Exhibit 10.2

REIMBURSEMENT AGREEMENT

     THIS REIMBURSEMENT AGREEMENT (this “Reimbursement Agreement”) is entered into this 20 day of
July, 2006, by and between Hines Interests Limited Partnership, a Delaware limited partnership
(“HILP”), and Hines Real Estate Investment Trust, Inc., a Maryland corporation (“Company”).

RECITALS:

     A. The Company has entered into a Selected Dealer Agreement, dated July 20, 2006 (the
“Selected Dealer Agreement”), with Ameriprise Financial Services, Inc. (“Ameriprise”), Hines
Advisors Limited Partnership, a Texas limited partnership (“HALP”) and Hines Real Estate
Securities, Inc., a Delaware corporation (“HRES”) pursuant to which Ameriprise will offer and sell
on a best efforts basis for the account of the Company shares of the Company’s common stock on the
terms set forth in the Selected Dealer Agreement.

     B. In connection with the Selected Dealer Agreement, the Company, HALP and HRES have agreed to
indemnify and hold harmless (or in cases in which indemnification is unavailable, to make
contribution) Ameriprise and each person who controls Ameriprise within the meaning of Section 15
of the Securities Act of 1933, as amended, and any of their respective officers, directors,
employees and agents against losses, liabilities, claims, damages and expenses as set forth in the
Selected Dealer Agreement (the “SDA Indemnities”).

     C. Likewise, in connection with the Selected Dealer Agreement, HILP agreed to be jointly and
severally liable with the Company, HALP and HRES under the SDA Indemnities up to a maximum amount
of the lesser of $40,000,000 or 10% of the gross proceeds raised by Ameriprise for the Company
under the Selected Dealer Agreement.

     D. HILP and the Company desire to reflect their agreement among themselves regarding how
obligations pursuant to the SDA Indemnities will be shared.

     NOW THEREFORE, HILP and the Company hereby agree as follows:

     1. Indemnity and Reimbursement Obligation.

	 	(a)	 	The Company hereby agrees to indemnify and hold HILP harmless from all
amounts which HILP has or may incur or become liable for as a result of or
in connection with the SDA Indemnities, including the costs and expenses
described in Section 1(b) of this Reimbursement Agreement (the
“Obligations”). If HILP is required to pay any Obligations, HILP will be
reimbursed by the Company in accordance with this Reimbursement Agreement.
	 
	 	(b)	 	The Company agrees to pay to HILP all reasonable costs and expenses
incurred by it in connection with (i) the preparation, execution and
delivery of this Reimbursement Agreement and the Selected Dealer Agreement
and any other documents which may be delivered in connection with this
Agreement or the Selected Dealer Agreement, and

1

 

	 	 	 	(ii) the enforcement by any person or entity of the SDA Indemnities or any
other provision of the Selected Dealer Agreement (or any agreements related
thereto to which HILP is a party), which (for both clauses (i) and (ii)
above) amounts will include all court costs, attorneys’ fees, fees of
auditors and accountants and investigation expenses reasonably incurred by
HILP in connection with any such matters.
	 
	 	(c)	 	Any reimbursement provided for herein to HILP shall be due and payable
within 10 days of notice to the Company that HILP has made payments in
satisfaction of any Obligations, which notice shall include reasonable
evidence that such payment or payments have been made. Any payment not made
by the Company to HILP hereunder within 10 days of the date such payment
first comes due shall bear interest from the date due until paid at the rate
of the lesser of (i) the prime rate plus five percentage points, or (ii) the
maximum rate allowed by law.
	 
	 	(d)	 	Subject only to the limitations contained in Section 12.2(b) of the
Company’s Amended and Restated Articles of Incorporation that relate to the
Company’s ability to provide indemnification for certain losses arising from
or out of alleged violations of federal or state securities laws (which
limitations shall for purposes of this Agreement be deemed to apply to
indemnification of HILP by the Company pursuant to this Reimbursement
Agreement as though HILP was an “Indemnitee” under such section), the
obligations of the Company under this Reimbursement Agreement are absolute,
unconditional and irrevocable and shall be paid and observed, as may be
applicable, strictly in accordance with the terms of this Reimbursement
Agreement under all circumstances whatsoever, including the following
circumstances: (i) any lack of validity or enforceability of any provision
of the Selected Dealer Agreement; (ii) any amendment or waiver of or any
consent to departure from any provision of the Selected Dealer Agreement;
(iii) the existence of any claim, setoff, defense or other right which the
Company may have at any time against Ameriprise or any person or entity,
whether in connection with this Reimbursement Agreement, the transactions
contemplated herein or in the Selected Dealer Agreement or any unrelated
transactions; or (iv) any other circumstances or happening whatsoever,
whether or not similar to any of the foregoing.
	 
	 	(e)	 	In the event of a default by the Company hereunder, HILP shall have all
remedies available at law or in equity. In addition, the rights granted
HILP pursuant to this Reimbursement Agreement are not the exclusive remedies
available to HILP in connection with the Obligations or actions related
thereto, and HILP shall have all other remedies available to it at law or in
equity.
	 
	 	(f)	 	Subject to the limitations and exceptions set forth in this Section 1
and in order to provide for just and equitable contribution where (and only
to the extent) the reimbursement and indemnification provided for in this

2

 

	 	 	 	Section 1 is unavailable or insufficient for any reason to hold harmless
HILP for any Obligations, the Company shall contribute to the amount paid,
payable or incurred by HILP as a result of such Obligations in such
proportion as is appropriate to reflect the relative benefits received by
the Company and HILP from the transactions contemplated by the Selected
Dealer Agreement, based on proceeds received by the Company as a result of
the shares sold under the Selected Dealer Agreement compared to the property
management and leasing fees received by HILP as a result of real estate
investments acquired by the Company and managed by HILP as a result of
proceeds received from the sale of such shares. If, however, the allocation
provided by the immediately preceding sentence is not permitted by
applicable law, then the Company, in lieu of indemnifying HILP, shall
contribute to the amount paid, payable or incurred by HILP in such
proportion as is appropriate to reflect not only such relative benefits
referred to above but also the relative fault of the Company and HILP in
connection with the actions which resulted in such Obligations (or actions
in respect thereof), as well as any other relevant equitable considerations.
In no event shall the amount of HILP’s contribution to the Obligations
exceed the property management and leasing fees received by HILP or any of
its affiliates as a result of real estate investments acquired by the
Company (and managed by HILP or any of its affiliates) from the proceeds of
the shares sold pursuant to the Selected Dealer Agreement.

     2. Notices. All notices, demands, consents, approvals, requests or other
communications which any of the parties to this Reimbursement Agreement may desire or be required
to give hereunder shall be in writing and shall be sent by registered or certified mail, postage

Contingency Period except as otherwise expressly provided herein.

               (2) If Buyer delivers a waiver notice under Section 2.2 to Seller prior to the expiration of
the Contingency Period, on or before September 15, 2006, Buyer shall deposit in escrow with the
Title Company an additional amount of Ten Million Dollars ($10,000,000) (the “Additional Deposit”)
in cash or other immediately available funds prior to the expiration of the Contingency Period.
The Initial Deposit and the Additional Deposit (if and when the Additional Deposit is deposited by

2

 

fully earned by Seller as consideration for entering into the Agreement and shall be
nonrefundable after the Contingency Period except as otherwise expressly provided herein.

     The Deposit shall be held in an interest bearing account and all interest thereon, less
investment fees, if any, shall be deemed a part of the Deposit for all purposes hereunder. If the
sale of the Property as contemplated hereunder is consummated, then the Deposit shall be paid to
Seller at the Closing (as defined in Section 1.2(b)(3) below) and credited against the Purchase
Price. IF THE SALE OF THE PROPERTY IS NOT CONSUMMATED DUE TO SELLER’S DEFAULT HEREUNDER, THEN
BUYER MAY ELECT, AS BUYER’S SOLE AND EXCLUSIVE REMEDY, EITHER TO: (1) TERMINATE THIS AGREEMENT AND
RECEIVE A REFUND OF THE DEPOSIT, IN WHICH EVENT NEITHER PARTY SHALL HAVE ANY FURTHER RIGHTS OR
OBLIGATIONS HEREUNDER EXCEPT AS PROVIDED IN SECTIONS 6.1, 9.3 AND 9.9 BELOW (PROVIDED, HOWEVER,
THAT IN THE EVENT THAT SUCH SELLER DEFAULT IS AN INTENTIONAL, WILLFUL BREACH OF THIS AGREEMENT BY
SELLER, BUYER SHALL ALSO BE ENTITLED TO REIMBURSEMENT FOR ACTUAL THIRD-PARTY OUT-OF-POCKET COSTS

AMOUNT UP TO, BUT NOT TO EXCEED, TWO HUNDRED THOUSAND DOLLARS ($200,000)), OR (2) ENFORCE SPECIFIC
PERFORMANCE OF THIS AGREEMENT. BUYER SHALL NOT HAVE ANY OTHER RIGHTS OR REMEDIES HEREUNDER AS A
RESULT OF ANY DEFAULT BY SELLER PRIOR TO CLOSING, AND BUYER HEREBY WAIVES ANY OTHER SUCH REMEDY AS
A RESULT OF A DEFAULT HEREUNDER BY SELLER PRIOR TO CLOSING. IF THE SALE IS NOT CONSUMMATED DUE TO
ANY DEFAULT BY BUYER HEREUNDER, THEN SELLER SHALL, AS SELLER’S SOLE AND EXCLUSIVE REMEDY, RETAIN
THE DEPOSIT AS LIQUIDATED DAMAGES. THE PARTIES HAVE AGREED THAT SELLER’S ACTUAL DAMAGES, IN THE
EVENT OF A FAILURE TO CONSUMMATE THIS SALE DUE TO BUYER’S DEFAULT PRIOR TO CLOSING, WOULD BE
EXTREMELY DIFFICULT OR IMPRACTICABLE TO DETERMINE. AFTER NEGOTIATION, THE PARTIES HAVE AGREED
THAT, CONSIDERING ALL THE CIRCUMSTANCES EXISTING ON THE DATE OF THIS AGREEMENT, THE AMOUNT OF THE
DEPOSIT IS A REASONABLE ESTIMATE OF THE DAMAGES THAT SELLER WOULD INCUR IN SUCH EVENT. BY PLACING
THEIR INITIALS BELOW, EACH PARTY SPECIFICALLY CONFIRMS THE ACCURACY OF THE STATEMENTS MADE ABOVE
AND THE FACT THAT EACH PARTY WAS REPRESENTED BY COUNSEL WHO EXPLAINED, AT THE TIME THIS AGREEMENT
WAS MADE, THE CONSEQUENCES OF THIS LIQUIDATED DAMAGES PROVISION. THE FOREGOING IS NOT INTENDED TO
LIMIT BUYER’S OBLIGATIONS UNDER SECTIONS 6.1, 9.3 AND 9.9.

INITIALS:           SELLER                                 BUYER

in which it was formed, and, if so required to, is qualified to do business in the state in which
the Real Property is located.

          (i) Seller is in compliance with all laws, statutes, rules and regulations or any federal,
state or local governmental authority in the United States of America applicable to Seller and to
Seller’s knowledge, all beneficial owners of Seller with respect to or arising out of the
requirements of Executive Order No. 13224, 66 Fed Reg. 49079 (September 23, 2001) (the “Order”) and
other similar requirements contained in the rules and regulations of the Office of Foreign Asset
Control, Department of the Treasury (“OFAC”) and in any enabling legislation or other Executive
Orders in respect thereof (the Order and such other rules, regulations, legislation, or orders are
collectively called the “Orders”).

          (j) Seller is not a party in interest with respect to any employee benefit or other plan
within the meaning of Section 3(3) of the Employee Retirement Income Security Act of 1974, as
amended (“ERISA”), or of Section 4975(e)(1) of the Code, which is subject to ERISA or Section 4975
of the Code and which is an investor in Buyer.

