                               PROSPECTUS SUMMARY
 
   This summary highlights selected information contained elsewhere in this
Prospectus. Because it is a summary, it does not contain all of the information
that is important to you. This summary is qualified in its entirety by the more
detailed information and by the Authority's Consolidated Financial Statements,
the notes thereto and the other financial data that are contained elsewhere in
this Prospectus. You should carefully read this entire Prospectus and the
Letter of Transmittal in their entirety, particularly the section entitled
"Risk Factors" and the financial statements and the related notes to those
statements. References in this Prospectus to the "Authority" are to the Mohegan
Tribal Gaming Authority. The term the "Tribe" refers to the Mohegan Tribe of
Indians of Connecticut. The terms "we" and "us" refer to the Tribe and the
Authority, collectively.
 
The Tribe and the Authority
 
   The Mohegan Tribe of Indians of Connecticut is a federally recognized Indian
tribe with a 390-acre reservation located in southeastern Connecticut. Under
the Indian Gaming Regulatory Act of 1988, federally recognized Indian tribes
are permitted to conduct full-scale casino gaming operations on tribal land,
subject to, among other things, the negotiation of a compact with the affected
state. The Tribe and the State of Connecticut have entered into such a compact
that has been approved by the U.S. Secretary of the Interior. The Tribe's
gaming operation is one of only two legally authorized gaming operations
offering traditional slot machines and table games in the Northeastern United
States outside of Atlantic City, New Jersey. The Tribe has established an
instrumentality, the Mohegan Tribal Gaming Authority, with the exclusive power
to conduct and regulate gaming activities for the Tribe. The Authority is
governed by a Management Board, which consists of the nine members of the
Mohegan Tribal Council.
 
Mohegan Sun
 
   In October 1996, the Authority opened a gaming and entertainment complex
known as Mohegan Sun at a total cost of approximately $303 million. Mohegan Sun
is located in Uncasville, Connecticut, approximately 125 miles from New York
City and approximately 100 miles from Boston, Massachusetts. Mohegan Sun is
situated on a 240-acre site on the Tribe's reservation overlooking the Thames
River with direct access from Routes I-395 and 2A via a four-lane access road
constructed by the Authority. As of December 31, 1998, Mohegan Sun had
approximately 176,500 square feet of gaming space. Mohegan Sun currently offers
 
  .  3,025 slot machines, 150 table games (including blackjack, roulette,
     craps, baccarat, caribbean stud poker and let it ride) and 42 poker
     tables;
 
  .  food and beverage amenities, including three gourmet restaurants, a 680-
     seat buffet, a New York style delicatessen, a 24-hour coffee shop, a 10-
     station food court and multiple service bars for a total of 1,888
     restaurant seats;
 
  .  a high stakes bingo hall with seating for up to 1,400 guests, which is
     also used as an events center that can accommodate up to 1,800 guests;
 
  .  an approximately 10,000 square foot lounge featuring live entertainment
     seven days a week;
 
  .  an approximately 9,000 square foot simulcasting race book facility;
 
  .  parking spaces for 7,500 guests and for 1,700 employees;
 
  .  a children's arcade area and a child care facility operated by New
     Horizons Kids Quest, Inc.; and
 
  .  an approximately 4,000 square foot gas station facility.
 
   Mohegan Sun, which frequently operates at capacity on weekends, does not
currently offer any hotel accommodations or a large-scale dedicated
entertainment venue. Additionally, it offers only limited retail outlets. We
believe that there are significant opportunities to increase revenues and
profits by expanding the gaming space and adding hotel, entertainment and other
amenities.
 
                                       1
<PAGE>
 
 
   For its first fiscal year of operations ended September 30, 1997, Mohegan
Sun welcomed approximately 6.5 million guests and recorded gross revenues of
$512.1 million. During its second fiscal year ended September 30, 1998, Mohegan
Sun had approximately 7.5 million guests, an increase of 15.4% over 1997, and
its gross revenues were $641.4 million, an increase of 25.2% over the prior
year. The Authority's EBITDAM (earnings before extraordinary items, interest,
income taxes, depreciation, amortization and management fees) for the 12 months
ended September 30, 1997 and 1998 were $135.4 million and $200.3 million,
respectively. The Authority's EBITDAM for the quarters ended December 31, 1997
and 1998 were $35.1 million and $51.8 million, respectively.
 
Strategy
 
   Our overall strategy is to profit from expanding demand in the Northeast
gaming market. Our initial success has resulted primarily from guests living
within 100 miles of Mohegan Sun. Based upon Mohegan Sun's results and
experience to date, we believe the Northeast gaming market is strong and that
there is significant demand for additional amenities. We expect to develop
Mohegan Sun into a full-scale entertainment and destination resort and believe
that this will increase the number of guests and lengthen their stays at
Mohegan Sun. Specifically, we plan to expand Mohegan Sun's facilities using the
proceeds from the Outstanding Notes, along with money we borrow pursuant to a
bank credit facility, as well as internally generated cash flow. The expansion
will include additional casino space, a hotel, a large convention facility,
entertainment facilities and additional retail establishments. We will build
the expansion with an effort to minimize disruption to the existing facility
while Mohegan Sun continues to operate. In preparation for the expansion and to
capture existing demand, we have recently widened our marketing efforts to
include the entire New York City metropolitan area. We believe that by
providing Mohegan Sun with additional capacity and the ability to capture a
share of the overnight market in connection with our marketing efforts, we will
extend Mohegan Sun's market penetration. We believe that the expansion will
create a long-term competitive advantage for Mohegan Sun in the East Coast
gaming market. See "Business--Competition."
 
The Mohegan Sun Expansion
 
   To capitalize on the strong market fundamentals in the region and Mohegan
Sun's popularity, we are expanding the casino significantly and adding a hotel,
convention facilities, entertainment facilities and additional retail
establishments. Key elements of the expansion include
 
  .  approximately 100,000 square feet of additional gaming space;
 
  .  a hotel with approximately 1,500 rooms;
 
  .  approximately 100,000 square feet of convention space;
 
  .  an entertainment events center with seating for up to 10,000;
 
  .  nine new restaurants and lounges;
 
  .  approximately 300,000 additional square feet of retail space; and
 
  .  approximately 6,000 additional guest parking spaces.
 
   The Authority commenced construction on the expansion in March, 1999 and
intends to complete the expansion by the fall of 2001. The cost of developing,
constructing, equipping and opening the expansion is expected to be
approximately $750 million (excluding capitalized interest). The Tribe has
issued a formal resolution capping the scope of the expansion budget at $800
million (excluding capitalized interest). In addition, the Tribe has set up a
$40 million construction reserve account that, in some circumstances, will be
used to pay for costs in excess of the expansion budget.
 
 
                                       2
<PAGE>
 
   The Tribe has chosen a project developer, an architect, a cost and
scheduling consultant, a site master planning firm and a retail consultant for
the expansion. The expansion development team currently includes
 
  .  Project Developer--Trading Cove Associates, a joint venture between an
     affiliate of Sun International Hotels Limited and Waterford Gaming
     L.L.C., to oversee the planning, design, construction, furnishing and
     opening of the expansion;
 
  .  Project Architect--Kohn Pedersen Fox Associates PC, an internationally
     recognized architectural firm, to coordinate the design of the expansion
     facilities;
 
  .  Cost and Scheduling Consultant--Hanscomb Limited, an international
     project cost and scheduling consulting firm, to oversee cost planning
     and control and provide other planning and scheduling services;
 
  .  Site Master Planner--EDAW, Inc., a land planning and architectural firm,
     to master plan the expansion site in a manner that minimizes disruption
     to the existing facilities during construction; and
 
  .  Retail Consultant--Gordon Brant LV, LLC, a retail consulting and
     development firm with experience in gaming industry projects, to assist
     with the overall concept and design of the retail facilities of the
     expansion.
 
   We believe the market favors expansion now for several reasons, including:
(1) unsatisfied current demand for gaming space at the existing facility; (2) a
growing gaming market in the Northeast region; (3) length of stay data
indicating the need for a hotel and other amenities; and (4) the need to remain
competitive with the Foxwoods Resort Casino, a neighboring gaming resort. The
expansion is intended to attract a greater number of guests to the facility,
particularly during mid-week periods, and to increase the amount of time and
money guests spend at Mohegan Sun.
 
Market
 
   Mohegan Sun and the Foxwoods Resort Casino are the only two legally
authorized gaming operations offering both traditional slot machines and table
games in the Northeastern United States outside of Atlantic City, New Jersey,
which is approximately 260 miles from Mohegan Sun. Foxwoods is located
approximately 10 miles east of Mohegan Sun and is owned and operated by the
Mashantucket Pequot Tribe. Foxwoods is currently the largest gaming facility in
the United States in terms of the number of total gaming positions. Based on
the size and success of Foxwoods and the rapid growth of Mohegan Sun, we
believe that the gaming market in the Northeastern United States remains
underserved. See "Business--Competition."
 
   Mohegan Sun frequently operates at capacity on weekends. The addition of new
gaming space will accommodate more of this weekend demand. The Authority
estimates that the current average length of time that guests spend at Mohegan
Sun is approximately 110 minutes. We believe that the addition of a large hotel
as well as convention and entertainment amenities will increase the average
length of time guests spend at Mohegan Sun.
 
   In the past, the Authority has marketed primarily to guests living within
100 miles of Mohegan Sun. This excludes most of the New York City metropolitan
area. The Authority has recently begun a substantial marketing effort to tap a
wider market, including the New York City metropolitan area. As a result of
this marketing effort, the number of guests from New York State has grown over
50% from the last fiscal year as measured by Mohegan Sun's guest database. The
Authority believes the majority of this increase can be attributed to guests
residing within the New York City metropolitan area and believes the New York
City market shows significant potential for additional growth. The Authority
also believes the expansion, particularly a large hotel, should draw many
additional customers from this and other more distant markets. See "Business--
Marketing Strategy."

Assumption of Self-Management
 
   The Authority engaged Trading Cove Associates in 1995 to operate, manage and
market Mohegan Sun under a seven-year management agreement. Management fees
paid to Trading Cove Associates under this agreement are based on profitability
thresholds of Mohegan Sun. In anticipation of the expansion of Mohegan Sun, the
Authority and Trading Cove Associates have agreed to terminate this management
arrangement. Under the Relinquishment Agreement, the Authority will formally
assume, and Trading Cove Associates will relinquish, the management, operation
and maintenance of Mohegan Sun on January 1, 2000. The Relinquishment Agreement
provides that the Authority will pay Trading Cove Associates 5% of gross
revenues from Mohegan Sun (as determined under the terms of the Relinquishment
Agreement) beginning January 1, 2000 and ending December 31, 2014. As a result
of this new agreement, the Authority was required to recognize the estimated
present value of this payment obligation as a liability in the fourth fiscal
quarter of 1998. This liability was recorded as a non-cash extraordinary
charge. See "Other Material Agreements--Existing Management Agreement with
Trading Cove Associates" and "--Relinquishment Agreement with Trading Cove
Associates."
 
   Trading Cove Associates has agreed to work closely with the Authority to
facilitate a smooth and effective management transition. The Authority
anticipates entering into long term employment contracts with the senior
managers of Mohegan Sun, three of whom collectively have 45 years of experience
in the gaming and hotel industry. The Authority has also entered into a
development services agreement with Trading Cove Associates to oversee the
planning, design, construction, furnishing and opening of the expansion of
Mohegan Sun. See "Other Material Agreements--Expansion Development Services
Agreement with Trading Cove Associates."

                              See "The Exchange Offers--Exchange Agents."

Resales of Exchange Notes...  The Authority believes that you will be able to
                              offer for resale, resell or otherwise transfer
                              Exchange Notes issued in the Exchange Offers
                              without compliance with the registration and
                              prospectus delivery provisions of the Securities
                              Act, provided that
 
                              .  you are acquiring the Exchange Notes in the
                                 ordinary course of your business;
 
                              .  you are not participating, and have no
                                 arrangement or understanding with any person
                                 to participate, in the distribution of the
                                 Exchange Notes; and
 
                              .  you are not an affiliate of the Mohegan Tribal
                                 Gaming Authority.
 
                              The Authority's belief is based on
                              interpretations by the staff of the SEC, as shown
                              in no-action letters issued to third parties
                              unrelated to the Authority. The staff of the SEC
                              has not considered the Exchange Offers in the
                              context of a no-action letter, and, the Authority
                              cannot assure you that the staff of the SEC would
                              make a similar determination with respect to
                              these Exchange Offers.

                              If the Authority's belief is not accurate and you
                              transfer an Exchange Note without delivering a
                              prospectus meeting the requirements of the
                              Securities Act or without an exemption from such
                              requirements, you may incur liability under the
                              Securities Act. The Authority does not and will
                              not assume, or indemnify you against, such
                              liability.
 
                              Each broker-dealer that receives Exchange Notes
                              for its own account in exchange for Outstanding
                              Notes which were acquired by such broker-dealer
                              as a result of market-making or other trading
                              activities must acknowledge that it will deliver
                              a prospectus meeting the requirements of the

                              such Exchange Notes. A broker-dealer may use this
                              Prospectus for an offer to sell, resale or other
                              transfer of Exchange Notes. See "Plan of

                   SUMMARY OF THE TERMS OF THE EXCHANGE NOTES
 
   The Exchange Offers relate to the exchange of (1) up to $200,000,000
principal amount of Senior Exchange Notes for up to an equal principal amount
of Outstanding Senior Notes and (2) up to $300,000,000 principal amount of
Senior Subordinated Exchange Notes for up to an equal principal amount of
Outstanding Senior Subordinated Notes. The form and terms of the Exchange Notes
are substantially identical to the form and terms of the Outstanding Notes,
except the Exchange Notes will be registered under the Securities Act.
Therefore, the Exchange Notes will not bear legends restricting their transfer
and will not be entitled to registration under the Securities Act. The Exchange
Notes will evidence the same debt as the Outstanding Notes (which they
replace). The Outstanding Senior Notes and the Senior Exchange Notes are
governed by the same indenture, the Senior Notes Indenture. The Outstanding
Senior Subordinated Notes and the Senior Subordinated Exchange Notes are
governed by the same indenture, the Senior Subordinated Notes Indenture.

- --------
(1) The Authority commenced operations at Mohegan Sun on October 12, 1996.
(2) The Authority, in conformance with FASB 5, has recorded a non-cash expense
    and liability for the estimated present value of the Authority's future
    Relinquishment Agreement payment obligations. These payments are based on
    the amount of gross revenue generated by the Authority. As of September 30,
    1998, the present value of this liability was estimated at $549.1 million,
    of which $419.1 million was reflected as an extraordinary item in the
    statements of income (loss), and $130.0 million was capitalized
 
                                       13
<PAGE>
 
    on the balance sheet as trademarks and other intellectual property acquired
    as part of the Relinquishment Agreement. Recording this liability has
    created negative capital as of September 30, 1998. This liability will be
    reassessed periodically and may require additional non-cash adjustments to
    be recorded in the statement of income (loss). The estimated liability has
    not changed as of December 31, 1998. See the Authority's financial
    statements and the accompanying notes and "Other Material Agreements--
    Relinquishment Agreement with Trading Cove Associates."
(3) The ratio of earnings to fixed charges is determined by dividing (a)
    earnings before extraordinary items and fixed charges by (b) fixed charges.
    Fixed charges consist of total interest expense, including cash flow
    participation interest relating to the 13 1/2% Senior Secured Notes.
(4) Earnings before extraordinary items, interest, income taxes, depreciation
    and amortization. EBITDA is presented because we believe it is frequently
    used by securities analysts, investors and other interested parties in the
    gaming industry. However, EBITDA should only be read in conjunction with
    all of the Authority's financial data summarized above and its financial
    statements, including the notes, prepared in conformance with generally
    accepted accounting principles or GAAP appearing elsewhere herein. EBITDA
    should not be construed as an alternative either to (a) income from
    operations (as determined according to GAAP) as an indicator of the
    Authority's operating performance or (b) cash flows from operating
    activities (as determined according to GAAP) as a measure of liquidity. In
    addition, because the Authority is an instrumentality of a sovereign Indian
    nation, it is not subject to federal or state income tax.
(5) Earnings before extraordinary items, interest, income taxes, depreciation,
    amortization and management fees. Management fees are paid by the Authority
    to Trading Cove Associates under the terms of its management agreement
    which terminates on January 1, 2000. Until such termination and because
    management fees are subordinate to debt service, the Authority believes
    EBITDAM is a supplemental financial measurement useful in the evaluation of
    its gaming business.
(6) As adjusted amounts reflect (a) the sale of the Outstanding Notes and the
    application of the related net proceeds, including to redeem $175.0 million
    in aggregate principal amount of senior secured notes and to establish a
    defeasance trust account for junior subordinated notes of the Authority;
    (b) the release of restricted cash balances to the Authority in the amount
    of $81.3 million; and (c) the closing of the Bank Credit Facility with no
    loan amounts drawn.
(7) The Authority created a defeasance trust account as of March 3, 1999 and
    deposited into such defeasance trust cash or government securities
    estimated to be sufficient to redeem its junior subordinated notes. The
    Authority has outstanding $40.0 million of junior subordinated notes
    bearing interest at 15% per annum and $50.0 million of junior subordinated
    notes bearing interest at prime rate plus 1% per annum. These notes do not
    pay cash interest. The Authority will redeem these notes on January 1,
    2000, the first permitted redemption date, at a price of 100% of the
    principal amount plus accrued and unpaid interest less $500,000.
(8) Actual and as adjusted amounts include $90.0 million of principal and $35.2
    million of accrued and unpaid interest related to junior subordinated notes
    which were defeased as of March 3, 1999 and will be redeemed on January 1,
    2000.
(9) As adjusted amounts reflect a tender premium of $37.9 million for
    redemption of senior secured notes.

                                  RISK FACTORS
 
   You should carefully consider the information below, as well as all other
information provided to you in this Prospectus before tendering your
Outstanding Notes in the Exchange Offers.
 
High Degree of Leverage; Restrictive Loan Covenants
 
   The Authority's substantial indebtedness could adversely affect its
financial health and prevent it from fulfilling its obligations under the
Exchange Notes.
 
   The Authority currently has and will continue to have a significant amount
of indebtedness. Total debt and capital lease obligations (including accrued
and unpaid interest on junior subordinated notes) as of December 31, 1998 were
$328.0 million. As of the same date and as adjusted to reflect (1) the sale of
the Outstanding Notes and the application of the related net proceeds,
including the redemption of $175.0 million in aggregate principal amount of
senior secured notes and the establishment of a defeasance trust account for
the Authority's junior subordinated notes; (2) the release of restricted cash
balances to the Authority in the amount of $81.3 million; and (3) the closing
of the Bank Credit Facility with no loan amounts drawn, total debt and capital
lease obligations would have been $653.0 million. In addition, the Authority
has borrowing capacity under the Bank Credit Facility of up to $500.0 million.
If the Authority had fully drawn all possible amounts available under the Bank
Credit Facility, total debt and capital lease obligations would be
approximately $1.2 billion.
 
   The Authority's substantial indebtedness could have important consequences
to you. For example, it could
 
  .  make it more difficult for the Authority to satisfy its obligations with
     respect to the Exchange Notes;
 
  .  increase the Authority's vulnerability to adverse economic and industry
     conditions;
 
  .  limit the Authority's ability to fund future working capital, capital
     expenditures and other general corporate requirements;
 
  .  require the Authority to dedicate a substantial portion of its cash flow
     from operations to payments on the Authority's indebtedness, thereby
     reducing the availability of the Authority's cash flow to fund working
     capital, capital expenditures and other general corporate purposes;
 
  .  limit the Authority's flexibility in planning for, or reacting to,
     changes in its business and the industry in which the Authority
     operates;
 
  .  place the Authority at a disadvantage compared to its competitors that
     have less debt; and
 
  .  limit, along with the financial and other restrictive covenants in the
     Authority's other indebtedness, among other things, the Authority's
     ability to borrow additional funds.
 
   Failure by the Authority to comply with covenants in its debt instruments
could result in an event of default which, if not cured or waived, could have a
material adverse effect on the Authority. See "Description of Exchange Notes--
Description of the Senior Exchange Notes--Repurchase at the Option of Holders--
Change of Control," "--Description of the Senior Subordinated Exchange Notes--
Repurchase at the Option of Holders--Change of Control" and "Description of
Other Indebtedness--Bank Credit Facility."
 
   The Bank Credit Facility includes covenants that, among other things,
restrict the Authority's ability to do the following:
 
  .  pay dividends and make other restricted payments;
 
  .  incur additional indebtedness;
 
                                       15
<PAGE>
 
  .  grant liens, other than liens created under the new Bank Credit Facility
     and certain other permitted liens;
 
  .  sell material assets; and
 
  .  make capital expenditures (subject to amounts for the casino expansion).
 
   The Bank Credit Facility will also require the Authority to maintain
specified financial ratios, including interest coverage and leverage ratios and
not to exceed specified fixed ratios of senior indebtedness to EBITDA. There
can be no assurance that these requirements will be met in the future. If they
are not, the holders of the indebtedness under the Bank Credit Facility would
be entitled to declare such indebtedness immediately due and payable. See
"Description of Other Indebtedness--Bank Credit Facility."
 
Unsecured Ranking and Subordination to Existing Indebtedness
 
   The Authority's obligations under the Indentures are not secured. Your right
to receive payments on the Senior Exchange Notes will effectively be
subordinated to the Authority's Bank Credit Facility and other secured
indebtedness. Your right to receive payments on the Senior Subordinated
Exchange Notes will be junior to the Authority's existing and future senior
indebtedness, including the Bank Credit Facility and the Senior Exchange Notes.
 
 Senior Exchange Notes
 
   The Senior Exchange Notes are general unsecured obligations of the Authority
and rank pari passu in right of payment with all current and future unsecured
senior indebtedness of the Authority. However, borrowings under the Bank Credit
Facility and other equipment financing arrangements are secured by first
priority liens on substantially all of the assets of the Authority. As a
result, upon any distribution to creditors in a bankruptcy, liquidation or
reorganization or similar proceeding relating to the Authority or the Tribe,
the holders of secured debt may be paid in full in cash before any payment may
be made with respect to the Senior Exchange Notes. Assuming the Authority had
fully drawn all possible amounts under the Bank Credit Facility on December 31,
1998, the Senior Exchange Notes would have been subordinated to approximately
$500 million of senior secured debt. In addition, under the Relinquishment
Agreement with Trading Cove Associates, beginning on January 1, 2000 and ending
on December 31, 2014, the Authority has agreed to pay Trading Cove Associates
5% of Mohegan Sun's gross revenues (calculated under the terms of the
Relinquishment Agreement) to compensate Trading Cove Associates for terminating
its management rights. 50% of this payment ranks equal in right of payment to
the Senior Exchange Notes and the remaining 50% of this payment ranks junior in
right of payment to the Senior Exchange Notes.
 
 Senior Subordinated Exchange Notes
 
   In the event of a bankruptcy, liquidation or reorganization or similar
proceeding relating to the Authority or the Tribe, holders of the Senior
Subordinated Exchange Notes will participate with trade creditors and all other
holders of subordinated indebtedness in the assets remaining after the
Authority or the Tribe has paid all of the senior debt, including the Senior
Exchange Notes. However, because the Senior Subordinated Notes Indenture
requires that amounts otherwise payable to the holders of the Senior
Subordinated Exchange Notes in a bankruptcy or similar proceeding be paid to
holders of designated senior debt instead, holders of the Senior Subordinated
Exchange Notes may receive less, ratably, than holders of trade payables in any
such proceedings. In any of these cases, the Authority or the Tribe may not
have sufficient funds to pay all creditors and holders of the Senior
Subordinated Exchange Notes may receive less, ratably, than the holders of
senior debt.
 
   Assuming the Authority had fully drawn all possible amounts under the Bank
Credit Facility, the Senior Subordinated Exchange Notes would have been
subordinated to approximately $700 million of senior debt. The Authority will
be permitted to borrow substantial additional indebtedness, including senior
debt, in the future under the terms of the Indentures. In the event of a
liquidation, bankruptcy or a similar proceeding, the Senior
 
                                       16
<PAGE>
 
Subordinated Exchange Notes are subordinated to 50% of the Authority's payment
obligations under the Relinquishment Agreement that are then due and owing, but
are effectively not subordinated to such payment obligations that are not yet
due under the Relinquishment Agreement since the payment obligations under the
Relinquishment Agreement cannot be accelerated by their terms and have no
blockage rights as Designated Senior Debt. In addition, the Senior Subordinated
Exchange Notes rank equally to the remaining 50% of the Authority's payment
obligations under the Relinquishment Agreement that are then due and owing, but
are effectively senior to such payment obligations that are not yet due under
the Relinquishment Agreement since payment obligations under the Relinquishment
Agreement cannot be accelerated by their terms.
 
Difficulties in Enforcing Obligations Against the Authority
 
   Your ability to enforce your rights against the Authority is limited by the
Tribe's sovereign immunity.
 
   Although the Tribe and the Authority have sovereign immunity and may not be
sued without their consent, both the Tribe and the Authority have granted a
limited waiver of sovereign immunity and consent to suit in connection with the
Exchange Notes, the Indentures and the other documents related to the Exchange
Notes. Such waiver includes suits against the Authority to enforce its
obligation to repay the Exchange Notes. If such waiver of sovereign immunity is
held to be ineffective, the Trustees (as defined) and the holders of the
Exchange Notes could be precluded from judicially enforcing their rights and
remedies. Generally, waivers of sovereign immunity have been held to be
enforceable against Indian tribes. Neither the Authority nor the Tribe has
waived sovereign immunity from private civil suits, including violations of the
federal securities laws. For this reason, an investor may not have any remedy
against the Authority or the Tribe for violations of federal securities laws.
 
   The Tribe's Constitution has established a special court, the Gaming
Disputes Court, to rule on disputes with respect to Mohegan Sun, including any
disputes relating to the Notes and the Indentures. The Gaming Disputes Court
must consist of at least four judges, none of whom may be members of the Tribal
Council or their families and each of whom must be either a retired federal
judge or a Connecticut attorney trial referee (who are attorneys appointed by
the Connecticut Supreme Court). Appeals of the decisions of the Trial Division
are heard by the Appellate Branch of the Gaming Disputes Court. Matters as to
which applicable federal or state courts have jurisdiction may be brought in
such courts. However, the federal courts may not have jurisdiction over
disputes not arising under federal law, and the state courts may not have
jurisdiction over any disputes arising on the Mohegan reservation. Moreover the
federal and state courts, under the doctrines of comity and exhaustion of
tribal remedies, may be required (1) to defer to the jurisdiction of the Gaming
Disputes Court, or (2) to require that any plaintiff exhaust its remedies in
the Gaming Disputes Court before bringing any action in the federal or state
court. Thus, there may be no federal or state court forum with respect to a
dispute relating to the Exchange Notes or the Indentures. In addition, the
Authority may not be subject to the federal bankruptcy laws. Thus, no assurance
can be given that, if an event of default occurs under the Indentures, any
forum will be available to the holders of the Exchange Notes other than the
Gaming Disputes Court. In such a court, there are few guiding precedents for
the interpretation of Tribal law. Any execution of a judgment of the Gaming
Disputes Court will require the cooperation of the Tribe's officials in the
exercise of their police powers. Thus, to the extent that a judgment of the
Gaming Disputes Court must be executed on Tribal lands, the practical
realization of any benefit of such a judgment will be dependent upon the
willingness and ability of Tribal officials to carry out such judgment. In
addition, the land under the casino facility is owned by the United States in
trust for the Tribe, and creditors of the Authority or the Tribe may not force
or obtain title to the land. See "Mohegan Tribe of Indians of Connecticut--
Gaming Disputes Court."
 
   The Tribe is permitted to amend the provisions of its Constitution that
establish the Authority and the Gaming Disputes Court with the approval of two-
thirds of the members of the Tribal Council and a ratifying vote of a two-
thirds majority of all votes cast, with at least 40% of the registered voters
of the Tribe voting. However, before the enactment of any such amendment by the
Tribal Council, any non-tribal party will have the opportunity to seek a ruling
from the Appellate Branch of the Gaming Disputes Court that the proposed
amendment would constitute an impermissible impairment of contract. Further,
the Tribal Constitution prohibits
 
                                       17
<PAGE>
 
the Tribe from enacting any law that would impair the obligations of contracts
entered into in furtherance of the development, construction, operation and
promotion of gaming on Tribal lands. Amendments to this provision of the
Tribe's Constitution require the affirmative vote of 75% of all registered
voters of the Tribe. The Tribe has approximately 750 registered voters.
Amendment to any of such provisions of the Tribe's Constitution could adversely
affect the ability of the holders of the Exchange Notes to enforce the
obligations of the Authority on the Exchange Notes.
 
Exclusive Reliance on Gaming Revenue for Debt Service Payments
 
   Mohegan Sun's failure to generate sufficient cash flow could prevent the
Authority from fulfilling its obligations under the Exchange Notes.
 
   The Authority relies on revenues from the gaming operations of Mohegan Sun
to meet its debt service requirements. Such operations are subject to many
financial, economic, political, competitive and regulatory factors beyond the
Authority's control. If Mohegan Sun is unable to generate sufficient cash flow,
the Authority could be required to reduce or delay planned capital
expenditures, dispose of certain assets and/or seek to restructure some or all
of its debt. There can be no assurance that any of these alternatives could be
effected, if at all, on satisfactory terms.
 
Risks of Expansion
 
   Failure to complete Mohegan Sun's expansion on budget and on time could
adversely affect the financial health of the Authority.
 
   Construction projects such as the expansion of Mohegan Sun are inherently
subject to significant development and construction risks. These include the
following:
 
  .  labor disputes;
 
  .  shortages of material and skilled labor;
 
  .  weather interference;
 
  .  engineering problems;
 
  .  environmental problems (including asbestos, lead and hazardous waste
     removal);
 
  .  fire, flood and other natural disasters; and
 
  .  geological, construction, demolition, excavation, regulatory and/or
     equipment problems.
 
   All of these risks could cause unanticipated cost increases. Although we
have chosen a developer and have preliminary plans, the final plans for the
expansion are still under development. The actual cost and scope of the project
will be dependent upon the final plans. The Tribe expects the expansion to cost
approximately $750 million (excluding capitalized interest) and has adopted a
formal resolution capping the expansion budget at $800 million to account for
any unforeseen design changes or enhancements. In addition, the Tribe has
established a $40 million construction reserve account that, in some
circumstances, will be used to pay for costs in excess of the expansion budget.
 
   The anticipated construction costs and completion dates for the expansion
are based on budgets, conceptual design documents and schedule estimates
prepared by Trading Cove Associates for the Authority with the assistance of
certain architects and contractors. The final amount of the project is subject
to modification based upon the occurrence of particular events, such as design
change order delays. Construction in the northeastern United States is also
subject to a number of weather related risks. Long winters and severe or
unexpected rain, storms or other bad weather may delay completion and/or
increase the costs of the construction.
 
 
                                       18
<PAGE>
 
   The expansion is scheduled to be completed in the fall of 2001. There can be
no assurance that the expansion facilities will commence operations on schedule
or that construction costs for the expansion will not exceed budget. Failure to
complete the expansion within the budget or on schedule may have a material
adverse effect on the results of Mohegan Sun's operations and the Authority's
financial condition.
 
   Although construction activities related to the expansion of Mohegan Sun are
planned to minimize disruption, construction noise and debris and the temporary
closing of some facilities may disrupt Mohegan Sun's current operations.
Unexpected construction delays could exacerbate or magnify these disruptions.
There can be no assurance that construction of the expansion will not have a
material adverse effect the Authority's results of operations.
 
Failure to Obtain Funds to Complete Expansion
 
   In the event Mohegan Sun fails to achieve expected results, the Authority
may not have sufficient funds to complete Mohegan Sun's expansion.
 
   The Authority expects that approximately $376.0 million of the Mohegan Sun
expansion will be financed from cash flow from operations through December 31,
2001. There can be no assurances that Mohegan Sun will generate sufficient cash
flow from operations to finance the Mohegan Sun expansion. If Mohegan Sun fails
to generate cash flow as expected, the expansion could be delayed, resulting in
a material adverse effect on the financial condition of the Authority.
 
Competition from Other Gaming Operations
 
   Many competitors have greater resources than the Authority, and other Indian
tribes may receive approval to engage in casino gaming.
 
   The gaming industry is highly competitive. Mohegan Sun currently competes
primarily with the Foxwoods Resort Casino and, to a lesser extent, with casinos
in Atlantic City, New Jersey. Foxwoods is approximately 10 miles from Mohegan
Sun and is the largest gaming facility in the United States in terms of total
gaming positions. In addition, Foxwoods offers a number of amenities that
Mohegan Sun does not have, including hotel accommodations, extensive retail
shopping and more expansive non-gaming entertainment offerings. Foxwoods has
been in operation for nearly seven years and may have greater financial
resources and greater operating experience than the Authority or the Tribe.
 
   Upon the completion of the expansion, the Authority intends to broaden
Mohegan Sun's market beyond day-trip customers to include guests making
overnight stays at the resort. This means that Mohegan Sun will begin to
compete more directly for customers with casinos in Atlantic City, New Jersey
and, to a lesser extent, gaming resorts such as those on the Gulf Coast of
Mississippi and Las Vegas, Nevada. Many of these casinos and other resorts have
greater resources and greater name recognition than Mohegan Sun.
 
   Under current law, outside of Atlantic City, New Jersey, casino gaming in
the northeastern United States may be conducted only by federally recognized
Indian tribes operating under federal Indian gaming law. Currently, the Oneida
Indian Nation operates Turning Stone Casino Resort in Verona, New York,
approximately 270 miles from Mohegan Sun. The St. Regis Mohawk Tribe in
Hogansburg, New York near the Canadian border has entered into a gaming compact
with the state of New York. Although this tribe has yet to develop a gaming
facility, it has initiatives both on its reservation in Hogansburg (for which
it has had a gaming management contract approved by the National Indian Gaming
Commission) and at Monticello Raceway in the Catskills, 90 miles from New York
City (for which it has received Bureau of Indian Affairs Eastern Area Office
approval to take land into trust). Both initiatives still require additional
federal and state level approvals. In addition, at least two other federally
recognized tribes in New England are each seeking to establish gaming
operations. Several other tribes in New England are seeking federal recognition
as Native American peoples with the intent of establishing gaming operations. A
number of states, including Connecticut
 
                                       19
<PAGE>
 
and New York, have also investigated legalizing casino gaming by non-Indians in
one or more locations. The Authority cannot predict whether any of these other
tribes or other efforts to legalize casino gaming will be successful in
establishing gaming operations, and if established, whether such gaming
operations will have a material adverse effect on the Authority's proposed
operations. See "Business--Competition."
 
Need to Obtain Construction Related Licenses and Permits
 
   A failure to obtain necessary licenses and permits could delay the expansion
of Mohegan Sun thereby causing a material adverse effect on operating results.
 
   No assurances can be given that the required licenses, permits or other
approvals for the expansion of Mohegan Sun will be issued. Even if issued, such
licenses, permits or other approvals could have conditions or restrictions that
could adversely affect the completion of the expansion. The failure to obtain
any of these licenses, permits or other approvals in a timely manner may delay,
restrict or prevent the expansion from being completed as contemplated herein.
See "Government Regulation."
 
Reliance on Nearby Markets
 
   A downturn in the local economy could negatively impact the Authority's
financial performance.
 
   Until and for some time after the expansion is completed, Mohegan Sun will
depend heavily on day-trip customers. Any downturn in the regional economy, the
entrance of new competitors or the expansion of existing competitors within
this local market could have a material adverse effect on the Authority's
results of operations. See "--Competition From Other Gaming Operations."
 
Limited Operating History Associated with the Operation
 
   Mohegan Sun is subject to the risks of a new business.
 
   Mohegan Sun did not begin operations until October 12, 1996 and has many of
the same risks inherent in the establishment of a new business enterprise. In
addition, Mohegan Sun's limited operating history makes the prediction of the
Authority's future operating results difficult.
 
Management of Growth; Uncertainty of Future Expanded Operations
 
   The transition to full management responsibility for the Authority coupled
with the risks associated with operating a substantially expanded facility
could have a material adverse effect on Mohegan Sun's future performance.
 
   Mohegan Sun's profitability has been partially dependent upon the efforts
and skills of Trading Cove Associates. Trading Cove Associates will have legal
responsibility for overseeing and managing Mohegan Sun until December 31, 1999.
While the Authority has already assumed many of Mohegan Sun's day-to-day
management functions, on January 1, 2000, it will assume full management,
operation and maintenance responsibility of Mohegan Sun. There can be no
assurance that the Authority will be as successful managing Mohegan Sun as
Trading Cove Associates has been. See "Other Material Agreements."
 
   Mohegan Sun, when expanded, will have significantly larger gaming
facilities, entertainment venues and retail space, as well as new hotel and
convention facilities. There can be no assurance that the Authority will be
successful in integrating the planned casino and resort expansion into Mohegan
Sun's current operations or in managing the expanded resort. The failure to
integrate and manage the new services and amenities successfully could have a
material adverse effect on the Authority's results of operations.
 
                                       20
<PAGE>
 
Dependence on Key Personnel; Significant Change in Tribal Management
 
   The loss of any key management member or any significant change in the
makeup of the Tribal Council could have a material adverse effect on Mohegan
Sun.
 
   Mohegan Sun's success depends in large part on the continued service of key
management personnel, particularly William Velardo, the Authority's Executive
Vice President and General Manager, Mitchell Etess, the Authority's Senior Vice
President of Marketing, and Jeffrey Hartmann, the Authority's Chief Financial
Officer. The loss of the services of one or more of these individuals or other
key personnel could have a material adverse effect on the Authority's business,
operating results and financial condition. See "The Authority."
 
   Additionally, Roland J. Harris serves as Chairman of the Tribal Council of
the Tribe and Chairman of the Management Board of the Authority. The Members of
the Tribal Council, including the Chairman, are elected by the Tribe every five
years. The next election is in October of 2000. The loss of Mr. Harris's
services, as well as a significant change in the composition of the Tribal
Council, could have a material adverse effect on the Authority and the
development of the Mohegan Sun expansion. See "Mohegan Tribe of Indians of
Connecticut."
 
Regulatory Redemption
 
   Your Exchange Notes may be redeemed automatically if your ownership of the
Exchange Notes jeopardizes the Authority's gaming licenses.
 
   The Authority will have the right to redeem the Exchange Notes if any holder
of Exchange Notes jeopardizes the Authority's gaming license by not having
required licenses or qualifications. The redemption price for these Exchange
Notes, without accrued interest, is equal to the lowest of the holder's cost,
the principal amount of such Exchange Notes or the average of the current
market price of such Exchange Notes. See "Description of Exchange Notes--
Description of the Senior Exchange Notes--Optional Redemption" and "Description
of Exchange Notes--Description of the Senior Subordinated Exchange Notes--
Optional Redemption."
 
Highly Regulated Industry
 
   Changes in the law could have a material adverse effect on the Authority's
ability to conduct gaming.
 
   Gaming on the Tribe's reservation is extensively regulated by federal, state
and tribal regulatory bodies, including the National Indian Gaming Commission
and agencies of the State of Connecticut (for example, the Division of Special
Revenue, the State Police and the Department of Liquor Control). As is the case
with any casino, changes in applicable laws and regulations could limit or
materially affect the types of gaming that may be conducted by the Authority
and the revenues realized therefrom.
 
   In August 1996, federal legislation became effective, creating a nine-member
commission to examine and prepare a report within three years on the effects of
gambling, including gambling on riverboats, Indian reservations and at non-
Indian casinos. No prediction can be made as to what, if any, legislation might
arise from such a report if it is completed. Moreover, Congress has regulatory
authority over Indian affairs and can establish and change the terms upon which
Indian tribes may conduct gaming. Currently, the operation of all gaming on
Indian lands is subject to the Indian Gaming Regulatory Act of 1988. For the
past several years, legislation has been introduced in Congress with the intent
of modifying a variety of perceived problems with this act. Virtually all of
the proposals that have been seriously considered would be prospective in
effect and have contained clauses that would grandfather existing Indian gaming
operations such as Mohegan Sun. Bills have also been proposed, however, which
would have the effect of repealing many of the key provisions of the Indian
Gaming Regulatory Act and prohibiting the continued operation of particular
classes of gaming on specified Indian reservations in states where such gaming
is not otherwise allowed on a commercial basis.
 
                                       21
<PAGE>
 
However, none of the substantive proposed amendments to the Indian Gaming
Regulatory Act have proceeded out of committee hearings to a vote by either the
House or the Senate.
 
   While it is possible that retroactive legislation could be adopted forcing
the closure of existing Indian gaming enterprises, given the number of existing
gaming compacts and tribal gaming operations nationwide, we believe that it is
unlikely that Congress would enact such legislation without grandfathering
existing Indian gaming operations. Furthermore, such legislation would
certainly be challenged by us and other Indian gaming operations as an invalid
exercise of Congressional authority. However, if Congress passes prohibitory
legislation that does not include any grandfathering exemption for existing
tribal gaming operations, and if such legislation is sustained in the courts
against tribal challenge, the Authority's ability to meet its obligations to
creditors, including the holders of the Notes, would be doubtful.
 
   Under federal law, gaming on Indian land is dependent on the permissibility
under state law of specified forms of gaming or similar activities. If the
State of Connecticut were to make various forms of gaming illegal or against
public policy, such action may have an adverse effect on the ability of the
Authority to conduct gaming. Connecticut currently permits, among other things,
a state lottery, jai alai fronton betting and off-track betting parlors. If
Connecticut were to make gaming against public policy, it would forfeit the
substantial income ($276.2 million for the 12 months ended December 31, 1998)
derived from the gaming activities at Mohegan Sun and Foxwoods and the
resulting slot contributions to the state. See "Other Material Agreements--
Gaming Compact with the State of Connecticut."
 
Possible Environmental Liabilities
 
   Risks of material environmental liability may remain as a result of
incomplete remediation of known environmental hazards.
 
   The Authority currently incurs and may continue to incur costs to comply
with environmental requirements, such as those relating to discharges to air,
water and land, the handling and disposal of solid and hazardous waste, and the
cleanup of properties affected by hazardous substances. Under such
environmental requirements, a current or previous owner or operator of real
estate may be required to investigate and clean up hazardous or toxic
substances or chemical releases at such property. The owner or operator may
also be held liable to a governmental entity or to third parties for property
damage, personal injury and for investigation and cleanup costs incurred by
such parties in connection with the contamination. These laws typically impose
cleanup responsibility and liability without regard to whether the owner knew
of or caused the presence of the contaminants, and the liability under such
laws has been interpreted to be joint and several unless the harm is divisible
and there is a reasonable basis for allocation of responsibility. The costs of
investigation, remediation or removal of such substances may be substantial,
and the presence of such substances, or the failure to remediate such property
properly, may adversely affect the owner's ability to rent such property or to
borrow using such property as collateral. In addition, the owner or former
owners of a site may be subject to common law claims by third parties based on
damages and costs resulting from environmental contamination emanating from the
site. In addition, environmental requirements address the impacts of
development on wetlands areas. See "Business--The Expansion."
 
   The site on which Mohegan Sun is located was formerly occupied by United
Nuclear Corporation, a naval products manufacturer of, among other things,
nuclear reactor fuel components. United Nuclear Corporation's facility was
officially decommissioned on June 8, 1994 when the Nuclear Regulatory
Commission confirmed that all licensable quantities of special nuclear material
had been removed from the site and that any residual special nuclear material
contamination was remediated according to an approved decommissioning plan.
 
   From 1991 through 1993, United Nuclear Corporation commissioned
environmental audits and soil sampling programs which detected, among other
things, volatile organic chemicals, heavy metals and fuel hydrocarbons in the
soil and groundwater. Extensive remediation of contaminated soils and
additional investigations were completed. In addition, initial construction at
the site involved extensive soil excavation
 
                                       22
<PAGE>
 
and contaminated soils were removed during the excavation. The site currently
meets state remediation requirements.
 
   Under the terms of United Nuclear Corporation's environmental certification
and indemnity agreement with the Department of the Interior (which took the
former United Nuclear Corporation land into trust for the Mohegan Tribe),
United Nuclear Corporation agreed to indemnify the Department for environmental
actions and expenses based on acts or conditions existing or occurring as a
result of United Nuclear Corporation's activities on the property.
Notwithstanding the foregoing, no assurance can be given (1) that the various
environmental reports or any other existing environmental studies revealed all
environmental liabilities, (2) that any prior owners or tenants did not create
any material environmental condition not known to us, (3) that future laws,
ordinances or regulations will not impose any material environmental liability,
or (4) that a material environmental condition does not otherwise exist on the
site.
 
Taxation of Indian Gaming
 
   A change in the Authority's current tax-exempt status could have a material
adverse effect on the Authority's ability to repay its obligation under the
Exchange Notes.
 
   Based on current interpretation of the tax code, neither the Tribe nor the
Authority is a taxable entity for purposes of federal income taxation. There
can be no assurance that Congress will not reverse or modify the exemption for
Indian tribes from federal income taxation.
 
   Efforts have been made in Congress over the past several years to amend the
Internal Revenue Code to provide for taxation of the net income of tribal
business entities. These have included a House bill which would have taxed
gaming income earned by Indian tribes as unrelated business income subject to
corporate tax rates. Although no such legislation has been enacted, some could
be passed in the future. Future proposals or amendments in this area could
materially and adversely affect the market value of the Exchange Notes or the
Authority's ability to pay the principal and interest on the Exchange Notes.
 
Change of Control Events
 
   The Authority may lack sufficient funds to effect a repurchase of the
Exchange Notes upon a change of control.
 
   Upon the occurrence of specified change of control events, the Authority
will be required to offer to repurchase all then outstanding Exchange Notes.
The Authority may not have the ability to raise the funds necessary to finance
the change of control offer required by the Indentures.
 
Year 2000 Date Conversion
 
   Failure by the Authority to address the Year 2000 problem adequately may
have a material adverse effect on results of operations.
 
   The Authority is currently working to verify system readiness for the
processing of date-sensitive information by its computerized information
systems to the end of the century. The "Year 2000" problem impacts computer
programs and hardware timers using two digits (rather than four) to define the
applicable year. Any of the Authority's programs that have time-sensitive
functions may recognize a date using "00" as the year 1900 rather than 2000, or
not at all, which could result in miscalculations or system failures. The
Authority, like many companies, depends on fully operational computer systems
in all areas of its business. As a large facility in a relatively remote
location, Mohegan Sun is heavily dependent on a local infrastructure which may
not be adequate to take on the challenges of the Year 2000 problem. It is
especially dependent on that local infrastructure for critical services such as
incoming utilities and outgoing sewage. Additionally, the Authority is
dependent upon many vendors such as food and beverage suppliers, outside
software suppliers and system integrators to provide uninterrupted service for
the operation to run effectively.
 
                                       23
<PAGE>
 
   With the assistance of an outside consultant, the Authority has implemented
a Year 2000 program to provide an independent analysis of the Authority's Year
2000 preparedness and the adequacy of the Authority's Year 2000 plans. The
program includes inventorying entities, identifying problems, planning
compliance and implementation strategies, attempting to correct the problems
and testing the solutions.
 
   As of March 31, 1999, Mohegan Sun was approximately 75% in conformance with
the GartnerGroup Year 2000 best practices model. The Authority anticipates
completion of the program by June 1999. Although there can be no assurance, it
is anticipated that remediation and verification to become Year 2000 compliant
will not exceed $1.0 million and will not have a material adverse impact on the
Authority's financial position, results of operations, or cash flow. While the
Authority's efforts are designed to be successful, because of the complexity of
the Year 2000 issues and the interdependence of organizations using computer
systems, there can be no assurance that the Authority's efforts, or those of a
third party with whom the Authority interacts, will be satisfactorily completed
in a timely fashion. This could result in a material adverse effect on future
operations. See "Management's Discussion and Analysis of Financial Condition
and Results of Operations."
 
Certain Transfer Restrictions; No Prior Market for Exchange Notes; Failure to
Exchange the Outstanding Notes
 
   Certain transfer restrictions and the failure of a market to develop could
affect the liquidity and price of your Exchange Notes. In the event you do not
exchange your Outstanding Notes, you cannot be assured of a continuation of a
trading market for the Outstanding Notes.
 
   You may generally sell Exchange Notes without complying with the
registration requirements of the Securities Act, unless you are:
 
  .  an "affiliate" of the Company within the meaning of Rule 405 under the
     Securities Act
 
  .  a broker-dealer that acquired Outstanding Notes as a result of market-
     making or other trading activities
 
  .  a broker-dealer that acquired Outstanding Notes directly from us for
     resale pursuant to Rule 144A or another available exemption under the
     Securities Act
 
   "Affiliates" of the Authority may sell Exchange Notes only in compliance
with the provisions of Rule 144 under the Securities Act or another available
exemption. The broker-dealers described above must deliver a prospectus in
connection with any resale of Exchange Notes.
 
   The Exchange Notes constitute a new issue of securities for which no
established trading market exists. If Exchange Notes are traded after their
initial issuance, they may trade at a discount, depending upon the Authority's
financial condition, prevailing interest rates, the market for similar
securities and other factors beyond the Authority's control, including general
economic conditions. The Authority does not intend to apply for a listing or
quotation of the Exchange Notes on any securities exchange. The initial
purchasers of the Outstanding Notes have informed the Authority that they
intend to make a market in the Exchange Notes. However, the initial purchasers
have no obligation to do so, and may discontinue any market-making activities
at any time without notice. The Authority cannot assure you of the development
or liquidity of any trading market for the Exchange Notes following the
Exchange Offers.
 
   The Authority has not registered nor does it intend to register the
Outstanding Notes under the Securities Act. Outstanding Notes that remain
outstanding after consummation of the Exchange Offers will therefore remain
subject to transfer restrictions under applicable securities laws. Unexchanged
Outstanding Notes will continue to bear a legend reflecting these restrictions
on transfer. Furthermore, the Authority has not conditioned the Exchange Offers
on receipt of any minimum or maximum principal amount of Outstanding Notes. As
Outstanding Notes are tendered and accepted in the Exchange Offers, the
principal amount of
 
                                       24
<PAGE>
 
remaining Outstanding Notes will decrease. This decrease will reduce the
liquidity of the trading market for the Outstanding Notes. The Authority cannot
assure you of the liquidity, or even the continuation, of the trading market
for the Outstanding Notes following the Exchange Offers.
 
Risks of Not Complying with Exchange Offer Procedures
 
   In order to receive Exchange Notes, you must follow the Exchange Offer
procedures.
 
   You are responsible for complying with all Exchange Offer procedures. You
will only receive Exchange Notes in exchange for your Outstanding Notes if,
prior to the Expiration Date, you deliver the following to the appropriate
Exchange Agent:
 
  .  certificates for the Outstanding Notes or a book-entry confirmation of a
     book-entry transfer of the Outstanding Notes into the Exchange Agent's
     account at the Depository Trust Company ("DTC")
 
  .  the Letter of Transmittal (or a facsimile thereof), properly completed
     and duly executed by you, together with any required signature
     guarantees
 
  .  any other documents required by the Letter of Transmittal
 
   You should allow sufficient time to ensure that the Exchange Agents receive
all required documents before the expiration of the Exchange Offers. Neither
the Authority nor the Exchange Agents have any duty to inform you of defects or
irregularities with respect to the tender of your Outstanding Notes for
exchange. See "The Exchange Offers."
 
Forward-Looking Statements
 
   Differences between the Authority's expectations and actual future events
could lead to a material adverse effect on the Mohegan Sun Expansion.
 
   Forward-looking statements are subject to risks, uncertainties and
assumptions about the Authority, and there can be no assurances about the
Authority's current expectations and projections about future events. The
uncertainties include
 
  .  the expansion and construction activities for the new casino, the new
     hotel and the convention center and related upgrades and amenities;
 
  .  the financial performance of the existing casino;
 
  .  its dependence on existing management;
 
  .  its levels of leverage and ability to meet its debt service obligations;
 
  .  general domestic and global economic conditions;
 
  .  changes in federal or state tax laws or the administration of such laws;
 
  .  changes in gaming laws or regulations (including potential legalization
     of gaming in some jurisdictions); and
 
  .  maintenance of licenses required under gaming laws and regulations and
     construction permits and approvals required under applicable laws and
     regulations.
 
   If the Authority's estimates on these types of items differs from actual
future events, there could be a material adverse effects on future operations
and cash flow from those operations.

                              THE EXCHANGE OFFERS
 
Purpose and Effect of the Exchange Offers
 
   In connection with the sale of the Outstanding Notes, the Authority entered
into registration rights agreements with the initial purchasers of the
Outstanding Notes pursuant to which the Authority agreed to file and to use its
best efforts to cause to become effective with the Commission a registration
statement with respect to the exchange of the Outstanding Notes for Exchange
Notes with terms identical in all material respects to the terms of the
Outstanding Notes. Copies of these registration rights agreements have been
filed as an exhibit to the Registration Statement of which this Prospectus is a
part. The Exchange Offers are being made to satisfy the contractual obligations
of the Authority under the registration rights agreements.
 
   By tendering Outstanding Notes in exchange for Exchange Notes, each holder
represents to the Authority that: (1) any Exchange Notes to be received by such
holder are being acquired in the ordinary course of such holder's business; (2)
such holder has no arrangement or understanding with any person to participate
in a distribution (within the meaning of the Securities Act) of Exchange Notes;
(3) such holder is not an "affiliate" of the Authority (within the meaning of
Rule 405 under the Securities Act), or if such holder is an affiliate, that
such holder will comply with the registration and prospectus delivery
requirements of the Securities Act to the extent applicable; (4) such holder
has full power and authority to tender, exchange, sell, assign and transfer the
tendered Outstanding Notes, (5) the Authority will acquire good, marketable and
unencumbered title to the tendered Outstanding Notes, free and clear of all
liens, restrictions, charges and encumbrances; and (vi) the Outstanding Notes
tendered for exchange are not subject to any adverse claims or proxies. Each
tendering holder also will warrant and agree that such holder will, upon
request, execute and deliver any additional documents deemed by the Authority
or the Exchange Agent to be necessary or desirable to complete the exchange,
sale, assignment, and transfer of the Outstanding Notes tendered pursuant to
the Exchange Offers. Each broker-dealer that receives Exchange Notes for its
own account in exchange for Outstanding Notes pursuant to the Exchange Offers,
where such Outstanding Notes were acquired by such broker-dealer as a result of
market-making or other trading activities, must acknowledge that it will
deliver a prospectus in connection with any resale of such Exchange Notes. See
"Plan of Distribution."
 
   The Exchange Offers are not being made to, nor will the Authority accept
tenders for exchange from, holders of Outstanding Notes in any jurisdiction in
which the Exchange Offers or the acceptance of the Exchange Notes would be in
violation of the securities or blue sky laws of that jurisdiction.
 
   Unless the context requires otherwise, the term "holder" with respect to an
Exchange Offer means any person in whose name the Outstanding Notes are
registered on the books of the Authority or any other person who has obtained a
properly completed bond power from the registered holder, or any participant in
DTC whose name appears on a security position listing as a holder of
Outstanding Notes (which, for purposes of the Exchange Offers, include
beneficial interests in the Outstanding Notes held by direct or indirect
participants in DTC and Outstanding Notes held in definitive form).
 
Terms of the Exchange Offers
 
   The Authority hereby offers, upon the terms and subject to the conditions
shown in this Prospectus and in the accompanying Letter of Transmittal, to
exchange $1,000 principal amount of Senior Exchange Notes for each $1,000
principal amount of Outstanding Senior Notes and $1,000 principal amount of
Senior Subordinated Exchange Notes for each $1,000 principal amount of
Outstanding Senior Subordinated Notes, properly tendered before the Expiration
Date and not properly withdrawn according to the procedures described below.
Holders may tender their Outstanding Notes in whole or in part in integral
multiples of $1,000 principal amount.
 
   The form and terms of the Exchange Notes are the same as the form and terms
of the Outstanding Notes except that (1) the Exchange Notes have been
registered under the Securities Act and therefore are not subject to the
restrictions on transfer applicable to the Outstanding Notes and (2) holders of
the Exchange Notes will not be entitled to some of the rights of holders of the
Outstanding Notes under the registration rights agreement. The Exchange Notes
evidence the same indebtedness as the Outstanding Notes (which they replace)
 
                                       26
<PAGE>
 
and will be issued pursuant to, and entitled to the benefits of, the Senior
Notes Indenture and the Senior Subordinated Notes Indenture.
 
   Neither Exchange Offer is conditioned upon the other Exchange Offer or on
any minimum principal amount of Outstanding Notes being tendered for exchange.
The Authority reserves the right in its sole discretion to purchase or make
offers for any Outstanding Notes that remain outstanding after the Expiration
Date in either Exchange Offer or, as shown under "--Conditions to the Exchange
Offers," to terminate, either or both of the Exchange Offers and, to the extent
permitted by applicable law, purchase Outstanding Notes in the open market, in
privately negotiated transactions or otherwise. The terms of any such purchases
or offers could differ from the terms of the Exchange Offers. As of the date of
this Prospectus, $200 million principal amount of Outstanding Senior Notes and
$300 million principal amount of Outstanding Senior Subordinated Notes are
outstanding.
 
   Holders of Outstanding Notes do not have any appraisal or dissenters' rights
in connection with the Exchange Offers. Outstanding Notes which are not
tendered for, or are tendered but not accepted in connection with, the Exchange
Offers will remain outstanding. See "Risk Factors--Risks of Not Complying With
Exchange Offer Procedures."
 
   If any tendered Outstanding Notes are not accepted for exchange because of
an invalid tender, the occurrence of particular other events shown herein or
otherwise, certificates for any such unaccepted Outstanding Notes will be
returned, without expense, to the tendering holder thereof promptly after the
Expiration Date.
 
   Holders who tender Outstanding Notes in connection with the Exchange Offers
will not be required to pay brokerage commissions or fees or, subject to the
instructions in the Letter of Transmittal, transfer taxes with respect to the
exchange of the Outstanding Notes in connection with the Exchange Offers. The
Authority will pay all charges and expenses, other than specified applicable
taxes. See "--Fees and Expenses."
 
   THE AUTHORITY MAKES NO RECOMMENDATION TO THE HOLDERS OF THE OUTSTANDING
NOTES AS TO WHETHER TO TENDER OR REFRAIN FROM TENDERING ALL OR ANY PORTION OF
THEIR OUTSTANDING NOTES IN THE EXCHANGE OFFERS. IN ADDITION, NO ONE HAS BEEN
AUTHORIZED TO MAKE ANY SUCH RECOMMENDATION. HOLDERS OF THE OUTSTANDING NOTES
MUST MAKE THEIR OWN DECISION WHETHER TO TENDER PURSUANT TO THE EXCHANGE OFFERS,
AND, IF SO, THE AGGREGATE AMOUNT OF OUTSTANDING NOTES TO TENDER AFTER READING
THIS PROSPECTUS AND THE LETTER OF TRANSMITTAL AND CONSULTING WITH THEIR
ADVISERS, IF ANY, BASED ON THEIR FINANCIAL POSITION AND REQUIREMENTS.
 
Expiration Date; Extensions; Amendments
 
   The "Expiration Date" for each Exchange Offer is 5:00 p.m., New York City
time, on      , 1999 unless the Exchange Offer is extended by the Authority.
(If the Authority does extend an Exchange Offer, the "Expiration Date" will be
the latest date and time to which that Exchange Offer is extended). Because
neither Exchange Offer is conditioned on the other Exchange Offer, it is
possible that one Exchange Offer could terminate before the other. To the
extent practicable, however, the Authority will seek to terminate both Exchange
Offers at the same time.
 
   The Authority expressly reserves the right in its sole and absolute
discretion, subject to applicable law, at any time and from time to time, (1)
to delay the acceptance of the Outstanding Notes for exchange, (2) to terminate
an Exchange Offer (whether or not any Outstanding Notes have theretofore been
accepted for exchange) if the Authority determines, in its sole and absolute
discretion, that any of the events or conditions referred to under "--
Conditions to the Exchange Offers" has occurred or exists or has not been
satisfied with respect to such Exchange Offer, (3) to extend the Expiration
Date of an Exchange Offer and retain all Outstanding Notes tendered pursuant to
such Exchange Offer, subject, however, to the right of holders of Outstanding
Notes to withdraw their tendered Outstanding Notes as described under "--
Withdrawal Rights," and (4) to waive any condition or otherwise amend the terms
of an Exchange Offer in any respect. If an
 
                                       27
<PAGE>
 
Exchange Offer is amended in a manner determined by the Authority to constitute
a material change, or if the Authority waives a material condition of such
Exchange Offer, the Authority will promptly disclose such amendment by means of
a Prospectus Supplement that will be distributed to the registered holders of
the affected Outstanding Notes, and the Authority will extend the Exchange
Offer to the extent required by Rule 14e-1 under the Exchange Act.
 
   Any such delay in acceptance, termination, extension or amendment will be
followed promptly by oral or written notice thereof to the Exchange Agent for
such Exchange Offer (any such oral notice to be promptly confirmed in writing)
and by making a public announcement, and such announcement in the case of an
extension will be made no later than 9:00 a.m., New York City time, on the next
business day after the previously scheduled Expiration Date. Without limiting
the manner in which the Authority may choose to make any public announcement,
and subject to applicable laws, the Authority shall have no obligation to
publish, advertise or otherwise communicate any such public announcement other
than by issuing a release to an appropriate news agency.
 
Acceptance for Exchange and Issuance of Exchange Notes
 
   Upon the terms and subject to the conditions of each Exchange Offer, the
Authority will exchange, and will issue to the relevant Exchange Agent,
Exchange Notes for Outstanding Notes validly tendered and not withdrawn
(pursuant to the withdrawal rights described under "Withdrawal Rights")
promptly after the Expiration Date.
 
   In all cases, delivery of Exchange Notes in exchange for Outstanding Notes
tendered and accepted for exchange pursuant to each Exchange Offer will be made
only after timely receipt by the relevant Exchange Agent of (1) Outstanding
Notes or a book-entry confirmation of a book-entry transfer of Outstanding
Notes into the appropriate Exchange Agent's account at DTC, (2) the Letter of
Transmittal (or facsimile thereof), properly completed and duly executed, with
any required signature guarantees, and (3) any other documents required by the
Letter of Transmittal. Accordingly, the delivery of Exchange Notes might not be
made to all tendering holders at the same time, and will depend upon when
Outstanding Notes, book-entry confirmations with respect to Outstanding Notes
and other required documents are received by the relevant Exchange Agent.
 
   The term "book-entry confirmation" means a timely confirmation of a book-
entry transfer of Outstanding Notes into the appropriate Exchange Agent's
account at DTC.
 
   Subject to the terms and conditions of each Exchange Offer, the Authority
will be deemed to have accepted for exchange, and thereby exchanged,
Outstanding Notes validly tendered and not withdrawn as, if and when the
Authority gives oral or written notice to the relevant Exchange Agent (any such
oral notice to be promptly confirmed in writing) of the Authority's acceptance
of such Outstanding Notes for exchange pursuant to each Exchange Offer. The
Authority's acceptance for exchange of Outstanding Notes tendered pursuant to
any of the procedures described above will constitute a binding agreement
between the tendering holder and the Authority upon the terms and subject to
the conditions of the Exchange Offers. The Exchange Agents will act as agents
for the Authority for the purpose of receiving tenders of Outstanding Notes,
Letters of Transmittal and related documents, and as agents for tendering
holders for the purpose of receiving Outstanding Notes, Letters of Transmittal
and related documents and transmitting Exchange Notes to holders who validly
tendered Outstanding Notes. Such exchange will be made promptly after the
Expiration Date of each Exchange Offer. If for any reason the acceptance for
exchange or the exchange of any Outstanding Notes tendered pursuant to an
Exchange Offer is delayed (whether before or after the Authority's acceptance
for exchange of Outstanding Notes), or the Authority extends an Exchange Offer
or is unable to accept for exchange or exchange Outstanding Notes tendered
pursuant to an Exchange Offer, then, without prejudice to the Authority's
rights set forth herein, each Exchange Agent may, nevertheless, on behalf of
the Authority and subject to Rule 14e-1(c) under the Exchange Act, retain
tendered Outstanding Notes and such Outstanding Notes may not be withdrawn
except to the extent tendering holders are entitled to withdrawal rights as
described under "--Withdrawal Rights."
 
 
                                       28
<PAGE>
 
Procedures for Tendering Outstanding Notes
 
 Valid Tender
 
   Except as set forth below, in order for Outstanding Notes to be validly
tendered pursuant to an Exchange Offer, either (1) (a) a properly completed and
duly executed Letter of Transmittal (or facsimile thereof), with any required
signature guarantees and any other required documents, must be received by the
appropriate Exchange Agent at the address set forth under "--Exchange Agents"
prior to the Expiration Date and (b) tendered Outstanding Notes must be
received by the Exchange Agents, or such Outstanding Notes must be tendered
pursuant to the procedures for book-entry transfer set forth below and a book-
entry confirmation must be received by the Exchange Agents, in each case prior
to the Expiration Date, or (2) the guaranteed delivery procedures set forth
below must be complied with.
 
   If less than all of the Outstanding Notes are tendered, a tendering holder
should fill in the amount of Outstanding Notes being tendered in the
appropriate box on the Letter of Transmittal. The entire amount of Outstanding
Notes delivered to the Exchange Agents will be deemed to have been tendered
unless otherwise indicated.
 
   If any Letter of Transmittal, endorsement, bond power, power of attorney, or
any other document required by the Letter of Transmittal is signed by a
trustee, executor, administrator, guardian, attorney-in-fact, officer of a
corporation or other person acting in a fiduciary or representative capacity,
such person should so indicate when signing. Unless waived by the Authority,
evidence satisfactory to the Authority of such person's authority to so act
must also be submitted.
 
   Any beneficial owner of Outstanding Notes that are held by or registered in
the name of a broker, dealer, commercial bank, trust company or other nominee
or custodian is urged to contact such entity promptly if such beneficial holder
wishes to participate in the Exchange Offers.
 
   The method of delivery of Outstanding Notes, the Letter Of Transmittal and
all other required documents is at the option and sole risk of the tendering
holder. Delivery will be deemed made only when actually received by the proper
Exchange Agent. Instead of delivery by mail, it is recommended that holders use
an overnight or hand delivery service. In all cases, sufficient time should be
allowed to assure timely delivery and proper insurance should be obtained. No
Letter of Transmittal or Outstanding Notes should be sent to the Authority.
Holders may request their respective brokers, dealers, commercial banks, trust
companies or nominees to effect these transactions for them.
 
 Book-Entry Transfer
 
   Each Exchange Agent will make a request to establish an account with respect
to the applicable Outstanding Notes at DTC for purposes of the applicable
Exchange Offer within two business days after the date of this Prospectus. Any
financial institution that is a participant in DTC's book-entry transfer
facility system may make a book-entry delivery of the Outstanding Notes by
causing DTC to transfer such Outstanding Notes into the relevant Exchange
Agent's account at DTC in accordance with DTC's procedures for transfers.
However, although delivery of Outstanding Notes may be effected through book-
entry transfer into the relevant Exchange Agent's account at DTC, the Letter of
Transmittal (or facsimile thereof), properly completed and duly executed, with
any required signature guarantees and any other required documents, must in any
case be delivered to and received by the relevant Exchange Agent at its address
set forth under "--Exchange Agents" prior to the Expiration Date, or the
guaranteed delivery procedure set forth below must be complied with.
 
   DELIVERY OF DOCUMENTS TO DTC DOES NOT CONSTITUTE DELIVERY TO AN EXCHANGE
AGENT.
 
 Signature Guarantees
 
   Certificates for Outstanding Notes need not be endorsed and signature
guarantees on a Letter of Transmittal or a notice of withdrawal, as the case
may be, are unnecessary unless (a) a certificate for
 
                                       29
<PAGE>
 
Outstanding Notes is registered in a name other than that of the person
surrendering the certificate or (b) a registered holder completes the box
entitled "Special Issuance Instructions" or "Special Delivery Instructions" in
the Letter of Transmittal. In the case of (a) or (b) above, such certificates
for Outstanding Notes must be duly endorsed or accompanied by a properly
executed bond power, with the endorsement or signature on the bond power and on
the Letter of Transmittal or the notice of withdrawal, as the case may be,
guaranteed by a firm or other entity identified in Rule 17Ad-15 under the
Exchange Act as an "eligible guarantor institution," including (as such terms
are defined therein) (1) a bank, (2) a broker, dealer, municipal securities
broker or dealer or government securities broker or dealer, (3) a credit union,
(4) a national securities exchange, registered securities association or
clearing agency, or (5) a savings association that is a participant in a
Securities Transfer Association (each an "Eligible Institution"), unless
surrendered on behalf of such Eligible Institution. See Instruction 1 to the
Letter of Transmittal.
 
 Guaranteed Delivery
 
   If a holder desires to tender Outstanding Notes pursuant to an Exchange
Offer and the certificates for such Outstanding Notes are not immediately
available or time will not permit all required documents to reach the proper
Exchange Agent before the Expiration Date, or the procedures for book-entry
transfer cannot be completed on a timely basis, such Outstanding Notes may
nevertheless be tendered, provided that all of the following guaranteed
delivery procedures are complied with
 
   (1) such tenders are made by or through an Eligible Institution;
 
   (2) prior to the Expiration Date, the relevant Exchange Agent receives from
such Eligible Institution a properly completed and duly executed Notice of
Guaranteed Delivery, substantially in the form accompanying the Letter of
Transmittal, setting forth the name and address of the holder of Outstanding
Notes and the amount of Outstanding Notes tendered, stating that the tender is
being made thereby and guaranteeing that within three New York Stock Exchange
trading days after the date of execution of the Notice of Guaranteed Delivery,
the certificates for all physically tendered Outstanding Notes, in proper form
for transfer, or a book-entry confirmation, as the case may be, and any other
documents required by the Letter of Transmittal will be deposited by the
Eligible Institution with the proper Exchange Agent. The Notice of Guaranteed
Delivery may be delivered by hand, or transmitted by facsimile or mail to the
relevant Exchange Agent and must include a guarantee by an Eligible Institution
in the form set forth in the Notice of Guaranteed Delivery; and
 
   (3) the certificates (or book-entry confirmation) representing all tendered
Outstanding Notes, in proper form for transfer, together with a properly
completed and duly executed Letter of Transmittal, with any required signature
guarantees and any other documents required by the Letter of Transmittal, are
received by the relevant Exchange Agent within three New York Stock Exchange
trading days after the date of execution of the Notice of Guaranteed Delivery.
 
 Determination of Validity
 
   All questions as to the form of documents, validity, eligibility (including
time of receipt) and acceptance for exchange of any tendered Outstanding Notes
will be determined by the Authority, in its sole discretion, which
determination shall be final and binding on all parties. The Authority reserves
the absolute right, in its sole and absolute discretion, to reject any and all
tenders it determines not to be in proper form or the acceptance for exchange
of which may, in the view of counsel to the Authority, be unlawful. The
Authority also reserves the absolute right, subject to applicable law, to waive
any of the conditions of either Exchange Offer as set forth under "--Conditions
to the Exchange Offers" or any defect or irregularity in any tender of
Outstanding Notes of any particular holder whether or not similar defects or
irregularities are waived in the case of other holders.
 
   The Authority's interpretation of the terms and conditions of the Exchange
Offers (including the relevant Letter of Transmittal and the instructions
thereto) will be final and binding on all parties. No tender of Outstanding
Notes will be deemed to have been validly made until all defects or
irregularities with respect to such tender
 
                                       30
<PAGE>
 
have been cured or waived. None of the Authority, any affiliates of the
Authority, the Exchange Agents or any other person shall be under any duty to
give any notification of any defects or irregularities in tenders or incur any
liability for failure to give any such notification.
 
Resales of Exchange Notes
 
   Based on interpretations by the staff of the Commission, as set forth in no-
action letters issued to third parties unrelated to the Authority, the
Authority believes that holders of Outstanding Notes who exchange their
Outstanding Notes for Exchange Notes may offer for resale, resell and otherwise
transfer such Exchange Notes without compliance with the registration and
prospectus delivery provisions of the Securities Act. This would not apply,
however, to any holder that is a broker-dealer that acquired Outstanding Notes
as a result of market-making activities or other trading activities or directly
from the Authority for resale under an available exemption under the Securities
Act. Also, resale would only be permitted for Exchange Notes that are acquired
in the ordinary course of a holder's business, where such holder has no
arrangement or understanding with any person to participate in the distribution
of such Exchange Notes and such holder is not an "affiliate" of the Authority.
The staff of the Commission has not considered the Exchange Offers in the
context of a no-action letter, and there can be no assurance that the staff of
the Commission would make a similar determination with respect to the Exchange
Offers. Each broker-dealer that receives Exchange Notes for its own account in
exchange for Outstanding Notes under the Exchange Offers, where such
Outstanding Notes were acquired by such broker-dealer as a result of market-
making or other trading activities, must acknowledge that it will deliver a
prospectus in connection with any resale of such Exchange Notes. See "Plan of
Distribution."
 
Withdrawal Rights
 
   Except as otherwise provided herein, tenders of Outstanding Notes may be
withdrawn at any time prior to the Expiration Date of an Exchange Offer. In
order for a withdrawal to be effective, such withdrawal must be in writing and
timely received by the relevant Exchange Agent at its address set forth under
"--Exchange Agents" prior to the Expiration Date. Any such notice of withdrawal
must specify the name of the person who tendered the Outstanding Notes to be
withdrawn, the principal amount of Outstanding Notes to be withdrawn, and (if
certificates for such Outstanding Notes have been tendered) the name of the
registered holder of the Outstanding Notes as set forth on the Outstanding
Notes, if different from that of the person who tendered such Outstanding
Notes. If certificates for Outstanding Notes have been delivered or otherwise
identified to the Exchange Agent, the notice of withdrawal must specify the
serial numbers on the particular certificates for the Outstanding Notes to be
withdrawn and the signature on the notice of withdrawal must be guaranteed by
an Eligible Institution, except in the case of Outstanding Notes tendered for
the account of an Eligible Institution. If Outstanding Notes have been tendered
pursuant to the procedures for book-entry transfer set forth in "--Procedures
for Tendering Outstanding Notes," the notice of withdrawal must specify the
name and number of the account at DTC to be credited with the withdrawal of
Outstanding Notes and must otherwise comply with the procedures of DTC.
Withdrawals of tenders of Outstanding Notes may not be rescinded. Outstanding
Notes properly withdrawn will not be deemed validly tendered for purposes of an
Exchange Offer, but may be retendered at any subsequent time prior to the
Expiration Date of such Exchange Offer by following any of the procedures
described above under "--Procedures for Tendering Outstanding Notes."
 
   All questions as to the validity, form and eligibility (including time of
receipt) of such withdrawal notices will be determined by the Authority, in its
sole discretion, which determination shall be final and binding on all parties.
Neither the Authority, any affiliates of the Authority, the Exchange Agents or
any other person shall be under any duty to give any notification of any
defects or irregularities in any notice of withdrawal or incur any liability
for failure to give any such notification. Any Outstanding Notes which have
been tendered but which are withdrawn will be returned to the holder promptly
after withdrawal.

   Interest on the Senior Exchange Notes will be payable every six months on
January 1 and July 1 of each year at a rate of 8 1/8% per annum, commencing
July 1, 1999. The Senior Exchange Notes will mature on

Conditions to the Exchange Offers
 
   If any of the following conditions has occurred or exists or has not been
satisfied prior to the Expiration Date of an Exchange Offer, the Authority will
not be required to accept for exchange any Outstanding Notes and will not be
required to issue Exchange Notes in exchange for any Outstanding Notes. In
addition, the Authority may, at any time and from time to time, terminate or
amend an Exchange Offer (whether or not any Outstanding Notes have theretofore
been accepted for exchange) or may waive any conditions to or amend an Exchange
Offer.
 
  .  A change in the current interpretation by the staff of the Commission
     which permits resale of Exchange Notes as described about under "--
     Resales of Exchange Notes."
 
  .  The institution or threat of an action or proceeding in any court or by
     or before any governmental agency or body with respect to the Exchange
     Offers which, in the Authority's judgment, would reasonably be expected
     to impair the ability of the Authority to proceed with the Exchange
     Offers.
 
  .  The adoption or enactment of any law, statute, rule or regulation which,
     in the Authority's judgment, would reasonably be expected to impair the
     ability of the Authority to proceed with the Exchange Offers.
 
  .  The issuance of a stop order by the Commission or any state securities
     authority suspending the effectiveness of the Registration Statement, or
     proceedings for that purpose.
 
  .  Failure to obtain any governmental approval, which the Authority
     considers necessary for the consummation of the Exchange Offers as
     contemplated hereby.
 
  .  Any change or development involving a prospective change in the business
     or financial affairs of the Authority which the Authority thinks might
     materially impair its ability to proceed with the Exchange Offers.
 
   If the Authority determines in its sole and absolute discretion that any of
the foregoing events or conditions has occurred or exists or has not been
satisfied at any time prior to an Expiration Date, the Authority may, subject
to applicable law, terminate the applicable Exchange Offer (whether or not any
Outstanding Notes have theretofore been accepted for exchange) or may waive any
such condition or otherwise amend the terms of an Exchange Offer in any
respect. If such waiver or amendment constitutes a material change to an
Exchange Offer, the Authority will promptly disclose such waiver or amendment
by means of a prospectus supplement that will be distributed to the registered
holders of the applicable Outstanding Notes. In this case, the Authority will
extend the applicable Exchange Offer to the extent required by Rule 14e-1 under
the Exchange Act.

Fees and Expenses
 
   The expenses of soliciting tenders will be borne by the Authority. The
principal solicitation is being made by mail. Additional solicitation may be
made personally or by telephone or other means by officers, directors or
employees of the Authority.
 
   The Authority has not retained any dealer-manager or similar agent in
connection with the Exchange Offers and will not make any payments to brokers,
dealers or others soliciting acceptances of the Exchange Offers. The Authority
has agreed to pay the Exchange Agents reasonable and customary fees for their
services and will reimburse them for reasonable out-of-pocket expenses in
connection therewith. The Authority will also pay brokerage houses and other
custodians, nominees and fiduciaries the reasonable out-of-pocket expenses
incurred by them in forwarding copies of this Prospectus and related documents
to the beneficial owners of Outstanding Notes, and in handling or tendering for
their customers.
 
   Holders who tender their Outstanding Notes for exchange will not be
obligated to pay any transfer taxes in connection therewith, except that if
Exchange Notes are to be delivered to, or are to be issued in the name of, any
person other than the registered holder of the Outstanding Notes tendered, or
if a transfer tax is imposed for any reason other than the exchange of
Outstanding Notes in connection with the Exchange Offers, then the amount of
any such transfer tax (whether imposed on the registered holder or any other
persons) will be payable by the tendering holder. If satisfactory evidence of
payment of such transfer tax or exemption therefrom is not submitted with the
Letter of Transmittal, the amount of such transfer tax will be billed directly
to such tendering holder.
 
                                USE OF PROCEEDS
 
   The Exchange Offers are intended to satisfy certain obligations of the
Authority under the registration agreements. The Authority will not receive any
cash proceeds from the issuance of the Exchange Notes. In consideration for
issuing the Exchange Notes as contemplated in this Prospectus, the Authority
will receive, in exchange, an equal number of Outstanding Notes in like
principal amount. The form and terms of the Exchange Notes are identical in all
material respects to the form and terms of the Outstanding Notes, except as
otherwise described in the section entiteled "The Exchange Offers--Terms of the
Exchange Offers." The Outstanding Notes surrendered in exchange for the
Exchange Notes will be retired and cancelled and cannot be reissued. A portion
of the proceeds from the offering of the Outstanding Notes has been used to
redeem the 13 1/2% Senior Secured Notes and defease junior subordinated notes.
The remainder of these proceeds will be used to fund the Mohegan Sun expansion
and for general corporate purposes.

(1) As adjusted amounts reflect (a) the sale of the Outstanding Notes and the
    application of the related net proceeds, including the redemption of
    $175.0 million in aggregate principal amount of the 13 1/2% Senior Secured
    Notes and the establishment of a defeasance trust account for the junior
    subordinated notes of the Authority; (b) the release of restricted cash
    balances to the Authority in the amount of $81.3 million; and (c) the
    closing of the Bank Credit Facility with no loan amounts drawn.
(2) This amount reflects $90.0 million of principal and $35.2 million of
    accrued and unpaid interest.
(3) The Authority, in accordance with FASB 5, has recorded a non-cash expense
    and liability for the estimated present value of the Authority's future
    Relinquishment Agreement payment obligations. These payments are based on
    the amount of gross revenue generated by the Authority. As of September
    30, 1998, the present value of this liability was estimated at $549.1
    million, of which $419.1 million was reflected as an extraordinary item in
    the statements of income (loss) and $130.0 million was capitalized on the
    balance sheet as trademarks and other intellectual property acquired as
    part of the Relinquishment Agreement. Recording this liability has created
    negative capital as of September 30, 1998. This liability will be
    reassessed periodically and may require additional non-cash adjustments to
    be recorded in the statement of income (loss). The estimated liability has
    not changed as of December 31, 1998. See the Authority's financial
    statements and the accompanying notes and "Other Material Agreements--
    Relinquishment Agreement with Trading Cove Associates."
(4) Total capitalization is the sum of total debt, capital lease obligations
    and total capital.

(1) The Authority commenced operations at Mohegan Sun on October 12, 1996.
(2) The Authority, in accordance with FASB 5, has recorded a non-cash expense
    and liability for the estimated present value of the Authority's future
    Relinquishment Agreement payment obligations. These payments are based on
    the amount of gross revenue generated by the Authority. As of September 30,
    1998, the present value of this liability was estimated at $549.1 million,
    of which $419.1 million was reflected as an extraordinary item in the
    statements of income (loss), and $130.0 million was capitalized on the
    balance sheet as trademarks and other intellectual property acquired as
    part of the Relinquishment Agreement. Recording this liability has created
    negative capital as of September 30, 1998. This liability will be
    reassessed periodically and may require additional non-cash adjustments to
    be recorded in the statement of income (loss). The estimated liability has
    not changed as of December 31, 1998. See the Authority's financial
    statements and the accompanying notes and "Other Material Agreements--
    Relinquishment Agreement with Trading Cove Associates."
(3) The ratio of earnings to fixed charges is determined by dividing (a)
    earnings before extraordinary items and fixed charges by (b) fixed charges.
    Fixed charges consist of total interest expense, including cash flow
    participation interest relating to the 13 1/2% Senior Secured Notes.
(4) Earnings before extraordinary items, interest, income taxes, depreciation
    and amortization. EBITDA is presented because we believe it is frequently
    used by securities analysts, investors and other interested parties in the
    gaming industry. However, EBITDA should only be read in conjunction with
    all of the Authority's financial data summarized above and its financial
    statements, including the notes, prepared in accordance with GAAP appearing
    elsewhere herein. EBITDA should not be construed as an alternative either
    to (a) income from operations (as determined in accordance with GAAP) as an
    indicator of the Authority's operating performance or (b) cash flows from
    operating activities (as determined according to GAAP) as a measure of
    liquidity. In addition, because the Authority is an instrumentality of a
    sovereign Indian nation, it is not subject to federal or state income tax.
(5) Earnings before extraordinary items, interest, income taxes, depreciation,
    amortization and management fees. Management fees are paid by the Authority
    to Trading Cove Associates pursuant to the terms of its management
    agreement which terminates on January 1, 2000. Until such termination and
    because management fees are subordinate to debt service, the Authority
    believes EBITDAM is a supplemental financial measurement useful in the
    evaluation of its gaming business.
(6) Including restricted cash balances of $74.5 million, $48.5 million, and
    $81.3 million as of September 30, 1998, September 30, 1997 and December 31,
    1998, respectively.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
   The Authority's sole business is the operation of Mohegan Sun, which opened
in October 1996. The growth in the Connecticut gaming market continues to
expand as well as Mohegan Sun's share in this market. The Authority is
currently undertaking an estimated $750 million expansion of Mohegan Sun.
Construction on the expansion began in March, 1999, and the expansion is
expected to be completed in the fall of 2001.
 
Results of Operations
 
 Comparison of Operating Results for the Quarters Ended December 31, 1998 and
 1997
 
   For the quarter ended December 31, 1998, the Connecticut slot market grew at
a rate of 17.3%, reporting a gross slot win of $273.9 million, an increase of
$40.4 million over the period ended December 31, 1997. Mohegan Sun exceeded the
market's growth as it experienced a 30.3% increase in slot win over the same
period in the prior year. Slot revenues of $111.1 million for the quarter ended
December 31, 1998 reflected a slot win per unit per day of $401. Slot win per
unit per day for the quarter ended December 31, 1997 was $311. The slot win
growth of $25.8 million, or 30.3%, over the previous year reflected Mohegan
Sun's growth in slot win market share of 3.8% over the same period in the prior
year.
 
   Gaming revenues totaled $152.7 million for the quarter ended December 31,
1998, marking an increase of $32.9 million, or 27.4%, over the quarter ended
December 31, 1997. The increase in gaming revenues is primarily due to a 17.3%
growth in the Connecticut slot market and the continued growth of the Mohegan
Sun customer base. Membership in the Mohegan Sun Player's Club totaled 975,933
and 663,932 guests as of December 31, 1998 and 1997, respectively.
 
   For the quarter ended December 31, 1998, food and beverage revenues were
$15.0 million, indicating a growth of $2.4 million, or 19.2%, over the prior
year. Retail and other revenues were $13.3 million, a growth of $3.3 million,
or 32.5%, over the same period in the prior year. The increase in non-gaming
revenues is primarily attributed to increased utilization of complimentaries,
the addition of two new retail outlets to the facility in December 1997 and
April 1998 and the opening of the gas station facility in December 1998.
 
   Bingo revenues totaled $3.4 million for the quarter ended December 31, 1998,
representing a $2.5 million increase over the same period in the prior year.
The increase is a result of an improvement in the overall awareness of the
bingo operation in the marketplace.
 
   Promotional allowances totaled $20.6 million for the quarter ended December
31, 1998, representing a $4.4 million, or 26.8%, increase over the prior year.
The increase is attributable to a growth in the Mohegan Sun customer base as
well as an increased utilization of the Mohegan Sun Player's Club complimentary
program. Promotional allowances as a percentage of gaming revenue remained
constant at 13.5% for both the quarters ended December 31, 1998 and 1997.
 
   Total costs and expenses were $130.4 million for the quarter ended December
31, 1998, an increase of $26.1 million, or 25.0%, over the prior year. The
increase in variable expenses is a direct result of an increase in volume as
gross revenues increased by $41.1 million, or 28.6%, partially offset by
improved operating efficiencies in costs such as rent expense and cost of goods
sold.
 
   Gaming costs and expenses were $66.6 million for the quarter ended December
31, 1998, an increase of $10.3 million, or 18.2%, over the same period in the
prior year. The slot win contribution for the quarter ended December 31, 1998
totaled $28.4 million. This represents an increase of $6.4 million over the
same period in the prior year, which is directly attributable to the $25.8
million increase in slot revenues.
 
 
                                       38
<PAGE>
 
   General and administrative costs were $27.6 million for the quarter ended
December 31, 1998. The increase of $3.9 million, or 16.4%, is partially
attributable to marketing and advertising campaigns which increased the length
of stay and frequency of patron visits.
 
   Management fees earned by Trading Cove Associates totaled $13.6 million for
the quarter ended December 31, 1998, an increase of $6.2 million, or 84.3%,
over the fees paid in last year's period. The increase in management fees is a
direct result of the increase in income from operations.
 
   For the quarter ended December 31, 1998, depreciation and amortization
decreased by $131,000, or 2.7%, as compared with the same period in the prior
year. The decrease is primarily attributable to the expensing of financing
fees in fiscal 1998, partially offset by an increase in depreciation for newly
acquired capital assets such as the racebook and gas station facilities.
 
   Income from operations for the quarter ended December 31, 1998 totaled
$33.5 million, compared to $22.9 million in the same period in the prior year.
The year over year increase of $10.6 million, or 46.4%, is primarily due to
the 27.4% increase in gaming revenues and improved operating efficiencies.
 
   Other expense, net is comprised of interest expense minus interest and
other income. Interest expense of $12.8 million for the quarter ended December
31, 1998 represented an increase of $1.0 million, or 8.8%, over the same
period in the prior year. This increase was mainly attributable to an increase
in the cash flow participation interest owed to the holders of the 13 1/2%
Senior Secured Notes, which is derived as a percent of increased earnings
before extraordinary items, interest, taxes, depreciation, amortization and
management fees. The cash flow participation interest is paid to the holders
of the 13 1/2% Senior Secured Notes pursuant to the 13 1/2% Senior Secured
Notes indenture. Interest and other income was $615,000 for the quarter ended
December 31, 1998, a decrease of $33,000, or 5.1%, over the prior year's
period.
 
 Comparison of Operating Results for the Fiscal Year Ended September 30, 1998
 and the Period October 12, 1996 (date of commencement of operations) through
 September 30, 1997
 
   Net revenues for the fiscal year ended September 30, 1998 were $575.1
million compared with $467.8 million reported for the period ended September
30, 1997. The 22.9% increase in net revenues is primarily attributable to
increases in gaming revenue. As the Authority commenced operations on October
12, 1996, fiscal year 1998 included 12 more operating days than the period
ended September 30, 1997.
 
   Gaming revenues totaled $543.9 million for the fiscal year ended September
30, 1998, marking an increase of $103.4 million, or 23.5%, over the period
ended September 30, 1997. The increase in gaming revenues is primarily due to
the growth in the Connecticut slot market and the continued growth of the
Mohegan Sun customer base. The Connecticut slot market grew at a rate of
18.7%, reporting a gross slot win of $1.1 billion, an increase of $168.8
million from fiscal year 1997. The slot win per unit per day for the fiscal
years ended September 30, 1998 and 1997 were $361 and $319, respectively. The
slot win growth of $83.9 million, or 26.8%, over the previous fiscal year
reflected Mohegan Sun's growth in slot win market share of 2.8% over the prior
year. Membership in the Mohegan Sun Player's Club totaled 908,821 and 587,952
guests as of September 30, 1998 and 1997, respectively.
 
   For the fiscal year ended September 30, 1998, food and beverage revenues
were $55.5 million, indicating a growth of $8.6 million, or 18.4%, over the
prior year. Retail and other revenues were $36.3 million, a growth of $14.8
million, or 68.8%, over the prior year. These increases are attributed to
increased utilization of complimentaries and the addition of two new retail
outlets to the facility.
 
   Bingo revenues totaled $5.7 million for the fiscal year ended September 30,
1998, representing a $2.6 million or 83.9%, increase over the prior year. The
increase is a result of improved operating efficiencies as well as an increase
in the overall awareness of the bingo operation.
 
 
                                      39
<PAGE>
 
   Promotional allowances totaled $66.3 million for the fiscal year ended
September 30, 1998, representing a $22.0 million, or 49.7%, increase over the
prior fiscal year. The increase is attributable to an increase in the customer
base as well as an increased utilization of the Mohegan Sun Player's Club
complimentary program. Additionally, promotional allowance as a percentage of
total revenues increased from 8.6% in fiscal 1997 to 10.3% in fiscal 1998.
 
   Total costs and expenses were $439.8 million for the fiscal year ended
September 30, 1998, an increase of $52.0 million, or 13.4%, over the prior
fiscal year. The increase in expenses is a direct result of a 22.9% increase in
net revenues partially offset by improved operating efficiencies.
 
   Gaming costs and expenses were $237.9 million for fiscal year 1998, an
increase of $28.9 million, or 13.8%, over the prior fiscal year. The slot win
contribution for the fiscal year ended September 30, 1998 totaled $102.3
million. This represents an increase of $21.6 million over the prior fiscal
year, which is directly attributable to increased slot revenues.
 
   General and administrative costs were $87.5 million for the fiscal year
ended September 30, 1998. The increase of $9.2 million, or 11.7%, is partially
attributable to more aggressive marketing campaigns associated with efforts to
increase the frequency of patron visits. As a result, food, beverage and retail
expenses for the fiscal year increased by $5.4 million from the prior period.
 
   For the fiscal year ended September 30, 1998, depreciation and amortization
decreased by $14.6 million, or 45.5%, over the prior period. The decrease is
primarily attributable to pre-opening expenditures of $18.2 million that were
fully depreciated over the first 12 months of business operations, partially
offset by an increase in depreciation for newly acquired capital assets.
 
   The Authority incurred $47.4 million in management fees to Trading Cove
Associates for the fiscal year ended September 30, 1998, an increase of $24.2
million, or 104.1%, over fiscal year 1997. The increase in management fees was
a direct result of the increase in operating income.
 
   Income from operations for the fiscal year ended September 30, 1998 totaled
$135.3 million, compared to $80.0 million in the previous period. The year over
year increase is primarily due to an increase in gaming revenues and improved
operating efficiencies.
 
   Other expense, net is comprised of interest expense minus interest and other
income. Interest expense of $50.2 million for the fiscal year ended September
30, 1998 represented an increase of $5.0 million, or 11.2%, over the prior
year. This increase was mainly attributable to an increase in the cash flow
participation interest owed to the holders of the 13 1/2% Senior Secured Notes,
which is derived as a percent of increased earnings before extraordinary items,
interest, taxes, depreciation, amortization and management fees. The cash flow
participation interest is paid to the holders of the 13 1/2% Senior Secured
Notes pursuant to the 13 1/2% Senior Secured Notes indenture. Interest and
other income was $2.4 million for the fiscal year ended September 30, 1998, an
increase of $605,000, or 33.7%, over the prior year.
 
   Extraordinary items include a loss on the early extinguishment of debt of
$332,000 due to the retirement of a capital lease and a $419.1 million expense
associated with an agreement with Trading Cove Associates whereby the Authority
will assume management control of Mohegan Sun. The relinquishment expense was
recorded as a one-time, non-cash charge pursuant to FASB 5 which requires that
the present value of future expenses be recorded as liabilities once they
become reasonably identifiable and quantifiable. This expense is based upon the
Authority's agreement to pay Trading Cove Associates 5% of gross revenues (as
determined under the terms of the Relinquishment Agreement) generated from
Mohegan Sun and from the planned expansion, beginning January 1, 2000 and
ending December 31, 2014. This amount was derived by discounting the present
value of 5% of projected revenues by the Authority's risk free investment rate.
Future payment obligations to Trading Cove Associates will be recorded as
adjustments to cash flow rather than expensed as
 
                                       40
<PAGE>
 
incurred. However, future "centering" of the estimated present value of this
liability may require additional non-cash charges or credits similar in nature
to this one-time charge.
 
Liquidity, Capital Resources and Capital Spending
 
   As of December 31, 1998, the Authority held cash and cash equivalents of
$28.3 million. Cash provided by operating activities for the quarters ended
December 31, 1998 and 1997 were $18.0 million and $10.0 million, respectively.
As of September 30, 1998 and 1997, cash and cash equivalents were $36.3 million
and $40.4 million, respectively. Cash provided by operating activities for the
fiscal year ended September 30, 1998 was $134.6 million, compared with $117.2
million for the fiscal year ended September 30, 1997.
 
   The Authority's capital expenditures for the quarters ended December 31,
1998 and 1997 were $6.1 million and $17.9 million, respectively. For the
quarter ended December 31, 1998, capital expenditures included $2.9 million for
facility improvements and the acquisition of new capital assets, and $3.2
million for construction costs for the on-site gas station facility and the
preliminary stages of the planned expansion of Mohegan Sun. Capital spending
for the quarter ended December 31, 1997 of $17.9 million was comprised of $1.7
million for the purchase of new capital assets, $3.6 million in the settlement
of construction claims with Morse Diesel, Inc., related to the initial
construction of Mohegan Sun, and $12.6 million for the purchase of assets
previously held under operating leases.
 
   During the quarters ended December 31, 1998 and 1997, the Authority, after
meeting its operating expenses and required deposits to reserve funds under the
indenture for the 13 1/2% Senior Secured Notes distributed a total of $11.3
million and $6.4 million, respectively, to the Tribe. As required under the
indenture for the 13 1/2% Senior Secured Notes, the Authority made an excess
cash purchase offer of $51.2 million to all holders of the 13 1/2% Senior
Secured Notes on December 30, 1998. The excess cash purchase offer expired, by
its terms, on January 29, 1999, and none of the holders of the 13 1/2% Senior
Secured Notes accepted the offer. On February 1, 1999, as required, the
Authority made an offer to repurchase in the amount of the excess cash purchase
offer to the holders of the junior subordinated notes. On February 1, 1999, the
holders of junior subordinated notes also rejected the offer. On February 2,
1999, as permitted by the 13 1/2% Senior Secured Notes indenture, the Authority
distributed the excess cash purchase offer amount of $51.2 million to the
Tribe.
 
   On November 15, 1998 and 1997, the Authority made interest payments of $11.8
million each to the holders of the 13 1/2% Senior Secured Notes and payments of
$5.8 million and $4.1 million, respectively, in cash flow participation
interest. There were no cash interest payment requirements on the Junior
Subordinated Notes as interest is accrued and deferred until 50% of the 13 1/2%
Senior Secured Notes are offered to be repurchased or retired.
 
   Capital expenditures were $32.7 million in fiscal year 1998, versus $35.7
million in fiscal year 1997. Capital expenditures for furniture, fixtures and
equipment were $14.0 million and $35.7 million in 1998 and 1997, respectively.
Additional capital expenditures made during 1998 of $8.4 million related to the
commencement of the renovation of the casino's north entry and construction of
the race book and gas station facilities, $0.3 million for preliminary spending
on Mohegan Sun's expansion plans, and $10.0 million for the acquisition of
equipment previously leased under operating leases.
 
   During fiscal 1998, the Authority, after meeting its operating expenses and
required deposits to reserve funds under the indenture for the 13 1/2% Senior
Secured Notes, distributed a total of $72.4 million to the Tribe. As required
under the 13 1/2% Senior Secured Notes indenture, the Authority made an excess
cash purchase offer of $29.1 million to all holders of the 13 1/2% Senior
Secured Notes in January 1998. The holders of the 13 1/2% Senior Secured Notes
rejected the offer which was subsequently offered to the holders of junior
subordinated notes. The holders of junior subordinated notes also rejected the
offer, and, as a result, the funds were distributed to the Tribe.
 
 
                                       41

   On February 7, 1998, the Authority finalized contract negotiations with
Trading Cove Associates to move forward with an expansion of Mohegan Sun, as
described more fully in this Prospectus. The expansion project is currently
estimated to cost $750 million (excluding capitalized interest). The Tribe has
issued a formal resolution capping the scope of the project to an expansion
budget of $800 million. The proposed development plans include approximately
100,000 square feet of additional gaming space, a luxury hotel facility with
approximately 1,500 rooms, an events center with seating for 10,000 guests and
a convention center with approximately 100,000 square feet of space. The
Authority also plans to include additional retail and restaurant facilities
into the design. Current plans would require significant upgrades and additions
to the facility's parking and infrastructure systems. The Tribe has chosen a
project developer, an architect, a site master planner, cost and scheduling
consultants and a retail consultant for the expansion. These firms, in
conjunction with the Tribe and the Authority, are in the process of developing
a construction budget and schedule. As a result, the estimated project cost is
still subject to adjustment. Mohegan Sun's expansion broke ground in March,
1999. Trading Cove Associates will oversee the planning, design and
construction of the expansion at Mohegan Sun and will receive compensation of
$14 million for such services.
 
   Under the terms of the Relinquishment Agreement with Trading Cove
Associates, Trading Cove Associates will continue to manage the existing
property under its current management agreement until December 31, 1999. On
January 1, 2000, the Management Agreement between the Authority and Trading
Cove Associates will terminate, and the Authority will assume all day-to-day
management of Mohegan Sun. The Authority, as a result of the termination of the
Management Agreement, has agreed to pay to Trading Cove Associates 5% of gross
revenues (as defined in the Relinquishment Agreement), generated from Mohegan
Sun and from the planned expansion, beginning January 1, 2000 and ending
December 31, 2014. The liability for these relinquishment payments is estimated
at $549.1 million as of September 30, 1998. The Authority has netted against
its liability $130.0 million which has been capitalized on the balance sheet as
Trademarks and other intellectual property acquired as part of the
Relinquishment Agreement. Recording this liability has created negative capital
as of September 30, 1998. This liability will be reassessed periodically and
may require additional non-cash adjustments to be recorded in the statement of
income (loss). The estimated liability has not changed as of December 31, 1998.
 
   For the remainder of fiscal 1999, the Authority expects capital expenditures
to be approximately $13.4 million on facility improvements and $52.6 million on
existing construction projects. These existing construction project
expenditures include $1.2 million relating to the completion of the gas station
facility and $51.4 million on the expansion of Mohegan Sun. Management believes
that existing cash balances and operating cash flow will provide the Authority
with sufficient resources to meet its capital expenditure requirements with
respect to current operations for at least the next 12 months.
 
   On January 15, 1999, the Authority initiated the Tender Offer and Consent
Solicitation for the repurchase of all $175.0 million aggregate principal
amount outstanding of the 13 1/2% Senior Secured Notes. The offer was extended
twice and expired at 11:59 p.m., New York City time on February 26, 1999. The
tender offer price for the 13 1/2% Senior Secured Notes was $219.9 million.
Holders of 100% of the 13 1/2% Senior Secured Notes accepted the Tender Offer
and Consent Solicitation.
 
   The Tribe established a $40.0 million construction reserve account that, in
specific circumstances, will be used to pay costs in excess of the expansion
budget. The Authority also established a segregated defeasance trust account
with a defeasance agent with cash equivalent funds estimated to be sufficient
to permit redemption of its junior subordinated notes on January 1, 2000.
 
Year 2000
 
 Background
 
   Many computer systems and applications currently use two-digit date fields
to designate a year. As the century date change occurs, date-sensitive systems
will recognize the year 2000 as 1900, or not at all. This
 
                                       42
<PAGE>
 
inability to recognize, or properly treat, the year 2000 may cause systems to
process financial and operational information incorrectly, resulting in system
failures and other business problems.
 
 Risk Factors
 
   The Authority, like many companies, depends on fully operational computer
systems in all areas of its operations. Additionally, the Authority is
dependent upon many vendors to provide uninterrupted service for its operations
to run effectively. Exposure to both of these risk factors are issues for which
the Authority is formulating an approach.
 
 Approach
 
   With the assistance of an outside consultant, the Authority has implemented
a Year 2000 program to provide an independent analysis of the Authority's Year
2000 preparedness and the adequacy of the Authority's Year 2000 plans. The
program includes inventorying entities, identifying problems, planning
compliance, calculating time and cost estimates and generating implementation
strategies, attempting to correct the problems and testing the solutions. The
consultant will examine the methodology being used to approach risks in the
facilities' embedded systems and in products in the Authority's supply chain.
While the Authority's efforts are designed to be successful, because of the
complexity of the Year 2000 issues and the interdependence of organizations
using computer systems, there can be no assurance that the Authority's efforts,
or those of a third party with whom the Authority interacts, will be
satisfactorily completed in a timely fashion. This could result in a material
adverse effect on future operations.
 
 Status
 
   As of March 31, 1999, Mohegan Sun was approximately 75% in conformance with
the GartnerGroup Year 2000 best practices model. The Authority anticipates
completion of the program by June 1999. If at that time it is determined that
the program will not be completed, however, the Authority will develop a
contingency plan.
 
 Cost
 
   The Authority has incurred approximately $100,000 in costs associated with
the Year 2000 Program as of December 31, 1998. The Authority does not
separately track the internal costs incurred for the Year 2000 program, and the
$100,000 of costs incurred through December 31, 1998 are principally related to
payroll costs for the Authority's information systems group and outside
consulting fees. Although there can be no assurances, it is anticipated that
costs associated with the remediation and verification to become Year 2000
compliant will not exceed $1.0 million and will not have a material adverse
impact on the Authority's financial position, results of operations, or cash
flow.
 
State Compact
 
   The Mohegan Compact stipulates that a portion of the revenues earned on slot
machines must be paid to the State of Connecticut. This slot win contribution
will be the lesser of (1) 30% of gross revenues from slot machines, or (2) the
greater of (a) 25% of gross revenues from slot machines or (b) $80.0 million.
 
   The slot win contribution payments are linked to an exclusivity clause and
will not be required if the State of Connecticut legalizes any other gaming
operations with slot machines or other commercial casino table games within
Connecticut (except those consented to by the Tribe and the Mashantucket Pequot
Tribe). The Authority has reflected $102.3 million and $80.7 million,
respectively, of gaming expense on its financial statements for the required
slot win contribution to the State of Connecticut for the fiscal years ended
September 30, 1998 and 1997.

Mohegan Sun
 
   The Authority owns and operates Mohegan Sun, a full-service gaming and
entertainment complex on a 240-acre site overlooking the Thames River on the
Tribe's reservation in southeastern Connecticut. The Authority has entered into
a land lease with the Tribe whereby the Tribe leases to the Authority the site
on which Mohegan Sun is located. Mohegan Sun opened in October 1996 at a total
cost of approximately $303 million. Mohegan Sun and Foxwoods Resort Casino are
the only two legally authorized gaming operations offering both traditional
slot machines and table games in the Northeastern United States outside of
Atlantic City, New Jersey.
 
   For its first fiscal year of operations ended September 30, 1997, Mohegan
Sun welcomed approximately 6.5 million guests and recorded gross revenues of
$512.1 million. During its second fiscal year ended September 30, 1998, Mohegan
Sun had approximately 7.5 million guests, an increase of 15.4% over 1997, and
its gross revenues were $641.4 million, an increase of 25.2% over the prior
year. The Authority's EBITDAM (earnings before extraordinary items, interest,
income taxes, depreciation, amortization and management fees) for the 12 months
ended September 30, 1997 and 1998 were $135.4 million and $200.3 million,
respectively. The Authority's EBITDAM for the quarters ended December 31, 1997
and 1998 were $35.1 million and $51.8 million, respectively.
 
   Mohegan Sun is an approximately 634,500 square foot facility which conveys a
historical northeastern Indian theme through architectural features and the use
of natural design elements such as timber, stone and water. It is comprised of
four quadrants, each of which has its own unique entrance and reflects a
separate seasonal theme--winter, spring, summer and fall--emphasizing the
importance of the seasonal changes to Mohegan Tribal life.
 
   Mohegan Sun has approximately 176,500 square feet of gaming space, 3,025
slot machines, 150 table games (including blackjack, roulette, craps, baccarat,
caribbean stud poker and let it ride), 42 poker tables, and a high-stakes bingo
hall and a recently opened 9,000 square foot simulcasting race book facility.
Food and beverage amenities include the 680-seat Seasons buffet, three full-
service themed gourmet restaurants, a 24-hour coffee shop, a New York style
delicatessen, a 10-station food court featuring international and domestic
cuisine, and multiple full and floor service bars for a total of 1,888
restaurant seats. The 350-seat, 10,000 square foot Wolf Den Lounge located in
the center of the casino hosts musical entertainment seven days a week. Larger
events are currently held in the bingo hall or in temporary facilities
constructed on the grounds of the casino, including entertainment and casino
marketing activities. Six small retail shops covering 2,276 square feet of
space provide shopping opportunities ranging from Mohegan Sun souvenirs to
clothing to cigars. For non-gaming entertainment, Mohegan Sun also offers an
arcade-type recreation area and a child care facility operated by New Horizons
Kids Quest, Inc.
 
   The Authority believes ease of access is one of the important factors that
differentiate Mohegan Sun from the Foxwoods Resort Casino. Mohegan Sun is
located approximately one mile from the interchange of I-395 and Route 2A in
Montville, Connecticut, approximately 10 miles west of the Foxwoods Resort
Casino. The Authority constructed a four-lane access road and entrance/exit
ramps off of Route 2A, giving guests direct access to Interstate 395 and
Interstate 95, the main highways connecting Boston, Providence and New York.
Mohegan Sun has parking spaces for 7,500 guests and for 1,700 employees. The
Authority opened a 4,000-square foot, 16-pump service station and convenience
store in December of 1998. The initial construction of Mohegan Sun included
infrastructure features designed to accommodate future growth. In addition, the
site was master planned to allow for expansion with minimal construction
disruption to existing operations.
 
Strategy
 
   Our overall strategy is to profit from expanding demand in the Northeast
gaming market. Our initial success has resulted primarily from guests living
within 100 miles of Mohegan Sun. Based upon Mohegan
 
                                       44
<PAGE>
 
Sun's results and experience to date, we believe the Northeast gaming market is
strong and that there is significant demand for additional amenities. We expect
to develop Mohegan Sun into a full-scale entertainment and destination resort
and believe that this will increase the number of guests and lengthen their
stays at Mohegan Sun. Specifically, we plan to expand Mohegan Sun's facilities
using the proceeds from this offering and the Bank Credit Facility, along with
internally generated cash flow. The expansion will include additional casino
space, a hotel, a large convention facility, entertainment facilities and
additional retail establishments. We will build the expansion with an effort to
minimize disruption to the existing facility and while Mohegan Sun continues to
operate. In preparation for the expansion and to capture existing demand, we
have recently widened our marketing efforts to include the entire New York City
metropolitan area. We believe that by providing Mohegan Sun with additional
capacity and the ability to capture a share of the overnight market in
connection with our marketing efforts, we will extend Mohegan Sun's market
penetration. We believe that the expansion will create a long-term competitive
advantage for Mohegan Sun in the East Coast gaming market. See "Business--
Competition."
 
The Expansion
 
 Overview
 
   We have approved plans for an expansion which will include an approximately
100,000 square feet of additional gaming space, a luxury hotel with
approximately 1,500 rooms, approximately 100,000 square feet of convention
space, an entertainment complex with seating for up to 10,000, approximately
6,000 additional guest parking spaces, specialty retail shops and uniquely
themed restaurants. The expansion will require significant upgrades and
additions to the facility's parking and infrastructure systems. We have master
planned the layout of the existing facilities and the expansion design so as to
minimize disruption to Mohegan Sun's current operations. The cost of
developing, constructing, equipping and opening the expansion is expected to
total approximately $750 million (excluding capitalized interest). The Tribe
has issued a formal resolution capping the scope of the expansion budget at
$800 million (excluding capitalized interest). In addition, the Tribe has
established a $40 million construction reserve account that, in specific
circumstances, will be used to pay costs in excess of the expansion budget.
 
   The following is a summary of some of the key physical attributes of Mohegan
Sun before and after expansion.

</TABLE>
 
   We believe the market favors expansion now for four reasons: (1) unsatisfied
current demand for gaming space at the existing facility; (2) a growing gaming
market in the Northeast region; (3) length of stay data indicating the need for
a hotel and other amenities; and (4) the need to remain competitive with the
Foxwoods Resort Casino. The expansion is intended to attract a greater number
of guests to the facility, particularly during mid-week periods, and to
increase the amount of time and money guests spend at Mohegan Sun. Historical
results show that the market has successfully absorbed both the opening of
Mohegan Sun in October 1996 and the expansion of Foxwoods, completed in July
1997. Despite the addition of over 3,400 slot machines and 200 gaming tables to
the Connecticut market during Mohegan Sun's first year of operation, Mohegan
Sun's win per position for the fiscal year ended September 30, 1997 was $300,
over 25% higher than Atlantic City's win per position for the twelve months
ended September 30, 1997.
 
 Developer
 
   The Authority has engaged Trading Cove Associates to oversee the planning,
design, construction, furnishing and opening of the expansion. Trading Cove
Associates has been working with the Tribe since 1992
 
                                       45
<PAGE>
 
and assisted the Tribe in obtaining a gaming compact with the State of
Connecticut and numerous governmental approvals for Mohegan Sun. Trading Cove
Associates is 50% owned by Sun Cove Limited, a 100% controlled affiliate of Sun
International Hotels Limited, and 50% by Waterford Gaming L.L.C., whose
principals are primarily engaged in hotel management and real estate
development. Sun International Hotels Limited has extensive experience in the
development, construction, marketing and management of casinos and hotels
throughout the world. Senior management personnel of Sun International Hotels
Limited have been actively engaged in the gaming and lodging industries for the
last 25 years and are responsible for the development and operation of several
world-renowned resorts and casinos including Sun City, The Lost City, The
Carousel Casino, Entertainment World in South Africa and the Atlantis Resort
and Casino in the Bahamas. See "Other Material Agreements--Expansion
Development Services Agreement with Trading Cove Associates."
 
 Other Members of the Development Team
 
   Together with Trading Cove Associates, the Authority is assembling a team of
experienced individuals and firms to develop and build Mohegan Sun's expansion.
In addition to the firms listed below, the Tribe and the project developer are
currently in the process of selecting a construction manager and a retail
developer/manager. In an effort to minimize cost overruns, the Authority plans
to enter into only fixed price contracts with the professionals chosen to plan,
develop, design and build the expansion. Construction is not scheduled to
commence until the spring of 1999 so as to allow the architects to complete all
construction drawings and thereby minimize change orders. The Authority will
also implement other measures seeking to minimize the number of change orders
that could increase the cost of the project. The Authority has chosen the
following firms to assist with the expansion:
 
  .  Kohn Pedersen Fox Associates PC will coordinate the architectural design
     of the expansion facilities. Kohn Pedersen Fox Associates PC is an
     internationally recognized firm and has won numerous design awards,
     including New Construction Building of the Year (1995), Federal Design
     Achievement Award (1995) and the Dallas Urban Design Award (1993). Major
     recent projects include the U.S. Courthouse in Foley Square, New York,
     the Samsung Rodin Museum in Seoul, South Korea and the World Bank
     Headquarters in Washington, D.C.
 
  .  Hanscomb Limited will provide cost, scheduling, planning and other
     consulting services for the expansion. Hanscomb Limited has provided
     cost and scheduling management services since 1946 on national and
     international projects, including the Trump Taj Mahal Convention Center
     Casino and Hotel in Atlantic City and the Lester B. Pearson
     International Airport in Toronto, Canada.
 
  .  EDAW, Inc. has master planned the project to provide for expansion with
     minimal construction disruption to the existing operations. EDAW is an
     internationally recognized architectural firm and has worked on a number
     of well known projects including the Centennial Olympic Park in Atlanta,
     Georgia, Coors Field in Denver, Colorado and the Asia and Pacific Trade
     Center in Fukuoka, Japan.
 
  .  Gordon Brant LV, LLC will be the retail consultant for the expansion.
     Gordon Brant is headed by Sheldon Gordon, who is nationally recognized
     for his ability to create high-profile retail complexes including the
     ancient-Roman themed Forum Shops at Ceasar's Palace in Las Vegas, the
     five level San Francisco Centre and the Beverly Center in Los Angeles,
     California.
 
 Budget
 
   Trading Cove Associates, in consultation with the project architect,
construction manager, cost estimator and retail consultant, will prepare the
formal budget for Mohegan Sun's expansion subject to the Authority's final
approval. The budget will include all costs related to the design, construction
and equipping of the project, plus a contingency of 10% of the hard
construction costs. There will be no allocation of the contingency without
approval by the Authority. In addition, the Authority will be required to
approve any change orders in excess of (1) $750,000 in a single instance; (2)
$3.0 million in the aggregate in any one month; or (3) $12.0 million in the
aggregate for the life of the project.
 
                                       46
<PAGE>
 
 Construction Schedule
 
   The Authority began construction of the expansion in the March, 1999, with
openings scheduled in phases. Phase I, which is expected to be completed in
January of 2000, will include the construction of new patron and employee
parking facilities. Phase II, which is expected to be completed in the summer
of 2001, will include the construction of new casino space and the expansion's
retail component. Phase III, the final phase of the expansion, which is
expected to be completed in the fall of 2001, will include the construction of
the convention and hotel facilities. Trading Cove Associates, and in particular
Sun International Hotels Limited, has demonstrated an ability to fast track
casino development projects. Sun International Hotels Limited's management team
built the $300 million Lost City project in South Africa in 26 months and
completed the $480 million development of Atlantis in the Bahamas in
approximately 28 months, despite the fact that the resort remained open
throughout the construction period. Mohegan Sun was designed, developed,
constructed and opened in 12 months. The Authority can give no assurance,
however, that the expansion will be completed as anticipated.
 
 Regulatory Approvals
 
   The Authority anticipates receiving all necessary approvals for the
agreements relating to the expansion from the federal agencies that oversee
Indian affairs. See "Government Regulation--BIA and NIGC Approvals." In
addition, as described below, the Authority is in the process of obtaining
certain other permits and approvals for the expansion of Mohegan Sun.
 
  .  Plans have been submitted to the U.S. Army Corps of Engineers for
     regulatory activities within an inland wetland. The application has been
     reviewed and the Authority has been informally notified that the
     application complies with all requirements of the general programmatic
     permit. Plans of wetlands mitigation have been submitted and accepted
     and verbal approval has been granted. Final permitting is pending
     submission of an overall site development plan to confirm that no
     additional wetlands impacts will result as a part of this project. The
     Authority expects to receive the necessary permits in a timely fashion.
 
  .  Permits are required for work associated with the upgrade of an existing
     culvert beneath railroad properties located to the east of the expansion
     site. Plans have been submitted to the Connecticut Department of
     Environmental Protection. The Authority expects to receive the necessary
     permits in a timely fashion.
 
  .  The Authority has obtained the necessary approvals for permits from the
     Connecticut Traffic Commission relating to the expansion of Mohegan Sun.
     In connection with the issuance of these permits, the Authority may be
     required to make certain improvements to nearby local roadways. The
     Authority believes these improvements will not cost in excess of $1.5
     million.
 
Management Transition
 
   The Authority engaged Trading Cove Associates to operate, manage and market
Mohegan Sun under a seven-year management contract commencing upon the casino's
opening in October 1996. In anticipation of the expansion of Mohegan Sun, the
Authority and Trading Cove Associates are now mutually terminating the
management and related agreements and are entering into certain new agreements.
Under the Relinquishment Agreement between the Authority and Trading Cove
Associates, the Authority will assume the management, operation and maintenance
of Mohegan Sun beginning on January 1, 2000. The Authority has previously
assumed many of Mohegan Sun's day-to-day management functions, and, under the
Relinquishment Agreement, Trading Cove Associates has committed to work closely
with the Authority to facilitate a smooth and effective transition. The
Authority expects that the senior management of Mohegan Sun, the top three of
whom collectively have 45 years of experience in the gaming and hotel industry,
will remain in place as employees of the Authority with long-term employment
contracts. See "The Authority" and "Other Material Agreements--Relinquishment
Agreement with Trading Cove Associates."
 
 
                                       47
<PAGE>
 
   Since the beginning of operations at Mohegan Sun, members of the Authority's
Management Board have gained experience with the gaming business through
membership on the Business Board of Mohegan Sun. The Business Board consists of
four members, two from the Authority and two from Trading Cove Associates. The
Authority believes this Business Board experience, coupled with the retention
of Mohegan Sun's current management will enable it to successfully manage
Mohegan Sun once Trading Cove Associates' tenure officially ends.
 
Market
 
   The Authority believes that Mohegan Sun's location, ease of access, unique
design and reputation, together with the development and marketing of the
expansion, should enable Mohegan Sun to capture a significant share of the
gaming market in the Northeastern United States. The current market for Mohegan
Sun is primarily day-trip customers from New England and New York. According to
market research reports, in 1998 there were approximately 2.5 million adults
living within 50 miles of Mohegan Sun with an average household income of
$56,000, 10.3 million adults within 100 miles with an average household income
of $67,000 and 22.1 million adults within 150 miles with an average household
income of $64,000. The metropolitan areas of Hartford, New Haven, Springfield,
Worcester, Boston and Providence are within two hours driving time by
interstate highway. New York City is approximately 125 miles from Mohegan Sun.
 
