     WHEREAS,  The  Principal  Sponsor has  reserved to itself the power to make

     NOW, THEREFORE, The Plan Statement is hereby amended as follows:

1. FORMS OF DISTRIBUTION.  EFFECTIVE FOR DISTRIBUTIONS  MADE ON OR AFTER JANUARY

FOLLOWS:

7.3. FORMS OF DISTRIBUTION.

     7.3.1.  FORMS  AVAILABLE.  At the direction of the  Committee,  the Trustee
shall  make  distribution  of the  Participant's  Vested  Total  Account  to the
Distributee in one of the following ways:

          (a)  VESTED TOTAL ACCOUNTS UNDER $20,000, OR AT LEAST $20,000 IF TOTAL
               ACCOUNT NOT 100% VESTED. If the Distributee is a Participant, and

               (i)  the  Participant's  Vested Total Account is less than Twenty
                    Thousand   Dollars   ($20,000)  as  of  the  Valuation  Date
                    coincident with or next following the occurrence of an Event
                    of Maturity effective as to the Participant, or

               (ii) the  Participant's  Vested Total Account is Twenty  Thousand
                    Dollars  ($20,000)  or  greater  as of  the  Valuation  Date
                    coincident with or next following the occurrence of an Event
                    of  Maturity  effective  as  to  the  Participant,  and  the
                    Participant  is not 100% Vested in the  Participant's  Total
                    Account,

               then the Participant's  Vested Total Account shall be distributed
               in a single lump sum subject to Sections 7.1 and 7.2.

          (b)  VESTED  TOTAL  ACCOUNTS  $20,000 OR GREATER AND TOTAL  ACCOUNT IS
               100% VESTED. If the Distributee is a Participant, and

               (i)  the  Participant's  Vested Total Account is Twenty  Thousand
                    Dollars  ($20,000)  or  greater  as of  the  Valuation  Date
                    coincident with or next following the occurrence of an Event
                    of Maturity effective as to the Participant, and

               (ii) the  Participant is 100% Vested in the  Participant's  Total
                    Account,  then the Participant's  Vested Total Account shall
                    be distributed, at the option of the Participant,  either in
                    a single  lump sum,  or in a series of  substantially  equal
                    installments  payable  quarterly,  semi-annually or annually
                    (as selected by the  Participant)  over a period of time not
                    extending  beyond the life  expectancy of the Participant or
                    the  joint  and  last  survivor   life   expectancy  of  the
                    Participant  and the  Participant's  Beneficiary  subject to
                    Sections 7.2 and 7.3.

          (c)  CONTINUED  INSTALLMENTS TO  BENEFICIARY.  If the Distributee is a
               Beneficiary of a Participant who died while receiving installment
               payments,  then in a series of substantially  equal  installments
               payable  quarterly or annually  (as selected by the  Beneficiary)
               which  provides  distribution  to  such  Beneficiary  at  a  rate
               (considering both time and amount) which is cumulatively at least
               as rapid as the rate of distribution commenced prior to the death
               of the Participant.

          (d)  LUMP SUM TO  BENEFICIARIES.  If the  Distributee is a Beneficiary
               and  (c)  above  does  not  apply  or  is  not   elected  by  the
               Beneficiary,  the  Participant's  Vested Total  Account  shall be
               distributed in a single lump sum.

2. DISTRIBUTION IN CASH OR COMPANY STOCK. EFFECTIVE FOR DISTRIBUTIONS MADE ON OR
AFTER JULY 1, 1994,  SECTION 7.6 OF THE PLAN STATEMENT  SHALL BE AMENDED TO READ
IN FULL AS FOLLOWS:

7.6.  DISTRIBUTION  IN CASH OR COMPANY STOCK.  Distribution  of a  Participant's
Vested Total Account shall be made in cash.  If the  Distributee  has selected a
lump sum  distribution in accordance with Section 7.3, the Distributee may elect
that the portion of the  Participant's  Vested Total Account invested in Company
Stock be distributed in Company Stock; provided, however, that such distribution
must comprise at least 100 shares of Company  Stock.  Any such  distribution  of
Company  Stock shall be based upon the number of shares (as opposed to value) of
Company  Stock held in the  Participant's  Vested Total Account as of the Annual
Valuation Date as of which distribution is being made.

