Participant only if and when such Participant permanently ceases, for whatever
reason (whether voluntary or involuntary and including death or Disability), all

prior to the Effective Date hereof, re-commenced employment with any Covered
Employer, such Participant shall be credited with Service Years for those
periods prior to the Effective Date hereof during which he was actually employed
by any Covered Employer notwithstanding the fact that such pre-Effective Date
employment with such covered Employer(s) was not continuous.  Except as
otherwise provided in Section 3.04 hereof (concerning leaves of absence), it is
intended that a Participant shall cease earning Service Years upon his incurring
any Termination after the Effective Date hereof, regardless of whether such

          as of such Participant's Termination Date and also has been married

                 Amount shall be 50% of the amount of the monthly Primary Social
                 Security Benefit (as calculated by the Board under paragraph
                 (iii) below) to which such Participant is entitled following
                 such Termination.

          (ii)   In the case of any Participant whose Termination does not
                 constitute Normal Retirement (either because such Termination
                 does not constitute Retirement or because such Termination
                 constitutes Early Retirement), such Participant's Social
                 Security Offset Amount shall be 50% of the amount of the
                 monthly Primary Social Security Benefit (as calculated by the
                 Board under paragraph (iii) below) to which such Participant
                 would be entitled commencing on his Normal Benefit Date paid to
                 such Participant in the Normal Benefit Form if, with respect to
                 the period (if any) between such Participant's Termination Date
                 and his Normal Benefit Date, (A) such Participant had continued
                 to earn a constant monthly salary equal to the Participant's
                 Compensation for the month immediately preceding the month of
                 such Participant's Termination, and (B) the Social Security
                 wage base and other provisions of the Social Security law
                 relevant to the determination of benefits thereunder (including
                 any applicable regulations and/or other pronouncements, such as
                 wage base and other provisions) in effect as of such
                 Participant's Termination Date had remained unchanged.

          (iii)  Each Participant shall submit to the Board, for use in
                 calculating such Participant's Primary Social Security Benefit
                 and the corresponding Social Security Offset Amount under
                 paragraphs (i) or (ii) above, as applicable, either (A) a
                 written earnings history obtained from the Social Security
                 Administration, or (B) written evidence satisfactory to the
                 Committee showing that, such Participant has never earned wages
                 subject to the jurisdiction of the U.S. Social Security system
                 (e.g., a foreign

                 Participant with no U.S. wages). In the event a Participant
                 fails to comply with the requirements of the preceding sentence
                 within 90 days following such Participant's Payment
                 Commencement Date, the Participant's Primary Social Security
                 Offset Benefit (for purposes of calculating his Social Security
                 Offset Amount under paragraphs (i) or (ii) above, as
                 applicable) shall be determined by the Committee using an
                 estimated wage history, applying a salary scale projected
                 backwards from the Participant's Retirement Date, and based on
                 (I) for the two years prior to the Participant's Retirement
                 Date, an increase of six percent (6%) per annum, and (II) for
                 the period prior to such two year period, the actual change in
                 average wages from year to year as determined by the Social
                 Security Administration. Such estimated wage history shall be
                 deemed correct for all purposes of this Plan.

     (b)  A Participant's "Qualified Plan Offset Amount" shall be the sum of the
          Defined Benefit Plan Offset Amount and the 401(k) Plan Offset Amount
          determined with respect to such Participant under the following
          provisions, as applicable:

          (i)    With respect to any Participant who was a Participant in the
                 Defined Benefit Plan, such Participant's "Defined Benefit Plan
                 Offset Amount" shall be the employer-provided portion (i.e.,
                 the portion attributable to employer contributions) of the
                 amount of the monthly annuity payment to which such Participant
                 would be entitled under the Defined Benefit Plan if his benefit
                 thereunder were paid in the Normal Benefit Form commencing on
                 his Normal Benefit Date. The "Defined Benefit Plan Offset
                 Amount" shall be zero with respect to any Participant who was
                 not a participant in the Defined Benefit Plan, or to any
                 Participant who would have become a participant in the Defined
                 Benefit Plan following the date such Plan's benefit accruals
                 were frozen.

