The Order stayed the Court's Amended Opinion and Order issued on May 8, 2003 which preliminarily enjoined the voting of all of the shares held or controlled by the Taubman family and its associates (together purportedly comprising approximately 33.6% of the Company's voting power) until voting rights are conferred on such shares through a disinterested shareholder vote in compliance with the Michigan Control Share Act, pending appeal of the Amended Opinion and Order to the United States Court of Appeals for the Sixth Circuit (the "Appeal"). The Court also ruled in the Order that, pending the Appeal, the Company is restricted from engaging in any activity to impede the Offer, including, but not limited to, repurchasing shares, adopting a shareholders' rights plan such as a poison pill, amending the By-Laws, calling a meeting of the Company's shareholders, and asking for consents and/or designations of the Company's shareholders.

                           OF PRELIMINARY INJUNCTION

      This matter is before the Court on Defendants' Motion to Suspend
Injunction Pending Appeal [DOC # 90]. For the reasons stated below, the Court
GRANTS Defendants' motion.

I.    ARGUMENTS

      On May 8, 2003, the Court entered an Order Granting Plantiffs' Motion for
Preliminary Injunction. The Order enjoined Defendants from enforcing the Meeting
Delay Amendment to the bylaws of Taubman Centers, Inc. (TCI) and enjoined the
Taubman family and signatories of certain voting agreements from voting shares
of TCI totaling 33.6%. As a result of this Court's preliminary ruling,
Plaintiffs Simon Property Group, Inc. and Simon Property Acquisitions, Inc.
(collectively referred to as "Simon") seek to move forward on their bid to
acquire all of the outstanding shares of TCI.



      Defendants filed a Notice of Appeal of the May 8th Order to the Sixth
Circuit Court of Appeals. They request that this Court stay its injunction
pending appellate review.

      The Taubman family has been vocal in its opposition to Simon's takeover
bid and, if allowed to vote their shares, would likely be able to defeat
Simon's efforts. Consequently, Defendants assert that if the stay is denied,
Defendants could be denied meaningful appellate review: Simon could complete
all of the necessary steps to finalize its takeover before the Sixth Circuit
reviews Defendants' appeal.

      Both Plaintiffs and Defendants have stated their interest in an expedited
review of the appeal. Defendants will make a formal request for such a review.
Simon asserts that it is unlikely that it could complete a takeover before the
Sixth Circuit rules. Moreover, Simon has offered to refrain from taking any
"irreversible" steps toward a merger pending appellate review. However, Simon
asserts that it should be allowed to: 1) solicit the votes required to call a
special meeting; and, 2) call such a meeting if it is successful in its
solicitation. The purpose of the meeting would be to request that shareholders
vote in favor of an amendment to the TCI Articles of Incorporation, which would
eliminate the Excess Share Provision as to Simon and permit it to purchase the
shares necessary for it to succeed in its takeover bid. If two-thirds of the
shareholders vote in favor of the amendment, Simon could immediately begin
purchasing tendered shares.

      Once the requisite number of shares is acquired, Simon could then
proceed

                                       2


to the final steps necessary to effectuate a merger. Simon regards only these
final steps as irreversible, and will agree not to take them until the Sixth
Circuit has ruled.(1) Simon further stated a willingness to: 1) extend the
tender offer date(2); 2) not take any action to formally implement the bylaw
amendment if shareholders approve it; and, 3) assuming that it is successful,
not remove directors or exercise any management control in TCI.

      Defendants oppose the partial stay that Simon proposes. They contend that
only a stay of the injunction in its entirety will maintain the status quo as to
both parties. If the Court is affirmed by the Sixth Circuit, Simon's proposal,
says Defendants, would poise Simon to complete a takeover shortly after the
ruling. Thus, even before a ruling, Defendants say they would be forced to take
measures to ensure that shareholders receive the maximum value. Specifically,
Defendants contend they may be forced to solicit competitive bids and/or place
TCI up for auction, so that shareholders have the benefit of other options if
Simon calls a special meeting.

      If the Court grants the stay in its entirety, Defendants have offered to
refrain

- ----------
      1 During a conference call with counsel and the Court, Simon's counsel
suggested that an appellate ruling could reverse Simon's purchase of tendered
shares. However, counsel did not direct the Court to any authority for this
proposition and it is not clear how an appellate ruling could effectively undue
a sale of shares to Simon by numerous shareholders, when those shareholders are
not parties to this litigation and the value of the shares is subject to market
forces.

