          as to:                                        any time after:
                             Shares                       /  /
                       -----                            -- -- --

                       -----                            -- -- --
</TABLE>

          This Option shall expire on __/__/____; 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 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 the law have been compiled 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 Corporate Secretary 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, (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 Normal Retirement (as defined below)
                    and provided 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 Normal Retirement, and (ii) three months
                    following such date in the case of termination for any other
                    reason (other than for Cause).

               (c)  As used herein, "Normal Retirement" shall mean Retirement at
                    or after the Participant's Normal
<PAGE>
                    Retirement Age under the Company's tax-qualified retirement
                    plan.

          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 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:

                    to occur; or

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

     hereunder, such notice shall be given to the non-notifying party via hand
