A separate calculation of Ceiling Excess Earnings shall be made with respect to post-1990 Deferral Account(s) using a rate of Moody's plus 3%.

Deferral Commitments

4.1

Deferral Elections

An eligible Executive or Director shall not become a Participant in the Plan unless and until he or she has executed and delivered to the Committee a Deferral election, including any forms or agreements as may be prescribed by the Committee, and the Committee shall have accepted such Deferral election and/or additional forms or agreements. To initially participate in the Plan, the Executive or Director must submit his or her Deferral election, including any forms or agreements prescribed by the Committee, during the applicable Deferral election period established by the Committee. Beginning with the deferral election made in the Plan Year ending January 31, 2004 for deferrals of Covered Compensation during calendar year 2004, the Participant's election shall be carried forward automatically to future Plan Years for which the Participant is eligible to participate unless, during the applicable election period for such future Plan Years, the Participant elects to modify or cancel the prior election under procedures established by the Committee.

Participants may elect to defer up to 100% but not less than 10% of Covered Compensation, in whole percentages, but not less than $1,000 (before reductions, if any, under Section 4.2.1).

4.2

Changes to Deferral Elections



4.2.1

The maximum allowable total deferral of Covered Compensation for all Participants under this Plan for any Plan Year will be determined by the Committee. In the event that Participant deferral elections are estimated to result in this maximum being exceeded, the following method will be used to reduce Participant deferral percentages so that the total estimated deferral is less than the maximum allowable.



a)

All Executives who have elected to defer more than 50% of Covered Compensation will be reduced, on an equal percentage basis, but not below 50% of Covered Compensation or $5,000, whichever is greater.



b)

If after implementation of subsection (a) above, the total deferral is still greater than the maximum allowable total deferral, all Executives' percentage deferrals will be reduced on an equal percentage basis until the maximum allowable total deferral is achieved.



4.2.2

Any Deferral election by a Participant shall be irrevocable for that Plan Year following the end of such Plan Year's Deferral election period.



4.2.3

The Committee, in its sole discretion, may elect to terminate the Plan at any time pursuant to Section 9; in such event, deferrals will cease effective as of the termination date.



4.3

Rollover of Balances from Current Deferred Compensation Plan



4.3.1

Participants who hold a balance in the Company's current Deferred Compensation Plan may elect to transfer that balance on a bookkeeping basis into this Plan at the beginning of the first Plan Year.

5.

Earnings on Participants' Accounts

5.1

Base Earnings on Deferral

5.1.1

Covered Compensation deferred by a Participant shall be credited to the Participant's Deferral Account as of the date of deferral. Interest in each Plan Year will be credited quarterly on the average Deferral Account balance for that quarter. The rate of interest applied to the Pre-1991 Deferral Account shall be at a base rate equivalent to an annual rate equal to Moody's Rate, and the rate applicable to the Post-1990 Deferral Account shall be at a base rate equivalent to an annual rate equal to the Moody's Rate less 1%. In each case, the Moody's Rate in effect on each Anniversary Date shall be used to determine the applicable rate of interest applied during the subsequent Plan Year.

5.2

Earnings on Rollover Balances

5.2.1

The portion of a Participant's Pre-1991 Deferral Account resulting from the transfer of a balance from the Company's current Deferred Compensation Plan will be credited quarterly with a rate of interest equivalent to 60% of the interest rate announced by Bank of America as its "prime rate" on the previous Anniversary Date for the first four (4) Plan Years. After the fourth Plan Anniversary Date, this portion of the Pre-1991 Deferral Account will be credited with interest quarterly at an effective annual rate equal to Moody's Rate plus 9% until the cumulative interest equals that amount of interest which would have been credited assuming that Moody's Rate had been used since Plan inception. At that time, the distinction between portions of the Pre-1991 Deferral Account from deferrals and from transfers will cease to exist.

5.3

Additional Earnings

5.3.1

The Committee may, in its sole discretion, determine whether and in what amount additional earnings shall be allocated to Participants' Deferral Accounts. Additional earnings in any Plan Year, if any, as determined by the Committee, will be allocated to each Participant's Deferral Account (except as otherwise provided in Section 6.1.3 and except for Deferral Accounts of Participants who have had a Termination of Employment prior to ten years of participation in the Plan) by the ratio of the Participant's Ceiling Excess Earnings to the sum of all Participants' Ceiling Excess Earnings as of the end of the Plan Year, with such additional earnings and Ceiling Excess Earnings calculated separately for Pre-1991 and Post-1990 Deferral Accounts.

6.

Payout of Participants' Accounts

6.1

Hardship

6.1.1

Notwithstanding the provisions of Sections 6.2 and 6.4 hereof, a Participant shall be entitled to request a hardship distribution of all or any portion of his or her Deferral Account(s). A Participant or legal representative of the Participant must make a written request for a hardship distribution, stating the reasons such withdrawal is necessary because of a financial hardship. The Committee, in its sole discretion, shall determine whether or not to grant the hardship distribution of such Participant's Deferral Account(s) and, in so doing, may rely on the Participant's statements, and a hardship distribution may be approved without further investigation unless the Committee has reason to believe such statements are false.

