           A.    Escrow Deposit.  Within two (2) business days of the
Effective Date, Buyer shall deliver $250,000 (together with all interest
thereon, the _xe "\"Escrow Deposit\":"_"Initial Escrow Deposit") to Chicago
Title Insurance Company, 110 West Taylor Street, San Jose, California 95110
Attention:  Linda Tugade (which company or such other national title
insurance company selected by Buyer within two (2) business days of the
Effective Date, and reasonably approved by Seller, in its capacity as
escrow holder hereunder, is called _xe "\"Escrow Holder\":"_"Escrow
Holder").  In addition, if Buyer shall deliver the "Approval Notice" prior
to the expiration of the "Due Diligence Period", as provided (and defined)
in paragraph 4B hereof, Buyer shall concurrently therewith deliver Buyer's
check in the amount of $500,000 (the "Additional Escrow Deposit") to Escrow
Holder.  The Additional Escrow Deposit shall be in the form of Buyer's
check which shall be held uncashed by the Escrow Holder until such time as
the Closing occurs or, pursuant to the terms hereof, Seller notifies Escrow
Holder and Buyer that Seller believes in its good faith discretion that it
is entitled to the Escrow Deposit.  The Initial Escrow Deposit to be made
hereunder shall be made by a bank or cashier's check drawn on a major
national money center banking institution (or by other delivery of good
funds reasonably acceptable to Seller), and the amounts so deposited shall
be held by Escrow Holder as a deposit against the Purchase Price in
accordance with the terms and provisions of this Agreement.  The parties
hereto hereby acknowledge that the closing of the transactions hereunder
(the "Closing") will occur not later than December 30, 1997, and that the
parties will reasonably cooperate to most effectively and efficiently cause
the delivery of all sums hereunder so as to avoid multiple wires or
deliveries of funds hereunder.  As used herein, the term "Escrow Deposit"
means the Initial Escrow Deposit and, from and after the delivery of good
funds, the Additional Escrow Deposit, together with all interest earned on
such deposits while the same are held in escrow hereunder.  At all times in
which the Escrow Deposit is being held by the Escrow Holder, the Escrow
Deposit shall be invested by Escrow Holder in the following investments
(_xe "\"Approved Investments\":"_"Approved Investments"):  (i) United
States Treasury obligations, (ii) United States Treasury-backed repurchase
agreements issued by a major national money center banking institution
reasonably acceptable to Seller, or (iii) such other manner as may be
reasonably agreed to by Seller and Buyer.  The Escrow Deposit shall be
disposed of by Escrow Holder only as provided in this Agreement.
Notwithstanding anything to the contrary contained herein the Escrow Holder
shall not be obligated or entitled to cash the Buyer's check for the
Additional Escrow Deposit until such time as the Closing occurs or Seller
notifies Escrow Holder and Buyer that Seller believes in its good faith
discretion that it is entitled to received the Escrow Deposit pursuant to
the terms hereof.  In the event that pursuant to the terms hereof Buyer is
entitled to the return of the Escrow Deposit, Buyer's check for the
Additional Escrow Deposit shall be returned to Buyer uncashed.



<PAGE>


           B.    Closing Payment.  The balance of the Purchase Price
(i.e., the Purchase Price less the sum of the Escrow Deposit available as
of the date thereof in good funds, as such amounts shall be adjusted by the
prorations and credits specified herein) shall be paid by wire transfer
through "Escrow" as hereinafter provided of immediately available federal
funds on the Closing Date (the amount to be paid under this subparagraph B
being herein called the "Closing Payment").

     4.    Conditions Precedent.

           A.    Title Matters.

Title Report.

     (a)   Buyer has received a copy of a preliminary title report (_xe
"\"Preliminary Title Report\":"_"Preliminary Title Report") covering the
Property from Chicago Title Insurance Company (which company, or such other
national title insurance company selected by Buyer within two (2) business
days of the Effective Date and reasonably approved by Seller, in its
capacity as title insurer hereunder, is herein called the _xe "\"Title
Company\":"_"Title Company").  In addition, Seller has ordered (and will
use good faith efforts to cause the delivery to Buyer on or before December
15, 1997) an update of that certain survey of the Property prepared by
Mountain Pacific Surveys, which survey shall be certified in customary form
to Buyer and Title Company (_xe "\"Survey\":"_"Survey"). If Buyer shall
fail to deliver a "Title Objection Notice" (as hereinafter defined) setting
forth those title and survey matters to which Buyer objects in its sole and
absolute discretion on or before the date which is five (5) business days
prior to the end of the "Due Diligence Period", as hereinafter defined (the
"Title Review Period"), Buyer shall be deemed to have disapproved the
exceptions to title shown on the Preliminary Title Report and the matters
disclosed on any survey(s) obtained or delivered hereunder.

     (b)   Additional Title Matters.  Approval by Buyer in its sole and
absolute discretion of any additional exceptions to title matters first
disclosed to or discovered by Buyer after the delivery of the Title
Objection Notice shall be a condition precedent to Buyer's obligation to
purchase the Property.  Unless Buyer gives written notice that it approves
any such additional exceptions to title or survey matters, stating the
exceptions so approved, on or before the sooner to occur of three (3)
business days after receipt of written notice thereof and the Closing Date,
Buyer shall be deemed to have disapproved said additional title exception
matters.

     (c)   Title Objections.  If Buyer shall not approve any title or
survey matters which Buyer is permitted to disapprove hereunder, Buyer
shall have the right to give written notice thereof ("Title Objection
Notice") to Seller within the time periods provided for in
Paragraphs 4A(1)(a) or (b), as applicable.  Upon receipt by Seller of a
Title Objection Notice given in a timely manner (or a deemed title
disapproval under Paragraphs 4A(1)(a) or (b) above), then Seller shall have
until the sooner to occur of (1) three (3) business days from receipt of
such Title Objection Notice (or from the date of Buyer's deemed disapproval
as aforesaid) and (2) the Closing Date, within which to notify Buyer as to
each properly disapproved matter either that (i) Seller elects not to cause
such disapproved matter to be removed as of the Closing Date (or otherwise
take any action with respect thereto), or (ii) Seller intends to either (a)
use commercially reasonable efforts to cause such disapproved matter to be
removed on the Closing Date, or (b) obtain a title endorsement (if
available) reasonably acceptable to Buyer insuring over such disapproved
matter; provided, however, Seller shall have no liability if for any
reason, after electing under (ii) above, such additional disapproved
matters are not removed or insured over in a form reasonably acceptable to


<PAGE>


Buyer as of the Closing Date.  Failure to deliver any written notification
by Seller of its election within such period shall be deemed to be an
election not to cause any such additional disapproved matters to be
removed.  If Seller elects not to cause any or all such additional
disapproved matters to be removed or insured over as aforesaid, Buyer shall
have until the sooner to occur of (1) three (3) business days from receipt
of written notice thereof (or from the date of Seller's deemed election as
aforesaid) and (2) the Closing Date, within which to notify Seller in
writing either that (x) Buyer revokes its disapproval and will proceed with
the purchase of the Property without any reduction in the Purchase Price
and will take subject to such matters, or (y) Buyer terminates this
Agreement (and thereupon the Escrow Deposit shall be delivered to Buyer).
Failure to deliver any written notification by Buyer of its election within
such period shall be deemed to be an election to terminate this Agreement.

     (d)   Permitted Exceptions.  All matters set forth on the Preliminary
Title Report which are approved by Buyer pursuant to the terms are herein
called the "Permitted Exceptions".  The term "Permitted Exceptions" shall
additionally include (i) any title matters objected to by Buyer, which
objections are subsequently waived in writing by Buyer, and (ii) any title
matters objected to by Buyer, which objections are removed or which are
otherwise satisfactorily cured as determined by Buyer in its sole and
absolute discretion.  Buyer shall have the option to waive the condition
precedent set forth in this paragraph 4A(1) by written notice to Seller.
In the event of such waiver, such condition shall be deemed satisfied.

           (2)   Exceptions to Title.  Buyer shall be obligated to accept
title to the Property, subject to the following exceptions to title:

           (a)   Real estate taxes and assessments not yet due and
payable;

           (b)   The standard printed exceptions of the standard form ALTA
owner's policy of title insurance with so-called "extended coverage" issued
by Title Company in the State of California; and

           (c)   The Permitted Exceptions.
Conclusive evidence of the availability of such title shall be the
irrevocable commitment of Title Company to issue to Buyer on the Closing
Date a standard ALTA owner's policy of title insurance with so-called
"extended coverage" ("Owner's Policy"), in the face amount of the Purchase
Price, which policy shall (i) show title to the Property to be vested of
record in Buyer, (ii) show the Permitted Exceptions to be the only
exceptions to title, and (iii) contain such endorsements or additional
coverage as Buyer may have requested and Title Company shall have committed
to issue in writing during the Due Diligence Period to issue.

           B.    Due Diligence Reviews.  Buyer shall have until 5:00 p.m.
(Pacific time) on December 26, 1997 (the _xe "\"Due Diligence
Period\":"_"Due Diligence Period"), within which to perform and complete
all of Buyer's due diligence examinations, reviews and inspections of all
matters pertaining to the purchase of the Property, including all leases,
service contracts, survey and title matters, and all physical,
environmental, structural, zoning, land use and compliance matters and
conditions respecting the Property and any other matters Buyer deems
relevant in its sole and absolute discretion.  During the Due Diligence
Period, Seller shall provide Buyer with reasonable access to the Property
upon reasonable advance notice.  Prior to the Effective Date, Seller shall
have delivered to Buyer or made available to Buyer at the office of the
Property in San Jose, California all leases, service contracts, third party
reports or studies, correspondence with tenants or service providers and
all other material documents respecting the Property (to the extent the
same are known to Seller and are in Seller's possession or reasonably
available to Seller).  Buyer shall at all times conduct its due diligence
review, inspections and examinations in a manner so as to not cause
material damage, loss, cost or expense to Seller or the Property and so as
to not materially interfere with or disturb any tenant at the Property, and


<PAGE>


Buyer will indemnify, defend, and hold Seller and the Property harmless
from and against any such damage, loss, cost or expense (the foregoing
obligation surviving any termination of this Agreement); provided, however,
nothing contained in the foregoing shall impose any liability upon Buyer
for the mere discovery by Buyer of any pre-existing conditions.  Without
limitation on the foregoing, in no event shall Buyer (a) make any intrusive
physical testing (environmental, structural or otherwise) at the Property
(such as soil borings, water samplings or the like) without Seller's
express written consent.  Buyer will coordinate any tenant contact with
Seller and comply with any reasonable requirements of Seller in connection
therewith (including scheduling tenant contacts toward the end of the Due
Diligence Period).  Seller shall have the right, at its option, to cause a
representative of Seller to be present at all inspections, reviews and
examinations conducted hereunder.  Buyer shall promptly deliver to Seller
true, accurate and complete copies of any final written reports relating to
the Property prepared for or on behalf of Buyer by any third party (without
representation or warranty of any kind by Buyer with respect thereto) and
in the event of termination hereunder, shall return all documents and other
materials furnished by Seller hereunder.  Buyer shall keep all information
or data received or discovered in connection with any of the inspections,
reviews or examinations strictly confidential.  If, on or before the
expiration of the Due Diligence Period, based upon such review, examination
or inspection, Buyer shall determine in its sole and absolute discretion
that it intends to proceed with the acquisition of the Property, then Buyer
shall promptly notify Seller and Escrow Holder of such determination in
writing (such notice being herein called the "Approval Notice") and
concurrently therewith Buyer shall deliver the Additional Escrow Deposit to
Escrow Holder (and thereafter, Buyer shall have no further right to
terminate this Agreement pursuant to this paragraph 4B).  If, however, on
or before the expiration of the Due Diligence Period, based upon such
review, examination or inspection, Buyer shall determine in its sole and
absolute discretion that it no longer intends to acquire the Property, then
Buyer shall promptly notify Seller of such determination in writing (such
notice being herein called the "Termination Notice"), whereupon the Escrow
Deposit shall be returned to Buyer and this Agreement, and the obligations
of the parties hereunder, shall terminate.  In the event that, on or before
the expiration of the Due Diligence Period, Buyer shall fail to have
delivered the Approval Notice to Seller (and concurrently therewith deposit
the Additional Escrow Deposit with Escrow Holder as provided for in this
Agreement), Buyer shall be deemed to have elected not to proceed with the
acquisition of the Property whereupon the Escrow Deposit shall be returned
to Buyer and this Agreement, and the obligations of the parties hereunder,
shall terminate.

           C.    Estoppel Certificates.  Receipt of estoppel certificates
("Tenant Estoppel Certificates"), from all tenants leasing more than 10,000
square feet of space, together with such additional tenants as may be
required so that Tenant Estoppel Certificates are received from tenants
leasing, in the aggregate, not less than 80% of the net rentable square
feet of space covered by leases in effect as of the date hereof, shall be a
condition precedent to Buyer's obligation to purchase the Property
hereunder.  Each Tenant Estoppel Certificate shall either be substantially
in the form provided in Exhibit "C" attached hereto and made a part hereof
or in the form, if any, prescribed in the applicable tenant lease and shall
disclose no material defaults or other adverse information which is
materially inconsistent with the leases or the "Rent Roll" (as hereinafter
defined).  Seller's sole obligation hereunder shall be to utilize
commercially reasonable efforts to obtain a Tenant Estoppel Certificate
from each tenant at the Property (such reasonable efforts obligations not
including any obligation to institute legal proceedings or to expend monies
therefor), but such obligation shall not affect the provision of such
Tenant Estoppel Certificates as a condition precedent to closing.  Without


<PAGE>


limiting the condition that Buyer received the Estoppel Certificates
described above, Seller shall deliver at the Closing a Seller's estoppel
certificate ("Seller's Estoppel") for each tenant that does not deliver a
Tenant Estoppel Certificate.  The Seller's Estoppel shall state that (i)
attached to such estoppel is a true, correct and complete copy of the
applicable tenant lease (including all amendments or modifications
thereto), (ii) there is no default under the applicable lease, (iii) the
rent and other charges payable under the applicable lease, (iv) the
commencement and termination date of the applicable lease, and (v) the
suite number and square footage covered by the applicable lease.  The
Seller's Estoppel shall be subject to the limitations on survival contained
in paragraph 7C hereof and the limitations on liability contained in
paragraph 9B hereof.

     5.    Closing Procedure.  The sale and purchase herein provided shall
be consummated on the Closing Date through escrow ("Escrow") with the Title
Company.  As used herein, _xe "\"Closing Date\":"_"Closing Date" means
December 30, 1997, or such earlier date as may be agreed upon by Buyer and
Seller; provided, however, if any of the conditions to Closing set forth in
this Agreement is not satisfied on or before the Closing Date or if Buyer
shall claim that Seller in is default or has otherwise breached its
obligations under this Agreement, Seller shall have the right, at its sole
option, to extend the Closing Date for up to ten (10) days in order to
attempt to satisfy such conditions or cure such defaults or breaches.

           A.    Escrow.  On or before the Closing Date, the parties shall
deliver to Title Company the documents described below.  Such deliveries
shall be made pursuant to escrow instructions (_xe "\"Escrow

and specifications, keys and other applicable management material
respecting the Property (provided the foregoing items may be delivered by
Seller causing the same to be retained at the Property);

           (e)   Notices to tenants in form reasonably acceptable to
Seller and Buyer informing tenants of the sale of the Property to Buyer and
the transfer of security deposits ("Tenant Notices");

           (f)   A signed "Closing Statement" (as hereinafter defined);

           (g)   Evidence reasonably satisfactory to Buyer and Title

<PAGE>


           (h)   Such additional documents as may be reasonably required
by Buyer and Title Company in order to consummate the transactions

           (2)   Buyer Deliveries.  Buyer shall deliver to Escrow the
following:

           (a)   The Closing Payment in immediately available federal

           (e)   Such additional documents as may be reasonably required

obligations of, Buyer in a manner not otherwise provided for herein).

           (3)   Delivery to Parties.  Upon the satisfaction of the
conditions set forth in the Escrow Instructions, then (x) the Deed shall be

(y) the Closing Payment (and the Escrow Deposit) shall be delivered by

           C.    Closing Costs.  Seller shall pay (i) the title insurance
premium for the Owner's Policy at a rate not in excess of standard issue
rates (but excluding any additional or extended coverage or endorsements
requested by Buyer), (ii) any documentary transfer tax imposed by the
County of Santa Clara and attributable to the Deed (the "County Tax"),
(iii) one-half of any local transfer taxes (other than the County Tax)
attributable to the Deed, (iv) the costs to update the Survey and (v) one-
half of any escrow or recording charges attributable to the Deed.  Buyer
shall pay (i) the costs of any ALTA or so called "extended coverage" in
connection with, or endorsements to, the Owner's Policy, together with the
cost of any other title insurance coverage (such as lender's insurance
policies), (ii) one-half of any local transfer taxes (other than the County
Tax) attributable to the Deed, (iii) one-half of any escrow or recording
charges and (iv) all fees, costs or expenses incurred by Buyer in
connection with Buyer's due diligence reviews hereunder.  Each of Seller
and Buyer shall pay its own attorneys' fees and its respective share of
prorations as hereinafter provided.  Notwithstanding the foregoing, in the
event the sale contemplated hereby does not close on the Closing Date, then
each party shall pay all costs incurred by it.

           D.    Prorations.

           (1)   Items to be Prorated.  The following shall be prorated
between Seller and Buyer such that items of income and expense through the
day prior to the Closing Date shall be allocated to Seller, and items of
income and expense for the Closing Date and thereafter shall be allocated
to Buyer:



<PAGE>


           (a)   All real estate taxes and assessments on the Property for
the current year on a per diem basis.  In no event shall Seller be charged
with or be responsible for any increase in the taxes on the Property
resulting from the sale of the Property or from any improvements made or
leases entered into on or after the Closing Date.  If any assessments on
the Property are payable in installments, then the installment for the
current period shall be prorated (with Buyer assuming the obligation to pay
any installments due after the Closing Date).

           (b)   All fixed and additional rentals under the leases,
security deposits and other tenant charges.  Seller shall deliver or
provide a credit in an amount equal to all prepaid rentals for periods
after the Closing Date and all refundable security deposits (to the extent
the foregoing are held by Seller and are not applied or forfeited prior to
the Closing Date) to Buyer on the Closing Date.  Rents which are delinquent
as of the Closing Date shall not be prorated on the Closing Date.  Buyer
shall include such delinquencies in its normal billing and shall diligently
pursue the collection thereof in good faith after the Closing Date (but
Buyer shall not be required to litigate or declare a default in any lease).

To the extent Buyer receives rents on or after the Closing Date, such
payments shall be applied first toward then current rent owed to Buyer in
connection with the applicable lease for which such payments are received,
and any excess monies received shall be applied toward the payment of any
delinquent rents, with Seller's share thereof being promptly delivered to
Seller within fifteen (15) days after receipt of the same by Buyer.  Buyer
may not waive any delinquent rents nor modify a lease so as to reduce or
otherwise affect amounts owed thereunder for any period in which Seller is
entitled to receive a share of charges or amounts without first obtaining
Seller's written consent.  Seller hereby reserves the right to pursue any
damage remedy (but in no action for eviction or lease termination) against
any tenant owing delinquent rents and any other amounts to Seller.  Buyer
shall reasonably cooperate with Seller in any collection efforts hereunder
(but shall not be required to litigate or declare a default in any lease).
With respect to delinquent rents and any other amounts or other rights of
any kind respecting tenants who are no longer tenants of the Property as of
the Closing Date, Seller shall retain all rights relating thereto.
Reimbursement amounts due Seller under any reciprocal easement agreements
affecting the Property shall be prorated in the same manner as rents
hereunder.

           (c)   All operating expenses, including those under any
reciprocal easement agreements affecting the Property.

           (2)   Calculation.  The prorations and payments shall be made
on the basis of a written statement submitted to Buyer and Seller by Escrow
Holder prior to the Close of Escrow and approved by Buyer and Seller.  In
the event any prorations or apportionments made under this subparagraph D
shall prove to be incorrect for any reason, then any party shall be
entitled to an adjustment to correct the same provided written notice of
such inaccuracy and request for correction is given within six months after
the date hereof.  Any item which cannot be finally prorated because of the
unavailability of information shall be tentatively prorated on the basis of
the best data then available and reprorated when the information is
available.  The obligations of Seller and Buyer under this paragraph 5D(2)
shall survive the closing until June 15, 1998 (and all reprorations shall
be finalized prior to such date).



<PAGE>


     6.    Risk of Loss.  If any of the Property is damaged or destroyed
prior to the Closing Date, and such damage or destruction would cost less
than Two Hundred Fifty Thousand Dollars ($250,000) to repair or restore and
is covered by insurance (other than the deductible amount, if any), then
this Agreement shall remain in full force and effect and Buyer shall
acquire the Property upon the terms and conditions set forth herein.  In
such event, Buyer shall receive a credit against the Purchase Price equal
to any deductible under Seller's property damage insurance policy and
Seller shall assign to Buyer all of Seller's right, title and interest in
and to all proceeds of insurance other than amounts expended to repair any
damage or destruction and loss of rent proceeds attributable to the period
prior to Closing on account of such damage or destruction.  If any of the
Property is damaged or destroyed prior to the Closing, and the cost of
repair would exceed Two Hundred Fifty Thousand Dollars ($250,000), or if
such cost of repair would not exceed $250,000 but such casualty damage is
uninsured (and Seller shall elect not to credit Buyer with the amount
necessary to repair the same, Seller having the right but not the
obligation to so credit), or condemnation proceedings are commenced against
any of the Property, then, Buyer shall have the right, at its election,
either to terminate this Agreement or to not terminate this Agreement and
purchase the Property.  Buyer shall have the sooner to occur of the Closing
Date or ten (10) business days after Seller notifies Buyer in writing that
an event described in the immediately preceding sentence has occurred to
make such election by delivery to Seller of an election notice (the
"Election Notice").  Buyer's failure to deliver the Election Notice within
such period shall be deemed an election to terminate this Agreement.  If
this Agreement is terminated by delivery of notice of termination to
Seller, then Buyer and Seller shall each be released from all obligation
hereunder, except as otherwise expressly provided to the contrary herein.
If Buyer continues this Agreement, Buyer shall receive a credit against the
Purchase Price equal to any deductible under Seller's property damage
insurance policy and Seller shall assign to Buyer all of Seller's right,
title and interest in and to all insurance proceeds (other than amounts
expended to repair any damage or destruction and any loss of rent proceeds
attributable to the period prior to the Closing, which shall remain the
property of Seller) or condemnation awards on account of such damage,

           A.    Representations, Warranties and Covenants of Seller.

                 (1)  General Disclaimer.  Except as specifically set
forth in Paragraph 7A(2) below, the sale of the Property hereunder is and
will be made on an "as is" basis, without representations and warranties of
any kind or nature, express, implied or otherwise, including, but not

opportunity to examine, review and inspect all matters which in Buyer in
its sole and absolute judgment bears upon the Property and its value and
suitability for Buyer's purposes.  Except as to matters specifically set
forth in Paragraph 7A(2) below, Buyer will acquire the Property solely on
the basis of its own physical and financial examinations, reviews and
inspections and the title insurance protection afforded by the Owner's
Policy.  Without limitation thereon, Buyer agrees that it will not pursue
any rights of contribution or other rights or remedies against Seller under
the Comprehensive Environmental Response, Compensation and Liability Act
("CERCLA") or any other applicable environmental laws, rules or
regulations.  The provisions of the preceding sentence shall not in any way
limit Buyer's right to seek contribution or other rights or remedies
against Seller under the Comprehensive Environmental Response, Compensation
and Liability Act ("CERCLA") or any other applicable environmental laws,
rules or regulations in the event that any claim is made against Buyer
under the Comprehensive Environmental Response, Compensation and Liability
Act ("CERCLA") or any other applicable environmental laws, rules or
regulations by any governmental agency or any third party based on any
facts or circumstances arising prior to the Closing (such rights or
remedies in all events being subject to the limitations on liabilities set
forth in this Agreement, including those set forth in paragraph 9B hereof).

           (2)   Limited Representations and Warranties of Seller.  Seller
hereby represents and warrants that, except as set forth in Exhibit "F"
attached hereto and made a part hereof, Seller has no knowledge that any of
the following statements is untrue (and, for this purpose, Seller's
knowledge shall mean only the present actual knowledge of Andrea Backman
without any duty to investigate (other than to make inquiry of Bob
Bronstein of Seller's third party property management company) and with any
imputed or constructive knowledge being excluded):

           (a)   Rent Roll.  Attached as Exhibit "G" and made a part
hereof is a true, complete and accurate list, as of the date thereof, of
all tenant leases respecting the Property.  Seller has made available, or
during the Due Diligence Period will make available, to Buyer true and
correct copies of the tenant leases.  Seller has not received any written
notice of a material default under any of such tenant leases that remains
uncured.  Notwithstanding anything to the contrary contained herein, if any
of the foregoing matters are confirmed as correct in any Tenant Estoppel
Certificate which may be delivered hereunder and thereafter the applicable
tenant takes an inconsistent position with respect to such matters, Buyer
shall look solely to such tenants for any liability or obligation in
connection with such matters.

           (b)   Litigation.  There is no pending action, litigation,
condemnation or other proceeding against the Property or against Seller
with respect to the Property.

           (c)   Compliance.  Seller has received no written notice from
any governmental authority having jurisdiction over the Property to the
effect that the Property is not in compliance with applicable laws and
ordinances.

           (d)   Agreements Affecting the Property.  Other than the leases
or matters of record, Seller has not entered into any contracts or other
agreements (other than as set forth in this Agreement) relating to the
Property which will be in force on the Closing Date, except for the service
agreements described in Exhibit "H-1" (the "Service Agreements"), the
parking easements and agreements described in Exhibit "H-2" (the "Parking
Agreements") and the rooftop agreements described in Exhibit "H-3" (the
"Rooftop Agreements").  Seller has not received any written notice of any
default under any of the foregoing agreements that remains uncured.



<PAGE>


           (e)   Due Authority.  This Agreement and all agreements,
instruments and documents herein provided to be executed or to be caused to
be executed by Seller are and on the Closing Date will be duly authorized,
executed and delivered by and are binding upon Seller.  Seller is a
partnership, duly organized and validly existing under the laws of the
State of Illinois, and is duly authorized and qualified to do all things
required of it under this Agreement.  Seller has the capacity and authority
to enter into this Agreement and consummate the transactions herein
provided.

           (f)   Environmental Matters.  Except as set forth in the
reports described in Exhibit "I" attached hereto and made a part hereof
(the "Environmental Reports"), Seller has received no written notice of the
existence, deposit, storage, removal, burial or discharge of any material
known to Seller to be a "Hazardous Material" at, upon, under or within the
Property, in an amount which would, as of the date hereof, give rise to an
"Environmental Compliance Cost". The term "Hazardous Material" shall mean
(i) asbestos, petrochemicals or hydrocarbons and any chemicals, flammable
substances or explosives, any radioactive materials (including radon), any
hazardous wastes or substances which have, as of the date hereof, been
determined by any applicable Federal, State or local government law to be
hazardous or toxic by the U.S. Environmental Protection Agency, the U.S.
Department of Transportation, and/or any instrumentality now or hereafter
authorized to regulate materials and substances in the environment which
has jurisdiction over the Property ("Environmental Agency"), and (ii) any
oil, petroleum or petroleum derived substance, any drilling fluids,
produced waters and other wastes associated with the exploration,
development or production of crude oil, which materials listed under items
(i) and (ii) above cause the Property (or any part thereof) to be in
violation of any applicable environmental laws or the regulations of any
Environmental Agency; provided, however, that the term "Hazardous Material"
shall not include motor oil and gasoline contained in or discharged from
vehicles not used primarily for the transport of motor oil or gasoline or
any materials such as cleaning supplies, photocopy equipment supplies and
other similar materials in quantities commonly stored, found or maintained
for similar uses in properties similar to the Property.  The term
"Environmental Compliance Cost" means any out-of-pocket cost, fee or
expense incurred directly to satisfy any requirement imposed by an
Environmental Agency to bring the Property into compliance with applicable
Federal, State and local laws and regulations directly relating to the
existence on the Property of any Hazardous Material.  Buyer hereby
acknowledges that it is acquiring the Property subject to the matters
disclosed in the Environmental Reports, and Buyer shall at Closing, assume
the obligations for, and release Seller from any liability relating to
(whether under local, state or federal law), any matters disclosed in the
Environmental Reports; provided, however, nothing in the foregoing shall
constitute an indemnification by Buyer in favor of Seller for any third
party claims with respect to such matters and in the event that any claim
is made against Buyer by any governmental agency or any third party based
on any violation of environmental laws or any contamination of the Property
by Hazardous Materials prior to the Closing Buyer shall be entitled to seek
contribution or indemnification from Seller on account thereof in
accordance with any applicable laws, rules, regulations or statutes (such
rights or remedies in all events being subject to the limitations on
liabilities contained in this Agreement, including those set forth in
paragraph 9B hereof).

           (g)   Options.  Seller has not given or granted (nor does
Seller have any knowledge of the existence of) any rights of first refusal,
rights of first offer or other options to acquire the Property in whole or
in part.

           (h)   Structural Condition.  Except as otherwise disclosed to
Buyer, Seller has not received any written notice from any governmental
authorities or any third party structural reports or studies that indicate
that there are any material structural problems or deficiencies in the
Property or any part thereof.

           B.    Representations and Warranties of Buyer.  Buyer hereby
represents and warrants that this Agreement and all agreements, instruments
and documents herein provided to be executed or to be caused to be executed
by Buyer are and on the Closing Date will be duly authorized, executed and
delivered by and are binding upon Buyer; Buyer is a limited liability
company, duly organized and validly existing and in good standing under the
laws of the State of Delaware, and is duly authorized and qualified to do
all things required of it under this Agreement; and Buyer has the capacity
and authority to enter into this Agreement and consummate the transactions
herein provided.

           C.    Survival.  Any cause of action of a party for a breach of
the foregoing representations and warranties shall survive until
November 15, 1998, at which time such representations and warranties (and
any cause of action resulting from a breach thereof not then in litigation)
shall terminate.  Notwithstanding the foregoing, if Buyer shall have actual
knowledge as of the Closing Date that any of the representations or
warranties of Seller contained herein are false or inaccurate or that
Seller is in breach or default of any of its obligations under this
Agreement, and Buyer nonetheless closes the transactions hereunder and
acquires the Property, then Seller shall have no liability or obligation
respecting such false or inaccurate representations or warranties or other
breach or default (and any cause of action resulting therefrom shall
terminate upon such closing hereunder).

           D.    Interim Covenants of Seller.  Until the Closing Date or
the sooner termination of this Agreement:

           (1)   Seller shall maintain the Property in the same manner as
prior hereto pursuant to its normal course of business (such maintenance
obligations not including extraordinary capital expenditures or
expenditures not incurred in such normal course of business), subject to
reasonable wear and tear and further subject to destruction by casualty or
other events beyond the control of Seller.

           (2)   Seller shall not enter into any additional service
contracts or other similar agreements without the prior consent of Buyer,
except those deemed reasonably necessary by Seller which are cancelable on
thirty (30) days' notice.

           (3)   Seller shall have the right to continue to offer the
Property for lease in the same manner as prior hereto pursuant to its
normal course of business and, upon request, shall keep Buyer reasonably
informed as to the status of leasing prior to the Closing Date.  After the
Effective Date, Seller shall not enter into any new leases or material
modifications of existing leases thereafter without the consent of Buyer
(which consent, may be given or withheld in Buyer's sole and absolute
discretion).  In connection therewith, Buyer shall respond to Seller's
request to enter into a new lease or a material modification within
five (5) business days after Buyer's receipt of such request.  In the event
that Buyer fails to respond to such a request within such five (5) business
day period, Buyer shall be deemed to have approved the new lease or
material modification.  In no event shall Seller have any obligation to
enter into any new lease or modify any existing lease unless Buyer shall
agree to pay or reimburse Seller on the Closing Date for all landlord
costs, legal costs, tenant improvement costs and leasing commissions
incurred by Seller under or in connection therewith.

     9.    DISPOSITION OF DEPOSIT.  IF THE TRANSACTION HEREIN PROVIDED
SHALL NOT BE CLOSED BY REASON OF SELLER'S DEFAULT UNDER THIS AGREEMENT OR
THE FAILURE OF SATISFACTION OF THE CONDITIONS DESCRIBED IN PARAGRAPH 4
HEREOF OR THE TERMINATION OF THIS AGREEMENT IN ACCORDANCE WITH PARAGRAPH 6
HEREOF, THEN THE ESCROW DEPOSIT SHALL BE RETURNED TO BUYER, AND NEITHER
PARTY SHALL HAVE ANY FURTHER OBLIGATION OR LIABILITY TO THE OTHER;
PROVIDED, HOWEVER, IF THE TRANSACTIONS HEREUNDER SHALL FAIL TO CLOSE BY
REASON OF SELLER'S DEFAULT, AND BUYER SHALL BE READY, WILLING AND ABLE TO
CLOSE, THEN BUYER SHALL BE ENTITLED TO SPECIFICALLY ENFORCE THIS AGREEMENT;
AND PROVIDED FURTHER THAT, IF FOLLOWING OR IN CONNECTION WITH A DEFAULT BY
SELLER, SELLER SHALL TAKE ACTIONS SO AS TO EITHER PREVENT THE AVAILABILITY
OF SPECIFIC PERFORMANCE TO BUYER OR WHICH MATERIALLY ADVERSELY IMPACT THE
VALUE OF THE PROPERTY SUCH THAT SPECIFIC PERFORMANCE WOULD NOT PROVIDE
BUYER SUBSTANTIALLY WITH THE BENEFITOF THE BARGAIN CONTEMPLATED IN THIS
AGREEMENT, AND THE OTHER CONDITIONS SET FORTH ABOVE SHALL BE SATISFIED,
BUYER SHALL BE ENTITLED TO A RETURN OF THE ESCROW DEPOSIT AND REIMBURSEMENT
OF ITS ACTUAL OUT-OF-POCKET COSTS PAID TO THIRD PARTIES IN CONNECTION WITH
THE TRANSACTIONS HEREUNDER (SUCH REIMBURSEMENT NOT TO EXCEED $150,000 IN
THE AGGREGATE).  EXCEPT AS SET FORTH ABOVE,  NO OTHER ACTIONS, FOR DAMAGES
OR OTHERWISE, SHALL BE PERMITTED IN CONNECTION WITH ANY DEFAULT BY SELLER
IN THE EVENT THE TRANSACTIONS HEREUNDER SHALL FAIL TO CLOSE.  IN THE EVENT
THE TRANSACTION HEREIN PROVIDED SHALL NOT CLOSE FOR ANY REASON OTHER THAN
THE FAILURE OF SATISFACTION OF THE CONDITIONS DESCRIBED IN PARAGRAPH 4
HEREOF OR THE TERMINATION OF THIS AGREEMENT IN ACCORDANCE WITH PARAGRAPH 6
HEREOF OR THE DEFAULT OF SELLER, THEN THE ESCROW DEPOSIT SHALL BE DELIVERED
TO SELLER AS FULL COMPENSATION AND LIQUIDATED DAMAGES UNDER AND IN
CONNECTION WITH THIS AGREEMENT.  IN THE EVENT THE TRANSACTION HEREIN
PROVIDED SHALL CLOSE, THE ESCROW DEPOSIT SHALL BE APPLIED AS A PARTIAL
PAYMENT OF THE PURCHASE PRICE.  IN CONNECTION WITH THE FOREGOING, THE
PARTIES RECOGNIZE THAT SELLER WILL INCUR EXPENSE IN CONNECTION WITH THE
TRANSACTION CONTEMPLATED BY THIS AGREEMENT AND THAT THE PROPERTY WILL BE
REMOVED FROM THE MARKET; FURTHER, THAT IT IS EXTREMELY DIFFICULT AND
IMPRACTICABLE TO ASCERTAIN THE EXTENT OF DETRIMENT TO SELLER CAUSED BY THE
BREACH BY BUYER UNDER THIS AGREEMENT AND THE FAILURE OF THE CONSUMMATION OF
THE TRANSACTION CONTEMPLATED BY THIS AGREEMENT OR THE AMOUNT OF
COMPENSATION SELLER SHOULD RECEIVE AS A RESULT OF BUYER'S BREACH OR
DEFAULT.  IN THE EVENT THE SALE OF THE PROPERTY SHALL NOT BE CONSUMMATED ON
ACCOUNT OF BUYER'S DEFAULT, THEN THE RETENTION OF THE ESCROW DEPOSIT SHALL
BE SELLER'S SOLE AND EXCLUSIVE REMEDY UNDER THIS AGREEMENT BY REASON OF
SUCH DEFAULT, SUBJECT TO THE PROVISIONS OF PARAGRAPH 9I HEREOF.

agreement made or entered into under or pursuant to the provisions of this
Agreement, or any amendment or amendments to any of the foregoing made at

and assigns and, without limitation, all other persons and entities, shall
look solely to Seller's assets for the payment of any claim or for any
performance, and Buyer, on behalf of itself and its successors and assigns,

(and neither Buyer nor any of its successors or assigns shall have any
right to collect, enforce or proceed against or with respect to any such
negative capital account of partner's obligation to restore or contribute).

construing this Agreement.  Each party acknowledges that such party and its
counsel, after negotiation and consultation, have reviewed and revised this
Agreement.  As such, the terms of this Agreement shall be fairly construed

in the interpretation of this Agreement or any amendments, modifications or

its rights or obligations under this Agreement without the prior written
consent of Seller, (in which event such transferee shall assume in writing
all of the transferor's obligations hereunder, and transferor shall

thereafter) provided, however, effective at, and conditioned upon, Closing
hereunder, Buyer may assign its interest in this Agreement to an entity
affiliated or associated with David Taran and/or Stuart Shiff.  No consent
given by Seller to any transfer or assignment of Buyer's rights or
obligations hereunder shall be construed as a consent to any other transfer
or assignment of Buyer's rights or obligations hereunder.  No transfer or
assignment in violation of the provisions hereof shall be valid or

           I.    Legal Costs.  The parties hereto agree that they shall
pay directly any and all legal costs which they have incurred on their own
behalf in the preparation of this Agreement, all deeds and other agreements
pertaining to this transaction and that such legal costs shall not be part

entitled to recover reasonable attorneys' fees, expenses and costs of
investigation actually incurred.  The foregoing includes, but is not
limited to, attorneys' fees, expenses and costs of investigation
(including, without limitation, those incurred in appellate proceedings),
costs incurred in establishing the right to indemnification, or in any
action or participation in, or in connection with, any case or proceeding
under Chapter 7, 11 or 13 of the Bankruptcy Code (11 United States Code
Sections 101 et seq.), or any successor statutes.

           J.    Counterparts; Facsimile Signatures.  This Agreement may
be executed in one or more counterparts, each of which shall be deemed an
original, but all of which shall constitute one and the same document.
Each party hereto (i) has agreed to permit the use, from time to time and
where appropriate, of telecopied signatures in order to expedite the
transaction contemplated by this Agreement, (ii) intends to be bound by its
respective telecopied signature, (ii) is aware that the other party will
rely on the telecopied signature, and (iv) acknowledges such reliance and
waives any defenses to the enforcement of documents and notices effecting
the transaction contemplated by this Agreement based on the fact that a
signature or notice was sent by telecopy.

           K.    Waiver of Jury Trial and Consent to Venue.  To the
fullest extent permitted by law, Buyer and Seller hereby waive their
respective right to trial by jury in any action, proceeding and/or hearing
on any matter whatsoever arising out of, or in any way connected with this
Agreement or any matter arising hereunder.  Neither party will seek to

County of Santa Clara or the federal District Court sitting in San Jose.
Each party acknowledges that it has received the advice of counsel with
