reference and made a part of this Agreement. Capitalized terms not otherwise
defined herein shall have the same meanings as in the Plan; and

hereinafter set forth, all or any part of an aggregate of ____ Shares, subject
to adjustment as set forth in the Plan. The purchase price of the Shares subject
to the Option shall be $______ per Share (the "Option Price"). The Option is
intended to be a non-qualified stock option, and is not intended to be treated

hundred percent (100%) of the Shares initially covered by the Option on the
eighth anniversary of the Date of Grant.

            At any time, the portion of the Option which has become vested and
exercisable as described above (or pursuant to Section 2(c) below) is
hereinafter referred to as the "Vested Portion."

            (b) If the Participant's Employment with the Company is terminated

consideration and the Vested Portion of the Option shall remain exercisable for
the period set forth in Section 3(a).

            (c) Notwithstanding any other provisions of this Agreement to the
contrary, in the event of a Liquidity Event the Option shall, to the extent not

      Disability; provided, however, if Section 3(b)(ii) of this Agreement would

<PAGE>
                                                                               4

      notice shall specify the number of Shares for which the Option is being
      exercised and shall be accompanied by payment in full of the Option Price.
      The payment of the Option Price may be made at the election of the
      Participant (i) in cash or its equivalent (e.g., by check), (ii) to the
      extent permitted by the Committee, in Shares having a Fair Market Value
      equal to the aggregate Option Price for the Shares being purchased and
      satisfying such other requirements as may be imposed by the Committee;
      provided, that such Shares have been held by the Participant for no less
      than six months (or such other period as established from time to time by
      the Committee in order to avoid adverse accounting treatment applying
      generally accepted accounting principles), (iii) partly in cash and, to
      the extent permitted by the Committee, partly in such Shares or (iv) if

      exercise of the Option and to deliver promptly to the Company an amount

      the Shares being purchased. No Participant shall have any rights to
      dividends or other rights of a stockholder with respect to Shares subject
      to an Option until the Participant has given written notice of exercise of
      the Option, paid in full for such Shares and, if applicable, has satisfied
      any other conditions imposed by the Committee pursuant to the Plan.

            (ii) Notwithstanding any other provision of the Plan or this
      Agreement to the contrary, the Option may not be exercised prior to the
      completion of any registration or qualification of the Option or the
      Shares under applicable state and federal securities or other laws, or
      under any ruling or regulation of any governmental body or national
      securities exchange that the Committee shall in its sole discretion
      determine to be necessary or advisable.

            (iii) Upon the Company's determination that the Option has been
      validly exercised as to any of the Shares, the Company shall issue
      certificates in the Participant's name for such Shares. However, the
      Company shall not be liable to the Participant for damages relating to any
      delays in issuing the certificates to him, any loss of the certificates,
      or any mistakes or errors in the issuance of the certificates or in the
      certificates themselves.

            (iv) In the event of the Participant's death, the Vested Portion of
      the Option shall remain exercisable by the Participant's executor or
      administrator, or the person or persons to whom the Participant's rights
      under this Agreement shall pass by will or by the laws of descent and
      distribution as the case may be, to the extent set forth in Section 3(a).
      Any heir or legatee of the Participant shall take rights herein granted
      subject to the terms and conditions hereof.

            (v) As a condition to exercising the Option, the Participant shall
      become a party to the Stockholders Agreement.

            4. No Right to Continued Employment. The granting of the Option
evidenced hereby and this Agreement shall impose no obligation on the Company or
any Affiliate to continue the Employment of the Participant and shall not lessen
or affect the Company's or its Affiliate's right to terminate the Employment of
such Participant.

            5. Legend on Certificates. The certificates representing the Shares
purchased by exercise of the Option shall be subject to such stop transfer
orders and other restrictions as the

<PAGE>
                                                                               5

Committee may deem advisable under the Plan or the rules, regulations, and other
requirements of the Securities and Exchange Commission, any stock exchange upon
which such Shares are listed, and any applicable Federal or state laws, and the
Committee may cause a legend or legends to be put on any such certificates to
make appropriate reference to such restrictions.

            6. Transferability. The Option may not be assigned, alienated,
pledged, attached, sold or otherwise transferred or encumbered by the
Participant otherwise than by will or by the laws of descent and distribution,
and any such purported assignment, alienation, pledge, attachment, sale,
transfer or encumbrance shall be void and unenforceable against the Company or
any Affiliate; provided that the designation of a beneficiary shall not
constitute an assignment, alienation, pledge, attachment, sale, transfer or
encumbrance. No such permitted transfer of the Option to heirs or legatees of
the Participant shall be effective to bind the Company unless the Committee
shall have been furnished with written notice thereof and a copy of such
evidence as the Committee may deem necessary to establish the validity of the
transfer and the acceptance by the transferee or transferees of the terms and
conditions hereof. During the Participant's lifetime, the Option is exercisable
only by the Participant.

            7. Withholding. The Participant may be required to pay to the
Company or any Affiliate and the Company shall have the right and is hereby
authorized to withhold from any payment due or transfer made under the Option or
under the Plan or from any compensation or other amount owing to a Participant
the amount (in cash, Shares, other securities, other Awards or other property)
of any applicable withholding taxes in respect of the Option, its exercise or
any payment or transfer under or with respect to the Option or the Plan and to
take such other action as may be necessary in the opinion of the Committee to
satisfy all obligations for the payment of such withholding taxes.

            8. Securities Laws. Upon the acquisition of any Shares pursuant to
the exercise of the Option, the Participant will make or enter into such written
representations, warranties and agreements as the Committee may reasonably
request in order to comply with applicable securities laws or with this
Agreement.

            9. Notices. Any notice necessary under this Agreement shall be
addressed to the Company in care of its Secretary at the principal executive
office of the Company and to the Participant at the address appearing in the
personnel records of the Company for the Participant or to either party at such
other address as either party hereto may hereafter designate in writing to the
other. Any such notice shall be deemed effective upon receipt thereof by the
addressee.

            10. Choice of Law. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED
IN ACCORDANCE WITH THE LAWS OF THE STATE OF DELAWARE WITHOUT REGARD TO CONFLICTS
OF LAWS.

            11. Option Subject to Plan and Stockholders Agreement. By entering
into this Agreement the Participant agrees and acknowledges that the Participant
has received and read a copy of the Plan and the Stockholders Agreement. The
Option is subject to the Plan and the Stockholders Agreement. The terms and
provisions of the Plan and the Stockholders Agreement as it may be amended from
time to time are hereby incorporated herein by reference. In the event of a
conflict between any term or provision contained herein and a term or provision
of the Plan or the Stockholders Agreement, the applicable terms and provisions
of the Plan or the

            IN WITNESS WHEREOF, the parties hereto have executed this Agreement.
