                                   L E A S E

     THIS LEASE is made and entered into this 4th day of March, 1976, by and
between A.W. HAM, JR., Trustee under the Wills of A.W. Ham and Alta H. Ham,
deceased, hereinafter referred to as Lessor, and NEVADA BUILDING COMPANY, a
partnership comprised of Fredric N. Richman and Allan D. Sachs, hereinafter
referred to as Lessee.

                                  WITNESSETH:

     That the Lessor, for and in consideration of the rents hereinafter
specified to be paid by the Lessee, and the covenants and agreements hereinafter
contained, by the Lessee to be kept and performed, has demised and let unto said
Lessee those certain premises in the City of Las Vegas, County of Clark, State
of Nevada, described as follows, to wit:

     Lots Five (5) and Six (6) of Block
     Thirty (30), Clark's Las Vegas Townsite.

     TO HAVE AND TO HOLD unto the said Lessee for a term of 62 years and 7
months, commencing on June 1, 1976, and ending December 31, 2038, unless sooner
terminated under the provisions hereinafter contained; and the said Lessee
hereby covenants and agrees to pay to said Lessor as rent for said premises the
sum of $4,000 per month during the first three years of this Lease and the sum
of $7,500 per month during the remaining term of this Lease.



                               EXHIBIT "A" PAGE 1

     All rentals shall be payable monthly in advance to said Lessor. Provided
further that as additional rent Lessee agrees to pay to Lessor such sums as
represent any and all real property taxes and assessments levied against the
real property leased hereunder, said sums to be due and payable to the Lessor
no later than twenty (20) days prior to the due date of such taxes and
assessments, provided that Lessor sends copies of all tax and assessment bills
to Lessee. Should the periods to which the foregoing rentals apply not
correspond with full calendar months, such rentals shall be appropriately
prorated.

     In the event any governmental authority shall levy an assessment or tax
which, by its term, provides that the same may be paid in installments, it is
understood and agreed the Lessee shall pay the same but not be required to pay
said assessment in its entirety, but rather may elect to pay over the maximum
allowable period those installments falling due within the term hereof.

     Beginning with the twelve month period commencing August 1, 1978, and each
twelve months thereafter, the monthly rental provided for above shall be
increased by a percentage equal to the percentage by which the consumer price
index of the United States Department of Labor, Bureau of Labor Statistics,
United States Index, as of the beginning of the subject calendar year exceeds
said Index as of the end of 1975.

     Lessor shall give written notice to Lessee of additional rental due
hereunder, setting forth said price indexes as published and showing
computation of rental.

                                      -2-

                               EXHIBIT "A" PAGE 2


<PAGE>
     Payment of said rental as above provided shall be made to A.W. HAM, JR.,
Trustee, at his office in Las Vegas, Nevada, or such other place as Lessor may
from time to time designate in writing.

     Receipt is hereby acknowledged by the Lessor of the sum of Four Thousand
Dollars ($4,000.00) as payment of the first month's rental.

     In the event the aforesaid price index shall cease to be published during
the term of this lease, then and in such event only the adjustment of rentals
therein provided shall be made on the basis of such other comparable index as
shall be then published by the United States Government or, if there be none,
by the comparable index published by Standard & Poor's. In the event none of
the foregoing indexes is published, it is understood and agreed that a Board of
Arbitrators shall be constituted annually to decide the percentage of
adjustment applicable to the rentals herein specified, based upon their
examination of retail prices in the United States, unless the parties hereto
shall themselves be in agreement as to the amount of said adjustment.

     Said Board of Arbitrators shall consist of three (3) disinterested
persons. Each party hereto shall appoint one (1) arbitrator and the two (2)
appointed arbitrators shall appoint the third. Said Board of Arbitrators shall
begin at once and proceed with all reasonable dispatch to determine the
questions referred to them as herein provided, and their determination shall in
each and every instance be final and binding on the parties hereto. If either
party hereto at any time prefers to have the adjustment of rental

                                      -3-
                               EXHIBIT "A" PAGE 3
<PAGE>
determined by the courts instead of by arbitrators, the same may be done by the
party having such preference beginning legal proceedings in any year prior to
the appointment of the arbitrators, but not afterward.

