4.1  Each year on the day following the Annual Meeting of Shareholders of the
     Company, the Company shall credit the Account of each Non-Employee Director
     who serves on the Board on that day with the number of Common Stock
     Equivalents determined by dividing one-half of such Director's Retainer by

     Exchange Composite Transactions during the 5 days for which such price is
     available immediately preceding such day of crediting.  The Account of any
     person who ceases to be a Director prior to April 16, 1999, shall be
     credited with no more than 10 such Annual Contributions and the total
     number of such Annual Contributions made to his or her Account under this
     Section 4.1 plus the number which is multiplied by $10,000 to determine the
     amount credited to the Account under Section 4.2 will not exceed 10.  Any
     Non-Employee Director who is a Director of the Company on or after April
     16, 1999 and whose total number of Annual Contributions was limited to 10
     under the Plan in effect prior to April 16, 1999, shall have credited to
     his or her Account such additional Annual Contributions and Dividend
     Equivalents as are necessary so that such Account is credited with the
     number of Common Stock Equivalents it would have had credited if such
     limitation had never existed.

4.2  On the day following the 1988 Annual Meeting of Shareholders of the
     Company, the Company shall credit the Account of each Non-Employee Director
     who is age 61 or older on that date with the number of Common Stock
     Equivalents determined by (1) multiplying $10,000 times his or her number
     of full fiscal years of Service, but such number of full fiscal years of
     Service shall not exceed the number determined by subtracting 60 from the
     Non-Employee Director's age on the day immediately following the 1988
     Annual Meeting of Shareholders and (2) then dividing that amount by the
     average closing price of the Common Stock in the

                                       3

5.   PAYMENTS OF BENEFITS.
     --------------------

5.1  Payments from the Account will be made in the form of Common Stock,
     provided that payment with respect to any partial shares of Common Stock
     shall be made in the form of cash.  However, payments from the Account of
     any Participant who ceased to be a director of the Company before August
     15, 1996 shall continue to be paid in the manner provided by the Plan as
     effective on August 15, 1996.

5.2  Subject to Section 5.4 and Section 5.5, a Participant may elect to have the
     amount deferred paid in from one to 15 annual installments after he or she
     shall cease to be a director of the Company.

     Such installment(s) shall commence upon or following

          (i)   a specified date;
          (ii)  an event certain;
          (iii) the earlier of a specified date or an event certain.

     Installments shall continue to be payable as soon as practicable after the
     first day of January of each year thereafter.

     Subject to Sections 5.4 and 5.5, payment of deferred amounts shall commence
     no later than January of the first calendar year which is the later of:

          (i)  the year following attainment of age seventy (or such other age
               as may supersede the age referred to in Section 403(f)(3) of
               Title 42 United States Code); or

          (ii) the year following such Participant's retirement.

     The number of shares of Common Stock paid in each installment shall be
     equal to the whole number obtained by dividing the number of Common Stock
     Equivalents then credited to the Participant's Account by the number of
     unpaid

                                       5
<PAGE>

     installments. Common Stock Equivalents with respect to which payment has
     not yet occurred shall continue to be credited with Dividend Equivalents
     until paid. However, no installment paid from the Account may be in an
     amount less than 20 shares of Common Stock, and, to the extent necessary,
     installments shall be accelerated to provide for such minimum installments.
     As of the date on which the last payment of benefits is made to a
     Participant from the Account, the Company shall pay the Participant, in
     cash, an amount equal to the value of any remaining fractional Common Stock
     Equivalent based on the closing price of the Common Stock on the New York
     Stock Exchange Composite Transactions on the last date such price is
     available prior to the payment date.

5.3  Death or Disability
     -------------------

          (i)  Subject to Section 7, in the event of the death or disability of
               a Participant either while serving as a director of the Company
               or prior to the commencement of any payments hereunder, any
               amount due under the Plan shall be paid in a lump sum to the
               Participant's beneficiary, or in the case of disability, to the
               Participant, as soon as practicable after the death or
               disability.

          (ii) Subject to Section 7, in the event of the death or disability of
               a Participant on or after the commencement of installment
               payments, in accordance with Section 5.2, payments shall continue
               to paid to the Participant's beneficiary, or in the case of
               disability, to the Participant, in accordance with the election
               made by the Participant in accordance with Section 5.2; provided,
               however, that the Secretary of the Committee shall have the power
               to accelerate the payment of any installment(s) because of
               hardship or other circumstances deemed by him, in his discretion,
               to warrant such acceleration.

