                                 PROXY STATEMENT

                               GENERAL INFORMATION

     This proxy statement is furnished in connection with the solicitation of
proxies by the Board of Directors of Ameristar Casinos, Inc. ("ACI" or the
"Company"), a Nevada corporation, for use only at its Annual Meeting of
Stockholders to be held on Friday, June 8, 2001, and any adjournments or
postponements thereof (the "Annual Meeting").

     Shares may not be voted unless the signed proxy card is returned or other
specific arrangements are made to have shares represented at the meeting. Any
stockholder of record giving a proxy may revoke it at any time before it is
voted by filing with the Secretary of ACI a notice in writing revoking it, by
duly executing a proxy bearing a later date, or by attending the Annual Meeting
and expressing a desire to revoke the proxy and vote the shares in person.
Stockholders whose shares are held in street name should consult with their
brokers or other nominees concerning procedures for revocation. Subject to such
revocation, all shares represented by a properly executed proxy card will be
voted as directed by the stockholder on the proxy card. IF NO CHOICE IS
SPECIFIED, PROXIES WILL BE VOTED "FOR" THE PERSONS NOMINATED BY THE BOARD OF
DIRECTORS AND "FOR" THE APPROVAL OF THE AMENDMENT TO THE COMPANY'S 1999 STOCK
INCENTIVE PLAN.

     In addition to soliciting proxies by mail, Company officers, Directors and
other regular employees, without additional compensation, may solicit proxies
personally or by other appropriate means. The total cost of solicitation of
proxies will be borne by ACI. Although there are no formal agreements to do so,
it is anticipated that ACI will reimburse banks, brokerage houses and other
custodians, nominees and fiduciaries for their reasonable expenses in forwarding
any proxy soliciting materials to their principals.

     Only stockholders of record at the close of business on April 27, 2001 are
entitled to receive notice of and to vote at the Annual Meeting. As of April 10,
2001, ACI had 20,568,677 shares of Common Stock outstanding, which constituted
all of the outstanding voting securities of ACI. Each share outstanding on the
record date is entitled to one vote on each matter. A majority of the shares of
Common Stock outstanding on the record date will constitute a quorum.

     Directors are elected by a plurality of votes cast. Stockholders may not
cumulate their votes for any one or more nominees for election. Under Nevada
law, the affirmative vote of a majority of the votes cast on any proposal at the
Annual Meeting generally will constitute the approval of the stockholders. Such
approval will also satisfy the requirements of The Nasdaq Stock Market, Inc. for
the continued designation of the Common Stock as a National Market Security.

     Abstentions and broker "non-votes" are counted for purposes of determining
the presence or absence of a quorum for the transaction of business but will not
be counted in the election of Directors or the vote to approve the amendment to
the 1999 Stock Incentive Plan. Thus, abstentions and broker "non-votes" will
have no effect on the election of Directors or the vote on the proposal to
approve the amendment to the 1999 Stock Incentive Plan. A broker "non-vote"
occurs when a nominee holding shares for a beneficial owner does not vote on a
particular proposal or matter, and so notifies the Company, because the nominee
does not have discretionary voting power with respect to that proposal or matter
and has not received voting instructions from the beneficial owner.

     Craig H. Neilsen, the Chairman of the Board, President and Chief Executive
Officer of the Company, owns 17,700,000 shares of the Company's Common Stock
(including 220,800 shares owned by an estate of which Mr. Neilsen is the
executor and with respect to which Mr. Neilsen has sole voting control), which
represents 86.1% of the voting power of the Company as of April 10, 2001. Mr.
Neilsen intends to vote all such shares in favor of the persons nominated by the
Board of Directors and in favor of approving the amendment to the 1999 Stock
Incentive Plan.

     It is anticipated that this proxy statement and accompanying proxy card
will first be mailed to stockholders on or about May 4, 2001.


                                 PROPOSAL NO. 1
                              ELECTION OF DIRECTORS

INFORMATION CONCERNING THE NOMINEES

     The Company's Articles of Incorporation provide that the Board of Directors
shall be classified, with respect to the time for which the Directors severally
hold office, into three classes, as nearly equal in number as possible as the
total number of Directors constituting the entire Board permits. The authorized
number of Directors is currently set at six, and there are two vacancies on the
Board of Directors. Of the four sitting Directors, two are Class C Directors
whose terms are expiring in 2001 and are being nominated for re-election by the
Company as described below. Biographical information concerning the nominees and
the other Directors of the Company is set forth under the caption "Directors and
Executive Officers." See "Security Ownership of Certain Beneficial Owners and
Management" for information regarding each such person's holdings of Common
Stock.

     The Board of Directors has nominated the incumbent Class C Directors to be
elected for a term expiring at the 2004 Annual Meeting of Stockholders, and
until such person's successor has been duly elected and qualified or until his
earlier death, resignation or removal. The incumbent Class C Directors nominated
are Craig H. Neilsen and Joseph E. Monaly.

     The Board of Directors has no reason to believe that its nominees will be
unable or unwilling to serve if elected. However, should the nominees named
herein become unable or unwilling to accept nomination or election, the persons
named as proxies will vote instead for such other person(s) as the Board of
Directors may recommend.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE "FOR" THE ELECTION OF THE
ABOVE-NAMED NOMINEES AS DIRECTORS.

                                 PROPOSAL NO. 2
               APPROVAL OF AMENDMENT TO 1999 STOCK INCENTIVE PLAN

     The Board of Directors has unanimously approved, subject to stockholder
approval at the meeting, an amendment (the "Amendment") to the Ameristar
Casinos, Inc. 1999 Stock Incentive Plan (as amended by the Amendment, the
"Plan"). The Amendment increases the number of shares available under the Plan
and increases the number of shares under option that may be granted to any
individual under the Plan in any one calendar year. The primary reason for the
Amendment is to allow for the granting of awards under the Plan: (i) to the
various employees that joined the Company in connection with the acquisition of
the Missouri properties, including the senior managers of the Missouri
properties pursuant to the terms of their employment agreements, and (ii) to
other new employees of the Company and other eligible participants on an ongoing
basis.

     The Plan is designed to (i) enable the Company and Related Companies (as
defined below) to attract, motivate and retain top-quality directors, officers,
employees, consultants, advisers and independent contractors, (ii) provide
substantial incentives for such persons to act in the best interests of the
stockholders of the Company and (iii) reward extraordinary effort by such
persons on behalf of the Company or a Related Company. The Plan provides for
awards in the form of stock options, which may be either "incentive stock
options" within the meaning of Section 422 of the Internal Revenue Code of 1986,
as amended (the "Code"), or non-qualified stock options, or restricted stock.

     As of April 30, 2001, there were options outstanding under the Plan and the
Management Stock Option Incentive Plan, the Company's previous stock incentive
plan, exercisable for 3,130,115 shares of Common Stock with per share exercise
prices ranging from $2.64 to $6.44 (with a weighted average exercise price of
$4.08) and with expiration dates ranging from 2003 to 2011. The Plan and the
Management Stock Option Incentive Plan are referred to below as the "Plans". As
of April 20, 2001, 211,347 shares of Common Stock had been issued upon the
exercise of stock options granted under the Plans. No shares of restricted stock
have been granted under the Plan. Prior to its amendment, the Plan authorized
the issuance of up to 2,600,000 shares of Common Stock in connection with awards
under the Plans and awards of up to 200,000 shares under option to any
individual in a single calendar year. As amended, the Plan authorizes the
issuance of up to 4,600,000 shares of Common Stock in connection with awards
under the Plans and awards of up to 1,000,000 shares under option to any
individual in a single calendar year. The Board of Directors believes that the
Plan has aided the Company in attracting, motivating and retaining quality
employees and management personnel.

     THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE "FOR" THE APPROVAL OF
THE AMENDMENT TO THE PLAN.

PRINCIPAL PROVISIONS OF THE PLAN

     The following summary of the Plan is qualified in its entirety by reference
to the full text of the Plan, which is attached as Appendix B to this Proxy
Statement.

     Shares. The total number of shares of Common Stock available for
distribution under the Plan, as amended by the Amendment, is 4,600,000;
provided, however, that no award of stock options or restricted stock may be
made under the Plan at any time if, after giving effect to such award, (i) the
total


                                      -9-
   12


number of shares of Common Stock issued upon the exercise of options under the
Plans plus (ii) the total number of shares of Common Stock issuable upon
exercise of all outstanding options of the Company under the Plans plus (iii)
the total number of shares of Common Stock underlying awards of restricted stock
under the Plan (whether or not the applicable restrictions have lapsed) would
exceed 4,600,000 shares.

     Shares awarded under the Plan may be authorized and unissued shares or
treasury shares. If shares subject to an option under the Plan cease to be
subject to such option, or shares under the Plan are forfeited, such shares will
again be available for future distribution under the Plan, unless the forfeiting
participant received any benefits of ownership such as dividends from the
forfeited award.

     Administration. The Plan provides for it to be administered by the
Compensation Committee of the Board of Directors of the Company (the "Board") or
such other committee of directors as the Board shall designate, which committee
shall consist solely of not less than two "non-employee directors" (as such term
is defined in Rule 16b-3 under the Securities Exchange Act of 1934 (the
"Exchange Act") or any successor rule ("Rule 16b-3")) who shall serve at the
pleasure of the Board, each of whom shall also be an "outside director" within
the meaning of Section 162(m) of the Code and Section 1.162-27 of the Treasury
Regulations or any successor provision(s) thereto ("Section 162(m)"); provided,
however, that if there are not two persons on the Board who meet the foregoing
qualifications, any such committee may be comprised of two or more directors of
the Company, none of which is an officer (other than a non-employee Chairman of
the Board of the Company) or employee of the Company or a Related Company. If no
such committee has been appointed by the Board, the Plan will be administered by
the Board. Such committee as shall be designated to administer the Plan or the
Board is hereinafter referred to as the "Committee." Notwithstanding any
provision of the Plan to the contrary, if such a committee has been designated
to administer the Plan, all actions with respect to the administration of the
Plan in respect of the members of such committee shall be taken by the Board.

