                 REVIEW REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS


To the Mohegan Tribal Gaming Authority:


We have reviewed the accompanying condensed balance sheet of Mohegan Tribal
Gaming Authority ("Authority") as of June 30, 1997, and the related condensed
statements of income and capital for the three months ended June 30, 1997, and
for the period October 12, 1996 (date of commencement of operations) through
June 30, 1997, and the related condensed statements of cash flows for the period
October 12, 1996 (date of commencement of operations), through June 30, 1997. 
These condensed financial statements are the responsibility of the Authority's
management.

We conducted our review in accordance with standards established by the American
Institute of Certified Public Accountants.  A review of interim financial
information consists principally of applying analytical procedures to financial
data and making inquiries of persons responsible for financial and accounting
matters.  It is substantially less in scope than an audit conducted in
accordance with generally accepted auditing standards, the objective of which is
the expression of an opinion regarding the financial statements taken as a
whole.  Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any material modifications that should
be made to the financial statements referred to above for them to be in
conformity with generally accepted accounting principles.

We have previously audited, in accordance with generally accepted auditing
standards, the condensed balance sheet of Mohegan Tribal Gaming Authority as of
September 30, 1996, and the related cash flow for the year then ended (not
presented herein), and, in our report dated November 27, 1996, we expressed an
unqualified opinion on those financial statements.  In our opinion, the
information set forth in the accompanying condensed balance sheet of Mohegan
Tribal Gaming Authority as of September 30, 1996, is fairly stated, in all
material respects, in relation to the balance sheet from which it has been
derived.

                     NOTES TO CONDENSED FINANCIAL STATEMENTS
                                  JUNE 30, 1997
                                   (UNAUDITED)


BASIS OF PRESENTATION:

The Mohegan Tribal Gaming Authority (the "Authority"), established on July 15,
1995, is an instrumentality of the Mohegan Tribe of Indians of Connecticut (the
"Tribe").  The Authority commenced operation of the gaming and entertainment
facility (the "Mohegan Sun") on October 12, 1996.

Prior to October 12, 1996, the Authority was classified as a Development Stage
enterprise as defined by Statement of Financial Accounting Standards No. 7.

The Authority has engaged Trading Cove Associates ("TCA") to manage the
development, construction and operation of the Mohegan Sun.  TCA is 50% owned by
Sun Cove Ltd., an affiliate of Sun International Hotels Limited ("Sun
International"), and 50% owned by Waterford Gaming, LLC.

The condensed financial statements have been prepared in accordance with the
accounting policies described in the Authority's 1996 Annual Report on Form 10-K
and should be read in conjunction with the Notes to Condensed Financial
Statements which appear in that report.  The condensed Balance Sheet at
September 30, 1996, contained herein was derived from audited financial
statements, but does not include all disclosures contained in the Form 10-K and
applicable under generally accepted accounting principles.

Certain amounts in the condensed financial statements have been reclassified. 
The reclassification has no effect on net income.

In the opinion of the Authority, all adjustments, consisting only of normal
recurring adjustments, necessary for a fair presentation of the results for the
interim periods have been included.  The results reflected in the condensed
financial statements for the third quarter of 1997 are not necessarily
indicative of expected results for the full year, as the casino industry in
Connecticut is seasonal in nature.
 
The Authority's operation of a casino in Connecticut is subject to significant
regulatory controls which affect virtually all of its operations.

