                                    PART I
 
ITEM 1. BUSINESS
 
A. GENERAL
 
  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 is a federally recognized Indian tribe with a 390-
acre reservation located in southeastern Connecticut.
 
  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 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 Casino ("Mohegan Sun").
 
  The Authority is governed by a Management Board, which consists of the nine
members of the Tribal Council. The Management Board engaged Trading Cove
Associates ("TCA"), a Connecticut general partnership, to operate, manage and
market Mohegan Sun under a seven-year contract ("Management Agreement"). TCA's
management fee under the Management Agreement ranges from 30% to 40% of net
income before management fee, depending on profitability thresholds. TCA is
50% owned by Sun Cove Limited, an affiliate of Sun International Hotels
Limited ("Sun International"), and 50% by Waterford Gaming, L.L.C. The
Management Board also selects tribal representatives to serve on a Business
Board (the "Business Board") which oversees the business aspects of Mohegan
Sun. The Business Board is established under the Management Agreement and
consists of two members appointed by the Management Board and two members
appointed by TCA. In February 1998, the Authority and TCA entered into a new
agreement ("Relinquishment Agreement") which will supercede the Management
Agreement effective January 1, 2000. The Bureau of Indian Affairs (the "BIA")
determined on October 23, 1998 that the Relinquishment Agreement did not
require the approval of the BIA. As a result of the Relinquishment Agreement,
the Authority has agreed to pay TCA 5% of gross revenues (as defined in the
agreement) generated from Mohegan Sun and from the planned expansion,
beginning January 1, 2000 and ending December 31, 2014. See Note 13 to the
Authority's Financial Statements included in Part II of this report for
valuation of this liability.
 
  The Authority has established the Mohegan Tribal Gaming Commission (the
"Commission"), which is responsible for the regulation of gaming activities of
Mohegan Sun. The Commission ensures the integrity of the gaming operation
through the promulgation and enforcement of appropriate regulations. The
Commission staff is responsible for performing background investigations on
gaming license applicants and for issuance and revocation of such gaming
licenses.
 
  The Tribe and the Authority have entered into a land lease pursuant to which
the Tribe is leasing to the Authority the land site on which Mohegan Sun is
located. The site is a part of the Tribe's 390-acre reservation in
southeastern Connecticut, which was acquired and is held in trust for the
Tribe by the United States of America with the Tribe retaining perpetual
rights to the use of the site.
 
B. DESCRIPTION OF BUSINESS
 
GAMING
 
  Mohegan Sun opened on October 12, 1996 as a full-service gaming and
entertainment facility. Mohegan Sun conveys historical northeastern Indian
theming through architectural features and the use of natural design elements
such as timber, stone and water. Celebrating the history and traditions of the
Tribe, Mohegan Sun's circular design and Indian theming are directly
influenced by the Tribe's beliefs and culture. The casino is comprised of four
quadrants, each of which features its own entrance and a seasonal theme. Each
of the seasons,
 
                                       1
<PAGE>
 
winter, spring, summer and fall, emphasize the importance of seasonal changes
to Mohegan Tribal life. The 634,500 square foot facility includes 176,500
square feet of gaming space and accommodates 3,029 slot machines, 150 table
games (including blackjack, roulette, craps, baccarat, caribbean stud poker
and let it ride), 42 poker tables, a race book area and a 1,400 seat high
stakes bingo hall. For the year ended September 30, 1998, the Authority
welcomed 7.5 million patrons.
 
  Food amenities at Mohegan Sun include the 680-seat Seasons buffet, three
themed gourmet restaurants, a 24-hour full service coffee shop, a New York
style delicatessen and a 10-station food court featuring international and
domestic cuisine. The bingo hall also serves as a special events center which
is utilized for entertainment, boxing events and casino marketing events. The
10,000 square foot Wolf Den Lounge (the "Wolf Den"), located in the center of
Mohegan Sun, features live entertainment seven days a week. The Wolf Den seats
350 patrons. Multiple full-service and floor service bars are located
throughout the facility. Mohegan Sun also offers a children's arcade area and
New Horizons Kids Quest, Inc., a child care facility. There are approximately
7,500 parking spaces for customers, along with 1,700 employee parking spaces.
 
  The Authority opened a 4,000 square foot gas station facility on December 7,
1998. The facility consists of 16 gasoline pumps, one diesel fuel pump, and a
convenience store that offers fresh baked goods and retail items and maintains
a historical Indian theme. Patrons may pay at the pump or utilize their
accumulated complimentary points to pay for the gasoline. The cost of the
facility was approximately $5.9 million and was financed through equipment
leasing and internally generated funds.
 
  On February 7, 1998, the Authority finalized contract negotiations on a
development agreement with TCA and is moving forward with an expansion project
("Phase II"), at Mohegan Sun which is currently 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. These firms, in conjunction with
the Tribe, are in the process of developing a construction budget and
schedule. As a result, the estimated project cost range is still subject to
adjustment. Phase II is expected to break ground in the spring of 1999. See
Note 13 to the Authority's Financial Statements for details of the Development
Agreement.
 
 Seasonality
 
  The gaming industry in Connecticut is seasonal, with the heaviest gaming
activity at Mohegan Sun occurring during the period from July through October.
 
COMPETITION FROM OTHER GAMING OPERATIONS
 
  The gaming industry is highly competitive. Mohegan Sun currently competes
primarily with Foxwoods Resort Casino ("Foxwoods") 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 (the "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.
 
  Mohegan Sun's current market area is predominantly for day-trip customers.
Upon the completion of the expansion, however, the Authority intends to
broaden its market beyond day-trip customers to include patrons making
overnight or extended stays at Mohegan Sun. This means the Authority will
begin to compete for customers more directly with casinos in Atlantic City,
New Jersey. Many of these casinos and other gaming resorts may have greater
resources and greater name recognition than the Authority.
 
  Outside of Atlantic City, New Jersey, casino gaming in the northeastern
United States may be conducted only by federally recognized Indian tribes
operating under the federal Indian gaming law. Currently, the Oneida
 
                                       2
<PAGE>
 
Indian Nation operates Turning Stone Casino Resort in Verona, New York,
approximately 270 miles from Mohegan Sun. 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 in order 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 operations by the
Authority.
 
  The following is an assessment of the competitive prospects in Connecticut,
each of the Authority's neighboring states and certain other states in the
Northeast.
 
 Connecticut
 
  Currently, only the Tribe and the Pequot Tribe are authorized to conduct
gaming in Connecticut. As required by their state compacts, the Tribe and the
Pequot Tribe make monthly payments to the State of Connecticut based on 25% of
annual slot win. Together, these payments totaled over $266.1 million in the
12 months ended September 30, 1998. The Authority contributed $102.3 million
during that period. These payments are linked to an exclusivity clause and
will terminate if the State legalizes other gaming operations, (except those
consented to by the Tribe and/or the Pequot Tribe) with slot machines or other
commercial casino table games. There are currently at least four tribes in
Connecticut that are attempting to gain federal recognition, a lengthy process
managed by the BIA. Two of these are the Eastern Pequot and/or the Paucatuck
Eastern Pequot Tribe, who share a reservation located next to that of the
Pequot Tribe. 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 casino 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, with a reservation in Charlestown, 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. Thus, the Narragansett Tribe could open a facility only if it were
successful in winning both local and state-wide votes. There is one pending
federal recognition petition from another Rhode Island tribe, filed by the
Pokanoket Tribe of the Wampanoag Nation. 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. The tribe has announced plans to open a high-stakes bingo facility in
Fall River, for which no state compact would be required, but significant
hurdles, including local government approval still remain. In addition, a
number of other petitions for federal recognition are pending in
Massachusetts, but the Tribe believes potential recognition is several years
away.
 
 
                                       3

 New York
 
  There currently are no non-Indian casinos operating 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,
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.
Manhattan Cruises was the first operator to receive a license. 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 tribes with reservations in the northern part of
the state. 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 and 285 hotel rooms. Turning Stone currently draws
primarily from the Syracuse, New York market and does not compete directly
with Mohegan Sun for customers. The St. Regis Mohawk Tribe, which has a
reservation in Hogansburg on the Canadian border, has not yet opened a gaming
facility; however, a management contract is under review at the National
Indian Gaming Commission (the "NIGC"). The St. Regis Mohawk Tribe and
officials from Sullivan County have also signed an agreement that contemplates
the establishment of a tribal operated casino at the Monticello Raceway in the
Catskills (located approximately 170 miles from Mohegan Sun), but the Governor
of New York has not indicated that he would support this proposal. 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, New York and Gowanda, New York, both over 400 miles from Mohegan
Sun. 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 Penobscott Tribe)
opened a high stakes bingo facility in the township of Albany in western
Maine. None of the federally recognized tribes have 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 no significant initiatives
currently underway to facilitate legalization. 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 no significant initiatives
currently underway to allow legislation. 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. The Authority believes any
approval is still several years away.
 
EMPLOYEES AND LABOR RELATIONS
 
  As of September 30, 1998, Mohegan Sun employed approximately 4,743 full time
employees, and 322 seasonal and part-time employees. In recruiting personnel,
Mohegan Sun is obligated to give preference first to qualified members of the
Tribe (and qualified spouses of members of the Tribe) and second to
 
                                       4
<PAGE>
 
members of other federally recognized Indian tribes. None of Mohegan Sun's
employees are covered by collective bargaining agreements.
 
MATERIAL AGREEMENTS
 
 The Mohegan Compact
 
  The Tribe and the State of Connecticut entered into the Mohegan Compact that
authorizes and regulates Class III gaming operations on land owned by the
Tribe. Certain key provisions of the Mohegan Compact are summarized below:
 
    (1) The Tribe agrees to submit all gaming-related operation and
  development to the regulation of the State of Connecticut Gaming Commission
  (i.e. the Division of Special Revenue) in order to ensure the fair and
  honest operation of gaming activities and to maintain the integrity of
  Class III gaming activities.
 
    (2) The Tribe may conduct, on the site, games of chance, including:
  blackjack, poker, craps, money-wheels, roulette, baccarat, sic-bo, pai gow,
  caribbean stud, horse race game, acey-ducey, casino war, slot machines,
  video facsimile games and pari-mutuel betting.
 
    (3) Law enforcement matters relating to Class III gaming activities are
  under the jurisdiction of the State of Connecticut and the Tribe.
 
    (4) All gaming employees will obtain and maintain a gaming license issued
  by the Connecticut Division of Special Revenue.
 
    (5) Any enterprise providing gaming services or gaming equipment to the
  Tribe will be required to hold a current valid registration issued by the
  Connecticut Division of Special Revenue.
 
    (6) The State of Connecticut will annually assess the Tribe for the costs
  attributable to its regulation of the Tribe's gaming operations and for the
  provision of law enforcement.
 
    (7) The Tribe will have its Class III gaming operations audited on an
  annual basis by an independent certified public accountant and include any
  additional procedures required by the State of Connecticut Gaming
  Commission.
 
    (8) The Tribe will enact fire, building, sanitary and health ordinances
  and regulations no less rigorous than laws and regulations of the State of
  Connecticut.
 
    (9) Service of alcoholic beverages within any gaming facility will be
  subject to regulation by the State of Connecticut.
 
    (10) The Tribe waives any defense which it may have by virtue of
  sovereign immunity in respect to any action in United States District Court
  to enforce the Mohegan Compact.
 
 Memorandum of Understanding
 
  The Tribe and the State of Connecticut entered into a Memorandum of
Understanding ("MOU") setting forth certain matters regarding the
implementation of the Mohegan Compact. The MOU provides that, so long as there
is no change in State law to permit the operation of slot machines or other
commercial casino table games by any other person (except those consented to
by the Tribe and/or the Pequot Tribe), the Tribe, through the Authority, will
contribute to the State of Connecticut on a monthly basis a sum equal to 25%
of gross operating revenues derived from slot machines operated by the
Authority ("Slot Win Contribution"). The MOU also states that on an annual
basis, the minimum Slot Win Contribution of the Authority to the State of
Connecticut 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) $80,000,000. For the fiscal year ending September 30, 1998, the
Tribe's Slot Win Contribution paid by the Authority totaled approximately
$102.3 million.
 
 
                                       5
<PAGE>
 
 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, beginning one
year after the commencement of slot machine gaming activities, an annual
payment of $500,000 to minimize the impact to the Town resulting from
decreased tax revenues on reservation land held in trust. The first and second
annual payments were remitted to the Town in October 1997 and 1998,
respectively. Additionally, the Tribe agreed to make a one-time payment of
$3.0 million toward infrastructure improvements in 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
Town of Montville had billed and received payment for approximately $1.1
million of the $3.0 million obligation.
 
 Management Agreement
 
  The Tribe and TCA entered into the Management Agreement, pursuant to which
the Tribe retained and engaged TCA to operate, manage and market Mohegan Sun.
The Tribe assigned its rights and obligations in the Management Agreement to
the Authority. The term of the Management Agreement is seven years. TCA will
manage Mohegan Sun in exchange for payments ranging from 30% to 40% of net
income, before management fee, depending upon profitability thresholds.
 
