          shares  of  common  stock  subject  to the  restrictions  set forth in

     The  provisions of Articles One shall apply to both equity  programs  under
the Plan and shall  accordingly  govern the  interests of all persons  under the
Plan.

     The Board or Committee  shall have full  authority to  determine,  (i) with
respect  to the  grants  made under the Option  Grant  Program,  which  eligible
persons are to receive the option grants,  the time or times when each option is
to become  exercisable,  the vesting  schedule and events (if any) applicable to

outstanding,  and (ii) with respect to stock issuances made under the Restricted
Shares  Issuance  Program,  which  eligible  persons  are to receive  such stock
issuances,  the time or times when those issuances are to be made, the number of
shares to be issued to each Participant, and the vesting schedule and events (if

     The Board or Committee shall have the absolute  discretion  either to grant
options  in  accordance  with the  Option  Grant  Program  or to issue  stock in
accordance with the Restricted Shares Issuance Program.

1.4  Administration of the Plan
     --------------------------

     The Plan shall be administered  by the Board or by the Committee  appointed
by the Board consisting of two or more members of the Board all of whom shall be
Non-Employee  Directors.  The Committee shall serve at the pleasure of the Board

                                       3

and shall have such powers as the Board may, from time to time, confer upon it.

     Subject to this Section 1.4,  the  Committee or Board,  as the case may be,
shall have sole and  complete  authority to adopt,  alter,  amend or revoke such
administrative  rules,  guidelines and practices  governing the operation of the
Plan as it shall, from time to time, deem advisable,  and to interpret the terms
and provisions of the Plan.

     The  Committee  or Board,  as the case may be,  shall  keep  minutes of its
meetings  and of  action  taken by it  without  a  meeting.  A  majority  of the
Committee or Board shall constitute a quorum,  and the acts of a majority of the
members present at any meeting at which a quorum is present, or acts approved in
writing by all of the members of the Committee or Board without a meeting, shall
constitute the acts of the Committee.

1.5  Eligibility
     -----------

     Options and  Restricted  Shares may be granted only to new employees of the
Company or a Subsidiary or Affiliate whose options are issued in connection with
his or her employment as a new employee.

1.6  Shares
     ------

     The aggregate  number of shares reserved for issuance  pursuant to the Plan
shall be  600,000  shares of Common  Stock,  or the number and kind of shares of
stock or other securities which shall be substituted for such shares or to which
such shares shall be adjusted as provided in Section 1.6.

     Such number of shares may be set aside out of the  authorized  but unissued
shares of Common Stock or out of issued shares of Common Stock  acquired for and
held in the Treasury of the Company, not reserved for any other purpose.  Shares
subject to, but not sold or issued under, any Option terminating or expiring for
any reason  prior to its  exercise in full will again be  available  for Options
thereafter granted during the balance of the term of the Plan.

1.7  Adjustments Due to Stock Splits, Mergers, Consolidation, Etc.
     -------------------------------------------------------------

     If, at any time,  the  Company  shall  take any  action,  whether  by stock
dividend,  stock split,  combination of shares or otherwise,  which results in a
proportionate  increase  or  decrease  in the  number of shares of Common  Stock
theretofore issued and outstanding,  the number of shares which are reserved for
issuance  under the Plan and the  number  of shares  which,  at such  time,  are
subject  to Options  and with  respect to grants of  Restricted  Shares,  in the
number  and  kind  of  Shares  covered  thereby,  shall,  to the  extent  deemed
appropriate  by the  Committee  or Board,  as the case may be, be  increased  or
decreased in the same proportion,  provided, however, that the Company shall not
be obligated to issue fractional shares.

     Likewise,  in the event of any change in the  outstanding  shares of Common
Stock by reason of any recapitalization, merger, consolidation,  reorganization,
combination or exchange of shares or other  corporate  change,  the Committee or
Board shall make such  substitution  or  adjustments,  if any, as it deems to be
appropriate,  as to the  number  or kind of  shares  of  Common  Stock  or other
securities  which are  reserved  for  issuance  under the Plan and the number of

                                       4

shares or other  securities  which, at such time are subject to Options and with
respect to grants of Restricted Shares, in the number and kind of Shares covered
thereby.

     In the event of a Change in Control (a) all Options outstanding on the date
of such Change in Control shall become  immediately and fully  exercisable,  and
(b) an optionee  will be permitted to surrender  for  cancellation  within sixty
(60) days after such Change in Control any Option or portion of an Option  which
was granted more than six (6) months prior to the date of such surrender, to the
extent not yet  exercised,  and to receive a cash  payment in an amount equal to
the excess,  if any, of the Fair Market Value (on the date of  surrender) of the
shares of Common  Stock  subject to the Option or portion  thereof  surrendered,
over the aggregate  purchase price for such Shares under the Option; and (c) all
Restricted Shares shall become immediately vested.