          (k) To the best of Seller’s knowledge, Seller has received no written notice from any
insurance company or board of fire underwriters of any defects in or on the Property that would
adversely affect the insurability of the Property or cause any increase in the premiums for
insurance for the Property.

     Each of the representations and warranties of Seller contained in this Section 3.1: (1) shall
be true in all material respects as of the date of Closing, subject in each case to (A) any
Exception Matters (as defined below), (B) the Disclosure Items, and (C) other matters expressly
permitted in this Agreement or otherwise specifically approved in writing; and (2) shall survive
the Closing as provided in Section 3.3 below.

     Section 3.2 No Liability for Exception Matters.

     As used herein, the term “Exception Matter” shall refer to a matter which would make a
representation or warranty of Seller contained in this Agreement untrue or incorrect and which is
disclosed to Buyer in the Due Diligence Materials, the Disclosure Items or is a matter of public
record, or is otherwise discovered by Buyer before the Closing, including, without limitation,
matters disclosed in any tenant estoppel certificate or from interviews with tenants, property
managers or any other person. If Buyer first obtains knowledge of any material Exception Matter
after the close of the Contingency Period and prior to Closing and such Exception Matter was not
contained in the Due Diligence Materials, the Disclosure Items or is not a matter of public record,
Buyer’s sole remedy shall be to terminate this Agreement on the basis thereof, upon written notice
to Seller within the earlier of (a) five (5) days following Buyer’s discovery of such Exception
Matter or (b) the Closing, which ever occurs first, in which event the Deposit shall be returned to
Buyer, unless within five (5) days after receipt of such notice or by the Closing, as the case may
be, Seller notifies Buyer in writing that it elects to attempt to cure or remedy such Exception
Matter, in which event there shall be no return of the Deposit unless and until Seller is unable to
so cure or remedy within the time period set forth below. Seller shall be entitled to extend the
Closing Date for up to fifteen (15) business days in order to attempt to cure

7

 

or remedy any Exception Matter. Buyer’s failure to give notice within five (5) days after it
has obtained knowledge of a material Exception Matter prior to Closing shall be deemed a waiver by
Buyer of such Exception Matter. Seller shall have no obligation to cure or remedy any Exception
Matter, even if Seller has notified Buyer of Seller’s election to attempt to cure or remedy any
Exception Matter (except as specifically provided in Section 4.1(c) hereof), and, subject to
Buyer’s right to terminate this Agreement as set forth above, Seller shall have no liability
whatsoever to Buyer with respect to any Exception Matters. Upon any termination of this Agreement,
neither party shall have any further rights nor obligations hereunder, except as provided in
Sections 6.1, 9.3 and 9.9 below. If Buyer obtains knowledge of any Exception Matter before the
Closing, but nonetheless elects to proceed with the acquisition of the Property, Seller shall have
no liability with respect to such Exception Matter, notwithstanding any contrary provision,
covenant, representation or warranty contained in this Agreement or in any Other Documents (as
defined in Section 9.19 below).

     Section 3.3 Survival of Seller’s Representations and Warranties of Sale.

     The representations and warranties of Seller contained herein or in any Seller estoppel
delivered pursuant to Section 8.4 below, or in any Other Documents, shall survive for a period of
nine (9) months after the Closing. Any claim which Buyer may have against Seller for a breach of
any such representation or warranty, whether such breach is known or unknown, which is not
specifically asserted by written notice to Seller within such nine (9) month period shall not be
valid or effective, and Seller shall have no liability with respect thereto.

     Section 3.4 Seller’s Knowledge.

     For purposes of this Agreement and any document delivered at Closing, whenever the phrase “to
the best of Seller’s knowledge” or the “knowledge” of Seller or words of similar import are used,
they shall be deemed to mean and are limited to the current actual knowledge only of Craig Davey,
Karen Saitta and Tom Schienbein at the times indicated only, and not any implied, imputed or
constructive knowledge of such individual(s) or of Seller or any Seller Related Parties (as defined
in Section 3.7 below), and without any independent investigation or inquiry having been made or any
implied duty to investigate, make any inquiries or review the Due Diligence Materials.
Furthermore, it is understood and agreed that such individual(s) shall have no personal liability
in any manner whatsoever hereunder or otherwise related to the transactions contemplated hereby.

     Section 3.5 Representations and Warranties of Buyer.

     Buyer represents and warrants to Seller as follows:

for a period of nine (9) months after the Closing. Any claim which Seller may have against Buyer
for a breach of any such representation or warranty (excluding the representation and warranty
contained in Section 3.5(g)), whether such breach is known or unknown, which is not specifically
asserted by written notice to Buyer within such nine (9) month period shall not be valid or
effective, and Buyer shall have no liability with respect thereto.

Buyer’s sole expense. For purposes of this Agreement, “Hazardous Materials” shall mean inflammable
explosives, radioactive materials, asbestos, asbestos–containing materials, polychlorinated

in connection with the transaction contemplated hereby. Buyer acknowledges and agrees that all
materials, data and information delivered by Seller to Buyer in connection with the transaction
contemplated hereby are provided to Buyer as a convenience only and that any reliance on or use of
such materials, data or information by Buyer shall be at the sole risk of Buyer, except as
otherwise expressly stated herein. Without limiting the generality of the foregoing provisions,
Buyer acknowledges and agrees that (a) any environmental or other report with respect to the
Property which is delivered by Seller to Buyer shall be for general informational purposes only,

10

 

Property, including any proposal for work at the Property which was not performed by Seller,
shall not be actionable by Buyer under this Agreement or otherwise.

          (c) EXCEPT AS EXPRESSLY SET FORTH IN SECTION 3.1 ABOVE, BUYER SPECIFICALLY ACKNOWLEDGES AND
AGREES THAT SELLER IS SELLING AND BUYER IS PURCHASING THE PROPERTY ON AN “AS IS WITH ALL FAULTS”
BASIS AND THAT, EXCEPT FOR THE REPRESENTATIONS AND WARRANTIES AS EXPRESSLY SET FORTH IN SECTION 3.1

     Section 3.7 Release.

          (a) Without limiting the above, and subject to (y) the representations and warranties of
Seller contained in Section 3.1 hereof, and (z) Seller’s express covenants (1) contained herein
which expressly survive the Closing hereunder, or (2) contained in the Closing Documents which

right to recover from, and forever releases and discharges, Seller, Seller’s affiliates, Seller’s

Buyer arising from the period during Seller’s ownership of the Property which were not caused by
Buyer’s actions and/or inactions. Nothing contained in this Section 3.7(a) shall be construed to
limit Buyer’s right to implead Seller into any lawsuit in which Buyer has been named by a third

result of a release of Hazardous Materials at the Real Property directly caused by Seller during

          (b) Buyer further hereby assumes the risk of changes in applicable laws and regulations
relating to past, present and future environmental, safety or health conditions on, or resulting

ARTICLE IV

TITLE

     Section 4.1 Conditions of Title.

          (a) Upon execution of this Agreement, Seller shall order an updated preliminary title report
or commitment (the “Title Report”) from the Title Company, which shall be delivered to Buyer,
together with copies of all underlying documents relating to title exceptions referred to therein,
promptly upon Seller’s receipt thereof. Seller shall also furnish to Buyer within the Delivery
Period any existing survey of the Property in Seller’s possession. Buyer shall immediately order
any plat or survey of the Property or any update thereto from a duly licensed surveyor (the
“Survey”) if desired by Buyer or if necessary to support the issuance of the Title Policy (as
defined in Section 4.2 below). Buyer shall provide to Seller a copy of the Survey, which shall be
certified to the Title Company, Buyer and Seller. Buyer shall pay the entire cost of the Survey.
If Closing does not occur, Buyer shall, if Seller so requests, assign to Seller all contract rights
Buyer has with the surveyor and in such event Seller shall reimburse Buyer for the cost of the
Survey.

          (b) On or before the expiration of the Contingency Period (the “Title Review Date”), Buyer
shall have the right to furnish Seller with a written statement of objections, if any, to the title
to the Property, including, without limitation, any objections to any matter shown on the Survey
(collectively, “Objections”), in which event this Agreement shall terminate, the Deposit shall be
returned to Buyer, and neither party hereto shall have any further rights or obligations hereunder
except as otherwise provided in Sections 6.1, 9.3 and 9.9 below. Should Buyer fail to notify
Seller in writing of any Objections to the Title Report prior to the Title Review Date, Buyer shall
be deemed to have approved such matters, which shall be considered to be “Conditions of Title”;
provided, however, that any and all Seller’s Liens (as defined below) shall in no event be deemed
to be Conditions of Title, and Seller shall cure or remove all such Seller’s Liens prior to Closing
regardless of whether Buyer objects thereto. In the event the Title Company amends or updates the
Title Report after the Title Review Date (each, a “Title Report Update”), Buyer shall furnish
Seller with a written statement of Objections to any matter first raised in a Title Report Update
within three (3) business days after its receipt of such Title Report Update (each, a “Title Update
Review Period”). Should Buyer fail to notify Seller in writing of any Objections to the Title
Report prior to the Title Review Date, or to any matter first disclosed in a Title Report Update
prior to the expiration of the applicable Title Update Review Period, as applicable, Buyer shall be
deemed to have approved such matters which shall be considered to be “Conditions of Title”;
provided, however, that any and all Seller’s Liens shall in no event be deemed to be Conditions of
Title and Seller shall cure or remove all such Seller’s Liens prior to Closing regardless of
whether Buyer objects thereto.

          (c) If Seller receives a timely Objection to anything first disclosed in a Title Report Update
in accordance with Section 4.1(b) (“Buyer’s Notice”), Seller shall have the right, but not the
obligation, within two (2) business days after receipt of Buyer’s Notice (“Seller’s Response
Period”), to elect to attempt to cure any such matter upon written notice to Buyer (“Seller’s
Response”), and may extend the Closing Date for up to fifteen (15) business days to allow such
cure. If Seller does not give any Seller’s Response, Seller shall be deemed to have

14

 

elected not to attempt to cure any such matters. Notwithstanding the foregoing, Seller shall
in any event be obligated to cure all matters or items (i) that are mortgage or deed of trust liens
or security interests against the Property, in each case granted by Seller (and not tenants of the
Property or other third parties), (ii) real estate tax liens, other than liens for taxes and
assessments not yet delinquent, (iii) that have been voluntarily placed against the Property by
Seller (and not tenants of the Property or other third parties) after the date of this Agreement
and that are not otherwise permitted pursuant to the provisions hereof and (iv) mechanics liens
arising out of construction contracts entered into by Seller and a contractor (collectively,
“Seller’s Liens”). Seller shall be entitled to apply the Purchase Price towards the payment or
satisfaction of such liens, and may cure any Objection by causing the Title Company to insure
against collection of the same out of the Property.

          (d) If Seller elects (or is deemed to have elected) not to attempt to cure any Objections
raised in any Buyer’s Notice timely delivered by Buyer to Seller pursuant to Section 4.1(b), or if
Seller notifies Buyer that it elects to attempt to cure any such Objection but then does not for
any reason effect such cure on or before the Closing Date as it may be extended hereunder, then
Buyer, as its sole and exclusive remedy, shall have the option of terminating this Agreement by
delivering written notice thereof to Seller within one (1) business day after (as applicable (i)
its receipt of Seller’s Response stating that Seller will not attempt to cure any such Objection or
(ii) the expiration of Seller’s Response Period if Seller does not deliver a Seller’s Response or
(iii) Seller’s failure to cure by the Closing Date (as it may be extended hereunder) any Objection
which Seller has previously elected to attempt to cure pursuant to a Seller’s Response. In the
event of such a termination, the Deposit shall be returned to Buyer, and neither party shall have
any further rights or obligations hereunder except as provided in Sections 6.1, 9.3 and 9.9 below.
If no such termination notice is timely received by Seller hereunder, Buyer shall be deemed to have
waived all such Objections (other than with respect to Seller’s Liens) in which event those
Objections shall become “Conditions of Title” under Section 4.1(e). If the Closing is not
consummated for any reason other than Seller’s default hereunder, Buyer shall be responsible for
any title or escrow cancellation charges.

