ITEM 1. BUSINESS
 
PPG Industries, Inc., incorporated in Pennsylvania in 1883, is comprised of
three basic business segments: coatings, glass and chemicals. Within these
business segments, PPG has followed a program of directing its resources of
people, capital and technology in selected areas for positions of leadership.
Areas in which resources have been focused are automotive original, refinish,
industrial and architectural coatings; flat glass, automotive original and
replacement glass, aircraft transparencies, continuous-strand fiber glass; and
chlor-alkali and specialty chemicals. Each of the business segments in which
PPG is engaged is highly competitive. However, the diversification of product
lines and worldwide markets served tend to minimize the impact on total sales
and earnings of changes in demand for a particular product line or in a
particular geographic area. Reference is made to "Business Segment
Information" on pages 27 and 28 of the Annual Report to Shareholders, which is
incorporated herein by reference, for financial information relating to
business segments.
 
COATINGS
 
PPG is a major supplier of protective and decorative coatings. The coatings
industry is highly competitive and consists of a few large firms with global
presence and many smaller firms serving local or regional markets. PPG
competes in its primary markets with the world's largest coatings companies,
most of which have operations in North America and Europe, and many smaller
regional coatings companies. Product development, innovation, quality and
customer service have been stressed by PPG and have been significant factors
in developing an important supplier position.
 
The coatings business involves the supply of protective and decorative
finishes for automotive original equipment, appliances, industrial equipment
and packaging; factory-finished aluminum extrusions and coils for
architectural uses; and other industrial and consumer products. In addition to
supplying finishes to the automotive original equipment market, PPG supplies
automotive refinishes to the aftermarket, which are primarily sold through
distributors. In the automotive original and industrial portions of the
coatings business, PPG sells directly to a variety of manufacturing companies.
Product performance, technology, quality and customer service are major
competitive factors. The automotive original and industrial coatings are
formulated specifically for the customer's needs and application methods. PPG
also supplies adhesives and sealants for the automotive industry and metal
pretreatments for automotive and industrial applications.
 
The architectural finishes business consists primarily of coatings used by
painting and maintenance contractors and by consumers for decoration and
maintenance. PPG's products are sold through independent distributors, paint
dealers, mass merchandisers, home centers and directly to some customers.
Price, quality and distribution are key competitive factors in the
architectural finishes market.
 
PPG grew the coatings business through several acquisitions completed during
1997. In September 1997, PPG acquired the U.S. industrial pretreatment
business of Man-Gill Chemical Company; in November 1997, PPG acquired Max
Meyer Duco S.p.A. (Max Meyer), a European supplier of automotive refinish,
fleet finish and decorative coatings, and Phillips Paint Products, a Canadian
industrial coatings manufacturer; and in December 1997, PPG acquired the
worldwide packaging coatings businesses of BASF Lacke + Farben AG, a German
company, and Keeler & Long, a U.S. manufacturer of high performance coatings
and coil coatings. During 1997, PPG also increased its ownership interest from
45% to 100% in two related automotive original coatings companies located in
Brazil and Argentina. PPG plans to sell the European decorative coatings
business of Max Meyer in 1998.
 
The principal production facilities of Coatings are concentrated in North
America and Europe. North American production facilities consist of 17 plants
in the United States, and two each in Canada and Mexico. The three largest
facilities are the Cleveland, Ohio, plant, which primarily produces automotive
original coatings; the Oak Creek, Wis., plant, which produces automotive
original and industrial coatings; and the Delaware, Ohio, plant, which
primarily produces automotive refinishes and certain industrial coatings.
Outside North America, PPG operates three plants each in Spain and Italy, two
plants in Germany, and one plant each in The People's Republic of China,
England, France and Portugal. These plants produce a variety of automotive
original, automotive refinish and industrial coatings. PPG owns equity
interests in operations in Hong Kong, India, South Korea, Taiwan and Thailand.
Additionally, coatings operates 10 service centers in the United States, two
each in Canada and Mexico, and one in Argentina to provide just-in-time
delivery and service to selected automotive assembly plants. Twenty training
centers in the United States, eleven in Europe, five in Asia and one in Canada
are in operation. These centers provide training for automotive aftermarket
refinish customers. Also, four automotive original coatings application
centers that provide testing facilities for customer paint processes and new
products are in operation. The average number of persons employed by the
coatings segment during 1997 was 10,500.

GLASS
 
PPG is one of the major producers of flat glass, fabricated glass and
continuous-strand fiber glass in the world. PPG's major markets are automotive
original equipment, automotive replacement, residential and commercial
construction, aircraft transparencies, the furniture, marine and electronics
industries, and other markets. Most glass products are sold directly to
manufacturing and construction companies, although in some instances products
are sold directly to independent distributors and through PPG distribution
outlets. PPG manufactures flat glass by the float process and fiber glass by
the continuous-filament process.
 
The bases for competition are price, quality, technology, cost and customer
service. The Company competes with six other major producers of flat glass,
six other major producers of fabricated glass and two other major producers of
fiber glass throughout the world.
 
PPG's principal glass production facilities are con- centrated in North Amer-
ica and Europe. Fifteen plants operate in the United States, of which six pro-
duce flat glass, five produce automotive glass products, three produce fiber
glass products and one produces aircraft transparencies. There are three
plants in Canada, two of which produce automotive glass and one produces flat
glass. Four plants operate in Italy; one manufactures automotive and flat
glass, one produces automotive glass products, one produces flat glass and one
produces aircraft transparencies. Three plants are located in France; one
plant manufactures automotive and flat glass and two plants produce automotive
glass products. One plant in England and one plant in the Netherlands produce
fiber glass. PPG owns equity interests in operations in France, Mexico, the
Netherlands, the People's Republic of China, Taiwan, the United States and
Venezuela and a majority interest in a glass distribution company in Japan.
Additionally, there are four satellite operations that provide limited manu-
facturing and just-in-time service to selected automotive customer locations,
and one coating facility for flat glass products. The average number of per-
sons employed by the glass segment during 1997 was 15,800.
 
PPG approved a program in late 1997 to restructure certain glass businesses
that were not meeting strategic and performance objectives. The principal
components of this program include the closure of the Perry, Ga., flat glass
plant, and the sale of the Company's equity interests in two Asian float glass
plants, which are expected to be completed in 1998. PPG recorded a pre-tax
charge of $102 million in 1997 to reflect the estimated cost of this program.
 
CHEMICALS
 
PPG is a major producer and marketer of chlor-alkali chemicals and a supplier
of specialty chemicals. The primary chlor-alkali products are chlorine,
caustic soda, vinyl chloride monomer, chlorinated solvents, chlorinated
benzenes and calcium hypochlorite. Most of these products are sold directly to
manufacturing companies in the chemical processing, rubber and plastics,
paper, minerals and metals, and water treatment industries. The primary
products of PPG's specialty chemicals businesses are Transitions(R) lenses;
optical monomers; precipitated silicas for tire, shoe, and battery separator
businesses; and phosgene and other derivatives and intermediates for the
pharmaceutical, agricultural and fuel additives businesses.
 
In late December 1997, PPG acquired Sipsy Chimie Fine S.C.A., a French
manufacturer of pharmaceutical intermediates.
 
PPG's surfactants business was sold in 1997, resulting in a pre-tax gain of
$59 million.
 
PPG competes with six other major producers of chlor-alkali products. Price,
product availability, product quality and customer service are the key
competitive factors. In the specialty chemicals area, PPG's market share
varies greatly by business; product quality and performance and technical
service are the most critical competitive factors.
 
Chemicals' principal production facilities are concentrated in North America
with five plants in the United States and one plant in Canada. The two largest
facilities, located in Lake Charles, La., and Natrium, W. Va., primarily
produce chlor-alkali products. An additional North American plant began
producing silica-based compounds in Mexico in the first half of 1997. Outside
North America, PPG operates two plants each in Taiwan and the People's
Republic of China, and one each in Australia, France, Ireland and the
Netherlands. PPG owns equity interests in operations in Japan, Thailand and
the United States. The average number of persons employed by the chemicals
segment during 1997 was 4,700.
 
RAW MATERIALS
 
The effective management of raw materials is important to PPG's continued
success. The Company's most significant raw materials are titanium dioxide and
epoxy resins in the coatings segment; sand, soda ash, energy, polyvinyl
butyral and boron-containing minerals in the glass segment; and energy and
ethylene in the chemicals segment. Most of the raw materials used in
production are purchased from outside sources, and the Company has made, and
will continue to make, supply arrangements to meet the planned operating
requirements for the future. For the significant raw material requirements
identified above, and other raw materials, there is more than one source of
supply.
 
RESEARCH AND DEVELOPMENT
 
Research and development costs, including depreciation of research facilities,
during 1997, 1996 and 1995 were
 
                                       2
<PAGE>
 
$266 million, $255 million and $252 million, respectively. PPG owns and
operates ten research and development facilities in the United States, Europe
and Japan to conduct research and development involving new and improved
products and processes. Additional process and product research and
development work is also undertaken at many of the Company's manufacturing
plants.
 
PATENTS
 
PPG considers patent protection to be important. The Company's business
segments are not materially dependent upon any single patent or group of
related patents. PPG received $25 million, $25 million and $27 million from
royalties and the sale of technical know-how during 1997, 1996 and 1995,
respectively.
 
BACKLOG
 
In general, PPG does not manufacture its products against a backlog of orders.
Production and inventory levels are geared primarily to projections of future
demand and the level of incoming orders.
 
NON-U.S. OPERATIONS
 
Although PPG has a significant investment in non-U.S. operations, based upon
the magnitude and location of investments, management believes that the risk
associated with its international operations is not significantly greater than
domestic operations.
 
EMPLOYEES
 
The average number of persons employed worldwide by PPG during 1997 was
31,900.
 
ENVIRONMENTAL MATTERS
 
Like other companies, PPG is subject to the existing and evolving standards
relating to the protection of the environment. Capital expenditures for
environmental control projects were $32 million, $18 million and $25 million in
1997, 1996 and 1995, respectively. It is expected that expenditures for such
projects in 1998 will approximate $30 million with similar amounts of annual
expenditures expected in the near future. Although future capital expenditures
are difficult to estimate accurately because of constantly changing regulatory
standards and policies, it can be anticipated that environmental control
standards will become increasingly stringent and costly.
 
PPG is negotiating with various government agencies concerning 65 cleanup
sites, including 31 sites on the National Priority List ("NPL"). While PPG is
not generally a major contributor of wastes to these sites, each potentially
responsible party or contributor may face governmental agency assertions of
joint and several liability as to each cleanup site. Generally, however, a
final allocation of costs is made based on relative contributions of wastes to
the site. There is a wide range of cost estimates for cleanup of these sites,
due largely to uncertainties as to the nature and extent of their condition
and the methods that may have to be employed for their remediation.
Additionally, remediation projects have been or may be undertaken at certain
of the Company's current and former plant sites. The Company has established
reserves for those sites where it is probable a liability exists and the
amount can be reasonably estimated. As of Dec. 31, 1997 and 1996, PPG had
reserves for environmental contingencies totaling $100 million and $91
million, respectively. Pre-tax charges against income for environmental
remediation costs totaled $34 million in 1997, $27 million in 1996 and $49
million in 1995.
 
The Company's experience to date regarding environmental matters leads PPG to
believe that it will have continuing expenditures for compliance with
provisions regulating the protection of the environment and for present and
future remediation efforts at waste and plant sites. However, management
anticipates that such expenditures, which will occur over an extended period
of time, will not result in future annual charges against income that are
significantly greater than those recorded in recent years. It is possible,
however, that technological, regulatory and enforcement developments, the
results of environmental studies and other factors could alter this
expectation. In addition, a portion of such environmental expenditures may be
recovered from insurers and other third parties. In management's opinion, the
Company operates in an environmentally sound manner, is well positioned,
relative to environmental matters, within the industries in which it operates,
and the outcome of these environmental matters will not have a material
adverse effect on PPG's financial position or liquidity. See Commitments and
Contingent Liabilities, including Environmental Matters, in Management's
Discussion and Analysis for additional information related to environmental
matters.
 
ITEM 2. PROPERTIES
 
See "Item 1. Business" for information on PPG's production and fabrication
facilities.
 
Generally, the Company's plants are suitable and adequate for the purposes for
which they are intended, and overall have sufficient capacity to conduct
business in the upcoming year.
 
ITEM 3. LEGAL PROCEEDINGS
 
PPG is involved in a number of lawsuits and claims, both actual and potential,
including some which it has asserted against others, in which substantial
money
                                       3
<PAGE>
 
damages are sought. These lawsuits and claims relate to product liability,
contract, patent, antitrust, environmental and other matters arising out of the
conduct of PPG's business. PPG's lawsuits and claims against others include
claims against insurers and other third parties with respect to actual and
contingent losses related to environmental matters. Management believes that
the outcome of all lawsuits and claims involving PPG, in the aggregate, will
not have a material effect on PPG's consolidated financial position, results of
operations, or liquidity.
 
ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS
 
None.

