                  1.1      PROPERTY. Subject to the terms and conditions hereof,
Seller hereby agrees to sell, convey and assign to Buyer, and Buyer hereby
agrees to purchase and accept from Seller on the Closing Date (as defined below)

                                       1
<PAGE>

                  1.3      ASSIGNMENT. In addition, Seller shall convey and
assign to Buyer all of the right, title and interest of Seller, if any, in and
to (i) the lease(s) scheduled on EXHIBIT 1.3 (i) attached hereto (the
"LEASE(S)") and all lease(s) approved by Buyer subject to Section 10.3 below,
together with any and all security deposits in Seller's possession in connection
therewith; (ii) all assignable service contracts and other agreements, if any,
relating to the Real Property or Personal Property to be assumed by Buyer as
described on EXHIBIT 1.3 (ii) attached hereto (collectively the "SERVICE
CONTRACTS"); (iii) all assignable current licenses, permits, certificates of
occupancy, approvals and entitlements issued or granted in connection with the
Real Property as well as any and all assignable development rights and any other
intangible rights, interests or privileges relating to or used in connection
with the Real Property; (iv) any assignable right to use the current names of
the Real Property, logos, trademarks, tradenames and symbols and promotional
materials; and (v) all transferrable warranties, guarantees or sureties relating
to the Real Property or the Personal Property. Such assignment shall be made
pursuant to the Assignment and Assumption Agreement in the form described in
Section 8.1.3 below ("ASSIGNMENT"). All of the above interests as described in
clauses (iii), (iv) and (v) of this Section 1.3 shall sometimes be referred to
collectively as the "INTANGIBLE PROPERTY".

                  1.4      EXCLUDED PROPERTY. Notwithstanding anything to the
contrary set forth herein, the Property being conveyed pursuant to this
Agreement does not include (and Seller expressly reserves all rights with
respect thereto) any existing claims or causes of action with respect to the
Property to the extent attributable to the period prior to the Closing Date
including, without limitation, any tax rebates attributable to the period prior
to the Closing and claims against existing tenants with respect to matters
accruing prior to the Closing Date or previous tenants. The provisions of this
Section 1.4 shall not be construed, however, to restrict the ability of Buyer
following the Closing Date to deal with any existing tenants of the Real
Property or to restrict the Buyer following the Closing Date from pursuing any
and all remedies in connection with existing hazardous materials on, in or about
the Real Property.

         2.       PURCHASE PRICE. Buyer shall pay as the total purchase price
for the Property ("PURCHASE PRICE") the sum of Five Million Four Hundred
Thousand Dollars ($5,400,000). The Purchase Price shall be paid as follows:

                  2.1      DEPOSIT. On or before one (1) business day following
the Effective Date, Buyer shall cause One Hundred Thousand Dollars ($100,000)
(the "DEPOSIT #1") in immediately available funds to be delivered into Escrow
(as defined below). On or before one (1) business day following the Due
Diligence Date (as defined below) provided that Buyer has given the Approval
Notice (as defined below), Buyer shall cause an additional One Hundred Thousand
Dollars ($100,000) (the "DEPOSIT #2") in immediately available funds to be
delivered into Escrow. The "DEPOSIT" shall refer to the sum of the Deposit #1
and Deposit #2 as each of said amounts are received by Escrow. The failure of
Buyer to timely deliver any of the respective Deposits shall be a material
default, and shall entitle Seller, at Seller's sole option, to terminate this
Agreement immediately by giving written notice of such termination to Buyer and
the Title Company (as defined below);

                  2.2      INTEREST ON DEPOSIT. The Deposit shall be held by the
Title Company as an earnest money deposit towards the Purchase Price. The
Deposit shall be held in Escrow in accordance with the provisions of this
Agreement in a federally insured interest bearing account or other investment
suitable for daily investment reasonably acceptable to Seller and Buyer (and in
any

                                       2
<PAGE>

event with any risk of loss for the account of Buyer) with any interest accruing
thereon to be paid or credited, except as otherwise provided in this Agreement,
to Buyer. The term "Deposit" shall include any and all interest then accrued;