     The Plan is currently administered by the Compensation Committee, which is
currently comprised of the Company's two independent directors, each of whom is
believed to be a non-employee director as defined for purposes of Rule 16b-3 and
an outside director as defined for purposes of Section 162(m). The Compensation
Committee has delegated certain authority with respect to the administration of
the Plan and the granting of awards under the Plan to Craig H. Neilsen, the
Company's President and Chief Executive Officer, in accordance with the terms of
the Plan.

     The Committee is authorized to, among other things, set the terms of awards
to participants and waive compliance with the terms of such awards. The
provisions attendant to the grant of an award under the Plan may vary from
participant to participant. The Committee has the authority to interpret the
Plan and adopt administrative regulations. The Committee may from time to time
delegate to one or more officers of the Company any or all of its authorities
under the Plan, except with respect to awards granted to persons subject to
Section 16 of the Exchange Act. The Committee must specify the maximum number of
shares that the officer or officers to whom such authority is delegated may
award, and the Committee may in its discretion specify any other limitations or
restrictions on the authority delegated to such officer or officers.

     Participation. The Committee may make awards to any directors, officers,
employees, consultants, advisers and independent contractors of the Company or a
Related Company, all of whom


                                      -10-
   13


are eligible to participate in the Plan. A "Related Company" is any corporation,
partnership, joint venture or other entity in which the Company owns, directly
or indirectly, at least a 20% beneficial ownership interest. The participants in
the Plan are selected from among those eligible in the sole discretion of the
Committee.

     Awards to Participants.

     1. Stock Options.

          Incentive stock options ("ISOs") and non-qualified stock options may
     be granted for such number of shares of Common Stock as the Committee
     determines, provided that no participant may be granted stock options in
     any calendar year on more than 1,000,000 shares of Common Stock. A stock
     option will be exercisable at such times, over such term and subject to
     such terms and conditions as the Committee determines. The exercise price
     of stock options is determined by the Committee.

          The exercise price of an ISO may not be less than the per share fair
     market value of the Common Stock on the date of grant, or 110% of such fair
     market value if the recipient owns, or would be considered to own by reason
     of Section 424(d) of the Code, more than 10% of the total combined voting
     power of all classes of stock of the Company or any parent or subsidiary of
     the Company (a "10% Stockholder"). In addition, an ISO may not be
     exercisable more than 10 years after the date such ISO is awarded (5 years
     after the date of award if the recipient is a 10% Stockholder). An ISO also
     may not be transferable other than by will or by the laws of descent and
     distribution. The aggregate fair market value (determined as of the time a
     stock option is granted) of Common Stock with respect to which ISOs granted
     after December 31, 1986 are exercisable for the first time by a participant
     in any calendar year (under the Plan and any other plans of the Company or
     any subsidiary or parent corporation) may not exceed $100,000.

          Payment of the exercise price may be made in such manner as the
     Committee may provide, including cash, delivery of shares of Common Stock
     already owned or subject to award under the Plan. The Committee may provide
     that all or part of the shares received upon exercise of an option using
     restricted stock will be restricted stock.

          Upon an optionee's termination of employment or other qualifying
     relationship, the option will be exercisable to the extent determined by
     the Committee; provided, however, that unless employment or such other
     qualifying relationship is terminated for cause (as may be defined by the
     Committee in connection with the grant of any stock option), the stock
     option will remain exercisable (to the extent that it was otherwise
     exercisable on the date of termination) for at least six months from the
     date of termination if termination was caused by death or disability or at
     least 90 days from the date of termination if termination was caused by
     other than death or disability. The Committee may provide that an option
     that is outstanding on the date of an optionee's death will remain
     outstanding for an additional period after the date of such death,
     notwithstanding that such option would expire earlier under its terms.

          A stock option agreement for a non-qualified option may permit an
     optionee to transfer the stock option to his or her children, grandchildren
     or spouse ("Immediate Family"), to one or


                                      -11-
   14

     more trusts for the benefit of such Immediate Family members, or to one or
     more partnerships or limited liability companies in which such Immediate
     Family members are the only partners or members if (i) the agreement
     setting forth the stock option expressly provides that the option may be
     transferred only with the express written consent of the Committee, and
     (ii) the optionee does not receive any consideration in any form whatsoever
     for such transfer other than the receipt of an interest in the trust,
     partnership or limited liability company to which the non-qualified option
     is transferred. Any stock option so transferred will continue to be subject
     to the same terms and conditions as were applicable to the option
     immediately prior to its transfer. Except as described above, stock options
     are not transferable by the optionee otherwise than by will or by the laws
     of descent and distribution.

     2. Restricted Stock.

          In making an award of restricted stock, the Committee will determine
     the periods, if any, during which the stock is subject to forfeiture, and
     the purchase price, if any, for the stock. The vesting of restricted stock
     may be unconditional or may be conditioned upon the completion of a
     specified period of service with the Company or a Related Company, the
     attainment of specific performance goals or such other criteria as the
     Committee may determine.

          During the restricted period, the award holder may not sell, transfer,
     pledge or assign the restricted stock, except as may be permitted by the
     Committee. The certificate evidencing the restricted stock will be
     registered in the award holder's name, although the Committee may direct
     that it remain in the possession of the Company until the restrictions have
     lapsed. Except as may otherwise be provided by the Committee, upon the
     termination of the award holder's service with the Company or a Related
     Company for any reason during the period before all restricted stock has
     vested, or in the event the conditions to vesting are not satisfied, all
     restricted stock that has not vested will be subject to forfeiture and the
     Committee may provide that any purchase price paid by the award holder, or
     an amount equal to the restricted stock's fair market value on the date of
     forfeiture, if lower, will be paid to the award holder. During the
     restricted period, the award holder will have the right to vote the
     restricted stock and to receive any cash dividends, if so provided by the
     Committee. Stock dividends will be treated as additional shares of
     restricted stock and will be subject to the same terms and conditions as
     the initial grant, unless otherwise provided by the Committee.

     Acceleration of Vesting in Certain Circumstances. Upon the dissolution or
liquidation of the Company or upon any reorganization, merger or consolidation
with one or more corporations or other entities as a result of which the Company
is not the surviving entity, or upon a sale of all or substantially all of the
assets of the Company to another corporation or entity, the Committee may take
such action, if any, as it in its discretion may deem appropriate: (i) to
accelerate the time within which and the extent to which stock options may be
exercised, to terminate stock options at or prior to the date of any such event
or to provide for the assumption of stock options by surviving, consolidated,
successor or transferee corporations or entities; or (ii) to waive any
restrictions applicable to any outstanding restricted stock awards under the
Plan, following which such shares shall be deemed fully vested, or to provide
that any securities or other consideration issuable to the participant in
respect of such restricted stock by the surviving, consolidated, successor or
transferee corporations or entities shall remain subject to the restrictions
applicable to such restricted stock award.




                                      -12-
   15



     Amendment and Termination. No awards may be granted under the Plan more
than 10 years after the date of approval of the Plan by the stockholders of the
Company. The Board may discontinue the Plan at any earlier time and may amend it
from time to time, except that no amendment or discontinuation may adversely
affect any outstanding award without the holder's written consent. Amendments
may be made without stockholder approval except as required to satisfy any
applicable mandatory legal or regulatory requirements, or as required for the
Plan to satisfy the requirements of Section 162(m), Section 422 of the Code or
any other non-mandatory legal or regulatory requirements if the Board of
Directors deems it desirable for the Plan to satisfy any such requirements.

     Adjustment. In the event of any merger, reorganization, consolidation, sale
of substantially all assets, recapitalization, stock dividend, stock split,
spin-off, split-up, split-off, distribution of assets or other change in
corporate structure affecting the Common Stock, a substitution or adjustment, as
may be determined to be appropriate by the Committee in its sole discretion,
will be made in the aggregate number of shares reserved for issuance under the
Plan, the maximum number of shares with respect to which stock options may be
granted to any participant during any calendar year, the number of shares
subject to outstanding awards and the amounts to be paid by award holders or the
Company, as the case may be, with respect to outstanding awards. No such
adjustment may increase the aggregate value of any outstanding award.

CERTAIN FEDERAL INCOME TAX CONSEQUENCES

     The following is a summary of certain federal income tax aspects of awards
made under the Plan based upon the laws in effect on April 1, 2001. Since the
tax consequences to each participant will differ depending on the terms of the
award and the participant's specific situation, participants should not rely on
this summary for individual tax advice. Rather, each participant should consult
his or her own tax advisor, prior to the exercise of an option or acquisition of
restricted stock, regarding the pertinent federal, state and local income tax
and other tax consequences of exercising options or owning restricted stock.

     1. Incentive Stock Options.

          Generally, no taxable income is recognized by the participant upon the
     grant of an ISO or upon the exercise of an ISO during the period of the
     participant's employment with the Company or one of its subsidiaries or
     within three months (12 months, in the event of permanent and total
     disability, or the term of the option, in the event of death) after
     termination. However, the exercise of an ISO may result in a significant
     alternative minimum tax liability to the participant, and thus participants
     should carefully consider alternative minimum tax consequences prior to
     exercising an ISO. If the participant continues to hold the shares acquired
     upon the exercise of an ISO for at least two years from the date of grant
     and one year from the transfer of the shares to the participant, then
     generally: (a) upon the sale of the shares, any difference between the
     amount realized and the option price will be treated as long-term capital
     gain or loss; and (b) no deduction will be allowed to the employer
     corporation for federal income tax purposes.

