                     SUMMARY OF MAJOR FEATURES OF THE PLAN

     This summary will inform you of the most important provisions of the Plan.
It is only a summary, however, and is subject to the specific provisions of the
Plan, including the use of certain terms defined in the Plan. The complete text
of the Plan, as amended through December 12, 1996 and approved by the
shareholders of PPG on April 17, 1997, is set forth in this Prospectus beginning
on Page 16. The Plan is not subject to any provisions of the Employee Retirement
Income Security Act of 1974 and is not qualified under Section 401(a) of the
Internal Revenue Code of 1986, as amended (the "Internal Revenue Code").

Background

     The PPG Industries, Inc. Stock Plan (the "Plan") was adopted as the 1984
Stock Option Plan by the Board of Directors on February 16, 1984 and approved by
the shareholders on April 19, 1984. The Plan was amended by the Board of
Directors on February 18, 1988, February 20, 1992 and December 12, 1996, and
those amendments were approved by the shareholders on April 21, 1988, April 16,
1992 and April 17, 1997, respectively.

                                      -3-


Purpose

     The Plan is designed to promote the growth and profitability of the Company
and its subsidiaries by giving Plan participants an opportunity to invest in and
hold the Common Stock and thereby (1) provide them with additional incentive to
cause the Company and its subsidiaries to grow and profit, (2) make their
compensation competitive with opportunities available in competing industries,
and (3) encourage them to continue in the employ of the Company or a subsidiary.

     The Plan authorizes the Committee or the Board (or others by delegation as
described below) to grant (i) Stock Options which are either incentive stock
options under the Internal Revenue Code of 1986 ("Incentive Options") or stock
options not qualified under the Internal Revenue Code of 1986 ("Nonqualified
Options") (Incentive Options and Nonqualified Options are referred to
individually or collectively herein as "Options"), (ii) Stock Appreciation
Rights and (iii) shares of Restricted Stock.  The Awards of Options, Stock
Appreciation Rights and Restricted Stock are hereinafter individually and
collectively called "Awards".

Eligible Recipients

     Eligible recipients of Awards include the Company's Directors and selected
Employees of the Company and the Company's subsidiaries.  Awards and the terms
of Awards to Outside Directors and to other persons who are subject to Section
16 of the Securities Exchange Act of 1934 will be determined by the Board or the
Committee.  Other Employees selected to receive Awards as well as the terms of
such Awards will be determined by the Board or the Committee or by others
designated by the Board or the Committee.  (The granting entities are
hereinafter referred to individually or collectively as the "Award Grantor.")
The number of participants who may be granted Options, Stock Appreciation Rights
and Restricted Stock in the future is not presently known because in each
instance it is in the discretion of the Award Grantor.  However, it is presently
contemplated that the number will be less than 3% of the number of Employees of
PPG and its Subsidiaries.  Neither the existence of the Plan nor the grant of
Options, Stock Appreciation Rights or Restricted Stock pursuant to the Plan
shall create in any recipient the right to continue to be employed by the
Company or a Subsidiary.

                                      -4-


Number of Shares Authorized

     The Plan authorizes the grant of Restricted Stock and Options with respect
to a maximum of 10,000,000 shares of Common Stock (of which no more than 250,000
shares may be Restricted Stock) from and after April 17, 1997 (the "Grant
Authorization"). The issuance by the Company of 18,000,000 shares of Common
Stock is authorized (the "Issuance Authorization"). Common Stock will be
registered as required by the Securities and Exchange Commission regulations
prior to issuance. As of February 28, 1997 there were outstanding 8,008,199
unexercised Options under the Plan. The Issuance Authorization covers all
exercises of Options after April 17, 1997, including the exercise of outstanding
unexercised Options issued before that date, and all Restricted Stock awarded
under the Plan. The Plan also provides that the shares of Common Stock subject
to Options plus the number of shares of Restricted Stock granted to any one
person over the remaining life of the Plan will not exceed 2,000,000 shares. The
Grant Authorization and the Issuance Authorization and the individual limit on
Awards are subject to adjustment in certain events including stock dividends and
stock splits as more fully described later. The Plan also provides that shares
of Common Stock tendered to the Company by participants in exercising Options or
paying withholding taxes are restored to both Authorizations but not to the
individual limit on Awards. Any shares of Common Stock subject to unexercised
Options, and remaining unexercised at the expiration or termination thereof, are
restored to the Grant Authorization but not to the individual limit on Awards.
Restricted Stock issued under the Plan and later forfeited to the Company is
restored to both the Grant Authorization and the Issuance Authorization but not
to the individual limit on Awards. No Options, Stock Appreciation Rights or
Restricted Stock may be granted under the Plan after December 31, 2002, although
Common Stock may be issued after that date with respect to Options or Stock
Appreciation Rights outstanding on that date.

