                  All information actually discovered by Buyer in reviewing the
                  Due Diligence Documents and conducting its own investigations
                  and studies shall be imputed to Buyer, and any express
                  representations or warranties of Seller made in this Agreement
                  shall be deemed correspondingly modified or qualified to
                  reflect such information discovered by Buyer. Buyer further
                  acknowledges and agrees that Seller has no obligation to
                  correct or cure any defects or deficiencies disclosed by the
                  Due Diligence Investigations, and that the Purchase Price
                  adequately reflects Buyer's determination, made in Buyer's
                  sole and absolute discretion, as to the net economic detriment
                  which will be incurred by Buyer in purchasing the Property
                  subject to all of such defects and deficiencies While Buyer
                  shall have the right to continue its Due Diligence
                  Investigations pursuant to the provisions of Section 13(a)
                  below while this Agreement remains in effect, Buyer
                  acknowledges and agrees that no information discovered after
                  the Due Diligence Date, nor any change in circumstances not
                  caused by Seller in breach of this Agreement following the Due
                  Diligence Date (subject to Section 14 below), will relieve
                  Buyer of its obligations to purchase the Property in
                  accordance with the terms hereof.

                           (ii) Tenant Estoppel Certificates. Prior to the
                  Effective Date, Seller's Agent has exercised commercially
                  reasonable efforts to obtain the execution by each tenant
                  under the Leases of tenant estoppel certificates substantially
                  in the form attached to each Lease, which tenant estoppel



                  certificates are substantially in the form of Exhibit "F-I"
                  attached hereto ("Estoppel Certificates"). Attached hereto as
                  Exhibit "F-2" is a schedule of all Estoppel Certificates which
                  were executed prior to the Effective Date and which have been
                  delivered to Buyer for Buyer's review and which cover at least
                  eighty percent (80%) of the net rentable area of the
                  Improvements demised by Leases as of the Effective Date.
                  Seller shall cause Seller's Agent to continue to use
                  commercially reasonable efforts to obtain executed Estoppel
                  Certificates from all tenants under Leases not shown on
                  Exhibit "F-2" , and to deliver copies of such executed
                  Estoppel Certificates to Buyer promptly after receipt thereof.
                  Further, to the extent Buyer determines it necessary to
                  satisfy its line of credit lender, Seller agrees to cause
                  Seller's Agent to use commercially reasonable efforts to
                  obtain updates to the Estoppel Certificates listed on Exhibit
                  "F-2" to a date more current to Close of Escrow. Buyer
                  acknowledges and agrees that delivery of any executed Estoppel
                  Certificates other than those listed on Exhibit "F-2", or
                  delivery of executed Estoppel Certificates other than those
                  listed on Exhibit "F-2" which contain information not 
                  otherwise disclosed by the Due Diligence Investigations, or 
                  delivery of such updates, shall not be a condition to Buyer's
                  obligations hereunder nor relieve Buyer of any of its 
                  obligations hereunder.

                  (b) Conditions Precedent to Buyer's Obligations. The Close of
         Escrow and Buyer's obligations with respect to the transactions
         contemplated by this Agreement are subject to the satisfaction or
         waiver of the following conditions, and the obligations of the parties
         with respect to such conditions are as follows:

                           (i) Title Insurance. As of the Close of Escrow,
                  Chicago Title Insurance Company ("Title Company") shall have
                  committed to issue a standard coverage owner's policy of title
                  insurance showing title to the Real Property vested in Buyer
                  subject only to the "Approved Title Conditions," with a
                  liability amount equal to the Purchase Price, together with
                  reasonable and customary endorsements thereto to the extent
                  specified by Buyer in writing prior to the Due Diligence Date
                  (the "Title Policy"). For purposes of this Agreement,
                  "Approved Title Conditions" means (to the extent Buyer
                  approves of the same in the exercise of its due diligence
                  review rights hereunder): (A) the permitted title exceptions
                  shown on Exhibit "G" attached hereto; (B) liens for taxes,
                  assessments and other charges of governmental or
                  quasi-governmental authorities which are not yet delinquent;
                  (C) zoning, building, access, environmental, and other similar
                  restrictions imposed bylaws, ordinances, rules, requirements,
                  resolutions, policy statements and regulations of governmental
                  and quasi-governmental authorities claiming jurisdiction over
                  the Property, (D) the fights and obligations of parties under
                  the Leases and other parties in possess on; (E) all matters
                  which would be disclosed by an inspection of the Property or a
                  survey of the Real Property; and (F) any other matters



                  heretofore or hereafter existing, whether or not of record or
                  discoverable by inspection, which have been approved, accepted
                  or waived by Buyer pursuant to the terms of this Agreement.
                  Buyer shall have the right to obtain an ALTA extended coverage
                  form of Owner's policy of title insurance, provided that
                  Seller is not required to incur any expense or liability in
                  connection therewith, including but not limited to the
                  execution of affidavits or indemnities in favor of Title
                  Company, other than customary parties-in-possession,
                  mechanics' lien and comprehensive endorsement affidavit; as
                  may be requested by Title Company. If Buyer elects to obtain
                  an ALTA extended coverage form of title insurance policy, or
                  elects to obtain any endorsements (other than as described in
                  the first sentence of this subsection), requests reinsurance
                  or coinsurance, or otherwise elects to obtain any different or
                  additional title insurance coverage in excess of that provided
                  by the Title Policy, obtaining same shall not be a condition
                  to Close of Escrow.

                           (ii) Representations, Warranties and Covenants of
                  Seller. Seller shall have duly performed in all material
                  respects all material covenants to be performed by Seller
                  hereunder (including delivering the documents described in
                  Section 5(a) executed by Seller), and Seller's representations
                  and warranties set forth in this Agreement shall be true and
                  correct as of the Closing Date in all material respects as
                  described in the Date-Down Certificate (as defined in Section
                  5(a)(vi) below). The consummation of the Close of Escrow shall
                  evidence Buyer's acknowledgment that to the best of Buyer's
                  knowledge, Seller has duly performed in all material respects
                  Seller's material covenants and that to the best of Buyer's
                  knowledge, Seller is not in breach of Seller's representations
                  and warranties.

