                                       5
<PAGE>

      The foregoing notwithstanding, Employee's deferrals of Compensation under
      this Appendix A shall be suspended (a) for any period of time required by
      Treasury Regulation 1.401(k)-1(d)(2)(iv)(B)(4) in the event Employee
      receives a hardship distribution from a section 401(k) plan maintained by
      the Corporation, and (b) for any period of time during which Employee is
      Disabled.

3.2   Timing of Deferred Compensation Agreement.

      (a)   Deferrals of Base Salary. Employee may enter into a Deferred
      Compensation Agreement with respect to his Base Salary prior to January 1
      of each calendar year. The Deferred Compensation Agreement shall apply to
      Base Salary earned in the immediately following calendar year, and shall
      be irrevocable for such calendar year, except as provided in Section 3.1
      of this Appendix A.

      In the year the Employment Agreement is executed, Employee may enter into
      a Deferred Compensation Agreement within 30 days of the effective date of
      the Employment Agreement. Such Deferred Compensation Agreement shall apply
      to Base Salary earned after the Deferred Compensation Agreement is
      executed, and shall be irrevocable for the balance of the calendar year.

      (b)   Deferrals of Bonus. Employee may enter into a Deferred Compensation
      Agreement with respect to Bonus no later than September 30 of the calendar
      year prior to the calendar year in which the Bonus would otherwise be
      paid. The Corporation may, in its discretion, instead require that
      Employee enter into a Deferred Compensation Agreement with respect to
      Bonus prior to the beginning of the period during which such Bonus will be
      earned. Such deferral elections shall be irrevocable, except as provided
      in Section 3.1. Subsequent deferrals of Bonus shall be made only pursuant
      to a new Deferred Compensation Agreement.

3.3   Amount of Deferrals.

                                       6
<PAGE>

            her Base Salary, in increments of 1%.

      (b)   From Bonus. Employee may elect to defer up to 100% of his Bonus, in
            increments of 5%.

      A Deferral Election may be reduced by the Corporation if the Corporation
      determines, in its sole discretion, that such action is necessary to meet
      Federal or State tax withholding obligations.

3.4   Deferral Period.

      (a)   General. At the time Employee defers Compensation pursuant to a
      Deferred Compensation Agreement for a calendar year, he may specify an
      In-Service Distribution Date applicable to all or a portion of the
      deferrals for such calendar year, and earnings thereon. Any deferrals of
      Compensation not deferred to an In-Service Distribution Date shall be
      deemed deferred to Retirement.

      (b)   Retirement Subaccount. The Corporation shall establish a Retirement
      Subaccount on Employee's behalf representing Compensation Employee has
      deferred to Retirement, and earnings thereon. Payments from Employee's
      Retirement Subaccount shall be made at such time and in such manner as
      provided in Section 6.3.

      (c)   Deferrals to an In-Service Distribution Date. Deferrals to an
      In-Service Distribution Date shall be subject to the following
      requirements:

               (i)   In-Service Distribution Date. The In-Service Distribution
               Date must be a date at least three full calendar years after the
               date of such Deferred Compensation Agreement.

               (ii)  In-Service Distribution Subaccount. The Corporation shall
               establish an In-Service Distribution Subaccount on Employee's
               behalf to which Employee's deferrals relating to a particular
               In-Service Distribution Date,

                                       7
<PAGE>

            and earnings thereon, shall be credited.

            (iii) Limits. There are no limits on the number of In-Service
            Distribution Subaccounts Employee may establish.

            (iv)  Payments. Payments from In-Service Distribution Subaccounts
            shall be made at such time and in such manner as provided in Section
            6.2.

      (d)   Postponing In-Service Distributions. Employee may elect to postpone
      payment of an In-Service Distribution Subaccount, and instead have such
      amount paid out as soon as administratively practicable after an allowable
      alternative In-Service Distribution Date, by submitting a new In-Service
      Distribution Election Form to the Corporation, subject to the following:

            (i)   Such Election Form must be submitted to and accepted by the
            Corporation in its sole discretion no later than the 13th month
            prior to Employee's previously elected In-Service Distribution Date;
            and

            (ii)  The new In-Service Distribution Date selected by Employee must
            be the first day of any calendar year that is at least three full
            calendar years after the end of the calendar year in which the
            previously elected In Service Distribution would otherwise have been
            paid to Employee.

3.5   Vesting of Retirement and In-Service Distribution Subaccounts.

      Subject to Section 11.2, Employee's Retirement Subaccount and In-Service
      Distribution Subaccount(s) shall be fully vested and nonforfeitable.

