         Collateral or an Excluded  Asset,  and (vii) other amounts from time to

agreements;  (iv) FF&E to the extent  financed or refinanced by, or the proceeds

Financing  and (B) Grantor is  permitted to enter into such FF&E  Financing  for
such FF&E under the Indenture;  and (v) any  Collateral  sold pursuant to a sale

instruments  reasonably  necessary  or  appropriate  to release the lien of this

does not apply to any of such Excluded  Assets;  provided  further that any such
FF&E Financing shall encumber only that FF&E  specifically  subject to such FF&E
Financing;  and provided  further that any such Excluded  Asset now or hereafter
acquired by Grantor shall  automatically  become part of the Collateral when and
to the extent it may  subsequently  be made  subject to such a lien  and/or such
approval is obtained  and/or such FF&E  Financing has been repaid,  satisfied or
terminated (as  applicable)  and/or such  Collateral sold pursuant to a sale and
leaseback transaction has been released.

SECTION 3.     Obligations.  This Agreement secures with respect to Grantor, and
the  Collateral  of  Grantor  is  collateral   security  for,  the  payment  and
performance  in full when due (whether at stated  maturity,  upon  redemption or
required  repurchase,  by acceleration or otherwise) of all obligations of every
type and nature of Grantor to the Trustee,  any other  trustee under the Deed of
Trust, or any Holder (including without limitation any and all amounts which may
at any time be or become due and payable and any and all interest accruing after
the maturity of the  Securities  and interest  accruing  after the filing of any
petition in bankruptcy, or the commencement of any insolvency, reorganization or

permitted by law, on the unpaid interest),  whether direct or indirect, absolute
or  contingent,  due or to become due, or now  existing or  hereafter  incurred,
which  may  arise  under,  out  of or in  connection  with  the  Indenture,  the
Securities,  the Completion Capital Commitment,  the Keep-Well  Agreement,  this
Agreement, the other Collateral Documents, or any other document made, delivered
or given by Grantor in connection with any of the foregoing  (collectively,  the
"Transaction Documents"), in each case whether on account of principal, premium,
interest,  fees, Liquidated Damages,  indemnities,  costs, expenses or otherwise
(including  without  limitation all reasonable fees and disbursements of counsel
(including without limitation in-house counsel) to the Trustee or to the Holders
that are required to be paid by Grantor  pursuant to the terms of the Indenture,
the Securities, the Completion Capital Commitment, the


                                       8

foregoing, collectively, the "Obligations").

SECTION 4.     Special Provisions Relating to Contracts

                  4.1  Grantor  Remains  Liable under Contracts. Anything herein
         to the contrary notwithstanding, Grantor shall remain liable under each
         of the  Contracts to which it is a party to observe and perform all the
         conditions  and   obligations  to  be  observed  and  performed  by  it
         thereunder,  all in  accordance  with the terms and  provisions of each
         such Contract, except as otherwise provided herein. Neither the Trustee
         (nor any other  trustee  under the Deed of Trust) nor any Holder  shall
         have any  obligation or liability  under any such Contract by reason of
         or arising out of this  Agreement or the receipt by the Trustee (or any
         such other  trustee) or any such Holder of any payment  relating to any
         such Contract pursuant hereto, nor shall the Trustee (or any such other
         trustee) or any Holder be obligated in any manner to perform any of the
         obligations  of Grantor under or pursuant to any Contract,  to make any
         payment, to make any inquiry as to the nature or the sufficiency of any
         payment  received by it or as to the  sufficiency of any performance by
         any party under any Contract, to present or file any claim, to take any
         action to enforce  any  performance  or to collect  the  payment of any
         amounts  which  may  have  been  assigned  to it or to  which it may be
         entitled at any time or times.

                  4.2. Communication with Contracting  Parties.  The Trustee, in
         its own name or in the name of others,  may,  (i) after the  occurrence
         and  continuance  of an Event of Default,  (ii) with the prior  written
         consent  of  Grantor  (which  shall  not be  unreasonably  withheld  or
         delayed)  or  (iii)  as  otherwise   permitted   under  the  Collateral
         Documents,  communicate  with  parties to the  Contracts to verify with
         them to the Trustee's  satisfaction the existence,  amount and terms of
         any Contract.

SECTION 5.     Maintenance of Perfected Security Interests; Further Assurances.

                  5.1. Perfection  Maintenance.  Grantor  agrees  that it  shall
         maintain the security  interests created by this Agreement as perfected
         first priority security interests, except with respect to (i) Permitted
         Liens and (ii) Collateral exclusively subject to a certificate of title
         statute and listed on Schedule A hereto, and shall defend such security
         interests against the claims and demands of all Persons whomsoever.

                  5.2. Further  Assurances.  At the Trustee's  request,  Grantor
         agrees  that at any time and from  time to time,  at the sole  cost and
         expense of Grantor,  Grantor shall  promptly,  and in any event,  in no
         less than ten (10) days, execute,  deliver and, where applicable,  file
         all further instruments and documents, including without limitation all
         financing,  continuation  or  amendment  statements  under the  Uniform
         Commercial Code in effect in any applicable  jurisdiction  with respect
         to the security  interests created hereby,  and take all further action
         that may be  necessary or that the Trustee may  reasonably  request for
         the purpose of obtaining,  maintaining  or preserving the full benefits
         of this Agreement and the rights and powers herein granted,  or for the
         purpose of creating, preserving, perfecting or otherwise protecting the
         liens and security  interests created or


                                       9





         purported  to be  created  hereby  and the  priority  thereof.  Without
         limiting  Grantor's  obligation  to make such filings,  Grantor  hereby
         authorizes the Trustee (subject to the following  sentence) to take all
         action  (including  without  limitation the filing of any UCC financing
         statements or continuation statements or amendments thereto without the
         signature  of Grantor as set forth in Section  15.4  hereof)  which the
         Trustee may deem necessary or desirable to perfect or otherwise protect
         the liens and  security  interests  created or  purported to be created
         hereunder and to obtain the benefits of this Agreement.  Subject to the
         Trustee's  obligations under the Indenture during the continuance of an
         Event of Default,  the Trustee shall not be responsible  for perfecting
         or maintaining  the perfection of any security  interest  granted to it
         under this Agreement or for filing, refiling, recording or re-recording
         any document,  financing statement,  notice or instrument in any public
         office at any time or times and shall not be responsible  for seeing to
         the  provision of insurance on or the payment of any taxes with respect
         to any  property  subject to this  Agreement.  In  accordance  with the
         Indenture,  in the event of an Asset Sale or an Event of Loss,  the Net
         Proceeds or the Net Loss Proceeds  thereof  shall be deposited  into an
         account,  if  reasonably  requested,  in  which,  at the  time  of such
         deposit,  the Trustee shall have a perfected  first  priority  security
         interest  and in  respect  of which  account  the  Trustee  shall  have
         received  an  Opinion  of Counsel  to  Grantor,  in form and  substance
         satisfactory  to the Trustee,  stating that the Trustee has a perfected
         first priority security interest in such account.

SECTION  6.    Representations,   Warranties  and   Covenants.   Grantor  hereby
represents  and warrants to, and covenants and agrees with, the Trustee (for the
benefit of the Trustee and the ratable benefit of the Holders), as follows:

                  6.1. Title;  No Other Liens.  Grantor is as of the date hereof
         and, as to  Collateral  acquired by it from time to time after the date
         hereof,  Grantor  shall be,  the owner of each  item of  Collateral  of
         Grantor (or in the case of Collateral held by Grantor as lessee under a
         lease or  licensee  under a license,  Grantor has and will have a valid
         and subsisting  leasehold interest or license,  as applicable,  in such
         Collateral), in each case free and clear from any and all Liens, claims
         or other right,  title or interest of any Person  other than  Permitted
         Liens.  No financing  statement or other public  notice with respect to
         all or any part of the Collateral is on file or of record in any public
         office,  except (a) financing statements related to Permitted Liens and
         (b) financing  statements which have been filed in favor of the Secured
         Parties  pursuant to this Agreement.  Without the prior written consent
         of the Trustee or as otherwise  expressly  permitted by the  Indenture,
         Grantor  will not in any way  encumber,  or  hypothecate,  or create or
         permit to exist, any lien, security interest,  charge or encumbrance or
         adverse  claim upon or other  interest  in the  collateral,  except for
         Permitted Liens, including without limitation encumbrances permitted by
         the Indenture and the liens created by this Agreement, and Grantor will
         defend the Collateral  against all claims and demands of all Persons at
         any time claiming the same or any interest  therein (other than holders
         of Permitted Liens), except as expressly provided herein.  Grantor will
         not  permit  any  notices  of Lien to exist or be on file in any public
         office with respect to all or any portion of the Collateral  except, in
         each case, for notices of Lien of holders of Permitted  Liens or except
         as may have been  filed by or for the  benefit of the  Secured  Parties
         relating to this Agreement or the other Transaction Documents.  Grantor
         shall


                                       10





         promptly  notify the Trustee of any  attachment  or other legal process
         levied against any of the Collateral  and any  information  received by
         Grantor  relative  to the  Collateral,  which may in any  material  way
         affect the value of the  Collateral  or the rights and  remedies of the
         Secured Parties in respect  thereof.  Except as expressly  permitted by
         the  Indenture,  Grantor will pay and discharge all taxes,  assessments
         and  governmental  charges or levies  against the  Collateral  prior to
         delinquency  thereof  and will keep the  Collateral  free of all unpaid
         claims and charges (including claims for labor, materials and supplies)
         whatsoever.

                  6.2. Perfected  First Priority Liens.  The security  interests
         granted  pursuant to this Agreement (a) constitute  perfected  security
         interests  in the  Collateral  in favor of the Trustee,  as  collateral
         security for the Obligations (other than Collateral exclusively subject
         to a certificate of title statute and listed on Schedule A hereto), and
         (b) are prior to all other Liens on the  Collateral in existence on the
         date hereof, other than Permitted Liens.

                  6.3. Necessary  Filings.   The   filings,   registrations  and
         recordings  described on Schedule B hereto constitute the only filings,
         registrations  and  recordings  necessary  or  appropriate  to  create,
         preserve, protect and perfect the security interests granted by Grantor
         to the Trustee pursuant to this Agreement in respect of the Collateral.
         All such filings,  registrations  and recordings have been accomplished
         as of the date hereof.

                  6.4. Other Financing  Statements. Grantor shall not execute or
         authorize or permit to be filed in any public  office or elsewhere  any
         financing statement (or similar statement or instrument of registration
         under the law of any jurisdiction)  relating to the Collateral,  except
         financing  statements  filed or to be filed (a) in respect of Permitted
         Liens  and  (b) in  favor  of the  Secured  Parties  pursuant  to  this
         Agreement.

                  6.5. Chief   Executive  Office;  Location  of  Collateral  and
         Records. Grantor's chief executive office is located at the address set
         forth for Grantor on Schedule C. Grantor  represents  and warrants that
         it has no place of business,  offices where  Grantor's books of account
         and records are kept, or places where the Collateral is used, stored or
         located,  and all  Collateral  is in its sole  possession  and control,
         except (i) as set forth on  Schedule C hereto,  and (ii)  except as set
         forth in Section 6.9. Grantor further covenants that it will not store,
         use or locate  any of the  Collateral  at any place  other  than as set
         forth on  Schedule C (or,  upon  forty-five  (45) days'  prior  written
         notice to the Trustee,  at such other location in a jurisdiction  where
         all action  required by Sections 5 and 6.6 (if  applicable)  shall have
         been taken).

