        applicable,  the  probability  of  surviving  to  receive  such  benefit
        ("Mortality") and the time value of money ("Interest").  The calculation
        of actuarial present values shall be based on the actuarial  assumptions
        as set forth in Appendix A to this Plan.

1.2     "Actuary" shall mean the firm employing an "enrolled actuary" as defined
        in Section 7701(a)(35) of the Code appointed by the Administrator.

        completed  consecutive  calendar years of service,  his Average  Monthly

        but  including any Employee  deferrals  pursuant to Code Sections 125 or
        401(k).  Compensation  shall not exceed the  maximum  amount that may be
        taken into account under Code Section  401(a)(17),  adjusted as provided

        compensation  prior  to  the  application  of  this  limitation,  or the

                        otherwise  payable to the Participant shall be suspended

                        rules  relating to such a  suspension  of  benefits  and
                        their  subsequent   resumption  are  described  in  this
                        Section.

                (ii)    The Committee  shall notify the  Participant by personal
                        delivery  or first class mail of the  suspension  of his

                        employment  relationship which such Participant has with
                        the Company.  The Committee  shall have the right to use
                        all  reasonable   efforts  to  determine   whether  such
                        employment   constitutes   qualified   reemployment   or
                        qualified employment.  The Committee shall also have the
                        right to require the Participant to provide  information

                        to  make  a   determination   as  to  whether   specific
                        contemplated     employment     constitutes    qualified
                        reemployment  or  qualified  employment.  The  Committee
                        shall respond to such request in writing  within 60 days
                        of the Committee's receipt of the request.

                (v)     Subject to Sections 8.3 and 8.8, benefit payments to the
                        Participant  will resume (or commence) no later than the
                        first  day of the third  calendar  month  following  the
                        month in which his qualified  reemployment  or qualified
                        employment  ceases  or, if  later,  the first day of the
                        calendar month following receipt by the Committee of the
                        Participant's notice that his qualified  reemployment or
                        qualified  employment has ceased. The initial resumption
                        payment shall include  payment for the current month and
                        for all previous  calendar months since the cessation of
                        the Participant's qualified employment or reemployment.

                (vi)    The Committee shall offset resumed benefits by an amount
                        equal to any benefits which were paid to the Participant
                        with   respect  to  a   calendar   month  in  which  the
                        Participant  was engaged in  qualified  reemployment  or
                        qualified employment. However, the offset to any monthly
                        benefit,  other  than the  initial  resumption  payment,
                        shall  not  exceed  twenty-five  percent  (25%)  of such
                        monthly  benefit.  Any remaining offset shall be applied
                        to benefits payable in subsequent months.

                Company  under any  circumstances  other  than as  described  in
                Subsection   (a),   the  benefits   otherwise   payable  to  the
                Participant  shall be continued during such period of employment
                or reemployment.

                Service (not including Hours of Service  credited as a result of
                back pay) during a calendar  month.  Notwithstanding  the above,
                for Participants that attain age 70 1/2 in calendar years before
                January  1,  2003,  qualified  reemployment  shall  not  include
                employment on or after the April 1st following the calendar year
                in  which  the  Participant  attains  age 70 1/2.  In  addition,
                effective  January 1,  2002,  qualified  reemployment  shall not
                include  employment with respect to a Participant  that makes an
                election to commence benefits under Section 8.3(b).

        (d)     Qualified  employment  shall mean the continued  employment of a
                Participant  after his Normal Retirement Date in such a capacity
                that (and provided that) the Participant receives or is entitled
                to be paid for at least 40 Hours of Service (not including Hours
                of Service  credited  as a result of back pay) during a calendar
                month.  Notwithstanding  the above, for Participants that attain
                age 70 1/2 in calendar years before  January 1, 2003,  qualified
                employment  shall not include  employment  on or after the April

                employment  shall  not  include  employment  with  respect  to a
                Participant  that makes an election to commence  benefits  under
                Section 8.3(b).

                          -----------------------------



7.1     Pre-Retirement Survivor Death Benefit
        ---------------------------------------

        In the event of a death of a Participant who (a) has a Vested  Interest,
        and (b) has not yet had an  Annuity  Starting  Date,  the  Participant's
        designated  beneficiary  shall receive a  Pre-Retirement  Survivor Death
        Benefit.   For  purposes  of  this  Article,  a  married   Participant's
        designated  beneficiary shall be the Participant's Spouse. For Employees
        who are hired by the Company or a  Subsidiary  on or after  September 1,
        2001,  the  provisions  of  this  Section  7.1  will  apply  only if the
        Participant is married on his or her date of death.

7.2     Amount and Form of Pre-Retirement Survivor Death Benefit
        --------------------------------------------------------

        Subject to the  following,  the  Participant's  Pre-Retirement  Survivor
        Death  Benefit shall be paid to the  Participant's  Spouse or designated
        beneficiary  in the form of an annuity for the  Spouse's  or  designated
        beneficiary's life. The amount of the monthly annuity shall be such that
        the present value of the Pre-Retirement  Survivor Death Benefit shall be
        equal to the present value of the deceased  Participant's vested Accrued
        Benefit  on  his  date  of  death.  Notwithstanding  the  above,  if the
        Participant is married,  the present value of the monthly  annuity shall
        not be  less  than  the  present  value  of a  Qualified  Pre-Retirement
        Survivor  Annuity.  If  the  Actuarial  Equivalent  present  value  of a
        Participant's  Pre-Retirement  Survivor  Death Benefit as of the Annuity
        Starting Date does not exceed $5,000,  the method of distribution to the
        Participant's Spouse or designated beneficiary shall be as a single cash
        distribution  which  is  the  Actuarial   Equivalent  of  the  Qualified
        Pre-Retirement Survivor Annuity.

7.3     Timing of Distribution
        ----------------------

        Distribution  of a Participant's  Pre-Retirement  Survivor Death Benefit
        shall  commence as of the  Annuity  Starting  Date of the  Participant's
        Spouse or  designated  beneficiary.  The  Annuity  Starting  Date of the
        Participant's  Spouse or  designated  beneficiary  shall be the earliest
        date which the  Participant  could have begun to receive  benefits if he
        had survived  (the first day of the month  following  the  Participant's
        death if the  Participant  had been eligible at the time of his death to
        begin  receiving  benefits).  Notwithstanding  the  above,  (1)  if  the
        Participant's  Pre-Retirement  Survivor  Death Benefit is not payable in
        the form of a Qualified  Pre-Retirement Death Benefit,  then the Annuity
        Starting Date of the Participant's  designated  beneficiary shall be the
        first  day  of  the  month   coincident   with  or  next  following  the
        Participant's date of death, and (2) if the Actuarial Equivalent present
        value of his  Pre-Retirement  Survivor  Death  Benefit  does not  exceed
        $5,000,  the  Annuity  Starting  Date  of the  Participant's  designated
        beneficiary  shall be the first day of the month coincident with or next
        following the Participant's death.

