         SECTION 2.4 Buyer's Review and Transferors' Disclaimer.

                 (a) Buyer acknowledges that Transferors have afforded Buyer and
its agents and representatives an opportunity to review all of the Disclosure
Materials prior to the date of this Agreement and, subject to the express terms
of this Agreement, that Buyer has completed such review to its satisfaction.
Buyer has assumed fully the risk that Buyer has failed completely and adequately
to review and consider any or all of such materials. But for Buyers' expression
of satisfaction with the content of the Disclosure Materials, Buyer would not
have entered into this Agreement; but for Buyer's expression of such
satisfaction and assumption of any risk as to the character of its review and
consideration of the Disclosure Materials, Transferors would not have entered
into this Agreement. Nevertheless, during the Confirmation Period, Buyer shall
be permitted to make a further review of information relating solely to the
matters described on Exhibit N attached hereto (the "Investigation Matters") to
determine whether any Material Adverse Matters Amounts exist with respect to the
Properties and the extent of any such Material Adverse Matters Amount. Following
the Confirmation Period, Buyer shall have no further right of inspection and
review with respect to the Properties except solely for the purpose of assisting
Buyer in its management transition as provided in Sections 4.2(m) and (o) and
Section 6.10. The rights and obligations of the parties arising out of Buyer's
determination and assertion prior to





                                       5
<PAGE>   9

the close of the Confirmation Period that such Material Adverse Matters Amounts
do exist shall be limited and solely governed by the provisions of Section 2.5
below and Exhibit N attached hereto.

                 (b) Buyer's exercise of the rights of review and confirmation
set forth in subsection (a) shall be subject to the following limitations: (i)
any entry onto any Property by Buyer, its agents or representatives, shall be
during normal business hours, following not less than 24 hours' prior notice to
Transferors and, at Transferors' discretion, accompanied by a representative of
Transferors; (ii) Buyer shall not conduct any drilling, test borings or other
disturbance of any Property for review of soils, compaction, environmental,
structural or other conditions without Transferors' prior written consent (which
may be withheld in Transferor's sole and absolute discretion); (iii) any
discussions or interviews with any third party, any partner of any Transferors,
any tenants of a Property or their respective personnel, at Transferors'
election, shall be conducted in the presence of Transferors or their
representatives; (iv) any discussions or interviews with employees at any
Property shall be limited to designated senior employees and, at Transferors'
election, shall be conducted in the presence of Transferors or their
representatives; (v) Buyer shall exercise reasonable diligence not to disturb
the use or occupancy or the conduct of business at any Property; (vi) prior to
any entry upon the Property by Buyer or any of its agents, representatives or
consultants for the purpose of conducting any inspections, investigations or
tests, Buyer shall deliver to Transferors a certificate of insurance evidencing
that Buyer carries a liability insurance policy in an amount not less than
$5,000,000, which liability insurance policy names each Transferors as an
additional insured; and (vii) Buyer shall indemnify, defend and hold Transferors
harmless from all loss, cost, and expense relating to personal injury or
property damage resulting from any entry or inspections performed by Buyer, its
agents or representatives. Subject to the provisions of this Agreement,
Transferors shall at all times use all reasonable efforts (but at no material
cost to Transferors) to provide Buyer with access or information that Buyer may
reasonably request concerning the Properties, but Transferors shall bear no
liability if Transferors are not able to afford Buyer such access or information
despite such reasonable efforts.

                 (c) Buyer acknowledges (i) that Buyer has entered into this
Agreement with the intention of making and relying upon its own investigation of
the physical, environmental, economic and legal condition of the Properties,
(ii) that, other than those specifically set forth in Article IV below or in any
document to be delivered pursuant to Section 6.1 below, Transferors are not
making and have not at any time made any warranty or representation of any kind,
expressed or implied, with respect to the Properties, including, without
limitation, warranties or representations as to habitability, merchantability,
fitness for a particular purpose, title (other than Transferors' limited
warranty of title set forth in the Deeds), zoning, tax consequences, latent or
patent physical or environmental condition, utilities, operating history or
projections, valuation, projections, compliance with law or the truth, accuracy
or completeness of the Disclosure Materials, (iii) that other than those
specifically set forth in Article IV below or in any document to be delivered
pursuant to Section 6.1 below, Buyer is not relying upon and is not entitled to
rely upon any representations and warranties made by Transferors or anyone
acting or claiming to act on any of Transferors' behalf, (iv) that the
Disclosure Materials include soils, environmental and physical reports prepared
for Transferors by third parties as to which Buyer has no right of reliance,
Buyer has conducted an independent evaluation and Transferors have made no
representation whatsoever as to accuracy, completeness or adequacy (provided,





                                       6
<PAGE>   10

however, that nothing herein shall be deemed to limit Buyer's right to seek to
obtain from the third parties which prepared such reports the right to rely on
such reports at no cost to Transferors), and (v) that the Disclosure Materials
include economic projections which reflect assumptions as to future market
status and future Property income and expense with respect to the Properties
which are inherently uncertain and as to which Transferors have not made any
guaranty or representation whatsoever. Buyer further acknowledges that it has
not received from Transferors any accounting, tax, legal, architectural,
engineering, property management or other advice with respect to this
transaction and is relying solely upon the advice of its own accounting, tax,
legal, architectural, engineering, property management and other advisors.
Except as provided in the representations and warranties of Transferors set
forth in Article IV below and except as otherwise expressly set forth in this
Agreement or in any document to be delivered pursuant to Section 6.1 below,
based upon the order of Buyer's familiarity with and due diligence relating to
the Properties and pertinent knowledge as to the markets in which the Properties
are situated and in direct consideration of Transferors' decision to sell or
exchange the Properties to Buyer for the Price and not to pursue available
disposition alternatives, Buyer shall purchase the Properties in an "as is,
where is and with all faults" condition on the Closing Date and assumes fully
the risk that adverse latent or patent physical, environmental, economic or
legal conditions may not have been revealed by its investigations. Transferors
and Buyer acknowledge that the compensation to be paid to Transferors for the
Properties has taken into account that the Property is being sold or exchanged
subject to the provisions of this Section 2.4. Transferors and Buyer agree that
the provisions of this Section 2.4 shall survive closing.

                 (d) Consistent with the foregoing and subject solely to the
express covenants and indemnities set forth in this Agreement and the
representations set forth in Section 4.1 or in any document to be delivered
pursuant to Section 6.1 below (as such covenants, indemnities and
representations are limited pursuant to Section 4.4 hereof), effective as of the
Closing Date, Buyer, for itself and its agents, affiliates, successors and
assigns, hereby releases and forever discharges Transferors, their respective
members, beneficial owners, agents, affiliates, successors and assigns
(collectively, the "Releasees") from any and all rights, claims and demands at
law or in equity, whether known or unknown at the time of this agreement, which
Buyer has or may have in the future, arising out of the physical, environmental,
economic or legal condition of the Properties, including, without limitation,
all claims in tort or contract and any claim for indemnification or contribution
arising under the Comprehensive Environmental Response, Compensation, and
Liability Act (42 U.S.C. Section 9601, et. seq.) or any similar federal, state
or local statute, rule or ordinance relating to liability of property owners for
environmental matters. Without limiting the foregoing, Buyer, upon closing,
shall be deemed to have waived, relinquished and released Transferors and all
other Releasees from and against any and all matters arising out of latent or
patent defects or physical conditions, violations of applicable laws and any and
all other acts, omissions, events, circumstances or matters affecting the
Properties, except for breach of the express covenants and indemnities set forth
in this Agreement and the representations and warranties set forth in Section
4.1 or in any document to be delivered pursuant to Section 6.1 (as such
covenants, indemnities and representations are limited pursuant to Section 4.4
hereof). For the foregoing purposes, Buyer hereby specifically waives the
provisions of Section 1542 of the California Civil Code and any similar law of
any other state, territory or jurisdiction. Section 1542 provides:





                                       7
<PAGE>   11

         A general release does not extend to claims which the 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 hereby specifically acknowledges that Buyer has carefully reviewed this
subsection and discussed its import with legal counsel and that the provisions
of this subsection are a material part of this Agreement.


                                 _______________
                                      Buyer

in this Agreement and the representations of Transferors set forth in Section
4.1 or in any document to be delivered pursuant to Section 6.1 (as such
covenants, indemnities and representations are limited pursuant to Section 4.4
hereof), Buyer shall indemnify, defend and hold Transferors harmless from and
against any and all losses, damages, causes of action, costs and expenses
(including without limitation, reasonable attorneys' fees and costs), claims and
liabilities in connection with or relating directly or indirectly to the
Properties to the extent arising out of or resulting from acts or omissions
occurring from and after the Closing Date. Transferors shall indemnify, defend
and hold Buyer harmless from and against any and all losses, damages, causes of
action, costs and expenses (including, without limitation, reasonable attorneys'
fees and costs), claims and liabilities in connection with claims brought by
third parties unaffiliated to Buyer (i) for physical injury to persons or
physical damage to property to the extent such injury or damage occurred on the
Properties and arose out of or resulted from acts or omissions of Transferors
that took place prior to the Closing Date, (ii) with respect to acts or
omissions of Transferors that took place prior to the Closing Date and that are
actually insured under an insurance policy carried by Transferors (and then only
to the extent of the proceeds actually paid under such policy, Transferors
agreeing to use commercially reasonable efforts to realize such insurance
proceeds) and (iii) with respect to each of the matters which are listed on
Exhibit W attached hereto as such list may be amended from time to time during
the Contract Period by Transferors (and provided to Buyer) to reflect new
litigation filed against Transferors during the Contract Period (the foregoing
items (i), (ii) and (iii) being collectively referred to as "Claims"); provided
that Transferors' indemnity contained in this Section 2.4(e) shall not apply to
any Claims relating to or arising out of or in connection with the environmental
condition of the Properties whether or not such Claim may be covered by
Transferors' environmental insurance policies.

         SECTION 2.5 Material Adverse Matters Amounts.

                 (a) On or prior to the close of the Confirmation Period, Buyer
shall deliver to Transferors the Confirmation Letter in the form attached as
Exhibit B to this Agreement confirming Buyer's satisfaction as to the absence of
any Material Adverse Matters Amounts other than as specified in the Confirmation
Letter and waiving any further right or need to conduct further review or
investigation for such purposes. Buyer's failure to deliver to Transferors on or
prior to the close of the Confirmation Period an executed Confirmation Letter in
the form attached as Exhibit B, without modification or qualification in any
manner whatsoever (whether material or immaterial) -- excepting an enumeration
and explanation of





                                       8
<PAGE>   12

identified Material Adverse Matters Amounts, shall be deemed conclusively as
Buyer's confirmation of the absence of any Material Adverse Matters Amounts.

                 (b) If the Confirmation Letter identifies any Material Adverse
Matters Amounts, the Confirmation Letter shall set forth: (i) the identity of
any Properties as to which Buyer has identified any Material Adverse Matters
Amounts, (ii) the nature of the Investigation Matter for each affected Property
which resulted in such Material Adverse Matters Amounts and (iii) reasonably
detailed evidence of the existence of such Material Adverse Matters Amount and
Buyer's rationale for and calculation of the Material Adverse Matters Amounts
set forth.

                 (c) If the Confirmation Letter does so identify Material
Adverse Matters Amounts, then, for a period ending five (5) business days
following the close of the Confirmation Period, Buyer and Transferors shall
negotiate in good faith (but otherwise as a matter within each party's sole
discretion) to determine whether the parties can reach a mutually acceptable
reduction in the Price. The parties further acknowledge that neither
participation in nor any statements made in the course of such discussions shall
represent or be interpreted as an admission or agreement as to the existence,
character or measure of any Material Adverse Matters Amount.

                 (d) In any event, if the parties are not able to reach and
execute a written agreement evidencing a mutually satisfactory Price adjustment
within such five (5) business day negotiation period, Transferors shall provide
Buyer with written notice (the "Election Notice") within an additional period of
three (3) business days informing Buyer that Transferors, in Transferors' sole
discretion: (i) dispute the existence or measure of Material Adverse Matters
Amounts as to Properties identified in the Election Notice, (ii) accept Buyer's
calculation of the Material Adverse Matters Amounts, in which case the Price
shall be reduced by the Material Adverse Matters Amount set forth in Buyer's
calculation, or (iii) withdraw Properties identified in the Election Notice from
the sale or exchange to Buyer; provided, however, that Transferors shall not be
permitted to withdraw any Property unless the Material Adverse Matters Amount
claimed by Buyer exceeds $200,000 with respect to such Property and exceeds
$900,000 with respect to all of the Properties (in which event Transferors, in
Transferors' discretion, may withdraw such Properties as to which Material
Adverse Matters Amounts are claimed until the claimed Material Adverse Matters
Amounts for the remaining Properties is less than or equal to $900,000). Any
Property identified as the subject of dispute under clause (i) above shall be
referred to as a "Deferred Property." Any Property withdrawn under clause (iii)
above shall be referred to as a "Deleted Property."

