Agreement) and to otherwise supervise the administration of the Plan. The
Committee's policies and procedures may differ with respect to different
Options.

     Any determination made by the Committee pursuant to the provisions of the
Plan shall be made in its sole discretion, and in the case of any determination
relating to an Option, may be made at the time of the grant of the Option or,

                             STOCK SUBJECT TO PLAN
                             ---------------------

          ----------------                                                   
total number of shares of Common Stock reserved and available for distribution
pursuant to Options under the Plan shall be six hundred thousand (600,000)
shares of Common Stock authorized for issuance on the Effective Date.  Such
shares may consist, in whole or in part, of authorized and unissued shares or
treasury shares.

     4.2  Release of Shares.   If any shares of Common Stock that have been
          -----------------                                                
optioned cease to be subject to an Option, if any shares of Common Stock that
are subject to any Option are forfeited, if any Option otherwise terminates
without issuance of shares of Common Stock being made to the Participant, or if
any shares (whether or not restricted) of Common Stock are received by the
Company in connection with the exercise of an Option, such shares, in the
discretion of the Committee, may again be available for distribution in
connection with Options under the Plan.

     4.3  Restrictions on Shares.  Shares of Common Stock issued upon exercise
          ----------------------                                              
of an Option shall be subject to the terms and conditions specified herein and
to such other terms, conditions and restrictions as the Committee in its
discretion may determine or provide in the Option Agreement.  The Company shall
not be required to issue or deliver any certificates for shares of Common Stock,
cash or other property prior to (i) the listing of such shares on any stock
exchange (or other public market) on which the Common Stock may then be listed
(or regularly traded), (ii) the completion of any registration or qualification
of such shares under federal or state law, or any ruling or regulation of any
government body which the Committee determines to be necessary or advisable, and
(iii) the satisfaction of any applicable withholding obligation in order for the
Company or an Affiliate to obtain a deduction with respect to the exercise of an
Option. The Company may cause any certificate for any share of Common Stock to
be delivered to be properly marked with a legend or other notation reflecting
the limitations on transfer of such Common Stock as provided in the Plan or as
the Committee may otherwise require.  The Committee may require any person
exercising an Option to make such representations and furnish such information
as it may consider appropriate in connection with the issuance or delivery of
the 

                                      -8-

 
shares of Common Stock in compliance with applicable law or otherwise.
Fractional shares shall not be delivered, but shall be rounded to the next lower
whole number of shares.

     4.4  Stockholder Rights.  No person shall have any rights of a stockholder
          ------------------                                                   
as to shares of Common Stock subject to an Option until, after proper exercise
of the Option or other action required, such shares shall have been recorded on
the Company's official stockholder records as having been issued or transferred.
Upon exercise of the Option or any portion thereof, the Company will have thirty
(30) days in which to issue the shares, and the Participant will not be treated
as a stockholder for any purpose whatsoever prior to such issuance.  No
adjustment shall be made for cash dividends or other rights for which the record
date is prior to the date such shares are recorded as issued or transferred in
the Company's official stockholder records, except as provided herein or in an
Agreement.

     4.5  Best Efforts To Register.  The Company will register under the
          ------------------------                                      
Securities Act the Common Stock delivered or deliverable pursuant to Options on
Commission Form S-8 if available to the Company for this purpose (or any
successor or alternate form that is substantially similar to that form to the
extent available to effect such registration), in accordance with the rules and
regulations governing such forms, as soon as such forms are available for
registration to the Company for this purpose.  The Company will use its best
efforts to cause the registration statement to become effective as soon as
possible and will file such supplements and amendments to the registration
statement as may be necessary to keep the registration statement in effect until
the earliest of (a) one year following the expiration of the Option Period of
the last Option outstanding, (b) the date the Company is no longer a reporting
company under the Exchange Act and (c) the date all Participants have disposed
of all shares delivered pursuant to any Option.  The Company may delay the
foregoing obligation if the Committee reasonably determines that any such
registration would materially and adversely affect the Company's interests or if
there is no material benefit to Participants.

