                  (1)      is the monthly disability retirement benefit to which
                           the Executive would have been entitled under the
                           Retirement Plan as of his Benefit Commencement Date
                           if the Final Average Compensation multiplier under
                           the Retirement Plan's benefit formula were 2.05% in
                           lieu of the multiplier in effect under such plan
                           (1.5% in 2001), calculated without regard to the
                           limits described in Section 4.1(b)(1)(A) and (B)
                           hereof, and

                  (2)      is the vested monthly disability retirement benefit
                           payable to the Executive under the Supplemental Plan
                           and the Retirement Plan if benefits were to commence
                           as of the Executive's Benefit Commencement Date.

                  For purposes of calculating (1) above, and notwithstanding
                  anything else contained in the Retirement Plan, the monthly
                  retirement benefit under the Retirement Plan shall be
                  calculated by giving the Executive the following additional
                  Credited Service:

                                       8
<PAGE>   9

                  (A)      for the period beginning April 1, 1998 and ending on
                           March 31, 2003, five additional years of Credited
                           Service if the Executive is still employed by the
                           Company on March 31, 2003; plus

                  (B)      for each year and month of Credited Service the
                           Executive receives under the Retirement Plan after
                           March 31, 2003, the Executive will actually receive
                           two times the years and months of Credited Service
                           received in accordance with the Retirement Plan.

         (c)      COMMENCEMENT AND DURATION. Payment of benefits under this
                  Section 4.4 shall begin on the Executive's Benefit
                  Commencement Date.

                  The Executive who is receiving a benefit under this section
                  shall not be entitled to any other benefit under this Article
                  or Article 5. Benefits under this section shall be subject to
                  rules comparable to the disability retirement benefit rules in
                  the Retirement Plan concerning duration, entitlement to and
                  amounts of other retirement benefits, medical examinations,
                  and other restrictions.

         4.5      VESTED BENEFITS ON OTHER TERMINATIONS OF EMPLOYMENT

         (a)      ELIGIBILITY. If the Executive, upon a Termination of Service
                  (other than normal, early, late, or disability retirement
                  described in Sections 4.1 through 4.4), is entitled to a
                  vested benefit under the Retirement Plan, he shall be eligible
                  for a benefit under this Section 4.5. Except as otherwise
                  provided in Section 7, this benefit shall be calculated as a
                  single life annuity corresponding to the standard form of
                  benefit under the Retirement Plan.

         (b)      AMOUNT. The Executive, if eligible for a benefit under
                  subsection (a) shall be entitled to a monthly benefit under
                  this Agreement equal to the difference between paragraphs (1)
                  and (2) where --

                  (1)      is the monthly benefit to which the Executive would
                           have been entitled under the Retirement Plan as of
                           his Benefit Commencement Date if the Final Average
                           Compensation multiplier under the Retirement Plan's
                           benefit formula were 2.05% in lieu of the multiplier
                           in effect under such plan (1.5% in 2001), calculated
                           without regard to the limits described in Section
                           4.1(b)(1)(A) and (B) hereof, and

                  (2)      is the vested monthly benefit payable to the
                           Executive under the Supplemental Plan and the
                           Retirement Plan if benefits were to commence as of
                           the Executive's Benefit Commencement Date.

                  For purposes of calculating (1) above, and notwithstanding
                  anything else contained in the Retirement Plan, the monthly
                  retirement benefit under the Retirement Plan

                                       9
<PAGE>   10

                  shall be calculated by giving the Executive the following
                  additional Credited Service:

                  (A)      for the period beginning April 1, 1998 and ending on
                           March 31, 2003, five additional years of Credited
                           Service if the Executive is still employed by the
                           Company on March 31, 2003; plus

                  (B)      for each year and month of Credited Service the
                           Executive receives under the Retirement Plan after
                           March 31, 2003, the Executive will actually receive
                           two times the years and months of Credited Service
                           received in accordance with the Retirement Plan.