4. COMPANY CONTRIBUTIONS.

4.1   Required Company Contribution. The Corporation shall make an annual
      hypothetical contribution on Employee's behalf equal to 15% of Employee's
      Compensation. Such hypothetical contribution shall commence with the

                                       8
<PAGE>

      calendar year the Employment Agreement is executed by the Corporation and
      Employee, and shall continue each calendar year up to and including the
      year in which Employee severs employment with the Corporation for any
      reason other than Termination of Employment. Solely for purposes of this
      Section 4.1, "Compensation" in the calendar year Employee severs
      employment with the Corporation shall mean only Base Salary and Bonus
      actually paid to Employee in such calendar year.

4.2   Discretionary Company Contribution.

      The Corporation may, in its absolute discretion, make an additional
      hypothetical contribution on Employee's behalf with respect to any
      calendar year. The fact that the Corporation makes a discretionary
      contribution with respect to a particular calendar year shall not obligate
      the Corporation to make a discretionary contribution with respect to any
      other calendar year.

4.3   Company Contribution Subaccount.

      The Corporation shall establish a Company Contribution Subaccount on
      behalf of Employee to which hypothetical required company contributions
      and discretionary company contributions, and earnings thereon, shall be
      allocated.

4.4   Vesting of Company Contribution Subaccount.

      Subject to Sections 4.5, 4.6, 4.7, and Section 11.2 of this Appendix A,
      Employee's Company Contribution Subaccount shall vest upon the earlier of
      (a) or (b), where (a) is the following vesting schedule:

<TABLE>
<CAPTION>

    By the Corporation          Vested Percentage
<S>                             <C>
          65                            100%
          64                             90%

</TABLE>

and (b) is the date of Employee's deemed Retirement under Section 2.14(b).

                                       9
<PAGE>

      Except as provided in Section 8 of this Appendix A, Employee's Company
      Contribution Subaccount shall be forfeited upon Employee's Termination of
      Employment.

4.5.  Compliance with Noncompete, Nondisclosure, and Nonsoliciation Agreements.
      Employee's Company Contribution Account shall be forfeited in the event
      the Corporation determines that Employee has failed to comply with the
      terms of any noncompetition, nondisclosure, or nonsolicitation provision
      contained in the Employment Agreement, or in any other agreement between
      Employee and the Corporation. If Employee violates the terms of any such
      provision, and installment payments have commenced to Employee, the
      Corporation shall make a reasonable determination, in its sole discretion,
      of the portion of such installment payments allocable Employee's Company
      Contribution Account, and such installment payments shall be permanently
      reduced by the amount so determined.

4.6.  Notice of Intent to Retire. Benefits payable under Section 6.1(a) of this
      Appendix A attributable to Employee's Company Contribution Subaccount are
      specifically conditioned upon Employee providing to the Corporation
      written notice of Employee's intent to Retire at least six months prior to
      Employee's Retirement date. In the event Employee fails to satisfy the
      notice requirements of this Section 4.6 Employee's Company Contribution
      Subaccount shall be forfeited, and no amount attributable to such
      Subaccount shall be payable under this Appendix A. The foregoing
      notwithstanding, this section 4.6 shall not apply to benefits payable
      under Section 6.1(a) as a result of Employee's deemed Retirement under
      Section 2.14(b) of this Appendix A. The Corporation, in its sole and
      absolute discretion, may elect to waive the notice requirement of this
      Section 4.6

4.7.  Release. Benefits payable under Section 6.1(a) of this Appendix A
      attributable to Employee's Company Contribution Account are specifically
      conditioned upon and provided in exchange for Employee signing a
      separation agreement that releases the Corporation from any liabilities
      that may have arisen as a result of

                                       10
<PAGE>

      Employee's employment and/or termination of employment with the
      Corporation. In the event Employee terminates employment with the
      Corporation for any reason other than death without satisfying the
      requirements of this Section 4.7 Employee's Company Contribution Account
      shall be forfeited, and no amount attributable to such Subaccount shall be
      payable under this Appendix A.

4.8   Payment of Company Contribution Subaccount. Employee's vested Company
      Contribution Subaccount shall be paid at such time and in such manner as
      provided in Section 6.

5. EMPLOYEE'S DEFERRED COMPENSATION ACCOUNT.

5.1   Establishment of Deferred Compensation Accounts and Subaccounts.
      The Corporation shall establish and maintain a hypothetical account for
      Employee called the Deferred Compensation Account. Such Account shall be
      segregated from the other accounts on the books and records of the
      Corporation as an unfunded and unsecured liability of the Corporation to
      Employee. Subaccounts (including Employee's Company Contribution
      Subaccount, In-Service Distribution Subaccount(s), and Retirement
      Subaccount) shall be maintained as determined necessary by the
      Corporation. Accounts and subaccounts are maintained solely as a device
      for the measurement and determination of the amounts to be paid to
      Employee or his Beneficiary pursuant to this Appendix A. Any reference to
      "contributions to" or "payments from" Employee's Accounts or subaccounts,
      or similar phrases, are for convenience only.