     4.6  Anti-Dilution.  In the event of any Company stock dividend, stock
          -------------                                                    
split, combination or exchange of shares, recapitalization or other change in
the capital structure of the Company, corporate separation or division of the
Company (including, but not limited to, a split- up, spin-off, split-off or
distribution to Company stockholders other than a normal cash dividend), sale by
the Company of all or a substantial portion of its assets (measured on either a
stand-alone or consolidated basis), reorganization, rights offering, a partial
or complete liquidation, or any other corporate transaction, Company share
offering or event involving the Company and having an effect similar to any of
the foregoing, then the Committee shall adjust or substitute, as the case may
be, the number of shares of Common Stock available for Options under the Plan,
the number of shares of Common Stock covered by outstanding Options, the
exercise price per share of outstanding Options, and any other characteristics
or terms of the Options as the Committee shall deem necessary or appropriate to
reflect equitably the effects of such changes to the Participants; provided,
however, that any fractional shares resulting from such adjustment shall be
eliminated by rounding to the next lower whole number of shares with appropriate
payment for such fractional share as shall reasonably be determined by the
Committee.

          ------------------                                                   
Date shall be granted an Option on the Effective Date to purchase ten thousand
(10,000) shares of Common Stock without further action by the Board or the
Committee.  On each Grant Date after the Effective Date each person who is a
Director on such Grant Date shall be granted an Option to purchase one thousand
(1,000) shares of Common Stock without further action by the  Board or the
Committee.  If the number of shares of Common Stock available to grant under the
Plan on a scheduled date of grant is insufficient to make all automatic grants
required to be made pursuant to the Plan on such date, then each eligible
Director shall receive an Option to purchase a pro rata number of the remaining
shares of Common Stock available under the Plan; provided further, however, that
if such proration results in fractional shares of Common Stock, then such Option
shall be rounded down to the nearest number of whole shares of Common Stock.
Each Option granted under the Plan shall be evidenced by an Agreement, in a form
approved by the Committee, which shall embody the terms and conditions of such
Option and which shall be subject to the express terms and conditions set forth
in the Plan.

     5.3  Terms and Conditions.  Options shall be subject to such terms and
          --------------------

              ------------                                                    
     Market Value per share on the Grant Date.

          (b) Option Period.  The Option Period of each Option shall be ten (10)
              -------------

              --------------                                                    
     shall be exercisable upon the earliest of the date of the Participant's
     death or Disability and the date that is the six-month anniversary of the
     Grant Date.  If the Committee provides that any Option is exercisable only
     in installments, the Committee may at any time waive such installment
     exercise provisions, in whole or in part.  In addition, the Committee may
     at any time accelerate the exercisability of any Option.  Any Option not
     yet exercised shall be forfeited if the Participant incurs a Termination of
     Directorship due to Cause.

          (d) Method of Exercise.  A Participant desiring to exercise an Option,
              ------------------                                                
     in whole or in part, at any time during the Option Period must give written
     notice of exercise on a form provided by the Committee (if available) to
     the Company specifying the number of shares of Common Stock subject to the
     Option to be purchased.  Such notice shall be accompanied by payment in
     full of the purchase price by cash or check or such other form 

                                      -10-

 
     of payment as the Company may accept. If approved by the Committee, payment
     in full or in part may also be made (i) by delivering Common Stock already
     owned by the Participant having a total Fair Market Value on the date of
     such delivery equal to the Option Price; (ii) by the execution and delivery
     of a note or other evidence of indebtedness (and any security agreement
     thereunder) satisfactory to the Committee and permitted in accordance with
     Section 5.3(e); (iii) by authorizing the Company to retain shares of Common
     Stock which would otherwise be issuable upon exercise of the Option having
     a total Fair Market Value on the date of delivery equal to the Option
     Price; (iv) by the delivery of cash or the extension of credit by a broker-
     dealer to whom the Participant has submitted a notice of exercise or
     otherwise indicated an intent to exercise (in accordance with Part 220,
     Chapter II, Title 12 of the Code of Federal Regulations, so-called
     "cashless" exercise); or (v) by any combination of the foregoing. No shares
     of Common Stock shall be issued until full payment therefor has been made.

