         THIS ASSIGNMENT OF RENTS,  LEASES AND LEASEHOLD  INTERESTS (as the same

capacity as trustee under the  Indenture  referred to below  (together  with its
successors  and  assigns,  "Assignee")  for its  benefit  and the benefit of the
Holders (as defined herein).

                                    RECITALS

         C. The Indenture  requires that the  obligations  of Assignor under the

for the benefit of Assignee  encumbering  the Property (as defined  below),  and

portions  of the  Property.  Such  leases and  subleases,  and any other  lease,
sublease,  leases or subleases or agreement  for the use and occupancy of all or
any portion(s) of the Property hereafter entered into by Assignor, together with
any and all  guarantees,  amendments,  modifications,  extensions  and  renewals
thereof, are hereinafter referred to as the "Tenant Leases".

         NOW,  THEREFORE,  in consideration of the foregoing  premises and other
good and  valuable  consideration,  the receipt and adequacy of which are hereby
acknowledged, Assignor agrees as follows:

         1.  Definitions.  As used  herein,  capitalized  terms  shall  have the

         2.  Assignment  of  Leases  and  Rents.  Assignor  hereby  irrevocably,
absolutely,  presently,  unconditionally,  and not merely as additional security
for the payment and performance of the Obligations,  sells,  assigns,  sets over
and transfers to Assignee the following property,  rights, interests and estates
now or in  future  owned  or  held  by  Assignor  (collectively,  the  "Assigned
Property"):

                                       2


         (a) any and all rights, title and interest of Assignor in, to and under
the Tenant Leases;

         (b) any and all guaranties of the obligations of the tenants, licensees
or other  occupants  of the  Property  (the  "Tenants")  under any of the Tenant
Leases,  or any other credit  enhancements  given to Assignor in connection with
any Tenant's performance under any of the Tenant Leases;

         (c) the right to the use and  possession of the Property and all of the

Issues and Profits") now due or that may become due or to which Assignor may now
or hereafter (whether during any applicable period of redemption,  or otherwise)
become  entitled  or may demand or claim,  arising  out of or  issuing  from the
Tenant  Leases,  or from or out of the Property or any part  thereof,  including
without limitation  liquidated damages following a default under a Tenant Lease,
any termination, cancellation, modification or other fee or premium payable by a
Tenant to Assignor for any reason and the proceeds of rental insurance;

         (d) the right to the use and possession of any or all of the furniture,
furnishings,  fittings, attachments,  appliances,  machinery, equipment, devices
and  appurtenances  of every kind and description  now or hereafter  affixed to,
located in or on the  Property  or  available  for the use of the Tenants or the
operation of the Property  and in or to which  Assignor has any right,  title or
interest; and

         (e) all rights or causes of action that  Assignor mow of hereafter  may
have against any Tenant.

         Assignor  further  assigns,  transfers and sets over to Assignee all of
Assignor's  right,  title and  interest  in and to all  claims and rights to the
payment of money at any time arising in connection  with any rejection or breach
of any of the Tenant  Leases by a Tenant or trustee of the Tenant under  Section
365 of the Bankruptcy Code, 11 U.S.C.  Section 365, including without limitation
all rights to recover  damages  arising  out of such  breach or  rejection,  all
rights to  charges  payable  by the  Tenant or  trustee in respect of the leased

respect of such lessee and all rentals and other charges  outstanding  under the
Tenant Lease as of the date of entry of such order for relief.

         3. Assignor Limited License.  Provided that no Event of Default exists,
Assignor shall have the right under a license granted hereby and Assignee hereby
grants to Assignor a license to collect, but not more than one month in advance,
all of the Rents, Issues and Profits arising from or out of the Tenant Leases or
any renewals or extensions  thereof,  or from or out of the Property or any part
thereof, but only as trustee for the benefit of Assignee. Thereafter,

                                       3


so long as no Event of Default  exists,  Assignor may use the Rents,  Issues and
Profits in any manner not inconsistent  with the Indenture.  The license granted
hereby  shall  be  revoked  automatically  upon  the  occurrence  of an Event of
Default. If Assignor  nevertheless  collects any Rents, Issues and Profits after
the license granted hereby is revoked, Assignor shall hold the same in trust for
Assignee and shall  immediately  pay the same to Assignee (in the form received,
except for any necessary  endorsement),  without the necessity of any request or
demand therefor.