                  6.6. Changes in Locations,  Name, etc.  Grantor represents and
         warrants that it currently  uses no business or trade names,  except as
         set forth on  Schedule  C hereto.  Grantor  shall  not (a)  change  the
         location of its chief executive  office from that specified in Schedule
         C, (b) change its name,  identity or corporate  structure or (c) change
         the  location  where  it  maintains  its  books  and  records  from the
         addresses  set forth on  Schedule C, unless (i) it shall have given the
         Trustee not less than forty-five (45) days' prior written notice of its
         intention  to do  so,  clearly  describing  such  new  location,  name,
         identity or corporate structure and providing such other information in
         connection  therewith as the Trustee may reasonably  request,  and (ii)
         with  respect  to  such  new  location,  name,  identity


                                       11





         or corporate  structure,  Grantor  shall have taken all action which is
         necessary  or  appropriate  or which  is  reasonably  requested  by the
         Trustee to maintain the perfection  and proof of the security  interest
         of the Trustee for the benefit of the Secured Parties in the Collateral
         intended to be granted  hereby and shall have  delivered to the Trustee
         an Officer's Certificate as to compliance with this clause (ii).

                  6.7. Delivery of Instruments,  Investment Property and Chattel
         Paper.  If any amount  payable under or in  connection  with any of the
         Collateral,  or any Collateral itself,  shall be or become evidenced by
         any Instrument,  Investment Property or Chattel Paper, such Instrument,
         Investment Property or Chattel Paper shall be promptly delivered to the
         Trustee,  duly endorsed in a manner  satisfactory to the Trustee, to be
         held as  Collateral  pursuant to this  Agreement  (except as  otherwise
         specifically  provided in the Pledge and  Assignment  Agreement and the
         Cash Collateral and Disbursement Agreement).

                  6.8. Information   and Inspection.  Upon reasonable  notice to
         Grantor,  Grantor  shall (a) allow the  Trustee to inspect and copy all
         records  relating to the Collateral and the Obligations and (b) furnish
         to the Trustee such  information as the Trustee may reasonably  request
         from time to time with  respect to the  Collateral,  any  distributions
         thereon and any proceeds thereof.

                  6.9. Location  of  Equipment.  All Equipment  held on the date
         hereof by Grantor is located at one of the locations  shown for Grantor
         on  Schedule  C. All  Equipment  now held or  subsequently  acquired by
         Grantor shall be kept at one or more of the locations shown for Grantor
         on Schedule C hereto,  or such new location as Grantor may establish if
         (a) it shall have given to the Trustee at least  forty-five  (45) days'
         prior written notice of its intention to do so, clearly describing such
         new  location  and  providing  such  other  information  in  connection
         therewith as the Trustee may reasonably  request,  and (b) with respect
         to such new  location,  Grantor  shall have  taken all action  which is
         necessary  or  appropriate  or which  is  reasonably  requested  by the
         Trustee  to  maintain  the  perfection  and  priority  of the  security
         interest of the  Trustee for the benefit of the Secured  Parties in the
         Collateral  granted or  purported  to be granted  hereby and shall have
         delivered to the Trustee an Officer's Certificate as to compliance with
         this  clause  (b).  Schedule A contains a true,  complete  and  correct
         listing of all of the motor  vehicles  and other  Equipment  of Grantor
         subject to a certificate of title statute in any  jurisdiction  and the
         jurisdiction  in which such  Collateral is subject to a certificate  of
         title statute.

                  6.10.Copyrights, Patents and Trademarks.

         subsisting,  unexpired,  enforceable  and has not



                                       12





         been   cancelled  or  abandoned;  (vi)  except as  set  forth in any of
         Exhibit A, Exhibit B or Exhibit C, none of such Copyrights, Patents and
         Trademarks  set forth  therein is on the date hereof the subject of any
         licensing  or  franchise  agreement  pursuant  to which  Grantor is the
         licensor or franchisor (except as set forth on Exhibit D); (vii) to the
         best of Grantor's knowledge after due inquiry, no holding,  decision or
         judgment has been rendered by any  Governmental  Authority  which would
         limit,  cancel or question  the  validity of any  Copyright,  Patent or
         Trademark  in any respect that could  reasonably  be expected to have a
         Material Adverse Effect; and (viii) to the best of Grantor's  knowledge
         after due  inquiry,  no action or  proceeding  is  pending  on the date
         hereof (x)  seeking to limit,  cancel or question  the  validity of any
         Copyright,  Patent or Trademark, or (y) which, if adversely determined,
         could  reasonably  be expected  have a Material  Adverse  Effect on the
         value of any Copyright, Patent or Trademark.

                           (b) Grantor  (either  itself or through  licensees or
         sublicensees)  will (i) continue to use each material  Trademark to the
         extent it has  rights  to such  Trademark  on each and every  trademark
         class of goods or services  applicable to its current line as reflected
         in its current catalogs, brochures and price lists, if any, in order to
         maintain  such   Trademark  in  full  force  free  from  any  claim  of
         abandonment  for non-use,  (ii)  maintain as in the past the quality of
         products and services  offered under such Trademark,  (iii) employ each
         material  Trademark with the appropriate  notice of registration,  (iv)
         not adopt or use any mark which is  confusingly  similar or a colorable
         imitation of such Trademark unless the Trustee, for the ratable benefit
         of the  Holders,  shall  obtain a  perfected  first  priority  security
         interest in such mark pursuant to this  Agreement,  and (v) not do (and
         not  permit  any  licensee  or  sublicensee  thereof  to do) any act or
         knowingly  omit to do any act whereby such  Trademark may reasonably be
         expected to become  invalidated  unless the Grantor  determines  in its
         prudent  business  judgment that such  Trademark is no longer useful in
         the operation of its business.

                           (c) Grantor  will  not do any act,  or omit to do any
         act,  whereby  any Patent may become  abandoned  or  dedicated  if such
         abandonment or dedication  could reasonably be expected have a Material
         Adverse Effect.

                           (d) Grantor will notify the Trustee immediately if it
         knows,  or has reason to know,  that any  application  or  registration
         relating to any material  Patent or Trademark  may become  abandoned or
         dedicated,  or of any adverse  determination or development  (including
         without  limitation the  institution of, or any such  determination  or
         development  in,  any  proceeding  in  the  United  States  Patent  and
         Trademark  Office or any court or  tribunal in any  country)  regarding
         Grantor's ownership of any Patent or Trademark material to the business
         of Grantor or its right to  register  the same or to keep and  maintain
         the same and of any action Grantor is taking in respect of such event.

                           (e) Whenever Grantor, either by itself or through any
         agent,  employee,  licensee or designee,  shall file an application for
         the  registration  of any Patent or  Trademark  with the United  States
         Patent  and  Trademark  Office or any  similar  office or agency in any
         other  country or any  political  subdivision  thereof,  Grantor  shall
         report  such filing to the  Trustee  within  thirty (30) days after the
         last day of the fiscal  quarter in which


                                       13





         such  filing  occurs.  Grantor  shall  execute  and deliver any and all
         agreements,  instruments,  documents, and papers as may be necessary or
         appropriate  or as the  Trustee  may  reasonably  request to  evidence,
         perfect  and/or  maintain  the  perfection  of the  Trustee's  and  the
         Holders'  security interest in any Patent or Trademark and the goodwill
         and general  intangibles  of Grantor  relating  thereto or  represented
         thereby and shall deliver to the Trustee an Officer's Certificate as to
         compliance with this subparagraph (e).

                           (f) Consistent  with  Grantor's  reasonable  business
         judgment,  Grantor  will  take  all  reasonable  and  necessary  steps,
         including without limitation in any proceeding before the United States
         Patent and  Trademark  Office,  or any similar  office or agency in any
         other country or any political  subdivision thereof, as applicable,  to
         maintain  and  pursue  each  application  (and to obtain  the  relevant
         registration)  and to  maintain  each  registration  of the Patents and
         Trademarks  material  to the  business of  Grantor,  including  without
         limitation  filing of applications  for renewal,  affidavits of use and
         affidavits  of  incontestability  and,  as to  Patents,  the payment of
         maintenance  fees,  except  where the failure to take such action could
         not have a Material Adverse Effect.

                           (g) In the event  that any  Patent  or  Trademark  is
         infringed,   misappropriated   or  diluted  by  a  third  party,  which
         infringement, misappropriation or dilution could reasonably be expected
         to have a  Material  Adverse  Effect,  Grantor  shall  upon  receipt of
         knowledge of such infringement,  misappropriation or dilution, promptly
         (i) take such  actions as Grantor  shall  reasonably  deem  appropriate
         under the circumstances to protect such Patent or Trademark and (ii) if
         such Patent or Trademark is of material economic value, promptly notify
         the Trustee  after it learns  thereof and,  consistent  with  Grantor's
         reasonable business judgment, sue for infringement, misappropriation or
         dilution,  seek injunctive relief where appropriate and recover any and
         all damages for such infringement, misappropriation or dilution.

                           (h) Grantor  (either  itself or through  licensees or
         sublicensees)  will (i) employ the appropriate  notice of copyright for
         each  published  Work  subject to  copyright  protection  to the extent
         necessary to protect the  Copyright  relating to such Work and (ii) not
         do (and not permit any licensee or  sublicensee  thereof to do) any act
         or  knowingly  omit to do any act whereby any  material  Copyright  may
         become  invalidated,  except  where the failure to take any such action
         could not reasonably be expected to have a Material Adverse Effect.

                           (i) Grantor  will  not  (either   itself  or  through
         licensees)  do any act,  or omit to do any act,  whereby  any  material
         Copyright may reasonably be expected to become injected into the public
         domain,  except  where the  failure to take any such  action  could not
         reasonably be expected to have a Material Adverse Effect.

                           (j) Grantor will notify the Trustee immediately if it
         knows,  or has reason to know,  that any Copyright may become  injected
         into the public domain or of any adverse  determination  or development
         (including   without   limitation  the  institution  of,  or  any  such
         determination  or  development  in,  any  proceeding  in any  court  or
         tribunal in any


                                       14





         country)  regarding  Grantor's  ownership of any such  Copyright or its
         validity and of any action Grantor is taking in respect of such event.

                           (k) Whenever Grantor, either by itself or through any
         agent,  employee  licensee,  sublicensee  or  designee,  shall  file an
         application  for the  registration  of any  Copyright  with the  United
         States  Copyright  Office or any similar office in any other country or
         political subdivision thereof,  Grantor shall report such filing to the
         Trustee  within  thirty  (30)  days  after  the last day of the  fiscal
         quarter in which such filing occurs.  Grantor shall execute and deliver
         any and all agreements,  instruments,  documents and papers as shall be
         necessary or  appropriate  or as the Trustee  reasonably may request to
         evidence,  perfect and/or  maintain the perfection of the Trustee's and
         the Holders'  security  interest in such Copyright and shall deliver to
         the  Trustee  an  Officer's  Certificate  as to  compliance  with  this
         subparagraph (k).

