for a third party other than the Corporation for a period of twelve (12) months
after the date of the termination of employment of the Employee under this

married on his Retirement Date (regardless of whether that is the same spouse to
whom he is married on his date of death), unless the Corporation is directed by
a court of competent jurisdiction to treat someone else as Employee's "spouse."

for purposes of this Section 5.2, "Spouse" shall mean the spouse to whom
Employee is married on his Early Retirement Date (regardless of whether that is
the same spouse to whom he is married on his date of death), unless the
Corporation is directed by a court of competent jurisdiction to treat someone

Payments shall commence as soon as administratively practicable following
Employee's Early Retirement Date, and subsequent payments shall be made as soon
as administrative practicable following each anniversary of Employee's Early
Retirement Date (payments shall not, however, commence earlier than the date

(a) Unless Employee makes the election described in Section 5.3(b) below,
Employee's Normal Retirement Benefit or Early Retirement Benefit, determined in

Benefit in the form of a lump sum as described in Section 5.3(a), Employee may
elect, in the manner prescribed by the Corporation, to receive payment of his

Any such election must be submitted to and accepted by the Corporation no later

death benefit payable under this Appendix A shall be as follows:

                                       9
<PAGE>

      (a) if Employee is married on his date of death, 50% of the lump sum that
      is Actuarially Equivalent to the Normal Retirement Benefit determined
      under Section 5.1(a) of this Appendix A, such lump sum benefit to be
      determined as if Employee Retired on his date of death after reaching
      Normal Retirement Age; or

      (b) if Employee is not married on his date of death, 50% of the lump sum
      that is Actuarially Equivalent to the Normal Retirement Benefit determined
      under Section 5.1(b) of this Appendix A, such lump sum benefit to be
      determined as if Employee Retired on his date of death after reaching
      Normal Retirement Age.

The death benefit shall be payable in a lump sum as soon as administratively
practicable following Employee's date of death.

6.2. Payee. This death benefit shall be payable to Employee's (a) surviving
spouse if Employee is married on his date of death, or (b) Beneficiary if
Employee is not married on his date of death. "Surviving spouse" for purposes of
this Section 6.2 means the spouse to whom Employee is married on his date of
death.

7. EFFECT OF A CHANGE IN CONTROL OF THE CORPORATION. Anything in this Appendix A
to the contrary notwithstanding, this Section 7 shall apply in the event of a
Change in Control. If, within three years after the date of a Change in Control
Employee's employment with the Corporation is involuntarily terminated by the
Corporation for any reason (other than Cause), or Employee voluntarily
terminates employment with the Corporation for Good Reason, and employee is not
otherwise eligible for Retirement, then Employee shall be deemed to have Retired
with a fully vested Normal Retirement Benefit on the date of such termination of
employment. Employee's Normal Retirement Benefit shall be determined as of such
deemed Retirement Date, and shall be payable in a lump sum, calculated pursuant
to Sections 5.1 and 5.3, as soon as administratively practicable following such
deemed Retirement Date.

Solely for purposes of this Section 7, "Good Reason" shall mean termination of
Employee's employment by Employee within 90 days following (i) a material
diminution in Employee's positions, duties and responsibilities from those
described in this Employment Agreement (ii) a reduction in Employee's Base
Salary (other than a reduction which is part of a general salary reduction
program affecting senior executives of the Corporation) (iii) a material
reduction in the aggregate value of the pension and welfare benefits provided to
Employee from those in effect prior to the Change in Control (other than a
reduction which is proportionate to the reductions applicable to other senior
executives pursuant to a cost-saving plan that includes all

                                       10
<PAGE>

senior executives), (iv) a material breach of any provision of this Employment
Agreement by the Corporation, (v) the Corporation's requiring Employee to be
based at a location that creates for Employee a one way commute in excess of 60
miles from his primary residence, except for required travel on the
Corporation's business to an extent substantially consistent with the business
travel obligations of Employee under this Employment Agreement. Notwithstanding
the foregoing, a termination shall not be treated as a termination for Good
Reason (i) if Employee shall have consented in writing to the occurrence of the
event giving rise to the claim of termination for Good Reason or (ii) unless
Employee shall have delivered a written notice to the Corporation within 30 days
of his having actual knowledge of the occurrence of one of such events stating
that he intends to terminate his employment for Good Reason and specifying the
factual basis for such termination, and such event, if capable of being cured,
shall not have been cured within 30 days of the receipt of such notice.

8. EFFECT OF TERMINATION OF EMPLOYMENT AND REHIRE. Upon Employee's termination
of employment with the Corporation the benefit payable under this Appendix A, if
any, shall be determined by the Corporation and such determination shall be
conclusive and binding (subject to Section 14). If Employee is subsequently
reemployed by the Corporation such reemployment, additional service, and
additional compensation shall not result in a re-determination of the benefits
due under this Appendix A. If, upon reemployment, Employee is receiving
installment payments pursuant to Section 5 those payments shall not be suspended
during any period of reemployment.

9. ADMINISTRATION.

9.1. Powers of the Corporation: The Board of Directors of the Corporation (the
"Board") shall have the sole authority to act on behalf of the Corporation under
this Appendix A (subject to Section 9.3), and shall have all the powers
necessary to administer the benefits under this Appendix A, including, without
limitation, the power to interpret the provisions of this Appendix A and to
establish rules and prescribe any forms required to administer benefits under
this Appendix A

9.2. Actions of the Board: All determinations, interpretations, rules, and
decisions of the Board shall be conclusive and binding upon all persons having
or claiming to have any interest or right under this Appendix A.

