                  WHEREAS,  the Company and the Bank  entered  into that certain
Letter of Credit and  Reimbursement  Agreement dated as of February 7, 1991 (the
LC AGREEMENT;  all capitalized  terms used but not defined herein shall have the
respective meanings assigned to them in the LC Agreement); and

                  WHEREAS, the LC Agreement required the Initial Disbursement to
occur on or prior to February 7, 1992; and

                  WHEREAS, the conditions to the Initial Disbursement enumerated
in the LC Agreement were not fulfilled in all respects by February 7, 1992; and

                  WHEREAS, the Bank has determined,  with the concurrence of the
Company,  that the aggregate amount of undisbursed Bond Proceeds is insufficient
to  pay  the  aggregate  of the  cost  of  completing  the  Construction  of the
Improvements and the other costs contemplated in the Budget, and that the amount
required to eliminate such insufficiency is $24,000,000; and

                  WHEREAS,  pursuant to Paragraph 9(k) of the LC Agreement,  the
Bank has



 













required,  as a condition to the Initial  Disbursement,  that the Company and/or

Amount); and

                  WHEREAS,  a  portion  of the Loan  Balance  Amount  represents
amounts  previously  expended  by the  Borrower  and with  respect  to which the
Borrower is entitled to reimbursement; and

                  WHEREAS,  WKA and KGC have determined to each provide one-half
of the Loan Balance Amount as equity and/or a loan to the Company; and

                  WHEREAS,  in order to finance a portion of such contributions,
WKA and KGC shall together  borrow the amount of $8,000,000 from GDB on the date
hereof, pursuant to a Credit Facility Agreement dated the date hereof among GDB,
WKA and KGC (the GDB Additional Loan Agreement); and

                  WHEREAS, in consideration of the Bank's agreement to allow the
Initial  Disbursement to occur after February 7, 1992, the Company has agreed to
certain changes in the terms and conditions to the LC Agreement.

                                        2





 













                  COMPLETION DATE shall mean October 12, 1993.

                  GUARANTIES  shall mean the (i)  Environmental  Indemnity,  the

                  GUARANTORS shall mean KIUSA, KGCC, KGC, Williams and WKA.

                  INITIAL  DISBURSEMENT  shall mean the initial  disbursement by
the  Bank of the  funds  held by the Bank  pursuant  to  Section  9(k) of the LC
Agreement.

                  SUBSTANTIAL COMPLETION shall mean the occurrence of all of the
following  events:  (i) the completion of the  Construction of the  Improvements
(excluding  punchlist  items)  in  accordance  with all Legal  Requirements  and
substantially  in accordance with the Plans as to any aspect of Construction and
the issuance of applicable use or occupancy permits therefor satisfactory to the
Bank;  (ii) the  delivery  to the  Bank of  certificates,  in form  and  content
satisfactory  to the Bank,  from the  Company,  the  Architects  and the  Bank's
Consultant  to the  effect  that  all  of  the  work  required  to be  performed
substantially  to  complete  the  Improvements  in  accordance  with  all  Legal
Requirements and in accordance with the Plans has been performed;  and (iii) the
Commencement Date under the Management Agreement.

                  2. The Annual  Letter of Credit Fee shall be increased by .20%
per  annum  through  the Date of  Substantial  Completion  and by .30% per annum
thereafter,  so that the  percentages  1.25%,  1.05%  and .90%  which  appear in
Section  2(b) of the LC  Agreement  shall be changed to 1.45%,  1.35% and 1.20%,
respectively.

                  3. The Bank  consents  to the  execution  and  delivery of the
Amendment  to Venture  Agreement.  Accordingly,  the first  three  sentences  of
Section 7(ii) of the LC Agreement


                                        3





 













are amended in their entirety as follows:

                           (ii)  Deficiency  Loans.  Any funds  advanced  to the
         Company as  Deficiency  Loans (as  defined in the  Company  Partnership
         Agreement),  whether  or not at the  direction  of the  Bank,  shall be
         applied only to the operating costs or other fees and expenses  related
         to the operation of the Project; provided,  however, that the foregoing
         restriction  shall be of no effect  from and after the  Coverage  Date.
         After the Date of  Substantial  Completion and until the Coverage Date,
         the Bank will have the right to cause the Company,  acting through WKA,
         (A) at  such  times  as the  Bank  shall  determine  in the  reasonable
         exercise of its judgment that an Operating  Deficit exists with respect
         to any month, to require the General  Partners to make Deficiency Loans
         in  amounts  of up to  $14,000,000  in the  aggregate  (less  any  such
         Deficiency  Loans  for such  purpose  which  may have  previously  been
         voluntarily  advanced),  and (B) to apply such funds on account of such
         Operating  Deficits.  The Bank shall have no right to cause  Deficiency
         Loans to be made to pay principal  under the Bonds,  the Loan Agreement
         or  hereunder.  Notwithstanding  anything  in the  Company  Partnership
         Agreement  to the  contrary,  neither  the  Deficiency  Loans  nor  the
         operating  reserve  line item of the Budget may be used for the purpose
         of paying principal or interest under the GDB Additional Loan.

