  (the &#147;Company&#148;), in its capacity as the sole general partner of Simon Property
  Group, L.P. (the &#147;Operating Partnership&#148;), after having received the required
  approval of the partners, executed the Eighth Amended and Restated Agreement of
  Limited Partnership of the Operating Partnership (the &#147;Restated Partnership
  Agreement&#148;).&#160; The Restated Partnership
  Agreement reflects a number of structural changes, including acquisitions and
  internal reorganizations, that the Operating Partnership has experienced since
  1999.&#160; In addition, the Restated
  Partnership Agreement changes provisions relating to the allocation of profits
  to preferred units and adds new provisions authorizing the general partner to
  issue long-term incentive plan interests in the Operating Partnership (the &#147;LTIP
  units&#148;).&#160; LTIP units represent &#147;profits
  interest&#148; in the Operating Partnership that are subject to forfeiture if
  specified performance measures are not achieved during the performance period
  expected to be longer than one year.&#160; The
  holders of LTIP units will have no capital account at the time of issuance and,
  until the performance period expires, will be entitled to receive distributions
  equal to one-tenth the rate paid on the partnership units.&#160; The number of LTIP units that the general
  partner can issue at any time cannot exceed the number of shares of the Company&#146;s
  common stock that have been reserved and are available for issuance under
  stockholder approved equity-based incentive plans.</font></p>

  ITEM 1.01
  ENTRY INTO A MATERIAL DEFINITIVE
  AGREEMENT
  Amendment and Restatement of Agreement of Limited Partnership
  On May 8, 2008, Simon Property Group, Inc.
  (the "Company"), in its capacity as the sole general partner of Simon Property
  Group, L.P. (the "Operating Partnership"), after having received the required
  approval of the partners, executed the Eighth Amended and Restated Agreement of
  Limited Partnership of the Operating Partnership (the "Restated Partnership
  Agreement").  The Restated Partnership
  Agreement reflects a number of structural changes, including acquisitions and
  internal reorganizations, that the Operating Partnership has experienced since
  1999.  In addition, the Restated
  Partnership Agreement changes provisions relating to the allocation of profits
  to preferred units and adds new provisions authorizing the general partner to
  issue long-term incentive plan interests in the Operating Partnership (the "LTIP
  units").  LTIP units represent "profits
  interest" in the Operating Partnership that are subject to forfeiture if
  specified performance measures are not achieved during the performance period
  expected to be longer than one year.  The
  holders of LTIP units will have no capital account at the time of issuance and,
  until the performance period expires, will be entitled to receive distributions
  equal to one-tenth the rate paid on the partnership units.  The number of LTIP units that the general
  partner can issue at any time cannot exceed the number of shares of the Company's
  common stock that have been reserved and are available for issuance under
  stockholder approved equity-based incentive plans.
  The foregoing summary of the Restated Partnership
  Agreement is qualified in its entirety by reference to the copy of the Restated
  Partnership Agreement which is attached hereto as
  Exhibit 10.1
  to
  this Current Report on Form 8-K and incorporated herein by reference.
  Amendment of 1998 Stock Incentive
  Plan
  On May 8, 2008, the stockholders of the Company
  approved amendments to the Simon Property Group, L.P. 1998 Stock Incentive Plan
  (the "1998 Plan").  The amendments extend
  the term of the 1998 Plan to December 31, 2013, change the definition of
  fair market value, delete provisions authorizing reload options, revise the
  definition of performance units to include awards of equity interests in the
  Operating Partnership that would be exchangeable for the Company's common stock
  and extend the prohibition on repricing of stock options to stock appreciation
  rights.
  The foregoing summary is qualified in its entirety
  by reference to the Simon Property Group, L.P. 1998 Stock Incentive Plan (as
  amended May 8, 2008) attached as
  Exhibit 10.2
  to this Current
  Report on Form 8-K and incorporated herein by reference.