     Said Board of Arbitrators shall report to the parties hereto within fifteen
(15) days after the rental adjustment question has been submitted to them, and
their findings shall be in writing, signed by not less than two (2)
arbitrators. If any one or more of said arbitrators shall resign, die, or
become incapacitated before a full and final determination be arrived at, the
said arbitrator shall be replaced in the same manner as he was originally
appointed and shall have the same power and authority as though he had been
originally appointed. The parties hereto shall share equally the cost and
expense of said arbitrators and all expenses connected therewith.

     It is mutually agreed that this Lease is given, made and executed upon the
following terms, restrictions, conditions and covenants, each and all of which
the Lessee hereby acknowledges to have read, and with each and every one of
which the Lessee agrees to comply, to wit:

made by Lessee hereunder. Lessee may assign this Lease or any portion thereof.

     Lessee shall have the right to demolish, wreck or remodel the building

premises and thereafter construct a new or remodeled building. Said new or
remodeled building shall conform to plans and specifications prepared by a
licensed architect and shall be in accordance with all local or state zoning
ordinances. It is further understood that if Lessee demolishes, wrecks or
remodels said building, that the aforesaid new or remodeled building may be a
hotel and/or gaming casino on said premises provided that same shall be in
accordance with applicable laws. Within the hotel and/or gaming casino, Lessee
shall have the right to operate any type of gaming sanctioned by the laws of
the State of Nevada.

     Before Lessee shall commence to wreck the building now upon said premises,
and before Lessee shall commence to construct said new building, Lessee will
execute and deliver to Lessor an indemnity bond in a sum equal to the
architect's estimate of the cost of wrecking the building and the completion of
a new building which bond shall be executed by Lessee as principal; and by a
responsible surety company authorized to do business in the State of Nevada as
surety or by other surety or sureties satisfactory to Lessor. Said bond shall
be conditioned for performance by the Lessee of all agreements contained in
this Lease, said bond to be discharged by Lessor upon the completion of said
wrecking work and erection of said new building, free and clear of all liens
and the expiration of the time within which liens therefor could be asserted.

     In the wrecking of said buildings and in the construction of a new
building, Lessee will fully

protect Lessor against any lien or rights to liens and from any claims of
contractors, subcontractors, mechanics, laborers, materialmen or any other
persons and any and all other liens or claims of lien by reason of the wrecking
of said building or construction of a new building, and Lessee agrees to save
Lessor harmless from and hereby indemnifies Lessor against any and all injury
and loss which Lessor may suffer by reason of any such lien, right or claim;
including attorney's fees, court costs and expenses.

     2. Said Lessee covenants and agrees that it has examined and knows the
condition of the premises and every part thereof and that no statements or
representations as to condition or repair of said premises have been made by
said Lessor or any person for him prior to or upon the execution of this Lease,
and that Lessee accepts said premises in their present condition, waiving any
claim or right on account of such condition, and the Lessor shall not be liable
to the Lessee or his successors or assigns or to any person for any injury or
damage that may result to persons or property because of any defect in the
construction or condition or present or future lack of repair of said premises,
including all plumbing in, about, upon or under said premises; and said Lessee
agrees that during said term Lessee will, at his own expense, keep all and every
part of said premises and the appurtenances, including adjoining streets and
alleyways or courts, if required by city ordinances, in good order and repair,
and in clean and wholesome condition, free from dirt and accumulation of waste,
all such maintenance to be in compliance with all

                                      -6-

                               EXHIBIT "A" PAGE 6

applicable city ordinances, and will not commit or allow any waste or misuse of
the premises, plumbing, water, light, power or fixtures, and will pay for all
damage to the building or other tenants or occupants thereof caused by such
waste, misuse or neglect of said premises, its appurtenances or its apparatus
therein contained, and that said Lessee may make any change, alteration or
addition in or to said demised premises without the written consent of the
Lessor first had and obtained, so long as the premises are improved thereby, and
that at the expiration of the term mentioned in this Lease, or at the sooner
termination thereof by forfeiture or otherwise, said Lessee will yield up and
deliver said demised premises, together with all their appurtenances leased
hereunder, to said Lessor in good order and condition, damage by the elements
and ordinary wear excepted, and will surrender to the Lessor all the keys to
the several doors and such other things as may appertain to said demised
premises. Nothing, however, in the foregoing shall be construed to require
Lessee to replace, repair or rebuild the leased premises in the event the same
are condemned for public use by duly constituted governmental authority. It is
understood that in the event such condemnation shall occur, that the
obligations of the Lessee under this Lease shall not be changed.