          (ii)   With respect to any Participant, such Participant's "401(k)
                 Plan Offset Amount" shall be the amount of the monthly annuity
                 payment to which such Participant would be entitled if the
                 balance (determined as of such Participant's Payment
                 Commencement Date) in such Participant's 401(k) Offset Account
                 (as defined herein below) were paid to such Participant in the
                 Normal Benefit Form commencing on his Normal Benefit Date. For
                 purposes of this paragraph (ii), a Participant's "401(k) Offset
                 Account"

<PAGE>
 
                 shall be a hypothetical account established and maintained with
                 respect to such Participant as follows: A Participant's 401(k)
                 Offset Account shall be established as of December 31, 1995,
                 and such 401(k) Offset Account shall have an initial balance
                 equal to the actual balance (if any) as of December 31, 1995,
                 in the account maintained under the 401(k) Plan for employer
                 contributions made with respect to such Participant (excluding
                 any employer contributions not currently includible in gross
                 income by reason of Code Section 402(e)(3)). Thereafter (A)
                 commencing with the 1996 calendar year and ending with the
                 calendar year in which such Participant incurs a Termination
                 (the "Termination Year"), the balance in such Participant's
                 401(k) Offset Account shall be increased as of the end of each
                 such calendar year (or, in the case of the Termination Year, as
                 of such Participant's Termination Date) by the amount of such
                 Participant's Hypothetical Employer Contribution (as defined in
                 paragraph (iii) below) for such calendar year and the actual
                 employer profit sharing contribution made for such calendar
                 year with respect to such Participant under the terms of the
                 401(k) Plan; and (B) commencing January 1, 1996, and ending on
                 such Participant's Payment Commencement Date, such
                 Participant's 401(k) Offset Account shall also be increased as
                 if the balance in such account (as increased from time to time
                 by the Hypothetical Employer Contributions Described in Clause
                 (A) above) were earning interest, compounded annually, (I) from
                 January 1, 1996, until such Participant's Termination Date, at
                 the Specified Rate applicable from time to time, and (II) from
                 such Participant's Termination Date until his Payment
                 Commencement Date, at the Specified Rate in effect as of such
                 Participant's Termination Date.

          (iii)  As used in paragraph (ii) above, "Hypothetical Employer
                 Contribution" means, with respect to any Participant, (A) for
                 any calendar year prior to such Participant's Termination Year
                 the maximum employer matching contribution that would have been
                 made for such calendar year with respect to such Participant
                 under the terms of the 401(k) Plan (disregarding the limits
                 imposed by reason of Code Section 401(m)) assuming such
                 Participant's before-tax deferral to the 401(k) Plan for such
                 calendar year is equal to his Hypothetical Participant Deferral
                 (as defined in paragraph (iv) below) with respect to such
                 calendar year; and (B) for

<PAGE>
 
                 such Participant's Termination Year, an amount equal to the
                 product obtained by multiplying (i) the Hypothetical Employer
                 Contribution determined with respect to such Participant for
                 the immediately preceding calendar year, by (ii) a fraction
                 having a numerator equal to the number of days in such
                 Termination Year prior to and including such Participant's
                 Termination Date, and having a denominator equal to 365.

          (iv)   For purposes of paragraph (iii) above, the "Hypothetical
                 Participant Deferral" applicable to any Participant for any
                 calendar year shall be the amount determined under the
                 following provisions, whichever is applicable:

                 (A)  If, with respect to any calendar year, the 401(k) Plan
                      administrative committee does not take any action, either
                      during or after the close of such year, to reduce the
                      level of Participant deferrals permitted to be made by any
                      401(k) Plan Participant for such year, then the
                      Hypothetical Participant Deferral with respect to any
                      Participant for such calendar year shall be the lesser of
                      (I) the maximum amount such Participant would be permitted
                      to contribute to the 401(k) Plan for such year under Code
                      Section 402(g), or (II) the maximum amount the Participant
                      would be permitted to contribute under the terms of the
                      401(k) Plan.