                  2.3      DISPOSITION OF DEPOSIT. At the Closing (as defined
below) the Deposit shall be applied and credited toward the payment of the
Purchase Price. If Escrow does not close, and this Agreement is terminated in a
manner governed by Sections 7.3 or 13, the Deposit will be disbursed to Buyer as
provided in such Sections. If the Escrow does not close and neither Section 7.3
nor Section 13 applies, the Deposit shall be returned to Buyer unless the
provisions of Section 18.1 are applicable, in which case the disposition of the
Deposit shall be governed by the provisions of Section 18.1; and

                  2.4      CASH BALANCE. On or before the Closing, Buyer shall
deliver into Escrow in immediately available funds the balance of the Purchase
Price. The Purchase Price, net of any prorations and closing costs to be paid by
Seller as provided in this Agreement, shall be paid by the Title Company to
Seller on the Closing Date by federal wire transfer of immediately available
funds to a bank account(s) designated by Seller in a written notice to the Title
Company given prior to the Closing.

         3.       TITLE.

                  3.1      VESTING OF TITLE. At Closing, Seller shall convey fee
simple title to the Real Property to Buyer by execution and delivery of the Deed
(as defined below). Issuance by the Title Company (or an unconditional
commitment to issue) as of the Closing of the Buyer's Title Policy (as defined
below) shall constitute evidence of delivery of title by Seller.

                  3.2      BUYER'S TITLE INSURANCE. At Closing, the Title
Company shall issue to Buyer a CLTA standard coverage owner's form of title
insurance policy in the amount of the Purchase Price insuring that fee simple
title to the Real Property is vested in Buyer subject only to the Permitted
Exceptions (as defined below) ("BUYER'S TITLE POLICY"). Buyer shall be entitled
to request that the Title Company provide an ALTA title insurance policy and/or
such endorsements to the Buyer's Title Policy as Buyer may reasonably require,
provided that such ALTA policy and/or endorsements shall be at no cost or
additional liability to Seller and the Closing shall not be delayed as a result
of Buyer's request.

                  3.3      PERMITTED EXCEPTIONS. As a condition precedent of
Buyer's obligations as provided in Section 7.2.4 but not as a covenant of
Seller, Seller shall convey the Property and Buyer shall accept the Property
subject to the following matters, which are collectively referred to as the
"PERMITTED EXCEPTIONS":

                           3.3.1    all exceptions to title shown in the Title
Report (as defined below) as it may be amended and on the Survey (as defined
below) that are approved or deemed approved by Buyer as provided in Section 6.3
hereof;

                           3.3.2    the lien of non-delinquent real and personal
property taxes and assessments;

                           3.3.3    the rights of the tenant(s) under the
Lease(s);

                                       3
<PAGE>

                           3.3.4    the Service Contracts, if any, to be assumed
by Buyer;

                           3.3.5    local, state and federal laws, ordinances or
governmental regulations, including but not limited to, building and zoning
laws, ordinances and regulations, now existing or hereafter in effect with
respect to the Real Property;

                           3.3.6    matters affecting the condition of title
created by or with the written consent of Buyer;

                           3.3.7    water rights, and claims of title to water,
whether or not shown by the public records;

                           3.3.8    unless Buyer elects to obtain an ALTA policy
of title insurance, discrepancies, conflicts in boundary lines, shortages in
area, encroachments, and any state of facts which inspection of the Real
Property would disclose and which are not shown by the public records; and

                           3.3.9    standard printed exclusions generally
included in a CLTA owner's policy (or ALTA owner's policy, as the case may be).

         4.       ESCROW.

                  4.1      OPENING OF ESCROW. Seller shall deliver a copy of a
fully executed counterpart of this Agreement into escrow ("ESCROW") to be
established at Chicago Title Company, 388 Market Street, Suite 1350, San
Francisco, California 94111, Attention: Nicole Carr ("TITLE COMPANY") on or
before three (3) days following the Effective Date.

                  4.2      INSTRUCTIONS TO TITLE COMPANY. Seller and Buyer shall
each be entitled to submit escrow instructions to the Title Company in
connection with the Closing of the Escrow. Seller and Buyer shall in addition
execute such further escrow instructions as the Title Company may reasonably
require in connection with the Closing so long as such instructions are
consistent with the provisions of this Agreement and the escrow instructions of
Seller and Buyer. In the event of any conflict between the terms and conditions
of this Agreement and the provisions of any escrow instructions prepared by
Seller, Buyer or the Title Company, the terms and conditions of this Agreement
shall control.

