                             INFORMATION STATEMENT
   
   This Information Statement is furnished to holders of record of the common
stock, $.01 par value per share, of MGM Grand, Inc., a Delaware corporation, as
of February 5, 1999, pursuant to Section 14(c) of the Securities Exchange Act
of 1934, as amended, and Rule 14c-2 thereunder. The purpose of this Information
Statement is to inform all stockholders of the approval of the MGM Grand, Inc.
Replacement Stock Option Plan and the MGM Grand, Inc. Directors' Replacement
Stock Option Plan. These plans were adopted by MGM Grand in connection with its
acquisition of Primadonna Resorts, Inc. which is expected to be completed the
first quarter of 1999. This Information Statement was first mailed or delivered
to MGM Grand's stockholders on or about February 5, 1999.     
 
   We are not asking you for a proxy and you are requested not to send us a
proxy.
   
   This Information Statement is being furnished to stockholders solely to
provide them with certain information concerning the replacement stock option
plan and the directors' replacement stock option plan in accordance with the
requirements of the Securities Exchange Act of 1934, as amended, and the rules
and regulations adopted thereunder, including particularly Regulation 14C. We
are not seeking consent, authorization or proxies from our stockholders, as the
consent of stockholders entitled to cast the required number of votes to
approve these plans has been obtained pursuant to Section 228 of the Delaware
General Corporation Law. The plans will not become effective pursuant to the
written consent already obtained until 20 days after this Information Statement
is mailed to stockholders. This Information Statement also serves as notice to
stockholders of an action taken by less than unanimous written consent as
required by Section 228. Section 228 permits MGM Grand to take the action
approving the plans without a meeting of the stockholders if the written
consent by holders having not less than the minimum number of votes that would
be required to authorize or take such action at a meeting at which all shares
entitled to vote thereon were present and voted. The reported closing price of
the Company's common stock on the New York Stock Exchange on February 3, 1999
was $30.63.     
 
                      DESCRIPTION OF THE PRIMADONNA MERGER
 
   Pursuant to an agreement and plan of merger, dated as of December 2, 1998,
MGM Grand and Primadonna have agreed on a merger of MGM Grand and Primadonna.
In the merger, a subsidiary of MGM Grand will merge into Primadonna, and
Primadonna will become a wholly owned subsidiary of MGM Grand. Each stockholder
of Primadonna will be entitled to receive .33 shares of MGM Grand common stock
for each share of Primadonna common stock held. The merger will not have any
effect on the MGM Grand common shares that MGM Grand stockholders currently
own. Of course, the number of outstanding shares of MGM Grand common stock will
increase from approximately 52 million shares to 61.5 million shares because of
the MGM Grand common stock to be issued to Primadonna's stockholders in
connection with the merger.

 
   While holders of a majority of Primadonna's outstanding common stock need to
approve the merger, the approval of MGM Grand's stockholders is not required in
order to complete the merger. A special meeting of Primadonna's stockholders
has been scheduled for February 23, 1999. Holders of approximately 53% of the
outstanding Primadonna common stock have given support letters to MGM Grand in
which they agree to vote to approve the merger agreement. Thus, the merger
agreement will be approved at the Primadonna stockholders meeting. MGM Grand's
board of directors will not be changed as a result of the merger. However, MGM
Grand will invite Gary E. Primm, Chairman of the Board and Chief Executive
Officer of Primadonna, to join its board of directors upon his approval by the
relevant gaming authorities. We expect that the executive officers of MGM Grand
will continue as the executive officers of MGM Grand after the merger.
   
   Under the merger agreement, on the closing of the merger, each outstanding
option to purchase Primadonna common stock previously granted by Primadonna or
its subsidiaries will be converted into an option to acquire the number of
shares of MGM Grand common stock, rounded down to the nearest whole share,
determined by multiplying the number of shares of Primadonna common stock
subject to such option by .33, the merger conversion ratio. The exercise price
per share of MGM Grand common stock subject to the replacement option shall be
equal to the exercise price per share of Primadonna common stock subject to the
relevant Primadonna option divided by .33 and then rounded up to the nearest
whole cent. Under the terms of the Primadonna options, the closing of the
merger will have the effect of causing unvested Primadonna options, other than
options granted under Primadonna's 1993 Directors' Stock Incentive Plan, to
accelerate and vest. MGM Grand has agreed to adopt, subject to the consent of
MGM Grand stockholders, stock option plans substantially similar to the
existing Primadonna plans prior to completion of the merger. Copies of the new
plans adopted by MGM Grand pursuant to which it will grant replacement options
to Primadonna option holders are attached as Appendices A and B to this
Information Statement and are incorporated herein by this reference. Tracinda
Corporation, holder of approximately 65.6% of the outstanding MGM Grand common
stock, has consented to the adoption of the new option plans, which are
substantially similar to the existing Primadonna option plans. The sole purpose
of the new MGM Grand option plans is to provide replacement options to
Primadonna option holders.     
 
