shall construe and administer the Plan and shall have full authority to make
such rules and regulations deemed necessary or desirable to carry out such
administration. The Management Performance Committee may appoint an officer or
department to assist with the administration of the Plan. All interpretations of
the Plan by the Committee shall be final and binding on all parties, including
Participants, Beneficiaries and Employers.

4.   ELIGIBILITY.

     All officers and key managers whose annual Compensation is expected to
exceed the Compensation Limit and who participate in the Investment Plan are

5.   TRANSFER OF ACCOUNT BALANCES, DEFERRED SHARE PLAN.

     Any Deferred Shares allocated to an Employee's account balance under the
Deferred Share Plan prior to June 1, 1998, shall be transferred to this Plan as
of such date to the extent that such Deferred Shares are attributable to six
percent of Compensation deferred in excess of the Compensation Limit and can be
segregated from any Deferred Shares attributable to six percent of any
Compensation deferred pursuant to the Company's Deferred Compensation Plan.

6.   ELECTION TO DEFER COMPENSATION AND DEEMED INVESTMENT.

     (a) DEFERRAL ELECTION. Any Employee who has previously made an election to
defer Compensation for purposes of the Deferred Share Plan shall automatically
become a Participant in this Plan for 1998 and subsequent years at such time
that his/her Compensation exceeds the Compensation Limit. A deferral election,
once made, shall remain in effect for subsequent Plan Years until it is revoked
or modified by the Participant. A Participant can modify or revoke his/her
deferral election with respect to Compensation to be paid for future services by
submitting a new election or a revocation prior to the beginning of the Plan
Year in which such new deferral election or revocation is to become effective.
All notices of election or revocation shall be made on forms prepared by the
Company's Secretary and shall be dated, signed, and filed with the Company's
Secretary.

     (b) DEEMED INVESTMENT. Any amounts deferred by a Participant shall be
accounted for as if invested in shares of Common Stock purchased at a price
equal to the closing benchmark price of the Common Stock on the New York Stock
Exchange each payroll date. This amount shall be credited to a Participant's
account each payroll date as of January 1, 2002. In addition, a Participant's
account shall be credited on a quarterly basis with an amount equal to the
dividends that would have become payable during the deferral period if actual
purchases of Common Stock had been made, with such dividends accounted for as if
invested in Common Stock as of the payable date for such dividends. Any credited
shares treated as if they were purchased with dividends shall be deemed to have
been purchased at a price equal to the closing benchmark price of the Common
Stock on the dividend payment date. Each share of Common Stock that is

                                        3
<Page>

deemed to be purchased under this Paragraph 6(b) shall be reflected in a
Participant's account as a Deferred Share.

7.   MATCHING ALLOCATIONS.

     (a) AMOUNT. A Participant who makes an election under Section 6 is entitled
to the same Matching Allocations as are made under the terms of the Investment
Plan. The Matching Allocations are 100 percent for the first 3 percent of
contributed Compensation and 60 percent for the second 3 percent.

     If there are any Excess ESOP Allocations under the Investment Plan for a
Plan Year prior to 2000, a Participant shall be entitled to an additional
allocation under this Plan if he is employed by an Employer on the last day of
such Plan Year or if his employment terminated during such Plan Year as a result
of death, Disability or retirement. Such additional allocation shall be
calculated by multiplying the Compensation deferred by the Participant under the
Plan during the Plan Year by the same percentage used for the Excess ESOP
Allocation in the Investment Plan for the comparable year. Any Compensation
deferred pursuant to the Deferred Share Plan between January 1, 1998 and the
effective date of this Plan that is represented by Deferred Shares transferred
to this Plan shall be included in Compensation deferred pursuant to the terms of
this Plan for purposes of calculating the Excess ESOP Allocation.

     The amount of Matching Allocations shall be accounted for as if invested in
shares of Common Stock purchased at a price equal to the closing benchmark price
paid for shares of Common Stock reported on the New York Stock Exchange on the
applicable payroll date. Effective January 1, 2002, Common Stock deemed to have
been purchased with Matching Allocations shall be credited to a Participant's
account each payroll date.