          3.   Lessor shall not be called upon to make any alterations,
improvements or repairs whatsoever on the premises, or any part thereof, or
the appurtenances.

               Lessor shall not be held liable for any temporary failure of any

the building or the premises herein demised, nor for the failure of the supply
of water, nor for a supply of gas, water, steam, sewer or other pipe, or water
closet, tank or other fixtures, nor for the annoyance, inconvenience or damage
caused by any electric or other wire, whether upon said demised premises or in
other parts of the building or adjoining buildings, nor for any damage caused by
water coming or being upon said premises through the roof, trapdoor, skylight
or otherwise, nor for any damage arising from any act or neglect of any other
tenants or occupants of the building, nor for any loss or injury to the
property or the person of Lessee or any occupant of said demised premises from
any cause whatsoever.

          4.   Lessee shall pay all heat, light, power, water, telephone
service and all other utility, sewer rental, or garbage or trash disposal
charges on the premises or assessed against the property.

          5.   It is further understood and agreed that during the term of this
Lease, Lessee, at his own expense, shall secure and carry on the building
leased hereunder, fire insurance in an amount equal to the full insurable value
of said building at the time such insurance is written or renewed, as
determined by an appraiser approved by the Board of Fire Underwriters, said
insurance policies to be delivered to and proceeds payable to Lessor and
Lessee, as their interest may appear. In addition to said fire insurance, the
Lessee hereby agrees to keep and maintain at all times during the term of this
lease public liability insurance in an amount that is usual and customary for
similar structures and occupancies in the City of Las Vegas, Nevada, but in


                                      -8-

<PAGE>
no event less than $500,000/$1,000,000 for person or persons injured in or from
the premises, which insurance shall be written in form to protect Lessor and
Lessee from any and all claims or damages which may arise from the operation of
business within the said premises, and the same to be carried with a company or
companies approved by Lessor. In connection therewith, a certificate of such
insurance shall be delivered to Lessor within fifteen (15) days following the
execution of this Lease. Lessor agrees to assign, at Lessee's option, all
policies of insurance covering the premises, and the premiums shall be prorated
as of the date of assignment.

      All fire insurance money received shall be held by the BANK OF NEVADA, in
trust, for the purpose of defraying the cost of rebuilding or repairing the
building damaged or destroyed and for the purpose of paying to Lessee any
excess thereof after the work of rebuilding or repairing, as the case may be,
shall have been completed and fully paid for; except that nothing in the
foregoing shall be construed to alter the provisions of paragraph 9 below, and
in the event of a lease termination under the provisions of said paragraph,
Lessor shall be entitled to all insurance proceeds received, it being
understood and agreed that Lessor shall at no time be required to pay for any
building or repair expenses.

      Lessor reserves the right to attach to said policy or policies such
mortgage clauses as may be required by any lending agency in connection with
any loan secured by the leased premises, but agrees that all insurance money
received by Lessor shall be available for the purpose of defraying the cost of
rebuilding and repairing, as the case may be, of the building so injured or
destroyed. The same shall be paid out from time to time for labor and materials.


                                      -9-

and other proper items of building cost performed or supplied toward the work
of repair and reconstruction, and provided that the payments of principal and
interest shall at no time be greater than the rental payments due hereunder,
and the Lessee may make said payments of principal and interest to such lending
agency, deducting them from the rentals.

      In the event of fire or other casualty, Lessee and his subtenants, if
any, shall in no case be entitled to compensation or damage on account of any
inconvenience or annoyance in making said repairs, or any other cause.

      6. Said Lessee agrees that he will not keep or allow to be kept upon said
premises any gasoline, distillate or any kind of petroleum products, nor any
other substance or material of an explosive or inflammable nature which will
cause an increase in the rate of insurance thereon, nor will Lessee allow said
premises to be used for any purpose which will cause such increase in insurance
rates, unless Lessee shall pay for such additional premium, or which will make
void or voidable any policy for such insurance, nor any purpose which will
conflict with any of the city ordinances of Las Vegas, Nevada, which may now be
in force or hereafter adopted, nor permit said premises to be used in any
manner which will injure the reputation of the same or of the building of which
they are a part, or disturb or injure the tenants of such building or
neighborhood.