 Relinquishment and Development Agreements
 
  On February 7, 1998, the Authority finalized the Relinquishment Agreement
with TCA. Under the Relinquishment Agreement, effective the later of January
1, 2000, or the date the existing Series B Senior Secured Notes of the
Authority in the original aggregate principal amount of $175 million are
refinanced or repaid, the Management Agreement will terminate and the
Authority will assume day-to-day management of Mohegan Sun. The Authority has
agreed to pay to TCA 5% of gross revenues (as defined in the agreement)
generated from Mohegan Sun and a planned expansion, beginning January 1, 2000
and ending December 31, 2014.
 
  The Authority has also negotiated a second agreement with TCA (the
"Development Agreement"), which makes TCA the exclusive developer of Phase II.
Under the Development Agreement, TCA will oversee the planning, design and
construction of Phase II and will receive compensation of $14 million for such
services.
 
  See Note 13 of the Authority's Financial Statements for details of the
Management, Relinquishment and Development Agreements.
 
ITEM 2. PROPERTIES
 
  Mohegan Sun is located on 240 acres of the Tribe's reservation just outside
of Uncasville, CT, approximately one mile from the interchange of Interstate
395 and Connecticut Route 2A. Mohegan Sun has its own exit from Route 2A,
giving patrons direct access to Interstate 395 and Interstate 95, the main
highway connecting Boston, Providence, and New York. By highway, Mohegan Sun
is approximately 115 miles from New York City, 95 miles from Boston,
Massachusetts, 35 miles from Hartford, Connecticut and 50 miles from
Providence, Rhode Island.
 
  Parking at Mohegan Sun is provided through surface parking lots and a multi-
level parking garage accommodating approximately 7,500 vehicles. Traffic
enters the grounds via a four-lane access road on Route 2A and is directed to
the valet parking drop-off zones or to the self-park surface lots (including
the parking garage) which are connected to the main building by shuttle bus
service. A separate loading and parking area is designated for bus groups.
 
  The Authority has a lease with the Tribe for land on which Mohegan Sun is
located. The initial term of the lease is 25 years, with an option to renew
for one additional 25-year term provided that the Authority is not in default
under the lease. The lease also provides that all improvements constructed on
the site will become the property of the Tribe. The lease is a net lease
requiring that the Authority assume all costs of operating,
 
                                       6

constructing, maintaining, repairing, replacing and insuring the leased
property, in addition to the payment of a nominal annual rental fee.
 
  The Authority has entered into four other lease agreements for properties
adjacent to Mohegan Sun. The properties are owned by MTIC Acquisitions,
L.L.C., a Connecticut limited liability company controlled by the Tribe. The
properties are used for providing access and/or parking for Mohegan Sun. The
leases are for terms of five to ten years with options to extend beyond the
term. The aggregate lease payments per year for such properties is $636,000,
and the Authority is responsible for maintenance and repair thereon.
 
ITEM 3. LEGAL PROCEEDINGS
 
  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.
 
ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS
 
  Pursuant to Section 4.28 of the Indenture for the $175 million Senior
Secured Notes due 2002, the Authority is required to make an Excess Cash
Purchase Offer to all Holders of the notes within 120 days of the Authority's
fiscal year end. In March 1998, the Authority made an offer valued at $29.1
million to purchase back a portion of the outstanding Senior Secured Notes.
The offer was declined by security holders, and the excess cash was
distributed to the Tribe on April 2, 1998.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS
 
RESULTS OF OPERATIONS
 
 Overview of Fiscal Year Ended September 30, 1998 and Period from October 12,
1996 (date of commencement of operations) through September 30, 1997
 
  Gaming revenues for fiscal 1998 and fiscal 1997 were $543.9 million and
$440.5 million, respectively. For the year ended September 30, 1998, net
operating revenues were $575.1 million versus net operating revenues of $467.8
million for the period ended September 30, 1997. The facility began the year
with 2,962 slot machines available for gaming activity on the casino floor.
During the fiscal year, 67 additional slot machines were placed on the casino
floor, bringing the total year-end number of machines to 3,029. The win per
slot unit per day for the year ended September 30, 1998 and for the period
ended September 30, 1997 were $361 and $319, respectively. This resulted in
fiscal year 1998 total slot revenues of $396.3 million versus total slot
revenue for fiscal year 1997 of $312.4 million. The earnings before interest,
depreciation, amortization, management fees and bingo for the year ended
September 30, 1998 and for the period ended September 30, 1997 totaled
$200.2 million and $137.8 million, respectively. This represents a fiscal year
1998 operating margin of 34.8%
 
                                       8
<PAGE>
 
compared to a 29.6% operating margin in the period ended September 30, 1997.
Net loss for the year ended September 30, 1998 totaled $331.9 million, which
is primarily attributable to the relinquishment expense of $419.1 million
related to the Relinquishment Agreement with TCA. Under this Relinquishment
Agreement, the Authority has agreed to pay to TCA 5% of gross revenues, (as
defined in the agreement), generated from Mohegan Sun and a planned expansion,
beginning January 1, 2000 and ending December 31, 2014 (See Note 13 to the
Authority's Financial Statements). Net income for fiscal year 1997 was $36.7
million.
 
 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
 
  The growth in Connecticut gaming continues to expand as does Mohegan Sun's
share in this market. 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. Mohegan Sun exceeded the market's growth as it experienced a
26.8% increase in slot win over the prior year. Slot revenues of $396.3
million for the year ended September 30, 1998 reflected a slot win per unit
per day of $361. Slot win per unit per day for the period ended September 30,
1997 was $319. The slot win growth of $83.9 million or 26.8% over the previous
year reflected Mohegan Sun's growth in slot win market share of 2.8% over
prior year.
 
  Gaming revenues totaled $543.9 million for the 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 an
18.7% 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
908,821 and 587,952 as of September 30, 1998 and 1997, respectively.
 
  For the 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 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.
 
  Promotional allowances totaled $66.3 million for the year ended September
30, 1998, representing a $22.0 million or 49.7% increase over the prior 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 revenue increased
from 8.6% in fiscal 1997 to 10.3% in fiscal 1998.
 
  Total costs and expenses were $439.8 million for the year ended September
30, 1998, an increase of $52.0 million or 13.4% over the prior 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 the year, an increase of
$28.9 million or 13.8% over the prior year. The slot win contribution for the
year ended September 30, 1998 totaled $102.3 million. This represents an
increase of $21.6 million over the prior year, which is directly attributable
to increased slot revenues.
 
  General and administrative costs were $87.5 million for the 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 year increased by $5.4 million from the prior period.
 
 
                                       9
<PAGE>
 
  For the 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.
 
  Management fees earned by Trading Cove Associates totaled $47.4 million for
the year ended September 30, 1998, an increase of $24.2 million or 104.1%. The
increase in management fees are a direct result of the increase in operating
income.
 
  Income from operations for the 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.
 
  Interest and other income were $2.4 million for the year ended September 30,
1998, an increase of $604,000 or 33.6% over prior year.
 
  Interest expense of $50.2 million for the year ended September 30, 1998 was
an increase of $5.0 million or 11.2% over prior period interest. This increase
was mainly attributable to an increase in Cash Flow Participation Interest as
defined in the Senior Secured Notes due 2002, which is derived as a percent of
increased gross operating profits. Cash Flow Participation Interest is paid to
the holders of the Senior Secured Notes pursuant to the Senior Secured Note
indenture.
 
  Extraordinary items include loss on the early extinguishment of debt of
$332,000 due to the retirement of a capital lease and a $419.1 million
relinquishment expense associated with the Relinquishment Agreement. The
relinquishment expense is based upon the Authority's agreement to pay TCA 5%
of gross revenues (as defined in the 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 gross revenues by the Authority's risk free investment rate. See
Note 13 to the Authority's Financial Statements.
 
 Liquidity, Capital Resources and Capital Spending
 
  As of September 30, 1998 and 1997, the Authority held cash and cash
equivalents of $36.3 million and $40.4 million, respectively. Cash provided by
operating activities for 1998 was $134.6 million, compared with $117.2 million
for 1997.
 
  The Authority's capital spending has decreased slightly due to the 1997
capital lease obligations associated with the initial construction of the
property. Capital expenditures totaled approximately $32.7 million in 1998,
versus $35.7 million in 1997. Capital expenditures for furniture, fixtures and
equipment were $14.0 million in 1998 and $35.7 million in 1997.
 
  During the fiscal year, Mohegan Sun underwent a renovation of its north
entry of the casino and retail area. This $2.1 million project extended
Mohegan Sun's historical northeastern Indian theme in the depiction of a
stylized version of an ancient Mohegan Longhouse. The wooden panels depicting
old Indian tales, the ceiling of blankets, and the clay pipe decor enhance the
interior design of the casino which was inspired by Mohegan tradition and
culture. Renovations to the north entry totaled $1.7 million for the fiscal
year ended September 30, 1998 and were financed through internally generated
funds.
 
  In November 1998, the Authority introduced a $5.6 million race book facility
as an additional gaming amenity. This 9,000 square foot facility features
horse racing from the New York Racing Association circuit as well as greyhound
racing and jai alai from throughout the United States. The race book facility
features 230 seats with individual television monitors and computerized self-
service betting capabilities. For the fiscal year ended September 30, 1998,
expenditures associated with race book facility totaled $3.9 million.
 
 
                                      10
<PAGE>
 
  The Authority opened a 4,000 square foot gas station facility on December 7,
1998. 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 expenditures totaled $2.8
million during the fiscal year ended September 30, 1998. Both the gas station
and race book were financed through equipment leasing and internally generated
funds.
 
  During 1998, the Authority finalized contract negotiations with TCA for
Phase II at Mohegan Sun which is currently estimated to cost $750 million
(excluding capitalized interest and excluding a $50 million project
contingency). The proposed development plans include 100,000 square feet of
additional gaming space, a luxury hotel with approximately 1,500 rooms, and a
convention/events center with seating for 10,000 patrons and 100,000 square
feet of convention space. The Tribe also plans to include additional retail
and restaurant facilities into its design. Current plans would also require
significant upgrades and additions to the facility's parking and
infrastructure systems. The Tribe has chosen a site master planning firm, an
architect and a project developer for the expansion. These firms, in
conjunction with the Tribe, are in the process of developing a construction
schedule. As a result, the estimated project cost is still subject to
adjustment. Phase II is expected to break ground in the spring of 1999. Under
the Development Agreement, TCA 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, TCA will continue to manage
the existing property under the Management Agreement until December 31, 1999.
On January 1, 2000, the Management Agreement will terminate, and the Authority
will assume day-to-day management of Mohegan Sun. The Authority, as a result
of the termination of the Management Agreement, has agreed to pay to TCA 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 is estimated at $549.1 million as of
September 30, 1998 and will be reassessed periodically. The Authority has
capitalized $130 million of the relinquishment liability associated with
trademark value of the Mohegan Sun brand name.
 
  The Development Agreement was approved by the Bureau of Indian Affairs (the
"BIA") on February 7, 1998. The BIA determined on October 23, 1998 that the
Relinquishment Agreement did not require the approval of the BIA.
 
  For fiscal 1999, the Authority expects capital expenditures to be
approximately $16.3 million on facility improvements and $2.4 million on
existing construction projects. These expenditures exclude $3.1 million
relating to the completion of the gas station facility and preliminary
spending on the Phase II expansion.
 
  During fiscal 1998, the Authority, subsequent to meeting its operating
expenses and required deposits to reserve funds under the Indenture for the
Senior Secured Notes, distributed a total of $72.4 million to the Tribe. As
required under the Indenture for the Senior Secured Notes, the Authority made
an Excess Cash Purchase Offer of $29.1 million to all holders of the Senior
Secured Notes in January 1997. The holders of the Senior Secured Notes
rejected the offer which was subsequently offered to the holders of the
Authority's Junior Subordinated Notes. The holders of the Junior Subordinated
Notes also rejected the offer. The excess cash was distributed to the Tribe in
April 1998.
 
  On November 15, 1997 and May 15, 1998, the Authority made two interest
payments of $11.8 million each to the holders of the Senior Secured Notes and
payments of $4.1 million and $4.2 million in Cash Flow Participation Interest
on such dates to such debtholders. There are no cash interest payment
requirements on the Junior Subordinated Notes as interest is accrued and
deferred until a portion of the Senior Secured Notes are offered to be
repurchased or retired, as defined.
 
  Management believes that existing cash balances and operating cash flow will
provide the Authority with sufficient resources to meet its existing debt
obligations and foreseeable capital expenditure requirements with respect to
current operations for at least the next 12 months. The Authority has
commenced consideration of
 
                                      11
<PAGE>
 
expanded operations. (See "Part II--Item 7-Management's Discussion and
Analysis--"Liquidity, Capital Resources and Capital Spending.") Any such
expanded operations 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.
 
YEAR 2000 READINESS DISCLOSURE
 
 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 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 the business. Additionally, the Authority is dependent
upon many vendors to provide uninterrupted service for the operation to run
effectively. Exposure to both of these risk factors are issues the Authority
is currently addressing and is formulating an approach to handle these issues.
 
 Approach
 
  The Authority has developed a timeline to target issues within its own
operation as well as with suppliers. With the assistance of an outside
consultant, the Authority has implemented a Year 2000 program, which includes
inventorying its entities, identifying problems, planning and correcting the
problems, and testing the solutions.
 
