ITEM 5.   OTHER EVENTS.

On April 5, 1999 we closed a $115 million loan with Massachusetts Mutual Life
Insurance Company (The "MassMutual Loan"). The MassMutual Loan is secured by 12
properties, has a ten year term and bears interest at a fixed rate of 6.94%
(7.049% including the amortization of loan fees) and requires monthly payments
of principal and interest amortized over a 25 year period. Proceeds from this
loan were used to repay a portion of our lines of credit and certain other
variable-rate indebtedness.

Mortgage Loan No. 99701

                                 PROMISSORY NOTE

$115,000,000                                                      March 30, 1999

                                                         Los Angeles, California



FOR VALUE RECEIVED, ARDEN REALTY FINANCE V, L.L.C., a Delaware limited liability
company ("BORROWER"), promise(s) to pay to the order of MASSACHUSETTS MUTUAL
LIFE INSURANCE COMPANY ("LENDER"), at its home office in Springfield,
Massachusetts, or at such other place as Lender may direct, in lawful money of
the United States of America, without grace or offset, the principal sum of ONE
HUNDRED FIFTEEN MILLION AND NO/100 DOLLARS ($115,000,000), with interest thereon
at the rate of six and ninety-four one-hundredths percent (6.94%) per annum (the
"CONTRACT RATE") to be paid as provided herein below.

               This Promissory Note is secured by a Deed of Trust and Security
Agreement of even date herewith (collectively, the "MORTGAGE"), covering real
property and other property described in the Mortgage (collectively, the
"MORTGAGED PROPERTY").

        1. PAYMENT TERMS

               Payments shall be made on this Promissory Note as follows:

               A. On the date the loan evidenced hereby (the "LOAN") is made, a
payment of interest only shall be due and payable for the period from such date
to the first day of the next calendar month.

               B. Successive monthly installments of principal and interest,
shall be made on the first day of June, 1999 and on the first day of each
calendar month thereafter up to and including the first day of March, 2009 (each
a "PAYMENT DATE").

               C. Each monthly installment shall be in the constant amount of
EIGHT HUNDRED FIFTEEN THOUSAND NINE HUNDRED THIRTY-FOUR AND 98/100 DOLLARS
($815,934.98).


                                      -1-
<PAGE>   2







               D. A final installment equal to the entire principal balance then
remaining unpaid, with accrued interest thereon, shall be due and payable on
April 1, 2009 (the "MATURITY DATE");

               Unless otherwise directed by Lender in writing, all payments
shall be made by direct debit of Borrower's bank and bank account through
automated clearinghouse deductions of immediate federal funds or equivalent to
Lender's bank and bank account. Borrower acknowledges that, since the term of
the loan evidenced hereby is shorter than the amortization period, a substantial
portion of the principal balance will be due on the Maturity Date. Whenever any
payment to be made under this Promissory Note is stated to be due on a date
which is not a Business Day (defined herein below), the due date shall be
extended to the next succeeding Business Day and interest shall continue to
accrue and be payable at the applicable rate during such extension.

        2. INTEREST

               The monthly payments of combined principal and interest of this
Promissory Note are based upon a twenty-five (25) year amortization period, and
all interest accruing hereunder shall be calculated on the basis of a 360-day
year and the actual number of days elapsed.

        3. DEFAULT INTEREST

               If the entire unpaid principal balance of this Promissory Note,
together with accrued and unpaid interest thereon, is not paid when due, whether
on the Maturity Date or any earlier date as a result of acceleration of this
Promissory Note after an Event of Default (hereinafter defined), then the amount
unpaid shall bear interest from the Maturity Date or such earlier date, as the
case may be, at the per annum interest rate (the "DEFAULT RATE") equal to the
lesser of

                        (i)     the highest rate permitted by law to be charged
                                on a promissory note secured by a commercial
                                mortgage, or

                        (ii)    the sum of three percent (3%) plus the greater
                                of

                                (x)     the Contract Rate; or

                                (y)     the rate published in The Wall Street
                                        Journal as the average prime rate in its
                                        "Money Rates" section as of the Maturity
                                        Date or such earlier date. If The Wall
                                        Street Journal is not in publication on
                                        the applicable date, or ceases to

                                      -2-
<PAGE>   3

                                publish such average rates, then any other
                                publication acceptable to Lender quoting daily
                                market average prime rates will be used.



                                      -3-
<PAGE>   4





The Default Rate shall continue until the first to occur of the following:

                                (i)     payment in full of any sums due
                                        hereunder and under the Loan Documents
                                        (hereinafter defined); or

                                (ii)    reinstatement of the Loan pursuant to
                                        statutory provisions requiring such
                                        reinstatement, but only after the curing
                                        of all defaults and payments of all sums
                                        due hereunder.

        4. LATE CHARGE

               If any regular monthly installment of principal or interest due
hereunder, or any monthly deposit for taxes, ground rent, insurance,
replacements and other sums if required under any Loan Document, shall not be
paid as required under this Promissory Note or such Loan Document, as the case
may be, by the eleventh (11th) day of the month in which the same shall be due
or by the eleventh (11th) day after the due date for any payment other than the
regular monthly installment due under this Promissory Note, Borrower shall pay
to Lender a late charge (the "LATE CHARGE") of four cents ($0.04) for each
dollar so overdue in order to compensate Lender for its loss of the timely use
of the money and frustration of Lender in the meeting of its financial
commitments, and to defray part of Lender's incurred cost of collection
occasioned by such late payment. Lender agrees to comply with Section 2954.5 of
the California Civil Code (or any successor provision), as now or hereafter in
effect, with respect to the giving of notice prior to imposing a Late Charge.
Any Late Charge incurred shall be immediately due and payable. Nothing herein
contained shall be deemed to constitute a waiver or modification of the due date
of such installments or deposits or the requirement that Borrower make all
payment of installments and deposits as and when the same are due and payable.

        5. APPLICATION OF PAYMENTS

               Each payment received by Lender shall be applied in the following
order:

               A. First, to the interest due on any advances made by Lender
under any instrument which is a Loan Document;

               B. Next, to the principal amount of any advances made by Lender
under any instrument which is a Loan Document;


                                      -4-
<PAGE>   5







               C. Next, to Late Charges, attorneys' fees or any other amount due
hereunder or under a Loan Document save for the amounts described in (D) and (E)
immediately below;

               D. Next, to accrued interest due hereunder; and

               E. Finally, to the principal balance hereof.

               Notwithstanding the foregoing, in the event that Borrower does
not pay the outstanding principal balance and accrued interest due under this
Promissory Note, when due, whether on the Maturity Date or on any earlier date
as a result of acceleration of this Promissory Note, the Lender at its option
shall apply any payments it then receives in such order as Lender deems
appropriate in its sole discretion.

        6. EVENTS OF DEFAULT AND ACCELERATION

               The failure to make any payment required under this Promissory
Note, as and when due, and the failure to comply with any term, covenant or
condition of any Loan Document within the time provided therein, shall be an
event of default ("EVENT OF DEFAULT") hereunder.

               Upon the occurrence of an Event of Default subject to the terms
of Section 7, below, the Lender may, at any time thereafter, together or singly,

                        (i)  declare the entire outstanding principal balance
                             due hereunder, together with all accrued and unpaid
                             interest thereon, to be immediately due and
                             payable, thereby accelerating this Promissory Note;

                        (ii) exercise immediately and without notice, any and
                             all other rights and remedies available under the
                             Loan Documents or at law or in equity.

        7. NOTICE AND CURE 

               Prior to accelerating this Promissory Note for an Event of
Default or exercising any rights or remedies as to which acceleration is a
precondition, Lender shall give Borrower notice specifying the Event of Default
and time to cure such Event of Default, as follows, but not otherwise:

A. If the Event of Default is one which can be cured by the mere payment of
money (other than a failure to keep in effect insurance required under any of
the Loan Documents and other than as described in Section 7B(i) below),


                                      -5-
<PAGE>   6





                Borrower shall have ten (10) days from the notice of Event of
Default to pay such money and to cure and eliminate the Event of Default;

               B. If the Event of Default is

                     (i)    the failure to pay on the Maturity Date the
                            outstanding principal balance, accrued interest, and
                            other payments due under this Promissory Note or the
                            Loan Documents;

                     (ii)   the failure to have or keep in force insurance as
                            required under any of the Loan Documents;

                     (iii)  the insolvency, or bankruptcy of the Borrower, or
                            any guarantor hereof;

                     (iv)   a sale, transfer or encumbrance of a direct,
                            indirect, legal or beneficial interest in the
                            Borrower (including, without limitation, any direct
                            or indirect interest in the owner of any legal or
                            beneficial interest in Borrower) or the property
                            encumbered by the Loan Documents for which any
                            required approval of Lender under any Loan Document
                            was not obtained;

               Borrower shall not be entitled to any notice of Event of Default,
or time to cure, and Lender shall not be obligated to give the same.

               C. If the Event of Default is one which cannot be cured by the
mere payment of money (other than an Event of Default described in Section 7B
above), Borrower shall have thirty (30) days from the notice of Event of Default
to cure and eliminate the Event of Default.

               D. The Lender's agreement to give notice and time to cure are on
the further conditions that:

                     (i)    the failure of Lender to give any notice(s) required
                            shall not result in the imposition of any
                            liabilities or penalties upon Lender;

                     (ii)   the agreement to give notice and time to cure is
                            personal to Borrower, and does not extend to or vest
                            any such rights in any other person or entity; and


                                      -6-
<PAGE>   7







                     (iii)  nothing contained in this Section 7 shall prevent
                            the imposition of Late Charges, or the right of the
                            Lender to exercise immediately and, without notice,
                            any and all other rights and remedies available
                            under the Loan Documents or at law or in equity.

        8. DEFINITIONS

               Any terms used in this Promissory Note requiring a definition
shall have the definition given in this Section, unless elsewhere defined in
this Promissory Note. Any and all instruments securing or executed in connection
with this Promissory Note, including, without limitation, the Mortgage,
guarantees, indemnities, pledges, master leases, security agreements and
assignments of leases and rents are herein collectively referred to as the "LOAN
DOCUMENTS." Any instrument included within the term "Loan Documents" is herein
referred to in the singular as a "Loan Document." Any capitalized terms used in
this Promissory Note and not defined herein (including without limitation the
terms "COLLATERAL", "DEBT SERVICE COVERAGE RATIO", "EQUIPMENT", "INDEBTEDNESS",
"LOAN TO VALUE", "LOSSES", "MORTGAGED PROPERTY", "PROCEEDS", "PREMISES",
"PROPERTY INCOME" and "SINGLE PURPOSE ENTITY") shall have the meaning set forth
for such in the Mortgage. The term "Event of Default" shall have the meaning
given in Section 6 hereof. The term "BUSINESS DAY" as used herein shall mean any
day other than a Saturday, Sunday or other day on which national banks in the
State of California are not open for business.

        9. PREPAYMENT

               There are no full or partial prepayment privileges of the
principal amount due under this Promissory Note except as follows:

               9.1 Prepayment in Full. Borrower shall have the right to make
payment in full, but not in part, of the then outstanding principal balance
hereof, on any payment date on and after (but not prior to) the fifth
anniversary of the due date of the first monthly installment payment required
under Section 1A, provided that Borrower gives Lender thirty (30) days prior
written notice of its intention to make any such prepayment, the date thereof,
and the amount to be prepaid, and that Borrower also pays, as consideration for
the privilege of making such prepayment, a prepayment premium (the "PREPAYMENT
PREMIUM") calculated as follows:

       The Prepayment Premium shall be equal to the greater of (x) or (y), where


                                      -7-
<PAGE>   8







               (x) is equal to the amount to be prepaid multiplied by one 
               percent (1%); and

               (y) is equal to the product (discounted as hereinafter provided)
               obtained by multiplying the amount to be prepaid by the
               "Prepayment Premium Rate." The "PREPAYMENT PREMIUM RATE" shall be
               the percentage obtained by multiplying the excess, if any, of the
               Contract Rate over the market yield of U.S. Treasury issues which
               have the closest maturity (month and year) to the Maturity Date,
               as quoted in The Wall Street Journal published on the scheduled
               prepayment date, by a fraction, the numerator of which is equal
               to the number of days remaining from and including the scheduled
               prepayment date to and including the Maturity Date, and the
               denominator of which is 360. Should more than one U.S. Treasury
               issue be quoted as maturing on the date closest to the Maturity
               Date, then the issue having the market yield which differs least
               from the Contract Rate will be used in the calculations. If The
               Wall Street Journal is not in publication on the applicable date,
               or ceases to publish such U.S. Treasury issue yield, then any
               other publication acceptable to Lender quoting daily market
               yields for U.S. Treasury issues will be used. The product
               obtained from the foregoing shall then be discounted, on a
               semi-annual basis over the remaining term of this Promissory
               Note, as of the date of prepayment to its then present value,
               using the U.S. Treasury yield, referred to in this subparagraph
               (y).

               9.2 Prepayment Upon Partial Release of Mortgaged Property.
Borrower shall make prepayment (with Prepayment Premium) in connection with
partial reconveyances of properties encumbered by the Mortgage, in accordance
with Section 6.13 of the Mortgage.

               9.3 General Prepayment Provisions.

               A. No Prepayment Premium shall be required to be paid on or after
or in connection with payment of fire, casualty, or condemnation proceeds to the
Lender in accordance with the provisions of the Mortgage.

               B. There will be due, with any prepayment of principal, all
accrued and unpaid interest thereon, in addition to all other amounts due under
this Promissory Note.

                                      -8-
<PAGE>   9

               C. If the maturity of this Promissory Note is accelerated by the
Lender because of the occurrence of an Event of Default, the resulting
acceleration shall be deemed to be an election on the part of Borrower to prepay
the Loan. Accordingly, there shall be added to the amount due after an Event of
Default and resulting acceleration, a Prepayment Premium, calculated as above
and using as the prepayment date the date on which any tender of payment is
made, and the Borrower agrees to pay the same. Any tender of payment made after
acceleration by or on behalf of Borrower (including, without limitation, payment
by any guarantor or purchaser at a foreclosure sale), shall include the
Prepayment Premium computed as provided herein. In the event such Event of
Default, acceleration and tender occur prior to the time Borrower may prepay the
Loan, under Paragraph A above, there shall nevertheless be due and added the
Prepayment Premium calculated in the manner set forth in said Paragraph A as
though such prepayment privilege were in effect.

BORROWER BY ITS SIGNATURE BELOW HEREBY EXPRESSLY (i) WAIVES ANY RIGHTS IT MAY
HAVE UNDER CALIFORNIA CIVIL CODE SECTION 2954.10 TO PREPAY THIS PROMISSORY NOTE,
IN WHOLE OR IN PART, WITHOUT PENALTY, UPON ACCELERATION OF THE MATURITY DATE,
AND (ii) AGREES THAT IF, FOR ANY REASON, A PREPAYMENT OF ALL OR ANY PORTION OF
THE PRINCIPAL AMOUNT OF THIS PROMISSORY NOTE IS MADE UPON OR FOLLOWING ANY
ACCELERATION OF THE MATURITY DATE BY LENDER ON ACCOUNT OF ANY DEFAULT BY
BORROWER INCLUDING, WITHOUT LIMITATION, ANY TRANSFER, DISPOSITION, OR FURTHER
ENCUMBRANCE PROHIBITED OR RESTRICTED BY THE DEED OF TRUST SECURING THIS
PROMISSORY NOTE, THEN BORROWER SHALL BE OBLIGATED TO PAY CONCURRENTLY WITH SUCH
PREPAYMENT, THE PREPAYMENT PREMIUM SPECIFIED IN THE FOREGOING PARAGRAPHS. BY
SIGNING THIS PROVISION IN THE SPACE PROVIDED BELOW, BORROWER HEREBY DECLARES
THAT LENDER'S AGREEMENT TO MAKE THE LOAN EVIDENCED BY THIS PROMISSORY NOTE
CONSTITUTES ADEQUATE CONSIDERATION, GIVEN INDIVIDUAL WEIGHT BY BORROWER FOR THIS
WAIVER AND AGREEMENT.

               BORROWER'S SIGNATURE:___________________________

               D. The Prepayment Premium herein provided for represents the
reasonable estimate of Lender and Borrower of a fair average compensation for
the loss that will be sustained by Lender resulting from the payment of the
outstanding 


                                      -9-
<PAGE>   10

principal balance of the loan evidenced hereby prior to the Maturity Date. The
Prepayment Premium shall be paid without prejudice to the right of Lender to
collect any other amounts provided to be paid under this Promissory Note, or
under the other Loan Documents, or pursuant to the provisions of law.

               E. No Prepayment Premium shall be required to be paid with
respect to a prepayment made during the last three (3) months of the originally
scheduled term of the Loan.

        10.WAIVERS AND EXTENSIONS

               Borrower and all endorsers and guarantors and any and all others
who may at any time be or become liable for payment of all or any part of the
Loan severally waive presentment for payment, demand, notice of dishonor or
nonpayment, protest and notice of protest, notice of acceleration and of
intention to accelerate the Maturity Date (except as provided in Section 7,
above) and any and all lack of diligence or delays in collection or enforcement
hereof, and agree that Lender from time to time may extend the time for payment
of any sums due under this Promissory Note and grant releases to all endorsers
and guarantors hereof, and may release all or any portion of the Mortgaged
Property, without in any way affecting the liability of such parties hereunder.

        11.LIMITATIONS ON LIABILITY

               A. In any action or proceeding brought on this Promissory Note or
on the Mortgage or on any of the Loan Documents in which a money judgment is
sought (subject to paragraphs B, C, and D below), Lender will look solely to the
Mortgaged Property described in the Loan Documents (including, without
limitation, the Collateral) for payment of the Indebtedness and, specifically
and without limitation, Lender agrees to waive any right to seek or obtain a
deficiency judgment against Borrower or to seek or obtain a personal judgment
for the payment of money representing principal or interest of the Loan.

               B. The provisions of this Section 11 shall not

                     (i)    except as set forth herein, constitute a waiver,
                            release or impairment of any obligation evidenced or
                            secured by this Promissory Note, the Mortgage or any
                            other Loan Document;

                     (ii)   be deemed to be a waiver of any right which Lender
                            may have under Sections 506(a), 506(b), 1111(b) or
                            any other provisions of the U.S. Bankruptcy Code to


                                      -10-
<PAGE>   11

                            file a claim for the full amount of the Indebtedness
                            secured by the Mortgage or to require that all
                            Collateral shall continue to secure all of the
                            Indebtedness owing to the Lender in accordance with
                            the Promissory Note, the Mortgage and the other Loan
                            Documents;

                     (iii)  impair the right of Lender to name Borrower or any
                            guarantor of this Promissory Note, as a party or
                            parties defendant in any action or suit for judicial
                            foreclosure and sale under the Mortgage (but no
                            personal judgment for a deficiency money judgment
                            may be entered or enforced against Borrower);

                     (iv)   affect the validity or enforceability of, or limit
                            recovery under, any indemnity (including, without
                            limitation, any environmental indemnity set forth in
                            the Mortgage or other Loan Document, or any separate
                            environmental indemnity agreement, however
                            designated), guaranty, lease or similar instrument
                            made in connection with this Promissory Note, the
                            Mortgage, or the Loan Documents;

                     (v)    impair the right of Lender to obtain the appointment
                            of a receiver; or

                     (vi)   impair the enforcement of an assignment of leases or
                            an assignment of rents contained in the Mortgage or
                            any separate Assignments of Leases and Rents
                            executed in connection herewith.