          If Common Stock acquired upon the exercise of an ISO is disposed of
     prior to the expiration of the one-year or two-year holding periods
     described above (a "disqualifying disposition"), then generally in the year
     of disposition: (a) the participant will recognize ordinary


                                      -13-
   16


     income in an amount equal to the excess, if any, of the fair market value
     of the shares on the date of exercise (or, if less, the amount realized on
     disposition of the shares) over the option exercise price; and (b) the
     employer corporation will be entitled to deduct any such recognized amount.
     Any further gain recognized by the participant on such disposition
     generally will be taxed as short-term or long-term capital gain, depending
     on whether the shares were held by the participant for more than one year,
     but such additional amounts will not be deductible by the employer
     corporation.

          According to proposed Treasury Regulations, in general, no gain or
     loss will be recognized by a participant who uses shares of Common Stock
     rather than cash to exercise an ISO. A number of new shares of Common Stock
     acquired equal to the number of shares surrendered will have a basis and
     capital gain holding period equal to those of the shares surrendered
     (although such shares will be subject to new holding periods for
     disqualifying disposition purposes beginning on the acquisition date). To
     the extent new shares of Common Stock acquired pursuant to the exercise of
     the ISO exceed the number of shares surrendered, such additional shares
     will have a zero basis and will have a holding period beginning on the date
     the ISO is exercised. The use of Common Stock acquired through exercise of
     an ISO to exercise an ISO will constitute a disqualifying disposition with
     respect to such Common Stock if the applicable holding period requirement
     has not been satisfied.

     2. Non-Qualified Stock Options.

          Except as noted below with respect to officers and directors subject
     to Section 16 of the Exchange Act ("Insiders"), with respect to
     non-qualified stock options: (a) no income is recognized by the participant
     at the time the option is granted; (b) generally upon exercise of the
     option, the participant recognizes ordinary income in an amount equal to
     the difference between the option exercise price and the fair market value
     of the shares on the date of exercise and the employer corporation will be
     entitled to a tax deduction in the same amount, to the extent that such
     income is considered reasonable compensation; and (c) at disposition, any
     appreciation after the date of exercise generally is treated either as
     short-term or long-term capital gain, depending on whether the shares were
     held by the participant for more than one year, and such appreciation is
     not deductible by the employer corporation.

          No gain or loss will be recognized by a participant with respect to
     shares of Common Stock surrendered to exercise a non-qualified stock
     option. A number of new shares acquired equal to the number of shares
     surrendered will have a tax basis and capital gain holding period equal to
     those of the shares surrendered. The participant will recognize ordinary
     income in an amount equal to the fair market value of the additional shares
     acquired at the time of exercise (except as noted below with respect to
     Insiders). Such additional shares will be deemed to have been acquired on
     the date of such recognition of income and will have a tax basis equal to
     their fair market value on such date.

     3. Restricted Stock.

          A participant receiving restricted stock generally will recognize
     income in the amount of the fair market value of the restricted stock at
     the time the stock becomes transferable or is no




                                      -14-
   17



     longer subject to a substantial risk of forfeiture, whichever comes first,
     less the consideration, if any, paid for the stock. However, a participant
     may elect within 30 days of the transfer of the restricted stock to the
     participant, under Section 83(b) of the Code, to recognize ordinary income
     on the date of grant of the restricted stock in an amount equal to the
     excess of the fair market value of the shares on such date (determined
     without regard to the restrictions other than restrictions which by their
     terms will never lapse) over their purchase price. The holding period to
     determine whether the participant has long-term or short-term capital gain
     on a subsequent disposition of the shares generally begins when ordinary
     income was recognized, and the tax basis for such shares generally will be
     the amount of income that was recognized plus the amount, if any, paid for
     the stock. However, if a participant makes the election under Section 83(b)
     of the Code, in general no deduction will be allowed for the income
     recognized as a result of that election if the shares are later forfeited
     to the Company

     4. Special Rules Applicable to Insiders.

          Insiders may be subject to special tax rules upon the exercise of an
     option if the sale of the underlying shares could give rise to liability
     under Section 16(b) of the Exchange Act, and the tax consequences to an
     Insider may differ depending on whether the Insider makes an election under
     Section 83(b) of the Code within 30 days of the date of exercise.

     5. Dividends.

          Dividends paid on restricted stock prior to the date on which the
     forfeiture restrictions lapse generally will be treated as compensation
     that is taxable as ordinary income to the participant and will be
     deductible by the employer corporation. If, however, the participant makes
     a timely Section 83(b) election with respect to the restricted stock, the
     dividends will be taxable as ordinary dividend income to the participant
     and will not be deductible by the employer corporation.

     6. Withholding Taxes.

          A participant in the Plan may be required to pay the employer
     corporation an amount necessary to satisfy the applicable federal and state
     law requirements with respect to the withholding of taxes on wages, or to
     make some other arrangements to comply with such requirements. The employer
     has the right to withhold from salary or otherwise to cause a participant
     (or the executor or administrator of the participant's estate or the
     participant's distributee or transferee) to make payment of any federal,
     state, local or other taxes required to be withheld with respect to any
     award under the Plan. The Plan authorizes the Committee to permit
     participants to use the shares issuable under the Plan to satisfy
     withholding obligations.

     7. Company Deductions.

          As a general rule, the Company or one of its subsidiaries will be
     entitled to a deduction for federal income tax purposes at the same time
     and in the same amount that a participant in the Plan recognizes ordinary
     income from awards under the Plan, to the extent that such income is



                                      -15-
   18


     considered reasonable compensation and currently deductible (and not
     capitalized) under the Code and certain reporting requirements are
     satisfied.

          However, Section 162(m) limits to $1 million the annual tax deduction
     that the Company and its subsidiaries can take with respect to the
     compensation of each of certain executive officers unless the compensation
     qualifies as "performance based" or certain other exemptions apply. The
     Company may or may not be subject to the Section 162(m) limitation on the
     amount of the deduction upon the exercise of a non-qualified stock option,
     depending on the terms of the award. A non-qualified stock option granted
     under the Plan (and an ISO, to the extent there is a disqualifying
     disposition) will only qualify as "performance based" compensation under
     Section 162(m) if the exercise price is not less than the fair market value
     of the Common Stock on the date of grant and certain other requirements are
     met. Any stock options granted with an exercise price that is less than the
     fair market value of the Common Stock on the date of grant will be subject
     to the Section 162(m) limitation. Compensation arising from restricted
     stock awards under the Plan will not qualify as "performance based"
     compensation under the Regulations; therefore, the Company will be subject
     to the Section 162(m) limitation for compensation attributable to an award
     of restricted stock. Deductions may also be disallowed if they are "excess
     parachute payments" as discussed below.

     8. Effect of Change in Control.

          The Committee has discretion to accelerate vesting of stock options or
     restricted stock awards in connection with certain events that may
     constitute a change in ownership or effective control of the Company or
     sale of a substantial portion of the Company's assets. In that event and
     depending upon the individual circumstances of the participant, certain
     amounts with respect to such awards may constitute "excess parachute
     payments" under the "golden parachute" provisions of the Code. Pursuant to
     these provisions, a participant will be subject to a 20% excise tax on any
     "excess parachute payments" and the Company will be denied any deduction
     with respect to such payments.

BENEFITS UNDER THE PLAN

     As of April 20, 2001, there were approximately 6,400 employees and
Directors of the Company and Related Companies eligible to participate in the
Plan. The benefits that will be received by or allocated to various participants
in the Plan is not currently determinable. Since the Plan does not specify a
minimum exercise price for options or minimum purchase price for awards of
restricted stock, for federal income tax purposes the maximum compensation
payable under the Plan to participants, during the term of the Plan and awards
granted thereunder is equal to the number of shares of Common Stock with respect
to which awards may be issued thereunder, multiplied by the value of such shares
on the date such compensation is measured. On April 20, 2001, the closing per
share price of the Common Stock was $7.59.

                             EXECUTIVE COMPENSATION

         REPORT OF THE COMPENSATION COMMITTEE AND BOARD OF DIRECTORS ON
                             EXECUTIVE COMPENSATION

     In 2000, the Compensation Committee of Ameristar Casinos, Inc. consisted of
Larry A. Hodges, Paul I. Corddry and, until March 2000, Warren E. McCain. None
of the members is an employee or officer of the Company. The Compensation
Committee administers the Company's stock incentive plans (including the
Management Stock Option Incentive Plan (which was terminated in June 1999) and
the 1999 Stock Incentive Plan, as amended), pursuant to which employees of the
Company (including its executive officers) may receive stock option and
restricted stock grants. The Compensation Committee also reviews salaries and
other compensation of the executive officers of the Company. None of the actions
or recommendations of the Compensation Committee in 2000 were modified or
rejected by the Board of Directors.

General Compensation Philosophy

     The Compensation Committee tries to compensate the Company's officers in a
fashion that will attract, retain, motivate and appropriately reward those
individuals who are responsible for the Company's profitability and growth. The
compensation of executive officers has historically been determined primarily on
subjective factors and competitive requirements.

     In 2000, all compensation decisions were based on strictly subjective
determinations. Compensation for the Company's executive officers in 2000
consisted primarily of salary, a discretionary bonus and, in the case of Messrs.
Kanofsky and Steinbauer, the grant of stock options under the Company's 1999
Stock Incentive Plan. Executive officers also participated in benefit plans
available to employees generally, including a medical plan, a 401(k) plan, and
group life insurance.

     In making its determinations as to the amount of cash compensation, the
Committee considered, among other things, (i) the Company's financial results
during 2000, (ii) the extraordinary services rendered by the executive officers
during the year, including services rendered in connection with the Company's
acquisition of two properties in Missouri and the related financing
transactions, (iii) the market performance of the Company's stock, (iv) the
compensation paid to the executive officers in prior years, (v) the
recommendation of the Company's chief executive officer, and (vi) the amount of
compensation paid by the Company's competitors to their executive officers. No
specific weight was assigned to any particular factor.