          (e) Company Loan or Guarantee.  Upon the exercise of any Option and
              -------------------------                                      
     subject to the pertinent Agreement and the discretion of the Committee, the
     Company may at the request of the Participant:

                    (i)  lend to the Participant, with recourse, an amount equal
          to such portion of the Option Price as the Committee may determine; or

                    (ii) guarantee a loan obtained by the Participant from a
          third-party for the purpose of tendering the Option Price.

          The terms and conditions of any loan or guarantee, including the term,
     interest rate, and any security interest thereunder, shall be determined by
     the Committee, except that no extension of credit or guarantee shall
     obligate the Company for an amount to exceed the lesser of the aggregate
     Fair Market Value per share of the Common Stock on the date of exercise,
     less the par value of the shares of Common Stock to be purchased upon the
     exercise of the Option, or the amount permitted under applicable laws or
     the regulations and rules of the Federal Reserve Board and any other
     governmental agency having jurisdiction.

          (f) Non-transferability of Options.  Except as provided herein or in
              ------------------------------                                  
     an Agreement, no Option shall be transferable by the Participant other than
     by will or by the laws of descent and distribution, and all Options shall
     be exercisable during the Participant's lifetime only by the Participant.
     If and to the extent transferability is permitted by Rule 16b-3 and except
     as otherwise provided herein or in an Agreement, every Option granted
     hereunder shall be freely transferable but only if such transfer is exempt
     under Rule 16b-3 or is made pursuant to a domestic relations order which
     would be a "qualified domestic relations order" as defined in Section 414
     of the Code if such section applied to the Option.

                                      -11-

 
          (g) Cashing Out of Option; Settlement of Spread Value in Stock.  On
              ----------------------------------------------------------     
     receipt of written notice of exercise of any Option for which at least six
     months has elapsed since the Grant Date (provided that such limitation of
     six months shall not apply to an Option granted to a Participant who has
     subsequently died), the Committee may elect to cash out all or part of the
     portion of any Option to be exercised by paying the Participant an amount,
     in cash or Common Stock, equal to the Spread times the number of shares of
     Common Stock subject to the Option on the effective date of such cash out.
     Cash outs relating to Options held by a Participant who is actually or
     potentially subject to Section 16(b) of the Exchange Act shall comply with
     the "window period" provisions of Rule 16b-3, to the extent applicable, and
     the Committee may determine the Spread by applying the Fair Market Value
     based on the highest mean sales price of the Common Stock on any exchange
     on which the Common Stock is listed (or NASDAQ) on any day during such
     "window period."

shares of Common Stock received pursuant to the exercise of an Option to his
parents, spouse or descendants or to any trust for the benefit of the foregoing
or to a custodian under a uniform gifts to minors act or similar statute for the
benefit of any of the Participant's descendants.  Any transfer of shares
received pursuant to the exercise of an Option shall not be permitted or valid
unless and until the transferee agrees to be bound by the provisions of the
Plan, and any provision respecting Common Stock under the Agreement, provided
that "Termination of Employment" shall continue to refer to the Termination of
Employment of the Participant.

     6.2  Limited Transfer During Offering.  In the event there is an effective
          --------------------------------                                     
registration statement under the Securities Act pursuant to which shares of
Common Stock shall be offered for sale in an underwritten offering, a
Participant shall not, during the  period requested by the underwriters managing
the registered public offering, effect any public sale or distribution of shares
received directly or indirectly pursuant to an exercise of an Option.

     6.3  Committee Discretion.  The Committee may in its sole discretion
          --------------------                                           
include in any Agreement an obligation that the Company purchase a Participant's
shares of Common Stock received upon the exercise of an Option (including the
purchase of any unexercised Options which have not expired), or may obligate a
Participant to sell shares of Common Stock to the Company upon such terms and
conditions as the Committee may determine and set forth in an Agreement.  The
provisions of this Article X shall be construed by the Committee in its sole
discretion, and shall be subject to such other terms and conditions as the
Committee may from time to time determine.  Notwithstanding any provision herein
to the contrary, the Company may upon determination by the Committee assign its
right to purchase shares of Common Stock under 

                                      -12-

 
this Article X, whereupon the assignee of such right shall have all the rights,
duties and obligations of the Company with respect to purchase of the shares of
Common Stock.