          (e) At the Closing, Seller shall convey title to the Property to Buyer by deed in the form of
Exhibit C attached hereto (the “Deed”) subject to no exceptions other than:

               (1) Interests of tenants in possession, as tenants only, under the Leases;

               (2) Matters created by or with the written consent of Buyer;

               (3) Non-delinquent liens for real estate taxes and assessments; and

               (4) Any exceptions disclosed by the Title Report and any Title Report Update which is approved
or deemed approved by Buyer in accordance with this Article IV above, and any other exceptions to
title which would be disclosed by an inspection and/or survey of the Property.

All of the foregoing exceptions shall be referred to collectively as the “Conditions of Title.”
Subject to the terms and conditions contained elsewhere in this Agreement, by acceptance of the

15

 

Deed and the Closing of the purchase and sale of the Property, (x) Buyer agrees it is assuming for
the benefit of Seller all of the obligations of Seller with respect to the Conditions of Title from
and after the Closing, and (y) Buyer agrees that Seller shall have conclusively satisfied its
obligations with respect to title to the Property. The provisions of this Section shall survive
the Closing.

     Section 4.2 Evidence of Title.

     Delivery of title in accordance with the foregoing shall be evidenced by the willingness of
the Title Company to issue, at Closing, its Owner’s ALTA Policy of Title Insurance in the amount of
the Purchase Price showing title to the Real Property vested in Buyer, subject only to the
Conditions of Title (the “Title Policy”). The Title Policy may contain such endorsements as
reasonably required by Buyer provided that the issuance of such endorsements shall not be a
condition to Buyer’s obligations hereunder. Buyer shall pay the costs for all such endorsements.
Seller shall have no obligation to provide any indemnity or agreement to the Title Company or Buyer
to support the issuance of the Title Policy or any such endorsements other than an affidavit as to
the existing tenants of the Property and any ongoing construction work at the Property.

ARTICLE V

RISK OF LOSS AND INSURANCE PROCEEDS

     Section 5.1 Minor Loss.

     Buyer shall be bound to purchase the Property for the full Purchase Price as required by the
terms hereof, without regard to the occurrence or effect of any damage to the Property or
destruction of any improvements thereon or condemnation of any portion of the Property, provided
that: (a) the cost to repair any such damage or destruction does not exceed an amount equal to One
Million Dollars ($1,000,000) in the estimate of an architect or contractor selected by Seller and
reasonably acceptable to Buyer or in the case of a condemnation, the diminution in the value of the
remaining Property as a result of a partial condemnation is not material (as hereinafter defined),
(b) no Major Tenant (as such term is defined below) shall exercise its right to terminate its
respective Lease in connection with any such damage, destruction or condemnation, and (c) upon the
Closing, (i) if the cost of repairing the damage or casualty is insured, there shall be a credit
against the Purchase Price due hereunder equal to the amount of any insurance proceeds (including
all proceeds of loss of rents or business interruption insurance, if any, applicable to the period
after Closing) or condemnation awards collected by Seller as a result of any such damage or
destruction or condemnation, plus the amount of any applicable insurance deductible up to but not
to exceed One Million Dollars $1,000,000, or (ii) if the cost of repairing the damage or casualty
is not insured, there shall be a credit against the Purchase Price due hereunder equal to the
amount estimated by such architect or contractor as being required to fully repair and restore such
damage or destruction, (but in no event shall such amount exceed One Million Dollars ($1,000,000)),
in each case less any sums reasonably expended by Seller toward the collection of such proceeds or
awards, as applicable, and the restoration or repair of the Property (the nature of which
restoration or repairs, but not the right of Seller to effect such restoration or repairs, shall be
subject to the approval of Buyer, which approval shall not be

16

 

unreasonably withheld, conditioned or delayed). If the proceeds or awards have not been
collected as of the Closing, then such proceeds or awards shall be assigned to Buyer, except to the
extent needed to reimburse Seller for sums expended to collect such proceeds or awards or to repair
or restore the Property, and Seller shall retain the rights to such proceeds and awards to such
extent so reasonably expended.

     Section 5.2 Major Loss.

     If the cost to repair the damage or destruction as specified above exceeds an amount equal to
One Million Dollars ($1,000,000) in the estimate of an architect or contractor selected by Seller
and reasonably acceptable to Buyer or the diminution in the value of the remaining Property as a
result of a condemnation is material (as hereinafter defined), then Buyer may, at its option to be
exercised within five (5) days after receipt of Seller’s notice of the occurrence of the damage or
destruction or the commencement of condemnation proceedings (which notice must cite said
architect’s or contractor’s estimate of the cost of repairing such damage or destruction), either
terminate this Agreement or consummate the purchase for the full Purchase Price as required by the
terms hereof. If Buyer elects to terminate this Agreement by delivering written notice thereof to
Seller or fails to give Seller notice within such five (5) day period that Buyer will proceed with
the purchase, then this Agreement shall terminate, the Deposit shall be returned to Buyer and
neither party shall have any further rights or obligations hereunder except as provided in Sections
6.1, 9.3 and 9.9 below. If Buyer elects to proceed with the purchase, then upon the Closing, (i)
if the cost of repairing the damage or casualty is insured, there shall be a credit against the
Purchase Price due hereunder equal to the amount of any insurance proceeds (including all proceeds
of loss of rents or business interruption insurance, if any, applicable to the period after
Closing) or condemnation awards collected by Seller as a result of any such damage or destruction
or condemnation, plus the amount of any applicable insurance deductible up to but not to exceed One
Million Dollars ($1,000,000), or (ii) if the cost of repairing the damage or casualty is not
insured, there shall be a credit against the Purchase Price of One Million Dollars ($1,000,000), in
each case less any sums reasonably expended by Seller toward the collection of such proceeds or
awards, as applicable, or to restoration or repair of the Property (the nature of which
restoration or repairs, but not the right of Seller to effect such restoration or repairs, shall be
subject to the approval of Buyer, which approval shall not be unreasonably withheld, conditioned or
delayed). If the proceeds or awards have not been collected as of the Closing, then such proceeds
or awards shall be assigned to Buyer, except to the extent needed to reimburse Seller for sums
expended to collect such proceeds or awards or to repair or restore the Property, and Seller shall
retain the rights to such proceeds and awards to such extent so reasonably expended. A
condemnation shall be deemed material if any material portion of any net rentable area of the
Property or any material portion of the parking is taken, or the existing access to the Property is
materially and adversely affected, permanently.

ARTICLE VI

BROKERS AND EXPENSES

     Section 6.1 Brokers.

     The parties represent and warrant to each other that no broker or finder was instrumental in
arranging or bringing about this transaction except for Stephen M. Somer of Eastdil Secured
(“Seller’s Broker”). At Closing, Buyer shall pay Seller’s Broker One Million Five Hundred Fifty
Eight Thousand Four Hundred Eighty Dollars ($1,558,480), which amount equals the commission due to
Seller’s Broker, which shall be paid pursuant to the terms of a separate agreement between Buyer
and Seller’s Broker (the “Commission”). If any other person brings a claim for a commission or
finder’s fee based upon any contact, dealings or communication with Buyer or Seller, then the party
through whom such person makes his claim shall defend the other party (the “Indemnified Party”)
from such claim, and shall indemnify the Indemnified Party and hold the Indemnified Party harmless
from any and all costs, damages, claims, liabilities or expenses (including without limitation,
court costs and reasonable attorneys’ fees and disbursements) incurred by the Indemnified Party in
defending against the claim. In addition, Buyer shall indemnify Seller and the Seller Related
Parties and hold all such parties harmless from and against any and all costs, damages, claims,
liabilities or expenses (including without limitation, court costs and reasonable attorneys’ fees
and disbursements) arising out of or related to any failure by Buyer to pay, at Closing, the entire
Commission. The provisions of this Section 6.1 shall survive the Closing or, if the purchase and
sale is not consummated, any termination of this Agreement.

     Section 6.2 Expenses.

     Except as expressly provided in this Agreement, each party hereto shall pay its own expenses
incurred in connection with this Agreement and the transactions contemplated hereby.

ARTICLE VII

LEASES AND OTHER AGREEMENTS

     Section 7.1 Buyer’s Approval of New Leases and Agreements Affecting the Property.

     Between the Effective Date and the Closing, Seller shall continue to lease the Property in the
same manner as before the making of this Agreement, the same as though Seller were retaining the
Property, provided, however, that (y) prior to the expiration of the Contingency Period, Seller
shall provide written notice to Buyer of its intent to enter into a new lease or modify or
terminate any existing Lease and shall allow Buyer two (2) business days to provide comments to,
and/or recommendations with respect to, any such proposed action, provided, however, that Seller
shall have no obligation to incorporate or consider any such comments or recommendations, and the
determination of whether or not to enter into the Lease or Lease modification or termination shall
be in Seller’s sole discretion, and (z) after the expiration of the Contingency Period, Seller
shall not enter into any new Lease, or modify or terminate any

18

 

existing Lease which will be binding on the Property after Closing, except as permitted or
required under any Lease, without first obtaining Buyer’s approval of the proposed action, which
approval shall be granted or withheld in Buyer’s sole discretion. In order to be effective, any
such request by Seller for Buyer’s approval under part (z) of the immediately preceding sentence
shall be accompanied by (i) a copy of any proposed modification or amendment of an existing Lease
or a copy of any new Lease that Seller wishes to execute between the expiration of the Contingency
Period and the Closing Date, including, without limitation, to the extent not included in the Lease
or amendment to Lease, a description of any tenant improvement costs, leasing commissions, free
rent and any other concessions associated with any proposed renewal or expansion of an existing
Lease or with any such new Lease and (ii) appropriate financial information on the applicable
tenant and such other information as Buyer may reasonably require to the extent Seller has such
information in its possession. Further, after the expiration of the Contingency Period, Seller
shall not enter into any new agreement affecting the Property, or modify or terminate any agreement
affecting the Property, which will be binding on the Property after Closing, except for agreements
which are terminable on no more than thirty (30) days’ notice without payment of any penalty or fee
or other cost to the Property owner, without first obtaining Buyer’s approval of the proposed
action, which approval shall be granted or withheld in Buyer’s reasonable discretion. In case
Buyer disapproves any such request from Seller for approval under this Section 7.1, Buyer shall
specify in detail the reasons for its disapproval thereof. If Buyer fails to give Seller notice of
its approval or disapproval of any such proposed action requiring its approval under this Section
7.1 within three (3) business days after receipt of Seller’s notice requesting such approval,
(accompanied by the documents and materials described above), then Buyer shall be deemed to have
given its approval to the action or matter described in Seller’s request. Buyer agrees to
cooperate with Seller in enabling Seller to complete any such proposed transaction requiring
Buyer’s approval.

     Section 7.2 Tenant Improvement Costs, Leasing Commissions and Concessions.

     With respect to any new Lease or Lease modification entered into by Seller between the
Effective Date and the Closing Date, and with respect to any renewal or extension of any Lease,
whether through the exercise of an option or otherwise, occurring between such date and the Closing
Date, all tenant improvement work, leasing commissions, legal fees or other expenses or grants of
any free rent period or other concessions shall be paid by Buyer. Notwithstanding the foregoing,
Seller shall be responsible for all tenant improvement costs and leasing commissions payable by the
landlord pursuant to obligations arising from the current term of any existing Lease which is dated
on or before the Effective Date and executed and delivered by both the landlord and tenant
thereunder on or before such date. To the extent Seller has not paid any such amounts at Closing,
Buyer shall receive a credit therefor at Closing. Buyer shall reimburse Seller for all such costs,
expenses, free rent period or other concessions incurred by Seller to the extent Buyer is obligated
therefor pursuant to the provisions of this Section. Pursuant to the Assignment of Leases, Buyer
shall assume any then outstanding obligations with respect to such tenant improvements, leasing
commissions and concessions, provided that the foregoing does not limit Seller’s obligations under
this Section with respect to the current term of existing Leases executed and delivered by the
parties thereto on or before the Effective Date. The provisions of this Section shall survive the
Closing.