                        DESCRIPTION OF THE OPTION PLANS
 
Replacement Stock Option Plan Summary
 
   Administration. The replacement option plan will be administered by the
compensation committee of MGM Grand's board (James D. Aljian, Fred Benninger
and Jerome B. York). The compensation committee may permit any recipient of an
option to pay the purchase price of the common stock issuable pursuant to the
option in any lawful manner and for any lawful consideration that the
compensation committee approves.
   
   The replacement option plan provides for the grant of options to replace
options previously granted under Primadonna's stock incentive plan. MGM Grand
intends that each option that replaces an incentive stock option ("ISO") shall
be an ISO that qualifies under Section 424(a) of the Internal Revenue Code of
1986, as amended, as a substitution and shall not be a modification under Code
Section 424(h).     
 
                                       2

 
   The maximum number of shares of MGM Grand common stock authorized for
issuance under the replacement option plan is 704,259. The plan expires in
April 2003. No options may be granted after such expiration, but options
granted under the plan may continue to be exercised after that date in
accordance with their terms. In addition, options may be amended after that
date, so long as there is no increase in the number of shares subject to or
comprising the option. Options may be reduced by the amount necessary to
satisfy any applicable tax withholding requirements imposed on MGM Grand in
respect of the option. Shares of common stock reserved for options that
terminate, expire or are cancelled (and thus are not exercised) will not be
available for future grant under this plan.
 
   In the event of a stock split, the declaration of a stock dividend, the
exchange or conversion of securities of the class subject to an option into
cash, property or different kinds of securities pursuant to a merger,
reorganization or otherwise, or the sale of substantially all of the assets of
MGM Grand or if an extraordinary dividend is declared, adjustments will be made
in (i) the number and type of shares or other securities or cash or other
property that may be acquired pursuant to each option and (ii) any other terms
as are necessarily affected by such event.
 
   Amendments. The MGM Grand board of directors may amend or terminate the plan
at any time, but may not unilaterally change or affect any outstanding option
that would deprive the holder of any of the material benefits thereunder.
Termination of the replacement option plan would have no effect on outstanding
options.
 
   Eligibility. Holders of Primadonna options granted under Primadonna's
Amended and Restated 1993 Incentive Stock Plan at the effective time of the
merger are the only persons eligible to receive options under this plan.
Approximately 64 persons are eligible to participate in this plan.
 
   Non-Transferability. Generally, options under the plan are not transferable
by a holder other than by will or the laws of descent and distribution and are
generally exercisable, during his or her lifetime, only by the holder; and the
shares issuable pursuant to an option will be paid only to the holder or the
holder's beneficiary or representative. However, the compensation committee may
establish conditions and procedures (for example, in connection with a holder's
estate or tax planning initiatives) under which options may be transferred to a
third party, to the extent permitted by law.
 
   Other Information. The replacement option plan is not exclusive. Options may
also be awarded to eligible persons pursuant to other incentive plans or
without reference to a plan as from time to time authorized by MGM Grand.
 
Directors' Replacement Stock Option Plan Summary
 
   Administration. The directors' replacement option plan will be administered
by the compensation committee of MGM Grand's board. The compensation committee
may permit any recipient of an option to pay the purchase price of the common
stock issuable pursuant to the option in any lawful manner and for any lawful
consideration that the compensation committee approves.
 
   The maximum number of shares of MGM Grand common stock authorized for
issuance under the directors' replacement option plan is 31,845. The plan
expires in April 2003. No options may be granted after such expiration, but
options granted under the plan may continue to be exercised after
 
                                       3

 
that date in accordance with their terms. In addition, options may be amended
after that date, so long as there is no increase in the number of shares
subject to or comprising the option. Options may be reduced by the amount
necessary to satisfy any applicable tax withholding requirements imposed on
MGM Grand in respect of the option. Shares of common stock reserved for options
that terminate, expire or are cancelled (and thus are not exercised) will not
be available for future grant under this plan.
 