Stock Options

     Types of Options.  Stock Options are rights entitling a recipient to
purchase a stated number of shares of Common Stock at a price established at the
time the Stock Option is granted. Options granted under the Plan may be either
Incentive Options or Nonqualified Options. Incentive Options are Options which
qualify as "incentive stock options" as defined in Section 422 of the Internal
Revenue Code, including the regulations promulgated thereunder. Nonqualified
Options are Options that do not qualify as Incentive Options. At the time of
grant, each Option is designated as an Incentive Option or a Nonqualified
Option.

     Restored Options.  The Board or the Committee may specify at the time of
grant of an Incentive Option, and at or after the time of grant of Nonqualified
Options (including currently outstanding Nonqualified Options), that if the
Optionee surrenders (or certifies

                                      -5-


ownership of) shares of Common Stock in full or partial payment of the Option
Price of an Option and/or if the Optionee surrenders shares of Common Stock or
causes shares of Common Stock to be withheld to pay taxes, the Optionee, subject
to availability of shares of Common Stock under the Plan, shall be granted a new
Nonqualified Option (a "Restored Option") covering a number of shares not
greater than the number so surrendered (or certified as to ownership) and/or
surrendered or withheld to pay taxes. A Restored Option may be granted in
connection with the exercise of an Option which is itself a Restored Option.

     Option Price and Term of Option.  At the time of grant, the Award Grantor
determines the price per share to be paid for the purchase of shares subject to
an Option upon exercise of the Option.  The specified price at which shares of
Common Stock may be purchased upon the exercise of an Option may be not less
than the Fair Market Value of a share of Common Stock on the Date of Grant of
the Option.  The Fair Market Value of a share of Common Stock will be the
closing sale price for any applicable date as reported on the New York Stock
Exchange-Composite Tape.  The Award Grantor may also specify the form of payment
of the Option Price, which may be cash, shares of Common Stock or a combination
of both.  The Award Grantor is also authorized to specify the term during which
an Option may be exercised, which may be not longer than ten (10) years from the
Date of Grant of the Option (or in the case of a Restored Option the remaining
term of the Option, the exercise of which generated the Restored Option).

     Other Option Provisions.  The grant of an Option will be evidenced by an
Award Agreement executed by PPG and the Optionee, specifying the number of
shares of Common Stock subject to the Option, whether the Option is an Incentive
Option or a Nonqualified Option, the Option Price and the Option Expiration Date
and containing such other provisions, not inconsistent with the Plan, as may be
prescribed by the Committee.

Stock Appreciation Rights

     Stock Appreciation Rights may be granted with respect to all or any of the
shares of Common Stock subject to an Option.  Stock Appreciation Rights relating
to an Incentive Option must be granted on the Date of Grant of the related
Option, while those relating to a Nonqualified Option may be granted either on
the Date of Grant of the related Option or thereafter at any time during the
term of the Option.  Stock Appreciation Rights will entitle an Optionee to
receive, upon exercise, a payment equal to the amount by which the value of a
share of Common Stock exceeds the Option Price, multiplied by the number of
shares with respect to which Stock Appreciation Rights are exercised.  Such
value will be the Fair Market Value of a share of Common Stock on the date of
exercise or, in the discretion of the Committee, the average of the Fair Market
Values of a share of Common Stock over such period as the Board or the Committee
may specify.

                                      -6-


Payment of Stock Appreciation Rights may be in the form of cash,
shares of Common Stock, or a combination of both, as the Award Grantor may
specify.  Stock Appreciation Rights will be exercisable only to the extent the
related Option is exercisable and to the extent Stock Appreciation Rights are
exercised the related Option will be deemed to have been exercised.

Restricted Stock Awards

     Shares of Restricted Stock may be awarded by the Award Grantor to any
Eligible Person.  The Award may set forth such terms and conditions including,
but not limited to, forfeiture and vesting provisions and restrictions against
sale, assignment, transfer or other disposition as the Award Grantor may
determine. Recipients of Restricted Stock shall be entitled to all dividends
paid with respect to Restricted Stock during the period of restriction and shall
not be required to return such dividends in the event of forfeiture of the
Restricted Stock. The recipient shall be entitled to vote the Restricted Stock
during the period of restriction.

Adjustment Provisions

     If the Company shall at any time change the number of issued shares of
Common Stock by reason of any stock dividend, stock split or similar change, a
corresponding change will be made in the total number of shares reserved for
grant and for issuance under the Plan, the maximum number of shares available to
any individual through the Plan, and the number of shares covered by each
outstanding Award. In the event of any change in the outstanding shares of
Common Stock, or in the number thereof, by reason of any merger, consolidation,
combination, sale of assets, exchange of shares, recapitalization,
reorganization, spin-off or similar change, the Board or the Committee may make
such changes in the shares or in the numbers or Option Prices of shares, subject
to outstanding Awards, and in the maximum number of shares which may be issued
under the Plan, and in the number of shares of Restricted Stock which may have
been issued, as the Board or Committee may deem to be equitable.