         (c)      COMMENCEMENT. Payment of benefits under this Section 4.5 shall
                  begin on this Executive's Benefit Commencement Date. If the
                  Executive's Benefit Commencement Date is accelerated by the
                  Administrator before the Retirement Plan's "Early Retirement
                  Date," the benefits under this section shall be adjusted to be
                  the Actuarial Equivalent of the benefits that would be payable
                  hereunder if such benefit commenced at the Executive's Early
                  Retirement Date. If the Executive's Benefit Commencement Date
                  is delayed by the Administrator beyond the Executive's Normal
                  Retirement Date, the benefits under this section shall be
                  adjusted to be the Actuarial Equivalent of the benefits that
                  would be payable hereunder if such benefits commenced at the
                  Executive's Normal Retirement Date.

         4.6      REEMPLOYMENT

         If the Executive, after Termination of Service, is subsequently
reemployed by the Company, the Executive and his benefits hereunder shall become
subject to rules comparable to the rules in the Retirement Plan regarding
suspension of benefits, recalculation of benefits, and similar items.

5.       CHANGE IN CONTROL AND TERMINATION WITHOUT CAUSE BENEFITS

         For purposes of this Agreement, a "Change in Control" shall have the
meaning contained in Section 1(b)(v) of that certain Amended and Restated Change
in Control, Severance and Non-Competition Agreement entered into by the Company
and Executive and dated as of April 20, 1999, a copy of which definition is
attached hereto as Exhibit A. For purposes of this Agreement, "Termination
Without Cause" shall mean any instance not covered under the definition of
"Termination for Cause" as contained in Section 1(a)(ii) of that certain Amended
and Restated Change in Control, Severance and Non-Competition Agreement entered
into by the Company and Executive and dated as of April 20, 1999, a copy of
which definition is attached hereto as Exhibit B.

                                       10
<PAGE>   11

         In the event that the Company experiences a Change in Control or should
the Executive be Terminated Without Cause, all benefits calculated pursuant to
Sections 4.1 through 4.5 above shall be calculated as if:

         (1)      the Executive were still employed on the later of August 15,
                  2004 (which is the date on which Executive attains the age of
                  fifty-eight (58) years) and three years from the applicable
                  event, and the Executive continued to receive Credited Service
                  through the later of August 15, 2004 and three years from the
                  applicable event under the terms of this Plan;

         (2)      the Executive attained the later of age fifty-eight (58) and
                  the age he will be three years from the applicable event;

         (3)      the Executive met the eligibility requirements for early
                  retirement under the Retirement Plan on said date; and

         (4)      the Executive was fully vested in the benefits payable under
                  this Plan (whether or not he is then vested under the
                  Retirement Plan or the Supplemental Plan) on said date.

         Additionally, such benefits shall be based on Covered Compensation (as
defined in the Retirement Plan) as of his Termination of Service. For purposes
of determining Final Average Compensation as of the later of August 15, 2004 and
three years from the applicable event, the calculation will also assume that the
Executive continues to receive Compensation (as defined in the Retirement Plan)
from the date of his Termination of Service through the later of August 15, 2004
and three years from the applicable event equal to the yearly amount payable to
him pursuant to paragraphs 1(b)(i)(A) and (C) of that certain Amended and
Restated Change in Control, Severance and Non-Competition Agreement entered into
by Executive and Company and dated as of April 20, 1999, as the same may be
amended from time to time.

         Finally, the Executive shall be entitled to make any benefit
commencement elections pursuant to this Agreement on said date as if he attained
the later of age fifty-eight (58) and the age he will be three years from the
applicable event provided, however, such assumed age shall not be applicable for
determining the Actuarial Equivalent of benefits under Section 7.

6.       DEATH BENEFIT

         6.1      ELIGIBILITY

         If the Executive has accrued vested rights under the Retirement Plan
and dies before the date on which his benefits under Section 4 hereof are to
commence, and his spouse or children under the age of 21 are entitled to death
benefits under the Retirement Plan, such spouse or children shall become
eligible for death benefits under this section.

                                       11
<PAGE>   12

         6.2      AMOUNT

         A spouse or child of the Executive who is eligible for a death benefit
under Section 6.1 shall be entitled to a benefit under this Agreement equal to
the difference between subsections (1) and (2) where--

         (1)      is the vested death benefit to which the spouse or child would
                  have been entitled under the Retirement Plan if the Final
                  Average Compensation multiplier under the Retirement Plan's
                  benefit formula were 2.05% in lieu of the multiplier in effect
                  under such plan (1.5% in 2001) as of the earliest date on
                  which such benefit would be payable, calculated without regard
                  to the limits described in Section 4.1(b)(1)(A) and (B)
                  hereof, and

         (2)      is the death benefit payable to the spouse or child under the
                  Supplemental Plan and the Retirement Plan if such benefits
                  were to commence as of such earliest date of payment.