3. TENDER OFFER. EFFECTIVE FOR PLAN YEARS BEGINNING ON OR AFTER JANUARY 1, 1995,
SECTION 10.12 OF THE PLAN STATEMENT SHALL BE AMENDED TO READ IN FULL AS FOLLOWS:

10.12. TENDER OR EXCHANGE OFFER OF COMPANY STOCK.

     10.12.1.  COMMITTEE  DIRECTION.  Notwithstanding  Section 10.6 or any other
provision of this Plan  Statement,  the Committee shall have the right to direct
the Trustee as to any tender,  exchange or similar offer with respect to Company
Stock held by the Plan; provided,  however,  that the Committee may determine in
its discretion  that such right shall be passed through to and exercised by each
Participant or Beneficiary  whose Employer  Account or Suspense Account (whether
or not Vested)  holds  Company Stock  according to the  procedures  described in
Section 10.12.2.

     10.12.2.  PASS-THROUGH.  If the Committee  determines under Section 10.12.1
that  Participants  and  Beneficiaries  shall be given the  right to direct  the
Trustee  with  respect to any tender,  exchange  or similar  offer,  then,  upon
receipt of such offer, the following rules shall apply:

          (a)  PROCEDURES.  The Trustee  shall  forward to each  Participant  or
               Beneficiary  as of the Valuation Date  immediately  prior to such
               receipt,  no later than five business days after such receipt,  a
               copy  of the  offer  accompanied  by the  procedures  by  which a
               Participant  or  Beneficiary  may elect to tender or exchange the
               number of shares held for such  Participant  or Beneficiary as of
               the Valuation Date immediately  prior to such receipt,  which may
               contemplate  that any such  election may be made at a later time.
               Not later than ten business  days prior to the  expiration of the
               offer (the "Expiration  Date"), the Trustee shall furnish to each
               Participant or Beneficiary a form providing binding  instructions
               to the  Trustee  whether  to  accept or reject  such  offer  with
               respect to such number of shares and an envelope addressed to the
               Trustee to return such instructions.  All such instructions shall
               be received by the Trustee no later than five business days prior
               to  the  Expiration   Date  (unless  a  shorter  time  period  is
               acceptable to the Trustee).  Any  Participant or Beneficiary  may
               revoke  such  instructions  by writing  addressed  to the Trustee
               received no later than one business  day prior to the  Expiration
               Date. On the Expiration  Date, the Trustee shall accept the offer
               with  respect  to that  number  of  shares  for  which  it has so
               received instructions that have not been revoked.

          (b)  CONFIDENTIALITY.  Participants and  Beneficiaries  shall have the
               right to  determine  confidentially  whether  the  offer  will be
               accepted.

          (c)  PRORATION.  If less than all shares  offered by the  Trustee  are
               accepted by the offeror,  the shares sold or  exchanged  for each
               Participant  or  Beneficiary  shall be in the  same  ratio to the
               number  of shares in the Total  Account  of such  Participant  or
               Beneficiary  as the total number of shares  accepted bears to the
               total number of shares offered.

          (d)  FUTURE  INVESTMENTS.  The proceeds from the sale of Company Stock
               pursuant  to this  Section  10.12  shall  be  transferred  to the
               Employer   Account   of  a   Participant   or   Beneficiary   and
               (notwithstanding  Section  4.2) shall be  invested by the Trustee
               pursuant  to Section  10.6 and shall not be  invested  in Company
               Stock.   All  future   contributions   of  the  Employer  to  the
               Participant's   Employer   Account   shall  be  credited  to  the
               Participant's Employer Account and (notwithstanding  Section 4.2)
               shall be  invested by the  Trustee  pursuant to Section  10.6 and
               shall not be invested in Company Stock.

4.  SAVINGS  CLAUSE.  SAVE AND  EXCEPT AS  HEREIN  EXPRESSLY  AMENDED,  THE PLAN
STATEMENT SHALL CONTINUE IN FULL FORCE AND EFFECT.


     IN WITNESS WHEREOF, Each of the parties hereto has caused these presents to
be executed, all as of the day and year first above written.