                 (e) If Transferors have elected to dispute the calculation of
any Material Adverse Matters Amounts under subsection (d)(i) above, such dispute
shall be submitted promptly to arbitration pursuant to Section 7.5 below. Buyer
and Transferors, respectively, shall remain fully obligated to purchase and sell
or exchange, as applicable, both the Deferred Properties and all other
Properties (excepting any Deleted Properties) on the terms and conditions set
forth in this Agreement, provided that (i) the Price payable on the Closing Date
applicable to all other Properties shall be reduced by the Allocated Price of
the Deferred Properties, (ii) the Closing Date with respect to the Deferred
Properties shall be deferred to that date ten (10) business days following the
issuance of a final decision in arbitration, (iii) an amount equal to five
percent (5%) of the Allocated Price for each Deferred Property shall be





                                       9
<PAGE>   13

retained by Title Company as a continuing Deposit subject to disposition in
accordance with Section 5.1 below as to such Deferred Property and (iv) the
Allocated Price with respect to each Deferred Property shall be subject to any
reduction determined in arbitration.

                 (f) Subject to the provisions of Section 2.8, if a Property is
designated as a Deleted Property, Buyer and Transferors, respectively, shall
have no further obligation to purchase or sell or exchange, as applicable, the
Deleted Properties, shall remain obligated to purchase or sell or exchange, as
applicable, all other Properties and the Price payable on the Closing Date
applicable to all other Properties shall be reduced by the Allocated Prices of
the Deleted Properties.

         SECTION 2.6 Title Exceptions.

                 (a) Buyer acknowledges that prior to the date hereof,
Transferors have provided to Buyer access to copies of the Title Policies, as
well as copies of the exception documents referred to in the Title Policies and
copies of the Surveys of the Properties, to the extent such exceptions are in
Transferors' immediate possession. Buyer also acknowledges that Transferors have
requested Title Company to deliver to Buyer updated title reports to the Title
Policies, as well as copies of any exception documents relating to exceptions
that are reflected in such updates that have not otherwise been provided to
Buyer prior to the date hereof; provided that Transferors shall have no
liability hereunder if Buyer is unable to obtain copies of any such documents
and Buyer shall have no rights hereunder with respect thereto. Buyer may
continue to secure during the Confirmation Period any additional title or survey
updates desired by Buyer (and will use reasonable efforts to provide the copies
of such updates to Transferors promptly after receipt of same by Buyer). As used
herein, the term "Additional Exceptions" shall mean (i) any title exceptions or
survey exceptions or qualifications identified by Title Company that are not
within the definition of Permitted Exceptions, (ii) the items listed on Exhibit
G-2 to the extent they materially and adversely affect the use, occupancy or
value of a Property, provided that such items shall not be deemed to materially
and adversely affect the use, occupancy and value of a Property to the extent
Buyer has approved (or is deemed to have approved) exceptions on such Property
or other Properties which are substantially similar in all material respects,
(iii) matters shown on surveys described in the Exhibit G Title Policies (as
defined in Exhibit G) or, if such surveys cannot be located or otherwise
obtained, on new surveys obtained by Buyer, for the Properties identified on
Exhibit G-2 which were not shown on the surveys for such Properties delivered or
made available to Buyer, if applicable, and which materially and adversely
affect the use, occupancy or value of a Property, provided that such items shall
not be deemed to materially and adversely affect the use, occupancy and value of
a Property to the extent Buyer has approved (or is deemed to have approved) such
matters on such Property or other Properties which are substantially similar in
all material respects, and (iv) with respect to any Property as to which the
Title Company will not agree at least ten (10) business days prior to the end of
the Confirmation Period to issue a survey endorsement referring to the same
survey as is referenced in Transferors' most recent Exhibit G Title Policy (for
such Property), any variance established by Buyer from the legal descriptions
insured in Transferors' most recent Exhibit G Title Policies to the surveys
described in such Title Policies (other than variances actually known to Buyer
as of the date hereof). Buyer, in any event, shall endeavor in good faith (but
at no out-of-pocket cost to Buyer) to cause the Title Company to delete or
insure over any Additional Exceptions to Buyer's reasonable satisfaction prior
to Buyer's expression of such matters in an





                                       10
<PAGE>   14

Additional Title Exception Notice (as described below). Buyer shall have the
right to request that the Title Company provide at Buyer's sole cost and expense
any reinsurance or endorsements Buyer shall reasonably request with respect to
Permitted Exceptions, Additional Exceptions or otherwise, provided that the
issuance of such reinsurance or endorsements shall not be a condition to or
delay the closing except as otherwise provided in this Agreement.

                 (b) Buyer shall have the right to deliver a notice to
Transferors identifying any Additional Exceptions (the "Additional Title
Exception Notice") by the earlier of (i) five (5) business days after Scott
Verges becomes aware of the matter constituting an Additional Exception or (ii)
the close of the Confirmation Period. Buyer's failure to deliver any such notice
in timely fashion shall be deemed an approval of any such Additional Exceptions.
Buyer shall have no right to deliver an Additional Title Exception Notice
following the close of the Confirmation Period. If Buyer delivers an Additional
Title Exception Notice within such period, Buyer and Transferors shall promptly
attempt to agree upon the method or cost to cure or remove such Additional
Exception or, if not susceptible to cure or removal, an appropriate reduction in
the Allocated Price for the affected Property. If Transferors and Buyer are
unable to agree upon a resolution within five (5) business days following
Transferors' receipt of an Additional Title Exception Notice, Transferors shall
elect, at its option and by written notice given not later than the date of
Transferors' delivery of an Election Notice under Section 2.5(d) above, (i) to
terminate this Agreement with respect to the affected Property, in which event
such Property shall be treated as a Deleted Property or (ii) to submit the
existence of the Additional Exception, the character of a satisfactory cure or
the measure of appropriate price reduction to arbitration in accordance with the
terms of Section 7.5, in which case the Property shall be treated as a Deferred
Property. Notwithstanding the foregoing, Buyer shall not have the right to
object to any Additional Exception if Title Company is willing to affirmatively
insure or endorse over such Additional Exception at Transferors' expense, and
the Title Company is acting in a commercially reasonable manner in providing
such affirmative insurance or endorsement and Buyer reasonably approves the form
and substance of such affirmative insurance or endorsement.

                 (c) "Permitted Exceptions" shall include and refer to the title
exceptions set forth in Exhibit G attached hereto. Notwithstanding the
foregoing, Transferors shall remove or cause the Title Company to remove or,
except with respect to Deed of Trust Liens (as herein defined), endorse over by
endorsement reasonably satisfactory to Buyer, at Transferors' sole cost and
expense, on or prior to the Closing Date and there shall not be treated as
Permitted Exceptions: (i) any liens of any mortgages or deeds of trust securing
indebtedness of Transferors or its affiliates (collectively, "Deed of Trust
Liens") and any other liens for monetary obligations (including mechanic's
liens, but excluding (A) mechanic's liens filed by contractors or any other
parties which are working for tenants under Leases or for Transferors where the
obligation to pay such contractors or other parties is directly or indirectly an
obligation of such tenants (but only to the extent (x) such obligation is not
subject to reimbursement or payment by Transferors or its affiliates and (y)
such tenant has neither filed for protection under applicable bankruptcy laws
nor abandoned its premises) or which arise in connection with work as to which
Buyer is to receive a credit at the closing (but only to the extent of such
credit) or has agreed to assume the obligation which is the subject of such
lien, and (B) any other liens which, in the aggregate, exceed Thirty-Five
Thousand Dollars ($35,000) for a particular Property, which arise following the
date of Buyer's execution and delivery of this Agreement and which were not
created by or





                                       11
<PAGE>   15

acquiesced in by Transferors, any affiliate of Transferors, or any partner,
member, officer, director, employee, agent or representative of either such
party) that are not assumed by Buyer (for such purposes, all assessments
collected with ad valorem real estate taxes and which are paid in installments
and are not delinquent as of the Closing Date shall be assumed by Buyer (subject
to the provisions of Section 6.3) and represent Permitted Exceptions); provided,
however, that with respect to any liens identified in clause (B) above, (1)
Transferors shall have the right, in Transferors' sole discretion, to (x) remove
or cause the Title Company to remove or endorse over by endorsement reasonably
satisfactory to Buyer, such lien at Transferors' sole cost and expense on or
prior to the Closing Date, or (y) terminate this Agreement with respect to the
affected property in which event such Property shall be treated as a Deleted
Property, and (2) such liens shall not be Permitted Exceptions unless consented
to by Buyer; and (ii) any title matters created in violation of Transferors'
covenant set forth in Section 4.2(e) below.

                 (d) Transferors shall have no obligation to execute any
affidavits or indemnifications in connection with the issuance of Buyer's title
insurance excepting only the affidavit attached hereto as Exhibit K and such
other customary affidavits as to authority, the rights of tenants in occupancy,
the status of mechanics' liens and other affidavits or indemnifications
reasonably necessary to address matters of title which Transferors are obligated
to remove or cure pursuant to this Section 2.6.

         SECTION 2.7 Joint Venture Interests. Buyer acknowledges that the
Properties identified on Exhibit M attached hereto are owned by entities (each a
"Joint Venture") in which a Transferor and an unrelated third party (each, a
"Third Party" and collectively, the "Third Parties") own the beneficial
interests. If the consent or waiver of applicable Third Parties is not required
for a Transferor to sell or exchange a Property owned by a Joint Venture, then
Transferors shall cause the Property to be sold or exchanged by such Joint
Venture to Buyer. With respect to each Joint Venture where the consent or waiver
of a Third Party is required, Transferors shall, at Transferors' election made
in Transferors' sole discretion, attempt to either (i) obtain the consent of the
applicable Third Party to cause the Joint Venture to sell or exchange the
applicable Property to Buyer, or (ii) acquire the Third Party's interest in the
Joint Venture prior to or concurrent with the closing hereunder, to the extent
such purchase is permitted under the terms of the applicable Joint Venture's
operative agreement (or consented to by the Third Party) and thereafter cause
the Joint Venture to sell or exchange the applicable Property to Buyer.
Transferors shall not be required to expend any amounts to obtain the consent of
any Third Party pursuant to clause (i), but Transferors shall be required to
expend up to (but not more than) the net amount of the applicable Third Party's
proportionate share of the Allocated Price of the applicable Property based on
such Third Party's interest in the Joint Venture in order to acquire such Third
Party's interest pursuant to clause (ii) above. If Transferors are unable to
obtain a required consent or waiver from a Third Party to a sale of the Property
or acquire the Third Party's interest in such Joint Venture (after agreeing to
expend the amount set forth above), then this Agreement shall be terminated with
respect to the affected Property, in which event such Property shall be treated
as a Deleted Property.

         SECTION 2.8 Reinstatement Right. Notwithstanding anything to the
contrary contained in this Agreement, if Transferors elect to treat a Property
as a Deleted Property under Sections 2.5, 2.6 or 4.4 of this Agreement, Buyer
shall have the right, by providing Transferors with written notice given within
three (3) business days after receipt of Transferors' notice





                                       12
<PAGE>   16

designating a Property as a Deleted Property, to cause such Property to no
longer be treated as a Deleted Property and to purchase such Property in
accordance with this Agreement, in which event the specific condition giving
rise to Transferors' treatment of such Property as a Deleted Property shall be
deemed waived by Buyer and Buyer shall not receive any adjustment to the
Allocated Price for such Property or have any right to deliver a Claim Notice as
a result of such condition.

                              CONDITIONS PRECEDENT

         SECTION 3.1 Conditions.

                 (a) Notwithstanding anything in this Agreement to the contrary,
Buyer's obligation to purchase a particular Property shall be subject to and
contingent upon the satisfaction or waiver of the following conditions precedent
with respect to such Property:

                     (i) The willingness, upon the sole condition of the payment
of any regularly scheduled premium, of the Title Company (or another title
insurance company reasonably satisfactory to Buyer) to issue Owner's Policies of
Title Insurance in the form of the Title Policy issued to the applicable
Transferor with respect to each Property in connection with the initial public
offering of the stock of the Company (as herein defined) ("IPO") or, if no Title
Policy was issued for a Property in connection with the IPO, then the Title
Policy issued upon the acquisition of the Property by the applicable Transferor
(or the party that contributed such Property to the Transferor at the IPO (a
"Contributor") (or such other form(s) as may be reasonably satisfactory to
Buyer)), and with all of the endorsements issued in any Title Policy issued by
the Title Company for a particular Property insuring Buyer (or Buyer's permitted
assignee or nominee) that title to the applicable Real Property is vested of
record in Buyer (or Buyer's permitted assignee or nominee) on the Closing Date
subject only to the printed conditions and exceptions of such policies (but
deleting (by endorsement or otherwise), where permitted under applicable laws or
regulations and at Buyer's expense, any co-insurance, creditors rights and
so-called "standard" exceptions) and the Permitted Exceptions applicable to such
Real Property. Transferors will cooperate and use reasonable efforts (but at no
out-of-pocket cost to Transferors) to assist Buyer in obtaining all endorsements
contained in the Title Policies (whether issued in connection with the IPO or an
acquisition). Without limiting the foregoing, if the Title Company (and, to the
extent applicable, a different title insurance company if one other than the
Title Company previously issued any such endorsement) refuses to issue such
endorsement to Buyer at closing with respect to a matter insured against under
the Title Policies, upon request of Buyer, Transferors will assert a claim
against such insurer at Buyer's expense and direction with the goal of enabling
Buyer to obtain such endorsement from such title company. Nothing contained in
the second, third, or fourth sentence of this Section 3.1(a)(i) shall be
construed as expanding the provisions of the first sentence of this Section
3.1(a)(i) or Section 2.6 or be considered a condition to Buyer's obligation to
purchase any of the Properties and Transferors shall have no liability
whatsoever if they are unable to cause a title company to issue any such
endorsement;





                                       13
<PAGE>   17

                     (ii) With respect to a particular Property, such Property
has not been designated a Deleted Property pursuant to this Agreement; and

                     (iii) Transferors' performance or tender of performance of
all material obligations under this Agreement with respect to the applicable
Property, including Transferors' covenants under Section 4.2 with respect to
such Property.