               C. Notwithstanding any provisions of this Section 11 to the
contrary, nothing herein shall be deemed to prejudice the right of Lender (which
right is specifically reserved) to pursue or obtain personal recourse liability
against the Borrower, or any other person or entity, to recover Losses incurred
by Lender, arising out of, or resulting from:

                     (i)    fraud or material misrepresentation in connection
                            with any Loan Document, affidavit, certification,
                            warranty or representation given by Borrower or any
                            officer, general partner, principal, member, or
                            authorized agent

                            of Borrower, in connection with the obtaining or
                            making of the loan evidenced by this Promissory
                            Note;

                     (ii)   the application or appropriation of any condemnation
                            or insurance proceeds in a manner contrary to the
                            terms of the Loan Documents;

                     (iii)  the application or appropriation of any tenant
                            security deposits, advance or prepaid rents,
                            cancellation or termination fees funds in required
                            reserve accounts or escrow accounts or other similar
                            sums paid to or held by Lender, Borrower, any escrow
                            holder or depository or any other person in
                            connection with the operation of the Premises in a
                            manner contrary to the terms of the Loan Documents;

                     (iv)   the failure to return, or reimburse Lender for, all
                            Equipment taken from the Mortgaged Property by or on
                            behalf of Borrower and not replaced with Equipment
                            of the same utility;

                     (v)    any act of arson or malicious destruction or waste
                            by Borrower, any principal, affiliate or partner
                            thereof, or by any guarantor or indemnitor
                            (including any indemnitor under the environmental
                            indemnity contained in the Mortgage, or in a
                            separate environmental indemnity or similar document
                            executed herewith); or

                     (vi)   the failure to apply Property Income or Proceeds to
                            payments due under the Loan Documents or to
                            operating expenses of the Mortgaged Property,
                            thereby resulting in, or contributing materially to,
                            an Event of Default; provided, however, that
                            Borrower shall have no recourse liability for Losses
                            based on distributions of Property Income or rent
                            loss insurance Proceeds to Borrower, or any general
                            partner, principal, stockholder, or member of or
                            managing agent for Borrower, made in good faith
                            (after determining the sufficiency of Property
                            Income and rent loss insurance Proceeds to cover the
                            payments due under the Loan 


                                      -12-

                            Documents and operating expenses of the Mortgaged
                            Property) prior to an Event of Default.

               D. Notwithstanding the foregoing, the agreement of Lender not to
pursue personal recourse liability against Borrower as set forth in this Section
11 above SHALL AUTOMATICALLY BECOME NULL AND VOID as to Borrower and shall be of
no further force and effect in the event (i) Borrower, any general partner or
member of Borrower, or any guarantor of the Loan, files, or consents to the
filing of, any petition under the U.S. Bankruptcy Code respecting its or their
debts or (ii) any such petition shall have been filed against the Borrower, any
general partner or member of the Borrower, or any guarantor of this Promissory
Note, and the same is not dismissed within ninety (90) days of such filing, or
(iii) Borrower makes a transfer of the Mortgaged Property or any portion thereof
or interest therein or encumbers the Mortgaged Property or any portion thereof
or interest therein in violation of the Loan Documents, or (iv) Borrower fails
to maintain its status as a Single Purpose Entity.

        12.USURY

               No amounts under this Promissory Note or the Loan Documents shall
be charged, paid or collected from Borrower if the result of such charge payment
or collection would be to cause the Loan to be usurious under applicable law.
If, however, an amount is paid or collected which would otherwise cause the Loan
to be usurious, such excess causing the Loan to be usurious shall be deemed a
payment of principal and shall be applied against and shall reduce the then
outstanding principal balance of the Loan by a corresponding amount, and no
Prepayment Premium shall be charged on any such excess amount applied to
principal.

        13.TRANSFERS

               Upon the transfer of this Promissory Note, Borrower hereby
waiving notice of any such transfer, Lender may deliver all the Loan Documents,
Proceeds, Property Income or Collateral, or any part hereof, to the transferee
who shall thereupon become vested with all rights herein, or under applicable
law, given to Lender with respect thereto, and Lender shall thereafter forever
be relieved and fully discharged from any liability or responsibility under or
with respect to this Promissory Note, and the Loan Documents, Proceeds, Property
Income and Collateral so transferred; but Lender shall retain all rights hereby
given to it with respect to any obligations of the Borrower and the Loan
Documents, Proceeds, Property Income or Collateral not so transferred. Upon any
such transfer, the term "Lender" as used herein shall mean such transferee.

                                      -13-
<PAGE>   14

        14.SEVERABILITY

               In the event any one or more of the provisions contained in this
Promissory Note or the Loan Documents shall for any reason be held to be
invalid, illegal or unenforceable in any respect, such invalidity, illegality or
unenforceability shall not affect any other provision of this Promissory Note or
of the Loan Documents, but this Promissory Note and the Loan Documents shall be
construed as if such invalid, illegal or unenforceable provision had never been
contained herein or therein.

        15.WAIVER OF TRIAL BY JURY

               BORROWER AND LENDER, BY ACCEPTANCE OF THIS PROMISSORY NOTE,
HEREBY WAIVE TRIAL BY JURY IN ANY COURT ACTION, PROCEEDING OR COUNTERCLAIM
WHETHER IN CONTRACT, TORT OR OTHERWISE, RELATING DIRECTLY OR INDIRECTLY TO THE
LOAN EVIDENCED BY THIS PROMISSORY NOTE, ANY APPLICATION FOR THE LOAN EVIDENCED
BY THIS PROMISSORY NOTE, THIS PROMISSORY NOTE, THE MORTGAGE OR THE LOAN
DOCUMENTS OR ANY ACTS OR OMISSIONS OF LENDER, ITS OFFICERS, EMPLOYEES, DIRECTORS
OR AGENTS IN CONNECTION THEREWITH.

        16. JOINT AND SEVERAL LIABILITY.

               If there shall be more than one (1) Borrower named in this
Promissory Note, then the obligations and liabilities of such parties as
Borrower shall be joint and several.

        17.REMEDIES CUMULATIVE

               The rights, powers and remedies of Lender permitted by law,
equity or contract or as set forth herein or in the Loan Documents shall be
cumulative and concurrent, and may be pursued singly, successively or together
against Borrower or the Mortgaged Property, the Collateral or the Property
Income, at the sole discretion of the Lender, and to the fullest extent
permitted by law. Such rights, powers and remedies shall not be exhausted by any
exercise thereof but may be exercised as often as occasion therefor shall occur.
The failure to exercise any such right, power or remedy shall in no event be
construed as a waiver or release of the same. Lender shall not by any act of
omission or commission be deemed to have waived any of its rights, powers or
remedies under this Promissory Note or the Loan Documents unless such waiver be
in writing and signed by Lender, and then `only to the extent specifically set
forth therein. A waiver of a right in one 


                                      -14-
<PAGE>   15

event shall not be construed as continuing or as a bar, or as a waiver of such
right on a subsequent event.

        18.FEES AND COSTS

               Borrower further promises to pay upon demand all reasonable
attorneys' fees and costs (including, without limitation, court costs and
appraisal fees) incurred by Lender in connection with any Event of Default under
this Promissory Note and in any proceeding, including all appeals, brought to
enforce any of the provisions of this Promissory Note or of the Loan Documents.

        19.TIME OF THE ESSENCE

               Time shall be of the essence in performance of all obligations of
Borrower under this Promissory Note and the Loan Documents including, without
limitation, the time periods provided for the curing of defaults.

        20.HEADINGS FOR CONVENIENCE

               Headings and captions used in this Promissory Note are inserted
for convenience of reference only and neither constitute a part of this
Promissory Note nor are to be used to construe or interpret any of the
provisions hereof.

        22.NO ORAL CHANGE

               This Promissory Note may not be modified, amended, waived,
extended, changed, discharged or terminated orally or by any act or failure to
act on the part of the Borrower or Lender, but only by an agreement in writing,

        23.APPLICABLE STATE LAW

               This Promissory Note shall be governed, construed, applied and

        24.SALE OF LOAN

               Lender, in the management of its investments or for any other
reason, may, at any time, sell, transfer or assign this Promissory Note, the
Mortgage and the other Loan Documents and the servicing rights with respect
thereto or grant participations therein or issue mortgage pass-through
certificates or other securities evidencing a beneficial interest in the Note,
Mortgage and other Loan Documents (collectively, a "TRANSFER"). A transfer may
include a sale of the 


                                      -16-
<PAGE>   17

whole Loan, or interests in the Loan, or a pooling of the Loan with other loans
in connection with a sale of public or private securities backed by the pool of
loans (each, a "SECONDARY MARKET TRANSACTION"). As part of a Transfer, Lender
may forward to each transferee, assignee, servicer, participant or investor all
documents and information which Lender now has or may hereafter acquire relating
to the Indebtedness, the Loan Documents and the Mortgaged Property. Subject to
the provisions of Section 25, below, Borrower agrees to cooperate with Lender in
connection with a Transfer including, without limitation, the delivery of any
estoppel certificates required under Section 2.18 of the Mortgage and such other
documents as may be reasonably requested by Lender. Borrower acknowledges and
agrees that, in connection with a Secondary Market Transaction, Lender may make
such information regarding Borrower and the Mortgaged Property and any other
matter related to the making of the Loan available to potential purchasers or
investors and, if applicable, rating agencies and their respective advisors,
subject, however, to the confidentiality provisions contained in Section 25
below. Borrower agrees to take such actions as may be reasonably requested by
Lender or any proposed assignee or participant of Lender in order to facilitate
any such assignment, transfer or participation, including without limitation
execution and delivery of one or more substitute promissory notes reallocating
the Indebtedness hereunder (on the same terms and conditions) among Lender and
any such assignees of Lender.

                      (a) Borrower has fee simple title (or such lesser estate

           indefeasible title to the


                                       11
<PAGE>   16





           balance of the Mortgaged Property, free and clear of liens and
           encumbrances except Permitted Encumbrances.

                      (b) Borrower has full power and lawful authority to

           enforceable lien on and security interest in the Mortgaged Property.

                      (d) Borrower will preserve such title and will forever
           warrant and defend the same and the validity and priority of the lien
           hereof to Trustee and Lender against all claims whatsoever.

               Section 2.3 Maintenance of the Mortgaged Property. Borrower shall
maintain the Mortgaged Property in good and safe condition, working order and
repair, ordinary wear and tear excepted, and comply in all material respects

affecting the Mortgaged Property. Borrower shall permit Lender to enter upon and
inspect the Mortgaged Property upon prior notice at all reasonable hours, but
subject to the rights of tenants. Borrower shall not, without the prior consent
of Lender, (a) change the use of the Premises or cause or permit the use or
occupancy of any part of the Premises to be discontinued if such discontinuance
would violate any zoning or other law, ordinance or regulation; (b) consent to
any zoning reclassification, modification or restriction affecting the Premises;
(c) threaten, commit or permit any waste, structural or material alteration

Equipment included within the Collateral may be removed if replaced with similar
items of equal or greater value); or (d) take any steps whatsoever to convert
the Mortgaged Property, or any portion thereof, to a condominium or cooperative
form of ownership. No provision of this Section 2.3 shall prohibit Borrower from
undertaking and completing tenant improvement work authorized under Leases
previously approved by Lender or not requiring Lender's prior approval, or
alteration, demolition or removal of Mortgaged Property in connection with
restoration or condemnation in accordance with Sections 2.4 and 2.5.

               Section 2.4   Insurance; Restoration.

                      (a) Borrower shall keep the Improvements and the Equipment
           insured against damage by fire and the other hazards (excluding
           earthquake and flood) covered by a comprehensive all risk coverage
           insurance policy, in an amount equal to one hundred percent (100%) of
           the full insurable value thereof 


                                       12
<PAGE>   17

           (which shall mean the full repair and actual replacement value
           thereof providing for no deductible in excess of Twenty-Five Thousand
           Dollars ($25,000), without reduction for depreciation or
           co-insurance) as approved by Lender, and against loss of rents in an
           amount not less than twelve (12) months' rental income from all
           Leases. Borrower shall also keep the Improvements and the Equipment
           insured against flood, earthquake and earth movement, as long as such
           insurance is available at commercially reasonable premiums (it being
           acknowledged that the premiums beings charged for such insurance as
           of the date of this Deed of Trust are commercially reasonable).
           Borrower shall also carry such other insurance, and in such amounts,
           as Lender may from time to time reasonably require, against insurable
           risks which at the time are commonly insured against in the case of
           premises similarly situated, due regard being given to the
           availability of insurance and to the type of construction, location,
           utilities, use and occupancy of the Premises or any replacements or
           substitutions therefor. Such additional insurance may include
           workers' compensation, boiler and machinery, flood, earthquake,
           demolition and contingent liability from the operation of
           "non-conforming" improvements on the Premises, and shall be obtained
           within twenty (20) days after demand by Lender. Borrower shall not
           obtain any umbrella or blanket liability or casualty policy or any
           separate or additional insurance which is contributing in the event
           of loss. Notwithstanding the foregoing, in the event Borrower obtains
           an umbrella or a blanket insurance policy or a separate policy or any
           other insurance policy affecting the Mortgaged Property hereunder,
           Borrower shall notify Lender of the same and at the request of Lender
           shall cause certified copies of each insurance policy to be delivered
           as required under Section 2.4(c) below. Any umbrella or blanket
           insurance policy shall specifically allocate to the Mortgaged
           Property the amount of coverage from time to time required hereunder
           and shall otherwise provide the same protection as would a separate
           policy insuring only the Mortgaged Property in compliance with the
           provisions of Section 2.4(c), giving Lender all of the rights set
           forth in this Section 2.4. The Proceeds of insurance paid on account
           of any damage to or destruction of the Premises or any portion
           thereof shall be paid over to Lender to be applied as hereinafter
           provided.

                      (b) Borrower shall also maintain public liability
           insurance with respect to the Premises against personal injury, death
           and property damage, with limits of liability in amounts satisfactory
           to Lender in its sole discretion.

                      (c) All insurance policies and endorsements required
           pursuant to this Deed of Trust shall (i) be endorsed to name Lender
           as an insured thereunder, as its interest may appear, with loss
           payable to Lender, without contribution, under a long-form,
           non-contributory mortgagee clause, or otherwise endorsed as Lender
           may reasonably require; (ii) be fully paid for and contain such
           provisions and expiration dates and be in such form and issued by
           such insurance companies 


                                       13
<PAGE>   18

           licensed to do business in the State as shall be approved by Lender,
           and shall have a rating of "A-VIII" or better as established by
           Best's Rating Guide (or an equivalent rating with such other
           publication of a similar nature as shall be in current use) and a
           rating of long-term unsecured debt obligations of at least "AA" by
           Standard & Poor's Rating Services, a division of The McGraw Hill
           Companies, Inc.; (iii) without limiting the foregoing, provide that
           such policy or endorsement may not be canceled or materially changed
           except upon thirty (30) days prior written notice of intention of
           non-renewal, cancellation or material change to Lender, and that no
           act or thing done by Borrower or Lender shall invalidate the policy
           as against Lender; (iv) have a minimum term of twelve (12) months and
           (v) be in form and content satisfactory to Lender. Lender
           acknowledges that the insurance policies and endorsements provided to
           Lender on the date hereof comply with the requirements of this
           Section. Borrower shall not finance any insurance policies required
           hereunder, or any premiums payable in connection therewith. Borrower
           shall deliver all original policies including all endorsements and
           renewals thereof, or copies thereof certified by the insurance
           company or authorized agent as being true copies, to Lender together
           with all endorsements required hereunder, on the date of this Deed of
           Trust and thereafter at least ten (10) days prior to the expiration
           date of such policies. Borrower may request an extension of time not
           exceeding one hundred twenty (120) days to deliver the foregoing
           policies, endorsements and renewals or certified copies thereof if
           Borrower has done all things necessary to obtain the issuance of the
           policies, endorsements and renewals including, without limitation,
           the payment of all premiums therefore, and Borrower has delivered to
           Lender within the above ten (10) day period an insurance binder
           satisfactory to Lender issued by the approved insurer showing all
           required coverage to be in full force and effect for the succeeding
           twelve (12) month period along with evidence satisfactory to Lender
           of payment in full of all premiums. If Borrower fails to maintain
           insurance in compliance with this Deed of Trust, Lender may (but
           shall not be obligated to) obtain such insurance and pay the premium
           therefor and Borrower shall reimburse Lender on demand for all such
           Advances. Notwithstanding anything to the contrary contained herein
           or in any provision of law, the Proceeds of insurance policies coming
           into the possession of Lender shall not be deemed trust funds and
           Lender shall be entitled to dispose of such Proceeds as hereinafter
           provided.

                      (d) In the event of any damage to or destruction of the
           Premises and/or Equipment the repair of which would cost in excess of
           $100,000, Borrower shall give prompt written notice to Lender and
           shall promptly commence and diligently continue to completion the
           repair, restoration and rebuilding of the Premises and/or Equipment
           so damaged or destroyed in full compliance with all legal
           requirements and with the provisions of Section 2.4(h)(i) below, and
           free and 


                                       14
<PAGE>   19

           clear from any and all liens and claims. Such repair, restoration and
           rebuilding of the Premises are sometimes hereinafter collectively
           referred to as the "WORK." Borrower shall not adjust, compromise or
           settle any claim for casualty insurance proceeds without the prior
           consent of Lender. Lender shall have the option in its sole
           discretion (subject to Section 2.4(g) and (i)) to apply any casualty
           insurance Proceeds it may receive pursuant to this Deed of Trust
           (less any cost to Lender of recovering and paying out such Proceeds,
           including reasonable attorneys' fees) to the payment of the
           Indebtedness or to allow all or a portion of such Proceeds to be used
           for the Work. If any insurance Proceeds are applied to reduce the
           Indebtedness, provided no Event of Default shall have occurred and be
           continuing, Lender shall apply the same, without any prepayment fee,
           in the following order:

                                 (i) first, to the payment of interest due on
                      any Advances;

                                 (ii) next, to the principal amount of any
                      Advances;

                                 (iii) next, to any Late Charges, attorneys'
                      fees or any other amount due hereunder or under a Loan
                      Document save for the amounts described in (iv) and (v)
                      immediately below;

                                 (iv) next, to accrued interest then due under
                      the Note; and

                                 (v) finally, to the unpaid principal balance of
                      the Note (in the inverse order of maturity of principal
                      installments thereof).

                      If an Event of Default shall have occurred and be
                      continuing, however, Lender, at its option, may apply any
                      insurance Proceeds to the foregoing items in such order
                      and priority as Lender deems appropriate in its sole
                      discretion.

                      (e) In the event of the foreclosure of this Deed of Trust
           or other transfer of title to or assignment of the Mortgaged Property
           in extinguishment of the Indebtedness in whole or in part, all right,
           title and interest of Borrower in and to all policies of insurance
           required by this Deed of Trust and any insurance Proceeds shall inure
           to the benefit of and pass to Lender or any purchaser or transferee
           at the foreclosure sale of the Mortgaged Property.