 Status
 
  Through September 30, 1998, the Authority is approximately 40 percent
complete with its Year 2000 Program. The Authority anticipates completion of
the program by March 31, 1999. If at that time it is determined that the
project plan will not be completed, a contingency plan will be developed to
eliminate any disruption to operations.
 
 Cost
 
  The Authority has incurred approximately $25,000 in costs associated with
the Year 2000 Program as of September 30, 1998. 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.
 
REGULATION AND FEES
 
  The Mohegan Compact stipulates that a portion of the revenues earned on slot
machines must be paid to the State of Connecticut. This annual Slot Win
Contribution will 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.
 
  The Slot Win Contribution payments are linked to an exclusivity clause and
will terminate if the State legalizes other gaming operations (except those
consented to by the Tribe and/or the Pequot Tribe), 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
 
                                      12
<PAGE>
 
Contribution to the State of Connecticut for the year ended September 30,
1998, and the period ended September 30, 1997, respectively.
 
 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 in fiscal 1999. 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 in fiscal 1999. The Authority currently discloses
certain financial data by segment in the Statement of Operations as of
September 30, 1998 and 1997 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.
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 is required to be adopted in fiscal 2000, and does not expect
this statement 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 required to be adopted in fiscal 2000, and does not
expect this statement to have a material impact on the Authority's financial
position or results of operations.
 
CERTAIN FORWARD LOOKING STATEMENTS
 
  Certain information included in this Form 10-K and other materials filed or
to be filed by the Authority with the Securities and Exchange Commission
contains forward-looking statements, within the meaning of Section 27A of the
Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934.
Such statements include information relating to plans for future expansion and
other business development activities as well as other capital spending,
financing sources and the effects of regulation (including gaming and tax
regulation) and competition. Such forward-looking information involves
important risks and uncertainties that could significantly affect anticipated
results in the future and, accordingly, such results may differ from those
expressed in any forward-looking statements made by or on behalf of the
Authority. These risks and uncertainties include, but are not limited to,
those relating to development and construction activities, dependence on
existing management, leverage and debt service, domestic or global economic
conditions, issues related to the Year 2000, pending litigation, changes in
federal tax laws or the administration of such laws and changes in gaming laws

                   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 statement of cash flows for the years ended
September 30, 1998 and 1997. These financial statements and the schedule
referred to below are the responsibility of the Authority's management. Our
responsibility is to express an opinion on these financial statements and
schedule 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.
 
  Our audits were made for the purpose of forming an opinion on the basic
financial statements taken as a whole. The financial statement schedule listed
in Item 14 is the responsibility of the Authority's management and is
presented for purposes of complying with the Securities and Exchange
Commission's rules and is not part of the basic financial statements. This
schedule has been subjected to the auditing procedures applied in the audits
of the basic financial statements and, in our opinion, fairly states in all
material respects the financial data required to be set forth therein in
relation to the basic financial statements taken as a whole.

                         NOTES TO FINANCIAL STATEMENTS
 
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.
 
  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 things, that an
 
                                      F-7
<PAGE>
 
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:

 Advertising
 
  The Authority expenses the production costs of advertising the first time
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
contract following the month in which it appears.
 
 Trademarks
 
  Trademarks are amortized on a straight-line basis over the estimated periods
benefited, but not exceeding 40 years.
 
 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 it 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
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 Senior 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 Senior
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 Senior 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 Senior 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.

 Senior Secured Notes
 
  On September 29, 1995, the Authority issued $175 million in Senior Secured
Notes with fixed interest payable at a rate of 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 Authority's Cash Flow. Fixed
interest is payable semi-annually and commenced May 15, 1996. The aggregate
amount of Cash Flow Participation Interest payable will be reduced pro rata
for reductions in outstanding principal amount of Senior 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 to 1. 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 Senior Secured Notes
are redeemable at set prices as set forth in the Senior Secured Notes after
November 15, 1999, at the option of the Authority. Upon the occurrence of
certain events (as specified in the Senior Secured Notes) each holder of
Senior 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 Senior Secured Notes then outstanding, under
the Excess Cash Purchase Offer, as defined in the Senior 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 ("Subordinated
Notes"). The Authority has issued $20.0 million of Subordinated Notes to each
of Sun International and Waterford Gaming L.L.C., which notes bear interest at
 
                                     F-11
<PAGE>
 
15.0% per year. The Authority also has issued $50.0 million of Subordinated
Notes to Sun International evidencing draws made by the Authority under the
secured completion guarantee provided by Sun International ("Secured
Completion Guarantee"). Each Subordinated Note issued under the Secured
Completion Guarantee bears interest at the rate per annum then most recently
announced by Chase Manhattan Bank (f/r/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 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 Senior Secured Notes have been offered to be repurchased or retired,
pursuant to the terms of the Senior Secured Notes, and certain other
conditions have been fulfilled. Accrued and deferred interest payable on the
Subordinated Notes is $31.5 million and $17.9 million at September 30, 1998
and 1997, respectively. All Subordinated Notes are due 2003; however,
principal cannot be paid until the Senior Secured Notes have been paid in
full, unless certain conditions are met. During October 1998 and October 1997,
$2.5 million of 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 Senior Secured Notes reject all or any
portion of the Excess Cash Purchase Offer, as defined in the Indenture, the
Authority is required to offer to purchase, at par, certain amounts of the
Subordinated Notes then outstanding. See Excess Cash Purchase Offer below for
such offer made by the Authority.
 
 Excess Cash Purchase Offer
 
  Pursuant to the Senior Secured Notes, the Authority is required to make an
Excess Cash Purchase Offer to all holders of the Senior 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 Senior Secured Notes, the Authority
offered to purchase the Senior Secured Notes at 113.5% of the principal amount
of the Senior Secured Notes plus accrued and unpaid interest to the purchase
date. The Excess Cash Purchase Offer expired, by its terms, on February 25,
1998, and none of the holders of the Senior Secured Notes accepted the offer.
 
  On March 12, 1998, pursuant to the Subordinated Note purchase agreement, an
offer to repurchase in the amount of the Excess Cash Purchase Offer was made
to the holders of the Subordinated Notes. The offer period concluded on April
2, 1998, and the holders of the Subordinated Notes also rejected the offer. On
April 3, 1998, as permitted by Section 4.07(g) of the Senior 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 Senior Secured Notes within 120 days of September 30, 1998,
pursuant to the Senior Secured Notes. For the fiscal year ended September 30,
1998, it is estimated that this offer will be approximately $51.2 million.

NOTE 11--EMPLOYEE BENEFIT PLANS
 
  Effective February 10, 1997, the Authority adopted a retirement savings plan
for its employees under Section 401(k) of the Internal Revenue Code. The plan
allows employees of the 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 matches 50%
of eligible employees' contributions up to a maximum of 4% of their individual
earnings. The Authority recorded matching contributions of approximately $1.4
million and $792,000, respectively, to this plan for the year ended September
30, 1998 and the period ended September 30, 1997.
 
  Effective September 1, 1998, the Authority adopted the MTGA Non-Qualified
Deferred Compensation Plan. This plan allows highly compensated employees, as
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

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/or 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. At 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 Series B Senior Secured Notes
of the Authority in the original aggregate principal amount of $175 million
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 the Mohegan Sun resort 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. Payments
of 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 is 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 recognized the value of the trademarks
associated with the Mohegan Sun brand name as of September 30, 1998. The value
of the Mohegan Sun trademarks is $130 million. TCA's services will be retained
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 Senior Secured Notes and Subordinated Notes will be
refinanced. It is anticipated that a loss on the extinguishment of the Senior
Secured and Subordinated Notes will be reflected in the Authority's second
quarter financial statements for fiscal 1999.
 
  Effective January 1, 1999, the Authority changed 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(k)
of the Internal Revenue Code.

  of interest).
 
  6.2 Subordination of Relinquishment Payments. (a) TCA and the Authority
agree that each of the Junior Relinquishment Payments and each of the Senior
Relinquishment Payments are subordinated in right of payment, to the extent
and in the manner provided in this Section 6.2, to the prior payment of the
Minimum Priority Distribution (to the extent then due) and to the prior
payment of all Senior Secured Obligations (whether outstanding on the date
hereof or hereafter created, incurred, assumed or guaranteed), and that the
subordination referred to in this sentence is for the benefit of the Tribe and
the holders of Senior Secured Indebtedness. TCA and the Authority agree that
each of the Junior Relinquishment Payments (but not the Senior Relinquishment
Payments) are subordinated in right of payment, to the extent and in the
manner provided in this Section 6.2, to the prior payment of all Senior
Obligations (whether outstanding on the date hereof or hereafter created,
incurred, assumed or guaranteed), and that the subordination referred to in

or similar proceeding relating to the Authority or the business conducted in
the Facilities, or in an assignment for the benefit of creditors or any
marshaling of the Authority's assets and liabilities:
 
    (i) (A) the Tribe shall be entitled to receive the Minimum Priority
  Distributions then due in cash before TCA shall be entitled to receive any
  payment with respect to either the Senior Relinquishment Payments or the
  Junior Relinquishment Payments then due, (B) the holders of Senior Secured
  Indebtedness shall be entitled to receive payment in full in cash of all
  Senior Secured Obligations due in respect of such Senior Secured
  Indebtedness (including interest after the commencement of any such
  proceeding at the rate specified in the applicable Senior Secured
  Indebtedness) before TCA shall be entitled to receive any payment with
  respect to either the Senior Relinquishment Payments or the Junior
  Relinquishment Payments, and (C) the holders of Senior Obligations shall be
  entitled to receive payment in full in cash of such Senior Obligations
  (including interest after the commencement of any such proceeding at the
  rate specified in the document governing the applicable Senior Obligation)
  before TCA shall be entitled to receive any payment with respect to the
  Junior Relinquishment Payments; and
 
    (ii) (A) until all Minimum Priority Distributions then due are paid in
  full in cash, any payment or distribution in respect of any Relinquishment
  Payment to which TCA would be entitled but for the operation of this
  Section 6.2 shall be made to the Tribe, (B) if all Minimum Priority
  Distributions then due are paid in full in cash and until all Senior
  Secured Obligations (as provided in subsection (i) above) are paid in full
  in cash, any payment or distribution in respect of any Relinquishment
  Payment to which TCA would be entitled but for the operation of this
  Section 6.2 shall be made to holders of Senior Secured Indebtedness, as
  their interests may appear, and (C) if all Minimum Priority Distributions
  then due and Senior Secured Obligations are paid in full in cash and until
  all Senior Obligations (as provided in subsection (i) above) are paid in
  full in cash, any payment or distribution in respect of any Junior
  Relinquishment Payment to which TCA would be entitled but for the operation
  of this Section 6.2 shall be made to holders of Senior Obligations, as
  their interests may appear.
 
  (c) The Authority may not make any payment or distribution to TCA in respect
of any Relinquishment Payment and may not acquire from TCA any right to any
Relinquishment Payment or any release, satisfaction, discharge or
relinquishment of any Relinquishment Payment for cash or property until all
Minimum Priority Distributions then due have been paid in full in cash if a
default in the payment of any Minimum Priority Distribution then due has

  (d) Provided that provisions substantially equivalent to this Section 6.2(d)
prevent payments or distributions to or in respect of all Unsecured Senior
Refinancing Indebtedness, the Authority may not make any payment or
distribution to TCA in respect of any Relinquishment Payment and may not
acquire from TCA any right to any Relinquishment Payment or any release,
satisfaction, discharge or relinquishment of any Relinquishment Payment for
cash or property until all Senior Secured Obligations have been paid in full
if:
 
    (i) a default in the payment of any principal or other Obligations with
  respect to Designated Senior Secured Indebtedness occurs and is continuing
  beyond any applicable grace period in the agreement, indenture or other
  document governing such Designated Senior Secured Indebtedness; or
 
    (ii) a default, other than a payment default, on Designated Senior
  Secured Indebtedness occurs and is continuing that then permits holders of
  the Designated Senior Secured Indebtedness to accelerate its maturity and
  TCA receives a notice of the default (a "Payment Blockage Notice") from a
  Representative. If TCA receives any such Payment Blockage Notice, no
  subsequent Payment Blockage Notice shall be effective for purposes of this
  Section 6.2(d)(ii), irrespective of the number of defaults (other than
  defaults covered by clause (i) above) with respect to Designated Senior
  Secured Indebtedness during such period, unless and until at least three
  hundred sixty (360) days shall have elapsed since the effectiveness of the
  immediately prior Payment Blockage Notice issued under this Section
  6.2(d)(ii).
 
  (e) The Authority may not make any payment or distribution to TCA in respect
of any Junior Relinquishment Payment and may not acquire from TCA any right to
any Junior Relinquishment Payment or any release, satisfaction, discharge or
relinquishment of any Junior Relinquishment Payment for cash or property until
all Senior Obligations have been paid in full if:
 
    (i) a default in the payment of any amounts, principal or other
  Obligations with respect to Designated Senior Indebtedness or Senior
  Relinquishment Payments occurs and is continuing beyond any applicable
  grace period in the agreement, indenture or other document governing such
  Designated Senior Indebtedness or Senior Relinquishment Payments; 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 TCA receives
  a Payment Blockage Notice from a Representative. If TCA receives any such
  Payment Blockage Notice, no subsequent Payment Blockage Notice shall be
  effective for purposes of this Section 6.2(e)(ii), irrespective of the
  number of defaults (other than defaults covered by clause (i) above) with
  respect to Designated Senior Indebtedness during such period, unless and
  until at least three hundred sixty (360) days shall have elapsed since the
  effectiveness of the immediately prior Payment Blockage Notice issued under
  this Section 6.2(e)(ii).
 