Administration

     The Board of Directors and the Officers-Directors Compensation Committee of
the Board of Directors, the members of which are appointed by and may be removed
by the Board of Directors, both have full power and authority to administer,
implement and interpret the Plan and to determine all questions or controversies
arising in the administration or operation of the Plan.  The Board and the
Committee each may establish, amend or remove rules and regulations relating to
the Plan.  Any determination or decision made or action taken by the Board or
the Committee in connection with the

                                      -7-


Plan will be final, conclusive and binding on all persons, including PPG, its
shareholders and Optionees.

Amendment and Termination

     The Board of Directors may amend, suspend or terminate the Plan, in whole
or in part, at any time, but no amendment may, without shareholder approval, (1)
increase the maximum number of shares which may be issued and for which Awards
may be granted (either in the aggregate or to any individual Participant), (2)
change the manner of determining the minimum Option Price (other than to make
any such change as may be necessary to conform to any then-applicable provision
of the Internal Revenue Code or any regulations thereunder), (3) extend the date
upon which the Plan will terminate, or (4) increase the maximum period during
which Options may be exercised. The Plan will terminate on December 31, 2002,
unless earlier terminated by the Board. No amendment, suspension or termination
may affect adversely, without the Participant's consent, the rights of such
Participant with respect to an Award previously granted.

                        FEDERAL INCOME TAX CONSEQUENCES

     Based on the present provisions of the Internal Revenue Code, and the
regulations thereunder, the Federal income tax consequences of the grant and
exercise of Options and Stock Appreciation Rights, the grant and vesting of
Restricted Stock and the payment of dividends thereon, and the subsequent
disposition of shares of Common Stock acquired under the Plan may be summarized
as set forth below.  The following represents an interpretation of the Internal
Revenue Code and the regulations thereunder and is intended only as a general
guide.  Each individual taxpayer's situation is different and you should seek
the advice of a competent tax advisor before you act.  You should be aware that
PPG has received a ruling from the Internal Revenue Service that, for holding
period purposes, the date of transfer of shares acquired upon the exercise of an
Option will be deemed to be the date on which payment in full of the amount due
upon such exercise is made.

Exercise of Options--Payment of Option Price in Cash

     Nonqualified Options.  No income will be recognized by an Optionee nor will
PPG be entitled to a Federal income tax deduction upon the grant of a
Nonqualified Option.  Upon the exercise of a Nonqualified Option, an Optionee
will recognize ordinary income on the date of transfer of the shares acquired
pursuant to such exercise equal to the amount by which the Fair Market Value of
such shares on the date of transfer exceeds the Option Price paid for such
shares.

                                      -8-


     PPG will be entitled to a corresponding Federal income tax deduction in the
same amount and at the same time that ordinary income is recognized by an
Optionee.

     The Optionee's tax basis in the shares acquired will be equal to the Option
Price plus the amount of ordinary income recognized.  The Optionee's holding
period for capital gains purposes with respect to the shares will begin on the
date ordinary income is recognized.  Upon a subsequent disposition of the
shares, the Optionee will recognize either a long-term or short-term capital
gain (or loss) depending on how long the shares are held before disposition.

EXAMPLE A--Assume an Optionee exercises Nonqualified Options to acquire 200
shares, the Option Price for which is $45.00 per share.  Assume, further, that
the date of exercise is July 25, 1998, that the Fair Market Value of shares of
the Common Stock on July 25, 1998, is $60.00 per share and that the Optionee
makes payment of the Option Price by delivering a check in the amount of $9,000
to PPG on the date of exercise (and thereby makes the date of exercise also the
date of transfer).  The amount of ordinary income to be recognized would be
calculated as follows:

     Fair Market Value on the date of transfer
            of the shares acquired ($60.00 x 200)..................   $12,000.00
     Option Price paid for such shares ($45.00 x 200)..............    -9,000.00
                                                                      ----------

     Amount of Ordinary Income.....................................   $ 3,000.00

     The tax basis of the shares acquired would be $60.00 per share and the
holding period would begin on the date of transfer, July 25, 1998.