19

 

     Section 7.3 Tenant Notices.

     At the Closing, Seller shall furnish Buyer with a signed notice to be given to each tenant of
the Property. The notice shall disclose that the Property has been sold to Buyer, that, after the
Closing, all rents should be paid to Buyer and that Buyer shall be responsible for all the tenant’s
security deposit, the amount of which shall be set forth in such notice. The form of the notice
shall be otherwise reasonably acceptable to the parties. Buyer covenants to deliver said notices
to each tenant as soon as reasonably possible after Closing. This provision shall expressly
survive Closing.

     Section 7.4 Maintenance of Improvements and Operation of Property; Removal of Tangible
Personal Property.

     Seller agrees to keep its customary property insurance covering the Property in effect until
the Closing (provided, however, that the terms of any such coverage maintained in blanket form may
be modified as Seller deems necessary). Seller shall operate and manage the Property in a manner
consistent with Seller’s practices in effect prior to the Effective Date, provided that Seller
shall in no event be obligated to make any capital expenditures or repairs. Seller shall not
remove any Tangible Personal Property, except as may be required for necessary repair or
replacement, and replacement shall be of approximately equal in quality and quantity as the removed
item of Tangible Personal Property.

     Section 7.5 Service Contracts.

     Within three (3) business days prior to the expiration of the Contingency Period, Buyer will
advise Seller in writing which Service Contracts Buyer will assume and which Service Contracts
Buyer requests be terminated at Closing, provided Seller shall have no obligation to terminate, and
Buyer shall be obligated to assume, any Service Contracts which by their terms cannot be terminated
without penalty or payment of a fee or other cost to Seller. Seller shall deliver at Closing
notices of termination of all Service Contracts that are not so assumed and Buyer shall be
responsible for any charges applicable to periods commencing with the Closing. Notwithstanding the
foregoing, Seller shall terminate, as of the Closing Date, all existing management and leasing
agreements with respect to the Property.

     Section 7.6 Tax Appeal

     Seller hereby reserves the right to bring or continue a Tax Appeal or Tax Appeals after the
Closing Date with respect to its period of ownership of the Property, excluding, however, the
current tax year. Further, Seller shall have the right to control the proceedings of such Tax
Appeal, and shall have the right to collect any payments or credits which may result from such Tax
Appeal, provided that Seller shall return to tenants any sums Seller may owe to tenants under their
respective leases as a result of any sums received by Seller in connection with a Tax Appeal. Buyer
shall cooperate with Seller in the prosecution of such Tax Appeal without incurring any costs. If
Buyer brings a Tax Appeal or Tax Appeals with respect to its period of ownership, including the
current tax year, Buyer shall have the right to control the proceedings of such Tax Appeal and the
right to collect any payments or credit which may result therefrom, provided, however, that any
amounts due to Seller for Seller’s period of ownership shall be

20

 

promptly paid to Seller, and Seller shall cooperate with Buyer in the prosecution of such Tax
Appeal without incurring any costs. The provisions of this Section 7.6 shall survive the Closing.

     Section 7.7 Property Management Office Build-Out

     After the expiration of the Contingency Period, Buyer shall have a license to access and use a
vacant space in the Building more particularly described in Exhibit H attached hereto and
made a part hereof, consisting of approximately one thousand five hundred (1,500) square feet of
rentable space (the “Management Office Space”) for purposes of constructing a property management
office (the “Office Build-Out Work”). Buyer shall execute and deliver to Seller, prior to the end
of the Contingency Period, a license agreement to use such space, provided, however that such
license agreement shall be on Seller’s standard form of license agreement with changes thereto
reasonably requested by Buyer and reasonably approved by Seller during the Contingency Period. To
induce Seller to grant Buyer such access and use to the Management Office Space prior to Closing,
Buyer hereby agrees as follows:

          (a) Buyer shall not commence the Office Build-Out Work without first obtaining Seller’s prior
written approval, which approval shall be granted or withheld in Seller’s reasonable discretion, to
the plans and specifications for such work (the “Plans and Specifications”).

          (b) Buyer shall obtain and pay for all permits, licenses and approvals required by all
applicable laws with regard to the Office Build-Out Work.

          (c) Buyer shall perform and complete, or cause to be performed and completed, all work in
connection with the Office Build-Out Work (i) at Buyer’s sole cost and expense, (ii) in accordance
with the Plans and Specifications as reasonably approved by Seller, (iii) in a good and workmanlike
manner, (iv) in compliance with all applicable laws, ordinances, rules and regulations of federal,
state, county or municipal government or agencies now in force or that may be enacted hereafter,
and (v) without interfering with Seller’s or any of Seller’s tenants’ use and enjoyment of the
Property.

          (d) Buyer agrees to pay and discharge all claims for labor done and material and services
furnished in connection with the Office Build-Out Work. Buyer covenants and agrees that the Office
Build-Out Work shall be constructed or completed, as applicable, free and clear of any and all
liens (including, without limitation, mechanic’s, materialman’s or other liens), claims and
encumbrances whatsoever. If any claim is made or any liens should become perfected, Buyer shall
satisfy and remove such claim or the lien within ten (10) calendar days after receiving notice
thereof.

          (e) Until the earlier of the Closing or the completion of the Office Build-Out Work, Buyer
will (a) maintain comprehensive general liability (occurrence) insurance in an amount of not less
than Two Million Dollars ($2,000,000) covering any accident arising in connection with the presence
of Buyer, its agents, representatives, contractors, consultants or employees on the Property, and
deliver a certificate of insurance, which names the Seller and any other party requested by Seller
as additional insureds thereunder verifying such coverage to

21

 

Seller prior to commencement of the work, and (b) maintain such other insurance as Seller may
reasonably require.

          (f) Buyer shall hold harmless, indemnify and defend Seller from and against any and all
liabilities, obligations, claims, demands, damages, penalties, causes of action, losses, fines,
costs and expenses (including, without limitation, reasonable attorneys’ fees and expenses) imposed
upon or incurred by Seller arising from or in connection with, directly or indirectly, the Office
Build-Out Work. The provisions of this subsection shall survive Closing or any termination of this
Agreement.

          (g) If the sale of the Property is not consummated for any reason whatsoever, (a) Seller shall
have no obligation to reimburse Buyer for any expenses or costs incurred in connection with the
Office Build-Out Work, and (b) in the event that Buyer fails to complete the Office Build-Out Work,
Seller shall have the right to either complete the Office Build-Out Work or to return the
Management Office Space to the condition it was in prior to Buyer’s access to such space, and Buyer
shall promptly reimburse Seller for any costs or expenses incurred in connection therewith (the
“Reimbursement Costs”), provided, however, that in the event that this Agreement is terminated as a
result of a default by Buyer, and consequently Seller retains the Deposit, Buyer shall have no
obligation to reimburse Seller for the Reimbursement Costs.

     Section 7.8 Updates of Due Diligence Items

     From the date of this Agreement through the Closing, Seller will promptly provide Buyer with
updates with respect to any material changes to any of the material Due Diligence Items of which
Seller becomes aware.

     Section 7.9 Reservation of Rights.

     Notwithstanding anything to the contrary contained herein or in any of the Closing Documents,
and except with respect to the Art Work Escrow (as such term is defined in the Assignment of
Leases), Seller reserves all rights of the purchasers against the sellers under those certain
purchase and sale agreements (and all amendments and modifications thereto) governing the sale of
the Property to Seller. Seller reserves the right from time to time prior to Closing to draw down
sums from the Art Work Escrow for the purposes set forth therein. The provisions of this Section
7.9 shall survive the Closing.

ARTICLE VIII

CLOSING AND ESCROW

     Section 8.1 Escrow Instructions.

     Upon execution of this Agreement, the parties hereto shall deposit an executed counterpart of
this Agreement with the Title Company, and this instrument shall serve as the instructions to the
Title Company as the escrow holder for consummation of the purchase and sale contemplated hereby.
Seller and Buyer agree to execute such reasonable additional and supplementary escrow instructions
as may be appropriate to enable the Title Company to comply with the terms of this Agreement;
provided, however, that in the event of any conflict between

22

 

the provisions of this Agreement and any supplementary escrow instructions, the terms of this
Agreement shall control.

     Section 8.2 Closing.

     The Closing hereunder shall be held and delivery of all items to be made at the Closing under
the terms of this Agreement shall be made at the offices of the Title Company or as otherwise
mutually agreed on October 2, 2006, and before 8:30 a.m. local time, or such other earlier date and
time as Buyer and Seller may mutually agree upon in writing (the “Closing Date”). Except as
expressly provided herein, such date and time may not be extended without the prior written
approval of both Seller and Buyer.

     Section 8.3 Deposit of Documents.

          (a) At or before the Closing, Seller shall deposit into escrow the following items:

               (1) the duly executed and acknowledged Deed in the form attached hereto as Exhibit C
conveying the Real Property to Buyer subject to the Conditions of Title;

               (2) four (4) duly executed counterparts of the Bill of Sale in the form attached hereto as
Exhibit D (the “Bill of Sale”);

               (3) four (4) duly executed counterparts of an Assignment and Assumption of Leases, Service
Contracts, Warranties and Other Intangible Property in the form attached hereto as Exhibit
E pursuant to the terms of which Buyer shall assume all of Seller’s obligations under the
Leases, Service Contracts, and other documents and agreements affecting the Property (the
“Assignment of Leases”);

               (4) an affidavit pursuant to Section 1445(b)(2) of the Code, and on which Buyer is entitled to
rely, that Seller is not a “foreign person” within the meaning of Section 1445(f)(3) of the Code;

               (5) California 593-C Certificate; and

               (6) Such other documents or items which Seller is expressly required to deliver at Closing
pursuant to this Agreement (including, without limitation, tenant letters of credit in Seller’s
possession at Closing, which with respect to such letters of credit, Seller agrees, upon Buyer’s
request and at Buyer’s sole cost and expense, to cooperate with Buyer in obtaining letters of
credit reissued to name Buyer as beneficiary after Closing).

          (b) At or before Closing, Buyer shall deposit into escrow the following items:

               (1) immediately available funds necessary to close this transaction, including, without
limitation, the Purchase Price (less the Deposit and interest thereon net of investment fees, if
any) and funds sufficient to pay Buyer’s closing costs and share of prorations hereunder, net of
any credits to Buyer required by this Agreement;

23

 

               (2) four (4) duly executed counterparts of the Bill of Sale; and

               (3) four (4) duly executed counterparts of the Assignment of Leases.

          (c) Seller and Buyer shall each execute and deposit a closing statement, such transfer tax
declarations and such other instruments (including, without limitation, appropriate evidence of the
authority of such party) as are reasonably required by the Title Company or otherwise required to
close the escrow and consummate the acquisition of the Property in accordance with the terms
hereof. Seller and Buyer hereby designate Title Company as the “Reporting Person” for the
transaction pursuant to Section 6045(e) of the Code and the regulations promulgated thereunder and
agree to execute such documentation as is reasonably necessary to effectuate such designation.

          (d) Within five (5) business days after the Closing Date, Seller shall deliver or make
available at the Property to Buyer: originals of the Leases to the extent in Seller’s possession,
or copies of any Leases not in Seller’s possession, copies of the tenant correspondence files in
Seller’s possession, and originals of any other items which Seller was required to furnish Buyer
copies of or make available at the Property pursuant to Sections 2.1(b) or (e) above, to the extent
in Seller’s possession, except for Seller’s general ledger and other internal books or records
which shall be retained by Seller. Seller shall deliver possession of the Property to Buyer as
required hereunder and shall deliver to Buyer or make available at the Property all keys, pass
codes and access devices held by Seller or its property manager with respect to the Property on the
Closing Date.

