     (a) To advise the  Initial  Purchaser  promptly  and, if  requested  by the
Initial  Purchaser,  confirm such advice in writing,  (i) of the issuance by any
state securities  commission of any stop order  suspending the  qualification or
exemption from  qualification  of any Series A Notes for


                                       4



offering  or  sale  in any  jurisdiction  designated  by the  Initial  Purchaser
pursuant to Section 5(e) hereof,  or the  initiation  of any  proceeding  by any
state securities  commission or other federal or state regulatory  authority for
such purpose and (ii) of the  happening of any event during the period  referred
to in Section 5(c) hereof that makes any  statement  of a material  fact made in
the Preliminary  Offering Circular or the Final Offering Circular untrue or that
requires the making of any additions to or changes in the  Preliminary  Offering
Circular or the Final Offering Circular in order to make the statements  therein
not  misleading.  The Company shall use its best efforts to prevent the issuance
of any stop order or order  suspending the  qualification or exemption of any of
Series A Notes under any state  securities or Blue Sky laws,  and if at any time
any state securities  commission or other federal or state regulatory  authority
shall issue an order  suspending the  qualification or exemption of any Series A
Notes under any state  securities  or Blue Sky laws,  the Company  shall use its
best efforts to obtain the  withdrawal  or lifting of such order at the earliest
possible time.

     (b) To furnish the Initial  Purchaser and those  persons  identified by the
Initial  Purchaser  to the  Company as many copies of the  Preliminary  Offering
Circular and the Final  Offering  Circular,  and any  amendments or  supplements

Purchaser's  compliance with its  representations  and warranties and agreements
set  forth  in  Section  8  hereof,  the  Company  consents  to  the  use of the
Preliminary  Offering  Circular  and  the  Final  Offering  Circular,   and  any
amendments and supplements  thereto  required  pursuant  hereto,  by the Initial
Purchaser in connection with Exempt Resales.

     (c)  During  such  period as in the  opinion  of  counsel  for the  Initial
Purchaser an Offering  Circular is required by law to be delivered in connection
with  Exempt   Resales  by  the  Initial   Purchaser  and  in  connection   with
market-making  activities  of the Initial  Purchaser for so long as any Series A
Notes  are  outstanding,  (i) not to make any  amendment  or  supplement  to the
Offering  Circular of which the Initial Purchaser shall not previously have been
advised or to which the Initial Purchaser shall reasonably object after being so
advised and (ii) to prepare  promptly  upon the Initial  Purchaser's  reasonable
request,  any  amendment or  supplement  to the Offering  Circular  which may be
necessary  or  advisable  in  connection   with  such  Exempt  Resales  or  such
market-making activities.

     (d) If,  during the period  referred to in Section  5(c)  above,  any event
shall occur or  condition  shall exist as a result of which,  in the judgment of
the Company or in the reasonable  judgment of counsel to the Initial  Purchaser,
it becomes  necessary to amend or supplement  the Offering  Circular in order to
make the  statements  therein,  in the  light  of the  circumstances  when  such
Offering Circular is delivered to an Eligible Purchaser, not misleading,  or if,
in the reasonable judgment of counsel to the Initial Purchaser,  it is necessary
to amend or supplement the Offering  Circular to comply with any applicable law,
forthwith  to  notify  the  Initial  Purchaser  and to  prepare  an  appropriate
amendment  or  supplement  to such  Offering  Circular  so that  the  statements
therein,  as so  amended  or  supplemented,  will  not,  in  the  light  of  the
circumstances when it is so delivered,  be misleading,  or so that such Offering
Circular  will  comply  with  applicable  law,  and to  furnish  to the  Initial
Purchaser  and such other persons as the Initial  Purchaser  may designate  such
number of copies thereof as the Initial  Purchaser may reasonably  request.

"Material Adverse Effect").

aggregate, would not have a Material Adverse Effect.