                 (b) Notwithstanding anything in this Agreement to the contrary,
Transferors' obligation to sell or exchange a particular Property or all of the
Properties, as the case may be, shall be subject to and contingent upon the
satisfaction or waiver of the following conditions precedent:

                     (i) With respect to a particular Property, such Property
has not been designated a Deleted Property pursuant to this Agreement; and

                     (ii) Buyer's performance or tender of performance of all
material obligations under this Agreement.

         SECTION 3.2 Failure or Waiver of Conditions Precedent.

                 (a) If any of the conditions set forth in Section 3.1(a)(i) or
(iii) is not fulfilled or waived by Buyer with respect to a particular Property,
Buyer may, by written notice to Transferors, terminate this Agreement with
respect to the applicable Property and such Property shall be treated as a
Deleted Property. If the condition set forth in Section 3.1(b)(ii) is not
fulfilled or waived, Transferors may, by written notice to Buyer, terminate this
Agreement, whereupon all rights and obligations hereunder of each party shall be
at an end. Either party may, at its election, at any time or times on or before
the date specified for the satisfaction of the condition, waive in writing the
benefit of any of the conditions set forth in Section 3.1(a) and 3.1(b) above.
In any event, Buyer's consent to the close of escrow with respect to a Property
pursuant to this Agreement shall waive any remaining unfulfilled conditions for
the benefit of Buyer with respect to such Property.

                 (b) Notwithstanding the foregoing, if Buyer desires to
terminate this Agreement with respect to a Property based upon a failure of the
condition set forth in Section 3.1(a)(i) or (iii) above, Transferors shall have
a period of 30 days within which to cure such failure or, if such failure cannot
reasonably be cured within 30 days, an additional reasonable time period of up
to an additional 60 days (for a total of 90 days), so long as such cure has been
commenced within such 30 days and is at all times diligently pursued. If
Transferors have not cured such failure within such cure period then Buyer may
elect to terminate this Agreement with respect to the affected Property, in
which event such Property shall be treated as a Deleted Property.


                                    ARTICLE 4
                    COVENANTS, WARRANTIES AND REPRESENTATIVES

         SECTION 4.1 Transferors' Warranties and Representations. Each of
Transferors expresses to Buyer the representations and warranties set forth
below as of the date of this





                                       14
<PAGE>   18

Agreement, provided that each of such representations and warranties shall be
deemed expressly qualified by any information set forth on the Disclosure
Materials List & Statement or contained in the Disclosure Materials, and any
information set forth on the Disclosure Materials List & Statement or contained
in the Disclosure Materials shall be deemed an exception to each and all of
Transferors' representations and warranties set forth herein.

                 (a) Each of Transferors represents and warrants with respect to
itself as follows:

                     (i) The Transferor (and Transferor's general partners, if
Transferor is a limited partnership, and each of its constituent members, if
Transferor is a limited liability company) is duly organized, validly existing
and in good standing under the laws of its jurisdiction of organization and the
Transferor is qualified to do business in each state in which Real Property
owned by such Transferor is located to the extent the failure to so qualify
would have a material and adverse effect on Transferor's performance of its
obligations under this Agreement. The Transferor has full power and lawful
authority to enter into and carry out the terms and provisions of this Agreement
and to execute and deliver all documents which are contemplated by this
Agreement, and all actions of the Transferor necessary to confer such power and
authority upon the persons executing this Agreement (and all documents which are
contemplated by this Agreement) on behalf of the Transferor have been taken;

                     (ii) Except with respect to the third party consents
expressly described in or contemplated under this Agreement or expressly
required under any agreements included in Intangible Property, including the
consent of Third Parties, if required, the Transferor's execution and delivery
of this Agreement, the consummation of the transactions contemplated hereby and
the performance of the Transferor's obligations under the instruments required
to be delivered by the Transferor at the closing, do not and will not require
the consent, approval or other authorization of, or registration, declaration or
filing with, (collectively, "Consents") any governmental authority (excepting
the recordation of closing documents contemplated in this Agreement and any
filings required under applicable state or federal securities or tax laws) or
any other person or entity, except such Consents as will be obtained on or
before closing or as to which the failure to obtain would not have a material
and adverse effect on Transferor's performance of its obligations under this
Agreement, and do not and will not result in any material violation of, or
material default under, any term or provision of any agreement, instrument,
mortgage, loan agreement or similar document to which the Transferor is a party
or by which the Transferor is bound. Subject to the foregoing, all partnership,
limited liability company, board of directors and shareholder approvals required
for Transferor to enter into this Agreement and to consummate the transactions
described in this Agreement have been obtained;

                     (iii) There is no litigation, investigation or proceeding
pending or, to the best of the Transferor's knowledge, contemplated or
threatened against the Transferor which would impair or adversely affect the
Transferor's ability to perform its obligations under this Agreement or any
other instrument or document related hereto; and

                     (iv) The Transferor is not a "foreign person" as defined in
Internal Revenue Code 1445(f)(3).





                                       15
<PAGE>   19

                 (b) Each of Transferors represents and warrants as follows with
respect to each Property owned by such Transferor:

                     (i) As of the date of this Agreement, Transferor has no
knowledge that, and has received no written notice from any governmental
authorities that eminent domain proceedings for the condemnation of any Property
or any part of a Property are pending;

                     (ii) As of the date of this Agreement, Transferor has no
knowledge that, and has received no written notice of any threatened or pending
litigation against Transferor other than routine matters covered by Transferor's
insurance or other matters which would not materially and adversely affect any
Property;

                     (iii) As of the date of this Agreement, Transferor has
received no written notice from any governmental authority that the improvements
constituting any Property are presently in material violation of any applicable
building codes where such violation has not been cured in all material respects;

                     (iv) As of the date of this Agreement, Transferor has
received no written notice from any governmental authority that any Property is
presently in material violation of any applicable zoning, land use or other law,
order, ordinance, rule or regulation affecting the Property which violation has
not been cured, that any investigation has been commenced or is contemplated
with respect to any such possible failure of compliance and Transferor has not
received written notice from any insurance company or Board of Fire Underwriters
any written notice of any defect or inadequacy in connection with a Property or
its operation where such defect or inadequacy has not been cured in all material
respects;

                     (v) There are no Contracts involving payment in excess of
$25,000 per annum with respect to any Property that will be binding upon Buyer
after the closing, other than such Contracts that are cancelable by the owner of
the Property within 30 days after written notice from such owner without penalty
or premium (other than penalties or premiums that will be paid by Transferor on
or before the closing);

                     (vi) As of the date of this Agreement, except as set forth
in the environmental reports included within the Disclosure Materials and any
reports or studies prepared by or for Buyer, Transferor has received no written
notice of the presence or release of any Hazardous Materials presently
deposited, stored, or otherwise located on, under, in or about any Property
which require reporting to any governmental authority or are otherwise not in
compliance with environmental laws, regulations and orders;

                     (vii) The Rent Rolls constituting Exhibit E to this
Agreement completely and accurately identify as to each Lease as of February 15,
1999: the expiration date of the current term of the Lease; the amount of any
security deposit held by Transferor; the current base rental payable under such
Lease and future rent escalations; the amount of additional rent (i.e., cost
recovery) currently billed to the tenant under the Lease; and the approximate
rentable area of the premises. As of February 15, 1999, each Lease identified on
the Rent Roll was, to the best of Transferor's knowledge, in full force and
effect and, to the best of Transferor's knowledge, Transferor was not in
material default thereunder. As of March 1,





                                       16
<PAGE>   20

1999, Transferor had not received written notice of any material default by
Transferor under any Leases, which default had not been cured in all material
respects, and Transferor has not delivered any default notice to a tenant under
any Lease and, to Transferor's knowledge and except as set forth in the
delinquency reports provided by Transferors to Buyer, Transferor was not aware
of any other default by a tenant under a Lease as to which default Transferor
would customarily have delivered a notice of default to such tenant but has not
done so, which defaults have not been cured in all material respects. Transferor
has delivered or made available to Buyer copies of all Leases of more than
14,000 square feet or any amendments thereto executed on or before the date of
this Agreement (other than the Leases with Old Navy and Kids R Us at Corbins
Corner);

                     (viii) As of the date of this Agreement, Transferor has
received no written notice that Transferor or any other party is in default
under any reciprocal easement agreement or declaration of covenants, conditions,
and restrictions or any other similar instrument or agreement affecting any of
the Properties (collectively, the "REAs"), which default has not been cured in
all Material respects;

                     (ix) Except with respect to rights of Third Parties under
the Joint Ventures, Transferor has not granted any option or right of first
refusal or first opportunity to acquire any fee or ground leasehold estate of
any portion of the Properties;

                     (x) As of the date of this Agreement, the Financial
Statements delivered to Buyer by Transferor are true and correct in all material
respects;

                     (xi) With respect to the matters contained in the
Disclosure Materials List & Statement and the Disclosure Materials, to
Transferor's knowledge, Transferor has not willfully and intentionally omitted
to state any material facts required to be stated therein or willfully and
intentionally made any untrue statement of a material fact, which would render
the Disclosure Materials List & Statement or the Disclosure Materials materially
misleading. Transferor has not willfully and intentionally failed to deliver or
make available to Buyer all of the following documents in Transferor's immediate
possession and has not instructed any third party not to deliver any such
documents to Buyer: (x) reports regarding the environmental condition of the
Properties or (y) reports obtained in connection with the acquisition of a
Property regarding the physical condition and legal compliance of such Property;
and

                     (xii) Transferor has taken the steps described on Exhibit P
attached hereto in an effort to cause all computer hardware and software at each
Property which is the direct responsibility of Transferor (and not the
responsibility of a tenant, vendor or other third party) and which controls
utility and other physical operating functions including, without limitation,
alarm and other security systems, irrigation systems, lighting systems, health
safety systems and similar functions (the "Owner's Computer Systems"), to at all
times hereafter provide the following functions: (a) consistently handle date
information before, during and after January 1, 2000 including, without
limitation, accepting date input, providing date output and performing
calculations on dates or portions of dates; (b) function accurately in
accordance with the specifications for such computer hardware or software and
without interruption before, during and after January 1, 2000, without any
change in operations associated with the advent of the new century; (c) respond
to two digit date input in a way that resolves any ambiguity as to





                                       17
<PAGE>   21

century in a disclosed, defined and predetermined matter; and (d) store and
provide output data information in ways that are unambiguous as to century. To
Transferor's knowledge, as of the date of this Agreement, the cost to correct
any failure of the Owner's Computer Systems to provide the foregoing functions
would not be material (provided, that no representation or warranty is made with
respect to any such failure for reasons other than the advent of the new
century).

         Subject to the provisions of Section 4.4, each of the Transferors shall
be jointly and severally liable for the breach of any representation and
warranty of a Transferor set forth in this Section 4.1.

                                    * * * * *

For the foregoing purposes, the terms "Transferors' knowledge" or "Transferor's
knowledge" or words of similar effect shall mean the current actual, subjective
knowledge of Messrs. John Diserens, Michael Coke, Blake Baird and David Fries
(collectively, the "Knowledge Persons"), in each case without independent
investigation or inquiry, but after inquiry of the current asset managers who
are employees of Transferors in its retail division. Such individuals' knowledge
shall not include information or material which may be in the possession of any
of the Transferors or the named individuals, but of which the named individuals
are not actually aware. Transferors shall have no liability for the breach of
any representations or warranties absent an arbitrated or judicial finding that
the named individuals knowingly withheld information from Buyer with respect to
the subject matter of the representation or warranty or falsified information
delivered to and relied upon by Buyer and that such action amounted to a
violation of a representation or warranty expressly set forth in this Agreement.
None of the named individuals whose sole knowledge is imputed to a Transferors
under this Section nor any party other than the Transferors affording a
representation shall bear responsibility for any breach of such representation.