6.2

Termination Payouts

6.2.1

A Participant who has a Termination of Employment prior to one year of Plan Participation shall receive an amount equal to his or her Deferral Account, less any

4

credited earnings. Payment shall be made in a lump sum within twelve months following Termination of Employment.

6.2.2

A Participant who has a Termination of Employment after one year of Plan Participation but prior to 10 years of Plan participation shall receive payment in a lump sum within twelve months following Termination of Employment equal to his or her Deferral Account(s) as of the most recent quarterly valuation.



6.2.3

A Participant who has a Termination of Employment after 10 years of Plan participation shall be subject and entitled to the Normal Payout provisions set forth in Section 6.4.



6.3

Survivor Payouts



6.3.1

If a Participant dies before Normal Payout commences and the Plan Agreement is in effect at the time of death, the Employer shall make a Survivor Payout, as defined in Section 6.3.2, to the designated Beneficiary.



6.3.2

The Survivor Payout shall consist of the Participant's Deferral Account(s) at the time of death.



6.3.3

The Survivor Payout shall be paid in a lump sum to the Beneficiary within twelve months following verification of the Participant's death.



6.3.4

Notwithstanding subsection 6.3.3 above, a Participant may elect on the Beneficiary form provided by the Committee that the Survivor Payout be made over a 20-, 40-, or 60-quarter period rather than as a lump sum.



6.4

Normal Payouts



6.4.1

Normal Payouts shall commence at age sixty-five (65), Retirement or ten (10) years of Plan participation, whichever is the latest to occur.



6.4.2

A Participant who Retires may request that Normal Payout commence upon such Retirement. The Committee in its sole discretion may grant such request in the event that the Participant demonstrates financial need and the cash flow of the Company permits such early commencement.



6.4.3

The Participant shall elect to receive the Normal Payout over a 20-, 40- or 60-quarter period. The first payment will commence within 90 days of the quarter end following Retirement.



6.4.4

If a Participant does not elect a payout option, the payments shall be over a 20-quarter period.



6.4.5

Normal Payout shall consist of the Participant's Deferral Account(s) spread equally over the elected payout period. Earnings, and additional earnings, if applicable, as provided in Subsection 5.3.1, shall continue to be credited to the remaining Deferral Account(s) during the payout period and shall be estimated so that approximately equal payments can be made.



6.4.6

If a Participant dies during the Normal Payout period, Normal Payout shall continue as scheduled to the Participant's Beneficiary.



6.4.7

The election provided in Section 6.4.3 shall be made during the initial Commitment Period of Plan participation and shall become irrevocable at the end of such period.



6.5

Payment for Notification of Death

5

6.5.1

If a Participant dies following either Retirement or Termination of Employment, the Company will pay a $5,000 notification payment of a lump sum to the Participant's Beneficiary within 90 days of the quarter end following verification of the Participant's death.

7.

Beneficiary Designation

7.1

Upon forms provided by the Committee, each Participant shall designate in writing the Beneficiary or Beneficiaries whom such Participant desires to receive the benefits of this Plan, payable under Sections 6.3, 6.4 and/or 6.5, in the event of such Participant's death.

7.2

A Participant may from time to time change his or her designated Beneficiary or Beneficiaries without the consent of such Beneficiary or Beneficiaries by filing a new designation in writing with the Committee.

7.3

If a married Participant wishes to designate an individual other than his or her spouse as Beneficiary, such designation shall not be effective (i.e., the surviving spouse shall be treated as the sole Beneficiary) unless consented to in writing by the spouse, which consent shall acknowledge the effect of the designation and be witnessed by a member of the Committee (or an individual designated by the Committee) or acknowledged before a notary public. Notwithstanding the foregoing, spousal consent shall not be necessary if it is established to the satisfaction of the Committee that there is no spouse of the Participant or that the required consent cannot be obtained because the spouse cannot be located. The Company may rely upon the designation of Beneficiary or Beneficiaries last filed by the Participant in accordance with the terms of this Plan.

7.4

If the designated Beneficiary does not survive the Participant, or if there is no valid Beneficiary designation, amounts payable under the Plan shall be paid to the Participant's spouse, or if there is no surviving spouse, then to the duly appointed and currently acting personal representative of the Participant's estate. If there is no personal representative of the Participant's estate duly appointed and acting in that capacity within 60 days after the Participant's death, then all payments due under the Plan shall be payable to the person or persons who can verify by affidavit or court order to the satisfaction of the Committee that they are legally entitled to receive the benefits specified hereunder pursuant to the laws of intestate succession or other statutory provisions in effect at the Participant's death in the state in which the Participant resided.

7.5

In the event any amount is payable under the Plan to a minor, payment shall not be made to the minor, but instead shall be paid to that person's then living parent(s) to act as custodian, or, if no parent of that person is living, to a custodian selected by the Committee to hold the funds for the minor under the Uniform Transfers to Minors Act, or similar law, in effect in the jurisdiction in which the minor resides.