      2 Per Simon's counsel, the current expiration date is May 30, 2003.


                                       3


from taking any steps to impede Simon's tender offer pending the Sixth Circuit
ruling. Defendants indicate that they would specifically refrain from: 1)
repurchasing shares; 2) adopting a shareholders' rights plan, i.e. "poison
pill"; 3) amending the bylaws; 4) calling a shareholder's meeting; and 5)
asking for consents and/or designations by shareholders.

      Defendants assert several reasons why they disagree with this Court's
Order Granting Plaintiff's Motion for Preliminary Injunction. They argue that
there are serious questions going to the merits of the injunction. Defendants
further assert that they will be irreparably harmed if a stay is denied because
they may suffer: 1) a sale or acquisition of TCI for an inadequate price; 2)
loss of the opportunity to vote on the future of TCI by its largest shareholder;
and, 3) actual and consequential monetary damages in the multimillions.

      Simon disputes these challenges. It also contends that Defendants'
claimed monetary damages are speculative. Simon further argues that
Defendants will not be irreparably harmed if Simon is allowed to take all
steps short of completing a merger, because Defendants are at liberty to take
any steps that they deem necessary to solicit other bids. If Defendants
prevail, says Simon, the Sixth Circuit can simply nullify actions taken by
Simon to effect the merger. Conversely, Simon argues that, if the stay is
granted, it will be irreparably harm because it will "lose the benefit of its
victory" and shareholders will be deprived of their right to decide whether
to accept Simon's takeover bid for several more months.

II.    STANDARD OF REVIEW

      A motion to stay an injunction pending appeal is governed by FRCP 62(c)
which states in relevant part:

            When an appeal is taken from an interlocutory or
            final judgment granting, dissolving, or denying
            an injunction, the court in its discretion may
            suspend, modify, restore, or grant an injunction
            during the pendency of the appeal upon such
            terms as to bond or otherwise as it considers
            proper for the security of the rights of the
            adverse party.

      A court must consider the following factors when deciding whether to issue
a stay:

            (1)   whether the stay applicant has made a strong showing that he
                  is likely to succeed on the merits;
            (2)   whether the applicant will be irreparably injured absent a
                  stay;
            (3)   whether issuance of the stay will substantially injure the
                  other parties interested in the proceeding; and
            (4)   where the public interest lies.

HILTON v BRAUNSKILL, 481 U.S. 770, 776 (1987); MICHIGAN COALITION OF RADIOACTIVE
MATERIAL USERS, INC. v GRIEPENTROG, 945 F.2d 150, 153 (6th Cir. 1991). "These
factors are not prerequisites that must be met, but are interrelated
considerations that must be balanced together." MICHIGAN COALITION, 945 F.2d at
153.

      Although the movant is required to establish the same factors that are
required for a grant of a preliminary injunction, "a movant need not always
establish a high probability of success on the merits." ID. Rather, "[t]he
probability of success that must be demonstrated is inversely proportional to
the amount of irreparable injury plaintiffs will suffer absent the stay." ID. In
other words, a greater showing on some elements allows for less of a showing
on others. Nevertheless, at



                                       5



a minimum, to satisfy the first element, a movant must at least show "serious
questions going to the merits." ID at 154 (quoting IN RE DELOREAN MOTOR CO.,
755 F.2d 1223, 1229 (6th Cir. 1985)).

      When evaluating the harm that may be suffered by either party, a court
must consider: (1) the substantiality of the injury alleged; (2) the likelihood
of its occurrence; and, (3) the adequacy of the proof provided. ID. Potential
harm that is compensable or otherwise may be corrected by later rulings of the
court are not irreparable:

      In evaluating the degree of injury, it is important to remember that [t]he
      key word in this consideration is irreparable. Mere injuries, however
      substantial, in terms of money, time and energy necessarily expended in
      the absence of a stay, are not enough. The possibility that adequate
      compensatory or other corrective relief will be available at a later date,
      in the ordinary course of litigation, weighs heavily against a claim of
      irreparable harm.

ID (citations omitted). Furthermore, "the harm alleged must be both certain and
immediate, rather than speculative or theoretical." ID.


III.    ANALYSIS

      A. LIKELIHOOD OF SUCCESS ON THE MERITS

      The Court is not persuaded by Defendants' substantive claims of error in
the Court's issuance of a preliminary injunction. However, when considering this
factor in the context of a request for a stay, a court is not required to find a
substantial likelihood that the movant will be successful on appeal. Rather, a
movant can satisfy this element where substantial legal questions or matters of
first impression


                                       6



are at issue and the equities favor maintaining the status quo. See MICHIGAN
COALITION, 945 F.2d at 154; SWEENEY v BOND, 519 F.Supp. 124, 132 (E.D. Mo.
1981); ROBINSON RUBBER PRODUCTS CO., INC. v HENNEPIN COUNTY, 927 F.Supp. 343,
346 (D.Minn. 1996). The Court finds that the Defendants have raised serious
legal questions regarding interpretation of the Michigan Control Share
Acquisitions Act, MCL 450.1790, ET SEQ, which have yet to be clearly
addressed in this Circuit. Therefore, the Court finds that this element
weighs in favor of granting a stay.