                  (c) Failure of Conditions Precedent to Buyer Obligations. If
         at any time Buyer becomes aware that any condition precedent to Buyer's
         obligations hereunder (i.e., as described in Sections 4(b)(i) or
         4(b)(ii) above) has failed or is reasonably likely to fail as of the
         Closing Date, Buyer shall use best efforts to promptly notify Seller in
         writing of such failure or the reasonable likelihood of failure of such
         condition precedent. All disapprovals of a condition precedent
         described in Section 4(b) above must be in writing pursuant to the
         notice provisions of Section 15 below, and the consummation of the
         Close of Escrow shall be conclusively deemed the approval, acceptance,
         or waiver by Buyer of the conditions precedent set forth in Section
         4(b) above. If Buyer timely disapproves a condition precedent pursuant
         to Section 4(b) above, this Agreement shall not terminate if Seller
         notifies Buyer in writing within five (5) business days after receipt
         of written notice of such disapproval from Buyer stating that Seller
         has elected, in Seller's sole and absolute discretion, to attempt to
         cure or ameliorate such disapproved condition precedent to Buyer's
         reasonable satisfaction, in which event the Closing Date shall be
         extended for a period not to exceed thirty (30)




         days in order to permit Seller adequate time to attempt such cure or
         amelioration. If Seller is successful in curing or ameliorating such
         disapproved condition precedent, within the time period specified in
         the preceding sentence, the Close of Escrow shall thereupon occur not
         later than five (5) business days thereafter. If Seller does not give
         timely written notice to Buyer electing to cure or to ameliorate such
         disapproved condition precedent, or if Seller gives such notice to
         Buyer but thereafter is unable to effect such cure or amelioration,
         then this Agreement shall thereupon terminate and neither Buyer nor
         Seller shall have any further rights or obligations hereunder except as
         are specifically described in this Agreement as surviving the
         termination of this Agreement. If this Agreement so terminates, then
         Escrow Holder shall, as a covenant which survives the termination of
         this Agreement, return the Deposit to Buyer in accordance with Buyer's
         written instructions within two (2) business days following Buyer's
         delivery of a written certification to Seller and Escrow Holder that
         Buyer has delivered to Seller, at no charge, copies of all surveys,
         engineering studies, soils reports, environmental reports, and similar
         studies and reports prepared by or for Buyer that pertain to the
         Property.

                  (d) Conditions Precedent to Seller's Obligations. The Close of
         Escrow and Seller's obligations with respect to the transactions
         contemplated by this Agreement are subject to the timely satisfaction
         or waiver of the following conditions: Buyer shall have duly performed
         in all material respects each and every covenant of Buyer hereunder,
         and Buyer's representations and warranties set forth in this Agreement
         shall be true and correct as of the Closing Date in all material
         respects. Without limitation on the foregoing , Buyer shall have timely
         delivered the Second Deposit and the balance of the Purchase Price
         pursuant to the provisions of Section 2 above, and shall have timely
         delivered all of the duly executed documents required to be delivered
         by Buyer pursuant to Section 5(b) below. All disapprovals given by
         Seller under this Section 4(d) shall be in writing, and the failure of
         Seller to disapprove any matter requiring its approval under this
         Section 4(d) in a timely manner shall be deemed approval thereof by
         Seller.

         5.       Deliveries to Escrow Holder.

                  (a) Seller's Deliveries. Seller hereby covenants and agrees to
         deliver or cause to be delivered to Escrow Holder at least one business
         day prior to the Closing Date the following instruments and documents,

                                    (iv) Proration Schedule. Three (3) duly

        6. Deliveries Upon Close of Escrow. Upon the Close of Escrow, the
following items shall be delivered:

                  (a) Documents. Seller shall deliver to Buyer outside of Escrow

         Policy to Buyer.

         7. Costs and Expenses. Seller shall pay one-half (l/2) of the escrow
fee charged by Escrow Holder, and in addition Seller shall pay outside of escrow
all legal and professional fees and costs of attorneys and other consultants and
agents retained by Seller, including but not limited to any fees payable to
Seller's Agent. Except as described in the preceding sentence, Buyer shall be
responsible for paying all other costs and expenses incurred in connection with
the Due Diligence Investigations and consummating the Close of Escrow. Without
limiting the generality of the preceding sentence, Buyer shall pay through
Escrow, pursuant to Section 2(d) above, all title premiums for the Title Policy,
any title premiums associated with, extended coverage ALTA liability (if
requested by Buyer) and any title endorsements requested by Buyer, all recording
charges, or one-half (1/2) of the escrow fee of Escrow Holder, all city and
county transfer taxes, and all sales, use, intangibles, privilege or other taxes
or




assessments (other than real property taxes which shall be prorated as described
in Section 8 below), assessed with respect to the Property or resulting from the
consummation of the Close of Escrow. Buyer shall pay outside of escrow all costs
and expenses related to the Due Diligence Investigations, and all legal and
professional fees and costs of attorneys and other consultants and agents
retained by Buyer.

         8.       Prorations.

                  (a) General. Except as specifically described in this Section
         8, rentals, revenues, and other income, if any, from the Property, and
         real property taxes and operating expenses, if any, affecting the
         Property shall be prorated as of midnight on the day preceding the
         Close of Escrow, based upon the tentative proration schedule described
         in Section 8(1), as updated by the parties to the Close of Escrow. For
         purposes of calculating prorations, Buyer shall be deemed to be in
         title to the Property, and therefore entitled to the income and
         responsible for the expenses, for the entire day upon which the Close
         of Escrow occurs.

                  (b) Rentals. Subject to the provisions of Sections 8(c) and
         8(d), rentals shall be prorated as of the Close of Escrow, based upon
         the tentative proration schedule described in Section 8(1), as updated
         by the parties to the Close of Escrow. "Rentals" as used herein
         includes fixed rentals, additional rentals, percentage rentals,
         escalation rentals, retroactive rentals, prepaid rentals, operating
         cost pass-throughs and all other sums and charges payable by tenants
         under the Leases.

                  (c) Delinquent Rentals. Rentals are delinquent when payment
         thereof is more than forty-five (45) days delinquent as of the Close of
         Escrow. Rentals which have not been paid when due but which are not yet
         more than forty-five (45) days delinquent as of the Close of Escrow are
         not deemed delinquent and shall be prorated pursuant to Section 8(b)
         above. All rights to delinquent rentals shall be conveyed by Seller to
         Buyer pursuant to the General Assignment. Any delinquent rentals which
         are collected by Buyer following the Close of Escrow (even though same
         are attributable to a period prior to Close of Escrow) shall become the
         sole property of Buyer, and any such delinquent rentals which are
         received by Seller following the Close of Escrow shall, as a covenant
         which survives the Close of Escrow, be delivered by Seller to Buyer
         promptly following receipt thereof. In consideration for the right to
         collect and retain such delinquent rentals, Buyer shall pay to Seller
         through escrow upon the Close of Escrow an amount in addition to the
         Purchase Price calculated as described in this section. Seller shall be
         paid an amount equal to fifty percent (50%) (if all delinquent rentals
         which are more than forty-five (45) and less than ninety-one (91) days
         overdue, Seller shall receive no credit for all delinquent rentals
         which are more than ninety (90) days overdue as of the Close of Escrow.