5.2   Timing of Contributions to and Distributions From Employee's Deferred
      Compensation Account. The Corporation shall credit to Employee's Deferred
      Compensation Account an amount equal to the percentage of Employee's Base
      Salary and Bonus which he has elected to defer in accordance with Section
      3.3, as of the last day of the calendar month in which Employee would have
      received

                                       11
<PAGE>

      such amount if not for Employee's deferral election.

      The Corporation shall credit to Employee's Deferred Compensation Account
      an amount equal to the Company Contribution(s) to which he is entitled
      under Sections 4.1 and 4.2 as soon as administratively practicable after
      the end of each calendar year.

      Any distribution with respect to Employee's Deferred Compensation Account
      shall be charged to such Account as of the date the distribution is made
      by the Corporation or from the Trust established in accordance with this
      Appendix A.

5.3   Selection of Investment Vehicle.

      Employee shall specify, in the manner prescribed by the Corporation, the
      allocation of his Account among investment indices available under this
      Appendix A. An individual's selection of an investment index will have no
      bearing on the actual investment or segregation of Corporation assets, but
      will be used as the basis for making adjustments to such individual's
      Account as described in Section Article 5.4 below. Employee can change his
      or her investment index or indices at such time, and in such manner, as
      determined by the Corporation. The Corporation may change the investment
      indices available under this Appendix A at any time in its absolute
      discretion.

5.4   Adjustment of Deferred Compensation Account.

      As of the last day of each calendar month, or more frequently as
      determined in the sole discretion of the Corporation, Employee's Deferred
      Compensation Account shall be credited with hypothetical net income, gain
      and loss, including hypothetical net unrealized gain and loss, based on
      the hypothetical investment directions made by the Participant in
      accordance with Section 5.3 of this Appendix A. Such earnings will
      continue to accrue during any period in which installments are paid
      pursuant to Section 6.1(a).

6.    BENEFIT PAYMENTS.

                                       12
<PAGE>

6.1   Payment of Company Contribution Subaccount.

      (a) Payment upon Retirement. Payment of the vested portion of Employee's
      Company Contribution Subaccount shall be made, or shall commence, as soon
      as administratively practicable following Employee's Retirement, and the
      nonvested portion shall be forfeited. Payment shall be made in a lump sum
      unless Employee elects to receive payment of his Account under an Annual
      Installment Method, as defined below. Such election shall be made on a
      form prescribed by the Corporation, which must be received and accepted by
      the Corporation no later than the 13th month prior to Employee's
      Retirement date.

      "Annual Installment Method" shall mean annual installment payments over
      10, 15, or 20 years as elected by Employee, calculated as follows: (i) for
      the first annual installment, Employee's Company Contribution Subaccount
      balance shall be calculated as of the close of business on the last day of
      the calendar month immediately preceding the calendar month containing
      Employee's Retirement date, and (ii) for remaining annual installments,
      Employee's subaccount balance shall be calculated on the last day of the
      calendar month immediately preceding the calendar month containing the
      anniversary of Employee's Retirement Date. Each annual installment shall
      be calculated by multiplying this balance by a fraction, the numerator of
      which is one and the denominator of which is the remaining number of
      annual payments due to Employee. By way of example, if Employee elects a
      ten (10) year Annual Installment Method, the first payment shall be 1/10
      of Employee's Company Contribution Subaccount balance, calculated as
      described in this definition. The following year, the payment shall be 1/9
      of the Account balance, calculated as described in this definition, and so
      on.

      (b) Payment Upon Death. Death benefits shall be payable under this
      Appendix A only as follows:

            (i)   In the event Employee dies while employed by the Corporation,
            Employee's Company Contribution Subaccount shall be payable to
            Employee's Beneficiary in a lump sum as soon as administratively

                                       13
<PAGE>

            practicable following Employee's death.

            (ii)  In the event Employee dies after Retirement while receiving
            installment payments, installment payments shall cease and
            Employee's remaining vested Company Contribution Subaccount balance
            shall be paid to Employee's Beneficiary in a lump sum as soon as
            administratively practicable following Employee's death. In the
            event Employee dies after Retirement, but before any payment
            required under Section 6(a) has been paid to Employee, Employee's
            vested Company Contribution Subaccount balance shall be paid to
            Employee's Beneficiary in a lump sum as soon as administratively
            practicable following Employee's death.

6.2 Payment of In-Service Distribution Subaccount.

      Employee's In-Service Distribution Subaccount(s) shall be paid in a single
      lump sum. Payment shall be made as soon as administratively practicable
      after the earlier of (a) the Participant's In-Service Distribution Date,
      or (b) the date Employee terminates employment for any reason.

6.3   Payment of Retirement Subaccount.

      (a) Payment upon Retirement. In the event of Retirement Employee's
      Retirement Subaccount shall be paid at the same time, and in the same
      form, as Employee's Company Contribution Subaccount.