9.3. Delegation: The Board shall have the power to delegate specific duties and
responsibilities to officers or other employees of the Corporation or other
individuals or

                                       11
<PAGE>

entities. Any delegation by the Board may allow further delegations by the
individual or entity to whom the delegation is made. Any delegation may be
rescinded by the Board at any time. Each person or entity to whom a duty or
responsibility has been delegated shall be responsible for the exercise of such
duty or responsibility and shall not be responsible for any act or failure to
act of any other person or entity.

9.4. Reports and Records: The Board and those to whom the Board has delegated
duties under Section 9.3 shall keep records of all their proceedings and actions
and shall maintain books of account, records, and other data as shall be
necessary for the proper administration of this Appendix A and for compliance
with applicable law.

9.5. Costs: The costs of providing and administering the benefits under this
Appendix A shall be borne by the Corporation.

10. UNFUNDED BENEFITS; ESTABLISHMENT OF TRUST.

10.1. Unfunded Status. This Appendix A shall be unfunded for tax purposes and
for purposes of Title 1 of ERISA.

10.2. Establishment of Trust. The Corporation shall not be required to set aside
any funds to discharge its obligations hereunder, but may set aside such funds
to informally fund all or part of its obligations hereunder if it chooses to do
so, including without limitation the contribution of assets to a "rabbi trust"
(the Trust). Any setting aside of amounts, or acquisition of any insurance
policy or any other asset, by the Corporation with which to discharge its
obligations hereunder in trust or otherwise, shall not be deemed to create any
beneficial ownership interest in Employee, his surviving spouse, or Beneficiary,
and legal and equitable title to any funds so set aside shall remain in the
Corporation, and any recipient of benefits hereunder shall have no security or
other interest in such funds. The rights of Employee and his surviving spouse
and Beneficiary(ies) under this Appendix A shall be no greater than the rights
of a general unsecured creditor of the Corporation. Any and all funds so set
aside by the Corporation shall remain the general assets of the Corporation, and
subject to the claims of its general creditors, present and future.

10.3. Interrelationship of this Appendix A and the Trust. The provisions of this
Appendix A shall govern the rights of Employee to receive distributions pursuant
to the provisions of this Appendix A. The provisions of the Trust shall govern
the rights of the Corporation, Employee, and creditors of the Corporation to the
assets transferred to the Trust. The Corporation shall at all times remain
liable to carry out its obligations under this Appendix A.

                                       12
<PAGE>

10.4. Distributions from the Trust. The Corporation's obligations under this
Appendix A may be satisfied with Trust assets distributed pursuant to the terms
of the Trust, and any such distribution shall reduce the Corporation's
obligation under this Appendix A.

11. PAYMENT OF BENEFIT FOR DISABLED OR INCAPACITATED PERSON. If the Corporation
determines, in its discretion, that Employee or Employee's Beneficiary or
surviving spouse is under a legal disability or is incapacitated in any way so
as to be unable to manage his financial affairs, the Corporation shall make
payment to such person or to his legal representative or to a friend or relative
of such person as the Corporation considers advisable. Any payment under this
Section 11 shall be a complete discharge of any liability for the making of such
payment under this Appendix A. Nothing contained in this Section 11 however,
should be deemed to impose upon the Corporation any liability for paying a
benefit to any person who is under such a legal disability or is so
incapacitated unless it has received notice of such disability or incapacity
from a competent source.

12. NONASSIGNABILITY. Neither Employee nor any other person shall have any right
to commute, sell, assign, transfer, pledge, anticipate, mortgage or otherwise
encumber, transfer, hypothecate, alienate or convey in advance of actual
receipt, the amounts, if any, payable hereunder, or any part thereof, which are,
and all rights to which are expressly declared to be, unassignable and
non-transferable. No part of the amounts payable shall, prior to actual payment,
be subject to seizure, attachment, garnishment or sequestration for the payment
of any debts, judgments, alimony or separate maintenance owed by Employee or any
other person, be transferable by operation of law in the event of Employee's or
any other person's bankruptcy or insolvency or be transferable to a spouse as a
result of a property settlement or otherwise. The Corporation is authorized to
make any payments directed by court order.

13. CLAIM PROCEDURE.

13.1. Presentation of Claim. Employee, or the surviving spouse of Employee after
Employee's death, or Employee's Beneficiary (such Employee, surviving spouse, or
Beneficiary being referred to below as a "Claimant") may deliver to the
Corporation a written claim for a determination with respect to the amounts
distributable to such Claimant under this Appendix A. If such a claim relates to

initial ninety (90) day period. In no event shall such extension exceed a period
of ninety (90) days from the end of the initial period. The extension notice

notice from the Corporation that a claim has been denied, in whole or in part, a
Claimant (or the Claimant's duly authorized representative) may file with the

Claimant (or the Claimant's duly authorized representative):

      (a) may, upon request and free of charge, have reasonable access to, and

no event shall such extension exceed a period of sixty (60) days from the end of
the initial period. The extension notice shall indicate the special
circumstances requiring an extension of time and the date by which the
Corporation expects to render the benefit determination. In rendering its
decision, the Corporation shall take into account all comments, documents,

without regard to whether such information was submitted or considered in the
initial benefit determination. The decision must be written in a manner
calculated to be understood by the Claimant, and it must contain:

distributable pursuant to the terms of this Employment Agreement (including this

Code or any interest or penalties are incurred by the Employee with respect to
such excise tax (such excise tax, together with any such interest and penalties,
are hereinafter collectively referred to as the "Excise Tax"), then Employee
will be entitled to immediately receive an additional payment (a "Gross-Up
Payment") in an amount such that after payment by Employee of all taxes
(including any interest or penalties, other than interest and penalties imposed
by reason of Employee's failure to file timely a tax return or pay taxes shown
