              NON-RECOURSE PROMISSORY NOTE SECURED BY DEED OF TRUST

$9,375,000.00                                                     April 11, 2001

        FOR VALUE RECEIVED, the undersigned, TC KEARNY VILLA, L.P., a Delaware
limited partnership ("Borrower"), whose address is 4250 Executive Square, Suite
200, La Jolla, California 92037, Attn: Dorcey B. Abshier, promises to pay to
DELTA DESIGN, INC., a Delaware corporation ("Lender"), or order, at 5755 Kearny
Villa Road, San Diego, California 92123, or such other place as Lender may
designate, in lawful money of the United States the principal sum of Nine
Million Three Hundred Seventy-Five Thousand and 00/100 Dollars ($9,375,000.00)
together with interest thereon as provided herein. The outstanding principal
amount of the Loan and interest thereon are payable at the time and in the
manner set forth herein. This Note is secured by a Short Form Deed of Trust and
Assignment of Rents dated of even date herewith executed by Borrower, as
trustor, to Chicago Title Company, as trustee, in favor of Lender, as
beneficiary (the "Deed of Trust"), encumbering that certain real property (the
"Property") more particularly described in the Deed of Trust.

        1. Maturity Date.

                (a) The then outstanding principal amount of this Note, together
with all interest unpaid and accrued thereon, shall be due and payable on the
date that is six (6) months after the date of this Note (the "Original Maturity
Date"). Notwithstanding the foregoing, Borrower shall have the option to extend
the Original Maturity Date for one hundred eighty (180) days by satisfying each
of the following conditions precedent: (i) delivery of written notice to Lender,
at least fifteen (15) days prior to the Original Maturity Date, that Borrower
desires to extend the Original Maturity Date, (ii) payment delivered with the
foregoing notice of an extension fee in the amount of Forty-Six Thousand Eight
Hundred Seventy-Five Dollars ($46,875) which is equal to one half of one percent
(0.5%) of the original principal amount of the Loan; (iii) delivery to Lender of
an endorsement to Lender's title policy obtained in connection with the Loan,
insuring that the priority of the lien of the Deed of Trust will not be impaired
by such extension and (iv) execution of such documents as Lender reasonably
requires to evidence such extension. The term "Maturity Date" as used in this
Note shall mean the Original Maturity Date, unless Borrower timely extends the
Original Maturity Date as provided in this Section 1(a), in which event the
Maturity Date shall mean the Original Maturity Date, as so extended.

                (b) If the Maturity Date shall fall on a day other than a
Business Day (defined below), payment of the outstanding balance of the
principal and accrued interest due under the terms hereof shall be made on the
next succeeding Business Day and such extension of time shall be included in
computing any interest with respect of such payment. As used in this Note,
"Business Day" means a day other than Saturday, Sunday or any Optional Bank
Holiday (as defined in Section 7.1 of the California Civil Code).

                                       1

        2. Payment of Interest.

                (a) Borrower will pay interest only monthly on the then
outstanding principal balance of this Note, commencing May 1, 2001, and
continuing on the first (1st) day of each subsequent month thereafter until the
entire indebtedness evidenced by this Note is fully paid.

                (b) Interest on the outstanding principal amount of the Loan,
shall accrue at eight percent (8%) per annum from and after the date hereof.

        3. Non-Recourse. Notwithstanding anything to the contrary contained in
this Note or the Deed of Trust, (a) this Note is non-recourse as to Borrower,
and (b) Lender's recourse under this Note shall be limited solely to the
Property and Lender waives it right to enforce against Borrower a judgment
imposing liability on Borrower for any deficiency in payment of the indebtedness
evidenced by this Note or in payment of financial obligations under this Note or
the Deed of Trust. Accordingly, neither Borrower nor any of its officers,
directors, shareholders, employees, members, agents or affiliates shall have any
personal liability whatsoever under this Note and no other property or assets of
Borrower or any other person shall be subject to levy, execution or other
enforcement procedure for the satisfaction of Lender's remedies under or with
respect to this Note or the Deed of Trust.

        4. Assignability. Borrower shall not transfer, assign or convey its
rights or obligations under this Note without first obtaining Lender's written
consent which may be withheld in its sole and absolute discretion.
Notwithstanding the foregoing or anything to the contrary contained in this Note
or the Deed of Trust, Borrower may, without obtaining Lender's consent, assign
the Property and its rights and obligations hereunder to an entity affiliated
with Borrower, or to a new entity in which Borrower is a member, partner or
manager, or with who Borrower (or any affiliate thereof) has entered into a
development services agreement, a property management agreement or other
agreement of a similar nature with respect to the Property or any portion
thereof, and Borrower will thereafter be relieved of liability hereunder;
provided that Borrower provides prior written notice of such transfer to Lender,
and the transferee executes a commercially reasonable document whereby
transferee assumes all obligations under this Note and the Deed of Trust.

        5. Default. Borrower shall be in default under this Note, and an "Event
of Default" will have occurred if (i) Borrower defaults in the performance or
observance of any covenants, conditions, provisions or agreements contained in
this Note or the Deed of Trust and fails to cure any such default within twenty
(20) days after written notice thereof given to Borrower by Lender; provided,
however, that if any such default reasonably takes longer than twenty (20) days
to cure, then it shall not be deemed to be an Event of Default if Borrower
commences such cure within said twenty (20) day period and thereafter diligently
prosecutes such cure to completion; or (ii) any amount payable under this Note
is not paid when due, and the Borrower fails to cure such default within three
(3) Business Days after written notice thereof given to Borrower by Lender.