                           (l) Consistent with the Grantor's reasonable business
         judgment,  Grantor  will take all  reasonable  and  necessary  steps in
         accordance with its reasonable business judgment to maintain and pursue
         each  application  (and to obtain  the  relevant  registration)  and to
         maintain  to the  extent  permitted  by law each  registration  of each
         material Copyright owned by Grantor including without limitation filing
         of applications for renewal, where necessary.

                           (m) Grantor  will promptly  notify the Trustee of any
         material  infringement  of any  Copyright  owned by it of which Grantor
         becomes aware and which  infringement  could  reasonably be expected to
         have a Material  Adverse  Effect,  and  Grantor  shall upon  receipt of
         knowledge of such  infringement  take all actions it  reasonably  deems
         appropriate   under  the   circumstances  to  protect  such  Copyright,
         including,  where appropriate,  the bringing of suit or the settling of
         actual or potential suits for infringement,  seeking  injunctive relief
         and seeking to recover any and all damages for such infringement.

                  6.11. Authorization, Enforceability. Grantor has the requisite
         power,  authority  and legal right to grant a security  interest in all
         the  Collateral  of  Grantor  pursuant  to  this  Agreement,  and  this
         Agreement  has been duly  authorized,  executed and  delivered  by, and
         constitutes  the  legal,  valid  and  binding  obligation  of  Grantor,
         enforceable against Grantor in accordance with its terms. Each Contract
         to which Grantor is a party is in full force and effect and constitutes
         a valid and legally  enforceable  obligation of Grantor,  except as the
         enforceability  thereof  may  be  limited  by  bankruptcy,  insolvency,
         fraudulent  conveyance,  reorganization,  moratorium  and other similar
         laws relating to or affecting creditors' rights generally or by general
         equitable  principles  (whether considered in a proceeding in equity or
         at law).

                  6.12. No  Consents. Except for the filings,  registrations and
         recordings  contemplated  in  Section  6.3,  no  consent  of any Person
         (including without limitation any stockholders or creditors of Grantor)
         and no consent,  authorization,  approval,  or other  action by, and no
         notice to or filing with, any Governmental Authority or regulatory body
         or other  Person is required (a) for the grant by Grantor of a security
         interest  in the  Collateral  pursuant to this  Agreement,  (b) for the
         perfection or maintenance  of such


                                       15





         security  interest created hereby,  including the first priority nature
         of such  security  interest,  or the  exercise  of rights and  remedies
         provided  for  herein,  (c) for  the  enforceability  of such  security
         interest against third parties,  including judgment lien creditors, (d)
         for the  authorization,  execution,  delivery  or  performance  of this
         Agreement  by  Grantor,  or (e) for the  exercise by the Trustee of the
         remedies in respect of the Collateral pursuant to this Agreement.

                  6.13. Collateral. All information set forth herein  (including
         without  limitation  the  information  set forth in the  Schedules  and
         Exhibits  annexed  hereto,  as they may be  amended  from time to time)
         relating to the  Collateral  is accurate  and  complete in all material
         respects.

                  6.14. Ownership  and  Control  of  Collateral.  Except  as may
         otherwise be permitted by the  Indenture,  Grantor at all times will be
         the sole  legal and  beneficial  owner or lessee of the  Collateral  of
         Grantor.

                  6.15. [Intentionally Omitted].

                  6.16.    Representations Regarding Contracts.

                           (a) Each  Contract to which  Grantor is a party is in
         full force and effect and  constitutes a valid and legally  enforceable
         obligation  of  Grantor,  except as the  enforceability  thereof may be
         limited   by    bankruptcy,    insolvency,    fraudulent    conveyance,
         reorganization,  moratorium  and  other  similar  laws  relating  to or
         affecting   creditors'   rights  generally  or  by  general   equitable
         principles (whether considered in a proceeding in equity or at law).

                           (b) Except  as could not  reasonably  be  expected to
         have a Material  Adverse  Effect,  Grantor or (to the best of Grantor's
         knowledge)  any other party to any Contract to which Grantor is a party
         is not in default in the  performance or observance of any of the terms
         thereof and Grantor is not aware of any fact that, with notice or lapse
         of time, could reasonably be expected to result in such a default.

                           (c) Except  as could not  reasonably  be  expected to
         have a Material Adverse Effect,  Grantor has fully performed all of its
         obligations required as of the date hereof under each Contract to which
         Grantor is a party.

                           (d) No defense,  offset,  counterclaim or claim which
         could  reasonably be expected to (i)  materially  adversely  affect the
         value of the  Contract  to  which  it  relates  as  Collateral  or (ii)
         otherwise  have a Material  Adverse Effect has been asserted or alleged
         against Grantor as to any Contract to which Grantor is a party.

                           (e) No amount constituting  Collateral and payable to
         Grantor under or in connection  with any Contract to which Grantor is a
         party is  evidenced  by any  Instrument,  Chattel  Paper or  Investment
         Property which has not been delivered to the Trustee.


                                       16





                           (f) None   of  the  parties  to  any  Contract  is  a
         Governmental Authority except as set forth on Schedule D.

                  6.17. Covenants Regarding Contracts.

                           (a) Grantor  shall perform and comply in all material
         respects with all its obligations  under the Contracts to which Grantor
         is a party where failure to comply,  individually  or in the aggregate,
         would have a Material Adverse Effect.

                           (b) Except as expressly  permitted by the  Indenture,
         the Cash Collateral and Disbursement  Agreement or any other Collateral
         Document,  Grantor  shall not  amend,  modify,  terminate  or waive any
         provision  of any  Contract  to which  Grantor is a party in any manner
         which could  reasonably be expected to materially  adversely affect the
         value  of  such  Contract  as  Collateral  or  which  could   otherwise
         reasonably  be expected  to have a Material  Adverse  Effect;  provided
         that,  except  as  otherwise  required  under the Cash  Collateral  and
         Disbursement  Agreement,  Grantor may replace a Contract  (the "Initial
         Contract") so long as the contract  entered into to replace the Initial
         Contract  (the  "Replacement  Contract")  is  subject  to the  security
         interest created by this Agreement.

                           (c) Except as expressly  permitted by the  Indenture,
         Grantor shall exercise  promptly and diligently each and every material
         right which it may have under each  material  Contract to which Grantor
         is a party; provided that Grantor may amend, modify, terminate or waive
         rights subject to Section 6.17(b) above.

                           (d) Except as expressly permitted by the Indenture or
         any other Collateral  Document,  Grantor shall deliver to the Trustee a
         copy of each  material  demand,  notice  of  default  or other  written
         material  notification  received  by it  relating  in  any  way  to any
         material Contract to which Grantor is a party.

                           (e) Except as expressly  permitted in the  Indenture,
         in any  suit,  proceeding  or  action  brought  by or on  behalf of the
         Trustee  under  any  Contract  to which  Grantor  is a party  which the
         Trustee is entitled  to bring  after an Event of Default has  occurred,
         Grantor  will  defend,  save,  indemnify  and keep the  Trustee and the
         Holders harmless from and against any and all expenses, losses, claims,
         liabilities  and  damages,  as  incurred,  suffered  by  reason  of any
         defense,  setoff,  counterclaim,  recoupment  or reduction or liability
         whatsoever  of the  obligor  thereunder,  arising  out of a  breach  by
         Grantor  of any  obligation  thereunder  or  arising  out of any  other
         agreement,  indebtedness  or liability at any time owing to or in favor
         of such  obligor or its  successors  from  Grantor;  provided  that the
         indemnity  provided  under this Section  6.17(e) shall not apply to the
         extent  such  liability  arises  from the gross  negligence  or willful
         misconduct of the Trustee or Holders.

                           (f) The covenants  set forth at Sections  6.17(a) and
         (c) shall  terminate  on, and be of no further force or effect from and
         after,  the date  that  the  Riviera  Black  Hawk  (as  defined  in the
         Indenture) is Operating (as defined in the Indenture).


                                       17





                  6.18. Further Actions and Identification of Collateral. At any
         time upon the  occurrence of an Event of Default,  or otherwise no more
         than two times in any twelve-month  period,  Grantor shall, at its sole
         cost and expense,  make,  execute,  endorse,  acknowledge,  file and/or
         deliver to the Trustee from time to time such lists,  descriptions  and
         designations  of  the  Collateral  of  Grantor,   copies  of  warehouse
         receipts,  receipts  in the  nature  of  warehouse  receipts,  bills of
         lading,  documents of title, vouchers,  invoices and schedules relating
         to the Collateral of Grantor,  as the Trustee may  reasonably  request,
         all in reasonable  detail.  Grantor will promptly notify the Trustee in
         writing of any event, or change of law, regulation,  business practice,
         or  business  condition  of which  Grantor  has  knowledge  that  could
         reasonably be expected to materially  adversely affect the value of the
         Collateral.

                  6.19. Records of Collateral;  Notation  on Books and  Records.
         Grantor shall keep full and accurate books and records  relating to the
         Collateral  of  Grantor,  and stamp or  otherwise  mark such  books and
         records  in such  manner  as may be  necessary  or as the  Trustee  may
         reasonably  require in order to reflect the security  interests granted
         by this Agreement.

                  6.20.  Notices. Grantor shall promptly  notify the Trustee, in
         reasonable  detail, of any Lien (other than security  interests created
         hereby or Permitted  Liens) or any  attachment  or other legal  process
         levied against any of the Collateral  and any  information  received by
         the Grantor  relative to the Collateral,  which may in any material way
         affect the value of the  Collateral  or the rights and  remedies of the
         Secured Parties in respect thereof.

                  6.21. Collateral Maintenance.  Grantor shall keep and maintain
         the Collateral in good operating  condition,  working order and repair,
         ordinary  wear and tear  excepted,  and from  time to time will make or
         cause to be made all repairs,  replacements  and other  improvements in
         connection  therewith that are necessary or desirable  toward such end.
         Grantor shall not misuse or abuse the Collateral,  or waste or allow it
         to deteriorate, except for the ordinary wear and tear of its normal and
         expected  use  in  Grantor's  business  in  accordance  with  Grantor's
         policies  as then in  effect  (provided  that no  changes  are  made to
         Grantor's  policies  as in  effect  on the date  hereof  that  would be
         materially adverse to the interests of any of the Secured Parties), and
         Grantor shall comply with all laws, statutes and regulations pertaining
         to the use or ownership of the Collateral where failure to comply could
         reasonably be expected to result in a Material Adverse Effect.