         5.       CLOSING.

                  5.1      CLOSING. The purchase and sale of the Property as
contemplated by this Agreement, including but not limited to the recordation of
the Deed and the completion of the other matters required by this Agreement to
be done contemporaneously (the "CLOSING") shall occur on a date selected by
Seller (with written notice to Buyer no less than three (3) business days prior
to the selected date), but shall occur no sooner than Monday, December 11, 2000
and no later than Wednesday, January 3, 2001. The date on which the Closing
actually occurs shall be referred to as the "CLOSING DATE".

                  5.2      FAILURE TO CLOSE. If the Closing does not occur on or
before the date set forth in Section 5.1 above (as such date may be extended
pursuant to the express provisions of this Agreement), then in the absence of a
written agreement between the parties to extend the Closing

                                       4
<PAGE>

Date, either party hereto (so long as such party is not then in default pursuant
to this Agreement), without waiving any rights it may otherwise have pursuant to
the Agreement, may elect to terminate this Agreement by giving written notice of
such termination to the other and to the Title Company.

         6.       DUE DILIGENCE.

                  6.1      DUE DILIGENCE PERIOD. The period commencing as of the
Effective Date and continuing through 5:00 p.m. PST, Friday, December 8, 2000
(the "DUE DILIGENCE DATE") shall be referred to as the "DUE DILIGENCE PERIOD".

                  6.2      AVAILABLE INFORMATION. Seller shall make available to
Buyer the following documents and materials (collectively, the "DUE DILIGENCE
MATERIALS").

                           6.2.1    DELIVERED MATERIALS. Within two (2) days
following the Effective Date, Seller will deliver or cause to be delivered to
Buyer copies of all of the documents and materials relating to the Property
listed on EXHIBIT 6.2.1 attached hereto provided that the same is not
confidential or proprietary in nature. Seller has not undertaken any independent
investigation as to the truth or accuracy of the documents and materials to be
delivered and is providing same solely as an accommodation to Buyer.

                           6.2.2    PROPERTY FILES. Seller shall make available
to Buyer and Buyer's agents and representatives, upon reasonable notice and
during normal business hours, all files in the possession of Seller, or in
possession of Seller's property manager, if any, relating to the ownership,
operation, construction, use or occupancy of the Property, or any portion of the
Property. Buyer, at its expense, may make photocopies of such material relative
to the Property as Buyer may determine.

                           6.2.3    RESTRICTED INFORMATION. Notwithstanding any
provision to the contrary, "Due Diligence Materials" shall not include, and
Seller shall have no obligation to furnish or otherwise make available to Buyer,
any of the following documents: (i) any internally or externally prepared
reports or analysis concerning the valuation or economic performance of the
Property; (ii) any information received from or concerning any other potential
purchaser of the Property; (iii) any federal or state income tax returns; (iv)
any documents, instruments or agreements evidencing, securing or relating to any
mortgage loan currently encumbering the Real Property; (v) any correspondence or
analyses regarding past, pending or proposed real property tax appeals; or (vi)
any information or documentation that is privileged or otherwise legally
protected from disclosure under applicable law.

                           6.2.4    CONFIDENTIALITY. Buyer and its
representatives shall hold in strictest confidence all data and information
obtained with respect to Seller or the Property whether obtained before or after
the execution and delivery of this Agreement, and shall not disclose the same to
others; provided, however, that it is understood and agreed that Buyer may
disclose such data and information to the employees, lenders, consultants,
accountants and attorneys of Buyer provided that such persons agree to treat
such data and information confidentially. In the event this Agreement is
terminated or Buyer fails to perform hereunder, Buyer shall promptly return to
Seller any statements, documents, schedules, exhibits and other written
information obtained from Seller in connection with this Agreement or the
transaction contemplated herein. It is understood and agreed that, with respect
to any provision of this Agreement which refers to the termination of this
Agreement and the

                                       5
<PAGE>

return of the Deposit to Buyer, Twenty-Five Thousand Dollars ($25,000.00) of the
Deposit shall not be returned to Buyer unless and until Buyer has fulfilled its
obligation to return to Seller the materials described in the preceding sentence
and the Buyer's Reports in accordance with Section 6.5. The provisions of this
Section 6.2.4 shall survive Closing or any termination of this Agreement.