1.8  Non-Alienation of Benefits
     --------------------------

     Except as herein  specifically  provided,  no right or unpaid benefit under
the Plan shall be subject to  alienation,  assignment,  pledge or charge and any
attempt to  alienate,  assign,  pledge or charge the same shall be void.  If any
Participant  or other person  entitled to benefits  hereunder  should attempt to
alienate,  assign,  pledge or charge any benefit  hereunder,  then such  benefit
shall, in the discretion of the Committee, cease.

1.9  Withholding or Deduction for Taxes
     ----------------------------------

     If, at any time,  the Company or any  Subsidiary  or Affiliate is required,
under applicable laws and regulations, to withhold, or to make any deduction for
any taxes, or take any other action in connection with any Option exercise,  the
Participant  shall be  required  to pay to the  Company  or such  Subsidiary  or
Affiliate, the amount of any taxes required to be withheld, or, in lieu thereof,
at the option of the Company,  the Company or such  Subsidiary  or Affiliate may
accept a  sufficient  number  of shares  of  Common  Stock to cover  the  amount
required to be withheld.

          Committee or Board shall not have the right to reprice any outstanding
          Options.

                                       5

          compensation  arrangements  for  employees  of  the  Company  or  such

          other member or by any officer, agent or employee.

     Notwithstanding  any other  provision of the Plan, the Company shall not be
obligated  to issue any shares of Common Stock upon the exercise of an option or
the vesting of  Restricted  Shares  granted  under the Plan, or grant any Option
with respect  thereto,  unless it is advised by counsel of its selection that it

the period during which the restrictions set forth in Section 3.2 shall apply to
such Restricted Shares (the "Restricted Period"). Unless otherwise determined by
the Committee,  the Restricted Period shall not be less than 36 nor more than 60
consecutive  months  commencing  with the  first  day of the  month in which the
Restricted Shares are granted. Subject to the provisions of Section 3.3, a grant

                                       8

of Restricted Shares shall be effective for the Restricted Period and may not be
revoked.

3.2  Restrictions
     ------------

     At the time of grant of Restricted  Shares to a Participant,  a certificate
representing the number of shares of Common Stock granted shall be registered in
his name and issued to the  Participant.  The Participant  shall have the entire
beneficial ownership interest in, and all rights and privileges of a stockholder
as to, such Restricted Shares,  including the right to receive dividends and the
right to vote such Restricted Shares, subject to the following restrictions: (i)
no unvested Restricted Shares may be sold,  transferred,  assigned,  pledged, or
otherwise  encumbered  or disposed  of during the  Restricted  Period;  and (ii)
vested Restricted Shares may only be sold,  transferred or otherwise disposed of
in  compliance  with  applicable  securities  laws.  In the event of a Change in
Control,  all  restrictions  set forth  above in this  Section as to  previously
granted Restricted Shares shall lapse.

3.3  Termination of Employment
     -------------------------

     (i)  Total  Disability or Death. If a Participant  ceases to be an employee
          prior to the end of a Restricted Period by reason of Total Disability,
          death,  all  Restricted  Shares  granted  to  such  Participant  shall
          immediately  vest in Participant or in his  beneficiary or estate,  as
          the case may be, and all restrictions  applicable to such shares shall
          lapse.

     (ii) All Other  Terminations.  If a  Participant  ceases to be an  employee
          prior to the end of a  Restricted  Period  for any  reason  other than
          death,  Total Disability or Change of Control,  the Participant  shall
          immediately   forfeit  all  Restricted  Shares  then  subject  to  the
          restrictions  of Section 3.2 hereof in accordance  with the provisions
          thereof,  except that the Committee or Board may, if it finds that the
          circumstances   in  the  particular   case  so  warrant,   allow  such
          Participant to retain any or all of the Restricted Shares then subject
          to the restrictions of Section 3.2 and all restrictions  applicable to
          such retained shares shall lapse.

3.4  Vesting of Restricted Shares
     ----------------------------

     At the end of the Restricted Period or at such earlier time as provided for
in  Section  3.3  hereof  or as  the  Committee  or  Board  may  determine,  all
restrictions  applicable to the Restricted Shares shall lapse,  except that such
shares may only be sold, transferred or otherwise disposed of in compliance with
applicable securities laws.
