     Operating History; Future Prospects. With respect to the derivative lawsuit
filed  against the prior  officers  and  directors of the Dunes,  the  following
persons are named as  defendants  in the lawsuit:  John B.  Anderson,  Andrew J.
Marincovich,  Erik J.  Tallstrom,  Brent L.  Bowen,  Edward  Pasquale,  Wayne O.
Pearson, M. Arthur Shenker, Jr., Anthony Smernes, Jr., Donald J. O'leary, Burton
M. Cohen,  Anthony A. Zmalia, Kent N. Calfee,  Estate of James Dale, Greg Schmid
and Dunes Hotels and Casinos, Inc.  Additionally,  any other unknown individuals
that were  involved  in the real estate  transactions  that are the basis of the
alleged  wrong-doing  were  included as  defendants  "Does 1 through  100".  The
Plaintiffs allege total potential damages of approximately $15 million. However,
as of  October  25,  2001,  the  Plaintiffs  had not done any due  diligence  to
determine whether any significant assets other than the $3,000,000 directors and
officers liability  insurance policy would be available to satisfy any judgment.
Any  expenses of the  plaintiffs  in pursuing  the  litigation  and any costs of
defense of former officers and directors  covered by the insurance  policy would
be deducted from any insurance proceeds payable to the Dunes.

     Fairness of the Offer.  The  discussion  as to the fairness of the Offer in
the Offer to  Purchase  is hereby  supplemented  with the  following  additional
information.

     The Offer was not structured using certain  mechanisms that are designed to
make the Offer procedurally fair to the unaffiliated shareholders.  For example,
the  Board of  Directors  and the GFS  Group  did not (1)  hire an  unaffiliated
representative  to act  solely on behalf of the  unaffiliated  shareholders  for
purposes of negotiating the terms of the Offer, (2) receive any report,  opinion
or appraisal from an outside party with respect to the value of the






Dunes or the value of the  Shares,  or (3) seek to have the Offer  approved by a
majority of the  unaffiliated  shareholders of the Dunes. The Board of Directors
and the GFS Group determined that the Offer was procedurally  fair,  because (1)
each  shareholder  will have the  ability to  determine  for  itself  whether to
receive the offered  consideration or remain a shareholder of the Dunes, (2) the
Offer was approved by all of the independent  directors of the Dunes and (3) the
Board of Directors  (including  all of the  independent  directors)  and the GFS
Group  determined that due to the nature and limited number of the Dunes' assets
and  the  business  experience  of the  independent  directors  that  the use of
unaffiliated  representatives  and/or  obtaining a report,  opinion or appraisal
were not required in order to fairly evaluate or structure the Offer.

     Although  the  Board of  Directors  believes  that the Offer is fair to the
unaffiliated  shareholders of the Dunes, it is not making a recommendation  with
respect  to the  Offer,  because  the  Board of  Directors  believes  that  each
shareholder  is in the best position to decide,  based upon their own assessment
of current  market  value of the  Shares and  individual  liquidity  needs,  tax
considerations and investment objectives,  whether tendering their Shares in the
Offer or remaining a shareholder of the Dunes is in their best interest.

     Conclusion Regarding Tax Treatment of the Dunes and Shareholders. We hereby
by delete the first  sentence  of the last  paragraph  of  "Special  Factors--4.
Material Federal Income Tax Consequences--Conclusion  Regarding Tax Treatment of
the Dunes and Shareholders."

     Transactions and  Arrangements  Concerning  Shares.  The information in the
Offer to  Purchase  under the  caption  "Special  Factors--7.  Transactions  and
Arrangements  Concerning  Shares" is  supplemented  by the following  additional
information:

     As described in the Offer to Purchase  under "Special  Factors--2.  Purpose
     and Fairness of the Offer", the Dunes,  Steve K. Miller,  General Financial
     Services,  Inc. and GFS Acquisition  Company,  Inc. previously  conducted a
     tender  offer for all of the Dunes'  Common  Stock and  Series B  Preferred
     Stock. On October 31, 2000, the Dunes commenced the prior tender offer. The
     tender  offer for the Common  Stock  expired on  February  15, 2001 and the
     tender offer for the Series B Preferred Stock expired on March 16, 2001. As
     a result of the prior tender offer,  the Dunes  acquired  445,097 shares of
     Common  Stock  (representing  approximately  8.7% of the  then  outstanding
     Common  Stock) and 1,291 shares of Series B Preferred  Stock  (representing
     approximately  13.4% of the then outstanding Series B Preferred Stock). The
     acquired shares are currently being held as treasury stock.