      (b) Payment upon Termination of Employment. In the event of Termination of
      Employment, Employee's Retirement Subaccount shall be paid in a single
      lump sum. Payments shall be made as soon as administratively practicable
      after the Participant's Termination of Employment.

6.4   Distribution of Taxable Amounts.

      Notwithstanding the foregoing provisions of this Section 6, in the event
      Employee or Employee's Beneficiary is determined to be subject to federal

                                       14
<PAGE>

      income tax on any amount credited to the Employee's Deferred Compensation
      Account prior to the time payment is otherwise due hereunder, the entire
      amount determined to be so taxable shall be paid from Employee's Account
      by the Corporation to Employee or Employee's Beneficiary. Any amount to
      the credit of Employee's Deferred Compensation Account shall be determined
      to be subject to federal income tax upon the earlier of:

      (a) determination by the Internal Revenue Service addressed to Employee or
      Beneficiary which is not appealed; or

      (b) a final determination by the United States Tax Court or any other
      Federal Court affirming any such determination by the Internal Revenue
      Service that amounts credited to Employee's Account are subject to federal
      income tax.

6.5   Timing of Distributions- Federal Law.

      Notwithstanding the foregoing provisions of this Section 6, benefit
      payments shall not be made or commence to Employee prior to the date
      otherwise permitted by federal law, as determined in the sole discretion
      of the Corporation.

7. LIMITATIONS ON LIABILITY.

   Notwithstanding any of the preceding provisions of this Appendix A, neither
   the Corporation, nor any individual acting as employee or agent of the
   Corporation, shall be liable to Employee or other person for any claim, loss,
   liability or expense incurred in connection with this Appendix A.

   The Corporation does not in any way guarantee Employee's Deferred
   Compensation Account against loss or depreciation, whether caused by poor
   investment performance, insolvency of a deemed investment or by any other
   event or occurrence. In no event shall the employees, officers, directors, or
   stockholders of the Corporation be liable to any individual or entity on
   account of any claim arising by reason of the provisions of this Appendix A
   or any instrument or instruments implementing its provisions, or for the
   failure of any Employee, Beneficiary or other individual or entity to be
   entitled to any particular tax consequences with

                                       15
<PAGE>

      respect to this Appendix A, or any credit or payment hereunder.

      Nothing contained in this Appendix A shall constitute a guarantee by the
      Corporation or any other person or entity that the assets of the
      Corporation will be sufficient to pay any benefits hereunder.

      Any payment made in good faith in accordance with provisions of this
      Appendix A shall be a complete discharge of any liability for the making
      of such payment under the provisions of this Appendix A.

8. EFFECT OF A CHANGE IN CONTROL OF THE CORPORATION. Anything in this Appendix A
to the contrary notwithstanding, this Section 8 shall apply in the event of a
Change in Control. If, within three years after the date of a Change in Control
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 benefit on the date of such
termination of employment. Employee's Deferred Compensation Account balance,
determined as of the valuation date immediately preceding Employee's termination
of employment, shall be payable in a lump sum as soon as administratively
practicable following such deemed Retirement Date.

Solely for purposes of this Section 8, "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) if Employee is a member of the Board
of Directors, the removal of Employee from, or the failure to re-elect Employee
as a member of, the Board, (iii) 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) (iv) 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 senior executives), (v) a material
breach of any provision of this Employment Agreement by the Corporation, (vi)
the

                                       16
<PAGE>

Corporation's requiring Employee to be based at a location that creates a
one-way commute for Employee 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.

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

10.3. 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 entities. Any delegation by the Board may allow

      duties under Section 10.3 shall keep records of all their proceedings and

      for compliance with applicable law.

11. UNFUNDED BENEFITS; ESTABLISHMENT OF TRUST.

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

11.2. 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

                                       18
<PAGE>

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.

11.3. Interrelationship of this Appendix A and the Trust. The provisions of this

assets transferred to the Trust. The Corporation shall at all times remain
liable to carry out its obligations under this Appendix A.

11.4 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.

12. PAYMENT OF BENEFIT FOR DISABLED OR INCAPACITATED PERSON.

    If the Corporation determines, in its discretion, that Employee or
    Employee's Beneficiary 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 12 shall
    be a complete discharge of any liability for the making of such payment
    under this Appendix A. Nothing contained in this Section 12 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.

                                       19

13. 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.

      the claim. The Claimant (or the Claimant's duly authorized
      representative):

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

                                       21

      may grant.

14.4. Decision on Review. The Corporation shall render its decision on review
      promptly, and no later than sixty (60) days after the Corporation receives
      the Claimant's written request for a review of the denial of the claim. If
      the Corporation determines that special circumstances require an extension
      of time for processing the claim, written notice of the extension shall be
      furnished to the Claimant prior to the termination of the initial sixty
      (60) day period. In no event shall such extension exceed a period of sixty
      (60) days from the end of the initial period. The extension notice shall

      commence any legal action with respect to any claim for benefits under
      this Appendix A.