                      (f) Borrower hereby irrevocably appoints Lender its
           attorney-in-fact, coupled with an interest, to apply and make claims
           for casualty insurance Proceeds under all insurance policies
           constituting Intangibles, to prosecute and settle such claims and to
           endorse any checks, drafts or other instruments representing any
           casualty insurance Proceeds whether payable by reason of loss
           thereunder or otherwise. Additionally, Lender may notify any and all
           insurers 


                                       15
<PAGE>   20

           under casualty and liability insurance policies constituting part of
           the Intangibles that Lender has a security interest pursuant to the
           provisions of this Deed of Trust in and to such insurance policies
           and any proceeds thereof, and that any payments under those insurance
           policies are to be made directly to Lender. Lender's rights under
           this Section 2.4(f) may be exercised by Lender or a court appointed
           receiver appointed upon the request of Lender and irrespective of
           whether or not a default shall have occurred under this Deed of
           Trust.

                      (g) Notwithstanding the provisions of Section 2.4(d)
           above, Lender shall, upon request by Borrower, permit Borrower to use
           the Proceeds for the Work (subject to the provisions of, and less
           Lender's costs described in, Section 2.4(h) below), so long as:

                                 (i) no Event of Default which permits
                      acceleration of the Loan shall have occurred and be
                      continuing;

                                 (ii) the original Borrower named herein
                      continues to be the owner of the portion of Mortgaged
                      Property in question;

                                 (iii) the Work can be completed within twelve
                      (12) months from the date of the damage to or destruction
                      of the Premises and Lender determines in its reasonable
                      judgment that the cost of the Work shall not exceed fifty
                      percent (50%) of the Allocated Loan Amount for the portion
                      of the Mortgaged Property in question;

                                 (iv) none of the Leases in effect immediately
                      prior to the damage or destruction shall have been
                      canceled or terminated nor shall any such Leases contain
                      any still exercisable right to cancel, as a result of such
                      damage or destruction;

                                 (v) all sums necessary to effect the Work over
                      and above any available Proceeds shall be at the sole cost
                      and expense of the Borrower and, at Lender's request,
                      Borrower shall deposit such additional amounts, as
                      estimated by Lender in its sole discretion, with Lender
                      prior to commencing any Work and at all times thereafter;

                                 (vi) at all times during any such Work Borrower
                      shall maintain, at its sole cost and expense, workers'
                      compensation, builders' risk and public liability
                      insurance in amounts satisfactory to Lender and in
                      accordance with the provisions of this Section 2.4; and

                                 (vii) any unexpended casualty insurance
                      Proceeds, at the sole option of the Lender, shall either
                      be paid over to the Borrower or 


                                       16
<PAGE>   21

                      shall be applied to the reduction of the Indebtedness, but
                      any unexpended amounts of any additional deposit shall be
                      returned to Borrower upon completion of the Work. If the
                      Proceeds are used to reduce the Indebtedness, they shall
                      be applied in the order provided in Section 2.4(d),
                      without any prepayment fee.

                      (h) If any insurance Proceeds are used for the Work, then
           such Proceeds shall be held by Lender and shall be paid out from time
           to time to Borrower as the Work progresses (less any cost to Lender
           of recovering and paying out such Proceeds, including reasonable
           attorneys' fees and costs allocable to inspecting the Work and the
           plans and specifications therefor), subject to each of the following
           conditions:

                                 (i) If the Work is structural or if the cost of
                      the Work is reasonably estimated to exceed One Hundred
                      Thousand and No/100 Dollars ($100,000.00), the Work shall
                      be conducted under the supervision of a certified and
                      registered architect or engineer reasonably satisfactory
                      to Lender. Before Borrower commences any Work, other than
                      temporary work to protect property or prevent interference
                      with business, Lender shall have approved the plans and
                      specifications for the Work, which approval shall not be
                      unreasonably withheld or delayed, it being nevertheless
                      understood that such plans and specifications shall
                      provide for Work so that, upon completion thereof, the
                      Premises shall be at least equal in value and general
                      utility to the Premises immediately prior to the damage or
                      destruction.

                                 (ii) Each request for payment shall be made on
                      not less than seven Business Days prior notice to Lender
                      and shall be accompanied by a certificate of the architect
                      or engineer in (i) above (or a certificate given by
                      Borrower if no architect or engineer is so required)
                      stating (A) that all of the Work completed has been done
                      in compliance in all material respects with the approved
                      plans and specifications, if required under (i) above, (B)
                      that the sum requested is justly required to reimburse the
                      Borrower for payments by Borrower, or is justly due to the
                      contractor, subcontractors, materialmen, laborers,
                      engineers, architects or other persons rendering services
                      or materials for the Work (giving a brief description of
                      such services and materials), and that when added to all
                      sums previously paid out by Lender does not exceed the
                      value of the Work (including "soft costs") done to the
                      date of such certificate, (C) if the sum requested is to
                      cover payment relating to repair and restoration of
                      Equipment required or relating to the Premises, that title
                      to the items of Equipment covered by the request for
                      payment 


                                       17
<PAGE>   22

                      is vested in Borrower, and (D) that the amount of such
                      Proceeds plus any additional deposit made by Borrower
                      remaining in the hands of Lender will be sufficient on
                      completion of the Work to pay for the same in full (giving
                      in such reasonable detail as Lender may require an
                      estimate of the cost of such completion). Additionally,
                      each request for payment shall contain a statement signed
                      by Borrower approving both the Work done to date and the
                      Work covered by the request for payment in question.

                                 (iii) Each request for payment shall be
                      accompanied by waivers of lien satisfactory to Lender
                      covering that part of the Work for which payment or
                      reimbursement is being requested and, if required by
                      Lender, a search prepared by a title company or licensed
                      abstractor, or by other evidence satisfactory to Lender
                      that there has not been filed with respect to the Premises
                      any mechanics' or other lien or instrument for the
                      retention of title relating to any part of the Work not
                      discharged of record. Additionally, as to any Equipment
                      covered by the request for payment, Lender shall be
                      furnished with evidence of payment therefor and such
                      further evidence satisfactory to assure Lender of its
                      valid first lien on the Equipment.

                                 (iv) Lender shall have the right to inspect the
                      Work at all reasonable times and may condition any
                      disbursement of Proceeds upon the satisfactory completion,
                      as determined in Lender's sole discretion, of any portion
                      of the Work for which payment or reimbursement is being
                      requested. Neither the approval by Lender of the plans and
                      specifications for the Work nor the inspection by Lender
                      of the Work shall make Lender responsible for the
                      preparation of such plans and specifications or the
                      compliance of such plans and specifications, or of the
                      Work, with any applicable law, regulation, ordinance,
                      covenant or agreement.

                                 (v) Proceeds shall not be disbursed more
                      frequently than every thirty (30) days.

                                 (vi) Any request for payment made after the
                      Work has been completed shall be accompanied by a copy or
                      copies of any certificate or certificates required by law
                      to render occupancy and full operation of the Premises
                      legal.

                                 (vii) Upon completion of the Work and payment
                      in full therefor, or upon any failure on the part of
                      Borrower to promptly 


                                       18
<PAGE>   23

                commence the Work or to proceed diligently and
                continuously to completion of the Work, Lender may apply
                any such Proceeds it then or thereafter holds to the
                payment of the Indebtedness; provided, however, that
                Lender, at its sole option, shall be entitled to apply at
                any time all or any portion of insurance Proceeds it then
                holds to the curing of any Event of Default under this
                Deed of Trust, the Note or any other Loan Document.

                      (i) Notwithstanding any other provision of this Section
           2.4, if no Event of Default which permits acceleration shall have
           occurred and be continuing and in Lender's reasonable judgment the
           cost of the Work is less than one percent (1%) of the outstanding
           principal balance of the Note as of the date of loss or damage to the
           Premises and/or Equipment and the Work can be completed in less than
           ninety (90) days, then Lender, upon request by Borrower, shall permit
           Borrower to apply for and receive the insurance Proceeds directly
           from the insurer (and Lender shall advise the insurer to pay over
           such Proceeds directly to Borrower), provided that Borrower shall
           apply such insurance Proceeds solely to the prompt and diligent
           commencement and completion of such Work.

                Section 2.5 Condemnation. Borrower shall notify Lender
immediately of the actual or threatened commencement of any proceedings for the
condemnation or taking of the Premises or any portion thereof and shall deliver
to Lender copies of any and all papers served in connection with such
proceedings. Lender may participate in such proceedings and Borrower shall
deliver to Lender all instruments requested by Lender to permit such
participation. Lender is hereby irrevocably appointed as Borrower's
attorney-in-fact, coupled with an interest, with exclusive power to collect,
receive and retain the Proceeds of any such condemnation and to make any
compromise or settlement in connection with such proceedings, subject to the
provisions of this Deed of Trust. Borrower shall not adjust, compromise, settle
or enter into any agreement with respect to such proceedings without the prior
consent of Lender. All Proceeds of any condemnation, or purchase in lieu
thereof, of the Premises or any portion thereof are hereby assigned to and shall
be paid to Lender. Borrower hereby authorizes Lender to collect and receive such
Proceeds, to give proper receipts and acquittances therefor and, in Lender's
sole discretion, to apply such Proceeds (less any cost to Lender of recovering
and paying out such Proceeds, including reasonable attorneys' fees and costs
allocable to inspecting any repair, restoration or rebuilding work and the plans
and specifications therefor) toward the payment of the Indebtedness or to the
repair, restoration or rebuilding of the Premises in the manner and subject to
the conditions set forth in Section 2.4(h). If the Proceeds are used to reduce
the Indebtedness, they shall be applied in the order provided in Section 2.4(d),
without any prepayment fee. Borrower shall promptly execute and deliver all
instruments requested by Lender for the purpose of confirming the assignment of
the condemnation Proceeds to Lender.

               Section 2.6  Impositions.

                (a) Except to the extent of amounts deposited with Lender for
        the purpose of paying Impositions pursuant to Section 2.7, below,
        Borrower shall pay and discharge all Impositions prior to delinquency
        and shall furnish to Lender validated receipts or other evidence
        satisfactory to Lender showing the payment of such Impositions within
        fifteen (15) days after the same would otherwise have become delinquent.
        Borrower's obligation to pay Impositions pursuant to this Deed of Trust
        shall include, to the extent permitted by applicable law, taxes
        resulting from future changes in law which impose upon Trustee or Lender
        an obligation to pay any property taxes or other Impositions or which
        otherwise adversely affect Trustee's or Lender's interests. Should
        Borrower default in the payment of any Impositions, Lender may (but
        shall not be obligated to) pay such Impositions or any portion thereof
        and Borrower shall reimburse Lender on demand for all such Advances.

                (b) Borrower shall not be required to pay, discharge or remove
        any Imposition so long as Borrower contests in good faith such
        Imposition or the validity, applicability or amount thereof by an
        appropriate legal proceeding which operates to prevent the collection of
        such amounts and the sale of the Mortgaged Property or any portion
        thereof; provided, however, that prior to the date on which such
        Imposition would otherwise have become delinquent Borrower shall have
        (i) given Lender prior notice of such contest and (ii) deposited with
        Lender, and shall deposit such additional amounts as are necessary to
        keep on deposit at all times, an amount equal to at least one hundred
        ten per cent (110%) of the total of (A) the balance of such Imposition
        then remaining unpaid and (B) all interest, penalties, costs and charges
        accrued or accumulated thereon. Any such contest shall be prosecuted
        with due diligence, and Borrower shall promptly pay the amount of such
        Imposition as finally determined, together with all interest and
        penalties payable in connection therewith. Lender shall have full power
        and authority to apply any amount deposited with Lender under this
        Section 2.6(b) to the payment of any unpaid Imposition to prevent the
        sale or forfeiture of the Mortgaged Property for non-payment thereof.
        Lender shall have no liability, however, for failure to so apply any
        amount deposited unless Borrower requests the application of such amount
        to the payment of the particular Imposition for which such amount was
        deposited. Any surplus retained by Lender after payment of the
        Imposition for which a deposit was made shall be repaid to Borrower
        unless an Event of Default shall then exist under the provisions of this
        Deed of Trust, in which case said surplus may be retained by Lender to
        be applied to the Indebtedness. Notwithstanding any provision of this
        Section 2.6(b) to the contrary, Borrower


                                       20
<PAGE>   25



        shall pay any Imposition which it might otherwise be entitled to contest
        if, in the reasonable opinion of Lender, the Mortgaged Property is in
        jeopardy or in danger of being forfeited or foreclosed. If Borrower
        refuses to pay any such Imposition, Lender may (but shall not be
        obligated to) make such payment and Borrower shall reimburse Lender on
        demand for all such Advances. Additionally, in such event, if Lender is
        prevented by law or judicial or administrative order from paying such
        Imposition, then Lender, at its option, may declare the entire
        Indebtedness immediately due and payable.

               Section 2.7 Deposits. Borrower shall deposit with Lender,
monthly, on the due date of each monthly installment under the Note, 1/12th of
the annual charges (as estimated by Lender) for Impositions, and, if required by
Lender, 1/12th of the annual charges for rent (if Borrower is lessee of an
interest in the Mortgaged Property) and insurance premiums with respect to the
Mortgaged Property. If deposits for insurance premiums are required by Lender at
any time when insurance is furnished pursuant to "blanket" policies, the monthly
deposits shall be equal to one twelfth (1/12th) of the product obtained by
multiplying the annual premium for such blanket policy by a fraction, the
numerator of which is the total square footage of the Improvements on the
Mortgaged Property and the denominator is the total square footage of all
improvements covered by such blanket policy. If required by Lender, Borrower
shall also deposit with Lender, simultaneously with such monthly deposits and/or
the execution of this Deed of Trust, a sum of money which together with such
monthly deposits will be sufficient to make the payment of each such charge at
least thirty (30) days prior to the date any Imposition becomes delinquent.
Should such charges not be ascertainable at the time any deposit is required to
be made, the deposit shall be made on the basis of the charges for the prior
year or payment period, as reasonably estimated by Lender. When the charges are
fixed for the then current year or period, Borrower shall deposit any deficiency
on demand. All funds deposited with Lender shall be held without interest
(unless the payment of interest thereon is required under applicable law), may
be commingled with Lender's other funds, and shall be applied by Lender in
payment of the foregoing charges when and as payable provided that no Event of
Default shall exist. Should an Event of Default exist, the funds so deposited
may be applied in payment of the charges for which such funds shall have been
deposited or to the payment of the Indebtedness or any other charges affecting
the Mortgaged Property, as Lender in its sole discretion may determine, but no
such application shall be deemed to have been made by operation of law or
otherwise until actually made by Lender as herein provided. Borrower shall
furnish Lender with bills and all other documents necessary for the payment of
the foregoing charges at least ten (10) days prior to the date on which each
payment thereof shall first become due.

               Section 2.8 Mortgage Taxes. Borrower shall pay any and all taxes,
charges, filing, registration and recording fees, excises and levies imposed
upon Lender by reason of its ownership of, or measured by amounts payable under,
the Note, this Deed of Trust or any other Loan Document (other than income,
franchise and doing business taxes), and shall pay all stamp taxes and other
taxes required to be paid on the Note or the other Loan Documents. If Borrower
fails to make such payment within five days after notice thereof from Lender,
Lender may (but shall not be obligated to) pay the amount due, and Borrower
shall reimburse Lender on demand for all such Advances. If applicable law
prohibits Borrower from paying such taxes, charges, filing, registration and
recording fees, excises, levies, stamp taxes or other taxes, then Lender may
declare the Indebtedness then unpaid to be immediately due and payable. In such
event, no prepayment fee shall be charged.

               Section 2.9  Loan Documents Authorized.

                      (a) The execution and delivery of this Deed of Trust, the
        Note and the other Loan Documents have been duly authorized and there is
        no provision in Borrower's organizational documents, as amended,
        requiring further consent for such action by any other person or entity.

                      (b) Borrower is duly organized, validly existing and in
        good standing under the laws of the state of its formation.

                      (c) Borrower has all necessary franchises, licenses,
        authorizations, registrations, permits and approvals and full power and
        authority to own and operate its properties, including the Mortgaged
        Property, and carry on its business as now conducted in each
        jurisdiction where Borrower conducts its business.

                      (d) The execution and delivery of and performance of its
        obligations under the Loan Documents (i) will not result in Borrower
        being in default under any provision of its organizational documents, as
        amended, any court order, or any mortgage, deed of trust or other
        agreement to which it is a party and (ii) do not require the consent of
        or any filing with any governmental authority, except the recording of
        this Mortgage and the Assignment and filing of UCC-1 financing
        statements.

                      (e) All necessary and required actions have been duly 
        taken by and on behalf of Borrower to make and constitute the Loan
        Documents, and the Loan Documents constitute, legal, valid and binding
        obligations enforceable in accordance with their respective terms,
        subject only to the application of bankruptcy and other laws affecting
        the rights of creditors generally.

                      (f) The Mortgaged Property is in compliance in all
        material respects with all provisions of all zoning, subdivision, land
        use, environmental, traffic, fire, building, and occupational safety and
        health rules, regulations, codes, acts and statutes to which it is
        subject.

               Section 2.10 Maintenance of Existence. So long as it owns the
Mortgaged Property, Borrower shall do all things necessary to preserve and keep
in full force and effect its existence, franchises, licenses, authorizations,
registrations, permits and approvals under the laws of the state of its
formation and the State, and shall comply in all material respects with all
regulations, rules, ordinances, statutes, orders and decrees of any governmental
authority or court now or hereafter applicable to Borrower or to the Mortgaged
Property or any portion thereof.

               Section 2.11 Payment of Liens. Borrower shall pay when due all
payments and charges due under or in connection with any liens and encumbrances
on and security interests in the Mortgaged Property or any portion thereof, all
rents and charges under any ground leases and other leases forming a part of the
Mortgaged Property, and all claims and demands of mechanics, materialmen,
laborers and others which, if unpaid, might result in or permit the creation of
a lien on the Mortgaged Property or any portion thereof, and shall cause the
prompt (but in no event later than thirty (30) days after imposition), full and
unconditional discharge of all liens imposed on or against the Mortgaged
Property or any portion thereof. Notwithstanding the foregoing, Borrower shall
have the right to contest in good faith the validity of any such payment,
charge, rent, claim or demand, and to withhold payment of that portion of the
same which is so contested, so long as Borrower either (a) posts a bond in
compliance with California statutes such that no lien or charge may attach to
the Mortgaged Property in respect of the unpaid amount, or (b) takes such steps
as are approved by Lender in its sole discretion to insure against any
impairment of the security of the Mortgage by reason of such nonpayment.
Borrower shall do or cause to be done, at the sole cost of Borrower, everything
necessary to fully preserve the initial priority of the lien of this Deed of
Trust. If Borrower fails to make any such payment or if a lien attaches to the
Mortgaged Property or any portion thereof, Lender may (but shall not be
obligated to) make such payment or discharge such lien and Borrower shall
reimburse Lender on demand for all such Advances.