7.4     Required Distribution
        ---------------------

        If a Participant's  Pre-Retirement Survivor Death Benefit is paid in the
        form of a single cash payment, the Participant's  entire  Pre-Retirement
        Survivor   Death  Benefit  shall  be   distributed   to  his  designated
        beneficiary  within  five  years  of  the  Participant's   death.  If  a
        Participant's  Pre-Retirement  Survivor  Death Benefit is distributed in
        the form of an annuity,  distribution  shall commence by the December 31
        of the year after the year of the  Participant's  death or, if later, in
        the  case of a  married  Participant,  the  December  31 of the year the
        Participant would have attained age 70 1/2. Such Pre-Retirement Survivor

                                  DISTRIBUTION
                                  ------------


8.1     Optional  Forms of  Benefits.  The  Participant  may  elect,  subject to
        ----------------------------
        Section 8.7, to receive  distribution of his Retirement  Benefit (if the
        Actuarial   Equivalent   present   value  of  such  benefit  as  of  the
        Participant's  Annuity  Starting  Date  or at  the  time  of  any  prior
        distribution is in excess of $5,000) by one of the following methods:

        (a)     a Single  Life  Annuity - an annuity  payable  in equal  monthly
                installments to the retired Participant for his life; or

        (b)     a Qualified  Joint and Survivor  Annuity - an annuity payable in
                monthly  installments  to the  Participant for his life and with
                fifty  percent  (50%) of the amount of such monthly  installment
                payable after his death of the Participant to the Spouse of such
                Participant,  if then living,  for the life of such Spouse.  The
                benefit payable to the Participant and  co-pensioner  under this
                form of payment shall be the Actuarial  Equivalent of the Single
                Life form of payment; or

        (c)     a Single  Life  Annuity  with a 60,  120,  or 180  month  period
                certain   feature  -  an  annuity   payable  in  equal   monthly
                installments  to the retired  Participant for his life, with 60,
                120, or 180 monthly  payments  guaranteed.  The benefits payable
                shall be the  Actuarial  Equivalent  of the Single  Life form of
                payment; or

        (d)     a Joint and  Survivor  Annuity  for the life of the  Participant
                with a survivor annuity for the life of the Participant's  named
                co-pensioner  equal to 50 percent  or 100  percent of the amount
                payable  to  the   Participant.   The  benefit  payable  to  the
                Participant and co-pensioner under this form of payment shall be
                the Actuarial Equivalent of the Single Life form of payment.

8.2     Small Benefit Payments. If the Actuarial Equivalent present value of the
        ----------------------
        Retirement Benefit is less than $5,000,  such benefit shall be paid in a
        single lump sum payment.

        Notwithstanding the above,  effective for distributions  occurring on or
        after  March  22,  1999,   if  a   Participant   has  begun  to  receive
        distributions  pursuant  to an optional  form of benefit  under which at
        least one scheduled periodic  distribution has not yet been made, and if
        the present value of the Participant's  benefit at the time of the first
        distribution  exceeded  the  cash-out  limit set forth  above,  then the
        present  value of the  Participant's  benefit is deemed to  continue  to
        exceed such cash-out limit.



                                      -24-

        ----------------------------------------------

        (a)     Distribution  of  a  Participant's   Retirement   Benefit  shall
                commence  as of  his  Annuity  Starting  Date.  A  Participant's
                Annuity Starting Date shall be the earliest of (1) the first day
                of the month  coincident  with or next  following the day of the
                Participant's  Retirement,  (2)  the  first  day  of  the  month
                coincident  with or next following the day of the  Participant's
                Separation  from  Service  if  as of  that  date  the  Actuarial
                Equivalent  present value of his Vested Interest does not exceed
                $5,000,  (3) the first day of the month  coincident with or next
                following  the  Participant's  Normal  Retirement  Date  if  the
                Participant  has a Separation  from Service  prior to that time,
                unless the  Participant  elects under Section 8.4 to commence to
                receive  distribution  prior to his Normal  Retirement Date, and
                (4) effective for all  Participants  (except  Participants  that
                attained age 70 1/2after  January 1, 1988 and before  January 1,
                2003, or  Participants  that are Five Percent  Owners during the
                Plan Year ending with or within the calendar  year in which they
                attain age 70 1/2or any subsequent Plan Year),  the first day of
                April  immediately  following  the  calendar  year in which  the
                Participant  retires or  attains  age 70 1/2,  whichever  occurs
                later. For Participants that attained age 70 1/2after January 1,
                1988 and prior to January 1, 2003,  and for Five Percent  Owners
                as described above, the required beginning date of Plan benefits
                is April 1 of the calendar  year  following the calendar year in
                which the  Participant  attains age 70 1/2. In no event,  unless
                the  Participant  elects  otherwise,  shall  distribution  of  a
                Participant's  Vested Interest commence later than 60 days after
                the latest of the last day of the Plan Year in which  occurs (i)
                the  Participant's   Retirement,   and  (ii)  the  Participant's
                attainment of age 65.

        (b)     Notwithstanding   the  above,   effective  January  1,  2002,  a
                Participant  that has completed twenty years of Credited Service
                and attained age 70 who is an active Employee may elect (subject
                to the minimum distribution  requirements of Sections 8.3(a) and
                8.8) to  commence  benefits  as of the  first  day of the  month
                following  attainment  of age 70 or as of the  first  day of any
                month thereafter  while an active  Employee.  The calculation of
                the benefit payable to such a Participant that makes an election
                under this  subsection  shall be made in accordance with Section
                5.6.  The first date for which  benefits  are  payable due to an
                election   under  this   subsection   shall  be  considered  the
                Participant's Annuity Starting Date.

        Starting Date, may elect to have distribution of his Retirement  Benefit
        commence before his Normal Retirement Date. In that event,  distribution
        shall commence as of the first day of any month  following the election,
        but not prior to a Participant's Early Retirement Date.

8.5     Qualified Joint and Survivor Annuity for Married Participants
        -------------------------------------------------------------

        (a)     Subject to subsection  (b), a Participant  who is married on his
                Annuity   Starting  Date  shall  receive   distribution  of  his
                Retirement Benefit in the form of a Qualified Joint and Survivor
                Annuity,  unless the Participant has previously waived his right
                to receive  benefits  in this form.  The waiver must be executed
                and consented to by the Participant's  Spouse in accordance with
                Section  8.7.  Both the  Participant's  waiver and the  Spouse's
                consent must state the particular optional form of benefit to be
                distributed.  Alternatively, the Spouse's consent may permit the
                Participant  to elect any  optional  form of  benefit  available
                under the Plan. Such a general consent must acknowledge that the
                Spouse has voluntarily relinquished rights to limit consent to a
                specific form of benefit. A Participant's  waiver of a Qualified
                Joint and Survivor Annuity under this Section 8.5 may be revoked
                at any time before the Participant's  Annuity Starting Date and,
                once  revoked,  may be made again  before that date.  A Spouse's
                consent  to the  waiver  once  given may be  revoked  before the
                Annuity Starting Date.