         4.  Limitation.  The acceptance by Assignee of the assignment  provided
herein,  together  with all of the  rights,  powers,  privileges  and  authority
created herein or elsewhere in this  Assignment,  shall not, prior to entry upon
and taking  possession  of the Property by  Assignee,  be deemed or construed to
constitute  Assignee a "mortgagee in possession,"  nor thereafter or at any time
or in any  event  obligate  Assignee  to  appear  in or  defend  any  action  or
proceeding  relating to the Tenant Leases, the Rents,  Issues and Profits or the
Property  or to take any  action  hereunder  or to expend any money or incur any
expenses  or perform or  discharge  any  obligation  or  responsibility  for any
security deposits or other deposits  delivered to Assignor by any Tenant and not
assigned and delivered to Assignee,  nor shall Assignee be liable in any way for
any injury or damage to person or property  sustained  by any person or persons,
firm or corporation in or about the Property.

         5. Performance by Assignor. Assignor covenants and agrees that it shall
perform its obligations  under the Tenant Leases in accordance with their terms.
Assignor  shall not default in the  performance  of any  obligation  of Assignor
under any Tenant Lease if, by reason of such default,  the Tenant or other party
thereunder  has the right to cancel such Tenant Lease or to claim any diminution
or offset against future Rents, Issues or Profits.

         6. Remedies. Upon the occurrence of any Event of Default, Assignee may,
at its option (in each case,  subject to and in accordance  with any  applicable
terms of the Indenture):

         (a) declare all sums secured hereby and by the Transaction Documents to
be immediately due and payable,  and the same shall thereupon become immediately
due and payable without any presentment, demand, protest or notice of any kind;

         (b) terminate Assignor's right and license to collect the Rents, Issues
and  Profits  and  either in person or by agent,  with or without  bringing  any
action or proceeding,  or by a receiver appointed by a court, and without regard
to the adequacy of its security,  enter upon and take possession of the Property
or any part  thereof,  and do any acts which it deems  necessary or desirable to
preserve the value,  marketability  or rentability of the Property,  or any part
thereof,  and do any acts which it deems  necessary or desirable to preserve the
value,  marketability  or  rentability  of the Property,  or any part thereof or
interest therein, make, modify,  enforce,  cancel or accept the surrender of any
Tenant Lease,  take actions which may affect the income therefrom or protect the
security hereof, and with or without taking possession of the Property,  sue for
or otherwise collect the Rents, Issues and Profits, including without limitation
those  past due and

                                       4



unpaid, and apply the same, less costs and expenses of operation and collection,
including without limitation  reasonable  attorney's fees (including  reasonable
charges for in-house counsel),  upon any indebtedness  evidenced by the Notes or
any other  Transaction  Documents,  all in such order as Assignee may determine.
From and after receipt of prior written notice Assignee to pay Rents, Issues and
Profits  directly to Assignee or another  party  designated  by  Assignee,  each
Tenant  shall pay all such  payments  under its  respective  Tenant Lease in the
manner  instructed by Assignee.  The entering upon and taking  possession of the
Property or any portion thereof, the collection of the Rents, Issues and Profits
and the application thereof as aforesaid, or any of such acts, shall not cure or
waive any default or notice of default or invalidate any act done in response to
such default or pursuant to such notice, and  notwithstanding the continuance in
possession of the Property or the  collection,  receipt and  application  of the
Rents,  Issues and Profits,  Assignee  shall be entitled to exercise every right
provided  for in any of the  Indenture,  the  Notes,  or the  other  Transaction
Documents  or by law upon the  occurrence  of any  Event of  Default,  including
without limitation the right to exercise the power of sale provided herein;

         (c) notwithstanding the availability of legal remedies, obtain specific
performance  mandatory or  prohibitory  injunctive  relief,  or other  equitable
relief requiring Assignor to cure or refrain from repeating any default;

         (d) with or without  accelerating the maturity of the Obligations,  sue
from time to time for any payment due under any of the  Indenture,  the Notes or
the other Transaction Documents,  or for money damages resulting from Assignor's
default  under  any  of the  Indenture,  the  Notes  or  the  other  Transaction
Documents; and/or

         (e)  exercise all other rights and  remedies  provided  herein,  in the
Indenture,  the Notes, the other Transaction  Documents or in any other document
or agreement now or hereafter securing all or any portion of the Obligations, or
at law or in equity,  or any combination of any such rights or remedies,  to the
extent permitted by law.

         Upon request by Assignee, Assignor shall assemble and make available to
Assignee  at the Land any of the  Property  which is not  located on the Land or
which has been removed therefrom.