  (f) The Authority may and shall resume payments on, and distributions in
respect of, any Relinquishment Payment (or portion thereof) the payment of
which was not permitted hereby, and the Authority may take actions with
respect thereto that were not permitted hereby, upon the earlier of:
 
    (i) the date upon which all applicable defaults that prevent such payment
  or distribution are cured or waived; or
 
    (ii) in the case of a default referred to in Section 6.2(d)(ii) or
  6.2(e)(ii) hereof, one hundred seventy nine (179) days following receipt of
  the applicable Payment Blockage Notice if the maturity of such Designated
  Senior Secured Indebtedness or Designated Senior Indebtedness, as
  applicable, has not been accelerated,
 
if this Section otherwise permits the payment or distribution or such action
at the time of such payment or distribution.
 
  (g) In the event that TCA receives any payment with respect to any
Relinquishment Payment at a time when TCA has actual knowledge that such
payment is prohibited by this Section 6.2, such payment shall be held by TCA,
in trust for the benefit of, and shall be paid over forthwith and delivered,
upon written request, to: (i) the
 
                                       9
<PAGE>
 
Tribe (to the extent that any Minimum Priority Distribution is then due and
not paid), (ii) the holders of Senior Secured Indebtedness (to the extent that
any such payment held by TCA was in respect of a Relinquishment Payment that
was subordinated to such Senior Secured Indebtedness), as their interests may
appear, or their Representative under the indenture or other agreement (if
any) pursuant to which Senior Secured Indebtedness may have been issued, as
their respective interests may appear, and (iii) the holders of Senior
Obligations (to the extent that any such payment held by TCA was in respect of
a Junior Relinquishment Payment that was subordinated to such Senior
Obligations), as their interests may appear, or their Representative under the
indenture or other agreement (if any) pursuant to which Senior Obligations may
have been issued or created, as their respective interests may appear, for
application to the payment, first to all Minimum Priority Distributions then
due and not paid, second, to all Senior Secured Obligations remaining unpaid
and then to all Senior Obligations remaining unpaid to the extent necessary to
pay such Senior Obligations in full in accordance with their terms, after
giving effect to any concurrent payment or distribution to or for the Tribe,
the holders of Senior Secured Indebtedness or the holders of Senior
Obligations or their Representatives, as the case may be.
 
  (h) The Authority shall promptly notify TCA of any facts known to the
Authority that would cause a payment of any portion of the Relinquishment
Payments to violate this Section, but failure to give such notice shall not
affect the subordination of the Relinquishment Payments as provided in this
Section.
 
  (i) After all Minimum Priority Distributions (to the extent then due) and
Senior Secured Obligations have been paid in full and until all Senior
Relinquishment Payments and all other Senior Indebtedness are current, TCA
shall be subrogated with respect to the Senior Relinquishment Payments
(equally and ratably with all other Senior Indebtedness pari passu with the
Senior Relinquishment Payments) to the rights of (i) the Tribe to receive
distributions applicable to Minimum Priority Distributions (to the extent then
due) to the extent that distributions otherwise payable with respect to the
Senior Relinquishment Payments have been applied to the payment of such
Minimum Priority Distributions, and (ii) holders of Senior Secured
Indebtedness to receive distributions applicable to Senior Secured Obligations
to the extent that distributions otherwise payable with respect to the Senior
Relinquishment Payments have been applied to the payment of Senior Secured
Obligations. A distribution made under this Section 6.2(i) to the Tribe or
holders of Senior Secured Indebtedness that otherwise would have been made in
respect of Senior Relinquishment Payments is not, as between the Authority and
TCA, a payment by the Authority in respect of Senior Relinquishment Payments.
 
  (j) After all Minimum Priority Distributions (to the extent then due),
Senior Indebtedness and Senior Relinquishment Payments have been paid in full
and until all Junior Relinquishment Payments are current, TCA shall be
subrogated with respect to the Junior Relinquishment Payments (equally and
ratably with all other Indebtedness pari passu with the Junior Relinquishment
Payments) to the rights of (i) the Tribe to receive distributions applicable
to Minimum Priority Distributions (to the extent then due) to the extent that
distributions otherwise payable with respect to the Junior Relinquishment
Payments have been applied to the payment of such Minimum Priority
Distributions, (ii) holders of Senior Secured Indebtedness to receive
distributions applicable to Senior Secured Indebtedness to the extent that
distributions otherwise payable with respect to the Junior Relinquishment
Payments have been applied to the payment of Senior Secured Indebtedness, and
(iii) holders of any other Senior Indebtedness to receive distributions
applicable to any other Senior Indebtedness to the extent that distributions
otherwise payable with respect to the Junior Relinquishment Payments have been
applied to the payment of such Senior Indebtedness. A distribution made under
this Section 6.2(j) to the Tribe, holders of Senior Secured Indebtedness or
holders of other Senior Indebtedness that otherwise would have been made in
respect of Junior Relinquishment Payments is not, as between the Authority and
TCA, a payment by the Authority in respect of Junior Relinquishment Payments.
 
  (k) This Section 6.2 defines the relative rights of TCA, the Tribe, holders
of Senior Secured Indebtedness and holders of Senior Obligations. Nothing in
this Section 6.2 shall:
 
    (i) affect the relative rights of TCA and creditors of the Authority
  other than their rights in relation to holders of Senior Secured
  Indebtedness, holders of Senior Obligations and the Tribe with respect to
  its rights to Minimum Priority Distributions;
 
                                      10
<PAGE>
 
    (ii) impair, as between the Authority and TCA, the obligation of the
  Authority, which is absolute and unconditional, to pay the Relinquishment
  Payments in accordance with the terms hereof; or
 
    (iii) prevent TCA from exercising its available remedies upon a default
  under this Relinquishment Agreement, including the right to obtain a
  judgment against the Authority for failure to pay any Relinquishment
  Payments when due pursuant to the provisions of Section 11 hereof, subject
  to the rights of holders of Senior Secured Indebtedness, holders of Senior
  Indebtedness and the Tribe to receive distributions and payments otherwise
  payable to TCA as or in respect of Relinquishment Payments.
 
  (l) No right of any holder of Senior Secured Indebtedness, any holder of
Senior Obligations or the Tribe to enforce the subordination provisions of
this Section 6.2 shall be impaired by any act or failure to act by the
Authority or TCA or by the failure of the Authority or TCA to comply with this
Section 6.2.
 
  (m) The Authority agrees and covenants that it will not, directly or
indirectly, create, incur, assume, guarantee, acquire, become liable,
contingently or otherwise, with respect to, or otherwise become responsible
for the payment of (collectively, "incur") any Indebtedness that by its terms
is expressly subordinated in right of payment to any obligation of the
Authority (other than any subordination in right of payment to the Minimum
Priority Distributions or to Senior Secured Indebtedness) unless (i) such
Indebtedness is subordinated at least to the same extent to the right of
payment to the Senior Relinquishment Payments and (ii) such Indebtedness is
expressly not Senior Indebtedness hereunder. The Authority shall not incur any
Indebtedness that by its terms is expressly subordinated in right of payment
to any obligations of the Authority (other than any subordination in right of
payment to the Minimum Priority Distributions or to Senior Secured
Indebtedness) and which subordination terms would permit any payment on the
obligations due thereunder at a time that obligations due with respect to the
Junior Relinquishment Payments would not be payable pursuant to the terms
hereof, unless such payment was pari passu or subordinated with the Junior
Relinquishment Payment (pro rata in accordance with the respective amounts
then due).
 
  (n) For the purposes of this Section 6.2, any Minimum Priority Distribution
shall be deemed paid for all purposes of this Section 6.2 if the Authority
lawfully may pay such Minimum Priority Distribution to the Tribe and has at
any time the funds lawfully available to pay such Minimum Priority
Distribution.
 
  (o) The provisions of this Section 6.2 shall not be amended or modified to
affect adversely (i) the holders of Senior Secured Indebtedness, with respect
to the provisions relating to Senior Secured Obligations, without the prior
written consent of the holders of all Designated Senior Secured Indebtedness;
provided, however, that a provision may be amended or modified with respect to
any class of Senior Secured Obligations to the extent such class has given its
prior written consent to such amendment or modification, (ii) the holders of
Senior Indebtedness, with respect to the provisions relating to Senior
Obligations, without the prior written consent of the holders of all
Designated Senior Indebtedness; provided, however, that a provision may be
amended or modified with respect to any class of Senior Obligations to the
extent such class has given its prior written consent to such amendment or
modification, and (ii) the Tribe, with respect to the provisions relating to
the Minimum Priority Distribution, without the prior written consent of the
Tribe.
 
  7. Certain Covenants of the Authority.
 
  7.1 Payments to the Tribe. Except for the payment of (a) the Minimum
Priority Distributions, or (b) reasonable charges for utilities or other
governmental services supplied by the Tribe and used by the Authority (in an
amount not to exceed the reasonable costs of such services plus a reasonable
allowance for administrative costs), the Authority shall not make any payment
or distribution to or for the benefit of the Tribe or any Affiliate of the
Tribe or make any distribution to the members of the Tribe (i) prior to the
payment in full of Relinquishment Payments then due, or (ii) at any time if
any Relinquishment Payments are outstanding.
 
  7.2 Affiliate Transactions. Except for the payment of (a) the Minimum
Priority Distributions, or (b) reasonable charges for utilities or other
governmental services supplied by the Tribe and used by the Authority (in an
amount not to exceed the reasonable costs of such services plus a reasonable
allowance for administrative

costs), the Authority shall not 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 any contract, agreement, understanding, loan, advance or
Guarantee with, or for the benefit of, the Tribe, an Affiliate of the Tribe or
an Affiliate of the Authority (each of the foregoing, an "Affiliate
Transaction"), unless (i) such Affiliate Transaction is on terms that are no
less favorable to the Authority than those that would have been obtained in a
comparable transaction by the Authority with an unrelated Person, and (ii) the
Authority delivers to TCA (a) with respect to any Affiliate Transaction
involving aggregate payments in excess of Two Million Dollars ($2,000,000), a
resolution adopted by a majority of the Management Board approving such
Affiliate Transaction and set forth in an Officer's Certificate certifying
that such Affiliate Transaction complies with clause (i) above and (b) with
respect to any Affiliate Transaction involving aggregate payments in excess of
Ten Million Dollars ($10,000,000), a written opinion as to the fairness to the
Authority from a financial point of view issued by an Independent Financial
Advisor.
 
  7.3 Subsidiaries. The Authority will not create, acquire or own any
instrumentality, subdivisions or subunits unless the actions and assets of
such instrumentalities, subdivisions or subunits are subject to or bound by
the terms of this Relinquishment Agreement.
 
  7.4 Business Purpose. During the Term, the Authority (or any assignee of the
Authority permitted under this Relinquishment Agreement), directly or
indirectly, shall not engage in any business or activity other than the
Principal Business.
 
  7.5 Operation of Casinos. During the Term, the Authority shall continue to
operate (i) the Mohegan Sun Casino for the primary purpose of conducting
Gaming, substantially in accordance with the standard and character of the
operations being conducted therein on the date hereof, and (ii) the New Casino
for the primary purpose of conducting Gaming, substantially in accordance with
the standard and character of the operations conducted therein one year after
the opening of the New Casino.
 
  7.6 Replacement or Restoration Following Casualty. If all or a portion of
the Facilities are damaged by fire or other casualty, the Authority promptly
shall cause the Facilities to be replaced or restored to substantially the
same condition as immediately prior to the occurrence of such fire or other
casualty; provided, however, that in no event shall the Authority be obligated
to expend for any replacement or restoration an amount in excess of the
insurance proceeds recovered by the Authority and allocable to the damage to
the Facilities after deduction of any amounts required to be paid to any
holder of Indebtedness. If insurance proceeds are not available to the
Authority for such replacement or restoration, the Authority shall use
reasonable efforts to obtain financing on commercially reasonable terms to
undertake such replacement or restoration of the Facilities.
 
  8. Marks. To the extent TCA has any rights to any of the Marks or the
"Mohegan Sun" name, TCA grants to the Authority an exclusive, irrevocable,
perpetual, world-wide, royalty free license to use the Marks and the "Mohegan
Sun" name in connection with the Facilities; provided, however, that the
Authority shall only use the word "Sun" in conjunction with the Facilities and
together with the word or words "Mohegan" or "the Mohegan Tribe" and that the
Authority will not use the word "Sun" separately as a trademark or servicemark
or engage in any activity that suggests it is affiliated with Sun
International or TCA after the Relinquishment Date. TCA acknowledges that all
of the Marks might not be used in connection with the Facilities, and the
Authority shall have sole discretion to determine which Marks shall be so
used. Except as may be required by law or to describe the historical
relationship between the parties, TCA shall not use the Authority's or the
Tribe's name, or any variation thereof, directly or indirectly, in any context
without the prior written approval of the Authority, which may be withheld in
its sole and absolute discretion.
 