Marketing Strategy
 
   The Authority employs a comprehensive marketing program aimed at
establishing Mohegan Sun as a premier entertainment facility in the
Northeastern United States. Mohegan Sun seeks to distinguish itself by
emphasizing its uniquely themed gaming environment, its superior food
experience in a variety of settings, ease of access and attention to personal
service. The Authority will market the expanded facilities along these same
lines. With the addition of hotel and entertainment amenities, the Authority
will be able to market the Mohegan Sun as a premier destination resort complex.
 
   In the past, the Authority has marketed primarily to guests living within
100 miles of Mohegan Sun. This excludes most of the New York City metropolitan
area. The Authority has recently begun a substantial marketing effort to tap a
wider market, including the entire New York City metropolitan area. As a result
of this marketing effort, the number of guests from New York State has grown
over 50% from the last fiscal year as measured by Mohegan Sun's guest database.
The Authority believes the majority of this increase can be attributed to
guests residing within the New York City metropolitan area and believes the New
York City market shows significant potential for additional growth. The
Authority also believes the expansion, particularly a large hotel, should draw
many additional customers from this and other more distant markets. See
"Business--Marketing Strategy."
 
   Consistent with the current emphasis on the day-trip market, the Authority
organizes regular line and charter bus service to the major metropolitan areas
to attract gaming guests at all levels of play. The development of the casino
expansion, which will add substantial hotel and retail facilities as well as
the increased gaming capacity, will broaden Mohegan Sun's market to include
overnight customers. The Authority has begun to target this overnight market.
The Authority estimates that the current average length of time that guests
spend at Mohegan Sun is 110 minutes. Our strategy is to increase this time
significantly.
 
   The Authority creates market awareness and customer loyalty through a wide
variety of activities such as those listed below:
 
  .  Direct mail to Mohegan Sun's               .  Public relations programs;
     guest database;
                                                .  Sports arena and public
  .  Mohegan Sun Player's Club;                    transportation signage; and
 
  .  Print and broadcast                        .  Billboard signage.
     advertisements;
 
  .  Consumer promotions;
 
                                       48
<PAGE>
 
   The Authority spent a total of $23.3 million on marketing programs during
fiscal year 1998. Of this amount, $2.8 million was spent on print advertising,
$3.5 million on television advertisements, $2.1 million on radio advertising,
$10.7 million on marketing promotions and $4.2 million was spent on various
other advertising media. The Authority believes its marketing activities
contributed to the substantial growth in the Mohegan Sun Player's Club in
fiscal year 1998 as compared to fiscal year 1997. Total membership increased by
65% and active membership increased (defined as one visit per year) by 17%,
with the largest percentage growth coming from guests residing in the New York
metropolitan area.

   [A portion of this page contains an untitled map of the Northeastern United
States from Delaware to Vermont. Mohegan Sun is located in the center of the
map with three concentric circles going out from Mohegan Sun showing geographic
locations that are fifty, one hundred and one hundred and fifty miles from the
casino. The map also shows in bold text the location of certain major
metropolitan areas including Albany, Boston and New York City.]
 
   In addition to the fun and excitement of casino action, the Authority
promotes superior customer service and the quality and value of Mohegan Sun's
food offerings to attract repeat guests. Although Mohegan Sun seeks to
accommodate premium high-stakes players, the Authority does not spend
significant resources targeting the more demanding and costly premium player
market. With the addition of hotel rooms and suites, the Authority may target
higher end domestic customers.
 
                                       49
<PAGE>
 
   The Authority also promotes Mohegan Sun through special events held from
time to time, such as weekly fireworks displays, concerts by nationally known
performers and premier sporting events. The Authority believes it has been
innovative in terms of offering successful entertainment events that attract
guests to Mohegan Sun without the existence of a large dedicated entertainment
venue. The Authority has successfully established the 350-seat "Wolf Den
Lounge," situated strategically in the center of the casino as a popular
musical venue, hosting such artists as INXS, Duran Duran and the Brian Setzer
Orchestra. Performances by nationally known acts such as Ringo Starr, Lyle
Lovett and Tony Bennett were held in the bingo hall. In addition, the "Uncas
Pavillion," a temporary structure erected in Mohegan Sun's parking lot during
the fall months of 1998, hosted sold-out performances by Lynyrd Skynyrd and the
Steve Miller Band and a pay-for-view heavyweight title fight between Lennox
Lewis and Zeljko Mavrovic. We believe these events significantly enhanced our
revenue and profits. With new entertainment, convention, retail and restaurant
facilities provided by the expansion, the Authority anticipates substantially
enhanced promotional marketing opportunities.
 
Competition
 
   The gaming industry is highly competitive. Mohegan Sun currently competes
primarily with the Foxwoods Resort Casino and, to a lesser extent, with casinos
in Atlantic City, New Jersey. Foxwoods is approximately 10 miles from Mohegan
Sun and is the largest gaming facility in the United States in terms of total
gaming positions. It is owned and operated by the Mashantucket Pequot Tribe
under a separate compact with the State of Connecticut. Foxwoods offers a
number of amenities that Mohegan Sun does not offer, including hotel
accommodations, extensive retail shopping and more expansive non-gaming
entertainment offerings. Foxwoods has been in operation for nearly seven years
and may have greater financial resources than the Authority or the Tribe.
 
   Upon the completion of the expansion, the Authority intends to broaden
Mohegan Sun's market beyond day-trip customers to include guests making
overnight or extended stays. This means that Mohegan Sun will begin to compete
for customers with casinos in Atlantic City, New Jersey and, to a lesser
extent, gaming resorts such as those on the Gulf Coast of Mississippi and Las
Vegas, Nevada. Many of these casinos and other gaming resorts have greater
resources and greater name recognition than Mohegan Sun.
 
   Outside of Atlantic City, New Jersey, casino gaming in the northeastern
United States may be conducted only by federally recognized Indian tribes
operating under federal Indian gaming law. Currently, (1) the Oneida Indian
Nation operates Turning Stone Casino Resort in Verona, New York, approximately
270 miles from Mohegan Sun and (2) the St. Regis Mohawk Tribe has initiatives
to develop gaming facilities both on its reservation in Hogansburg, New York
near the Canadian border and at the Monticello raceway in the Catskills,
located approximately 90 miles from New York City. In addition, at least two
other federally recognized tribes in New England are each seeking to establish
gaming operations. Several other tribes in New England are seeking federal
recognition to establish gaming operations. A number of states, including
Connecticut, have also investigated legalizing casino gaming by non-Indians in
one or more locations. The Authority cannot predict whether any of these other
tribes or other efforts to legalize casino gaming will be successful in
establishing gaming operations, and if established, whether such gaming
operations will have a material adverse effect on the Authority's operations.
See "Government Regulation."
 
   The following is an assessment of the competitive prospects in Connecticut,
certain neighboring states and other states in the Northeast.
 
 Connecticut
 
   Currently, only the Tribe and the Mashantucket Pequot Tribe are authorized
to conduct gaming in Connecticut. As required by their state compacts, the
Tribe and the Mashantucket Pequots make semi-annual payments to the State of
Connecticut based on 25% of annual slot win. These payments, which totaled
$276.2 million for the 12 months ended December 31, 1998, are linked to an

operations with slot machines or other casino table games within

Connecticut, unless both tribes consent to such operations. There are currently
at least four tribes in Connecticut that are attempting to gain federal
recognition, a lengthy process managed by the Bureau of Indian Affairs. Two of
these are the Eastern Pequot and/or the Paucatuck Eastern Pequot Tribe, who
share a reservation located next to that of the Mashantucket Pequots. The
federal recognition process for these tribes is proceeding, but it is not clear
if or when recognition will be achieved. Even upon gaining recognition, a tribe
must have land taken into trust by the federal government, negotiate a compact
with the state and construct a facility before it can commence gaming
operations.
 
 Rhode Island
 
   There is no commercial gaming in Rhode Island although the state's two pari-
mutuel facilities, Lincoln Greyhound Park and Newport Grand Jai Alai, offer
approximately 1,800 video slot machines and have petitions pending before the
Rhode Island Lottery Commission for additional machines. In November 1994,
Rhode Island voters defeated numerous local and state-wide gaming referenda and
passed a referendum, which requires that any new gaming proposals will have to
be approved in a state-wide referendum. The Narragansett Tribe is the only
federally recognized Indian tribe in Rhode Island, but under specific federal
legislation the Narragansett Tribe is legally barred from opening a gaming
facility without obtaining both local and state-wide approvals. There is one
pending federal recognition petition from another Rhode Island tribe, filed by
the Pokanoket Tribe of the Wampanoag, located in Bristol, Rhode Island. It is
not clear if or when federal recognition for the Pokanoket Tribe will be
achieved.
 
 Massachusetts
 
   No commercial casinos operate in Massachusetts, and no significant
initiatives to legalize such casinos are currently underway. The Wampanoag
Tribe, located on the island of Martha's Vineyard, is currently the only
federally recognized Indian tribe in the state. This tribe has determined that
a casino on the island would not be economically feasible, and the State
Legislature has rejected proposals to locate an Indian casino off tribal lands.
This tribe originally announced plans to open a high-stakes bingo facility in
Fall River, Massachusetts, but due to significant hurdles, including the
failure to obtain approval from the state legislature, the Wampanoags have
recently been considering other sites in southeastern Massachusetts. In
addition, approximately five other petitions for federal recognition are
pending in Massachusetts. The Tribe believes potential recognition for any of
these tribes is at least several years away.
 
 New York
 
   No non-Indian casinos currently operate in New York and the establishment of
commercial casino operations would require the approval of two successive state
legislatures followed by the voters in a state-wide referendum. However,
gambling boats began operating out of the New York City area in January 1998.
These "cruises to nowhere" during which gaming activities are conducted on
board once the boat is in international waters, three miles offshore, are
permitted under federal law unless prohibited by the state from which they
operate. New York to date has not prohibited such operations. Only a small
number of operators have applied for licenses for off-shore gambling cruises,
and currently these cruises occur primarily in the summer and early fall
months, between June and October. Due to the difference in the gaming
experience, the Authority does not believe the "cruises to nowhere" are
significant competition to Mohegan Sun.
 
   New York has seven federally recognized Indian tribes with reservations. Two
tribes, the Oneida Tribe and the St. Regis Mohawk Tribe, have executed compacts
with the state. These compacts allow casino table games, but no conventional
slot machines. The Oneida Tribe opened the Turning Stone Casino in July 1993 on
its reservation in Verona, near Syracuse. The facility has 3,500 video lottery
machines which operate on a pari-mutuel system as opposed to the traditional
fixed odds reel-type machines operated by most casinos, 150 table games, 285
hotel rooms, a conference center and a golf course. Turning Stone currently
draws primarily from the Syracuse, New York market. The Authority believes
Turning Stone does not pose a material direct
 
                                       51
<PAGE>
 
competition with Mohegan Sun for customers. The St. Regis Mohawk Tribe, which
has a reservation in Hogansburg on the Canadian border, has not yet opened an
on reservation gaming facility. However, this tribe's agreement with a third
party to manage such gaming activities has been approved by the National Indian
Gaming Commission. In addition, the St. Regis Mohawk Tribe and officials from
Sullivan County have also signed an agreement that contemplates the
establishment of a tribally operated casino at Monticello Raceway in the
Catskills, located approximately 170 miles from Mohegan Sun and 90 miles north
of New York City. This estimated $500 million project would require land to be
taken into trust with specific approval from the Bureau of Indian Affairs and
the Governor of New York. While the St. Regis Mohawks have received initial
approval from the Eastern Area Office of the Bureau of Indian Affairs for the
project, final approval from the Central Office of the Bureau of Indian Affairs
is still pending. Furthermore, the Governor has not announced his support for
this project. In addition, the Seneca Nation of Indians have bingo operations
on two of their three reservations in western New York. These bingo halls are
located in Vandalia, and Gowanda, New York, both over 400 miles from Mohegan
Sun. Although preliminary discussions have occurred, the Seneca Indians have
not entered into a compact with the state of New York which would allow this
tribe to expand their gaming operations to include casino games.
 
 Maine
 
   There are no commercial casinos allowed in Maine, and there are no
significant initiatives currently underway to legalize such casinos. There are
four federally recognized tribes in Maine, one of which (the Penobscot Tribe)
has opened a high stakes bingo facility in the township of Albany in western
Maine. None of the federally recognized tribes has negotiated a tribal-state
compact or otherwise significantly begun the process of developing casino
operations.
 
 New Hampshire
 
   There are no casinos allowed in New Hampshire, and there are no significant
initiatives currently underway to legalize casinos. A bill to allow the state's
racetracks to offer slot machines was defeated in a House committee in May
1997, the fourth consecutive time that New Hampshire legislators voted against
gaming expansion. There are no federally recognized Indian tribes in the state
and no petitions for recognition pending.
 
 Vermont
 
   There are no casinos allowed in Vermont, and there are no significant
initiatives currently underway to legalize casinos. There are no federally
recognized tribes in the state, but there is a petition pending from the St.
Francis/Sokoki Band of Abenakis, in Swanton. We believe any approval is still
several years away.
 
Employees and Labor Relations
 
   As of December 31, 1998, Mohegan Sun employed 5,070 full-time employees and
414 seasonal and part-time employees. Pursuant to its Management Agreement with
the Authority, Trading Cove Associates has been responsible for recruiting and
training employees to operate Mohegan Sun. In recruiting personnel, Trading
Cove Associates has been obligated to give preference, first to qualified
members of the Tribe (and qualified spouses and children of members of the
Tribe) and second to members of other Indian tribes. Trading Cove Associates
has developed and implemented training programs to teach Mohegan Sun employees
necessary technical skills as well as to instill a commitment to the highest
levels of service in the industry. Training responsibilities and training
programs have been transitioned to the Authority. The Authority believes that
it will be able to hire and train employees to operate Mohegan Sun during and
after the expansion. Mohegan Sun employees are not covered by any collective
bargaining agreement. The Authority believes its relationship with its
employees is good.
 
                                       52

Environmental Matters
 
   The Authority currently incurs and may continue to incur costs to comply
with environmental requirements such as those relating to discharges to air,
water and land, the handling and disposal of solid and hazardous waste, and the
cleanup of properties affected by hazardous substances. The site of Mohegan Sun
was formerly occupied by United Nuclear Corporation, a naval products
manufacturer of, among other things, nuclear reactor fuel components. United
Nuclear's facility was officially decommissioned on June 8, 1994 when the
Nuclear Regulatory Commission confirmed that all licensable quantities of such
nuclear material had been removed from the site and that any residual
contamination from such material was remediated according to the Nuclear
Regulatory Commission approved decommissioning plan. In addition, environmental
requirements address the impacts of development on wetlands areas. See
"Business--The Expansion."
 
   From 1991 through 1993, United Nuclear commissioned environmental audits and
soil sampling programs which detected, among other things, volatile organic
chemicals, heavy metals and fuel hydrocarbons in the soil and groundwater. The
Connecticut Department of Environmental Protection (DEP) reviewed the
environmental audits and reports and established cleanup requirements for the
site. In December 1994, the DEP approved United Nuclear's remedial plan, which
determined that groundwater remediation was unnecessary because although the
groundwater beneath the site was contaminated, it met the applicable
groundwater criteria given the classification of the groundwater under the
site. In addition, extensive remediation of contaminated soils and additional
investigation were completed to achieve the DEP's cleanup criteria and
demonstrate that the remaining soils complied with applicable cleanup criteria.
Initial construction at the site also involved extensive soil excavation.
According to the data gathered in a 1995 environmental report commissioned by
United Nuclear, remediation is complete and is consistent with the applicable
Connecticut cleanup requirements. The DEP has reviewed and approved the cleanup
activities at the site, and, as part of the DEP's approval, United Nuclear was
required to perform post-closure groundwater monitoring at the site to insure
the adequacy of the cleanup.
 
   In addition, under the terms of United Nuclear's environmental certification
and indemnity agreement with the Department of the Interior (which took the
former United Nuclear land into trust for the Mohegan Tribe), United Nuclear
agreed to indemnify the Department for environmental actions and expenses based
on acts or conditions existing or occurring as a result of United Nuclear's
activities on the property. Notwithstanding the foregoing, no assurance can be
given that any existing environmental studies reveal all environmental
liabilities, or that future laws, ordinances or regulations will not impose any
material environmental liability, or that a material environmental condition
does not otherwise currently exist or will be exposed due to the expansion.
Should soil or groundwater contamination be identified during the course of the
expansion, Connecticut remediation standard requirements will have to be met,
in addition to any other applicable environmental remediation requirements.
 
   Under the Clean Air Act, the State of Connecticut has developed a State
Implementation Plan to ensure the achievement of air quality standards in the
state. In 1995, the Tribe and Trading Cove Associates commissioned a Draft
Environmental Assessment of Mohegan Sun, which concluded that emissions from
Mohegan Sun should not cause significant air quality impacts. The Environmental
Assessment's projection was based in part on the Tribe's and Trading Cove
Associates' pollution prevention plans and ability to obtain emission reduction
credits to offset emissions. Pursuant to the Connecticut State Implementation
Plan, the Tribe and the State of Connecticut in 1996 entered into a voluntary
agreement to offset volatile organic compound and nitrogen oxide emissions
resulting from transportation activity associated with the facility. The Tribe
currently purchases nitrogen oxide emission credits to offset these emissions.
 
   Certain federal, state and local requirements govern the removal,
encapsulation and disturbance of asbestos-containing materials when those
materials are in poor condition or in the event of renovation, remodeling or
demolition. These requirements may impose liability for releases of asbestos-
containing materials and may enable third parties to seek recovery from owners
or operators of properties for personal
 
                                       53
<PAGE>
 
injury associated with such materials. While there is no known asbestos-
containing material on the property, and there is only one remaining
unrenovated building, a full asbestos survey has not been conducted.
 
   In addition to federal, state and local laws relating to hazardous or toxic
substances, the National Environmental Policy Act requires that, before taking
any federal action that may significantly affect the quality of the human
environment, the responsible federal agency must prepare an environmental
impact statement describing and quantifying, to the extent possible, such
effects. Upon the initial construction of Mohegan Sun, the Bureau of Indian
Affairs and the National Indian Gaming Commission determined that an
environmental impact statement was not necessary. The Authority does not
anticipate an environmental impact statement being required for the expansion.
 
Legal Proceedings
 
   The Authority is involved in certain litigation incurred in the normal
course of business. In the opinion of the Authority, the aggregate liability,
if any, arising from such litigation will not have a material adverse effect on
its financial position or results of operations.

                                 THE AUTHORITY
 
General
 
   The Tribe established the Authority in July 1995 to exercise all
governmental and proprietary powers of the Tribe over all gaming related
development. The Authority is governed by a nine-member Management Board which
consists of the same nine members as those of the Tribal Council (the governing
body of the Tribe). Any change in the composition of the Tribal Council results
in a corresponding change in the Authority's Management Board. See "Mohegan
Tribe of Indians of Connecticut."
 
   The Authority has two major functions. The first, delegated to the
Management Board, is to direct the development, operation, management,
promotion and construction of the gaming enterprise and all related
development. The second major function is to regulate gaming. The Management
Board appoints an independent Director of Regulation to ensure the integrity of
the gaming operation through the promulgation and enforcement of appropriate
regulation. The Director of Regulation serves at the pleasure of the Management
Board. The Director of Regulation employs a staff that is responsible for
performing background investigation into gaming license applicants. The
Director of Regulation is also responsible for the issuance and revocation of
gaming licenses. The individual members of the Management Board do not receive
any direct compensation from the Authority. Management Board salaries are paid
by the Tribe.

Business Board
 
   The Authority and Trading Cove Associates have overseen the management of
Mohegan Sun through a Business Board, which reports directly to the Management
Board of the Authority. The Business Board consists of four members, two from
the Authority and two from Trading Cove Associates. The Authority's Business
Board members for the past two years have been (1) the Tribe's Chief of Staff
(with the Deputy Chief of Staff as an alternate) and (2) a member of the
Authority's Management Board. The latter position rotates every six months so
as to give direct gaming enterprise experience to a number of members of the
Authority's Management Board. Trading Cove Associates' Business Board Members
have been the same individuals, one each from Sun International Hotels Limited
and Waterford Gaming L.L.C., for the past two years. As part of the
Relinquishment Agreement, the Business Board will terminate on January 1, 2000.
See "Other Material Agreements--Relinquishment Agreement with Trading Cove
Associates."

<PAGE>
 
                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
   The Tribe provides governmental and administrative services to the Authority
in conjunction with the operation of Mohegan Sun. For the fiscal year ended
September 30, 1998, the Authority incurred $7.7 million of expenses for such
services.
 
   The Tribe, through two limited liability companies, has entered into various
land lease agreements with the Authority for access, parking and related
purposes for Mohegan Sun. These lease payments are approximately $636,000 per
year. The Tribe, through Little People L.L.C., one of its limited liability
companies, has sold approximately $413,000 worth of Native American related
goods to the Authority for resale at its retail location.
 
   Under terms of its agreements with the Authority, Trading Cove Associates
must award service contracts or purchase services from qualified members of the
Tribe if the costs of these services are competitive with the local market and
give hiring preference first to members of the Tribe then to other Native
Americans. The Authority uses McFarland Johnson, Inc. for surveyance, civil
engineering and professional design services. Roland Harris, Chairman of the
Management Board, is a consultant for this firm for a fixed fee. For the fiscal
year ended September 30, 1998, the Authority paid $54,354 in fees to McFarland
Johnson, Inc. The Authority believes the terms of this engagement are
comparable to those that would pertain to an arms length engagement of an
unaffiliated firm. As of September 30, 1998, 190 employees of the Authority
were Mohegan tribal members. See "Other Material Agreements."
 
   The Tribe has established a $40 million construction reserve account that,
in certain circumstances, will be used to pay costs in excess of the expansion
budget.

                    MOHEGAN TRIBE OF INDIANS OF CONNECTICUT
 
General
 
   The Mohegan Tribe of Indians of Connecticut became a federally recognized
Indian tribe in 1994. The Tribe currently has approximately 1,300 members and
approximately 750 adult voting members. Although it only recently received
federal recognition, the Tribe has lived in a cohesive community for hundreds
of years in what is today southeastern Connecticut. The Tribe historically has
cooperated with the United States and is proud of the fact that members of the
Tribe have fought on the side of the United States in every war from the
Revolutionary War to Desert Storm. The Tribe believes that this philosophy of
cooperation exemplifies its approach to developing Mohegan Sun.
 
   Although the Tribe is a sovereign entity, it has sought to work with, and
gain the support of, local communities in establishing Mohegan Sun. For
example, the Tribe gave up its claim to extensive tracts of land that had been
guaranteed by various treaties in consideration for certain agreements in the
Mohegan Compact. As a result, local residents and businesses whose property
values had been clouded by this dispute were able to gain clear title to their
property. In addition, the Tribe has been sensitive to the concerns of the
local community in developing Mohegan Sun. This philosophy of cooperation,
rather than confrontation, has enabled the Tribe to build a solid alliance
among local, state and federal officials to achieve its goal of building
Mohegan Sun.
 
Governance of the Tribe
 
   The Tribe's Constitution provides for the governance of the Tribe by a
Tribal Council, consisting of nine members and a Council of Elders, consisting
of seven members. All members of the Tribal Council and the Council of Elders
are elected by the registered voters of the Tribe and serve terms of five
years. Members of the Tribal Council must be at least 18, and members of the
Council of Elders must be at least 55 when elected. The current terms for the
Tribal Council and the Council of Elders expire in October 2000. The members of
the Tribal Council are the same individuals who serve on the Management Board
of the Authority. See "The Authority--Management Board and Executive Officers."
 
   The Tribe's Constitution vests all legislative and executive powers of the
Tribe in the Tribal Council. These powers include the powers to establish an
executive branch departmental structure with agencies and sub-divisions and
delegate appropriate powers to such agencies and sub-divisions.
 
   The Council of Elders acts in the capacity of an appellate court of final
review and may hear appeals of any case or controversy arising under the
Tribe's Constitution, except those matters which relate to Mohegan Sun,
including the Notes, which are required to be submitted to the Gaming Disputes
Court.
 
Gaming Disputes Court
 
   The Tribal Council has established the Gaming Disputes Court by Tribal
ordinance and vested it with exclusive jurisdiction for the Tribe over all
disputes related to gaming at Mohegan Sun. The Gaming Disputes Court is
composed of a Trial Division and an Appellate Branch. A single judge presides
over cases at the trial level. Trial Division decisions can be appealed to the
Appellate Branch where they will be heard by a panel of three judges, one of
whom will be the Chief Judge, and none of whom shall have presided over the
case below. Decisions of the Appellate Branch are final, and no further appeal
is available in the Gaming Disputes Court.
 
   The Gaming Disputes Court has jurisdiction over all disputes or
controversies related to gaming between any person or entity and the Authority,
the Tribe or Trading Cove Associates. The Gaming Disputes Court also has
jurisdiction of all disputes arising out of the Authority's regulatory powers,
including licensing actions. The Tribe has adopted the substantive law of the
State of Connecticut as the applicable law of the Gaming Disputes Court to the
extent such law is not in conflict with Mohegan Tribal Law. Also, the Tribe has
adopted all of Connecticut's rules of civil and appellate procedure,
professional and judicial conduct to govern the Gaming Disputes Court.

   Judges of the Gaming Disputes Court are chosen by the Tribal Council from a
publicly available list of eligible retired federal judges and Connecticut
Attorney Trial Referees, who are appointed by the Chief Justice of the
Connecticut Supreme Court, each of whom must remain licensed to practice law in
the State of Connecticut. Judges are selected sequentially from this list as
cases are filed with the clerk of the Gaming Disputes Court. The Chief Judge of
the Gaming Disputes Court, who serves as the Gaming Disputes Court's
administrative superintendent, is chosen by the Tribal Council from the list of
eligible judges and serves a five-year term. Judges of the Gaming Disputes
Court are subject to discipline and removal for cause pursuant to the rules of
the Gaming Disputes Court. The Chief Judge is vested with the sole authority to
revise the rules of the Gaming Disputes Court. Judges are compensated by the
Tribe at an agreed rate of pay commensurate with their duties and
responsibilities. Such rate cannot be diminished during a judge's tenure.

                           OTHER MATERIAL AGREEMENTS
 
   The following discussion summarizes significant terms of certain material
agreements to which either the Tribe or the Authority are parties. This summary
does not purport to be complete and is qualified in its entirety by reference
to each of the full agreements. The Authority will provide you a copy of any of
these agreements without charge upon written or oral request by contacting the

Gaming Compact with the State of Connecticut
 
   The Tribe and the State of Connecticut agreed in April 1994 to resolve all
land disputes and differences and enter into a gaming compact to authorize and
regulate the Tribe's conduct of gaming on the Tribe's lands. This agreement,
the Mohegan Compact, is substantively similar to the agreement governing gaming
operations of the Mashantucket Pequot Tribe in Connecticut and provides, among
other things, as follows:
 
     (1) The Tribe is authorized to conduct certain Class III gaming
  activities on its reservation. The forms of Class III gaming authorized
  under the Mohegan Compact include (i) certain games of chance, (ii) video
  facsimiles of such authorized games of chance (i.e., slot machines), (iii)
  off-track pari-mutuel betting on animal races, (iv) pari-mutuel betting,
  through simulcasting, on animal races and (v) certain types of pari-mutuel
  betting on games and races conducted at the gaming facility (some types of
  which currently are, together with off-track pari-mutuel telephone betting
  on animal races, under a moratorium).
 
     (2) The Tribe must establish standards of operations and management of
  all gaming operations to protect the public interest, insure the fair and
  honest operation of gaming activities and maintain the integrity of all
  Class III gaming activities. The first of such standards were shown in the
  Mohegan Compact and approved by the State gaming agency. State gaming
  agency approval is required for any revision to such standards. The Tribe
  must supervise the implementation of these standards by regulation through
  a Tribal gaming agency.
 
     (3) Law enforcement matters relating to the Tribe's Class III gaming
  activities will be under the jurisdiction of both the State and the Tribe.
 
     (4) All gaming employees must obtain and maintain a gaming license
  issued by the State gaming agency.
 
     (5) Any enterprise providing gaming services or gaming equipment to the
  Tribe is required to hold a current valid registration issued by the
  Connecticut Division of Special Revenue.
 
     (6) The State will assess the Tribe annually for the costs attributable
  to the State's regulation of the Tribe's gaming operations and for the
  provision of law enforcement at the Tribe's gaming facilities.
 
     (7) Net revenues from the Tribe's gaming operations may be applied only
  for the certain purposes related to Tribal operations and welfare,
  charitable contributions and payments to local governmental agencies.
 
     (8) Tribal ordinances and regulations governing health and safety
  standards at the gaming facilities may be no less rigorous than the
  applicable laws and regulations of the State.
 
     (9) Service of alcoholic beverages within the Tribe's gaming facilities
  is subject to regulation by the State.
 
     (10) The Tribe waives any defense which it may have by virtue of
  sovereign immunity with respect to any action in United States District
  Court to enforce the Mohegan Compact.
 
 
                                       61
<PAGE>
 
   In addition, together with the Mohegan Compact, the Tribe and the State
entered into a memorandum of understanding providing for the payment of a
portion of the Authority's slot machine revenues to the State. Commencing July
1, 1995, for each fiscal year such payment to the State must be the lesser of
(a) 30% of gross revenues from slot machines, or (b) the greater of (i) 25% of
gross revenues from slot machines or (ii) $80.0 million. These payments will
not be required if there is a change in the law to permit the operation of
commercial casino games by any other person in the State (other than the
Mashantucket Pequot Tribe and the Mohegan Tribe). The Authority expensed $102.3
million for the slot win contribution to the State for the fiscal year ended
September 30, 1998.
 
Agreement with the Town of Montville
 
   In June 1994, the Tribe and the neighboring town of Montville entered into
an agreement whereby the Tribe makes annual payments of $500,000 to the town to
minimize the impact to Montville resulting from decreased tax revenues on the
land taken into trust for the Tribe's reservation. The Tribe also agreed to pay
Montville $3.0 million for infrastructure improvements to the town's water
system and to pay for its use of the town's disposal and wastewater collection
and treatment systems. Finally, the Tribe agreed to make payments instead of
taxes to Montville on lands that the Tribe acquires outside of its current
reservation. The Tribe has assigned its rights and obligations under this
agreement to the Authority.
 
Land Lease from the Tribe to the Authority
 
   The land in Uncasville, Connecticut upon which Mohegan Sun is situated and
the expansion will be constructed is held in trust for the Tribe by the United
States of America. The Tribe and the Authority have entered into a land lease
under which the Tribe is leasing to the Authority the property and all
buildings, improvements and related facilities (e.g., Mohegan Sun and the
expansion) constructed or installed on the property. The lease was approved by
the Secretary of the Interior. Below we summarize certain key provisions of
this lease.
 
 Term
 
   The term of the lease is for 25 years with an option, exercisable by the
Authority, to extend the term for one additional 25-year period. Upon the
termination of the lease, the Authority will be required to surrender to the
Tribe possession of the property and improvements, excluding any equipment,
furniture, trade fixtures or other personal leased property.
 
 Rent; Expenses
 
   The Authority is required to pay to the Tribe annual rent in the amount of
$1.00. For any period when the Tribe or another agency or instrumentality of
the Tribe is not the tenant under the lease, the rent will be 8% of the
tenant's gross revenues from the premises. The Authority is responsible for the
payment of all costs of owning, operating, constructing, maintaining,
repairing, replacing and insuring the leased property.
 
 Use of Leased Property
 
   The Authority may use the leased property and improvements solely for the
construction and operation of Mohegan Sun, unless prior approval is obtained
from the Tribe for any proposed alternative use. Similarly, no construction or
alteration of any building or improvement located on the leased property by the
Authority may be made unless complete and final plans and specifications
therefor have been approved by the Tribe. Following foreclosure of any mortgage
on the Authority's interest under the lease or any transfer of such interest to
the holder of such mortgage instead of foreclosure, the leased property and
improvements may be used for any lawful purposes, subject only to applicable
codes and governmental regulations; provided, however, that a non-Indian holder
of the leased property may in no event conduct gaming operations thereon.
 
                                       62
<PAGE>
 
 Permitted Mortgages and Rights of Permitted Mortgagees
 
   The Authority may not mortgage, pledge or otherwise encumber its leasehold
estate in the leased property except to a holder of a permitted mortgage. Under
the lease, a "permitted mortgage" includes the leasehold mortgage securing the
Authority's obligations under the Bank Credit Facility as well as any other
mortgage granted by the Authority that provides, among other things, that (1)
the Tribe shall have the right to notice of, and to cure, any default of the
Authority thereunder, (2) the Tribe shall have the right to prior notice of an
intention by the holder to foreclose on such permitted mortgage and the right
to purchase such mortgage instead of any foreclosure, and (3) such permitted
mortgage is subject and subordinated to any and all access and utility
easements granted by the Tribe under the lease. As provided in the lease, each
holder of a permitted mortgage has the right to notice of any default of the
Authority under the lease and the opportunity to cure such default within any
applicable cure period.
 
   Under the lease, the Tribe and the Secretary of the Interior have consented
to the assignment and transfer by the Authority of its interest in the lease to
any holder of a permitted mortgage under (1) a foreclosure by such holder, (2)
a transfer instead of foreclosure, (3) the exercise of any right or remedy
granted by such holder or (4) any purchase by a third party at a foreclosure or
other sale. In no event, however, will a holder of a permitted mortgage (or any
assignee, sublessee, purchaser or transferee of such holder) be permitted to
transfer any interest in the lease or its leasehold interest in the leased
property and improvements to any person or entity engaged by the Tribe or the
Authority to manage a gaming enterprise.
 
 Default; Remedies
 
   The Authority will be in default under the lease if, subject to certain
notice provisions, it fails to make lease payments or to comply with its
covenants under the lease or if it pledges, encumbers or conveys its interest
in the lease in violation of the terms of the lease. Following a default, the
Tribe may, with approval from the Secretary of the Interior, terminate the
Lease unless a permitted mortgage remains outstanding with respect to the
leased property. In that case, the Tribe may not (1) terminate the lease or the
Authority's right to possession of the leased property, (2) exercise any right
of re-entry, (3) take possession of and/or relet the leased property or any
portion thereof, or (4) enforce any other right or remedy which may materially
and adversely affect the rights of the holder of the permitted mortgage, unless
the default triggering such rights was a monetary default which such holder
failed to cure after notice.
 
Expansion Development Services Agreement with Trading Cove Associates
 
 General
 
   The Authority entered into a Development Services Agreement with Trading
Cove Associates on February 7, 1998 whereby Trading Cove Associates agreed to
oversee the design, construction, furnishing, equipping and staffing of the
casino expansion for a $14.0 million development fee.
 
 Design Phase--Architect and Construction Manager Selection; Plans and
 Specifications
 
   During the design phase, Trading Cove Associates will assist the Authority
in the engagement of the architect and the construction manager, the
preparation of design, construction, and furnishings budgets, preliminary
program evaluation, design development and the approval of final detailed plans
and specifications prepared by the architect. The Authority has chosen Kohn
Pedersen Fox Associates PC as the architect for the expansion. The Authority
has agreed to assign to Trading Cove Associates its responsibilities under any
architectural and/or engineering agreements to allow Trading Cove Associates to
supervise and administer directly the duties of the architect and/or engineer
thereunder.
 
   The Development Agreement provides that the design and construction of the
expansion must comply with all federal and Connecticut statutes and regulations
that otherwise would apply if the expansion were located outside the
jurisdictional boundaries of the Tribe's land.
 
 
                                       63
<PAGE>
 
 Construction Phase
 
   During the construction phase, Trading Cove Associates will be responsible
for the administration and supervision of the construction manager and the
entire construction process. Trading Cove Associates will act as the
Authority's representative in connection with construction contracts that are
approved by the Authority. Specifically, Trading Cove Associates will be
responsible for overseeing all persons performing work on the expansion site,
inspecting the progress of construction, determining completion dates and
reviewing contractor payment requests submitted to the Authority. The
Development Agreement specifically gives Trading Cove Associates the right to
include provisions in construction contracts that impose liquidated damage
payments in the event of failure to meet construction schedules.
 
 Retail Facilities
 
   As permitted by the Development Agreement, the Authority has elected to
engage a retail consultant to oversee the design and construction of the retail
facilities in the expansion. This work will be under the overall supervision of
Trading Cove Associates, which will integrate the design and construction of
the retail facilities with that of the other components of the expansion.
 
 Engagement of Certified Entities; Staffing the Expansion
 
   The Development Agreement requires Trading Cove Associates to implement
procedures described in the Tribal Employment Rights Ordinance. In effect, this
requires Trading Cove Associates to give preference to business entities or
persons which have been approved by the Authority in the selection of all
contractors, vendors and suppliers engaged in the development of the expansion.
In addition, in staffing the operation of the expansion, the Development
Agreement requires that Trading Cove Associates give preference to qualified
members of the Tribe (and their spouses and children) and thereafter to
enrolled members of other federally recognized Indian tribes.
 
 Equipping the Expansion
 
   The Authority will purchase equipment, furniture and furnishings required to
operate the expanded facilities from vendors selected by Trading Cove
Associates or lease such equipment, furniture and furnishings on terms arranged
by Trading Cove Associates and approved by the Authority.
 
 Payment of the Development Fee
 
   The Authority will pay a portion of the development fee to Trading Cove
Associates quarterly beginning on January 15, 2000 until the completion date of
the expansion, such quarterly payment to be based on incremental completion of
the expansion as of each payment date.
 
 Termination and Disputes
 
   The Development Agreement terminates after the earlier of completion of the
expansion or 10 years. In addition, each party has the right to terminate the
Development Agreement if there is a default or failure to perform by the other
party. The parties must submit disputes arising under the agreement to
arbitration and have agreed that punitive damages may not be awarded to either
party by any arbitrator. The Authority has also waived sovereign immunity for
the purposes of permitting, compelling or enforcing arbitration and has agreed
to be sued by Trading Cove Associates in any court of competent jurisdiction
for the purposes of compelling arbitration or enforcing any arbitration or
judicial award arising out of the Development Agreement.

Relinquishment Agreement with Trading Cove Associates
 
 General
 
   Under a relinquishment agreement dated February 7, 1998, the Authority and
Trading Cove Associates have agreed to terminate the existing agreement with
Trading Cove Associates under which Trading Cove Associates manages the
Authority's gaming operations (described in greater detail in the following
section). This termination will occur as of January 1, 2000, at which time the
Authority will assume day-to-day management of Mohegan Sun. To compensate
Trading Cove Associates for terminating its management rights, the Authority
has agreed to pay to Trading Cove Associates 5% of the gross revenues generated
by Mohegan Sun and the planned expansion during the 15-year period commencing
on January 1, 2000.
 
 Relinquishment Payments
 
   The payments under the Relinquishment Agreement will be divided into Senior
Relinquishment Payments and Junior Relinquishment Payments, each of which will
be 2.5% of "Revenues," as defined in the Relinquishment Agreement. Senior
Relinquishment Payments will be payable quarterly in arrears commencing on
April 25, 2000 and the Junior Relinquishment Payments will be payable semi-
annually in arrears commencing on July 25, 2000. "Revenues" are defined as
gross gaming revenues (other than Class II gaming revenue) and all other
facility revenues (including, without limitation, hotel revenues, food and
beverage sales, parking revenues, ticket revenues and other fees or receipts
from the convention/events center in the expansion and all rental or other
receipts from lessees, licensees and concessionaires operating in the facility
but not the gross receipts of such lessees, licensees and concessionaires).
 
 Subordination of Relinquishment Payments/Minimum Priority Distribution to the
 Tribe
 
   The Relinquishment Agreement provides that each of the Senior and Junior
Relinquishment Payments are subordinated in right of payment to payment of
senior secured obligations, including the Bank Credit Facility, and that the
Junior Relinquishment Payments are further subordinated to payment of all other
senior obligations, including the Senior Exchange Notes. The Relinquishment
Agreement also provides that all relinquishment payments are subordinated in
right of payment to an annual minimum priority distribution of $14 million to
the Tribe from the operations of Mohegan Sun. The minimum priority distribution
will be adjusted annually to reflect the cumulative increase in the Consumer
Price Index.
 
 Covenants of the Authority
 
   Under the Relinquishment Agreement, the Authority makes certain covenants
for the benefit of Trading Cove Associates, including the following.
 
     (1) Payments to Tribe. Except for payments of the minimum priority
  distributions and reasonable charges for utilities or other governmental
  services supplied by the Tribe to the Authority, the Authority may not make
  any distributions to the Tribe or its members at any time any
  Relinquishment Payments are outstanding.
 
     (2) Affiliate Transactions. Except for payments of the minimum priority
  distributions and reasonable charges for utilities or other governmental
  services supplied by the Tribe to the Authority, the Authority agrees to
  abide by certain restrictions on transactions with the Tribe and its
  members, all as shown in the Relinquishment Agreement.
 
     (3) Replacement/Restoration of Mohegan Sun. If any portion of Mohegan
  Sun's facilities is damaged by fire or other casualty, the Authority shall
  replace or restore such facilities to substantially the same condition as
  before such casualty, but only to the extent insurance proceeds are
  available to do so. If sufficient insurance proceeds are not available, the
  Authority will use reasonable efforts to obtain the required financing, on
  commercially reasonable terms, to undertake and complete such replacement
  or restoration.
 
                                       65
<PAGE>
 
     (4) Business Purpose. The Authority has agreed that during the term of
  the Relinquishment Agreement it will only engage in the casino gaming and
  resort business (and any incidental business or activity) and will continue
  to operate Mohegan Sun as currently operated.
 
 Orderly Transition/Employee Solicitation
 
   Under the Relinquishment Agreement, the Authority and Trading Cove
Associates agree to cooperate with each other to effect an orderly transition
of the operations of Mohegan Sun to the Authority. Each of the parties also
agrees that it will not solicit any employee of the other party or any
affiliate of the other party for five years.
 
 Marks
 
   Trading Cove Associates has granted to the Authority an exclusive and
perpetual license with respect to trademarks and other similar rights,
including the "Mohegan Sun" name, used at or developed for Mohegan Sun. The
Authority has agreed, however, that it will only use the word "Sun" in
conjunction with the Mohegan Sun resort and together with "Mohegan" or "Mohegan
Tribe."
 
 Waiver of Immunity from Unconsented Suit
 
   With certain limitations shown in the Relinquishment Agreement, both the
Tribe and the Authority waive immunity from unconsented suit for certain
enforcement rights of Trading Cove Associates arising under the Relinquishment
Agreement.
 
Existing Management Agreement with Trading Cove Associates
 
 General
 
   Until January 1, 2000, Trading Cove Associates will continue as the
exclusive manager of Mohegan Sun. Under the Management Agreement, Trading Cove
Associates is responsible for the day-to-day management, operation and
maintenance of Mohegan Sun. Trading Cove Associates is obligated to manage and
operate the facility in compliance with all Tribal legal requirements and other
applicable laws. Certain major decision-making and oversight duties have been
delegated to the Business Board, a committee comprised of an equal number of
representatives of the Authority and of Trading Cove Associates. Actions by the
Business Board require the unanimous approval of its members or their
respective designees.
 
 Staffing the Facility
 
   Trading Cove Associates has the exclusive responsibility and authority to
select, retain, train and discharge all employees hired to perform services at
Mohegan Sun; however, all employees are the employees of the Authority and not
Trading Cove Associates. It is anticipated that substantially all of these
employees will remain in place following termination of the Management
Agreement. Members of the Tribe are to be given preference in the recruiting,
employment and training of personnel in all job categories in connection with
the operation of Mohegan Sun.
 
 Operating and Capital Budgets; Replacement Reserve Fund
 
   Trading Cove Associates must annually submit to the Tribal Council, for its
approval, a detailed proposed annual operating budget for the facility. In
addition to an annual operating budget, Trading Cove Associates must annually
submit to the Tribal Council, for its approval, a recommended annual capital
budget for the furnishings, equipment and ordinary capital replacement items
required to operate Mohegan Sun. Trading Cove Associates must manage and
operate the facility according to the then-current approved operating budget
and capital reserve budget. The Management Agreement further requires Trading
Cove Associates to establish a
 
                                       66
<PAGE>
 
replacement reserve fund for the purpose of funding approved budgeted capital
expenditures. This Reserve Fund is funded monthly by the Authority and Trading
Cove Associates according to a schedule determined by the Business Board, with
all required amounts (up to an aggregate total of $3 million) being funded 60%
by the Authority and 40% by Trading Cove Associates. The Authority's deposits
to the Reserve Fund are deemed capital expenditures and do not reduce Net
Revenues (as defined in the Management Agreement); deposits made on behalf of
Trading Cove Associates reduce monthly management fee amounts distributable to
Trading Cove Associates.
 
 Books and Records; Accounting Procedures
 
   The Management Agreement requires Trading Cove Associates to maintain,
according to generally accepted accounting principles, books and records
reflecting the operations of Mohegan Sun and to prepare monthly, quarterly and
annual statements for the Authority. An annual audit of Mohegan Sun is required
by a nationally-recognized independent certified public accounting firm with
experience in the casino industry.
 
 Management Fee
 
   The Management Agreement authorizes Trading Cove Associates to pay itself a
management fee in monthly installments based on 30% to 40% of Net Revenues
depending on profitability levels. "Net Revenues" are generally defined as
gross gaming revenues (other than Class II gaming revenue) and all other
facility revenues, less operating expenses other than the management fee. The
management fees for the 12 months ended September 30, 1998 and for the quarter
ended December 31, 1998 were $47.4 million and $13.6 million, respectively.
 
                                       67
<PAGE>
 
                             GOVERNMENT REGULATION
 
General
 
   The Authority is subject to special federal, state and tribal laws
applicable to both commercial relationships with Indians generally and to
Indian gaming and the management and financing of Indian casinos specifically.
In addition, the Authority is regulated by federal and state laws applicable to
the gaming industry generally and to the distribution of gaming equipment. The
following description of the regulatory environment in which gaming takes place
and in which the Authority operates is only a summary and not a complete
recitation of all applicable law. Moreover, since this particular regulatory
environment is more susceptible to changes in public policy considerations than
others, it is impossible to predict how certain provisions will be interpreted
from time to time or whether they will remain intact. Changes in such laws
could have a material adverse impact on the Authority's operations. See "Risk
Factors."
 
Tribal Law and Legal Systems
 
 Applicability of State and Federal Law
 
   Federally recognized Indian tribes are independent governments, subordinate
to the United States, with sovereign powers, except as those powers may have
been limited by treaty or by the United States Congress. The power of Indian
tribes to enact their own laws to regulate gaming derives from the exercise of
tribal sovereignty. Indian tribes maintain their own governmental systems and
often their own judicial systems. Indian tribes have the right to tax persons
and enterprises conducting business on Indian lands, and also have the right to
require licenses and to impose other forms of regulations and regulatory fees
on persons and businesses operating on their lands.
 
   Absent the consent of the Tribe or the United States Congress, the laws of
the State of Connecticut do not apply to the Tribe or the Authority. Under the
federal law that recognizes the Tribe, the Tribe consented to the extension of
Connecticut criminal law and Connecticut state traffic controls over Mohegan
Sun.
 
 Waiver of Sovereign Immunity; Jurisdiction; Exhaustion of Tribal Remedies
 
   Indian tribes enjoy sovereign immunity from unconsented suit similar to that
of the states and the United States. To sue an Indian tribe (or an agency or
instrumentality of an Indian tribe, such as the Authority), the tribe must have
effectively waived its sovereign immunity with respect to the matter in
dispute. Further, in most commercial disputes with Indian tribes, the
jurisdiction of the federal courts, which are courts of limited jurisdiction,
may be difficult or impossible to obtain. A commercial dispute is unlikely to
present a federal question, and some courts have ruled that an Indian tribe as
a party is not a citizen of any state for purposes of establishing diversity
jurisdiction in the federal courts. State courts may also lack jurisdiction
over suits brought by non-Indians against Indian tribes in Connecticut. The
remedies available against an Indian tribe also depend, at least in part, upon
the rules of comity requiring initial exhaustion of remedies in tribal
tribunals and, as to some judicial remedies, the tribe's consent to
jurisdictional provisions contained in the disputed agreements. The United
States Supreme Court has held that where a tribal court exists, the
jurisdiction in that forum must first be exhausted before any dispute can be
properly heard by federal courts which would otherwise have jurisdiction. Where
a dispute as to the jurisdiction of the tribal forum exists, the tribal court
must first rule as to the limits of its own jurisdiction.
 
   In connection with the offering of the Outstanding Notes and the Exchange
Offers for the Exchange Notes, the Tribe has agreed, and has constitutionally
granted the Authority the power, to waive its sovereign immunity, and the
Authority has agreed to waive its sovereign immunity, for the limited purpose
of any suit by the Trustees under the Indentures or, as to the Authority, under
certain circumstances by the holders of the Exchange Notes to enforce repayment
of the Exchange Notes. The Tribe has also adopted a constitutional restraint
against any action by the Tribe or its officers which impairs contractual
obligations. If such waiver of
 
                                       68
<PAGE>
 
sovereign immunity is held to be ineffective, the Trustees and the Exchange
Note holders could be precluded from judicially enforcing their rights and
remedies against the Tribe or the Authority. If the waiver of the rule
requiring exhaustion of tribal remedies is held to be ineffective, the Trustees
and the Exchange Note holders could be subjected to substantial delay, cost and
expense while seeking such remedies in the Gaming Disputes Court or other
tribunals of the Tribe. In addition, unless the decisions of the Gaming
Disputes Court or other tribunals of the Tribe violate applicable state or
federal law, there might be no effective right to appeal such decisions in
state or federal court.
 
The Indian Gaming Regulatory Act of 1988
 
 Regulatory Authority
 
   The operation of casinos and of all gaming on Indian land is subject to the
Indian Gaming Regulatory Act of 1988. The Indian Gaming Regulatory Act (IGRA)
is administered by the National Indian Gaming Commission, an independent
agency, within the U.S. Department of Interior, exercising primary federal
regulatory responsibility over Indian gaming. The National Indian Gaming
Commission (NIGC) has exclusive authority to issue regulations governing tribal
gaming activities, approve tribal ordinances for regulating Class II and Class
III Gaming (as described below), approve management agreements for gaming
facilities, conduct investigations and generally monitor tribal gaming. Certain
responsibilities under IGRA (such as the approval of per capita distribution
plans to tribal members and the approval of transfer of lands into trust status
for gaming) are retained by the Bureau of Indian Affairs. The BIA also has
responsibility to review and approve land leases and other agreements relating
to Indian lands. Criminal enforcement is the exclusive responsibility of the
United States Department of Justice, except to the extent such enforcement
responsibility is shared with the State of Connecticut under the Mohegan
Compact and under the federal law that recognizes the Tribe.
 
   The NIGC is empowered to inspect and audit all Indian gaming facilities, to
conduct background checks on all persons associated with Class II Indian
gaming, to hold hearings, issue subpoenas, take depositions, adopt regulations
and assess fees and impose civil penalties for violations of IGRA. IGRA also
prohibits illegal gaming on Indian land and theft from Indian gaming
facilities. The NIGC has adopted rules implementing certain provisions of IGRA.
These rules govern, among other things, the submission and approval of tribal
gaming ordinances or resolutions and require an Indian tribe to have the sole
proprietary interest in and responsibility for the conduct of any gaming.
Tribes are required to issue gaming licenses only under articulated standards,
to conduct or commission financial audits of their gaming enterprises, to
perform or commission background investigations for primary management
officials and key employees, and to maintain their facilities in a manner that
adequately protects the environment and the public health and safety. These
rules also set out review and reporting procedures for tribal licensing of
gaming operation employees.
 
 Tribal Ordinances
 
   Under IGRA, except to the extent otherwise provided in a tribal-state
compact, Indian tribal governments have primary regulatory authority over Class
III Gaming on land within a tribe's jurisdiction. Therefore, the Authority's
gaming operations, and persons engaged in gaming activities, are guided by and
subject to the provisions of the Tribe's ordinances and regulations regarding
gaming.
 
   IGRA requires that the NIGC review tribal gaming ordinances and authorizes
the NIGC to approve such ordinances only if they meet certain requirements
relating to (1) the ownership, security, personnel background, recordkeeping,
and auditing of a tribe's gaming enterprises; (2) the use of the revenues from
such gaming; and (3) the protection of the environment and the public health
and safety. The Tribe adopted its gaming ordinance in July 1994, and the NIGC
approved the gaming ordinance in November 1994.
 
 Classes of Gaming
 
   IGRA classifies games that may be conducted on Indian lands into three
categories. "Class I Gaming" includes social games solely for prizes of minimal
value or traditional forms of Indian gaming engaged in by
 
                                       69
<PAGE>
 
individuals as part of, or in connection with, tribal ceremonies or
celebrations. "Class II Gaming" includes bingo, pulltabs, lotto, punch boards,
tip jars, certain non-banked card games (if such games are played legally
elsewhere in the state), instant bingo and certain other games similar to
bingo, if those games are played at the same location as bingo is played.
"Class III Gaming" includes all other forms of gaming, such as slot machines,
video casino games (e.g., video slots, video blackjack and video poker), so-
called "table games" (e.g., blackjack, craps, roulette) and other commercial
gaming (e.g., sports betting and pari-mutuel wagering).
 
   Class I Gaming on Indian lands is within the exclusive jurisdiction of the
Indian tribes and is not subject to IGRA. Class II Gaming is permitted on
Indian lands if (1) the state in which the Indian lands lie permits such gaming
for any purpose by any person, organization or entity; (2) the gaming is not
otherwise specifically prohibited on Indian lands by federal law; (3) the
gaming is conducted according to a tribal ordinance or resolution which has
been approved by the NIGC; (4) an Indian tribe has sole proprietary interest
and responsibility for the conduct of gaming; (5) the primary management
officials and key employees are tribally licensed; and (6) several other
requirements are met. Class III Gaming is permitted on Indian lands if the
conditions applicable to Class II Gaming are met and, in addition, the gaming
is conducted in conformance with the terms of a tribal-state Compact (a written
agreement between the tribal government and the government of the state within
whose boundaries the tribe's lands lie).
 
 Tribal-State Compacts
 
   IGRA requires states to negotiate in good faith with Indian tribes that seek
to enter into tribal-state compacts for the conduct of Class III Gaming. Such
tribal-state compacts may include provisions for the allocation of criminal and
civil jurisdiction between the state and the Indian tribe necessary for the
enforcement of such laws and regulations, taxation by the Indian tribe of
gaming activities in amounts comparable to those amounts assessed by the state
for comparable activities, remedies for breach of compacts, standards for the
operation of gaming and maintenance of the gaming facility, including
licensing, and any other subjects that are directly related to the operation of
gaming activities. While the terms of tribal-state compacts vary from state to
state, compacts within one state tend to be substantially similar. Tribal-state
compacts usually specify the types of permitted games, establish technical
standards for video gaming machines, set maximum and minimum machine payout
percentages, entitle the state to inspect casinos, require background
investigations and licensing of casino employees and may require the tribe to
pay a portion of the state's expenses for establishing and maintaining
regulatory agencies. Some tribal-state compacts are for set terms, while others
are for indefinite duration. The Mohegan Compact, approved by the Secretary of
the Interior in 1994, does not have a specific term and will remain in effect
until terminated by written agreement of both parties, or the provisions are
modified as a result of a change in applicable law.
 
   Tribal-state compacts have been the subject of litigation in a number of
states, including Alabama, California, Florida, Kansas, Michigan, Mississippi,
New Mexico, New York, Oklahoma, Oregon, South Dakota, Wisconsin and Washington.
Among the issues litigated have been the constitutionality of the provision of
IGRA which entitles tribes to sue in federal court to force states to negotiate
tribal-state compacts. Federal district courts in Alabama, Michigan and
Washington recently have held that the Eleventh Amendment to the United States
Constitution immunizes states from suit by Indian tribes in federal court
unless the state consents to such suit. Federal appellate courts have divided
over this issue. The United States Supreme Court recently held that the Indian
commerce clause of IGRA does not grant Congress authority to abrogate a state's
sovereign immunity. Accordingly, IGRA does not grant jurisdiction over a state
that did not consent to be sued.
 
   There has also been litigation challenging the authority of governors, under
state law, to enter into tribal-state compacts. Federal courts have upheld the
authority of the governors of Louisiana and Mississippi to enter into compacts,
while the highest state courts of New Mexico and Kansas have held that the
governors of those states did not have authority to enter into such compacts
without the consent or authorization of the legislatures of those states. In
the New Mexico and Kansas cases, the courts held that compacting is a
legislative function under the respective state constitutions. The court in the
New Mexico case also held that state law does not permit casino-style gaming.
 
                                       70
<PAGE>
 
   In Connecticut, there has been no litigation challenging the governor's
authority to enter into the Mohegan Compact. If such a suit were filed,
however, the Authority does not believe that the precedent in the New Mexico or
Kansas cases would apply. The Connecticut Attorney General has issued a formal
opinion that "existing [state] statutes provide the Governor with the authority
to negotiate and execute the.......... [Mohegan] Compact.'' The Attorney General
therefore declined to follow the Kansas case. In addition, the United States
Court of Appeals for the Second Circuit Court has held, in a case brought by
the Mashantucket Pequot Tribe, that Connecticut law authorizes casino gaming.
After execution of the Mohegan Compact, the Connecticut Legislature passed a
law requiring that future gaming compacts be approved by the legislature, but
that law does not apply to previously executed compacts such as the Mohegan
Compact.
 
   The Authority's operation of gaming is subject to the requirements and
restrictions contained in the Mohegan Compact. The Mohegan Compact authorizes
the Tribe to conduct most forms of Class III Gaming.
 
 Possible Changes in Federal Law
 
   Several bills have been introduced in Congress which would amend IGRA. While
there have been a number of technical amendments to the law, to date there have
been no material changes to the IGRA. Any amendment of IGRA could change the
governmental structure and requirements within which the Tribe could conduct
gaming.
 
BIA and NIGC Approvals
 
   Mohegan Sun is built on lands held in trust for the Tribe by the United
States of America, which are leased by the Tribe to the Authority. See "Other
Material Agreements--Land Lease from the Tribe to the Authority." Such lease,
and modifications or amendments to such lease, must be and have been approved
by the BIA. In addition, federal law requires that all contracts "by any person
with any tribe of Indians" which are "relative to their lands" must be approved
by the BIA. Federal courts can void agreements that have not been approved by
the BIA and grant full restitution of all amounts paid to the non-Indian party
by the tribe. BIA approved the Indentures and the Bank Credit Facility in
February, 1999 in connection with the closing of the offering of the
Outstanding Notes.
 
   Before the passage of IGRA, the BIA took the position that management
contracts for Indian gaming facilities did not require BIA approval.
Nevertheless, beginning in the early 1980s federal courts held that gaming
management contracts did require such approval, and several such agreements
were set aside by federal courts because they lacked approval. In 1988, with
the passage of IGRA, the approval of gaming management agreements and
collateral agreements between Indian tribes and gaming managers became the
province of the NIGC, but the BIA continues to have some residual jurisdiction.
The full scope of required review and approval for gaming management agreements
is not fully or precisely defined. The regulations and guidelines which the
NIGC and the BIA use to interpret their respective responsibilities are
incomplete and evolving. The federal law in this area has been the subject of
litigation and may be subject to further judicial or legislative
interpretation.

                       DESCRIPTION OF OTHER INDEBTEDNESS
 
Bank Credit Facility
 
   The Authority has a $425 million reducing, revolving, secured credit
facility with a syndicate of lenders led by Bank of America National Trust and
Savings Association ("Bank of America"). The Bank Credit Facility is currently
undrawn, with reductions to the total amounts available under the Bank Credit
Facility to begin on the earlier of March 31, 2002 or the end of the first
fiscal quarter after the completion date. In addition, the Authority has the
right, within two years following the closing of the Bank Credit Facility, to
arrange for increases in the Bank Credit Facility to an aggregate amount of
$500 million. The Authority will use the Bank Credit Facility for (1) the
Mohegan Sun expansion, (2) general working capital, and (3) general corporate
purposes of the Authority. The Bank Credit Facility is secured by, among other
things, a lien on substantially all of the Authority's assets. This
indebtedness is effectively senior in right of payment to the Exchange Notes.
The loan agreement subjects the Authority to a number of restrictive covenants
including financial covenants. These financial covenants relate to the
permitted maximums of the Authority's total debt and senior debt leverage
ratios, its minimum fixed charge coverage ratio, and maximum capital
expenditures. The Bank Credit Facility includes other affirmative and negative
covenants customarily found in loan agreements for similar transactions, many
of which will be similar to those included in the indenture for the Senior
Exchange Notes. Such covenants include provisions that:
 
  .  the Tribe preserve its existence as a federally recognized Indian Tribe;
 
  .  the Authority continually operate Mohegan Sun in compliance with all
     applicable laws;
 
  .  except under certain conditions, the Authority not sell or dispose of
     assets, incur other debt or contingent obligations, extend credit, make
     investments, or commingle its assets with other tribal assets of the
     Tribe; and
 
  .  permit a construction monitoring services group to inspect and review
     the proposed expansion and all budgets, plans, designs and
     specifications on a quarterly basis.
 
   At the Authority's option, interest will accrue on the basis of a base rate
formula or a Reserve Adjusted LIBOR based formula plus applicable spreads. The
base rate is the higher of the rate as publicly announced by Bank of America as
its "Reference Rate" or the Federal Funds Rate plus one-half of one percent per
annum. The Reserve Adjusted LIBOR Rate is the London Interbank Offered Rate for
one, two, three or six month dollar deposits as offered by Bank of America to
prime international banks in the offshore dollar market, adjusted for reserve
requirements. The Bank Credit Facility will terminate and all outstanding
amounts will become due on March 3, 2004.
 
Lines of Credit
 
   The Authority currently has a $2.5 million line of credit and letter of
credit arrangement with Fleet National Bank, an affiliate of Fleet Securities,
Inc. Borrowings are collateralized by a security interest in all of the
Authority's cash deposit accounts with Fleet National Bank. The line of credit
provides for interest based on various floating indexes. As of September 30,
1998, the Authority had outstanding letters of credit totalling $1.9 million
and had no other borrowings outstanding under the line of credit. No further
borrowings will be made under the line of credit. The first extension of credit
under the Bank Credit Facility, which will include the issuance of letters of
credit to replace the letters of credit outstanding under the line of credit.
The line of credit and the security interests collateralizing the line of
credit will be terminated at that time.
 
Equipment Financing
 
   The Authority currently has three agreements for equipment financing with
CIT Group/Equipment Financing, Inc. or its affiliates:
 
     (1) The Authority has $23.0 million of gaming equipment financing.
  Principal payments are over 48 months and commenced December 1996.
 
 
                                       72
<PAGE>
 
     (2) The Authority has a second agreement for equipment financing of $5.0
  million. Principal payments are over 48 months and commenced December 1996.
 
     (3) The Authority has a third agreement for equipment financing of an
  aggregate amount of $10.0 million. The principal payments are made over 48
  months from the commencement of each draw.
 
   The Authority has also received equipment financing of $4.0 million from
Phoenixcor, Inc. The principal payments are over 48 months and commenced
November 1996.
 
   The Authority received equipment financing of $3.0 million from Fleet
Capital Corporation, an affiliate of Fleet Securities, Inc. The principal
payments are over 48 months and commenced July 1997. As of September 30, 1997
this agreement has been assigned to KeyCorp Leasing.
 
   The Authority's equipment financing bears a weighted average interest of
9.1%. As of December 31, 1998, the future minimum lease payments, including
principal and interest, of the Authority's equipment financing are as follows
(in thousands):

Junior Subordinated Notes
 
   In conjunction with its initial opening of Mohegan Sun, the Authority
obtained a total of $90.0 million of subordinated financing from Sun
International Hotels Limited and Waterford Gaming L.L.C. including (1) $20.0
million of junior subordinated notes to each of Sun International Hotels
Limited and Waterford Gaming L.L.C., bearing interest at 15.0% per year, and
(2) $50.0 million of junior subordinated notes to Sun International Hotels
Limited evidencing draws made by the Authority under a secured completion
guarantee provided by Sun International Hotels Limited relating to the original
development of Mohegan Sun. Each junior subordinated note issued under the Sun
International Hotels Limited secured completion guarantee bears interest at the
rate per annum then most recently announced by Chase Manhattan Bank of New York
as its prime rate plus 1%, which shall be set and revised at intervals of six
months. The interest rates were 9.5% at both September 30, 1998 and September
30, 1997. Interest on junior subordinated notes is payable semi-annually.
Accrued and deferred interest payable on junior subordinated notes was $31.5
million and $17.9 million at September 30, 1998 and 1997, respectively. All
junior subordinated notes are due 2003 but may be redeemed at the Authority's
discretion commencing on January 1, 2000. During October 1998 and October 1997,
a total of $5.0 million of junior subordinated notes issued to Sun
International Hotels Limited pursuant to its secured completion guarantee were
purchased by Waterford Gaming L.L.C. from Sun International Hotels Limited.
 
   The Authority decided to redeem its junior subordinated notes on January 1,
2000. To accomplish this, the Authority effected a defeasance of the junior
subordinated notes on March 3, 1999. The Authority established a segregated
trust account with a defeasance agent with cash equivalent funds estimated to
be sufficient to permit a redemption of its junior subordinated notes on
January 1, 2000. All junior subordinated notes are currently held by Sun
International Hotels Limited, the parent company of a partner in Trading Cove
Associates, and Waterford Gaming L.L.C., also a partner in Trading Cove
Associates.

                       DESCRIPTION OF THE EXCHANGE NOTES
 
   The Authority issued the Outstanding Senior Notes under the Senior Notes
Indenture among itself, the Tribe and First Union National Bank, as trustee
(the "Senior Trustee"), and the Outstanding Senior Subordinated Notes under the
Senior Subordinated Notes Indenture among itself, the Tribe and State Street
Bank and Trust Company, as trustee (the "Senior Subordinated Trustee", and
together with the Senior Trustee, the "Trustees"). The terms of the Outstanding
Notes included and the terms of the Exchange Notes will be those stated in
their respective Indentures and those made part of the Indentures by reference
to the Trust Indenture Act of 1939.
 
   The terms of the Exchange Notes are identical in all material respects to
the Outstanding Notes, except that (1) the Exchange Notes will have been
registered under the Securities Act and therefore will not be subject to
certain restrictions on transfer applicable to the Outstanding Notes and (2)
Holders of the Exchange Notes will not be entitled to certain rights of Holders
of Outstanding Notes under the registration rights agreement. The terms of the
Exchange Notes include those stated in the Indentures and those made a part of
the Indentures by reference to the Trust Indenture Act of 1939 as in effect on
the date of the Indentures (the "Trust Indenture Act"). The Exchange Notes are
subject to all such terms, and Holders of the Exchange Notes are referred to
the Indentures and the Trust Indenture Act for a complete statement of such
terms. Copies of the Indentures are available from the Authority on request.
The statements and definitions of terms under this caption relating to the
Exchange Notes and the Indentures are summaries and do not purport to be
complete. Such summaries make use of certain terms defined in the Indentures
and are qualified in their entirety by express reference to the Indentures.
Certain terms used herein are defined below under "--Certain Definitions."
 
   The following description is a summary of the material provisions of the
Indentures and the registration rights agreements. It does not restate those
agreements in their entirety. We urge you to read the Indentures and the
registration rights agreements because they, and not this description, define
your rights as holders of the Notes. Copies of the forms of Indentures and
registration rights agreements are available from the Authority upon request.
You can find the definitions of certain terms used in this section under the
subheading
"--Certain Definitions." Reference is made to the Indentures for all of such
terms, as well as any other capitalized terms used herein for which no
definition is provided.
 
Description of the Senior Exchange Notes
 
 Ranking
 
   These Senior Exchange Notes
 
  .  are unsecured general obligations of the Authority;
 
  .  are effectively subordinated to up to $500 million of secured
     indebtedness under the Loan Agreement; and
 
  .  are senior in right of payment to all future subordinated Indebtedness
     of the Authority (including the Senior Subordinated Exchange Notes).
 
 Subsidiaries
 
   As of the date of the Senior Notes Indenture, the Authority will have no
Subsidiaries. However, the Senior Notes Indenture will permit the Authority to
create Subsidiaries and will generally require that these Subsidiaries be
designated as Restricted Subsidiaries (i.e., subject to the terms of the Senior
Notes Indenture) unless certain conditions are met. If these conditions are
met, the Authority will be permitted to designate a Subsidiary as an
Unrestricted Subsidiary, and Unrestricted Subsidiaries will not be subject to
many of the restrictive covenants of the Senior Notes Indenture.
 
 
                                       74
<PAGE>
 
 Principal, Maturity and Interest
 
   The Senior Exchange Notes will be limited to a maximum aggregate principal
amount of $200 million. The Authority will issue Senior Exchange Notes without
coupons and in fully registered form only, in minimum denominations of $1,000
and integral multiples of $1,000. The Senior Exchange Notes will mature on
January 1, 2006.
 
   Interest on the Senior Exchange Notes will accrue at the rate of 8 1/8% per
annum and will be payable semi-annually in arrears on January 1 and July 1,
beginning on July 1, 1999. The Authority will make each interest payment to the
holders of record of these Senior Exchange Notes on the immediately preceding
December 15 and June 15.
 
   Interest on the Senior Exchange Notes will accrue from the date of original
issuance or, if interest has already been paid, from the date it was most
recently paid. Interest will be computed on the basis of a 360-day year
comprised of twelve 30-day months.
 
 Optional Redemption
 
   Except as otherwise shown in this section, the Authority will not have the
right to redeem the Senior Exchange Notes.
 
   If, at any time after the Issue Date, any Gaming Regulatory Authority
requires a holder to be licensed or otherwise qualified under applicable gaming
laws in order for the Authority to maintain any of its gaming licenses or
franchises and the holder does not obtain such license or qualification within
the time periods described in the Senior Notes Indenture and at its own cost
and expense, then the Authority will have the right to either
 
  .  require the holder to dispose of its Senior Exchange Notes within the
     time period specified by the Gaming Regulatory Authority or 30 days,
     whichever is shorter; or
 
  .  redeem the holder's Senior Exchange Notes at a price equal to the lesser
     of (1) the principal amount of the Senior Exchange Notes held by the
     holder, (2) the price paid for the Senior Exchange Notes by the holder,
     and (3) the current market price of the Senior Exchange Notes, in each
     case, including all accrued and unpaid interest and Additional Interest,
     if any, to the redemption date or the date a finding of unsuitability is
     made by the applicable Gaming Regulatory Authority, if earlier.
 
   The Authority will comply with the redemption procedures for the Senior
Exchange Notes described in the Senior Notes Indenture unless otherwise
required by a Gaming Regulatory Authority. In addition, the Authority may
redeem all or a part of these Senior Exchange Notes upon not less than 30 nor
more than 60 days' notice, at a redemption price (expressed as percentages of
principal amount) equal to 100% of the principal amount thereof plus the
Applicable Premium, if any, plus accrued and unpaid interest thereon, if any,
to the applicable redemption date.
 
   The "Applicable Premium" of any redeemed Senior Note equals the excess of
 
     (a) the present value at the date of redemption of 100% of the principal
  amount of such Senior Exchange Note plus all required interest payments due
  on such Senior Exchange Note through its Stated Maturity date (excluding
  accrued but unpaid interest), calculated using a discount rate equal to the
  Treasury Rate plus 50 basis points over
 
     (b) the principal amount of such Senior Exchange Note, if greater.
 
   If the period from the date of redemption to the Stated Maturity date is
greater than one year, the "Treasury Rate" will be equal to the yield to
maturity as of such date of redemption of United States Treasury securities
with a constant maturity (as complied and published in the most recent Federal
Reserve Statistical Release H.15 (519) that became publicly available at least
two business days prior to the date of redemption (or, if the Federal Reserve
Statistical Release H.15 (519) is no longer published, any publicly available
source of similar market data)) most nearly equal to the period from the date
of redemption to the Stated Maturity date.
 
                                       75
<PAGE>
 
   If the period from the date of redemption to the Stated Maturity date is
less than one year, the "Treasury Rate" will be equal to the weekly average
yield on actually traded United States Treasury securities adjusted to a
constant maturity of one year.
 
 Selection and Notice
 
   If less than all of the Senior Exchange Notes are to be redeemed at any
time, the Senior Trustee will select Senior Exchange Notes for redemption as
follows:
 
     (1) if the Senior Exchange Notes are listed, in compliance with the
  requirements of the principal national securities exchange on which the
  Senior Exchange Notes are listed; or
 
     (2) if the Senior Exchange Notes are not so listed, on a pro rata basis,
  by lot or by such method as the Senior Trustee shall deem fair and
  appropriate.
 
   No Senior Exchange Notes of $1,000 or less shall be redeemed in part.
Notices of redemption shall be mailed by first class mail at least 30 but not
more than 60 days before the redemption date to each holder of Senior Exchange
Notes to be redeemed at its registered address. Notices of redemption may not
be conditional.
 
   If any Senior Exchange Note is to be redeemed in part only, the notice of
redemption that relates to that Senior Exchange Note shall state the portion of
the principal amount thereof to be redeemed. A new Senior Note in principal
amount equal to the unredeemed portion of the original Senior Exchange Note
will be issued in the name of the holder thereof upon cancellation of the
original Senior Exchange Note. Senior Exchange Notes called for redemption
become due on the date fixed for redemption. On and after the redemption date,
interest ceases to accrue on Senior Exchange Notes or portions of them called
for redemption.
 
 Repurchase at the Option of Holders
 
  Change of Control
 
   If a Change of Control occurs, each holder of the Senior Exchange Notes will
have the right to require the Authority to repurchase all or any part (equal to
$1,000 or an integral multiple thereof) of that holder's Senior Exchange Notes
pursuant to a Change of Control Offer. In the Change of Control Offer, the
Authority will offer a Change of Control Payment in cash equal to 101% of the
aggregate principal amount of Senior Exchange Notes repurchased plus accrued
and unpaid interest and Additional Interest, if any, thereon, to the date of
purchase.
 
   Within 20 business days following any Change of Control, the Authority will
mail a notice to each holder describing the transaction or transactions that
constitute the Change of Control and offering to repurchase Senior Exchange
Notes on the Change of Control Payment Date specified in such notice, pursuant
to the procedures required by the Senior Notes Indenture and described in such
notice. The Authority will comply with the requirements of Rule 14e-1 under the
Exchange Act and any other securities laws and regulations thereunder to the
extent such laws and regulations are applicable in connection with the
repurchase of the Senior Exchange Notes as a result of a Change of Control.
 
   On the Change of Control Payment Date, the Authority will, to the extent
lawful
 
     (1) accept for payment all Senior Exchange Notes or portions thereof
  properly tendered pursuant to the Change of Control Offer;
 
     (2) deposit with the Paying Agent an amount equal to the Change of
  Control Payment in respect of all Senior Exchange Notes or portions thereof
  so tendered; and
 
     (3) deliver or cause to be delivered to the Senior Trustee the Senior
  Exchange Notes so accepted together with an Officers' Certificate stating
  the aggregate principal amount of Senior Exchange Notes or portions thereof
  being purchased by the Authority.
 
                                       76
<PAGE>
 
   The Paying Agent will promptly mail to each holder of Senior Exchange Notes
so tendered the Change of Control Payment for such Senior Exchange Notes, and
the Senior Trustee will promptly authenticate and mail (or cause to be
transferred by book entry) to each holder a new Senior Exchange Note equal in
principal amount to any unpurchased portion of the Senior Exchange Notes
surrendered, if any; provided that each such new Senior Exchange Note will be
in a principal amount of $1,000 or an integral multiple thereof. The Authority
will notify the Senior Trustee and will instruct the Senior Trustee to notify
the holders of the results of the Change of Control Offer on or as soon as
practicable after the Change of Control Payment Date.
 
   Except as described above with respect to a Change of Control, the Senior
Notes Indenture does not contain provisions that permit the holders of the
Senior Exchange Notes to require that the Authority repurchase or redeem the
Senior Exchange Notes in the event of a takeover, recapitalization or similar
transaction.
 
   The Loan Agreement will prohibit the Authority from purchasing any Senior
Exchange Notes and also will provide that certain change of control events with
respect to the Authority will constitute a default under the Loan Agreement.
Any future credit agreements or other agreements relating to secured
indebtedness to which the Authority becomes a party may contain similar
restrictions and provisions. In the event a Change of Control occurs at a time
when the Authority is prohibited from purchasing Senior Exchange Notes, the
Authority could seek the consent of its lenders to the purchase of Senior
Exchange Notes or could attempt to refinance the borrowings that contain such
prohibition. If the Authority does not obtain such a consent or repay such
borrowings, the Authority will remain prohibited from purchasing Senior
Exchange Notes. In such case, the Authority's failure to purchase tendered
Senior Exchange Notes would constitute an Event of Default under the Senior
Notes Indenture which would, in turn, constitute a default under the Loan
Agreement.
 
   The Authority will not be required to make a Change of Control Offer upon a
Change of Control if a third party makes the Change of Control Offer in the
manner, at the times and otherwise in compliance with the requirements shown in
the Senior Notes Indenture applicable to a Change of Control Offer made by the
Authority and purchases all Senior Exchange Notes validly tendered and not
withdrawn under such Change of Control Offer.
 
  Asset Sales
 
   The Authority will not, and will not permit any of its Restricted
Subsidiaries to, consummate an Asset Sale unless
 
     (1) the Authority (or its Restricted Subsidiary, as the case may be)
  receives consideration at the time of such Asset Sale at least equal to the
  fair market value (as determined in good faith by the Management Board and
  evidenced by a resolution shown in an Officers' Certificate delivered to
  the Senior Trustee) of the assets sold or otherwise disposed of; and
 
     (2) except in the case of a Permitted Asset Swap, at least 75% of the
  consideration therefor received by the Authority or such Restricted
  Subsidiary is in the form of cash. For purposes of this provision, each of
  the following shall be deemed to be cash:
 
       (a) any liabilities that would appear on the Authority's or such
    Restricted Subsidiary's balance sheet prepared according to GAAP (other
    than contingent liabilities and liabilities that are by their terms
    subordinated to the Senior Exchange Notes or any guarantee thereof)
    that are assumed by the transferee of any such assets pursuant to a
    customary novation agreement that releases the Authority or such
    Restricted Subsidiary from further liability; and
 
       (b) any securities, notes or other obligations received by the
    Authority or any such Restricted Subsidiary from such transferee that
    are converted by the Authority or such Restricted Subsidiary into cash
    (to the extent of the cash received) within 30 days of the receipt
    thereof,
 
provided, however, that the Authority will not be permitted to make any Asset
Sale of Key Project Assets.
 
                                       77
<PAGE>
 
   Within 360 days after the receipt of any Net Proceeds from an Asset Sale,
the Authority may apply such Net Proceeds, at its option, to:
 
     (1) repay permanently term Indebtedness under Credit Facilities of the
  Authority or any Restricted Subsidiary;
 
     (2) repay revolving credit Indebtedness under Credit Facilities and
  correspondingly permanently reduce commitments with respect thereto;
 
     (3) acquire a majority of the assets of, or a majority of the Voting
  Stock of, an entity engaged in the Principal Business or a Related
  Business;
 
     (4) make capital expenditures or acquire other long-term assets that are
  used or useful in the Principal Business or a Related Business;
 
     (5) make an investment in the Principal Business or a Related Business
  or in tangible long-term assets used or useful in the Principal Business or
  a Related Business; or
 
     (6) reduce permanently Indebtedness that is not Subordinated
  Indebtedness.
 
   Pending the final application of any such Net Proceeds, the Authority may
temporarily reduce revolving credit borrowings or otherwise invest such Net
Proceeds in any manner that is not prohibited by the Senior Notes Indenture.
 
   Any Net Proceeds from Asset Sales that are not applied or invested as
provided in the preceding paragraph will be deemed to constitute "Excess
Proceeds." When the aggregate amount of Excess Proceeds exceeds $15.0 million,
the Authority will make an Asset Sale Offer to all holders of Senior Exchange
Notes and all holders of other Indebtedness containing provisions similar to
those shown in the Senior Notes Indenture with respect to offers to purchase or
redeem with the proceeds of sales of assets to purchase the maximum principal
amount of Senior Exchange Notes and such other Indebtedness that may be
purchased out of the Excess Proceeds. The offer price in any Asset Sale Offer
will be equal to 100% of the principal amount plus accrued and unpaid interest
and Additional Interest, if any, to the date of purchase and will be payable in
cash, according to the procedures shown in the Senior Notes Indenture and such
other Indebtedness. To the extent that any Excess Proceeds remain after
consummation of an Asset Sale Offer, the Authority may use such Excess Proceeds
for any purpose not otherwise prohibited by the Senior Notes Indenture. If the
aggregate principal amount of Senior Exchange Notes and such other Indebtedness
tendered into such Asset Sale Offer surrendered by holders thereof exceeds the
amount of Excess Proceeds, the Senior Trustee shall select the Senior Exchange
Notes and such other Indebtedness (to the extent that such other Indebtedness
permits such selection) to be purchased on a pro rata basis. Upon completion of
such offer to purchase, the amount of Excess Proceeds shall be reset at zero.
 
 Certain Covenants
 
  Restricted Payments
 
   The Authority will not, and the Authority will not permit any of its
Restricted Subsidiaries, directly or indirectly, to
 
     (1) make any payment on or with respect to any of the Authority's or any
  of its Restricted Subsidiaries' Equity Interests;
 
     (2) purchase, redeem, defease or otherwise acquire or retire for value
  any Equity Interest in the Authority held by the Tribe or any Affiliate of
  the Tribe;
 
     (3) make any payment on or with respect to, or purchase, redeem, defease
  or otherwise acquire or retire for value any Subordinated Indebtedness
  (other than the defeasance and ultimate redemption of the junior
  subordinated notes according to their terms and the terms of the Defeasance
  Trust), except a payment of interest or principal at Stated Maturity
  thereof;
 
                                       78
<PAGE>
 
     (4) make any payment or distribution to the Tribe (or any other agency,
  instrumentality or political subunit thereof) or make any general
  distribution to the members of the Tribe (other than Government Service
  Payments); or
 
     (5) make any Restricted Investment;
 
(all such payments and other actions shown in clauses (1) through (5) above are
collectively referred to as "Restricted Payments") unless, at the time of and
after giving effect to such Restricted Payment
 
     (A) no Default or Event of Default shall have occurred and be continuing
  or would occur as a consequence thereof;
 
     (B) the Authority would, at the time of such Restricted Payment and
  after giving pro forma effect thereto as if such Restricted Payment had
  been made at the beginning of the applicable four-quarter period, have been
  permitted to incur at least $1.00 of additional Indebtedness pursuant to
  the Fixed Charge Coverage Ratio test shown in the first paragraph of the
  covenant described below under the caption "--Incurrence of Indebtedness
  and Issuance of Preferred Stock"; and
 
     (C) such Restricted Payment, together with the aggregate amount of all
  other Restricted Payments made by the Authority and its Restricted
  Subsidiaries after the date of the Senior Notes Indenture (excluding
  Restricted Payments permitted by clauses (2), (3), (4) and (5) of the next
  succeeding paragraph), is less than the sum, without duplication, of
 
       (i) 50% of the Consolidated Net Income of the Authority for the
    period (taken as one accounting period) from the beginning of the first
    fiscal quarter commencing after the date of the Senior Notes Indenture
    to the end of the Authority's most recently ended fiscal quarter for
    which internal financial statements are available at the time of such
    Restricted Payment (or, if such Consolidated Net Income for such period
    is a deficit, less 100% of such deficit), plus (ii) 100% of the
    aggregate net cash proceeds or fair market value (as determined in good
    faith by the Management Board and evidenced by a resolution shown in an
    Officers' Certificate delivered to the Senior Trustee) of assets or
    property (other than cash) received by the Authority from capital
    contributions from the Tribe that bear no mandatory obligation to repay
    the Tribe and other than from a Restricted Subsidiary of the Authority,
    plus (iii) to the extent that any Restricted Investment that was made
    after the date of the Senior Notes Indenture is sold, liquidated or
    otherwise disposed of for cash or an amount equal to the fair market
    value thereof (as determined in good faith by the Management Board and
    evidenced by a resolution shown in an Officers' Certificate delivered
    to the Senior Trustee), the lesser of (a) the cash return of capital or
    fair market value amount, as the case may be, with respect to such
    Restricted Investment (less the cost of disposition, if any) and (b)
    the initial amount of such Restricted Investment, plus (iv) to the
    extent that any Unrestricted Subsidiary is redesignated as a Restricted
    Subsidiary after the date of the Senior Notes Indenture, the lesser of
    (a) the fair market value of the Authority's Investment in such
    Subsidiary as of the date of such redesignation or (b) such fair market
    value as of the date on which such Subsidiary was originally designated
    as an Unrestricted Subsidiary.
 
   So long as no Default has occurred and is continuing or would be caused
thereby, the preceding provisions will not prohibit
 
     (1) the defeasance, redemption, repurchase or other acquisition of
  Subordinated Indebtedness with the net cash proceeds from an incurrence of
  Permitted Refinancing Indebtedness;
 
     (2) the payment of any dividend by a Restricted Subsidiary of the
  Authority to the holders of its common Equity Interests on a pro rata
  basis;
 
     (3) the repurchase, redemption or other acquisition or retirement for
  value of any Equity Interests of any Restricted Subsidiary of the Authority
  held by any member of the Authority's (or any of its Restricted
  Subsidiaries') management pursuant to any management equity subscription
  agreement or stock option agreement in effect as of the date of the Senior
  Notes Indenture; provided that (a) the aggregate price paid
 
                                       79
<PAGE>
 
  for all such repurchased, redeemed, acquired or retired Equity Interests
  shall not exceed $1.0 million in any 12-month period and (b) the aggregate
  amount of all such repurchased, redeemed, acquired or retired Equity
  Interests shall not in the aggregate exceed $3.0 million;
 
     (4) the redemption or purchase of Subordinated Indebtedness of the
  Authority if the holder of such Subordinated Indebtedness has failed to
  qualify or be found suitable or otherwise be eligible by any Gaming
  Regulatory Authority to remain a holder of such Subordinated Indebtedness;
 
     (5) the redemption, defeasance, repurchase or other acquisition or
  retirement of Subordinated Indebtedness with the net cash proceeds from a
  substantially concurrent capital contribution from the Tribe (provided that
  such capital contribution is not counted for purposes of clause (C)(ii)
  above); and
 
     (6) any other Restricted Payments in an amount not to exceed $20.0
  million at any one time outstanding.
 
   The Authority may designate any Restricted Subsidiary to be an Unrestricted
Subsidiary if such designation would not cause a Default; provided that in no
event shall (i) any entity (including any Subsidiary of the Authority or the
Authority or any operating division thereof) engaged in a Principal Business be
transferred to or held by an Unrestricted Subsidiary or (ii) any Key Project
Assets or Gaming Licenses be transferred to an Unrestricted Subsidiary. In the
event of such designation, all outstanding Investments owned by the Authority
and its Restricted Subsidiaries in the Subsidiary so designated will be deemed
to be an Investment made as of the time of such designation and will reduce the
amount available for Restricted Payments under the first paragraph of this
covenant unless the Investment constitutes a Permitted Investment. All such
outstanding Investments will be deemed to constitute Restricted Payments in an
amount equal to the fair market value of such Investments at the time of such
designation. Such designation will only be permitted if such Restricted Payment
would be permitted at such time and if such Restricted Subsidiary otherwise
meets the definition of an Unrestricted Subsidiary. The Authority may
redesignate an Unrestricted Subsidiary to be a Restricted Subsidiary if such
redesignation would not otherwise cause a Default.
 
   The amount of all Restricted Payments (other than cash) shall be the fair
market value on the date of the Restricted Payment of the asset(s) or
securities proposed to be transferred or issued by the Authority or such
Restricted Subsidiary, as the case may be, pursuant to the Restricted Payment.
The fair market value of any assets or securities that are required to be
valued by this covenant shall be determined by the Management Board whose
resolution with respect thereto shall be delivered to the Senior Trustee. Not
later than the date of making any Restricted Payment, the Authority shall
deliver to the Senior Trustee an Officers' Certificate stating that such
Restricted Payment is permitted and setting forth the basis upon which the
calculations required by the covenant "--Restricted Payments" were computed.
 
  Subordination of Junior Payments Under the Relinquishment Agreement
 
   All Obligations under the Senior Exchange Notes shall be "Senior
Obligations" as defined in the Relinquishment Agreement and will not be on
parity with, or subordinated in right of payment to, the Junior Relinquishment
Payments (as defined in the Relinquishment Agreement) and the Authority will
not amend Section 6.2 of the Relinquishment Agreement in a manner adverse to
the holders of the Senior Exchange Notes.
 
  Incurrence of Indebtedness and Issuance of Preferred Stock
 
   The Authority will not, and will not permit any of its Subsidiaries to,
directly or indirectly, create, incur, issue, assume, guarantee or otherwise
become directly or indirectly liable, contingently or otherwise, with respect
to (collectively, "incur") any Indebtedness (including Acquired Indebtedness)
and the Authority will not issue any Disqualified Stock and will not permit any
of its Subsidiaries to issue any shares of preferred stock; provided, however,
that the Authority may incur Indebtedness (including Acquired Indebtedness) or
issue shares of Disqualified Stock and the Authority's Subsidiaries may incur
Indebtedness or issue preferred stock if the Fixed Charge Coverage Ratio for
the Authority's most recently ended four full fiscal quarters for which
 
                                       80
<PAGE>
 
internal financial statements are available immediately preceding the date on
which such additional Indebtedness is incurred would have been at least 2.0 to
1 if such Indebtedness is incurred before September 30, 2001 and 2.5 to 1 if
such indebtedness is incurred thereafter, determined on a pro forma basis
(including a pro forma application of the net proceeds therefrom), as if the
additional Indebtedness had been incurred at the beginning of such four-quarter
period. Notwithstanding the foregoing, the Authority will not issue any
Disqualified Stock or any type of Capital Stock that would violate IGRA.
 
   So long as no Default or Event of Default shall have occurred and be
continuing, or would be caused thereby, the first paragraph of this covenant
will not prohibit the incurrence of any of the following items of Indebtedness:
 
     (1) the incurrence by the Authority or its Restricted Subsidiaries of
  Indebtedness and letters of credit pursuant to Credit Facilities; provided
  that the aggregate principal amount of all such Indebtedness and letters of
  credit outstanding under all Credit Facilities, after giving effect to such
  incurrence (with letters of credit being deemed to have a principal amount
  equal to the maximum potential liability of the Authority thereunder), does
  not exceed $500 million less the aggregate amount of all Net Proceeds of
  Asset Sales applied by the Authority or any of its Restricted Subsidiaries
  since the date of the Senior Notes Indenture to repay Indebtedness under
  Credit Facilities pursuant to the covenant described above under the
  caption "--Repurchase at the Option of Holders--Asset Sales";
 
     (2) the incurrence by the Authority and its Restricted Subsidiaries of
  the Existing Indebtedness;
 
     (3) the incurrence by the Authority of Indebtedness represented by the
  Senior Exchange Notes and the Senior Exchange Notes;
 
     (4) the incurrence by the Authority of Indebtedness represented by the
  Senior Subordinated Exchange Notes and the Senior Subordinated Exchange
  Notes;
 
     (5) the incurrence by the Authority or any of its Restricted
  Subsidiaries of Indebtedness represented by Capital Lease Obligations,
  mortgage financings or purchase money obligations, in each case incurred
  for the purpose of financing all or any part of the purchase price of
  furniture, fixtures, equipment or similar assets used or useful in the
  business of the Authority or such Restricted Subsidiary not to exceed 100%
  of the lesser of cost or fair market value of the assets financed and, in
  an aggregate principal amount under this clause not to exceed $25.0 million
  at any time outstanding;
 
     (6) the incurrence by the Authority or any of its Restricted
  Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the
  net proceeds of which are used to refund, refinance, renew, extend, defease
  or replace Indebtedness that was permitted by the Senior Notes Indenture to
  be incurred under the first paragraph of this covenant or clauses (1), (2)
  (other than the junior subordinated notes), (3), (4) or (5) of this
  paragraph;
 
     (7) the incurrence by the Authority or any of its Restricted
  Subsidiaries of Hedging Obligations that are incurred for the purpose of
  fixing or hedging interest rate risk with respect to any floating rate
  Indebtedness that is permitted by the terms of the Senior Notes Indenture
  to be outstanding;
 
     (8) the guarantee by the Authority or any of its Restricted Subsidiaries
  of any Indebtedness of the Authority or any of its Restricted Subsidiaries
  that was permitted to be incurred by another provision of this covenant;
 
     (9)  the incurrence by a Wholly Owned Restricted Subsidiary of
  Indebtedness owed to another Wholly Owned Restricted Subsidiary or to the
  Authority; provided that if at any time any such Wholly Owned Restricted
  Subsidiary ceases to be a Wholly Owned Restricted Subsidiary, any such
  Indebtedness shall be deemed to be an incurrence of Indebtedness for the
  purposes of this covenant;
 
     (10) the incurrence by the Authority or any of its Restricted
  Subsidiaries of additional Indebtedness in an aggregate principal amount
  (or accreted value, as applicable) at any time outstanding, including all
  Permitted Refinancing Indebtedness incurred to refund, refinance or replace
  any Indebtedness incurred pursuant to this clause (10), not to exceed $25.0
  million; or
 
                                       81
<PAGE>
 
     (11) the incurrence by the Authority's Unrestricted Subsidiaries of Non-
  Recourse Debt, provided, however, that if any such Indebtedness ceases to
  be Non-Recourse Debt of an Unrestricted Subsidiary, such event shall be
  deemed to constitute an incurrence of Indebtedness by a Restricted
  Subsidiary of the Authority that was not permitted by this clause (11).
 
   For purposes of determining compliance with this "--Incurrence of
Indebtedness and Issuance of Preferred Stock" covenant, if an item of proposed
Indebtedness meets the criteria of more than one of the categories of Permitted
Indebtedness described in clauses (1) through (11) above or is entitled to be
incurred pursuant to the first paragraph of this covenant, the Authority shall,
in its sole discretion, classify such item of Indebtedness on the date of its
incurrence in any manner that complies with this covenant.
 
  Limitation on Issuances and Sales of Equity Interests in Wholly Owned
 Restricted Subsidiaries
 
   The Authority (i) will not, and will not permit any Wholly Owned Restricted
Subsidiary of the Authority to, transfer, convey, sell, lease or otherwise
dispose of any Equity Interests in any Wholly Owned Restricted Subsidiary of
the Authority to any Person (other than the Authority or another Wholly Owned
Restricted Subsidiary of the Authority), unless (a) such transfer, conveyance,
sale, lease or other disposition is of all the Equity Interests in such Wholly
Owned Restricted Subsidiary and (b) the cash Net Proceeds from such transfer,
conveyance, sale, lease or other disposition are applied according to the
covenant described above under the caption "--Repurchase at the Option of
Holders--Asset Sales," and (ii) will not permit any Wholly Owned Restricted
Subsidiary of the Authority to issue any of its Equity Interests (other than,
if necessary, shares of its Capital Stock constituting directors' qualifying
shares) to any Person other than to the Authority or a Wholly Owned Restricted
Subsidiary of the Authority.
 
  Liens
 
   The Senior Notes Indenture will provide that the Authority will not, and
will not permit any of its Restricted Subsidiaries to, directly or indirectly,
create, incur, assume or otherwise cause or suffer to exist or become effective
any Lien of any kind (other than Permitted Liens) upon any of its property or
assets, now owned or hereafter acquired, unless all payments due under the
Senior Notes Indenture and the Senior Exchange Notes are secured on an equal
and ratable basis with the obligations so secured until such time as such
obligations are no longer secured by a Lien.
 
  Dividend and Other Payment Restrictions Affecting Restricted Subsidiaries
 
   The Authority will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, create or permit to exist or become
effective any encumbrance or restriction on the ability of any Restricted
Subsidiary to
 
     (1) pay dividends or make any other distributions on its Capital Stock
  to the Authority or any of the Authority's Restricted Subsidiaries, or with
  respect to any other interest or participation in, or measured by, its
  profits, or pay any indebtedness owed to the Authority or any of the
  Authority's Restricted Subsidiaries;
 
     (2) make loans or advances to the Authority or any of the Authority's
  Restricted Subsidiaries; or
 
     (3) transfer any of its properties or assets to the Authority or any of
  the Authority's Restricted Subsidiaries.
 
   However, the preceding restrictions will not apply to encumbrances or
restrictions existing under or by reason of
 
     (1) Existing Indebtedness as in effect on the date of the Senior Notes
  Indenture and any amendments, modifications, restatements, renewals,
  extensions, increases, supplements, refundings, replacements or
  refinancings thereof, provided that such amendments, modifications,
  restatements, renewals, extensions,
 
                                       82
<PAGE>
 
  increases, supplements, refundings, replacements or refinancings are no
  more restrictive, taken as a whole, with respect to such dividend and other
  payment restrictions than those contained in such Existing Indebtedness, as
  in effect on the date of the Senior Notes Indenture;
 
     (2) the Senior Notes Indenture and the Senior Exchange Notes;
 
     (3) the Senior Subordinated Notes Indenture and the Senior Subordinated
  Exchange Notes;
 
     (4) the Credit Facilities;
 
     (5) applicable law;
 
     (6) any instrument governing Indebtedness or Capital Stock of a Person
  acquired by the Authority or any of its Restricted Subsidiaries as in
  effect at the time of such acquisition (except to the extent such
  Indebtedness was incurred in connection with or in contemplation of such
  acquisition), which encumbrance or restriction is not applicable to any
  Person, or the properties or assets of any Person, other than the Person,
  or the property or assets of the Person, so acquired, provided that, in the
  case of Indebtedness, such Indebtedness was permitted by the terms of the
  Senior Notes Indenture to be incurred;
 
     (7) customary non-assignment provisions in leases or other contracts
  entered into in the ordinary course of business and consistent with past
  practices;
 
     (8) purchase money obligations (including, without limitation, Capital
  Lease Obligations) for property acquired in the ordinary course of business
  that impose restrictions on the property so acquired of the nature
  described in clause (3) of the preceding paragraph;
 
     (9) any agreement for the sale or other disposition of a Restricted
  Subsidiary that restricts distributions by such Restricted Subsidiary
  pending its sale or other disposition;
 
     (10) Permitted Refinancing Indebtedness, provided that the restrictions
  contained in the agreements governing such Permitted Refinancing
  Indebtedness are no more restrictive, taken as a whole, than those
  contained in the agreements governing the Indebtedness being refinanced;
 
     (11) Liens securing Indebtedness otherwise permitted to be incurred
  pursuant to the provisions of the covenant described above under the
  caption "--Liens" that limit the right of the Authority or any of its
  Restricted Subsidiaries to dispose of the assets subject to such Lien;
 
     (12) provisions with respect to the disposition or distribution of
  assets or property in joint venture agreements and other similar agreements
  entered into in the ordinary course of business; and
 
     (13) restrictions on cash or other deposits or net worth imposed by
  customers under contracts entered into in the ordinary course of business.
 
  Transactions with Affiliates
 
   The Authority will not, and the Authority will not permit any of its
Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or
otherwise dispose of any of its properties or assets to, or purchase any
property or assets from, or enter into or make or amend any transaction,
contract, agreement, understanding, loan, advance or guarantee with, or for the
benefit of, any Affiliate (each of the foregoing, an "Affiliate Transaction"),
unless
 
     (1) such Affiliate Transaction is on terms that are no less favorable to
  the Authority or the relevant Restricted Subsidiary than those that would
  have been obtained in a comparable transaction by the Authority or such
  Restricted Subsidiary with an unrelated Person; and
 
     (2) the Authority delivers to the Senior Trustee:
 
       (a) with respect to any Affiliate Transaction or series of related
    Affiliate Transactions involving aggregate consideration in excess of
    $5.0 million, a resolution of the Management Board shown in an
    Officers' Certificate certifying that such Affiliate Transaction
    complies with this covenant and that such Affiliate Transaction has
    been approved by a majority of the disinterested members of the
    Management Board; and
 
                                       83
<PAGE>
 
       (b) with respect to any Affiliate Transaction or series of related
    Affiliate Transactions involving aggregate consideration in excess of
    $10.0 million, an opinion as to the fairness to the Authority or such
    Restricted Subsidiary of such Affiliate Transaction from a financial
    point of view issued by an accounting, appraisal or investment banking
    firm of national standing.
 
   The following items shall not be deemed to be Affiliate Transactions and,
therefore, will not be subject to the provisions of the prior paragraphs:
 
     (1) any employment agreement or arrangement entered into by the
  Authority or any of its Restricted Subsidiaries in the ordinary course of
  business and consistent with the past practice of the Authority or such
  Restricted Subsidiary;
 
     (2) transactions between or among the Authority and/or its Restricted
  Subsidiaries;
 
     (3) payment of reasonable Management Board fees to members of the
  Management Board;
 
     (4) transactions with Persons in whom the Authority owns any Equity
  Interests, so long as the remaining equity holders of such Person are not
  Affiliates of the Authority or any of its Subsidiaries;
 
     (5) Government Service Payments;
 
     (6) transactions pursuant to the Development Services Agreement, the
  Relinquishment Agreement and the Side Letters;
 
     (7) Restricted Payments or Permitted Investments that are made in
  compliance with the provisions of the Senior Notes Indenture described
  above under the caption "--Restricted Payments;" and
 
     (8) contractual arrangements existing on the date of the Senior Notes
  Indenture and any renewals, extensions and modifications thereof that are
  not materially adverse to holders.
 
  Subsidiary Guarantees
 
   The Senior Notes Indenture provides that if the Authority acquires or
creates any Restricted Subsidiary after the date of the Senior Notes Indenture,
then that newly acquired or created Restricted Subsidiary must become a
Subsidiary Guarantor and execute a supplemental indenture satisfactory to the
Senior Trustee and deliver an Opinion of Counsel to the Senior Trustee within
20 business days of the date on which it is acquired or created.
 
   The obligations of each Subsidiary Guarantor under its Senior Subsidiary
Guarantee will be limited so as not to constitute a fraudulent conveyance under
applicable law.
 
   No Subsidiary Guarantor may consolidate with or merge with or into (whether
or not such Subsidiary Guarantor is the surviving Person), another corporation,
Person or entity whether or not affiliated with such Subsidiary Guarantor
unless: (i) subject to the provisions of the following paragraph, the Person
formed by or surviving any such consolidation or merger (if other than such
Subsidiary Guarantor) assumes all the obligations of such Subsidiary Guarantor
pursuant to a supplemental indenture in form and substance reasonably
satisfactory to the Senior Trustee; and (ii) immediately after giving effect to
such transaction, no Default or Event of Default exists.
 
   The Senior Notes Indenture will permit the merger of one or more Subsidiary
Guarantors with or into another Subsidiary Guarantor or with or into the
Authority; provided that in the case of a merger with or into the Authority,
the Authority is the surviving entity.
 
   In the event of a sale or other disposition of all of the assets of any
Subsidiary Guarantor, by way of merger, consolidation or otherwise, or a sale
or other disposition of all of the capital stock of any Subsidiary

Guarantor, or, if a Subsidiary Guarantor is designated as an Unrestricted
Subsidiary, then such Subsidiary Guarantor (in the event of a sale or other
disposition, by way of such a merger, consolidation or otherwise, of all of the
capital stock of or a redesignation of such Subsidiary Guarantor) or the entity
acquiring the property (in the event of a sale or other disposition of all of
the assets of such Subsidiary Guarantor) will be released and relieved of any
obligations under its Senior Subsidiary Guarantee; provided that the Net
Proceeds of such sale or other disposition are applied in accordance with or
the redesignation is accomplished in accordance with the applicable provisions
of the Senior Notes Indenture. See "--Repurchase at the Option of Holders--
Asset Sales."
 
   The Authority currently has no Subsidiaries.
 
  Sale and Leaseback Transactions
 
   The Senior Notes Indenture will provide that the Authority will not, and
will not permit any of its Restricted Subsidiaries to, enter into any sale and
leaseback transaction involving the Resort; provided that the Authority or any
of its Restricted Subsidiaries may enter into a sale and leaseback transaction
if
 
     (1) the Authority or such Restricted Subsidiary, as applicable, could
  have (a) incurred Indebtedness in an amount equal to the Attributable Debt
  relating to such sale and leaseback transaction pursuant to the Fixed
  Charge Coverage Ratio test shown in the first paragraph of the covenant
  described above under the caption "--Incurrence of Indebtedness and
  Issuance of Preferred Stock" and (b) incurred a Lien to secure such
  Indebtedness pursuant to the covenant described above under the caption "--
  Liens";
 
     (2) the gross cash proceeds of such sale and leaseback transaction are
  at least equal to the fair market value, as determined in good faith by the
  Management Board and shown in an Officers' Certificate delivered to the
  Senior Trustee, of the property that is subject of such sale and leaseback
  transaction; and
 
     (3) the transfer of assets in such sale and leaseback transaction is
  permitted by, and the Authority applies the proceeds of such transaction in
  compliance with, the covenant described above under the caption "--
  Repurchase at the Option of Holders--Asset Sales"; provided that, upon the
  occurrence of a Rating Event Date and for so long as the covenants shown
  under the caption entitled "--Changes in Covenants when Senior Exchange
  Notes Rated Investment Grade" continue to be Suspended Covenants, the
  following provisions shall replace the foregoing provisions with respect to
  sale and leaseback transactions by the Authority and its Restricted
  Subsidiaries: The Senior Notes Indenture will provide that Authority will
  not, and will not permit any of its Restricted to Subsidiaries to, enter
  into any sale and leaseback transaction involving the Resort; provided that
  the Authority or any Restricted Subsidiary may enter into any sale and
  leaseback transaction with an Attributable Value (when taken together with
  all other sale and leaseback transactions of the Authority and its
  Restricted Subsidiaries) that, at the time of such transaction, after
  giving effect thereto, does not exceed 10% of Consolidated Net Tangible
  Assets.
 
  Construction
 
   The Authority will use its commercially reasonable best efforts to cause
construction of the Expansion Project to be prosecuted with diligence and
continuity in good and workmanlike manner materially in accordance with the
plans relating to the Expansion Project as more fully described in this
Prospectus.
 
  Restrictions on Leasing and Dedication of Property
 
   Except as provided below, the Authority will not lease, sublease, or grant a
license, concession or other agreement to occupy, manage or use any material
portion of the Authority's property and assets owned or leased by the Authority
(each, a "Lease Transaction").
 
                                       85
<PAGE>
 
   The first paragraph of this covenant will not prohibit any of the following
Lease Transactions:
 
     (1) The Authority may enter into a Lease Transaction with respect to any
  space with any Person (including, without limitation, a lease in connection
  with the Expansion Project for the purpose of developing, constructing,
  operating and managing retail establishments within the Resort), provided
  that:
 
       (a) such Lease Transaction will not materially interfere with,
    impair or detract from the operations of the Resort;
 
       (b) such Lease Transaction contains rent and such other terms such
    that the Lease Transaction, taken as a whole is commercially reasonable
    in light of prevailing or comparable transactions in other casinos,
    hotels, attractions or shopping venues; and
 
       (c) such Lease Transaction complies with all applicable law,
    including obtaining any consent of the BIA, if required;
 
     (2) The Lease and any amendments, extensions, modifications or renewals
  thereof which are not materially adverse to the holders;
 
     (3) The Authority may enter into a management or operating agreement
  with respect to any of the Authority's property and assets with any Person;
  provided that
 
       (a) the manager or operator has experience in managing or operating
    similar operations; and
 
       (b) such management or operating agreement is on commercially
    reasonable and fair terms to the Authority; and
 
     (4) The Relinquishment Agreement, the Development Services Agreement and
  the Side Letters with the Manager and any amendments, extensions,
  modifications or renewals thereof which are not materially adverse to the
  holders.
 
   No Lease Transaction may provide that the Authority may subordinate its
leasehold or fee interest to any lessee or any financing party of any lessee,
and no person other than the Authority may conduct gaming or casino operations
on any property which is the subject of a Lease Transaction.
 
  Covenants of the Tribe
 
   The Tribe shall not, and shall not permit any of its representatives,
political subunits or councils, agencies, instrumentalities, directly or
indirectly, except as required by federal or state law, to do any of the
following:
 
     (1) increase or impose any tax or other payment obligation on the
  Authority or on any patrons of, or any activity at, the Resort other than:
 
       (a) payments which are due under any agreement in effect on the
    Closing Date or payments which are not materially adverse to the
    economic interests of holders;
 
       (b) payments which the Authority has agreed to reimburse each holder
    for the economic effect thereof, if any;
 
       (c) payments which correspondingly reduce the Restricted Payments
    otherwise payable to the Tribe;
 
       (d) pursuant to the Tribal Tax Code; or
 
       (e) Government Service Payments;
 
     (2) amend the terms of the Lease in any material manner that would be
  materially adverse to the economic interests of holders;
 
                                      86
<PAGE>
 
     (3) amend the Tribal Gaming Ordinance in effect on the Closing Date
  (unless any such amendment is a legitimate effort to ensure that the
  Authority and the Resort conduct gaming operations in a manner that is
  consistent with applicable laws, rules and regulations or that protects the
  environment, the public health and safety, or the integrity of the
  Authority or the Resort), restrict or eliminate the exclusive right of the
  Authority to conduct gaming operations on any property owned or controlled
  by the Tribe in a manner that would be materially adverse to the economic
  interests of holders; or
 
     (4) take any other action, enter into any agreement, amend its
  constitution or enact any ordinance, law, rule or regulation that would
  have a material adverse effect on the economic interests of holders.
 
   The Tribe shall comply with all material terms of a construction reserve
disbursement agreement and shall not amend and shall not permit any of its
representatives, political subunits or councils, agencies, instrumentalities,
directly or indirectly, to amend, except as required by federal or state law,
such construction reserve agreement in a manner that would have a material
adverse effect on the economic interests of holders.
 
   Moreover, except with the consent of a majority in interest of holders or as
required by federal or state law, the Tribe shall not, and shall not permit any
of its representatives, political subunits or councils, agencies,
instrumentalities, to, directly or indirectly impose, tax or otherwise make a
charge on the Senior Exchange Notes, the Senior Notes Indenture or any payments
or deposits to be made thereunder.
 
   Upon any payment or distribution of assets upon any liquidation,
dissolution, winding up, reorganization, assignment for the benefit of
creditors, marshalling of assets or any bankruptcy, insolvency or similar
proceedings of the Authority or the Resort, the holders of the Senior Exchange
Notes shall be entitled to receive payment in full in respect to all principal,
premium, interest and other amounts owing in respect of the Notes before any
payment or any distribution to the Tribe.
 
  Changes in Covenants when Senior Exchange Notes Rated Investment Grade
 
   Following the first date upon which the Senior Exchange Notes are rated Baa3
or better by Moody's Investors Service, Inc. ("Moody's") and BBB- or better by
Standard & Poor's Ratings Group ("S&P") (or, in either case, if such person
ceases to rate the Senior Exchange Notes for reasons outside of the control of
the Authority, the equivalent investment grade credit rating from any other
"nationally recognized statistical rating organization" (within the meaning of
Rule 15c3-1(c)(2)(vi)(F) under the Exchange Act) selected by the Authority as a
replacement agency) (the "Rating Event Date") and provided no Event of Default
or event that with notice or the passage of time would constitute an Event of
Default shall exist on the Rating Event Date, the covenants specifically listed
under "--Repurchase at the Option of Holders--Asset Sales," "--Incurrence of
Indebtedness and Issuance of Preferred Stock," "--Restricted Payments," "--
Limitation on Issuances and Sales of Equity Interests in Wholly Owned
Restricted Subsidiaries," "--Dividend and Other Payment Restrictions Affecting
Restricted Subsidiaries," "--Construction," "--Restrictions on Leasing and
Dedication of Property," "--Provisions Common to Both Senior Exchange Notes and
Senior Subordinated Exchange Notes--Certain Common Covenants--Maintenance of
Insurance" and "--Transactions with Affiliates" in this Prospectus
(collectively, the "Suspended Covenants") will no longer be applicable to the
Senior Exchange Notes; provided however that if at any time after a Rating
Event Date, the Senior Exchange Notes shall be rated lower than Baa3 by Moody's
or lower than BBB- by S&P, or any equivalent rating by a successor agency to
Moody's or S&P, the Suspended Covenants shall be automatically reinstated (the
"Reinstated Covenants") and all transactions by the Authority that occurred
during the time that such covenants were suspended and that would have violated
such covenants had such covenants been in effect at the time shall be deemed
not to constitute a Default or an Event of Default, as the case may be, and
shall be deemed to have been in compliance with such covenants for all
purposes; provided further that thereafter all transactions by the Authority
occurring on or after the date on which the Suspended Covenants have been
reinstated shall be required to be in compliance with the Reinstated Covenants.
For purposes of interpreting the definition of "Permitted Liens" during the
time any Suspended Covenants are suspended, the definition should be read as if
the Suspended Covenants were not so suspended.

   There can be no assurance that a Rating Event Date will occur or, if one
occurs, that the Senior Exchange Notes will continue to maintain an investment
grade rating.
 
Description of the Senior Subordinated Exchange Notes
 
 Ranking
 
   These Senior Subordinated Exchange Notes
 
  .  are unsecured general obligations of the Authority; and
 
  .  are subordinated in right of payment to all existing and future Senior
     Indebtedness of the Authority, including without limitation, up to $500
     million of indebtedness under the Loan Agreement and $200 million in
     principal amount of Senior Exchange Notes.
 
 Subsidiaries
 
   As of the date of the Senior Subordinated Notes Indenture, the Authority had
no Subsidiaries. However, the Senior Subordinated Notes Indenture permits the
Authority to create Subsidiaries and generally requires that these Subsidiaries
be designated as Restricted Subsidiaries (i.e., subject to the terms of the
Senior Subordinated Notes Indenture) unless certain conditions are met. If
these conditions are met, the Authority will be permitted to designate a
Subsidiary as an Unrestricted Subsidiary, and Unrestricted Subsidiaries will
not be subject to many of the restrictive covenants of the Senior Subordinated
Notes Indenture.
 
 Principal, Maturity and Interest
 
   The Authority will issue Senior Subordinated Exchange Notes with a maximum
aggregate principal amount of $300 million. The Authority will issue Senior
Subordinated Exchange Notes in denominations of $1,000 and integral multiples
of $1,000. The Senior Subordinated Exchange Notes will mature on January 1,
2009.
 
   Interest on these Senior Subordinated Exchange Notes will accrue at the rate
of 8 3/4% per annum and will be payable semi-annually in arrears on January 1
and July 1, beginning on July 1, 1999. The Authority will make each interest
payment to the holders of record of these Senior Subordinated Exchange Notes on
the immediately preceding December 15 and June 15.
 
   Interest on these Senior Subordinated Exchange Notes accrues from the date
of original issuance or, if interest has already been paid, from the date it
was most recently paid. Interest is computed on the basis of a 360-day year
comprised of twelve 30-day months.
 
 Subordination
 
   The payment of principal, premium and interest, if any, on the Senior
Subordinated Exchange Notes and the Senior Subordinated Subsidiary Guarantees,
if any, is subordinated to the prior payment in full of all Senior Indebtedness
of the Authority including, without limitation, the Senior Exchange Notes and
the Loan Agreement. In the event of any distribution to creditors
 
     (1) in a liquidation or dissolution of the Authority or the Tribe;
 
     (2) in a bankruptcy, reorganization, insolvency, receivership or similar
  proceeding relating to the Authority, the Tribe or their respective
  property;
 
     (3) in an assignment for the benefit of creditors; or
 
     (4) in any marshalling of the Authority's or the Tribe's assets and
  liabilities;
 
 
                                       88
<PAGE>
 
the holders of Senior Indebtedness will be entitled to receive payment in full
of all Obligations due in respect of Senior Indebtedness (including interest
after the commencement of any such proceeding at the rate specified in the
applicable Senior Indebtedness) before the holders of Senior Subordinated
Exchange Notes will be entitled to receive any payment with respect to the
Senior Subordinated Exchange Notes (except that holders of Senior Subordinated
Exchange Notes may receive and retain Permitted Junior Securities and payments
made from the trust described under "--Provisions Common to Both Senior
Exchange Notes and Senior Subordinated Exchange Notes--Legal Defeasance and
Covenant Defeasance").
 
   The Authority also may not make any payment in respect of the Senior
Subordinated Exchange Notes (except in Permitted Junior Securities or from the
trust described under "--Provisions Common to Both Senior Exchange Notes and
Senior Subordinated Exchange Notes--Legal Defeasance and Covenant Defeasance")
if
 
     (1) a payment default on Designated Senior Indebtedness occurs and is
  continuing beyond any applicable grace period; or
 
     (2) any other default occurs and is continuing on Designated Senior
  Indebtedness that permits holders of the Designated Senior Indebtedness to
  accelerate its maturity and the Senior Subordinated Trustee receives a
  notice of such default (a "Payment Blockage Notice") from the Authority or
  the holders of any Designated Senior Indebtedness.
 
   Payments on the Senior Subordinated Exchange Notes may and shall be resumed
 
     (1) in the case of a payment default, upon the date on which all Senior
  Indebtedness is paid in full in cash or such default is cured or waived in
  writing; and
 
     (2) in case of a nonpayment default, the earlier of the date on which
  such nonpayment default is cured or waived or 179 days after the date on
  which the applicable Payment Blockage Notice is received, unless the
  maturity of any Designated Senior Indebtedness has been accelerated.
 
   No new Payment Blockage Notice may be delivered unless and until
 
     (1) 360 days have elapsed since the effectiveness of the immediately
  prior Payment Blockage Notice; and
 
     (2)  all scheduled payments of principal, premium and interest on the
  Senior Subordinated Exchange Notes that have come due have been paid in
  full in cash.
 
   No nonpayment default that existed or was continuing on the date of delivery
of any Payment Blockage Notice to the Senior Subordinated Trustee shall be, or
be made, the basis for a subsequent Payment Blockage Notice unless such default
shall have been cured or waived for a period of not less than 180 days.
 
   The Authority must promptly notify holders of Senior Indebtedness if payment
of the Senior Subordinated Exchange Notes is accelerated because of an Event of
Default.
 
   As a result of the subordination provisions described above, in the event of
a bankruptcy, liquidation or reorganization of the Authority or the Tribe,
holders of these Senior Subordinated Exchange Notes may recover less ratably
than holders of Senior Indebtedness. See "Risk Factors--Unsecured Ranking and
Subordination to Existing Indebtedness--Senior Subordinated Exchange Notes."
 
 Optional Redemption
 
   If, at any time after the Issue Date, any Gaming Regulatory Authority
requires a holder to be licensed or otherwise qualified under applicable gaming
laws in order for the Authority to maintain any of its gaming licenses or
franchises and the holder does not obtain such license or qualification within
the time periods
 
                                       89
<PAGE>
 
described in the Senior Subordinated Notes Indenture and at its own cost and
expense, then the Authority will have the right to either
 
  .  require the holder to dispose of its Senior Subordinated Exchange Notes
     within the time period specified by the Gaming Regulatory Authority or
     30 days, whichever is shorter; or
 
  .  redeem the holder's Senior Subordinated Exchange Notes at a price equal
     to the lesser of (1) the principal amount of the Senior Subordinated
     Exchange Notes held by the holder, (2) the price paid for the Senior
     Subordinated Exchange Notes by the holder, and (3) the current market
     price of the Senior Subordinated Exchange Notes, in each case, including
     all accrued and unpaid interest and Additional Interest, if any, to the
     redemption date or the date a finding of unsuitability is made by the
     applicable Gaming Regulatory Authority, if earlier.
 
   The Authority will comply with the redemption procedures for the Senior
Subordinated Exchange Notes described in the Senior Subordinated Notes
Indenture unless otherwise required by a Gaming Regulatory Authority.
 