         7.  Additional  Remedies.  If an Event of Default has  occurred  and is
continuing,  in  addition  to all other  rights and  remedies of Assignee as set
forth  under  Section 6 hereof,  Assignee  shall have the  following  rights and
remedies  (together  with the  remedies  set forth under  Section 6 hereof,  the
"Assignment Remedies"):

         (a) Possession and/or Collection of Rent. Assignee, without first being
required to (i) foreclose,  (ii) take any actions to foreclose,  (iii) institute
any legal  proceedings of any kind whatsoever or (iv) exercise any other actions
or remedies hereunder or at law or in equity, shall have the exclusive right and
power  (but not the  obligation)  (A) to enter upon and

                                       5



take possession of the Property or any part thereof,  (B) to rent or re-rent the
same, either in the name of Assignee or Assignor,  or either of them, and/or (C)
to receive all Rents, Issues and Profits from the Property. Assignee shall apply
any Rents,  Issues and  Profits  received by  Assignee  first,  to the costs and
expenses  incurred by Assignee in protecting  and  operating  the Property,  and
next,  to the  payment of the  Obligations  in such  manner and in such order of
priority as Assignee  shall  determine  consistent  with the  provisions  of the
Indenture.  Any such  action by  Assignee  shall not  operate as a waiver of the
Event of Default in question,  or as an  affirmation  of any Tenant Leases or of
the rights of any Tenant in the event title to that part of the Property covered
by the Tenant Leases or held by the Tenant should be acquired by Assignee or any
other  purchaser  at a  foreclosure  sale.  The right of Assignee to receive all
Rents,  Issues and Profits from the Property upon the  occurrence and during the
continuance of any Event of Default shall be applicable  whether or not Assignee
has entered upon, foreclosed, taken any actions to foreclose or taken possession
of the Property, whether or not Assignee has instituted any legal proceedings of
any kind  whatsoever,  or whether or not  Assignee  has  otherwise  attempted to
exercise any other actions or remedies  hereunder or at law or in equity. If any
such Rents,  Issues and Profits  are paid to or received by  Assignor,  Assignor
shall  hold the same in  trust  for  Assignee  and  immediately  pay the same to
Assignee (in the form received,  except for any necessary endorsement),  without
the necessity of any request or demand therefor.  Until receipt from Assignee of
notice  of the  occurrence  of an Event of  Default  hereunder  and  during  the
continuance  thereof, all Tenants of the Tenant Leases and any successors to the
leasehold interest of such Tenants may pay Rents, Issues and Profits directly to
Assignor,  but after notice of the occurrence of any Event of Default and during
the continuance of same,  Assignor covenants to and shall hold all Rents, Issues
and Profits paid to Assignor in trust for Assignee and shall immediately pay the
same to Assignee (in the form received,  except for any necessary  endorsement),
without  the  necessity  of any  request  or demand  therefor.  Assignor  hereby
authorizes  and directs all Tenants of the Tenant Leases herein  described,  and
any  successors to the leasehold  interest of such Tenants,  upon receipt of any
notice from Assignee stating that an Event of Default hereunder has occurred, to
pay to Assignee  the Rents,  Issues and Profits due and to become due under such
Tenant  Leases.  Assignor  agrees that such Tenants shall have the right to rely
upon any such notice and request by Assignee  without any obligation or right to
inquire as to whether an Event of Default  actually  exists and  notwithstanding
any notice from or claim of Assignor to the contrary, and Assignor shall have no
right or claim  against such  Tenants for any such Rents,  Issues and Profits so
paid by the Tenants to  Assignee.  In such event,  receipt by Assignee of Rents,
Issues and Profits from such Tenants or their  successors  shall be a release of
such  Tenants or their  successors  to the extent of all  amounts so received by
Assignee.

         (b) Management.  Subject to the provisions of Section 14, Assignee,  at
its option,  may take over and assume the management,  operation and maintenance
of the Property and perform all acts  necessary  and proper and expend such sums
out of the  income of the  Property  as may be needed  in  connection  therewith
including applying for appropriate  approvals from the Liquor and Gaming License
Authorities,  in the same manner and to the same extent as Assignor  theretofore
might do, including  without  limitation the right to enter into new leases,  to

                                       6


cancel  or  surrender  existing  Tenant  Leases,  to alter or amend the terms of
existing Tenant Leases,  to renew existing Tenant Leases, or to make concessions
to Tenants.  Assignor hereby releases all claims against Assignee arising out of
such management,  operation and maintenance,  including without  limitation such
claims  as may  arise  from  the  negligence  of  Assignee,  but not  the  gross
negligence or willful misconduct of Assignee.