               Section 2.12 Costs of Defending and Upholding the Lien.
Lender and, to the extent authorized by Lender, Trustee may, after notice to
Borrower, (a) appear in and defend any action or proceeding, in the name and on
behalf of either Lender or Borrower, in which Trustee or Lender is named or
which Lender in its sole discretion determines may adversely affect the
Mortgaged Property, this Deed of Trust, the lien hereof or any other Loan
Document; and (b) institute any action or proceeding which Lender in its sole
discretion determines should be instituted to protect the interest or 


                                       23
<PAGE>   28

rights of Lender or Trustee's interest in the Mortgaged Property or under this
Deed of Trust or any other Loan Document, including, without limitation,
foreclosure proceedings. Borrower agrees to bear and shall pay or reimburse
Trustee and Lender on demand for all Advances and expenses (including reasonable
attorneys' fees) relating to or incurred by Lender in connection with any such
action or proceeding.

               Section 2.13 Costs of Enforcement. Borrower agrees to bear and
shall pay or reimburse Trustee and Lender on demand for all Advances and
expenses (including reasonable attorneys' and appraisers' fees and the expenses
and reasonable fees of any receiver or similar official) of or incidental to the
collection of the Indebtedness, any foreclosure of this Deed of Trust or any
other Loan Document, any enforcement, compromise or settlement of this Deed of
Trust, any other Loan Document or the Indebtedness, or any defense or assertion
of the rights or claims of Trustee or Lender in respect of any thereof, by
litigation or otherwise.

               Section 2.14 Interest on Advances and Expenses. All Advances made
and any reasonable expenses incurred at any time by Trustee or Lender pursuant
to the provisions of this Deed of Trust or the other Loan Documents or under
applicable law shall be secured by this Deed of Trust as part of the
Indebtedness, with equal rank and priority. All such Advances and expenses shall
bear interest at the Default Rate from the date that each such Advance or
expense is made or incurred to the date of repayment and all such Advances and
expenses with interest thereon shall be payable to Lender on demand.

               Section 2.15 Indemnification. Borrower shall indemnify and hold
Trustee and Lender and their respective directors, officers, employees and
agents harmless from and against and reimburse them for all Losses which may be
imposed upon, asserted against, or incurred or paid by any of them (a) by reason
of, on account of or in connection with any act or occurrence relating to the
Mortgaged Property or any bodily injury, death, other personal injury or
property damage occurring in, upon or in the vicinity of the Premises from any
cause whatsoever, (b) as a result of the failure of Borrower to perform any of
its obligations under any of the Loan Documents, or (c) on account of any
transaction otherwise arising out of or in any way connected with the Mortgaged
Property, this Deed of Trust or the Indebtedness, except Borrower shall have no
indemnification obligation for losses caused by any indemnified person's gross
negligence or willful misconduct.

               Section 2.16 Financial Statements; Records. Borrower shall keep
adequate books and records of account in accordance with generally accepted
accounting principles ("GAAP"), or in accordance with other methods acceptable
to Lender in its sole discretion, consistently applied, and shall furnish to

                requirements of paragraph 2.16(a) above) as may, from time to
                time, be reasonably required by Lender and in form and substance
                reasonably satisfactory to Lender; and

                             (iv) Borrower's books and records regarding the

               Borrower's books and records of account.

                      (d) Borrower's agreements as set forth in this Section
        2.16 constitute material inducements to Lender in making the loan
        secured by this Deed of Trust. Accordingly, in the event Borrower fails
        to furnish any financial report or tax return required by this section
        as and when required, time being of the essence, then, in addition to
        all other remedies available to Lender under this Deed of Trust,
        Borrower agrees to pay Lender within ten (10) days following demand
        therefor, a late charge of Five Hundred and No/100 Dollars ($500) for
        each day or part thereof that any such financial report or tax return
        shall be overdue. In addition, Borrower hereby appoints Lender its
        attorney in fact for the purpose of hiring at Borrower's cost an
        auditing firm to prepare and deliver to Lender any overdue rent roll,
        operating statement, balance sheet income statement or other financial
        report required hereunder in the event Borrower fails or refuses to
        furnish to Lender those financial reports as and when due. The foregoing
        late charges and the costs and expenses of the auditor shall be due and
        payable to Lender within ten (10) days following demand and shall
        constitute a part of the Indebtedness.

               Section 2.17 Prohibition Against Conveyances and Encumbrances.
Except with the prior consent of Lender, Borrower shall not and shall not permit
others to convey, assign, sell, mortgage, encumber, pledge, hypothecate, grant a
security interest in, grant purchase options with respect to, or otherwise
dispose of
 (directly or indirectly, voluntarily or involuntarily, by operation of law or
otherwise, and whether or not for consideration or of record) all or any portion
of any legal or beneficial interest (a) in all or any portion of the Mortgaged
Property including the Leases; (b) in the stock of any corporation which is
either Borrower or a beneficial owner of all or any portion of Borrower or of
the Mortgaged Property; (c) in Borrower (or any trust of which Borrower is a
trustee); or (d) if Borrower is a limited or general partnership, limited
liability company, joint venture, trust, nominee trust, tenancy in common or
other unincorporated form of business association or form of ownership, in any
person, firm or entity having a direct or indirect legal or beneficial ownership
interest in Borrower, including any legal or beneficial interest in any general
partner of Borrower, in any general partner of any general partner of Borrower
or in any member 


                                       27
<PAGE>   32

of a limited liability company. The foregoing shall not prohibit transfers of
limited partnership interests in Borrower's managing member or transfers of the
stock of Arden Realty, Inc. or transfers subject to Sections 6.13 or 6.15 or
Borrower's leases of the Premises. Any such transfer or encumbrance to which
Lender consents must be to a United States citizen or an entity owned or
controlled by United States citizens. All requests for Lender's consent under
this Section 2.17 shall be on a form previously approved by Lender and shall be
accompanied by the payment of Lender's standard processing fee for such
transactions then in effect. Lender's consent to any of the foregoing actions,
if given (in Lender's sole discretion), may be conditioned upon an increase in
the interest rate, a change in maturity date, amortization period or other terms
under the Note, the payment of a transfer fee and/or any other requirements of
Lender. In addition to the standard processing fee and the transfer fee referred
to in this Section 2.17, Borrower agrees to bear and shall pay or reimburse
Lender on demand for all reasonable expenses (including reasonable attorneys'
fees, title search costs, and title insurance endorsement premiums) incurred by
Lender in connection with the review, approval and documentation of any such
transaction.

               Section 2.18 Estoppel Certificates. Within ten (10) Business Days
of a request by Lender, Borrower shall furnish to Lender a duly acknowledged
written statement confirming the amount of the outstanding Indebtedness, the
terms of payment and maturity date of the Note, the date to which interest has
been paid, and whether any offsets or defenses exist against the Indebtedness.
If any such offsets or defenses are alleged to exist, the nature thereof shall
be set forth in detail. Borrower shall also deliver to such tenants of the
Premises as Lender may designate by written notice to Borrower, and exercise its
reasonable best efforts to cause such tenants to furnish to Lender, within 30
days of its request therefor, tenant estoppel letters; provided that Lender
shall not request an estoppel certificate from any one tenant more often than
once in a calendar year period.

               Section 2.19  Assignment of Leases and Property Income.

                      (a) Borrower hereby absolutely and unconditionally assigns
        and transfers to Lender the Leases and the Property Income. Borrower
        shall not otherwise assign, transfer or encumber in any manner the
        Leases or the Property Income or any portion thereof. Borrower shall
        have a license, revocable by Lender, to collect and use the Property
        Income as the same becomes due and payable so long as no Event of
        Default which permits acceleration of the Loan has occurred and is
        continuing, but may not collect any Property Income more than thirty
        (30) days in advance of the date the same becomes due (other than
        customary security deposits). The assignment in this Section 2.19 shall
        constitute an absolute and present assignment of the Leases and the
        Property Income, and 



                                       28
<PAGE>   34

        not an additional assignment for security, and the existence or exercise
        of the Borrower's revocable license to collect Property Income shall not
        operate to subordinate this assignment to any subsequent assignment. The
        exercise by Lender of any of its rights or remedies under this Section
        2.19 shall not be deemed or construed to make Lender a
        mortgagee-in-possession.

                      (b) Borrower shall furnish Lender with executed copies of
        all Leases, and renewals or material modifications of Leases, as
        follows: (i) if the Lease is not or was not subject to Lender's approval
        pursuant to Section 2.19(d) (i.e., the Lease complies with the
        conditions described in clauses (i), (ii) and (iii) of Section 2.19(d)),
        such copies shall be furnished to Lender on or before the date that the
        next quarterly rent roll is required to be delivered to Lender pursuant
        to Section 2.16(a); and (ii) if the Lease is or was subject to Lender's
        approval pursuant to Section 2.19(d), such copies shall be furnished to
        Lender within ten (10) days after execution of such Lease, renewal or
        material modification. No material changes may be made to the
        Lender-approved standard lease form without the prior written consent of
        Lender.

                      (c) Borrower shall perform all obligations as lessor under
        all Leases and shall enforce all of the terms, covenants and conditions
        contained in upon the part of the lessee thereunder to be performed or
        observed, short of termination thereof. Additionally, Borrower shall not
        take any action which would cause any Lease to cease to be in full force
        and effect. Except with the prior consent of Lender, Borrower shall not
        (i) cancel, terminate (with the exception of terminations of Leases the
        execution of which did not require Lender's prior written consent
        pursuant to Section 2.19(d), below, wherein the tenant is in material
        default and such termination is carried out in the manner of a prudent
        landlord in the ordinary course of business) or surrender any Lease or
        consent to any cancellation, termination, surrender, subletting or
        assignment (with the exception of consent to subletting or assignment of
        any Lease the execution of which did not require Lender's prior written
        consent pursuant to Section 2.19(d) below) thereof; (ii) subordinate any
        Lease to any mortgage, deed of trust or other security interest that is
        subordinate to this Deed of Trust; (iii) enter into any new Lease
        (except as permitted in Section 2.19(d) below); (iv) waive any default
        under or breach of any Lease; (v) consent to or accept any prepayment or
        discount of rent or advance rent under any Lease; (vi) take any other
        action in connection with any Lease which would impair or jeopardize the
        validity of such Lease or the Lender's interest therein; or (vii) alter,
        modify or change the terms of any guaranty, letter of credit or other

                      (d) Except as hereinafter provided, Lender's prior written
        consent shall be required for entering into any new Lease, or agreeing
        to extend or modify any existing Lease, and all Leases shall be written
        on the standard form of lease approved in writing by Lender without
        material modification to such form. Notwithstanding the foregoing,
        Lender's prior written consent shall not be required for entering into
        new Leases, extensions or modifications of Leases, provided that (i) the
        Lease is the result of an arm's-length transaction, and provides for the

        nor the activity of the tenant will violate any provision of any other
        Lease or restriction or covenant affecting the Premises or this Deed of
        Trust or any other Loan Document, including Section 2.20(b) hereof; and
        (iii) the Lease meets either of the following criteria:

                                    (A) (1) such Lease is a non-residential
                      Lease covering five thousand (5,000) square feet of net
                      rentable area or less, or a residential Lease relating to
                      a residential multifamily property, or an extension or
                      modification thereof; and (2) the Lease term is no greater
                      than five (5) years with no options to extend the term;
                      and (3) the Lease contains no purchase options, no rights
                      of first refusal, no rights to lease other space, and no
                      expansion rights; or

                                    (B) (1) such Lease is a non-residential
                      Lease covering more than five thousand (5,000) but less
                      than ten thousand one (10,001) square feet of net rentable
                      area, or an extension or renewal thereof; and (2) the
                      Lease utilized is on a standard form previously approved
                      by Lender, without material modification.

If a prospective Lease or extension or modification of a Lease does not meet the
above detailed conditions and if approval of a Lease, extension or modification
is requested by Borrower, Lender shall review the prospective Lease, extension
or modification as follows: Borrower shall submit to Lender: (1) a copy of the
prospective lease highlighted to show difference from the approved standard
lease form; (2) a lease summary letter in substantially the form approved by
Lender; (3) financial and operational information regarding the prospective
tenant including a description of the tenant's business, industry, operations
and owners and the tenant's last two (2) years' cash flow and income statements
and balance sheet and a credit report for the tenant, to the extent that such
information has been obtained by Borrower. Lender shall have ten (10) Business
Days from the date of its actual receipt of all such information to provide its
approval or rejection of the prospective lease to Borrower. If Lender fails to
respond within said ten (10) Business Day period, Borrower shall again submit
such information together with a cover letter advising Lender that failure to
respond within a five (5) 


                                       30

Business Day period shall result in such Lease being deemed approved. In the
event that Lender does in fact fail to approve or disapprove the Lease in
writing within five (5) Business Days after receipt of the second request for
approval, such lease will be deemed approved. All of the foregoing submissions
shall be sent to Lender by either certified or registered mail, return receipt
requested, or by recognized, national overnight courier service, with proof of
receipt.

                      (e) In addition to the foregoing, Borrower shall comply
        with all terms and provisions of the Assignment.

        2.20 or of any other provision thereof including, without limitation,
        (i) all actual and consequential damages, (ii) the costs of any required
        Remediation, and (iii) the costs of the preparation and implementation

               Section 2.21  Environmental Matters; Remedial Work.

                      (a) If any investigation, site monitoring, containment,
        cleanup, removal, restoration or other Remediation of any kind or nature
        (collectively, the "REMEDIAL WORK") is required under any applicable
        Environmental Law because of or in connection with the current or future
        presence, suspected presence, release or suspected release of a
        Hazardous Substance into the air, soil, ground water, surface water, or
        soil vapor on, under or about the Premises or any portion thereof,
        Borrower shall promptly commence and diligently prosecute to completion
        all such Remedial Work. In all events, such Remedial Work shall be
        commenced 



                                       33
<PAGE>   39

        within 45 days after any demand therefor by Lender or such shorter
        period as may be required under any applicable Environmental Law.

                      (b) All Remedial Work shall be performed by contractors,
        and under the supervision of a consulting engineer, each approved in
        advance by Lender. All costs and expenses of such Remedial Work and
        Lender's monitoring or review of such Remedial Work (including
        reasonable attorneys' fees) shall be paid by Borrower. If Borrower does
        not timely commence and diligently prosecute to completion the Remedial
        Work, Lender may (but shall not be obligated to) cause such Remedial
        Work to be performed. Borrower agrees to bear and shall pay or reimburse
        Lender on demand for all Advances and expenses (including reasonable
        attorneys' fees) relating to or incurred by Lender in connection with
        monitoring, reviewing, or if Borrower fails to perform, performing any
        Remedial Work required hereunder.

                      (c) Except with Lender's prior consent, Borrower shall not
        commence any Remedial Work or enter into any settlement agreement,
        consent decree or other compromise relating to any Hazardous Substances
        or Environmental Laws which might, in Lender's sole judgment, impair the
        value of Lender's security hereunder. Lender's prior consent shall not
        be required, however, if the presence or threatened presence of
        Hazardous Substances on, under or about the Premises poses an immediate
        threat to the health, safety or welfare of any person or is of such a
        nature that an immediate remedial response is necessary, and it is not
        possible to obtain Lender's prior consent, or if Remedial Work is
        required under Environmental Laws. In such event Borrower shall notify
        Lender as soon as practicable of any action taken.

               Section 2.22  Environmental Matters; Inspection.

                      (a) Lender shall have the right at all reasonable times 
        upon reasonable prior notice to enter upon and inspect all or any
        portion of the Premises, provided that such inspections shall not
        unreasonably interfere with the operations of the tenants of the
        Premises. Lender may select a consulting engineer to conduct and prepare
        reports of such inspections. The inspection rights granted to Lender in
        this Section 2.22 shall be in addition to, and not in limitation of, any
        other inspection rights granted to Lender in this Deed of Trust, and
        shall expressly include the right to conduct soil borings and other
        customary environmental tests, assessments and audits.

                      (b) Borrower agrees to bear and shall pay or reimburse
        Lender on demand for all Advances and expenses (including reasonable
        attorneys' fees)

relating to or incurred by Lender in connection with
        the inspections and reports described in this Section 2.22 in the
        following situations:

                             (i) If Lender has reasonable grounds to believe, at
               the time any such inspection is ordered, that there exists an
               Environmental Violation or that a Hazardous Substance is present
               on, under or about the Premises or is migrating to or from
               adjoining property, except under conditions permitted by
               applicable Environmental Laws and not prohibited by any Loan
               Document;

                             (ii) if any such inspection reveals an
               Environmental Violation or that a Hazardous Substance is present
               on, under or about the Premises or is migrating to or from
               adjoining property, except under conditions permitted by
               applicable Environmental Laws and not prohibited by any Loan
               Document; or

                             (iii) if an Event of Default exists at the time any
               such inspection is ordered.

               Section 2.23 Management. At all times prior to the payment in
full of the Indebtedness, the Mortgaged Property shall be managed by a
management company reasonably satisfactory to Lender, and pursuant to a
management agreement reasonably satisfactory to Lender. Such management
agreement, and any leasing commissions agreement affecting the Mortgaged
Property, shall be subordinate to this Deed of Trust. Any time the management is
not reasonably satisfactory to Lender, Borrower shall have a reasonable
opportunity, not to exceed ninety (90) days, to obtain approved and satisfactory
management prior to Lender accelerating the Loan. Any leasing commissions and
management agreement affecting the security for this Loan must be subordinate to
the lien of the Loan Documents. As of the date hereof, Lender approves Arden
Realty, Inc., a Maryland corporation, or an entity controlled by or under common
control with Arden Realty, Inc., as manager of the Mortgaged Property, reserving
the right, however, to revoke such approval: (i) upon the occurrence of an Event
of Default which permits acceleration, and/or (ii) upon a reasonable
determination by Lender that any material portion of the Mortgaged Property is
not being properly managed.

               Section 2.24 ERISA. As of the date hereof and throughout the term
of this Deed of Trust, (i) Borrower is not and will not be an "employee benefit
plan" as defined in Section 3(3) of ERISA, which is subject to Title I of ERISA;
(ii) the assets of Borrower do not and will not constitute "plan assets" of one
or more such plans for purposes of Title I of ERISA; (iii) Borrower is not and
will not be a "governmental plan" within the meaning of Section 3(3) of ERISA;
(iv) transactions by or with 


                                       35
<PAGE>   41

Borrower are not and will not be subject to state statutes applicable to
Borrower regulating investments of fiduciaries with respect to governmental
plans; and (v) Borrower shall not engage in any transaction which would cause
any obligation, or action taken or to be taken, hereunder (or the exercise by
Lender of any of its rights under this Deed of Trust, the Note, or the other
Loan Documents) to be a non-exempt (under a statutory or administrative class
exemption) prohibited transaction under ERISA. Borrower further agrees to
deliver to Lender such certifications or other evidence of compliance with the
provisions of this Section 2.24 as Lender may from time to time request.

               Section 2.25 Litigation. Borrower shall give prompt written
notice to Lender of any litigation or governmental proceedings pending or
threatened against Borrower which is reasonably likely to have a Material
Adverse Effect.

               Section 2.26 Notice of Default. Borrower shall promptly advise

otherwise, or of the occurrence of any Default or Event of Default.