     In 2000 the Compensation Committee, and the Chief Executive Officer acting
on delegated authority, awarded stock options to 112 employees of the Company or
its subsidiaries to purchase an aggregate of 1,969,542 shares of the Company's
Common Stock. The per share exercise price for stock option awards covering
these shares ranged from $3.88 to $5.56, with a weighted average per share
exercise price of $4.67. Of these options, options covering 70,000 shares were
awarded to Mr. Kanofsky and options covering 20,000 shares were awarded to Mr.
Steinbauer, each of whom is an executive officer of the Company, at a per share
exercise price of $4.72. The Committee believes it is both appropriate and
important that the long-term economic interests of its executive officers should
be aligned with those of the Company's stockholders.



                                      -17-
   20


     Effective April 2001, the Company has implemented a non-qualified deferred
compensation plan that allows participants to defer a portion of their salary
and bonus. The Company matches five percent of participants' contributions,
which matching contributions vest over a five-year period. There are currently
approximately 55 participants in the deferred compensation plan Company-wide.

Section 162(m) of the Internal Revenue Code

     Section 162(m) of the Internal Revenue Code disallows a deduction for
federal income tax purposes of most compensation exceeding $1,000,000 in any
year paid to the Company's chief executive officer and the four other most
highly compensated executive officers of a publicly-traded corporation. The
Company was not impacted by section 162(m) in 2000. In future years, the
Compensation Committee intends to take into account the effect of section 162(m)
if the compensation payable to any executive officer approaches $1,000,000.
However, the fact that compensation above $1,000,000 may not be deductible for
federal income tax purposes will not necessarily preclude the award of such
compensation if the Compensation Committee believes it is otherwise justified.

Compensation of Chief Executive Officer

     The Company's chief executive officer is in a unique position in that he
owns approximately 86.1% of the outstanding stock of the Company. He has not
been granted any awards under the Company's stock incentive plans, and the
Compensation Committee is not inclined to do so. The Compensation Committee
believes that the interests of the chief executive officer are already aligned
with those of the stockholders. In the opinion of the Committee, awards under
the Company's stock incentive plans to the chief executive officer will not
provide a material incentive to him. The Compensation Committee believes that
the chief executive officer must be compensated primarily by cash and by
deferred compensation plans.

     In 2000, the Company's chief executive officer received a salary of
$375,000 and a cash bonus of $375,000. These are the same salary and bonus that
the chief executive officer has received from the Company or a subsidiary since
the 1990 fiscal year.

     The Compensation Committee used strictly subjective factors in deciding the
bonus amount. The Compensation Committee considered a number of factors
including (i) the advancement of the Company and its subsidiaries since the
chief executive officer assumed leadership in 1983; (ii) the achievements of the
Company in 2000, including completing the acquisition of the two Missouri
properties and the related refinancing transactions, as well as the improved
performance of the Company's properties; (iii) the fact the chief executive
officer is also the majority stockholder of the Company and thereby is
significantly motivated to create long-term increases in stockholder value; (iv)
the fact the chief executive officer has not received a raise in his salary or
in his cash bonus since 1990; (v) the profitability of the Company in 2000; (vi)
the performance of the Company's stock in 2000; and (vii) the fact the chief
executive officer requested that his salary and bonus not be increased. No
particular weight was given to any factor. The Committee balanced certain of the
factors in the same manner as discussed above with respect to the other
executive officers of the Company. There is no quantifiable relationship between
the Company's performance and the compensation paid to the chief executive
officer.

(1)  Amounts shown include cash compensation earned for the periods reported
     whether paid or accrued in such periods.
(2)  As of April 10, 2001, the current annual salary levels for the Named
     Executive Officers were: Mr. Neilsen -$375,000; Mr. Kanofsky - $350,000;
     and Mr. Steinbauer - $275,000.
(3)  During 2000, 1999 and 1998, the Named Executive Officers received personal
     benefits, the aggregate amounts of which for each Named Executive Officer
     did not exceed the lesser of $50,000 or 10% of the total of the annual
     salary and bonus reported for such Named Executive Officer in such years.
(4)  In the case of Mr. Steinbauer, the number of shares underlying options/SARs
     granted in 1998 reflects the December 1998 repricing of outstanding options
     exercisable for 100,000 shares and the December 1998 grant of options
     exercisable for 32,000 shares. The Named Executive Officers did not receive
     any restricted stock awards or long-term incentive plan payouts in 2000,
     1999 or 1998.
(5)  These amounts represent matching contributions under the Company's 401(k)
     plan.
(6)  Mr. Kanofsky became the Company's Senior Vice President of Legal Affairs on
     September 1, 1999, at which time he received a "sign-on bonus" of $100,000.

EMPLOYMENT AGREEMENTS

     The Company and Mr. Steinbauer entered into a three-year employment
agreement commencing November 15, 1993, which is subject to automatic renewal
for a two-year period at the end of each term unless terminated by either party
with at least three months' prior written notice. The employment agreement
includes a covenant not to compete for a term of one year after termination of
the officer's employment. This covenant applies only to competing activities
within a 90-mile radius of the operations of the Company. The agreement provides
that in the event that Mr. Steinbauer's employment is terminated by the Company
without "cause" (as defined in the agreement), or by Mr. Steinbauer as a result
of a reduction in his duties or compensation, he would be entitled to a
severance payment in an amount equal to six months' base salary.

     The Company and Mr. Kanofsky entered into a one-year employment agreement
with a term commencing September 1, 1999, which is subject to automatic renewal
for a one-year period at the end of each term unless terminated by either party
30 days prior to the expiration of the then-present term. The employment
agreement includes a covenant not to compete for a term of one year after
termination of the officer's employment. This covenant applies only to competing
activities that target the Las Vegas "locals" market. The agreement provides
that in the event that Mr. Kanofsky's employment is terminated by the Company
without "cause" (as defined in the agreement), or by Mr. Kanofsky generally as a
result of a reduction in his duties or compensation following a "change in
control" (as defined in the agreement), he would be entitled to a severance
payment in an amount equal to his annual base salary.

     The Company has not entered into employment or similar agreements with Mr.
Neilsen.

     The Company has entered into an indemnification agreement with each of its
Directors and executive officers. These agreements require the Company, among
other things, to indemnify such persons against certain liabilities that may
arise by reason of their status or service as Directors or officers (other than
liabilities arising from actions involving intentional misconduct, fraud or a
knowing violation of law), to advance their expenses incurred as a result of a
proceeding as to which they may be indemnified and to cover such persons under
any directors' and officers' liability insurance policy maintained by the
Company. These indemnification agreements are separate and independent of
indemnification rights under the Company's Bylaws and are irrevocable.

                            REPORT OF AUDIT COMMITTEE

     During fiscal 2000, the Audit Committee of the Board of Directors developed
a charter for the Audit Committee, which was approved by the Board on May 1,
2000. The complete text of the Audit Committee Charter, which reflects standards
set forth in new SEC regulations and Nasdaq rules, is attached as Appendix A to
this Proxy Statement.

     In conjunction with its activities during the Company's 2000 fiscal year,
the Audit Committee has reviewed and discussed the Company's audited financial
statements with management of the Company. The members of the Audit Committee
have also discussed with the Company's independent auditors the matters required
to be discussed by SAS 61 (Codification of Statements on Auditing Standards, AU
Section 380). The Audit Committee has received from the Company's independent
accountants the written disclosures and the letter required by Independence
Standards Board Standard No. 1, Independence Discussions with Audit Committees,
and has discussed with the independent accountants their independence. Based on
the foregoing review and discussions, the Audit Committee recommended to the
Board of Directors of the Company that the audited financial statements be

services are set forth below:


                                                                                 
    Audit and review of the
    Company's 2000 financial statements.........................................     $256,000

    Services related to financial
    information systems design and implementation...............................     $      0

    All other services (approximately 84% of which are
    services traditionally provided by the audit firm, such as tax services,
    services related to registration statements and
    securities offerings and services related to benefit plan audits)...........     $479,000



The Audit Committee has considered whether the provision of non-audit services
by the Company's principal auditor is compatible with maintaining auditor
independence.

                              CERTAIN TRANSACTIONS

     Commencing April 1, 1997, Neilsen & Company (a limited liability company in
which Mr. Neilsen owns a controlling equity interest) leased from Lynwood
Shopping Center certain of the office space previously leased by the Company.
Cactus Pete's, Inc., a subsidiary of the Company ("CPI"), concurrently subleased
from Neilsen & Company the right to use certain offices in this space and the
common areas through December 31, 2001. In 2000, CPI paid $19,825 to Neilsen &
Company for rent and expenses under this sublease in 2000 and 1999. There was no
balance outstanding for rent or expenses at December 31, 2000. These offices
support CPI's casino-hotel operations in Jackpot, Nevada, at the Idaho border
due south of Twin Falls. The offices previously supported the Company's
executive offices, which are now located in Las Vegas, Nevada.

     The Company leases from Neilsen & Company two condominiums located in Sun
Valley, Idaho. These leases, which required the Company to pay an aggregate
monthly rental rate of $3,500 per month, expired on December 31, 1998. The
Company has continued to lease the two condominiums on a month-to-month basis
since January 1, 1999 at an aggregate monthly rental rate of $3,675 plus
maintenance, supply and utility costs (pending the approval of the Board of
Directors). The properties are made available by the Company at no charge to
management personnel and certain business associates. The Company believes that
the condominiums are a valuable asset in strengthening management morale and
maintaining goodwill with important business contacts. The Company believes that
the rental rates paid and proposed to be paid by the Company are within the
range of rates generally charged for such properties in Sun Valley.