                  6.22. After-Acquired Intellectual Property.  If  Grantor shall
         (a) obtain any ownership  rights to any new  invention  (whether or not
         patentable),   know-how,  trade  secret,  design,  process,  procedure,
         formula,   diagnostic   test,   service  mark,   trademark,   trademark
         registration,  trade name, copyright or license, or (b) become entitled
         to the benefit of any patent,  service mark or  trademark  application,
         trademark,  trademark registration,  license renewal, copyright renewal
         or  extension,  or  patent  for any  reissue,  division,  continuation,
         renewal  extension,  or  continuation-in-part  of  any  patent  or  any
         improvement  on any  patent,  excluding  as to (a) and  (b) any  right,
         interest  or  benefit  received  by  Grantor  which by the terms of any
         agreement  exclusively  conferring  such  right,  interest  or  benefit
         prohibits the granting by Grantor of a security interest  therein,  the


                                       18





         provisions of this Agreement shall  automatically apply thereto and any
         item   enumerated  in  clause  (a)  or  (b)  of  this  sentence   shall
         automatically  constitute  Collateral  and  shall  be  subject  to  the
         assignment,  lien and security  interest created hereby without further
         action by any party.  Grantor  promptly  shall (i) give to the  Trustee
         written  notice  of its  acquisition  of or  entitlement  to any of the
         rights subject to federal  registration set forth in clauses (a) or (b)
         of the immediately  preceding  sentence and (ii) confirm the attachment
         of the lien and security  interest created hereby to any of such rights
         by  execution  of an  appropriate  instrument  delivered to the Trustee
         and/or to make such  recordings  and  filings  as may be  necessary  or
         appropriate  or as the  Trustee  may  reasonably  request to  evidence,
         confirm,  perfect  and/or  maintain  the  perfection  of such  security
         interest, including without limitation an amendment to Exhibits A, B, C
         and D (as  applicable)  to  include  any such  rights  and  appropriate
         filings with the applicable federal office.

SECTION 7.     Special Provisions Relating to Intellectual Property.

                  7.1. Modifications.  Grantor  and the Trustee may modify  this
         Agreement, without the consent of Holders, by amending Exhibits A, B, C
         and/or D to include  any  future  Intellectual  Property  of Grantor in
         accordance  with  Section  6.10  or  Section  6.22  or to  reflect  any
         disposition  of  Intellectual  Property  made in  compliance  with  the
         provisions of this Agreement and the Indenture.

                  7.2. Applications.  Except in  the ordinary course of business
         consistent  with  prudent  business  practice  or as  Grantor,  in  its
         reasonable business judgment,  deems appropriate or as may otherwise be
         permitted by the Indenture,  Grantor shall not abandon any registration
         of any  Intellectual  Property or any right to file an application with
         respect to  Intellectual  Property or any pending  application,  unless
         refused  by  the  Patent  and  Trademark  Office  Examiner  where  such
         abandonment,  in each case,  could  reasonably  be  expected  to have a
         Material  Adverse  Effect,  without  the prior  written  consent of the
         Trustee.

                  7.3. Restriction on Licensing  Intellectual Property.  Grantor
         shall not license the Intellectual  Property or any portion thereof, or
         amend or permit the amendment of any of the Licenses, in either case in
         a manner  that  adversely  affects  the right to receive  any  material
         amount of payments  thereunder or, except as otherwise  permitted under
         the Indenture, in any manner materially adverse to the interests of the
         Trustee in the  Intellectual  Property,  in each case without the prior
         written consent of the Trustee.

                  7.4. Use of  Intellectual Property  Prior to Event of Default.
         Subject to Section 7.3 but  notwithstanding  any other provision herein
         to the contrary, so long as no Event of Default shall have occurred and
         be  continuing,  Grantor  shall be  permitted to exploit,  use,  enjoy,
         protect,  license,  sublicense,  assign,  sell,  dispose of or take any
         other actions with respect to the Intellectual Property in the ordinary
         course of the  business  of Grantor  or in the  exercise  of  Grantor's
         reasonable business judgment.  In furtherance of the foregoing,  unless
         an Event of Default shall have occurred and be continuing,  the Trustee
         shall,  from time to time upon the  request  of  Grantor,  execute  and
         deliver to Grantor any instruments, certificates or other documents, in
         the  form  so  requested,   which  Grantor  shall  have


                                       19





         certified are appropriate to allow Grantor to take any action permitted
         above  (including  relinquishment  of the  license  provided  as to any
         specific Intellectual Property).

SECTION 8.     Transfers and Other Liens. Except as permitted by the  Indenture,
Grantor  shall not sell,  convey,  assign or otherwise  dispose of, or grant any
option  with  respect  to, any of the  Collateral.  Grantor  shall not create or
permit to exist any Lien upon or with  respect  to any of the  Collateral  other
than Permitted Liens or Liens in favor of the Secured  Parties  pursuant to this
Agreement.

SECTION 9.     Reasonable Care. Beyond the duties set forth in  Section 15.3 and
the exercise of reasonable  care in custody  thereof,  the Trustee shall have no
duty as to the  collection of any  Collateral in its possession or control or in
the possession or control of any agent or nominee of the Trustee,  or any income
thereon or as to the  preservation  of rights against prior parties or any other
rights  pertaining  thereto.  The  Trustee  shall be  deemed  to have  exercised
reasonable  care  in the  custody  and  preservation  of the  Collateral  in its
possession if such Collateral is accorded treatment substantially  equivalent to
that which the Trustee, in its individual capacity, accords its own property, it
being understood that the Trustee shall not have  responsibility  for taking any
necessary  steps to  preserve  rights  against  any Person  with  respect to any
Collateral.

SECTION 10.    Remedies Upon Event of Default.

                  10.1. Notice to Obligors and Contract Parties.  At any time

         after  the  occurrence  and  during  the  continuance  of an  Event  of
         Default,  the Trustee may,  and, if requested by  the Trustee,  Grantor
         shall,  notify parties to the Contracts and account debtors  in respect
         of any General  Intangibles or Accounts  constituting  Collateral  that
         such  Collateral  has been  assigned  to the  Trustee  for the  ratable
         benefit of the Holders and that  payments in respect  thereof  shall be
         made directly to the Trustee.

                  10.2.  Proceeds to be Turned Over to  Trustee.  If an Event of
         Default shall have occurred and be continuing, all amounts and proceeds
         (including   instruments)   received  by  Grantor  in  respect  of  any
         Collateral  shall be held by Grantor in trust for the  Trustee  and the
         Holders,  segregated from other funds of Grantor, and shall,  forthwith
         upon  receipt by  Grantor,  be turned  over to the Trustee in the exact
         form received by Grantor (duly  endorsed by Grantor to the Trustee,  if
         required  or  requested)  and  held by the  Trustee  in the  Collateral
         Account,  which shall be maintained under the sole dominion and control
         of  the  Trustee.  All  Proceeds  while  held  by  the  Trustee  in the
         Collateral  Account  (or by  Grantor in trust for the  Trustee  and the
         Holders) shall  continue to be held as collateral  security for all the
         Obligations  and shall not constitute  payment thereof until applied as
         provided in Section 11.

                        10.3.  Obtaining Possession of theCollateral.If an Event
         of  Default shall have occurred  and be  continuing,  then and in every
         such case, the Trustee may, but shall not be obligated to, in  addition
         to any other action permitted by law (and not limited in any manner  to
         the remedies contained in the Securities and the Indenture) take one or
         more of the following actions:


                                       20




                           (a) personally,   or   by    agents   or   attorneys,
         immediately take possession of the Collateral or any part thereof, from
         Grantor  or any  other  Person  who  then  has  possession  of any part
         thereof, with or without notice or process of law, and for that purpose
         may  enter  upon  Grantor's  premises  where any of the  Collateral  is
         located  and remove such  Collateral  and use in  connection  with such
         removal any and all services,  supplies,  aids and other  facilities of
         Grantor;

                           (b) sell,  assign  or  otherwise liquidate, or direct
         Grantor to sell, assign or otherwise liquidate,  any or all investments
         made in whole or in part with the  Collateral or any part thereof,  and
         take  possession  of the  proceeds  of any  such  sale,  assignment  or
         liquidation; and

                           (c) take  possession  of  the Collateral  or any part
         thereof by  directing  Grantor  in  writing to deliver  the same to the
         Trustee  at any place or  places  which the  Trustee  shall  reasonably
         select, in which event Grantor shall at its own expense:  (i) forthwith
         cause the same to be moved to the place or places so  designated by the
         Trustee and there  delivered  to the  Trustee;  (ii) store and keep any
         Collateral so delivered to the Trustee at such place or places  pending
         further action by the Trustee;  and (iii) while the Collateral shall be
         so stored and kept,  provide  such guards and  maintenance  services as
         shall be  reasonably  necessary to protect the same and to preserve and
         maintain them in good  condition.  Grantor's  obligation to deliver the
         Collateral is of the essence of this Agreement.  Upon  application to a
         court of equity having  jurisdiction,  the Trustee shall, to the extent
         permitted  by  law,  be  entitled  to  a  decree   requiring   specific
         performance by Grantor of such obligation.

                  10.4. Use and Preservation of the Collateral.  Upon and during
         the  existence  of an Event of Default,  the  Trustee  may, in its sole
         discretion,  use or manage the Collateral to preserve the Collateral or
         its  value,  or  to  pay  the  Obligations   which  includes,   without
         limitation,  the right to take  possession  of  Grantor's  premises and
         property,  to exclude  Grantor  and any third  parties  (whether or not
         claiming  under  Grantor)  from such  premises  and  property,  to make
         repairs,  replacements,  alterations,  additions and improvements to or
         take any acts to preserving  the  Collateral,  and to dispose of all or
         any portion of the Collateral.

                  10.5. Remedies under UCC.   In  addition  to  the  rights  and
         remedies  provided in this Agreement or otherwise  available to it, the
         Trustee shall have all the rights and remedies of a secured party under
         the UCC or under the  Uniform  Commercial  Code of any  other  relevant
         jurisdiction.

