                              WAIVER AND AMENDMENT

                               TO CREDIT AGREEMENT

            THIS WAIVER AND AMENDMENT TO CREDIT AGREEMENT (the "Amendment") is
made and entered into as of September 25, 1998, among NEW PLAN REALTY TRUST, a
Massachusetts business trust, ("New Plan" or the "Borrower"), THE BANK OF NEW
YORK, as agent for the Lenders (the "Agent"), and the financial institutions
listed on the signature pages hereto.

                                    RECITALS:

      A. The Borrower, the Agent and certain financial institutions entered into
that certain Credit Agreement dated as of November 21, 1997 (as amended, the
"Credit Agreement"; defined terms used in this Amendment which are not otherwise
defined herein shall have the meaning ascribed to such terms in the Credit
Agreement).

      B. The Borrower has entered into that certain Agreement and Plan of Merger
among the Borrower, Excel Realty Trust, Inc. ("Excel"), and ERT Merger Sub, Inc.
("Merger Sub"), dated May 14, 1998, as amended by that certain Amendment to
Agreement and Plan of Merger, dated as of August 7, 1998, among the Borrower,
Excel and the Merger Sub (collectively, the "Merger Agreement").

      C. In accordance with the Merger Agreement, at the Effective Time under
and as defined in the Merger Agreement (the "Effective Time") (i) shares of
beneficial interest of New Plan will be converted into the right to receive
common shares of the stock of the Combined Company (hereinafter defined), (ii)
the Merger Sub will be merged with and into New Plan with New Plan surviving as
a wholly owned subsidiary of Excel, (iii) Excel will change its name to "New

Time, the "Combined Company") and (iv) the merger contemplated by the Merger
Agreement (the "Merger") will be consummated by filing the appropriate articles
of merger and certificate of amendment and merger with the appropriate
authorities in the State of Maryland and Commonwealth of Massachusetts, all as
more particularly described in the Merger Agreement and the Proxy Statement
(hereinafter defined).

      D. The Borrower and Excel have called meetings of their respective
shareholders to be held on September 25, 1998 to approve the Merger and other

(the "Proxy Statement"). If approved, the Borrower contemplates that the
Effective Time will occur prior to October 1, 1998.

      E. The Borrower's consummating the Merger and the other transactions
contemplated by the Merger Agreement and the Proxy Statement will constitute an

Agreement. The Borrower has requested that as of the Effective Time the Agent
and the Lenders (i) waive the Event of Defaults occurring by reason of the

the terms of this Amendment.

mutual agreements contained herein, and for other good and valuable
consideration, the receipt of which is hereby acknowledged, the parties hereto

Time, any Event of Default under Section 8.2, 8.5, 8.7 or Section 9.1(o) of the
Credit Agreement occurring by reason of the consummation of the Merger in
accordance with the Merger Agreement and the Proxy Statement (each a "Merger
Default" and collectively, the "Merger Defaults").

      2. Amended Definitions. As of the Effective Time, Section 1.1 of the
Credit Agreement ("Definitions") shall be deemed amended by deleting therefrom

in its place. Accordingly, as of the Effective Time, the "Threshold Amount"

      5. Representations. The parties acknowledge that as of the Effective Time,
Schedules 4.1, 4.5, 4.12, 8.3 and 8.4 will be revised and replaced pursuant to
the terms of the Assumption and Substitution Agreement attached hereto as
Attachment 1, and such replacement shall effectively amend the Sections of the
Credit Agreement corresponding to such Schedules. In addition, as of the
Effective Time, the following new Section 4.21 shall be deemed added to the
Credit Agreement at the end of Article 4 of the Credit Agreement:

            4.21  BankBoston Credit Agreement.

                  No Event of Default exists under and as defined in the
            BankBoston Credit Agreement.

      6. Financial Statements. As of the Effective Time, Section 4.13 of the

                  The Borrower has heretofore delivered to the Agent and the
            Lenders the selected historical consolidated financial information
            of New Plan and Excel and the pro-forma operating and financial
            information, balance sheets, statements of income and other
            financial information with respect to New Plan, Excel and the
            Borrower set forth in the Proxy Statement (the "Financial
            Statements"). The Financial Statements fairly present the
            Consolidated financial condition of the Borrower and its
            Subsidiaries as of the date of said financial statements and were
            true and correct in all material respects as of such date. Since the
            date of the Financial Statements, the Borrower and each Subsidiary
            has conducted its business only in the ordinary course and there has
            been no Material Adverse Change.

      7. Legal Existence. As of the Effective Time, Section 7.3 of the Credit
Agreement shall be deemed deleted and the following new Section 7.3 shall be

            Adverse Effect.


                                       4
   5


      8. Declaration of Trust. As of the Effective Time, all references to the
"Declaration of Trust" in the Credit Agreement shall be deemed to refer,
collectively, to the Charter and By-Laws of the Combined Company as they exist
at such time. In furtherance of the foregoing, Section 8.7 of the Credit
Agreement ("Declaration of Trust") shall be deemed deleted and the following new
Section 8.7 shall be inserted in its place:

            8.7 Charter and By-Laws.

                  Amend or otherwise modify its Charter or By-Laws in any way
            (other than in connection with the issuance or classification of
            preferred stock of the Borrower) which would adversely affect the
            interests of the Agent and the Lenders under any of the Loan
            Documents, or permit any Subsidiary to amend its organizational
            documents in a manner which could have the same result.

      9. Certain Prepayments. As of the Effective Time, Section 8.9 shall be
deemed amended to add the following sentence at the end thereof:

Section 8.13 in its entirety and substitute in its place the following new
Section 8.13:

            8.13  Issuance of Additional Capital Stock by Subsidiaries.

                  Permit any Subsidiary to issue any additional Stock or other
            equity interest of such Subsidiary, other than the issuance of
            partnership units in down-REIT partnership Subsidiaries of the
            Borrower, provided that such partnership units are issued (i) in the
            normal course of the Borrower's business and (ii) in consideration
            of the contribution to the down-REIT partnership of assets
            qualifying as "real estate assets" under Section 856(c) of the Code.

      11. Minimum Tangible Net Worth. As of the Effective Time, Section 8.15 of
the Credit Agreement shall be deemed amended to delete the number

            its Subsidiaries, determined on a Consolidated basis, as determined
            in accordance with GAAP, at any time to be more than 50% of Total
            Capital at such time, or (ii) the indebtedness of the Borrower and
            its Subsidiaries, determined on a Consolidated basis, secured by
            mortgages on Real Property owned by the Borrower and its
            Subsidiaries at any time to exceed 40% of Total Capital at such
