         AND WHEREAS, in light of the above, the Company desires to grant to the
Participant a Nonqualified Stock Option to purchase shares of Company common
stock under the Company's Amended and Restated 1993 Long-Term Incentive Plan.

         NOW, THEREFORE, in consideration of these premises, the parties agree
that the following shall constitute the Agreement between the Company and the
Participant:

         1.       Definitions.  For purposes of this Agreement,  the terms used
                  -----------
                  herein shall have the meanings  specified in the Plan, a copy
                  of which is attached hereto and incorporated herein by
                  reference pursuant to Section 10 below.

         2.       Grant of Nonqualified Stock Option. Subject to the terms and
                  ----------------------------------
                  conditions set forth herein, the Company grants to the
                  Participant a Nonqualified Stock Option to purchase from the
                  Company [# of Shares] Shares at an Option Price of [US$00.00]
                  per share, subject to adjustment as provided in Section 8
                  hereof. This Option shall vest and become exercisable as
                  follows: (a) as to [QtrShr] shares any time after December 7,
                  2002, and (b) an additional [1/48Share] shares after the [day]
                  day of each month thereafter for the next 36 months until this
                  option is fully vested (i.e., 100% vested in four years).

This Option shall expire on [month day, year]; provided, however, that (i) if
                                               --------  -------
the Participant's employment with the Company is terminated prior to the
exercise in full of this Option, then the rules of Section 7 hereof shall apply,
and (ii) notwithstanding anything to the contrary herein, the Company shall not
be required to issue or transfer any certificates for Shares purchased upon
exercise of this Option until all applicable requirements of law have been
complied with and, if applicable, such Shares shall have been duly listed on any
securities exchange on which Shares may then be listed.

         3.       Notice of Exercise. This Option may be exercised in whole or
                  ------------------
in part, from time to time, in accordance with Section 2 by the delivery of
written notice to the Vice President of Human Resources of the Company at the
address provided in Section 13, which notice shall:

         (a)      specify the number of Shares to be purchased and the total
                  Option Price to be paid therefor;

         (b)      if the person exercising this Option is not the Participant
                  himself or herself, contain or be accompanied by evidence
                  satisfactory to the Committee of such person's right to
                  exercise this Option; and

<PAGE>

         (c)      be accompanied by payment in full of the Option Price (i) in
                  cash or its equivalent, or (ii) with the Committee's consent,
                  by tendering previously acquired Shares having a Fair Market
                  Value at the time of exercise equal to the Option Price
                  (provided such previously acquired Shares have been held by
                  the Participant for at least 6 months prior to such tender),
                  (iii) with the Committee's consent, by a combination of cash
                  and such tendered Shares, or (iv) with the Committee's
                  consent, through a cashless exercise as permitted under
                  Federal Reserve Board Regulation T or by any other means which
                  the Committee deems consistent with the Plan and applicable
                  law.

As soon as practicable after receipt of an exercise notice and full payment of
the Option Price, the Company shall deliver to the Participant, in the
Participant's name, Share certificates in an appropriate amount based upon the
number of Shares purchased upon the exercise. The Committee may impose such
restrictions on any Shares acquired pursuant to an exercise as it deems
advisable, including without limitation restrictions under applicable Federal
securities laws, under the requirements of any stock exchange or market upon
which such Shares are then listed and/or traded, and under blue sky or state
securities laws applicable to such Shares.

         4.       Transfer and Exercise of Option. This Option shall not be
                  -------------------------------
sold, transferred, pledged, assigned, or otherwise alienated or hypothecated,
other than by will or by the laws of descent and distribution. During the
Participant's lifetime, this Option may be exercised only by him or her. In
accordance with the provisions of the Plan, the Participant may, from time to
time, name any beneficiary or beneficiaries (who may be named contingently or
successively) who shall be entitled to exercise this Option in the event of the
Participant's death and to the extent this Option is exercisable at that time.
In the absence of any such designation, this Option may be exercised, to the
extent exercisable, by the administrator of the Participant's estate.

         5.       Status of Participant.  The Participant shall not be deemed a
                  ---------------------
stockholder of the Company with respect to any of the Shares subject to this
Option, except to the extent that such Shares shall have been purchased and
transferred to him.

         6.       No Effect on Capital Structure. This Option shall not affect
                  ------------------------------
the right of the Company or any Subsidiary thereof to reclassify, recapitalize
or otherwise change its capital or debt structure or to merge, consolidate,
convey any or all of its assets, dissolve, liquidate, windup, or otherwise
reorganize.

