NOTE 1 - BACKGROUND INFORMATION AND BASIS OF PRESENTATION

Background Information

     Coast Hotels and Casinos, Inc. ("The Company"), a Nevada corporation, is a
wholly owned subsidiary of Coast Resorts, Inc. ("Coast Resorts"), which is also
a Nevada corporation.  The Company owns and operates the following Las Vegas
hotel-casinos:

 .  Gold Coast Hotel and Casino, approximately one mile west of the Las Vegas
   Strip on Flamingo Road.
 .  Barbary Coast Hotel and Casino, located on the Las Vegas Strip.
 .  The Orleans Hotel and Casino, located approximately one mile west of the Las
   Vegas Strip on Tropicana Avenue.

     The Gold Coast and Barbary Coast hotel-casinos had, prior to January 1996,
been owned and operated independently by two partnerships, Gold Coast Hotel and
Casino, a Nevada limited partnership, and Barbary Coast Hotel and Casino, a
Nevada general partnership (collectively, the "Predecessor Partnerships").  On
January 1, 1996, the partners of the Predecessor Partnerships completed a
reorganization (the "Reorganization") with Coast Resorts.  Coast Resorts was
formed in September 1995 for the purpose of effecting such Reorganization of the
Predecessor Partnerships.  Coast Resorts, Gold Coast and Barbary Coast were all
related through common ownership and management control.

     In the Reorganization, the partners of the Predecessor Partnerships each
transferred to Coast Resorts their respective partnership interests in the
Predecessor Partnerships in exchange for an aggregate of 1,000,000 shares of
common stock, par value $.01 per share, of Coast Resorts ("Coast Resorts Common
Stock").  Coast Resorts immediately contributed to the Company all of the assets
and liabilities of the Predecessor Partnerships other than those relating to the
Coast West Lease (as defined herein),  which Coast Resorts contributed to its
wholly owned subsidiary, Coast West, Inc. ("Coast West").  The Coast West Lease
is a long-term lease on approximately 50 acres of land in Las Vegas on which the
Company may develop and operate a future hotel-casino.  Coast Resorts retained
the liability for an aggregate principal amount of $51.0 million in notes
payable to former partners and retained the liability for $1.5 million relating
to demand notes due to a related party (the "Exchange Liabilities").  On January
16, 1996, the Exchange Liabilities were exchanged for 494,353 shares of Coast
Resorts Common Stock, based upon management's estimate of the fair market value
of such Coast Resorts Common Stock.

Basis of Presentation

     The accompanying financial statements are unaudited and have been prepared
in accordance with generally accepted accounting principles for interim
financial information and with Article 10 of Regulation S-X.  Accordingly, they
do not include all of the information and footnotes required by generally
accepted accounting principles for complete financial statements.  The unaudited
financial statements should be read in conjunction with the audited financial
statements and footnotes for the year ended December 31, 1997.  In the opinion
of management, all adjustments and normal recurring accruals considered
necessary for a fair presentation of the results for the interim period have
been included.  The interim results reflected in the unaudited financial
statements are not necessarily indicative of expected results for the full year.

Reclassifications

       Certain amounts in the 1997 financial statements have been reclassified
to conform with the 1998 presentation.