     Section 8.4 Estoppel Certificates.

          (a) If in accordance with Article II of this Agreement Buyer elects to proceed with the
purchase of the Property, then Seller shall use commercially reasonable efforts to obtain estoppel
certificates from each tenant of the Property substantially in the form attached hereto as
Exhibit F (except with respect to the estoppel certificate to be obtained from Health Net,
Inc., as described below) or, if a tenant’s Lease requires a different form, in the form required
by the tenant’s Lease, or as otherwise provided in this paragraph below. On or before September
15, 2006, Seller shall submit to each tenant of the Property an estoppel certificate in the form of
said Exhibit F (except as otherwise provided below) and request that such tenant sign and
return such certificate to Seller within ten (10) days. It shall be a condition to Buyer’s
obligation to Close the sale and purchase of the Property that on or before the Closing, Buyer is
able to obtain an estoppel certificate (x) substantially in such form attached hereto as
Exhibit F-1 from Health Net, Inc., (“Health Net”) and (y) substantially in such form
attached hereto as Exhibit F from (i) four of the following five tenants: Netzero, Inc.,
ATK Missile Systems Company, LLC, Poms & Associates Insurance Brokers, Inc., Care Level Management,
and Univision Music, LLC (each such Tenant and Health Net, a “Major Tenant” and collectively, the
“Major Tenants”) and (ii) from such other tenants of the Property, which, together with the Major
Tenants lease and occupy at least seventy-five percent (75%) of the area of the Property actually
rented to tenants (collectively, the “Estoppel Threshold”). All estoppel certificates shall be
dated no more than thirty (30) days prior to the Closing Date. An estoppel certificate, even
though not in the form of Exhibit F, will be deemed to be acceptable to Buyer (i) if it is
substantially on the standard form attached to the applicable tenant’s Lease (so long as Buyer is
not otherwise entitled to object

24

 

thereto pursuant to Section 8.4(b) below) and (ii) even if any tenant modifies or deletes
Paragraph 13 from the Exhibit F form returned by such tenant. If Seller is unable to
satisfy the Estoppel Threshold, Seller may (but is not required to) deliver estoppel certificates
in the form of Exhibit F-2 executed by Seller covering such leases as are sufficient, when
aggregated with the tenant estoppel certificates previously delivered, to satisfy the Estoppel
Threshold, provided that Buyer shall not be obligated to accept Seller estoppel certificates that
collectively cover in excess of twenty percent (20%) of the area of the Property actually rented to
tenants or which are in lieu of an estoppel certificate for any of the Major Tenants. Seller’s
representations and warranties in any Seller estoppel certificates will survive the Closing,
subject to the limitations contained in Sections 3.2, 3.3, 3.4, 9.11 and 9.19 hereof. In the event
that Buyer receives an estoppel certificate from a tenant complying with the requirements of this
Section 8.4 and for which Seller previously delivered a Seller estoppel certificate in accordance
herewith, Seller shall be automatically released from any liability or obligation under such Seller
estoppel certificate, except with respect to those provisions, if any, which materially conflict
with the provision(s) covering the same in the applicable Seller estoppel(s), provided, however,
that all such provisions shall still be subject to the limitations contained in Sections 3.2, 3.3,
3.4, 9.11 and 9.19 hereof.

          (b) If Seller is unable to obtain and deliver sufficient tenant estoppel certificates in
accordance with Section 8.4(a), or if the certificates received or substituted Seller estoppels
contain material information or omissions unacceptable to Buyer in its reasonable discretion and
Buyer objects thereto by written notice to Seller within two (2) business days after receipt by
Buyer of the objectionable estoppel, but in any event on or before the Closing Date, then Seller
will not be in default by reason thereof, and Seller may elect to extend the Closing Date by up to
thirty (30) days in order to satisfy the requirement. If Seller still cannot satisfy the
requirement at the end of such extended period, then Buyer may, by written notice given to Seller
before the Closing, elect to terminate this Agreement and receive a refund of the Deposit or waive
said condition. If Buyer so elects to terminate this Agreement, neither party shall have any
further rights or obligations hereunder except as provided in Section 6.1 above and Sections 9.3
and 9.9 below. If no such termination notice is delivered by Buyer, Buyer shall be deemed to have
waived such condition.

     Section 8.5 Prorations.

          (a) Rents, including, without limitation, percentage rents, if any, and any additional charges
and expenses payable by tenants under Leases, all as and when actually collected (except for tenant
CAM Charges (as such term is defined below), which will be prorated at Closing based on estimates
of the same, all in accordance with the provisions of Section 8.5(b) below); real property taxes
and assessments; water, sewer and utility charges; amounts payable under any Service Contracts or
other agreements or documents; annual permits and/or inspection fees (calculated on the basis of
the period covered); and any other expenses of the operation and maintenance of the Property, but
specifically excluding the cost of insurance, (including, without limitation, expenses prepaid by
Seller and expenses already paid by Seller but which are being amortized over time by Seller and
with respect to which Seller shall receive a credit at Closing in the amount of the prepaid or
unamortized portion thereof), shall all be prorated as of 11:59 p.m. on the day immediately prior
to Closing (i.e., Buyer is entitled to the income and responsible for the expenses of the day of
Closing), on the basis of a 365-day year.

25

 

The preliminary estimated Closing prorations contemplated by this Section 8.5(a) shall be
prepared by Seller and submitted to Buyer for review and approval on or before September 26, 2006.
Buyer and its representatives shall be afforded reasonable access to Seller’s books and records
with respect to back-up evidence and Seller’s work papers pertaining to such preliminary prorations
to confirm the accuracy thereof. Such prorations, once agreed upon by Buyer and Seller, shall be
delivered to the Title Company for purposes of making the preliminary proration adjustments at
Closing, subject to the final cash settlement provided for below. The preliminary proration shall
be paid at Closing by Buyer to Seller (if the preliminary prorations result in a net credit to
Seller) or by Seller to Buyer (if the preliminary prorations result in a net credit to Buyer) by
increasing or reducing the cash to be delivered by Buyer in payment of the Purchase Price at the
Closing.

     Additionally, Buyer shall reimburse Seller for the tenant improvement costs, leasing
commissions, legal fees and other expenses, and free rent and other concessions, as provided in
Section 7.2. Buyer shall be entitled the credits due Buyer from Seller, if any, as expressly set
forth in Section 7.2.

     All rents collected after the Closing shall be applied and paid as provided in this Section
8.5(a). If a tenant shall specifically designate a payment as being attributable to, or if it is
readily ascertainable that a payment received from a tenant is attributable to a specific period of
time or for a specific purpose, including, without limitation, for operating expenses or real
estate tax payments which were not paid or were underpaid by such tenant or for reimbursement for
work performed by Seller on the tenant’s premises, such payment shall be so applied. If there is
no such designation or if not so readily ascertainable, any payment received from a tenant after
Closing shall be deemed a payment of rent due after the Closing until the tenant is current on
rents and sums due under the applicable Lease on or after the Closing, and then such payments shall
be paid to Seller to the extent of any rent or other sums owing to Seller for periods prior to
Closing. Buyer shall use reasonable efforts to collect such rents and other sums owing to Seller.

          (b) On or before the Closing, Seller will prepare an estimate, as of the Closing, of the
amounts of all taxes, insurance charges and other expenses owed by tenants under the Leases
(collectively “CAM Charges”), as specified in the Leases (collectively, “Operating Expense
Recoveries”) for the portion of calendar year 2006 during which Seller owned the Property (the
“2006 Partial Year”). If the amounts collected by Seller from tenants for Operating Expense
Recoveries for the 2006 Partial Year are less than the amounts that would have been owed by tenants
under the tenant Leases for such items based on Seller’s estimate, Buyer will pay such difference
to Seller at Closing. If the amounts collected by Seller from tenants for Operating Expense
Recoveries for the 2006 Partial Year are greater than the amounts that would have been owed by
tenants under the tenant Leases for such items based on Seller’s estimate, Seller will pay to Buyer
at Closing such difference.

     A final reconciliation of the CAM Charges and Operating Expense Recoveries for the 2006
Partial Year shall be prepared by Seller, and delivered to Buyer, on or before December 31, 2006,
in accordance with the requirements set forth in the Leases and as provided in this Section 8.5(b).
Thereafter, Buyer shall have ten (10) business days to reasonably approve of or object to, in
writing, such reconciliation. In the event that Buyer does not object in writing to Seller within
such time period, the reconciliation shall be deemed final and approved by Buyer. When the

26

 

reconciliation is reasonably approved by Buyer or is deemed approved by Buyer pursuant to this
Section, the party owing the other party a sum of money based on such reconciliation shall pay said
sum of money to the other party.

     With respect to any audit of any CAM Charges applicable to any period of time from and after
the Closing billed to Health Net, Buyer agrees to indemnify, hold harmless and defend Seller from
and against any and all amounts owing as a result of said Health Net Cam Charges audit. With
respect to any audit of any CAM Charges applicable to calendar-year 2005 which were billed to
Health Net (a “2005 Health Net CAM Audit”), Seller agrees to indemnify, hold harmless and defend
Buyer from and against any and all amounts owed to Health Net as a result of said 2005 Health Net
CAM Audit (collectively, “Audit Claims”), provided, however, that the indemnity described in this
sentence shall survive only for the period of time that Health Net has the right to conduct a 2005
Health Net CAM Audit pursuant to the express provisions of the Health Net Lease of the Property,
provided, however, that if a 2005 Health Net CAM Audit has been commenced within such allotted time
period, such indemnity shall survive until such 2005 Health Net CAM Audit has been resolved (the
“Audit Survival Period”). Any such Audit Claim which Buyer may have at any time against Seller,
whether known or unknown, which is not specifically asserted by written notice to Seller within
such time period shall not be valid or effective, and neither Seller nor any Seller Related Parties
shall have any liability with respect thereto. In connection with any 2005 Health Net CAM Audit,
Seller and Buyer shall each have the right to participate in any such audit, and each such party
shall cooperate with the other in connection therewith.

     The amount of any cash security deposits held by Seller under Leases shall be credited against
the Purchase Price (and Seller shall be entitled to retain such cash security deposits). Seller
shall receive credits at Closing for the amount of any utility or other similar deposits with
respect to the Property and to the extent practical, shall pay to the applicable utility providers
all utility charges payable with respect to the Property for the period prior to Closing. Buyer
shall cause all utilities to be transferred into Buyer’s name and account at the time of Closing.

     Seller and Buyer hereby agree that if any of the aforesaid prorations and credits cannot be
calculated accurately on the Closing Date or in the case of rents or other charges received from
tenants, which have not been collected as of the Closing Date, then the same shall be calculated as
soon as reasonably practicable (except that the CAM Charges and Operating Expense Recoveries shall
be calculated within the timeframes described above) but in any event within sixty (60) days after
the Closing Date or the date that such amounts have been collected by either party, and either
party owing the other party a sum of money based on such subsequent proration(s) or credits shall
pay said sum to the other party within thirty (30) days thereafter. Notwithstanding the foregoing,
in the event that either party collects rent or other charges from tenants that were not collected
at Closing, such party owing the other party a sum of money with respect to such rent or other
charges from tenants, shall use commercially reasonable efforts to pay said sum to the other party
within five (5) business days after receipt of such sum. Any amounts not paid within ten (10) days
after receipt of such sum shall bear interest from the date actually received by the payor until
paid at the greater of (i) the rate of ten percent (10%) per annum or (ii) the prime rate (or base
rate) reported from time to time in the “Money Rates” column or section of The Wall Street
Journal as being the base rate on corporate loans at larger United States money center
commercial banks plus two (2) percent. Upon request of either

27

 

party, the parties shall provide a detailed and accurate written statement signed by such
party certifying as to the payments received by such party from tenants from and after Closing and
to the manner in which such payments were applied, and shall make their books and records available
for inspection by the other party during ordinary business hours upon reasonable advance notice.