2.  LONG-TERM DEBT:

Long-term debt consists of the following:

2.  LONG-TERM DEBT CONTINUED:

A.   On September 29, 1995, the Authority issued $175 million in Senior Secured
Notes due 2002 (the "Senior Notes") with fixed interest payable at a rate of
13.50% per annum and Cash Flow Participation Interest, as defined, in an
aggregate amount of 5.0% of the Authority's Cash Flow up to a limit, during any
two consecutive semi-annual periods, ending September 30, of $250 million of the
Authority's Cash Flow.  Fixed interest is payable semi-annually and commenced
May 15, 1996. The aggregate amount of Cash Flow Participation Interest payable
will be reduced pro rata for reductions in outstanding principal amount of
Senior Notes.  The payment of Cash Flow Participation Interest may be deferred
if the Authority's Fixed Charge Coverage Ratio is less than 2 to 1 for the four
prior consecutive quarters.  The Senior Notes are redeemable at set prices as
set forth in the Senior Notes after November 15, 1999, at the option of the
Authority.  Upon the occurrence of certain events (as specified in the Indenture
for the Senior Notes) each holder of Senior Notes can require the Authority to
repurchase the notes at prices specified in the Senior Notes.  Beginning with
the fiscal year ending September 30, 1997, the Authority will be required, under
certain circumstances, to offer to purchase, at set prices, certain amounts of
Senior Notes then outstanding.

B.   The Authority obtained $90.0 million of subordinated financing from Sun
International and Waterford Gaming LLC in the form of notes (the "Subordinated
Notes").  The Authority issued $20.0 million of  Subordinated Notes to each of
Sun International and Waterford Gaming LLC, which notes bear interest at 15.0%
per year, payable semi-annually.  Interest on the Subordinated Notes is being
deferred and will not be paid until at least half of the Senior Notes have been
retired (or offered to be retired, pursuant to the terms of the Indenture
governing the Senior Notes) and certain other conditions have been fulfilled. 
The Authority also issued $50.0 million in Subordinated Notes to Sun
International evidencing draws made by the Authority under the $50.0 million
secured completion guarantee provided by Sun International (the "Secured
Completion Guarantee").  Each Subordinated Note issued under the Secured
Completion Guarantee bears interest at the rate per annum then most recently
announced by Chemical Bank of New York as its prime rate plus 1%, which shall be
set and revised at intervals of six months.  All Subordinated Notes are due
2003; however, principal cannot be paid until the Senior Notes have been paid in
full, unless certain conditions are met.

RESULTS OF OPERATIONS

CAPITAL RESOURCES, CAPITAL SPENDING AND LIQUIDITY

The Mohegan Sun commenced operations on October 12, 1996.  During the period

$76,792,000. On November 15, 1996, Mohegan Sun made an interest payment of
$11,813,000 to the holders of the Senior Notes.  This interest payment consisted

Secured Notes due 2002 (the "Senior Notes") with fixed interest payable at a
rate of 13.5% per annum and cash flow participation interest equal to 5.0% of
the Authority's cash flow up to a limit, during any two consecutive semi-annual
periods ending on September 30, of $250 million of the Authority's cash flow. 
Fixed interest is payable semi-annually on May 15 and November 15.  The Senior
Notes are redeemable after November 15, 1999, at the option of the Authority, at
prices set forth in the Senior Notes.  Upon the occurrence of certain events (as
specified in the Indenture for the Senior Notes), each holder of Senior Notes
can require the Authority to repurchase the Notes at prices specified in the
Senior Notes.  Beginning with the current fiscal year, the Authority will be
required, under certain circumstances, to offer to purchase, at set prices,
certain amounts of Senior Notes then outstanding.  The Indenture governing the
Senior Notes contains certain convenants restricting the Authority's ability to,
among other things, make certain cash payments, incur liens or additional
indebtedness, sell assets, lease property, enter into transactions with
affiliates or effect any merger, consolidation or any transfer or sale of
substantially all of its assets.  The Authority believes it currently is in
compliance with all of the convenants and restrictions contained in the
Indenture.