     Incentive Options.  No income will be recognized by the Optionee nor will
PPG be entitled to a Federal income tax deduction upon the grant or exercise of
an Incentive Option. Upon the subsequent disposition of the shares acquired,
assuming it is not a disqualifying disposition, the entire difference between
the Option Price and the proceeds received upon disposition will be treated as a
capital gain or loss. A disqualifying disposition will occur to the extent any
of the shares acquired upon exercise of an Incentive Option are disposed of
within two (2) years of the Date of Grant of the Incentive Option or within one
(1) year of the date of transfer of the shares acquired upon exercise of the
Incentive Option. Upon a disqualifying disposition, the Optionee will recognize
ordinary income equal to the excess of the lessor of the proceeds received upon
disposition (in the case of a sale or other taxable disposition) or the Fair
Market Value of the shares on the date of transfer over the Option Price. In the
case of a disqualifying disposition, the Optionee will also recognize long-term
or short-term capital gain (depending on whether the shares are held more than
the applicable long-term capital gains holding period before disposition) to the
extent, if any, that the proceeds received

                                      -9-


exceed the Fair Market Value of the shares on the date of transfer. If the
proceeds received upon a disqualifying disposition are less than the Option
Price, the Optionee will recognize either a long-term or short-term capital loss
depending on how long the shares are held before disposition. In the case of a
disqualifying disposition, PPG will be entitled to a corresponding Federal
income tax deduction equal to the amount of ordinary income recognized by the
Optionee. Optionees should note that, generally, the amount by which the Fair
Market Value on the date of transfer of the stock received upon exercise of an
Incentive Option exceeds the Option Price, constitutes an item of "adjustment"
for "Alternative Minimum Tax" purposes.

     The Optionee's tax basis in the shares acquired will be equal to the Option
Price paid. For capital gains purposes, the Optionee's holding period with
respect to the shares acquired will begin on the date of transfer of the shares
to the Optionee.

EXAMPLE B--Assume an Optionee was granted an Incentive Option on July 17, 1998
and exercises that Incentive Option to acquire 200 shares, the Option Price for
which is $45.00 per share.  Assume further that the date of exercise is July 25,
1999, that the Fair Market Value of the shares on July 25, 1999, is $60.00 per
share and that the Optionee makes payment of the Option Price by delivering a
check in the amount of $9,000 to PPG on the date of exercise (and thereby makes
the date of exercise also the date of transfer).  Lastly, assume the sale of all
of the shares so acquired on August 7, 2000 for a price of $65.00 per share.  No
ordinary income would be recognized either upon exercise or upon subsequent
disposition of the shares acquired (as it is not a disqualifying disposition).

     The tax basis of the shares acquired would be $45.00 per share and the
holding period would begin on the date of transfer, July 25, 1999. The capital
gain to be recognized upon disposition would be calculated as follows:

     Proceeds upon disposition of the shares acquired
           ($65.00 x 200).........................................    $13,000.00
     Option Price paid for such shares ($45.00 x 200).............     -9,000.00
                                                                      ----------

     Amount of Capital Gain.......................................    $ 4,000.00

                                      -10-


Exercise of Options--Payment of Option Price in Shares of Common Stock (Wholly
or Partly)

     Nonqualified Options.  To the extent an Optionee uses shares of Common
Stock already owned to pay the Option Price for a Nonqualified Option, the
exchange (a "Stock Swap") will be treated for Federal income tax purposes as a
tax-free exchange of the shares surrendered for an equal number of shares
acquired.  The Optionee will recognize ordinary income on the date of transfer
of the shares acquired pursuant to such exercise equal to the amount by which
the Fair Market Value of such shares on the date of transfer exceeds the Option
Price paid for such shares.

     PPG will be entitled to a corresponding Federal income tax deduction in the
same amount and at the same time that ordinary income is recognized by the
Optionee.

     The tax basis and holding period for capital gains purposes of the number
of shares acquired equal to the number of shares surrendered will be the same as
the tax basis and holding period of the shares surrendered. The tax basis of the
additional shares acquired will be equal, in the aggregate, to the amount of
ordinary income recognized by the Optionee plus any cash paid. The holding
period for capital gains purposes with respect to the additional shares acquired
will begin on the date the Optionee recognized income with respect to such
shares. Subsequent disposition of the shares acquired will result in either a
long-term or short-term capital gain (or loss) depending on how long the shares
are held before disposition.

EXAMPLE C--Assume an Optionee exercises Nonqualified Options to acquire 200
shares, the Option Price for which is $45.00 per share.  Assume further that the
date of exercise is July 25, 1998, that the Fair Market Value of shares of the
Common Stock on July 25, 1998, is $60.00 per share and that the Optionee makes
payment of the Option Price by certifying to the ownership of 135 shares, the
balance to be paid in cash.  Since the total Option Price which must be paid is
$9,000 (200 shares x $45.00) and the 135 shares to which the Optionee has
certified ownership have a Fair Market Value on the date of exercise of $8,100,
the Optionee must pay the balance of the Option Price, $900, in cash.  Assuming
further that a check in the amount of $900 is received by PPG on July 29, 1998
(which will become the date of transfer) and that the Fair Market Value of
shares of the Common Stock on July 29, 1998, is $62.00 per share.  The amount of
ordinary income to be recognized by the Optionee would be calculated as follows:

                                      -11-


     Fair Market Value on the Date of transfer of the
           shares acquired ($62.00 x 200).......................      $12,400.00
     Option Price paid with shares of Common Stock
        (135 shares x $60.00)...................................       -8,100.00
     Option Price paid in cash ($9,000 - $8,100)                         -900.00
                                                                      ----------

     Amount of Ordinary Income..................................        3,400.00

     The tax basis and holding period for capital gains purposes of the number
of shares acquired equal to the number of shares surrendered (135) would be the
same as the tax basis and holding period of the shares surrendered. The tax
basis of the additional 65 shares would be $66.15 per share ($3,400 + $900 =
$4,300 / 65 shares = $66.15 per share). The holding period for the additional 65
shares would begin on July 29, 1998.