          (c) If the Closing occurs, Seller shall pay (i) the title insurance premium for the CLTA
portion of the Title Policy, (ii) any costs incurred in recording the Deed or any other instruments
with respect to the transfer contemplated herein, and (iii) all costs to satisfy, release and
discharge any Seller’s Liens. If the Closing occurs, Buyer shall pay (i) the costs of extended
coverage and any endorsements to the Owner’s Policy, (ii) the costs, if any, to obtain the updated
Survey or a new survey, (iii) all state, county and city transfer taxes, if any, payable in
connection with the consummation of the sale of the Property to Buyer as contemplated herein, and
(iv) all fees, costs, or expenses in connection with Buyer’s due diligence reviews hereunder. Any
other closing costs shall be allocated in accordance with local custom as determined by the Title
Company. Any escrow fees shall be split equally between Seller and Buyer. The parties will
execute and deliver any required transfer or other similar tax declarations to the appropriate
governmental entity at Closing.

          (d) Any percentage rent for the rental periods including Closing shall be prorated upon
receipt, based upon the tenant’s sales for the portion of the lease year allocable to Seller’s and
Buyer’s respective ownership of the Property.

          (e) The provisions of this Section 8.5 shall survive the Closing.

party. Any notice or other communication sent as hereinabove provided shall be deemed effectively
given (a) on the date of delivery, if delivered in person; (b) on the date mailed if sent by
certified mail, postage prepaid, return receipt requested or by a commercial overnight courier; or
(c) on the date of transmission, if sent by facsimile with confirmation of receipt. Such notices

transmission (provided such transmission occurs on a business day and during the recipient’s normal
business hours), if sent by facsimile. If any notice mailed is properly addressed but returned for
any reason, such notice shall be deemed to be effective notice and to be given on the date of
mailing. Any notice sent by the attorney representing a party, shall qualify as notice under this
Agreement.

     Section 9.2 Entire Agreement.

     This Agreement, together with the Exhibits and Schedules attached hereto, contains all
representations, warranties and covenants made by Buyer and Seller and constitutes the entire
understanding between the parties hereto with respect to the subject matter hereof. Any prior
correspondence, memoranda or agreements are replaced in total by this Agreement together with the
Exhibits and Schedules hereto.

     Section 9.3 Entry and Indemnity.

     In connection with any entry by Buyer, or its agents, employees or contractors onto the
Property, Buyer shall give Seller reasonable advance notice of such entry and shall conduct such
entry and any inspections in connection therewith (a) during normal business hours, (b) so as to
minimize, to the greatest extent possible, interference with Seller’s business and the business of
Seller’s tenants, (c) in compliance with all applicable laws, and (d) otherwise in a manner
reasonably acceptable to Seller. Without limiting the foregoing, prior to any entry to perform any
on-site testing, including but not limited to any air sampling, borings, drillings or other
samplings, Buyer shall give Seller written notice thereof, including the identity of the company or
persons who will perform such testing and the proposed scope and methodology of the testing.
Seller shall approve or disapprove, in Seller’s sole discretion, the proposed testing within three
(3) business days after receipt of such notice (provided that Seller’s approval shall not be
required for a non-invasive Phase I Environmental Site Assessment but excluding air quality testing
and evaluation, other than such air quality testing and evaluation for carbon monoxide and carbon
dioxide for which Seller’s approval shall not be required). If Seller fails to respond within such
three (3) business day period, Seller shall be deemed to have disapproved the proposed testing. If
Buyer or its agents, employees or contractors take any sample from the Property in connection with
any such approved testing, Buyer shall provide to Seller a portion of such sample being tested to
allow Seller, if it so chooses, to perform its own testing. Buyer shall permit Seller or its
representative to be present to observe any testing or other inspection or due diligence review
performed on or at the Property. Upon the request of Seller, Buyer shall promptly deliver to
Seller copies of any reports relating to any testing or other inspection of the Property performed
by Buyer or its agents, representatives, employees, contractors or consultants. Notwithstanding
anything to the contrary contained herein, Buyer shall not contact any governmental authority
without first obtaining the prior written consent of Seller thereto in

30

 

Seller’s sole discretion, and Seller, at Seller’s election, shall be entitled to have a
representative participate in any telephone or other contact made by Buyer to a governmental
authority and present at any meeting by Buyer with a governmental authority; provided, however,
that Buyer or its agents, employees or contractors may make informational inquiries of governmental
officials and representatives with regards to a Phase I environmental review and preparation,
zoning issues and any other matters which do not relate to any environmental issues (except with
respect to the Phase I review and preparation as set forth above). Further, Buyer shall not
contact any tenant without first obtaining the prior written consent of Seller thereto in Seller’s
reasonable discretion, provided, however, that Seller, at Seller’s election, shall be entitled to
have a representative participate in any telephone or other contact made by Buyer to a tenant and
present at any meeting by Buyer with a tenant. In the event Seller fails to consent to or approve
(or is deemed to have denied or disapproved) any request by Buyer hereunder for any testing or
studies, or any interviews, contact or meetings with tenants, governmental authorities or other
third parties, or other matters requiring Seller’s approval hereunder, Buyer may terminate this
Agreement prior to the Contingency Period, whereupon the Deposit shall be returned to Buyer. If
Buyer does not timely elect to terminate this Agreement prior to the end of the Contingency Period,
Buyer shall be deemed to have waived its right to terminate this Agreement under this Section.
Buyer shall maintain, and shall assure that its contractors maintain, public liability and property
damage insurance in amounts (but in no event less than Two Million Dollars ($2,000,000) with
respect to any liability insurance) and in form and substance adequate to insure against all
liability of Buyer and its agents, employees or contractors, arising out of any entry or
inspections of the Property pursuant to the provisions hereof, and Buyer shall provide Seller with
evidence of such insurance coverage prior to any entry on the Property. Buyer shall indemnify and
hold Seller harmless from and against any costs, damages, liabilities, losses, expenses, liens or
claims (including, without limitation, court costs and reasonable attorneys’ fees and
disbursements) arising out of or relating to any entry on the Property by Buyer, its agents,
employees or contractors in the course of performing the inspections, testings or inquiries
provided for in this Agreement, including, without limitation, any release of Hazardous Materials
or any damage to the Property; provided that Buyer shall not be liable to Seller solely as a result
of the discovery by Buyer of a pre-existing condition on the Property to the extent the activities
of Buyer, its agents, representatives, employees, contractors or consultants do not exacerbate the
condition. The provisions of this Section 9.3 are in substitution and replacement of the
provisions of the Access Agreement (as defined in Section 9.9 below) and the provisions (including
the above indemnity and hold harmless provisions) shall be deemed to extend and apply to any entry
upon the Property by Buyer, its agents, representatives, employees, contractors or consultants
under the Access Agreement. The foregoing indemnity shall survive beyond the Closing, or, if the
sale is not consummated, beyond the termination of this Agreement. Buyer’s right of entry, as
provided in this Section 9.3, shall continue up through the date of Closing.

     Section 9.4 Time.

     Time is of the essence in the performance of each of the parties’ respective obligations
contained herein.

31

 

     Section 9.5 Attorneys’ Fees.

     If either party hereto fails to perform any of its obligations under this Agreement or if any
dispute arises between the parties hereto concerning the meaning or interpretation of any provision
of this Agreement, whether prior to or after Closing, or if any party defaults in payment of its
post-Closing financial obligations under this Agreement, then the defaulting party or the party not
prevailing in such dispute, as the case may be, shall pay any and all costs and expenses incurred
by the other party on account of such default and/or in enforcing or establishing its rights
hereunder, including, without limitation, court costs and reasonable attorneys’ fees and
disbursements.

     Section 9.6 Assignment.

     Buyer’s rights and obligations hereunder shall not be assignable without the prior written
consent of Seller in Seller’s sole discretion. Notwithstanding the foregoing, Buyer shall have the
right, without the necessity of obtaining Seller’s consent but with prior written notice to Seller,
to assign its right, title and interest in and to this Agreement to either a wholly owned
subsidiary of Buyer or to an entity which is owned, in majority, by Buyer and in minority by
investors and entities advised by General Motors Investment Management Corporation, at any time
before the Closing Date. Buyer shall in no event be released from any of its obligations or
liabilities hereunder in connection with any assignment. Without limiting and notwithstanding the
above, in no event shall Buyer have the right to assign its rights or obligations hereunder to any
party which could not make the representation and warranty contained in subsection 3.5(e) above,
and in connection with any assignment pursuant to the terms hereof, the assignee shall reconfirm in
a written instrument acceptable to Seller and delivered to Seller prior to the effective date of
the assignment said representation and warranty as applied to the assignee and that all other terms
and conditions of this Agreement shall apply to such assignee. Subject to the provisions of this
Section, this Agreement shall inure to the benefit of and be binding upon the parties hereto and
their respective successors and assigns.

     Section 9.7 Counterparts.

     This Agreement may be executed in two or more counterparts, each of which shall be deemed an
original, but all of which taken together shall constitute one and the same instrument.

     Section 9.8 Governing Law.

     This Agreement shall be governed by and construed in accordance with the laws of the State of
California.

     Section 9.9 Confidentiality and Return of Documents.

     Buyer and Seller shall each maintain as confidential any and all material obtained about the
other or, in the case of Buyer, about the Property, this Agreement or the transactions contemplated
hereby, and shall not disclose such information to any third party. Except as may be required by
law, Buyer will not divulge any such information to other persons or entities including, without
limitation, appraisers, real estate brokers, or competitors of Seller. Notwithstanding the
foregoing, Buyer shall have the right to disclose information with respect to

32

 

the Property (i) to its officers, directors, employees, attorneys, accountants, environmental
auditors, engineers, potential lenders, investors, and permitted assignees under this Agreement and
other consultants to the extent necessary for Buyer to evaluate its acquisition of the Property
provided that all such persons are told that such information is confidential and agree (in writing
for any third party engineers, environmental auditors or other consultants) to keep such
information confidential, and (ii) as may be reasonably necessary for Buyer, its affiliates or any
entity advised by Buyer’s affiliates to comply with any applicable federal or state securities
laws, rules, or regulations or to comply with the requirements of the SEC, the New York Stock
Exchange or any similar agency or body. If Buyer acquires the Property from Seller, Seller shall
have the right, subsequent to the Closing of such acquisition, to publicize the transaction (other
than the parties to or the specific economics of the transaction) in whatever manner it deems
appropriate; provided that any press release or other public disclosure regarding this Agreement or
the transactions contemplated herein, and the wording of same, must be reasonably approved in
advance by both parties. The provisions of this paragraph shall survive the Closing or any
termination of this Agreement for a period of two (2) years. In the event the transaction
contemplated by this Agreement does not close as provided herein, upon the request of Seller, Buyer
shall promptly return to Seller all Due Diligence Materials provided by Seller or any of the Seller
Related Parties and copies of any other documents and materials obtained by Buyer in connection
with the purchase of the Property hereunder (excluding, however, documents, materials and other
information of a proprietary nature prepared by Buyer in connection with this transaction).
Notwithstanding anything to the contrary contained herein, the provisions of this Section 9.9 shall
not apply to documents, materials, memoranda, notes, analyses, reports, compilations, studies, data
or other written or oral information which (a) is or becomes available to the general public other
than as a result of a disclosure by Buyer or its representatives or any of their consultants,
agents, employees or anyone else acting through any of them, or (b) was in Buyer’s or its
representatives possession on what Buyer reasonably believed to be a non-confidential basis prior
to its disclosure by Seller.