  9. Non-Impairment of Agreement. The Tribe, directly or indirectly, shall not
impose any tax, levy or other monetary payment obligation on the Authority or
on any activity at the Facilities, other than (a) Minimum Priority
Distributions and (b) reasonable charges for utilities or other governmental
services supplied by the Tribe and used by the Authority (in an amount not to
exceed the reasonable costs of such services plus a reasonable allowance for
administrative costs). The Tribe shall not, directly or indirectly, take any
action, enter into any
 
                                      12
<PAGE>
 
agreement, amend its constitution or enact any ordinance, law, rule or
regulation that would prejudice or have a material adverse affect on the
rights of TCA under this Relinquishment Agreement. Neither the Tribe nor any
committee, agency, board or other official body of the Tribe shall, by
exercise of the police power, eminent domain or otherwise, act to modify,
amend or in any manner impair the obligations of the parties under this
Relinquishment Agreement without the written consent of TCA. Any such action
or attempted action shall be void ab initio. The Tribe acknowledges that the
MTC Court has the authority to provide equitable relief to enforce this
provision.
 
  10. Confidential and Proprietary Information. Each party agrees to treat as
confidential all non public information received during the performance of the
Gaming Management Agreement or pursuant to this Relinquishment Agreement
regarding the other party, its organization, financial matters, marketing
plans or other affairs. Except as may be required by law, no such information
will be disclosed to any person, firm or organization without the prior
written approval of the other party. Notwithstanding the provisions of Section
22 of the Gaming Management Agreement, the Authority may retain the
confidential and proprietary information developed by TCA and relating to the
management of the existing gaming and related operations pursuant to the
Gaming Management Agreement.
 
  11. Authority's Consent to Suit. The Authority expressly waives its immunity
from unconsented suit for the purpose of permitting a suit by TCA in any court
of competent jurisdiction, including, without limitation, the MTC Court, for
any claims by TCA for the purpose of enforcing this Relinquishment Agreement
and any judgment arising out of this Relinquishment Agreement. The Authority's
waiver of immunity from suit is specifically limited to the following actions
and judicial remedies: (a) the enforcement of the Authority's payment
obligations under this Relinquishment Agreement with an award of actual
damages in connection with any breach of the provisions hereof; provided,
however, that the court shall have no authority or jurisdiction to order
execution against any assets or revenues of the Authority except cash of the
Authority (except to the extent the Authority can demonstrate such cash was
derived from a source other than the Facilities) and undistributed and future
Revenues; and (b) an action to prohibit the Authority from taking an action
that would prevent the operation of this Relinquishment Agreement pursuant to
its terms, or that requires the Authority to specifically perform any
obligation under this Relinquishment Agreement. In no instance shall any
enforcement of any kind whatsoever be allowed against any assets of the
Authority other than the limited assets of the Authority specified in the
foregoing clause (a).
 
  12. No Liability of the Tribe; Limited Consent To Suit. Neither the Tribe
nor any director, officer or office holder, employee, agent, representative or
member of the Authority or the Tribe, as such, shall have any liability for
any obligations of the Authority under this Relinquishment Agreement or for
any claim based upon, in respect of, or by reason of such obligations or their
creation. The only assets subject to payment or encumbrances for the payment
of obligations hereunder shall be cash of the Authority (except to the extent
the Authority can demonstrate such cash was derived from a source other than
the Facilities) and the undistributed and future Revenues of the Authority.
Notwithstanding the foregoing, the Tribe expressly waives its immunity from
unconsented suit for the limited purpose of permitting a suit by TCA in any
court of competent jurisdiction, including, without limitation, the MTC Court,
for the sole purpose of obtaining equitable relief to enforce the provisions
of Sections 9, 12 and 13 of this Relinquishment Agreement. The Tribe's waiver
of immunity from suit is specifically limited to equitable relief to enforce
the provisions of Sections 9, 12 and 13; provided, however, that the court
shall have no authority or jurisdiction to order execution against any assets
or revenues of the Tribe and in no instance shall any enforcement of any kind
whatsoever be allowed against any assets of the Tribe.
 
  13. Government Savings Clause. This Relinquishment Agreement shall be
submitted to (a) the Bureau of Indian Affairs, and the National Indian Gaming
Commission, to the extent required by law, for appropriate action, if any, and
(b) the MTC Court for a stipulated declaratory judgment upholding its validity
and enforceability, the form of which will be mutually agreed to by the
Authority and TCA. In addition, each party agrees to pursue such actions or
judgment and execute, deliver and, if necessary, record any and all
instruments,
 
                                      13
<PAGE>
 
certifications, amendments, modifications and other documents as may be
required by the United States Department of the Interior, Bureau of Indian
Affairs, the office of the Field Solicitor, or any applicable statute, rule or
regulation or otherwise cooperate, as necessary, in order to effectuate,
complete, perfect, continue or preserve the respective rights, obligations and
interests of the parties to the fullest extent permitted by law; provided that
any such instrument, certification, amendment, modification or other document
shall not materially change the respective rights, remedies or obligations of
the parties under this Relinquishment Agreement or related agreements or
documents.
 
  14. Coordination. During the period of time between the Effective Date and
the Relinquishment Date, TCA and the Authority shall cooperate with each other
(at no cost to the other) as necessary to effect an orderly transition of the
operation of the existing gaming operations to the Authority.
 
  15. Employment Solicitation. From and after the date hereof until five (5)
years after the Relinquishment Date, neither TCA nor the Authority nor any
Affiliate of either party shall solicit, attempt to solicit or cause the
solicitation or attempted solicitation of any employee of TCA or the Authority
or any Affiliate of either party with whom TCA or the Authority or any
Affiliate of either party had contact, by virtue of their relationship
regarding the Facilities, to leave his or her employment and accept employment
with TCA or the Authority or any Affiliate of either party, as the case may
be.
 
  16. Miscellaneous Provisions.
 
  16.1 Authorization. The Authority and TCA represent and warrant to each
other that each has full power and authority to execute this Relinquishment
Agreement and to be bound by and perform the terms hereof. Each party shall
furnish evidence of such authority to the other. The Authority and TCA each
represent and warrant to the other that the execution, delivery and
performance of this Relinquishment Agreement shall not conflict with the terms
of their organizational documents, any agreement to which it is a party or by
which it is bound or any law, rule or regulation to which its subject.
 
  16.2 Relationship. From and after the Relinquishment Date, TCA shall not
have any management authority or responsibilities with respect to the

partners of each other by reason of this Relinquishment Agreement, and neither
shall have the power to bind or obligate the other.
 
  16.3 Governing Law. The rights and obligations of the parties and the
interpretation and performance of this Relinquishment Agreement shall be
governed by the law of the Tribe, and, to the extent not addressed by the law
of the Tribe, by applicable federal law, and, to the extent not addressed by
the law of the Tribe or applicable federal law, the law of the State of
Connecticut without regards to its principles regarding conflicts of law.
 
  16.4 Amendment. No modification or amendment to this Relinquishment
Agreement will be effective unless mutually agreed upon by both parties in
writing and unless such modification or amendment has received any required
regulatory approval.

  16.6 Third Party Beneficiary. This Relinquishment Agreement is exclusively

assigns of the parties pursuant to Section 16.7.
 
                                      15
<PAGE>
 
  16.7 Successors and Assigns. (a) The benefits and obligations of this
Relinquishment Agreement shall inure to and be binding upon the parties hereto
and their respective successors and assigns. Neither this Relinquishment
Agreement nor the rights hereunder may be assigned by TCA to any entity prior
to the Relinquishment Date. After the Relinquishment Date, neither this
Relinquishment Agreement nor the rights hereunder may be assigned by TCA to an
entity other than a Permitted Assignee, without the prior written consent of
the Authority (which may be withheld in its sole and absolute discretion) and
any required approvals by the Bureau of Indian Affairs or its authorized
representatives. Notwithstanding the foregoing, after the Relinquishment Date,
TCA or any Permitted Assignee may, without the consent of the Authority,
pledge its right to receive the Relinquishment Payments hereunder (but not
this Relinquishment Agreement itself) in connection with a bona fide
commercial financing from a financial institution, pension fund, insurance
company, pooled equity fund or other similar type of entity. In addition, on
or after December 31, 2001, TCA or its Permitted Assignees, if applicable (the
"Assignor"), may assign this Relinquishment Agreement or the rights hereunder
without the Authority's consent upon compliance with the following
requirements: (i) the Assignor shall promptly give the Authority written
notice of the terms and conditions of any proposed assignment (the "Assignment
Offer"), together with information regarding the proposed assignee and such
additional information as the Authority may reasonably request and (ii) the
Authority shall have fifteen (15) days after receipt of the Assignment Offer
to elect, by written notice delivered to Assignor within such fifteen (15) day
period to accept such Assignment Offer. If the Authority timely elects to
accept the Assignment Offer, the Authority shall have a period of sixty (60)
days following such election to close thereunder. If the Authority does not
timely elect to accept the Assignment Offer or thereafter fails to close
thereunder, then the Assignor may assign this Relinquishment Agreement for a
period of one hundred eighty (180) days thereafter to such third party in
accordance with the terms of the Assignment Offer.
 
  (b) The Authority may, without the consent of TCA, but subject to applicable
law, assign this Relinquishment Agreement to the Tribe, another
instrumentality of the Tribe or an entity wholly owned by the Tribe if such
assignee owns or conducts the business of the Facilities and is in compliance
with Section 7.4 on the date of such assignment. In the event of any such
permitted assignment, the assigning party shall be relieved of its obligations
under this Relinquishment Agreement which accrue from and after the date of
the assignment, provided that the assignee shall assume in writing the
obligations of the assignor under this Relinquishment Agreement and agree to
perform and be bound by the terms and provisions hereof effective from and
after the date of such assignment.
 
  16.8 Severability. The invalidity of any one or more provisions hereof or of
any other agreement or instrument given pursuant to or in connection with this
Relinquishment Agreement shall not affect the remaining portions of this
Relinquishment Agreement or any such other agreement or instrument or any part
thereof, all of which are inserted conditionally on their being held valid in
law; and in the event that one or more of the provisions contained herein or
therein should be invalid, or should operate to render this Relinquishment
Agreement or any such other agreement or instrument invalid, this
Relinquishment Agreement and such other agreements and instruments shall be
construed as if such invalid provision had not been inserted. Notwithstanding
the foregoing, the invalidity of any of Sections 2(a), 3 or 6.1 hereof shall
render the entire Relinquishment Agreement invalid.
 
  16.9 Entire Agreement. This Relinquishment Agreement (including any exhibits
referred to herein) represents the entire agreement between the parties hereto
with respect to the subject matter hereof. No other representations,
warranties, promises or agreements, express or implied, shall exist between
the parties unless such representations, warranties, promises or agreements
are in writing and bear a date subsequent to the date of this Relinquishment
Agreement.
 
  16.10 Headings. The headings used in this Relinquishment Agreement are for
the convenience of the parties only and shall not modify nor restrict any of
the terms or provisions hereof.
 
  16.11 Waivers. No failure or delay by TCA or the Authority to insist upon
the strict performance of any covenant, agreement, term or condition of this
Relinquishment Agreement, or to exercise any right or remedy consequent upon
the breach thereof, shall constitute a waiver of any such breach or any
subsequent breach of
 
                                      16
<PAGE>
 
such covenant, agreement, term or condition. No covenant, agreement, term or
condition of this Relinquishment Agreement and no breach thereof shall be
waived, altered or modified except by written instrument. No waiver of any
breach shall affect or alter this Relinquishment Agreement, but each and every
covenant, agreement, term and condition of this Relinquishment Agreement shall
continue in full force and effect with respect to any other then existing or
subsequent breach thereof.
 
  16.12 Periods of Time. Whenever any determination is to be made or action is
to be taken on a date specified in this Relinquishment Agreement, if such date
shall fall on a Saturday, Sunday or legal holiday under the laws of the State
of Connecticut or the Tribe, then in such event said date shall be extended to
the next day which is not a Saturday, Sunday or legal holiday.
 
  16.13 Consents and Approvals. Where approval or consent or other action of
the Authority, or any agent or political subdivision of the Authority, is
required, such approval shall mean the written approval of the Management
Board evidenced by a duly enacted resolution thereof, or, if not provided by
resolution of the Management Board, the written approval of such other person
or entity designated by resolution of the Management Board.
 
  16.14 Tolling of this Relinquishment Agreement. If any Tolling Event occurs,
the Authority shall give prompt notice thereof to TCA. If, within thirty (30)
days following receipt of such notice, TCA delivers written notice to the
Authority electing to implement this Section 16.14, then the Term shall be
tolled for such number of full calendar months commencing with the month
immediately following such Tolling Event and ending with (and including) the
calendar month immediately prior to the Recommencement Month (the "Tolling
Period"). The expiration of this Relinquishment Agreement (and the obligations
of the Authority to make payments of the Relinquishment Payments hereunder)
shall be extended for such number of full calendar months included in the
Tolling Period. During the Tolling Period, the Authority shall have no
obligation to make payments of any Relinquishment Payments.

provisions for the protection of the Authority that are deemed appropriate and
are requested by the Authority.

and/or the Cost Estimator, shall prepare "Schematic Design Documents"
consistent with industry standards which shall include, without limitation,
drawings and other documents illustrating the scale and relationship of the
proposed Project and the major divisions of each major element of the Project,
as well as a preliminary estimate of construction costs based upon the
proposed area, size and scope of each major element of the Project. The
Schematic Design Documents shall be submitted to the Authority for its review
and comment (consistent with the Project Program, the Project Schedule and the
Preliminary Budget) or approval, which approval shall not be withheld
unreasonably so long as such documents are consistent with the Project
Program, Project Schedule and Preliminary Budget.
 