         7.       Premature Expiration of Option.
                  ------------------------------

         7.1      Termination of Employment Other Than For Cause. (a) If the
                  ----------------------------------------------
employment of the Participant shall terminate for any reason other than Cause,
this Option, to the extent (if any) it is not yet exercisable, shall terminate
immediately and be forfeited to the Company; provided, however, that if the
employment of the Participant shall terminate by reason of death, disability or
retirement and further that this Option has been held by the Participant for at
least six (6) months from the date of grant at the time of such termination,
this Option, to the extent it is not yet exercisable, shall immediately vest and
remain exercisable until the earlier to occur of one (1) year from the date of
termination or the scheduled expiration date of this Option; and provided
further that the Committee, in its sole discretion, shall have the right to
immediately vest, upon any other termination without Cause, all or any portion
of this Option, subject to such terms as the Committee, in its sole discretion,
deems appropriate, provided that the maximum exercise period which may be
permitted upon any such acceleration of vesting shall be the shorter of one year
or the scheduled expiration date of this Option.

                  (b)  To the extent that this Option is exercisable as of the
effective date of a termination other than for Cause, this Option may be
exercised by the Participant within the period beginning on the effective date
of termination and ending on the earlier to occur of the scheduled expiration
date of the Option or: (i) one year following the effective date of termination
in the case of termination by reason of death, disability or retirement, and
(ii) three months following such date in the case of termination for any other
reason (other than for Cause).

         7.2      Termination of Employment For Cause. If the employment of the
                  -----------------------------------
Participant shall terminate for Cause, this Option shall terminate immediately
and be forfeited to the Company, and no additional exercise period shall be
allowed, regardless of the exercisability of this Option at the time of such
termination.

         8.       Adjustments Upon Changes in Capitalization, Merger, Etc.
                  -------------------------------------------------------
Notwithstanding any other provision herein, in the event of any merger,
reorganization, consolidation, recapitalization, separation, liquidation, stock

                                      2

<PAGE>

dividend, split-up, share combination, or other change in the corporate
structure of the Company affecting the Shares, such adjustment shall be made in
the number and class of Shares subject to this Option and the Option Price as
may be determined by the Committee, in its sole discretion, to be appropriate
and equitable to prevent dilution or enlargement of rights, provided that any
fractional share resulting from such adjustment shall be eliminated.

         9.       Committee Authority. Any question concerning the
                  -------------------
interpretation of this Agreement, any adjustments required to be made under
Section 8 of this Agreement, and any controversy which may arise under this
Agreement shall be determined by the Committee, in its sole discretion, which
determination shall be final, conclusive and binding on all Persons, including
without limitation the Company and the Participant.

         10.      Plan Controls. The terms of this Agreement are governed by the
                  -------------
terms of the Plan, a copy of which is attached hereto as Exhibit A and made a
part hereof as if fully set forth herein, and in the case of any inconsistency
between the terms of this Agreement and the terms of the Plan, the terms of the
Plan shall control.

         11.      Change In Control. Upon the occurrence of a Change in Control,
                  -----------------
unless otherwise specifically prohibited by law, this Option shall become
immediately exercisable and shall remain as such for the duration of its term;
provided, however, the Committee shall have authority to make any modifications
to this Option which are consistent with the provisions of the Plan and
determined by the Committee to be appropriate before the effective date of the
Change in Control.

         12.      Tax Withholding. The Company shall have the power and right to
                  ---------------
deduct or withhold, or require the Participant to remit to the Company, an
amount sufficient to satisfy Federal, state and local taxes required by law to
be withheld with respect to the grant of this Option, its exercise or any
payment made under or as a result of this Option or the Plan. The Participant
may elect, subject to the approval of the Committee, to satisfy this withholding
requirement, in whole or in part, by having the Company withhold Shares having a
Fair Market Value on the date the tax is to be determined equal to the minimum
marginal total tax which could be imposed on the transaction. Any such election
shall be irrevocable, made in writing, signed by the Participant and comply with
one of the following requirements:

         (a)      Written  notice of the withholding election is delivered to
                  the  Committee  at least six months prior to the date
                  specified by the Participant on which the Option exercise is
                  to occur; or

         (b)      The withholding election is made in connection with an Option
                  exercise which occurs during a Window Period.