     Prior to the Effective Date, Buyer and Seller entered into a Confidentiality and Access
Agreement (the “Access Agreement”) governing Buyer’s early entry upon the Property and Buyer’s
obligations with respect to confidential information. Buyer and Seller hereby agree that the
Access Agreement is superseded and replaced by this Agreement; it being understood that the
provisions of this Section 9.9 and the provisions of Section 9.3 above apply to all information
provided to Buyer pursuant to, and to any and all entries, inspections, tests and other activities
of Buyer under, the Access Agreement whether prior to or after the date of this Agreement.

     Section 9.10 Interpretation of Agreement.

     The article, section and other headings of this Agreement are for convenience of reference
only and shall not be construed to affect the meaning of any provision contained herein. Where the
context so requires, the use of the singular shall include the plural and vice versa and the use of
the masculine shall include the feminine and the neuter. The term “person” shall include any
individual, partnership, joint venture, corporation, trust, unincorporated association, any other
entity and any government or any department or agency thereof, whether acting in an individual,
fiduciary or other capacity.

33

 

     Section 9.11 Limited Liability.

     The obligations of Seller under this Agreement and under all of the Other Documents are
intended to be binding only on the property of Seller and shall not be personally binding upon, nor
shall any resort be had to, the private properties of any Seller Related Parties, subject, however,
to the provisions of Sections 9.20 and 9.21 below.

     Section 9.12 Amendments.

     This Agreement may be amended or modified only by a written instrument signed by Buyer and
Seller.

     Section 9.13 No Recording.

     Neither this Agreement or any memorandum or short form thereof may be recorded by Buyer.

     Section 9.14 Drafts Not an Offer to Enter Into a Legally Binding Contract.

     The parties hereto agree that the submission of a draft of this Agreement by one party to
another is not intended by either party to be an offer to enter into a legally binding contract
with respect to the purchase and sale of the Property. The parties shall be legally bound with
respect to the purchase and sale of the Property pursuant to the terms of this Agreement only if
and when the parties have been able to negotiate all of the terms and provisions of this Agreement
in a manner acceptable to each of the parties in their respective sole discretion, and both Seller
and Buyer have fully executed and delivered to each other a counterpart of this Agreement (or a
copy by facsimile transmission).

     Section 9.15 ERISA.

     Without limiting Buyer’s representation and warranty in Section 3.5(e) above, within ten (10)
days after the Effective Date, Buyer shall furnish to Seller all information regarding Buyer, its
affiliates and the shareholders, members, investors or partners of each of them and any permitted
assignees of Buyer hereunder (collectively, the “Buyer Related Parties” and individually each a
“Buyer Related Party”) as Seller requests in order to enable Seller to determine to Seller’s sole
satisfaction that Buyer’s representation and warranty contained in Section 3.5(e) of this Agreement
is true and correct. Buyer represents and warrants and covenants to Seller that there will not be
any change in any such information regarding Buyer or the Buyer Related Parties prior to or on the
Closing. In the event any such information or change in Seller’s reasonable judgment makes this
transaction a sale to a party-in-interest, Seller may terminate this Agreement without liability on
the part of Seller or Buyer (provided such change did not occur as a result of a default by Buyer),
other than Buyer’s indemnity contained in Section 9.3 hereof and the obligations of Buyer contained
in Sections 6.1 and 9.9 hereof, and the Deposit will be returned to Buyer.

34

 

     Section 9.16 No Partnership.

     The relationship of the parties hereto is solely that of seller and buyer with respect to the
Property and no joint venture or other partnership exists between the parties hereto. Neither
party has any fiduciary relationship hereunder to the other.

     Section 9.17 No Third Party Beneficiary.

     The provisions of this Agreement are not intended to benefit any third parties.

     Section 9.18 SEC Compliance.

     Seller acknowledges that audited financial statements pertaining to the Property for three (3)
prior calendar years of operation and the portion of the calendar year in which Closing occurs up
to the Closing Date are required to be filed by the Buyer with the Securities and Exchange
Commission (the “SEC”) after the Closing. Accordingly, Seller agrees to provide Buyer and its
representatives with reasonable access to Seller’s books and records after the close of escrow upon
reasonable advance notice in order only to conduct the required audit. Seller shall cooperate (at
no cost to Seller) with Buyer and its auditor in the conduct of such audit by making its files
available and allowing Buyer and its auditors the right to interview Seller’s staff upon request by
Buyer; provided, however, that (i) neither Seller nor its staff shall have any obligation to sign
or execute any letter or any other document in connection therewith, and (ii) none of Buyer, the
SEC or Buyer’s auditors shall have the right to rely on any interview with Seller’s staff and none
of Seller, any of the Seller Related Parties or any of Seller’s staff shall have any liability in
connection therewith.

     Section 9.19 Limitation on Liability.

     Notwithstanding anything to the contrary contained herein, after the Closing: (a) the maximum
aggregate liability of Seller, and the maximum aggregate amount which may be awarded to and
collected by Buyer (including, without limitation, for any breach of any representation, warranty
and/or covenant by Seller) in connection with the Property and/or the sale thereof to Buyer
including, without limitation, under this Agreement or any documents executed pursuant hereto or in
connection herewith, including, without limitation, the Deed, the Bill of Sale, the Assignment of
Leases and any Seller estoppel certificate (collectively, the “Other Documents”, shall under no
circumstances whatsoever exceed an amount equal to Three Million One Hundred Fifty Thousand Dollars
($3,150,000)); and (b) no claim by Buyer alleging a breach by Seller of any representation,
warranty and/or covenant of Seller contained herein or in any of the Other Documents may be made,
and Seller shall not be liable for any judgment in any action based upon any such claim, unless and
until such claim, either alone or together with any other claims by Buyer alleging a breach by
Seller of any such representation, warranty and/or covenant is for an aggregate amount in excess of
Twenty-Five Thousand Dollars ($25,000) (the “Floor Amount”), in which event Seller’s liability
respecting any final judgment concerning such claim or claims shall be for the entire amount
thereof, subject to the limitation set forth in clause (a) above; provided, however, that if any
such final judgment is for an amount that is less than or equal to the Floor Amount, then Seller
shall have no liability with respect thereto.

35

 

     Section 9.20 Net Worth Covenant.

     Seller shall maintain a net worth equal to Three Million One Hundred Fifty Thousand Dollars
($3,150,000) for a period of nine (9) months from and after the Closing Date, provided, however,
that such amount shall be reduced by any amount paid to Buyer or any third party in connection with
any claim against Seller made pursuant to the provisions of this Agreement after the Closing Date.
In the event that Seller is liable to Buyer for a claim pursuant to the express terms and
conditions of this Agreement (each, a “Claim”), and in the event that Seller does not comply with
the terms of the preceding sentence, Buyer shall have the right to make a Claim against the
proceeds received by Seller from Buyer in connection with the Closing of the transaction
contemplated herein, (i) but only in the amount of Seller’s actual liability to Buyer with respect
to such Claim, and (ii) any such Claim shall be subject to the limitations on liability provided
for in Section 9.19 above, this Section 9.20, and the other provisions hereof. Notwithstanding
Section 9.23 below, this Section 9.20 shall survive the Closing for only a period of nine (9)
months (the “Survival Period”).

     Section 9.21 Survival of Audit Claims.

     In the event that after the expiration of Survival Period, but prior to the expiration of the
Audit Survival Period, an Audit Claim is brought, and Seller is liable therefor pursuant to the
terms of Section 8.5(b) above, then Buyer may make a Claim against Seller with respect to said
liability; provided however, if Seller has not adequately reserved for said liabilities, Buyer
shall have the right to make a Claim with respect to said liability against the proceeds received
by Seller from Buyer in connection with the Closing of the transaction contemplated herein, in each
case, (y) only in the amount of Seller’s actual liability to Buyer with respect to such Claim, and
(z) any such Claim shall be subject to the limitations on liability provided for in Section 9.19
above and this Section 9.21. Notwithstanding Section 9.23 below, this Section 9.21 shall survive
the Closing only until the expiration of the Audit Survival Period.

     Section 9.22 Environmental Notice.

     Pursuant to California Health & Safety Code Section 25359.7, which requires sellers of
commercial real estate to disclose the known existence of hazardous substances that have come to be
located on or beneath any real property being sold or transferred, Seller hereby discloses that
parcels of the Property contain, or may contain, Hazardous Materials, as more particularly
described in the those environmental reports and environmental disclosures described on
Schedule 1. Buyer acknowledges and agrees that in providing such environmental reports and
disclosures, Seller has satisfied its obligations of disclosure, to the extent required by
California Health & Safety Code Section 25359.7, and that except as expressly set forth in Section
3.1 above, no representation is being made or given by Seller regarding the presence or absence of
any environmental matters or conditions on or affecting all or any portion of the Property.

     Section 9.23 Survival.

     Except as expressly set forth to the contrary herein, no representations, warranties,
covenants or agreements of Seller contained herein shall survive the Closing.

36

 

     Section 9.24 Survival of Article IX.

     The provisions of this Article IX shall survive the Closing.

* * * * *

Million Nine Hundred Fifty Three Thousand Eight Hundred Eighty Nine Dollars
($275,953,889) (plus or minus the prorations pursuant to Section 8.5 hereof and plus
or minus the other credits specifically set forth in this Agreement) shall be paid
to Seller in cash or by wire transfer of other immediately available funds at the
consummation of the purchase and sale contemplated hereunder (the “Closing”).”

     4. Additional Deposit. The first sentence of Section 1.2(b)(2) of the Original
Agreement is hereby deleted in its entirety and the following is hereby substituted therefor:

“On or before September 28, 2006, Buyer shall deposit in escrow with the Title

     5. Adjustment to Broker’s Commissions. The second sentence of Section 6.1 of the
Original Agreement is hereby deleted in its entirety and the following is hereby substituted
therefor:

“At Closing, Buyer shall pay Seller’s Broker One Million Five Hundred Fifty Four
Thousand Seven Hundred Sixty Nine Dollars ($1,554,769), which amount equals the

have been waived.

     7. Changes to Estoppel Requirements. Section 8.4 of the Original Agreement is hereby
deleted in its entirety and the following is hereby substituted therefor:

          “Section 8.4 Estoppel Certificates.

          (a) Seller shall use commercially reasonable efforts to obtain estoppel
certificates from each tenant of the Property substantially in the form attached
hereto as Exhibit F (except with respect to the estoppel certificates to be
obtained from Health Net, Inc. [“Health Net”] and ATK Missile Systems Company, LLC
[“ATK”], as described below) or, if the Lease of a tenant (other than Health Net or
ATK) requires a different form, in the form required by such tenant’s Lease, or as
otherwise provided in this paragraph below. On or before September 19, 2006, Seller
shall submit to each tenant of the Property an estoppel certificate in the form of
said Exhibit F (except as otherwise provided below) and request that such
tenant sign and return such certificate to Seller within ten (10) days. It shall be
a condition to Buyer’s obligation to Close the sale and purchase of the Property
that on or before the Closing, Buyer is able to obtain an estoppel certificate (x)
substantially in such form attached hereto as Exhibit F-1 from Health Net,
(y) in exactly the form attached hereto as Exhibit F-3 from ATK, and (y)
substantially in such form attached hereto as Exhibit F from (i) three of
the following four tenants: Netzero, Inc., Poms & Associates Insurance Brokers,
Inc., Care Level Management, and Univision Music, LLC (each such Tenant, together
with Health Net and ATK, a “Major Tenant” and, collectively, the “Major Tenants”),
and (ii) from such other tenants of the Property, which, together with the Major
Tenants lease and occupy at least seventy-five percent (75%) of the area of the
Property actually rented to tenants (collectively, the “Estoppel Threshold”). All estoppel certificates shall be dated no more than thirty
(30) days prior to the Closing Date. An estoppel certificate (other than estoppel
certificates from Health Net and ATK which shall be in the forms of

2

 

Exhibit
F-1 and Exhibit F-3, respectively, as provided above), even though not
in the form of Exhibit F, will be deemed to be acceptable to Buyer (i) if it
is substantially on the standard form attached to the applicable tenant’s Lease (so
long as Buyer is not otherwise entitled to object thereto pursuant to Section 8.4(b)
below) and (ii) even if any tenant modifies or deletes Paragraph 13 from the
Exhibit F form returned by such tenant. If Seller is unable to satisfy the
Estoppel Threshold, Seller may (but is not required to) deliver estoppel
certificates in the form of Exhibit F-2 executed by Seller covering such
leases as are sufficient, when aggregated with the tenant estoppel certificates
previously delivered, to satisfy the Estoppel Threshold, provided that Buyer shall
not be obligated to accept Seller estoppel certificates that collectively cover in
excess of twenty percent (20%) of the area of the Property actually rented to
tenants or which are in lieu of an estoppel certificate for any of the Major
Tenants. Seller’s representations and warranties in any Seller estoppel
certificates will survive the Closing, subject to the limitations contained in
Sections 3.2, 3.3, 3.4, 9.11 and 9.19 hereof. In the event that Buyer receives an
estoppel certificate from a tenant complying with the requirements of this Section
8.4 and for which Seller previously delivered a Seller estoppel certificate in
accordance herewith, Seller shall be automatically released from any liability or
obligation under such Seller estoppel certificate, except with respect to those
provisions, if any, which materially conflict with the provision(s) covering the
same in the applicable Seller estoppel(s), provided, however, that all such
provisions shall still be subject to the limitations contained in Sections 3.2, 3.3,
3.4, 9.11 and 9.19 hereof.