  Upon final approval of the Schematic Design Drawings for the Project by the
Authority (but not before receipt of the Required Approvals and closing of the
Construction Financing), the Architect, under the direction of Developer and
in consultation with the Construction Manager, shall prepare "Design
Development Documents" for the Project consistent with industry standards
which shall include, without limitation, drawings and other documents to fix
and describe the size and character of each major element of the Project as to
architectural, structural, mechanical and electrical systems, materials and
such other elements as may be appropriate. Further, the Architect,
Construction Manager and/or the Cost Estimator shall advise Developer and,
subject to the requirements of Section 4.4 above, update the Preliminary
Budget to the extent necessary. Following completion of any revisions which
Developer deems necessary to the Design Development Documents, Developer shall
submit copies thereof to the Authority, together with any necessary updates to
the Preliminary Budget (subject to the requirement of Section 4.4 above), for
the Authority's review and comment (consistent with the Project Program, the
Project Schedule, the Project Budget and the Schematic Design Documents) or
approval, which approval shall not be withheld unreasonably so long as the
Design Development Documents are consistent with the Project Program, Project
Schedule and approved Schematic Design Documents.

  4.6 Construction Documents. Based upon, and consistent with, the Project
Schedule, approved Design Development Documents and Preliminary Budget, the
Architect shall prepare for Developer's approval, full construction documents
(the "Plans and Specifications") prepared so as to conform to all Legal
Requirements and to allow bids to be obtained on the work described therein.
The Plans and Specifications shall be consistent with industry standards and
shall include, without limitation, all architectural, mechanical, electrical
and plumbing drawings and specifications necessary to complete the
construction of the Project. In addition, subject to the requirements of
Section 4.4 above, the Architect and Construction Manager shall advise
Developer and update the Preliminary Budget to the extent necessary based upon
the Plans and Specifications. Following completion of any revisions which
Developer deems necessary to the Plans and Specifications, Developer shall
submit the Plans and Specifications, together with any necessary updates to
the Preliminary Budget, to the Authority for its review and approval, which
approval shall not be withheld unreasonably so long as the Plans and
Specifications are consistent with the Project Program, Project Schedule and
approved Design Development Documents.
 
  4.7 Compliance with Construction Standards, Environmental Laws and
Regulations. The Project shall be designed and constructed so as to protect
the environment and the public heath and safety, as agreed upon by Developer
and the Authority. The design, construction and maintenance of the Project
shall, except to the extent waived in writing by the Authority, meet or exceed
all established standards pertaining to the Tribe or all building codes, fire
codes and safety and traffic requirements (but excluding planning, zoning and
land use laws, ordinances, regulations and requirements) which would be
imposed on the Project by existing local, state or federal laws or regulations
which would be applicable if the Project were located outside of the
jurisdictional boundaries of the Tribe, even though those requirements may not
apply within the Tribe's jurisdictional boundaries. Nothing in this
Development Agreement shall grant to the State of Connecticut or any political
subdivision thereof any jurisdiction (including but not limited to
jurisdiction regarding zoning or land use) over the Property or the design,
construction, equipping and opening of the Project.
 
  4.8 Suspension of Obligations. On the earlier of (a) the date on which the
NIGC or the Bureau of Indian Affairs gives notice to Developer, the Tribe or
the Authority that the Required Approvals with respect to the Relinquishment
Agreement dated February 7, 1998 between the Authority and Trading Cove
Associates (the "Relinquishment Agreement") or this Development Agreement in
their current forms (including any changes mutually acceptable to the parties)
will not be granted or (b) the earlier of (i) six (6) months after the date of
execution of this Development Agreement or (ii) the date that the Schematic
Design Drawings are approved, if no response has been received from the NIGC
or the Bureau of Indian Affairs with respect to the Required Approvals of the
Relinquishment Agreement or this Development Agreement in their current forms
(including any changes mutually acceptable to the parties), Developer shall
not be authorized or required to provide any further services under this
Development Agreement, and all work relating to the development of the Project
shall cease, and shall not recommence until forms of the Relinquishment
Agreement and this Development Agreement agreeable to the Authority and
Developer have received the Required Approvals.

                          Construction of the Project
 
  5.1 Employment of Contractors. Within thirty (30) days of the Authority's
approval of the Design Development Documents, the Construction Manager, under
the direction of Developer, shall begin to prequalify (in accordance with
criteria approved by the Authority) and interview contractors with significant
experience in the construction of comparable hotel, resort, convention and
gaming facilities in the region where the Property is located based upon the
need for such contractors as provided in the Project Schedule. Thereafter, as
may be required by the Project Schedule, the Construction Manager, under the
direction of Developer, shall prepare detailed bid packages based upon the
Plans and Specifications, which shall include, without limitation, the
Construction Manager's standard form agreement prepared under the direction of
Developer and approved by the Authority, and all necessary performance
specifications developed by or for Developer, with the assistance of the
Construction Manager (the "Bid Packages"). The Bid Packages shall be subject
to the Authority's prior
 
                                      B-8
<PAGE>
 
written approval, in its sole and absolute discretion. The Bid Packages shall
be sent to at least three (3) pre-approved contractors. Any bids not returned
within the bidding period set forth in the Bid Packages shall be disregarded
unless the Authority elects to extend the bidding period. Developer shall
advise the Authority Representative concerning the status of, and the
Authority may, at its option, participate in, the bidding processes. Based on
the results of the bidding process and subject to compliance with the
requirement set forth in Section 8.1 that preference be given to Certified
Entities, Developer shall recommend the selection and employment by the
Authority of the contractors to construct and equip the Project, which
recommendation shall be subject to the approval of the Authority, in its sole
and absolute discretion. The approved contractors shall be referred to herein
as the "Contractors." Each of the Contractors shall be properly licensed as
required by applicable law and, if required by the Authority, shall furnish a
payment and performance bond or other guaranty of performance reasonably
satisfactory to the Authority, to cover the construction and equipping of the
Project. Neither Developer nor any Affiliate of Developer shall be eligible to
serve or be employed as a Contractor.
 
  5.2 Contract Documents. Subject to the Authority's final approval and its
right to participate in negotiations, Construction Manager, under the
direction of Developer, shall be responsible for preparing and negotiating a
contract and other contract documents with the Contractors. The contract and
other contract documents with the Contractors (the "Contract Documents") shall
require the Contractors to construct and equip the Project in accordance with
the directives of the Construction Manager, the approved Plans and
Specifications and their approved bids and to be responsible for providing all
surety, administrative and other services, materials, equipment and labor
defined in the Contract Documents. The Contract Documents shall contain such
provisions for the protection of the Authority that are reasonably deemed
appropriate and are requested by the Authority and provide for insurance,
appropriate lien waivers and for construction schedules which include progress
payments and may include liquidated damages for delayed performance.
 
  5.3 Final Budget. Within thirty (30) days following approval of the Design
Development Documents and commencement of preparation of the Plans and
Specifications, Developer, in consultation with the Architect, Construction
Manager and/or Cost Estimator shall prepare a proposed final budget for the
Project, which shall contain all costs related to the design, construction and
equipping of the Project, plus a contingency of ten percent (10%) of the hard
construction costs (the "Proposed Final Budget"). If the Proposed Final Budget
exceeds Total Project Costs, then Developer and the Authority shall work
together to either revise the Design Development Documents and/or the Plans
and Specifications as agreed, or revise the ceiling on Total Project Costs, as
determined in the Authority's sole and absolute discretion. Within fifteen
(15) days of submission thereof, the Authority shall either approve or comment
upon the Proposed Final Budget, which approval may be withheld in the
Authority's sole and absolute discretion. Developer shall modify the Proposed
Final Budget as required to conform to the Authority's comments and shall
resubmit it for final approval within fifteen (15) days (or such additional
time as the extent of the comments reasonably require) following receipt of
the Authority's comments. The approved budget shall be the "Final Budget."
Subject to the approval requirements set forth below, Developer may, after at
least fifteen (15) days prior written notice to the Authority (which shall
include an explanation): (i) revise the line items in the Final Budget from
time-to-time as necessary to reflect any unforeseen changes, variables or
events or to include additional, unanticipated items of expense, (ii)
reallocate part or all of the amount budgeted with respect to any line item to
another line item, and (iii) to make such other modifications to the Final
Budget, as Developer deems necessary. Any allocation of the contingency
contained in the Final Budget shall require the approval of the Authority. In
addition, the Authority shall receive written notices of all change orders,
and any change orders in excess of (x) Seven Hundred Fifty Thousand Dollars
($750,000) in any single instance, (y) Three Million Dollars ($3,000,000) in
the aggregate in any one month or, (z) Twelve Million Dollars ($12,000,000) in
the aggregate over the duration of the Project, shall, at the Authority's
option, require the prior written approval of the Authority (which may be
withheld in its sole and absolute discretion).
 
  5.4 Supervision of the Contractor and Construction. The Construction
Manager, under the direction of Developer, shall supervise the Contractors
engaged to perform services in connection with the construction of the
Project. All Contractors shall be selected and employed in compliance with
Section 8.1 of this Development Agreement. The Construction Manager, under the
direction of Developer, shall be responsible for the
 
                                      B-9
<PAGE>
 
supervision, review and administration of any and all Contract Documents or
invoices during the construction and close-out of the Project. Unless
otherwise provided in this Development Agreement, Developer shall have full
power and authority to act on behalf of the Authority in connection with any
Contract Documents which have been approved by the Authority; provided,
however, that Developer shall not have any authority to declare a default or
exercise remedies under any Contract Documents without the Authority's prior
written approval, which may be withheld in its sole and absolute discretion.
 
  Developer and/or the Construction Manager, shall have control of and charge
and responsibility for, supervision of any Persons performing work on the
Property in connection with the Project. The Construction Manager, under the
direction of Developer and subject to review by the Architect, shall cause the
Contractors to construct the Project in accordance with the Plans or
Specifications and other requirements of the Contract Documents, including,
without limitation, any changes or modifications thereto approved by the
Authority, and shall not authorize the Contractors to pay or incur any
obligations not approved by the Authority (to the extent such approval is
required hereunder). Developer, in consultation with the Architect, the
Construction Manager and the Authority's Representative, shall review
applications for payment for submission to the Authority and review and
certify the amounts due. In addition, Developer, in consultation with the
Authority's Representative, shall supervise and assist the Architect and the
Construction Manager in: (a) interpreting and deciding matters concerning the
performance of any Contractor and the requirements of the Contract Documents;
(b) observing and evaluating the work performed and rejecting work which does
not conform to construction contracts and related documents; (c) using
reasonable efforts to cause the Contractors to pay punctually all sums due for
labor, materials, fixtures or equipment used or purchased in connection with
the construction of the Project; and (d) inspecting the work to determine the
dates of temporary occupancy, partial, substantial and final Completion of the
Project (which must be agreed to by the Architect and the Authority).
 
  5.5 Late Payment Fees; Bonus; Delay Claims. The Authority and Developer
agree that time is of the essence in completing the Project and, together with
the Construction Manager, they may seek to include in certain material
Contract Documents, certain provisions that if a Contractor fails to meet
project schedules, the Contract Documents shall provide that such Contractor
shall pay to the Authority an amount to be determined by Developer and the
Authority for each calendar day that it fails to meet such project schedules,
as liquidated damages and not a penalty. In addition, subject to the approval
of the Authority (which may not be unreasonably withheld), the Contract
Documents may include a bonus payment if a Contractor completes its work on
the Project prior to the deadline therefor.

               Selection of Equipment, Furniture and Furnishings
 
  Subject to the Final Budget for the Project, Developer shall, through itself
or a purchasing agent retained by the Authority, arrange for the selection of
vendors and suppliers for purchase by the Authority of equipment, furniture
and furnishings required to operate the Project. Alternatively, at the
Authority's option, Developer shall arrange for the procurement of equipment,
furniture and furnishings on lease terms approved by the Authority. All
vendors and suppliers shall be selected and employed in compliance with
Section 8.1 below. Developer shall be responsible for the negotiation,
preparation, supervision, review and administration of any and all contracts,
agreements or invoices with vendors and suppliers, and, unless otherwise
provided in this Development Agreement, Developer, consistent with the terms
of the Final Budget, shall have full power and authority to act on behalf of
the Authority in connection with any contracts which have been approved by the
Authority with vendors and suppliers. Notwithstanding the foregoing, with
respect to any such contract in excess of Seven Hundred Fifty Thousand Dollars
($750,000), Developer shall not terminate such contract or exercise other
remedies with respect thereto without the Authority's prior written consent,
which may be withheld in its sole and absolute discretion.