        (b)     In the case of a  Participant  (i) who is married  for less than
                one  year  on  his  Annuity   Starting   Date,   (ii)   receives
                distribution  of  his  Retirement  Benefit  in  the  form  of  a
                Qualified  Joint and Survivor  Annuity and (iii) does not remain
                married to his Spouse for at least one year,  such Spouse  shall
                lose all survivor rights. In such event the Participant shall be
                entitled to receive  distribution  of his Retirement  Benefit in
                any other form under Section 8.1.

        Within the period  beginning no earlier than 90 days,  and no later than
        30  days   before   the   Participant's   Annuity   Starting   Date  the
        Administrative Committee shall provide each Participant with a notice of
        the  Participant's  right  to  elect  to  waive  his  right  to  receive

        dollars per annuity payment), (b) the requirement that the Participant's
        Spouse must consent to the election in accordance  with Section 8.7, (c)

        ----------------
        Survivor  Annuity  described  in Section  8.6 shall be valid only if the
        Participant's  Spouse  executes  a  written  consent  to  that  election

8.8     Minimum Distribution Requirements.
        ----------------------------------

        (a)     Notwithstanding any provision of this Plan to the contrary,  all

                Section 401(a)(9) of the Code and the regulations promulgated by
                the Secretary of the Treasury thereunder.

        (b)     In the case of a Participant  who is a Five Percent Owner,  or a
                Participant  that attains age 70 1/2prior to January 1, 2003, or
                a Participant that makes an election to commence  benefits under
                Section 8.3(b), if such a Participant  remains an Employee after
                attainment  of age 70 1/2(or age 70 for a  Participant  electing
                under Section  8.3(b)) and has  commenced to receive  Retirement
                Benefits  from  the  Plan,  such  Participant  shall  have  such
                benefits  increased as of the first day of each calendar year to
                reflect any additional  Credited Service accrued during the Plan
                Year ending  immediately  before the first day of that  calendar
                year. If a  Participant  who is not a Five Percent Owner attains
                age 70  1/2after  January 1,  2003,  the  Participant's  accrued
                benefit  shall  be  actuarially  increased  in  accordance  with
                Appendix A to take into  account  the period  after age 70 1/2in
                which the  Participant  is not  receiving  any benefits from the
                Plan.  The actuarial  increase  shall be provided for the period
                starting on April 1  following  the  calendar  year in which the
                employee  attains age 70 1/2. The actuarial  increase  described
                above will be  provided  even  during  the  period  when a valid
                benefit suspension is in place under ERISA Section 203(a)(3)(B).

        (c)     If a Participant dies after the date his Retirement  Benefit has
                commenced,  the remaining portion,  if any, of the Participant's
                benefit shall be distributed to the Participant's beneficiary at
                least as  rapidly as it would  have been  distributed  under the
                method of distribution in effect on the day of the Participant's
                death.

                                      -27-



        (d)     If a Participant's Retirement Benefit is distributed in the form
                of an  annuity  other  than  an  annuity  for  the  life  of the
                Participant or an annuity for the joint lives of the Participant
                and  the  Participant's   Spouse  or  in  installments  and  the
                Participant's   Beneficiary  is  other  than  the  Participant's
                Spouse,  the distribution must satisfy the minimum  distribution
                incidental benefit  requirements under Section  1.401(a)(9)-2 of
                the Income Tax Regulations.

        (e)     With  respect to  distributions  under the Plan made in calendar
                years beginning on or after January 1, 2001, the Plan will apply
                the minimum  distribution  requirements of section  401(a)(9) of
                the Internal  Revenue Code in  accordance  with the  regulations
                under  section  401(a)(9)  that were  proposed in January  2001,
                notwithstanding any provision of the Plan to the contrary.  This
                amendment  shall  continue  in effect  until the end of the last
                calendar  year  beginning  before  the  effective  date of final
                regulations  under  Code  section  409(a)(9)  or such other date
                specified in guidance published by the Internal Revenue Service.

        (a)     This Section applies to  distributions  made on or after January
                1,  1993.  Notwithstanding  any  provision  of the  Plan  to the
                contrary that would  otherwise  limit a  distributee's  election
                under this Section,  a distributee may elect, at the time and in
                the manner  prescribed  by the Plan  Administrator,  to have any

                eligible  retirement  plan  specified  by the  distributee  in a
                direct rollover.

        (b)     For purposes of this  Section the  following  definitions  shall
                apply:

                (i)     An eligible rollover distribution is any distribution of

                        distributee,    except   that   an   eligible   rollover
                        distribution does not include:  any distribution that is
                        one of a series of substantially equal periodic payments
                        (not less  frequently  than  annually) made for the life
                        (or life  expectancy)  of the  distributee  or the joint
                        lives (or joint life  expectancies)  of the  distributee
                        and the distributee's  designated beneficiary,  or for a
                        specified  period of ten years or more; any distribution
                        to the extent such  distribution  is required under Code
                        Section  401(a)(9);  and the portion of any distribution
                        that  is not  includible  in  gross  income  (determined
                        without  regard  to the  exclusion  for  net  unrealized
                        appreciation with respect to employer securities).

                (ii)    An eligible retirement plan is an individual  retirement

                        accepts    the    distributee's     eligible    rollover
                        distribution.  However,  in  the  case  of  an  eligible

                                      -28-



                        rollover   distribution  to  the  surviving  Spouse,  an
                        eligible  retirement  plan is an  individual  retirement
                        account or individual retirement annuity.

                (iii)   A distributee  includes an Employee or former  Employee.
                        In  addition,   the  Employee's  or  former   Employee's
                        surviving Spouse and the Employee's or former Employee's
                        Spouse or former Spouse who is the alternate payee under

                (iv)    A  direct  rollover  is a  payment  by the  plan  to the
                        eligible retirement plan specified by the distributee.

8.10    Payments To Incompetents
        ------------------------

        If the Committee shall find that any person to whom a benefit is payable
        from the Trust Fund is unable to care for his affairs because of illness
        or  accident,  or is a minor,  any  payment  due  (unless a prior  claim
        therefore shall have been made by a duly appointed  guardian,  committee
        or other legal  representative)  may be paid to the Spouse,  a child,  a
        parent, or a brother or sister, or to any person deemed by the Committee
        to have incurred expense for such person otherwise  entitled to payment.
        Any such payment  shall be a complete  discharge of any liability of the
        Company,  the Administrator,  the Committee,  the Trustee,  and the Fund
        therefore.