     A portion of the services of one of the Company's employees was provided to
Neilsen & Company until July 1, 1997, at which time this employee terminated
service with the Company and became an employee of Neilsen & Company. The total
estimated amount due to the Company for these services at December 31, 1998 was
approximately $25,104 ($13,104 for a portion of the 1996 services and $12,000
for 1997 services), representing approximately half of the salary and additional
payroll burden for this employee. Payment of the outstanding balance has been
deferred pending an analysis of amounts due to Neilsen & Company from the
Company for various services performed by Neilsen & Company and amounts due to
the Company from Neilsen & Company for certain telephone expenses paid by the
Company on behalf of Neilsen & Company. Among others, the services provided by
Neilsen & Company to the Company included assistance with the relocation of the
Company's offices to Las Vegas, Nevada, litigation and arbitration support
services, licensing application assistance and accounts payable assistance. In
addition to the foregoing, Neilsen & Company provided services to the Company
during 1999 and 2000 in connection with the Company's license application for a
potential casino project in South St. Louis County and provided services in 2000
in connection with the Company's license applications for the acquisitions of
the two Missouri properties. In April 2001, Neilsen & Company billed the Company
$15,328 for the services that were provided in 1999 and $15,098 for the services
that were provided in 2000, which amounts were based on the number of hours that
employees of Neilsen & Company spent in providing these services. Other than
these license applications, Neilsen & Company has provided only minimal services
to the Company since 1997.

     Mr. Neilsen is the president, director and sole stockholder of
Intermountain Express, Inc. ("Intermountain"), a transportation concern that
provides CPI with package delivery services between Jackpot and Twin Falls,
Idaho. Intermountain contracts with CPI for the use of CPI's drivers by


                                      -24-
   27


     Intermountain. In 2000, CPI paid $29,975 to Intermountain for package
delivery services in 1999 and 2000. Intermountain has ceased providing these
services for CPI and there was no outstanding balance due from CPI to
Intermountain at December 31, 2000. CPI charged Intermountain $9,754 in 2000 for
contracted driver services and miscellaneous fuel and van maintenance expenses
provided by CPI in 2000. During 2000, Intermountain paid all of the amount
charged together with $7,422 that was outstanding at December 31, 1999 for such
services performed in 1999. CPI has ceased providing these services for
Intermountain and there was no outstanding balance due from Intermountain to CPI
at December 31, 2000. The Company believes that these relationships between CPI
and Intermountain have been beneficial to it.

     The Company has adopted a policy requiring transactions with affiliates to
be on terms no less favorable to the Company than could be obtained from
unaffiliated parties. Each of the completed transactions described above has
been approved by the Company's Board of Directors. In the opinion of management,
the terms of the above transactions were at least as fair to the Company as
could have been obtained from unaffiliated parties.

     Ray Neilsen, the Company's Vice President of Brand Development and Acting
General Manager at Ameristar Vicksburg, is the son of Craig H. Neilsen, the
Company's President and Chief Executive Officer. Ray Neilsen has held various
other positions with the Company for the past 10 years. Ray Neilsen received
salary and bonus compensation of $157,000 in 2000 as well as perquisites and
other employee benefits. The Company has provided housing to Ray Neilsen since
early 2000 when he temporarily relocated to Vicksburg to become Acting General
Manager of Ameristar Vicksburg. In addition, the Company pays approximately
$3,600 per month for Ray Neilsen's housing related expenses in Las Vegas.

                             AMERISTAR CASINOS, INC.
                             AUDIT COMMITTEE CHARTER
                             (Effective May 1, 2000)


I.   OVERVIEW AND PURPOSE.

     The purpose of the Audit Committee (the "Committee") of Ameristar Casinos,
Inc. (the "Company") is to assist the Company's Board of Directors (the "Board")
in fulfilling its fiduciary obligations and its general oversight
responsibilities by evaluating the Company's overall control environment and
general corporate governance. More specifically, the Committee's primary goals
are to serve as an independent and objective party to monitor the Company's
financial reporting process and internal control systems, to review and evaluate
the audit efforts of the Company's independent accountants and internal audit
department and to provide an open avenue of communication among the Company's
independent accountants, internal audit department, management personnel and the
Board.

     The Committee will accomplish these objectives by reviewing, among other
things: (1) the Company's financial reports and other financial information of
the Company that is provided to the public, governmental agencies or any stock
exchange or automated quotation system on which the Company's stock is listed,
designated for trading or otherwise quoted; (2) the Company's systems of
internal controls regarding finance and accounting matters as established from
time to time by the Company's management personnel and the Board; and (3) the
Company's accounting, financial reporting and internal and external auditing
processes generally.

     While the Committee has the responsibilities and authority set forth in
this Charter, it is not the duty of the Committee to plan or conduct audits or
to determine that the Company's financial statements are complete and accurate
and are in accordance with generally accepted accounting principles. This is the
responsibility of the Company's management personnel and the Company's
independent accountants. Nor is it the duty of the Committee to conduct
investigations, to resolve disagreements, if any, between the Company's
management personnel and the Company's independent accountants or to assure
compliance with laws and regulations and with the Company's Gaming Compliance
Program or codes of conduct.

II.  COMPOSITION OF THE COMMITTEE.

     The Committee shall be comprised of three directors, each of whom shall be
an Independent Director (as such term is defined below). Each member of the
Committee shall have a sufficient working familiarity with basic finance and
accounting practices to be capable of reading and understanding the Company's
fundamental financial statements, such as its balance sheet, statement of
operations and statement of cash flows, or will become able to do so within a
reasonable period of time after his or her appointment to the Committee. In
addition, at least one member of the Committee shall have past employment
experience in finance or accounting, requisite professional certification in
accounting, or other comparable experience or background


                                      A-1
   30


that results in such Committee member's financial sophistication (such as,
without limitation, being or having been a chief executive officer, chief
financial officer or other senior officer with financial oversight
responsibilities). Each member of the Committee shall be entitled to
indemnification by the Company for such member's actions as a member of the
Audit Committee in accordance with the terms and conditions of the
Indemnification Agreement between such member and the Company, the Company's
Bylaws and otherwise as such member is entitled with respect to such member's
services as a member of a committee of the Board.

     As used in this Charter, the term Independent Director means a director who
at the time of determination:

     o    is not an officer or employee of the Company or its subsidiaries or
          any other individual having a relationship that, in the opinion of the
          Board, would interfere with the exercise of independent judgment in
          carrying out the responsibilities of a director;

     o    is not currently, and has not been during any of the past three years,
          employed by the Company or any entity controlling, controlled by or
          under common control with the Company (an "Affiliate");

     o    has not received compensation from the Company or any Affiliate in
          excess of $60,000 (other than compensation in any form for board
          service, benefits under a tax-qualified retirement plan or
          non-discretionary compensation) during the immediately preceding
          fiscal year of the Company;

     o    is not an immediate family member of a person who is, or has been
          during any of the past three years, an executive officer of the
          Company or any Affiliate ("immediate family member" includes a
          person's spouse, parents, children, siblings, mother-in-law,
          father-in-law, brother-in-law, sister-in-law, son-in-law,
          daughter-in-law and anyone who resides in such person's home);

     o    is not a partner in, or a controlling shareholder or an executive
          officer of, any for-profit business organization to which the Company
          or any Affiliate made, or from which the Company or any Affiliate
          received, payments (other than those arising solely from investments
          in the securities of the Company or any Affiliate) in any of the
          immediately preceding three (3) full fiscal years of the Company that
          exceed five percent (5%) of the Company's or the business
          organization's consolidated gross revenues in the respective year in
          question during such period, or $200,000 in any year during such
          period, whichever is more; and

     o    has not been employed as an executive officer of any other entity
          whose Compensation Committee includes any of the Company's executive
          officers.

     The members of the Committee shall be elected by the Board and shall serve
on the Committee at the pleasure of the Board. The Board may designate a
Chairman of the Committee (the "Chairman"). In the absence of the Board's
appointment of a Chairman of the Committee, the members of the Committee shall
appoint a Chairman of the Committee by a majority vote of the full Committee.
The Committee shall conduct its affairs pursuant to and in accordance with the
applicable provisions in effect from time to time of the Nevada General
Corporation Law (Chapter 78 of the Nevada Revised Statutes) and the Articles of
Incorporation and Bylaws of the Company insofar as they relate to committees of
the Board.

   31



III. MEETINGS.

     The Committee shall use reasonable efforts to meet at least four (4) times
annually, and in any event shall meet at least three (3) times annually;
provided, however, that the Committee shall meet more frequently as
circumstances may make it appropriate. In order to ensure that the Committee
openly communicates with the Company's management personnel ("Management"), the
Company's independent accountants (the "Accountants") and the Company's internal
audit department personnel (the "Internal Audit Department"), the Committee
should meet at least annually with Management (including, without limitation,
the Company's Chief Executive Officer and Chief Financial Officer), the
Accountants and the Internal Audit Department to discuss any issues that the
Committee deems appropriate. Such meetings may take place at the regularly
scheduled Committee meeting and may be held collectively or separately, as the
Committee deems appropriate. To the extent that the Committee determines that it
would be appropriate to hold separate meetings with any of Management, the
Internal Audit Department or the Accountants, it shall do so. Minutes of each
meeting of the Committee shall be prepared at the direction of the Chairman and
shall be approved by the Committee at the subsequent Committee meeting. The
Secretary of the Company shall retain a copy of the Committee's minutes in the
Company's minute book.

IV.  RESPONSIBILITIES AND DUTIES.

     The Committee's specific responsibilities and duties shall include, without
limitation, the following:

     1.   Since the Accountants are ultimately accountable to the Committee and
          the Board, the Committee shall: (a) recommend to the Board the
          selection of the Accountants, considering independence, effectiveness
          and cost; (b) review the scope and extent of the Accountants' annual
          audit, including, without limitation, the terms of the Accountants'
          engagement letter and the compensation to be paid to the Accountants;
          and (c) review the performance of the Accountants on an annual basis
          and, if the circumstances warrant, recommend to the Board the
          termination of the Accountants (including with such recommendation the
          reasons for such proposed termination). In its review of the scope of
          the Accountant's annual audit, the Committee shall consider: (i) the
          industry and business risk characteristics of the Company; (ii) the
          Company's external reporting requirements; (iii) the materiality of
          the Company's various properties and business segments; (iv) the
          quality of internal accounting controls; and (v) the degree of
          involvement and reliability of the Internal Audit Department.