Directors who are not also Officers of the Company receive Common
Stock Equivalents pursuant to The Deferred Compensation Plan for
Directors and The Directors' Common Stock Plan. Common Stock
Equivalents are hypothetical shares of Common Stock having a value on
any given date equal to the value of a share of Common Stock. Common
Stock Equivalents earn dividend equivalents which are converted into
additional Common Stock Equivalents but carry no voting rights or
other rights of a holder of Common Stock. The Common Stock Equivalents
credited to Directors under both plans are exempt from registration
under Section 4(2) of the Securities Act of 1933 as private offerings
made only to Directors of the Company in accordance with the
provisions of the plans. The plans are incorporated by reference into
this Form 10-K as Exhibit 10 and 10.3.

Under the Company's Deferred Compensation Plan for Directors, each
Director must defer receipt of such compensation as the Board
mandates. Currently, the Board mandates deferral of one-third of each
payment of the basic annual retainer of each Director. Each Director
may also elect to defer the receipt of (i) an additional one-third of
each payment of the basic annual retainer, (ii) all of the basic
annual retainer, or (iii) all compensation. All deferred payments are
held in the form of Common Stock Equivalents. Payments out of the
deferred accounts are made in the form of Common Stock of the Company
(and cash as to any fractional Common Stock Equivalent). In 1997, the
Directors, as a group, were credited with 6,934 Common Stock
Equivalents under this Plan. The values of the Common Stock
Equivalents, when credited, ranged from $53.50 to $64.

Under the Directors' Common Stock Plan, each Director who neither is
nor was an employee of the Company is credited annually with Common
Stock Equivalents worth one-half of the Director's basic annual
retainer. No more than 10 years of credits may be made for the account
of any director. Upon termination of service, the Common Stock
Equivalents held in a Director's account are converted to and paid in
Common Stock of the Company (and cash as to any fractional Common
Stock Equivalent). In 1997, the Directors, as a group, received 3,162
Common Stock Equivalents under this Plan. The values of those Common
Stock Equivalents, when credited, ranged from $50.375 to $63.313.

            INDEPENDENT AUDITORS' REPORT
 
            To the Board of Directors and Shareholders of PPG
            Industries, Inc.:
 
            We have audited the balance sheet of PPG Industries,
            Inc. and subsidiaries as of December 31, 1997 and
            1996, and the related statements of income and cash
            flows for each of the three years in the period ended
            December 31, 1997, and have issued our report thereon
            dated January 15, 1998; such financial statements and
            report are included in your 1997 Annual Report to
            Shareholders and are incorporated herein by
            reference. Our audits also included financial
            statement schedule II, Valuation and Qualifying
            Accounts, of PPG Industries, Inc. and subsidiaries
            for the years ended December 31, 1997, 1996 and 1995.
            The financial statement schedule is the
            responsibility of the Company's management. Our
            responsibility is to express an opinion based on our
            audits. In our opinion, such financial statement
            schedule, when considered in relation to the basic

            fairly in all material respects the information set

                            MEETINGS OF SHAREHOLDERS
                            ------------------------


    Section 1.1.  Annual Meetings.  An annual meeting of the shareholders shall
    ------------  ----------------                                             
be held each year on such day as the Board of Directors of the Corporation (the
"Board of Directors") may designate, or, if not so designated, on the third
Thursday in April if not a legal holiday, and if a legal holiday, then on the
next business day following.  Annual meetings shall be held at the registered
office of the Corporation, or at such other places, within or without the
Commonwealth of Pennsylvania, as may be designated by the Board of Directors.

    Section 1.2.  Business at Annual Meetings.  The business at each annual
    ------------  ----------------------------                             
meeting of the shareholders shall include:  (a) a review of the business of the
preceding year; (b) the election of directors; and (c) such other business as
may properly be brought before the meeting.  No business may be transacted at
any annual meeting other than (i) matters referred to in the notice of the
meeting or any supplement thereto, (ii) matters otherwise properly brought
before the meeting by or at the direction of the Board of Directors, (iii)
matters properly brought before the meeting by one or more shareholders, but
only in accordance and upon compliance with the provisions of the proxy rules of
the Securities and Exchange commission and the notice provisions of Sections 1.3
and 1.4 of these bylaws and (iv) matters which are incidental or germane to any
of the foregoing.

    Section 1.3.  Nominations of Director Candidates.  Nominations for the
    ------------  -----------------------------------                     
election of directors at a meeting of shareholders may be made only (a) by the
Board of Directors or a committee appointed by the Board of Directors or (b) by
a holder of record of stock entitled to vote in the election of the directors to
be elected; but a nomination (other than a nomination to fill a vacancy
resulting from removal from office by a vote of the shareholders under Article
Sixth of the Restated Articles of Incorporation) may be made

                                       1
<PAGE>
 
by a shareholder only if written notice of such nomination is given, either by
personal delivery or by United States mail, postage prepaid, to the Secretary
and has been received by the Secretary at the principal executive offices of the
Corporation not later than (i) with respect to an election to be held at an
annual meeting of shareholders held on the third Thursday in April, 90 days
prior to such annual meeting and (ii) with respect to an election to be held at
an annual meeting of shareholders held on a date other than the third Thursday
in April or an election to be held at a special meeting of the shareholders, the
close of business on the tenth day following the date of the first public
disclosure of the date of such meeting.  For purposes of this Section 1.3, the
first public disclosure of the date of any special meeting of shareholders or
any annual meeting of shareholders held on a date other than the third Thursday
in April shall be when disclosure of such meeting date is first made in a filing
made by the Corporation with the Securities and Exchange Commission, in any
notice given to the New York Stock Exchange, or in a news release reported by
the Dow Jones News Service, Reuters, Bloomberg, Associated Press or comparable
national news service.  Each notice of nomination from a shareholder shall set
forth: (a) the name and address of the shareholder who intends to make the
nomination and of the person or persons to be nominated; (b) a representation
that the shareholder is a holder of record of stock of the Corporation entitled
to vote at such meeting and intends to be present at the meeting in person or by
proxy to nominate the person or persons specified in the notice; (c) a
description of all arrangements or understandings between the shareholder and
each nominee and any other person or persons (naming such person or persons)
pursuant to which the nomination or nominations are to be made by the
shareholder; (d) such other information regarding each nominee proposed by such
shareholder as would be required to be included in a proxy statement filed
pursuant to the proxy rules of the Securities and Exchange Commission, had the
nominee been nominated by the Board of Directors; and (e) the written consent of
each nominee, signed by such nominee, to serve as a director of the Corporation
if so elected.  The presiding officer of the meeting may refuse to acknowledge
the nomination of any person by a shareholder not made in compliance with the
foregoing procedure.

    Section 1.4.  Other Matters Brought by Shareholders.  For business other
    ------------  --------------------------------------                    
than nominations of director candidates properly brought before an annual
meeting by a shareholder pursuant to clause (c) of Section 1.2 of these bylaws,
the shareholder must give timely notice thereof in writing to the Secretary and
such business must otherwise be a proper matter for shareholder action.  To be
timely, a shareholder's notice shall be given, either by personal delivery or by
United States mail, postage prepaid, to the Secretary and received by the
Secretary at the principal executive officers of the Corporation not later than
90 days prior to such annual meeting, provided that, if such

                                       2
<PAGE>
 
annual meeting is held on a date other than the third Thursday in April, such
written notice must be given within ten days after the first public disclosure
of the date of such meeting.  For purposes of this Section 1.4, the first public
disclosure of the date of any annual meeting of shareholders held on a date
other than the third Thursday in April shall be when disclosure of such meeting
date is first made in a filing by the Corporation with Securities and Exchange
Commission, in any notice given to the New York Stock Exchange, or in a news
release reported by the Dow Jones News Service, Reuters, Bloomberg, Associated
Press or comparable national news service.  Such shareholder's notice shall set
forth (a) as to each matter a brief description of the business desired to be
brought before the meeting, the reasons for conducting such business at the
meeting and any material interest in such business of such shareholder; (b) the
beneficial owner, if any, on whose behalf the notice is given and a specific
representation that the shareholder intends to be present at the meeting in
person or by proxy to present and speak as to such business; and (c) as to the
shareholder giving the notice and the beneficial owner, if any, on whose behalf
the notice is given (i) the name and address of such shareholder, as they appear
on the Corporation's books, and of such beneficial owner and (ii) the class and
number of shares of the Corporation which are owned beneficially and of record
by such shareholder and such beneficial owner.  The presiding officer of the
meeting may refuse to permit any business to be brought before an annual meeting
by a shareholder without compliance with the procedure set forth in this Section
1.4.

    Section 1.5.  Special Meetings.  Special meetings of the shareholders may be
    ------------  -----------------                                             
called at any time, for the purpose or purposes set forth in the call, by the
Board of Directors or by the Chairman of the Board of Directors.  Special
meetings shall be held at the registered office of the Corporation, or at such
other places, within or without the Commonwealth of Pennsylvania, as may be
designated by the Board of Directors or the Chairman of the Board of Directors.

    Section 1.6.  Business at Special Meetings.  No business may be transacted
    ------------  -----------------------------                               
at any special meeting of the shareholders other than matters referred to in the
notice of the meeting or any supplement thereto and matters which are incidental
or germane thereto.

    Section 1.7.  Notice.  Written notice specifying the place, date and time
    ------------  -------                                                    
and the general nature of business to be transacted at each meeting of the
shareholders shall be given by the Secretary to each shareholder of record
entitled to vote at such meeting.

    Section 1.8.  Quorum.  A shareholders' meeting shall not be organized for
    ------------  -------                                                    
the transaction of business unless a quorum is present.  At any meeting, the
presence in

                                       3
<PAGE>
 
person or by proxy of shareholders entitled to cast the minimum number of votes
required by law to constitute a quorum on a particular matter in the absence of
a bylaw to the contrary, or if no such number is required by law, at least a
majority of the votes which all shareholders are entitled to cast on such
matter, shall be necessary and sufficient to organize a meeting for the purpose
of considering such matter.  Notwithstanding the withdrawal of enough
shareholders to leave less than the number of votes required by the preceding
sentence, the shareholders who continue to be present at a duly organized
meeting shall constitute a quorum in order to continue to do business until
adjournment.  If a meeting cannot be organized because a quorum has not
attended, those present in person or by proxy may by majority vote adjourn the
meeting to such time and place as they may determine, and it shall not be
necessary to give notice of such adjourned meeting or the business to be
transacted at such meeting to any shareholder other than by announcement at the
meeting at which such adjournment is taken, unless the Board of Directors fixes
a new record date for the adjourned meeting.

    Section 1.9.  Voting.  The voting at all meetings of the shareholders may be
    ------------  -------                                                       
by voice; but any qualified voter may demand a stock vote, whereupon (i) with
respect to any matter specifically set forth in the notice of meeting, such
stock vote shall be taken by ballot, and (ii) in the case of any other vote,
such stock vote may be taken by ballot, by show of hands, or any other manner
selected by the presiding officer.  If the vote is taken by ballot, each ballot
shall state the name of the shareholder voting and the number of shares voted by
him, and if such ballot be cast by proxy, it shall state the name of the proxy
voting and the number of shares voted by him as proxy.  Each shareholder shall
be entitled to one vote for each share having voting power registered in his
name on the books of the Corporation as of the record date for the determination
of the shareholders entitled to vote at the meeting, and it may be voted by the
shareholder or his duly authorized proxy.  When a stock vote is demanded, all
questions shall be decided by a vote of shareholders present, in person or by
proxy, entitled to cast at least a majority of the votes which all shareholders
present and voting (excluding abstentions) are entitled to cast on the
particular matter, unless otherwise especially provided in these bylaws, in the
Restated Articles of Incorporation, as amended from time to time (the "Restated
Articles of Incorporation"), or by law, and except that in the case of
privileged, subsidiary or incidental motions or questions involving the
convenience of the shareholders present, the presiding officer may call for a
per capita vote, either by voice or by show of hands.  Where a proxy or proxies
represent the holders of shares entitled to cast in aggregate a sufficient
number of votes to adopt a particular resolution, the vote of such proxy or
proxies may, in the discretion of the presiding officer, constitute action by
the shareholders.

                                       4

    A complete list of the shareholders entitled to vote at any meeting of
shareholders, arranged in alphabetical order with the address of and the number
of shares held by each, shall be prepared by the Secretary and shall be produced
and kept open at the time and place of the meeting and shall be subject to the
inspection of any shareholder during the whole time of the meeting.  In lieu of
the making of a list, the Corporation may make the information therein available
at the meeting by any other means.

    Section 1.10.  Proxies; Appointment and Revocation.  Every shareholder
    -------------  ------------------------------------                   
entitled to vote at a meeting of the shareholders or to express consent or
dissent to corporate action in writing without a meeting may authorize another
person or persons, but not more than three, to act for him by proxy.  Every
proxy shall be executed in writing (including telegram, cable or radiogram,
telex, TWX, facsimile transmission or similar transmission), by the shareholder
or by his duly authorized attorney-in-fact, and filed with the Secretary.