         SECTION 4.2 Transferors' Covenants. Transferors hereby covenants and
agrees as follows:

                 (a) During the Contract Period, Transferors will exercise
reasonable and good faith efforts (i) to operate and maintain the Properties in
a manner consistent with current practices and (ii) to comply, where such
compliance is the obligation of Transferors (and not of a tenant or other party)
in all material respects with all material laws and regulations applicable to
the Properties;

                 (b) During the Contract Period, Transferors will not sell or
otherwise dispose of any significant items of Personal Property unless replaced
with an item of like value, quality and utility;

                 (c) During the Contract Period, Transferors shall not enter
into or modify any Contracts relating to the operation or maintenance of a
Property, except for (i) those entered into in the ordinary course of business
with parties which are not affiliates of Transferors and (A) which are
cancelable upon not more than thirty (30) days prior notice without penalty or
premium or (B) which require payments to the applicable vendor of $25,000 or
less per year and





                                       18
<PAGE>   22

which, in the aggregate for any individual Property, require payments to the
applicable vendors of $50,000 or less per year, or (ii) those otherwise approved
by Buyer, which approval shall not be unreasonably withheld and shall be deemed
given if Buyer should fail to approve or disapprove proposed Contract matters in
writing within 5 business days following Transferor's written request (which
shall include all material information necessary to allow Buyer to make an
informed decision). At Buyer's written request provided at least five (5)
business days prior to the Closing Date, Transferors shall deliver notice of
termination on the Closing Date as to any and all Contracts that Buyer desires
to terminate, provided that such termination shall be effective following any
notice or waiting period for such termination described in the Contract and that
Transferors shall not be required to bear any termination or cancellation fee or
charge that may be assessed under such Contract based upon an early termination.
Notwithstanding the foregoing, Transferors shall terminate all property
management agreements and exclusive leasing agreements applicable to the
Properties as of the Closing Date, at Transferors' expense;

                 (d) During the Contract Period, Transferors will not execute or
modify in any material fashion any Leases pertaining to premises in excess of
5,000 rentable square feet or any ground lease, other than with Buyer's prior
consent, which shall be deemed given if Buyer (in the person of Burnham Pacific
Properties, Inc.'s chief investment officer or chief operating officer) should
fail to approve or disapprove proposed lease matters in writing within 5
business days following Transferors' written request (which shall include all
material information necessary to allow Buyer to make an informed decision).
Buyer shall exercise its rights of approval of leasing matters reasonably and in
good faith. With respect to new Leases or Lease amendments pertaining to
premises of 5,000 rentable square feet or less, Transferors shall have the right
to enter into new Leases or amendments without any need to obtain Buyer's
consent, provided that (A) such new Lease or amendment is entered into on an
arm's length basis and the applicable Transferors believes in its good faith
reasonable discretion that it is entering into such new Lease or modification on
market terms (B) such new Lease or amendment does not provide for a cap on the
pass through of cost recoveries or exclude the recovery of management fees, (C)
such new Lease or amendment does not contain a material change to the assignment
provision of Transferors' standard lease form in use at the applicable Property
(the "Standard Form"), (D) with respect to a new Lease, Transferors initiated
negotiations with such tenant using the Standard Form and any changes thereto
are consistent with Transferors' standard leasing practices, and (E) Buyer is
provided with a copy of the executed Lease or modification documents within a
reasonable period after such documents are executed. Transferors shall use
reasonable efforts to continue to seek leases for the Properties in a manner
consistent with present practice;

                 (e) During the Contract Period, except with respect to actions
taken by Third Parties without the applicable Transferor's consent in connection
with Joint Venture Properties, Transferors shall not voluntarily create, consent
to or acquiesce in the creation of liens or exceptions to title without Buyer's
prior written consent, provided that Buyer shall not unreasonably withhold or
delay consent to any proposed matters affecting title necessary to maintain or
enhance the value of the pertinent Property;

                 (f) During the Contract Period, Transferors shall maintain its
currently effective policies of property insurance and rental loss insurance for
the Improvements;





                                       19
<PAGE>   23

                 (g) During the Contract Period, Transferors shall use
commercially reasonable efforts (but at no material cost to Transferors except
as may otherwise be expressly provided in this Agreement) to obtain all third
party and governmental approvals and consents necessary to consummate the
transactions contemplated hereby;

                 (h) During the Contract Period, Transferors shall maintain
their books accounts and records in a manner consistent with past practice;

                 (i) During the Contract Period, Transferors shall observe and
comply with the material terms and conditions of all Contracts, Leases, Property
licenses, and Property approvals;

                 (j) During the Contract Period, Transferors shall not knowingly
and intentionally take any action which would cause the representations and
warranties contained in Section 4.1 (other than as permitted in this Agreement)
to cease to be true and correct in all material respects as of the Closing Date
as though then made;

                 (k) During the Contract Period, Transferors shall comply in all
material respects with all existing easements, covenants, conditions,
restrictions and other encumbrances affecting any Property;

                 (l) During the Contract Period, Transferors shall reasonably
cooperate with Buyer, but at no cost to Transferors, (i) to assist Buyer in
obtaining environmental insurance coverage for the Properties (provided, that in
no event shall Buyer have the right to perform any environmental testing in
connection with obtaining such insurance) and (ii) to enable Buyer to exercise
and close on the Applewood Option (as defined in the Disclosure Materials List &
Statement) and, at Buyer's written request, with respect to any other similar
options or rights described on Exhibit V attached hereto, as soon as possible
after the closing, provided such option(s) shall not be exercised or caused to
be exercised by Buyer prior to the closing and Transferors shall not be required
to exercise such option(s) prior to the closing);

                 (m) During the Contract Period, but subject to the provisions
of Sections 2.4 and 2.5, Transferors shall permit Buyer, and Buyer's lenders and
its representatives, to have reasonable access (upon reasonable notice, during
normal business hours and, if required by Transferors, accompanied by a
representative of Transferors) to the books, records and Properties, and, with
Transferors' prior approval not to be unreasonably withheld, tenants, parties to
REAs, parties to options and rights of first refusal, and parties to management
agreements and Contracts, in order to assist Buyer in its management transition
with respect to the Properties and to provide information to its lenders that is
reasonably requested by them;

                 (n) As a courtesy to Buyer, during the Contract Period,
Transferors shall use reasonable efforts to provide Buyer with copies of any
written notices received by Transferors during the Contract Period, which
notices relate to matters described in Section 4.1(b)(i), (ii), (iii), (iv),
(vi), (vii) or (viii); provided, that notwithstanding anything to the contrary
contained in this Agreement, Transferors shall have no liability whatsoever to
Buyer as a result of its failure to comply with the provisions of this Section
4.2(n);

                 (o) During the Contract Period, Transferors shall provide
reasonable access to the Disclosure Materials (upon reasonable notice and during
normal business hours) and the right





                                       20
<PAGE>   24

to copy such materials (at no cost to Transferors) in order to assist Buyer in
its management transition with respect to the Properties and to provide
information to its lenders that is reasonably requested by them;

                 (p) During the Contract Period, Transferors shall meet and
confer with Buyer on a regular basis to discuss leasing activity at the
Properties and the status of work described in Section 6.9 and shall provide
Buyer at such meetings or otherwise reasonably detailed information regarding
the costs incurred with respect to, and the costs anticipated to complete, such
work;

                 (q) During the Contract Period, Transferors shall notify Buyer
of any litigation filed against Transferors during the Contract Period within a
reasonable period of time after Transferors are made aware of such litigation
and Exhibit W shall be revised to include such litigation; and

                 (r) During the Contract Period, to the extent Transferors have
a right of first offer or right of first refusal to purchase any real property
related to any of the Properties and Transferors receive written notice that the
period for exercising such right has commenced, Transferors shall promptly
notify Buyer and Buyer shall have the right, by written notice to Transferors,
to request that at closing Transferors assign such right to Buyer (if
assignable) or use reasonable efforts to cause the applicable property to be
direct deeded to Buyer; provided, that in no event shall Transferors have any
liability or incur any cost with respect to such property or be required to take
title to such property, and Buyer shall deliver to Title Company at the times
required in connection with such right to purchase, and remain responsible for,
any funds to be paid in connection with the acquisition of such property.

         SECTION 4.3 Buyer's Warranties and Representations. Buyer hereby
represents and warrants to Transferors that the following are true as of the
date of this Agreement:

                 (a) Buyer is a duly formed and validly existing limited
liability company under the law of the state of its formation and is (or on the
Closing Date will be) in good standing under the laws of the states where each
Property is located and Buyer has the full right, authority and power to enter
into this Agreement, to consummate the transactions contemplated herein and to
perform its obligations hereunder and under those documents and instruments to
be executed by it at the closing, and each of the individuals executing this
Agreement on behalf of Buyer is authorized to do so, and this Agreement
constitutes a valid and legally binding obligation of Buyer enforceable against
Buyer in accordance with its terms.

                 (b) Buyer's execution and delivery of this Agreement, the
consummation of the transactions contemplated hereby and the performance of
Buyer's obligations under the instruments required to be delivered by Buyer at
the closing, do not and will not result in any material violation of, or
material default under, any term or provision of any agreement, instrument,
mortgage, loan agreement or similar document to which Buyer is a party or by
which Buyer is bound.

                 (c) There is no litigation, investigation or proceeding pending
or, to the best of Buyer's knowledge, contemplated or threatened against Buyer
which would impair or





                                       21
<PAGE>   25

adversely affect Buyer's ability to perform its obligations under this Agreement
or any other instrument or document related hereto.

         SECTION 4.4 Survival/Limitations.

                 (a) Subject to subsection (b) below, the parties agree that
Transferors' warranties and representations contained in Sections 4.1 (a) and
(b) of this Agreement shall survive Buyer's purchase of the Properties and the
Closing Date for a period ending 180 calendar days following the Closing Date
(the "Limitation Period"). Such termination as of the close of the Limitation
Period shall apply to known as well as unknown breaches of such warranties or
representations. Subject to subsection (b) below, Buyer's waiver and release set
forth in Section 2.4 shall apply fully to liabilities under such representations
and warranties. Buyer specifically acknowledges that such termination of
liability represents a material element of the consideration to Transferors.

                 (b) Any claim of Buyer based upon a breach of any
representation or warranty or covenant or a claim under any indemnity contained
in this Agreement or any representation, warranty, covenant or indemnity
contained in any other document or instrument delivered by Transferors to Buyer
at closing (collectively a "Breach") shall be expressed, if at all, in writing
setting forth in reasonable detail the basis and character of the claim (a
"Claim Notice"), and, in the case of a Breach of Transferors' representations
and warranties contained in this Agreement or a Breach of a covenant contained
in Section 4.2 hereof only, shall be delivered to Transferors prior to the
expiration of the Limitation Period. Notwithstanding the foregoing, Buyer's
right to make and recover any claim pursuant to a Claim Notice shall be subject
to the following: (i) any matters identified by Buyer during the Confirmation
Period which would represent both a breach of representation and result in a
Material Adverse Matters Amount shall be treated solely as the latter and shall
not be the subject of any claim for breach of representation under this Article
IV, (ii) with respect to a Breach of Transferors' representations and warranties
contained in this Agreement, or a Breach of a covenant contained in Section 4.2
hereof or a Breach under an indemnity contained in the Assignments of
Intangibles or the Assignments of Leases (as such terms are defined in Section
6.1(a) below), Buyer shall not make any claim on account of such Breach unless
and until (A) the aggregate measure of such claims with respect to a Property
exceeds $200,000, and (B) the aggregate measure of such claims with respect to
all of the Properties exceeds $900,000 (the "Threshold"), in which event Buyer's
claim shall be limited to an amount equal to (x) the amount by which such
aggregate exceeds the Threshold, plus (y) an amount equal to two-thirds of the
Threshold, (iii) Transferors' aggregate liability for claims arising out of all
Breaches (i.e., those described in clause (ii) above as well as all other
Breaches) shall not, in the aggregate, exceed an amount equal to three percent
(3%) of the aggregate Price for all of the Properties acquired by Buyer
exclusive of the amounts of any insurance proceeds actually received by
Transferors which are to be applied to Claims pursuant to Section 2.4(e), and
(iv) Buyer shall have the right to deliver to Transferors Claim Notices with
respect to any Breach discovered by Buyer prior to the Closing Date solely if
such notice is delivered prior to the Closing Date. Notwithstanding the
foregoing, with respect to a Claim Notice asserting a breach of the
representation contained in Section 4.1(b)(vii), the following shall be
substituted for the provisions of clause (ii) of this Section 4.4(b): (ii) Buyer
shall not make any claim on account of a breach of the representation and
warranty contained in Section 4.1(b)(vii) with respect to any Property unless
and until the aggregate measure of such claims with respect to all






                                       22
<PAGE>   26

Properties exceeds $50,000, and only to the extent that such aggregate exceeds
$50,000. For purposes of this Section 4.4(b) (and without limiting the
introductory paragraph of Section 4.1), a Breach shall be deemed to be
discovered by Buyer prior to the Closing Date only to the extent that any of
David Martin, Daniel Platt, Joseph Byrne, Scott Verges, John Waters, Jim Gaube
or Guy Jacquier has actual, subjective knowledge of the facts or circumstances
giving rise to such breach of representation or warranty or Section 4.2
covenants. Following receipt of such a pre-closing Claim Notice with respect to
which Buyer has the right to make and recover a claim as aforesaid, Transferors
may elect, by written notice to Buyer given not later than the first to occur of
the date that is ten (10) business days following the date of the Claim Notice
or the Closing Date, to terminate this Agreement as to the Property to which
such pre-closing Claim Notice relates and such Property shall be treated as a
Deleted Property and Buyer shall not be entitled to any damages in connection
therewith. If Transferors fail to elect to treat any Property which is the
subject of a pre-closing Claim Notice as a Deleted Property, the closing as to
such Property shall be conducted on the Closing Date. As to pre-closing Claim
Notices with respect to which Transferors do not elect to treat the affected
Property as a Deleted Property and as to all Claim Notices received by
Transferors following the Closing Date as to which Buyer has the right to make
and recover a claim as aforesaid, Buyer shall have the right after (but not
before) the Closing Date to proceed against Transferors for actual monetary
damages based upon such Claim Notice -- subject to the cure rights set forth in
subparagraph (c) below and the limitations set forth above and in the remaining
sentences of this subparagraph. Notwithstanding anything to the contrary
provided in this Agreement, in no event shall Transferors be liable to Buyer for
any consequential or punitive damages based upon any breach of this Agreement,
including breaches of representation or warranty. Subject to applicable
principles of fraudulent conveyance, in no event shall Buyer seek satisfaction
for any obligation from any shareholders, officers, directors, employees,
agents, legal representatives, successors or assigns of such trustees or
beneficiaries, nor shall any such person or entity have any personal liability
for any such obligations of any Transferors.