                  (d) Additional Rentals. Operating cost pass-throughs,
         percentage rentals, additional rentals and other retroactive rental
         escalations, sums or charges payable by tenants under the Leases which
         accrue as of the Close of Escrow but are not then due and payable shall
         be prorated as of the Close of Escrow based upon the projected
         reconciliations as of December 31, 1996 as described on Exhibit "N"
         attached hereto. Said projected reconciliations are based upon the
         actual expenses accrued through September 30, 1996 (as shown on Exhibit
         "N") and projected expenses for the final quarter of 1996. There shall
         be no adjustment following the Close of Escrow if actual expenses for
         1996 (and correspondingly, the amounts owed to or owed by tenants under
         the Leases) are more or less than the projected reconciliations shown
         on Exhibit "N".

                   (e) Prepaid Rentals. Rentals received by Seller attributable
         to periods after the Close of Escrow shall be credited to Buyer and
         debited to Seller at the Close of Escrow.

                  (f) Taxes and Assessments. All non-delinquent real estate
         taxes and current installments of assessments affecting the Property
         which are payable by Seller shall be prorated as of the Close of Escrow
         based on the actual 1996-97 tax bill. All delinquent taxes and
         assessments, if any, affecting the Property which are payable by Seller
         shall be paid at the Close of Escrow from funds accruing to Seller. Any
         pending or future refunds of real estate taxes and assessments
         attributable to the period prior to the Close of Escrow and rights
         thereto shall be conveyed by Seller to Buyer pursuant to the General
         Assignment. Seller anticipates that a portion of any such property tax
         refunds attributable to fiscal years 1994-95, 1995-96 and 1996-97 must
         be refunded or credited to certain tenants pursuant to the terms of the
         Leases. Buyer shall pay to Seller through escrow upon the Close of
         Escrow an amount in addition to the Purchase Price equal to the sum of
         the projected property tax refunds for fiscal years 1994-95, 1995-96
         and 1996-97, less the amounts to be paid or credited to tenants under
         the Leases, such amount to be mutually agreed upon by Buyer and Seller
         prior to the Due Diligence Date. There shall be no adjustment following
         the Close of Escrow if the amount of property tax refunds actually
         received by Buyer and/or the amounts actually paid or credited to
         tenants are more or less than the amounts projected by Buyer and Seller
         prior to the Due Diligence Date. In consideration for the right to
         receive said property tax refunds, as a covenant which shall survive
         the Close of Escrow, Buyer hereby agrees to indemnify, defend and hold
         "Seller Group" harmless from and against all "Claims" (as those terms
         are defined in Section 10 below) arising from or relating to, directly
         or indirectly, any Claims asserted by tenants under Leases regarding
         such refund of property taxes. If for any reason a refund check is made
         payable to Seller, as a covenant which shall survive the Close of
         Escrow, the amount of such refund shall be paid to Buyer by Seller
         promptly upon receipt following the Close of Escrow.



                  (g) Operating Expenses. All utility, service charges for
         electricity, heat and air conditioning service, other utilities,
         elevator maintenance, common area maintenance, taxes (other than real
         estate taxes and income taxes) such as rental taxes, and other expenses
         affecting the Property which are payable by Seller and any other costs
         incurred in the ordinary course of business or the management and
         operation of the Property shall be prorated on an accrual basis. Seller
         shall pay all such expenses that accrue prior to the Close of Escrow
         and Buyer shall pay all such expenses accruing on the Close of Escrow
         and thereafter. To the extent possible, Seller and Buyer shall obtain
         billings and meter readings as of the Close of Escrow to aid in such
         prorations.

                  (h) Tenant Deposits. Buyer shall be credited and Seller shall
         be debited with an amount equal to all Tenant Deposits which are held
         in the form of cash (and any interest accrued thereon for the benefit
         of a tenant pursuant to Leases) by Seller or Seller's Agent under the
         Leases as of the Close of Escrow. All non-cash Tenant Deposits, such as
         certificates of deposit or letters of credit, shall not be prorated but
         shall be assigned to Buyer to the extent assignable. To the extent such
         non-cash Tenant Deposits are not assignable, as a covenant which shall
         survive the Close of Escrow, Seller shall cooperate with Buyer and the
         applicable tenants in order to release security interests in
         certificates of deposit, return original letters of credit, and similar
         actions to permit Buyer to obtain directly from such tenants new
         security interests in certificates of deposit, replacement letters of
         credit, and the like. A schedule of the Tenant Deposits as of the
         Effective Date is attached hereto as Exhibit "D".

                  (i) Seller Deposits. Seller shall be credited and Buyer shall
         be debited with an amount equal to all refundable deposits, retentions,
         and holdbacks, if any, being held as of the Close of Escrow by any
         governmental entity, any utility company, or other third party as
         described in the Intangible Personal Property, together with all
         interest then accrued thereon for the benefit of Seller. A "Schedule of
         Seller's Deposits" as of the Effective Date is attached hereto as
         Exhibit "0".

                  (j) Leasing Commissions. Seller shall pay in full when due,
         either before or after the Close of Escrow, all leasing commissions
         payable with respect to Leases which were fully executed prior to the
         Effective Date. Notwithstanding the preceding sentence, Buyer shall
         pay, if and when same become due, any leasing commission(s) which may
         become due or payable with respect to an expansion or Effective
         extension of any Lease executed prior to the Date, if such extension or
         expansion becomes effective on or following the Effective Date. If
         Seller pays any leasing commissions prior to the Close of Escrow with
         respect to Leases which were fully executed following the Effective
         Date, Buyer shall reimburse Seller for the aggregate amount of such
         payments through escrow as an addition to the Purchase Price as
         described in Section 2(d) above. All other




         leasing commissions which become due and payable with respect to Leases
         shall be paid when due by Buyer following the Close of Escrow.