15. TAX WITHHOLDING AND REPORTING.

    (a) General: The Corporation shall have the right to deduct any required
    withholding taxes from any payment made under this Appendix A. Except as
    provided in Section 15(b), the Corporation shall not be obligated to pay or
    reimburse Employee, or his surviving spouse or Beneficiary, for any income
    or other taxes or penalties that may be imposed on such person by the
    Internal Revenue Service or any state or other taxing authority as a result
    of benefits paid under this Appendix A.

    (b) Excise Tax Payment. In the event that any payment or benefit (within the
    meaning of Section 280G(b)(2) of the Internal Revenue Code of 1986, as
    amended (the "Code")), to Employee or for his benefit paid or payable or
    distributed or distributable pursuant to the terms of this Employment
    Agreement (including this Appendix A) or otherwise in connection with, or
    arising out of, his employment with the Corporation or a Change in Control
    of the Corporation (a "Payment" or "Payments"), would be subject to the
    excise tax imposed by Section 4999 of the 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 due on
    his return, imposed with respect to such taxes and the Excise Tax),
    including any Excise Tax imposed upon the Gross-Up Payment, Employee retains
    an amount of the Gross-Up Payment equal to the Excise Tax imposed upon the
    Payments.

      Federal or State tax withholding obligations.

3.4   Deferral Period.

      (a)   General. At the time Employee defers Compensation pursuant to a
      Deferred Compensation Agreement for a calendar year, he may specify an
      In-Service Distribution Date applicable to all or a portion of the
      deferrals for such calendar year, and earnings thereon. Any deferrals of

            Distribution Date,

                                        7

            and earnings thereon, shall be credited.

            (iii) Limits. There are no limits on the number of In-Service
            Distribution Subaccounts Employee may establish.

            (iv) Payments. Payments from In-Service Distribution Subaccounts
            shall be made at such time and in such manner as provided in Section
            6.2.

      (d)   Postponing In-Service Distributions. Employee may elect to postpone
      payment of an In-Service Distribution Subaccount, and instead have such

            be the first day of any calendar year that is at least three full
            calendar years after the end of the calendar year in which the
            previously elected In Service Distribution would otherwise have been
            paid to Employee.

3.5   Vesting of Retirement and In-Service Distribution Subaccounts.

      Subject to Section 11.2, Employee's Retirement Subaccount and In-Service
      Distribution Subaccount(s) shall be fully vested and nonforfeitable.

      the Corporation to make a discretionary contribution with respect to any
      other calendar year.

4.3   Company Contribution Subaccount.

      The Corporation shall establish a Company Contribution Subaccount on
      behalf of Employee to which hypothetical required company contributions

      terms of any noncompetition, nondisclosure, or nonsolicitation provision
      contained in the Employment Agreement, or in any other agreement between
      Employee and the Corporation. If Employee violates the terms of any such
      provision, and installment payments have commenced to Employee, the
      Corporation shall make a reasonable determination, in its sole discretion,
      of the portion of such installment payments allocable Employee's Company
      Contribution Account, and such installment payments shall be permanently
      reduced by the amount so determined.

4.6.  Notice of Intent to Retire. Benefits payable under Section 6.1(a) of this
      Appendix A attributable to Employee's Company Contribution Subaccount are
      specifically conditioned upon Employee providing to the Corporation
      written notice of Employee's intent to Retire at least six months prior to
      Employee's Retirement date. In the event Employee fails to satisfy the
      notice requirements of this Section 4.6 Employee's Company Contribution
      Subaccount shall be forfeited, and no amount attributable to such
      Subaccount shall be payable under this Appendix A. The foregoing
      notwithstanding, this section 4.6 shall not apply to benefits payable
      under Section 6.1(a) as a result of Employee's deemed Retirement under
      Section 2.14(b) of this Appendix A. The Corporation, in its sole and
      absolute discretion, may elect to waive the notice requirement of this
      Section 4.6

4.7.  Release. Benefits payable under Section 6.1(a) of this Appendix A
      attributable to Employee's Company Contribution Account are specifically
      conditioned upon and provided in exchange for Employee signing a
      separation agreement that releases the Corporation from any liabilities
      that may have arisen as a result of

                                       10
<PAGE>

      Employee's employment and/or termination of employment with the
      Corporation. In the event Employee terminates employment with the
      Corporation for any reason other than death without satisfying the
      requirements of this Section 4.7 Employee's Company Contribution Account
      shall be forfeited, and no amount attributable to such Subaccount shall be
      payable under this Appendix A.

4.8   Payment of Company Contribution Subaccount. Employee's vested Company
      Contribution Subaccount shall be paid at such time and in such manner as
      provided in Section 6.