   In the event of a stock split, the declaration of a stock dividend, the
exchange or conversion of securities of the class subject to an option into
cash, property or different kinds of securities pursuant to a merger,
reorganization or otherwise, or the sale of substantially all of the assets of
MGM Grand or if an extraordinary dividend is declared, adjustments will be made
in (i) the number and type of shares or other securities or cash or other
property that may be acquired pursuant to each option and (ii) any other terms
as are necessarily affected by such event.
 
   Amendments. The MGM Grand board of directors may amend or terminate the plan
at any time, but may not unilaterally change or affect any outstanding option
that would deprive the holder of any of the material benefits thereunder.
Termination of the directors' replacement option plan would have no effect on
outstanding options.
 
   Eligibility. Holders of Primadonna options granted under Primadonna's 1993
Directors' Stock Option Plan at the effective time of the merger are the only
persons eligible to receive options under this plan. Approximately 4 persons
are eligible to participate in this plan.
 
   Non-Transferability. Generally, options under the plan are not transferable
by a holder other than by will or the laws of descent and distribution and are
generally exercisable, during his or her lifetime, only by the holder; and the
shares issuable pursuant to an option will be paid only to the holder or the
holder's beneficiary or representative. However, the compensation committee may
establish conditions and procedures (for example, in connection with a holder's
estate or tax planning initiatives) under which options may be transferred to a
third party, to the extent permitted by law.
 
   Other Information. The director's replacement option plan is not exclusive.
Options may also be awarded to eligible persons pursuant to other incentive
plans or without reference to a plan as from time to time authorized by MGM
Grand.
 
       FEDERAL INCOME TAX TREATMENT OF OPTIONS UNDER THE NEW OPTION PLANS
 
   Certain of the federal income tax consequences to optionees and MGM Grand of
options granted under the new plans should generally be as set forth in the
following summary.
   
   A person to whom an ISO is granted will not recognize income at the time of
grant or exercise of such option. However, upon the exercise of an ISO, any
excess in the fair market price of the common stock over the option price
constitutes a tax preference item that may have alternative minimum tax
consequences for the holder. If the holder sells such shares more than one year
after the date of transfer of such shares and more than two years after the
date of grant of such ISO, the holder will generally recognize a long-term
capital gain or loss equal to the difference, if any, between the sale prices
of such shares and the option price.     
 
                                       4

 
   
   For each nonqualified stock option replacement, generally a person to whom
an option is granted will not recognize income at the time of grant of such
option. When the holder exercises such option, the holder will recognize
ordinary income equal to the excess, if any, of the fair market value, as of
the date of the option exercise, of the shares that the holder receives upon
such exercise over the option price paid, and the holder's holding period for
such shares will commence on the date on which the holder recognizes taxable
income in respect of such shares. Gain or loss upon a subsequent sale of any
MGM Grand common stock received upon the exercise of an option generally would
be taxed as capital gain or loss (long-term or short-term depending upon the
holding period of the stock sold). Certain additional rules apply if the holder
pays the option price in shares previously owned by the holder.     
   
   MGM Grand is generally entitled to deduct an amount equal to the difference
between the option exercise price and the fair market value of the shares at
the time of exercise of a nonqualified option. MGM Grand is generally not
entitled to a similar deduction either upon grant or exercise of an ISO. If ISO
shares are not held for specified qualifying periods, however, the difference
between the fair market value of the shares at the date of exercise (or, if
lower, the sale price) and the cost of such shares is taxed as ordinary income
(and MGM Grand will receive a corresponding deduction) in the year the shares
are sold.     
 
                               SPECIFIC BENEFITS
 
   The number, amount and type of options to be received by eligible persons
under the new option plans will be determined by the number, amount and type of
Primadonna options outstanding at the effective time of the merger of MGM Grand
and Primadonna. No officers or directors of MGM Grand will receive any options
under either of the new option plans. Gary E. Primm, Chairman of the Board and
Chief Executive Officer of Primadonna, is to be invited to join the MGM Grand
board after receipt of all required gaming approvals. Upon completion of the
merger, his Primadonna options will be replaced with options to purchase 72,600
shares of MGM Grand common stock. Such options will have no dollar value based
upon the $30.875 per share closing price of MGM Grand stock on January 27,
1999.
 
                   MATTERS REGARDING THE STOCKHOLDER APPROVAL
   
   As of February 5 , 1999, the date on which holders of majority of MGM
Grand's common stock approved the new option plans by written consent, there
were outstanding 52,033,097 shares of common stock, and MGM Grand had received
the written consent approving the new option plans from Tracinda Corporation,
its principal stockholder, representing 34,110,716 shares of common stock or
approximately 65.6% of the outstanding shares. Information with respect to the
beneficial ownership of MGM Grand's common stock is set forth in Appendix C and
incorporated herein by reference.