                  (k) Capital Expenditures and Tenant Improvement Costs. Seller
         has made provision to pay when due certain capital expenditures and
         tenant improvement costs which are more particularly described in the
         1996 column on Exhibit "P" attached hereto. Prior to the Close of
         Escrow, Seller or Seller's Agent shall provide Buyer with copies of
         canceled checks or other reasonably satisfactory documentation of the
         payment when due of the amounts described in the 1996 column on Exhibit
         "P". Buyer shall be credited and Seller shall be debited with an amount
         equal to the aggregate amount shown in the 1996 column on Exhibit "P"
         which has not been so paid by Seller prior to the Close of Escrow, and
         Seller shall thereupon be relieved of further obligation to make any
         further payments with regard to the matters described on Exhibit "P".
         Any such capital expenditure and tenant improvement costs which have
         not been paid to Seller pursuant to the preceding sentence and which
         are required to be paid to a third party under an executory contract
         shall be paid by Buyer when due, and Seller shall be indemnified in
         connection therewith, pursuant to the terms of the General Assignment.
         Except as specifically described in this Section 8, Seller has no
         obligation to pay any other amounts relating to the Leases (or any
         other Intangible Personal Property) or the Real Property.

                  (l) Method of Proration. Seller shall prepare and deliver to
         Buyer a schedule of tentative prorations on or before the fifth (5th)
         business day prior to the Due Diligence Date with respect to the
         Property. Such prorations, if and to the extent known and agreed upon
         as of the Close of Escrow, shall be paid by Buyer to Seller (if the
         prorations result in a net credit to the Seller) or by Seller to Buyer
         (if the prorations result in a net credit to the Buyer) by increasing
         or reducing the cash to be paid by Buyer at the Close of Escrow. Any
         such prorations not determined or not agreed upon as of the Close of
         Escrow (the "Unresolved Proration Issues") shall be paid by Buyer to
         Seller, or by Seller to Buyer, as the case may be, in cash as soon is
         practicable following the Close of Escrow, but in no event more than
         sixty (60) days following the Close of Escrow, as a covenant which
         survives the Close of Escrow. A copy of the final schedule of
         prorations as agreed upon by Buyer and Seller, which shall also
         identify all Unresolved Proration Issues, shall be delivered to Escrow
         Holder prior to the Close of Escrow.

                  (m) Arbitration of Remaining Prorations. If Buyer and Seller
         are unable to mutually agree upon the final allocation of all
         Unresolved Proration Issues within sixty (60) days following the Close
         of Escrow, then all such remaining Unresolved Proration Issues shall be
         submitted to binding arbitration as described in this section as the
         sole remedy therefor. Buyer and Seller shall jointly select a single
         so-called "Big 6" accounting firm which has not performed substantial
         work for either party in the preceding two (2) years. If Buyer and



         Seller are unable to agree, then all of the "Big 6" accounting firms
         which have not performed substantial work for either party in the
         preceding two (2) years shall be compiled on a single list. Buyer and
         Seller shall each delete a name from said list in turn (with the
         identity of the party making the first deletion determined by a
         coin-flip) until only one name remains, which accounting firm shall be
         the arbitrator for purposes of this subsection. Buyer and Seller shall,
         in a single session, each present such oral and written documentation
         to support such party's position as the accounting firm deems relevant
         to the proration issues in dispute. As soon as reasonably possible
         thereafter, the accounting firm shall render a decision based upon the
         evidence submitted and the provisions of this Agreement. Such decision
         shall be final and non-appealable. The aggregate net amount due as
         determined, by the accounting firm shall be paid by Buyer to Seller, or
         Seller to Buyer, as the case may be, within five (5) days following
         such determination. All fees, costs and expenses of said accounting
         firm shall be paid by the party which owed the net amount to the other
         party hereto as described in the preceding sentence.

         9. Disbursements and Other Actions by Escrow Holder. At the Closing
Date, Escrow Holder shall promptly undertake all of the following in the manner
hereinbelow indicated:

                  (a) Funds. Disburse all funds deposited with Escrow Holder by
         Buyer in payment of the Purchase Price as follows:

                  Seller pursuant to Section 7.

                           (ii) If, as the result of the net prorations and
                  credits pursuant to Section 8, amounts are to be charged to
                  the account of Seller, deduct the total amount of such
                  charges.

                           (iii) Disburse the Purchase Price, less the Deposit
                  and the amounts described in subclauses (i) and (ii) above, to
                  Seller promptly upon the Close of Escrow in accordance with
                  Seller's wire transfer instructions.

                           (iv) Disburse any remaining balance in accordance
                  with Buyer's instructions.

                  (b) Recording. Cause the Deed (with documentary transfer tax
         information to be affixed after recording), and any other documents
         which the parties hereto may mutually direct to be recorded in the
         Official Records of Los Angeles County and obtain conformed copies
         thereof for distribution to Buyer and Seller.



                  (c) Title Policy. Direct the Title Company to issue the Title
         Policy to Buyer.

                  (d) Disbursement of Documents to Buyer. Disburse to Buyer
         fully executed originals of the Bill of Sale, the General Assignment,
         the Date-Down Certificate, and any other documents (or copies thereof)
         deposited into Escrow by Seller pursuant hereto.

                  (e) Disbursement of Documents to Seller. Disburse to Seller
         fully executed originals of the Bill of Sale, the General Assignment,
         and any other documents (or copies thereof) deposited into Escrow by
         Buyer pursuant hereto.

                  (f) Tenant Notice Letters. Deliver the Tenant Notice Letters
         to the addressees thereof.

                  the Property and its vicinity which Buyer believes are
                  necessary to protect its own interest in, and its contemplated
                  use of the Property

                                                 -------------------

                  representations and warranties of Seller contained in this
                  Agreement, neither Seller, nor Seller's Agent, nor any person

                           (iii) No Implied Warranties. SELLER HEREBY DISCLAIMS

                           (iv) Information Supplied by Seller. Buyer
                  specifically acknowledges and agrees that, except as expressly
                  contained herein, the Seller Group has made, is making, and
                  shall make no representation or warranty of any nature
                  concerning the accuracy or completeness of the Due Diligence
                  Documents. As to certain of the Due Diligence Documents, Buyer
                  specifically acknowledges that they have been prepared by
                  third parties with whom Buyer has no privity and Buyer
                  acknowledges and agrees that no warranty or representation,
                  express or implied, has been made, nor shall any be deemed to
                  have been made, to Buyer with respect thereto, either by the
                  Seller Group or by any third parties that prepared the same.
                  Buyer waives any claim of any nature against anyone should any
                  information, conclusion, projection, or other statement of any
                  nature contained in any of such materials prove not to be true
                  or accurate for any reason.