5.    EMPLOYEE'S DEFERRED COMPENSATION ACCOUNT.

5.1   Establishment of Deferred Compensation Accounts and Subaccounts.

      The Corporation shall establish and maintain a hypothetical account for
      Employee called the Deferred Compensation Account. Such Account shall be
      segregated from the other accounts on the books and records of the
      Corporation as an unfunded and unsecured liability of the Corporation to
      Employee. Subaccounts (including Employee's Company Contribution
      Subaccount, In-Service Distribution Subaccount(s), and Retirement
      Subaccount) shall be maintained as determined necessary by the
      Corporation. Accounts and subaccounts are maintained solely as a device
      for the measurement and determination of the amounts to be paid to
      Employee or his Beneficiary pursuant to this Appendix A. Any reference to
      "contributions to" or "payments from" Employee's Accounts or subaccounts,
      or similar phrases, are for convenience only.

5.2   Timing of Contributions to and Distributions From Employee's Deferred
      Compensation Account. The Corporation shall credit to Employee's Deferred
      Compensation Account an amount equal to the percentage of Employee's Base
      Salary and Bonus which he has elected to defer in accordance with Section
      3.3, as of the last day of the calendar month in which Employee would have
      received

                                       11
<PAGE>

      such amount if not for Employee's deferral election.

      The Corporation shall credit to Employee's Deferred Compensation Account
      an amount equal to the Company Contribution(s) to which he is entitled
      under Sections 4.1 and 4.2 as soon as administratively practicable after
      the end of each calendar year.

      Any distribution with respect to Employee's Deferred Compensation Account
      shall be charged to such Account as of the date the distribution is made
      by the Corporation or from the Trust established in accordance with this
      Appendix A.

5.3   Selection of Investment Vehicle.

      Employee shall specify, in the manner prescribed by the Corporation, the
      allocation of his Account among investment indices available under this
      Appendix A. An individual's selection of an investment index will have no
      bearing on the actual investment or segregation of Corporation assets, but
      will be used as the basis for making adjustments to such individual's
      Account as described in Section Article 5.4 below. Employee can change his
      or her investment index or indices at such time, and in such manner, as
      determined by the Corporation. The Corporation may change the investment
      indices available under this Appendix A at any time in its absolute
      discretion.

5.4   Adjustment of Deferred Compensation Account.

      As of the last day of each calendar month, or more frequently as
      determined in the sole discretion of the Corporation, Employee's Deferred
      Compensation Account shall be credited with hypothetical net income, gain
      and loss, including hypothetical net unrealized gain and loss, based on
      the hypothetical investment directions made by the Participant in
      accordance with Section 5.3 of this Appendix A. Such earnings will
      continue to accrue during any period in which installments are paid
      pursuant to Section 6.1(a).

6. BENEFIT PAYMENTS.

                                       12
<PAGE>

6.1   Payment of Company Contribution Subaccount.

      (a) Payment upon Retirement. Payment of the vested portion of Employee's
      Company Contribution Subaccount shall be made, or shall commence, as soon
      as administratively practicable following Employee's Retirement, and the
      nonvested portion shall be forfeited. Payment shall be made in a lump sum
      unless Employee elects to receive payment of his Account under an Annual
      Installment Method, as defined below. Such election shall be made on a
      form prescribed by the Corporation, which must be received and accepted by
      the Corporation no later than the 13th month prior to Employee's
      Retirement date.

      "Annual Installment Method" shall mean annual installment payments over
      10, 15, or 20 years as elected by Employee, calculated as follows: (i) for
      the first annual installment, Employee's Company Contribution Subaccount
      balance shall be calculated as of the close of business on the last day of
      the calendar month immediately preceding the calendar month containing
      Employee's Retirement date, and (ii) for remaining annual installments,
      Employee's subaccount balance shall be calculated on the last day of the
      calendar month immediately preceding the calendar month containing the
      anniversary of Employee's Retirement Date. Each annual installment shall
      be calculated by multiplying this balance by a fraction, the numerator of
      which is one and the denominator of which is the remaining number of
      annual payments due to Employee. By way of example, if Employee elects a
      ten (10) year Annual Installment Method, the first payment shall be 1/10
      of Employee's Company Contribution Subaccount balance, calculated as
      described in this definition. The following year, the payment shall be 1/9
      of the Account balance, calculated as described in this definition, and so
      on.

      (b) Payment Upon Death. Death benefits shall be payable under this
      Appendix A only as follows:

            (i)   In the event Employee dies while employed by the Corporation,
            Employee's Company Contribution Subaccount shall be payable to
            Employee's Beneficiary in a lump sum as soon as administratively

                                       13
<PAGE>

            practicable following Employee's death.