8.11    Lost  Participant.  Neither the  Administrator  nor the Trustee shall be
        -----------------
        obligated to search for or ascertain the  whereabouts of any Participant
        or  Beneficiary  (other  than to  write to the  Participant  at his last
        mailing  address  shown  in  the  Plan  Administrator's  records).  If a
        Participant  or  Beneficiary   cannot  be  located,   the  Participant's
        Retirement  Benefit or Pre-Retirement  Death Benefit shall be forfeited,
        but shall be reinstated  (without  interest) upon the  Participant's  or
        Beneficiary's claim for the benefit.

8.12    Deemed Cashouts
        ---------------

        Notwithstanding  any other provision  contained herein, if a Participant
        separates from service and the Actuarial Equivalent present value of his
        vested Accrued Monthly Pension is zero, the Participant  shall be deemed
        to have received a distribution of his vested Accrued Monthly Pension.

        (a)     Annual Benefit - shall mean a benefit which is payable  annually
                in the  form  of a  straight  life  annuity  with  no  ancillary
                benefits.

        (b)     Compensation  - shall mean  annual  compensation,  as defined in
                Regulation   1.415(2)(d)(l)  of  the  Code,  and  effective  for

                402(g)(3) and (ii) any amount which is  contributed  or deferred
                by the  Company  at the  election  of an  Employee  which is not
                includible  in gross  income by reason of Code  Section  125, or
                effective January 1, 2001, Code Section 132(f).

        (c)     Defined  Benefit Plan Fraction - for any limitation  year ending
                before the 2000 limitation year is a fraction:

                (i)     the numerator of which is the Projected  Annual  Benefit

                        (determined as of the close of the year), and

                (ii)    the denominator of which is the lesser of:

                        (1)     1.25  multiplied  by $90,000 (or the  applicable
                                dollar  limitation  under Section  415(d) of the

                        (2)     1.4   multiplied   by   the   average   of   the
                                Participant's   total  Compensation  during  the
                                three  consecutive  years in which he earned the
                                greatest amount of total  Compensation  from the
                                Company.

        (d)     Defined  Contribution  Plan Fraction - for any  limitation  year
                ending on or before the 2000 limitation year is a fraction:

                (i)     the numerator of which is the sum of annual additions to
                        the    Participant's    accounts   under   the   Defined
                        Contribution Plan as of the close of the year, and

                (ii)    the denominator of which is the sum of the lesser of the
                        following  amounts for such year and for each prior year
                        of service with the Company;


                                      -30-



                        (1)     1.4  multiplied by the amount  determined  under
                                Section 415(c)(l)(B) of the Code, or

                        (2)     1.25  multiplied  by $30,000 (or the  applicable
                                dollar limitation under Section  415(c)(1)(A) of
                                the Code).

                For limitation  years ending before the 2000 limitation year, in
                the case of a  Participant  with  respect to whom the sum of his
                Defined  Benefit  Plan  Fraction and Defined  Contribution  Plan
                Fraction exceeds 1.0 as of either (or both) December 31, 1982 or
                December 31, 1986  (computed as if the provisions of Section 415
                of  the  Code,   as   amended  by  the  Tax  Equity  and  Fiscal
                Responsibility  Act of  1982  or the  Tax  Reform  Act of  1986,
                respectively,  were in effect on the  applicable of those dates)
                the numerator of the  Participant's  Defined  Contribution  Plan
                Fraction shall be reduced so that the sum of those  fractions as
                of the applicable date does not exceed 1.0.

        (e)     Projected  Annual  Benefit - shall  mean the  annual  benefit to
                which a  Participant  would be  entitled  under the terms of all
                Defined Benefit Plans if he had continued  employment  until his
                normal  retirement date under such plans and if his compensation
                for the purpose of such plans had continued at the same rate.

9.2     Maximum Retirement Benefit. Notwithstanding any other provisions of this
        --------------------------
        Plan the Maximum Retirement Benefit shall be:

        (a)     Subject to Sections 9.2(b), (c), and (d), the Retirement Benefit
                of a  Participant  shall be reduced to the extent that it (plus,
                if  applicable,  the aggregate  retirement  benefit to which the
                Participant is entitled under all other Defined Benefit Plans in
                which he or she was a  participant)  exceeds  the  lesser of (1)
                $90,000 (or such higher amount as may be permitted under Section
                415 (d) of the Code to reflect  increases in the cost of living,
                and  (2)  100  percent  of  the  Participant's   average  annual
                compensation  during the three  consecutive  Plan Years in which
                the Participant received the greatest aggregate amount of annual
                compensation.  No reduction shall be required under this Section
                9.2(a) in the case of a Participant who never  participated in a
                defined  contribution  plan  if  the  Participant's   Retirement
                Benefit  (plus,  if  applicable,  the  Participant's  retirement
                benefit under all other Defined  Benefit  Plans) does not exceed
                $10,000.

        (b)     The  following   adjustments  shall  be  made  in  applying  the
                limitations of Sections 9.2(a) and 9.4.

                (i)     If a Participant's  Retirement  Benefit (or a retirement
                        benefit to which the  Participant  is entitled under any
                        other  Defined  Benefit Plan) is payable in a form other
                        than an Annual Benefit,  the Retirement Benefit shall be
                        adjusted so that it is the  Actuarial  Equivalent  of an
                        Annual  Benefit,  except that the following shall not be
                        taken into account:  (A) any  ancillary  benefit that is


                                      -31-



                        not related to  retirement  income  benefits and (B) the
                        survivor  annuity  provided  under  the  portion  of any
                        annuity that  constitutes a Qualified Joint and Survivor
                        Annuity (as defined in Section 417(b) of the Code).

                        Effective  September 1, 1995,  for purposes of adjusting
                        any  benefit  for any form of  payment  subject  to Code
                        Section  417(e)(3),  the interest rate assumption  shall
                        not be less than the greater of the applicable  interest
                        rate described in Appendix A(2)(b) or the rate described
                        in Appendix A(1)(a).

                (ii)    The dollar  limitation  set forth in  Section  9.2(a)(i)
                        shall be adjusted as follows:

                        (1)     If distribution  of a  Participant's  Retirement
                                Benefit begins before the  Participant's  Social
                                Security  retirement  age as  defined in Section
                                415(b)(8) of the Internal Revenue Code but on or
                                after  the  Participant's  attainment  of age 62
                                then the  limitation  shall be reduced by 5/9 of
                                one  percent for each of the first 36 months and
                                5/12 of one percent  for each of the  additional
                                months (up to 24  months),  if any, by which the
                                benefits commenced before the month in which the
                                Participant  attains his or her Social  Security
                                retirement age.