               Section 2.27 Single Purpose Entity. Borrower shall at all times
be a Single-Purpose Entity.

               Section 2.28 Trade Indebtedness. Borrower will pay its trade
payables within thirty (30) days of the date due, unless Borrower is in good
faith contesting Borrower's obligation to pay such trade payable in a manner
satisfactory to Lender (which may include Lender's requirement that Borrower
post security with respect to the contested trade payable).

               Section 2.29 Conduct of Business. Borrower shall cause the 
operation of the Mortgaged Property to be conducted at all times in a manner
consistent with the following:

                      (a) to maintain or cause to be maintained the standard of
        operations at the Mortgaged Property at all times at a level necessary
        to insure a level of quality for the Mortgaged Property consistent with
        similar facilities in the same competitive market;

                      (b) to operate or cause to be operated the Mortgaged
        Property in a prudent manner in compliance in all material respects with
        applicable Legal Requirements and the insurance requirements of this
        Deed of Trust relating thereto and cause all licenses, permits, and any
        other agreements necessary for the continued use and operation of the
        Mortgaged Property to remain in effect; and

                      (b) Borrower, immediately upon the execution and delivery
        of this Deed of Trust, and thereafter from time to time at the request
        of Lender, shall cause this Deed of Trust, any security agreement,
        mortgage, modification or amendment supplemental hereto and each
        document, instrument and agreement of further assurance, to be filed,
        registered or recorded or refiled, re-registered or re-recorded in such
        manner and in such places as may be required by any present or future
        law in order to publish notice of and perfect the lien or estate of this
        Deed of Trust upon the Mortgaged Property and to accomplish the purposes
        of this Deed of Trust.

                      (c) Borrower shall pay all intangible taxes, recording 
        taxes, filing, registration and recording fees, all refiling, all

        subsequent to the date hereof, in any manner changing or modifying the
        laws now in force governing the taxation of mortgages or security
        agreements or debts secured thereby or the manner of collecting such
        taxes so as to adversely affect Lender (other than taxes on Lender's
        income), this Deed of Trust or the lien hereof, Borrower will pay any
        such tax on or before the due date thereof. If Borrower fails to make
        such prompt payment or if, in the reasonable opinion of Lender, any such
        state, federal, municipal, or other governmental law, order, rule or
        regulation prohibits Borrower from making such payment or would penalize
        Lender if Borrower makes such

        payment or if, in the opinion of Lender, the making of such payment
        might result in the imposition of interest beyond the maximum amount
        permitted by any applicable law, then the entire balance of the Loan,
        accrued interest thereon and all other obligations in connection with
        the Loan shall, at the option of Lender, become due and payable (without
        prepayment premium) on the date that is one hundred twenty (120) days
        after written notice to Borrower of any of the foregoing.

                      (e) Borrower hereby indemnifies and holds harmless Lender
        from any sales or use tax that may be imposed on Lender by virtue of the
        Loan from Lender to Borrower other than taxes imposed on the income,
        stock or assets of Lender.

                      (f) Borrower shall, upon Lender's request therefor given
        from time to time after the occurrence and during the continuance of any
        Event of Default which permits acceleration of the Loan, pay for (a)
        reports of UCC, federal tax lien, state tax lien, judgment and pending
        litigation searches with respect to Borrower and (b) searches of title
        to the Mortgaged Property, each such search to be conducted by search
        firms reasonably designated by Lender in each of the locations
        reasonably designated by Lender.

                      (g) Borrower shall furnish to Lender all instruments,
        documents, boundary surveys, footing or foundation surveys,
        certificates, plans and specifications, appraisals, title and other
        insurance reports and agreements, and each and every other document,
        certificate, agreement and instrument required to be furnished pursuant
        to the terms of the Loan Documents; and

                      (h) Borrower shall do and execute all and such further 
        lawful acts, conveyances and assurances for the better and more
        effective carrying out of the intents and purposes of this Deed of Trust
        and the Loan Documents, as Lender shall reasonably require from time to
        time in Lender's discretion.

               Section 2.31 No Joint Assessment; Separate Lots. Borrower has not
and shall not suffer, permit or initiate the joint assessment of the Mortgaged
Property (i) with any other real property constituting a separate tax lot, and
(ii) with any portion of the Mortgaged Property which may be deemed to
constitute personal property, or any other procedure whereby the lien of any
taxes which may be levied against such personal property shall be assessed or
levied or charged to the Mortgaged Property as a single lien. The Mortgaged
Property is comprised of one or more parcels, each of which constitutes a
separate tax lot and none of which constitutes a portion of any other tax lot.

                               SECURITY AGREEMENT


               Section 3.1 Warranties, Representations and Covenants of
Borrower. Borrower covenants, warrants, represents and agrees with and to
Trustee and Lender as follows:

                    (a) This Deed of Trust constitutes a security agreement
          under the Code and serves as a fixture filing in accordance with the
          Code. This Deed of Trust creates a security interest in favor of
          Lender as secured party under the Code with respect to all property
          (specifically including the Collateral) included in the Mortgaged
          Property which is covered by the Code. The mention of any portion of
          the Mortgaged Property in a financing statement filed in the records
          normally pertaining to personal property shall not derogate from or
          impair in any manner the intention of Borrower and Lender hereby
          declared that all items of collateral described in this Deed of Trust
          are part of the real property encumbered hereby to the fullest extent
          permitted by law, regardless of whether any such item is physically
          attached to the Improvements or whether serial numbers are used for
          the better identification of certain items. Specifically, the mention
          in any such financing statement of (i) the rights in or the Proceeds
          of any policy of insurance, (ii) any condemnation Proceeds, (iii)
          Borrower's interest in any Leases or Property Income, or (iv) any
          other item included in the Mortgaged Property, shall not be construed
          to alter, impair or impugn any rights of Lender as determined by this
          Deed of Trust or the priority of Lender's lien upon and security
          interest in the Mortgaged Property. Any such mention shall be for the
          protection of Lender in the event that notice of Lender's priority of
          interest as to any portion of the Mortgaged Property is required to be
          filed in accordance with the Code to be effective against or take
          priority over the interest of any particular class of persons,
          including the federal government or any subdivision or instrumentality
          thereof.

                    (b) Except for the security interest granted by this Deed of
          Trust, Borrower is and, as to portions of the Collateral to be
          acquired after the date hereof, will be the sole owner of the
          Collateral, free from any lien, security interest, encumbrance or
          adverse claim thereon of any kind whatsoever except Permitted
          Encumbrances. Borrower shall notify Lender of, and shall defend the
          Collateral against, all claims and demands of all persons at any time
          claiming the same or any interest therein.

                    (c) Except as otherwise provided in this Deed of Trust,
          Borrower shall not lease, sell, convey or in any manner transfer the
          Collateral without the prior consent of Lender.


                                       39
<PAGE>   45

                      (d) The Collateral is not used or bought for personal,
        family or household purposes.

                      (e) The Collateral shall be kept on or at the Premises,
        and Borrower shall not remove the Collateral from the Premises without
        the prior consent of Lender, except such portions or items of the
        Collateral as are consumed or worn out in ordinary usage, all of which
        shall be promptly replaced by Borrower with items of equal or greater
        value, and Borrower's books and records shall be maintained by Borrower,
        or by the manager appointed pursuant to a management agreement permitted
        pursuant to Section 2.23, either at Borrower's principal place of
        business or at such manager's place of business (so long as such places
        of business shall be located in Southern California) or at another
        location in Southern California reasonably approved by Lender.

        (f) In the event of any change in name, identity or structure of
        Borrower, Borrower shall notify Lender thereof and promptly after
        request shall execute, file and record such Code forms as are necessary
        to maintain the priority of Lender's lien upon and security interest in
        the Collateral, and shall pay all expenses and fees in connection with
        the filing and recording thereof. If Lender shall require the filing or
        recording of additional Code forms or continuation statements, Borrower
        shall, promptly after request, execute, file and record such Code forms
        or continuation statements as Lender shall deem necessary (subject to
        Lender's right to sign such statements on behalf of Borrower as provided
        in Subsection 3.01(g)), and shall pay all expenses and fees in
        connection with the filing and recording thereof. If Lender shall
        initially pay such expenses, Borrower shall promptly reimburse Lender
        for the expenses.

                      (g) Borrower hereby irrevocably appoints Lender as its
        attorney-in-fact, coupled with an interest, to execute in the name of
        and on behalf of Borrower any and all financing statements and
        continuations thereof and to file with the appropriate public office on
        its behalf and at its expense any financing or other statements signed
        only by Lender, as secured party, in connection with the Collateral
        covered by this Deed of Trust.

               Section 3.2 Financing Statements. A CARBON, PHOTOGRAPHIC OR OTHER
REPRODUCTION OF THIS DEED OF TRUST OR ANY FINANCING STATEMENT RELATING TO THIS
DEED OF TRUST SHALL BE SUFFICIENT AS A FINANCING STATEMENT.

               Section 3.3 Addresses. The mailing address of Borrower and the
address of Lender from which information concerning the security interest
granted hereby may be obtained are set forth on the Cover Sheet of this Deed of
Trust. Borrower 


                                       40
<PAGE>   46

maintains its sole place of business or its chief executive
office at the address shown on said Cover Sheet, and Borrower shall immediately
notify Lender in writing of any change in said place of business or chief
executive office.

                                   ARTICLE IV.

        any other Loan Document which permits acceleration of the Loan;

                      (d) if any representation made herein or in any other Loan

                      (h) if Borrower, any general partner of Borrower or any

        liability company) or any guarantor of the Note consents to the filing
        of, or commences or consents to the commencement of, any Bankruptcy
        Proceeding with respect to Borrower or such guarantor;

                      (i) if any Bankruptcy Proceeding shall have been filed
        against Borrower, any general partner of Borrower, any managing or

       terminated within 90 days of such filing;

                      (j) if Borrower, any general partner of Borrower, any

       liability company) or any guarantor of the Note is adjudicated bankrupt
       or insolvent or a petition for reorganization of Borrower or any such

       encumbering all or any portion of the Mortgaged Property which is
       subordinate or superior to the lien of this Deed of Trust or if any
       party under any such instrument shall commence a foreclosure or other
       collection or enforcement action in connection therewith, provided,
       however, that this provision shall not be deemed to be a waiver of the
       provisions of Section 2.17 prohibiting further encumbrances or of any
       other provision of this Deed of Trust, it being understood that it is an
       event of default under this Deed of Trust to permit any further

       portion of the Mortgaged Property without the prior written consent of
       the Lender;

                     (o) except as permitted in this Deed of Trust, the actual

<PAGE>   48

                    (p) damage to any of the Mortgaged Property in any manner
          which is not covered by insurance as a result of Borrower's failure to
          maintain insurance required in accordance with this Deed of Trust.

               Section 4.2 Remedies. Upon the occurrence and during the
continuance of any Event of Default which permits acceleration of the Loan,
Lender may take such actions against Borrower and/or the Mortgaged Property or
any portion thereof as it deems advisable to protect and enforce its rights
against Borrower and in and to the Mortgaged Property, without notice or demand
except as set forth below. Any such actions taken by Lender shall be cumulative
and concurrent and may be pursued independently, singly, successively, together
or otherwise, at such time and in such order as Lender may determine in its sole
discretion, to the fullest extent permitted by law, without impairing or
otherwise affecting the other rights and remedies of Lender permitted by law,
equity or contract or as set forth herein or in the other Loan Documents. Such
actions may include the following:

                    (a) Subject to any applicable provisions of the Note, Lender
          may declare the entire principal balance under the Note then unpaid,
          together with all accrued and unpaid interest thereon, and all other
          unpaid Indebtedness, to be immediately due and payable.

                    (b) Lender may enter into or upon the Mortgaged Property,
          personally or by its agents, nominees or attorneys, and may dispossess
          Borrower and its agents and servants therefrom, and thereupon Lender
          at its sole discretion may: (i) use, operate, manage, control, insure,
          maintain, repair, restore and otherwise deal with all and every
          portion of the Mortgaged Property and conduct business thereon, in any
          case either in the name of Lender or in such other name as Lender
          shall deem best; (ii) complete any construction on the Mortgaged
          Property in such manner and form as Lender deems advisable; (iii) make
          alterations, additions, renewals, replacements and improvements to or
          on the Mortgaged Property; (iv) exercise all rights and powers of
          Borrower with respect to the Mortgaged Property, whether in the name
          of Borrower or otherwise, including the right to make, cancel, enforce
          or modify Leases, obtain and evict tenants, and demand, sue for,
          collect and receive all Property Income; and (v) apply the receipts of
          Property Income to the payment of the Indebtedness (including any
          prepayment fee payable under the Note) in such order as Lender shall
          determine in its sole discretion, after deducting therefrom all
          expenses (including reasonable attorneys' fees) incurred in connection
          with the aforesaid operations and all amounts necessary to pay the
          Impositions, insurance and other charges in connection with the
          Mortgaged Property, as well as just and reasonable compensation for
          the services of Lender, its agents, nominees and attorneys.

                    (c) Subject to any applicable provisions of the Note, with
          or without entry, personally or by its agents, nominees or attorneys,
          Lender may require Trustee to sell all or any portion of the Mortgaged
          Property and all or any portion of Borrower's estate, right, title,
          interest, claim and demand therein and right of redemption thereof at
          one or more private or public sales in the manner and to the extent
          permitted by law, as an entirety or in parcels or portions, and
          Trustee shall have any statutory power of sale as may be provided by
          law in the State.

                    (d) Subject to any applicable provisions of the Note, Lender
          may institute proceedings for the complete foreclosure of this Deed of
          Trust by power of sale or by judicial action, in which case the
          Mortgaged Property may be sold for cash or upon credit, as an entirety
          or in parcels or portions. Lender shall have the right to foreclose
          this Deed of Trust, by exercise of the power of sale or by judicial
          action, either (a) in a single foreclosure with respect to all of the
          Mortgaged Property, or (b) in separate, serial foreclosures with
          respect to one or more properties included within the Mortgaged
          Property. If Lender forecloses this Deed of Trust with respect to less
          than all of the Mortgaged Property, this Deed of Trust shall not
          terminate upon such foreclosure, but shall remain in effect with
          respect to the remainder of the Mortgaged Property.

                    (e) [Deleted]

                    (f) Lender may institute, or require Trustee to institute,
          an action, suit or proceeding at law or in equity for the specific
          performance of any covenant, condition or agreement contained herein
          or in the Note or any other Loan Document, or in aid of the execution
          of any power granted hereunder or for the enforcement of any other
          appropriate legal or equitable remedy.

                    (g) Lender and Trustee shall have the rights and may take
          such actions as are set forth, described or referred to in any rider
          entitled "Rider - Applicable State Law Provisions" attached hereto and
          made a part hereof, or as are permitted by the laws of the State.

                    (h) Subject to any applicable provisions of the Note, Lender
          may recover judgment on the Note, either before, during or after any
          proceedings for the foreclosure or enforcement of this Deed of Trust.

                    (i) Lender may secure the appointment of a receiver,
          trustee, liquidator or similar official of the Mortgaged Property or
          any portion thereof, and Borrower hereby consents and agrees to such
          appointment, without notice to Borrower and without regard to the
          adequacy of the security for the Indebtedness and without regard to
          the solvency of Borrower or any other person, firm or entity 


                                       44
<PAGE>   50

          liable for the payment of the Indebtedness, and such receiver or other
          official shall have all rights and powers permitted by applicable law
          and such other rights and powers as the court making such appointment
          may confer, but the appointment of such receiver or other official
          shall not impair or in any manner prejudice the rights of Lender to
          receive the Property Income pursuant to this Deed of Trust or the
          Assignment.

                    (j) Lender may exercise any or all of the remedies available
          to a secured party under the Code, but any sale of the Equipment shall
          be subject to any applicable provisions of the Note.

                    (k) Lender may pursue, or require Trustee to pursue, any
          other rights and remedies of Lender permitted by law, equity or
          contract or as set forth herein or in the other Loan Documents.

                    (l) Lender may apply any funds then on deposit with Lender
          for payment of Impositions, ground rent or insurance premiums in the
          manner provided for in Section 2.7.

                    (m) Lender in its sole discretion may surrender any
          insurance policies and collect the unearned premiums and apply such
          sums against the Indebtedness.

               Section 4.3   General Provisions Regarding Remedies.

                    (a) Effect of Judgment. No recovery of any judgment by
          Lender or Trustee and no levy of an execution under any judgment upon
          the Mortgaged Property or upon any other property of Borrower shall
          affect in any manner or to any extent the lien of this Deed of Trust
          upon the Mortgaged Property or any portion thereof, or any rights,
          powers or remedies of Lender or Trustee hereunder. Such lien, rights,
          powers and remedies of Lender and Trustee shall continue unimpaired as
          before.

                    (b) Continuing Power of Sale. The power of sale conferred
          upon Lender in this Deed of Trust shall not be exhausted by any one or
          more sales as to any portion of the Mortgaged Property remaining
          unsold, but shall continue unimpaired until all of the Mortgaged
          Property is sold or all of the Indebtedness is paid.

                    (c) Right to Purchase. At any sale of the Mortgaged Property
          or any portion thereof pursuant to the provisions of this Deed of
          Trust, Lender or Trustee shall have the right to purchase the
          Mortgaged Property being sold, and in such 


                                       45
<PAGE>   51

          case shall have the right to credit against the amount of the bid made
          therefor (to the extent necessary) all or any portion of the
          Indebtedness then due.

                    (d) Right to Terminate Proceedings. Lender or Trustee may
          terminate or rescind any proceeding or other action brought in
          connection with its exercise of the remedies provided in Section 4.2
          at any time before the conclusion thereof, as determined in Lender's
          sole discretion and without prejudice to Lender.

                    (e) No Waiver or Release. Lender may resort, or require
          Trustee to resort, to any remedies and the security given by the Loan
          Documents, in whole or in part, and in such portions and in such order
          as determined in Lender's sole discretion. No such action shall in any
          way be considered a waiver of any rights, benefits or remedies
          evidenced or provided by the Loan Documents. The failure of Lender or
          Trustee to exercise any right, remedy or option provided in the Loan
          Documents shall not be deemed a waiver of such right, remedy or option
          or of any covenant or obligation secured by the Loan Documents. No
          acceptance by Lender or Trustee of any payment after the occurrence of
          an Event of Default and no payment by Lender or Trustee of any Advance
          or obligation for which Borrower is liable hereunder shall be deemed
          to waive or cure such Event of Default or Borrower's liability to pay
          such obligation. No sale of all or any portion of the Mortgaged
          Property, no forbearance on the part of Lender or Trustee, and no
          extension of time for the payment of the whole or any portion of the
          Indebtedness or any other indulgence given by Lender or Trustee to
          Borrower or any other person or entity, shall operate to release or in
          any manner affect Lender's or Trustee's interest in the Mortgaged
          Property or the liability of Borrower to pay the Indebtedness, except
          to the extent that such liability shall be reduced by Proceeds of the
          sale of all or any portion of the Mortgaged Property received by
          Lender. No waiver by Lender or Trustee shall be effective unless it is
          in writing and then only to the extent specifically stated.