     6.4  No Company Obligation.  None of the Company, an Affiliate or the
          ---------------------                                           
Committee shall have any duty or obligation to affirmatively disclose to a
record or beneficial holder of Common Stock or an Option, and such holder shall
have no right to be advised of any material information regarding the Company or
any Affiliate at any time prior to, upon or in connection with receipt or the
exercise of an Option or the Company's purchase of Common Stock or an Option
from such holder in accordance with the terms hereof.

     6.5  Sale of Grossman/Issette Interest.  Unless otherwise provided in an
          ---------------------------------                                  
Agreement, the Company shall give notice to each Participant with respect to a
sale or series of sales of any Grossman/Issette Interest other than a sale to a
Grossman/Issette Entity.  Upon receipt of such notice, each Participant shall,
if such notice so directs, sell to such proposed purchaser a percentage of the
Participant's shares of Common Stock owned and acquired pursuant to the Plan
(including any shares of Common Stock which could yet be acquired pursuant to an
Option) equal to that percentage of all shares of Common Stock owned by the
Grossman/Issette Entities which are to be sold by the Grossman/Issette Entities
to such purchaser on the same terms and conditions, including at the price per
share of Common Stock to be paid, as in the sale by the Grossman/Issette
Entities.


                                   ARTICLE VII
                                   -----------

                          CHANGE IN CONTROL PROVISIONS
                          ----------------------------

     7.1  Impact of Event.  Notwithstanding any other provision of the Plan to
          ---------------                                                     
the contrary, in the event of a Change in Control:

          (a) Any Options outstanding as of the date such Change in Control and
     not then exercisable shall become fully exercisable to the full extent of
     the original grant;

          (b) Notwithstanding any other provision of the Plan, unless the
     Committee shall provide otherwise in an Agreement, a Participant shall have
     the right, whether or not the Option is fully exercisable or may be
     otherwise realized by the Participant, by giving notice during the 60-day
     period from and after a Change in Control to the Company, to elect to
     surrender all or part of the Option to the Company and to receive cash,
     within 30 days of such notice, in an amount equal to the Spread, based on
     the Change in Control Price, times the number of shares of Common Stock
     subject to Option on the date of such election as to which the right
     granted hereunder shall have been exercised; provided, however, that if the
     end of such 60-day period from and after a Change in Control is within six
     months of the date of grant of the Option held by a Participant (except a
     Participant who has died during such six month period), such Option shall
     be cancelled in exchange for a payment to the Participant on the date of
     the Participant's Termination of 

                                      -13-

 
         Directorship, equal to the Spread multiplied by the number of shares of
         Common Stock granted under the Option, and increased from the date of
         the change in control to the date of the Termination of Directorship by
         the prime rate as reported from time to time in The Wall Street Journal
         or other general publication. The 60-day period shall be extended, if
         necessary, to include the "window period" of Rule 16(b)-3 which first
         commences on or after the date of the Change in Control, and the
         Committee shall have sole discretion, if necessary, to approve the
         Participant's exercise hereunder and the date in which the Spread is
         calculated may be adjusted, if necessary, to a later date if necessary
         to avoid liability to such Participant under Section 16(b).



                                 ARTICLE VIII
                                 ------------

                                 MISCELLANEOUS
                                 -------------
                                        
       8.1     Amendments and Termination.  The Board may amend, alter,
               --------------------------
discontinue or terminate the Plan at any time, but no amendment, alteration,
discontinuation or termination shall be made which would (a) reduce the current
value of an Account or impair the rights of a Participant under an Option
theretofore granted without the Participant's consent, except such an amendment
made to cause the Plan to qualify for the exemption provided by Rule 16b-3 or
(b) disqualify the Plan from the exemption provided by Rule 16b-3. In addition,
no such amendment shall be made without the approval of the Company's
stockholders to the extent such approval is required by law or agreement.
Notwithstanding the foregoing, the Plan may not be amended more than once every
six (6) months to change the Plan provisions listed in section (c)(2)(ii)(A) of
Rule 16b-3, other than to comport with changes in the Code or Rule 16b-3.

