         Release Property (including the WAMU Expansion Parcel), and, that, to
         the extent necessary to comply therewith, the transferee, if any, has
         assumed all of Borrower's obligations relating to the WAMU Expansion
         Parcel thereunder;

                                            (v) Borrower shall have delivered to

         shall be no change in the priority of the Lien of the Mortgages or in

         confirm that the WAMU Remainder Partial Release Property constitutes a
         separate legal parcel and a separate tax lot (subject to the provisions
         of item (xi) below);

                                            (vi) not less than ten (10) days
         prior to the date of the WAMU Partial Release, Borrower shall have
         delivered to Lender any consents to the WAMU Partial Release required
         by entities (A) holding Liens affecting the WAMU Partial Release
         Property or holding any other interest in the WAMU Partial Release
         Property as required by documents granting any lien or (B) that would
         otherwise be negatively affected by the WAMU Partial Release, including
         parties to any secondary financing, Property Documents or to any
         Leases;

         to Lender a fully executed amendment satisfactory to Lender to each
         reciprocal easement agreement affecting the WAMU Remainder Partial
         Release Property that joins the transferee, if any, of the WAMU
         Expansion Parcel as a party to each agreement and that provides for any
         additional easements, restrictions and payment obligations that Lender
         deems reasonably necessary for the continued operation and maintenance
         of the WAMU Remainder Partial Release Property;

                                            (ix) Borrower shall have delivered
         to Lender evidence satisfactory to Lender that after the WAMU Partial

         WAMU Remainder Partial Release Property as required by the Loan
         Documents;

                                            (xi) Borrower shall have delivered
         to Lender any other information, approvals and documents reasonably

         without limitation, if the separate tax lot endorsement required in
         item (v) above cannot be obtained, (A) evidence reasonably satisfactory
         to Lender that separate tax lots for the WAMU Remainder Partial Release
         Property and for the WAMU Expansion Parcel will be created by the
         taxing authority within a reasonable period of time after the WAMU
         Partial Release, and (B) an escrow for Taxes, upon provisions
         satisfactory to Lender, for the entire WAMU Remainder Partial Release

and/or rights of first offer (collectively, the "WAMU's Options") granted to
WAMU by Borrower pursuant to the terms and conditions of the WAMU Lease,
Borrower must exercise and complete a Release or a Substitution of the entire
WAMU Partial Release Property, which Release or Substitution shall be completed

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.

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

               B.  Borrower and Lender have agreed to modify the terms and
conditions of the Loan Agreement to, among other things: (i) amend the

Substitutions, and Borrower and Lender are entering into this Second Amendment

                                   AGREEMENT:

the covenants, agreements, representations and warranties set forth in this
Second Amendment and the other Loan Documents, the parties hereto hereby
covenant, agree, represent and warrant as follows:

          1.   Section 1.1 of the Loan Agreement is hereby modified as follows:

         (a)   By adding:

               "`ConAgra Loan' shall mean that certain loan made by Lender
and accepted by Borrower in the principal amount of $12,520,000.00."

         (b)   By deleting the existing definition of Pool A Application in its

                  "`Pool A Application' shall mean that certain Loan Application
and Commitment Agreement, dated March 5, 2002, between Borrower and Lender, as
amended by that certain Loan Application and Commitment Agreement Amendment,
dated June 15, 2002."

         (d)   By deleting the existing definition of Third Disbursement Closing
Date in its entirety and replacing it with the following:

               "`Third Disbursement Closing Date' shall mean on or before
November 15, 2002."

         2.    The introductory paragraph of Section 3.3 of the Loan Agreement
is hereby deleted in its entirety and replaced with the following:

               "After May 1, 2004, not more than twice in a calendar year,
         and not more than an aggregate of five (5) times during the term of the
         Loan (total for this Loan, for substitutions under the Pool A Loan, and
         for substitutions under the ConAgra Loan), Borrower shall have the
         right to grant a Lien in favor of Lender (and add an "Individual
         Property" under the Loan Documents) encumbering certain of Borrower's
         properties (other than a then existing Individual Property) (the
         "Substitution Property") and obtain a release of an Individual Property
         (the "Substituted Property," and collectively, along with the
         Substitution Property, the "Substitution Properties") from the Lien of
         the Mortgage thereon and from Borrower's obligations under the Loan
         Documents (other than those expressly stated to survive) with respect
         to such Substituted Property (collectively, a "Substitution"), subject
         to satisfaction of the following to the sole satisfaction of Lender:"

         3.    Section 3.3(a) of the Loan Agreement is hereby deleted in its
entirety and replaced with the following:

               "each Substitution shall consist of not more than five (5) then
         existing Individual Properties, and all Substitutions, in the
         aggregate, shall consist of not more than fifteen (15) Individual
         Properties (including substituted properties under the Loan (as
         defined herein), substituted properties under the Pool A Loan and
         substituted properties under the ConAgra Loan);"

         4.    The provisions of the Loan Agreement and this Second 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
Second 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.

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

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

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

         IN WITNESS WHEREOF, the parties hereto have caused this Second
Amendment to be duly executed by their duly authorized representatives, all as