                  10.6.  Additional Remedies. Upon the occurrence and during the
         continuance  of an Event of Default,  the  Trustee,  without  demand of
         performance or other demand,  presentment,  protest,  advertisement  or
         notice of any kind  (except  any notice  required  by law  referred  to
         below) to or upon  Grantor or any other  person  (all and each of which
         demands,  defenses,  advertisements  and  notices  are,  to the  extent
         permitted by law, hereby waived),  may in such circumstances  forthwith
         collect,  receive,  appropriate and realize upon the Collateral, or any
         part thereof,  and/or may forthwith sell, lease, assign, give


                                       21





         option or options to purchase,  or otherwise dispose of and deliver the
         Collateral  or  any  part  thereof  (or  contract  to  do  any  of  the
         foregoing),  in one or more parcels at public or private sale or sales,
         at any exchange,  broker's  board or office of the Trustee or elsewhere
         upon such terms and conditions as the Trustee may deem advisable and at
         such  prices  as it may  elect,  for cash or on  credit  or for  future
         delivery  without  assumption  of any credit  risk.  The Trustee or any
         Holder shall have the right,  to the extent  permitted by law, upon any
         such public sale or sales or upon any such  private  sale or sales,  to
         purchase for cash the whole or any part of the  Collateral so sold (but
         any  such  purchase  may not,  in  whole or in part,  be in the form of
         cancellation  of  indebtedness  without  the  consent of each  Holder).
         Grantor  further  agrees,  at the  Trustee's  request,  to assemble the
         Collateral  of Grantor and make it  available  to the Trustee at places
         which  the  Trustee  shall  reasonably  select,  whether  at  Grantor's
         premises or elsewhere.  The Trustee shall apply the net proceeds of any
         action  taken by it pursuant to this  Agreement,  after  deducting  all
         reasonable  costs and expenses of every kind incurred by the Trustee in
         connection therewith or incidental to the care or safekeeping of any of
         the  Collateral or in any way relating to the  Collateral or the rights
         of the Trustee and the Holders hereunder,  including without limitation
         reasonable attorneys' fees and disbursements, as provided in Section 11
         hereof,  and only after such  application  and after the payment by the
         Trustee of any other amount required by any provision of law, including
         without  limitation  Section  9-504(1)(c)  of the UCC, need the Trustee
         account for the surplus, if any, to Grantor. To the extent permitted by
         law,  Grantor  waives all  claims,  damages  and demands it may acquire
         against the Trustee (or any other  trustee  under the Deed of Trust) or
         any Holder  arising  out of the  exercise  by any of them of any rights
         hereunder.  If any  notice of  proposed  sale or other  disposition  of
         Collateral  shall be required by law, such notice shall,  to the extent
         permitted by law, be deemed reasonable and proper if given at least ten
         (10) days before such sale or other  disposition.  Notwithstanding  the
         foregoing,  the  Trustee  shall  not be  obligated  to make any sale of
         Collateral  regardless of notice of sale having been given. The Trustee
         may, without notice or publication, adjourn any public or private sale,
         or cause the same to be adjourned from time to time by  announcement at
         the time and place fixed for sale or, with  respect to a private  sale,
         after  which such sale may take place,  and any such sale may,  without
         further  notice,  be made at the  time  and  place  to  which it was so
         adjourned or, with respect to a private sale, after which such sale may
         take place.  Each  purchaser  at any such sale shall hold the  property
         sold free from any claim or right on the part of  Grantor,  and Grantor
         hereby  waives,  to the full  extent  permitted  by law,  all rights of
         redemption,  stay and/or  appraisal which Grantor now has or may at any
         time in the future have under any rule of law or statute  now  existing
         or hereafter  enacted.  To the extent  permitted  by law,  Grantor also
         hereby waives any claims  against the Trustee  arising by reason of the
         fact  that the price at which  any  Collateral  may have been sold at a
         private sale was less than the price which might have been  obtained at
         a public sale, even if the Trustee accepts the first offer received and
         does not offer such  Collateral  to more than one offeree.  In case any
         sale of all or any  part of the  Collateral  is made on  credit  or for
         future delivery,  the Collateral so sold may be retained by the Trustee
         until the sale price is paid by the  purchaser or  purchasers  thereof,
         and the  Trustee  shall  not  incur  any  liability  in case  any  such
         purchaser  or  purchasers  shall  fail  to  take  up and  pay  for  the
         Collateral purchased.  In case of any such failure, such Collateral may
         be sold again  upon like  notice.  The  parties


                                       22





         hereto agree that the notice  provisions,  method,  manner and terms of
         any sale,  transfer or disposition of any Collateral in compliance with
         the terms set forth herein or any other provision of this Agreement are
         commercially reasonable.

                  10.7. Certain Sales of Collateral.

                           (a) Grantor  recognizes  that,  by reason of  certain
         prohibitions  contained  in law,  rules,  regulations  or orders of any
         Governmental Authority,  the Trustee may be compelled,  with respect to
         any sale of all or any part of the Collateral,  to limit  purchasers to
         those who meet the requirements of such Governmental Authority. Grantor
         acknowledges  that any such  sales may be at prices  and on terms  less
         favorable  to the Trustee than those  obtainable  through a public sale
         without such restrictions,  and,  notwithstanding  such  circumstances,
         agrees that any such  restricted sale shall be deemed to have been made
         in a commercially reasonable manner.

                           (b) With   respect   to  the   sale   of   securities
         constituting  Collateral,  to the extent the Trustee deems it advisable
         to do so, in its sole  discretion  or as may be required by  applicable
         law, the Trustee may restrict the prospective  bidders or purchasers to
         Persons  who,  in  the  Trustee's  sole  judgment,   are   sufficiently
         sophisticated and who will represent and agree that they are purchasing
         the securities  constituting  Collateral  then being sold for their own
         account and not with a view to the distribution or resale thereof,  and
         upon consummation of any such sale, the Trustee shall have the right to
         assign, transfer and deliver to the purchaser or purchasers thereof the
         securities constituting Collateral so sold.

                  10.8. Certain Remedies in Respect of Intellectual Property. If
         an Event of Default  shall have  occurred and shall be  continuing,  in
         addition  to the other  rights  and  remedies  provided  for  herein or
         otherwise  available  to it, the  Trustee  may  license  or  sublicense
         (whether general,  special or otherwise, and whether on an exclusive or
         non-exclusive  basis) all or any portion of the  Intellectual  Property
         throughout the world for such term or terms,  on such conditions and in
         such  manner  as the  Trustee  shall  determine.  Upon  request  by the
         Trustee, Grantor shall execute and deliver to the Trustee any powers of
         attorney, in form and substance reasonably  satisfactory to the Trustee
         for the implementation of any assignment, license, sublicense, grant of
         option, sale or other disposition of any Intellectual  Property. In the
         event  of any  sale,  assignment,  or other  disposition  of any of the
         Intellectual  Property,  the goodwill and general intangibles connected
         with  and  symbolized  by the  Intellectual  Property  subject  to such
         disposition shall be included,  and Grantor shall supply to the Trustee
         or its  designee,  for  inclusion  in such  sale,  assignment  or other
         disposition,  all Intellectual  Property  relating to such Intellectual
         Property.  Notwithstanding the foregoing or any other provision hereof,
         the provisions of this Security Agreement, including this Section 10.8,
         are subject to the  Trademark  License  Agreement,  dated as of June 3,
         1999,  between Riviera Operating  Corporation and Grantor,  and the use
         and enjoyment by the Trustee of the license rights  thereunder shall be
         subject to the limitations contained therein.


                                       23





                  10.9.  Specific  Performance.  In addition to any of the other
         rights and  remedies  hereunder,  the  Trustee  shall have the right to
         institute a proceeding seeking specific  performance in connection with
         any of the agreements or obligations hereunder.

                  10.10. Receivership.  Upon and  during  the  continuance of an
         Event of Default,  the Trustee may, to the fullest extent  permitted by
         law,  have a  court  having  jurisdiction  appoint  a  receiver,  which
         receiver  shall take charge and  possession  of and protect,  preserve,
         replace and repair the  Collateral or any part thereof,  and manage and
         operate the same, and receive and collect all rents, income,  receipts,
         royalties, revenues, issues and profits therefrom. Except to the extent
         prohibited  by law,  Grantor  shall  irrevocably  consent  and shall be
         deemed to have hereby irrevocably consented to the appointment thereof,
         and upon such appointment, Grantor shall immediately deliver possession
         of such Collateral to the receiver.  Except to the extent prohibited by
         law,  Grantor  also  irrevocably  consents  to the  entry  of an  order
         authorizing  such  receiver to invest  interest  upon any funds held or
         received by the  receiver in  connection  with such  receivership.  The
         Trustee shall be entitled to such  appointment as a matter of right, if
         it shall so  elect,  without  the  giving  of  notice  to any party and
         without regard to the adequacy of the security of the Collateral.

SECTION 11.    Application  of Proceeds.  All cash  proceeds  received by the
Trustee upon any sale of,  collection of, or other  realization upon, all or any
part of the Collateral shall be applied as follows:

                  First: To the payment of all reasonable out-of-pocket expenses
         incurred by the Trustee in connection  with the sale of,  collection of
         or other realization upon Collateral,  including reasonable  attorneys'
         fees and disbursements and court costs, if applicable;

                  Second:  To  the  payment  of  the  Obligations in such manner
         consistent  with applicable law and the Indenture as the Trustee in its
         discretion shall decide; and

                  Third: To the extent of the balance (if any) of such proceeds,
         to payment to Grantor or other Person legally entitled thereto.

         Non-cash  proceeds  of any  disposition  by the  Trustee of  Collateral
available to satisfy the Obligations shall be applied to the Obligations in such
order and in such manner consistent with applicable law and the Indenture as the
Trustee in its discretion shall decide.

SECTION  12.   Expenses.  Grantor  will  immediately  upon  demand pay to the
Trustee the amount of any and all reasonable expenses,  including the reasonable
fees and  expenses of the  Trustee's  counsel  and the fees and  expenses of any
experts  and  agents  which the  Trustee  may incur in  connection  with (a) the
collection of the Obligations,  (b) the enforcement and  administration  of this
Agreement or any other Collateral Document,  (c) the custody or preservation of,
or  the  sale  of,  collection  from,  or  other  realization  upon,  any of the
Collateral,  (d) the exercise or enforcement of any of the rights of the Trustee
or any Secured Party hereunder, (e) the failure by Grantor to perform or observe
any of the provisions  hereof,  (f) the  preparation  and filing or recording of
financing  statements  and other  documents  (including  all taxes in


                                       24





connection  therewith) in  public offices necessary or desirable  to  create and
maintain first priority  perfected security interests in the Collateral in favor
of the Trustee,  (g) the payment or discharge of any taxes,  insurance  premiums
required or permitted under any Collateral Document or encumbrances with respect
to the  Collateral,  (h)  defending or  prosecuting  any actions or  proceedings
arising out of or related to the  transactions  to which this Agreement  relates
(other than  actions by Grantor for breach of the  Indenture  or any  Collateral
Documents  determined  by  a  court  of  competent  jurisdiction  pursuant  to a
non-appealable  order), or (i) otherwise  protecting,  maintaining or preserving
the Collateral and the perfection and priority of the security interests granted
or purported to be granted hereunder, or the enforcing,  foreclosing,  retaking,
holding, storing, processing, selling or otherwise realizing upon the Collateral
and  the  Trustee's   security  interest   therein,   whether  through  judicial
proceedings or otherwise.  All amounts  payable by Grantor under this Section 12
shall be due upon  demand and shall be  secured  hereby and shall be part of the
Obligations.  Grantor's  obligations  under this  Section 12 shall  survive  the
termination of this Agreement and the discharge of Grantor's  other  obligations
hereunder.

SECTION 13.    Amendments in Writing; No Waiver, Cumulative Remedies; Reinstate-
ment; Additional Grantor.

                  13.1. Amendments Subject to the provisions of Article 9 of the
         Indenture,  none of the terms or  provisions  of this  Agreement may be
         waived,  amended,  supplemented  or  otherwise  modified,  except  by a
         written instrument executed by Grantor (except as otherwise provided in
         Section  13.4) and the  Trustee;  provided  that any  provision of this
         Agreement imposing  obligations on Grantor may be waived by the Trustee
         in a written instrument executed solely by the Trustee.