         The Committee may amend the Plan at any time provided that (a) no
amendment shall impair the rights of any Participant under any Option
theretofore granted without the Participant's consent, (b) no amendment shall
disqualify the Plan from the exemption provided by Rule 16b-3, and (c) any
amendment shall be subject to the approval or rejection of the Board.

         The Committee may amend the terms of any Option, prospectively or
retroactively, but no such amendment shall impair the rights of any Participant
without the Participant's consent, except such an amendment made to cause the
Plan or Option to qualify for the exemption provided by Rule 16b-3. The
Committee may also substitute new Options for previously granted Options,
including previously granted Options having higher Option Prices but no such
substitution shall be made which would impair the rights of Participants under
such Option theretofore granted without the Participant's consent. The
Committee's discretion to amend the Plan or Agreement shall be limited to the
Plan's constituting a plan described in Rule 16b-3.

                                      -14-

 
         Subject to the above provisions, the Board shall have authority to
amend the Plan to take into account changes in law and tax and accounting rules,
as well as other developments and to grant Options which qualify for beneficial
treatment under such rules without stockholder approval.

         The Board may terminate the Plan at any time.

       8.2     Unfunded Status of Plan.  It is intended that the Plan be an
               -----------------------                                     
"unfunded" plan for incentive and deferred compensation. The Committee may
authorize the creation of trusts or other arrangements to meet the obligations
created under the Plan to deliver Common Stock or make payments; provided,
however, that, unless the Committee otherwise determines, the existence of such
trusts or other arrangements is consistent with the "unfunded" status of the
Plan.

       8.3     General Provisions.
               ------------------ 

               (a)    Representation.  The Committee may require each person
         purchasing or receiving shares pursuant to an Option to represent to
         and agree with the Company in writing that such person is acquiring the
         shares without a view to the distribution thereof. The certificates for
         such shares may include any legend which the Committee deems
         appropriate to reflect any restrictions on transfer.

               (b)    No Additional Obligation.  Nothing contained in the Plan
                      ------------------------
         shall prevent the Company or an Affiliate from adopting other or
         additional compensation arrangements for Directors or employees.

               (c)    Withholding.  No later than the date as of which an amount
                      -----------
         first becomes includible in the gross income of the Participant for
         Federal income tax purposes with respect to any Option, the Participant
         shall pay to the Company (or other entity identified by the Committee),
         or make arrangements satisfactory to the Company or other entity
         identified by the Committee regarding the payment of, any Federal,
         state, local or foreign taxes of any kind required by law to be
         withheld with respect to such amount required in order for the Company
         or an Affiliate to obtain a current deduction. Unless otherwise
         determined by the Committee, withholding obligations may be settled
         with Common Stock, including Common Stock that is part of the Option
         that gives rise to the withholding requirement provided that any
         applicable requirements under Section 16 of the Exchange Act are
         satisfied. The obligations of the Company under the Plan shall be
         conditional on such payment or arrangements, and the Company and its
         Affiliates shall, to the extent permitted by law, have the right to
         deduct any such taxes from any payment otherwise due to the
         Participant.

               (d)    Representation.  The Committee shall establish such
                      --------------
         procedures as it deems appropriate for a Participant to designate a
         Representative to whom any amounts payable in the event of the
         Participant's death are to be paid.

                                      -15-

 
               (e)    Controlling Law.  The Plan and all Options made and
                      ---------------
         actions taken thereunder shall be governed by and construed in
         accordance with the laws of the State of Delaware (other than its law
         respecting choice of law). The Plan shall be construed to comply with
         all applicable law, and to avoid liability to the Company, an Affiliate
         or a Participant, including, without limitation, liability under
         Section 16(b) of the Exchange Act.

               (f)    Offset.  Any amounts owed to the Company or an Affiliate
                      ------
         by the Participant of whatever nature may be offset by the Company from
         the value of any shares of Common Stock, cash or other thing of value
         under the Plan or an Agreement to be transferred to the Participant,
         and no shares of Common Stock, cash or other thing of value under the
         Plan or an Agreement shall be transferred unless and until all disputes
         between the Company and the Participant have been fully and finally
         resolved and the Participant has waived all claims to such against the
         Company or an Affiliate.

