Incorporated, Goldstrike Investments, Incorporated, Diamond Gold, Inc., Gold
Strike Aviation, Incorporated, Goldstrike Finance Company, Inc., Oasis
Development Company, Inc., Michael S. Ensign, the Reporting Person, David R.
Belding, Peter A. Simon II and Robert J. Verchota, as amended (the "Merger

the Issuer his indirect interests in (i) three operating and licensed Nevada
casinos, (ii) two gasoline service stations, holding restricted gaming licenses,
(iii) an Illinois-licensed riverboat gaming facility, and (iv) various
development properties located in Nevada, Indiana/Kentucky, and Mississippi
(collectively, the "Gold Strike Properties"). In return, the Issuer agreed to
issue 6,457,807 Shares, and distribute $4,762,650 in cash, to the Reporting
Person. After the parties to the Merger Agreement obtained the requisite gaming
and other governmental approvals and bank consents, the transactions
contemplated by the Merger Agreement were effected (the "Closing") on June 1,
1995 (the "Closing Date"), resulting in, among other things, the transfer by the
Reporting Person of his indirect interests in the Gold Strike Properties to
certain subsidiaries of the Issuer and the issuance and distribution by the
Issuer of 6,457,807 Shares (the "Original Shares") and $4,762,650 in cash to the

an exercise price of $13.00 per share by the exercise of an employee stock
option granted by the Issuer on February 9, 1999 (the "February 1999 Option").
The February 1999 Option, which expires on February 9, 2009, became exercisable
as to 333,333 Shares on February 9, 2000 and February 9, 2001, respectively, and
became exercisable as to the remaining 333,334 Shares on February 9, 2002.  The
Shares beneficially owned by the Reporting Person as of the date hereof also
include 333,333 shares which the Reporting Person is entitled to purchase at an
exercise price of $20.20 per share by the exercise of an employee stock option
granted by the Issuer on March 1, 2001 (the "March 2001 Option").  The March
2001 Option, which expires March

                                      -3-


1, 2011, became exercisable as to 333,333 Shares on March 1, 2002, and becomes
exercisable as to 333,333 Shares on March 1, 2003 and to the remaining 333,334
shares on March 1, 2004. It is the Reporting Person's present intention to
utilize individual funds and/or presently owned Shares to purchase any Shares he
may acquire pursuant to the Options (as defined in Item 6).

ITEM 4.   PURPOSE OF TRANSACTION.

The Reporting Person acquired the Original Shares for investment purposes.
Subject to compliance with applicable law, and depending on general market and
economic conditions affecting the Issuer and the Reporting Person's view of the
prospects for the Issuer and other relevant factors, the Reporting Person may
purchase additional Shares, including Shares which may be acquired pursuant to
the Options (as defined in Item 6), or dispose of some or all of his Shares from
time to time in open market transactions, private transactions or otherwise.

The Reporting Person participates in the formulation, determination and
direction of basic business decisions and policies of the Issuer by virtue of
his membership on the Issuer's Board of Directors and his service as an
executive officer of the Issuer.  For further discussion of (i) the Merger
Agreement which contains provisions relating to the Reporting Person's initial
and 1997 election to the Issuer's Board of Directors and (ii) the Employment
Agreement (as defined below) which contains provisions relating to the Reporting
Person's employment as an executive officer of the Issuer, see Item 6, below.

               reorganization or liquidation, involving the Issuer or any of its

        (c)    a sale or transfer of a material amount of assets of the Issuer
               or any of its subsidiaries;

        (d)    any change in the present board of directors or management of the

               term of directors or to fill any existing vacancies on the board;

        (e)    any material change in the present capitalization or dividend
               policy of the Issuer;

               corresponding thereto or other actions which may impede the
               acquisition of control of the Issuer by any person;

        (g)    causing a class of securities of the Issuer to be delisted from a
               national securities exchange or cease to be authorized to be
               quoted in an inter-dealer quotation system of a registered
               national securities association;

        (h)    a class of equity securities of the Issuer becoming eligible for
               termination of registration pursuant to Section 12(g)(4) of the
               Securities Exchange Act of 1934; or

        (i)    any action similar to any of those enumerated above.

ITEM 5.   INTEREST IN SECURITIES OF THE ISSUER.

        (a)    The 6,333,333 Shares beneficially owned by the Reporting Person
               (1,333,333 of which represent Shares the Reporting Person is
               entitled to acquire pursuant to the February 1999 Option and
               March 2001 Option, as described in Item 3) constitute
               approximately 9.2% of the total number of Shares outstanding,
               based on 68,653,583 Shares outstanding at March 26, 2002.

                                      -4-

          under the Securities Act of 1933, a total of 1,403,238 of the Original
          Shares for $41,888,859.67. The sale prices ranged from $29.5004 to
          $30.4211 per share. Except as set forth herein, the Reporting Person
          has not engaged in any transaction during the past 60 days in any
          securities of the Issuer.

     (d)  Not applicable.

     (e)  Not applicable.

ITEM 6. CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT TO
SECURITIES OF THE ISSUER.

As described in Item 3, the Merger Agreement sets forth the Reporting Person's
agreement pursuant to which he sold his interests in the Gold Strike Properties
in return for the issuance of the Original Shares, and the distribution of
$4,762,650 in cash, to the Reporting Person on the Closing Date.

