          2.2 Continued Employment. The grant of a Cash Award to the Executive
pursuant to this Agreement does not give the Executive any right to be retained
in the employ of the Company; and the right and power of the Company to dismiss
or discharge the Executive, with or without cause, for any reason, is

sub-accounts, the first consisting of 25% of the Cash Award (the "First
Sub-Account"), the second consisting of 30% of the Cash Award (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
the Award or agree to issue a substitute award in place thereof, then any
unvested portion of the Cash Award shall vest in full and become payable in
accordance with Section 4.5 of this Agreement immediately prior to such merger,
reorganization, or consolidation

          3.3 Cessation of Credits. There shall be no further credits to a

shall have no interest in the Cash Award prior to vesting thereof or in excess
of the amount thereof vested. The Cash Award shall vest in three installments:

               4.1.1 The First Sub-Account shall vest on September 1, 2005;

               4.1.2 The Second Sub-Account shall vest on September 1, 2006; and

               4.1.3 The Third Sub-Account shall vest on September 1, 2007.

          4.2 Termination. Except as provided in Sections 4.3 and 4.4, if the
Executive's employment with the Company terminates for any reason, vesting shall
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
next Sub-Account due to vest, if any, shall immediately become payable in
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
vested prior to the date of death.

          4.5 Payment Amount. Within fifteen (15) business days after a
Sub-Account vests, the Company shall pay to the Executive a cash amount equal to
the balance of that Sub-Account.

          4.6 Payments only to the Executive. Payments pursuant to this
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 Agreement;
(b) construe the provisions of the Agreement; (c) correct any defect 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.

          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.

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

unenforceable provision as is possible and still be legal, valid and

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.

          8.8 Inurement. The rights and obligations under this Agreement shall