NOTE 2-ADVANCES TO COAST WEST

     The Company has agreed to provide advances to Coast West sufficient to make
payments on the Coast West Lease and other obligations, including project
development and site improvement. The Coast West Lease relates to a parcel of
land located in the western area of Las Vegas to be used for future expansion
opportunities. The Coast West Lease term runs through December 31, 2055, with
three 10-year renewal options, with monthly payments of $166,667 for the year
ending December 31, 1995. Thereafter the monthly rent increases by the amount of
$5,000 in January of each year. The lease includes a put option exercisable by
the landlord requiring the purchase of the land at fair market value at the end
of the 20th through 24th years of the lease, provided that the purchase price
shall not be less than ten times, nor more than fifteen times, the annual rent
at such time. Based on the terms of the lease, the potential purchase price
commitment ranges from approximately $31,000,000 to approximately $51,000,000 in
the years 2014 through 2018. The advances to Coast West are non-interest bearing
and, pursuant to the indenture governing 13% first mortgage notes issued by the
Company (the "Indenture"), cannot exceed $8.0 million in aggregate principal
amount at any time outstanding unless Coast West becomes a subsidiary of the
Company.  As of June 30, 1998 and December 31, 1997,  the Company had advanced
Coast West $7.7 million and $6.4 million, respectively, related to the Coast
West Lease and development activities. Coast West is a development stage
enterprise and has no source of income and is therefore solely dependent on the
advances to be provided by the Company. There can be no assurance that Coast
West will develop a gaming property at the Coast West site or that it will be
able to repay any advances made by the Company.  Management believes that the
advances related to the capital improvements at the Coast West site have an
asset value that could be transferred to and used by the Company should Coast
West fail to develop the project.  Therefore, the Company has only recorded an
allowance for doubtful accounts in an amount equal to advances provided for
lease payments.

     On July 21, 1998, Coast Resorts contributed the capital stock of Coast West
to the Company, as a result of which Coast West became a wholly owned subsidiary
of the Company. Coast West remains a guarantor of the 13% First Mortgage Notes.
Pursuant to the terms of the Indenture, the Company may continue to make
advances to Coast West as it is now a wholly owned subsidiary.

     performance, or as alternatives to cash provided by operating activities as
     an indicator of cash flows or a measure of liquidity. EBITDA and EBITDAR
     are presented solely as supplemental disclosure because management believes
     that they are widely used measures of financial performance in the gaming

ITEM 2.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATION (CONTINUED)

Three Months Ended June 30, 1998 Compared to Three Months Ended June 30, 1997
and Six Months ended June 30, 1998 Compared to Six Months Ended June 30, 1997

     Net revenues, operating income and net income all improved in the quarter
ended and six months ended June 30, 1998, primarily due to improved revenues at
the Company's newest hotel-casino, The Orleans.   Net revenues in the quarter
ended June 30, 1998 were $80.0 million compared to $72.3 million in the same
quarter of 1997, an increase of 10.6%.  For the six months ended June 30, 1998,
net revenues were $161.0 million compared to $144.7 million in the same period
in 1997.  Operating income in the second quarter of 1998 was $9.8 million
compared to $4.4 million in the second quarter of 1997, an increase of 126.0%.
For the six months ended June 30, 1998, operating income was $20.9 million, an
increase of 182.3% over operating income of $7.4 million in the same period in
1997.  Net income in the quarter ended June 30, 1998 was $2.3 million compared
to a net loss of $2.0 million in the second quarter of 1997.  For the six months
ended June 30, 1998, net income was $5.1 million compared to a net loss of $3.6
million in 1997.

     The Orleans. The Orleans opened in December 1996 and generated lower-than-
expected revenues in the first half of 1997.  During the second half of 1997,
the property expanded its customer base through increased promotional
activities, the use of headliner entertainment in its showroom and, in December
1997, the opening of twelve new movie theaters.  Net revenues in the three
months ended June 30, 1998 were $38.1 million, an increase of 23.9% over
revenues of $30.7 million in the same quarter in 1997.  For the six month period
ended June 30, 1998, net revenues were $76.2 million, an increase of 31.1%
compared to the first six months of 1997.  Casino revenues were up in the second
quarter of 1998 (25.1%) and in the six months ended June 30, 1998 (35.0%),
primarily as a result of increased slot machine activity.  Increased customer
volume led to an increase in food and beverage revenues of 27.4% in the quarter
ended June 30, 1998 and an increase of 23.9% in the six months ended June 30,
1998.  Hotel revenues increased slightly in the quarter and year-to-date,
primarily as a result of increased occupancy.  Other revenues increased in the
second quarter and year-to-date due primarily to higher showroom revenue.
Despite an increase in operating expenses of 13.8% in the quarter ended June 30,
1998 and 10.5% for the six months ended June 30, 1998, due primarily to
increased casino promotional activities, operating income increased by $3.3
million in the quarter and by $11.8 million year-to-date.