                  6.3      TITLE REVIEW. The period commencing as of the
Effective Date and continuing through the date which is ten (10) days following
the Effective Date shall be referred to as the "TITLE REVIEW PERIOD".

                           6.3.1    TITLE MATERIAL. Promptly following the
Effective Date, Seller will obtain and deliver to Buyer a current preliminary
title report ("TITLE REPORT") for the Real Property prepared by the Title
Company, together with a copy of the documents listed as exceptions therein.
Buyer, at its election, may obtain a survey ("SURVEY") of the Real Property
prepared by a licensed engineer which Survey shall be sufficient to provide the
basis for an ALTA owner's policy of title insurance. The Survey shall be
obtained by Buyer, if at all, prior to the expiration of the Title Review Period
and, if obtained, Buyer shall promptly deliver a copy of the Survey to Seller
and the Title Company. It is acknowledged that Buyer will not be entitled to
obtain an ALTA title insurance policy with respect to the Real Property if Buyer
elects not to timely obtain a Survey with respect to such Real Property.

                           6.3.2    REVIEW OF TITLE. Buyer shall notify Seller
in writing (the "TITLE NOTICE") prior to the expiration of the Title Review
Period which exceptions to title as shown on the Title Report and Survey, if
any, will not be accepted by Buyer. If Buyer fails to notify Seller in writing
of its disapproval of any exceptions to title by the expiration of the Title
Review Period, Buyer shall be deemed to have approved the condition of title to
the Real Property. If Buyer notifies Seller in writing that Buyer objects to any
exceptions to title, Seller shall have one (1) business day after receipt of the
Title Notice to notify Buyer (a) that Seller will remove such objectionable
exceptions from title on or before the Closing, provided that Seller may extend
the Closing for such period as shall be required to effect such cure, but not
beyond ten (10) days; or (b) that Seller elects not to cause such exceptions to
be removed. If Seller fails to timely give such notice to Buyer, the Seller
shall be deemed to have given notice to Buyer under clause (b). Seller shall
have no obligation to remove any title exceptions to which Buyer objects
provided, however, that Seller shall remove, as of the Closing, all liens
evidencing any deed of trust (and related documents) securing financing. The
procurement by Seller of a commitment for the issuance of the Buyer's Title
Policy (as defined in Section 3.2 hereof) or an endorsement thereto insuring
Buyer against any title exception which was disapproved pursuant to this Section
6.3.2 shall be deemed a cure by Seller of such disapproval. If Seller gives or
is deemed to have given Buyer notice under clause (b) above, Buyer shall have
one (1) business day from the date on which such notice to Buyer is given in
which to notify Seller that Buyer will nevertheless proceed with the purchase
and take title to the Property subject to such exceptions, or that Buyer will
terminate this Agreement. If Buyer fails to timely give such notice, Buyer will
be deemed to have elected to proceed with the purchase and take title to the
Property subject to such exceptions. If this Agreement is terminated pursuant to
the foregoing provisions of this Section 6.3.2, then neither party shall have
any further rights or obligations hereunder (except with respect to those
matters expressly stated to survive such termination), the Deposit shall be
returned to Buyer and each party shall bear its own costs incurred hereunder.

                           6.3.3    SUBSEQUENT TITLE DEFECTS. Buyer may, at or
prior to Closing, notify Seller in writing (the "SUBSEQUENT TITLE DEFECTS
NOTICE") of any objection(s) to title exceptions (a)