                  For purposes of calculating (1) above, and notwithstanding
                  anything else contained in the Retirement Plan, the monthly
                  retirement benefit under the Retirement Plan shall be
                  calculated by giving the Executive the following additional
                  Credited Service:

                  (A)      for the period beginning April 1, 1998 and ending on
                           March 31, 2003, five additional years of Credited
                           Service if the Executive is still employed by the
                           Company on March 31, 2003; plus

                  (B)      for each year and month of Credited Service the
                           Executive receives under the Retirement Plan after
                           March 31, 2003, the Executive will actually receive
                           two times the years and months of Credited Service
                           received in accordance with the Retirement Plan.

         6.3      FORM, TIMING, AND DURATION

         Payment of benefits under this section shall begin at the earliest
possible date such benefits would be payable to the spouse or child, as
applicable, under the Retirement Plan. Payments shall continue for the duration
described in the Retirement Plan. Payment shall be in the standard form for such
benefits described in the Retirement Plan.

         Notwithstanding the foregoing, the Administrator may, in its sole and
absolute discretion, direct that payment be made in a form or at a time other
than that described above. In that event, the benefits payable shall be the
Actuarial Equivalent of the benefits described in the first paragraph of this
section.

                                       12
<PAGE>   13

7.       FORM OF PAYMENT

         7.1      UNMARRIED PARTICIPANT.

         The form of payment for the Executive if he is not married on his
Benefit Commencement Date shall be a single life annuity.

         7.2      MARRIED PARTICIPANT.

         The form of payment for the Executive if he is married on his Benefit
Commencement Date shall be a statutory joint and survivor spouse annuity. A
statutory joint and survivor spouse annuity provides--

         (a)      a monthly benefit to the Executive for life; and

         (b)      upon the Executive's death, a monthly benefit to the
                  Executive's surviving spouse for life equal to 50 percent of
                  the monthly amount payable during the Executive's lifetime.

         This statutory joint and survivor annuity shall be the Actuarial
Equivalent of the single life annuity in Section 7.1.

         7.3      OPTIONAL PAYMENT FORMS

         The Administrator may, in its sole and absolute discretion, direct that
payment be made in a form other than that described in Section 7.1 or 7.2. In
that event, the benefit payable under the optional payment form shall be the
Actuarial Equivalent of the single life annuity described in Section 7.1.

8.       RETIREMENT BENEFIT ENHANCEMENT

         In the event that the benefit multiplier applicable to other senior
executives under the Supplemental Plan is increased in the future, then benefits
payable to the Executive under Article IV, V or VI hereof shall be increased by
$6,000 for each year of Credited Service (without applying the special
adjustment for determining Credited Service in Section 4.1(b), 4.2(b), 4.3(b),
4.4(b), 4.5(b) and 6.2).

9.       FUNDING

         9.1      STATUS AS UNFUNDED PLAN

         The Agreement is intended to constitute an unfunded plan maintained for
a "select group of management or highly compensated employees" within the
meaning of Section 201(2) of the Employee Retirement Income Security Act of
1974. The benefits under this Agreement shall be

                                       13
<PAGE>   14

paid from the general assets of the Company, or from a trust fund the assets of
which remain available to the general creditors of the Company in the event of
its insolvency. The benefits shall not be funded in advance in any way except,
in the Company's discretion, through such a trust.

         9.2      EVENT UPON WHICH TRUST WILL BE FUNDED

         Nothing contained in this Agreement, and no action taken pursuant to
the provisions of this Agreement, shall create a trust or fiduciary relationship
between the Company and the Executive, Executive's spouse, or Beneficiary.
Notwithstanding the foregoing, the Company may establish and fund a trust for
said purpose, in which event the assets of the trust shall nonetheless be
available to the general creditors of the Company in the event of its
insolvency. In the event that the Company experiences a Change in Control, as
described in Section 5 above, it will immediately deposit into such a trust an
amount of money, calculated by actuaries acceptable to the Executive, which will
be sufficient with any other assets then held in said trust for said purpose to
fund the obligation of the company under this Agreement. Any such trust will be
designed to avoid creating a funded promise hereunder for purposes of applicable
Internal Revenue Service and Department of Labor regulations relating to
constructive receipt of income and applicability of funding requirements of
ERISA.