    Section 1.11.  Meeting Procedure.  At all meetings of shareholders, the
    -------------  ------------------                                      
Chairman of the Board of Directors shall preside, but in his absence, the
presiding officer shall be designated by the Board of Directors, or if not so
designated, selected by the shareholders present.  The Secretary shall take the
minutes of the meeting, but in the absence of the Secretary or an Assistant
Secretary, the presiding officer shall designate any person to take the minutes
of the meeting.  The presiding officer of any meeting shall determine the order
of business and the procedure at the meeting, including such regulation of the
conduct of discussion as seems to him in order.  The conduct of meetings shall
be governed by accepted corporate practice (not Roberts' Rules), the fundamental
                                            ---                                 
rule being that all who are entitled to take part shall be treated with fairness
and good faith.

Article Sixth of the Restated Articles of Incorporation reads as follows:

    "SIXTH.  6.1  The business and affairs of the corporation shall be managed

by a Board of Directors comprised as follows:

                                       5
<PAGE>
 
    (a)  The Board of Directors shall consist of not less than 9 nor more than
         17 persons, the exact number to be fixed from time to time by the Board
         of Directors pursuant to a resolution adopted by a majority vote of the
         directors then in office;

    (b)  Directors shall, from and after the annual meeting of shareholders held
         in 1987, continue to be classified with respect to the time for which
         they shall severally hold office by dividing them into 3 classes, as
         nearly equal in number as possible.  At such meeting and at each
         succeeding annual meeting of shareholders, the class of directors then
         being elected shall be elected to hold office for a term of 3 years.
         Each director shall hold office for the term for which elected and
         until his or her successor shall have been elected and qualified;

    (c)  Subject to the rights of the holders of any series of preferred stock
         then outstanding, any director, any class of directors, or the entire
         Board of Directors, may be removed from office by shareholder vote at
         any time, with or without assigning any cause, but only if shareholders
         entitled to cast at least 80% of the votes which all shareholders would
         be entitled to cast at an annual election of directors or of such class
         of directors shall vote in favor of such removal; provided, however,
         that no individual director shall be removed (unless the entire Board
         of Directors or any class of directors be removed) in case the votes
         cast against such removal would be sufficient, if voted cumulatively
         for such director, to elect him or her to the class of directors of
         which he or she is a member; and

    (d)  Subject to the rights of the holders of any series of preferred stock
         then outstanding, vacancies in the Board of Directors, including
         vacancies resulting from an increase in the number of directors, shall
         be filled only by a majority vote of the remaining directors then in
         office, though less than a quorum, except that vacancies resulting from
         removal from office by a vote of the shareholders may be filled by the
         shareholders at the same meeting at which such removal occurs.  All
         directors elected to fill vacancies shall hold office for a term
         expiring at the annual meeting of shareholders at which the term of the
         class to which they have been elected expires.  No decrease in the
         number of directors constituting the Board of Directors shall shorten
         the term of any incumbent director.

    6.2  Notwithstanding any other provisions of law, the Restated Articles or
the bylaws of the corporation, the affirmative vote of the holders of at least
80% of the voting power of the then outstanding shares of capital stock of the
corporation entitled to vote in an annual election of directors, voting together
as a single class, shall be required to amend or repeal, or to adopt any
provision inconsistent with, this Article Sixth."

    Section 2.2.  Qualifications and Powers.  No person shall be elected a
    ------------  --------------------------                              
director unless such person owns at least 100 shares of Common Stock of the
Corporation.  In addition to the powers and authority expressly conferred upon
it by these bylaws and the Restated Articles of Incorporation, the Board of
Directors may exercise all such powers of the Corporation and do all such lawful
acts and things in the management of the Corporation as are not, by these
bylaws, by the Restated Articles of Incorporation, or by law directed or
required to be exercised or done by the shareholders.

    Section 2.3.  Organizational Meeting.  The first regular meeting of each
    ------------  -----------------------                                   
newly-elected Board of Directors shall be held immediately following the annual
meeting of the shareholders, and no notice of such meeting shall be necessary in
order legally to constitute the meeting, provided that a quorum of the Board of
Directors shall be present.  At such meeting the Board of Directors shall
organize itself, and may elect officers, appoint members of standing committees

be organized for the transaction of business unless a quorum is present.  At any
meeting, a majority of the directors then in office shall be necessary and
sufficient to organize the meeting.  A meeting at which a quorum is not present
may be adjourned from time to time by a majority vote of those present to such
time and place as they may determine, and it shall not be necessary to give
notice of such adjourned meeting or the business to be transacted thereat other
than by announcement at the meeting at which such adjournment is taken.
Notwithstanding the withdrawal of enough directors to leave less than a
majority, the directors who continue to be present at a duly organized meeting
shall constitute a quorum in order to continue to do business.  Unless otherwise
provided in these bylaws, in the Restated Articles of Incorporation or by law,
the acts of a majority of the directors present and voting (excluding
abstentions) at a duly organized meeting shall be the acts of the Board of
Directors.  The yeas and nays shall be taken and recorded in the minutes at the

the Corporation, whose compensation is to be fixed by the Officers-Directors
Compensation Committee) including, without limitation:  (a) a fixed annual fee;

    ------------  ------------                                                  
Restated Articles of Incorporation or these bylaws, during any emergency period
caused by a national catastrophe or local disaster, a majority of the surviving
members (or the sole survivor) of the Board of Directors who have not been
rendered incapable of acting because of incapacity or the difficulty of
communication or transportation to the place of meeting, shall constitute a
quorum for the sole purpose of electing directors to fill such emergency
vacancies or to reduce the size of the full Board of Directors or both; and a

                                       8
<PAGE>
 
majority of the directors (or the sole survivor) present at such a meeting may
take such action.  Directors so elected shall serve until such absent directors
are able to attend meetings or until the shareholders act to elect directors for
such purpose.  During such an emergency period, if the Board of Directors and
the Policy and Planning Committee are unable to or fail to meet, any action
appropriate to the circumstances may be taken by such officers of the
Corporation as may be present and able.  Questions as to the existence of a
national catastrophe or local disaster and the number of surviving members
capable of acting shall be conclusively determined at the time by the directors
or the officers so acting.

    Section 2.10.  Limitation of Liability.  To the fullest extent that the laws
    -------------  ------------------------                                     
of the Commonwealth of Pennsylvania, as in effect on January 27, 1987, or as
thereafter amended, permit the elimination or limitation of the liability of
directors, no director of the Corporation shall be personally liable for
monetary damages as such for any action taken, or any failure to take any
action, as a director.  This Section 2.10 shall not apply to any actions filed
prior to January 27, 1987, nor to any breach of performance of duty or any
failure of performance of duty by any director occurring prior to January 27,
1987.  The provisions of this Section 2.10 shall be deemed to be a contract with
each director of the Corporation who serves as such at any time while such
provisions are in effect, and each such director shall be deemed to be serving
as such in reliance on such provisions.  Any amendment to or repeal of this
Section 2.10, or adoption of any other Article or bylaw of the Corporation,
which has the effect of increasing director liability shall require the
affirmative vote of at least 80% of the voting power of the then outstanding
shares of capital stock of the Corporation entitled to vote in an annual
election of directors, voting together as a single class.  Any such amendment or
repeal, other Article or bylaw, shall operate prospectively only and shall not
have effect with respect to any action taken, or any failure to act, by a
director prior thereto.

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


    Section 6.1.  Entitlement to Indemnification.  The Corporation shall, to the
    ------------  -------------------------------                               
extent that a determination of entitlement is made pursuant to, or to the extent
that entitlement to indemnification is otherwise accorded by, this Article,
indemnify every person who was or is a director, officer or employee of the
Corporation (hereinafter referred to as the "Indemnitee") who was or is involved
in any manner (including, without limitation, as a party or a witness), or is
threatened to be made so involved, in any threatened, pending or completed
investigation, claim, action, suit or proceeding, whether civil, criminal,
administrative or investigative (including without limitation, any
investigation, claim, action, suit or proceeding by or in the right of the
Corporation) by reason of the fact that the Indemnitee is or was a director,
officer or employee of the Corporation, or is or was serving at the request of
the Corporation as a director, officer, employee, fiduciary or other
representative of another corporation, partnership, joint venture, trust,
employee benefit plan or other entity (such investigation, claim, action, suit
or proceeding hereinafter being referred to as a "Proceeding"), against any
expenses and any liability actually and in good faith paid or incurred by such
person in connection with such Proceeding; provided, that indemnification may be
made with respect to a Proceeding brought by an Indemnitee against the
Corporation only as provided in the last sentence of this Section 6.1.  As used
in this Article, the term "expenses" shall include fees and expenses of counsel
and all other expenses (except any liability) and the term "liability" shall
include amounts of judgments, fines or penalties and amounts paid in settlement.
Indemnification may be made under this Article for expenses incurred in
connection with

                                       15
<PAGE>
 
any Proceeding brought by an Indemnitee against the Corporation only if (1) the
Proceeding is a claim for indemnification under this Article or otherwise, (2)
the Indemnitee is successful in whole or in part in the Proceeding for which
expenses are claimed, or (3) the indemnification for expenses is included in a
settlement of, or is awarded by a court in, a Proceeding to which the
Corporation is a party.

    Section 6.2.  Advancement of Expenses.  All expenses incurred in good faith
    ------------  ------------------------                                     
by or on behalf of the Indemnitee with respect to any Proceeding shall, upon
written request submitted to the Secretary of the Corporation, be advanced to
the Indemnitee by the Corporation prior to final disposition of such Proceeding,
subject to any obligation which may be imposed by law or by provision in the
Articles, bylaws, an agreement or otherwise to repay the Corporation in certain
events.

    Section 6.3.  Indemnification Procedure.
    ------------  --------------------------

    (a)  To obtain indemnification under this Article, an Indemnitee shall
submit to the Secretary of the Corporation a written request, including such
supporting documentation as is reasonably available to the Indemnitee and
reasonably necessary to the making of a determination of whether and to what
extent the Indemnitee is entitled to indemnification.  The Secretary of the
Corporation shall promptly thereupon advise the General Counsel in writing of
such request.

    (b)  The Indemnitee's entitlement to indemnification shall be determined by
a Referee (selected as hereinafter provided) in a written opinion.  The Referee
shall find the Indemnitee entitled to indemnification unless the Referee finds
that the Indemnitee's conduct was such that, if so found by a court,
indemnification would be prohibited by Pennsylvania law.

    (c)  "Referee" means an attorney with substantial expertise in corporate law
who neither presently is, nor in the past five years has been, retained to
represent:  (i) the Corporation or the Indemnitee, or an affiliate of either of
them, in any matter material to either such party, except to act as a Referee in
similar proceedings, or (ii) any other party to the Proceeding giving rise to a
claim for indemnification under this Article.  The Corporation's General
Counsel, if Disinterested (as hereinafter defined), or if not, the Corporation's
senior officer who is Disinterested, shall propose a Referee.  The Secretary of
the Corporation shall notify the Indemnitee of the name of the Referee proposed,
whose appointment shall become final unless the Indemnitee, within 10 days of
such notice, reasonably objects to such Referee as not being qualified,
independent or

                                       16
<PAGE>
 
unbiased.  If the Corporation and the Indemnitee cannot agree on the selection
of a Referee, or if the Corporation fails to propose a Referee, within 45 days
of the submission of a written request for indemnification, the Referee shall be
selected by the American Arbitration Association.  The General Counsel or a
senior officer shall be deemed Disinterested if not a party to the Proceeding
and not alleged in the pleadings as to the Proceeding to have participated in
the action, or participated in the failure to act, which is the basis for the
relief sought in the Proceeding.

    (d)  Notwithstanding any other provision of this Article, to the extent that
there has been a determination by a court as to the conduct of an Indemnitee

any director, officer or employee of the Corporation, which agreements may grant
rights to the Indemnitee or create obligations of the Corporation in furtherance
of, different from, or in addition to, but not in limitation of, those provided
in this Article, without shareholder approval of any such agreement.  Without
limitation of the foregoing, the Corporation may obligate itself (1) to maintain
insurance on behalf of the Indemnitee against certain expenses and liabilities

equitable considerations to the relative benefits to, and the relative fault of,
the Corporation.

    ------------  --------------                                        
advancement of expenses provided for in this Article (1) shall be a contract
right, (2) shall not be exclusive of any other rights to which an Indemnitee may
otherwise be entitled under any Article, bylaw, agreement, vote of shareholders
or directors or otherwise, (3) shall continue as to a person who has ceased to
be a director, officer or employee and (4) shall inure to the benefit of the
heirs and legal representatives of any person entitled to indemnification or
advancement of expenses under this Article.

    ------------  -------------                                                
to be invalid, illegal or unenforceable for any reason (1) such provision shall
be invalid, illegal or unenforceable only to the extent of such prohibition and
the validity, legality and enforceability of the remaining provisions of this
Article shall not in any way be affected or impaired thereby, and (2) to the
fullest extent possible, the remaining provisions of this Article shall be
construed so as to give effect to the intent manifested by the provision held
invalid, illegal or unenforceable.

    Section 6.9.  Effectiveness.  This Article shall apply to every Proceeding
    ------------  --------------                                              
other than a Proceeding filed prior to January 27, 1987, except that it shall
not apply to the extent that Pennsylvania law does not permit its application to
any breach of performance of duty or any failure of performance of duty by an
Indemnitee occurring prior to January 27, 1987.