                  13.2. No Waiver; Remedies  Cumulative. To the  maximum  extent
         permitted  by  law,  (a) no  failure  on the  part  of the  Trustee  to
         exercise,  no course of dealing  with  respect  to, and no delay on the
         part of the  Trustee in  exercising,  any right,  power,  privilege  or
         remedy  hereunder  shall  operate as a waiver  thereof or constitute an
         acquiescence  to any  Default  or Event of  Default;  (b) no  single or
         partial  exercise  of  any  such  right,  power,  privilege  or  remedy
         hereunder nor any taking,  exchange,  release or  non-perfection of any
         other  collateral,  nor any release or  amendment  of or consent to any
         departure  from  any  guarantees  for  all or  any of the  Obligations,
         preclude  any other or future  exercise  thereof or the exercise of any
         other  right,  power or remedy,  and (c) the  Trustee's  acceptance  of
         partial  payment  or  performance  will not  extend or affect any grace
         period  or  constitute  a waiver of a Default  or Event of  Default.  A
         waiver by the Trustee or any Holder of any right or remedy hereunder on
         any one occasion shall not be construed as a bar to any right or remedy
         which the Trustee or such  Holder  would  otherwise  have on any future
         occasion.  To the maximum extent  permitted by law, the remedies herein
         provided are cumulative and are not exclusive of any remedies  provided
         by law.

                  13.3.  Reinstatement.  In  the event the  Trustee  shall  have
         instituted any  proceeding to enforce any right,  power or remedy under
         this  Agreement by  foreclosure,  sale,  entry or  otherwise,  and such
         proceeding shall have been  discontinued or abandoned for any reason or
         shall have been determined adversely to the Trustee,  then and in every
         such case,  Grantor,  the Trustee and each Holder  shall be restored to
         their respective


                                       25





         former  positions and rights  hereunder with respect to the Collateral,
         and all  rights,  remedies  and powers of the  Trustee  and the Secured
         Parties shall continue as if no such proceeding had been instituted.

                  13.4.  Additional Grantors. If Grantor shall acquire or create
         a Restricted  Subsidiary  after the date of this Agreement,  then  such
         newly acquired or created Restricted  Subsidiary (each such  Restricted
         Subsidiary,  an "Additional Grantor") shall (i) become a party  to this
         Agreement by executing  and  delivering to the Trustee an Amendment  to
         Security Agreement  (Additional  Grantor) in substantially the form  of
         Annex I hereto (each, an "Amendment to Security  Agreement  (Additional
         Grantor)"),  and (ii)  shall  enter  into such  documents  as  shall be
         necessary,  in the  Trustee's  opinion,  to create  a perfected,  first
         priority  security  interest  in  the  capital  stock  (to  the  extent
         required to be pledged under the  Indenture)  and  all property of such
         Restricted  Subsidiary (including without limitation  any real property
         and all  personal  property  of such  Restricted  Subsidiary)  and  the
         proceeds and products thereof.  Upon the execution and delivery to  the
         Trustee  by   any  Additional  Grantor  of  an  Amendment  to  Security
         Agreement (Additional Grantor),  which Amendment to Security  Agreement
         (Additional  Grantor)  need  not  be  executed  by   Grantor,  and  the
         acceptance  thereof by the Trustee,  such Additional  Grantor shall  be
         and become a Grantor  hereunder,  and each reference in this  Agreement
         to the  "Grantor"  shall  include  such  Additional  Grantor  and  each
         reference in the Indenture,  the Securities and  any other  Transaction
         Document to the "Grantor" shall include such Person.

SECTION 14.    Appointment as the Trustee.  The actions of the Trustee hereunder
are subject to the provisions of the Indenture. The Trustee shall have the right
hereunder  to make  demands,  to give  notices,  to  exercise  or  refrain  from
exercising  any rights,  and to take or refrain  from taking  action  (including
without  limitation the release or substitution of Collateral),  in each case in
accordance  with this Agreement and the Indenture.  The Trustee may resign and a
successor Trustee may be appointed in the manner provided in the Indenture. Upon
the acceptance of any  appointment as the Trustee by a successor  Trustee,  such
successor  Trustee  shall  thereupon  succeed to and become  vested with all the
rights,  powers,  privileges  and  duties of the  retiring  Trustee  under  this
Agreement,  and the retiring  Trustee  shall  thereupon be  discharged  from its
duties  and  obligations  under this  Agreement.  After any  retiring  Trustee's
resignation,  the provisions of this Agreement  shall inure to its benefit as to
any actions taken or omitted to be taken by it under this Agreement while it was
the Trustee.

SECTION 15.    The Trustee Appointed Attorney-in-Fact; the Trustee May Perform.

                  15.1. The  Trustee  Appointed  as  Attorney-in-Fact.   Grantor
         hereby  irrevocably  constitutes  and  appoints  the  Trustee  and  any
         officer or agent thereof, with full power of substitution, as its  true
         and lawful  attorney-in-fact with full irrevocable power and  authority
         in the place and stead of Grantor  and in the name of  Grantor,  or  in
         its own  name,  for the  purpose  of  carrying  out the  terms of  this
         Agreement  to take any and all  appropriate  action and to execute  any
         and all documents and instruments  which may be necessary or  desirable
         to accomplish  the purposes of this  Agreement.  Without  limiting  the
         generality of the foregoing,  Grantor hereby gives the Trustee and  any
         officer or agent of the Trustee the


                                       26





         power and right,  on behalf of Grantor,  without notice to or assent by
         Grantor, to do any or all of the following:

                           (a) in  the  name  of  Grantor  or  its own  name, or
         otherwise,  take  possession  of and  endorse  and  collect any checks,
         drafts,  notes,  acceptances  or other  instruments  for the payment of
         monies due under any Contract or with  respect to any other  Collateral
         and file any claim or take any other action or  proceeding in any court
         of law or equity or otherwise deemed appropriate by the Trustee for the
         purpose of collecting any and all such monies due under any Contract or
         with respect to any other Collateral whenever payable;

                           (b) in   the  case   of  any  Copyright,   Patent  or
         Trademark,  execute and deliver  any and all  agreements,  instruments,
         documents  and  papers as the  Trustee  may  determine  appropriate  to
         evidence the Trustee's  security interest in such Copyright,  Patent or
         Trademark and the goodwill and general  intangibles of Grantor relating
         thereto or represented thereby;

                           (c) pay  or  discharge  taxes  and   Liens  levied or
         placed on or threatened  against the Collateral,  effect any repairs or
         any insurance  called for by the terms of this Agreement and pay all or
         any part of the premiums therefor and the costs thereof;

                           (d) execute,  in  connection  with  any sale provided
         for in  Sections  10.3,  10.4 or 10.5 or any other  sale of  Collateral
         pursuant to this  Agreement,  any  endorsements,  assignments  or other
         instruments  of conveyance or transfer with respect to the  Collateral;
         and

                           (e)  (i) direct  any  party  liable  for any  payment
         under any of the  Collateral  to make payment of any and all monies due
         or to become due  thereunder  directly to the Trustee or as the Trustee
         shall direct;  (ii) ask or demand for, collect,  receive payment of and
         receipt  for,  any and all monies,  claims and other  amounts due or to
         become due at any time in respect of or arising out of any  Collateral;
         (iii) sign and endorse any invoices, freight or express bills, bills of
         lading,   storage  or  warehouse  receipts,   drafts  against  debtors,
         assignments,  verifications,  notices and other documents in connection
         with any of the  Collateral;  (iv)  commence and  prosecute  any suits,
         actions or  proceedings  at law or in equity in any court of  competent
         jurisdiction  to collect the  Collateral  or any thereof and to enforce
         any other  right in  respect  of any  Collateral;  (v) defend any suit,
         action or  proceeding  brought  against  Grantor  with  respect  to any
         Collateral;  (vi) settle, compromise or adjust any such suit, action or
         proceeding  and, in connection  therewith,  to give such  discharges or
         releases  as the  Trustee may deem  appropriate;  and (vii)  generally,
         sell,  transfer,  pledge  and make any  agreement  with  respect  to or
         otherwise  deal with any of the  Collateral as fully and  completely as
         though the Trustee were the absolute  owner  thereof for all  purposes,
         and do, at the Trustee's option and Grantor's expense,  at any time, or
         from  time to  time,  all acts  and  things  which  the  Trustee  deems
         necessary to protect,  preserve or realize upon the  Collateral and the
         Trustee's and the Holders' security interests therein and to effect the
         intent of this Agreement, all as fully and effectively as Grantor might
         do.


                                       27





                  The  foregoing  grant  of  authority  is a power  of  attorney
         coupled  with an interest  and such  appointment  shall be  irrevocable
         until this Agreement is terminated and the security  interests  created
         hereby are released.  Grantor  hereby  ratifies all that such attorneys
         shall lawfully do or cause to be done by virtue and in accordance  with
         the  terms  hereof.  Anything  in this  Section  15.1  to the  contrary
         notwithstanding,  the  Trustee  agrees  that it will not  exercise  any
         rights  under the power of attorney  provided  for in this Section 15.1
         unless an Event of Default shall have occurred and be continuing.

                  15.2. The Trustee May Perform. If Grantor shall fail to do any
         act or thing  that it has  covenanted  to do  hereunder  or  under  the
         Indenture within any applicable grace period with respect thereto or if
         any  representation or warranty on the part of Grantor contained herein
         or under the  Indenture  shall be breached,  the Trustee or any Secured
         Party may (but shall not be obligated to), after providing Grantor with
         at least ten days' notice, do the same or cause it to be done or remedy
         any such  breach,  and may expend funds for such  purpose.  Any and all
         amounts so expended by the Trustee or such Secured  Party shall be paid
         by Grantor promptly upon demand therefor,  with interest at the Default
         Rate during the period from and  including the date on which such funds
         were so expended to the date of repayment.  Grantor's obligations under
         this Section shall survive the  termination  of this  Agreement and the
         discharge of Grantor's other obligations under this Agreement.

                  15.3. Duty  of the Trustee.   The  Trustee's  sole  duty  with
         respect to the custody,  safekeeping  and physical  preservation of the
         Collateral in its possession,  under  Section 9-207 of the UCC, Section
         9 hereof or otherwise,  shall be to deal  with it in the same manner as
         the Trustee deals with similar  property for  its own account.  Neither
         the  Trustee,  any  Holder  nor  any  of  their   respective  officers,
         directors,  employees or agents shall be liable  for failure to demand,
         collect  or  realize  upon any of the  Collateral  or for  any delay in
         doing so or shall be under any obligation to sell or otherwise  dispose
         of any  Collateral  upon the request of Grantor or any other person  or
         to take any other action  whatsoever  with regard to the Collateral  or
         any part thereof.  The powers conferred on the Trustee and the  Holders
         hereunder  are  solely  to  protect  the  Trustee's  and  the  Holders'
         interests  in the  Collateral  and shall not  impose any duty  upon the
         Trustee or any Holder to exercise any such powers. The Trustee and  the
         Holders  shall be  accountable  only for  amounts  that  they  actually
         receive as a result of the exercise of such  powers,  and  neither they
         nor any of their  officers,  directors,  employees  or  agents shall be
         responsible to Grantor for any act or failure to act  hereunder, except
         for their own gross negligence or willful  misconduct.  Except  for the
         safe custody of any  Collateral in its  possession  and the  accounting
         for monies actually  received by it hereunder,  the Trustee shall  have
         no duty as to any Collateral, as to ascertaining or taking action  with
         respect to calls, conversions, exchanges, maturities, tenders or  other
         matters relative to any Collateral,  whether or not the Trustee has  or
         is deemed to have  knowledge of such  matters,  or as to the taking  of
         any necessary  steps to preserve  rights  against prior parties or  any
         other rights pertaining


                                       28





         thereto. Nothing contained in this Agreement shall be
         construed as requiring or  obligating  the Trustee or the Holders,  and
         neither the Trustee nor the Holders shall be required or obligated,  to
         (a) present or file any claim or notice or take any action with respect
         to any  Collateral or in connection  therewith or (b) notify Grantor of
         any decline in the value of any Collateral.