                        (2)     If   the   distribution   of   a   Participant's
                                Retirement  Benefit  begins  before  his  or her
                                attainment of age 62 then the  limitation  shall
                                be reduced by (A) reducing the limitation to the
                                applicable  limit for benefits payable at age 62
                                in accordance  with  paragraph (i); and (B) then
                                determining  the  Actuarial  Equivalent  of that
                                amount at the Participant's age at the time that
                                the benefit commences.

                        (3)     If distribution  of a  Participant's  Retirement
                                Benefit  begins after the  Participant's  Social
                                Security retirement age, the limitation shall be
                                increased  (in   accordance   with   regulations
                                promulgated by the Secretary of the Treasury) so
                                that it equals the  amount of an Annual  Benefit
                                beginning  at  the  time   distribution  of  the
                                Participant's  Retirement Benefit begins,  which
                                is the Actuarial Equivalent of an Annual Benefit
                                equal  to the  dollar  limitation  set  forth in
                                Section 9.2(a)(1) beginning at the Participant's
                                Social Security retirement age.

                (iii)   In the case of a Participant with less than ten years of
                        participation in the Plan or less than ten (10) years of
                        Credited Service:

                        (1)     the  dollar  limitation  set  forth  in  Section
                                9.2(a)(i)  shall be multiplied by a fraction the
                                numerator  of which is the  aggregate  number of

                                      -32-



                                the Participant's  years of participation in the
                                Plan at the time the  determination  is made and
                                the denominator of which is ten, and

                        (2)     the  percentage  limitation set forth in Section
                                9.2(a)(2)  and  the  $10,000   minimum   benefit
                                referred  to in the  last  sentence  of  Section
                                9.2(a)  shall be  multiplied  by a fraction  the
                                numerator  of which is the  aggregate  number of
                                the years of the Participant's  Years of Service
                                at the  time the  determination  is made and the
                                denominator of which is ten.

                (iv)    For purposes of adjusting the  Participant's  retirement
                        benefit under Section 9.2(b)(i) or the dollar limitation
                        under Section  9.2(b)(ii),  the interest rate assumption
                        shall be that set  forth in the  Appendix  to this  Plan
                        subject to the  limitations on interest rates of Section
                        415(b)(2)(E)  of the Code,  and the mortality  decrement
                        shall be ignored to the extent  that a  forfeiture  does
                        not occur at death.

        (c)     The  Retirement  Benefit of a Participant  who was a Participant
                before  January  1, 1987  shall not be  reduced  under any other
                provisions  of this  Section  9.2 to the extent that it does not
                exceed the Participant's  Retirement  Benefit accrued as of that
                date and  determined  in  accordance  with the  requirements  of
                Section  415 of the Code in  effect  on that  date  and  without
                regard  to  amendments  to  the  Plan  after  May 5,  1986.  The
                Retirement Benefit of a Participant who was a Participant before
                January 1, 1983 shall be similarly protected.

        (d)     If a Participant  is a participant  in any Defined  Contribution
                Plan for  limitation  years  ending  before the 2000  limitation
                year, the Participant's  Retirement  Benefit shall be reduced to
                the extent that it causes the sum of the  Participant's  Defined
                Benefit Plan Fraction and the Participant's Defined Contribution
                Plan Fraction to exceed 1.0 for any Plan Year.

        (e)     If Section 415 of the Code is amended, or if new regulations are
                promulgated by the Secretary of Treasury, the restrictions under
                this  Section  9.2  shall be  correspondingly  modified  without
                formal amendment to this Plan.

9.4     Restrictions on 25 Highest Paid Employees
        -----------------------------------------

        (a)     Benefits  distributed to any of the twenty-five (25) most highly
                compensated  active and highly compensated former employees with
                the  greatest  compensation  in the  current  or prior  year are
                restricted such that the monthly payments are no greater than an
                amount equal to the monthly payment that would be made on behalf
                of such  individual  under a straight  life  annuity that is the
                Actuarial  Equivalent  of the  sum of the  individual's  Accrued
                Monthly Pension,  the individual's other benefits under the Plan
                (other than a social security  supplement  within the meaning of
                Regulation 1.411(a)-7(c)(4)(ii)),  and the amount the individual
                is  entitled  to  receive  under a social  security  supplement.
                However, the limitation of this Section 9.4 shall not apply if:

                (i)     after payment of the benefit to an individual  described
                        above,  the value of Plan  assets  equals or exceeds 110
                        percent of the value of current liabilities,  as defined
                        in Code Section 412(1)(7);

                (ii)    the value of the benefits  payable  under the Plan to an
                        individual described above is not less than 1 percent of
                        the value of current liabilities before distribution; or

                (iii)   the value of the benefits  payable  under the Plan to an
                        individual described above does not exceed $5,000.

        (b)     For  purposes of this  Section,  benefit  includes  any periodic
                income,  any withdrawal values payable to a living  Participant,
                and any death  benefits  not  provided  for by  insurance on the
                individual's life.

        (c)     An individual's  otherwise restricted benefit may be distributed
                in full to the affected  individual  if, prior to receipt of the
                restricted   amount,   the  individual  enters  into  a  written
                agreement with the Administrator to secure repayment to the Plan
                of the restricted amount. The restricted amount is the excess of
                the amounts  distributed  to the  individual  (accumulated  with
                reasonable  interest)  over the  amounts  that  could  have been
                distributed  to the  individual  under the straight life annuity
                described  above  (accumulated  with reasonable  interest).  The
                individual may secure  repayment of the  restricted  amount upon
                distribution by:

                (i)     entering into an agreement for promptly  depositing into
                        escrow with an acceptable depositary,  property having a
                        fair  market  value equal to at least 125 percent of the
                        restricted amount;

                (ii)    providing a bank letter of credit in an amount  equal to
                        at least 100 percent of the restricted amount; or

                                      -34-



                (iii)   posting  a bond  equal to at least  100  percent  of the
                        restricted  amount.  The bond  must be  furnished  by an
                        insurance  company,  bonding company or other surety for
                        federal bonds.

        (d)     The escrow  agreement  may permit an individual to withdraw from
                escrow  amounts  in  excess  of 125  percent  of the  restricted
                amount. If the market value of the property in an escrow account
                falls below 110 percent of the remaining  restricted amount, the
                individual must deposit  additional  property to bring the value
                of the property held by the  depositary up to 125 percent of the
                restricted  amount.  The escrow arrangement may provide that the
                individual has the right to receive any income from the property
                placed in escrow,  subject  to the  individual's  obligation  to
                deposit  additional  property,  as set  forth  in the  preceding
                sentence.