     2.   Each year, prior to the filing of the Company's Annual Report on Form
          10-K (the "Annual Report") with the Securities and Exchange Commission
          (the "SEC"), the Committee shall review with Management and the
          Accountants the Company's financial results. Such review shall
          include, without limitation, a review of, and discussion regarding:

          o    The financial information to be included in the Annual Report,
               including the financial statements, financial schedules,
               Management's Discussion and Analysis of Financial Condition and
               Results of Operations and all other financial disclosures
               required by generally accepted accounting principles ("GAAP") and
               the rules and regulations of the SEC as in effect from time to
               time;


                                      A-3
   32


          o    The Company's significant accounting policies, principles and
               practices and all material judgments made and accounting
               estimates used by Management in preparing the financial
               statements;

          o    Any significant disagreements between any of Management, the
               Internal Audit Department and the Accountants encountered during
               the course of the Company's annual audit or otherwise, and any
               limitations in scope or impediments to accessing information
               imposed on the Accountants or the Internal Audit Department by
               Management;

          o    Any significant adjustments to the Company's financial results
               that are or were proposed by the Accountants;

          o    Any significant variance between the Company's anticipated or
               forecasted results and the Company's actual results for the year;
               and

          o    Any other matters required to be discussed in accordance with
               Statement on Auditing Standards No. 61, as in effect from time to
               time ("SAS 61").

     3.   Each year, prior to the filing of the Company's Annual Report with the
          SEC, the Committee shall require the Accountants to submit a written
          report to the Committee: (a) delineating all relationships between the
          Accountants and the Company which, in the Accountants' professional
          judgment, may reasonably be thought to bear on its independence; and
          (b) confirming that, in the Accountants' professional judgment, it is
          independent of the Company within the meaning of the securities laws.
          The Committee shall review the Accountants' report and all material
          non-audit services provided by the Accountants, and shall discuss such
          report and services with the Accountants, to the extent necessary or
          appropriate to allow the Committee to make an informed conclusion with
          respect to whether the Accountants' services impair the Accountants'
          independence and objectivity required for the audit. The Committee
          shall recommend to the Board any actions the Committee believes are
          necessary or appropriate to ensure that the Accountants are, at all
          times, sufficiently independent and objective.

     4.   Based on the matters set forth in Items 2 and 3 above, the Committee
          shall recommend to the Board whether or not the financial information
          proposed to be included in the Annual Report should be so included.

     5.   Each year beginning in 2001, the Committee shall submit a report to
          the Company to be included in the Company's Proxy Statement covering
          all matters required to be covered by the rules and regulations of the
          SEC and any stock exchange or automated quotation system on which the
          Company's stock is listed, designated for trading or otherwise quoted,
          including without limitation, stating whether the Committee:

          o    Has reviewed and discussed the Company's audited financial
               statements with Management;

          o    Has discussed with the Accountants the matters required to be
               discussed by SAS 61;


                                      A-4
   33



          o    Has received the written disclosures and the letter from the
               Accountants required by Independence Standards Board Standard No.
               1, as in effect from time to time, and has discussed with the
               Accountants the Accountants' independence; and

          o    Based on the review and discussions set forth in Items 2 and 3
               above, the Committee has recommended to the Board that the
               audited financial statements should be included in the Annual
               Report for the last fiscal year for filing with the SEC.

     6.   The Committee or the Chairman shall meet (in person or by telephone)
          with the Company's Chief Financial Officer and the Accountants to
          review the Company's unaudited quarterly financial statements before
          the public release thereof. The Committee or the Chairman, as the case
          may be, shall discuss with the Company's Chief Financial Officer any
          significant variance between the Company's anticipated or forecasted
          results and the Company's actual results for the quarter. If the
          Chairman participates in any such meeting in lieu of the Committee,
          the Chairman shall report on such meeting to the Committee at the next
          Committee meeting.

     7.   The Committee shall, from time to time as it determines appropriate,
          consult with the Accountants, outside of the presence of Management,
          regarding the Company's internal controls and the accuracy and
          completeness of the Company's financial statements.

     8.   The Committee shall from time to time, but in no event less frequently
          than annually, review with Management the adequacy of the Company's
          system of internal controls for providing reasonable assurance that
          the Company's prescribed policies and procedures are followed and that
          transactions are properly recorded and reported.

     9.   The Committee shall review and approve all material changes to the
          Company's accounting policies, principles and practices ("Policies,
          Principles and Practices"), other than those required by law,
          regulation or GAAP, and shall review the extent to which all changes
          to Policies, Principles and Practices have been implemented (allowing
          an appropriate amount of time for the implementation thereof). In
          determining whether any material change to the Company's accounting
          policies, principles and practices is appropriate, the Committee shall
          consider the Accountants' judgment about the appropriateness thereof.

     10.  The Committee shall review and approve all material changes in the
          accounting, financial reporting or internal control-related duties of
          the Company's Chief Financial Officer.

     11.  The Committee shall review and approve recommendations from Management
          regarding the establishment of, or changes to, the respective job
          responsibilities of the staff members of the Internal Audit
          Department. The Committee shall review and approve the assignment by
          Management to any staff member of the Internal Audit Department of
          tasks outside the scope of such approved job responsibilities that may
          materially affect the ability of the Internal Audit Department to
          perform its assigned responsibilities.

     12.  At each of its meetings, the Committee shall review the activities of
          the Internal Audit Department and shall require that the policies and
          procedures followed by the Internal Audit Department adequately focus
          on significant risk areas to the Company.



                                      A-5

     13.  The Committee shall require that all Internal Audit Department
          personnel have unrestricted access to all relevant records, properties
          and other Company personnel.

     14.  The Committee shall review recommendations and reportable findings of
          the Internal Audit Department and the Accountants and require that
          appropriate actions are taken by Management in response to such
          recommendations and findings.

     15.  The Committee shall review significant accounting and reporting
          issues, including recent professional and regulatory pronouncements,
          and understand their impact on the Company's financial statements. The
          Committee shall require the Accountants to provide the Committee with
          periodic reports and supplementary materials to enable the Committee
          to perform this review.

     16.  The Committee shall, from time to time, review other matters that come
          to its attention in areas such as security and surveillance, legal and
          regulatory compliance, information technology systems, and other
          subject matters that could have a material impact on the Company's
          financial results and financial statements ("Other Subject Matters").
          In addition, the Committee shall meet at least annually with
          Management to assess generally the adequacy, from a financial
          reporting perspective, of the Company's policies and procedures and
          operations related to Other Subject Matters. The Committee shall
          recommend to Management or the Board any actions the Committee
          believes are necessary or appropriate to ensure that the Company's
          policies and procedures and operations relating to Other Subject
          Matters are adequate to provide effective internal controls.

     17.  The Committee shall review this Charter on an annual basis and shall
          recommend to the Board any amendments to this Charter that the
          Committee considers appropriate.

     The Committee shall, from time to time, perform any other activities
consistent with this Charter, the Company's Articles and By-laws and applicable
law as the Committee or the Board deems appropriate.

                             AMERISTAR CASINOS, INC.

                      1999 STOCK INCENTIVE PLAN, AS AMENDED

                       (EFFECTIVE AS OF DECEMBER 8, 2000)


     SECTION 1. Purposes.

     The purposes of the Ameristar Casinos, Inc. Amended and Restated 1999 Stock
Incentive Plan (the "Plan") are to (i) enable Ameristar Casinos, Inc. (the
"Company") and Related Companies (as defined below) to attract, motivate and
retain top-quality directors, officers, employees, consultants, advisers and
independent contractors (including without limitation dealers, distributors and
other business entities or persons providing services on behalf of the Company
or a Related Company), (ii) provide substantial incentives for such directors,
officers, employees, consultants, advisers and independent contractors of the
Company or a Related Company ("Participants") to act in the best interests of
the stockholders of the Company and (iii) reward extraordinary effort by
Participants on behalf of the Company or a Related Company. For purposes of the
Plan, a "Related Company" means any corporation, partnership, joint venture or
other entity in which the Company owns, directly or indirectly, at least a
twenty percent (20%) beneficial ownership interest.

     SECTION 2. Types of Awards. Awards under the Plan may be in the form of (i)
Stock Options or (ii) Restricted Stock.

     SECTION 3. Administration.

     3.1 Except as otherwise provided herein, the Plan shall be administered by
the Compensation Committee of the Board of Directors of the Company (the
"Board") or such other committee of directors as the Board shall designate,
which committee in either such case shall consist solely of not less than two
"non-employee directors" (as such term is defined in Rule 16b-3 under the
Securities Exchange Act of 1934 (the "Exchange Act") or any successor rule
("Rule 16b-3")) who shall serve at the pleasure of the Board, each of whom shall
also be an "outside director" within the meaning of Section 162(m) of the
Internal Revenue Code and Section 1.162-27 of the Treasury Regulations or any
successor provision(s) thereto ("Section 162(m)"); provided, however, that if
there are not two persons on the Board who meet the foregoing qualifications,
any such committee may be comprised of two or more directors of the Company,
none of which is an officer (other than a non-employee Chairman of the Board of
the Company) or an employee of the Company or a Related Company. If no such
committee has been appointed by the Board, the Plan shall be administered by the
Board, and the Plan shall be administered by the Board to the extent provided in
the last sentence of this Section. Such committee as shall be designated to
administer the Plan, if any, or the Board is referred to herein as the
"Committee." Notwithstanding any other provision of the Plan to the contrary, if
such a committee has been designated to administer the Plan, all actions with
respect to the administration of the Plan in respect of the members of such
committee shall be taken by the Board.