     (o) Other than as disclosed in the Offering Circular, there exists no fact,
and no event  has  occurred,  which  has or is  reasonably  likely  to result in

liability for investigatory costs, cleanup costs,  governmental  response costs,
natural resource damages,  property damages,  personal injuries or penalties) of
the Company  arising out of, based on or resulting  from the presence or release
into the environment of any hazardous material (including without limitation any
pollutant or contaminant or hazardous,  dangerous or toxic  chemical,  material,
waste or substance  regulated  under or within the meaning of any  Environmental
Law) or any  violation  of any  Environmental  Law,  except  such as  could  not

authorities  and   self-regulatory   organizations  and  all  courts  and  other
tribunals,  including  without  limitation,  under any applicable  Environmental
Laws, as are necessary to own, lease,  license and operate its properties and to
conduct its business in the manner  described in the Offering  Circular,  except
for Authorizations  which the Company would not customarily  possess at the date
hereof but which will be obtained in the ordinary  course of  development of the
Riviera  Black  Hawk and those to be issued by any  Gaming  Authority  or Liquor
Licensing  Authority  which are necessary for the Company to own and operate the
Riviera Black Hawk. No such  Authorization  contains,  or will upon the issuance
thereof contain, a


                                       11



materially burdensome restriction.  Each such Authorization is valid and in full
force  and  effect  and the  Company  is in  compliance  with all the  terms and
conditions  thereof and with the rules and  regulations of the  authorities  and
governing bodies having jurisdiction with respect thereto. No event has occurred
(including,  without limitation, the receipt of any notice from any authority or
governing  body) which allows or,  after notice or lapse of time or both,  would
allow,  revocation,  suspension  or  termination  of any such  Authorization  or
results or,  after  notice or lapse of time or both,  would  result in any other
impairment  of the rights of the holder of any such  Authorization.  The Company
has no reason to believe  that any  governmental  body or agency is  considering
limiting,  suspending  or revoking  any such  Authorization.  The Company has no
reason to believe that any such Authorization  necessary in the future to own or
operate the Riviera Black Hawk in the manner described in the Offering Circular,
including without limitation,  any Gaming License or Liquor License, will not be
granted upon application (or,  alternatively,  that the necessity to obtain such
license, permit or approval will not be waived), or that any Gaming Authority or
Liquor Licensing Authority or any other governmental  agencies are investigating
the Company or related  parties,  other than in ordinary  course  administrative
reviews or any ordinary course review of the transactions contemplated hereby.

trade names  ("Intellectual  Property") to be employed by it in connection  with
the operation of its business in the manner described in the Offering  Circular,

Company has not received any notice of infringement of or conflict with asserted
rights of others with respect to any such Intellectual Property.

responsibility  against such losses and risks and in such amounts as are prudent
and customary in the  businesses  in which they are engaged.  The Company has no
reason  to  believe  that it will not be able to renew  its


                                       14

jurisdiction  have been filed,  other than those filings being contested in good
faith,  and all material  taxes,  including  withholding  taxes,  penalties  and

those being  contested in good faith and for which  adequate  reserves have been
provided.

     (ii)  The  contemplated  operation  and  use of  the  Riviera  Black  Hawk,
including the  construction of the Riviera Black Hawk, will be (giving effect to
any  waivers  or  variances  which  may be  obtained)  in  compliance  with  all
applicable municipal,  county, state and federal laws, regulations,  ordinances,
standards, orders, and other regulations,  where the failure to comply therewith
could have a Material  Adverse  Effect.  Under  applicable  zoning and use laws,
ordinances,  rules and  regulations,  the Riviera Black Hawk may be used for the
purposes contemplated in the Offering Circular, the Indenture and the Collateral
Documents,  and all necessary approvals have been obtained therefor,  except for

Black Hawk.

     (jj) Upon  execution and delivery of the Collateral  Documents  (other than
the Pledge  Agreement  and the Pledge and  Assignment  Agreement) by the parties
thereto and completion of the filings and recordings  contemplated  thereby, the
security interests created for the benefit of the Trustee and the holders of the

first priority security interests in the collateral subject thereto.

     (mm) The Initial  Purchaser has been furnished with a copy of the plans and
specifications  for the  construction  of the  improvements of the Riviera Black
Hawk and  other  necessary  expenditures.  Such  plans  and  specifications  are
satisfactory  to  the  Company.   The  anticipated  cost  of  such  improvements
(including interest,  legal,  architectural,  engineering,  planning, zoning and
other similar  costs) does not exceed the amounts for such costs set forth under
the caption "Use of Proceeds" in the Offering Circular. The Company is not aware
of any material  defects in such  improvements.  In addition,  each of the other
amounts set forth in the section entitled  "Sources and Uses of Funds" under the