        (e)     A surety or bank may release any  liability  on a bond or letter
                of credit in excess of 100 percent of the restricted amount.

        (f)     If the Administrator certifies to the depositary, surety or bank
                that the  individual (or the  individual's  estate) is no longer
                obligated  to repay any  restricted  amount,  a  depositary  may
                deliver  to the  individual  any  property  held under an escrow
                arrangement,  and a surety or bank may release any  liability or
                an individual's bond or letter of credit.

        (g)     Notwithstanding  the  foregoing,  with  respect  to  Plan  Years
                beginning prior to January 1, 1989, compliance with the Plan and
                Regulations then in effect shall be deemed  compliance with this
                Section 9.4.

        Fund shall be used for or diverted to  purposes  other than  exclusively
        for the  benefit  of such  Participants,  former  Employees,  and  their
        eligible  survivors and for necessary  administrative  costs;  provided,

        attributable  to  contributions  by  the  Company  shall  revert  to the
        Company;  and further  provided that, in the case of a contribution  (a)
        made by the  Company  as a  mistake  of  fact,  or (b)  for  which a tax
        deduction is  disallowed,  in whole or in part, by the Internal  Revenue
        Service, the Company shall be entitled to a refund of said contributions
        (i) within one year after payment of a contribution is made as a mistake
        of fact,  or (ii) within one year after  disallowance,  to the extent of
        such disallowance, as the case may be.

10.3    Forfeitures.  Forfeitures and other actuarial gains shall not be applied

        --------------
        in the Plan and for the payment of expenses  relating to the Plan except

        Fund or  Funds  held  under  any  other  pensions  plan or  plans of the
        Company.  Prior to the  satisfaction of all rights of  Participants  and
        Beneficiaries  under the Plan, no part of the principal or income of the
        Trust  Fund  shall be used or  diverted  to  purposes  other  than those

        which  case  the  Participant  will  be  notified  of the  need  for the
        extension  within the initial 90-day period.  The notice of denial shall

        Beneficiary of notice of denial of a claim (or at such later time as may

        other  circumstances),  the  Participant or  Beneficiary  may (a) file a
        request with the Committee that it conduct a full and fair review of the

        review under Section 13.2, the Administrative Committee shall deliver to
        the  Participant or  Beneficiary a written  decision with respect to the
        claim, except that if there are special  circumstances (such as the need
        to hold a hearing)  which require more time for  processing,  the 60-day
        period  shall be  extended  to 120 days upon  notice  within the initial
        60-day period to the  Participant  or  Beneficiary  to that effect.  The
        decision shall be written in a manner calculated to be understood by the
        Participant or Beneficiary  and shall (a) include the specific reason or
        reasons for the  decision  and (b) contain a specific  reference  to the
        pertinent Plan provisions upon which the decision is based. If a written
        notice of denial  is not  provided  to the  Participant  or  Beneficiary
        within such time period, the appeal may be considered denied.

13.4    Committee  Determination  Binding. The Committee shall have the right to
        ---------------------------------
        decide, in their sole and exclusive discretion, all questions respecting
        the  interpretation,  application,  or  administration  of the  rules of
        eligibility for the benefits or services  furnished by the Plan and such
        decisions  shall  be  conclusive  and  binding  upon  all  Participants,

        -----------------------------------
        creation, assignment or recognition of a right to the Retirement Benefit

        Relations Order and for administering distributions under such order.

                annuity  shall  be  fixed  and may not be  changed  on or  after
                benefit payments commence.

        (b)     The  designation  of a beneficiary to receive any remainder of a

                            AMENDMENT AND TERMINATION
                            -------------------------



16.1    Power of Amendment and  Termination.  It is the intention of the Company
        -----------------------------------
        that this Plan will be  permanent.  However,  the Company  reserves  the
        right to terminate its  participation in this Plan at any time by action
        of its board of  directors or other  governing  body.  Furthermore,  the
        Company reserves the power to amend or terminate the Plan at any time by
        action of the Board of  Directors.  Each  amendment  to the Plan will be
        binding on the Company.

16.2    Limitation on Amendment.
        ------------------------

        (a)     Except as expressly provided elsewhere in the Plan, prior to the
                satisfaction  of all  liabilities  with  respect to the benefits
                provided under this Plan, no such amendment or termination shall
                cause any part of the monies contributed  hereunder to revert to
                the Company or to be diverted to any purpose  other than for the
                exclusive  benefit of Participants and their  beneficiaries.  No
                amendment  shall  have the  effect  of  retroactively  depriving
                Participants  of benefits  already  accrued under the Plan.  Any
                amendment  shall become  effective as of the date  designated by
                the Board of Directors.

        (b)     Except  as  permitted  by  Regulations,  no  Plan  amendment  or
                transaction  having  the effect of a Plan  amendment  (such as a
                merger, plan transfer or similar transaction) shall be effective
                to the extent it eliminates  or reduces any "Section  411(d) (6)
                protected  benefit" or adds or modifies  conditions  relating to
                "Section 411(d) (6) protected benefits" the result of which is a
                further  restriction  on  such  benefit  unless  such  protected
                benefits are  preserved  with respect to benefits  accrued as of
                the  later  of  the  adoption  date  or  effective  date  of the
                amendment.  "Section 411(d) (6) protected benefits" are benefits
                described  in  Code  Section   411(d)(6)(A),   early  retirement
                benefits and  retirement-type  subsidies,  and optional forms of
                benefits.

        (c)     If this Plan is amended  and an effect of such  amendment  is to
                increase  current  liability (as defined in Code Section  401(a)
                (29) (E)) under the Plan for a Plan Year, and the funded current
                liability  percentage of the Plan for the plan Year in which the
                amendment  takes  effect  is  less  than  sixty  percent  (60%),
                including the amount of the unfunded current liability under the
                Plan attributable to the amendment, the amendment shall not take
                effect until the  Employer (or any member of a controlled  group
                which includes the Employer)  provides security to the Plan. The
                form and amount of such security shall satisfy the  requirements
                of Code Section  401(a) (29) (B) and (C).  Such  security may be
                released  provided the  requirements of Code Section 401(a) (29)
                (D) are satisfied.


                                      -43-



16.3    Amendment to Vesting  Provision.  If the vesting provisions set forth in
        -------------------------------
        Article VI are amended,  any Participant who, as of the effective day of
        the  amendment  had been  credited  with  three or more years of Vesting
        Service  may  irrevocably  elect  to have  his  nonforfeitable  interest
        computed  without regard to the  amendment.  Notice of the amendment and
        the   availability   of  the  election  shall  be  given  to  each  such
        Participant,  and the election may be  exercised by the  Participant  by
        notice to the Administrative Committee within 60 days after the later of
        (a) the Participant's  receipt of the notice,  (b) the day the amendment
        is adopted or (c) the effective date of the amendment.