                                      B-1

     3.2 The Committee shall have the following authority with respect to awards
under the Plan to Participants: to grant awards to eligible Participants under
the Plan; to adopt, alter and repeal such administrative rules, guidelines and
practices governing the Plan as it shall deem advisable; to interpret the terms
and provisions of the Plan and any award granted under the Plan; and to
otherwise supervise the administration of the Plan. In particular, and without
limiting its authority and powers, the Committee shall have the authority:

          (a) to determine whether and to what extent any award or combination
     of awards will be granted hereunder;

          (b) to select the Participants to whom awards will be granted;

          (c) to determine the number of shares of the common stock of the
     Company, $0.01 par value (the "Stock"), to be covered by each award granted
     hereunder, provided that no Participant will be granted Stock Options on or
     with respect to more than 1,000,000 shares of Stock in any calendar year;

          (d) to determine the terms and conditions of any award granted
     hereunder, including, but not limited to, any vesting or other restrictions
     based on performance and such other factors as the Committee may determine,
     and to determine whether the terms and conditions of the award are
     satisfied;

          (e) to determine the treatment of awards upon a Participant's
     retirement, disability, death, termination for cause or other termination
     of employment or other qualifying relationship with the Company or a
     Related Company;

          (f) to determine that amounts equal to the amount of any dividends
     declared with respect to the number of shares covered by an award (i) will
     be paid to the Participant currently or (ii) will be deferred and deemed to
     be reinvested or (iii) will otherwise be credited to the Participant, or
     that the Participant has no rights with respect to such dividends;

          (g) to determine whether, to what extent, and under what circumstances
     Stock and other amounts payable with respect to an award will be deferred
     either automatically or at the election of a Participant, including
     providing for and determining the amount (if any) of deemed earnings on any
     deferred amount during any deferral period;

          (h) to provide that the shares of Stock received as a result of an
     award shall be subject to a right of first refusal, pursuant to which the
     Participant shall be required to offer to the Company any shares that the
     Participant wishes to sell, subject to such terms and conditions as the
     Committee may specify;

          (i) to amend the terms of any award, prospectively or retroactively;
     provided, however, that no amendment shall impair the rights of the award
     holder without his or her consent; and




                                      B-2
   37


          (j) to substitute new Stock Options for previously granted Stock
     Options, or for options granted under other plans, in each case including
     previously granted options having higher option prices.

     3.3 All determinations made by the Committee pursuant to the provisions of
the Plan shall be final and binding on all persons, including the Company and
all Participants.

     3.4 The Committee may from time to time delegate to one or more officers of
the Company any or all of its authorities granted hereunder except with respect
to awards granted to persons subject to Section 16 of the Exchange Act. The
Committee shall specify the maximum number of shares that the officer or
officers to whom such authority is delegated may award, and the Committee may in
its discretion specify any other limitations or restrictions on the authority
delegated to such officer or officers.

     SECTION 4. Stock Subject to Plan.

     4.1 The total number of shares of Stock reserved and available for
distribution under the Plan shall be 4,600,000 (subject to adjustment as
provided in Section 4.3); provided, however, that no award of a Stock Option or
Restricted Stock may be made at any time if, after giving effect to such award,
(i) the total number of shares of Stock issued upon the exercise of options
under the Plan and the Company's Management Stock Option Incentive Plan, as
amended and restated through September 4, 1996 (the "Prior Plan") plus (ii) the
total number of shares of Stock issuable upon exercise of all outstanding
options of the Company under the Plan and the Prior Plan plus (iii) the total
number of shares of Stock underlying awards of Restricted Stock under the Plan
(whether or not the applicable restrictions have lapsed) would exceed 4,600,000
shares (subject to adjustment as provided in Section 4.3). Shares of Stock
issuable in connection with any award under the Plan may consist of authorized
but unissued shares or treasury shares.

     4.2 To the extent a Stock Option terminates without having been exercised,
or shares awarded are forfeited, the shares subject to such award shall again be
available for distribution in connection with future awards under the Plan,
subject to the limitations set forth in Section 4.1, unless the forfeiting
Participant received any benefits of ownership such as dividends from the
forfeited award.

     4.3 In the event of any merger, reorganization, consolidation, sale of
substantially all assets, recapitalization, Stock dividend, Stock split,
spin-off, split-up, split-off, distribution of assets or other change in
corporate structure affecting the Stock, a substitution or adjustment, as may be
determined to be appropriate by the Committee in its sole discretion, shall be
made in the aggregate number of shares reserved for issuance under the Plan, the
number of shares subject to outstanding awards and the amounts to be paid by
award holders or the Company, as the case may be, with respect to outstanding
awards; provided, however, that no such adjustment shall increase the aggregate
value of any outstanding award. In the event any change described in this
Section 4.3 occurs and an adjustment is made in the outstanding Stock Options, a
similar adjustment shall be made in the maximum number of shares covered by
Stock Options that may be granted to any employee pursuant to Section 3.2(c).

     SECTION 5. Eligibility.

     Participants under the Plan shall be selected from time to time by the
Committee, in its sole discretion, from among those eligible.




                                      B-3

     SECTION 6. Stock Options.

     6.1 The Stock Options awarded to officers and employees under the Plan may
be of two types: (i) Incentive Stock Options within the meaning of Section 422
of the Internal Revenue Code or any successor provision thereto ("Section 422");
and (ii) Non-Qualified Stock Options. If any Stock Option does not qualify as an
Incentive Stock Option, or the Committee at the time of grant determines that
any Stock Option shall be a Non-Qualified Stock Option, it shall constitute a
Non-Qualified Stock Option. Stock Options awarded to any Participant who is not
an officer or employee of the Company or a Related Company shall be
Non-Qualified Stock Options.

     6.2 Subject to the following provisions, Stock Options awarded to
Participants under the Plan shall be in such form and shall have such terms and
conditions as the Committee may determine:

          (a) Option Price. The option price per share of Stock purchasable
     under a Stock Option shall be determined by the Committee.

          (b) Option Term. The term of each Stock Option shall be fixed by the
     Committee, but in no event longer than one hundred twenty (120) months
     after the date of grant of such Stock Option.

          (c) Exercisability. Stock Options shall be exercisable at such time or
     times and subject to such terms and conditions as shall be determined by
     the Committee. If the Committee provides that any Stock Option is
     exercisable only in installments, the Committee may waive such installment
     exercise provisions at any time in whole or in part.

          (d) Method of Exercise. Stock Options may be exercised in whole or in
     part at any time during the option period by giving written notice of
     exercise to the Company specifying the number of shares to be purchased,
     accompanied by payment of the purchase price. Payment of the purchase price
     shall be made in such manner as the Committee may provide in the award,
     which may include cash (including cash equivalents), delivery of shares of
     Stock acceptable to the Committee already owned by the optionee or subject
     to awards hereunder, any other manner permitted by law as determined by the
     Committee, or any combination of the foregoing. The Committee may provide
     that all or part of the shares received upon the exercise of a Stock Option
     which are paid for using Restricted Stock shall be restricted in accordance
     with the original terms of the award in question.

          (e) No Stockholder Rights. An optionee shall have no rights to
     dividends or other rights of a stockholder with respect to shares subject
     to a Stock Option until the optionee has given written notice of exercise
     and has paid for such shares.

          (f) Surrender Rights. The Committee may provide that Stock Options may
     be surrendered for cash upon any terms and conditions set by the Committee.

          (g) Non-Transferability; Limited Transferability. A Stock Option
     Agreement may permit an optionee to transfer the Stock Option to his or her
     children, grandchildren or spouse ("Immediate Family"), to one or more
     trusts for the benefit of such Immediate Family members, or to one or more
     partnerships or limited liability companies in which such Immediate Family



                                      B-4
   39



     members are the only partners or members if (i) the agreement setting forth
     such Stock Option expressly provides that such Stock Option may be
     transferred only with the express written consent of the Committee, and
     (ii) the optionee does not receive any consideration in any form whatsoever
     for such transfer other than the receipt of an interest in the trust,
     partnership or limited liability company to which the non-qualified option
     is transferred. Any Stock Option so transferred shall continue to be
     subject to the same terms and conditions as were applicable to such Stock
     Option immediately prior to the transfer thereof. Any Stock Option not (x)
     granted pursuant to any agreement expressly allowing the transfer of such
     Stock Option or (y) amended expressly to permit its transfer shall not be
     transferable by the optionee otherwise than by will or by the laws of
     descent and distribution, and such Stock Option shall be exercisable during
     the optionee's lifetime only by the optionee.

          (h) Termination of Relationship. If an optionee's employment or other
     qualifying relationship with the Company or a Related Company terminates by
     reason of death, disability, retirement, voluntary or involuntary
     termination or otherwise, the Stock Option shall be exercisable to the
     extent determined by the Committee; provided, however, that unless
     employment or such other qualifying relationship is terminated for cause
     (as may be defined by the Committee in connection with the grant of any
     Stock Option), the Stock Option shall remain exercisable (to the extent
     that it was otherwise exercisable on the date of termination) for (A) at
     least six (6) months from the date of termination if termination was caused
     by death or disability or (B) at least ninety (90) days from the date of
     termination if termination was caused by other than death or disability.
     The Committee may provide that, notwithstanding the option term fixed
     pursuant to Section 6.2(b), a Stock Option which is outstanding on the date
     of an optionee's death shall remain outstanding for an additional period
     after the date of such death.

          (i) Option Grants to Participants Subject to Section 16. If for any
     reason any Stock Option granted to a Participant subject to Section 16 of
     the Exchange Act is not approved in the manner provided for in clause
     (d)(1) or (d)(2) of Rule 16b-3, neither the Stock Option (except upon its
     exercise) nor the Stock underlying the Stock Option may be disposed of by
     the Participant until six months have elapsed following the date of grant
     of the Stock Option, unless the Committee otherwise specifically permits
     such disposition.