5.4  Payment Elections
     -----------------

     Subject to Section 5.6, a Participant may elect the number and the date or
     event for the commencement of installment payments in accordance with the
     following:

          (i)  Such elections must be made at least six months and ten days
               prior to the first payment date; and

          (ii) In all cases, the elections must be made in the calendar year
               preceding the first payment date.

5.5  Notwithstanding any other provision of this Plan, the first installment to
     a Participant out of the Account shall not be paid until six months and ten
     days after the Participant shall cease to be a director of the Company.

5.6  Notwithstanding any other provision of this Plan, any Participant who,
     pursuant to any income tax laws to which he or she is subject, would be
     immediately taxed on any amounts credited under the Plan may not elect the
     number and the date or event for the commencement of payments under the
     Plan.  Instead, the payment of all benefits to such Participant (including
     any Dividend Equivalents from the Plan) shall occur as a lump sum payment
     on the first business day which is 6 months and 10 days after the
     Participant's last day as a member of the Board.  In the event of such
     Participant's death prior to receipt of the benefits, the Participant's
     Beneficiary shall be paid the benefits on the first business day which is 6
     months and 10 days after the Participant's last day as a member of the
     Board.

6.   CHANGES IN STOCK.  In the event of any change in the outstanding shares of
     ----------------
     the Common Stock, or in the number thereof, by reason of any stock dividend
     or split, recapitalization, merger, consolidation, exchange of shares or
     other similar change, a corresponding change will be made in the number of
     Common Stock Equivalents and Dividend Equivalents, if any, credited to each
     Account, unless the Committee determines otherwise.

                                       7
<PAGE>

7.   ACCELERATION.  The Committee, in its sole discretion, may accelerate the
     ------------
     payment of benefits hereunder to any Participant or his or her Beneficiary
     for reasons of changes in tax laws or in the event of a Change in Control
     of the Company; provided that no payment of benefits may be accelerated
     hereunder to any Participant or his or her Beneficiary if such Participant
     was a director of the Company on or after November 1, 1990.

     An exception is provided for any Non-Employee Director if any income tax
     laws to which he or she is subject would cause him/her to be immediately
     taxed on amounts credited under the Plan.  Under this exception, the
     requirement that age 70 be attained before a Non-Employee Director becomes
     a Participant is automatically waived by the Committee.  Additionally,
     under this exception, the payment of all benefits under the Plan shall
     occur on the first business day which is 6 months and 10 days after the
     earlier of a Participant's resignation from the Board or death.  In the
     event of such Non-Employee Director's death, either while still an active
     member of the Board or after resignation from the Board but before receipt
     of payment from the Plan, payment shall be made to the Participant's
     Beneficiary on the above referenced date.

8.   CHANGE IN CONTROL. Upon, or in reasonable anticipation of, a Change in
     -----------------
     Control (as defined above), the Company shall immediately make a payment in
     cash to a trustee on such terms as the Senior Vice President, Human
     Resources, and Administration and the Senior Vice President, Finance, or
     either of them, shall deem appropriate (including such terms as are
     appropriate to cause such payment, if possible, not to be a taxable event
     to Participants) of a sufficient amount to insure that Participants receive
     the payment of all amounts as contemplated under the Plan.

9.   GENERAL PROVISIONS.  The entire cost of benefits and administrative
     ------------------
     expenses for this Plan shall be paid by the Company.  This Plan is purely
     voluntary on the part of the Company.  The Company, by action of the Board
     or, except as limited by the Company's bylaws, the Committee, may amend,
     suspend or terminate this Plan in whole or part at any time, but no such
     amendment, suspension or termination shall adversely affect the rights of
     any Non-Employee Director or Beneficiary of a deceased

<PAGE>

     Non-Employee Director with respect to Common Stock Equivalents and Dividend
     Equivalents credited prior to such amendment, suspension or termination or
     Dividend Equivalents which would otherwise have been credited in the future
     with respect to Common Stock Equivalents credited prior to such amendment,
     suspension or termination.