     Gold Coast.  Net revenues in the three months and six months ended June 30,
1998 were relatively flat compared to the same periods in 1997, with slight
increases in casino revenues and slight decreases in hotel, food and beverage
and other revenues. For the quarter ended June 30, 1998, net revenues were $31.0
million, down 1.3% from second quarter 1997 revenues of $31.4 million. Year-to-
date, net revenues were $63.5 million, down 0.8% compared to $64.0 million in
the first six months of 1997. Operating income in the second quarter of 1998 was
$6.4 million, an increase of 11.9% over the second quarter of 1997. Operating
income in the first six months of 1998 was $13.0 million, an increase of 8.3%
over the first six months of 1997. The increases were due primarily to lower
payroll expenses as a result of reduced staffing.

     Barbary Coast. Net revenues in the three months ended June 30, 1998
increased 7.1% to $10.9 million compared to $10.2 million in the three months
ended June 30, 1997,  primarily as a result of increased customer wagering on
slot machines.  Additionally, table games revenues were up because of improved
win percentages compared to the same quarter in 1997.  Increases in slot machine
and table games revenues were partially offset by decreases in race book
revenues due to lower win percentages.  For the six months ended June 30, 1998,
net revenues were $21.4 million, down $1.3 million (5.7%) compared to the same
period in 1997 primarily due to a lower-than-expected table games win percentage

in the first quarter of 1998 as well as a lower win percentage in the race book.
For the second quarter, operating income was $631,000 compared to a loss of
$898,000 in the second quarter of 1997.  For the six months ended June 30, 1998,
operating income was $694,000 compared to an operating loss of $79,000 in the
same period in 1997.  Operating expenses declined $808,000 (7.3%) and $2.1
million (9.1%) in the three month and six month periods ended June 30, 1998,
respectively, compared to the same periods in 1997, primarily due to decreased
promotional expenses in the race book.

LIQUIDITY AND CAPITAL RESOURCES

     The Company's principal sources of liquidity have consisted of cash
provided by operating activities, bank financing and debt financing.  Cash
provided by operating activities was $13.9 million in the first six months of
1998, an increase of $16.0 million over the same period in 1997, primarily due
to the Company's increased profitability discussed above.

     In January 1996, the Company issued $175.0 million principal amount of 13%
first mortgage notes due 2002 ("13% First Mortgage Notes").  Additionally, in
November 1997, the Company issued $16.8 million principal amount of 10 7/8%
first mortgage notes due 2001 ("10 7/8% First Mortgage Notes").  The indentures
pursuant to which the 13% First Mortgage Notes and the 10 7/8% First Mortgage
Notes were issued ("the Indentures") contain covenants that, among other things,
limit the ability of the Company to pay dividends or make advances to Coast
Resorts, repay existing indebtedness, incur additional indebtedness, or sell
material assets as defined in the Indentures.

     The Company's cash requirements, in addition to interest on the 10 7/8%
First Mortgage Notes, the 13% First Mortgage Notes and equipment notes payable,
which is anticipated to be approximately $27.0 million in 1998, include annual
principal payments of approximately $7.5 million on the equipment notes payable,
land lease payments for its properties, ongoing maintenance capital expenditures
at its existing facilities and periodic enhancements to those facilities.  The
Company's maintenance capital expenditures for 1997 were approximately $9.2
million. Management expects that maintenance capital expenditures for 1998 will
be approximately $9.5 million. Management believes that existing cash balances
and operating cash flow will provide the Company with sufficient resources to
meet its existing debt obligations, lease payments and foreseeable capital
expenditure requirements at the Company's existing properties.