            (ii)  In the event Employee dies after Retirement while receiving
            installment payments, installment payments shall cease and
            Employee's remaining vested Company Contribution Subaccount balance
            shall be paid to Employee's Beneficiary in a lump sum as soon as
            administratively practicable following Employee's death. In the
            event Employee dies after Retirement, but before any payment
            required under Section 6(a) has been paid to Employee, Employee's
            vested Company Contribution Subaccount balance shall be paid to
            Employee's Beneficiary in a lump sum as soon as administratively
            practicable following Employee's death.

6.2   Payment of In-Service Distribution Subaccount.

      Employee's In-Service Distribution Subaccount(s) shall be paid in a single
      lump sum. Payment shall be made as soon as administratively practicable
      after the earlier of (a) the Participant's In-Service Distribution Date,
      or (b) the date Employee terminates employment for any reason.

6.3   Payment of Retirement Subaccount.

      (a) Payment upon Retirement. In the event of Retirement Employee's
      Retirement Subaccount shall be paid at the same time, and in the same
      form, as Employee's Company Contribution Subaccount.

      (b) Payment upon Termination of Employment. In the event of Termination of
      Employment, Employee's Retirement Subaccount shall be paid in a single
      lump sum. Payments shall be made as soon as administratively practicable
      after the Participant's Termination of Employment.

6.4   Distribution of Taxable Amounts.

      Notwithstanding the foregoing provisions of this Section 6, in the event
      Employee or Employee's Beneficiary is determined to be subject to federal

                                       14
<PAGE>

      income tax on any amount credited to the Employee's Deferred Compensation
      Account prior to the time payment is otherwise due hereunder, the entire
      amount determined to be so taxable shall be paid from Employee's Account
      by the Corporation to Employee or Employee's Beneficiary. Any amount to
      the credit of Employee's Deferred Compensation Account shall be determined
      to be subject to federal income tax upon the earlier of:

      (a) determination by the Internal Revenue Service addressed to Employee or
      Beneficiary which is not appealed; or

      (b) a final determination by the United States Tax Court or any other
      Federal Court affirming any such determination by the Internal Revenue
      Service that amounts credited to Employee's Account are subject to federal
      income tax.

6.5   Timing of Distributions- Federal Law.

      Notwithstanding the foregoing provisions of this Section 6, benefit
      payments shall not be made or commence to Employee prior to the date
      otherwise permitted by federal law, as determined in the sole discretion
      of the Corporation.

7. LIMITATIONS ON LIABILITY.

   Notwithstanding any of the preceding provisions of this Appendix A, neither
   the Corporation, nor any individual acting as employee or agent of the
   Corporation, shall be liable to Employee or other person for any claim, loss,
   liability or expense incurred in connection with this Appendix A.

   The Corporation does not in any way guarantee Employee's Deferred
   Compensation Account against loss or depreciation, whether caused by poor
   investment performance, insolvency of a deemed investment or by any other
   event or occurrence. In no event shall the employees, officers, directors, or
   stockholders of the Corporation be liable to any individual or entity on
   account of any claim arising by reason of the provisions of this Appendix A
   or any instrument or instruments implementing its provisions, or for the
   failure of any Employee, Beneficiary or other individual or entity to be
   entitled to any particular tax consequences with

                                       15
<PAGE>

      respect to this Appendix A, or any credit or payment hereunder.

      Nothing contained in this Appendix A shall constitute a guarantee by the
      Corporation or any other person or entity that the assets of the
      Corporation will be sufficient to pay any benefits hereunder.

      Any payment made in good faith in accordance with provisions of this
      Appendix A shall be a complete discharge of any liability for the making
      of such payment under the provisions of this Appendix A.

8. EFFECT OF A CHANGE IN CONTROL OF THE CORPORATION. Anything in this Appendix A
to the contrary notwithstanding, this Section 8 shall apply in the event of a
Change in Control. If, within three years after the date of a Change in Control
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 benefit on the date of such
termination of employment. Employee's Deferred Compensation Account balance,
determined as of the valuation date immediately preceding Employee's termination
of employment, shall be payable in a lump sum as soon as administratively
practicable following such deemed Retirement Date.

Solely for purposes of this Section 8, "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) if Employee is a member of the Board
of Directors, the removal of Employee from, or the failure to re-elect Employee
as a member of, the Board, (iii) 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) (iv) 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 senior executives), (v) a material
breach of any provision of this Employment Agreement by the Corporation, (vi)
the

                                       16
<PAGE>

Corporation's requiring Employee to be based at a location that creates a
one-way commute for Employee 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.

9. EFFECT OF TERMINATION OF EMPLOYMENT AND REHIRE.

      Upon Employee's Retirement or 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). This Appendix A shall not apply to
      any subsequent period of reemployment of Employee by the Corporation. If,
      upon reemployment, Employee is receiving installment payments pursuant to
      Section 6(a) of this Appendix A those payments shall not be suspended
      during any period of reemployment.