                           (v) Negotiated Purchase Price. Subject to completion
                  of the Due Diligence Investigations, Buyer represent; and
                  warrants to Seller that Buyer is specifically familiar with
                  the Property and that Buyer has inspected and examined, or
                  will inspect and examine, all aspects of the Property and its
                  current condition that Buyer believes to be relevant to its
                  decision to purchase the Property. Buyer further acknowledges
                  and agrees that the Purchase Price negotiated by Seller and
                  Buyer reflects the known and unknown risks and liabilities
                  assumed by Buyer under the Agreement, Seller's unwillingness
                  to conduct any investigation or due diligence with respect to
                  the Property on behalf of Buyer, and Seller's desire to
                  receive an absolutely net, fixed amount as consideration for
                  the sale of the Property regardless of any facts known or
                  discovered before or following the Close of Escrow which might
                  result in a diminution in value of the Property.

                  (b) Release. In consideration of the covenants contained in
         this Agreement, Buyer hereby agrees on behalf of itself and Buyer's
         successors and assigns as follows:

                  Buyer's successors and assigns each hereby forever released
                  and discharge the Seller Group of and from any and all claims,
                  demands, obligations, liabilities, indebtedness, breaches of
                  contract, breaches of duty or any relationship, acts,
                  omissions, misfeasance, malfeasance, cause or causes of
                  action, debts, sums of money, accounts, compensations,
                  contracts, controversies, promises, damages, costs, losses and
                  expenses, of every type, kind, nature, description or
                  character which in any way arise out of are connected with or
                  relate to the Property (collectively, "Claims"), including
                  without limitation, any Claims which arise out of or relate to
                  the presence at, under, on or near the Real Property of any
                  Hazardous Materials, irrespective of how, why or by reason of
                  what facts, whether heretofore, now existing or hereafter
                  arising, or which could, might or be claimed to exist, of
                  whatever kind or name, whether known or unknown, suspected or
                  unsuspected, liquidated or unliquidated. Notwithstanding
                  anything to the contrary contained herein, nothing contained
                  herein shall be deemed or construed to be a release or
                  discharge of Seller from any of Seller's obligations under
                  this Agreement.

                           (ii) Buyer hereby agrees, represents and warrants
                  that Buyer realizes and acknowledges that factual matters now
                  unknown to Buyer




                  may have given or may hereafter give rise to Claims which are
                  presently unknown, unanticipated or unsuspected, and Buyer
                  further agrees, represents and warrants that this Agreement
                  has been negotiated and agreed upon in light of that
                  realization and that Buyer nevertheless intends hereby to
                  release and discharge the Seller Group from any such unknown
                  Claims which are in any way related to the Property except as
                  expressly provided to the contrary in this Agreement. In
                  furtherance of this intention, Buyer expressly waives any and
                  all rights conferred upon Buyer or Buyer's successors and
                  assigns by the provisions of California Civil Code Section
                  1542, and expressly consents that this Agreement shall be
                  given full force and effect according to each of its express
                  provisions. Section 1542 provides.- "A GENERAL RELEASE DOES
                  NOT EXTEND TO CLAIMS WHICH A CREDITOR DOES NOT KNOW OR SUSPECT
                  TO EXIST IN HIS FAVOR AT THE TIME OF EXECUTING THE RELEASE
                  WHICH IF KNOWN BY HIM MUST HAVE MATERIALLY AFFECTED HIS
                  SETTLEMENT WITH THE DEBTOR."

                                                  Buyer's Initials

                           (iii) Buyer hereby understands and agrees that
                  Seller's requirement that the preceding provisions be agreed
                  to by Buyer shall not be deemed or construed as an admission
                  of liability by Seller, and Seller hereby expressly denies
                  liability of any nature whatsoever arising from or related to
                  the Property.

                  that Buyer has had advice of counsel of its own choosing in
                  the negotiation of this Agreement, that Buyer has read this
                  Agreement or has had the same read to it by Buyer's counsel,
                  that Buyer has had this Agreement fully explained by such
                  counsel, and that Buyer is fully aware of the contents and
                  legal effect of this Agreement.

         11. Seller's Representations and Warranties. In addition to any express
agreements of Seller contained herein, the following constitute representations
and warranties of Seller:



                  (a) Power. Seller has the legal power, right and authority to
         enter into this Agreement and the instruments referenced herein, and to
         consummate the transactions contemplated hereby.

                  (b) Requisite Action. All requisite action (corporate, trust,
         partnership or otherwise) has been taken by Seller in connection with
         the entering into this Agreement and the instruments referenced herein
         and the consummation of the transactions contemplated herein.

                  (c) Authority. The individuals executing this Agreement and
         the instruments referenced herein on behalf of Seller have the legal
         power, right and actual authority to bind Seller to the terms and
         conditions hereof and thereof.

                  (d) Due Diligence Documents. To Seller's actual knowledge, the
         Due Diligence Documents represent all of the document; and materials
         (other than Proprietary Documents) which as of the Effective Date were
         within the possession of Seller or Seller's Agent which currently
         affect or relate to the Property and which a prudent institutional
         purchaser of institutional real estate in Los Angeles, California would
         reasonably deem relevant in connection with a potential purchase of
         such real estate. As used herein, the phrase "to Seller's actual
         knowledge" means the actual, conscious knowledge of Colin Shepherd and
         Mary McCubbin, following a review of all files maintained by Seller's
         Agent relating to the Property, and the actual, conscious knowledge of
         William A. Roche. Seller represents and warrants that: (i) William A.
         Roche is the President of Seller and the individual within Seller's
         organization with primary responsibility for the Property, (ii) Colin
         Shepherd and Mary McCubbin, both of whom are officers or employees of
         Seller's Agent, are the individuals with primary responsibility for
         managing the business activities and overseeing all employees of
         Seller's Agent with respect to the Property, and (iii) no officer or
         employee of Seller is likely to possess any knowledge with respect to
         the Property which is not also possessed by William A. Roche, Colin
         Shepherd or Mary McCubbin.

                  (e) All notices received by Seller of pending or threatened
         litigation or alleged violations of Government Regulations pertaining
         to the Property and all currently effective Leases, service contracts,
         maintenance agreements, construction contracts, listing agreements and
         similar agreements, if any, relating to the Real Property which are in
         writing and which have been duly executed by Seller or Seller's Agent
         are included in the Due Diligence Documents made available for Buyer's
         review.