The Authority obtained $90.0 million of subordinated financing from Sun
International and Waterford Gaming LLC in the form of notes (the "Subordinated
Notes").  On September 29, 1995, the Authority issued $40.0 million of
Subordinated Notes to Sun International.  Subsequent to issuance, Sun
International resold fifty percent of such Subordinated Notes, in a principal
amount equal to $20.0 million, to Waterford Gaming LLC.  Such Subordinated Notes
bear interest at 15.0% per year, payable semi-annually.  Interest on the
Subordinated Notes is being deferred and will not be paid until at least half of
the Senior Notes have been retired (or offered to be retired, pursuant to the
terms of the Indenture governing the Senior Notes) and certain other conditions

have been fulfilled.  The Authority also issued $50.0 million in Subordinated 
Notes to Sun International evidencing draws made by the Authority under the 
$50.0 million secured completion guarantee provided by Sun International (the 
"Secured Completion Guarantee") for completion of construction of the 
facility.  Each Subordinated Note issued under the Secured Completion 
Guarantee bears interest at the rate per annum then most recently announced 
by Chemical Bank of New York as its prime rate plus 1%, which is set and 
revised at intervals of six months. All Subordinated Notes are due 2003; 
however, principal cannot be paid until the Senior Notes have been paid in 
full, unless certain conditions are met.

The Authority's capital expenditures associated with the development of the
facility totaled $67,729,000 for the period from October 12, 1996, through June
30, 1997.  Including land and capitalized interest, the Mohegan Sun is expected
to cost approximately $305 million.  As of June 30, 1997, the Authority had
incurred expenditures of approximately $301.2 million with the development of
the facility.  The Authority may not obligate itself to pay development costs in
excess of $325 million without the further consent of the National Indian Gaming
Commission (the "NIGC").  In the event final development costs exceed $325
million, the Authority would require additional consent of the NIGC, and there
can be no assurances such consent would be given.  Based upon its review of the
budget and the open cost items, the Authority believes that the total cost of
developing, constructing, equipping and opening the Mohegan Sun will not exceed
the sum of the proceeds from the sale of the Senior Notes and the Subordinated
Notes, amounts advanced under the Secured Completion Guarantee, the Equipment
Financing and the Working Capital Financing and cash flow from operations. 
However, there is no assurance that such costs will not exceed budgeted amounts.

Of the Authority's total capital expenditures, those for post-opening
enhancement projects at the facility totaled $7,382,000 for the period from
October 12, 1996, through June 30, 1997.  Capital spending will increase over
the last quarter of the fiscal year.  The additional expenditures will represent
capital projects at the facility, that in the Authority's opinion, will further
enhance the guest's experience at the facility.  The Authority believes that
borrowings under its existing financing agreements and cash flow from operations
will be sufficient to fund its currently planned capital expenditures.

The Authority had a $12.5 million line of credit which expires on September 24,
1997.  Borrowings under this line incur interest at various rates.  As of
June 30, 1997, there is no outstanding working capital under the Fleet 
National Bank line of credit.  The Authority also has a $650,000 line of 
credit which expires on July 31, 1997.  As of June 30, 1997, approximately 
$650,000 was outstanding under this line at an interest rate of 7.75%.  The
funds were used for the initial working capital needs in conjunction with the 
opening of the facility.

RESULTS OF OPERATIONS

CAPITAL RESOURCES, CAPITAL SPENDING AND LIQUIDITY continued 

The Authority entered into equipment financing arrangements with several finance
companies, under varying terms.  As of June 30, 1997, the Authority had
outstanding borrowings under these arrangements of $20.0 million, at an interest
rate of 2% over prime; $4.4 million, at an interest rate of 9.17%; $3.4 million,
at an interest rate of 8.95%; $4.6 million at an interest rate of 12.0%,
$408,000 at an interest rate of 2% over prime and $3.0 million at an interest
rate of 9.3%.  All of such amounts are being repaid by the Authority over a
period from 36 to 48 months.

The Authority believes that existing cash balances and operating cash flow will
provide the Authority with sufficient resources to meet its existing debt
obligations and capital expenditure requirements.  However, the ability of the
Authority to meet its debt service requirements will be entirely dependent upon
future successful performance of the Mohegan Sun, which is subject to financial,
economic, political, competitive, and other factors, many of which are beyond
the Authority's control.