   Except as described above, the Senior Subordinated Exchange Notes will not
be redeemable at the Authority option before January 1, 2004.
 
   On or after January 1, 2004, the Authority may redeem all or a part of these
Senior Subordinated Exchange Notes upon not less than 30 nor more than 60 days'
notice, at the redemption prices (expressed as percentages of principal amount)
shown below plus accrued and unpaid interest thereon, if any, to the applicable
redemption date, if redeemed during the 12-month period beginning on January 1
of the years indicated below:

            2007 and thereafter...............  100.000%
</TABLE>
 
 Selection and Notice
 
   If less than all of the Senior Subordinated Exchange Notes are to be
redeemed at any time, the Senior Subordinated Trustee will select Senior
Subordinated Exchange Notes for redemption as follows:
 
     (1) if the Senior Subordinated Exchange Notes are listed, in compliance
  with the requirements of the principal national securities exchange on
  which the Senior Subordinated Exchange Notes are listed; or
 
     (2) if the Senior Subordinated Exchange Notes are not so listed, on a
  pro rata basis, by lot or by such method as the Senior Subordinated Trustee
  shall deem fair and appropriate.
 
   No Senior Subordinated Exchange Notes of $1,000 or less shall be redeemed in
part. Notices of redemption shall be mailed by first class mail at least 30 but
not more than 60 days before the redemption date to each holder of Senior
Subordinated Exchange Notes to be redeemed at its registered address. Notices
of redemption may not be conditional.
 
   If any Senior Subordinated Exchange Note is to be redeemed in part only, the
notice of redemption that relates to that Senior Subordinated Exchange Note
shall state the portion of the principal amount thereof to be redeemed. A new
Senior Subordinated Exchange Note in principal amount equal to the unredeemed
portion of the original Senior Subordinated Exchange Note will be issued in the
name of the holder thereof upon cancellation of the original Senior
Subordinated Exchange Note. Senior Subordinated Exchange Notes called for
redemption become due on the date fixed for redemption. On and after the
redemption date, interest ceases to accrue on Senior Subordinated Exchange
Notes or portions of them called for redemption.

<PAGE>
 
 Repurchase at the Option of Holders
 
  Change of Control
 
   If a Change of Control occurs, each holder of the Senior Subordinated
Exchange Notes will have the right to require the Authority to repurchase all
or any part (equal to $1,000 or an integral multiple thereof) of that holder's
Senior Subordinated Exchange Notes pursuant to a Change of Control Offer. In
the Change of Control Offer, the Authority will offer a Change of Control
Payment in cash equal to 101% of the aggregate principal amount of Senior
Subordinated Exchange Notes repurchased plus accrued and unpaid interest and
Additional Interest, if any, thereon, to the date of purchase.
 
   Within 20 business days following any Change of Control, the Authority will
mail a notice to each holder (and, unless the Senior Subordinated Trustee makes
the mailing on behalf of the Authority, to the Senior Subordinated Trustee)
describing the transaction or transactions that constitute the Change of
Control and offering to repurchase Senior Subordinated Exchange Notes on the
Change of Control Payment Date specified in such notice, pursuant to the
procedures required by the Indenture and described in such notice. If the
Authority wishes the Senior Subordinated Trustee to do the mailing, it will
give the Senior Subordinated Trustee adequate prior notice so that the Senior
Subordinated Trustee may do so. The Authority will comply with the requirements
of Rule 14e-1 under the Exchange Act and any other securities laws and
regulations thereunder to the extent such laws and regulations are applicable
in connection with the repurchase of the Senior Subordinated Exchange Notes as
a result of a Change of Control.
 
   On the Change of Control Payment Date, the Authority, to the extent lawful
will,
 
     (1) accept for payment all Senior Subordinated Exchange Notes or
  portions thereof properly tendered pursuant to the Change of Control Offer;
 
     (2) deposit with the Paying Agent an amount equal to the Change of
  Control Payment in respect of all Senior Subordinated Exchange Notes or
  portions thereof so tendered; and
 
     (3) deliver or cause to be delivered to the Senior Subordinated Trustee
  the Senior Subordinated Exchange Notes so accepted together with an
  Officers' Certificate stating the aggregate principal amount of Senior
  Subordinated Exchange Notes or portions thereof being purchased by the
  Authority.
 
   The Paying Agent will promptly mail to each holder of Senior Subordinated
Exchange Notes so tendered the Change of Control Payment for such Senior
Subordinated Exchange Notes, and the Senior Subordinated Trustee will promptly
authenticate and mail (or cause to be transferred by book entry) to each holder
a new Senior Subordinated Note equal in principal amount to any unpurchased
portion of the Senior Subordinated Exchange Notes surrendered, if any; provided
that each such new Senior Subordinated Note will be in a principal amount of
$1,000 or an integral multiple thereof. The Authority will notify the Senior
Subordinated Trustee and will instruct the Senior Subordinated Trustee to
notify the holders of the results of the Change of Control Offer on or as soon
as practicable after the Change of Control Payment Date.
 
   Except as described above with respect to a Change of Control, the Senior
Subordinated Notes Indenture does not contain provisions that permit the
holders of the Senior Subordinated Exchange Notes to require that the Authority
repurchase or redeem the Senior Subordinated Exchange Notes in the event of a
takeover, recapitalization or similar transaction.
 
   The Loan Agreement will prohibit and the Senior Note Indenture may prohibit
the Authority from purchasing any Senior Subordinated Exchange Notes upon a
Change of Control. The Loan Agreement will also provide that certain change of
control events with respect to the Authority will constitute a default under
the Loan Agreement. Any future credit agreements or other agreements relating
to secured indebtedness to which
 
                                       91
<PAGE>
 
the Authority becomes a party may contain similar restrictions and provisions.
In the event a Change of Control occurs at a time when the Authority is
prohibited from purchasing Senior Subordinated Exchange Notes, the Authority
could seek the consent of its lenders and other creditors to the purchase of
Senior Subordinated Exchange Notes or could attempt to refinance the borrowings
that contain such prohibition. If the Authority does not obtain such a consent
or repay such borrowings, the Authority will remain prohibited from purchasing
Senior Subordinated Exchange Notes. In such case, the Authority's failure to
purchase tendered Senior Subordinated Exchange Notes would constitute an Event
of Default under the Senior Subordinated Notes Indenture which would, in turn,
constitute a default under the Loan Agreement and the Senior Subordinated Notes
Indenture.
 
   The Authority will not be required to make a Change of Control Offer upon a
Change of Control if a third party makes the Change of Control Offer in the
manner, at the times and otherwise in compliance with the requirements shown in
the Senior Subordinated Notes Indenture applicable to a Change of Control Offer
made by the Authority and purchases all Senior Subordinated Exchange Notes
validly tendered and not withdrawn under such Change of Control Offer.
 
  Asset Sales
 
   The Authority will not, and will not permit any of its Restricted
Subsidiaries to, consummate an Asset Sale unless
 
     (1) the Authority (or its Restricted Subsidiary, as the case may be)
  receives consideration at the time of such Asset Sale at least equal to the
  fair market value (as determined in good faith by the Management Board and
  evidenced by a resolution shown in an Officers' Certificate delivered to
  the Senior Subordinated Trustee) of the assets sold or otherwise disposed
  of; and
 
     (2) except in the case of a Permitted Asset Swap, at least 75% of the
  consideration therefor received by the Authority or such Restricted
  Subsidiary is in the form of cash. For purposes of this provision, each of
  the following shall be deemed to be cash:
 
       (a) any liabilities that would appear on the Authority's or such
    Restricted Subsidiary's balance sheet prepared in accordance with GAAP
    (other than contingent liabilities and liabilities that are by their
    terms subordinated to the Senior Subordinated Exchange Notes or any
    guarantee thereof) that are assumed by the transferee of any such
    assets pursuant to a customary novation agreement that releases the
    Authority or such Restricted Subsidiary from further liability; and
 
       (b) any securities, notes or other obligations received by the
    Authority or any such Restricted Subsidiary from such transferee that
    are converted by the Authority or such Restricted Subsidiary into cash
    (to the extent of the cash received) within 30 days of the receipt
    thereof,
 
provided, however, that the Authority will not be permitted to make any Asset
Sale of Key Project Assets.
 
   Within 360 days after the receipt of any Net Proceeds from an Asset Sale,
the Authority may apply such Net Proceeds, at its option, to
 
     (1) repay permanently term Indebtedness under Credit Facilities of the
  Authority or any Restricted Subsidiary;
 
     (2) repay revolving credit Indebtedness under Credit Facilities and
  correspondingly permanently reduce commitments with respect thereto;
 
     (3) acquire a majority of the assets of, or a majority of the Voting
  Stock of, an entity engaged in the Principal Business or a Related
  Business;
 
     (4) make capital expenditures or acquire other long-term assets that are
  used or useful in the Principal Business or a Related Business;
 
 
                                       92
<PAGE>
 
     (5) make an investment in the Principal Business or a Related Business
  or in tangible long-term assets used or useful in the Principal Business or
  a Related Business; or
 
     (6) reduce permanently Indebtedness (including the Senior Exchange
  Notes) that is not Subordinated Indebtedness.
 
   Pending the final application of any such Net Proceeds, the Authority may
temporarily reduce revolving credit borrowings or otherwise invest such Net
Proceeds in any manner that is not prohibited by the Senior Subordinated Notes
Indenture.
 
   Any Net Proceeds from Asset Sales that are not applied or invested as
provided in the preceding paragraph will be deemed to constitute "Excess
Proceeds." When the aggregate amount of Excess Proceeds exceeds $15.0 million,
the Authority will make an Asset Sale Offer to all holders of Senior
Subordinated Exchange Notes and all holders of other Indebtedness containing
provisions similar to those shown in the Senior Subordinated Notes Indenture
with respect to offers to purchase or redeem with the proceeds of sales of
assets to purchase the maximum principal amount of Senior Subordinated Exchange
Notes and such other Indebtedness that may be purchased out of the Excess
Proceeds. The offer price in any Asset Sale Offer will be equal to 100% of the
principal amount plus accrued and unpaid interest and Additional Interest, if
any, to the date of purchase and will be payable in cash, in accordance with
the procedures shown in the Senior Subordinated Notes Indenture and such other
Indebtedness. To the extent that any Excess Proceeds remain after consummation
of an Asset Sale Offer, the Authority may use such Excess Proceeds for any
purpose not otherwise prohibited by the Senior Subordinated Notes Indenture. If
the aggregate principal amount of Senior Subordinated Exchange Notes and such
other Indebtedness tendered into such Asset Sale Offer surrendered by holders
thereof exceeds the amount of Excess Proceeds, the Senior Subordinated Trustee
shall select the Senior Subordinated Exchange Notes and such other Indebtedness
(to the extent that such other Indebtedness permits such selection) to be
purchased on a pro rata basis. Upon completion of such offer to purchase, the
amount of Excess Proceeds shall be reset at zero.
 
 Certain Covenants
 
  Restricted Payments
 
   The Authority will not, and the Authority will not permit any of its
Restricted Subsidiaries, directly or indirectly, to
 
     (1) make any payment on or with respect to any of the Authority's or any
  of its Restricted Subsidiaries' Equity Interests;
 
     (2) purchase, redeem, defease or otherwise acquire or retire for value
  any Equity Interest in the Authority held by the Tribe or any Affiliate of
  the Tribe;
 
     (3) make any payment on or with respect to, or purchase, redeem, defease
  or otherwise acquire or retire for value any Subordinated Indebtedness
  (other than the defeasance and ultimate redemption of the junior
  subordinated notes in accordance with their terms and the terms of the
  Defeasance Trust, except a payment of interest or principal at Stated
  Maturity thereof;
 
     (4) make any payment or distribution to the Tribe (or any other agency,
  instrumentality or political subunit thereof) or make any general
  distribution to the members of the Tribe (other than Government Service
  Payments); or
 
     (5) make any Restricted Investment;
 
(all such payments and other actions shown in clauses (1) through (5) above are
collectively referred to as "Restricted Payments") unless, at the time of and
after giving effect to such Restricted Payment
 
     (A) no Default or Event of Default shall have occurred and be continuing
  or would occur as a consequence thereof;
 
                                       93
<PAGE>
 
     (B) the Authority would, at the time of such Restricted Payment and
  after giving pro forma effect thereto as if such Restricted Payment had
  been made at the beginning of the applicable four-quarter period, have been
  permitted to incur at least $1.00 of additional Indebtedness pursuant to
  the Fixed Charge Coverage Ratio test shown in the first paragraph of the
  covenant described below under the caption "--Incurrence of Indebtedness
  and Issuance of Preferred Stock"; and
 
     (C) such Restricted Payment, together with the aggregate amount of all
  other Restricted Payments made by the Authority and its Restricted
  Subsidiaries after the date of the Senior Subordinated Notes Indenture
  (excluding Restricted Payments permitted by clauses (2), (3), (4) and (5)
  of the next succeeding paragraph), is less than the sum, without
  duplication, of
 
       (i) 50% of the Consolidated Net Income of the Authority for the
    period (taken as one accounting period) from the beginning of the first
    fiscal quarter commencing after the date of the Senior Subordinated
    Notes Indenture to the end of the Authority's most recently ended
    fiscal quarter for which internal financial statements are available at
    the time of such Restricted Payment (or, if such Consolidated Net
    Income for such period is a deficit, less 100% of such deficit), plus
    (ii) 100% of the aggregate net cash proceeds or fair market value (as
    determined in good faith by the Management Board and evidenced by a
    resolution shown in an Officers' Certificate delivered to the Senior
    Subordinated Trustee) of assets or property (other than cash) received
    by the Authority from capital contributions from the Tribe that bear no
    mandatory obligation to repay the Tribe and other than from a
    Restricted Subsidiary of the Authority, plus (iii) to the extent that
    any Restricted Investment that was made after the date of the Senior
    Subordinated Notes Indenture is sold, liquidated or otherwise disposed
    of for cash or an amount equal to the fair market value thereof (as
    determined in good faith by the Management Board and evidenced by a
    resolution shown in an Officers' Certificate delivered to the Senior
    Subordinated Trustee), the lesser of (a) the cash return of capital or
    fair market value amount, as the case may be, with respect to such
    Restricted Investment (less the cost of disposition, if any) and (b)
    the initial amount of such Restricted Investment plus (iv) to the
    extent that any Unrestricted Subsidiary is redesignated as a Restricted
    Subsidiary after the date of the Senior Subordinated Notes Indenture,
    the lesser of (a) the fair market value of the Authority's Investment
    in such Subsidiary as of the date of such redesignation or (b) such
    fair market value as of the date on which such Subsidiary was
    originally designated as an Unrestricted Subsidiary.
 
   So long as no Default has occurred and is continuing or would be caused
thereby, the preceding provisions will not prohibit
 
     (1) the defeasance, redemption, repurchase or other acquisition of
  Subordinated Indebtedness with the net cash proceeds from an incurrence of
  Permitted Refinancing Indebtedness;
 
     (2) the payment of any dividend by a Restricted Subsidiary of the
  Authority to the holders of its common Equity Interests on a pro rata
  basis;
 
     (3) the repurchase, redemption or other acquisition or retirement for
  value of any Equity Interests of any Restricted Subsidiary of the Authority
  held by any member of the Authority's (or any of its Restricted
  Subsidiaries') management pursuant to any management equity subscription
  agreement or stock option agreement in effect as of the date of the Senior
  Subordinated Notes Indenture; provided that (a) the aggregate price paid
  for all such repurchased, redeemed, acquired or retired Equity Interests
  shall not exceed $1.0 million in any 12-month period and (b) the aggregate
  amount of all such repurchased, redeemed, acquired or retired Equity
  Interests shall not in the aggregate exceed $3.0 million;
 
     (4) the redemption or purchase of Subordinated Indebtedness of the
  Authority if the holder of such Subordinated Indebtedness has failed to
  qualify or be found suitable or otherwise be eligible by any Gaming
  Regulatory Authority to remain a holder of such Subordinated Indebtedness;
 
     (5) the redemption, defeasance, repurchase or other acquisition or
  retirement of Subordinated Indebtedness with the net cash proceeds from a
  substantially concurrent capital contribution from the Tribe (provided that
  such capital contribution is not counted for purposes of clause (C)(ii)
  above); and
 
 
                                       94
<PAGE>
 
     (6) any other Restricted Payments in an amount not to exceed $20.0
  million at any one time outstanding.
 
   The Authority may designate any Restricted Subsidiary to be an Unrestricted
Subsidiary if such designation would not cause a Default; provided that in no
event shall (i) any entity (including any Subsidiary of the Authority or the
Authority or any operating division thereof) engaged in a Principal Business be
transferred to or held by an Unrestricted Subsidiary or (ii) any Key Project
Assets or Gaming Licenses be transferred to an Unrestricted Subsidiary. In the
event of such designation, all outstanding Investments owned by the Authority
and its Restricted Subsidiaries in the Subsidiary so designated will be deemed
to be an Investment made as of the time of such designation and will reduce the
amount available for Restricted Payments under the first paragraph of this
covenant unless the Investment constitutes a Permitted Investment. All such
outstanding Investments will be deemed to constitute Restricted Payments in an
amount equal to the fair market value of such Investments at the time of such
designation. Such designation will only be permitted if such Restricted Payment
would be permitted at such time and if such Restricted Subsidiary otherwise
meets the definition of an Unrestricted Subsidiary. The Authority may
redesignate an Unrestricted Subsidiary to be a Restricted Subsidiary if such
redesignation would not otherwise cause a Default.
 
   The amount of all Restricted Payments (other than cash) shall be the fair
market value on the date of the Restricted Payment of the asset(s) or
securities proposed to be transferred or issued by the Authority or such
Restricted Subsidiary, as the case may be, pursuant to the Restricted Payment.
The fair market value of any assets or securities that are required to be
valued by this covenant shall be determined by the Management Board whose
resolution with respect thereto shall be delivered to the Senior Subordinated
Trustee. Not later than the date of making any Restricted Payment, the
Authority shall deliver to the Senior Subordinated Trustee an Officers'
Certificate stating that such Restricted Payment is permitted and setting forth
the basis upon which the calculations required by the covenant "--Restricted
Payments" were computed.
 
  Ranking of Payments Under the Relinquishment Agreement
 
   The Authority will not designate the Senior Relinquishment Payments (as
defined in the Relinquishment Agreement) as Designated Senior Indebtedness and
the Authority will not amend Section 6.2 of the Relinquishment Agreement in a
manner adverse to the holders of the Senior Subordinated Exchange Notes.
 
  Incurrence of Indebtedness and Issuance of Preferred Stock
 
   The Authority will not, and will not permit any of its Subsidiaries to,
directly or indirectly, create, incur, issue, assume, guarantee or otherwise
become directly or indirectly liable, contingently or otherwise, with respect
to (collectively, "incur") any Indebtedness (including Acquired Indebtedness)
and the Authority will not issue any Disqualified Stock and will not permit any
of its Subsidiaries to issue any shares of preferred stock; provided, however,
that the Authority may incur Indebtedness (including Acquired Indebtedness) or
issue shares of Disqualified Stock and the Authority's Subsidiaries may incur
Indebtedness or issue preferred stock if the Fixed Charge Coverage Ratio for
the Authority's most recently ended four full fiscal quarters for which
internal financial statements are available immediately preceding the date on
which such additional Indebtedness is incurred would have been at least 2.0 to
1, determined on a pro forma basis (including a pro forma application of the
net proceeds therefrom), as if the additional Indebtedness had been incurred at
the beginning of such four-quarter period. Notwithstanding the foregoing, the
Authority will not issue any Disqualified Stock or any type of Capital Stock
that would violate IGRA.
 
   So long as no Default or Event of Default shall have occurred and be
continuing, or would be caused thereby, the first paragraph of this covenant
will not prohibit the incurrence of any of the following items of Indebtedness:
 
                                       95
<PAGE>
 
     (1) the incurrence by the Authority or its Restricted Subsidiaries of
  Indebtedness and letters of credit pursuant to Credit Facilities; provided
  that the aggregate principal amount of all such Indebtedness and letters of
  credit outstanding under all Credit Facilities, after giving effect to such
  incurrence (with letters of credit being deemed to have a principal amount
  equal to the maximum potential liability of the Authority thereunder), does
  not exceed $500 million less the aggregate amount of all Net Proceeds of
  Asset Sales applied by the Authority or any of its Restricted Subsidiaries
  since the date of the Senior Subordinated Notes Indenture to repay
  Indebtedness under Credit Facilities pursuant to the covenant described
  above under the caption "--Repurchase at the Option of Holders--Asset
  Sales";
 
     (2) the incurrence by the Authority and its Restricted Subsidiaries of
  the Existing Indebtedness;
 
     (3) the incurrence by the Authority of Indebtedness represented by the
  Outstanding Senior Notes and the Senior Exchange Notes;
 
     (4) the incurrence by the Authority of Indebtedness represented by the
  Outstanding Senior Subordinated Notes and the Senior Subordinated Exchange
  Notes;
 
     (5) the incurrence by the Authority or any of its Restricted
  Subsidiaries of Indebtedness represented by Capital Lease Obligations,
  mortgage financings or purchase money obligations, in each case incurred
  for the purpose of financing all or any part of the purchase price of
  furniture, fixtures, equipment or similar assets used or useful in the
  business of the Authority or such Restricted Subsidiary not to exceed 100%
  of the lesser of cost or fair market value of the assets financed and, in
  an aggregate principal amount under this clause not to exceed $25.0 million
  at any time outstanding;
 
     (6) the incurrence by the Authority or any of its Restricted
  Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the
  net proceeds of which are used to refund, refinance, renew, extend, defease
  or replace Indebtedness that was permitted by the Senior Subordinated Notes
  Indenture to be incurred under the first paragraph of this covenant or
  clauses (1), (2) (other than the junior subordinated notes), (3), (4) or
  (5) of this paragraph;
 
     (7) the incurrence by the Authority or any of its Restricted
  Subsidiaries of Hedging Obligations that are incurred for the purpose of
  fixing or hedging interest rate risk with respect to any floating rate
  Indebtedness that is permitted by the terms of the Senior Subordinated
  Notes Indenture to be outstanding;
 
     (8) the guarantee by the Authority or any of its Restricted Subsidiaries
  of any Indebtedness of the Authority or any of its Restricted Subsidiaries
  that was permitted to be incurred by another provision of this covenant;
 
     (9) the incurrence by a Wholly Owned Restricted Subsidiary of
  Indebtedness owed to another Wholly Owned Restricted Subsidiary or to the
  Authority; provided that if at any time any such Wholly Owned Restricted
  Subsidiary ceases to be a Wholly Owned Restricted Subsidiary, any such
  Indebtedness shall be deemed to be an incurrence of Indebtedness for the
  purposes of this covenant;
 
     (10) the incurrence by the Authority or any of its Restricted
  Subsidiaries of additional Indebtedness in an aggregate principal amount
  (or accreted value, as applicable) at any time outstanding, including all
  Permitted Refinancing Indebtedness incurred to refund, refinance or replace
  any Indebtedness incurred pursuant to this clause (10), not to exceed $25.0
  million; or
 
     (11) the incurrence by the Authority's Unrestricted Subsidiaries of Non-
  Recourse Debt, provided, however, that if any such Indebtedness ceases to
  be Non-Recourse Debt of an Unrestricted Subsidiary, such event shall be
  deemed to constitute an incurrence of Indebtedness by a Restricted
  Subsidiary of the Authority that was not permitted by this clause (11).
 
   For purposes of determining compliance with this "--Incurrence of
Indebtedness and Issuance of Preferred Stock" covenant, if an item of proposed
Indebtedness meets the criteria of more than one of the categories of Permitted
Indebtedness described in clauses (1) through (11) above or is entitled to be
incurred
 
                                       96
<PAGE>
 
pursuant to the first paragraph of this covenant, the Authority shall, in its
sole discretion, classify such item of Indebtedness on the date of its
incurrence in any manner that complies with this covenant.
 
  Limitation on Issuances and Sales of Equity Interests in Wholly Owned
 Restricted Subsidiaries
 
   The Authority (i) will not, and will not permit any Wholly Owned Restricted
Subsidiary of the Authority to, transfer, convey, sell, lease or otherwise
dispose of any Equity Interests in any Wholly Owned Restricted Subsidiary of
the Authority to any Person (other than the Authority or another Wholly Owned
Restricted Subsidiary of the Authority), unless (a) such transfer, conveyance,
sale, lease or other disposition is of all the Equity Interests in such Wholly
Owned Restricted Subsidiary and (b) the cash Net Proceeds from such transfer,
conveyance, sale, lease or other disposition are applied in accordance with the
covenant described above under the caption "--Repurchase at the Option of
Holders--Asset Sales," and (ii) will not permit any Wholly Owned Restricted
Subsidiary of the Authority to issue any of its Equity Interests (other than,
if necessary, shares of its Capital Stock constituting directors' qualifying
shares) to any Person other than to the Authority or a Wholly Owned Restricted
Subsidiary of the Authority.
 
  Liens
 
   The Senior Subordinated Notes Indenture will provide that the Authority will
not, and will not permit any of its Restricted Subsidiaries to, directly or
indirectly, create, incur, assume or otherwise cause or suffer to exist or
become effective any Lien of any kind (other than Permitted Liens) upon any of
its property or assets, or any proceeds therefrom, which secure either (a)
Subordinated Indebtedness, unless the Senior Subordinated Exchange Notes are
secured by a Lien on such property, assets or proceeds, which Lien is senior in
priority to the Liens securing such Subordinated Indebtedness or (b) pari passu
Indebtedness, unless the Senior Subordinated Exchange Notes are equally and
ratably secured with the Liens securing such pari passu Indebtedness.
 
  Dividend and Other Payment Restrictions Affecting Restricted Subsidiaries
 
   The Authority will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, create or permit to exist or become
effective any encumbrance or restriction on the ability of any Restricted
Subsidiary to
 
     (1) pay dividends or make any other distributions on its Capital Stock
  to the Authority or any of the Authority's Restricted Subsidiaries, or with
  respect to any other interest or participation in, or measured by, its
  profits, or pay any indebtedness owed to the Authority or any of the
  Authority's Restricted Subsidiaries;
 
     (2) make loans or advances to the Authority or any of the Authority's
  Restricted Subsidiaries; or
 
     (3) transfer any of its properties or assets to the Authority or any of
  the Authority's Restricted Subsidiaries.
 
   However, the preceding restrictions will not apply to encumbrances or
restrictions existing under or by reason of
 
     (1) Existing Indebtedness as in effect on the date of the Senior
  Subordinated Notes Indenture and any amendments, modifications,
  restatements, renewals, extensions, increases, supplements, refundings,
  replacements or refinancings thereof, provided that such amendments,
  modifications, restatements, renewals, extensions, increases, supplements,
  refundings, replacements or refinancings are no more restrictive, taken as
  a whole, with respect to such dividend and other payment restrictions than
  those contained in such Existing Indebtedness, as in effect on the date of
  the Senior Subordinated Notes Indenture;
 
     (2) the Senior Subordinated Notes Indenture and the Senior Subordinated
  Exchange Notes;
 
                                       97
<PAGE>
 
     (3) the Senior Notes Indenture and the Senior Exchange Notes;
 
     (4) the Credit Facilities;
 
     (5) applicable law;
 
     (6) any instrument governing Indebtedness or Capital Stock of a Person
  acquired by the Authority or any of its Restricted Subsidiaries as in
  effect at the time of such acquisition (except to the extent such
  Indebtedness was incurred in connection with or in contemplation of such
  acquisition), which encumbrance or restriction is not applicable to any
  Person, or the properties or assets of any Person, other than the Person,
  or the property or assets of the Person, so acquired, provided that, in the
  case of Indebtedness, such Indebtedness was permitted by the terms of the
  Senior Subordinated Notes Indenture to be incurred;
 
     (7) customary non-assignment provisions in leases or other contracts
  entered into in the ordinary course of business and consistent with past
  practices;
 
     (8) purchase money obligations (including, without limitation, Capital
  Lease Obligations) for property acquired in the ordinary course of business
  that impose restrictions on the property so acquired of the nature
  described in clause (3) of the preceding paragraph;
 
     (9) any agreement for the sale or other disposition of a Restricted
  Subsidiary that restricts distributions by such Restricted Subsidiary
  pending its sale or other disposition;
 
     (10) Permitted Refinancing Indebtedness, provided that the restrictions
  contained in the agreements governing such Permitted Refinancing
  Indebtedness are no more restrictive, taken as a whole, than those
  contained in the agreements governing the Indebtedness being refinanced;
 
     (11) Liens securing Indebtedness otherwise permitted to be incurred
  pursuant to the provisions of the covenant described above under the
  caption "--Liens" that limit the right of the Authority or any of its
  Restricted Subsidiaries to dispose of the assets subject to such Lien;
 
     (12) provisions with respect to the disposition or distribution of
  assets or property in joint venture agreements and other similar agreements
  entered into in the ordinary course of business; and
 
     (13) restrictions on cash or other deposits or net worth imposed by
  customers under contracts entered into in the ordinary course of business.
 
  Transactions with Affiliates
 
   The Authority will not, and the Authority will not permit any of its
Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or
otherwise dispose of any of its properties or assets to, or purchase any
property or assets from, or enter into or make or amend any transaction,
contract, agreement, understanding, loan, advance or guarantee with, or for the
benefit of, any Affiliate (each of the foregoing, an "Affiliate Transaction"),
unless
 
     (1) such Affiliate Transaction is on terms that are no less favorable to
  the Authority or the relevant Restricted Subsidiary than those that would
  have been obtained in a comparable transaction by the Authority or such
  Restricted Subsidiary with an unrelated Person; and
 
     (2) the Authority delivers to the Senior Subordinated Trustee
 
       (a) with respect to any Affiliate Transaction or series of related
    Affiliate Transactions involving aggregate consideration in excess of
    $5.0 million, a resolution of the Management Board shown in an
    Officers' Certificate certifying that such Affiliate Transaction
    complies with this covenant and that such Affiliate Transaction has
    been approved by a majority of the disinterested members of the
    Management Board; and
 
       (b) with respect to any Affiliate Transaction or series of related
    Affiliate Transactions involving aggregate consideration in excess of
    $10.0 million, an opinion as to the fairness to the Authority or such
    Restricted Subsidiary of such Affiliate Transaction from a financial
    point of view issued by an accounting, appraisal or investment banking
    firm of national standing.
 
                                       98
<PAGE>
 
   The following items shall not be deemed to be Affiliate Transactions and,
therefore, will not be subject to the provisions of the prior paragraphs:
 
     (1) any employment agreement or arrangement entered into by the
  Authority or any of its Restricted Subsidiaries in the ordinary course of
  business and consistent with the past practice of the Authority or such
  Restricted Subsidiary;
 
     (2) transactions between or among the Authority and/or its Restricted
  Subsidiaries;
 
     (3) payment of reasonable Management Board fees to members of the
  Management Board;
 
     (4) transactions with Persons in whom the Authority owns any Equity
  Interests, so long as the remaining equity holders of such Person are not
  Affiliates of the Authority or any of its Subsidiaries;
 
     (5) Government Service Payments;
 
     (6) transactions pursuant to the Development Services Agreement, the
  Relinquishment Agreement and the Side Letters;
 
     (7) Restricted Payments or Permitted Investments that are made in
  compliance with the provisions of the Senior Subordinated Notes Indenture
  described above under the caption "--Restricted Payments;" and
 
     (8) contractual arrangements existing on the date of the Senior
  Subordinated Notes Indenture and any renewals, extensions and modifications
  thereof that are not materially adverse to holders.
 
  Subordinated Subsidiary Guarantees
 
   The Senior Subordinated Notes Indenture will provide that if the Authority
acquires or creates any Restricted Subsidiary after the date of the Senior
Subordinated Notes Indenture, then that newly acquired or created Restricted
Subsidiary must become a Subsidiary Guarantor and execute a supplemental
indenture satisfactory to the Senior Subordinated Trustee and deliver an
Opinion of Counsel to the Senior Subordinated Trustee within 20 business days
of the date on which it is acquired or created.
 
   The obligations of each Subsidiary Guarantor under its Senior Subordinated
Subsidiary Guarantee will be limited so as not to constitute a fraudulent
conveyance under applicable law. Any Senior Subordinated Subsidiary Guarantees
will be subordinated to Senior Indebtedness in the same manner and to the same
extent as the Senior Subordinated Exchange Notes.
 
   No Subsidiary Guarantor may consolidate with or merge with or into (whether
or not such Subsidiary Guarantor is the surviving Person), another corporation,
Person or entity whether or not affiliated with such Subsidiary Guarantor
unless: (i) subject to the provisions of the following paragraph, the Person
formed by or surviving any such consolidation or merger (if other than such
Subsidiary Guarantor) assumes all the obligations of such Subsidiary Guarantor
pursuant to a supplemental indenture in form and substance reasonably
satisfactory to the Senior Subordinated Trustee; and (ii) immediately after
giving effect to such transaction, no Default or Event of Default exists.
 
   The Senior Subordinated Notes Indenture will permit the merger of one or
more Subsidiary Guarantors with or into another Subsidiary Guarantor or with or
into the Authority; provided that in the case of a merger with or into the
Authority, the Authority is the surviving entity.
 
   In the event of a sale or other disposition of all of the assets of any
Subsidiary Guarantor, by way of merger, consolidation or otherwise, or a sale
or other disposition of all of the capital stock of any Subsidiary Guarantor or
if a Subsidiary Guarantor is designated as an Unrestricted Subsidiary, then
such Subsidiary Guarantor (in the event of a sale or other disposition, by way
of such a merger, consolidation or otherwise, of all of the capital stock or a
redesignation of such Subsidiary Guarantor) or the entity acquiring the
property (in the event of a sale or other disposition of all of the assets of
such Subsidiary Guarantor) will be released and
 
                                       99
<PAGE>
 
relieved of any obligations under its Senior Subordinated Subsidiary Guarantee;
provided that the Net Proceeds of such sale or other disposition are applied in
accordance with or the redesignation is accomplished in accordance with the
applicable provisions of the Senior Subordinated Notes Indenture. See "--
Repurchase at the Option of Holders--Asset Sales."
 
   The Authority currently has no Subsidiaries.
 
  Sale and Leaseback Transactions
 
   The Senior Subordinated Notes Indenture will provide that the Authority will
not, and will not permit any of its Restricted Subsidiaries to, enter into any
sale and leaseback transaction involving the Resort; provided that the
Authority or any of its Restricted Subsidiaries may enter into a sale and
leaseback transaction if
 
     (1)  the Authority or such Restricted Subsidiary, as applicable, could
  have (a) incurred Indebtedness in an amount equal to the Attributable Debt
  relating to such sale and leaseback transaction pursuant to the Fixed
  Charge Coverage Ratio test shown in the first paragraph of the covenant
  described above under the caption "--Incurrence of Indebtedness and
  Issuance of Preferred Stock" and (b) incurred a Lien to secure such
  Indebtedness pursuant to the covenant described above under the caption "--
  Liens";
 
     (2) the gross cash proceeds of such sale and leaseback transaction are
  at least equal to the fair market value, as determined in good faith by the
  Management Board and shown in an Officers' Certificate delivered to the
  Senior Subordinated Trustee, of the property that is subject of such sale
  and leaseback transaction; and
 
     (3) the transfer of assets in such sale and leaseback transaction is
  permitted by, and the Authority applies the proceeds of such transaction in
  compliance with, the covenant described above under the caption "--
  Repurchase at the Option of Holders--Asset Sales."
 
  Construction
 
   The Authority will use its commercially reasonable best efforts to cause
construction of the Expansion Project to be prosecuted with diligence and
continuity in good and workmanlike manner materially in accordance with the
plans relating to the Expansion Project as more fully described in this
Prospectus.
 
  Restrictions on Leasing and Dedication of Property
 
   Except as provided below, the Authority will not lease, sublease, or grant a
license, concession or other agreement to occupy, manage or use any material
portion of the Authority's property and assets owned or leased by the Authority
(each, a "Lease Transaction").
 
   The first paragraph of this covenant will not prohibit any of the following
Lease Transactions:
 
     (1) The Authority may enter into a Lease Transaction with respect to any
  space with any Person (including, without limitation, a lease in connection
  with the Expansion Project for the purpose of developing, constructing,
  operating and managing retail establishments within the Resort), provided
  that:
 
       (a) such Lease Transaction will not materially interfere with,
    impair or detract from the operations of the Resort;
 
       (b) such Lease Transaction contains rent and such other terms such
    that the Lease Transaction, taken as a whole is commercially reasonable
    in light of prevailing or comparable transactions in other casinos,
    hotels, attractions or shopping venues; and
 
       (c) such Lease Transaction complies with all applicable law,
    including obtaining any consent of the BIA, if required;
 
 
                                      100

     (2) The Lease and any amendments, extensions, modifications or renewals
  thereof which are not materially adverse to the holders;
 
     (3) The Authority may enter into a management or operating agreement
  with respect to any of the Authority's property and assets with any Person;
  provided that

    similar operations; and
 
       (b) such management or operating agreement is on commercially
    reasonable and fair terms to the Authority; and

and no person other than the Authority may conduct gaming or casino operations
on any property which is the subject of a Lease Transaction.
 
   No Senior Subordinated Indebtedness

become liable for any Indebtedness that is subordinate or junior in right of
payment to any Senior Indebtedness of the Authority and senior in any respect
in right of payment to the Senior Subordinated Exchange Notes. No Subordinated
Guarantor will incur, create, issue, assume, guarantee or otherwise become
liable for any Indebtedness that is subordinate or junior in right of payment

respect in right of payment to such Subordinated Guarantor's Subsidiary
Subordinated Guarantee.

indirectly, except as required by federal or state law, to do any of the
following:
 
     (1) increase or impose any tax or other payment obligation on the
  Authority or on any patrons of, or any activity at, the Resort other than:
 
       (a) payments which are due under any agreement in effect on the
    Closing Date or payments which are not materially adverse to the
    economic interests of holders;
 
       (b) payments which the Authority has agreed to reimburse each holder
    for the economic effect thereof, if any;
 
       (c) payments which correspondingly reduce the Restricted Payments
    otherwise payable to the Tribe;
 
       (d) pursuant to the Tribal Tax Code; or
 
       (e) Government Service Payments;
 
     (2) amend the terms of the Lease in any material manner that would be
  materially adverse to the economic interests of holders;
 
     (3) amend the Tribal Gaming Ordinance in effect on March 3, 1999 (unless

  the Resort conduct gaming operations in a manner that is consistent with
  applicable laws, rules and regulations or that protects the environment,
  the public health and safety, or the integrity of the Authority or the
  Resort), restrict or eliminate the exclusive right of the Authority to
  conduct gaming operations on any property owned or controlled by the Tribe
  in a manner that would be materially adverse to the economic interests of
  holders; or
 
 
                                      101
<PAGE>

  have a material adverse effect on the economic interests of holders.
 
   The Tribe shall comply with all material terms of the construction reserve
agreement and shall not amend and shall not permit any of its representatives,
political subunits or councils, agencies, instrumentalities, directly or
indirectly, to amend, except as required by federal or state law, such a
construction reserve agreement in a manner that would have a material adverse
effect on the economic interests of holders.
 
   Moreover, except with the consent of a majority in interest of holders or as
required by federal or state law, the Tribe shall not, and shall not permit any
of its representatives, political subunits or councils, agencies,
instrumentalities, to, directly or indirectly impose, tax or otherwise make a
charge on the Senior Subordinated Exchange Notes, the Senior Subordinated Notes
Indenture or any payments or deposits to be made thereunder.
 
   Upon any payment or distribution of assets upon any liquidation,
dissolution, winding up, reorganization, assignment for the benefit of
creditors, marshalling of assets or any bankruptcy, insolvency or similar
proceedings of the Authority or the Resort, the holders of the Notes shall be
entitled to receive payment in full in respect to all principal, premium,
interest and other amounts owing in respect of the Notes before any payment or
any distribution to the Tribe.
 
Provisions Common to Both Senior Exchange Notes and Senior Subordinated
Exchange Notes
 
 Methods of Receiving Payments on the Notes
 
   If a holder that holds at least $1.0 million in principal amount of Exchange
Notes has given wire transfer instructions to the Authority, the Authority will
make all principal, premium and interest payments, including Additional
Interest payments, if any, on those Exchange Notes in accordance with those
instructions. All other payments on these Exchange Notes will be made at the
office or agency of the Paying Agent and Registrar within the City and State of
New York unless the Authority elects to make interest payments by check mailed
to the holders at their address shown in the register of holders.
 
 Paying Agent and Registrar for the Notes
 
   The Trustees initially will act as Paying Agent and Registrar. The Authority
may change the Paying Agent or Registrar without prior notice to the holders of
the Notes, and the Authority may act as Paying Agent or Registrar.
 
 Transfer and Exchange
 
   A holder may transfer or exchange Exchange Notes in accordance with the
Indentures. The Registrar and the Trustees may require a holder, among other
things, to furnish appropriate endorsements and transfer documents and the
Authority may require a holder to pay any taxes and fees required by law or
permitted by the Indentures. The Authority is not required to transfer or
exchange any Exchange Note selected for redemption. Also, the Authority is not
required to transfer or exchange any Exchange Note for a period of 15 days
before a selection of Exchange Notes to be redeemed.
 
   The registered holder of an Exchange Note will be treated as the owner of it
for all purposes.
 
                                      102
<PAGE>
 
 Certain Common Covenants
 
  Use of Proceeds
 
   The Authority will use the net proceeds of the Outstanding Notes Offering
only for Permitted Proceed Uses.
 
  Gaming Licenses
 
   The Authority will use its best efforts to obtain and retain in full force
and effect at all times all Gaming Licenses necessary for the operation of the
Resort, provided, that, if in the course of the exercise of its governmental or
regulatory functions the Authority is required to suspend or revoke any
consent, permit or license or close or suspend any operation or any part of the
Resort as a result of any noncompliance with the law, the Authority will use
its best efforts to promptly and diligently correct such noncompliance or
replace any personnel causing such noncompliance so that the Resort will be
opened and fully operating.
 
   The Authority shall file with the Trustees and provide holders of Exchange
Notes any Notice of Violation, Order of Temporary Closure, or Assessment of
Civil Fines, from the NIGC pursuant to 25 C.F.R. Part 573 or 575 or any
successor provision, and any Notice of Non-Compliance issued by, or cause of
action commenced by, the State of Connecticut under Section 13 of the Compact,
or any successor provision.
 
  Ownership Interests in the Authority
 
   Neither the Tribe nor the Authority shall permit any Person other than the
Tribe to acquire any Ownership Interest whatsoever in the Authority.
 
  Existence of the Authority and Maintenance of the Lease
 
   The Authority shall, and shall cause each of its Restricted Subsidiaries to,
do or cause to be done all things necessary to preserve and keep in full force
and effect their respective existence, in accordance with their respective
organizational documents and their respective rights (contractual, charter and
statutory), licenses and franchises; provided, however, that neither the
Authority nor any Restricted Subsidiary shall be required to preserve, with
respect to itself, any license, right or franchise and, with respect to its
Restricted Subsidiaries, any such existence, license, right or franchise, if
its Management Board or Board of Directors, or other governing body or officers
authorized to make such determination, as the case may be, shall determine that
the preservation thereof is no longer desirable in the conduct of the business
of the Authority or any Restricted Subsidiary, and that the loss thereof is not
adverse in any material respect to the holders. In addition, the Authority
shall do, or cause to be done, all things necessary to perform any material
covenants shown in the Lease to keep the Lease in full force and effect.
 
  Liquidation or Dissolution
 
   The Authority shall not sell, assign, transfer, lease, convey or otherwise
dispose of all or substantially all of its properties or assets in one or more
transactions. The Authority shall not consolidate or merge with or into any
other Person.
 
  Limitations on Lines of Business
 
   The Authority shall not, and shall not permit any of its Restricted
Subsidiaries to, engage in any business other than the Principal Business or a
Related Business.
 
  Maintenance of Insurance
 
   The Indentures provide that, until the Exchange Notes have been paid in
full, the Authority shall maintain insurance with responsible carriers against
such risks and in such amounts as is customarily carried by similar businesses
with such deductibles, retentions, set insured amounts and coinsurance
provisions as are customarily carried by similar businesses of similar size,
including, without limitation, property and casualty.
 
                                      103
<PAGE>
 
   Customary insurance coverage shall be deemed to include the following:
 
     (1) workers' compensation insurance to the extent required to comply
  with all applicable state, territorial, or United States laws and
  regulations, or the laws and regulations of any other applicable
  jurisdiction;
 
     (2) comprehensive general liability insurance with minimum limits of
  $2.0 million;
 
     (3) umbrella or bumbershoot liability insurance providing excess
  liability coverages over and above the foregoing underlying insurance
  policies up to a minimum limit of $100.0 million; and
 
     (4) property insurance protecting the property against loss or damage by
  fire, lightning, wind-storm, tornado, water damage, vandalism, riot,
  earthquake, civil commotion, malicious mischief, hurricane, and such other
  risks and hazards as are from time to time covered by an "all-risk" policy
  or a property policy covering "special" causes of loss (such insurance
  shall provide coverage of not less than 100% of actual replacement value
  (as determined at each policy renewal based on the F.W. Dodge Building
  Index or some other recognized means) of any improvements and with a
  deductible no greater than $500,000 (other than earthquake insurance, for
  which the deductible may be up to 10% of such replacement value)).
 
 Payments for Consent
 
   The Authority will not and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, pay or cause to be paid any
consideration, to or for the benefit of any holder of any Senior Exchange Notes
or Senior Subordinated Exchange Notes, as the case may be, for or as an
inducement to any consent, waiver or amendment of any of the terms or
provisions of either of the Indentures or the Senior Exchange Notes or Senior
Subordinated Exchange Notes, as the case may be, unless such consideration is
offered to be paid or is paid to all holders of the Senior Exchange Notes or
Senior Subordinated Exchange Notes, as the case may be, that consent, waive or
agree to amend in the time frame shown in the solicitation documents relating
to such consent, waiver or agreement.
 
 Required Defeasance and Redemption of the Junior Subordinated Notes
 
   The Authority will have established, as of the date of the Indentures, the
Defeasance Trust and deposit into the Defeasance Trust cash or government
securities estimated to be sufficient to pay all principal, premium and
interest on the Junior Subordinated Notes less $500,000 on January 1, 2000, the
first redemption date. The Authority will redeem the Junior Subordinated Notes
from the proceeds of the Defeasance Trust on January 1, 2000 at a price of 100%
of the principal amount, plus accrued and unpaid interest thereon, less
$500,000.
 
 Designation of Designated Senior Indebtedness Under the Relinquished Agreement
 
   The Authority will not designate any indebtedness as "Designated Senior
Indebtedness" under the Relinquishment Agreement that is not also designated as
Designated Senior Indebtedness under the Senior Subordinated Notes Indenture.
 
 Reports
 
   Whether or not required by the Commission, so long as any Exchange Notes are
outstanding, the Authority will furnish to the holders of Notes and the
Trustees within 15 days after the end of the time periods specified in the
Commission's rules and regulations for filings of current, quarterly and annual
reports:
 
     (1) all quarterly and annual financial information that would be
  required to be contained in a filing with the Commission on Forms 10-Q and
  10-K if the Authority were required to file such Forms, including a
  "Management's Discussion and Analysis of Financial Condition and Results of
  Operations" that describes the financial condition and results of
  operations of the Authority and its consolidated Subsidiaries (showing in
  reasonable detail, either on the face of the financial statements or in the
  footnotes
 
                                      104
<PAGE>
 
  thereto and in Management's Discussion and Analysis of Financial Condition
  and Results of Operations, the financial condition and results of
  operations of the Authority and its Restricted Subsidiaries separate from
  the financial condition and results of operations of the Unrestricted
  Subsidiaries of the Authority, to the extent that would be required by the
  rules, regulations or interpretive positions of the Commission) and, with
  respect to the annual information only, a report thereon by the Authority's
  independent public accountants; and
 
     (2) all current reports that would be required to be filed with the
  Commission on Form 8-K if the Authority were required to file such reports.
 
   In addition, if the Authority consummates the Exchange Offers, whether or
not required by the rules and regulations of the Commission, the Authority
will file a copy of all such information and reports with the Commission for
public availability within the time periods specified in the Commission's
rules and regulations (unless the Commission will not accept such a filing)
and make such information available to securities analysts and prospective
investors upon request.
 
   In addition, the Authority has agreed that, for so long as any Exchange
Notes remain outstanding, it will furnish to the holders and to securities
analysts and prospective investors, upon their request, the information
required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act.
 
   The Authority shall file with the Trustees and provide to holders of
Exchange Notes, within 15 days after it files them with the NIGC, copies of
all reports which the Authority is required to file with the NIGC pursuant to
25 C.F.R. Part 514.
 
 Events of Default and Remedies
 
   With respect to each of the Senior Exchange Notes and the Senior
Subordinated Exchange Notes, respectively, each of the following is an Event
of Default:
 
     (1) default for 30 days in the payment when due of interest on, or
  Additional Interest with respect to, such Notes;
 
     (2) default in payment when due of the principal of or premium, if any,
  on such Exchange Notes;
 
     (3) failure by the Authority or any of its Restricted Subsidiaries to
  comply with the provisions described under the captions "--Description of
  the Senior Exchange Notes--Repurchase at the Option of Holders--Asset
  Sales," "--Description of the Senior Subordinated Exchange Notes--
  Repurchase at the Option of Holders--Asset Sales" or "--Certain Common
  Covenants--Liquidation or Dissolution";
 
     (4) failure by the Authority or any of its Restricted Subsidiaries for
  (i) 30 days after notice to comply with the provisions described under "--
  Description of the Senior Exchange Notes--Certain Covenants--Restricted
  Payments," "--Description of the Senior Subordinated Exchange Notes--
  Certain Covenants--Restricted Payments," "--Description of the Senior
  Exchange Notes--Certain Covenants--Incurrence of Indebtedness and Issuance
  of Preferred Stock" and "Description of the Senior Subordinated Exchange
  Notes--Certain Covenants--Incurrence of Indebtedness and Issuance of
  Preferred Stock" or (ii) 60 days after notice to comply with any of the
  other agreements in the respective Indentures or the Exchange Notes;
 
     (5) default under any mortgage, indenture or instrument under which
  there may be issued or by which there may be secured or evidenced any
  Indebtedness for money borrowed by the Authority or any of its Restricted
  Subsidiaries (or the payment of which is guaranteed by the Authority or any
  of its Restricted Subsidiaries) whether such Indebtedness or guarantee now
  exists, or is created after the date of the Indenture, if that default
 
       (a) is caused by a failure to pay principal of or premium, if any, or
    interest on such Indebtedness before the expiration of the grace period
    provided in such Indebtedness on the date of such default (a "Payment
    Default"); or
 
                                      105
<PAGE>
 
       (b) results in the acceleration of such Indebtedness before its
    express maturity; and,
 
  in each case, the principal amount of any such Indebtedness, together with
  the principal amount of any other such Indebtedness under which there has
  been a Payment Default or the maturity of which has been so accelerated,
  aggregates $10.0 million or more;
 
     (6) failure by the Authority or any of its Restricted Subsidiaries to
  pay final judgments in amounts not covered by insurance or not adequately
  reserved for in accordance with GAAP aggregating in excess of $10.0
  million, which judgments are not paid, discharged or stayed (by reason of
  pending appeal or otherwise) for a period of 60 days;
 
     (7) certain events of bankruptcy or insolvency with respect to the
  Authority or any of its Restricted Subsidiaries;
 
     (8) revocation, termination, suspension or other cessation of
  effectiveness of any Gaming License which results in the cessation or
  suspension of gaming operations for a period of more than 90 consecutive
  days at the Resort;
 
     (9) cessation of gaming operations for a period of more than 90
  consecutive days at the Resort (other than as a result of a casualty loss);
 
     (10) the Lease ceases to be in full force and effect; and
 
     (11) failure by the Tribe to comply with the provisions described under
  "Covenants of the Tribe" for 30 days after notice to comply.
 
   In the case of an Event of Default arising from certain events of bankruptcy
or insolvency with respect to the Authority, any Restricted Subsidiary that is
a Significant Subsidiary or any group of Restricted Subsidiaries that, taken
together, would constitute a Significant Subsidiary, all outstanding Notes will
become due and payable immediately without further action or notice. If any
other Event of Default occurs and is continuing, a Trustee or the holders of at
least 25% in principal amount of the then outstanding Exchange Notes may
declare all the Exchange Notes to be due and payable immediately.
 
   Holders of the Exchange Notes may not enforce their respective Indentures or
the Exchange Notes except as provided in the Indentures. Subject to certain
limitations, holders of a majority in principal amount of the then outstanding
Exchange Notes may direct a Trustee in its exercise of any trust or power. A
Trustee may withhold from holders of the Exchange Notes notice of any
continuing Default or Event of Default (except a Default or Event of Default
relating to the payment of principal or interest) if it determines that
withholding notice is in their interest.
 
   The holders of a majority in aggregate principal amount of the Exchange
Notes then outstanding by notice to a Trustee may on behalf of the holders of
all of the Exchange Notes waive any existing Default or Event of Default and
its consequences under the respective Indentures except a continuing Default or
Event of Default in the payment of interest on, or the principal of, the
Exchange Notes.
 
   In the case of any Event of Default occurring by reason of any willful
action (or inaction) taken (or not taken) by or on behalf of the Authority with
the intention of avoiding payment of the premium that the Authority would have
had to pay if the Authority then had elected to redeem the Senior Subordinated
Exchange Notes pursuant to the optional redemption provisions of the Senior
Subordinated Notes Indenture, an equivalent premium shall also become and be
immediately due and payable to the extent permitted by law upon the
acceleration of the Senior Subordinated Exchange Notes. If an Event of Default
occurs before January 1, 2004 by reason of any willful action (or inaction)
taken (or not taken) by or on behalf of the Authority with the intention of
avoiding the prohibition on redemption of the Senior Subordinated Exchange
Notes before January 1, 2004, then the premium specified in the Senior
Subordinated Notes Indenture shall also become immediately due and payable to
the extent permitted by law upon the acceleration of the Senior Subordinated
Exchange Notes.
 
 
                                      106
<PAGE>
 
   The Authority will be required to deliver to each Trustee annually a
statement regarding compliance with the Indenture, and the Authority will be
required upon becoming aware of any Default or Event of Default, to deliver to
each Trustee a statement specifying such Default or Event of Default.
 
 No Personal Liability of Limited Partners, Directors, Officers, Employees and
 Stockholders
 
   Neither the Tribe nor any director, officer, office holder, employee, agent,
representative or member of the Authority or the Tribe or holder of an
Ownership Interest of the Authority, any Subsidiary Guarantor or the Tribe, as
such, shall have any liability for any obligations of the Authority under the
Exchange Notes or the Indentures or for any claim based on, in respect of, or
by reason of, such obligations or their creation. Each holder of Exchange Notes
by accepting an Exchange Note waives and releases all such liability. The
waiver and release are part of the consideration for issuance of the Exchange
Notes. Such waiver may not be effective to waive liabilities under the federal
securities laws and it is the view of the Commission that such a waiver is
against public policy.
 
 Legal Defeasance and Covenant Defeasance
 
   The Authority may, at its option and at any time, elect to have all of its
obligations discharged with respect to either or both of the outstanding Senior
Exchange Notes and Senior Subordinated Exchange Notes, ("Legal Defeasance")
except for
 
     (1) the rights of holders of outstanding Exchange Notes to receive
  payments in respect of the principal of, premium, if any, and interest and
  Additional Interest, if any, on such Exchange Notes when such payments are
  due from the trust referred to below;
 
     (2) the Authority's obligations with respect to the Exchange Notes
  concerning issuing temporary Exchange Notes, registration of Outstanding
  Notes, mutilated, destroyed, lost or stolen Exchange Notes and the
  maintenance of an office or agency for payment and money for security
  payments held in trust;
 
     (3) the rights, powers, trusts, duties and immunities of the Trustees,
  and the Authority's obligations in connection with those rights, powers,
  trusts, duties and immunities; and
 
     (4) the Legal Defeasance provisions of the Indentures.
 
     In addition, the Authority may, at its option and at any time, elect to
  have the obligations of the Authority released with respect to certain
  covenants that are described in the Indentures ("Covenant Defeasance") and
  thereafter any omission to comply with such obligations shall not
  constitute a Default or Event of Default with respect to the Exchange
  Notes. In the event Covenant Defeasance occurs, certain events (not
  including non-payment, bankruptcy, receivership, rehabilitation and
  insolvency events) described under "--Events of Default and Remedies" will
  no longer constitute an Event of Default with respect to the Exchange
  Notes.
 
   To exercise either Legal Defeasance or Covenant Defeasance
 
     (1) the Authority shall have irrevocably deposited with the appropriate
  Trustee, in trust, for the benefit of the holders of the Exchange Notes,
  cash in U.S. dollars, non-callable Government Securities, or a combination
  thereof, in such amounts as will be sufficient, in the opinion of a
  nationally recognized firm of independent public accountants, to pay the
  principal of, premium, if any, and interest and Additional Interest on the
  outstanding Exchange Notes on the stated maturity or on the applicable
  redemption date, as the case may be, and the Authority must specify whether
  the Exchange Notes are being defeased to maturity or to a particular
  redemption date;
 
     (2) in the case of Legal Defeasance, the Authority shall have delivered
  to the Trustees an opinion of counsel in the United States reasonably
  acceptable to the Trustees confirming that
 
       (a) the Authority has received from, or there has been published by,
    the Internal Revenue Service a ruling; or
 
                                      107
<PAGE>
 
       (b) since the date of the Indentures, there has been a change in the
    applicable federal income tax law, in either case to the effect that,
    and based thereon such opinion of counsel shall confirm that, the
    holders of the Exchange Notes will not recognize income, gain or loss
    for federal income tax purposes as a result of such Legal Defeasance
    and will be subject to federal income tax on the same amounts, in the
    same manner and at the same times as would have been the case if such
    Legal Defeasance had not occurred;
 
     (3) in the case of Covenant Defeasance, the Authority shall have
  delivered to the Trustees an opinion of counsel in the United States
  reasonably acceptable to the Trustees confirming that the holders of the
  Exchange Notes will not recognize income, gain or loss for federal income
  tax purposes as a result of such Covenant Defeasance and will be subject to
  federal income tax on the same amounts, in the same manner and at the same
  times as would have been the case if such Covenant Defeasance had not
  occurred;
 
     (4) no Default or Event of Default shall have occurred and be continuing
  on the date of such deposit (other than a Default or Event of Default
  resulting from the borrowing of funds to be applied to such deposit) or
  insofar as Events of Default from bankruptcy or insolvency events are
  concerned, at any time in the period ending on the 91st day after the date
  of deposit;
 
     (5) such Legal Defeasance or Covenant Defeasance will not result in a
  breach or violation of, or constitute a default under any material
  agreement or instrument (other than the Indentures) to which the Authority
  or any of the Authority's Restricted Subsidiaries is a party or by which
  the Authority or any of the Authority's Restricted Subsidiaries is bound;
 
     (6) the Authority must have delivered to the Trustees an opinion of
  counsel that after the 91st day following the deposit, the trust funds will
  not be subject to the effect of any applicable bankruptcy, insolvency,
  reorganization or similar laws affecting creditors' rights generally;
 
     (7) the Authority shall have delivered to the Trustees an Officers'
  Certificate stating that the deposit was not made by the Authority with the
  intent of preferring the holders of Exchange Notes over the other creditors
  of the Authority with the intent of defeating, hindering, delaying or
  defrauding creditors of the Authority or others; and
 
     (8) the Authority shall have delivered to the Trustees an Officers'
  Certificate and an opinion of counsel, each stating that all conditions
  precedent provided for relating to the Legal Defeasance or the Covenant
  Defeasance have been complied with.
 
 Amendment, Supplement and Waiver
 
   Except as provided in this section, the Authority, the Tribe and the Trustee
may amend or supplement the Exchange Notes with the consent of the holders of
at least a majority of the aggregate outstanding principal amount of each of
the Senior Exchange Notes or the Senior Subordinated Exchange Notes, as
applicable, provided that without the consent of each holder affected, an
amendment or waiver (with respect to any Exchange Notes held by a non-
consenting holder) may not
 
     (1) reduce the principal amount of Exchange Notes whose holders must
  consent to an amendment, supplement or waiver;
 
     (2) reduce the principal of or change the fixed maturity of any Exchange
  Note or alter the provisions with respect to the redemption of the Exchange
  Notes (other than provisions relating to the covenants described above
  under the captions "--Description of the Senior Exchange Notes--Repurchase
  at the Option of Holders" and "--Description of the Senior Subordinated
  Exchange Notes--Repurchase at the Option of Holders");
 
     (3) reduce the rate of or change the time for payment of interest on any
  Exchange Note;
 
                                      108
<PAGE>
 
     (4) waive a Default or Event of Default in the payment of principal of
  or premium, if any, or interest on the Exchange Notes (except a rescission
  of acceleration of the Exchange Notes by the holders of at least a majority
  in aggregate principal amount of the Exchange Notes and a waiver of the
  payment default that resulted from such acceleration);
 
     (5) make any Exchange Note payable in money other than that stated in
  the Exchange Notes;
 
     (6) make any change in the provisions of the Indentures relating to
  waivers of past Defaults or the rights of holders of Exchange Notes to
  receive payments of principal of or premium, if any, or interest on the
  Exchange Notes;
 
     (7) waive a redemption payment with respect to any Exchange Note (other
  than a payment required by one of the covenants described above under the
  captions "--Description of the Senior Exchange Notes--Repurchase at the
  Option of Holders" and "--Description of the Senior Subordinated Exchange
  Notes--Repurchase at the Option of Holders"); or
 
     (8) make any change in the preceding amendment and waiver provisions.
 
   Without the consent of holders of at least 66 2/3% of the aggregate
outstanding principal amount of each of the Senior Exchange Notes and the
Senior Subordinated Exchange Notes, as applicable, the Authority may not amend,
alter or waive the provisions shown in the sections entitled "--Description of
the Senior Exchange Notes--Repurchase at the Option of Holders--Change of
Control" and "--Description of the Senior Subordinated Exchange Notes--
Repurchase at the Option of Holders--Change of Control." In addition, any
amendment to the provisions of Article X of the Senior Subordinated Indenture
(which relate to subordination) will require the consent of holders of at least
75% in aggregate principal amount of Senior Subordinated Exchange Notes then
outstanding.
 
   Notwithstanding the foregoing, without the consent of any holder of Exchange
Notes, and provided that any required governmental approval to ensure the
enforceability of the Exchange Notes and the Indentures, including that of the
NIGC or the BIA, is obtained, the Authority and the Trustee may amend or
supplement the Indentures or the Exchange Notes to
 
     (1) cure any ambiguity, defect or inconsistency;
 
     (2) provide for uncertificated Exchange Notes in addition to or in place

  to the holders of Exchange Notes or that does not adversely affect the
  legal rights under the Indentures of any such holder; or
 
     (5) comply with requirements of the Commission to effect or maintain the
  qualification of the Indentures under the Trust Indenture Act.
 
 Concerning the Trustees
 
   If a Trustee becomes a creditor of the Authority or any Guarantor, the
Indentures limit its right to obtain payment of claims in certain cases, or to
realize on certain property received in respect of any such claim as security
or otherwise. Such Trustee will be permitted to engage in other transactions;
however, if it acquires any conflicting interest it must eliminate such
conflict within 90 days, apply to the Commission for permission to continue or
resign.

   The holders of a majority in principal amount of the then outstanding
Exchange Notes will have the right to direct the time, method and place of
conducting any proceeding for exercising any remedy available to a Trustee,
subject to certain exceptions. The Indentures provide that in case an Event of
Default shall occur and be continuing, the Trustees will be required, in the
exercise of their power, to use the degree of care of a prudent man in the
conduct of his own affairs. Subject to such provisions, the Trustees will be
under no obligation to exercise any of their rights or powers under the
Indentures at the request of any holder of Exchange Notes, unless such holder
shall have offered to the Trustees security and indemnity satisfactory to each
of them against any loss, liability or expense.
 
 Governing Law
 
   The Indentures and the Notes will be, subject to certain exceptions,
governed by and construed in accordance with the internal laws of the State of
New York, without giving effect to the conflicts of law principles thereof
(other than Section 5-1401 of the New York General Obligations Law).

 Book-Entry, Delivery and Form
 
   The Exchange Notes will initially be issued in registered, global form in
minimum denominations of $1,000 and integral multiples of $1,000 in excess
thereof, held in book-entry form. The Exchange Notes will be deposited with the
Trustees as custodian for The Depository Trust Authority ("DTC"), and DTC or
its nominee will initially be the sole registered holder of the Exchange Notes
for all purposes under the Indentures. Except as shown below, the Global Senior
Notes (as defined in the Senior Indenture) and Global Senior Subordinated Notes
(as defined in the Senior Subordinated Notes Indenture), (collectively, the
"Global Notes") may be transferred, in whole and not in part, only to another
nominee of DTC or to a successor of DTC or its nominee.
 
   The Global Notes will be deposited upon issuance with the respective Trustee
as custodian for The Depository Trust Authority ("DTC"), in New York, New York,
and registered in the name of DTC or its nominee, in each case for credit to an
account of a direct or indirect participant in DTC as described below.
 
   Beneficial interests in the Global Notes may not be exchanged for Exchange
Notes in certificated form except in the limited circumstances described below.
See "--Exchange of Books-Entry Notes for Certificated Notes." Except in the
limited circumstances described below, owners of beneficial interests in the
Global Notes will not be entitled to receive physical delivery of the
Certificated Notes (as defined below).
 
   Initially, the Trustees will act as Paying Agent and Registrar. The Exchange
Notes may be presented for registration of transfer and exchange at the offices
of the Registrar.
 
 Depository Procedures
 
   The following description of the operations and procedures of DTC are
provided solely as a matter of convenience. These operations and procedures are
solely within the control of the respective settlement systems and are subject
to changes by them from time to time. The Authority takes no responsibility for
these operations and procedures and urges investors to contact the system or
their participants directly to discuss these matters.
 
                                      110
<PAGE>
 
   DTC has advised the Authority that DTC is a limited-purpose trust Authority
created to hold securities for its participating organizations (collectively,
the "Participants") and to facilitate the clearance and settlement of
transactions in those securities between Participants through electronic book-
entry changes in accounts of its Participants. The Participants include
securities brokers and dealers (including the Initial Purchasers), banks, trust
companies, clearing corporations and certain other organizations. Access to
DTC's system is also available to other entities such as banks, brokers,
dealers and trust companies that clear through or maintain a custodial
relationship with a Participant, either directly or indirectly (collectively,
the Indirect Participants"). Persons who are not Participants may beneficially
own securities held by or on behalf of DTC only through the Participants or the
Indirect Participants. The ownership interests in, and transfers of ownership
interests in, each security held by or on behalf of DTC are recorded on the
records of the Participants and Indirect Participants.
 
   DTC has also advised the Authority that, pursuant to procedures established
by it, (i) upon deposit of the Global Notes, DTC will credit the accounts of
Participants designated by the Initial Purchasers with portions of the
principal amounts of the Global Notes and (ii) ownership of such interests in
the Global Notes will be shown on, and the transfer of ownership thereof will
be effected only through, records maintained by DTC (with respect to the
Participants) or by the Participants and the Indirect Participants (with
respect to other owners of beneficial interest in the Global Notes).
 
   All interests in a Global Note, may be subject to the procedures and
requirements of DTC. The laws of some states require that certain persons take
physical delivery in definitive form of securities that they own. Consequently,
the ability to transfer beneficial interests in Global Note to such persons
will be limited to that extent. Because DTC can act only on behalf of
Participants, which in turn act on behalf of Indirect Participants and certain
banks, the ability of a person having beneficial interests in a Global Note to
pledge such interests to persons or entities that do not participate in the DTC
system, or otherwise take actions in respect of such interests, may be affected
by the lack of a physical certificate evidencing such interests.
 
   Except as described below, owners of interest in the Global Notes will not
have Exchange Notes registered in their names, will not receive physical
delivery of Exchange Notes in certificated form and will not be considered the
registered owners or "holders" thereof under the Indentures for any purpose.
 
   Payments in respect of the principal of, and premium, if any Additional
Interest, if any, and interest on a Global Note registered in the name of DTC
or its nominee will be payable to DTC in its capacity as the registered holder
under the Indentures. Under the terms of the Indentures, the Authority and the
Trustees will treat the persons in whose names the Exchange Notes, including
the Global Notes are registered as the owners thereof for the purpose of
receiving such payments and for any and all other purposes whatsoever.
Consequently, neither the Authority, the Trustees nor any agent of the
Authority or the Trustees has or will have any responsibility or liability for
(i) any aspect of DTC's records or any Participant's or Indirect participant's
records relating to or payments made on account of beneficial ownership
interests in the Global Notes, or for maintaining, supervising or reviewing any
of DTC's records or any Participant's or Indirect Participant's records
relating to the beneficial ownership interests in the Global Notes or (ii) any
other matter relating to the actions and practices of DTC or any of its
Participants or Indirect Participants. DTC has advise the Authority that its
current practice, upon receipt of any payment in respect of securities such as
the Notes (including principal and interests), is to credit the accounts of the
relevent Participants with the payment on the payment date, in amounts
proportionate to their respective holdings in the principal amount of the
beneficial interest in the relevent security as shown on the records of DTC
unless DTC has reason to believe it will not receive payment on such payment
date. Payments by the Participants and the Indirect Participants to the
beneficial owners of the Exchange Notes will be governed by standing
instructions and customary practices and will be the responsibility of the
Participants or the Indirect Participants and will not be the responsibility of
the DTC, the Trustees or the Authority. Neither the Authority nor the Trustees
will be liable for any delay by DTC or any of its Participants in identifying
the beneficial owners of the Exchange Notes, and the Authority and the Trustees
may conclusively rely on and will be protected in relying on instructions from
DTC or its nominee for all purposes.
 
                                      111

   Interest in the Global Notes are expected to be eligible to trade DTC's
Same-Day Funds Settlement System and secondary market trading activity in such
interests will, therefor, settle in immediately available funds, subject in all
cases to the rules and procedures of DTC and its Participants. See "--Same Day
Settlement and payment."
 
   Subject to the transfer restrictions shown under "Notice to Investors, "
transfers between Participants in DTC will be effected in accordance with DTC's
procedures, and will be settled in same day funds.
 
   DTC has advised the Authority that it will take any action permitted to be
taken by a holder of Exchange Notes only at the direction of one or more
Participants to whose account DTC has credited the interests in the Global
Notes and only in respect of such portion of the aggregate principal amount of
the Exchange Notes as to which such Participant or Participants has or have
given such direction. However, if there is an Event of Default under the
Exchange Notes, DTC reserves the right to exchange the Global Notes for
legended Exchange Notes in certificated form, and to distribute such Exchange
Notes to its Participants.
 
 Exchange of Book-Entry Exchange Notes for Certificated Notes
 
   A Global Note is exchangeable for definitive Exchange Notes in registered
certificated form ("Certificated Notes") if (i) DTC (x) notifies the Authority
that it is unwilling or unable to continue as depositary for the Global Notes
and the Authority thereupon fails to appoint a successor depositary or (y) has
ceased to be a clearing agency registered under the Exchange Act, (ii) the
Authority, at its option, notifies the applicable Trustee in writing that it
elects to cause the issuance of the Certificated Notes or (iii) there shall
have occurred and be continuing a Default or Event of Default with respect to
the Exchange Notes. In addition, beneficial interests in a Global Note may be
exchanged for Certificated Notes upon request but only upon prior written
notice given to the applicable Trustee by or on behalf of DTC in accordance
with the Indentures. In all cases, Certificated Notes delivered in exchange for
any Global Note or beneficial interests therein will be registered in the
names, and issued in any approved denominations, requested by or on behalf of
the depositary (in accordance with its customary procedures) and will bear the
applicable restrictive legend referred to in "Notice to Investors," unless the
Authority determines otherwise in compliance with applicable law.
 
 Exchange of Certificated Exchange Notes for Book-Entry Notes
 
   Exchange Notes in certificated form may not be exchanged for beneficial
interests in any Global Note unless the transferor first delivers to the
applicable Trustee a written certificate (in the form provided in the
Indentures) to the effect that such transfer will comply with the appropriate
transfer restrictions applicable to such Exchange Notes. See "Notice to
Investors."
 
 Same Day Settlement and Payment
 
   The Indentures require that payments in respect of the Exchange Notes
represented by the Global Notes (including principal, premium, if any, interest
and Additional Interest, if any) be made by wire transfer of immediately
available funds to the accounts specified by the Global Note holder. With
respect to Exchange Notes in certificated form, the Authority will make all
payments of principal, premium, if any, interest and Additional Interest, if
any, by wire transfer of immediately available funds to the accounts specified
by the holders thereof that holds at least $1.0 million in principal amount of
Exchange Notes or, if no such account is specified, by mailing a check to each
such holder's registered address.
 
 Registration Rights; Additional Interest
 
   The Authority and the Initial Purchasers entered into registration rights
agreements, pursuant to which, the Authority is filing with the Commission this
Exchange Offer Registration Statement under the Securities Act with respect to
the Exchange Notes. Upon the effectiveness of the Exchange Offer Registration
Statement, the Authority will offer to the holders of Transfer Restricted
Securities pursuant to the Exchange Offers who are
 
                                      112
<PAGE>
 
able to make certain representations the opportunity to exchange their Transfer
Restricted Securities for Exchange Notes. If (i) the Authority is not required
to file the Exchange Offer Registration Statement or permitted to consummate an
Exchange Offer because such Exchange Offer is not permitted by applicable law
or Commission policy or (ii) any holder of Transfer Restricted Securities
notifies the Authority before the 20th day following consummation of an
Exchange Offer that (A) it is prohibited by law or Commission policy from
participating in such Exchange Offer or (B) that it may not resell the Exchange
Notes acquired by it in the Exchange Offers to the public without delivering a
prospectus and the prospectus contained in the Exchange Offer Registration
Statement is not appropriate or available for such resales or (C) that it is a
broker-dealer and owns Outstanding Notes acquired directly from the Authority
or an affiliate of the Authority, the Authority will file with the Commission a
Shelf Registration Statement to cover resales of the Outstanding Notes by the
holders thereof who satisfy certain conditions relating to the provision of
information in connection with the Shelf Registration Statement. The Authority
will use its best efforts to cause the applicable registration statement to be
declared effective as promptly as possible by the Commission. For purposes of
the foregoing, "Transfer Restricted Securities" means each Outstanding Note
until (i) the date on which such Outstanding Note has been exchanged by a
person other than a broker-dealer for an Exchange Note in the Exchange Offers,
(ii) following the exchange by a broker-dealer in an Exchange Offer of an
Outstanding Note for a Exchange Note, the date on which such Exchange Note is
sold to a purchaser who receives from such broker-dealer on or before the date
of such sale a copy of the prospectus contained in the Exchange Offer
Registration Statement, (iii) the date on which such Note has been effectively
registered under the Securities Act and disposed of in accordance with the
Shelf Registration Statement or (iv) the date on which such Note is distributed
to the public pursuant to Rule 144 under the Act.
 
   The registration rights agreements each provide that (i) the Authority will
file an Exchange Offer Registration Statement with the Commission on or before
90 days after the Closing Date, (ii) the Authority will use its best efforts to
have the Exchange Offer Registration Statement declared effective by the
Commission on or before 150 days after the Closing Date, (iii) unless the
Exchange Offers would not be permitted by applicable law or Commission policy,
the Authority will commence the Exchange Offers and use its best efforts to
issue on or before 30 business days after the date on which the Exchange Offer
Registration Statement was declared effective by the Commission, Exchange Notes
in exchange for all Outstanding Notes tendered prior thereto in the Exchange
Offers and (iv) if obligated to file the Shelf Registration Statement, the
Authority will use its best efforts to file the Shelf Registration Statement
with the Commission on or before 30 days after such filing obligation arises
and to cause the Shelf Registration to be declared effective by the Commission
on or before 90 days after such obligation arises. If (a) the Authority fails
to file any of the Registration Statements required by the registration rights
agreements on or before the date specified for such filing, (b) any of such
Registration Statements is not declared effective by the Commission on or
before the date specified for such effectiveness (the "Effectiveness Target
Date"), or (c) the Authority fails to consummate the Exchange Offers within
30 business days of the Effectiveness Target Date with respect to the Exchange
Offer Registration Statement, or (d) the Shelf Registration Statement or the
Exchange Offer Registration Statement is declared effective but thereafter
ceases to be effective or usable in connection with resales of Transfer
Restricted Securities during the periods specified in the registration rights
agreements (each such event referred to in clauses (a) through (d) above a
"Registration Default"), then the Authority will pay Additional Interest to
each holder of Notes, with respect to the first 90-day period immediately
following the occurrence of the first Registration Default in an amount equal
to 25 basis points per 90-day period of the principal amount of Notes held by
such holder. The amount of the Additional Interest will increase by an
additional 25 basis points with respect to each subsequent 90-day period until
all Registration Defaults have been cured, up to a maximum amount of Additional
Interest of 1% per annum of the principal amount of Notes. All accrued
Additional Interest will be paid by the Authority on each date on which the
payment of Additional Interest is due (which date shall be the next Interest
Payment Date as provided in the Notes) to the Global Note holder by wire
transfer of immediately available funds or by federal funds check and to
holders of Certificated Securities by wire transfer to the accounts specified
by them or by mailing checks to their registered addresses if no such accounts
have been specified. Following the cure of all Registration Defaults, the
accrual of Additional Interest will cease.
 
                                      113

   Holders of Outstanding Notes will be required to make certain
representations to the Authority (as described in the registration rights
agreement) to participate in the Exchange Offers and will be required to
deliver information to be used in connection with the Shelf Registration
Statement and to provide comments on the Shelf Registration Statement within
the time periods shown in the registration rights agreements to have their
Outstanding Notes included in the Shelf Registration Statement and benefit from

                              PLAN OF DISTRIBUTION
 
   Each broker-dealer that receives Exchange Notes for its own account pursuant
to the Exchange Offers must acknowledge that it will deliver a prospectus in
connection with any resale of such Exchange Notes. This Prospectus, as it may
be amended or supplemented from time to time, may be used by a broker-dealer in
connection with resales of Exchange Notes received in exchange for Outstanding
Notes where such Outstanding Notes were acquired as a result of market-making
activities or other trading activities. The Authority has agreed that, starting
on the Expiration Date and ending on the close of business on the first
anniversary of the Expiration Date, it will make this Prospectus, as amended or
supplemented, available to any broker-dealer for use in connection with any
such resale.
 
   The Authority will not receive any proceeds from any sale or Exchange Notes
by broker-dealers. Exchange Notes received by broker-dealers for their own
accounts pursuant to the Exchange Offers may be sold from time to time in one
or more transactions in the over-the-counter market, in negotiated
transactions, through the writing of options on the Exchange Notes or a
combination of such methods of resale, at market prices. Any such resale may be
made directly to purchasers or to or through brokers or dealers who may receive
compensation in the form of commissions or concessions from any such broker-
dealer and/or the purchasers of any such Exchange Notes. Any broker-dealer that
resells Exchange Notes that were received by it for its own account pursuant to
the Exchange Offers and any broker or dealer that participates in a
distribution of such Exchange Notes may be deemed to be an "underwriter" within
the meaning of the Securities Act and any profit of any such resale of Exchange
Notes and any commissions or concessions received by any such persons may be
deemed to be underwriting compensation under the Securities Act. The Letter of
Transmittal states that by acknowledging that it will deliver and by delivering
a prospectus, a broker-dealer will not be deemed to admit that it is an
"underwriter" within the meaning of the Securities Act.
 
   For a period of one year after the Expiration Date, the Authority will
promptly send additional copies of this Prospectus and any amendment or
supplement to this Prospectus to any broker-dealer that requests such documents
in the Letter of Transmittal. The Authority has agreed to pay all expenses
incident to the Exchange Offers (including the expenses of one counsel for the
holders of the Outstanding Notes), other than commissions or concessions of any
brokers or dealers, and will indemnify the holders of the Outstanding Notes
(including any broker-dealers) against certain liabilities, including
liabilities under the Securities Act.
 
                                 LEGAL MATTERS
 
   Certain legal matters with regard to the validity of the Exchange Notes will
be passed upon for the Authority by Hogan & Hartson L.L.P., Washington, D.C.
Latham & Watkins, New York, New York, has acted as counsel for the initial
purchasers of the Outstanding Notes.

Prospectus have been audited by Arthur Andersen LLP, independent auditors, as

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Mohegan Tribal Gaming Authority:
 
   We have audited the accompanying balance sheets of the Mohegan Tribal Gaming
Authority (the Authority) as of September 30, 1998 and 1997, and the related
statements of income (loss) and capital for the year ended September 30, 1998
and for the period October 12, 1996 (date of commencement of operations),
through September 30, 1997 and statements of cash flows for the years ended
September 30, 1998 and 1997. These financial statements are the responsibility
of the Authority's management. Our responsibility is to express an opinion on
these financial statements based on our audits.
 
   We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
   In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of the Mohegan Tribal Gaming
Authority as of September 30, 1998 and 1997, and the results of its operations
for the year ended September 30, 1998 and for the period October 12, 1996 (date
of commencement of operations), through September 30, 1997 and its cash flows
for the years ended September 30, 1998 and 1997, in conformity with generally
accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
 
                          SEPTEMBER 30, 1998 AND 1997
 
Note 1--Organization and 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 Tribe established the Authority with the exclusive power to
conduct and regulate gaming activities for the Tribe. Under the Indian Gaming
Regulatory Act of 1988, federally recognized Indian tribes are permitted to
conduct full-scale casino gaming operations on tribal land, subject to, among
other things, the negotiation of a tribal state compact with the affected
state. The Tribe and the State of Connecticut have entered into such a compact
(the "Mohegan Compact") that has been approved by the U.S. Secretary of the
Interior. On October 12, 1996, the Authority opened a casino known as Mohegan
Sun ("Mohegan Sun").
 
   The Authority is governed by a Management Board, which consists of the nine
members of the Tribal Council. The Management Board has engaged Trading Cove
Associates ("TCA"), a Connecticut general partnership, to manage the operation
of Mohegan Sun pursuant to a seven-year contract (the "Management Agreement").
TCA is 50% owned by Sun Cove Limited, an affiliate of Sun International Hotels
Limited ("Sun International"), and 50% owned by Waterford Gaming L.L.C. (See
Note 13 for discussion of Relinquishment Agreement between the Tribe and TCA).
 
Note 2--Summary of Significant Accounting Policies
 
 Management's Use of Estimates
 
   The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
 Cash and Cash Equivalents
 
   The Authority classifies as cash all highly liquid investments with a
maturity of three months or less when purchased. Cash equivalents are carried
at cost, which approximates market value.
 
 Inventories
 
   Inventories are stated at the lower of the cost or market value. Cost is
determined by using the first-in, first-out method.
 
 Property and Equipment
 
   Property and equipment are stated at cost. Depreciation is provided over the
estimated useful lives of the assets using the straight-line basis over the
estimated useful lives of the assets as follows:
 
<TABLE>
   <S>                                                                 <C>
   Buildings and land improvements....................................  40 years
   Furniture and equipment............................................ 3-7 years
</TABLE>
 
   The costs of significant improvements are capitalized. Costs of normal
repairs are charged to expense as incurred. Gains or losses on disposition of
property and equipment are included in the determination of income.
 
 Long-Lived Assets
 
   The Authority adopted the provisions of Statement of Financial Accounting
Standards No. 121 "Accounting for the Impairment of Long-Lived Assets," ("SFAS
121"). SFAS 121 requires, among other
 
                                      F-7

                   NOTES TO FINANCIAL STATEMENTS--(Continued)
 
things, that an entity review its long-lived assets and certain related
intangibles for impairment whenever changes in circumstances indicate that the
carrying amount of an asset may not be fully recoverable. As a result of its
review, the Authority does not believe that any asset impairment exists in the
recoverability of its long-lived assets as of September 30, 1998.
 
 Fair Value of Financial Instruments
 
   The fair value amounts disclosed below have been reported to meet the
disclosure requirements of SFAS No. 107, "Disclosures about Fair Values of
Financial Instruments" and are not necessarily indicative of the amounts that
the Authority could realize in a current market exchange.
 
   The carrying amount of cash and cash equivalents, receivables, accounts
payables and accrued expenses, and capital lease obligations approximate fair
value.
 
   At September 30, 1998, the fair value of the Authority's financing
facilities and related deferred interest ($31.5 million at September 30, 1998)
is as follows:

   Existing Secured Notes......................................... $207 million
   Junior Subordinated Notes...................................... $106 million
</TABLE>
 
 Revenue Recognition
 
   The Authority recognizes casino revenue as gaming wins less gaming losses.
Revenues from food and beverage, retail and special events are recognized at
the time the service is performed.
 
 Promotional Allowances
 
   The retail value of food and beverage and other services furnished to casino
guests without charge is included in gross revenue and then deducted as
promotional allowances.
 
   The estimated value of providing such promotional allowances was included in
revenues as follows (in thousands):

 Advertising

the advertising takes place, except for billboard advertising which is
capitalized and amortized over its expected period of future benefits. The
capitalized costs of the advertising are amortized over the terms of the

 Income Taxes
 
   The Tribe is an "Indian Tribal Government" within the meaning of sections
7701(a)(40) and 7871 of the Internal Revenue Code of 1986. As such, the
Authority has tax-exempt status with respect to federal and state income taxes.
 
 New Accounting Pronouncements
 
   In June 1997, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards No. 130 ("SFAS No. 130"),
"Reporting Comprehensive Income." This statement establishes standards for
reporting and displaying of comprehensive income and its components in the
financial statements. Adoption of SFAS No. 130 is required for fiscal years
beginning after December 15, 1997. Management believes the adoption of SFAS No.
130 will not have a material impact on the Authority's financial position or
results of operations.
 
   In June 1997, Statement of Financial Accounting Standards No. 131 ("SFAS No.
131"), "Disclosures about Segments of an Enterprise and Related Information"
was issued. This statement requires that public business enterprises report
certain information about operating segments in complete sets of financial
statements of the enterprise and in condensed financial statements of interim
periods issued to shareholders. It also requires that public business
enterprises report certain information about their products and services, the
geographic areas in which they operate, and their major customers. Adoption of
SFAS No. 131 is required for fiscal years beginning after December 15, 1997.
The Authority currently discloses financial data in accordance with existing
accounting and disclosure requirements. At the appropriate time the Authority
will modify its current presentation, if necessary, to meet the requirements of
SFAS No. 131. Management believes the adoption of SFAS No. 131 will have no
impact on the Authority's financial position or results of operations.
 
   In June 1998, Statement of Financial Accounting Standards No. 133 ("SFAS No.
133"), "Accounting for Derivative Instruments and Hedging Activities" was
issued. This statement revises the accounting for derivative financial
instruments. The Authority is currently analyzing the impacts of this statement
which management does not expect to have a material impact on the Authority's
financial position or results of operations.
 
   In April 1998, the American Institute of Certified Public Accountants
("AICPA") issued Statement of Position 98-5 ("SOP 98-5"), "Reporting on the
Costs of Start-Up Activities," which revises the accounting for start-up costs
and will require the expensing of certain costs which the Authority has
historically capitalized. The Authority is currently analyzing the impacts of
this statement, which is effective for fiscal years beginning after December
15, 1998. Management does not expect this statement to have a material impact
on the Authority's financial position or results of operations.
 
 Reclassifications
 
   Certain amounts in the 1997 financial statements have been reclassified to
conform with the 1998 presentation.
 
Note 3--Cash and Cash Equivalents
 
   At September 30, 1998 and 1997, the Authority had $5.3 million and $14.0
million, respectively invested in commercial paper. For reporting purposes,
cash equivalents include all operating cash as well as in-house funds.

 Replacement Reserve Fund
 
   Pursuant to terms of the Management Agreement, TCA is required to establish
a Replacement Reserve Fund, which may be used to pay any approved budgeted
capital expenditures. Any portion of the Replacement Reserve Fund which remains
unused at the end of any fiscal year will be carried forward to the following
year. TCA and the Tribe are each required to make monthly contributions to the
Replacement Reserve Fund at the rate of 60% from the Tribe and 40% from TCA up
to a combined total of $3.0 million per year from both parties. As of September
30, 1998 and 1997, the unused balance in the Replacement Reserve Fund totaled
$250,000 and $1.5 million, respectively.
 
 Cash Maintenance Account
 
   The Existing Secured Notes provide that the Authority shall deposit into the
Cash Maintenance Account, on a monthly basis, 1/2 of $6.0 million, for each
calendar year, plus any amounts deferred from any prior month, no later than 25
days after the end of such calendar month. As required under the Existing
Secured Notes, $10.0 million and $4.5 million have been deposited in the Cash
Maintenance Account as of September 30, 1998 and 1997, respectively.
 
 Interest and Excess Cash Flow Account
 
   The Existing Secured Notes provide that the Authority shall deposit into the
Interest and Excess Cash Flow Account, on a monthly basis, the amount of fixed
interest accrued during the prior month on the Senior Secured Notes, 50% of the
Excess Cash Flow (as defined) for the prior month on the Existing Secured
Notes, 100% of all Deferred Subordinated Interest for the prior month, and the
amount of Cash Flow Participation Interest accrued for the prior month. Amounts
deposited into the Interest and Excess Cash Flow Account are invested only in
cash or cash equivalents (See Note 8).
 
Note 5--Accounts Receivable
 
   The Authority maintains an allowance for doubtful accounts which is based on
management's estimate of the amount expected to be uncollectible considering
historical experience and the information management obtains regarding the
credit worthiness of the customer. The collectibility of these receivables
could be affected by future business or economic trends. Although management
believes the allowance is adequate, it is possible that the estimated amount of
cash collections could change.
 
   At September 30, 1998 and 1997, the Authority established $348,000 and
$187,000, respectively in allowance for doubtful accounts.

13.50% per annum and Cash Flow Participation Interest, as defined therein, in
an aggregate amount of 5.0% of the Authority's Cash Flow up to, during any two
consecutive semi-annual periods, ending September 30, $250 million of the

                   NOTES TO FINANCIAL STATEMENTS--(Continued)
 
Participation Interest payable will be reduced pro rata for reductions in
outstanding principal amount of Existing Secured Notes. The payment of Cash
Flow Participation Interest may be deferred if the Authority's Fixed Charge
Coverage Ratio, as defined, is less than 2.0 to 1.0. For the year ended
September 30, 1998 and for the period from October 12, 1996 (date of
commencement of operations) through September 30, 1997, the Authority's Fixed
Charge Coverage Ratio was 4.0 and 3.0 respectively. The Existing Secured Notes
are redeemable at set prices as set forth in the Existing Secured Notes after
November 15, 1999, at the option of the Authority. Upon the occurrence of
certain events (as specified in the Existing Secured Notes) each holder of
Existing Secured Notes can require the Authority to repurchase the notes at
prices specified.
 
   Beginning with the fiscal year ending September 30, 1997, the Authority is
required within 120 days, under certain circumstances, to offer to purchase, at
set prices, certain amounts of Existing Secured Notes then outstanding, under
the Excess Cash Purchase Offer, as defined in the Existing Secured Notes (See
Excess Cash Purchase Offer below).
 
 Subordinated Notes
 
   The Authority has obtained $90.0 million of subordinated financing from Sun
International and Waterford Gaming L.L.C. in the form of notes ("Junior
Subordinated Notes"). The Authority has issued $20.0 million of Junior
Subordinated Notes to each of Sun International and Waterford Gaming L.L.C.,
which notes bear interest at 15.0% per year. The Authority also has issued
$50.0 million of Junior Subordinated Notes to Sun International evidencing
draws made by the Authority under the secured completion guarantee provided by
Sun International ("Secured Completion Guarantee"). Each Junior Subordinated
Note issued under the Secured Completion Guarantee bears interest at the rate
per annum then most recently announced by Chase Manhattan Bank (f/k/a Chemical
Bank of New York) as its prime rate plus 1% which shall be set and revised at
intervals of six months. The interest rates were 9.5% at September 30, 1998 and
September 30, 1997. Interest on the Junior Subordinated Notes is payable semi-
annually, provided, however that all such interest is deferred and will not be
paid until at least half of the Existing Secured Notes have been offered to be
repurchased or retired, pursuant to the terms of the Existing Secured Notes,
and certain other conditions have been fulfilled. Accrued and deferred interest
payable on the Junior Subordinated Notes is $31.5 million and $17.9 million at
September 30, 1998 and 1997, respectively. All Junior Subordinated Notes are
due 2003; however, principal cannot be paid until the Existing Secured Notes
have been paid in full, unless certain conditions are met. During October 1998
and October 1997, a total of $5.0 million of Junior Subordinated Notes issued
to Sun International pursuant to the Secured Completion Guarantee were
purchased by Waterford Gaming L.L.C.
 
   In the event that the holders of the Existing Secured Notes reject all or
any portion of the Excess Cash Purchase Offer, as defined in the Existing
Secured Notes Indenture, the Authority is required to offer to purchase, at
par, certain amounts of the Junior Subordinated Notes then outstanding. See
Excess Cash Purchase Offer below for such offer made by the Authority.
 
 Excess Cash Purchase Offer
 
   Pursuant to the Existing Secured Notes, the Authority is required to make an
Excess Cash Purchase Offer to all holders of the Existing Secured Notes within
120 days after each fiscal year end of the Authority, commencing September 30,
1997. The Excess Cash Purchase Offer equals 50% of the Excess Cash Flow, as
defined, plus 100% of the Deferred Subordinated Interest.
 
   An Excess Cash Purchase Offer of $29.1 million was made on January 28, 1998
for the period October 12, 1996 (date of commencement of operations) through
September 30, 1997. In accordance with the Existing Secured Notes Indenture,
the Authority offered to purchase the Existing Secured Notes at 113.5% of the

agreement, an offer to repurchase in the amount of the Excess Cash Purchase
Offer was made to the holders of the Junior Subordinated Notes. The offer
period concluded on April 2, 1998, and the holders of the Junior Subordinated
Notes also rejected the offer. On April 3, 1998, as permitted by the Existing
Secured Notes Indenture, the Authority distributed the Excess Cash Purchase
Offer of $29.1 million to the Tribe. The Authority will make an Excess Cash
Purchase Offer to all holders of the Existing Secured Notes within 120 days of

defined in Section 414(q) of the Internal Revenue Code, to defer up to 100% of
their income to the plan. As of September 30, 1998 there have been no
contributions by eligible employees to this plan.
 
Note 12--Commitments and Contingencies
 
 The Mohegan Compact
 
   The Mohegan Compact stipulates that a portion of the revenues earned on slot
machines must be paid to the State of Connecticut ("Slot Win Contribution").
For each 12-month period commencing July 1, 1995, the Slot Win Contribution
shall be the lesser of (a) 30% of gross revenues from slot machines, or (b) the
greater of (i) 25% of gross revenues from slot machines or (ii) $80 million.
 
   The Slot Win Contribution payments will not be required if the State of
Connecticut legalizes any other (except those consented to by the Mashantucket
Pequot Tribe and Mohegan Tribe) gaming operations with slot machines or other
commercial casino table games within Connecticut. The Authority has reflected
$102.3 million and $80.7 million, respectively of gaming expense in its
financial statements for the required Slot Win Contribution for the year ended
September 30, 1998 and for the period from October 12, 1996 (date of
commencement of operations) through September 30, 1997.
 
 Town of Montville Agreement
 
   On June 16, 1994, the Tribe and the Town of Montville (the "Town") entered
into an agreement whereby the Tribe agreed to pay to the Town an annual payment
of $500,000 to minimize the impact to the Town

resulting from decreased tax revenues on reservation land held in trust. Two
annual $500,000 payments payable beginning one year after the commencement of
slot machine gaming activities, were remitted to the Town of Montville in
October 1998 and 1997, respectively. Additionally, the Tribe agreed to make a
one-time payment of $3.0 million towards infrastructure improvements to the
Town's water system. The Tribe has assigned its rights and obligations in this
agreement to the Authority. The Town is billing the Authority for the
infrastructure improvements as the Town's costs are incurred. As of September
30, 1998, the Authority has paid $1.1 million to the Town of Montville towards
improvements to the municipal water system, which has been included in other
assets in the accompanying balance sheet and will be amortized over 40 years.
 
 Litigation
 
   The Authority is a defendant in certain litigation incurred in the normal
course of business. In the opinion of management, based on the advice of
counsel, the aggregate liability, if any, arising from such litigation will not
have a material adverse effect on the Authority's financial position or results
of operations.
 
Note 13--TCA Agreements
 
 Management Agreement
 
   The Tribe and TCA entered into the Amended and Restated Gaming Facility
Management Agreement (the "Management Agreement"), pursuant to which the Tribe
has retained and engaged TCA, on an independent contractor basis, to operate,
manage and market Mohegan Sun.
 
   The Tribe has assigned its rights and obligations under the Management
Agreement to the Authority. The term of the Management Agreement is seven
years. TCA holds responsibility to manage Mohegan Sun in exchange for payments
ranging from 30% to 40% of net income, before management fees, as defined,
depending upon profitability levels. Management fees totaled $47.4 million and
$23.2 million, respectively, for the year ended September 30, 1998 and for the
period ended September 30, 1997. As of September 30, 1998, $4.1 million was
owed to TCA in connection with the Management Agreement.
 
 Relinquishment Agreement
 
   In February 1998, the Authority and TCA entered into an agreement, (the
"Relinquishment Agreement"). The Relinquishment Agreement supersedes the
Management Agreement effective the later of January 1, 2000 (the
"Relinquishment Date"), or the date the existing Existing Secured Notes are
refinanced or repaid, and provides that the Authority shall make certain
payments to TCA out of, and determined as a percentage of, the gross revenues
generated by Mohegan Sun over a 15-year period commencing on the Relinquishment
Date. The payments ("Senior Relinquishment Payments" and the "Junior
Relinquishment Payments"), each of which are calculated as 2.5% of revenues, as
defined, have their own payment schedule and priority. Senior Relinquishment
Payments commence at the end of the first three-month period following the
Relinquishment Date and continue at the end of each three-month period
occurring thereafter until the fifteenth anniversary of the Relinquishment
Date. Junior Relinquishment Payments commence at the end of the first six-month
period following the Relinquishment Date and continue at the end of each six-
month period occurring thereafter until the fifteenth anniversary of the
Relinquishment Date. Each Senior Relinquishment Payment and Junior
Relinquishment Payment is an amount equal to 2.5% of the Revenues generated by
Mohegan Sun over the immediately preceding three-month or six-month payment
period, as the case may be. "Revenues" are defined as gross gaming revenues
(other than Class II gaming revenue) and all other facility revenues
(including, without limitation, hotel revenues, fees or receipts from
convention/events center in the expansion and all rental or other receipts from
lessees and concessionaires operating in the facility but not the gross
receipts of such

lessees, licenses and concessionaires). The Authority, in accordance with
Financial Accounting Standards Board Statement No. 5, "Accounting for
Contingencies", has recorded a relinquishment liability of the estimated
present value of its obligations under the Relinquishment Agreement. The
liability was estimated at $549.1 million as of September 30, 1998 and will be
reassessed periodically. This amount was derived by discounting the present
value of 5% of projected gross revenues by the Authority's risk free investment
rate. The Authority has also recognized the value of the trademarks associated
with the Mohegan Sun brand name as of the September 30, 1998. The Mohegan Sun
trademarks, which were appraised by an independent consultant, are valued at
$130.0 million. TCA's services will be retained, however, in the development
and construction of the Phase II expansion (See "Development Agreement").
 
 Development Agreement
 
   The Authority has also negotiated a second agreement with TCA (the
"Development Agreement"), which will make TCA the exclusive developer of the
planned expansion of Mohegan Sun. Under the Development Agreement, TCA will
oversee the planning, design and construction of the expansion of Mohegan Sun
and will receive compensation of $14 million for such services.
 
Note 14--Extraordinary Items
 
   The Authority incurred $419.5 million of extraordinary items for the year
ended September 30, 1998. Included in the expense is $332,000 related to the
early extinguishment of debt and $419.1 million related to the Relinquishment
Agreement discussed in Note 13.
 
Note 15--Subsequent Events
 
   On December 7, 1998, the Authority opened a 4,000 square foot gas station
facility. The facility consists of 16 gasoline pumps, one diesel fuel pump, and
a convenience store that offers fresh baked goods and retail items. The cost of
the facility was approximately $5.9 million and is being financed through
equipment leasing and internally generated funds.
 
   On December 23, 1998, the Authority borrowed the final $878,000 available in
equipment financing from CIT Group at an interest rate of 7.75% over 48 months.
 
   The Tribe has announced an expansion of Mohegan Sun consisting of 100,000
square feet of additional gaming space, a luxury hotel with approximately 1,500
rooms, a convention/events center with seating for 10,000 patrons and 100,000
square feet of convention space. The expansion is estimated to cost $750
million (excluding capitalized interest and excluding a $50 million project
contingency). The Tribe has chosen a site master planning firm, an architect
and a project developer for the expansion. In connection with the expansion,
the Existing Secured Notes and Junior Subordinated Notes will be refinanced. It
is anticipated that a loss on the extinguishment of the Existing Secured Notes
and Junior Subordinated Notes will be reflected in the Authority's second
quarter financial statements for fiscal 1999.
 
   Effective January 1, 1999, the Authority will change the employer
contribution match of its retirement savings plan to 100% of eligible employee
contributions up to a maximum of 3% of their individual earnings. This
retirement savings plan as discussed in Note 11, is pursuant to Section 401 of
the Internal Revenue Code.

                REVIEW REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Mohegan Tribal Gaming Authority:
 
   We have reviewed the accompanying balance sheet of the Mohegan Tribal Gaming
Authority (the Authority) as of December 31, 1998, and the related statements
of income, capital and cash flows for the three-month periods ended December
31, 1998 and 1997. These 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 balance sheets of the Mohegan Tribal Gaming Authority as of
September 30, 1998 and 1997, and the related statements of income (loss) and
capital for the year ended September 30, 1998 and for the period October 12,
1996 (date of commencement of operations) through September 30, 1997 (not
presented herein) and statements of cash flows for the years ended September
30, 1998 and 1997 (not presented herein) and in our report dated December 21,
1998, we expressed an unqualified opinion on those financial statements. In our
opinion, the information set forth in the accompanying balance sheet of the
Mohegan Tribal Gaming Authority as of September 30, 1998, is fairly stated, in
all material respects, in relation to the balance sheet from which it has been
derived.

                                  (Unaudited)
 
1. 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 Tribe established the Authority with the exclusive power to
conduct and regulate gaming activities for the Tribe. Under the Indian Gaming
Regulatory Act of 1988, federally recognized Indian tribes are permitted to
conduct full-scale casino gaming operations on tribal land, subject to, among
other things, the negotiation of a tribal state compact with the affected
state. The Tribe and the State of Connecticut have entered into such a compact
(the "Mohegan Compact") that has been approved by the Secretary of the
Interior. On October 12, 1996, the Authority opened a casino known as Mohegan
Sun Casino ("Mohegan Sun").
 
   The Authority is governed by a Management Board, which consists of the nine
members of the Tribal Council. The Management Board has engaged Trading Cove
Associates ("TCA"), a Connecticut general partnership, to manage the operation
of Mohegan Sun pursuant to a seven year contract (the "Management Agreement").
TCA is 50% owned by Sun Cove Limited, an affiliate of Sun International Hotels
Limited ("Sun International"), and 50% owned by Waterford Gaming L.L.C. (See
Note 6 for discussion of Relinquishment Agreement between the Tribe and TCA).
 
   The accompanying financial statements have been prepared in accordance with
the accounting policies described in the Authority's 1998 Annual Report on Form
10-K and should be read in conjunction with the Notes to Financial Statements
which appear in that report. The Balance Sheet at September 30, 1998, contained
herein, was taken from the audited financial statements, but does not include
all disclosures contained in the Form 10-K and required by generally accepted
accounting principles.
 
   Certain amounts in the financial statements have been reclassified. The
reclassification has no effect on the Authority's 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 financial
statements for the quarter ended December 31, 1998 are not necessarily
indicative of expected results for the full year, as the casino industry in
Connecticut is seasonal in nature.
 
2. Financing Facilities:
 
 Line of Credit
 
   The Authority has a $2.5 million line-of-credit and letter of credit
arrangement with Fleet National Bank. Interest is payable at the bank's base
rate or LIBOR option. Borrowings are collateralized by a security interest in
all of the Authority's cash deposit accounts with Fleet National Bank. This
arrangement expires on March 31, 2000. As of December 31, 1998, the Authority
has issued letters of credit of $1.9 million and has no borrowings outstanding
under the line-of-credit.
 
   Financing facilities, as described below, consisted of the following (in
thousands):

                               December 31, 1998
                                  (Unaudited)
 Existing Secured Notes
 
   On September 29, 1995, the Authority issued $175 million in senior secured
notes (the "Existing Secured Notes") with fixed interest payable at a rate of
13.5% per annum and Cash Flow Participation Interest, as defined therein, in an
aggregate amount of 5% of the Authority's Cash Flow up to, during any two
consecutive semi-annual periods, ending September 30, $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 the outstanding principal amount of
Existing Secured Notes. The payment of Cash Flow Participation Interest may be
deferred if the Authority's Fixed Charge Coverage Ratio, as defined, is less
than 2.0. For the quarters ended December 31, 1998 and 1997, the Authority's
Fixed Charge Coverage Ratio was 4.0 and 3.0, respectively. The Existing Secured
Notes are redeemable at set prices set forth in the Existing Secured Notes,
after November 15, 1999, at the option of the Authority (see Note 8 for a
discussion of the tender offer and consent solicitation). Upon the occurrence
of certain events (as specified in the Existing Secured Notes) each holder of
Existing Secured Notes can require the Authority to repurchase the notes at
prices specified.
 
   Beginning with the fiscal year ended September 30, 1997, the Authority was
required within 120 days, under certain circumstances, to offer to purchase, at
set prices, certain amounts of Existing Secured Notes then outstanding, under
the Excess Cash Purchase Offer, as defined in the Existing Secured Notes. See
"Excess Cash Purchase Offer" below.
 
 Junior Subordinated Notes
 
   The Authority has obtained $90 million of subordinated financing from Sun
International and Waterford Gaming L.L.C. in the form of notes ("Junior
Subordinated Notes"). The Authority has issued $20 million of Junior
Subordinated Notes to each of Sun International and Waterford Gaming L.L.C.,
which notes bear interest at 15% per year. The Authority also has issued $50
million in Junior Subordinated Notes to Sun International evidencing draws made
by the Authority under the secured completion guarantee provided by Sun
International ("Secured Completion Guarantee"). Each Junior Subordinated Note
issued under the Secured Completion Guarantee bears interest at the rate per
annum then most recently announced by the Chase Manhattan Bank (f/k/a Chemical
Bank of New York) as its prime rate plus 1%, which shall be set and revised at
intervals of six months. The interest rates were 8.75% and 9.5% at December 31,
1998 and 1997, respectively. Interest on the Junior Subordinated Notes is
payable semi-annually, provided, however that all such interest is deferred and
will not be paid until at least half of the Existing Secured Notes have been
offered to be repurchased or retired, pursuant to the terms of the Existing
Secured Notes, and certain other conditions have been fulfilled. Accrued and
deferred interest payable on the Junior Subordinated Notes was $35.2 million
and $21.2 million as of December 31, 1998 and 1997, respectively. All Junior
Subordinated Notes are due 2003; however, principal cannot be paid until the
Existing Secured Notes have been paid in full, unless certain conditions are
met. During October 1998 and October 1997, a total of $5.0 million of Junior
Subordinated Notes, issued to Sun International pursuant to the Secured
Completion Guarantee were purchased by Waterford Gaming L.L.C.
 
   In the event that the holders of the Existing Secured Notes reject all or
any portion of the Excess Cash Purchase Offer, as defined in the Existing
Secured Notes Indenture, the Authority is required to offer to purchase, at
par, certain amounts of the Junior Subordinated Notes then outstanding. See
"Excess Cash Purchase Offer" below.

                                  (Unaudited)
 
 Excess Cash Purchase Offer
 
   Pursuant to the Existing Secured Notes, the Authority is required to make an
Excess Cash Purchase Offer to all holders of the Existing Secured Notes within
120 days after each fiscal year end of the Authority, commencing September 30,
1997. The Excess Cash Purchase Offer equals 50% of the Excess Cash Flow, as
defined, plus 100% of the Deferred Subordinated Interest.
 
   An Excess Cash Purchase Offer of $51.2 million was made on December 30, 1998
for the year ended September 30, 1998. In accordance with the Existing Secured
Notes, the Authority offered to purchase the Existing Secured Notes at 112% of
the principal amount of the Existing Secured Notes plus accrued and unpaid
interest to the purchase date. The Excess Cash Purchase Offer expired, by its
terms, on January 29, 1999, and none of the holders of the Existing Secured
Notes accepted the offer.
 
   On February 1, 1999, pursuant to the Junior Subordinated Note purchase
agreement, an offer to repurchase in the amount of the Excess Cash Purchase
Offer was made to the holders of the Junior Subordinated Notes. On February 1,
1999, the holders of the Junior Subordinated Notes rejected the offer. On
February 2, 1999, as permitted by the Existing Secured Notes Indenture, the
Authority distributed the Excess Cash Purchase Offer of $51.2 million to the
Tribe.
 
3. Leases:
 
   At December 31, 1998, the Authority was obligated under non-cancelable
operating leases and capital leases to make future minimum lease payments as

maintenance of various financial covenants and terms including a fixed charge
coverage ratio, a debt to adjusted net worth ratio, and a debt service coverage
ratio.

4. Commitments and Contingencies:
 
 The Mohegan Compact
 
   The Mohegan Compact stipulates that a portion of the revenues earned on slot
machines must be paid to the State of Connecticut ("Slot Win Contribution").
For each 12-month period commencing July 1, 1995, the Slot Win Contribution
shall be the lesser of (a) 30% of gross revenues from slot machines, or (b) the
greater of (i) 25% of gross revenues from slot machines or (ii) $80 million.
 
   The Slot Win Contribution payments will not be required if the State of
Connecticut legalizes any other (except those consented to by the Mashantucket
Pequot Tribe and the Mohegan Tribe) gaming operations with slot machines or
other commercial casino games within Connecticut. The Authority has reflected
$28.4 million and $22.0 million of gaming expense in its financial statements
for the required Slot Win Contribution for the quarters ended December 31, 1998
and 1997, respectively.
 
 Litigation
 
   The Authority is a defendant in certain litigation incurred in the normal
course of business. In the opinion of management, based on the advice of
counsel, the aggregate liability, if any, arising from such litigation will not
have a material adverse effect on the Authority's financial position or results
of operations.
 
 Town of Montville Agreement
 
   On June 16, 1994, the Tribe and the Town of Montville (the "Town") entered
into an agreement whereby the Tribe agreed to pay to the Town an annual payment
of $500,000 to minimize the impact to the Town resulting from decreased tax
revenues on reservation land held in trust. Two annual $500,000 payments
payable beginning one year after the commencement of slot machine gaming
activities, were remitted to the Town of Montville in October 1998 and 1997,
respectively. Additionally, the Tribe agreed to make a payment of $3.0 million
towards infrastructure improvements to the Town's water system. The Tribe has
assigned its rights and obligations in this agreement to the Authority. The
Town is billing the Authority for the infrastructure improvements as the Town's
costs are incurred. As of December 31, 1998, the Authority has paid $1.6
million to the Town of Montville towards improvements to the municipal water
system, which has been included in other assets in the accompanying balance
sheet and will be amortized over 40 years.
 
5. Related Party Transactions:
 
   The Tribe provides governmental and administrative services to the Authority
in conjunction with the operation of Mohegan Sun. For the quarters ended
December 31, 1998 and 1997, the Authority incurred expenses of $1.7 million and
$1.3 million, respectively, for such services.
 
6. TCA Agreements:
 
 Management Agreement
 
   The Tribe and TCA entered into the Amended and Restated Gaming Facility
Management Agreement (the "Management Agreement"), pursuant to which the Tribe
has retained and engaged TCA, on an independent contractor basis, to operate,
manage and market Mohegan Sun.

                               December 31, 1998
                                  (Unaudited)
   The Tribe has assigned its rights and obligations under the Management
Agreement to the Authority. The term of the Management Agreement is seven
years. TCA holds responsibility to manage Mohegan Sun in exchange for payments
ranging from 30% to 40% of net income, before management fees, as defined,
depending upon profitability levels. Management fees totaled $13.6 million and
$7.4 million, respectively, for the quarters ended December 31, 1998 and 1997.
At December 31, 1998, $3.7 million was owed to TCA in connection with the
Management Agreement.
 
 Relinquishment Agreement
 
   In February 1998, the Authority and TCA entered into an agreement, (the
"Relinquishment Agreement"). The Relinquishment Agreement supercedes the
Management Agreement effective the later of January 1, 2000, or the date the
Existing Secured Notes are refinanced or repaid (the "Relinquishment Date"),
and provides that the Authority shall make certain payments to TCA out of, and
determined as a percentage of, the gross revenues generated by the Mohegan Sun
over a 15-year period commencing on the Relinquishment Date. The payments
("Senior Relinquishment Payments" and "Junior Relinquishment Payments"), are
calculated as 2.5% of Revenues each, as defined, but each has its own payment
schedule and priority. Senior Relinquishment Payments commence at the end of
the first three-month period following the Relinquishment Date and continue at
the end of each three-month period occurring thereafter until the fifteenth
anniversary of the Relinquishment Date. Junior Relinquishment Payments commence
at the end of the first six-month period following the Relinquishment Date and
continue at the end of each six-month period occurring thereafter until the
fifteenth anniversary of the Relinquishment Date. Each Senior Relinquishment
Payment and Junior Relinquishment Payment is an amount equal to 2.5% of the
Revenues generated by Mohegan Sun over the immediately preceding three-month or
six-month payment period, as the case may be. "Revenues" are defined as gross
gaming revenues (other than Class II gaming revenue) and all other facility
revenues (including, without limitation, hotel revenues, fees or receipts from
convention/events center in the expansion and all rental or other receipts from
lessees and concessionaires operating in the facility but not the gross
receipts of such lessees, licenses and concessionaires). The Authority, in
accordance with Financial Accounting Standards Board Statement No. 5, ("SFAS
No. 5"), "Accounting for Contingencies", has recorded a relinquishment
liability of the estimated present value of its obligation under the
Relinquishment Agreement. The liability is estimated at $549.1 million as of
December 31, 1998 and will be reassessed periodically. This amount was derived
by discounting the present value of 5% of projected gross revenues by the
Authority's risk free investment rate. The Authority has also recognized the
value of the trademarks associated with the Mohegan Sun brand name. The Mohegan
Sun trademarks, which were appraised by an independent consultant, were valued
at $130.0 million at December 31, 1998. TCA's services will be retained,
however, in the development and construction of the expansion (See "Development
Agreement").
 
 Development Agreement
 
   The Authority has also negotiated a second agreement with TCA (the
"Development Agreement"), which will make TCA the exclusive developer of the
planned expansion of Mohegan Sun. Under the Development Agreement, TCA will
oversee the planning, design and construction of the expansion of Mohegan Sun
and will receive compensation of $14 million for such services.
 
7. Employee Benefits Plans
 
   Effective January 1, 1999 pursuant to Section 401 of the Internal Revenue
Code, the Authority increased the employer matching contribution to match of
its retirement savings plan. The plan allows employees of the

                   NOTES TO FINANCIAL STATEMENTS--(Continued)
 
                               December 31, 1998
                                  (Unaudited)
Authority to defer up to the lesser of the maximum amount prescribed by the
Internal Revenue Code or 15% of their income on a pre-tax basis, through
contributions to this plan. The Authority now matches 100% of eligible
employees' contributions up to a maximum of 3% of their individual earnings.
 
8. Subsequent Events:
 
   On January 15, 1999, the Authority initiated a Tender Offer and Consent
Solicitation for the repurchase of all of the Existing Secured Notes. The offer
will expire at 12:00 midnight, New York City time on February 12, 1999, unless
extended or terminated earlier. The tender offer price for the Existing Secured
Notes is expected to be approximately $214 million. Funding of the Tender Offer
and Consent Solicitation will require additional sources of funding, which may
include public and private debt and bank financing. There can be no assurance
that the Authority will be able to obtain such financing, although the
Authority believes that the current operating results of Mohegan Sun make such
financing a viable likelihood. As of January 29, 1999, holders of 99.9% of the
Existing Secured Notes have accepted the Tender Offer and Consent Solicitation.

Item 20. Indemnification of Directors and Officers
 
   All current and former officers, employees and members of the Authority are
entitled to be indemnified by the Authority pursuant to Section 7 of Mohegan
Tribal Ordinance No. 95-7/15-1, the ordinance that established the Authority,
"against reasonable expenses actually and necessarily incurred by that person
in connection with the defense of any action, suit or proceeding in which that
person is made a party by reason of being, or having been, such officer,
employee or member of the Authority." Indemnification is not available in the
event of an adjudication of liability for negligence or misconduct in the
performance of duty or for actions beyond the scope of employment. The
Authority also may reimburse such persons for the reasonable costs of
settlements of actions, suits or proceedings (so long as such settlements do
not involve findings of neglect, misconduct or ultra vires acts) deemed by the
Management Board to be in the best interests of the Authority.

     Schedule II--Valuation and Qualifying Accounts

Item 22. Undertakings
 
   Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities
Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless in
the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.
 
   The undersigned registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Items 4, 10(b), 11 or 13 of this Form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of this Registration Statement through
the date of responding to the request.
 
   The undersigned registrant hereby undertakes to supply by means of a post-
effective amendment all information concerning a transaction, and the company
being acquired involved therein, that was not the subject of and included in
this Registration Statement when it became effective.
 
   The undersigned registrant hereby undertakes to file, during any period in
which offers or sales are being made, a post-effective amendment to this
Registration Statement;
 
     (i) to include any prospectus required by Section 10(a)(3) of the
  Securities Act of 1933 (the "Securities Act");
 
     (ii) to reflect in the prospectus any facts or events arising after the
  effective date of this Registration Statement (or the most recent post-
  effective amendment hereof) which, individually or in the aggregate,
  represents a fundamental change in the information set forth in this
  Registration Statement. Notwithstanding the foregoing, any increase or
  decrease in volume of securities offered (if the total dollar value of
  securities offered would not exceed that which was registered) and any
  deviation from the low or high end of the estimated maximum offering range
  may be reflected in the form of prospectus filed with the Securities and
  Exchange Commission pursuant to Rule 424(b) if, in the aggregate, the
  changes in volume and price represent no more than a 20% change in the
  maximum aggregate offering price set forth in the "Calculation of
  Registration Fee" table in this Registration Statement when it becomes
  effective; and
 
     (iii) to include any material information with respect to the plan of
  distribution not previously disclosed in this Registration Statement or any
  material change to such information in this Registration Statement.
 
   The undersigned registrant hereby undertakes that, for the purpose of
determining any liability under the Securities Act, each such post-effective
amendment shall be deemed to be a new registration statement relating to the
securities offered therein, and the offering of such securities at that time
shall be deemed to be the initial bona fide offering thereof.
 
   The undersigned registrant hereby undertakes to remove from registration by
means of a post-effective amendment any of the securities being registered
which remain unsold at the termination of the offering.
 
   The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act that is incorporated by reference in the registration statement
shall be deemed to be a new registration statement relating to the securities
offered therein, and the offering of such securities at that time shall be
deemed to be the initial bona fide offering thereof.