                 (c) The Transferors who have committed a Breach for which a
Claim Notice has been received shall have a period of 30 days within which to
cure such breach, or, if such breach cannot reasonably be cured within 30 days,
an additional reasonable time period of up to an additional 60 days, so long as
such cure has been commenced within such 30 days and is at all times diligently
pursued. If the Breach is not cured after actual written notice and within such
cure period, Buyer's sole remedy shall be an action at law for damages against
the breaching Transferor or Transferors, which must be commenced with respect to
a Breach of a representation or warranty contained in this Agreement or a Breach
of a covenant contained in Section 4.2 hereof, if at all, within the Limitation
Period; provided, however, that if within the Limitation Period Buyer gives a
Claim Notice and the Transferors commence to cure and thereafter terminate such
cure effort or fail in such cure effort, Buyer shall have an additional 30 days
from the date of written notice from the Transferors of such termination or the
expiration of such cure period within which to commence an action at law for
damages as a consequence of the failure to cure. The existence or pendency of
such cure rights shall not delay the Closing Date as to a Property not
designated as a Deleted Property. The provisions of this Section 4.4 shall
survive the closing or any termination of this Agreement.

                                DEPOSIT; DEFAULT

         SECTION 5.1 Buyer's Default & Deposit.

                 (a) Substantially concurrently with the execution and delivery
of this Agreement, Buyer shall deliver to Title Company, for deposit into the
escrow described in Section 6.1 below, cash in an amount equal to Eleven Million
Dollars ($11,000,000) (the "Deposit"). In the event that this transaction is
consummated as contemplated by this Agreement, then the entire amount of the
Deposit, together with any interest accrued thereon, whether in cash or in the
form of a Letter of Credit (as herein defined) shall be returned to Buyer and in
no event shall the Deposit be credited against the Price. The entire amount of
the Deposit (or the portion of the Deposit allocable to Properties with respect
to which Transferors refuse to perform their material closing obligations),
together with any interest accrued thereon, shall be returned immediately to
Buyer in the event that the transaction fails to close due to termination of
this Agreement pursuant to Section 5.2. IN THE EVENT THE TRANSACTION
CONTEMPLATED BY THIS AGREEMENT SHOULD FAIL TO CLOSE AS A RESULT OF BUYER'S
DEFAULT HEREUNDER, THE ENTIRE AMOUNT OF THE DEPOSIT, PLUS ACCRUED INTEREST, (AND
TO THE EXTENT THE DEPOSIT IS IN THE FORM OF A LETTER OF CREDIT, TITLE COMPANY
SHALL IMMEDIATELY MAKE DEMAND FOR THE PRINCIPAL AMOUNT OF THE LETTER OF CREDIT)
SHALL BE PAID BY THE TITLE COMPANY TO TRANSFERORS AS LIQUIDATED DAMAGES (THE
"LIQUIDATED AMOUNT"). BUYER AND TRANSFERORS HEREBY ACKNOWLEDGE AND AGREE THAT
TRANSFERORS' DAMAGES IN THE EVENT OF SUCH A BREACH OF THIS AGREEMENT BY BUYER
WOULD BE DIFFICULT OR IMPOSSIBLE TO DETERMINE, THAT THE AMOUNT OF THE DEPOSIT
PLUS ACCRUED INTEREST IS THE PARTIES' BEST AND MOST ACCURATE ESTIMATE OF THE
DAMAGES TRANSFERORS WOULD SUFFER IN THE EVENT THE TRANSACTION PROVIDED FOR IN
THIS AGREEMENT FAILS TO CLOSE, AND THAT SUCH ESTIMATE IS REASONABLE UNDER THE
CIRCUMSTANCES EXISTING ON THE DATE OF THIS AGREEMENT. BUYER AND TRANSFERORS
AGREE THAT TRANSFERORS' RIGHT TO RETAIN THE DEPOSIT PLUS ACCRUED INTEREST SHALL
BE THE SOLE REMEDY OF TRANSFERORS IN THE EVENT OF A BREACH OF THIS AGREEMENT BY
BUYER.

ACCEPTED AND AGREED TO:

BUYER'S INITIALS                   TRANSFEROR'S INITIALS

This Section 5.1 is intended only to liquidate and limit Transferors' rights to
damages arising due to Buyer's failure to purchase the Properties and shall not
limit the indemnification or other obligations of (i) Buyer's constituent
partners pursuant to the Confidentiality Agreement dated January 25, 1999
executed by Burnham Pacific Properties, Inc. for the benefit of Transferors (the
"BP Confidentiality Agreement") and the Confidentiality Agreement dated January
25, 1999 executed by the State of California Public Employees' Retirement System
("Calpers") for the benefit of Transferors (the "Calpers Confidentiality
Agreement;" which, together with the BP





                                       24
<PAGE>   28

Confidentiality Agreement, are collectively referred to as the "Confidentiality
Agreements") or (ii) Buyer pursuant to (A) any other documents delivered
pursuant to this Agreement or (B) Sections 2.4(b), 2.4(e), 7.2, 7.9 and 7.13 of
this Agreement. In the event that any Property becomes a Deleted Property
pursuant to the provisions of this Agreement, then Buyer shall have the right to
cause Title Company to withdraw from the escrow and pay to Buyer (or to reduce
any letter of credit, as applicable, by) an amount equal to the product of (x)
the Deposit (and interest accruing thereon) and (y) the quotient expressed as a
percentage, of the Allocated Price with respect to such Deleted Property and the
total Price.

                 (b) In the event that Transferors are entitled to the Deposit
pursuant to Section 5.1 hereof, an amount equal to the lesser of (i) the
Liquidated Amount or (ii) the sum of (A) the maximum amount that can be paid to
Transferors without causing Transferors (or any of their constituent partners)
to fail to meet the requirements of Sections 856(c)(2) and 856(c)(3) of the
Code, determined as if the payment of such amount did not constitute income
described in Section 856(c)(2)(A)-(H) and 856(c)(3)(A)-(I) of the Code
("Qualifying Income"), as determined by Transferors' accountants, plus (B) in
the event Transferors receive either (x) a letter from Transferors' counsel
prior to the Closing Date indicating that Transferors (or their constituent
partners, as applicable) has received a ruling from the Internal Revenue Service
(the "IRS") described in clauses (ii) or (iii) of the following paragraph, or
(y) an opinion from Transferors' (or their constituent partners', as applicable)
counsel as described in clause (iv) of the following paragraph, an amount equal
to the Liquidated Amount less the amount payable under clause (A) above, and any
balance of the Liquidated Amount (the "Balance") shall be retained by Title
Company in escrow in accordance with the terms of an escrow (subject to the
terms of the following paragraph) being otherwise agreed upon by Transferors and
the escrow agent.

                 (c) The escrow agreement described in Section 5.1(b) shall
provide that the amount in escrow or any portion thereof shall not be released
to Transferors except to the extent the escrow agent receives any one or
combination of the following: (i) a letter from Transferors' accountants
indicating the maximum amount that can be paid by the escrow agent to
Transferors without causing Transferors (or any of their constituent partners,
as applicable) to fail to meet the requirements of Sections 856(c)(2) and
856(c)(3) of the Code, determined as if the payment of such amount did not
constitute Qualifying Income, in which case the escrow agent shall release the
amount indicated in such letter to Transferors, (ii) a letter from Transferors'
(or any of their constituent partner's, as applicable) counsel indicating that
Transferors (or any of its constituent partners, as applicable) received a
ruling from the IRS holding that the receipt by Transferors (or any of their
constituent partners, as applicable) of the Liquidated Amount would either
constitute Qualifying Income or would be excluded from gross income within the
meaning of Sections 856(c)(2) and 856(c)(3) of the Code, in which case the
escrow agent shall release the Balance to Transferors, (iii) a letter from
Transferors' (or any of their constituent partners' as applicable) counsel
indicating that Transferors (or any of their constituent partners, as
applicable) received a ruling from the IRS holding that the receipt by a
Transferor (or its constituent partner, as applicable) of the Balance following
the receipt of and pursuant to such ruling would not be deemed constructively
received prior thereto or (iv) an opinion of a Transferor's (or its constituent
partner's, as applicable) legal counsel to the effect that the receipt by a
Transferor (or its constituent partner, as applicable) of the Liquidated Amount
would either constitute Qualifying Income or would be excluded from gross income
within the meaning of Sections 856(c)(2) and 856(c)(3) of the Code, in which
case the escrow agent shall release the

Balance to Transferors. Buyer and Title Company agree to act reasonably and
cooperate with Transferor in order (x) to maximize the portion of the Liquidated
Amount that may be distributed to Transferors hereunder without causing a
Transferor (or its constituent partner, as applicable) to fail to meet the
requirements of Sections 856(c)(2) and 856(c)(3) of the Code or (y) to improve a
Transferor's (or any of their constituent partner's, as applicable) chances of
securing a favorable ruling described in this Section 5.1(c), provided that,
except as otherwise provided in this Agreement, Buyer and Title Company shall
not be required to incur any out-of-pocket costs in connection therewith. The
escrow agreement shall also provide that any portion of the Liquidated Amount
then held in escrow after the expiration of five (5) years from the date of the
establishment of such escrow shall be released by the escrow agent to Buyer.
Buyer shall not be a party (other than a contingent beneficiary as described
above) to such escrow arrangements and shall not bear any cost of or have
liability resulting from such escrow arrangements.

         SECTION 5.2 Transferors' Default. If (a) the conditions precedent set
forth in Section 3.1(b) shall have been satisfied or waived (provided that for
purposes of this Section Buyer shall not be required to tender formally the
Price but only demonstrate the commitment of immediately available funds to pay
such Price) and (b) Transferors shall refuse to perform their material closing
obligations under this Agreement (e.g., by refusing to convey a Property to
Buyer at Closing), then Buyer's sole and exclusive remedy shall be either (i) to
receive back the Deposit in the event Transferors refused to perform their
material closing obligations with respect to all of the Properties (or the
portion of the Deposit allocable to Properties with respect to which Transferors
refuse to perform their material closing obligations) plus all accrued interest
thereon or (ii) to pursue an action for specific performance on a Property by
Property basis as to those Properties with respect to which Transferors refuse
to perform their material closing obligations ; provided, that notwithstanding
anything to the contrary contained herein, Buyer's right to pursue an action for
specific performance is expressly conditioned on Buyer not being in default or
having defaulted in any material respect under any other material agreement in
which Buyer or any of its constituent members and any of the Transferors is a
party and which was entered into on or after March 1, 1999. Subject to the
foregoing, Buyer acknowledges that Buyer's remedies for Transferor's failure to
perform all of its material obligations under this Agreement with respect to the
sale or exchange of a particular Property but less than all of the Properties
shall be exclusively governed by the provisions of Section 3.2 above. Nothing
contained in this Section 5.2 is intended to limit Buyer's rights under Sections
7.2, 7.9 and 7.13 of this Agreement.

         SECTION 5.3 Solicitation; Negotiations.

                 (a) Unless and until this Agreement shall have been terminated
in accordance with its terms, the Transferors agree and covenant that (i)
neither Transferors nor any of their respective subsidiaries or affiliates nor
AMB Property Corporation, a Maryland corporation, which is AMBLP's general
partner (the "Company"), shall, and each of them shall direct and use their best
efforts to cause their respective officers, directors, employees, agents and
representatives (including, without limitation, any investment banker, attorney
or accountant retained by it or any of its subsidiaries) not to, directly or
indirectly, initiate, solicit or encourage any inquiries or the making or
implementation of any proposal or offer with respect to a merger, acquisition,
or similar transaction involving the direct or indirect purchase of the
Properties (any such proposal or offer being hereinafter referred to as an
"Acquisition Proposal") or engage in





                                       26
<PAGE>   30

any negotiations with, or provide any confidential information or data to, or
have any discussions with, any person relating to, an Acquisition Proposal, or
otherwise facilitate any effort or attempt to make or implement an Acquisition
Proposal.

                 (b) Notwithstanding anything set forth in this Agreement to the
contrary, the Board of Directors of the Company may furnish information to or
enter into discussions or negotiations with any person that makes an unsolicited
bona fide proposal to purchase all or a portion of the Properties having
aggregate Allocated Price of at least eighty-five percent (85%) of the aggregate
Price of all of the Properties, whether by merger, purchase of partnership
interests or assets or otherwise (a "Proposal"), if the Board of Directors of
the Company determines in good faith that the Proposal, if consummated as
proposed, would result in a transaction more favorable to the Company's
stockholders from a financial point of view than the transactions contemplated
by this Agreement (any such Proposal being referred to herein as a "Superior
Proposal"). If the Board of Directors of the Company is prepared to accept the
Superior Proposal, then Transferors shall have the right to terminate this
Agreement by giving Buyer 48 hours notice that the Board of Directors is
prepared to accept the Superior Proposal, instructing the Title Company to
return the Deposit to Buyer and in addition paying Buyer a termination fee in
the amount of the then current Deposit (as increased or decreased from time to
time pursuant to this Agreement) (excluding the amount of any remaining Deposit
allocable to any Properties which were previously designated as Deleted
Properties) (the "Termination Fee"). The return of the Deposit (and all interest
accrued thereon) and the additional payment of the Termination Fee shall be
Buyer's sole and exclusive remedy in the event of a termination pursuant to this
Section 5.3

                 (c) In addition to the provisions set forth in Sections 5.3(a)
and 5.3(b) hereof, nothing in this Agreement shall be deemed to prevent in any
manner the taking of any action by the Company with respect to any merger,
consolidation or sale of all or substantially all of the assets of the Company
or any of the Transferors, in the event that the Board of Directors of the
Company shall determine, based on advice of outside legal counsel, that the
failure to take such action would be inconsistent with such Board of Directors'
fiduciary duties to the Company's stockholders under applicable law. In the
event that such action would be inconsistent with the transactions contemplated
hereby, then Transferors shall have the right to terminate this Agreement by
giving Buyer 48 hours notice that such Board of Directors is prepared to take
such action, instructing the Title Company to return the Deposit to Buyer and in
addition paying Buyer the Termination Fee. The return of the Deposit and the
additional payment of the Termination Fee shall be Buyer's sole and exclusive
remedy in the event of a termination pursuant to this Section 5.3.