       8.4     Certain Rights.  Nothing contained herein shall be deemed to
               --------------
alter the relationship between the Company or an Affiliate and a Participant, or
the contractual relationship between a Participant and the Company or an
Affiliate if there is a written contract regarding such relationship. Nothing
contained herein shall be construed to constitute a contract of employment or
appointment between the Company or an Affiliate and a Participant. The Company
or an Affiliate and each of the Participants continue to have the right to
terminate the employment or other relationship at any time for any reason,
except as provided in a written contract. The Company or an Affiliate shall have
no obligation to retain the Participant in its employ or service as a result of
the Plan. There shall be no inference as to the length of employment or service
hereby, and the Company or an Affiliate reserves the same rights to terminate
the Participant's employment or service as existed prior to the individual
becoming a Participant in the Plan.

       8.5     Options in Substitution for Options Granted by Other
               ----------------------------------------------------  
Corporations.  Options may be granted under the Plan from time to time in
- ------------
substitution for awards held by employees, directors or service providers of
other corporations who are about to become Directors of the Company or an
Affiliate as the result of a merger or consolidation of the employing
corporation with the Company or an Affiliate, or the acquisition by the Company
or an Affiliate of the assets of the employing corporation, or the acquisition
by the Company or Affiliate of the stock of the employing corporation, as the
result of which it becomes a designated employer under the Plan. The terms and
conditions of the Options so granted may vary from the terms and conditions set
forth in the Plan at the time of such grant as the majority of the members of
the Committee may deem appropriate to conform, in whole or in part, to the
provisions of the awards in substitution for which they are granted.

       8.6     Procedure for Adoption.  Any Affiliate of the Company may by
               ----------------------                                      
resolution of such Affiliate's board of directors, with the consent of the Board
of Directors and subject to such conditions as may be imposed by the Board of
Directors, adopt the Plan for the benefit of its Directors as of the date
specified in the board resolution.

                                      -16-

 
       8.7     Procedure for Withdrawal.  Any Affiliate which has adopted the
               ------------------------ 
Plan may, by resolution of the board of directors of such direct or indirect
subsidiary, with the consent of the Board of Directors and subject to such
conditions as may be imposed by the Board of Directors, terminate its adoption
of the Plan.

       8.8     Delay.  If at the time a Participant incurs a Termination of
               -----                                                       
Directorship (other than due to Cause) or if at the time of a Change in Control,
the Participant is subject to "short-swing" liability under Section 16 of the
Exchange Act, any time period provided for under the Plan or an Agreement to the
extent necessary to avoid the imposition of liability shall be suspended and
delayed during the period the Participant would be subject to such liability,
but not more than six (6) months and one (1) day and not to exceed the Option
Period. The Company shall have the right to suspend or delay any time period
described in the Plan or an Agreement if the Committee shall determine that the
action may constitute a violation of any law or result in liability under any
law to the Company, an Affiliate or a stockholder of the Company until such time
as the action required or permitted shall not constitute a violation of law or
result in liability to the Company, an Affiliate or a stockholder of the
Company. The Committee shall have the discretion to suspend the application of
the provisions of the Plan required solely to comply with Rule 16b-3 if the
Committee shall determine that Rule 16b-3 does not apply to the Plan.

       8.9     Headings.  The headings contained in the Plan are for reference
               --------                                                       
purposes only and shall not affect the meaning or interpretation of the Plan.

       8.10    Severability.  If any provision of the Plan shall for any reason
               ------------
be held to be invalid or unenforceable, such invalidity or unenforceability
shall not effect any other provision hereby, and the Plan shall be construed as
if such invalid or unenforceable provision were omitted.

       8.11    Successors and Assigns. The Plan shall inure to the benefit of
               ---------------------- 
and be binding upon each successor and assign of the Company. All obligations
imposed upon a Participant, and all rights granted to the Company hereunder,
shall be binding upon the Participant's heirs, legal representatives and
successors.

       8.12    Entire Agreement.  The Plan and the Agreement constitute the
               ----------------
entire agreement with respect to the subject matter hereof and thereof, provided
that in the event of any inconsistency between the Plan and the Agreement, the
terms and conditions of the Plan shall control.