Salomon Smith Barney Inc.
As Representatives of the Initial Purchasers
388 Greenwich Street
New York, New York  10013

Ladies and Gentlemen:

Mohegan Tribal Gaming Authority (the "Authority"), an instrumentality of the
Mohegan Tribe of Indians of Connecticut (the "Tribe"), proposes to issue and
sell to the several parties named in Schedule I hereto (the "Initial
Purchasers"), for whom you (the "Representatives") are acting as
representatives, $200,000,000 principal amount of its 8 1/8% Senior Notes due
2006 (the "Senior Securities") and $300,000,000 principal amount of its 8 3/4%
Senior Subordinated Notes due 2009 (the "Senior Subordinated Securities" and,
collectively with the Senior Securities, the "Securities"). The Senior
Securities are to be issued under an indenture (the "Senior Indenture") to be
dated as of March 3, 1999 among the Authority, the Tribe and First Union
National Bank as trustee (the "Senior Trustee"). The Senior Subordinated
Securities are to be issued under an indenture (the "Senior Subordinated
Indenture") to be dated as of March 3, 1999 among the Authority, the Tribe and
State Street Bank and Trust Company as trustee (the "Senior Subordinated
Trustee"). The Senior Indenture and the Senior Subordinated Indenture are
collectively referred to herein as the "Indentures", and the Senior Trustee and
the Senior Subordinated Trustee are collectively referred to herein as the
"Trustees". The Securities each have the benefit of a Registration Rights
Agreement (the "Senior Registration Rights Agreement" and the "Senior
Subordinated Registration Rights Agreement," collectively, the "Registration
Rights Agreements"), both to be dated as of March 3, 1999, between the Authority
and the Initial Purchasers, pursuant to which the Authority has agreed to
register under the Act another series of debt securities of the Authority each
with terms substantially identical to the Securities (collectively, the
"Exchange Securities") to be offered in exchange for the Securities (the
"Exchange Offer"), subject to the terms and conditions therein specified. To the
extent there
<PAGE>
 
are no additional parties listed on Schedule I other than you, the term
Representatives as used herein shall mean you as the Initial Purchasers, and the
terms Representatives and Initial Purchasers shall mean either the singular or
plural as the context requires. The use of the neuter in this Purchase Agreement
shall include the feminine and masculine wherever appropriate. Certain terms
used herein are defined in Section 19 hereof.

     The offering of the Securities is being made in connection with the Tender
Offer and Consent Solicitation for the Authority's 13 1/2% Senior Secured Notes
with Cash Flow Participation Interest and the arrangement of a senior secured
bank credit facility (the "Bank Credit Facility") (the "Concurrent
Transactions").

     The sale of the Securities to the Initial Purchasers will be made without
registration of the Securities under the Act in reliance upon exemptions from
the registration requirements of the Act.

     In connection with the sale of the Securities, the Authority has prepared a
preliminary offering memorandum, dated February 3, 1999 (as amended or
supplemented at the Execution Time, including any and all exhibits thereto, the
"Preliminary Memorandum"), and a final offering memorandum, dated February 24,
1999 (as amended or supplemented at the Execution Time, including any and all
exhibits thereto the "Final Memorandum"). Each of the Preliminary Memorandum and
the Final Memorandum sets forth certain information concerning the Authority and
the Securities. The Authority hereby confirms that it has authorized the use of
the Preliminary Memorandum and the Final Memorandum, and any amendment or
supplement thereto, in connection with the offer and sale of the Securities by
the Initial Purchasers.

     1. Representations and Warranties. The Authority represents and warrants to
each Initial Purchaser, as set forth below in this Section 1, and the Tribe
represents and warrants to each Initial Purchaser with respect to paragraphs
1(l),(o),(p) and (s) as set forth below.

          (a) The Preliminary Memorandum, at the date thereof, did not contain
     any untrue statement of a material fact or omit to state any material fact
     necessary to make the statements therein, in the light of the circumstances
     under which they were made, not misleading. At the Execution Time, on the
     Closing Date or on any settlement date, as the case may be, the Final
     Memorandum did not, and will not (and any amendment or supplement thereto,
     at the date thereof, at the Closing Date and on any settlement date, will
     not), contain any untrue statement of a material fact or omit to state any
     material fact necessary to make the statements therein, in the light of the
     circumstances under which they were made, not misleading; provided,
     however, that the Authority makes no representation or warranty as to the
     information contained in or omitted from the Preliminary Memorandum or the
     Final Memorandum, or any amendment or supplement thereto, in reliance upon
     and in conformity with information furnished in writing to the Authority by
     or on behalf of the Initial Purchasers through the Representatives
     specifically for inclusion therein.

          (b) Neither the Authority nor any of its Affiliates, nor any person
     acting on its behalf (provided that no representation is made as to the
     Initial Purchasers or any person acting on their behalf) has, directly or
     indirectly, made offers or sales of any


                                       2
<PAGE>
 
     security, or solicited offers to buy any security, under circumstances that
     would require the registration of the Securities under the Act.

          (c) Neither the Authority nor any of its Affiliates, nor any person
     acting on its behalf (provided that no representation is made as to the
     Initial Purchasers or any person acting on their behalf) has engaged in any
     form of general solicitation or general advertising (within the meaning of
     Regulation D) in connection with any offer or sale of the Securities in the
     United States.

          (d) The Securities satisfy the eligibility requirements of Rule
     144A(d)(3) under the Act.

          (e) Neither the Authority nor any of its Affiliates, nor any person
     acting on its behalf (provided that no representation is made as to the
     Initial Purchasers or any person acting on their behalf) has engaged in any
     directed selling efforts with respect to the Securities, and each of them
     has complied with the offering restrictions requirement of Regulation S
     under the Act. Terms used in this paragraph have the meanings given to them
     by Regulation S.

          (f) The Authority expects to be advised by the NASD's PORTAL Market
     that as of the Closing Date the Securities will have been designated
     PORTAL-eligible securities in accordance with the rules and regulations of
     the NASD.

          (g) The Authority is not, and after giving effect to the offering and
     sale of the Securities and the application of the net proceeds thereof as
     described in the Final Memorandum will not be, an "investment company"
     within the meaning of the Investment Company Act, without taking account of
     any exemption arising out of the number of holders of the Authority's
     securities.

          (h) The Authority is in compliance with the reporting requirements of
     Section 13 or 15(d) of the Exchange Act.

          (i) The Authority has not paid or agreed to pay to any person any
     compensation for soliciting another to purchase the Securities (except as
     contemplated by this Purchase Agreement).

          (j) The Authority has not taken, directly or indirectly, any action
     designed to cause or which has constituted or which might reasonably be
     expected to cause or result, under the Exchange Act or otherwise, in the
     stabilization or manipulation of the price of any security of the Authority
     to facilitate the sale or resale of the Securities.

          (k) The information provided by the Authority pursuant to Section 5(h)
     hereof will not, at the date thereof, contain any untrue statement of a
     material fact or omit to state any material fact necessary to make the
     statements therein, in the light of the circumstances under which they were
     made, not misleading.

          (l) The Tribe is a federally recognized Indian Tribe, with authority
     to enter into and perform its obligations under the Agreements. The
     Constitution of the Tribe, amended and restated in its entirety and
     approved on April 12, 1996 (the "Constitution"), was validly adopted by the
     Tribe, is effective according to its terms, and is the law of the Tribe.

          (m) The Authority (A) has been duly established, is validly existing
     under the Constitution, as amended, (B) has all requisite power and
     authority to carry on its business as it is currently being conducted and
     as described in the Final Memorandum and to own, lease and operate its
     properties, and (C) is duly qualified and authorized to do business in each
     jurisdiction in which the nature of its business or its ownership or
     leasing of property requires such qualification except, with respect to
     this clause (C), where the failure to be so qualified or in good standing
     does not and could not reasonably be expected to (x) individually or in
     aggregate, result in a material adverse effect on the properties, business,
     results of operations, condition (financial or otherwise), affairs or
     prospects of the Authority, (y) interfere with or adversely affect the
     issuance or marketability of the Securities pursuant hereto or (z) in any
     manner draw into question the validity of this Purchase Agreement or any
     agreements or the transactions described in the Final Memorandum under the
     caption "Use of Proceeds". The Authority will have no direct or indirect
     subsidiaries as of the Closing Date.

          (n) The statements in the Final Memorandum under the headings "Certain
     Federal Income Tax Consequences," "Description of Notes," "Business--The
     Expansion," "Business--Environmental Matters," "Description of Other
     Indebtedness," "Mohegan Tribe of Indians of Connecticut," "Government
     Regulation" and "Other Material Agreements" fairly summarize the matters
     therein described.

          (o) This Purchase Agreement has been duly authorized, executed and
     delivered by the Authority and the Tribe; the Senior Indenture and the
     Senior Subordinated Indenture have each been duly authorized and, assuming
     due authorization, execution and delivery thereof by the Trustee, when
     executed and delivered by the Authority and the Tribe, will constitute
     legal, valid, binding instruments enforceable against the Authority and the
     Tribe in accordance with their terms (subject, as to the enforcement of
     remedies, to applicable bankruptcy, reorganization, insolvency, moratorium
     or other laws affecting creditors' rights generally from time to time in
     effect and to general principles of equity and public policy provided,
     however that the Authority makes no representation as to the choice of
     laws); the Securities have been duly authorized, and, when executed and
     authenticated in accordance with the provisions of the Senior Indenture or
     the Senior Subordinated Indenture, as the case may be, and delivered to and
     paid for by the Initial Purchasers, will have been duly executed and
     delivered by the Authority and will constitute the legal, valid and binding
     obligations of the Authority entitled to the benefits of the Senior
     Indenture or the Senior Subordinated Indenture, as the case may be
     (subject, as to the enforcement of remedies, to applicable bankruptcy,
     reorganization, insolvency, moratorium or other laws affecting creditors'
     rights generally from time to time in effect and to general principles of
     equity and public policy provided, however, that the Authority makes no
     representation as to the choice of laws); and the Senior Registration
     Rights Agreement and the Senior Subordinated


                                       4
<PAGE>
 
     Registration Rights Agreement have been duly authorized and, when executed
     and delivered by the Authority, will constitute legal, valid, binding and
     enforceable instruments of the Authority (subject, as to the enforcement of
     remedies, to applicable bankruptcy, reorganization, insolvency, moratorium
     or other laws affecting creditors' rights generally from time to time in
     effect and to general principles of equity and public policy provided,
     however, that the Authority makes no representation as to the choice of
     laws).

          (p) No consent, approval, authorization, filing with or order of any
     court or governmental agency or body is required to be obtained or made by
     the Authority or the Tribe in connection with the transactions contemplated
     herein or in the Indentures, or the Registration Rights Agreements or the
     Concurrent Transactions, except (A) such as will be obtained under the Act
     and such as may be required under the blue sky laws of any jurisdiction in
     connection with the purchase and distribution of the Securities by the
     Initial Purchasers in the manner contemplated herein and in the Final
     Memorandum and the Registration Rights Agreements and (B) such as will be
     obtained from the National Indian Gaming Commission ("NIGC") or its
     Chairman, the Secretary of the Interior ("Secretary"), or the Bureau of
     Indian Affairs ("BIA") prior to the Closing Date.

          (q) None of the execution and delivery of the Indentures, this
     Purchase Agreement or the Registration Rights Agreements, the issue and
     sale of the Securities, the consummation of the Concurrent Transactions, or
     the consummation of any other of the transactions herein or therein
     contemplated, or the fulfillment of the terms hereof or thereof will
     conflict with or result in (A) violation any of the organizational,
     statutory or legal documents of the Authority or the Tribe, (B) default in
     the performance of any bond, debenture, note, indenture, mortgage, deed of
     trust note agreement, loan agreement or other agreement, obligation,
     condition, covenant or instrument to which the Authority or the Tribe is
     bound or any of their respective properties is subject, or (C) violation of
     any local, tribal, state or federal law, statue, ordinance, rule,
     regulation, requirement, judgment or court decree (including, without
     limitation, any requirement, regulation or decree under the Indian Gaming
     Regulatory Act of 1988 (collectively, "Gaming Regulations") applicable to
     the Authority or any of its assets or properties (whether owned or
     leased)), other than, in the case of clauses (B) and (C), any default or
     violation that could not reasonably be expected to have a material adverse
     effect on the Authority. To the best knowledge of the Authority, there
     exists no condition that, with notice, the passage of time or otherwise,
     would constitute a default under any such document or instrument.

          (r) The historical financial statements and schedules of the Authority
     included in the Final Memorandum present fairly in all material respects
     the financial condition, results of operations and cash flows of the
     Authority as of the dates and for the periods indicated, comply as to form
     with the applicable accounting requirements of the Act and have been
     prepared in conformity with generally accepted accounting principles
     applied on a consistent basis throughout the periods involved (except as
     otherwise noted therein); the selected financial data set forth under the
     caption "Selected Financial Data" in the Final Memorandum fairly present,
     on the basis stated in the Final Memorandum,


                                       5
<PAGE>
 
     the information included therein; the "As adjusted" financial information
     included in the Final Memorandum includes assumptions that provide a
     reasonable basis for presenting the significant effects directly
     attributable to the transactions and events described therein, the related
     "As adjusted" adjustments give appropriate effect to those assumptions, and
     the "As adjusted" adjustments reflect the proper application of those
     adjustments to the historical financial statement amounts in the "As
     adjusted" financial information included in the Final Memorandum; the "As
     adjusted" financial information included in the Final Memorandum complies
     as to form in all material respects with the applicable accounting
     requirements of Regulation S-X under the Act; and the "As adjusted"
     adjustments have been properly applied to the historical amounts in the
     compilation of that information.

          (s) There is no action, suit or proceeding by or before any court or
     governmental agency, authority or body or any arbitrator involving the
     Authority, the Tribe or their respective property is pending or, to the
     best knowledge of the Authority or the Tribe, threatened that (i) could
     reasonably be expected to have a material adverse effect on the performance
     of this Purchase Agreement, the Indentures, the Registration Rights
     Agreements or the consummation of any of the transactions contemplated
     hereby or thereby; or (ii) could reasonably be expected to have a material
     adverse effect on the condition (financial or otherwise), prospects,
     earnings, business or properties of the Authority, except as set forth in
     or contemplated in the Final Memorandum (exclusive of any amendment or
     supplement thereto entered into after the date hereof).

          (t) The Authority owns or leases all such properties as are necessary
     to the conduct of its operations as presently conducted.

          (u) The Authority is not (A) in violation any of the organizational,
     statutory or legal documents of the Authority or the Tribe, (B) in default
     in the performance of any bond, debenture, note, indenture, mortgage, deed
     of trust note agreement, loan agreement or other agreement, obligation,
     condition, covenant or instrument to which the Authority or the Tribe is
     bound or any of their respective properties is subject, or (C) in violation
     of any local, tribal, state or federal law, statue, ordinance, rule,
     regulation, requirement, judgment or court decree (including, without
     limitation, any Gaming Regulations applicable to the Authority or any of
     its assets or properties (whether owned or leased)), other than, in the
     case of clauses (B) and (C), any default or violation that could not
     reasonably be expected to have a material adverse effect on the Authority.
     To the best knowledge of the Authority, there exists no condition that,
     with notice, the passage of time or otherwise, would constitute a default
     under any such document or instrument other than a default that could not
     reasonably be expected to have a material adverse effect.

          (v) Arthur Andersen LLP, who have certified certain financial
     statements of the Authority included in the Final Memorandum and delivered
     their report with respect to the audited financial statements included in
     the Final Memorandum, are independent public accountants with respect to
     the Authority within the meaning of the Act and the applicable published
     rules and regulations thereunder.


                                       6

          (w) There are no stamp or other issuance or transfer taxes or duties
     or other similar fees or charges required to be paid in connection with the
     execution and delivery of this Purchase Agreement or the issuance or sale
     by the Authority of the Securities.

          (x) No action or proceeding with respect to any labor dispute with
     employees of the Authority exists, or to the Authority's knowledge is
     threatened or imminent.

          (y) The Authority is insured by insurers of recognized financial
     responsibility against such losses and risks and in such amounts as are
     prudent and customary in the businesses in which it is engaged; all
     policies of insurance and fidelity or surety bonds insuring the Authority
     or its business, assets, employees, officers and Management Board Members
     are in full force and effect; the Authority is in compliance with the terms
     of such policies and instruments in all material respects; and there are no
     claims by the Authority under any such policy or instrument as to which any
     insurance company is denying liability or defending under a reservation of
     rights clause; the Authority has not been refused any insurance coverage
     sought or applied for; and the Authority has no reason to believe that it
     will not be able to renew its existing insurance coverage as and when the
     coverage expires or to obtain similar coverage from similar insurers as may
     be necessary to continue its business at a cost that would not have a
     material adverse effect on the condition (financial or otherwise),
     prospects, earnings, business or properties of the Authority whether or not
     arising from transactions in the ordinary course of business, except as set
     forth in or contemplated in the Final Memorandum (exclusive of any
     amendment or supplement thereto).

          (z) The Authority possesses all licenses, certificates, permits and
     other authorizations issued by the appropriate federal, state or foreign
     regulatory authorities necessary to conduct its business, and the Authority
     has not received any notice of proceedings relating to the revocation or
     modification of any such certificate, authorization or permit which, singly
     or in the aggregate, if the subject of an unfavorable decision, ruling or
     finding, would have a material adverse effect on the condition (financial
     or otherwise), prospects, earnings, business or properties of the
     Authority, whether or not arising from transactions in the ordinary course
     of business, except as set forth in or contemplated in the Final Memorandum
     (exclusive of any amendment or supplement thereto).

          (aa) The Authority maintains a system of internal accounting controls
     sufficient to provide reasonable assurance that (i) transactions are
     executed in accordance with management's general or specific
     authorizations; (ii) transactions are recorded as necessary to permit
     preparation of financial statements in conformity with generally accepted
     accounting principles and to maintain asset accountability; (iii) access to
     assets is permitted only in accordance with management's general or
     specific authorization; and (iv) the recorded accountability for assets is
     compared with the existing assets at reasonable intervals and appropriate
     action is taken with respect to any differences.


                                       7

          (bb) The Authority (i) is in compliance with any and all applicable
     tribal, federal, state and local laws and regulations relating to the
     protection of human health and safety, the environment or hazardous or
     toxic substances or wastes, pollutants or contaminants ("Environmental
     Laws"); (ii) has received and is in compliance with all permits, licenses
     or other approvals required of it under applicable Environmental Laws to
     conduct its businesses; and (iii) has not received notice of any actual or
     potential liability for the investigation or remediation of any disposal or
     release of hazardous or toxic substances or wastes, pollutants or
     contaminants; except where such non-compliance with Environmental Laws,
     failure to receive required permits, licenses or other approvals, or
     liability would not, individually or in the aggregate, have a material
     adverse effect on the Authority, except as set forth in or contemplated in
     the Final Memorandum (exclusive of any amendment or supplement thereto).
     Except as set forth in the Final Memorandum, the Authority has not been
     named as a "potentially responsible party" under the Comprehensive
     Environmental Response, Compensation, and Liability Act of 1980, as
     amended.

          (cc) In the ordinary course of its business, the Authority
     periodically reviews the effect of Environmental Laws on the business,
     operations and properties of the Authority, in the course of which it
     identifies and evaluates associated costs and liabilities (including,
     without limitation, any capital or operating expenditures required for
     clean-up, closure of properties or compliance with Environmental Laws, or
     any permit, license or approval, any related constraints on operating
     activities and any potential liabilities to third parties). On the basis of
     such review, the Authority has reasonably concluded that such associated
     costs and liabilities would not, singly or in the aggregate, have a
     material adverse effect on the condition (financial or otherwise),
     prospects, earnings, business or properties of the Authority except as set
     forth in or contemplated in the Final Memorandum (exclusive of any
     amendment or supplement thereto).

          (dd) The Authority owns, possesses, licenses or has other rights to
     use on reasonable terms, all patents, patent applications, trade and
     service marks, trade and service mark registrations, trade names,
     copyrights, licenses, inventions, trade secrets, technology, know-how and
     other intellectual property necessary for the conduct of its business as
     now conducted or as proposed in the Final Memorandum to be conducted
     (collectively, the "Intellectual Property"). Except as set forth in or
     contemplated by the Final Memorandum (a) there are no rights of third
     parties to any such Intellectual Property; (b) to the Authority's knowledge
     there is no material infringement by third parties of any such Intellectual
     Property; (c) there is no pending or, to the Authority`s knowledge,
     threatened action, suit, proceeding or claim by others challenging the
     Authority's rights in or to any such Intellectual Property, and the
     Authority is unaware of any facts which would form a reasonable basis for
     any such claim; (d) there is no pending or, to the Authority's knowledge,
     threatened action, suit, proceeding or claim by others challenging the
     validity or scope of any such Intellectual Property, and the Authority is
     unaware of any facts which would form a reasonable basis for any such
     claim; (e) there is no pending or, the Authority's knowledge threatened
     action, suit, proceeding or claim by others that the Authority infringes or
     otherwise violates any patent, trademark, copyright, trade secret or other
     proprietary rights of others, and the Authority is unaware of any


                                       8
<PAGE>
 
     other fact which would form a reasonable basis for any such claim; (f) to
     the Authority's knowledge, there is no U.S. patent or published U.S. patent
     application which contains claims that dominate or may dominate any
     Intellectual Property described in the Final Memorandum as being owned by
     or licensed to the Authority or that interferes with the issued or pending
     claims of any such Intellectual Property; and (g) there is no prior act of
     which the Authority is aware that may render any U.S. patent held by the
     Authority invalid or any U.S. patent application held by the Authority
     unpatentable which has not been disclosed to the U.S. Patent and Trademark
     Office.

          (ee) The Authority has implemented a comprehensive, detailed program
     to analyze and address the risk that the computer hardware and software
     used by them may be unable to recognize and properly execute date-sensitive
     functions involving certain dates prior to and any dates after December 31,
     1999 (the "Year 2000 Problem"), and has determined that such risk will be
     remedied on a timely basis and will not have a material adverse effect upon
     the financial condition and results of operations of the Authority; and the
     Authority believes, after due inquiry, that each supplier, vendor, customer
     or financial service organization used or serviced by the Authority has
     remedied or will remedy on a timely basis the Year 2000 Problem, except to
     the extent that a failure to remedy by any such supplier, vendor, customer
     or financial service organization would not have a material adverse effect
     on the Authority. The Authority is in compliance with the Commission's
     staff legal bulletin No. 5 dated January 12, 1998 related to Year 2000
     compliance.

          (ff) The statistical and market-related data included in the Final
     Memorandum are based on or derived from sources which the Authority
     believes to be reliable and accurate in all material respects.

     Any certificate signed by any officer of the Authority and delivered to the
Representatives or counsel for the Initial Purchasers in connection with the
offering of the Securities shall be deemed a representation and warranty by the
Authority (and not individually by such officer), as to matters covered thereby,
to each Initial Purchaser.

     2. Purchase and Sale. Subject to the terms and conditions and in reliance
upon the representations and warranties herein set forth, the Authority agrees
to sell to each Initial Purchaser, and each Initial Purchaser agrees, severally
and not jointly, to purchase from the Authority, at a purchase price of 8 1/8%
of the principal amount thereof with respect to the Senior Securities and at a
purchase price of 8 3/4% of the principal amount thereof with respect to the
Senior Subordinated Securities, in each case plus accrued interest, if any, from
February 24, 1999 to the Closing Date, the principal amount of such Securities
set forth opposite such Initial Purchaser's name in Schedule I hereto.

     3. Delivery and Payment. Delivery of and payment for the Securities shall
be made at 9:00 A.M., New York City time, on March 3, 1999, or at such time on
such later date (not later than March 10 1999) as the Representatives shall
designate, which date and time may be postponed by agreement between the
Representatives and the Authority or as provided in Section 9 hereof (such date
and time of delivery and payment for the Securities being herein called the
"Closing Date"). Delivery of the Securities shall be made to the Representatives
for


                                       9
<PAGE>
 
the respective accounts of the several Initial Purchasers against payment by the
several Initial Purchasers through the Representatives of the purchase price
thereof to or upon the order of the Authority by wire transfer payable in
same-day funds to the account specified by the Authority. Delivery of the
Securities shall be made through the facilities of The Depository Trust Company
unless the Representatives shall otherwise instruct.

     4. Offering by Initial Purchasers. Each Initial Purchaser, severally and
not jointly, represents and warrants to and agrees with the Authority that:

          (a) It has not offered or sold, and will not offer or sell, any
     Securities except (i) to those it reasonably believes after due inquiry to
     be qualified institutional buyers (as defined in Rule 144A under the Act)
     and that, in connection with each such sale, it has taken or will take
     reasonable steps to ensure that the purchaser of such Securities is aware
     that such sale is being made in reliance on Rule 144A or (ii) in accordance
     with the restrictions set forth in Exhibit A hereto.

          (b) Neither it nor any of its Affiliates nor any person acting on its
     or their behalf has engaged in any form of general solicitation or general
     advertising (within the meaning of Regulation D) in connection with any
     offer or sale of the Securities in the United States.

          (c) Neither it nor any of its Affiliates nor any person acting on its
     or their behalf has, directly or indirectly, made offers or sales of any
     security, or solicited offers to buy any security, under circumstances that
     would require the registration of the Securities under the Act.

     5. Agreements. The Authority agrees with each Initial Purchaser that:

          (a) The Authority will furnish to each Initial Purchaser and to
     counsel for the Initial Purchasers, without charge, during the period
     referred to in paragraph (c) below, as many copies of the Final Memorandum
     and any amendments and supplements thereto as it may reasonably request.

          (b) The Authority will not amend or supplement the Final Memorandum
     without the prior written consent of the Representatives.

          (c) If at any time prior to the completion of the sale of the
     Securities by the Initial Purchasers (as determined by the
     Representatives), any event occurs as a result of which the Final
     Memorandum, as then amended or supplemented, would include any untrue
     statement of a material fact or omit to state any material fact necessary
     to make the statements therein, in the light of the circumstances under
     which they were made, not misleading, or if it should be necessary to amend
     or supplement the Final Memorandum to comply with applicable law, the
     Authority promptly (i) will notify the Representatives of any such event;
     (ii) subject to the requirements of paragraph (b) of this Section 5, will
     prepare an amendment or supplement that will correct such statement or
     omission or effect such compliance; and (iii) will supply any supplemented
     or amended Final Memorandum to the several Initial Purchasers and counsel
     for the Initial Purchasers without charge in such quantities as you may
     reasonably request.


                                       10
<PAGE>
 
          (d) The Authority will arrange, if necessary, for the qualification of
     the Securities for sale by the Initial Purchasers under the laws of such
     jurisdictions as the Initial Purchasers may designate and will maintain
     such qualifications in effect so long as required for the sale of the
     Securities; provided that in no event shall the Authority be obligated to
     qualify to do business in any jurisdiction where it is not now so qualified
     or to take any action that would subject it to service of process in suits,
     other than those arising out of the offering or sale of the Securities, in
     any jurisdiction where it is not now so subject. The Authority will
     promptly advise the Representatives of the receipt by the Authority of any
     notification with respect to the suspension of the qualification of the
     Securities for sale in any jurisdiction or the initiation or threatening of
     any proceeding for such purpose.

          (e) The Authority will not, and will not permit any of its Affiliates
     to, resell any Securities that have been acquired by any of them.

          (f) Neither the Authority nor any of its Affiliates, nor any person
     acting on its behalf will, directly or indirectly, make offers or sales of
     any Security, or solicit offers to buy any Security, under circumstances
     that would require the registration of the Securities under the Act.

          (g) Neither the Authority, nor any of its Affiliates, nor any person
     acting on its behalf will engage in any form of general solicitation or
     general advertising (within the meaning of Regulation D) in connection with
     any offer or sale of the Securities in the United States.

          (h) So long as any of the Securities are "restricted securities"
     within the meaning of Rule 144(a)(3) under the Act, the Authority will,
     during any period in which they are not subject to and in compliance with
     Section 13 or 15(d) of the Exchange Act or they are not exempt from such
     reporting requirements pursuant to and in compliance with Rule 12g3-2(b)
     under the Exchange Act, provide to each holder of such restricted
     securities and to each prospective purchaser (as designated by such holder)
     of such restricted securities, upon the request of such holder or
     prospective purchaser, any information required to be provided by Rule
     144A(d)(4) under the Act. This covenant is intended to be for the benefit
     of the holders, and the prospective purchasers designated by such holders,
     from time to time of such restricted securities.

          (i) So long as any of the Securities are outstanding, the Authority
     will furnish to the Initial Purchasers (i) as soon as available, a copy of
     each report of the Authority mailed to securityholders generally or filed
     with any stock exchange or regulatory body and (ii) from time to time such
     other information concerning the Authority as the Initial Purchasers may
     reasonably request.

          (j) Neither the Authority nor any of its Affiliates, nor any person
     acting on its behalf will engage in any directed selling efforts with
     respect to the Securities, and each of them will comply with the offering
     restrictions requirement of Regulation S. Terms used in this paragraph have
     the meanings given to them by Regulation S.


                                       11

          (k) The Authority will cooperate with the Representatives and use its
     best efforts to permit the Securities to be eligible for clearance and
     settlement through The Depository Trust Company.

          (l) The Authority will not for a period of 180 days following the
     Execution Time, without the prior written consent of Salomon Smith Barney
     Inc., offer, sell or contract to sell, or otherwise dispose of (or enter
     into any transaction which is designed to, or might reasonably be expected
     to, result in the disposition (whether by actual disposition or effective
     economic disposition due to cash settlement or otherwise) by the Authority
     or any Affiliate of the Authority or any person in privity with the
     Authority or any Affiliate of the Authority), directly or indirectly, or
     announce the offering of, any debt securities issued or guaranteed by the
     Authority (other than the Securities).

          (m) The Authority will not take, directly or indirectly, any action
     designed to or which has constituted or which might reasonably be expected
     to cause or result, under the Exchange Act or otherwise, in stabilization
     or manipulation of the price of any Security of the Authority to facilitate
     the sale or resale of the Securities.

          (n) The Authority agrees to pay the costs and expenses relating to the
     following matters: (i) the preparation of the Indentures and the
     Registration Rights Agreements, the issuance of the Securities and the fees
     of the Trustee; (ii) the preparation, printing or reproduction of the
     Preliminary Memorandum and Final Memorandum and each amendment or
     supplement to either of them; (iii) the printing (or reproduction) and
     delivery (including postage, air freight charges and charges for counting
     and packaging) of such copies of the Preliminary Memorandum and Final
     Memorandum, and all amendments or supplements to either of them, as may, in
     each case, be reasonably requested for use in connection with the offering
     and sale of the Securities; (iv) the preparation, printing, authentication,
     issuance and delivery of certificates for the Securities, including any
     stamp or transfer taxes in connection with the original issuance and sale
     of the Securities; (v) the printing (or reproduction) and delivery of this
     Purchase Agreement, any blue sky memorandum and all other agreements or
     documents printed (or reproduced) and delivered in connection with the
     offering of the Securities; (vi) any registration or qualification of the
     Securities for offer and sale under the securities or blue sky laws of the
     several states (including filing fees and the reasonable fees and expenses
     of counsel for the Initial Purchasers relating to such registration and
     qualification); (vii) admitting the Securities for trading in the PORTAL
     Market; (viii) the transportation and other expenses incurred by or on
     behalf of Authority representatives in connection with presentations to
     prospective purchasers of the Securities; (ix) the fees and expenses of the
     Authority's accountants and the fees and expenses of counsel (including
     local and special counsel) for the Authority; and (x) all other costs and
     expenses incident to the performance by the Authority of its obligations
     hereunder.

          (o) The Authority shall use the net proceeds received by it from the
     sale of the Securities pursuant to this Purchase Agreement in the manner
     specified in the Final Memorandum under the caption "Use of Proceeds."

     6. Conditions to the Obligations of the Initial Purchasers. The obligations
of the Initial Purchasers to purchase the Securities shall be subject to the
accuracy of the representations and warranties on the part of the Authority
contained herein at the Execution Time, the Closing Date and any settlement date
pursuant to Section 3 hereof to the accuracy of the statements of the Authority
made in any certificates pursuant to the provisions hereof, to the performance
by the Authority of its obligations hereunder and to the following additional
conditions:

          (a) The Authority shall have requested and caused Hogan & Hartson LLP,
     counsel for the Authority, to furnish to the Representatives its opinion,
     dated the Closing Date and addressed to the Representatives, to the effect
     that:

          (i) the Tribe is a federally recognized Indian tribe with authority to
          enter into and perform its obligations under the Agreements. The
          Constitution of the Tribe, as amended and restated in its entirety and
          approved on April 12, 1996 (the "Constitution"), is effective
          according to its terms and is the law of the Tribe;

          (ii) the Mohegan Tribal Council (the "Tribal Council") is the
          governing body of the Tribe, with power to bind the Tribe and to cause
          the Tribe to enter into the Agreements, except insofar as its power
          regarding agreements relating to gaming was delegated to the Authority
          by the 1995 Amendment, Article XIII, and Mohegan Ordinance No.
          95-7/15-1, "An Ordinance Establishing the Mohegan Tribal Gaming
          Authority" (the "Gaming Authority Ordinance"), which was adopted and
          made effective July 15, 1995. The Tribal Council and other officers of
          the Tribe and the Management Board and the other officers of the
          Authority that have approved, authorized the execution, and executed
          the Agreements and possess authority to execute the Agreements and to
          bind the Tribe and Authority thereto;

          (iii) the Senior Indenture and the Senior Subordinated Indenture have
          each been duly authorized, executed and delivered on behalf of the
          Tribe and the Authority, and each constitutes a valid and binding
          obligation of the Authority and the Tribe, enforceable against the
          Authority and the Tribe in accordance with its terms (except, as the
          enforcement thereof may be limited by bankruptcy, reorganization,
          insolvency, moratorium or other laws affecting creditors' rights
          (including, without limitation, the effect of statutory and other laws
          regarding fraudulent conveyances, fraudulent transfers and
          preferential transfers) and as may be limited by the exercise of
          judicial discretion and the application of principles of equity
          including, without limitation, requirements of good faith, fair
          dealing, conscionability and materiality (regardless of whether the
          Senior Indenture or Senior Subordinated Indenture is considered in a
          proceeding at law or in equity) and conform in all material respects
          to the descriptions thereof contained in the Final Memorandum under
          the caption "Description of Notes;" the Senior Securities and the
          Senior Subordinated Securities have


                                       13
<PAGE>
 
          each been duly authorized on behalf of the Authority and, assuming due
          execution, authentication, issuance and delivery in accordance with
          the provisions of the Senior Indenture or the Senior Subordinated
          Indenture, as the case may be, will each constitute a valid and
          binding obligation of the Authority entitled to the benefits of the
          Senior Indenture or the Senior Subordinated Indenture, as the case may
          be, in accordance with its terms, except as such enforceability may be
          limited by bankruptcy, insolvency, fraudulent conveyance,
          reorganization, moratorium and similar laws affecting creditors'

          (x) the choice of governing law by the Authority and the Tribe
          contained in the Agreements is in compliance in all material respects

          exercise of judicial discretion and the application of principles of
          equity including, without limitation, requirements of good faith, fair
          dealing, conscionability and materiality (regardless of whether the

          proceeding at law or in equity) and conform in all material respects
          to the description thereof contained in the Final Memorandum under the
          caption "Description of Notes."

     Such counsel shall also indicate that while they have not undertaken to
determine independently and do not assume any responsibility for, the accuracy,
completeness, or fairness of the statements in the Final Memorandum, that no
facts have come to their attention which cause them to believe that (i) the
Final Memorandum, as of its date and as of the date hereof, contained or
contains an untrue statement of a material fact or omitted or omits to state a
material fact necessary in order to make the statements therein, in the light of
the circumstances under which they were made, not misleading, (ii) there are any
legal or governmental proceedings pending or threatened against the Tribe and
the Authority that are required to be disclosed in the Final Memorandum, other
than those disclosed therein, or (iii) there are any contracts or documents of a
character required to be described in the Final Memorandum that are not
described or referred to therein; provided that in making the foregoing
statements (which shall not constitute an opinion), such counsel need not
express any views as to the financial statements and supporting schedules and
other financial and statistical information and data included in or omitted from
the Final Memorandum.

     In rendering such opinion, such counsel may rely as to matters of fact, to
the extent they deem proper on certificates of responsible officers of the
Authority and the Tribe. References to the Final Memorandum in this Section 6(a)
include any amendment or supplement thereto at the Closing Date.

          (b) The Authority shall have requested and caused Rome McGuigan
     Sabanosh, P.C., counsel for The Tribe, to furnish to the Representatives
     its opinion, dated the Closing Date and addressed to the Representatives,
     to the effect that:

          (i) the Tribe is a federally recognized Indian tribe, with full
          authority to enter into, and perform its obligations under, the
          Agreements. The Constitution of the Tribe, amended and restated in its
          entirety and approved on April 12, 1996 (the "Constitution"), was
          validly adopted by the Tribe, is effective according to its terms, and
          is the law of the Tribe;

          (ii) the Tribal Council (the "Tribal Council") is the governing body
          of the Tribe, with full power to bind the Tribe and to cause the Tribe
          to enter into the Agreements, except insofar as its power regarding
          agreements relating to gaming was delegated to the Authority by the
          1995 Amendment to the Constitution, Article XIII, and Mohegan
          Ordinance No. 95-7/15-1, "An Ordinance Establishing the Mohegan Tribal
          Gaming Authority" (the "Gaming Authority Ordinance"), which was
          adopted and made effective July 15, 1995. The Tribal Council and other
          officers of the Tribe and the


                                       17
<PAGE>
 
          Management Board and the other officers of the Authority that have
          approved, authorized the execution, and executed the Agreements, are
          the duly elected or appointed officers of the Tribe and the Authority,
          and possess full authority to execute the Agreements and to bind the
          Tribe and Authority thereto;

          (iii) the Gaming Authority Ordinance was validly adopted by the Tribal
          Council, and is the governing law of the Tribe. The Authority is a
          duly established and validly existing instrumentality of the Tribe;

          (iv) the Mohegan Compact has been duly entered into and validly
          authorized by the State of Connecticut and the Tribe, has been duly
          approved by the Secretary of the Interior of the United States, such
          approval has been duly published in the Federal Register, and no
          further action is required to make the Mohegan Compact effective;

          (v) the Mohegan Tribal Gaming Ordinance (the "Gaming Ordinance") was
          validly adopted by the Tribal Council, and validly approved by the
          National Indian Gaming Commission, and, as supplemented by the Gaming
          Authority Ordinance and the Gaming Disputes Court Ordinance, is the
          governing law of the Tribe;

          (vi) the Gaming Disputes Court of the Tribe (the "Gaming Disputes
          Court"), created by the Amendment to the Constitution and by Mohegan
          Ordinance No. 95-4 (adopted July 20, 1995), "An Ordinance Establishing
          the Gaming Disputes Court" (the "Gaming Disputes Court Ordinance"), is
          a validly established judicial entity of the Tribe, having exclusive
          jurisdiction for the Tribe over all disputes related to gaming on the
          lands of the Tribe. The adoption by the Tribal Council in the Gaming
          Disputes Ordinance of the rules of civil and appellate procedure, and
          professional and judicial conduct, to govern the Gaming Disputes
          Court, and the further adoption by the Tribal Council in "An Ordinance
          Concerning Procedures for Appeal to the Gaming Disputes Court,"
          Mohegan Ordinance No. 95-6 (adopted September 21, 1995) of procedures
          for certain appeals to the Gaming Disputes Court, are valid and
          effective acts of the Tribal Council, and those rules and procedures
          are the law of the Tribe;

          (vii) there is no requirement, under the Mohegan Compact, or the
          Gaming Authority Ordinance, or the Gaming Ordinance, or any other law
          of the Tribe, that any Note Holder, solely in his or her capacity as a
          Note Holder, apply for or receive any individual license, any
          individual certificate, or any other individual authorization from any
          federal, state, or tribal governmental authority, to acquire or retain
          the rights of a Note Holder under the Senior Indenture or the Senior
          Subordinated Indenture; and


                                       18
<PAGE>
 
          (viii) no consent, approval, authorization, filing with or order of
          any tribal or Connecticut court or governmental agency or body is
          required to be obtained or made by the Authority or the Tribe in
          connection with the execution, delivery or performance as of the date
          hereof by each of the Authority or the Tribe of the Senior Indenture,
          the Senior Subordinated Indenture, the Senior Registration Rights
          Agreement, the Senior Subordinated Registration Rights Agreement and
          the Concurrent Transactions, except (A) such as may be required under
          federal securities laws and regulations or under the blue sky or
          securities laws of any jurisdiction in connection with the purchase
          and sale of the Securities by the Initial Purchasers in the manner
          contemplated in this Purchase Agreement and the Final Memorandum and
          the Registration Rights Agreements (B) such as may be required to be
          obtained or made from or to the NIGC or its Chairman, the Secretary,
          or the BIA and such other approvals (specified in such opinion) as
          have been obtained.

          (c) Representatives shall have received from Latham & Watkins, counsel
     for the Initial Purchasers, such opinion or opinions, dated the Closing
     Date and addressed to the Representatives, with respect to the issuance and
     sale of the Securities, the Indentures, the Registration Rights Agreements,
     the Final Memorandum (as amended or supplemented at the Closing Date) and
     other related matters as the Representatives may reasonably require, and
     the Authority shall have furnished to such counsel such documents as they
     request for the purpose of enabling them to pass upon such matters.

          (d) The Authority shall have furnished to the Representatives a
     certificate of the Authority, signed by the Chairman of the Management
     Board dated the Closing Date to the effect that he has carefully examined
     the Final Memorandum, any amendment or supplement to the Final Memorandum
     and this Purchase Agreement and that:

          (i) the representations and warranties of the Authority in this
          Purchase Agreement are true and correct in all material respects on
          and as of the Closing Date with the same effect as if made on the
          Closing Date, and the Authority has complied with all the agreements
          and satisfied all the conditions on their its part to be performed or
          satisfied hereunder at or prior to the Closing Date;

          (ii) since the date of the most recent financial statements included
          in the Final Memorandum (exclusive of any amendment or supplement
          thereto), there has been no material adverse effect on the condition
          (financial or otherwise), prospects, earnings, business or properties
          of the Authority, whether or not arising from transactions on the
          ordinary course of business except as set forth in or contemplated by
          the Final Memorandum (exclusive of any amendment or supplement
          thereto); and

          (iii) no action has been taken and no statute, rule, regulation or
          order has been enacted, adopted or issued by any governmental agency
          which


                                       19
<PAGE>
 
          would, as of the date hereof, prevent the issuance of the Senior Notes
          and the Senior Subordinated Notes. No action, suit or proceeding had
          been commenced and is pending against or affecting or, to the best
          knowledge of the Authority, threatened against the Authority before
          any court or arbitrator or any governmental body, agency or official
          that, if adversely determined, could reasonably be expected to result
          in a material adverse effect on the Authority.

          (e) At the Execution Time, the Representatives shall have received
     from Arthur Andersen LLP, a letter, dated as of the Execution Time, in form
     and substance satisfactory to the Representatives, confirming that they are
     independent accountants within the meaning of the Act and the Exchange Act
     and the applicable rules and regulations thereunder, containing statements
     and information of the type ordinarily included in an accountant's "comfort
     letters" to Representatives, delivered according to Statement of Auditing
     Standards Nos. 72 and 76 (or any successor bulletins), with respect to the
     audited and unaudited financial statements and certain financial
     information contained in the Final Memorandum.

          (f) At the Closing Date, the Representatives shall have received from
     Arthur Andersen LLP, a "bring down comfort letter," dated as of the Closing
     Date.

          References to the Final Memorandum in Sections 6(e) - 6(f) include any
     amendment or supplement thereto at the date of the applicable letter.

          (g) Subsequent to the Execution Time or, if earlier, the dates as of
     which information is given in the Final Memorandum (exclusive of any
     amendment or supplement thereto), there shall not have been (i) any change
     or decrease specified in the letter or letters referred to in paragraphs
     (e) and (f) of this Section 6; or (ii) any change, or any development
     involving a prospective change, in or affecting the condition (financial or
     otherwise), prospects, earnings, business or properties of the Authority,
     except as set forth in or contemplated in the Final Memorandum (exclusive
     of any amendment or supplement thereto) the effect of which, in any case
     referred to in clause (i) or (ii) above, is, in the sole judgment of the
     Representatives, so material and adverse as to make it impractical or
     inadvisable to market the Securities as contemplated by the Final
     Memorandum (exclusive of any amendment or supplement thereto).

          (h) The Securities shall have been designated as PORTAL-eligible
     securities in accordance with the rules and regulations of the NASD, and
     the Securities shall be eligible for clearance and settlement through The
     Depositary Trust Company.

          (j) Prior to the Closing Date, the Authority shall have furnished to
     the Representatives such further information, certificates and documents as
     the Representatives may reasonably request.

          (k) The Authority shall have entered into (i) the Bank Credit
     Facility; (ii) the Registration Rights Agreements; (iii) the Construction
     Reserve Disbursement


                                       20
<PAGE>
 
     Agreement; (iv) the Indentures; and (v) the Initial Purchasers shall have
     received executed counterparts thereof.

          (l) The Authority shall have (i) purchased, simultaneous with the
     Offering, all of the Authority's 13 1/2% Senior Secured Notes due 2002 with
     Cash Flow Participation Interest (the "Existing Secured Notes") that were
     tendered pursuant to the Offer to Purchase and Consent Solicitation, dated
     as of January 15, 1999 (the "Offer to Purchase"), and the Initial
     Purchasers shall have received such documentation as they may reasonably
     request to evidence the purchase thereof and (ii) executed the Supplemental
     Indenture, between the Authority and First Union National Bank, as
     specified in the Offer to Purchase.

     If any of the conditions specified in this Section 6 shall not have been
fulfilled in all material respects when and as provided in this Purchase
Agreement, or if any of the opinions and certificates mentioned above or
elsewhere in this Purchase Agreement shall not be in all material respects
reasonably satisfactory in form and substance to the Representatives and counsel
for the Initial Purchasers, this Purchase Agreement and all obligations of the
Initial Purchasers hereunder may be canceled at, or at any time prior to, the
Closing Date by the Representatives. Notice of such cancellation shall be given
to the Authority in writing or by telephone or facsimile confirmed in writing.

     The documents required to be delivered by this Section 6 will be delivered
at the office of counsel for the Initial Purchasers, at 885 Third Avenue, New
York, New York 10022 on the Closing Date.

     7. Reimbursement of Expenses. If the sale of the Securities provided for
herein is not consummated because any condition to the obligations of the
Initial Purchasers set forth in Section 6 hereof is not satisfied, because of
any termination pursuant to Section 10 hereof or because of any refusal,
inability or failure on the part of the Authority to perform any agreement
herein or comply with any provision hereof other than by reason of a default by
any of the Initial Purchasers, the Authority will reimburse the Initial
Purchasers severally through Salomon Smith Barney Inc. on demand for all
out-of-pocket expenses (including reasonable fees and disbursements of counsel)
that shall have been incurred by them in connection with the proposed purchase
and sale of the Securities.

     8. Indemnification and Contribution.

     (a) The Authority agrees to indemnify and hold harmless each Initial
Purchaser, the directors, officers, employees and agents of each Initial
Purchaser and each person who controls any Initial Purchaser within the meaning
of either the Act or the Exchange Act against any and all losses, claims,
damages or liabilities, joint or several, to which they or any of them may
become subject under the Act, the Exchange Act or other federal or state
statutory law or regulation, at common law or otherwise, insofar as such losses,
claims, damages or liabilities (or actions in respect thereof) arise out of or
are based upon any untrue statement or alleged untrue statement of a material
fact contained in the Preliminary Memorandum, the Final Memorandum (or in any
supplement or amendment thereto) or any information provided by the Authority to
any holder or prospective purchaser of Securities pursuant to Section 5(h), or
in any amendment


                                       21

thereof or supplement thereto, or arise out of or are based upon the omission or
alleged omission to state therein a material fact required to be stated therein
or necessary to make the statements therein, in the light of the circumstances
under which they were made, not misleading, and agrees to reimburse each such
indemnified party, as incurred, for any legal or other expenses reasonably
incurred by them in connection with investigating or defending any such loss,
claim, damage, liability or action; provided, however, that the Authority will
not be liable in any such case to the extent that any such loss, claim, damage
or liability arises out of or is based upon any such untrue statement or alleged
untrue statement or omission or alleged omission made in the Preliminary
Memorandum or the Final Memorandum, or in any amendment thereof or supplement
thereto, in reliance upon and in conformity with written information relating to
an Initial Purchaser furnished to the Authority by or on behalf of any Initial
Purchaser through the Representatives specifically for inclusion therein; and
provided, further, that the foregoing indemnity agreement with respect to the
Final Memorandum shall not inure to the benefit of the Purchasers from whom the
person asserting or causing any such losses, claims, damages or liabilities
purchased Securities (or to the benefit of any person controlling any Initial
Purchaser or any directors, officers, employees and agents of any Initial
Purchaser), if a copy of the Final Memorandum (or the Final Memorandum as
amended or supplemented) (if the Authority shall have timely furnished the
Initial Purchasers with sufficient copies thereof) was not sent or given by or
on behalf of the Initial Purchasers to such person at or prior to the written
confirmation of the sale of the Securities to such person and if the Final
Memorandum (or the Final Memorandum as amended or supplemented) would have cured
the defect giving rise to such loss, claim, damage or liability. This indemnity
agreement will be in addition to any liability which the Authority may otherwise
have.

     (b) Each Initial Purchaser severally and not jointly agrees to indemnify
and hold harmless the Authority, its directors, officers, and each controlling
person within the meaning of either the Act or the Exchange Act, to the same
extent as the foregoing indemnity from the Authority to each Initial Purchaser,
but only with reference to written information relating to such Initial
Purchaser furnished to the Authority by or on behalf of such Initial Purchaser
through the Representatives specifically for inclusion in the Preliminary
Memorandum or the Final Memorandum (or in any amendment or supplement thereto).
This indemnity agreement will be in addition to any liability which any Initial
Purchaser may otherwise have. The Authority acknowledges that (i) the statements
set forth in the last paragraph of the cover page regarding the delivery of the
Securities, (ii) the legend on page (iii) concerning stabilization, syndicate
covering transactions and penalty bids and, the related disclosure under the
heading "Plan of Distribution," and (iii) the sentences related to concessions
and reallowances in the Preliminary Memorandum and the Final Memorandum,
constitute the only information furnished in writing by or on behalf of the
Initial Purchasers for inclusion in the Preliminary Memorandum or the Final
Memorandum (or in any amendment or supplement thereto).

     (c) Promptly after receipt by an indemnified party under this Section 8 of
notice of the commencement of any action, such indemnified party will, if a
claim in respect thereof is to be made against the indemnifying party under this
Section 8, notify the indemnifying party in writing of the commencement thereof;
but the failure so to notify the indemnifying party (i) will not relieve it from
liability under paragraph (a) or (b) above unless and to the extent it did not
otherwise learn of such action and such failure results in the forfeiture by the
indemnifying party of substantial rights and defenses; and (ii) will not, in any
event,


                                       22
<PAGE>
 
relieve the indemnifying party from any obligations to any indemnified party
other than the indemnification obligation provided in paragraph (a) or (b)
above. The indemnifying party shall be entitled to appoint counsel of the
indemnifying party's choice at the indemnifying party's expense to represent the
indemnified party in any action for which indemnification is sought (in which
case the indemnifying party shall not thereafter be responsible for the fees and
expenses of any separate counsel retained by the indemnified party or parties
except as set forth below); provided, however, that such counsel shall be
reasonably satisfactory to the indemnified party. Notwithstanding the
indemnifying party's election to appoint counsel to represent the indemnified
party in an action, the indemnified party shall have the right to employ
separate counsel, which counsel shall be reasonably satisfactory to the
indemnified party, and the indemnifying party shall bear the reasonable fees,
costs and expenses of such separate counsel if (i) the use of counsel chosen by
the indemnifying party to represent the indemnified party would present such
counsel with a conflict of interest, in which case the indemnifying party may
select another counsel subject to this clause (i); (ii) the actual or potential
defendants in, or targets of, any such action include both the indemnified party
and the indemnifying party and the indemnified party shall have reasonably
concluded that there may be legal defenses available to it and/or other
indemnified parties which are different from or additional to those available to
the indemnifying party; (iii) the indemnifying party shall not have employed
counsel reasonably satisfactory to the indemnified party to represent the
indemnified party within a reasonable time after notice of the institution of
such action; or (iv) the indemnifying party shall authorize the indemnified
party to employ separate counsel at the expense of the indemnifying party. An
indemnifying party will not, without the prior written consent of the
indemnified parties, settle or compromise or consent to the entry of any
judgment with respect to any pending or threatened claim, action, suit or
proceeding in respect of which indemnification or contribution may be sought
hereunder (whether or not the indemnified parties are actual or potential
parties to such claim or action) unless such settlement, compromise or consent
includes an unconditional release of each indemnified party from all liability
arising out of such claim, action, suit or proceeding.

     (d) In the event that the indemnity provided in paragraph (a) or (b) of
this Section 8 is unavailable to or insufficient to hold harmless an indemnified
party for any reason, the Authority and the Initial Purchasers agree to
contribute to the aggregate losses, claims, damages and liabilities (including
legal or other expenses reasonably incurred in connection with investigating or
defending same) (collectively "Losses") to which the Authority and one or more
of the Initial Purchasers may be subject in such proportion as is appropriate to
reflect the relative benefits received by the Authority on the one hand and by
the Initial Purchasers on the other from the offering of the Securities;
provided, however, that in no case shall any Initial Purchaser (except as may be
provided in any agreement among the Initial Purchasers relating to the offering
of the Securities) be responsible for any amount in excess of the purchase
discount or commission applicable to the Securities purchased by such Initial
Purchaser hereunder. If the allocation provided by the immediately preceding
sentence is unavailable for any reason, the Authority and the Initial Purchasers
shall contribute in such proportion as is appropriate to reflect not only such
relative benefits but also the relative fault of the Authority on the one hand
and of the Initial Purchasers on the other in connection with the statements or
omissions which resulted in such Losses, as well as any other relevant equitable
considerations. Benefits received by the Authority shall be deemed to be equal
to the total net proceeds from the offering (before deducting expenses) received
by them, and benefits received by the Initial Purchasers shall be deemed to be
equal to the total purchase discounts and commissions in each case set forth on
the


                                       23
<PAGE>
 
cover of the Final Memorandum. Relative fault shall be determined by reference
to, among other things, whether any untrue or any alleged untrue statement of a
material fact or the omission or alleged omission to state a material fact
relates to information provided by the Authority on the one hand or the Initial
Purchasers on the other, the intent of the parties and their relative knowledge,
information and opportunity to correct or prevent such untrue statement or
omission. The Authority and the Initial Purchasers agree that it would not be
just and equitable if contribution were determined by pro rata allocation or any
other method of allocation which does not take account of the equitable
considerations referred to above. Notwithstanding the provisions of this
paragraph (d), no person guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the Act) shall be entitled to contribution from any
person who was not guilty of such fraudulent misrepresentation. For purposes of
this Section 8, each person who controls an Initial Purchaser within the meaning
of either the Act or the Exchange Act and each director, officer, employee and
agent of an Initial Purchaser shall have the same rights to contribution as such
Initial Purchaser, and each person who controls the Authority within the meaning
of either the Act or the Exchange Act and each officer and director of the
Authority shall have the same rights to contribution as the Authority subject in
each case to the applicable terms and conditions of this paragraph (d).

     9. Default by an Initial Purchaser. If any one or more Initial Purchasers
shall fail to purchase and pay for any of the Securities agreed to be purchased
by such Initial Purchaser hereunder and such failure to purchase shall
constitute a default in the performance of its or their obligations under this
Purchase Agreement, the remaining Initial Purchasers shall be obligated
severally to take up and pay for (in the respective proportions which the amount
of Securities set forth opposite their names in Schedule I hereto bears to the
aggregate amount of Securities set forth opposite the names of all the remaining
Initial Purchasers) the Securities which the defaulting Initial Purchaser or
Initial Purchasers agreed but failed to purchase; provided, however, that in the
event that the aggregate amount of Securities which the defaulting Initial
Purchaser or Initial Purchasers agreed but failed to purchase shall exceed 10%
of the aggregate amount of Securities set forth in Schedule I hereto, the
remaining Initial Purchasers shall have the right to purchase all, but shall not
be under any obligation to purchase any, of the Securities, and if such
nondefaulting Initial Purchasers do not purchase all the Securities, this
Purchase Agreement will terminate without liability to any nondefaulting Initial
Purchaser or the Authority. In the event of a default by any Initial Purchaser
as set forth in this Section 9, the Closing Date shall be postponed for such
period, not exceeding five Business Days, as the Representatives shall determine
in order that the required changes in the Final Memorandum or in any other
documents or arrangements may be effected. Nothing contained in this Purchase
Agreement shall relieve any defaulting Initial Purchaser of its liability, if
any, to the Authority or any nondefaulting Initial Purchaser for damages
occasioned by its default hereunder.

     10. Termination. This Purchase Agreement shall be subject to termination in
the absolute discretion of the Representatives, by notice given to the Authority
prior to delivery of and payment for the Securities, if at any time prior to
such time (i) trading in securities generally on the New York Stock Exchange
shall have been suspended or limited or minimum prices shall have been
established on such Exchange; (ii) a banking moratorium shall have been declared
either by Federal or New York State authorities; or (iii) there shall have
occurred any outbreak or escalation of hostilities, declaration by the United
States of a national emergency or war or other calamity or crisis the effect of
which on financial markets is such as to make it, in


                                       24
<PAGE>
 
the sole judgment of the Representatives, impracticable or inadvisable to
proceed with the offering or delivery of the Securities as contemplated by the
Final Memorandum (exclusive of any amendment or supplement thereto).

     11. Representations and Indemnities to Survive. The respective agreements,
representations, warranties, indemnities and other statements of the Authority
or its officers and of the Initial Purchasers set forth in or made pursuant to
this Purchase Agreement will remain in full force and effect, regardless of any
investigation made by or on behalf of the Initial Purchasers or the Authority or
any of the officers, directors or controlling persons referred to in Section 8
hereof, and will survive delivery of and payment for the Securities. The
provisions of Sections 7 and 8 hereof shall survive the termination or
cancellation of this Purchase Agreement.

     12. Notices. All communications hereunder will be in writing and effective
only on receipt, and, if sent to the Representatives, will be mailed, delivered
or telefaxed to the Salomon Smith Barney Inc. General Counsel (fax no. (212)
816-7912) and confirmed to the General Counsel, Salomon Smith Barney Inc. at 388
Greenwich Street, New York, New York 10013 Attention: General Counsel; or, if

Tribal Gaming Authority, (fax no. (860) 204-7167), 1 Mohegan Sun Boulevard,

     13. No Personal Liability. Neither the Tribe nor any director, officer,
office holder, employee or agent, representative or member of the Authority or
the Tribe or holder of an ownership interest of the Authority or the Tribe, as
such in their individual capacities, shall have any liability for any
obligations of the Authority or the Tribe under this Purchase Agreement.

     14. Consent to Suit. The Tribe does not consent to the enforcement, levy,
or other execution of any judgment for money or other damages against any
assets, real or personal, of the Tribe, except that the Tribe and the Authority
consent to the enforcement and execution of any judgment, whether obtained as a
result of judicial, administrative, or arbitrational proceeding, against any
assets of the Authority. Subject to the foregoing, the Tribe and Authority waive
their respective sovereign immunity from unconsented suit, whether such suit be
brought in law or in equity, or in administrative proceedings or proceedings in
arbitration, to permit the commencement, maintenance, and enforcement of any
action, by any person with standing to maintain an action, to interpret or
enforce the terms of this Purchase Agreement and to enforce and execute any
judgment resulting therefrom against the Authority or the assets of the
Authority. Notwithstanding any provisions of law or canon of construction, the
Tribe and the Authority each intends this waiver to be interpreted liberally to
permit the full litigation of disputes arising under to out of this Purchase
Agreement. Without limiting the generality of the foregoing, the Tribe and the
Authority waive their immunity from unconsented suit to permit the maintenance
of the following actions:

     unconsented suit to permit any court of competent jurisdiction to (i)

     enforce the award of damages against the Authority owing as a consequence
     of a breach thereof, whether such award is the product of litigation,
     administrative proceedings or arbitration, (ii) determine whether any
     consent or approval of the Tribe or the Authority has been improperly


                                       25
<PAGE>
 
     granted or unreasonably withheld; (iii) enforce any judgment prohibiting
     the Tribe or the Authority from taking any action, or mandating or
     obligating the Tribe or the Authority to take any action, including a
     judgment compelling the Tribe or the Authority to submit to binding
     arbitration; and (iv) adjudicate any claim under the Indian Civil Rights
     Act of 1968, 25 U.S.C. ss. 1302 (or any successor statute).

          (b) Arbitration. The Tribe and the Authority each waive their immunity
     from unconsented suit to permit arbitrators, appointed and acting under the
     commercial arbitration rule of the American Arbitration Association,
     whenever and to the extent any agreement to submit a matter to arbitration
     is made by the Tribe or by the Authority, to (i) enforce and interpret the
     terms of this Purchase Agreement and to award and enforce the award of any
     damages against the Authority owing as a consequence thereof; (ii)
     determine whether any consent or approval of the Tribe or the Authority has
     been unreasonably withheld; and (iii) enforce any judgment prohibiting the
     Tribe or the Authority from taking any action, or mandating or obligating

                       Selling Restrictions for Offers and
                         Sales outside the United States

     (1)

     (a) The Securities have not been and will not be registered under the Act
and may not be offered or sold within the United States or to, or for the
account or benefit of, U.S. persons except in accordance with Regulation S under
the Act or pursuant to an exemption from the registration requirements of the
Act. Each Initial Purchaser represents and agrees that, except as otherwise
permitted by Section 4(a)(i) of the Agreement to which this is an exhibit, it
has offered and sold the Securities, and will offer and sell the Securities, (i)
as part of their distribution at any time; and (ii) otherwise until 40 days
after the later of the commencement of the offering and the Closing Date, only
in accordance with Rule 903 of Regulation S under the Act. Accordingly, each
Initial Purchaser represents and agrees that neither it, nor any of its
Affiliates nor any person acting on its or their behalf has engaged or will
engage in any directed selling efforts with respect to the Securities, and that
it and they have complied and will comply with the offering restrictions
requirement of Regulation S. Each Initial Purchaser agrees that, at or prior to
the confirmation of sale of Securities (other than a sale of Securities pursuant
to Section 4(a)(i) of the Agreement to which this is an exhibit), it shall have
sent to each distributor, dealer or person receiving a selling concession, fee
or other remuneration that purchases Securities from it during the distribution
compliance period a confirmation or notice to substantially the following
effect:

     "The Securities covered hereby have not been registered under the U.S.
     Securities Act of 1933 (the "Act") and may not be offered or sold within
     the United States or to, or for the account or benefit of, U.S. persons (i)
     as part of their distribution at any time or (ii) otherwise until 40 days
     after the later of the commencement of the offering and February __, 1999,
     except in either case in accordance with Regulation S or Rule 144A under
     the Act. Terms used above have the meanings given to them by Regulation S."

     (b) Each Initial Purchaser also represents and agrees that it has not
entered and will not enter into any contractual arrangement with any distributor
with respect to the distribution of the Securities, except with its Affiliates
or with the prior written consent of the Authority.

     (c) Terms used in this section have the meanings given to them by
Regulation S.

     (2) Each Initial Purchaser represents and agrees that (i) it has not
offered or sold, and will not offer or sell, in the United Kingdom, by means of
any document, any Securities other than to persons whose ordinary business it is
to buy or sell shares or debentures, whether as principal or as agent (except in
circumstances which do not constitute an offer to the public within the meaning
of the Companies Act 1989 of Great Britain); (ii) it has complied and will
comply with all applicable provisions of the Financial Services Act 1986 of the
United Kingdom


                                       A-1
<PAGE>
 
with respect to anything done by it in relation to the Securities in, from or
otherwise involving the United Kingdom; and (iii) it has only issued or passed
on and will only issue or pass on in the United Kingdom any document received by
it in connection with the issue of the Securities to a person who is of a kind
described in Article 9(3) of the Financial Services Act 1986 (Investment
Advertisements) (Exemptions) Order 1996 or is a person to whom the document may
otherwise lawfully be issued or passed on.

     Two Officers of the Authority shall sign the Senior Notes for the Authority
by manual or facsimile signature.

     If an Officer whose signature is on a Senior Note no longer holds that
office at the time a Senior Note is authenticated, the Senior Note shall
nevertheless be valid.

     A Senior Note shall not be valid until authenticated by the manual
signature of the Trustee. The signature shall be conclusive evidence that the
Senior Note has been authenticated under this Indenture.

     The Trustee shall, upon a written order of the Authority signed by two
Officers of the Authority (an "Authentication Order"), authenticate Senior Notes
for original issue up to the aggregate principal amount not to exceed
$200,000,000 (other than as provided in Section 2.07 hereof) in one or more
series, which order shall specify whether such notes are Initial Senior Notes or

     The Senior Notes shall be issued only in fully registered form, without
coupons and only in denominations of $1,000 and any integral multiple thereof.
All Senior Notes issued under this Indenture shall vote and consent together on
all matters as one class and no series of Senior Notes will have the right to

to authenticate Senior Notes. An authenticating agent may authenticate Senior
Notes whenever the Trustee may do so. Each reference in this Indenture to

<PAGE>
 
additional paying agents. The term "Registrar" includes any co-registrar and the
term "Paying Agent" includes any additional paying agent. The Authority may
change any Paying Agent or Registrar without notice to any Holder. The Authority
shall notify the Trustee in writing of the name and address of any Agent not a
party to this Indenture. If the Authority fails to appoint or maintain another
entity as Registrar or Paying Agent, the Trustee shall act as such. The

Registrar.

act as Depositary with respect to the Global Senior Notes.

Holders or the Trustee all money held by the Paying Agent for the payment of
principal, premium or Additional Interest, if any, or interest on the Senior
Notes, and will notify the Trustee of any default by the Authority in making any
such payment. While any such default continues, the Trustee may require a Paying
Agent to pay all money held by it to the Trustee. The Authority at any time may
require a Paying Agent to pay all money held by it to the Trustee. Upon payment
over to the Trustee, the Paying Agent (if other than the Authority or a
Restricted Subsidiary or an Affiliate) shall have no further liability for the
money. If the Authority or a Restricted Subsidiary acts as Paying Agent, it
shall segregate and hold in a separate trust fund for the benefit of the Holders
all money held by it as Paying Agent. Upon any bankruptcy or reorganization
proceedings relating to the Authority, the Trustee shall serve as Paying Agent
for the Senior Notes.

     The Trustee shall preserve in as current a form as is reasonably
practicable the most recent list available to it of the names and addresses of
all Holders and shall otherwise comply with TIA ss. 312(a). If the Trustee is

Business Days before each interest payment date and at such other times as the
Trustee may request in writing, a list in such form and as of such date as the
Trustee may reasonably require of the names and addresses of the Holders of
Senior Notes and the Authority shall otherwise comply with TIA ss. 312(a).

     Holder thereof for an Unrestricted Definitive Senior Note or transferred to
     a Person or Persons who take delivery thereof in the form of an
     Unrestricted Definitive Senior Note if:

               (A) such exchange or transfer is effected pursuant to the
          Exchange Offer in accordance with the Senior Registration Rights
          Agreement and the Holder, in the case of an exchange, or the
          transferee, in the case of a transfer, certifies in the applicable
          Letter of Transmittal that it is not (1) a broker-dealer, (2) a Person
          participating in the distribution of the Senior Exchange Notes or (3)
          a Person who is an affiliate (as defined in Rule 144) of the
          Authority;

               (B) any such transfer is effected pursuant to the Shelf
          Registration Statement in accordance with the Senior Registration
          Rights Agreement;

               (C) any such transfer is effected by a Broker-Dealer pursuant to
          the Exchange Offer Registration Statement in accordance with the
          Senior Registration Rights Agreement; or

               (D) the Registrar receives the following:

                    (1) if the Holder of such Restricted Definitive Senior Notes
               proposes to exchange such Senior Notes for an Unrestricted
               Definitive Senior Note, a certificate from such Holder in the
               form of Exhibit C hereto, including the certifications in item
               (1)(d) thereof; or

                    (2) if the Holder of such Restricted Definitive Senior Notes
               proposes to transfer such Senior Notes to a Person who shall take
               delivery thereof in the form of an Unrestricted Definitive Senior
               Note, a certificate from such Holder in the form of Exhibit B
               hereto, including the certifications in item (4) thereof;

          and, in each such case set forth in this subparagraph (D), if the
          Registrar so requests, an Opinion of Counsel in form reasonably
          acceptable to the Authority to the effect that such exchange or
          transfer is in compliance with the Securities Act and that the
          restrictions on transfer contained herein and in the Private Placement
          Legend are no longer required in order to maintain compliance with the
          Securities Act.

          (iii) Unrestricted Definitive Senior Notes to Unrestricted Definitive
     Senior Notes. A Holder of Unrestricted Definitive Senior Notes may transfer
     such Senior Notes to a Person who takes delivery thereof in the form of an
     Unrestricted Definitive Senior Note. Upon receipt of a request to register
     such a transfer, the Registrar shall register the Unrestricted Definitive
     Senior Notes pursuant to the instructions from the Holder thereof.

     (f) Exchange Offer. Upon the occurrence of an Exchange Offer in accordance
with the Senior Registration Rights Agreement, the Authority shall issue and,
upon receipt of an Authentication Order in accordance with Section 2.02, the
Trustee shall authenticate (i) one or more Unrestricted Global Senior Notes in
an aggregate principal amount equal to the principal amount of the beneficial
interests in the Restricted Global Senior Notes tendered for acceptance by
Persons that certify in the applicable Letters of Transmittal that (x) they are
not broker-dealers, (y) they are not participating in a distribution of the
Senior Exchange Notes and (z) they are not affiliates (as defined in Rule 144)
of the Authority, and accepted for exchange in the Exchange Offer and (ii)

<PAGE>
 
exchange in the Exchange Offer. Concurrently with the issuance of such Senior
Notes, the Trustee shall cause the aggregate principal amount of the applicable
Restricted Global Senior Notes to be reduced accordingly, and the Authority
shall execute and the Trustee shall authenticate and deliver to the Persons
designated by the Holders of Definitive Senior Notes so accepted Definitive
Senior Notes in the appropriate principal amount.

     (g) Legends. The following legends shall appear on the face of all Global
Senior Notes and Definitive Senior Notes issued under this Indenture unless
specifically stated otherwise in the applicable provisions of this Indenture.

          (i) Private Placement Legend.

          (B) Notwithstanding the foregoing, any Global Senior Note or

     (c)(iii), (c)(iv), (d)(ii), (d)(iii), (e)(ii), (e)(iii) or

     (f) to this Section 2.06 (and all Senior Notes issued in exchange therefor
     or substitution thereof) shall not bear the Private Placement Legend.

          (ii) Global Senior Note Legend. Each Global Senior Note shall bear a
     legend in substantially the following form:

"THIS GLOBAL NOTE IS HELD BY THE DEPOSITARY (AS DEFINED IN THE INDENTURE

          (iii) Regulation S Temporary Global Senior Note Legend. The Regulation
     S Temporary Global Senior Note shall bear a legend in substantially the
     following form:

"THE RIGHTS ATTACHING TO THIS REGULATION S TEMPORARY GLOBAL NOTE, AND THE
CONDITIONS AND PROCEDURES GOVERNING ITS EXCHANGE FOR CERTIFICATED NOTES, ARE AS
SPECIFIED IN THE INDENTURE (AS DEFINED HEREIN). NEITHER THE HOLDER NOR THE
BENEFICIAL OWNERS OF THIS REGULATION S TEMPORARY GLOBAL NOTE SHALL BE ENTITLED
TO RECEIVE PAYMENT OF INTEREST HEREON."

     (h) Cancellation and/or Adjustment of Global Senior Notes. At such time as
all beneficial interests in a particular Global Senior Note have been exchanged
for Definitive Senior Notes or a particular Global Senior Note has been
redeemed, repurchased or canceled in whole and not in part, each such Global
Senior Note shall be returned to or retained and canceled by the Trustee in
accordance with Section 2.11 hereof. At any time prior to such cancellation, if
any beneficial interest in a Global Senior Note is exchanged for or transferred
to a Person who will take delivery thereof in the form of a beneficial interest
in another Global Senior Note or for Definitive Senior Notes, the principal
amount of Senior Notes represented by such Global Senior Note shall be reduced
accordingly and an endorsement shall be made on such Global Senior Note by the
Trustee or by the Depositary at the direction of the Trustee to reflect such
reduction; and if the beneficial interest is being exchanged for or transferred
to a Person who will take delivery thereof in the form of a beneficial interest
in another Global Senior Note, such other Global Senior Note shall be increased
accordingly and an endorsement shall be made on such Global Senior Note by the
Trustee or by the Depositary at the direction of the Trustee to reflect such
increase.

     (i) General Provisions Relating to Transfers and Exchanges.

          (i) To permit registrations of transfers and exchanges, the Authority
     shall execute and the Trustee shall authenticate Global Senior Notes and
     Definitive Senior Notes upon the Authority's order or at the Registrar's
     request.

          (ii) No service charge shall be made to a holder of a beneficial
     interest in a Global Senior Note or to a Holder of a Definitive Senior Note
     for any registration of transfer or exchange, but the Authority may require
     payment of a sum sufficient to cover any transfer tax or similar
     governmental charge payable in connection therewith (other than any such
     transfer taxes or similar governmental


                                       34
<PAGE>
 
     charge payable upon exchange or transfer pursuant to Sections 2.10, 3.06,
     3.10, 4.10, 4.15 and 9.05 hereof).

          (iii) The Registrar shall not be required to register the transfer of
     or exchange any Senior Note selected for redemption in whole or in part,
     except the unredeemed portion of any Senior Note being redeemed in part.

          (iv) All Global Senior Notes and Definitive Senior Notes issued upon
     any registration of transfer or exchange of Global Senior Notes or
     Definitive Senior Notes shall be the valid obligations of the Authority,
     evidencing the same debt, and entitled to the same benefits under this
     Indenture, as the Global Senior Notes or Definitive Senior Notes
     surrendered upon such registration of transfer or exchange.

          (v) The Authority shall not be required (A) to issue, to register the
     transfer of or to exchange any Senior Notes during a period beginning at
     the opening of business 15 days before the day of any selection of Senior
     Notes for redemption under Section 3.02 hereof and ending at the close of
     business on the day of selection, (B) to register the transfer of or to
     exchange any Senior Note so selected for redemption in whole or in part,
     except the unredeemed portion of any Senior Note being redeemed in part or
     (C) to register the transfer of or to exchange a Senior Note between a
     record date and the next succeeding Interest Payment Date.

          (vi) Prior to due presentment for the registration of a transfer of
     any Senior Note, the Trustee, any Agent and the Authority may deem and
     treat the Person in whose name any Senior Note is registered as the
     absolute owner of such Senior Note for the purpose of receiving payment of
     principal of and interest on such Senior Notes and for all other purposes,
     and none of the Trustee, any Agent or the Authority shall be affected by
     notice to the contrary.

          (vii) The Trustee shall authenticate Global Senior Notes and
     Definitive Senior Notes in accordance with the provisions of Section 2.02
     hereof.

          (viii) All certifications, certificates and Opinions of Counsel
     required to be submitted to the Registrar pursuant to this Section 2.06 to
     effect a registration of transfer or exchange may be submitted by
     facsimile.

Section 2.07. Replacement Senior Notes.

     If any mutilated Senior Note is surrendered to the Trustee or the Authority
and the Trustee receives evidence to its satisfaction of the destruction, loss
or theft of any Senior Note, the Authority shall issue and the Trustee, upon
receipt of an Authentication Order, shall authenticate a replacement Senior Note
in accordance with the requirements of the Trustee set forth herein. If required
by the Trustee or the Authority, an indemnity bond must be supplied by the
Holder that is sufficient in the judgment of the Trustee and the Authority to
protect the Authority, the Trustee, any Agent and any authenticating agent from
any loss that any of them may suffer if a Senior Note is replaced. The Authority
may charge for its expenses in replacing a Senior Note.

     Every replacement Senior Note is an additional obligation of the Authority
and shall be entitled to all of the benefits of this Indenture equally and
proportionately with all other Senior Notes duly issued hereunder.

                                                                    Senior Notes
<PAGE>
 
Section 2.08.  Outstanding Senior Notes.

     The Senior Notes outstanding at any time are all the Senior Notes
authenticated by the Trustee except for those canceled by it, those delivered to
it for cancellation, those reductions in the interest in a Global Senior Note
effected by the Trustee in accordance with the provisions hereof, and those
described in this Section as not outstanding. Except as set forth in Section
2.09 hereof, a Senior Note does not cease to be outstanding because the
Authority or an Affiliate of the Authority holds the Senior Note.

     If a Senior Note is replaced pursuant to Section 2.07 hereof, it ceases to
be outstanding unless the Trustee receives proof satisfactory to it that the
replaced Senior Note is held by a bona fide purchaser.

     If the principal amount of any Senior Note is considered paid under Section
4.01 hereof, it ceases to be outstanding and interest on it ceases to accrue.

     If the Paying Agent (other than the Authority, a Subsidiary or an Affiliate
of any thereof) holds, on a redemption date or maturity date, money sufficient
to pay Senior Notes payable on that date, then on and after that date such
Senior Notes shall be deemed to be no longer outstanding and shall cease to
accrue interest.

Section 2.09. Treasury Senior Notes.

     In determining whether the Holders of the required principal amount of
Senior Notes have concurred in any direction, waiver or consent, Senior Notes
owned by the Authority, or by any Person directly or indirectly controlling or
controlled by or under direct or indirect common control with the Authority,
shall be considered as though not outstanding, except that for the purposes of
determining whether the Trustee shall be protected in relying on any such
direction, waiver or consent, only Senior Notes that the Trustee actually knows
are so owned shall be so disregarded.

Section 2.10. Temporary Senior Notes.

     Until certificates representing Senior Notes are ready for delivery, the
Authority may prepare and the Trustee, upon receipt of an Authentication Order,
shall authenticate temporary Senior Notes. Temporary Senior Notes shall be
substantially in the form of certificated Senior Notes but may have variations
that the Authority considers appropriate for temporary Senior Notes and as shall
be reasonably acceptable to the Trustee. Without unreasonable delay, the
Authority shall prepare and the Trustee shall authenticate definitive Senior
Notes in exchange for temporary Senior Notes.

     Holders of temporary Senior Notes shall be entitled to all of the benefits
of this Indenture.

Section 2.11. Cancellation.

     The Authority at any time may deliver Senior Notes to the Trustee for
cancellation. The Registrar and Paying Agent shall forward to the Trustee any
Senior Notes surrendered to them for registration of transfer, exchange or
payment. The Trustee and no one else shall cancel all Senior Notes surrendered
for registration of transfer, exchange, payment, replacement or cancellation and
shall destroy canceled Senior Notes (subject to the record retention requirement
of the Exchange Act). Certification of the destruction of all canceled Senior
Notes shall be delivered to the Authority. The Authority may not issue new
Senior Notes to replace Senior Notes that it has paid or that have been
delivered to the Trustee for cancellation.

<PAGE>
 
Section 2.12. Defaulted Interest.

     If the Authority defaults in a payment of interest on the Senior Notes, it
shall pay the defaulted interest in any lawful manner plus, to the extent
lawful, interest payable on the defaulted interest, to the Persons who are
Holders on a subsequent special record date, in each case at the rate provided
in the Senior Notes and in Section 4.01 hereof. The Authority shall notify the
Trustee in writing of the amount of defaulted interest proposed to be paid on
each Senior Note and the date of the proposed payment. The Authority shall fix
or cause to be fixed each such special record date and payment date, provided
that no such special record date shall be less than 10 days prior to the related
payment date for such defaulted interest. At least 15 days before the special
record date, the Authority (or, upon the written request of the Authority, the
Trustee in the name and at the expense of the Authority) shall mail or cause to
be mailed to Holders a notice that states the special record date, the related
payment date and the amount of such interest to be paid.

Section 2.13. CUSIP Numbers.

     The Authority in issuing the Senior Notes may use "CUSIP" numbers (if then
generally in use), and, if so, the Trustee shall use CUSIP numbers in notices of
redemption as a convenience to Holders; provided that any such notice may state
that no representation is made as to the correctness of such numbers either as
printed on the Senior Notes or as contained in any notice of a redemption and
that reliance may be placed only on the other identification numbers printed on
the Senior Notes, and any such redemption shall not be affected by any defect in
or the omission of such numbers. The Authority will promptly notify the Trustee
of any change in the CUSIP numbers.

                                    ARTICLE 3
                            REDEMPTION AND PREPAYMENT

Section 3.01. Notices to Trustee.

     If the Authority elects to redeem Senior Notes pursuant to the optional
redemption provisions of Section 3.07 hereof, it shall furnish to the Trustee,
at least 30 days but not more than 60 days before a redemption date, an
Officers' Certificate setting forth (i) the clause of this Indenture pursuant to
which the redemption shall occur, (ii) the redemption date, (iii) the principal
amount of Senior Notes to be redeemed and (iv) the redemption price.

Section 3.02. Selection of Senior Notes to Be Redeemed.

     If less than all of the Senior Notes are to be redeemed or purchased in an
offer to purchase at any time, the Trustee shall select the Senior Notes to be
redeemed or purchased among the Holders of the Senior Notes in compliance with
the requirements of the principal national securities exchange, if any, on which
the Senior Notes are listed or, if the Senior Notes are not so listed, on a pro
rata basis, by lot or in accordance with any other method the Trustee considers
fair and appropriate. In the event of partial redemption by lot, the particular
Senior Notes to be redeemed shall be selected, unless otherwise provided herein,
not less than 30 nor more than 60 days prior to the redemption date by the
Trustee from the outstanding Senior Notes not previously called for redemption.

     The Trustee shall promptly notify the Authority in writing of the Senior
Notes selected for redemption and, in the case of any Senior Note selected for
partial redemption, the principal amount thereof to be redeemed. Senior Notes
and portions of Senior Notes selected shall be in amounts of $1,000 or whole
multiples of $1,000, except that if all of the Senior Notes of a Holder are to
be 


                                       37
                                                                    Senior Notes
<PAGE>
 
redeemed, the entire outstanding amount of Senior Notes held by such Holder,
even if not a multiple of $1,000, shall be redeemed. Except as provided in the
preceding sentence, provisions of this Indenture that apply to Senior Notes
called for redemption also apply to portions of Senior Notes called for
redemption.

Section 3.03. Notice of Redemption.

     Subject to the provisions of Section 3.10 hereof, at least 30 days but not
more than 60 days before a redemption date, the Authority shall mail or cause to
be mailed, by first class mail, a notice of redemption to each Holder whose
Senior Notes are to be redeemed at its registered address.

     The notice shall identify the Senior Notes to be redeemed and shall state:

     (a) the redemption date;

     (b) the redemption price;

     (c) if any Senior Note is being redeemed in part, the portion of the
principal amount of such Senior Note to be redeemed and that, after the
redemption date upon surrender of such Senior Note, a new Senior Note or Senior
Notes in principal amount equal to the unredeemed portion shall be issued upon
cancellation of the original Senior Note;

     (d) the name and address of the Paying Agent;

     (e) that Senior Notes called for redemption must be surrendered to the
Paying Agent to collect the redemption price;

     (f) that, unless the Authority defaults in making such redemption payment,
interest on Senior Notes called for redemption ceases to accrue on and after the
redemption date;

     (g) the paragraph of the Senior Notes and/or Section of this Indenture
pursuant to which the Senior Notes called for redemption are being redeemed; and

     (h) that no representation is made as to the correctness or accuracy of the
CUSIP number, if any, listed in such notice or printed on the Senior Notes.

     At the Authority's request, the Trustee shall give the notice of redemption
in the Authority's name and at its expense; provided, however, that the
Authority shall have delivered to the Trustee, at least 45 days prior to the
redemption date (unless a shorter period shall be satisfactory to the Trustee),
an Officers' Certificate requesting that the Trustee give such notice and
setting forth the information to be stated in such notice as provided in the
preceding paragraph.

Section 3.04.  Effect of Notice of Redemption.

     Once notice of redemption is mailed in accordance with Section 3.03 hereof,
Senior Notes called for redemption become irrevocably due and payable on the
redemption date at the redemption price. A notice of redemption may not be
conditional.

                                       38
                                                                    Senior Notes
<PAGE>
 
Section 3.05.  Deposit of Redemption Price.

     One Business Day prior to the redemption date, the Authority shall deposit
with the Trustee or with the Paying Agent money sufficient to pay the redemption
price of and accrued interest on all Senior Notes to be redeemed on that date.
The Trustee or the Paying Agent shall promptly return to the Authority any money
deposited with the Trustee or the Paying Agent by the Authority in excess of the
amounts necessary to pay the redemption price of, and accrued interest on, all
Senior Notes to be redeemed.

     If the Authority complies with the provisions of the preceding paragraph,
on and after the redemption date, interest shall cease to accrue on the Senior
Notes or the portions of Senior Notes called for redemption. If a Senior Note is
redeemed on or after an interest record date but on or prior to the related
interest payment date, then any accrued and unpaid interest shall be paid to the
Person in whose name such Senior Note was registered at the close of business on
such record date. If any Senior Note called for redemption shall not be so paid
upon surrender for redemption because of the failure of the Authority to comply
with the preceding paragraph, interest shall be paid on the unpaid principal,
from the redemption date until such principal is paid, and to the extent lawful
on any interest not paid on such unpaid principal, in each case at the rate
provided in the Senior Notes and in Section 4.01 hereof.

Section 3.06.  Senior Notes Redeemed in Part.

     Upon surrender of a Senior Note that is redeemed in part, the Authority
shall issue and, upon the Authority's written request, the Trustee shall
authenticate for the Holder at the expense of the Authority a new Senior Note
equal in principal amount to the unredeemed portion of the Senior Note
surrendered.

Section 3.07.  Optional Redemption.

     The Authority may redeem all or a part of these Senior Notes upon not less
than 30 nor more than 60 days' notice, at a redemption price (expressed as
percentages of principal amount) equal to 100% of the principal amount thereof
plus the Applicable Premium, if any, plus accrued and unpaid interest thereon,
if any, to the applicable redemption date.

     Any redemption pursuant to this Section 3.07 shall be made pursuant to the
provisions of Section 3.01 through 3.06 hereof.

Section 3.08.  Redemption Pursuant to Gaming Law

     (a) Notwithstanding any other provisions of this Article 3, if any Gaming
Regulatory Authority requires that a Holder or beneficial owner of the Senior
Notes must be licensed, qualified or found suitable under any applicable gaming
laws in order to maintain any gaming license or franchise of the Authority under
any applicable gaming laws, and the Holder or beneficial owner fails to apply
for a license, qualification or finding of suitability within 30 days after
being requested to do so by such Gaming Regulatory Authority (or such lesser
period that may be required by such Gaming Regulatory) or if such Holder or
beneficial owner is not so licensed, qualified or found suitable, the Authority
has the right, at its option, (i) to require such Holder or beneficial owner to
dispose of such Holder's or beneficial owner's Senior Notes within 30 days of
receipt of such finding by the applicable Gaming Regulatory Authority (or such
earlier date as may be required by the applicable Gaming Regulatory Authority);
or (ii) to call for redemption of the Senior Notes of such Holder or beneficial
owner at a redemption price equal to the lesser of (1) the principal amount
thereof or (2) the price at which such 


                                       39
                                                                    Senior Notes
<PAGE>
 
Holder or beneficial owner acquired the Senior Notes or (3) the current market
price of the Senior Notes, together with, in each case, accrued and unpaid
interest and Additional Interest, if any, to the earlier of the date of
redemption or the date of the finding of unsuitability by such Gaming Regulatory
Authority, which may be less than 30 days following the notice of redemption if
so ordered by such Gaming Regulatory Authority.

     (b) In connection with any redemption pursuant to this Section 3.08, and
except as may be required by a Gaming Regulatory Authority, the Authority shall
comply with Sections 3.01 through 3.06 hereof.

     (c) The Authority shall not be required to pay or reimburse any Holder or
beneficial owner of Senior Notes who is required to apply for such license,
qualification or finding of suitability for the costs of the licensure or
investigation for such qualification or finding of suitability. Such expenses
shall be the obligation of such Holder or beneficial owner.

Section 3.09.  Mandatory Redemption.

     The Authority shall not be required to make mandatory redemption payments
with respect to the Senior Notes.

Section 3.10. Offer to Purchase by Application of Excess Proceeds.

     In the event that, pursuant to Section 4.10 hereof, the Authority shall be
required to commence an offer to all Holders to purchase Senior Notes (an "Asset
Sale Offer"), it shall follow the procedures specified below.

     The Asset Sale Offer shall remain open for a period of 20 Business Days
following its commencement and no longer, except to the extent that a longer
period is required by applicable law (the "Offer Period"). No later than five
Business Days after the termination of the Offer Period (the "Purchase Date"),
the Authority shall purchase the principal amount of Senior Notes required to be
purchased pursuant to Section 4.10 hereof (the "Offer Amount") or, if less than
the Offer Amount has been tendered, all Senior Notes tendered in response to the
Asset Sale Offer. Payment for any Senior Notes so purchased shall be made in the
same manner as interest payments are made.

     If the Purchase Date is on or after an interest record date and on or
before the related interest payment date, any accrued and unpaid interest shall
be paid to the Person in whose name a Senior Note is registered at the close of
business on such record date, and no additional interest shall be payable to
Holders who tender Senior Notes pursuant to the Asset Sale Offer.

     Upon the commencement of an Asset Sale Offer, the Authority shall send, by
first class mail, a notice to the Trustee and each of the Holders, with a copy
to the Trustee. The notice shall contain all instructions and materials
necessary to enable such Holders to tender Senior Notes pursuant to the Asset
Sale Offer. The Asset Sale Offer shall be made to all Holders. The notice, which
shall govern the terms of the Asset Sale Offer, shall state:

     (a) that the Asset Sale Offer is being made pursuant to this Section 3.10
and Section 4.10 hereof and the length of time the Asset Sale Offer shall remain
open;

     (b) the Offer Amount, the purchase price and the Purchase Date;

                                       40
                                                                    Senior Notes
<PAGE>
 
     (c) that any Senior Note not tendered or accepted for payment shall
continue to accrue interest;

     (d) that, unless the Authority defaults in making such payment, any Senior
Note accepted for payment pursuant to the Asset Sale Offer shall cease to accrue
interest after the Purchase Date;

     (e) that Holders electing to have a Senior Note purchased pursuant to an
Asset Sale Offer may elect to have Senior Notes purchased in integral multiples
of $1,000 only;

     (f) that Holders electing to have a Senior Note purchased pursuant to any
Asset Sale Offer shall be required to surrender the Senior Note, with the form
entitled "Option of Holder to Elect Purchase" on the reverse of the Senior Note
completed, or transfer by book-entry transfer, to the Authority, a depositary,
if appointed by the Authority, or a paying agent at the address specified in the
notice at least three days before the Purchase Date;

     (g) that Holders shall be entitled to withdraw their election if the
Authority, the Depositary or the paying agent, as the case may be, receives, not
later than the expiration of the Offer Period, a telegram, telex, facsimile
transmission or letter setting forth the name of the Holder, the principal
amount of the Senior Note the Holder delivered for purchase and a statement that
such Holder is withdrawing his election to have such Senior Note purchased;

     (h) that, if the aggregate principal amount of Senior Notes surrendered by
Holders exceeds the Offer Amount, the Authority shall select the Senior Notes to
be purchased on a pro rata basis (with such adjustments as may be deemed
appropriate by the Authority so that only Senior Notes in denominations of
$1,000, or integral multiples thereof, shall be purchased); and

     (i) that Holders whose Senior Notes were purchased only in part shall be
issued new Senior Notes equal in principal amount to the unpurchased portion of
the Senior Notes surrendered (or transferred by book-entry transfer).

     On or before the Purchase Date, the Authority shall, to the extent lawful,
accept for payment, on a pro rata basis to the extent necessary, the Offer
Amount of Senior Notes or portions thereof tendered pursuant to the Asset Sale
Offer, or if less than the Offer Amount has been tendered, all Senior Notes
tendered, and shall deliver to the Trustee an Officers' Certificate stating that
such Senior Notes or portions thereof were accepted for payment by the Authority
in accordance with the terms of this Section 3.10. The Authority, the Depositary
or the Paying Agent, as the case may be, shall promptly (but in any case not
later than five Business Days after the Purchase Date) mail or deliver to each
tendering Holder an amount equal to the purchase price of the Senior Notes
tendered by such Holder and accepted by the Authority for purchase, and the
Authority shall promptly issue a new Senior Note, and the Trustee, upon written
request from the Authority shall authenticate and mail or deliver such new
Senior Note to such Holder, in a principal amount equal to any unpurchased
portion of the Senior Note surrendered. Any Senior Note not so accepted shall be
promptly mailed or delivered by the Authority to the Holder thereof. The
Authority shall publicly announce the results of the Asset Sale Offer on the
Purchase Date.

     Other than as specifically provided in this Section 3.10, any purchase
pursuant to this Section 3.10 shall be made pursuant to the provisions of
Sections 3.01 through 3.06 hereof.

surrendered for registration of transfer or for exchange and where notices and
demands to or upon the Authority in respect of the Senior Notes and this
Indenture may be served. The Authority shall give prompt written notice to the
Trustee of the location, and any change in the location, of such office or
agency. If at any time the Authority shall fail to maintain any such required
office or agency or shall fail to furnish the Trustee with the address thereof,
such presentations, surrenders, notices and demands may be made or served at the
Corporate Trust Office of the Trustee.

     (b) The Authority may also from time to time designate one or more other
offices or agencies where the Senior Notes may be presented or surrendered for
any or all such purposes and may from time to time rescind such designations;
provided, however, that no such designation or rescission shall in any manner
relieve the Authority of its obligation to maintain an office or agency in the

shall give prompt written notice to the Trustee of any such designation or
rescission and of any change in the location of any such other office or agency.

Trustee as one such office or agency of the Authority in accordance with Section

          operations of the Authority and its Restricted Subsidiaries separate
          from the financial condition and results of operations of the
          Unrestricted Subsidiaries of the Authority, to the extent that would

     (e) The Authority shall at all times comply with TIA ss. 314(a).

Section 4.04.  Compliance Certificate.

     (a) The Authority shall deliver to the Trustee, within 90 days after the

activities of the Authority and its Subsidiaries during the preceding fiscal
year has been made under the supervision of the signing Officers with a view to

its obligations under this Indenture, and further stating, as to each such
Officer signing such certificate, that to the best of his or her knowledge the
Authority has kept, observed, performed and fulfilled each and every covenant
contained in this Indenture and is not in default in the performance or
observance of any of the terms, provisions and conditions of this Indenture (or,

<PAGE>
 
(who shall be a firm of established national reputation) that in making the
examination necessary for certification of such financial statements, nothing
has come to their attention that would lead them to believe that the Authority
has violated any provisions of Article 4 or Article 5 hereof or, if any such
violation has occurred, specifying the nature and period of existence thereof,
it being understood that such accountants shall not be liable directly or
indirectly to any Person for any failure to obtain knowledge of any such
violation.

     (c) The Authority shall, so long as any of the Senior Notes are
outstanding, deliver to the Trustee, forthwith upon any Officer becoming aware
of any Default or Event of Default, an Officers' Certificate specifying such
Default or Event of Default and what action the Authority is taking or proposes
to take with respect thereto.

Section 4.05.  Taxes.

     The Authority shall pay, and shall cause each of its Subsidiaries to pay,

except such as are contested in good faith and by appropriate proceedings or
where the failure to effect such payment is not adverse in any material respect
to the Holders of the Senior Notes.

Section 4.06.  Stay, Extension and Usury Laws.

     The Authority covenants (to the extent that it may lawfully do so) that it
shall not at any time insist upon, plead, or in any manner whatsoever claim or
take the benefit or advantage of, any stay, extension or usury law wherever
enacted, now or at any time hereafter in force, that may affect the covenants or
the performance of this Indenture; and the Authority (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such
law, and covenants that it shall not, by resort to any such law, hinder, delay
or impede the execution of any power herein granted to the Trustee, but shall
suffer and permit the execution of every such power as though no such law has
been enacted.

Section 4.07.  Restricted Payments.

     (a) The Authority will not, and the Authority will not permit any of its
Restricted Subsidiaries, directly or indirectly, to: (i) make any payment on or

Equity Interests; (ii) purchase, redeem, defease or otherwise acquire or retire
for value any Equity Interest in the Authority held by the Tribe or any

of the Junior Subordinated Notes in accordance with their terms and the terms of
the Defeasance Trust), except a payment of interest or principal at Stated
Maturity thereof; (iv) make any payment or distribution to the Tribe (or any
other agency, instrumentality or political subunit thereof) or make any general
distribution to the members of the Tribe (other than Government Service
Payments); or (v) make any Restricted Investment; (all such payments and other
actions set forth in clauses (i) through (v) are collectively referred to as
"Restricted Payments") unless, at the time of and after giving effect to such
Restricted Payment:

     (A)  no Default or Event of Default shall have occurred and be continuing
          or would occur as a consequence thereof;

     (B)  the Authority would, at the time of such Restricted Payment and after

          $1.00 of additional Indebtedness pursuant to the Fixed Charge Coverage
          Ratio test set forth in Section 4.09(a); and

     (C)  such Restricted Payment, together with the aggregate amount of all
          other Restricted Payments made by the Authority and its Restricted
          Subsidiaries after the date of this Indenture (excluding Restricted
          Payments permitted by clauses (ii), (iii), (iv) and (v) of Section
          4.07(b)), is less than the sum, without duplication, of (1) 50% of the
          Consolidated Net Income of the Authority for the period (taken as one
          accounting period) from the beginning of the first fiscal quarter
          commencing after the date of this Indenture to the end of the
          Authority's most recently ended fiscal quarter for which internal
          financial statements are available at the time of such Restricted
          Payment (or, if such Consolidated Net Income for such period is a
          deficit, less 100% of such deficit), plus (2) 100% of the aggregate
          net cash proceeds or fair market value (as determined in good faith by
          the Management Board and evidenced by a resolution set forth in an
          Officers' Certificate delivered to the Trustee) of assets or property
          (other than cash) received by the Authority from capital contributions
          from the Tribe that bear no mandatory obligation to repay the Tribe
          and other than from a Restricted Subsidiary of the Authority, plus (3)
          to the extent that any Restricted Investment that was made after the
          date of this Indenture is sold, liquidated or otherwise disposed of
          for cash or an amount equal to the fair market value thereof (as
          determined in good faith by the Management Board and evidenced by a
          resolution set forth in an Officers' Certificate delivered to the
          Trustee), the lesser of (I) the cash return of capital or fair market
          value amount, as the case may be, with respect to such Restricted
          Investment (less the cost of disposition, if any) and (II) the initial
          amount of such Restricted Investment, plus (4) to the extent that any
          Unrestricted Subsidiary is redesignated as a Restricted Subsidiary
          after the date of this Indenture, the lesser of (I) the fair market
          value of the Authority's Investment in such Subsidiary as of the date
          of such redesignation or (II) such fair market value as of the date on
          which such Subsidiary was originally designated as an Unrestricted
          Subsidiary.

     (b) So long as no Default has occurred and is continuing or would be caused
thereby, the preceding provisions will not prohibit: (i) the defeasance,
redemption, repurchase or other acquisition of Subordinated Indebtedness with
the net cash proceeds from an incurrence of Permitted Refinancing Indebtedness;
(ii) the payment of any dividend by a Restricted Subsidiary of the Authority to
the holders of its common Equity Interests on a pro rata basis; (iii) the
repurchase, redemption or other acquisition or retirement for value of any
Equity Interests of any Restricted Subsidiary of the Authority held by any
member of the Authority's (or any of its Restricted Subsidiaries') management
pursuant to any management equity subscription agreement or stock option
agreement in effect as of the date of this Indenture; provided that (a) the
aggregate price paid for all such repurchased, redeemed, acquired or retired
Equity Interests shall not exceed $1.0 million in any 12-month period and (b)
the aggregate amount of all such repurchased, redeemed, acquired or retired
Equity Interests shall not in the aggregate exceed $3.0 million; (iv) the
redemption or purchase of Subordinated Indebtedness of the Authority in the
event that the holder of such Subordinated Indebtedness has failed to qualify or
be found suitable or otherwise be eligible by any Gaming Regulatory Authority to
remain a holder of such Subordinated Indebtedness; (v) the redemption,
defeasance, repurchase or other acquisition or retirement of Subordinated
Indebtedness with the net cash proceeds from a substantially concurrent capital
contribution from the Tribe (provided that such capital contribution is not
counted for purposes of Section 4.07(a)(C)(2); and (vi) any other Restricted
Payments in an amount not to exceed $20.0 million at any one time outstanding.


                                       45
                                                                    Senior Notes
<PAGE>
 
     (c) The Authority may designate any Restricted Subsidiary to be an
Unrestricted Subsidiary if such designation would not cause a Default; provided
that in no event shall (i) any entity (including any Subsidiary of the Authority
or the Authority or any operating division thereof) engaged in a Principal
Business be transferred to or held by an Unrestricted Subsidiary or (ii) any Key
Project Assets or Gaming Licenses be transferred to an Unrestricted Subsidiary.
In the event of such designation, all outstanding Investments owned by the
Authority and its Restricted Subsidiaries in the Subsidiary so designated will
be deemed to be an Investment made as of the time of such designation and will
reduce the amount available for Restricted Payments under Section 4.07(a) unless
the Investment constitutes a Permitted Investment. All such outstanding
Investments will be deemed to constitute Restricted Payments in an amount equal
to the fair market value of such Investments at the time of such designation.
Such designation will only be permitted if such Restricted Payment would be
permitted at such time and if such Restricted Subsidiary otherwise meets the
definition of an Unrestricted Subsidiary. The Authority may redesignate an
Unrestricted Subsidiary to be a Restricted Subsidiary if such redesignation
would not otherwise cause a Default.

     (d) The amount of all Restricted Payments (other than cash) shall be the
fair market value on the date of the Restricted Payment of the asset(s) or
securities proposed to be transferred or issued by the Authority or such
Restricted Subsidiary, as the case may be, pursuant to the Restricted Payment.
The fair market value of any assets or securities that are required to be valued
by this Section 4.07 shall be determined by the Management Board whose
resolution with respect thereto shall be delivered to the Trustee. Not later
than the date of making any Restricted Payment, the Authority shall deliver to
the Trustee an Officers' Certificate stating that such Restricted Payment is
permitted and setting forth the basis upon which the calculations required by
this Section 4.07 were computed.

Section 4.08.  Dividend and Other Payment Restrictions Affecting Subsidiaries.

     (a) Except as set forth in Section 4.08(b), the Authority will not, and
will not permit any of its Restricted Subsidiaries to, directly or indirectly,

the ability of any Restricted Subsidiary to: (i) pay dividends or make any other
distributions on its Capital Stock to the Authority or any of the Authority's
Restricted Subsidiaries, or with respect to any other interest or participation
in, or measured by, its profits, or pay any indebtedness owed to the Authority
or any of the Authority's Restricted Subsidiaries; (ii) make loans or advances
to the Authority or any of the Authority's Restricted Subsidiaries; or (iii)
transfer any of its properties or assets to the Authority or any of the
Authority's Restricted Subsidiaries.

     (b) The provisions of Section 4.08(a) will not apply to encumbrances or
restrictions existing under or by reason of:

       (i)    Existing Indebtedness as in effect on the date of this Indenture
              and any amendments, modifications, restatements, renewals,
              extensions, increases, supplements, refundings, replacements or
              refinancings thereof, provided that such amendments,
              modifications, restatements, renewals, extensions, increases,
              supplements, refundings, replacements or refinancings are no more
              restrictive, taken as a whole, with respect to such dividend and
              other payment restrictions than those contained in such Existing
              Indebtedness, as in effect on the date of this Indenture;

       (ii)   this Indenture and the Senior Notes;

       (iii)  the Senior Subordinated Notes Indenture and the Senior
              Subordinated Notes;

              such Indebtedness was incurred in connection with or in
              contemplation of such acquisition), which encumbrance or
              restriction is not applicable to any Person, or the properties or
              assets of any Person, other than the Person, or the property or
              assets of the Person, so acquired, provided that, in the case of
              Indebtedness, such Indebtedness was permitted by the terms of this
              Indenture to be incurred;

       (vii)  customary non-assignment provisions in leases or other contracts
              entered into in the ordinary course of business and consistent
              with past practices;

       (viii) purchase money obligations (including, without limitation, Capital
              Lease Obligations) for property acquired in the ordinary course of
              business that impose restrictions on the property so acquired of
              the nature described in clause (iii) of Section 4.08(a);

       (ix)   any agreement for the sale or other disposition of a Restricted
              Subsidiary that restricts distributions by such Restricted
              Subsidiary pending its sale or other disposition;

       (x)    Permitted Refinancing Indebtedness, provided that the restrictions
              contained in the agreements governing such Permitted Refinancing
              Indebtedness are no more restrictive, taken as a whole, than those
              contained in the agreements governing the Indebtedness being
              refinanced;

       (xi)   Liens securing Indebtedness otherwise permitted to be incurred
              pursuant to Section 4.12 that limit the right of the Authority or
              any of its Restricted Subsidiaries to dispose of the assets
              subject to such Lien;

       (xii)  provisions with respect to the disposition or distribution of
              assets or property in joint venture agreements and other similar
              agreements entered into in the ordinary course of business; and

       (xiii) restrictions on cash or other deposits or net worth imposed by
              customers under contracts entered into in the ordinary course of
              business.

Section 4.09.  Incurrence of Indebtedness and Issuance of Preferred Stock.

     (a) The Authority will not, and will not permit any of its Subsidiaries to,
directly or indirectly, create, incur, issue, assume, guarantee or otherwise
become directly or indirectly liable, contingently or otherwise, with respect to
(collectively, "incur") any Indebtedness (including Acquired Indebtedness) and
the Authority will not issue any Disqualified Stock and will not permit any of
its Subsidiaries to issue any shares of preferred stock; provided, however, that
the Authority may incur Indebtedness (including Acquired Indebtedness) or issue
shares of Disqualified Stock and the Authority's Subsidiaries may incur
Indebtedness or issue preferred stock if the Fixed Charge Coverage Ratio for the
Authority's most recently ended four full fiscal quarters for which internal
financial statements are available immediately preceding the date on which such
additional Indebtedness is incurred would have been at least 2.0 to 1 if such
Indebtedness is incurred prior to September 30, 2001 


                                       47
                                                                    Senior Notes
<PAGE>
 
and 2.5 to 1 if such indebtedness is incurred thereafter, determined on a pro
forma basis (including a pro forma application of the net proceeds therefrom),
as if the additional Indebtedness had been incurred at the beginning of such
four-quarter period. Notwithstanding the foregoing, the Authority will not issue
any Disqualified Stock or any type of Capital Stock that would violate IGRA.

     (b) So long as no Default or Event of Default shall have occurred and be
continuing, or would be caused thereby, Section 4.09(a) will not prohibit the
incurrence of any of the following items of Indebtedness:

       (i)    the incurrence by the Authority or its Restricted Subsidiaries of
              Indebtedness and letters of credit pursuant to Credit Facilities;
              provided that the aggregate principal amount of all such
              Indebtedness and letters of credit outstanding under all Credit
              Facilities, after giving effect to such incurrence (with letters
              of credit being deemed to have a principal amount equal to the
              maximum potential liability of the Authority thereunder), does not
              exceed $500.0 million less the aggregate amount of all Net
              Proceeds of Asset Sales applied by the Authority or any of its
              Restricted Subsidiaries since the date of this Indenture to repay
              Indebtedness under Credit Facilities permitted under Section 4.10;

       (ii)   the incurrence by the Authority and its Restricted Subsidiaries of
              the Existing Indebtedness;

       (iii)  the incurrence by the Authority of Indebtedness represented by the
              Senior Notes and the Senior Exchange Notes;

       (iv)   the incurrence by the Authority of Indebtedness represented by the
              Senior Subordinated Notes and the Senior Subordinated Exchange
              Notes;

       (v)    the incurrence by the Authority or any of its Restricted
              Subsidiaries of Indebtedness represented by Capital Lease
              Obligations, mortgage financings or purchase money obligations, in
              each case incurred for the purpose of financing all or any part of
              the purchase price of furniture, fixtures, equipment or similar
              assets used or useful in the business of the Authority or such
              Restricted Subsidiary not to exceed 100% of the lesser of cost or
              fair market value of the assets financed and, in an aggregate
              principal amount under this clause (v) not to exceed $25.0 million
              at any time outstanding;

       (vi)   the incurrence by the Authority or any of its Restricted
              Subsidiaries of Permitted Refinancing Indebtedness in exchange
              for, or the net proceeds of which are used to refund, refinance,
              renew, extend, defease or replace Indebtedness that was permitted
              by this Indenture to be incurred under Section 4.09(a) or clauses
              (i), (ii) (other than the Junior Subordinated Notes), (iii), (iv)
              or (v) of this Section 4.09(b);

       (vii)  the incurrence by the Authority or any of its Restricted
              Subsidiaries of Hedging Obligations that are incurred for the
              purpose of fixing or hedging interest rate risk with respect to
              any floating rate Indebtedness that is permitted by the terms of
              this Indenture to be outstanding;

       (viii) the guarantee by the Authority or any of its Restricted
              Subsidiaries of any Indebtedness of the Authority or any of its
              Restricted Subsidiaries that was permitted to be incurred by
              another provision of this Section 4.09;


                                       48
                                                                    Senior Notes
<PAGE>
 
       (ix)   the incurrence by a Wholly Owned Restricted Subsidiary of
              Indebtedness owed to another Wholly Owned Restricted Subsidiary or
              to the Authority; provided that if at any time any such Wholly
              Owned Restricted Subsidiary ceases to be a Wholly Owned Restricted
              Subsidiary, any such Indebtedness shall be deemed to be an
              incurrence of Indebtedness for the purposes of this Section 4.09;

       (x)    the incurrence by the Authority or any of its Restricted
              Subsidiaries of additional Indebtedness in an aggregate principal
              amount (or accreted value, as applicable) at any time outstanding,
              including all Permitted Refinancing Indebtedness incurred to
              refund, refinance or replace any Indebtedness incurred pursuant to
              this clause (x), not to exceed $25.0 million; or

       (xi)   the incurrence by the Authority's Unrestricted Subsidiaries of
              Non-Recourse Debt, provided, however, that if any such
              Indebtedness ceases to be Non-Recourse Debt of an Unrestricted
              Subsidiary, such event shall be deemed to constitute an incurrence
              of Indebtedness by a Restricted Subsidiary of the Authority that
              was not permitted by this clause (xi).

     For purposes of determining compliance with this Section 4.09 in the event
that an item of proposed Indebtedness meets the criteria of more than one of the
categories of Indebtedness described in clauses (i) through (xi) above or is
entitled to be incurred pursuant to Section 4.09(a), the Authority shall, in its
sole discretion, classify such item of Indebtedness on the date of its
incurrence in any manner that complies with this Section 4.09.

Section 4.10.  Asset Sales.

     (a) The Authority will not, and will not permit any of its Restricted
Subsidiaries to, consummate an Asset Sale unless: (i) the Authority (or its
Restricted Subsidiary, as the case may be) receives consideration at the time of
such Asset Sale at least equal to the fair market value (as determined in good
faith by the Management Board and evidenced by a resolution set forth in an
Officers' Certificate delivered to the Trustee) of the assets sold or otherwise
disposed of; and (ii) except in the case of a Permitted Asset Swap, at least 75%
of the consideration therefor received by the Authority or such Restricted
Subsidiary is in the form of cash. For purposes of this provision, each of the
following shall be deemed to be cash: (A) any liabilities that would appear on
the Authority's or such Restricted Subsidiary's balance sheet prepared in
accordance with GAAP (other than contingent liabilities and liabilities that are
by their terms subordinated to the Senior Notes or any guarantee thereof) that
are assumed by the transferee of any such assets pursuant to a customary
novation agreement that releases the Authority or such Restricted Subsidiary
from further liability; and (B) any securities, notes or other obligations
received by the Authority or any such Restricted Subsidiary from such transferee
that are converted by the Authority or such Restricted Subsidiary into cash (to
the extent of the cash received) within 30 days of the receipt thereof,
provided, however, that the Authority will not be permitted to make any Asset
Sale of Key Project Assets.

     (b) Within 360 days after the receipt of any Net Proceeds from an Asset
Sale, the Authority may apply such Net Proceeds, at its option, to: (i) repay
permanently term Indebtedness under Credit Facilities of the Authority or any
Restricted Subsidiary; (ii) repay revolving credit Indebtedness under Credit
Facilities and correspondingly permanently reduce commitments with respect
thereto; (iii) acquire a majority of the assets of, or a majority of the Voting
Stock of, an entity engaged in the Principal Business or a Related Business;
(iv) make capital expenditures or acquire other long-term assets that are used
or useful in the Principal Business or a Related Business; (v) make an
investment in the Principal 


                                       49
                                                                    Senior Notes
<PAGE>
 
Business or a Related Business or in tangible long-term assets used or useful in
the Principal Business or a Related Business; or (vi) reduce permanently
Indebtedness that is not Subordinated Indebtedness.

     Pending the final application of any such Net Proceeds, the Authority may
temporarily reduce revolving credit borrowings or otherwise invest such Net
Proceeds in any manner that is not prohibited by this Indenture.

     (c) Any Net Proceeds from Asset Sales that are not applied or invested as
provided in Section 4.10(b) will be deemed to constitute "Excess Proceeds." When
the aggregate amount of Excess Proceeds exceeds $15.0 million, the Authority
will make an Asset Sale Offer to all Holders of Senior Notes and all holders of
other Indebtedness containing provisions similar to those set forth in this
Indenture with respect to offers to purchase or redeem with the proceeds of
sales of assets to purchase the maximum principal amount of Senior Notes and
such other Indebtedness that may be purchased out of the Excess Proceeds. The
offer price in any Asset Sale Offer will be equal to 100% of the principal
amount plus accrued and unpaid interest and Additional Interest, if any, to the
date of purchase and will be payable in cash, in accordance with the procedures
set forth in this Indenture and such other Indebtedness. To the extent that any
Excess Proceeds remain after consummation of an Asset Sale Offer, the Authority
may use such Excess Proceeds for any purpose not otherwise prohibited by this
Indenture. If the aggregate principal amount of Senior Notes and such other
Indebtedness tendered into such Asset Sale Offer surrendered by holders thereof
exceeds the amount of Excess Proceeds, the Trustee shall select the Senior Notes
and such other Indebtedness (to the extent that such other Indebtedness permits
such selection) to be purchased on a pro rata basis. Upon completion of such
offer to purchase, the amount of Excess Proceeds shall be reset at zero.

Section 4.11.  Transactions with Affiliates.

     (a) The Authority will not, and the Authority will not permit any of its
Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or
otherwise dispose of any of its properties or assets to, or purchase any
property or assets from, or enter into or make or amend any transaction,
contract, agreement, understanding, loan, advance or guarantee with, or for the
benefit of, any Affiliate (each of the foregoing, an "Affiliate Transaction"),
unless: (i) such Affiliate Transaction is on terms that are no less favorable to
the Authority or the relevant Restricted Subsidiary than those that would have
been obtained in a comparable transaction by the Authority or such Restricted
Subsidiary with an unrelated Person; and (ii) the Authority delivers to the
Trustee: (A) with respect to any Affiliate Transaction or series of related
Affiliate Transactions involving aggregate consideration in excess of $5.0
million, a resolution of the Management Board set forth in an Officers'
Certificate certifying that such Affiliate Transaction complies with this
Section 4.11 and that such Affiliate Transaction has been approved by a majority
of the disinterested members of the Management Board; and (B) with respect to
any Affiliate Transaction or series of related Affiliate Transactions involving
aggregate consideration in excess of $10.0 million, an opinion as to the
fairness to the Authority or such Restricted Subsidiary of such Affiliate
Transaction from a financial point of view issued by an accounting, appraisal or
investment banking firm of national standing.

     (b) The following items shall not be deemed to be Affiliate Transactions
and, therefore, will not be subject to the provisions of Section 4.11(a): (i)
any employment agreement or arrangement entered into by the Authority or any of
its Restricted Subsidiaries in the ordinary course of business and consistent
with the past practice of the Authority or such Restricted Subsidiary; (ii)
transactions between or among the Authority and/or its Restricted Subsidiaries;
(iii) payment of reasonable Management Board fees to members of the Management
Board; (iv) transactions with Persons in whom the Authority owns any Equity
Interests, so long as the remaining equity holders of such Person are not
Affiliates 


                                       50
                                                                    Senior Notes
<PAGE>
 
of the Authority or any of its Subsidiaries; (v) Government Service Payments;
(vi) transactions pursuant to the Development Services Agreement, the
Relinquishment Agreement and the Side Letters; (vii) Restricted Payments or
Permitted Investments that are made in compliance with the provisions of Section
4.07; and (viii) contractual arrangements existing on the date of this Indenture
and renewals, extensions and any modifications thereof that are not materially
adverse to Holders.

Section 4.12.  Liens.

     The Authority will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, create, incur, assume or otherwise
cause or suffer to exist or become effective any Lien of any kind (other than
Permitted Liens) upon any of its property or assets, now owned or hereafter
acquired, unless all payments due under this Indenture and the Senior Notes are
secured on an equal and ratable basis with the obligations so secured until such
time as such obligations are no longer secured by a Lien.

Section 4.13.  Line of Business.

     The Authority shall not, and shall not permit any of its Restricted
Subsidiaries to, engage in any business other than the Principal Business or a
Related Business.

Section 4.14.  Existence of the Authority and Maintenance of the Lease.

     (a) The Authority shall, and shall cause each of its Restricted
Subsidiaries to, do or cause to be done all things necessary to preserve and
keep in full force and effect their respective existence, in accordance with
their respective organizational documents and their respective rights
(contractual, charter and statutory), licenses and franchises; provided,
however, that neither the Authority nor any Restricted Subsidiary shall be
required to preserve, with respect to itself, any license, right or franchise
and, with respect to its Restricted Subsidiaries, any such existence, license,
right or franchise, if its Management Board or Board of Directors, or other
governing body or officers authorized to make such determination, as the case
may be, shall determine that the preservation thereof is no longer desirable in
the conduct of the business of the Authority or any Restricted Subsidiary, and
that the loss thereof is not adverse in any material respect to the Holders.

     (b) The Authority shall do, or cause to be done, all things necessary to
perform any material covenants set forth in the Lease in order to keep the Lease
in full force and effect.

Section 4.15.  Offer to Repurchase Upon Change of Control.

     (a) If a Change of Control occurs, each Holder of the Senior Notes will
have the right to require the Authority to repurchase all or any part (equal to
$1,000 or an integral multiple thereof) of that Holder's Senior Notes pursuant
to a Change of Control Offer. In the Change of Control Offer, the Authority will
offer a Change of Control Payment in cash equal to 101% of the aggregate
principal amount of Senior Notes repurchased plus accrued and unpaid interest
and Additional Interest, if any, thereon, to the date of purchase.

     (b) Within 20 Business Days following any Change of Control, the Authority
will mail a notice to each Holder describing the transaction or transactions
that constitute the Change of Control and offering to repurchase Senior Notes on
the Change of Control Payment Date specified in such notice, pursuant to the
procedures required by this Indenture and described in such notice. The
Authority will comply with the requirements of Rule 14e-1 under the Exchange Act
and any other securities laws and 


                                       51
                                                                    Senior Notes
<PAGE>
 
regulations thereunder to the extent such laws and regulations are applicable in
connection with the repurchase of the Senior Notes as a result of a Change of
Control.

