of a grant of a nonqualified stock option to purchase the shares of the common
stock of the Company (the "Option Shares") made to you, the Optionee named on
the first page of this Agreement, pursuant to the Plan. Attached is a copy of
the Plan, which is incorporated in this Agreement by reference and made a part

Internal Revenue Code of 1986, as amended.

         2.  Exercisability and Vesting of Option. The Option may be exercised
only to the extent the Option shall have vested in accordance with this
Agreement. The Option shall vest and become exercisable in accordance with the
terms of this Section 2.

         (a) General Rule. Except as otherwise provided in this Section 2, the
Option shall vest and be exercisable in accordance with the vesting schedule set
forth on the first page of this Agreement, provided that on each vesting date
you are then, and have been since the date of grant ("Grant Date"), continuously
employed by the Company or an "Affiliated Employer". For purposes of this
Agreement, an "Affiliated Employer" shall mean a subsidiary of the Company of
which the Company owns more than 50% of the outstanding common stock.

         (b) Death or Disability, Retirement or Change in Control.
Notwithstanding anything contained in this Agreement to the contrary, the Option
shall vest and become exercisable as to 100% of the Option Shares upon the
occurrence, prior to the date on which you cease to be an employee of the
Company or an Affiliated Employer (your "Employment Termination Date"), of (i)
your death or disability (as defined in Section 3(c) below); (ii) your
retirement (as defined in Section 3(d) below); or (iii) a Change in Control (as
defined in the Plan).

         (c) Effect of Other Termination of Employment. Notwithstanding anything
contained in this Agreement to the contrary, the portion of the Option that has
not previously vested prior to your Employment Termination Date shall cease to
vest, be immediately forfeited to the Company and cancelled if the Employment
Termination Date occurs for any other reason than the reasons specified in
Section 2(b) (i), (ii) or (iii) above.


         3.  Termination of Option. The date on which the Option shall terminate
in whole or in part as provided in this Section 3 is hereinafter referred to as
the "Option Termination Date". This Option shall terminate on the date that is
the earliest of:

         (a) the Expiration Date of the Option set forth on the first page of
this Agreement; or

         (b) three months after your Employment Termination Date if the
Employment Termination Date occurs for any reason other than the reasons
specified in Sections 3(c), 3(d), 3(e) or 3(f); or

         (c) one year after your Employment Termination Date if the Employment
Termination Date occurs by reason of your death or disability. For purposes of
this Agreement, "disability" shall mean that you are receiving disability
benefits under the Company's Long Term Disability Coverage, as then in effect,
on the Employment Termination Date; or

         (d) eighteen months after your Employment Termination Date if the
Employment Termination Date occurs by reason of your retirement, subject to
Section 3(f) below, provided that the retirement date occurs at least one year
after the date of grant. For purposes of this Agreement, (i) if you are a
non-employee director of the Company, then "retirement" shall mean the date on
which you cease to serve as a director of the Company, and (ii) if you are an
employee of the Company or an Affiliated Employer, then "retirement" shall mean
the termination of your employment with the Company or an Affiliated Employer

Company or an Affiliated Employer comprising at least 20 hours per week; or

Employer for "cause" (as defined below). For the purposes of this Agreement,
"cause" shall mean (i) the commitment of a felony or any crime involving moral
turpitude by you that is materially injurious to the Company or (ii) in carrying
out your duties, you intentionally engage in conduct that constitutes gross
neglect or gross misconduct that is materially injurious to the Company. You
shall be considered to have been discharged for cause if the Company determines,
within 30 days after your resignation, that discharge for cause was warranted.

will or applicable laws of descent and distribution, your rights and interests
under this Agreement and the Plan may not be assigned or transferred in whole or
in part either directly or by operation of law or otherwise, including without

bankruptcy, and no such rights or interests shall be subject to any of your
obligations or liabilities. Notwithstanding the foregoing, the Company consents

family trust or family partnership, provided that the Company shall not be
required to recognize any such transfer or assignment until such time as the
Company, the transferee and you execute a written assignment of the Option in
the form specified by the Company and upon the terms satisfactory to the
Company.
