                               FIRST AMENDMENT TO
                               ADVISORY AGREEMENT


          THIS FIRST AMENDMENT TO ADVISORY AGREEMENT is made as of May 21,
1997, by and between WESTFIELD AMERICA, INC., a Missouri corporation (formerly
known as CenterMark Properties, Inc.) ("Owner"), and WESTFIELD U.S. ADVISORY,
L.P., a Delaware limited partnership ("Advisor").

                              W I T N E S S E T H: 


          WHEREAS, Owner and Advisor are parties to that certain Advisory
Agreement (the "Original Advisory Agreement"), dated as of July 1, 1996; and

          WHEREAS, Owner and Advisor desire to amend the Original Advisory
Agreement in the manner hereinafter set forth.

          NOW, THEREFORE, for good and valuable consideration, the receipt and
sufficiency of which is hereby acknowledged, Owner and Advisor agree as follows:

          1.  DEFINITIONS.  All capitalized terms used herein without definition
shall have the respective meanings set forth in the Original Advisory Agreement.

          2.  AMENDMENT TO SECTION 3.1.  Section 3.1 of the Original Advisory
Agreement is hereby amended by deleting such section in its entirety and
substituting the following therefor:

               "3.1.  ADVISORY FEE:

                    The Owner shall pay to the Advisor an annual Advisory
               Fee equal to the lesser of (a) .55% of the Net Equity Value
               of the Owner for such annual period, or (b)  25% of the
               annual "Funds from Operations" (as hereinafter defined) in
               excess of the "Advisory FFO Amount" (as hereinafter
               defined).  The Advisory Fee shall be paid in U.S. Dollars
               and shall be payable quarterly in arrears at the end of each
               calender quarter based on the budgeted annual Advisory Fee
               for the then calender year, subject to final adjustment
               within 90 days after the end of each calender year.  The
               Advisory Fee shall not be payable for the period through
               December 31, 1997.  The first payment on account of the
               Advisory Fee shall be made on March 31, 1998 for the
               quarterly period from January 1, 1998 through March 31,
               1998.   

                    "Funds from Operations" means net income (loss) (computed in
               accordance with generally accepted accounting 


<PAGE>


               principles ("GAAP")) excluding gains (or losses) from debt 
               restructuring and sales of property, plus real estate related 
               depreciation and amortization and after adjustments for 
               consolidated partnerships and joint ventures.  Additionally, 
               leasing commissions which are capitalized in accordance with 
               GAAP are subtracted. Funds from Operations shall be calculated 
               before payment of or deduction for the Advisory Fee.

                    "Advisory FFO Amount" means, as of the date hereof,
               $111,456,090 which amount shall be subject to adjustment
               whenever the Owner issues additional common stock so as to be
               equal to the sum of the then applicable Advisory FFO Amount and
               the "FFO Adjustment Factor" (as hereinafter defined).  The FFO
               Adjustment Factor shall be equal to 103% (except that 100% shall
               be used with respect to common stock issued under the Owner's
               dividend reinvestment plan) multiplied by (a) a fraction the
               numerator of which is the aggregate "Funds from Operations
               Available for Common Stock" (as hereinafter defined) of the Owner
               for each of the four full calendar quarters immediately preceding
               the date of the new issuance and the denominator of which is the
               aggregate number of shares of common stock (on a fully diluted
               basis as required by GAAP) of the Owner then outstanding
               immediately prior to the date of the new issuance multiplied by
               (b) the number of shares of common stock issued in the new
               issuance (on a fully diluted basis as required by GAAP).  "Funds
               From Operations Available for Common Stock" means Funds from
               Operations less (i) the Advisory Fee payable for the applicable
               four full calendar period, and (ii) dividends paid or accrued on
               the Owner's preferred shares during the applicable four full
               calendar quarter period."

          3.  AMENDMENT TO SECTION 3.3.  Section 3.3 of the Original Advisory
Agreement is hereby amended by (i) deleting the period at the end of Section
3.3(b) and substituting "; and" therefor and (ii) inserting the following as
new subparagraph (c):

               "(c)  all costs of preparing and filing required reports with the
               Securities and Exchange Commission, the costs payable by the
               Owner to any transfer agent and registrar in connection with the
               listing and trading of the Owner's stock on the New York Stock
               Exchange, the fees payable by the Owner to the New York Stock
               Exchange in connection with its listing, costs of preparing,
               printing and mailing the Owner's annual report to its
               shareholders and proxy materials with respect to any annual
               meeting of the shareholders of the Owner."