                    (f) No Impairment; No Release. The interests and rights of
          Lender or Trustee under the Loan Documents shall not be impaired by
          any indulgence, including (i) any renewal, extension or modification
          which Lender may grant with respect to any of the Indebtedness; (ii)
          any surrender, compromise, release, renewal, extension, exchange or
          substitution which Lender or Trustee may grant with respect to the
          Mortgaged Property or any portion thereof; or (iii) any release or
          indulgence granted to any maker, endorser, guarantor or surety of any
          of the Indebtedness. If the Mortgaged Property is sold and Lender
          enters into any agreement with the then owner of the Mortgaged
          Property extending the time of payment of the Indebtedness, or
          otherwise modifying the terms hereof or of any other Loan Document,
          Borrower shall continue to be liable to pay the 


                                       46
<PAGE>   52

          Indebtedness according to the tenor of any such agreement unless
          expressly released and discharged in writing by Lender.

                    (g) Waivers and Agreements Regarding Remedies. To the
          fullest extent that Borrower may legally do so, Borrower:

                              (i) AGREES THAT BORROWER WILL NOT AT ANY TIME
                    INSIST UPON, PLEAD, CLAIM OR TAKE THE BENEFIT OR ADVANTAGE
                    OF ANY LAWS NOW OR HEREAFTER IN FORCE PROVIDING FOR ANY
                    APPRAISAL OR APPRAISEMENT, VALUATION, STAY, EXTENSION OR
                    REDEMPTION, AND WAIVES AND RELEASES ALL RIGHTS OF
                    REDEMPTION, VALUATION, APPRAISAL OR APPRAISEMENT, STAY OF
                    EXECUTION, EXTENSION AND NOTICE OF ELECTION TO ACCELERATE OR
                    DECLARE DUE THE WHOLE OF THE INDEBTEDNESS;

                              (ii) WAIVES ALL RIGHTS TO A MARSHALLING OF THE
                    ASSETS OF BORROWER, INCLUDING THE MORTGAGED PROPERTY, OR TO
                    A SALE IN INVERSE ORDER OF ALIENATION IN THE EVENT OF
                    FORECLOSURE OF THE INTERESTS HEREBY CREATED, AND AGREES NOT
                    TO ASSERT ANY RIGHT UNDER ANY LAWS PERTAINING TO THE
                    MARSHALLING OF ASSETS, THE SALE IN INVERSE ORDER OF
                    ALIENATION, HOMESTEAD EXEMPTION, THE ADMINISTRATION OF
                    ESTATES OF DECEDENTS, OR ANY OTHER MATTERS WHATSOEVER TO
                    DEFEAT, REDUCE OR AFFECT THE RIGHT OF LENDER UNDER THE LOAN
                    DOCUMENTS TO A SALE OF THE MORTGAGED PROPERTY FOR THE
                    COLLECTION OF THE INDEBTEDNESS WITHOUT ANY PRIOR OR
                    DIFFERENT RESORT FOR COLLECTION, OR THE RIGHT OF LENDER OR
                    TRUSTEE TO THE PAYMENT OF THE INDEBTEDNESS OUT OF THE
                    PROCEEDS OF SALE OF THE MORTGAGED PROPERTY IN PREFERENCE TO
                    EVERY OTHER CLAIMANT WHATSOEVER;

                              (iii) WAIVES ANY RIGHT TO BRING OR UTILIZE ANY
                    DEFENSE, COUNTERCLAIM OR SETOFF, OTHER THAN ONE IN GOOD
                    FAITH, WHICH DENIES THE EXISTENCE OR SUFFICIENCY OF THE
                    FACTS UPON WHICH THE FORECLOSURE ACTION IS GROUNDED OR WHICH
                    IS BASED ON LENDER'S OR TRUSTEE'S WRONGFUL ACTIONS. IF ANY
                    DEFENSE, COUNTERCLAIM OR SETOFF (OTHER THAN ONE PERMITTED BY
                    THE PRECEDING SENTENCE) IS RAISED BY BORROWER IN SUCH
                    FORECLOSURE ACTION, SUCH DEFENSE, COUNTERCLAIM OR SETOFF
                    SHALL BE DISMISSED. IF SUCH DEFENSE, COUNTERCLAIM OR SETOFF
                    IS BASED ON A CLAIM WHICH COULD BE TRIED IN AN ACTION FOR
                    MONEY DAMAGES, THE FOREGOING WAIVER SHALL NOT BAR A SEPARATE
                    ACTION FOR SUCH DAMAGE (UNLESS SUCH CLAIM IS REQUIRED BY LAW
                    OR APPLICABLE RULES OF PROCEDURE TO BE PLEADED IN OR
                    CONSOLIDATED WITH THE ACTION INITIATED BY LENDER OR
                    TRUSTEE), BUT SUCH SEPARATE ACTION SHALL NOT THEREAFTER BE
                    CONSOLIDATED WITH LENDER'S OR TRUSTEE'S FORECLOSURE ACTION.
                    THE

<PAGE>   53

                    BRINGING OF SUCH SEPARATE ACTION FOR MONEY DAMAGES SHALL NOT
                    BE DEEMED TO AFFORD ANY GROUNDS FOR STAYING ANY SUCH
                    FORECLOSURE ACTION;

                              (iv) WAIVES AND RELINQUISHES ANY AND ALL RIGHTS
                    AND REMEDIES WHICH BORROWER MAY HAVE OR BE ABLE TO ASSERT BY
                    REASON OF THE PROVISIONS OF ANY LAWS PERTAINING TO THE
                    RIGHTS AND REMEDIES OF SURETIES;

                              (v) WAIVES THE DEFENSE OF LACHES AND ANY
                    APPLICABLE STATUTES OF LIMITATION; AND

                              (vi) WAIVES ANY RIGHT TO HAVE ANY TRIAL, ACTION OR
                    PROCEEDING TRIED BY A JURY.

                    (h) Lender's Discretion. Lender may exercise its rights,
          options and remedies and except as provided herein may make all
          decisions, judgments and determinations under this Deed of Trust and
          the other Loan Documents in its sole unfettered discretion.

                    (i) Recitals of Facts. In the event of a sale or other
          disposition of the Mortgaged Property pursuant to Section 4.2 and the
          execution of a deed or other conveyance pursuant thereto, the recitals
          therein of facts (such as default, the giving of notice of default and
          notice of sale, demand that such sale should be made, postponement of
          sale, terms of sale, purchase, payment of purchase money and other
          facts affecting the regularity or validity of such sale or
          disposition) shall be conclusive proof of the truth of such facts. Any
          such deed or conveyance shall be conclusive against all persons as to
          such facts recited therein.

                    (j) Lender's Right to Waive, Consent or Release. Lender may
          at any time, in writing, (i) waive compliance by Borrower with any
          covenant herein made by Borrower to the extent and in the manner
          specified in such writing; (ii) consent to Borrower's doing any act
          which Borrower is prohibited hereunder from doing, or consent to
          Borrower's failing to do any act which Borrower is required hereunder
          to do, to the extent and in the manner specified in such writing; or
          (iii) release or require Trustee to release any portion of the
          Mortgaged Property, or any interest therein, from this Deed of Trust
          and the lien of the other Loan Documents. No such act shall in any way
          impair the rights of Lender or Trustee hereunder except to the extent
          specified by Lender in such writing.

                    (k) Possession of the Mortgaged Property. Upon the
          occurrence and during the continuance of any Event of Default
          hereunder which permits acceleration of the Loan and demand by Lender
          at its option, Borrower shall 


                                       48
<PAGE>   54

          immediately surrender or cause the surrender of possession of the
          Premises to Lender. If Borrower is permitted to remain in possession,
          such possession shall be as tenant of Lender and Borrower (i) shall on
          demand pay to Lender monthly, in advance, reasonable use and occupancy
          charges for the space so occupied, and (ii) in default thereof, may be
          dispossessed by the usual summary proceedings. Upon demand, Borrower
          shall assemble the Collateral and make it available at any place
          Lender may designate to allow Lender to take possession and/or dispose
          of the Collateral. The covenants herein contained may be enforced by a
          receiver of the Mortgaged Property or any portion thereof. Nothing in
          this Section 4.3(k) shall be deemed a waiver of the provisions of this
          Deed of Trust prohibiting the sale or other disposition of the
          Mortgaged Property without Lender's consent.

                      (l) Limitations on Liability

                              (i) Subject to the provisions of this Section, in
                    any action or proceedings brought on this Deed of Trust, the
                    Note or on any of the Loan Documents in which a money
                    judgment is sought, Lender and Trustee will look solely to
                    the Mortgaged Property and other property described in the
                    Loan Documents (including the Property Income and any other
                    rents and profits from such property) which is collateral
                    for payment of the Indebtedness and, specifically and
                    without limitation, Lender and Trustee agree to waive any
                    right to seek or obtain a deficiency judgment against
                    Borrower or to seek or obtain personal judgment for the
                    payment of money representing principal or interest of the
                    Loan.

                              (ii) The provisions of Section 4.3(l)(i) shall not

                                  (u) except as expressly set forth herein,
                                  constitute a waiver, release or impairment of
                                  any obligation evidenced or secured by this
                                  Deed of Trust, the Note or any other Loan
                                  Document by either Lender or Trustee;

                                  (v) be deemed to be a waiver of any right
                                  which Lender or Trustee may have under
                                  Sections 506(a), 506(b), 1111(b) or any other
                                  provisions of the U.S. Bankruptcy Code to file
                                  a claim for the full amount of the
                                  Indebtedness secured by this Deed of Trust or
                                  to require that all Collateral shall continue
                                  to secure all of the Indebtedness owing to
                                  Lender in accordance

                                  or suit for judicial foreclosure and sale
                                  under this Deed of Trust but no monetary
                                  judgment for a deficiency money judgment may
                                  be entered or enforced against Borrower;

                                  (x) affect the validity or enforceability of,
                                  or limit recovery under, any indemnity
                                  (including the environmental indemnity set
                                  forth in Section 2.20(f) of this Deed of Trust
                                  or any separate environmental indemnity
                                  agreement, however designated), guaranty,

                                  Documents;

                                  to obtain the appointment of a receiver; or,

                                  (z) impair Lender's or Trustee's rights and
                                  remedies under Section 2.19 of this Deed of

                    Subsection 4.3(1), nothing herein shall be deemed to impair
                    or prejudice in any way the right of Lender or Trustee
                    (which right is specifically reserved) to pursue or obtain
                    personal recourse liability against Borrower to recover
                    Losses incurred by Lender or Trustee arising out of or
                    resulting from:

                              Property, thereby resulting in, or contributing
                              materially to an Event of Default. Provided,
                              however, that neither Borrower nor any other
                              person or entity shall have any recourse liability
                              for Losses based on distributions by Borrower of
                              Property Income or rent loss insurance Proceeds to
                              Borrower, or any general partner, principal,

                              Borrower (if Borrower shall be a limited liability
                              company) made in good faith (after determining the
                              sufficiency of Property Income and rent loss
                              insurance Proceeds to cover the payments due under
                              the Loan Documents and the operating expenses of

                              Default.

                         (iv) Notwithstanding the foregoing, the agreement
               of Lender and Trustee not to pursue recourse liability against
               Borrower as set forth in this Section 4.3(l)(i) above SHALL
               AUTOMATICALLY BECOME NULL AND VOID as to Borrower and be of no
               further force and effect in the event Borrower, any general
               partner or member (if

                              Borrower or any guarantor of the Indebtedness

                              under the U.S. Bankruptcy Code respecting its or
                              their debts, or any such petition shall have been
                              filed against any of the foregoing which is not
                              dismissed within 90 days of such filing.

                              (m) Subrogation. If all or any portion of the
               proceeds of the Note or any Advance shall be used directly or
               indirectly to pay off, discharge or satisfy, in whole or in part,
               any prior lien or encumbrance upon the Mortgaged Property or any
               portion thereof, then Lender and Trustee shall be subrogated to,
               and shall have the benefit of the priority of, such other lien or
               encumbrance and any additional security held by the holder
               thereof.

of Lender, Trustee may at any time (a) reconvey all or any portion of the
Mortgaged Property, (b) consent to the making of any map or plat thereof, (c)
join in granting any easement thereon or in creating any covenants or conditions
restricting the use or occupancy thereof, or (d) join in any extension agreement
or in any agreement subordinating the lien or charge hereof. Any such action may
be taken by Trustee without notice, and shall not affect the personal liability
of any person for the payment of the Indebtedness or the lien of this Deed of
Trust upon the Mortgaged Property for the full amount of the Indebtedness.

               Section 5.2 Reconveyance. Upon the written request of Lender

acceptance hereof, covenants faithfully to perform and fulfill the trust herein
created, being liable, however, only for negligence or willful misconduct.
Trustee hereby waives any statutory fee and shall be entitled to, and hereby
agrees to accept, reasonable compensation in lieu thereof for all services
rendered or expenses incurred in the administration or execution of the trust
hereby created. Borrower hereby agrees to pay such compensation subject to any
applicable legal limitations.

               Section 5.4 Substitution of Trustee. Lender at any time in its
sole discretion may select and appoint a successor or substitute Trustee
hereunder by instrument in writing in any manner now or hereafter provided by
law. Such writing, upon recordation in the county where the Land is located,
shall be conclusive proof of 


                                       52
<PAGE>   58

proper substitution of such successor or substitute
Trustee which shall thereupon and without conveyance from the predecessor
Trustee succeed to all its title, estate rights, powers and duties.

        may be, in a written notice to the other party in the manner provided
        for in this Section 6.1. A notice shall be deemed to have been given: in
        the case of hand delivery, at the time of delivery; in the case of

        under this Section 6.1 may elect to waive any deficiencies and treat the
        notice as having been properly given.

                      (b) Borrower shall notify Lender promptly of the
        occurrence of any of the following: (i) receipt of notice from any
        governmental authority materially and adversely affecting the Mortgaged
        Property; (ii) receipt of any notice from the holder of any other lien

        or any guarantor, or any other action by any creditor thereof as a
        result of any default 


                                       53
<PAGE>   59

under the terms of any loan if such action could reasonably be expected to have
a material adverse effect on Borrower or the Mortgaged Property.

               Section 6.2 Binding Obligations; Joint and Several. The
provisions and covenants of this Deed of Trust shall run with the land, shall be
binding upon Borrower, its successors and assigns, and shall inure to the
benefit of Lender and Trustee and their respective successors and assigns. If
there is more than one Borrower, all their obligations and undertakings
hereunder are and shall be joint and several.

               Section 6.3 Captions. The captions of the sections and
subsections of this Deed of Trust are for convenience only and are not intended

acknowledge and deliver, at its sole cost and expense, such further acts,

other Loan Document.

               Section 6.5 Severability. If any one or more of the provisions
contained in this Deed of Trust shall for any reason be held to be invalid,
illegal or unenforceable in any respect, such invalidity, illegality or
unenforceability shall not affect any other provision of this Deed of Trust, but
this Deed of Trust shall be construed as if such invalid, illegal or
unenforceable provision had never been contained herein.

Borrower hereunder shall be paid without notice, demand, counterclaim, setoff,
deduction or defense and without abatement, suspension, deferment, diminution or

way be released, discharged, or otherwise affected (except as expressly provided
herein) by reason of: (a) any damage to or destruction of or any condemnation or
similar taking of the Mortgaged Property or any portion thereof; (b) any
restriction or prevention of or interference with any use of the Mortgaged
Property or any portion thereof; (c) any title defect or encumbrance or any

court, in any such proceeding; (e) any claim which Borrower has or might
have against Lender or Trustee; (f) any default or failure on the part of Lender
or Trustee to perform or comply with any of the terms hereof or of any other
agreement with Borrower; or (g) any other occurrence whatsoever, whether similar
or dissimilar to the foregoing, whether or not Borrower shall have notice or
knowledge of any of the foregoing. Except as expressly provided herein, Borrower
waives all rights now or hereafter conferred by statute or otherwise to any
abatement, suspension, deferment, diminution or reduction of any sum secured
hereby and payable by Borrower.

               Section 6.7 Amendments. This Deed of Trust cannot be altered,
amended, modified or discharged orally and no executory agreement shall be
effective to modify or discharge it in whole or in part, unless in writing and
signed by the party against which enforcement is sought.

               Section 6.8 Other Loan Documents and Schedules. All of the
agreements, conditions, covenants, provisions and stipulations contained in the
Note and the other Loan Documents, and each of them, which are to be kept and
performed by Borrower are hereby made a part of this Deed of Trust to the same
extent and with the same force and effect as if they were fully set forth in
this Deed of Trust, and Borrower shall keep and perform the same, or cause them
to be kept and performed, strictly in accordance with their respective terms.
The Cover Sheet and each schedule and rider attached to this Deed of Trust are
integral parts of this Deed of Trust and are incorporated herein by this
reference. In the event of any conflict between the provisions of any such
schedule or rider and the remainder of this Deed of Trust, the provisions of
such schedule or rider shall prevail.

               Section 6.9 Legal Construction.

                      (a) The enforcement of this Deed of Trust shall be
        governed by, and construed and interpreted in accordance with, the laws
        of the State.

                      (b) All terms contained herein shall be construed,
        whenever the context of this Deed of Trust so requires, so that the
        singular number shall include the plural, and the plural the singular,
        and the use of any gender shall include all genders.

                      (c) The terms "include" and "including" as used in this
        Deed of Trust shall be construed as if followed by the phrase "without
        limitation."

                      (d) Any provision of this Deed of Trust permitting the
        recovery of attorneys' fees and costs shall be deemed to include such
        fees and costs incurred in all appellate proceedings.

               Section 6.10 Merger. So long as any Indebtedness shall remain
unpaid, fee title to and any other estate in the Mortgaged Property shall not
merge, but shall be kept separate and distinct, notwithstanding the union of
such estates in any person or entity.

               Section 6.11 Time of the Essence. Time shall be of the essence in
the performance of all obligations of Borrower under this Deed of Trust.

               Section 6.12 Reconveyance. If all of the Indebtedness is paid in
full in accordance with the Note and the other Loan Documents, then in that
event only all rights of Lender and Trustee under this Deed of Trust and the
other Loan Documents shall terminate and the Mortgaged Property shall become
wholly clear of the liens, grants, security interests, conveyances and
assignments evidenced hereby and thereby, and Lender shall release or cause to
be released such liens, grants, assignments, conveyances and security interests
in due form at Borrower's cost (to the extent permitted by the law of the
State), and this Deed of Trust shall be void; provided, however, that no
provision of this Deed of Trust or any other Loan Document which, by its own
terms, is intended to survive such payment, performance, and release (nor the
rights of Lender or Trustee under any such provision) shall be affected in any
manner thereby and such provision shall, in fact, survive. Recitals of any
matters or facts in any release instrument executed by Lender or Trustee under
this Section 6.12 shall be conclusive proof of the truthfulness thereof. To the
extent permitted by law, such an instrument may describe the grantee or releasee
as "the person or persons legally entitled thereto" and Lender and Trustee shall
not have any duty to determine the rights of persons claiming to be rightful
grantees or releasees of any of the Mortgaged Property. When this Deed of Trust
has been fully released or discharged by Lender and/or Trustee, the release or
discharge hereof shall operate as a release and discharge of the Assignment and
as a reassignment of all future Leases and Property Income with respect to the
Mortgaged Property to the person or persons legally entitled thereto, unless
such release expressly provides to the contrary.