     Conditions  to the  Offer to  Purchase.  The  information  in the  Offer to
Purchase under the caption "The  Offer--8.  Conditions to the Offer" is replaced
with the following:

          acquisition of any Shares  pursuant to the Offer,  seeking to restrain
          or prohibit the making or  consummation of the Offer, or alleging that
          any such  acquisition  or other  transaction  relates to,  involves or
          constitutes  a breach of fiduciary  duty by the Dunes'  directors or a
          violation of federal securities law or applicable corporate law or (B)
          seeking to impose a material  condition  to the Offer  which  would be
          adverse to the Dunes' shareholders;

     (2)  there  will  be  any  statute,  rule,  regulation,  judgment, order or
          injunction   enacted,   entered,   enforced,   promulgated  or  deemed

          governmental  entity or court, that is reasonably likely to result, in
          any  of  the  consequences  referred  to in  clauses  (A)  and  (B) of
          paragraph (1) above;


                                       2



     (3)  there  will have occurred (A) any general suspension of, shortening of
          hours for or  limitation  on prices for trading in  securities  in the
          over-the-counter   market   (whether  or  not   mandatory),   (B)  any
          significant adverse change in the price of the Shares or in the United
          States' securities or financial markets, (C) a significant  impairment
          in the trading market for equity securities,  (D) the declaration of a
          banking  moratorium or any  suspension of payments in respect of banks
          in the United States (whether or not mandatory),  (E) the commencement
          of a  war,  armed  hostilities  or  other  international  or  national

          a  material  adverse  effect  on the  Dunes  or  materially  adversely
          affecting (or materially  delaying) the consummation of the Offer, (F)
          any  limitation or proposed  limitation  (whether or not mandatory) by
          any U.S.  governmental  authority or agency,  or any other event, that
          materially  adversely  affects  generally  the  extension of credit by
          banks or other  financial  institutions,  or (G) in the case of any of
          the situations described in clauses (A) through (F) inclusive existing
          at the date of  commencement  of the Offer,  a material  escalation or
          worsening thereof; or

     (4)  there  will have occurred or be likely to occur any event or series of
          events that, in the reasonable  judgment of the Dunes,  would or might
          prohibit, prevent, restrict or delay consummation of the Offer or that
          will, or is reasonably likely to, otherwise result in the consummation
          of the Offer not  being or not  being  reasonably  likely to be in the
          best interest of the Dunes;

which, in the reasonable  judgment of the Dunes, in the case of (1), (2), (3) or
(4), and  regardless  of the  circumstances  giving rise to any such  condition,
makes it  inadvisable  to  proceed  with the Offer or with such  acceptance  for
payment or payment for Shares.

     The  foregoing  conditions  are for the sole  benefit  of the Dunes and its
affiliates  and may be asserted  by the Dunes  regardless  of the  circumstances
giving  rise to such  condition  or may be  waived  by the  Dunes  prior  to the
Expiration  Date in whole  or in part at any  time and from  time to time in its
reasonable judgment. If any condition to the Offer is not satisfied or waived by
the Dunes prior to the Expiration  Date, the Dunes reserves the right (but shall
not be  obligated),  subject to  applicable  law, (i) to terminate the Offer and
return the tendered Shares to the tendering shareholders; (ii) to waive prior to
the  Expiration  Date all  unsatisfied  conditions  and accept for  payment  and
purchase all Shares that are validly  tendered (and not withdrawn)  prior to the
Expiration  Date; (iii) to extend the Offer and retain the Shares that have been
tendered during the period for which the Offer is extended; or (iv) to amend the
Offer.  You will  continue  to have  withdrawal  rights for the  duration of any
extension of the offer,  including  any  extension  that results from a material
amendment of the Offer.  The failure by the Dunes at any time to exercise any of
the  foregoing  rights  will not be deemed a waiver of or  otherwise  affect any
other  rights and each such right will be deemed an ongoing  right  which may be
asserted  at any time and from time to time prior to the  Expiration  Date.  Any
determination  by the Dunes  concerning the events described above will be final
and binding upon all parties.

     There is no minimum number of Shares that must be tendered in the Offer.
