          --------
such date or dates and during such period and for such number of shares as shall
be determined pursuant to the provisions of the instrument evidencing such
Option.  The Committee shall have the right to accelerate the date of exercise
of any option, provided that, the Committee shall not accelerate the exercise
date of any Incentive Stock Option granted if such acceleration would violate
the annual vesting limitation contained in Section 422(d)(1) of the Code.

     6.2  Notice of Exercise.  A person electing to exercise an Option shall
          ------------------

received by the Corporation.  Such payment may be made in whole or in part in
cash or, to the extent permitted by the Committee at or after the grant of an
Option, by delivery of a note or shares of the stock owned by the optionee,
including Restricted Stock, valued at their fair market value on the date of
delivery, or such other lawful consideration as the Committee may determine.
Until such person has been issued a certificate or

                                       8

 
certificates for the shares so purchased, he or she shall possess no rights of a
record holder with respect to any of such shares.

granted to a person who is, on the date of the grant, an Employee of the
Corporation or an Affiliated Corporation, shall be affected by any change of
duties or position of the optionee (including transfer to or from an Affiliated
Corporation), so long as he or she continues to be an Employee.  Employment

of absence (such as those attributable to illness, military obligations or
governmental service) provided that the period of such leave does not exceed 90
days or, if longer, any period during which such optionee's right to
reemployment is guaranteed by statute.  A bona fide leave of absence with
the written approval of the Committee shall not be considered an interruption of
employment under the Plan, provided that such written approval contractually
obligates the Corporation or any Affiliated Corporation to continue the
employment of the optionee after the approved period of absence.  If the
optionee shall cease to be an Employee for any reason other than death, such
Option shall thereafter be exercisable only to the extent of the purchase
rights, if any, which have accrued as of the date of such cessation; provided
that (i) the Committee may provide in the instrument evidencing any Option that
the Committee may in its absolute discretion, upon any such cessation of
employment, determine (but be under no obligation to determine) that such
accrued purchase rights shall be deemed to include additional shares covered by
such Option; and (ii) unless the Committee shall otherwise provide in the
instrument evidencing any Option, upon any such cessation of employment, such
remaining rights to purchase shall in any event terminate upon the earlier of
(A) the expiration of the original term of the Option; or (B)

Expiration of three months from such date. For purposes of the Plan, the term
"disability" shall mean "permanent and total disability" as defined in Section
22(e)(3) of the Code.

           -----------------

shall have acquired, by will or by the laws of descent and distribution, the
right to exercise any Options theretofore granted, may unless otherwise provided
by the Committee in any instrument evidencing any Option, exercise such Options
at any time prior to one year from the date of death; provided, that such Option
or Options shall expire in all events no later than the last day of the original
term of such Option; provided, further, that any such exercise shall be limited
to the purchase rights that have accrued as of the date when the optionee ceased

                                       11

 
Corporation, or an Affiliated Corporation, except as the Committee may from time
to time expressly provide. Neither the Plan, an Option or any instrument
evidencing an option confers upon any Employee the right to continued employment
with the Corporation or an Affiliated Corporation.


                                   ARTICLE X

               Amendment, Suspension or Termination of the Plan

     The Board may suspend the Plan or any part thereof at any time or may
terminate the Plan in its entirety.  Awards shall not be granted after Plan
termination.

     The Board may also amend the Plan from time to time, except that amendments
which affect the following subjects must be approved by stockholders of the
Corporation.

     (a)  Except as provided in Article XI relative to capital changes, the
number of shares as to which Options may be granted pursuant to Article V;

     (b)  The maximum term of Options granted;

     (c)  The minimum price at which Options may be granted;

     (d)  The term of the Plan; and

     (e)  The requirements as to eligibility for participation in the Plan.

     Awards granted prior to suspension or termination of the Plan may not be
canceled solely because of such suspension or termination, except with the
consent of the grantee of the Award.


                                  ARTICLE XI

                         Changes in Capital Structure

     The instruments evidencing options granted hereunder shall be subject to
adjustment in the

                                       12

 
event of changes in the outstanding Stock of the Corporation by reasonable of
stock dividends, stock splits, recapitalizations, reorganizations, mergers,
consolidations, combinations, exchanges or other relevant changes in
capitalization occurring after the date of an Award to the same extent as would
affect an actual share of stock issued and outstanding on the effective date of
such change. Such adjustment to outstanding Options shall be made without change
in the total price applicable to the unexercised portion of such options, and a
corresponding adjustment in the applicable option price per share shall be made.
In the event of any such change, the aggregate number and classes of shares for
which Options may thereafter be granted under Section 5.1 of this Plan may be
appropriately adjusted as determined by the Committee so as to reflect such
change.