                                                                      APPENDIX A
                                MGM GRAND, INC.
 
                         REPLACEMENT STOCK OPTION PLAN
   
   1. PURPOSE OF PLAN. The purpose of this Replacement Stock Option Plan
(referred to herein as the "PLAN") of MGM Grand, Inc., a Delaware corporation
(the "COMPANY"), is to enable the Company to grant options to replace
outstanding options previously granted by Primadonna Resorts, Inc., a Nevada
corporation ("PRIMADONNA"), in accordance with that certain Agreement and Plan
of Merger, dated as of December 2, 1998, by and among the Company, MGM Grand
Acquisition Corp. and Primadonna (the "MERGER AGREEMENT"). Pursuant to the
Merger Agreement, MGM Grand Acquisition Corp. will be merged into Primadonna,
and Primadonna will become a wholly owned subsidiary of the Company (the
"MERGER").     
 
   2. PERSONS ELIGIBLE UNDER PLAN. Any individual person who holds options to
purchase Primadonna common stock granted under Primadonna's Amended and
Restated 1993 Incentive Plan ("Primadonna Options") shall be eligible for the
grant of an option or options under this Plan ("ELIGIBLE PERSON").
 
   3. STOCK SUBJECT TO PLAN.
   
   (a) Incentive Stock Option Limit. The maximum number of shares of the
Company's Common Stock, $.01 par value per share (the "COMMON SHARES"), that
may be issued pursuant to options granted under this Plan and qualified as
incentive stock options ("ISOs") under Section 422 of the Internal Revenue Code
of 1986, as amended (the "CODE"), is 704,259, subject to adjustment as provided
in or pursuant to Section 6. It is the intent of the Company that each ISO
under the Plan shall qualify under Code Section 424(a) as a substitution and
shall not be a modification under Code Section 424(h). Each ISO shall be
interpreted and administered accordingly.     
   
   (b) Aggregate Share Limits. The maximum number of shares of Common Shares
that may be issued pursuant to all options (including ISOs) granted under this
Plan is 704,259, subject to adjustment as provided in or pursuant to Section 6,
and such maximum number, as so adjusted, shall be referred to as the "SHARE
LIMIT." Common Shares subject to outstanding Options shall be reserved for
issuance. If any Option shall expire or be canceled or terminated without
having been exercised in full, the undelivered Common Shares subject thereto
shall cease to be available for the purposes of this Plan.     
 
   4. ADMINISTRATION OF PLAN.
 
   (a) The Committee. This Plan shall be, to the maximum extent possible, self-
effectuating. This Plan shall be interpreted and, to the extent any
determinations are required hereunder, shall be administered by a committee
(the "COMMITTEE") of the entire Board of Directors of the Company (the "BOARD")
or a committee consisting of two or more directors designated by the Board for
this purpose.
 
   (b) Binding Determinations. Any action taken by, or inaction of, the
Company, the Board or the Committee relating or pursuant to this Plan shall be
within the absolute discretion of that entity or body and shall be conclusive
and binding upon all persons. No member of the Board or officer of the
 
                                      A-1

 
Company shall be liable for any such action or inaction of the entity or body,
of another person or, except in circumstances involving such person's bad
faith.
 
   (c) Reliance On Experts. In making any determination or in taking or not
taking any action under this Plan, the Board and the Committee may obtain and
may rely upon the advice of experts, including professional advisors to the
Company. No director, officer or agent of the Company shall be liable for any
such action or determination taken or made or omitted in good faith.
 
   (d) Delegation. The Committee may delegate ministerial, non-discretionary
functions to individuals who are officers or employees of the Company.
 
   5. OPTIONS.
   
   (a) Option Grants. Subject to adjustments contemplated by Section 6(a), each
holder of a Primadonna Option upon consummation of the Merger shall be granted
an option to purchase that number of Common Shares which is the product of (y)
the number of shares of Primadonna's common stock subject to the holder's
Primadonna Option and (z) .33, the conversion ratio pursuant to the Merger
Agreement.     
 
   (b) Option Agreements. The Committee may authorize any officer (other than
the particular recipient) to execute any or all agreements memorializing any
grant of an option by the Committee under this Plan. All options shall be
evidenced by a writing executed on behalf of the Company (the "OPTION
AGREEMENT") and, if required by the Committee, by the recipient of the option.
 
