                            IMPORTANT TAX INFORMATION

         In order to ensure compliance with federal income tax requirements,
each holder of shares of SDG Common Stock is requested to provide the Exchange
Agent with his or her correct TIN and to certify whether he or she is subject to
backup federal income tax withholding by completing and sign the Substitute Form
W-9 below.

         Federal income tax law requires that a holder whose tendered
Certificate(s) are accepted for exchange must provide the Exchange Agent (as
payor) with his or her correct taxpayer identification number ("TIN"), which, in
the case of a holder who is an individual, is his or her social security number.
If the Exchange Agent is not provided with the correct TIN, the holder may be
subject to a $50 penalty imposed by the Internal Revenue Service. In addition,
delivery to the holder of the Certificate(s) may be subject to back-up
withholding. (If withholding results in overpayment of taxes, a refund may be
obtained.) Exempt holders (including, among others, all corporations and certain
foreign individuals) are not subject to these back-up withholding and reporting
requirements.

         Under federal income tax laws, payments that may be made by SDG on
account of certificates of Simon Group Common Stock may be subject to back-up
withholding at a rate of 31%. In order to prevent back-up withholding, each
tendering holder must provide his or her correct TIN by completing the
"Substitute Form W-9" referred to above, certifying that the TIN provided is
correct (or that the holder is awaiting a TIN) and that: (i) the holder has not
been notified by the Internal Revenue Service that he or she is subject to
back-up withholding as a result of failure to report all interest or dividends;
or (ii) the Internal Revenue Service has notified the holder that he or she is
no longer subject to back-up withholding; or (iii) certify in accordance with
the Guidelines that such holder is exempt from back-up withholding. If the
Certificate(s) are in more than one name or are not in the name of the actual
owner, consult the enclosed Guidelines for information on which TIN to report.

NOTE: FAILURE TO COMPLETE AND RETURN THIS FORM MAY RESULT IN BACKUP WITHHOLDING
OF 31% OF ANY PAYMENTS MADE TO YOU PURSUANT TO THE OFFER. PLEASE REVIEW THE
ENCLOSED GUIDELINES FOR CERTIFICATION OF TAXPAYER IDENTIFICATION NUMBER ON
SUBSTITUTE FORM W-9 FOR ADDITIONAL DETAILS.

hereof must be properly filled in, dated and signed in BOX IV, and must be
delivered, together with all Certificate(s) for such shares of SDG Common Stock
held by such holder, duly endorsed in blank or otherwise in form acceptable for
transfer on the books of SDG.

         THE METHOD OF DELIVERY OF ALL DOCUMENTS IS AT THE OPTION AND RISK OF
THE HOLDERS, BUT IF SENT BY MAIL, REGISTERED MAIL, RETURN RECEIPT REQUESTED,
PROPERLY INSURED, IS SUGGESTED.

         2. INADEQUATE SPACE. If there is insufficient space on this Letter of
Transmittal to list all your Certificate(s), please attach a separate signed
schedule containing the information in BOX I.

         3. SIGNATURES ON THIS LETTER OF TRANSMITTAL; ASSIGNMENTS; GUARANTEE OF
SIGNATURES. The signature (or signatures, in the case of Certificate(s) owned by
two or more joint holders) on this Letter of Transmittal must correspond with
the name(s) as written on the face of the Certificate(s) for the Certificate(s)
submitted, without alteration, enlargement or any change whatsoever unless the
shares of SDG Common Stock described in this Letter of Transmittal have been
assigned by the registered holder(s), in which event this Letter of Transmittal
should be signed in exactly the same form as the name of the last transferee
indicated on the transfers attached to or endorsed on the Certificate(s).

         If this Letter of Transmittal is signed by a person or person other
than the registered owners of the Certificate(s) listed, the Certificate(s) must
be endorsed or accompanied by appropriate stock powers, in either case signed
exactly as the name(s) of the registered owner(s) appear on such Certificate(s).

         If this Letter of Transmittal or any Certificate(s) or stock power(s)
are signed by a trustee, executor administrator, guardian, officer of a
corporation, attorney-in-fact or any other person acting in a representative or
fiduciary capacity, the person signing must give such person's full title in
such capacity and appropriate evidence of authority to act in such capacity must
be forwarded with this Letter of Transmittal.

         4. MUTILATED, LOST, STOLEN OR DESTROYED CERTIFICATE(S). If your
Certificate(s) have been mutilated, lost, stolen or destroyed, please make note
of this fact on this Letter of Transmittal and the appropriate forms for
replacement will be sent to you. You will then be instructed as to the steps you
must take in order to receive a stock certificate representing a share of Simon
Group Common Stock.

         5. SPECIAL ISSUANCE AND DELIVERY INSTRUCTIONS. If the section entitled
"Special Payment Instructions" (BOX II) is completed, then signatures on this
Letter of Transmittal must be guaranteed by a firm that is a bank, broker,
dealer, credit union, savings association or other entity which is a member in
good standing of the Securities Transfer Agents' Medallion Program (each an
"Eligible Institution"). If the surrendered Certificate(s) are registered in the
name of a person other than the signer of this Letter of Transmittal, or if the
issuance is to be made to a person other than the registered owner(s), then the
surrendered Certificate(s) must be endorsed or accompanied by duly executed
stock power, in either case signed exactly as the name(s) of the registered
owner(s) appear on such Certificate(s) or stock power(s), with the signatures on
the Certificate(s) or stock power(s) guaranteed by an Eligible Institution as
provided herein.

         If the Certificate(s) are to be registered in the name of the
registered holder(s) of a share of SDG Common Stock, but are to be sent to
someone other than the registered holder(s) or to an address other than the
address of the registered holder, it will be necessary to indicate such person
or address in the section entitled "Special Delivery Instructions" (BOX III).

         6. SUBSTITUTE FORM W-9. Each surrendering stockholder is required to
provide the Exchanges Agent with such holder's correct TIN on the Substitute
Form W-9, which is a part of this Letter of Transmittal, and to certify whether
the stockholder is subject to backup withholding. Failure to provide such
information or an adequate basis for exemption on the form may subject the
surrendering stockholder to 31% Federal income tax withholding on payments made
to such surrendering stockholder with respect to the certificate(s). If such
holder is an individual, the TIN is his or her social security number. A holder
must check the box in Part 2 of Substitute Form W-9 if such holder is subject to
backup withholding. The box in Part 3 of the form should be checked if the
surrendering holder has not been issued a TIN and has applied for a TIM or
intends to apply for a TIN in the near future. If box 3 is checked, the
surrendering holder must also complete the Certificate of Awaiting Taxpayer
Identification Number in order to avoid backup withholding. Notwithstanding that
the box i Part 3 is checked and the Certificate of Awaiting Taxpayer
Identification Number is complete, the Exchange Agent will withhold 31% on all
payments made prior to the time a properly certified TIN is provided to the
Exchange Agent. However, such amount will be refunded to such surrendering
holder if a TIN is provided to the Exchange Agent within 60 days.

         7. TRANSFER TAXES. SDG will pay all transfer taxes, if any, applicable
to the transfer of Certificate(s) to it. If, however, Certificate(s) not
exchanged are to be delivered to, or are to be issued in the name of, any person
other than the record holder, or if tendered certificates are recorded in the