    Section 6.10.  Amendment.  This Article may be amended or repealed at any
    -------------  ----------                                                
time in the future by vote of the directors without shareholder approval;
provided, that any amendment or repeal, or adoption of any Article of the
Restated Articles or any other bylaw of the Corporation, which has the effect of
limiting the rights granted to directors under this Article, shall require the
affirmative vote of at least 80% of the voting power of the then outstanding
shares of capital stock of the Corporation entitled to vote in an annual
election of directors, voting together as a single class.  Any amendment or
repeal, or such Article or other bylaw, limiting the rights granted under this
Article shall operate prospectively only, and shall not limit in any way the
indemnification provided for herein with respect to any action taken, or failure
to act, by an Indemnitee prior thereto.

Board of Directors may fix a record date, within any applicable limits imposed
by law or the Restated Articles of Incorporation, for the determination of

certify in writing to the Corporation that all or a portion of the shares
registered in the name of the shareholder are held for the account of a
specified person or persons.  The resolution of the Board of Directors adopting
such a procedure may set forth:  (1) the classification of shareholder who may
certify; (2) the purpose or purposes for which the certification may be made;
(3) the form of certification and information to be contained therein; (4) if
the certification is with respect to a record date, the time after the record
date within which the certification must be received by the Corporation; and (5)
such other provisions with respect to the procedure as are deemed necessary or
desirable.  Upon receipt by the Corporation of a certification complying with
the procedure, the persons specified in the certification shall be deemed, for
the purposes set forth in the certification, to be the holders of record of the
number of shares specified in place of the shareholder making the certification.

of the Corporation may issue and register, respectively, from time to time,
without further action or approval by or on behalf of the Corporation, new
certificates of stock of the Corporation to replace certificates claimed to have
been lost, stolen, or destroyed, upon receipt by the transfer agent of an
Affidavit of Loss and Bond of Indemnity in such amount and upon such terms as
may be required by the transfer agent to protect the Corporation, the transfer
agent and registrar against all loss, cost or damage arising from the issuance
of such new certificates, provided that a Bond of Indemnity shall not be
required where not more than five shares of stock are involved.

     (c)  For purposes of subparagraph (a)(1) above, "shareholders' equity"
          shall be exclusive of the aggregate par or stated value of preferred
          stock outstanding, if any, and of any unpaid cumulative dividends

     (d)  The Reserve shall be reduced by the amount of all Awards, including
          any deferred amounts, first from the amount, if any, set aside for the
          year to which the Awards relate, and then from the amounts which have

     (e)  Unawarded amounts set aside prior to the fourth preceding year shall

     (b)  If all or any part of an Award is made in the form of shares of PPG
          Stock, the number of such shares shall be determined by applying the
          Conversion Formula.  Fractional shares shall be paid in cash.

          If the number of such shares is specified, the Reserve shall be
          reduced on account of such shares by an amount determined by applying
          the Conversion Formula in reverse.

          As to shares of PPG Stock which constitute all or any part of an

               Administrator has notice that part or all of the Participant's
               Account may be subject to alienation pursuant to a QDRO.

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

9.01 Change in Control
     -----------------

     (a)  Upon, or in reasonable anticipation of, a Change in Control (as
          defined in section 9.02):

          (1)  Awards in the form of cash shall be made for the year during
               which the Change in Control occurs, and then paid immediately 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, or their successors, shall deem
               appropriate (including such terms as are appropriate to cause
               such payment, if possible, not to be a taxable event to
               Participants) in order to cause the Awards so paid to be paid
               either not later than the end of the first calendar quarter
               following the end of the year to which the Awards relate or on a
               deferred basis in accordance with the elections of Participants
               then in effect as to the timing of the receipt of Awards for such
               year.

          (2)  Participants who are eligible to receive an Award for the Plan
               Year in which a Change in Control occurs shall be eligible to
               receive an Award for the Plan Year following the Change in
               Control.

          (3)  The amount of the Award payable to each Participant shall be:

               one-half of the regular Award if the Change in Control occurs
               during the first six months of the year; or

               the full regular Award, if the Change in Control occurs during
               the second six months of the year

               either calculated at a rating of 12 for all performance
               categories.

          (4)  All deferred amounts credited to the Capital Enhancement Account
               shall be paid immediately 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, or their
               successors shall deem appropriate (including such terms as are
               appropriate to cause such payment, if possible, not to be a
               taxable event to Participants) in order to give effect to the
               elections of Participants with respect to the timing of the
               receipt of such deferred amounts.

     (b)  By way of example of the operation of paragraph (a) above:

                                 - Page 9.1 -
<PAGE>
 
          If the Change in Control occurred on August 1 of a Plan Year, a
          Participant in a position with 1000 total points and an incentive
          award value of $1.75 per point would receive an Award of no less than
          $21,000 calculated as follows: 1000 x 1.75 x 12 = $21,000.

          If the Change in Control occurred on April 1 of a Plan Year, such
          Participant would receive $10,500.

          If the Plan were to be continued to the end of the year, and
          performance exceeded the 12 rating, a higher Award would be paid.

     (c)  Notwithstanding any other provision of this section, if an Award
          ultimately made for such Plan Year is greater than the Award made
          pursuant to this section, the Participant shall be entitled to the
          difference between such Awards.

          If the Participant has elected his/her Award to be deferred, payment
          of such difference shall be made to a trustee in accordance with the
          provisions set forth in subparagraph (a)(4) above.

     (d)  For purposes of this section, the fair market value of a share of PPG
          Stock on any date shall be the closing sale price as reported for such
          date (or, if no price is reported for such date, for the next
          preceding date for which a price is reported) on the New York Stock
          Exchange-Composite Tape.

          (2)  Quarterly, semiannual or annual installments - to be made over a
               period of years, up to a maximum period of 15 years; or

          quarter/year that such installments will begin; provided, however,

          the last quarter of the year in which the fifth anniversary of his/her

     (e)  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.

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

          Participant's Account balance -(e.g.:  Ten annual installments shall
                                          ----                                
          be paid:  1st installment = 1/10 of Account;  2nd installment = 1/9 of

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

     (a)  Upon a finding that the Participant, or Beneficiary if the Participant
          is deceased, has suffered a Financial Hardship, the Administrator may,
          in his sole discretion, permit the acceleration of a withdrawal under
          the Plan in an amount reasonably necessary to alleviate such Financial
          Hardship.

     (b)  If the Administrator permits a withdrawal due to Financial Hardship,
          the Participant shall cease Salary deferrals, if any, and may not make
          any deferrals under the Plan, in the form of an Award or Salary, until
          one entire Plan Year has elapsed following the Plan Year in which such
          withdrawal is made.

     (c)  The Participant shall be required to exhaust all other sources of
          funds, other than the Savings Plan, before the Administrator will

          Beneficiary, may request not more than one (1) Unscheduled Withdrawal
          in a Plan Year.

     (b)  An Unscheduled Withdrawal must be a minimum of 25% of the

     (c)  An election to withdraw 75% or more of the Participant's Interest and
          Stock Accounts shall be deemed a request to withdraw the entire
          Account balance in these two accounts.

     (d)  Prior to payment of any Unscheduled Withdrawal, a penalty of 10% of
          the Unscheduled Withdrawal amount shall be withheld and forfeited (or

          which a Change in Control occurs, or the Plan Year immediately
          following such Change in Control) and the Participant shall cease
          Salary deferrals, if any, effective on the date the withdrawal is paid
          and may not make any deferrals under the Plan, in the form of an Award
          or Salary, until one entire Plan Year has elapsed following the Plan
          Year in which such Unscheduled Withdrawal is made.

          and receipt thereof by such person; nor shall the Administrator
          recognize any assignment in derogation of the foregoing.  No interest

          (1)  The Administrator is authorized to adopt such procedural and
               substantive rules and to take such procedural and substantive
               actions as the Administrator may deem necessary or advisable to
               provide for the payment of amounts from the Plan to an Alternate
               Payee as provided in a QDRO.  Such rules and actions shall be

          Administrator, provided the Participant is alive on such date.

          the Administrator, such designation shall cancel all prior

          in the Participant's Account shall be paid as soon as possible to the
          Participant's estate.

          representative, an opportunity to review documents pertinent to the
          claim, and shall conduct a full and fair review of the claim and its

     Upon, or in reasonable anticipation of, a Change in Control, as defined in

     Administration and the Senior Vice President, Finance, or either of them or
     their successor, shall cause an amount, as they deem appropriate, to be

          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

               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

                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

         the Secretary of the Corporation, it shall become irrevocable for the
         next succeeding calendar year and, unless revoked in writing or
         superseded by a new election effective for calendar years after the
         year in which such revocation or new election is executed, shall

                                      -2-
<PAGE>
 
    (c)  Deferred amounts shall be credited on the books of the Corporation to
         an account in the name of the Participant on the same date that it
         would otherwise be payable and shall thereafter be paid from the
         general funds of the Corporation.  No assets of the Corporation shall
         be segregated or earmarked in respect to any amounts credited to the

         unsecured contractual obligations of the Corporation.

    (d)  The number of Common Stock Units to be credited to the Stock Account
         of a Participant shall be equal to the quotient obtained by dividing
         the unpaid deferred amount to be credited to the Stock Account by the
         closing price of a share of the Common Stock on the date on which such
         deferred amount is credited on the books of the Corporation (or if
         such stock was not traded on that date, on the next preceding date on
         which it was traded), as reported on the New York Stock Exchange
         Composite Transactions.  Dividend Equivalents shall be credited to
         each Stock Account as of each dividend payment date declared with
         respect to the Corporation's Common Stock.



5.  Payment of Deferred Amounts
    ---------------------------

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

    (b)  Subject to Section 5(d), Section 5(e) and Section 5(g), 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
         Corporation.

         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.

                                      -3-
<PAGE>
 
         Subject to Sections 5(d), 5(e) and 5(f), 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.


         Where installments are payable from a Participant's Stock Account, 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 Stock Account by
         the number of unpaid 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 Stock 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
         Stock Account, the Company shall pay the Participant, in cash, an
         amount equal to the value of any remaining fractional Stock Unit 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.

    (c)  Death or Disability
         -------------------

         (i)   Subject to Section 5(g), in the event of the death or disability
               of a Participant either while serving as a director of the
               Corporation 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 5(g), in the event of the death or disability
               of a Participant on or after the commencement of installment
               payments, in accordance with Section 5(b), 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(b); provided, however, that the Secretary of the Committee
               shall have the power to accelerate the

                                      -4-
<PAGE>
 
                payment of any installment(s) because of hardship or other
                circumstances deemed by him, in his discretion, to warrant such
                acceleration.

    (d)  Discontinued Accounts
         ---------------------

         (i)  At such time as any account becomes a Discontinued Account,
         deferred amounts credited to such account for any Participant shall be
         rolled into the Stock Account of such Participant.

         (ii) Any prior election as to installment payments of deferred amounts
         in any Discontinued Account shall be null and void with respect to such
         amounts as of the date such account is terminated and the payment
         elections of the Participant as to amounts then in the Participant's
         Stock Account shall also apply to any amounts from the Discontinued
         Account which are rolled into the Stock Account.


    (e)  Payment Elections
         -----------------

         Any prior election as to the number of installments made by a
         Participant who is serving as a director of the Corporation on February
         19, 1992 shall be null and void.

         Subject to Section 5(d) and Section 5(g), 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.

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

    (g)  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 Compensation that the Board of Directors
         mandates shall be deferred may not elect the number and the date or
                                        ---                                 
         event for the commencement of payments under the Plan.  Instead, the
         payment of

                                      -5-
<PAGE>
 
         all benefits to such Participant (including any Dividend Equivalents
         from the Plan) resulting from the mandatory deferrals 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.  Change in Control
    -----------------

    (a)  Upon, or in reasonable anticipation of, a Change in Control (as defined
         below), the Corporation 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.

   (b)   Except as regards Section 6(c)(v), the Committee shall have the duty
         and the authority to make the determination as to whether a Change in
         Control has occurred, or is reasonably to be anticipated, and,
         concomitantly, to direct the making of the payment contemplated herein.

   (c)   A "Change in Control" shall mean:

         (i)   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 (x) the then outstanding shares of common stock of the
               Company (the "Outstanding Company Common Stock") or (y) 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");
               provided, however, that for purposes of this subsection (i), the
               following acquisitions shall not constitute a Change in Control:
               (a) any acquisition directly from the Company, (b) any
               acquisition by the Company, (c) any acquisition by any employee
               benefit plan (or related trust) sponsored or maintained by the

         (ii)  Individuals who, as of the date hereof, 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 the date hereof whose election,

               individual were a member of the Incumbent Board, but excluding,
               for this purpose, any such individual whose initial assumption of

               Combination"), in each case, unless, following such Business
               Combination, (a) 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, (b)
               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 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 (c) 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

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

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

7.  General Provisions
    ------------------

    (a)  Either the Board of Directors of the Corporation or the Committee may
         modify or amend the Plan, in whole or in part, from time to time, or
         terminate the Plan at any time, without the consent of any Participant
         or Beneficiary of any Participant; provided, however, that any
         modification, amendment or termination shall be of general application
         to all Participants and Beneficiaries and shall not, without the
         consent of the Participant or, in the event of his death, the
         Participant's Beneficiary or estate adversely affect (i) any amount
         theretofore deferred or credited to the Participant's Account(s) or
         (ii) the right of the Participant to receive all amounts theretofore
         credited to the Participant's account(s), as of the date of such
         modification, amendment or termination; and provided further that any
         modification, amendment or termination that would materially increase
         or accelerate the payment of any amount under the Plan shall be
         approved by the Board of Directors. The Plan shall remain in effect
         until terminated pursuant to this paragraph.