      B. BALANCE OF HARMS

      The Sixth Circuit's resolution of the legal issues raised by Defendants
will significantly impact the future course of Simon's takeover bid. Defendants
have adequately demonstrated that they will suffer irreparable harm which
outweighs any potential harm to Simon if a stay is not granted.

      A stay prohibiting Simon from proceeding and Defendants from impeding
the takeover bid appears to be the best means to preserve all rights pending
appellate review. Without a stay and presuming that Simon is successful in
calling and in the outcome of a special meeting to amend the TCI Articles of
Incorporation, the parties agree that Simon would be free to move forward
with its takeover bid. It could then effectuate a merger within a short
period of time after the Articles are amended in its favor. This would result
in a change of ownership through the purchase of shares from numerous
shareholders who are not parties to this action. While certain of the steps
along the way, such as the vote to amend the Articles,

                                       7


could be nullified by the Sixth Circuit, it is not clear that certain other
steps would be reversible or compensable if Defendants prevail on appeal.
Specifically, it is not clear that the Sixth Circuit could require tendering
shareholders to buy back tendered shares. Certainly the status quo would be
irreversibly altered if the tender could not be undone.

      Defendants do not wish to sell TCI. However, to avoid an uncontested
takeover by Simon, they say they would be forced to engage in allowable tactics
to counter Simon's bid while their appeal is pending. Most obviously, Defendants
could be forced to put TCI up for sale by soliciting other bidders or holding
an auction. Simon says that it is entitled to force Defendants' hand at this
time and in this manner; otherwise, it will lose the benefit of its victory.

      Simon's argument ignores the fact that the Court's ruling is
preliminary, not final, and is intended only to preserve Simon's rights until
a final decision on the merits. A complete stay would do just that; it would
preserve Simon's right to have its tender offer considered by shareholders.
Then, if Simon prevails on appeal, it will have the same right to call a
meeting and purchase shares that it currently has and Defendants will have
the same opportunity that it currently has to engage in counter measures. On
the other hand, if Defendants prevail on their appeal, the Taubman family
would be allowed to vote on the future of TCI. For these reasons, the Court
finds that the balance of harms weighs in favor of Defendants.

      C. PUBLIC INTEREST

      The Court finds that it is in the public interest to preclude efforts to
either advance or impede Simon's takeover bid until legal issues that impact
upon the manner in which the bid can proceed, and whether the Taubman family
will be allowed to vote all or any portion of their shares, are resolved by the
Sixth Circuit.

IV.    SECURITY BOND

      Under the express language of FRCP 62(c), the Court may set bond in any
amount it deems appropriate "for the security of the rights of the adverse
party." Simon has not presented any evidence of or otherwise identified specific
monetary damages that it may suffer as a result of the stay. Rather, it only
suggests in a footnote that the Court impose a bond of $325 million, which
purportedly represents the difference between the Simon/Westfield tender offer
price for TCI's outstanding shares and the market price of those share prior to
the tender offer. Simon, however, does not cite any authority that demonstrates
that it would be entitled to this measure of damages. Simon's assertion that it
may incur damages in the proposed bond amount is, therefore, purely speculative.
As such, security is not necessary to protect Simon's interests. Defendants are
not required to post a bond pending appeal.

V.    CONCLUSION

      After balancing the factors to be considered under FRCP 62(c), the Court
is persuaded that a stay of its injunction, in its entirety, is warranted.
Defandants'


                                       9


Motion to Suspend Injunction Pending Appeal is GRANTED.

      The Court further Orders that:

      A.    Defendants shall move for expedited review of its appeal in the
            Sixth Circuit;

      B.    While Defendants' appeal is pending, they shall refrain from
            engaging in any activity to impede Simon's tender offer, including,
            but not limited to:

              i.      repurchasing shares;
              ii.     adopting a shareholders' rights plan, i.e. "poison pill";
              iii.    amending the bylaws;
              iv.     calling a shareholder's meeting; and
              v.      asking for consents and/or designations by shareholders.

      C.    Nothing in this Order prohibits Simon from extending its tender
            offer beyond May 30, 2003.


IT IS SO ORDERED.