     In addition, a Participant's account shall be credited on a quarterly basis
with an amount equal to the dividends that would have become payable during the
deferral period if actual purchases of Common Stock had been made, with such
dividends accounted for as if invested in Common Stock as of the payable date
for such dividends. Any credited shares treated as if they were purchased with
dividends shall be deemed to have been purchased at a price equal to the closing
benchmark price of the Common Stock on the dividend payment date. Each share of
Common Stock that is deemed to be purchased under this Section 7 shall be
reflected in the Participant's account as a Deferred Share.

     (b) VESTING. A Participant shall be vested in the portion of his account
attributable to Matching Allocations to the same extent as such Participant is
vested in any Matching Allocations credited to his account under the Investment
Plan.

8.   STATEMENT OF DEFERRED SHARE ACCOUNT.

     An annual statement shall be sent to each Participant within 60 days
following the end of each year showing for each preceding Plan Year the
Compensation deferred, Matching Allocations, Excess ESOP Allocations, the total
Deferred Shares credited to the Participant's account, and the number of these
Deferred Shares that are attributable to the Participant's deferred

                                        4
<Page>

Compensation, to Matching Allocations, Excess ESOP Allocations, and to
reinvested dividends. Such information shall be shown on a payroll date basis.

9.   PAYMENT OF ACCOUNT BALANCE.

     (a) PERIOD OF DEFERRAL. The Participant's prior deferral election(s) for
the Deferred Share Plan shall be applicable to this Plan for any amounts
transferred to this Plan. When making a first deferral election under Paragraph
(a) of Section 6, a Participant shall elect to receive all deferred
Compensation, Matching Allocations, and Excess ESOP Allocations either in a
lump-sum payment within 45 days following his death, Disability, or termination
of employment or in a number of annual installments (not to exceed four), the
first of which would be payable within 45 days following his death, Disability
or termination of employment with each subsequent payment payable one year
thereafter. The account balance shall be valued using the Fair Market Value of
the Company's Common Stock on the last day of the calendar month preceding
payment and shall be converted to a cash balance based upon such Fair Market
Value. Under an installment payout, the Participant's first installment shall be
equal to a fraction of the balance credited to his account as of the last day of
the calendar month preceding such payment, the numerator of which is one and the
denominator of which is the total number of installments selected. The amount of
each subsequent payment shall be a fraction of the balance in the Participant's
account as of the last day of the calendar month preceding each subsequent
payment, the numerator of which is one and the denominator of which is the total
number of installments elected minus the number of installments previously paid.

     (b) ADVERSE TAX DETERMINATION. If there is a determination by the Internal
Revenue Service (IRS) that a Participant should be taxed on some or all of the
amounts allocated to his account prior to the distribution date(s) elected under
Paragraph (a) of this Section 9, the Participant may elect to have all amounts
determined to be currently taxable paid to him immediately prior to the time he
must pay any taxes owed as a result of such IRS determination.

     (c) CHANGE IN CONTROL. Notwithstanding any other provision of this Plan, in
the event of a "Change in Control" of the Company, all Deferred Shares credited
to a Participant's account shall be converted to cash equal in amount to the
Fair Market Value of the Deferred Shares if converted into shares of the
Company's Common Stock. The cash shall be distributed to him within 60 days
following the Change in Control. The account balance shall be valued using the
Fair Market Value of the Company's Common Stock on the last day of the calendar
month preceding payment.

     A "Change in Control" of the Company shall be deemed to have occurred if
(i) any "Acquiring Person" (as such term is defined in the Rights Agreement
dated as of February 13, 1996, between the Company and U. S. Bank National
Association) is or becomes the beneficial owner (as such term is used in Rule
13d-3 under the Securities Exchange Act of 1934) of securities of the Company
representing 20 percent or more of the combined voting power of the Company; or
(ii) the following individuals cease for any reason to constitute a majority of
the number of directors then serving: individuals who, as of May 19, 1998,
constitute the Company's Board of Directors (Board) and any new director (other
than a director whose initial assumption of office is in connection with an
actual or threatened election contest, including but not limited