                 (d) In the event that Transferors are obligated to pay Buyer
the Termination Fee, Transferors shall pay to Buyer an amount equal to the
lesser of (i) the Termination Fee or (ii) the sum of (A) the maximum amount that
can be paid to Buyer without causing Buyer (or any of its members) to fail to
meet the requirements of Sections 856(c)(2) and 856(c)(3) of the Code,
determined as if the payment of such amount did not constitute income described
in Section 856(c)(2)(A)-(H) and 856(c)(3)(A)-(I) of the Code ("Qualifying
Income"), as determined by Buyer's accountants, plus (B) in the event Buyer
receives either (x) a letter from Buyer's counsel prior to the Closing Date
indicating that Buyer (or its members, as applicable) has received a ruling from
the Internal Revenue Service (the "IRS") described in clauses (ii) or (iii)





                                       27
<PAGE>   31

of the following paragraph, or (y) an opinion from Buyer's (or its member's, as
applicable) counsel as described in clause (iv) of the following paragraph, an
amount equal to the Termination Fee less the amount payable under clause (A)
above, and any balance of the Termination Fee (the "Balance") shall be deposited
by Transferors in escrow in accordance with the next succeeding sentence with
the Title Company or other escrow agent selected by Buyer and reasonably
acceptable to Transferors. Transferors shall deposit into such escrow an amount
in immediately available federal funds equal to the Balance, with the terms of
such escrow (subject to the terms of the following paragraph) being otherwise
agreed upon by Buyer and the escrow agent. All payments by Transferors pursuant
to this paragraph shall be made by wire transfer or bank check within thirty
(30) days after demand by Buyer. Payment to Buyer of the amounts set forth in
this Section 5.3(d) and, if applicable, deposit into escrow of the Balance,
shall satisfy Transferors' obligations in full under the terms and conditions of
this Section 5.3.

                 (e) The escrow agreement described in Section 5.3(d) shall
provide that the amount in escrow or any portion thereof shall not be released
to Buyer except to the extent the escrow agent receives any one or combination
of the following: (i) a letter from Buyer's accountants indicating the maximum
amount that can be paid by the escrow agent to Buyer without causing Buyer (or
its member, as applicable) to fail to meet the requirements of Sections
856(c)(2) and 856(c)(3) of the Code, determined as if the payment of such amount
did not constitute Qualifying Income, in which case the escrow agent shall
release the amount indicated in such letter to Buyer, (ii) a letter from Buyer's
(or its member's, as applicable) counsel indicating that Buyer (or its member,
as applicable) received a ruling from the IRS holding that the receipt by Buyer
(or its member, as applicable) of the Termination Fee would either constitute
Qualifying Income or would be excluded from gross income within the meaning of
Sections 856(c)(2) and 856(c)(3) of the Code, in which case the escrow agent
shall release the Balance to Buyer, (iii) a letter from Buyer's (or its
member's, as applicable) counsel indicating that Buyer (or its member, as
applicable) received a ruling from the IRS holding that the receipt by Buyer (or
its member, as applicable) of the Balance following the receipt of and pursuant
to such ruling would not be deemed constructively received prior thereto or (iv)
an opinion of Buyer's (or its member's, as applicable) legal counsel to the
effect that the receipt by Buyer (or its member, as applicable) of the
Termination Fee would either constitute Qualifying Income or would be excluded
from gross income within the meaning of Sections 856(c)(2) and 856(c)(3) of the
Code, in which case the escrow agent shall release the Balance to Buyer.
Transferors agree to act reasonably and cooperate with Buyer in order (x) to
maximize the portion of the Termination Fee that may be distributed to Buyer
hereunder without causing Buyer (or its member, as applicable) to fail to meet
the requirements of Sections 856(c)(2) and 856(c)(3) of the Code or (y) to
improve Buyer's (or its member's, as applicable) chances of securing a favorable
ruling described in this Section 5.3(e), provided that Transferors shall not be
required to incur any out-of-pocket costs in connection therewith. The escrow
agreement shall also provide that any portion of the Termination Fee then held
in escrow after the expiration of five (5) years from the date of the
establishment of such escrow shall be released by the escrow agent to
Transferors. Transferors shall not be a party (other than a contingent
beneficiary as described above) to such escrow arrangements and shall not bear
any cost of or have liability resulting from such escrow arrangements.

         SECTION 5.4 Letter of Credit. In lieu of depositing the Deposit in cash
pursuant to this Agreement, or after depositing the Deposit in cash, in
substitution for all or any portion of the





                                       28
<PAGE>   32

cash Deposit, Buyer may deliver to Title Company an unconditional and
irrevocable letter of credit in favor of Title Company, in form reasonably
satisfactory to Transferors and Title Company, drawn upon a state or national
bank reasonably approved by Transferors and Title Company, which letter of
credit shall (i) expire no earlier than fifteen (15) days after the scheduled
Closing Date (as such date may be changed with respect to all of the Properties
or a particular Property pursuant to this Agreement), (ii) be capable of being
drawn on by Title Company upon demand (subject to customary draw procedures and
requirements) and (iii) otherwise be in form and substance reasonably
satisfactory to Transferors and Title Company (the "Letter of Credit"). The
Letter of Credit shall secure the faithful performance and observance by Buyer
of the terms, provisions, and conditions of this Agreement in the same manner
and to the same extent as the Deposit. The Letter of Credit shall be held and
disbursed by Title Company in the same manner as the Deposit, except that:

                 (a) if the term of the Letter of Credit will expire prior to
the then scheduled Closing Date (as such date may be changed with respect to all
of the Properties or a particular Property pursuant to this Agreement), and such
Letter of Credit is not extended or a new Letter of Credit for an extended
period of time is not substituted within five (5) business days prior to the
expiration date of the Letter of Credit, then Title Company shall make demand
for the principal amount of the Letter of Credit prior to the expiration date of
the Letter of Credit and hold such funds in the same manner as the Deposit
pursuant to this Agreement;

                 (b) if Title Company continues to hold the Letter of Credit at
closing and the closing occurs as contemplated by this Agreement, subject to (c)
below such Letter of Credit shall be returned to Buyer at closing; and

                 (c) in any instance in which a portion of the Deposit is to be
returned to Buyer pursuant to this Agreement or in which a closing occurs and
subsequent closings are contemplated due to the deferral of the closing with
respect to one or more of the Properties and in order to do so the amount of the
Letter of Credit would have to be reduced, the Title Company shall continue to
hold the Letter of Credit in the manner set forth in and subject to the
provisions of this Section 5.4 until Buyer has provided a substitute Letter of
Credit in the amount of the Deposit as so reduced.


                                    ARTICLE 6
                                     CLOSING

         SECTION 6.1 Escrow Arrangements. One or more escrows (to the extent
more than one escrow is necessary to accommodate Transferors' 1031 Exchange(s))

Buyer and Transferors with Title Company. At least one business day prior to the
Closing Date, Transferors and Buyer shall each deliver escrow instructions to
Title Company consistent with this Article VI, and designating Title Company as
the "Reporting Person" for the transaction pursuant to Section 6045(e) of the
Code. By signing below, Title Company agrees to act as the "Reporting Person"
for the transaction pursuant to Section 6045(e) of the Code and to complete and
file with the IRS Forms 1099-S (and furnish Buyer and Transferors with copies
thereof) on or before the due date therefor. In addition, the parties shall
deposit in escrow, at least one business day prior to the Closing Date (unless
otherwise provided below in this Section 6.1) the funds and documents described
below:

<PAGE>   35

Remediation and Access Agreement executed by Buyer, (ii) the certificate
described in Section 6.1(b)(iii) above, (iii) funds in the amount of the Sale
Purchase Price, as adjusted for credits, adjustments, prorations and closing
costs in accordance with Section 2.3 and this Article VI and as allocated

Title Company shall have the right to conclusively rely) and (iv) funds in the
amount of the Exchange Price, as adjusted for credits, adjustments, prorations
and closing costs in accordance with Section 2.3 and this Article VI and as
allocated pursuant to the direction of the Transferors (upon which allocation
Buyer and Title Company shall have the right to conclusively rely); and

                 (e) if directed by the parties, delivering the Tenant Notices

         SECTION 6.3 Prorations.

                 (a) Taxes. Real estate taxes, personal property taxes and any
general or special assessments with respect to the Properties which are not the
direct payment obligation of tenants pursuant to the Leases (as opposed to a
reimbursement obligation) shall be prorated as of the Closing Date -- to the end
that Transferors shall be responsible for all taxes and assessments that are
allocable to any period prior to the Closing Date and Buyer shall be responsible
for all taxes and assessments that are allocable to any period from and after
the Closing Date. Notwithstanding anything to the contrary contained herein, in
regards to Real Property located in the States of Illinois and Colorado, (A)
general real estate taxes which are not the direct or indirect (as a
reimbursement obligation) payment obligations of tenants pursuant to the Leases
and which are payable for the tax year prior to the tax year in which the
closing occurs and all prior years shall be paid by Transferors (including any
installments thereof payable after the Closing Date) and (B) general real estate
taxes which are not the direct or indirect (as a reimbursement obligation)
payment obligations of tenants pursuant to the Leases and which are payable for
the tax year in which the closing occurs shall be prorated by Transferors and
Buyer as of the Closing Date. If the actual amount of taxes, assessments or
other amounts to be prorated for the year in which the closing occurs (and, with
respect to Real Property located in Illinois and Colorado, for the tax year
prior to the tax year in which the closing occurs) is not known as of the
Closing Date, the proration shall be based on the parties' reasonable estimates
of such taxes, assessments and other amounts. To the extent any real or personal
property taxes subject to apportionment in accordance with the foregoing are, as
of the Closing Date, the subject of any appeal filed by or on behalf of
Transferors, then notwithstanding anything to the contrary contained in this
subparagraph, (i) no apportionment of the taxes being appealed shall occur at
the closing, but instead such apportionment shall be deferred until the outcome
of the appeal is final and the amount of taxes owing becomes fixed at which time
Transferors shall be responsible for all such taxes that are allocable to any
period prior to the Closing Date and Buyer shall be responsible for all such
taxes that are allocable to any period from and after the Closing Date, and (ii)
Transferors shall provide Buyer with adequate security, either in the form of a
bond or by escrowing the amounts being appealed, to assure Buyer that
Transferors' portion of such tax liability, including any penalty, will be
available. To the extent any taxes which are the subject of an appeal have been
paid by Transferors under protest and the appeal results in Buyer receiving a
credit toward future tax liability or a refund, then Buyer shall, within thirty
(30) days following receipt of such refund or notice of such credit, pay to
Transferors the full amount of such refund or credit allocable to the period
prior to the Closing Date, excluding, however, any





                                       32
<PAGE>   36

portion of such refund or credit that is required to be passed through to the
tenants pursuant to any Leases or to other parties by existing contract.

                 (b) Prepaid Expenses. Buyer shall be charged for those prepaid
expenses paid by Transferors directly or indirectly allocable to any period from
and after the Closing Date, including, without limitation, annual permit and
confirmation fees, fees for licenses and all security or other deposits paid by
Transferors to third parties which Buyer elects to assume and to which Buyer
then shall be entitled to the benefits and refund following the Closing Date.

                 (c) Property Income and Expense. The following prorations and
adjustments shall occur as of the closing. Prior to the Closing Date,
Transferors shall provide all information to Buyer required to calculate such
prorations and adjustments and representatives of Buyer and Transferors shall
together make such calculations:

                     (i) General. Subject to the specific provisions of clauses
(ii), (iii) and (iv) below, income and expense shall be prorated on the basis of
a 30-day month and on a cash basis (except for items of income and expense that
are payable less frequently than monthly, which shall be prorated on an accrual
basis). All such items attributable to the period prior to the Closing Date
shall be credited to Transferors; all such items attributable to the period on
and following the Closing Date shall be credited to Buyer. Buyer shall be
credited in escrow with (a) any portion of rental agreement or lease deposits
which are refundable to the tenants and have not been applied to outstanding
tenant obligations in accordance with the terms of the applicable Lease and (b)
rent prepaid beyond the Closing Date. Transferors shall transfer Transferors
entire interest in any letters of credit or certificates of deposit held by
Transferors as the deposits described in clause (a) above and shall diligently
cooperate with Buyer in obtaining any reissuance or confirmation of the effect
of the transfer of such instruments. Buyer shall not be entitled to any interest
on rental agreement or lease deposits or prepaid rent accrued on or before the
Closing Date, except to the extent any such amount of interest is refundable or
payable to any tenant under a Lease or applicable law. Transferors shall be
credited in escrow with any refundable deposits or bonds held by any utility,
governmental agency or service contractor, to the extent such deposits or bonds
are assigned to Buyer on the Closing Date.