   (c) Price; Consideration. The purchase price per Common Share covered by
each Option shall be determined by dividing the option price of the Primadonna
Option it replaces by .33 and rounding up to the nearest whole cent. Common
Shares may be issued pursuant to an Option for any lawful consideration as
determined by the Committee, including, without limitation, services rendered
by the recipient of such Option, but shall not be issued for less than the
minimum lawful consideration.
   
   (d) Term and Vesting. The terms and conditions of each option shall be the
same as those of the Primadonna Option it replaces, after adjustment to take
into account the .33 conversion ratio pursuant to the Merger Agreement provided
herein.     
   
   (e) Loans. The Committee shall have the express authority to make or
authorize loans to finance, or to otherwise accommodate the financing of, the
acquisition or exercise of an option, subject to Section 10(a).     
 
   (f) Transfer Restrictions.
     
       (i) Limit on Exercise and Transfer. Unless otherwise expressly
  provided in (or pursuant to) this Section 5(e), by applicable law or by the
  applicable Option Agreement: (A) all options are non-transferable and shall
  not be subject in any manner to sale, transfer, anticipation, alienation,
  assignment, pledge, encumbrance or charge; (B) options shall be exercised
  only by the holder; and (C) amounts payable or shares issuable pursuant to
  an option shall be delivered only to (or for the account of) the holder.
         
       (ii) Certain Exceptions. The Committee by express provision in the
  Option Agreement may permit an option to be transferred to, exercised by
  and paid to certain persons or entities related to the participant,
  including but not limited to members of the participant's     
 
                                      A-2

 
     
  family, charitable institutions, or trusts or other entities whose
  beneficiaries or beneficial owners are members of the participant's family
  and/or charitable institutions, or to such other persons or entities as may
  be expressly approved by the Board or the Committee, pursuant to such
  conditions and procedures as the Board or the Committee may establish. Any
  permitted transfer shall be subject to the condition that the Committee
  receive evidence satisfactory to it that the transfer is being made for
  estate and/or tax planning purposes and on a basis consistent with the
  Company's registration of securities (if applicable) and the incentive
  purposes of the option and this Plan. Notwithstanding the foregoing,
  options intended as ISOs for purposes of the Code shall be subject to any
  and all additional transfer restrictions necessary to preserve their status
  as ISOs under the Code.     
     
       (iii) Further Exceptions to Limits on Transfer. The exercise and
  transfer restrictions in Section 5(f)(i) shall not apply to: (A) transfers
  to the Company; (B) the designation of a beneficiary to receive benefits in
  the event of the participant's death or, if the participant has died,
  transfers to or exercise by the participant's beneficiary, or, in the
  absence of a validly designated beneficiary, transfers by will or the laws
  of descent and distribution; (C) transfers pursuant to a domestic relations
  order (if approved or ratified by the Board or the     
  Committee); (D) if the participant has suffered a disability, permitted
  transfers to or exercises on behalf of the holder by his or her legal
  representative; or (E) the authorization by the Board or the Committee of
  "cashless exercise" procedures with third parties who finance or who
  otherwise facilitate the exercise of options consistent with applicable
  laws and the express authorization of the Committee.
   
   (g) Tax Withholding. Upon any exercise, vesting, or payment of any option,
the Company shall have the right, at its option, to (i) require the Eligible
Person (or personal representative or beneficiary, as the case may be) to pay
or provide for payment of the amount of any taxes which the Company may be
required to withhold with respect to such transaction or (ii) deduct from any
amount payable in cash the amount of any taxes which the Company may be
required to withhold with respect to such cash amount. In any case where a tax
is required to be withheld in connection with the delivery of Common Shares
under this Plan, the Committee may grant (either at the time of the grant of
the option or thereafter) to the participant the right to elect, pursuant to
such rules and subject to such conditions as the Committee may establish, to
have the Company reduce the number of shares to be delivered by (or otherwise
reacquire) the appropriate number of shares valued at their then fair market
value, to satisfy such withholding obligation.     
 
   6. ADJUSTMENTS.
 
   (a) Adjustments. If (i) the outstanding securities of the class then subject
to this Plan (the "OUTSTANDING SHARES") (A) are increased, decreased, exchanged
or converted as a result of a stock split (including a split in the form of a
stock dividend), reverse stock split, reclassification or the like or (B) are
exchanged for or converted into cash, property or a different number or kind of
securities (or if cash, property or securities are distributed in respect of
the outstanding shares), as a result of a reorganization, merger,
consolidation, recapitalization, restructuring, or reclassification, or (ii)
all or substantially all of the business and/or assets of the Company are sold,
THEN, unless the terms of such transaction shall otherwise provide, the
Committee shall make equitable, appropriate and proportionate adjustments in
(x) the number and type of shares or other securities or cash or
 
                                      A-3

 
   
other property that may be acquired pursuant to ISOs and other options
previously granted under this Plan, (y) the maximum number and type of shares
or other securities that may be issued pursuant to ISOs and other options
thereafter granted under this Plan, and (z) such other terms as necessarily are
affected by such event.     
 
