Sub-Account"), the second consisting of 30% of the Cash Award

                                       2



(the "Second Sub-Account"), and the third consisting of 45% of the Cash Award
(the "Third Sub-Account"). The Account shall not earn interest.

        3.2 Corporate Changes. In the event of a liquidation of the Company, or
a merger, reorganization, or consolidation of the Company with any other
corporation in which the Company is not the surviving corporation or the Company
becomes a wholly-owned subsidiary of another corporation, if the surviving
corporation in any such merger, reorganization, or consolidation does not assume

immediately cease upon the date of termination and no vesting credit shall be
given for partial years, regardless of the reason for the termination.

        4.3 Termination in Connection With a Change of Control. Notwithstanding
Sections 4.1 and 4.2, if Executive's employment with the Company terminates as
described in Section 5.01 of the Change of Control Severance Plan, then any
unvested portion of the Cash Award shall vest in full and become payable in
accordance with Section 4.5 of this Agreement.

        4.4 Termination due to Death. Notwithstanding Sections 4.1 and 4.2, if
the Executive's employment with the Company terminates due to death, then the

accordance with Section 4.5 of this Agreement, and vesting shall immediately
cease upon the date of death for any other Sub-Account that was not already

Sub-Account vests, the Company shall pay to the Executive a cash amount equal to
the balance of that Sub-Account.

Agreement shall be made only to the Executive or his heirs.

                  4.7 Deferral. Subject to the terms of the Deferred
Compensation Plan, the Executive may elect at any time prior to December 31 of
the year prior to the year of vesting and payment of any Sub-Account, to defer
receipt of any or all payments due under this Agreement with respect to such
Sub-Account. Such election shall be made, and any such deferral shall be
effected and administered, in accordance with the Deferred Compensation Plan.
Notwithstanding anything to the contrary in the Agreement, the Administrator
reserves the right to modify or eliminate this Section 4.7, and the right of the
Executive to defer payment hereunder, in whole or in part.

         5. ADMINISTRATION OF THE AGREEMENT.

                  5.1 Administrator. This Agreement shall be administered by the
Administrator, which shall have complete discretion and authority to interpret
and construe the Agreement, decide all questions of benefits (including
underlying factual determinations), and adjudicate all claims and disputes. The
Committee may delegate any of its responsibilities with respect to the Agreement
to the Company's Chief Executive Officer. The determinations of the
Administrator on the matters referred to in this Agreement shall be final and
binding on all interested parties.

                  5.2 Administrative Rules. The Administrator may (a) adopt,
amend, and rescind rules and regulations relating to the administration of this

or supply any omission or reconcile any inconsistency in the Agreement in the
manner and to the extent it, in its sole discretion, shall deem expedient to
carry the Agreement into effect; and (d) make all determinations necessary or
advisable for administering the Agreement.

                  5.3 Amendment, Modification, Suspension and Termination of
Cash Award. The Administrator may from time to time in its discretion amend,
modify, suspend, or terminate, in whole or in part, any or all provisions of the
Agreement, including but not limited to providing for shorter or longer vesting
periods. Notwithstanding the foregoing, the Cash Award shall not be amended,
modified, suspended or terminated in such a manner as to impair any rights of
the Executive under the Cash Award without the consent of the Executive.

         6. TAXES.

                  6.1 Withholding. The amounts payable to the Executive under
this Agreement shall be reduced by any amount that the Company is required to
withhold with respect to such payments under the then-applicable provisions of
the Internal Revenue Code of 1986, as amended, and state and local law.

                                       4



                  6.2 Executive Taxes. The Company is not responsible for, and
makes no representation or warranty whatsoever in connection with, the tax
treatment hereunder, and the Executive should consult Executive's own tax
advisor.

         7. ASSIGNMENT.

         No right or interest to or in this Agreement, or any payment or benefit
to the Executive under this Agreement shall be assignable by the Executive
except by will or the laws of descent and distribution. No right, benefit or
interest of the Executive hereunder shall be subject to anticipation,
alienation, sale, assignment, encumbrance, charge, pledge, hypothecation or set
off in respect of any claim, debt or obligation, or to execution, attachment,
levy or similar process or assignment by operation of law. Any attempt,
voluntarily or involuntarily, to effect any action specified in the immediately
preceding sentences shall, to the full extent permitted by law, be null, void
and of no effect; provided, however, that this provision shall not preclude the
Executive from designating one or more beneficiaries to receive any amount that
may be payable to the Executive under this Agreement after Executive's death and
shall not preclude the legal representatives of the Executive's estate from
assigning any right hereunder to the person or persons entitled thereto under
Executive's will, or, in the case of intestacy, to the person or persons
entitled thereto under the laws of intestacy applicable to the Executive's
estate.

         8. GENERAL.

                  8.1 Laws Governing. The substantive laws of the State of

of this Agreement, unless otherwise specified herein.

                  8.2 Good Faith Determinations. No member of the Committee or
the Board shall be liable, with respect to this Agreement, for any act, whether
of commission or omission, taken by any other member or by any officer, agent,
or employee of the Company, nor, excepting circumstances involving his or her
own bad faith, for anything done or omitted to be done by himself or herself.
The Company shall indemnify and hold harmless each member of the Committee and
Board from and against any liability or expense hereunder, except in the case of
such member's own bad faith.

                  8.3 Effect of Headings. Section headings contained in the
Agreement are for convenience only and shall not affect the construction or
interpretation of the Agreement.

                  8.4 Invalid Provisions. If any provision of this Agreement is
held to be illegal, invalid or unenforceable under present or future laws
effective during the term of the Agreement, such provision shall be fully
severable; the Agreement shall be construed and enforced as if such illegal,
invalid or unenforceable provision had never been a part of the Agreement; and
the remaining provisions of the Agreement shall remain in full force and effect
and shall not be affected by the illegal, invalid or unenforceable provision or
severance from the Agreement. Furthermore, in lieu of such illegal, invalid or
unenforceable provision there shall be added automatically as part of the
Agreement a provision as similar in terms to such illegal, invalid or
unenforceable provision as is possible and still be legal, valid and
enforceable.

improper venue or forum non conveniens to the conduct of any such action or
proceeding in any such court.

                  8.7 Waiver. No waiver of any term or condition hereof shall be
binding unless it is in writing and signed by the Company and the Executive. The
waiver by any party of a breach of any provision of this Agreement shall not
operate or be construed as a waiver of any subsequent breach by any party.

shall inure to the benefit of, and shall be binding upon the Company, its
successors and assigns, and the Executive and the Executive's beneficiaries and
