</TABLE>

An installment shall not become exercisable on the otherwise applicable Vesting
Date if the Participant's termination of Full-Time Employment occurs on or
before such Vesting Date. Notwithstanding the foregoing provisions of this
paragraph 3, the SAR shall become vested and exercisable with respect to all of
the Covered Shares (to the extent it is not then otherwise exercisable) upon the
date of a Change in Control, if the Participant's termination of Full-Time
Employment does not occur on or before the Change in Control.

      4. Expiration. The SAR shall not be exercisable after the Company's close
of business on the last business day that occurs prior to the Expiration Date.
The "Expiration Date" shall be earliest to occur of:

            (a) the ten-year anniversary of the Grant Date;

            (b) if the Participant's Full-Time Employment terminates by reason
            of death, Disability or Retirement, the one-year anniversary of such
            termination;

            (c) if the Participant's Full-Time Employment is terminated by the
            Company for Cause (as herein defined) or if the Participant
            voluntarily resigns his employment with the Company for any reason
            other than Disability or Retirement, as of the date of such
            termination; or

            (d) if the Participant's Full-Time Employment terminates for reasons
            other than those specified above, the 90-day anniversary of such
            termination.

      The Committee may, in its discretion, provide for a longer
post-termination exercise period than the periods specified above. Any SAR or
portion thereof which is not vested as of the date of the Participant's
termination of Full-Time Employment shall terminate as of such date and be of no
further force and effect.

      5. Exercise of SAR. Subject to the terms of this Agreement and the Plan,
the SAR may be exercised in whole or in part by filing a written notice with the
Secretary of the Company at its corporate headquarters prior to the Company's
close of business on the last business day that occurs prior to the Expiration
Date. Upon the exercise of the SAR with respect to a share of Common Stock, the
Participant shall receive an amount from the Company which is equal to the

<PAGE>

excess of the Fair Market Value of a share of Common Stock on the date of
exercise over the Initial Value of one share of Common Stock. Such amount may be
paid to the Participant in cash, in shares of Common Stock (based on the Fair
Market Value of such shares on the date of exercise), or in a combination
thereof, as determined by the Committee in its discretion.

      6. Restrictions on Shares. No shares of Common Stock shall be transferred
pursuant to paragraph 5 (with or without consideration), sold, offered for sale,
assigned, pledged, hypothecated or otherwise disposed of (each a "Transfer") and
the Company shall not be required to register any such Transfer and the Company
may instruct its transfer agent not to register any such Transfer, unless and
until all of the following events shall have occurred:

            (a) such shares are Transferred pursuant to and in conformity with
            (i) (x) a registration statement filed with, and declared effective
            by, the Securities and Exchange Commission (the "SEC") pursuant to
            the Securities Act of 1933 (the "Act") or (y) an exemption from the
            registration requirements of the Act; and (ii) the securities laws
            of any state of the United States; and

            (b) Participant has, prior to the Transfer of such shares, and if
            requested by the Company, provided all relevant information to
            Company's counsel so that upon Company's request, the Company's
            counsel is able to, and actually prepares and delivers to the
            Company a written opinion that the proposed Transfer (i) is pursuant
            to a registration statement which has been filed with the SEC and is
            then effective, or (ii) is exempt from the registration requirements
            of the Act as then in effect, and the rules and regulations of the
            SEC thereunder. The Company shall bear all reasonable costs of
            preparing such opinion.

      Any attempted Transfer which is not in full compliance with this paragraph
6 shall be null and void ab initio, and of no force and effect.

      7. Transferability Restrictions. The SAR is not transferable other than as
designated by the Participant by will or by the laws of descent and distribution
(or on the Beneficiary Designation form attached as Exhibit A hereto), and
during the Participant's life, may be exercised only by the Participant.

      8. Investment Intent. Participant represents and agrees that if the
Participant exercised the SAR in whole or in part and if at any time of such
exercise the SAR, the Covered Shares and/or any shares of Common Stock that may
be issuable upon exercise of the SAR have not been registered under the Act, the
Participant will acquire such shares upon such exercise for the purpose of
investment and not with a view to the distribution of such shares in violation
of the Act, and that upon each exercise of the SAR he or she will furnish to the
Company a written statement to such effect and such other documentation as the
Company may request.

      9. Legend on Stock Certificates. Participant agrees that all certificates
representing the shares of Common Stock issuable upon exercise of the SAR (if
any) will be subject to such

<PAGE>

stock transfer orders and other restrictions (if any) as the Company may deem
advisable under the rules, regulations and other requirements of the SEC, any
stock exchange upon which the Common Stock is then listed and any applicable
federal or state securities laws, and the Company may cause a legend or legends
to be put on such certificates to make appropriate reference to such
restrictions.

      10. Definitions. For purposes of this Agreement, the terms used in this
Agreement shall be subject to the following:

            (a) Cause. "Cause" means (i) the failure or refusal of the
            Participant to perform the duties of his or her employment, (ii) the
            Participant's fraud or dishonesty against the Company or its
            Subsidiaries, or (iii) the Participant's willful or negligent acts
            or omissions which are materially harmful to the Company or its
            Subsidiaries, including, without limitation, the Participant's
            unauthorized disclosure of confidential information related to the
            business of the Company or any of its Subsidiaries. Whether the
            Participant's employment has been terminated for Cause shall be
            determined in good faith by the Committee, and such determination
            shall be final and binding on all persons.

            (b) Change in Control. The term "Change in Control" shall have the
            meaning set forth in the Plan.

            (c) Disability. "Disability" shall mean permanent disability as
            defined in the long-term disability policy of the Company or one of
            its Subsidiaries applicable to the Participant.