                     (ii) Leasing Costs. Subject to the provisions of Section
6.9 below, Buyer shall be credited in escrow with any leasing commissions,
tenant improvements or other allowances to be paid by Buyer on or after the
Closing Date with respect to the current term of any Lease or Lease modification
executed, or any extension term or expansion of premises exercised, in each
case, on or before March 1, 1999, and Transferors shall pay on or before the
Closing Date all such items payable prior to the Closing Date. Notwithstanding
the provisions of the immediately following sentence, with respect to any new
Leases or Lease modifications executed after March 1, 1999 with respect to any
of the space identified on Exhibit S attached hereto which are permitted under
the terms of this Agreement ("Vacant Space"), Transferors shall be credited in
escrow with the amount of any leasing commissions, tenant improvements or other
allowances paid by Transferors after March 1, 1999. Buyer shall receive a credit
at closing against the Price in the amount of $7.00 per square foot of Vacant
Space, whether or not such space is leased prior to closing. With respect to any
space which is not Vacant Space, subject to Section 6.9 Transferors shall be
credited in escrow with an amount equal to (A) the amount of any leasing
commissions, tenant improvement and other allowances paid by Transferors after





                                       33
<PAGE>   37

March 1, 1999 to the extent such items relate to new Leases or Lease
modifications executed or extensions of terms or expansions of premises that are
exercised after March 1, 1999 and permitted under the terms of this Agreement,
multiplied by (B) a fraction in which the numerator is the number of months or
partial months of the stabilized term (i.e., the term following the tenant's
entry into occupancy and commencement of unabated rental obligations) of any
such Lease following the Closing Date and the denominator is the number of
months or partial months in the stabilized term of such Lease. Buyer shall
assume all obligations for any leasing commissions, tenant improvement or other
allowances payable following the Closing Date with respect to Leases or Lease
modifications executed or extensions of terms or expansions of premises that are
exercised following March 1, 1999 and which are permitted under the terms of
this Agreement; provided, that as to any such leasing commissions not disclosed
to Buyer in the Disclosure Materials List & Statement or the Disclosure
Materials or approved or deemed approved by Buyer pursuant to this Agreement or
which are not expressly assumed by Buyer under any other provision of this
Agreement, Buyer shall only be obligated to pay the market rate commission for
the applicable Lease (and Transferors shall remain responsible for any above
market component of such commission). Any expenditures or commitments to
expenditures relating to Leases or modifications or extensions of terms or
expansions of premises executed following March 1, 1999 in excess of the amounts
budgeted and approved as part of Buyer's approval of the Lease (where such
approval is required) shall be subject to Buyer's specific approval, which shall
not be unreasonably withheld and shall be deemed given if Buyer should fail to
approve or disapprove such excess expenditure within 5 business days following
Transferors' written request and delivery of material information reasonably
necessary to allow Buyer to make an informed decision.

                     (iii) Rents. Rents payable by tenants under the Leases,
shall be prorated as and when collected (whether such collection occurs prior
to, on, or after the Closing Date). Buyer shall receive a credit for the amounts
actually received before the Closing Date and which pertain to any period after
the Closing Date. Buyer shall not receive a credit at the closing for any rents
for the month in which the closing occurs which are in arrears and have not then
been received. As to any tenants who are delinquent in the payment of rent on
the Closing Date, Buyer shall use reasonable efforts (but shall not be required
to commence legal action or terminate or evict a tenant) to collect or cause to
be collected such delinquent rents following the Closing Date. Any and all rents
so collected by Buyer following the closing (less a deduction for all reasonable
collection costs and expenses incurred by Buyer) shall be successively applied
(after deduction for Buyer's reasonable collection costs) to the payment of (x)
rent due and payable in the month in which the closing occurs, (y) rent due and
payable in the months succeeding the month in which the closing occurs (through
and including the month in which payment is made) and (z) rent due and payable
in the months preceding the month in which the closing occurs. If all or part of
any rents or other charges received by Buyer following the closing are allocable
to Transferors pursuant to the foregoing sentence, then such sums shall be
promptly paid to Transferors. Transferors reserve the right to pursue any
damages remedy Transferors may have against any tenant with respect to such
delinquent rents, but shall have no right to exercise any other remedy under the
Lease (including, without limitation, termination or eviction).

                     (iv) Additional Rents. Any percentage rent, escalation
charges for real estate taxes, parking charges, operating and maintenance
expenses, escalation rents or charges,





                                       34
<PAGE>   38

electricity charges, cost of living increases or any other charges of a similar
nature other than fixed or base rent under the Leases (collectively, the
"Additional Rents") shall be prorated as of the Closing Date between Buyer and
Transferors on or before the date which is ninety (90) days following the end of
the calendar year in which the closing occurs based on the actual number of days
of the year and month which shall have elapsed as of the Closing Date. Prior to
the end of the calendar year in which the closing occurs, Transferors shall
provide Buyer with information regarding Additional Rents which were received by
Transferors prior to closing and the amount of reimbursable expenses paid by
Transferors prior to closing. On or before the date which is sixty (60) days
following the end of the calendar year in which the closing occurs, Buyer shall
deliver to Transferors a reconciliation of all expenses reimbursable by tenants
under the Leases, and the amount of Additional Rents received by Transferors and
Buyer relating thereto (the "Reconciliation"). Upon reasonable notice and during
normal business hours, each party shall make available to the other all
information reasonably required to confirm the Reconciliation. In the event of
any overpayment of Additional Rents by the tenants to Transferors, Transferors
shall promptly, but in no event later than fifteen (15) days after receipt of
the Reconciliation, pay to Buyer the amount of such overpayment and Buyer, as
the landlord under the particular Leases, shall pay or credit to each applicable
tenant the amount of such overpayment. In the event of an underpayment of
Additional Rents by the tenants to Transferors, Buyer shall pay to Transferors
the amount of such underpayment within fifteen (15) days following Buyer's
receipt of any such amounts from the tenants.

                 (d) Adjustments to Prorations. Subject to Section 6.3(a) and
6.3(c)(iv) above, after the closing, the parties shall from time to time, as
soon as is practicable after accurate information becomes available and in any
event within 180 days following the Closing Date, recalculate and reapportion
any of the items subject to proration or apportionment (i) which were not
prorated and apportioned at the closing because of the unavailability of the
information necessary to compute such proration, or (ii) which were prorated or
apportioned at the closing based upon estimated or incomplete information, or
(iii) for which any errors or omissions in computing prorations at the closing
are discovered subsequent thereto, and thereafter the proper party shall be
reimbursed based on the results of such recalculation and reapportionment.
Unless otherwise specified herein, all such reimbursements shall be made on or
before thirty (30) days after receipt of notice of the amount due. Any such
reimbursements not timely paid shall bear interest at a per annum rate equal to
ten percent (10%) from the due date until all such unpaid sums together with all
interest accrued thereon is paid if payment is not made within ten (10) days
after receipt of a bill therefor.

                 (e) Prior Year's Reconciliation. If the closing occurs before
Transferors have performed the annual reconciliation of Additional Rent for the
calendar year immediately preceding the calendar year in which the closing
occurs, then Transferors shall, as soon as practicable after closing, perform
such reconciliation at its sole cost and expense. Upon completion of such annual
reconciliation, Transferors shall immediately deliver to Buyer a detailed
description of any Additional Rent which are payable by or reimbursable to any
present tenant (the "Prior Year Reconciliation"). The Prior Year Reconciliation
shall be accompanied by all applicable back-up documentation, together with
Transferors' check for such Additional Rent which is reimbursable to a tenant.
Based upon Transferors' calculations, Buyer shall send customary statements for
reimbursement of Additional Rent to tenants under the Leases based on the Prior
Year Reconciliation, and shall remit to Transferors within thirty (30) days of
receipt, all





                                       35
<PAGE>   39

sums so collected. If Transferors' calculations show that Additional Rent has
been overpaid by any present tenant and Transferors have submitted its check to
Buyer for such amounts, Buyer shall refund such Additional Rent to such tenant.

                 (f) Survival. The provisions of this Section 6.3 shall survive
the closing.

         SECTION 6.4 Other Closing Costs.

                 (a) The premium payable in connection with the issuance of the
Title Policies, governmental documentary transfer or transaction taxes or fees
due on the transfer of the Properties, recording costs, and, except as otherwise
provided below, other closing costs shall be paid by Transferors and Buyer
according to custom in the county in which the applicable Property is located as
set forth on Exhibit D attached hereto.

                 (b) Transferors shall pay 50% of any escrow or other costs
charged by or reimbursable to the Title Company; provided, however that
additional costs to create multiple escrows to accommodate 1031 Exchanges shall
be borne by the party requesting such multiple escrows.

                 (c) Buyer shall pay 50% of any escrow or other costs charged by
or reimbursable to the Title Company; provided, however that additional costs to
create multiple escrows to accommodate 1031 Exchanges shall be borne by the
party requesting such multiple escrows.

         SECTION 6.5 Further Documentation. At or following the close of escrow,
Buyer and Transferors shall execute any certificate, memoranda, assignment or
other instruments required by this Agreement, law or local custom or otherwise
reasonably requested by the other party to effect the transactions contemplated
by this Agreement and shall take such other actions (but at no material cost or
expense) as are reasonably requested by the other party to effect the
transactions contemplated by this Agreement.

         SECTION 6.6 Cooperation in Exchange. The parties acknowledge and agree
that Exchangors have elected (with respect to the Exchange Properties) and Buyer
may elect (with respect to the Properties) to assign their interest in this
Agreement to an exchange facilitator by means of one or more escrows for the
purpose of completing an exchange of such Properties or interests in such
Properties in a transaction which will qualify for treatment as a tax deferred
exchange pursuant to the provisions of Section 1031 of the Internal Revenue Code
of 1986 and applicable state revenue and taxation code sections (a "1031
Exchange"). Each party agrees to reasonably cooperate with any party so electing
in implementing any such assignment and 1031 Exchange, provided that such
cooperation shall not entail any material additional expense to the non-electing
party, cause such party to take title to any other property or cause such party
exposure to any liability or loss of rights or benefits contemplated by this
Agreement, and the electing party shall indemnify, defend and hold the
non-electing party harmless from any liability, damage, loss, cost or other
expense including, without limitation, reasonable attorneys' fees and costs,
resulting or arising from the implementation of any such assignment and 1031
Exchange. No such assignment by any party shall relieve such party from any of
its obligations





                                       36
<PAGE>   40

hereunder, nor shall such party's ability to consummate a tax deferred exchange
be a condition to the performance of such party's obligations under this
Agreement.

         SECTION 6.7 Environmental Matters.

                 (a) Buyer and Transferors acknowledge and agree that
Transferors shall transfer and assign to Buyer at the closing (to the extent
assignable), as part of the Intangible Property, Transferors' rights and
interests in and to any indemnifications or covenants from third parties (other
than any rights of Transferors under any of Transferors' environmental insurance
policies, which rights are expressly not assigned to Buyer under this Agreement)
relating to the environmental condition of the Properties (reserving solely
Transferors' rights to the benefit of such indemnifications and covenants
protecting Transferors with respect to Transferors' ownership of the
Properties), including, without limitation, those indemnity agreements shown on
Exhibit O. Following the closing, Buyer and Transferors shall cooperate in the
pursuit of any and all claims arising under such instruments, which cooperation
shall include, as required, Transferors' expression and pursuit of claims for
the benefit of Buyer -- provided that such pursuit is at Buyer's sole cost and
expense and does not expose Transferors to additional liability.

                 (b) With respect to the Property described on Exhibit U-1,
Transferors shall use reasonable efforts to obtain on or before closing (but
without any liability whatsoever if they are unable to do so except as set forth
below), a no further action letter (which letter shall be permitted to contain
customary qualifications and exclusions, such as a right of the lead regulatory
agency to reopen its investigation based on additional information, and may be a
risk based no further action letter) from the lead regulatory agency in
connection with the known contamination located on such Property as more
particularly described on Exhibit U-1 (an "NFA letter"). If Transferors are not
able to deliver to Buyer an NFA Letter with respect to any such Property on or
before the closing, then Transferors shall execute and deliver to Buyer at
closing with respect to any such Property as to which no NFA Letter has been
obtained, a remediation and access agreement in the form attached as Exhibit U-2
(the "Remediation and Access Agreement").