Buyer and Seller expressly acknowledge and agree that the representations and
warranties of Seller contained in this Agreement shall survive the Close of
Escrow, but any and all liability of Seller for breach of any such
representation or warranty shall terminate and such representations and
warranties shall thereafter be null and void if Buyer does not deliver a written
claim of breach, specifying such representation or warranty which has




allegedly been breached and the supporting evidence for the alleged breach, on
or prior to the date which is one hundred eighty (180) days following the Close
of Escrow. In the event that such written claim of breach of representation or
warranty is timely delivered, and it is thereafter determined that Seller did in
fact breach such representation or warranty, Seller's liability to pay damages
therefor shall not apply with respect to the first One Hundred Thousand Dollars
($100,000) of such damages in the aggregate, with the intent and effect that
Seller shall only owe damages to Buyer for such breach of such representation or
warranty if Buyer's damages in connection therewith are determined to exceed One
Hundred Thousand Dollars ($100,000) in the aggregate.

         12. Buyer's Representations and Warranties. In addition to any express
agreements of Buyer contained herein, the following constitute representations
and warranties of Buyer which shall survive the Close of Escrow:

                  (a) Power. Buyer has the legal power, right and authority to
         enter into this Agreement and the instruments referenced herein, and to
         consummate the transactions contemplated hereby.

                  (b) Requisite Action. All requisite action (corporate, trust,
         partnership or otherwise) has been taken by Buyer in connection with
         the entering into this Agreement and the instruments referenced herein,
         and the consummation of the transactions contemplated hereby.

                  (c) Authority. The individuals executing this Agreement and
         the instruments referenced herein on behalf of Buyer have the legal
         power, right and actual authority to bind Buyer to the terms and
         conditions hereof and thereof.

                  (d) Principal. Buyer has executed this Agreement as a
         principal on its own behalf and not as an agent of undisclosed third
         parties.

         13.      Covenants of Buyer and Seller.

                  (a) Access by Buyer. On or before the Effective Date, Buyer
         shall execute that certain Access, Insurance and Indemnification
         Agreement in favor of Seller in connection with Buyer's Due Diligence
         Investigations in the form attached hereto as Exhibit "Q". While this
         Agreement remains in effect, Buyer shall continue to be entitled to
         enter upon the Real Property pursuant and subject to the provisions of
         said Access, Insurance and Indemnification Agreement.

                  (b) Confidentiality. Prior to the effective Date, Buyer
         executed that certain Confidentiality Agreement dated June 28, 1996.
         Buyer acknowledges that Buyer continues to be bound by the provisions
         of said Confidentiality Agreement until the Close of Escrow occurs,
         whereupon the Confidentiality Agreement shall thereupon terminate
         except with respect to obligations or liabilities theretofore accrued.
         Notwithstanding anything to the contrary contained in the



         Confidentiality Agreement, Seller acknowledges that Beacon Properties
         Corporation, the general partner of Buyer, is a publicly-owned
         corporation subject to regulation by the Securities and Exchange
         Commission, and that the regulations of the Securities and Exchange
         Commission may require that Buyer disclose the existence of this
         Agreement and the contents of some or all of the documents delivered by
         Seller in connection therewith. Accordingly, Seller expressly consents
         to such disclosure of the terms and conditions of this Agreement and
         the transactions contemplated hereby, provided, however, if such
         disclosure is to be made prior to the Close of Escrow, Buyer shall
         deliver to Seller an opinion of Buyer's counsel that in such counsel's
         reasonable judgment the Securities and Exchange Commission regulations
         require disclosure of the documents and/or information described in
         such opinion of counsel. In addition to the disclosure contemplated by
         the preceding sentence, and without limitation thereof, either party
         may disclose the existence of this Agreement or the contents thereof
         or of any documents to be executed and/or delivered in connection
         herewith to any partners, advisors, underwriters, analysts, employees,
         affiliates, officers, directors, consultants, lenders, accountants or
         legal counsel of any of the foregoing, provided that such party has a
         reasonable need to know the disclosed information and such party is
         advised as to the confidential nature of such information and is
         instructed to maintain such confidentiality. Following the Due
         Diligence Date, either Seller or Buyer may issue a press release with
         respect to this Agreement and the transactions contemplated hereby
         (excluding any reference to the Purchase Price unless such press
         release is issued following the Close of Escrow), subject to the
         approval of the other party hereto, which approval shall not be
         unreasonably withheld or delayed.

                  (c) Publicity. Neither Seller nor Buyer shall make any public
         announcement or press release with respect to the execution of this
         Agreement, or the termination of this Agreement, if such termination
         occurs. Neither Buyer nor Seller shall make any public announcement or
         press release with respect to the occurrence of Close of Escrow without
         first giving the other party hereto prior written notice thereof and
         providing such other party a reasonable opportunity to approve the
         contents of such public announcement or press release.

                  (d) Termination of Seller's Agent. Seller shall take all
         actions necessary or appropriate regarding its contractual arrangements
         with Seller's Agent in order that upon the Close of Escrow, Seller's
         Agent shall have no further rights or obligations with respect to the
         Property and so that Seller's Agent shall have no claim against Buyer,
         and Buyer shall have no claim against Seller's Agent, with respect
         thereto.

                  (e) Continued Operation. While his Agreement is in effect,
         until the Close of Escrow, Seller covenants to own, operate and
         maintain (subject to Section 14) the Property in substantially the same
         manner as presently owned, operated and maintained, and in accordance
         with commercially reasonable




         business practices. While this Agreement is in effect, until the Due
         Diligence Date, Seller agrees not to (i) enter into any new Lease
         (unless such new Lease is executed on Seller's standard form of Lease
         for the Property, with such substantially similar modifications as
         Seller has permitted in other Leases to tenants of similar size and
         credit-worthiness, and contains economic terms consistent with the
         leasing guidelines attached hereto as Exhibit "R", (ii) materially
         amend or terminate any existing Lease (except to extend the term of the
         Lease and/or expand the demised premises on terms consistent with the
         leasing guidelines attached as Exhibit "R"), or (iii) enter into any
         other obligation (other than contracts to perform tenant improvements
         for Leases, and contracts relating to capital expenditures as
         contemplated by Exhibit "P") which shall bind the Property following
         the Close of Escrow and which is not terminable without penalty upon
         not more than thirty (30) days notice, without first obtaining the 
         prior consent of Buyer. Following the Due Diligence Date, while this
         Agreement is in effect, Seller agrees not to: (i) enter into any new
         Lease, (ii) materially amend or terminate any existing Lease, or (iii)
         enter into any other obligation which shall bind the Property following
         the Close of Escrow and which is not terminable without penalty upon
         not more than thirty (30) days notice, without first obtaining the
         prior consent of Buyer. Any consent required from Buyer hereunder shall
         not be unreasonably withheld or delayed  and shall be deemed given if
         not disapproved within five (5) business days following Buyer's receipt
         of request for such approval, provided, however, if Buyer notifies
         Seller in writing within two (2) business days following receipt of
         such request that the information supplied by Seller is insufficient to
         reasonably evaluate such request, then said five (5) business day
         period shall not commence until the requested information has been
         supplied. Seller shall cause Seller's Agent to use commercially
         reasonable efforts to notify Buyer promptly following the execution of
         any document described in the preceding sentences which did not require
         Buyer's prior written consent.