    (b)  No rights under the Plan may be transferred or assigned except that a
         Participant may designate, in writing filed with the Secretary of the
         Corporation, 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.

    (c)  The Committee shall have full power to administer and interpret the
         Plan and to adopt such rules, regulations, procedures and resolutions
         consistent

                                      -8-
<PAGE>
 
         with the terms of the Plan as the Committee deems necessary or
         advisable to carry out the terms of the Plan.

    (d)  The place of administration of the Plan shall be conclusively deemed to
         be within the Commonwealth of Pennsylvania, and the validity,
         construction, interpretation and administration of the Plan, and of any
         determinations or decisions made thereunder, and the rights of any and
         all persons having or claiming to have any interest therein or
         thereunder, shall be governed by, and determined exclusively and solely
         in accordance with, the internal laws of the Commonwealth of
         Pennsylvania.

INDEPENDENT AUDITORS' REPORT
 
To the Board of Directors and Shareholders of PPG Industries, Inc.:
We have audited the accompanying balance sheet of PPG Industries, Inc. and sub-
sidiaries as of December 31, 1997 and 1996, and the related statements of in-
come and cash flows for each of the three years in the period ended December
31, 1997. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.
 We conducted our audits in accordance with generally accepted auditing stan-
dards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of mate-
rial misstatement. An audit includes examining, on a test basis, evidence sup-
porting the amounts and disclosures in the financial statements. An audit also
includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement pre-
sentation. We believe that our audits provide a reasonable basis for our opin-
ion.
 In our opinion, such financial statements present fairly, in all material re-
spects, the financial position of PPG Industries, Inc. and subsidiaries as of
December 31, 1997 and 1996, and the results of their operations and their cash
flows for each of the three years in the period ended December 31, 1997 in con-
formity with generally accepted accounting principles.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
- --------------------------------------------------------------------------------
PERFORMANCE IN 1997 COMPARED WITH 1996
Overall Performance
Our sales increased 2% in 1997 to $7.4 billion from $7.2 billion in 1996. Over-
all, the sales increase was due to a 6% increase in sales volumes, including
sales from recent business acquisitions in our coatings segment, offset in part
by a 2% decrease in sales prices and a 2% decline from foreign currency trans-
lation due to the strong U.S. dollar. Slightly higher sales prices for certain
products in our chemicals and coatings segments were substantially offset by
lower sales prices for caustic soda in our chemicals segment and overall lower
sales prices across the majority of our glass product lines.
 The gross profit percentage increased to 40.4% from 39.9% in the prior year.
The benefits realized from improved manufacturing efficiencies, particularly in
our glass and chemicals segments, favorable sales mix changes within our chemi-
cals and coatings segments, and slightly higher sales prices and lower raw ma-
terials costs within our coatings segment contributed to the increase. These
improvements were partially offset by lower overall sales prices in our glass
segment and for caustic soda in our chemicals segment, and the negative effects
of inflation on our glass and chemicals segments.
 Net income and earnings per common share for 1997 were $714 million and $3.97,
respectively, compared with $744 million and $3.96, respectively, for 1996. Net
income in 1997 was affected by the same factors as gross profit. In addition,
these earnings were adversely affected by pre-tax business divestiture and re-
alignment charges of $102 million associated with our glass operations; higher
overhead costs associated with growth initiatives in our coatings segment; in-
creased advertising, selling and environmental expenses in our chemicals seg-
ment; the negative effects of inflation and foreign currency translation, and a
slight increase in interest costs associated with higher outstanding
borrowings. These negative factors were offset in part by a pre-tax $59 million
gain from the sale of our surfactants business and lower income tax expense.
Reduced average shares outstanding, as a result of repurchases of common stock
by the Company, also favorably affected earnings per common share for 1997.
 
Results of Business Segments
Coatings sales increased 5% to $3.1 billion for 1997 from $2.9 billion for
1996. A 7% sales volume increase, including sales from recent business acquisi-
tions, and a 1% increase in overall sales prices were partially offset by a 3%
decline from foreign currency translation. Volume increases for automotive
original and industrial coatings and improved sales prices for automotive
refinish products in North America and Europe and for North American industrial
coatings were partially offset by lower sales prices for our automotive origi-
nal coatings products in North America and Europe. Operating income increased
to $568 million in 1997, compared with $529 million in the prior year. The
earnings improvement was attributable to the same volume and price factors that
contributed to the sales increase, combined with lower raw material costs and
slightly improved manufacturing efficiencies. These improvements were offset in
part by higher overhead costs associated with growth initiatives, particularly
in South America and Asia, the negative effects of inflation and foreign cur-
rency translation, and higher legal expenses.
 Glass sales remained relatively constant at $2.7 billion in 1997 and 1996. A
5% increase in sales volumes was offset by declines of 3% each related to sales
prices and foreign currency translation. Although volumes increased for fiber
glass products, worldwide automotive original glass products, flat glass in
North America and Europe, and aircraft products, these increases were offset by
lower sales prices for fiber glass, flat glass and automotive original glass
products in North America and Europe. Operating income decreased to $330 mil-
lion in 1997 compared with $431 million in the prior year. The decrease was at-
tributable to fourth-quarter pre-tax charges totaling $65 million for restruc-
turing actions related principally to the closing of our Perry, Ga., float
glass plant, the sales price reductions mentioned above, the negative effects
of inflation and foreign currency translation, and slightly higher legal ex-
penses. Improved worldwide manufacturing efficiencies and increased overall
volumes partially offset these unfavorable factors.
 Chemicals sales totaled $1.6 billion for 1997, up 2% from 1996. A 6% increase
in sales volumes was substantially offset by a 3% decline in overall sales
prices and a 1% decline from foreign currency translation. Volume increases for
chlorine and caustic soda products, and for certain specialty chemical prod-
ucts, particularly Transitions(R) optical lenses, and higher selling prices for
chlorine, vinyl chloride monomer and other chlorine derivative products were
offset by significantly lower selling prices for caustic soda, reduced volumes
for vinyl chloride monomer and the absence of sales from our surfactants busi-
ness divested late in 1997. Operating income increased to $430 million in 1997
from $376 million in 1996, and included a $59 million pre-tax gain from the
sale of our surfactants business. Excluding this gain, operating earnings de-
clined $5 million. The favorable effects of volume increases for specialty
chemicals and chlor-alkali products, price improvements for chlorine, vinyl
chloride monomer and other chlorine derivative products, and improved manufac-
turing efficiencies associated with chlor-alkali products were more than offset
by the decline in sales prices for caustic soda, increased advertising and
selling expenses, principally for Transitions(R) optical lenses,

the negative effects of inflation on raw material costs, and higher environmen-
tal and legal expenses.
 
Other Significant Factors
The increase in other unallocated corporate expenses-net from $11 million in
1996 to $56 million in 1997 was primarily attributable to a fourth-quarter pre-
tax charge of $37 million related to the planned disposition of our equity in-
terests in two Asian float glass plants and lower earnings from our equity af-
filiates.
 The reduction in income tax expense and the overall effective tax rate in 1997
were principally attributable to realization of capital losses associated with
the disposition of certain non-U.S. affiliates, which offset certain capital
gains, a portion of which had been taxed in a previous year.
 The increase in accounts receivable and inventories principally related to the
fourth-quarter 1997 acquisitions by our coatings and chemicals segments. Higher
sales volume in 1997 also contributed to the increase in accounts receivable,
while anticipated volume increases in 1998 contributed to the increase in in-
ventories. Partially offsetting these increases was the negative effect of
translating foreign subsidiary accounts receivable and inventory balances into
U.S. dollars.
 The increase in other current assets is due to the inclusion of the net assets
of the European decorative coatings business of Max Meyer Duco, S.p.A., which
we expect to sell in 1998.
 Other long-term assets increased because of goodwill and other intangible as-
sets resulting from 1997 acquisition activity and an increase in our prepaid
pension asset.
 Increases in accounts payable and accrued liabilities resulted from business
acquisitions and the accrual of a restructuring reserve. However, these in-
creases were partially offset by the effect of translating foreign subsidiary
liability balances into U.S. dollars.
 The decrease in the 1997 year-end discount rate from the prior year end in-
creased the additional minimum pension liability accrual and produced an ad-
justment in the shareholders' equity section of the balance sheet.
 
Outlook
PPG's strategy to focus on new product development and positioning as a low-
cost producer will likely result in increased volume in many of our businesses,
despite the expected slowing in the economic growth rate of the United States
and a slight improvement in growth in Europe in 1998. In addition, volume will
benefit from the impact of a full year's results from businesses acquired in
1997. The current economic weakness in Asia could have an impact on all of our
businesses and may cause certain chemicals prices to weaken in 1998. However,
to the extent this occurs, PPG may also benefit as certain raw material costs
in the chemicals and coatings industries may decrease and inflationary pres-
sures, particularly in North America, may be reduced and further extend the
economic expansion. PPG's diversification of product lines and worldwide mar-
kets served tend to reduce the overall impact on results of operations or
changes in demand for a particular product line or in a particular geographic
area.
 
Accounting Standards
During the first quarter of 1997, the Company adopted the provisions of State-
ment of Position (SOP) No. 96-1, "Environmental Remediation Liabilities." The
adoption of SOP No. 96-1 did not have a material impact on the Company's finan-
cial position or results of operations in 1997 and did not affect the Company's
cash flow.
 In June 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards (SFAS) No. 131, "Disclosures about Segments of
an Enterprise and Related Information," which is effective for fiscal years
beginning after Dec. 15, 1997. The Company is currently evaluating the impact
of this new standard on its current reporting of operating segment information
in its annual financial statements.
 
Business Divestitures and Realignments
We approved a program in late 1997 to restructure certain glass businesses that
were not meeting strategic and performance objectives. The principal components
of this program include the closure of our Perry, Ga., flat glass plant and the
sale of our equity interests in two Asian float glass plants, which are ex-
pected to be completed in 1998. We recorded a pre-tax charge of $102 million in
1997 to reflect the estimated cost of this program. Asset write-offs comprise
$61 million of the total charge. The remaining $41 million will require cash
outlays primarily for severance (317 employees), a proportionate share of eq-
uity investee indebtedness, and demolition and environmental costs, net of es-
timated proceeds from sale. No significant amounts had been paid as of Dec. 31,
1997, and substantially all of these cash payments will be made in 1998.
 The loss on the disposition of our equity interests in two Asian float glass
plants is based upon management's best estimate of the amounts expected to be
realized on the sale of these facilities. Due in part to the current Asian eco-
nomic instability, the proceeds the Company will ultimately realize on these
sales could, in the near term, differ from the amounts assumed in arriving at
the $37 million pre-tax charge on the disposition of these investments.
 PPG's European flat and automotive glass businesses are not performing at lev-
els that meet the Company's strategic and performance objectives. As a result,
management is in

                      MANAGEMENT'S DISCUSSION AND ANALYSIS

the process of evaluating available options to restructure these businesses.
This evaluation process is expected to be completed in the next several months.
 
PERFORMANCE IN 1996 COMPARED WITH 1995
Overall Performance
Our sales in 1996 increased 2% to $7.2 billion from $7.1 billion in 1995.
Contributing to the overall sales increase was a 3% increase in sales volumes,
which was partially offset by a 1% decrease in overall sales prices and the
unfavorable effects of foreign currency translation. Higher volumes from each
of our business segments, including sales from several small acquisitions, and
higher sales prices in our coatings segment contributed to the increase.
Partially offsetting these improvements were the absence of sales from our
divested European architectural coatings business and sodium chlorate business
and lower sales prices for our chemicals and glass segments.
 The gross profit percentage decreased to 39.9% in 1996 from 40.3% in 1995.
Contributing to the decline were lower overall sales prices and the negative
overall effect of inflation as the unfavorable impacts in our glass and chemi-
cals segments were partially offset by lower raw material costs in our coatings
segment. The positive effects of improved manufacturing efficiencies in each of
our business segments only partially offset these unfavorable factors.
 Net income for 1996 was $744 million compared with $768 million for 1995.
Earnings per share rose to $3.96 from $3.80 in 1995. Included in 1995's net in-
come was an after-tax gain of $24 million ($0.12 per share) from a legal set-
tlement of a glass technology dispute with Pilkington plc of England. Our 1996
earnings were affected unfavorably by lower other earnings, the decline in our
gross profit percentage, increased interest expense and higher minority inter-
est attributable in part to increased earnings from our majority-owned subsidi-
ary Transitions Optical, Inc. Our other earnings in 1996 declined due to gains
from legal settlements in 1995, the most significant of which was the settle-
ment with Pilkington, and lower earnings from equity affiliates in 1996 than in
1995. Interest expense in 1996 increased as a result of higher overall
borrowings, partially offset by lower average interest rates in 1996 compared
with 1995.
 These negative factors were partially offset by higher overall sales volumes
in each of our business segments and lower other charges. The majority of the
decline in other charges in 1996 was attributable to lower environmental ex-
pense and the settlement of a legal dispute in 1995. Additionally, the benefits
of ongoing overhead cost reduction actions were more than offset by the nega-
tive effects of inflation.
 While the effective tax rate for both 1996 and 1995 was 38%, income tax ex-
pense decreased slightly because of lower pretax earnings. Reduced average
shares outstanding, due to repurchases of PPG common stock by the Company, fa-
vorably affected earnings per share during 1996.
 