                 (B)  If, with respect to any calendar year, the 401(k) Plan
                      administrative committee takes action during and/or after
                      such year to reduce the level of Participant deferrals
                      permitted to be made by any 401(k) Plan Participant for
                      such year, then the Hypothetical Participant Deferral with
                      respect to any Participant for such year shall be the
                      lesser of (I) the maximum amount such Participant would be
                      permitted to contribute to the 401(k) Plan for such year
                      under Code Section 402(g), or (II) the product determined
                      by multiplying such Participant's compensation for such
                      year (as determined under the 401(k) Plan for anti-
                      discrimination testing purposes), by the maximum "actual
                      deferral percentage" for any highly compensated employee
                      for such year (as determined under Code Section
                      401(k)(3)(B) after giving effect to any corrections made
                      following the close of such year)

                      applicable to "highly-compensated employees" (as defined
                      in Code Section 414(q)).

   4.07   SPECIAL RULES FOR EARLY RETIREMENT.  In the case of any Participant 
          ----------------------------------
who incurs Early Retirement, such Participant's Monthly Annuity Amount shall be
determined as provided in Section 4.04 hereof, and then shall be reduced to
reflect the commencement of benefits on a date earlier than the Normal Benefit
Date as follows:

     (a)  If the Participant's Early Retirement commences on or after the first
          day of the month next following his sixty-second birthday, then the
          reduction shall be 0.25% for each full month by which the date of
          Early Retirement precedes the first day of the month next following
          his attainment of age 65.

     (b)  If the Participant's Early Retirement commences prior to the first day
          of the month next following his sixty-second birthday, then the
          reduction shall be 9.00% (representing the reduction from age 65 to
          age 62 described in paragraph (a) above) plus 0.50% for each full
          month by which the date of Early Retirement precedes the first day of
          the month next following his sixty-second birthday.

   4.08   TERMINATION OF PLAN PARTICIPATION.  In the event that the Board of
          ---------------------------------                                 
Directors determines that a Participant's employment performance is no longer at
a level which merits continued participation in the Plan, the Board may
terminate such Participant's participation in the Plan (without necessarily
terminating such Participant's employment) as of the date specified by the Board
(the "Participation Severance Date").  Accordingly, notwithstanding any other
provision of this Plan, the Supplemental Benefit payable to any Participant
whose Plan participation is terminated pursuant to this Section 4.08 shall be
calculated by taking into account, in determining the amount of such
Participant's Target Monthly Benefit and whether such Participant has met the
vesting requirement of Section 4.01 hereof, only the Service Years and
Compensation earned by such Participant as of his Participation Severance Date.
Such Supplemental Benefit shall be paid to the Participant pursuant to the
provisions of Section 4.03 herein.

   4.09   DISABILITY.  In the event that a Participant incurs a Termination as a
          ----------                                                            
result of such Participant's becoming Disabled, the Supplemental Benefit payable
to such Participant under this Plan shall be determined with regard to the
vesting requirement of Section 4.01 hereof assuming Service Years continue to
accrue until the earliest of (a) age 65, (b) return to Full-Time Employment, or
(c) the death of the Participant.  For purposes of this Plan, a Participant
shall be 

                                     IV-7
<PAGE>
 
deemed to be "Disabled" if and when, as a result of injury or sickness, such
Participant is permanently impaired to such an extent that he cannot perform,
and is not reasonably expected ever to be able to perform, each of the material
duties of his position of employment with the Sponsor or any Affiliated Company.
For the purpose of determining whether a Participant is Disabled, the Board may
require the Participant to submit to an examination by a competent physician or
medical clinic selected by the Board.