     (c) On the Change of Control Payment Date, the Authority will, to the
extent lawful: (i) accept for payment all Senior Notes or portions thereof
properly tendered pursuant to the Change of Control Offer; (ii) deposit with the
Paying Agent an amount equal to the Change of Control Payment in respect of all
Senior Notes or portions thereof so tendered; and (iii) deliver or cause to be
delivered to the Trustee the Senior Notes so accepted together with an Officers'
Certificate stating the aggregate principal amount of Senior Notes or portions
thereof being purchased by the Authority.

     (d) The Paying Agent will promptly mail to each Holder of Senior Notes so
tendered the Change of Control Payment for such Senior Notes, and the Trustee
will promptly authenticate and mail (or cause to be transferred by book entry)
to each Holder a new Senior Note equal in principal amount to any unpurchased
portion of the Senior Notes surrendered, if any; provided that each such new
Senior Note will be in a principal amount of $1,000 or an integral multiple
thereof. The Authority will notify the Trustee and will instruct the Trustee to
notify the Holders of the results of the Change of Control Offer on or as soon
as practicable after the Change of Control Payment Date.

     (e) Notwithstanding anything to the contrary in this Section 4.15, the
Authority shall not be required to make a Change of Control Offer upon a Change
of Control if a third party makes the Change of Control Offer in the manner, at
the times and otherwise in compliance with the requirements set forth in this
Section 4.15 and Section 3.10 hereof and all other provisions of this Indenture
applicable to a Change of Control Offer made by the Authority and purchases all
Senior Notes validly tendered and not withdrawn under such Change of Control
Offer.

Section 4.16.  Limitation on Sale and Leaseback Transactions.

     The Authority will not, and will not permit any of its Restricted
Subsidiaries to, enter into any sale and leaseback transaction involving the
Resort; provided that the Authority or any of its Restricted Subsidiaries may
enter into a sale and leaseback transaction if: (i) the Authority or such
Restricted Subsidiary, as applicable, could have (a) incurred Indebtedness in an
amount equal to the Attributable Debt relating to such sale and leaseback
transaction pursuant to the Fixed Charge Coverage Ratio test set forth in
Section 4.09(a) and (b) incurred a Lien to secure such Indebtedness pursuant to
Section 4.12; (ii) the gross cash proceeds of such sale and leaseback
transaction are at least equal to the fair market value, as determined in good
faith by the Management Board and set forth in an Officers' Certificate
delivered to the Trustee, of the property that is subject of such sale and
leaseback transaction; and (iii) the transfer of assets in such sale and
leaseback transaction is permitted by, and the Authority applies the proceeds of
such transaction in compliance with Section 4.10; provided that, upon the
occurrence of a Rating Event Date and for so long as the covenants set forth in
Section 4.26 continue to be Suspended Provisions, the following provisions shall
replace the foregoing provisions with respect to sale and leaseback transactions
by the Authority and its Restricted Subsidiaries: The Authority will not, and
will not permit any of its Restricted Subsidiaries to, enter into any sale and
leaseback transaction involving the Resort; provided that the Authority or any
Restricted Subsidiary may enter into any sale and leaseback transaction with an
Attributable Value (when taken together with all other sale and leaseback
transactions of the Authority and its Restricted Subsidiaries) that, at the time
of such transaction, after giving effect thereto, does not exceed 10% of
Consolidated Net Tangible Assets.

                                                                    Senior Notes

               Owned Restricted Subsidiaries.

     The Authority (i) will not, and will not permit any Wholly Owned Restricted
Subsidiary of the Authority to, transfer, convey, sell, lease or otherwise
dispose of any Equity Interests in any Wholly Owned Restricted Subsidiary of the
Authority to any Person (other than the Authority or another Wholly Owned
Restricted Subsidiary of the Authority), unless (a) such transfer, conveyance,
sale, lease or other disposition is of all the Equity Interests in such Wholly
Owned Restricted Subsidiary and (b) the cash Net Proceeds from such transfer,
conveyance, sale, lease or other disposition are applied in accordance with
Section 4.10, and (ii) will not permit any Wholly Owned Restricted Subsidiary of
the Authority to issue any of its Equity Interests (other than, if necessary,
shares of its Capital Stock constituting directors' qualifying shares) to any
Person other than to the Authority or a Wholly Owned Restricted Subsidiary of
the Authority.

Section 4.18.  Limitation on Issuances of Senior Guarantees of Indebtedness.

     The Authority shall not permit any Subsidiary, directly or indirectly, to
guarantee or pledge any assets to secure the payment of any other Indebtedness
of the Authority unless such Subsidiary simultaneously executes and delivers a
supplemental indenture to this Indenture providing for the guarantee of the
payment of the Senior Notes by such Subsidiary, which Senior Subsidiary
Guarantee shall be senior to or pari passu with such Subsidiary's guarantee of
or pledge to secure such other Indebtedness. Notwithstanding the foregoing, any
such Senior Subsidiary Guarantee by a Subsidiary of the Senior Notes shall
provide by its terms that it shall be automatically and unconditionally released
and discharged upon any sale, exchange or transfer, to any Person not an
Affiliate of the Authority, of all of the Authority's stock in, or all or
substantially all the assets of, such Subsidiary, which sale, exchange or
transfer is made in compliance with the applicable provisions of this Indenture.
The form of such Senior Subsidiary Guarantee is attached as Exhibit D hereto.

Section 4.19.  Payments for Consent.

     Neither the Authority nor any of its Restricted Subsidiaries shall,

way of interest, fee or otherwise, to any Holder of any Senior Notes for or as
an inducement to any consent, waiver or amendment of any of the terms or
provisions of this Indenture or the Senior Notes unless such consideration is
offered to be paid or is paid to all Holders of the Senior Notes that consent,
waive or agree to amend in the time frame set forth in the solicitation
documents relating to such consent, waiver or agreement.

Section 4.20.  Senior Subsidiary Guarantees.

     If the Authority shall acquire or create a Restricted Subsidiary after the
date of this Indenture, then such newly acquired or created Restricted
Subsidiary shall execute a Senior Subsidiary Guarantee in the form of a
Supplemental Indenture and deliver an Opinion of Counsel, in accordance with the
terms of this Indenture, except for (i) all Subsidiaries organized outside of
the United States and its territories and (ii) all Subsidiaries that have
properly been designated as Unrestricted Subsidiaries in accordance with this

     (a) Except as provided in Section 4.24(b), the Authority will not lease,
sublease, or grant a license, concession or other agreement to occupy, manage or
use any material portion of the Authority's property and assets owned or leased
by the Authority (each, a "Lease Transaction").

     (b) Section 4.24(a) will not prohibit any of the following Lease
Transactions:

       (i)    The Authority may enter into a Lease Transaction with respect to
              any space with any Person (including, without limitation, a lease
              in connection with the Expansion Project for the purpose of

     Customary insurance coverage shall be deemed to include the following:

     (a)  workers' compensation insurance to the extent required to comply with
          all applicable state, territorial, or United States laws and
          regulations, or the laws and regulations of any other applicable

          earthquake, civil commotion, malicious mischief, hurricane, and such
          other risks and hazards as are from time to time covered by an
          "all-risk" policy or a property policy covering "special" causes of
          loss (such insurance shall provide coverage of not less than 100% of
          actual replacement value (as determined at each policy renewal based
          on the F.W. Dodge Building Index or some other recognized means) of
          any improvements and with a deductible no greater than $500,000 (other
          than earthquake insurance, for which the deductible may be up to 10%
          of such replacement value)).

Section 4.26.  Changes in Covenants when Senior Notes Rated Investment Grade.

     Following the first date upon which the Senior Notes are rated Baa3 or
better by Moody's and BBB- or better by S&P (or, in either case, if such person
ceases to rate the Senior Notes for reasons outside of the control of the
Authority, the equivalent investment grade credit rating from any other
"nationally recognized statistical rating organization" (within the meaning of
Rule 15c3-1(c)(2)(vi)(F) under the Exchange Act) selected by the Authority as a
replacement agency) (the "Rating Event Date") and provided no Event of Default
or event that with notice or the passage of time would constitute an Event of
Default shall exist on the Rating Event Date, Sections 4.07, 4.08, 4.09, 4.10,
4.11, 4.17, 4.23, 4.24 and 4.25 in this Indenture (collectively, the "Suspended
Provisions") will no longer be applicable to the Senior Notes; provided,
however, that in the event that at any time after a Rating Event Date, the
Senior Notes shall be rated lower than Baa3 by Moody's or lower than BBB- by
S&P, or any equivalent rating by a successor agency to Moody's or S&P, the
Suspended Sections shall be automatically reinstated (the "Reinstated
Provisions") and all transactions by the Authority that occurred during the time
that such sections were suspended and that would have violated such sections had
such sections been in effect at the time shall be deemed not to constitute a
Default or an Event of Default, as the case may be, and shall be deemed to have
been in compliance with such sections for all purposes; provided 


                                       55
                                                                    Senior Notes
<PAGE>
 
further that thereafter all transactions by the Authority occurring on or after
the date on which the Suspended Provisions have been reinstated shall be
required to be in compliance with the Reinstated Provisions. For purposes of
interpreting the definition of "Permitted Liens" during the time any such
Sections are suspended, the definition should be read as if the Sections were
not so suspended.

Section 4.27.  Gaming Licenses

     The Authority will use its best efforts to obtain and retain in full force
and effect at all times all Gaming Licenses necessary for the operation of the
Resort, provided, that, if in the course of the exercise of its governmental or
regulatory functions the Authority is required to suspend or revoke any consent,
permit or license or close or suspend any operation or any part of the Resort as
a result of any noncompliance with the law, the Authority will use its best
efforts to promptly and diligently correct such noncompliance or replace any
personnel causing such noncompliance so that the Resort will be opened and fully
operating.

     The Authority shall file with the Trustee and provide Holders of Senior
Notes any Notice of Violation, Order of Temporary Closure, or Assessment of
Civil Fines from the NIGC pursuant to 25 C.F.R. Part 573 or 575 or any successor
provision, and any notice of Non-Compliance issued by, or cause of action
commenced by, the State of Connecticut under Section 13 of the Compact, or any
successor provision.

               Notes.

Defeasance Trust and deposit into the Defeasance Trust cash or government
securities estimated to be sufficient to pay all principal, premium and interest
on the Junior Subordinated Notes less $500,000 on January 1, 2000, the first
redemption date. The Authority will redeem the Junior Subordinated Notes from
the proceeds of the Defeasance Trust as of January 1, 2000 at a price of 100% of
the principal amount, plus accrued and unpaid interest thereon, less $500,000.

Section 4.29.  Designation of Designated Senior Indebtedness Under the 
               Relinquished Agreement.

     The Authority will not designate any indebtedness as "Designated Senior
Indebtedness" under the Relinquishment Agreement that is not also designated as
Designated Senior Indebtedness under the Senior Subordinated Notes Indenture.

          Authority or any of its Restricted Subsidiaries) whether such
          Indebtedness or guarantee now exists, or is created after the date of

          Senior Notes then outstanding voting as a single class.

Section 6.02.  Acceleration.

     If any Event of Default (other than an Event of Default specified in clause
(g) or (h) of Section 6.01 hereof with respect to the Authority, any Restricted
Subsidiary that is a Significant Subsidiary or any group of Restricted
Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary)
occurs and is continuing, the Trustee or the Holders of at least 25% in
principal amount of the then outstanding Senior Notes may declare all the Senior
Notes to be due and payable immediately. Upon any such declaration, the Senior
Notes shall become due and payable immediately. Notwithstanding the foregoing,
if an Event of Default specified in clause (g) or (h) of Section 6.01 hereof
occurs with respect to the Authority, any of its Restricted Subsidiaries that
are Significant Subsidiaries or any group of Restricted Subsidiaries that, taken
as a whole, would constitute a Significant Subsidiary, all outstanding 


                                       58
                                                                    Senior Notes
<PAGE>
 
Senior Notes shall be due and payable immediately without further action or
notice. The Holders of a majority in aggregate principal amount of the then
outstanding Senior Notes by written notice to the Trustee may on behalf of all
of the Holders rescind an acceleration and its consequences if the rescission
would not conflict with any judgment or decree and if all existing Events of
Default (except nonpayment of principal, interest or premium that has become due
solely because of the acceleration) have been cured or waived.

Section 6.03.  Other Remedies.

     If an Event of Default occurs and is continuing, the Trustee may pursue any
available remedy to collect the payment of principal, premium, if any, and
interest on the Senior Notes or to enforce the performance of any provision of
the Senior Notes or this Indenture.

     The Trustee may maintain a proceeding even if it does not possess any of
the Senior Notes or does not produce any of them in the proceeding. A delay or
omission by the Trustee or any Holder of a Senior Note in exercising any right
or remedy accruing upon an Event of Default shall not impair the right or remedy
or constitute a waiver of or acquiescence in the Event of Default. All remedies
are cumulative to the extent permitted by law.

Section 6.04.  Waiver of Past Defaults.

     Holders of not less than a majority in aggregate principal amount of the
then outstanding Senior Notes by notice to the Trustee may on behalf of the
Holders of all of the Senior Notes waive an existing Default or Event of Default
and its consequences hereunder, except a continuing Default or Event of Default
in the payment of the principal of, premium and Additional Interest , if any, or
interest on, the Senior Notes (including in connection with an offer to
purchase) (provided, however, that the Holders of a majority in aggregate
principal amount of the then outstanding Senior Notes may rescind an
acceleration and its consequences, including any related payment default that
resulted from such acceleration). Upon any such waiver, such Default shall cease
to exist, and any Event of Default arising therefrom shall be deemed to have
been cured for every purpose of this Indenture; but no such waiver shall extend
to any subsequent or other Default or impair any right consequent thereon.

Section 6.05.  Control by Majority.

     Holders of a majority in principal amount of the then outstanding Senior
Notes may direct the time, method and place of conducting any proceeding for
exercising any remedy available to the Trustee or exercising any trust or power
conferred on it. However, the Trustee may refuse to follow any direction that
conflicts with law or this Indenture that the Trustee determines may be unduly
prejudicial to the rights of other Holders of Senior Notes or that may involve
the Trustee in personal liability.

Section 6.06.  Limitation on Suits.

     A Holder of a Senior Note may pursue a remedy with respect to this
Indenture or the Senior Notes only if:

     (a) the Holder of a Senior Note gives to the Trustee written notice of a
continuing Event of Default;

     (b) the Holders of at least 25% in principal amount of the then outstanding
Senior Notes make a written request to the Trustee to pursue the remedy;


                                       59
                                                                    Senior Notes
<PAGE>
 
     (c) such Holder of a Senior Note or Holders of Senior Notes offer and, if
requested, provide to the Trustee indemnity satisfactory to the Trustee against
any loss, liability or expense;

     (d) the Trustee does not comply with the request within 60 days after
receipt of the request and the offer and, if requested, the provision of
indemnity; and

     (e) during such 60-day period the Holders of a majority in principal amount
of the then outstanding Senior Notes do not give the Trustee a direction
inconsistent with the request.

     A Holder of a Senior Note may not use this Indenture to prejudice the
rights of another Holder of a Senior Note or to obtain a preference or priority
over another Holder of a Senior Note.

Section 6.07.  Rights of Holders of Senior Notes to Receive Payment.

     Notwithstanding any other provision of this Indenture, the right of any
Holder of a Senior Note to receive payment of principal, premium and Additional
Interest, if any, and interest on the Senior Note, on or after the respective
due dates expressed in the Senior Note (including in connection with an offer to
purchase), or to bring suit for the enforcement of any such payment on or after
such respective dates, shall not be impaired or affected without the consent of
such Holder.

Section 6.08.  Collection Suit by Trustee.

     If an Event of Default specified in Section 6.01(a) or (b) occurs and is
continuing, the Trustee is authorized to recover judgment in its own name and as
trustee of an express trust against the Authority for the whole amount of
principal of, premium and Additional Interest, if any, and interest remaining
unpaid on the Senior Notes and interest on overdue principal and, to the extent
lawful, interest and such further amount as shall be sufficient to cover the
costs and expenses of collection, including the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel.

Section 6.09.  Trustee May File Proofs of Claim.

     The Trustee is authorized to file such proofs of claim and other papers or
documents as may be necessary or advisable in order to have the claims of the
Trustee (including any claim for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel) and the
Holders of the Senior Notes allowed in any judicial proceedings relative to the
Authority (or any other obligor upon the Senior Notes), its creditors or its
property and shall be entitled and empowered to collect, receive and distribute
any money or other property payable or deliverable on any such claims and any
custodian in any such judicial proceeding is hereby authorized by each Holder to
make such payments to the Trustee, and in the event that the Trustee shall
consent to the making of such payments directly to the Holders, to pay to the
Trustee any amount due to it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 7.07 hereof. To the extent that the
payment of any such compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 7.07 hereof out of the estate in any such proceeding, shall be denied
for any reason, payment of the same shall be secured by a Lien on, and shall be
paid out of, any and all distributions, dividends, money, securities and other
properties that the Holders may be entitled to receive in such proceeding
whether in liquidation or under any plan of reorganization or arrangement or
otherwise. Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or 


                                       60
                                                                    Senior Notes

composition affecting the Senior Notes or the rights of any Holder, or to
authorize the Trustee to vote in respect of the claim of any Holder in any such
proceeding.

Section 6.10.  Priorities.

     If the Trustee collects any money pursuant to this Article, it shall pay
out the money in the following order:

          First:  to the Trustee, its agents and attorneys for amounts due under
     Section 7.07 hereof, including payment of all compensation, expense and
     liabilities incurred, and all advances made, by the Trustee and the costs
     and expenses of collection;

          Second: to Holders of Senior Notes for amounts due and unpaid on the
     Senior Notes for principal, premium and Additional Interest, if any, and
     interest, ratably, without preference or priority of any kind, according to
     the amounts due and payable on the Senior Notes for principal, premium and
     Additional Interest, if any, and interest, respectively; and

          Third:  to the Authority or to such party as a court of competent
     jurisdiction shall direct.

     The Trustee may fix a record date and payment date for any payment to
Holders of Senior Notes pursuant to this Section 6.10.

Section 6.11.  Undertaking for Costs.

     In any suit for the enforcement of any right or remedy under this Indenture
or in any suit against the Trustee for any action taken or omitted by it as a
Trustee, a court in its discretion may require the filing by any party litigant
in the suit of an undertaking to pay the costs of the suit, and the court in its
discretion may assess reasonable costs, including reasonable attorneys' fees,
against any party litigant in the suit, having due regard to the merits and good
faith of the claims or defenses made by the party litigant. This Section does
not apply to a suit by the Trustee, a suit by a Holder of a Senior Note pursuant
to Section 6.07 hereof, or a suit by Holders of more than 10% in principal
amount of the then outstanding Senior Notes.

Section 7.01.  Duties of Trustee.

     (a) If an Event of Default has occurred and is continuing, the Trustee
shall exercise such of the rights and powers vested in it by this Indenture, and
use the same degree of care and skill in its exercise, as a prudent person would
exercise or use under the circumstances in the conduct of such person's own
affairs.

     (b) Except during the continuance of an Event of Default:

     (i)  the duties of the Trustee shall be determined solely by the express
          provisions of this Indenture and the Trustee need perform only those
          duties that are specifically set forth in this Indenture and no
          others, and no implied covenants or obligations shall be read into

          opinions expressed therein, upon certificates or opinions furnished to
          the Trustee and conforming to the requirements of this Indenture.
          However, the Trustee shall examine the certificates and opinions to
          determine whether or not they conform to the requirements of this
          Indenture.

          Section 7.01;

     (ii) the Trustee shall not be liable for any error of judgment made in good
          faith by a Responsible Officer, unless it is proved that the Trustee
          was negligent in ascertaining the pertinent facts; and

     (iii) the Trustee shall not be liable with respect to any action it takes
          or omits to take in good faith in accordance with a direction received
          by it pursuant to Section 6.05 hereof.

     (a) The Trustee may conclusively rely upon any document believed by it to
be genuine and to have been signed or presented by the proper Person. The
Trustee need not investigate any fact or matter stated in the document.

     (b) Before the Trustee acts or refrains from acting, it may require an
Officers' Certificate or an Opinion of Counsel or both. The Trustee shall not be
liable for any action it takes or omits to take in good faith in reliance on
such Officers' Certificate or Opinion of Counsel. The Trustee may consult with
counsel and the written advice of such counsel or any Opinion of Counsel shall
be full and complete authorization and protection from liability in respect of
any action taken, suffered or omitted by it hereunder in good faith and in
reliance thereon.

request, direction or notice from the Authority shall be sufficient if signed by
an Officer of the Authority.

Section 7.03.  Individual Rights of Trustee.

     The Trustee in its individual or any other capacity may become the owner or

     Within 60 days after each May 15 beginning with the May 15 following the
date of this Indenture, and for so long as Senior Notes remain outstanding, the

TIA ss. 313(c).

                                       63
                                                                    Senior Notes
<PAGE>
 
     At the express direction of the Authority and at the Authority's expense,
the Trustee will provide any Gaming Regulatory Authority with:

       (i)    copies of all notices, reports and other written communications
              which the Trustee gives to Holders;

       (ii)   a list of all of the Holders promptly after the original issuance
              of the Senior Notes and periodically thereafter if the Authority

              the Indebtedness evidenced hereby, the institution of any legal
              actions or proceedings before any court or governmental authority
              in respect of a Default or Event of Default hereunder.;

              within five Business Days of the effectiveness thereof.

     To the extent requested by the Authority and at the Authority's expense,
the Trustee shall cooperate with any Gaming Regulatory Authority in order to
provide such Gaming Regulatory Authority with the information and documentation
requested and as otherwise required by applicable law.

Section 7.07.  Compensation and Indemnity.

     The Authority shall pay to the Trustee from time to time reasonable
compensation for its acceptance of this Indenture and services hereunder. The
Trustee's compensation shall not be limited by any law on compensation of a
trustee of an express trust. The Authority shall reimburse the Trustee promptly
upon request for all reasonable disbursements, advances and expenses incurred or
made by it in addition to the compensation for its services. Such expenses shall
include the reasonable compensation, disbursements and expenses of the Trustee's
agents and counsel.

     The Authority shall indemnify the Trustee against any and all losses,
liabilities or expenses incurred by it arising out of or in connection with the
acceptance or administration of its duties under this Indenture, including the
costs and expenses of enforcing this Indenture against the Authority (including
this Section 7.07) and defending itself against any claim (whether asserted by
the Authority or any Holder or any other person) or liability in connection with
the exercise or performance of any of its powers or duties hereunder, except to
the extent any such loss, liability or expense may be attributable to its
negligence or bad faith. The Trustee shall notify the Authority promptly of any
claim for which it may seek indemnity. Failure by the Trustee to so notify the
Authority shall not relieve the Authority of its obligations hereunder. The
Authority shall defend the claim and the Trustee shall cooperate in the defense.
The Trustee may have separate counsel and the Authority shall pay the reasonable
fees and expenses of such counsel. The Authority need not pay for any settlement
made without its consent, which consent shall not be unreasonably withheld.

     The obligations of the Authority under this Section 7.07 shall survive the
satisfaction and discharge of this Indenture.


                                       64
                                                                    Senior Notes
<PAGE>
 
     To secure the Authority's payment obligations in this Section 7.07, the
Trustee shall have a Lien prior to the Senior Notes on all money or property
held or collected by the Trustee, except that held in trust to pay principal and
interest on particular Senior Notes. Such Lien shall survive the satisfaction
and discharge of this Indenture.

     When the Trustee incurs expenses or renders services after an Event of
Default specified in Section 6.01(g) or (h) hereof occurs, the expenses and the
compensation for the services (including the fees and expenses of its agents and
counsel) are intended to constitute expenses of administration under any
Bankruptcy Law.

Section 7.08.  Replacement of Trustee.

     A resignation or removal of the Trustee and appointment of a successor
Trustee shall become effective only upon the successor Trustee's acceptance of
appointment as provided in this Section.

     The Trustee may resign in writing at any time and be discharged from the
trust hereby created by so notifying the Authority. The Holders of a majority in
principal amount of the then outstanding Senior Notes may remove the Trustee by
so notifying the Trustee and the Authority in writing. The Authority may remove
the Trustee if:

     (a) the Trustee fails to comply with Section 7.10 hereof;

relief is entered with respect to the Trustee under any Bankruptcy Law;

     (c) a custodian or public officer takes charge of the Trustee or its
property; or

     (d) the Trustee becomes incapable of acting.

     If the Trustee resigns or is removed or if a vacancy exists in the office
of Trustee for any reason, the Authority shall promptly appoint a successor
Trustee. Within one year after the successor Trustee takes office, the Holders
of a majority in principal amount of the then outstanding Senior Notes may
appoint a successor Trustee to replace the successor Trustee appointed by the
Authority.

     If any Gaming Regulatory Authority requires a Trustee to be approved,
licensed or qualified and the Trustee fails or declines to do so, such approval,
license or qualification shall be obtained upon the request of, and at the
expense of, the Authority unless the Trustee declines to do so, or, if the
Trustee's relationship with either the Authority may, in the Authority's
reasonable discretion, jeopardize any material gaming license or franchise or
right or approval granted thereto, the Trustee shall resign, and, in addition,
the Trustee may at its option resign if the Trustee in its sole discretion
determines not to be so approved, licensed or qualified.

     If a successor Trustee does not take office within 60 days after the
retiring Trustee resigns or is removed, the retiring Trustee, the Authority, or
the Holders of at least a majority in principal amount of the then outstanding
Senior Notes may petition any court of competent jurisdiction for the
appointment of a successor Trustee.

     If the Trustee, after written request by the Holders of a majority in
principal amount the then outstanding Senior Notes, fails to comply with Section
7.10, such Holder may petition any court of competent jurisdiction for the
removal of the Trustee and the appointment of a successor Trustee.

                                                                    Senior Notes
<PAGE>
 
     A successor Trustee shall deliver a written acceptance of its appointment
to the retiring Trustee and to the Authority. Thereupon, the resignation or
removal of the retiring Trustee shall become effective, and the successor
Trustee shall have all the rights, powers and duties of the Trustee under this
Indenture. The successor Trustee shall mail a notice of its succession to
Holders. The retiring Trustee shall promptly transfer all property held by it as
Trustee to the successor Trustee, provided all sums owing to the Trustee
hereunder have been paid and subject to the Lien provided for in Section 7.07
hereof. Notwithstanding replacement of the Trustee pursuant to this Section
7.08, the Authority's obligations under Section 7.07 hereof shall continue for
the benefit of the retiring Trustee.

Section 7.09.  Successor Trustee by Merger, etc.

     If the Trustee consolidates, merges or converts into, or transfers all or
substantially all of its corporate trust business to, another corporation, the
successor corporation without any further act shall be the successor Trustee.

Section 7.10.  Eligibility; Disqualification.

     There shall at all times be a Trustee hereunder that is a corporation
organized and doing business under the laws of the United States of America or
of any state thereof that is authorized under such laws to exercise corporate
trustee power, that is subject to supervision or examination by federal or state
authorities and that has a combined capital and surplus of at least $100 million
as set forth in its most recent published annual report of condition.

     This Indenture shall always have a Trustee who satisfies the requirements
of TIA ss.310(a)(1), (2) and (5). The Trustee is subject to TIA ss.310(b).

Section 7.11.  Preferential Collection of Claims Against Authority.

     The Trustee is subject to TIA ss. 311(a), excluding any creditor
relationship listed in TIA ss. 311(b). A Trustee who has resigned or been
removed shall be subject to TIA ss. 311(a) to the extent indicated therein.

Section 8.01.  Option to Effect Legal Defeasance or Covenant Defeasance.

     The Authority may, at the option of its Management Board, evidenced by a
resolution set forth in an Officers' Certificate, at any time, elect to have
either Section 8.02 or 8.03 hereof be applied to all outstanding Senior Notes
upon compliance with the conditions set forth below in this Article 8.

Section 8.02.  Legal Defeasance and Discharge.

     Upon the Authority's exercise under Section 8.01 hereof of the option
applicable to this Section 8.02, the Authority shall, subject to the
satisfaction of the conditions set forth in Section 8.04 hereof, be deemed to
have been discharged from its obligations with respect to all outstanding Senior
Notes on the date the conditions set forth below are satisfied (hereinafter,
"Legal Defeasance"). For this purpose, Legal Defeasance means that the Authority
shall be deemed to have paid and discharged the entire Indebtedness represented
by the outstanding Senior Notes, which shall thereafter be deemed to be
"outstanding" only for the purposes of Section 8.05 hereof and the other
Sections of this Indenture referred to in (a) and (b) below, and to have
satisfied all its other obligations under such Senior Notes 


                                       66
                                                                    Senior Notes
<PAGE>
 
and this Indenture (and the Trustee, on demand of and at the expense of the
Authority, shall execute proper instruments acknowledging the same), except for
the following provisions which shall survive until otherwise terminated or
discharged hereunder: (a) the rights of Holders of outstanding Senior Notes to
receive solely from the trust fund described in Section 8.04 hereof, and as more
fully set forth in such Section, payments in respect of the principal of,
premium, if any, and interest on such Senior Notes when such payments are due,
(b) the Authority's obligations with respect to such Senior Notes under Article
2 and Section 4.02 hereof, (c) the rights, powers, trusts, duties and immunities
of the Trustee hereunder and the Authority's obligations in connection therewith
and (d) this Article 8. Subject to compliance with this Article 8, the Authority
may exercise its option under this Section 8.02 notwithstanding the prior
exercise of its option under Section 8.03 hereof.

Section 8.03.  Covenant Defeasance.

     Upon the Authority's exercise under Section 8.01 hereof of the option
applicable to this Section 8.03, the Authority shall, subject to the
satisfaction of the conditions set forth in Section 8.04 hereof, be released
from its obligations under the covenants contained in Sections 4.07, 4.08, 4.09,
4.10, 4.11, 4.12, 4.13, 4.14(b), 4.15, 4.16, 4.17, 4.18, 4.20, 4.21, 4.22, 4.23,
4.24, 4.25 and 4.27 hereof and Section 5.01 hereof with respect to the
outstanding Senior Notes on and after the date the conditions set forth in
Section 8.04 are satisfied (hereinafter, "Covenant Defeasance"), and the Senior
Notes shall thereafter be deemed not "outstanding" for the purposes of any
direction, waiver, consent or declaration or act of Holders (and the
consequences of any thereof) in connection with such covenants, but shall
continue to be deemed "outstanding" for all other purposes hereunder (it being
understood that such Senior Notes shall not be deemed outstanding for accounting
purposes). For this purpose, Covenant Defeasance means that, with respect to the
outstanding Senior Notes, the Authority may omit to comply with and shall have
no liability in respect of any term, condition or limitation set forth in any
such covenant, whether directly or indirectly, by reason of any reference
elsewhere herein to any such covenant or by reason of any reference in any such
covenant to any other provision herein or in any other document and such
omission to comply shall not constitute a Default or an Event of Default under
Section 6.01 hereof, but, except as specified above, the remainder of this
Indenture and such Senior Notes shall be unaffected thereby. In addition, upon
the Authority's exercise under Section 8.01 hereof of the option applicable to
this Section 8.03 hereof, subject to the satisfaction of the conditions set
forth in Section 8.04 hereof, Sections 6.01(c) through 6.01(f) and Sections

outstanding Senior Notes on the stated date for payment thereof or on the
applicable redemption date, as the case may be;

     (b) in the case of an election under Section 8.02 hereof, the Authority

the Holders of the outstanding Senior Notes will not recognize income, gain or
loss for federal income tax purposes as a result of such Legal Defeasance and

times as would have been the case if such Covenant Defeasance had not occurred;

     (d) no Default or Event of Default shall have occurred and be continuing on
the date of such deposit (other than a Default or Event of Default resulting

concerned, at any time in the period ending on the 91st day after the date of

Restricted Subsidiaries is a party or by which the Authority or any of its
Restricted Subsidiaries is bound;

     (f) the Authority must have delivered to the Trustee an Opinion of Counsel

creditors' rights generally;

Notes shall be held in trust and applied by the Trustee, in accordance with the
provisions of such Senior Notes and this Indenture, to the payment, either

     The Authority shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the cash or non-callable Government

Notes.

shall deliver or pay to the Authority from time to time upon the request of the
Authority any money or non-callable Government Securities held by it as provided
in Section 8.04 hereof which, in the opinion of a nationally recognized firm of
independent public accountants expressed in a written certification thereof
delivered to the Trustee (which may be the opinion delivered under Section
8.04(a) hereof), are in excess of the amount thereof that would then be required
to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.

interest on any Senior Note and remaining unclaimed for two years after such
principal, and premium, if any, or interest has become due and payable shall be
paid to the Authority on its request or (if then held by the Authority) shall be
discharged from such trust; and the Holder of such Senior Note shall thereafter
look only to the Authority for payment thereof, and all liability of the Trustee
or such Paying Agent with respect to such trust money, and all liability of the
Authority as trustee thereof, shall thereupon cease; provided, however, that the
Trustee or such Paying Agent, before being required to make any such repayment,
may at the expense of the Authority cause to be published once, in the New York
Times and The Wall Street Journal (national edition), notice that such money
remains unclaimed and that, after a date specified therein, which shall not be
less than 30 days from the date of such notification or publication, any
unclaimed balance of such money then remaining will be repaid to the Authority.

Section 8.07.  Reinstatement.

or non-callable Government Securities in accordance with Section 8.02 or 8.03
hereof, as the case may be, by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such
application, then the Authority's obligations under this Indenture and the
Senior Notes shall be revived and reinstated as though no deposit had occurred
pursuant to Section 8.02 or 8.03 hereof until such time as the Trustee or Paying
Agent is permitted to apply all such money in accordance with Section 8.02 or
8.03 hereof, as the case may be; provided, however, that, if the Authority makes
any payment of principal of, premium, if any, or interest on any Senior Note
following the reinstatement of its obligations, the Authority shall be
subrogated to the rights of the Holders of such Senior Notes to receive such
payment from the money held by the Trustee or Paying Agent.

                        AMENDMENT, SUPPLEMENT AND WAIVER

Section 9.01.  Without Consent of Holders of Senior Notes.

     Notwithstanding Section 9.02 of this Indenture, provided that any required
governmental approval to ensure the enforceability of the Senior Notes and this
Indenture, including that of the BIA is obtained, the Authority, the Subsidiary
Guarantors, if any, and the Trustee may amend or supplement this Indenture, the
Senior Subsidiary Guarantees, if any, or the Senior Notes without the consent of
any Holder of a Senior Note to:

     (a) cure any ambiguity, defect or inconsistency;

     (b) provide for uncertificated Senior Notes in addition to or in place of
certificated Senior Notes or to alter the provisions of Article 2 hereof
(including the related definitions) in a manner that does not materially
adversely affect any Holder;

     (c) provide for the assumption of the Authority's or a Subsidiary
Guarantor's obligations to the Holders of the Senior Notes by a successor to the
Authority or such Subsidiary Guarantor;

     (d) make any change that would provide any additional rights or benefits to
the Holders of the Senior Notes or that does not adversely affect the legal
rights hereunder of any Holder of the Senior Notes;

     (e) comply with requirements of the SEC in order to effect or maintain the
qualification of this Indenture under the TIA; or

     (f) allow any Subsidiary to execute a supplemental indenture and/or a
Senior Subsidiary Guarantee with respect to the Senior Notes.

     Upon the request of the Authority accompanied by a resolution of its
Management Board authorizing the execution of any such amended or supplemental
Indenture, and upon receipt by the Trustee of the documents described in Section
7.02 hereof, the Trustee shall join with the Authority and the Subsidiary
Guarantors, if any, in the execution of any amended or supplemental Indenture
authorized or permitted by the terms of this Indenture and to make any further
appropriate agreements and stipulations that may be therein contained, but the
Trustee shall not be obligated to enter into such amended or supplemental
Indenture that affects its own rights, duties or immunities under this Indenture
or otherwise.

Section 9.02.  With Consent of Holders of Senior Notes.

     (a) Except as provided below in this Section 9.02, the Authority and the
Trustee may amend or supplement this Indenture (including Sections 3.10 and 4.10
hereof), the Senior Subsidiary Guarantees, if any, and the Senior Notes may be
amended or supplemented:

     (i) with the consent of the Holders of at least a majority in principal
amount of the Senior Notes then outstanding voting as a single class (including
consents obtained in connection with a tender offer or exchange offer for, or
purchase of, the Senior Notes), and, subject to Sections 6.04 and 6.07 hereof,
any existing Default or Event of Default (other than a Default or Event of
Default in the payment of the principal of, premium, if any, or interest on the
Senior Notes, except a payment default resulting from an acceleration that has
been rescinded) or compliance with any provision of this Indenture, the


                                       70
                                                                    Senior Notes
<PAGE>
 
Senior Subsidiary Guarantees or the Senior Notes may be waived with the consent
of the Holders of a majority in principal amount of the then outstanding Senior
Notes voting as a single class (including consents obtained in connection with a
tender offer or exchange offer for, or purchase of, the Senior Notes);

     (ii) without the consent of at least 66 2/3% of the aggregate principal
amount of Senior Notes then outstanding (including consents obtained in
connection with a tender offer or exchange offer for, or purchase of, such
Senior Notes), no waiver or amendment to this Indenture may make a change in the
provisions of Section 4.15 hereof that adversely affects the rights of any
Holder of Senior Notes.

     (b) Section 2.08 hereof shall determine which Senior Notes are considered
to be "outstanding" for purposes of this Section 9.02.

     (c) Upon the request of the Authority accompanied by a resolution of its
Management Board authorizing the execution of any such amended or supplemental
Indenture, and upon the filing with the Trustee of evidence satisfactory to the
Trustee of the consent of the Holders of Senior Notes as aforesaid, and upon
receipt by the Trustee of the documents described in Section 7.02 hereof, the
Trustee shall join with the Authority in the execution of such amended or
supplemental Indenture unless such amended or supplemental Indenture directly
affects the Trustee's own rights, duties or immunities under this Indenture or
otherwise, in which case the Trustee may in its discretion, but shall not be
obligated to, enter into such amended or supplemental Indenture.

     (d) It shall not be necessary for the consent of the Holders of Senior
Notes under this Section 9.02 to approve the particular form of any proposed
amendment or waiver, but it shall be sufficient if such consent approves the
substance thereof.

     (e) After an amendment, supplement or waiver under this Section becomes
effective, the Authority shall mail to the Holders of Senior Notes affected
thereby a notice briefly describing the amendment, supplement or waiver. Any
failure of the Authority to mail such notice, or any defect therein, shall not,
however, in any way impair or affect the validity of any such amended or
supplemental Indenture or waiver. Subject to Sections 6.04 and 6.07 hereof, the
Holders of a majority in aggregate principal amount of the Senior Notes then
outstanding voting as a single class may waive compliance in a particular
instance by the Authority with any provision of this Indenture or the Senior
Notes. However, without the consent of each Holder affected, an amendment or
waiver under this Section 9.02 may not (with respect to any Senior Notes held by
a non-consenting Holder):

     (i) reduce the principal amount of Senior Notes whose Holders must consent
to an amendment, supplement or waiver;

     (ii) reduce the principal of or change the fixed maturity of any Senior
Note or alter or waive any of the provisions with respect to the redemption of
the Senior Notes except as provided above with respect to Sections 3.10, 4.10
and 4.15 hereof;

     (iii) reduce the rate of or change the time for payment of interest,
including default interest, on any Senior Note;

     (iv) waive a Default or Event of Default in the payment of principal of or
premium, if any, or interest on the Senior Notes (except a rescission of
acceleration of the Senior Notes by the Holders of at least a majority in
aggregate principal amount of the then outstanding Senior Notes and a waiver of
the payment default that resulted from such acceleration);


                                       71
                                                                    Senior Notes
<PAGE>
 
     (v) make any Senior Note payable in money other than that stated in the
Senior Notes;

     (vi) make any change in the provisions of this Indenture relating to
waivers of past Defaults or the rights of Holders of Senior Notes to receive
payments of principal of or interest on the Senior Notes;

     (vii) waive a redemption payment with respect to any Note (other than a
payment required by Sections 3.10, 4.10 and 4.15 hereof);

     (viii) make any change in Section 6.04 or 6.07 hereof or in the foregoing
amendment and waiver provisions; or

     (ix) release any Subsidiary Guarantor from any of its obligations under its
Senior Subsidiary Guarantee or this Indenture, except in accordance with the
terms of its Senior Subsidiary Guarantee.

Section 9.03.  Compliance with Trust Indenture Act.

     Every amendment or supplement to this Indenture or the Senior Notes shall
be set forth in a amended or supplemental Indenture that complies with the TIA
as then in effect.

Section 9.04.  Revocation and Effect of Consents.

     Until an amendment, supplement or waiver becomes effective, a consent to it
by a Holder of a Senior Note is a continuing consent by the Holder of a Senior
Note and every subsequent Holder of a Senior Note or portion of a Senior Note
that evidences the same debt as the consenting Holder's Senior Note, even if
notation of the consent is not made on any Senior Note. However, any such Holder
of a Senior Note or subsequent Holder of a Senior Note may revoke the consent as
to its Senior Note if the Trustee receives written notice of revocation before
the date the waiver, supplement or amendment becomes effective. An amendment,
supplement or waiver becomes effective in accordance with its terms and
thereafter binds every Holder.

Section 9.05.  Notation on or Exchange of Senior Notes.

     The Trustee may place an appropriate notation about an amendment,
supplement or waiver on any Senior Note thereafter authenticated. The Authority
in exchange for all Senior Notes may issue and the Trustee shall, upon receipt
of an Authentication Order, authenticate new Senior Notes that reflect the
amendment, supplement or waiver.

     Failure to make the appropriate notation or issue a new Senior Note shall
not affect the validity and effect of such amendment, supplement or waiver.

Section 9.06.  Trustee to Sign Amendments, etc.

     The Trustee shall sign any amended or supplemental Indenture authorized
pursuant to this Article Nine if the amendment or supplement does not adversely
affect the rights, duties, liabilities or immunities of the Trustee. The
Authority may not sign an amendment or supplemental Indenture until the
Management Board approves it. In executing any amended or supplemental
indenture, the Trustee shall be entitled to receive and (subject to Section 7.01
hereof) shall be fully protected in relying upon, in addition to the documents
required by Section 11.04 hereof, an Officer's Certificate and an Opinion of
Counsel stating that the execution of such amended or supplemental indenture is
authorized or permitted by this Indenture.

other than a liability that the Authority is permitted or not prohibited from
incurring on its own behalf under this Indenture.

     (c) In the event that the Tribe receives any payment from the Authority at

any of the Tribe's representatives, political subunits, agencies,
instrumentalities or councils to, exercise any power of eminent domain over the
property that is the subject of the Lease (other than any such exercise that
would not materially adversely affect the economic rights and benefits of the
Trustee or the Holders thereunder). Except as required by federal or state law,
the Tribe will not enact any statute, law, ordinance or rule that would have a
material adverse affect on the rights of the Trustee or the Holders under this

<PAGE>
 
the Senior Notes, and award and enforce the award of damages owing as a
consequence of a breach thereof, whether such award is the product of
litigation, administrative proceedings, or arbitration; (ii) determine whether

damages owing as a consequence thereof; (ii) determine whether any consent or
approval of the Tribe or the Authority has been unreasonably withheld; and (iii)

action, or mandating or obligating the Tribe or the Authority to take any
action, including a judgment compelling the Tribe or the Authority to submit to
binding arbitration.

                Stockholders.

     1. INTEREST.

     (a) The Mohegan Tribal Gaming Authority (the "Authority"), promises to pay
interest on the principal amount of this Senior Note at 8 1/8% per annum from
March 3, 1999 until maturity. The


                                     A-1-2
                                                                    Senior Notes
<PAGE>
 
Authority will pay interest and Additional Interest, if any, semi-annually in
arrears on January 1 and July 1 of each year, or if any such day is not a
Business Day, on the next succeeding Business Day (each an "Interest Payment
Date"). Interest on the Senior Notes will accrue from the most recent date to
which interest has been paid or, if no interest has been paid, from the date of
issuance; provided that if there is no existing Default in the payment of
interest, and if this Senior Note is authenticated between a record date
referred to on the face hereof and the next succeeding Interest Payment Date,
interest shall accrue from such next succeeding Interest Payment Date; provided,
further, that the first Interest Payment Date shall be July 1, 1999. The
Authority shall pay interest (including post-petition interest in any proceeding
under any Bankruptcy Law) on overdue principal and premium, if any, from time to
time on demand at a rate that is 1% per annum in excess of the rate then in
effect; it shall pay interest (including post-petition interest in any
proceeding under any Bankruptcy Law) on overdue installments of interest and
Additional Interest, if any, (without regard to any applicable grace periods)
from time to time on demand at the same rate to the extent lawful. Interest will
be computed on the basis of a 360-day year of twelve 30-day months.

     (b) The Holder of this Senior Note is entitled to the benefits of the
Senior Registration Rights Agreement dated as of the date hereof, among the
Authority and the Initial Purchasers named therein (the "Senior Registration
Rights Agreement"). If (i) the Authority fails to file any of the Registration
Statements required by the Registration Rights Agreements on or before the date
specified for such filing, (ii) any of such Registration Statements is not
declared effective by the Commission on or prior to the date specified for such
effectiveness (the "Effectiveness Target Date"), (iii) the Authority fails to
consummate the Exchange Offer within 30 business days of the Effectiveness
Target Date with respect to the Exchange Offer Registration Statement, or (iv)
the Shelf Registration Statement or the Exchange Offer Registration Statement is
declared effective but thereafter ceases to be effective or usable in connection
with resales of Transfer Restricted Securities during the periods specified in
the Registration Rights Agreement (each such event referred to in clauses (i)
through (iv) above a "Registration Default"), then the Authority will pay
Additional Interest to each Holder of Senior Notes, with respect to the first
90-day period immediately following the occurrence of the first Registration
Default in an amount equal to 25 basis points per 90-day period of the principal
amount of Senior Notes held by such Holder. The amount of the Additional
Interest will increase by an additional 25 basis points with respect to each
subsequent 90-day period until all Registration Defaults have been cured, up to
a maximum amount of Additional Interest of 1% per annum of the principal amount
of Senior Notes.

     (A) Except as expressly provided in this paragraph 1(b), Additional
Interest shall be treated as interest and any date on which Additional Interest
is due and payable shall be treated as an Interest Payment Date for all purposes
under this Senior Note and the Indenture.

     (B) In the event that the Authority is required to pay Additional Interest
pursuant to this paragraph 1(b), the Authority shall notify the Trustee in
writing at least 15 days prior to the first Interest Payment Date upon which
such Additional Interest is due; provided that, in the event that the obligation
to pay such Additional Interest occurs less than 15 days prior to such
Additional Interest Date, such notice shall be provided by the Authority to the
Trustee as soon as reasonably practicable prior to such Interest Payment Date.

     2. METHOD OF PAYMENT. The Authority will pay interest on the Senior Notes
(except defaulted interest) and Additional Interest, if any, to the Persons who
are registered Holders of Senior Notes at the close of business on the December
15 or June 15 next preceding the Interest Payment Date, even if such Senior
Notes are canceled after such record date and on or before such Interest Payment
Date, except as provided in Section 2.12 of the Indenture with respect to
defaulted interest. The Senior Notes will be payable as to principal, premium
and Additional Interest, if any, and interest at the office or agency of the
Authority maintained for such purpose within or without the City and State of
New

                                                                    Senior Notes
<PAGE>
 
York, or, at the option of the Authority, payment of interest and Additional
Interest may be made by check mailed to the Holders at their addresses set forth
in the register of Holders, and provided that payment by wire transfer of
immediately available funds will be required with respect to principal of and
interest, premium and Additional Interest on, all Global Senior Notes and all
other Senior Notes the Holders of which shall hold at least $1.0 million in
principal amount of Senior Notes and have provided wire transfer instructions to
the Authority or the Paying Agent. Such payment shall be in such coin or
currency of the United States of America as at the time of payment is legal
tender for payment of public and private debts.

     3. PAYING AGENT AND REGISTRAR. Initially, First Union National Bank, the
Trustee under the Indenture, will act as Paying Agent and Registrar. The
Authority may change any Paying Agent or Registrar without notice to any Holder.
The Authority or any of its Subsidiaries may act in any such capacity.

     4. INDENTURE. The Authority issued the Senior Notes under an Indenture
dated as of March 3, 1999 ("Indenture") between the Authority and the Trustee.
The terms of the Senior Notes include those stated in the Indenture and those
made part of the Indenture by reference to the Trust Indenture Act of 1939, as
amended (15 U.S. Code ss.ss. 77aaa-77bbbb). The Senior Notes are subject to all
such terms, and Holders are referred to the Indenture and such Act for a
statement of such terms. To the extent any provision of this Senior Note
conflicts with the express provisions of the Indenture, the provisions of the
indenture shall govern and be controlling.

     5. OPTIONAL REDEMPTION.

     (a) The Authority may redeem all or a part of these Senior Notes upon not
less than 30 nor more than 60 days' notice, at a redemption price (expressed as
percentages of principal amount) equal to 100% of the principal amount thereof
plus the Applicable Premium, if any, plus accrued and unpaid interest thereon,
if any, to the applicable redemption date.

     (b) Notwithstanding any other provisions of Article 3 of the Indenture, if
any Gaming Regulatory Authority requires that a Holder or beneficial owner of
the Notes be licensed, qualified or found suitable under any applicable gaming
laws in order to maintain any gaming license or franchise of the Authority under
any applicable gaming laws, and the Holder or beneficial owner fails to apply
for a license, qualification or finding of suitability within 30 days after
being requested to do so by such Gaming Regulatory Authority (or such lesser
period that may be required by such Gaming Regulatory Authority) or if such
Holder or beneficial owner is not so licensed, qualified or found suitable, the
Authority has the right, at its option, (i) to require such Holder or beneficial
owner to dispose of such Holder's or beneficial owner's Senior Notes within 30
days of receipt of such notice of such finding by the applicable Gaming
Regulatory Authority (or such earlier date as may be required by the applicable
Gaming Regulatory Authority) or (ii) to call for redemption of the Senior Notes
of such Holder or beneficial owner at a redemption price equal to the lesser of
(1) the principal amount thereof or (2) the price at which such Holder or
beneficial owner acquired the Senior Notes or (3) the current market price of
the Senior Notes, together with, in either case, accrued and unpaid interest and
Additional Interest, if any, to the earlier of the date of redemption or the
date of the finding of unsuitability by such Gaming Regulatory Authority, which
may be less than 30 days following the notice of redemption if so ordered by
such Gaming Regulatory Authority. The Authority shall not be required to pay or
reimburse any Holder or beneficial owner of Senior Notes who is required to
apply for any such license, qualification or finding of suitability for the
costs of the licensure or investigation for such qualification or finding of
suitability. Such expenses shall be the obligation of such Holder or beneficial
owner.

                                                                    Senior Notes
<PAGE>
 
     6. MANDATORY REDEMPTION.

     Except as set forth in paragraph 7 below, the Authority shall not be
required to make mandatory redemption payments with respect to the Senior Notes.

     7. REPURCHASE AT OPTION OF HOLDER.

     (a) If there is a Change of Control, the Authority shall be required to
make an offer (a "Change of Control Offer") to repurchase all or any part (equal
to $1,000 or an integral multiple thereof) of each Holder's Senior Notes at a
purchase price equal to 101% of the aggregate principal amount thereof plus
accrued and unpaid interest and Additional Interest thereon, if any, to the date
of purchase (the "Change of Control Payment"). Within 20 Business Days following
any Change of Control, the Authority shall mail a notice to each Holder setting
forth the procedures governing the Change of Control Offer as required by the
Indenture.

     (b) If the Authority or a Subsidiary consummates any Asset Sales, within
five Business Days of each date on which the aggregate amount of Excess Proceeds
exceeds $15.0 million, the Authority shall commence an offer to all Holders of
Senior Notes (as "Asset Sale Offer") pursuant to Section 3.10 of the Indenture
to purchase the maximum principal amount of Senior Notes that may be purchased
out of the Excess Proceeds at an offer price in cash in an amount equal to 100%
of the principal amount thereof plus accrued and unpaid interest and Additional
Interest thereon, if any, to the date fixed for the closing of such offer, in
accordance with the procedures set forth in the Indenture. To the extent that
the aggregate amount of Senior Notes tendered pursuant to an Asset Sale Offer is
less than the Excess Proceeds, the Authority (or such Subsidiary) may use such
deficiency for any purpose not otherwise permitted by the Indenture. If the
aggregate principal amount of Senior Notes surrendered by Holders thereof
exceeds the amount of Excess Proceeds, the Trustee shall select the Senior Notes
to be purchased on a pro rata basis. Holders of Senior Notes that are the
subject of an offer to purchase will receive an Asset Sale Offer from the
Authority prior to any related purchase date and may elect to have such Senior
Notes purchased by completing the form entitled "Option of Holder to Elect
Purchase" on the reverse of the Senior Notes.

     8. NOTICE OF REDEMPTION. Notice of redemption will be mailed at least 30
days but not more than 60 days before the redemption date to each Holder whose
Senior Notes are to be redeemed at its registered address. Senior Notes in
denominations larger than $1,000 may be redeemed in part but only in whole
multiples of $1,000, unless all of the Senior Notes held by a Holder are to be
redeemed. On and after the redemption date interest ceases to accrue on Senior
Notes or portions thereof called for redemption.

     9. DENOMINATIONS, TRANSFER, EXCHANGE. The Senior Notes are in registered
form without coupons in denominations of $1,000 and integral multiples of
$1,000. The transfer of Senior Notes may be registered and Senior Notes may be
exchanged as provided in the Indenture. The Registrar and the Trustee may
require a Holder, among other things, to furnish appropriate endorsements and
transfer documents and the Authority may require a Holder to pay any taxes and
fees required by law or permitted by the Indenture. The Authority need not
exchange or register the transfer of any Senior Note or portion of a Senior Note
selected for redemption, except for the unredeemed portion of any Senior Note
being redeemed in part. Also, the Authority need not exchange or register the
transfer of any Senior Notes for a period of 15 days before a selection of
Senior Notes to be redeemed or during the period between a record date and the
corresponding Interest Payment Date.

     10. PERSONS DEEMED OWNERS. The registered Holder of a Senior Note may be
treated as its owner for all purposes.

<PAGE>
 
     11. AMENDMENT, SUPPLEMENT AND WAIVER. Subject to certain exceptions, the
Indenture, the Senior Subsidiary Guarantees or the Senior Notes may be amended
or supplemented with the consent of the Holders of at least a majority in
principal amount of the then outstanding Senior Notes voting as a single class,
and any existing default or compliance with any provision of the Indenture, the
Senior Subsidiary Guarantees or the Senior Notes may be waived with the consent
of the Holders of a majority in principal amount of the then outstanding Senior
Notes voting as a single class. Without the consent of any Holder of a Senior
Note, the Indenture, the Senior Subsidiary Guarantees or the Senior Notes may be
amended or supplemented to cure any ambiguity, defect or inconsistency, to
provide for uncertificated Senior Notes in addition to or in place of
certificated Senior Notes, to provide for the assumption of the Authority's or
Subsidiary Guarantor's obligations to Holders of the Senior Notes by a successor
to the Authority or such Subsidiary Guarantor, to make any change that would
provide any additional rights or benefits to the Holders of the Senior Notes or
that does not adversely affect the legal rights under the Indenture of any such
Holder, to comply with the requirements of the SEC in order to effect or
maintain the qualification of the Indenture under the Trust Indenture Act, or to
allow any Subsidiary Guarantor to execute a supplemental indenture to the
Indenture and/or a Senior Subsidiary Guarantee with respect to the Senior Notes
provided that the Authority has obtained any required government approval to
ensure the enforceability of the Senior Notes and the Indenture.

     12. DEFAULTS AND REMEDIES. Events of Default include: (i) default for 30
days in the payment when due of interest or Additional Interest on the Senior
Notes; (ii) default in payment when due of principal of or premium, if any, on
the Senior Notes when the same becomes due and payable at maturity, upon

with Section 4.10 or 5.01 of the Indenture; (iv) failure by the Authority or any

amount of the Senior Notes then outstanding voting as a single class or (B) any
other covenant, representation, warranty or other agreement in the Indenture or
the Senior Notes for 60 days after notice to the Authority by the Trustee or the
Holders of at least 25% in aggregate principal amount of the Senior Notes then
outstanding voting as a single class; (v) default under certain other agreements
relating to Indebtedness of the Authority or any of its Restricted Subsidiaries
which default results in the acceleration of such Indebtedness prior to its
express maturity; (vi) certain final judgments for the payment of money that
remain undischarged for a period of 60 days; (vii) certain events of bankruptcy
or insolvency with respect to the Authority or any of its Restricted
Subsidiaries; (viii) revocation, termination, suspension or other cessation of
effectiveness of any Gaming License which results in the cessation or suspension
of gaming operations for a period of more than 90 consecutive days at the
Resort; (ix) cessation of gaming operations for a period of more than 90
consecutive days at the Resort (other than as a result of a casualty loss); (x)
the Lease ceases to be in full force and effect; (xi) except as permitted by the
Indenture, any Senior Subsidiary Guarantee shall be held in any judicial
proceeding to be unenforceable or invalid or shall cease for any reason to be in
full force and effect or any Subsidiary Guarantor or any Person acting on its
behalf shall deny or disaffirm its obligations under such Subsidiary Guarantor's
Senior Subsidiary Guarantee; and (xii) failure by the Tribe to comply with the
provisions of Article 10 of the Indenture for 30 days after notice to the
Authority and the Tribe by the Trustee or the Holders of at least 25% in
aggregate principal amount of the Senior Notes then outstanding voting as a
single class. If any Event of Default occurs and is continuing, the Trustee or
the Holders of at least 25% in principal amount of the then outstanding Senior
Notes may declare all the Senior Notes to be due and payable. Notwithstanding
the foregoing, in the case of an Event of Default arising from certain events of
bankruptcy or insolvency, all outstanding Senior Notes will become due and
payable without further action or notice. Holders may not enforce the Indenture
or the Senior Notes except as provided in the Indenture. Subject to certain
limitations, Holders of a majority in principal amount of the then outstanding
Senior Notes may direct the Trustee in its exercise of any trust or power. The
Trustee may withhold from Holders of the Senior Notes notice of any

                                                                    Senior Notes
<PAGE>
 
continuing Default or Event of Default (except a Default or Event of Default
relating to the payment of principal or interest) if it determines that
withholding notice is in their interest. The Holders of a majority in aggregate
principal amount of the Senior Notes then outstanding by notice to the Trustee
may on behalf of the Holders of all of the Senior Notes waive any existing
Default or Event of Default and its consequences under the Indenture except a
continuing Default or Event of Default in the payment of interest on, or the
principal of, the Senior Notes. The Authority is required to deliver to the
Trustee annually a statement regarding compliance with the Indenture, and the
Authority is required upon becoming aware of any Default or Event of Default, to
deliver to the Trustee a statement specifying such Default or Event of Default.

     13. TRUSTEE DEALINGS WITH AUTHORITY. The Trustee, in its individual or any
other capacity, may make loans to, accept deposits from, and perform services
for the Authority or its Affiliates, and may otherwise deal with the Authority
or its Affiliates, as if it were not the Trustee.

     14. NO RECOURSE AGAINST OTHERS. A controlling person, director, officer,
employee or holder of an Ownership Interest of the Authority, as such, shall not
have any liability for any obligations of the Authority under the Senior Notes
or the Indenture or for any claim based on, in respect of, or by reason of, such
obligations or their creation. Each Holder by accepting a Senior Note waives and
releases all such liability. The waiver and release are part of the
consideration for the issuance of the Senior Notes.

     15. AUTHENTICATION. This Senior Note shall not be valid until authenticated
by the manual signature of the Trustee or an authenticating agent.

     16. ABBREVIATIONS. Customary abbreviations may be used in the name of a
Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (=
tenants by the entireties), JT TEN (= joint tenants with right of survivorship
and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts
to Minors Act).

     17. ADDITIONAL RIGHTS OF HOLDERS OF RESTRICTED GLOBAL SENIOR NOTES AND
RESTRICTED DEFINITIVE SENIOR NOTES. In addition to the rights provided to
Holders of Senior Notes under the Indenture, Holders of Restricted Global Senior
Notes and Restricted Definitive Senior Notes shall have all the rights set forth
in the Senior Registration Rights Agreement dated as of March 3, 1999, between
the Authority and the parties named on the signature pages thereof (the "Senior
Registration Rights Agreement").

     18. CUSIP NUMBERS. Pursuant to a recommendation promulgated by the
Committee on Uniform Security Identification Procedures, the Authority has
caused CUSIP numbers to be printed on the Senior Notes and the Trustee may use
CUSIP numbers in notices of redemption as a convenience to Holders. No
representation is made as to the accuracy of such numbers either as printed on
the Senior Notes or as contained in any notice of redemption and reliance may be
placed only on the other identification numbers placed thereon.

     The Authority will furnish to any Holder upon written request and without
charge a copy of the Indenture and/or the Senior Registration Rights Agreement.
Requests may be made to:

     Capitalized terms used herein shall have the meanings assigned to them in
the Indenture referred to below unless otherwise indicated.

     1. INTEREST.

     (a) The Mohegan Tribal Gaming Authority (the "Authority"), promises to pay
interest on the principal amount of this Senior Note at 81/8% per annum from
March 3 1999 until maturity. The Authority will pay interest and Additional
Interest, if any, semi-annually in arrears on January 1 and July 1 of each year,
or if any such day is not a Business Day, on the next succeeding Business Day
(each an "Interest Payment Date"). Interest on the Senior Notes will accrue from
the most recent date to which interest has been paid or, if no interest has been
paid, from the date of issuance; provided that if there is no existing Default
in the payment of interest, and if this Senior Note is authenticated between a
record date referred to on the face hereof and the next succeeding Interest
Payment Date, interest shall accrue from such next succeeding Interest Payment
Date; provided, further, that the first Interest Payment Date shall be July 1,
1999. The Authority shall pay interest (including post-petition interest in any
proceeding under any Bankruptcy Law) on overdue principal and premium, if any,
from time to time on demand at a rate that is 1% per annum in excess of the rate
then in effect; it shall pay interest (including post-petition interest in any
proceeding under any Bankruptcy Law) on overdue installments of interest and
Additional Interest, if any, (without regard to any applicable grace periods)
from time to time on demand at the same rate to the extent lawful. Interest will
be computed on the basis of a 360-day year of twelve 30-day months.

     (b) The Holder of this Senior Note is entitled to the benefits of the
Senior Registration Rights Agreement dated as of the date hereof, among the
Authority and the Initial Purchasers named therein (the "Senior Registration
Rights Agreement"). If (i) the Authority fails to file any of the Registration
Statements required by the Registration Rights Agreements on or before the date
specified for such filing, (ii) any of such Registration Statements is not
declared effective by the Commission on or prior to the date specified for such
effectiveness (the "Effectiveness Target Date"), (iii) the Authority fails to
consummate the Exchange Offer within 30 business days of the Effectiveness
Target Date with respect to the Exchange Offer Registration Statement, or (iv)
the Shelf Registration Statement or the Exchange Offer Registration Statement is
declared effective but thereafter ceases to be effective or usable in connection
with resales of Transfer Restricted Securities during the periods specified in
the Registration Rights Agreement (each such event referred to in clauses (i)
through (iv) above a "Registration Default"), then the Authority will pay
Additional Interest to each Holder of Senior Notes, with respect to the first
90-day period immediately following the occurrence of the first Registration
Default in an amount equal to 25 basis points per 90-day period of the principal
amount of Senior Notes held by such Holder. The amount of the Additional
Interest will increase by an additional 25 basis points with respect to each
subsequent 90-day period until all Registration Defaults have been cured, up to
a maximum amount of Additional Interest of 1% per annum of the principal amount
of Senior Notes.

     (A) Except as expressly provided in this paragraph 1(b), Additional
Interest shall be treated as interest and any date on which Additional Interest
is due and payable shall be treated as an Interest Payment Date for all purposes
under this Senior Note and the Indenture.

     (B) In the event that the Authority is required to pay Additional Interest
pursuant to this paragraph 1(b), the Authority shall notify the Trustee in
writing at least 15 days prior to the first Interest 


                                     A-2-3
                                                                    Senior Notes
<PAGE>
 
Payment Date upon which such Additional Interest is due; provided that, in the
event that the obligation to pay such Additional Interest occurs less than 15
days prior to such Additional Interest Date, such notice shall be provided by
the Authority to the Trustee as soon as reasonably practicable prior to such
Interest Payment Date.

     2. METHOD OF PAYMENT. The Authority will pay interest on the Senior Notes
(except defaulted interest) and Additional Interest to the Persons who are
registered Holders of Senior Notes at the close of business on the December 15
or June 15 next preceding the Interest Payment Date, even if such Senior Notes
are canceled after such record date and on or before such Interest Payment Date,
except as provided in Section 2.12 of the Indenture with respect to defaulted
interest. The Senior Notes will be payable as to principal, premium and
Additional Interest, if any, and interest at the office or agency of the
Authority maintained for such purpose within or without the City and State of
New York, or, at the option of the Authority, payment of interest and Additional
Interest, if any, may be made by check mailed to the Holders at their addresses
set forth in the register of Holders, and provided that payment by wire transfer
of immediately available funds will be required with respect to principal of and
interest, premium and Additional Interest on, all Global Senior Notes and all
other Senior Notes the Holders of which shall hold at least $1.0 million in
principal amount of Senior Notes and have provided wire transfer instructions to
the Authority or the Paying Agent. Such payment shall be in such coin or
currency of the United States of America as at the time of payment is legal
tender for payment of public and private debts.

     3. PAYING AGENT AND REGISTRAR. Initially, First Union National Bank, the
Trustee under the Indenture, will act as Paying Agent and Registrar. The
Authority may change any Paying Agent or Registrar without notice to any Holder.
The Authority or any of its Subsidiaries may act in any such capacity.

     4. INDENTURE. The Authority issued the Senior Notes under an Indenture
dated as of March 3, 1999 ("Indenture") between the Authority and the Trustee.
The terms of the Senior Notes include those stated in the Indenture and those
made part of the Indenture by reference to the Trust Indenture Act of 1939, as
amended (15 U.S. Code ss.ss. 77aaa-77bbbb). The Senior Notes are subject to all
such terms, and Holders are referred to the Indenture and such Act for a
statement of such terms. To the extent any provision of this Senior Note
conflicts with the express provisions of the Indenture, the provisions of the
indenture shall govern and be controlling.

     5. OPTIONAL REDEMPTION.

     (a) The Authority may redeem all or a part of these Senior Notes upon not
less than 30 nor more than 60 days' notice, at a redemption price (expressed as
percentages of principal amount) equal to 100% of the principal amount thereof
plus the Applicable Premium, if any, plus accrued and unpaid interest thereon,
if any, to the applicable redemption date.

     (b) Notwithstanding any other provisions of Article 3 of the Indenture, if
any Gaming Regulatory Authority requires that a Holder or beneficial owner of
the Notes be licensed, qualified or found suitable under any applicable gaming
laws in order to maintain any gaming license or franchise of the Authority under
any applicable gaming laws, and the Holder or beneficial owner fails to apply
for a license, qualification or finding of suitability within 30 days after
being requested to do so by such Gaming Regulatory Authority (or such lesser
period that may be required by such Gaming Regulatory Authority) or if such
Holder or beneficial owner is not so licensed, qualified or found suitable, the
Authority has the right, at its option, (i) to require such Holder or beneficial
owner to dispose of such Holder's or beneficial owner's Senior Notes within 30
days of receipt of such notice of such finding by the applicable Gaming
Regulatory Authority (or such earlier date as may be required by the applicable 


                                     A-2-4
                                                                    Senior Notes
<PAGE>
 
Gaming Regulatory Authority); or (ii) to call for redemption of the Senior Notes
of such Holder or beneficial owner at a redemption price equal to the lesser of
(1) the principal amount thereof or (2) the price at which such Holder or
beneficial owner acquired the Senior Notes or (3) the current market price of
the Senior Notes, together with, in either case, accrued and unpaid interest and
Additional Interest, if any, to the earlier of the date of redemption or the
date of the finding of unsuitability by such Gaming Regulatory Authority, which
may be less than 30 days following the notice of redemption if so ordered by
such Gaming Regulatory Authority. The Authority shall not be required to pay or
reimburse any Holder or beneficial owner of Senior Notes who is required to
apply for any such license, qualification or finding of suitability for the
costs of the licensure or investigation for such qualification or finding of
suitability. Such expenses shall be the obligation of such Holder or beneficial
owner.

     6. MANDATORY REDEMPTION.

     Except as set forth in paragraph 7 below, the Authority shall not be
required to make mandatory redemption payments with respect to the Senior Notes.

     7. REPURCHASE AT OPTION OF HOLDER.

     (a) If there is a Change of Control, the Authority shall be required to
make an offer (a "Change of Control Offer") to repurchase all or any part (equal
to $1,000 or an integral multiple thereof) of each Holder's Senior Notes at a
purchase price equal to 101% of the aggregate principal amount thereof plus
accrued and unpaid interest and Additional Interest thereon, if any, to the date
of purchase (the "Change of Control Payment"). Within 20 Business Days following
any Change of Control, the Authority shall mail a notice to each Holder setting
forth the procedures governing the Change of Control Offer as required by the
Indenture.

     (b) If the Authority or a Subsidiary consummates any Asset Sales, within
five Business Days of each date on which the aggregate amount of Excess Proceeds
exceeds $15.0 million, the Authority shall commence an offer to all Holders of
Senior Notes (as "Asset Sale Offer") pursuant to Section 3.10 of the Indenture
to purchase the maximum principal amount of Senior Notes that may be purchased
out of the Excess Proceeds at an offer price in cash in an amount equal to 100%
of the principal amount thereof plus accrued and unpaid interest and Additional
Interest thereon, if any, to the date fixed for the closing of such offer, in
accordance with the procedures set forth in the Indenture. To the extent that
the aggregate amount of Senior Notes tendered pursuant to an Asset Sale Offer is
less than the Excess Proceeds, the Authority (or such Subsidiary) may use such
deficiency for any purpose not otherwise permitted by the Indenture. If the
aggregate principal amount of Senior Notes surrendered by Holders thereof
exceeds the amount of Excess Proceeds, the Trustee shall select the Senior Notes
to be purchased on a pro rata basis. Holders of Senior Notes that are the
subject of an offer to purchase will receive an Asset Sale Offer from the
Authority prior to any related purchase date and may elect to have such Senior
Notes purchased by completing the form entitled "Option of Holder to Elect
Purchase" on the reverse of the Senior Notes.

     8. NOTICE OF REDEMPTION. Notice of redemption will be mailed at least 30
days but not more than 60 days before the redemption date to each Holder whose
Senior Notes are to be redeemed at its registered address. Senior Notes in
denominations larger than $1,000 may be redeemed in part but only in whole
multiples of $1,000, unless all of the Senior Notes held by a Holder are to be
redeemed. On and after the redemption date interest ceases to accrue on Senior
Notes or portions thereof called for redemption.

     9. DENOMINATIONS, TRANSFER, EXCHANGE. The Senior Notes are in registered
form without coupons in denominations of $1,000 and integral multiples of

that does not adversely affect the legal rights under the Indenture of any such
Holder, to comply with the requirements of the SEC in order to effect or
maintain the qualification of the Indenture under the Trust Indenture Act, or to
allow any Subsidiary Guarantor to execute a supplemental indenture to the
Indenture and/or a Senior Subsidiary Guarantee with respect to the Senior Notes
provided that the Authority has obtained any required government approval to
ensure the enforceability of the Senior Notes and the Indenture.

its Restricted Subsidiaries which default results in the acceleration of such
Indebtedness prior to its express maturity; (vi) certain final judgments for the
payment of money that remain undischarged for a period of 60 days; (vii) certain
events of bankruptcy or insolvency with respect to the Authority or any of its

behalf shall deny or disaffirm its obligations under such Subsidiary Guarantor's
Senior Subsidiary Guarantee; and (xii) failure by the Tribe to comply with the
provisions of Article 10 of the Indenture for 30 days after notice to the
Authority and the Tribe by the Trustee or the Holders of at least 25% in
aggregate principal amount of the Senior Notes then outstanding voting as a
single class. If any Event of Default occurs and is continuing, the Trustee or
the Holders of at least 25% in principal amount of the then outstanding Senior
Notes may declare all the Senior Notes to be due and payable. Notwithstanding
the foregoing, in the case of an Event of Default arising from certain events of
bankruptcy or insolvency, all outstanding Senior Notes will become due and
payable without further action or notice. Holders may not enforce the Indenture
or the Senior Notes except as provided in the Indenture. Subject to certain
limitations, Holders of a majority in principal amount of the then outstanding
Senior Notes may direct the Trustee in its exercise of any trust or power. The
Trustee may withhold from Holders of the Senior Notes notice of any continuing
Default or Event of Default (except a Default or Event of Default relating to
the payment of principal or interest) if it determines that withholding notice
is in their interest. The Holders of a majority in aggregate principal amount of
the Senior Notes then outstanding by notice to the Trustee may on behalf of the
Holders of all of the Senior Notes waive any existing Default or Event of
Default and its consequences under the Indenture except a continuing Default or
Event of Default in the payment of interest on, or the principal of, the Senior
Notes. The Authority is required to deliver to the Trustee annually a statement
regarding compliance with the Indenture, and the Authority is required upon
becoming aware of any Default or Event of Default, to deliver to the Trustee a
statement specifying such Default or Event of Default.

     13. TRUSTEE DEALINGS WITH AUTHORITY. The Trustee, in its individual or any
other capacity, may make loans to, accept deposits from, and perform services
for the Authority or its Affiliates, and may otherwise deal with the Authority
or its Affiliates, as if it were not the Trustee.

     14. NO RECOURSE AGAINST OTHERS. A controlling person, director, officer,
employee, or holder of an Ownership Interest of the Authority, as such, shall
not have any liability for any obligations of the Authority under the Senior
Notes or the Indenture or for any claim based on, in respect of, or by reason
of, such obligations or their creation. Each Holder by accepting a Senior Note
waives and releases all such liability. The waiver and release are part of the
consideration for the issuance of the Senior Notes.

     15. AUTHENTICATION. This Senior Note shall not be valid until authenticated
by the manual signature of the Trustee or an authenticating agent.

     16. ABBREVIATIONS. Customary abbreviations may be used in the name of a
Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (=
tenants by the entireties), JT TEN (= joint tenants with right of survivorship
and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts
to Minors Act).

     17. ADDITIONAL RIGHTS OF HOLDERS OF RESTRICTED GLOBAL SENIOR NOTES AND

the Authority and the parties named on the signature pages thereof (the "Senior
Registration Rights Agreement").

     18. CUSIP NUMBERS. Pursuant to a recommendation promulgated by the
Committee on Uniform Security Identification Procedures, the Authority has
caused CUSIP numbers to be printed on the Senior Notes and the Trustee may use
CUSIP numbers in notices of redemption as a convenience to Holders. No
representation is made as to the accuracy of such numbers either as printed on
the Senior Notes or as contained in any notice of redemption and reliance may be
placed only on the other identification numbers placed thereon.

     The Authority will furnish to any Holder upon written request and without
charge a copy of the Indenture and/or the Senior Registration Rights Agreement.

     Subsidiary Guarantor further agrees that, as between the Subsidiary
     Guarantors, on the one hand, and the Holders and the Trustee, on the other
     hand:

          accelerated as provided in Article 6 of the Indenture for the purposes
          of the Senior Subsidiary Guarantee made pursuant to this Supplemental

          preventing such acceleration in respect of the obligations guaranteed
          hereby; and

          obligations as provided in Article 6, such obligations (whether or not
          due and payable) shall forthwith become due and payable by the
          Subsidiary Guarantor for the purpose of the Senior Subsidiary
          Guarantee made pursuant to this Supplemental Indenture.

          (i) The Subsidiary Guarantor shall have the right to seek contribution
     from any other non-paying Subsidiary Guarantor, if any, so long as the
     exercise of such right does not impair the rights of the Holders under the
     Senior Subsidiary Guarantee made pursuant to this Supplemental Indenture.

          (j) The Subsidiary Guarantor covenants (to the extent that it may
     lawfully do so) that it will not at any time insist upon, or plead, or in
     any manner whatsoever claim or take the benefit or advantage of, any stay,

     force, which may affect the covenants or the performance of the Indenture
     or this Senior Subsidiary Guarantee; and the Subsidiary Guarantor (to the
     extent that it may lawfully do so) hereby expressly waives all benefit or
     advantage of any such law, and covenants that it will not hinder, delay or
     impede the execution of any power herein granted to the Trustee, but will

SECTION 2. HOLDERS

     A person is deemed to be a holder of Transfer Restricted Securities (each,
a "Holder") whenever such person owns Transfer Restricted Securities.

SECTION 3. REGISTERED EXCHANGE OFFER

     (a) Unless the Exchange Offer shall not be permitted by applicable federal
law (after the procedures set forth in Section 6(a)(i) below have been complied
with), the Authority shall (i) cause the Exchange Offer Registration Statement
to be filed with the Commission as soon as practicable after the Closing Date,
but in no event later than 90 days after the Closing Date (such 90th day being
the "Filing Deadline"), (ii) use its best efforts to cause such Exchange Offer
Registration Statement to become effective at the earliest possible time, but in
no event later than 150 days after the Closing Date (such 150th day being the
"Effectiveness Deadline"), (iii) in connection with the foregoing, (A) file all
pre-effective amendments to such Exchange Offer Registration Statement as may be
necessary in order to cause it to become effective, (B) file, if applicable, a
post-effective amendment to such Exchange Offer Registration Statement pursuant
to Rule 430A under the Act and (C) cause all necessary filings, if any, in
connection with the registration and qualification of the Senior Exchange Notes
to be made under the Blue Sky laws of such jurisdictions as are necessary to
permit Consummation of the Exchange Offer, and (iv) upon the effectiveness of
such Exchange Offer Registration Statement, commence and Consummate the Exchange
Offer. The Exchange Offer shall be on the appropriate form permitting (i)
registration of the Senior Exchange Notes to be offered in exchange for the
Initial Senior Notes that are Transfer Restricted Securities and (ii) resales of
Senior Exchange Notes by Broker-Dealers that tendered into the Exchange Offer
Initial Senior Notes that such Broker-Dealer acquired for its own account as a
result of market making activities or other trading activities (other than
Initial Senior Notes acquired directly from the Authority or any of its
Affiliates) as contemplated by Section 3(c) below.

     (b) The Authority shall use its best efforts to cause the Exchange Offer
Registration Statement to be effective continuously, and shall keep the Exchange
Offer open for a period of not less than the minimum period required under
applicable federal and state securities laws to Consummate the Exchange Offer;
provided, however, that in no event shall such period be less than 20 Business
Days. The Authority shall cause the Exchange Offer to comply with all applicable
federal and state securities laws. No securities other than the Senior Exchange
Notes and the Senior Subordinated Exchange Notes shall be included in the
Exchange Offer Registration Statement. The Authority shall use its best efforts
to cause the Exchange Offer to be Consummated on the earliest practicable date
after the Exchange Offer Registration Statement has become effective, but in no
event later than 30 Business Days thereafter (such 30th day being the
"Consummation Deadline").

     (c) The Authority shall include a "Plan of Distribution" section in the
Prospectus contained in the Exchange Offer Registration Statement and indicate
therein that any Broker-Dealer who holds Transfer Restricted Securities that
were acquired for the account of such Broker-Dealer as a result of market-making
activities or other trading activities (other than Initial Senior Notes acquired
directly from the Authority or any Affiliate of the Authority), may exchange
such Transfer Restricted Securities pursuant to the Exchange


                                        3
<PAGE>
 
Offer. Such "Plan of Distribution" section shall also contain all other
information with respect to such sales by such Broker-Dealers that the
Commission may require in order to permit such sales pursuant thereto, but such
"Plan of Distribution" shall not name any such Broker-Dealer or disclose the
amount of Transfer Restricted Securities held by any such Broker-Dealer, except
to the extent required by the Commission as a result of a change in policy,
rules or regulations after the date of this Agreement.

     Because such Broker-Dealer may be deemed to be an "underwriter" within the
meaning of the Act and must, therefore, deliver a prospectus meeting the
requirements of the Act in connection with its initial sale of any Senior
Exchange Notes received by such Broker-Dealer in the Exchange Offer, the
Authority shall permit the use of the Prospectus contained in the Exchange Offer
Registration Statement by such Broker-Dealer to satisfy such prospectus delivery
requirement. To the extent necessary to ensure that the prospectus contained in
the Exchange Offer Registration Statement is available for sales of Senior
Exchange Notes by Broker-Dealers, the Authority agrees to use its best efforts
to keep the Exchange Offer Registration Statement continuously effective,
supplemented, amended and current as required by and subject to the provisions
of Section 6(a) and (c) hereof and in conformity with the requirements of this
Agreement, the Act and the policies, rules and regulations of the Commission as
announced from time to time, for a period of one year from the Consummation
Deadline or such shorter period as will terminate when all Transfer Restricted
Securities covered by such Registration Statement have been sold pursuant
thereto. The Authority shall provide sufficient copies of the latest version of
such Prospectus to such Broker-Dealers, promptly upon request, and in no event
later than one day after such request, at any time during such period.

SECTION 4. SHELF REGISTRATION

     (a) Shelf Registration. If (i) the Exchange Offer is not permitted by
applicable law (after the Authority has complied with the procedures set forth
in Section 6(a)(i) below) or (ii) if any Holder of Transfer Restricted
Securities shall notify the Authority within 20 Business Days following the
Consummation Deadline that (A) such Holder was prohibited by law or Commission
policy from participating in the Exchange Offer or (B) such Holder may not
resell the Senior Exchange Notes acquired by it in the Exchange Offer to the
public without delivering a prospectus and the Prospectus contained in the
Exchange Offer Registration Statement is not appropriate or available for such
resales by such Holder or (C) such Holder is a Broker-Dealer and holds Initial
Senior Notes acquired directly from the Authority or any of its Affiliates, then
the Authority shall

     (x) cause to be filed, on or prior to 30 days after the earlier of (i) the
date on which the Authority determines that the Exchange Offer Registration
Statement cannot be filed as a result of clause (a)(i) above and (ii) the date
on which the Authority receives the notice specified in clause (a)(ii) above,
(such earlier date, the "Filing Deadline"), a shelf registration statement
pursuant to Rule 415 under the Act (which may be an amendment to the Exchange
Offer Registration Statement (the "Shelf Registration Statement")), relating to
all Transfer Restricted Securities, and

     (y) shall use its best efforts to cause such Shelf Registration Statement
to become effective on or prior to 90 days after the Filing Deadline for the
Shelf Registration Statement (such 90th day the "Effectiveness Deadline").

     If, after the Authority has filed an Exchange Offer Registration Statement
that satisfies the requirements of Section 3(a) above, the Authority is required
to file and make effective a Shelf Registration Statement solely because the
Exchange Offer is not permitted under applicable federal law (i.e. clause (a)(i)
above), then the filing of the Exchange Offer Registration Statement shall be
deemed to satisfy the requirements of clause (x) above; provided that, in such
event, the Authority shall remain obligated to meet the Effectiveness Deadline
set forth in clause (y).


                                        4
<PAGE>
 
     To the extent necessary to ensure that the Shelf Registration Statement is
available for sales of Transfer Restricted Securities by the Holders thereof
entitled to the benefit of this Section 4(a) and the other securities required
to be registered therein pursuant to Section 6(b)(ii) hereof, the Authority
shall use its best efforts to keep any Shelf Registration Statement required by
this Section 4(a) continuously effective, supplemented, amended and current as
required by and subject to the provisions of Sections 6(b) and (c) hereof and in
conformity with the requirements of this Agreement, the Act and the policies,
rules and regulations of the Commission as announced from time to time, for a
period of at least two years (as extended pursuant to Section 6(c)(i)) following
the Closing Date, or such shorter period as will terminate when all Transfer
Restricted Securities covered by such Shelf Registration Statement have been
sold pursuant thereto.

     (b) Provision by Holders of Certain Information in Connection with the
Shelf Registration Statement. No Holder of Transfer Restricted Securities may
include any of its Transfer Restricted Securities in any Shelf Registration
Statement pursuant to this Agreement unless and until such Holder furnishes to
the Authority in writing, within 20 days after receipt of a request therefor,
the information specified in Item 507 or 508 of Regulation S-K, as applicable,
of the Act for use in connection with any Shelf Registration Statement or
Prospectus or preliminary Prospectus included therein. No Holder of Transfer
Restricted Securities shall be entitled to additional interest pursuant to
Section 5 hereof unless and until such Holder shall have provided all such
information. Each selling Holder agrees to furnish promptly additional
information required to be disclosed in order to make the information previously
furnished to the Authority by such Holder not materially misleading.

SECTION 5. ADDITIONAL INTEREST

     If (i) any Registration Statement required by this Agreement is not filed
with the Commission on or prior to the applicable Filing Deadline, (ii) any such
Registration Statement has not been declared effective by the Commission on or
prior to the applicable Effectiveness Deadline, (iii) the Exchange Offer has not
been Consummated on or prior to the Consummation Deadline or (iv) any
Registration Statement required by this Agreement is filed and declared
effective but shall thereafter cease to be effective or fail to be usable for
its intended purpose without being succeeded within 2 days by a post-effective
amendment to such Registration Statement that cures such failure and that is
itself declared effective within 5 days of filing such post-effective amendment
to such Registration Statement (each such event referred to in clauses (i)
through (iv), a "Registration Default"), then the Authority hereby agrees to pay
to each Holder of Transfer Restricted Securities affected thereby additional
interest in an amount equal to 25 basis points per 90-day period of the
principal amount of Transfer Restricted Securities held by such Holder for the
90-day period or portion thereof that the Registration Default continues for the
first 90-day period immediately following the occurrence of such Registration
Default. The amount of the additional interest shall increase by an additional
25 basis points with respect to each subsequent 90-day period until all
Registration Defaults have been cured, up to a maximum amount of additional
interest of 1% per annum of the principal amount of Transfer Restricted
Securities; provided that the Authority shall in no event be required to pay
additional interest for more than one Registration Default at any given time.
Notwithstanding anything to the contrary set forth herein, (1) upon filing of
the Exchange Offer Registration Statement (and/or, if applicable, the Shelf
Registration Statement), in the case of (i) above, (2) upon the effectiveness of
the Exchange Offer Registration Statement (and/or, if applicable, the Shelf
Registration Statement), in the case of (ii) above, (3) upon Consummation of the
Exchange Offer, in the case of (iii) above, or (4) upon the filing of a
post-effective amendment to the Registration Statement or an additional
Registration Statement that causes the Exchange Offer Registration Statement
(and/or, if applicable, the Shelf Registration Statement) to again be declared
effective or made usable in the case of (iv) above, the additional interest
payable with respect to the Transfer Restricted Securities as a result of such
clause (i), (ii), (iii) or (iv), as applicable, shall cease.

     All accrued additional interest shall be paid to the Holders entitled
thereto, in the manner provided for the payment of interest in the Senior Notes
Indenture and the Senior Notes, on each Interest Payment Date, as more fully set
forth in the Senior Notes Indenture and the Senior Notes. Notwithstanding the
fact
<PAGE>
 
that any securities for which additional interest is due cease to be Transfer
Restricted Securities, all obligations of the Authority to pay additional
interest with respect to securities shall survive until such time as such
obligations with respect to such securities shall have been satisfied in full.

SECTION 6. REGISTRATION PROCEDURES

     (a) Exchange Offer Registration Statement. In connection with the Exchange
Offer, the Authority shall (x) comply with all applicable provisions of Section
6(c) below, (y) use its best efforts to effect such exchange and to permit the
resale of Senior Exchange Notes by Broker-Dealers that tendered in the Exchange
Offer Initial Senior Notes that such Broker-Dealer acquired for its own account
as a result of its market making activities or other trading activities (other
than Initial Senior Notes acquired directly from the Authority or any of its
Affiliates) being sold in accordance with the intended method or methods of
distribution thereof, and (z) comply with all of the following provisions:

          (i) If, following the date hereof there has been announced a change in
     Commission policy with respect to exchange offers such as the Exchange
     Offer, that in the reasonable opinion of counsel to the Authority raises a
     substantial question as to whether the Exchange Offer is permitted by
     applicable federal law, the Authority hereby agrees to seek a no-action
     letter or other favorable decision from the Commission staff allowing the
     Authority to Consummate a Exchange Offer for such Transfer Restricted
     Securities. In connection with the foregoing, the Authority hereby agrees
     to take all actions as may be required in connection with the issuance of
     such decision, including without limitation (A) participating in telephonic
     conferences with the Commission, (B) delivering to the Commission staff an
     analysis prepared by counsel to the Authority setting forth the legal
     bases, if any, upon which such counsel has concluded that such an Exchange
     Offer should be permitted and (C) diligently pursuing a resolution (which
     need not be favorable) by the Commission staff.

          (ii) As a condition to its participation in the Exchange Offer, each
     Holder of Transfer Restricted Securities (including, without limitation,
     any Holder who is a Broker-Dealer) shall furnish, upon the request of the
     Authority, prior to the Consummation of the Exchange Offer, a written
     representation to the Authority (which may be contained in the letter of
     transmittal contemplated by the Exchange Offer Registration Statement) to
     the effect that (A) it is not an Affiliate of the Authority, (B) it is not
     engaged in, and does not intend to engage in, and has no arrangement or
     understanding with any person to participate in, a distribution of the
     Senior Exchange Notes to be issued in the Exchange Offer and (C) it is
     acquiring the Senior Exchange Notes in its ordinary course of business. As
     a condition to its participation in the Exchange Offer, each Holder using
     the Exchange Offer to participate in a distribution of the Senior Exchange
     Notes shall acknowledge and agree that, if the resales are of Senior
     Exchange Notes obtained by such Holder in exchange for Initial Senior Notes
     acquired directly from the Authority or an Affiliate thereof, it (1) could
     not, under Commission policy as in effect on the date of this Agreement,
     rely on the position of the Commission enunciated in Exxon Capital Holdings
     Corporation (available May 13, 1988) and Morgan Stanley and Co., Inc.
     (available June 5, 1991), as interpreted in the Commission's letter to
     Shearman & Sterling dated July 2, 1993, and similar no-action letters
     (including, if applicable, any no-action letter obtained pursuant to clause
     (i) above), and (2) must comply with the registration and prospectus
     delivery requirements of the Act in connection with a secondary resale
     transaction and that such a secondary resale transaction must be covered by
     an effective registration statement containing the selling security holder
     information required by Item 507 or 508, as applicable, of Regulation S-K.

          (iii) Prior to effectiveness of the Exchange Offer Registration
     Statement, the Authority shall provide a supplemental letter to the
     Commission (A) stating that the Authority is registering the Exchange Offer
     in reliance on the position of the Commission enunciated in Exxon Capital
     Holdings Corporation (available May 13, 1988), and Morgan Stanley and Co.,
     Inc. (available


                                       6
<PAGE>
 
     June 5, 1991), as interpreted in the Commission's letter to Shearman &
     Sterling dated July 2, 1993, and, if applicable, any no-action letter
     obtained pursuant to clause (i) above, (B) including a representation that
     the Authority has not entered into any arrangement or understanding with
     any person to distribute the Senior Exchange Notes to be received in the
     Exchange Offer and that, to the best of the Authority's information and
     belief, each Holder participating in the Exchange Offer is acquiring the
     Senior Exchange Notes in its ordinary course of business and has no
     arrangement or understanding with any person to participate in the
     distribution of the Senior Exchange Notes received in the Exchange Offer
     and (C) any other undertaking or representation required by the Commission
     as set forth in any no-action letter obtained pursuant to clause (i) above,
     if applicable.

     (b) Shelf Registration Statement. In connection with the Shelf Registration
Statement, the Authority shall

          (i) comply with all the provisions of Section 6(c) below and use its
     best efforts to effect such registration to permit the sale of the Transfer
     Restricted Securities being sold in accordance with the intended method or
     methods of distribution thereof (as indicated in the information furnished
     to the Authority pursuant to Section 4(b) hereof), and pursuant thereto the
     Authority will prepare and file with the Commission a Registration
     Statement relating to the registration on any appropriate form under the
     Act, which form shall be available for the sale of the Transfer Restricted
     Securities in accordance with the intended method or methods of
     distribution thereof within the time periods and otherwise in accordance
     with the provisions hereof, and

          (ii) issue, upon the request of any Holder or purchaser of Initial
     Senior Notes covered by any Shelf Registration Statement contemplated by
     this Agreement, Senior Exchange Notes having an aggregate principal amount
     equal to the aggregate principal amount of Initial Senior Notes sold
     pursuant to the Shelf Registration Statement and surrendered to the
     Authority for cancellation. The Authority shall register Senior Exchange
     Notes on the Shelf Registration Statement for this purpose and issue the
     Senior Exchange Notes to the purchaser(s) of securities subject to the
     Shelf Registration Statement in the names as such purchaser(s) shall
     designate.

     (c) General Provisions. In connection with any Registration Statement and
any related Prospectus required by this Agreement, the Authority shall

          (i) use its best efforts to keep such Registration Statement
     continuously effective and provide all requisite financial statements for
     the period specified in Section 3 or 4 of this Agreement, as applicable.
     Upon the occurrence of any event that would cause any such Registration
     Statement or the Prospectus contained therein (A) to contain an untrue
     statement of material fact or omit to state any material fact necessary to
     make the statements therein not misleading or (B) not to be effective and
     usable for resale of Transfer Restricted Securities during the period
     required by this Agreement, the Authority shall file promptly an
     appropriate amendment to such Registration Statement curing such defect,
     and, if Commission review is required, use its best efforts to cause such
     amendment to be declared effective as soon as practicable;

          (ii) prepare and file with the Commission such amendments and
     post-effective amendments to the applicable Registration Statement as may
     be necessary to keep such Registration Statement effective for the
     applicable period set forth in Section 3 or 4 hereof, as the case may be,
     cause the Prospectus to be supplemented by any required Prospectus
     supplement, and as so supplemented to be filed pursuant to Rule 424 under
     the Act, and to comply fully with Rules 424, 430A and 462, as applicable,
     under the Act in a timely manner; and comply with the provisions of the Act
     with respect to the disposition of all securities covered by such
     Registration Statement during the applicable period in accordance with the
     intended method or methods of distribution by the sellers thereof set forth
     in such Registration Statement or supplement to the Prospectus;


                                       7
<PAGE>
 
          (iii) advise each Holder promptly and, if requested by such Holder,
     confirm such advice in writing, (A) when the Prospectus or any Prospectus
     supplement or post-effective amendment has been filed, and, with respect to
     any applicable Registration Statement or any post-effective amendment
     thereto, when the same has become effective, (B) of any request by the
     Commission for amendments to the Registration Statement or amendments or
     supplements to the Prospectus or for additional information relating
     thereto, (C) of the issuance by the Commission of any stop order suspending
     the effectiveness of the Registration Statement under the Act or of the
     suspension by any state securities commission of the qualification of the
     Transfer Restricted Securities for offering or sale in any jurisdiction, or
     the initiation of any proceeding for any of the preceding purposes, (D) of
     the existence of any fact or the happening of any event that makes any
     statement of a material fact made in the Registration Statement, the
     Prospectus, any amendment or supplement thereto or any document
     incorporated by reference therein untrue, or that requires the making of
     any additions to or changes in the Registration Statement in order to make
     the statements therein not misleading, or that requires the making of any
     additions to or changes in the Prospectus in order to make the statements
     therein, in the light of the circumstances under which they were made, not
     misleading. If at any time the Commission shall issue any stop order
     suspending the effectiveness of the Registration Statement, or any state
     securities commission or other regulatory authority shall issue an order
     suspending the qualification or exemption from qualification of the
     Transfer Restricted Securities under state securities or Blue Sky laws, the
     Authority shall use its best efforts to obtain the withdrawal or lifting of
     such order at the earliest possible time;

          (iv) subject to Section 6(c)(i), if any fact or event contemplated by
     Section 6(c)(iii)(D) above shall exist or have occurred, prepare a
     supplement or post-effective amendment to the Registration Statement or
     related Prospectus or any document incorporated therein by reference or
     file any other required document so that, as thereafter delivered to the
     purchasers of Transfer Restricted Securities, the Prospectus will not
     contain an untrue statement of a material fact or omit to state any
     material fact necessary to make the statements therein, in the light of the
     circumstances under which they were made, not misleading;

          (v) furnish to each Holder in connection with such exchange or sale,
     if any, before filing with the Commission, copies of any Registration
     Statement or any Prospectus included therein or any amendments or
     supplements to any such Registration Statement or Prospectus (including all
     documents incorporated by reference after the initial filing of such
     Registration Statement), which documents will be subject to the review and
     comment of such Holders in connection with such sale, if any, for a period
     of at least five Business Days, and the Authority will use its best efforts
     to reflect in each such Registration Statement or Prospectus or any
     amendment or supplement to any such Registration Statement or Prospectus
     (including all such documents incorporated by reference) when so filed with
     the Commission, such comments proposed by such Holders. A Holder shall be
     deemed to have objected to such filing if such Registration Statement,
     amendment, Prospectus or supplement, as applicable, as proposed to be
     filed, contains an untrue statement of a material fact or omit to state any
     material fact necessary to make the statements therein not misleading or
     fails to comply with the applicable requirements of the Act;

          (vi) promptly prior to the filing of any document that is to be
     incorporated by reference into a Registration Statement or Prospectus,
     provide copies of such document to each Holder in connection with such
     exchange or sale, if any, make the Authority's representatives available
     for discussion of such document and other customary due diligence matters,
     and include such information in such document prior to the filing thereof
     as such Holders may reasonably request;

          (vii) make available, at reasonable times, for inspection by each
     Holder and any attorney or accountant retained by such Holders, all
     financial and other records, pertinent corporate documents of the Authority
     and cause the Authority's officers, board members and employees to supply
     all information reasonably requested by any such Holder, attorney or
     accountant in


                                        8
<PAGE>
 
connection with such Registration Statement or any post-effective amendment
thereto subsequent to the filing thereof and prior to its effectiveness;

          (viii) if requested by any Holders in connection with such exchange or
     sale, promptly include in any Registration Statement or Prospectus,
     pursuant to a supplement or post-effective amendment if necessary, such
     information as such Holders may reasonably request to have included
     therein, including, without limitation, information relating to the "Plan
     of Distribution" of the Transfer Restricted Securities, and make all
     required filings of such Prospectus supplement or post-effective amendment
     as soon as practicable after the Authority is notified of the matters to be
     included in such Prospectus supplement or post-effective amendment;

          (ix) furnish to each Holder in connection with such exchange or sale,
     without charge, at least one copy of the Registration Statement, as first
     filed with the Commission, and of each amendment thereto, including all
     documents incorporated by reference therein and all exhibits (including
     exhibits incorporated therein by reference);

          (x) deliver to each Holder without charge, as many copies of the
     Prospectus (including each preliminary prospectus) and any amendment or
     supplement thereto as such Persons reasonably may request; the Authority
     hereby consents to the use (in accordance with law) of the Prospectus and
     any amendment or supplement thereto by each selling Holder in connection
     with the offering and the sale of the Transfer Restricted Securities
     covered by the Prospectus or any amendment or supplement thereto;

          (xi) upon the request of any Holder, enter into such agreements
     (including underwriting agreements) and make such representations and
     warranties and take all such other actions in connection therewith in order
     to expedite or facilitate the disposition of the Transfer Restricted
     Securities pursuant to any applicable Registration Statement contemplated
     by this Agreement as may be reasonably requested by any Holder in
     connection with any sale or resale pursuant to any applicable Registration
     Statement. In such connection, the Authority shall

               (A) upon request of any Holder, furnish (or in the case of
          paragraphs (2) and (3), use its best efforts to cause to be furnished)
          to each Holder, upon Consummation of the Exchange Offer or upon the
          effectiveness of the Shelf Registration Statement, as the case may be:

                    (1) a certificate, dated such date, signed on behalf of the
               Authority by the Chairman of the Management Board confirming, as
               of the date thereof, the matters set forth in Section 6(d) of the
               Purchase Agreement and such other similar matters as such Holders
               may reasonably request;

                    (2) an opinion, dated the date of Consummation of the
               Exchange Offer or the date of effectiveness of the Shelf
               Registration Statement, as the case may be, of counsel for the
               Authority covering such matters as such Holder may reasonably
               request and are customarily given in similar offerings; and

                    (3) a customary comfort letter, dated the date of
               Consummation of the Exchange Offer, or as of the date of
               effectiveness of the Shelf Registration Statement, as the case
               may be, from the Authority's independent accountants, in the
               customary form and covering matters of the type customarily
               covered in comfort letters to underwriters in connection with
               underwritten offerings, and affirming the matters set forth in
               the comfort letters delivered pursuant to Section 6(e) of the
               Purchase Agreement; and


                                       9
<PAGE>
 
               (B) deliver such other documents and certificates as may be
          reasonably requested by the selling Holders to evidence compliance
          with the matters covered in clause (A) above and with any customary
          conditions contained in the any agreement entered into by the
          Authority pursuant to this clause (xi);

          (xii) prior to any public offering of Transfer Restricted Securities,
     cooperate with the selling Holders and their counsel in connection with the
     registration and qualification of the Transfer Restricted Securities under
     the securities or Blue Sky laws of such jurisdictions as the selling
     Holders may request and do any and all other acts or things necessary or
     advisable to enable the disposition in such jurisdictions of the Transfer
     Restricted Securities covered by the applicable Registration Statement;
     provided, however, that the Authority shall not be required to register or
     qualify as a foreign corporation where it is not now so qualified or to
     take any action that would subject it to the service of process in suits or
     to taxation, other than as to matters and transactions relating to the
     Registration Statement, in any jurisdiction where it is not now so subject;

          (xiii) in connection with any sale of Transfer Restricted Securities
     that will result in such securities no longer being Transfer Restricted
     Securities, cooperate with the Holders to facilitate the timely preparation
     and delivery of certificates representing Transfer Restricted Securities to
     be sold and not bearing any restrictive legends; and to register such
     Transfer Restricted Securities in such denominations and such names as the
     selling Holders may request at least two Business Days prior to such sale
     of Transfer Restricted Securities;

          (xiv) use its best efforts to cause the disposition of the Transfer
     Restricted Securities covered by the Registration Statement to be
     registered with or approved by such other governmental agencies or
     authorities as may be necessary to enable the seller or sellers thereof to
     consummate the disposition of such Transfer Restricted Securities, subject
     to the proviso contained in clause (xii) above;

          (xv) provide a CUSIP number for all Transfer Restricted Securities not
     later than the effective date of a Registration Statement covering such
     Transfer Restricted Securities and provide the Trustee under the Senior
     Notes Indenture with printed certificates for the Transfer Restricted
     Securities which are in a form eligible for deposit with the Depository
     Trust Company;

          (xvi) otherwise use its best efforts to comply with all applicable
     rules and regulations of the Commission, and make generally available to
     its security holders with regard to any applicable Registration Statement,
     as soon as practicable, a consolidated earnings statement meeting the
     requirements of Rule 158 (which need not be audited) covering a 12-month
     period beginning after the effective date of the Registration Statement (as
     such term is defined in paragraph (c) of Rule 158 under the Act);

          (xvii) cause the Senior Notes Indenture to be qualified under the TIA
     not later than the effective date of the first Registration Statement
     required by this Agreement and, in connection therewith, cooperate with the
     Trustee and the Holders to effect such changes to the Senior Notes
     Indenture as may be required for such Senior Notes Indenture to be so
     qualified in accordance with the terms of the TIA; and execute and use its
     best efforts to cause the Trustee to execute, all documents that may be
     required to effect such changes and all other forms and documents required
     to be filed with the Commission to enable such Senior Notes Indenture to be
     so qualified in a timely manner; and

          (xviii) provide promptly to each Holder, upon request, each document
     filed with the Commission pursuant to the requirements of Section 13 or
     15(d) of the Exchange Act.


                                       10

     (d) Restrictions on Holders. Each Holder agrees by acquisition of a
Transfer Restricted Security that, upon receipt of the notice referred to in
Section 6(c)(iii)(C) or any notice from the Authority of the existence of any
fact of the kind described in Section 6(c)(iii)(D) hereof (in each case, a
"Suspension Notice"), such Holder will forthwith discontinue disposition of
Transfer Restricted Securities pursuant to the applicable Registration Statement
until (i) such Holder has received copies of the supplemented or amended
Prospectus contemplated by Section 6(c)(iv) hereof, or (ii) such Holder is
advised in writing by the Authority that the use of the Prospectus may be
resumed, and has received copies of any additional or supplemental filings that
are incorporated by reference in the Prospectus (in each case, the
"Recommencement Date"). Each Holder receiving a Suspension Notice hereby agrees
that it will either (i) destroy any Prospectuses, other than permanent file
copies, then in such Holder's possession which have been replaced by the
Authority with more recently dated Prospectuses or (ii) deliver to the Authority
(at the Authority's expense) all copies, other than permanent file copies, then
in such Holder's possession of the Prospectus covering such Transfer Restricted
Securities that was current at the time of receipt of the Suspension Notice. The
time period regarding the effectiveness of such Registration Statement set forth
in Section 3 or 4 hereof, as applicable, shall be extended by a number of days
equal to the number of days in the period from and including the date of
delivery of the Suspension Notice to the date of delivery of the Recommencement
Date.

     (e) Underwritten Offerings. No Holder may participate in any underwritten
Shelf Registration Statement hereunder unless such Holder (i) agrees to sell
such Holder's Transfer Restricted Securities on the basis provided in any
underwriting arrangements entered into in connection therewith and (ii)
completes and executes all questionnaires, powers of attorney, indemnities,
underwriting agreements and other documents reasonably required under the terms
of such underwriting arrangements.

SECTION 7. REGISTRATION EXPENSES

     (a) All expenses incident to the Authority's performance of or compliance
with this Agreement will be borne by the Authority, regardless of whether a
Registration Statement becomes effective, including without limitation: (i) all
registration and filing fees and expenses; (ii) all fees and expenses of
compliance with federal securities and state Blue Sky or securities laws; (iii)
all expenses of printing (including printing certificates for the Senior
Exchange Notes to be issued in the Exchange Offer and printing of Prospectuses),
messenger and delivery services and telephone; (iv) all fees and disbursements
of counsel for the Authority and the Holders of Transfer Restricted Securities;
(v) all application and filing fees in connection with listing the Senior

such performance).

     The Authority will, in any event, bear its internal expenses (including,
without limitation, all salaries and expenses of its officers and employees
performing legal or accounting duties), the expenses of any annual audit and the
fees and expenses of any person, including special experts, retained by the
Authority.

     (b) In connection with any Registration Statement required by this
Agreement (including, without limitation, the Exchange Offer Registration
Statement and the Shelf Registration Statement), the Authority will reimburse
the Initial Purchasers and the Holders of Transfer Restricted Securities who are
tendering Initial Senior Notes into the Exchange Offer and/or selling or
reselling Initial Senior Notes or Senior Exchange Notes pursuant to the "Plan of
Distribution" contained in the Exchange Offer Registration Statement or the
Shelf Registration Statement, as applicable, for the reasonable fees and
disbursements of not more than one counsel, as may be chosen by the Holders of a
majority in principal amount of the Transfer Restricted Securities for whose
benefit such Registration Statement is being prepared. Notwithstanding the
foregoing, the Holders of any Initial Senior Notes or Exchange Senior Notes
being registered on the Shelf Registration Statement shall pay all agency or
brokerage fees and commissions and


                                       11
<PAGE>
 
underwriting discounts and commissions attributable to the sale of such Initial
Senior Notes or Exchange Senior Notes and the fees and disbursements of any
counsel retained by such Holders other than counsel referred to above.

SECTION 8. INDEMNIFICATION

     (a) The Authority agrees to indemnify and hold harmless each Holder, its
directors, officers and each person, if any, who controls such Holder (within
the meaning of Section 15 of the Act or Section 20 of the Exchange Act), from
and against any and all losses, claims, damages, liabilities, judgments,
(including without limitation, any legal or other expenses incurred in
connection with investigating or defending any matter, including any action that
could give rise to any such losses, claims, damages, liabilities or judgments)
caused by any untrue statement or alleged untrue statement of a material fact
contained in any Registration Statement, preliminary prospectus or Prospectus
(or any amendment or supplement thereto) provided by the Authority to any Holder
or any prospective purchaser of Senior Exchange Notes or registered Initial
Senior Notes, or caused by any omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading, except insofar as such losses, claims, damages,
liabilities or judgments are caused by an untrue statement or omission or
alleged untrue statement or omission that is based upon information relating to
any of the Holders furnished in writing to the Authority by any of the Holders.

     (b) Each Holder of Transfer Restricted Securities agrees, severally and not
jointly, to indemnify and hold harmless the Authority and its directors and
officers, and each person, if any, who controls (within the meaning of Section
15 of the Act or Section 20 of the Exchange Act) the Authority to the same
extent as the foregoing indemnity from the Authority set forth in section (a)
above, but only with reference to information relating to such Holder furnished
in writing to the Authority by such Holder expressly for use in any Registration
Statement. In no event shall any Holder, its directors, officers or any person
who controls such Holder be liable or responsible for any amount in excess of
the amount by which the total amount received by such Holder with respect to its
sale of Transfer Restricted Securities pursuant to a Registration Statement
exceeds (i) the amount paid by such Holder for such Transfer Restricted
Securities and (ii) the amount of any damages that such Holder, its directors,
officers or any person who controls such Holder has otherwise been required to
pay by reason of such untrue or alleged untrue statement or omission or alleged
omission.

     (c) In case any action shall be commenced involving any person in respect
of which indemnity may be sought pursuant to Section 8(a) or 8(b) (the
"indemnified party"), the indemnified party shall promptly notify the person
against whom such indemnity may be sought (the "indemnifying person") in writing
and the indemnifying party shall assume the defense of such action, including
the employment of counsel reasonably satisfactory to the indemnified party and
the payment of all fees and expenses of such counsel, as incurred (except that
in the case of any action in respect of which indemnity may be sought pursuant
to both Sections 8(a) and 8(b), a Holder shall not be required to assume the
defense of such action pursuant to this Section 8(c), but may employ separate
counsel and participate in the defense thereof, but the fees and expenses of
such counsel, except as provided below, shall be at the expense of the Holder).
Any indemnified party shall have the right to employ separate counsel in any
such action and participate in the defense thereof, but the fees and expenses of
such counsel shall be at the expense of the indemnified party unless (i) the
employment of such counsel shall have been specifically authorized in writing by
the indemnifying party, (ii) the indemnifying party shall have failed to assume
the defense of such action or employ counsel reasonably satisfactory to the
indemnified party or (iii) the named parties to any such action (including any
impleaded parties) include both the indemnified party and the indemnifying
party, and the indemnified party shall have been advised by such counsel that
there may be one or more legal defenses available to it which are different from
or additional to those available to the indemnifying party (in which case the
indemnifying party shall not have the right to assume the defense of such action
on behalf of the indemnified party). In any such case, the indemnifying party
shall not, in connection with any one action or separate but substantially
similar or related actions in the same jurisdiction arising out of the same
general


                                       12
<PAGE>
 
allegations or circumstances, be liable for the fees and expenses of more than
one separate firm of attorneys (in addition to any local counsel) for all
indemnified parties and all such fees and expenses shall be reimbursed as they
are incurred. Such firm shall be designated in writing by a majority of the
Holders, in the case of the parties indemnified pursuant to Section 8(a), and by
the Authority, in the case of parties indemnified pursuant to Section 8(b). The
indemnifying party shall indemnify and hold harmless the indemnified party from
and against any and all losses, claims, damages, liabilities and judgments by
reason of any settlement of any action (i) effected with its written consent or
(ii) effected without its written consent if the settlement is entered into more
than 20 Business Days after the indemnifying party shall have received a request
from the indemnified party for reimbursement for the fees and expenses of
counsel (in any case where such fees and expenses are at the expense of the
indemnifying party) and, prior to the date of such settlement, the indemnifying
party shall have failed to comply with such reimbursement request. No
indemnifying party shall, without the prior written consent of the indemnified
party, effect any settlement or compromise of, or consent to the entry of
judgment with respect to, any pending or threatened action in respect of which
the indemnified party is or could have been a party and indemnity or
contribution may be or could have been sought hereunder by the indemnified
party, unless such settlement, compromise or judgment (i) includes an
unconditional release of the indemnified party from all liability on claims that
are or could have been the subject matter of such action and (ii) does not
include a statement as to or an admission of fault, culpability or a failure to
act, by or on behalf of the indemnified party.

     (d) To the extent that the indemnification provided for in this Section 8
is unavailable to an indemnified party in respect of any losses, claims,
damages, liabilities or judgments referred to therein, then each indemnifying
party, in lieu of indemnifying such indemnified party, shall contribute to the
amount paid or payable by such indemnified party as a result of such losses,
claims, damages, liabilities or judgments (i) in such proportion as is
appropriate to reflect the relative benefits received by the Authority, on the
one hand, and the Holders, on the other hand, from their sale of Transfer
Restricted Securities or (ii) if the allocation provided by clause 8(d)(i) is
not permitted by applicable law, in such proportion as is appropriate to reflect
not only the relative benefits referred to in clause 8(d)(i) above but also the
relative fault of the Authority, on the one hand, and of the Holder, on the
other hand, in connection with the statements or omissions which resulted in
such losses, claims, damages, liabilities or judgments, as well as any other
relevant equitable considerations. The relative fault of the Authority, on the
one hand, and of the Holder, on the other hand, shall be determined by reference
to, among other things, whether the untrue or alleged untrue statement of a
material fact or the omission or alleged omission to state a material fact
relates to information supplied by the Authority, on the one hand, or by the
Holder, on the other hand, and the parties' relative intent, knowledge, access
to information and opportunity to correct or prevent such statement or omission.
The amount paid or payable by a party as a result of the losses, claims,
damages, liabilities and judgments referred to above shall be deemed to include,
subject to the limitations set forth in the second paragraph of Section 8(a),
any legal or other fees or expenses reasonably incurred by such party in
connection with investigating or defending any action or claim.

     The Authority and each Holder agree that it would not be just and equitable
if contribution pursuant to this Section 8(d) were determined by pro rata
allocation (even if the Holders were treated as one entity for such purpose) or
by any other method of allocation which does not take account of the equitable
considerations referred to in the immediately preceding paragraph. The amount
paid or payable by an indemnified party as a result of the losses, claims,
damages, liabilities or judgments referred to in the immediately preceding
paragraph shall be deemed to include, subject to the limitations set forth
above, any legal or other expenses reasonably incurred by such indemnified party
in connection with investigating or defending any matter, including any action
that could have given rise to such losses, claims, damages, liabilities or
judgments. Notwithstanding the provisions of this Section 8, no Holder, its
directors, its officers or any person, if any, who controls such Holder shall be
required to contribute, in the aggregate, any amount in excess of the amount by
which the total received by such Holder with respect to the sale of Transfer
Restricted Securities pursuant to a Registration Statement exceeds (i) the
amount paid by such Holder for such Transfer Restricted Securities and (ii) the
amount of any damages which such Holder has


                                       13
<PAGE>
 
otherwise been required to pay by reason of such untrue or alleged untrue
statement or omission or alleged omission. No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Act) shall be
entitled to contribution from any person who was not guilty of such fraudulent
misrepresentation. The Holders' obligations to contribute pursuant to this
Section 8(d) are several in proportion to the respective principal amount of
Transfer Restricted Securities held by each Holder hereunder and not joint.

SECTION 9. RULE 144A and RULE 144

     The Authority agrees with each Holder, for so long as any Transfer
Restricted Securities remain outstanding and during any period in which the
Authority (i) is not subject to Section 13 or 15(d) of the Exchange Act, to make
available, upon request of any Holder, to such Holder or beneficial owner of
Transfer Restricted Securities in connection with any sale thereof and any
prospective purchaser of such Transfer Restricted Securities designated by such
Holder or beneficial owner, the information required by Rule 144A(d)(4) under
the Act in order to permit resales of such Transfer Restricted Securities
pursuant to Rule 144A, and (ii) is subject to Section 13 or 15 (d) of the
Exchange Act, to make all filings required thereby in a timely manner in order
to permit resales of such Transfer Restricted Securities pursuant to Rule 144.

SECTION 10. CONSENT TO SUIT

     The Authority waives its sovereign immunity from unconsented suit, whether
such suit be brought in law or in equity, or in administrative proceedings or
proceedings in arbitration, to permit the commencement, maintenance, and
enforcement of any action, by any person with standing to maintain an action, to
interpret or enforce the terms of this Agreement, and to enforce and execute any
judgment resulting therefrom against the Authority or the assets of the
Authority. Notwithstanding any other provision of law or canon of construction,
the Authority intends this waiver to be interpreted liberally to permit the full
litigation of disputes arising under or out of this Agreement. Without limiting
the generality of the foregoing, the Authority waives its immunity from
unconsented suit to permit the maintenance of the following actions:

          (i) Courts. The Authority waives its immunity from unconsented suit to
     permit any court of competent jurisdiction to: (i) enforce and interpret
     the terms of this Agreement, and award and enforce the award of damages
     owing as a consequence of a breach thereof, whether such award is the
     product of litigation, administrative proceedings or arbitration; (ii)
     determine whether any consent or approval of the Authority has been
     improperly granted or unreasonably withheld; (iii) enforce any judgment
     prohibiting the Authority from taking any action, or mandating or
     obligating the Authority to take any action, including a judgment
     compelling the Authority to submit to binding arbitration; and (iv)
     adjudicate any claim under the Indian Civil Rights Act of 1968, 25 U.S.C.
     ss. 1302 (or any successor statute).

          (ii) Arbitration. The Authority waives its immunity from unconsented
     suit to permit arbitrators, appointed and acting under the commercial
     arbitration rules of the American Arbitration Association, whenever and to
     the extent any agreement to submit a matter to arbitration is made by the
     Authority, to: (i) enforce and interpret the terms of this Agreement and to
     award and enforce the award of any damages owing as a consequence thereof;
     (ii) determine whether any consent or approval of the Authority has been
     unreasonably withheld; and (iii) enforce any judgment prohibiting the
     Authority from taking any action, or mandating or obligating the Authority
     to take any action, including a judgment compelling the Authority to submit
     to binding arbitration.

SECTION 11. MISCELLANEOUS

     (a) Remedies. The Authority acknowledges and agrees that any failure by the
Authority to comply with its obligations under Sections 3 and 4 hereof may
result in material irreparable injury to the


                                       14
<PAGE>
 
Initial Purchasers or the Holders for which there is no adequate remedy at law,
that it will not be possible to measure damages for such injuries precisely and
that, in the event of any such failure, the Initial Purchasers or any Holder may
obtain such relief as may be required to specifically enforce the Authority's
obligations under Sections 3 and 4 hereof. The Authority further agrees to waive
the defense in any action for specific performance that a remedy at law would be
adequate.

     (b) No Inconsistent Agreements. The Authority will not, on or after the
date of this Agreement, enter into any agreement with respect to its securities
that is inconsistent with the rights granted to the Holders in this Agreement or
otherwise conflicts with the provisions hereof. The rights granted to the
Holders hereunder do not in any way conflict with and are not inconsistent with
the rights granted to the holders of the Authority's securities under any
agreement in effect on the date hereof.

     (c) Amendments and Waivers. The provisions of this Agreement may not be
amended, modified or supplemented, and waivers or consents to or departures from
the provisions hereof may not be given unless (i) in the case of Section 5
hereof and this Section 11(c)(i), the Authority has obtained the written consent
of Holders of all outstanding Transfer Restricted Securities and (ii) in the
case of all other provisions hereof, the Authority has obtained the written
consent of Holders of a majority of the outstanding principal amount of Transfer
Restricted Securities (excluding Transfer Restricted Securities held by the
Authority or its Affiliates). Notwithstanding the foregoing, a waiver or consent
to departure from the provisions hereof that relates exclusively to the rights
of Holders whose Transfer Restricted Securities are being tendered pursuant to
the Exchange Offer, and that does not affect directly or indirectly the rights
of other Holders whose Transfer Restricted Securities are not being tendered
pursuant to such Exchange Offer, may be given by the Holders of a majority of
the outstanding principal amount of Transfer Restricted Securities subject to
such Exchange Offer.