                  15.4.  Execution of Financing Statements.  Pursuant to Section
         9-402(2)(e) of the UCC, Grantor  authorizes the Trustee (subject to the
         last  sentence  of  Section  5.2)  to  file  financing  statements  and
         continuation  statements  with  respect to the  Collateral  without the
         signature  of  Grantor in such form and in such  filing  offices as the
         Trustee  reasonably  determines  appropriate  to perfect,  and maintain
         perfected,  the security interests of the Trustee under this Agreement.
         A carbon, photographic or other reproduction of this Agreement shall be
         sufficient as a financing statement for filing in any jurisdiction.  At
         the time the Riviera  Black Hawk is first  Operating (as such terms are
         defined  in the  Indenture),  so long as  Grantor's  place of  business
         (within the meaning of the UCC) at such time is located in the State of
         Colorado,  the  Trustee  shall,  at  Grantor's  expense,  execute  such
         termination   statements  prepared  by  Grantor,  and  as  Grantor  may
         reasonably  request, to terminate any financing  statements  previously
         filed  in the  State  of  Nevada  in  connection  with  the  Collateral
         Documents on the basis that Grantor's  place of business at the time of
         such filings was located in the State of Nevada (and the parties hereto
         acknowledge  that the financing  statement filed in the State of Nevada
         in  connection  with  the  execution  and  delivery  of the  Collateral
         Documents was so filed on the theory that  Grantor's  place of business
         at such time was in the State of Nevada); provided that nothing in this
         sentence shall prohibit or impair the Trustee's right to file or direct
         the filing of any financing statements in future in any jurisdiction in
         accordance with the provisions of this Agreement.

                  15.5. Authority of the Trustee.  Grantor acknowledges that the
         rights and  responsibilities  of  Grantor  under  this  Agreement  with
         respect  to  any  action  taken  by the  Trustee  or  the  exercise  or
         non-exercise  by the  Trustee of any  option,  voting  right,  request,
         judgment or other right or remedy  provided  for herein or resulting or
         arising  out of this  Agreement  shall,  as between the Trustee and the
         Holders, be governed by the Indenture and by such other agreements with
         respect  thereto  as may exist from time to time among  them,  but,  as
         between the  Trustee and  Grantor,  the Trustee  shall be  conclusively
         presumed  to be  acting as agent  for the  Holders  with full and valid
         authority so to act or refrain from acting,  and Grantor shall be under
         no obligation,  or  entitlement,  to make any inquiry  respecting  such
         authority.  The Trustee may exercise  its rights  under this  Agreement
         through an agent or other designee.

SECTION 16.    Notices.  All notices,  requests, demands and other communication
shall be given in the  manner set forth in Section  11.02 of the  Indenture  and
shall be given or delivered at the following  respective addresses and facsimile
and  telephone  numbers and to the  attention of the  following  individuals  or
departments:  (i)  if to  Grantor,  at its  address  specified  pursuant  to the
Indenture;  (ii) if to the  Trustee,  at its address  specified  pursuant to the
Indenture;  or (iii) as to any such party,  at such other address,  facsimile or
telephone number, or to the attention of such other


                                       29





individual or department,  as the party to which such  information  pertains may
hereafter  specify  for  the  purpose  in a  notice  to the  other  specifically
captioned "Notice of Change of Address."

SECTION 17.    Continuing Security Interest;  Assignment.  This Agreement shall
create a continuing security interest in the Collateral and shall (a) be binding
upon  Grantor,  its  successors  and assigns,  and (b) inure,  together with the
rights and  remedies  of the  Trustee  hereunder,  to the benefit of the Trustee
(and, to the extent provided herein,  any other trustee under the Deed of Trust)
and  the  other  Secured  Parties  and  each  of  their  respective  successors,
transferees and assigns;  and no other Persons (including without limitation any
other  creditors  of  Grantor)  shall have any  interest  herein or any right or
benefit with respect  hereto.  Without  limiting the generality of the foregoing
clause (b), any Secured  Party may assign or otherwise  transfer any security or
guarantee  held by it secured by this  Agreement to any other  Person,  and such
other  Person  shall  thereupon  become  vested with all the benefits in respect
thereof granted to such Secured Party, herein or otherwise, subject, however, to
the provisions of the Indenture.

SECTION 18.    Release of Collateral. Reference is hereby made to Article 10 of
the Indenture for provisions  which discuss the release of the  Collateral  from
the Liens created by this Agreement.

SECTION 19.    Termination. When all Obligations have been indefeasibly paid in
full, this Agreement shall terminate  (except as to those provisions which it is
provided herein shall survive such  termination) and the Trustee shall forthwith
cause to be assigned, transferred and delivered, against receipt but without any
recourse,  warranty or representation  whatsoever,  any remaining Collateral and
money  received in respect  thereof,  to or to the order of  Grantor,  and to be
released  and  canceled,  all  licenses  and rights  referred  to in Section 7.4
hereof;  provided,  however,  that any  licenses or  sublicenses  granted by the
Trustee  pursuant to Section 10.8 shall  continue to be in full force and effect
in  accordance  with their terms.  The Trustee shall also execute and deliver to
Grantor upon such  termination  such UCC  termination  statements and such other
documentation  as shall  be  reasonably  requested  by  Grantor  to  effect  the
termination and release of the security interests in the Collateral.

SECTION 20.    GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY, AND SHALL BE
CONSTRUED  AND ENFORCED IN  ACCORDANCE  WITH,  THE LAWS OF THE STATE OF NEW YORK
(INCLUDING WITHOUT LIMITATION SECTION 5-1401 OF THE NEW YORK GENERAL OBLIGATIONS
LAW) WITHOUT REGARD TO THE PRINCIPLES OF CONFLICT OF LAWS THEREOF, EXCEPT TO THE
EXTENT THAT THE PERFECTION AND ENFORCEMENT OF THE SECURITY  INTERESTS  HEREUNDER
IN RESPECT OF ANY  PARTICULAR  COLLATERAL  ARE  GOVERNED  BY THE LAWS OF ANOTHER
JURISDICTION.

SECTION 21.    Severability  of  Provisions.  Any  provision   of this Agreement
which is prohibited  or  unenforceable  in any  jurisdiction  shall,  as to such
jurisdiction,   be   ineffective   to  the   extent  of  such   prohibition   or
unenforceability   without  invalidating  the  remaining  provisions  hereof  or
affecting  the  validity  or  enforceability  of  such  provision  in any  other
jurisdiction.

SECTION 22.    Interaction with Indenture.

                           (a) Incorporation   by    Reference.   All     terms,
         covenants, conditions, provisions and requirements of the Indenture are
         incorporated by reference in this Agreement.

                           (b) Conflicts.  Notwithstanding  any  other provision
         of this Agreement,  the terms and provisions of this Agreement shall be
         subject and  subordinate to the terms of the  Indenture.  To the extent
         that the Indenture  provides  Grantor with a particular  cure or notice
         period,  or establishes  any limitations or conditions on the Trustee's
         actions  with regard to a  particular  set of facts,  Grantor  shall be
         entitled to the same cure periods and notice  periods,  and the Trustee
         shall be subject to the same  limitations  and  conditions,  under this
         Agreement, as under the Indenture, in place of the cure periods, notice
         periods,  limitations and conditions provided for under this Agreement;
         provided, however, that such cure periods, notice periods,  limitations
         and  conditions  shall not be  cumulative  as between the Indenture and
         this Agreement.  In the event of any conflict or inconsistency  between
         the provisions of this Agreement and those of the Indenture,  including
         without  limitation any conflicts or inconsistencies in any definitions
         herein or therein,  the  applicable  provisions or  definitions  of the
         Indenture shall govern.

SECTION  23.   Other  Security.  To  the  extent that the Obligations are now or
hereafter  secured by property  other than the  Collateral or by the  guarantee,
endorsement  or property of any other  Person,  then the Trustee  shall have the
right in its sole discretion to pursue, relinquish,  subordinate, modify or take
any other action with respect thereto, without in any way modifying or affecting
any of the Trustee's or any Holder's rights and remedies hereunder.

SECTION 24.    Execution in  Counterparts.  This  Agreement and any  amendments,
waivers,  consents  or  supplements  hereto  may be  executed  in any  number of
counterparts and by different parties hereto in separate  counterparts,  each of
which when so executed and delivered shall be deemed to be an original,  but all
such counterparts together shall constitute one and the same agreement.

SECTION  25.   Headings.  The Section and  subsection  headings  used in this
Agreement  are for  convenience  of  reference  only and  shall not  affect  the
construction or interpretation of this Agreement.

SECTION 26.    Additional Grantor Obligations Absolute.  All obligations of any
Additional  Grantor hereunder shall be absolute and  unconditional  irrespective
of:

                           (a) any   Bankruptcy,   insolvency,   reorganization,
         arrangement, readjustment,  composition, liquidation or the like of the
         Company or any Additional Grantor;

                           (b) any  lack  of validity or  enforceability  of the
         Indenture,  the Completion  Capital  Commitment,  the Securities or any
         other Transaction Document;

                           (c) any   change  in the  time,  manner  or place of
         payment of, or in any other term of, all or any of the Obligations,  or
         any other  amendment or waiver of or any


                                       31





         consent to any departure  from the Indenture,  the  Completion  Capital
         Commitment, the Securities or any other Transaction Document (except to
         the extent specified in such change, amendment or waiver);

                           (d) any taking, exchange,  release or non-perfection
         of any other  collateral,  or any release or  amendment or waiver of or
         consent to any  departure  from any  guarantees,  for all or any of the
         Obligations;

                           (e) any  exercise or  non-exercise,  or any waiver of
         any  right,  remedy,  power or  privilege  under or in  respect of this
         Agreement,  the  Indenture,  the  Completion  Capital  Commitment,  the
         Securities or any other  Transaction  Document,  except as specifically
         set  forth  in a  waiver  granted  pursuant  to the  provisions  of the
         Indenture;

                           (f) any  manner  of  application  of  collateral,  or
         proceeds  thereof,  to all or any of the Obligations,  or any manner of
         sale  or  other  disposition  of any  collateral  for all or any of the
         Obligations  or any other  obligations of the Company or any Additional
         Grantor under the Indenture,  the  Securities or any other  Transaction
         Document or any other assets of the Company,  any Additional Grantor or
         any of their respective Subsidiaries;

                           (g) any  change,  restructuring or termination of the
         organizational  structure or existence of the Company,  any  Additional
         Grantor or any of their respective Subsidiaries;

                           (j) any  failure of the Trustee or any Secured  Party
         to  disclose  to Grantor  any  information  relating  to the  business,
         condition (financial or otherwise), operations, properties or prospects
         of the  Company or any other  Additional  Grantor  now or in the future
         known to the  Trustee  or any  other  Secured  Party  (such  Additional
         Grantor  hereby  waiving  any duty on the part of the  Trustee  and any
         other Secured Party to disclose such information); or

                           (i) any   other   circumstance   (including  without
         limitation any statute of  limitations) or any existence of or reliance
         on any  representation  by the Trustee or any other  Secured Party that
         might otherwise  constitute a defense  available to, or a discharge of,
         the Company or any Additional Grantor or any guarantor or surety.