     Notwithstanding the foregoing, any adjustments made pursuant to this
Article XI with respect to Incentive Stock Options shall be made only after the
Committee, after consulting with counsel for the Corporation, determines whether
such adjustments would constitute a "modification" of such Incentive Stock
Options (as that term is defined in Section 425 of the Code) or would cause any
adverse tax consequences for The holders of such Incentive Stock Options.  If
the Committee determines that such adjustments made with respect to Incentive
Stock Options would constitute a modification of such Incentive Stock Options,
it may refrain from making such adjustments.

     In the event of the proposed dissolution or liquidation of the Corporation,
each Option will terminate immediately prior to the consummation of such
proposed action or at such other time and subject to such other conditions as
shall be determined by the Committee.

     Except as expressly provided herein, no issuance by the Corporation of
shares of stock of any class, or securities convertible into shares of stock of
any class, shall affect, and no adjustment by reason thereof shall be made with
respect to, the number or price of shares subject to Options. No

                                       13

 
adjustments shall be made for dividends paid in cash or in property other than
securities of the Corporation.

     No fractional shares shall be issued under the Plan and the optionee shall
receive from the Corporation cash in lieu of such fractional shares.


                                  ARTICLE XII

                      Effective Date and Term of the Plan

     The Plan shall become effective on May 28, 1993. The Plan shall continue
until such time as it may be terminated by action of the Board; provided,
however, that no Options may be granted under this Plan on or after the tenth
anniversary of the effective date hereof.


                                  ARTICLE XIII

                Conversion of ISO's into Non-Qualified Options;

                              Termination of ISO's

     The Committee, at the written request of any optionee, may in its
discretion take such actions as may be necessary to convert such optionee's
Incentive Stock Options, that have not been exercised on the date of conversion,
into Non-Qualified Options at any time prior to the expiration of such Incentive
Stock Options, regardless of whether the optionee is an employee of the
Corporation or an Affiliated Corporation at the time of  such conversion.  Such
actions may includes but not be limited to, extending the exercise period or
reducing the exercise price of such Options.  At the time of such conversion,
the Committee (with the consent of the optionee) may impose such conditions on
the exercise of the resulting Non-Qualified Options as the Committee in its
discretion may determine,

                                       14

 
Provided that such conditions shall not be inconsistent with the Plan. Nothing
in the Plan shall be deemed to give any optionee the right to have such
optionee's Incentive Stock Options converted into Non-Qualified options, and no
such conversion shall occur until and unless the Committee takes appropriate
action. The Committee, with the consent of the optionee, may also terminate any
portion of any Incentive Stock Option that has not been exercised at the time of
such termination.


                                  ARTICLE XIV

                              Application of Funds

     The proceeds received by the Corporation from the sale of shares pursuant
to Options granted under the Plan shall be used for general corporate purposes.


                                  ARTICLE XV

                            Governmental Regulation

     The Corporation's obligation to sell and deliver shares of Stock under this
Plan is subject to the approval of any governmental authority required in
connection with the authorization, issuance or sale of such shares.


                                  ARTICLE XVI

                     Withholding of Additional Income Taxes

     Upon the exercise of a Non-Qualified Option or the making of a
Disqualifying Disposition (as defined in Article XVI) the Corporation, in
accordance with Section 3402(a) of the Code, may require the optionee to pay
additional withholding taxes in respect of the amount that is considered

                                       15

 
compensation includible in such person's gross income.  The Committee in its
discretion may condition the exercise of an Option on the payment of such
additional withholding taxes.


                                 ARTICLE XVII

                Notice to Company of Disqualifying Disposition

     Each employee who receives an Incentive Stock Option must agree to notify
the Corporation in writing immediately after the employee makes a Disqualifying
Disposition of any Stock acquired pursuant to the exercise of an Incentive Stock
Option. A Disqualifying Disposition is any disposition (including any sale) of
such Stock before the later of (a) two years after the date the employee was
granted the Incentive Stock Option or (b) one year after the date the employee
acquired Stock by exercising the Incentive Stock Option. If the employee
has died before such stock is sold, these holding period requirements do not
apply and no Disqualifying Disposition can occur thereafter.


                                 ARTICLE XVIII

                          Governing Law; Construction

     The validity and construction of the Plan and the instruments evidencing
Options shall be governed by the laws of the State of Delaware. In construing
this Plan, the singular shall include the plural and the masculine gender shall
include the feminine and neuter, unless the context otherwise requires.