                                       6
<PAGE>

raised by the Title Company between the expiration of the Title Review Period
and the Closing and (b) not disclosed by the Title Company or the Survey or
otherwise known to Buyer prior to the expiration of the Title Review Period,
provided that Buyer must notify Seller of such objection(s) to title within two
(2) business days of being made aware of the existence of such exception. If
Buyer gives a Subsequent Title Defects Notice to Seller, Seller shall have two
(2) business days after receipt of the Subsequent Title Defects Notice to notify
Buyer (a) that Seller will remove such objectionable exceptions from title on or
before the Closing, provided that Seller may extend the Closing for such period
as shall be required to effect such cure, but not beyond ten (10) days; or (b)
that Seller elects not to cause such exceptions to be removed. If Seller fails
to timely give such notice to Buyer, Seller shall have been deemed to have given
notice to Buyer under clause (b). Seller shall have no obligation to remove any
title exceptions to which Buyer objects, provided however, that Seller shall
remove, as of the Closing, all liens evidencing any deed of trust (and related
documents) securing financing. The procurement by Seller of a commitment of the
Title Company for Buyer's Title Policy or an endorsement thereto insuring Buyer
against any title exception which was disapproved pursuant to this Section 6.3.3
shall be deemed a cure by Seller of such disapproval. If Seller gives or is
deemed to have given notice under clause (b) above, Buyer shall have two (2)
business days from the date on which such notice to Buyer is given in which to
notify Seller that Buyer will nevertheless proceed with the purchase and take
title to the Property subject to such exceptions or that Buyer will terminate
this Agreement. If Buyer fails to timely give such notice, Buyer shall be deemed
to have elected to proceed with the purchase and take title to the Property
subject to such exceptions. If this Agreement is terminated pursuant to the
foregoing provisions of this Section 6.3.3 then neither party shall have any
further rights or obligations hereunder (except with respect to those matters
expressly set forth to survive such termination), the Deposit shall be returned
to Buyer and each party shall bear its own costs incurred hereunder.

                  6.4      INSPECTION; RIGHT OF ENTRY. Buyer and Buyer's agents,
contractors, engineers, consultants, employees and other representatives
(collectively, "BUYER'S REPRESENTATIVES") shall have the right, during the Due
Diligence Period and subject to the terms and conditions of Section 6.6 below,
(i) to enter the Real Property to inspect the same (including the performance of
environmental audits of the Real Property in accordance with the terms of
Section 6.4.1 and 6.4.2 below), upon reasonable notice to Seller, provided that
Buyer does not unreasonably disturb any business of Seller in connection with
the Property or any tenant of the Real Property and provided that Seller shall
be afforded the opportunity to participate in such visitations and (ii) to
contact representatives of third parties who have executed Service Contracts
with Seller or Seller's representatives regarding the Real Property. Buyer shall
keep the Property free and clear of any mechanics' liens, materialmen's liens or
claims arising out of any of Buyer's activities or those of Buyer's
Representatives on or with respect to the Real Property. All entries onto the
Real Property by Buyer and all inspections and examinations thereof shall be at
Buyer's sole cost and expense, shall be done in a workmanlike manner in
accordance with all applicable codes, statutes, ordinances, rules, regulations
and laws and shall not disturb in any way the quiet occupancy or enjoyment of
any tenant or other occupant of the Real Property. Buyer shall not perform any
test or inspection or carry out any activity at the Real Property which damages
the Real Property in any way or which is physically intrusive into the
Improvements or soil of the Real Property without the prior written consent of
Seller, which Seller may withhold in its sole and absolute discretion. After
each entry onto any portion of the Real Property, Buyer, at its sole cost and
expense shall repair (which shall include replacement where necessary) any
damage to the Real Property arising from such entry. In connection with any
inspections of the Real Property, Buyer and Buyer's Representatives will carry
liability insurance adequate in Seller's reasonable judgement and, upon the
request of Seller, will

                                       7
<PAGE>

provide Seller with written evidence of same. Buyer will give Seller reasonable
prior notice of its intention to conduct any inspections or tests with respect

by the parties if final bills are not available. Seller shall not assign to
Buyer any deposits which Seller has with any utility companies servicing the
Property. Buyer shall arrange with such companies to have accounts open in

elapsed as of 12:01 a.m. on the Closing Date provided that the cash portion of
the Purchase Price is received by Seller's depository bank in time to credit to
Seller's account on the Closing Date. If the cash portion of the Purchase Price
is not so received by Seller's depository bank on the Closing Date, then the day

of opinion or strategy with respect to the defense of such action or the
assertion of counterclaims to be brought with respect thereto, Buyer's counsel

representations or warranties of Buyer set forth in Section 11.3 of this
Agreement.