          (b) If Seller is unable to obtain and deliver sufficient tenant estoppel
certificates in accordance with Section 8.4(a), or if the certificates received or
substituted Seller estoppels contain material information or omissions unacceptable
to Buyer in its reasonable discretion (it being agreed that any objection by Buyer
to any change made by ATK to the form of estoppel attached as Exhibit F-3
will be deemed reasonable) and Buyer objects thereto by written notice to Seller
within two (2) business days after receipt by Buyer of the objectionable estoppel,
then Seller will not be in default by reason thereof, and Seller may elect, by
written notice delivered to Buyer, to extend the Closing Date by up to thirty (30)
days in order to satisfy the requirement. If Seller still cannot satisfy the
requirement at the end of such extended period, then Buyer may, by written notice
given to Seller before the Closing (as so extended), elect to terminate this
Agreement and receive a refund of the Deposit or waive said condition. If Buyer so
elects to terminate this Agreement, the Deposit shall be returned to Buyer, and
neither party shall have any further rights or obligations hereunder except as
provided in Section 6.1 above and Sections 9.3 and 9.9 below. If no such
termination notice is delivered by Buyer, Buyer shall be deemed to have waived such
condition.

     8. Artwork Escrow and Artwork. Pursuant to the Assignment of Leases, Seller shall
assign to Buyer at Closing all of Seller’s right, title and interest in, to and under the portion
of that certain Escrow Holdback Agreement attached hereto as Exhibit J which pertains only
to the “Art Work Escrow Holdback Amount” and the “Art Work” (“Art Work Escrow”). Additionally, if
in connection with the completion of the Art Work Buyer after Closing incurs reasonable third party
out-of-pocket costs or expenses in excess of the sums which Buyer is entitled to withdraw from the
Art Work Escrow, Seller shall reimburse Buyer for all such excess costs and expenses within thirty
(30) days after Seller’s receipt of Buyer’s invoice therefor, but only to the extent that such
excess costs and expenses are not due to changes in scope or scale initiated by Buyer (it being
agreed that Seller’s reimbursement obligation hereunder shall specifically apply to any changes in
scope or scale legally required by the City of Los Angeles; provided, however, Seller may, at no
cost or expense to Buyer, contest any such changes in scope or scale legally required by the City
of Los Angeles). Pursuant to the Assignment of Leases, Buyer shall assume Seller’s
obligations under the contracts with Mark Lere/Poliquin Kellogg and with Poliquin Kellogg Design
Group, relating to the Art Work, which contracts are listed and described on Exhibit G
attached hereto. Seller’s reimbursement obligation hereunder shall be subject to the limitations
on

3

 

liability provided for in Sections 9.11 and 9.19 of the Agreement and shall survive the Closing
only for the Survival Period.

     9. Property Tax Escrow.

          (a) Establishment of Escrow. Notwithstanding the provisions of Section 1.2 of the
Agreement, at Closing, the Title Company shall withhold from the balance of the Purchase Price
otherwise payable to Seller pursuant to the Agreement the sum of One Million Three Hundred Thousand
Dollars ($1,300,000) (the “Property Tax Escrow”). The Property Tax Escrow shall be deposited by
the Title Company into an interest bearing account and all interest thereon, less investment fees,
if any, shall be deemed a part of the Property Tax Escrow for all purposes hereunder.

          (b) Property Tax Escrow Agreement. At Closing, Buyer, Seller and the Title Company
shall enter into a written escrow agreement, in form and substance reasonably acceptable to Buyer,
Seller and the Title Company (the “Property Tax Escrow Agreement”), which shall govern the holding
and disbursement of the Property Tax Escrow. The Property Tax Escrow Agreement will provide, in
pertinent part, that the Property Tax Escrow shall be disbursed to Buyer, Seller or a combination
of Buyer and Seller, strictly in accordance with the following terms:

          (i) If following the Closing, the various parcels, interests and other
components constituting the Property (including parking rights and other
entitlements and interests in and to parking garages, parking areas, common areas
and other portions of the project of which the Property is a part as set forth on
Exhibit I) are assessed or reassessed by the Los Angeles County Tax
Assessor, arising in whole directly from the sale of the Property to Buyer, with an
Aggregate Enrolled Tax Value (as defined below) that is:

	 	(A)	 	Greater than $314,250,000 (i.e., the Aggregate
Enrolled Tax Value exceeds $314,250,000, such excess defined as the
“Aggregate Excess Reassessment Amount”), then the Property Tax Escrow
will be disbursed as follows:

	 	(1)	 	First, Buyer shall be paid an amount equal to the product of:

     (x) the Property Tax Escrow,

     multiplied by

     (y) a fraction, the numerator of which is the
Aggregate Excess Reassessment Amount, and the
denominator of which is an amount equal to 98.7% of
the Association Enrolled Tax Value (as defined below)
for 2006/2007, which is valued by the Los Angeles
County Tax Assessor as $34,241,979 and as set forth
in Exhibit I.

	 	(2)	 	Second, the balance, if any, remaining
after the disbursement to Buyer under clause (1) above, shall
be disbursed to Seller, including any interest earned thereon.

	 	(B)	 	Less than or equal to $314,250,000, then the
entire Property Tax Escrow shall be returned to Seller, including any interest earned thereon.

For example, if such Aggregate Enrolled Tax Value is established by the Los

4

 

Angeles County Tax Assessor at $334,528,100 (i.e., Aggregate Excess
Reassessment Amount is $20,278,100), then $780,000 from the Property Tax
Escrow ($1,300,000 x [ $20,278,100/$33,796,833]) would be distributed to
Buyer, and the balance, including any interest earned thereon, would be
distributed to Seller.

          (ii) As used herein, the term “Aggregate Enrolled Tax Value” shall mean
the sum of (A) the enrolled assessed values of the five (5) Building Parcels (parcel
nos. 2149-019-001, 2149-019-002, 2149-019-009, 2149-019-015 and 2149-019-014)
identified on Exhibit I, plus (B) the product of (x) the Buyer’s Allocable
Share of the Common Assessment (as defined in the Master Declaration [as defined
below]), as of the Closing Date (i.e., 98.7%), multiplied by (y) the enrolled
assessed values of three (3) Association Parcels (parcel nos. 2149-019-003,
2149-019-013 and 2149-019-016) identified on Exhibit I (the sum of the
enrolled assessed values of these three (3) Association Parcels, the
“Association Enrolled Tax Value”). The determination of the Aggregate
Enrolled Tax Value shall be limited to any reassessments of the land and
improvements as of the Closing Date made within one (1) year following the Closing
Date, arising solely from the sale of Property from Seller to Buyer, and shall not
include any portion of reassessment attributable to (a) any additional improvements
made by Buyer, Declarant or other Association Members, on or to any Building Parcel
or Association Parcel included in Exhibit I, or (b) annual customary
inflationary increases (i.e. not to exceed 2.0%) of real estate taxes.

          (iii) As used herein, the term “Master Declaration” shall mean the
Master Declaration of Covenants, Conditions, Restrictions and Reservations of
Easements for LNR Warner Center and Termination of Former Declarations dated as of
May 22, 2003 (as amended and supplemented) to which the Property is subject, and
where LNR Warner Center, LLC is the Declarant.

          (iv) Notwithstanding anything to the contrary contained herein, no portion of
the Property Tax Escrow will be disbursed to Buyer or Seller until the Los Angeles
County Tax Assessor has reassessed the Property as of the Closing Date (including
all such parcels, interests and other components thereof) in connection with the
Closing and which reassessment must occur within one (1) year of the Closing Date
(x) such reassessment has become final and no longer subject to appeal or protest,
or (y) a period of eighteen (18) months has elapsed since such reassessment was
received by Buyer; provided that if no such reassessment occurs within one (1) year
of the Closing Date, the entire Property Tax Escrow shall be disbursed to Seller,
including any interest earned thereon.

          (c) Seller’s Right to Participate in Certain Tax Appeals and Protests. Buyer and
Seller confirm and agree that Seller shall have the right to participate (at Seller’s sole cost and
expense) in any tax protest, appeal, or inquiry relating to any reassessment of the value of the
Property after Closing based on the Purchase Price paid by Buyer at Closing and for which Buyer
claims a reimbursement from Seller hereunder; and that Buyer shall bring such tax
protest, appeal, or inquiry if so requested by Seller. Buyer shall provide written notice to
Seller within ten (10) business days of receipt of any and all such reassessments, and include
copies of all pertinent direct and supplemental tax bills in connection with any and all direct
assessments and such reassessments.

          (d) Miscellaneous. The provisions of this paragraph 9 shall survive Closing, and
neither the terms of this paragraph nor the Property Tax Escrow Agreement shall be subject to
the provisions of Section 9.19 of the Agreement; however, Seller’s liability under this paragraph 9
and under the Property Tax Escrow Agreement shall be limited to the amount of the Property Tax
Escrow. Additionally, any amounts paid to Buyer from the Property Tax Escrow shall not be taken
into account

5

 

for the purposes of determining the maximum liability of Seller under said Section
9.19 or any other provision of the Agreement, and the Property Tax Escrow shall not be counted
towards, or otherwise taken into account in determining, Seller’s satisfaction of its net worth
covenant under Section 9.20 of the Agreement.

     10. Amendments to Exhibits. Exhibit G to the Original Agreement is hereby
deleted in its entirety, and Exhibit G attached hereto is hereby substituted therefor.
Exhibit F-3, Exhibit I and Exhibit J attached hereto are hereby added as
new Exhibits to, and shall for all purposes become a part of, the Agreement.

     11. Property Management Office Build-Out License Agreement. Buyer and Seller hereby
acknowledge that they did not agree upon the form of license agreement prior to the expiration of
the Contingency Period as contemplated by Section 7.7 of the Agreement. Consequently, any exercise
by Buyer its right to commence the Office Build-Out Work pursuant Section 7.7 prior to Closing
shall be conditioned upon Buyer and Seller executing and delivering a license agreement in form and
content reasonably acceptable to the parties.

     12. Ratification. Except as herein modified or amended, all terms and conditions of
the Agreement are hereby ratified and confirmed by Seller and Buyer and remain in full force and
effect. In the event of any conflict between the terms and provisions of this Amendment and the
Agreement, this Amendment shall control.

     13. Multiple Counterparts. This Amendment may be executed in two or more
counterparts, each of which shall be deemed an original, but all of which taken together shall
constitute one and the same Amendment. This Amendment may also be executed by facsimile, and a
facsimile signature shall be deemed an original signature for all purposes.