     6.3 Notwithstanding the provisions of Section 6.2, no Incentive Stock
Option shall (i) have an option price which is less than one hundred percent
(100%) of the Fair Market Value (as defined below) of the Stock on the date of
the award of the Stock Option (or less than one hundred ten percent (110%) of
the Fair Market Value of the Stock on the date of award of the Stock Option if
the Participant owns, or would be considered to own by reason of Section 424(d)
of the Internal Revenue Code or any successor provision thereto, more than ten
percent (10%) of the total combined voting power of all classes of stock of the
Company or any parent or subsidiary of the Company at the time of the grant of
the Stock Option), (ii) be exercisable more than ten (10) years after the date
such Incentive Stock Option is awarded (five (5) years after the date of award
if the Participant owns, or would be considered to own by reason of Section
424(d) of the Internal Revenue Code or any successor provision thereto, more
than ten percent (10%) of the total combined voting power of all classes of
stock of the Company or any parent or subsidiary of the Company at the time of
the grant of the Stock Option), (iii) be awarded more than ten (10) years after
the effective date of the Plan (or the latest restatement of the Plan) or (iv)
be transferable other than by will or by the laws of descent and distribution.
In addition, the aggregate Fair Market Value (determined as of the time a Stock
Option is granted) of Stock with respect to


                                      B-5
   40


which Incentive Stock Options granted after December 31, 1986 are exercisable
for the first time by a Participant in any calendar year (under the Plan and any
other plans of the Company or any subsidiary or parent corporation) shall not
exceed $100,000. For purposes of the Plan, "Fair Market Value" in relation to a
share of the Stock means, if the Stock is publicly traded, the mean between the
highest and lowest quoted selling prices of the Common Stock on such date or, if
not available, the mean between the bona fide bid and asked prices of the Common
Stock on such date. In any situation not covered above, the Fair Market Value
shall be determined by the Committee in accordance with one of the valuation
methods described in Section 20.2031-2 of the Federal Estate Tax Regulations (or
any successor provision thereto).

     SECTION 7. Restricted Stock.

     Subject to the following provisions, all awards of Restricted Stock to
Participants shall be in such form and shall have such terms and conditions as
the Committee may determine:

          (a) The Restricted Stock award shall specify the number of shares of
     Restricted Stock to be awarded, the price, if any, to be paid by the
     recipient of the Restricted Stock and the date or dates on which, or the
     conditions upon the satisfaction of which, the Restricted Stock will vest.
     The vesting of Restricted Stock may be conditioned upon the completion of a
     specified period of service with the Company or a Related Company, upon the
     attainment of specified performance goals or upon such other criteria as
     the Committee may determine.

          (b) Stock certificates representing the Restricted Stock awarded to an
     employee shall be registered in the Participant's name, but the Committee
     may direct that such certificates be held by the Company on behalf of the
     Participant. Except as may be permitted by the Committee, no share of
     Restricted Stock may be sold, transferred, assigned, pledged or otherwise
     encumbered by the Participant until such share has vested in accordance
     with the terms of the Restricted Stock award. At the time Restricted Stock
     vests, a certificate for such vested shares shall be delivered to the
     Participant (or his or her designated beneficiary in the event of death),
     free of all restrictions.

          (c) The Committee may provide that the Participant shall have the
     right to vote or receive dividends, or both, on Restricted Stock. The
     Committee may provide that Stock received as a dividend on, or in
     connection with a stock split of, Restricted Stock shall be subject to the
     same restrictions as the Restricted Stock.

          (d) Except as may be provided by the Committee, in the event of a
     Participant's termination of employment or other qualifying relationship
     with the Company or a Related Company before all of his or her Restricted
     Stock has vested, or in the event any conditions to the vesting of
     Restricted Stock have not been satisfied prior to any deadline for the
     satisfaction of such conditions set forth in the award, the shares of
     Restricted Stock which have not vested shall be forfeited, and the
     Committee may provide that the lower of (i) any purchase price paid by the
     Participant and (ii) the Restricted Stock's aggregate Fair Market Value on
     the date of forfeiture shall be paid in cash to the Participant.

          (e) The Committee may waive, in whole or in part, any or all of the
     conditions to receipt of, or restrictions with respect to, any or all of
     the Participant's Restricted Stock.




                                      B-6
   41


          (f) If for any reason any Restricted Stock awarded to a Participant
     subject to Section 16 of the Exchange Act is not approved in the manner
     provided for in clause (d)(1) or (d)(2) of Rule 16b-3, the Restricted Stock
     may not be disposed of by the Participant until six months have elapsed
     following the date of award of the Restricted Stock, unless the Committee
     otherwise specifically permits such disposition.

     SECTION 8. Election to Defer Awards.

     The Committee may permit a Participant to elect to defer receipt of an
award for a specified period or until a specified event, upon such terms as are
determined by the Committee.

     SECTION 9. Tax Withholding.

     9.1 Each Participant shall, no later than the date as of which the value of
an award first becomes includible in such person's gross income for applicable
tax purposes, pay to the Company, or make arrangements satisfactory to the
Committee (which may include delivery of shares of Stock already owned by the
optionee or subject to awards hereunder) regarding payment of, any federal,
state, local or other taxes of any kind required by law to be withheld with
respect to the award. The obligations of the Company under the Plan shall be
conditional on such payment or arrangements, and the Company (and, where
applicable, any Related Company), shall, to the extent permitted by law, have
the right to deduct any such taxes from any payment of any kind otherwise due to
the Participant.

     9.2 To the extent permitted by the Committee, and subject to such terms and
conditions as the Committee may provide, a Participant may elect to have the
withholding tax obligation, or any additional tax obligation with respect to any
awards hereunder, satisfied by (i) having the Company withhold shares of Stock
otherwise deliverable to such person with respect to the award or (ii)
delivering to the Company shares of unrestricted Stock.

     SECTION 10. Amendments and Termination.

     No awards may be granted under the Plan more than ten (10) years after the
date of approval of the Plan by the stockholders of the Company. The Board may
discontinue the Plan at any earlier time and may amend it from time to time. No
amendment or discontinuation of the Plan shall adversely affect any award
previously granted without the award holder's written consent. Amendments may be
made without stockholder approval except (i) if and to the extent necessary to
satisfy any applicable mandatory legal or regulatory requirements (including the
requirements of any stock exchange or over-the-counter market on which the Stock
is listed or qualified for trading and any requirements imposed under any state
securities laws or regulations as a condition to the registration of securities
distributable under the Plan or otherwise), or (ii) as required for the Plan to
satisfy the requirements of Section 162(m), Section 422 or any other
non-mandatory legal or regulatory requirements if the Board of Directors deems
it desirable for the Plan to satisfy any such requirements.

     SECTION 11. Acceleration of Vesting in Certain Circumstances.

     Notwithstanding any other provision of the Plan, upon the dissolution or
liquidation of the Company or upon any reorganization, merger or consolidation
with one or more corporations or other entities as a result of which the Company
is not the surviving entity, or upon a sale of all or substantially all of the
assets of the Company to another corporation or entity, the Committee may take
such action, if any, as it in its discretion may



                                      B-7
   42



deem appropriate: (i) to accelerate the time within which and the extent to
which Options may be exercised, to terminate Options at or prior to the date of
any such event or to provide for the assumption of Options by surviving,
consolidated, successor or transferee corporations or entities; or (ii) to waive
any restrictions applicable to any outstanding Restricted Stock awards under the
Plan, following which such shares shall be deemed fully vested, or to provide
that any securities or other consideration issuable to the Participant in
respect of such Restricted Stock by the surviving, consolidated, successor or
transferee corporations or entities shall remain subject to the restrictions
applicable to such Restricted Stock award.

     SECTION 12. General Provisions.

     12.1 If the granting of any award under the Plan or the issuance, purchase
or delivery of Stock thereunder shall require, in the determination of the
Committee from time to time and at any time, (i) the listing, registration or
qualification of the Stock subject or related thereto upon any securities
exchange or over-the-counter market or under any federal or state law or (ii)
the consent or approval of any government regulatory body, then any such award
shall not be granted or exercised, in whole or in part, unless such listing,
registration, qualification, consent or approval shall have been effected or
obtained on conditions, if any, as shall be acceptable to the Committee. In
addition, in connection with the granting or exercising of any award under the
Plan, the Committee may require the recipient to agree not to dispose of any
Stock issuable in connection with such award, except upon the satisfaction of
specified conditions, if the Committee determines such agreement is necessary or
desirable in connection with any requirement or interpretation of any federal or
state securities law, rule or regulation.

     12.2 Nothing set forth in this Plan shall prevent the Board from adopting
other or additional compensation arrangements. Neither the adoption of the Plan
nor any award hereunder shall confer upon any employee of the Company, or of a
Related Company, any right to continued employment, and no award under the Plan
shall confer upon any director any right to continued service as a director.

     12.3 Determinations by the Committee under the Plan relating to the form,
amount, and terms and conditions of awards need not be uniform, and may be made
selectively among persons who receive or are eligible to receive awards under
the Plan, whether or not such persons are similarly situated.

     12.4 No member of the Board or the Committee, nor any officer or employee
of the Company acting on behalf of the Board or the Committee, shall be
personally liable for any action, determination or interpretation taken or made
with respect to the Plan, and all members of the Board or the Committee and all
officers or employees of the Company acting on their behalf shall, to the extent
permitted by law, be fully indemnified and protected by the Company in respect
of any such action, determination or interpretation.

     SECTION 13. Effective Date of Plan.

     The Plan shall be effective upon the approval of the Plan by (i) the Board
of Directors of the Company and (ii) the stockholders of the Company acting by a
majority of the votes cast at a duly held meeting of stockholders at which a
quorum representing at least a majority of the outstanding shares is, either in
person or by proxy, present and voting on the Plan.

     The Plan was duly approved by the Board of Directors of the Company on
December 8, 2000.