     (d) Third Party Beneficiary. The Holders shall be third party beneficiaries
to the agreements made hereunder between the Authority, on the one hand, and the
Initial Purchasers, on the other hand, and shall have the right to enforce such
agreements directly to the extent they may deem such enforcement necessary or
advisable to protect its rights or the rights of Holders hereunder.

     (e) Notices. All notices and other communications provided for or permitted
hereunder shall be made in writing by hand-delivery, first-class mail

and be binding upon the successors and assigns of each of the parties, including
without limitation and without the need for an express assignment, subsequent
Holders; provided, that nothing herein shall be deemed to permit any assignment,
transfer or other disposition of Transfer Restricted Securities in violation of
the terms hereof or of the Purchase Agreement or the Senior Notes Indenture. If
any transferee of any Holder shall acquire Transfer Restricted Securities in any
manner, whether by operation of law or otherwise, such Transfer Restricted
Securities shall be held subject to all of the terms of this Agreement, and by
taking and holding such Transfer Restricted Securities such person shall be
conclusively deemed to have agreed to be bound by and to perform all of the

with respect to the registration rights granted with respect to the Transfer
Restricted Securities. This Agreement supersedes all prior agreements and
understandings between the parties with respect to such subject matter.

<PAGE>
 
     Capitalized terms used herein shall have the meanings assigned to them in
the Indenture referred to below unless otherwise indicated.

     1. INTEREST.

     (a) The Mohegan Tribal Gaming Authority (the "Authority"), promises to pay
interest on the principal amount of this Senior Note at 8 1/8% per annum from
March 3, 1999 until maturity. The Authority will pay interest and Additional
Interest, if any, semi-annually in arrears on January 1 and July 1 of each year,
or if any such day is not a Business Day, on the next succeeding Business Day
(each an "Interest Payment Date"). Interest on the Senior Notes will accrue from
the most recent date to which interest has been paid or, if no interest has been
paid, from the date of issuance; provided that if there is no existing Default
in the payment of interest, and if this Senior Note is authenticated between a
record date referred to on the face hereof and the next succeeding Interest
Payment Date, interest shall accrue from such next succeeding Interest Payment
Date; provided, further, that the first Interest Payment Date shall be July 1,
1999. The Authority shall pay interest (including post-petition interest in any
proceeding under any Bankruptcy Law) on overdue principal and premium, if any,
from time to time on demand at a rate that is 1% per annum in excess of the rate
then in effect; it shall pay interest (including post-petition interest in any
proceeding under any Bankruptcy Law) on overdue installments of interest and
Additional Interest, if any, (without regard to any applicable grace periods)
from time to time on demand at the same rate to the extent lawful. Interest will
be computed on the basis of a 360-day year of twelve 30-day months.

     (b) The Holder of this Senior Note is entitled to the benefits of the
Senior Registration Rights Agreement dated as of the date hereof, among the
Authority and the Initial Purchasers named therein (the "Senior Registration
Rights Agreement"). If (i) the Authority fails to file any of the Registration
Statements required by the Registration Rights Agreements on or before the date
specified for such filing, (ii) any of such Registration Statements is not
declared effective by the Commission on or prior to the date specified for such
effectiveness (the "Effectiveness Target Date"), (iii) the Authority fails to
consummate the Exchange Offer within 30 business days of the Effectiveness
Target Date with respect to the Exchange Offer Registration Statement, or (iv)
the Shelf Registration Statement or the Exchange Offer Registration Statement is
declared effective but thereafter ceases to be effective or usable in connection
with resales of Transfer Restricted Securities during the periods specified in
the Registration Rights Agreement (each such event referred to in clauses (i)
through (iv) above a "Registration Default"), then the Authority will pay
Additional Interest to each Holder of Senior Notes, with respect to the first
90-day period immediately following the occurrence of the first Registration
Default in an amount equal to 25 basis points per 90-day period of the principal
amount of Senior Notes held by such Holder. The amount of the Additional
Interest will increase by an additional 25 basis points with respect to each
subsequent 90-day period until all Registration Defaults have been cured, up to
a maximum amount of Additional Interest of 1% per annum of the principal amount
of Senior Notes.

     (A) Except as expressly provided in this paragraph 1(b), Additional
Interest shall be treated as interest and any date on which Additional Interest
is due and payable shall be treated as an Interest Payment Date for all purposes
under this Senior Note and the Indenture.

     (B) In the event that the Authority is required to pay Additional Interest
pursuant to this paragraph 1(b), the Authority shall notify the Trustee in
writing at least 15 days
<PAGE>
 
prior to the first Interest Payment Date upon which such Additional Interest is
due; provided that, in the event that the obligation to pay such Additional
Interest occurs less than 15 days prior to such Additional Interest Date, such
notice shall be provided by the Authority to the Trustee as soon as reasonably
practicable prior to such Interest Payment Date.

     2. METHOD OF PAYMENT. The Authority will pay interest on the Senior Notes
(except defaulted interest) and Additional Interest, if any, to the Persons who
are registered Holders of Senior Notes at the close of business on the December
15 or June 15 next preceding the Interest Payment Date, even if such Senior
Notes are canceled after such record date and on or before such Interest Payment
Date, except as provided in Section 2.12 of the Indenture with respect to
defaulted interest. The Senior Notes will be payable as to principal, premium
and Additional Interest, if any, and interest at the office or agency of the
Authority maintained for such purpose within or without the City and State of
New York, or, at the option of the Authority, payment of interest and Additional
Interest may be made by check mailed to the Holders at their addresses set forth
in the register of Holders, and provided that payment by wire transfer of
immediately available funds will be required with respect to principal of and
interest, premium and Additional Interest on, all Global Senior Notes and all
other Senior Notes the Holders of which shall hold at least $1.0 million in
principal amount of Senior Notes and have provided wire transfer instructions to
the Authority or the Paying Agent. Such payment shall be in such coin or
currency of the United States of America as at the time of payment is legal
tender for payment of public and private debts.

     3. PAYING AGENT AND REGISTRAR. Initially, First Union National Bank, the
Trustee under the Indenture, will act as Paying Agent and Registrar. The
Authority may change any Paying Agent or Registrar without notice to any Holder.
The Authority or any of its Subsidiaries may act in any such capacity.

     4. INDENTURE. The Authority issued the Senior Notes under an Indenture
dated as of March 3, 1999 ("Indenture") between the Authority and the Trustee.
The terms of the Senior Notes include those stated in the Indenture and those
made part of the Indenture by reference to the Trust Indenture Act of 1939, as
amended (15 U.S. Code ss.ss. 77aaa-77bbbb). The Senior Notes are subject to all
such terms, and Holders are referred to the Indenture and such Act for a
statement of such terms. To the extent any provision of this Senior Note
conflicts with the express provisions of the Indenture, the provisions of the
indenture shall govern and be controlling.

     5. OPTIONAL REDEMPTION.

     (a) The Authority may redeem all or a part of these Senior Notes upon not
less than 30 nor more than 60 days' notice, at a redemption price (expressed as
percentages of principal amount) equal to 100% of the principal amount thereof
plus the Applicable Premium, if any, plus accrued and unpaid interest thereon,
if any, to the applicable redemption date.

     (b) Notwithstanding any other provisions of Article 3 of the Indenture, if
any Gaming Regulatory Authority requires that a Holder or beneficial owner of
the Notes be licensed, qualified or found suitable under any applicable gaming
laws in order to maintain any gaming license or franchise of the Authority under
any applicable gaming laws, and the Holder or beneficial owner fails to apply
for a license, qualification or finding of suitability within 30 days after
being requested to do so by such Gaming Regulatory Authority (or such lesser
period that
<PAGE>
 
may be required by such Gaming Regulatory Authority) or if such Holder or
beneficial owner is not so licensed, qualified or found suitable, the Authority
has the right, at its option, (i) to require such Holder or beneficial owner to
dispose of such Holder's or beneficial owner's Senior Notes within 30 days of
receipt of such notice of such finding by the applicable Gaming Regulatory
Authority (or such earlier date as may be required by the applicable Gaming
Regulatory Authority) or (ii) to call for redemption of the Senior Notes of such
Holder or beneficial owner at a redemption price equal to the lesser of (1) the
principal amount thereof or (2) the price at which such Holder or beneficial
owner acquired the Senior Notes or (3) the current market price of the Senior
Notes, together with, in either case, accrued and unpaid interest and Additional
Interest, if any, to the earlier of the date of redemption or the date of the
finding of unsuitability by such Gaming Regulatory Authority, which may be less
than 30 days following the notice of redemption if so ordered by such Gaming
Regulatory Authority. The Authority shall not be required to pay or reimburse
any Holder or beneficial owner of Senior Notes who is required to apply for any
such license, qualification or finding of suitability for the costs of the
licensure or investigation for such qualification or finding of suitability.
Such expenses shall be the obligation of such Holder or beneficial owner.

     6. MANDATORY REDEMPTION.

     Except as set forth in paragraph 7 below, the Authority shall not be
required to make mandatory redemption payments with respect to the Senior Notes.

     7. REPURCHASE AT OPTION OF HOLDER.

     (a) If there is a Change of Control, the Authority shall be required to
make an offer (a "Change of Control Offer") to repurchase all or any part (equal
to $1,000 or an integral multiple thereof) of each Holder's Senior Notes at a
purchase price equal to 101% of the aggregate principal amount thereof plus
accrued and unpaid interest and Additional Interest thereon, if any, to the date
of purchase (the "Change of Control Payment"). Within 20 Business Days following
any Change of Control, the Authority shall mail a notice to each Holder setting
forth the procedures governing the Change of Control Offer as required by the
Indenture.

     (b) If the Authority or a Subsidiary consummates any Asset Sales, within
five Business Days of each date on which the aggregate amount of Excess Proceeds
exceeds $15.0 million, the Authority shall commence an offer to all Holders of
Senior Notes (as "Asset Sale Offer") pursuant to Section 3.10 of the Indenture
to purchase the maximum principal amount of Senior Notes that may be purchased
out of the Excess Proceeds at an offer price in cash in an amount equal to 100%
of the principal amount thereof plus accrued and unpaid interest and Additional
Interest thereon, if any, to the date fixed for the closing of such offer, in
accordance with the procedures set forth in the Indenture. To the extent that
the aggregate amount of Senior Notes tendered pursuant to an Asset Sale Offer is
less than the Excess Proceeds, the Authority (or such Subsidiary) may use such
deficiency for any purpose not otherwise permitted by the Indenture. If the
aggregate principal amount of Senior Notes surrendered by Holders thereof
exceeds the amount of Excess Proceeds, the Trustee shall select the Senior Notes
to be purchased on a pro rata basis. Holders of Senior Notes that are the
subject of an offer to purchase will receive an Asset Sale Offer from the
Authority prior to any related purchase date and may elect to have such Senior
Notes purchased by completing the form entitled "Option of Holder to Elect
Purchase" on the reverse of the Senior Notes.

     8. NOTICE OF REDEMPTION. Notice of redemption will be mailed at least 30
days but not more than 60 days before the redemption date to each Holder whose
Senior Notes are to be redeemed at its registered address. Senior Notes in
denominations larger than $1,000 may be redeemed in part but only in whole
multiples of $1,000, unless all of the Senior Notes held by a Holder are to be
redeemed. On and after the redemption date interest ceases to accrue on Senior
Notes or portions thereof called for redemption.

     9. DENOMINATIONS, TRANSFER, EXCHANGE. The Senior Notes are in registered
form without coupons in denominations of $1,000 and integral multiples of
$1,000. The transfer of Senior Notes may be registered and Senior Notes may be
exchanged as provided in the Indenture. The Registrar and the Trustee may
require a Holder, among other things, to furnish appropriate endorsements and
transfer documents and the Authority may require a Holder to pay any taxes and
fees required by law or permitted by the Indenture. The Authority need not
exchange or register the transfer of any Senior Note or portion of a Senior Note
selected for redemption, except for the unredeemed portion of any Senior Note
being redeemed in part. Also, the Authority need not exchange or register the
transfer of any Senior Notes for a period of 15 days before a selection of
Senior Notes to be redeemed or during the period between a record date and the
corresponding Interest Payment Date.

     10. PERSONS DEEMED OWNERS. The registered Holder of a Senior Note may be
treated as its owner for all purposes.

     11. AMENDMENT, SUPPLEMENT AND WAIVER. Subject to certain exceptions, the
Indenture, the Senior Subsidiary Guarantees or the Senior Notes may be amended
or supplemented with the consent of the Holders of at least a majority in
principal amount of the then outstanding Senior Notes voting as a single class,
and any existing default or compliance with any provision of the Indenture, the
Senior Subsidiary Guarantees or the Senior Notes may be waived with the consent
of the Holders of a majority in principal amount of the then outstanding Senior
Notes voting as a single class. Without the consent of any Holder of a Senior
Note, the Indenture, the Senior Subsidiary Guarantees or the Senior Notes may be
amended or supplemented to cure any ambiguity, defect or inconsistency, to
provide for uncertificated Senior Notes in addition to or in place of
certificated Senior Notes, to provide for the assumption of the Authority's or
Subsidiary Guarantor's obligations to Holders of the Senior Notes by a successor
to the Authority or such Subsidiary Guarantor, to make any change that would
provide any additional rights or benefits to the Holders of the Senior Notes or
that does not adversely affect the legal rights under the Indenture of any such
Holder, to comply with the requirements of the SEC in order to effect or
maintain the qualification of the Indenture under the Trust Indenture Act, or to
allow any Subsidiary Guarantor to execute a supplemental indenture to the
Indenture and/or a Senior Subsidiary Guarantee with respect to the Senior Notes
provided that the Authority has obtained any required government approval to
ensure the enforceability of the Senior Notes and the Indenture.

     12. DEFAULTS AND REMEDIES. Events of Default include: (i) default for 30
days in the payment when due of interest or Additional Interest on the Senior
Notes; (ii) default in payment when due of principal of or premium, if any, on
the Senior Notes when the same becomes due and payable at maturity, upon
redemption (including in connection with an offer to purchase) or otherwise;
(iii) failure by the Authority or any of its Restricted Subsidiaries to comply
with Section 4.10 or 5.01 of the Indenture; (iv) failure by the Authority or any
of its Restricted Subsidiaries to observe or perform (A) any covenant described
in Section 4.07 or 4.09
<PAGE>
 
of the Indenture for 30 days after notice to the Authority by the Trustee or the
Holders of at least 25% in aggregate principal amount of the Senior Notes then
outstanding voting as a single class or (B) any other covenant, representation,
warranty or other agreement in the Indenture or the Senior Notes for 60 days
after notice to the Authority by the Trustee or the Holders of at least 25% in
aggregate principal amount of the Senior Notes then outstanding voting as a
single class; (v) default under certain other agreements relating to
Indebtedness of the Authority or any of its Restricted Subsidiaries which
default results in the acceleration of such Indebtedness prior to its express
maturity; (vi) certain final judgments for the payment of money that remain
undischarged for a period of 60 days; (vii) certain events of bankruptcy or
insolvency with respect to the Authority or any of its Restricted Subsidiaries;
(viii) revocation, termination, suspension or other cessation of effectiveness
of any Gaming License which results in the cessation or suspension of gaming
operations for a period of more than 90 consecutive days at the Resort; (ix)
cessation of gaming operations for a period of more than 90 consecutive days at
the Resort (other than as a result of a casualty loss); (x) the Lease ceases to
be in full force and effect; (xi) except as permitted by the Indenture, any
Senior Subsidiary Guarantee shall be held in any judicial proceeding to be
unenforceable or invalid or shall cease for any reason to be in full force and
effect or any Subsidiary Guarantor or any Person acting on its behalf shall deny
or disaffirm its obligations under such Subsidiary Guarantor's Senior Subsidiary
Guarantee; and (xii) failure by the Tribe to comply with the provisions of
Article 10 of the Indenture for 30 days after notice to the Authority and the
Tribe by the Trustee or the Holders of at least 25% in aggregate principal
amount of the Senior Notes then outstanding voting as a single class. If any
Event of Default occurs and is continuing, the Trustee or the Holders of at
least 25% in principal amount of the then outstanding Senior Notes may declare
all the Senior Notes to be due and payable. Notwithstanding the foregoing, in
the case of an Event of Default arising from certain events of bankruptcy or
insolvency, all outstanding Senior Notes will become due and payable without
further action or notice. Holders may not enforce the Indenture or the Senior
Notes except as provided in the Indenture. Subject to certain limitations,
Holders of a majority in principal amount of the then outstanding Senior Notes
may direct the Trustee in its exercise of any trust or power. The Trustee may
withhold from Holders of the Senior Notes notice of any continuing Default or
Event of Default (except a Default or Event of Default relating to the payment
of principal or interest) if it determines that withholding notice is in their
interest. The Holders of a majority in aggregate principal amount of the Senior
Notes then outstanding by notice to the Trustee may on behalf of the Holders of
all of the Senior Notes waive any existing Default or Event of Default and its
consequences under the Indenture except a continuing Default or Event of Default
in the payment of interest on, or the principal of, the Senior Notes. The
Authority is required to deliver to the Trustee annually a statement regarding
compliance with the Indenture, and the Authority is required upon becoming aware
of any Default or Event of Default, to deliver to the Trustee a statement
specifying such Default or Event of Default.

     13. TRUSTEE DEALINGS WITH AUTHORITY. The Trustee, in its individual or any
other capacity, may make loans to, accept deposits from, and perform services
for the Authority or its Affiliates, and may otherwise deal with the Authority
or its Affiliates, as if it were not the Trustee.

     14. NO RECOURSE AGAINST OTHERS. A controlling person, director, officer,
employee or holder of an Ownership Interest of the Authority, as such, shall not
have any liability for any obligations of the Authority under the Senior Notes
or the Indenture or for any claim based on, in respect of, or by reason of, such
obligations or their creation. Each Holder by
<PAGE>
 
accepting a Senior Note waives and releases all such liability. The waiver and
release are part of the consideration for the issuance of the Senior Notes.

     15. AUTHENTICATION. This Senior Note shall not be valid until authenticated
by the manual signature of the Trustee or an authenticating agent.

     16. ABBREVIATIONS. Customary abbreviations may be used in the name of a
Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (=
tenants by the entireties), JT TEN (= joint tenants with right of survivorship
and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts
to Minors Act).

     17. ADDITIONAL RIGHTS OF HOLDERS OF RESTRICTED GLOBAL SENIOR NOTES AND
RESTRICTED DEFINITIVE SENIOR NOTES. In addition to the rights provided to
Holders of Senior Notes under the Indenture, Holders of Restricted Global Senior
Notes and Restricted Definitive Senior Notes shall have all the rights set forth
in the Senior Registration Rights Agreement dated as of March 3, 1999, between
the Authority and the parties named on the signature pages thereof (the "Senior
Registration Rights Agreement").

     18. CUSIP NUMBERS. Pursuant to a recommendation promulgated by the
Committee on Uniform Security Identification Procedures, the Authority has
caused CUSIP numbers to be printed on the Senior Notes and the Trustee may use
CUSIP numbers in notices of redemption as a convenience to Holders. No
representation is made as to the accuracy of such numbers either as printed on
the Senior Notes or as contained in any notice of redemption and reliance may be
placed only on the other identification numbers placed thereon.

     The Authority will furnish to any Holder upon written request and without
charge a copy of the Indenture and/or the Senior Registration Rights Agreement.

the Indenture referred to below unless otherwise indicated.

     1. INTEREST.

     (a) The Mohegan Tribal Gaming Authority (the "Authority"), promises to pay
interest on the principal amount of this Senior Note at 8 1/8% per annum from
March 3, 1999 until maturity. The Authority will pay interest and Additional
Interest, if any, semi-annually in arrears on January 1 and July 1 of each year,
or if any such day is not a Business Day, on the next succeeding Business Day
(each an "Interest Payment Date"). Interest on the Senior Notes will accrue from
the most recent date to which interest has been paid or, if no interest has been
paid, from the date of issuance; provided that if there is no existing Default
in the payment of interest, and if this Senior Note is authenticated between a
record date referred to on the face hereof and the next succeeding Interest
Payment Date, interest shall accrue from such next succeeding Interest Payment
Date; provided, further, that the first Interest Payment Date shall be July 1,
1999. The Authority shall pay interest (including post-petition interest in any
proceeding under any Bankruptcy Law) on overdue principal and premium, if any,
from time to time on demand at a rate that is 1% per annum in excess of the rate
then in effect; it shall pay interest (including post-petition interest in any
proceeding under any Bankruptcy Law) on overdue installments of interest and
Additional Interest, if any, (without regard to any applicable grace periods)
from time to time on demand at the same rate to the extent lawful. Interest will
be computed on the basis of a 360-day year of twelve 30-day months.

     (b) The Holder of this Senior Note is entitled to the benefits of the
Senior Registration Rights Agreement dated as of the date hereof, among the
Authority and the Initial Purchasers named therein (the "Senior Registration
Rights Agreement"). If (i) the Authority fails to file any of the Registration
Statements required by the Registration Rights Agreements on or before the date
specified for such filing, (ii) any of such Registration Statements is not
declared effective by the Commission on or prior to the date specified for such
effectiveness (the "Effectiveness Target Date"), (iii) the Authority fails to
consummate the Exchange Offer within 30 business days of the Effectiveness
Target Date with respect to the Exchange Offer Registration Statement, or (iv)
the Shelf Registration Statement or the Exchange Offer Registration Statement is
declared effective but thereafter ceases to be effective or usable in connection
with resales of Transfer Restricted Securities during the periods specified in
the Registration Rights Agreement (each such event referred to in clauses (i)
through (iv) above a "Registration Default"), then the Authority will pay
Additional Interest to each Holder of Senior
<PAGE>
 
Notes, with respect to the first 90-day period immediately following the
occurrence of the first Registration Default in an amount equal to 25 basis
points per 90-day period of the principal amount of Senior Notes held by such
Holder. The amount of the Additional Interest will increase by an additional 25
basis points with respect to each subsequent 90-day period until all
Registration Defaults have been cured, up to a maximum amount of Additional
Interest of 1% per annum of the principal amount of Senior Notes.

     (A) Except as expressly provided in this paragraph 1(b), Additional
Interest shall be treated as interest and any date on which Additional Interest
is due and payable shall be treated as an Interest Payment Date for all purposes
under this Senior Note and the Indenture.

     (B) In the event that the Authority is required to pay Additional Interest
pursuant to this paragraph 1(b), the Authority shall notify the Trustee in
writing at least 15 days prior to the first Interest Payment Date upon which
such Additional Interest is due; provided that, in the event that the obligation
to pay such Additional Interest occurs less than 15 days prior to such
Additional Interest Date, such notice shall be provided by the Authority to the
Trustee as soon as reasonably practicable prior to such Interest Payment Date.

     2. METHOD OF PAYMENT. The Authority will pay interest on the Senior Notes
(except defaulted interest) and Additional Interest, if any, to the Persons who
are registered Holders of Senior Notes at the close of business on the December
15 or June 15 next preceding the Interest Payment Date, even if such Senior
Notes are canceled after such record date and on or before such Interest Payment
Date, except as provided in Section 2.12 of the Indenture with respect to
defaulted interest. The Senior Notes will be payable as to principal, premium
and Additional Interest, if any, and interest at the office or agency of the
Authority maintained for such purpose within or without the City and State of
New York, or, at the option of the Authority, payment of interest and Additional
Interest may be made by check mailed to the Holders at their addresses set forth
in the register of Holders, and provided that payment by wire transfer of
immediately available funds will be required with respect to principal of and
interest, premium and Additional Interest on, all Global Senior Notes and all
other Senior Notes the Holders of which shall hold at least $1.0 million in
principal amount of Senior Notes and have provided wire transfer instructions to
the Authority or the Paying Agent. Such payment shall be in such coin or
currency of the United States of America as at the time of payment is legal
tender for payment of public and private debts.

     3. PAYING AGENT AND REGISTRAR. Initially, First Union National Bank, the
Trustee under the Indenture, will act as Paying Agent and Registrar. The
Authority may change any Paying Agent or Registrar without notice to any Holder.
The Authority or any of its Subsidiaries may act in any such capacity.

     4. INDENTURE. The Authority issued the Senior Notes under an Indenture
dated as of March 3, 1999 ("Indenture") between the Authority and the Trustee.
The terms of the Senior Notes include those stated in the Indenture and those
made part of the Indenture by reference to the Trust Indenture Act of 1939, as
amended (15 U.S. Code ss.ss. 77aaa-77bbbb). The Senior Notes are subject to all
such terms, and Holders are referred to the Indenture and such Act for a
statement of such terms. To the extent any provision of this Senior Note
conflicts with the express provisions of the Indenture, the provisions of the
indenture shall govern and be controlling.
<PAGE>
 
     5. OPTIONAL REDEMPTION.

     (a) The Authority may redeem all or a part of these Senior Notes upon not
less than 30 nor more than 60 days' notice, at a redemption price (expressed as
percentages of principal amount) equal to 100% of the principal amount thereof
plus the Applicable Premium, if any, plus accrued and unpaid interest thereon,
if any, to the applicable redemption date.

     (b) Notwithstanding any other provisions of Article 3 of the Indenture, if
any Gaming Regulatory Authority requires that a Holder or beneficial owner of
the Notes be licensed, qualified or found suitable under any applicable gaming
laws in order to maintain any gaming license or franchise of the Authority under
any applicable gaming laws, and the Holder or beneficial owner fails to apply
for a license, qualification or finding of suitability within 30 days after
being requested to do so by such Gaming Regulatory Authority (or such lesser
period that may be required by such Gaming Regulatory Authority) or if such
Holder or beneficial owner is not so licensed, qualified or found suitable, the
Authority has the right, at its option, (i) to require such Holder or beneficial
owner to dispose of such Holder's or beneficial owner's Senior Notes within 30
days of receipt of such notice of such finding by the applicable Gaming
Regulatory Authority (or such earlier date as may be required by the applicable
Gaming Regulatory Authority) or (ii) to call for redemption of the Senior Notes
of such Holder or beneficial owner at a redemption price equal to the lesser of
(1) the principal amount thereof or (2) the price at which such Holder or
beneficial owner acquired the Senior Notes or (3) the current market price of
the Senior Notes, together with, in either case, accrued and unpaid interest and
Additional Interest, if any, to the earlier of the date of redemption or the
date of the finding of unsuitability by such Gaming Regulatory Authority, which
may be less than 30 days following the notice of redemption if so ordered by
such Gaming Regulatory Authority. The Authority shall not be required to pay or
reimburse any Holder or beneficial owner of Senior Notes who is required to
apply for any such license, qualification or finding of suitability for the
costs of the licensure or investigation for such qualification or finding of
suitability. Such expenses shall be the obligation of such Holder or beneficial
owner.

     6. MANDATORY REDEMPTION.

     Except as set forth in paragraph 7 below, the Authority shall not be
required to make mandatory redemption payments with respect to the Senior Notes.

     7. REPURCHASE AT OPTION OF HOLDER.

     (a) If there is a Change of Control, the Authority shall be required to
make an offer (a "Change of Control Offer") to repurchase all or any part (equal
to $1,000 or an integral multiple thereof) of each Holder's Senior Notes at a
purchase price equal to 101% of the aggregate principal amount thereof plus
accrued and unpaid interest and Additional Interest thereon, if any, to the date
of purchase (the "Change of Control Payment"). Within 20 Business Days following
any Change of Control, the Authority shall mail a notice to each Holder setting
forth the procedures governing the Change of Control Offer as required by the
Indenture.

     (b) If the Authority or a Subsidiary consummates any Asset Sales, within
five Business Days of each date on which the aggregate amount of Excess Proceeds
exceeds $15.0 million, the Authority shall commence an offer to all Holders of
Senior Notes (as "Asset Sale Offer") pursuant to Section 3.10 of the Indenture
to purchase the maximum principal amount of
<PAGE>
 
Senior Notes that may be purchased out of the Excess Proceeds at an offer price
in cash in an amount equal to 100% of the principal amount thereof plus accrued
and unpaid interest and Additional Interest thereon, if any, to the date fixed
for the closing of such offer, in accordance with the procedures set forth in
the Indenture. To the extent that the aggregate amount of Senior Notes tendered
pursuant to an Asset Sale Offer is less than the Excess Proceeds, the Authority
(or such Subsidiary) may use such deficiency for any purpose not otherwise
permitted by the Indenture. If the aggregate principal amount of Senior Notes
surrendered by Holders thereof exceeds the amount of Excess Proceeds, the
Trustee shall select the Senior Notes to be purchased on a pro rata basis.
Holders of Senior Notes that are the subject of an offer to purchase will
receive an Asset Sale Offer from the Authority prior to any related purchase
date and may elect to have such Senior Notes purchased by completing the form
entitled "Option of Holder to Elect Purchase" on the reverse of the Senior
Notes.

     8. NOTICE OF REDEMPTION. Notice of redemption will be mailed at least 30
days but not more than 60 days before the redemption date to each Holder whose
Senior Notes are to be redeemed at its registered address. Senior Notes in
denominations larger than $1,000 may be redeemed in part but only in whole
multiples of $1,000, unless all of the Senior Notes held by a Holder are to be
redeemed. On and after the redemption date interest ceases to accrue on Senior
Notes or portions thereof called for redemption.

     9. DENOMINATIONS, TRANSFER, EXCHANGE. The Senior Notes are in registered
form without coupons in denominations of $1,000 and integral multiples of
$1,000. The transfer of Senior Notes may be registered and Senior Notes may be
exchanged as provided in the Indenture. The Registrar and the Trustee may
require a Holder, among other things, to furnish appropriate endorsements and
transfer documents and the Authority may require a Holder to pay any taxes and
fees required by law or permitted by the Indenture. The Authority need not
exchange or register the transfer of any Senior Note or portion of a Senior Note
selected for redemption, except for the unredeemed portion of any Senior Note
being redeemed in part. Also, the Authority need not exchange or register the
transfer of any Senior Notes for a period of 15 days before a selection of
Senior Notes to be redeemed or during the period between a record date and the
corresponding Interest Payment Date.

     This Regulation S Temporary Global Note is exchangeable in whole or in part
for one or more Global Notes only (i) on or after the termination of the 40-day
restricted period (as defined in Regulation S) and (ii) upon presentation of
certificates (accompanied by an Opinion of Counsel, if applicable) required by
Article 2 of the Indenture. Upon exchange of this Regulation S Temporary Global
Note for one or more Global Notes, the Trustee shall cancel this Regulation S
Temporary Note.

     10. PERSONS DEEMED OWNERS. The registered Holder of a Senior Note may be
treated as its owner for all purposes.

     11. AMENDMENT, SUPPLEMENT AND WAIVER. Subject to certain exceptions, the
Indenture, the Senior Subsidiary Guarantees or the Senior Notes may be amended
or supplemented with the consent of the Holders of at least a majority in
principal amount of the then outstanding Senior Notes voting as a single class,
and any existing default or compliance with any provision of the Indenture, the
Senior Subsidiary Guarantees or the Senior Notes may be waived with the consent
of the Holders of a majority in principal amount of the then outstanding Senior
Notes voting as a single class. Without the consent of any Holder of a Senior
<PAGE>
 
Note, the Indenture, the Senior Subsidiary Guarantees or the Senior Notes may be
amended or supplemented to cure any ambiguity, defect or inconsistency, to
provide for uncertificated Senior Notes in addition to or in place of
certificated Senior Notes, to provide for the assumption of the Authority's or
Subsidiary Guarantor's obligations to Holders of the Senior Notes by a successor
to the Authority or such Subsidiary Guarantor, to make any change that would
provide any additional rights or benefits to the Holders of the Senior Notes or
that does not adversely affect the legal rights under the Indenture of any such
Holder, to comply with the requirements of the SEC in order to effect or
maintain the qualification of the Indenture under the Trust Indenture Act, or to
allow any Subsidiary Guarantor to execute a supplemental indenture to the
Indenture and/or a Senior Subsidiary Guarantee with respect to the Senior Notes
provided that the Authority has obtained any required government approval to
ensure the enforceability of the Senior Notes and the Indenture.

     12. DEFAULTS AND REMEDIES. Events of Default include: (i) default for 30
days in the payment when due of interest or Additional Interest on the Senior
Notes; (ii) default in payment when due of principal of or premium, if any, on
the Senior Notes when the same becomes due and payable at maturity, upon
redemption (including in connection with an offer to purchase) or otherwise;
(iii) failure by the Authority or any of its Restricted Subsidiaries to comply
with Section 4.10 or 5.01 of the Indenture; (iv) failure by the Authority or any
of its Restricted Subsidiaries to observe or perform (A) any covenant described
in Section 4.07 or 4.09 of the Indenture for 30 days after notice to the
Authority by the Trustee or the Holders of at least 25% in aggregate principal
amount of the Senior Notes then outstanding voting as a single class or (B) any
other covenant, representation, warranty or other agreement in the Indenture or
the Senior Notes for 60 days after notice to the Authority by the Trustee or the
Holders of at least 25% in aggregate principal amount of the Senior Notes then
outstanding voting as a single class; (v) default under certain other agreements
relating to Indebtedness of the Authority or any of its Restricted Subsidiaries
which default results in the acceleration of such Indebtedness prior to its
express maturity; (vi) certain final judgments for the payment of money that
remain undischarged for a period of 60 days; (vii) certain events of bankruptcy
or insolvency with respect to the Authority or any of its Restricted
Subsidiaries; (viii) revocation, termination, suspension or other cessation of
effectiveness of any Gaming License which results in the cessation or suspension
of gaming operations for a period of more than 90 consecutive days at the
Resort; (ix) cessation of gaming operations for a period of more than 90
consecutive days at the Resort (other than as a result of a casualty loss); (x)
the Lease ceases to be in full force and effect; (xi) except as permitted by the
Indenture, any Senior Subsidiary Guarantee shall be held in any judicial
proceeding to be unenforceable or invalid or shall cease for any reason to be in
full force and effect or any Subsidiary Guarantor or any Person acting on its
behalf shall deny or disaffirm its obligations under such Subsidiary Guarantor's
Senior Subsidiary Guarantee; and (xii) failure by the Tribe to comply with the
provisions of Article 10 of the Indenture for 30 days after notice to the
Authority and the Tribe by the Trustee or the Holders of at least 25% in
aggregate principal amount of the Senior Notes then outstanding voting as a
single class. If any Event of Default occurs and is continuing, the Trustee or
the Holders of at least 25% in principal amount of the then outstanding Senior
Notes may declare all the Senior Notes to be due and payable. Notwithstanding
the foregoing, in the case of an Event of Default arising from certain events of
bankruptcy or insolvency, all outstanding Senior Notes will become due and
payable without further action or notice. Holders may not enforce the Indenture
or the Senior Notes except as provided in the Indenture. Subject to certain
limitations, Holders of a majority in principal amount of the then outstanding
Senior Notes may direct the Trustee in its exercise of
<PAGE>
 
any trust or power. The Trustee may withhold from Holders of the Senior Notes
notice of any continuing Default or Event of Default (except a Default or Event
of Default relating to the payment of principal or interest) if it determines
that withholding notice is in their interest. The Holders of a majority in
aggregate principal amount of the Senior Notes then outstanding by notice to the
Trustee may on behalf of the Holders of all of the Senior Notes waive any
existing Default or Event of Default and its consequences under the Indenture
except a continuing Default or Event of Default in the payment of interest on,
or the principal of, the Senior Notes. The Authority is required to deliver to
the Trustee annually a statement regarding compliance with the Indenture, and
the Authority is required upon becoming aware of any Default or Event of
Default, to deliver to the Trustee a statement specifying such Default or Event
of Default.

     13. TRUSTEE DEALINGS WITH AUTHORITY. The Trustee, in its individual or any
other capacity, may make loans to, accept deposits from, and perform services
for the Authority or its Affiliates, and may otherwise deal with the Authority
or its Affiliates, as if it were not the Trustee.

     14. NO RECOURSE AGAINST OTHERS. A controlling person, director, officer,
employee or holder of an Ownership Interest of the Authority, as such, shall not
have any liability for any obligations of the Authority under the Senior Notes
or the Indenture or for any claim based on, in respect of, or by reason of, such
obligations or their creation. Each Holder by accepting a Senior Note waives and
releases all such liability. The waiver and release are part of the
consideration for the issuance of the Senior Notes.

     15. AUTHENTICATION. This Senior Note shall not be valid until authenticated
by the manual signature of the Trustee or an authenticating agent.

     16. ABBREVIATIONS. Customary abbreviations may be used in the name of a
Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (=
tenants by the entireties), JT TEN (= joint tenants with right of survivorship
and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts
to Minors Act).

     17. ADDITIONAL RIGHTS OF HOLDERS OF RESTRICTED GLOBAL SENIOR NOTES AND
RESTRICTED DEFINITIVE SENIOR NOTES. In addition to the rights provided to
Holders of Senior Notes under the Indenture, Holders of Restricted Global Senior
Notes and Restricted Definitive Senior Notes shall have all the rights set forth
in the Senior Registration Rights Agreement dated as of March 3, 1999, between
the Authority and the parties named on the signature pages thereof (the "Senior
Registration Rights Agreement").

     18. CUSIP NUMBERS. Pursuant to a recommendation promulgated by the
Committee on Uniform Security Identification Procedures, the Authority has
caused CUSIP numbers to be printed on the Senior Notes and the Trustee may use
CUSIP numbers in notices of redemption as a convenience to Holders. No
representation is made as to the accuracy of such numbers either as printed on
the Senior Notes or as contained in any notice of redemption and reliance may be
placed only on the other identification numbers placed thereon.

     The Authority will furnish to any Holder upon written request and without
charge a copy of the Indenture and/or the Senior Registration Rights Agreement.

Note" attached thereto). Each Global Senior Subordinated Note shall represent
such of the outstanding Senior Subordinated Notes as shall be specified therein
and each shall provide that it shall represent the aggregate principal amount of
outstanding Senior Subordinated Notes from time to time endorsed thereon and
that the aggregate principal amount of outstanding Senior Subordinated Notes
represented thereby may from time to time be reduced or increased, as
appropriate, to reflect exchanges and redemptions. Any endorsement of a Global
Senior Subordinated Note to reflect the amount of any increase or decrease in
the aggregate principal amount of outstanding Senior Subordinated Notes
represented thereby shall be made by the Trustee or the Custodian, at the
direction of the Trustee, in accordance with instructions given by the Holder
thereof as required by Section 2.06 hereof.

the Depositary, and registered in the name of the Depositary or the nominee of
the Depositary for the accounts of designated agents holding on behalf of
Euroclear or Cedel Bank, duly executed by the Authority and authenticated by the
Trustee as hereinafter provided. The Distribution Compliance Period shall be
terminated upon the receipt by the Trustee of (i) a written certificate from the
Depositary, together with copies of certificates from Euroclear and Cedel Bank
certifying that they have received certification of non-United States beneficial
ownership of 100% of the aggregate principal amount of the Regulation S

beneficial owners thereof who acquired an interest therein during the
Distribution Compliance Period pursuant to another exemption from registration
under the Securities Act and who will take delivery of a beneficial ownership
interest in a 144A Global Senior Subordinated Note bearing a Private Placement
Legend, all as contemplated by Section 2.06(a)(ii) hereof), and (ii) an
Officers' Certificate from the Authority. Following the termination of the
Distribution Compliance Period, beneficial interests in the Regulation S
Temporary Global Senior Subordinated Note shall be exchanged for beneficial
interests in Regulation S Permanent Global Senior Subordinated Notes pursuant to
the Applicable Procedures. Simultaneously with the authentication of Regulation
S Permanent Global Senior Subordinated Notes, the Trustee shall cancel the
Regulation S Temporary Global Senior Subordinated Note. The aggregate principal
amount of the Regulation S Temporary Global Senior Subordinated Note and the
Regulation S Permanent Global Senior Subordinated Notes may from time to time be
increased or decreased by adjustments made on the records of the Trustee and the
Depositary or its nominee, as the case may be, in connection with transfers of
interest as hereinafter provided.

     (d) Euroclear and Cedel Procedures Applicable. The provisions of the

     Two Officers of the Authority shall sign the Senior Subordinated Notes for

Senior Subordinated Note shall nevertheless be valid.

     A Senior Subordinated Note shall not be valid until authenticated by the
manual signature of the Trustee. The signature shall be conclusive evidence that
the Senior Subordinated Note has been authenticated under this Indenture.

     The Trustee shall, upon a written order of the Authority signed by two
Officers of the Authority (an "Authentication Order"), authenticate Senior
Subordinated Notes for original issue up to the aggregate principal amount not
to exceed $300,000,000 (other than as provided in Section 2.07 hereof) in one or
more series, which order shall specify whether such notes are Initial Senior
Subordinated Notes or Senior Subordinated Exchange Notes.

     The Senior Subordinated Notes shall be issued only in fully registered
form, without coupons and only in denominations of $1,000 and any integral
multiple thereof. All Senior Subordinated Notes issued under this Indenture
shall vote and consent together on all matters as one class and no series of
Senior Subordinated Notes will have the right to vote or consent as a separate
class on any matter.

     The Trustee may appoint an authenticating agent acceptable to the Authority
to authenticate Senior Subordinated Notes. An authenticating agent may
authenticate Senior Subordinated Notes whenever the Trustee may do so. Each
reference in this Indenture to authentication by the Trustee includes
authentication by such agent. An authenticating agent has the same rights as an
Agent to deal with Holders or an Affiliate of the Authority.

Section 2.03.  Registrar and Paying Agent.

     The Authority shall maintain an office or agency where Senior Subordinated
Notes may be presented for registration of transfer or for exchange
("Registrar") and an office or agency where Senior Subordinated Notes may be
presented for payment ("Paying Agent"). The Registrar shall keep a register of
the Senior Subordinated Notes and of their transfer and exchange. The Authority
may appoint one or more co-registrars and one or more additional paying agents.
The term "Registrar" includes any co-registrar and the term "Paying Agent"
includes any additional paying agent. The Authority may change any Paying Agent
or Registrar without notice to any Holder. The Authority shall notify the
Trustee in writing of the name and address of any Agent not a party to this
Indenture. If the Authority fails to appoint or maintain another entity as
Registrar or Paying Agent, the Trustee shall act as such. The Authority or any
of its Restricted Subsidiaries may act as Paying Agent or Registrar.

     The Authority initially appoints The Depository Trust Company ("DTC") to
act as Depositary with respect to the Global Senior Subordinated Notes.

     The Authority initially appoints the Trustee to act as the Registrar and
Paying Agent and to act as Custodian with respect to the Global Senior

Section 2.04.  Paying Agent to Hold Money in Trust.

     The Authority shall require each Paying Agent other than the Trustee to
agree in writing that the Paying Agent will hold in trust for the benefit of
Holders or the Trustee all money held by the Paying Agent for the payment of
principal, premium or Additional Interest, if any, or interest on the Senior
Subordinated Notes, and will notify the Trustee of any default by the Authority
in making any such payment. While any such default continues, the Trustee may
require a Paying Agent to pay all money held by it to the Trustee. The Authority
at any time may require a Paying Agent to pay all money held by it to the
Trustee. Upon payment over to the Trustee, the Paying Agent (if other than the
Authority or a Restricted Subsidiary or an Affiliate) shall have no further
liability for the money. If the Authority or a Restricted Subsidiary acts as
Paying Agent, it shall segregate and hold in a separate trust fund for the


                                       23

benefit of the Holders all money held by it as Paying Agent. Upon any bankruptcy
or reorganization proceedings relating to the Authority, the Trustee shall serve
as Paying Agent for the Senior Subordinated Notes.

Section 2.05.  Holder Lists.

     The Trustee shall preserve in as current a form as is reasonably
practicable the most recent list available to it of the names and addresses of
all Holders and shall otherwise comply with TIA ss. 312(a). If the Trustee is
not the Registrar, the Authority shall furnish to the Trustee at least seven
Business Days before each interest payment date and at such other times as the
Trustee may request in writing, a list in such form and as of such date as the
Trustee may reasonably require of the names and addresses of the Holders of
Senior Subordinated Notes and the Authority shall otherwise comply with TIA ss.

Depositary to a nominee of the Depositary, by a nominee of the Depositary to the
Depositary or to another nominee of the Depositary, or by the Depositary or any
such nominee to a successor Depositary or a nominee of such successor
Depositary. All Global Senior Subordinated Notes will be exchanged by the
Authority for Definitive Senior Subordinated Notes if (i) the Authority delivers
to the Trustee notice from the Depositary that it is unwilling or unable to
continue to act as Depositary or that it is no longer a clearing agency
registered under the Exchange Act and, in either case, a successor Depositary is
not appointed by the Authority within 120 days after the date of such notice
from the Depositary or (ii) the Authority in its sole discretion determines that
the Global Senior Subordinated Notes (in whole but not in part) should be
exchanged for Definitive Senior Subordinated Notes and delivers a written notice
to such effect to the Trustee; provided that in no event shall the Regulation S
Temporary Global Senior Subordinated Note be exchanged by the Authority for
Definitive Senior Subordinated Notes prior to (x) the expiration of the
Distribution Compliance Period and (y) the receipt by the Registrar of any
certificates required pursuant to Rule 903(c)(3)(ii)(B) under the Securities
Act. Upon the occurrence of either of the preceding events in (i) or (ii) above,

Depositary shall instruct the Trustee. Global Senior Subordinated Notes also may
be exchanged or replaced, in whole or in part, as provided in Sections 2.07 and
2.10 hereof. Every Senior Subordinated Note authenticated and delivered in
exchange for, or in lieu of, a Global Senior Subordinated Note or any portion
thereof, pursuant to this Section 2.06 or Section 2.07 or 2.10 hereof, shall be
authenticated and delivered in the form of, and shall be, a Global Senior
Subordinated Note. A Global Senior Subordinated Note may not be exchanged for

     Global Senior Subordinated Note prior to (x) the expiration of the
     Distribution Compliance Period and (y) the receipt by the Registrar of any

     selected for redemption in whole or in part, except the unredeemed portion
     of any Senior Subordinated Note being redeemed in part or (C) to register
     the transfer of or to exchange a Senior Subordinated Note between a record
     date and the next succeeding Interest Payment Date.

          (vi) Prior to due presentment for the registration of a transfer of
     any Senior Subordinated Note, the Trustee, any Agent and the Authority may
     deem and treat the Person in whose name any Senior Subordinated Note is
     registered as the absolute owner of such Senior Subordinated Note for the
     purpose of receiving payment of principal of and interest on such Senior
     Subordinated Notes and for all other purposes, and none of the Trustee, any
     Agent or the Authority shall be affected by notice to the contrary.

          (vii) The Trustee shall authenticate Global Senior Subordinated Notes
     and Definitive Senior Subordinated Notes in accordance with the provisions
     of Section 2.02 hereof.

          (viii) All certifications, certificates and Opinions of Counsel
     required to be submitted to the Registrar pursuant to this Section 2.06 to
     effect a registration of transfer or exchange may be submitted by
     facsimile.

Section 2.07.  Replacement Senior Subordinated Notes.

     If any mutilated Senior Subordinated Note is surrendered to the Trustee or
the Authority and the Trustee receives evidence to its satisfaction of the
destruction, loss or theft of any Senior Subordinated Note, the Authority shall
issue and the Trustee, upon receipt of an Authentication Order, shall
authenticate a replacement Senior Subordinated Note in accordance with this
Indenture. If required by the Trustee or the Authority, an indemnity bond must
be supplied by the Holder that is sufficient in the judgment of the Trustee and
the Authority to protect the Authority, the Trustee, any Agent and any
authenticating agent from any loss that any of them may suffer if a Senior
Subordinated Note is replaced. The Authority may charge for its expenses in
replacing a Senior Subordinated Note.

     Every replacement Senior Subordinated Note is an additional obligation of
the Authority and shall be entitled to all of the benefits of this Indenture
equally and proportionately with all other Senior Subordinated Notes duly issued
hereunder.

Section 2.08.  Outstanding Senior Subordinated Notes.

     The Senior Subordinated Notes outstanding at any time are all the Senior
Subordinated Notes authenticated by the Trustee except for those canceled by it,
those delivered to it for cancellation, those reductions in the interest in a
Global Senior Subordinated Note effected by the Trustee in accordance with the
provisions hereof, and those described in this Section as not outstanding.
Except as set forth in Section 2.09 hereof, a Senior Subordinated Note does not
cease to be outstanding because the Authority or an Affiliate of the Authority
holds the Senior Subordinated Note.

     If a Senior Subordinated Note is replaced pursuant to Section 2.07 hereof,
it ceases to be outstanding unless the Trustee receives proof satisfactory to it
that the replaced Senior Subordinated Note is held by a bona fide purchaser.

     If the principal amount of any Senior Subordinated Note is considered paid
under Section 4.01 hereof, it ceases to be outstanding and interest on it ceases
to accrue.

     If the Paying Agent (other than the Authority, a Subsidiary or an Affiliate
of any thereof) holds, on a redemption date or maturity date, money sufficient
to pay Senior Subordinated Notes payable on that date, then on and after that
date such Senior Subordinated Notes shall be deemed to be no longer outstanding
and shall cease to accrue interest.

Section 2.09.  Treasury Senior Subordinated Notes.

     In determining whether the Holders of the required principal amount of
Senior Subordinated Notes have concurred in any direction, waiver or consent,
Senior Subordinated Notes owned by the Authority, or by any Person directly or
indirectly controlling or controlled by or under direct or indirect common
control with the Authority, shall be considered as though not outstanding,
except that for the purposes of determining whether the Trustee shall be
protected in relying on any such direction, waiver or consent, only Senior
Subordinated Notes that the Trustee actually knows are so owned shall be so
disregarded.

Section 2.10.  Temporary Senior Subordinated Notes.

     Until certificates representing Senior Subordinated Notes are ready for
delivery, the Authority may prepare and the Trustee, upon receipt of an
Authentication Order, shall authenticate temporary Senior Subordinated Notes.
Temporary Senior Subordinated Notes shall be substantially in the form of
certificated Senior Subordinated Notes but may have variations that the
Authority considers appropriate for temporary Senior Subordinated Notes and as
shall be reasonably acceptable to the Trustee. Without unreasonable delay, the
Authority shall prepare and the Trustee shall authenticate definitive Senior
Subordinated Notes in exchange for temporary Senior Subordinated Notes.

     Holders of temporary Senior Subordinated Notes shall be entitled to all of
the benefits of this Indenture.

Section 2.11.  Cancellation.

     The Authority at any time may deliver Senior Subordinated Notes to the
Trustee for cancellation. The Registrar and Paying Agent shall forward to the
Trustee any Senior Subordinated Notes surrendered to them for registration of
transfer, exchange or payment. The Trustee and no one else shall cancel all
Senior Subordinated Notes surrendered for registration of transfer, exchange,
payment, replacement or cancellation and shall destroy canceled Senior
Subordinated Notes (subject to the record


                                       36

retention requirement of the Exchange Act). Certification of the destruction of
all canceled Senior Subordinated Notes shall be delivered to the Authority. The
Authority may not issue new Senior Subordinated Notes to replace Senior
Subordinated Notes that it has paid or that have been delivered to the Trustee
for cancellation.

Section 2.12.  Defaulted Interest.

     If the Authority defaults in a payment of interest on the Senior
Subordinated Notes, it shall pay the defaulted interest in any lawful manner
plus, to the extent lawful, interest payable on the defaulted interest, to the
Persons who are Holders on a subsequent special record date, in each case at the
rate provided in the Senior Subordinated Notes and in Section 4.01 hereof. The
Authority shall notify the Trustee in writing of the amount of defaulted
interest proposed to be paid on each Senior Subordinated Note and the date of
the proposed payment. The Authority shall fix or cause to be fixed each such
special record date and payment date, provided that no such special record date
shall be less than 10 days prior to the related payment date for such defaulted
interest. At least 15 days before the special record date, the Authority (or,
upon the written request of the Authority, the Trustee in the name and at the
expense of the Authority) shall mail or cause to be mailed to Holders a notice
that states the special record date, the related payment date and the amount of
such interest to be paid.

Section 2.13.  CUSIP Numbers.

     The Authority in issuing the Senior Subordinated Notes may use "CUSIP"
numbers (if then generally in use), and, if so, the Trustee shall use CUSIP
numbers in notices of redemption as a convenience to Holders; provided that any
such notice may state that no representation is made as to the correctness of
such numbers either as printed on the Senior Subordinated Notes or as contained
in any notice of a redemption and that reliance may be placed only on the other
identification numbers printed on the Senior Subordinated Notes, and any such
redemption shall not be affected by any defect in or the omission of such
numbers. The Authority will promptly notify the Trustee of any change in the
CUSIP numbers.

                            REDEMPTION AND PREPAYMENT

Section 3.01.  Notices to Trustee.

     If the Authority elects to redeem Senior Subordinated Notes pursuant to the
optional redemption provisions of Section 3.07 hereof, it shall furnish to the
Trustee, at least 30 days but not more than 60 days before a redemption date, an
Officers' Certificate setting forth (i) the clause of this Indenture pursuant to
which the redemption shall occur, (ii) the redemption date, (iii) the principal
amount of Senior Subordinated Notes to be redeemed, (iv) the redemption price
and (v) if applicable, any redemption requirements of the principal national
securities exchange on which the Senior Subordinated Notes are listed.

Section 3.02.  Selection of Senior Subordinated Notes to Be Redeemed.

     If less than all of the Senior Subordinated Notes are to be redeemed or
purchased in an offer to purchase at any time, the Trustee shall select the
Senior Subordinated Notes to be redeemed or purchased among the Holders of the
Senior Subordinated Notes in compliance with any requirements of the principal
national securities exchange, if any, on which the Senior Subordinated Notes are
listed as set forth in the Officers' Certificate delivered pursuant to Section
3.01 or, if the Senior Subordinated Notes are not so listed or if the
requirements are not set forth in such Officers' Certificate, on a pro rata
basis,

by lot or in accordance with any other method the Trustee considers fair and
appropriate. In the event of partial redemption by lot, the particular Senior
Subordinated Notes to be redeemed shall be selected, unless otherwise provided
herein, not less than 30 nor more than 60 days prior to the redemption date by
the Trustee from the outstanding Senior Subordinated Notes not previously called
for redemption.

     The Trustee shall promptly notify the Authority in writing of the Senior
Subordinated Notes selected for redemption and, in the case of any Senior
Subordinated Note selected for partial redemption, the principal amount thereof
to be redeemed. Senior Subordinated Notes and portions of Senior Subordinated
Notes selected shall be in amounts of $1,000 or whole multiples of $1,000,
except that if all of the Senior Subordinated Notes of a Holder are to be
redeemed, the entire outstanding amount of Senior Subordinated Notes held by
such Holder, even if not a multiple of $1,000, shall be redeemed. Except as
provided in the preceding sentence, provisions of this Indenture that apply to
Senior Subordinated Notes called for redemption also apply to portions of Senior
Subordinated Notes called for redemption.

Section 3.03.  Notice of Redemption.

     Subject to the provisions of Section 3.10 hereof, at least 30 days but not
more than 60 days before a redemption date, the Authority shall mail or cause to
be mailed, by first class mail, a notice of redemption to each Holder whose
Senior Subordinated Notes are to be redeemed at its registered address.

     The notice shall identify the Senior Subordinated Notes to be redeemed and
shall state:

     (a) the redemption date;

     (b) the redemption price;

     (c) if any Senior Subordinated Note is being redeemed in part, the portion
of the principal amount of such Senior Subordinated Note to be redeemed and
that, after the redemption date upon surrender of such Senior Subordinated Note,
a new Senior Subordinated Note or Senior Subordinated Notes in principal amount
equal to the unredeemed portion shall be issued upon cancellation of the
original Senior Subordinated Note;

     (d) the name and address of the Paying Agent;

     (e) that Senior Subordinated Notes called for redemption must be
surrendered to the Paying Agent to collect the redemption price;

     (f) that, unless the Authority defaults in making such redemption payment,
interest on Senior Subordinated Notes called for redemption ceases to accrue on
and after the redemption date;

     (g) the paragraph of the Senior Subordinated Notes and/or Section of this
Indenture pursuant to which the Senior Subordinated Notes called for redemption
are being redeemed; and

     (h) that no representation is made as to the correctness or accuracy of the
CUSIP number, if any, listed in such notice or printed on the Senior
Subordinated Notes.

     At the Authority's request, the Trustee shall give the notice of redemption
in the Authority's name and at its expense; provided, however, that the
Authority shall have delivered to the Trustee, at least 45 days prior to the
redemption date (unless a shorter period shall be satisfactory to the Trustee),
an Officers' Certificate requesting that the Trustee give such notice and
setting forth the information to be stated in such notice as provided in the
preceding paragraph.

<PAGE>
 
Section 3.04.  Effect of Notice of Redemption.

     Once notice of redemption is mailed in accordance with Section 3.03 hereof,
Senior Subordinated Notes called for redemption become irrevocably due and
payable on the redemption date at the redemption price. A notice of redemption
may not be conditional.

Section 3.05.  Deposit of Redemption Price.

     One Business Day prior to the redemption date, the Authority shall deposit
with the Trustee or with the Paying Agent money sufficient to pay the redemption
price of and accrued interest on all Senior Subordinated Notes to be redeemed on
that date. The Trustee or the Paying Agent shall promptly return to the
Authority any money deposited with the Trustee or the Paying Agent by the
Authority in excess of the amounts necessary to pay the redemption price of, and
accrued interest on, all Senior Subordinated Notes to be redeemed.

     If the Authority complies with the provisions of the preceding paragraph,
on and after the redemption date, interest shall cease to accrue on the Senior
Subordinated Notes or the portions of Senior Subordinated Notes called for
redemption. If a Senior Subordinated Note is redeemed on or after an interest
record date but on or prior to the related interest payment date, then any
accrued and unpaid interest shall be paid to the Person in whose name such
Senior Subordinated Note was registered at the close of business on such record
date. If any Senior Subordinated Note called for redemption shall not be so paid
upon surrender for redemption because of the failure of the Authority to comply
with the preceding paragraph, interest shall be paid on the unpaid principal,
from the redemption date until such principal is paid, and to the extent lawful
on any interest not paid on such unpaid principal, in each case at the rate
provided in the Senior Subordinated Notes and in Section 4.01 hereof.

Section 3.06.  Senior Subordinated Notes Redeemed in Part.

     Upon surrender of a Senior Subordinated Note that is redeemed in part, the
Authority shall issue and, upon the Authority's written request, the Trustee
shall authenticate for the Holder at the expense of the Authority a new Senior
Subordinated Note equal in principal amount to the unredeemed portion of the
Senior Subordinated Note surrendered.

Section 3.07.  Optional Redemption.

     (a) Except as set forth in Section 3.08, the Authority shall not have the
option to redeem the Senior Subordinated Notes pursuant to this Section 3.07
prior to January 1, 2004. On or after such date, the Authority shall have the
option to redeem the Senior Subordinated Notes, in whole or in part, at the
redemption prices (expressed as percentages of principal amount) set forth below
plus accrued and unpaid interest thereon, if any, to the applicable redemption
date, if redeemed during the twelve-month period beginning on January 1 of the

Section 3.08.  Redemption Pursuant to Gaming Law

     (a) Notwithstanding any other provisions of this Article 3, if any Gaming
Regulatory Authority requires that a Holder or beneficial owner of the Senior
Subordinated Notes must be licensed, qualified or found suitable under any
applicable gaming laws in order to maintain any gaming license or franchise of
the Authority under any applicable gaming laws, and the Holder or beneficial
owner fails to apply for a license, qualification or finding of suitability
within 30 days after being requested to do so by such Gaming Regulatory
Authority (or such lesser period that may be required by such Gaming Regulatory)
or if such Holder or beneficial owner is not so licensed, qualified or found
suitable, the Authority has the right, at its option, (i) to require such Holder
or beneficial owner to dispose of such Holder's or beneficial owner's Senior
Subordinated Notes within 30 days of receipt of such finding by the applicable
Gaming Regulatory Authority (or such earlier date as may be required by the
applicable Gaming Regulatory Authority); or (ii) to call for redemption of the
Senior Subordinated Notes of such Holder or beneficial owner at a redemption
price equal to the lesser of (1) the principal amount thereof or (2) the price
at which such Holder or beneficial owner acquired the Senior Subordinated Notes
or (3) the current market price of the Senior Subordinated Notes, together with,
in each case, accrued and unpaid interest and Additional Interest, if any, to
the earlier of the date of redemption or the date of the finding of
unsuitability by such Gaming Regulatory Authority, which may be less than 30
days following the notice of redemption if so ordered by such Gaming Regulatory
Authority.

     (b) In connection with any redemption pursuant to this Section 3.08, and
except as may be required by a Gaming Regulatory Authority, the Authority shall
comply with Sections 3.01 through 3.06 hereof.

     (c) The Authority shall not be required to pay or reimburse any Holder or
beneficial owner of Senior Subordinated Notes who is required to apply for such
license, qualification or finding of suitability for the costs of the licensure
or investigation for such qualification or finding of suitability. Such expenses
shall be the obligation of such Holder or beneficial owner.

Section 3.09.  Mandatory Redemption.

     The Authority shall not be required to make mandatory redemption payments
with respect to the Senior Subordinated Notes.

Section 3.10.  Offer to Purchase by Application of Excess Proceeds.

     In the event that, pursuant to Section 4.10 hereof, the Authority shall be
required to commence an offer to all Holders to purchase Senior Subordinated
Notes (an "Asset Sale Offer"), it shall follow the procedures specified below.

     The Asset Sale Offer shall remain open for a period of 20 Business Days
following its commencement and no longer, except to the extent that a longer
period is required by applicable law (the "Offer Period"). No later than five
Business Days after the termination of the Offer Period (the "Purchase Date"),
the Authority shall purchase the principal amount of Senior Subordinated Notes
required to be purchased pursuant to Section 4.10 hereof (the "Offer Amount")
or, if less than the Offer Amount has been tendered, all Senior Subordinated
Notes tendered in response to the Asset Sale Offer. Payment for any Senior
Subordinated Notes so purchased shall be made in the same manner as interest
payments are made.

     If the Purchase Date is on or after an interest record date and on or
before the related interest payment date, any accrued and unpaid interest shall
be paid to the Person in whose name a Senior

<PAGE>
 
Subordinated Note is registered at the close of business on such record date,
and no additional interest shall be payable to Holders who tender Senior
Subordinated Notes pursuant to the Asset Sale Offer.

     Upon the commencement of an Asset Sale Offer, the Authority shall send, by
first class mail, a notice to the Trustee and each of the Holders, with a copy
to the Trustee. The notice shall contain all instructions and materials
necessary to enable such Holders to tender Senior Subordinated Notes pursuant to
the Asset Sale Offer. The Asset Sale Offer shall be made to all Holders. The
notice, which shall govern the terms of the Asset Sale Offer, shall state:

     (a) that the Asset Sale Offer is being made pursuant to this Section 3.10
and Section 4.10 hereof and the length of time the Asset Sale Offer shall remain
open;

     (b) the Offer Amount, the purchase price and the Purchase Date;

     (c) that any Senior Subordinated Note not tendered or accepted for payment
shall continue to accrue interest;

Subordinated Note accepted for payment pursuant to the Asset Sale Offer shall
cease to accrue interest after the Purchase Date;

     (e) that Holders electing to have a Senior Subordinated Note purchased
pursuant to an Asset Sale Offer may elect to have Senior Subordinated Notes
purchased in integral multiples of $1,000 only;

     (f) that Holders electing to have a Senior Subordinated Note purchased
pursuant to any Asset Sale Offer shall be required to surrender the Senior
Subordinated Note, with the form entitled "Option of Holder to Elect Purchase"
on the reverse of the Senior Subordinated Note completed, or transfer by
book-entry transfer, to the Authority, a depositary, if appointed by the
Authority, or a paying agent at the address specified in the notice at least
three days before the Purchase Date;

     (g) that Holders shall be entitled to withdraw their election if the
Authority, the depositary or the paying agent, as the case may be, receives, not
later than the expiration of the Offer Period, a telegram, telex, facsimile
transmission or letter setting forth the name of the Holder, the principal
amount of the Senior Subordinated Note the Holder delivered for purchase and a
statement that such Holder is withdrawing his election to have such Senior
Subordinated Note purchased;

     (h) that, if the aggregate principal amount of Senior Subordinated Notes
surrendered by Holders exceeds the Offer Amount, the Authority shall select the
Senior Subordinated Notes to be purchased on a pro rata basis (with such
adjustments as may be deemed appropriate by the Authority so that only Senior
Subordinated Notes in denominations of $1,000, or integral multiples thereof,
shall be purchased); and

     (i) that Holders whose Senior Subordinated Notes were purchased only in
part shall be issued new Senior Subordinated Notes equal in principal amount to
the unpurchased portion of the Senior Subordinated Notes surrendered (or
transferred by book-entry transfer).

     On or before the Purchase Date, the Authority shall, to the extent lawful,
accept for payment, on a pro rata basis to the extent necessary, the Offer
Amount of Senior Subordinated Notes or portions thereof tendered pursuant to the
Asset Sale Offer, or if less than the Offer Amount has been tendered, all Senior
Subordinated Notes tendered, and shall deliver to the Trustee an Officers'
Certificate stating that such Senior Subordinated Notes or portions thereof were
accepted for payment by the Authority in

accordance with the terms of this Section 3.10. The Authority, the Depositary or
the Paying Agent, as the case may be, shall promptly (but in any case not later
than five Business Days after the Purchase Date) mail or deliver to each
tendering Holder an amount equal to the purchase price of the Senior
Subordinated Notes tendered by such Holder and accepted by the Authority for
purchase, and the Authority shall promptly issue a new Senior Subordinated Note,
and the Trustee, upon written request from the Authority shall authenticate and
mail or deliver such new Senior Subordinated Note to such Holder, in a principal
amount equal to any unpurchased portion of the Senior Subordinated Note
surrendered. Any Senior Subordinated Note not so accepted shall be promptly
mailed or delivered by the Authority to the Holder thereof. The Authority shall
publicly announce the results of the Asset Sale Offer on the Purchase Date.

     Other than as specifically provided in this Section 3.10, any purchase
pursuant to this Section 3.10 shall be made pursuant to the provisions of
Sections 3.01 through 3.06 hereof.

     (a) The Authority shall pay or cause to be paid the principal of, premium,
if any, and interest on the Senior Subordinated Notes on the dates and in the
manner provided in the Senior Subordinated Notes. Principal, premium, if any,
and interest and Additional Interest, if any, shall be considered paid on the

thereof, holds as of 10:00 a.m. Eastern Time on the due date money deposited by
the Authority in immediately available funds and designated for and sufficient

Subordinated Notes to the extent lawful; it shall pay interest (including
post-petition interest in any proceeding under any Bankruptcy Law) on overdue
installments of interest (without regard to any applicable grace period) at the
same rate to the extent lawful.

Section 4.02.  Maintenance of Office or Agency.

     (a) The Authority shall maintain in the Borough of Manhattan, the City of
New York, an office or agency (which may be an office of the Trustee or an
Affiliate of the Trustee, Registrar or co-registrar) where Senior Subordinated
Notes may be surrendered for registration of transfer or for exchange and where
notices and demands to or upon the Authority in respect of the Senior
Subordinated Notes and this Indenture may be served. The Authority shall give
prompt written notice to the Trustee of the location, and any change in the

with the address thereof, such presentations, surrenders, notices and demands
may be made or served at the Corporate Trust Office of the Trustee.

     (b) The Authority may also from time to time designate one or more other
offices or agencies where the Senior Subordinated Notes may be presented or
surrendered for any or all such purposes and may from time to time rescind such
designations; provided, however, that no such designation or rescission shall in
any manner relieve the Authority of its obligation to maintain an office or
agency in the Borough of Manhattan, the City of New York for such purposes. The
Authority shall

            operations of the Authority and its Restricted Subsidiaries separate
            from the financial condition and results of operations of the
            Unrestricted Subsidiaries of the Authority, to the extent that would
            be required by the rules, regulations or interpretive positions of
            the SEC) and, with respect to the annual information only, a report
            thereon by the Authority's independent public accountants; and

     (ii)   all current reports that would be required to be filed with the SEC
            on Form 8-K if the Authority were required to file such reports.

     (b) In the event that the Authority consummates an Exchange Offer, whether
or not required by the rules and regulations of the SEC, the Authority will file
a copy of all such information and reports with the SEC for public availability
within the time periods specified in the SEC's rules and regulations (unless the
SEC will not accept such a filing) and make such information available to
securities analysts and prospective investors upon request.

     (c) The Authority has agreed that, for so long as any Senior Subordinated
Notes remain outstanding, it will furnish to the Holders and to securities
analysts and prospective investors, upon their request, the information required
to be delivered pursuant to Rule 144A(d)(4) under the Securities Act.

     (d) The Authority shall file with the Trustee and provide to Holders of
Senior Subordinated Notes, within 15 days after it files them with the NIGC,
copies of all reports which the Authority is required to file with the NIGC
pursuant to 25 C.F.R. Part 514.

     (e) The Authority shall at all times comply with TIA ss. 314(a).

Section 4.04.  Compliance Certificate.

     (a) The Authority shall deliver to the Trustee, within 90 days after the
end of each fiscal year, an Officers' Certificate stating that a review of the
activities of the Authority and its Subsidiaries during the preceding fiscal
year has been made under the supervision of the signing Officers with a view

to determining whether the Authority has kept, observed, performed and fulfilled
its obligations under this Indenture, and further stating, as to each such
Officer signing such certificate, that to the best of his or her knowledge the
Authority has kept, observed, performed and fulfilled each and every covenant
contained in this Indenture and is not in default in the performance or
observance of any of the terms, provisions and conditions of this Indenture (or,
if a Default or Event of Default shall have occurred, describing all such
Defaults or Events of Default of which he or she may have knowledge and what
action the Authority is taking or proposes to take with respect thereto) and
that to the best of his or her knowledge no event has occurred and remains in
existence by reason of which payments on account of the principal of or
interest, if any, on the Senior Subordinated Notes is prohibited or if such
event has occurred, a description of the event and what action the Authority is
taking or proposes to take with respect thereto.

     (b) So long as not contrary to the then current recommendations of the
American Institute of Certified Public Accountants, the year-end financial
statements delivered pursuant to Section 4.03(a) above shall be accompanied by a
written statement of the Authority's independent public accountants (who shall
be a firm of established national reputation) that in making the examination
necessary for certification of such financial statements, nothing has come to
their attention that would lead them to believe that the Authority has violated
any provisions of Article 4 or Article 5 hereof or, if any such violation has
occurred, specifying the nature and period of existence thereof, it being
understood that such accountants shall not be liable directly or indirectly to
any Person for any failure to obtain knowledge of any such violation.

     (c) The Authority shall, so long as any of the Senior Subordinated Notes
are outstanding, deliver to the Trustee, forthwith upon any Officer becoming
aware of any Default or Event of Default, an Officers' Certificate specifying
such Default or Event of Default and what action the Authority is taking or
proposes to take with respect thereto.

Section 4.05.  Taxes.

     The Authority shall pay, and shall cause each of its Subsidiaries to pay,
prior to delinquency, all material taxes, assessments, and governmental levies
except such as are contested in good faith and by appropriate proceedings or
where the failure to effect such payment is not adverse in any material respect
to the Holders of the Senior Subordinated Notes.

Section 4.06.  Stay, Extension and Usury Laws.

     The Authority covenants (to the extent that it may lawfully do so) that it
shall not at any time insist upon, plead, or in any manner whatsoever claim or
take the benefit or advantage of, any stay, extension or usury law wherever
enacted, now or at any time hereafter in force, that may affect the covenants or
the performance of this Indenture; and the Authority (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such
law, and covenants that it shall not, by resort to any such law, hinder, delay
or impede the execution of any power herein granted to the Trustee, but shall
suffer and permit the execution of every such power as though no such law has
been enacted.

Section 4.07.  Restricted Payments.

     (a) The Authority will not, and the Authority will not permit any of its
Restricted Subsidiaries, directly or indirectly, to: (i) make any payment on or
with respect to any of the Authority's or any of its Restricted Subsidiaries'
Equity Interests; (ii) purchase, redeem, defease or otherwise acquire or retire
for


                                       44
                                                       Senior Subordinated Notes
<PAGE>
 
value any Equity Interest in the Authority held by the Tribe or any Affiliate of
the Tribe; (iii) make any payment on or with respect to, or purchase, redeem,
defease or otherwise acquire or retire for value any Subordinated Indebtedness
(other than the defeasance and the ultimate redemption of the Junior
Subordinated Notes in accordance with their terms and the terms of the
Defeasance Trust), except a payment of interest or principal at Stated Maturity
thereof; (iv) make any payment or distribution to the Tribe (or any other
agency, instrumentality or political subunit thereof) or make any general
distribution to the members of the Tribe (other than Government Service
Payments); or (v) make any Restricted Investment; (all such payments and other
actions set forth in clauses (i) through (v) are collectively referred to as
"Restricted Payments") unless, at the time of and after giving effect to such
Restricted Payment:

     (A)  no Default or Event of Default shall have occurred and be continuing
          or would occur as a consequence thereof;

     (B)  the Authority would, at the time of such Restricted Payment and after
          giving pro forma effect thereto as if such Restricted Payment had been
          made at the beginning of the applicable four-quarter period, have been
          permitted to incur at least $1.00 of additional Indebtedness pursuant
          to the Fixed Charge Coverage Ratio test set forth in Section 4.09(a);
          and

     (C)  such Restricted Payment, together with the aggregate amount of all
          other Restricted Payments made by the Authority and its Restricted
          Subsidiaries after the date of this Indenture (excluding Restricted
          Payments permitted by clauses (ii), (iii), (iv) and (v) of Section
          4.07(b)), is less than the sum, without duplication, of (1) 50% of the
          Consolidated Net Income of the Authority for the period (taken as one
          accounting period) from the beginning of the first fiscal quarter
          commencing after the date of this Indenture to the end of the
          Authority's most recently ended fiscal quarter for which internal
          financial statements are available at the time of such Restricted
          Payment (or, if such Consolidated Net Income for such period is a
          deficit, less 100% of such deficit), plus (2) 100% of the aggregate
          net cash proceeds or fair market value (as determined in good faith by
          the Management Board and evidenced by a resolution set forth in an
          Officers' Certificate delivered to the Trustee) of assets or property
          (other than cash) received by the Authority from capital contributions
          from the Tribe that bear no mandatory obligation to repay the Tribe
          and other than from a Restricted Subsidiary of the Authority, plus (3)
          to the extent that any Restricted Investment that was made after the
          date of this Indenture is sold, liquidated or otherwise disposed of
          for cash or an amount equal to the fair market value thereof (as
          determined in good faith by the Management Board and evidenced by a
          resolution set forth in an Officers' Certificate delivered to the
          Trustee), the lesser of (I) the cash return of capital or fair market
          value amount, as the case may be, with respect to such Restricted
          Investment (less the cost of disposition, if any) and (II) the initial
          amount of such Restricted Investment, plus (4) to the extent that any
          Unrestricted Subsidiary is redesignated as a Restricted Subsidiary
          after the date of this Indenture, the lesser of (I) the fair market
          value of the Authority's Investment in such Subsidiary as of the date
          of such redesignation or (II) such fair market value as of the date on
          which such Subsidiary was originally designated as an Unrestricted
          Subsidiary.

     (b) So long as no Default has occurred and is continuing or would be caused
thereby, the preceding provisions will not prohibit: (i) the defeasance,
redemption, repurchase or other acquisition of Subordinated Indebtedness with
the net cash proceeds from an incurrence of Permitted Refinancing Indebtedness;
(ii) the payment of any dividend by a Restricted Subsidiary of the Authority to
the holders of its common Equity Interests on a pro rata basis; (iii) the
repurchase, redemption or other acquisition or retirement for value of any
Equity Interests of any Restricted Subsidiary of the Authority held by any


                                       45
                                                       Senior Subordinated Notes

member of the Authority's (or any of its Restricted Subsidiaries') management
pursuant to any management equity subscription agreement or stock option
agreement in effect as of the date of this Indenture; provided that (a) the
aggregate price paid for all such repurchased, redeemed, acquired or retired
Equity Interests shall not exceed $1.0 million in any 12-month period and (b)
the aggregate amount of all such repurchased, redeemed, acquired or retired
Equity Interests shall not in the aggregate exceed $3.0 million; (iv) the
redemption or purchase of Subordinated Indebtedness of the Authority in the
event that the holder of such Subordinated Indebtedness has failed to qualify or
be found suitable or otherwise be eligible by any Gaming Regulatory Authority to
remain a holder of such Subordinated Indebtedness; (v) the redemption,
defeasance, repurchase or other acquisition or retirement of Subordinated
Indebtedness with the net cash proceeds from a substantially concurrent capital
contribution from the Tribe (provided that such capital contribution is not
counted for purposes of Section 4.07(a)(C)(2)); and (vi) any other Restricted
Payments in an amount not to exceed $20.0 million at any one time outstanding.

     (c) The Authority may designate any Restricted Subsidiary to be an
Unrestricted Subsidiary if such designation would not cause a Default; provided
that in no event shall (i) any entity (including any Subsidiary of the Authority
or the Authority or any operating division thereof) engaged in a Principal
Business be transferred to or held by an Unrestricted Subsidiary or (ii) any Key
Project Assets or Gaming Licenses be transferred to an Unrestricted Subsidiary.
In the event of such designation, all outstanding Investments owned by the
Authority and its Restricted Subsidiaries in the Subsidiary so designated will
be deemed to be an Investment made as of the time of such designation and will
reduce the amount available for Restricted Payments under Section 4.07(a) unless
the Investment constitutes a Permitted Investment. All such outstanding
Investments will be deemed to constitute Restricted Payments in an amount equal
to the fair market value of such Investments at the time of such designation.
Such designation will only be permitted if such Restricted Payment would be
permitted at such time and if such Restricted Subsidiary otherwise meets the
definition of an Unrestricted Subsidiary. The Authority may redesignate an
Unrestricted Subsidiary to be a Restricted Subsidiary if such redesignation
would not otherwise cause a Default.

     (d) The amount of all Restricted Payments (other than cash) shall be the
fair market value on the date of the Restricted Payment of the asset(s) or
securities proposed to be transferred or issued by the Authority or such
Restricted Subsidiary, as the case may be, pursuant to the Restricted Payment.
The fair market value of any assets or securities that are required to be valued
by this Section 4.07 shall be determined by the Management Board whose
resolution with respect thereto shall be delivered to the Trustee. Not later
than the date of making any Restricted Payment, the Authority shall deliver to
the Trustee an Officers' Certificate stating that such Restricted Payment is
permitted and setting forth the basis upon which the calculations required by
this Section 4.07 were computed.

Section 4.08.  Dividend and Other Payment Restrictions Affecting Subsidiaries.

     (a) Except as set forth in Section 4.08(b), the Authority will not, and
will not permit any of its Restricted Subsidiaries to, directly or indirectly,
create or permit to exist or become effective any encumbrance or restriction on
the ability of any Restricted Subsidiary to: (i) pay dividends or make any other
distributions on its Capital Stock to the Authority or any of the Authority's
Restricted Subsidiaries, or with respect to any other interest or participation
in, or measured by, its profits, or pay any indebtedness owed to the Authority
or any of the Authority's Restricted Subsidiaries; (ii) make loans or advances
to the Authority or any of the Authority's Restricted Subsidiaries; or (iii)
transfer any of its properties or assets to the Authority or any of the
Authority's Restricted Subsidiaries.

     (b) The provisions of Section 4.08(a) will not apply to encumbrances or
restrictions existing under or by reason of:

     (i)    Existing Indebtedness as in effect on the date of this Indenture and
            any amendments, modifications, restatements, renewals, extensions,
            increases, supplements, refundings, replacements or refinancings
            thereof, provided that such amendments, modifications, restatements,
            renewals, extensions, increases, supplements, refundings,
            replacements or refinancings are no more restrictive, taken as a
            whole, with respect to such dividend and other payment restrictions
            than those contained in such Existing Indebtedness, as in effect on
            the date of this Indenture;

     (ii)   this Indenture and the Senior Subordinated Notes;

     (iii)  the Senior Notes Indenture and the Senior Notes;

     (iv)   the Credit Facilities;

     (v)    applicable law;

     (vi)   any instrument governing Indebtedness or Capital Stock of a Person
            acquired by the Authority or any of its Restricted Subsidiaries as
            in effect at the time of such acquisition (except to the extent such
            Indebtedness was incurred in connection with or in contemplation of
            such acquisition), which encumbrance or restriction is not
            applicable to any Person, or the properties or assets of any Person,
            other than the Person, or the property or assets of the Person, so
            acquired, provided that, in the case of Indebtedness, such
            Indebtedness was permitted by the terms of this Indenture to be
            incurred;

     (vii)  customary non-assignment provisions in leases or other contracts
            entered into in the ordinary course of business and consistent with
            past practices;

     (viii) purchase money obligations (including, without limitation, Capital
            Lease Obligations) for property acquired in the ordinary course of
            business that impose restrictions on the property so acquired of the
            nature described in Section 4.08(a)(iii);

     (ix)   any agreement for the sale or other disposition of a Restricted
            Subsidiary that restricts distributions by such Restricted
            Subsidiary pending its sale or other disposition;

     (x)    Permitted Refinancing Indebtedness, provided that the restrictions
            contained in the agreements governing such Permitted Refinancing
            Indebtedness are no more restrictive, taken as a whole, than those
            contained in the agreements governing the Indebtedness being
            refinanced;

     (xi)   Liens securing Indebtedness otherwise permitted to be incurred
            pursuant to Section 4.12 that limit the right of the Authority or
            any of its Restricted Subsidiaries to dispose of the assets subject
            to such Lien;

     (xii)  provisions with respect to the disposition or distribution of assets
            or property in joint venture agreements and other similar agreements
            entered into in the ordinary course of business; and

     (xiii) restrictions on cash or other deposits or net worth imposed by
            customers under contracts entered into in the ordinary course of
            business.

Section 4.09.  Incurrence of Indebtedness and Issuance of Preferred Stock.

     (a) The Authority will not, and will not permit any of its Subsidiaries to,
directly or indirectly, create, incur, issue, assume, guarantee or otherwise
become directly or indirectly liable, contingently or otherwise, with respect to
(collectively, "incur") any Indebtedness (including Acquired Indebtedness) and
the Authority will not issue any Disqualified Stock and will not permit any of
its Subsidiaries to issue any shares of preferred stock; provided, however, that
the Authority may incur Indebtedness (including Acquired Indebtedness) or issue
shares of Disqualified Stock and the Authority's Subsidiaries may incur
Indebtedness or issue preferred stock if the Fixed Charge Coverage Ratio for the
Authority's most recently ended four full fiscal quarters for which internal
financial statements are available immediately preceding the date on which such
additional Indebtedness is incurred would have been at least 2.0 to 1 determined
on a pro forma basis (including a pro forma application of the net proceeds
therefrom), as if the additional Indebtedness had been incurred at the beginning
of such four-quarter period. Notwithstanding the foregoing, the Authority will
not issue any Disqualified Stock or any type of Capital Stock that would violate
IGRA.

     (b) So long as no Default or Event of Default shall have occurred and be
continuing, or would be caused thereby, Section 4.09(a) will not prohibit the
incurrence of any of the following items of Indebtedness:

     (i)    the incurrence by the Authority or its Restricted Subsidiaries of
            Indebtedness and letters of credit pursuant to Credit Facilities;
            provided that the aggregate principal amount of all such
            Indebtedness and letters of credit outstanding under all Credit
            Facilities, after giving effect to such incurrence (with letters of
            credit being deemed to have a principal amount equal to the maximum
            potential liability of the Authority thereunder), does not exceed
            $500.0 million less the aggregate amount of all Net Proceeds of
            Asset Sales applied by the Authority or any of its Restricted
            Subsidiaries since the date of this Indenture to repay Indebtedness
            under Credit Facilities permitted under Section 4.10;

     (ii)   the incurrence by the Authority and its Restricted Subsidiaries of
            the Existing Indebtedness;

     (iii)  the incurrence by the Authority of Indebtedness represented by the
            Senior Subordinated Notes and the Senior Subordinated Exchange
            Notes;

     (iv)   the incurrence by the Authority of Indebtedness represented by the
            Senior Notes and the Senior Exchange Notes;

     (v)    the incurrence by the Authority or any of its Restricted
            Subsidiaries of Indebtedness represented by Capital Lease
            Obligations, mortgage financings or purchase money obligations, in
            each case incurred for the purpose of financing all or any part of
            the purchase price of furniture, fixtures, equipment or similar
            assets used or useful in the business of the Authority or such
            Restricted Subsidiary not to exceed 100% of the lesser of cost or
            fair market value of the assets financed and, in an aggregate
            principal amount under this clause (v) not to exceed $25.0 million
            at any time outstanding;

     (vi)   the incurrence by the Authority or any of its Restricted
            Subsidiaries of Permitted Refinancing Indebtedness in exchange for,
            or the net proceeds of which are used to refund, refinance, renew,
            extend, defease or replace Indebtedness that was permitted by


                                       48

            this Indenture to be incurred under Section 4.09(a) or clauses (i),
            (ii) (other than the Junior Subordinated Notes), (iii), (iv) or (v)
            of Section 4.09(b);

     (vii)  the incurrence by the Authority or any of its Restricted
            Subsidiaries of Hedging Obligations that are incurred for the
            purpose of fixing or hedging interest rate risk with respect to any
            floating rate Indebtedness that is permitted by the terms of this
            Indenture to be outstanding;

     (viii) the guarantee by the Authority or any of its Restricted Subsidiaries
            of any Indebtedness of the Authority or any of its Restricted
            Subsidiaries that was permitted to be incurred by another provision
            of this Section 4.09;

     (ix)   the incurrence by a Wholly Owned Restricted Subsidiary of
            Indebtedness owed to another Wholly Owned Restricted Subsidiary or
            to the Authority; provided that if at any time any such Wholly Owned
            Restricted Subsidiary ceases to be a Wholly Owned Restricted
            Subsidiary, any such Indebtedness shall be deemed to be an
            incurrence of Indebtedness for the purposes of this Section 4.09;

     (x)    the incurrence by the Authority or any of its Restricted
            Subsidiaries of additional Indebtedness in an aggregate principal
            amount (or accreted value, as applicable) at any time outstanding,
            including all Permitted Refinancing Indebtedness incurred to refund,
            refinance or replace any Indebtedness incurred pursuant to this
            clause (x), not to exceed $25.0 million; or

     (xi)   the incurrence by the Authority's Unrestricted Subsidiaries of
            Non-Recourse Debt, provided, however, that if any such Indebtedness
            ceases to be Non-Recourse Debt of an Unrestricted Subsidiary, such
            event shall be deemed to constitute an incurrence of Indebtedness by
            a Restricted Subsidiary of the Authority that was not permitted by
            this clause (xi).

     For purposes of determining compliance with this Section 4.09 in the event
that an item of proposed Indebtedness meets the criteria of more than one of the
categories of Indebtedness described in clauses (i) through (xi) above or is
entitled to be incurred pursuant to Section 4.09(a), the Authority shall, in its
sole discretion, classify such item of Indebtedness on the date of its
incurrence in any manner that complies with this Section 4.09.

Section 4.10.  Asset Sales.

     (a) The Authority will not, and will not permit any of its Restricted
Subsidiaries to, consummate an Asset Sale unless: (i) the Authority (or its
Restricted Subsidiary, as the case may be) receives consideration at the time of
such Asset Sale at least equal to the fair market value (as determined in good
faith by the Management Board and evidenced by a resolution set forth in an
Officers' Certificate delivered to the Trustee) of the assets sold or otherwise
disposed of; and (ii) except in the case of a Permitted Asset Swap, at least 75%
of the consideration therefor received by the Authority or such Restricted
Subsidiary is in the form of cash. For purposes of this provision, each of the
following shall be deemed to be cash: (A) any liabilities that would appear on
the Authority's or such Restricted Subsidiary's balance sheet prepared in
accordance with GAAP (other than contingent liabilities and liabilities that are
by their terms subordinated to the Senior Subordinated Notes or any guarantee
thereof) that are assumed by the transferee of any such assets pursuant to a
customary novation agreement that releases the Authority or such Restricted
Subsidiary from further liability; and (B) any securities, notes or other
obligations received by the Authority or any such Restricted Subsidiary from
such transferee that


                                       49

are converted by the Authority or such Restricted Subsidiary into cash (to the
extent of the cash received) within 30 days of the receipt thereof, provided,
however, that the Authority will not be permitted to make any Asset Sale of Key
Project Assets.

     (b) Within 360 days after the receipt of any Net Proceeds from an Asset
Sale, the Authority may apply such Net Proceeds, at its option, to: (i) repay
permanently term Indebtedness under Credit Facilities of the Authority or any
Restricted Subsidiary; (ii) repay revolving credit Indebtedness under Credit
Facilities and correspondingly permanently reduce commitments with respect
thereto; (iii) acquire a majority of the assets of, or a majority of the Voting
Stock of, an entity engaged in the Principal Business or a Related Business;
(iv) make capital expenditures or acquire other long-term assets that are used
or useful in the Principal Business or a Related Business; (v) make an
investment in the Principal Business or a Related Business or in tangible
long-term assets used or useful in the Principal Business or a Related Business;
or (vi) reduce permanently Indebtedness (including the Senior Notes) that is not
Subordinated Indebtedness.

     Pending the final application of any such Net Proceeds, the Authority may
temporarily reduce revolving credit borrowings or otherwise invest such Net
Proceeds in any manner that is not prohibited by this Indenture.

     (c) Any Net Proceeds from Asset Sales that are not applied or invested as
provided in Section 4.10(b) will be deemed to constitute "Excess Proceeds." When
the aggregate amount of Excess Proceeds exceeds $15.0 million, the Authority
will make an Asset Sale Offer to all Holders of Senior Subordinated Notes and
all holders of other Indebtedness containing provisions similar to those set
forth in this Indenture with respect to offers to purchase or redeem with the
proceeds of sales of assets to purchase the maximum principal amount of Senior
Subordinated Notes and such other Indebtedness that may be purchased out of the
Excess Proceeds. The offer price in any Asset Sale Offer will be equal to 100%
of the principal amount plus accrued and unpaid interest and Additional
Interest, if any, to the date of purchase and will be payable in cash, in
accordance with the procedures set forth in this Indenture and such other
Indebtedness. To the extent that any Excess Proceeds remain after consummation
of an Asset Sale Offer, the Authority may use such Excess Proceeds for any
purpose not otherwise prohibited by this Indenture. If the aggregate principal
amount of Senior Subordinated Notes and such other Indebtedness tendered into
such Asset Sale Offer surrendered by holders thereof exceeds the amount of
Excess Proceeds, the Trustee shall select the Senior Subordinated Notes and such
other Indebtedness (to the extent that such other Indebtedness permits such
selection) to be purchased on a pro rata basis. Upon completion of such offer to
purchase, the amount of Excess Proceeds shall be reset at zero.

Section 4.11.  Transactions with Affiliates.

     (a) The Authority will not, and the Authority will not permit any of its
Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or
otherwise dispose of any of its properties or assets to, or purchase any
property or assets from, or enter into or make or amend any transaction,
contract, agreement, understanding, loan, advance or guarantee with, or for the
benefit of, any Affiliate (each of the foregoing, an "Affiliate Transaction"),
unless: (i) such Affiliate Transaction is on terms that are no less favorable to
the Authority or the relevant Restricted Subsidiary than those that would have
been obtained in a comparable transaction by the Authority or such Restricted
Subsidiary with an unrelated Person; and (ii) the Authority delivers to the
Trustee: (A) with respect to any Affiliate Transaction or series of related
Affiliate Transactions involving aggregate consideration in excess of $5.0
million, a resolution of the Management Board set forth in an Officers'
Certificate certifying that such Affiliate Transaction complies with this
Section 4.11 and that such Affiliate Transaction has been approved by a majority
of the disinterested members of the Management Board; and (B) with respect to
any Affiliate Transaction or series of related Affiliate Transactions involving
aggregate consideration in

excess of $10.0 million, an opinion as to the fairness to the Authority or such
Restricted Subsidiary of such Affiliate Transaction from a financial point of
view issued by an accounting, appraisal or investment banking firm of national
standing.

     (b) The following items shall not be deemed to be Affiliate Transactions
and, therefore, will not be subject to the provisions of Section 4.11(a): (i)
any employment agreement or arrangement entered into by the Authority or any of
its Restricted Subsidiaries in the ordinary course of business and consistent
with the past practice of the Authority or such Restricted Subsidiary; (ii)
transactions between or among the Authority and/or its Restricted Subsidiaries;
(iii) payment of reasonable Management Board fees to members of the Management
Board; (iv) transactions with Persons in whom the Authority owns any Equity
Interests, so long as the remaining equity holders of such Person are not
Affiliates of the Authority or any of its Subsidiaries; (v) Government Service
Payments; (vi) transactions pursuant to the Development Services Agreement, the
Relinquishment Agreement and the Side Letters; (vii) Restricted Payments or
Permitted Investments that are made in compliance with the provisions of Section
4.07; and (viii) contractual arrangements existing on the date of this Indenture
and renewals, extensions and any modifications thereof that are not materially
adverse to Holders.

Section 4.12.  Liens.

     The Authority will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, create, incur, assume or otherwise
cause or suffer to exist or become effective any Lien of any kind (other than
Permitted Liens) upon any of its property or assets or any proceeds therefrom,
which secure either (i) Subordinated Indebtedness, unless the Senior
Subordinated Notes are secured by a Lien on such property assets or proceeds,
which Lien is senior in priority to the Liens securing such Subordinated
Indebtedness or (ii) pari passu Indebtedness, unless the Senior Subordinated
Notes are equally and ratably secured with the Liens securing such pari passu
Indebtedness.

Section 4.13.  Line of Business.

     The Authority shall not, and shall not permit any of its Restricted
Subsidiaries to, engage in any business other than the Principal Business or a
Related Business.

Section 4.14.  Existence of the Authority and Maintenance of the Lease.

     (a) The Authority shall, and shall cause each of its Restricted
Subsidiaries to, do or cause to be done all things necessary to preserve and
keep in full force and effect their respective existence, in accordance with
their respective organizational documents and their respective rights
(contractual, charter and statutory), licenses and franchises; provided,
however, that neither the Authority nor any Restricted Subsidiary shall be
required to preserve, with respect to itself, any license, right or franchise
and, with respect to its Restricted Subsidiaries, any such existence, license,
right or franchise, if its Management Board or Board of Directors, or other
governing body or officers authorized to make such determination, as the case
may be, shall determine that the preservation thereof is no longer desirable in
the conduct of the business of the Authority or any Restricted Subsidiary, and
that the loss thereof is not adverse in any material respect to the Holders.

     (b) The Authority shall do, or cause to be done, all things necessary to
perform any material covenants set forth in the Lease in order to keep the Lease
in full force and effect.

     (a) If a Change of Control occurs, each Holder of the Senior Subordinated
Notes will have the right to require the Authority to repurchase all or any part
(equal to $1,000 or an integral multiple thereof) of that Holder's Senior
Subordinated Notes pursuant to a Change of Control Offer. In the Change of
Control Offer, the Authority will offer a Change of Control Payment in cash
equal to 101% of the aggregate principal amount of Senior Subordinated Notes
repurchased plus accrued and unpaid interest and Additional Interest, if any,
thereon, to the date of purchase.

     (b) Within 20 Business Days following any Change of Control, the Authority
will mail a notice to each Holder (and, unless the Trustee makes the mailing on
behalf of the Authority, to the Trustee) describing the transaction or
transactions that constitute the Change of Control and offering to repurchase
Senior Subordinated Notes on the Change of Control Payment Date specified in
such notice, pursuant to the procedures required by this Indenture and described
in such notice. If the Authority wishes the Trustee to do the mailing, it will
give the Trustee adequate prior notice so that the Trustee may do so. The
Authority will comply with the requirements of Rule 14e-1 under the Exchange Act
and any other securities laws and regulations thereunder to the extent such laws
and regulations are applicable in connection with the repurchase of the Senior
Subordinated Notes as a result of a Change of Control.

     (c) On the Change of Control Payment Date, the Authority will, to the
extent lawful: (i) accept for payment all Senior Subordinated Notes or portions
thereof properly tendered pursuant to the Change of Control Offer; (ii) deposit
with the Paying Agent an amount equal to the Change of Control Payment in
respect of all Senior Subordinated Notes or portions thereof so tendered; and
(iii) deliver or cause to be delivered to the Trustee the Senior Subordinated
Notes so accepted together with an Officers' Certificate stating the aggregate
principal amount of Senior Subordinated Notes or portions thereof being
purchased by the Authority.

     (d) The Paying Agent will promptly mail to each Holder of Senior
Subordinated Notes so tendered the Change of Control Payment for such Senior
Subordinated Notes, and the Trustee will promptly authenticate and mail (or
cause to be transferred by book entry) to each Holder a new Senior Subordinated
Note equal in principal amount to any unpurchased portion of the Senior
Subordinated Notes surrendered, if any; provided that each such new Senior
Subordinated Note will be in a principal amount of $1,000 or an integral
multiple thereof. The Authority will notify the Trustee and will instruct the
Trustee to notify the Holders of the results of the Change of Control Offer on
or as soon as practicable after the Change of Control Payment Date.

     (e) Notwithstanding anything to the contrary in this Section 4.15, the
Authority shall not be required to make a Change of Control Offer upon a Change
of Control if a third party makes the Change of Control Offer in the manner, at
the times and otherwise in compliance with the requirements set forth in this
Section 4.15 and Section 3.10 hereof and all other provisions of this Indenture
applicable to a Change of Control Offer made by the Authority and purchases all
Senior Subordinated Notes validly tendered and not withdrawn under such Change
of Control Offer.

Section 4.16.  No Senior Subordinated Debt.

     Notwithstanding the provisions of Section 4.09 hereof, (i) the Authority
shall not incur any Indebtedness that is subordinate or junior in right of

to the Senior Subordinated Notes, and (ii) no Subsidiary Guarantor shall incur
any Indebtedness that is subordinated or junior in right of payment to any
Senior Subsidiary Guarantees of Senior Indebtedness and senior in any respect in
right of payment to the Senior Subordinated Subsidiary Guarantees.

Owned Restricted Subsidiary and (b) the cash Net Proceeds from such transfer,
conveyance, sale, lease or other disposition are applied in accordance with

Subordinated Notes that consent, waive or agree to amend in the time frame set
forth in the solicitation documents relating to such consent, waiver or
agreement.

Section 4.20.  Senior Subordinated Subsidiary Guarantees.

          force and effect or any Subsidiary Guarantor, or any Person acting on
          behalf of any Subsidiary Guarantor, shall deny or disaffirm its
          obligations under such Subsidiary Guarantor's Senior Subordinated
          Subsidiary Guarantee; or

     (m)  failure by the Tribe to comply with the provisions of Article 11 for

          Senior Subordinated Notes then outstanding voting as a single class.

Section 6.02.  Acceleration.

     If any Event of Default (other than an Event of Default specified in clause
(g) or (h) of Section 6.01 hereof with respect to the Authority, any Restricted
Subsidiary that is a Significant Subsidiary or any group of Restricted
Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary)
occurs and is continuing, the Trustee or the Holders of at least 25% in
principal amount of the then outstanding Senior Subordinated Notes may declare
all the Senior Subordinated Notes to be due and payable immediately. Upon any
such declaration, the Senior Subordinated Notes shall become due and payable
immediately. Notwithstanding the foregoing, if an Event of Default specified in
clause (g) or (h) of Section 6.01 hereof occurs with respect to the Authority,
any of its Restricted Subsidiaries that are Significant Subsidiaries or any
group of Restricted Subsidiaries that, taken as a whole, would constitute a
Significant Subsidiary, all outstanding Senior Subordinated Notes shall be due
and payable immediately without further action or notice. The Holders of a
majority in aggregate principal amount of the then outstanding Senior
Subordinated Notes by written notice to the Trustee may on behalf of all of the
Holders rescind an acceleration and its consequences if the rescission would not
conflict with any judgment or decree and if all existing Events of Default
(except nonpayment of principal, interest or premium that has become due solely
because of the acceleration) have been cured or waived.

     If an Event of Default occurs on or after January 1, 2004 by reason of any
willful action (or inaction) taken (or not taken) by or on behalf of the
Authority with the intention of avoiding payment of the premium that the
Authority would have had to pay if the Authority then had elected to redeem the
Senior Subordinated Notes pursuant to Section 3.07 hereof, then, upon
acceleration of the Senior Subordinated Notes, an equivalent premium shall also
become and be immediately due and payable, to the extent permitted by law,
anything in this Indenture or in the Senior Subordinated Notes to the contrary
notwithstanding. If an Event of Default occurs prior to January 1, 2004 by
reason of any willful action (or inaction) taken (or not taken) by or on behalf
of the Authority with the intention of avoiding the prohibition on redemption of
the Senior Subordinated Notes prior to such date, then, upon acceleration of the
Senior Subordinated Notes, an additional premium shall also become and be
immediately due and payable in an amount, for each of the years beginning on
January 1 of the years set forth below, as set forth below (expressed as a
percentage of the principal amount of the Senior Subordinated Notes on the date
of payment that would otherwise be due but for the provisions of this sentence):

Section 6.03.  Other Remedies.

     If an Event of Default occurs and is continuing, the Trustee may pursue any
available remedy to collect the payment of principal, premium, if any, and
interest on the Senior Subordinated Notes or to enforce the performance of any
provision of the Senior Subordinated Notes or this Indenture.

     The Trustee may maintain a proceeding even if it does not possess any of
the Senior Subordinated Notes or does not produce any of them in the proceeding.
A delay or omission by the Trustee or any Holder of a Senior Subordinated Note
in exercising any right or remedy accruing upon an Event of Default shall not
impair the right or remedy or constitute a waiver of or acquiescence in the
Event of Default. All remedies are cumulative to the extent permitted by law.

Section 6.04.  Waiver of Past Defaults.

     Holders of not less than a majority in aggregate principal amount of the
then outstanding Senior Subordinated Notes by notice to the Trustee may on
behalf of the Holders of all of the Senior Subordinated Notes waive an existing
Default or Event of Default and its consequences hereunder, except a continuing
Default or Event of Default in the payment of the principal of, premium and
Additional Interest , if any, or interest on, the Senior Subordinated Notes
(including in connection with an offer to purchase) (provided, however, that the
Holders of a majority in aggregate principal amount of the then outstanding
Senior Subordinated Notes may rescind an acceleration and its consequences,
including any related payment default that resulted from such acceleration).
Upon any such waiver, such Default shall cease to exist, and any Event of
Default arising therefrom shall be deemed to have been cured for every purpose
of this Indenture; but no such waiver shall extend to any subsequent or other
Default or impair any right consequent thereon.

Section 6.05.  Control by Majority.

     Holders of a majority in principal amount of the then outstanding Senior
Subordinated Notes may direct the time, method and place of conducting any
proceeding for exercising any remedy available to the Trustee or exercising any
trust or power conferred on it. However, the Trustee may refuse to follow any
direction that conflicts with law or this Indenture that the Trustee determines
may be unduly prejudicial to the rights of other Holders of Senior Subordinated
Notes or that may involve the Trustee in personal liability.

Section 6.06.  Limitation on Suits.

     A Holder of a Senior Subordinated Note may pursue a remedy with respect to
this Indenture or the Senior Subordinated Notes only if:

     (a) the Holder of a Senior Subordinated Note gives to the Trustee written
notice of a continuing Event of Default;


                                       59

     (b) the Holders of at least 25% in principal amount of the then outstanding
Senior Subordinated Notes make a written request to the Trustee to pursue the
remedy;

     (c) such Holder of a Senior Subordinated Note or Holders of Senior
Subordinated Notes offer and, if requested, provide to the Trustee indemnity
satisfactory to the Trustee against any loss, liability or expense;

     (d) the Trustee does not comply with the request within 60 days after
receipt of the request and the offer and, if requested, the provision of
indemnity; and

     (e) during such 60-day period the Holders of a majority in principal amount
of the then outstanding Senior Subordinated Notes do not give the Trustee a
direction inconsistent with the request.

     A Holder of a Senior Subordinated Note may not use this Indenture to
prejudice the rights of another Holder of a Senior Subordinated Note or to
obtain a preference or priority over another Holder of a Senior Subordinated
Note.

Section 6.07.  Rights of Holders of Senior Subordinated Notes to Receive
               Payment.

     Notwithstanding any other provision of this Indenture, the right of any
Holder of a Senior Subordinated Note to receive payment of principal, premium
and Additional Interest, if any, and interest on the Senior Subordinated Note,
on or after the respective due dates expressed in the Senior Subordinated Note
(including in connection with an offer to purchase), or to bring suit for the
enforcement of any such payment on or after such respective dates, shall not be
impaired or affected without the consent of such Holder.

Section 6.08.  Collection Suit by Trustee.

     If an Event of Default specified in Section 6.01(a) or (b) occurs and is
continuing, the Trustee is authorized to recover judgment in its own name and as
trustee of an express trust against the Authority for the whole amount of
principal of, premium and Additional Interest, if any, and interest remaining
unpaid on the Senior Subordinated Notes and interest on overdue principal and,
to the extent lawful, interest and such further amount as shall be sufficient to
cover the costs and expenses of collection, including the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel.

Section 6.09.  Trustee May File Proofs of Claim.

     The Trustee is authorized to file such proofs of claim and other papers or
documents as may be necessary or advisable in order to have the claims of the
Trustee (including any claim for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel) and the
Holders of the Senior Subordinated Notes allowed in any judicial proceedings
relative to the Authority (or any other obligor upon the Senior Subordinated
Notes), its creditors or its property and shall be entitled and empowered to
collect, receive and distribute any money or other property payable or
deliverable on any such claims and any custodian in any such judicial proceeding
is hereby authorized by each Holder to make such payments to the Trustee, and in
the event that the Trustee shall consent to the making of such payments directly
to the Holders, to pay to the Trustee any amount due to it for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, and any other amounts due the Trustee under Section 7.07 hereof. To
the extent that the payment of any such compensation, expenses, disbursements
and advances of the Trustee, its agents and counsel, and any other amounts due
the Trustee under Section 7.07 hereof out of the estate in any such proceeding,
shall be denied for any reason, payment of the same shall be

secured by a Lien on, and shall be paid out of, any and all distributions,
dividends, money, securities and other properties that the Holders may be
entitled to receive in such proceeding whether in liquidation or under any plan
of reorganization or arrangement or otherwise. Nothing herein contained shall be
deemed to authorize the Trustee to authorize or consent to or accept or adopt on
behalf of any Holder any plan of reorganization, arrangement, adjustment or
composition affecting the Senior Subordinated Notes or the rights of any Holder,
or to authorize the Trustee to vote in respect of the claim of any Holder in any
such proceeding.

     If the Trustee collects any money pursuant to this Article, it shall pay
out the money in the following order:

          First:  to the Trustee, its agents and attorneys for amounts due under
     Section 7.07 hereof, including payment of all compensation, expense and
     liabilities incurred, and all advances made, by the Trustee and the costs

          Second: to Holders of Senior Subordinated Notes for amounts due and
     unpaid on the Senior Subordinated Notes for principal, premium and

Section 6.11.  Undertaking for Costs.

     In any suit for the enforcement of any right or remedy under this Indenture
or in any suit against the Trustee for any action taken or omitted by it as a
Trustee, a court in its discretion may require the filing by any party litigant
in the suit of an undertaking to pay the costs of the suit, and the court in its
discretion may assess reasonable costs, including reasonable attorneys' fees,
against any party litigant in the suit, having due regard to the merits and good
faith of the claims or defenses made by the party litigant. This Section does
not apply to a suit by the Trustee, a suit by a Holder of a Senior Subordinated

affairs.

     (b) Except during the continuance of an Event of Default:

     conclusively rely, as to the truth of the statements and the correctness of
     the opinions expressed therein, upon certificates or opinions furnished to
     the Trustee and conforming to the requirements of this Indenture. However,

Trustee is entitled to rely exclusively on Officers' Certificates).

opinion, report, notice, request, direction, consent, order, bond, debenture,
note, other evidence of indebtedness or other paper or document, but the Trustee

incurred by it arising out of or in connection with the acceptance or
administration of its duties under this Indenture, including the costs and
expenses of enforcing this Indenture against the Authority (including this
Section 7.07) and defending itself against any claim (whether asserted by the
Authority or any Holder or any other person) or liability in connection with the
exercise or performance of any of its powers or duties hereunder, except to the
extent any such loss, liability or expense may be attributable to its negligence
or bad faith. The Trustee shall notify the Authority promptly of any claim for
which it may seek indemnity. Failure by the Trustee to so notify the Authority
shall not relieve the Authority of its obligations hereunder. The Authority
shall defend the claim and the Trustee shall cooperate in the defense. The
Trustee may have separate counsel and the Authority shall pay the reasonable
fees and expenses of such counsel. The Authority need not pay for any settlement
made without its consent, which consent shall not be unreasonably withheld.

     The obligations of the Authority under this Section 7.07 shall survive the
satisfaction and discharge of this Indenture.

     To secure the Authority's payment obligations in this Section 7.07, the
Trustee shall have a Lien prior to the Senior Subordinated Notes on all money or
property held or collected by the Trustee, except that held in trust to pay
principal and interest on particular Senior Subordinated Notes. Such Lien shall
survive the satisfaction and discharge of this Indenture.

     When the Trustee incurs expenses or renders services after an Event of
Default specified in Section 6.01(g) or (h) hereof occurs, the expenses and the
compensation for the services (including the fees and expenses of its agents and
counsel) are intended to constitute expenses of administration under any
Bankruptcy Law.

Section 7.08.  Replacement of Trustee.

     A resignation or removal of the Trustee and appointment of a successor
Trustee shall become effective only upon the successor Trustee's acceptance of
appointment as provided in this Section.

<PAGE>
 
     The Trustee may resign in writing at any time and be discharged from the
trust hereby created by so notifying the Authority. The Holders of a majority in
principal amount of the then outstanding Senior Subordinated Notes may remove
the Trustee by so notifying the Trustee and the Authority in writing. The
Authority may remove the Trustee if:

     (a) the Trustee fails to comply with Section 7.10 hereof;

     (b) the Trustee is adjudged a bankrupt or an insolvent or an order for
relief is entered with respect to the Trustee under any Bankruptcy Law;

     (c) a custodian or public officer takes charge of the Trustee or its
property; or

     (d) the Trustee becomes incapable of acting.

     If the Trustee resigns or is removed or if a vacancy exists in the office
of Trustee for any reason, the Authority shall promptly appoint a successor
Trustee. Within one year after the successor Trustee takes office, the Holders
of a majority in principal amount of the then outstanding Senior Subordinated
Notes may appoint a successor Trustee to replace the successor Trustee appointed
by the Authority.

     If any Gaming Regulatory Authority requires a Trustee to be approved,
licensed or qualified and the Trustee fails or declines to do so, such approval,
license or qualification shall be obtained upon the request of, and at the
expense of, the Authority unless the Trustee declines to do so, or, if the
Trustee's relationship with either the Authority may, in the Authority's
discretion, jeopardize any material gaming license or franchise or right or
approval granted thereto, the Trustee shall resign, and, in addition, the
Trustee may at its option resign if the Trustee in its sole discretion
determines not to be so approved, licensed or qualified.

     If a successor Trustee does not take office within 60 days after the
retiring Trustee resigns or is removed, the retiring Trustee, the Authority, or
the Holders of at least a majority in principal amount of the then outstanding
Senior Subordinated Notes may petition any court of competent jurisdiction for
the appointment of a successor Trustee.

     If the Trustee, after written request by the Holders of a majority in
principal amount of the then outstanding Senior Subordinated Notes, fails to
comply with Section 7.10, such Holder may petition any court of competent
jurisdiction for the removal of the Trustee and the appointment of a successor
Trustee.

     A successor Trustee shall deliver a written acceptance of its appointment
to the retiring Trustee and to the Authority. Thereupon, the resignation or
removal of the retiring Trustee shall become effective, and the successor
Trustee shall have all the rights, powers and duties of the Trustee under this
Indenture. The successor Trustee shall mail a notice of its succession to
Holders. The retiring Trustee shall promptly transfer all property held by it as
Trustee to the successor Trustee, provided all sums owing to the Trustee
hereunder have been paid and subject to the Lien provided for in Section 7.07
hereof. Notwithstanding replacement of the Trustee pursuant to this Section
7.08, the Authority's obligations under Section 7.07 hereof shall continue for
the benefit of the retiring Trustee.

Section 7.09.  Successor Trustee by Merger, etc.

     If the Trustee consolidates, merges or converts into, or transfers all or
substantially all of its corporate trust business (including the trust created
by this Indenture) to, another corporation, the successor corporation without
any further act shall be the successor Trustee.

Section 7.10.  Eligibility; Disqualification.

     There shall at all times be a Trustee hereunder that is a corporation
organized and doing business under the laws of the United States of America or
of any state thereof that is authorized under such laws to exercise corporate
trustee power, that is subject to supervision or examination by federal or state
authorities and that has, or together with all of its Subsidiaries and parent
entities has, a combined capital and surplus of at least $100 million as set
forth in its most recent published annual report of condition.

     This Indenture shall always have a Trustee who satisfies the requirements
of TIAss.310(a)(1), (2) and (5). The Trustee is subject to TIAss.310(b).

Section 7.11.  Preferential Collection of Claims Against Authority.

     The Trustee is subject to TIA ss. 311(a), excluding any creditor
relationship listed in TIA ss. 311(b). A Trustee who has resigned or been
removed shall be subject to TIA ss. 311(a) to the extent indicated therein.

                    LEGAL DEFEASANCE AND COVENANT DEFEASANCE

Section 8.01.  Option to Effect Legal Defeasance or Covenant Defeasance.

     The Authority may, at the option of its Management Board evidenced by a
resolution set forth in an Officers' Certificate, at any time, elect to have
either Section 8.02 or 8.03 hereof be applied to all outstanding Senior
Subordinated Notes upon compliance with the conditions set forth below in this
Article 8.

Section 8.02.  Legal Defeasance and Discharge.

     Upon the Authority's exercise under Section 8.01 hereof of the option
applicable to this Section 8.02, the Authority shall, subject to the
satisfaction of the conditions set forth in Section 8.04 hereof, be deemed to
have been discharged from its obligations with respect to all outstanding Senior
Subordinated Notes on the date the conditions set forth below are satisfied
(hereinafter, "Legal Defeasance"). For this purpose, Legal Defeasance means that
the Authority shall be deemed to have paid and discharged the entire
Indebtedness represented by the outstanding Senior Subordinated Notes, which
shall thereafter be deemed to be "outstanding" only for the purposes of Section
8.05 hereof and the other Sections of this Indenture referred to in (a) and (b)
below, and to have satisfied all its other obligations under such Senior
Subordinated Notes and this Indenture (and the Trustee, on demand of and at the
expense of the Authority, shall execute proper instruments acknowledging the
same), except for the following provisions which shall survive until otherwise
terminated or discharged hereunder: (a) the rights of Holders of outstanding
Senior Subordinated Notes to receive solely from the trust fund described in
Section 8.04 hereof, and as more fully set forth in such Section, payments in
respect of the principal of, premium, if any, and interest on such Senior
Subordinated Notes when such payments are due, (b) the Authority's obligations
with respect to such Senior Subordinated Notes under Article 2 and Section 4.02
hereof, (c) the rights, powers, trusts, duties and immunities of the Trustee
hereunder and the Authority's obligations in connection therewith and (d) this
Article 8. Subject to compliance with this Article 8, the Authority may exercise
its option under this Section 8.02 notwithstanding the prior exercise of its
option under Section 8.03 hereof.

Section 8.03.  Covenant Defeasance.

     Upon the Authority's exercise under Section 8.01 hereof of the option
applicable to this Section 8.03, the Authority shall, subject to the
satisfaction of the conditions set forth in Section 8.04 hereof, be released
from its obligations under the covenants contained in Sections 4.07, 4.08, 4.09,
4.10, 4.11, 4.12, 4.13, 4.14(b), 4.15, 4.16, 4.17, 4.18, 4.20, 4.21, 4.22, 4.23,
4.24, 4.25 and 4.27 hereof and Section 5.01 hereof with respect to the
outstanding Senior Subordinated Notes on and after the date the conditions set
forth in Section 8.04 are satisfied (hereinafter, "Covenant Defeasance"), and
the Senior Subordinated Notes shall thereafter be deemed not "outstanding" for
the purposes of any direction, waiver, consent or declaration or act of Holders
(and the consequences of any thereof) in connection with such covenants, but
shall continue to be deemed "outstanding" for all other purposes hereunder (it
being understood that such Senior Subordinated Notes shall not be deemed
outstanding for accounting purposes). For this purpose, Covenant Defeasance
means that, with respect to the outstanding Senior Subordinated Notes, the
Authority may omit to comply with and shall have no liability in respect of any
term, condition or limitation set forth in any such covenant, whether directly
or indirectly, by reason of any reference elsewhere herein to any such covenant
or by reason of any reference in any such covenant to any other provision herein
or in any other document and such omission to comply shall not constitute a
Default or an Event of Default under Section 6.01 hereof, but, except as
specified above, the remainder of this Indenture and such Senior Subordinated
Notes shall be unaffected thereby. In addition, upon the Authority's exercise
under Section 8.01 hereof of the option applicable to this Section 8.03 hereof,
subject to the satisfaction of the conditions set forth in Section 8.04 hereof,
Sections 6.01(c) through 6.01(f) and Sections 6.01(i) through 6.01(m) hereof
shall not constitute Events of Default.

Section 8.04.  Conditions to Legal or Covenant Defeasance.

     The following shall be the conditions to the application of either Section
8.02 or 8.03 hereof to the outstanding Senior Subordinated Notes:

     In order to exercise either Legal Defeasance or Covenant Defeasance:

     (a) the Authority must irrevocably deposit with the Trustee, in trust, for
the benefit of the Holders, cash in United States dollars, non-callable
Government Securities, or a combination thereof, in such amounts as will be
sufficient, in the opinion of a nationally recognized firm of independent public
accountants, to pay the principal of, premium and Additional Interest, if any,
and interest on the outstanding Senior Subordinated Notes on the stated date for
payment thereof or on the applicable redemption date, as the case may be;

     (b) in the case of an election under Section 8.02 hereof, the Authority
shall have delivered to the Trustee an Opinion of Counsel in the United States
reasonably acceptable to the Trustee confirming that (A) the Authority has
received from, or there has been published by, the Internal Revenue Service a
ruling or (B) since the date of this Indenture, there has been a change in the
applicable federal income tax law, in either case to the effect that, and based
thereon such Opinion of Counsel shall confirm that, the Holders of the
outstanding Senior Subordinated Notes will not recognize income, gain or loss
for federal income tax purposes as a result of such Legal Defeasance and will be
subject to federal income tax on the same amounts, in the same manner and at the
same times as would have been the case if such Legal Defeasance had not
occurred;

     (c) in the case of an election under Section 8.03 hereof, the Authority
shall have delivered to the Trustee an Opinion of Counsel in the United States
reasonably acceptable to the Trustee confirming that the Holders of the
outstanding Senior Subordinated Notes will not recognize income, gain or loss
for federal income tax purposes as a result of such Covenant Defeasance and will
be subject to federal

income tax on the same amounts, in the same manner and at the same times as
would have been the case if such Covenant Defeasance had not occurred;

     (d) no Default or Event of Default shall have occurred and be continuing on
the date of such deposit (other than a Default or Event of Default resulting
from the incurrence of Indebtedness all or a portion of the proceeds of which
will be used to defease the Senior Subordinated Notes pursuant to this Article 8
concurrently with such incurrence) or insofar as Sections 6.01(g) or 6.01(h)
hereof is concerned, at any time in the period ending on the 91st day after the
date of deposit;

     (e) such Legal Defeasance or Covenant Defeasance shall not result in a
breach or violation of, or constitute a default under, any material agreement or
instrument (other than this Indenture) to which the Authority or any of its
Restricted Subsidiaries is a party or by which the Authority or any of its
Restricted Subsidiaries is bound;

     (f) the Authority must have delivered to the Trustee an Opinion of Counsel
(which may be subject to customary exceptions) to the effect that after the 91st
day following the deposit, the trust funds will not be subject to the effect of
any applicable bankruptcy, insolvency, reorganization or similar laws affecting
creditors' rights generally;

     (g) the Authority shall have delivered to the Trustee an Officers'
Certificate stating that the deposit was not made by the Authority with the
intent of preferring the Holders over any other creditors of the Authority or
with the intent of defeating, hindering, delaying or defrauding any creditors of
the Authority or others; and

     (h) the Authority shall have delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that all conditions
precedent provided for or relating to the Legal Defeasance or the Covenant
Defeasance have been complied with.