   (b) Termination. If any option or other right to acquire Common Stock under
this Plan is fully vested but is not exercised prior to (i) a dissolution of
the Company, or (ii) any other Event after which the Company does not survive,
such Option or right shall thereupon terminate, provided that (y) the Company
or a successor shall have given to the participant at least ten (10) days
notice of any such termination, and participant shall have had the right prior
to or simultaneously with the consummation of such occurrence or transaction to

   10. LEGAL ISSUES.
 
   (a) Compliance And Choice Of Law; Severability. This Plan, the granting and
vesting of options under this Plan and the issuance and delivery of Common
Shares under options granted hereunder are subject to compliance with all
applicable federal and state laws, rules and regulations
 
                                      A-4

 
(including but not limited to state and federal securities law and federal
margin requirements) and to such approvals by any listing, regulatory or
governmental authority as may, in the opinion of counsel for the Company, be
necessary or advisable in connection therewith. Any securities delivered under
this Plan shall be subject to such restrictions as the Company may deem
necessary or desirable to assure compliance with all applicable legal
requirements. This Plan, the options, all documents evidencing options and all
other related documents shall be governed by, and construed in accordance with
the laws of the state of incorporation of the Company. If any provision shall
be held by a court of competent jurisdiction to be invalid and unenforceable,
the remaining provisions of this Plan (subject to Section 10(b)) shall continue
in effect.
 
   (b) Plan Construction. It is the intent of the Company that transactions in
and affecting options in the case of participants who are or may be subject to
Section 16 of the Securities Exchange Act of 1934, as amended, satisfy any then
applicable requirements of Rule 16b-3 so that such persons (unless they
otherwise agree) will be entitled to the benefits of Rule 16b-3 or other
exemptive rules under Section 16 in respect of those transactions and will not
be subjected to avoidable liability thereunder. If any provision of this Plan
or of any option would otherwise frustrate or conflict with the intent
expressed above, that provision to the extent possible shall be interpreted as
to avoid such conflict. If the conflict remains irrevocable, the Committee may
disregard the provision if it concludes that to do so furthers the interest of
the Company and is consistent with the purposes of this Plan as to such persons
in the circumstances.
 
   (c) Non-Exclusivity Of Plan. Nothing in this Plan shall limit or be deemed
to limit the authority of the Board or the Committee to grant options or
authorize any other compensation, with or without reference to the Common
Shares, under any other plan or authority.

                                      B-1

 
ARTICLE 2. THE OPTIONS
 
   2.1 Option Terms.
 
     (a) Automatic Option Grants. Subject to adjustments contemplated by
  Section 3.3, each holder of a Primadonna Director Option shall be granted
  an Option to purchase that number of shares of Common Stock which is the
  product of (y) the number of shares of Primadonna's common stock subject to
  the holder's Primadonna Option and (z) .33, the conversion ratio pursuant
  to the Merger Agreement.
 
     (b) Option Price. The purchase price per share of the Common Stock
  covered by each Option granted pursuant to Section 2.1(a) shall be
  determined by dividing the option price of the Primadonna Director Option
  it replaces by .33 and rounding up to the nearest whole cent.
 
     (c) Option Period and Exercisability. Each Option granted under this
  Plan shall become exercisable in installments at the rate of one-third of
  the shares underlying such Option on the Option Date on the first
  anniversary of the Option Date and an additional one-third of such shares
  on each of the next two anniversaries thereof.
 
     (d) Non-Qualified Options. Each Option granted under this Plan is
  intended to be a non-qualified stock option (i.e., not an "incentive stock
  option") under the Internal Revenue Code and shall be so designated.
 
   2.2 Payment of Exercise Price. The exercise price of any Option granted
under this Plan shall be paid in full at the time of each exercise in cash or
by check or in shares of Common Stock valued at their Fair Market Value on the
date of exercise of the Option, or partly in such shares and partly in cash,
provided that any such shares used in payment shall have been owned by the
Participant at least six months prior to the date of the exercise.
 
   2.3 Option Period. Each Option granted under this Plan and all rights or
obligations thereunder shall expire ten (10) years after the Option Date and
shall be subject to earlier termination as provided herein.
   