9.   Indemnification

     (a)  The  Company  and  Riviera   Holdings   (collectively,   the  "Riviera
Entities"),  jointly and  severally,  agree to indemnify  and hold  harmless the
Initial  Purchaser,  its  directors,  its officers and each person,  if any, who
controls such Initial  Purchaser  within the meaning of Section 15 of the Act or
Section 20 of the  Exchange  Act,  from and against any and all losses,  claims,
damages, liabilities and judgments (including,  without limitation, any legal or
other  expenses  incurred in  connection  with  investigating  or defending  any
matter,  including any action, that could give rise to any such losses,  claims,
damages,  liabilities  or judgments)  caused by any untrue  statement or alleged
untrue statement of a material fact contained in the Final Offering Circular (or
any amendment or supplement  thereto),  the Preliminary Offering Circular or any
Rule 144A  Information  provided  by the  Company to any  holder or  prospective
purchaser  of Series A Notes  pursuant  to Section  5(i) hereof or caused by any
omission or alleged  omission to state  therein a material  fact  required to be
stated  therein or  necessary  to make the  statements  therein not  misleading,
except  insofar as such losses,  claims,  damages,  liabilities or judgments are
caused by any such untrue  statement or omission or alleged untrue  statement or
omission based upon information  relating to the Initial Purchaser  furnished in
writing to the Company by such Initial Purchaser.

     (b) The Initial Purchaser agrees to indemnify and hold harmless each of the
Riviera Entities,  and their respective  directors and officers and each person,
if any, who controls  (within the meaning of Section 15 of the Act or Section 20
of the  Exchange  Act) any of the  Riviera  Entities,  to the same extent as the
foregoing  indemnity from the Riviera Entities to the Initial


                                       20



Purchaser  but only  with  reference  to  information  relating  to the  Initial
Purchaser furnished in writing to the Company by the Initial Purchaser expressly
for use in the  Preliminary  Offering  Circular or the Final Offering  Circular,
which  includes  only the  first  sentence  of the  third  paragraph,  the third
sentence of the fourth paragraph and the fifth paragraph, in each case under the
caption  "Plan  of  Distribution"  appearing  of page 98 of the  Final  Offering
Circular.

     (c) In case any action shall be commenced  involving  any person in respect
of  which  indemnity  may be  sought  pursuant  to  Section  9(a) or  9(b)  (the
"indemnified  party"),  the  indemnified  party shall promptly notify the person
against whom such indemnity may be sought (the "indemnifying  party") in writing
and the  indemnifying  party shall assume the defense of such action,  including
the employment of counsel  reasonably  satisfactory to the indemnified party and
the payment of all fees and expenses of such counsel,  as incurred  (except that
in the case of any action in respect of which  indemnity may be sought  pursuant
to both Sections 9(a) and 9(b), the Initial  Purchaser  shall not be required to
assume the defense of such action  pursuant to this Section 9(c), but may employ
separate  counsel  and  participate  in the  defense  thereof,  but the fees and
expenses of such counsel,  except as provided below,  shall be at the expense of
the Initial  Purchaser).  Any  indemnified  party shall have the right to employ
separate counsel in any such action and participate in the defense thereof,  but
the fees and expenses of such counsel shall be at the expense of the indemnified
party unless (i) the  employment  of such counsel  shall have been  specifically
authorized in writing by the indemnifying  party,  (ii) the  indemnifying  party
shall  have  failed to  assume  the  defense  of such  action or employ  counsel
reasonably  satisfactory to the indemnified  party or (iii) the named parties to
any such action  (including any impleaded  parties) include both the indemnified
party and the  indemnifying  party,  and the  indemnified  party shall have been
advised by such counsel that there may be one or more legal  defenses  available
to it  which  are  different  from  or  additional  to  those  available  to the
indemnifying  party (in which  case the  indemnifying  party  shall not have the
right to assume the defense of such action on behalf of the indemnified  party).
In any such case, the  indemnifying  party shall not, in connection with any one
action or  separate  but  substantially  similar or related  actions in the same
jurisdiction  arising out of the same general  allegations or circumstances,  be
liable for the fees and expenses of more than one separate firm of attorneys (in
addition to any local counsel) for all indemnified parties and all such fees and
expenses shall be reimbursed as they are incurred. Such firm shall be designated
in writing by the  Initial  Purchaser,  in the case of the  parties  indemnified
pursuant to Section 9(a),  and by the Riviera  Entities,  in the case of parties
indemnified pursuant to Section 9(b). The indemnifying party shall indemnify and
hold harmless the indemnified party from and against any and all losses, claims,
damages, liabilities and judgments by reason of any settlement of any action (i)
effected with its written  consent or (ii) effected  without its written consent
if the  settlement  is entered  into more than  twenty  business  days after the
indemnifying  party shall have received a request from the indemnified party for
reimbursement  for the fees and expenses of counsel (in any case where such fees
and expenses  are at the expense of the  indemnifying  party) and,  prior to the
date of such settlement, the indemnifying party shall have failed to comply with
such  reimbursement  request.  No  indemnifying  party shall,  without the prior
written  consent of the indemnified  party,  effect any settlement or compromise
of, or  consent  to the entry of  judgment  with  respect  to,  any  pending  or
threatened  action in  respect of which the  indemnified  party is or could have
been a party and  indemnity  or  contribution  may be or could have been  sought
hereunder  by the  indemnified  party,  unless such  settlement,  compromise  or
judgment (i) includes