                  (f) Access by Seller. Buyer covenants that from and after the
         Close of Escrow, Buyer shall allow Seller and its representatives,
         attorneys and accountants, upon reasonable prior notice and during
         normal business hours, access to such documents and materials relating
         to the Property as Seller may request for the purpose of examining and
         copying same, and shall otherwise cooperate with Seller, in connection
         with any litigation between Seller and third parties, the preparation
         of any required tax returns, any tax procedure or litigation, any
         obligation or duty hereunder or under the foregoing, or compliance with
         any legal duty or obligation.

                  (g) Audit Rights. To comply with the regulations of the
         Securities and Exchange Commission with respect to the verification of
         historical information, Buyer shall have the right, prior to or
         subsequent to the Close of Escrow, to conduct an audit, at Buyer's sole
         cost and expense, of Seller's books and records for and with respect to
         the Property for the shorter of (i) three (3) years prior to the Close
         of Escrow, or (ii) the period of Seller's ownership thereof Seller
         hereby




         agrees to permit Buyer and Buyer's accountants access to Seller's books
         and records (including those maintained by Seller's Agent) and, at
         Buyer's sole cost and expense, to reasonably cooperate and to cause
         Seller's accountants to cooperate with Buyer to enable such audit to be
         performed. The provisions of this subsection shall survive Close of
         Escrow. Buyer acknowledges and agrees that whether such audit is
         conducted before or following the Close of Escrow, there shall be no
         extension of the Closing Date, no extension of the survival period of
         Seller's representations and warranties contained herein, no adjustment
         to the Purchase Price or any prorations described herein (except to the
         extent Buyer would have such right absent the provisions of this
         Section 13(g)) and Seller shall be at absolutely no cost, expense, or
         liability in connection with any such audit.

         14. Casualty and Condemnation. In the event that all or any portion of
the Property is materially damaged, or in the event that a material portion of
the Property is condemned, while this Agreement is in effect and prior to the
Close of Escrow, Buyer shall have the right to terminate this Agreement by
giving written notice thereof to Seller and Escrow Holder within five (5)
business days after learning of same. For purposes hereof, "material" shall mean
a repair, reconstruction or replacement cost reasonable, estimated to be in
excess of One Million Dollars ($1,000,000). If Buyer elects to terminate this
Agreement pursuant to this Section 14, the Deposit shall be refunded to Buyer
pursuant to Section 4(c) above. In the event the damage or condemnation is not
"material" or if Buyer does not timely elect to terminate this Agreement as
aforesaid, this Agreement shall remain in full force and effect and the parties
shall proceed to the Close of Escrow without reduction in the Purchase Price,
except that Seller shall assign to Buyer any insurance or condemnation proceeds
received or receivable by Seller, if any, as a result of such damage or
condemnation.

         15. Notices. All notices or other communications required or permitted
hereunder shall be in writing, and shall be personally delivered (including by
means of professional messenger service or reputable air express service
utilizing receipts) or sent by telecopy, receipt confirmed, and shall be deemed
received upon the date of receipt thereof if received prior to 5:00 p.m. (of the
recipient's time zone) of the recipient's business day, and if not so received,
shall be deemed received upon the following business day.

Notice of change of address shall be given by written notice in the manner
detailed in this Section 15.

         16. Commissions. If the Close of Escrow occurs, Seller shall pay to
Seller's Agent a fee pursuant to a separate agreement with Seller's Agent. Other
than as specified in the preceding sentence, Seller represents and warrants to
Buyer, and Buyer represents and warrants to Seller, that no other advisor,
broker or finder has been engaged by it, respectively, in connection with any of
the transactions contemplated by this Agreement, or to its knowledge is in any
way connected with any of such transactions. In the event of any such claims for
additional advisor's, brokers' or finders' fees or commissions in connection
with the negotiation, execution or consummation of this Agreement, then as a
covenant which shall survive the termination of this Agreement or the Close of
Escrow, Buyer shall indemnify, save harmless and defend Seller from and against
such claims if they shall be based upon any statement or representation or
agreement by Buyer, and




Seller shall indemnify, save harmless and defend Buyer if such claims shall be
based upon any statement, representation or agreement made by Seller.

        17.       Legal and Equitable Enforcement of this Agreement.

                  (a) Default by Seller. IN THE EVENT THE CLOSE OF ESCROW AND
         THE CONSUMMATION OF THE TRANSACTIONS HEREIN CONTEMPLATED DO NOT OCCUR
         BY REASON OF ANY DEFAULT BY SELLER, BUYER SHALL BE ENTITLED TO EITHER
         (i) TERMINATE THIS AGREEMENT AND THE ESCROW AND RECOVER FROM SELLER ALL
         OF ITS OUT-OF-POCKET EXPENSES INCURRED IN CONNECTION WITH THE
         TRANSACTION, INCLUDING THE DEPOSIT, OR (ii) SEEK THE SPECIFIC
         PERFORMANCE HEREOF.

                  (b) Default by Buyer. IN THE EVENT THE CLOSE OF ESCROW DOES
         NOT OCCUR AS HEREIN PROVIDED BY REASON OF ANY DEFAULT OF BUYER, BUYER
         AND SELLER AGREE THAT IT WOULD BE IMPRACTICAL AND EXTREMELY DIFFICULT
         TO ESTIMATE THE DAMAGES WHICH SELLER MAY SUFFER. THEREFORE BUYER AND
         SELLER DO HEREBY AGREE THAT A REASONABLE ESTIMATE OF THE TOTAL NET
         DETRIMENT THAT SELLER WOULD SUFFER IN THE EVENT THAT BUYER DEFAULTS AND
         FALLS TO COMPLETE THE PURCHASE OF THE PROPERTY IS AND SHALL BE, AS
         SELLER'S SOLE AND EXCLUSIVE REMEDY (WHETHER AT LAW OR IN EQUITY), AN
         AMOUNT EQUAL TO THE DEPOSIT. SAID AMOUNT SHALL BE THE FULL, AGREED AND
         LIQUIDATED DAMAGES FOR A BREACH OF THIS AGREEMENT BY BUYER WHICH
         RESULTS IN THE CLOSE OF ESCROW NOT OCCURRING, ALL OTHER CLAIMS TO
         DAMAGES OR OTHER REMEDIES BEING HEREIN EXPRESSLY WAIVED BY SELLER.
         NOTHING CONTAINED IN THIS SECTION SHALL LIMIT SELLER'S RIGHT TO RECEIVE
         REIMBURSEMENT FOR COSTS AND EXPENSES PURSUANT TO SECTION 19(e) BELOW,
         NOR WAIVE OR AFFECT BUYER'S INDEMNITY OBLIGATIONS AND OBLIGATIONS WHICH
         BY THEIR TERMS SURVIVE THE CLOSE OF ESCROW.