                                        5
<Page>

to a consent solicitation, relating to the election of directors of the Company)
whose appointment or election by the Board or nomination for election by the
Company's stockholders was approved or recommended by a vote of at least
two-thirds (2/3) of the directors then still in office who either were directors
on May 19, 1998, or whose appointment, election or nomination for election was
previously so approved or recommended; or (iii) the Company's stockholders
approve a merger or consolidation of the Company or any direct or indirect
subsidiary of the Company with any other corporation, other than a merger or
consolidation that would result in the voting securities of the Company
outstanding immediately prior to such merger or consolidation continuing to
represent (either by remaining outstanding or by being converted into voting
securities of the surviving entity or any parent thereof) at least 60 percent of
the combined voting power of the securities of the Company or such surviving
entity or any parent thereof outstanding immediately after such merger or
consolidation, or a merger or consolidation effected to implement a
recapitalization of the Company (or similar transaction) in which no person is
or becomes the beneficial owner, directly or indirectly, of securities of the
Company representing 25 percent or more of the combined voting power of the
Company's then outstanding securities; or (iv) the Company's stockholders
approve a plan of complete liquidation or dissolution of the Company or there is
consummated an agreement for the sale or disposition by the Company of all or
substantially all of the Company's assets, other than a sale or disposition by
the Company of all or substantially all of the Company's assets to an entity, at
least 60 percent of the combined voting power of the voting securities of which
are owned by stockholders of the Company in substantially the same proportions
as their ownership of the Company immediately prior to such sale. A Change in
Control, however, shall not be considered to have occurred until all conditions
precedent to the transaction, including but not limited to, all required
regulatory approvals have been obtained.

     (d) METHOD OF PAYMENT. All amounts credited to a Participant's account
shall be distributed to him or, in the event of his death, to his Beneficiary,
in cash and in accordance with the election made by the Participant.

     (e) SOURCE OF PAYMENTS. Each participating Employer will pay all benefits
for its Employees arising under this Plan.

10.  AMENDMENT AND TERMINATION OF PLAN.

     The Plan may be amended, modified or terminated by the Company's Board of
Directors at any time; provided, however, no such amendment, modification or
termination shall be made in the event there is a Change in Control, as defined
in Paragraph (c) of Section 9. In addition, no amendment, modification, or
termination shall reduce any deferred benefit under the Plan reflected in a
Participant's account prior to the date of such amendment or termination.

11.  NON-ASSIGNABILITY OF BENEFITS.

     To the extent consistent with applicable law, the Participant's deferred
benefits under this Plan shall not be assigned, transferred, pledged, or
encumbered or be subject in any manner to alienation or attachment.

                                        6
<Page>

12.  NO CREATION OF RIGHTS.

     Nothing in this Plan shall confer upon any Participant the right to
continue as an Employee or to receive annual Compensation in excess of the
Compensation Limit. The right of a Participant to receive a cash distribution
shall be an unsecured claim against the general assets of his Employer. Nothing
contained in this Plan nor any action taken hereunder shall create, or be
construed to create, a trust of any kind, or a fiduciary relationship between
the Company and the Participants, Beneficiaries, or any other persons. All
accounts under the Plan shall be maintained for bookkeeping purposes only and
shall not represent a claim against specific assets of any Employer.

13.  EFFECTIVE DATE.

     The Plan as originally adopted, was effective on May 19, 1998. The Plan, as
most recently amended and restated, is effective January 1, 2002, and shall
remain in effect until it is discontinued by action of the Company's Board of
Directors.

the initial option and all subsequent options granted to the Executive shall
contain a special provision that permits the Executive to have 30 days after
Termination of Employment (for reasons other than death, Disability, approved
retirement, or a Change in Control) to exercise the vested portion of any
options granted to him. (If the Executive's employment is terminated for one of
the specified reasons, he shall have longer periods of time in which to exercise
his options.) A copy of the Stock Plan and a copy of the form of Executive's
Option Agreement are attached to this Agreement as Exhibits B and C,
respectively.

     The Company shall also grant to Executive, in February of 2002, another
stock option to purchase at least 75,000 shares of the Company's common stock,
as part of the annual round of

                                        4

options granted to the Company's officers and key employees. As long as
Executive serves as an executive officer of the Company, the Company shall grant
a stock option to Executive when it takes action to grant stock options to other
officers and employees.

