of September 18, 2001, among Excel Legacy Corporation, a Delaware corporation
(the "Company"), Price Legacy Corporation, a Maryland corporation ("Price
Legacy"), and Wells Fargo Bank Minnesota, N.A. (the "Trustee").

                                    RECITALS

         WHEREAS, the Company and the Trustee entered into an Indenture, dated
as of November 5, 1999 (the "Indenture"), pursuant to which the Company has
originally issued its 9.0% Convertible Redeemable Subordinated Secured
Debentures due November 5, 2004 (the "Securities");

         WHEREAS, Section 9.02 of the Indenture provides that, subject to
certain conditions stated therein, the Company and the Trustee may amend the
Indenture or the Securities with the written consent of the Holders of a
majority in principal amount of the then outstanding Securities (the "Requisite
Consents");

         WHEREAS, the Company deems it desirable to make certain amendments to
the Indenture;

         WHEREAS, the merger of the Company with and into a wholly-owned
subsidiary of Price Legacy (the "Merger") has occurred as of September 18, 2001,
and Price Legacy desires to assume the obligations set forth in Section 10 of
the Indenture, as appropriately adjusted to reflect that each share of common
stock of the Company was converted into 0.6667 of a share of common stock of
Price Legacy in the Merger; and

         WHEREAS, the Company and Price Legacy have determined that all things
necessary to make this Supplemental Indenture a valid indenture and agreement
according to its terms, including without limitation the receipt of the
Requisite Consents, have been done, and the Company has delivered to the Trustee
an Officer's Certificate and Opinion of Counsel stating that all conditions
precedent provided for in the Indenture relating to executing this Supplemental
Indenture have been complied with.

         NOW, THEREFORE, in consideration of the foregoing and for other good
and valuable consideration, the receipt of which is hereby acknowledged, the
parties hereto mutually covenant and agree for the equal and ratable benefit of
the Holders of the Securities as follows:

                  between the Company and the Trustee. The terms of the

                  made part of the Indenture by reference to the Trust Indenture
                  Act of 1939 (15 U.S. Code Sections 77aaa-77bbbb) (the "TIA")
                  as in effect on the date of the Indenture. The Securities are
                  subject to, and qualified by, all such terms, certain of which
                  are summarized hereon, and Securityholders are referred to the
                  Indenture and such Act for a statement of such terms. The
                  Securities are general obligations of the Company limited to
                  $36,599,767 in aggregate principal amount."

                  entirety as follows:

                           " 7. Conversion. A holder of a Security may convert
                  it into Common Stock of the Company at any time before the
                  close of business (New York time) on the day prior to the
                  maturity date. If the Security is called for redemption, the
                  holder may convert it at any time before the close of business
                  (New York time) on the day prior to the redemption date
                  (unless the Company shall default in payment due upon
                  redemption thereof). The conversion price of $8.25 per share
                  is subject to adjustment in certain events. To determine the
                  number of shares issuable upon conversion of a Security,
                  divide the principal amount to be converted by the conversion
                  price in effect on the conversion date. On conversion, no
                  payment or adjustment for interest will be made. However,
                  interest will be paid on any interest payment date with
                  respect to Securities surrendered for conversion after a
                  record date for the payment of interest to the registered
                  holder on such record date. The Company will deliver a check
                  for any fractional share."

         1.8      AMENDMENTS TO EXHIBIT B.  Exhibit B is hereby terminated in
its entirety.