   4.10   CHANGE OF CONTROL.  Notwithstanding any other provision of this Plan,
          -----------------                                                    
upon a Change in Control, all Participants in the Plan shall be fully vested in
their Supplemental Benefits.  All Participants shall be entitled to the
Supplemental Benefit they would otherwise receive pursuant to this Article IV
hereof.  Upon and following a Change of Control, no Participant shall be removed
from the Plan, nor shall his benefit be terminated, modified, reduced or
eliminated without his express written consent.

   4.11   TERMINATION FOR CAUSE.  Notwithstanding any other provision of this 
          ---------------------
Plan except Section 4.10, a Participant who incurs a Termination for Cause prior
to a Change of Control shall not be entitled to a Supplemental Benefit,
regardless of Service Years, under this Plan.

                            DEATH OF A PARTICIPANT

   5.01   TERMINATION BY REASON OF DEATH.  In the event that a Participant 
          ------------------------------
incurs a Termination by reason of his death, (a) such Participant shall not be
entitled to receive a Supplemental Benefit under this Plan, and (b) if such
Participant has a Spouse at the time of his death, such Participant's Spouse
(the "Surviving Spouse") shall be entitled to receive a special benefit (a
"Death Benefit") at the times and in the amounts set forth in this Article V. No
Death Benefit shall be paid in respect of any Participant who does not have a
Spouse at the time of his death.

   5.02   FORM AND PAYMENT OF DEATH BENEFIT.  A Surviving Spouse who is 
          ---------------------------------
entitled to receive a Death Benefit pursuant to Section 5.01 hereof shall
receive such Death Benefit in the form of a Single Life Annuity which provides a
level monthly payment equal to the Monthly Death Benefit Amount specified in
Section 5.03 hereof. Except as otherwise provided hereinbelow, payment of a
Surviving Spouse's Death Benefit shall commence on the ninetieth (90th) day (the
"Death Benefit Commencement Date") after the Participant's death.

   5.03   MONTHLY DEATH BENEFIT AMOUNT.  The "Monthly Death Benefit Amount"
          ----------------------------                                     
applicable to any Surviving Spouse shall be an amount equal to the Monthly
Annuity Amount of the Supplemental Benefit that would have been payable to the
deceased Participant under Article IV hereof if such Participant had incurred a
Retirement on the day prior to his death, provided, however, that the
determination of such Monthly Annuity Amount shall take into account the
following assumptions and special rules:

   (a)    Such Monthly Annuity Amount shall be determined assuming the
          Participant would have received his Supplemental Benefit in the Normal
          Benefit Form, modified, if applicable, by the provisions of Section
          4.07 hereof.

   (b)    Such Monthly Annuity Amount shall be determined as if the Participant
          was 100% vested in the Supplemental Benefit.

   (c)    The Payment Commencement Date used in determining such Monthly Annuity
          Amount shall be deemed to be the Surviving Spouse's Death Benefit

                                      V-1
<PAGE>
 
          Commencement Date (disregarding any provision in Article IV to the
          contrary), and if the deceased Participant's death caused Early
          Retirement, the provisions of Section 4.07 hereof shall be applied in
          determining the deceased Participant's Monthly Annuity Amount after
          first determining the amount of the Defined Benefit Plan Offset Amount
          pursuant to subsection (c) above.

                            MISCELLANEOUS PROVISIONS

   6.01   PAYMENTS DURING INCAPACITY.  In the event a Participant (or 
          --------------------------
Beneficiary) is under mental or physical incapacity at the time of any payment
to be made to such Participant (or Beneficiary) pursuant to this Plan, any such
payment may be made to the conservator or other legally appointed personal
representative having authority over and responsibility for the person or estate
of such Participant (or Beneficiary), as the case may be, and for purposes of
such payment references in this Plan to the Participant (or Beneficiary) shall
mean and refer to such conservator or other personal representative, whichever
is applicable. In the absence of any lawfully appointed conservator or other
personal representative of the person or estate of the Participant (or
Beneficiary), any such payment may be made to any person or institution that has
apparent responsibility for the person and/or estate of the Participant (or
Beneficiary) as determined by the Committee. Any payment made in accordance with
the provisions of Section 6.01 to a person or institution other than the
Participant (or Beneficiary) shall be deemed for all purposes of this Plan as
the equivalent of a payment to such Participant (or Beneficiary), and the
Sponsor shall have no further obligation or responsibility with respect to such
payment.