Incentive Options.  If an Optionee uses shares of Common Stock already owned to
pay the Option Price for an Incentive Option, no income will be recognized by
the Optionee with respect to the shares acquired nor will PPG be entitled to a
corresponding Federal income tax deduction.  However, this may result in a
disqualifying disposition if the shares used in the exercise were obtained in a
prior Incentive Option exercise and have not been held for the required holding
period.  After the exchange, all of the shares acquired will be subject to the
disqualifying disposition rules for Incentive Options.  For all other purposes,
the tax basis and holding period for capital gains purposes of the number of
shares acquired equal to the number of shares surrendered will be the same as
those surrendered.  The tax basis of the additional shares acquired will be zero
or any amount paid in cash.  The holding period of the additional shares for
capital gains purposes will begin on the date of transfer of the shares to the
Optionee.  In the case of a disqualifying disposition of any of the shares
acquired, the shares acquired with the lowest basis will be deemed disposed of
first.  Any disposition of acquired shares which is not a disqualifying
disposition will result in a capital gain (or loss) to the Optionee and PPG will
not be entitled to a corresponding Federal income tax deduction.  Optionees
should note that, generally, the amount by which the Fair Market Value on the
date of transfer of the stock received upon exercise of an Incentive Option
exceeds the Option Price, constitutes an item of "adjustment" for "Alternative
Minimum Tax" purposes.

EXAMPLE D--Assume an Optionee was granted an Incentive Option on July 17, 1998
and exercises that Incentive Option to acquire 200 shares, the Option Price for
which is $45.00 per share.  Assume further that the date of exercise is July 25,
1999, that the Fair Market Value of shares of the Common Stock on July 25, 1999
is $60.00 per share and that the Optionee makes payment of the Option Price by
certifying to the ownership of 135 shares, the balance to be paid in cash.
Since the total Option Price which must be paid is $9,000 and the 135 shares to
which the Optionee has certified ownership have a

                                      -12-


Fair Market Value on the date of exercise of $8,100, the Optionee must pay the
balance of the Option Price, $900, in cash. Assume further that a check in the
amount of $900 is received by PPG on July 29, 1999 (which will become the date
of transfer) and that the Fair Market Value of shares of the Common Stock on
July 29, 1999, is $62.00 per share. Lastly, assume that all of the shares
acquired are sold on August 7, 2000 for a price of $65.00 per share. No ordinary
income is recognized either upon exercise or upon the subsequent disposition of
the shares acquired (as it is not a disqualifying disposition). The tax basis
and holding periods of the shares would be determined as follows: The 135 shares
to which the Optionee certified ownership covered the acquisition of 180
Incentive Option shares (135 shares x $60.00 / $45 = 180 shares). One hundred
thirty-five of such 180 shares would have a tax basis and holding period equal
to the tax basis and holding period of the 135 shares surrendered. The remaining
45 shares acquired in the "swap" would have a zero basis. The remaining 20
shares acquired for cash would have a tax basis of $45.00 per share ($900 / 20
shares). The holding period for all 65 new shares would begin on July 29, 1999.

     The capital gain to be recognized upon disposition of the 65 new shares
would be calculated as follows:

     Proceeds upon disposition of the shares acquired
           ($65.00 x 65)..........................................    $4,225.00
     Basis of shares ($0 + $900)..................................      -900.00
                                                                      ---------

     Amount of Capital Gain.......................................    $3,325.00


Restored Options

     Restored Options received as part of a "Stock Swap" will be taxed in the
same manner as any other Nonqualified Option.  Restored Options will not be
taxable upon grant, but will be taxable upon exercise in the same manner as any
other Nonqualified Option as explained above in this "Federal Income Tax
Consequences" section.