Section 8.05.  Deposited Money and Government Securities to be Held in Trust;
               Other Miscellaneous Provisions.

     Subject to Section 8.06 hereof, all money and non-callable Government
Securities (including the proceeds thereof) deposited with the Trustee (or other
qualifying trustee, collectively for purposes of this Section 8.05, the
"Trustee") pursuant to Section 8.04 hereof in respect of the outstanding Senior
Subordinated Notes shall be held in trust and applied by the Trustee, in
accordance with the provisions of such Senior Subordinated Notes and this
Indenture, to the payment, either directly or through any Paying Agent
(including the Authority acting as Paying Agent) as the Trustee may determine,
to the Holders of such Senior Subordinated Notes of all sums due and to become
due thereon in respect of principal, premium, if any, and interest, but such
money need not be segregated from other funds except to the extent required by
law.

     The Authority shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the cash or non-callable Government
Securities deposited pursuant to Section 8.04 hereof or the principal and
interest received in respect thereof other than any such tax, fee or other
charge which by law is for the account of the Holders of the outstanding Senior
Subordinated Notes.

     Anything in this Article 8 to the contrary notwithstanding, the Trustee
shall deliver or pay to the Authority from time to time upon the request of the
Authority any money or non-callable Government Securities held by it as provided
in Section 8.04 hereof which, in the opinion of a nationally recognized firm of
independent public accountants expressed in a written certification thereof
delivered to the Trustee (which may be the opinion delivered under Section
8.04(a) hereof), are in excess of the amount

<PAGE>
 
thereof that would then be required to be deposited to effect an equivalent
Legal Defeasance or Covenant Defeasance.

Section 8.06.  Repayment to Authority.

     Any money deposited with the Trustee or any Paying Agent, or then held by
the Authority, in trust for the payment of the principal of, premium, if any, or
interest on any Senior Subordinated Note and remaining unclaimed for two years
after such principal, and premium, if any, or interest has become due and
payable shall be paid to the Authority on its request or (if then held by the
Authority) shall be discharged from such trust; and the Holder of such Senior
Subordinated Note shall thereafter look only to the Authority for payment
thereof, and all liability of the Trustee or such Paying Agent with respect to
such trust money, and all liability of the Authority as trustee thereof, shall
thereupon cease; provided, however, that the Trustee or such Paying Agent,
before being required to make any such repayment, may at the expense of the
Authority cause to be published once, in the New York Times and The Wall Street
Journal (national edition), notice that such money remains unclaimed and that,
after a date specified therein, which shall not be less than 30 days from the
date of such notification or publication, any unclaimed balance of such money
then remaining will be repaid to the Authority.

Section 8.07.  Reinstatement.

     If the Trustee or Paying Agent is unable to apply any United States dollars
or non-callable Government Securities in accordance with Section 8.02 or 8.03
hereof, as the case may be, by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such
application, then the Authority's obligations under this Indenture and the
Senior Subordinated Notes shall be revived and reinstated as though no deposit
had occurred pursuant to Section 8.02 or 8.03 hereof until such time as the
Trustee or Paying Agent is permitted to apply all such money in accordance with
Section 8.02 or 8.03 hereof, as the case may be; provided, however, that, if the
Authority makes any payment of principal of, premium, if any, or interest on any
Senior Subordinated Note following the reinstatement of its obligations, the
Authority shall be subrogated to the rights of the Holders of such Senior
Subordinated Notes to receive such payment from the money held by the Trustee or
Paying Agent.

                        AMENDMENT, SUPPLEMENT AND WAIVER

Section 9.01.  Without Consent of Holders of Senior Subordinated Notes.

     Notwithstanding Section 9.02 of this Indenture, provided that any required
governmental approval to ensure the enforceability of the Senior Subordinated
Notes and this Indenture, including that of the BIA is obtained, the Authority,
the Subsidiary Guarantors, if any, and the Trustee may amend or supplement this
Indenture, the Senior Subordinated Subsidiary Guarantees, if any, or the Senior
Subordinated Notes without the consent of any Holder of a Senior Subordinated
Note to:

     (a) cure any ambiguity, defect or inconsistency;

     (b) provide for uncertificated Senior Subordinated Notes in addition to or
in place of certificated Senior Subordinated Notes or to alter the provisions of
Article 2 hereof (including the related definitions) in a manner that does not
materially adversely affect any Holder;

<PAGE>
 
     (c) provide for the assumption of the Authority's or a Subsidiary
Guarantor's obligations to the Holders of the Senior Subordinated Notes by a
successor to the Authority or such Subsidiary Guarantor;

     (d) make any change that would provide any additional rights or benefits to
the Holders of the Senior Subordinated Notes or that does not adversely affect
the legal rights hereunder of any Holder of the Senior Subordinated Notes;

     (e) comply with requirements of the SEC in order to effect or maintain the
qualification of this Indenture under the TIA; or

     (f) allow any Subsidiary to execute a supplemental indenture and/or a
Senior Subordinated Subsidiary Guarantee with respect to the Senior Subordinated
Notes.

     Upon the request of the Authority accompanied by a resolution of its
Management Board authorizing the execution of any such amended or supplemental
Indenture, and upon receipt by the Trustee of the documents described in Section
7.02 hereof, the Trustee shall join with the Authority and the Subsidiary
Guarantors, if any, in the execution of any amended or supplemental Indenture
authorized or permitted by the terms of this Indenture and to make any further
appropriate agreements and stipulations that may be therein contained, but the
Trustee shall not be obligated to enter into such amended or supplemental
Indenture that affects its own rights, duties or immunities under this Indenture
or otherwise.

Section 9.02.  With Consent of Holders of Senior Subordinated Notes.

     (a) Except as provided below in this Section 9.02, the Authority and the
Trustee may amend or supplement this Indenture (including Sections 3.10 and 4.10
hereof), the Senior Subordinated Subsidiary Guarantees, if any, and the Senior
Subordinated Notes may be amended or supplemented:

          (i) with the consent of the Holders of at least a majority in
     principal amount of the Senior Subordinated Notes then outstanding voting
     as a single class (including consents obtained in connection with a tender
     offer or exchange offer for, or purchase of, the Senior Subordinated
     Notes), and, subject to Sections 6.04 and 6.07 hereof, any existing Default
     or Event of Default (other than a Default or Event of Default in the
     payment of the principal of, premium, if any, or interest on the Senior
     Subordinated Notes, except a payment default resulting from an acceleration
     that has been rescinded) or compliance with any provision of this
     Indenture, the Senior Subordinated Subsidiary Guarantees or the Senior
     Subordinated Notes may be waived with the consent of the Holders of a
     majority in principal amount of the then outstanding Senior Subordinated
     Notes voting as a single class (including consents obtained in connection
     with a tender offer or exchange offer for, or purchase of, the Senior
     Subordinated Notes);

          (ii) without the consent of at least 66 2/3% of the aggregate
     principal amount of Senior Subordinated Notes then outstanding (including
     consents obtained in connection with a tender offer or exchange offer for,
     or purchase of, such Senior Subordinated Notes), no waiver or amendment to
     this Indenture may make a change in the provisions of Section 4.15 hereof
     that adversely affects the rights of any Holder of Senior Subordinated
     Notes and

          (iii) without the consent of at least 75% of the aggregate principal
     amount of Senior Subordinated Notes then outstanding (including consents
     obtained in connection with a tender offer or exchange offer for, or
     purchase of, such Senior Subordinated Notes), no waiver or amendment to
     this Indenture may make a change in the provisions of Article 10 hereof
     that adversely affects the rights of any Holder of Senior Subordinated
     Notes.

<PAGE>
 
     (b) Section 2.08 hereof shall determine which Senior Subordinated Notes are
considered to be "outstanding" for purposes of this Section 9.02.

     (c) Upon the request of the Authority accompanied by a resolution of its
Management Board authorizing the execution of any such amended or supplemental
Indenture, and upon the filing with the Trustee of evidence satisfactory to the
Trustee of the consent of the Holders of Senior Subordinated Notes as aforesaid,
and upon receipt by the Trustee of the documents described in Section 7.02
hereof, the Trustee shall join with the Authority in the execution of such
amended or supplemental Indenture unless such amended or supplemental Indenture
directly affects the Trustee's own rights, duties or immunities under this
Indenture or otherwise, in which case the Trustee may in its discretion, but
shall not be obligated to, enter into such amended or supplemental Indenture.

     (d) It shall not be necessary for the consent of the Holders of Senior
Subordinated Notes under this Section 9.02 to approve the particular form of any
proposed amendment or waiver, but it shall be sufficient if such consent
approves the substance thereof.

     (e) After an amendment, supplement or waiver under this Section becomes
effective, the Authority shall mail to the Holders of Senior Subordinated Notes
affected thereby a notice briefly describing the amendment, supplement or
waiver. Any failure of the Authority to mail such notice, or any defect therein,
shall not, however, in any way impair or affect the validity of any such amended
or supplemental Indenture or waiver. Subject to Sections 6.04 and 6.07 hereof,
the Holders of a majority in aggregate principal amount of the Senior
Subordinated Notes then outstanding voting as a single class may waive
compliance in a particular instance by the Authority with any provision of this
Indenture or the Senior Subordinated Notes. However, without the consent of each
Holder affected, an amendment or waiver under this Section 9.02 may not (with
respect to any Senior Subordinated Notes held by a non-consenting Holder):

          (i) reduce the principal amount of Senior Subordinated Notes whose
     Holders must consent to an amendment, supplement or waiver;

          (ii) reduce the principal of or change the fixed maturity of any
     Senior Subordinated Note or alter or waive any of the provisions with
     respect to the redemption of the Senior Subordinated Notes except as
     provided above with respect to Sections 3.10, 4.10 and 4.15 hereof;

          (iii) reduce the rate of or change the time for payment of interest,
     including default interest, on any Senior Subordinated Note;

          (iv) waive a Default or Event of Default in the payment of principal
     of or premium, if any, or interest on the Senior Subordinated Notes (except
     a rescission of acceleration of the Senior Subordinated Notes by the
     Holders of at least a majority in aggregate principal amount of the then
     outstanding Senior Subordinated Notes and a waiver of the payment default
     that resulted from such acceleration);

          (v) make any Senior Subordinated Note payable in money other than that
     stated in the Senior Subordinated Notes;

          (vi) make any change in the provisions of this Indenture relating to
     waivers of past Defaults or the rights of Holders of Senior Subordinated
     Notes to receive payments of principal of or interest on the Senior
     Subordinated Notes;

          (vii) waive a redemption payment with respect to any Note (other than
     a payment required by 3.10, 4.10 and 4.15 hereof);

          (viii) make any change in Section 6.04 or 6.07 hereof or in the
     foregoing amendment and waiver provisions; or

          (ix) release any Subsidiary Guarantor from any of its obligations
     under its Senior Subordinated Subsidiary Guarantee or this Indenture,
     except in accordance with the terms of its Senior Subordinated Subsidiary
     Guarantee.

Section 9.03.  Compliance with Trust Indenture Act.

     Every amendment or supplement to this Indenture or the Senior Subordinated
Notes shall be set forth in a amended or supplemental Indenture that complies
with the TIA as then in effect.

Section 9.04.  Revocation and Effect of Consents.

     Until an amendment, supplement or waiver becomes effective, a consent to it
by a Holder of a Senior Subordinated Note is a continuing consent by the Holder
of a Senior Subordinated Note and every subsequent Holder of a Senior
Subordinated Note or portion of a Senior Subordinated Note that evidences the
same debt as the consenting Holder's Senior Subordinated Note, even if notation
of the consent is not made on any Senior Subordinated Note. However, any such
Holder of a Senior Subordinated Note or subsequent Holder of a Senior
Subordinated Note may revoke the consent as to its Senior Subordinated Note if
the Trustee receives written notice of revocation before the date the waiver,
supplement or amendment becomes effective. An amendment, supplement or waiver
becomes effective in accordance with its terms and thereafter binds every
Holder.

Section 9.05.  Notation on or Exchange of Senior Subordinated Notes.

     The Trustee may place an appropriate notation about an amendment,
supplement or waiver on any Senior Subordinated Note thereafter authenticated.
The Authority in exchange for all Senior Subordinated Notes may issue and the
Trustee shall, upon receipt of an Authentication Order, authenticate new Senior
Subordinated Notes that reflect the amendment, supplement or waiver.

     Failure to make the appropriate notation or issue a new Senior Subordinated
Note shall not affect the validity and effect of such amendment, supplement or
waiver.

Section 9.06.  Trustee to Sign Amendments, etc.

     The Trustee shall sign any amended or supplemental Indenture authorized
pursuant to this Article Nine if the amendment or supplement does not adversely
affect the rights, duties, liabilities or immunities of the Trustee. The
Authority may not sign an amendment or supplemental Indenture until the
Management Board approves it. In executing any amended or supplemental
indenture, the Trustee shall be entitled to receive and (subject to Section 7.01
hereof) shall be fully protected in relying upon, in addition to the documents
required by Section 12.04 hereof, an Officer's Certificate and an Opinion of
Counsel stating that the execution of such amended or supplemental indenture is
authorized or permitted by this Indenture.

                                   ARTICLE 10
                                  SUBORDINATION

Section 10.01. Agreement to Subordinate.

     The Authority agrees, and each Holder by accepting a Senior Subordinated
Note agrees, that the Indebtedness evidenced by the Senior Subordinated Notes is
subordinated in right of payment, to the


                                       73
                                                       Senior Subordinated Notes
<PAGE>
 
extent and in the manner provided in this Article 10, to the prior payment in
full of all Senior Indebtedness (whether outstanding on the date hereof or
hereafter created, incurred, assumed or guaranteed), and that the subordination
is for the benefit of the holders of Senior Indebtedness. The provisions of this
Article 10 are made for the benefit of the holders of any Senior Indebtedness,
each of which is made an obligee hereunder and any one or more of which may
enforce such provisions. The provisions of this Article 10 shall be reinstated
if at any time any payment made on account of any Senior Indebtedness is
rescinded or must otherwise be returned by the holder receiving payment thereof
or any representative of such holder upon the insolvency, bankruptcy or
reorganization of the Authority or otherwise.

Section 10.02. Certain Definitions.

     "Permitted Junior Securities" means Equity Interests in the Authority or
any Senior Subordinated Guarantor or debt securities that are subordinated to
all Senior Indebtedness (and any debt securities issued in exchange for Senior
Indebtedness) to substantially the same extent as, or to a greater extent than,
the Senior Subordinated Notes are subordinated to Senior Indebtedness pursuant
to this Indenture.

     "Representative" means the indenture trustee or other trustee, agent or
representative for any Senior Indebtedness.

Section 10.03. Liquidation; Dissolution; Bankruptcy.

     Upon any distribution to creditors in a liquidation or dissolution of the
Authority or the Tribe, in a bankruptcy, reorganization, insolvency,
receivership or similar proceeding relating to the Authority, the Tribe or their
respective property, in an assignment for the benefit of creditors or in any
marshaling of the Authority's or the Tribe's assets and liabilities:

          (i) holders of Senior Indebtedness shall be entitled to receive
     payment in full of all Obligations due in respect of such Senior
     Indebtedness (including interest after the commencement of any such
     proceeding at the rate specified in the applicable Senior Indebtedness)
     before Holders of the Senior Subordinated Notes shall be entitled to
     receive any payment with respect to the Senior Subordinated Notes (except
     that Holders of Senior Subordinated Notes may receive and retain (A)
     Permitted Junior Securities and (B) payments and other distributions made
     from any defeasance trust created pursuant to Section 8.01 hereof); and

          (ii) until all Obligations with respect to Senior Indebtedness (as
     provided in clause (i) above) are paid in full, any distribution to which
     Holders would be entitled but for this Article 10 shall be made to holders
     of Senior Indebtedness (except that Holders of Senior Subordinated Notes
     may receive and retain (A) Permitted Junior Securities and (B) payments and
     other distributions made from any defeasance trust created pursuant to
     Section 8.01 hereof), as their interests may appear.

Section 10.04. Default on Designated Senior Indebtedness.

     (a) The Authority may not make any payment or distribution to the Trustee
or any Holder in respect of Obligations with respect to the Senior Subordinated
Notes and may not acquire from the Trustee or any Holder any Senior Subordinated
Notes for cash or property (other than (A) Permitted Junior Securities and (B)
payments and other distributions made from any defeasance trust created pursuant
to Section 8.01 hereof) until all principal and other Obligations with respect
to the Senior Indebtedness have been paid in full if:


                                       74
                                                       Senior Subordinated Notes
<PAGE>
 
          (i) a default in the payment of any principal or other Obligations
     with respect to Designated Senior Indebtedness occurs and is continuing
     beyond any applicable grace period in the agreement, indenture or other
     document governing such Designated Senior Indebtedness; or

          (ii) a default, other than a payment default, on Designated Senior
     Indebtedness occurs and is continuing that then permits holders of the
     Designated Senior Indebtedness to accelerate its maturity and the Trustee
     receives a notice of the default (a "Payment Blockage Notice") from a
     Person who may give it pursuant to Section 10.12 hereof. If the Trustee
     receives any such Payment Blockage Notice, no subsequent Payment Blockage
     Notice shall be effective for purposes of this Section unless and until (A)
     at least 360 days shall have elapsed since the effectiveness of the
     immediately prior Payment Blockage Notice and (B) all scheduled payments of
     principal, premium, if any, and interest on the Senior Subordinated Notes
     that have come due have been paid in full in cash. No nonpayment default
     that existed or was continuing on the date of delivery of any Payment
     Blockage Notice to the Trustee shall be, or be made, the basis for a
     subsequent Payment Blockage Notice unless such default shall have been
     waived for a period of not less than 180 days.

     (b) The Authority may and shall resume payments on and distributions in
respect of the Senior Subordinated Notes and may acquire them upon the earlier
of:

          (i) the date upon which all Senior Indebtedness is paid in full and in
     cash or the default is cured or waived in writing, or

          (ii) in the case of a default referred to in clause (ii) of Section
     10.04(a) hereof, 179 days pass after notice is received if the maturity of
     such Designated Senior Indebtedness has not been accelerated,

if this Article 10 otherwise permits the payment, distribution or acquisition at
the time of such payment or acquisition.

Section 10.05. Acceleration of Senior Subordinated Notes.

     If payment of the Senior Subordinated Notes is accelerated because of an
Event of Default, the Authority shall promptly notify holders of Senior
Indebtedness of the acceleration.

Section 10.06. When Distribution Must Be Paid Over.

     In the event that the Trustee or any Holder receives any payment of any
Obligations with respect to the Senior Subordinated Notes at a time when a
Responsible Officer of the Trustee or such Holder, as applicable, has actual
knowledge that such payment is prohibited by Section 10.04 hereof, such payment
shall be held by the Trustee or such Holder, in trust for the benefit of, and
shall be paid forthwith over and delivered, upon written request, to, the
holders of Senior Indebtedness as their interests may appear or their
Representative under the indenture or other agreement (if any) pursuant to which
Senior Indebtedness may have been issued, as their respective interests may
appear, for application to the payment of all Obligations with respect to Senior
Indebtedness remaining unpaid to the extent necessary to pay such Obligations in
full and in cash in accordance with their terms, after giving effect to any
concurrent payment or distribution to or for the holders of Senior Indebtedness.

     With respect to the holders of Senior Indebtedness, the Trustee undertakes
to perform only such obligations on the part of the Trustee as are specifically
set forth in this Article 10, and no implied covenants or obligations with
respect to the holders of Senior Indebtedness shall be read into this Indenture
against the Trustee. The Trustee shall not be deemed to owe any fiduciary duty
to the holders


                                       75
                                                       Senior Subordinated Notes
<PAGE>
 
of Senior Indebtedness, and shall not be liable to any such holders if the
Trustee shall pay over or distribute to or on behalf of Holders or the Authority
or any other Person money or assets to which any holders of Senior Indebtedness
shall be entitled by virtue of this Article 10, except if such payment is made
as a result of the willful misconduct or gross negligence of the Trustee.

Section 10.07. Notice by Authority.

     The Authority shall promptly notify the Trustee and the Paying Agent of any
facts known to the Authority that would cause a payment of any Obligations with
respect to the Senior Subordinated Notes to violate this Article 10, but failure
to give such notice shall not affect the subordination of the Senior
Subordinated Notes to Senior Indebtedness as provided in this Article 10.

Section 10.08. Subrogation.

     After all Senior Indebtedness is paid in full and until the Senior
Subordinated Notes are paid in full, Holders of Senior Subordinated Notes shall
be subrogated (equally and ratably with all other Indebtedness pari passu with
the Senior Subordinated Notes) to the rights of holders of Senior Indebtedness
to receive distributions applicable to Senior Indebtedness to the extent that
distributions otherwise payable to the Holders of Senior Subordinated Notes have
been applied to the payment of Senior Indebtedness. A distribution made under
this Article 10 to holders of Senior Indebtedness that otherwise would have been
made to Holders of Senior Subordinated Notes is not, as between the Authority
and Holders, a payment by the Authority on the Senior Subordinated Notes.

Section 10.09. Relative Rights.

     This Article 10 defines the relative rights of Holders of Senior
Subordinated Notes and holders of Senior Indebtedness. Nothing in this Indenture
shall:

          (i) impair, as between the Authority and Holders of Senior
     Subordinated Notes, the obligation of the Authority, which is absolute and
     unconditional, to pay principal of and interest on the Senior Subordinated
     Notes in accordance with their terms;

          (ii) affect the relative rights of Holders of Senior Subordinated
     Notes and creditors of the Authority other than their rights in relation to
     holders of Senior Indebtedness; or

          (iii) prevent the Trustee or any Holder of Senior Subordinated Notes
     from exercising its available remedies upon a Default or Event of Default,
     subject to the rights of holders and owners of Senior Indebtedness to
     receive distributions and payments otherwise payable to Holders of Senior
     Subordinated Notes.

     If the Authority fails because of this Article 10 to pay principal of or
interest on a Senior Subordinated Note on the due date, the failure is still a
Default or Event of Default.

Section 10.10. Subordination May Not Be Impaired.

     No right of any holder of Senior Indebtedness to enforce the subordination
of the Indebtedness evidenced by the Senior Subordinated Notes shall be impaired
by any act or failure to act by the Authority or any Holder or by the failure of
the Authority or any Holder to comply with this Indenture. No right of any
present or future holder of any Senior Indebtedness to enforce the subordination
provided in this Article 10 shall at any time or in any way be prejudiced or
impaired by any act or failure to act by such holder, or any non-compliance by
the Tribe, the Authority or any Subsidiary Guarantor with the terms of this
Indenture, regardless of any knowledge thereof which any such holder may have or


                                       76
                                                       Senior Subordinated Notes
<PAGE>
 
otherwise be charged with. The holders of Senior Indebtedness may, without
notice to or consent of any Holders, (i) extend, renew, modify or amend the
terms of the Senior Indebtedness (including changing the terms of payment) or
any security therefor and release, sell or exchange such security or release any
person in any manner liable for such Senior Indebtedness, (ii) exercise or
refrain from exercising any rights against the Tribe, the Authority, any
Subsidiary Guarantor or any other person (including the holders), and (iii)
apply any sums by whomsoever paid, or howsoever realized to any Senior
Indebtedness in such manner as the holder of the Senior Indebtedness may
determine.

Section 10.11. Distribution or Notice to Representative.

     Whenever a distribution is to be made or a notice given to holders of
Senior Indebtedness, the distribution may be made and the notice given to their
Representative.

     Upon any payment or distribution of assets of the Authority referred to in
this Article 10, the Trustee and the Holders of Senior Subordinated Notes shall
be entitled to rely upon any order or decree made by any court of competent
jurisdiction or upon any certificate of such Representative or of the
liquidating trustee or agent or other Person making any distribution to the
Trustee or to the Holders of Senior Subordinated Notes for the purpose of
ascertaining the Persons entitled to participate in such distribution, the
holders of the Senior Indebtedness and other Indebtedness of the Authority, the
amount thereof or payable thereon, the amount or amounts paid or distributed
thereon and all other facts pertinent thereto or to this Article 10.

Section 10.12. Rights of Trustee and Paying Agent.

     Notwithstanding the provisions of this Article 10 or any other provision of
this Indenture, the Trustee shall not be charged with knowledge of the existence
of any facts that would prohibit the making of any payment or distribution by
the Trustee, and the Trustee and the Paying Agent may continue to make payments
on the Senior Subordinated Notes, unless the Trustee shall have received at its
Corporate Trust Office at least five Business Days prior to the date of such
payment written notice of facts that would cause the payment of any Obligations
with respect to the Senior Subordinated Notes to violate this Article 10. Only
the Authority or a Representative may give the notice. Nothing in this Article
10 shall impair the claims of, or payments to, the Trustee under or pursuant to
Section 7.07 hereof.

     The Trustee in its individual or any other capacity may hold Senior
Indebtedness with the same rights it would have if it were not Trustee. Any
Agent may do the same with like rights.

Section 10.13. Authorization to Effect Subordination.

     Each Holder of Senior Subordinated Notes, by the Holder's acceptance
thereof, authorizes and directs the Trustee on such Holder's behalf to take such
action as may be necessary or appropriate to effectuate the subordination as
provided in this Article 10, and appoints the Trustee to act as such Holder's
attorney-in-fact for any and all such purposes. If the Trustee does not file a
proper proof of claim or proof of debt in the form required in any proceeding
referred to in Section 6.09 hereof at least 30 days before the expiration of the
time to file such claim, the Representatives are hereby authorized to file an
appropriate claim for and on behalf of the Holders of the Senior Subordinated
Notes. No holder of any Senior Indebtedness and no Representative of such holder
shall have (i) any duty to file any such proof of claim or proof of debt or (ii)
any liability to any Holder if any such proof of claim or proof of debt is for
any reason defective.

Section 10.14. Amendments.

     The provisions of this Article 10 shall not be amended or modified without
the written consent of the holders of all Senior Indebtedness.

                                   ARTICLE 11
                             COVENANTS OF THE TRIBE

          Authority or on any patrons of, or any activity at, the Resort other
          than:

          (i)   payments which are due under any agreement in effect on the
                Closing Date or payments which are not materially adverse to the
                economic interests of Holders;

          (ii)  payments which the Authority has agreed to reimburse each Holder
                for the economic effect thereof, if any;

          (iii) payments which correspondingly reduce the Restricted Payments
                otherwise payable to the Tribe;

          (iv)  pursuant to the Tribal Tax Code; or

          (v)   Government Service Payments;

          materially adverse to the economic interests of Holders;

     (c)  amend the Tribal Gaming Ordinance in effect on the Closing Date

          Authority and the Resort conduct gaming operations in a manner that is
          consistent with applicable laws, rules and regulations or that
          protects the environment, the public health and safety, or the
          integrity of the Authority or the Resort), restrict or eliminate the
          exclusive right of the Authority to conduct gaming operations on any
          property owned or controlled by the Tribe in a manner that would be
          materially adverse to the economic interests of Holders; or

     (d)  take any other action, enter into any agreement, amend its
          constitution or enact any ordinance, law, rule or regulation that
          would have a material adverse effect on the economic interests of
          Holders.

     Moreover, except with the consent of a majority in interest of Holders or
as required by federal or state law, the Tribe shall not, and shall not permit
any of its representatives, political subunits or councils, agencies,
instrumentalities, to, directly or indirectly impose, tax or otherwise make a
charge on the Senior Subordinated Notes, this Indenture or any payments or
deposits to be made thereunder.

Section 11.02. Additional Covenants of the Tribe.

     (a) Any action taken by the Tribe to comply with federal or state law that
would otherwise violate Section 11.01 shall be taken only after prior written
notice to the Trustee, accompanied with an Officers' Certificate and Opinion of
Counsel that such action is required by federal or state law. To the extent
possible under the federal or state law, the Tribe shall give the Trustee at
least 30 days prior written notice of any such action.

     (b) The Tribe will not permit or incur any consensual liability of the
Tribe (or of any other instrumentality or subunit of the Tribe) that is a legal
obligation of the Authority, or for which the Authority's assets may be bound,
other than a liability that the Authority is permitted or not prohibited from
incurring on its own behalf under this Indenture.

     (c) In the event that the Tribe receives any payment from the Authority at
a time when such payment is prohibited by the terms of this Indenture, such
payment shall be held by the Tribe in trust for the benefit of, and shall be
paid forthwith over and delivered, upon the written request of the Trustee or
the Authority, to the Authority.

     (d) The Tribe will not, pursuant to or within the meaning of Bankruptcy
Law, appoint or consent to the appointment of a Custodian of the Authority or
for all or substantially all of the property of the Authority.

     (e) The Tribe agrees that it will not enact any Bankruptcy Law or similar
law for the relief of debtors that would impair, limit, restrict, delay or
otherwise adversely affect any of the rights and remedies of the Trustee or the
Holders provided for in this Indenture or the Senior Subordinated Notes.

     (f) The Tribe agrees that it will not, and will not permit the Authority or
any of the Tribe's representatives, political subunits, agencies,
instrumentalities or councils to, exercise any power of eminent domain over the
property that is the subject of the Lease (other than any such exercise that
would not materially adversely affect the economic rights and benefits of the
Trustee or the Holders thereunder). Except as required by federal or state law,
the Tribe will not enact any statute, law, ordinance or rule that would have a
material adverse affect on the rights of the Trustee or the Holders under this
Indenture or the Senior Subordinated Notes.

     (g) The Tribe hereby agrees that upon any payment or distribution of assets
upon any liquidation, dissolution, winding up, reorganization, assignment for
the benefit of creditors, marshalling of assets or any bankruptcy, insolvency or
similar proceedings of the Authority or the Resort, the Holders of the Senior
Subordinated Notes shall be entitled to receive payment in full in respect to
all principal, premium, interest and other amounts owing in respect of the Notes

     Capitalized terms used herein shall have the meanings assigned to them in
the Indenture referred to below unless otherwise indicated.

     1.   INTEREST.

     (a) The Mohegan Tribal Gaming Authority (the "Authority"), promises to pay
interest on the principal amount of this Senior Subordinated Note at 83/4% per
annum from March 3, 1999 until maturity.


                                     A-1-2
<PAGE>
 
The Authority will pay interest and Additional Interest, if any, semi-annually
in arrears on January 1 and July 1 of each year, or if any such day is not a
Business Day, on the next succeeding Business Day (each an "Interest Payment
Date"). Interest on the Senior Subordinated Notes will accrue from the most
recent date to which interest has been paid or, if no interest has been paid,
from the date of original issuance; provided that if there is no existing
Default in the payment of interest, and if this Senior Subordinated Note is
authenticated between a record date referred to on the face hereof and the next
succeeding Interest Payment Date, interest shall accrue from such next
succeeding Interest Payment Date; provided, further, that the first Interest
Payment Date shall be July 1, 1999. The Authority shall pay interest (including
post-petition interest in any proceeding under any Bankruptcy Law) on overdue
principal and premium, if any, from time to time on demand at a rate that is 1%
per annum in excess of the rate then in effect; it shall pay interest (including
post-petition interest in any proceeding under any Bankruptcy Law) on overdue
installments of interest and Additional Interest, if any, (without regard to any
applicable grace periods) from time to time on demand at the same rate to the
extent lawful. Interest will be computed on the basis of a 360-day year of
twelve 30-day months.

     (b) The Holder of this Senior Subordinated Note is entitled to the benefits
of the Senior Subordinated Registration Rights Agreement dated as of the date
hereof, among the Authority and the Initial Purchasers named therein ( the
"Senior Subordinated Registration Rights Agreement"). If (i) the Authority fails
to file any of the Registration Statements required by the Registration Rights
Agreements on or before the date specified for such filing, (ii) any of such
Registration Statements is not declared effective by the Commission on or prior
to the date specified for such effectiveness (the "Effectiveness Target Date"),
(iii) the Authority fails to consummate the Exchange Offer within 30 business
days of the Effectiveness Target Date with respect to the Exchange Offer
Registration Statement, or (iv) the Shelf Registration Statement or the Exchange
Offer Registration Statement is declared effective but thereafter ceases to be
effective or usable in connection with resales of Transfer Restricted Securities
during the periods specified in the Registration Rights Agreement (each such
event referred to in clauses (i) through (iv) above a "Registration Default"),
then the Authority will pay Additional Interest to each Holder of Senior
Subordinated Notes, with respect to the first 90-day period immediately
following the occurrence of the first Registration Default in an amount equal to
25 basis points per 90-day period of the principal amount of Senior Subordinated
Notes held by such Holder. The amount of the Additional Interest will increase
by an additional 25 basis points with respect to each subsequent 90-day period
until all Registration Defaults have been cured, up to a maximum amount of
Additional Interest of 1% per annum of the principal amount of Senior
Subordinated Notes.

          (A) Except as expressly provided in this paragraph 1(b), Additional
     Interest shall be treated as interest and any date on which Additional
     Interest is due and payable shall be treated as an Interest Payment Date
     for all purposes under this Senior Subordinated Note and the Indenture.

          (B) In the event that the Authority is required to pay Additional
     Interest pursuant to this paragraph 1(b), the Authority shall notify the
     Trustee in writing at least 15 days prior to the first Interest Payment
     Date upon which such Additional Interest is due; provided that, in the
     event that the obligation to pay such Additional Interest occurs less than
     15 days prior to such Additional Interest Date, such notice shall be
     provided by the Authority to the Trustee as soon as reasonably practicable
     prior to such Interest Payment Date.

     2. METHOD OF PAYMENT. The Authority will pay interest on the Senior
Subordinated Notes (except defaulted interest) and Additional Interest, if any,
to the Persons who are registered Holders of Senior Subordinated Notes at the
close of business on the December 15 or June 15 next preceding the Interest
Payment Date, even if such Senior Subordinated Notes are canceled after such
record date and on or before such Interest Payment Date, except as provided in
Section 2.12 of the Indenture with respect to defaulted interest. The Senior
Subordinated Notes will be payable as to principal, premium and


                                     A-1-3
<PAGE>
 
Additional Interest, if any, and interest at the office or agency of the
Authority maintained for such purpose within or without the City and State of
New York, or, at the option of the Authority, payment of interest and Additional
Interest may be made by check mailed to the Holders at their addresses set forth
in the register of Holders, and provided that payment by wire transfer of
immediately available funds will be required with respect to principal of and
interest, premium and Additional Interest on, all Global Senior Subordinated
Notes and all other Senior Subordinated Notes the Holders of which shall hold at
least $1.0 million in principal amount of Senior Subordinated Notes and have
provided wire transfer instructions to the Authority or the Paying Agent. Such
payment shall be in such coin or currency of the United States of America as at
the time of payment is legal tender for payment of public and private debts.

     3. PAYING AGENT AND REGISTRAR. Initially, State Street Bank and Trust
Company, the Trustee under the Indenture, will act as Paying Agent and
Registrar. The Authority may change any Paying Agent or Registrar without notice
to any Holder. The Authority or any of its Subsidiaries may act in any such
capacity.

     4. INDENTURE. The Authority issued the Senior Subordinated Notes under an
Indenture dated as of March 3, 1999 ("Indenture") between the Authority and the
Trustee. The terms of the Senior Subordinated Notes include those stated in the
Indenture and those made part of the Indenture by reference to the Trust
Indenture Act of 1939, as amended (15 U.S. Code ss.ss. 77aaa-77bbbb). The Senior
Subordinated Notes are subject to all such terms, and Holders are referred to
the Indenture and such Act for a statement of such terms. To the extent any
provision of this Senior Subordinated Note conflicts with the express provisions
of the Indenture, the provisions of the indenture shall govern and be
controlling.

     5. OPTIONAL REDEMPTION.

     (a) Except as set forth in subparagraph (b) of this Paragraph 5, the
Authority shall not have the option to redeem the Senior Subordinated Notes
prior to January 1, 2004. Thereafter, the Authority shall have the option to
redeem the Senior Subordinated Notes, in whole or in part, upon not less than 30
nor more than 60 days' notice, at the redemption prices (expressed as

</TABLE>

     (b) Notwithstanding any other provisions of Article 3 of the Indenture, if
any Gaming Regulatory Authority requires that a Holder or beneficial owner of
the Notes be licensed, qualified or found suitable under any applicable gaming
laws in order to maintain any gaming license or franchise of the Authority under
any applicable gaming laws, and the Holder or beneficial owner fails to apply
for a license, qualification or finding of suitability within 30 days after
being requested to do so by such Gaming Regulatory Authority (or such lesser
period that may be required by such Gaming Regulatory Authority) or if such
Holder or beneficial owner is not so licensed, qualified or found suitable, the
Authority has the right, at its option, (i) to require such Holder or beneficial
owner to dispose of such Holder's or beneficial owner's Senior Subordinated
Notes within 30 days of receipt of such notice of such finding by the applicable
Gaming Regulatory Authority (or such earlier date as may be required by the
applicable Gaming Regulatory Authority); or (ii) to call for redemption of the
Senior Subordinated Notes of such Holder or beneficial owner at a redemption
price equal to the lesser of (1) the principal amount


                                     A-1-4
<PAGE>
 
thereof or (2) the price at which such Holder or beneficial owner acquired the
Senior Subordinated Notes or (3) the current market price of the Senior
Subordinated Notes, together with, in either case, accrued and unpaid interest
and Additional Interest, if any, to the earlier of the date of redemption or the
date of the finding of unsuitability by such Gaming Regulatory Authority, which
may be less than 30 days following the notice of redemption if so ordered by
such Gaming Regulatory Authority. The Authority shall not be required to pay or
reimburse any Holder or beneficial owner of Senior Subordinated Notes who is
required to apply for any such license, qualification or finding of suitability
for the costs of the licensure or investigation for such qualification or
finding of suitability. Such expenses shall be the obligation of such Holder or
beneficial owner.

     6. MANDATORY REDEMPTION.

     Except as set forth in paragraph 7 below, the Authority shall not be
required to make mandatory redemption payments with respect to the Senior
Subordinated Notes.

     7. REPURCHASE AT OPTION OF HOLDER.

     (a) If there is a Change of Control, the Authority shall be required to
make an offer (a "Change of Control Offer") to repurchase all or any part (equal
to $1,000 or an integral multiple thereof) of each Holder's Senior Subordinated
Notes at a purchase price equal to 101% of the aggregate principal amount
thereof plus accrued and unpaid interest and Additional Interest thereon, if
any, to the date of purchase (the "Change of Control Payment"). Within 20
Business Days following any Change of Control, the Authority shall mail a notice
to each Holder setting forth the procedures governing the Change of Control
Offer as required by the Indenture.

     (b) If the Authority or a Subsidiary consummates any Asset Sales, within
five Business Days of each date on which the aggregate amount of Excess Proceeds
exceeds $15.0 million, the Authority shall commence an offer to all Holders of
Senior Subordinated Notes (as "Asset Sale Offer") pursuant to Section 3.10 of
the Indenture to purchase the maximum principal amount of Senior Subordinated
Notes that may be purchased out of the Excess Proceeds at an offer price in cash
in an amount equal to 100% of the principal amount thereof plus accrued and
unpaid interest and Additional Interest thereon, if any, to the date fixed for
the closing of such offer, in accordance with the procedures set forth in the
Indenture. To the extent that the aggregate amount of Senior Subordinated Notes
tendered pursuant to an Asset Sale Offer is less than the Excess Proceeds, the
Authority (or such Subsidiary) may use such deficiency for any purpose not
otherwise permitted by the Indenture. If the aggregate principal amount of
Senior Subordinated Notes surrendered by Holders thereof exceeds the amount of
Excess Proceeds, the Trustee shall select the Senior Subordinated Notes to be
purchased on a pro rata basis. Holders of Senior Subordinated Notes that are the
subject of an offer to purchase will receive an Asset Sale Offer from the
Authority prior to any related purchase date and may elect to have such Senior
Subordinated Notes purchased by completing the form entitled "Option of Holder
to Elect Purchase" on the reverse of the Senior Subordinated Notes.

     8. NOTICE OF REDEMPTION. Notice of redemption will be mailed at least 30
days but not more than 60 days before the redemption date to each Holder whose
Senior Subordinated Notes are to be redeemed at its registered address. Senior
Subordinated Notes in denominations larger than $1,000 may be redeemed in part
but only in whole multiples of $1,000, unless all of the Senior Subordinated
Notes held by a Holder are to be redeemed. On and after the redemption date
interest ceases to accrue on Senior Subordinated Notes or portions thereof
called for redemption.

     9. DENOMINATIONS, TRANSFER, EXCHANGE. The Senior Subordinated Notes are in
registered form without coupons in denominations of $1,000 and integral
multiples of $1,000. The transfer of

Senior Subordinated Notes may be registered and Senior Subordinated Notes may be
exchanged as provided in the Indenture. The Registrar and the Trustee may
require a Holder, among other things, to furnish appropriate endorsements and
transfer documents and the Authority may require a Holder to pay any taxes and
fees required by law or permitted by the Indenture. The Authority need not
exchange or register the transfer of any Senior Subordinated Note or portion of
a Senior Subordinated Note selected for redemption, except for the unredeemed
portion of any Senior Subordinated Note being redeemed in part. Also, the
Authority need not exchange or register the transfer of any Senior Subordinated
Notes for a period of 15 days before a selection of Senior Subordinated Notes to
be redeemed or during the period between a record date and the corresponding
Interest Payment Date.

     10. PERSONS DEEMED OWNERS. The registered Holder of a Senior Subordinated
Note may be treated as its owner for all purposes.

     11. AMENDMENT, SUPPLEMENT AND WAIVER. Subject to certain exceptions, the
Indenture, the Senior Subordinated Subsidiary Guarantees or the Senior
Subordinated Notes may be amended or supplemented with the consent of the
Holders of at least a majority in principal amount of the then outstanding
Senior Subordinated Notes, voting as a single class, and any existing default or
compliance with any provision of the Indenture, the Senior Subordinated
Subsidiary Guarantees or the Senior Subordinated Notes may be waived with the
consent of the Holders of a majority in principal amount of the then outstanding

Holder of a Senior Subordinated Note, the Indenture, the Senior Subordinated
Subsidiary Guarantees or the Senior Subordinated Notes may be amended or
supplemented to cure any ambiguity, defect or inconsistency, to provide for
uncertificated Senior Subordinated Notes in addition to or in place of
certificated Senior Subordinated Notes, to provide for the assumption of the
Authority's or Subsidiary Guarantor's obligations to Holders of the Senior
Subordinated Notes by a successor to the Authority or such Subsidiary Guarantor,
to make any change that would provide any additional rights or benefits to the
Holders of the Senior Subordinated Notes or that does not adversely affect the
legal rights under the Indenture of any such Holder, to comply with the
requirements of the SEC in order to effect or maintain the qualification of the
Indenture under the Trust Indenture Act or to allow any Subsidiary Guarantor to
execute a supplemental indenture to the Indenture and/or a Senior Subordinated
Subsidiary Guarantee with respect to the Senior Subordinated Notes provided that
the Authority has obtained any required government approval to ensure the
enforceability of the Senior Subordinated Notes and the Indenture.

days in the payment when due of interest or Additional Interest on the Senior

maturity; (vi) certain final judgments for the payment of money that remain
undischarged for a period of 60 days; (vii) certain events of bankruptcy or
insolvency with respect to the Authority or any of its Restricted Subsidiaries;

of more than 90 consecutive days at the Resort (other than as a result of a
casualty loss); (x) the Lease ceases to be in full force and effect; (xi) except
as permitted by the Indenture, any Senior Subordinated Subsidiary Guarantee
shall be held in any judicial proceeding to be unenforceable or invalid or shall

or any Person acting on its behalf shall deny or disaffirm its obligations under
such Subsidiary Guarantor's Senior Subordinated Subsidiary Guarantee; and (xii)
failure by the Tribe to comply with the provisions of Article 11 for 30 days
after notice to the Authority and the Tribe by the Trustee or the Holders of at
least 25% in aggregate principal amount of the Senior Subordinated Notes then

continuing, the Trustee or the Holders of at least 25% in principal amount of
the then outstanding Senior Subordinated Notes may declare all the Senior
Subordinated Notes to be due and payable. Notwithstanding the foregoing, in the
case of an Event of Default arising from certain events of bankruptcy or
insolvency, all outstanding Senior Subordinated Notes will become due and
payable without further action or notice. Holders may not enforce the Indenture
or the Senior Subordinated Notes except as provided in the Indenture. Subject to
certain limitations, Holders of a majority in principal amount of the then
outstanding Senior Subordinated Notes may direct the Trustee in its exercise of
any trust or power. The Trustee may withhold from Holders of the Senior
Subordinated Notes notice of any continuing Default or Event of Default (except
a Default or Event of Default relating to the payment of principal or interest)
if it determines that withholding notice is in their interest. The Holders of a
majority in aggregate principal amount of the Senior Subordinated Notes then
outstanding by notice to the Trustee may on behalf of the Holders of all of the
Senior Subordinated Notes waive any existing Default or Event of Default and its
consequences under the Indenture except a continuing Default or Event of Default
in the payment of interest on, or the principal of, the Senior Subordinated
Notes. The Authority is required to deliver to the Trustee annually a statement
regarding compliance with the Indenture, and the Authority is required upon
becoming aware of any Default or Event of Default, to deliver to the Trustee a
statement specifying such Default or Event of Default.

     13. TRUSTEE DEALINGS WITH AUTHORITY. The Trustee, in its individual or any
other capacity, may make loans to, accept deposits from, and perform services
for the Authority or its Affiliates, and may otherwise deal with the Authority
or its Affiliates, as if it were not the Trustee.

     14. NO RECOURSE AGAINST OTHERS. A controlling person, director, officer,
employee or holder of an Ownership Interest of the Authority, as such, shall not
have any liability for any obligations of the Authority under the Senior
Subordinated Notes or the Indenture or for any claim based on, in respect of, or
by reason of, such obligations or their creation. Each Holder by accepting a
Senior Subordinated Note waives and releases all such liability. The waiver and
release are part of the consideration for the issuance of the Senior
Subordinated Notes.

     15. AUTHENTICATION. This Senior Subordinated Note shall not be valid until
authenticated by the manual signature of the Trustee or an authenticating agent.

     16. ABBREVIATIONS. Customary abbreviations may be used in the name of a
Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (=
tenants by the entireties), JT TEN (= joint tenants with right of survivorship
and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts
to Minors Act).

     17. ADDITIONAL RIGHTS OF HOLDERS OF RESTRICTED GLOBAL SENIOR SUBORDINATED
NOTES AND RESTRICTED DEFINITIVE SENIOR SUBORDINATED NOTES. In addition to the
rights provided to Holders of Senior Subordinated Notes under the Indenture,
Holders of Restricted Global Senior Subordinated Notes and Restricted Definitive
Senior Subordinated Notes shall have all the rights set forth in the Senior

Subordinated Registration Rights Agreement dated as of March 3, 1999, between
the Authority and the parties named on the signature pages thereof (the "Senior
Subordinated Registration Rights Agreement").

     18. CUSIP NUMBERS. Pursuant to a recommendation promulgated by the
Committee on Uniform Security Identification Procedures, the Authority has
caused CUSIP numbers to be printed on the Senior Subordinated Notes and the
Trustee may use CUSIP numbers in notices of redemption as a convenience to
Holders. No representation is made as to the accuracy of such numbers either as
printed on the Senior Subordinated Notes or as contained in any notice of
redemption and reliance may be placed only on the other identification numbers
placed thereon.

charge a copy of the Indenture and/or the Senior Subordinated Registration
Rights Agreement. Requests may be made to:

     Capitalized terms used herein shall have the meanings assigned to them in
the Indenture referred to below unless otherwise indicated.

     1. INTEREST.

     (a) The Mohegan Tribal Gaming Authority (the "Authority"), promises to pay
interest on the principal amount of this Senior Subordinated Note at 83/4% per
annum from March 3, 1999 until maturity. The Authority will pay interest and
Additional Interest, if any, semi-annually in arrears on January 1 and July 1 of
each year, or if any such day is not a Business Day, on the next succeeding
Business Day (each an "Interest Payment Date"). Interest on the Senior
Subordinated Notes will accrue from the most recent date to which interest has
been paid or, if no interest has been paid, from the date of original issuance;
provided that if there is no existing Default in the payment of interest, and if
this Senior Subordinated Note is authenticated between a record date referred to
on the face hereof and the next succeeding Interest Payment Date, interest shall
accrue from such next succeeding Interest Payment Date; provided, further, that
the first Interest Payment Date shall be July 1, 1999. The Authority shall pay
interest (including post-petition interest in any proceeding under any
Bankruptcy Law) on overdue principal and premium, if any, from time to time on
demand at a rate that is 1% per annum in excess of the rate then in effect; it
shall pay interest (including post-petition interest in any proceeding under any
Bankruptcy Law) on overdue installments of interest and Additional Interest, if
any, (without regard to any applicable grace periods) from time to time on
demand at the same rate to the extent lawful. Interest will be computed on the
basis of a 360-day year of twelve 30-day months.

     (b) The Holder of this Senior Subordinated Note is entitled to the benefits
of the Senior Subordinated Registration Rights Agreement dated as of the date
hereof, among the Authority and the Initial Purchasers named therein ( the
"Senior Subordinated Registration Rights Agreement"). If (i) the Authority fails
to file any of the Registration Statements required by the Registration Rights
Agreements on or before the date specified for such filing, (ii) any of such
Registration Statements is not declared effective by the Commission on or prior
to the date specified for such effectiveness (the "Effectiveness Target Date"),
(iii) the Authority fails to consummate the Exchange Offer within 30 business
days of the Effectiveness Target Date with respect to the Exchange Offer
Registration Statement, or (iv) the Shelf Registration Statement or the Exchange
Offer Registration Statement is declared effective but thereafter ceases to be
effective or usable in connection with resales of Transfer Restricted Securities
during the periods specified in the Registration Rights Agreement (each such
event referred to in clauses (i) through (iv) above a "Registration Default"),
then the Authority will pay Additional Interest to each Holder of Senior
Subordinated Notes, with respect to the first 90-day period immediately
following the occurrence of the first Registration Default in an amount equal to
25 basis points per 90-day period of the principal amount of Senior Subordinated
Notes held by such Holder. The amount of the Additional Interest will increase
by an additional 25 basis points with respect to each subsequent 90-day period
until all Registration Defaults have been cured, up to a maximum amount of
Additional Interest of 1% per annum of the principal amount of Senior
Subordinated Notes.

     (A) Except as expressly provided in this paragraph 1(b), Additional
Interest shall be treated as interest and any date on which Additional Interest
is due and payable shall be treated as an Interest Payment Date for all purposes
under this Senior Subordinated Note and the Indenture.

                                     A-2-3
<PAGE>
 
     (B) In the event that the Authority is required to pay Additional Interest
pursuant to this paragraph 1(b), the Authority shall notify the Trustee in
writing at least 15 days prior to the first Interest Payment Date upon which
such Additional Interest is due; provided that, in the event that the obligation
to pay such Additional Interest occurs less than 15 days prior to such
Additional Interest Date, such notice shall be provided by the Authority to the
Trustee as soon as reasonably practicable prior to such Interest Payment Date.

     2. METHOD OF PAYMENT. The Authority will pay interest on the Senior
Subordinated Notes (except defaulted interest) and Additional Interest, if any,
to the Persons who are registered Holders of Senior Subordinated Notes at the
close of business on the December 15 or June 15 next preceding the Interest
Payment Date, even if such Senior Subordinated Notes are canceled after such
record date and on or before such Interest Payment Date, except as provided in
Section 2.12 of the Indenture with respect to defaulted interest. The Senior
Subordinated Notes will be payable as to principal, premium and Additional
Interest, if any, and interest at the office or agency of the Authority
maintained for such purpose within or without the City and State of New York,
or, at the option of the Authority, payment of interest and Additional Interest,
if any, may be made by check mailed to the Holders at their addresses set forth
in the register of Holders, and provided that payment by wire transfer of
immediately available funds will be required with respect to principal of and
interest, premium and Additional Interest on, all Global Senior Subordinated
Notes and all other Senior Subordinated Notes the Holders of which shall hold at
least $1.0 million in principal amount of Senior Subordinated Notes and have
provided wire transfer instructions to the Authority or the Paying Agent. Such
payment shall be in such coin or currency of the United States of America as at
the time of payment is legal tender for payment of public and private debts.

     3. PAYING AGENT AND REGISTRAR. Initially, State Street Bank and Trust
Company, the Trustee under the Indenture, will act as Paying Agent and
Registrar. The Authority may change any Paying Agent or Registrar without notice
to any Holder. The Authority or any of its Subsidiaries may act in any such
capacity.

     4. INDENTURE. The Authority issued the Senior Subordinated Notes under an
Indenture dated as of March 3, 1999 ("Indenture") between the Authority and the
Trustee. The terms of the Senior Subordinated Notes include those stated in the
Indenture and those made part of the Indenture by reference to the Trust
Indenture Act of 1939, as amended (15 U.S. Code ss.ss. 77aaa-77bbbb). The Senior
Subordinated Notes are subject to all such terms, and Holders are referred to
the Indenture and such Act for a statement of such terms. To the extent any
provision of this Senior Subordinated Note conflicts with the express provisions
of the Indenture, the provisions of the indenture shall govern and be
controlling.

     5. OPTIONAL REDEMPTION.

     (a) Except as set forth in subparagraph (b) of this Paragraph 5, the
Authority shall not have the option to redeem the Senior Subordinated Notes
prior to January 1, 2004. Thereafter, the Authority shall have the option to
redeem the Senior Subordinated Notes, in whole or in part, upon not less than 30
nor more than 60 days' notice, at the redemption prices (expressed as
percentages of principal amount) set forth below plus accrued and unpaid
interest and Additional Interest thereon to the applicable redemption date, if

     (b) Notwithstanding any other provisions of Article 3 of the Indenture, if
any Gaming Regulatory Authority requires that a Holder or beneficial owner of
the Notes be licensed, qualified or found suitable under any applicable gaming
laws in order to maintain any gaming license or franchise of the Authority under
any applicable gaming laws, and the Holder or beneficial owner fails to apply
for a license, qualification or finding of suitability within 30 days after
being requested to do so by such Gaming Regulatory Authority (or such lesser
period that may be required by such Gaming Regulatory Authority) or if such
Holder or beneficial owner is not so licensed, qualified or found suitable, the
Authority has the right, at its option, (i) to require such Holder or beneficial
owner to dispose of such Holder's or beneficial owner's Senior Subordinated
Notes within 30 days of receipt of such notice of such finding by the applicable
Gaming Regulatory Authority (or such earlier date as may be required by the
applicable Gaming Regulatory Authority); or (ii) to call for redemption of the
Senior Subordinated Notes of such Holder or beneficial owner at a redemption
price equal to the lesser of (1) the principal amount thereof or (2) the price
at which such Holder or beneficial owner acquired the Senior Subordinated Notes
or (3) the current market price of the Senior Subordinated Notes, together with,
in either case, accrued and unpaid interest and Additional Interest, if any, to
the earlier of the date of redemption or the date of the finding of
unsuitability by such Gaming Regulatory Authority, which may be less than 30
days following the notice of redemption if so ordered by such Gaming Regulatory
Authority. The Authority shall not be required to pay or reimburse any Holder or
beneficial owner of Senior Subordinated Notes who is required to apply for any
such license, qualification or finding of suitability for the costs of the
licensure or investigation for such qualification or finding of suitability.
Such expenses shall be the obligation of such Holder or beneficial owner.

     6. MANDATORY REDEMPTION.

     Except as set forth in paragraph 7 below, the Authority shall not be
required to make mandatory redemption payments with respect to the Senior
Subordinated Notes.

     7. REPURCHASE AT OPTION OF HOLDER.

     (a) If there is a Change of Control, the Authority shall be required to
make an offer (a "Change of Control Offer") to repurchase all or any part (equal
to $1,000 or an integral multiple thereof) of each Holder's Senior Subordinated
Notes at a purchase price equal to 101% of the aggregate principal amount
thereof plus accrued and unpaid interest and Additional Interest thereon, if
any, to the date of purchase (the "Change of Control Payment"). Within 20
Business Days following any Change of Control, the Authority shall mail a notice
to each Holder setting forth the procedures governing the Change of Control
Offer as required by the Indenture.

     (b) If the Authority or a Subsidiary consummates any Asset Sales, within
five Business Days of each date on which the aggregate amount of Excess Proceeds
exceeds $15.0 million, the Authority shall commence an offer to all Holders of
Senior Subordinated Notes (as "Asset Sale Offer") pursuant to Section 3.10 of
the Indenture to purchase the maximum principal amount of Senior Subordinated
Notes that may be purchased out of the Excess Proceeds at an offer price in cash
in an amount equal to 100% of the principal amount thereof plus accrued and
unpaid interest and Additional Interest thereon, if any, to the date fixed for
the closing of such offer, in accordance with the procedures set forth in the
Indenture. To the extent that the aggregate amount of Senior Subordinated Notes
tendered pursuant to an Asset Sale 


                                     A-2-5
<PAGE>
 
Offer is less than the Excess Proceeds, the Authority (or such Subsidiary) may
use such deficiency for any purpose not otherwise permitted by the Indenture. If
the aggregate principal amount of Senior Subordinated Notes surrendered by
Holders thereof exceeds the amount of Excess Proceeds, the Trustee shall select
the Senior Subordinated Notes to be purchased on a pro rata basis. Holders of
Senior Subordinated Notes that are the subject of an offer to purchase will
receive an Asset Sale Offer from the Authority prior to any related purchase
date and may elect to have such Senior Subordinated Notes purchased by
completing the form entitled "Option of Holder to Elect Purchase" on the reverse
of the Senior Subordinated Notes.

     8. NOTICE OF REDEMPTION. Notice of redemption will be mailed at least 30
days but not more than 60 days before the redemption date to each Holder whose
Senior Subordinated Notes are to be redeemed at its registered address. Senior
Subordinated Notes in denominations larger than $1,000 may be redeemed in part
but only in whole multiples of $1,000, unless all of the Senior Subordinated
Notes held by a Holder are to be redeemed. On and after the redemption date
interest ceases to accrue on Senior Subordinated Notes or portions thereof
called for redemption.

     9. DENOMINATIONS, TRANSFER, EXCHANGE. The Senior Subordinated Notes are in
registered form without coupons in denominations of $1,000 and integral
multiples of $1,000. The transfer of Senior Subordinated Notes may be registered
and Senior Subordinated Notes may be exchanged as provided in the Indenture. The
Registrar and the Trustee may require a Holder, among other things, to furnish
appropriate endorsements and transfer documents and the Authority may require a
Holder to pay any taxes and fees required by law or permitted by the Indenture.
The Authority need not exchange or register the transfer of any Senior
Subordinated Note or portion of a Senior Subordinated Note selected for
redemption, except for the unredeemed portion of any Senior Subordinated Note
being redeemed in part. Also, the Authority need not exchange or register the
transfer of any Senior Subordinated Notes for a period of 15 days before a
selection of Senior Subordinated Notes to be redeemed or during the period
between a record date and the corresponding Interest Payment Date.

     This Regulation S Temporary Global Note is exchangeable in whole or in part
for one or more Global Notes only (i) on or after the termination of the 40-day
restricted period (as defined in Regulation S) and (ii) upon presentation of
certificates (accompanied by an Opinion of Counsel, if applicable) required by
Article 2 of the Indenture. Upon exchange of this Regulation S Temporary Global
Note for one or more Global Notes, the Trustee shall cancel this Regulation S
Temporary Note.

     10. PERSONS DEEMED OWNERS. The registered Holder of a Senior Subordinated
Note may be treated as its owner for all purposes.

     11. AMENDMENT, SUPPLEMENT AND WAIVER. Subject to certain exceptions, the
Indenture, the Senior Subordinated Subsidiary Guarantees or the Senior
Subordinated Notes may be amended or supplemented with the consent of the
Holders of at least a majority in principal amount of the then outstanding
Senior Subordinated Notes, voting as a single class, and any existing default or
compliance with any provision of the Indenture, the Senior Subordinated
Subsidiary Guarantees or the Senior Subordinated Notes may be waived with the
consent of the Holders of a majority in principal amount of the then outstanding

Holder of a Senior Subordinated Note, the Indenture, the Senior Subordinated
Subsidiary Guarantees or the Senior Subordinated Notes may be amended or
supplemented to cure any ambiguity, defect or inconsistency, to provide for
uncertificated Senior Subordinated Notes in addition to or in place of
certificated Senior Subordinated Notes, to provide for the assumption of the
Authority's or Subsidiary Guarantor's obligations to Holders of the Senior
Subordinated Notes by a successor to the Authority or such Subsidiary Guarantor,
to make any change that would provide any additional rights or benefits to the
Holders of the Senior Subordinated Notes or that does not adversely affect the
legal rights under the


                                     A-2-6
<PAGE>
 
Indenture of any such Holder, to comply with the requirements of the SEC in
order to effect or maintain the qualification of the Indenture under the Trust
Indenture Act or to allow any Subsidiary Guarantor to execute a supplemental
indenture to the Indenture and/or a Senior Subordinated Subsidiary Guarantee
with respect to the Senior Subordinated Notes provided that the Authority has
obtained any required government approval to ensure the enforceability of the
Senior Subordinated Notes and the Indenture.

     12. DEFAULTS AND REMEDIES. Events of Default include: (i) default for 30
days in the payment when due of interest or Additional Interest on the Senior
Subordinated Notes; (ii) default in payment when due of principal of or premium,
if any, on the Senior Subordinated Notes when the same becomes due and payable

Subsidiaries to comply with Section 4.10 or 5.01 of the Indenture; (iv) failure

aggregate principal amount of the Senior Subordinated Notes then outstanding
voting as a single class or (B) any other covenant, representation, warranty or
other agreement in the Indenture or the Senior Subordinated Notes for 60 days
after notice to the Authority by the Trustee or the Holders of at least 25% in
aggregate principal amount of the Senior Subordinated Notes then outstanding
voting as a single class; (v) default under certain other agreements relating to
Indebtedness of the Authority or any of its Restricted Subsidiaries which
default results in the acceleration of such Indebtedness prior to its express
maturity; (vi) certain final judgments for the payment of money that remain
undischarged for a period of 60 days; (vii) certain events of bankruptcy or
insolvency with respect to the Authority or any of its Restricted Subsidiaries;
(viii) revocation, termination, suspension or other cessation of effectiveness
of any Gaming License which results in the cessation or suspension of gaming

cessation of gaming operations for a period of more than 90 consecutive days at
the Resort (other than as a result of a casualty loss); (x) the Lease ceases to
be in full force and effect; (xi) except as permitted by the Indenture, any
Senior Subordinated Subsidiary Guarantee shall be held in any judicial
proceeding to be unenforceable or invalid or shall cease for any reason to be in
full force and effect or any Subsidiary Guarantor or any Person acting on its
behalf shall deny or disaffirm its obligations under such Subsidiary Guarantor's
Senior Subordinated Subsidiary Guarantee; and (xii) failure by the Tribe to
comply with the provisions in Article 11 for 30 days after notice to the
Authority and the Tribe by the Trustee or the Holders of at least 25% in
aggregate principal amount of the Senior Subordinated Notes then outstanding
voting as a single class. If any Event of Default occurs and is continuing, the
Trustee or the Holders of at least 25% in principal amount of the then
outstanding Senior Subordinated Notes may declare all the Senior Subordinated
Notes to be due and payable. Notwithstanding the foregoing, in the case of an
Event of Default arising from certain events of bankruptcy or insolvency, all
outstanding Senior Subordinated Notes will become due and payable without
further action or notice. Holders may not enforce the Indenture or the Senior
Subordinated Notes except as provided in the Indenture. Subject to certain
limitations, Holders of a majority in principal amount of the then outstanding
Senior Subordinated Notes may direct the Trustee in its exercise of any trust or
power. The Trustee may withhold from Holders of the Senior Subordinated Notes
notice of any continuing Default or Event of Default (except a Default or Event
of Default relating to the payment of principal or interest) if it determines
that withholding notice is in their interest. The Holders of a majority in
aggregate principal amount of the Senior Subordinated Notes then outstanding by
notice to the Trustee may on behalf of the Holders of all of the Senior
Subordinated Notes waive any existing Default or Event of Default and its
consequences under the Indenture except a continuing Default or Event of Default
in the payment of interest on, or the principal of, the Senior Subordinated
Notes. The Authority is required to deliver to the Trustee annually a statement
regarding compliance with the Indenture, and the Authority is required upon
becoming aware of any Default or Event of Default, to deliver to the Trustee a
statement specifying such Default or Event of Default.

     13. TRUSTEE DEALINGS WITH AUTHORITY. The Trustee, in its individual or any
other capacity, may make loans to, accept deposits from, and perform services
for the Authority or its Affiliates, and may otherwise deal with the Authority
or its Affiliates, as if it were not the Trustee.

     14. NO RECOURSE AGAINST OTHERS. A controlling person, director, officer,
employee or holder of an Ownership Interest of the Authority, as such, shall not
have any liability for any obligations of the Authority under the Senior
Subordinated Notes or the Indenture or for any claim based on, in respect of, or
by reason of, such obligations or their creation. Each Holder by accepting a
Senior Subordinated Note waives and releases all such liability. The waiver and
release are part of the consideration for the issuance of the Senior
Subordinated Notes.

     15. AUTHENTICATION. This Senior Subordinated Note shall not be valid until
authenticated by the manual signature of the Trustee or an authenticating agent.

Trustee may use CUSIP numbers in notices of redemption as a convenience to
Holders. No representation is made as to the accuracy of such numbers either as
printed on the Senior Subordinated Notes or as contained in any notice of
redemption and reliance may be placed only on the other identification numbers
placed thereon.

specified in Annex A hereto, in the principal amount of $___________ in such
Senior Subordinated Note[s] or interests (the "Transfer"), to

     Securities Act of 1933, as amended (the "Securities Act"), and,
     accordingly, the Transferor hereby further certifies that the beneficial

     is a "qualified institutional buyer" within the meaning of Rule 144A in a
     transaction meeting the requirements of Rule 144A and such Transfer is in
     compliance with any applicable blue sky securities laws of any state of the
     United States. Upon consummation of the proposed Transfer in accordance
     with the terms of the Indenture, the transferred beneficial interest or

     Subordinated Note pursuant to Regulation S. The Transfer is being effected

     behalf reasonably believed and believes that the Transferee was outside the
     United States or (y) the transaction was executed in, on or through the
     facilities of a designated offshore securities market and neither such
     Transferor nor any Person acting on its behalf


                                      B-1
<PAGE>
 
     knows that the transaction was prearranged with a buyer in the United
     States, (ii) no directed selling efforts have been made in contravention of
     the requirements of Rule 903(b) or Rule 904(b) of Regulation S under the
     Securities Act; (iii) the transaction is not part of a plan or scheme to
     evade the registration requirements of the Securities Act and (iv) if the
     proposed transfer is being made prior to the expiration of the Distribution
     Compliance Period, the transfer is not being made to a U.S. Person or for
     the account or benefit of a U.S. Person (other than an Initial Purchaser).)
     Upon consummation of the proposed transfer in accordance with the terms of
     the Indenture, the transferred beneficial interest or Definitive Senior
     Subordinated Note will be subject to the restrictions on Transfer
     enumerated in the Private Placement Legend printed on the Regulation S
     Global Senior Subordinated Note, the Temporary Regulation S Global Senior
     Subordinated Note and/or the Definitive Senior Subordinated Note and in the
     Indenture and the Securities Act.

          3. [_] Check and complete if Transferee will take delivery of a
     beneficial interest in the Definitive Senior Subordinated Note pursuant to
     any provision of the Securities Act other than Rule 144A or Regulation S.

     applicable to beneficial interests in Restricted Global Senior Subordinated
     Notes and Restricted Definitive Senior Subordinated Notes and pursuant to

               (c) [_] such Transfer is being effected pursuant to an effective
          registration statement under the Securities Act and in compliance with
          the prospectus delivery requirements of the Securities Act;

an officer of such Subsidiary Guarantor on each Senior Note authenticated and
delivered by the Trustee after the date hereof.

     (b) Notwithstanding the foregoing, the Subsidiary Guarantor hereby agrees
that its Senior Subsidiary Guarantee set forth herein shall remain in full force
and effect notwithstanding any failure to endorse on each Senior Note a notation
of such Senior Subordinated Subsidiary Guarantee.

     (c) If an officer whose signature is on this Supplemental Indenture or on
the Senior Subordinated Subsidiary Guarantee no longer holds that office at the
time the Trustee authenticates the Senior Subordinated Note on which a Senior
Subordinated Subsidiary Guarantee is endorsed, the Senior Subsidiary Guarantee
shall be valid nevertheless.

     (d) The delivery of the Senior Subordinated Note by the Trustee, after the
authentication thereof under the Indenture, shall constitute due delivery of the
Senior Subordinated Subsidiary Guarantee set forth in this Supplemental
Indenture on behalf of the Subsidiary Guarantor.

     (e) The Subsidiary Guarantor hereby agrees that its obligations hereunder
shall be unconditional, regardless of the validity, regularity or enforceability
of the Senior Subordinated Notes or the Indenture, the absence of any action to
enforce the same, any waiver or consent by any Holder of the Senior Subordinated
Notes with respect to any provisions hereof or thereof, the recovery of any
judgment against the Authority, any action to enforce the same or any other

of payment, filing of claims with a court in the event of insolvency or
bankruptcy of the Authority, any right to require a proceeding first against the

pursuant to Section 5(b) of this Supplemental Indenture.

     (g) If the Trustee or any Holder has instituted any proceeding to enforce
any right or remedy under this Supplemental Indenture and such proceeding has
been discontinued or abandoned for any reason, or has been determined adversely
to the Trustee or to such Holder, then, and in every such case, subject to any
determination in such proceeding, the Subsidiary Guarantor, the Trustee and the
Holders shall be restored severally and respectively to their former positions
hereunder and thereafter

                                      E-2
<PAGE>
 
all rights and remedies of the Subsidiary Guarantor, the Trustee and the Holders
shall continue as though no such proceeding had been instituted.

     (h) The Subsidiary Guarantor hereby waives and will not in any manner
whatsoever claim or take the benefit or advantage of, any rights of
reimbursement, indemnity or subrogation or any other rights against the
Authority or any other Subsidiary Guarantor as a result of any payment by such
Subsidiary Guarantor under its Senior Subordinated Subsidiary Guarantee. The
Subsidiary Guarantor further agrees that, as between the Subsidiary Guarantors,
on the one hand, and the Holders and the Trustee, on the other hand:

          (i) the maturity of the obligations guaranteed hereby may be
     accelerated as provided in Article 6 of the Indenture for the purposes of
     the Senior Subordinated Subsidiary Guarantee made pursuant to this
     Supplemental Indenture, notwithstanding any stay, injunction or other
     prohibition preventing such acceleration in respect of the obligations
     guaranteed hereby; and

          (ii) in the event of any declaration of acceleration of such
     obligations as provided in Article 6, such obligations (whether or not due
     and payable) shall forthwith become due and payable by the Subsidiary
     Guarantor for the purpose of the Senior Subordinated Subsidiary Guarantee
     made pursuant to this Supplemental Indenture.

     (i) The Subsidiary Guarantor shall have the right to seek contribution from
any other non-paying Subsidiary Guarantor, if any, so long as the exercise of
such right does not impair the rights of the Holders under the Senior
Subordinated Subsidiary Guarantee made pursuant to this Supplemental Indenture.

     (j) The Subsidiary Guarantor covenants (to the extent that it may lawfully
do so) that it will not at any time insist upon, or plead, or in any manner
whatsoever claim or take the benefit or advantage of, any stay, extension or
usury law wherever enacted, now or at any time hereafter in force, which may
affect the covenants or the performance of the Indenture or this Senior
Subordinated Subsidiary Guarantee; and the Subsidiary Guarantor (to the extent
that it may lawfully do so) hereby expressly waives all benefit or advantage of
any such law, and covenants that it will not hinder, delay or impede the
execution of any power herein granted to the Trustee, but will suffer and permit
the execution of every such power as though no such law had been enacted.

     5. SUBSIDIARY GUARANTOR MAY CONSOLIDATE, ETC. ON CERTAIN TERMS

     (a) Nothing contained in the Indenture, this Supplemental Indenture or in

     Tribe: The Mohegan Tribe of Indians of Connecticut, a sovereign tribe

SECTION 2. HOLDERS

     A person is deemed to be a holder of Transfer Restricted Securities (each,
a "Holder") whenever such person owns Transfer Restricted Securities.

SECTION 3. REGISTERED EXCHANGE OFFER

     (a) Unless the Exchange Offer shall not be permitted by applicable federal
law (after the procedures set forth in Section 6(a)(i) below have been complied
with), the Authority shall (i) cause the Exchange Offer Registration Statement
to be filed with the Commission as soon as practicable after the Closing Date,
but in no event later than 90 days after the Closing Date (such 90th day being
the "Filing Deadline"), (ii) use its best efforts to cause such Exchange Offer
Registration Statement to become effective at the earliest possible time, but in
no event later than 150 days after the Closing Date (such 150th day being the
"Effectiveness Deadline"), (iii) in connection with the foregoing, (A) file all
pre-effective amendments to such Exchange Offer Registration Statement as may be
necessary in order to cause it to become effective, (B) file, if applicable, a
post-effective amendment to such Exchange Offer Registration Statement pursuant
to Rule 430A under the Act and (C) cause all necessary filings, if any, in
connection with the registration and qualification of the Senior Subordinated
Exchange Notes to be made under the Blue Sky laws of such jurisdictions as are
necessary to permit Consummation of the Exchange Offer, and (iv) upon the
effectiveness of such Exchange Offer Registration Statement, commence and
Consummate the Exchange Offer. The Exchange Offer shall be on the appropriate
form permitting (i) registration of the Senior Subordinated Exchange Notes to be
offered in exchange for the Initial Senior Subordinated Notes that are Transfer
Restricted Securities and (ii) resales of Senior Subordinated Exchange Notes by
Broker-Dealers that tendered into the Exchange Offer Initial Senior Subordinated
Notes that such Broker-Dealer acquired for its own account as a result of market
making activities or other trading activities (other than Initial Senior
Subordinated Notes acquired directly from the Authority or any of its
Affiliates) as contemplated by Section 3(c) below.

     (b) The Authority shall use its best efforts to cause the Exchange Offer
Registration Statement to be effective continuously, and shall keep the Exchange
Offer open for a period of not less than the minimum period required under
applicable federal and state securities laws to Consummate the Exchange Offer;
provided, however, that in no event shall such period be less than 20 Business
Days. The Authority shall cause the Exchange Offer to comply with all applicable
federal and state securities laws. No securities other than the Senior
Subordinated Exchange Notes and the Senior Exchange Notes shall be included in
the Exchange Offer Registration Statement. The Authority shall use its best
efforts to cause the Exchange Offer to be Consummated on the earliest
practicable date after the Exchange Offer Registration Statement has become
effective, but in no event later than 30 Business Days thereafter (such 30th day
being the "Consummation Deadline").


                                       3
<PAGE>
 
     (c) The Authority shall include a "Plan of Distribution" section in the
Prospectus contained in the Exchange Offer Registration Statement and indicate
therein that any Broker-Dealer who holds Transfer Restricted Securities that
were acquired for the account of such Broker-Dealer as a result of market-making
activities or other trading activities (other than Initial Senior Subordinated
Notes acquired directly from the Authority or any Affiliate of the Authority),
may exchange such Transfer Restricted Securities pursuant to the Exchange Offer.
Such "Plan of Distribution" section shall also contain all other information
with respect to such sales by such Broker-Dealers that the Commission may
require in order to permit such sales pursuant thereto, but such "Plan of
Distribution" shall not name any such Broker-Dealer or disclose the amount of
Transfer Restricted Securities held by any such Broker-Dealer, except to the
extent required by the Commission as a result of a change in policy, rules or
regulations after the date of this Agreement.

     Because such Broker-Dealer may be deemed to be an "underwriter" within the
meaning of the Act and must, therefore, deliver a prospectus meeting the
requirements of the Act in connection with its initial sale of any Senior
Subordinated Exchange Notes received by such Broker-Dealer in the Exchange
Offer, the Authority shall permit the use of the Prospectus contained in the
Exchange Offer Registration Statement by such Broker-Dealer to satisfy such
prospectus delivery requirement. To the extent necessary to ensure that the
prospectus contained in the Exchange Offer Registration Statement is available
for sales of Senior Subordinated Exchange Notes by Broker-Dealers, the Authority
agrees to use its best efforts to keep the Exchange Offer Registration Statement
continuously effective, supplemented, amended and current as required by and
subject to the provisions of Section 6(a) and (c) hereof and in conformity with
the requirements of this Agreement, the Act and the policies, rules and
regulations of the Commission as announced from time to time, for a period of
one year from the Consummation Deadline or such shorter period as will terminate
when all Transfer Restricted Securities covered by such Registration Statement
have been sold pursuant thereto. The Authority shall provide sufficient copies
of the latest version of such Prospectus to such Broker-Dealers, promptly upon
request, and in no event later than one day after such request, at any time
during such period.

SECTION 4. SHELF REGISTRATION

     (a) Shelf Registration. If (i) the Exchange Offer is not permitted by
applicable law (after the Authority has complied with the procedures set forth
in Section 6(a)(i) below) or (ii) if any Holder of Transfer Restricted
Securities shall notify the Authority within 20 Business Days following the
Consummation Deadline that (A) such Holder was prohibited by law or Commission
policy from participating in the Exchange Offer or (B) such Holder may not
resell the Senior Subordinated Exchange Notes acquired by it in the Exchange
Offer to the public without delivering a prospectus and the Prospectus contained
in the Exchange Offer Registration Statement is not appropriate or available for
such resales by such Holder or (C) such Holder is a Broker-Dealer and holds
Initial Senior Subordinated Notes acquired directly from the Authority or any of
its Affiliates, then the Authority shall

     (x) cause to be filed, on or prior to 30 days after the earlier of (i) the
date on which the Authority determines that the Exchange Offer Registration
Statement cannot be filed as a result of clause (a)(i) above and (ii) the date
on which the Authority receives the notice specified in clause (a)(ii) above,
(such earlier date, the "Filing Deadline"), a shelf registration statement
pursuant to Rule 415 under the Act (which may be an amendment to the Exchange
Offer Registration Statement (the "Shelf Registration Statement")), relating to
all Transfer Restricted Securities, and

     (y) shall use its best efforts to cause such Shelf Registration Statement
to become effective on or prior to 90 days after the Filing Deadline for the
Shelf Registration Statement (such 90th day the "Effectiveness Deadline").

     If, after the Authority has filed an Exchange Offer Registration Statement
that satisfies the requirements of Section 3(a) above, the Authority is required
to file and make effective a Shelf Registration Statement solely because the
Exchange Offer is not permitted under applicable federal law (i.e. clause (a)(i)

above), then the filing of the Exchange Offer Registration Statement shall be
deemed to satisfy the requirements of clause (x) above; provided that, in such
event, the Authority shall remain obligated to meet the Effectiveness Deadline
set forth in clause (y).

     To the extent necessary to ensure that the Shelf Registration Statement is
available for sales of Transfer Restricted Securities by the Holders thereof
entitled to the benefit of this Section 4(a) and the other securities required
to be registered therein pursuant to Section 6(b)(ii) hereof, the Authority
shall use its best efforts to keep any Shelf Registration Statement required by
this Section 4(a) continuously effective, supplemented, amended and current as
required by and subject to the provisions of Sections 6(b) and (c) hereof and in
conformity with the requirements of this Agreement, the Act and the policies,
rules and regulations of the Commission as announced from time to time, for a
period of at least two years (as extended pursuant to Section 6(c)(i)) following
the Closing Date, or such shorter period as will terminate when all Transfer
Restricted Securities covered by such Shelf Registration Statement have been
sold pursuant thereto.

     (b) Provision by Holders of Certain Information in Connection with the
Shelf Registration Statement. No Holder of Transfer Restricted Securities may
include any of its Transfer Restricted Securities in any Shelf Registration
Statement pursuant to this Agreement unless and until such Holder furnishes to
the Authority in writing, within 20 days after receipt of a request therefor,
the information specified in Item 507 or 508 of Regulation S-K, as applicable,
of the Act for use in connection with any Shelf Registration Statement or
Prospectus or preliminary Prospectus included therein. No Holder of Transfer
Restricted Securities shall be entitled to additional interest pursuant to
Section 5 hereof unless and until such Holder shall have provided all such
information. Each selling Holder agrees to furnish promptly additional
information required to be disclosed in order to make the information previously
furnished to the Authority by such Holder not materially misleading.

SECTION 5. ADDITIONAL INTEREST

     If (i) any Registration Statement required by this Agreement is not filed
with the Commission on or prior to the applicable Filing Deadline, (ii) any such
Registration Statement has not been declared effective by the Commission on or
prior to the applicable Effectiveness Deadline, (iii) the Exchange Offer has not
been Consummated on or prior to the Consummation Deadline or (iv) any
Registration Statement required by this Agreement is filed and declared
effective but shall thereafter cease to be effective or fail to be usable for
its intended purpose without being succeeded within 2 days by a post-effective
amendment to such Registration Statement that cures such failure and that is
itself declared effective within 5 days of filing such post-effective amendment
to such Registration Statement (each such event referred to in clauses (i)
through (iv), a "Registration Default"), then the Authority hereby agrees to pay
to each Holder of Transfer Restricted Securities affected thereby additional
interest in an amount equal to 25 basis points per 90-day period of the
principal amount of Transfer Restricted Securities held by such Holder for the
90-day period or portion thereof that the Registration Default continues for the
first 90-day period immediately following the occurrence of such Registration
Default. The amount of the additional interest shall increase by an additional
25 basis points with respect to each subsequent 90-day period until all
Registration Defaults have been cured, up to a maximum amount of additional
interest of 1% per annum of the principal amount of Transfer Restricted
Securities; provided that the Authority shall in no event be required to pay
additional interest for more than one Registration Default at any given time.
Notwithstanding anything to the contrary set forth herein, (1) upon filing of
the Exchange Offer Registration Statement (and/or, if applicable, the Shelf
Registration Statement), in the case of (i) above, (2) upon the effectiveness of
the Exchange Offer Registration Statement (and/or, if applicable, the Shelf
Registration Statement), in the case of (ii) above, (3) upon Consummation of the
Exchange Offer, in the case of (iii) above, or (4) upon the filing of a
post-effective amendment to the Registration Statement or an additional
Registration Statement that causes the Exchange Offer Registration Statement
(and/or, if applicable, the Shelf Registration Statement) to again be declared
effective or made usable in the case of (iv) above, the additional interest
payable with respect to the Transfer Restricted Securities as a result of such
clause (i), (ii), (iii) or (iv), as applicable, shall cease.


                                       5
<PAGE>
 
     All accrued additional interest shall be paid to the Holders entitled
thereto, in the manner provided for the payment of interest in the Senior
Subordinated Notes Indenture and the Senior Subordinated Notes, on each Interest
Payment Date, as more fully set forth in the Senior Subordinated Notes Indenture
and the Senior Subordinated Notes. Notwithstanding the fact that any securities
for which additional interest is due cease to be Transfer Restricted Securities,
all obligations of the Authority to pay additional interest with respect to
securities shall survive until such time as such obligations with respect to
such securities shall have been satisfied in full.

SECTION 6. REGISTRATION PROCEDURES

     (a) Exchange Offer Registration Statement. In connection with the Exchange
Offer, the Authority shall (x) comply with all applicable provisions of Section
6(c) below, (y) use its best efforts to effect such exchange and to permit the
resale of Senior Subordinated Exchange Notes by Broker-Dealers that tendered in
the Exchange Offer Initial Senior Subordinated Notes that such Broker-Dealer
acquired for its own account as a result of its market making activities or
other trading activities (other than Initial Senior Subordinated Notes acquired
directly from the Authority or any of its Affiliates) being sold in accordance
with the intended method or methods of distribution thereof, and (z) comply with
all of the following provisions:

          (i) If, following the date hereof there has been announced a change in
     Commission policy with respect to exchange offers such as the Exchange
     Offer, that in the reasonable opinion of counsel to the Authority raises a
     substantial question as to whether the Exchange Offer is permitted by
     applicable federal law, the Authority hereby agrees to seek a no-action
     letter or other favorable decision from the Commission staff allowing the
     Authority to Consummate a Exchange Offer for such Transfer Restricted
     Securities. In connection with the foregoing, the Authority hereby agrees
     to take all actions as may be required in connection with the issuance of
     such decision, including without limitation (A) participating in telephonic
     conferences with the Commission, (B) delivering to the Commission staff an
     analysis prepared by counsel to the Authority setting forth the legal
     bases, if any, upon which such counsel has concluded that such an Exchange
     Offer should be permitted and (C) diligently pursuing a resolution (which
     need not be favorable) by the Commission staff.

          (ii) As a condition to its participation in the Exchange Offer, each
     Holder of Transfer Restricted Securities (including, without limitation,
     any Holder who is a Broker Dealer) shall furnish, upon the request of the
     Authority, prior to the Consummation of the Exchange Offer, a written
     representation to the Authority (which may be contained in the letter of
     transmittal contemplated by the Exchange Offer Registration Statement) to
     the effect that (A) it is not an Affiliate of the Authority, (B) it is not
     engaged in, and does not intend to engage in, and has no arrangement or
     understanding with any person to participate in, a distribution of the
     Senior Subordinated Exchange Notes to be issued in the Exchange Offer and
     (C) it is acquiring the Senior Subordinated Exchange Notes in its ordinary
     course of business. As a condition to its participation in the Exchange
     Offer, each Holder using the Exchange Offer to participate in a
     distribution of the Senior Subordinated Exchange Notes shall acknowledge
     and agree that, if the resales are of Senior Subordinated Exchange Notes
     obtained by such Holder in exchange for Initial Senior Subordinated Notes
     acquired directly from the Authority or an Affiliate thereof, it (1) could
     not, under Commission policy as in effect on the date of this Agreement,
     rely on the position of the Commission enunciated in Exxon Capital Holdings
     Corporation (available May 13, 1988) and Morgan Stanley and Co., Inc.
     (available June 5, 1991), as interpreted in the Commission's letter to
     Shearman & Sterling dated July 2, 1993, and similar no-action letters
     (including, if applicable, any no-action letter obtained pursuant to clause
     (i) above), and (2) must comply with the registration and prospectus
     delivery requirements of the Act in connection with a secondary resale
     transaction and that such a secondary resale transaction must be covered by
     an effective registration statement containing the selling security holder
     information required by Item 507 or 508, as applicable, of


                                       6
<PAGE>
 
     Regulation S-K.

          (iii) Prior to effectiveness of the Exchange Offer Registration
     Statement, the Authority shall provide a supplemental letter to the
     Commission (A) stating that the Authority is registering the Exchange Offer
     in reliance on the position of the Commission enunciated in Exxon Capital
     Holdings Corporation (available May 13, 1988) and Morgan Stanley and Co.,
     Inc. (available June 5, 1991) as interpreted in the Commission's letter to
     Shearman & Sterling dated July 2, 1993, and, if applicable, any no-action
     letter obtained pursuant to clause (i) above, (B) including a
     representation that the Authority has not entered into any arrangement or
     understanding with any person to distribute the Senior Subordinated
     Exchange Notes to be received in the Exchange Offer and that, to the best
     of the Authority's information and belief, each Holder participating in the
     Exchange Offer is acquiring the Senior Subordinated Exchange Notes in its
     ordinary course of business and has no arrangement or understanding with
     any person to participate in the distribution of the Senior Subordinated
     Exchange Notes received in the Exchange Offer and (C) any other undertaking
     or representation required by the Commission as set forth in any no-action
     letter obtained pursuant to clause (i) above, if applicable.

     (b) Shelf Registration Statement. In connection with the Shelf Registration
Statement, the Authority shall

          (i) comply with all the provisions of Section 6(c) below and use its
     best efforts to effect such registration to permit the sale of the Transfer
     Restricted Securities being sold in accordance with the intended method or
     methods of distribution thereof (as indicated in the information furnished
     to the Authority pursuant to Section 4(b) hereof), and pursuant thereto the
     Authority will prepare and file with the Commission a Registration
     Statement relating to the registration on any appropriate form under the
     Act, which form shall be available for the sale of the Transfer Restricted
     Securities in accordance with the intended method or methods of
     distribution thereof within the time periods and otherwise in accordance
     with the provisions hereof, and

          (ii) issue, upon the request of any Holder or purchaser of Initial
     Senior Subordinated Notes covered by any Shelf Registration Statement
     contemplated by this Agreement, Senior Subordinated Exchange Notes having
     an aggregate principal amount equal to the aggregate principal amount of
     Initial Senior Subordinated Notes sold pursuant to the Shelf Registration
     Statement and surrendered to the Authority for cancellation. The Authority
     shall register Senior Subordinated Exchange Notes on the Shelf Registration
     Statement for this purpose and issue the Senior Subordinated Exchange Notes
     to the purchaser(s) of securities subject to the Shelf Registration
     Statement in the names as such purchaser(s) shall designate.

     (c) General Provisions. In connection with any Registration Statement and
any related Prospectus required by this Agreement, the Authority shall:

          (i) use its best efforts to keep such Registration Statement
     continuously effective and provide all requisite financial statements for
     the period specified in Section 3 or 4 of this Agreement, as applicable.
     Upon the occurrence of any event that would cause any such Registration
     Statement or the Prospectus contained therein (A) to contain an untrue
     statement of material fact or omit to state any material fact necessary to
     make the statements therein not misleading or (B) not to be effective and
     usable for resale of Transfer Restricted Securities during the period
     required by this Agreement, the Authority shall file promptly an
     appropriate amendment to such Registration Statement curing such defect,
     and, if Commission review is required, use its best efforts to cause such
     amendment to be declared effective as soon as practicable;

          (ii) prepare and file with the Commission such amendments and
     post-effective amendments to the applicable Registration Statement as may
     be necessary to keep such


                                       7
<PAGE>
 
     Registration Statement effective for the applicable period set forth in
     Section 3 or 4 hereof, as the case may be, cause the Prospectus to be
     supplemented by any required Prospectus supplement, and as so supplemented
     to be filed pursuant to Rule 424 under the Act, and to comply fully with
     Rules 424, 430A and 462, as applicable, under the Act in a timely manner;
     and comply with the provisions of the Act with respect to the disposition
     of all securities covered by such Registration Statement during the
     applicable period in accordance with the intended method or methods of
     distribution by the sellers thereof set forth in such Registration
     Statement or supplement to the Prospectus;

          (iii) advise each Holder promptly and, if requested by such Holder,
     confirm such advice in writing, (A) when the Prospectus or any Prospectus
     supplement or post-effective amendment has been filed, and, with respect to
     any applicable Registration Statement or any post-effective amendment
     thereto, when the same has become effective, (B) of any request by the
     Commission for amendments to the Registration Statement or amendments or
     supplements to the Prospectus or for additional information relating
     thereto, (C) of the issuance by the Commission of any stop order suspending
     the effectiveness of the Registration Statement under the Act or of the
     suspension by any state securities commission of the qualification of the
     Transfer Restricted Securities for offering or sale in any jurisdiction, or
     the initiation of any proceeding for any of the preceding purposes, (D) of
     the existence of any fact or the happening of any event that makes any
     statement of a material fact made in the Registration Statement, the
     Prospectus, any amendment or supplement thereto or any document
     incorporated by reference therein untrue, or that requires the making of
     any additions to or changes in the Registration Statement in order to make
     the statements therein not misleading, or that requires the making of any
     additions to or changes in the Prospectus in order to make the statements
     therein, in the light of the circumstances under which they were made, not
     misleading. If at any time the Commission shall issue any stop order
     suspending the effectiveness of the Registration Statement, or any state
     securities commission or other regulatory authority shall issue an order
     suspending the qualification or exemption from qualification of the
     Transfer Restricted Securities under state securities or Blue Sky laws, the
     Authority shall use its best efforts to obtain the withdrawal or lifting of
     such order at the earliest possible time;

          (iv) subject to Section 6(c)(i), if any fact or event contemplated by
     Section 6(c)(iii)(D) above shall exist or have occurred, prepare a
     supplement or post-effective amendment to the Registration Statement or
     related Prospectus or any document incorporated therein by reference or
     file any other required document so that, as thereafter delivered to the
     purchasers of Transfer Restricted Securities, the Prospectus will not
     contain an untrue statement of a material fact or omit to state any
     material fact necessary to make the statements therein, in the light of the
     circumstances under which they were made, not misleading;

          (v) furnish to each Holder in connection with such exchange or sale,
     if any, before filing with the Commission, copies of any Registration
     Statement or any Prospectus included therein or any amendments or
     supplements to any such Registration Statement or Prospectus (including all
     documents incorporated by reference after the initial filing of such
     Registration Statement), which documents will be subject to the review and
     comment of such Holders in connection with such sale, if any, for a period
     of at least five Business Days, and the Authority will use its best efforts
     to reflect in each such Registration Statement or Prospectus or any
     amendment or supplement to any such Registration Statement or Prospectus
     (including all such documents incorporated by reference) when so filed with
     the Commission, such comments proposed by such Holders. A Holder shall be
     deemed to have objected to such filing if such Registration Statement,
     amendment, Prospectus or supplement, as applicable, as proposed to be
     filed, contains an untrue statement of a material fact or omit to state any
     material fact necessary to make the statements therein not misleading or
     fails to comply with the applicable requirements of the Act;


                                       8
<PAGE>
 
          (vi) promptly prior to the filing of any document that is to be
     incorporated by reference into a Registration Statement or Prospectus,
     provide copies of such document to each Holder in connection with such
     exchange or sale, if any, make the Authority's representatives available
     for discussion of such document and other customary due diligence matters,
     and include such information in such document prior to the filing thereof
     as such Holders may reasonably request;

          (vii) make available, at reasonable times, for inspection by each
     Holder and any attorney or accountant retained by such Holders, all
     financial and other records, pertinent corporate documents of the Authority
     and cause the Authority's officers, board members and employees to supply
     all information reasonably requested by any such Holder, attorney or
     accountant in connection with such Registration Statement or any
     post-effective amendment thereto subsequent to the filing thereof and prior
     to its effectiveness;

          (viii) if requested by any Holders in connection with such exchange or
     sale, promptly include in any Registration Statement or Prospectus,
     pursuant to a supplement or post-effective amendment if necessary, such
     information as such Holders may reasonably request to have included
     therein, including, without limitation, information relating to the "Plan
     of Distribution" of the Transfer Restricted Securities, and make all
     required filings of such Prospectus supplement or post-effective amendment
     as soon as practicable after the Authority is notified of the matters to be
     included in such Prospectus supplement or post-effective amendment;

          (ix) furnish to each Holder in connection with such exchange or sale,
     without charge, at least one copy of the Registration Statement, as first
     filed with the Commission, and of each amendment thereto, including all
     documents incorporated by reference therein and all exhibits (including
     exhibits incorporated therein by reference);

          (x) deliver to each Holder without charge, as many copies of the
     Prospectus (including each preliminary prospectus) and any amendment or
     supplement thereto as such Persons reasonably may request; the Authority
     hereby consents to the use (in accordance with law) of the Prospectus and
     any amendment or supplement thereto by each selling Holder in connection
     with the offering and the sale of the Transfer Restricted Securities
     covered by the Prospectus or any amendment or supplement thereto;

          (xi) upon the request of any Holder, enter into such agreements
     (including underwriting agreements) and make such representations and
     warranties and take all such other actions in connection therewith in order
     to expedite or facilitate the disposition of the Transfer Restricted
     Securities pursuant to any applicable Registration Statement contemplated
     by this Agreement as may be reasonably requested by any Holder in
     connection with any sale or resale pursuant to any applicable Registration
     Statement. In such connection, the Authority shall

               (A) upon request of any Holder, furnish (or in the case of
          paragraphs (2) and (3), use its best efforts to cause to be furnished)
          to each Holder, upon Consummation of the Exchange Offer or upon the
          effectiveness of the Shelf Registration Statement, as the case may be:

                    (1) a certificate, dated such date, signed on behalf of the
               Authority by the Chairman of the Management Board confirming, as
               of the date thereof, the matters set forth in Section 6(d) of the
               Purchase Agreement and such other similar matters as such Holders
               may reasonably request;

                    (2) an opinion, dated the date of Consummation of the
               Exchange Offer or the date of effectiveness of the Shelf
               Registration Statement, as the case may be, of counsel for the
               Authority covering such matters as such Holder may reasonably
               request and are customarily given in similar offerings; and

               Consummation of the Exchange Offer, or as of the date of
               effectiveness of the Shelf Registration Statement, as the case
               may be, from the Authority's independent accountants, in the
               customary form and covering matters of the type customarily
               covered in comfort letters to underwriters in connection with
               underwritten offerings, and affirming the matters set forth in
               the comfort letters delivered pursuant to Section 6(e) of the
               Purchase Agreement; and

               (B) deliver such other documents and certificates as may be
          reasonably requested by the selling Holders to evidence compliance
          with the matters covered in clause (A) above and with any customary
          conditions contained in the any agreement entered into by the
          Authority pursuant to this clause (xi);

          (xii) prior to any public offering of Transfer Restricted Securities,
     cooperate with the selling Holders and their counsel in connection with the
     registration and qualification of the Transfer Restricted Securities under
     the securities or Blue Sky laws of such jurisdictions as the selling
     Holders may request and do any and all other acts or things necessary or
     advisable to enable the disposition in such jurisdictions of the Transfer
     Restricted Securities covered by the applicable Registration Statement;
     provided, however, that the Authority shall not be required to register or
     qualify as a foreign corporation where it is not now so qualified or to
     take any action that would subject it to the service of process in suits or
     to taxation, other than as to matters and transactions relating to the
     Registration Statement, in any jurisdiction where it is not now so subject;

          (xiii) in connection with any sale of Transfer Restricted Securities
     that will result in such securities no longer being Transfer Restricted
     Securities, cooperate with the Holders to facilitate the timely preparation
     and delivery of certificates representing Transfer Restricted Securities to
     be sold and not bearing any restrictive legends; and to register such
     Transfer Restricted Securities in such denominations and such names as the
     selling Holders may request at least two Business Days prior to such sale
     of Transfer Restricted Securities;

          (xiv) use its best efforts to cause the disposition of the Transfer
     Restricted Securities covered by the Registration Statement to be
     registered with or approved by such other governmental agencies or

     consummate the disposition of such Transfer Restricted Securities, subject
     to the proviso contained in clause (xii) above;

          (xv) provide a CUSIP number for all Transfer Restricted Securities not
     later than the effective date of a Registration Statement covering such

     rules and regulations of the Commission, and make generally available to
     its security holders with regard to any applicable Registration Statement,
     as soon as practicable, a consolidated earnings statement meeting the
     requirements of Rule 158 (which need not be audited) covering a 12-month
     period beginning after the effective date of the Registration Statement (as
     such term is defined in paragraph (c) of Rule 158 under the Act);

          (xvii) cause the Senior Subordinated Notes Indenture to be qualified
     under the TIA not later than the effective date of the first Registration
     Statement required by this Agreement and, in connection therewith,
     cooperate with the Trustee and the Holders to effect such changes to the
     Senior Subordinated Notes Indenture as may be required for such Senior
     Subordinated Notes


                                       10

     Indenture to be so qualified in accordance with the terms of the TIA; and
     execute and use its best efforts to cause the Trustee to execute, all
     documents that may be required to effect such changes and all other forms

     Senior Subordinated Notes Indenture to be so qualified in a timely manner;
     and

          (xviii) provide promptly to each Holder, upon request, each document
     filed with the Commission pursuant to the requirements of Section 13 or
     Section 15(d) of the Exchange Act.

     (d) Restrictions on Holders. Each Holder agrees by acquisition of a
Transfer Restricted Security that, upon receipt of the notice referred to in
Section 6(c)(iii)(C) or any notice from the Authority of the existence of any
fact of the kind described in Section 6(c)(iii)(D) hereof (in each case, a
"Suspension Notice"), such Holder will forthwith discontinue disposition of
Transfer Restricted Securities pursuant to the applicable Registration Statement
until (i) such Holder has received copies of the supplemented or amended
Prospectus contemplated by Section 6(c)(iv) hereof, or (ii) such Holder is
advised in writing by the Authority that the use of the Prospectus may be
resumed, and has received copies of any additional or supplemental filings that
are incorporated by reference in the Prospectus (in each case, the
"Recommencement Date"). Each Holder receiving a Suspension Notice hereby agrees
that it will either (i) destroy any Prospectuses, other than permanent file
copies, then in such Holder's possession which have been replaced by the
Authority with more recently dated Prospectuses or (ii) deliver to the Authority
(at the Authority's expense) all copies, other than permanent file copies, then
in such Holder's possession of the Prospectus covering such Transfer Restricted
Securities that was current at the time of receipt of the Suspension Notice. The
time period regarding the effectiveness of such Registration Statement set forth
in Section 3 or 4 hereof, as applicable, shall be extended by a number of days
equal to the number of days in the period from and including the date of
delivery of the Suspension Notice to the date of delivery of the Recommencement
Date.

     (e) Underwritten Offerings. No Holder may participate in any underwritten
Shelf Registration Statement hereunder unless such Holder (i) agrees to sell

underwriting arrangements entered into in connection therewith and (ii)
completes and executes all questionnaires, powers of attorney, indemnities,
underwriting agreements and other documents reasonably required under the terms
of such underwriting arrangements.

Authority (including the expenses of any special audit and comfort letters
required by or incident to such performance).

     The Authority will, in any event, bear its internal expenses (including,
without limitation, all salaries and expenses of its officers and employees
performing legal or accounting duties), the expenses of any annual audit and the
fees and expenses of any person, including special experts, retained by the
Authority.

     (b) In connection with any Registration Statement required by this
Agreement (including, without limitation, the Exchange Offer Registration
Statement and the Shelf Registration Statement), the


                                       11
<PAGE>
 
Authority will reimburse the Initial Purchasers and the Holders of Transfer
Restricted Securities who are tendering Initial Senior Subordinated Notes into
the Exchange Offer and/or selling or reselling Initial Senior Subordinated Notes
or Senior Subordinated Exchange Notes pursuant to the "Plan of Distribution"
contained in the Exchange Offer Registration Statement or the Shelf Registration
Statement, as applicable, for the reasonable fees and disbursements of not more
than one counsel, as may be chosen by the Holders of a majority in principal
amount of the Transfer Restricted Securities for whose benefit such Registration
Statement is being prepared.

     Notwithstanding the foregoing, the Holders of any Initial Senior
Subordinated Notes or Exchange Senior Subordinated Notes being registered on the
Shelf Registration Statement shall pay all agency or brokerage fees and
commissions and underwriting discounts and commissions attributable to the sale
of such Initial Senior Subordinated Notes or Exchange Senior Subordinated Notes
and the fees and disbursements of any counsel retained by such Holders other
than counsel referred to above.

SECTION 8. INDEMNIFICATION

     (a) The Authority agrees to indemnify and hold harmless each Holder, its
directors, officers and each person, if any, who controls such Holder (within
the meaning of Section 15 of the Act or Section 20 of the Exchange Act), from
and against any and all losses, claims, damages, liabilities, judgments,
(including without limitation, any legal or other expenses incurred in
connection with investigating or defending any matter, including any action that
could give rise to any such losses, claims, damages, liabilities or judgments)
caused by any untrue statement or alleged untrue statement of a material fact
contained in any Registration Statement, preliminary prospectus or Prospectus
(or any amendment or supplement thereto) provided by the Authority to any Holder
or any prospective purchaser of Senior Subordinated Exchange Notes or registered
Initial Senior Subordinated Notes, or caused by any omission or alleged omission
to state therein a material fact required to be stated therein or necessary to
make the statements therein not misleading, except insofar as such losses,
claims, damages, liabilities or judgments are caused by an untrue statement or
omission or alleged untrue statement or omission that is based upon information
relating to any of the Holders furnished in writing to the Authority by any of
the Holders.

     (b) Each Holder of Transfer Restricted Securities agrees, severally and not
jointly, to indemnify and hold harmless the Authority and its directors and
officers, and each person, if any, who controls (within the meaning of Section
15 of the Act or Section 20 of the Exchange Act) the Authority to the same
extent as the foregoing indemnity from the Authority set forth in section (a)
above, but only with reference to information relating to such Holder furnished
in writing to the Authority by such Holder expressly for use in any Registration
Statement. In no event shall any Holder, its directors, officers or any person
who controls such Holder be liable or responsible for any amount in excess of
the amount by which the total amount received by such Holder with respect to its
sale of Transfer Restricted Securities pursuant to a Registration Statement
exceeds (i) the amount paid by such Holder for such Transfer Restricted
Securities and (ii) the amount of any damages that such Holder, its directors,
officers or any person who controls such Holder has otherwise been required to
pay by reason of such untrue or alleged untrue statement or omission or alleged
omission.

     (c) In case any action shall be commenced involving any person in respect
of which indemnity may be sought pursuant to Section 8(a) or 8(b) (the
"indemnified party"), the indemnified party shall promptly notify the person
against whom such indemnity may be sought (the "indemnifying person") in writing
and the indemnifying party shall assume the defense of such action, including
the employment of counsel reasonably satisfactory to the indemnified party and
the payment of all fees and expenses of such counsel, as incurred (except that
in the case of any action in respect of which indemnity may be sought pursuant
to both Sections 8(a) and 8(b), a Holder shall not be required to assume the
defense of such action pursuant to this Section 8(c), but may employ separate
counsel and participate in the defense thereof, but the fees and expenses of
such counsel, except as provided below, shall be at the expense of the Holder).
Any indemnified party shall have the right to employ separate counsel in any
such action and participate in the


                                       12
<PAGE>
 
defense thereof, but the fees and expenses of such counsel shall be at the
expense of the indemnified party unless (i) the employment of such counsel shall
have been specifically authorized in writing by the indemnifying party, (ii) the
indemnifying party shall have failed to assume the defense of such action or
employ counsel reasonably satisfactory to the indemnified party or (iii) the
named parties to any such action (including any impleaded parties) include both
the indemnified party and the indemnifying party, and the indemnified party
shall have been advised by such counsel that there may be one or more legal
defenses available to it which are different from or additional to those
available to the indemnifying party (in which case the indemnifying party shall
not have the right to assume the defense of such action on behalf of the
indemnified party). In any such case, the indemnifying party shall not, in
connection with any one action or separate but substantially similar or related
actions in the same jurisdiction arising out of the same general allegations or
circumstances, be liable for the fees and expenses of more than one separate
firm of attorneys (in addition to any local counsel) for all indemnified parties
and all such fees and expenses shall be reimbursed as they are incurred. Such
firm shall be designated in writing by a majority of the Holders, in the case of
the parties indemnified pursuant to Section 8(a), and by the Authority, in the
case of parties indemnified pursuant to Section 8(b). The indemnifying party
shall indemnify and hold harmless the indemnified party from and against any and
all losses, claims, damages, liabilities and judgments by reason of any
settlement of any action (i) effected with its written consent or (ii) effected
without its written consent if the settlement is entered into more than 20
Business Days after the indemnifying party shall have received a request from
the indemnified party for reimbursement for the fees and expenses of counsel (in
any case where such fees and expenses are at the expense of the indemnifying
party) and, prior to the date of such settlement, the indemnifying party shall
have failed to comply with such reimbursement request. No indemnifying party
shall, without the prior written consent of the indemnified party, effect any
settlement or compromise of, or consent to the entry of judgment with respect
to, any pending or threatened action in respect of which the indemnified party
is or could have been a party and indemnity or contribution may be or could have
been sought hereunder by the indemnified party, unless such settlement,
compromise or judgment (i) includes an unconditional release of the indemnified
party from all liability on claims that are or could have been the subject
matter of such action and (ii) does not include a statement as to or an
admission of fault, culpability or a failure to act, by or on behalf of the
indemnified party.

     (d) To the extent that the indemnification provided for in this Section 8
is unavailable to an indemnified party in respect of any losses, claims,
damages, liabilities or judgments referred to therein, then each indemnifying
party, in lieu of indemnifying such indemnified party, shall contribute to the
amount paid or payable by such indemnified party as a result of such losses,
claims, damages, liabilities or judgments (i) in such proportion as is
appropriate to reflect the relative benefits received by the Authority, on the
one hand, and the Holders, on the other hand, from their sale of Transfer
Restricted Securities or (ii) if the allocation provided by clause 8(d)(i) is
not permitted by applicable law, in such proportion as is appropriate to reflect
not only the relative benefits referred to in clause 8(d)(i) above but also the
relative fault of the Authority, on the one hand, and of the Holder, on the
other hand, in connection with the statements or omissions which resulted in
such losses, claims, damages, liabilities or judgments, as well as any other
relevant equitable considerations. The relative fault of the Authority, on the
one hand, and of the Holder, on the other hand, shall be determined by reference
to, among other things, whether the untrue or alleged untrue statement of a
material fact or the omission or alleged omission to state a material fact
relates to information supplied by the Authority, on the one hand, or by the
Holder, on the other hand, and the parties' relative intent, knowledge, access
to information and opportunity to correct or prevent such statement or omission.
The amount paid or payable by a party as a result of the losses, claims,
damages, liabilities and judgments referred to above shall be deemed to include,
subject to the limitations set forth in the second paragraph of Section 8(a),
any legal or other fees or expenses reasonably incurred by such party in
connection with investigating or defending any action or claim.

     The Authority and each Holder agree that it would not be just and equitable
if contribution pursuant to this Section 8(d) were determined by pro rata
allocation (even if the Holders were treated as one entity for such purpose) or
by any other method of allocation which does not take account of the


                                       13
<PAGE>
 
equitable considerations referred to in the immediately preceding paragraph. The
amount paid or payable by an indemnified party as a result of the losses,
claims, damages, liabilities or judgments referred to in the immediately
preceding paragraph shall be deemed to include, subject to the limitations set
forth above, any legal or other expenses reasonably incurred by such indemnified
party in connection with investigating or defending any matter, including any
action that could have given rise to such losses, claims, damages, liabilities
or judgments. Notwithstanding the provisions of this Section 8, no Holder, its
directors, its officers or any person, if any, who controls such Holder shall be
required to contribute, in the aggregate, any amount in excess of the amount by
which the total received by such Holder with respect to the sale of Transfer
Restricted Securities pursuant to a Registration Statement exceeds (i) the
amount paid by such Holder for such Transfer Restricted Securities and (ii) the
amount of any damages which such Holder has otherwise been required to pay by
reason of such untrue or alleged untrue statement or omission or alleged
omission. No person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation. The Holders'
obligations to contribute pursuant to this Section 8(d) are several in
proportion to the respective principal amount of Transfer Restricted Securities
held by each Holder hereunder and not joint.

SECTION 9. RULE 144A and RULE 144

     The Authority agrees with each Holder, for so long as any Transfer
Restricted Securities remain outstanding and during any period in which the
Authority (i) is not subject to Section 13 or 15(d) of the Exchange Act, to make
available, upon request of any Holder, to such Holder or beneficial owner of
Transfer Restricted Securities in connection with any sale thereof and any
prospective purchaser of such Transfer Restricted Securities designated by such
Holder or beneficial owner, the information required by Rule 144A(d)(4) under
the Act in order to permit resales of such Transfer Restricted Securities
pursuant to Rule 144A, and (ii) is subject to Section 13 or 15 (d) of the
Exchange Act, to make all filings required thereby in a timely manner in order
to permit resales of such Transfer Restricted Securities pursuant to Rule 144.

SECTION 10. CONSENT TO SUIT

     The Authority waives its sovereign immunity from unconsented suit, whether
such suit be brought in law or in equity, or in administrative proceedings or
proceedings in arbitration, to permit the commencement, maintenance, and
enforcement of any action, by any person with standing to maintain an action, to
interpret or enforce the terms of this Agreement, and to enforce and execute any
judgment resulting therefrom against the Authority or the assets of the
Authority. Notwithstanding any other provision of law or canon of construction,
the Authority intends this waiver to be interpreted liberally to permit the full
litigation of disputes arising under or out of this Agreement. Without limiting
the generality of the foregoing, the Authority waives its immunity from
unconsented suit to permit the maintenance of the following actions:

          (i) Courts. The Authority waives its immunity from unconsented suit to
     permit any court of competent jurisdiction to: (i) enforce and interpret
     the terms of this Agreement, and award and enforce the award of damages
     owing as a consequence of a breach thereof, whether such award is the
     product of litigation, administrative proceedings or arbitration; (ii)
     determine whether any consent or approval of the Authority has been
     improperly granted or unreasonably withheld; (iii) enforce any judgment
     prohibiting the Authority from taking any action, or mandating or
     obligating the Authority to take any action, including a judgment
     compelling the Authority to submit to binding arbitration; and (iv)
     adjudicate any claim under the Indian Civil Rights Act of 1968, 25 U.S.C.
     ss. 1302 (or any successor statute).

          (ii) Arbitration. The Authority waives its immunity from unconsented
     suit to permit arbitrators, appointed and acting under the commercial
     arbitration rules of the American Arbitration


                                       14
<PAGE>
 
     Association, whenever and to the extent any agreement to submit a matter to
     arbitration is made by the Authority, to: (i) enforce and interpret the
     terms of this Agreement and to award and enforce the award of any damages
     owing as a consequence thereof; (ii) determine whether any consent or
     approval of the Authority has been unreasonably withheld; and (iii) enforce
     any judgment prohibiting the Authority from taking any action, or mandating
     or obligating the Authority to take any action, including a judgment
     compelling the Authority to submit to binding arbitration.

SECTION 11. MISCELLANEOUS

     (a) Remedies. The Authority acknowledges and agrees that any failure by the
Authority to comply with its obligations under Sections 3 and 4 hereof may
result in material irreparable injury to the Initial Purchasers or the Holders
for which there is no adequate remedy at law, that it will not be possible to
measure damages for such injuries precisely and that, in the event of any such
failure, the Initial Purchasers or any Holder may obtain such relief as may be
required to specifically enforce the Authority's obligations under Sections 3
and 4 hereof. The Authority further agrees to waive the defense in any action
for specific performance that a remedy at law would be adequate.

     (b) No Inconsistent Agreements. The Authority will not, on or after the
date of this Agreement, enter into any agreement with respect to its securities
that is inconsistent with the rights granted to the Holders in this Agreement or
otherwise conflicts with the provisions hereof. The rights granted to the
Holders hereunder do not in any way conflict with and are not inconsistent with
the rights granted to the holders of the Authority's securities under any
agreement in effect on the date hereof.

     (c) Amendments and Waivers. The provisions of this Agreement may not be
amended, modified or supplemented, and waivers or consents to or departures from
the provisions hereof may not be given unless (i) in the case of Section 5
hereof and this Section 11(c)(i), the Authority has obtained the written consent
of Holders of all outstanding Transfer Restricted Securities and (ii) in the
case of all other provisions hereof, the Authority has obtained the written
consent of Holders of a majority of the outstanding principal amount of Transfer
Restricted Securities (excluding Transfer Restricted Securities held by the
Authority or its Affiliates). Notwithstanding the foregoing, a waiver or consent
to departure from the provisions hereof that relates exclusively to the rights
of Holders whose Transfer Restricted Securities are being tendered pursuant to
the Exchange Offer, and that does not affect directly or indirectly the rights
of other Holders whose Transfer Restricted Securities are not being tendered
pursuant to such Exchange Offer, may be given by the Holders of a majority of
the outstanding principal amount of Transfer Restricted Securities subject to
such Exchange Offer.

     (d) Third Party Beneficiary. The Holders shall be third party beneficiaries
to the agreements made hereunder between the Authority, on the one hand, and the
Initial Purchasers, on the other hand, and shall have the right to enforce such
agreements directly to the extent they may deem such enforcement necessary or
advisable to protect its rights or the rights of Holders hereunder.

     (e) Notices. All notices and other communications provided for or permitted
hereunder shall be made in writing by hand-delivery, first-class mail
(registered or certified, return receipt requested), telex, telecopier, or air
courier guaranteeing overnight delivery:

          (i) if to a Holder, at the address set forth on the records of the
     Registrar under the Senior Subordinated Notes Indenture, with a copy to the

Holders; provided, that nothing herein shall be deemed to permit any assignment,
transfer or other disposition of Transfer Restricted Securities in violation of
the terms hereof or of the Purchase Agreement or the Senior Subordinated Notes
Indenture. If any transferee of any Holder shall acquire Transfer Restricted
Securities in any manner, whether by operation of law or otherwise, such

Agreement, and by taking and holding such Transfer Restricted Securities such
person shall be conclusively deemed to have agreed to be bound by and to perform

                              _____________, 1999



Mohegan Tribal Gaming Authority
1 Mohegan Sun Boulevard
Uncasville, CT 06382


Ladies and Gentlemen:

        This firm has acted as special counsel to the Mohegan Tribe of Indians
of Connecticut (the "Tribe") and the Mohegan Tribal Gaming Authority (the
"Authority"), an instrumentality of the Tribe, in connection with its
Registration Statement on Form S-4, (the "Registration Statement"), filed with
the Securities and Exchange Commission relating to the proposed offering of up
to $200,000,000 in aggregate principal amount of 8-1/8% Senior Notes due January
1, 2006 (the "Senior Exchange Notes") in exchange for up to $200,000,000 in
aggregate principal amount of the Authority's outstanding 8-1/8% Senior Notes
due January 1, 2006 (the "Senior Notes") and to the proposed offering of up to
$300,000,000 in aggregate principal amount of 8-3/4% Senior Subordinated Notes
due January 1, 2009 (the "Senior Subordinated Exchange Notes" and together with
the Senior Exchange Notes, the "Exchange Notes") in exchange for up to
$300,000,000 in aggregate principal amount of the Authority's outstanding 8-3/4%
Senior Subordinated Notes due January 1, 2009 (the "Senior Subordinated Notes").
This opinion letter is furnished to you at your request to enable you to fulfill
the requirements of Item 601(b)(5) of Regulation S-K, 17 C.F.R.
(S)229.601(b)(5), in connection with the Registration Statement.

        For purposes of this opinion letter, we have examined copies of the
following documents:

        1.  An executed copy of the Registration Statement.

        2.  An executed copy of the Senior Notes Indenture dated March 3, 1999
            (the "Senior Notes Indenture"), by and between the Authority and
            First Union National Bank, including the form of Exchange

            Note to be issued pursuant thereto, as filed as Exhibit 4.2 to the
            Registration Statement.

        3.  An executed copy of the Indenture dated March 3, 1999 (the "Senior
            Subordinated Notes Indenture"), by and between the Authority and
            State Street Bank and Trust Company, including the form of Exchange
            Note to be issued pursuant thereto, as filed as Exhibit 4.7 to the
            Registration Statement.