            (d) Full-Time Employment. "Full-Time Employment" shall mean regular
            employment as a common law employee of the Company or one of its
            Subsidiaries (as defined in the Plan) for at least 35 hours a week.

            (e) Retirement. "Retirement" of the Participant shall mean
            termination or resignation of Full-Time Employment on or after the
            Participant has attained age 65.

      11. Heirs and Successors. This Agreement shall be binding upon, and inure
to the benefit of, the Company and its successors and assigns, and upon any
person acquiring, whether by merger, consolidation, purchase of assets or
otherwise, all or substantially all of the Company's assets and businesses. If
any rights exercisable by the Participant or benefits deliverable to the
Participant under this Agreement have not been exercised or delivered,
respectively, at the time of the Participant's death, such rights shall be
exercisable by the Beneficiary, and such benefits shall be delivered to the
Beneficiary, in accordance with the provisions of this Agreement and the Plan.
The "Beneficiary" shall be the beneficiary or beneficiaries designated by the
Participant in writing on the Beneficiary Designation form attached as Exhibit A
hereto. If a deceased Participant fails to designate a Beneficiary, or if the

<PAGE>

Beneficiary does not survive the Participant, any rights that would have been
exercisable by the Participant and any benefits distributable to the Participant
shall be exercised by or distributed to the legal representative of the estate
of the Participant. If a deceased Participant designates a beneficiary and the
Beneficiary survives the Participant but dies before the Beneficiary's exercise
of all rights under this Agreement or before the complete distribution of
benefits to the Beneficiary under this Agreement, then any rights that would
have been exercisable by the Beneficiary shall be exercised by the legal
representative of the estate of the Beneficiary, and any benefits distributable
to the Beneficiary shall be distributed to the legal representative of the
estate of the Beneficiary.

      12. Administration. The authority to manage and control the operation and
administration of this Agreement shall be vested in the Committee, and the
Committee shall have all powers with respect to this Agreement as it has with
respect to the Plan. Any interpretation of the Agreement by the Committee and
any decision made by it with respect to the Agreement is final and binding on
all persons.

      13. Plan Governs. Notwithstanding anything in this Agreement to the
contrary, the terms of this Agreement shall be subject to the terms of the Plan,
a copy of which may be obtained by the Participant from the office of the
Secretary of the Company; and this Agreement is subject to all interpretations,
amendments, rules and regulations promulgated by the Committee from time to time
pursuant to the Plan.

      14. Not An Employment Contract. The SAR will not confer on the Participant
any right with respect to continuance of employment or other service with the
Company or any Subsidiary, nor will it interfere in any way with any right the
Company or any Subsidiary would otherwise have to terminate or modify the terms
of such Participant's employment or other service at any time.

      15. Notices. Any written notices provided for in this Agreement or the
Plan shall be in writing and shall be deemed sufficiently given if either hand
delivered of if sent by fax or overnight courier, or by postage paid first class
mail. Notices sent by mail shall be deemed received three business days after
mailing but in no event later than the date of actual receipt. Notices shall be
directed, if to the Participant, at the Participant's address indicated by the
Company's records, or if to the Company, at the Company's principal executive
office.

      16. Fractional Shares. In lieu of issuing a fraction of a share upon any
exercise of the SAR, the Company will be entitled to pay to the Participant an
amount equal to the fair market value of such fractional share.

      17. No Rights As Stockholder. The Participant shall not have any rights of
a stockholder with respect to the shares distributable with respect to the SAR,
until a stock certificate has been duly issued following exercise of the SAR as
provided herein.

<PAGE>

      18. Participant Representation. The Participant represents that this
Agreement has been duly executed and delivered by the Participant and
constitutes a legal, valid and binding agreement of the Participant, enforceable
against the Participant in accordance with its terms.

      19. Tax Withholding. The Company or any related corporation shall have the
right to retain and withhold from any payment of cash or Common Stock under this
Agreement or the Plan the amount of taxes required by any government to be
withheld or otherwise deducted and paid with respect to such payment. At its
discretion, the Company may require the Participant receiving shares of Common
Stock to reimburse the Company for any such taxes required to be withheld by the
Company and withhold any distribution in whole or in part until the Company is
so reimbursed. In lieu thereof, the Company shall have the right to withhold
from any cash amounts due or to become due from the Company to the Participant
an amount equal to such taxes and any interest and penalties payable by the
Company with respect to such taxes, or retain and withhold that number of shares
having a fair market value equal to the minimum statutory total tax which could
be imposed on the transaction to reimburse the Company for any such taxes and
cancel (in whole or in part) any such shares so withheld.

      20. No Restriction on Right of Company to Effect Corporate Changes.
Neither the Plan nor this Agreement shall affect in any way the right or power
of the Company or its stockholders to make or authorize any or all adjustments,
recapitalization, reorganizations or other changes in the Company's capital
structure or its business, or any merger or consolidation of the Company, or any
issue of stock or of options, warrants or rights to purchase stock or of bonds,
debentures, preferred or prior preference stocks whose rights are superior to or
affect the Common Stock or the rights thereof or which are convertible into or
exchangeable for Common Stock, or the dissolution or liquidation of the Company,
or any sale or transfer of all or any part of its assets or business, or any
other corporate act proceeding, whether of a similar character or otherwise.

      21. Amendment. This Agreement may be amended by written agreement of the
Participant and the Company, without the consent of any other person.

      22. Waiver. The waiver by either party of compliance with any provision of
this Agreement by the other party shall not operate or be construed as a waiver
of any other provision of this Agreement, or of any subsequent breach by such
party of a provision of this Agreement.