         (c) Receiver.  Upon or at any time after the occurrence of any Event of
Default,  Assignee  shall at once  become  entitled to the  possession,  use and
enjoyment  of the  Property  and the Rents,  Issues and Profits from the date of
such  occurrence and continuing  during the pendency of any proceedings for sale
by the public trustee or foreclosure  proceedings  and the period of redemption,
if any.  Assignee  shall be entitled to a receiver for the Property,  and of the
Rents,  Issues and Profits,  after any such Event of Default,  including without
limitation the time covered by any proceedings for sale by the public trustee or
foreclosure proceedings and the period of redemption,  if any. Assignee shall be
entitled to such receiver as a matter of right,  without  regard to the solvency
or  insolvency of Assignor,  or of the then owner of the  Property,  and without
regard to the value thereof,  and such receiver may be appointed by any court of
competent  jurisdiction upon ex parte  application,  and without notice,  notice
being hereby expressly waived. All Rents, Issues and Profits, income and revenue
therefrom  shall be applied by such  receiver to the payment of the  Obligations
according to the orders and  directions of the court,  or in the absence of such
orders or directions, in the manner set forth in Section 8 below.

         (d)   Attorney-in-Fact.   Assignor   appoints  Assignee  as  Assignor's
attorney-in-fact,  with full authority in the place and stead of Assignor and in
the name of  Assignor,  Assignee  or  otherwise,  from  time to time  after  the
occurrence  of an Event of Default,  to perform,  at  Assignee's  election,  any
action and to execute and record any instrument deemed  necessary,  advisable or
incidental  to accomplish  the purposes of this  Assignment,  including  without
limitation  in  connection   with   exercising  any   Assignment   Remedies  and
effectuating the actions described in this Section 7 and in Section 6 hereof, in
each  instance  only to the  extent  Assignor  has  failed  to  comply  with the
provisions of this Assignment.  Such appointment is irrevocable and coupled with
an  interest  until  payment  in  full  and  complete  performance  of  all  the
Obligations.  Assignee  may  appoint  a  substitute  attorney-in-fact.  Assignor
ratifies  all  actions  taken  by the  attorney-in-fact  but,  nevertheless,  if
Assignee  requests,  Assignor will  specifically  ratify any action taken by the
attorney-in-fact  by executing and delivering to the  attorney-in-fact or to any
entity designated by the attorney-in-fact all documents necessary to effect such
ratification.

          8.   General Provision Pertaining to Remedies.

         (a)  The  Assignment   Remedies  are  cumulative  and  may  be  pursued
concurrently  or  otherwise,  at such  time and in such  order as  Assignee  may
determine, in its sole discretion,  and without presentment,  demand, protest or
further notice of any kind, all of which are expressly waived by Assignor.

                                       7



         (b)  The  enumeration  in  the  Indenture  and  the  other  Transaction
Documents  of  specific  rights and powers  will not be  construed  to limit any
general  rights or  powers  or impair  Assignee's  rights  with  respect  to the
Assignment Remedies.

         (c) If Assignee exercises any of the Assignment Remedies, Assignee will
not be deemed a mortgagee-in-possession.

         (d) Assignee  will not be liable for any act or omission of Assignee in
connection  with the exercise of the Assignment  Remedies  except as a result of
its gross negligence or willful misconduct.

         (e)  Assignee's  right to exercise  any  Assignment  Remedy will not be
impaired by Assignee's delay in exercising or failure to exercise the Assignment
Remedies and will not be construed as extending  any cure period or constitute a
wavier of the default or Event of Default.

         (f) If an Event of Default occurs,  Assignee's or a receiver's  payment
or  performance  of  acceptance of payment or  performance  will not be deemed a
waiver or cure of the Event of Default.

         (g) Assignee's or a receiver's  acceptance of partial  payment will not
extend or affect any grace  period or  constitute a waiver of a default or Event
of Default but will be credited against the unpaid Obligations.

         (h) If Assignee or a receiver exercises any of the Assignment Remedies,
such action will not cure or waive any default, will not waive, modify or affect
any notice of default under the  Transaction  Documents and will not  invalidate
any act done  pursuant to a notice of default under the  Transaction  Documents.
Once Assignee  exercises the Assignment  Remedies,  Assignee's  enforcement will
continue for so long as Assignee elects, notwithstanding that the collection and
application  of the  Rents,  Issues  and  Profits  may have  cured the  original
default.  If Assignee  elects to  discontinue  the  exercise  of the  Assignment
Remedies, the Assignment Remedies may be reasserted at any time and from time to
time following a subsequent Event of Default.