     The Company agreed to provide advances to Coast West sufficient to make
payments on the Coast West Lease and other obligations, including project
development and site improvement.  Pursuant to the Indenture under which the 13%
First Mortgage Notes were issued, the advances to Coast West could not exceed
$8.0 million in aggregate principal amount at any time outstanding.  As of June
30, 1998, the Company had advanced Coast West $7.7 million related to the Coast
West Lease and development activities.  Based on the cash requirements of Coast
West for lease payments and anticipated development costs, it is likely that
during 1998 Coast West would require cash from the Company that, when added to
the outstanding advances from the Company, would exceed $8 million. On July 21,
1998, Coast Resorts contributed the capital stock of Coast West to the Company,
as a result of which Coast West became a wholly owned subsidiary of the Company.
Coast West remains a guarantor of the 13% First Mortgage Notes.  Pursuant to the
terms of the Indenture, the Company may make advances to its wholly owned
subsidiaries.

ITEM 2.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATION (CONTINUED)

     The Company has no agreements, arrangements or understandings with respect
to financing the development of future properties.  Any future development would
be subject to, among other things, the Company's ability to obtain necessary
financing.

IMPACT OF THE YEAR 2000 ISSUE

     The "Year 2000 Issue" is the result of computer programs being written
using two digits rather than four to define the applicable year.  If a company's
date-sensitive computer programs should recognize a date "00" as the year 1900
rather than the year 2000, miscalculations or a system failure could occur,
causing disruptions of operations, including, among other things, a temporary
inability to process transactions, send invoices or engage in similar normal
business activities.

     The Company is currently reviewing all of its computer systems with regard
to the Year 2000 Issue and has determined that much of its software is already
compliant.  For those systems not already compliant, the Company will utilize
both internal and external resources to reprogram, replace and test the software
for the Year 2000 modifications so that its computer systems will properly
recognize and utilize dates beyond December 31, 1999. Management believes that
expenditures for these modifications will not be material.  However, the Company
may be adversely affected to the extent that vendors and other entities with
which it does business are unable to achieve Year 2000 compliance by December
31, 1999.

ACCOUNTING PRONOUNCEMENTS

     In June 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 130, "Reporting Comprehensive Income" ("SFAS
130"), which establishes standards for reporting and display of comprehensive
income and its components.  SFAS 130 requires a separate statement to report
components of comprehensive income for each period presented.  The provisions of
SFAS 130 are effective for fiscal years beginning after December 15, 1997.
Management believes that the Company currently does not have items that would
require presentation in a separate statement of comprehensive income.

     In June 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 131, "Disclosures about Segments of an
Enterprise and Related Information" ("SFAS 131"), which supersedes FASB
Statement No. 14, "Financial Reporting for Segments of a Business Enterprise."
SFAS 131 establishes standards for the way that public business enterprises
report information about operating segments in annual financial statements and
requires that those enterprises report selected information about operating
segments in interim financial reports issued to shareholders.  SFAS 131 is
effective for fiscal years beginning after December 15, 1997 and requires
restatement of earlier periods presented.  SFAS 131 will not have a material
effect on the Company's financial statements as the required information is
either currently being presented by the Company or it is not applicable to the
Company.

     In April 1998, the American Institute of Certified Public Accountants
issued Statement of Position 98-5 (SOP 98-5), Reporting on the Costs of Start-Up
Activities.  SOP 98-5 requires that the Company expense its pre-opening and
related promotional expense as incurred rather than capitalize it

                                       10
<PAGE>
 
and amortize it over the estimated period of economic benefit of such costs as
has been the Company's policy in the past.  Effective January 1, 1998, the
Company adopted SOP 98-5. The adoption had no impact on the financial position,
results of operations or cash flows of the Company as all start-up costs
previously capitalized had been expensed in prior periods.