                  (c) Waiver of Right to Record Lis Pendens. AS PARTIAL
         CONSIDERATION FOR SELLER ENTERING INTO THIS AGREEMENT, BUYER EXPRESSLY
         WAIVES ANY RIGHT (AT COMMON LAW OR OTHERWISE) TO RECORD OR FILE A LIS
         PENDENS OR A NOTICE OF PENDENCY OF ACTION OR SIMILAR NOTICE AGAINST ALL
         OR ANY PORTION OF THE PROPERTY IN CONNECTION WITH ANY ALLEGED DEFAULT
         BY SELLER HEREUNDER.

        18.       Assignment, Exchange, and Back-up Offers.

                  (a) Assignment. Prior to the Close of Escrow, Buyer shall not
         assign, transfer or convey its rights and obligations under this
         Agreement or in the Property without the prior written consent of
         Seller, and any purported assignment, transfer or conveyance without
         such consent of Seller shall be null and void. Seller may withhold its
         consent to any proposed assignee of Buyer in Seller's sole and absolute
         discretion. Notwithstanding anything to the contrary contained herein,
         Buyer shall have the right to assign all, but not less than all, of
         Buyer's rights and obligations hereunder to any entity which is
         controlled by, controlling, or under common control with, Buyer without
         obtaining Seller's prior written consent, provided that Seller receives
         at least five (5) business days prior to the Closing Date a copy of the
         Fully executed assignment and assumption documentation between Buyer
         and Buyer's assignee, together with documentation evidencing that such
         assignee is affiliated with Buyer as described in this sentence. Any
         permitted assignee shall succeed to all of Buyer's rights and remedies
         hereunder. Notwithstanding the foregoing, no such permitted assignment
         shall relieve Buyer from its liability under this Agreement.

                  (b) Back-Up Offers. Until the Close of Escrow, Seller shall
         have the right to continue to present the Property for sale and accept
         "back-up" offers contingent upon Buyer's failure to perform under the
         terms of the Agreement. Any such "back-up" offer may permit the
         purchaser thereunder to review the Due Diligence Documents but shall
         prohibit any other due diligence with respect to the Property while
         this Agreement is in effect.

         19.      Miscellaneous.

                  (a) Governing Law. The parties hereto acknowledge that this
         Agreement has been negotiated and entered into in California. The
         parties hereto expressly agree that this Agreement shall be governed
         by, interpreted under, and construed and enforced in accordance with
         the laws of the State of California.

                  (b) Partial Invalidity. If any term or provision or portion
         thereof of this is Agreement or the application thereof to any person
         or circumstance shall, to any extent, be invalid or unenforceable, the
         remainder of this Agreement, or the application of such term or
         provision or portion thereof to persons or circumstances other than
         those as to which it is held invalid or unenforceable, shall not be
         affected thereby, and each such term and provision of this Agreement
         shall be valid and be enforced to the fullest extent permitted by law.

                  (c) Waivers. No waiver of any breach of any covenant or
         provision herein contained shall be deemed a waiver of any preceding or
         succeeding breach thereof, or of any other covenant or provision herein
         contained. No extension of




         time for performance of any obligation or act shall be deemed an
         extension of the time for performance of any other obligation or act.

                  (d) Successors and Assigns. Subject to Section 18(a) above,
         this Agreement shall be binding upon and shall inure to the benefit of
         the permitted successors and assigns of the parties hereto.

                  (e) Professional Fees. In the event of the bringing of any
         action or suit by a party hereto against another party hereunder by
         reason of any breach of any of the covenants, agreements or provisions
         on the part of the other party arising out of this Agreement, then in
         that event the prevailing party shall be entitled to have and recover
         of and from the other party all costs and expenses of the action or
         suit and any appeals therefrom, and enforcement of any judgment in
         connection therewith, including actual attorneys' fees, accounting and
         engineering fees, and any other professional fees resulting therefrom.

                  (f) Entire Agreement. This Agreement (including all Exhibits
         attached hereto) is the final expression of, and contains the entire
         agreement between, the parties with respect to the subject matter
         hereof and supersedes all prior understandings with respect thereto.
         This Agreement may not be modified, changed, supplemented or
         terminated, nor may any obligations hereunder be waived, except by
         written instrument signed by the party to be charged or by its agent
         duly authorized in writing or as otherwise expressly permitted herein.
         This Agreement may be executed in one or more counterparts, each of
         which shall be an original, and all of which together shall constitute
         a single instrument. The parties do not intend to confer any benefit
         hereunder on any person, firm or corporation other than the parties
         hereto.

                  (g) Time of Essence. Seller and Buyer hereby acknowledge and
         agree that time is strictly of the essence with respect to each and
         every term, condition, obligation and provision hereof and that failure
         to timely perform any of the terms, conditions, obligations or
         provisions hereof by either party shall constitute a material breach of
         and a non-curable (but waivable) default under this Agreement by the
         party so failing to perform.

                  (h) Construction. Headings at the beginning of each paragraph
         and subparagraph are solely for the convenience of the parties and are
         not a part of the Agreement. Whenever required by the context of this
         Agreement, the singular shall include the plural and the masculine
         shall include the feminine and vice versa. This Agreement shall not be
         construed as if it had been prepared by one of the parties, but rather
         as if both parties had prepared the same. Unless otherwise indicated,
         all references to sections are to this Agreement. All exhibits referred
         to in this Agreement are attached and incorporated by this reference.
         In the event the date on which Buyer or Seller is required to take any
         action under the terms of this




         Agreement is not a business day, the action shall be taken on the next
         succeeding business day.

         IN WITNESS WHEREOF, the parties hereto have executed this Agreement as