                      Funding Requirements of the Project
 
  7.1 Tribe's Funding Obligations. Developer agrees to cooperate fully with
the Authority in the Authority's efforts to arrange the Construction
Financing. The Authority shall, prior to commencement of construction of the
Project, make available or otherwise cause to be established a development
fund into which shall be deposited all of the proceeds of the Construction
Financing. Said funds shall be designated exclusively for performing the
Authority's obligations under any agreements entered into with respect to the
management, supervision, design, construction, equipping and opening of the
Project. The funds procured under the Construction Financing shall be used to
discharge the Authority's obligations under any and all agreements entered
into for the management, supervision, design, construction, equipping and
opening of the Project, including, without limitation, consulting fees,
professional fees, on-site and off-site improvements, architectural,
engineering, contractors' fees and costs, furniture, signs, trade fixtures and
equipment necessary for implementing the operation of the Project, closing and
financing related costs, and interest as provided under the Construction
Financing.
 
  7.2 Deadline for Construction Financing. Notwithstanding any contrary
provision contained herein, if the Authority fails to obtain Construction
Financing on or before December 1, 1998, the Authority shall provide Developer
with written notice that the Construction Financing has not been obtained,
together with written notice either, at its sole option that (a) the Authority
has elected to proceed with the design, construction, equipping and opening of
the Project based upon alternative financing arrangements or (b) the Project
has been suspended. Upon any such election to suspend the Project, the
Authority shall pay all amounts due to the Architect, the Construction Manager
or other Contractors for the period prior to the date of such suspension and
shall pay to Developer its reasonable out of pocket expenses directly related
to the Project Executive and the services provided in connection with the
performance of its duties hereunder prior to the date of such suspension. If
the Authority elects to proceed with the Project, the Authority shall provide
Developer with proof of alternative financing, whereupon Developer shall
proceed with its obligations pursuant to this Development Agreement. If the
Authority elects to suspend the Project, Developer shall suspend its services
under this Development Agreement pending receipt from the Authority of a
notice to proceed. If the Authority subsequently obtains financing for the
Project, the parties' obligations under this Development Agreement shall be
reinstated.

                      Additional Duties, Obligations and
                            Authority of Developer
 
  8.1 Approval of Contractors, Vendors and Suppliers. Upon notice to the
Authority, Developer shall be responsible for determining the acceptability of
Contractors, vendors and suppliers proposed by the Architect and the
Construction Manager; provided, however, that if any Contractor, vendor or
supplier is to perform work with respect to the Project, including, without
limitation, performing labor or other services or delivering or installing any
materials, goods, equipment, furniture or furnishings, for an amount greater
than Seven Hundred Fifty Thousand Dollars ($750,000), the selection of such
Contractor, vendor or supplier must be approved in writing by the Authority.
In order to maximize the benefits of the Project to the Tribe and the
Authority, Developer shall implement procedures described in the Tribal
Employment Rights Ordinance or otherwise developed by the Authority so that
preference be given in the recruiting, prequalification, negotiation and
selection of the Architect and the Construction Manager and all Contractors,
vendors and suppliers to business entities or persons which have been approved
by the Authority (the "Certified Entities") in all employment categories
relating to the design, construction, equipping and opening of the Project. If
there are Certified Entities that are experienced in the relevant employment
category, the opportunity to compete for employment in such employment
category shall be made available to such Certified Entities. Only in the event
that the bids by such Certified Entities are unreasonable based on
commercially competitive standards or that the Certified Entities lack the
capability to complete the contract, shall the bidding with respect to such
employment category be reopened to entities or persons that are not Certified
Entities. If Developer or the Construction Manager
 
                                     B-11
<PAGE>
 
determines that a Certified Entity lacks the capability to complete a
contract, Developer shall so notify the Authority at least five (5) days
before bidding therefor is opened to entities or persons that are not
Certified Entities, and Developer and the Construction Manager shall require
that the Certified Entities be considered as a subcontractor with respect to
portions of such contract for which they are qualified.
 
  8.2 Employment of Other Professionals. The Authority, in consultation with
Developer, shall select and employ other professionals, including, without
limitation, surveyors, attorneys, accountants and public relations or
advertising firms, to perform services required for the Project.
 
  8.3 Expenditures. Subject to variances and change orders specifically
permitted hereunder, Developer shall not authorize any expenditure of funds
other than expenditures authorized by the Authority as set forth in the
Preliminary Budget (as modified from time to time in accordance with the terms
hereof) or the Final Budget for the Project (as modified from time to time in
accordance with the terms hereof).
 
  8.4 Progress Reports and Meetings. The Authority, the Project Executive and
the Construction Manager shall have weekly meetings (and other meetings as may
be needed) to discuss the progress of the Project. In addition, on a monthly
basis, the Executive Project Committee shall meet to discuss all issues with
respect to the Project, including, without limitation, updates to the Project
Schedule and Preliminary or Final Budget (as applicable), any claims or
disputes, the status of the work and all other relevant items. Prior to such
monthly meetings, Developer shall submit to the Authority monthly progress
reports showing the then present status of design and/or construction of the
Project. If the progress reports reflect a substantial deviation from the
budget or design or construction progress schedules approved by the Authority,
Developer shall submit to the Authority with Developer's design or
construction report an explanation thereof and proposed corrective steps, as
applicable.
 
  8.5 Submission of Contracts. Developer agrees promptly to submit to the
Authority copies of all contracts and subcontracts relating to the Project
from time to time received by Developer and all other documents related to the
Project. Developer, with the assistance of the Construction Manager, shall
assist the Authority in complying with the terms of and maintain in full force
all contracts for design or construction of the Project and any surety bonds
issued in connection therewith. Developer shall give the Authority immediate
notice of any known failure of any party to comply with the terms of any such
contract or bonds and shall submit to the Authority copies of any
correspondence regarding an alleged default by any person in relation to any
contract or agreement relating to the Project, together with an explanation
thereof and proposed corrective steps.
 
  8.6 Permits and Licenses. Except for permitting and licensing requirements
of the Tribe, Developer shall advise the Authority as to all permitting and
licensing requirements for the Project, and the Authority, in consultation
with Developer, shall obtain or cause to be obtained all permits and licenses
required for the design, construction equipping and opening of the Project.
 
  8.7 Maintenance of Records. Developer, the Construction Manager and the
Architect, shall maintain on the Property all books and records in connection
with the design, construction, equipping and opening of the Project, together
with all documents and papers pertaining to the Project, including, without
limitation, general maintenance of such full and detailed accounts as may be
necessary for proper financial management of the Project. All such documents
shall at all times be open to the inspection of the Authority. Copies of such
documents shall be provided to the Authority or the Authority's
Representative, and Developer shall cooperate with any audit of such books and
records. After the expiration or termination of this Development Agreement,
Developer shall deliver all such books and records together with all such
related documents and papers to the Authority, and Developer shall be entitled
to retain a copy.
 
  8.8 Staffing of Project. (a) Developer shall have the responsibility and
authority to direct the selection, retention and training of all initial
employees performing regular services in connection with the management,
operation and maintenance of the Project on the Completion Date. No later than
sixty (60) days prior to the anticipated Completion Date of the Project (or
any portion thereof that will be opened for business), Developer
 
                                     B-12
<PAGE>
 
shall submit to the Authority, for its approval, a detailed staffing plan for
all personnel necessary to operate the Project (or portion thereof) in a first
class manner, which staffing plan shall include, without limitation,
organizational charts, a job classification system with job descriptions,
salary levels and wage scales (the "Staffing Plan"). The Staffing Plan shall
be subject to the Authority's review and approval (which approval may be
withheld in its sole and absolute discretion) and to compliance with the
Tribal Employment Rights Ordinance.
 
  (b) All prospective employees shall be subject to the Authority's approval,
which approval, with respect to Key Personnel, may be withheld in the
Authority's sole and absolute discretion. All Key Personnel and any and all
other employees as required by the Director of Regulation of the Authority
shall be subject to background checks to be performed by the Authority (and
the Authority shall have the right to reject any candidate for any position
based on the results thereof). In order to maximize the benefits of the
Project to the Tribe and the Authority, in accordance with the Tribal
Employment Rights Ordinance, Developer shall give preference in employment and
training for Key Personnel positions to qualified candidates recommended by
the Authority. In addition, in accordance with the Tribal Employment Rights
Ordinance, Developer shall give preference in recruiting, training and
employment by the Authority for all positions to qualified members of the
Tribe and their spouses and children in all job categories of the Project,
including, without limitation, management positions. Only if no tribal
members, spouses or children are qualified for a particular job opening may
other candidates be considered. Thereafter, preference shall be given to
qualified, enrolled members of other federally recognized Indian tribes.
Developer shall supervise all activities determined necessary by the Authority
to recruit and train Tribe members, spouses and children, including, without
limitation, providing job fairs for members of the Tribe and clearly
specifying in all job advertisements the preference for Tribe members.
 
  (c) Notwithstanding anything contained herein to the contrary, from and
after the Completion Date of the Project (or any portion thereof which is
sooner opened for business), all decisions with respect to the management,
operation and maintenance of the Project (or portion thereof) shall be made
exclusively by the Authority.
 
  8.9 Force Majeure Events. Notwithstanding anything in this Development
Agreement to the contrary, the parties hereto shall be excused from their
obligations hereunder to the extent and for so long as such party shall be
prevented from compliance by reason of "Force Majeure Causes", provided notice
of such inability to comply is given to the other party to this Development
Agreement within ten (10) days after the occurrence of the applicable Force
Majeure Cause.

  The Authority shall pay to Developer as compensation for the services set
forth herein, a fee in the amount of Fourteen Million Dollars ($14,000,000)
(the "Development Fee"). The Development Fee shall be paid as follows: on
January 15, 2000 and thereafter within fifteen (15) days following the end of
each calendar quarter until the Completion Date, the Authority shall pay to
Developer a percentage of the Development Fee equal to the completion
percentage of the Project certified by Developer as of December 31, 1999 and
the end of each successive calendar quarter. The Authority shall make payments
of the Development Fee to Developer upon receipt of an application for payment
from Developer, which statement shall include evidence of satisfaction of the
foregoing conditions to payment.

  Subject to Section 12.5 below, this Development Agreement may only be
terminated by the Authority or Developer if the other party commits any
material breach or fails to perform any material duty or obligation of this
Development Agreement. Upon learning of a material breach or default, the non-
breaching party shall send written notice of such material breach or default
to the breaching party. Subject to Section 12.5 below, if the breaching party
fails to cure the material breach or default within thirty (30) days of
receipt of such written notice from the non-breaching party, the non-breaching
party may terminate this Development Agreement by providing the defaulting
party with a notice of termination (which shall be immediately effective).

                              Dispute Resolution
 
  12.1 Authority's Consent to Suit. Subject to Section 12.5 below, the
Authority expressly waives its immunity from unconsented suit for the purpose
of permitting or compelling arbitration as provided in this Article 12, and to
be sued in any court of competent jurisdiction for any claims by Developer for
the purpose of compelling arbitration or enforcing any arbitration award or
judgment arising out of this Development Agreement. In no instance shall any
enforcement of any kind whatsoever be allowed against any assets of the
Authority other than the limited assets of the Authority specified in Section
12.4.
 
  12.2 Arbitration. All disputes controversies or claims arising out of or
relating to this Development Agreement, or the termination of this Development
Agreement, shall be settled by binding arbitration in accordance with the
commercial arbitration rules of the American Arbitration Association and the
Federal Arbitration Act. The parties agree that binding arbitration shall be
the sole remedy as to all disputes arising out this Development Agreement,
unless the parties mutually agree otherwise. The arbitrator(s) shall have no
authority to award punitive damages and the parties and the arbitrator(s)
shall maintain strict confidentiality with respect to the arbitration. In
determining any matter, the arbitrator(s) shall apply the terms of this
Development Agreement, including, without limitation, Section 12.5, without
adding to, modifying or changing the terms in any respect, and shall apply the
laws of the Tribe. All arbitration hearings shall be held at a place
designated by the arbitrator(s) in New London County, Connecticut.
 
  12.3 Limitation of Actions. The Authority's waiver of immunity from
unconsented suit is specifically limited to the following actions and judicial
remedies: (i) the enforcement of an award of actual damages by arbitration
subject to Section 12.4; provided, however, that the arbitrator(s) and/or the
court shall have no authority or jurisdiction to order execution against any
assets or revenues of the Authority except undistributed or future revenues of
the Project and the existing Mohegan Sun casino; (ii) the enforcement of a
determination by an arbitrator that prohibits the Authority from taking an
action that would prevent Developer from performing this Development Agreement
pursuant to its terms, or that requires the Authority to specifically perform
any obligation under this Development Agreement; (iii) an action to compel
arbitration pursuant to Section 12.2; and (iv) an action to preserve the
status quo during disputes pursuant to Section 12.5.

nor any director, officer or office holder, employee, agent, representative or
member of the Authority or the Tribe, as such, shall have any liability for
any obligations of the Authority under this Development Agreement or for any

Development Agreement and such other agreements and instruments shall be
construed as if such invalid provision had not been inserted).

covenant, agreement, term or condition of this Development Agreement and no
breach thereof shall be waived, altered or modified except by written
instrument. No waiver of any breach shall affect or alter this Development

Board evidenced by a duly enacted resolution thereof, or, if not provided by

Representative (to the extent authorized by the Management Board) or such
other person or entity designated by resolution of the Management Board. If
the approval of Developer or the Authority is required hereunder, Developer or
the Authority, as the case may be, shall request such approval in writing,

necessary), in writing, from such other party within fifteen (15) days

related to the Project.
 