     RESTRICTED STOCK. As of the Agreement Date the Company shall grant 21,000
restricted shares of the Company's common stock to the Executive. One-third of
the grant (7,000 shares) shall vest and become nonforfeitable upon each
anniversary of the Agreement Date during the Employment Period, except that all
of the restricted shares shall immediately vest and become nonforfeitable in the
event of a Change in Control and that a pro rata portion of the remaining
restricted shares shall immediately vest and become nonforfeitable in the event
of the Executive's Termination of Employment for a reason other than Cause. A
copy of the form of Restricted Stock Grant is attached to this Agreement as
Exhibit D.

     Any shares of restricted stock granted as partial payment of bonuses earned
by Executive under the AMIP shall vest in accordance with the provisions set
forth in it.

     The Executive shall choose between recognizing ordinary income equal to the
value of the shares of restricted stock at time of grant or recognizing ordinary
income equal to the value of the shares of restricted stock as they vest and
become nonforfeitable. The Executive shall pay all withholding taxes
attributable to the recognition of income and may elect to use a portion of the
shares that would otherwise be distributed to satisfy such withholding
obligations.

     The shares of restricted stock granted to Executive in 2002 are included
within the shares reserved under the terms of the Stock Plan and are covered by
a registration statement filed with the Securities and Exchange Commission.

     STOCK OWNERSHIP. The Company requires all officers to own shares of the
Company's common stock. Executive shall be given the duration of the initial
Employment Period to own shares of the Company's common stock (including phantom
stock units) having a value equal to one times his annual compensation.

Plans") and shall be covered by the Company's nonqualified plan--the
Supplemental Executive Retirement Plan (the "SERP")--to make-up the difference
between what can be earned by and paid to the Executive under the Company's
qualified deferred benefit plan and what could be earned by and paid to the
Executive under such plan in the absence of federal tax law limitations
applicable to it. A copy of such Deferred Compensation Plan and the SERP are

Company will reimburse Executive for part or all of that the forfeited bonus, up
to a maximum reimbursement of $100,000.

     OTHER BENEFITS. During the Employment Period, the Executive shall be

                            TERMINATION OF EMPLOYMENT

     TERMINATION FOR CAUSE. If the Company terminates Executive's employment for
Cause, the Company shall only be required to pay Executive any earned but unpaid
base salary and vacation benefits.

     The Company may not terminate Executive's employment for Cause unless it
has: (a) officially given the Executive written notice at least 30 days prior to
the Date of Termination of its intent to terminate Executive's employment, that
contain a detailed description of the specific reasons that form the basis for
such action; (b) provided the Executive an opportunity to appear before the
Board prior to the Date of Termination to present arguments on his own behalf;
and (c) received the affirmative vote of at least two-thirds of the members of
the Board that it is proper to terminate the Executive's employment for Cause.
Pending the final resolution of any disputes concerning the Executive's
termination of employment for Cause, the Board may suspend Executive with pay.

     TERMINATION FOR DEATH OR DISABILITY. If Executive's employment terminates
during the Employment Period due to his death or Disability, the Company shall
pay to the Executive's beneficiaries (in the event of his death) or to the
Executive (in the event of his Disability), a lump-sum amount equal to the
Executive's Base Salary for the remainder of the Employment Period. The Company,
in accordance with the AMIP, shall also pay a pro rata portion of the annual
bonus that would have been paid to the Executive but for his death or
Disability; this bonus amount shall be paid in cash and shall be paid in
February of the year following the performance period and shall be prorated
based on the portion of the performance period that Executive was performing his
duties (in the event of his death) or receiving short-term disability benefits
(in the event of Disability). The Company shall also distribute a pro rata
portion of the one-time award of shares of stock previously granted to the
Executive on the Agreement Date and all shares of stock previously granted as
partial payment of the annual bonuses earned under the AMIP.

     TERMINATION WITHOUT CAUSE. If the Company terminates Executive's employment
during the Employment Period for some reason other than Cause, the Company shall
pay Executive a lump-sum amount equal to the Executive's Base Salary for the
remainder of the Employment Period and the Target Bonus amount for the year in
which his termination occurs. The Company shall also distribute a pro rata
portion of the one-time award of shares of stock previously granted to the
Executive on the Agreement Date and all shares of stock previously granted as
partial payment of the annual bonuses earned under the AMIP. The calculation of
any cash severance benefit shall be based on the Executive's Base Salary at the
time of termination.