                  4. From and after  the date on which  Deficiency  Loans in the
aggregate  amount of  $14,000,000  have been made and  applied to the payment of
Operating  Deficits and until the Coverage Date, if the Bank shall  determine in
the reasonable  exercise of its judgment that further Operating Deficits (which,
for the purposes of this  Paragraph 4, shall not include debt service on the GDB
Loan or any Special Loans (as defined in the Company Partnership


                                        4





 













Agreement))  exist with  respect to any month,  the Bank may require (i) each of
WKA and KGC to make additional loans to the Company in the amount of one-half of
such Operating Deficits,  and (ii) the Company to apply such funds on account of
such Operating Deficits;  provided,  however, that the obligation of each of WKA
and KGC to make such  additional  loans  shall be limited to  $3,000,000  in the
aggregate (so that the total amount of such additional loans required to be made
by the Bank shall not exceed $6,000,000 in the aggregate).  If the Bank requires
any such loans to be made, the Company hereby irrevocably directs WKA and KGC to
pay the proceeds of such loans at the direction of the Bank for  application  to
such  Operating  Deficits.  The  failure  by WKA  and/or  KGC to make  any  such
additional  loans  shall  constitute  a  default  under  the LC  Agreement.  The
obligations of WKA under this  Paragraph 4 shall be severally  guarantied by WMS
Industries,  Hugh  Andrews and Burton I.  Koffman and  Richard E.  Koffman  (the
ADDITIONAL   LOAN   GUARANTORS)   pursuant   to   guaranties   to  be   executed
contemporaneously herewith. It shall be deemed an Event of Default if (i) any of
the events  described in clauses (v), (vi), (vii) and (viii) of Section 12(a) of
the LC  Agreement  shall  occur  with  respect  to any  of the  Additional  Loan
Guarantors, and (ii) the Company fails to provide the Bank, within 60 days after
the event in question,  with reasonably  acceptable  collateral or guaranties to
replace the guaranties of the Additional  Loan  Guarantors  with respect to whom
such event occurred.

                  5.  Simultaneously  herewith,  GDB shall fully advance the GDB
Additional  Loan, and WKA and KGC shall deposit the Loan Balance Amount with the
Bank in the following manner:  $3,538,705.36,  representing  amounts  previously
expended by the Borrower on account of Total Project Costs,  shall be paid to or
at the Borrower's direction;  $3,560,966.34,  representing the remaining portion
of the Initial Disbursement, shall be disbursed


                                        5





 













in accordance  with the Request for  Disbursement  approved by the Bank; and the
balance of the Loan Balance Amount  $16,900,298.30) shall be paid to the Bank by
wire transfer.  The Bank shall hold the Loan Balance Amount in an account at the
Bank, which account shall bear interest at a fluctuating rate per annum equal to
the  Eurodollar  Time  Deposit  Rate.  The Line  Item for  Contingency  shall be
increased by the amount of any interest earned on the Loan Balance  Amount.  All
such interest shall be added to and become part of the Loan Balance Amount, and,
to the extent not disbursed to pay Project  Costs,  shall be released to WKA and
KGC upon Substantial  Completion of the Project.  The Loan Balance Amount may be
commingled  with the Bank's general funds.  Notwithstanding  anything in Section
9(k)  of the LC  Agreement  to the  contrary,  the  Bank is  hereby  irrevocably
authorized  and directed by the  Company,  WKA and KGC to apply the Loan Balance
Amount to the costs of the first  Disbursements  for Hard  Costs and Soft  Costs
approved by the Bank,  without  regard to the  particular  Line Item(s) to which
such costs  relate,  before the Bank shall direct and  authorize  the Trustee to
disburse proceeds of the Loan to pay such costs. Upon each such application of a
portion of the Loan Balance Amount,  a  corresponding  amount shall be deemed to
have  been  loaned  by WKA and KGC to the  Company.  Unless  and  until the Loan
Balance  Amount  is  so  applied,  the  Loan  Balance  Amount  shall  constitute
additional  security  for WKA's and KGC's  obligations  under  their  respective
Completion  Guaranties  and for the  Company's  performance  of its  obligations
pursuant to this Agreement (a security  interest  therein being hereby created).
The parties agree that the first $8,000,000 of the Loan Balance Amount disbursed
by the Bank shall be deemed to be the  proceeds  of the loan from WKA and KGC to
the Company.


                                        6





 













                  6. The Bank confirms that the Initial  Disbursement  is taking
place on the date hereof, notwithstanding that the Initial Disbursement is being
funded with a portion of the Loan Balance Amount rather than with Bond Proceeds.

                  7. The Company shall agree to promptly recommence construction
of the Project, so that the following  construction  activities will commence on
or before the dates listed below:

                  -        Begin wall footings for the Cliftop remodeling -- May
                           30, 1992.

                  -        Begin   Elect/Mech.   underground   for  Cliftop  new

                  -        Begin  mobilization for Convention  Center -- May 15,

                  -        Begin footing excavation for Convention Center -- May

                  -        Begin  mobilization for Hotel  core/casino -- May 15,
                           1992.

                  -        Begin  footing  for  Panoramic  Elevator at the Hotel
                           core/casino -- May 30, 1992.

                  -        Begin footing  excavation  for Harborside -- June 30,
                           1992.

Failure to comply  with the  foregoing  requirements shall  constitute  an Event
of  Default  under the LC Agreement.

                  8. The Bank confirms that it has approved the execution by the
Company of the Trade  Contracts  described  on Schedule A annexed  hereto in the
form presented by the Company to the Bank's Consultant.

                  9.  The  following  is  added  to  Paragraph  12(a)  of the LC
Agreement:

                      (xxiii) if any Event of Default  relating  to the  Project
                              shall occur under the


                                        7





 













                             GDB  Loan  Agreement  or the  Additional  GDB  Loan
                             Agreement.

                  10. WKA and KGC agree to use their  respective best efforts to
assist the Bank in  obtaining  participants  for the Bank's  interest  in the LC
Agreement and the Letter of Credit.

                  Except as amended  hereby,  the LC  Agreement  remains in full
force and effect.

                  This Agreement may be executed in one or more counterparts.

                  IN WITNESS  WHEREOF,  the  parties  hereto  have  caused  this
Amendment to be duly executed and delivered by their  respective duly authorized