               Section 6.13 Partial Reconveyance. After disbursement of the
principal of the Loan, Borrower shall be entitled to obtain partial reconveyance
of entire properties encumbered by this Deed of Trust (but not portions of such
properties) from the liens of this Deed of Trust on the following terms and
conditions:

                             (1) A release under this Section 6.13 may not take
               place more than three (3) times during the term of the Loan;

                             (2) The property to be reconveyed shall constitute
               an entire real estate development, comprising one of the
               properties encumbered by 


                                       56
<PAGE>   62

                this Mortgage and indicated by a separate underlined caption in
                the legal description attached as Schedule A;

                             (3) No more than five (5) properties may be
               released under this Section 6.13, and no more than a total of
               five (5) properties may be released under this Section 6.13 and
               Section 6.15;

                             (4) After the proposed release, the Debt Service
               Coverage Ratio ("DSC") of the Loan, calculated with respect to
               all portions of the Mortgaged Property other than the property
               to be released and taking into account the prepayment of the
               Loan, both for the twelve (12) consecutive calendar months prior
               to the release and as projected for the twelve (12) months
               following the release, must be at least equal to or greater than
               the greater of (a) 1.60:1 or (b) the current DSC of the existing
               Mortgaged Property including the property to be released
               calculated for the prior twelve (12) consecutive calendar months
               prior to release;

                             (5) After the proposed release, the Loan to Value
               ("LTV") of the Loan must be less than or equal to the lesser of
               a) sixty-five percent (65%) or (b) the current LTV of the
               existing Mortgaged Property including the property to be released
               calculated immediately prior to the release based upon appraisals
               in form and content satisfactory to Lender, prepared by an MAI
               appraiser approved by Lender and furnished to Lender at
               Borrower's cost;

                             (6) Borrower shall pay to Lender in reduction of
               the principal balance of the Loan, a sum equal to one hundred
               twenty five percent (125%) of the original Allocated Loan Amount
               (as shown in Schedule C) for the property to be released, plus a
               Prepayment Premium calculated with respect to such Allocated Loan
               Amount, computed in the manner specified in Section 9.1 of the
               Note; if the partial release occurs prior to the time Borrower
               may prepay the Loan under Section 9.1 of the Note, there shall
               nevertheless be charged a Prepayment Premium relative to the
               partial release calculated as though such prepayment privilege
               were in effect;

                             (7) In no event may any partial release result in
               the reduction of the principal balance of the Loan below
               FIFTY-SEVEN MILLION FIVE HUNDRED THOUSAND AND NO/100 DOLLARS
               ($57,500,000);

                             (8) Lender may at its sole discretion reject any
               property release that, in Lender's sole determination, would
               render the remaining 


                                       57
<PAGE>   63

                Mortgaged Property not in compliance with the terms and
                provisions of that certain Application for Real Estate Loan
                executed by "Arden Realty Ltd. Partnership" and Lender with
                respect to the Loan (the "APPLICATION") the Loan Documents, or
                would be detrimental to the overall quality and/or value of the
                remaining Mortgaged Property;

                        (9) No Event of Default shall have occurred and be
                continuing at the time such request for release is made or at
                the time of the release, nor shall any event have occurred and
                be continuing at the time of release which, after notice or
                passage of time or both, would constitute an Event of Default;

                        (10) Borrower shall furnish to Lender, at Borrower's
                sole cost, an indorsement to the title insurance policy which
                insures the continued validity and priority of the Mortgage on
                all remaining properties encumbered thereby, notwithstanding
                such partial reconveyance.

                        (11) Borrower must pay all of Lender's reasonable costs
                associated with the partial release (including without
                limitation legal fees, appraisal fees, costs of market studies,
                title insurance premiums, engineering fees, recording fees and
                taxes) plus a fee of one percent (1%) of the original Allocated
                Loan Amount for the property to be released as shown on Schedule
                C attached hereto;

                        (12) The original Borrower named in the Loan Documents
                continues to be the owner of the remaining Mortgaged Property;
                and

                        (13) All documents relating to the release shall be in
                form and substance reasonably satisfactory to Lender.

                Borrower shall have the right to obtain partial reconveyance of
that portion of the Mortgaged Property described in Schedule A under the caption
"2730 Wilshire Boulevard," which portion is described as Lot 2 in Tentative
Tract Map No. 24932, prepared by Psomas and Associates and dated April 16, 1997,
with revisions September 15, 1997, October 2, 1997, June 30, 1998 and August 5,
1998, as that description may be altered subject to the reasonable approval of
Lender (the "Free Release Parcel"), upon satisfaction of the following
conditions:

                        (1) No Event of Default shall have occurred and be
                continuing at the time of request for such reconveyance or at
                the time of the release, nor shall any event have occurred and
                be continuing at the time of release which, after notice or
                passage of time or both, would constitute an Event of Default;

<PAGE>   64

                        (2) Borrower shall furnish to Lender evidence that the
                Free Release Parcel and the remaining portions of the "2730

                in compliance with all subdivision laws and ordinances,
                including without limitation the California Subdivision Map Act;

                        (3) Borrower shall furnish to Lender, at Borrower's sole
                cost, an indorsement to the title insurance policy which insures
                the continued validity and priority of the Mortgage on all
                remaining properties encumbered thereby, notwithstanding such
                partial reconveyance;

                        (4) Borrower shall establish to Lender's reasonable
                satisfaction that the Retained Office Parcel shall have access
                to public streets, and that such access, all easements, rights
                of way, rights of ingress and egress, parking rights and
                arrangements for maintenance and operation of (and, if
                applicable, sharing of costs of maintenance and operation of)
                the Free Release Parcel and the Retained Office Parcel are in
                place and are reasonably satisfactory to Lender; and

                        (5) Borrower must pay all of Lender's reasonable costs
                associated with the partial reconveyance (including, without
                limitation, legal fees, title insurance premiums, engineering
                fees, recording fees and taxes).

        required pursuant to this Section and a perfected security interest in
        and lien on the U.S. Obligations purchased pursuant hereto and the

        not cause any Rating Agency to withdraw, qualify or downgrade the
        then-applicable rating on any security issued in connection with any
        Securitization and (y) a certificate from an independent certified
        public accountant that is a member in good standing of the AICPA, is
        subject to peer review, and is otherwise reasonably acceptable to
        Lender, certifying that the amounts of the U.S. Obligations comply with

<PAGE>   66

                (d) The U.S. Obligations shall mature on or be redeemable, or
        provide for payment thereon, on or prior to the Business Day immediately
        preceding the date on which payments under the Note are due and payable
        and the proceeds thereof shall be payable directly to the Lender. In
        connection with the foregoing, Borrower appoints the Lender as
        Borrower's agent for the purpose of applying the amounts delivered
        pursuant to clause (c)(iv) above to purchase U.S. Obligations.

                (e) If any notice of defeasance is given, Borrower shall be
        required to defease the Loan on the specified Payment Date (unless such
        notice is revoked in writing by Borrower prior to the date specified

               Section 6.15  Substitution of Mortgaged Property

               After disbursement of the principal of the Loan, Borrower shall
be entitled to substitute a property (defined as releasing a property that then
constitutes Mortgaged Property (the "RELEASED PROPERTY") and substituting
another property owned in fee by Borrower (the "SUBSTITUTE PROPERTY") in its
place on the following terms and conditions:

                             (1) A substitution may not take place more than two
               (2) times during the term of the Loan;

                             (2) No more than three (3) properties may be
               released under this Section 6.15 and no more than a total of five
               (5) properties may be released under Section 6.13 and this
               Section 6.15;

                             (3) After the proposed substitution, the Debt
               Service Coverage Ratio ("DSC") of the Loan, calculated so as to
               include the Substitute Property (in place of the Released
               Property) and the remaining Mortgaged Property, both for the
               twelve (12) months prior to the substitution and as projected for
               the twelve (12) months following the substitution, must be at
               least equal to or greater than the greater of 


                                       61
<PAGE>   67

                (a) 1.60:1 or (b) the current DSC of the existing Mortgaged
                Property including the Released Property (and not including the
                Substitute Property) calculated for the prior twelve (12) months
                period prior to the substitution;

                        (4) After the proposed substitution, the Loan to Value
                ("LTV") of the Loan must be less than or equal to the lesser of
                (a) sixty-five percent (65%) or (b) the current LTV of the
                existing Mortgaged Property including the property to be
                released calculated immediately prior to the substitution based
                upon appraisals in form and substance satisfactory to Lender,
                prepared by an MAI appraiser approved by Lender and furnished to
                Lender at Borrower's cost;

                        (5) The net operating income and/or rental rates of the
                Substitute Property must not show a downward trend for any of
                the three (3) years prior to the substitution;

                        (6) The appraised value (based upon appraisals furnished
                to Lender in form and substance satisfactory to Lender and
                prepared by an MAI appraiser approved by Lender at Borrower's
                cost), the net operating income and current DSC of the
                Substitute Property must be at least one hundred twenty-five
                percent (125%) of the appraised value, net operating income and
                the DSC of the Released Property. (For purposes hereof, the DSC
                shall be calculated for the Released Property and the Substitute
                Property on the basis of the Allocated Loan Amounts of each);

                        (7) Lender may at its sole discretion reject any
                property substitution that, in Lender's sole determination,
                would not be in compliance with the conditions for approval and
                acceptance of collateral reflected in the Application and the
                terms and provisions of the Loan Documents, would be detrimental
                to the overall quality and/or value of the Mortgaged Property,
                or would not be in compliance with Lender's then existing
                underwriting standards and criteria. The Substitute Property
                must be located in California and must be one hundred percent
                (100%) multi-tenant office with no "flex space" or "R & D"
                buildings;

                        (8) Borrower must pay all of Lender's costs associated
                with the substitution plus a fee of one percent (1%) of the
                original Allocated Loan Amount for the Released Property, as
                shown on Schedule C hereto;

                        (9) No Event of Default shall exist at the time such
                request for substitution is made or on the date of the
                completion of the substitution, nor shall any event have
                occurred and be continuing at the time of release 



                                       62
<PAGE>   68

                which, after notice or passage of time or both, would constitute
                an Event of Default;

                        (10) After the proposed substitution, no more than
                twelve percent (12%) of the total square foot area of the
                buildings comprising the Mortgaged Property may be occupied by
                tenants occupying an entire, or substantially entire, building;

                        (11) After giving effect to the substitution and
                release, the original Borrower named in the Loan Documents
                continues to be the owner of the Mortgaged Property;

                        (12) In order to substitute one property for another as
                security for the Loan, Borrower and Lender must go through many
                of the same steps required to close the Loan initially. Solely
                for purposes of illustration and without limitation,
                environmental assessments must be performed and analyzed; leases
                must be obtained and reviewed and tenant estoppel letters
                obtained; the status of title to the property must be evaluated
                and title insurance obtained, including but not limited to any
                title policy endorsement required by Lender insuring that the
                release will not impair Lender's coverage under its then
                existing title policy as to the land remaining under the
                Mortgage; plans and specifications must be obtained and
                reviewed; satisfactory evidence of compliance obtained, etc. All
                documents relating to the substitution shall be in form and
                substance reasonably satisfactory to Lender. Any property to be
                substituted must comply with all of the terms and conditions
                reflected in the Application for the appraisal, inspection,
                engineering review, evaluation and approval by Lender of the
                original collateral for the Loan. In connection with that
                process of appraisal, inspection, engineering review, evaluation
                and approval, Lender may engage one or more consultants.
                Borrower shall reimburse Lender, within ten (10) days after
                written notice making demand therefor, for the fees and expenses
                charged by such consultants. Borrower shall also pay, within ten
                (10) days after written notice making demand therefor, all other
                costs charged or incurred by Lender in connection with or
                arising from any request for property substitution, whether or
                not such substitution is actually approved or completed,
                including without limitation, legal fees, appraisal fees, costs
                of market studies, title insurance premiums, engineering fees,
                recording fees and taxes.

                    Section 6.16  Cash Flow Deposit Account

                        (a) If, at any time during the term of the Loan (1) for
                two consecutive quarters, the Debt Service Coverage Ratio
                ("DSC") for the Mortgaged Property is less than 1.30:1, or (2)
                Borrower fails to deliver the Quarterly Financial Statement
                required to be furnished pursuant to Section 2.16 as and when
                due, or (3) an Event of Default occurs which permits Lender to
                accelerate the Note, then, upon written notice by Lender to
                Borrower, Borrower will be obligated to notify all tenants under
                leases for any portion of the Mortgaged Property that all rents
                and other income assigned to Lender under the Mortgage (and the
                Assignments of Leases and Rents) shall be paid as directed by
                Lender into an interest-bearing deposit account in the name of
                Borrower (the "CASH FLOW DEPOSIT ACCOUNT") from which
                withdrawals may not be made without the written authorization of
                Lender, maintained at a bank or other financial institution
                approved by Lender. If Borrower receives any such rents or other
                income at any time during which such amounts are required
                pursuant to this Section 6.16(a) to be paid into the Cash Flow
                Deposit Account, Borrower shall promptly and in any event within
                ten (10) days deposit such amounts into the Cash Flow Deposit
                Account. The Cash Flow Deposit Account and all funds from time
                to time therein shall be subject to a first priority pledge and
                security interest in favor of Lender, as collateral security for
                the Indebtedness and the other obligations under the Note and
                the other Loan Documents, pursuant to documents approved by
                Lender. Borrower shall take such actions and execute such
                documents as may be reasonably required by Lender in order to
                create, evidence and perfect such pledge and security interest.
                Disbursements or withdrawals from the Cash Flow Deposit Account
                shall, subject to Section 6.16(b), be made only upon written
                request therefor by Borrower and written consent thereto by
                Lender. Lender shall consent to payment of normal and customary
                operating expenses of the Mortgaged Property including, without
                limitation, utility costs, cleaning costs, management fees for
                the Mortgaged Property (but only to the extent not exceeding
                four percent (4%) of gross rents), leasing commissions and
                expenses, real estate taxes, capital expenditures, tenant
                improvement costs, all pursuant to a budget and capital
                expenditures program submitted to and approved by Lender (which
                approval shall not be unreasonably withheld or delayed), and
                payments due on the Loan. So long as the Cash Flow Deposit
                Account remains active, Borrower shall pay to Lender as a
                servicing fee (the "Servicing Fee") on the first day of each
                month a sum equal to Six Thousand and No/100 Dollars ($6,000),
                and shall pay to the depository of the Cash Flow Deposit Account
                (or reimburse Lender within ten (10) days after written demand
                therefor, to the extent the same are paid by Lender) any fees or
                other amounts charged by such depository.

<PAGE>   70

                        (b) Monthly payments required on the Loan and under the
                Loan Documents, including principal and interest payments, the
                Servicing Fee and payments for real estate taxes and
                assessments, insurance and other escrows will be deducted
                automatically from the Cash Flow Deposit Account on the first
                day of each month. Provided that no Event of Default has
                occurred and is continuing and no event which, with notice or
                the passage of time or both, would constitute an Event of
                Default has occurred and is continuing, Lender will also
                authorize disbursements from the Cash Flow Deposit Account
                within seven (7) business days of a written request therefor,
                for items contained in the approved budget and capital
                expenditures program accompanied by supporting documentation
                reasonably satisfactory to Lender for the items thus requested.
                Interest on funds in the Cash Flow Deposit Account will accrue
                to the benefit of Borrower and will be retained in the Cash Flow
                Deposit Account. Upon the occurrence of an Event of Default,
                Lender, at is option, may apply the funds then on deposit in the
                Cash Flow Deposit Account to pay expenses of the Mortgaged
                Property or against the then balance of the Indebtedness.

                        (c) Provided that no Event of Default has occurred which
                permits acceleration of the Loan for four (4) consecutive
                calendar quarters after activation of the Cash Flow Deposit
                Account, and the DSC at the end of each of those quarters, as
                shown on financial statements for each of those quarters
                prepared in accordance with generally accepted accounting
                principles, certified to Lender by the managing partner or
                member of Borrower or chief financial officer of Borrower and
                delivered to Lender along with a current rent roll for the
                Mortgaged Property certified to Lender by the same person,
                equals or exceeds 1.40:1, then the requirement for payment of
                revenues to the Cash Flow Deposit Account will be suspended and
                all funds then on deposit in the Cash Flow Deposit Account shall
                be paid to Borrower. The requirement for the Cash Flow Deposit
                Account may be reinstated on any later date during the term of
                the Loan in accordance with the provisions of Section 6.16(a).

                    Section 6.17 Performance Reserve Account. Upon execution of 
this Promissory Note, Borrower shall deposit Three Million and No/100 Dollars
($3,000,000) into an interest-bearing deposit account (the "PERFORMANCE RESERVE
ACCOUNT") from which withdrawals may not be made without the written
authorization of Lender, maintained at a bank or other financial instruction
approved by Lender. The Performance Reserve Account and all funds from time to
time therein shall be subject to a first priority pledge and security interest
in favor of Lender, as collateral security for the Indebtedness and the other
obligations under the Note and the other Loan Documents pursuant to documents
approved by Lender. Borrower shall take such actions and execute such documents
as may be reasonably required by Lender in order to create, evidence and perfect
such pledge and security interest. 


                                       65
<PAGE>   71

Interest on the funds in the Performance Reserve Account shall accrue to the
benefit of Borrower and shall, so long as no Event of Default has occurred and
is continuing which permits acceleration of the Loan to Borrower, upon request
by Borrower, not more than once per calendar quarter. Upon the occurrence of an
Event of Default which permits acceleration of the Loan, the funds in the
Performance Reserve Account may be withdrawn by Lender from the Performance
Reserve Account on Lender's sole demand, irrespective of any conflicting notice
or demand by or on behalf of Borrower, and may be applied in whole or in part by
Lender, in its sole discretion to the cure of such Event of Default, or to the
payment of the Indebtedness, or may continue to be held by Lender as additional
collateral, or any combination of the foregoing.

                            APPLICABLE LAW PROVISIONS

        Pursuant to the provisions of Section 6.8 of this Deed of Trust, this
Rider and the following terms and provisions are hereby attached to,
incorporated into and made a part of this Deed of Trust.

        1. Trustor requests that a copy of any notice of default and of any
notice of sale hereunder shall be mailed to Trustor at its address set forth
above.

        2.     (a) If the maturity of the Note is accelerated by Beneficiary 
because of the occurrence of an Event of Default, as provided therein, such
default and the resulting acceleration shall be deemed to be an election on the
part of Trustor to prepay the Note. Accordingly, there shall be added to the
amount due after default and acceleration the Prepayment Premium (as defined in
the Note), calculated as set forth in the Note and using as the prepayment date
the date on which any tender of payment is made, and Trustor agrees to pay the
same. Any tender of payment thereafter made by or on behalf of Trustor
(including, without limitation, payment by any guarantor or purchaser at a
foreclosure sale) shall include the Prepayment Premium computed as provided in
the Note. In the event such default, acceleration and tender occur prior to the
time Trustor may prepay the Note, there shall nevertheless be due and added the
Prepayment Premium calculated in the manner set forth in the Note as though such
prepayment privilege were in effect.