         (i) A demand by  Assignee  or a  receiver  on any  Tenant to pay Rents,
Issues and Profits to Assignee or the  receiver by reason of an Event of Default
will be  sufficient  notice to such  Tenant to make  future  payments  of Rents,
Issues and Profits to Assignee or the receiver without the necessity for consent
by Assignor.

         9. Application of Income.  Assignee shall,  after payment of all proper
charges and expenses, including reasonable compensation to any managing agent as
it shall  select and  employ,  and after the  accumulation  of a reserve to meet
taxes,  assessments  and insurance as herein  required or under the Indenture or
the other Transaction  Documents in requisite amounts,

                                       8


credit the net amount of income  received  by it from the  Property by virtue of
this absolute  assignment  to any amounts due and owing to it by Assignor  under
the terms hereof,  but the manner of the application of said net income and what
items shall be  credited  shall be  determined  pursuant  to the  Indenture,  or
otherwise in the sole  discretion  of  Assignee.  Without  impairing  its rights
hereunder,  Assignee  may,  at its  option,  at any time and from  time to time,
release to Assignor  Rents,  Issues and Profits  received  by  Assignee,  or any
portion of such Rents, Issues and Profits.  Assignee shall not be liable for its
failure to collect,  or its failure to exercise  diligence in the  collection of
Rents,  Issues and Profits,  but shall be accountable only for Rents, Issues and
Profits that Assignee shall actually receive.  Assignee shall not be accountable
for more monies  than it actually  receives  from the  Property  nor shall it be
liable for failure to collect Rents, Issues and Profits.

         10.  Term.  This  absolute  assignment  shall  remain in full force and
effect so long as the Obligations or any part thereof to Assignee remains unpaid
or unsatisfied, in whole or in part.

         11.  Actions of  Trustee.  All  provisions  hereof  shall  inure to the
benefit of and all actions authorized  hereunder shall be exercisable by Trustee
or any substitute Trustee at Assignee's request.

         12.  Duty to Defend.  If  Assignor  or any of its  trustees,  officers,
participants,  employees,  agents  or  affiliates  is a party in any  proceeding
relating  to this  Assignment  or the  Tenant  Leases  and the Rents  Issues and
Profits,  Assignor will defend and hold  harmless such party with  attorneys and
other  professionals  retained by Assignor  and  approved  by  Assignee.  At its
option,  Assignee  may  engage its own  attorneys  and other  professionals,  at
Assignor's  expense,  to  defend  or  assist  such  party.  In any  event,  such
proceeding will be controlled by Assignee.

         13.  Payment of Expenses.  Assignor is obligated to pay all  reasonable
expenses  incurred by Assignee or any receiver or that are otherwise  payable in
connection with this  Assignment or the Tenant Leases and the Rents,  Issues and
Profits, including without limitation expenses relating to (i) any proceeding or
other claim asserted against Assignee arising under this Assignment and (ii) the
preservation of Assignee's security and the exercise of any Assignment Remedies.

         14.  Gaming  Laws.  The grant of,  and terms and  provisions  of,  this
Assignment,  including,  but not limited to, all rights and remedies of Assignee
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 Assignee 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.

         15.  Supplementary  Assignment.  This  Assignment  is  intended  to  be

                                       9



supplementary  to and not in substitution for or in derogation of any assignment
of rents contained in the Deed of Trust.  Failure of Assignee to avail itself of
any of the terms,  covenants or conditions of this  Assignment for any period of
time or for any reason shall not constitute a waiver thereof.

         16. Notices. All notices and other communications under this Assignment
shall be in writing, except as otherwise provided in this Assignment.  A notice,
if in writing, shall be considered as properly given if given in accordance with
the provisions of Section 5.8 of the Deed of Trust.

         17. No Waiver of Remedies.  By accepting  payment of any amount secured
hereby after its due date,  or an amount which is less than the amount then due,
or performance of any obligation  required hereunder after the date required for
such performance, Assignee does not waive its right to require prompt payment or
performance  when due of all other  amounts  or  obligations  so  secured  or to
declare a default by reason of the failure to so pay or perform.

         18. Captions. The captions or headings at the beginning of each Section
hereof are for the  convenience  of the parties and are not to be construed as a
part of this Assignment.