   2.4 Effect of Termination of Service. If a Participant dies while serving as
a director or within the three-month period following termination of service as
a director and the Participant had been an Eligible Director for at least three
(3) years, any Option granted pursuant to this Plan then held by such
Participant shall immediately become and shall remain fully exercisable for
twelve (12) months after the date of death or until the expiration of the
stated term of such Option, whichever first occurs, and shall thereafter
terminate. If a Participant dies while serving as a director or within the
three-month period following termination of service as a director and the
Participant had been an Eligible Director for less than three (3) years, any
portion of any Option granted pursuant to this Plan which is not then
exercisable shall terminate and any portion of such Option which is then
exercisable may be exercised for twelve (12) months after the date of death or
until the expiration of the stated term, whichever first occurs, and shall
thereafter terminate. If a Participant's services as a member of the Board
terminate for any other reason, then (except to the extent otherwise provided
in this Section 2.4) any portion of an Option granted pursuant to this Plan
which is not then exercisable shall terminate and any portion of such Option
which is then exercisable may be exercised for three (3) months after the date
of such termination or until the expiration of the stated term, whichever first
occurs, and shall thereafter terminate.     
 
                                      B-2

 
   2.5 Limitations on Exercise and Vesting of Options.
 
     (a) Provisions for Exercise. No Option shall be exercisable or shall
  vest until at least six months after the initial Option Date, and once
  exercisable an Option shall remain exercisable until the expiration or
  earlier termination of the Option.
 
     (b) Procedure. Any exercisable Option shall be deemed to be exercised
  when the Secretary of the Corporation receives written notice of such
  exercise from the Participant, together with the required payment of the
  exercise price.
 
     (c) Fractional Shares/Minimum Issues. Fractional share interests shall
  be disregarded, but may be accumulated. No fewer than 100 shares may be
  purchased on exercise of any Option at one time unless the number purchased
  is the total number at the time available for purchase under the Option.
   
ARTICLE 3. OTHER PROVISIONS     
 
   3.1 Rights of Participants and Beneficiaries.
 
     (a) No Service Commitment. Nothing contained in this Plan (or in any
  other documents related to this Plan or to any Option) shall confer upon
  any Participant any right to continue to serve as a director of the
  Corporation nor shall interfere in any way with the right of the
  Corporation to change director compensation or other benefits or to
  terminate the director's service as a director, with or without cause.
  Nothing contained in this Plan or any document related hereto shall
  influence the construction or interpretation of the Corporation's
  Certificate of Incorporation or Bylaws regarding service on the Board or
  adversely affect any independent contractual right of any Eligible Director
  without his or her consent thereto.

  reserve, fund or deposit shall be made to assure payment of such Options.
 
   3.2 No Transferability. Options may be exercised only by, and shares
issuable pursuant to an Option shall be paid only to, the Participant or, if
the Participant has died, the Participant's Beneficiary or, if the Participant
has suffered a disability, the Participant's Personal Representative, if any,
or if there is none, the Participant, or (to the extend permitted by applicable
law and Rule 16b-3) to a third party pursuant to such conditions and procedures
as the Board may establish. Other than by will or the laws of descent and
distribution or pursuant to an exception (by rule or interpretation) to
transfer restrictions under Rule 16b-3, no right or benefit under this Plan or
any Option, including, without limitation, any Option that has not vested,
shall be transferrable by the Participant or shall be subject in any manner to
anticipation, alienation, sale, transfer, assignment, pledge, encumbrance or
charge and any such attempted action shall be void. The designation of a
Beneficiary hereunder shall not constitute a transfer for these purposes.
 
   3.3 Adjustments. If there shall occur any extraordinary distribution in
respect of the Common Stock (whether in the form of Common Stock, other
securities, or other property), or any recapitalization, stock split (including
a stock split in the form of a stock dividend), reverse stock split,
reclassification, reorganization, merger, combination, consolidation, split-up,
spin-off,
 
