  ITEM
  1.01  Entry into a Material Definitive
  Agreement.
  On May 12,
  2008, Simon Property Group, L.P. ("Operating Partnership") entered into an
  underwriting agreement (the "Underwriting Agreement") with Banc of America Securities
  LLC, Citigroup Global Markets Inc., Deutsche Bank Securities Inc. and Goldman,
  Sachs & Co. as representatives of the underwriters named therein
  (collectively, the "Underwriters"), in connection with the Operating
  Partnership's offering of $700 million aggregate principal amount of 5.300%
  notes due 2013 (the "2013 Notes") and $800 million aggregate principal amount
  of 6.125% notes due 2018 (the "2018 Notes" and, together with the 2013 Notes,
  the "Notes").  The offering of the Notes
  is expected to close on May 19, 2008.
  The Notes will
  be issued pursuant to the twentieth supplemental indenture (the "Supplemental
  Indenture") to the Indenture (the "Indenture") dated as of November 26,
  1996, between the Operating Partnership and The Bank of New York Trust Company,
  N.A. (as successor to The Chase Manhattan Bank), as trustee.  For a description of the material terms of
  the Supplemental Indenture and the Notes, see the information set forth below
  under Item 2.03, which is incorporated into this Item 1.01.
  The Notes are
  subject to the Registration Statement on Form S-3 (Registration No. 333-132513-01),
  the prospectus dated March 17, 2006, and the related prospectus supplement
  dated May 12, 2008, relating to the public offering of the Notes.
  A copy of the
  Underwriting Agreement and the form of Supplemental Indenture are attached
  hereto as Exhibits 1.1 and 4.1, respectively, and are incorporated herein by
  reference.  The Indenture was
  incorporated by reference into the Registration Statement.
  ITEM
  2.03  Creation of a Direct Financial
  Obligation or an Obligation under an Off Balance Sheet Arrangement of a
  Registrant.
  The 2013 Notes
  bear interest at a rate of 5.300% per annum and mature on May 30, 2013.  The 2016 Notes bear interest at a rate of
  6.125% per annum and mature on May 30, 2018.  Interest on both series of Notes is payable
  semi-annually in arrears on May 30 and November 30 each year,
  beginning on November 30, 2008 (each, an "Interest Payment Date").  Interest will be paid to holders of record of
  such Notes registered at the close of business the fifteenth calendar day
  preceding the related Interest Payment Date.
  The
  Supplemental Indenture contains certain financial covenants that, among other
  things, (i) limit the amount of debt and secured debt that the Operating
  Partnership may have outstanding as of certain dates, and (ii) requires
  the Operating Partnership to maintain certain fixed charge coverage ratios and
  unencumbered assets.  However, these
  covenants will not apply to the Notes for so long as any securities issued
  under prior supplemental indentures remain outstanding or until the covenants
  in the prior supplemental indentures have been amended.  Until such time, the covenants applicable to
  all currently outstanding securities issued under prior supplemental indentures
  will apply to the Notes.
  The Operating
  Partnership may, at its option, redeem either series of Notes in whole at any
  time or in part from time to time on not less than 30 and not more than 60 days'
  prior written notice mailed to the holders of such series of Notes to be
  redeemed.  The Notes will be redeemable
  at a price equal to the principal amount of such series of Notes being
  redeemed, plus
  2
  accrued
  and unpaid interest to the date of redemption and a "make-whole" premium
  calculated under the Supplemental Indenture (unless such series of Notes is
  redeemed within 90 days prior to the applicable maturity date, in which case no
  "make-whole" will be payable).
  The
  Supplemental Indenture provides for customary events of default, including,
  among other things, nonpayment, failure to comply with the other agreements in
  the Supplemental Indenture for a period of 90 days, and certain events of
  bankruptcy, insolvency and reorganization.
  The description
  set forth above is qualified in its entirety by the form of Supplemental
  Indenture (including the form of notes attached thereto).

  2008, Simon Property Group, Inc., the general partner of the Operating
  Partnership, issued a press release announcing the offering of the Notes.  A copy of the press release is attached