Stock Appreciation Rights

     The grant of Stock Appreciation Rights with respect to either an Incentive
Option or a Nonqualified Option will have no Federal income tax consequences for
either the Optionee or PPG. Upon the exercise of Stock Appreciation Rights, the
Optionee will recognize ordinary income on the date of exercise equal to the
amount of cash received and/or the Fair Market Value on the date of exercise of
the shares of Common Stock acquired. PPG will be entitled to a corresponding
Federal income tax deduction equal to the amount of ordinary income recognized
by the Optionee. The Optionee's tax basis in any shares acquired will be equal
to the Fair Market Value of such shares on the date the

                                      -13-


Optionee recognizes ordinary income and the Optionee's holding period
for capital gains purposes will commence on such date.  Upon subsequent
disposition of any shares acquired, the Optionee will recognize either a long-
term or short-term capital gain (or loss) depending on how long the shares are
held before disposition.

EXAMPLE E--Assume an Optionee exercises Stock Appreciation Rights as to 200
shares and that the Option Price as to the underlying Options is $45.00 per
share.  Assume, further, that the date of exercise is August 8, 1998, that the
Fair Market Value of shares of the Common Stock on August 8, 1998, is $60.00 per
share.  Lastly, assume that the Stock Appreciation Rights are paid wholly in
shares (except for cash in lieu of any fractional share).  The value of the
Stock Appreciation Rights would be $3,000 ($60.00 - $45.00 x 200 = $3,000) which
would be paid in the form of 50 shares ($3,000.00 / $60.00 = 50 shares).  The
amount of ordinary income to be recognized would be $3,000.

     The tax basis of the shares acquired would be $60.00 per share and the
holding period would begin on August 8, 1998.

Restricted Stock

     A holder of Restricted Stock will recognize income when the stock becomes
substantially vested. Restricted Stock becomes substantially vested when it is
either transferable or is not subject to a substantial risk of forfeiture. If
the Restricted Stock is subject to restrictions that lapse in increments over a
period of time so that the holder becomes substantially vested in a portion of
the shares as the restrictions lapse, the holder will recognize income in any
tax year only with respect to the shares that become substantially vested during
that year. The income recognized will be equal to the Fair Market Value of those
shares, determined as of the time that the restrictions on those shares lapse.
That income will be taxable at ordinary income tax rates. The tax basis of the
shares acquired will be equal to the amount of ordinary income recognized. The
holding period for capital gain purposes with respect to the shares acquired
will begin on the date the shares become substantially vested. The Company will
be entitled to a deduction in an amount equal to the amount of ordinary income
recognized by the holder of the Restricted Stock.

     A holder of Restricted Stock may elect (a Section 83(b) election) instead
to recognize ordinary income for the taxable year in which he receives an Award
of Restricted Stock in an amount equal to the Fair Market Value of the
Restricted Stock on the date transferred to him (even though the shares are
still not substantially vested). That income will be taxable at ordinary income
tax rates. After the election has been made, no additional compensation will be
includable in gross income when such shares become substantially vested. In
computing gain or loss from the subsequent sale or exchange of such shares,
their tax basis will be the amount of ordinary income recognized as a result

                                      -14-


of the election. Such gain or loss will be taxable at the applicable capital
gains rate. The holding period for capital gains purposes with respect to the
shares for which an election has been made shall begin on the date the shares
were transferred to the holder. Any such election must be made within thirty
days after the transfer of the Restricted Stock to the holder. The Company will
be entitled to a deduction in an amount equal to the amount of ordinary income
recognized by the holder at the time of the election. Use of an 83(b) election
should be coordinated with PPG's Law Department.

     Dividends paid to a holder of Restricted Stock before it is substantially
vested are treated as compensation and are taxed to the holder as ordinary
income and are subject to all employment taxes and W-2 reporting. The Company is
entitled to a deduction equal to such dividends. Dividends paid after Restricted
Stock has become substantially vested are taxed as normal dividends (i.e., taxed
as ordinary income to the holder of the stock) and the Company is not entitled
to deduct the dividend amount. Dividends paid after an 83(b) election are
treated as normal dividends and not as compensation, even though the shares may
still not be substantially vested.

Limitation On Company Deductions

     Under the Internal Revenue Code and regulations, no federal income tax
deduction is allowed for compensation paid to a "covered employee" in any
taxable year of the Company beginning on or after January 1, 1994, to the extent
that such compensation exceeds $1,000,000.  For this purpose, "covered
employees" are generally the chief executive officer of the Company and the four
highest compensated officers of the Company.  This deduction limitation does not
apply to compensation that is performance-based compensation.

     Regulations provide that compensation attributable to a Stock Option or a
Stock Appreciation Right will generally be performance-based compensation if the
grant or Award is made by a "compensation committee" (a committee of the Board
of Directors composed of "outside" directors), the Plan under which the Option
or right is granted states the maximum number of shares with respect to which
Options or rights may be granted during a specified period to any Employee, and,
under the terms of the Option or right, the amount of compensation the Employee
could receive is based solely on an increase in the value of the stock after the
date of the grant or Award. It is intended that Stock Options and Stock
Appreciation Rights granted under the Plan satisfy these requirements to the
extent possible.

specified price may be granted from time to time to those Eligible Persons who
have the ability to make a contribution to the growth and profitability of the
Company or any of its Subsidiaries.  Options granted hereunder may be Incentive

                                      -19-


     (d) The Option Price of each Option shall be as determined by the Board or
the Committee but in no event shall be less than the Fair Market Value of a
share of Common Stock on the Date of Grant.  The Option Price may be paid in
full in the form of cash, shares of Common Stock or a combination of both, as
the Board or the Committee may specify.