8.

Acceleration Provisions

8.1

Notwithstanding the provisions of Section 6 hereof, a Participant shall be entitled to request a hardship withdrawal of all or any portion of their Deferral Account or acceleration of payments of their Deferral Account if payments have already commenced under the payout option selected by the Participant. A Participant must make a written request to the Committee for a hardship withdrawal or request for accelerated payment, stating the reasons such withdrawal or acceleration is necessary because of a financial hardship. The Committee, in its sole discretion, shall determine whether or not to grant the Participant's request and, in so doing, may rely on the Participant's statements, and a hardship withdrawal or accelerated payment may be approved without further investigation unless the Committee has reason to believe such statements are false.

6

The Participant shall specify from which of their Deferral Account(s) (i.e., Pre-1991 or Post-1990, or both) the hardship withdrawal shall be taken.

8.2

The Committee, acting in its sole discretion, may determine to accelerate, in whole or in part, payments of some or all Deferral Account(s) (including Deferral Account(s) as to which payments have not yet commenced) in the event of a threatened or actual change in control of the Company, or in the event that a change in the legal, accounting, or tax treatment of amounts deferred under the Plan are altered in a manner which would potentially subject the Company, the Participants, or both, to adverse tax or administrative burdens.

9.

Amendment and Termination of Plan

9.1

The Company may, at its absolute and sole discretion, amend or terminate the Plan at any time.

9.2

In the event of Company-initiated Plan termination, Participants' entire Deferral Account(s), including credited interest, will be paid to Participants within twelve months of the quarter end following Plan termination.

10.

Nature of Accounts

10.1

All amounts credited to the Deferral Account(s) shall remain the sole property of the Company and shall be usable by it as part of its general funds for any legal purpose whatsoever. The Deferral Account(s) shall exist only as bookkeeping entries for the purpose of facilitating the computation of earnings credits hereunder and such Deferral Account(s) shall not constitute trust funds, escrow accounts, or any other form of asset segregation in favor of anyone other than the Company. No participant shall have any interest in any specific asset of the Company by virtue of this Plan and each Participant's rights under this Plan shall at all times be limited to those of a general unsecured creditor of the Company.

Although sometimes referred to in this Plan as "interest," amounts credited to Deferral Account(s) pursuant to Section 5.1, 5.2 and 5.3 may be treated as compensation for tax and payroll withholding purposes, pursuant to applicable Internal Revenue Code and Treasury regulation requirements.

11.

Limitation on Rights of Participants

11.1

If a Participant is an employee of the Company, such employment is not for any specific term and may be terminated by the Participant or Company at any time, for any reason, with or without cause. Neither this Plan nor any election to defer compensation hereunder shall be held or construed to confer on any person any legal right to be continued as an employee, consultant or Director of the Company; nor to constitute any promise or commitment by the Company regarding future positions, future work assignments, future compensation or any other term or condition of employment or affiliation.

12.

Non-Transferability

12.1

No right to payment under this Plan shall be subject to anticipation, alienation, sale, assignment, pledge, encumbrance, or charge and any attempt to anticipate, alienate, sell, assign, pledge, encumber, or charge the same shall be void. No right to payment shall in any manner be liable for, or subject to, the debts, contracts, liabilities or torts of the person entitled thereto.

13.

Restriction Against Assignment

13.1

The Participant or Beneficiary shall not have the power to transfer, assign, anticipate, modify, or otherwise encumber in any manner whatsoever any of the payments that will become due

7

pursuant to this Plan, nor shall said payments be subject to attachment, garnishment or execution, or be transferable by operation of law in event of bankruptcy or insolvency.

14.

Binding Effect

14.1

The Plan Agreement or Agreements attached hereto, when executed, is/are solely between the Company and the Participant. The Participant and any Beneficiary shall have recourse only against the Company for its enforcement, and any Plan Agreement shall be binding upon the Beneficiary, heirs, and personal representative of the Participant and upon the successors and assigns of the Company.

15.

Settlement of Disputes

15.1

If any disputes arise with regard to the interpretation of any of the provisions of this Plan or with regard to the amount of any payments due under this Plan and the Agreement, the Committee shall make any resolution of such disputes which it deems, in its sole discretion, to be in the best interest of the Company and the Participants. Any such determinations made by the Committee shall be final and binding on all Participants in the Plan.

15.2

The Committee shall adopt procedures, consistent with Section 503 of the Employee Retirement Income Security Act of 1974, with respect to notice to Participants of claims denied under the Plan and review of denied claims.

16.

Administration

16.1

The Plan shall be administered by the Committee, as appointed by the Board of Directors of the Company.

17.

Forfeiture

Any payment due to a Participant hereunder which is not claimed by the Participant, his or her Beneficiary, his or her estate or other person legally entitled thereto within four years after becoming payable shall be forfeited and canceled and shall remain with the Company and no other person shall have any right thereto or interest therein. The Company shall have no duty under this Agreement to give notice to any person other than the Participant or his or her designated Beneficiary that amounts are payable hereunder.
