registered or qualified under the securities laws of any state,  the Company may
impose  restrictions  upon the sale,  pledge or other  transfer  of such  Common
Shares  (including the placement of appropriate  legends on stock  certificates)
if, in the  judgment of the  Company  and its  counsel,  such  restrictions  are
necessary or desirable in order to achieve  compliance  with the Securities Act,
the securities laws of any state or any other law or with  restrictions  imposed
by the Company's underwriters.

        B. Investment  Intent at Exercise.  In the event that the sale of Common
Shares  under  the  Plan  is not  registered  under  the  Securities  Act but an
exemption is available  which  requires an  investment  representation  or other
representation,  the Optionee shall  represent and agree at the time of exercise
that the Common  Shares being  acquired  upon  exercising  this option are being
acquired  for  investment,  and  not  with a view to the  sale  or  distribution
thereof;  and shall make such other  representations  as are deemed necessary or
appropriate by the Company and its counsel.

        C. Legend. In the event that  certificates  evidencing Common Shares are
acquired under this Agreement in an  unregistered  transaction,  they shall bear
the following  restrictive


                                       5.



legend (and such other  restrictive  legends as are required or deemed advisable
under the provisions of any applicable law):

        "THE  SHARES  REPRESENTED  HEREBY  HAVE NOT BEEN  REGISTERED  UNDER  THE
        SECURITIES ACT OF 1933, AS AMENDED,  AND  MAY NOT BE SOLD,  PLEDGED,  OR
        OTHERWISE  TRANSFERRED WITHOUT AN EFFECTIVE  REGISTRATION  THEREOF UNDER
        SUCH ACT OR AN OPINION OF COUNSEL,  SATISFACTORY  TO THE COMPANY AND ITS
        COUNSEL, THAT SUCH REGISTRATION IS NOT REQUIRED."

        D.  Removal  of  Legends.  If, in the  opinion  of the  Company  and its
counsel,  any legend placed on a stock  certificate  representing  Common Shares
sold under this Agreement is no longer required,  the holder of such certificate
shall be entitled to exchange such  certificate  for a certificate  representing
the same number of Common Shares but lacking such legend.

        E.  Administration.  Any determination by the Company and its counsel in
connection  with  any of the  matters  set  forth  in this  Section  IX shall be
conclusive and binding on the Optionee and all other persons.

X.      Tax Withholdlng.

        A. At the time Optionee  exercises this option,  in whole or in part, or
at any time thereafter as requested by the Company,  Optionee hereby  authorizes
withholding  from  payroll  and any  other  amounts  payable  to  Optionee,  and
otherwise  agrees  to make  adequate  provision  for  (including  by  means of a
"cashless  exercise"  pursuant  to a program  developed  under  Regulation  T as
promulgated  by the  Federal  Reserve  Board  to  the  extent  permitted  by the
Company), any sums required to satisfy the federal, state, local and foreign tax
withholding  obligations of the Company or an Affiliate,  if any, which arise in
connection with the option.

        B. Upon the  Optionee's  request and subject to approval by the Company,
in its sole  discretion,  and  compliance  with  any  applicable  conditions  or
restrictions of law, the Company may withhold from fully vested shares of Common
Stock otherwise issuable to Optionee upon the exercise of the option a number of
whole  shares of Common  Stock  having a Fair Market  Value,  determined  by the
Company as of the date of exercise,  which satisfies  federal,  state, local and
foreign  tax  obligations  of the Company and the  Optionee;  provided  that the
Company  shall not  withhold  shares  of Common  Stock at rates in excess of the
minimum  statutory  withholding  rates  imposed upon the Company for federal and
state tax purposes if such withholding would result in a charge to the Company's
earnings  for  accounting  purposes.  If the  date of  determination  of any tax
withholding  obligation is deferred to a date later than the date of exercise of
the option,  share withholding  pursuant to the preceding  sentence shall not be
permitted unless Optionee makes a proper and timely election under Section 83(b)
of the Code,  covering the aggregate  number of shares of Common Stock  acquired
upon such  exercise  with  respect  to which  such  determination  is  otherwise
deferred, to accelerate the determination of such tax withholding  obligation to
the date of exercise of the option. Notwithstanding the filing of such election,
shares of Common Stock shall be withheld  solely from fully vested  shares of


                                       6.



Common  Stock  determined  as of the date of  exercise  of the  option  that are
otherwise issuable to Optionee upon such exercise.  Any adverse  consequences to
Optionee  arising in connection with such share  withholding  procedure shall be
Optionee's sole responsibility.

        C.  Optionee may not  exercise  this option  unless the tax  withholding
obligations  of the Company  and/or any  Affiliate are  satisfied.  Accordingly,
Optionee  may not be able to exercise  the option when  desired  even though the
option  is  vested,  and  the  Company  shall  have  no  obligation  to  issue a
certificate  for such  shares of Common  Stock or release  such shares of Common
Stock from any escrow provided for herein.

XI.     Miscellaneous Provisions.

        A.  Reservation of Rights.  Except as provided in the Plan, the Optionee
shall have no rights by reason of (l) any subdivision or consolidation of shares
of stock of any class, (2) the payment of any dividend or (3) any other increase
or  decrease  in the  number of shares of stock of any  class.  Any issue by the
Company of shares of stock of any class, or securities  convertible  into shares
of stock of any class,  shall not affect,  and no adjustment  by reason  thereof
shall be made with respect to, the number or Exercise Price of the Common Shares
subject to this option. The grant of this option shall not affect in any way the
right  or  power  of  the  Company  to  make   adjustments,   reclassifications,

business or assets.

        B. Rights As a  Stockholder.  Neither the  Optionee  nor the  Optionee's

Shares  subject to this option until such Common  Shares have been issued in the
name of the Optionee or the Optionee's representative.

giving the  Optionee  the right to be  retained as a Key  Employee.  The Company

without cause (subject to any employment  agreement between the Optionee and the
Company).