16.4    Amendment to Maintain Qualified Status.  Notwithstanding anything to the
        --------------------------------------
        contrary in Section 16.1,  the Board,  in its  discretion,  may make any
        modifications or amendments to the Plan, retroactively or prospectively,
        which it deems  appropriate  to  establish  or maintain the Plan and the
        Trust  Agreement as a qualified  employees' plan and trust under Section
        401 and 501 of the Code.

16.5    Disposition on  Termination.  In the event of the termination or partial
        ---------------------------
        termination  of the Plan,  as defined in the Code,  the interest of each
        affected  Participant who would not have a non-forfeitable  right to one
        hundred  percent  (100%)  of  his  Accrued  Benefit  if  his  employment
        terminated on the date of the termination or partial  termination of the
        Plan  shall  become  non-forfeitable;  however,  in the  event of such a
        termination, each Participant and beneficiary shall have recourse toward
        satisfaction of his non-forfeitable rights to his pension only from Plan
        assets or from the Pension  Benefit  Guaranty  Corporation to the extent
        that it guarantees benefits.

        The amount of the Fund shall be  determined  and,  after  providing  for
        expenses  incident to termination and liquidation,  the remaining assets
        of such Fund shall be allocated in accordance with Section 4044 of ERISA
        for the  purpose of paying  benefits  proportionately  among each of the
        priority groups described below in the following order of precedence:

        (a)     to provide benefits to retired  Participants  and  beneficiaries
                who began  receiving  benefits at least  three years  before the
                Plan termination (including those benefits which would have been
                received for at least three years if the Participant had retired
                that long ago),  based on Plan  provisions  in effect five years
                prior to  termination  during which period such benefit would be
                the least; provided that the lowest benefit in pay status during
                a  three-year  period  shall be  considered  the  benefit in pay
                status for such period;

        (b)     to provide all other Accrued Benefits guaranteed by Federal law;

        (c)     to provide all other vested Accrued Benefits;

        (d)     to provide all remaining non-vested Accrued Benefits.


                                      -44-



        If the assets  available for allocation  under any priority group (other
        than as  provided in priority  groups (c) and (d)) are  insufficient  to
        satisfy  in  full  the  Accrued   Benefits  of  all   Participants   and
        beneficiaries,  the  assets  shall  be  allocated  pro rata  among  such
        Participants  and  beneficiaries  on the basis of the  present  value of
        their  respective  benefits (as of the termination  date). The foregoing
        payments and payments in the event  assets are  insufficient  to pay the
        Accrued Benefits provided in priority groups (c) and (d) will be paid in
        accordance with  regulations  prescribed by the Pension Benefit Guaranty
        Corporation.  The procedure for allocation of assets upon termination of
        the Plan will be carried out in an appropriate  manner as to prevent the
        Plan from being deemed disqualified by the Internal Revenue Service.

        In the  event all  Accrued  Benefits  described  above  have been  fully
        funded, any remaining funds will revert to the Company.

        Notwithstanding  any  other  provision  in this  Section,  if any of the
        provisions  of  this  Section   conflicts  with  ERISA  and  regulations
        thereunder, then ERISA and its regulations shall control.

16.6    Merger,   Consolidation,   or  Transfer.   In  case  of  any  merger  or
        -------------------------------------
        consolidation  with, or transfer of assets or  liabilities  to any other
        plan,  as  provided  in the Code,  the  benefit  of any  Participant  or
        beneficiary  immediately after such merger,  consolidation,  or transfer
        (if the Plan had then terminated) shall be at least equal to the benefit
        such Participant or beneficiary would have received  immediately  before
        such  merger,   consolidation,   or  transfer  (if  the  Plan  had  then
        terminated).

        Plant  Shutdown.  Effective  December 31, 1996 the Systems  Division was
        ---------------
        shut down.  Certain  employees  were covered by the Met-Pro  Corporation
        Negotiated Pension Plan. The Met-Pro Corporation Negotiated Pension Plan
        is merged  into  this Plan  effective  June 1,  1997.  In the event of a
        termination or partial termination or spin-off of this Plan occurring on
        or prior to May 31, 2002,  the allocation of assets of the Plan pursuant
        to this  Article XVI shall be made in such a manner as to give effect to
        any  special  schedule  of  benefits  which  is  required,  pursuant  to
        regulations issued under Section 414(l) of the Internal Revenue Code, to
        be  created  as a  result  of  the  merger  of the  Met-Pro  Corporation
        Negotiated  Pension Plan into this Plan which merger was effective as of
        June 1, 1997.

        (g)     Top  Heavy  Fraction  means  (a) with  respect  to the  Plan,  a
                fraction for a Plan Year the numerator of which is the aggregate
                of  the  present  values  of  the  accrued   benefits  as  of  a
                Determination Date of all Participants who are Key Employees and
                the  denominator of which is the aggregate of the present values
                of  the  accrued  benefits  as of a  Determination  Date  of all
                Participants or (b) with respect to a Required Aggregation Group
                of Plans or a Permissive  Aggregation  Group of Plans a fraction
                (A) the  numerator  of which is the sum of (i) the  aggregate of
                the present values of the accrued  benefits as of the applicable
                Determination  Date of all  Participants  who are Key  Employees
                under all defined  benefit plans included in that group and (ii)
                the aggregate credit balances as of the applicable Determination

                (B) the  denominator of which is the sum of (i) the aggregate of
                the present values of the accrued  benefits as of the applicable
                Determination Date of all Participants under all defined benefit
                plans  included  in the  Group  and  (ii) the  aggregate  credit
                balances as of the applicable Determination Date in the accounts
                of  all  Participants  under  all  defined   contribution  plans
                included in the group.

