referred to as a "Presentment Event." Borrower expressly covenants and agrees
that Lender has the unconditional right to present the Letter of Credit upon the
occurrence of a Presentment Event, by clean sight draft and without other
documentation, certification or statement. Any failure or delay of Lender to
present the Letter of Credit shall not act as a waiver of Lender's right to do

of Credit (the "Proceeds"), Lender shall apply such Proceeds, at its option,

Letter of Credit, regardless of whether any dispute exists between Borrower and
Lender as to Lender's right to present the Letter of Credit; provided, however,
that such agreement shall not be a waiver of any other right or claim Borrower
may have against Lender. Borrower shall be liable to Lender for any loss, cost
or expense suffered by Lender as a result of such interference, including,
without limitation, any reasonable attorneys' and paralegals' fees and costs.
Without limiting the duty to return the Letter of Credit as set forth in Section
2 hereof, no condition or term of this Agreement shall be deemed to render the
Letter of Credit conditional upon this Agreement or to justify the issuer of any
Letter of Credit in failing to honor a draw upon the Letter of Credit in a
timely manner.

that it is intended that the Letter of Credit is given as security for the

         property, rights, interests and estates now or in the future owned or
         held by Borrower (the "Assigned Property"), for Lender's uses and
         purposes as set forth in this Assignment, subject to the license
         granted by Lender to Borrower in this Assignment to collect and receive
         the Rents until the occurrence and during the continuance of an Event
         of Default:

         6. Notwithstanding that Borrower did not grant a first Lien in the
Expansion Parcel in favor of Lender when the Subsequent Disbursement was made
and advanced to Borrower by Lender, Section 3.2 of the Loan Agreement shall
remain in full force and effect subject to the following:

          (a) If that certain Lender-approved lot line adjustment (the "Lot Line
Adjustment"), adjusting the boundary between the Partial Release Property and
the Expansion Parcel, occurs before September 30, 2002:

                   (i) Borrower agrees that it, and its wholly-owned
subsidiaries, as applicable, shall then forthwith upon completion of the Lot
Line Adjustment grant a first Lien in the Expansion Parcel in favor of Lender
upon the terms and conditions of the Loan Documents including the Mortgage, the
Assignment, and the UCC-1 Financing Statement for the Partial Release Property,
which shall be amended to include the Expansion Parcel as part of the
"Property," "Land," and "Collateral," as applicable.

                   (ii) In addition, with respect to the Expansion Parcel, (A)
Borrower shall satisfy all the conditions and requirements for a Substitution
Property and a Substitution as set forth in Subsections 3.3(f),(g),(h),(i),(k),
and (l) of the Loan Agreement to the sole satisfaction of Lender, and (B) the
owners of all right, title and interest in the Partial Release Property shall
also be the owners of all right, title and interest in the Expansion Parcel with
identical interests thereto. Borrower's obligations pursuant to this Section
6(a)(ii) shall not affect the number of Borrower's permitted Substitutions
pursuant to Section 3.3 of the Loan Agreement.

                   (iii) When the Option Tenant's expansion rights with respect
to the Expansion Parcel lapse, and provided that the Option Tenant has not
exercised such rights, Lender will, upon Borrower's written request, and at
Borrower's sole cost, release its Lien in the Expansion

Parcel, provided that Borrower shall satisfy all the conditions and requirements
set forth in Section 3.2 of the Loan Agreement to the sole satisfaction of
Lender.

          (b) If the Lot Line Adjustment has not occurred before September 30,
2002:

                   (i) Borrower agrees that it, and its wholly-owned
subsidiaries, as applicable, shall then forthwith grant a first Lien in that
certain parcel of land that includes the Expansion Parcel, as described in
Schedule II to this Amendment (the "Pre-adjustment Expansion Parcel"), in favor
of Lender upon the terms and conditions of the Loan Documents including the
Mortgage, the Assignment, and the UCC-1 Financing Statement for the Partial
Release Property, which shall be amended to include the Pre-adjustment Expansion
Parcel as part of the "Property," "Land," and "Collateral," as applicable.