Results of Business Segments
Coatings sales increased 3% to $2.9 billion for 1996 from $2.8 billion for
1995, while operating income increased to $529 million from $469 million. A 2%
increase in sales volumes and a 1% increase in overall sales prices contributed
to the overall sales increase. Improved volumes in North America, higher sales
prices in most of the segment's major businesses, and sales from several small
acquisitions were partially offset by the absence of sales from our European
architectural coatings business divested late in 1995. The increase in operat-
ing income in 1996 was the result of the factors that contributed to the sales
increase, lower raw material costs, reduced overhead costs and improved manu-
facturing efficiencies. These positive factors were partially offset by the
negative effects of inflation on overhead costs in 1996 and gains from two le-
gal settlements included in 1995 operating income.
 Glass sales for 1996 were $2.7 billion compared with $2.65 billion for 1995. A
4% increase in sales volumes was partially offset by decreases of 1% each re-
lated to overall sales prices and foreign currency translation. Operating in-
come was $431 million compared with $479 million in 1995. The benefits of im-
proved volumes in North America and higher sales prices for fiber glass and
North American automotive replacement glass products were partially offset by
lower worldwide flat glass prices, particularly in Europe, and lower European
volumes. Operating income in 1995 included the gain from the legal settlement
with Pilkington. Also contributing to the decline in operating income in 1996
were lower sales prices for our flat glass and automotive original glass prod-
ucts and the negative effects of inflation. Higher fiber glass sales prices,
improved manufacturing efficiencies, increased overall volumes and lower over-
head costs only partially offset these negative factors.
 Chemicals sales were $1.61 billion for 1996 compared with $1.6 billion for
1995, while operating income for the same periods was $376 million and $383
million, respectively. Sales volumes increased 4% overall and were substan-
tially offset by a 3% decrease in overall sales prices and the unfavorable ef-
fects of foreign currency translation. We experienced volume improvements in
most of the segment's major businesses, particularly Transitions(R) lenses and
silica products, and higher prices for our specialty chemical products. Sub-
stantially offsetting these benefits were lower prices for chlor-alkali prod-
ucts and the absence of sales

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
- --------------------------------------------------------------------------------
from our sodium chlorate business, which was divested in late 1995. The de-
crease in operating income in 1996 is attributable to lower chlor-alkali sales
prices, the negative effects of inflation and increased overhead costs in sup-
port of the growth in the Transitions/R/ lens business. These negative factors
were only partially offset by the benefits of volume improvements, lower envi-
ronmental expense, the absence of a charge for a legal dispute and improved
manufacturing efficiencies.
 
Other Significant Factors
The increase in other unallocated corporate expenses--net in 1996 was primarily
attributable to lower earnings from our equity affiliates.
 
COMMITMENTS AND CONTINGENT LIABILITIES, INCLUDING ENVIRONMENTAL MATTERS
PPG is involved in a number of lawsuits and claims, both actual and potential,
including some which it has asserted against others, in which substantial money
damages are sought. These lawsuits and claims relate to product liability, con-
tract, patent, antitrust, environmental and other matters arising out of the
conduct of PPG's business. PPG's lawsuits and claims against others include
claims against insurers and other third parties with respect to actual and con-
tingent losses related to environmental matters. Management believes that the
outcome of all lawsuits and claims involving PPG, in the aggregate, will not
have a material effect on PPG's consolidated financial position, results of op-
erations or liquidity.
 It is PPG's policy to accrue expenses for environmental contingencies when it
is probable that a liability has been incurred and the amount of loss can be
reasonably estimated. Reserves for environmental contingencies are exclusive of
claims against third parties and are not discounted. As of Dec. 31, 1997 and
1996, PPG had reserves for environmental contingencies totaling $100 million
and $91 million, respectively. Pre-tax charges against income for environmental
remediation costs in 1997, 1996 and 1995 totaled $34 million, $27 million and
$49 million, respectively, and are included in "Other charges" in the statement
of income. Cash outlays related to such charges aggregated $25 million, $36
million and $39 million in 1997, 1996 and 1995, respectively.
 Management anticipates that the resolution of the Company's environmental con-
tingencies, which will occur over an extended period of time, will not result
in future annual charges against income that are significantly greater than
those recorded in recent years. It is possible, however, that technological,
regulatory and enforcement developments, the results of environmental studies
and other factors could alter this expectation. In management's opinion, the
Company operates in an environmentally sound manner and the outcome of the
Company's environmental contingencies will not have a material effect on PPG's
financial position or liquidity.
 In addition to the amounts currently reserved, the Company may be subject to
loss contingencies related to environmental matters estimated to be as much as
$200 million to $400 million, which range is unchanged from the prior year end.
Such unreserved losses are reasonably possible but are not currently considered
to be probable of occurrence. Although insurers and other third parties may
cover a portion of these costs, to the extent they are incurred, any potential
recovery is not included in this unreserved exposure to future loss. The
Company's environmental contingencies are expected to be resolved over an ex-
tended period of time.
 Although the unreserved exposure to future loss relates to all sites, a sig-
nificant portion of such exposure involves three operating plant sites and one
closed plant site. Initial remedial actions are occurring at these sites. Stud-
ies to determine the nature of the contamination are reaching completion and
the need for additional remedial actions, if any, is presently being evaluated.
The loss contingencies related to the remaining portion of such unreserved ex-
posure include significant unresolved issues such as the nature and extent of
contamination, if any, at sites and the methods that may have to be employed
should remediation be required.
 With respect to certain waste sites, the financial condition of any other po-
tentially responsible parties also contributes to the uncertainty of estimating
PPG's final costs. Although contributors of waste to sites involving other po-
tentially responsible parties may face governmental agency assertions of joint
and several liability, in general, final allocations of costs are made based on
the relative contributions of wastes to such sites. PPG is generally not a ma-
jor contributor to such sites.
 The impact of evolving programs, such as natural resource damage claims, in-
dustrial site reuse initiatives and state voluntary remediation programs, also
adds to the present uncertainties with regard to the ultimate resolution of
this unreserved exposure to future loss. The Company's assessment of the poten-
tial impact of these environmental contingencies is subject to considerable un-
certainty due to the complex, ongoing and evolving process of investigation and
remediation, if necessary, of such environmental contingencies.
 
Impact of Inflation
PPG's financial statements are prepared on a historical cost basis, which does
not completely account for the effects of inflation. Since the cost of most of
the Company's inventories is determined using the last-in, first-out (LIFO)
method,
 
                                       24
<PAGE>
 
                      MANAGEMENT'S DISCUSSION AND ANALYSIS
- --------------------------------------------------------------------------------
the cost of sales reported in the financial statements approximates current
costs.
 In 1997 and 1996, our operating results were negatively affected as increased
production costs, resulting from inflation, were not fully recovered through
price increases and manufacturing efficiencies. In 1995 the negative effects of
inflation on our costs were more than offset, for the Company as a whole, by a
combination of price increases and improved manufacturing efficiencies. While
inflationary pressure on costs is expected to continue, we anticipate that on-
going improvements in operating efficiencies, as well as raw material substitu-
tion and increases in selling prices for certain products, will mitigate to a
significant extent the negative impact of inflation on 1998 operating income.
 
FINANCIAL RESOURCES, CAPITAL SPENDING
Over the past three years, we continued to have sufficient financial resources
to meet operating requirements, to fund our capital spending, share repurchase
programs and pension contributions, and to pay increased dividends to share-
holders. Cash from operating activities was $1,007 million in 1997, $1,008 mil-
lion in 1996 and $1,072 million in 1995. Dividends paid to shareholders totaled
$239 million in 1997, $237 million in 1996 and $239 million in 1995. Contribu-
tions to U.S. pension plans totaled $109 million and $146 million in 1996 and
1995, respectively.
 During 1997, 1996 and 1995, the Company repurchased approximately 5.3 million,
11.9 million and 13.5 million shares of common stock at a cost of $302 million,
$606 million and $585 million, respectively, under various share repurchase
programs, the most recent of which authorized the repurchase of 10 million
shares of common stock, and was initiated in July 1996. As of Dec. 31, 1997,
9.9 million shares of common stock had been repurchased under the most recent
program at a cost of $553 million. The repurchase of common stock was financed
principally by cash from operations and proceeds from long-term debt.
 In 1997 long-term debt was increased principally by the issuance of $450 mil-
lion of notes at rates ranging from 6 1/4% to 6 7/8% partially offset by sched-
uled debt repayments. In 1996 long-term debt was increased principally by the
issuance of $150 million of callable 7 3/8% notes partially offset by scheduled
debt repayments. In 1995 long-term debt was increased principally by the issu-
ance of $100 million of non-callable 6 7/8% notes partially offset by scheduled
debt repayments. The proceeds from the issuance of the notes were used for gen-
eral corporate purposes, including the repayment of commercial paper
borrowings.
 Capital spending in 1997 totaled $829 million, compared with $489 million in
1996 and $454 million in 1995. This spending related to modernization and pro-
ductivity improvements, expansion of existing businesses, environmental control
projects and, in 1997, 1996 and 1995, business acquisitions totaling $363 mil-
lion, $13 million and $6 million, respectively. Additionally, a 1995 acquisi-
tion was financed through issuance of treasury stock with a market value ap-
proximating $15 million. Capital spending of a similar nature, excluding
acquisitions, is expected to total about $600 million during 1998.
 In 1998 the Company will continue to implement its acquisition strategy fo-
cused on areas of recognized strength. It is anticipated that any acquisitions
completed will be funded through a combination of cash generated from opera-
tions and external funding sources.
 The ratio of total debt, including capital leases, to total debt and equity
was 40% and 37% at Dec. 31, 1997 and 1996, respectively. Cash from operations
and the Company's debt capacity are expected to continue to be sufficient to
fund capital spending, dividend payments, share repurchases and operating re-
quirements.
 See Note 6, Debt and Bank Credit Agreements and Leases, for details regarding
the use and availability of committed and uncommitted lines of credit.
 In addition to the lines of credit, the Company may issue up to $500 million
aggregate principal amount under a shelf registration statement filed with the
Securities and Exchange Commission in January 1998.
 
MARKET RISK
PPG is exposed to certain market risks arising from transactions that are
entered into in the normal course of business. The Company may enter into
derivative financial instrument transactions in order to manage or reduce this
market risk. PPG's policies do not permit active trading of, or speculation in,
derivative financial instruments. A discussion of the Company's primary market
risk exposures and the management of those exposures is presented below.
 PPG generates revenues and costs that are subject to fluctuations due to
changes in foreign currency exchange rates when transactions are denominated in
currencies other than the functional currency. Since the Company manufactures
its products in a number of locations around the world, principally North Amer-
ica and Europe, it has a cost base that is diversified over a number of differ-
ent currencies as well as the U.S. dollar, which serves to counterbalance par-
tially its foreign currency transaction risk.
 PPG manages its foreign currency transaction risk to minimize the volatility
of cash flows caused by currency fluctuations by forecasting foreign currency
denominated cash flows of each subsidiary for a 12-month period and aggregating
these cash inflows and outflows in each currency to determine the overall net
transaction exposures. Decisions on whether to use derivative financial instru-
ments to hedge
 
                                       25
<PAGE>
 
                      MANAGEMENT'S DISCUSSION AND ANALYSIS
- --------------------------------------------------------------------------------
the net transaction exposures are made based on the amount of those exposures,
by currency, and an assessment of the near-term outlook for each currency. The
Company's policy permits the use of forward and option contracts (foreign cur-
rency contracts) to hedge approximately 30% to 70% of its anticipated net for-
eign currency cash flows over the next 12-month period. PPG does not hedge its
exposure to translation gains and losses; however, by borrowing in local cur-
rencies, it reduces such exposure. The Company does not hedge its foreign cur-
rency exposures in a manner that eliminates the effect of changes in foreign
currency rates on consolidated net income. The fair value of the foreign cur-
rency contracts outstanding as of Dec. 31, 1997 and 1996, was not material. The
market value of such contracts has a high correlation to the price changes in
the currencies of the related hedged transactions. The potential reduction in
PPG's future earnings resulting from an adverse change in the hedged currencies
of its outstanding foreign currency contracts in the amount of 10% for European
currencies and 20% for Asian and Latin American currencies would total approxi-
mately $5 million. In addition, PPG has foreign currency denominated debt of
$405 million. A weakening of the U.S. dollar relative to this foreign currency
denominated debt of 10% for debt denominated in European currencies and 20% for
debt denominated in Asian and Latin American currencies would result in an
unrealized translation loss of approximately $52 million.
 The Company manages its interest rate risk in order to balance its exposure
between fixed and variable rates while attempting to minimize its interest
costs. Generally, the Company maintains variable interest rate debt at a level
of 25% to 50% of total borrowings. PPG principally manages its interest rate
risk by retiring and issuing debt from time to time. To a limited extent, PPG
manages its interest rate risk through the use of interest rate swaps. As of
Dec. 31, 1997 and 1996, the fair value of interest rate swaps was not material.
A 10% increase in interest rates would affect PPG's variable rate debt
obligations and reduce future earnings by approximately $3 million. Further, a
10% reduction in interest rates would increase the present value of the
Company's fixed rate debt by approximately $58 million, which would not have a
near-term impact on PPG's future earnings or cash flows.
 The Company enters into commodity swap and option contracts to reduce its
exposure to fluctuations in prices for natural gas. The fair value of these
contracts as of Dec. 31, 1997 and 1996, was not material. As a result of a 10%
reduction in the price of natural gas, the Company would experience a potential
loss in the fair value of the underlying commodity swap and option contracts as
of Dec. 31, 1997, of approximately $8 million.
 