                                       21



an unconditional  release of the indemnified  party from all liability on claims
that are or could have been the subject  matter of such action and (ii) does not
include a statement as to or an admission of fault,  culpability or a failure to
act, by or on behalf of the indemnified party.

     (d) To the extent the  indemnification  provided  for in this  Section 9 is
unavailable to an indemnified  party or  insufficient  in respect of any losses,
claims,  damages,  liabilities  or  judgments  referred  to  therein,  then each
indemnifying  party,  in lieu of  indemnifying  such  indemnified  party,  shall
contribute to the amount paid or payable by such  indemnified  party as a result
of  such  losses,  claims,  damages,  liabilities  and  judgments  (i)  in  such
proportion as is  appropriate to reflect the relative  benefits  received by the
Company,  on the one hand, and the Initial  Purchaser on the other hand from the
offering  of the  Series A Notes or (ii) if the  allocation  provided  by clause
9(d)(i)  above is not  permitted by  applicable  law, in such  proportion  as is
appropriate  to reflect  not only the  relative  benefits  referred to in clause
9(d)(i) above but also the relative  fault of the Company,  on the one hand, and
the Initial  Purchaser,  on the other hand, in connection with the statements or
omissions  which  resulted  in such  losses,  claims,  damages,  liabilities  or
judgments, as well as any other relevant equitable considerations.  The relative
benefits received by the Company, on the one hand and the Initial Purchaser,  on
the other hand,  shall be deemed to be in the same  proportion  as the total net
proceeds from the offering of the Series A Notes (after  underwriting  discounts
and commissions, but before deducting expenses) received by the Company, and the
total  discounts and commissions  received by the Initial  Purchaser bear to the
total price to investors of the Series A Notes, in each case as set forth in the
table on the cover page of the  Offering  Circular.  The  relative  fault of the
Company, on the one hand, and the Initial Purchaser, on the other hand, shall be
determined by reference  to, among other  things,  whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state
a material fact relates to information supplied by the Company, on the one hand,
or the Initial  Purchaser,  on the other hand, and the parties' relative intent,
knowledge,  access to  information  and  opportunity  to correct or prevent such
statement or omission.

     (e) The Riviera Entities and the Initial  Purchaser agree that it would not
be just and equitable if  contribution  pursuant to Section 9(d) were determined
by pro rata allocation or by any other method of allocation  which does not take
account of the equitable considerations referred to in the immediately preceding
paragraph. The amount paid or payable by an indemnified party as a result of the
losses, claims, damages, liabilities or judgments referred to in the immediately
preceding  paragraph shall be deemed to include,  subject to the limitations set
forth above, any legal or other expenses  incurred by such indemnified  party in
connection  with  investigating  or defending any matter,  including any action,
that could  have given rise to such  losses,  claims,  damages,  liabilities  or
judgments.  Notwithstanding  the  provisions  of this  Section  9,  the  Initial
Purchaser shall not be required to contribute any amount in excess of the amount
by which the total discounts and commissions  received by such Initial Purchaser
exceeds the amount of any damages which the Initial Purchaser has otherwise been
required to pay by reason of such untrue or alleged untrue statement or omission
or alleged omission.  No person guilty of fraudulent  misrepresentation  (within
the meaning of Section 11(f) of the Act) shall be entitled to contribution  from
any person who was not guilty of such fraudulent misrepresentation.

     (f) The remedies provided for in this Section 9 are not exclusive and shall
not limit any  rights  or  remedies  which may  otherwise  be  available  to any
indemnified party at law or in


                                       22



equity.

not indicate the direction of the possible  change in, any rating of the Company
or any securities of the Company (including,  without limitation, the placing of
any of the  foregoing  ratings  on credit  watch  with  negative  or  developing
implications  or under review with an uncertain  direction)  by any  "nationally
recognized statistical rating organization" as such term is defined for purposes

nor shall  notice have been given of any  potential or intended  change,  in the