In connection with the transactions contemplated by the Merger Agreement, the
Issuer's Bylaws were amended to increase the number of Class II Directors from
two to three.  Pursuant to the Merger Agreement, on the Closing Date, the
Reporting Person was elected by the Issuer's Board of Directors to fill the
Class II vacancy resulting from the foregoing amendment to the Bylaws for the
balance of the current term of such class.  The Merger Agreement also required
the Issuer, at the end of the Reporting Person's initial term as a member of the
Issuer's Board of Directors, to use its best efforts to cause the Reporting
Person (or another individual designated by the Reporting Person) to be
nominated for election to a full term when the Class II directors next stood for
election in 1996.  The Reporting Person was elected by the Issuer's stockholders
to serve a full three-year term on the Issuer's Board of Directors on June 21,
1996.  On June 17, 1999, the Reporting Person was elected by the Issuer's
stockholders to an additional three-year term which expires in 2002.

In connection with the Closing, the Reporting Person also entered into the
following agreements with the Issuer which relate to the management and
securities of the Issuer:  Employment Agreement, Standstill Agreement,
Registration Rights Agreement and Agreement Pursuant to Joint Venture Agreement.
Each of which is discussed below.

The Employment Agreement dated as of the Closing Date by and between the
Reporting Person and the Issuer required, among other things, the Issuer to
employ the Reporting Person as an executive officer for a term of three years
subject to automatic renewal unless the Reporting, Person or the Issuer provides
written notice to the contrary.  The Employment Agreement, pursuant to which the
Reporting Person has been employed as the Issuer's Vice Chairman of the Board
since June 18, 1998 and Executive Vice President from June 1, 1995 until June
18, 1998, has continued in effect since the Closing Date and terminates on May
31, 2002.

The Standstill Agreement dated as of the Closing Date by and among the Issuer
and Michael S. Ensign, the Reporting Person, David R. Belding, Peter A. Simon II
and Glenn W. Schaeffer (the "Standstill Agreement"), contained a number of
customary "standstill" restrictions, including limitations on the number of
Shares which the Reporting Person could beneficially own.  Pursuant to such
restrictions, which terminated on June 1, 2000, the Reporting Person agreed,
among other things and except in certain circumstances, for a five year period
beginning on the Closing Date (i) not to acquire more than 9.9% of the
outstanding equity securities of the Issuer, (ii) not to engage in the
solicitation of proxies and (iii) not to make any acquisition proposal.
Pursuant to a Stipulation of Settlement re Consolidated Class Action and
Derivative Claims dated April 16, 1996, the Issuer agreed to amend the
Standstill Agreement dated as of June 1, 1995 by and between, among others, the
Issuer and the Reporting Person (the "Standstill Agreement"), to clarify certain
duties of the Reporting Person.  On September 3, 1996, the Issuer and the
Reporting Person entered into Amendment No. 1 to the Standstill Agreement (the
"Amendment").  The Amendment, which is effective as of April 16, 1996, provides
that notwithstanding anything to the contrary in the

                                      -5-


Standstill Agreement, the Reporting Person must exercise his fiduciary duties in
evaluating and considering any unsolicited offers or proposals for the
acquisition of or merger with, or other proposed change in control of, the
Issuer.

The Registration Rights Agreement dated as of the Closing Date by and among the
Issuer and Michael S. Ensign, the Reporting Person, David R. Belding, Peter A.
Simon II, Glenn W. Schaeffer, Gregg H. Solomon, Antonio C. Alamo, Anthony
Korfman, William Ensign and Robert J. Verchota provides the Reporting Person
with certain demand and piggyback registration rights with respect to the Shares
acquired by him pursuant to the Merger Agreement.

The Agreement Pursuant to Joint Venture Agreement dated as of the Closing Date
by and among the Issuer and Michael S. Ensign, the Reporting Person and Glenn W.
Schaeffer, which has terminated, required the foregoing individuals to jointly
and severally pay to the Issuer liquidated damages upon the occurrence of
certain events relating to (i) the management of a joint venture which is
currently managed by an affiliate of the Issuer and (ii) such individuals'
employment with the Issuer or such individuals' beneficial ownership of the
capital stock of the Issuer.

On February 9, 1999, the Issuer granted to the Reporting Person the February
1999 Option, the terms of which are described in Item 3.  On March 1, 2001, the
Issuer granted to the Reporting Person the March 2001 Option, the terms of which
are described in Item 3.  On October 2, 2001, the Issuer granted to the
Reporting Person an employee stock option pursuant to which the Reporting Person
is entitled to purchase, at an exercise price of $17.25 per Share, up to 400,000
Shares (the "October 2001 Option" and, collectively with the March 2001 Option
and the February 1999 Option, the "Options").  The October 2001 Option, which
expires on October 1, 2011, becomes exercisable as to all of the 400,000 shares
on October 2, 2002.  The Shares the Reporting Person is entitled to purchase
pursuant to the October 2001 Option and 666,667 Shares the Reporting Person is
entitled to purchase pursuant to the March 2001 Option have not been included in
the number of Shares reported herein as beneficially owned by the Reporting
Person because, as described, the right to acquire those shares does not become
exercisable for more than 60 days following the date hereof.

The description of the terms of the Merger Agreement, Employment Agreement,
Standstill Agreement, Registration Rights Agreement, Agreement Pursuant to Joint
Venture Agreement and Options set forth herein does not purport to be a complete
statement of the parties' rights and obligations, and is qualified in its
entirety by reference to such agreements, which are set forth as Exhibits 99.1
to 99.10 hereto.  Reference is made to such agreements for a complete
description of the terms and provisions thereof and the agreement of the parties
thereunder.

Except as set forth above, there are no other contracts, arrangements,
understandings or relationships (legal or otherwise) among persons named in Item
2 and between such persons and any person with respect to any securities of the
Issuer, including but not limited to transfer or voting of any of the securities
of the Issuer, finder's fees, joint ventures, loan or option arrangements, puts
or calls, guarantees or profits, division of profits of loss, or the giving or
withholding of proxies, or a pledge or otherwise subject to a contingency the
occurrence of which would give another person voting power or investment power
over the securities of the Issuer.