                                      B-3

 
   
combination, or exchange or Common Stock or other securities of the
Corporation, or a sale of substantially all of the assets of the Corporation as
an entirety, then the Board shall, in such manner and to such extent (if any)
as may be appropriate and equitable, (1) proportionately adjust any or all of
(a) the number and type of shares of Common Stock (or other securities) which
thereafter may be made the subject of Options (including the specific maxima
and numbers of shares set forth elsewhere in this Plan), (b) the number, amount
and type of shares of Common Stock (or other securities or property) subject to
any or all outstanding Options and the vesting provisions of the Options, (c)
the grant, purchase, or exercise price of any or all outstanding Options, or
(d) the securities, cash or other property deliverable upon exercise of any
outstanding Options, or (2) in the case of any extraordinary distribution,
merger, reorganization, consolidation, combination, sale of assets, split up,
exchange, or spin off, make provision for a substitution or exchange of any or
all outstanding Options or for a change in the securities, cash or property
deliverable upon exercise of outstanding Options, based upon the distribution
or consideration payable to holders of the Common Stock of the Corporation upon
or in respect of such event; provided, however, that (i) such adjustment and
the Board's actions in respect thereof are based on objective criteria and (ii)
such adjustment (to the extent consistent with Section 3.9(c)) is consistent
with adjustments to comparable Options (if any) held by persons other than
directors of the Corporation.     
 
   3.4 Compliance with Laws. This Plan, the granting and vesting of Options
under this Plan and the issuance and delivery of shares of Common Stock, and/or
of other securities or property pursuant to Section 3.3, under this Plan or
under Options granted hereunder are subject to compliance with all applicable
federal and state laws, rules and regulations (including but not limited to
state and federal tax and securities laws) and to such approvals by and
listing, regulatory or governmental authority as may, in the opinion of counsel
for the Corporation, be necessary or advisable in connection therewith. Any
securities delivered under this Plan shall be subject to such restrictions, and
the person acquiring such securities shall, if requested by the Corporation,
provide such assurances and representations to the Corporation as the
Corporation may deem necessary or desirable to assure such compliance.
 
   3.5 Plan Amendment, Shareholder Approval and Suspension.
 
     (a) Board Authorization The Board may, at any time, terminate or, from
  time to time, amend, modify or suspend this Plan, in whole or in part. No
  Options may be granted during any suspension of this Plan or after
  termination of this Plan, but the Board shall retain jurisdiction as to
  Options then outstanding in accordance with the terms of this Plan.
 
     (b) Stockholder Approval. To the extent required by law or the
  provisions of Rule 16b-3, any amendment to this Plan or any then
  outstanding Option shall be subject to shareholder approval.
 
     (c) Limitations on Amendments to Plan and Options. The provisions of
  this Plan shall not be amended more than once every six months (other than
  as may be necessary to conform to any applicable changes in the Internal
  Revenue Code or the rules thereunder), unless such amendment would be
  consistent with the provisions of Rule 16b-3(c)(2)(ii) (or any successor
  provision). No amendment, suspension or termination of this Plan or change
  of or affecting any outstanding Option shall, without written consent of
  the Participant, affect in any manner materially adverse to the Participant
  any rights or benefits of the Participant or obligations of the
 
                                      B-4

 
  Corporation under any Option granted under this Plan prior to the effective
  date of such change. Changes contemplated by Section 3.3 shall not be
  deemed to constitute changes or amendments for purposes of this Section
  3.5.
 
   3.6 Privileges of Stock Ownership. Except as otherwise expressly authorized

Merger is consummated.
 
   3.8 Term of Plan. No Option shall be granted more than ten (10) years after

Plan or in an applicable Option Agreement, any Option theretofore granted may
extend beyond such date, and this Plan shall continue to apply thereto.
 
   3.9 Legal Issues.
 
     (a) Choice of Law. This Plan, the Options, all documents evidencing
  Options and all other related documents shall be governed by, and construed
  in accordance with the laws of the state of incorporation of the
  Corporation.
 
     (b) Severability. If any provision shall be held by a court of competent
  jurisdiction to be invalid and unenforceable, the remaining provisions of
  this Plan shall continue in effect.
     
     (c) Plan Construction. It is the intent of the Corporation that this
  Plan and Options hereunder satisfy and be interpreted in a manner that in
  the case of persons who are or may be subject to Section 16 of the Exchange
  Act satisfies the applicable requirements of Rule 16b-3 so that such
  persons will be entitled to the benefits of Rule 16b-3 or other exemptive
  rules under Section 16 of the Exchange Act and will not be subjected to
  avoidable liability thereunder. If any provision of this Plan or if any
  Option would otherwise frustrate or conflict with the intent expressed
  above, that provision to the extent possible shall be interpreted and
  deemed amended so as to avoid such conflict, but to the extent as to such
  persons in the circumstances, such provision shall be deemed void.     
 
     (d) Non-Exclusivity of Plan. Nothing in this Plan shall limit or be
  deemed to limit the authority of the Board to grant awards or authorize any
  other compensation under any other plan or authority.