      7. Lessee covenants and agrees to pay promptly, before delinquency, all
taxes, assessments and other charges which may be levied, assessed or charged
against its trade

fixtures, inventory, cash or other property belonging to Lessee or his
sublessees, if any, and used upon the demised premises.

     8.   If any petition in bankruptcy, voluntary or involuntary, be filed, or
if any adjudication of bankruptcy or insolvency be rendered against the Lessee,
or if a receiver of the business or assets of the Lessee should be appointed,
or Lessee shall make an assignment for the benefit of creditors, or if any sale
or attempted sale of the leasehold interest hereby created shall be made under
or by virtue of any execution or other judicial process, the Lessor shall have
the right immediately to terminate this Lease, and no person shall have the
right to use, possess or occupy the said premises by virtue thereof.

     9.   It is further expressly understood and agreed that time is of the
essence in the performance of each and all of the provisions and covenants of
this Lease, and each and all of the provisions and covenants of said  Lease are
conditions precedent to be faithfully and fully performed and observed by the
said Lessee to entitle the Lessee to continue in possession of the said
premises; that if default shall be made in the payment of the rent
hereinbefore specified to be paid, thirty (30) days after written demand, or
thirty (30) days after written demand if default shall be made in any of the
covenants or agreements herein contained to be kept by Lessee, it shall be
lawful for said Lessor, at his election, to declare said term ended, and to
reenter the said demised premises or

                                      -11-

any part thereof and to expel, remove or put the Lessee or any person or
persons keeping or being in or upon the same together with all goods and
chattels found therein, using such force as may be necessary in so doing, and
to repossess and to enjoy said premises again as of his first and former
estate. And if, at any time, said term shall be ended at such election of said
Lessor, as aforesaid, or any other way, the said Lessee hereby covenants and
agrees to surrender and deliver up the said above demised premises and property
peaceably to said Lessor immediately upon such termination aforesaid; and if
the said Lessee shall remain in possession of said premises after said
termination of this Lease, in any of the ways herein named, said Lessee shall
be deemed guilty of an unlawful detention of said premises under the statute,
and shall be subject to all the conditions and provisions above named, and, to
eviction and removal at any time thereafter. All of the foregoing remedies are
cumulative and are given without impairing any other rights or remedies of the
Lessor. It is further expressly understood and agreed that the waiver by Lessor
of any default on the part of the Lessee if the prompt payment of any
installment or installments of rent or in the observance, payment or
performance of any of the provisions, terms or conditions hereof, shall not be
deemed to be a waiver of the right of Lessor to treat any other or subsequent
default as operating to forfeit said Lease, and any such waiver shall not be
deemed to excuse said Lessee in the prompt payment of any other installment or
the prompt and faithful performance of the same or any other covenant in the
future.

                                      -12-

     10. If the Lessee shall be in default in the payment of rent and shall
vacate or abandon said premises or any part thereof (and absence of the Lessee
therefrom for a period of thirty (30) days after notice given by Lessor pursuant
to paragraph 9 above shall be considered such an abandonment thereof), the
Lessor may, if he so elects, and without further demand or notice, reenter said
premises and remove the contents and take possession of said premises and relet
the same or any part thereof at such rental and upon such terms and conditions
as he may deem proper, and apply the proceeds thereof, less the reasonable
expenses, including the usual agent's commissions so incurred, upon the amount
due from Lessee hereunder, and the Lessee shall be liable for any deficiency. If
the Lessor shall take possession of said premises and relet the same, such
reletting shall not operate as a termination of this Lease unless the Lessor so
elects, such election to be evidenced by written notice to the Lessee, nor shall
such action by the Lessor operate as a waiver of any other rights or remedies of
the Lessor hereunder.

     11. It is agreed that in the event the Lessee shall make alterations or
additions to the leased premises that the same shall meet all provisions
applicable to zoning, building, safety and other governmental requirements. It
is further agreed that in the event such work is done by Lessee or his
sublessees, if any, on the premises, Lessor reserves the right to post notice of
nonresponsibility and/or to record the same in connection therewith.

     12. In the event either Lessor or Lessee employs an attorney to enforce the
terms, covenants or conditions


                                      -13-

     Each party shall have the right to amend said address by giving to the
other party at least fifteen (15) days' notice thereof, in writing.

Lessee shall, upon the request of the other, execute a skeleton form of lease

and effect.
