This Amendment No. 28 to the Schedule TO is being filed on behalf of the Purchaser, SPG Inc. and Westfield America, Inc. ("WEA"). Capitalized terms used and not defined herein shall have the meanings assigned to such terms in the Offer to Purchase, the Supplement and the Schedule TO, as applicable. The item numbers and responses thereto below are in accordance with the requirements of Schedule TO. Item 7. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION. Item 7 of the Schedule TO is hereby amended and supplemented by deleting the penultimate paragraph under Section 8, "Source and Amount of Funds," in the Supplement to the Offer to Purchase and inserting in its place the following paragraphs: Westfield America Limited Partnership ("WALP") has obtained from UBS Warburg Real Estate Investments Inc. and Lehman Brothers Bank FSB (or an affiliate thereof), a commitment letter, dated April 8, 2003 providing for a credit facility (the "WALP Credit Facility") in an aggregate amount of up to $750 million for a 36 month term. The WALP Credit Facility will provide sufficient funds for WEA or its designated assignee to acquire 50% of the Purchaser (or its designee) upon completion of the Offer. WEA will unconditionally guarantee all obligations under the WALP Credit Facility. The commitment letter dated January 15, 2003 from Deutsche Bank AG, Cayman Islands Branch, and UBS AG, Stamford Branch to WEA which provided for a credit facility in an aggregate amount of up to $550 million expired undrawn on May 14, 2003. The WALP Credit Facility will consist of two tranches: Tranche A in an amount up to $450 million ("Tranche A") and Tranche B in an amount up to $300 million ("Tranche B"). Amounts drawn and outstanding under Tranche A will bear interest at WALP's option at a rate equal to (i) the greater of (A) 30-day LIBOR and (B) 1.20% per annum plus, in each case, a margin of 1.15% (the "Tranche A Margin") or (ii) the "Adjusted Base Rate" for such day plus the Tranche A Margin, where the "Adjusted Base Rate" is equal to the higher of (A) the Prime Rate for such day and (B) 0.50% plus the Federal Funds Rate. Tranche A will be secured by a first mortgage lien on certain real estate properties of WALP or one or more of its subsidiaries. Amounts drawn and outstanding under Tranche B will bear interest at WALP's option at a rate equal to (i) the greater of (A) 30-day LIBOR and (B) 1.20% per annum plus, in each case, a margin of 2.50% (the "Tranche B Margin") or (ii) the "Adjusted Base Rate" for such day plus the Tranche B Margin. Tranche B will be secured by, if not restricted by the terms of certain existing agreements or the terms of certain existing indebtedness, a pledge of WALP's equity interest in any U.S. subsidiary that owns, directly or indirectly, real estate assets, which equity interests must have an aggregate value of the lesser of (i) 200% of the then outstanding principal balance of the Tranche B facility and (ii) $500,000. The WALP Credit Facility will contain customary representations and warranties, covenants, voluntary and mandatory repayment provisions and events of default. WALP expects to repay the borrowings under the WALP Credit Facility out of cash from operations, the proceeds from other short- and long-term debt financings, joint venture equity, asset sales and/or issuances of securities. WEA currently does not have alternative financing arrangements in the event that it does not obtain financing under its primary financing plans. A copy of the commitment letter for the WALP Credit Facility, dated April 8, 2003, is filed herewith as Exhibit (a)(5)(zz). Item 11. ADDITIONAL INFORMATION.