               (b) The Prepayment Premium shall be paid without prejudice to the
right of Beneficiary to collect any other amounts provided to be paid under the
Note or the other Loan Documents.

               (c) TRUSTOR HEREBY EXPRESSLY (A) WAIVES ANY RIGHTS TRUSTOR MAY
HAVE UNDER CALIFORNIA CIVIL CODE SECTION 2954.10 TO PREPAY THE NOTE, IN WHOLE OR
IN PART, WITHOUT PENALTY, UPON ACCELERATION OF THE MATURITY DATE, AND (B) EXCEPT
AS OTHERWISE PROVIDED IN THIS DEED OF TRUST OR THE OTHER LOAN DOCUMENTS, AGREES
THAT IF, FOR ANY REASON, A PREPAYMENT OF ALL OR ANY PORTION OF THE PRINCIPAL
AMOUNT OF THE NOTE IS MADE, WHETHER VOLUNTARILY OR UPON OR FOLLOWING ANY
ACCELERATION OF THE MATURITY DATE OF THE NOTE BY BENEFICIARY ON ACCOUNT OF ANY
DEFAULT BY TRUSTOR, INCLUDING, WITHOUT LIMITATION, ANY TRANSFER, DISPOSITION, OR
FURTHER ENCUMBRANCE PROHIBITED OR RESTRICTED BY THIS DEED OF TRUST, THEN TRUSTOR
SHALL BE OBLIGATED TO PAY 


                                       73
<PAGE>   79

CONCURRENTLY WITH SUCH PREPAYMENT THE PREPAYMENT PREMIUM SPECIFIED IN THE NOTE.
BY INITIALING THIS PROVISION IN THE SPACE PROVIDED BELOW, TRUSTOR HEREBY
DECLARES THAT BENEFICIARY'S AGREEMENT TO MAKE THE LOAN SECURED BY THIS DEED OF
TRUST AT THE INTEREST RATE AND FOR THE TERM SET FORTH IN THE NOTE CONSTITUTES
ADEQUATE CONSIDERATION, GIVEN INDIVIDUAL WEIGHT BY TRUSTOR, FOR THIS WAIVER AND
AGREEMENT.

Trustor's Initials:___________

               (d) The Note further provides that, upon default in the payment
of any installment of principal and interest as and when due thereunder, or upon
default in the performance of or compliance with any of the other covenants or
conditions of any of the Loan Documents, both continuing beyond any time
provided in the Note for the curing of such defaults, then, or at any time
thereafter, Beneficiary may, at its option and without notice, declare the
entire debt then remaining unpaid (including accrued interest and Late Charges
thereunder and any Advances made by Beneficiary under any Loan Documents) to be
immediately due and payable, plus the amount of the Prepayment Premium described
in the Note, and Beneficiary may include the amount of such Prepayment Premium
in any Beneficiary's statement, in any demand for (or answer to any request for
the amount of) full payment and in any bid at a judicial foreclosure or
trustee's sale under this Deed of Trust. Additionally, upon the occurrence of
any default(s), continuing beyond any time provided in the Note for the curing
of such default(s), Beneficiary shall have and may exercise immediately and
without notice any and all rights and remedies available at law or in equity and
also all rights and remedies provided for in any of the Loan Documents.

        3. To the extent permitted by law, during any sale conducted by Trustee
pursuant to the power of sale contained in this Deed of Trust, Beneficiary may,
at Beneficiary's option, direct the Trustee to sell the Mortgaged Property
either as a whole or in separate parcels and in such order as Beneficiary may
determine.

        THIS ASSIGNMENT is made on the following covenants, terms and
conditions:

SECTION 1. BORROWER'S COVENANTS AND WARRANTIES

        Borrower hereby covenants and warrants to Lender as follows:

        (a) Borrower has not executed any prior assignment of any of the Leases
        or Rents which will remain effective after the recording of this
        Assignment, nor has it performed any act or executed any other
        instrument which might prevent Borrower from fulfilling any of the terms
        and conditions of this Assignment or which might prevent Lender from
        operating under any of the terms and conditions of this Assignment or
        which would limit Lender in such operation;

        (b) Borrower has not executed or granted any modification whatsoever of
        any of the Leases, except as delivered to Lender; the Leases are in full
        force and effect; and, except as disclosed to the Lender on a rent roll
        delivered to Lender concurrently herewith, there are no material
        defaults now existing under any of the Leases, or any conditions which,
        after notice, passage of time, or both would constitute material
        defaults;

        (c) Borrower will observe and perform all the obligations imposed upon
        the lessor under each of the Leases;

        (d) Borrower will not collect any of the rents, issues, income, proceeds
        and profits arising or accruing under the Leases or from the Premises
        more than 1 month in advance of the time when the same shall become due
        under the Leases (except customary security deposits) nor execute any
        other assignment of the Leases or assignment of rents, issues, income,
        proceeds or profits with respect to the Premises; and

        (e) Except as permitted pursuant to the Mortgage, Borrower will not
        alter or modify the terms of the Leases, give any consent or exercise
        any option required or permitted by such terms, accept a surrender
        thereof, or consent to any assignment of or subletting under any of the
        Leases, whether or not in accordance with their terms.


                                      -2-
<PAGE>   3







 SECTION 2.      ABSOLUTE ASSIGNMENT OF LEASE(S)

        Borrower and Lender intend that this Assignment constitute a present,
 irrevocable and absolute assignment of the Leases and Rents, and not an
 assignment for additional security only. Subject to the terms of this Section
 2, Lender grants to Borrower a revocable license ("LICENSE") to collect and
 receive the Rents. Borrower hereby agrees that Lender may authorize direct the
 lessees named in the Leases, and any other occupants of the Premises, and all
 Lease guarantors, to pay over to Lender or such other party as Lender may
 direct, all Rents, upon receipt from Lender of written notice to the effect
 that an Event of Default (defined below) exists, and to continue to do so until
 the lessees are otherwise notified by Lender.

 SECTION 3.      REVOCATION OF LICENSE

        Upon or at any time after the occurrence of an Event of Default as
 defined in the Note or Mortgage which permits acceleration of the Loan
 (collectively, an "EVENT OF Default"), the License granted to Borrower in
 Section 2 of this Assignment shall automatically be revoked without the need of
 any action by Lender, and Lender shall immediately be entitled to receipt and
 possession of all Rents, whether or not Lender enters upon or takes control of
 the Premises.

        Upon demand by Lender after the occurrence of an Event of Default,
 Borrower shall immediately deliver to Lender all Rents in the possession of
 Borrower or its agents, and shall cooperate in instructing Borrower's agents
 and the lessees under the Leases and all others in possession of the Premises
 or any portion thereof to pay directly to Lender all Rents.

        Upon revocation of the License, Lender may, at its option, without
 waiving such Event Default and without notice or regard to the adequacy of the
 security for the Debt, either in person or by agent, nominee or attorney, or by
 a receiver appointed by a court, with or without bringing any action or
 proceeding, dispossess Borrower and its agents and servants from the Premises,
 without liability for trespass, damages or otherwise, and exclude Borrower and
 its agents from the Premises.

        Upon revocation of the License, Lender may also take possession of the
 Premises, and books, records and accounts relating thereto and have, hold,
 manage, lease and operate the Premises on such terms and for such period of
 time as Lender may deem proper. In addition, and with or without taking
 possession of the Premises, Lender, in its own name, may demand, sue or
 otherwise collect and receive all Rents, including those past due and unpaid
 and may apply any Rents collected in such order of priority as Lender in its
 sole discretion deems appropriate, to the payment of:

        (a) all expenses of managing the Premises, including, without
        limitation, the salaries, fees and wages of a managing agent and such
        other persons or entities as Lender may deem necessary or desirable, and
        all expenses of operating and maintaining the Premises, including,
        without limitation, all taxes, claims, assessments, ground rents, water
        rents, sewer rents and any other liens or charges, and premiums for all
        insurance which Lender may deem necessary or desirable, and the cost of
        all alterations, renovations, repairs or replacements, and all expenses
        incident to taking and retaining possession of the Premises;


                                      -3-
<PAGE>   4







        (b)    the Debt; and

        (c) all reasonable costs and attorneys' fees incurred in connection with
        the enforcement of this Assignment and any of the Loan Documents.

 SECTION 4.      NO LIABILITY OF LENDER

        This Assignment shall not be construed to bind Lender to the performance
 of any of the covenants, conditions, or provisions contained in any Lease, or
 otherwise impose any obligation upon Lender. Lender shall not be liable for any
 loss sustained by Borrower resulting from Lender's failure to let the Premises
 after an Event of Default, or from any other act or omission of Lender either
 in collecting the Rents, or if Lender shall have taken possession of the
 Premises, in managing the Premises after an Event of Default, unless such loss
 is caused by the gross negligence or willful misconduct of Lender.

 SECTION 5.      NO MORTGAGEE IN POSSESSION

        In the absence of taking of actual possession of the Premises by Lender,
 in its own right and person, Lender (i) shall not be deemed a mortgagee in
 possession, (ii) shall not be responsible for the payment of any taxes or
 assessments with respect to the Premises, (iii) shall not be liable to perform
 any obligation of the lessor under any of the Leases or under applicable law,
 (iv) shall not be liable to any person for any dangerous or defective condition
 in the Premises nor for any negligence in the management, upkeep, repair, or
 control of the said Premises resulting in loss or injury or death to any
 person, and (v) shall not be liable in any manner for the remediation of any
 environmental impairment.

 SECTION 6.      BANKRUPTCY

        After the occurrence of an Event of Default which permits acceleration
 of the Loan, Lender shall have the right to proceed in its own name or in the
 name of Borrower in respect of any claim, suit, action or proceeding, relating
 to any of the Leases in a proceeding under the bankruptcy laws of the United
 States ("Bankruptcy Code") including, without limitation, the right to file and
 prosecute, all to the exclusion of Borrower, any proofs of claim, complaints,
 motions, applications, notices and other documents.

 If there shall be filed by or against Borrower a petition under the Bankruptcy
 Code, and Borrower, as lessor under the Leases, shall determine to reject any
 Leases pursuant to Section 365(a) of the Bankruptcy Code, the Borrower shall
 give Lender not less than ten (10) days' prior notice of the date on which
 Borrower shall apply to the bankruptcy court for authority to reject the
 Leases. Lender shall have the right, but not the obligation, to serve upon
 Borrower within such ten-day period a notice stating that (i) Lender demands
 that Borrower assume and assign the Lease to Lender pursuant to Section 365 of
 the Bankruptcy Code and (ii) Lender covenants to cure or provide adequate
 assurance of future performance under the Leases. If Lender serves upon
 Borrower the notice described in the preceding sentence, Borrower shall not
 seek to reject the Leases and shall comply with the demand provided for in
 clause (i) of the preceding sentence within thirty (30) days after the notice
 shall have been given, subject to the performance by Lender of the covenant
 provided for in clause (ii) of the preceding sentence.


                                      -4-
<PAGE>   5







 SECTION 7.      INDEMNITY OF LENDER

        Borrower hereby indemnifies Lender for, and holds Lender harmless from,
any and all liability, loss or damage which may be incurred under said Leases,
or under or by reason of this Assignment, and from any and all claims and
demands whatsoever which may be asserted against Lender by reason of any alleged
obligations or undertakings under any of the Leases, except any claims arising
out of Lender's gross negligence or will misconduct.

        Should Lender incur any such liability under the Leases or under or by
reason of this Assignment or in defense of any such claims or demands, the
amount thereof, including costs, expenses and reasonable attorneys' fees, shall
be secured by the Mortgage and Borrower shall reimburse Lender therefor,
immediately upon demand and upon the failure of Borrower so to Lender, at its
option, may declare all sums secured by the Mortgage immediately due and
payable.

 SECTION 8.      NO WAIVER OF RIGHTS BY LENDER

        Nothing contained in this Assignment and no act done or omitted by
Lender pursuant to powers and rights granted it hereunder shall be deemed to be
a waiver by Lender of any of its rights and remedies under the Note, Mortgage or
any other instrument securing the Note. This Assignment is made and accepted
without prejudice to any of such rights and remedies possessed by Lender to
collect the Debt and to enforce the Loan Documents, and said rights and remedies
may be exercised by Lender either prior to, simultaneously with, or subsequent
to any action taken by it hereunder.

 SECTION 9.      RELEASES OF PARTIES AND SECURITY

        Lender may take or release other security for the payment of the Debt,
may release any party primarily or secondarily liable therefor, and may apply
any other security held by it to the satisfaction of any portion of the Debt
without prejudice to any of its rights under this Assignment.

 SECTION 10.     FUTURE ASSURANCES

        Borrower agrees that it will, from time to time, upon demand therefor by
Lender, deliver to Lender an executed counterpart of each of the Leases.
Further, Borrower agrees that it will execute, acknowledge and record such
additional assurances and assignments as Lender may request covering any and all
of the Leases. Such assignments shall be on forms approved by the Lender, and
Borrower agrees to pay all costs incurred in connection with the examination of
the Leases and the preparation, execution and recording of such assignments or
any other related documents, including, without limitation, fees of Lender's
local counsel.

 SECTION 11.     AMENDMENTS

        This Assignment may not be altered or amended except in a writing,
intended for that specific purpose, signed by both Borrower and Lender.

                      SUBORDINATION OF MANAGEMENT AGREEMENT


               This Agreement is made and entered into as of the 30th day of
March, 1999, by ARDEN REALTY FINANCE V, L.L.C., a Delaware limited liability
company ("Owner"), and ARDEN REALTY LIMITED PARTNERSHIP a Maryland limited
partnership ("Manager"), in favor of MASSACHUSETTS MUTUAL LIFE INSURANCE
COMPANY, a Massachusetts corporation ("Lender"), with reference to the
Management Agreement and Properties as hereinafter defined.

               Manager manages each of those certain real properties located in
the State of California, more particularly described on Exhibit "A" hereto
(collectively, referred to as the "Properties"), pursuant to that certain
Property Management Agreement (the "Management Agreement") dated March 31, 1999,
executed by Owner and Manager, a copy of which Management Agreement is attached
hereto as Exhibit "B".

               In order to induce Lender to close a permanent loan with respect
to the Properties, Manager desires to subordinate all of Manager's rights and
interests under the Management Agreement to the rights and interests of Lender
under the documents evidencing and securing the said loan ("Loan Documents") and
to make the agreements for the benefit of Lender hereinafter set forth; and
Owner desires to consent to the agreements of Manager set forth in this
Agreement and to enter into certain agreements, hereinafter set forth, for the
benefit of Lender.

               NOW THEREFORE for good and valuable consideration, the receipt
and sufficiency of which are hereby acknowledged, the parties agree as follows:

               1. The Owner and Manager agree not to materially alter or amend
the terms of the Management Agreement or otherwise delegate or assign to others
the management of the Properties without the prior written consent of Lender.

               2. Manager hereby acknowledges and agrees that its rights
(including without limitation rights to payment) and interests, if any, in the
Properties pursuant to the Management Agreement, or otherwise, are and shall be
in all respects inferior, subject, and subordinate to the rights and interest of
Lender pursuant to the Loan Documents. If Manager receives any management fees
after its receipt of written notice from Lender that an Event of Default, as
defined in the Loan Documents, has occurred, and after any applicable notice and
cure periods, such sums shall be paid by Manager to Lender upon demand.


                                      -1-
<PAGE>   2





               3. Should an Event of Default occur under any of the Loan
Documents and should Lender elect to exercise its rights and remedies under the
Loan Documents, the Management Agreement and Manager's rights, interests, and
entitlement thereunder, at the option of Lender, may be terminated by Lender
effective upon Lender's providing Manager with written notice of its election to
so terminate the Management Agreement.

               4. In the event of termination of the Management Agreement
pursuant to paragraph 3 above, Manager agrees to deliver, or make available to
Lender during normal business hours, all leases, books, records, accounts,
deposits, brochures and all other information and property in Manager's
possession regarding the management and operation of the Properties.

               5. Exercise of the rights of Lender hereunder shall be without
any liability of Lender to Manager for past due management fees, expenses,
termination fees or otherwise for any sums owed by Owner to Manager pursuant to
the Management Agreement, provided that should Lender elect to continue to
employ Manager for the operation of the Properties, Lender shall pay Manager for
all fees and expenses accruing from and after the date Lender enters into
possession of the Properties.

               6. All notices to Manager or Lender required or permitted
hereunder shall be given in writing by registered or certified mail, return
receipt requested, or by overnight courier providing a receipt, at the following
addresses,

               8. This Agreement shall be binding upon the successors and
assigns of the parties hereto and shall inure to the benefit of the successors

Agreement may be waived except by an agreement in writing signed by the party
against which the amendment or waiver is asserted and approved in writing by
Lender.

                           AND HOLD HARMLESS AGREEMENT


        THIS ENVIRONMENTAL INDEMNIFICATION AND HOLD HARMLESS AGREEMENT (this

        WHEREAS, Borrower is the owner of certain real properties situated in
the State of California, as more particularly described on Exhibit "A" attached
hereto and made a part hereof (such real properties, together with any
additional real property hereafter encumbered by the lien of the Mortgage (as
defined below), and all improvements now or hereafter located thereon and all
rights and interests of Borrower therein, are hereinafter referred to as the

        WHEREAS, Lender is about to make a loan to Borrower in the original

($115,000,000.00) (the "LOAN") to be evidenced by a Promissory Note of even date

        WHEREAS, the Note will be secured, inter alia, by a Deed of Trust and
Security Agreement of even date herewith, executed by Borrower as trustor,
naming Lender as beneficiary and Chicago Title Insurance Company as trustee,

acknowledged, and intending to be legally bound hereby, Indemnitor hereby

their predecessors in interest, third parties who have trespassed on the Land or
parties in a contractual relationship with Indemnitor, or any of them, or
anybody else whether or not occasioned wholly or in part by any condition,
accident or event caused by any act or omission of Lender unless the same
constitute gross negligence or willful misconduct) which:

        A.      arise out of the actual, alleged or threatened migration,
                spilling, leaching, pouring, emptying, injection, discharge,
                dispersal, release, storage, treatment, generation, disposal or

                reconditioned or reclaimed; or

        B.      Actually or allegedly arise out of the use, specification or

                chemicals, the failure to detect the existence or proportion of
                chemicals, the failure to detect the existence or proportion of
                chemicals in the soil, air, surface water or ground water, or

                pollution source or the replacement or removal of any soil,

part hereof, with the same force and effect as if set forth fully in this

herein shall survive any termination or expiration of the documents evidencing
or securing the Loan and/or the repayment of the indebtedness evidenced by the
Note included but not limited to any foreclosure on the Mortgage or any
deed-in-lieu of foreclosure; it being understood and agreed that the indemnity
given herein is independent of the secured indebtedness and the documents
securing the Loan. Notwithstanding the aforesaid, Indemnitor's indemnification
and representations shall not extend to Hazardous Materials (as defined on
Exhibit "B") which first become present on the Land or any improvements thereon
after Lender's succession to title by virtue of a foreclosure or deed-in-lieu of
foreclosure, or any claims arising out of any gross negligence or willful
misconduct by any indemnified party.