10. ADMINISTRATION.

10.1. 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 10.3), 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

                                       17
<PAGE>

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

10.3. 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 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.

10.4. Reports and Records. The Board and those to whom the Board has delegated
      duties under Section 10.3 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.

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

11. UNFUNDED BENEFITS; ESTABLISHMENT OF TRUST.

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

11.2. 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

                                       18
<PAGE>

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.

11.3. 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.

11.4 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.

12. PAYMENT OF BENEFIT FOR DISABLED OR INCAPACITATED PERSON.

    If the Corporation determines, in its discretion, that Employee or
    Employee's Beneficiary 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 12 shall be a complete discharge of any
    liability for the making of such payment under this Appendix A. Nothing
    contained in this Section 12 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.

                                       19
<PAGE>

13. 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.

14. CLAIM PROCEDURE.

14.1. Presentation of Claim. Employee, or Employee's Beneficiary after
      Employee's death (such Employee 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 the contents of a notice
      received by the Claimant, the claim must be made within sixty (60) days
      after such notice was received by the Claimant. All other claims must be

      determination desired by the Claimant.

14.2. Notification of Decision. The Corporation shall consider a Claimant's
      claim within a reasonable time, but no later than ninety (90) days after
      receiving the claim. If the Corporation determines that special
      circumstances require an extension of time for processing the claim,
      written notice of the extension shall be furnished to the Claimant prior
      to the termination of the 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 shall indicate the special

                                       20
<PAGE>

      circumstances requiring an extension of time and the date by which the
      Corporation expects to render the benefit determination. The Corporation
      shall notify the Claimant in writing:

      (a) that the Claimant's requested determination has been made, and that
      the claim has been allowed in full; or

      (b) that the Corporation has reached a conclusion contrary, in whole or in
      part, to the Claimant's requested determination, and such notice must set
      forth in a manner calculated to be understood by the Claimant:

            (i) the specific reason(s) for the denial of the claim, or any part
            of it;

            (ii) specific reference(s) to pertinent provisions of this Appendix
            A upon which such denial was based;

            (iii) a description of any additional material or information
            necessary for the Claimant to perfect the claim, and an explanation
            of why such material or information is necessary;

            (iv) an explanation of the claim review procedure set forth in
            Section 14.3 below; and

            (v) a statement of the Claimant's right to bring a civil action
            under ERISA Section 502(a) following an adverse benefit
            determination on review.

14.3  Review of a Denied Claim. On or before sixty (60) days after receiving a
      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 Corporation a written request for a review of the denial of
      the claim. The Claimant (or the Claimant's duly authorized
      representative):

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

                                       21

      of, all documents, records and other information relevant to the claim for
      benefits;

      (b) may submit written comments or other documents; and/or

      (c) may request a hearing, which the Corporation, in its sole discretion,
      may grant.

14.4. Decision on Review. The Corporation shall render its decision on review
      promptly, and no later than sixty (60) days after the Corporation receives
      the Claimant's written request for a review of the denial of the claim. If
      the Corporation determines that special circumstances require an extension
      of time for processing the claim, written notice of the extension shall be
      furnished to the Claimant prior to the termination of the initial sixty
      (60) day period. In 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, records and other information submitted by the
      Claimant relating to the claim, 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:

      (a) specific reasons for the decision;

      (b) specific reference(s) to the pertinent provisions of this Appendix A
      upon which the decision was based;

      and other information relevant (as defined in applicable ERISA
      regulations) to the Claimant's claim for benefits; and

                                       22
<PAGE>

      (d) a statement of the Claimant's right to bring a civil action under
      ERISA Section 502(a).

14.5. Legal Action. A Claimant's compliance with the foregoing provisions of
      this Article 14 is a mandatory prerequisite to a Claimant's right to
      commence any legal action with respect to any claim for benefits under
      this Appendix A.

15. TAX WITHHOLDING AND REPORTING.

    (a) General: The Corporation shall have the right to deduct any required
    withholding taxes from any payment made under this Appendix A. Except as
    provided in Section 15(b), the Corporation shall not be obligated to pay or
    reimburse Employee, or his surviving spouse or Beneficiary, for any income
    or other taxes or penalties that may be imposed on such person by the
    Internal Revenue Service or any state or other taxing authority as a result
    of benefits paid under this Appendix A.

    (b) Excise Tax Payment. In the event that any payment or benefit (within the
    meaning of Section 280G(b)(2) of the Internal Revenue Code of 1986, as
    amended (the "Code")), to Employee or for his benefit paid or payable or
    distributed or distributable pursuant to the terms of this Employment
    Agreement (including this Appendix A) or otherwise in connection with, or
    arising out of, his employment with the Corporation or a Change in Control
    of the Corporation (a "Payment" or "Payments"), would be subject to the