     TERMINATION BY EXECUTIVE. The Executive can terminate his employment for
any reason, provided that he gives the Board written notice at least 30 days'
prior to his Date of Termination. If the Executive terminates his employment for
other than Good Reason, he shall only be paid his earned but unpaid Base Salary
and accrued vacation benefits (up to time of termination).

     If the Executive terminates his employment for Good Reason, the Company
shall pay Executive a lump sum amount equal to his Base Salary for the remainder
of the Employment Period

                                        7
<Page>

and the Target Bonus for the year in which the termination occurs. The Company
shall also distribute a portion of the one-time award of shares of stock
previously granted to the Executive on the Agreement Date and all shares of
stock previously granted as partial payment of the annual bonuses earned under
the AMIP. The calculation of any cash severance benefit shall be based on the
Executive's Base Salary at the time of termination.

                                    ARTICLE 8
                              RESTRICTIVE COVENANTS

     NON-SOLICITATION OF EMPLOYEES. During the remainder of any Employment
Period for which the Executive is receiving compensation as a result of a
Termination of Employment and during the one-year period immediately following a
Termination of Employment for Cause or Termination by Executive for other than
Good Reason, the Executive shall not directly or indirectly employ or seek to
employ any employees of the Company or its Subsidiaries and shall not entice or
otherwise encourage any such employee to leave such employment.

     CONFIDENTIALITY. During the Employment Period, the Executive shall maintain
the confidential nature of information concerning the Company's financial
results and business strategies and shall not disclose such information to any
person whose interests are or may be adverse to the Company's interests or any
person that may use such information to obtain personal financial gain. After a
Termination of Employment for any reason, the Executive shall not, without the
prior written consent of the Company or as may otherwise be required by law or
legal process, communicate or divulge any confidential information other than
the Company and its designees.

     INJUNCTION. Executive acknowledges that monetary damages will not be an
adequate remedy for the Company in the event he breaches the provisions of this
Article. Consequently, Executive agrees that the Company is entitled to an
injunction to prevent Executive from any breach of the provisions of this
Article in addition to other rights that the Company may have.

                                    ARTICLE 9
                                  MISCELLANEOUS

     BENEFICIARY. If Executive dies prior to receiving all of the amounts
payable to him in accordance with the terms of this Agreement, such amounts
shall be paid to one or more beneficiaries designated by Executive in writing to
the Company during his lifetime, or if no such beneficiary is designated, to
Executive's estate. Such payments shall be made in a lump sum to the extent so
payable and, to the extent not payable in a lump sum, in accordance with the
terms of this Agreement. Executive, without the consent of any prior
beneficiary, may change his designation of beneficiary or beneficiaries at any
time or from time to time by submitting to the Company a new designation in
writing.

     ASSIGNMENT: SUCCESSORS. The Company may not assign its rights and
obligations under this Agreement without the prior written consent of Executive
except to a successor of the Company's business that expressly assumes the
Company's obligations in writing. This Agreement shall be

Beneficiaries, the Company and the successors and permitted assigns of the
Company.

     NONALIENATION. Benefits payable under this Agreement shall not be subject
in any manner to anticipation, alienation, sale, transfer, assignment, pledge,
encumbrance, charge, garnishment, execution of levy of any kind, either
voluntary or involuntary, prior to actually being received by Executive or a
beneficiary, as applicable, and any such attempt to dispose of any right to
benefits payable hereunder shall be void.

     SEVERABILITY. If one or more parts of this Agreement are declared by any
court or governmental authority to be unlawful or invalid, such unlawfulness or
invalidity shall not invalidate any part of this Agreement not declared to be
unlawful or invalid. Any part so declared to be unlawful or invalid shall, if
possible, be construed in a manner which will give effect to the terms of such
part to the fullest extent possible while remaining lawful and valid.

     AMENDMENT: WAIVER. This Agreement shall not be amended or modified except
by written instrument executed by the Company and Executive. A waiver of any
term, covenant or condition contained in this Agreement shall not be deemed a
waiver of any other term, covenant or condition, and any waiver of any default
in any such term, covenant or condition shall not be deemed a waiver of any
later default thereof.
