with the Delaware Secretary of State of an appropriate  certificate of amendment
to such  Amended  and  Restated  Certificate  of  Incorporation  effecting  such

         2. Purpose of the Plan. The Plan is intended to encourage  ownership of
Stock by employees of the Company and any Related Corporations and to provide an
additional incentive for the employees to promote the success of the business of
the Company and any Related  Corporations.  It is intended that the Plan qualify
as an "employee  stock  purchase  plan" within the meaning of Section 423 of the
Code.

         3. Term of the Plan.  The Plan will become  effective on the  Effective
Date. No Option may be granted under the Plan after January 31, 2005.

         4.  Administration  of the Plan. The Plan will be  administered  by the
Board. The Board will determine which  semi-periods  will be Offering Periods in
accordance  with  Section  8, and which (if any)  Related  Corporations  will be
Employers as to each Offering Period. The Board will have authority to interpret
the Plan, to prescribe, amend, and rescind rules and regulations relating to the
Plan, to determine the terms of Options  granted under the Plan, and to make all
other determinations  necessary or advisable for the administration of the Plan.
All  determinations  of the Board under the Plan will be final and binding as to
all persons  having or claiming any interest in or arising out of the Plan.  The
Board may delegate all or any portion of its authority  with respect to the Plan
to the Committee,  and thereafter  until such delegation is revoked by the Board
all powers under the Plan  delegated to the  Committee  will be exercised by the
Committee.

         5.  Termination and Amendment of Plan. The Board may terminate or amend
the Plan at any  time;  provided,  however,  that  the  Board  may not,  without
approval  by the  holders  of a  majority  of the  outstanding  shares of Stock,
increase  the maximum  number of shares of Stock  purchasable  under the Plan or
change the description of employees or classes of employees eligible to receive





Options.  Without  limiting the generality of the foregoing,  but subject to the
foregoing proviso, the Board may amend the Plan from time to time to increase or
decrease  the length of any future  Offering  Periods  and to make all  required
conforming  changes to the Plan.  No  termination  or  amendment of the Plan may
adversely  affect the rights of a  Participating  Employee  with  respect to any
Option  held  by  the  Participating  Employee  prior  to  such  termination  or
amendment.

         6. Shares of Stock  Subject to the Plan.  No more than an  aggregate of
600,000  shares of Stock may be issued or delivered  pursuant to the exercise of
Options  granted  under the Plan  (such  maximum  number of shares  taking  into
account the effects of the  one-for-two  reverse stock split  referred to above,
and  subject to  automatic  proportionate  adjustment  in the event of any other
stock  dividend,  stock split,  stock  combination,  recapitalization,  or other
similar event  affecting the Common Stock and to adjustments  made in accordance
with Section 9.7). Shares to be delivered upon exercise of Options may be either
shares of Stock that are  authorized but unissued or shares of Stock held by the
Company  in its  treasury.  If an Option  expires or  terminates  for any reason
without  having been exercised in full,  the  unpurchased  shares subject to the
Option will become  available for other  Options  granted under the Plan. At all
times during which  Options are  outstanding,  the Company will reserve and keep
available  sufficient  shares  of Stock to cover  the  exercise  in full of such
Options,  and  will  pay all  fees  and  expenses  incurred  by the  Company  in
connection therewith.

         7. Persons  Eligible to Receive  Options.  Each employee of an Employer
will be  granted  an Option on each  Offering  Commencement  Date on which  such
employee meets all of the following requirements:

         (a) The employee is  customarily  employed by an Employer for more than
twenty hours per week and for more than five months per calendar year.

         (b) The  employee  will  not,  after  grant of the  Option,  own  Stock
possessing  five percent or more of the total combined  voting power or value of
all classes of stock of the Company or of any Related Corporation.  For purposes
of this  paragraph  (b),  the rules of Section  424(d) of the Code will apply in
determining the Stock ownership of the employee, and Stock that the employee may
purchase  under  outstanding  options  will be  treated  as  Stock  owned by the
employee.

         (c) Upon grant of the Option,  the employee's  rights to purchase Stock
under all employee  stock  purchase  plans (as defined in Section  423(b) of the
Code) of the  Company  and its  Related  Corporations  will not accrue at a rate
exceeding $25,000 of Market Value of Stock (determined as of the grant date) for





each calendar year in which such Option is  outstanding at any time. The accrual
of rights to  purchase  Stock will be  determined  in  accordance  with  Section
423(b)(8) of the Code.

         8. Offering  Commencement  Dates.  Options will be granted on the first
business day of the period  running from the Effective Date to January 31, 1996,
and of each  semi-annual  period  running from February 1 to the next  following
July 31 or from August 1 to the next following January 31, that is designated by
the Board as an Offering Period. Following the initial Offering Period under the
Plan (i.e., the period running from the Effective Date to January 31, 1996), all
succeeding  semi-annual  periods described above will be deemed Offering Periods
without need of further Board action unless and until contrary  action will have
been taken by the Board prior to the  beginning  of what would  otherwise  be an
Offering Period.

         9.       Terms and Conditions of Options.

         9.1 General. All Options granted on a particular Offering  Commencement
Date will comply with the terms and conditions set forth in Sections 9.2 through
9.11.  Subject to Sections  7(c) and 9.9,  each Option  granted on a  particular
Offering  Commencement Date will entitle the Participating  Employee to purchase
that  number of shares of Stock  equal to the result of $12,500  (or such lesser
amount  as  is  selected  by  the  Board,  prior  to  the  applicable   Offering
Commencement  Date,  and  applied  uniformly  during the  Offering  Period  then
beginning)  divided  by the  Market  Value  of one such  share  on the  Offering
Commencement  Date and then rounded  down,  if  necessary,  to the nearest whole
number.

         9.2 Purchase Price. The purchase price of each Option Share will be 85%
of the  lesser of (a) the  Market  Value of a share of Stock as of the  Offering
Commencement Date or (b) the Market Value of a share of Stock as of the Offering
Termination Date.

         9.3      Restrictions on Transfer.

         (a) Options may not be  transferred  otherwise than by will or pursuant
to  applicable  laws of  descent  and  distribution.  During the  lifetime  of a
Participating  Employee,  such  Participating  Employee's  Options  may  not  be
exercised by anyone other than such Participating Employee.

         (b) The Optionee will agree in the  Membership  Agreement to notify the
Company  of any  transfer  of Option  Shares  within  two years of the  Offering
Commencement  Date for such Option  Shares.  The Company  will have the right to
place a legend on all stock certificates representing Option Shares instructing





the transfer  agent to notify the Company of any transfer of such Option Shares.
The Company will also have the right to place a legend on all stock certificates
representing  Option  Shares  setting forth or referring to the  restriction  on
transferability of such Option Shares.

         9.4 Expiration. Each Option will expire at the close of business on the
Offering  Termination  Date  or on such  earlier  date as may  result  from  the
operation of Sections 9.5 or 9.6.

         9.5 Termination of Employment of Optionee. If a Participating  Employee
ceases for any reason  (other  than  death) to be  continuously  employed  by an
Employer, whether due to voluntary severance,  involuntary severance,  transfer,
or disaffiliation of a Related  Corporation with the Company,  his or her Option
will immediately  expire, and the Participating  Employee's  accumulated payroll
deductions will be returned by the Company.  For purposes of this Section 9.5, a
Participating  Employee  will be deemed to be employed  throughout  any leave of
absence for military service,  illness, or other bona fide purpose that does not
exceed the longer of ninety days or the period  during  which the  Participating
Employee's  reemployment  rights are  guaranteed by statute  (including  without
limitation the Veterans  Reemployment  Rights Act or similar statute relating to
military service) or by contract. If the Participating  Employee does not return
to  active  employment  prior  to the  termination  of such  period,  his or her
employment will be deemed to have ended on the ninety-first day of such leave of
absence (or such longer period  guaranteed by statute or by contract as provided
above).

         9.6 Death of Optionee.  If a  Participating  Employee  dies, his or her
Beneficiary   will  be  entitled  to  withdraw  the   Participating   Employee's
accumulated  payroll   deductions,   or  to  purchase  shares  on  the  Offering
Termination  Date to the  extent  that the  Participating  Employee  would be so
entitled had he or she  continued  to be employed by an Employer.  The number of
shares purchasable will be limited by the amount of the Participating Employee's
accumulated  payroll deductions as of the date of his or her death.  Accumulated
payroll  deductions will be applied by the Company toward the purchase of shares
only if the  Participating  Employee's  Beneficiary  submits to the Employer not
later than the Offering  Termination  Date a written request that the deductions
be so applied.  Accumulated  payroll  deductions not withdrawn or applied to the
purchase of shares will be delivered by the Company to the Beneficiary  within a
reasonable time after the Offering Termination Date.

        9.7 Capital  Changes  Affecting the Stock.  In  the event that,  between
the Offering  Commencement Date  and the Offering  Termination Date with respect
to an Option, a stock dividend is paid or becomes payable in respect of





the Stock,  or there occurs a split-up or contraction in the number of shares of
Stock,  the  number of shares of Stock for which the Option  may  thereafter  be
exercised  and  the  price  to  be  paid  for  each  such  share  will  both  be
proportionately  adjusted.  In the event that,  after the Offering  Commencement
Date, there occurs a  reclassification  or change of outstanding shares of Stock
or a consolidation or merger of the Company with or into another  corporation or
a sale or conveyance,  substantially as a whole, of the property of the Company,
the Participating  Employee will be entitled on the Offering Termination Date to
receive shares of Stock or other securities  equivalent in kind and value to the
shares of Stock he or she would have held if he or she had  exercised the Option
in full  immediately  prior  to such  reclassification,  change,  consolidation,
merger, sale, or conveyance and had continued to hold such shares (together with
all other shares and securities  thereafter issued in respect thereof) until the
Offering   Termination   Date.   In  the  event   that   there  is  to  occur  a
recapitalization  involving an increase in the par value of the Stock that would
result in a par value exceeding the exercise price under an outstanding  Option,
the Company will notify the  affected  Participating  Employee of such  proposed
recapitalization  immediately  upon its  being  recommended  by the Board to the
Company's  shareholders,  after which the  Participating  Employee will have the
right to  exercise  his or her  Option  prior to such  recapitalization;  if the
Participating  Employee fails to exercise the Option prior to  recapitalization,
the exercise price under the Option will be appropriately adjusted. In the event
that,  after the  Offering  Commencement  Date,  there occurs a  dissolution  or
liquidation  of the Company,  except  pursuant to a transaction to which Section
424(a) of the Code applies,  each Option will terminate,  but the  Participating
Employee  will  have  the  right to  exercise  his or her  Option  prior to such
dissolution or liquidation.

         9.8 Payroll  Deductions.  A Participating  Employee may purchase shares
under his or her Option during any particular  Offering Period by completing and
returning  to the  Company  at least  15 days  prior  to the  beginning  of such
Offering Period a Membership  Agreement indicating a percentage (which will be a
full integer  between two and ten,  inclusive)  of his or her Base  Compensation
that is to be withheld each pay period (not to exceed an aggregate of $12,500 in
any Offering Period). No Participating  Employee will be permitted to change the
percentage of Base Compensation withheld during an Offering Period. However, not
more than once per Offering Period the Participating  Employee may cancel his or
her  Agreement,  and  withdraw  all  (but  not  less  than  all)  of  his or her
accumulated payroll deductions,  by submitting a written request therefor to the
Company not later than the close of business on the Offering  Termination  Date.
The  percentage of Base  Compensation  withheld may be changed from one Offering
Period to another.

         9.9      Exercise  of  Options.  On  the Offering  Termination Date the
Participating  Employee may  purchase  the  number of  shares purchasable by his





or her accumulated payroll deductions,  or if less, the maximum number of shares
subject to the Option as provided in Section 9.1, provided that:

         (a) If the total number of shares that all Optionees elect to purchase,
together with any shares  already  purchased  under the Plan,  exceeds the total
number of shares that may be purchased under the Plan pursuant to Section 6, the
number of shares that each  Optionee is permitted to purchase  will be decreased
pro rata based on the Participating Employee's accumulated payroll deductions in
relation to all accumulated  payroll  deductions  currently being withheld under
the Plan.

         (b) If the  number of shares  purchasable  includes  a  fraction,  such
number will be adjusted to the next smaller whole number and the purchase  price
will be adjusted accordingly.

Accumulated  payroll deductions not withdrawn prior to the Offering  Termination
Date will be automatically  applied by the Company toward the purchase of Option
Shares, or to the extent in excess of the aggregate purchase price of the shares
then purchasable by the  Participating  Employee,  refunded to the Participating
Employee,  except that where such excess is less than the  purchase  price for a
single share of Stock on the Offering  Termination Date, such excess will not be
refunded  but instead will be carried over and applied to the purchase of shares
in the first following Offering Period (subject to the possibility of withdrawal
by the Participating Employee during such Offering Period in accordance with the
terms of the Plan).

         9.10 Delivery of Stock.  Except as provided below,  within a reasonable
time after the Offering  Termination  Date, the Company will deliver or cause to
be delivered to the Participating Employee a certificate or certificates for the
number of shares purchased by the  Participating  Employee.  A stock certificate
representing the number of Shares purchased will be issued in the  participant's
name only, or if his or her  Membership  Agreement so specifies,  in the name of
the  employee  and another  person of legal age as joint  tenants with rights of
survivorship. If any law or applicable regulation of the Securities and Exchange
Commission or other body having  jurisdiction  in the premises will require that
the Company or the Participating Employee take any action in connection with the
shares  being  purchased  under  the  Option,  delivery  of the  certificate  or
certificates  for such shares will be postponed until the necessary  action will
have  been  completed,  which  action  will be taken by the  Company  at its own
expense,  without  unreasonable  delay.  The  Optionee  will have no rights as a
shareholder  in  respect  of  shares  for  which  he or she has not  received  a
certificate.






         9.11 Return of Accumulated  Payroll  Deductions.  In the event that the
Participating  Employee  or  the  Beneficiary  is  entitled  to  the  return  of
accumulated  payroll  deductions,  whether  by reason of  voluntary  withdrawal,
termination of employment,  or death, or in the event that  accumulated  payroll
deductions exceed the price of shares purchased, such amount will be returned by
the Company to the  Participating  Employee or the Beneficiary,  as the case may
be, not later than within a reasonable  time following the Offering  Termination
Date  applicable  to the Option  Period in which  such  deductions  were  taken.
Accumulated  payroll  deductions  held by the Company will not bear interest nor
will the  Company  be  obligated  to  segregate  the same  from any of its other
assets.