  13.17 Non-Impairment of Agreement. The Tribe shall not take any action,
enter into any agreement, amend its constitution or enact any ordinance, law,
rule or regulation that would prejudice or have a material adverse affect on
the rights of Developer under this Development Agreement. Neither the Tribe
nor any committee, agency, board or other official body of the Tribe shall, by

action or attempted action shall be void ab initio. The Tribe acknowledges
that the MTC Court has the authority to provide equitable relief to enforce

                           INTRODUCTION TO YOUR PLAN

Your Employer has instituted this Plan to reward efforts made by Employees who
contribute to the overall success of the Company. The Plan is exclusively for
the benefit of Participants and their Beneficiaries. The purpose of the Plan is
to help you build financial security for your retirement and to help protect you
and your Beneficiaries in the event of your death or Disability.

This Plan is a 401(k) plan. It offers you a built in savings system through
pre-tax payroll deductions. It also offers attractive tax advantages, the
freedom to choose investments according to your needs, the flexibility to change
your investments as your needs change, and a way to build capital for a secure
retirement.

Under the terms of this Plan, you may choose to defer a portion of your current
salary, which your Employer then contributes to the plan on a pre-tax basis.
Contributions are not subject to Federal income tax, and in most cases are also
exempt from state or local income taxes. Since your contributions are not
subject to Federal income tax, your taxable income is reduced.

The laws governing plans like this one contain many provisions that may affect
your retirement. You should contact your Plan Administrator with any questions
about the Plan before you make any decisions related to your retirement. For
specific tax advice, you should contact your tax advisor.

This Summary Plan Description (SPD) summarizes the key features of your Plan,
and your rights, obligations and benefits under the Plan. Some of the statements
made in this SPD are dependent upon this Plan being "qualified", or approved by
the Internal Revenue Service. Please contact your Plan Administrator with any
questions you may have after you have read this summary.

Every effort has been made to make this description as accurate as possible.
However, this booklet is not a Plan document. This SPD is not meant to
interpret, extend, or change the provisions of the Plan in any way. The terms of
the Plan are stated in and will be governed in every respect by the Plan
document. Your right to any benefit depends on the actual facts and the terms
and conditions of the Plan document, and no rights accrue by reason of any
statement in this summary. A copy of the Plan document is available at the
principal office of your Employer for inspection. You, your Beneficiaries, or
your legal representatives may request to inspect the Plan Document at any
reasonable time.

LOAN AVAILABILITY:                 An active Participant in the Plan may request
                                   a loan from the Plan. A loan allows you to
                                   borrow money from your account without
                                   incurring a penalty. You must repay the loan
                                   with interest, on an after tax basis, usually
                                   through payroll deduction.

                                   Once you request a loan, your Employer is
                                   required to approve the loan. After approval,
                                   you will receive a check with an attached
                                   promissory note. By endorsing the check, you
                                   agree to the terms and repayment conditions
                                   in the promissory note.

                                   As an active Participant in the Plan, you may
                                   request a loan from


LOAN REQUIREMENTS:                 1. Loans are available to all participants
                                   in the Plan on a uniform and
                                   nondiscriminatory basis.

                                   2. Loans must bear a reasonable rate of
                                   interest.

                                   If you are married at the time of your death,
                                   your surviving spouse is your Beneficiary
                                   unless:

                                   .  You elect otherwise in writing (with the
                                      consent of your spouse); 
                                   .  You establish to the satisfaction of the

                                   than your spouse, (an "alternate

                                   provided by the Plan Administrator. You may
                                   revoke or change this designation at any time
                                   by filing written notice with the Plan
                                   Administrator, however, your spouse must
                                   consent, in writing, to any alternate
                                   Beneficiary. Your spouse's consent must be
                                   witnessed by a Notary Public or Plan
                                   official.

                                   It is important that you notify the Plan
                                   Administrator of any change in your marital
                                   status.

LOAN LIMITATIONS:                  You may borrow any amount up to 50% of your
                                   vested account balance. However, your loan
                                   can be no more than $50,000 minus your
                                   highest outstanding loan amount during the

                                      was available,

                                   .  Payment may be made in installments
                                      payable in cash or in kind, or part in
                                      cash and part in kind over a period not to
                                      exceed your lifetime, or the joint
                                      lifetime of you and your spouse,

                                   .  If your Beneficiary is your spouse,

                                      31st of the calendar year in which you

elected. In any case, payments will continue to be made at least as rapidly as
such payment were being made prior to your death.

                                   If you fail to designate an alternate

                                   less, death benefits will be distributed to
                                   your Beneficiary without your Beneficiary's
                                   consent as soon as practicable following your

                                   An optional form of payment with respect to
                                   your vested account balance is installments

                                   and part in kind over a period not to exceed
                                   your lifetime, or the joint lifetime of you
                                   and your spouse.

                                   If you transferred money from a prior plan,
                                   another form of benefit may be available. You
                                   should consult with your tax advisor
                                   regarding those options.

You may request that all or part of any taxable distribution you receive from
the Plan, other than an annuity, installments paid over 10 or more years, or
required distributions after age 70 1/2, be rolled over directly from the
Trustees to the trustee or custodian of an eligible retirement plan. For this
purpose, an "eligible retirement plan" includes an individual retirement account
of annuity, or your new employer's qualified plan, if the plan accepts
rollovers. The Plan Administrator will notify you if any amount to be
distributed to you is an eligible rollover distribution. Special tax withholding
rules apply to any portion of the eligible rollover distribution which is not
rolled over directly to an eligible retirement plan.

TOP HEAVY DEFINED:                 A plan becomes Top-Heavy when 60% or more of
                                   the Plan's assets are allocated to Key
                                   Employees. Key Employees are certain owners
                                   or officers of your Employer. If the Plan
                                   becomes Top Heavy certain rules apply

TOP HEAVY RULES:                   A minimum contribution will be required to
                                   non key employees. This contribution is the
                                   lesser of:

                                   .  three percent (3%) of Compensation; or 
                                   .  the largest percentage of Compensation
                                      contributed by the Employer on behalf of
                                      key employees.
                                   .  If you are a Participant in more than one
                                      Plan maintained by your Employer, you may
                                      not be entitled to minimum benefits in
                                      more than one plan.

                                      whether a rollover or transfer is
                                      acceptable;

                                   .  You may make such a contribution to this
                                      Plan prior to being eligible for the Plan;

                                   .  Any amount rolled over or transferred to
                                      this Plan cannot include personal IRA
                                      contributions;

                                   .  Prior to making a rollover or transfer,
                                      you should consult with your tax advisor.

                              will not be considered to have a Period of
                              Severance if you return to work immediately upon
                              the expiration of such leave of absence. If you
                              are on a leave of absence because of maternity or
                              paternity, the second anniversary of the first
                              date of your leave, if you remain absent from
                              service with your Employer. For example, if you
                              went on maternity leave on October 1, 1995, you
                              would not be considered to have severed service
                              with your Employer if you returned to work and
                              performed an Hour of Service before October 1,
                              1997. If you did not return to work on or before
                              October 1, 1997, you would incur a Period of
                              Severance.

                              If you are reemployed after you incur a Period of
                              Severance and you were vested when you terminated
                              employment, upon your reemployment, you will be
                              immediately eligible for the Plan, and you will be
                              vested at the same percentage as when you left.

                              If you are reemployed after you incur a Period of
                              Severance and you were not vested when you
                              terminated employment, you will lose credit for
                              service you completed prior to your termination if
                              your absence is five years or longer.

                              If you are reemployed within five years after you
                              incur a Period of Severance, and you received a
                              full or partial distribution (including a "deemed"
                              distribution if you had a $0 account balance), you
                              may return as a Participant at the same vested
                              percentage as when you left, provided you repay
                              the amount distributed to you within five years of
                              the date you are reemployed. After repayment, your
                              account balance will be restored to its original
                              amount as though there had been no distribution,
                              and any amount forfeited when you left will be
                              replaced by your Employer.

                              If you are reemployed after you incur a five-year
                              Period of Severance, you will not be given the
                              opportunity to repay the

                                      amount distributed to you and your vested
                                      percentage will be determined based on
                                      your Years of Service beginning on your
                                      date of reemployment.

                                      If you terminate service prior to becoming
                                      a Participant in the Plan, you will be
                                      treated as a new employee upon your
                                      reemployment. To participate, you must
                                      meet the Eligibility Requirements.

QUALIFIED DOMESTIC RELATIONS ORDERS:  As a general rule, your account balance,
                                      may not be assigned. This means that your
                                      accounts cannot be sold, used as
                                      collateral for a loan, given away, or
                                      otherwise transferred. In addition, your
                                      creditors may not attach, garnish or
                                      otherwise interfere with your account.

                                      An exception to this general rule is a
                                      "qualified domestic relations order" or
                                      QDRO. A QDRO is a court order that can
                                      require the plan administrator to pay a
                                      portion of your account balance to your
                                      former spouse, child or other dependent.

PLAN AMENDMENT OR TERMINATION:        Your Employer reserves the right to amend
                                      the Plan at any time. However, no
                                      amendment can deprive you of any vested
                                      benefits.

                                      Your Employer also reserves the right to
                                      terminate the Plan. If the Plan is
                                      terminated, you will be 100% vested in
                                      your total account balance under the Plan.


                           STATEMENT OF ERISA RIGHTS


As a Participant in the Plan, you are entitled to certain rights and protection
under the Employee Retirement Income Security Act of 1974 (ERISA). Your Employer
may not fire you or discriminate against you to prevent you from obtaining a
benefit from the Plan or exercising your rights under ERISA.

ERISA provides that all Plan Participants shall be entitled to:

 .  Examine, without charge, at your Plan Administrator's office, all Plan
   documents, insurance contracts, if any, and copies of all documents filed by
   your Plan with the U. S. Department of Labor, such as annual reports and Plan
   descriptions.

 .  Obtain copies of all Plan documents and other Plan information upon written
   request to your Plan Administrator. Your Plan Administrator may impose a
   reasonable charge for the copies.

 .  Receive a summary of the Plan's annual financial report. Your Plan
   Administrator is required by law to provide each Participant with a copy of
   the Plan's Summary Annual Report.

 .  Obtain an annual statement telling you whether you have a right to receive a
   benefit under the Plan, and if so, what your benefits would be if you stop
   working for your Employer now. If you do not have a right to a benefit under
   the Plan, the statement must tell you how many years you have to work to get
   a benefit under the Plan. The Plan may require a written request for this
   statement, but it must be provided free of charge.

                                      13
<PAGE>
 
 .   File suit in Federal court if any materials requested are not received
    within 30 days of your request unless the materials were not sent because of
    matters beyond the control of your Plan Administrator. The court may require
    your Plan Administrator to pay you up to $100 per day for each day's delay
    until the materials are received by you.

In addition to creating rights for Plan participants, ERISA imposes obligations
upon the persons who are responsible for the operation of the Plan. These
persons are referred to as "fiduciaries". Fiduciaries must act solely in the
interest of Plan participants and must exercise prudence in the performance of
their plan duties. Fiduciaries who do not comply with ERISA may be removed and
required to make good any losses they have caused the Plan.

If Plan fiduciaries are misusing the Plan's assets, as a Participant in the
Plan, you have the right to file suite in a Federal court or to request
assistance from the U.S. Department of Labor. If you are successful in your
lawsuit, the court may require the other party to pay your legal costs,
including attorney's fees. If you are unsuccessful in your lawsuit, or the court
finds your action frivolous, the court may order you to pay these costs and
fees.


                               CLAIMS PROCEDURES


When you terminate employment, you must complete a form that notifies the Plan
Administrator that you are making a claim for benefits. Your Employer has a
supply of these forms. Ideally this form should be completed on or before your
final day of work. This way, your Employer can send your claim for benefits
right away for processing.

If, after your claim for benefits is processed, you have questions or disagree
with the calculation of your benefit, you must notify the Plan Administrator in
writing. The Plan Administrator will, within 90 days(or within 180 days if
special circumstances exist) notify you in writing of its decision. That
notification will include:

1.  How your benefit was calculated,
2.  The specific reason that your claim is denied (in whole or in part) if it is
    denied 
3.  Specific references to Plan provisions on which the denial is based 
4.  A description of any additional material or information necessary for you to
    perfect your claim and an explanation of why such information is necessary
5.  An explanation of the Plan's claim review procedure.

Within 60 days after you receive notice of the denial of part or all of your
claim for benefits, you may file a written appeal with the Plan Administrator.
You may seek representation by an attorney or other representation of your
choosing. You may submit written and oral evidence and arguments in support of
your claim. You may review all relevant documents. The Plan Administrator
generally makes a final decision within 60 days of your appeal. The Plan
Administrator decision will include the specific reasons for its decision and
specific references to Plan provisions on which the decision is based