     No rights under the Plan may be transferred or assigned except that a
     Participant may designate, in writing filed with the Secretary of the
     Company, his spouse or children, a trustee or his or her executor or
     executrix as Beneficiary to receive any unpaid amounts under the Plan after
     the death of the Participant.  In the absence of any such designation or in
     the event that the designated person or entity shall not be in existence at
     the time a payment under the Plan comes due, the Beneficiary of the
     Participant shall be the Participant's legal representative.

     designated by a Participant for in-service withdrawal, in accordance with
     provisions of either the IC Plan or MAP, whichever is applicable, shall be

     (a)  A Participant may elect a payment schedule applicable to his/her
          Account provided such election is filed with the Administrator:

          (1)  Prior to the Participant's Retirement Date; and

          (2)  In the year prior to the year the first payment is to be made

          (2)  Quarterly, semiannual or annual installments - to be made over a

          of Account; 2nd installment = 1/9 of Account; 3rd installment = 1/8 of

          that the Participant must elect to begin installments no later than

          termination date occurs.  Installments must begin no earlier than the
          Plan Year after the Plan Year of the Participant's election and as of
          the

                                 -Page 5.2-
<PAGE>

          first day of the first quarter which is at least six (6) months and 10
          days following the Participant's election. The payment schedule
          elected by the Participant shall apply to his/her entire Account. Each
          installment shall be calculated by dividing the Participant's account
          balance by the remaining number of installments (e.g.: Five annual
          installments shall be paid: 1st installment = 1/5 of Account; 2nd
          installment = 1/4 of Account, etc.). If the installment payment is to
          be in the form of PPG Stock, any stock increment shall be rounded down
          to the nearest whole stock share. Any remaining stock increments shall

               later

          (ii) the year in which the 30th day following the Participant's
               termination occurs; and

          shall be paid during the first quarter of the applicable year
          specified in (i) or (ii) above.

     (d)  In the event the Administrator determines, in his sole discretion,
          that a termination is "for cause," or is otherwise potentially adverse
          to the Company's interest, as for example, a Participant's termination
          in order to accept a position with a major competitor, the Participant
          shall have no election with respect to payment of his/her Account.
          Such Participant shall receive his/her entire Account balance as of
          the first day of the first quarter immediately following his/her
          termination date.

     (e)  Payment schedules pursuant to this Section 5.03 shall supersede any
          prior payment election(s) filed with the Administrator.

     (f)  In accordance with authority delegated to the Administrator by the
          Committee at its meeting on September 20, 1995, the Administrator

          claimant within ninety (90) days following the date on which the claim
          was filed, except that if special circumstances require an extension
          of time, the Administrator shall notify the claimant of this need

          and shall contain the following information:

          (1)  The date on which the denial was received by the claimant;

          (2)  The date on which the claimant's request for review was filed
               with the Administrator;

          representative, an opportunity to review documents pertinent to the
          claim, and shall conduct a full and fair review of the claim and its
          denial.  The Administrator's decision on such review shall be
          furnished to the claimant in writing, and shall be written in a manner
          calculated to be understandable to the claimant.  Such decision shall
          include a statement of the specific reason(s) for the decision,
          including references to the specific provision(s) of the Plan relied
          upon.

          The written notice from the Administrator shall be furnished to the
          claimant within sixty (60) days following the date on which the
          request for review was received by the Administrator, except that if
          special circumstances require an extension of time, the Administrator
          shall notify the claimant of this need within such 60-day period.
          Such notice shall inform the claimant the nature of the circumstances
          necessitating the need for additional time and the date by which the
          claimant will be furnished with the decision regarding the claim.
          Such extension may provide for up to an additional 60 days.

8.01 Amendment of the Plan
     ---------------------

     Except as provided in Section X, the Committee may amend the Plan, in whole

     Except as provided in Section X, the Administrator shall have the authority
     to adopt amendments to the Plan, in whole or in part, at any time,
     necessary for the implementation and/or administration of the Plan, which

     accrued in Participants' Accounts.

     Except as provided in Section X, the Committee may terminate the Plan at

     determination of the Administrator under this Section 8.03 shall be binding
     and conclusive.

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

10.01 Payments to a Trustee
      ---------------------

      Upon, or in reasonable anticipation of, a Change in Control, as defined in
      Section 10.02 below, the Senior Vice President, Human Resources and
      Administration and the Senior Vice President, Finance, or either of them
      or their successor, shall cause an amount, as they deem appropriate, to be
      paid to a trustee on such terms as they shall deem appropriate (including
      such terms as are appropriate to cause such payment not to be a taxable
      event to Participants, if possible, and to cause such Awards to be
      distributable to Participants in accordance with elections filed with the
      Administrator). Such amount shall be paid in cash and shall be sufficient,
      at a minimum, to equal to all deferred amounts credited to the Investment
      Accounts, the Transferred Interest Account, and the PPG Stock Account.
      Amounts in the PPG Stock Account shall be converted to cash on the basis
      of the fair market value of PPG Stock on the date of the occurrence of the
      Change in Control, or, if higher, within 30 days of such date. Amounts in
      the Investment Accounts shall be converted to cash on the basis of the
      fair market value of the appropriate Investment Account on the date of the
      occurrence of the Change in Control, or, if higher, within 30 days of such
      date.