YEAR 2000
The Company has initiated a program to prepare its computer systems and
applications for the year 2000. As part of this program, a review has been
performed of key financial, business and operational systems, and plans have
been developed to implement the required system modifications, and remediation
efforts are under way.
 The Company expects to utilize both internal staff and outside consulting
firms to complete the necessary system modifications, and anticipates that the
associated costs to address this issue will not be material. It is anticipated
that these costs will be largely funded from systems maintenance budgets. The
Company is also contacting suppliers to obtain their assurance of year 2000
compliance.

- --------------------------------------------------------------------------------
Nature of Operations
PPG is a multinational manufacturer engaged in three lines of business:
coatings, glass and chemicals. The coatings business supplies a variety of
protective and decorative coatings and finishes along with adhesives, sealants
and metal pretreatment products for automotive original equipment and
aftermarket refinish, industrial and architectural applications. The glass
business supplies flat and continuous-strand fiber glass for residential and
commercial construction, automotive original and replacement, other
transportation and industrial applications. The chemicals business supplies
chlor-alkali and specialty chemical products. The primary chlor-alkali products
are chlorine, caustic soda, vinyl chloride monomer, chlorinated solvents and
chlorinated benzenes. The primary specialty chemical products are Transitions(R)
lenses, optical monomers, silicas, surfactants (until December 1997) and fine
chemicals. Production facilities and markets for the coatings and glass
businesses are predominantly in North America and Europe, while the chemicals
business operates primarily in North America. Most coatings and glass products
are sold directly to manufacturing and construction companies, although in
some instances products are sold directly to independent distributors and mass
merchants, and through PPG distribution outlets. Most chlor-alkali and
specialty chemical products are sold directly to manufacturing companies in the
chemical processing, rubber and plastics, paper, minerals and metals, water
treatment, pharmaceutical and optical industries. Each of the businesses in
which PPG is engaged is highly competitive. However, the diversification of
product lines and worldwide markets served tends to minimize the impact on
total sales and earnings of changes in demand for a particular product line or
in a particular geographic area.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Principles of consolidation
The consolidated financial statements include the accounts of PPG Industries,
Inc. (PPG or the Company) and all significant subsidiaries, U.S. and non-U.S.,
of which we own more than 50% of the voting stock. Investments in companies of
which we own 20% to 50% of the voting stock are carried at equity, and our
share of the earnings or losses of such equity affiliates is included in the
statement of income. Transactions between PPG and its subsidiaries are elimi-
nated in consolidation.
 
Use of estimates in the preparation of financial statements
The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions
that affect the reported amounts of assets and liabilities and the disclosure
of contingent assets and liabilities at the date of the financial statements,
as well as the reported amounts of income and expenses during the reporting pe-
riod. Actual results could differ from those estimates.
 
Foreign currency translation
For all significant non-U.S. operations, the functional currency is the local
currency. Assets and liabilities of those operations are translated into U.S.
dollars using year-end exchange rates; income and expenses are translated using
the average exchange rates for the reporting period. Translation adjustments
are deferred as a separate component of shareholders' equity.
 
Inventories
Most U.S. and certain non-U.S. inventories are stated at cost, using the last-
in, first-out (LIFO) method, which does not exceed market. Other inventories
are stated at the lower of cost or market. We determine cost using either aver-
age or standard factory costs, which approximate actual costs, excluding cer-
tain fixed costs such as depreciation and property taxes.
 
Property
Property is recorded at cost. We compute depreciation by the straight-line
method based on the estimated useful lives of depreciable assets. Additional
expense is recorded when facilities or equipment are subject to abnormal eco-
nomic conditions or obsolescence. Significant improvements that add to produc-
tive capacity or extend the lives of properties are capitalized. Costs for re-
pairs and maintenance are charged to expense as incurred. When property is
retired or otherwise disposed of, the cost and related depreciation are removed
from the accounts and any related gains or losses are included in income. Amor-
tization of the cost of capitalized leased assets is included in depreciation
expense.
 
Goodwill
Goodwill, representing the excess of the cost over the net tangible and identi-
fiable intangible assets of acquired businesses, is stated at cost and is amor-
tized on a straight-line basis over the estimated future periods to be bene-
fited (15 to 40 years). The Company evaluates the recoverability of goodwill at
each balance sheet date and would record an impairment if necessary.
 
Employee Stock Ownership Plan
We account for our employee stock ownership plan (ESOP) in accordance with
Statement of Position (SOP) No. 93-6 for PPG common stock purchased after Dec.
31, 1992 (new ESOP shares). As permitted by SOP No. 93-6, shares purchased
prior to Dec. 31, 1992 (old ESOP shares), continue to be accounted for in ac-
cordance with SOP No. 76-3. ESOP shares are released and allocated to partici-
pants based upon debt service paid during the year on loans used by the ESOP to
purchase the shares. Unearned compensation, reflected as a reduction of share-
holders' equity, principally represents the unpaid balance of such ESOP loans.
Dividends received by the ESOP are used to pay debt service.
 For old ESOP shares, compensation expense is equal to amounts contributed, or
committed to be contributed, to the ESOP by the Company less the ESOP interest
expense element of such contributions. Dividends on old ESOP shares are de-
ducted from retained earnings. Old ESOP shares are considered to be outstanding
in computing earnings per share.
 For new ESOP shares, compensation expense is equal to the Company's matching
contribution (see Note 8). Dividends on released new ESOP shares are deducted
from retained earnings, and dividends on unreleased shares are reported as a
reduction of debt or accrued interest. Only new ESOP shares that have been
released are considered outstanding in computing earnings per share.
 
Cash equivalents
Cash equivalents are highly liquid investments (valued at cost, which approxi-
mates fair value) acquired with an original maturity of three months or less.
 
Derivative instruments
Derivative financial instruments are used to hedge a portion of the Company's
foreign currency and interest rate exposures. Income and expense are recorded
in the same caption as that arising from the related asset or liability being
hedged. Premiums paid on option contracts are amortized over the lives of the
contracts.
 Gains and losses related to hedges of firm commitments are deferred and recog-
nized over the expected remaining lives of the related assets and liabilities.

and losses from option contracts that hedge anticipated transactions are also
deferred and recognized in income in the same period as the hedged transac-
tions. Unrealized gains and losses from forward contracts that hedge antici-
pated transactions are not deferred.
 The Company also uses commodity swap and option contracts to reduce its expo-
sure to fluctuations in prices for natural gas. Gains and losses on these con-
tracts are deferred and recognized in income in the same period as the hedged
transactions as an adjustment to cost of sales.
 The fair value of derivative instruments held as of Dec. 31, 1997 and 1996,
was not material. The Company does not enter into derivative transactions for
speculative purposes and therefore holds no derivative instruments for trading
purposes.
 
2. ACQUISITIONS, BUSINESS DIVESTITURES AND REALIGNMENTS
During 1997, we acquired several businesses, all of which were recorded using
the purchase method of accounting and, accordingly, the results of operations
of the acquired companies have been included in our consolidated results from
their respective acquisition dates. In September 1997, we acquired the U.S. in-
dustrial pretreatment business of Man-Gill Chemical Company; in November 1997,
we acquired Max Meyer Duco S.p.A. (Max Meyer), a European supplier of automo-
tive refinish, fleet finish and decorative coatings, and Phillips Paint Prod-
ucts, a Canadian industrial coatings manufacturer; and in December 1997, we ac-
quired the worldwide packaging coatings businesses of BASF Lacke + Farben AG, a
German company, Keeler & Long, a U.S. manufacturer of high-performance coatings
and coil coatings, and Sipsy Chimie Fine S.C.A., a French manufacturer of phar-
maceutical intermediates and formerly a wholly owned subsidiary of Warner Lam-
bert Company. During 1997, we also increased our ownership interest from 45% to
100% in two related automotive original coatings companies located in Brazil
and Argentina. The cost of these 1997 acquisitions was $363 million plus the
assumption of $42 million in indebtedness.
 We expect to sell the European decorative coatings business of Max Meyer in
1998. Therefore, the net assets of that business are reflected as "Other cur-
rent assets" in the balance sheet at Dec. 31, 1997.
 The preliminary purchase price allocations for these acquisitions used in
preparing the Dec. 31, 1997, balance sheet are subject to adjustment in 1998
when finalized. On a pro forma basis, if these acquisitions had occurred
effective as of Jan. 1, 1996, they would have contributed approximately $300
million to net sales in both 1997 and 1996. The pro forma effect of these
acquisitions on net income and earnings per share in 1997 and 1996 would not be
material. The pro forma financial information is not necessarily indicative of
the operating results that would have occurred had the acquisitions been
consummated as of Jan. 1, 1996, nor are they necessarily indicative of future
operating results.
 Business divestitures completed in 1997, primarily the sale of the surfactants
business, resulted in a net pre-tax gain of $58 million. Net sales associated
with these businesses totaled $111 million in 1997, $122 million in 1996 and
$119 million in 1995.
 We also approved a program in late 1997 to restructure certain glass
businesses that were not meeting strategic and performance objectives. The
principal components of this program include the closure of our Perry, Ga.,
flat glass plant and the sale of our equity interests in two Asian float glass
plants, which are expected to be completed in 1998. We recorded a pre-tax
charge of $102 million in 1997 to reflect the estimated cost of this program.
Asset write-offs comprise $61 million of the total charge. The remaining $41
million will require cash outlays primarily for severance (317 employees), a
proportionate share of equity investee indebtedness, and demolition and
environmental costs, net of estimated proceeds from sale. No significant
amounts had been paid as of Dec. 31, 1997, and substantially all of these cash
payments will be made in 1998.
 The loss on the disposition of our equity interests in two Asian float glass
plants is based upon management's best estimate of the amounts expected to be
realized on the sale of these facilities. Due in part to the current Asian eco-
nomic instability, the proceeds the Company will ultimately realize on these
sales could, in the near term, differ from the amounts assumed in arriving at
the $37 million pre-tax charge on the disposition of these investments.
 
3. SHAREHOLDERS' EQUITY
A class of 10 million shares of preferred stock, without par value, is autho-
rized but unissued. Common stock has a par value of $1.66 2/3 per share and 600
million shares are authorized. Shares outstanding at Dec. 31, 1997 and 1996,
exclude unreleased new ESOP shares (see Note 8).
 PPG has a Shareholders' Rights Plan, under which each share of the Company's
outstanding common stock has an associated preferred share purchase right. The
rights are exercisable only under certain circumstances and allow holders of
such rights to purchase common stock of PPG or an acquiring company at a dis-
counted price, which generally would be 50% of the respective stocks' current
fair market value.
 Per share cash dividends paid were $1.33 in 1997, $1.26 in 1996 and $1.18 in
1995.

(1) See Note 8 for discussion of ESOP borrowings. The fixed- and variable-rate
    notes mature in 2009 and require annual principal payments from 1998 to

Aggregate maturities during the next five years are (in millions) $56 in 1998,
$171 in 1999, $32 in 2000, $32 in 2001 and $137 in 2002.
 The Company has revolving credit agreements with credit lines totaling $820
million. Of these credit lines, $800 million will expire in December 2001 and
require payment of annual fees equal to seven basis points on the unused por-
tion of the lines. These lines support our commercial paper programs in the
United States, Canada and the Netherlands. The remaining $20 million, relating
to a subsidiary, will expire in September 1998 and requires payment of annual
fees equal to 10 basis points on the unused portion of the line. PPG may cancel
all or part of these credit agreements at any time without penalty or premium.
At Dec. 31, 1997, we had used $10 million of these lines of credit.
 Our non-U.S. operations have other committed and uncommitted lines of credit
totaling $21 million and $554 million, respectively, of which $14 million and
$264 million, respectively, were used at Dec. 31, 1997. The committed lines of
credit, which expire during the years 1998 and 1999, do not require significant
commitment fees. The uncommitted lines of credit are subject to cancellation at
any time and are not subject to any commitment fees.
 PPG is in compliance with the restrictive covenants under its various credit
agreements, loan agreements and indentures.
 The Dec. 31, 1997 and 1996, balances for "Short-term debt and current portion
of long-term debt" include, respectively, $34 million and $423 million of com-
mercial paper and $354 million and $173 million of short-term notes. The

and 1996, were 6.0% and 5.5%, respectively.
 Interest payments in 1997, 1996 and 1995 totaled $106 million, $109 million
and $91 million, respectively.

8. EMPLOYEE STOCK OWNERSHIP PLAN
Our employee stock ownership plan (ESOP) covers substantially all U. S. employ-
ees. The Company makes matching contributions to the ESOP based upon partici-
pant's savings, subject to certain limitations, the matching percentage being
based upon our return on average equity for the previous year.
 In 1989 and 1990, the ESOP purchased 13,400,334 shares of PPG common stock
(old ESOP shares) from the Company and on the open market. The ESOP purchased
471,526, 506,761 and 631,748 shares of PPG common stock (new ESOP shares) on
the open market in 1997, 1996 and 1995, respectively. The ESOP financed these
purchases through a combination of borrowings guaranteed by PPG and borrowings
directly from PPG. Borrowings from third-parties to finance these purchases are
included in debt in our balance sheet (see Note 6).
 Compensation expense related to the ESOP for 1997, 1996 and 1995 totaled $11
million, $15 million and $18 million, respectively. Interest expense totaled
$11 million, $11 million and $12 million for 1997, 1996 and 1995, respectively.
Dividends on PPG shares held by the ESOP, to service ESOP debt, totaled $39
million, $37 million and $34 million for 1997, 1996 and 1995, respectively. The
fair value of unreleased new ESOP shares was $13 million and $12 million at

 At Dec. 31, 1997, subsidiaries of the Company had available net operating loss
(NOL) carryforwards of approximately $75 million for income tax purposes, of
which $56 million have an indefinite expiration. The remaining $19 million ex-
pire between the years 2001 and 2003.
 The majority of the NOL carryforwards relate to operations of subsidiaries in
countries permitting indefinite carryforward of losses. Generally, the valua-
tion allowance has been established for these carryforwards because the ability
to utilize them is uncertain.
 The significant decreases in the operating loss and other carryforwards and
the related valuation allowance are attributable to the dispositions of certain
non-U.S. subsidiaries. These dispositions also generated U.S. capital losses of
approximately $183 million, of which $85 million was utilized in 1997 and $98
million was carried forward. A valuation allowance has been established for
these carryforwards because the ability to utilize them is uncertain. These
carryforwards expire Jan. 1, 2003.
 Income before income taxes of our non-U.S. operations for 1997, 1996 and 1995
was $232 million, $266 million and $257 million, respectively.
 No deferred U.S. income taxes have been provided on certain undistributed
earnings of non-U.S. subsidiaries, which amounted to $495 million at Dec. 31,
1997, and $511 million at Dec. 31, 1996. These earnings are considered to be
reinvested for an indefinite period of time or will be repatriated when it is
tax effective to do so. It is not practicable to determine the deferred tax li-
ability on these earnings.
 The Internal Revenue Service has examined our U.S. federal income tax returns
through 1990, and we have paid all tax claims.
 Income tax payments in 1997, 1996 and 1995 totaled $452 million, $402 million
and $358 million, respectively.

11. STOCK OPTION PLAN
Under PPG's stock option plan, certain employees of the Company have been
granted options to purchase shares of common stock at prices equal to the fair
market value of the shares on the date the option was granted. Options are ex-
ercisable beginning from six to 12 months after granting and have a maximum
term of 10 years. Shares available for future grants were 10,029,300 and
1,429,883 at Dec. 31, 1997 and 1996, respectively.
 PPG applies Accounting Principles Board Opinion No. 25, "Accounting for Stock
Issued to Employees," and related interpretations in accounting for its stock-
based compensation. Accordingly, no compensation cost for PPG's stock option
plan has been recognized in the accompanying financial statements. Had compen-
sation cost been determined based upon the fair value at the grant date for

awards granted in 1997, 1996 and 1995 consistent with the methodology pre-
scribed in SFAS No. 123, "Accounting for Stock-Based Compensation," net income
and earnings per common share would have been reduced by $20 million and $0.11
per common share in 1997, $16 million and $.09 per common share in 1996 and $10
million and $.05 per common share in 1995. The fair value of stock options is
estimated at the grant date using the Black-Scholes option pricing model with
the following weighted average assumptions.

14. PENSIONS AND OTHER POSTRETIREMENT BENEFITS
Pension benefits
We have noncontributory defined benefit pension plans that cover certain em-
ployees worldwide. Benefits under these plans are based on years of service and
salaries or on stated amounts for each year of service. Our funding policy for
all plans is consistent with applicable governmental requirements. We provide
for obligations for all plans by depositing funds with trustees, by purchasing
insurance policies or by recording financial statement accruals. Pension plan
assets held in trust consist of equity securities and fixed-income investments.
 Net periodic pension (income) cost includes the following components:

(1) As of Dec. 31, 1997 and 1996, the prepaid pension amounts are included in
 Other assets in the balance sheet.
 
 We determined the projected benefit obligation using weighted-average discount
rates of 7.0% at Dec. 31, 1997, and 7.5% at Dec. 31, 1996. For those plans that
provide benefits based on salaries in the final years of employment, the
assumed long-term rate of increase in salaries was 4.6% at Dec. 31, 1997 and
1996. The accrued pension liability, reflected in the balance sheet, included
$4 million at Dec. 31, 1997 and 1996, for defined contribution plans.
 Total pension (income) cost, which includes costs for defined contribution
plans, multi-employer defined benefit pension plans and the net periodic pen-
sion (income) cost shown above, was $(22) million, $4 million and $8 million in
1997, 1996 and 1995, respectively.
 
Other postretirement benefits
PPG sponsors defined benefit plans that provide medical and life insurance ben-
efits to nearly all of its retired employees in the United States and certain
retired employees in Canada. These plans also cover the employees' spouse and
dependents. Salaried and certain wage employees hired after Jan. 31, 1993, will
not be entitled to postretirement medical benefits. At Dec. 31, 1997, the U.S.
plans had provisions that capped the cost of postretirement medical benefits at
2003 levels for most current and future retirees covered by bargaining plans,
as well as current and future retirees covered by nonbargaining plans. Many of
our plans include cost-sharing provisions, such as co-insurance and deduct-
ibles, and require participant contributions based upon elected coverage. The
plans also coordinate benefits with Medicare for those employees who are 65 and
older or transfer the health care risk to Medicare health maintenance organiza-
tions. Life insurance benefits for retirees covered by nonbargaining plans are
calculated at a percentage of the retirees' final base pay. For most bargaining
units, the benefits are based upon negotiated flat dollar amounts. Our Canadian
plans provide postretirement medical and life insurance benefits that supple-
ment benefits provided and paid for under the Canadian health care system. The
Company's postretirement medical and life insurance plans are unfunded.
 Net periodic postretirement benefit cost includes the following components:

 The weighted-average discount rate used in determining the APBO was 7.0% at
Dec. 31, 1997, and 7.5% at Dec. 31,
1996. The weighted-average assumed health care cost trend rate was 7.3% for
1997 and 7.0% for 1998, declining ratably to 4.0% by the year 2007. If these
trend rates were increased by one percentage point per year, the APBO and the
aggregate of the service and interest cost components of the net periodic
postretirement benefit cost would increase by approximately 4.7% and 4.2%, re-
spectively.
 
15. COMMITMENTS AND CONTINGENT LIABILITIES
PPG is involved in a number of lawsuits and claims, both actual and potential,
including some which it has asserted against others, in which substantial money
damages are sought. These lawsuits and claims relate to product liability, con-
tract, patent, antitrust, environmental and other matters arising out of the
conduct of PPG's business. PPG's lawsuits and claims against others include
claims against insurers and other third parties with respect to actual and
contingent losses related to environmental matters. Management believes that
the outcome of all lawsuits and claims involving PPG, in the aggregate, will
not have a material effect on PPG's consolidated financial position, results of
operations or liquidity.
 It is PPG's policy to accrue expenses for environmental contingencies when it
is probable that a liability has been incurred and the amount of loss can be
reasonably estimated. Reserves for environmental contingencies are exclusive of
claims against third parties and are not discounted. As of Dec. 31, 1997 and
1996, PPG had reserves for environmental contingencies totaling $100 million
and $91 million, respectively. Pre-tax charges against income for environmental
remediation costs in 1997, 1996 and 1995 totaled $34 million, $27 million and
$49 million, respectively, and are included in "Other charges" in the statement
of income. Cash outlays related to such charges aggregated $25 million, $36
million and $39 million in 1997, 1996 and 1995, respectively.
 Management anticipates that the resolution of the Company's environmental con-
tingencies, which will occur over an extended period of time, will not result
in future annual charges against income that are significantly greater than
those recorded in recent years. It is possible, however, that technological,
regulatory and enforcement developments, the results of environmental studies
and other factors could alter this expectation. In management's opinion, the
Company operates in an environmentally sound manner and the outcome of the
Company's environmental contingencies will not have a material effect on PPG's
financial position or liquidity.
 In addition to the amounts currently reserved, the Company may be subject to
loss contingencies related to environmental matters estimated to be as much as
$200 million to $400 million, which range is unchanged from the prior year end.
Such unreserved losses are reasonably possible but are not currently considered
to be probable of occurrence. Although insurers and other third parties may
cover a portion of these costs, to the extent they are incurred, any potential
recovery is not included in this unreserved exposure to future loss. The
Company's environmental contingencies are expected to be resolved over an ex-
tended period of time.
 Although the unreserved exposure to future loss relates to all sites, a sig-
nificant portion of such exposure involves three operating plant sites and one
closed plant site. Initial remedial actions are occurring at these sites. Stud-
ies to determine the nature of the contamination are reaching completion and
the need for additional remedial actions, if any, is presently being evaluated.
The loss contingencies related to the remaining portion of such unreserved ex-
posure include significant unresolved issues such as the nature and extent of
contamination, if any, at sites and the methods that may have to be employed
should remediation be required.
 With respect to certain waste sites, the financial condition of any other po-
tentially responsible parties also contributes to the uncertainty of estimating
PPG's final costs. Although contributors of waste to sites involving other po-
tentially responsible parties may face governmental agency assertions of joint
and several liability, in general, final allocations of costs are made based on
the relative contributions of wastes to such sites. PPG is generally not a ma-
jor contributor to such sites.
 The impact of evolving programs, such as natural resource damage claims, in-
dustrial site reuse initiatives and state voluntary remediation programs, also
adds to the present uncertainties with regard to the ultimate resolution of
this unreserved exposure to future loss. The Company's assessment of the poten-
tial impact of these environmental contingencies is subject to considerable un-
certainty due to the complex, ongoing and evolving process of investigation and
remediation, if necessary, of such environmental contingencies.
 
16. FINANCIAL INSTRUMENTS
Included in PPG's financial instrument portfolio are cash and cash equivalents,
Company-owned life insurance, derivative financial instruments and short- and
long-term debt instruments. The most significant instrument, long-term debt
(excluding capital lease obligations), had carrying and fair values totaling
$1,272 million and $1,362 million, respectively, at Dec. 31, 1997. The corre-
sponding amounts at Dec. 31, 1996, were $858 million and $903 million, respec-
tively. The fair values of the other instruments approximated their carrying
values, in the aggregate.
 The fair values of the debt instruments were based upon quoted market prices
of the same or similar instruments or on the rates available to the Company for
instruments of the same remaining maturities.

All amounts are in millions of dollars except per share data and number of
employees.
Data was adjusted, as appropriate, to reflect the two-for-one stock splits
payable on June 10, 1994, and on March 12, 1987.
(1) The 1993 changes in methods of accounting relate to the adoption of SFAS
    No. 106, "Employers' Accounting for Postretirement Benefits Other Than
    Pensions"; SFAS No. 109, "Accounting for Income Taxes," and SFAS No. 112,
    "Employers' Accounting for Postemployment Benefits." The 1991 change in the
    method of accounting relates to the cost of rebuilding glass and fiber
    glass melting facilities. The effect of all the changes on net income in
    the years of change, exclusive of the cumulative effect to Jan. 1 of the
    year of change and the pro forma effect on individual prior years' net
    income, was not material.
(2) Return on average capital and return on average equity for 1993 and 1991
    were calculated and presented inclusive and exclusive of the cumulative
    effect of the accounting changes.
(3) Return on average capital is calculated using pre-interest, after-tax
    earnings and average debt and equity during the year.
(4) Includes the cost of businesses acquired.
(5) Price/earnings ratios were calculated based on high and low market prices
    during the year and the respective year's earnings per common share. The
    1993 and 1991 ratios were calculated and presented exclusive of the
    cumulative effect of the accounting changes.