         9.3      UNSECURED INTEREST

         Neither the Executive nor any Beneficiary shall have any interest
whatsoever in any specific asset of the Company or an Affiliate. To the extent
that any person acquires a right to receive payments under this Agreement, such
right shall be no greater than the right of any unsecured general creditor of
the Company.

10.      MISCELLANEOUS PROVISIONS

         10.1     ADMINISTRATION

         The Agreement shall be administered by the Administrator.

         The Administrator shall have all powers necessary or appropriate to
carry out the provisions of the Agreement. It may, from time to time, establish
rules for the administration of the Agreement and the transaction of the
Agreement's business.

         The Administrator shall have the exclusive right to make any finding of
fact necessary or appropriate for any purpose under the Agreement including, but
not limited to, the determination of eligibility for and amount of any benefit.

         The Administrator shall have the exclusive right to interpret the terms
and provisions of the Agreement and to determine any and all questions arising
under the Agreement or in connection with its administration, including, without
limitation, the right to remedy or resolve

                                       14
<PAGE>   15

possible ambiguities, inconsistencies, or omissions by general rule or
particular decision, all in its sole and absolute discretion.

         All findings of fact, determinations, interpretations, and decisions of
the Administrator shall be conclusive and binding upon all persons having or
claiming to have any interest or right under the Agreement and shall be given
the maximum deference allowed by law.

         10.2     APPEALS FROM DENIAL OF CLAIMS

         If any claim for benefits under the Agreement is wholly or partially
denied, the claimant shall be given notice of the denial. This notice shall be
in writing, within a reasonable period of time after receipt of the claim by the
Administrator. This period shall not exceed 90 days after receipt of the claim,
except that if special circumstances require an extension of time, written
notice of the extension shall be furnished to the claimant, and an additional 90
days will be considered reasonable.

         This notice shall be written in a manner calculated to be understood by
the claimant and shall set forth the following information:

         (a)      the specific reasons for the denial;

         (b)      specific reference to the Agreement provisions on which the
                  denial is based;

         (c)      a description of any additional material or information
                  necessary for the claimant to perfect the claim and an
                  explanation of why this material or information is necessary;

         (d)      an explanation that a full and fair review by the
                  Administrator of the decision denying the claim may be
                  requested by the claimant or an authorized representative by
                  filing with the Administrator, within 60 days after the notice
                  has been received, a written request for the review; and

         (e)      if this request is so filed, an explanation that the claimant
                  or an authorized representative may review pertinent documents
                  and submit issues and comments in writing within the same
                  60-day period specified in subsection (d).

         The decision of the Administrator upon review shall be made promptly,
and not later than 60 days after the Administrator's receipt of the request for
review, unless special circumstances require an extension of time for
processing. In this case the claimant shall be so notified, and a decision shall
be rendered as soon as possible, but not later than 120 days after receipt of
the request for review. If the claim is denied, wholly or in part, the claimant
shall be given a copy of the decision promptly. The decision shall be in
writing, shall include specific reasons for the denial, shall include specific
references to the pertinent Agreement provisions on which the denial is based,
and shall be written in a manner calculated to be understood by the claimant.

<PAGE>   16

         10.3     EXPENSES

         All expenses incurred in the administration of the Agreement shall be
paid by the Company.

         10.4     AMENDMENT AND TERMINATION

         The Company and the Executive hereby reserve the right to amend,
modify, or terminate the Agreement at any time, and for any reason, by action of
the Board of Directors of the Company and by the Executive, in writing. However,
no amendment or termination shall have the effect of reducing the benefits
accrued by the Executive prior to the date of the amendment or termination.