                In computing a Top Heavy Fraction for a Plan Year, the following
                rules shall apply:  (a) the present value of accrued benefits as
                of a Determination  Date under each defined benefit plan and the
                aggregate account balances as of a Determination Date under each
                defined  contribution  plan shall be increased by the  aggregate
                distributions  made from that plan to  Participants  during  the
                five year  period  ending  on the  Determination  Date,  (b) the
                accrued  benefit under any defined  benefit plan and the account
                balance under any defined contribution plan of a Participant who
                has not  performed  services  for an Employer at any time during
                the five-year period ending on the  Determination  Date shall be
                disregarded,  (c) the present value of accrued  benefits under a
                defined benefit plan as of a  Determination  Date and the credit
                balance under a defined contribution plan shall be determined as
                of that plan's  valuation  date which occurs during the 12-month
                period ending on the  Determination  Date,  (d) in the case of a
                Required  Aggregation Group or a Permissive  Aggregation  Group,
                the Determination  Date of each Plan included in the group shall
                be the Determination  Date that occurs in the same calendar year
                as the  Determination  Date of the  Plan,  (e) in the  case of a
                Required Aggregation Group or a Permissive Aggregation Group, in
                determining the present value of accrued  benefits the actuarial
                assumptions  set  forth  for  this  Plan  shall  be used for all
                defined  benefit  plans,  and  (f) in  the  case  of a  Required
                Aggregation  Group or Permissive  Aggregation  Group the present
                value of the accrued benefits under all defined benefit plans of
                Participants  other than Key Employees shall he determined based
                upon the method  used  uniformly  for accrual  purposes  for all
                defined benefit plans but if there is no uniform  method,  based
                upon the benefit  accrual rate which does not exceed the slowest
                accrual  rate  permitted  under the  fractional  accrual rule of
                Section 411(b)(l)(C) of the Internal Revenue Code.

                Fraction for that Plan Year exceeds 60 percent (a) for the Plan,
                if the  Plan is not  part of a  Required  Aggregation  Group  of
                Plans, (b) for the Required  Aggregation  Group of Plans, if the
                Plan is part of a Required  Aggregation  Group of Plans,  or (c)
                for the Permissive  Aggregation  Group of Plans,  if the Plan is
                part of a Permissive  Aggregation  Group of Plans and a Required
                Aggregation Group of Plans.

17.2    When Top Heavy Provisions Apply.  Notwithstanding any other provision of
        -------------------------------
        this Plan,  the provisions of this Article XVII shall apply with respect

        ----------------
        termination  of employment  of a Participant  who is not a Key Employee,
        the  Participant's  retirement  benefit shall be equal to the greater of
        (a) the Retirement  Benefit that  otherwise  would be determined for the
        Participant under Article V if no effect were given to this Article XVII
        and  (b)  the  product  of  2  percent  of  the  Participant's   Average
        Compensation and the number of years of his or her Years of Service (not
        in excess of 10)  credited  with respect to Plan Years in which the Plan
        is a Top Heavy  Plan and he or she is a  Participant.  For  purposes  of
        determining a Participant's  Retirement Benefit under this Section 17.3,
        it shall be assumed that payment of the  Retirement  Benefit shall be in
        the  form  of  a  straight  life  annuity  without  ancillary  benefits,
        commencing on the Participant's Normal Retirement Date. If a Participant
        who is not a Key  Employee  participates  in both a defined  benefit and
        defined  contribution  Plan, the Company is not required to provide such
        Participant  both the minimum benefit and the minimum  contribution.  In
        such event, the Participant  shall receive the benefit described in this
        Section.

        The retirement  benefit  determined  under this Section 17.3 shall apply
        even though as a result of other Plan  provisions a  Participant  who is
        not a Key  Employee  would  not  otherwise  have been  entitled  to have
        received a benefit or would have received a lesser  benefit  because (i)
        he or she  failed to make  mandatory  employee  contributions  under the
        Plan; (ii) his or her Compensation is less than the stated amount; (iii)
        he or she is not  employed  on the last day of the  accrual  computation
        period or (iv) the Plan is integrated with Social Security.

17.4    Vesting.  For any  Plan  Year  the Plan is a Top  Heavy  Plan,  the non-
        -------
        forfeitable  portion of the Retirement  Benefit of a Participant  who is
        credited  with at least one Hour of Service  during that Plan Year under
        Section  1.24 shall be the greater of the  percentage  determined  under
        Article VI and a percentage based on the Participant's  Years of Service
        as follows:

              Number of Years of Service                  Vesting Percentage

                        0                                         0
                        1                                         0
                        2                                        20
                        3                                        40
                        4                                        60
                        5                                        80
                    6 or more                                   100


                                      -48-


17.5    Change  From Top Heavy  Vesting.  If the Plan is a Top Heavy  Plan for a
        -------------------------------
        Plan  Year and  ceases to be a Top Heavy  Plan for the  subsequent  Plan
        Year, the change in the vesting provision under this Section 17.5 to the
        vesting provision under Article VI shall for purposes of Section 16.3 be
        treated as an amendment of the vesting provisions of the Plan.

17.6    Combined Limitation.  For any Plan Year in which the Plan is a Super Top
        -------------------
        Heavy  Plan,  1.0 shall be  substituted  for 1.25 in  clause  (1) of the
        definition of Defined Benefit Plan Fraction  (Section 9.1(b)) and clause
        (2) of the  definition of Defined  Contribution  Plan Fraction  (Section
        9.1(c)).  The foregoing  shall not apply for Plan Years  beginning on or
        after the first day of the 2000 limitation year.

                                   APPENDIX A

          ACTUARIAL ASSUMPTIONS USED TO DETERMINE ACTUARIAL EQUIVALENCE
          -------------------------------------------------------------


1.      "Actuarial  Equivalent".  Subject to Section 2, the Actuarial Equivalent
        -----------------------
        of a given benefit shall be determined using the following assumptions:

        (a)     Interest - 8 percent per annum compounded annually.

        (a)     Subject to paragraph (b) below, if a Participant's  benefits are
                to be paid in a single sum, then in no event shall the Actuarial
                Present Value of a  Participant's  Vested  Interest be less than
                the greater of:

                (i)     such present value  determined  based on the assumptions
                        set forth in Section 1 above, or

                (ii)    such  present  value  determined  based on the  interest
                        rates  which  would be used as of the  first  day of the
                        Plan Year in which  distribution  occurs by the  Pension
                        Benefit  Guaranty  Corporation  for  a  trusteed  single
                        employer  Plan  and the  mortality  table  specified  in
                        paragraph (b) of Section 1.

        (b)     Effective September 1, 1995, if a Participant's  benefits are to
                be paid in a single sum,  then in no event  shall the  Actuarial
                Equivalent  present value of a Participant's  Vested Interest be
                less than:

                (i)     such present value  determined  based on the assumptions
                        set forth in Section 1 above, or

                (ii)    such  present  value   determined  using  the  following
                        assumptions:

                        (A)     Interest  -  the  annual  rate  of  interest  on
                                30-Year Treasury  securities as published by the
                                IRS for the month  prior to the  first  month of
                                the Plan Year in which the distribution occurs.

                        (B)     Mortality  -  determined  under  the  applicable
                                mortality table under Code Section 417(e).


                                      -52-


        (c)     Solely for the purpose of determining  an actuarial  increase in
                benefits due as a result of the  commencement  of such  benefits
                after the Participant's  attainment of age 70 1/2, the following
                assumptions will be used:
