the terms and conditions  upon which such Stock Options may be exercised  and/or
transferred,  including the exercise of Stock  Options in connection  with other
awards made, or compensation  paid, to the  Participant;  (vi) make or alter any
restrictions  and  conditions  upon such Stock Options and the Stock received on
exercise  thereof,  including,  but not limited to, providing for limitations on
the Participant's right to keep any Stock received on termination of employment;
(vii)  determine  whether the  Participant or the  Corporation  has achieved any
goals or otherwise  satisfied any conditions or requirements that may be imposed

regulations,  establish,  define and/or  interpret these and any other terms and

         (c)  Applicable  Law.  This 1997 Plan and all  Stock  Options  shall be

        SECTION IV.  TERMS OF STOCK OPTIONS.

        (a) Agreements.  Stock Options shall be evidenced by a written agreement
between the  Corporation  and the  Participant  awarded the Stock  Option.  This
agreement  shall be in such form,  and contain  such terms and  conditions  (not
inconsistent with this 1997 Plan) as the Committee may determine.  The agreement
shall  include the following or a similar  statement:  "This stock option is not
intended to be an Incentive  Stock Option,  as that term is described in Section
422 of the Internal Revenue Code of 1986, as amended."

         (b) Term.  Stock Options shall be for such periods as may be determined
by the Committee.

        (c) Purchase Price. The purchase price of shares  purchased  pursuant to
any Stock Option shall be determined by the Committee,  and shall be paid by the
Participant or other person  permitted to exercise the Stock Option in full upon
exercise,  (i) in cash,  (ii) by delivery of shares of Common  Stock  (valued at
their Fair Market Value on the date of such exercise),  (iii) any other property
(valued  at its Fair  Market  Value on the date of such  exercise),  or (iv) any
combination of cash, stock and other property, with any payment made pursuant to
subparagraphs  (ii),  (iii) or (iv) only as permitted by the  Committee,  in its
sole  discretion.  In no event will the  purchase  price of Common Stock be less
than the par value of the Common Stock.

        (d) Restrictions.  At the discretion of the Committee,  the Common Stock
issued  pursuant  to the Stock  Options  granted  hereunder  may be  subject  to
restrictions on vesting or transferability. For the purposes of this limitation,
options shall be taken into account in the order granted.


                                      -3-






        (e) Withholding of Taxes.  Pursuant to applicable federal,  state, local
or foreign  laws,  the  Corporation  may be required to collect  income or other
taxes upon the grant of a Stock  Option to, or exercise of a Stock  Option by, a
holder.  The Corporation may require,  as a condition to the exercise of a Stock
Option, or demand, at such other time as it may consider  appropriate,  that the
Participant  pay the  Corporation  the amount of any taxes which the Corporation
may determine is required to be withheld or collected, and the Participant shall
comply with the requirement or demand of the Corporation. In its discretion, the
Corporation  may withhold  shares to be received upon exercise of a Stock Option
if it deems this an appropriate method for withholding or collecting taxes.

        (f) Securities Law Compliance.  Upon exercise (or partial exercise) of a
Stock  Option,  the  Participant  or other holder of the Stock Option shall make
such  representations  and furnish  such  information  as may, in the opinion of
counsel for the  Corporation,  be appropriate to permit the Corporation to issue
or transfer  Stock in compliance  with the  provisions of applicable  federal or
state  securities  laws. The  Corporation,  in its discretion,  may postpone the
issuance and delivery of Stock upon any exercise of this Option until completion
of such registration or other  qualification of such shares under any federal or
state  laws,  or  stock  exchange  listing,  as  the  Corporation  may  consider
appropriate.  Furthermore,  the  Corporation  is not  obligated  to  register or
qualify the shares of Common Stock to be issued upon  exercise of a Stock Option
under  federal or state  securities  laws (or to register or qualify them at any
time  thereafter),  and it may  refuse  to issue  such  shares  if,  in its sole
discretion,  registration  or exemption  from  registration  is not practical or
available. The Corporation may require that prior to the issuance or transfer of
Stock upon  exercise of a Stock  Option,  the  Participant  enter into a written
agreement to comply with any  restrictions  on subsequent  disposition  that the
Corporation deems necessary or advisable under any applicable  federal and state
securities  laws.  Certificates  of Stock issued  hereunder  shall bear a legend
reflecting such restrictions.

        (g) Right to Stock Option.  No employee of the  Corporation or any other
person shall have any claim or right to be a participant in this 1997 Plan or to
be granted a Stock Option hereunder. Neither this 1997 Plan nor any action taken
hereunder  shall be  construed  as giving any person any right to be retained in
the employ of the Corporation. Nothing contained hereunder shall be construed as
giving  any  person  any  equity or  interest  of any kind in any  assets of the
Corporation or creating a trust of any kind or a fiduciary  relationship  of any
kind between the Corporation and any such person. As to any claim for any unpaid
amounts under this 1997 Plan, any person having a claim for payments shall be an
unsecured creditor.

        (h) Indemnity. Neither the Board of Directors nor the Committee, nor any
members  of  either,  nor  any  employees  of the  Corporation  or  any  parent,
subsidiary,  or  other  affiliate,  shall  be  liable  for  any  act,  omission,
interpretation,  construction or determination  made in good faith in connection
with their  responsibilities with respect to this 1997 Plan, and the Corporation
hereby 



                                      -4-






agrees to indemnify  the members of the Board of  Directors,  the members of the
Committee,  and the employees of the  Corporation and its parent or subsidiaries
in respect of any claim, loss, damage, or expense (including  reasonable counsel
fees)  arising  from any such act,  omission,  interpretation,  construction  or
determination to the full extent permitted by law.

        (i)  Participation  by Foreigners.  Without amending this 1997 Plan, the
Committee may modify grants made to  participants  who are foreign  nationals or
employed outside the United States so as to recognize  differences in local law,
tax policy, or custom.

       SECTION V.  AMENDMENT AND TERMINATION: ADJUSTMENTS UPON CHANGES IN STOCK.

        The Board of Directors of the Corporation may at any time, and from time
to time,  amend,  suspend or  terminate  this 1997 Plan or any portion  thereof,
provided that no amendment shall be made without  approval of the  Corporation's
stockholders  if such approval is necessary to comply with any applicable  rules
or regulations of the Securities and Exchange  Commission,  including Rule 16b-3
(or any successor rule thereunder), or the rules and regulations of any exchange
or stock  market on which the  Corporation's  securities  are  listed or quoted.
Except as provided herein, no amendment,  suspension or termination of this 1997
Plan may  affect  the rights of a  Participant  to whom a Stock  Option has been
granted without such Participant's  consent. If there shall be any change in the
Common Stock or to any Stock Option granted under this 1997 Plan through merger,
consolidation, reorganization,  recapitalization, stock dividend, stock split or
other  change  in  the  corporate  structure  of  the  Corporation,  appropriate
adjustments  may be  made by the  Committee  (or if the  Corporation  is not the
surviving  corporation  in any such  transaction,  the Board of Directors of the
surviving  corporation,  or its  designee) in the  aggregate  number and kind of
shares  subject  to this 1997  Plan,  and the  number and kind of shares and the
price  per  share  subject  to  outstanding  options.  In  connection  with  the
foregoing, the Committee may issue new Stock Options in exchange for outstanding
Stock Options.

        SECTION VI.  SHARES OF STOCK SUBJECT TO THE PLAN.

        The number of shares of Common  Stock that may be the  subject of awards
under this 1997 Plan shall not exceed an aggregate of 1,000,000  shares.  Shares
to be  delivered  under  this 1997 Plan may be either  authorized  but  unissued
shares of Common  Stock or  treasury  shares.  Any  shares  subject to an option
hereunder  which for any reason  terminates,  is cancelled or otherwise  expires
unexercised,  and any shares  reacquired by the  Corporation due to restrictions
imposed on the shares,  shares  returned  because  payment is made  hereunder in
stock of equivalent value rather than in cash,  and/or shares  reacquired from a
recipient for any other reason shall,  at such time, no longer count towards the
aggregate  number of shares which have been the subject of Stock Options  issued
hereunder,  and such number of shares  shall be subject to further  awards under
this 1997 Plan,  provided,  first, that the total number of shares then eligible
for award under



                                      -5-






this 1997 Plan may not exceed the total  specified in the first sentence of this
Section  VI, and  second,  that the number of shares  subject to further  awards
shall not be  increased  in any way that would cause this 1997 Plan or any Stock
Option to not comply with Section 16, if applicable to the Corporation.

        SECTION VII.  EFFECTIVE DATE AND TERM OF THIS PLAN.

        The  effective  date of this 1997 Plan is March 1, 1997 (the  "Effective
Date")  and  awards  under  this 1997 Plan may be made for a period of ten years