         10.5     NO CONTRACT OF EMPLOYMENT

         Nothing contained in this Agreement shall be construed to give the
Executive the right to be retained in the service of the Company or its

                  (v)      For purposes of this Agreement, "Change in Control"
shall mean:

                           (A)      The Company is merged, consolidated or
reorganized into or with another corporation or other legal person, and as a
result of such merger, consolidation or reorganization less than a majority of
the combined voting power of the then-outstanding securities of such corporation
or person immediately after such transaction are held in the aggregate by the
holders of Voting Stock (as that term is hereafter defined) of the Company
immediately prior to such transaction;

                           (B)      The Company sells or otherwise transfers all
or substantially all of its assets to another corporation or other legal person,
and as a result of such sale or transfer less than a majority of the combined
voting power of the then-outstanding securities of such corporation or person
immediately after such sale or transfer is held in the aggregate by the holders
of Voting Stock of the Company immediately prior to such sale or transfer;

                           (C)      There is a report filed on Schedule 13D or
Schedule 14D-1 (or any successor schedule, form or report), each as promulgated
pursuant to the Securities Exchange Act of 1934, as amended (the "Exchange
Act"), disclosing that (x) any person (as the term "person" is used in Section
13(d)(3) or Section 14(d)(2) of the Exchange Act) has become the beneficial
owner (as the term "beneficial owner" is defined under Rule 13d-3 or any
successor rule or regulation promulgated under the Exchange Act) of securities
representing 15% or more of the combined voting power of the then-outstanding
securities entitled to vote generally in the election of directors of the
Company ("Voting Stock"), or (y) any person has, during any period, increased
the number of shares of Voting Stock beneficially owned by such person by an
amount equal to or greater than 15% of the outstanding shares of Voting Stock;
provided, however, that transfers of shares of Voting Stock between a person and
the affiliates or associates (as such terms are defined under Rule 12b-2 or any
successor rule or regulation promulgated under the Exchange Act) of such person
shall not be considered in determining any increase in the number of shares of
Voting Stock beneficially owned by such person;

                           (D)      The Company files a report or proxy
statement with the Securities and Exchange Commission pursuant to the Exchange
Act disclosing in response to Form 8-K or Schedule 14A (or any successor
schedule, form or report or item therein) that a change in control of the
Company has occurred or will occur in the future pursuant to any then-existing
contract or transaction; or

                           (E)      If, during any period of two consecutive
years, individuals who at the beginning of any such period constitute the
Directors of the company cease for any reason to constitute at least a majority
thereof; provided, however, that for purposes of this clause (v) each Director
who is first elected, or first nominated for election by the Company's
stockholders, by a vote of at least two-thirds of the Directors of the Company
(or a committee thereof) then still in

                                       18
<PAGE>   19

office who were Directors of the Company at the beginning of any such period
will be deemed to have been a director of the Company at the beginning of such
period.

         Notwithstanding the foregoing provisions of Sections (C) or (D) unless
otherwise determined in a specific case by majority vote of the Board, a "Change
in Control" shall not be deemed to have occurred by purposes of Sections (C) or
(D) solely because (1) the Company, (2) an entity in which the Company directly
or indirectly beneficially owns 50% or more of the voting securities (a
"Subsidiary"), or (3) any employee stock ownership plan or any other employee
benefit plan of the Company or any Subsidiary either files or becomes obligated
to file a report or a proxy statement under or in response to Schedule 13D,
Schedule 14D-1, Form 8-K or Schedule 14A (or any successor schedule, form or
report or item therein) under the Exchange Act disclosing beneficial ownership
by it of shares of Voting Stock, whether in excess of 15% or otherwise, or
because the Company reports that a change in control of the Company has occurred
or will occur in the future by reason of such beneficial ownership.

Executive's conviction for, or guilty plea to, a felony or a crime involving
moral turpitude, (B) the Executive's commission of an act of personal dishonesty
in connection with his employment by the Company, (C) a breach of fiduciary duty
in connection with his employment with the Company which shall include, but not
be limited to, (1) investment in any person or organization with the knowledge
that such person or organization has or proposes to have dealings with the
Company, such person or organization competes with the Company, or the Company
is considering an investment in such person or organization (the reference to
"organization" excludes federal credit unions, publicly owned insurance
companies and corporations the stock of which is listed on a national securities
exchange or quoted on NASDAQ if the direct and beneficial stock ownership of the
Executive, including members of his immediate family, is not more than one
percent (1%) of the total outstanding stock of such corporation); (2) a loan
(including a guaranty of a loan) from or to any person or organization having or

the Executive's employment as a result of his death or disability (if such
Executive is eligible for benefits under the Company's long-term disability plan
or would be eligible for such benefits were the Executive a participant in said
plan) shall constitute a termination by the Company with Cause for purposes of
this Agreement.