     (e) Options may be exercised at such times and in such manner as shall be
prescribed by the Board or the Committee, except that no Option shall be
exercisable under any circumstances more than ten (10) years from the Date of
Grant.

     (f) The Board or the Committee may specify, at the time of grant or, with
respect to Nonqualified Options, at or after the time of grant, that an Optionee
shall be granted a Nonqualified Option (a "Restored Option") in the event that
(i) such Optionee exercises all or part of an Option (an "Original Option") by
surrendering (or certifying ownership of) already owned shares of Common Stock
in full or partial payment of the Option Price under such Original Option and/or
(ii) such Optionee surrenders shares of Common Stock or causes shares of Common
Stock to be withheld to pay withholding taxes in connection with the exercise of
such Original Option.  All Restored Options are subject to the availability of
shares of Common Stock under the Plan at the time of such exercise.  A Restored
Option shall cover a number of shares of Common Stock not greater than the
number of shares of Common Stock surrendered (or to which ownership has been
certified) in payment of the Option Price under such Original Option and/or used
to pay withholding taxes in connection with the exercise of such Original
Option.  Each Restored Option shall have an Option Price equal to the Fair
Market Value of the Common Stock on the Date of Grant of the Restored Option and
shall expire on the Option Expiration Date of the Original Option or such
earlier specific date as the Original Option will expire provided such earlier
date has been established on the Date of Grant of the Restored Option.  The Date
of Grant of a Restored Option shall be the date of exercise of the Original
Option.  A Restored Option shall be exercisable at any time and from time to
time from or after the Date of Grant of the Restored Option (or, as the Board or
the Committee in its sole discretion shall specify in the Award Agreement for
the Restored Option).  An Award Agreement for a Restored Option shall contain
such other terms and conditions, which may include a restriction on the
transferability of the Common Stock received upon the exercise of the Original
Option, as the Board or the Committee in its sole discretion shall deem
desirable and which may be set forth in rules or regulations adopted by the
Board or the Committee or in the Award Agreement evidencing the Restored Option.
Successive Restored Options may be granted to the extent and upon such terms and
conditions consistent with this Section 5(f) as the Board or the Committee in
its sole discretion shall specify.

                                      -20-


6.   Stock Appreciation Rights

     (a) The Board or the Committee may grant Stock Appreciation Rights with
respect to all or any of the shares of Common Stock subject to an Option.  Stock
Appreciation Rights with respect to an Incentive Option may be granted only on
the Date of Grant of the related Option.  Stock Appreciation Rights with respect
to a Nonqualified Option may be granted either on the Date of Grant of the
related Option or at any time thereafter during the Option Term.

     (b) Stock Appreciation Rights shall entitle the Optionee, upon exercise, to
receive a payment equal to the amount by which the value of a share of Common
Stock exceeds the Option Price, multiplied by the number of shares with respect
to which Stock Appreciation Rights are exercised.  Such value shall be the Fair
Market Value of a share of Common Stock on the date of exercise or, in the
discretion of the Board or the Committee, the average of the Fair Market Values
of a share of Common Stock over such period as the Board or the Committee may
specify.  Such payment may be made in the form of cash, shares of Common Stock
or a combination of both, as the Board or the Committee may specify.

     (c) Stock Appreciation Rights may be exercised in such manner and at such
times as may be prescribed by the Board or the Committee, but only to the extent
the related Option is exercisable.  To the extent Stock Appreciation Rights are
exercised, the related Option shall be deemed to have been exercised.

7.   Restricted Stock

     Restricted Stock may be awarded to any Eligible Person.  An Award of
Restricted Stock may set forth such terms and conditions, including, but not
limited to, forfeiture and vesting provisions and restrictions against sale,
assignment, transfer or other disposition as the Board or the Committee may
determine.  Restricted Stock shall be duly issued and transferred by the Company
on such dates as the Award Grantor may determine, and a certificate for such
Restricted Stock shall be issued to each Participant to whom an award is made.
The Participant shall thereupon become a stockholder of the Company with respect
to such Restricted Stock, and shall be entitled to vote and to receive the
dividends on such stock; provided, however, that:  (1) stock certificates for
Restricted Stock shall be imprinted with a legend to the effect that the stock
represented thereby may not be sold, exchanged, transferred, pledged,
hypothecated or otherwise disposed of except in accordance with the terms of the
Plan, and each transfer agent for the Common Stock shall be instructed to such
effect; and (2) upon the date specified in the grant as the "Award Maturity
Date", unless cancelled earlier by the Board or the Committee, the restrictions
imposed upon the Restricted Stock shall lapse, and the Participant shall be
fully vested in the award.