        4.  The Constitution of the Mohegan Tribe, as certified by the Recording
            Secretary of the Management Board of the Authority on the date
            hereof as being complete, accurate and in effect.

        5.  The Mohegan Tribal Ordinance No. 95-2 "And Ordinance Establishing
            the Mohegan Tribal Gaming Authority" dated July 15, 1995.

        6.  Resolutions of the Management Board of the Authority adopted on
            February 18, 1999 as certified by the Recording Secretary of the
            Management Board of the Authority on the date hereof as being
            complete, accurate and in effect, relating to the issuance and sale
            of the Exchange Notes and arrangements in connection therewith.

        In our examination of the aforesaid documents, we have assumed the
genuineness of all signatures, the legal capacity of all natural persons, the
authenticity, accuracy and completeness of all documents submitted to us, and
the conformity with the original documents of all documents submitted to us as
certified, telecopied, photostatic or reproduced copies. This opinion letter is
given, and all statements herein are made, in the context of the foregoing.

        This opinion letter is based as to matters of law solely on applicable
provisions of the contract law of the State of New York (but not including any
statutes, ordinances, administrative decisions, rules or regulations of any
political subdivision of the State of New York). We express no opinion herein as
to any other laws, statutes, ordinances, rules or regulations.

        Based upon, subject to and limited by the foregoing, we are of the
opinion that the Exchange Notes have been duly authorized on behalf of the
Authority and that, (i) following the effectiveness of the Registration
Statement and receipt by the Authority of the Senior Notes in exchange for the
Senior Exchange 
<PAGE>
 
Mohegan Tribal Gaming Authority
______________, 1999
Page 3


Notes and receipt by the Authority of the Senior Subordinated Notes in exchange
for the Senior Subordinated Exchange Notes as specified in the resolutions of
the Management Board referred to above, and (ii) assuming due execution,
authentication, issuance and delivery of the Senior Exchange Notes and Senior
Subordinated Exchange Notes as provided in the Senior Notes Indenture and Senior
Subordinated Notes Indenture (together, the "Indentures"), respectively, both
sets of Exchange Notes will constitute valid and binding obligations of the
Authority entitled to the benefits of the Indentures and enforceable in
accordance with their terms, except as the enforcement thereof may be limited by
bankruptcy, insolvency, reorganization, moratorium or other laws affecting
creditors' rights (including, without limitation, the effect of statutory and
other laws regarding fraudulent conveyances, fraudulent transfers and
preferential transfers) and as may be limited by the exercise of judicial
discretion and the application of principles of equity including without
limitation, requirements of good faith, fair dealing, conscionability and
materiality (regardless of whether the Exchange Notes are considered in a
proceeding in equity or at law).

        The Opinion expressed in the Paragraph above shall be understood to mean
        ========================================================================
only that (i) if there is a default in performance of an obligation, (ii) if a 
==============================================================================
failure to pay or other damage can be shown and (iii) if the defaulting party
=============================================================================
can be brought into a court which will hear the case and apply the governing
============================================================================
law, then, subject to the availability of defenses, and to the exceptions set
=============================================================================
forth in the Paragraph above, the court will provide a money damage (or perhaps 
===============================================================================

limiting the scope and nature of each Lender's participation in any Letter of
Credit, to the extent that the Issuing Lender has not been reimbursed by
Borrower for any payment required to be made by the Issuing Lender under any
Letter of Credit, each Lender shall, pro rata according to its Pro Rata Share,
reimburse the Issuing Lender promptly upon demand for the amount of such payment
through the Administrative Agent.  The obligation of each Lender to so reimburse
the Issuing Lender shall be absolute and unconditional and shall not be affected
by the occurrence of an Event of Default or any other occurrence or event.  Any
such reimbursement shall not relieve or otherwise impair the obligation of
Borrower to reimburse the Issuing Lender for the amount of any payment made by
the Issuing Lender under any Letter of Credit together with interest as
hereinafter provided.

          (d)  Borrower agrees to pay to the Issuing Lender through the
Administrative Agent an amount equal to any payment made by the Issuing Lender
with respect to each Letter of Credit upon the date of each drawing thereunder,
together with interest on such amount from the date of any payment made by the
Issuing Lender at the Default Rate (provided that, subject to the terms and
                                    -------- ----                          
conditions hereof, Borrower may request a Base Rate Loan in accordance with this
Agreement to finance such amounts at the rate ordinarily applicable to Base Rate
Loans).  The principal amount of any such payment shall be used to reimburse the
Issuing Lender for the payment made by it under the Letter of Credit.  Each
Lender that has reimbursed the Issuing Lender pursuant to Section 2.4(c) for its
Pro-Rata Share of any payment made by the Issuing Lender under a Letter of
Credit shall thereupon acquire a pro-rata participation, to the extent of such
reimbursement, in the claim of the Issuing Lender against Borrower under this
Section 2.4(d) and shall share, in accordance with that pro-rata participation,
in any payment (including any payment of interest with respect 

                                      -33-

thereto) made by Borrower with respect to such claim, and the Administrative
Agent shall remit to each such Lender its Pro Rata Share thereof in immediately
available funds.

          (e)  If Borrower fails to make the payment required by Section 2.4(d)
upon demand, in lieu of the reimbursement to the Issuing Lender under Section
2.4(c) the Issuing Lender may (but is not required to) without notice to or the
consent of Borrower, instruct the Administrative Agent to cause Advances to be
made by the Lenders under the Commitment in accordance with their Pro Rata
Shares in an aggregate amount equal to the amount paid by the Issuing Lender
with respect to that Letter of Credit and, for this purpose, the conditions
precedent set forth in Article 10 shall not apply.  The proceeds of such
Advances shall be paid to the Issuing Lender to reimburse it for the payment
made by it under the Letter of Credit.  Such Advances shall be payable upon
demand and shall bear interest at the Default Rate.

          (f)  The issuance of any supplement, modification, amendment, renewal,
or extension to or of any Letter of Credit shall be treated in all respects the
same as the issuance of a new Letter of Credit.

          (g)  The obligation of Borrower to pay to the Issuing Lender the
amount of any payment made by the Issuing Lender under any Letter of Credit
shall be absolute, unconditional, and irrevocable, subject only to performance
by the Issuing Lender of its obligations to Borrower under Connecticut Uniform
Commercial Code Section 42a-5-109.  Without limiting the foregoing, Borrower's
obligations shall not be affected by any of the following circumstances:

               (i)    any lack of validity or enforceability of the Letter of
     Credit, this Agreement, or any other agreement or instrument relating
     thereto;

     from the Letter of Credit, this Agreement, or any other agreement or
     instrument relating thereto;

               (iii)  the existence of any claim, setoff, defense, or other
     rights which Borrower may have at any time against the Issuing Lender, the

     or any other Person, whether in connection with the Letter of   Credit,
     this Agreement, or any other agreement or instrument relating thereto, or
     any unrelated transactions;

     under the Letter of Credit proving to be forged, fraudulent, invalid, or

     insufficient in any respect or any statement therein being untrue or
     inaccurate in any respect whatsoever;

               (v)    payment by the Issuing Lender in good faith under the
     Letter of Credit against presentation of a draft or any accompanying
     document which does not strictly comply with the terms of the Letter of
     Credit;

               (vi)   the existence, character, quality, quantity, condition,
     packing, value or delivery of any property purported to be represented by
     documents presented in connection with any Letter of Credit or for any
     difference between any such property and the character, quality, quantity,

     deliveries of property as described in documents presented in connection
     with any Letter of Credit or the existence, nature and extent of any
     insurance relative thereto;

               (viii) the solvency or financial responsibility of any party
     issuing any documents in connection with a Letter of Credit;

               (ix)   any failure or delay in notice of shipments or arrival of
     any property;

               (x)    any error in the transmission of any message relating to a
     Letter of Credit not caused by the Issuing Lender, or any delay or
     interruption in any such message;

               (xi)   any error, neglect or default of any correspondent of  the
     Issuing Lender in connection with a Letter of Credit;

               (xii)  any consequence arising from acts of God, war,
     insurrection, civil unrest, disturbances, labor disputes, emergency
     conditions or other causes beyond the control of the Issuing Lender;

               (xiii) so long as the Issuing Lender in good faith determines
     that the contract or document appears to comply with the terms of the
     Letter of Credit, the form, accuracy, genuineness or legal effect of any
     contract or document referred to in any document submitted to the Issuing
     Lender in connection with a Letter of Credit; and

     observed general banking usage, customs or practices, any other

to the Administrative Agent pursuant to Section 12.6, mutatis mutandis.

automatically reduce by the Reduction Amount on each Reduction Date.

          3.6  Voluntary Reduction of Commitment.  Borrower shall have the

right, at any time and from time to time, without penalty or charge, upon at
least five Business Days prior written notice to the Administrative Agent,
voluntarily to permanently and irrevocably reduce, in aggregate principal
amounts which are not less than $5,000,000 and in an integral multiple of
$1,000,000, or to terminate, the then undisbursed portion of the Commitment,
provided that (i) any such reduction or termination shall be accompanied by all

accrued and unpaid commitment fees with respect to any portion of the Commitment
being reduced or terminated, and (ii) no such reduction or termination shall
affect the further scheduled reductions of Commitment in accordance with Section

     Borrower may, at any time prior to the date which is the second 
     anniversary of the Closing Date, request in writing that the then 
     effective Commitment be increased to an amount which is not greater than 
                                                                   ----- 
     $500,000,000 minus the amount of any reductions to the Commitment which
     have then occurred pursuant to Sections 2.5 or 2.6, in accordance with the
     provisions of this Section. Any request under this Section shall be
     submitted by Borrower to the Lenders through the Administrative Agent not
     less than thirty days prior to the proposed increase, specify the proposed
     effective date and amount of such increase and be accompanied by a
     Certificate signed by a Senior Officer of Borrower (and consented to by the
     Tribe acting through a Senior Officer), stating that no Default or Event of
     Default exists as of the date of the request or will result from the
     requested increase. Borrower may also specify any fees offered to those
     Lenders which agree to an increase in the amount of their Pro Rata Share of
     the Commitment (which fees may be variable based upon the amount which any
     such Lender is willing to assume as an increase to the amount of its Pro
     Rata Share of the increased Commitment). The consent of the Lenders, as
     such, shall not be required for an increase in the amount of the Commitment
     pursuant to this Section.

          (b)  Each Lender may approve or reject a request for an increase in
the amount of the Commitment in its sole and absolute discretion and, absent an
affirmative written response within thirty days after receipt of such request,
shall be

                                      -36-

deemed to have rejected the request. The rejection of such a request by any
number of Lenders shall not affect Borrower's right to increase the Commitment
pursuant to this Section.

     (c)  In responding to a request under this Section, each Lender which is
willing to increase the amount of its Pro Rata Share of the increased Commitment
shall specify the amount of the proposed increase which it is willing to assume.
Each consenting Lender shall be entitled to participate ratably (based on its
Pro Rata Share of the Commitment before such increase) in any resulting increase
in the Commitment, subject to the right of the Administrative Agent to adjust
allocations of the increased Commitment so as to result in the amounts of the
Pro Rata Shares of the Lenders being in  integral multiples of $100,000.

     (d)  If the aggregate principal amount offered to be assumed by the
consenting Lenders is less than the amount requested, Borrower may (i) reject
the proposed increase in its entirety, (ii) accept the offered amounts or (iii)
designate new lenders who qualify as Eligible Assignees and which are reasonably
acceptable to the Administrative Agent as additional Lenders hereunder in
accordance with clause (e) of this Section (each, a "New Lender"), which New
Lenders may assume the amount of the increase in the Commitment that has not
been assumed by the consenting Lenders.

     (e)  Each New Lender designated by Borrower and reasonably acceptable to
the Administrative Agent shall become an additional party hereto as a New Lender
concurrently with the effectiveness of the proposed increase in the Commitment
upon its execution of an instrument of joinder to this Agreement which is in
form and substance reasonably acceptable to the Administrative Agent and which,
in any event, contains the representations, warranties, indemnities and other
protections afforded to the Administrative Agent and the other Lenders which
would be granted or made by an Eligible Assignee by means of the execution of an
Assignment Agreement.

     (f)  Subject to the foregoing, any increase to the Commitment requested
under this Section shall be effective as of the date proposed by Borrower and
shall be in the principal amount equal to (i) the amount which consenting
Lenders are willing to assume as increases to the amount of their Pro Rata Share
plus (ii) the amount offered by any New Lenders.  Upon the effectiveness of any
- ----                                                                           
such increase, Borrower shall issue (x) replacement Notes to each affected
Lender and new Notes to each New Lender, and the percentage Pro Rata Shares of
each Lender will be adjusted to give effect to the increase in the Commitment
and set forth in a new Schedule 1.1 issued by the Administrative Agent, (y)
execute and deliver to the Administrative Agent such amendments to the Loan
Documents as the Administrative Agent may reasonably request relating to such
increase, including without limitation an amendment to the Leasehold Mortgage
executed by Borrower and the Tribe reflecting the increase of the amounts
secured thereby, and (z) Borrower shall provide to the Administrative Agent 

                                      -37-

     substance reasonably acceptable to the Administrative Agent, insuring the
     continued priority and perfection of the Leasehold Mortgage.

     3.8  Administrative Agent's Right to Assume Funds Available for Advances.
          -------------------------------------------------------------------  
Unless the Administrative Agent shall have been notified by any Lender prior to
the funding by the Administrative Agent of any Loan that such Lender does not
intend to make available to the Administrative Agent such Lender's Pro Rata
Share of the total amount of such Loan, the Administrative Agent may assume that
such Lender has made such amount available to the Administrative Agent on the
date of the Loan and the Administrative Agent may, in reliance upon such
assumption, make available to Borrower a corresponding amount.  If the
Administrative Agent has made funds available to Borrower based on such
assumption and such corresponding amount is not in fact made available to the
Administrative Agent by such Lender, the Administrative Agent shall be entitled
to recover such corresponding amount on demand from such Lender, which demand
shall be made in a reasonably prompt manner.  If such Lender does not pay such
corresponding amount forthwith upon the Administrative Agent's demand therefor,
the Administrative Agent promptly shall notify Borrower and Borrower shall pay
such corresponding amount to the Administrative Agent.  The Administrative Agent
also shall be entitled to recover from such Lender interest on such
corresponding amount in respect of each day from the date such corresponding
amount was made available by the Administrative Agent to Borrower to the date
such corresponding amount is recovered by the Administrative Agent, at a rate
per annum equal to the Federal Funds Rate.  Nothing herein shall be deemed to
relieve any Lender from its obligation to fulfill its Pro Rata Share or to
prejudice any rights which the Administrative Agent or Borrower may have against
any Lender as a result of any default by such Lender hereunder.

     3.9  Collateral.  The Loans, together with all other Obligations, shall be
          ----------

Agreement shall be secured by the Lien of the Collateral Documents (a) on a pari

all other Obligations.

months thereafter and, in any event, on the last day of the related Interest
Period.  Except as otherwise provided in Section 3.9, the unpaid principal
amount of any LIBOR Loan shall bear interest at a rate per annum equal to the
LIBOR for that LIBOR Loan plus the Applicable Percentage for LIBOR Loans.  While

          (e)  Subject to Section 3.8, the Loans may, at any time and from time
to time, voluntarily be paid or prepaid in whole or in part without premium or
penalty, provided that with respect to any voluntary prepayment of the Loans

          Office to any tax, duty or other charge or cost with respect to any
          LIBOR Advance, any Note or its obligation to make LIBOR Advances, or
          shall change the basis of taxation of payments to any Lender of the
          principal of or interest on any LIBOR Advance or any other amounts due
          under this Agreement in respect of any LIBOR Advance, any Note or its
          obligation to make LIBOR Advances (except for changes in any tax on
                                             ------   
          the overall net income, gross income or gross receipts of such Lender
          or its LIBOR Lending Office);

                                      -41-
<PAGE>
 
                         (ii)  shall impose, modify or deem applicable any
          reserve (including, without limitation, any reserve imposed by the
                   ---------
          Board of Governors of the Federal Reserve System), special deposit or
          similar requirements against assets of, deposits with or for the
          account of, or credit extended by, any Lender or its LIBOR Lending
          Office; or

                         (iii) shall impose on any Lender or its LIBOR Lending
          Office or the Designated Market any other condition affecting any
          LIBOR Advance, any Note, its obligation to make LIBOR Advances or this
          Agreement, or shall otherwise affect any of the same;

     and the result of any of the foregoing, as determined by such Lender,
     increases the cost to such Lender or its LIBOR Lending Office of making or
     maintaining any LIBOR Advance or in respect of any LIBOR Advance, any Note
     or its obligation to make LIBOR Advances or reduces the amount of any sum
     received or receivable by such Lender or its LIBOR Lending Office with
     respect to any LIBOR Advance, any Note or its obligation to make LIBOR
     Advances (assuming such Lender's LIBOR Lending Office had funded 100% of
     its LIBOR Advance in the Designated Market), then, upon demand by such
     Lender (with a copy to the Administrative Agent), Borrower shall pay to
     such Lender such additional amount or amounts as will compensate such
     Lender for such increased cost or reduction (determined as though such
     Lender's LIBOR Lending Office had funded 100% of its LIBOR Advance in the
     Designated Market). A statement of any Lender claiming compensation under
     this subsection, providing supporting calculation, and setting forth the
     additional amount or amounts to be paid to it hereunder shall be conclusive
     in the absence of manifest error. Each Lender agrees to endeavor promptly
     to notify Borrower of any event of which it has actual knowledge occurring
     after the Closing Date, which will entitle such Lender to compensation
     pursuant to this Section, and agrees to designate a different LIBOR Lending
     Office promptly if such designation will avoid the need for or reduce the
     amount of such compensation and will not, in the judgment of such Lender,
     otherwise be disadvantageous to such Lender. If any Lender claims
     compensation under this Section, Borrower may at any time, upon at least
     four LIBOR Business Days' prior notice to the Administrative Agent and such
     Lender and upon payment in full of the amounts provided for in this Section
     through the date of such payment plus any prepayment fee required by
                                      ----
     Section 3.8(d), pay in full the affected LIBOR Advances of such Lender or
     request that such LIBOR Advances be converted to Base Rate Advances.

               (b)  If, after the date hereof, the existence or occurrence of
     any Special Circumstance shall, in the opinion of any Lender, make it
     unlawful, impossible or impracticable for such Lender or its LIBOR Lending
     Office to make, maintain or fund its portion of any LIBOR Loan, or
     materially restrict the ability of such Lender to purchase or sell, or to
     take deposits of, dollars in the Designated Market, or to

                                      -42-
<PAGE>
 
     determine or charge interest rates based upon the LIBOR, and such Lender
     shall so notify the Administrative Agent, then such Lender's obligation to
     make LIBOR Advances shall be suspended for the duration of such illegality,
     impossibility or impracticability and the Administrative Agent forthwith
     shall give notice thereof to the other Lenders and Borrower. Upon receipt
     of such notice, the outstanding principal amount of such Lender's LIBOR
     Advances, together with accrued interest thereon, automatically shall be
     converted to Base Rate Advances on either (1) the last day of the Interest
     Period(s) applicable to such LIBOR Advances if such Lender may lawfully
     continue to maintain and fund such LIBOR Advances to such day(s) or (2)
     immediately if such Lender may not lawfully continue to fund and maintain
     such LIBOR Advances to such day(s), provided that in such event the
                                         --------
     conversion shall not be subject to payment of a prepayment fee under
     Section 3.8(d). In the event that any Lender is unable, for the reasons set
     forth above, to make, maintain or fund its portion of any LIBOR Loan, such
     Lender shall fund such amount as a Base Rate Advance for the same period of
     time, and such amount shall be treated in all respects as a Base Rate
     Advance.

               (c) If, with respect to any proposed LIBOR Loan:

                    (i)  the Administrative Agent reasonably determines that, by
          reason of circumstances affecting the Designated Market generally that
          are beyond the reasonable control of the Lenders, deposits in dollars
          (in the applicable amounts) are not being offered to each of the
          Lenders in the Designated Market for the applicable Interest Period;
          or

                    (ii) the Requisite Lenders advise the Administrative Agent
          that the LIBOR as determined by the Administrative Agent (A) does not
          represent the effective pricing to such Lenders for deposits in
          dollars in the Designated Market in the relevant amount for the
          applicable Interest Period, or (B) will not adequately and fairly
          reflect the cost to such Lenders of making the applicable LIBOR
          Advances;

     then the Administrative Agent forthwith shall give notice thereof to
     Borrower and the Lenders, whereupon until the Administrative Agent notifies
     Borrower that the circumstances giving rise to such suspension no longer
     exist, the obligation of the Lenders to make any future LIBOR Advances
     shall be suspended. If at the time of such notice there is then pending a
     Request for Loan that specifies a LIBOR Loan, such Request for Loan shall
     be deemed to specify a Base Rate Loan.

               (d)  Upon payment or prepayment of any LIBOR Advance (other than
     as the result of a conversion required under Section 3.8(b)), on a day
     other than the last day in the applicable Interest Period (whether
     voluntarily, involuntarily, by reason of acceleration, or otherwise), or
     upon the failure of Borrower to borrow on the

                                      -43-
<PAGE>
 
     date or in the amount specified for a LIBOR Loan in any Request for Loan,
     Borrower shall pay to the appropriate Lender a prepayment fee or failure to
     borrow fee, as the case may be, calculated as follows (and determined as
     though 100% of the LIBOR Advance had been funded in the Designated Market):

                    (i)   principal amount of the LIBOR Advance, times the
                                                                 -----    
          number of days between the date of prepayment or failure to borrow and
          the last day in the applicable Interest Period, divided by 360, times
                                                          ----------      -----
          the applicable Interest Differential; plus
                                                ----

                    (ii)  all actual out-of-pocket expenses (other than those
          taken into account in the calculation of the Interest Differential)
          incurred by the Lender (excluding allocations of any expense internal
                                  ---------    
          to that Lender) and reasonably attributable to such payment,
          prepayment or failure to borrow;

     provided that no prepayment fee or failure to borrow fee shall be payable
     --------    
     (and no credit or rebate shall be required) if the product of the foregoing
     formula is not a positive number. Each Lender's determination of the amount
     of any prepayment fee or failure to borrow fee payable under this Section
     3.8(d) shall be based upon the Administrative Agent's determination of the
     applicable Interest Differential but shall otherwise be conclusive in the
     absence of manifest error.

          4.9  Default Rate. Upon the occurrence and during the continuation of
               ------------      
any Default, the outstanding principal amount of the Loans shall, at the option
of the Requisite Lenders, thereafter bear interest at a rate per annum which is
2% per annum in excess of the otherwise applicable rate, to the fullest extent
permitted by applicable Laws. Upon the occurrence and during the continuation of
any Default or Event of Default, accrued and unpaid interest on past due amounts
(including, without limitation, interest on past due interest) shall be payable
 ---------                                                             
upon demand and shall be compounded quarterly, on the last day of each calendar
quarter, to the fullest extent permitted by applicable Laws.

          4.10 Computation of Interest and Fees. Computation of interest on Base
               --------------------------------   
Rate Loans shall be calculated on the basis of a year of 365 or 366 days, as the
case may be, and the actual number of days elapsed. Computation of interest on
LIBOR Loans and on fees payable under this Agreement shall be calculated on the
basis of a year of 360 days and the actual number of days elapsed. Borrower
acknowledges that such latter calculation method will result in a higher yield
to the Lenders than a method based on a year of 365 or 366 days. Any Loan that
is repaid on the same day on which it is made shall bear interest for one day.

          4.11 Non-Business Days.  If any payment to be made by Borrower or any
               -----------------                                               
other Party under any Loan Document shall come due on a day other than a
Business Day, payment shall instead be considered due on the next succeeding
Business Day and the extension of time shall be reflected in computing interest.

          4.12 Manner and Treatment of Payments.
               -------------------------------- 

          (a)   Each payment hereunder (except payments pursuant to Sections
                                        ------       
     3.7, 3.8, 13.11 and 13.15) or on the Notes or under any other Loan Document
     shall be made, without setoff, counterclaim or deduction of any kind, to
     the Administrative Agent, at the Administrative Agent's Office, for the
     account of each of the Lenders or the Administrative Agent, as the case may
     be, in immediately available funds not later than 11:00 a.m., California
     local time, on the day of payment (which must be a Business Day). All later
     payments shall be deemed received on the next succeeding Business Day. The
     amount of all payments received by the Administrative Agent for the account
     of each Lender shall be paid by the Administrative Agent to the applicable
     Lender in immediately available funds and, if such payment was received by
     the Administrative Agent by 11:00 a.m., California local time, on a
     Business Day and not so made available to the account of a Lender on that
     Business Day, the Administrative Agent shall reimburse that Lender for the
     cost to such Lender of funding the amount of such payment at the Federal
     Funds Rate. All payments shall be made in lawful money of the United States
     of America.

          (b)   Each payment or prepayment on account of any Loan shall be made
     and applied pro rata according to the outstanding Advances made by each
     Lender comprising such Loan.

          (c)   Each Lender shall use its best efforts to keep a record of
     Advances made by it and payments received by it with respect to its Note
     and such record shall be presumptive evidence of the amounts owing.
     Notwithstanding the foregoing sentence, no Lender shall be liable to any
     Party for any failure to keep such a record, and no such failure shall
     affect the amount of the Obligations hereunder.

          4.13 Funding Sources.  Nothing in this Agreement shall be deemed to
               ---------------                                               
obligate any Lender to obtain the funds for any Loan or Advance in any
particular place or manner or to constitute a representation by any Lender that
it has obtained or will obtain the funds for any Loan or Advance in any
particular place or manner.

          4.14 Failure to Charge Not Subsequent Waiver.  Any decision by the
               ---------------------------------------                      
Administrative Agent or any Lender not to require payment of any interest
                                                                         
(including interest at the Default Rate), fee, cost or other amount payable
- ----------                                                                 
under any Loan Document, or to calculate any amount payable by a particular
method, on any occasion shall in no way limit or be deemed a waiver of the
Administrative Agent's or such Lender's right to require full payment of any
interest (including interest at the Default Rate), fee, cost or other amount
          ---------                                                         
payable under any Loan Document, or to calculate an amount payable by another
method, on any other or subsequent occasion.

          4.15 Administrative Agent's Right to Assume Payments Will be Made by
               ---------------------------------------------------------------
Borrower.  Unless the Administrative Agent shall have been notified by Borrower
- --------                                                                       
prior to the date on which any payment to be made by Borrower hereunder is due
that Borrower does not intend to remit such payment, the Administrative Agent
may, in its discretion, assume that Borrower has remitted such payment when so
due and the Administrative Agent may, in its discretion and in reliance upon
such assumption, make available to each Lender on such payment date an amount
equal to such Lender's share of such assumed payment.  If Borrower has not in
fact remitted such payment to the Administrative Agent, each Lender shall
forthwith on demand repay to the Administrative Agent the amount of such assumed
payment made available to such Lender, together with interest thereon in respect
of each day from and including the date such amount was made available by the
Administrative Agent to such Lender to the date such amount is repaid to the
Administrative Agent at the Federal Funds Rate.

          4.16 Authority to Charge Account.  Borrower hereby authorizes the
               ---------------------------                                 
Administrative Agent to charge the Designated Deposit Account or any other
demand deposit account maintained by Borrower with the Administrative Agent, in
such amounts as may from time to time be necessary to cause timely payment of
principal, interest, fees and other charges payable by Borrower under the Loan
Documents, but only to the extent that any such payment is not otherwise made
when due.  Nothing herein shall obligate the Administrative Agent to charge any
such account in this manner or to charge any account at a time when there are
not sufficient good funds in such account.

          4.17 Fee Determination Detail. The Administrative Agent, and any
               ------------------------    
Lender, shall provide reasonable detail to Borrower regarding the manner in
which the amount of any payment to the Lenders, or that Lender, under Article 3
has been determined.

          4.18 Survivability.  All of Borrower's obligations under Sections 3.7
               -------------    
and 3.8 shall survive for one year following the date on which all Loans
hereunder are fully paid; provided, however, that such obligations shall not,
                          --------                                           
from and after the date on which all Loans hereunder are fully paid, be deemed
secured Obligations for any purpose under the Loan Documents.

          4.19 Withholding Gross-Up.  Each payment of any amount payable by
               --------------------                                          
Borrower or any other Party under this Agreement or any other Loan Document
shall be made free and clear of, and without reduction by reason of, any taxes,
assessments or other charges imposed by any Governmental Agency, central bank or
comparable authority, excluding (i) taxes imposed on or measured in whole or in
                      ---------                                                
part by overall net income, gross income or gross receipts, (ii) franchise taxes
imposed on any Lender by (A) any jurisdiction (or political subdivision thereof)
in which it is organized or maintains its principal office or LIBOR Lending
Office or (B) any jurisdiction (or political subdivision thereof) in which it is
"doing business", (iii) any withholding 

                                      -46-
<PAGE>
 
taxes or other taxes based on gross income imposed by the United States of
America that are not attributable to any change in any Law or the interpretation
or administration of any Law by any Governmental Agency and (iv) any withholding
tax or other taxes based on gross income imposed by the United States of America
for any period with respect to which it has failed to provide Borrower with the
appropriate form or forms required by Section 13.23, to the extent such forms
are then available under applicable Laws (all such non-excluded taxes,
assessments or other charges being hereinafter referred to as "Taxes"). To the
extent that Borrower or any other Party is obligated by applicable Laws to make
any deduction or withholding on account of Taxes from any amount payable to any
Lender under this Agreement, they shall (i) make such deduction or withholding
and pay the same to the relevant Governmental Agency and (ii) pay such
additional amount to that Lender as is necessary to result in that Lender's
receiving a net after-Tax amount equal to the amount to which that Lender would
have been entitled under this Agreement absent such deduction or withholding. If
and when receipt of such payment results in an excess payment or credit to that
Lender on account of such Taxes, that Lender shall promptly refund such excess
to Borrower or the relevant Party.

Leasehold Mortgage creates a valid and perfected Lien in the Collateral
described therein securing the Obligations. The Deposit Account Agreements
create a valid and perfected Lien in the Collateral described therein (including
without limitation the Operating Accounts) securing the Obligations. Each of the
Liens described in this Section are of first priority, subject only to Permitted
Encumbrances, Permitted Rights of Others and matters described in Schedule 7.8.

the Tribe has no authority, independent of Borrower, to incur any obligation on
behalf of Borrower, to bind any Authority Property, or to grant Liens upon any

conduct Class II or Class III gaming activities for any reason for more than
five consecutive days to the extent that such failure results in a Material
Adverse Effect (nothing in this clause requiring the conduct of gaming
operations at the Proposed Expansion prior to the opening thereof); or

           (t)   The occurrence of any event or circumstance which results in
the prohibition of the Tribe to conduct Class II or Class III gaming activities
at Mohegan Sun through the Borrower for a period in excess of five consecutive
days (nothing in this clause requiring the conduct of gaming operations at the
Proposed Expansion prior to the opening thereof); or

remedies of the Administrative Agent or the Lenders provided for elsewhere in
this Agreement, or the Loan Documents, or by applicable Law, or in equity, or
otherwise:

           (a)  Upon the occurrence, and during the continuance, of any Event of
Default other than an Event of Default described in Section 11.1(n):

                 (i)    the commitment to make Advances and issue Letters of
     Credit and all other obligations of the Administrative Agent, the Issuing
     Lender and the Lenders and all rights of Borrower and any other Parties
     under the Loan Documents shall be suspended without notice to or demand
     upon the Tribe or Borrower, which are expressly waived by the Tribe and
     Borrower, except that the Requisite Lenders (or, in the case of any Event
               ------      
     of Default which arises under a provision of the Loan Documents the
     amendment of which requires the consent of all the Lenders under Section
     13.2, all of the Lenders) may waive the Event of Default or, without
     waiving, determine, upon terms and conditions satisfactory to such Lenders,
     to reinstate the Commitment and make further Advances and issue further
     Letters of Credit, which waiver or determination shall apply equally to,
     and shall be binding upon, all of the Lenders;

                 (ii)   the Issuing Lender may, with the approval of the
     Administrative Agent on behalf of the Requisite Lenders, demand immediate
     payment by Borrower of an amount equal to the aggregate amount of all

                 (iii)  the Requisite Lenders may request the Administrative
     Agent to, and the Administrative Agent thereupon shall, terminate the
     Commitment and declare all or any part of the unpaid principal of all
     Loans, all interest accrued and unpaid thereon and all other amounts
     payable under the

                                      -85-
<PAGE>
 
          Loan Documents to be forthwith due and payable, whereupon the same
          shall become and be forthwith due and payable, without protest,

          all of which are expressly waived by Borrower.

          11.1(n):

                 (i)    the commitment to make Advances and issue Letters of
     Credit and all other obligations of the Administrative Agent, the Issuing
     Lender and the Lenders and all rights of Borrower and any other Parties
     under the Loan Documents shall terminate without notice to or demand upon
     Borrower, which are expressly waived by Borrower and the Tribe;

                 (ii)   an amount equal to the aggregate amount available for
     drawing under outstanding Letters of Credit shall forthwith become due and
     payable to the Issuing Lender without protest, presentment, notice of

          (c)   Upon the occurrence and during the continuance of any Event of
Default, the Administrative Agent, without notice or demand upon Borrower or the

accordance with applicable Laws (but only with the consent of the Requisite
Lenders) to protect, exercise and enforce their rights and remedies under the
Loan Documents (including the Collateral Documents) against Borrower, the Tribe
and any other Party and such other rights and remedies as are provided by Law or
equity.

          (d)   The order and manner in which the Lenders' rights and remedies
are to be exercised shall be determined by the Requisite Lenders in their sole
discretion, and all payments received after the occurrence of any Default or

shall be applied first to the costs and expenses (including attorneys' fees and
disbursements payable pursuant to Section 13.3) of the Administrative Agent,
acting as Administrative Agent, and of the Lenders, and thereafter paid pro rata
to the Lenders in the same proportions that the aggregate Obligations owed to
each Lender under the Loan Documents bear to the aggregate Obligations owed
under the Loan Documents to all the Lenders, without priority or preference
among the Lenders. Regardless

of how each Lender may treat payments for the purpose of its own accounting, for
the purpose of computing the Obligations hereunder and under the other Loan
Documents, payments shall be applied first, to the costs and expenses of the
                                     -----
Administrative Agent, acting as the Administrative Agent, and the Lenders, as
set forth above, second, to the payment of accrued and unpaid interest due under
                 ------
any Loan Documents to and including the date of such application (ratably, and
without duplication, according to the accrued and unpaid interest due under each
of the Loan Documents), and third, to the payment of all other amounts
                            -----
(including principal and fees) then owing to the Administrative Agent or the
Lenders under the Loan Documents. No application of payments will cure any Event
of Default, or prevent acceleration, or continued acceleration, of amounts
payable under the Loan Documents, or prevent the exercise, or continued
exercise, of rights or remedies of the Lenders hereunder or thereunder or at law
or in equity.

                           THE ADMINISTRATIVE AGENT
                           ------------------------

          13.1  Appointment and Authorization. Each Lender hereby irrevocably
                -----------------------------
appoints and authorizes the Administrative Agent to take such action as agent on
its behalf and to exercise such powers under the Loan Documents as are delegated
to the Administrative Agent by the terms thereof or are reasonably incidental,
as determined by the Administrative Agent, thereto. This appointment and
authorization is intended solely for the purpose of facilitating the servicing
of the Loans and Letters of Credit and does not constitute appointment of the
Administrative Agent as trustee for any Lender or as representative of any
Lender for any other purpose and, except as specifically set forth in the Loan
                                  ------                                      
Documents to the contrary, the Administrative Agent shall take such action and
exercise such powers only in an administrative and ministerial capacity.  The
Administrative Agent is the agent of the Lenders only and does not assume any
agency relationship with the Tribe or Borrower, express or implied.

          13.2  Business Activities with the Tribe and Borrower. Bank of America
                -----------------------------------------------
(and each successor Administrative Agent) has the same rights and powers under
the Loan Documents as any other Lender and may exercise the same as though it
was not the Administrative Agent, and the term "Lender" or "Lenders" includes
Bank of America in its individual capacity. Each Lender (including Bank of
America and each successor Administrative Agent) and its Affiliates may accept
deposits from, lend money to and generally engage in any kind of banking, trust
or other business with the Tribe or Borrower or any of their Affiliates. Bank of
America may engage in these activities in the same manner as the other Lenders
as if it was not the Administrative Agent and without any duty to account
therefor to the Lenders. Bank of America (and each successor Administrative
Agent) need not account to any other Lender for any monies received by it for
reimbursement of its costs and expenses as Administrative Agent hereunder, or
for any monies received by it in its capacity as a Lender hereunder. The
Administrative Agent shall not be deemed to hold a fiduciary, trust or other
special relationship with any Lender and no implied covenants, functions,
responsibilities, duties, obligations or liabilities shall be read into this
Agreement or otherwise exist against the Administrative Agent.

          13.3  Proportionate Interest of the Lenders in any Collateral.  The
                -------------------------------------------------------      
Administrative Agent, on behalf of all the Lenders, shall hold in accordance
with the Loan Documents all items of any collateral or interests therein
received or held by the Administrative Agent.  Subject to the Administrative
Agent's and the Lenders' rights to reimbursement for their costs and expenses
hereunder (including attorneys' fees and disbursements and other professional
           ---------                                                         
services), each Lender shall have an interest in any collateral or interests
therein in the same proportions that the aggregate Obligations owed such Lender
under the Loan Documents (other than an Approved Swap Agreement) bear to the
aggregate Obligations owed under the Loan Documents to all the Lenders, without
priority or preference among the Lenders.  Any obligation owed to a Lender under
an Approved Swap Agreement shall rank pari passu with the Obligations under the
                                      ---- -----                               
Loan Documents up to an amount equal to the Swap Termination Value (as
determined by the

                                      -88-
<PAGE>
 
Administrative Agent) of that Approved Swap Agreement, and shall be subordinate
to the Obligations under other Loan Documents to the extent of any excess over
such amount.

          13.4  Lenders' Credit Decisions. Each Lender agrees that it has,
                -------------------------
independently and without reliance upon the Administrative Agent, any other
Lender or the directors, officers, agents, employees or attorneys of the
Administrative Agent or of any other Lender, and instead in reliance upon
information supplied to it by or on behalf of the Tribe and Borrower and upon
such other information as it has deemed appropriate, made its own independent
credit analysis and decision to enter into this Agreement. Each Lender also
agrees that it shall, independently and without reliance upon the Administrative
Agent, any other Lender or the directors, officers, agents, employees or
attorneys of the Administrative Agent or of any other Lender, continue to make
its own independent credit analyses and decisions in acting or not acting under
the Loan Documents.

          13.5  Action by Administrative Agent.
                ------------------------------ 

                (a) The Administrative Agent may assume that no Default or Event
     of Default has occurred and is continuing, unless the Administrative Agent
     has received notice from the Tribe or Borrower stating the nature of the
     Default or Event of Default or has received notice from a Lender stating
     the nature of the Default or Event of Default and that such Lender
     considers the Default or Event of Default to have occurred and to be
     continuing.

                (b) The Administrative Agent has only those obligations under
     the Loan Documents as are expressly set forth therein.

                (c) Except for any obligation expressly set forth in the Loan
                    ------ 
     Documents and as long as the Administrative Agent may assume that no Event
     of Default has occurred and is continuing, the Administrative Agent may,
     but shall not be required to, exercise its discretion to act or not act,
     except that the Administrative Agent shall be required to act or not act
     ------
     upon the instructions of the Requisite Lenders (or of all the Lenders, to
     the extent required by Section 13.2) and those instructions shall be
     binding upon the Administrative Agent and all the Lenders, provided that
                                                                --------
     the Administrative Agent shall not be required to act or not act if to do
     so would be contrary to any Loan Document or to applicable Law or would
     result, in the reasonable judgment of the Administrative Agent, in
     substantial risk of liability to the Administrative Agent .

                (d) If the Administrative Agent has received a notice specified
     in clause (a), the Administrative Agent shall give notice thereof to the
     Lenders and shall act or not act upon the instructions of the Requisite
     Lenders (or of all the Lenders, to the extent required by Section 13.2),
     provided that the Administrative Agent shall not be required to act or not
     --------  
     act if to do so would be contrary to any Loan Document or to applicable Law
     or would result, in the reasonable judgment of the Administrative Agent, in
     substantial risk of liability to the Administrative Agent, and except that
                                                                    ------
     if the Requisite Lenders (or all the Lenders, if required under Section
     13.2) fail, for five Business Days after the receipt of notice from the

                                      -89-
<PAGE>
 
     Administrative Agent, to instruct the Administrative Agent, then the
     Administrative Agent, in its sole discretion, may act or not act as it
     deems advisable for the protection of the interests of the Lenders, until
     such time as it receives such a notice from the Requisite Lenders.

                (e) The Administrative Agent shall have no liability to any
     Lender for acting as instructed by the Requisite Lenders, or for refraining
     from acting, if so instructed by the Requisite Lenders (or, in each case,
     all the Lenders, if required under Section 13.2), notwithstanding any other
     provision hereof.

          13.6  Liability of Administrative Agent. Neither the Administrative
                --------------------------------- 
Agent nor any of its directors, officers, agents, employees or attorneys shall
be liable for any action taken or not taken by them under or in connection with
the Loan Documents, except for their own gross negligence or willful misconduct.
                    ------
Without limitation on the foregoing, the Administrative Agent and its directors,
officers, agents, employees and attorneys:

                (a) May treat each Lender identified on Schedule 1.1 as the
     owner of its Pro Rata Share until the Administrative Agent receives notice
     of the assignment or transfer thereof, in form satisfactory to the
     Administrative Agent, signed by the payee, and may treat each Lender as the
     owner of that Lender's interest in the Obligations for all purposes of this
     Agreement until the Administrative Agent receives notice of the assignment
     or transfer thereof, in form satisfactory to the Administrative Agent,
     signed by that Lender.

                (b) May consult with legal counsel (including in-house legal
                                                    --------- 
     counsel), accountants (including in-house accountants) and other
                            ---------
     professionals or experts selected by it, or with legal counsel, accountants
     or other professionals or experts for the Tribe, Borrower or the Lenders,
     and shall not be liable for any action taken or not taken by it in good
     faith in accordance with any advice of such legal counsel, accountants or
     other professionals or experts.

                (c) Shall not be responsible to any Lender for any statement,
     warranty or representation made in any of the Loan Documents or in any
     notice, certificate, report, request or other statement (written or oral)
     given or made in connection with any of the Loan Documents.

                (d) Except to the extent expressly set forth in the Loan
                    ------ 
     Documents, shall have no duty to ask or inquire as to the performance or
     observance by the Tribe, Borrower or any other Party of any of the terms,
     conditions or covenants of any of the Loan Documents or to inspect any
     collateral or the Property, books or records of the Tribe or Borrower.

                (e) Will not be responsible to any Lender for the due execution,
     legality, validity, enforceability, genuineness, effectiveness, sufficiency
     or value of any Loan Document, any other instrument or writing furnished
     pursuant thereto or in connection therewith, or any collateral.

                                      -90-
<PAGE>
 
          (f) Will not incur any liability by acting or not acting in reliance
   upon any Loan Document, notice, consent, certificate, statement, request or
   other instrument or writing believed by it to be genuine and signed or sent
   by the proper party or parties.

          (g) Will not incur any liability for any arithmetical error in
   computing any amount paid or payable by the Borrower or any Affiliate thereof
   or paid or payable to or received or receivable from any Lender under any
   Loan Document, including, without limitation, principal, interest, commitment
                  ---------
   fees, Advances and other amounts; provided that, promptly upon discovery of
                                     --------
   such an error in computation, the Administrative Agent, the Lenders and (to
   the extent applicable) Borrower or its Affiliates shall make such adjustments
   as are necessary to correct such error and to restore the parties to the
   position that they would have occupied had the error not occurred.

       13.7  Indemnification.  Each Lender shall, ratably in accordance with 
             ---------------        
its Pro Rata Share, indemnify and hold the Administrative Agent and its
directors, officers, agents, employees and attorneys harmless against any and
all liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, costs, expenses or disbursements of any kind or nature whatsoever
(including reasonable attorneys' fees and disbursements) that may be imposed on,
 ---------
incurred by or asserted against it or them in any way relating to or arising out
of the Loan Documents (other than losses incurred by reason of the failure of
Borrower to pay the indebtedness represented by the Loan Documents) or any
action taken or not taken by it as Administrative Agent thereunder, except such
as result from its own gross negligence or willful misconduct. Without
limitation on the foregoing, each Lender shall reimburse the Administrative
Agent upon demand for that Lender's ratable share of any cost or expense
incurred by the Administrative Agent in connection with the negotiation,
preparation, execution, delivery, amendment, waiver, restructuring,
reorganization (including a bankruptcy reorganization), enforcement or attempted
                ---------
enforcement of the Loan Documents.

       13.8  Successor Administrative Agent.  The Administrative Agent may, 
             ------------------------------      
and at the request of the Requisite Lenders shall, resign as Administrative
Agent (i) upon 30 days' notice to the Borrower and the Lenders or (ii) if the
Administrative Agent determines that for it to continue as Administrative Agent
would result in a conflict of interest affecting the Administrative Agent, or
would create an unacceptable risk of significant liability of the Administrative
Agent to a third party, or would otherwise be inadvisable under prevailing
standards of banking prudence, at any time, and effective immediately upon
written notice to Borrower and the Lenders. If the Administrative Agent so
resigns, (a) the Requisite Lenders shall appoint a successor Administrative
Agent, who must be from among the Lenders (and reasonably acceptable to Borrower
unless an Event of Default exists), provided that any resigning Administrative
                                    --------
Agent shall be entitled to appoint a successor Administrative Agent from among
the Lenders, subject to acceptance of appointment by that successor
Administrative Agent, if the Requisite Lenders have not appointed a successor
Administrative Agent within 30 days after the date the resigning Administrative
Agent gave notice of resignation; (b) upon a successor's acceptance of
appointment

                                      -91-
<PAGE>
 
as Administrative Agent, the successor will thereupon succeed to and become
vested with all the rights, powers, privileges and duties of the resigning
Administrative Agent or the removed Administrative Agent; and (c) upon the
effectiveness of any resignation, the resigning Administrative Agent thereupon
will be discharged from its duties and obligations thereafter arising under the
Loan Documents other than obligations arising as a result of any action or
inaction of the resigning Administrative Agent prior to the effectiveness of
such resignation. Upon any resignation of Bank of America (or any successor
Administrative Agent) as Administrative Agent, Bank of America (or such
successor) shall be deemed to have concurrently resigned as Issuing Lender with
respect to the issuance of any further Letters of Credit hereunder (including
without limitation the extension of the expiration of any outstanding Letter of
Credit), and the successor Administrative Agent shall (i) be deemed concurrently
appointed as Issuing Lender, and (ii) shall promptly issue Letters of Credit to
replace or support any outstanding Letters of Credit issued by Bank of America.

       13.9  Performance of Conditions.  For the purpose of determining 
             -------------------------         
fulfillment by the Tribe and Borrower of conditions precedent specified in
Section 10.1 and Section 10.2 only, each Lender shall be deemed to have
consented to, and approved or accepted, or to be satisfied with each document or
other matter sent by the Administrative Agent to such Lender for consent,
approval, acceptance or satisfaction, or required under Article 10 to be
consented to, or approved by or acceptable or satisfactory to, that Lender,
unless an officer of the Administrative Agent who is responsible for the
transactions contemplated by the Loan Documents shall have received written
notice from that Lender prior to the making of the requested Loan or the
issuance of the requested Letter of Credit specifying its objection thereto and
either (i) such objection shall not have been withdrawn by written notice to the
Administrative Agent or (ii) in the case of any condition to the making of a
Loan, that Lender shall not have made available to the Administrative Agent that
Lender's Pro Rata Share of such Loan.

       13.10 Collateral Matters.
             ------------------ 

             (a) The Administrative Agent is authorized by each Lender, without
    the necessity of any notice to or further consent from any Lender, and
    without the obligation to take any such action, to take any action with
    respect to any Collateral or any Collateral Document which may from time to
    time be necessary to perfect and maintain perfected the Liens of the
    Collateral Documents.

             (b) The Lenders irrevocably authorize the Administrative Agent, at
    its option and in its discretion, to release any Lien granted to or held by
    the Administrative Agent upon any Collateral (i) upon termination of the
    Commitment and the payment in full of all Loans and all other Obligations
    payable under this Agreement (other than the obligations referenced in
    Section 3.18) and under the other Loan Documents; (ii) constituting Property
    of Borrower or its Affiliates which is sold, transferred or otherwise
    disposed of in connection with any transaction not prohibited by this
    Agreement or the Loan Documents; (iii) constituting Property leased to
    Borrower under an operating lease which has expired or been 

                                      -92-
<PAGE>
 
    terminated in a transaction not prohibited by this Agreement or which will
    concurrently expire and which has not been and is not intended by the
    Borrower to be, renewed or extended; (iv) consisting of an instrument, if
    the Indebtedness evidenced thereby has been paid in full; or (v) if approved
    or consented to by those of the Lenders required by Section 13.2. Upon
    request by the Administrative Agent, the Lenders will confirm in writing the
    Administrative Agent's authority to release particular types or items of
    Collateral pursuant to this Section.

       13.11  No Obligations of Borrower or the Tribe.  Nothing contained in 
              ---------------------------------------         
this Article 12 shall be deemed to impose upon Borrower or the Tribe any
obligation in respect of the due and punctual performance by the Administrative
Agent of its obligations to the Lenders under any provision of this Agreement,
and the Tribe and Borrower shall have no liability to the Administrative Agent
or any of the Lenders in respect of any failure by the Administrative Agent or
any Lender to perform any of its obligations to the Administrative Agent or the
Lenders under this Agreement.

any right, power, privilege or remedy may be, or may be deemed to be, a waiver
thereof; nor may any single or partial exercise of any right, power, privilege
or remedy preclude any other or further exercise of the same or any other right,
power, privilege or remedy.  The terms and conditions of Article 10 hereof are
inserted for the sole benefit of the Creditors and may be waived in whole or in
part, with or without terms or conditions, in respect of any Loan or Letter of
Credit without prejudicing the Creditors' right to assert them in whole or in
part in respect of any other Loan or Letter of Credit.

       14.2  Amendments; Consents.  No amendment, modification, supplement, 
             --------------------

Loan Document, no approval or consent thereunder, and no consent to any
departure by Borrower or any other Party therefrom, may in any event be
effective unless in writing signed by the Administrative Agent with the approval
in writing of the Requisite Lenders, and then only in the specific instance and
for the specific purpose given; and, without the approval in writing of all the
Lenders, no amendment, modification, supplement, termination, waiver or consent
may be effective:

             (a) To (i) amend or modify the principal of, or the amount of

    Maturity Date or any Reduction Date, or to release any Collateral (except as
    specifically provided for in any Loan Document);

             (d) To amend or modify any provision of this Agreement in a manner
    which materially and adversely affects the Administrative Agent or the
    Issuing Lender without their written consent;

                                      -94-
<PAGE>
 
             (e) To amend or modify any provision of this Agreement that
    expressly requires the consent or approval of all the Lenders.

Any amendment, modification, supplement, termination, waiver or consent pursuant
to this Section 13.2 shall apply equally to, and shall be binding upon, all of
the Creditors.

       14.3  Costs, Expenses and Taxes.  Borrower shall pay on demand the 
             -------------------------        
reasonable costs and expenses of (a) the Administrative Agent and the Lead
Arranger in connection with the negotiation, preparation, syndication, closing,
execution and delivery of the Loan Documents, including without limitation, the
reasonable attorneys' fees and disbursements of Sheppard, Mullin, Richter &
Hampton LLP and Dorsey & Whitney, LLP and the allocated cost of any internal
counsel to the Administrative Agent, (b) the Construction Consultant in

the Creditors in connection with each refinancing, restructuring, reorganization
(including a bankruptcy reorganization) and enforcement or attempted enforcement
 ---------
of the Loan Documents, and any matter related thereto, in each case including,
                                                                    ---------
filing fees, recording fees, title insurance fees, appraisal fees, search fees
and other out-of-pocket expenses and the reasonable fees and out-of-pocket
expenses of any legal counsel (including the allocated fees and all
disbursements and other expenses of any internal legal counsel), independent
public accountants and other outside experts retained by the Administrative
Agent or any Lender, and including, without limitation, any costs, expenses or
fees incurred or suffered by the Creditors in connection with or during the
course of any bankruptcy or insolvency proceedings of Borrower. Borrower shall
pay any and all documentary and other taxes (other than income or gross receipts
taxes generally applicable to banks) and all costs, expenses, fees and charges
payable or determined to be payable in connection with the filing or recording
of this Agreement, any other Loan Document or any other instrument or writing to
be delivered hereunder or thereunder, or in connection with any transaction
pursuant hereto or thereto, and shall reimburse, hold harmless and indemnify the
Administrative Agent and the Lenders from and against any and all loss,
liability or legal or other expense with respect to or resulting from any delay
in paying or failure to pay any such tax, cost, expense, fee or charge or that
any of them may suffer or incur by reason of the failure of any Party to perform
any of its Obligations. Any amount payable to the Administrative Agent or any
Lender under this Section shall bear interest at the Default Rate.

       14.4  Nature of the Lenders' Obligations.  The obligations of the Lenders
             ----------------------------------    
hereunder are several and not joint or joint and several. Nothing contained in
this Agreement or any other Loan Document and no action taken by the
Administrative Agent or the Lenders or any of them pursuant hereto or thereto
may, or may be deemed to, make the Lenders a partnership, an association, a
joint venture or other entity, either among themselves or with the Borrower or
any Affiliate of the Borrower. Each Lender's obligation to make any Advance
pursuant hereto is several and not joint or joint and several. A default by any
Lender will not increase the percentage of the Commitment attributable to any
other Lender.  Any Lender not in default may, if it desires, 

                                      -95-
<PAGE>
 
assume in such proportion as the nondefaulting Lenders agree the obligations of
any Lender in default, but is not obligated to do so.

       14.5  Survival of Representations and Warranties.  All representations 
             ------------------------------------------  
and warranties contained herein or in any other Loan Document, or in any
certificate or other writing delivered by or on behalf of any one or more of the
Parties to any Loan Document, will survive the making of the Loans and the
issuance of Letters of Credit hereunder and the execution and delivery of the
Loan Documents, and have been or will be relied upon by the Administrative Agent
and each Lender, notwithstanding any investigation made by the Administrative
Agent or any Lender or on their behalf.

       14.6  Notices.  Except as otherwise expressly provided in the Loan 
             -------       
Documents (a) all notices, requests, demands, directions and other
communications provided for hereunder or under any other Loan Document must be
in writing and must be mailed, telegraphed, telecopied, delivered or sent by
recognized overnight courier service, to the appropriate party at the address
set forth on the signature pages of this Agreement or other applicable Loan
Document or, as to any party to any Loan Document, at any other address as may
be designated by it in a written notice sent to all other parties to such Loan
Document in accordance with this Section; and (b) any notice, request, demand,
direction or other communication given by telecopier, must be confirmed within
48 hours by letter mailed or delivered to the appropriate party at its
respective address. Except as otherwise expressly provided in any Loan Document,
if any notice, request, demand, direction or other communication required or
permitted by any Loan Document is given by mail it will be effective on the
earlier of receipt or the third Business Day after deposit in the United States
mail with first class or airmail postage prepaid; if given by telegraph or
cable, when delivered to the telegraph company with charges prepaid; if given by
telex or telecopier, when sent; or if given by personal delivery, when
delivered. Notices given by the Borrower under Articles 2 and 3 shall be deemed
given on actual receipt by the Administrative Agent.

       14.7  Execution of Loan Documents.  Unless the Administrative Agent 
             ---------------------------     
otherwise specifies with respect to any Loan Document, this Agreement and any
other Loan Document may be executed in any number of counterparts and any party
hereto or thereto may execute any counterpart, each of which when executed and
delivered will be deemed to be an original and all of which counterparts of this
Agreement or any other Loan Document, as the case may be, when taken together
will be deemed to be but one and the same instrument. The execution of this
Agreement or any other Loan Document by any party hereto or thereto will not
become effective until counterparts hereof or thereof, as the case may be, have
been executed by all the parties hereto or thereto.

       14.8  Binding Effect; Assignment.
             -------------------------- 

             (a) This Agreement and the other Loan Documents shall be binding
    upon and shall inure to the benefit of the parties hereto and thereto and
    their respective successors and assigns, except that Borrower and its
    Affiliates may not assign their rights hereunder or  

                                      -96-
<PAGE>
 
    thereunder or any interest herein or therein without the prior written
    consent of all the Lenders. Any assignment by the Borrower or its Affiliates
    without the prior written consent of the Lenders shall be void, provided
    that no Person other than the Lenders shall have any rights under this
    sentence. Each Lender represents that it is not acquiring any Note with a
    view to the distribution thereof within the meaning of the Securities Act of
    1933, as amended (subject to any requirement that disposition of such Notes
    must be within the control of such Lender). Any Lender may at any time
    pledge its Note, if any, or any other instrument evidencing its rights as a
    Lender under this Agreement to a Federal Reserve Bank, but no such pledge
    shall release that Lender from its obligations hereunder or grant to such
    Federal Reserve Bank the rights of a Lender hereunder absent foreclosure of
    such pledge.

             (b) From time to time following the Closing Date, each Lender may
    assign to one or more Eligible Assignees all or any portion of its Pro Rata
    Share; provided that (i) such Eligible Assignee, if not then a Lender or an
    Affiliate of the assigning Lender, shall be approved by each of the
    Administrative Agent and Borrower (neither of which approvals shall be
    unreasonably withheld or delayed), (ii) such assignment shall be evidenced
    by an Assignment Agreement, a copy of which shall be furnished to the
    Administrative Agent, (iii) except in the case of an assignment to an
    Affiliate of the assigning Lender or to another Lender of the entire
    remaining Commitment of the assigning Lender, the assignment shall be of a
    Pro Rata Share of not less than $10,000,000, and (iv) the effective date of
    any such assignment shall be as specified in the Assignment Agreement, but
    not earlier than the date which is five Business Days after the date the
    Administrative Agent has received the Assignment Agreement unless the
    Administrative Agent otherwise agrees. Upon the effective date of such
    Assignment Agreement, the Eligible Assignee named therein shall be a Lender
    for all purposes of this Agreement, with the Pro Rata Share set forth
    therein and, to the extent of such Pro Rata Share, the assigning Lender
    shall be released from its further obligations under this Agreement.
    Borrower agrees that it shall execute and deliver (against delivery by the
    assigning Lender to Borrower of any Note in its possession) to such assignee
    Lender, a Note evidencing that assignee Lender's Pro Rata Share, and to the
    assigning Lender, a Note evidencing the remaining balance Pro Rata Share
    retained by the assigning Lender (in each case, if Notes are requested by
    such Assignee under Section 2.1).

             (c) By executing and delivering an Assignment Agreement, the
    Eligible Assignee thereunder acknowledges and agrees that: (i) other than
    the representation and warranty that it is the legal and beneficial owner of
    the Pro Rata Share being assigned thereby free and clear of any adverse
    claim, the assigning Lender has made no representation or warranty and
    assumes no responsibility with respect to any statements, warranties or
    representations made in or in connection with this Agreement or the
    execution, legality, validity, enforceability, genuineness or sufficiency of
    this Agreement or any other Loan Document; (ii) the assigning Lender has
    made no representation or warranty and assumes no responsibility with
    respect to the financial condition of Borrower or the performance by
    Borrower of the Obligations; (iii) it has received a copy of this Agreement,
    together with copies of the most recent financial statements delivered
    pursuant to Section 8.1 and such other 

                                      -97-
<PAGE>
 
    documents and information as it has deemed appropriate to make its own
    credit analysis and decision to enter into such Assignment Agreement; (iv)
    it will, independently and without reliance upon the Administrative Agent or
    any Lender and based on such documents and information as it shall deem
    appropriate at the time, continue to make its own credit decisions in taking
    or not taking action under this Agreement; (v) it appoints and authorizes
    the Administrative Agent to take such action and to exercise such powers
    under this Agreement as are delegated to the Administrative Agent by this
    Agreement; and (vi) it will perform in accordance with their terms all of
    the obligations which by the terms of this Agreement are required to be
    performed by it as a Lender.

             (d) The Administrative Agent shall maintain at the Administrative
    Agent's Office a copy of each Assignment Agreement delivered to it. After
    receipt of a completed Assignment Agreement executed by any Lender and an
    Eligible Assignee, and receipt of an assignment fee of $3,500 from such
    Eligible Assignee, Administrative Agent shall, promptly following the
    effective date thereof, provide notice thereof to Borrower and the Lenders.

             (e) Each Lender may grant participations from time to time in a
    portion of its Pro Rata Share to one or more banks or other financial
    institutions (including another Lender); provided, however, that (i) such
    Lender's obligations under this Agreement shall remain unchanged, (ii) such
    Lender shall remain solely responsible to the other parties hereto for the
    performance of such obligations, (iii) the participating banks or other
    financial institutions shall not be a Lender hereunder for any purpose
    except, if the participation agreement so provides, for the purposes of
    Sections 3.7, 3.8, 13.11 and 13.15, (iv) Borrower and the other Creditors
    shall continue to deal solely and directly with such Lender in connection
    with such Lender's rights and obligations under this Agreement, (v) the
    participation interest shall be expressed as a percentage of the granting
    Lender's Pro Rata Share as it then exists and shall not restrict an increase
    in the Commitment, or in the granting Lender's Pro Rata Share, so long as
    the amount of the participation interest is not affected thereby, and (vi)
    the consent of the holder of such participation interest shall not be
    required for amendments or waivers of provisions of the Loan Documents other
                                                                           -----
    than those which (A) extend the Maturity Date, any Reduction Date or any
    ----
    date upon which any payment of money is due to the Lenders, (B) reduce the
    rate of interest on the Loans, any fee or any other monetary amount payable
    to the Lenders, (C) reduce the amount of any installment of principal due
    with respect to the Loans, or (D) release any material portion of the
    Collateral.

             (f) Any Lender (a "Granting Lender") may grant to a special purpose
    funding vehicle (an "SPC") of such Granting Lender, identified as such in
    writing from time to time by the Granting Lender to the Administrative Agent
    and the Borrower, the option to provide all or any part of any Advance that
    such Granting Lender would otherwise be obligated to make pursuant to
    Article 2, provided that (i) nothing herein shall constitute a commitment to
    make any Advance by any SPC, (ii) if an SPC elects not to exercise such
    option or otherwise fails to provide all or any part of such Advance, the
    Granting Lender shall be obligated to make such Advance pursuant to the
    terms hereof, and (iii) the rights of any such SPC shall be derivative of
    the rights of the Granting Lender. Each SPC shall be

                                      -98-
<PAGE>
 
    conclusively presumed to have made arrangements with its Granting Lender for
    the exercise of voting and other rights hereunder in a manner which is
    acceptable to the SPC, and the Administrative Agent, the other Creditors and
    each other Party shall be entitled to rely upon and deal solely with the
    Granting Lender with respect to Advances made by or through its SPC. The
    making of an Advance by an SPC hereunder shall utilize the Pro Rata Share of
    the Commitment of the Granting Lender to the same extent, and as if, such
    Advance were made by the Granting Lender. Each party hereto hereby agrees
    that no SPC shall be liable for any indemnity or similar payment obligation
    under this Agreement (all liability for which shall remain with the related
    Granting Lender). In furtherance of the foregoing, each party hereto hereby
    agrees (which agreement shall survive the termination of this Agreement)
    that, prior to the date that is one year and one day after the payment in
    full of all outstanding senior indebtedness of any SPC, it will not
    institute against, or join any other person in instituting against, such SPC
    any bankruptcy, reorganization, arrangement, insolvency or liquidation
    proceedings or similar proceedings under the laws of the United States or
    any State thereof, provided that the Granting Lender for each SPC hereby
                       -------- ----
    agrees to indemnify, save, and hold harmless each other party hereto for any
    loss, cost, damage and expense arising out of their inability to institute
    any such proceeding against its SPC. In addition, notwithstanding anything
    to the contrary contained in this Section, any SPC may (i) with notice to,
    but without the prior written consent of, the Borrower or the Administrative
    Agent and without paying any processing fee therefor, assign all or a
    portion of its interests in any Advance to its Granting Lender or to any
    financial institutions providing liquidity and/or credit facilities to or
    for the account of such SPC to fund the Advances made by such SPC or to
    support the securities (if any) issued by such SPC to fund such Loans (but
    nothing contained herein shall be construed in derogation of the obligation
    of the Granting Lender to make Advances hereunder), provided that neither
                                                        -------- ----
    the consent of the SPC or of any such assignee shall be required for
    amendments or waivers of provisions of the Loan Documents except for those
    amendments or waivers for which the consent of participants is required
    under Section 13.8(e)(vi), and (ii) disclose on a confidential basis any 
    non-public information relating to its Loans to any rating agency,
    commercial paper dealer or provider of a surety, guarantee or credit or
    liquidity enhancement to such SPC.

       14.9  Lien on Deposits and Property in Possession of any Lender.  As
             ---------------------------------------------------------
security for the prompt payment and performance of all Obligations, Borrower
hereby grants to each Creditor, as the representative of all other Creditors, a
security interest in and a right of off-set with respect to, all its right,
title, and interest in and to any and all deposit accounts now or hereafter
maintained with that Creditor in and to any and all of its Property and the
proceeds thereof now or hereafter in the possession of that Creditor. If an
Event of Default has occurred and is continuing, any Lender (but only with the
consent of the Requisite Lenders) may, to the extent permitted by applicable
Laws, exercise its rights under Article 9 of the Uniform Commercial Code and
other applicable Laws (including its right of off-set) and apply any funds in
any deposit account maintained with it by Borrower and any Property of Borrower
in its possession against the Obligations.

                                      -99-
<PAGE>
 
       14.10  Sharing of Setoffs.  Each Lender severally agrees that if it, 
              ------------------          
through the exercise of any right of setoff, banker's lien or counterclaim
against a Party, or otherwise, receives payment of the Obligations held by it
that is ratably more than any other Lender, through any means, receives in
payment of the Obligations held by that Lender, then: (a) The Lender exercising
the right of setoff, banker's lien or counterclaim or otherwise receiving such
payment shall notify the Administrative Agent and thereafter shall purchase, and
shall be deemed to have simultaneously purchased, from the other Lender a
participation in the Obligations held by the other Lender and shall pay to the
other Lender a purchase price in an amount so that the share of the Obligations
held by each Lender after the exercise of the right of setoff, banker's lien or
counterclaim or receipt of payment shall be in the same proportion that existed
prior to the exercise of the right of setoff, banker's lien or counterclaim or
receipt of payment; and (b) such other adjustments and purchases of
participations shall be made from time to time as shall be equitable to ensure
that all of the Lenders share any payment obtained in respect of the Obligations
ratably in accordance with each Lender's share of the Obligations immediately
prior to, and without taking into account, the payment; provided that, if all or
                                                        --------
any portion of a disproportionate payment obtained as a result of the exercise
of the right of setoff, banker's lien, counterclaim or otherwise is thereafter
recovered from the purchasing Lender by Borrower or any Person claiming through
or succeeding to the rights of Borrower, the purchase of a participation shall
be rescinded and the purchase price thereof shall be restored to the extent of
the recovery. Each Lender that purchases a participation in the Obligations
pursuant to this Section shall from and after the purchase have the right to
give all notices, requests, demands, directions and other communications under
this Agreement with respect to the portion of the Obligations purchased to the
same extent as though the purchasing Lender were the original owner of the
Obligations purchased. Each Party expressly consents to the foregoing
arrangements and agrees that any Lender holding a participation in an Obligation
so purchased may exercise any and all rights of setoff, banker's lien or
counterclaim with respect to the participation as fully as if the Lender were
the original owner of the Obligation purchased; provided, however, that each
                                                --------
Lender agrees that it shall not exercise any right of setoff, banker's lien or
counterclaim with respect to the Obligations without first obtaining the consent
of the Requisite Lenders.

       14.11  Indemnity by Borrower.  Borrower agrees to indemnify, save and 
              ---------------------        
hold harmless each Creditor and their respective Affiliates, directors,
officers, agents, attorneys and employees (collectively the "Indemnitees") from
                                                             -----------
and against: (a) any and all claims, demands, actions or causes of action that
are asserted against any Indemnitee by any third party, if the claim, demand,
action or cause of action directly or indirectly relates to a claim, demand,
action or cause of action that such Person asserts or may assert against
Borrower (or, to the extent related to the Loan Documents or the transactions
contemplated thereby, any Affiliate of Borrower or any officer of Borrower); (b)
any and all claims, demands, actions or causes of action by a third party if the
claim, demand, action or cause of action arises out of or relates to the
Commitment, the use or contemplated use of proceeds of any Loan or Letter of
Credit, the relationship of Borrower and the Lenders under this Agreement or any
transaction contemplated by the Loan Documents; (c) any administrative or
investigative proceeding by any Governmental Agency arising out of or related to
a claim, demand, action or cause of action described in clauses (a) or (b)
above; and (d) any and

                                     -100-
<PAGE>
 
all liabilities, losses, costs or expenses (including reasonable attorneys' fees
                                            ---------
and disbursements and other professional services) that any Indemnitee suffers
or incurs as a result of the assertion of any foregoing claim, demand, action or
cause of action; provided that no Indemnitee shall be entitled to
                 --------
indemnification for any loss caused by its own gross negligence or willful
misconduct. If any claim, demand, action or cause of action is asserted against
any Indemnitee, such Indemnitee shall promptly notify Borrower, but the failure
to so promptly notify Borrower shall not affect Borrower's obligations under
this Section unless Borrower is materially prejudiced thereby (and then only to
the extent prejudiced). Each Indemnitee may contest the validity, applicability
and amount of such claim, demand, action or cause of action with counsel
selected by such Indemnitee. Each Indemnitee is authorized to employ counsel in
enforcing its rights hereunder and in defending any claim, demand, action or
cause of action covered by this Section; provided that each Indemnitee shall
endeavor in connection with any matter covered by this Section which also
involves other Indemnitees, to use reasonable efforts to avoid unnecessary
duplication of effort by counsel for all Indemnitees. Any obligation or
liability of Borrower to any Indemnitee under this Section shall survive the
expiration or termination of this Agreement and the repayment of all Loans and
the payment and performance of all other Obligations (other than the Obligations
referenced in Section 3.18) owed to the Lenders; provided, however, that such
                                                 --------
obligations or liabilities shall not, from and after the date on which the
Obligations are fully paid and the Commitment terminated, be deemed Obligations
for any purpose under the Loan Documents.

       14.12 Nonliability of the Lenders.  Each of the Tribe and Borrower 
             ---------------------------                                
acknowledges and agrees that:

             (a) Any inspections of any Property of Borrower made by or through
    the Creditors are for purposes of administration of the Loan Documents only
    and neither the Tribe nor Borrower is entitled to rely upon the same;

             (b) By accepting or approving anything required to be observed,
    performed, fulfilled or given to the Creditors pursuant to the Loan
    Documents, none of the Creditors shall be deemed to have warranted or
    represented the sufficiency, legality, effectiveness or legal effect of the
    same, or of any term, provision or condition thereof, and such acceptance or
    approval thereof shall not constitute a warranty or representation to anyone
    with respect thereto by any Creditor;

             (c) The relationship between the Borrower and the Creditors is, and
    shall at all times remain, solely that of a borrowers and lenders; no
    Creditor shall under any circumstance be deemed to be in a relationship of
    confidence or trust or a fiduciary relationship with the Tribe or with
    Borrower or their Affiliates, or to owe any fiduciary duty to the Tribe,
    Borrower, or their Affiliates; no Creditor undertakes or assumes any

       14.20  Independent Covenants.  Each covenant in Articles 6, 7, 8 and 9 is
              ---------------------

              (a) Mandatory Arbitration.  At the option of the Administrative

    Agent (exercised in accordance with consent of the Requisite Lenders),
    Borrower or (to the extent it is a party to any such controversy or claim),
    the Tribe, any controversy or claim between or among the parties arising out
    of or relating to this Agreement or any agreements or instruments relating
    hereto or delivered in connection herewith and any claim based on or arising
    from an alleged tort, shall be determined by arbitration. The arbitration
    shall be conducted in accordance with the United States Arbitration Act
    (Title 9, U.S. Code), notwithstanding any choice of law provision in this
    Agreement, and under the Commercial Rules of the American Arbitration
    Association ("AAA"). The arbitrators shall give effect to statutes of
    limitation in determining any claim. Any controversy concerning whether an
    issue is arbitrable shall be determined by the arbitrators. Judgment upon
    the arbitration award may be entered in any court having jurisdiction. The
    institution and maintenance of an action for judicial relief or pursuit of a
    provisional or ancillary remedy shall not constitute a waiver of the right
    of any party, including the plaintiff, to submit the controversy or claim to
    arbitration if any other party contests such action for judicial relief.

             (b) Provisional Remedies, Self-Help and Foreclosure.  No provision
                 -----------------------------------------------   
    of this section shall limit the right of any party to this Agreement to
    exercise self-help remedies such as setoff, to foreclose against or sell any
    real or personal property collateral or security or to obtain provisional or
    ancillary remedies from a court of competent jurisdiction before, after, or
    during the pendency of any arbitration or other proceeding. The exercise of
    a remedy does not waive the right of either party to resort to arbitration
    or reference. At the Requisite Lenders' option, foreclosure under a deed of
    trust or mortgage may be accomplished either by exercise of power of sale
    under the deed of trust or mortgage or by judicial foreclosure.

             (c) Limitation.  This Section shall not be construed to require
                 ----------

          (d)  Assignor and Assignee represent to one another and to the
Administrative Agent that they have duly authorized, executed and delivered this
Assignment, that they are legally entitled to enter into the assignment and
assumption transactions contemplated herein and that, in the case of Assignor,
that it is the legal and beneficial owner of the Assigned Pro Rata Share, free
of any Liens or adverse claims.

          (e)  Assignor shall not be responsible to Assignee for the execution,
effectiveness, accuracy, completeness, legal effect, genuineness, validity,
enforceability, collectibility or sufficiency of any of the Loan Documents
(other than its own due execution of the Loan Documents) or for any
representations, warranties, recitals or statements made therein or in any
written or oral statement or in any financial or other statements, instruments,
reports, certificates or any other documents made or furnished or made available
by Assignor to Assignee (other than written representations, warranties,
recitals or statements made by Assignor therein) or by or on behalf of the
Borrower or the Tribe to Assignor or Assignee in connection with the Loan
Documents and the transactions contemplated thereby or for the financial
condition or business affairs of the Borrower or any other Person liable for the
payment of any Advance or payment of amounts owed in connection with other
extensions of credit under the Loan Agreement or any other matter.  Assignor
shall not be required to ascertain or inquire as to the performance or
observance of any of the terms, conditions, provisions, covenants or agreements
contained in any of the Loan Documents or as to the use of the proceeds of the
Advances or other extensions of credit under the Loan Agreement or as to the
existence or possible existence of any Default or Event of Default.

          (f)  Each party to this Assignment represents and warrants to the
other party to this Assignment that it has full power and authority to enter
into this Assignment and to perform its obligations under this Assignment in
accordance with the provisions of this Assignment, that this Assignment has been
duly authorized, executed and delivered by such party and that this Assignment
constitutes a legal, valid and binding obligation of such party, enforceable in
accordance with its terms, except as enforceability may be limited by applicable

in electronic or other intangible form) of Advances made by it and payments of
principal received by it with respect to this Note, and such record shall be
presumptive evidence of the amounts owing under this Note.

          The undersigned hereby promises to pay all costs and expenses of any
rightful Holder hereof incurred in collecting the undersigned's obligations
hereunder or in enforcing or attempting to enforce any of such Holder's rights

Agent, after making copies of such records as the retiring Defeasance Agent
deems advisable and after deduction and payment to the retiring Defeasance Agent
of all fees and expenses (including court costs and attorneys' fees) payable to,
incurred by, or expected to be incurred by the retiring Defeasance Agent in
connection with the performance of its duties and the exercise of its rights
hereunder.

               -----------------------------

respect to the Defeasance Funds except for Defeasance Agent's willful misconduct
or gross negligence. Defeasance Agent's sole responsibility shall be for the
safekeeping, investment, and disbursement of the Defeasance Funds in accordance
with the terms of this Agreement. Defeasance Agent shall have no implied duties
or obligations and shall not be charged with knowledge or notice of any fact or
circumstance not specifically set forth herein. Defeasance Agent may rely upon
any instrument, not only as to its due execution, validity and effectiveness,
but also as to the truth and accuracy of any information contained therein,
which Defeasance Agent shall in good faith believe to be genuine, to have been
signed or presented by the person or parties purporting to sign the same and to
conform to the provisions of this Agreement. In no event shall Defeasance Agent
be liable for incidental, indirect, special, consequential or punitive damages.
Defeasance Agent shall not be obligated to take any legal action or commence any
proceeding in connection with the Defeasance Funds, any account in which
Defeasance Funds are deposited, this Agreement or the Note Purchase Agreement,
or to appear in, prosecute or defend any such legal action or proceeding.
Defeasance Agent may consult legal counsel selected by it in the event of any
dispute or question as to the construction of any of the provisions hereof or of
any other agreement or of its duties hereunder, or relating to any dispute
involving any party hereto, and shall incur no liability and shall be fully
indemnified from any liability whatsoever in acting in accordance with the
opinion or instruction of such counsel. Issuer and Note Holders, jointly and
severally, shall promptly pay, upon demand, the reasonable fees and expenses of
any such counsel.

          (b) The Defeasance Agent is authorized, in its sole discretion, to
comply with orders issued or process entered by any court with respect to the
Defeasance Funds, without determination by the Defeasance Agent of such court's
jurisdiction in the matter.  If any portion of the Defeasance Funds is at any
time attached, garnished or levied upon under any court order, or in case the
payment, assignment, transfer, conveyance or delivery of any such property shall
be stayed or enjoined by any court order, or in case any order, judgment or
decree shall be made or entered by any court affecting such property or any part
thereof, then and in any such event, the Defeasance Agent is authorized, in its
sole discretion, to rely upon and comply with any such order, writ, judgment or
decree which it is advised by legal counsel selected by it is binding upon it
without the need for appeal or other action; and if the Defeasance Agent
complies with any 

                                      -5-
<PAGE>
 
such order, writ, judgment or decree, it shall not be liable to any of the
parties hereto or to any other person or entity by reason of such compliance
even though such order, writ, judgment or decree may be subsequently reversed,
modified, annulled, set aside or vacated.

          9.  Indemnification of Defeasance Agent.  From and at all times after
              -----------------------------------                              
the date of this Agreement, Issuer, shall, to the fullest extent permitted by
law and to the extent provided herein, indemnify and hold harmless Defeasance
Agent and each director, officer, employee, attorney, agent and affiliate of
Defeasance Agent (collectively, the "Indemnified Parties") against any and all
actions, claims (whether or not valid), losses, damages, liabilities, costs and
expenses of any kind or nature whatsoever (including without limitation
reasonable attorneys' fees, costs and expenses) incurred by or asserted against
any of the Indemnified Parties from and after the date hereof, whether direct,
indirect or consequential, as a result of or arising from or in any way to any
demand, suit, action or proceeding (including any inquiry or investigation) by
any person, including without limitation Issuer or Note Holders, whether
threatened or initiated, asserting a claim for any legal or equitable against
any person under any statute or regulation, including, but not limited to, any
federal or state securities laws, or under any common law or equitable cause or
otherwise, arising from or in connection with the negotiation, preparation,
execution, performance or failure of performance of this Agreement or any
transactions contemplated herein, whether or not any such Indemnified Party is a
party to any such action, proceeding, suit or the target of any such inquiry or
investigation; provided, however, that no Indemnified Party shall have the right
to be indemnified hereunder for any liability finally determined by a court of
competent jurisdiction, subject to no further appeal, to have resulted solely
from the gross negligence or willful misconduct of such Indemnified Party.  If
any such action or claim shall be brought or asserted against any Indemnified
Party, such Indemnified Party shall promptly notify Issuer and Note Holders in
writing, and Issuer and Note Holders shall assume the defense thereof, including
the employment of counsel and the payment of all expenses.  Such Indemnified
Party shall, in its sole discretion, have the right to employ separate counsel
(who may be selected by such Indemnified Party in its sole discretion) in any
such action and to participate in the defense thereof, and the fees and expenses
of such counsel shall be paid by such Indemnified Party, except that Issuer
shall be required to pay such fees and expenses if (a) Issuer agrees to pay such
fees and expenses, or (b) Issuer shall fail to assume the defense of such action
or proceeding or shall fail, in the sole discretion of such Indemnified Party,
to employ counsel satisfactory to the Indemnified Party in any such action or
proceeding, (c) Issuer or Note Holders is the plaintiff in any such action or
proceeding or (d) the named parties to any such action or proceeding (including
any potential parties) include both Indemnified Party and Issuer, and
Indemnified Party shall have been advised by counsel that there may be one or
more legal defenses available to it which are different from or additional to
those available to Issuer.  Issuer shall be jointly and severally liable to pay
fees and expenses of counsel pursuant to the preceding sentence, except that any
obligation to pay under clause (a) shall apply only to the party so agreeing.
All such fees and expenses payable by Issuer pursuant to the foregoing sentence
shall be paid from time to time as incurred, both in advance of and after the
final disposition of such action or claim. All of the foregoing losses, damages,
costs and expenses of the Indemnified Parties shall be payable by Issuer upon
demand by such Indemnified Party.  The obligations of Issuer under this Section
                                                                        -------

               (ii) This Agreement has been duly and validly authorized,
               executed and delivered by the Issuer, and constitutes a valid and
               binding agreement of Issuer, enforceable in accordance with its
               terms.

               (iii)  The execution, delivery, and performance by Issuer of this
               Agreement is in accordance with the Note Purchase Agreement and
               will not violate, conflict with, or cause a default under the
               governing instruments of Issuer, any applicable law or
               regulation, any court order or administrative ruling or decree to
               which Issuer is a party or any of its property is subject, or any
               agreement, contract, indenture, or other binding arrangement,
               including without limitation the Note Purchase Agreement, to
               which Issuer is a party or any of its property is subject.

               (iv) Roland Harris and each of the other officers of the

Escrow Agent, and to the other parties, to cause Escrow Agent to be relieved of
its duties hereunder and to select a substitute escrow agent to serve hereunder.
The Escrow Agent may resign at any time upon 30 days written notice to all
parties hereto.  Such resignation shall take effect upon receipt by the Escrow
Agent of an instrument of acceptance executed by a successor escrow agent and

perform hereunder, except that the Escrow Agent shall transfer to the substitute
escrow agent upon request therefor all funds and Cash Equivalents maintained by
the Escrow Agent hereunder and originals of all books, records, plans and other
documents in the Escrow Agent's possession relating to such funds or Cash
Equivalents or this Agreement.  If no successor escrow agent is appointed and
executes and delivers to the Escrow Agent an instrument of acceptance within 30
days of the notice of resignation, the Escrow Agent shall deliver all funds and
Cash Equivalents maintained by the Escrow Agent hereunder and originals of all
books, records, plans and other documents in the Escrow Agent's possession
relating to such funds or Cash Equivalents or this Agreement into a court of
competent jurisdiction.

       (Forming part of the terms and conditions of the Exchange Offer)
 
  1. Delivery of Letter of Transmittal and Certificates; Guaranteed Delivery
Procedures. This Letter of Transmittal is to be completed either if (a)
Certificates are to be forwarded herewith or (b) tenders are to be made
pursuant to the procedures for tender by book-entry transfer set forth in "The
Exchange Offer--Procedures for Tendering Outstanding Notes" in the Prospectus.
Certificates, or timely confirmation of a book-entry transfer of such
Outstanding Notes into the Exchange Agent's account at DTC, as well as this
Letter of Transmittal (or facsimile thereof), properly completed and duly
executed, with any required signature guarantees and any other documents
required by this Letter of Transmittal, must be received by the Exchange Agent
at its address set forth herein on or prior to the Expiration Date. The term
"book-entry confirmation" means a timely confirmation of book-entry transfer
of Outstanding Notes into the Exchange Agent's account at DTC. Outstanding
Notes may be tendered in whole or in part in integral multiples of $1,000
principal amount.
 
  Holders who wish to tender their Outstanding Notes and: (i) whose
Certificates for such Outstanding Notes are not immediately available; (ii)
who cannot deliver their Certificates, this Letter of Transmittal and all
other required documents to the Exchange Agent prior to the Expiration Date;
or (iii) who cannot complete the procedures for delivery by book-entry
transfer on a timely basis, may tender their Outstanding Notes by properly
completing and duly executing a Notice of Guaranteed Delivery pursuant to the
guaranteed delivery procedures set forth in "The Exchange Offer--Procedures
for Tendering Outstanding Notes" in the Prospectus. Pursuant to such
procedures: (i) such tender must be made by or through an Eligible Institution
(as defined below); (ii) a properly completed and duly executed Notice of
Guaranteed Delivery, substantially in the form accompanying this Letter of
Transmittal, must be received by the Exchange Agent prior to the Expiration
Date; and (iii) the Certificates (or a book-entry confirmation) representing
all tendered Outstanding Notes, in proper form for transfer, together with a
Letter of Transmittal (or facsimile thereof), properly completed and duly
executed, with any required signature guarantees and any other documents
required by this Letter of Transmittal, must be received by the Exchange Agent
within three New York Stock Exchange trading days after the date of execution
of such Notice of Guaranteed Delivery, all as provided in "The Exchange
Offer--Procedures for Tendering Outstanding Notes" in the Prospectus.
 
  The Notice of Guaranteed Delivery may be delivered by hand or transmitted by
facsimile or mail to the Exchange Agent and must include a guarantee by an
Eligible Institution in the form set forth in the Notice of Guaranteed
Delivery. For Outstanding Notes to be properly tendered pursuant to the
guaranteed delivery procedure, the Exchange Agent must receive a Notice of
Guaranteed Delivery prior to the Expiration Date. As used herein and in the
Prospectus, "Eligible Institution" means a firm or other entity identified in
Rule 17Ad-15 under the Exchange Act as "an eligible guarantor institution,"
including (as such terms are defined therein): (i) a bank; (ii) a broker,
dealer, municipal securities broker or dealer or government securities broker
or dealer; (iii) a credit union; (iv) a national securities exchange,
registered securities association or clearing agency; or (v) a savings
association that is a participant in a Securities Transfer Association.
 
  THE METHOD OF DELIVERY OF OUTSTANDING NOTES, THIS LETTER OF TRANSMITTAL AND
ALL OTHER REQUIRED DOCUMENTS IS AT THE OPTION AND SOLE RISK OF THE TENDERING
HOLDER, AND DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE
EXCHANGE AGENT. INSTEAD OF DELIVERY BY MAIL, IT IS RECOMMENDED THAT HOLDERS
USE AN OVERNIGHT OR HAND DELIVERY SERVICE. IN ALL CASES, SUFFICIENT TIME
SHOULD BE ALLOWED TO ASSURE TIMELY DELIVERY AND PROPER INSURANCE SHOULD BE
OBTAINED. NO LETTER OF TRANSMITTAL OR OUTSTANDING NOTES SHOULD BE SENT TO THE
AUTHORITY. HOLDERS MAY REQUEST THEIR RESPECTIVE BROKERS, DEALERS, COMMERCIAL
BANKS, TRUST COMPANIES OR NOMINEES TO EFFECT THESE TRANSACTIONS FOR SUCH
HOLDERS.
 
                                       8

  The Authority will not accept any alternative, conditional or contingent
tenders. Each tendering holder, by execution of a Letter of Transmittal (or
facsimile thereof), waives any right to receive any notice of the acceptance
of such tender.
 
  2. Guarantee of Signatures. No signature guarantee on this Letter of
Transmittal is required if: (i) this Letter of Transmittal is signed by the
registered holder (which shall include any participant in DTC whose name
appears on a security position listing as the owner of the Outstanding Notes)
of Outstanding Notes tendered herewith, unless such holder has completed
either the box entitled "Special Issuance Instructions" or the box entitled
"Special Delivery Instructions" above; or (ii) such Outstanding Notes are
tendered for the account of a firm that is an Eligible Institution. In all
other cases, an Eligible Institution must guarantee the signature(s) on this
Letter of Transmittal. See Instruction 5.
 
  3. Inadequate Space. If the space provided in the box captioned "Description
of Outstanding Notes Tendered" is inadequate, the Certificate number(s) and/or
the principal amount of Outstanding Notes and any other required information
should be listed on a separate signed schedule and attached to this Letter of
Transmittal.
 
  4. Partial Tenders and Withdrawal Rights. Tenders of Outstanding Notes will
be accepted only in integral multiples of $1,000 principal amount. If less
than all the Outstanding Notes evidenced by any Certificate submitted are to
be tendered, fill in the principal amount of Outstanding Notes which are to be
tendered in the box entitled "Principal Amount Tendered (if less than all)."
In such case, new Certificate(s) for the remainder of the Outstanding Notes
that were evidenced by the old Certificate(s) will be sent to the tendering
holder, unless the appropriate boxes on this Letter of Transmittal are
completed, promptly after the Expiration Date. All Outstanding Notes
represented by Certificates delivered to the Exchange Agent will be deemed to
have been tendered unless otherwise indicated.
 
  Except as otherwise provided herein, tenders of Outstanding Notes may be
withdrawn at any time prior to the Expiration Date. In order for a withdrawal
to be effective, a written, telegraphic or facsimile transmission of such
notice of withdrawal must be timely received by the Exchange Agent at its
address set forth above prior to the Expiration Date. Any such notice of
withdrawal must specify the name of the person who tendered the Outstanding
Notes to be withdrawn, the aggregate principal amount of Outstanding Notes to
be withdrawn, and (if Certificates for such Outstanding Notes have been
tendered) the name of the registered holder of the Outstanding Notes as set
forth on the Certificate(s), if different from that of the person who tendered
such Outstanding Notes. If Certificates for Outstanding Notes have been
delivered or otherwise identified to the Exchange Agent, the notice of
withdrawal must specify the serial numbers on the particular Certificates for
the Outstanding Notes to be withdrawn and the signature on the notice of
withdrawal must be guaranteed by an Eligible Institution, except in the case
of Outstanding Notes tendered for the account of an Eligible Institution. If
Outstanding Notes have been tendered pursuant to the procedures for book-entry
transfer set forth in "The Exchange Offer--Procedures for Tendering
Outstanding Notes," the notice of withdrawal must specify the name and number
of the account at DTC to be credited with the withdrawal of Outstanding Notes
and must otherwise comply with the procedures of DTC. Withdrawals of tenders
of Outstanding Notes may not be rescinded. Outstanding Notes properly
withdrawn will not be deemed validly tendered for purposes of the Exchange
Offer, but may be retendered at any subsequent time prior to the Expiration
Date by following any of the procedures described in the Prospectus under "The
Exchange Offer--Procedures for Tendering Outstanding Notes."
 
  All questions as to the validity, form and eligibility (including time of
receipt) of such withdrawal notices will be determined by the Authority, in
its sole discretion, which determination shall be final and binding on all
parties. Neither the Authority, any affiliates of the Authority, the Exchange
Agent or any other person shall be under any duty to give any notification of
any defects or irregularities in any notice
 
                                       9
<PAGE>
 
of withdrawal or incur any liability for failure to give any such
notification. Any Outstanding Notes which have been tendered but which are
withdrawn will be returned to the holder thereof promptly after withdrawal.
 
  5. Signatures on Letter of Transmittal, Assignments and Endorsements. If
this Letter of Transmittal is signed by the registered holder(s) of the
Outstanding Notes tendered hereby, the signature(s) must correspond exactly
with the name(s) as written on the face of the Certificate(s) or on a security
position listing, without alteration, enlargement or any change whatsoever.
 
  If any of the Outstanding Notes tendered hereby are owned of record by two
or more joint owners, all such owners must sign this Letter of Transmittal.
 
  If any tendered Outstanding Notes are registered in different names on
several Certificates, it will be necessary to complete, sign and submit as
many separate Letters of Transmittal (or facsimiles thereof) as there are
names in which Certificates are registered.
 
  If this Letter of Transmittal or any Certificates or bond powers are signed
by trustees, executors, administrators, guardians, attorneys-in-fact, officers
of corporations or others acting in a fiduciary or representative capacity,
such persons should so indicate when signing and must submit proper evidence
satisfactory to the Company, in its sole discretion, of such persons'
authority to so act.
 
  If this Letter of Transmittal is signed by a person other than the
registered holder(s) of the Outstanding Notes listed and transmitted hereby,
the Certificate(s) must be endorsed or accompanied by appropriate bond
power(s), signed exactly as the name(s) of the registered owner appear(s) on
the Certificate(s), and also must be accompanied by such opinions of counsel,
certifications and other information as the Company or the Trustee for the
Outstanding Notes may require in accordance with the restrictions on transfer
applicable to the Outstanding Notes. Signature(s) on such Certificate(s) or
bond power(s) must be guaranteed by an Eligible Institution.
 
  6. Special Issuance and Delivery Instructions. If Exchange Notes or
Certificates for Outstanding Notes not exchanged are to be issued in the name
of a person other than the signer of this Letter of Transmittal, or are to be
sent to someone other than the signer of this Letter of Transmittal or to an
address other than that shown above, the appropriate boxes on this Letter of
Transmittal should be completed. In the case of issuance in a different name,
the taxpayer identification number of the person named must also be indicated.
Holders tendering Outstanding Notes by book-entry transfer may request that
Outstanding Notes not exchanged be credited to such account maintained at DTC
as such holder may designate. If no such instructions are given, Outstanding
Notes not exchanged will be returned by mail or, if tendered by book-entry
transfer, by crediting the account indicated above maintained at DTC.
 
  7. Irregularities. The Authority will determine, in its sole discretion, all
questions as to the form of documents, validity, eligibility (including time
of receipt) and acceptance for exchange of any tender of Outstanding Notes,
which determination shall be final and binding on all parties. The Authority
reserves the absolute right, in its sole and absolute discretion, to reject
any and all tenders determined by it not to be in proper form or the
acceptance for exchange of which may, in the view of counsel to the Authority,
be unlawful. The Authority also reserves the absolute right, subject to
applicable law, to waive any of the conditions of the Exchange Offer set forth
in the Prospectus under "The Exchange Offer--Conditions to the Exchange Offer"
or any defect or irregularity in any tender of Outstanding Notes of any
particular holder whether or not similar defects or irregularities are waived
in the case of other holders. The Authority's interpretation of the terms and
conditions of the Exchange Offer (including this Letter of Transmittal and the
instructions hereto) will be final and binding. No tender of Outstanding Notes
will be deemed to have been validly made until all defects or irregularities
with respect to such tender have been cured or waived. Neither the Authority,
any affiliates of the Authority, the Exchange Agent, or any other person shall
be under any duty to give any notification of any defects or irregularities in
tenders or incur any liability for failure to give any such notification.

  8. Questions, Requests for Assistance and Additional Copies. Questions and
requests for assistance may be directed to the Exchange Agent at its address
and telephone number set forth above. Additional copies of the Prospectus, the
Notice of Guaranteed Delivery and the Letter of Transmittal may be obtained
from the Exchange Agent or from your broker, dealer, commercial bank, trust
company or other nominee.
 
  9. Backup Withholding; Substitute Form W-9. Under U.S. Federal income tax
law, a holder whose tendered Outstanding Notes are accepted for exchange is
required to provide the Exchange Agent with such holder's correct taxpayer
identification number ("TIN") on Substitute Form W-9 below. If the Exchange
Agent is not provided with the correct TIN, the Internal Revenue Service (the
"IRS") may subject the holder or other payee to a $50 penalty. In addition,
payments to such holders or other payees with respect to Outstanding Notes
exchanged pursuant to the Exchange Offer may be subject to 31% backup
withholding.
 
  The box in Part 3 of the Substitute Form W-9 may be checked if the tendering
holder has not been issued a TIN and has applied for a TIN or intends to apply
for a TIN in the near future. If the box in Part 3 is checked, the holder or
other payee must also complete the Certificate of Awaiting Taxpayer
Identification Number below in order to avoid backup withholding.
Notwithstanding that the box in Part 3 is checked and the Certificate of
Awaiting Taxpayer Identification Number is completed, the Exchange Agent will
withhold 31% of all payments made prior to the time a properly certified TIN
is provided to the Exchange Agent. The Exchange Agent will retain such amounts
withheld during the 60 day period following the date of the Substitute Form W-
9. If the holder furnishes the Exchange Agent with its TIN within 60 days
after the date of the Substitute Form W-9, the amounts retained during the 60
day period will be remitted to the holder and no further amounts shall be
retained or withheld from payments made to the holder thereafter. If, however,
the holder has not provided the Exchange Agent with its TIN within such 60 day
period, amounts withheld will be remitted to the IRS as backup withholding. In
addition, 31% of all payments made thereafter will be withheld and remitted to
the IRS until a correct TIN is provided.
 
  The holder is required to give the Exchange Agent the TIN (e.g., social
security number or employer identification number) of the registered owner of
the Outstanding Notes or of the last transferee appearing on the transfers
attached to, or endorsed on, the Outstanding Notes. If the Outstanding Notes
are registered in more than one name or are not in the name of the actual
owner, consult the Instructions to Form W-9 (Request for Identification Number
and Certification) for additional guidance on which number to report.
 
  Certain holders (including, among others, corporations, financial
institutions and certain foreign persons) may not be subject to these backup
withholding and reporting requirements. Such holders should nevertheless
complete the attached Substitute Form W-9 below, and write "exempt" on the
face thereof, to avoid possible erroneous backup withholding. A foreign person
may qualify as an exempt recipient by submitting a properly completed IRS Form
W-8, signed under penalties of perjury, attesting to that holder's exempt
status. Please consult the Instructions to Form W-9 (Request for
Identification Number and Certification) for additional guidance on which
holders are exempt from backup withholding.
 
  Backup withholding is not an additional U.S. federal income tax. Rather, the
U.S. federal income tax liability of a person subject to backup withholding
will be reduced by the amount of tax withheld. If withholding results in an
overpayment of taxes, a refund may be obtained.
 
  10. Mutilated, Lost, Destroyed or Stolen Certificates. If any Certificate
representing Outstanding Notes has been mutilated, lost, destroyed or stolen,
the holder should promptly notify the Exchange Agent. The holder will then be
instructed as to the steps that must be taken in order to replace the
Certificate. This Letter of Transmittal and related documents cannot be
processed until the procedures for replacing mutilated, lost, destroyed or
stolen Certificates have been followed.
 
                                      11

  11. Security Transfer Taxes. Holders who tender their Outstanding Notes for
exchange will not be obligated to pay any transfer taxes in connection
therewith, except that if Exchange Notes are to be delivered to, or are to be
issued in the name of, any person other than the registered holder of the
Outstanding Notes tendered, or if a transfer tax is imposed for any reason
other than the exchange of Outstanding Notes in connection with the Exchange
Offer, then the amount of any such transfer tax (whether imposed on the
registered holder or any other persons) will be payable by the tendering
holder. If satisfactory evidence of payment of such transfer tax or exemption
therefrom is not submitted with the Letter of Transmittal, the amount of such
transfer tax will be billed directly to such tendering holder.
 
  IMPORTANT: THIS LETTER OF TRANSMITTAL (OR A FACSIMILE THEREOF), TOGETHER
WITH CERTIFICATES REPRESENTING TENDERED OUTSTANDING NOTES OR A BOOK ENTRY
CONFIRMATION AND ALL OTHER REQUIRED DOCUMENTS, MUST BE RECEIVED BY THE
EXCHANGE AGENT PRIOR TO THE EXPIRATION DATE.

herewith.
 
  If tenders of Outstanding Notes are to be made by book-entry transfer to an

at The Depository Trust Company ("DTC"), instructions must be transmitted
through the DTC Automated Tender Offer Program (ATOP) pursuant to the

Prospectus and this Letter of Transmittal (together, the "Exchange Offer")
must transmit their acceptance to DTC which will edit and verify the
acceptance and execute a book-entry delivery to the Exchange Agent's account
at DTC, DTC will then send an Agent's Message to the Exchange Agent for its
acceptance. Delivery of the Agent's Message by DTC will satisfy the terms of
the Offer as the execution and delivery of a Letter of Transmittal by the
participant identified in the Agent's Message. DTC participants may also
accept the Exchange Offer by submitting a notice of guaranteed delivery
through ATOP.
 
  Holders of Outstanding Notes whose certificates (the "Certificates") for

  The undersigned hereby tenders to Mohegan Tribal Gaming Authority (the

exchange for a like principal amount of the Authority's 8 3/4% Senior

Transmittal (which, together with the Prospectus, constitute the "Exchange
Offer").
 
  Subject to and effective upon the acceptance for exchange of the Outstanding
Notes tendered herewith, the undersigned hereby sells, assigns and transfers
to or upon the order of the Authority all right, title and interest in and to
such Outstanding Notes as are being tendered herewith. The undersigned hereby
irrevocably constitutes and appoints the Exchange Agent as its agent and
attorney-in-fact (with full knowledge that the Exchange Agent is also acting
as agent of the Authority in connection with the Exchange Offer and as Trustee
under the Senior Subordinated Notes Indenture for the Outstanding Notes and
the Exchange Notes) with respect to the tendered Outstanding Notes, with full
power of substitution (such power of attorney being an irrevocable power
coupled with an interest), subject only to the right of withdrawal described
in the Prospectus, to: (i) deliver such Outstanding Notes to the Authority
together with all accompanying evidences of transfer and authenticity to, or
upon the order of, the Authority upon receipt by the Exchange Agent, as the
undersigned's agent, of the Exchange Notes to be issued in exchange for such
Outstanding Notes; (ii) present Certificates for such Outstanding Notes for
transfer, and to transfer such Outstanding Notes on the account books
maintained by DTC; and (iii) receive for the account of the Company all

AND THAT THE OUTSTANDING NOTES TENDERED HEREBY ARE NOT SUBJECT TO ANY ADVERSE
CLAIMS OR PROXIES. THE UNDERSIGNED WILL, UPON REQUEST, EXECUTE AND DELIVER ANY
ADDITIONAL DOCUMENTS DEEMED BY THE COMPANY OR THE EXCHANGE AGENT TO BE
NECESSARY OR DESIRABLE TO COMPLETE THE EXCHANGE, SALE, ASSIGNMENT AND TRANSFER
OF THE OUTSTANDING NOTES TENDERED HEREBY. THE UNDERSIGNED HAS READ AND AGREES

Notes. The Certificate number(s) and the Outstanding Notes that the
undersigned wishes to tender should be indicated in the appropriate boxes

  If any tendered Outstanding Notes are not exchanged pursuant to the Exchange
Offer for any reason, or if Certificates are submitted for more Outstanding
Notes than are tendered or accepted for exchange, Certificates for such
nonexchanged or nontendered Outstanding Notes will be returned (or, in the
case of Outstanding Notes tendered by book-entry transfer, such Outstanding
Notes will be credited to an account maintained at DTC), without expense to

SECURITIES ACT). THE COMPANY HAS AGREED THAT STARTING ON THE EXPIRATION DATE
AND ENDING ON THE CLOSE OF BUSINESS ON THE FIRST ANNIVERSARY OF THE EXPIRATION
DATE, IT WILL MAKE THE PROSPECTUS AVAILABLE TO ANY PARTICIPATING BROKER-DEALER
IN CONNECTION WITH ANY SUCH RESALE.

Transmittal shall survive the death or incapacity of the undersigned and any
obligation of the undersigned hereunder shall be binding upon the heirs,

set forth in "The Exchange Offer--Procedures for Tendering Outstanding Notes"
in the Prospectus instructions must be transmitted through the DTC Automated

properly completed and duly executed, with any required signature guarantees
and any other documents required by this Letter of Transmittal, must be
received by the Exchange Agent at its address set forth herein on or prior to
the Expiration Date. The term "book-entry confirmation" means a timely
confirmation of book-entry transfer of Outstanding Notes into the Exchange
Agent's account at DTC. Outstanding Notes may be tendered in whole or in part
in integral multiples of $1,000 principal amount.
 
  Holders who wish to tender their Outstanding Notes and: (i) whose
Certificates for such Outstanding Notes are not immediately available; (ii)
who cannot deliver their Certificates, this Letter of Transmittal and all
other required documents to the Exchange Agent prior to the Expiration Date;
or (iii) who cannot complete the procedures for delivery by book-entry
transfer on a timely basis, may tender their Outstanding Notes by properly
completing and duly executing a Notice of Guaranteed Delivery pursuant to the
guaranteed delivery procedures set forth in "The Exchange Offer--Procedures
for Tendering Outstanding Notes" in the Prospectus. Pursuant to such
procedures: (i) such tender must be made by or through an Eligible Institution
(as defined below); (ii) a properly completed and duly executed Notice of
Guaranteed Delivery, substantially in the form accompanying this Letter of
Transmittal, or an Agent's message with respect to guaranteed delivery that is
accepted by the Company must be received by the Exchange Agent prior to the
Expiration Date; and (iii) the Certificates (or a book-entry confirmation)
representing all tendered Outstanding Notes, in proper form for transfer,
together with a Letter of Transmittal (or facsimile thereof), or in the case
of a book-entry transfer, a properly transmitted Agent's message and duly
executed, with any required signature guarantees and any other documents
required by this Letter of Transmittal, must be received by the Exchange Agent
within three New York Stock Exchange trading days after the date of execution
of such Notice of Guaranteed Delivery, all as provided in "The Exchange
Offer--Procedures for Tendering Outstanding Notes" in the Prospectus.
 
  The Notice of Guaranteed Delivery may be delivered by hand or transmitted by
facsimile or mail to the Exchange Agent and must include a guarantee by an
Eligible Institution in the form set forth in the Notice of Guaranteed
Delivery. For Outstanding Notes to be properly tendered pursuant to the
guaranteed delivery procedure, the Exchange Agent must receive a Notice of
Guaranteed Delivery prior to the Expiration Date. As used herein and in the
Prospectus, "Eligible Institution" means a firm or other entity identified in
Rule 17Ad-15 under the Exchange Act as "an eligible guarantor institution,"

programs: 1. the Securities Transfer Agents Medallion Program (STAMP) 2. the
New York Stock Exchange Medallion Signature Program (MSP) 3. the Stock
Exchanges Medallion Program (SEMP).
 
  THE METHOD OF DELIVERY OF OUTSTANDING NOTES, THIS LETTER OF TRANSMITTAL AND
ALL OTHER REQUIRED DOCUMENTS IS AT THE OPTION AND SOLE RISK OF THE TENDERING
HOLDER, AND DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE
EXCHANGE AGENT. INSTEAD OF DELIVERY BY MAIL, IT IS RECOMMENDED THAT HOLDERS
USE AN OVERNIGHT OR HAND DELIVERY SERVICE. IN ALL CASES, SUFFICIENT TIME
SHOULD BE ALLOWED TO ASSURE TIMELY DELIVERY AND PROPER INSURANCE SHOULD BE
OBTAINED. NO

<PAGE>
 
LETTER OF TRANSMITTAL OR OUTSTANDING NOTES SHOULD BE SENT TO THE AUTHORITY.
HOLDERS MAY REQUEST THEIR RESPECTIVE BROKERS, DEALERS, COMMERCIAL BANKS, TRUST
COMPANIES OR NOMINEES TO EFFECT THESE TRANSACTIONS FOR SUCH HOLDERS.
 
  The Authority will not accept any alternative, conditional or contingent
tenders. Each tendering holder, by execution of a Letter of Transmittal (or
execution thereof on ATOP), waives any right to receive any notice of the
acceptance of such tender.
 
  2. Guarantee of Signatures. No signature guarantee on this Letter of
Transmittal is required if: (i) this Letter of Transmittal is signed by the
registered holder (which shall include any participant in DTC whose name
appears on a security position listing as the owner of the Outstanding Notes)
of Outstanding Notes tendered herewith, unless such holder has completed
either the box entitled "Special Issuance Instructions" or the box entitled
"Special Delivery Instructions" above; or (ii) such Outstanding Notes are
tendered for the account of a firm that is an Eligible Institution. In all
other cases, an Eligible Institution must guarantee the signature(s) on this
Letter of Transmittal. See Instruction 5.
 
  3. Inadequate Space. If the space provided in the box captioned "Description
of Outstanding Notes Tendered" is inadequate, the Certificate number(s) and/or
the principal amount of Outstanding Notes and any other required information
should be listed on a separate signed schedule and attached to this Letter of
Transmittal.
 
  4. Partial Tenders and Withdrawal Rights. (Not applicable to Holders who
tender by book-entry transfer). Tenders of Outstanding Notes will be accepted
only in integral multiples of $1,000 principal amount. If less than all the
Outstanding Notes evidenced by any Certificate submitted are to be tendered,
fill in the principal amount of Outstanding Notes which are to be tendered in
the box entitled "Principal Amount Tendered (if less than all)." In such case,
new Certificate(s) for the remainder of the Outstanding Notes that were
evidenced by the old Certificate(s) will be sent to the tendering holder,
unless the appropriate boxes on this Letter of Transmittal are completed,
promptly after the Expiration Date. All Outstanding Notes represented by
Certificates delivered to the Exchange Agent will be deemed to have been
tendered unless otherwise indicated.
 
  Except as otherwise provided herein, tenders of Outstanding Notes may be
withdrawn at any time prior to the Expiration Date. In order for a withdrawal
to be effective, a written, telegraphic or facsimile transmission of such
notice of withdrawal must be timely received by the Exchange Agent at its
address set forth above prior to the Expiration Date. Any such notice of
withdrawal must specify the name of the person who tendered the Outstanding
Notes to be withdrawn, the aggregate principal amount of Outstanding Notes to
be withdrawn, and (if Certificates for such Outstanding Notes have been
tendered) the name of the registered holder of the Outstanding Notes as set
forth on the Certificate(s), if different from that of the person who tendered
such Outstanding Notes. If Certificates for Outstanding Notes have been
delivered or otherwise identified to the Exchange Agent, the notice of
withdrawal must specify the serial numbers on the particular Certificates for
the Outstanding Notes to be withdrawn and the signature on the notice of
withdrawal must be guaranteed by an Eligible Institution, except in the case
of Outstanding Notes tendered for the account of an Eligible Institution. If
Outstanding Notes have been tendered pursuant to the procedures for book-entry
transfer set forth in "The Exchange Offer--Procedures for Tendering
Outstanding Notes," the notice of withdrawal must specify the name and number
of the account at DTC to be credited with the withdrawal of Outstanding Notes
and must otherwise comply with the procedures of DTC. Withdrawals of tenders
of Outstanding Notes may not be rescinded. Outstanding Notes properly
withdrawn will not be deemed validly tendered for purposes of the Exchange
Offer, but may be retendered at any subsequent time prior to the Expiration
Date by following any of the procedures described in the Prospectus under "The
Exchange Offer--Procedures for Tendering Outstanding Notes."

  All questions as to the validity, form and eligibility (including time of
receipt) of such withdrawal notices will be determined by the Authority, in
its sole discretion, which determination shall be final and binding on all
parties. Neither the Authority, any affiliates of the Authority, the Exchange
Agent or any other person shall be under any duty to give any notification of
any defects or irregularities in any notice of withdrawal or incur any
liability for failure to give any such notification. Any Outstanding Notes
which have been tendered but which are withdrawn will be returned to the
holder thereof promptly after withdrawal.
 
  5. Signatures on Letter of Transmittal, Assignments and Endorsements. If
this Letter of Transmittal is signed by the registered holder(s) of the
Outstanding Notes tendered hereby, the signature(s) must correspond exactly
with the name(s) as written on the face of the Certificate(s) or on a security
position listing, without alteration, enlargement or any change whatsoever.
 
  If any of the Outstanding Notes tendered hereby are owned of record by two
or more joint owners, all such owners must sign this Letter of Transmittal.
 
  If any tendered Outstanding Notes are registered in different names on
several Certificates, it will be necessary to complete, sign and submit as
many separate Letters of Transmittal (or facsimiles thereof) as there are
names in which Certificates are registered.
 
  If this Letter of Transmittal or any Certificates or bond powers are signed
by trustees, executors, administrators, guardians, attorneys-in-fact, officers
of corporations or others acting in a fiduciary or representative capacity,
such persons should so indicate when signing and must submit proper evidence
satisfactory to the Company, in its sole discretion, of such persons'
authority to so act.
 
  If this Letter of Transmittal is signed by a person other than the
registered holder(s) of the Outstanding Notes listed and transmitted hereby,
the Certificate(s) must be endorsed or accompanied by appropriate bond
power(s), signed exactly as the name(s) of the registered owner appear(s) on
the Certificate(s), and also must be accompanied by such opinions of counsel,
certifications and other information as the Company or the Trustee for the
Outstanding Notes may require in accordance with the restrictions on transfer
applicable to the Outstanding Notes. Signature(s) on such Certificate(s) or
bond power(s) must be guaranteed by an Eligible Institution.
 
  6. Special Issuance and Delivery Instructions. If Exchange Notes or
Certificates for Outstanding Notes not exchanged are to be issued in the name
of a person other than the signer of this Letter of Transmittal, or are to be
sent to someone other than the signer of this Letter of Transmittal or to an
address other than that shown above, the appropriate boxes on this Letter of
Transmittal should be completed. In the case of issuance in a different name,
the taxpayer identification number of the person named must also be indicated.
Holders tendering Outstanding Notes by book-entry transfer may request that
Outstanding Notes not exchanged be credited to such account maintained at DTC
as such holder may designate. If no such instructions are given, Outstanding
Notes not exchanged will be returned by mail or, if tendered by book-entry
transfer, by crediting the account indicated above maintained at DTC.
 
  7. Irregularities. The Authority will determine, in its sole discretion, all
questions as to the form of documents, validity, eligibility (including time
of receipt) and acceptance for exchange of any tender of Outstanding Notes,
which determination shall be final and binding on all parties. The Authority
reserves the absolute right, in its sole and absolute discretion, to reject
any and all tenders determined by it not to be in proper form or the
acceptance for exchange of which may, in the view of counsel to the Authority,
be unlawful. The Authority also reserves the absolute right, subject to
applicable law, to waive any of the conditions of the Exchange Offer set forth
in the Prospectus under "The Exchange Offer--Conditions to the Exchange Offer"
or any defect or irregularity in any tender of Outstanding Notes of any
particular holder whether or not similar defects or irregularities are waived
in the case of other holders. The Authority's interpretation of the terms and
conditions of the
 
                                      10
<PAGE>
 
Exchange Offer (including this Letter of Transmittal and the instructions
hereto) will be final and binding. No tender of Outstanding Notes will be
deemed to have been validly made until all defects or irregularities with
respect to such tender have been cured or waived. Neither the Authority, any
affiliates of the Authority, the Exchange Agent, or any other person shall be
under any duty to give any notification of any defects or irregularities in
tenders or incur any liability for failure to give any such notification.
 
  8. Questions, Requests for Assistance and Additional Copies. Questions and
requests for assistance may be directed to the Exchange Agent at its address
and telephone number set forth above. Additional copies of the Prospectus, the
Notice of Guaranteed Delivery and the Letter of Transmittal may be obtained
from the Exchange Agent or from your broker, dealer, commercial bank, trust
company or other nominee.
 
  9. Backup Withholding; Substitute Form W-9. Under U.S. Federal income tax
law, a holder whose tendered Outstanding Notes are accepted for exchange is
required to provide the Exchange Agent with such holder's correct taxpayer
identification number ("TIN") on Substitute Form W-9 below. If the Exchange
Agent is not provided with the correct TIN, the Internal Revenue Service (the
"IRS") may subject the holder or other payee to a $50 penalty. In addition,
payments to such holders or other payees with respect to Outstanding Notes
exchanged pursuant to the Exchange Offer may be subject to 31% backup
withholding.
 
  The box in Part 3 of the Substitute Form W-9 may be checked if the tendering
holder has not been issued a TIN and has applied for a TIN or intends to apply
for a TIN in the near future. If the box in Part 3 is checked, the holder or
other payee must also complete the Certificate of Awaiting Taxpayer
Identification Number below in order to avoid backup withholding.
Notwithstanding that the box in Part 3 is checked and the Certificate of
Awaiting Taxpayer Identification Number is completed, the Exchange Agent will
withhold 31% of all payments made prior to the time a properly certified TIN
is provided to the Exchange Agent. The Exchange Agent will retain such amounts
withheld during the 60 day period following the date of the Substitute Form W-
9. If the holder furnishes the Exchange Agent with its TIN within 60 days
after the date of the Substitute Form W-9, the amounts retained during the 60
day period will be remitted to the holder and no further amounts shall be
retained or withheld from payments made to the holder thereafter. If, however,
the holder has not provided the Exchange Agent with its TIN within such 60 day
period, amounts withheld will be remitted to the IRS as backup withholding. In
addition, 31% of all payments made thereafter will be withheld and remitted to
the IRS until a correct TIN is provided.
 
  The holder is required to give the Exchange Agent the TIN (e.g., social
security number or employer identification number) of the registered owner of
the Outstanding Notes or of the last transferee appearing on the transfers
attached to, or endorsed on, the Outstanding Notes. If the Outstanding Notes
are registered in more than one name or are not in the name of the actual
owner, consult the Instructions to Form W-9 (Request for Identification Number
and Certification) for additional guidance on which number to report.
 
  Certain holders (including, among others, corporations, financial
institutions and certain foreign persons) may not be subject to these backup
withholding and reporting requirements. Such holders should nevertheless
complete the attached Substitute Form W-9 below, and write "exempt" on the
face thereof, to avoid possible erroneous backup withholding. A foreign person
may qualify as an exempt recipient by submitting a properly completed IRS Form
W-8, signed under penalties of perjury, attesting to that holder's exempt
status. Please consult the Instructions to Form W-9 (Request for
Identification Number and Certification) for additional guidance on which
holders are exempt from backup withholding.
 
 
                                      11
<PAGE>
 
  Backup withholding is not an additional U.S. federal income tax. Rather, the
U.S. federal income tax liability of a person subject to backup withholding
will be reduced by the amount of tax withheld. If withholding results in an
overpayment of taxes, a refund may be obtained.
 
  10. Mutilated, Lost, Destroyed or Stolen Certificates. If any Certificate
representing Outstanding Notes has been mutilated, lost, destroyed or stolen,
the holder should promptly notify the Exchange Agent. The holder will then be
instructed as to the steps that must be taken in order to replace the
Certificate. This Letter of Transmittal and related documents cannot be
processed until the procedures for replacing mutilated, lost, destroyed or
stolen Certificates have been followed.
 
  11. Security Transfer Taxes. Holders who tender their Outstanding Notes for
exchange will not be obligated to pay any transfer taxes in connection
therewith, except that if Exchange Notes are to be delivered to, or are to be
issued in the name of, any person other than the registered holder of the
Outstanding Notes tendered, or if a transfer tax is imposed for any reason
other than the exchange of Outstanding Notes in connection with the Exchange
Offer, then the amount of any such transfer tax (whether imposed on the
registered holder or any other persons) will be payable by the tendering
holder. If satisfactory evidence of payment of such transfer tax or exemption
therefrom is not submitted with the Letter of Transmittal, the amount of such
transfer tax will be billed directly to such tendering holder.
 
  IMPORTANT: THIS LETTER OF TRANSMITTAL (OR A FACSIMILE THEREOF), TOGETHER
WITH CERTIFICATES REPRESENTING TENDERED OUTSTANDING NOTES OR A BOOK ENTRY
CONFIRMATION AND ALL OTHER REQUIRED DOCUMENTS, MUST BE RECEIVED BY THE
EXCHANGE AGENT PRIOR TO THE EXPIRATION DATE.