                   (ii) In addition, with respect to the Pre-adjustment
Expansion Parcel, (A) Borrower shall satisfy all the conditions and requirements
for a Substitution Property and a Substitution as set forth in Subsections
3.3(f),(g),(h),(i),(k), and (l) of the Loan Agreement to the sole satisfaction
of Lender, and (B) the owners of all right, title and interest in the Partial
Release Property shall also be the owners of all right, title and interest in
the Pre-adjustment Expansion Parcel with identical interests thereto. Borrower's
obligations pursuant to this Section 6(b)(ii) shall not affect the number of
Borrower's permitted Substitutions pursuant to Section 3.3 of the Loan
Agreement.

                  (iii) Borrower shall use its best efforts to cause the Lot
Line Adjustment to be completed within a reasonable period of time.

                  (iv) When the Lot Line Adjustment occurs, Lender and Borrower
agree that Lender shall release its Lien of the Mortgage on the portion of the
Pre-adjustment Expansion Parcel that does not include the Expansion Parcel,
provided that, with respect to that portion of the Pre-adjustment Expansion
Parcel, Borrower shall satisfy all the conditions and requirements for a Release
Property and a Release as set forth in Subsections 3.1(b), (c), (d), (e), (f),
(g), (h), and (i) of the Loan Agreement to the sole satisfaction of Lender.
Borrower's obligations pursuant to this Section 6(b)(iv) shall not affect the
number of Borrower's permitted Substitutions pursuant to Section 3.3 of the Loan
Agreement.

                  (v) When the Option Tenant's expansion rights with respect to
the Expansion Parcel lapse, and provided that the Option Tenant has not
exercised such rights, Lender will, upon Borrower's written request, and at
Borrower's sole cost, release its Lien in the Expansion Parcel (or, if the Lot
Line Adjustment has not occurred, the Pre-adjustment Expansion Parcel), provided
that Borrower shall satisfy all the conditions and requirements set forth in
Section 3.2 of the Loan Agreement to the sole satisfaction of Lender.

         (c) If the Lot Line Adjustment has not been completed by August 15,
2002, Lender may thereafter incur costs, including, but not limited to, third
party reports, reasonable attorneys' fees, title, survey, engineering and
environmental costs and charges at Borrower's sole expense and otherwise conduct
its due diligence with respect to the Pre-adjustment Expansion Parcel. Borrower
shall use its best efforts to assist Lender to conduct its due diligence with
respect to the Pre-adjustment Expansion Parcel, which shall include, without
limitation, commissioning third

party reports if requested by Lender. This Subsection 6(c) shall not supercede
Borrower's obligation to grant a first Lien in the Expansion Parcel, or the
Pre-adjustment Expansion Parcel, as applicable, upon the provisions of, and
according to the dates specified in, Subsections 6(a) and (b) above.

         (d) In the event that Lender conducts due diligence with respect to the
Pre-adjustment Expansion Parcel, and if that due diligence is not satisfactory
to Lender, as determined by Lender in its sole discretion, Lender may: (i)
delay, without waiving, Borrower's obligation to grant a first Lien in the
Pre-adjustment Expansion Parcel to Lender until Lender is satisfied with its due
diligence or until Borrower has completed the Lot Line Adjustment and has
granted a first Lien in the Expansion Parcel to Lender upon the provisions of
Subsections 6(a) or 6(b) above, or (ii) if for any reason Lender has not been
granted a first Lien in the Expansion Parcel to Lender upon the provisions of
Subsections 6(a) or 6(b) above before December 31, 2003, require Borrower to
exercise a Substitution of the Partial Release Property pursuant to the
provisions of Section 3.3 of the Loan Agreement.

         7. The provisions of the Loan Agreement and this Amendment shall
together constitute and be construed as one document. Any reference to the Loan
Agreement in any other document shall mean the Loan Agreement and this
Amendment, together constituted and construed as one document. Nothing herein
shall be deemed or construed to be an impairment of the lien of the Mortgages.
Except as amended hereby, the Loan Agreement and the Loan Documents remain in
full force and effect.

         8. This Amendment shall be construed under and governed by the Laws of
the State of California.

         9. Defined terms herein shall have the meaning set forth in the Loan
Agreement unless otherwise defined.

         10. Duplicate counterparts of this Amendment may be executed and
together will constitute a single original document.