                                      -21-


8.   Number of Shares Available for Issuance and Subject to Awards

     (a) From and after April 18, 2002, the maximum number of shares of Common
Stock as to which Awards may be granted is 14 Million and the maximum number of
shares of Common Stock which may be issued under the plan shall be 30.6 Million.
Any shares of Common Stock subject to Awards that are forfeited or unexercised,
to the extent Options remain unexercised at the expiration or termination
thereof or Restricted Stock is forfeited prior to the Award Maturity Date, may
be subject to the grant of further Awards under the Plan.  In addition, shares
of Common Stock that are surrendered (or to which ownership has been certified)
by Participants as full or partial payment to the Company of the purchase price
of shares being acquired through the exercise of an option granted under this
Plan and any shares surrendered by the Participant or withheld by the Company to
pay withholding taxes in connection with the exercise of an Option shall also be
available for issuance and for the grant of Awards under the Plan.  The number
of shares which may be issued under the Plan and as to which Options may be
granted shall be further subject to adjustment in accordance with Section 12.

     (b) In no event, except as subject to adjustment as provided in Section 12,
shall more than two hundred fifty thousand (250,000) shares of Common Stock be
cumulatively available for issuance as Restricted Stock under the Plan.

     (c) The Common Stock to be issued under the Plan may be either authorized
but unissued shares or issued shares acquired by the Company and held in its
treasury.

9.   Government and Other Regulations

     The obligation of the Company to issue or transfer and deliver shares for
Options exercised under the Plan shall be subject to (1) the effectiveness of a
registration statement under the Securities Act of 1933, as amended, with
respect to such issue or transfer, if deemed necessary or appropriate by counsel
for the Company; (2) the condition that the shares of Common Stock authorized to
be issued hereunder shall have been listed (or authorized for listing upon
official notice of issuance) upon each stock exchange on which outstanding
shares of Common Stock may then be listed; and (3) all other applicable laws,
regulations, rules and orders which shall then be in effect.

10.  Limit on Awards

     More than one Award may be granted to a Participant, but except as subject
to adjustment as provided in Section 12 the aggregate number of shares of Common
Stock subject to Awards granted to any Participant after April 18, 2002 may not
exceed two million (2,000,000) shares.

                                      -22-


11.  No Right to Employment

     Neither the existence of the Plan nor the grant of any Award pursuant to
the Plan shall create in any Participant or Eligible Person the right to
continue to be employed by or to continue as a Director of the Company or a
Subsidiary.

12.  Adjustments Upon Changes in Capitalization

     In the event of any change in the number of outstanding shares of Common
Stock by reason of any stock dividend, stock split or similar change, a
corresponding change shall be made in the numbers, and Option Prices, of shares
subject to outstanding Awards, and in the maximum number of shares which then
remain available for issuance, and in the number of shares of Restricted Stock
which then remain available for issuance under the Plan and the limits as to
Awards to individual Eligible Persons.  In the event of any change in the
outstanding shares of Common Stock, or in the number thereof, by reason of any
merger, consolidation, combination, sale of assets, exchange of shares,
recapitalization, reorganization, spin-off or similar change, the Board or the
Committee may make such changes in the shares, and in the numbers or Option
Prices of shares, subject to outstanding Awards, and in the maximum number of
shares which may be issued under the Plan, and in the number of shares of
Restricted Stock which may have been issued, as the Board or the Committee may
deem to be equitable.  No such change, without the consent of a Participant may
adversely affect the rights of such Participant with respect to an Award
previously granted, and any such change shall be final, conclusive and binding
on all persons, including the Company, its shareholders and Participants.

13.  Amendment and Termination

     The Board may amend, suspend or terminate the Plan, in whole or in part, at
any time, but no amendment may, without shareholder approval, (1) increase the
maximum number of shares which may be issued and for which Awards may be granted
under the Plan, either in the aggregate or to any individual Participant; (2)
change the manner of determining the minimum Option Price, other than to change
the manner of determining the Fair Market Value of the Common Stock to conform
to any then-applicable provision of the Code; (3) extend the date upon which the
Plan shall terminate; or (4) increase the maximum period during which Options
may be exercised hereunder.  The Plan shall terminate on, and no Award may be
granted after, December 31, 2007, or on such earlier date as may be determined
by the Board.  No amendment, suspension or termination of the Plan may affect
adversely, without the consent of the Participant, the rights of such
Participant with respect to an Award previously granted.

                                      -23-


14.  Effective Date

     Subject to its approval by the shareholders of the Company, the Plan shall
be effective as of April 18, 2002.

                                      -24-