         SECTION 6.8 Environmental Insurance Deductibles. The parties hereto
acknowledge that Buyer intends to obtain environmental insurance ("Environmental
Insurance") for the Properties listed on Exhibit Q attached hereto (the "Insured
Properties"). If a loss occurs under the Environmental Insurance and to the
extent such loss is a result of environmental contamination or a release of
Hazardous Materials determined to have been present or to have occurred at an
Insured Property on or before the Closing Date (a "Loss"), then Transferors
shall reimburse to Buyer eighty percent (80%) of any amounts actually incurred
by Buyer with respect to such Loss (as substantiated by written invoices or
other evidence reasonably satisfactory to Transferors) as a result of the
application of the deductible under the Environmental Insurance for such Insured
Property, but in no event shall Transferors' liability exceed eighty thousand
dollars ($80,000) in the aggregate with respect to all Losses at any one Insured
Property. Buyer agrees not to take any affirmative actions which would or could
reasonably be expected to result in a Loss, such as performing a Phase II
environmental assessment, unless required to do so in writing by a lender,
rating agency, new material equity investor, a governmental authority or tenant
(but with respect to any of the foregoing persons, only after Buyer has used
commercially





                                       37
<PAGE>   41

reasonable efforts to find a suitable alternative to taking any such affirmative
actions, such as naming such party as an additional insured under Buyer's
environmental insurance policy or providing such party with an environmental
indemnity) or based on a reasonable belief that a release of Hazardous Materials
(other than with respect to a matter disclosed in the environmental reports
included in the Disclosure Materials) has occurred (provided, that the mere
existence of a dry cleaner at the Property is not in and of itself sufficient to
constitute such a "reasonable belief"), and in any event will not do so without
providing Transferors at least ten (10) days prior written notice to review the
scope of such action; provided, that the foregoing prohibition on Buyer taking
affirmative actions shall not apply with respect to a Property from and after
the two (2) year anniversary of the Closing Date for such Property. The
obligation of Transferors to reimburse Buyer under this Section 6.8 shall apply
only to Losses for a particular Property as to which Transferors receive written
notice from Buyer on or before the two (2) year anniversary of the Closing Date
for such Property.

         SECTION 6.9 Completion Events.

                 (a) With respect to the Property described on Exhibit R
attached hereto, on or before the closing, Transferors shall trigger Carl's
Junior's right to exercise its purchase option and concurrently therewith
Transferors shall use commercially reasonable efforts, but at no out of pocket
cost to Transferors, to either (i) cause the Title Company to insure over any
exception for Carl's Junior's purchase option to acquire such Property pursuant
to an endorsement or other affirmative coverage in form reasonably satisfactory
to Buyer or (ii) obtain a waiver of such right from Carl's Junior in form
reasonably acceptable to the Buyer. If, by the closing, Transferors are unable
to obtain either (i) or (ii) or Carl's Junior exercises its purchase option and
closes on such purchase, then such Property shall be treated as a Deleted
Property; provided, that if Carl's Junior has not exercised its purchase option
and closed on such purchase, Transferors shall be entitled to defer the closing
for such Property for a period of up to one (1) year to allow Transferors to
deliver title to such Property unencumbered by such purchase option, in which
event (i) the Price payable on the Closing Date applicable to all other
Properties shall be reduced by the Allocated Price of such Property, and (ii) an
amount equal to five percent (5%) of the Allocated Price for such Property shall
be retained by Title Company as a continuing Deposit subject to disposition in
accordance with Section 5.1 above as to such Property.

                 (b) General Provisions. All work performed by Transferors under
this Section 6.9 shall be performed in a good and workmanlike manner
substantially in accordance with all applicable laws. Nothing in this Section
6.9 is intended to limit or expand Buyer's approval rights contained in Section
4.2(c) or (d).

         SECTION 6.10 Transferors' Covenant of Cooperation. Transferors hereby
agree to reasonably cooperate with Buyer or Buyer's auditors, at no expense,
liability or substantial accounting time to Transferors, prior to and after the
closing (but subject to the provisions of Section 2.4) (i) by providing
financial data pertaining to the Properties to the extent required by the
Securities and Exchange Commission ("SEC") or reasonably required to prepare
filings that Buyer intends to file with the SEC, including (to the extent so
required) the documentation requested on Exhibit T-1 (but without duplication of
any of the documents listed in the Disclosure Material List & Statement or
contained in the Disclosure Materials so long as continued access is provided to
such documents as were not delivered to Buyer) as it relates to





                                       38
<PAGE>   42

the one (1) year period immediately preceding the closing, and (ii) in
delivering to Buyer's auditors a certificate in the form of Exhibit T-2.
Transferors shall provide such documentation and deliver such certificate in
each instance within ten (10) business days after receipt of Buyer's reasonable
request to do so. Without limiting Transferors' representations and warranties
contained in this Agreement or Transferors' covenants contained in Section 4.2
or in any document executed and delivered to Buyer by Transferors at closing,
Buyer shall indemnify and hold Transferors harmless from and against any and all
claims, liabilities, losses, damages, causes of action, costs and expenses
(including, without limitation, reasonable attorneys' fees and costs) to the
extent relating to or arising out of Transferors' performance of its obligations
under this Section 6.10, including, without limitation, any claims arising out
of the reliance by third parties, including Buyer's auditors, on information
provided by Transferors under this Section 6.10. The provisions of this Section
6.10 shall survive the closing

         SECTION 6.11 UCC Financing Statements. If Buyer provides evidence
during the Confirmation Period of any UCC Financing Statements naming a
Transferor or any of its affiliates as debtor and encumbering a Property
(whether in connection with mortgages, deeds of trust or personal property
financings which are not assumed by Buyer), then Transferors shall use
reasonable efforts to cause the release of such UCC Financing Statements as soon
as practicable after the closing.


                                    ARTICLE 7
                                  MISCELLANEOUS

         SECTION 7.1 Damage or Destruction.

                 (a) Buyer shall be bound to purchase each of the Properties as
required by the terms of this Agreement without regard to the occurrence or
effect of any damage to or destruction of any of the Properties or condemnation
of any Property by right of eminent domain, provided that the occurrence of any
damage or destruction involves repair costs of less than the greater of
$1,000,000 or ten percent (10%) of the Property's Allocated Price, and any
condemnation does not materially affect the use or value of the affected
Property. If Buyer is so bound to purchase a Property notwithstanding the
occurrence of damage, destruction or condemnation, or if Buyer fails to elect to
treat the applicable Property as a Deleted Property pursuant to Section 7.1(b)
below then upon the closing: (i) in the event of damage covered by insurance or
an immaterial condemnation, Buyer shall receive a credit against the Allocated
Price for such Property in the amount (net of collection costs and costs of
repair reasonably incurred by Transferors and not then reimbursed) of any
insurance proceeds or condemnation award collected and retained by Transferors
as a result of any such damage or destruction or condemnation plus (in the case
of damage) the amount of the deductible portion of Transferors' insurance
policy, and Transferors shall assign to Buyer all rights to such net insurance
proceeds or condemnation awards as shall not have been collected prior to the
close of escrow; and (ii) in the event of damage not covered by insurance, Buyer
shall receive a credit (not to exceed the greater of $1,000,000 or ten percent
(10%) of the Property's Allocated Price for each affected Property) in the
amount of the estimated cost to repair the damage.

                 (b) If, prior to the Closing Date, any Property suffers damage
or destruction that involves repair costs in excess of the greater of $1,000,000
or ten percent (10%) of the





                                       39
<PAGE>   43

Property's Allocated Price or condemnation which affects the use or value of the
Property in other than a minor and immaterial manner, then Buyer may elect to
treat such Property as a Deleted Property by giving written notice of such
election to Transferors promptly following Buyer's knowledge of the event and
extent of damage, destruction or condemnation. In the event of the deletion of
any Property pursuant to this Section 7.1(b), the parties shall be bound to
consummate the purchase and sale of the balance of the Properties in accordance
with this Agreement and the Price shall be reduced by an amount equal to the
Allocated Price of the Deleted Property.

         SECTION 7.2 Fees & Commissions.

                 (a) Each party to this Agreement warrants to the other that,
except as otherwise provided in subparagraph (b) below, no person or entity can
properly claim a right to a real estate or investment banker's commission,
finder's fee, acquisition fee or other brokerage-type compensation
(collectively, "Real Estate Compensation") based upon the acts of that party
with respect to the transaction contemplated by this Agreement. Each party
hereby agrees to indemnify and defend the other against and to hold the other
harmless from any and all loss, cost, liability or expense (including but not
limited to attorneys' fees and returned commissions) resulting from any claim
for Real Estate Compensation by any person or entity based upon such acts.

                 (b) The parties hereby acknowledge that Morgan Stanley Dean
Witter has acted as Transferors' investment bankers in connection with this
transaction. Transferors shall be responsible for paying any commission or fees
due to such parties in connection with this transaction.

         SECTION 7.3 Successors and Assigns. Buyer may not assign any of Buyer's
rights or duties hereunder without the prior written consent of Transferors,
which may be withheld in Transferors' sole discretion; provided, however, that
Buyer shall have the right to assign all or a portion of its rights hereunder to
an entity which is at least 75% owned, directly or indirectly, by Buyer, without
the prior consent of Transferors, except that any such assignment to such an
affiliate of Buyer shall not relieve Buyer of any of its obligations under this
Agreement.

         SECTION 7.4 Notices. Any notice, consent or approval (or request for
consent or approval) required or permitted to be given under this Agreement
shall be in writing and shall be given or requested by (i) hand delivery, (ii)
Federal Express or another reliable overnight courier service, (iii) facsimile
telecopy, or (iv) United States mail, registered or certified mail, postage

Deposit to Title Company, the parties shall issue a joint press release with
respect to this transaction, which press release shall be in the form attached

prevent Buyer from disclosing any information otherwise deemed confidential

liability under this Agreement.

         SECTION 7.17 Escrow Provisions.

                 (a) By its signature below, Title Company acknowledges receipt
of the Deposit (whether in the form of cash or a Letter of Credit). Title
Company agrees to hold the Deposit (whether in the form of cash or a Letter of
Credit) in escrow pursuant to the provisions of this Agreement for application
in accordance with the provisions of this Agreement, including the following
terms:

                     (1) Title Company shall have no duties or responsibilities
other than those expressly set forth in this Agreement. Title Company shall have
no duty to enforce any obligation of any person to make any payment or delivery
or to enforce any obligation of any person to perform any other act. Title
Company shall be under no liability to the other parties





                                       44
<PAGE>   48

hereto or to anyone else by reason of any failure on the part of any party
hereto or any maker, guarantor, endorser or other signatory of any document or
any other person to perform such person's obligations under any such document.
Except for this Agreement, amendments to this Agreement executed by Transferors
and Buyer and except for joint written instructions given to Title Company by
Transferors and Buyer relating to the Deposit, Title Company shall not be
obligated to recognize any agreement between any or all of the persons referred
to herein, notwithstanding that references thereto may be made herein and
whether or not it has knowledge thereof.

                     (2) In its capacity as Title Company, Title Company shall
not be responsible for the genuineness or validity of any security, instrument,
document or item deposited with it and shall have no responsibility other than
to faithfully follow the instructions contained in this Agreement, and subject
to the terms hereof, it is fully protected in acting in accordance with any
written instrument given to it hereunder by any of the parties hereto and
believed by Title Company to have been signed by the proper person. Title
Company may assume that any person purporting to give any notice hereunder has
been duly authorized to do so. Title Company is acting as a stakeholder only
with respect to the Deposit. If there is any dispute or uncertainty concerning
any action to be taken hereunder, Title Company shall have the right to take no
action (other than to make demand for the principal amount of any portion of the
Deposit in the form of a Letter of Credit as may be required under this
Agreement which demand shall be made as so required by this Agreement
notwithstanding any contrary instructions by Buyer unless approved in writing by
Transferors) until it shall have received instructions in writing approved by
Transferors and Buyer or until directed by a final order of judgment of a court
of competent jurisdiction, whereupon Title Company shall take such action in
accordance with such instructions or such order.

                     (3) It is understood and agreed that the duties of Title
Company are purely ministerial in nature. Title Company shall not be liable to
the other parties hereto or to anyone else for any action taken or omitted by
it, or any action suffered by it to be taken or omitted, in good faith and in
the exercise of reasonable judgment, except for acts of willful misconduct or
gross negligence. Title Company may rely conclusively and shall be protected in
acting upon any order, notice, demand, certificate, opinion or advice of counsel
(including counsel chosen by Title Company), statement, instrument, report or
other paper or document (not only as to its due execution and the validity and
effectiveness of its provisions, but also as to the truth and accuracy of any
information therein contained) which is reasonably believed by Title Company to
be genuine and signed or presented by the proper person or persons. Title
Company shall not be bound by any notice or demand, or any waiver, modification,
termination or rescission of this Agreement or any of the terms hereof, unless
evidenced by a final judgment or decree of a court of competent jurisdiction in
the State of California or a Federal court in such State, or a writing delivered
to Title Company signed by the proper party or parties and, if the duties or
rights of Title Company are affected, unless it shall give its prior written
consent thereto.

                     (4) Title Company shall have the right to assume in the
absence of written notice to the contrary from the proper person or persons that
a fact or an event by reason of which an action would or might be taken by Title
Company does not exist or has not occurred, without incurring liability to the
other parties hereto or to anyone else for any action taken or





                                       45
<PAGE>   49

omitted, or any action suffered by it to be taken or omitted, in good faith and
in the exercise of reasonable judgment, in reliance upon such assumption.

                     (5) Except in connection with Title Company's willful
misconduct or gross negligence, Title Company shall be indemnified and held
harmless jointly and severally by the other parties hereto from and against any
and all liabilities, expenses and losses suffered by Title Company (as escrow
agent), including reasonable attorneys' fees and expenses, in connection with
any action, suit or other proceeding involving any claim, which arises out of or
relates to this Agreement, the services of Title Company hereunder or the monies
or instruments held by it hereunder. Promptly after the receipt by Title Company
of notice of any demand or claim or the commencement of any action, suit or
proceeding, Title Company shall, if a demand or a claim is made or an action is
commenced against any of the other parties hereto, notify such other parties
hereto in writing; but the failure by Title Company to give such notice shall
not relieve any party from any liability which such party may have to Title
Company hereunder.

                     (iii) Buyer is hereby apprised of and shall determine