   6.02   PROHIBITION AGAINST ASSIGNMENT.  Except as otherwise expressly 
          ------------------------------
provided in Section 6.01 hereof, the rights, interests and benefits of a
Participant under this Plan (a) may not be sold, assigned, transferred, pledged,
hypothecated, gifted, bequeathed or otherwise disposed of to any other party by
such Participant or any Beneficiary, executor, administrator, heir, distributee
or other person claiming under such Participant, and (b) shall not be subject to
execution, attachment or similar process. Any attempted sale, assignment,
transfer, pledge, hypothecation, gift, bequest or other disposition of such
rights, interests or benefits contrary to the foregoing provisions of this
Section 6.02 shall be null and void and without effect.

   6.03   BINDING EFFECT.  The Provisions of this Plan shall be binding upon the
          --------------                                                        
Sponsor, the Participants, all Affiliated Companies employing any Participants,
and any successor-in-interest to the Sponsor.

   6.04   NO TRANSFER OF INTEREST.  Benefits under this Plan shall be payable
          -----------------------                                            
solely from the general assets of the Sponsor (and, with respect to any
Participant who is an employee of an Affiliated Company, also from the general
assets of such Affiliated Company), and no person 

                                     VI-1
<PAGE>
 
shall be entitled to look to any other source for payment of such benefits. The
Sponsor (and, if applicable, any Affiliated Company) shall have and possess all
title to, and beneficial interest in, any and all funds or reserves maintained
or held by the Sponsor (or such Affiliated Company) on account of any obligation
to pay benefits as required under this Plan, whether or not earmarked as a fund
or reserve for such purpose; any such funds, other property or reserves shall be
subject to the claims of the creditors of the Sponsor (or such Affiliated
Company), and the provisions of this Plan are not intended to create, and shall
not be interpreted as vesting, in any Participant, Beneficiary or other person,
any right to or beneficial interest in any such funds, other property or
reserves. Nothing in this Section 6.04 shall be construed or interpreted as
prohibiting or restricting the establishment of a grantor trust within the
meaning of Code Section 671 which is unfunded for purposes of Sections 201(2),
301(a)(3), and 401(a)(l) of ERISA, from which benefits under this Plan may be
payable.

   6.05   AMENDMENT OR TERMINATION OF THE PLAN.  The Board of Directors may 
          ------------------------------------
amend this Plan from time to time in any respect that it deems appropriate or
desirable, and the Board may terminate this Plan at any time; provided, however,
that any such amendment or termination may not, without the written consent of a
Participant, eliminate or reduce the Supplemental Benefit that has accrued with
respect to such Participant as of the effective date of such amendment or
termination.  For purposes of this Section 6.05, the Supplemental Benefit that
has accrued with respect to any Participant as of the date of any amendment of
termination of the Plan shall be deemed to be the Supplemental Benefit to which
such Participant would be entitled pursuant to Article IV hereof if such
Participant incurred Retirement immediately prior to such Plan amendment or Plan
termination.

   6.06   NO RIGHT TO EMPLOYMENT.  This Plan is voluntary on the part of the
          ----------------------                                            
Sponsor and its Affiliated Companies, and the Plan shall not be deemed to
constitute an employment contract between any Participant and the Sponsor or any
Affiliated Company, nor shall the adoption or existence of the Plan or any
provision contained in the Plan be deemed to be a required condition of the
employment of any Participant.  Nothing contained in this Plan shall be deemed
to give any Participant the right to continued employment with the Sponsor or
any Affiliated Company, and the Sponsor and its Affiliated Companies may
terminate any Participant at any time, in which case the Participant's rights
arising under this Plan shall be only those expressly provided under the terms
of this Plan.