10.02 Definition:  Change in Control
      ------------------------------

      A "Change in Control" shall mean:

      (a)  The acquisition by any individual, entity or group (within the
           meaning of Section 13(d)(3) or 14(d)(2) of the Securities Exchange
           Act of 1934, as amended (the "Exchange Act")) (a "Person") of
           beneficial ownership (within the meaning of Rule 13d-3 promulgated
           under the Exchange Act) of 20% or more of either (i) the then
           outstanding shares of common stock of the Company (the "Outstanding
           Company Common Stock") or (ii) the combined voting power of the then
           outstanding voting securities of the Company entitled to vote
           generally in the election of directors (the "Outstanding Company
           Voting Securities").

           For purposes of this subsection (a) the following acquisitions shall
           not constitute a Change in Control:

           Any acquisition directly from the Company;

           Any acquisition by the Company;

           Any acquisition by any employee benefit plan (or related trust)
           sponsored or maintained by the Company or any corporation controlled
           by the Company; or

                                 -Page 10.1-

          Any acquisition by any corporation pursuant to a transaction which
          complies with clauses (i), (ii) and (iii) of paragraph (c) of this
          Section 10.02.

     (b)  Individuals who, as of September 20, 1995, constitute the Board (the
          "Incumbent Board") cease for any reason to constitute at least a
          majority of the Board; provided, however, that any individual
          becoming a director subsequent to such date whose election, or
          nomination for election by the Company's shareholders, was approved
          by a vote of at least a majority of the directors then comprising the
          Incumbent Board shall be considered as though such individual were a
          member of the Incumbent Board, but excluding, for this purpose, any
          such individual whose initial assumption of office occurs as a result
          of an actual or threatened election contest with respect to the
          election or removal of directors or other actual or threatened
          solicitation of proxies or consents by or on behalf of a Person other
          than the Board; or

     (c)  Approval by the shareholders of the Company of a reorganization,
          merger or consolidation or sale or other disposition of all or
          substantially all of the assets of the Company (a "Business
          Combination"), in each case, unless, following such Business
          Combination:

          (i)  All or substantially all of the individuals and entities who were
               the beneficial owners, respectively, of the Outstanding Company
               Common Stock and Outstanding Company Voting Securities
               immediately prior to such Business Combination beneficially own,
               directly or indirectly, more than 60% of, respectively, the then
               outstanding shares of common stock and the combined voting power
               of the then outstanding voting securities entitled to vote
               generally in the election of directors, as the case may be, of
               the corporation resulting from such Business Combination
               (including, without limitation, a corporation which as a result
               of such transaction owns the Company or all or substantially all
               of the Company's assets either directly or through one or more
               subsidiaries) in substantially the same proportions as their
               ownership, immediately prior to such Business Combination of the
               Outstanding Company Common Stock and Outstanding Company Voting
               Securities, as the case may be;

          (ii) No Person (excluding any employee benefit plan (or related trust)
               of the Company or such corporation resulting from such Business
               Combination) beneficially owns, directly or indirectly, 20% or
               more of, respectively, the then outstanding shares of common
               stock of

                                 -Page 10.2-
<PAGE>

               the corporation resulting from such Business Combination or the
               combined voting power of the then outstanding voting securities
               of such corporation except to the extent that such ownership
               existed prior to the Business Combination; and

         (iii) At least a majority of the members of the board of directors
               of the corporation resulting from such Business Combination were
               members of the Incumbent Board at the time of the execution of
               the initial agreement, or of the action of the Board, providing
               for such Business Combination; or

      (d)  Approval by the shareholders of the Company of a complete liquidation
           or dissolution of the Company; or

      (e)  A majority of the Board otherwise determines that a Change in Control
           shall have occurred.

10.03 Plan Provisions

      Following a Change in Control, the Plan may not be amended and may not be
      terminated.  Upon a Change in Control, in accordance with Section 10.01,
      the Plan Document then in existence ("Controlling Plan") shall be provided
      to the Trustee.  The Controlling Plan shall govern all amounts transferred
      and remain in effect until the Trustee has paid all such amounts to
      Participants and/or Beneficiaries.