                  12.4     DEFENSE OF CLAIMS AGAINST SELLER. With respect to any
claim for which Seller has requested indemnification under Section 12.3, Buyer
shall be entitled to assume the defense of any related litigation, arbitration
or other proceeding, provided that Seller may at its election and expense,

strategy, defense or counterclaim to be employed. At Buyer's reasonable request,
Seller will cooperate with Buyer in the preparation of any defense for any such
claim and Buyer will reimburse Seller for any reasonable expenses incurred in

                                       18
<PAGE>

to assume the defense of any such matter, and such matter is defended by Seller,

         13.      CASUALTY OR CONDEMNATION.

                  13.1     CASUALTY. Prior to the Closing, and notwithstanding
the pendency of this Agreement, the entire risk of loss or damage by earthquake,
flood, landslide, fire or other casualty shall be borne and assumed by Seller,
except as otherwise provided in this Section 13.1. If, prior to the Closing, any
part of the Real Property is damaged or destroyed by earthquake, flood,
landslide, fire or other casualty, Seller shall immediately notify Buyer of such
fact. If such damage or destruction is "material", Buyer shall have the option
to terminate this Agreement upon notice to Seller given not later than ten (10)
days after receipt of Seller's notice. For purposes of this Section 13.1,
"material" shall be deemed to be any damage or destruction (i) where the costs
of repair or replacement is estimated to be One Hundred Thousand Dollars
($100,000.00), or more, or (ii) which Seller reasonably estimates shall take
more than ninety (90) days to repair. If Buyer does not exercise this option to
terminate this Agreement, or the casualty is not material, neither party shall
have the right to terminate this Agreement, but Seller shall assign and turn
over to Buyer, and Buyer shall be entitled to receive and keep all insurance
proceeds payable to it with respect to such destruction (but not in excess of
the Purchase Price) and the parties shall proceed to the Closing pursuant to the
terms hereof without modification of the terms of this Agreement and without any
reduction in the Purchase Price. If Buyer does not elect to terminate this
Agreement by reason of any casualty, Buyer shall have the right to participate
in any adjustment in the insurance claim. If Buyer does terminate this Agreement
pursuant to this Section 13.1, this Agreement shall terminate, all rights and
obligations hereunder of each party shall be at an end (except those matters
which are specifically stated in this Agreement to survive the termination) and
the Title Company is hereby instructed to return promptly to the party which
placed such items into Escrow all funds (including the Deposit which is to be
promptly returned to Buyer) and documents which are held by the Title Company on
the date of termination.

                  13.2     CONDEMNATION. In the event that all or any
substantial portion of the Real Property shall be taken in condemnation or under
the right of eminent domain after the Effective Date and before the Closing,
Buyer may, at its option either (a) terminate this Agreement by written notice
thereof to Seller and receive an immediate refund of the Deposit, together with
any interest earned thereon, or (b) proceed to close the transaction
contemplated herein pursuant to the terms hereof in which event Seller shall
assign and turn over to Buyer, and Buyer shall be entitled to receive and keep
all awards for the taking by eminent domain which accrue to Seller and there
shall be no reduction in the Purchase Price. For purposes of this provision, a
"substantial portion" of the Real Property shall mean (i) any material portion
of the Real Property is taken; (ii) the access to the Real Property or available
parking area therefor is materially reduced or restricted; or (iii) any of the
rentable square footage of the Improvements is taken. In the event that a
portion of the Real Property less than a substantial portion is taken, or Buyer
elects not to terminate this Agreement, Buyer shall proceed to close the
transaction contemplated herein and there shall be no reduction in the Purchase
Price and Seller shall assign and turn over to Buyer and Buyer shall be entitled
to receive and keep all awards for the taking by eminent domain which accrue to
Seller.

                  16.1     NO RELIANCE ON DOCUMENTS. Except as expressly stated
herein, Seller makes no representation or warranty as to the truth, accuracy or
completeness of any materials, data or information delivered by Seller or its

         BUYER REPRESENTS TO SELLER THAT BUYER HAS CONDUCTED, OR WILL CONDUCT
PRIOR TO CLOSING, SUCH INVESTIGATIONS OF THE PROPERTY, INCLUDING BUT NOT LIMITED
TO, THE PHYSICAL AND ENVIRONMENTAL CONDITIONS THEREOF, AS BUYER DEEMS NECESSARY
OR DESIRABLE TO SATISFY ITSELF AS TO THE CONDITION OF THE PROPERTY AND THE
EXISTENCE OR NONEXISTENCE OR CURATIVE ACTION TO BE TAKEN WITH RESPECT TO ANY
HAZARDOUS OR TOXIC SUBSTANCES ON OR DISCHARGED FROM THE PROPERTY, AND WILL RELY
SOLELY UPON SAME AND NOT UPON ANY INFORMATION PROVIDED BY OR ON BEHALF OF SELLER
OR ITS AGENTS OR EMPLOYEES WITH RESPECT THERETO, OTHER THAN SUCH
REPRESENTATIONS, WARRANTIES AND COVENANTS OF SELLER AS ARE EXPRESSLY SET FORTH
IN THIS AGREEMENT. UPON CLOSING, BUYER SHALL ASSUME THE RISK THAT ADVERSE

         RELEASE, WHICH IF KNOWN BY HIM MUST HAVE MATERIALLY AFFECTED HIS
         SETTLEMENT WITH THE DEBTOR."

                  16.3     MATERIAL CHANGE. Seller shall promptly notify Buyer
of any change in any condition with respect to the Property or any event or
circumstance which makes any representation or warranty of Seller as set forth
in Section 11.2 of this Agreement materially untrue or misleading or any
covenant of Seller under this Agreement incapable of being performed. In no
event shall Seller be liable to Buyer for, or be deemed to be in default
pursuant to this Agreement by reason of any inaccuracy of a representation or
warranty which results from any change that (i) occurs between the Effective
Date and the Closing Date; and (ii) is expressly permitted under the terms of
this

                                       22
<PAGE>

Agreement or is beyond the reasonable control of Seller to prevent; provided,
however, that the occurrence of a material change which is not permitted
hereunder shall constitute the non-fulfillment of the condition set forth in
Section 7.2.2 hereof. If, in spite of such nonfulfillment of the conditions set
forth in such Section 7.2.2 the Closing occurs, Seller's representations and
warranties set forth in this Agreement shall be deemed to have been modified by
all statements made in any notice or notices of modification as given by Seller
to Buyer pursuant to this Section 16.3 prior to the Closing.

                  16.4     SURVIVAL OF SELLER'S REPRESENTATIONS AND WARRANTIES.
The representations and warranties of Seller set forth in Section 11.2 hereof
(as such may have been updated as of the Closing in accordance with Section
16.3) in accordance with the terms of this Agreement, shall survive Closing for
a period of twelve (12) months. No claim for a breach of any representation or
warranty of Seller shall be actionable or payable if the breach in question
results from or is based on a condition, state of facts or other matter which
was known to Buyer prior to Closing. Seller shall have no liability to Buyer for
a breach of any representation or warranty (a) unless the valid claims for all
such breaches collectively aggregate more than One Hundred Thousand Dollars
($100,000.00), in which event the amount of such valid claims in excess of One
Hundred Thousand Dollars ($100,000.00) shall be actionable, up to the Maximum
(as defined in this Section), and (b) unless written notice containing a
description of the specific nature of such breach shall have been given by Buyer
to Seller prior to the expiration of said twelve (12) month period and any
action shall have been commenced by Buyer against Seller within fourteen (14)
months of Closing. Buyer agrees to first seek recovery under any insurance
policies, Service Contracts and the Lease(s) prior to seeking recovery from
Seller, and Seller shall not be liable to Buyer if Buyer's remaining claim after
recovery from such insurance policies, Service Contracts and/or Lease(s) is less
than One Hundred Thousand Dollars ($100,000.00). As used herein, the term
"MAXIMUM" shall mean the total aggregate amount of Five Hundred Thousand Dollars
($500,000.00).

                  16.5     SURVIVAL OF LIMITATIONS. The provisions of this
Article 16 shall survive Closing or any termination of this Agreement.

         17.      MISCELLANEOUS.

                  17.1     TIME. Time is of the essence in the performance of
each party's obligations hereunder; however, if the final date of any period
which is set out in any provision of this Agreement falls on a Saturday, Sunday
or legal holiday under the laws of the United States or the State in which the
Property is located, then, in such event, the time of such period shall be
extended to the next day which is not a Saturday, Sunday or legal holiday.

                  17.2     ATTORNEYS' FEES. If any legal action, arbitration or
other proceeding is commenced to enforce or interpret any provision of this
Agreement, the prevailing party shall be entitled to seek an award of its
attorneys' fees and expenses. The phrase "prevailing party" shall include a
party who receives substantially the relief desired whether by dismissal,
summary judgment, judgment or otherwise.

                  17.3     NO WAIVER. No waiver by any party of the performance
or satisfaction of any covenant or condition shall be valid unless in writing
and shall not be considered to be a waiver by such party of any other covenant
or condition hereunder.

                  17.4     ENTIRE AGREEMENT. This Agreement contains the entire
agreement between the parties regarding the Property and supersedes all prior
agreements, whether written or oral, between the parties regarding the same
subject. This Agreement may only be modified in writing.

                  17.5     SURVIVAL. The provisions of this Agreement shall not
merge with the delivery of the Deed but shall, except as otherwise provided in
this Agreement, survive the Closing.

                  17.6     SUCCESSORS AND ASSIGNS. This Agreement shall be
binding upon and inure to the benefit of the heirs, executors, administrators

                  18.1     LIQUIDATED DAMAGES. FROM AND AFTER THE EXPIRATION OF
THE DUE DILIGENCE PERIOD, IN THE EVENT THE SALE OF THE PROPERTY AS CONTEMPLATED
HEREUNDER IS NOT CONSUMMATED DUE TO A DEFAULT OF BUYER, THE DEPOSIT (INCLUDING
ALL INTEREST EARNED FROM THE INVESTMENT THEREOF) SHALL BE PAID TO AND RETAINED
BY SELLER AS LIQUIDATED DAMAGES. THE PARTIES ACKNOWLEDGE THAT SELLER'S ACTUAL
DAMAGES IN THE EVENT THAT THE SALE IS NOT CONSUMMATED WOULD BE EXTREMELY
DIFFICULT OR IMPRACTICABLE TO DETERMINE. THEREFORE, BY SEPARATELY EXECUTING THIS
SECTION 18.1 BELOW, THE PARTIES ACKNOWLEDGE THAT THE NONREFUNDABLE DEPOSIT HAS
BEEN AGREED UPON, AFTER NEGOTIATION, AS THE PARTIES' REASONABLE ESTIMATE OF
SELLER'S DAMAGES AND AS SELLER'S EXCLUSIVE REMEDY AGAINST BUYER IN THE EVENT THE
CLOSING DOES NOT OCCUR AND AS SELLER'S SOLE AND EXCLUSIVE REMEDY AGAINST BUYER
ARISING FROM SUCH FAILURE OF THE SALE TO CLOSE. IN ADDITION, BUYER SHALL PAY ALL
TITLE, SURVEY AND ESCROW CANCELLATION CHARGES. NOTWITHSTANDING THE FOREGOING, IN
NO EVENT SHALL THIS SECTION 18.1 LIMIT THE DAMAGES RECOVERABLE BY EITHER PARTY
AGAINST THE OTHER PARTY DUE TO (A) THE OTHER PARTY'S OBLIGATION TO INDEMNIFY
SUCH PARTY IN ACCORDANCE WITH THIS AGREEMENT, OR (B) THIRD PARTY CLAIMS. BY
THEIR SEPARATELY EXECUTING THIS SECTION 18.1 BELOW, BUYER AND SELLER ACKNOWLEDGE
THAT THEY HAVE READ AND UNDERSTOOD THE ABOVE PROVISION COVERING LIQUIDATED
DAMAGES, AND THAT EACH PARTY WAS REPRESENTED BY COUNSEL WHO EXPLAINED THE
CONSEQUENCES OF THIS LIQUIDATED DAMAGES PROVISION AT THE TIME THIS AGREEMENT WAS
EXECUTED.

                  18.2     DEFAULT BY SELLER. In the event the sale of the
Property as contemplated hereunder is not consummated due to Seller's default
hereunder, Buyer shall be entitled, as its sole remedy, either (a) to receive
the return of the Deposit, which return shall operate to terminate this
Agreement and release Seller from any and all liability hereunder, or (b) to
enforce specific performance of Seller's obligation to convey the Property to
Buyer in accordance with the terms of this Agreement, it being understood and
agreed that the remedy of specific performance shall not be available to enforce
any other obligation of Seller hereunder. Buyer expressly waives its rights to
seek damages in the event of Seller's default hereunder. Buyer shall be deemed
to have elected to terminate this Agreement and receive back the Deposit if
Buyer fails to file suit for specific performance against Seller in a court
having jurisdiction in the county and state in which the Real Property is
located, on or before thirty (30) days following the date upon which Closing was
to have occurred.