          4.  AMENDMENT TO SECTION 4.1.  Section 4.1 of the Original Advisory
Agreement is hereby amended by deleting subsections A and B thereof in their
entirety and substituting the following therefor:

              "A.  TERM.  From and after the date of the First Amendment to
          Advisory Agreement, dated as of May 21, 1997, between Owner and
          Manager, the term of this Agreement shall be for an initial term of
          three years expiring on May 20, 2000.  Thereafter, until this
          Agreement is terminated in accordance with its terms, this Agreement
          shall be deemed renewed automatically each year for an additional one
          year period unless the trustee (the "WAT Trustee") of the Westfield
          America Trust, an Australia publicly listed property trust, and 75% of
          the Independent Directors (as such term is defined in the Third
          Amended and Restated Articles of the Owner) of the Owner's Board of
          Directors agree that either (i) there has been unsatisfactory
          performance that is materially detrimental to the Owner or (ii) the
          fees payable to Advisor are not fair, PROVIDED that Owner shall not
          have the right to terminate this Agreement under clause (ii) above if
          Advisor agrees to continue to provide advisory services for the
          Property at a fee that the WAT Trustee and 75% of the independent
          members of the Board have determined to be fair and PROVIDED FURTHER
          that the WAT Trustee's agreement with respect to the matters set forth
          in clauses (i) or (ii) will only be required if the WAT Trustee is the
          owner of 10% or more of the outstanding capital stock of the Owner. 
          If Owner shall elect not to renew the term of this Agreement at the
          expiration of the initial term or any extended term as set forth
          above, Owner shall deliver to Advisor prior written notice of Owner's
          determination not to renew this Agreement based on the terms set forth
          in this subparagraph A not less than 30 days prior to the expiration
          of the then existing term.  If Owner elects not to renew this
          Agreement, Owner shall designate the date, not less than 60 nor more
          than 180 days from the date of the notice, on which Advisor shall
          cease to provide services hereunder and this Agreement shall terminate
          on such date.

               B.  NON-CURABLE TERMINATING EVENTS.  (i) The Owner may terminate
          this Advisory Agreement on not less than 30 days written notice to
          Advisor upon the occurrence of any of the following events:

                    (x) the Bankruptcy of Advisor; or 

                    (y) an act of fraud, embezzlement or theft constituting a
               felony against Owner or its Affiliates which causes it material
               injury is perpetrated by Advisor or by Developer or by Manager in
               its corporate capacity (as distinguished from the acts of any
               employees of such entities which are taken without the approval
               or complicity of the Board of Directors of such entities'
               managing general partner) under this Agreement, the Management
               Agreements, the Development Framework 


                                       3

               Agreements, any Development Agreement or any Leasing Agreement. 

               (ii) This Agreement shall terminate if Advisor shall notify Owner
          that advisory services shall cease to be one of the principal business
          undertakings of Westfield Holdings Limited in the United States,
          PROVIDED that this Advisory Agreement shall continue for a  period of
          180 days after delivery of such notice to Owner if Owner shall be
          reasonably satisfied with Advisor's ability to continue providing the
          services required hereunder during such period."

          5.  RATIFICATION.  Except as amended hereby, the Original Advisory
Agreement is hereby ratified and remains in full force and effect.

          6.  COUNTERPARTS.  This Amendment may be executed in any number of
counterparts, each of which shall be effective only upon delivery and thereafter
shall be deemed an original, and all of which shall be taken to be one and the
same instrument, with the same effect as if all parties hereto had all signed
the same signature page.  Any signature page of this Amendment may be detached
from any counterpart of this Agreement without impairing the legal effect of any
signatures thereon and may be attached to another counterpart of this Amendment 
identical in form hereto but having attached to it one more additional signature
pages.

          7.  EFFECTIVE DATE.  This Amendment shall be effective as of the
closing of the initial public offering of common stock of the Owner pursuant to
its Registration Statement on Form S-11 (No. 333-22731).