         Notwithstanding  the  foregoing,  nothing  in this  Section 26 shall be
deemed to impair or modify the rights or obligations  otherwise  expressly given
to or agreed to by the Additional Grantor in any of the Loan Documents.

SECTION  27.   Waiver of Marshaling.  Grantor,  for itself and for all Persons
hereafter  claiming  through or under it or who may at any time hereafter become
holders  of liens  junior to the liens  granted  under  this  Agreement,  hereby
expressly waives and releases all rights to direct the order in which any of the
Collateral  shall be sold in the event of any sale or sales pursuant  hereto and
to have  any of the  Collateral  and/or  any  other  property  now or  hereafter
constituting  security for any of the obligations  secured  hereunder  marshaled
upon the exercise of any remedies


                                       32





under  this  Agreement  or  any  other  agreement   granting  security  for  the
obligations secured hereunder.

SECTION 28.   Independence  of Covenants.  All covenants  hereunder shall be
given  independent  effect so that if a  particular  action or  condition is not
permitted  by any of such  covenants,  the fact that it would be permitted by an
exception to, or be otherwise  within the limitations of, another covenant shall
not  avoid the  occurrence  of a default  if such  action is taken or  condition
exists.

SECTION 29.    Savings  Clause.  It is the intention of the parties to conform
strictly to the usury laws, whether state or federal, that are applicable to the
transaction of which this Agreement is a part.  All agreements  between  Grantor
and the Trustee,  whether now existing or hereafter  arising and whether oral or
written,  are  hereby  expressly  limited  so that in no  contingency  or  event
whatsoever  shall the amount  paid or agreed to be paid by Grantor  for the use,
forbearance  or  detention  of the  money to be  loaned  or  advanced  under the
Indenture,  the Securities,  the Completion  Capital  Commitment,  the Keep-Well
Agreement,  this Agreement or any other Transaction Document, or for the payment
or performance of any covenant or obligation contained herein or therein, exceed
the maximum amount  permissible under applicable federal or state usury laws. If
under any  circumstances  whatsoever  fulfillment of any such provision,  at the
time  performance  of such provision  shall be due, shall involve  exceeding the
limit of validity  prescribed by law, then the obligation to be fulfilled  shall
be reduced to the limit of such  validity.  If under any  circumstances  Grantor
shall have paid an amount deemed  interest by applicable law, which would exceed
the highest  lawful  rate,  such amount that would be excessive  interest  under
applicable  usury laws shall be applied to the reduction of the principal amount
owing in respect of the  Obligations  and not to the payment of interest,  or if
such  excessive  interest  exceeds the unpaid balance of principal and any other
amounts due hereunder, the excess shall be refunded to Grantor. All amounts paid
or agreed to be paid for the use,  forbearance  or  detention  of the  principal
under any  extension  of credit or  advancement  of funds by the  Trustee or any
Holder  shall,  to the extent  permitted  by law and to the extent  necessary to
preclude  exceeding  the limit of  validity  prescribed  by law,  be  amortized,
prorated,  allocated and spread from the date of this Agreement until payment in
full of the  Obligations  so that the actual rate of interest on account of such
principal amounts is uniform throughout the term hereof.

SECTION 30.    Certain  Waivers  by Grantor.  Grantor waives (a) any claim that,
as to any part of the Collateral,  a public sale, should the Trustee elect so to
proceed, is, in and of itself, not a commercially  reasonable method of sale for
such  Collateral,  (b) except as otherwise  provided in this  Agreement,  to the
fullest extent not prohibited by applicable laws,  notice or judicial hearing in
connection with the Trustee's  disposition of any of the  Collateral,  including
any and all prior  notice and hearing for any  pre-judgment  remedy or remedies,
and all  other  requirements  as to the  time,  place and terms of sale or other
requirements  with respect to the enforcement of the Trustee's rights hereunder,
(c) all rights of  redemption,  appraisal or  valuation,  and (d) all rights and
defenses  arising out of an election  of  remedies  by any Secured  Party,  even
though that election of remedies, such as a nonjudicial foreclosure with respect
to security for a  guaranteed  obligation,  has  destroyed  Grantor's  rights of
subrogation and reimbursement against the principal.


                                       33





SECTION 31.    WAIVER OF JURY TRIAL. THE TRUSTEE AND GRANTOR HEREBY WAIVE TRIAL
BY JURY IN ANY  JUDICIAL  PROCEEDINGS  INVOLVING,  DIRECTLY OR  INDIRECTLY,  ANY
MATTER  (WHETHER  IN TORT,  CONTRACT  OR  OTHERWISE)  IN ANY WAY ARISING OUT OF,
RELATED TO, OR CONNECTED  WITH THIS  AGREEMENT OR THE  RELATIONSHIP  ESTABLISHED
HEREUNDER.

SECTION 32.   Gaming  Laws.  Notwithstanding  any   provision   herein   to  the
contrary,  the grant of security  interest and the terms and  provisions of this
Agreement, including, but not limited to, all rights and remedies of the Trustee
and powers of  attorney  and  appointment,  are  expressly  subject to all laws,
statutes,  regulations and orders affecting limited gaming or the sale of liquor
(collectively,  the "Gaming Laws"), in the State of Colorado, which may include,
but not be  limited  to,  the  necessity  for the  Trustee  to obtain  the prior
approval of the regulatory  agencies enforcing the Gaming Laws before taking any
action  hereunder  and  to  be  licensed  by  such  regulatory  agencies  before
exercising certain rights and remedies hereunder.

SECTION 33.    Entire Agreement.  This written  agreement  represents the final
agreement  between the parties with respect to the subject matter hereof and may
not be  contradicted by evidence of prior,  contemporaneous,  or subsequent oral
agreements of the parties with respect to the subject matter  hereof.  There are
no  unwritten  oral  agreements  among the parties  with  respect to the subject
matter hereof.


                                       34





         IN WITNESS  WHEREOF,  Grantor and the Trustee have caused this Security
Agreement to be duly executed and delivered as of the date first above written.

                         AMENDMENT TO SECURITY AGREEMENT
                              (ADDITIONAL GRANTOR)


         This  Amendment  to  Security  Agreement   (Additional  Grantor)  (this
"Amendment"),  dated as of ___________,  ____, relates to the Security Agreement
dated as of June 3, 1999, as amended,  modified and  supplemented to date (as so
amended,  supplemented or modified,  the "Agreement")  executed by Riviera Black
Hawk, Inc., a Colorado corporation  ("Grantor") in favor of IBJ Whitehall Bank &
Trust Company,  as trustee (in such  capacity,  together with its successors and
assigns,  the "Trustee"),  for the benefit of the Secured Parties (as defined in
the Agreement).  Capitalized  terms used but not otherwise  defined herein shall
have the meanings given in the Agreement.

         In compliance  with Section 4.20 of the  Indenture  dated as of June 3,
1999 (as amended,  supplemented  or otherwise  modified  from time to time,  the
"Indenture")  between Grantor and the Trustee,  [NAME OF RESTRICTED  SUBSIDIARY]
("Additional Grantor") and the Trustee hereby agree as follows:

         1.  Amendment.  The Agreement is hereby amended to add as a party,  and
more specifically, as a Grantor thereunder, Additional Grantor.

         2.  Representations  and Warranties.  Additional Grantor represents and
warrants  to  the  Trustee  and  each  other  Secured  Party  that  each  of the
representations  and warranties of Grantor  contained in the Agreement is hereby
made by Additional  Grantor on and as of the date hereof and is true and correct
as to Additional Grantor.

         3.  Grant of  Security  Interest.  Additional  Grantor  hereby  grants,
pledges,  assigns and  transfers to the Trustee,  for the  Trustee's  individual
benefit and the ratable  benefit of the Holders,  as security for the prompt and
complete  payment and  performance  when due (whether at stated  maturity,  upon
redemption  or required  repurchase,  by  acceleration  or otherwise) of all the
Obligations  of  Additional  Grantor,  a  continuing  first  priority  perfected
security  interest  in and  lien on all of the  right,  title  and  interest  of
Additional  Grantor  in,  to and  under  all  types  and  items of  property  of
Additional  Grantor  within the  definition  of  Collateral  (as  defined in the
Agreement),  in each case  wherever  located,  whether  now owned or at any time
hereafter  acquired by  Additional  Grantor,  whether now  existing or hereafter
coming into existence,  or in which Additional Grantor now has or at any time in
the future may acquire any right, title or interest.

         4.  Schedule  Supplements.   Additional  Grantor  has  attached  hereto
supplements  to Schedules A through D to the Agreement,  and Additional  Grantor
hereby  represents  and warrants  that such  supplements  have been  prepared by

         5.  Assumption  of  Rights,  Obligations  and  Liabilities.  Additional
Grantor  assumes all of the rights,  obligations  and  liabilities  of a Grantor
under the Agreement and agrees to be bound thereby as if Additional Grantor were

foregoing,  Additional Grantor waives notice of the creation, advance, increase,
existence,  extension,  or renewal of, or of any indulgence with respect to, the
Obligations; waives presentment, demand, notice of dishonor, and protest; waives
notice of the amount of the Obligations  outstanding at any time,  notice of any
change in  financial  condition  of  Grantor,  notice of any default or Event of
Default,  and all other notices respecting the Obligations  (except for any such
notices  that are  required to be given to  Additional  Grantor  pursuant to the
other  provisions of this  Agreement or the  provisions of the  Securities,  the
Indenture or any other  Transaction  Document);  and agrees that maturity of the
Obligations and any part thereof may be accelerated, extended, or renewed one or
more  times  by the  Holders,  in its or their  discretion,  without  notice  to
Additional Grantor.

         6.  Effectiveness.  This Amendment  shall become  effective on the date
hereof  upon the  execution  hereof by  Additional  Grantor  and the Trustee and
delivery hereof to the Trustee.

         7.  GOVERNING  LAW. THIS  AMENDMENT  SHALL BE GOVERNED BY, AND SHALL BE

(INCLUDING,   WITHOUT  LIMITATION,  SECTION  5-1401  OF  THE  NEW  YORK  GENERAL
OBLIGATIONS  LAW) WITHOUT  REGARD TO THE  PRINCIPLES  OF CONFLICT  LAWS THEREOF,
EXCEPT  TO THE  EXTENT  THAT THE  PERFECTION  AND  ENFORCEMENT  OF THE  SECURITY
INTERESTS HEREUNDER IN RESPECT OF ANY PARTICULAR  COLLATERAL ARE GOVERNED BY THE
LAWS OF ANOTHER JURISDICTION.

         IN WITNESS WHEREOF, Additional Grantor and the Trustee have caused this