        6. Remedies. Upon the occurrence of an Event of Default and without
demand or notice, Lender shall have the option to declare the entire outstanding
principal balance of the

                                       2
<PAGE>   3

Loan together with all accrued interest thereon immediately due and payable and
to exercise all rights and remedies available to it under this Note and the Deed
of Trust.

        7. Prepayment. Borrower may, at any time in its sole discretion, prepay
the outstanding principal amount of the Loan, either in whole or in part,
without penalty or premium.

        8. No Waiver. No waiver by Lender of any default or breach by Borrower
hereunder shall be implied from any omission by Lender to take action on account
of such default if such default persists or is repeated, and no express waiver
shall affect any default other than the default in the waiver and such waiver
shall be operative only for the time and to the extent therein stated. Waivers
of any covenant, term or condition contained herein shall not be construed as a
waiver of any subsequent breach of the same covenant, term or condition. The
consent or approval by Lender to or of any act by Borrower requiring further
consent or approval shall not be deemed to waive or render unnecessary the
consent or approval to or of any subsequent similar act.

        9. Miscellaneous.

                (a) Notices required or permitted to be given by Borrower to
Lender or Lender to Borrower shall be in writing and shall be effective only if
sent by personal delivery, overnight courier or Untied State certified mail,
return receipt requested, postage prepaid, addressed to Lender at the address
set forth above or to Borrower at the address set forth above. Notices shall be
deemed effective, given and delivered on the date of actual receipt of such
notice, when delivered in the manner designated in this Section 9(a).

                (b) If there is an action by Lender or Borrower based upon the
terms of this Note, the prevailing party shall be entitled to recover the
reasonable attorneys' fees and costs and expenses incurred in prosecuting or
defending such action.

                (c) This Note may not be changed orally, but only by an
agreement in writing signed by the party against whom enforcement is sought.
This Note shall be construed in accordance with and governed by the laws of the
State of California without regard to choice of law.

                (d) This Note shall be binding upon Borrower and its heirs,
representatives, successors and assigns.

                (e) Time is of the essence with respect to the performance of
every provision of this Note.

                (f) Any provision of this Note which shall prove to be invalid,
void, or illegal shall in no way affect, impair or invalidate any other
provision hereof, and any such other provisions shall remain in full force and
effect.

        10. Late Charge. Lender, by accepting this Note, and Borrower agree that
if any payment due hereunder is received by Lender more than three (3) Business
Days after Borrower receives written notice from Lender of Borrower's failure to
make such payment, Borrower will pay to Lender a late charge of five percent
(5%) of such payment so overdue. In connection

                                       3
<PAGE>   4

therewith, Borrower and Lender agree as follows: because of such non-payment,
Lender will incur certain costs and expenses including, but not limited to,
administrative costs, collection costs, and other direct and indirect costs in
an uncertain amount; it would be impractical or extremely difficult to fix the
exact amount of such costs and expenses in such event; such late charge is a
fair and reasonable sum considering all of the circumstances existing on the
date hereof and represents a fair and reasonable estimate of the costs and
expenses which will be sustained by Lender due to the failure of Borrower to
make timely payments; and such late charge will constitute liquidated damages
caused by such non-payment but only to the extent such late charge is paid by
Borrower and accepted by Lender and only upon the condition that any such
default and all other defaults are completely cured concurrently with such
payment.

        11. Default Rate. If any payment due under this Note is not received
within three (3) Business Days after Borrower receives written notice from
Lender of Borrower's failure to make such payment, Lender shall have the right,
without acceleration of the indebtedness evidenced hereby, to collect interest
on such amount then due at a rate per annum equal to the lesser of (i) eight
percent (8%), or (ii) the maximum rate of interest, if any, which may be charged
or collected from Borrower under applicable law. Such interest shall be
immediately due and payable and shall accrue until full payment is received.

        12. Authority. Borrower has or will have the legal power, right and
authority to enter into the Loan, this Note and the Deed of Trust, and to
consummate the transactions contemplated hereby. Borrower represents and
warrants that each individual executing this Note and the Deed of Trust on
behalf of Borrower has or will have the legal power, right and actual authority
to execute this Note and the Deed of Trust and to bind Borrower to the terms and
conditions hereof and thereof.

        13. Interest Rate Limitation. It is the intent of Lender and Borrower in
the execution of this Note and all other instruments securing this Note that the
Loan evidenced hereby be exempt from the restrictions of the usury laws of the
State of California. In the event that, for any reason, it should be determined
that California usury law is applicable to the Loan, Lender and Borrower
stipulate and agree that none of the terms and provisions contained herein or in
the Deed of Trust shall ever be construed to create a contract for the use,
forbearance or detention of money requiring payment of interest at a rate in
excess of the interest rate permitted to be charged by the laws of the State of
California. In such event, if Lender shall collect monies which are deemed to
constitute interest which would otherwise increase the effective interest rate
on this Note to a rate in excess of the rate permitted to be charged by the laws
of the State of

                                       4
<PAGE>   5

California, all such sums shall, at the option of Lender, be credited to the
payment of the sums due hereunder or returned to Borrower.
